Matchplay characteristics of Grand Slam tennis: implications for training and conditioning

ABSTRACT The purpose of this study was to probe the sex-based differences in the stroke and movement dynamics of Grand Slam hard-court tennis. Player and ball tracking data were collated for 102 male and 95 female players during the 2012–2014 Australian Open tournaments. Serve, serve return, groundstroke and movement data were compared between sexes. Serve statistics were the subject of the largest differences, with males achieving significantly faster speeds, aces and unreturned serves while also winning a greater percentage of service points. When returning serve, women contacted the ball closer to the net, lower to the ground and achieved flatter ball trajectories than males. Groundstroke frequencies were similar between sexes, although males hit with greater speed, flatter trajectories and impacted more shots inside the baseline. Distance covered per set or during points won or lost was not sex dependent, yet men exhibited faster average movement speeds. These findings highlight the need for sex-specific training and practice designs that cater to the different stroke dynamics, particularly in relation to the first serve and serve-return, as well as movement speeds.
Performance Outcomes of Turnover Intentions in Temporary Organizations: A Dyadic Study on the Effects at the Individual, Team, and Organizational Level

This research examines the link between turnover intentions from temporary and permanent organizations and how both types of turnover intentions affect employee performance at an individual, temporary and permanent organizational level. Using dyadic data from 253 team members and their supervisors we find that turnover intentions from temporary organizations significantly enhance turnover intentions from permanent organizations, which leads to decreasing performance at all three levels. A moderation analysis suggests that companies can reduce detrimental effects of turnover intentions from temporary organizations by providing transparency and possibilities to participate in staffing processes. Our paper contributes to research on the performance effects of employee turnover intentions by: (1) analyzing effects of turnover intentions from temporary organizations; (2) investigating the interplay between turnover intentions from temporary organizations and the permanent organization; and (3) considering performance effects at three different organizational levels.
Viral Ribonucleoprotein Complex Formation and Nucleolar-Cytoplasmic Relocalization of Nucleolin in Poliovirus-Infected Cells

ABSTRACT The poliovirus 3′ noncoding region (3′NCR) is involved in the efficient synthesis of viral negative-stranded RNA molecules. A strong interaction between a 105-kDa host protein and the wild-type 3′NCR, but not with a replication-defective mutant 3′NCR, was detected. This 105-kDa protein was identified as nucleolin which predominantly resides in the nucleolus and has been proposed to function in the folding of rRNA precursor molecules. A functional role for nucleolin in viral genome amplification was examined in a cell-free extract which has been shown to support the assembly of infectious virus from virion RNA. At early times of viral gene expression, extracts depleted of nucleolin produced less infectious virus than extracts depleted of fibrillarin, another resident of the nucleolus, indicating a functional role of nucleolin in the early stages of the viral life cycle in this in vitro system. Immunofluorescence analysis of uninfected and infected cells showed a nucleocytoplasmic relocalization of nucleolin, but not of fibrillarin, in poliovirus-infected cells. Relocalization of nucleolin was not simply a consequence of virally induced inhibition of translation or transcription, because inhibitors of translation or transcription did not induce nucleolar-cytoplasmic relocalization of nucleolin. These findings suggest a novel virus-induced mechanism by which certain nucleolar proteins are selectively redistributed in infected cells.
How effective is an incremental ACE in addressing the debt bias? Evidence from corporate tax returns

The Allowance for Corporate Equity (ACE) introduced in Italy in 2011 has decreased the fiscal distortion between the costs of equity and debt by introducing the deductibility from taxable income of a notional return on capital increases. In this paper, we estimate the impact of the ACE on the leverage ratio of Italian manufacturing firms. Using a novel instrumental variable approach to identify the causal effect, we find that the introduction of the incremental ACE has substantially reduced the leverage ratio of its beneficiaries. We find that the effect is larger for smaller enterprises and for mature firms. In addition, the impact of the ACE is higher for vulnerable and risky firms than for sound firms. These results suggest that an incremental ACE may be an effective policy tool to reduce the leverage ratio of European firms.
Innovative regional development through triple helix collaboration: a comparative case study of strategic structures and implementation

