The Racial Landscape of Social Networking Sites: Forging Identity, Community, and Civic Engagement

This study examines how adolescents and emerging adults forge identity, community, and civic engagement in public discussions online. Using forty-eight race-related group sites from Facebook and MySpace, this study outlines the reasons groups formed and the discourse practices in which participants engaged. Thematic analysis revealed that group formation revolved around the expression and exploration of identity, creating racial safe havens, education, advocacy, and general discussions about race and race-related issues. Within a given group site's Brendesha M. Tynes is an assistant professor of educational psychology and African American studies at the University of Illinois at Urbana-Champaign. Her research focuses on the role of the Internet in adolescent and emerging adult development with special attention to online victimization, racial identity, intergroup interaction, psychosocial and educational outcomes, and Internet safety. * Elizabeth L. Garcia is currently a doctoral student in the Child Development Division in the Educational Psychology program at the University of Illinois at Urbana-Champaign. Her research interests include racial and ethnic identity and discourse in media, selfconcept, and peer sexual harassment and bullying. "* Michael T. Giang is currently an assistant professor of psychology at Mount Saint Mary's College in Los Angeles, CA. He received his Ph.D. in psychological studies in education from the University of California and a MA. in general experimental psychology from California State University. His research interests include peer harassment, acculturation, ethnic identity, and the Internet as a context and tool for identity development. **** Nicole E. Coleman is a M.Ed. student in school counseling at Loyola University in Chicago. She is interested in the mental health of underrepresented youth in urban areas. I/S: A JOURNAL OF LAW AND POLICY discussion forum threads, participants' discourse centered on topics such as racial/ethnic pride, heritage, diversity/hybridity, community issues, historical events, and the nature of racism. In addition, participants posting in the discussion forums engaged in racial/ethnic selfcategorization, information sharing, policing media for racist infractions, and political organizing. Findings suggest that social network sites and their affordances provide this generation with a unique opportunity to engage in complex discussions about race with those expressing divergent views, those who are similarly positioned, as well as those that are more advanced and culturally sensitive. Despite the presence of online racial discrimination, groups on social network sites are important tools that empower youth to construct identities that counter dominant discourses about underrepresented groups. They also allow group members to become powerful political forces that collectively can help to reshape aspects of the American racial landscape, as was the case with social media more broadly in the 2oo8 presidential election.
A multicenter, add-on randomized controlled trial of low-dose d-serine for negative and cognitive symptoms of schizophrenia.

BACKGROUND Observations that antagonists of the N-methyl-d-aspartate (NMDA) receptor of glutamatergic neurons can mimic symptoms of schizophrenia have raised the hope that NMDA agonists can improve symptoms. On the basis of encouraging results of trials in which NMDA agonists were added to antipsychotics, we conducted an adequately powered randomized controlled trial adding d-serine, an NMDA modulator, to antipsychotics. METHOD This study was a 195-patient, multicenter, double-blind, randomized, placebo-controlled, 16-week trial of d-serine 2 g/d as an add-on treatment to antipsychotics. Subjects had DSM-IV schizophrenia or schizoaffective disorder and were inpatients or outpatients stabilized on antipsychotics, with persistent negative symptoms. The primary outcome measures were changes in negative symptoms and cognition as measured by the Scale for the Assessment of Negative Symptoms (SANS) and the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) battery, respectively. The study was performed between 2003 and 2007. RESULTS Mean total Positive and Negative Syndrome Scale scores at baseline were 75.5. Subjects receiving d-serine and placebo improved in scores on the SANS and MATRICS, but no significant differences were observed between groups: improvement on SANS was 11.4% for d-serine vs 14.8% for placebo, F1,147=1.18, P=. 32; and improvement on MATRICS was 6.8% for d-serine vs 6.1% for placebo, F1,125=0.96, P=. 39, respectively. d-Serine was well tolerated. DISCUSSION This study did not find a significant difference between drug and placebo. However, the results are limited by a relatively large placebo response and somewhat lower-achieved doses than in prior studies. Future studies will administer higher doses and will attempt to affect the NMDA receptor using other mechanisms, such as agonists of the presynaptic metabotropic glutamate 2/3 receptor or glycine reuptake inhibitors. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT00138775.
Deep Learning for Punctuation Restoration in Medical Reports

