Structural Equation Modelling in Behavioral Intention to Use Safety Helmet Reminder System

Motorcycle is one of private transportation which has been widely used in many countries including Malaysia. However, motorcycles are the most dangerous form of motorized transport. Royal Malaysian Police (PDRM) statistics recorded that motorcycle is the highest vehicle (45.9%) involved in traffic accident compared to other vehicles. The potential cause of the death to the motorcyclist was due to the head injury. One of strategy to mitigate this problem is through proper usage of safety helmet. Therefore, this paper was introduce a new approach on motorcyclist safety by using the Technology Acceptance Model (TAM) with additional determinants that contribute to behavioral intention and to increase the proper usage of safety helmets among Malaysian motorcyclists. The Structural Equation Modelling (SEM) was used to test the structural TAM proposed. The evaluation for structural model showed the goodness of fit indices are excellent fit. This study found that perceived ease of use, perceived usefulness and social norm are significant towards behavioral intention to use Safety Helmet Reminder System (SHR). © Owned by the authors, published by EDP Sciences, 2016 Language: en
Partial discharge detection and localization inside the winding of power transformer

In this paper, an electrical method is used to detect and locate partial discharge (PD) inside the winding of a three phases, 45 kVA transformer. PD is created in a separate cell outside the transformer winding using a needle-plane electrode arrangement and injected to each of the four taps in each phase of the transformer winding. The PD signal was measured as a voltage drop across a resistance connected to the ground. Different forms of PD are generated inside the transformer, i.e. sharp edge, bubble and surface discharge. Seventy PD signals are measured at each location for each PD source. Statistical features (variance, skewness and kurtosis) extracted from the measured signals have been used as an input feature to a feed-forward back-propagation artificial neural network. High recognition rate for both PD source and location has been achieved.
An MTL-Based Configurable Block for Current-Mode Nonlinear Analog Computation

A configurable analog block (CAB) architecture based upon the MOS translinear (MTL) principle is proposed. It is programmed to implement some current-mode nonlinear analog computational functions. The proposed CAB architecture consists of one cascoded MTL cell, a local switch network, and a pMOS array. The cascoded MTL cell implements one MTL loop that is reconfigurable and programmable using the switch network and the pMOS array. This CAB architecture is capable of implementing various frequently used nonlinear functions, such as squaring/inverse function, rectifying (absolute value), and square-rooting/geometric mean functions. The CAB has been fabricated in a 0.5- μm CMOS technology and verifies the concept. High capability and flexibility of the proposed CAB makes it suitable for current-mode analog computational and signal processing applications.
high-resolution Mapping of Postinfarction reentrant Ventricular tachycardia electrophysiological characterization of the circuit

BACKGROUND: In vivo description of ventricular tachycardia (VT) circuits is limited by insufficient spatiotemporal resolution. We used a novel high-resolution mapping technology to characterize the electrophysiological properties of the postinfarction reentrant VT circuit. METHODS: In 15 swine, myocardial infarction was induced by left anterior descending artery balloon occlusion. Animals were studied 6 to 8 weeks after myocardial infarction. Activation mapping of VTs was performed by using the Rhythmia mapping system. Activation time was based on a combination of bipolar and unipolar electrograms. The response to overdrive pacing from different zones of the circuit was examined. RESULTS: A total of 56 monomorphic VTs were induced (3.8±2.1 per animal). Among these, 21 (37.5%) were hemodynamically stable and allowed mapping of the circuit. Isthmuses were 16.4±7.2 mm long and 7.4±2.8 mm wide. Conduction velocities were slowest at the inward curvature into the isthmus entrance (0.28±0.2 m/s), slightly faster at the outward curvature exit (0.40±0.3 m/s) and nearly normal at the central isthmus (0.62±0.2 m/s). In 3 animals, 2 VT morphologies with opposite axes sharing the same isthmus were mapped. Conduction velocities within the shared isthmus were dependent on the activation vector, consistently slower at the proximal curvature. Overdrive pacing from isthmus sites determined by activation mapping was consistent with entrainment criteria for isthmus. However, dimensions of the isthmus defined by entrainment exceeded dimensions of the isthmus measured by activation mapping by 32±18%. CONCLUSIONS: In postinfarction reentrant VT, conduction velocities are slowest at the proximal and distal curvatures. Entrainment mapping overestimates the true size of the isthmus. High-resolution activation mapping of attempted to map all hemodynamically tolerated monomorphic VTs. These were defined as VTs with a systolic blood pressure ≥ 80 mm Hg. If the VT was not hemodynamically tolerated, it was terminated by pacing or electric cardioversion. In these cases, inotropic support (phenylephrine bolus of 5–10 mg) was administered to increase the blood pressure before the next attempt to induce VT. Furthermore, if the tachycardia cycle length (TCL) was ≤ 220 ms, procainamide (5 mg/kg bolus followed by infusion at a rate of 2–4 mg/min) was administered in an attempt to increase the TCL.
Employee Post‐Training Behaviour and Performance: Evaluating the Results of the Training Process

