Exploratory Factor Analysis of a Relational Aggression Self-report

Relational aggression (RA) represents a distinct form of bullying and refers to behaviors that harm others through damaging their friendships, their inclusion in social groups, and their feelings of acceptance. RA has been recognized as a significant problem, which has psychosocial and academic consequences for perpetrators, victims and bystanders. This study evaluated a self-report inventory that examined RA in 219 females ages 10 through 18 from Central Pennsylvania. Inter-item correlations revealed that none of the scale’s items were highly correlated and therefore repetitive. An Exploratory Factor Analysis (EFA) with an oblique rotation was used to identify the factors within the Girls Relationship Scale. Two factors were revealed with a “lenient” alpha greater than . 70, representing the factors of “Relationships” and “Substance Abuse. ” A Pearson Correlational analysis found a significant negative relationship between the Age and the Substance Abuse factor (Pearson Correlation= -.166, p=.001), indicating the fact that older girls were more likely to endorse the willingness to smoke cigarettes or use drugs or alcohol if meant being accepted by other girls. A significant correlation was also found between the Age and the Total Scale score (Pearson Correlation= .495, p=.001), indicating that older girls were more likely to answer questions in a more self-assured and knowledgeable manner, or in the desired direction. An ANOVA revealed significant differences between the roles involved in relational aggression including the “bully”, “victim”, “bystander” or “other”, and the “Relationships” factor (p=.002) and between the roles and the Total Scale score (p=.001). Post hoc tests to examine the significant differences further could not be Relational Aggression Scale v performed, however, because of missing data caused by subjects not answering every question. Lack of significance was found between places and situations in which girls think that they have more problems with their relationships and their ethnic heritage and the factor and Total scale scores.

IMBIBITION, GERMINATION AND LIPID MOBILIZATION RESPONSE BY SUNFLOWER SUBJECTED TO SALT STRESS

Salinity is one of the most important abiotic stresses in arid and semi-arid regions that substantially reduce the germination, growth and average yield of major crops. The study was mainly aimed to select the most salt tolerant cultivar of sunflower. Therefore, a pot culture experiment was conducted to study the effects of four different salinity levels having electrical conductivity viz., 1.19, 9.54, 16.48 and 22.38 mS/cm on the imbibition (water uptake), germination and lipid mobilization of seedlings of 4 varieties of sunflower (Helianthus annuus L.) i.e., DO-728, DO-730, Hysun-33 and Suncross843. Salinity levels were prepared by dissolving calculated amount of NaCl, Na2SO4, CaCl2 and MgCl2 (4:10:5:1) in half strength Hoagland culture solution. Imbibition was studied using plastic glasses at an interval of 12 and 24 hours. While germination studies were separately carried out in plastic pots and noted after every 12 hours till 20 days. Whereas, lipid contents of the salt stress germinating seeds were determined at three time intervals viz., 48, 96 and 144 hours of germination. Results showed that there was a linear decrease in imbibition, germination and lipid mobilization as the level of salinity progressively intensifies. Maximum significant reduction in imbibition (12.88%), germination (31.03%) and lipid mobilization (38.62%) is recorded in highest dose of applied salts (22.38 mS/cm). Results further exhibited that maximum significant reduction in imbibition (17.95%) and germination (43.05%) is recorded for variety Suncross-843. While minimum for the same attributes is recorded for variety DO-728. Therefore, in term of imbibitions and germination, DO-728 could be ranked as salt tolerant. Similarly maximum reduction (14.85%) in mobilized lipids is noted for DO-728 and minimum (40.89%) for DO-730. Therefore, in term of lipid mobilization, variety DO-730 could be ranked as salt tolerant and DO-728 as salt sensitive. While remaining 2 varieties i.e., Hysun-33 and Suncross-843 is rated as salt intermediate in response, respectively.
Faster and Cheaper: Parallelizing Large-Scale Matrix Factorization on GPUs

