What Causes Epilepsy? :: Biology Essays Research Papers
What Causes Epilepsy? From GABA to Zinc Epilepsy is "a diverse collection of disorders" (1). In the United States, there are close to one million people with epilepsy-- about 1 in 200 people around the world have epilepsy(3). This is a review of the emerging insights into the mechanisms underlying the most common form of epilepsy, complex partial epilepsy(1). Terminology and Classification of Epileptic Seizures The term seizure refers to a transient alteration of behavior due to abnormal synchronized and repetitive bursts of firing of neurons in the central nervous system. Epilepsy is syndrome of episodic brain dysfunction characterized by recurrent unpredictable spontaneous seizures. Partial seizures begin in a localized brain region, whereas generalized seizures show widespread involvement of both hemispheres. Examples of generalized seizures are absences (petit mal), myoclonic, or tonic-clonic (grand mal) seizures. A complex partial seizure is associated with impairment of consciousness while a simple partial seizure is not. Most complex partial seizures originate from the temporal lobe and are also called temporal lobe seizures. Epileptics frequently have more than one type of seizure. When simple partial seizure precedes a complex partial seizure, it is referred to as an aura. More recent classifications of epileptic syndromes incorporate such features as etiology, age of onset, and th e different combinations of seizures that an epileptic has. Other commonly used terms include ictal (of seizure itself) and interictal (between seizures). Convulsion implies ictal behavior with vigorous motor activities. Status epilepticus denotes a very prolonged seizure or series of seizures occurring so frequently that full recovery of brain function does not occur interictally (1). Complex partial seizures constitute a major percentage of epilepsies and as a result of impaired consciousness are rather disabling. They are often medically intractable in that the administration of medication will not control the seizures. Most cases of complex partial epilepsy appear to stem from an abnormality in the temporal lobe, since partial resection of the temporal lobe, including the mesial structures, hippocampus, and amygdala, virtually eliminates seizures in more than 80% of selected patients. Examination of tissues of the surgical specimens and autopsy studies of patients with chronic temporal lobe epilepsy most often reveal sclerosis of the hippocampus, termed Ammons horn sclerosis, which is characterized by a marked loss of the principal neurons of hippocampus (1). Jackson and his Early Theory on Epilepsy and Brain Organization In the 1800s, it was noted by Jackson that epileptic seizures begin in isolated parts of the body such as the thumb and from there spread to neighboring regions perhaps the arm and then to the rest of the body.

Analysis of a Media Sourceââ¬â¢s Coverage on a Research
The Wall Street Journal published an article regarding a recent psychopharmacology study on depression done by Dr. Hunter that investigated whether pre-medication brain activity corresponded with treatment outcome. In addition, the article discusses the interesting results garnered from the placebo group v. medicated group analysis. While the news piece does a fair job in representing the studyââ¬â¢s findings, the author does delve into extrapolations not statistically supported in the actual study. Fifty-one adults who were diagnosed with major depression were used in the study, and this was accurately reported by the news article (Wang, 2006). Hunter et al. investigated whether there were significant differences in ââ¬Å"demographic characteristics, illness history, baseline illness severity, [and] final response[s],â⬠and finding none, pooled the subjects for analysis (2006, p. 1427). This does give the Journal, who must condense the findings for the public, good reason to fail in reporting this. The study is experimental in nature, also using double-blind and randomized assignment to help rid the results of confounding variable input. All of the subjects were given a placebo anti-depressant for a one-week lead-in; after this, half of the individuals were continued on the placebo while the others were given one of two anti-depressants. Electroencephalograph (EEG) readings were taken at the time of enrollment, after the lead-in period, and several times later (over an eight week period). The Wall Street Journal condenses this explanation down, and while the article abandons the jargon of an experimenter, it does give the impression of an experimental method being followed. When the news article explains how the researchers defined their