The Influence of Leadership on Employee Performance Among Jewellery Artisans in Malaysia

The purpose of this paper is to examine the leadership influence on employee job performance, in this case, in the jewellery industry in Malaysia. Various studies tried to examine leadership style and its influence on employee performance, job performance, firm’s performance and commitment. The results was mixed, some are positive and some are negative. In the past, most of the research have taken various leadership styles that are cited under different leadership theories. This study has selected leadership styles such as supportive, participative, servant, transactional and transformational leadership styles as independent variables that are assumed to have direct influence on employee job performance, which is the dependent variable. A survey self-rating scale questionnaire was developed using past literature to examine leadership styles and employee performance. A sample of 115 respondents were recruited using simple random probability sampling technique. The collected data was recorded and analysed using SPSS 22.0. The finding shows that only supportive and transformational leadership behaviour positively and significantly influences employee performance at workplace. We found the other three leadership behvaiour such as servant, participative and transactional leadership behaviours are not significant in influencing employee performance. Therefore we concluded that only transformational and supportive leadership behaviour directly influences employee performance. Managers must find ways to cultivate supportive and transformational leadership behvaiour to improve employee job performance, especially among the Jewellery industry managers.
The Area Theorem

We prove that the area of sections of future event horizons in space– times satisfying the null energy condition is non–decreasing towards the future under any one of the following circumstances: 1) the horizon is future geodesically complete; 2) the horizon is a black hole event horizon in a globally hyperbolic space–time and there exists a conformal completion with a “H–regular” I +; 3) the horizon is a black hole event horizon in a space–time which has a globally hyperbolic conformal completion. (Some related results under less restrictive hypotheses are also established.) This Supported in part by KBN grant # 2 P03B 130 16.

Behavioral intention model for the exchange mode Internet music piracy

In recent years, with the rapid growth of the Internet, the situation of Internet music piracy has become increasingly serious. In particular, the exchange mode of music downloading as a form of peer-to-peer electronic commerce is gaining fast acceptance in the user community. However, the exchange mode of music downloading is also particularly prone to being misused for music piracy. It is therefore important to understand the factors affecting users' behavioral intention to use the exchange mode Internet music piracy (EMIMP). The identification of such factors and their relative importance can help formulation of more effective strategy for deterring music piracy through the exchange mode of downloading. This paper empirically tests the research model by explaining the behavioral intention of EMIMP, identifying the relevant antecedent factors and the processes involved. The role of deterrence and perceived equitable relationship in EMIMP has been established both theoretically and empirically.
FlexSched : a Flexible Data Schedule Generator for Multi-Channel Broadcast Systems

This paper is concerned with the issue of building efficient and flexible data broadcast programs for a multiple physical channel environment. The goal of our work has been twofold: (a) to minimize the cost of building the broadcast program and (b) to minimize the average access latency for data requests of mobile clients. To achieve both goals, a highly flexible scheduler, called FlexSched, is proposed, taking a divide-and-conquer approach to solve the data scheduling problem. To determine the optimal allocation of the data to the existing physical channels, FlexSched initially makes a single scan over the vector of access probabilities of the data items and assigns them to the broadcast channels based on the square-root formula of optimal bandwidth usage, i.e., data items are mapped to channels in proportion to the square-root of their access probabilities. For each physical channel a skewed broadcast schedule is then produced by first assigning each data item to its own data group and then iteratively merging neighboring data groups so that the overall average access time of the initial schedule is continously reduced. The merging procedure terminates if there are no more neighboring data groups in the program whose merging would further decrease the overall average access latency. An extensive performance study confirms the effectiveness and efficiency of FlexSched. It is shown that FlexSched significantly outperforms existing data scheduling schemes, while being able to generate the broadcast schedule with an average time complexity of O(N logN).
Tolerance by Surprise: Evidence for a Generalized Reduction in Prejudice and Increased Egalitarianism through Novel Category Combination

