Information Needs and Information-Seeking Behavior: A Survey of College Faculty at Bahawalpur

The purpose of this paper is to determine the information needs and information-seeking behavior of college faculty (i.e. teachers and administrators) at Bahawalpur City. A survey was used for the study. The results of the study reveal that current services rendered by the college libraries are not fulfilling the information needs of college faculty to great extent. They search their personal collection in case of urgent need of information instead of visiting the library. Furthermore they mostly rely on informal sources of information. Information technology has affected their information seeking behavior and made information seeking process easier.
Determination of acute leukemia lineage with new morphologic parameters available in the complete blood cell count.

GOALS Cell population data (CPD) are new morphologic parameters including volume, conductivity, and five light scattering characteristics used for leukocyte classification by an automated hematology analyzer, the UniCel DxH 800. We developed a discriminating CPD model to predict the leukemia lineage during routine complete blood cell count (CBC). PROCEDURES We analyzed the CPD of 405 blood samples containing more than 10% blasts that were randomly divided into test and validation sets. With the test set, we produced a model for categorizing acute lymphoblastic leukemia (ALL) or acute promyelocytic leukemia (APL), using ranges of the CPD and regarding the remainder as non-APL acute myeloid leukemia. We verified these models against the validation set. RESULTS In the test set, we formulated a 21-parameter model which identified 43 of 47 ALL cases (91.5% sensitivity) and ruled out 151 of 156 other leukemia cases (96.8% specificity), and a 13-parameter model which distinguished all 10 APL cases (100% sensitivity) and excluded 193 other leukemia cases (100% specificity). In the validation set, the ALL model showed 85.1% sensitivity and 94.2% specificity, and the APL model 100% sensitivity and 100% specificity. CONCLUSIONS This study demonstrated a new solution for predicting blast lineage using the CPD on a CBC and leukocyte differential.
Social Comparison in Physical Education: An Examination of the Relationship between Two Frames of Reference and Engagement, Disaffection, and Physical Self-Concept.

Drawing from theory and research into social comparison processes, the present study sought to determine children's motives for comparison in addition to the coexistence of class and individual comparisons in school physical education. The main and interactive effects of these types of comparisons were examined in relation to pupils’ physical self-concept, as well as self-reported behavioral engagement and disaffection in class. In total, 545 children (Mage = 13.89 years, SD = 1.57 years) from two schools in England completed the questionnaire. Moderated hierarchical regression analysis demonstrated that the higher a child's perception of his or her ability was compared with his or her classmates, the greater the level of engagement and physical self-concept and the lower the level of disaffection. Interaction analysis showed that when perceived ability with reference to the class was low, a downward comparison with an individual enhanced engagement, but this was not the case when perceived ability was high. Findings suggest that further research into social comparison processes in this setting is warranted.
Antithrombotic and Hemorrhagic Effects of DX-9065a, a Direct and Selective Factor Xa Inhibitor: Comparison with a Direct Thrombin Inhibitor and Antithrombin Ill-Dependent Anticoagulants

Summary (+)-2S-2-[4-[[(3S)-l-acetimidoyl-3- pyrrolidinyl]oxy]phenyl]-3-[7-amidino-2-naphthyl]propanoic acid hydrochloride pentahydrate (DX- 9065a) is an antithrombin III (AT III)-independent and selective inhibitor of activated blood coagulation factor X (FXa). The aim of the present study was to compare the antithrombotic and hemorrhagic effects of DX-9065a with a direct thrombin inhibitor and AT Ill-dependent anticoagulants in rat models of thrombosis and bleeding. Rats were administered intravenously DX-9065a (0.1-1 mg/kg/h), argatroban (0.1-1 mg/k/h), low molecular weight heparin (25-100 anti- XaU/kg/h), unfractionated heparin (25-100 anti-XaU/kg/h) or Orgaran (30-300 anti-XaU/kg/h) for 1 h. DX-9065a dose-dependently inhibited both thrombus formation and elevation in plasma thrombin-AT III complex (TAT) level in a copper wire-inserted arteriovenous (AV) shunt model in rats. The dose required for 50% inhibition of thrombus formation was 0.27 mg/kg/h. DX-9065a did not prolong transection bleeding time up to 7.78 mg/kg/h. Argatroban and AT Ill-dependent anticoagulants also inhibited both thrombus formation and TAT elevation, but prolonged bleeding time at a slightly higher dose than the effective dose. These results suggest that direct and selective inhibition of factor Xa by DX-9065a is preferable for the treatment of thrombosis in the aspect of lack of compromising primary hemostasis.
Untaxed Cash Work: Feeding Mouths, Lining Wallets

