Trapped in the Bell Jar: Mental Illness in College Students

This is a magazine article that explores the rising problem of mental health in college students, focusing on Connecticut. It explores the experiences of three college students dealing with depression and bipolar disorder, a family who lost a child to suicide, and the measures taken by colleges in Connecticut to curb the problem.

Adolescent Meaning Making of Past Experience

This study examined the meaning making processes of self-defining memories in adolescents, as well as how they co-construct the narratives of these events with their parents. The sample consisted of 53 students, aged 12-14, who came in for recorded laboratory sessions to discuss self-defining memories with their parents. These sessions were later coded on levels of meaning making and co-construction. These codes were, then, analyzed with the adolescents’ questionnaire scores regarding friendship quality, internalizing, and externalizing behaviors. The data revealed that adolescents and parents were both rated higher for more complex levels of meaning making and that those rated higher for more complex meaning making abilities had better friendship qualities. The implications of these findings were discussed in terms of their importance for parents supporting their children’s emotional expressivity, narrative abilities, and meaning making strategies.

The Hasse-Minkowski Theorem

The Hasse-Minkowski theorem concerns the classification of quadratic forms over global fields (i.e., finite extensions of Q and rational function fields with a finite constant field). Hasse proved the theorem over the rational numbers in his Ph.D. thesis in 1921. He extended the research of his thesis to quadratic forms over all number fields in 1924. Historically, the Hasse-Minkowski theorem was the first notable application of p-adic fields that caught the attention of a wide mathematical audience. The goal of this thesis is to discuss the Hasse-Minkowski theorem over the rational numbers and over the rational function fields with a finite constant field of odd characteristic. Our treatments of quadratic forms and local fields, though, are more general than what is strictly necessary for our proofs of the Hasse-Minkowski theorem over Q and its analogue over rational function fields (of odd characteristic). Our discussion concludes with some applications of the Hasse-Minkowski theorem.

OLDER WOMEN LIVING WITH HIV/AIDS

The purpose of this study is to fill a gap in the literature by investigating how an ignored population of women, women over age 50, copes with HIV/ AIDS. Older women are referred to as "invisible victims" with regard to HIV/AIDS. Previous research on coping with HIV/ AIDS focuses mostly on men. Of the research that does focus on women, older women are often overlooked. Although older women are a minority compared to other HIV-infected populations in the US, they are just as deserving of recognition and care as any other population. Data was collected through open-ended, in-depth interviews with four women individually. Recruitment of the sample is from several health institutions serving HIV/AIDS populations. The major topics discussed in the interviews include: demographics, what it is like to live with HIV or AIDS, and way of coping with HIV/ AIDS, including social support, religion, and health behaviors. The data analysis process is a qualitative one, with exploration of major themes and presentation of rich descriptions to illustrate those themes. Results from the data show that in terms of coping, all four participants found it most difficult to cope with a different aspect of living with HIV. Regardless of this finding, participants still employed similar coping strategies. As hypothesized, social support and religious/ spiritual support are important aspects in coping with HIV for all participants. The use of education as a coping mechanism was not an anticipated result. Yet, education was a constant theme, whether it was educating oneself about the disease to better understand it or educating others as to prevent them from contracting HIV. A variety of different positive coping strategies were employed by the participants in coping with their HIV, including altering negative health habits and staying optimistic. Negative coping strategies were also employed, but these seemed to be discussed less throughout the interviews. Overall, the results of this study demonstrate the resilience of these women in terms of finding ways of living with HIV instead of dying from HIV.

