WOMEN LEADERSHIP COMPETENCY FROM THE PERSPECTIVE AMONG LECTURER AT UNIVERSITY XYZ

In an increasingly competitive and changing environment, women leaders in education face a variety of challenges. Although women dominate the labor force in large number, however in higher education sector, most of senior lecturers are men. The purpose of this study is to examine the leadership competency of women lecturer in the perspective of a lecturer at University XYZ and the effect of gender in ranking of competency skill. This study also intended to know the role of ranking in advancing women to a senior lecturer positions. This quantitative study used simple random sampling technique with 361 lecturers of University XYZ as the sample of the study. Questionnaire was distributed through online. The data was then analyzed by using Statistical Package for Social Science v22 (SPSS version 22). The results shows that self-management are the most important leadership competencies needed by women lecturers, follow by communication, business acumen, and leadership ability. Leadership competency is needed for the career development especially for women leaders in education. The model of leadership competency is a guideline for a women leader to evaluate their leadership competency in education sector

Drug and alcohol abuse at the work-place

Malaysia is the country that have strong legal control to the drug and alcohol among the Asia countries. Malaysia has prepared the guidelines that intended to provide guidance to employers and employees to prevent and respond to the issues from drug and alcohol use which to satisfy their obligations under the OSHA 1994. This action is to develop the prevention responses to the drug and alcohol issues in the workplace within Malaysia. There are many of issues that occurred in the workplace because the various forms of drug and alcohol that use by employees that effect their job performance when they are on duty especially operating machines such as alcohol, illicit drugs (heroin), non-predicate medicines (cough medicine) and others. Besides that, drug and alcohol abuse at the workplace may cause the risk injury of employees. Therefore, drug and alcohol use are totally prohibited in Malaysia and totally should be prevented in the workplace that can result in issues at work

Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples

Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

Study On RF Signal Propagation In An Indoor Environment For Wireless Communication Applications

This dissertation presents an improved variant of ray tracing technique, which we term as ray-polygon tracing, for propagation modelling. Generic polygons are used to represent the infinite number of rays(high frequency signals) emitted. The ray-polygons are clipped by obstacles, as they propagate away from the transmitter. In the mean time, new reflected and transmitted ray-polygons and images are created

Normalized frequency for noncircular dielectric waveguides

This paper points out that the commonly used normalized frequency for noncircular dielectric waveguides, which is based on the semiminor axis, causes the cross-sectional area to vary with the cross-sectional shape. Consequently, the shape effects described with the conventional normalized frequency are not due to the shape alone but the combined effects of the shape and area. Our numerical results show that the area effect is greater than the shape effect. An improved definition of normalized frequency based on an equivalent radius is proposed in this paper. Conversion formulas to convert from the conventional normalized frequency to the proposed normalized frequency are provided for elliptical and rectangular waveguides. Our numerical results show that the shape effects described by the proposed normalized frequency are free from the area effect. Consequently, the proposed normalized frequency is more accurate than the conventional normalized frequency in describing the shape effect of noncircular dielectric waveguides

An Accurate and Efficient 3-D Shooting-and-Bouncing-Polygon Ray Tracer for Radio Propagation Modeling

This paper describes two important improvements to a 3-D shooting-and-bouncing-polygon (SBP) ray tracer for radio propagation modeling. It introduces a way to trace diffracted-reflected (D-R) rays in the SBP framework and improves SBP accuracy when the D-R rays play an important role. It also introduces a better space partitioning scheme for the use with SBP and improves the SBP's computation efficiency by more than 10× in some applications. The numerical results are compared against published measurements and 3-D full-wave solutions. They show that the improved SBP ray tracer is a good multipurpose 3-D ray tracer which can be used to simulate urban street canyon (without double over-rooftop diffraction), indoor, and tunnel propagation environments

Multilayer Wall Correction Factors for Indoor Ray-Tracing Radio Propagation Modeling

A single-layer or multilayer wall with thickness can be modeled accurately and efficiently as one infinitesimally thin patch in ray tracing by using correction factors to compensate for the ray path errors. This communication presents the correction factors to be used with the classical multiple-dielectric-interface reflection and transmission coefficients, for reflected, transmitted, and diffracted ray paths. It is shown that, with the aid of the correction factors, the ray-tracing simulation of an indoor scene with a penetrable hollow wedge formed by multilayer walls can produce results that match the 3-D full-wave results

Imbalance in <i>Unc80</i> RNA Editing Disrupts Dynamic Neuronal Activity and Olfactory Perception

A-to-I RNA editing, catalyzed by the ADAR protein family, significantly contributes to the diversity and adaptability of mammalian RNA signatures, aligning with developmental and physiological needs. Yet, the functions of many editing sites are still to be defined. The Unc80 gene stands out in this context due to its brain-specific expression and the evolutionary conservation of its codon-altering editing event. The precise biological functions of Unc80 and its editing, however, are still largely undefined. In this study, we first demonstrated that Unc80 editing occurs in an ADAR2-dependent manner and is exclusive to the brain. By employing the CRISPR/Cas9 system to generate Unc80 knock-in mouse models that replicate the natural editing variations, our findings revealed that mice with the “gain-of-editing” variant (Unc80G/G) exhibit heightened basal neuronal activity in critical olfactory regions, compared to the “loss-of-editing” (Unc80S/S) counterparts. Moreover, an increase in glutamate levels was observed in the olfactory bulbs of Unc80G/G mice, indicating altered neurotransmitter dynamics. Behavioral analysis of odor detection revealed distinctive responses to novel odors—both Unc80 deficient (Unc80+/−) and Unc80S/S mice demonstrated prolonged exploration times and heightened dishabituation responses. Further elucidating the olfactory connection of Unc80 editing, transcriptomic analysis of the olfactory bulb identified significant alterations in gene expression that corroborate the behavioral and physiological findings. Collectively, our research advances the understanding of Unc80’s neurophysiological functions and the impact of its editing on the olfactory sensory system, shedding light on the intricate molecular underpinnings of olfactory perception and neuronal activity
