Terminologies in the ICN architecture

Terminologies in the ICN architecture The research on the Information-centric Networking initiated with the need to replace the current inefficient architecture to a promising model that could satisfy future network necessities [1]. The several projects on this research are differentiated in the operations of the key building blocks common to most projects [4]. Named Data Objects (NDOs)   Ã‚   Every content on the internet ranging from a web page, documents to media files is referred to as objects (NDOs) which are independent of location, storing and retrieval methods [4]. NDO and its name is the identity of the information on the internet which can be copied, requested and supplied. NDOs can also hold representative data about the information held by the object [4]. Naming Every NDO in ICN is to be assigned a unique name, and should also associate an integrity check with the information it holds to ensure reliability [4]. They are always location-independent and range from structured to flat and may be human interpretable or not [1].There are two different naming schemes hierarchical and flat namespaces. The hierarchical scheme has a structure to the name rooting to publisher prefix which may also be human-readable in some cases, enabling aggregation and scalability in routing mechanisms [4]. The flat namespaces use the hash of the content with the objects name for direct binding and embed public key and hash of the content for indirect binding [4]. The publisher field in flat names facilitates some level of route aggregation even if it is a non-hierarchical scheme [4]. The difference in the design trade-off affects routing and security mechanism [4]. Security This feature is correlated to the naming scheme adopted by the approach. Human-readable names require external trust agent for verification, while flat names support self-certification and validation [1]. Hierarchical naming is considered disadvantageous as it relies on public key infrastructure (PKI) [4]. Application Programming Interface (API) The ICN API is related to the operation of asking and getting the NDOs. There are different terms denoted for the operation that varies which will be discussed during respective approach. The source provides NDOs by publishing it to the network. The user requests the network to get the NDOs by subscribing to it. As per approach, the publish/subscribe operation may be synchronous or asynchronous, while some support location preferences [4]. Name Resolution, Routing, and Forwarding of the Content The name of NDOs is resolved by matching the information name to the source provider [1]. Resolution may be direct or indirect routes to the source/s. The operation is carried out by Name Resolution Service (NRS) in the routing infrastructure which stores pointers to the storage locations containing the object names [4]. The routing and forwarding of the objects are carried out in multiple steps which involve routing the request to the direct source or to the responsible NRS, translation of object name to source/s addresses if indirect, forwarding the request to the source and fulfilling the requested data back to the client [4]. The content routing may be coupled or de-coupled to the name resolution process. Coupled routing backtraces the request message path from the client and follows the same for delivering content. De-coupled routing uses different routes which can be generated by an independent routing module that provides a deliverable route to the source [1]. Caching Caching is application-independent and may be done at every node in the ICN infrastructure [4]. ICN supports on-path caching and off-path caching. On-path caching is caching the information along the path of NDO request message while Off-path caching is exploiting the information cached outside that path [1]. Off-path caching can be supported in both coupled and de-coupled routing mechanisms by routing systems or NRS respectively [1]. Mobility ICN facilitates content request process from user end as the request can be re-initiated after the handoff while providing mobility to the source is difficult in both coupled and de-coupled approach as it burdens the system with additional updates [1]. By caching and replicating content at multiples nodes closer to the mobile subscriber, the ICN infrastructure saves costs and time by bypassing possible congestion [2].

