Self and Collective: Cognition and Social Context

The relationship between the self and the collective is discussed from the perspective of self-categorization theory. Self-categorization theory makes a basic distinction between personal and social identity as different levels of self-categorization. It shows how the emergent properties of group processes can be explained in terms of a shift in self perception from personal to social identity. It also elucidates how self-categorization varies with the social context. It argues that self-categorizing is inherently variable, fluid, and context dependent, as sedf-categories are social comparative and are always relative to a frame of reference. This notion has major implications for accepted ways of thinking about the self: The variability of self-categorizing provides the perceiver with behavioral and cognitive flexibility and ensures that cognition is always shaped by the social context in which it takes place.
Timing of breast cancer surgery during the luteal menstrual phase may improve prognosis.

A meta-analysis has been performed of available retrospective reports concerning the 5-15 year disease-free survival of 5,353 premenopausal breast cancer patients operated on either during the follicular or luteal phases of the menstrual cycle. Patients with surgery performed during the luteal phase (d14-23+) had an overall mean 5% benefit compared to those operated on the follicular phase determined by date of onset of their last menstrual period p=0.02 by Wilcoxon 2-tailed test. When nodal invasion was reported, node-negative patients had a 5 + 2% SEM benefit. Patients with positive nodes had a 34 + 3% SEM increase in survival (p = .05), including both estrogen and progesterone-receptor negative as well as positive neoplasms. In 3 of 4 reports from major cancer treatment centers, each containing 249-1175 cases, risk of recurrent cancer and/or death increased 5 to 6-fold after 10 years for women receiving surgery during d7-14 of their cycle, compared to those resected during d21-36. Improvement in prognosis was greatest for patients with the highest risk of recurrence due to node-invasive disease and receptor dysfunction. Several cell-mediated immunologic factors inimical to metastasis are maximal in the luteal phase of the menstrual cycle, including natural killer cell activity. A new drug which augments natural killer cell activity may extend any beneficial survival results to post-menopausal breast cancer patients in the future. We conclude that accurate menstrual histories should be included in the medical record from now on for all premenopausal women receiving any surgical procedure upon the breast, preferably using an objective method of determining the date of last ovulation. Prospective randomized clinical trials are necessary to determine the full extent of survival benefits of late luteal surgical timing.
The response of the ampullae of Lorenzini of elasmobranchs to electrical stimulation.

1. The ampullae of Lorenzini are sensitive to weak tactile stimulation applied to the ends of their jelly-filled tubes. 2. Either an increase or a decrease in their resting discharge frequency may be caused, each with an opposite after-effect. 3. ‘Adaptation’ is total, being three-quarters completed in 3-8 sec. This ‘adaptation’ probably includes accommodative changes of the tissues. 4. The function of the ampullae is discussed, but no definite conclusion can yet be reached.
Effectiveness of the training material in drug-dose calculation skills.

AIM The aim of study was to evaluate the effectiveness of the training material based on low-level environmental fidelity simulation in drug-dose calculation skills in senior nursing students. METHODS A quasi-experimental design with one group. The sample included senior nursing students attending a nursing school in Turkey in the period December 2012-January 2013. Eighty-two senior nursing students were included in the sample. Data were obtained using a data collection form which was developed by the researchers. A paired-sample t-test was used to compare the pretest and post-test scores. RESULTS The difference between the mean pretest score and the mean post-test score was statistically significant (P < 0.05). CONCLUSION This study revealed that the training material based on low-level environmental fidelity simulation positively impacted accurate drug-dose calculation skills in senior nursing students.
Oligomerization of KCC2 Correlates with Development of Inhibitory Neurotransmission

The neuron-specific K+–Cl− cotransporter KCC2 extrudes Cl− and renders GABA and glycine action hyperpolarizing. Thus, it plays a pivotal role in neuronal inhibition. Development-dependent KCC2 activation is regulated at the transcriptional level and by unknown posttranslational mechanisms. Here, we analyzed KCC2 activation at the protein level in the developing rat lateral superior olive (LSO), a prominent auditory brainstem structure. Electrophysiology demonstrated ineffective KCC2-mediated Cl− extrusion in LSO neurons at postnatal day 3 (P3). Immunohistochemical analyses by confocal and electron microscopy revealed KCC2 signals at the plasma membrane in the somata and dendrites of both immature and mature neurons. Biochemical analysis demonstrated mature glycosylation pattern of KCC2 at both stages. Immunoblot analysis of the immature brainstem demonstrated mainly monomeric KCC2. In contrast, three KCC2 oligomers with molecular masses of ∼270, ∼400, and ∼500 kDa were identified in the mature brainstem. These oligomers were sensitive to sulfhydryl-reducing agents and resistant to SDS, contrary to the situation seen in the related Na+–(K+)–Cl− cotransporter. In HEK-293 cells, coexpressed hemagglutinin-tagged KCC2 assembled with histidine-tagged KCC2, demonstrating formation of homomers. Based on these findings, we conclude that the oligomers represent KCC2 dimers, trimers, and tetramers. Finally, immunoblot analysis identified a development-dependent increase in the oligomer/monomer ratio from embryonic day 18 to P30 throughout the brain that correlates with KCC2 activation. Together, our data indicate that the developmental shift from depolarization to hyperpolarization can be determined by both increased gene expression and KCC2 oligomerization.
Ancient schwannoma of the parapharynx causing dysphagia: a rare entity

