Online Identification of the Mutual Inductance for Vector-Controlled Induction Motor Drives

Mutual inductance of an induction machine may vary considerably when the flux reference varies. An important and frequent application of a variable flux reference is the operation in the field-weakening region. Standard assumption of constant mutual inductance is no longer valid and it becomes necessary to compensate for the mutual inductance variation. This paper proposes a novel method for on-line mutual inductance identification in vector-controlled induction machines. The method is characterized with a very simple structure, ease of implementation, very low parameter sensitivity, and the capability to provide an accurate estimate under both transient and steady-state operating conditions. Full experimental verification of the proposed scheme is provided and a number of potential applications in a vector-controlled induction motor drive are discussed.
Antidromically identified striatonigral projection neurons in the chronically implanted behaving rat: relations of cell firing to amphetamine-induced behaviors.

The effects of systematically administered amphetamine (0.25-5.0 mg/kg, sc) on neostriatal neurons recorded in chronically implanted behaving rats were studied. Projection neurons, identified by antidromic activation from the substantia nigra, fired very infrequently during most predrug behaviors (e.g., median rate, 0.02 spikes per second during locomotion; 17 of 18 fired less than 1 spike per second during all rated behaviors). Nonantidromic cells also tended to fire slowly (median rate, 0.02 spikes per second during locomotion; 20 of 24 cells fired less than 1 spike per second). Cells of both type showed up to 10-fold variations in firing rate across behaviors. For most neurons, amphetamine caused a reduction in the firing rate during related pre- and postdrug behaviors. For instance, the firing rate of 28 of 42 neurons was reduced during the initial amphetamine-induced locomotion as compared with the rate during predrug locomotion. Moreover, with the higher doses of amphetamine, there was a further reduction in firing rate corresponding to the transition from locomotion to stereotypies. In contrast to previous studies, which suggest that amphetamine generally increases neostriatal firing rate in behaving animals, these results suggest that amphetamine inhibits the numerous slowly firing neostriatal neurons, many of which were identified as projection neurons. Thus amphetamine alters the magnitude and pattern of neostriatal control of its neural targets.
Alignment between Competitive Strategies and Cost Management: a Study of Small Manufacturing Companies

This article analyzes the alignment between competitive strategies and management of manufacturing costs in small industrial firms for the purpose of obtaining competitive advantages, by means of a descriptive survey with quantitative approach in which the universe was small industrial firms in the transformation segment located in the city of Mossoro, Rio Grande do Norte, Brazil. The main results obtained demonstrate that the integration of competitive strategies with cost management results in advantages, principally for small industrial firms that adopt a stuck-in-the-middle posture with combined priorities for strategic actions by product differentiation and reduction of costs, and that alignment of competitive strategies with cost management is more favorable to small industrial firms that strive for product differentiation and cost leadership simultaneously, or exceptionally focus on differentiation. The results also indicate that competitive advantages emerge both from differentiation and low cost.
Explaining undergraduates' behavior intention of e-textbook adoption: Empirical assessment of five theoretical models

Purpose – The current study aims to investigate college students' behavioral intentions to adopt e-textbooks for their studies according to well-known theoretical intention-based models. Design/methodology/approach – This paper empirically assesses five theoretical models of technology acceptance, including the theory of planned behavior (TPB), the technology acceptance model (TAM), the decomposed TPB model (DTPB), the combined model of TAM and TPB (C-TAM-TPB), and the unified theory of acceptance and use of technology (UTAUT). The survey methodology and structural equation modeling (SEM) were employed to examine and compare these five models. Moreover, explanatory power, goodness-of-fit indices, and model parsimony were taken into consideration in the model comparisons. Findings – Both TPB and TAM provided less effective but adequate predictive behavioral power. However, TPB appeared to be more parsimonious than TAM and the other models. By focusing on specific beliefs of attitude, social and control inf.
Generic security cases for information system security in healthcare systems

Numerous data breach incidents have been reported in recent years and there is a continuing requirement to protect patient and clinician confidentiality. However, the diversity of security products, tools and techniques in the market place make it very hard for management to ensure that they have implemented coherent countermeasures to meet organisations higher-level objectives. This paper focuses on the problems that arise in implementing and maintaining cyber-security policies in large, complex healthcare organisations. We address these problems by the use of graphical argumentation techniques. In particular, we show how the Goal Structuring Notations (GSN) can be extended from applications in safetycritical systems. Security arguments presented with GSN can help managers to reason about cyber-security policies and procedures by bringing together claims and the evidence that supports them in a structured and coherent way. A further objective of this paper is to show how GSN can be used to construct security arguments that are informed by the analysis of previous security incidents in healthcare organisations. In particular, we present two generic security cases that embody the recommendations from incidents involving the United States' Veterans' Affairs (VA) administration and Shenzhen Hospital in China. These case studies were deliberately chosen to show how lessons learned in one country might inform security management in other healthcare systems. We also show that security cases can be created at a level of abstraction that support reuses and at the same time capture detailed recommendations from security incidents. (6 pages)
Enterprise Risk Management: Strategic Antecedents, Risk Integration and Performance

