R&D Intensity and Economic Recession

The authors employ the upper echelons theory and contingency theory in understanding the moderating effect of the chief executive officer (CEO) characteristics on the relationship between recession and research and development (R&D) intensity. The authors selected 2004 (nonrecession) and 2008 (recession) years for the analysis. Evidence was found that during recession, indeed, organizations decreased their R&D spending. The findings supported that CEOs with a shorter career horizon decreased R&D spending more dramatically than CEOs with a longer career horizon during recession. No evidence was found for the moderating effects of CEO tenure and insider status.
Emotional Resilience Mediates the Relationship Between Mindfulness and Emotion

Previous studies have shown that mindfulness promotes positive mood states and reduces negative ones; however, the underlying mechanisms are still controversial. This study assessed the role of emotional resilience as a mediator between mindfulness and emotional regulation. A total of 421 college students (M age = 20.0 year, SD = 2.0; males/females/missing are 152/248/4) completed the Five-Facet Mindfulness Questionnaire, Profile of Mood States, and Adolescents’ Emotional Resilience Questionnaire (AERQ). The ability to generate positive emotion (GP) and the ability to recover from negative emotion (RN) are two subscales of the AERQ. A Structural Equation Modeling analysis indicated that emotional resilience mediated the connection between mindfulness and emotion. Specifically, GP mediated the relationship between mindfulness and both positive and negative emotions while RN mainly mediated the relationship between mindfulness and negative emotions. These findings suggest that mindfulness may play a role in regulating positive and negative emotions through the two different aspects of emotional resilience.
The International Debt Crisis, Investor Contagion, and Bank Security Returns in 1987: The Brazilian Experience

The authors use event-study methods to examine security returns for the twenty-five largest U.S. bank holding companies surrounding two events: (1) Citicorp's $3 billion loan-loss-reserve decision of May 19, 1987 and (2) subsequent follow-the-leader behavior by other major banking companies. Although the market anticipated rational follow-the-leader behavior and rewarded it, the events were only partially anticipated. The authors interpret the loan-loss-reserve decisions as foreshadowing the write-down of LDC loans. Such bookkeeping entries affect market prices because they signal economic value-enhancing corporate and strategic restructurings. Copyright 1990 by Ohio State University Press.
IMPACT OF GOVERNMENT SECTORIAL EXPENDITURE ON THE ECONOMIC GROWTH OF NIGERIA

Government expenditures remain the bedrock of Nigeria’s economic growth. Hence the need to critically evaluate the impact of expenditures’ some priority sectors on the economic growth. A Cochrane-Orcutt and ECM method was adopted to measure the long run effect of selected macroeconomic variables economic growth. The result shows that expenditure on telecommunication, Defence and security, Education and Health Sector have made positive impact on Nigeria’s economic growth. But transportation and agricultural expenditures have impacted negatively in the economic growth in Nigeria. The conclusion therefore is that the level of government expenditures for transportation and agricultural development is still not adequate to build the much need capacity in the sectors to impact positively to economic growth.
What Does the Volatility Risk Premium Say About Liquidity Provision and Demand for Hedging Tail Risk?

This article provides a data-driven analysis of the volatility risk premium, using tools from high-frequency finance and Big Data analytics. We argue that the volatility risk premium, loosely defined as the difference between realized and implied volatility, can best be understood when viewed as a systematically priced bias. We first use ultra-high-frequency transaction data on SPDRs and a novel approach for estimating integrated volatility on the frequency domain to compute realized volatility. From that we subtract the daily VIX, our measure of implied volatility, to construct a time series of the volatility risk premium. To identify the factors behind the volatility risk premium as a priced bias, we decompose it into magnitude and direction. We find compelling evidence that the magnitude of the deviation of the realized volatility from implied volatility represents supply and demand imbalances in the market for hedging tail risk. It is difficult to conclusively accept the hypothesis that the direction or sign of the volatility risk premium reflects expectations about future levels of volatility. However, evidence supports the hypothesis that the sign of the volatility risk premium is indicative of gains or losses on a delta-hedged portfolio.
Managing product variety in emerging markets

Purpose – The need for an efficient provision of product variety has been widely established as a means of competing in the marketplace, yet previous studies into the management of product variety have commonly analysed products in isolated developed markets. The purpose of this paper is to investigate how firms manage their product variety in emerging markets. This paper aims to investigate the rationale underlying the restriction of variety in such settings, and define general mechanisms by which firms can adapt their product variety when operating in both emerging and developed markets simultaneously.Design/methodology/approach – The paper uses the case of a global vehicle manufacturer that offers common products across developed and emerging markets to illustrate the difference between them in terms of product variety, and examine the process that underlies its management. The paper utilises a combination of data collection techniques.Findings – The paper shows empirically how product variety (in part.
Diva, a Bcl-2 Homologue that Binds Directly to Apaf-1 and Induces BH3-independent Cell Death*

