Managing interruptions: The role of fit between task demands and capacity

Interruptions are important phenomena in organizations, and researchers debate their effects on performance. This paper reviews the literature and argues that the degree of fit between task demands and an actor's capacity determines whether the effects of interruptions on performance are positive or negative. The fit model hypothesizes that for actors working with a capacity deficit (i.e., their capacity scarcely meet the task demands), interruptions have detrimental effects on performance. Moreover, the greater the actors' capacity, the less negative their reactions to interruptions will be. Time diaries, surveys, and archival studies were conducted among 92 public school principals in an urban school district in the eastern United States. The results support the hypothesis on the main effects of interruptions and partially support the proposed moderating effects of individual effort. The contributions of this research and its implications for future work are discussed.
Analysis of a slow-speed slotless permanent magnet synchronous generator

Department of Electrical Engineering at Tallinn University of Technology has been involved in the development of novel electrical machines for wind applications. This paper presents the analysis of the electrical parameters of a novel slow-speed slotless permanent magnet synchronous generator. Firstly, some of the design parameters are calculated and a simplified analytical mathematical model of the generator is constructed to calculate the output variables under different operational conditions. Secondly, some FEM calculations are carried out to check the validity of the analytical model. Thirdly, test results are analyzed and compared to the calculated values. Finally, the analytical model is evaluated and final output parameters of the generator are determined.

On the Importance of the Traders’ Rules for Pricing Options: Evidence From Intraday Data

Using intraday data from the KOSPI 200 Index options, we examine the pricing performance of alternative option pricing models. For comparison, we consider the Black and Scholes (Journal of Political Economy, 81, 1973, 637) model, a simple traders’ rule known as the ad hoc Black-Scholes model, the deterministic volatility model, the stochastic volatility model, and the stochastic volatility with jumps model. Contrary to the findings of Jackwerth and Rubinstein (Recovering stochastic processes from option prices), Li and Pearson (A “horse race” among competing option pricing models using S&P 500 Index options), and Kim (Journal of Futures Markets, 29, 2009, 999) using daily data, we find that the most complicated model, namely the stochastic volatility with jumps model, shows the best performance for pricing the KOSPI 200 Index options. Overall, our evidence from intraday data indicates that the traders’ rules do not dominate mathematically more sophisticated models.
EXPLORING MORAL ACTION: A CRITICAL REVIEW OF INTEGRATIVE MODELS AND SUGGESTIONS FOR FUTURE RESEARCH

In an attempt to understand the complexities of moral action, this paper undertakes a critical review of key models of ethical decision-making. Investigations begin with Rest’s (1986) model of moral action that explains the process of ethical decision-making and explores it further through subsequent descriptive studies. During the mid-1980’s and early 1990’s a number of theoretical models (e.g., Trevino, 1986; Jones, 1991) were built on the foundation of the model of moral action. These studies added a wide variety of constructs to Rest’s model in assessing the process of forming ethical intentions and ultimately translating them into behavior. Several databases were used to provide detailed information on approaches to ethical decision-making. These databases included ProQuest, JSTOR, EBSCO, PsycINFO and SSRN from which numerous peer reviewed academic journals were accessed.
Wishful sinking: Disappearing islands, climate refugees and cosmopolitan experimentation

Disappearing islands and climate refugees have become signifiers of the scale and urgency of uneven impacts of climate change. This paper offers a critical account of how sea level rise debates reverberate around Western mythologies of island laboratories. I argue that representa- tions of low-lying Oceania islands as experimental spaces burden these sites with providing proof of a global climate change crisis. The emergence of Tuvalu as a climate change 'canary' has inscribed its islands as a location where developed world anxieties about global climate change are articulated. As Tuvalu islands and Tuvaluan bodies become sites to concretize climate science's statistical abstractions, they can enforce an eco-colonial gaze on Tuvalu and its inhabitants. Expressions of 'wishful sinking' create a problematic moral geography in some prominent environmentalist narra- tives: only after they disappear are the islands useful as an absolute truth of the urgency of climate change, and thus a prompt to save the rest of the planet.
Export Promotion through Exchange Rate Policy: Exchange Rate Depreciation or Stabilization?

