The curriculum resourcing of the teacher librarian Assignment

The curriculum resourcing of the teacher librarian - Assignment Example Once the best materials are selected, the students and the teacher will have an ample time to complete the required curriculum in the required time. The library is a celebrated institution in the life of a student. The library contains the resource that the student will need to get a better understanding of the studies he or she partakes. Hence, it should require well-informed curriculum materials. Introduction A library is a structured assortment of books, journals and even on line material an institution or community for gathering information uses that (Bishop, 2007). In the life of a student, the library offers a haven of information resource that can be used to ease the study work of the student. For students, this is usually critical because most of what they learn in school is mostly found in the library. Getting the necessary information; therefore, becomes vital to these young scholars. The resources found in the library are taken through thorough processes before they are qu alified to be included as resource materials in the library. This is because a lot of care has to be taken when these sources of information are being gathered (Church, 2007). The absolute best books and journals should be used for the accomplishment of the apprentices, and the school. The compelling thing is that libraries consisted of stone tablets that were gathered in a room for storage in the past. These shows those even in the past, libraries were significant. The processes of acquiring the libraries' resource materials have changed drastically since then (Clayton & Gorman, 2001). The process of acquisition of the resource material has become more complex with time. This is because a number of factors such as units of study or subject/topic requirement must be considered for a resource material to be selected. The student should benefit from the resources choosen, or that are available to him. Most of the learning institutions have adopted new ways to ensure this (Conger, 2004 ). The modern library can have on-line platforms and visual aid gadgets just to mention a few. This has created a bigger platform for the student to use. So what make a dependable and resourceful library? What are the acquisition and selection procedures for these resource materials? In order to answer the following question we need to understand the need to be satisfied for the curriculum point of view. Curriculum In a modern school or any other learning institution, there are sets of courses that the learner needs to cover. These courses are put in an organized manner that ease and smoothes the student’s process of learning through out the learning period. These sets and the order they are organized in is called a curriculum (Craver, 2001). For the student to pass the studies he or she is taking, they must fulfill the curriculum to the satisfaction of their teacher or examiner. For a good curriculum, some few aspects should be carefully considered. These environments surrou nd the student throughout the teacher’s course (Evans & Saponaro, 2005). They affect the learning process of the student, hence if lightly taken; the student may have trouble in his studies. One of the main aspects to be considered is the unit of works the student will have to take. The units of work are courses that student require to pass the level of education or to

Psychology Journals - Essay Example d by his belief based on his gathered evidence that the lab tests that use animal rarely result to anything that benefits humankind, that mostly are just for commercial intents. That people and animals are different species, thus using animals with people as the supposed beneficiary is not logical. in the medical sciences, research with animals has resulted in major achievements in psychology, which s/he believes have contributed to important benefits for human beings. S/he further cites that the biofeedback technique, which people use to control high blood pressure, originated from studies using lab animals. in the issue of animal cruelty, there had been a study that investigated 600 of these alleged accusations, but eventually did not support the charge of cruelty. S/he further points out that instances occur, but are infrequent and not typical of psychological experiments. people—including animal rights advocates—do not think that animals share the characteristics that allow them the same rights as humans; and these people condone pet sterilization, disregarding the animals right to breed. of the many experiments using animals, only a few contribute to important medical or psychological research. S/he further argues that a vast number of experiments are used for commercial purposes: to test new shampoos, cosmetics, food additives, or detergents. Yes, I believe both psychologists presented sound arguments based the criteria. Their claims are all verifiable, not simply opinions. They both cited sources, which can also be checked if they match. Finally, the incidents cited were more than one. Animals may be used in lab experiments as long as guidelines to the humane treatment are observed. Humans have been plagued by new diseases with some killing relentlessly, like the swine flu, among so many others. AIDS, after years of research, has yet remained incurable. If lab research using animals could give us hope in combating these diseases, then I would

The Role Of Intermediary Devices In Networks Information Technology Essay

