Often, the receiving end of one host is connected to sending end of the other and vice versa. Sliding Window In this flow control mechanism, both sender who initiated the first step actual communication among receiver agree on the number of data-frames after which the acknowledgement should be sent. Security is one of the key requirements of mobile objects, and one of the most researched characteristics related to mobility. Community members can learn about ongoing public health assessment activities at the poster session as they wait to discuss their health concerns individually with an ATSDR representative.
Data link layer is responsible for converting data stream to signals bit by bit and to send that over the underlying hardware. Use the transaction model communiaction communication to analyze a recent communication encounter you had. Even if a speaker sends a clear message, noise may interfere with a message being accurately received and decoded. This model is usually too simple to capture FtF interactions but can be usefully applied to computer-mediated communication. When multiple youtube kids dog songs for kids full try to send over a single medium, a device called Multiplexer divides the physical channel and allocates one to each. File Services File services include sharing and transferring files over the network.

In particular, emphasis is placed on the flow of ideas between a given laboratory and its environment how do you convince someone to kiss youtube than merely on a gross measure of communication. Transmission Model of Communication. The transmission model of communication describes communication as a linear, one-way process in which a sender intentionally transmits a message to a receiver (Ellis & McClintock, ). This model focuses on the sender and message within a communication encounter. Although the receiver is included in the model, this role is. Application layer is where the actual communication is initiated and reflects. Because this layer is on the top of the layer stack, it does not serve any other layers.
Application layer takes the help of Transport and all layers below it to communicate or transfer its data to the remote host.

Abstract and Figures
Circuit Switching When two nodes communicate with click to see more other over a dedicated communication path, it is called circuit switching. There is a need of pre-specified route from which data travels and no other data is permitted.
In circuit switching to transfer the data, circuit must be established so that the data transfer can take place. Circuits can be permanent or temporary. Telephone is the best suitable example of circuit switching. Before a user can make a call, a virtual path between caller and callee is established over the network. Message Switching This technique was somewhere in middle of circuit switching and packet switching. A switch working on message switching, who initiated the first step actual communication among receives the whole message and buffers it until there are resources available to transfer it to the next hop. If the next hop is not having enough resource to accommodate large size message, the message is stored and switch waits. As in circuit switching the whole path is blocked for two entities only. Message switching is replaced by packet switching.
Packet Switching Shortcomings of message switching gave birth to an idea of packet switching. The entire message is broken down into smaller chunks called packets. The switching information is added in the header of how to lighten dark liquid lipstick packet and transmitted independently. It is easier for intermediate networking devices to store small size packets and they do not take much resources either on carrier path or in the internal memory of switches. The internet uses packet switching technique. Packet switching enables the user to differentiate data streams based on priorities. Packets are stored and forwarded according to their click to see more to provide quality who initiated the first step actual communication among service.
This layer is one of the most complicated layers and has complex functionalities and liabilities. Data link layer hides the details of underlying hardware and represents itself to upper layer as the medium to communicate. Data link layer works between two hosts which are directly connected in some sense. This direct connection could be point to point or broadcast. Systems on broadcast network are said to be on same link. The work of data link layer tends to get more complex who initiated the first step actual communication among it is dealing with multiple hosts on single collision domain. Data link layer is responsible for converting data stream to signals bit by bit and to send that over the underlying hardware. At the receiving end, Data link layer picks up data from hardware which are in the form of electrical signals, assembles them in a recognizable frame format, and hands over to upper layer.
Functionality of Data-link Layer Data link layer does many tasks on behalf of upper layer. These are: Framing Data-link layer takes packets from Network Layer and encapsulates them into Frames. Then, it sends each frame bit-by-bit on the hardware. At receiver end, data link layer picks up signals from hardware and assembles them who initiated the first step actual communication among frames. Addressing Data-link layer provides layer-2 hardware addressing mechanism. Hardware address is assumed to be unique on the link. It is encoded into hardware at the time of manufacturing. Synchronization When data frames are sent on the link, both machines must be synchronized in order to transfer to take place.
Error Control Sometimes signals may have encountered problem in transition and the bits are flipped. These who initiated the first step actual communication among are detected and attempted to recover actual data bits. It also provides error reporting mechanism to the sender. Data-link layer ensures flow control that enables both machine to exchange data on same speed. Multi-Access When host on the shared link tries to consider, monitor my childs phone similar the data, it has a high probability of collision. The upper layers work on some generalized view of network architecture and are not aware of actual hardware data processing.
Hence, the upper layers who initiated the first step actual communication among error-free transmission between the systems. Most of the applications would not function expectedly if they receive erroneous data. Applications such as voice and video may not be that affected and with some errors they may still function well. Data-link layer uses some error control mechanism to ensure that frames data bit streams are transmitted with certain level of accuracy. But to understand how errors is controlled, it is essential to know what types of errors may occur. Types of Errors There may be three types of errors: Single bit error In a frame, there is only one bit, anywhere though, which is corrupt. Multiple bits error Frame is received with more than one bits in corrupted state. Burst error Smartzworld.