variables they leave out valuable information. The author states that patients with certain brain-patterns ââ¬Å"ended up responding better to antidepressant treatment[s],â⬠but fails to mention how this was evaluated (Wang, 2006, p. 1). A Hamilton depression scale was given to judge improvement, giving reliability to the studyââ¬â¢s findings. However, the news piece does accurately report that EEG was also used, in an attempt to find a decrease in prefrontal lobe activity. This study uses a control group, those maintained on the placebo, and compares their EEGs to those of the medicated group, but the main focus of the research was the search for experimental evidence supporting that the commonly used one-week lead-in can predict treatment outcome via brain imaging. The Wall Street Journal article focuses on only a facet of the study, and one that the researcherââ¬â¢s claim to have nonsignificant support for. Wang states that, ââ¬Å"patients who developed this brain-pattern change ended up responding better â⬠¦ than patients who didnââ¬â¢t,â⬠which is misleading to an audience that has not read the actual research (2006, p. 1). While Hunter et al. do find that their EEG scans were a good indicator of treatment success, they also caution that: Although the placebo and medication group analyses yielded different brain regional predictors of outcomes, because of the absence of statistical group interaction we cannot conclude that changes in â⬠¦ [the differing brain regions] â⬠¦ differentially predicted outcomes (2006, p. 430). The news article wrongly insinuates that the study provided evidence for a brain-pattern that is linked to a good treatment outcome in depression. It is certainly true that this study offered outcomes that encourage research in this direction, and that the author also seems to believe that the EEG-pattern found is ââ¬Å"a good indicatorâ⬠for success, but after reading the actual experiment, Wang seems to have inflated the actual findings. Having critiqued the insinuations of the news piece, the extrapolations made by the author do have some merit. The researchers discovered that both the medicated and the placebo groups had a similar variance ââ¬Å"predicted by the neurophysiological changes occurring during the placebo lead-in phaseâ⬠(Hunter et al. , 2006, p. 1429). They offered some possible causal factors such as ââ¬Å"pharmacotherapeutic alliance and pretreatment expectations,â⬠these results seem to demonstrate a placebo-treatment effect, which offers even more reason to further investigate how a patientââ¬â¢s treatment induction affects his/her progress (Hunter et al. , 2006, p. 1429). Though not mentioned or referenced in the Wall Street Journal item, the ethical issues surrounding this experiment are noted by Hunter et al. Providing individuals suffering from major depression placebos for eight weeks is risky, using a double-blind procedure makes it even more dangerous. While the IRB board of UCLA did require a 15-25 minute counseling session during each patientââ¬â¢s visit, this is a massive step down from the psychopharmacological and psychotherapeutic support offered at the recruitment area (a psychiatric outpatient hospital) (Hunter et al. 2006). Conversely though, this ethical ââ¬Å"patchâ⬠does raise an interesting question for further research, lightly touched on by the studyââ¬â¢s authors; if this psychotherapy (however minute) was responsible for a pre-treatment neurophysiological shift, and the shifts that were indicatory of better treatment outcomes could be identified, research could be done to more effectively meld psychotherapy and medic al psychiatry. It is understandable why media reports often leave out details of a research study, often the conclusions and discussion by the author/s of the study are of more interest to the public. However, when a media piece merely latches onto a nonsignificant observation or a suggestion for future research found in the study, the true findings of the experiment are overshadowed by the speculation of the pieceââ¬â¢s author. When a media source offers information about a study, it is vital to maintain a skeptical and critical mindset towards the findings until they are corroborated by the primary source. It is important to look for information that supports the generalizability of the studyââ¬â¢s findings. In the piece presented above, it is worth noting that the study was done on depressed individuals, other psychopathologies may not have any correlation to the results or conclusions provided. The media also commonly jumps from correlation to causation, whether directly or implicitly. While scientific information is the goal of research, sensitization by the media will usually occur to some degree.