Exchange rate movements affect exports in two ways -- its depreciation and its variability (risk). A depreciation raises exports, but the associated exchange rate risk could offset that positive effect. The present paper investigates the net effect for eight Asian countries using a dynamic conditional correlation bivariate GARCH-M model that simultaneously estimates time varying correlation and exchange rate risk. Depreciation encourages exports, as expected, for most countries, but its contribution to export growth is weak. Exchange rate risk contributes to export growth in Malaysia and the Philippines, leading to positive net effects. Exchange rate risk generates a negative effect for six of the countries, resulting in a negative net effect in Indonesia, Japan, Singapore, Taiwan and a zero net effect in Korea and Thailand. Since the negative effect of exchange rate risk may offset, or even dominate, positive contributions from depreciation, policy makers need to reduce exchange rate fluctuation along with and possibly before efforts to depreciate the currency.
Testing for Full Insurance Using Exogenous Information

We strongly reject the full-insurance hypothesis, using testing variables that are not decision variables for the households under investigation. We find that households are not insured against changes in the unemployment rate associated with the household head's occupational category. Using this exogenous information, we also investigate the appropriateness of exogeneity assumptions on idiosyncratic variables that have been used as testing variables in the full-insurance literature. It is shown that several exogeneity assumptions made in the existing literature are potentially problematic.
Communicating Services Brands' Values Internally and Externally

This paper explores the ways that services brand values are communicated to both staff and customers. Values are communicated to employees via overt internal communications, the ripple effect, senior management example/involvement, HR activities and external communications. A number of failure factors which could hinder the communication of values to employees are identified. For consumers, values are communicated via their holistic experiences of the brand, interactions with employees, external brand communications and the tangible elements of the service offering. The results highlight the need for consistency in all brand value communications.
Molecular epidemiology and brief history of emerging adenovirus 14-associated respiratory disease in the United States.

BACKGROUND First isolated in the Netherlands in 1955 during an outbreak of acute respiratory disease (ARD) among military recruits, human adenovirus 14 (HAdV-14) has historically been considered rare. With no precedent of circulation in North America, HAdV-14 has been isolated from military and civilian cases of ARD of variable severity since 2003 in the United States. METHODS Ninety-nine isolates from military and civilian cases from different geographic locations and circulation periods were characterized by restriction enzyme analysis of viral DNA and select gene sequencing. RESULTS All examined viruses were found to be identical and to belong to a new genome type designated "HAdV-14p1" (formerly known as "14a"). Comparative alignments of E1A, hexon, and fiber gene sequences with other subspecies B2 HAdVs suggest that HAdV-14p1, like the closely related HAdV-11a, arose from recombination among similar HAdV-11 and HAdV-14 ancestral strains. A deletion of 2 amino acids in the knob region of the fiber protein is the only identified unique characteristic of HAdV-14p1. CONCLUSION The current geographic distribution of HAdV-14p1 involves at least 15 states in the Unites States. The role of the fiber mutations in the recent emergence of HAdV-14p1 ARD in North America warrants further study.
Outcome of Clonal Hemophagocytic Lymphohistiocytosis: Analysis of 32 Cases

We studied the impact of clonality, determined by analysis of Epstein-Barr virus genome termini, T-cell receptor genes and clonal chromosomal abnormality, on the clinical outcome in 32 patients with hemophagocytic lymphohistiocytosis (HLH). Of the cases studied, 23 cases were EBV-clonal, 15 cases were TCR-clonal and 7 cases were cytogenetically clonal. Thirty patients were treated with immuno-chemotherapy and/or multiagents' chemotherapy and 4 received bone marrow transplantation. All 7 cases, in which cytogenetically abnormal clones were identified, were fatal (3-year survival by Kaplan-Meier analysis; 14%, 95%CI 0–40%). None of these 7 cases received bone marrow transplantation. On the other hand, the 3-year survival of 23 clonal EBV-positive HLH cases including 4 cytogenetically abnormal cases was 64 % (95%CI: 42–84%), while that of 15 TCR-clonal cases was 53% (95%CI: 26–78%). Our observations suggest that cytogenetically abnormal cases are at extremely high risk, requiring intensive immuno-chemotherapy followed by prompt and timely allogeneic bone marrow transplantation.
The impact of HR configuration on firm performance in Singapore: a resource-based explanation

This study investigates how the characteristics of a firm's human resource practices and processes (HRPPs) are associated with firm performance. The results found that the extent to which HRPPs can be substituted by information technology or codified in employee manuals, made them easy to be imitated and were therefore associated with an attenuation of the firm's financial performance. On the other hand, constant positive investments into a firm's HRPPs were associated with enhanced firm performance. No significant relationships were found between the embeddedness of HRPPs with information technology or the uniqueness of the firm's HRPPs and firm performance. The results are explained in terms of the resource-based view of the firm.
Effects of 1‐Methyl‐4‐Phenyl‐1,2,3,6‐Tetrahydropyridine on Differentiating Mouse N2a Neuroblastoma Cells