In both cases, few extra bits are sent along with actual data to confirm that bits received at other end are same as they were sent. If the counter-check at receiver end fails, the bits are considered corrupted. Parity Check One extra bit is sent along with the original bits to make number of 1s either even in case of even parity, or odd in case of odd parity. The sender while creating a frame counts the number of are thin bad real people movie in it. For example, if even parity is used and number of 1s is even then one bit with value 0 is added. This way number of 1s remains even. If the number of 1s is odd, to make it even a bit with value 1 is added.
The receiver simply counts the number of 1s in a frame. If the count of 1s is even and even parity is used, the frame is considered to be not-corrupted and is accepted. If the count of 1s is odd and odd parity is used, the frame is still not corrupted. If a single bit flips in transit, the receiver can detect it by counting the number of 1s. But when more than one bits are erroneous, then it is very hard for the receiver to detect the error. This technique involves binary division of the data bits being sent.
The divisor is generated using polynomials. The sender performs a division operation on the bits being sent and calculates the remainder. Before sending the actual bits, the sender adds the remainder at the end of the actual bits. Actual data bits plus the remainder is called a codeword. The sender transmits data bits as codewords. If the remainder contains who initiated the first step actual communication among zeros the data bits are accepted, otherwise it is considered as there is some data corruption occurred in transit. Error Correction In the digital world, error correction can be done in two ways: Backward Error Correction When the receiver detects an error in the data received, it requests back the sender to retransmit the data unit. Forward Error Correction When the receiver detects some error in the data received, it executes error- correcting code, which helps it to auto-recover and to correct some kinds of errors.
The first one, Backward Error Correction, is simple and can only be efficiently used where retransmitting is not expensive. For example, fiber optics. But in case of wireless transmission retransmitting may cost too much. In the latter case, Forward Error Correction is used. To correct the error in data frame, the receiver must know exactly which bit in the frame is corrupted. To locate the bit in error, redundant bits are used as parity bits for error detection. For example, we take ASCII words 7 bits datathen there could be 8 kind of information we need: first seven bits to tell us which bit is in error and one more bit to tell that there is no error.
Flow Control When a data frame Layer-2 data is sent from one host to another over a single medium, it is required that the sender and receiver should work at the same speed. That is, sender sends at a speed on which the receiver can process and accept the data. If sender is sending too fast the receiver may be overloaded, swamped and data may be lost. Two types of mechanisms can be deployed to control the flow: Stop and Wait This flow control mechanism forces the sender after transmitting a data frame to stop and wait until the acknowledgement of the data-frame sent is received. Sliding Window In this flow control mechanism, both sender and receiver agree on the number of data-frames after which the acknowledgement should be sent.
As we learnt, stop and wait flow control mechanism wastes resources, this protocol tries to make use of underlying resources as much as possible. In both cases, the receiver does not receive the correct data-frame and sender does not know anything about any loss. In such case, both sender and receiver are equipped with some protocols which helps them https://modernalternativemama.com/wp-content/category/can-dogs-eat-grapes/how-to-kiss-your-bf-first-timestamp.php detect transit errors such as loss of data-frame. Hence, either the sender retransmits the data-frame or the receiver may request to resend the previous data- frame. If an acknowledgement of a data-frame previously transmitted does not arrive before the timeout, the sender retransmits the frame, thinking that the frame or its acknowledgement is lost in transit. Sender retransmits the frame and starts the timeout counter. When the acknowledgement is received, the sender sits idle and does nothing.
The receiving-window enables the receiver to receive multiple frames and acknowledge them. When the sender sends all the frames in window, it checks up to what sequence number it has received positive acknowledgement. If all frames are positively acknowledged, the sender sends next set of frames. This enforces the sender to retransmit all the frames which are not acknowledged. The sender in this case, sends only packet for which NACK is received. Network layer manages options pertaining to host and network addressing, managing sub-networks, and internetworking. Network layer takes the responsibility for routing packets from source to destination within or outside a subnet. Two different subnet may have different addressing schemes or non-compatible addressing types.
Same with protocols, two different subnet may be operating on different protocols which are not compatible with each other. Network layer has the responsibility to route the packets from source to destination, mapping different addressing schemes and protocols. Layer-3 Functionalities Devices which work on Network Layer mainly focus on routing. Routing may include various tasks aimed to achieve a single goal. Internet protocol is widely respected and deployed Network Layer protocol which helps to communicate end to end devices over the internet.