Assessment of the environmental impact of Electric Vehicles Essay
Assessment of the environmental impact of Electric Vehicles - Essay Example Source: Shim et al, 2009, Electric car-Tesla Roadstar Structure and Layout of the two vehicle systems In an electric engine the numbers of components is fewer in number and are simpler in configuration. If one were to trace back the line of components starting from the tyres, the wheel axle connected to the tyres is driven by a motor. Similar to controlling speeds by regulating the quantity of fuel, the accelerator controls the voltage input into the motor which thereby controls the speed of the vehicle. The whole setup is powered by a battery and which can be charged from an external power source by simply plugging on to it. (Markel Tony, 2007) Compared to the IC engine which had power sources taken from the same shaft drive it is essential that power for operating the air conditioner and water pump are taken from individual separate motors. The battery should be connected to the motor using a controller so that large starting torques is avoided. (Electric and Plug-in Hybrid Vehicle s, 2010) This can also bring a certain amount of automation in the working of the motor in regulating speed and bringing forth forward or backward motion. It also protects the motors from being subjected to high loads. A number of batteries are arranged in two slots and must be capable of generating 300V DC. (Basic Electric Car Engine Overview, 1999) The Internal combustion on the other hand has a number of components that are required for its efficient working. A four stroke combustion cycle in an Internal Combustion engine follows the Otto Cycle. (Basic Electric Car Engine Overview, 1999) The combustion and the power thus generated takes place in an enclosed space. This cycle has four strokes which namely are 1. Intake stroke- As the piston contained in the engine begins its downward stroke, the inlet valve opens admitting fresh air that has been mixed with gasoline in a certain ratio, into the system. 2. Compression- The cylinder moves up and compresses the air thereby increasing both its density and temperature. 3. Combustion ââ¬â A spark plug located at the top introduces a spark into this charged mixture. The leads to the downward motion of the piston creating the power stroke. 4. Exhaust- The piston moves back upward thereby expelling the burnt gases outside providing space for fresh intake. Electric vehicles and aerodynamics It is true that the number of components of an electric car is lower than a traditional car and the profile of the electric car can be readily modified to increase its aerodynamic efficiency. However a point of concern is the weight of the batteries that would otherwise increase drag and lower aerodynamic efficiency. By installing an effective nose grille at the front of the car, the air that remains stagnated in the frontal region of the car around the motor and gearbox is rerouted to flow past these areas and thereby reduce drag. The La Chevrolet Malibu has shutters in the lower grille region that are controlled electronicall y and automatically. (Industry, Research and Energy, 2010) As the speed of the vehicle increases the shutters close to allow the air at high speeds to flow past the vehicle. This reduces drag and also gives an impetus to the aerodynamic quality of the vehicle. Fuel efficiency is also increased. (Markel Tony, 2007) In the Honda Civic which has a Hybrid variant has aerodynamic hubcaps that are fixed to the rear end spoilers. This has lead to a reduction of aerodynamic drag from 0.3 to 0.27. The overall effect of

The skills and attributes required to manage a hotel Assignment
The skills and attributes required to manage a hotel - Assignment Example It can be argued that the hospitality industry has transformed itself from a product-focused business to a customer-focused one and from a physical-asset intensive business to an experience-centric one. In order to understand the skills that are required by managers and employees in a hotel to perform better it is important to understand the concept of competencies. Competencies can be described as factors that improve the performance of individuals in jobs. According to the definition provided by Woodruffe (1993), competency provides ââ¬Å"provide the dimension against which people should be assessed for readiness or potential to move into jobs against which they should be appraised and upon which they should be developedâ⬠. Skills has been defined as parameters that helps in achieving environmental goals by maximizing certainty of achievement by minimizing cost and time spent (Wadongo, Kambona and Odhuno, 2011). In the past three decades, large number of researchers has focused on the importance of skills and competencies required to run hotels. Skills and competencies are important for both managers and graduates who chose to enter in the hospitality industry. The ability to take initiative has been identified as one of the biggest skills needed to run hotels on the part of managers. This is because initiative can be identified as a parameter that is able to gain support and motivation from others. Hotels are visited by customers from all over the world and managers needs to guarantee satisfaction for the guests. In order to manage the guests and provide them proper satisfaction managers need to have three major types of skills namely conceptual skills, technical skills and human skills. Requirement of skills are further dependent on the hierarchy of the organization and the type of work of the employees. This implies