Abstract : The effect of the neurotoxin 1‐methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine (MPTP) was investigated in mouse N2a neuroblastoma cells, induced to differentiate by serum withdrawal and addition of dibutyryl cyclic AMP, over a 24‐h period. Addition of MPTP (10 μM) during differentiation caused a change in cell morphology characterised by an inhibition of axon outgrowth, in the absence of cell death. Biochemical characterisation by western blotting revealed that MPTP had no significant effects on the levels of actin, α‐tubulin, or total heavy‐chain neurofilament (NF‐H). However, NF‐H phosphorylation appeared to increase following MPTP treatment when blots were probed with the phosphorylation state‐specific antibodies RMd09 and Ta51. In addition, indirect immunofluorescence analysis revealed an accumulation of phosphorylated NF‐H in the cell perikaryon, suggesting that altered NF‐H distribution was associated with the observed effects of MPTP on cell morphology. These changes may represent a useful in vitro marker of MPTP neurotoxicity within a simple differentiating neuronal cell model system.
Do Chinese Trust Chinese? A Study of Chinese Buyers and Sellers in Malaysia

The objective of this article is to identify the major determinants of trust in the context of industrial buying behavior among ethnic Chinese buyers and sellers in Malaysia. The authors adopt the dyadic approach to examine empirically the antecedents and consequences of trust to secure a realistic assessment of the determinants and outcome of trust. The authors employ structural equation modeling to test the proposed trust models. The study identifies perceived intention, organizational trust, strength of personal relationship, dialect fluency, and perceived similarity in cultural values as major determinants of trust among ethnic Chinese industrial buyers and sellers in Malaysia. One important managerial consideration is the need for companies to place more emphasis on the cultural and relational factors that affect trust. The results of the study confirm that the presence of trust enhances buyer–seller relationships among ethnic Chinese businesspeople. Along with satisfaction, trust between the buyer and seller dictates the probability of future interaction between the exchange parties, and thus trust is a central concept in the business exchange process.
Competition and Cooperation within a Multidivisional Firm

The strategic choice of managerial incentives is studied in a multiagent setting using a two-stage game. In the first stage, the principal chooses incentive schemes. Then, agents make their decisions. The game models the structure of multidivisional firms; divisions (agents) are managed independently but the general office (principal) monitors their performance and provides incentives. It explains the rationale for establishing either cooperation or competition across divisions if firms face Cournot competition. If divisions are linked because of technological reasons (positive spillovers), cooperation should be stimulated. If they sell substitute products (negative spillovers), competition is needed.

Competitiveness Assessment for Real Estate Enterprises in China: A Model-Procedure

China's accession to the World Trade Organization (WTO) in 2001 has allowed both domestic and overseas real estate enterprises to compete under the same market conditions. This has led to a more rigorous competition in the Chinese real estate market. Understanding this challenge is essential as it enables real estate enterprises to assess their competitiveness properly, and therefore adapt to their competition environment by applying adequate methods to improve their competitiveness. This paper presents an understanding on the applicability of various established competitiveness assessment methods. The characteristics of real estate firms are also presented with the appreciation of the Chinese environment. The study investigates the applicability of various established competitiveness assessment methods for real estate organizations in China considering the characteristics of real estate industry and the comments of the interviewees. The understanding on this applicability leads to the development of a model‐procedure for assessing the competitiveness of real estate firms. The model‐procedure employs various assessment methods in different stages in the process of examining the competitiveness of real estate businesses. The effectiveness of the application of the model‐procedure is evidenced through discussions with senior professionals. Then a case study is presented to illustrate how the model‐procedure can be applied. The findings of the study provide valuable references to study competitiveness assessment in other country's real estate industries.
Assessing stock market dependence and contagion

This paper assesses evidence of the linkages and contagion among important stock markets in Latin America (Brazil, Mexico and Argentina), Europe (UK and Germany), Asia (Japan and Singapore) and the USA from 6 September 1995 to 19 April 2013. To accomplish this task, this paper combines copula modelling with time-varying parameters and pair-copula composition of multiple dependence. The bivariate analyses show an asymmetric dependence between the stock markets as well as contagion. In addition, this work proposes a method to assess the linkages and contagion between two stock markets which takes into account the effects of a third stock market. In applying this method, conditioned on the USA market, most of the evidence of contagion between the Latin American or European markets disappears, but important dependence levels still remain.
Political contributions and analyst behavior

