ASSOCIATION FOR THE STUDY OF ASH * HIGHER EDUCATION

The relative influence of selected life history experiences on the development of three vocational types (investigative, social, and enterprising) proposed by J. L. Holland is studied using causal modeling procedures. The lack of explicitness in the developmental postulates of Holland's theory is seen as a major deficiency. Among the principal postulates of the theory is that most persons can be characterized by their resemblance to each of six personality types (realistic, investigative, artistic, social, enterprising, and conventional). A recent study using a biographical questionnaire d monstrates wide variations in the life histories of men and women in the six vocational types. Subjects for this study were obtained from respondents to the 1971 Cooperative Institutional Research Programs survey (completed on entering college in 1971) which obtained a broad array of personal information. Subjects also completed a follow-up survey in 1980 that gathered data on college experiences and educational and occupational achievements in the 9-year period. Findings support Holand's general premise that vocational type development is a function of a complex series of events resulting from family backgrounds, initial personal orientations and occupational preferences, and interactions with alternative environmental settings. The relative importance of life history experiences varies among the three types. Where one goes to college and what one does have important consequences for the development of Holland vocational types. Tables are included. Contains 29 references.

A real time biofeedback system using visual user interface for physical rehabilitation

This study was undertaken to investigate the effectiveness of biofeedback training when compared to conventional physical rehabilitation. Real time biofeedback plays an important role for patients and therapists to assessthe success and performance of the training process. Visual user interface allows new forms of therapy simplifying the process and increasing patients’ motivation. An experimental investigation was conducted to study the effect of using a visual interface as an add-on therapy to standard exercises for Range of Motion (ROM) measurements in glenohumeral movements. Human movement was collected by a Kinect sensor and the ROM measurements were computed using spatial coordinates provided by the official Microsoft Kinect SDK. The design allows patients to train therapeutic exercises, while receiving different types of real time feedback indicating measures of performance evaluation through the course of the training. Moreover, both the environment and the training task are customizable to the patient needs. In order to evaluate the biofeedback effectiveness, subjects that participated in the study were required to do a therapeutic exercise twice: firstly following the instructions of the therapist and secondly adding the visual biofeedback to the therapist instructions. The results obtained suggest that the proposed visual interface was an effective tool to achieve a significant improvement in the performance of the exercise. The exercises correctness when performed with visual feedback was significantly higher than the same exercises performed without this visual stimulus. In trials where subjects received visual feedback, it was observed a greater effort to achieve the proposed objective and superior movement control. Given the potential benefits of biofeedback, the proposed interface can become a helpful tool to patients that can confirm the correctness of their exercises and therapiststhat can adapt the prescribed exercises considering patients’ evolution and performance. © 2015 The Authors.

Evaluation of DNA extraction methods from dried and frozen tomato leaves for detecting begomoviruses by PCR.

SUMMARY Six DNA extraction protocols for dried and frozen tomato [Solanum lycopersicum (Mill)] leaves were evaluated to detect begomoviruses using polymerase chain reaction (PCR). The extraction method comparisons were based on DNA quantity and quality, extraction cost, and processing time. Four samples of dried and frozen tomato leaves, collected in the Venezuelan states of Zulia, Merida and Tachira, were evaluated. The DNA concentration and the ratios of 260 and 280µm absorbances were measured using spectrophotometry. Begomovirus detection was performed using degenerate primers for viral components A and B (DNA-A and DNA-B), and PCR band intensity was recorded using a visual scale. The SDS method produced greater DNA quantity and quality, and it is faster and less expensive than the other extraction protocols tested. Begomovirus DNAB was more consistent in amplification than DNA-A, sugges ting higher variability of the A component. Resuspended DNA pellets minimized the effects of inhibitors on the amplification because of the high sensitivity of the PCR technique, which also allowed begomovirus detection even when using small amounts of dried and frozen leaf tissue. The DNA isolated by the SDS method provides a simple and economical option for begomovirus screening in tomato using PCR, and could be used for large-scale epidemiological studies.
Communication skills in child protection: how do social workers talk to parents?