Marriage in ancient Rome Essay -- essays research papers

The Roman institution of marriage has been lauded as being the first purely humanistic law of marriage, one that is based on the idea of marriage being a free and freely dissolvable union of two equal partners for life. (Schulz, 1951;103) This is quite a simplistic view, as there were many differing forms of marriage in Rome, from the arranged marriages of the elite to the unions of slaves and soldiers. As we shall see, the Romans' actual expectations of married life and the gains they envisioned they would receive from the experience depended greatly on their age, sex and social status. Unlike our contemporary society, no specific civil ceremony was required for the creation of a marriage; only mutual agreement and the fact that the couple must regard each other as husband and wife accordingly. (Gardner,1986;47) Although not a legal necessity, some weddings, usually the first marriage of elite couples was accompanied by much revelry and song, as featured in one of Catullus' poems. It describes the celebration of the marriage with dancing, singing and the brandishing of torches. Ribald jokes are shouted at the bride and nuts are scattered as she makes her way towards her husband's house. The groom arrives before the bride so that he can personally invite her to come and share his home. Now married, what does the couple expect to gain from the experience? The young bride is most probably in her early teens, as is the girl described in Catullus' poem with the words, "Young boy, release the little girl's small smooth arm". After marriage she will be transformed from a "little girl" into a respected wife. Elsewhere Catullus assures his readers that young daughters are unloved by their parents until they are married. "If, when she is ripe for marriage, she enters into wedlock, she is ever dearer to her husband and less hateful to her parents†¦" (Catullus, Poems 62.57-65) If we are to take this at face value, then marriage for young girls gains them the affection of their parents. A similar sentiment is found in the funeral eulogy from Rome for a woman named Murdia. It speaks of her dealing with her arranged marriage with obedience and propriety and "as a bride to become more beloved because of her merits†¦".

He wanders lovesick to her room only to discover she is not there. It is safe to say that one of the gains from marriage for both partners was sexual satisfaction, even if certain men did look outside the marriage bed occasionally.