Ionotropic Glutamate Receptors Show Unique Distribution and Localization in the Dorsal Cochlear Nucleus of the Rhesus Monkey

The dorsal cochlear nucleus (DCN) receives auditory information via the auditory nerve coming from the cochlea. It is responsible for much of the integration of auditory information, and it projects this auditory information to higher auditory brain centers for further processing. This study focuses on the DCN of adult Rhesus monkeys to characterize two specific cell types, the fusiform and cartwheel cell, based on morphometric parameters and type of glutamate receptor they express. The fusiform cell is the main projection neuron, while the cartwheel cell is the main inhibitory interneuron. Expression of AMPA glutamate receptor subunits is localized to certain cell types. The activity of the CN depends on the AMPA receptor subunit composition and expression. Immunocytochemistry, using specific antibodies for AMPA glutamate receptor subunits GluR1, GluR2/3 and GluR4, was used in conjunction with morphometry to determine the location, morphological characteristics and expression of AMPA receptor subunits in fusiform and cartwheel cells in the primate DCN. Qualitative as well as quantitative data indicates that there are important morphological differences in cell location and expression of AMPA glutamate receptor subunits between the rodent DCN and that of primates. GluR2/3 is widely expressed in the primate DCN. GluR1 is also widely expressed in the primate DCN. GluR4 is diffusely expressed. Expression of GluR2/3 and GluR4 in the primate is similar to that of the rodent. However, expression of GluR1 is different. GluR1 is only expressed by cartwheel cells in the rodent DCN, but is expressed by a variety of cells, including fusiform cells, in the DCN of the primate.

School Environments and Behaviors of Students on the Autism Spectrum

This study explores the relationship between the different environments within a school and the stereotyped behaviors of students with autism. The study seeks to identify whether the behaviors of these students are similar or different in the different environments, testing the idea of environment as a stimulus for these behaviors. The study is a naturalistic observational study, and a change in prevalence of these stereotyped behaviors during the duration of the study is not a focus of this study.

Street-Ball: The Myth of the Ghetto Basketball Star

In recent decades, countless scholars have examined the developing trend of African American dominance in United States’ professional sports. Many have hypothesized that this over-representation is caused by the presumed reliance on sports as an avenue out of poverty for the African American youths. This trend, it is believed, has a highly detrimental effect the African American community. In actuality, this argument is flawed because it works under the stereotypical assumption that the overwhelming majority of African Americans come from abject poverty. To dispel this fallacy, the author has analyzed the upbringings of each All-National Basketball League First Team player over the past thirty years. The author discovered that while the majority of the players selected were African American, only a small percentage of these athletes were raised in a poverty-stricken environment. Logically, this would not be the case if poor African Americans relied more heavily on sports than middle-class African Americans. This data proves that stereotypes, not empirical evidence, are the substance of nearly every previous study conducted on the topic.

The Acceleration of Stock Options in Anticipation of FAS 123 (R)

The Financial Accounting Standards Board (FASB) mandated the expensing of stock options with FAS 123 (R). As of March 2006, 749 companies had accelerated the vesting of their employee stock options and avoided a reduction in their reported profits that otherwise would have occurred under the new standard. There are many different motives for the acceleration strategy, and the focus of this study is to determine whether shareholders viewed these motives as either positive or negative. A favorable return subsequent to an acceleration announcement would signify that shareholder's viewed management's motives as positive. An unfavorable return subsequent to an acceleration announcement would signify that shareholder's viewed management's motives as negative. The evidence from this study suggests that shareholders reacted favorably, on average, to acceleration announcements. However, these results lack statistical significance and are based on a small sample, thus, they should be interpreted with caution.

France, Italy, and Spain: Culturally Similar Nations, Yet Drastically Different In Their Roles as European Union Nations

Since France, Italy and Spain are neighboring Western European countries, whose languages and cultures have descended from Latin, it is inevitable that these countries share similarities on many levels. France, Italy and Spain share similar lifestyles, religious values and cultural heritages. Throughout history France, Italy and Spain have experienced many of the same historical events because of their geographical proximity. Now that all three countries are members of the European Union they have become further united by occupying a common area without border controls, and sharing a common market, laws, and currency. While France, Italy and Spain share many commonalities, their opinions and relationships within the European Union are diverse. Although each nation struggles to balance its national identity with its European identity and to maintain its sovereignty while at the same time giving some of it up to the EU, each nation has its own ideas about how much its identity should change and how much sovereignty it should give up to the EU government. Each nation also has unique opinions about what it means to part of the European Union and what the requirements for becoming a member nation should be. Each nation has different goals it hopes to accomplish for its own country and for the European Union. The differing ideas amongst France, Italy and Spain are a result of the variance that exists amongst their political and economic relationships and institutions, which have been molded by the historical experiences of each nation. The focus of this paper will be examining why France, Spain and Italy share many cultural similarities, yet differ so greatly in their roles as members of the European Union. After a brief background on the European Union, I will discuss the cultural similarities France, Italy and Spain share. I will then mention several economic and political differences between the three countries and use supporting evidence to explain why and in what context these differences have arisen