Communication skills are fundamental to social work practice, yet there is little research on the skills that workers have or how they use them. This study analyses 24 taped interviews between social workers and an actor playing a parent (a ‘simulated client’). Two child protection scenarios with different levels of seriousness were used. On average, social workers asked many closed questions and often raised concerns. They used few reflections and rarely identified positives. In all but one interview, social workers were rated as achieving clarity over issues of concern; however, they tended to demonstrate low levels of empathy. The responses of the simulated client were rated for resistance and information disclosure. The factor that most strongly influenced simulated client responses was empathy. Empathic social workers created less resistance and increased the amount of information disclosed by clients. This was not associated with failure to identify and discuss concerns. Empathy, therefore, appears to be central to good social work communication in child protection situations. Given the comparatively low level of empathy expressed by most participants, development of skills in maintaining empathic communication while raising child protection concerns appears a priority. Practical, theoretical and training implications are discussed.
Diffusion Paths : Fixed Points , Periodicity and Chaos

It is common to recognize that ideas, technology and information disseminate across the economy following some kind of diffusion pattern. Typically, the process of adopting a new piece of knowledge will be translated into an s-shaped trajectory for the adoption rate. This type of process of diffusion tends to be stable in the sense that convergence from any initial state towards the long-term scenario in which all the potential adopters enter in contact with the innovation is commonly guaranteed. Here, we introduce a mechanism under which stability of the diffusion process does not necessarily hold. When the perceived law of motion concerning the evolution of the number of potential adopters differs from the actual law of motion, and agents try to learn this law resorting to an adaptive learning rule, nonlinear long-term outcomes might emerge: the percentage of individuals accepting the innovation in the long-run may be a varying value that evolves according to some cyclical (periodic or a-periodic) pattern. The concept of nonlinear diffusion that is addressed is applied to a problem of information and monetary policy.

Evaluation of Bayesian Filters Applied to Heat Conduction Problems

In this paper we applied Bayesian filters to a state estimation problem involving a one-dimensional, transient, heat conduction problem. The main objective of this paper is to discuss and compare the performance of the several types of filters, namely: Sampling Importance Re-sampling Filter (SIR filter), Auxiliary Sampling Importance Re-sampling Filter (ASIR filter), Sequential Monte Carlo Samplers (SMC), Combined Parameter and State Estimation in Simulation Based Filtering, and Sequential Monte Carlo without Likelihoods. Results obtained with simulated experiments show a good performance of some of the filters, as applied to inverse heat conduction problems.
3 . 1 Defining Mobility Heuristics

Expert evaluation is a widely used method for evaluating the usability of software products. When evaluating games, traditional usability heuristics lack comprehension and cannot be directly applied. In this paper, we introduce playability heuristics that are specifically designed for evaluating mobile games. Heuristics form a core model that can be used in any mobile game evaluation. The model consists of three modules: Game Usability, Mobility, and Gameplay. The mobile context has some unique characteristics, which require special attention during the evaluation. These characteristics are described in mobility heuristics. Mobile devices also set some of their own requirements for general usability and these issues are described along with game usability heuristics. These heuristics have been developed by using an iterative design process of a mobile game. In addition, we have validated the heuristics and evaluated five mobile games by using them with the expert evaluation method. The results indicate that playability problems, which violate game usability or mobility heuristics, are quite easy to identify. Gameplay problems are harder to find, but gameplay heuristics help in evaluation and focus on different aspects of the gameplay.
CHARACTERIZATION AND ANALYSIS OF COOPERATIVE MERGERS AND THEIR RESULTS

This study characterizes the mergers and acquisitions undertaken in the Spanish agrifood sector during the period 1995-2005. First, it aims to establish the pre-merger financial characteristics of the merging cooperatives in comparison with other firms in the agrifood sector. For this, the financial situation is analyzed in the different types of merger carried out (merger by formation or merger by acquisition), and the different roles played by the cooperatives (acquiring, acquired or involved in a merger in which a new cooperative is formed). The second and final objective is to determine whether these mergers have managed to improve the economic-financial situation of the companies involved, either by increasing income and size or by reducing relative costs. For this purpose, several non parametric tests and a probit model were used. The results show that on average following a merger there were no statistically significant improvements in the economic-financial indicators studied.
Benevolent Sexism at Work