Intense global competition forces regions to seek new ways to boost innovativeness and the success of local enterprises. This paper focuses on triple helix collaboration to support regional innovation-led development and economy. Various options exist for structuring and implementing triple helix collaboration. However, current empirical knowledge is inadequate for stakeholders interested and involved in regional strategy creation and implementation. This study analyses the strategic structures and implementation of triple helix collaboration in two regional cases: Brainport (Netherlands) and Oulu innovation alliance (OIA, Finland). Case Brainport introduces a holistic approach and high profile role in regional development, whereas case OIA demonstrates the knowledge institutes' role in regional development in five spearhead areas. The cases illustrate two empirical ways to utilise triple helix mandate and strategic structures in regional development and strategy processes. The case comparison demonstrates diverse options for organising triple helix collaboration.
Undocumented migrants have diverse health problems.

INTRODUCTION In 2008, 1.9-3.8 million undocumented migrants lived in Europe. We aimed to strengthen the evidence base on undocumented migrants' health problems by describing characteristics of undocumented migrant patients in a Danish non-governmental organisation (NGO) health clinic. MATERIAL AND METHODS All patient files from the period from 24 August 2011 to 28 January 2013 were included in the study. Patient contacts were systematically analysed for age, sex, country of origin, medical referrals, symptoms and diagnoses. Contacts were classified by patient complaints or symptoms based on the International Classification of Primary Care, 2nd Edition (ICPC-2). RESULTS A total of 830 patients (39.75% women and 60.25% men) visited the clinic, which led to a total of 2,088 visits and 1,384 ICPC-2 classifications. The patients seen had 94 different nationalities. The most common reasons for medical contact correspond well with the pattern seen in general practice and several chronic and severe cases were observed in the NGO clinic. Furthermore, a larger share of pregnant women presented (11.6%) compared with a Danish general practice (5.1%), and these were seen first in a late gestational age on average (16+ weeks). CONCLUSION Undocumented migrants presented with diverse health problems. Some patients presented with critical disease, and an alarming number of pregnant women did not seek medical care until a late stage, and they did not return for infant care after giving birth. FUNDING The study was funded by the Institute of Public Health, University of Copenhagen. TRIAL REGISTRATION not relevant.
Role of Algorithmic and Co-Location Trading on the Speed of Information Adjustments: Evidence from India

ABSTRACT We investigate whether increased Algorithmic Trading (AT) intensity caused by the introduction of Co-location trading (CLT) facilities improve the productive efficiency of the Indian stock indices. We measure the change in the speed of information adjustment and change of persistence before and after the introduction of CLT for Indian Indices. We report an improvement in the overall productive efficiency of the leading Indian Indices, Midcap and Smallcap indices being the prominent beneficiaries. Our work contributes to the empirical literature on the ongoing debate on the benefits of AT and its role in improving market efficiency, especially in the emerging markets context.
The empirical validation of the sport brand love model in professional sports

