Faculty perspectives regarding the importance and place of nontechnical competencies in veterinary medical education at five North American colleges of veterinary medicine.

OBJECTIVE To explore perceptions of faculty educators regarding the importance of nontechnical competencies in veterinary graduates and the placement of nontechnical competency development in veterinary education. DESIGN Survey. SAMPLE POPULATION All faculty members at 5 North American veterinary medical institutions. PROCEDURES Participants rated the importance of 14 nontechnical competencies and indicated in which phase or phases of veterinary education such competencies should be developed (ie, curriculum placement). Differences in mean ratings were statistically evaluated, as were associations between ratings or curriculum placement and respondent institution, gender, experience, and discipline. RESULTS Mean ratings of importance were above neutral for all competencies and were highest for ethical, critical thinking, and interpersonal and intrapersonal competencies; development of these competencies was favored in preveterinary and veterinary training. Ratings were lower for management and business competencies; development of these and other competencies was placed primarily in the clinical phase of the veterinary curriculum. Basic science, nonveterinarian, and junior faculty appeared to more strongly appreciate the importance of nontechnical skills, whereas large animal and midcareer faculty reported a more reserved degree of support. Female faculty were more likely to place nontechnical competency development throughout the educational process. CONCLUSIONS AND CLINICAL RELEVANCE Participants agreed nontechnical competencies are important for veterinary graduates; however, faculty perceptions differed from previously published findings regarding the relative importance of business and management skills. Those involved in faculty hiring, faculty development, and curricular planning should also be aware of disciplinary and career stage differences affecting faculty perspectives.
Evaluating the Predictive Accuracy of Volatility Models

Standard statistical loss functions, such as mean-squared error, are commonly used for evaluating financial volatility forecasts. In this paper, an alternative evaluation framework, based on probability scoring rules that can be more closely tailored to a forecast user's decision problem, is proposed. According to the decision at hand, the user specifies the economic events to be forecast, the scoring rule with which to evaluate these probability forecasts, and the subsets of the forecasts of particular interest. The volatility forecasts from a model are then transformed into probability forecasts of the relevant events and evaluated using the selected scoring rule and calibration tests. An empirical example using exchange rate data illustrates the framework and confirms that the choice of loss function directly affects the forecast evaluation results.

The Australian mining industry and the ideal mining woman: Mobilizing a public business case for gender equality

Despite ongoing ‘boom’ conditions in the Australian mining industry, women remain substantially and unevenly under-represented in the sector, as is the case in other resource-dependent countries. Building on the literature critiquing business-case rationales and strategies as a means to achieve women’s equality in the workplace, we examine the business case for employing more women as advanced by the Australian mining industry. Specifically, we apply a discourse analysis to seven substantial, publically-available documents produced by the industry’s national and state peak organizations between 2005 and 2013. Our study makes two contributions. First, we map the features of the business case at the sectoral rather than firm or workplace level and examine its public mobilization. Second, we identify the construction and deployment of a normative identity – ‘the ideal mining woman’ – as a key outcome of this business-case discourse. Crucially, women are therein positioned as individually responsible for gender equality in the workplace.
Reliable Communication in Wireless Body Area Sensor Network for Health Monitoring

Now days , interests in the application of Wireless Body Area Network (WBAN) have grown considerably. A number of tiny wireless sensors, strategically placed on the human body, create a wireless body area network that can monitor various vital signs, providing real-time feedback to the user and medical personnel. This communication needs to be energy efficient and highly reliable while keeping delays low. In this paper we present hardware and software architecture for BAN and also we offer reliable communication and data aggregation.
Circulating endothelial cells are elevated in patients with type 1 diabetes mellitus.

