Entrepreneurial Orientation, Human Resources Information Management, and Firm Performance in SMEs

There is abundant literature demonstrating that entrepreneurial orientation has an impact on performance indicators including economic results and relative market share. Moreover, entrepreneurial orientation interacts with market orientation to improve performance. Human resources information management (HRIM) is a critical component of market orientation. We tested a structural model of relationships among entrepreneurial orientation (EO), HRIM, and firm performance using a sample of small and medium sized enterprises (SMEs) from the manufacturing sector of Portugal. EO had a positive direct effect on both performance (β = .313) and HRIM (β = .291). HRIM also had a positive effect on firm performance (β = .236), and EO indirectly impacted firm performance (.069) through HRIM. Copyright © 2011 ASAC. Published by John Wiley & Sons, Ltd.
Clinical and administrative outcomes during publicly-funded inpatient stroke rehabilitation based on a case-mix group classification model.

OBJECTIVES To determine efficiency and efficacy of publicly-funded inpatient stroke rehabilitation based on a Case-Mix Group Classification Model, and to analyse the usefulness of this decisional aid in the refinement of rehabilitation services delivery needed to optimize accessibility to inpatient rehabilitation services for individuals with stroke in a publicly-funded healthcare system. DESIGN Individuals with stroke (n=422) who received inpatient rehabilitation through the Montreal Rehabilitation Hospital Network were included in this retrospective study. Clinical (total, motor and cognitive-Functional Independence Measure (FIM) scores, percentage of discharge to community) and administrative outcomes (onset to rehabilitation interval, length of inpatient rehabilitation stay, length of stay efficiency) were measured. RESULTS Across Case-Mix Groups, mean onset to rehabilitation days varied between 16.2 (5.7) and 32.0 (19.4) days whereas the mean length of stay fluctuated between 27.5 (13) and 77.0 (27) days. Best total (41.6 (21.4)) and motor-FIM (38.9 (19.0)) gains were observed in most severely disabled cases (114) whereas the Case-Mix Group 103 presented the best cognitive-FIM gain (5.8 (4.0)). Optimal mean total, motor and cognitive-FIM efficiency rates, found in moderately disabled stroke patients, were 0.668 (0.434), 0.634 (0.377) and 0.15 (0.136), respectively. Majority of patients returned home following rehabilitation in all Case-Mix Groups (63.6% to 96.4%) except for groups 112 and 108. CONCLUSION Moderate to good length of stay efficiencies are observed among all Case-Mix Group following stroke rehabilitation. In fact, individuals with moderate disability present the best rate of recovery. Variations in length of stay efficiency suggest that the use of a Case-Mix Group Classification Model in stroke rehabilitation could represent an innovative approach, especially for program evaluation in publicly-funded and universal-access rehabilitation hospitals.
Estimating Incidence from Prevalence in Generalised HIV Epidemics: Methods and Validation

Background HIV surveillance of generalised epidemics in Africa primarily relies on prevalence at antenatal clinics, but estimates of incidence in the general population would be more useful. Repeated cross-sectional measures of HIV prevalence are now becoming available for general populations in many countries, and we aim to develop and validate methods that use these data to estimate HIV incidence. Methods and Findings Two methods were developed that decompose observed changes in prevalence between two serosurveys into the contributions of new infections and mortality. Method 1 uses cohort mortality rates, and method 2 uses information on survival after infection. The performance of these two methods was assessed using simulated data from a mathematical model and actual data from three community-based cohort studies in Africa. Comparison with simulated data indicated that these methods can accurately estimates incidence rates and changes in incidence in a variety of epidemic conditions. Method 1 is simple to implement but relies on locally appropriate mortality data, whilst method 2 can make use of the same survival distribution in a wide range of scenarios. The estimates from both methods are within the 95% confidence intervals of almost all actual measurements of HIV incidence in adults and young people, and the patterns of incidence over age are correctly captured. Conclusions It is possible to estimate incidence from cross-sectional prevalence data with sufficient accuracy to monitor the HIV epidemic. Although these methods will theoretically work in any context, we have able to test them only in southern and eastern Africa, where HIV epidemics are mature and generalised. The choice of method will depend on the local availability of HIV mortality data.
Assessment and evaluation of psychological distress in HIV-infected Women