Love is the highest form of attachment (Bowlby, 1979; Sternberg, 1987; Thompson, MacInnis, & Park, 2005) that consumers have towards brands, and it is integral to the success of organizations today. Sports boast of millions of raving consumers and may be one of the industries in which brand love is most evident; however, the multiple general marketing studies that were conducted on the brand love of traditional products (Albert, Merunka, & Valette-Florence, 2008; Batra, Ahuvia, & Bagozzi, 2012; Carroll & Ahuvia, 2006) were not directly applicable to sport. Therefore, the purpose of the study was to empirically validate the sport brand love model to allow sport managers a better understanding of sport brand love. Using consumers from the major professional sport teams in a large metropolitan area of the U.S., participants (N = 635) were surveyed using the sport brand love questionnaire developed in this study. The sample was split into two independent samples so the results could be cross-validated. The measurement model of the calibration sample and holdout sample had reasonably good fit, reliability, and validity considering the complexity of the model, and the structural model of both samples also had reasonably good fit. While the path coefficients for the samples were different, the subsequent multi-sample path analysis of the three teams provided an explanation for these differences. In the NBA and NFL group, “Team Nostalgia” was the only statistically significant (p < .05) antecedent, and “Perceived High Quality,” “Team Uniqueness,” and “Team Nostalgia” were statistically significant (p < .05) antecedents for the MLB group. The six consequences of sport brand love were statistically significant (p < .05) for all teams. Furthermore, the multi-group path analysis on gender indicated that “Team Nostalgia” was the only antecedent that was statistically significant (p < .05) for the female group, and “Perceived High Quality,” “Team Uniqueness,” and “Team Nostalgia” were statistically significant (p < .05) for the male group. However, gender was not a significant moderating variable when the individual teams were examined. These results indicate that sport marketers must understand sport brand love and create strategic marketing plans according to the type of sport.
Contrasting shrub species respond to early summer temperatures leading to correspondence of shrub growth patterns

The Arctic-alpine biome is warming rapidly, resulting in a gradual replacement of low statured species by taller woody species in many tundra ecosystems. In northwest North America, the remotely sensed normalized difference vegetation index (NDVI), suggests an increase in productivity of the Arctic and alpine tundra and a decrease in productivity of boreal forests. However, the responses of contrasting shrub species growing at the same sites to climate drivers remain largely unexplored. Here, we test growth, climate, and NDVI relationships of two contrasting species: the expanding tall deciduous shrub Salix pulchra and the circumarctic evergreen dwarf shrub Cassiope tetragona from an alpine tundra site in the Pika valley in the Kluane Region, southwest Yukon Territories, Canada. We found that annual growth variability of both species at this site is strongly driven by early summer temperatures, despite their contrasting traits and habitats. Shrub growth chronologies for both species were correlated with the regional climate signal and showed spatial correspondence with interannual variation in NDVI in surrounding alpine and Arctic regions. Our results suggest that early summer warming represents a common driver of vegetation change for contrasting shrub species growing in different habitats in the same alpine environments.
The role of peptide YY in appetite regulation and obesity

The last decade has witnessed a marked increase in our understanding of the importance of gut hormones in the regulation of energy homeostasis. In particular, the discovery that the gut hormone peptide YY 3–36 (PYY3–36) reduced feeding in obese rodents and humans fuelled interest in the role of PYY3–36 in body weight regulation. Pharmacological and genetic approaches have revealed that the Y2‐receptor mediates the anorectic effects of PYY3–36 whilst mechanistic studies in rodents identified the hypothalamus, vagus and brainstem regions as potential sites of action. More recently, using functional brain imaging techniques in humans, PYY3–36 was found to modulate neuronal activity within hypothalamic and brainstem, and brain regions involved in reward processing. Several lines of evidence suggest that low circulating PYY concentrations predispose towards the development and or maintenance of obesity. Subjects with reduced postprandial PYY release exhibit lower satiety and circulating PYY levels that correlate negatively with markers of adiposity. In addition, mice lacking PYY are hyperphagic and become obese. Conversely, chronic PYY3–36 administration to obese rodents reduces adiposity, and transgenic mice with increased circulating PYY are resistant to diet‐induced obesity. Moreover, there is emerging evidence that PYY3–36 may partly mediate the reduced appetite and weight loss benefits observed post‐gastric bypass surgery. Taken together these findings, coupled with the retained responsiveness of obese subjects to the effects of PYY3–36, suggest that targeting the PYY system may offer a therapeutic strategy to help treat obesity.
Recall of information received in hospital by female cardiac patients