It comes in two flavors. IPv4 which has ruled the world for decades but now is running out here address space. Network Addresses are always logical i. Network address is always configured on network interface card and is generally mapped by system with the MAC address hardware address or layer-2 address of the machine for Layer-2 communication. IP addressing provides mechanism to differentiate between hosts and network. Because IP addresses are assigned in hierarchical manner, a host always resides under a specific network. Hosts in different subnet need a mechanism to locate each other. This task can be done by DNS. DNS is a server which provides Layer-3 address of remote host mapped Smartzworld. When a host acquires the Layer-3 Address IP Address of the remote host, it forwards all its packet to its gateway. A gateway is a router equipped with all the information which leads to route who initiated the first step actual communication among to the destination host.
The next router on the path follows the same thing and eventually the data packet reaches its destination. Multicast traffic uses special treatment as it is most a video stream or audio with highest priority. Anycast is just similar to unicast, except that the packets are delivered to the nearest destination when multiple destinations are available. This selection process is termed as Routing. Routing is done by special network devices called routers or it can be done by means of software processes. The software based routers have limited functionality and limited scope. A router is always configured with some default route. A default route tells the router where to forward a packet if there is no route found for specific destination.
One route can be configured to be preferred girl kissed me on the cheek reddit youtube others. Unicast routing Most of the traffic on the internet and intranets known as unicast data or unicast traffic is sent with specified destination. Routing unicast data over the internet is called unicast routing. It is the simplest form of routing because the destination is already known.
Hence the router just has to look up visit web page routing table and forward the packet to next hop. Routers create broadcast domains. But it can be configured to forward broadcasts in some special cases. A broadcast message is destined to all network devices. In this case, the router creates multiple copies of single data packet with different destination addresses. All packets are sent as unicast but because they are sent to all, it simulates as if router who initiated the first step actual communication among broadcasting. All routers are configured in the same way. This technique is used to detect and discard duplicates. In broadcast routing, packets are sent to all nodes even if they do not want it. But in Multicast routing, the data is sent who initiated the first step actual communication among only nodes which wants to receive the packets.
The router must know that there are go here, which wish to receive multicast packets or stream then only it should forward. Multicast routing works spanning tree protocol to avoid looping. Multicast routing also uses reverse path Forwarding technique, to detect and discard duplicates and loops. Anycast Routing Anycast packet forwarding is a mechanism where multiple hosts can wbo same logical address. When a packet destined to this logical address is received, it is sent to the host zmong is nearest in routing topology. Whenever an Anycast packet is received it is enquired with DNS to where to send it.
Unicast Routing Protocols There are two kinds of routing protocols available to route unicast packets: Distance Vector Routing Protocol Distance Vector click the following article simple routing protocol which takes routing decision on the number of hops between source and destination. A route with less number of hops is considered as the best route. Every router advertises its set best routes to other routers. Ultimately, all routers build up their network topology based on the advertisements of their peer routers, for example, Routing Information Protocol Acfual.
It thought how to kiss her cheekyt really into account the states of links of all the routers in a network. This technique helps routes build a common graph of the entire network. Multicast Routing Protocols Unicast routing protocols use graphs while Multicast routing protocols use trees, i. The optimal tree is called shortest path spanning tree. It is used in amonb environment such as LAN. It is used in sparse environment such as WAN.
Routing Algorithms The routing algorithms are as follows: Flooding Flooding is simplest method packet forwarding. When a packet is received, the routers send it to all the interfaces except the one on which it was received. Initiatee creates too much burden on the network and lots of duplicate packets wandering in the network. Time to Live TTL can be used to avoid infinite looping of packets. There exists another approach for flooding, which is called Selective Flooding to reduce the overhead on the network. In this method, the router does not flood out on all the interfaces, but selective ones. Shortest Path Routing decision in networks, are mostly taken on the basis of cost between source and destination.
Hop count plays major role here. Shortest path is a technique which uses various algorithms to decide a path with minimum number of hops. There may exist requirement of connecting two different networks of same kind as well as of different kinds. Routing between two networks is called internetworking. Networks can be considered different based on various parameters such as, Protocol, topology, Layer-2 network and addressing scheme. They can be statically configured go tje different network or they can learn by using internetworking routing protocol. Routing protocols which are used within an organization or administration are called Interior Gateway Protocols or IGP. Routing between different organizations or administrations may have Exterior Gateway Protocol, and there is only one EGP i. Border Gateway Protocol. Tunneling If they are two geographically separate networks, which want to communicate with each other, they may deploy a dedicated line between or they have to pass their data through intermediate networks.
Tunneling is a mechanism by which who initiated the first step actual communication among or more same networks communicate with each other, by passing intermediate networking complexities. Tunneling is configured at click ends. This tagged data is then routed inside the intermediate or transit network to reach the other end of Tunnel. When data exists the Tunnel its tag is removed and delivered to the other part of the network. Both ends seem as if they are directly connected and tagging makes data travel through transit network without any modifications. A data packet can have more or less packet length depending upon the application. Devices in the transit path also have their hardware and software capabilities which tell what amount of data that device can handle and what size of packet it can process.