Prejudices towards different groups are interrelated, but research has yet to find a way to promote tolerance towards multiple outgroups. We devise, develop and implement a new cognitive intervention for achieving generalized tolerance based on scientific studies of social categorization. In five laboratory experiments and one field study the intervention led to a reduction of prejudice towards multiple outgroups (elderly, disabled, asylum seekers, HIV patients, gay men), and fostered generalized tolerance and egalitarian beliefs. Importantly, these effects persisted outside the laboratory in a context marked by a history of violent ethnic conflict, increasing trust and reconciliatory tendencies towards multiple ethnic groups in the Former Yugoslav Republic of Macedonia. We discuss the implications of these findings for intervention strategies focused on reducing conflict and promoting peaceful intergroup relations.
Gesture Recognition Technology: A Review

Gesture Recognition Technology has evolved greatly over the years. The past has seen the contemporary Human – Computer Interface techniques and their drawbacks, which limit the speed and naturalness of the human brain and body. As a result gesture recognition technology has developed since the early 1900s with a view to achieving ease and lessening the dependence on devices like keyboards, mice and touchscreens. Attempts have been made to combine natural gestures to operate with the technology around us to enable us to make optimum use of our body gestures making our work faster and more human friendly. The present has seen huge development in this field ranging from devices like virtual keyboards, video game controllers to advanced security systems which work on face, hand and body recognition techniques. The goal is to make full use of the movements of the body and every angle made by the parts of the body in order to supplement technology to become human friendly and understand natural human behavior and gestures. The future of this technology is very bright with prototypes of amazing devices in research and development to make the world equipped with digital information at hand whenever and wherever required.
Role of Sterol Regulatory Element Binding Proteins in the Regulation of G&agr;i2 Expression in Cultured Atrial Cells

We have previously demonstrated that growth of embryonic chick atrial cells in medium supplemented with lipoprotein-depleted serum (LPDS) resulted in a coordinate increase in the expression of genes involved in the parasympathetic response of the heart (the M2 muscarinic receptor; the &agr;-subunit of the heterotrimeric G protein, G&agr;i2; and the inward rectifying K+ channel protein, GIRK1) and a marked increase in the negative chronotropic response of atrial cells to muscarinic stimulation. In the present study, we demonstrate that regulation of G&agr;i2 promoter activity by LPDS is mediated by the binding of a sterol regulatory element binding protein (SREBP) to a sterol regulatory element (SRE) in the G&agr;i2 promoter. Deletion and point mutation of this putative SRE interfered with the regulation of the G&agr;i2 promoter by SREBP and LPDS. Furthermore gel shift assays demonstrated that point mutations in the putative G&agr;i2 SRE markedly inhibited the binding of purified SREBP to oligonucleotides containing the G&agr;i2 SRE sequence. The expression of a dominant-negative SREBP mutant interfered with LPDS stimulation of G&agr;i2 promoter activity. Finally, we demonstrate that SREBP-1 is markedly more potent than SREBP-2 for the stimulation of G&agr;i2 promoter activity, suggesting that SREBP1 may play a role in the regulation of G&agr; i2 expression. These are the first data to demonstrate SREBP regulation of a protein not involved in lipid homeostasis and suggest a new relationship between lipid metabolism and the parasympathetic response of the heart.

The Students' Perceptions of Creating Videos to Engage Them in Speaking

This research investigates the students’ perceptions of creating videos to engage them in speaking. This research employed a descriptive method. The population of this research was the third year students of Social Program of SMAN 1 Soppeng in the academic year 2017/2018. This research used purposive sampling, taking XII IPS 1 totaling 25 students as the sample. The instruments of this research were questionnaire and interview. The results of this research showed that creating videos has many advantages in engaging the students to speak English. Recording the conversation or dialogue is a fun activity for them although they feel nervous for the first few minutes, a few minutes later, they feel very much enjoying recording their activities and performance with their friends. Creating videos seems to be interesting and motivating the students to speak fluently. The students stated that they can see their expressions, gestures, and their mistakes by replaying their videos, so it will make them aware of their weakness and their mistakes. It creates self-learning and self-evaluation for the students. It makes the students motivated to improve their speaking skills. Thus, it is concluded that the students have positive perceptions on the effectiveness of creating videos in engaging them to speak English.
Hubble Space Telescope Images of Submillimeter Sources: Large Irregular Galaxies at High Redshift

