Guest Editors’ Introduction: The Role of Human Resources and Organizational Factors in Ambidexterity

Ambidexterity is a growing field of management research. However, the role of human resources (HR) and organizational factors needs further exploration because of the fragmented nature of prior work and the subsequent lack of a unifying framework. Our review of 41 empirical studies identifies distinct research streams that relate to the effects of employee characteristics, leader characteristics, organizational structure, culture, social relationships, and organizational environment on ambidexterity. We discuss the most important findings within each stream, which contributes to the HR and ambidexterity literature by addressing the current state of our knowledge. To move forward research in this area, we identify important, yet underexplored areas in each stream. This contributes to the literature by highlighting specific gaps in our current knowledge that represent new avenues for future research. We also identify important interrelationships between different streams that need further clarification. We summarize our findings into an integrative model that elucidates the role of HR and organizational factors in ambidexterity. This contributes to a more comprehensive understanding of ambidexterity from the HR and organizational perspectives. © 2015 Wiley Periodicals, Inc.
Factors Influencing Quality of Life in Elderly Patients Undergoing Total Knee Replacement Surgery

Summary: Total knee arthroplasty is one of the most common treatment for patients with severe knee osteoarthritis. Therefore, it is important to understand factors predicting patients’ quality of life during post operation. Content Outline: Total knee arthroplasty is one of the most common treatment for elderly patients with severe knee osteoarthritis. During post operation, it is important to assess patients’ quality of life. The aim of this study was to examine pain intensity, physical activities, depression in predicting elderly patients undergoing total knee arthroplasty at 6 week quality of life. The samples in this study were hundred of elderly patients undergoing total knee arthroplasty at one tertiary care hospital in Bangkok, Thailand. The questionnaires included demographic questionnaire, Numeric Rating Scale, Modified Barthel Activities of Daily Index, Thai Geriatric Depression Scale-15, and the Osteoarthritis of Knee Hip Quality of life questionnaire. Data were analyzed using descriptive statistics, Pearson’s correlation coefficients, and multiple linear regression. The results indicated that pain intensity level had a strong negative correlation with quality of life whereas physical activities had a moderate positive correlation with quality of life. All predictors could explain 46% of variance on patients’ quality of life. The results suggested that it is necessary to have an intervention program to assess and mage pain after discharge as well as promoting physical activities for this population. This will then lead to enhancement of patients’ quality of life.

A structural event study for M&As: an application in corporate governance

ABSTRACT We apply structural event study methodology in the context of corporate governance to account for the interaction of two merger and acquisition (M&A) effects: synergy (total value) and dominance (bargaining power). The interaction of these effects simultaneously determines the parties’ abnormal returns. We posit that M&A synergy effects correspond to changes in agency costs between target’s management and target’s shareholders, while the dominance effects correspond to the balance of power between acquirer and target during negotiations. Our structural estimates suggest that more stable or entrenched directors generate higher value during normal operations but are softer negotiators when their firm becomes an acquisition target.
Synergic Individual Entrepreneurial Orientation of University Students

While innovation is the sharp implement of entrepreneurs, knowledge is the critical element of the innovation system. The collaboration and synergy between the participants of these innovation systems are vital as they become a “laboratory for knowledge based economic development. ” On the other side, entrepreneurship has been widely recognized as the engine of job creation and economic prosperity. Albania as a developing country facing high unemployment rates promotes among young adults the continuous development of entrepreneurial activities, which can partially provide a solution to the increasing unemployment. The purpose of this research is to assess a new measurement model of specific entrepreneurial orientation which would contribute to increasing the university students` intention of becoming entrepreneurs. The study demonstrated that increasing the collaboration of students with industry and governmental institutions in supporting their innovative ideas will increase their intention towards entrepreneurship.
The Influence of the Route of Antibiotic Administration, Methicillin Susceptibility, Vancomycin Duration and Serum Trough Concentration on Outcomes of Pediatric Staphylococcus aureus Bacteremic Osteoarticular Infection