Psychology †Pretty Little Liars Style Essay

Psychology The science of behavior and mental processes Nature vs. Nurture The controversy over the impact which genes and experiences have on psychological behaviors. Just like in the Bad Seed (performed at Rosewood High,) psychologists wonder if evil is something inherited or learned. Basic Research Science whose main goal is to increase the scientific knowledge base. Applied Research Scientific studies which aim to solve practical problems, like forensics being used to determine if the Liars’ evidence is real. Clinical Psychology A branch of Psychology which studies psychological disorders. Mona would have to have seen a clinical psychologist†¦ that chick cray. Psychiatry A branch of medicine dealing with psychological disorders, with physicians who often give medicine to their patients. Empiricism The concept that knowledge comes from experience via the senses, while science comes from observation and experimentation. Jenna had lost the sense of sight, so in a strange, empirical sense, she could be less knowledgeable than the Liars†¦ if not, she certainly is more crazy. Hindsight Bias The tendency to believe that after a known outcome a person had known it all along. Reminiscent of people claiming they had known Toby is part of the A team†¦ It can’t be true!! False Consensus Effect The tendency to overestimate the extent to which others share our beliefs and behaviors. Similar to how Spencer completely opened up to Toby, assuming that there was no way he was involved with A. Illusory Correlation Surely connected to the phrase â€Å"correlation is not causation,† this is the perception of a relationship where none exists. Similar to how Noel kept imagining a relationship between himself and Aria. Independent Variable The experimental factor which is being manipulated and whose effect is being studied†¦ ust like how A manipulates the Liars to watch them crack. Dependent Variable The experimental factor which is being measured. A manipulates the Liars to see how far she can get them to crack. Evolutionary Approach The study of psychology using the principles of natural selection. A seems to follow Darwin’s theories, eliminating the weakest of the NAT club one by one. Biological Approach The study of Psychology linking psychological progresses and biology, such as genetics. This is similar to A’s belief that Aria would have an affair with Ezra simply because her father had also had a student-teacher relationship. Behavior Genetics Approach A theory which determines how our environment influences our individual differences. The Liars all had secrets similar to the ones their parents had kept, be it lying, cheating, or stealing. Psychoanalytic Approach Studies using Freud’s theories on how the unconscious drives our behavior. Humanistic Approach Emphasize the growth potential of healthy people†¦. such as the ever beautiful Keegan Allen. Structuralism An early school of psychology which used introspection to explore the structure of the human mind. Similar to how Dr. Sullivan asked Hanna to think back about her relationship with Alison to help her move past her death. Functionalism A school of psychology which focused on how mental process allow an organism to adapt, survive, and flourish. In the movie Psycho (scenes from which were replicated in the episode â€Å"unmAsked†) Bates had become his mother in order to cope with his life and adapt to his condition. Human Factors Psychology The study of how people and machines interact. For instance, how the Liars are so reliant on their cellphones, even though that’s what brings them misery. Bottoms-Up Processing Perception, or analysis of sensory information, which begins with the sense receptor and works up to the brains integration of sensory information. Aria and Emily had first seen Caleb talking on the phone, and after listening to him talk, they then interpreted his conversation to mean that he was lying to Hanna. Top-Down Processing A form of higher level mental process which constructs perceptions based on experience and expectation, more similar to how Spencer learns information. Sensory Adaptation Diminished sensitivity in consequence of constant stimulation. Similar to Paige’s concern over the fact that Emily has become so used to â€Å"A† that she no longer realizes the danger she constantly is in. Associative Learning Learning that two events occur together, typically stimuli and a consequence. Similar to the Liars becoming convinced that every ad thing that happens to them is linked to â€Å"A†. Behaviorism The view that Psychology should be an objective science that studies behavior without reference to mental processes. Many people had believed that Mona was not truly sick because of her mental state, but merely because of her objective behavior. Classical Conditioning A learning style where an organism associates stimuli. Pavlov’s study of dogs salivating was a large factor. The Liars had received texts from â€Å"A† and got scared, now simply hearing their phone go off is enough to scare them. Unconditioned Response The unlearned response in classical conditioning, in this case, the fear behind the texts. Unconditioned Stimulus The stimulus which naturally triggers a response. In this case, â€Å"A†. Conditioned Response The learned response to a previously neutral stimulus. The Liars learned to fear their cellphones. Stimulus An irrelevant stimulus which eventually becomes a stimulus in classical conditioning. In this case the Liars’ cell phones. Conditioned Generalization The tendency once a response is conditioned, for similar stimuli to issue the same response. For instance, if the Liars were to then fear their computers and other technology as well. Acquisition The initial stage in classical conditioning where the stimulus first elicits a response. Like when the Liars first jumped after hearing Aria’s cell phone ring at Alison’s funeral. Extinction The diminishing of a conditioned response, such as after Mona was found to be â€Å"A. † Operant Conditioning A learning style where behavior is strengthened following reinforcement or diminished by punishment. Like â€Å"A† terrorizing the Liars to punish them for how they acted around Alison. Law of Effect Thordike’s principles that behavior followed by favorable consequences become more likely and that behaviors followed by unfavorable consequences become less likely. For instance, Byron stopped having affairs after Alison blackmailed him in punishment for his actions. Operant Chamber The â€Å"Skinner Box† used to teach rats to hit a bar in order to obtain food or water. Shaping An operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of a desired goal, like guiding mice to a specific area of a cage. â€Å"A† does this to lure Spencer into the fun house at the founders day festival. Fixed-Interval Schedule In operant conditioning, a schedule of reinforcement that reinforces a response only after a specific amount of time. Similar to having a paycheck and a specified pay day, which Ashley did have, but it just didn’t seem to be enough. Variable-Ratio Schedule A schedule of reinforcement that reinforces a response at an unpredictable amount of responses. Similar to Lucas and his gambling problem. Latent Learning Subject matter which is learned but not demonstrated, such as Mona pretending to be less intelligent then she really is. Overjustification Act When you reward someone for doing something they already like to do, such as Emily winning anchor. They won’t see it as a reward, but that doesn’t mean former psychopaths like Paige won’t see it that way. Neuron A nerve cell, the basic building block of the nervous system. Just like how Alison was the main building block of the Liars. Dendrites The branching extensions of a neuron that receive impulses, such as the Liars receiving information from A. Axon The extension of a neuron through which messages are sent to other neurons or to muscles or glands. Toby was an extension of Spencer who sent out messages as A. Myelin Sheath A layer of tissue that encases neurons. It enables faster transmission of neural impulses. The Liars’ families and their secrets protect the Liars, yet A uses them to get across their message more clearly. Threshold The level of stimulation required to trigger a neural response. After finding Toby was A, Spencer’s threshold for tolerating Mona sunk to an all-time low. Acetylcholine A neurotransmitter that triggers muscle contraction. Such as the neurotransmitter that makes Pretty Little Liars fans twitch every time Toby comes on screen. Central Nervous System The brain and the spinal cord, which are linked to survival†¦ something Alison was terrible at. Autonomic Nervous System The part of the peripheral nervous system that controls the internal organs. Such as the gorgeous boys of the show who control the hearts of the Liars. Sympathetic Nervous System The part of the autonomic nervous system that arouses the body. Parasympathetic Nervous System The part of the autonomic nervous system which calms the body. Medulla The area of the brain that controls breathing and heart beats. Sensation The process of sensory receptors receiving stimulant energies from the environment. This can be analogous with the Liars gaining clues to A’s identity. Perception The process of interpreting sensory information to recognize objects and events. Analogous with interpreting clues to determine who A is. Psychophysics The study of the relationship between physical characteristics of stimuli, such as intensity, and the psychological experience of them. Absolute Threshold The minimum stimulation needed to detect a stimulus half of the time. The absolute threshold for Pretty Little Liars fans is low considering the intensity of their cliffhangers. Subliminal Something below the absolute threshold for conscious awareness. The clues that are in the show are subliminal while being watched, but only make sense when considered with hindsight bias. Weber’s Law The principal that two stimuli must differ by a constant minimum percentage to be able to tell the difference. Apparently the difference between Alison and her twin are too minimal to pass the Liars’ threshold. Sensory Adaptation Diminished sensitivity as a consequence of constant stimulation. After the blow of finding out Toby was A, it really shouldn’t surprise me that Spencer would join the A team as well. Optic Nerve The nerve that carries neural impulses from the eye to the brain. Something Jenna lacks. Sensory Interaction The concept that senses influence each other. While Jenna was blind, her lack of vision altered her taste for food. Selective Attention Focusing attention on one stimulus, such as Spencer ignoring Alex at Homecoming to pay attention to Emily and Toby. Perspectives/Approaches Methods of Research Social Psychology Biological Bases of Behavior Development Learning, Cognition, Language, Intelligence Sensation/Perception Motivation/Emotion States of Consciousness Personality Theories Abnormal Psychology People Foot-In-The-Door Theory The tendency for people who have first agreed to a small request to comply later with a larger request. This would make it easy for the A-Team to attract followers. As soon as they agree to send one taunting text to the Liars as revenge on Alison, the next thing you know they’re running over Hanna with a car. Social Facilitation Improved performance of tasks in the presence of others, often occurs with simple or well-learned tasks, but not with difficult or unmastered ones. When Toby and Spencer ran together, they probably ran faster and longer than if they had been alone.