OBJECTIVE Circulating endothelial cells (CECs) have emerged as vascular damage markers and are increased in type 2 diabetic patients. Since type 1 diabetes is associated with vascular damage, we hypothesized high CEC numbers in this patient population. METHODS Thirty-nine patients with type 1 diabetes and 39 controls were included. CECs were isolated using anti-CD146-coated Dynabeads, stained with Ulex lectin-1, and counted by fluorescence microscopy. Endothelial function was measured as flow-mediated dilation (FMD). Thiobarbituric acid reactive substances (TBARS), total glutathione levels (GSH), and paraoxonase (PON) activity levels were measured as oxidative stress markers. RESULTS Patients with type 1 diabetes mellitus had higher number of CECs (7.46+/-5.37 vs 2.13+/-1.13 cells/ml, P<0.001), lower FMD (7.87+/-2.19 vs 12.06+/-2.34%, P<0.001), higher TBARS (4.94+/-1.20 vs 3.07+/-0.75 nmol/MDA, P<0.001), lower GSH (206.12+/-98.06 vs 353.61+/-68.45 microM, P<0.001), and lower PON activity levels (89.10+/-17.82 vs 127.65+/-29.01 U/l, P<0.001) as compared to controls. There was positive correlation between CEC numbers and HbAlc levels (r=0.49, P=0.002). CECs and fasting glucose levels were not correlated. There was no correlation between the number of CECs and FMD. Furthermore, there were no correlations between the number of CECs and TBARS, GSH and PON activity levels. Multiple regression analysis showed that HbAlc levels (r(2)=0.40, P<0.009) were associated with CEC numbers. CONCLUSION CECs are elevated in patients with type 1 diabetes mellitus reflecting endothelial damage. This increase is dependent on long-term glucose control.
DTI of human skeletal muscle: the effects of diffusion encoding parameters, signal‐to‐noise ratio and T2 on tensor indices and fiber tracts

In this study, we have performed simulations to address the effects of diffusion encoding parameters, signal‐to‐noise ratio (SNR) and T2 on skeletal muscle diffusion tensor indices and fiber tracts. Where appropriate, simulations were corroborated and validated by in vivo diffusion tensor imaging (DTI) of human skeletal muscle. Specifically, we have addressed: (i) the accuracy and precision of the diffusion parameters and eigenvectors at different SNR levels; (ii) the effects of the diffusion gradient direction encoding scheme; (iii) the optimal b value for diffusion tensor estimation; (iv) the effects of changes in skeletal muscle T2; and, finally, the influence of SNR on fiber tractography and derived (v) fiber lengths, (vi) pennation angles and (vii) fiber curvatures. We conclude that accurate DTI of skeletal muscle requires an SNR of at least 25, a b value of between 400 and 500 s/mm2, and data acquired with at least 12 diffusion gradient directions homogeneously distributed on half a sphere. Furthermore, for DTI studies focusing on skeletal muscle injury or pathology, apparent changes in the diffusion parameters need to be interpreted with great care in view of the confounding effects of T2, particularly for moderate to low SNR values.

Ownership structure, corporate diversification and capital structure: evidence from China's publicly listed firms

Purpose – The purpose of this paper is to investigate whether, and to what extent, corporate diversification into related and unrelated businesses affects capital structure choices, and whether ownership structure is germane to the understanding of corporate diversification strategies and debt‐equity financing choices.Design/methodology/approach – Univariate approaches include the parametric two‐sample t‐test, non‐parametric Kolmogorov‐Smirnov test and Kruskal‐Wallis rank test, and cluster analysis. Multivariate approaches include panel data regressions to identify the sign and magnitude of the effect of diversification on capital structure, after controlling for a number of industry and firm characteristics as suggested in the literature.Findings – Corporate diversification into related or unrelated industries has opposite effects on capital structure, after controlling for ownership structure and corporate governance mechanisms. Consistent with the prediction of organizational economics, an increase in .
The treatment of acute bronchitis by general practitioners in the UK. Results of a cross sectional postal survey.