In clinical dictation, speakers try to be as concise as possible to save time, often resulting in utterances without explicit punctuation commands. Since the end product of a dictated report, e.g. an out-patient letter, does require correct orthography, including exact punctuation, the latter need to be restored, preferably by automated means. This paper describes a method for punctuation restoration based on a state-of-the-art stack of NLP and machine learning techniques including B-RNNs with an attention mechanism and late fusion, as well as a feature extraction technique tailored to the processing of medical terminology using a novel vocabulary reduction model. To the best of our knowledge, the resulting performance is superior to that reported in prior art on similar tasks.
Hodgkin's disease and pemphigus

The second case of pemphigus associated with Hodgkin's disease is reported. Circulating pemphigus auto‐antibodies were detected in this patient and cell‐mediated (T cell) immunity was markedly depressed. It is postulated that this T‐cell immunodepression predisposed the patient to the development of pemphigus.
Repellent Constituents of Essential Oil from Citrus wilsonii Stem Barks against Tribolium castaneum

The essential oil obtained from Citrus wilsonii Tanaka stem barks with hydrodistillation was investigated by GC-FID and GC-MS. The main components of the essential oil were identified to be nerol acetate (44.5%), nerol (13.6%), citronellyl propionate (13.5%) and α-terpineol (3.6%). Among them, the four active constituents, predicted with a bioactivity-test, were isolated and identified as nerolacetate, nerol, citronellyl propionate and α-terpineol. It was found that the essential oil of C. wilsonii stem barks possessed strong repellency (86% and 92%, respectively, at 78.6 nL/cm2, after 2 and 4 h treatment) against Tribolium castaneum adults. Repellency of the four active compounds was also determined. Nerolacetate, nerol, citronellyl propionate and α-terpineol were strongly repellent (100%, 100%, 90% and 96%, respectively, at 15.7 nL/cm2, after 2h treatment) against T. castaneum. Nerol exhibited the same level of repellency as the positive control, DEET. The results indicate that the essential oil of C. wilsonii stem barks and its active compounds have the potential to be developed as natural repellents for control of T. castaneum.
High-Performance $\hbox{In}_{0.7}\hbox{Ga}_{0.3}\hbox{As}$ -Channel MOSFETs With High-$\kappa$ Gate Dielectrics and $\alpha$-Si Passivation

Long and short buried-channel In0.7Ga0. 3As MOSFETs with and without alpha-Si passivation are demonstrated. Devices with alpha-Si passivation show much higher transconductance and an effective peak mobility of 3810 cm2/ V middots. Short-channel MOSFETs with a gate length of 160 nm display a current of 825 muA/mum at Vg - Vt = 1.6 V and peak transconductance of 715 muS/mum. In addition, the virtual source velocity extracted from the short-channel devices is 1.4-1.7 times higher than that of Si MOSFETs. These results indicate that the high-performance In0.7Ga0. 3 As-channel MOSFETs passivated by an alpha -Si layer are promising candidates for advanced post-Si CMOS applications.
Multiple vulnerabilities and maternal healthcare in Vietnam: findings from the Multiple Indicator Cluster Surveys, 2000, 2006, and 2011

Background Knowledge of the aggregate effects of multiple socioeconomic vulnerabilities is important for shedding light on the determinants of growing health inequalities and inequities in maternal healthcare. Objective This paper describes patterns of inequity in maternal healthcare utilization and analyzes associations between inequity and multiple socioeconomic vulnerabilities among women in Vietnam. Design This is a repeated cross-sectional study using data from the Vietnam Multiple Indicator Cluster Surveys 2000, 2006, and 2011. Two maternal healthcare indicators were selected: (1) skilled antenatal care and (2) skilled delivery care. Four types of socioeconomic vulnerabilities – low education, ethnic minority, poverty, and rural location – were assessed both as separate explanatory variables and as composite indicators (combinations of three and four vulnerabilities). Pairwise comparisons and adjusted odds ratios were used to assess socioeconomic inequities in maternal healthcare. Results In all three surveys, there were increases across the survey years in both the proportions of women who received antenatal care by skilled staff (68.6% in 2000, 90.8% in 2006, and 93.7% in 2011) and the proportions of women who gave birth with assistance from skilled staff (69.9% in 2000, 87.7% in 2006, and 92.9% in 2011). The receipt of antenatal care by skilled staff and birth assistance from skilled health personnel were less common among vulnerable women, especially those with multiple vulnerabilities. Conclusions Even though Vietnam has improved its coverage of maternal healthcare on average, policies should target maternal healthcare utilization among women with multiple socioeconomic vulnerabilities. Both multisectoral social policies and health policies are needed to tackle multiple vulnerabilities more effectively by identifying those who are poor, less educated, live in rural areas, and belong to ethnic minority groups.
Local distribution of the parts of unequal partitions in arithmetic progressions II