We have identified and characterized Diva, which is a novel regulator of apoptosis. Sequence analysis revealed that Diva is a member of the Bcl-2 family of proteins containing Bcl-2 homology domain 1, 2, 3, and 4 (BH1, BH2, BH3, and BH4) regions and a carboxyl-terminal hydrophobic domain. The expression of Diva mRNA was detected in multiple embryonic tissues but was restricted to the ovary and testis in adult mice. The expression of Diva promoted the death of 293T, Ramsey, and T47D cells as well as that of primary sensory neurons, indicating that Diva is a proapoptotic protein. Significantly, Diva lacks critical residues in the conserved BH3 region that mediate the interaction between BH3-containing proapoptotic Bcl-2 homologues and their prosurvival binding partners. Consistent with this, Diva did not bind to cellular Bcl-2 family members including Bcl-2, Bcl-XL, Bcl-w, Mcl-1, and A1/Bfl-1. Furthermore, mutants of Diva lacking the BH3 region fully retained their proapoptotic activity, confirming that Diva promotes apoptosis in a BH3-independent manner. Significantly, Diva interacted with a viral Bcl-2 homologue (vBcl-2) encoded by the Kaposi’s sarcoma-associated herpesvirus. Consistent with these associations, apoptosis induced by Diva was inhibited by vBcl-2 but not by Bcl-XL. Importantly, Diva interacted with Apaf-1, an adapter molecule that activates caspase-9, a central death protease of the apoptotic pathway. The expression of Diva inhibited the binding of Bcl-XL to Apaf-1, as determined by immunoprecipitation assays. Thus, Diva represents a novel type of proapoptotic Bcl-2 homologue that promotes apoptosis independently of the BH3 region through direct binding to Apaf-1, thus preventing Bcl-XL from binding to the caspase-9 regulator Apaf-1.
Transcutaneous electric acupoint stimulation alleviates remifentanil-induced hyperalgesia in patients undergoing thyroidectomy: a randomized controlled trial.

BACKGROUND In this prospective, randomized, double-blind study, we verified the hypothesis that TEAS can alleviate remifentanil-induced hyperalgesia in patients undergoing thyroidectomy. METHODS 60 American Society of Anesthesiologists physical status (ASA) I-IIpatients, aged 18-60 year, scheduled for thyroidectomy were randomly allocated to TEAS or sham groups. TEAS consisted of 30 min of stimulation (6-9 mA, 2/10 Hz) on the Hegu (LI4) and Neiguan (PC6) before anesthesia. Anesthesia was maintained with sevoflurane adjusted to bispectral index (40-60) and target remifentanil 5.0 ng/ml. Mechanical pain thresholds were assessed using electronic von Frey. The primary outcome was mechanical pain thresholds. Secondary outcomes included postoperative pain scores, the time to first rescue analgesic, cumulative number of rescue analgesia, and side effects, including postoperative nausea and vomiting (PONV), dizziness and shivering in 24 h postoperatively. RESULTS Baseline mechanical pain thresholds were similar between the groups. The analysis revealed the decrease in mechanical threshold was greater in the sham group than the TEAS group (P < 0.001). Postoperative pain scores and cumulative number of rescue analgesia were lower in the TEAS group (P < 0.05). In addition, TEAS group patients reduced the incidence of PONV and shivering. CONCLUSION Preoperative TEAS can attenuate remifentanil-induced hyperalgesia in patients undergoing thyroidectomy.
Guanxi Networks and Creativity in Taiwanese Project Teams

Personal connections, also called guanxi in Chinese culture, are embedded within a network of interdependent social exchanges, providing access to resources, information and supports, therefore facilitating performance. Building guanxi networks means building social networks. Project teams are commonly used as fundamental units in organizations, partly in order to generate more creative ideas, and so this paper evaluates how project teams use their guanxi networks within and outside of their teams and across boundaries to stimulate their creative performance. Fifty-four product development project teams with 293 members from high-tech Taiwanese firms participated in this study. Findings suggested that, in a guanxi culture such as Taiwan's, in order to facilitate a project team's creative performance, the most important task is to develop a more cohesive social unit before the team extends its external networks, since Chinese culture regards people first as members of groups, and secondly as individuals.
Radiosurgery for parasagittal and parafalcine meningiomas.