Abstract HIV-infected women are an increasingly larger group among the risk groups in Germany. In order to illuminate the psychological situation of HIV-infected women in Germany, 100 women with HIV disease were enrolled in a basic study. 71% of the patients were intravenous (IV) drug addicted and 29% were infected through other means. The study population comprised patients in all stages of the Walter Reed Classification System. We found 52% in the first stages, 28% in ARC, 8% in WR 5 and 12% in WR 6. Evaluated data included medical, socio-demographic and information regarding the patients' history of drug abuse. The SCL-90-R, a psychological symptom inventory, was applied as well as two paper and pencil tests on coping strategies and social support. We also interviewed several HIV-infected women to investigate their individual situations and coping strategies Questions about differences between the two groups of HIV-infected women (IV drug addicted vs non-drug addicted) were answered first. Second, we d.
Evaluation of reflective practice in teacher education

Teacher education based on ‘reflective practice’ consists of observing, analysing and reflecting on teacher performance in order to improve professional practice. This article presents the results of an evaluation of a programme on mathematics teaching carried out using reflective practice. It was targeted at 284 teachers in various stages of the education system, using an approach that combines quantitative (surveys) and qualitative (interviews and reports) methods. While the study shows that the education programme generates high levels of satisfaction, pedagogical appropriateness and learning, its achievements in effectiveness are moderate. Although, in general, what is learned through teacher education is implemented in the classroom, it is done so in an isolated fashion, in other words, individually and without becoming a part of the culture of the school. The results show little evidence of its impact on student learning. The article offers proposals for improving the education programme, while, at the same time, analysing the usefulness of the approach and evaluation tools employed.
Repeatability of Autofluorescence Lifetime Imaging at the Human Fundus in Healthy Volunteers

Abstract Purpose: We aim to evaluate the repeatability of a new fluorescence lifetime imaging (FLIM) technique which measures time-resolved autofluorescence to assess metabolism of the retina. Materials and methods: We performed FLIM with two spectral channels (channel 1: 490–560 nm and channel 2: 560–700 nm) on 10 healthy volunteers, with 10 replicates per volunteer. From the 30° fundus FLIM images, we selected three regions: the fovea, the optic disc and the papillo-macular bundle. For each channel in these regions, we determined an average multi-exponential approximation with three components, and the six resulting parameters, α1–α3 (amplitudes) and τ1–τ3 (fluorescence lifetimes), were analyzed in terms of the coefficient of variation (CV). Results: Repeatability was highest in the papillo-macular bundle, followed by the fovea and the optic disc. Repeatability was higher in channel 1 (mean CV of 7.9%) than in channel 2 (mean CV of 17.7%). The average CV for the diagnostically most relevant channel 1 and the most relevant parameters was as follows: τ1 (5.5%) and τ2 (4.7%) in the papillo-macular bundle, and τ1 (6.8%) and τ2 (6.9%) in the fovea. Conclusions: We demonstrated repeatability of FLIM measurement results within acceptable ranges of variation. Based on the detailed coefficients of variation, we derived recommendations for parameter ranges suitable for diagnostic applications.
Efficient and Privacy-Preserving Data Aggregation Scheme for Smart Grid Against Internal Adversaries

Privacy-preserving data aggregation (P2DA) is an important basic building block that can protect consumer’s privacy in the smart grid environment because it could be used to prevent the extraction of the electricity consumption information of a specific consumer. Due to this important function, the P2DA scheme for the smart grid has attracted a lot of attention from both academic and industry researchers who have proposed many P2DA schemes for the smart grid in recent years. However, most of these P2DA schemes are not secure against internal attackers or cannot provide data integrity. Besides, their computation costs are not satisfactory because the bilinear pairing operation or the hash-to-point operation is performed at the smart meter’s side. To address the deficiencies of previous schemes, we propose a new P2DA scheme against internal attackers using Boneh–Goh–Nissim public key cryptography. The proposed P2DA scheme does not use bilinear pairing or hash-to-point operation making it be more computationally efficient than previous P2DA schemes. We also show that the proposed P2DA scheme is provably secure and can meet various security requirements.
Cities as Battlespace: The New Military Urbanism

