Coach-Initiated Motivational Climate and Cohesion in Youth Sport

Purpose: The general purpose of the present study was to examine the link between cohesion and motivational climate in youth sport. The first specific objective was to determine if relationships demonstrated in previous research with adult basketball and handball participants would be replicated in a younger sample and with a more heterogeneous set of sports. The second specific objective was to examine whether sources of athlete enjoyment moderate the relationships between motivational climate and cohesion. Method: Athletes (N = 997; 532 girls and 465 boys; M age = 15.26 ± 1.20 years) completed measures pertaining to coach-initiated motivational climate, cohesion, and sources of enjoyment. Results: Bivariate and canonical correlations revealed positive correlations between perceptions of a task-involving motivational climate and both task and social cohesion, while ego-involving motivational climate was negatively related. Cluster analyses suggested that individuals perceiving a low task-involving climate and high ego-involving climate perceived their teams as less cohesive. Finally, the degree to which participants derived enjoyment through other-referenced competency served as a moderator in the motivational climate–task cohesion relationship. Specifically, the relationship between task cohesion and motivational climate was more pronounced for those individuals who were less likely to derive enjoyment through other-referenced competency. Conclusions: Youth athletes' perceptions of coach-initiated motivational climate are related to cohesion. This relationship is, however, moderated by the degree to which athletes derive enjoyment through other-referenced competency. Motivational climate is an important variable to consider within team-building protocols intent on developing cohesion.
A Time for Interdisciplinarity - An Essay on the Added Value of Collaboration for Science, University, and Society

The essay, written on the occasion of Tilburg University's Dies Natalis 2018, explores the added value of interdisciplinary collaboration for science, university, and society. It argues that interdisciplinary collaboration is a prerequisite for science to contribute to major problems – wicked problems – and thus generate impact of knowledge. Starting from that premise, the essay looks first at what exactly is interdisciplinarity (how does it distinguish itself from other forms of collaboration that transcend disciplines? ) and how it has evolved over time in the practice of science. It subsequently assesses whether there is a case for further strengthening and stimulating interdisciplinarity in research and education at (European) universities, and if so, how this could be organized. It closes with the observation that the design, organization, and outcome of interdisciplinary research and education need time, and hence, formulates a request towards universities to give their researchers and lecturers such "Time for Interdisciplinarity".
Intergenerational Occupational Mobility in a Rural Economy

This paper presents evidence on intergenerational occupational mobility from agriculture to the nonfarm sector using survey data from Nepal. In the absence of credible instruments, the degree of selection on observables is used as a guide to the degree of selection on unobservables a la Altonji et. al. (2005) to address the unobserved genetic correlations relevant for occupation choice. The results show that a moderate ability correlation can easily explain away the observed partial correlation in non-farm participation between the father and a son. In contrast, the partial correlation in occupation choice between mother and daughter is much stronger, and is unlikely to be driven by genetic correlations alone. The results suggest that mother's nonfarm participation plays a causal role in daughter's choice of nonfarm occupation, possibly because of cultural inheritance through role model and learning effects, and transfer of reputation and social capital.
Weed Seed Survival in Livestock Systems 9 2 05.pub

Jerry Doll University of Wisconsin 608.263. 7437 jddoll@wisc.edu Introduction. Manure is an important soil amendment. In addition to providing valuable nutrients, manure enriches the microbial population and diversity and adds organic matter to the soil. However, many assume manure is always rich in weed seeds. The opposite is probably the case as most of our harvested forage is relatively free of weed seeds. Exceptions obviously exist. There is no simple method to extract weed seeds from feed or manure and to then test them for viability. So the best advice is to understand current knowledge about weed seeds in manure and how they may impact your operation. Key factors that determine the potential for weed seed problems from livestock systems are feed sources, type of animals, and type of feed and manure handling systems.
Rapid Profiling of the Antigen Regions Recognized by Serum Antibodies Using Massively Parallel Sequencing of Antigen-Specific Libraries

