Entrepreneurial burnout: exploring antecedents, dimensions and outcomes

Purpose – The purpose of this paper is to conceptually and empirically explore the antecedents and consequences of entrepreneurial burnout – that is burnout related to the process of discovery or creation of attractive economic opportunities, the assessment of these opportunities, and the decision on the exploitation of opportunities.Design/methodology/approach – This study is a survey of entrepreneurs in New Zealand who were alumni of a university sponsored executive development course for owner‐managers of small‐ and medium‐sized enterprises.Findings – It is found that role stress is positively related to burnout and that burnout has a negative impact on organizational commitment, organizational satisfaction, and relative perceived firm performance. In addition, implications for entrepreneurs are offered with the objective of providing suggestions to mediate the negative consequences of entrepreneurial burnout.Research limitations/implications – The present study is limited by culture – the sample was d.
Understanding of BTI for tunnel FETs

We systematically investigated the NBTI degradation of Si-channel p-type tunnel FETs (pTFETs). The NBTI degradation mechanism of pTFETs is almost the same as that of pFETs. It was clarified that the NBTI degradation of pTFETs is only caused by the trap charge and the interface state degradation located in the tunneling region near the n+ source/gate edge. Furthermore, in terms of the BTI degradation of n- and p-type TFETs, although the injection sources of carriers inducing PBTI and NBTI are different, applying a drain bias corresponding to the operation conditions has an effect on the BTI lifetime improvement of n- and p-type TFETs.
A Multicultural Competencies Approach to Developing Human Capital Management

Abstract The globalisation phenomenon has been prevalent since the last decade of 20th century and remains a significant factor influencing both organisations and individuals today. Within a globalised business environment the effective management of multicultural aspects and differences has become imperative to ensure success. It is increasingly evident there is a need to develop a clear understanding of multicultural competencies in order to fully develop a strategic approach to human capital management (HCM). The adoption of a strategic approach is necessary to ensure a focus on the issues critical to success and competitive advantage including multicultural management, professional skills and knowledge management. This paper aims to identify the importance of intercultural management and the impact of globalisation upon international business.
Novel ways to sensitise gastrointestinal cancer to apoptosis

Gastrointestinal (GI) cancers are major health problems, being the most common cancers worldwide. Resistance to apoptosis is closely linked to carcinogenesis and enables malignant cells to evade therapy-induced cell death. In the recent past, the increasing understanding of molecular pathways of apoptosis has provided novel targets in cancer therapy. Several drugs, either inhibiting antiapoptotic signalling or actively inducing apoptosis in cancer cells, have already entered clinical trials. Until now, agents targeting apoptosis pathways are primarily being tested alone or in combination with chemotherapy. In the near future, personalised combination therapies will probaby be beneficial for patients with GI cancer. In this review, the current knowledge on defects in apoptosis signalling in GI cancer is summarised and the focus is on the potential clinical efficacy of apoptosis targeting agents.
Building relationship platforms in consumer markets: a value chain approach

Relationship marketing in consumer markets predicates that the relationship between the firm and its customers adds value beyond that of the mere exchange, but it does not delineate how this value is produced. Current practices in the field suggest that customers are invited to join the value chain productively, but the means offered to them are supplier specific. In this paper, we present an alternative view of the customer's value chain and we locate relationship marketing in the blending of the activities of two strategically positioned yet highly dependent systems of production and consumption. Linking the value chains of the firm and the customer we identify viable platforms for value relationships and channels that can provide hospitality to a dialogue between the two.
An Empirical Study on Business Model Elements of SMEs Based on Balanced Scorecard

Business model innovation has been a hot issue in research and practice,for it becomes an important means for firms to satisfy the complicated environment and market competition.Based on the balance scorecard theory,this paper tries to identify business model elements of SMEs through the analysis from the four perspectives: finance,customer,process and growth.The research on the data from interviews of the 11 SMEs and the results of content analysis shows that 10 elements,i.e.cost structure,revenue model,value proposition,target customer,competitive strategy,value configuration,value network,entrepreneur team,capital structure and core competence,are business model elements of SMEs.In addition,these 10 elements can be partitioned into traditional elements and specific elements.
Precise Placement of Metallic Nanowires on a Substrate by Localized Electric Fields and Inter-Nanowire Electrostatic Interaction