The latest in an ongoing series of papers on the links between militarism and urbanism published in City, this paper opens with an exploration of the emerging crossovers between the ‘targeting’ of everyday life in so‐called ‘smart’ border and ‘homeland security’ programmes and related efforts to delegate the sovereign power to deploy lethal force to increasingly robotized and automated war machines. Arguing that both cases represent examples of a new military urbanism, the rest of the paper develops a thesis outlining the scope and power of contemporary interpenetrations between urbanism and militarism. The new military urbanism is defined as encompassing a complex set of rapidly evolving ideas, doctrines, practices, norms, techniques and popular cultural arenas through which the everyday spaces, sites and infrastructures of cities—along with their civilian populations—are now rendered as the main targets and threats within a limitless ‘battlespace’. The new military urbanism, it is argued, rests on five related pillars; these are explored in turn. Included here are the normalization of militarized practices of tracking and targeting everyday urban circulations; the two‐way movement of political, juridical and technological techniques between ‘homeland’ cities and cities on colonial frontiers; the rapid growth of sprawling, transnational industrial complexes fusing military and security companies with technology, surveillance and entertainment ones; the deployment of political violence against and through everyday urban infrastructure by both states and non‐state fighters; and the increasingly seamless fusing of militarized veins of popular, urban and material culture. The paper finishes by discussing the new political imaginations demanded by the new military urbanism.
Screening of the LTBP2 gene in a north Indian population with primary congenital glaucoma

Purpose Primary congenital glaucoma (PCG), a severe form of glaucoma that presents early in life, is an autosomal recessive eye disorder that results from defects in anterior eye segment. Null mutations in LTBP2 were reported in patients with PCG in Pakistani and Iranian families. This study was aimed to identify the mutation profile of the LTBP2 gene in north Indian patients with PCG. Methods After ethical clearance, 54 unrelated patients with PCG who were either negative or heterozygous for MYOC, CYP1B1, and FOXC1 mutations and 50 ethnically matched non-glaucomatous controls were recruited for the study. PCG diagnosis was established by the presence of buphthalmos in at least one affected eye and associated high intraocular pressure before the age of 3 years. LTBP2 was screened in genomic blood DNA for mutations, with PCR and direct sequencing of PCR amplified fragments. Results We observed one intronic single nucleotide polymorphism (rs3742793) between exons 6 and 7 in the LTBP2 gene in 18 patients with PCG. This nucleotide change resulted in cytosine (C) being replaced by guanosine (G) at position g.75070493. No pathogenic variants were identified in the LTBP2 gene in our cohort of patients. Conclusions LTBP2 gene mutations are not involved in the pathogenesis of primary congenital glaucoma in our patients. Thus, it is important to screen other glaucoma-associated loci and genes for involvement in congenital glaucoma in cases that are either negative or heterozygous for MYOC, CYP1B1, and FOXC1 mutations to have better insight into the disease pathogenesis.
Parents' Workplace Experiences and Family Communication Patterns

Data gathered from 178 parents of adolescent children are used to elucidate observed relationships between social class and family communication patterns. The results—that parents generalize from their own life experiences, particularly in the workplace—are consistent with Kohn's theory of learning generalization: Conversation orientation is positively associated and conformity orientation is negatively associated with the degree of openness and autonomy in workplace communication. In this sample, the effect is stronger among women than among men.
Semantic state space for high-level maneuver planning in structured traffic scenes

