Job Stress with Supervisor’s Social Support as a Determinant of Work Intrusion on Family Conflict

Purpose : The primary objective of this study is to examine the influence of supervisor’s social support in the correlation between job stress and work intrusion on family conflict. Design/methodology/approach: A survey method was employed to gather survey questionnaires from academic staff in a Malaysian government university in Borneo. Findings: The outcomes of SmartPLS path model showed three major findings: first, supervisor’s social support does act as an important moderating variable in the relationship between role ambiguity and work intrusion on family conflict. Second, supervisor’s social support does not act as an important moderating variable in the relationship between role conflict and work intrusion on family conflict. Third, supervisor’s social support does not act as an important moderating variable in the relationship between role overload and work intrusion on family conflict. In sum, supervisor’s social support does act as a partial moderating variable in the hypothesized model. Practical implications: The findings of this study can be used as guidelines by management to overcome job stress problems through updating the content and methods of stress management training program, strengthening work groups and group cohesiveness in executing job, improving work-life balance programs to reduce the employee physiological and psychological stresses, revisiting the existing job designs based on the qualifications and expectations of individual employees, and revising compensation and benefits policies and procedures to cover stress-related disorder diseases, and activating internal employee assistance programme in order to help employees and their families with problems arising from both work-related and external resources. If these suggestions are given highly attention this may increase the capability of employees to enhance the performance of institutions of higher learning. Originality/value: The role of supervisor’s social support in influencing the effect of job stress on family conflict is commonly investigated in Western countries, but it has not been thoroughly studied in the context of this study.
Synchronization of forced reactively coupled van der Pol oscilators

Synchronization of forced reactively coupled van der Pol oscillators is investigated in the phase approximation. We discuss essential features of the reactive coupling. Bifurcation mechanisms for the destruction of complete synchronization and possible quasi-periodic regimes of different types are revealed. Regimes when autonomous oscillators demonstrate frequency locking and beating regimes with incommensurate frequencies are considered and compared.
Context storage using NoSQL

With the ubiquity and pervasiveness of mobile computing, together with the increasing number of social networks, end-users have learned to live and share all kinds of information about themselves. As an example, Facebook reports that it has currently 500 million active users, 200 million of which access its services on mobile systems; moreover, users that access Facebook through mobile applications are twice as active as non-mobile users, and it is used by 200 mobile operators in 60 countries [1]. More specific mobile platforms such as Foursquare, which unlike Facebook only collects location information, reports 6.5 million users worldwide, and also has a mobile presence (both with a web application and iPhone / Android applications) [2]. Contextaware architectures intend to explore this increasing number of context information sources and provide richer, targeted services to end-users, while also taking into account arising privacy issues. While multiple context management platform architectures have been devised [3], this paper focuses primarily on ContextBroker-based architectures, such as the ones proposed in the projects Mobilife [4] and C-Cast [5]. More specifically, it focuses on the context management platform XCoA [6]. This platform uses XMPP for its main communication protocol, and publishes context information in a Context-Broker. This context information is provided by Context-Agents, such as mobile terminals, sensor networks and social networks. Due to the nature of the XMPP protocol, the context information is provided in XML form. This paper proposes the usage of a NoSQL storage system for the purpose of context information storage and retrieval in an XMPP broker-based context platform such as XCoA, together with a full-text searching engine. Through a comparison made through prototypes, the paper clearly demonstrates the advantages of NoSQL storage systems applied to the area of Context Management.
Agro-food economics as culture economics: some inceptive reflections

The main objective of our work is to discuss the approach of economics of culture as an analytical perspective on agri-food sector. Then, the question we try to satisfy is which could difficulties researchers might encounter in such a perspective. In the next section we considered some doctrinal antecedents and theory literature. The third one is dedicated to some approach to areas of serious mismatching between mainstream theory economics and cultural standpoint, namely in the light of agro-food economy characteristics. The last paragraph illustrates the concluding remarks.
A Proposed Validation Method for a Benchmarking Methodology

The aim of this paper is to describe a meaning to validate a previously proposed benchmark method targeted at NoSQL databases. The method described here is based on a statistical analysis of the results given by the benchmarking software. The reason for proposing such a validation method is the opinion of the author that any benchmarking methodology should be both based on a rigorous algorithm and verified in a thorough way (by validation and by testing) before practical use.
Optimal design of orders of discrete fractional Fourier transforms for sparse representations