The current literature on the adoption of enterprise risk management (ERM) abstracts from the issue of its strategic context. Accounting for the interplay between ERM and various individual risk management (IRM) practices, this paper presents a theoretical basis to study the strategic determinants, risk integration, and value creation of ERM. We tested hypotheses with data from the US property and casualty (PC) insurance industry. Our results show that insurers with more reinsurance purchase and greater geographic diversification are more likely to adopt ERM. After ERM initiation, the magnitude of certain IRM adjustments is substantial. Interestingly, the market responds negatively to ERM adoption. ERM displays a strong negative correlation with firm value with a discount of 5% (4%) in terms of Tobin's Q (ROA).
Clinical significance of combined detection of serum tumor markers in diagnosis of patients with ovarian cancer.

OBJECTIVE To explore the predictive value of tumor markers, including cancer antigen 72-4 (CA72-4), cancer antigen 15-3 (CA15-3) and cancer antigen 125 (CA125), in single or combined detection, for the diagnosis of ovarian cancer. METHODS 120 patients diagnosed with ovarian cancer from August 2011 to March 2013 and 80 patients diagnosed with benign ovarian tumors were enrolled in this test, along with 50 health examination women randomly selected from the database as controls. Serum levels of CA72-4, CA15-3 and CA125 in this study were determined by electrochemiluminescence (ECL). RESULTS Serum levels of CA72-4, CA15-3 and CA125 in ovarian cancer were higher than those in healthy group and benign group (P<0.01). The sensitivity of combined detection of those three tumor markers for diagnosis of ovarian cancer was obviously higher than with single detection with each marker (P<0.01). CONCLUSIONS CA72-4, CA15-3 and CA125 could be a good combination in the diagnosis of ovarian cancer. Patients whose tumor markers continue to increase should be highly suspected of malignancy.
The Impact of Switching Costs Upon the Service Quality–Perceived Value–Customer Satisfaction–Service Loyalty Chain: A Study in the Context of Cellular Services in India

It is a common wisdom in the cellular service industry that high switching costs increase customer loyalty to a service provider and vice versa. Academic studies, too, have shown this to be true. However, a comprehensive understanding of the direct and indirect interactions of the nomologically proximate concepts of switching costs, service quality, perceived value, customer satisfaction, and customer loyalty has not yet been accomplished; in the present study, we attempt to do the same. In particular, the interaction effects of switching costs upon the service quality-perceived value link and the satisfaction-loyalty link are explored, and in both cases the effects are shown to be significant. To test these relationships, an empirical study among the mobile phone service users in India was carried out. Implications of the study for marketing theory and practice are discussed.
Relationship of physiological strain to change in heart rate during work in the heat.

Data collected from experiments involving (1) intermittent cycling and load carrying in dry, neutral to hot, ambient temperatures and (2) prolonged walking (3 to 3.5 mph) in hot, humid environments were used for correlation analysis between some measured physiological variables. Increasing the air temperature (Ta) resulted in (1) a shift of regression line of heart rate (HR) on oxygen uptake (Vo2) such that, for a given Vo2, HR was 10 beats/min higher for a rise of 10 °C in Ta, and (2) apparent slope for the linear regression of the HR during the last minute of work on the HR during the first minute of recovery becoming less steep with rise in Ta. For prolonged work loads requiring Vo2 of about 1 liter/min (representing about 30% of maximal Vo2) amd Vo2 of about 1.5 to 2.8 liters/min (representing 40 to 60% of maximal Vo2) the regression of rectal temperature on HR was 0.03 °C and 0.01 °C per beat per minute respectively. It was concluded that the rate of change rather than absolute values of these parame.
Attitude‐behaviour Inconsistency in Exporting

Focuses on the relationship between managerialattitudes towards exporting and exporting behaviour. A basic premiss is that the widely held assumption of a positive relationship between managerial attitudes and behaviour in exporting does not hold true in all circumstances, implying that in some cases a negative or no relationship between attitude and behaviour in exporting can be expected. Survey responses from a sample of manufacturing firms in Illinois support the basic premiss herein. Furthermore, the magnitude of attitude‐behaviour discrepancy among industrial firms was estimated to be sizeable among non‐exporting firms. Concludes with research, managerial, and policy implications of these findings.
The Effects of Unilateral Gastrocsoleus Recession