OBJECT Parasagittal and parafalcine (PSPF) meningiomas represent the second most common location for intracranial meningiomas. Involvement of the superior sagittal sinus or deep draining veins may prevent gross-total resection of these tumors without significant morbidity. The authors review their results for treatment of PSPF meningiomas with radiosurgery. METHODS The authors retrospectively reviewed the institutional review board-approved University of Virginia Gamma Knife database and identified 65 patients with 90 WHO Grade I parasagittal (59%) and parafalcine (41%) meningiomas who had a mean MRI follow-up of 56.6 months. The patients' mean age was 57 years, the median preradiosurgery Karnofsky Performance Status score was 80, and the median initial tumor and treatment volumes were 3 and 3.7 cm(3), respectively. The median prescription dose was 15 Gy, isodose line was 40%, and the number of isocenters was 5. Kaplan-Meier analysis was used to determine progression-free survival (PFS). Univariate and multivariate Cox regression analyses were used to identify factors associated with PFS. RESULTS The median overall PFS was 75.6 months. The actuarial tumor control rate was 85% at 3 years and 70% at 5 years. Parasagittal location, no prior resection, and younger age were found to be independent predictors of tumor PFS. For the 49 patients with clinical follow-up (mean 70.8 months), the median postradiosurgery Karnofsky Performance Status score was 90. Symptomatic postradiosurgery peritumoral edema was observed in 4 patients (8.2%); this group comprised 3 patients (6.1%) with temporary and 1 patient (2%) with permanent clinical sequelae. Two patients (4.1%) died of tumor progression. CONCLUSIONS Radiosurgery offers a minimally invasive treatment option for PSPF meningiomas, with a good tumor control rate and an acceptable complication rate comparable to most surgical series.
Estimation of international construction performance: analysis at the country level

The measurement or estimation of the degree of internationalization of multinational corporations (MNCs) remains lacking although many studies have been completed on MNCs in the construction industry. Dunning's Eclectic Paradigm suggests that the determinants of internationalization depends on the ownership (O), locational (L) and internalization (I) advantages of a firm. Another important factor relates to the involvement of a firm among specialized fields in the construction industry, i.e. the specialty (S) advantages. This paper proposes the OLI+S model for measuring/estimating the internationalization process of construction MNCs, according to nationalities, using the following ratios: O‐IRTR, L‐IBD, I‐OMS and S‐ISF. Major players in the international construction market were analysed using these ratios. The OLI+S model shows that construction MNCs from different nationalities demonstrated different patterns in the internationalization process depending on their business strategies, indigenous market situations, historical factors, etc. among others.
JC virus genotyping offers a new paradigm in the study of human populations

A small DNA virus, named JC virus (JCV) and belonging to the Polyomaviridae, is attracting the attention of anthropologists worldwide, as JCV genotyping appears to be a novel means of elucidating human migrations and the origins of various ethnic groups. The basic properties of JCV, the regional distributions of JCV genotypes, and the phylogenetic relationships among various JCV genotypes are described. Then, a study is described in which the origin of the modern Japanese was extensively investigated using the JCV genotyping method. Based on JCV genotypes in neighboring areas, the origins of people who carried JCV genotypes to the Japanese Archipelago are discussed. Finally, the relationships between JCV genotypes and Y‐chromosome haplogroups are examined, as genetic variation on the Y chromosome has recently been examined in detail to investigate ancient human migrations and the population structures of human groups.

Importance of Public Service Reform: the Case of Kenya

International donors supporting Kenya's development strategies have increasingly tied aid to the implementation of policy and sectoral reforms. After being confronted by more than 150 required structural adjustment conditions, the Government's good rhetoric but slow response led frustrated donors in November 1991 to suspend all foreign-exchange relief, and large blocks of bilateral aid, pending substantial progress in meeting these requirements.
ABO Blood Group System and Gastric Cancer: A Case-Control Study and Meta-Analysis

This study focuses on the association between the ABO blood group system and the risk of gastric cancer or Helicobacter pylori infection. The data for the ABO blood group was collected from 1045 cases of gastric cancer, whereby the patient underwent a gastrectomy in Ruijin Hospital, Shanghai. The information on the ABO blood group from 53,026 healthy blood donors was enrolled as control. We searched the Pubmed database on the relationship between ABO blood groups and gastric cancer risk for meta-analysis. In our case-control study, the risk of gastric cancer in blood group A was significantly higher than that in non-A groups (O, B and AB) (odd ratio, OR1.34; 95% confidential interval, CI 1.25–1.44). Compared with non-O groups (A, B and AB), individuals with blood group O demonstrated a reduced risk of gastric cancer (OR = 0.80; 95% CI 0.72–0.88). The proportion of H. pylori infection in blood group A individuals was significantly higher than that in non-A blood groups (OR = 1.42; 95% CI 1.05–1.93). We further combined our data with the published data of others, and crossreferenced the risk of gastric cancer with the blood type, finding consistent evidence that gastric cancer risk in the blood A group was higher than that in the non-A groups (OR = 1.11; 95% CI 1.07–1.15), and that blood type O individuals were consistently shown gastric cancer risk reduction (OR = 0.91; 95% CI 0.89–0.94). Our study concluded that there was a slightly increased risk of gastric cancer in blood group A individuals, and people with blood type A are more prone to be infected by H. pylori than other ABO blood type individuals, whereas, a slightly decreased risk of gastric cancer was identified in blood type O individuals.
Government Debt, Agent Heterogeneity and Wealth Displacement in a Small Open Economy