In [4], Andras Sarkozy and the authors proved that for almost all unequal partitions of an integer n, the parts are evenly distributed in residue classes modulo d for d = o(n^(1/2)). In this paper, we study very precisely the local distribution in arithmetic progressions of the parts of unequal partitions. We obtain some asymptotic formulae for the number of unequal partitions of n with exactly N r parts congruent to r mod d, 1 6 r 6 d. Our results show that (N 1 ,. . , N d) behaves like a random Gaussian vector. This illustrates the fact that the distribution of the parts of unequal partitions in residue classes is much more uniform that in the case of unrestricted partitions.
Ischemia-modified albumin and NT-prohormone-brain natriuretic peptide in peripheral arterial disease

Abstract Cardiovascular disease is the leading cause of mortality and morbidity in Western countries. Despite its remarkable medical and social consequences, the prevalence of peripheral arterial disease (PAD) is often underestimated among atherosclerotic disorders. So far, little is known about the behavior of traditional and emerging markers of ischemic heart disease that should allow the reliable identification of PAD patients at increased risk of developing myocardial ischemia and heart failure or dysfunction. To investigate this topic, we measured cardiac troponin T (cTnT), ischemia-modified albumin (IMA) and NT-prohormone-brain natriuretic peptide (NT-proBNP)in 35 consecutive patients with clinically ascertained PAD (stage 2–4, according to Lériche-Fontaine) asymptomatic for chest pain and current heart failure, and 20 controls displaying moderate to high cardiovascular risk factors (hypertension, diabetes, hyperlipidemia), but with no clinical evidence of PAD. Although the concentrations of cTnT and IMA were not statistically increased in PAD patients, NT-pro-BNP values were substantially higher in PAD patients than in controls (62.6 vs. 7.4pmol/L, p<0.0001). Thepercentage of subjects displaying values exceeding the specific NT-proBNP diagnostic threshold (>14.8pmol/L) was also significantly different between PAD patients and controls (74% vs. 10%, p<0.001). After excluding PAD patients exceeding the 0.01ng/mL cTnT cutoff value indicative of current ischemic cardiac involvement, the median concentration of NT-proBNP remained statistically increased (28.0 vs. 5.8pmol/L, p<0.0001). Taken together, these results indicate that NT-proBNP, but not IMA, is substantially increased in PAD patients. This finding suggests that such patients, even though asymptomatic, might develop myocardial dysfunction, and thus warrant further investigation.
NATURAL SELECTION OF ALLOZYME POLYMORPHISMS: A MICROSITE TEST REVEALING ECOLOGICAL GENETIC DIFFERENTIATION IN WILD BARLEY

Allozymic variation in proteins encoded by 25 loci was analyzed electrophoretically in 1982 and 1983 in 356 individual plants from a dense population of wild barley, Hordeum spontaneum, the progenitor of cultivated barley. The test involved six microniches organized in a mosaic pattern in the open Tabor oak forest at Neve Ya'ar, Israel. The microniches were i) sun‐soil, ii) sun‐rock, iii) shade‐soil, iv) shade‐rock, and the contact zones: v) soil periphery of the sun‐rock microniche, and vi) soil periphery of the shade‐rock microniche. Discriminant analysis indicated significant multilocus allozymic differentiation between the microniches. Our results suggest that allozyme polymorphisms in wild barley are at least partly adaptive and differentiate predominately by microniche ecological selection, rather than by stochastic processes and/or neutrality of allozymic variants.
Intermittent intramuscular clodronate therapy: a valuable option for older osteoporotic women.