Matrix factorization (MF) is used by many popular algorithms such as collaborative filtering. GPU with massive cores and high memory bandwidth sheds light on accelerating MF much further when appropriately exploiting its architectural characteristics. This paper presents cuMF, a CUDA-based matrix factorization library that optimizes alternate least square (ALS) method to solve very large-scale MF. CuMF uses a set of techniques to maximize the performance on single and multiple GPUs. These techniques include smart access of sparse data leveraging GPU memory hierarchy, using data parallelism in conjunction with model parallelism, minimizing the communication overhead among GPUs, and a novel topology-aware parallel reduction scheme. With only a single machine with four Nvidia GPU cards, cuMF can be 6-10 times as fast, and 33-100 times as cost-efficient, compared with the state-of-art distributed CPU solutions. Moreover, cuMF can solve the largest matrix factorization problem ever reported in current literature, with impressively good performance.
Cache-aware load balancing vs. cooperative caching for distributed search engines

In this paper we study the performance of a distributed search engine from a data caching point of view. We compare and combine two different approaches to achieve better hit rates: (a) send the queries to the node which currently has the related data in its local memory (cache-aware load balancing), and (b) send the cached contents to the node where a query is being currently processed (cooperative caching). Furthermore, we study the best scheduling points in the query computation in which they can be reassigned to another node, and how this reassignation should be performed. Our analysis is guided by statistical tools on a real question answering system for several query distributions, which are typically found in query logs.
“You can't kid a kidder”: association between production and detection of deception in an interactive deception task

Both the ability to deceive others, and the ability to detect deception, has long been proposed to confer an evolutionary advantage. Deception detection has been studied extensively, and the finding that typical individuals fare little better than chance in detecting deception is one of the more robust in the behavioral sciences. Surprisingly, little research has examined individual differences in lie production ability. As a consequence, as far as we are aware, no previous study has investigated whether there exists an association between the ability to lie successfully and the ability to detect lies. Furthermore, only a minority of studies have examined deception as it naturally occurs; in a social, interactive setting. The present study, therefore, explored the relationship between these two facets of deceptive behavior by employing a novel competitive interactive deception task (DeceIT). For the first time, signal detection theory (SDT) was used to measure performance in both the detection and production of deception. A significant relationship was found between the deception-related abilities; those who could accurately detect a lie were able to produce statements that others found difficult to classify as deceptive or truthful. Furthermore, neither ability was related to measures of intelligence or emotional ability. We, therefore, suggest the existence of an underlying deception-general ability that varies across individuals.
Mathematics of Human Motion: from Animation towards Simulation (A View form the Outside)

Simulation of human motion is the subject of study in a number of disciplines: Biomechanics, Robotics, Computer Animation, Control Theory, Neurophysiology, Medicine, Ergonomics. Since the author has never visited any of these fields, this review is indeed a passer-by's impression. On the other hand, he happens to be a human (who occasionally is moving) and, as everybody else, rates himself an expert in Applied Common Sense. Thus the author hopes that this view from the {\em outside} will be of some interest not only for the strangers like himself, but for those who are {\em inside} as well. Two flaws of the text that follows are inevitable. First, some essential issues that are too familar to the specialists to discuss them may be missing. Second, the author probably failed to provide the uniform "level-of-detail" for this wide range of topics.
Low grade marginal zone B cell lymphoma of the breast associated with localised amyloidosis and corpora amylacea in a woman with long standing primary Sjögren’s syndrome

Primary low grade marginal zone B cell lymphoma (MZL) of the breast and localised mammary amyloidosis are exceedingly rare entities. This report describes the case of a woman with long standing Sjögren’s syndrome presenting with asymptomatic MZL of the breast showing plasmacytic differentiation, associated with local ductular amyloidosis. The lesion was discovered incidentally in breast tissue resected for microcalcifications. Immunohistochemistry revealed κ light chain restriction, supporting the neoplastic nature of the infiltrate. A retrospective molecular study of the salivary gland biopsy showed a B cell clone. This is the first report of the association of human mammary ductular amyloidosis with cartwheel shaped material identical to corpora amylacea, usually seen in brain, lung, and prostate, but unknown in the human breast. The excellent outcome without treatment seen in this patient further emphasises the need to distinguish between MZL with plasmacytic differentiation and extramedullary plasmacytoma.
Endurance and Resistance Training in Radically Treated Respiratory Cancer patients: A Pilot Study