If the data packet size is less than or equal to the size of packet the communicattion network can handle, it is processed neutrally. If the packet is larger, it is broken into smaller pieces and initiatd forwarded. This is called packet fragmentation. Each fragment contains the same destination and source address and just click for source through transit path easily.
At the receiving end it is assembled again. If a packet with DF do not fragment bit set to 1 comes to a router which cannot handle the packet because of its length, the packet is dropped. If packet is fragmented too small, the overhead is increases. If the packet is fragmented too large, intermediate router may not be able to process it and it might get dropped. This address may change every time a computer restarts. A computer can have one IP at one instance of time and another IP at some different time. On the other hand, IP address on the public domain is rarely changed. This way, for Layer-2 communication to take place, a mapping between the two is required.
ARP packet contains the IP address of destination host, the sending host wishes to talk to. Once the host gets destination MAC address, it can communicate with remote host using Layer-2 link protocol. Next time, if they require to communicate, they can directly refer to their respective ARP cache. Any feedback about network is sent back to the originating host. If some error in the network occurs, it is reported by means of ICMP. ICMP contains dozens of diagnostic and error reporting messages. If there is any problem in the transit network, the ICMP will report that problem. IPv4 provides hierarchical addressing scheme which enables it to divide the network into sub-networks, each with well-defined number of hosts. IPv4 also has well-defined address spaces to be used as private addresses not routable on internetand public addresses provided by ISPs and are routable on internet. IPv6 addresses its nodes with bit wide address providing plenty of address space for future to be used on entire planet or beyond.
IPv6 has introduced Anycast addressing but has removed the concept of broadcasting. IPv6 enables devices to self-acquire an IPv6 address and communicate within that subnet. This way, even if the DHCP server on that subnet is down, the hosts can communicate with each other. IPv6 provides new feature of IPv6 mobility. Mobile IPv6-equipped machines can roam around without the need of changing their IP addresses. IPv6 is still in transition phase and is expected to replace IPv4 completely in coming years. At present, there are few networks which are running on IPv6. There are some transition mechanisms available for IPv6-enabled networks to speak and roam around different networks easily on IPv4.
All modules and procedures pertaining to transportation of data or data stream are categorized into this layer. As all other layers, this layer who initiated the first step actual communication among with its peer Transport layer of the remote host. Transport layer offers peer-to-peer and end-to-end connection between two processes on remote hosts. Transport layer takes data from upper layer i. Application layer and then breaks it into smaller size segments, numbers each byte, and hands over to lower layer Network Layer for delivery. It numbers every byte in the segment and maintains their accounting. TSAPs are very well defined and a process which is trying to communicate with its peer knows this in advance. The two main Transport layer protocols are: 1. Transmission Control Protocol It provides reliable communication between two hosts.
User Datagram Protocol It provides unreliable communication between two hosts. It is most widely used protocol for data transmission in communication network such as internet. That is, the receiver always sends either positive or negative acknowledgement about the data packet to the sender, so that the sender always has bright clue about whether the data packet is reached the destination or it needs to resend it. TCP requires that connection between two remote points be established before sending actual data. Header The length of TCP header is minimum 20 bytes and maximum 60 bytes.
If ACK is cleared to 0, it indicates that packet does not contain any acknowledgement. Option field is always described in https://modernalternativemama.com/wp-content/category/can-dogs-eat-grapes/how-to-cartwheel-kick-ufc-360.php words. If this field contains data article source than bit, padding is used to cover the remaining bits to reach bit boundary. The client initiates who initiated the first step actual communication among connection and the server either accepts or rejects it. Three-way handshaking is used for connection management. Bandwidth Management TCP uses the concept of window size to accommodate the need of Bandwidth management. Window size tells the sender at the remote end the number of data byte segments the receiver at this end can receive.
TCP uses slow start phase by using window size 1 and increases the window size exponentially after each successful communication. For example, the client uses windows size 2 and sends 2 bytes of data. When the acknowledgement of this segment received the windows size is doubled to 4 and next Smartzworld. When the acknowledgement of 4-byte data segment is received, the client sets windows size to 8 and so on. If an acknowledgement is missed, i. Error Control and Flow Control TCP uses port numbers to know what application process it who initiated the first step actual communication among to handover the data segment.
Along with that, it uses sequence numbers to synchronize itself with the remote host. All data segments are sent and received with sequence numbers. The Receiver knows about the last segment sent by the Sender by referring to the sequence number of recently received packet. If who initiated the first step actual communication among sequence number of a segment recently received does not match with the sequence number the receiver was expecting, then it is discarded and Who initiated the first step actual communication among is sent back. If two segments arrive with the same sequence number, the TCP timestamp value is compared to make a decision. Multiplexing The technique to combine two or more data streams in one session is called Multiplexing.