BACKGROUND In Australia and the UK acute bronchitis is a common presenting problem in general practice. When symptoms persist management can be difficult and despite evidence that antibiotics are usually ineffective their use is widespread. OBJECTIVE To describe prescribing behaviour for acute bronchitis by general practitioners in the United Kingdom. METHOD Cross sectional postal survey of UK GPs. RESULTS Four hundred and nineteen (73%) GPs responded. Purulent sputum, fever and crepitations/crackles on chest examination were the most important reasons for prescribing antibiotics: 89% of GPs said the colour of the sputum influenced their decision; amoxycillin was the first choice; 40% of GPs believed that at least one in five consultations for ARI were affected by patient factors, usually to maintain patient satisfaction. 47% of GPs advised the use of bronchodilators, and 96% recommended the symptomatic use of paracetamol and fluids. CONCLUSION General practitioners are influenced to use antibiotics by patient symptoms and signs for which there is little evidence. Patient psychosocial factors influence prescribing. Until clearer research findings from new studies are available, GPs may opt for a 'just in case' prescription.
The Political Economy of Terrorism: Subject Index

The Political Economy of Terrorism presents a widely accessible political economy approach to the study of terrorism. It applies economic methodology â€“ theoretical and empirical â€“ combined with political analysis and realities to the study of domestic and transnational terrorism. In so doing, the book provides both a qualitative and quantitative investigation of terrorism in a balanced up-to-date presentation that informs students, policy makers, researchers and the general reader of the current state of knowledge. Included are historical aspects, a discussion of watershed events, the rise of modern-day terrorism, examination of current trends, the dilemma of liberal democracies, evaluation of counterterrorism, analysis of hostage incidents and much more. The new edition expands coverage of every chapter, adds a new chapter on terrorist network structures and organization, accounts for changes in the Department of Homeland Security and the USA Patriot Act and insurance against terrorism. Rational-actor models of terrorist and government behavior and game-theoretic analysis are presented for readers with no prior theoretical training. Where relevant, the authors display graphs using data from International Terrorism: Attributes of Terrorist Events (ITERATE), the Global Terrorism Database (GTD), and other public-access data sets.
Occupational Communities: Culture and Control in Organizations

Abstract : The organization is but one frame of reference for understanding work behavior. Equally powerful but largely unexplored social forces in the workplace are groups sired by the perception of common task. After developing the concept of an occupational community as a framework for analyzing the phenomenological boundaries of work worlds, the authors show how research on occupational communities can broaden our knowledge of careers, control, conflict, and innovation, topics traditionally approached from an organizational perspective.
AsonMaps: A platform for aggregation visualization and analysis of disaster related human sensor network observations

In this paper, we describe AsonMaps, a platform for collection, aggregation, visualization and analysis of near real-time, geolocated quantifiable information from a variety of heterogeneous social media outlets in order to provide emergency responders and other coordinating federal agencies not only with the means of listening to the affected population, but also to be able to incorporate this data into geophysical and probabilistic disaster forecast models that guide their response actions. Hurricane Sandy disaster is examined as a use-case scenario discussing the different types of quantifiable information that can be extracted from Instagram and Twitter
Aqueous photochemistry of triclosan: Formation of 2,4‐dichlorophenol, 2,8‐dichlorodibenzo‐p‐dioxin, and oligomerization products

The photochemical fate of the antimicrobial agent triclosan is presented. Experiments performed in both natural and buffered deionized water show that triclosan rapidly photodegrades by direct photolysis (t½ = 5 h, pH 8, noon summer sunlight, 45°N latitude). Both 2,8‐dichlorodibenzo‐p‐dioxin (2,8‐DCDD) and 2,4‐dichlorophenol (2,4‐DCP) are produced. The 2,8‐DCDD and 2,4‐DCP also are photolabile and, thus, are intermediates. The yields for 2,8‐DCDD and 2,4‐DCP ranged from 3 to 12% depending on the conditions employed. When triclosan is photolyzed in the presence of Suwannee River (GA, USA) fulvic acid, a portion of the initial mass is recovered as insoluble material. Based on experiments in which the formation of insoluble material was monitored with photolysis time, it is postulated that photolysis in natural waters leads to some of the triclosan being coupled to humic matter. Triclosan also reacts rapidly with both singlet oxygen (krxn = 1.07 ± 0.03 × 108 M−1 s−1 in water of pH 10) and hydroxyl radical (k·OH = 5.4 ± 0.3 × 109 M−1 s−1). Indirect photolysis pathways, however, are not expected to be important because of low steady‐state concentrations of reactive oxygen species in natural waters and the efficiency of the direct photolysis of triclosan.
Mendelian randomization analysis of a time‐varying exposure for binary disease outcomes using functional data analysis methods