We show that the personal traits of analysts, as revealed by their political donations, influence their forecasting behavior and stock prices. Analysts who contribute primarily to the Republican Party adopt a more conservative forecasting style. Their earnings forecast revisions are less likely to deviate from the forecasts of other analysts and are less likely to be bold. Their stock recommendations also contain more modest upgrades and downgrades. Overall, these analysts produce better quality research, which is recognized and rewarded by their employers, institutional investors, and the media. Stock market participants, however, do not fully recognize their superior ability as the market reaction following revisions by these analysts is weaker.
Cyber-physical assessment and comparison between centralized and distributed control mode in coordinated substation voltage control

The smart grid is a typical cyber-physical system (CPS) utilizing more advanced information and communication technologies (ICTs), in which hierarchical control system (HCS) plays an essential role. However, it should be noted that for the same control function, HCSs could have multiple modes for making control decisions. They may have different cyber structures and information flows, which could lead to different levels of system reliability under cyber contingency conditions. In this paper, we describe and compare two control modes of coordinated substation voltage control (CSVC), the centralized-control and distributed-execute (CCDE) mode and the distributed mode of centralized-coordinate and distributed-control (CCDC). We first introduce CSVC's control theory, as well as its two application modes. After generating quantitative node-branch cyber-physical models for each, we perform a cyber contingency assessment and compare the results. The computation result shows that distributed mode CCDC is more reliable against cyber contingencies. By comparing their cyber networks, we identify three possible reasons for their differences and propose a simple improvement plan for CCDC, which has proved to be helpful by cyber contingency assessment results.
A Distributed Control Method With Minimum Generation Cost for DC Microgrids

This paper proposes a fully distributed control method for dc microgrids to realize power balance and bus voltage recovery without central coordination. Based on peer-to-peer communication, distributed generators and energy storage systems need only exchange information between neighbors over a sparse communication network, and hence there is a minimal communication burden. By combining the equal increment rate criteria and a subgradient algorithm, this distributed control method can efficiently regulate the bus voltage to the nominal value with minimum generation cost. In addition, the proposed method can improve the utilization of renewable energy generation via reasonable power sharing among distributed generators. Both islanded mode and grid-connected mode were simulated as case studies. The results indicate that the method is reliable, scalable, and flexible over centralized schemes. Influences of communication delays and failures of communication links are also discussed in numerical tests.
Systematic Identification for Inert Region Of a Brain from EEG

Evaluation of biomedical signals is important in the diagnosis of neurology diseases, such as dementia, in neurology through the use of electroencephalograms (EEG). While automated techniques exist for EEG analysis, it is likely that additional information can be extracted from EEG signal through the use of new methods. We describe a method for identifying inert region from EEG. This method uses EEG as input to an artificial neural network with five outputs: activity in whole region and inert region separated by four regions
Efficient Introduction of Macromolecules and Oligonucleotides into Brain Capillary Endothelial Cells Using HVJ-Liposomes

Abstract In this study, we examined the feasibility of introducing macromolecules into cultured mouse brain capillary endothelial cells (MBEC4 cells) by utilizing the hemagglutating virus of Japan (HVJ)-liposomes with fusogenic activity. We used fluorescein isothiocyanate dextran (FITC-Dextran) and FITC-labeled oligodeoxynucleotide (FITC-ODN) as models of a macromolecule and an ODN, respectively. Intracellular fluorescence appeared rapidly after the exposure of MBEC4 cells to FITC-Dextran-containing HVJ-liposomes, and remained detectable for at least 3 days. Only a control level of intracellular fluorescence was seen after treatment with FITC-Dextran alone, FITC-Dextran with empty HVJ-liposomes or FITC-Dextran-containing liposomes without fusogenic activity. In the early phase after administration (0–30 min), the introduction of FITC-Dextran into MBEC4 cells by the HVJ-liposome method resulted in a rapid and time-dependent increase of intracellular fluorescence intensity. Moreover, FITC-ODN was also introduced into MBEC4 cells by the HVJ-liposome method, although FITC-ODN alone was not introduced. These results indicate that the HVJ-liposome method is useful for the efficient introduction of macromolecules, including ODN, into brain capillary endothelial cells.
Comparison of Volatility Measures: A Risk Management Perspective

In this paper we address the issue of forecasting Value-at-Risk (VaR) using different volatility measures: realized volatility, bipower realized volatility, two-scales realized volatility, realized kernel, as well as the daily range. We propose a dynamic model with a flexible trend specification bonded with a penalized maximum likelihood estimation strategy: the P-spline multiplicative error model. Exploiting ultra-high-frequency data (UHFD) volatility measures, VaR predictive ability is considerably improved upon relative to a baseline GARCH but not so relative to the range; there are gains from modeling volatility trends and from using realized kernels that are robust to dependent microstructure noise.
