Information Technology Failure and Firm Value: Exploring the Impact of Corporate Social Responsibility

Research on the relationship between Corporate Social Responsibility (CSR) and firm value has revealed a strong positive correlation. Further, researchers have found that social responsibility supports crisis management of certain externally-generated negative events. While these findings have proven both interesting and useful, questions remain regarding the impact of social responsibility when an unexpected information technology (IT) failure occurs. This exploration considers the effect of CSR on the market’s response to an IT failure. Thus, we offer a theoretical framework which can be applied in future research to advance CSR and IT failure literatures.
Beta-adrenergic blockade and myocardial perfusion in coronary artery disease: differential effects in stenotic versus remote myocardial segments.

UNLABELLED Beta-adrenergic blocking agents are widely used in coronary artery disease (CAD), although their impact on myocardial blood flow (MBF) and coronary flow reserve (CFR) remains unclear. We studied the effect of long-term beta-blocker treatment (carvedilol or metoprolol) on coronary microcirculation in CAD patients using PET. METHODS Regional and global resting and adenosine-induced hyperemic MBF and CFR were measured with 13N-ammonia and PET in 36 CAD patients before and after 12 wk of oral therapy with either carvedilol, 50 mg/d, or metoprolol, 100 mg/d. RESULTS Beta-blockade decreased global resting MBF in proportion to cardiac work (from 0.86 +/- 0.20 to 0.77 +/- 0.14 mL/min/g, P < 0.05) without affecting global hyperemic flow. Hyperemic MBF was significantly lower in stenosis-dependent segments than in remote segments (1.76 +/- 0.64 vs. 2.04 +/- 0.67 mL/min/g, P < 0.05) at baseline but was comparable in both after treatment (2.02 +/- 0.68 vs. 1.90 +/- 0.78 mL/min/g, P = not statistically significant [NS]), resulting in a significant CFR increase in stenotic segments (+15%, P < 0.05) but not in remote segments (+9%, P = NS). CONCLUSION The beneficial effect of beta-adrenergic blockade can be explained by the reduction in oxygen consumption (= decreased demand) but also by a modest improvement in vasodilator capacity (= increased supply). The improvement in CFR is found predominantly in stenosis-dependent rather than remote segments.

An active PFC boost converter topology for power factor correction

This paper introduces a single-stage active power factor correction (PFC) AC-DC converter which provides almost unity power factor and minimizes the THD to 7.4 %. For a constant DC output voltage a single phase diode bridge rectifier with a large output capacitor is considered in this paper. This standard topology has a shortcoming of introducing lower order harmonics and become cause of poor power factor, which needs to be improved. MATLAB Simulation software is used to simulate a simulation model of 350 W output for both passive and active PFC methods. Simultaneously, the experimental prototype for 350W/390V output with active PFC method is designed and experimental results are verified.
A direct mail customer purchase model

A general customer purchase model is presented for segmenting direct marketing customer files for direct mailings. The model specifies the functional relationships among the traditional recency, frequency, and monetary value (RFMV) variables. Because of the generic nature of the model, it can be used by different direct marketing businesses for a variety of different customer mailings. Strategic implications of the model are discussed for: a) defining active versus inactive customers, b) selecting customers for special mailings, c) comparing multiple customer lists for a single company, d) an overall company purchase score for a company with multiple programs/customer files, and e) product purchase scores for special product offers.
Determinants and consequences of consumer satisfaction with self‐service technology in a retail setting

Purpose – The purpose of this study is to investigate the antecedents and consequences of consumer satisfaction with the use of self‐service technology (SST) in a retail setting.Design/methodology/approach – In cooperation with a survey firm, a total of 424 respondents were collected from among consumers who had experience of using multimedia kiosks at convenience stores in Taiwan. The conceptual model was tested by using structural equation modeling.Findings – The results show that perceived usefulness and perceived enjoyment both, initially, influence perceived control and convenience and then affect consumer satisfaction, which in turn has an impact on consumer continued behavior intention. In addition, perceived enjoyment is found to enhance consumer satisfaction, but perceived usefulness is not.Originality/value – This paper proposes a conceptual model to synthesize the essence of the ECM‐IT model and two important incentives in self‐service (i.e. perceived control and convenience) in order to provid.
6MW solar plant integration feasibility study: Bonaire island case study