Despite the fact that firms invest in training, there is considerable evidence to show that training programmes often fail to achieve the intended result of improving worker and organization performance. The purpose of this paper is to examine the medium‐ to long‐term effects of training programmes on firms by means of an integrated research model combining the principal factors that the existing literature has shown to be related to training transfer and also by examining the relationship between training transfer and operational performance. The transfer factors chosen are training design, trainee self‐efficacy and work environment. The validity of this model is tested by applying the structural equation modelling approach to data from 126 employees who have participated in various training programmes in a number of Greek organizations. The results indicate that the design of a training programme has the strongest impact on post‐training job performance, along with trainees' self‐efficacy and post‐training behaviour.
Genome Sequence of a Nicotine-Degrading Strain of Arthrobacter

ABSTRACT We announce a 4.63-Mb genome assembly of an isolated bacterium that is the first sequenced nicotine-degrading Arthrobacter strain. Nicotine catabolism genes of the nicotine-degrading plasmid pAO1 were predicted, but plasmid function genes were not found. These results will help to better illustrate the molecular mechanism of nicotine degradation by Arthrobacter.
Worqbench: An Integrated Framework for e-Science Application Development

With the proliferation of Grid computing, potentially vast computational resources are available for solving complex problems in science and engineering. However, writing, deploying, and testing e-Science applications over highly heterogeneous and distributed infrastructure are complex and error prone. Further complicating matters, programmers may need to target a variety of different Grid middleware packages. This paper presents the design and implementation of Worqbench, an integrated, modular and middleware neutral framework for e- Science application development on the Grid. Worqbench can be incorporated into a number of existing Integrated Development Environments, further leveraging the advantages of such systems. We illustrate one such implementation in the Eclipse environment.
Research Reports*

This study was designed to investigate patient response to orthognathic surgery with specific reference to personality trait analyses and their changes with surgery and to see if any particular personality traits could be used as predictors for post-operative problems. Patients', parents', and peers' ·responses to treatment were also studied. Twenty consecutive patients attending for orthognathic surgery and two control groups underwent personality assessment using the Cattell l6.P.F. Questionnaire at predetermined time intervals. Satisfaction questionnaires were administered to the patient, a parent, and friend, at 10 weeks postoperatively. The results indicate that the majority of patients appeared to experience positive personality changes with treatment. Some patients demonstrated high anxiety levels and emotional instability pre-operatively and most of this group experienced postoperative problems whilst the psychologically normal group did not. There was overall high satisfaction with treatment and its outcomes, but some treatment problems were identified. It was concluded that pre-operative psychological assessment could be a valuable aid to patient management and that thorough patient evaluation and preparation for surgery and effective communication are necessary to ensure complete treatment success.
The social impact of computers

During two recent years at MIT, I had a teletypewriter assigned to my use. The teletype gave me instant access to a large computer complex in which I had various sets of data stored. The teletype was located in a basement room which was generally dark except for the light focused over my teletype and small desk. It was always silent in that room except for the noise of the teletype. In this setting, I would conduct analysis of my data by the hour. I would sort along particular variables, intersect those which seemed promising and in this way be led from one avenue of investigation to another. I was in effect carrying on a dialogue with the computer. I asked a question and I got an answer. The answer led me to other questions. Sometimes the computer would complain that I had not made my inquiry in the correct form and it would suggest that I try again. It kept me informed of the time I had used and how much I had remaining; what data sets I had placed on file and what analysis I had completed. I could cuss it (and often did), thank it, wait impatiently the few seconds it sometimes required to respond, and get excited about what it was telling me. Given all of this, it should not seem strange that this machine came to be human to me for long periods of time. It had personality, value, integrity---and it carried on conversations with me alone. I understand Kronenberg when he says "computers are good guys. "
Enhancing the Security of Parallel Programs via Reducing Scheduling Space