The Role Of Intermediary Devices In Networks Information Technology Essay TCP/ IP model and OSI layers are the two network models used by the internet. In the OSI model, an Ethernet switch operates at the Data-Link layer to create a different collision domain for every single switch port. A multilayer switch though may work at more than one OSI layers, including physical, data link, network and even the transport layer. A router on the other hand is considered a layer 3- the Network layer of the TCP/IP model- device since it does most of its routing decisions according to information in the IP packet of layer 3. Role of Intermediary Devices in the network The switch, which is basically a modern and more efficient version of the outdated hub, is a network access device. The router is an internetworking device. They are both intermediary devices. The basic functionalities of the processes that run in them are to regenerate and re-transmit data, maintain information about the pathways that exist across the network and internet, inform other devices in case of errors and transmission failures, guide data along substitute pathways when there is a failure in the link, classify and direct messages according to Quality of Service (QoS) priorities and permit or deny data flow based on security settings. LANs AND WANs A Local Area Network (LAN) is a computer network which typically covers one geographical area, delivering services and applications to those within a mutual organizational structure. A switch is used to connect these computers. Switches lack the capability of connecting multiple networks or distributing an internet connection. A Wide Area Network (WAN) is a network of computers covering a broad area and is used in interconnecting two or multiple Local Area Networks. It is usually built using leased lines. A router connects two or more logical subnets and thus is usually connected to two or more LANs or WANs or also a LAN and its Internet Service Provider (ISP). Routers are also used to link segments of a LAN that has been sub-netted into smaller segments. Routers are located at gateways, the meeting point of two or more networks (Ilascu, 2007) Address Table Packet-switched computer networks employ a forwarding technique called bridging. Bridging is dependent on flooding and source address examination in received packet headers to establish the address location of unknown devices. Switches maintain a table of Ethernet MAC addresses referred to as a CAM Table also known as Bridge forwarding table using a method called Transparent Bridging involving learning, flooding, filtering, forwarding and aging. The switch records the source addresses in entries in the table, while destination addresses are looked up in the table and matched to the proper segment to send the frame. The show mac-address-table command can be used to show this table on a Cisco switch. Source route bridging is another form of bridging that was developed for token ring networks. Routers direct packets according to information stored in the IP routing table. A router looks inside each TCP/IP packet it has received to identify the IP addresses of the source and target, sear ches its own routing table for the best match between the destination IP address of the network and addresses in the routing table packet then forwards the packets as desired to ensure that data reaches its destination. The show ip route command can be used to show the table on a Cisco router. (Cisco, 2009) Security Switches and routers are often ignored as security devices because they were originally made to enhance network connectivity rather than network security. Consequently, they are conceptually less secure. An attack on the edge router can cut off the entire network from its users. Weak passwords, unneeded services, protocol and IOS vulnerabilities and IOS configuration errors can cause security breaches. Most routers nowadays have a hardware firewall integrated in their systems thus this has made routers an important component in fostering network security. There are several technical terms about switches and routers that one would encounter: Ports and interfaces A port is a point of physical access or physical interface between a circuit and a device or system at which signals are injected or extracted. It can also be a logical connection, identified by a protocol address in a packet header, associated with TCP or UDP service. The IP address and the port number identify a socket. An interface physically and logically interconnects two other devices or systems Broadcast, unicast and multicast Multicast is a transmission mode in which a signal or packet is sent to multiple devices or computers, but not all on a network, unicast is where a single packet or signal is sent to a single device and broadcast is where it is sent to all stations on a network in order to update the routing table. Gateway This is where one network meets another, for example where a LAN and a WAN are joined by a router. Protocols These are rules and conventions used to exchange information between computers or across computer internetworks. Their two major functions are handshaking and line discipline. Encapsulation and Decapsulation Different types of information are added as data from the Application layer passes down the protocol stack. A new header in each level and a new name is given to the data enclosed. Decapsulation is the reverse. As data goes up the protocol stack, the Data link layer takes it from the physical medium, does a Cyclic Redundancy Check, strips off the respective headers and the rest of the data is passed to an upper layer till it reaches the application layer. Packet switching LAN switches depend on packet-switching. A connection between two segments is established long enough to direct out the current packet. Inbound packets are stored in a temporary memory area, buffer; MAC address in the header is read and compared to those in the switchs lookup table.   An Ethernet frame comprises a normal packet as the payload of the frame, which has a special header including the MAC address information. Traffic-routing in a switch Three methods are used by packet-based switches for traffic-routing. As soon as the packet is detected by the switch, Cut-through switches read the MAC address. The 6 bytes that contain the address information are stored and instantly forwarding the packet to the destination node starts as the rest of the packet comes into the switch. In store-and-forward, the entire packet is saved by the switch, checked for CRC inaccuracies or any other problems before sending. The packet is discarded if it contains errors. The least common method is fragment-free. Its working is like that of cut-through but the first 64 bytes of the packet are stored before sending. This is because most errors and all collisions take place during the first 64 bytes of a packet. Switch configurations The physical