A Comparison of Practitioners' Perceptions about Professional Identity at Higher Secondary Level.

The study was conducted to compare practitioners’ perception about professional identity at higher secondary level. The purpose of the study was to equate practitioners’ perception about three components of professional identity (1) Who am I? (2) What is my role? (3) How I should be? The population of the study comprised male and female practitioners teaching at higher secondary level. Data was collected from 633 public and private sector college practitioners through disproportionate stratified sampling technique. Major findings of study were that there was no significant difference in professional identity of public and private sector practitioners; however, private sector college practitioners were found more concerned about improving themselves. It was concluded that the teachers from both sectors had same views about their description as a teachers and their role as a teacher but teachers of private sector were more concerned about how they should be. It was suggested that practitioners at higher secondary may be provided training for enhancing professional identity through collaboration with universities and international donor agencies which are interested to raise the quality of education in Pakistan. It can be made mandatory to promote the college teachers to next grade within training courses and professional development programs.

Very small, individual polymeric microspheres with very precise size and a wide variation in monomer type and properties are produced by deploying a precisely formed liquid monomer droplet, suitably an acrylic compound such as hydroxyethyl methacrylate into a containerless environment. The droplet which assumes a spheroid shape is subjected to polymerizing radiation such as ultraviolet or gamma radiation as it travels through the environment. Polymeric microspheres having precise diameters varying no more than plus or minus 5 percent from an average size are recovered. Many types of fillers including magnetic fillers may be dispersed in the liquid droplet.
Comparative Evaluation of Anxiety Level during the Conventional Dental Procedures with and without Audiovisual Distraction Eyeglasses in Pediatric Dental Patients

Background: Dental anxiety denotes a state of apprehension that something dreadful is going to happen in relation to dental treatment, and it is coupled with a sense of losing control. High levels of anxiety prevent a patient from cooperating fully with their dentist and limit the effectiveness of the dental treatment. In recent years, research in the dental operatory has proven the value of psychological techniques in preparing children for and managing children during dental treatment. Distraction has been examined in a variety of medical and dental settings as a relatively easy, inexpensive, and simple approach to reducing distress and disruptive behavior in children. The purpose of this study is to evaluate the effectiveness of the audiovisual distraction (AVD) eyeglasses in reduction of anxiety during conventional dental procedures in pediatric dental patients. Materials and Methods: Study comprised 40 healthy children between 6 and 10 years old visiting Dr. D.Y. Patil Dental College and Hospital, Pimpri, Pune, for the dental treatment with Frankl’s behavior rating scale score 3 and 4. They were divided into two groups; each group having 20 patients each. Group I having 20 subjects wearing AVD eyeglasses and Group II having 20 subjects without wearing AVD eyeglasses. Three procedures including oral prophylaxis, restorative treatment, and pulpectomy procedures were done on each subject during three subsequent visits or more. Scores obtained on the basis of Wong-Bakers Faces Pain Rating Scale, Visual Analog Scale (VAS) and pulse oximeter were compared, evaluated, and tabulated. Results: It was found that anxiety reduction was seen via WongBakers Pain Rating Score in Group A in children wearing AV eyeglasses being statistically significant in oral prophylaxis (P < 0.05), restoration (P < 0.05), and pulpectomy/root canal treatment (RCT) (P < 0.005) as compared to Group B which is children without wearing AV eyeglasses. Anxiety reduction was seen via VAS in Group A in children wearing AV eyeglasses being statistically significant in oral prophylaxis (P < 0.05), restoration (P < 0.001), and pulpectomy/RCT (P < 0.005) as compared to Group B which is children without wearing AV eyeglasses. Anxiety reduction was seen via pulse oximeter in Group A in children wearing AV eyeglasses being statistically significant in restoration (P < 0.01) and not statistically significant in oral prophylaxis (P > 0.05) and pulpectomy/RCT (P > 0.05) as compared to Group B which is children without wearing AV
SOCIOPART : Hopping Based Partitions by Vivek Mahajan

Online social networking has become a phenomenon in the last few years. The growing usage of social networks has put the vendors under a lot of pressure to efficiently process the users queries. In social networks like orkut, most of the queries access the immediate neighbors of the current node and neighbors of its neighbors. Existing graph partitioning approaches focus on reducing the number of inter server links, neglecting the query patterns. Our algorithm focuses on partitioning the graph so as to minimize the number of servers to be accessed in order to process a query. Our results show that the proposed algorithm gives useful partitioning of social networks, thereby reducing inter server accesses.
Blood Vessels Segmentation in Retinal Fundus Image using Hybrid Method of Frangi Filter, Otsu Thresholding and Morphology