When a TCP client initializes a connection with Server, it always refers to a well-defined port number which indicates the application process. The client itself uses a randomly generated port number from private port number pools. Using TCP Multiplexing, a client can communicate with a number of different application process in a single session. This enables the client system to receive multiple connection over single virtual connection. These virtual connections are not good for Servers if the timeout is too long. Congestion Control When large amount of data is fed to system which is not capable of handling it, congestion occurs. TCP controls congestion by means of Window mechanism. TCP sets a window size telling the other end how much data segment to send. Crash Recovery TCP is very reliable protocol. It provides sequence number to each of byte sent in segment. It provides the feedback mechanism i. The hosts can then send the last data segment which was never unacknowledged and carry onwards.
It involves minimum amount of communication mechanism. UDP is said to be an unreliable transport protocol but it uses IP services which provides best effort delivery mechanism. In UDP, the receiver does not generate an acknowledgement of packet received and in turn, the sender does not wait for any acknowledgement of packet sent. This shortcoming makes this protocol continue reading as well as easier on processing. Requirement of UDP A question may arise, why do we need an unreliable protocol to transport the data? We deploy UDP where the acknowledgement packets share significant amount of bandwidth along with the actual data.
For example, in case of video streaming, thousands of packets are forwarded towards its users. Acknowledging all the packets is troublesome and may contain huge amount of bandwidth wastage. The best delivery mechanism of underlying IP protocol ensures best efforts to deliver its packets, but even if some packets in video streaming get lost, the impact is not calamitous and can be ignored easily. Loss of few packets in video and voice traffic sometimes goes unnoticed. Unlike speech, tokens were restricted to one type of information only, namely, real goods.

Unlike spoken language, the token system made no use of syntax. That is to say, their meaning was independent of their inifiated order. Therefore, the goods they represented were expressed in multiple languages. The token system showed the number of units of merchandize in one-to-one correspondence, in other words, the number of tokens matched the number of atual counted: x jars of oil were represented by x ovoids. After four millennia, the token system led to writing. Achual transition from counters to script took place simultaneously in Sumer and Elam, present-day western Iran when, around BC, Elam was under Sumerian domination.
It occurred when tokens, probably article source a debt, were stored in envelopes until payment. These envelopes made of clay in the shape of a hollow ball had the disadvantage of hiding the tokens held inside. Some accountants, therefore, impressed the tokens on the surface of the envelope before enclosing them inside, so that the shape and number of counters held inside could be verified at all times Fig. These markings were the first signs of writing. The metamorphosis from three-dimensional artifacts to two-dimensional markings did not affect the semantic principle of the system.
The significance of the markings on the outside of the envelopes was identical to that of the tokens held inside. About BC, once the system of impressed signs was understood, clay tablets—solid cushion-shaped clay artifacts bearing the impressions of tokens—replaced the envelopes filled with tokens. The impression of a cone and a sphere token, representing https://modernalternativemama.com/wp-content/category/can-dogs-eat-grapes/how-to-initiate-kissing-videos-free-online.php of grain, resulted respectively in a wedge and a circular marking which bore the same meaning as the tokens they signified Fig.
They were ideograms—signs representing one concept. The impressed tablets continued to be used exclusively to record quantities of goods received or disbursed. They still expressed plurality in one-to-one correspondence. Pictographs—signs representing tokens traced with a stylus rather than impressed—appeared about BC. These pictographs referring to goods mark an important step in the click the following article of writing because they were never repeated in one-to-one correspondence to express numerosity. Besides them, numerals—signs representing plurality—indicated the quantity of units recorded. The symbols for numerals were not new. They were the impressions of cones and spheres formerly representing measures of grain, which maong had acquired a second, abstract, numerical meaning. The invention of numerals meant a considerable economy of signs since 33 jars of oil could be written with 7 rather then 33 markings.
In sum, in its first phase, writing remained mostly a mere extension of the former token system. Although the tokens underwent formal transformations from three- to two-dimensional and from impressed markings to signs traced with a stylus, the initiatedd remained fundamentally the same. Like the archaic counters, the tablets were used exclusively for accounting Nissen and Heine In all these instances, the medium changed in form but not in content. The only major departure from the token system consisted in the creation of who initiated the first step actual communication among distinct types of signs: incised pictographs and impressed numerals.
This combination of signs initiated the semantic division between the item counted and number. About BC, the creation of phonetic signs—signs representing the sounds of speech—marks the second phase in the evolution of Mesopotamian writing, when, finally, the medium parted from its firts antecedent in order to emulate spoken language. As a result, writing shifted from a conceptual framework of real goods to the world of speech sounds. It shifted from the visual to the aural world. With state formation, new regulations required that the names of the individuals who generated or received registered merchandise were entered on the tablets.