Placing nanowires at the predetermined locations on a substrate represents one of the significant hurdles to be tackled for realization of heterogeneous nanowire systems. Here, we demonstrate spatially-controlled assembly of a single nanowire at the photolithographically recessed region at the electrode gap with high integration yield (~90%). Two popular routes, such as protruding electrode tips and recessed wells, for spatially-controlled nanowire alignment, are compared to investigate long-range dielectrophoretic nanowire attraction and short-range nanowire-nanowire electrostatic interaction for determining the final alignment of attracted nanowires. Furthermore, the post-assembly process has been developed and tested to make a robust electrical contact to the assembled nanowires, which removes any misaligned ones and connects the nanowires to the underlying electrodes of circuit.
Application of Sequence-Specific Labeled 16S rRNA Gene Oligonucleotide Probes for Genetic Profiling of Cyanobacterial Abundance and Diversity by Array Hybridization

ABSTRACT DNA sequence information for the small-subunit rRNA gene (16S rDNA) obtained from cyanobacterial cultures was used to investigate the presence of cyanobacteria and their abundance in natural habitats. Eight planktonic communities developing in lakes characterized by relatively low algal biomass (mesotrophic) and in lakes with correspondingly high biomass (eutrophic) were selected for the study. The organismal compositions of the water samples were analyzed genetically, using multiplex sequence-specific labeling of oligonucleotide probes targeted to 16S rDNA and subsequent hybridization of the labeled probes to their respective complements spotted onto a solid support (DNA array). Ten probes were established to determine the relative abundances of the discernible cyanobacteria encountered in the selected lakes. The probes were generally specific for their targets, as determined through analyses of clone cultures. Reproducible abundance profiles were established for the lakes investigated in the subsequent analyses of natural cyanobacterial communities. The results from the genetic analyses were then compared with information obtained from standard hydrobiological and hydrochemical analyses. Qualitatively, there were relatively good correlations among the groups of organisms (Nostoc,Microcystis, and Planktothrix species) found in the different lakes. The levels of correlation were lower for the quantitative data. This may, however, be due to differences in sample processing technique. The conclusions from these comparisons are that the genetic abundance profiles may provide a foundation for separating and quantifying genetically distinct groups of cyanobacteria in their natural habitats.
Timing of late Quaternary glaciations south of Mount Everest in the Khumbu Himal, Nepal

Moraines south of Mount Everest in the Khumbu Himal were dated using optically stimulated luminescence. Clustering of ages and morphostratigraphy allowed three advances to be dated: (1) the Periche Glacial Stage (ca. 18‐25 ka), (2) the Chhukung Glacial Stage (ca. 10 ka), and (3) the Lobuche Stage (ca. 1‐2 ka). The Periche Stage is coincident with Oxygen Isotope Stage 2; the Chhukung Stage represents a late glacial or early Holocene glacial advance; and the Lobuche Stage is a late Holocene glacial advance that predates the Little Ice Age.
Reproducibility and indices of discriminatory power of microbial typing methods

When microbial strain-typing methods are compared, the most important characteristics are typeability, reproducibility, and discriminatory power. While typeability and reproducibility can be presented as numerical values, indices of discriminatory power have only recently been described. This paper examines the relationship between reproducibility and indices of discriminatory power. In an individual typing method, an inverse relationship between reproducibility and discriminatory power appears as the number of test differences required in order to distinguish between strains is increased. A method of standardizing the discriminatory power of a typing method to a predetermined reproducibility is presented. In this way the discriminatory powers of different typing methods can be compared while being standardized for the effect of reproducibility.
Deterministic K‐means secure coverage clustering with periodic authentication for wireless sensor networks

Innovative and emerging developments in sensor networks are proven to be the backbone for real‐time applications such as satellite communications, military and border area surveillance systems, health care systems, traffic monitoring systems, seismic and underwater monitoring systems, and agriculture and habitat environment systems. Coverage and clustering techniques enable the sensor network to operate in group‐based and region‐based communication and thus save the node energy. Energy‐efficient protocols save the node energy and increase the network life cycle in a resource‐constrained sensor network. Cluster head (CH) node manages and controls the operations such as network topology, coverage area, and routing paths (multi‐paths and fault‐tolerant paths) of the network. In this paper, we present deterministic K‐means secure coverage clustering (K‐SCC) with periodic authentication. The proposed protocol uses coverage clustering technique with periodic authentication between the CH node and sensor nodes to establish the secure channel in the network. Maximum cover of K nodes is maintained in the secure coverage cluster to achieve authenticated communication between the sensor nodes in the network. The proposed K‐SCC protocol is compared with the existing protocols such as deterministic‐SCC and random‐SCC protocols. Simulation results indicate that the proposed K‐SCC protocol achieves an average of 84% coverage ratio (cluster/sensor node ratio) as compared with 62% coverage ratio in the existing SCC protocols. Simulations also indicate that the proposed K‐SCC protocol consumes 20% less energy as compared with the existing SCC protocol. Copyright © 2015 John Wiley & Sons, Ltd.
A Woman's Place: A Follow-Up Analysis of the Roles Portrayed by Women in Magazine Advertisements