Diagnosis of computer-based retinopathic hypertension is done by analyzing of retinal images. The analysis is carried out through various stages, one of which is blood vessel segmentation in retinal images. Vascular segmentation of the retina is a complex problem. This is caused by non-uniform lighting, contrast variations and the presence of abnormalities due to disease. This makes segmentation not successful if it only relies on one method. The aims of this study to segment blood vessels in retinal images. The method used is divided into three stages, namely preprocessing, segmentation and testing. The first stage, preprocessing, is to improve image quality with the CLAHE method and the median filter on the green channel image. The second stage, segmenting using a number of methods, namely, frangi filter, 2D-convolution filtering, median filtering, otsu's thresholding, morphology operation, and background subtraction. The last step is testing the system using the DRIVE and STARE dataset. The test results obtained sensitivity 91.187% performance parameters, 86.896% specificity, and area under the curve (AUC) 89.041%. Referring to the performance produced, the proposed model can be used as an alternative for blood vessel segmentation of retinal images.
Population-Based Tuberculosis Disease Prevalence Survey in Ghana: The Role and Lessons Learnt from the Laboratory

Background: Bacteriologically-confirmed tuberculosis (TB) cases used in calculating TB prevalence in a country are obtained through laboratory examination of sputum specimens. Objective: This article describes laboratory processing of specimens, results overview, conclusions and key lessons learnt from the perspective of laboratory personnel involved in the conduct of TB disease prevalence survey in Ghana in 2013. Methods: Symptoms screening and Chest X-ray suggestive of TB were used to select participants who produced sputum to confirm TB cases using microscopy, culture and Xpert® MTB/RIF assay (GeneXpert). Results: A total of 15,935 single and paired sputum specimens were received from eligible participants. About half of Ziehl-Nielsen (129/263) and Auramine O (122/246) stained smear positives were scanty positive. Culture positivity rate for Mycobacterium tuberculosis complex was 266/14,994 (1.7%) and 100/15,179 (0.7%) in Mycobacterial Growth Indicator Tube (MGIT) and Lowenstein-Jensen (LJ) media respectively; while non-tuberculous mycobacterium was 294/14,994 (1.96%) and 167/15,179 (1.1%). Total contamination rates in MGIT (5.4%) were higher than in LJ (1.7%). Prevalence of smear positive TB and bacteriologically confirmed TB among adult population (≥15 years) was estimated at 111 (95% CI: 76 - 145) and 356 (95% CI: 288 - 425) per 100,000 population respectively. Conclusions and Lessons Learnt: Direct supervision of specimen collection by well-trained laboratory personnel, timely transportation of specimens from field to laboratory, prompt specimen processing and use of electronic data management systems are essential for a reliable TB disease prevalence survey data. More importantly, strengthening human and logistical capacity of the laboratory must be of utmost priority.
Real-Time Induced Seismicity Forecasting and Risk Management Utilizing Research-grade Seismic Catalogs

Practical management of induced seismicity risk and effective mitigation approaches are crucial to oil and gas operations. Effective risk management procedures benefit from an accurate forecast of the largest potential magnitude event in near real-time, allowing the adjustment of operational parameters to reduce the probability of a felt or damaging event. Many models have been proposed to estimate the magnitude of the strongest possible event. Some of these models rely solely on statistics of recorded seismicity while others account for the relation of event size with operational parameters. There are also models that relate the maximum magnitude with existing geological and tectonic conditions.
Emotions, Risk Attitudes, and Patience

Previous work has shown that preferences are not always stable across time, but surprisingly little is known about the reasons for this instability. I examine whether variation in people’s emotions over time predicts changes in preferences. Using a large panel data set, I ﬁnd that within-person changes in happiness, anger, and fear have substantial effects on risk attitudes and patience. Robustness checks indicate a limited role of alternative explanations. I further address potential endogeneity concerns by exploiting information about the death of a parent or child. This identiﬁcation strategy conﬁrms a large causal impact of emotions on preferences.
Evolution of turbulent transport and plasma energy confinement time in tokamaks in regimes with additional heating : simulations and comparison with T-10 experiments

The paper continues our previous theoretical study [1-4] of low-frequency (LF) turbulent convection and the resulting anomalous cross-field transport in tokamak core plasmas in various quasi-steady and transient regimes of plasma confinement and heating. Relatively simple adiabatically-reduced MHD-like model of nonlinear plasma convection has been proposed and used in our simulations. The total (anomalous) radial magnetic-surfaceaveraged heat fluxes both for electron and ion components consist of background and turbulent parts: . Similarly the surface-averaged particle flux Γ turb i e bg i e tot i e q q q ) , ( ) , ( ) , ( + = tot also consists of background and turbulent fluxes: Γtot = Γbg + Γturb. Typically, we associate the background fluxes with some kind of neoclassical diffusive fluxes. Contrary to the background fluxes the turbulent fluxes are non-diffusive and are calculated using the direct self-consistent solution of nonlinear equations for fluctuations of turbulent velocity, pressure, and density as it described in papers [1, 2]. Similarly to the transport code ASTRA [5], the magnetic surfaces are marked by the effective minor radius 0 / B π ρ Ψ = , which
THE INFLUENCE OF EMOTIONAL INTELLIGENCE ON SOFTWARE ENGINEERS ’ EMOTIONAL ADJUSTMENT AT WORKPLACE