Background: Gastrocsoleus recession is commonly performed to correct equinus contracture of the ankle that may accompany foot and ankle disease in adults. There is concern that mechanical lengthening of the myotendinous unit causes permanent weakness and disability. This retrospective study reviewed the short-term and long-term objective and subjective results of patients who have had this procedure to determine if it is an appropriate adjunct to corrective foot surgery. Methods: Forty patients who had unilateral gastrocsoleus recession either as an isolated procedure or in conjunction with other surgeries were available for evaluation at an average 25.3 (range 6 to 50) months. Followup evaluation included the AOFAS ankle hindfoot score, subjective questionnaire, and physical examination. Preoperative and postoperative ranges of motion were compared. Mechanical strength testing was done using the contralateral extremity as a control. Maximal strength was measured by peak torque using a Cybex device (CYBEX International, Inc., Ronkonkoma, New York). Fatigue resistance was measured by comparing the maximal number of toe raises between the operative and nonoperative sides. Results: Range of motion improved from −3.5 to 15.3 degrees average dorsiflexion. Subjectively, two patients reported pain at the operative site, and one patient reported moderate weakness. The AOFAS score improved from 62.3 to 79.5. Strength testing of plantarflexion peak torque found the operative extremity to be 74% of the contralateral leg at followup. Peak torque improved from an average of 62.6% at 6 to 18 months to 82.2% after 18 months compared to the contralateral extremity. Fatigue resistance improved from 37.6% to 50.3% at 18 months. Two patients reported paresthesias in the sural nerve distribution. Conclusion: Gastrocsoleus recession is an effective procedure to correct equinus contracture either as an isolated procedure or as an adjunct to other foot surgery. While both fatigue resistance and strength decreased initially, both demonstrated improvement over time. Four patients had subjective complaints after the procedure.
Neighborhoods and Adolescent Development

Abstract:Researchers are increasingly interested in identifying specific aspects of adolescents' lives that are positively or adversely affected by their place of residence. This body of work suggests that it is important to consider neighborhoods when examining their 1) engagement in risk-related behaviors; 2) educational outcomes; 3) physical and mental health; and 4) their integration within social institutions. To date, however, no existing work has simultaneously considered the range of outcomes in which neighborhoods are believed to be important within and across these four domains. Using data from the National Longitudinal Study of Adolescent Health, we examine the extent to which neighborhoods influence adolescent outcomes across 34 characteristics nested within these four areas. The findings suggest that for adolescents, residential area is equally important in terms of risk behaviors, educational outcomes, and their integration within their families, schools, and churches. However, we find no evidence that neighborhoods are associated with adolescents' physical health or emotional well-being.
The Relationship Between the Ownership Structure and Board Effectiveness

The paper develops a theoretical model to better understand how the role (control versus direction) of the board of directors is influenced by the ownership structure and how that affects the board effectiveness. Most corporate governance research focuses on a universal link between corporate governance practices and performance outcomes, but neglects how the specific context of each company and diverse environments lead to variations in the effectiveness of different governance practices. This study suggests that the effectiveness of corporate governance practices must be seen in the light of contingencies related to the ownership structure of the firm. When ownership is diffuse, the control role of the board is going to be more important because it is difficult for the dispersed shareholders to co-ordinate their monitoring activities (Davies, 2002; Aguilera, 2005). Firms with dispersed ownership may obtain higher board effectiveness if their board combines the following characteristics: a high proportion of outside board members, dual leadership, smaller board size, shorter board tenure and less directorships by its board members. Board in firms with concentrated ownership on the other hand could be more effective when the board combines the following characteristics: a balance of insiders and outsiders, single leadership structure, larger board size, longer board tenure and more directorships by its board members. In light of scandals and perceived advantages in reforming corporate governance systems, debates have emerged over the appropriateness of implementing corporate governance recommendations mainly based on an Anglo-Saxon context characterized by dispersed ownership where markets for corporate control, legal regulation, and contractual incentives are key governance mechanisms. This paper adds to the literature that argues in favor of the need to adapt corporate governance policies to the local contexts of firms.
Carbonic Anhydrase Activity During Embryonic Development

1. Tissue carbonic anhydrase is usually formed at an early stage in the embryonic development of the chick and mouse. The enzyme does not appear in the blood until a relatively late stage has been reached. 2. In the erythrocytes, it is probable that the enzyme is confined to those cells produced in bone marrow. 3. Evidence is presented to support the theory that towards the end of development, there is a replacement of red cells which contain an embryonic type of haemoglobin but no carbonic anhydrase, by corpuscles in which the enzyme is present together with the adult type of haemoglobin.
Corporate Governance Index for Listed Indian Companies