SIR—Bisphosphonates are a heterogeneous group of molecules, stable in biological environments, that resemble pyrophosphates compounds used in technical chemistry for calcium binding. All bisphosphonates have high affinity to bone minerals and inhibit bone resorption by reducing osteoclast number and activity; therefore, they are used in disorders associated with excessive osteoclast-mediated bone resorption [1]. Clodronate, one of the bisphosphonate clinically available, has been proved useful in decreasing bone resorption in Paget’s disease, osteolytic bone metastasis and in patients with malignancy-associated hypercalcaemia [2–6]. Several studies have shown that clodronate decreases the number and rate of vertebral and non-vertebral fractures in patients with breast cancerand myeloma-related osteolysis [6– 9] and relieves metastatic bone pain caused by solid tumours with consequent improvement in quality of life [10, 11]. Clodronate, administered by the oral or parental route, has been used effectively in preventing and treating postmenopausal bone loss [12–18] and recently a 3-year multicentre, double-blind, placebo-controlled trial has demonstrated that oral administration of clodronate (800 mg/day) reduces fracture risk in osteoporotic postmenopausal women and in patients with secondary osteoporosis [18]. The 46% reduction of vertebral fracture incidence reported is comparable to that obtained with other anti-resorptive therapies [19–21] and already evident after 1 year of therapy [22]. No data are available concerning the use of clodronate and its effects on pain in older people with osteoporosis. In Italy, clodronate is available for intramuscular (i.m.) administration, representing a useful alternative for osteoporotic patients who have contraindications or intolerance to bisphosphonate oral preparations, and may be particularly valuable in older patients who already receive several medicaments orally. Therefore, the aim of the present study was to verify the efficacy of an intermittent i.m. administration of clodronate (100 mg every 1 or 2 weeks) on vertebral and femoral bone mineral density (BMD) and on subjective pain in a sample of older postmenopausal women.
The relationship between prospective self-rating of alcohol sensitivity and craving and experimental results from two alcohol challenge studies.

OBJECTIVE Determining whether individuals can provide accurate reports of alcohol sensitivity and craving, outside of a laboratory alcohol challenge, has important research and clinical implications. The primary goals of the present study are (1) to test the relationship between prospective self-ratings of the effects of alcohol and alcohol craving, and experimental results from alcohol challenge studies and (2) to examine potential moderators of that relationship. METHOD Participants were heavy drinkers who completed either an intravenous (n = 49) or an oral administration (n = 135) alcohol challenge. Participants were asked to estimate their craving for alcohol in a drinking situation and their subjective intoxication after consuming three drinks. Subjective intoxication and alcohol craving were then assessed during the laboratory alcohol challenge. RESULTS Estimated subjective intoxication and alcohol craving were significant predictors of subjective intoxication and craving measured under laboratory conditions and accounted for, at most, 16% and 37%, respectively, of the variance in laboratory measures. CONCLUSIONS Taken together, these findings suggest that sensitivity to the effects of alcohol and alcohol craving may be measured outside of the laboratory but that scales that are especially designed for nonlaboratory studies may be required.
Aggregative adherence fimbria I expression in enteroaggregative Escherichia coli requires two unlinked plasmid regions

Adherence to HEp-2 cells by many enteroaggregative Escherichia coli (EAggEC) strains is associated with the expression of flexible, bundle-forming fimbriae 2 to 3 nm in diameter, designated aggregative adherence fimbriae I (AAF/I). We have previously reported the molecular cloning and TnphoA mutagenesis of AAF/I genes from the large plasmid of prototype EAggEC strain 17-2 (J. P. Nataro, Y. Deng, D. R. Maneval, A. L. German, W. C. Martin, and M. M. Levine, Infect. Immun. 60:2297-2304, 1992). Here, we report that further mapping and subcloning of AAF/I regions suggest that expression of the fimbriae requires two separate plasmid regions (designated regions 1 and 2). Approximately 9 kb of DNA unnecessary for fimbrial expression separates the two regions; this intervening segment encodes the EAggEC heat-stable enterotoxin (EAST1). Neither region was capable of conferring aggregative HEp-2 adherence (AA) when cloned individually; when the two regions were cloned as a single fragment or when each was cloned into a different vector and introduced into the same E. coli HB101 cell, AA was restored. AA-positive constructs also expressed human erythrocyte hemagglutination, autoagglutination in broth cultures, and the production of AAF/I as detected by immunogold electron microscopy.
THE ROLE OF QUALITATIVE CHARACTERISTICS OF ACCOUNTING INFORMATION ON THE INVESTMENT EFFICIENCY AT MANUFACTURING COMPANIES IN INDONESIA