We present new Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) high-resolution optical imaging of a sample of 13 submillimeter luminous galaxies for which the optical emission has been pinpointed either through radio 1.4 GHz or millimeter interferometry. We find a predominance of irregular and complex morphologies in the sample, suggesting that mergers are likely common for submillimeter galaxies. The component separations in these objects are on average a factor 2 larger than in local galaxies with similarly high bolometric luminosities. The sizes and star formation rates of the submillimeter galaxies are consistent with the maximal star formation rate densities of 20 M☉ kpc-2 in local starburst galaxies (Lehnert & Heckman). We derive quantitative morphological information for optical galaxies hosting submillimeter emission: total and isophotal magnitudes, Petrosian radius, effective radius, concentration, aspect ratio, surface brightness, and asymmetry. We compare these morphological indexes with those of other galaxies lying within the same STIS images. Most strikingly, we find ~70% of the submillimeter galaxies to be extraordinarily large and elongated relative to the field population, regardless of optical magnitude. Comparison of the submillimeter galaxy morphologies with those of optically selected galaxies at z ~ 2-3 reveals the submillimeter galaxies to be a morphologically distinct population, with generally larger sizes, higher concentrations, and more prevalent major-merger configurations.
Wavelet transform approach to high impedance fault detection in MV networks

Application of wavelet transform technique to high impedance arcing fault detection in distribution networks is presented. Phase displacement between discrete wavelet coefficients calculated for zero sequence voltage and current signals at natural network frequency is tracked. The developed wavelet based HIF detector has been tested with EMTP-ATP generated signals, proving better performance than traditionally used algorithms and methods. The protection method proposed is efficient, robust and may be used for HIF detection independently of the network neutral point grounding mode.
Drug Use as a Risk Factor of Moral Disengagement: A Study on Drug Traffickers and Offenders against Other Persons

This study investigates the moral-disengagement strategies and influence of drug use in adolescence on 49 offenders in Italian jails, 30 of which are drug traffickers and 19 of which are offenders against other persons. A semi-structured interview was conducted to collect data on family, social and medical histories and the manner in which the deviant act was carried out, and the Moral Disengagement Scale was used to identify specific moral disengagement mechanisms. The results show that the traffickers reported higher levels of general moral disengagement, dehumanization of victims, and advantageous comparison with respect to offenders against other persons. However, the offenders who used drugs in adolescence reported higher levels of advantageous comparison with respect to offenders who did not use drugs. Studying self-regulatory mechanisms is important for enriching the literature about risk factors connected with moral disengagement and deviant behaviour committed by offenders in order to implement the promotion of effective and targeted treatment and educational strategies.
Accelerating NTRU based homomorphic encryption using GPUs

We introduce a large polynomial arithmetic library optimized for Nvidia GPUs to support fully homomorphic encryption schemes. To realize the large polynomial arithmetic library we convert polynomials with large coefficients using the Chinese Remainder Theorem into many polynomials with small coefficients, and then carry out modular multiplications in the residue space using a custom developed discrete Fourier transform library. We further extend the library to support the homomorphic evaluation operations, i.e. addition, multiplication, and relinearization, in an NTRU based somewhat homomorphic encryption library. Finally, we put the library to use to evaluate homomorphic evaluation of two block ciphers: Prince and AES, which show 2.57 times and 7.6 times speedup, respectively, over an Intel Xeon software implementation.
Screencasting: supportive feedback for EFL remedial writing students