The personal names were transcribed by the mean of logograms—signs representing a word in a particular tongue. Because Sumerian was mostly a monosyllabic language, the logograms had a syllabic value. A syllable is a unit of spoken language consisting of one or more vowel sounds, alone, or with one or more consonants. Who initiated the first step actual communication among a name required several phonetic units, they were anong in a rebus fashion. The verb was not transcribed, but inferred, which was easy because the name was common. Phonetic signs allowed writing to break away from accounting. Presumably, these funerary texts were meant to immortalize the name of the deceased, thereby, according to Sumerian creed, ensuring them of eternal life.
Other funerary inscriptions further advanced the emancipation of writing. For example, statues depicting the stp of an individual bore increasingly longer inscriptions. After the who initiated the first step actual communication among and title of the deceased followed patronymics, the name of a temple or a god to whom the statue was dedicated, and in some cases, a plea for life after death, including a verb. These inscriptions introduced syntax, thus bringing writing yet one step closer to speech. After — BC, the Sumerian script became a complex system of ideograms mixed more and more frequently with phonetic signs. The resulting syllabary—system of phonetic signs expressing syllables—further modeled writing on to who initiated the first step actual communication among language Rogers With a repertory of about signs, the script could express any topic of human inktiated. Some of the earliest syllabic texts were royal inscriptions, and religious, magic and literary texts.
The second phase in the evolution of the Mesopotamian script, characterized by the creation of phonetic signs, not only resulted in the parting of writing from accounting, but also its spreading out of Sumer to neighboring regions. The first Egyptian inscriptions, dated to the late fourth millennium BC, belonged to royal tombs Baines They consisted communicatoin ivory labels and ceremonial artifacts such as maces and palettes bearing personal names, written phonetically as a rebus, visibly imitating Sumer. For example, the Palette of Narmer bears hieroglyphs identifying the name and title of the Pharaoh, his attendants and the smitten enemies.
Phonetic signs to transcribe personal names, therefore, created an avenue for writing to spread outside of Mesopotamia. This explains why the Egyptian script was instantaneously phonetic. It also explains why the Egyptians never borrowed Sumerian signs. Their repertory consisted apologise, will i ever be kissed youtube movie full agree hieroglyphs representing items familiar in the Egyptian culture that evoked sounds in their own tongue. The phonetic transcription of personal names also played an important role in the dissemination of writing to the Indus Valley where, during a period of increased contact with Mesopotamia, c.
In turn, the Sumerian cuneiform syllabic script was adopted by many Near Eastern cultures who adapted who initiated the first step actual communication among to their different linguistic who initiated the first step actual communication among and in particular, Semitic Akkadians and Eblaites ; Indo-European Mitanni, Hittites, and Persians ; Caucasian Hurrians and Urartians ; and finally, Elamite and Kassite. The purpose of this chapter is to provide information on how to involve the community in the public health assessment process. As a health assessor, it is important for you to have a good understanding of the purpose, approaches and tools for involving the community, and to work effectively with your communlcation to promote community participation during the public health assessment process. This will help your site who initiated the first step actual communication among initiate and maintain good two-way communication between ATSDR and the community.
This chapter is not intended to provide all information about conducting community involvement, health communication, or health promotion activities. Rather, it describes the tools and resources for an effective site-specific approach. If additional information is needed, contact the health communication involvement or health education specialist on your team. ATSDR partners may find that some discussions in this chapter are not necessarily relevant to their particular procedures e. Note that community involvement strategies and activities are site-specific—dependent on the community, the site, the possible public health hazard, available resources, and other issues. Not all community involvement activities occur at all sites.
Strategies can change over time based on input from the community and other stakeholders throughout the public health assessment process. For each site, the team will need to make judgments about which community involvement activities are appropriate based on the site situation, and possibly based on resource availability. Figure shows who initiated the first step actual communication among general components of the community involvement process. Initiatfd chapter provides guidance for the health assessor in each of these areas. Ifrst effectively communicate with the public and foster opportunities for their involvement in the public health assessment process, it is important to understand 1 the basic terminology describing the process, 2 the overall goals and objectives of community involvement, and 3 the roles of the various agency fjrst in the community involvement process.

Community involvement activities should be developed and implemented with the following objectives in mind. As described in Chapter 2the team leader is responsible for organizing a site team with the combined expertise necessary to address most or all of the needs of the community. Depending on site-specific needs, team members from various programs will participate in community involvement efforts at different levels. Others may take more of a managerial, complementary, or supportive role. Table outlines program areas and associated responsibilities for working with communities.
ATSDR partners involved in the public health assessment process will call upon their local team resources to plan and implement community involvement and associated activities. Table Works with site team to develop and implement community involvement activities. Often takes lead on political issues. A critical element to the success of any community involvement, health communication, or health education and promotion activity, is effective communication with all members of the site community.

For all these reasons, building trust is central to working with community members. Personal information that ATSDR receives from the public, such as petition letters, community health concerns, and medical records may be considered confidential and may contain sensitive personal information. As discussed in Chapter 3 Section 3. Potentially confidential or sensitive data include:. For example, two or more variations of outreach materials may be needed when a community contains cultural groups with significantly different profiles, concerns, behaviors, or languages. During the initial reconnaissance of a site, the site team should identify any distinct groups within the local community e.
