A regional study of quality management infrastructure practices in USA and Mexico

Abstract: Presents the results of a study on quality management infrastructure practices and quality performance in manufacturing companies located in the North and Central regions of Mexico and the US Midwest region. Seven quality management infrastructure practices – top management support, strategic quality planning, quality information availability, employee training, supplier quality, customer focus, and quality citizenship – were assessed and compared. The research covered 372 manufacturing companies in both countries. Our findings show significant differences between the three regions. Companies located in the North region of Mexico exhibit significantly better levels of quality management infrastructure practices than companies located in the US Midwest and Central Mexico regions. Implications for decision‐makers for location, outsourcing, and joint ventures are discussed.

A prospective latent analyses study of psychiatric comorbidity of DSM-IV bipolar I and II disorders.

Abstract: Mantere O, Isometsa E, Ketokivi M, Kiviruusu O, Suominen K, Valtonen HM, Arvilommi P, Leppamaki S. A prospective latent analyses study of psychiatric comorbidity of DSM-IV bipolar I and II disorders. Bipolar Disord 2010: 12: 271–284. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective: To test two hypotheses of psychiatric comorbidity in bipolar disorder (BD): (i) comorbid disorders are independent of BD course, or (ii) comorbid disorders associate with mood. Methods: In the Jorvi Bipolar Study (JoBS), 191 secondary-care outpatients and inpatients with DSM-IV bipolar I disorder (BD-I) or bipolar II disorder (BD-II) were evaluated with the Structured Clinical Interview for DSM-IV Disorders, with psychotic screen, plus symptom scales, at intake and at 6 and 18 months. Three evaluations of comorbidity were available for 144 subjects (65 BD-I, 79 BD-II; 76.6% of 188 living patients). Structural equation modeling (SEM) was used to examine correlations between mood symptoms and comorbidity. A latent change model (LCM) was used to examine intraindividual changes across time in depressive and anxiety symptoms. Current mood was modeled in terms of current illness phase, Beck Depression Inventory (BDI), Young Mania Rating Scale, and Hamilton Depression Rating Scale; comorbidity in terms of categorical DSM-IV anxiety disorder diagnosis, Beck Anxiety Inventory (BAI) score, and DSM-IV-based scales of substance use and eating disorders. Results: In the SEM, depression and anxiety exhibited strong cross-sectional and autoregressive correlation; high levels of depression were associated with high concurrent anxiety, both persisting over time. Substance use disorders covaried with manic symptoms (r = 0.16–0.20, p < 0.05), and eating disorders with depressive symptoms (r = 0.15–0.32, p < 0.05). In the LCM, longitudinal intraindividual improvements in BDI were associated with similar BAI improvement (r = 0.42, p < 0.001). Conclusions: Depression and anxiety covary strongly cross-sectionally and longitudinally in BD. Substance use disorders are moderately associated with manic symptoms, and eating disorders with depressive mood.

Learning by Hiring: The Effects of Scientists’ Inbound Mobility on Research Performance in Academia

Abstract: This study investigates the effects of scientists’ inbound mobility on the research performance of incumbent scientists in an academic setting. The theoretical framework integrates insights from learning theory and social comparison theory to suggest two main mechanisms behind these effects: localized learning and social comparison. The authors propose several hypotheses about the conditions that might intensify or weaken such effects. Specifically, the arrival of new scientific personnel is likely to exert stronger positive effects on the performance of incumbent scientists with shorter (cf. longer) organizational tenure; in addition, academic departments with less diversified expertise and with higher levels of internal collaborations likely reap greater benefits from learning by hiring. The empirical findings, based on a longitudinal analysis of a sample of 94 U.S. academic chemical engineering departments, provide empirical support for these contentions.

Taxes, Theft, and Firm Performance

Abstract: This paper examines the interaction between income diversion and firm performance. Using unique Russian banking transaction data, I identify 42,483 spacemen, fly-by-night firms created specifically for income diversion. Next, I build a direct measure of income diversion for 45,429 companies and show that it is negatively related to firm performance. Then, I identify the main reason for the observed effect as managerial diversion rather than tax evasion per se. Finally, I show that stricter tax enforcement can improve firm performance. A one standard deviation increase in tax enforcement corresponds to an increase in the annual revenue growth rate by 2.6%.