This paper proposes to use a set of discrete fractional Fourier transform (DFrFT) matrices with different rotational angles to construct an overcomplete kernel for sparse representations of signals. The design of the rotational angles is formulated as an optimization problem as follows. The sum of the L1 norms of both the real part and the imaginary part of transformed vectors is minimized subject to different values of the optimal rotational angles. In order to avoid all the optimal rotational angles within a small neighbourhood, constraints on the sum of the L1 norms of both the real part and the imaginary part of the product of the individual optimal DFrFT matrices and training vectors being either stationary or nondifferentiable are imposed. Solving this optimization problem is very challenging not only because of the nonsmooth and the nonconvex nature of the problem, but also due to expressing the optimization problem in a nonstandard form. To solve the problem, first it is shown in this paper that this design problem is equivalent to an optimal sampling problem as follows. The absolute sum of the L1 norms of both the real part and the imaginary part of the frequency responses of a set of filters at the optimal sampling frequencies is minimized subject to similar constraints. Second, it is further shown that the optimal sampling frequencies are the roots of a set of harmonic functions. As the frequency responses of the filters are required to be computed only at frequencies in a discrete set, the globally optimal rotational angles can be found very efficiently and effectively.
The automorphisms of Petit’s algebras

ABSTRACT Let σ be an automorphism of a field K with fixed field F. We study the automorphisms of nonassociative unital algebras which are canonical generalizations of the associative quotient algebras K[t;σ]∕fK[t;σ] obtained when the twisted polynomial f∈K[t;σ] is invariant, and were first defined by Petit. We compute all their automorphisms if σ commutes with all automorphisms in AutF(K) and n≥m−1, where n is the order of σ and m the degree of f, and obtain partial results for n<m−1. In the case where K∕F is a finite Galois field extension, we obtain more detailed information on the structure of the automorphism groups of these nonassociative unital algebras over F. We also briefly investigate when two such algebras are isomorphic.
Weed species in synantropic flora of Novi Sad.

Ruderal or syntrophic flora and vegetation are the most dynamic floristic-vegetation complex and an integral part of antropogenic environment. On one side the influence of antropogenic factors and on the other a variety of climate, topografic, geological and soil characteristics contribute to highly pronounced diversity of a weed flora. The presence of antropogenic influences have crucial importance of the emergence, development and distribution of ruderal flora and ruderal vegetation making the biotops very dynamic and unstable habitats. Horticulture has a long tradition in the city of Novi Sada which is located in the region of intensive agricultural production as a port center with international transport links and consequently is the most exposed to the introduction of new species. According to the existing data Novi Sad has the largest number of invasive species (59,7%) in Vojvodina, which indicates a need to produce a syntrophic inventory of its flora in order to list both native and introduced species. Phytogeographical analysis has been performed on syntrophic flora whith special emphasis on the analysis of the origin of introduced plant species. Furthermore, the range of life forms that indicates the caracter of antropogenically altered phytocenosis has been determined.
Soldering-based easy packaging of thin polyimide multichannel electrodes for neuro-signal recording

We propose a novel packaging method for preparing thin polyimide (PI) multichannel microelectrodes. The electrodes were connected simply by making a via-hole at the interconnection pad of a thin PI electrode, and a nickel (Ni) ring was constructed by electroplating through the via-hole to permit stable soldering with strong adhesion to the electrode and the printed circuit board. The electroplating conditions were optimized for the construction of a well-organized Ni ring. The electrical properties of the packaged electrode were evaluated by fabricating and packaging a 40-channel thin PI electrode. Animal experiments were performed using the packaged electrode for high-resolution recording of somatosensory evoked potential from the skull of a rat. The in vivo and in vitro tests demonstrated that the packaged PI electrode may be used broadly for the continuous measurement of bio-signals or for neural prosthetics.
New Taxonomies for Limited Dependent Variables Models

We establish a `map' for describing a wide class of Limited Dependent Variables models much used in the econometric literature. The classification system, or language, is an extension of Amemiya's typology for tobit models and is intended to facilitate communication among researchers. The class is defined in relation to distributions of latent variables of an arbitrarily high dimension; the region of support can be divided into an arbitrary number of subsets, and the observation rules in each subset can be any combination of the observed, censored, and missing status. Consistent labeling is suggested at different levels of detail.
MOLECULAR SIGNALLING SAGA IN TUMOUR BIOLOGY