A schwannoma is a benign, encapsulated tumour that is derived from neural sheath (Schwann) cells. Approximately 25–40% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck; oropharyngeal occurrence is extremely rare. Among the various histological types of schwannomas reported to date, the ancient (degenerative) variant is the most rare. To our knowledge, this is the first report of an ancient schwannoma in the parapharynx with an extensive oropharyngeal component causing dysphagia. Dysphagia was the prominent symptom because of the location and volume of the lesion. The tumour was excised via a transcervical approach.
Do Reverse-Worded Items Confound Measures in Cross-Cultural Consumer Research? The Case of the Material Values Scale

Most measures of consumer behavior have been developed and employed in the United States. Thus, relatively little is known about the cross-cultural applicability of these measures. Using Richins and Dawson's (1992) Material Values Scale (MVS) as an exemplar, this article focuses on the problems researchers are likely to encounter when employing domestic mixed-worded scales (i.e., scales that contain both positive- and reverse-worded items) in cross-cultural applications. Through an initial study among over 800 adults from the United States, Singapore, Thailand, Japan, and Korea, we show that the cross-cultural measurement equivalence and construct validity of the MVS is challenged by its mixed-worded Likert format. Through a second study among approximately 400 Americans and East Asians, we find that other mixed-worded scales produce similar problems and that the cross-cultural applicability of such scales may be enhanced by replacing items posed as statements with items framed as questions.

The Social Determinants of Health in Association with Women’s Health Status of Reproductive Age: A Population-Based Study

Abstract Background Prioritizing women’s health helps achievement of the 4th and 5th goals of Millennium Development Program. This study aimed to investigate association between social determinants of health and women’s health of reproductive age. Methods This population-based cross-sectional study, using multi-stage sampling procedure was conducted on 770, 15 to 49-year-old women residing in any one of the 22 municipality zones across Tehran, Iran. Eligible women were interviewed at home with SF-36 (Short Form Health Survey) and socio-demographic questionnaires. Social determinants of health contains; ethnicity, education, job, income, and crowding index. Data were analyzed by ANOVA and Multiple Linear Regression using SPSS-16. The threshold of P.V was considered 0.05. Results Overall, 770 women with mean age 33.9±9.3 years were interviewed. Majority of them were married (72.27%), housewives (62.2%), of Persian ethnicity (64.3%), and educated to high school level (43.8%). Age with dimensions of health except role emotional, mental health, and social functioning had significant association with B from -0.65 to -0.16. educational level with dimensions of health except role emotional andsocial functioning had significant association with B from 3.61 to 6.43 (P<0.05). Income with dimensions of health except role physical had significant association with B from -9.97 to -4.42. Conclusion Reflection of unfavorable economic conditions and low education level on negative women’ health experiences are alarming. Interaction between social determinants of health and health status must be considered in policymaking, and there is a need for policies that would enhance health of women in the low education and income brackets.
A GeneTrek analysis of the maize genome

Analysis of the sequences of 74 randomly selected BACs demonstrated that the maize nuclear genome contains ≈37,000 candidate genes with homologues in other plant species. An additional ≈5,500 predicted genes are severely truncated and probably pseudogenes. The distribution of genes is uneven, with ≈30% of BACs containing no genes. BAC gene density varies from 0 to 7.9 per 100 kb, whereas most gene islands contain only one gene. The average number of genes per gene island is 1.7. Only 72% of these genes show collinearity with the rice genome. Particular LTR retrotransposon families (e.g., Gyma) are enriched on gene-free BACs, most of which do not come from pericentromeres or other large heterochromatic regions. Gene-containing BACs are relatively enriched in different families of LTR retrotransposons (e.g., Ji). Two major bursts of LTR retrotransposon activity in the last 2 million years are responsible for the large size of the maize genome, but only the more recent of these is well represented in gene-containing BACs, suggesting that LTR retrotransposons are more efficiently removed in these domains. The results demonstrate that sample sequencing and careful annotation of a few randomly selected BACs can provide a robust description of a complex plant genome.
Starch Characteristics Linked to Gluten-Free Products