Introduction. Respiratory cancer and its treatment are known to contribute to muscle weakness and functional impairment. Aim. To assess the effects of rehabilitation in patients with respiratory cancer. Methods. Radically treated respiratory cancer patients were included in a 12-week multidisciplinary rehabilitation program. Results. 16 patients (age: 61 ± 7 years; FEV1: 57 ± 16% pred.) showed a reduced exercise tolerance (VO2max: 56 ± 15% pred.; 6 MWD: 67 ± 11% pred.), muscle force (PImax: 54 ± 22% pred.; QF: 67 ± 16% pred.), and quality of life (CRDQd: 17 ± 5 points; CRDQf: 16 ± 5 points). Exercise tolerance, muscle force, and quality of life improved significantly after rehabilitation. Conclusion. Radically treated patients with respiratory cancer have a decreased exercise capacity, muscle force, and quality of life. 12 weeks of rehabilitation leads to a significant improvement in exercise capacity, respiratory muscle force, and quality of life.
Iterative frequency estimation by interpolation on Fourier coefficients

The estimation of the frequency of a complex exponential is a problem that is relevant to a large number of fields. In this paper, we propose and analyze two new frequency estimators that interpolate on the Fourier coefficients of the received signal samples. The estimators are shown to achieve identical asymptotic performances. They are asymptotically unbiased and normally distributed with a variance that is only 1.0147 times the asymptotic Crame/spl acute/r-Rao bound (ACRB) uniformly over the frequency estimation range.
Smoking Among Young Urban Malaysian Women and its Risk Factors

This study was conducted to measure the prevalence of cigarette smoking and to determine the individual, family, and environmental factors associated with smoking among young urban women. A cross-sectional study through self-administered questionnaire was conducted on female students enrolled in private higher learning institutions in Kuala Lumpur and Selangor, Malaysia, between July and October 2005. Analysis on 408 respondents showed that current smoker prevalence rate was 18.6%. Adjusted analyses showed significant association between smoking and individual factors, which are the importance of slim image, average monthly allowance, and car ownership. For family factors, analyses showed significant association between smoking and parental marital status and smoking status of male siblings. Strong associations were seen between female smoking and environmental factors, such as having more smoker friends, having smokers as best friends, keeping cigarette-brand items, being offered free cigarette, and perceiving female smoking as normal. The identified risk factors could be used to develop more effective prevention programs to overcome smoking among young urban women.
Changes of resting cerebral activities in subacute ischemic stroke patients

This study aimed to detect the difference in resting cerebral activities between ischemic stroke patients and healthy participants, define the abnormal site, and provide new evidence for pathological mechanisms, clinical diagnosis, prognosis prediction and efficacy evaluation of ischemic stroke. At present, the majority of functional magnetic resonance imaging studies focus on the motor dysfunction and the acute stage of ischemic stroke. This study recruited 15 right-handed ischemic stroke patients at subacute stage (15 days to 11.5 weeks) and 15 age-matched healthy participants. A resting-state functional magnetic resonance imaging scan was performed on each subject to detect cerebral activity. Regional homogeneity analysis was used to investigate the difference in cerebral activities between ischemic stroke patients and healthy participants. The results showed that the ischemic stroke patients had lower regional homogeneity in anterior cingulate and left cerebrum and higher regional homogeneity in cerebellum, left precuneus and left frontal lobe, compared with healthy participants. The experimental findings demonstrate that the areas in which regional homogeneity was different between ischemic stroke patients and healthy participants are in the cerebellum, left precuneus, left triangle inferior frontal gyrus, left inferior temporal gyrus and anterior cingulate. These locations, related to the motor, sensory and emotion areas, are likely potential targets for the neural regeneration of subacute ischemic stroke patients.
Evaluation of the 15N-isotope dilution technique for determining the recovery of endogenous protein in ileal digesta of pigs: effect of the pattern of blood sampling, precursor pools, and isotope dilution technique.