The aim of present study has been to investigate Emotional Intelligence and its impact on Indian IT professionals’ emotional adjustment at workplace. The study was conducted in five major IT cities in India; NOIDA, DELHI, GURGAON, PUNE and BANGALURU. The study utilized a structured questionnaire developed by researcher based on emotional intelligence competencies as given by Daniel Goleman (1995, 1998). A sample of 414 software engineers from above mentioned major IT cities was used for statistical analysis. Data analysis included frequencies, percentages, mean scores, correlation and regression. The statistical data were computed by SPSS 16.0 for Windows. The analysis found statistically significant positive correlations between two variables of study; this means that increased emotional intelligence scores were associated with increased score of emotional adjustment at workplace amongst software engineers in Indian IT industry where the primary focus is on technical knowledge and expertise but soft skills.
KLF 2 Modulates CCR 5 Expression and Susceptibility to HIV-1 Infection 1

CCR5, a cell surface molecule critical for the transmission and spread of HIV-1, is dynamically regulated during T cell activation and differentiation. The molecular mechanism linking T cell activation to modulation of CCR5 expression remains undefined. KLF2 is a transcription factor that promotes quiescence, survival, and in part by modulating chemokine receptor levels, induces homing to secondary lymphoid organs. Given the relationship between T cell activation and chemokine receptor expression, we tested whether the abundance of KLF2 following T cell activation regulates CCR5 expression and thus susceptibility of a T cell to CCR5 dependent HIV-1 strains (R5). We observed a strong correlation between T cell activation, expression of KLF2 and CCR5, and susceptibility to infection. To directly measure how KLF2 affects CCR5 regulation, we introduced siRNA targeting KLF2 expression and demonstrated reduced KLF2 expression also resulted in less CCR5. Chromatin immunoprecipitation assays identified KLF2 bound to the CCR5 promoter in resting but not CD3/28 activated T cells, suggesting that KLF2 directly regulates CCR5 expression. Introduction of KLF2 under control of a heterologous promoter could restore CCR5 expression and R5 susceptibility to CD3/28 costimulated T cells and some transformed cell lines. Thus, KLF2 is a host factor that modulates CCR5 expression in CD4 T cells and influences susceptibility to R5 infection.
ANALYSIS OF THE ATTENUATOR-ARTIFACT IN THE EXPERIMENTAL ATTACK OF GUNN-ALLISON-ABBOTT AGAINST THE KLJN SYSTEM

After briefly summarizing our general theoretical arguments, we show that, the experienced strong information leak at the Gunn-Allison-Abbott attack [Scientific Reports 4 (2014) 6461] against the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange scheme, resulted from a serious design flaw of the system. The attenuator broke the single Kirchhoff-loop into two coupled loops. This is an illegal operation because the single loop is essential for the security, thus the observed leak is obvious. We demonstrate this by cracking the system with an elementary current comparison attack yielding close to 1 success probability for Eve even without averaging within a sub-correlation-time measurement window. A fully defended KLJN system would not be able to function, at all, due to its built-in current-comparison defense against active (invasive) attacks.
Identification of chemical elements in excavated human bones of ancient cemeteries from Greece

The research on chemical elements in human bones, which are identifying the health and nutrition of human beings is known. The difficulties for the searching-identification are many, because the bones are under decomposition or contamination from the environment where buried, and therefore we are not completely sure of the information we extract (Lambert et al., 1979). In our research we have identified a great number of chemical elements (14) from human bones as well as the nearby soil in different areas in Greece (Corfu island and Epirus). The chosen method was atomic absorption which is very sensitive and accurate for the elements we study. The specimens of the human skeletal material belong to long bones of the lower limbs, which were excavated in cemeteries, aged from the Archaic to the Classical Era. The research comprises a comparative study between two different areas of Greece, but also among the specimens relevantly with Age and Sex. The main conclusion is that Strontium and Zinc are the most important dietary discriminants.
Entry, Exit and Candidate Selection: Evidence from India

What motivates candidates to run in low income democracies? We examine the electoral impact of a voter awareness campaign which emphasized the responsibilities of local leaders in implementing a nation-wide public employment program. The intervention led to exit by the worse performing incumbents, substitution by incumbent family members and entry by challengers from traditionally disadvantaged groups. We contrast these effects with those of previous reservation for women, which weakens the incumbent who faces greater social pressure to not re-run. Previous reservation had similar effects on incumbency, accountability, and challenger entry, but did not change the composition of the candidate pool. This suggests that the wider political representation due to the campaign is not a mechanical effect from weakening the incumbent but reflects the motivation of candidates from disadvantaged groups to be in charge of the program. We find no evidence of a cumulative effect of the campaign with previous reservation.
C O ] 2 5 Ju l 2 01 9 On walks avoiding a quadrant