Method for curing UV-curable silicone compositions, characterized by the formation of cured silicone, having a low-tack surface that is harder than the interior, by exposing an ultraviolet-curable silicone composition to ultraviolet radiation at a ratio of the exposure dose for wavelengths of 200 to 280 nm (excluding 280 nm) to the exposure dose for wavelengths of 280 to 400 nm of 0.5 to 10.0.
La distinction : addendum statistique.

The aim of this study is twofold: first, to assess the statistical significance of the data used by Pierre Bourdieu in Distinction; second, to test the hypothesis that the volume of capital (i.e., the global amount of capital) allows for a finer discrimination of dispositional differences than the composition of capital (i.e., the respective weight of the different types of capital in the global amount of capital). To these ends, five data samples were submitted to bilateral between-proportion comparison tests. The findings (1) reveal that about two-thirds of the differences reported by P. Bourdieu are significant and (2) support the view that the volume of capital prevails over its composition. Cette etude poursuit deux objectifs : etablir, d'une part, la significativite statistique des donnees ayant servi de base empirique au modele que Pierre Bourdieu propose dans La distinction ; mettre a l’epreuve, d'autre part, l'hypothese selon laquelle le volume de capital (i.e. la quantite globale de capital) constitue, en matiere de differenciation dispositionnelle, une variable plus determinante que la structure du capital (i.e. le poids respectif des differents types de capital au sein du volume global de capital). A cette double fin, les donnees relatives a cinq echantillons sont soumises a des tests de comparaison bilaterale de proportions independantes. Les resultats obtenus (1) revelent que pres des deux tiers des differences observees par P. Bourdieu sont significatives et (2) soutiennent l'hypothese de la preponderance du volume de capital sur sa structure.
Image denoising using contextual modeling of curvelet coefficients

We propose an image denoising method which takes curvelet domain inter-scale, inter-location and inter-orientation dependencies into account in a maximum a posteriori labeling of the curvelet coefficients of a noisy image. The rationale is that generalized neighborhoods of curvelet coefficients contain more reliable information on the true image than individual coefficients. Based on the labeling of coefficients and their magnitudes, a smooth thresholding functional produces denoised coefficients from which the denoised image is reconstructed. We also outline a faster approach to labeling and thresholding, relying on contextual comparisons of coefficients. Quantitative and qualitative evaluations on natural and X-ray images show that our method outperforms related multiscale approaches and compares favorably to the state-of-art BM3D method on X-ray data while executing faster.
Flight control of fruit flies: dynamic response to optic flow and headwind