design of LAN switches differ. Shared memory is one of the three common configurations in use. This brand of switch stores all entering packets in a common buffer memory shared by all switch ports (for input and output connections), subsequently sending them out through the correct port for the required destination node. In Matrix type of switch, there is an internal grid with input ports crossing output ports. Once a packet is identified on an input port, the MAC address is matched to the lookup table to get the suitable output port. A connection on the grid  where these two ports intersect is then made by the switch. The third is Bus architecture, where instead of a grid; an internal transmission  path (common bus) is shared by all ports using TDMA. There is a dedicated memory buffer for each port in a switch based on this configuration, with an ASIC to control the internal bus access. Router interfaces A router typically has multiple interfaces, as its main purpose is to interconnect several networks and send packets from one network to another. Every interface is a member or host belonging to a different IP network. The routing table comprises of network addresses for a routers own interfaces, which are directly connected networks, and remote networks. Though routers make their major forwarding decisions at the Network layer, router interfaces do this in Layers 1, 2, and 3. IP packets at layer 1 are encapsulated into data link frame at layer 2 and encoded into bits at physical Layer 1. Router interfaces participate in processes associated with their encapsulation at layer 2. A router Ethernet interface, for example, takes part in the ARP process like other same LAN hosts. Router interfaces may vary, but Serial and FastEthernet interfaces are common. Static and Dynamic Routes Static routes are easily and manually configured. However, in large networks the manual operation can be quite cumbersome. Static routes have a default administrative distance of 1. If theres not a more specific match in the routing table, the default route, 0.0.0.0 network address and 0.0.0.0 subnet mask, is used to forward the packet to another router. Dynamic routing protocols require less administrative overhead. They do discovery of remote networks, maintaining up-to-date routing information, choosing the best path to destination networks and have ability to find a new best path if the current is no longer available or if there is a topology change. Static routing is still used nowadays, more often than not, in combination with dynamic routing. Conclusion As introduction of more industrial devices which have built-in Ethernet capabilities continues, networks keep becoming more complex and get crowded with signal traffic. This increases the necessity for Ethernet switches and routers with advanced technology which limits collisions, control bandwidth and have ability to craft virtual local area networks. Companies like Cisco, HP and IBM are racing to produce devices based on the new Energy Efficient Ethernet Standard (IEEE 802.3az). The announcement of CGR 2010 and CGS 2520 router and switch products by Cisco Systems recently designed to aid utility companies in supplying power to homes and businesses under the Smart grid project, a conglomeration of existing and technologies under development, hoped to ameliorate aging US power grid in the near future. As internet speeds get faster, through copper and fiber, switches and routers must possess features of high capacity and expandability. HOW THE INTERNET WORKS (incl. IPv4 and IPv6) Internet protocol suite It refers to a model architecture which divides methods into one layered system of protocols commonly known as TCP/IP, the two most important protocols in it. It is composed of the Link layer, Internet, Transport and Application layers. The link layer provides basic connectivity between computer networking hardware and associated interface-interface messaging management. The Internet layer facilitates interconnectivity between networks and has the Internet Protocol defining IPv4 and IPv6 used to locate hosts on the network. Transport layer provides a framework to convey data between hosts with the help of protocols like TCP and UDP. Application layer deals with application-based interaction between communicating Internet hosts on a process-to-process level. The Domain Name System (DNS) This is the whole network of programs and databases that cooperate to translate hostnames to IP addresses. Internet hostnames are composed of parts separated by dots. A domain is a collection of machines that share a common name suffix. Domains can also live inside other domains. Each domain is defined by an authoritative name server that knows the IP addresses of the other machines in the domain. The primary name server may have backups in case it goes down. The name-servers do not have to know the locations of all the machines in other domains including their own sub-domains, just the location of name-servers. Each top-level domain server knows where the name-servers for the domains directly beneath it are. Classful and classless routing IPv4 addresses were initially allocated based on classes A, B, C, D. Classful routing utilizes routing protocols which do not send subnet mask information if there is a sent out route update . All network devices must use a similar subnet mask e.g. RIPv1. In classless routing, the network portion of the address is determined by the network subnet mask, also known as the network prefix, or prefix length In Classless routing, subnet mask information is sent out in the routing updates. It allows VLSM (Variable Length Subnet Masking) e.g. RIP V2 EIGRP OSPF. RIP V1 has no Support for VLSM and doesnt support discontigious networks. RIP v2, however, supports VLSM networks and discontigious networks through routers compliant with Classless-Inter Domain Routing, which reduce size of routing tables. Governance The internet is a globally distributed network made up of many voluntary interconnected autonomous networks. It runs without a central governing body. Nevertheless, to maintain interoperability, all technical and policy features of the underlying central infrastructure and the primary name spaces, that is, domain names, IP