Background The type and source of health information supplied to patients following cardiac events significantly improve adherence and health behaviours. The impact of health information upon female patients, however, is not well documented. This study investigates women's recall of the type and source of information provided to them in hospital about resuming daily activities after a cardiac event. It also identified women least likely to recall receiving information. Methods Interviews were conducted with female cardiac patients consecutively admitted to four metropolitan hospitals after acute myocardial infarction or for coronary artery bypass graft surgery. The women were interviewed on admission and at 2, 4 and 12 months after discharge. Participants were asked about in-hospital information provision at the 2-month interview (n = 224). Results Most women recalled receiving verbal information about medication, exercise and smoking cessation, but few recalled receiving verbal information about gardening, sexual activity, driving or sport. Women who were obese or physically inactive recalled limited advice about diet and physical activity, whereas women with diabetes or hypertension were no more likely than others to recall receiving information about medication, despite the personal relevance of this information. Older women were most at risk of recalling limited advice, including information about cardiac rehabilitation. Over half of the women attended a cardiac rehabilitation programme, with uptake being related to information provision. Conclusions The findings support other research suggesting that advice about activities after a cardiac event is inadequate for some women and confirms the influence of information provision on participation in cardiac rehabilitation.
Use of Intravenous Tranexamic Acid to Reduce Allogeneic Blood Transfusion in Total Hip and Knee Arthroplasty: A Meta-analysis

Total hip or knee arthroplasty is associated with significant blood loss. Techniques such as the use of antifibrinolytics or desmopressin, or normovolaemic haemodilution have been used to reduce the need for allogeneic blood transfusion. Tranexamic acid has been used to reduce blood loss and transfusion requirement for total hip and knee arthroplasty, with variable results. This meta-analysis aims to evaluate whether intravenous tranexamic acid, when compared with placebo, reduces blood loss and transfusion requirement in total hip and knee joint replacement surgery and whether it might increase the risk of thromboembolic complications. The literature search was based on MEDLINE, EMBASE, Cochrane Controlled Trials Register, and information from the pharmaceutical company that produces tranexamic acid (Pharmacia-Upjohn). We identified 15 clinical trials and 12 were considered suitable for detailed data extraction. Tranexamic acid reduces the proportion of patients requiring allogeneic blood transfusion (OR 0.16, 95% CI: 0.09–0.26), total amount of blood loss (WMD 460 ml, 95% CI: 274–626 ml), and the total number of units of allogeneic blood transfused (WMD 0.85 unit, 95% CI: 0.36–1.33). Tranexamic acid does not increase the risk of thromboemobolic complications such as deep vein thrombosis, pulmonary embolism, thrombotic cerebral vascular accident, or myocardial infarction (OR 0.98, 95% CI: 0.45–2.12). Intravenous tranexamic acid appears effective and safe in reducing allogeneic blood transfusion and blood loss in total hip and knee arthroplasty.
Cystic echinococcosis in Tunisia: analysis of hydatid cysts that have been surgically removed from patients

Abstract Echinococcosis/hydatidosis caused by Echinococcus granulosus has a widespread distribution in the human population of Tunisia, particularly in the north–west and centre–west of the country. In a recent study, the morphological features, fertility and viability of hydatid cysts that had been excised from patients in Tunis were explored, and the E. granulosus strain or genotype involved in each case was identified from morphology of the protoscolex hooks and the results of molecular genotyping. The hepatic cysts investigated came from 41 patients [31 women and 10 men, with a mean (S.E.) age of 43.41 (14.25) years] who were treated for cystic echinococcosis, by surgery but rarely with chemotherapy, at the La Rabta Hospital in Tunis, in the 12 months ending in June 2008. Most (56%) of these patients originated from rural areas in endemic governorates. Of the 60 hepatic cysts that were studied, 38.3% were located in the right lobe of the liver and 35.0% each involved both hepatic lobes. Almost a third (31.7%) of the excised cysts were degenerating, with the rest considered viable and either multivesicular (38.3%) or univesicular (30.0%). Almost all (93.3%) of the cysts were categorized as fertile, with a mean protoscolex viability of 21.8%. Protoscolex viability was relatively high in the viable univesicular cysts with a visible cyst wall and in the multivesicular and multiseptate cysts with daughter cysts, and lowest in the cysts that appeared to be solid calcified masses. The observed variation in protoscolex viability with cyst type, in cysts excised from patients before any chemotherapy, supports the cyst classification recommended by the World Health Organization but could also be compatible with the imaging-based 'Gharbi' classification. The results of the molecular genotyping showed that all 23 cysts investigated (which came from 20 of the patients) were caused by E. granulosus of the G1 genotype (also known as the 'sheep' or 'sheep–dog' strain).
ROLE OF SOCIAL MEDIA IN ELECTIONEERING: THE CASE OF THE NIGERIAN 2015 PRESIDENTIAL ELECTION