The power supply on Bonaire is characterized by a high penetration of wind energy. Currently 5 diesel generators (total capacity 14MW) and 12 wind turbines (total capacity 10.8MW) operated by ContourGlobal generate electricity for Water and Electricity Bonaire (WEB). To meet future power demand increase, WEB has the ambition to connect a 6MW centralized solar plant to their system, thereby further increasing their renewable power generation in the island's energy mix. This paper studies the system impact of adding a 6MW centralized solar plant on the existing system and highlights the associated operational constraints.
The Effect of Directors’ and Officers’ Liability Insurance on Stock Investors’ Perceptions of Earning Quality

Using the earnings response coefficients (ERC hereafter) as a proxy for stock investors’ perceptions of earnings quality, this study examines the effect of directors’ and officers’ liability insurance (D&O insurance hereafter) on the ERC. Using publicly-available D&O insurance data for public firms in Taiwan from 2008 to 2010, we employ an endogenous binary treatment model and other methods to control self-selection bias on the estimation of relationship between D&O insurance and ERC. The empirical results show that firms with D&O insurance have lower ERC than those without D&O insurance. In addition, we find that firms with higher D&O insurance coverage have lower ERC and firms with higher abnormal D&O insurance coverage will further deteriorate the ERC. These results imply that stock investors believing the purchase of D&O insurance may increase the risk of moral hazard from directors and officers, as it is not conducive to earnings quality, and their earnings information on responses to stock prices will thereby be reduced.
P‐glycoprotein and multidrug resistance‐associated protein 2 are oppositely altered in brain of rats with thioacetamide‐induced acute liver failure

P‐glycoprotein (P‐GP) and multidrug resistance‐associated protein 2 (MRP2) are involved in transport of many drugs across blood–brain barrier (BBB). The function and expression of P‐GP and MRP2 may be modulated by different pathologies. Acute liver failure (ALF) was reported to impair BBB function, resulting in the increased BBB permeability.
An Explicit Construction of Optimal Streaming Codes for Channels with Burst and Arbitrary Erasures

This paper presents a new construction of error correcting codes which achieves optimal recovery of a streaming source over a packet erasure channel. The channel model considered is the sliding window erasure model, with burst and arbitrary losses, introduced by Badr et al. Recently, two independents works by Fong et al. and Krishnan and Kumar have identified optimal streaming codes within this framework. In this paper, we introduce streaming codes when the rate of the code is at least 1/2. Our proposed construction is explicit and systematic, uses off-the-shelf maximum distance separable (MDS) codes and maximum rank distance (MRD) Gabidulin block codes as constituent codes and achieves the optimal error correction. It presents a natural generalization to the construction of Martinian and Sundberg which tolerates an arbitrary number of sparse erasures. The field size requirement which depends on the constituent MDS and MRD codes is also analyzed.
Antecedents of brand preference for mobile telecommunications services

Purpose – This paper aims to report on a study into the antecedents of consumer brand preference, in the context of telecommunications service brands in Jordan.Design/methodology/approach – A questionnaire‐based survey was used to gather attitudes towards brand preference and its antecedents in the context of mobile telecommunications service providers in Jordan. The questionnaire was distributed, in Arabic, to university students in Jordan, a group selected as being active users of mobile phone services; 648 completed questionnaires were received. Data were entered into SPSS. Principal component analysis (PCA) was applied to identify the antecedents of brand preference. Multiple regression was conducted in order to investigate the relative impact of the identified factors on brand preference.Findings – Factor analysis identified 11 antecedents of brand preference; these can be theoretically clustered into three groups: awareness antecedents (controlled communication (advertising), and uncontrolled commun.
Convergence of Shielded Room Error Analysis Using Image Antenna Theory

The near-zone magnetic field radiated by a small-loop antenna has been used for the sensitivity test of a radio receiver. When an external interference field exists around the antennas, the test must be carried out in a shielded room. The formulas to estimate the effect of the room on the standard magnetic field are derived by using the image antenna theory. These formulas are expressed in the form of an infinite series. The states of the convergence of the formulas are compared with those already derived from the reciprocity theorem. The convergence for the image antenna theory is more rapid when the ratio of the loop spacing to the wavelength is smaller and the ratio of the size of the shielded room to the wavelength is larger, while the one for the reciprocity theorem is more rapid under reverse conditions.
Implementation of complete AC servo control in a low cost FPGA and subsequent ASSP conversion