The Effects of Physical and Chemical Modulating Agents on the Induction of Vaccine-Induced Immune Responses

After the development of the viral-based prostate cancer vaccine, Ad5-PSA, much research has been orientated to help enhance the induced immune response by combining the vaccine with physical and chemical modulating agents, more specifically the polymers polyethylenimine (PEI), chitosan, and chitosan coated with CD3 complex antibodies; all previously shown to stimulate an immune response as isolated gene carriers. To compare the vaccine-induced immune responses between the naked vaccine and the polymer-vaccine combinations, a mouse model using the ovalbumin- specific Ad-OVA vaccine was tested using intracellular cytokine staining (ICS), tetramer staining, and cytotoxic T-cell lymphocyte assays to measure the activation of CD8+ T-cells, interferon gamma proteins (INFƒ×), and the induced cytotoxicity to ovalbumin. The Ad-OVA vaccine combined with both chitosan and chitosan with CD3 complex antibodies, both natural polymers, were found to induce similar immune responses to the naked vaccine while the vaccine combined with the synthetic polymer, PEI, diminished the immune response.

Scaling the Costs of 404 Testing to Fit the Needs of Small Public Companies

In July of 2002, the Sarbanes-Oxley Act was passed by Congress, including section 404 which requires the auditors to test and opine on the company's internal controls. Since that time there has been much debate about whether the intended benefits of increased investor confidence and financial statement transparency trump the unexpectedly high compliance costs, especially for public companies with market-caps less than $75 million. Before these companies begin complying in the upcoming year, interest groups are calling for the requirements to be 'scaled' to better fit the needs of these companies. While auditors already are expected to scale their audit approach to each individual client, more must be done to significantly decrease the costs in order to reverse the trend of small companies foregoing listing on U.S. capital markets. Increased guidance from the PCAOB, SEC, and other related parties could help the small-cap companies and their auditors be aware of best practices. Also, exempting industries that already follow similar guidelines or are significantly injured by the compliance requirements could help. Lastly, the controversial proposal of rotational audits could be put in place if the affected parties cooperate to remove the undue burden on these small-cap companies. Without some form of significant action, the investors could soon lose the ability to buy small-cap companies in U.S. markets.

Predator-Induced Plasticity in Spotted Salamanders (Ambystoma maculatum)

The ability to respond plastically to the environment has allowed amphibians to evolve adaptive responses to spatial and temporal variation in predation threat. However, animals exposed to predators may also show costs of plasticity or tradeoffs. This study examines predator-induced plasticity in larval development, behavior, and metamorphosis in the spotted salamander, Ambystoma maculatum. Salamanders were raised in two treatments: with predator cues (a fish predator, genus Lepomis, on the other side of a divided tank), or without predator cues. During the larval stage the predator treatment group experienced higher mortality rates than the no-predator treatment group. Behavioral trials revealed that predator treatment animals ate less than those not exposed, and that this feeding response was immediately inducible and had lasting effects. Animals in the predator treatment group had smaller tail areas during the mid-larval period. Feeding and body size effects may have contributed to increased mortality in the predator-treatment animals. The timing of metamorphic onset was not affected by the presence of predators, but predator-treatment salamanders had shorter snout/vent lengths at metamorphosis. The duration of metamorphosis showed a potentially adaptive plastic response to the presence of predator cues: metamorphosis was longest in the no-predator treatment group, reduced in the predator treatment group, and even further reduced for animals exposed to predator cues only during metamorphosis. Overall, we found a mix of potentially adaptive and costly plastic responses in spotted salamanders.