Parallel programs face a new security problem - concurrency vulnerability, which is caused by a special thread scheduling instead of inputs. In this paper, we propose to automatically fix concurrency vulnerabilities by reducing thread scheduling space. Our method is based on two observations. First, most concurrency vulnerabilities are caused by atomicity violation errors. Second, reducing thread scheduling space does not harm the correctness of the original program. We designed a prototype runtime system shield using deterministic multithreading techniques. Shield is designed to transparently run parallel programs and schedule threads in large instruction blocks to prevent atomicity violation at best effort. In case some concurrency vulnerabilities cannot be fixed by shield's scheduling reducing scheme, we also provide a remedy strategy by integrating shield with record&replay function, so that it can help programmers to analyze attacker's behavior for manually fixing.
Methods for characterizing convective cryoprobe heat transfer in ultrasound gel phantoms.

While cryosurgery has proven capable in treating of a variety of conditions, it has met with some resistance among physicians, in part due to shortcomings in the ability to predict treatment outcomes. Here we attempt to address several key issues related to predictive modeling by demonstrating methods for accurately characterizing heat transfer from cryoprobes, report temperature dependent thermal properties for ultrasound gel (a convenient tissue phantom) down to cryogenic temperatures, and demonstrate the ability of convective exchange heat transfer boundary conditions to accurately describe freezing in the case of single and multiple interacting cryoprobe(s). Temperature dependent changes in the specific heat and thermal conductivity for ultrasound gel are reported down to -150 °C for the first time here and these data were used to accurately describe freezing in ultrasound gel in subsequent modeling. Freezing around a single and two interacting cryoprobe(s) was characterized in the ultrasound gel phantom by mapping the temperature in and around the "iceball" with carefully placed thermocouple arrays. These experimental data were fit with finite-element modeling in COMSOL Multiphysics, which was used to investigate the sensitivity and effectiveness of convective boundary conditions in describing heat transfer from the cryoprobes. Heat transfer at the probe tip was described in terms of a convective coefficient and the cryogen temperature. While model accuracy depended strongly on spatial (i.e., along the exchange surface) variation in the convective coefficient, it was much less sensitive to spatial and transient variations in the cryogen temperature parameter. The optimized fit, convective exchange conditions for the single-probe case also provided close agreement with the experimental data for the case of two interacting cryoprobes, suggesting that this basic characterization and modeling approach can be extended to accurately describe more complicated, multiprobe freezing geometries. Accurately characterizing cryoprobe behavior in phantoms requires detailed knowledge of the freezing medium's properties throughout the range of expected temperatures and an appropriate description of the heat transfer across the probe's exchange surfaces. Here we demonstrate that convective exchange boundary conditions provide an accurate and versatile description of heat transfer from cryoprobes, offering potential advantages over the traditional constant surface heat flux and constant surface temperature descriptions. In addition, although this study was conducted on Joule-Thomson type cryoprobes, the general methodologies should extend to any probe that is based on convective exchange with a cryogenic fluid.
The EMO-Model: An Agent-Based Model of Primate Social Behavior Regulated by Two Emotional Dimensions, Anxiety-FEAR and Satisfaction-LIKE