A process of creating AC servo drives without software programming has been created using FPGA technology At the core of this design is a flexible motion control engine, designed using Verilog HDL language and implemented on an industry standard FPGA. The resulting portable design is converted into a unique servo-on-a-chip ASSP (application specific standard product) for use in cost sensitive applications. Functionality includes field orientation control (FOC), closed loop velocity control, (optionally) closed loop position control with notch filter/feedforward functions, incremental encoder, space vector modulation (SVM), and host communication modules. The system also supports direct digital interface to high voltage (600 V) bus systems by utilizing monolithic gate driving and current sensing ICs which are insensitive to high common mode offset and dV/dT. The FOC executes quickly in dedicated parallel hardware without the timing overhead penalty of a serial processor core. Fast control update is thus achieved which yields high bandwidth torque control exceeding 5 kHz at -3dB. The focus of this paper is efficient use of hardware (FPGA) resources to create a powerful, yet open architecture for AC servo control development, including performance analysis and comparison against conventional software based solutions. Test results based on 1 kW servo system are discussed, which are included for system verification.
A MATHEMATICAL MODEL FOR FINANCIAL INNOVATION: EMPIRICAL EVIDENCE FROM FINANCIAL MARKETS

Financial innovation is an important research topic modern economics. Financial innovation is an ongoing process where new financial products, services and procedures are created and it concerns important financial factors such as the regulatory restrictions, the relationship between financial innovation and the functionality of financial markets, the inefficiency of markets promoted by globalization and unexpected changes of economic status and financial intermediary. The previous literature that deals with financial innovation is relatively constrained compared to the significance of the issue, which is a surprise considering the relative abundance of such research on other sectors of finance and economics. The consequences of financial innovations concern the functional framework of capital markets, the microeconomic and the macroeconomic functional frameworks. This thesis studies the influence of diffusion of financial innovation to market participants‟ frictions and their values, through a theoretical, mathematical and empirical framework. We derive a novel measure of the influence of financial innovation to the market participants based on their correlation friction patterns. The main objective is to highlight a number of aspects and dimensions of this field. In particularly, we aim to present: i) the theoretical framework on the role of financial innovation at the financial structure (the fundamental generating root causes and the effects on the function of financial markets, etc), and ii) the parameterization of the influence of financial innovation to market participants through a mathematical and econometric framework based on the participants‟ minimum need for change, the diffusion rate and time parameter. We undertake an extensive empirical analysis about the influence of introduction and diffusion of a financial innovation to market participants. The findings lead us to the conclusion that the parametric function, which is followed in order to show the influence of diffusion of financial innovation, has a statistically significant impact on returns and volatility of financial and economic indices.
Foreign-based competition and corporate diversification strategy

Since the mid-1980s U.S. domestic firms have faced significant increases in foreign-based (i.e., import) competition as reductions in barriers to international commerce have resulted in markets and industries becoming increasingly global. Despite the growing and widespread importance of foreign-based competition, the influence that such competition may exert on corporate diversification strategy is a question largely overlooked in the strategic management literature. This paper examines the impact of foreign-based competition in a firm's core business on both the level and nature of a firm's diversification strategy at the corporate level in a panel dataset of U.S. firms over the period 1985–94. Our findings provide the first evidence that increased foreign-based competition is indeed a statistically significant factor explaining both the reduced business-level diversity and the increased strategic focus of U.S. firms that has been widely perceived over the past two decades.

Discontinuation of anticonvulsant therapy in children with partial epilepsy

Article abstract To evaluate when it is possible to discontinue anticonvulsant treatment in children with cryptogenic partial epilepsy, the authors studied 89 epileptic children divided into two groups: Group A, 45 children whose therapy was discontinued after 1 year from the last seizure; and Group B, 44 children whose therapy was stopped after 2 years from the last seizure. After 5 years of follow-up, the recurrence rate was similar in the two groups of patients (Group A, 28.8%; Group B, 25%). It is safe to discontinue the anticonvulsant therapy in children with cryptogenic partial epilepsy who were seizure free for only 1 year.
Non-Negotiables of Gilt Development