Behavioral Implications of Knockout for the Dyslexia-Risk Gene Dcdc2 in Mice

Several genetic linkage and epidemiological studies have provided strong evidence that DCDC2 is a candidate gene for developmental dyslexia, a disorder that impairs a person’s reading ability despite adequate intelligence, education, and socio-economic status. Studies investigating embryonic intra-ventricular RNA interference (RNAi) of Dcdc2, a rat homolog of the DCDC2 gene in humans, indicate disruptions in neuronal migration in the rat cortex during development. Interestingly, these anatomical anomalies are consistent with post mortem histological analysis of human dyslexic patients. Other rodent models of cortical developmental disruption have shown impairment in rapid auditory processing and learning maze tasks in affected subjects. The current study investigates the rapid auditory processing abilities of mice heterozygous for Dcdc2 (one functioning Dcdc2 allele) and mice with a homozygous knockout of Dcdc2 (no functioning Dcdc2 allele). It is important to note that this genetic model for behavioral assessment is still in the pilot stage. However, preliminary results suggest that mice with a genetic mutation of Dcdc2 have impaired rapid auditory processing, as well as non-spatial maze learning and memory ability, as compared to wildtypes. By genetically knocking out Dcdc2 in mice, behavioral features associated with Dcdc2 can be characterized, along with other neurological abnormalities that may arise due to the loss of the functioning gene.

Psychiatrists' and Psychiatric APRNs' Views of the Adolescent Mental Health Nurse's Role In the Inpatient Setting

Current perceptions about nurses’ roles and responsibilities are examined in this study, specifically relating to adolescent inpatient MHNs. Psychiatrists and psychiatric advanced practice registered nurses (APRNs), who work with MHNs and have also published scholarly psychiatric articles, were contacted to request their participation in an anonymous survey hosted by SurveyMonkey.com. This research was conducted to examine the stereotypes that exist against nurses within the health care profession itself, as compared to the pre-existing stereotypes displayed by the media’s view of nurses. Due to investigator time constraints, only six subjects participated in the study. Analysis of survey responses revealed four overarching themes. First, MHNs are a critical component of the health care team, emerging as rigorous, independent leaders, although still classified as female and sociable. Second, MHNs complete a wide range of daily activities, many of which go unnoticed by observers, often resulting in mixed feelings regarding whether MHNs are given the respect and recognition deserved. Third, MHNs treat each patient as a person with unique thoughts, feelings, and physical make-up. Fourth, MHNs act as a coordinator of care between various health professionals to provide the patient with a holistic approach to healing.

Differentiation of Human Embryonic Stem Cell (hESC) Derived Pyramidal Neurons

The mammalian cerebral neocortex is a complex six-layered structure containing multiple types of neurons. Pyramidal neurons of the neocortex are formed during development in an inside-out manner, by which deep layer (DL) neurons are generated first, and upper layer (UL) neurons are generated last. Neurons within the six-layered neocortex express unique markers for their position, showing whether they are subplate, deep layer, upper layer, or Cajal-Retzius neurons. The sequential generation of cortical layers, which exists in vivo, has been partially recapitulated in vitro by differentiation of mouse embryonic stem cells (Gaspard et al., 2008) and human embryonic stem cells (hESC) (Eiraku et al., 2008). The timeline of generation of cortical neurons from hESC is still not well defined, and could be very important in the future of cell therapy. In this study we will define timeline for UL and DL neurons for our experimental paradigm as well as test the effects of fibroblast growth factors (FGF) 2 and 8 on this neuronal differentiation. Recent papers suggest that FGFs are critical for forebrain patterning (Storm et al., 2003). Neuronal differentiation after treatment with either FGF2 or FGF8 from hESCs will be examined and the proportion of specific neuronal markers will be analyzed using immunocytochemistry. Our results show that the generated pyramidal neurons will express DL and UL laminar markers in vitro as they do in vivo and that the presence of FGF8 in induction media creates a proliferative effect, while FGF2 induces hESC to differentiate at a higher rate.