The current research draws from ambivalent sexism theory to examine potential gender differences in the quantity and quality of developmental work experiences. In a sample of managers in the energy industry, men and women reported participating in a similar number of developmental experiences (with comparable levels of support), but men rated these experiences as more challenging and received more negative feedback than did women. Similarly, a sample of female managers in the health care industry reported comparable amounts, but less challenging types, of developmental experiences than their male counterparts’. The results of three complementary experiments suggest that benevolent sexism is negatively related to men’s assignment of challenging experiences to female targets but that men and women were equally likely to express interest in challenging experiences. Taken together, these results suggest that stereotype-based beliefs that women should be protected may limit women’s exposure to challenging assignments, which in turn may partially explain the underrepresentation of women at the highest levels of organizations.
Ac ce pt ed M an us cr ip t Computational model for Vitamin D De ciency using Hair Mineral Analysis

Vitamin D de ciency is prevalent in the Arabian Gulf region, especially among women. Recent studies show that the vitamin D de ciency is associated with a mineral status of a patient. Therefore, it is important to assess the mineral status of the patient to reveal the hidden mineral imbalance associated with vitamin D de ciency. A well-known test such as the red blood cells is fairly expensive, invasive, and less informative. On the other hand, a hair mineral analysis can be considered an accurate, excellent, highly informative tool to measure mineral imbalance associated with vitamin D de ciency. In this study, 118 apparently healthy Kuwaiti women were assessed for their mineral levels and vitamin D status by a Hair Mineral Analysis (HMA). This information was used to build a computerized model that would predict vitamin D de ciency based on its association with the levels and ratios of minerals. The rst phase of the proposed model introduces a novel hybrid optimization algorithm, which can be considered as an improvement of Bat Algorithm (BA) to select the most discriminative features. The improvement includes using the mutation process of Genetic Algorithm (GA) to update the positions of bats with the aim of ∗Corresponding author Email addresses: aboitcairo@gmail.com (Aboul Ella Hassanien), engalaatharwat@hotmail.com (Alaa Tharwat ), halaown@gmail.com (Hala S.

2 The Programming Language : μ Java

For the object oriented (OO) world, developing formal semantics for theoretical study and practical use is still an important topic despite of a decade’s efforts. In this paper, for a sufficiently large subset of sequential Java with a pure reference semantics model, we define a Weakest Precondition (WP) semantics, and prove its soundness and completeness. Based on this WP semantics, we study specifications of methods and the refinement relationship between specifications, and we propose new definitions for object invariants and behavioral subtyping notation for general OO programs.

Marangoni flows induced by atmospheric-pressure plasma jets

We studied the interaction of atmospheric-pressure plasma jets of Ar or air with liquid films of an aliphatic hydrocarbon on moving solid substrates. The hydrodynamic jet-liquid interaction induces a track of lower film thickness. The chemical plasma-surface interaction oxidizes the liquid, leading to a local increase of the surface tension and a self-organized redistribution of the liquid film. We developed a numerical model that qualitatively reproduces the formation, instability and coarsening of the flow patterns observed in the experiments. Monitoring the liquid flow has potential as an in-situ, spatially and temporally resolved, diagnostic tool for the plasma-liquid surface interaction.
Genome Packaging Ribosomal Frameshift Signal in HIV-1 RNA Deciphering the Role of the Gag-Pol

A key step of retroviral replication is packaging of the viral RNA genome during virus assembly. Specific packaging is mediated by interactions between the viral protein Gag and elements in the viral RNA genome. In HIV-1, similar to most retroviruses, the packaging signal is located within the 5= untranslated region and extends into the gag-coding region. A recent study reported that a region including the Gag-Pol ribosomal frameshift signal plays an important role in HIV-1 RNA packaging; deletions or mutations that affect the RNA structure of this signal lead to drastic decreases (10to 50-fold) in viral RNA packaging and virus titer. We examined here the role of the ribosomal frameshift signal in HIV-1 RNA packaging by studying the RNA packaging and virus titer in the context of proviruses. Three mutants with altered ribosomal frameshift signal, either through direct deletion of the signal, mutation of the 6U slippery sequence, or alterations of the secondary structure were examined. We found that RNAs from all three mutants were packaged efficiently, and they generate titers similar to that of a virus containing the wild-type ribosomal frameshift signal. We conclude that although the ribosomal frameshift signal plays an important role in regulating the replication cycle, this RNA element is not directly involved in regulating RNA encapsidation.
Thrombectomy within 8 hours after symptom onset in ischemic stroke