The Ethical Implications Of Terrorism - 1959 Words

When we approach the people who are terrorists and terrorism, we have to also consider and ask the question â€Å"are their behavior ethical and what the ethical ramifications of their behavior are. First I see terrorism as war and a terrorist in my view is a soldier going to war for certain purpose and reason to destroy. If captured, they should be treated as prisoners of war. Terrorists are engaged in a war like any other: they unite to undertake military action in favor of a specific cause. The fact that they do not represent one individual nation and that they are not at war with a specific list of states does not undermine this: It can be argued that terrorists are not engaged in a war. Their actions are aimed at destruction of civil†¦show more content†¦Terrorists also commit aggression. They have their own armed forces and they too, can deploy armed force in violation of someone else s basic rights. When they do so, they forfeit any right not to suffer the consequen ces of receiving death in response. Terrorists commit aggression when they act, since terrorism is precisely the use of random violence especially as a killing force against civilians, with the intent of spreading fear throughout all population. Thus the immediate federal response to the World Trade Center attack by some terrorist group was the passage of the Patriot Act which included the following elements with some to strengthen domestic security and some with ethical issues. The first section pertains to the country’s protection of civil liberties, authorizes federal money to accomplish much of the act s provisions, allows the Secret Service to create a nationwide electronic crime task force. The president can confiscate the property of any foreign person who is believed to have aided in a war or attack on the United States. The act gives the ability to law-enforcement agencies to conduct surveillance on agents of foreign powers. intercept communications related to terrorist activities, allows law-enforcement agencies to share information in terrorist activities with federal authorities, authorizes roving surveillance by