Two-dimensional (random) walks in cones are very natural both in combinatorics and probability theory: they are interesting in their own right and also in relation to other discrete structures. While walks restricted to the first quadrant have been well studied, the case of planar, non-convex cones—equivalent to the three-quarter plane after a linear transform—has been approached only recently. In this article we develop an analytic approach for the enumeration of walks in three quadrants. The advantage of this method is the uniform treatment of models corresponding to different step sets. After splitting the three quadrants into two symmetric convex cones, the method is composed of three main steps: write a system of functional equations satisfied by the counting generating function, which may be simplified into one single equation under symmetry conditions; transform the functional equation into a boundary value problem; and finally solve this problem, using a new concept of anti-Tutte’s invariant. The result is a contour-integral expression for the generating function. Such systems of functional equations also appear in queueing theory, namely, in the Join-the-Shortest-Queue model, which is still open in the non-symmetric case.

Understanding Zeros and Coherence in Japanese

This paper demonstrates the importance of identifying two types of zero arguments (zeros) to help teachers and learners of Japanese as a Second Language (JSL) understand the coherence of Japanese discourse. Zeros can be categorized into two types: “zero predicate-argument” and “zero nominal-argument. ” We will illustrate these two types of zeros and demonstrate why it is important to consider both types in order to have a better understanding of the cohesion among sentences, and hence of the coherence of discourse. The necessity to consider both zero types to improve our computer program, “Zero Detector,” an automatic zero detecting tool, will also be addressed.
R T ] 1 8 Ju l 2 01 8 n-abelian quotient categories

Let C be an (n+2)-angulated category with shift functor Σ and X be a cluster-tilting subcategory of C . Then we show that the quotient category C /X is an n-abelian category. If C has a Serre functor, then C /X is equivalent to an n-cluster tilting subcategory of an abelian category mod(ΣX ). Moreover, we also prove that mod(ΣX ) is Gorenstein of Gorenstein dimension at most n. As an application, we generalize recent results of Jacobsen-Jørgensen and Koenig-Zhu.
4 ATTITUDES AND THE IMPLICIT-EXPLICIT DUALISM

Since the mid-1990s, research on attitudes has been shaped by a dualism that has gained enormous . popularity across all areas of psychology: the implicit-explicit dualism (see Gawronski & Payne, ,~· . 2010). This dualism has its roots in the development of a new class of indirect measurement instru-; ments, which are distinguished from direct measurement instruments based on self-report. A central ~ '•. feature of these instruments is that they rely on e:l\. -perimental procedures adapted from cognitive ·~ ' psychology, such as sequential priming and response interference tasks (for an overview, see Gaw·_ ronski & De Houwer, 2014). Researchers often label these instruments implicit measures and self· report measures explicit measHres. A central characteristic of implicit measures as applied to the study of attitudes is that evalua. tive responses are inferred from objective performance indicators, such as participants' speed and -_: · accuracy in responding to attitudinal stimuli. Based on this characteristic, it has been argued that : · implicit measures are capable of assessing attitudes that people are either unwilling or unable to :: report. Resonating with these concerns, self-report measures have been criticized for their suscep,~ ~ tibility to socially desirable responding (Crowne & Marlowe, 1960; Paulhus, 1984) and for being unable to capture mental contents that are inaccessible to introspection (Greenwald & Banaji, ' 1995; Nisbett & Wilson, 1977). Implicit measures have been claimed to overcome these limitations, because (a) responses on implicit measures are much more difficult to control compared to explicit measures and (b) implicit measures do not require introspection for the assessment of :. ; mental contents. ; Although these assumptions are very common in the attitude literature, the available evidence • ·· suggests that differences between implicit and explicit measures cannot be boiled down to self. :~ · presentation and unawareness (Gawronski, LeBel, & Peters, 2007). Instead, the exponentially grow_ ing body of research in this area suggests that interpretations of different outcomes on the two . kinds of measures require more nuanced theoretical frameworks. The current chapter provides an overview of extant theories and research on the irnplici11-explicit dualism in the attitude literature. · Toward this end. we first provide a brief overview of the most popular instruments and then review ,. -~ different interpretations of the implicit-explicit dualism. E. '<:panding on this discussion, we review ·· ·. theories and empirical findings regarding (a) the relation between implicit and explicit measures, . (b) their predictive relation to behavior, (c) their usefulness in understanding the processes underly~ ing attitude formation and change, (d) context effects on implicit measures, and (e) controversies and current themes in research using implicit measures.