In the February 1971 issue of the Journal of Marketing Research, Alice E. Courtney and Sarah W. Lockeretz analyzed the roles portrayed by women in magazine advertisements in general interest publications [2]. Their study led them to conclude that advertisements appearing in April 1970 issues of 7 general publications did not present a full view of the variety of roles women actually play in American society. This article determines whether, during a time interval of 20 months, advertisers have responded to many critics who have claimed that too many advertisements have overemphasized the role of women as mere housewives in our society. A follow-up study was undertaken by examining advertisements appearing in the January 1972 issues of 7 general magazines-Life, Newsweek, The New Yorker, Saturday Review, Time, U.S. News and World Report, Reader's Digest, and New York Times Magazine Section. The first 6 general magazines examined were identical with those used in the original study. Since Look suspended publication, the only change in publications examined was the substitution of the January 2 issue of New York Times Magazine Section for Look. The same occupational and nonoccupational classifications of women were also used in the follow-up study. As in the original study, advertisements evaluated contained one or more adults.
Stereo with coplanar sensor rotation

This paper presents a new stereo configuration based on sensor rotation. Different from the traditional stereo vision system which consists of multiple cameras, our rotational stereo device is built with a single image sensor. By constraining the sensor's planar motion perpendicular to the optical axis with an offset to the axis of rotation, the visual parallax can be generated with multiple viewpoints. The stereo image pairs captured with sensor rotation are used for correspondence matching and disparity computation. A variation of multiple baseline stereo with radial configuration is proposed. It is able to provide more flexible stereo baseline settings and improve the accuracy of depth measurement. The geometric formulation and computational algorithms are developed, and a prototype range sensing device is constructed. Experimental results obtained from the real scene environment have demonstrated the feasibility of the proposed technique.
Friction: experimental determination, modeling and compensation

The friction behavior of a brush-type-DC-servomotor-driven mechanism with gearing is explored. The standard kinetic plus viscous friction model is found to describe the dominant friction behavior. In addition, a dependence of friction on position is identified and negative velocity dependence is observed at low velocities. A friction model is developed and used to precompute motion torques. The application of a precomputed torques in an open-loop fashion results in motion accurate to within a few percent. <<ETX>>
The Effect of Maker-Taker Fees on Investor Order Choice and Execution Quality in U.S. Stock Markets

Equity exchanges competing for orders are using new pricing strategies. Typically, liquidity suppliers are compensated and liquidity demanders are charged. This pricing structure is controversial because of its potential effects on investor order choice, market quality, trader welfare, and economic efficiency. I develop a theoretical model of maker-taker fees in the presence of a broker and equity exchanges and test the model empirically using order level data from SEC Rule 605. The broker charges investors a commission and endogenously chooses to route orders to a dealer or equity exchange. The exchanges keep a portion of the taker fee as profit and pass the remaining amount to the broker as a maker rebate when its order providing liquidity executes. The theoretical model predicts that as the taker fee and maker rebate increase, holding constant the amount kept as profit by the exchange: (1) the bid-ask spread declines, (2) the total trading cost increases, (3) the trader participation falls, (4) the proportion of marketable order shares rises, and (5) the non-marketable limit order fill rate increases. These implications are different from those of the model by Colliard and Foucault (2012), because my model implies that changes in the split of trading fees between liquidity suppliers and demanders affect order choice and thereby execution quality. I find empirical evidence consistent with my model’s predictions. In particular, as the taker fee and maker rebate increase, holding constant the amount kept as profit by the exchange: (1) the bid-ask spread declines, (2) the trader participation falls, (3) the proportion of marketable order shares rises, and (4) the non-marketable limit order fill rate increases.
Tempering by Subsampling

In this paper we demonstrate that tempering Markov chain Monte Carlo samplers for Bayesian models by recursively subsampling observations without replacement can improve the performance of baseline samplers in terms of effective sample size per computation. We present two tempering by subsampling algorithms, subsampled parallel tempering and subsampled tempered transitions. We provide an asymptotic analysis of the computational cost of tempering by subsampling, verify that tempering by subsampling costs less than traditional tempering, and demonstrate both algorithms on Bayesian approaches to learning the mean of a high dimensional multivariate Normal and estimating Gaussian process hyperparameters.
Complete Sequence and Gene Organization of the Nosema heliothidis Ribosomal RNA Gene Region

ABSTRACT. By sequencing the entire ribosomal RNA (rRNA) gene region of Nosema heliothidis isolated from cotton bollworm (Helicoverpa armigera), we showed that its gene organization is similar to the type species, Nosema bombycis: the 5′‐large subunit rRNA (2,490 bp)‐internal transcribed spacer (192 bp)‐small subunit rRNA (1,232 bp)‐intergenic spacer (274 bp)‐5S rRNA (115 bp)‐3′. We constructed two phylogenetic trees, analyzed phylogenetic relationships, examined rRNA organization of microsporidia, and compared the secondary structure of small subunit rRNA with closely related microsporidia. The latter two features may provide important information for the classification and phylogenetic analysis of microsporidia.