addresses, application port number and many other parameters are administered by a body called Internet Corporation for Assigned Names and Numbers (ICANN) in California. World Wide Web and the internet These two terms are often used daily without much distinction, yet have different meanings. The internet is made up of hardware and software infrastructure that ensure availability of connectivity between computers. The World Wide Web or just the web is one of the services transferred through the internet. It is a pool of interconnected documents and many other resources interconnected by hyperlinks and URLs. Technical terms related to the internet include: URLs It stands for Uniform Resource Locator and is used to uniquely identify each of the billions of web pages across the world and help one guide others to them. Internet Backbone The first high speed Tier 1 backbone was created by the NFS in 1987. Backbones are typically fiber optic trunk lines with multiple fiber optic cables to increase the capacity. Bandwidth This is the transmission capability of the lines that convey the Internets electronic traffic where a larger bandwidth transfers more data at a time. Lack of bandwidth can inflict severe restrictions on the quick information delivery by the internet. Peering This is where multiple ISPs are linked at peering points or Internet exchange points (IXs), permitting routing of data across each network, without transmission charges on one another for the data which would otherwise have gone through a third upstream ISP, attracting charges from the upstream ISP. Web hosting This is a form of internet hosting service that lets individuals and organizations make their own websites reachable through the World Wide Web. Web hosting companies offer space on a server they either own or have leased for use by their clients and furthermore provide internet connectivity usually in a data center. IPv4 The Internet Protocol enables internetworking and fundamentally creates the internet itself. IP Version 4 (IPv4) is the preliminary version on the initial generation of todays internet and is still dominantly in use. It was aimed to address up to 4.3 billion (109) internet hosts. IPv4 addresses were initially allocated based on classes. In the original specification of IPv4 (RFC 791) released in 1981, the authors established the classes to provide three different sizes of networks for large, medium and small organizations. As a result, class A, B and C addresses were defined with a specific format for the high order bits, which are the left-most bits in a 32-bit address. The remaining addresses were reserved for multicasting and future uses. However, IPv4 addresses are being exhausted due to the explosive growth of the internet, and the exhaustion is estimated to enter its final stage around 2011. (Microsoft Corporation, 2009) IPv6 The exhaustion led to development of IPv6 around mid-1990s, which provides massively larger addressing abilities and much more efficient routing of traffic. Presently, IPv6 is in commercial deployment phase across the world and internet address registries (RIRs) have started to urge all resource managers to organize rapid implementation and conversion. IPv6 is not interoperable with IPv4 as it basically creates a parallel form of the internet that IPv4 software cannot directly access. Software upgrades or translator facilities are thus essential for each networking device that requires communication on the IPV6 internet. While most recent computer operating systems have by now converted to function with both versions, network infrastructures still lag behind in this development. (Teare Diane, 2006) Client-Server Architecture A computer operates software known as the client and it interacts with another known as the server found at a remote computer. The client is typically a browser such as Mozilla Firefox or Internet Explorer. The server interacts with the browser using a set of guidelines called protocols. These protocols aid in the correct transfer of data via requests from a browser as the server responds. The World Wide Web brings the many protocols available on the Internet together so one can use HTTP, Telnet, FTP, Email etc. on one platform, the web browser. Inside the HTML page the web designer embeds the server-side language code. This code is handed to the suitable interpreter which processes these guidelines and generates the ultimate HTML displayed by the browser. Internet security Cryptographic methods and protocols that have been developed for securing communications on the Internet ensure cyber security. Protocols including SSL and TLS for web traffic, PGP for email, and IPsec for the network layer security have been developed to secure internet communications. Firewalls are used to control access between networks. They consist of gateways and filters which vary from one firewall to another and screen network traffic, blocking that which is dangerous or malicious. Antiviruses are used to protect networks and devices from computer viruses, malware, Trojan horses, spyware, worms and botnets. Conclusion Since its conception in 1969, internet has evolved more than anything else to react positively to new requirements. With faster speeds now, internet is used in banking, gaming, advertising, social networking like Facebook and almost everything else. Shaping the future of internet, CSS3, Fonts as a Service such as Typekit that cater to web browsers that support the font-face rule already, and HTML5 are providing web designers the creative liberty that they have been craving for a long time. Yet new ideas and technologies bring new challenges. Many feel a clean slate approach is the one sure way of correctly addressing security, mobility and further challenges that have arose since 1969. Researchers believe its time to reconsider the Internets underlying architecture, a change that might mean getting to replace networking equipment and modifying computer software to channel future traffic over the existing pipes better. Within a decade, the National Science Foundation (NSF) funded GENI and European Union backed Future Internet Research and Experimentation (FIRE) research programs would be making a considerable change of the internet.

