Health Anxiety (Hypochondriasis): an Emotional Disorder in An Alternative Taxonomy

The DSM-5 revision of the health anxiety classification (i.e., hypochondriasis) highlights deficiencies in the present DSM taxonomy and the need to consider an alternative. Health anxiety is a clinical syndrome that has been and remains difficult to classify in the DSM system. We argue that the current DSM-5 proposal that splits this syndrome between two diagnoses, somatic symptom disorder (SSD) and illness anxiety disorder (IAD), has significant limitations. We anticipate that SSD will problematically increase comorbidity because criteria for this syndrome feature nonspecific symptoms that overlap with depressive and anxiety disorders. Further, the proposed IAD criteria are overly restrictive and not likely to capture the heterogeneous presentation of individuals with anxiety about their health. We propose an alternative organization that will increase the clinical utility and construct validity of many DSM-IV-TR, Axis I disorders, including health anxiety. This taxonomy, proposed by Goldberg, Krueger, Andrews and Hobbs, is based on the shared etiology of syndromes called emotional disorders. The emotional disorders include health anxiety, other somatoform, unipolar depressive, and anxiety disorders, all of which share the risk factor of negative emotionality/neuroticism (NE/N). We propose a research agenda to support this alternative taxonomy.
First-year law students’ construction of professional identity through writing

While there is a considerable body of research on law student identity construction based on interviews and transcripts of classroom talk, there is very little work based on student written texts. In this article two letters of advice written by beginning law students are analysed, using Ivanic and Camps’s (2001) framework, as an example of identity formation. Legal identity is argued to be formed by students’ attempts to accommodate a dynamic, partial, practitioner role of provider of advice to the traditional analytic focus of the law student. The process of accommodation is evident in the language of the letters, which show disfluencies resulting from attempts to combine different roles into a coherent legal identity. Comparison with a professionally written letter suggests that, rather than seeking to shape a coherent position, lawyers are able simultaneously to hold incompatible perspectives, concealing the tensions by foregrounding some perspectives and backgrounding others.
A model to study the effect of selective anodic oxidation on ultrathin gate oxides

We have studied the effect of selective anodic oxidation on ultrathin (22-31 /spl Aring/) silicon dioxide grown at different temperatures ranging from 600/spl deg/C to 875/spl deg/C, on both p- and n-type substrates. A model based on the concept of filling of pinholes by selective anodic oxidation is presented to quantitatively explain the reduction in the gate leakage current of the MOS capacitors after selective anodic oxidation.
Finding Top-k Preferable Products

The importance of dominance and skyline analysis has been well recognized in multicriteria decision-making applications. Most previous studies focus on how to help customers find a set of &#x201C;best&#x201D; possible products from a pool of given products. In this paper, we identify an interesting problem, finding top-k preferable products, which has not been studied before. Given a set of products in the existing market, we want to find a set of k &#x201C;best&#x201D; possible products such that these new products are not dominated by the products in the existing market. We study two problem instances of finding top-k preferable products. In the first problem instance, we need to set the prices of these products such that the total profit is maximized. We refer such products as top-k profitable products. In the second problem instance, we want to find k products such that these k products can attract the greatest number of customers. We refer these products as top-k products. In both problem instances, a straightforward solution is to enumerate all possible subsets of size k and find the subset which gives the greatest profit (for the first problem instance) or attracts the greatest number of customers (for the second problem instance). However, there are an exponential number of possible subsets. In this paper, we propose solutions to find the top-k profitable products and the top-k popular products efficiently. An extensive performance study using both synthetic and real data sets is reported to verify the effectiveness and efficiency of proposed algorithms.
WicLoc: An indoor localization system based on WiFi fingerprints and crowdsourcing

WiFi fingerprint-based indoor localization techniques have been proposed and widely used in recent years. Most solutions need a site survey to collect fingerprints from interested locations to construct the fingerprint database. However, the site survey is labor-intensive and time-consuming. To overcome this shortcoming, we record user motions as well as WiFi signals without the active participation of the users to construct the fingerprint database, in place of the previous site survey. In this paper, we develop an indoor localization system called WicLoc, which is based on WiFi fingerprinting and crowdsourcing. We design a fingerprint model to form fingerprints of each location of interest after fingerprint collection. We propose a weighted KNN (K-Nearest Neighbor) algorithm to assign different weights to APs and achieve room-level localization. To obtain the absolute coordinate of users, we design a novel MDS (Multi-Dimensional Scaling) algorithm called MDS-C (Multi-Dimensional Scaling with Calibrations) to calculate coordinates of interested locations in the corridor and rooms, where anchor points are used to calibrate absolute coordinates of users. Experimental results show that our system can achieve a competitive localization accuracy compared with state-of-the-art WiFi fingerprint-based methods while avoiding the labor-intensive site survey.
Genetic Variation of the Bloom-Forming Cyanobacterium Microcystis aeruginosa within and among Lakes: Implications for Harmful Algal Blooms