Immune Surveillance Properties of Human NK Cell-Derived Exosomes

Exosomes are nanovesicles released by normal and tumor cells, which are detectable in cell culture supernatant and human biological fluids, such as plasma. Functions of exosomes released by “normal” cells are not well understood. In fact, several studies have been carried out on exosomes derived from hematopoietic cells, but very little is known about NK cell exosomes, despite the importance of these cells in innate and adaptive immunity. In this paper, we report that resting and activated NK cells, freshly isolated from blood of healthy donors, release exosomes expressing typical protein markers of NK cells and containing killer proteins (i.e., Fas ligand and perforin molecules). These nanovesicles display cytotoxic activity against several tumor cell lines and activated, but not resting, immune cells. We also show that NK-derived exosomes undergo uptake by tumor target cells but not by resting PBMC. Exosomes purified from plasma of healthy donors express NK cell markers, including CD56+ and perforin, and exert cytotoxic activity against different human tumor target cells and activated immune cells as well. The results of this study propose an important role of NK cell-derived exosomes in immune surveillance and homeostasis. Moreover, this study supports the use of exosomes as an almost perfect example of biomimetic nanovesicles possibly useful in future therapeutic approaches against various diseases, including tumors.
Gaining competitive advantage through customer value oriented management

Within the customer value literature there is a lacuna of theoretical frameworks and models that underlie consumers’ overall product valuation. This paper addresses this limitation and presents a model integrating consumer values, product benefits, and various costs of consumption. In the proposed model, benefits and costs are defined in terms of consumers’ perceptions in the activities of acquisition, consumption, and maintenance, as well as consumers’ expectation of value satisfaction before buying.
A matrix discrete empirical interpolation method for the e ffi cient model reduction of parametrized nonlinear PDEs : application to nonlinear elasticity problems ⇤

When using Newton iterations to solve nonlinear parametrized PDEs in the context of Reduced Basis (RB) methods, the assembling of the RB arrays in the online stage depends in principle on the high-fidelity approximation. This task is even more challenging when dealing with fully nonlinear problems, for which the global Jacobian matrix has to be entirely reassembled at each Newton step. In this paper the Discrete Empirical Interpolation Method (DEIM) and its matrix version MDEIM are exploited to perform system approximation at a purely algebraic level, in order to evaluate both the residual vector and the Jacobian matrix very efficiently. We compare different ways to combine solution-space reduction and system approximation, and we derive a posteriori error estimates on the solution accounting for the contribution of DEIM/MDEIM errors. The capability of the proposed approach to generate accurate and efficient reducedorder models is demonstrated on the solution of two nonlinear elasticity problems.
Macro-Economic Forces and Indian Stock Market: An Empirical Relation

Movements in the stock market can be quite volatile and sometimes movements in share prices can seem divorced from economic factors. However, there are certain underlying factors which have a strong influence over the movement of share prices and the stock market in general. Within the framework of a Correlation Coefficient Model, we examine whether a number of macroeconomic variables influence stock prices in Indian Stock Market. A Correlation analysis is applied in order to model the long-term relationship between GDP, Exchange rates, Inflation Rate, Gross Domestic Savings, Capital formation/Investment and SENSEX in the Indian Capital market. This study being a descriptive in nature examines the major economic indicators and the Indian stock market represented by BSE Sensex. During the past sixteen years there is down in the Indian stock market and Foreign portfolio investment patterns, consequent upon several changes affecting the Indian economy, like the technology slowdown, common wealth scam and political instability to name a few. However the researcher found that the Depreciation in the Rupee against the Dollar has lead to decrease in the share prices. It has a negative impact on the stock prices and Increase in the Inflation rate has led to decrease in the share prices. The effect of changes of inflation rate on BSE SENSEX is very less. However a few of scrip have not been affected by Inflation. The researcher concluded that Other than the above two economic factors there are other factors such as Interest Rate, Market Sentiments, Global factors, performance of company etc.which affect the share prices of Indian Stock Market