There is a need for techniques capable of identifying the antigenic epitopes targeted by polyclonal antibody responses during deliberate or natural immunization. Although successful, traditional phage library screening is laborious and can map only some of the epitopes. To accelerate and improve epitope identification, we have employed massive sequencing of phage-displayed antigen-specific libraries using the Illumina MiSeq platform. This enabled us to precisely identify the regions of a model antigen, the meningococcal NadA virulence factor, targeted by serum antibodies in vaccinated individuals and to rank hundreds of antigenic fragments according to their immunoreactivity. We found that next generation sequencing can significantly empower the analysis of antigen-specific libraries by allowing simultaneous processing of dozens of library/serum combinations in less than two days, including the time required for antibody-mediated library selection. Moreover, compared with traditional plaque picking, the new technology (named Phage-based Representation OF Immuno-Ligand Epitope Repertoire or PROFILER) provides superior resolution in epitope identification. PROFILER seems ideally suited to streamline and guide rational antigen design, adjuvant selection, and quality control of newly produced vaccines. Furthermore, this method is also susceptible to find important applications in other fields covered by traditional quantitative serology.
The physics of kHz QPOs---strong gravity's coupled anharmonic oscillators

We explain the origin of the puzzling high frequency peaks (QPOs) in the variability power spectra of accreting neutron stars and black holes as a non-linear 1:2 or 1:3 resonance between orbital and radial epicyclic motion. These resonances are present because the gravitational field deviates strongly from a Newtonian 1/r potential. Our theory agrees with the recently reported observations of two QPOs, at 300 Hz and 450 Hz, in the black hole candidate GRO J1655-40.
Radionuclide Hepatobiliary Imaging in Evaluation of Reserved Hepatic Function in Patients with Hepatocelluar Carcinoma before Transcatheter Arterial Embolization

Background: Hepatocellular carcinoma(HCC)is a common cancer in Asia. Transcatheter arterial embolization(TAE)is the most common modality to treat unresectable HCC but is contraindicated inpatients with insufficient hepatic reserve. The purpose of this study is to use radionuclide hepatobiliary imaging (RHI)to evaluate the reserved hepatic function inpatients with HCC before TAE. Methods: Eighty-two patients(male: female=63:19;age range:23～72 y/o,mean:49.6 y/o)with HCC were included in this study. All of the patients underwent conventional hepatic function tests(HFT),and indocyanine green(ICG)test. RHI was done within 2 days after HFT and ICG test. RHI was performed dynamically after bolus injection of 6 mCi of 99mTc-diisopropyl iminodiacetate (DISIDA)with 60 sec per frame for 60 min. Hepatic extraction fraction(HEF),excretion half-time(T(subscript 1/2))and peak-time of uptake(PTU)were calculated. The correlations between HEF,T(subscript 1/2),PTU and HFT, ICGtest were studied. Results: There was significant correlation between HEF and Bil, AST,ALT, albumin, Alk-P,PT and ICG test(P＜0.05). There was significant correlation between PTU and Bil, Alk-P and ICG test(P＜0.05). There was also significant correlation between T(subscript 1/2)and Bil, Alk-Pand ICG test(P＜0.05). Discrepancies between HFT and ICG test occurred in 8 patients; however, the values of HEF in these 8 patients correlate well with HFT. Conclusion: RHI could be used as a final arbitration when discrepancy between traditional HFT occurs. HEF could be a single indicator for reserved hepatic function.
Prognostic factors associated with the success rates of posterior orthodontic miniscrew implants: A subgroup meta-analysis

Objective To systematically review previous studies and to assess, via a subgroup meta-analysis, the combined odds ratio (OR) of prognostic factors affecting the success of miniscrew implants (MIs) inserted into the buccal posterior region. Methods Three electronic searches that were limited to articles on clinical human studies using MIs that were published in English prior to March 2015 were conducted. The outcome measure was the success of MIs. Patient factors included age, sex, and jaw of insertion (maxilla vs. mandible), while the MI factors included length and diameter. A meta-analysis was performed on 17 individual studies. The quality of each study was assessed for non-randomized studies and quantified using the Newcastle-Ottawa Scale. The meta-analysis outcome was a combined OR. Subgroup and sensitivity analyses based on the study design, study quality, and sample size of miniscrews implanted were performed. Results Significantly higher success rates were revealed for MIs inserted in the maxilla, for patients ≥ 20 years of age, and for long MIs (≥ 8 mm) and MIs with a large diameter (> 1.4 mm). All subgroups acquired homogeneity, and the combined OR of the prospective studies (OR, 3.67; 95% confidence interval [CI], 2.10-6.44) was significantly higher in the maxilla than that in the retrospective studies (OR, 2.10; 95% CI, 1.60-2.74). Conclusions When a treatment plan is made, these risk factors, i.e. jaw of insertion, age, MI length, and MI diameter, should be taken into account, while sex is not critical to the success of MIs.
Channel diffusion of sodium in a silicate glass

