Enhancing Cyber Situational awareness through Active Defence Research Paper
Enhancing Cyber Situational awareness through Active Defence - Research Paper Example They include: i. Visualization of Situation Awareness data/ information ii. Metrics iii. Dynamic Risk Assessment for Mission Assurance However, Cyber Situation Awareness is still considered a new field of research that made its mark with Denning’s (1987, 2002) pioneering work on using expert systems to detect computer attacks in 1987, followed by a plethora of experiments thereafter. The early stage of experiments shaped the concept of tactical fusion, which was proposed by the JDL (Joint Director’s Laboratory) model in 1992. This model contains five functional levels such as 0, 1, 2, 3, and 4. It was published by Hall, and Llinas (1997). It focused solely on data management to prevent cyber attacks. In it, most of the tasks are concentrated on level 0, 1, and 4. Tadda finds JDL model as a bottom-up, data driven model (Figure 3). The significance of JDL model lies in the fact that it highlights the significance of algorithmic techniques towards supporting situation awar eness (Salerno, Hinman, & Boulware 2005). Figure 3: Tactical Fusion/JDL Model [Adapted from (Tadd 2008)] Explanation From a simple point of view, SA refers to the knowledge about ongoing events in the cyber environments. According to Ensley (2000: 3), SA defines three essential drivers which include perception, comprehension, and projection. As per Ensley, perceptions of cues (which he refers to as Level 1 SA) are fundamental, since in the absence of basic perception of important information the chance of wrongly visualizing the situation drastically increases. In support of this argument she cites a finding that showed 76% of SA errors of the pilots emanated from lack of perception of the required information (Jones & Ensley 1996). Comprehension on the other hand, refers to an outcome of how people interpret, associate, store, and retain information, and thus makes its place in SA process as Level 2 SA in Ensley’s (1995c). The Level 3 SA, i.e., Projection helps operators to perform at the highest level of SA, since it enables the operators to forecast on situation events and its dynamics, Ensley (2000). Ensley further explains that SA is all about â€Å"knowing what is going on,†while from a formal point of view it is all about â€Å"the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning and the projection of their status in the near future†(Ensley 1995b: 36). In a nutshell, Ensley consolidated the theoretical perspective of SA by adding human factors in it, thereby opening a new horizon of developments towards achieving quality SA (Wickes 2008: 397). Endorsement of the above view from a host of researchers (Ensley 1993, 1994; Ensley & Rodgers 1994; Ensley & Robertson 1996; and Endsley et al. 1998) highlighted the temporal aspects of time, as the above view showed that both perception of time and temporal dynamics associated with events play crucial roles in the formulatio n of SA, and a critical part of SA involves understanding of the amount of time available in the occurrence of an event or in the course of an action. Such developments helped researchers to underpin time as an integral part of Level 2

Biological Psychology Essay
Abstract Psychology has its own biological boundaries. This is in the form of biological psychology or behavioral neuroscience. The main aim of this branch in psychology is to have a clearer picture of the relationship of the mind and body, and mind and brain. It tries to link the brain functions to the different mental processes and behaviors. This type of psychology investigates man’s physiological phenomena such as memory and emotions. Biological Psychology Human beings are more then a collection of systems, more than a collection of organs and more than a collection of cells. The human body is complex. It is an operating organism which functions as a whole. The human body involves a great deal of variety of processes. By examining the parts, it does not mean that one can understand the whole organism (Arnold, 1999). Biological psychology is the field of psychology which main endeavor was to link the different brain functions to different mental processes and behaviors. Psychologists in this subdiscipline of psychology are often interested in relating biological variables to psychological or behavioral variables. It deals with biological processes and behaviors that are shared with mammalian animals. This is because biological psychologists utilize animals in their experiments. Some of these processes are sensation, perception, motivation, learning memory and control of motor movements (â€Å"Biological Psychology†).            The history of Biological psychology emerged from various philosophical views in the 18th and 19th century. However, its study started much earlier. It dates back to Avicenna, a Persian psychologist and physician. He recognized physiological psychology in the treatment of illnesses involving emotions. Avicenna also gave some psychological explanations on somatic illnesses. He believed that humidity inside the brain can cause mood disorders. Humidity is brought by the change with the amount of breath. Another is that happiness increases the breath so it contributes to the brain’s moisture. But then, too much moisture can make the brain loss control thus having mental disorders (â€Å"The Mind-Brain Problem†).            The philosophical history of Biological Psychology surfaced from philosophers like Rene Descartes. He believed that the pineal gland was the point of contact between the mind and body. He also proposed a theory that pneumatics or fluid power of bodily fluids is connected to reflexes and motor behavior (â€Å"The Mind- Brain Problem†).            Another philosopher who contributed to Biological psychology is William James.  He is the one who argued that in the study of psychology there should also be consideration to the understanding of Biology. He also stressed that the functions of the brain must be included in the study of psychology. The connection between mind and brain became progressively clearer in the nineteenth century. In this century, the doctors started observing patients who suffered from head injuries. The patients usually exhibited alterations in language and memory and some variation in their personalities. One patient is a refined businessman and a loving father became a vulgar person who lacks in affection for his loved ones after a sever blow in the head. These observations is lead researchers to experiment by producing surgical lesions in animals in different regions of the brain to observe what effects these lesions have on behavior (Westen, 1999). Since its origin, one of the major issues faced by biological psychologists was localization of functions. This entails knowing which different parts of the brain control different aspects of functioning. In 1836, a physician named Marc Dax, noted that lesions on the left side of the brain were associated with aphasia or language disorder. Because of this discovery, many other discoveries linking the left hemisphere of the brain with language function appeared (Westen, 1999). These other discoveries led to the finding of Broca’s and Wernicke’s areas. Broca’s aphasia involves difficulty in production of speech, whereas Wernicke’s aphasia involves difficulty in comprehending language (Westen, 1999).            The clinical assumption of Biological psychology is that organisms share similar biological processes and behaviors. Some of the other disciplines in psychology greatly related with biological psychology are comparative psychology, evolutionary psychology, neuropsychology, clinical psychology, cognitive psychology and experimental psychology (Westen, 1999).            Comparative psychology is the study of behavior and mental processes of animals other than human beings (Westen, 1999). Biological psychologists use animals in their experiments. They compare the results done on these animals to human processes and behaviors. Evolutionary psychology, on the other hand, deals with the explanation of mental and psychological traits and how they evolved to adapt to different stimuli. Neuropsychology is an interdisciplinary field of psychology and neuroscience that aims to explain how the structure and function of the brain relate to certain psychological behaviors (â€Å"Evolutionary Psychology†).            Other fields of psychology related with biological psychology such as clinical psychology, cognitive psychology, and experimental psychology are connected with biological psychology because these fields aim to link the physiological processes with different mental processes. Clinical psychology focuses on the nature and treatment of physiological processes that lead to emotional distress. Cognitive psychology examines the nature of thought, memory and language. And, experimental psychology examines mental processes in human and other animals (Westen, 1999). Some of the noted modern biological psychologists are Nikolaas Tinbergen, Karl von Frisch, Eric Kandel and Arvid Carlsson. Nikolaas Tinbergen is a Dutch ornithologist who won the Nobel Prize for Physiology in 1973. His contribution is the organization and elicitation of individual and social behaviour patterns in animals. Karl von Frisch is an Austrian ethologist who won the same award with Tinbergen. He studied the senses of bees and identified they methods of communication(â€Å"Nobel Prize in Physiology/ Medicine 1973†)..Eric Kandel is a neuroscientist whose contribution is the analysis of biochemical changes in neurons assiciated with learning and memory storage. Arvid Carlsson is a neuroscientist most noted for his on the neurotransmitter dopmaine and Parkinson’s disease (â€Å"The Nobel Prize in Physiology/ Medicine 2000†).  Reference Arnold, T. (1999).