Background: Bacteremia is often one factor used in deciding the need for prolonged intravenous antimicrobial therapy in osteoarticular infections (OAIs). We examined treatment practices and outcomes of Staphylococcus aureus bacteremic osteoarticular infections (BOAIs) evaluated at Texas Children’s Hospital. Methods: Cases of acute hematogenous OAI in children with positive blood cultures for S. aureus at Texas Children’s Hospital between 2011 and 2014 were reviewed. Orthopedic complications included chronic osteomyelitis, growth arrest, pathologic fracture, avascular necrosis and chronic dislocation. Acute kidney injury was defined as a doubling of the baseline creatinine. Results: One hundred and ninety-two cases of S. aureus OAI were identified with 102 cases of BOAI included [35 methicillin-resistant S. aureus (MRSA)]. Twenty-five patients were discharged home on oral antibiotics. Patients discharged on oral antibiotics had a shorter duration of fever, had a more rapid decline in C-reactive protein and were less likely to have MRSA. The frequency of orthopedic complications did not increase in patients who received early transition to oral antibiotics. For patients with MRSA bacteremia, the rates of complications between those who received ≥7 days versus <7 days of vancomycin did not differ. Vancomycin serum troughs >15 µg/mL were not associated with a decreased duration of fever, bacteremia or hospitalization, need for repeat operation or orthopedic complications but were associated with acute kidney injury. Conclusions: S. aureus BOAIs are associated with substantial morbidity. Early transition to oral therapy may be a safe option for select patients with S. aureus BOAI, including those due to MRSA. Prolonged courses of vancomycin and vancomycin troughs >15 &mgr;g/mL were not associated with improved outcomes for MRSA OAI.
Mark-to-Market Accounting: Guilty or Not?

As the recent credit crisis unfolded, fair value accounting provoked a fierce debate among politics, academics, and bankers. Even though many believe that fair value accounting exacerbated the crisis, some commentators argue that fair value accounting was the prime reason for the financial meltdown. Proponents, on the other hand, believe fair value accounting prevented more calamitous consequences of the credit crisis by acting as an early warning system. This article traces the role of fair value accounting during the crisis in light of these arguments. In this context, the article focuses on two key arguments so as to find out whether fair value worsened the crisis. The first argument is that fair value accounting played a significant role in actual or potential bank failures. With respect to bank failures, we found that fair value accounting did not play a significant role during the crisis. The problem for many broker-dealers and banks was short-term funding difficulty after the interbank markets dried up. For some others, credit losses rather than fair value losses played a key role in bank failures. The second argument in the context of the crisis was the alleged procyclical effects of fair value accounting. Given its hybrid features and the extent to which it impacted upon balance sheets as revealed by empirical data, we conclude that fair value accounting in its current form did not cause pro-cyclical behavior and a downward spiral.
Febrile temperatures induce cytoadherence of ring-stage Plasmodium falciparum-infected erythrocytes

In falciparum malaria, the malaria parasite induces changes at the infected red blood cell surface that lead to adherence to vascular endothelium and other red blood cells. As a result, the more mature stages of Plasmodium falciparum are sequestered in the microvasculature and cause vital organ dysfunction, whereas the ring stages circulate in the blood stream. Malaria is characterized by fever. We have studied the effect of febrile temperatures on the cytoadherence in vitro of P. falciparum-infected erythrocytes. Freshly obtained ring-stage-infected red blood cells from 10 patients with acute falciparum malaria did not adhere to the principle vascular adherence receptors CD36 or intercellular adhesion molecule-1 (ICAM-1). However, after a brief period of heating to 40°C, all ring-infected red blood cells adhered to CD36, and some isolates adhered to ICAM-1, whereas controls incubated at 37°C did not. Heating to 40°C accelerated cytoadherence and doubled the maximum cytoadherence observed (P < 0.01). Erythrocytes infected by ring-stages of the ICAM-1 binding clone A4var also did not cytoadhere at 37°C, but after heating to febrile temperatures bound to both CD36 and ICAM-1. Adherence of red blood cells infected with trophozoites was also increased considerably by brief heating. The factor responsible for heat induced adherence was shown to be the parasite derived variant surface protein PfEMP-1. RNA analysis showed that levels of var mRNA did not differ between heated and unheated ring-stage parasites. Thus fever-induced adherence appeared to involve increased trafficking of PfEMP-1 to the erythrocyte membrane. Fever induced cytoadherence is likely to have important pathological consequences and may explain both clinical deterioration with fever in severe malaria and the effects of antipyretics on parasite clearance.
Face capture more attentional resource than No-face Object: An ERP study