In this paper, we have developed a corporate governance index for 500 large listed Indian firms from 2008 to 2011. The index construction utilizes information on six important corporate governance mechanisms namely the board of directors, the audit committee, the board committees and disclosure practices. The creation of the index for four years helps us to examine the advancement of corporate governance in India. The period under consideration is marked with numerous corporate governance reforms. The study indicates an escalating trend in the level of Corporate Governance Index of Indian Companies. The study further looks at the relationship between the Corporate Governance Index and financial performance (accounting and market performance) of companies. This analysis confirms that Indian markets value companies that carry out governance reforms proactively. It also encourages regulators to initiate further reforms.
1 THE RISK OF KNOWLEDGE SPILLOVERS AND CORPORATE SOCIAL RESPONSIBILITY : EVIDENCE FROM THE INEVITABLE DISCLOSURE DOCTRINE

In this study, we theorize and empirically examine whether companies respond to the threat of knowledge spillovers by strategically increasing their engagement in corporate social responsibility (CSR). To obtain exogenous variation in the threat of knowledge spillovers, we exploit a natural experiment provided by the rejection of the inevitable disclosure doctrine (IDD) by several U.S. states between 1991 and 2013. Since the doctrine prevents employees with valuable know-how from working for a competitor in the immediate future, the doctrine’s rejection facilitates knowledge appropriation by rivals. Using a difference-indifferences methodology, we find that companies react to the increased threat of knowledge spillovers by increasing their CSR. We further provide evidence that the increase in CSR is stronger for companies i) located closer to innovation hubs as well as companies operating in industries that are ii) more R&D intensive, iii) more competitive, and iv) have more attractive investment opportunities. Overall, these results are consistent with the notion that CSR serves as a strategic tool to mitigate the risk of knowledge spillovers.
Sitting posture: analysis of lumbar stresses with upper limbs supported.

The analysis of lumbar stresses in the sitting posture is performed for situations in which upper limbs are fully or partially supported by a worktable. A method is presented for biomechanical evaluation of moments and compressive forces acting on the lumbar intervertebral disk, based on the use of a force platform, a TV camera and a integrated system for the elaboration of signals. The on-line pictures given by this equipment show the ground reaction vector superimposed on the subject's image and allows a detailed analysis of the intervertebral loads. The results obtained in the subjects under study (six males and five females) are analysed statistically and extrapolation on the basis of body weight is demonstrated to be possible in situations where the arm support forces are not known. The myoelectric activity of the erector spinae muscles was also assessed. The aim of the study was to furnish a tool that can be used in all occupational environments and that will allow evaluation of the lumbar stresses .
Driving Tests and Road Safety: the Case of Mexico City

The purpose of a driving test is to prevent unskilled people from using cars, which supposedly increases road safety. We find that the obligatory driving tests do not increase road safety. Our empirical analysis relies on the data from Mexico City where the obligatory driving test has been abolished in January 2004. Our theoretical analysis builds on the Reverse Peltzman Effect: drivers become more careful and exert more effort on the roads if they know that the driving environment becomes less safe, due to the presence of incompetent drivers.
Evidence, Interpretation, and Qualification From Multiple Reports of Long-Term Outcomes in the Multimodal Treatment Study of Children With ADHD (MTA)

Objective: To review and provide details about the primary and secondary findings from the Multimodal Treatment study of ADHD (MTA) published during the past decade as three sets of articles. Method: In the second of a two part article, we provide additional background and detail required by the complexity of the MTA to address confusion and controversy about the findings outlined in part I (the Executive Summary). Results: We present details about the gold standard used to produce scientific evidence, the randomized clinical trial (RCT), which we applied to evaluate the long-term effects of two well-established unimodal treatments, Medication Management (MedMGT) and behavior therapy (Beh), the multimodal combination (Comb), and treatment “as usual” in the community (CC). For each of the first three assessment points defined by RCT methods and included in intent-to-treat analyses, we discuss our definition of evidence from the MTA, interpretation of the serial presentations of findings at each assessment point with a different definition of long-term varying from weeks to years, and qualification of the interim conclusions about long-term effects of treatments for ADHD based on many exploratory analyses described in additional published articles. Conclusions: Using a question and answer format, we discuss the possible clinical relevance of the MTA and present some practical suggestions based on current knowledge and uncertainties facing families, clinicians, and investigators regarding the long-term use of stimulant medication and behavioral therapy in the treatment of children with ADHD.