The Effect of Racism on the Self-Esteem of African Americans and the He

Throughout the past, scientists have attempted to explain the health disparity between African Americans and Whites. With the completion of the human genome project, it was shown that there is very little difference between different races on the genetic level. However, â€Å"African Americans are twice as likely to die from cardiovascular disease as their European counterpart,† the question that has arisen is where do these differences stem from (Harell, Floyd, Daniels and Bell). Recently, scientists have begun to believe that racism could possibly explain these differences (Belgrave &Allison, 2010). Racism has been an issue for African Americans since the early days of slavery. Everywhere they go, they face a possibility of being treated differently because of their race. Within the past fifty years, the racism that African Americans faced has dropped, however it is still prevalent. According to Belgrave and Allison, racism is defined as â€Å"the negative beliefs, actions, and emotions based on race† although there are different types of racism, this definition gives a generalization on what racism is. It seems as though racism is the cause of many of the health problems that are faced by African Americans. Whether it is because African Americans generally do not receive the same health service as Whites or because direct racism causes higher blood pressure, racism has a negative health effect on African Americans (Belgrave &Allison, 2010). Purpose The purpose of this experiment is to see whether racism has an effect on the self-esteem of African Americans and the health risks associated with racism, mainly high blood pressure. The independent variable is perception of racism and the dependent variables are the self... ...nd blood pressure. Racism is a problem facing many African Americans in the United States. It is affecting both their self-esteem and health. Until they are given the help they need or racism dissipates from society, they will always have these problems. References Belgrave, A.

The world is not really there

As though the quantum physicists would ever agree: There is world out here, and global warming portends its end. That’s the truth of it all, really, the world was never actually there, Speak the quantum physicists once again. But there is something here, Answer people like Al Gore who seem to notice things in the void. Indeed, they are positive that it is possible to manage the problem. They add: ‘The fact remains that the effects of global warming ‘Would be utterly disastrous if all those who are bumming ‘With the climate do not struggle to control anthropogenic greenhouse ‘Gas emissions. After all, human beings are partly, if not wholly responsible ‘For climate change. ’ So, someone from an LDC hears Al Gore in his Movie, An Inconvenient Truth. A bomb explodes as the bomber shows his Approval near an LDC beach. Al Gore continues, ‘Fortunately, it lies In their power to gradually reverse the effects of global warming. ’ So, what is global warming? There is no doubt about the fact that our world Has been warming up like a teenager in heat Trying to come up with ways to become fit for survival. Eleven out of the past twelve years, that is, the Bible Fighters’ time with the Qur’an fighters; in other words, 995 to 2006 have been ranked among the twelve â€Å"warmest years â€Å"Since 1850† (â€Å"Global Environmental Outlook 4: Environment for Development†). Humans did not keep systematic records of temperature Before 1850 (â€Å"Global Environmental Outlook 4†). How could they when they are still so helpless? How could you imagine them To keep systematic records of temperature before 1850? In any case, scientists are confident that there is something Terribly wrong with almost everything done by humans, including Their contribution to the fact that there has been a steady increase Of global surface temperature between 1995 and 2006. The evidence of global warming includes the shrinking of or fading away Of beautiful things like mountain glaciers in many parts of the world; Thawing of permafrost; the early breakup of lake as well as river ice; Lengthening of growing seasons (especially mid to high latitude); Shifting of animal, insect and plant ranges; early flowering of trees; Early emergence of insects and egg laying of birds; Changes in ocean currents as well as patterns of precipitation; And the increasing lifetimes and intensities of tropical storms In several regions of the globe (â€Å"Climate Change 2007: The Physical Science Basics†). As though we care! Ha! The United Nations, spreading news around the world, Stories they refer to as research For the minds and the eyes of the rich Alone, saying things like the following, as though anybody cares Except to say Ooh and Aah at these shocking tales: ‘Seeing that the poorest people of the world are rather dependent ‘On a hospitable as well as stable climate – they’re dependent ‘As always – for their crop growing needs as well as gathering ‘Of natural resources – before they are snatched or stolen through invasion – ‘It is vital to understand climate change before we try to manage it – Pretending that we are able to manage everything, we will manage it’ (â€Å"Global Environmental Outlook 4†)! The United