‘Cancer’ is a broad term used for malignant tumours that has spread throughout the body. The initiation and progression of tumour is driven by complex signaling pathway that can be majorly categorized as oncogenic signal and anti-oncogenic signal. The development of tumour is regulated by abnormal oncogenic signal. The therapy of tumour is designed via targeting the blockage of oncogenic signal or activation of anti-oncogenic signal. This review is an illustration of different signaling pathway involved in tumour biology and the timeline historical review of progress made in the field of tumour biology.
A P ] 2 0 Ju l 2 00 9 Rough solutions for the periodic Korteweg – de Vries equation

We show how to apply ideas from the theory of rough paths to the analysis of low-regularity solutions to non-linear dispersive equations. Our basic example will be the one dimensional Korteweg– de Vries (KdV) equation on a periodic domain and with initial condition in FLα,p spaces. We discuss convergence of Galerkin approximations, a modified Euler scheme and the presence of a random force of white-noise type in time.
Evaluation of a Patient Education Program for Patients with Non-Insulin Dependent Diabetes (Type II)

The purpose of this study was to evaluate a group outpatient program for patients with non-insulin dependent diabetes (Type II). It endeavoured to establish whether at the completion of a patient education program, and again at the 3 month follow-up period, the patients were complying with : (a) the recommended dietary plan, (b) the exercise program, and (c) were monitoring blood glucose levels at home, as evidenced by weight loss and metabolic control of their diabetes. The study also investigated factors influencing non-compliance. The theoretical rationale used for this study was Pender's Health Promotion Model, which theorises that health-promoting behaviour is motivated by a desire for increased well-being and quality of life. Health-promoting ' behaviours are adopted in order to change behaviour to achieve an improved health status. The study sample was a convenience sample of 24 outpatients who enrolled in and completed an education program, and who volunteered to participate in the study. The study used a pretestjposttest design with a 3 month follow-up, wjth a pretest prior to commencing the education program, the posttest on completion of the program, and a follow-up 3 months later. Instrumentation included: a questionnaire to measure dietary and exercise compliance, blood glucose monitoring, and factors influencing non-compliance; a blood glucose
Optimal Control of an Influenza Model with Seasonal Forcing and Age Structure

This study considers an optimal intervention strategy for influenza outbreaks. Variations in the SEIAR model are considered to include seasonal forcing and age structure, and control strategies include vaccination, antiviral treatment, and social distancing such as school closures. We formulate an optimal control problem by minimizing the incidence of influenza outbreaks while considering intervention costs. We examine the effects of delays in vaccine production, seasonal forcing, and age-dependent transmission rates on the optimal control and suggest some optimal strategies through numerical simulations.
Analysis of Evolution and Research Focus in Chinese Psychiatry Field

While a large number of representative scientists devoted in the field of psychiatry, their scientific research productions came into being. We selected all related 982 documents from Science Citation Index Expanded (SCI-Expanded) in Web of Science during from 1983 to 2012 and utilized the information visualization software (CiteSpace Ⅲ ) to conduct co-citation and hierarchal clustering analysis to mapping knowledge domain of development and evolution. From the evolution in Chinese psychiatry field, there were divided into two stages. Through hierarchal clustering analysis, the research foci in Chinese psychiatry field were mainly mental health service, diagnostic criteria of mental disorder and psychopathology and neuropathology of mental disorder, ect. Based on the results, the evolution and research foci in Chinese psychiatry field not only help researchers find the research direction and the gap with the world, but also offer reasonable suggestions as the basis of making polices to guide psychiatry research and provide scientific evidences on preventing and curing mental disorder effectively.
Inter-organizational proximity in the context of logistics - research challenges