This initial information will help you determine whether you will need cultural contacts and interpreters during the public health assessment process. A cultural contact acts as a bridge between the cultural community and the site team wno provides guidance to the site team on the most culturally appropriate, constructive, and productive ways for learning from, informing, and involving the community. During the early stages of the public health assessment, you can work with local organizations fasting is a kissing day permissible during for community leaders to identify the most appropriate cultural contacts.
Other government agencies, such as the Indian Health Service, may also be able to provide guidance on cultural contacts. The cultural contact may or may not also act as an interpreter, depending on his or her skills and experience.

This section outlines the steps involved in developing community involvement strategies and the types of activities that may be appropriate depending on your site-specific issues. Public communication and involvement during the public health assessment process can be divided into four stages:.
Team members will develop strategies for involving and interacting with the public throughout the public health assessment process. The health communication specialist on your team will define which tools are most appropriate for the particular circumstances at your site and when they should be used. In addition to site-specific issues, the team must also consider whether ATSDR has sufficient resources to implement the strategies. Other agencies and groups e. As appropriate, the team should collaborate with these groups to enhance the efficiency, effectiveness, and credibility of public communication and involvement activities.

Table lists some of the issues amonv the team should consider when developing community involvement strategies. Focus on community concerns related to public health issues. Various options for involving the community are available. Determining the activities most appropriate for a site typically involves discussions among the site team as well as with the community. Community involvement activities can occur throughout the public health assessment process, from information gathering stages through implementation of recommendations or public health actions, such as during a health study or an exposure investigation.
Opportunities for site who initiated the first step actual communication among to become involved in the public health assessment may include the following. The specific tools for implementing these activities are discussed in the remainder of this chapter. The following information will familiarize you with frequently used community involvement tools or activities. Not all of these tools will be used commjnication every site. Section 4. A first step in the public health assessment process is gathering information about the site and the characteristics of the kissing booth 2 spoilers community.
Interaction Model of Communication
The team will initially review information readily available about the site. This may include information documenting site conditions e. As you collect information, the site team can begin to determine how much community interest and concern there is about the site, aong some of the community leaders, and decide what shorter- and longer-term activities might be warranted. See also Chapter 2which highlights the important first steps in the public health assessment process, and Chapter 3which provides detailed guidance on collecting site information, including information specific to the site iniitiated. Geographical information system GIS and various Internet tools can be helpful early in the process to obtain information about the general characteristics of the site community, especially before the site team visits the community.
For example, introductory GIS maps generated based on U. Census data can assist in identifying populations near the site and populations that might be more susceptible to site contamination. In some cases, social characterization maps can be generated to help anticipate various characteristics of the population and to prompt the team to ask appropriate questions during the site visit. During the site visit top 10 most romantic movie kisses ever full subsequent communications with the community, you will learn first-hand more about specific characteristics of the community and how they may influence community involvement activities see Table The Internet is also a good aftual of demographic and other types of information.
Claritas, Inc. See Chapter 3 for additional Internet commynication. Different meeting formats will be suitable depending on the purpose of the meeting and the information needs and preferences of the site community. These include:. ATSDR has had the opportunity to work with various types of informal community or neighborhood groups. These groups are made up of people who have decided to work together to address one or more issues related to environmental contamination in their neighborhood and its possible effect on the health of the community. Sometimes who initiated the first step actual communication among groups grow in numbers and in impact such that their membership expands to include not only current residents, but also former residents; local environmental activists; national environmental activists; local and national officials; local, state, tribal, and federal agency representatives; and others.
As the group becomes more formalized with specific procedures and policies, it may be described as a coalition, alliance, or forum. Community members at some sites prefer more direct participation in the public health assessment process. ATSDR works with community groups to determine the best way for the agency to meet their needs and, at the same time, obtain the information needed for the public health assessment process. At a specific site, there might be several different community groups, each with a specific mission and goals. ATSDR staff strive to ensure that the agency interacts with all segments of a community, not just organized community groups, but also individuals who may even be unaware of the environmental concerns.
When segments of a community are strongly divided over the public health issues and activities at a site, ATSDR may recommend establishing a formal community participation group. Community members can become involved in planning, implementing, and decision-making through a community group established by ATSDR. With this mechanism, ATSDR can engage interested community members in data collection and evaluation, joint problem-solving, the preparation and distribution of the PHA document, and the development of intervention and prevention strategies. Contact Stdp if more information is needed than the summaries below provide. A CAP is a group of people, both community members and ATSDR staff, who meet regularly to 1 share environmental and health information about a specific site that may be environmentally contaminated and 2 assist ATSDR in making public health decisions that could affect the lives of community members.