The increasing prevalence of coeliac disease (CD) and gluten-related disorders has led to increasing consumer demand for gluten-free products with quality characteristics similar to wheat bread. The replacement of gluten in cereal-based products remains a challenge for scientists, due to its unique role in network formation, which entraps air bubbles. When gluten is removed from a flour, starch is the main component left. Starch is used as gelling, thickening, adhesion, moisture-retention, stabilizing, film forming, texturizing and anti-staling ingredient. The extent of these properties varies depending on the starch source. The starches can additionally be modified increasing or decreasing certain properties of the starch, depending on the application. Starch plays an important role in the formulation of bakery products and has an even more important role in gluten-free products. In gluten-free products, starch is incorporated into the food formulation to improve baking characteristics such as the specific volume, colour and crumb structure and texture. This review covers a number of topics relating to starch; including; an overview of common and lesser researched starches; chemical composition; morphology; digestibility; functionality and methods of modification. The emphasis of this review is on starch and its properties with respect to the quality of gluten-free products.
The Practice of Educational Marketing in Schools

Chris James is Professor of Education Management in the University of Glamorgan Business School and Peter Phillips is Headteacher of West Monmouth School, Pontypool, Gwent. In this paper, the first of three in this edition on different aspects of marketing in education, they stress that this is a relatively new area of interest in educational management. As such it is not surprising to find that much of the literature is characterised by ideas developed in non-educational settings. In this paper they use the notion of the 'marketing mix' to examine the practice of marketing in a number of schools within England and Wales. They find little evidence of the development of sophisticated market driven approaches within the schools they studied.
Supervision and Schizophrenia: the professional identity of Ph.D supervisors and the mission of students' professionalisation

Professionalisation, defined as the transmission of competences adapted to the job-market, is one of the new missions of Doctoral Schools in France. Interviews with supervisors reveal a number of ambivalent attitudes towards this new policy. Supervisors do support the rhetoric of professionalisation, but are powerless to push their students towards other careers than the academic one. We interpret this as a challenge to the academic identity through the modification of what a Ph.D is, which, in turn, impacts on the content, output and meaning of supervision. We show that academics do professionalise their students, but only for the profession they know: academia. They only train the students whom they believe they can acknowledge as future peers, and the on-the-job training provided by Ph.D supervisors is implicitly directed towards academia. The absence of an explicit academic professional identity is discussed, as well as the fact that ‘professionalising’ must relate to a specific professional identity. We argue that only ‘specific’ professional identity can be transmitted, leading to questions about the implementation of the related policy.
Theoretical Orientation Change in Students following a Course in History and Systems of Psychology

Although this study was not primarily an evaluation of the course as awhole, the results do confirm the evaluation reported In Cummlng (1977) The course was successful, well-liked and considered effectlve On the specific question asked as to whether the small student groups should be mixed or streamed the general preference was for mixed groups, this preference was shown by students across the ability range There was no slgn that ether good or slow students generally suffer by be~ng forced to work in mixed-ability groups On the other hand, streamed groups also functioned satisfactorily, w~th the possible exception that homogeneous groups of poor students may not funct~on well In summary, mixed groups are preferred, seem to have no clear disadvantages and posslbly at least one advantage by comparison with streamed groups. Mixed groups are therefore to be preferred. An alternative and also entirely reasonable line of argument starts by questlonlng whether students need be assigned to groups at all Assignment was initially adopted to avoid the possibil~ty that tf students were left to form their own groups good students would naturally group together, leaving the poorer students with only each other The present study can be Interpreted as showing that, whatever students' preferences may be, streamed groups are no less effect~ve than m~xed groups and so even if students did sort themselves into somewhat streamed groups no great harm would result. Some worry might remain over the possibility of extreme LO groups, but self-selection of groups-aver, say, the first few weeks of the course--should have the great advantages that personality clashes should be reduced, particular friends would be able to work together and in general students could to some extent match up on work style and other attributes relevant to working in a group. Group effectiveness and harmony should increase and the need to make changes in group membership during the year should be reduced. This interesting possibility is at present being explored and will be the subject of a future report.
Deep subseafloor microbial cells on physiological standby

Microscopic counts of microbial cells in deep sediment cores retrieved by scientific ocean drilling have revealed the largest living ecosystem on earth: the deep biosphere (1, 2). Hidden beneath the seafloor, a large part of all prokaryotic cells on earth persist under conditions so highly energy-limited that it seems to violate the constraints to life. This deep biosphere is the most understudied ecosystem, inhabited by organisms only distantly related to known laboratory strains. It is not even clear whether the cells are alive and metabolically active, or are dormant or perhaps dead. The report by Morono et al. in PNAS (3) attacks this very basic question with new convincing experiments.
Event-Related Activation in the Human Amygdala Associates with Later Memory for Individual Emotional Experience