ABSTRACT To measure genetic variation within and among populations of the bloom-forming cyanobacterium Microcystis aeruginosa, we surveyed a suite of lakes in the southern peninsula of Michigan that vary in productivity (total phosphorus concentrations of ∼10 to 100 μg liter−1). Survival of M. aeruginosa isolates from lakes was relatively low (i.e., mean of 7% and maximum of 30%) and positively related to lake total phosphorus concentration (P = 0.014, r2 = 0.407, n = 14). In another study (D. F. Raikow, O. Sarnelle, A. E. Wilson, and S. K. Hamilton, Limnol. Oceanogr. 49:482-487, 2004), survival rates of M. aeruginosa isolates collected from an oligotrophic lake (total phosphorus of ∼10 μg liter−1 and dissolved inorganic nitrogen:total phosphorus ratio of 12.75) differed among five different medium types (G test, P of <0.001), with higher survival (P = 0.003) in low-nutrient media (28 to 37% survival) than in high-nutrient media. Even with the relatively low isolate survivorship that could select against detecting the full range of genetic variation, populations of M. aeruginosa were genetically diverse within and among lakes (by analysis of molecular variance, Φsc = 0.412 [Φsc is an F-statistic derivative which evaluates the correlation of haplotypic diversity within populations relative to the haplotypic diversity among all sampled populations], P = 0.001), with most clones being distantly related to clones collected from lakes directly attached to Lake Michigan (a Laurentian Great Lake) and culture collection strains collected from Canada, Scotland, and South Africa. Ninety-one percent of the 53 genetically unique M. aeruginosa clones contained the microcystin toxin gene (mcyA). Genotypes with the toxin gene were found in all lakes, while four lakes harbored both genotypes possessing and genotypes lacking the toxin gene.
How Family Caregivers of Persons with Alzheimer Disease Achieve Mental Breaks: Preliminary Analysis from a Qualitative Study

There has been growing awareness that respite for family caregivers of persons with Alzheimer Disease can be conceptualized as a positive inner psychological experience as well as a service to provide a physical break. Little is known, however, about the specific activities and strategies caregivers use to achieve therapeutic mental breaks from caregiving concerns. This study examined the strategies and circumstances identified by 15 adult primary caregivers as providing mental breaks. Caregivers participated in two qualitative interview sessions and follow up member checks. Case-by-case and cross-case analyses, and structural synthesis were conducted to develop a working model describing mental breaks. This paper overviews the model, presents two cases illustrating model components, and provides preliminary implications for practice to stimulate therapists' thinking about applications for helping caregivers achieve mental breaks.

Hindu Traditions and Nature: Survey Article

The scholarly investigation of the convergences between Hindu traditions and the natural world is a relatively recent endeavor, having arisen in the wake of similar projects seeking to identify the intersections between religion, culture, and nature. Partly a response to present and looming environmental threats, this effort has resulted in a wide range of material, from a more general "environmental assessment" of the tradition(s) in question to specific inquiries about the social, economic, and demographic factors that impinge upon contemporary Indians' understandings of nature. This literature review provides an overview of these materials and should offer readers a sense of the topics that have received the most attention from scholars to date.
Cellular Repressor of E1A-Stimulated Genes Is a Critical Determinant of Vascular Remodeling in Response to Angiotensin II

Objective— Cellular repressor of E1A-stimulated genes (CREG) is a lysosomal glycoprotein implicated in maintaining vascular homeostasis. Here, we have hypothesized that CREG is a critical target of intervention for the prevention of hypertensive vascular remodeling. Approach and Results— CREG gene expression was significantly decreased accompanied by an upregulated expression of angiotensin II (Ang II) in remodeled vascular tissues of high salt–induced Dahl salt-sensitive rats and Ang II–induced mice. In particular, the downregulation of CREG gene was Ang II specific and independent from blood pressure. Prominent medial hypertrophy and vascular fibrosis in both thoracic aortas and mesenteric arteries were observed in CREG+/− mice infused with Ang II than in CREG+/+ mice, but blunted response in CREG+/+ mice received recombinant human CREG protein, suggesting that changes in CREG expression account for the different phenotype between genotypes. Within a tiled promoter array, E26 transformation-specific-1 binds to CREG promoter at high stringency with the stimulation of Ang II. Moreover, the Ang II–induced E26 transformation-specific-1 directly interacted with the CREG promoter (-1179 and -271 bp) and inhibited its transcription in vascular smooth muscle cells. Selective, pharmacological inhibition of E26 transformation-specific-1 led to restoration of CREG expression in aortas and rescue of experimental vascular remodeling by systemic administration of dominant negative E26 transformation-specific-1 membrane-permeable peptides. Conclusions— CREG is a novel mediator of vascular remodeling in response to Ang II and may be an attractive therapeutic target for prevention of vascular diseases.
Mephedrone use and associated adverse effects in school and college/university students before the UK legislation change.