Nations, our supreme council for research and no practical work Apart from research, adds: ‘Poor people are reliant on the monsoon seasons – and us – ‘As you k now, climate change is about to turn their lives around. ‘Moreover, it is the poorest people of the world around ‘Whom all our concerns rest at this time because these people ‘Are most vulnerable to the destruction caused by natural disasters. ‘The Asian tsunami provides evidence of this phenomenon – ‘As do bombs because they heat up things, including our minds, as no one Disagrees. Increase in drought frequency in Africa is another reason ‘Why policymakers around the globe must consider decisions ‘That would have a long-term impact on humanity – once they find ‘The time to consider such decisions, of course; they must then bind ‘Governments in contracts to reduce gas emissions knowing their contracts ‘Exist only on papers with paper pins neatly making stacks of their contracts’ (â€Å"Global Environmental Outlook 4†). The United Nations expresses deep concern in its voice as it continues: ‘Other examples of destruction caused by climate change To the poor communities in particular – who else? – include ‘The effects of Katrina in the United States and that long, crude ‘Heat wave that was experienced by Europeans in 2003. à ¢â‚¬ËœAs these examples reveal, poor people in rich societies are also vulnerable to the devastating ‘Effects of global warming – the rich people need not worry’ (â€Å"Global Environmental Outlook 4†)! In war-torn Iraq A man is sipping tea in war-torn Iraq. Flimsy pages of his newspaper, Iraq Today, fly here and there as they stay put Nevertheless in his lap; and input From the pages enters his mind as slowly As memories of the bony lass slowly Leave his mind – memories that had tormented Him ever since the Iraq War began. ‘Kid, ‘She is gone, she left with the soldiers of the United States,’ The landlord of her flat had informed him. So now the man hates Everything he hears from the country where the bony lass resides. Still, out of necessity, he listens to those pages, presides Over them as though he would do something about the news on those pages; If only pretend he would do something about the news on those pages. As his tea cools under those fans that don’t really help him feel cooler In the head where suppressed anger and worry due to the vast dollar Country’s actions stay, he chances upon a piece of news that suddenly Interests him although he did not really care whether it was hot or cold. ‘Global warming,’ says the piece. ‘A publication of the United Nations ‘Environment Programme, Global Environmental Outlook 4, states ‘That the effects of global warming would vary across the globe. ‘According to the report:’ While the Earth’s climate has varied throughout the prehistoric ages, the last few decades have witnessed a global climate disruption that is unprecedented over the recent millennia, a period of relative climatic stability during which civilization emerged. Some regions, particularly the Arctic, will be more affected by climate change than others closer to the equator. In many regions, the agricultural sector will be particularly affected. The combination of high temperatures and decreased soil moisture projected for parts of Africa will be particularly hard to adapt to. (â€Å"Global Environmental Outlook 4†) ‘I think this is what the Prophet (Peace be upon him) had told us about,’ The man in Iraq reflects on the warning of the United Nations. He continues Reading the news report: ‘Global Environmental Outlook 4 ‘Also describes the main responsibility that human beings must assume For global warming: that, in fact, humans have placed great pressure on the ‘Climate system with increasing anthropogenic greenhouse gas emissions. ‘The greenhouse gas that is mainly responsible for climate change appears ‘To be carbon dioxide, primarily originating from the consumption of ‘Fossil fuels (â€Å"Global Environmental Outlook 4†). The UNEP report ‘Further describes the environmental damage caused by humans ‘While they were ignorant of the dangers of global warming: Since the dawn of the industrial age, the concentrations of these gases have been steadily increasing in the atmosphere. The unprecedented recent rise has resulted in a current level of 380 parts per million, much higher than the pre-industrial (18th century) level of 280 ppm. Since 1987, annual global emissions of carbon dioxide from fossil fuel combustion have risen by about one-third, and the present per capita emissions clearly illustrate large differences among regions. (â€Å"Global Environmental Outlook 4†) So now he understands, the man sipping tea: ‘Everything in this report describes the fee ‘For occupying this world. Moreover, it is as the Prophet ‘(Peace be upon him) had described. It is the call of the Prophet For us to mend our ways once and for all. God is going to take account. ‘But who is listening? Does anybody care? ’ The man folds the account On global warming on one of the flying sheets of newspaper, Iraq Today. He decides to return home when he gets an idea, straight out of Iraq Today. He thinks: ‘Overly excited about their achievements during ‘And after the golden Industrial Age, human beings did not realize ‘That materialism and greed could even be responsible for ending ‘Their existence