The 21st century can be described as the age of information technology. Technology runs almost all human endeavours, including politics. In recent times, politicians have swerved from the use of traditional media (broadcast and print) to the use of social media to carry out their political and electoral campaigns in order to realize their political ambition. One of the major challenges of electioneering in the 21st century is that, due to the faceless nature of the internet, social media spreads propaganda, false information, and hate speeches about an electoral candidate. These go viral and are used to manipulate the electorate. This paper examines the role of social media in the awareness, participation, and possible influence on the Nigerian electorate in their decision or choice of leadership during the 2015 presidential election. Findings show that the social media played a major role in mobilizing people, creating awareness, as well as participation and circulation of information about candidates. It therefore recommends, among other things, that regulatory methods on what should and should not be posted on social media should be put in place by the governing bodies of various social media platforms. This will help to censor and check information that spread on social media platforms. This way, campaigns that use and encourage hate speeches or instill violence will not be posted or published. The method of analysis is descriptive and the data are largely drawn from secondary literature. Keywords: Electioneering, Election, Hate Speech, Social Media, False Information.
Electronic Health Record Analysis of the Primary Care of Adults with Intellectual and Other Developmental Disabilities.

BACKGROUND AND AIMS Adults with intellectual and other developmental disabilities (IDD) are at risk for sub-optimal primary health care. Electronic Health Record (EHR) analyses are an under-utilized resource for studying the health and primary care of this population. METHODS This was a case-control EHR analysis of adults with IDD provided primary care through the Cleveland Clinic between 2005 and 2008. The IDD cohort was identified by relevant ICD-9 codes in problem list and encounter diagnoses. A comparison cohort matched by age, sex, race, and insurance was also specified. Demographic, health and health service characteristics of the two cohorts were compared. FINDINGS The IDD cohort consisted of 1267 individuals, mean age 39 years, 54% male, 78% Caucasian. Age, sex, racial, and health insurance characteristics were similar in the 2534 individuals in the comparison cohort. Individuals with IDD were significantly more likely to carry diagnoses of epilepsy, constipation, osteoporosis, obesity, and hyperlipidemia; but were significantly less likely to bear diagnoses of hypertension, diabetes, osteoarthritis, heart failure, coronary heart disease, and COPD. Despite a lower mean BMI, individuals with IDD were more likely to be labeled obese. Only genetic consultation rates were higher in the IDD cohort. DISCUSSION Health services research related to persons with IDD is becoming more feasible as large health systems adopt EHRs. Further analyses from this dataset will investigate whether variations in disease rates in adults with IDD represent true differences in disease prevalence versus disparities in health care.
US Monetary Policy and the Euro Area

This study documents empirically that contractionary US monetary policy may generate short-term expansionary spillover effects. In individual Euro Area (EA) member countries, economic activity increases, mainly via the trade channel. Also, domestic credit and stock markets expand, highlighting the importance of the financial channel. However, the international repercussions are transitory and distributed unevenly within the EA. The effect diminishes as EA interest rates increase with a few quarters delay. While the effects are heterogenous and rather large before 1999, responses become more homogeneous and smaller in size after the implementation of the euro. Still, country-specific asymmetries remain.