The role of the amygdala in enhancing declarative memory for emotional experiences has been investigated in a number of animal, patient, and brain imaging studies. Brain imaging studies, in particular, have found a correlation between amygdala activation during encoding and subsequent memory. Because of the design of these studies, it is unknown whether this correlation is based on individual differences between participants or within-subject variations in moment-to-moment amygdala activation related to individual stimuli. In this study, participants saw neutral and negative scenes and indicated how emotionally intense they found each scene. Separate functional magnetic resonance imaging responses in the amygdala for each scene were related to the participants' report of their experience at study and to performance in an unexpected memory test 3 weeks after scanning. The amygdala had the greatest response to scenes rated as most emotionally intense. The degree of activity in the left amygdala during encoding was predictive of subsequent memory only for scenes rated as most emotionally intense. These findings support the view that amygdala activation reflects moment-to-moment subjective emotional experience and that this activation enhances memory in relation to the emotional intensity of an experience.
Experiential and Contextual Factors that Shape Engineering Interest and Educational Decision-Making Processes among Female Students

This qualitative study explores the formation of educational and vocational goals among female first-year engineering students at two community colleges and one four-year institution, as well as contextual influences on this process. Participants’ pathways to college are also explored, as well as their pathways into engineering. The findings suggest a need for expanded access to experiential learning opportunities and ongoing attention to the role of community colleges in engineering education.
Antioxidant defences in the microaerophilic protozoan Trichomonas vaginalis: comparison of metronidazole-resistant and sensitive strains.

The sensitivity of the microaerophilic protozoan Trichomonas vaginalis to oxygen and products of its reduction, and the antioxidant defences employed by this organism, were investigated. Studies revealed that this amitochondrial flagellate is sensitive to oxygen tensions above those experienced in situ in the vagina (i.e. > 60 microM) and that metronidazole-resistant strains (CDC 85 and IR78) were more sensitive to elevated oxygen levels than a metronidazole-sensitive isolate (1910). In the presence of radical scavengers, inactivation of organisms at 60 microM oxygen was significantly lessened. Investigation of the antioxidant enzymes present in this organism revealed that activities of peroxide-reducing enzymes (e.g. catalase and general peroxidase) were not detectable, but that a cyanide-insensitive, azide-sensitive superoxide dismutase was present in cell extracts. Measurement of thiol-cycling enzymes indicated that NADPH could drive the reduction of oxidized glutathione (thiol reductase); however, the corresponding peroxidase activity was not detected. Analysis of thiols in whole cells of T. vaginalis indicated that glutathione was absent, but high levels of other thiols, propanethiol, methanethiol and H2S, were present. No significant differences were detected in thiol levels or antioxidant enzyme activities on comparison of metronidazole-sensitive and resistant strains. These results indicate that the sensitivity of T. vaginalis to oxygen above physiological levels is due to the lack of adequate peroxide-reducing enzymes and radical-scavenging mechanisms.

The significance of human jagged 1 mutations detected in severe cases of extrahepatic biliary atresia

Mutations of human jagged 1 (JAG1) gene are responsible for Alagille Syndrome (AGS), whose 2 main symptoms are intrahepatic bile duct hypoplasia and pulmonary stenosis. We examined the JAG1 mutation in extrahepatic biliary atresia (EHBA), which is similar in phenotype to AGS, although a different pathogenesis is suggested. In 102 cases of EHBA, 9 missense mutations were detected, including 2 intrafamilial expressions in the propositus and an aunt of one family. These mutations were all missense and sporadic except for those of this particular family. The JAG1 gene mutations were generally found in severely ill patients subjected to liver transplantation at less than 5 years of age. None of the 9 cases of EHBA revealed any of the 5 major symptoms of AGS nor any identical pathological findings after 3 years of follow‐up. Our cases were clearly separated from AGS by pathological findings and clinical features, and could be diagnosed as EHBA and not as atypical AGS. The increase of interleukin 8 (IL‐8) production induced by tumor necrosis factor α (TNF‐α) in Huh 7 cells was suppressed by the coexistence of JAG1 protein. We examined the different influences between wild‐type cells and the 3 kinds of mutants detected in EHBA on Huh 7 cells and found that 2 of 3 mutants showed about half of the repressed activity compared with that of wild type. In conclusion, these results suggest that the JAG1 gene abnormality may be an aggravating factor in EHBA.