on Earth in the near future. Indeed, if climate change ‘Is not managed through effective global policies at present, huge natural Disasters may very well finish off all life on our planet. ‘As it is, global warming is accompanied by spells of really high temperatures ‘That are known to destroy life through heat stress in addition to air pollution. ‘In June 2003, Europe experienced such a spell. It raised temperatures ‘Twenty to thirty percent higher than the average temperatures during summer. ‘What is more, the spell covered a huge portion of the European continent, ‘From Germany to Italy, and from the north of Spain to Czech Republic. ‘With social as well as economic impacts, besides its environmental impacts, The heat wave presented heavy losses to the European continent. ‘In point of fact, thirty thousand European people lost their lives during June 2003. ‘Forestry and agricultural production were impaired; forests were burned; ‘Crop cycles we re disrupted; nuclear reactors cooled by water from rivers ‘Had to be closed; demand for electricity could not be met; ‘And the stability of rocks was affected’ (â€Å"Impacts of Summer 2003 Heat Wave in Europe†). ‘Once they know what we go through each hour, each day ‘They would surely become one of us, one of clay ‘People. ’ As he ends reflecting on climate change, he Remembers another similarity between man and man: ‘Hadn’t God said, We made man out of clay? ’ He tries to figure out in his mind whether fire can damage clay, But then another worry enters his mind: ‘Do the industrialists ‘Also know, We made man out of clay? ’ In Europe The man in Iraq was happy to know that Europe had experienced Significant development during the Industrial Age, Although it did not have any power over the heat wave of 2003. A construction worker in Germany, on the other hand, Understood it this way: he thought: ‘It is evident that the European Union ‘Would now play an important role in reducing greenhouse gas emissions. The heat wave of 2003 served as a warning for the entire continent ‘To begin taking serious action against greenhouse gas emissions, ‘While enjoying the fruits of the Industrial Age even in the twenty first century’ (â€Å"Impacts of Summer 2003 Heat Wave†). Even though he was optimistic, the construction worker Believed that he knew that politicians only tell lies to the People, the voice of the people is never heard, and democracy Is a sham. As he thought about politicians suffering from all sorts Of amnesias, another fact was brought to mind simultaneously; The construction worker felt delighted in the misery of others When he remembered he had read somewhere that As bad as the European heat wave of 2003 was, There is no way for it to compete with the rising average Temperatures in the Arctic. In fact, temperatures in the Arctic Are â€Å"rising almost twice as rapidly as in the rest of the world† (â€Å"Global Environmental Outlook 4†). † Sea ice and glaciers in the Arctic are presently melting, While the permafrost temperatures are rising. In Siberia and Alaska, permafrost is also melting. This is expected to release methane into the Earth’s atmosphere From the frozen hydrates. Scientists are aware that fifty Million years back, a large amount of methane was released Into the Earth’s atmosphere. Temperatures around that time Must have risen approximately five to seven Celsius. Additionally, scientists have determined that it took approximately One hundred and forty thousand years for the atmosphere To return to its normal state after the initial release of methane (â€Å"Global Environmental Outlook 4†). ‘Perhaps, therefore’ – reflected the construction worker – ‘The effects of global warming would remain with us ‘For a very long period of time. Our future generations ‘Would have to suffer because of the excessive greenhouse Gas emissions that our generation has been held responsible for. ‘Other effects of global warming include increased changes ‘In precipitation around the world. While wet regions are experiencing ‘More rain, the dry areas of our world are turning more arid than before. ‘In addition, regi ons like Africa with â€Å"the lowest contribution to anthropogenic greenhouse gas ‘Emissions† are projected to suffer most due to these changes’ (â€Å"Global Environmental Outlook 4†). ‘As a matter of fact, water scarcity is projected to become a dangerous ‘Problem for the African people in the days to come (â€Å"Global Environmental Outlook 4†). Global warming is also increasing â€Å"intense tropical cyclone activity,† ‘Especially in the North Atlantic (â€Å"Global Environmental Outlook 4†). ‘This has been going on since 1970, and is definitely associated ‘With increases in the surface temperatures of tropical seas. ‘Furthermore, there is evidence of increased tropical cyclone activity ‘In certain regions of the world where it is difficult to gather high quality data. ‘In any case, over the past thirty five years the number of Class 4 and 5 ‘High intense storms has almost doubled. These storms are now occurring ‘In virtually all ocean basins. Of a certainty, our world would warm up Even more because of this activity in the deep’ (â€Å"Global Environmental Outlook 4†). As the construction reflected on the meaning of global warming For everybody in the world, the only person he thought was Insulated from