Effective gilt management programs that will meet replacement targets from a smaller pool of gilts with improved lifetime breeding performance (select gilts) are urgently needed. By making gilt management more efficient, we improve both the utilization of space and labor, and actually achieve a flow of eligible (service-ready) gilts within the design specifications of the gilt facility. This will ultimately reduce annual replacement rates (target for top 30% of breeding herds should be <50%), improve sow “fitness”, decrease sow death losses, and increase labor efficiency and space utilization.
Impact of Low Tidal Volumes During One-Lung Ventilation. A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES The link between ventilation strategies and perioperative outcomes remains one of the fundamental paradigms of thoracic anaesthesia. During one-lung ventilation (OLV), one lung is excluded from gas exchange and ventilation is directed at the dependent lung. The authors hypothesised that the use of low tidal volumes (VT) during OLV provides adequate gas exchange and improves postoperative outcome. DESIGN Meta-analysis of randomized clinical trials. SETTING Thoracic surgery. PARTICIPANTS Patients undergoing OLV. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The authors performed a meta-analysis of all randomized trials on low versus high VT during OLV in patients undergoing thoracic surgery. Outcomes of the study were gas exchange and airway pressures during and after OLV, postoperative pulmonary complications (PPCs), and hospital stay (HLOS). Fourteen randomized trials were selected, but only a few of them contained one outcome of interest. Low VT was associated with lower arterial oxygen tension, lower airway pressures, and higher arterial carbon dioxide tension at specific time points during OLV. Low VT was associated with preserved gas exchange after OLV, lower incidence of pulmonary infiltrations, and acute respiratory distress syndrome. Incidences of PPCs and HLOS were similar. CONCLUSIONS The use of low VT reduces airway pressure but worsens gas exchange during OLV. Preservation of postoperative oxygenation and reduction in infiltrates suggest a lung-protective modality with no demonstrable impact on PPCs and HLOS.
Cardiac ion channels.

The movement of ions across cardiac cell membranes generates the electrical potentials that activate the heart. Today's molecular biology is providing breathtaking new insights into the regulation of this electrical activity, which is the basis of electrocardiography. Whereas only a few years ago depolarization and repolarization of heart cells were attributed to changing membrane resistance, cardiac action potentials are now understood in terms of structural changes in the proteins that control ion fluxes across the plasma membrane. Ions cross hydrophobic lipid membranes by passing through regulated pores formed by members of an extended family of ion-channel proteins. The opening and .
Kidney ADP-Ribosyl Cyclase Inhibitors as a Therapeutic Tool for Diabetic Nephropathy

ADP-ribosyl cyclases (ADPR-cyclases)/CD38 have emerged as effecter molecules for generating novel Ca2+ signaling messengers, cyclic ADP-ribose (cADPR) and nicotinic acid adenine dinucleotide phosphate (NAADP) (1, 2) (see Figure 1). Mounting evidence has indicated that G protein-coupled receptors, including the angiotensin II (Ang II) receptor, mediate activation of ADPR-cyclase to generate Ca2+ signaling messengers (3-5). We have studied Ang II receptor-mediated activation of ADPR-cyclase, resulting in Ca2+ dysfunction
The Type Concept in Office Document Retrieval

The problem of the retrieval by content of office documents is addressed here. However, the retrieval by content is greatly enhanced if the semantic role of document objects can he described. For this reason we introduce a conceptual level of modeling resulting in the definition of conceptual structures of documents. Type definition is essential for the retrieval, but since office document structures tend to greatly differ from instance to instance, we introduce the concept of weak type, allowing the definition of types at different levels of detail (type hierarchies). In this paper a modeling approach based on these ideas is presented. Particular emphasis is put on the type definition and the use of types in query formulation and processing.
Job task and psychosocial risk factors for work-related musculoskeletal disorders among newspaper employees.

OBJECTIVES A cross-sectional study was conducted to assess the association of upper extremity musculoskeletal disorders and work-related factors among employees using video display terminals at a large metropolitan newspaper. METHODS The study included 1050 randomly selected workers from four departments. The workers were asked to complete questionnaires on symptoms, job tasks, and psychosocial and work organization conditions. Musculoskeletal disorders of the upper extremities were defined by frequency, duration, and intensity of symptoms not attributable to acute injury. Data were analyzed with the use of logistic regression. RESULTS A total of 973 workers completed the survey. The one-year period prevalence rate for any musculoskeletal disorder of the upper extremities was 41%. Neck symptoms (26%) were the most frequently reported, followed by hand or wrist (22%), shoulder (17%), and elbow (10%) symptoms. Greater time working at the video display station was associated with increased hand or wrist symptoms in a dose-response relationship. In addition, variables corresponding to increased work-load demands (eg, increased time working under deadline and increased job pressure) were associated with increased neck, shoulder, and hand or wrist disorders. Women were more likely to report symptoms in several areas, but this finding may reflect the concentration of women in jobs involving more risk factors. CONCLUSIONS The results suggest a high prevalence of musculoskeletal disorders of the upper extremities among newspaper employees, and they provide additional evidence that increased work load, time pressure, and greater hours of computer use are related to the occurrence of work-related musculoskeletal disorders among these workers, particularly for disorders in the hand or wrist area.