The 15N-enrichments (atom percentage excess) were determined in the plasma free amino acids of blood samples taken at the time of feeding and in samples taken hourly and pooled over 12 h, as well as in ileal digesta, crude mucin, and bacteria collected at the distal ileum of pigs fed barley while continuously administered [15N]leucine intravenously. The branched-chain amino acids were the only indispensable amino acids to exhibit incorporation of 15N (P < .05). All dispensable amino acids exhibited some incorporation. Enrichments in free leucine and alanine were higher (P < .02) in blood samples taken at the time of feeding, compared to those in pooled blood samples, resulting in an underestimation of the endogenous ileal recoveries of these amino acids. Enrichments in amino acids in crude mucin were usually similar to those in pooled plasma samples, providing some support for the use of plasma free amino acids to estimate enrichments in endogenous amino acids in ileal digesta. Enrichments in bacteria were not different (P > .05) from those in ileal digesta. The recoveries of endogenous amino acids in ileal digesta determined with the [15N]leucine and 15N-amino acid dilution techniques demonstrate the overestimation of these criteria with the 15N-isotope dilution technique, applied in its current form, and suggest that modifications in the composition of endogenous protein can occur when pigs are fed protein-containing diets. These study supports the use of 15N-isotope dilution techniques, with modifications, for determining the recovery of endogenous protein in ileal digesta of pigs fed protein-containing diets.

Unveiling the invisible learning from unpaid household work: Chinese immigrants' perspective

This paper examines unpaid household work and the informal learning involved in it, with the focus on new Chinese immigrants in Canada. The data used in this paper are drawn from two sources: the 2004 Canadian Survey on Work and Lifelong Learning , and in-depth interviews with 20 new Chinese immigrants in Toronto, Canada. The survey section examines data on informal learning through housework and general interest-related activities, with a focus on the comparison of three groups of Canadians: Canadian-born, other immigrants, and Chinese immigrants. The survey data explore how gender, immigration, and ethnicity influence the informal learning involved in performing the unpaid household activities. The interview section explores the impact of cross-cultural immigration on household work among new Chinese immigrants and the knowledge and skills they acquired through such work. Through the analysis of both the quantitative and qualitative data, the author argues that unpaid household work and the learning involved in it are not only gendered, but also classed, and that household work is constantly changing throughout one’s lifetime; thus, informal learning involved in such work is lifelong as well as lifewide. Resume Cet article se penche sur le travail domestique non remunere et l’apprentissage informel qui s’y rattache, plus specifiquement aupres d’immigrants chinois nouvellement arrives au Canada. Les donnees utilisees proviennent de deux sources : un sondage pan-canadien mene en 2004 par le reseau Work and Lifelong Learning (WALL) et des entrevues menees aupres de vingt immigrants chinois, nouvellement etablis a Toronto, Canada. La section qui se rapporte au sondage de WALL examine des donnees relatives a l’apprentissage informel par le travail domestique, et des activites d’interet general, aupres de trois groupes differents : canadiens de souche, autres immigrants et immigrants chinois. Les donnees de WALL s’attardent a la facon dont le sexe, l’immigration et la race influencent l’apprentissage informel implique dans le travail domestique non remunere. La section qui se rapporte aux entrevues mesure l’impact de l’immigration interculturelle sur le travail domestique chez les nouveaux immigrants chinois; elle fait aussi etat des connaissances et competences acquises par l’entremise de ce travail. A travers l’analyse de donnees qualitatives et quantitatives, l’auteur argumente que le travail domestique non remunere et l’apprentissage informel qui s’y rattache ne sont non seulement lies au sexe, mais aussi a la classe sociale, et que le travail domestique est en constant changement tout au long de la vie. Par consequent l’apprentissage informel qui s’y rattache se prolonge tout au long et dans toutes les facettes de la vie.
Direct Economic Burden of Chronic Hepatitis C Virus in a United States Managed Care Population