ABSTRACT Insects are magnificent fliers that are capable of performing many complex tasks such as speed regulation, smooth landings and collision avoidance, even though their computational abilities are limited by their small brain. To investigate how flying insects respond to changes in wind speed and surrounding optic flow, the open-loop sensorimotor response of female Queensland fruit flies (Bactrocera tryoni) was examined. A total of 136 flies were exposed to stimuli comprising sinusoidally varying optic flow and air flow (simulating forward movement) under tethered conditions in a virtual reality arena. Two responses were measured: the thrust and the abdomen pitch. The dynamics of the responses to optic flow and air flow were measured at various frequencies, and modelled as a multicompartment linear system, which accurately captured the behavioural responses of the fruit flies. The results indicate that these two behavioural responses are concurrently sensitive to changes of optic flow as well as wind. The abdomen pitch showed a streamlining response, where the abdomen was raised higher as the magnitude of either stimulus was increased. The thrust, in contrast, exhibited a counter-phase response where maximum thrust occurred when the optic flow or wind flow was at a minimum, indicating that the flies were attempting to maintain an ideal flight speed. When the changes in the wind and optic flow were in phase (i.e. did not contradict each other), the net responses (thrust and abdomen pitch) were well approximated by an equally weighted sum of the responses to the individual stimuli. However, when the optic flow and wind stimuli were presented in counterphase, the flies seemed to respond to only one stimulus or the other, demonstrating a form of ‘selective attention’. Summary: Measurement and characterisation of the dynamic flight response of fruit flies reveal that their flight controller weighs visual and wind stimuli approximately equally, to produce flight thrust and adjust the pitch of the abdomen.
What’s New in Femoroacetabular Impingement Surgery

Context: Femoroacetabular impingement (FAI) has been described as a common cause of hip pain in young adults. This leads to abnormal hip joint mechanics and contact pressures. The associated pathomechanics can lead to the development of early osteoarthritis. Better understanding of the anatomy and pathophysiology, biomechanics, and diagnostic and therapeutic advances has led to improved clinical outcomes. A growing body of evidence has set the foundation for future progress in the treatment of this commonly encountered condition. Evidence Acquisition: The PubMed database was searched for English-language articles pertaining to FAI over the past 15 years (1998-2013). Study Design: Retrospective literature review. Level of Evidence: Level 4. Results: The authors evaluated and discussed the current evidence regarding the anatomy, physiology, biomechanics, imaging, and clinical outcomes of surgical intervention for FAI. Based on this information, future directions for improving the diagnosis and management of FAI are proposed. Conclusion: There remains a diverse approach to the diagnosis and management of cam- and/or pincer-type FAI. Recent advances in clinical diagnosis, imaging, indications, and arthroscopic techniques have led to improved outcomes and have set the foundation for future progress in the management of this condition.

Swahili Borrowings from English

Opening Paragraph Swahili is, by origin, a Bantu language which was strongly influenced by Arabic. In the course of time Swahili has borrowed words from a variety of languages. During the last thirty or forty years it is not surprising to find that Swahili has continued to enrich its vocabulary, more particularly from English. Résumé EMPRUNTS DE L'ANGLAIS PAR LE SWAHILI Le swahili a été fortement influencé par la langue arabe et a emprunté des mots de plusieurs autres langues, et plus particulièrement au cours de ces dernières années, de l'anglais. Naturellement, de tels mots d'emprunt sont plus nombreux dans les domaines où le contact avec la civilisation européenne a été le plus étendu. L'auteur donne de nombreux exemples de mots concernant le transport, la médecine, les sports, les écoles, dont les expressions anglaises ont été incorporées dans le swahili. Quelques africanistes ont exprimé l'opinion que l'emprunt de mots anglais par une langue africaine est à regretter, mais tous les mots cités comme exemples dans cet article ont été adoptés par les Africains eux-mêmes et il est probable que leur emploi se généralisera davantage. Dans une langue vivante une évolution et un enrichissement semblables sont inévitables et méritent d'être enregistrés.
Central and Sensory Contributions to the Activation and Organization of Muscle Synergies during Natural Motor Behaviors