Agent-based models provide a promising tool to investigate the relationship between individuals’ behavior and emerging group-level patterns. An individual’s behavior may be regulated by its emotional state and its interaction history with specific individuals. Emotional bookkeeping is a candidate mechanism to keep track of received benefits from specific individuals without requiring high cognitive abilities. However, how this mechanism may work is difficult to study in real animals, due to the complexity of primate social life. To explore this theoretically, we introduce an agent-based model, dubbed EMO-model, in which we implemented emotional bookkeeping. In this model the social behaviors of primate-like individuals are regulated by emotional processes along two dimensions. An individual’s emotional state is described by an aversive and a pleasant dimension (anxiety and satisfaction) and by its activating quality (arousal). Social behaviors affect the individuals’ emotional state. To implement emotional bookkeeping, the receiver of grooming assigns an accumulated affiliative attitude (LIKE) to the groomer. Fixed partner-specific agonistic attitudes (FEAR) reflect the stable dominance relations between group members. While the emotional state affects an individual’s general probability of executing certain behaviors, LIKE and FEAR affect the individual’s partner-specific behavioral probabilities. In this way, emotional processes regulate both spontaneous behaviors and appropriate responses to received behaviors, while emotional bookkeeping via LIKE attitudes regulates the development and maintenance of affiliative relations. Using an array of empirical data, the model processes were substantiated and the emerging model patterns were partially validated. The EMO-model offers a framework to investigate the emotional bookkeeping hypothesis theoretically and pinpoints gaps that need to be investigated empirically.
Standing Behind and Listening to Native Hawaiian Students in the Transition Process

The purpose of this qualitative multiple case study was to describe how culture, disability, and prospective first-generation college student status influenced the transition decisions of five native Hawaiian students with specific learning disabilities who attended a Hawaiian-focused charter school. Students had strong ties to their history and culture which influenced all facets of their lives including their decisions about the future. Accessing postsecondary education (PSE) was viewed as a means to employment that would enable them to support their family members. The lack of economic, social, and cultural capital may present a larger barrier to accessing PSE than disability. Implications for personnel who are tasked with developing and maintaining culturally appropriate curricula and programs for students are discussed.
Inhibitors of V-ATPases: old and new players

SUMMARY V-ATPases constitute a ubiquitous family of heteromultimeric, proton translocating proteins. According to their localization in a multitude of eukaryotic endomembranes and plasma membranes, they energize many different transport processes. Currently, a handful of specific inhibitors of the V-ATPase are known, which represent valuable tools for the characterization of transport processes on the level of tissues, single cells or even purified proteins. The understanding of how these inhibitors function may provide a basis to develop new drugs for the benefit of patients suffering from diseases such as osteoporosis or cancer. For this purpose, it appears absolutely essential to determine the exact inhibitor binding site in a target protein on the one side and to uncover the crucial structural elements of an inhibitor on the other side. However, even for some of the most popular and long known V-ATPase inhibitors, such as bafilomycin or concanamycin, the authentic structures of their binding sites are elusive. The aim of this review is to summarize the recent advances for the old players in the inhibition game, the plecomacrolides bafilomycin and concanamycin, and to introduce some of the new players, the macrolacton archazolid, the benzolactone enamides salicylihalamide, lobatamide, apicularen, oximidine and cruentaren, and the indolyls.
Commentary: Forms of Relationship Construction and the Power of the Child

The work by Goh and Kuczynski (2009) is important beyond the specific context of China. Using social relational theory, the authors examine family dynamics in the contemporary nursing practices of five families in Xiamen, China. While they succeed in identifying relations and patterns of interaction, they do not explain the mechanism that enables the emergence of these patterns. In this article, I suggest a complementary way, which does not exclude theirs, to show how developments and concepts derived from general systems theory and from the general perspective of dynamic systems could contribute to understanding the relations that are built in these families.
Medicalisation or under-treatment? Psychotropic medication use by elderly people in New Zealand

Abstract The increased use of information technology in health care allows researchers to generate data on rates of medication use among population groups, raising questions as to whether these rates are too high or too low. This paper presents findings from a study of records of all prescription medication dispensed in one New Zealand region (Te Tāirawhiti) over a one year period. The study examined patterns of psychotropic medication use amongst older people, by age, gender, ethnicity and socio-economic position. It concludes that the chances of being defined as needing psychotropic medication, that is, of being ‘medicalised’, are not evenly spread through the elderly population. Gender, age and ethnicity impacted significantly on whether prescriptions were received. Our results suggest the need for a nuanced understanding of the medicalisation of unhappiness and deviant behaviour amongst the elderly which takes into account barriers to treatment for some social groups.