Goals and Background To estimate all-cause and disease-related resource utilization and costs among managed care enrollees with chronic hepatitis C virus (HCV). Study A large United States claims database was analyzed (1/1/2002 to 12/31/2006). Inclusion criteria were: diagnosis of chronic HCV; no hepatitis B diagnoses; ≥6 and ≥12 months of continuous plan enrollment prediagnosis and postdiagnosis, respectively. Use and costs of medical services and prescription drugs over a 12-month period postdiagnosis were evaluated. Outcomes were assessed in controls without HCV matched (1:1) on age, sex, and plan enrollment. All cost estimates were generated using multivariate generalized linear models to adjust for additional covariates and skewness common in health care cost data. Results Of the 20,662 patients who met all inclusion criteria, mean age was 49 years; 61% were male. Adjusted all-cause costs were $20,961 per HCV patient, compared with $5451 per control (P<0.0001). Hospitalization occurred in 24% of HCV patients compared with 7% of controls (P<0.0001). Mean inpatient costs were $5892 and $1159 per patient, respectively (P<0.0001). Patients with HCV had higher prescription costs compared with controls ($6191 vs. $1315; P<0.0001). At $6864 per patient, disease-related costs were nearly one-third of all costs in patients with HCV, which exceeded all-cause costs among controls by 26% (P<0.0001). Conclusions Chronic HCV is a costly disease to managed care organizations. Disease-related costs in HCV exceed all-cause costs in demographically matched controls. Increased efforts in HCV screening and early treatment, particularly before progression to liver cirrhosis, may lead to long-term cost savings in HCV management for managed care systems.
Is 8 weeks of side-alternating whole-body vibration a safe and acceptable modality to improve functional performance in multiple sclerosis?

Purpose: To examine whether an 8-week period of side-alternating whole-body vibration (WBV) exercise is an acceptable and effective exercise intervention to improve and maintain functional performance in multiple sclerosis people. Methods: A total of 15 participants with MS (11 women [mean age 50.2 ± 6.9 years; body mass 65.7 ± 19.2 kg; height 165.3 ± 6.1 cm; EDSS 3.5 ± 0.9] and 4 males [mean age 50.5 ± 5.2 years; body mass 85.3 ± 16.0 kg; height 175.3 ± 3.2 cm; EDSS 3.4 ± 0.5]) were selected for this study. Quality of life, timed up-and-go, functional reach, standing balance and 10-m walk test were performed prior to and after 4 and 8 weeks of vibration exercise, and 2 weeks after cessation of vibration exercise. Results: There was no evidence of vibration exercise producing any anxiety or discomfort. Compared with baseline measurements, the 10-m walk test showed significant improvements in 2, 8 and 10 m times at 8 week (p < 0.05) and 2 week post-vibration (p < 0.05). Timed up-and-go demonstrated a significant and positive time effect (p < 0.05). Standing balance showed significant improvements from baseline, at 4- (p < 0.05) and 2-weeks post-vibration (p < 0.05). Conclusion: This is the first study to investigate side-alternating WBV as an exercise training modality for MS people. From an active MS population, this study has shown that WBV training not only improved the standing balance and walking time but there were also no adverse effects from using this modality. Implications for Rehabilitation Muscle weakness and fatigue are reported by most patients with multiple sclerosis (MS). Whole-body vibration (WBV) has gained popularity as an exercise modality in participants with either normal or compromised health. WBV is a safe and effective exercise intervention for persons with MS to improve and maintain functional ability and quality of life.