BACKGROUND Mephedrone is a synthetic cathinone that is commonly used as a recreational drug among those who attend nightclubs. There have been increasing reports of toxicity associated with its use and it was controlled as a Class B drug under the Misuse of Drugs Act (1971) in the UK on 16 April 2010. There has been a suggestion from media reports that mephedrone use is common in children/students but there is no data on the prevalence of its use among the general population. The aim of this study was to determine the prevalence and frequency of use of mephedrone among school and college/university aged individuals and to collect data on the sources of mephedrone and acute harm related to its use. METHODS Data was collected using a questionnaire survey in schools, colleges and universities in the Tayside area of Scotland, UK in February 2010. RESULTS A total of 1006 individuals completed the survey [501 (49.8%) males and 505 (50.2%) females], of whom 349 classified their educational institute as a school and 657 as a college/university. Among them 205 (20.3%) reported previous use of mephedrone; 23.4% reported using only using mephedrone on one occasion previously, although 4.4% reported daily use. A total of 56% of those who had used mephedrone, reported at least one unwanted effect associated with its use. A total of 17.6% of users reported 'addiction or dependence' symptoms associated with their mephedrone use. A total of 48.8% of users sourced mephedrone from street level dealers, 10.7% from the Internet. CONCLUSION We have shown in this study that the use of mephedrone among school and college/university students is common and that users found it easy to obtain. There was a high prevalence of unwanted effects associated with its use. Further work is needed to determine the impact of the recent changes in the UK legislation relating to mephedrone and other related cathinones and whether this has been effective in reducing the prevalence of mephedrone use.
The Importance of Place for International Students’ Choice of University

The scholarly bias toward Western and English-speaking settings in the study of international education overlooks the experiences of international students in emerging education hubs in Asia. To redress this imbalance, this article offers insights into the crucial role of place in the study destination choices of a group of international postgraduate students currently enrolled at a Malaysian university. Findings from semi-structured qualitative interviews conducted with 33 students indicated that place—and specifically the pull factors of the country of Malaysia—had a primary role in their choice of overseas university. More significant than the individual attributes of any one higher education institution, key social and cultural pull factors included the sense of Malaysia as a safe environment, shared cultural values with the students’ own background, the financial benefits derived from low tuition fees and low cost of living, proximity to the students’ home country as well as access to culturally important items such as halal and other dietary requirements. Understanding the significance of such national-level pull factors in study destination choice has important implications for the Malaysian government’s strategy of competing in the global market for international students.
Insomnia Associated with Depressive Disorder: Primary, Secondary, or Mixed?

Background: Insomnia is a common problem that is known to occur during depression. However, literature still debates whether insomnia is part of depression or a separate entity. Materials and Methods: Subjects presenting with depressive disorder according to DSM-IV-Text Revision criteria were recruited after seeking informed consent. Clinical interview was performed with the help of Mini International Neuropsychiatric Interview Plus. Their demographic data and depression related history were recorded. Depression severity was assessed by using Hamilton Rating Scale for Depression. Diagnosis of insomnia was made with the help of International Classification of Sleep Disorders-2 criteria. Type of insomnia, its duration, and its relationship with depressive illness were specifically asked. If any subject fulfilled criteria for more than one type of insomnia, both were recorded. Statistical analysis was done with the help of statistical package for social sciences (SPSS) version 17.0. χ2 test, independent sample t test, and Pearson's correlation were performed. Results: A total of 54 subjects were enrolled in this study. Primary insomnia was seen in 40.7% cases and secondary insomnia in 58.8% cases; 27.3% subjects did not experience insomnia along with depressive disorder. In the primary insomnia category, adjustment insomnia was most prevalent (63.6%), and in secondary insomnia group, insomnia due to depressive disorder was most frequent (59.3%). Interestingly, primary insomnia often followed an onset of depressive illness (P=0.04), while secondary insomnia preceded it (c2 =11.1; P=0.004). The presence of either type of insomnias was not influenced by duration of depressive illness, number of depressive episodes, and duration of current depressive episode. On the other hand, duration of insomnia was positively correlated with total duration of depressive illness (P=0.003), number of episodes (P=0.04), and duration of current depressive episode (P<0.001). Conclusion: Primary insomnia is common in subjects with depression, and it usually follows depressive illness. On the other hand, secondary insomnia often precedes the onset of depressive illness. Duration of insomnia positively correlates with duration and frequency of depressive episodes.
Field Measurements of Induced and Remanent Moments of Unexploded Ordnance and Shrapnel