We use classical molecular dynamics simulations to study the dynamics of sodium atoms in amorphous ${\mathrm{Na}}_{2}\mathrm{O}\ensuremath{-}4{\mathrm{SiO}}_{2}. $ We find that the sodium trajectories form a well connected network of pockets and channels. Inside these channels the motion of the atoms is not cooperative, but rather is given by independent thermally activated hops of individual atoms between the pockets. By determining the probability that an atom returns to a given starting site, we show that such events are not important to the dynamics of this system at high temperatures.
Hyperbolicity and Invariant Manifolds for Planar nonautonomous Systems on Finite Time Intervals

The method of invariant manifolds was originally developed for hyperbolic rest points of autonomous equations. It was then extended from fixed points to arbitrary solutions and from autonomous equations to nonautonomous dynamical systems by either the Lyapunov–Perron approach or Hadamard's graph transformation. We go one step further and study meaningful notions of hyperbolicity and stable and unstable manifolds for equations which are defined or known only for a finite time, together with matching notions of attraction and repulsion. As a consequence, hyperbolicity and invariant manifolds will describe the dynamics on the finite time interval. We prove an analog of the Theorem of Linearized Asymptotic Stability on finite time intervals, generalize the Okubo–Weiss criterion from fluid dynamics and prove a theorem on the location of periodic orbits. Several examples are treated, including a double gyre flow and symmetric vortex merger.
Patch-based Laplacian filter based transmission estimation for single image dehazing

Transmission estimation is the primary task for single image haze removal. In this paper, we proposed a more accurate transmission estimation method for image haze removal based on any transmission extraction prior (eg., dark channel prior, color line prior). Firstly, we generate raw transmission in Gaussian pyramid using any transmission extraction prior. Secondly, a patch-based Laplacian pyramid is built from the nonlinear remapped function point by point. Thirdly, we obtain the global Laplacian map with patch-based remapped image and use them to guide the transmission refinement. Finally, the dehazing result is restored from the refined transmission and atmospheric scattering model. Experiments show that the proposed method achieves higher quality of halo-free and detail restoration performance than the existing dehazing methods.
Joining Movement Sequences: Modified Dynamic Movement Primitives for Robotics Applications Exemplified on Handwriting

The generation of complex movement patterns, in particular, in cases where one needs to smoothly and accurately join trajectories in a dynamic way, is an important problem in robotics. This paper presents a novel joining method that is based on the modification of the original dynamic movement primitive formulation. The new method can reproduce the target trajectory with high accuracy regarding both the position and the velocity profile and produces smooth and natural transitions in position space, as well as in velocity space. The properties of the method are demonstrated by its application to simulated handwriting generation, which are also shown on a robot, where an adaptive algorithm is used to learn trajectories from human demonstration. These results demonstrate that the new method is a feasible alternative for joining of movement sequences, which has a high potential for all robotics applications where trajectory joining is required.
Immediate interviewing increases children's suggestibility in the short term, but not in the long term

Purpose Children sometimes receive misinformation after being formally interviewed about their experiences in cases of suspected abuse. Following decades of research, many guidelines have been produced for interviewers so they can obtain reliable statements in children, like, for example, the NICHD protocol. One might expect that completing an early interview following research‐based guidelines might guard against the incorporation of misinformation encountered later. The goal of the current experiments was to examine whether following research‐based guidelines such as the NICHD protocol might protect child witnesses against follow‐up ‘misinformation’ or make them more vulnerable to misinformation. This increased vulnerability to misinformation has been referred to as retrieval‐enhanced suggestibility. Methods In two experiments, children viewed a video and half of them were interviewed using the NICHD protocol, while the other half were not interviewed. The children received misinformation and a final memory test either immediately after being interviewed (Experiment 1) or 1 week later (Experiment 2). Results Retrieval‐enhanced suggestibility was observed when misinformation was presented immediately but not when it was provided after 1 week. Conclusions The current experiments indicate that a well‐established interview protocol can, under some circumstances, amplify levels of suggestibility in children.
Radiofrequency-targeted vertebral augmentation versus traditional balloon kyphoplasty: radiographic and morphologic outcomes of an ex vivo biomechanical pilot study