The consequences of government debt on capital formation, financial wealth and labor are investigated in a small open economy with demographic heterogeneity. Two alternative types of demographics are considered: one with intragenerational heterogeneity of the "savers-spenders" (SS) type, and one with intergenerational heterogeneity of the OLG type. The effects of debt and the financial crowding out morphology strictly depend on the type of demographic heterogeneity. While in the SS economy debt crowds out capital, increases net foreign assets and contracts labor, in the OLG economy it generates the exact opposite results. Our results differ substantially from those observed in a closed economy, where the type of demographic heterogeneity plays no qualitative role for the effects of debt on wealth and factor employment.
Personnel Strategy In Eleven Japanese Manufacturing Companies In The Uk

For some years now the contemporary management literature has been burgeoning with articles on Japanese management practice. There is debate as to how representative of reality some of these accounts actually are, which practices are crucial to business success and whether their transfer to a Western context is possible or desirable. These concerns are by no means limited to academic circles; many prominent Western companies with manufacturing operations in the UK are experimenting with elements of “Japanese” management practice, particularly within the motor industry.
Phytophthora ipomoeae sp. nov., a new homothallic species causing leaf blight on Ipomoea longipedunculata in the Toluca Valley of central Mexico

A Phytophthora species was found on blighted foliage of Ipomoea longipedunculata, a morning glory native to the highlands of central Mexico. Based on host range, morphology, allozymes, mitochondrial DNA haplotype and rDNA sequences it is concluded that a new Phytophthora species, P. ipomoeae sp. nov., is the causal agent of leaf blight disease on I. longipedunculata.
Investigation of magnet arrangements in double layer interior permanent-magnet motors

In this paper, we investigate the best magnet arrangement and appropriate circuit parameters in double layer interior permanent-magnet motors for high speed applications using flux-weakening control. First, the characteristics of the several motors with the double layer magnet arrangements are compared by the finite element method, for example, straight type, V type, and their combination. Next, the appropriate magnet arrangement and the circuit parameters of the motors are discussed from the viewpoints of wide operating range and high efficiency. Finally, the characteristics of the proposed motor are verified by the measurement. It is clarified that the motor with the triangle magnet arrangement, which is the combination of the straight and V type, is suitable for high speed and high power applications.
A study of operations management constructs and their relationships

This paper describes an exploratory research effort to analyze and classify emerging operations management practices in US manufacturing. Using a survey of senior materials and operations management professionals in the United States, this study investigates manufacturers' supplier assessment practices, new product design and development practices, just‐in‐time practices, and quality practices. This study also identifies practices that share common variance‐covariance characteristics and to what extent the observed practices are linked to their underlying factors by means of exploratory factor analysis. Finally, bivariate correlation analysis is used to examine the relationships of the factors.
Variations in the Financial Reporting Environment and Earnings Forecasting

This paper examines variations in the financial reporting environment internationally. In particular, I investigate the relation between variations in accounting-related institutional factors (choice, accrual accounting and enforcement) and the accuracy of analysts' earnings forecasts. Controlling for firm- and country-level factors, I document that the extent of choice among accounting methods is associated with lower forecast accuracy. This finding is consistent with analysts' performance suffering from the increased task complexity (and/or managers using flexibility for purposes other than to provide information). The degree of prescribed accrual accounting is positively correlated with forecast accuracy, consistent with both accruals providing useful information and with the smoothing function of accruals. Enforcement of accounting standards is positively related with forecast accuracy, suggesting that enforcement encourages managers to follow prescribed rules, which, in turn, reduces analysts' uncertainty. Finally, I examine whether the roles of accrual accounting and choice vary with the level of enforcement. Although univariate tests support these interaction hypotheses, multivariate tests do not.
Between degradation and gentrification in a post-transformational metropolis city center: the case of St. Petersburg

Two dimensions of post-socialist urban transformation – socio-spatial restructuring and changes in urban morphology – are still present in the urban cores of such cities as St. Petersburg. The process of transformation has produced certain peculiarities concerning general modernization trends. Unlike in the majority of cities, the historic center of a post-transformation metropolis has witnessed the simultaneous struggle of two trends: residential gentrification and social degradation. None of the processes became dominant over the studied period; nor was a balance reached between the two trends. Fundamentally, different types of spatial behavior among social groups prevailed in the center. It is likely that this social contrast affected the closing of space within and around the buildings especially among those with higher income status who lived in these buildings. This example shows that the two dimensions of ongoing post-socialist urban transformation mentioned above are closely interrelated – social shifts are actively changing physical urban landscape.