Magnetometry is a widely used technique for clearance of areas contaminated with unexploded ordnance. The discrimination of hazardous ordnance from nonhazardous items is possible using apparent remanence if ordnance is shock demagnetized on impact with the ground. We developed a mobile device, the Magnetic Remanence Interrogation Platform (MRIP), for measuring the induced and remanent moments of steel samples. The MRIP comprises six three-component fluxgate magnetometers symmetrically distributed around a rotating sample holder. Samples are placed on the holder and are slowly spun through two complete rotations. The measurement is repeated after the sample is physically rotated by 90deg so that the previous up direction points east. The MRIP platform was deployed to two field sites. At the first site, 76- and 90-mm projectiles were measured. Most had relatively low remanent magnetization relative to the induced, suggesting that shock demagnetization occurs. Variations in the remanent moments of different specimens of 90-mm projectiles were attributed to variations in the type of steel used. There was a strong correlation of the direction of remanent and inducing field during burial, indicating evidence of shock magnetization and/or magnetic viscosity. At the second site, intact and partial 4.2-in mortars as well as shrapnel, base plates, and cultural debris were measured. Most of the base plates and intact mortars had low remanent magnetization, whereas the shrapnel and partial mortars tended to have higher remanent magnetization. The results indicate that there is an inherent risk in using apparent remanence for discrimination as not all ordnance is demagnetized on impact.
An Investigation of the Question-Types Teachers Use to Elicit Information From Children

Background: Teachers are required to report suspected child abuse in many parts of the world, but there is a paucity of research characterising how they question children about wrongdoing. Aims: Because children often speak to multiple people before arriving at a forensic interview it is critical to understand how untrained teachers question children. Sample and Methods: Teachers (n = 47) completed a mock interview, written quiz, and rated their expected performance. Results: In both the interview and quiz, teachers asked few open and many leading questions. Yet, they asked proportionally more open and fewer leading questions on the quiz than during the interview, demonstrating an implicit awareness of good questioning. Holding a higher education level degree was associated with asking fewer questions overall, and fewer leading questions, during the mock interview. Higher perceptions of performance after the mock interview were associated with having asked more open and more specific questions. Conclusions: Overall, teachers asked fewer open questions than desired but also demonstrated some awareness of good interviewing skill. We review the teachers’ performance by highlighting the positive aspects of their interviewing skills, identifying areas for improvement, and making suggestions for enhancing teachers’ abilities to question children about wrongdoing.
Tetrahymena POT1a Regulates Telomere Length and Prevents Activation of a Cell CycleCheckpoint

ABSTRACT The POT1/TEBP telomere proteins are a group of single-stranded DNA (ssDNA)-binding proteins that have long been assumed to protect the G overhang on the telomeric 3′ strand. We have found that the Tetrahymena thermophila genome contains two POT1 gene homologs, POT1a and POT1b. The POT1a gene is essential, but POT1b is not. We have generated a conditional POT1a cell line and shown that POT1a depletion results in a monster cell phenotype and growth arrest. However, G-overhang structure is essentially unchanged, indicating that POT1a is not required for overhang protection. In contrast, POT1a is required for telomere length regulation. After POT1a depletion, most telomeres elongate by 400 to 500 bp, but some increase by up to 10 kb. This elongation occurs in the absence of further cell division. The growth arrest caused by POT1a depletion can be reversed by reexpression of POT1a or addition of caffeine. Thus, POT1a is required to prevent a cell cycle checkpoint that is most likely mediated by ATM or ATR (ATM and ATR are protein kinases of the PI-3 protein kinase-like family). Our findings indicate that the essential function of POT1a is to prevent a catastrophic DNA damage response. This response may be activated when nontelomeric ssDNA-binding proteins bind and protect the G overhang.