Jerry Maguire-Case Study
LED 605 Negotiations*, Bargaining and Conflict Resolution*: Jerry Maguire Case Study by Hana Jurcovicova For our case study assignment we watched a short part from Jerry Maguire movie. In this movie Jerry Maguire is a sport agent. This kind of job was always his dream. But he is not happy in his job. He hates himself and what he became. He hates the company that was all about money. He learned when he first started, that the job of a sports agent is mostly about personal relationship, caring for people doing business with and meeting their needs. He writes a new mission statement for his company, for the future of it. He wants to make it a company he would like to work for. He thinks that the most important thing is to have fewer clients, which they can take better care of. Fewer clients mean less money for the company which is oriented mostly in making a lot of money. He writes a little book about this mission statement about what we think but never say loud and put it in every mailbox of every employee. The next day when everybody reads it or is still reading, people are clapping to Jerry Maguire even though they know almost for sure he was going to be fired for that. Jerry Maguire is fired later on in the movie. He is fired for sharing his personal opinion and writing about it. It looks like he wants to set people against the company and the way it operates right now. Moreover he did not discuss this mission statement change with any of the members of the board or CEO. Nobody gave him the permission to release his new mission statement to public.

The Case Of Margaret. Margaret - 788 Words
The Case of Margaret Margaret is a forty-year-old woman, whose husband left her for a younger woman. Margaret has experienced symptoms of shock, rage, and weeping spells. She has been isolating herself in bed because she doesn’t want to deal with anyone or anything. Along with her depressed mood, she has been consuming alcohol in a considerable amount. Margaret’s business has been suffering and she feels like a â€Å"total failure†.

Explication Of John Donne s Holy Sonnet 14 - 933 Words
Explication of John Donne’s holy sonnet 14 The beauty of John Donne’s holy sonnet 14 is in its language. John Donne is an interesting character who uses metaphors anyhow he pleases and finds a way to make it work. The beginning of the poem depicts a man hopeless without God’s help, a man trying to change his ways but finds no success and asks God to change in a way I find quite terrifying. The use of violent and erotic language (i.e Batter, Force, Labor, Captive; and erotic words: i.e ravish, love, knot etc) set the tone of the sonnet, and it remains constant all through. Before diving into the content of the poem, we look at the form of the poem. This poem has a Petrarchan form, and an Elizabethan structure. I know this because it has 14 lines, the rhymes, and the ending couplet. The poem rhymes like: ABBAABBA – CDCDEE. Also we look at the iambic pentameter. The beginning of the poem looked like it would be in iambic pentameter: Batter my heart, We can see here the poem starts with â€Å"Batter†w hich has a stressed syllable, followed by â€Å"My†which is unstressed, and â€Å"Heart†which is stressed, but then, that’s followed by â€Å"three-personed God†which breaks the iambic pentameter. The same can be seen on Line two. I think the essence of starting a poem this way was to start with an aggressive tone in order to prepare the reader for the story ahead. This easy begins with the writer speaking to a â€Å"three-personed God†(I believe that means the father, son, and holy spirit). He uses