Previous studies have suggested that the motor system may simplify control by combining a small number of muscle synergies represented as activation profiles across a set of muscles. The role of sensory feedback in the activation and organization of synergies has remained an open question. Here, we assess to what extent the motor system relies on centrally organized synergies activated by spinal and/or supraspinal commands to generate motor outputs by analyzing electromyographic (EMG) signals collected from 13 hindlimb muscles of the bullfrog during swimming and jumping, before and after deafferentation. We first established that, for both behaviors, the intact and deafferented data sets possess low and similar dimensionalities. Subsequently, we used a novel reformulation of the non-negative matrix factorization algorithm to simultaneously search for synergies shared by, and synergies specific to, the intact and deafferented data sets. Most muscle synergies were identified as shared synergies, suggesting that EMGs of locomotor behaviors are generated primarily by centrally organized synergies. Both the amplitude and temporal patterns of the activation coefficients of most shared synergies, however, were altered by deafferentation, suggesting that sensory inflow modulates activation of those centrally organized synergies. For most synergies, effects of deafferentation on the activation coefficients were not consistent across frogs, indicating substantial interanimal variability of feedback actions. We speculate that sensory feedback might adapt recruitment of muscle synergies to behavioral constraints, and the few synergies specific to the intact or deafferented states might represent afferent-specific modules or feedback reorganization of spinal neuronal networks.
Dialogical Demand: Discursive Position Repertoires for a Local and Global UK Sex Industry

The increasing incidence of ‘trafficking’ has added an incontestably disturbing dimension to the contestable nature of a ‘non-trafficked’ UK sex industry. Men who buy sex remain under-researched, though some studies have indicated ambivalence within men's attitudes. This study combines a critical discursive psychology in support of dialogical self theory. Secondary data, from prominent UK media resources, were analysed using Edley's (2001) method of combining ‘interpretative repertoires’, ‘ideological dilemmas’ and ‘subject positions’. Contrasting discursive practices indicative of wider ideological conflict were found. Discursive concepts were ‘mapped’ onto Hermans and Hermans-Konopka's (2010) ‘I-positions’ to explore how these potentially dilemmatic positions might be understood in terms of identity production. The function of ‘uncertainty’, particularly salient with the increasing complexity of globalisation, was considered a factor in how men's identities might be limited by the current discursive space. A ‘dialogical’ model of self is introduced as a framework for understanding how men who buy sex might take up new, inclusive, positions. A corollary is reflected upon; that researchers, activists and buyers alike, who remain ideologically inflexible, may be sustaining the conditions for coercion through their contribution to the discursive conflict. The synthesis of discursive and dialogical analytical tools is recommended for investigating the production of selves in contested spaces.
PERCEIVED AGEING AND ELDERS HEALTH; AN ANTHROPOLOGICAL STUDY OF OLDER PERSONS OF RAWALPINDI

ABSTRACT… Culture and society always an important factor that contributed to build the stereo types rather positive and negative that affect our everyday life. As with other social issues ageing is also effected the cultural and societal stereo types. Concept of old age was not the only creation of old age rather it was started when they were young and strong concepts were developed and concreted with the passage of time as he get older and older. Objective: (1) To explore what Older Persons (OPs) perceived about old age. (2) To find the cross relationship between their concept of old age and their disease status. Methodology: Statistically calculated sample of 384 OPs were randomly interviewed by taking their verbal consent after introducing them about objective of study. Structured questionnaire was developed for data collection purposes. Data was entered and analyzed in SPSS. Results: among 384 respondents 31.3% perceived old age as illness and disease, 15.9% consider it stress and depression, 25.5% were of the view that old age is phase of social isolation and ignorance, increased dependency was also recorded 9.1% and less social participation as 11.7%. Hypertension was reported by 8.1% of the study respondents, Heart problem in 12.8% cases and Diabetes in 15.1% cases.
Partisan News and Political Participation: Exploring Mediated Relationships