Purpose The purpose of this paper is to explore screencasting as a computer-mediated feedback approach for Arabic native (L1) speakers taking an English as a foreign language (EFL) college remedial writing class. Design/methodology/approach This case study focused on an EFL remedial writing class consisting of eight Lebanese, Arabic L1 students at a private university in Lebanon. Students received screencast feedback through Jing® for one essay intended to assist them with subsequent revision. The multimodal screencast videos included indirect corrections, annotations, and oral commentary guided by a rubric. Students then completed a perspectives survey on screencast feedback. The instructor also led an informal group discussion to allow for further elaboration of students’ responses. Findings Students reported that screencasting’s multimodality provided for better engagement and support of learning preferences. They also perceived screencast feedback to be clearer and more useful than traditional written feedback. Research limitations/implications This study applied screencasting to address feedback challenges pertaining to clarity, learning preferences, and engagement. As this was a classroom case study, further research using a larger sample is recommended. Originality/value The aim of research into computer-mediated human feedback is to address such challenges as increasing student engagement, improving clarity, and responding to students’ preferences. Studies of screencast feedback have been few, particularly for EFL writing students. A survey of the literature indicates the need to explore contextualized classroom feedback case studies and approaches to enhance feedback.
The job demands-resources model: A meta-analytic review of longitudinal studies

ABSTRACT The job demands-resources (JD-R) model is an influential framework to understand how job characteristics foster employee well-being. Differing from the cross-sectional focus of most JD-R model reviews, this meta-analytic review uses longitudinal evidence to validate the essential assumptions within the JD-R model. We highlight two aspects: (1) The assessment of the methodological quality of the available longitudinal studies, and (2) the examination of the essential assumptions – the impact of job characteristics on well-being, and vice-versa – with meta-analytic structural equation modelling (metaSEM). We included 74 studies and evaluated their quality. Eighteen studies suffered from serious methodological shortcomings, whereas 29 studies (39%) were considered high-quality studies. Our meta-analytic structural equation models confirmed the essential assumptions simultaneously. The quality of the studies also had an influence on the goodness-of-fit indices. The models with reciprocal assumptions between job characteristics and well-being fitted the data best. The findings of this meta-analytic review suggest that the JD-R model is an excellent theoretical basis to assess employee well-being for a broad range of organisations. However, more research is needed to clarify the reciprocal relationships between job characteristics and employee well-being, as well as the different influences of challenging and hindering job demands on work engagement.
Efficient OLAP operations for RDF analytics

RDF is the leading data model for the Semantic Web, and dedicated query languages such as SPARQL 1.1, featuring in particular aggregation, allow extracting information from RDF graphs. A framework for analytical processing of RDF data was introduced in [1], where analytical schemas and analytical queries (cubes) are fully re-designed for heterogeneous, semantic-rich RDF graphs. In this novel analytical setting, we consider the following optimization problem: how to reuse the materialized result of a given RDF analytical query (cube) in order to compute the answer to another cube. We provide view-based rewriting algorithms for these cube transformations, and demonstrate experimentally their practical interest.
Urinary Bisphenol A Concentration and Angiography-Defined Coronary Artery Stenosis

Background Bisphenol A is widely used in food and drinks packaging. There is evidence of associations between raised urinary bisphenol A (uBPA) and increased incidence of reported cardiovascular diagnoses. Methodology/Principal Findings To estimate associations between BPA exposure and angiographically graded coronary atherosclerosis. 591 patients participating in The Metabonomics and Genomics in Coronary Artery Disease (MaGiCAD) study in Cambridgeshire UK, comparing urinary BPA (uBPA) with grades of severity of coronary artery disease (CAD) on angiography. Linear models were adjusted for BMI, occupational social class and diabetes status. Severe (one to three vessel) CAD was present in 385 patients, 86 had intermediate disease (n = 86) and 120 had normal coronary arteries. The (unadjusted) median uBPA concentration was 1.28 ng/mL with normal coronary arteries, and 1.53 ng/mL with severe CAD. Compared to those with normal coronary arteries, uBPA concentration was significantly higher in those with severe CAD (OR per uBPA SD = 5.96 ng/ml OR = 1.43, CI 1.03 to 1.98, p = 0.033), and near significant for intermediate disease (OR = 1.69, CI 0.98 to 2.94, p = 0.061). There was no significant uBPA difference between patients with severe CAD (needing surgery) and the remaining groups combined. Conclusions/Significance BPA exposure was higher in those with severe coronary artery stenoses compared to those with no vessel disease. Larger studies are needed to estimate true dose response relationships. The mechanisms underlying the association remain to be established.