This study want to find electrophysiological evidence to test whether face capture more attention than object, and whether the attention capture of face automatically or controllably. Fifteen subjects were tested on a three-stimulus visual oddball task, in which faces and objects as distractor stimuli were presented in different blocks separately. Face as task-irrelevant stimuli elicited earlier, greater and frontal-distributed P3a, which suggests that faces can faster capture more attention than object automatically. And we infer that face and object as distractor stimuli are processed in different brain mechanisms.
Food habits and energy and nutrient intake in Swedish adolescents approaching the year 2000

In 1993‐94 a nutritional survey of 15‐year‐old adolescents was carried out in Uppsala, a university city in eastern Sweden, and in Trollhättan, an industrial town in the western part of the country. The study was the beginning of a longitudinal nutritional survey of 193 boys and 218 girls randomly selected from the official population register. The dietary methods used were a food frequency questionnaire (FFQ) and a combined estimated and weighed 7‐day dietary record. According to the FFQ both boys and girls consumed cereals, butter or margarine and something from the group meat/fish/eggs every day. Milk, milk products, sweets and snacks were consumed more than once per day. Vegetables and fruit/ roots were consumed less often. There was relatively good correlation between the FFQ and the 7‐day record results.
Structure of the Circumnuclear Region of Seyfert 2 Galaxies Revealed by Rossi X-Ray Timing Explorer Hard X-Ray Observations of NGC 4945

NGC 4945 is one of the brightest Seyfert galaxies on the sky at 100 keV, but is completely absorbed below 10 keV; its absorption column is probably the largest that still allows a direct view of the nucleus at hard X-ray energies. Our observations of it with the Rossi X-Ray Timing Explorer (RXTE) satellite confirm the large absorption, which for a simple phenomenological fit using an absorber with solar abundances implies a column of × 1024 cm-2. Using a more realistic scenario (requiring Monte Carlo modeling of the scattering), we infer the optical depth to Thomson scattering of ~2.4. If such a scattering medium were to subtend a large solid angle from the nucleus, it should smear out any intrinsic hard X-ray variability on timescales shorter than the light-travel time through it. The rapid (with a timescale of ~1 day) hard X-ray variability of NGC 4945 discovered by us with RXTE implies that the bulk of the extreme absorption in this object does not originate in a parsec-size, geometrically thick molecular torus. Instead, the optically thick material on parsec scales must be rather geometrically thin, subtending a half-angle less than 10°, and it is likely to be the same disk of material that is responsible for the water maser emission observed in NGC 4945. Local number counts of Seyfert 1 and Seyfert 2 galaxies show a large population of heavily obscured active galactic nuclei (AGNs) which are proposed to make up the cosmic X-ray background (CXRB). However, for this to be the case, the absorption geometry in the context of axially symmetric unification schemes must have the obscuring material subtending a large scale height—contrary to our inferences about NGC 4945—implying that NGC 4945 is not a prototype of obscured AGNs postulated to make up the CXRB. The small solid angle of the absorber, together with the black hole mass (of ~1.4 × 106 M☉) from megamaser measurements, allows a robust determination of the nuclear luminosity, which in turn implies that the source radiates at ~10% of the Eddington limit.
Biodegradability Study by FTIR and DSC of Polymers Films Based on Polypropylene and Cassava Starch

The polypropylene resistance to biological attacks is related to the lack of functional groups recognizable by microbial enzymatic systems. The incorporation of compatibilizing agents in polypropylene (PP)/starch (S) blends favors the interactions of their components and can potentially induce the material degradation. In order to study the degradation of PP/S blends, films were prepared with a compatibilizing agent (AC), constituted by polypropylene grafted with acrylamide (PP-g-AAm). The films were placed in an Erlenmeyer flask containing 100 ml of a basal mineral medium with microorganisms inoculated in a cellulose filter, taken from an effluent. The FTIR analyzes of the films with the AC agent showed significant differences in the absorption bands, with respect to the control film. The asymmetric stretch signal of the grafted acrylamide that appeared at 3292 cm -1 increased in intensity only in the inoculated blends. In addition, hydrolysis was evidenced by the stretching signal of the OH bond. Abrupt changes were observed in the carbonyl region (1700-1600 cm -1 ) with the appearance of new bands, which shows the rupture of polymer chains. In the blends DSC analysis, a slight nucleation effect is observed in addition to a considerable increase in the degree of crystallinity, so it is suggested that the degradation could be occurring in the amorphous regions.