A Mendelian randomization (MR) analysis is performed to analyze the causal effect of an exposure variable on a disease outcome in observational studies, by using genetic variants that affect the disease outcome only through the exposure variable. This method has recently gained popularity among epidemiologists given the success of genetic association studies. Many exposure variables of interest in epidemiological studies are time varying, for example, body mass index (BMI). Although longitudinal data have been collected in many cohort studies, current MR studies only use one measurement of a time‐varying exposure variable, which cannot adequately capture the long‐term time‐varying information. We propose using the functional principal component analysis method to recover the underlying individual trajectory of the time‐varying exposure from the sparsely and irregularly observed longitudinal data, and then conduct MR analysis using the recovered curves. We further propose two MR analysis methods. The first assumes a cumulative effect of the time‐varying exposure variable on the disease risk, while the second assumes a time‐varying genetic effect and employs functional regression models. We focus on statistical testing for a causal effect. Our simulation studies mimicking the real data show that the proposed functional data analysis based methods incorporating longitudinal data have substantial power gains compared to standard MR analysis using only one measurement. We used the Framingham Heart Study data to demonstrate the promising performance of the new methods as well as inconsistent results produced by the standard MR analysis that relies on a single measurement of the exposure at some arbitrary time point.
Clinical effectiveness of single lumbar transforaminal epidural steroid injections.

OBJECTIVES To assess the clinical effectiveness of single lumbar transforaminal epidural steroid injections (TFESIs) in subjects with radicular pain with or without radiculopathy. DESIGN Retrospective observational series. SETTING Single academic radiology pain management practice. SUBJECTS Two thousand twenty-four subjects undergoing single lumbar TFESIs at the L4-5, L5-S1, or S1 neural foramina. METHODS / OUTCOME MEASURES Subjects were assessed with a pain numerical rating scale (NRS, 0-10) and Roland-Morris disability questionnaire (R-M, 23-point Deyo modification) prior to TFESI and at 2 weeks and 2 months follow-up. Successful pain relief (responders) was defined as either ≥50% reduction in NRS or pain 0/10; functional success was defined as ≥40% reduction in R-M score. RESULTS There were statistically significant (P < 0.0001) reductions in mean NRS and R-M scores at 2 weeks and 2 months postinjection. For NRS, 40.9% were responders at 2 weeks and 45.6% at 2 months. For R-M, 31.9% were responders at 2 weeks and 41.3% at 2 months. The proportion of responders for NRS and R-M was higher when there was <3 months of pain (odds ratio 2-month NRS = 2.42 [95% confidence interval: 1.82, 3.24], odds ratio 2-month R-M = 2.61 [1.96, 3.48]). For subjects with <3 months of pain, the proportion of responders was 62.4% (56.5, 68.3%) for NRS and 59.3% (53.3, 65.3%) for R-M scores. CONCLUSIONS This retrospective observational study suggests TFESIs are clinically effective in the treatment of lumbar radicular pain. Subjects with a shorter duration of pain are more likely to achieve a successful outcome.
The Road to Sustainability: Exploring the Process of Corporate Environmental Strategy Over Time

We explore corporate environmental strategy over time, investigating the patterns of evolving environmental investment decisions. Longitudinal case studies provide evidence that environmental strategy evolves through a feedback process, wherein outcomes of earlier decisions have an impact on subsequent decisions. Specifically, positive feedback from outcomes like innovation triggers higher goals, enhancing the undertaking of advanced investments, whereas negative feedback from outcomes, such as increased costs, decelerates the adoption of further investments. The study points to an emergent view of environmental strategy, where capabilities that are gradually developed in concomitance with environmental outcomes lead to an upgrading of environmental goals, thus triggering the feedback process. The process eventually culminates in higher levels of environmental conduct, being more and more integrated with business strategy and competitive advantage. Managers’ values and environmental attitudes influence environmental decisions and actions, affecting the acceleration of the feedback process and the magnitude of responses. Managerial implications are discussed.
Lumbar degenerative spinal deformity: Surgical options of PLIF, TLIF and MI-TLIF