Originating from simple cruise control systems that monitor and control the speed of the vehicle, driver assistance systems have evolved into intelligent systems. Future assistance systems will combine information from different sensors and data sources to build up a model of the current traffic scene. This way they will be able to assist in challenging tasks in complex situations. Towards this goal, we present a semantic scene representation for modeling traffic scenes. Based on a geometric representation a semantic representation is defined using an ontology to model relevant traffic elements and relations. Considering potential relations of the ego vehicle, a semantic state space of the ego vehicle is derived. Transitions are defined that model state changes (maneuvers). The model can be used for example for situation analysis and high level planning for driving hint generation or automated driving. The method is evaluated in different traffic situations and on real sensor data. It is going to be applied to (semi-)automated driving in a real test vehicle.
Embedded Firms, Embedded Knowledge: Problems of Collaboration and Knowledge Transfer in Global Cooperative Ventures

Research on global cooperative ventures has tended to focus on governance forms and task structures. This study highlights the importance of knowledge structures and work systems in influencing the success of collaborative ventures. Based on an empirical analysis of a close collaboration in the knowledge-intensive area between a Japanese and a British high-technology firm, it illustrates how the socially embedded nature of knowledge can impede cross-border collaborative work and knowledge transfer. The research has applied and extended Michael Polanyi's con cept of 'tacit knowledge' in a much wider context. It develops a conceptual frame work for analyzing the main differences and 'points of friction' between the Japanese 'organizational' and the British 'professional' models of the organization of knowledge in high-level technical work. It shows how the dominant form of knowledge held in organizations, its degree of tacitness, and the way in which it is structured, utilized and transmitted can vary considerably between firms in dif ferent societal settings. These differences are shown to have contributed to project failures, weakened the technological relationship between the partner firms over time and led to asymmetry in knowledge transfer.
Exercise Does Not Influence Myostatin and Follistatin Messenger RNA Expression in Young Women

Jensky, NE, Sims, JK, Dieli-Conwright, CM, Sattler, FR, Rice, JC, and Schroeder, ET. Exercise does not influence myostatin and follistatin messenger RNA expression in young women. J Strength Cond Res 24(2): 522-530, 2010-We evaluated changes in myostatin, follistatin, and MyoD messenger RNA (mRNA) gene expression using eccentric exercise (EE) and concentric exercise (CE) as probes to better understand the mechanisms of muscle hypertrophy in young women. Twelve women performed single-leg maximal eccentric (n = 6, 25 ± 1 years, 59 ± 7 kg) or concentric (n = 6, 24 ± 1 years, 65 ± 7 kg) isokinetic knee extension exercise for 7 sessions. Muscle biopsies were taken from the vastus lateralis at baseline, 8 hours after the first exercise session, and 8 hours after the seventh exercise session. In the EE group, there were no changes in myostatin and follistatin (p ≥ 0.17); however, MyoD expression increased after 1 exercise bout (p = 0.02). In the CE group, there were no changes in myostatin, follistatin, or MyoD mRNA gene expression (p ≥ 0.07). Differences between the EE and CE groups were not significant (p ≥ 0.05). These data suggest that a single bout or multiple bouts of maximal EE or CE may not significantly alter myostatin or follistatin mRNA gene expression in young women. However, MyoD mRNA expression seems to increase only after EE.
Feigin – Frenkel center in types

For each simple Lie algebra g consider the corresponding affine vertex algebra Vcrit(g) at the critical level. The center of this vertex algebra is a commutative associative algebra whose structure was described by a remarkable theorem of Feigin and Frenkel about two decades ago. However, only recently simple formulas for the generators of the center were found for the Lie algebras of type A following Talalaev’s discovery of explicit higher Gaudin Hamiltonians. We give explicit formulas for generators of the centers of the affine vertex algebras Vcrit(g) associated with the simple Lie algebras g of types B, C and D. The construction relies on the Schur–Weyl duality involving the Brauer algebra, and the generators are expressed as weighted traces over tensor spaces and, equivalently, as traces over the spaces of singular vectors for the action of the Lie algebra sl2 in the context of Howe duality. This leads to an explicit construction of a commutative subalgebra of the universal enveloping algebra U(g[t]) and to higher order Hamiltonians in the Gaudin model associated with each Lie algebra g. We also introduce analogues of the Bethe subalgebras of the Yangians Y(g) and show that their graded images coincide with the respective commutative subalgebras of U(g[t]).