Context Three trials showing no difference in clinical outcome between patients with acute ischaemic stroke (AIS) treated by mechanical thrombectomy (MT) and those treated by intravenous thrombolysis (IVT) had the effect of reducing the number of patients with AIS receiving endovascular therapy. Based on the enthusiasm of recent positive findings from the MR CLEAN, ESCAPE and EXTEND-IA trials, the REVASCAT and SWIFT PRIME trials have been stopped prematurely due to their positive findings and their results were released in April 2015. In both studies, MT was performed with the Solitaire revascularisation device, a selfexpanding stent used to retrieve thrombi and restore blood flow, showing faster and higher rate of reperfusion, lower intracranial haemorrhage and better outcomes.
Generalized Ideal Point Models for Time-Varying and Missing-Data Inference

This paper presents an item-response theory parameterization of ideal points that unifies existing approaches to ideal point models while also extending them. For time-varying inference, the model permits ideal points to vary in a random walk, in a stationary autoregressive process, or in a semi-parametric Gaussian process. For missing data, the model implements a two-stage selection adjustment to account for non-ignorable missingness. In addition, the ideal point model is extended to handle new distributions, including continuous, positive-continuous and ordinal data. To enable modeling of datasets with mixed data (discrete and continuous), I incorporate joint modeling of different distributions. Finally, I also address ways of implementing Bayesian inference with big data sets, including variational inference and within-chain MCMC parallelization.
Are Groups Better Planners than Individuals? An Experimental Analysis

We present the results of an experiment comparing group and individual planning in the domain of lifecycle consumption/saving decisions. Individual decision making is compared to two group treatments, which differ based on the presence of a rematching rule. We find that individuals and groups differ in how they solve the intertemporal consumption problem, but not in how they improve their consumption planning within a sequence. Individuals’ performance improves across sequences, groups without rematching perform approximately the same, while groups with rematching do significantly worse. Our main finding is that while groups perform better than individuals in the first sequence, this difference seems to disappear in the second lifecycle. Results show that in the second sequence groups in the rematching treatment deviate substantially more from optimum than groups that are left stable across sequences.
Advances on materials and methods for sensing salmonella infections

Salmonella infectious diseases spreading every day through food have become a lifethreatening problem for millions of people and growing menace to society. Health expert’s estimate that the yearly cost of all the food borne diseases is approximately $5–6 billion. Traditional methodologies for salmonella analysis provide high reliability and very low limits of detection. Among them immunoassays and Nucleic acid-based assays provide results within 24 h, but they are expensive, tedious and time consuming. So, there is an urgent need for development of rapid, robust and cost-effective alternative technologies for real-time monitoring of salmonella. Several biosensors have been designed and commercialized for detection of this pathogen in food and water. In this overview, we have updated the literature concerning novel biosensing methods such as various optical and electrochemical biosensors and newly developed nanoand micro-scaled and aptamers based biosensors for detection of salmonella pathogen. Furthermore, attention has been focused on the principal concepts, applications, and examples that have been achieved up to diagnose salmonella. In addition, commercial biosensors and foreseeable future trends for onsite detecting salmonella have been summarized.
Pressure and Heat Transfer in Staggered Arrangement Circular Tubes with Airfoil Vortex Generator

In this paper the numerical solution of flow and heat transfer have been computed on staggered arrangement circular tubes and modeled by Navier-Stokes and energy equations. Two-dimensional flow, with Reynolds numbers between 100 to 500 is used. Flow is assumed to be incompressible, steady state and the thermo physical characteristics are constant. The elliptic differential equations are used to generate orthogonal grid and finite volume equations are solved to link pressure and velocity terms. Nusselt numbers, pressure changes, velocity and friction coefficients have been obtained in two conditions of with and without obstacle, and compared. The results show that the usage of airfoil obstacle is efficient for increasing heat transfer in spite of more friction coefficient and more pressure reduction.