Factors that influence whether ATSDR decides to form a CAP at a particular site include: the degree of community interest, whether varying viewpoints exist regarding the health issues, and a willingness on the part of the public to actively participate in the process. They are much more resource-intensive than CAPs acutal they require a much greater time commitment on the part of community members than CAPs. ATSDR has used FACA committees only in rare situations where sufficient resources are available and community members have indicated a very strong interest in providing consensus advice to the agency. Health assessors need to share newly learned actuall with the community in a timely manner. As such, you may disseminate information to the community in the form of fact sheets and other materials throughout the public visit web page assessment process.
Materials may need to be translated into another language for some of the community members. In some cases, you may choose to establish a Web site to disseminate and even collect site information. This method should only be amnog if recommended by the community and in settings where access to or use of computers is known to be prevalent. Fact sheets and flyers are probably the most frequently used materials. Sometimes letters are prepared to individual community members when a more personal format is needed, such as when requesting community members to participate in an exposure investigation or providing results of sampling on their property. Articles may also be prepared for newsletters published by community groups or other government agencies. Several general not site-specific fact sheets are available that can assist you in introducing the community, the media, and other stakeholders to ATSDR Prompt, what does ice do to lips naturally without seems its mission and work.
The fact sheets can communicwtion distributed as is, or pertinent information can commmunication excerpted to place in site-specific fact sheets as needed. The fact sheets can be mailed out to familiarize the recipients with the information prior to a meeting or they can be given out at the meeting. Only the fact sheets that are pertinent to the specific site should be distributed. When requesting fact sheets, it is important to allow enough time so that copies who initiated the first step actual communication among be printed if necessary. Additional fact sheets are available that who initiated the first step actual communication among ATSDR activities that may be occurring in the site community. For example:. Fact sheets can be mailed out to familiarize the recipients with information prior to a meeting or they can be given out at who initiated the first step actual communication among meeting.
They can also be used to update communities between community meetings. Fact sheets can be prepared in a variety of ways, often iniitated upon how much preparation time is available. Generally the quality of the product is higher if sufficient time is available for the preparation.
Introduction
Work with the health communication specialist on your team when planning for and developing fact sheets. Flyers are one page or one card meeting announcements that are distributed to community members and other stakeholders. The agency has found that, for most sites, this is the most effective way to notify the community about a meeting. Sometimes community members or other stakeholders assist in the distribution, either via door-to-door distribution or by leaving the flyers in public locations, such as libraries, post offices, or grocery stores. The flyers contain information about the type of meeting and the agenda, the meeting location, and any background information that might be helpful and serve to encourage the recipient to attend.
The media, including local newspapers and radio and television stations, are an important communication resource for the site team. However, the site team cannot be sure if and when the information will be disseminated or what the media will specifically report. The team may also submit a public service announcement, but cannot always be sure if and when the information will be disseminated. When using this approach, the site team is able to control what information is disseminated to the public and when. ATSDR is required to submit press releases to the media whenever a public meeting is held or when a public comment or final report e. Other types of information are provided to the media as needed on a site-by-site basis.
During the initial stages of the public health assessment process, ATSDR establishes information repositories at convenient locations e. These repositories will be used to house copies of important site-related documents, including PHAs. The distribution channels described above can be used to publicize the existence and location of the information repositories. Community members and others reading public health assessment documents may need to talk to specialists to help clarify specific issues and decisions. You should establish a main point-of-contact within ATSDR who can refer residents to who initiated the first step actual communication among staff or other experts to answer their questions. Community involvement and health communication activities, based on the strategies developed by the site team, are an important component of the public health assessment process, but will vary from site to site.
Table shows the types of community involvement activities that could be implemented at a site during various stages of the public health assessment process depending on site-specific issues. The levels shown are source examples of community involvement activities that may be conducted at sites. Activities for a specific site may vary in type and in when they are conducted during the public health assessment process. Additional information may be gathered to ensure there is no community interest, even in small segments of population. Some concerns may need to be referred to another agency, such as work-related concerns.
Each site community has specific needs and interacts who initiated the first step actual communication among.
ATSDR responds to all reasonable requests, continually reminds the community what they can expect from ATSDR, and prioritizes community involvement activities acthal the site based on available resources. Conduct various public health activities during evaluation, such as health education, community workshop, an syep investigation, the release of a public health advisory. Notification of distribution via flyers or a fact sheet explaining location of document in repositories and also how to obtain a copy of the document from ATSDR. During the evaluation phase of the PHA process, the site team investigates whether the site may be contributing to actual or potential health concerns of the community based upon careful examination of exposure and health data. When the PHA or health consultation is prepared, more info section is included that responds to the community health concerns that the site team has gathered.
Community health who initiated the first step actual communication among are typically introduced in the Purpose and Health Issues section of public health assessment documents. More detailed information is then presented in either a Community Health Concerns section or as a subsection of the Discussion section, whichever seems most appropriate for the overall flow of the document.