Preventive care in the emergency department: screening for domestic violence in the emergency department.

OBJECTIVES The most effective methods for identification and management of domestic violence (DV) victims in health care settings are unknown. The objective of this study was to systematically review screening for DV in the emergency department (ED) to identify victims and decrease morbidity and mortality from DV. METHODS Using the terms "domestic violence" or "partner violence," and "identification" or "screening," and "emergency," the authors searched MEDLINE, the Cochrane Database, and Emergency Medical Abstracts from 1980-2002. They selected articles studying screening tools, interventions, or determining the incidence or prevalence of DV among ED patients. The studies were analyzed using evidence-based methodology. RESULTS Three hundred thirty-nine articles resulted from the literature search. Based on selection criteria, 45 were reviewed in detail and 17 pertained to the ED. From references of these 17 articles, three additional articles were added. Screening can be conducted using a brief verbal screen and existing ED personnel. A randomized, controlled trial did not demonstrate a difference in screening rates between experimental and control hospitals. No studies assessed the effect of ED screening for DV on morbidity or mortality of domestic violence. An ED-based advocacy program resulted in increased use of shelters and counseling. CONCLUSIONS Because of the paucity of outcomes research evaluating ED screening and interventions, there is insufficient evidence for or against DV screening in the ED. However, because of the high burden of suffering caused by DV, health care providers should strongly consider routinely inquiring about DV as part of the history, at a minimum for all female adolescent and adult patients.
A Trust Model Based on the Extended Subjective Logic for P2P Networks

In order to alleviate the lack of trust in P2P environment, a malicious node attacks and so on, through the expansion of Josang subjective logic thought, proposed a extended subjective logic based on extended P2P trust model ESL-TM. In order to describe the complexity of trust relationships more effectively, positive and negative trust value are used to replace positive and negative events used in subjective logic. Also introduce the time decay factor and risk factors to calculate the trust degree of a node. Simulation results and analysis show that the model is more sensitive to malicious behaviors can effectively enhance the resilience against malicious nodes to improve the system the proportion of successful transactions.
Twisted self-deception

In instances of "twisted" self-deception, people deceive themselves into believing things that they do not want to be true. In this, twisted self-deception differs markedly from the "straight" variety that has dominated the philosophical and psychological literature on self-deception. Drawing partly upon empirical literature, I develop a trio of approaches to explaining twisted self-deception: a motivation-centered approach; an emotion-centered approach; and a hybrid approach featuring both motivation and emotion. My aim is to display our resources for exploring and explaining twisted self-deception and to show that promising approaches are consistent with a plausible position on straight self-deception.
Evaluation of chemotherapy drug exposure at a veterinary teaching hospital in Michigan.

In February 2010, the National Institute for Occupational Safety and Health (NIOSH) received a confidential employee request for a Health Hazard Evaluation (HHE) at a veterinary teaching hospital that provides routine care and oncology services to large and small animals. Canines and felines constitute the majority of the oncology department’s patients. Veterinary hospital employees were concerned about adverse health effects from the use of chemotherapy drugs in the oncology department. In 2004, NIOSH released an Alert regarding occupational exposures to antineoplastic and other hazardous drugs that are used in health care settings. Hazardous drugs were defined in the NIOSH Alert as having “specific health effects (such as skin rashes, cancer, and reproductive effects) and high toxicity at low doses. ”(1) The NIOSH Alert also described best practices for handling, storage, disposal, and decontamination procedures and was updated in 2010 and 2012 to include an expanded list of hazardous drugs. (2,3) Also in 2010, NIOSH released a Workplace Solutions document to increase awareness of occupational safety and health issues in veterinary health care workers who work with antineoplastic and hazardous drugs.