Hostility and the Metabolic Syndrome in Older Males: The Normative Aging Study

Objective: Several studies have shown that hostility, as measured by the Minnesota Multiphasic Personality Inventory–derived Cook-Medley Hostility Scale (Ho), is positively associated with several cardiovascular risk factors, possibly accounting for the relationship between Ho scores and cardiovascular mortality. This study was undertaken to examine associations between hostility and cardiovascular risk factors representing the metabolic syndrome in 1081 older men who participated in the Normative Aging Study. Methods: Subjects included men who completed the Minnesota Multiphasic Personality Inventory in 1986 and who participated in a subsequent laboratory examination within 1 to 4 years. Total and subscale Ho scores were computed, and associations with anthropometric data, cigarette smoking, dietary information, serum lipids, blood pressure, and fasting glucose and insulin levels were examined. Results: The total Ho score was positively associated with waist/hip ratio, body mass index, total caloric intake, fasting insulin level, and serum triglycerides. The Ho score was inversely related to education and high-density lipoprotein cholesterol concentration. Path analysis also suggested that the effects of hostility on insulin, triglycerides, and high-density lipoprotein cholesterol were mediated by its effects on body mass index and waist/hip ratio, which, in turn, exerted their effects on lipids and blood pressure through insulin. Conclusions: The results are consistent with those of prior research and also suggest that, in older men, hostility may be associated with a pattern of obesity, central adiposity, and insulin resistance, which can exert effects on blood pressure and serum lipids. Furthermore, effects of hostility on the metabolic syndrome appear to be mediated by body mass index and waist/hip ratio.
Mechanisms of Action of Anti–tumor Necrosis Factor &agr; Agents in Crohn’s Disease

Abstract:Crohn’s disease (CD) is characterized by inflammation that can affect any part of the gastrointestinal tract. It is a chronic destructive condition that follows a relapsing–remitting course and can lead to disability and a poor quality of life. Lifelong pharmacotherapy with systemic immunomodulator therapies remains the cornerstone of CD management. Advances in understanding of the immunopathogenic mechanisms underlying chronic gut inflammation in CD have led to the development of effective biological therapies for patients with CD. Tumor necrosis factor &agr; (TNF-&agr;) is a potent proinflammatory cytokine that plays a pivotal role in the development of Crohn’s inflammation. Therapies designed to target this cytokine have revolutionized treatment of CD since their introduction in the late 1990s, thanks to their ability to induce and maintain remission, heal mucosa, reduce hospital admissions and surgical procedures, and restore quality of life. Despite widespread use of these therapies in CD, their precise mechanism of action remains unclear, although several different mechanisms have been proposed. This review summarizes the biology of the TNF-&agr; cytokine and the development of biological therapies targeting TNF-&agr;, and updates our current understanding of mechanisms of action of the commercially available anti-TNF-&agr; therapies used in the treatment of CD.

Measurement of Labor Quality Growth: Caused by Unobservable Characteristics: caused by unobservable characteristics

The standard economy-wide indices of labor quality (or human capital) largely ignore the role of unobservable worker characteristics. In this paper, we develop a methodology for identifying the contributions of both observable and unobservable worker characteristics in the presence of the incidental parameter problem. Based on data for Switzerland over the period 1991-2006, we find that a large part of growth in labor quality is caused by shifts in the distribution of unobservable characteristics. The contributions to growth attributed to education and age are corrected downwards, if unobservable worker characteristics are taken into account. Yet the standard indices of labor quality appear to be robust to this extension. JEL Classification: J24, J31