Degenerative disease of the lumbar spine is common in ageing populations. It causes disturbing back pain, radicular symptoms and lowers the quality of life. We will focus our discussion on the surgical options of posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for lumbar degenerative spinal deformities, which include symptomatic spondylolisthesis and degenerative scoliosis. Through a description of each procedure, we hope to illustrate the potential benefits of TLIF over PLIF. In a retrospective study of 53 ALIF/PLIF patients and 111 TLIF patients we found reduced risk of vessel and nerve injury in TLIF patients due to less exposure of these structures, shortened operative time and reduced intra-operative bleeding. These advantages could be translated to shortened hospital stay, faster recovery period and earlier return to work. The disadvantages of TLIF such as incomplete intervertebral disc and vertebral end-plate removal and potential occult injury to exiting nerve root when under experienced hands are rare. Hence TLIF remains the mainstay of treatment in degenerative deformities of the lumbar spine. However, TLIF being a unilateral transforaminal approach, is unable to decompress the opposite nerve root. This may require contralateral laminotomy, which is a fairly simple procedure. The use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to treat degenerative lumbar spinal deformity is still in its early stages. Although the initial results appear promising, it remains a difficult operative procedure to master with a steep learning curve. In a recent study comparing 29 MI-TLIF patients and 29 open TLIF, MI-TLIF was associated with longer operative time, less blood loss, shorter hospital stay, with no difference in SF-36 scores at six months and two years. Whether it can replace traditional TLIF as the surgery of choice for degenerative lumbar deformity remains unknown and more studies are required to validate the safety and efficiency.
Transaction cost economics: a theory for internal audit?

Compared to external audit, internal audit has been charged with having no theory to guide academic research and practice. Suggests that the claims that internal audit has no theory have overlooked the theory of transaction cost economics. A variation of agency theory, transaction cost economics provides a conceptual framework for internal audit. Explains the theory that transaction cost economics provides for internal audit, and tests the theory with an experiment involving the usefulness of internal audit findings for senior executives in government organizations.
Did Regulation Fair Disclosure Affect Credit Markets?

This study assesses whether the implementation of Regulation Fair Disclosure (Reg FD) has affected the quantity and quality of information in credit markets. We find that, after Reg FD, borrowing from new lenders was associated with a higher loan spread. We also document that, after Reg FD, (1) borrowers became more dependent on relationship lending; (2) lead lenders retained a higher loan share; and (3) a typical loan syndicate involved a smaller number of participating lenders. We interpret these results as evidence of an increased level of information asymmetry in credit markets after Reg FD.
Dimensioning of Energy Storage for Increased Integration of Wind Power

Energy storage can potentially allow for more production from renewable resources into existing grids. A methodology to quantify grid limitations and dimension battery energy storage systems is presented in this paper. By use of grid consumption and production data, the hosting capacity methodology is developed as a general framework for storage dimensioning that can be applied by grid operators. The method is successfully applied to an existing subtransmission grid; actual hourly production and consumption data during a two-year period is used. The role of a storage system compared to other means to handle overloading is studied. It is found that about one third of overloading instances are suitable to handle with a battery energy storage system. After this, diminishing returns per unit of storage capacity are shown to occur.
Differential attenuation of oxidative/nitrosative injuries in early prostatic neoplastic lesions in TRAMP mice by dietary antioxidants

Dietary antioxidants with yet unproven efficacies in averting prostate cancer (PCa) are widely used in the United States as preventives. Experimental evidence establishing a causal relationship between oxidative and nitrosative stress (OS/NS) and PCa development and showing its modulation by dietary antioxidants would help justify their usage.