This study examines mediators of the relationship between news consumption and political participation in the contemporary news environment. We test the differential effects exerted by pro- and counter-attitudinal news compared with balanced news on intended participation. Our primary objective is to model three paths that may link news exposure and participation: cognitive (i.e., perceived issue understanding), affective (i.e., emotions evoked by a news story), and attitudinal (i.e., attitude strength). We compare these paths across four issues, testing which is strongest. Relying on a large survey-based experiment on a representative sample of the American population (N = 2,300), we find that pro-attitudinal exposure increases intended participation relative to balanced news exposure, while the effects of counter-attitudinal news do not differ from those exerted by balanced news. Issue understanding, anger, positive emotions, and attitude strength all mediate the relationship between pro-attitudinal exposure and intended participation, with the route via attitude strength being strongest. These effects do not depend on whether exposure is self-selected or experimentally assigned.
Analyzing Password Strength

Password authentication is still the most used authentication mechanism in today’s computer systems. In most systems, the password is set by the user and must adhere to certain password requirements. Additionally, password checkers rank the strength of a password to give the user an indication of how secure their password is. In this paper, we take a look at a large database of user chosen passwords to determine the current state of affairs. In the end, we extract a model from the database and provide our own password checker which ranks passwords in various ways. We ran this checker against our dataset which shows that over 90% of the passwords is highly insecure.
Detection of a Novel Astrovirus in Brain Tissue of Mink Suffering from Shaking Mink Syndrome by Use of Viral Metagenomics

ABSTRACT In 2000, farmed mink kits in Denmark were affected by a neurological disorder. The characteristic clinical signs included shaking, staggering gait, and ataxia. The disease, given the name shaking mink syndrome, was reproduced by the inoculation of brain homogenate from affected mink kits into healthy ones. However, the etiology remained unknown despite intensive efforts. In this study, random amplification and large-scale sequencing were used, and an astrovirus was detected in the brain tissue of three experimentally infected mink kits. This virus also was found in the brain of three mink kits naturally displaying the disease but not in the six healthy animals investigated. The complete coding region of the detected astrovirus was sequenced and compared to those of both a mink astrovirus associated with preweaning diarrhea and to a recently discovered human astrovirus associated with a case of encephalitis in a boy with x-linked agammaglobulinemia. The identities were 80.4 and 52.3%, respectively, showing that the virus described in this study was more similar to the preweaning diarrhea mink astrovirus. For the nonstructural coding regions the sequence identity was around 90% compared to that of the astrovirus, which is associated with preweaning diarrhea in mink. The region coding for the structural protein was more diverse, showing only 67% sequence identity. This finding is of interest not only because the detected virus may be the etiological agent of the shaking mink syndrome but also because this is one of the first descriptions of an astrovirus found in the central nervous system of animals.
Motivational Needs of Middle Grade Students Enrolled in Agricultural Education in Georgia.

The purpose of this study was to examine the motivational needs of middle grade (grade 7-8) students who enroll in Agricultural Education classes in Georgia. McClelland=s motivational needs theory served as the framework for the study. The data determined that agricultural students had a higher need for achievement than for affiliating or power and that no differences existed between FFA members and non FFA members. The study also determined that female agricultural education students had a higher need for affiliation and power than male students. No differences were found in the need for achievement, affiliation or power when students were grouped by grade or geographic location. African-American students had a higher need for achievement and power than students in all other ethnic categories.
Set invariance under output feedback: a set-dynamics approach

The article offers a framework to define and analyse the notion of invariance with respect to output feedback under non-parametric disturbances. The motivation is that the straightforward generalisation of the definition of invariance under state feedback to the output feedback framework, namely relying only on feedback from the output, does not yield a useful notion. Our model follows standard feedback invariance considerations with, however, a crucial modification that is needed when only an observation of the state, rather than the state itself, is available. The model incorporates information gathered by the controller during the process; this is in similarity with the observer-based dynamics model; however our framework represents the information within a set dynamics. The evolution of the resulting information sets determines invariant sets and attractors of the state dynamics. The framework in this article is discrete-time control systems. We offer an analysis of the notion with results on existence of, and convergence to, output feedback invariant sets; illustrative examples related to potentially practical feedback rules are exhibited.