Background: One of major areas of modern research econnected with management issues covers interorganizational networks (including supply chains) and cooperation processes aimed at improvement of the effectiveness of their performance to be found in such networks. The logistics is the main factor responsible for effectiveness of the supply chain. A possible and a quite new direction of research in the area of the performance of processes of the interorganizational cooperation is the proximity hypothesis that is considered in five dimensions (geographical, organizational, social, cognitive, and institutional). However, according to many authors, there is a lack of research on supply chains conducted from the logistics point of view. The proximity hypothesis in this area of research can be seen as a kind of novum. Therefore, this paper presents the proximity concept from the perspective of the management science, the overview of prior research covering the inter-organizational proximity with supply chain from the logistics point of view as well as the possible future directions of the empirical efforts. Methods: The aim of this paper is to present previous theoretical and empirical results of research covering interorganizational proximity in logistics and to show current and up-to-date research challenges in this area. The method of the critical analysis of literature is used to realize the goal constructed this way. Results: Knowledge about the influence of the inter-organizational proximity on the performance of supply chains is rather limited, and the research conducted so far, is rather fragmentary and not free of limitations of the conceptual and methodological nature. Additional rationales for further research in this area include knowledge and cognitive gaps indentified in this paper. According to authors the aim of future empirical research should be as follows: (1) unification and update of used conceptual and methodological approaches in research on the proximity in supply chains, (2) testing of theoretical hypotheses with attention paid to importance of the proximity for supply chains taking into account the significant heterogeneity of this form of inter-organizational cooperation, and (3) recognizing the role of the interorganizational proximity for the practice of supply chain management and for the realization of the integration function of the logistics. Conclusions: There is a shortage of scientific research (both in the theoretical and empirical dimension) explaining the importance of the proximity hypothesis for the performance of supply chains. Additionally, there are interesting gaps in existing scientific output, connecting the logistics output (effectiveness and performance of supply chains) and economic geography (the proximity hypothesis). Closing these gaps should increase our understanding of the supply chains performance and, therefore, this will be the area of further research of authors.
STRATEGIC RESPONSES OF AGA KHAN UNIVERSITY HOSPITAL TO CHANGES IN THE EXTERNAL ENVIRONMENT

Organizations without exception are environment serving and environment dependent. They are therefore open systems that interact with their environment to secure the resources necessary for survival, adaptation and growth. Organizations policies and incentives depend on their role and functions as well as the beliefs and experiences of those who interact with them. Health care industry in Kenya is facing unprecedented trials due to the rapid external environmental changes occurring during recent years. Survival and viability of hospitals today demands appropriately deployed strategic management. Unpredictable and constantly changing competitive environment, Political, economic, social, technological and legal triggers influence hospitals management forcing them to seek entrepreneurially flexible yet stable corporate strategies. How an organization responds to changes w'ithin its environment determines its success in the industry and constitutes its strategic responses. This study discusses the strategic responses that the Aga Khan University Hospital Nairobi (AKUH, N) has adopted to counter the changes in their external environment. The research was an in-depth case study with the objective of establishing what strategic responses the AKUH, N has adopted to counter the changes in the changing external environment. The study was conducted by carrying out in-depth interviews with the AKUH, N management by the use of semi-structured interview guide to obtain primary data. Secondary data was collected from public reports and hospital’s own announcements and documents.
On the potential high acid deposition in northeastern China

There is an acid deposition conundrum in China: contrary to conventional wisdom, extremely high ambient sulfate concentrations in northeastern China are not always accompanied by correspondingly high acidities. To investigate this discrepancy, data from two independent sets of in situ field measurements were analyzed along with Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) satellite observations and Model for Ozone and Related chemical Tracers (MOZART) chemical transport model calculations. The field measurements included soluble aerosol ion concentrations and pH and particulate data from 11 cities, as well as pH measurement data from 74 sites in China. This study explores the basis for and the impacts of the large discrepancy in northeastern China between the major acidity precursors (SO2 and NOx) and measured acidity levels as indicated by pH values. There are extremely high SO2 emissions and ambient concentrations in northeastern China, while the corresponding acidity is unusually low (high pH) in this region. This is inconsistent with the usual situation where high‐acidity precursor pollutants result in low pH (high acidity) values and acid rain conditions. In other regions, such as southern China and the United States, high SO2 concentrations are typically well correlated with high acidities. Using measured soluble particle measurements (including both positively and negatively charged ions), it is seen that there are high values of alkaline ions in northeastern China that play an important role in neutralizing acidity in this region. This result strongly suggests that the high alkaline concentrations, especially Ca2+, increase warm season pH values by about 0.5 in northern China, partially explaining the inconsistency between sulfate concentrations and acidity. This has a very important implication for acid rain mitigation—especially in northeastern China. However, there are additional issues pertaining to the precursor‐acidity relationship that need further investigation. Why is it that the reduction in acidity due to the alkaline ions is only significant in summer? During winter, the measured alkaline ions play a much smaller role in explaining the discrepancy. The measured alkaline ions in this study were mostly obtained from particles in the PM2.5 range. However, the size of calcium particles is typically much larger—extending well beyond 2.5 µm—and so a significant amount of calcium may be underestimated by PM2.5 measurements alone. The under‐sampling of calcium particles is further exacerbated in that the sampling protocol excluded particle (and soluble ion and pH) measurements during dust storms. This all leads to the need for an improved understanding of pollutant‐ion‐particulate interactions in China, and their role in explaining the counter‐intuitive conclusion that dust mitigation strategies in China could have the unintended consequence of exacerbating acid rain conditions.