This study aims to examine whether the attributes of the quality of accounting information reflect the qualitative characteristics of financial statements and examine the effect of the quality of accounting information on investment efficiency. The attributes of the quality of accounting information are predictability, discretionary revenue, discretionary accruals. Investment efficiency is measured by investment inefficiency as underinvestment and overinvestment. The sample was a manufacturing companies listed on the Indonesia Stock Exchange in 2012 until 2015 as many as 493 observations for examine the attributes of the accounting information quality to form factors that reflect the quality of the financial statements. While the sample of 479 observations used to test the influence of the quality of accounting information against underinvestment. Observation of overinvestment was not analyzed in this study because it has only 14 observations. Data analysis technique used is factor analysis and multiple linear regression. The results showed that the three attributes of the accounting information quality form two factors, the first factor called predictability and the second factor is called discretion. Both of these factors reflect the qualitative characteristics of the accounting information. However, the quality of accounting information measured by these two factors has no significant effect on underinvestment. Likewise, the operating cycle, ROA, and age have no effect on underinvestment. Meanwhile, firm size, tangibility , and dummy loss have a significant effect on underinvestment
Algebres touffues. Application au typage polymorphe des objets enregistrements dans les langages fonctionnels

Le langage ml est un langage fonctionnel type polymorphe avec synthese de types. Nous proposons une solution simple pour etendre ml avec des objets enregistrements avec heritage tout en conservant la synthese des types. Simplicite, car les regles de typage de ml ne sont pas modifiees et l'heritage provient uniquement du polymorphisme des operations sur les objets enregistrements. Les objets enregistrements sont des fonctions partielles de domaines finis d'un ensemble denombrable d'etiquettes vers l'ensemble des valeurs. Nous leur associons des types enregistrements qui sont des fonctions partielles de l'ensemble des etiquettes vers l'ensemble des types, que nous rendons totales en definissant des types par defaut pour les etiquettes absentes. Les types enregistrements sont representables de maniere finie dans une algebre de termes munie d'une famille d'equations de distributivite et de commutativite gauche tres severement controlees par des sortes. Nous montrons que cette theorie equationnelle est syntaxique, et nous en deduisons facilement que l'unification y est decidable et unitaire. Puis nous montrons que l'algebre des types de ml peut etre etendue avec une theorie equationnelle reguliere pour laquelle le probleme d'unification est decidable et unitaire. Le langage obtenu est parametre par le jeu de primitives fournies avec leurs types qui realisent les operations elementaires sur les enregistrements. Cette methode devrait s'etendre a des types recursifs et s'appliquer a d'autres langages que ml, notamment a des langages avec l'inclusion de types
Dynamic programming parsing for context-free grammars in continuous speech recognition

The use of context-free grammars in automatic speech recognition is discussed. A dynamic programming algorithm for recognizing and parsing spoken word strings of a context-free grammar is presented. The time alignment is incorporated in to the parsing algorithm. The algorithm performs all functions simultaneously, namely, time alignment, work boundary detection, recognition, and parsing. As a result, no postprocessing is required. From the probabilistic point of view, the algorithm finds the most likely explanation or derivation for the observed input string, which amounts to Viterbi scoring rather than Baum-Welch scoring in the case of regular or finite-state languages. The algorithm provides a closed-form solution. The computational complexity of the algorithm is studied. Details of the implementation and experimental tests are described. >
Pyrrole alkaloids from Bolbostemma Paniculatum

Three pyrrole alkaloids were isolated from Bolbostemma paniculatum. Their structures were elucidated as 4-(2-formyl-5-methoxymethylpyrrol-1-yl)butyric acid methyl ester (1), 2-(2-formyl-5-methoxymethylpyrrol-1-yl)-3-phenylpropionic acid methyl ester (2) and α-methyl pyrrole ketone (3) by spectroscopic techniques. Among them, 1 and 2 are new compounds.