its disastrous effects was himself. His family, too, Would be saved, he thought, smirking in his mind’s eye when those miserable two – Arctic and Africa – were remembered. He had to earn his dail y Bread, after all. It did not really concern him that the people Of Africa suffered. He believed that the politicians with free Cups of coffee and bowls of rice available to them should do All the thinking for the poor people of the world. He was lucky To be German, that’s all. What concerned him about global warming was this: Indeed, there exist a number of paths for us to take to help Ourselves and our fellow beings survive on the planet. As an example, with the awareness that our buildings consume Almost thirty to forty percent of energy in our world – Another UNEP report, Buildings and Climate Change: Status, Challenges and Opportunities, advises governments Around the world to put policies into place for the construction Of environmentally friendly or green buildings that would not Exacerbate the effects of global warming. There are a variety Of choices available to modern man to use energy more efficiently than before (â€Å"Buildings and Climate Change†). ‘Would Herr Braun consider the alternatives? ’ – he asked Himself. After all, he was only a servant. Had he asked Herr Braun, would the latter have answered his loyal Construction worker? Maybe, maybe not. The royal Herr Braun was unreachable most of the time. But the construction worker’s fifty-seven year old wife Should be able to guess and inform him. She was good At divining things. She would know about global warming.

Concert Review Essay

The rhythm, which was continuously steady seemed to get faster like a heart beat by the climax of the song. It was also at this point that the dynamics of the song were increasingly getting louder until all instruments met at the top with a bang and then changed the dynamics again to a moderate level until the song concluded. â€Å"Waltz for Debby†, written by Bill Evans and arranged by Don Sebesky, was a consonant, slow-beat waltz. The texture of this piece remained the same through its entirety and the 1,2,3 pattern was also very noticeably throughout the piece as well. The saxophone, trumpet and electric guitar took turns at the melody and did so through this performance in the form of solos. The dynamics throughout this song were soft and then increased to a moderate level before a decrescendo to a softer level once again. The ensemble did a fabulous job of keeping with the beat. â€Å"Ancient Memories†, by Fred Hamilton and arranged by Paul Ferguson, was played the night of the concert by guest trumpeter, Darryl White. Mr. White played this song because it is the title track on his 1999 album, also called â€Å"Ancient Memories†. Mr. White is a professor of trumpet at the University of Nebraska. This piece began by having very dissonant tones within the harmony with the introduction of a piano and drums. The song then changed into a more consonant harmony, which remained throughout the rest of the song. The texture of this song was polyphonic between the trumpet and the piano. The melody of this song was bright and happy in some places within the song and more cool and relaxing in other parts as the tempo changed and the notes of the trumpet were held for emphasis. There were many dynamics used within this song. The song began with a crescendo from very soft to very loud and then remained in this pattern until the end when the pattern was reversed. â€Å"Fly Me to the Moon† was for me a song of romance from the time the first note began. The song was passionate and sexy and displayed dialogue without using any words. The ensemble played this piece with steadiness and the solo by Cassi Lee provided the extended dialogue that sounded like dancing and twirling in the moonlight. This song reminded me of â€Å"My Heart Will Go On† in that the instrumental nature of it tells a story, just as much as when Celine Dion is singing the lyrics. I found listening to this song a worthwhile experience and it was a fantastic beginning to the jazz concert in that it was familiar to the audience. â€Å"Waltz for Debby’ made me wonder who Debby was and why someone would write such an old-sounding song for someone they loved. The song was very pretty, but it was of a different genre than that of the other pieces within the concert. It is honestly hard for me to recommend this song to anyone, for I thought it was dull and lacked the depth of the other songs throughout the evening. â€Å"Ancient Memories† was a beautiful piece. I am not sure what I enjoyed more, the fact that Mr. White played with such passion and made the song his own life force or that this piece reminded me of my childhood. This piece reminded me of something Bill Cosby would have on the Cosby Show in one of the jazz clubs. The song was fun and although the song had a lot of repetition, I loved listening to the changes over and over again. The Jazz Ensemble concert at Tarleton was an enjoyable evening full of great music and intellectually stimulating experiences of music that I would not have listened to if not for this assignment. Diversification is an important lesson to learn when viewing music because all music has roots from another genre and recognizing this makes you more diversified as an individual.