Purpose Traditional balloon kyphoplasty (BK) is a common treatment for symptomatic vertebral compression fractures. The purpose of this study was to compare a novel vertebral augmentation technique, radiofrequency-targeted vertebral augmentation (RF-TVA), to BK for restoration of vertebral height, cavity creation, and polymethylmethacrylate (PMMA) delivery and interdigitation into the surrounding trabeculae. Methods This ex vivo biomechanical pilot study utilized 16 osteoporotic cadaveric vertebral bodies in a standardized fracture model to compare unipedicular RF-TVA (n = 8) to bipedicular BK (n = 8). Four specimens from each group were tested in loaded and unloaded conditions. All specimens were imaged, assessed for height restoration, and sectioned to observe PMMA distribution. A subset of specimens underwent computed tomography scanning to assess cavity creation and trabecular architecture prior to cement delivery. Results Anterior height restoration was greater with RF-TVA (median: 84%, interquartile range: 62%–95%) compared to BK (median: 69%, interquartile range: 60%–81%), although the difference did not achieve statistical significance (P = 0.16). Anterior height restoration was numerically greater under loaded (median: 70% versus 66%) and unloaded (median: 94% versus 77%) conditions with RF-TVA versus BK. RF-TVA produced more discrete cavities and less native trabecular destruction compared to marked trabecular destruction observed with BK. RF-TVA consistently showed a well-identified focal area of PMMA with an extensive peripheral zone of PMMA interdigitation, providing mechanical interlock into the adjacent intact trabecular matrix. In contrast, BK yielded little evidence of PMMA interdigitation beyond the boundaries created by the balloon tamp due to the crushed trabecular bone peripherally. Conclusion RF-TVA achieves favorable vertebral height restoration with targeted PMMA delivery and less trabecular destruction compared to BK. RF-TVA has potential clinical utility in the aging population with painful osteoporotic vertebral fracture.
Effects of Elevated Temperature and Carbon Dioxide on the Growth and Survival of Larvae and Juveniles of Three Species of Northwest Atlantic Bivalves

Rising CO2 concentrations and water temperatures this century are likely to have transformative effects on many coastal marine organisms. Here, we compared the responses of two life history stages (larval, juvenile) of three species of calcifying bivalves (Mercenaria mercenaria, Crassostrea virginica, and Argopecten irradians) to temperatures (24 and 28°C) and CO2 concentrations (∼250, 390, and 750 ppm) representative of past, present, and future summer conditions in temperate estuaries. Results demonstrated that increases in temperature and CO2 each significantly depressed survival, development, growth, and lipid synthesis of M. mercenaria and A. irradians larvae and that the effects were additive. Juvenile M. mercenaria and A. irradians were negatively impacted by higher temperatures while C. virginica juveniles were not. C. virginica and A. irradians juveniles were negatively affected by higher CO2 concentrations, while M. mercenaria was not. Larvae were substantially more vulnerable to elevated CO2 than juvenile stages. These findings suggest that current and future increases in temperature and CO2 are likely to have negative consequences for coastal bivalve populations.
Differences in Handedness and Scores of Aggressiveness and Interpersonal Relations of Soccer Players

Handedness and differences in interpersonal relations and aggressiveness were studied in 33 right-handed (M age = 22.9 yr., SD = 4.9) and 18 left-handed (M age = 22.5 yr., SD = 2.4) male soccer players who played actively in professional soccer leagues of Turkey. Hand preference on the Edinburgh Handedness Inventory and scores for destructiveness, assertiveness, and passive aggressiveness on a Turkish Aggressiveness Inventory, plus scores for sociability, benevolence, tenderheartedness, tolerance, and insistence on the Turkish Interpersonal Relations Inventory were examined. Mean destructive aggressiveness was higher for the left- than the right-handed athletes. Means on tolerance and insistence were higher for the right- than the left-handed athletes. Higher aggressiveness and less tolerance and insistence in the left-handers may be associated with their higher sports performance.
The association between social characteristics, alcoholic beverage preferences, and binge drinking in a Serbian adult population

Aim: To determine the association of sociodemographic characteristics and type of alcoholic beverage consumed during binge drinking in Serbia. Method: We conducted a secondary analysis of data from the 2014 national survey on Serbian lifestyles focusing on substance abuse and gambling. The sample consisted of 5385 individuals. The respondents were divided into non-binge drinkers and binge drinkers, according to the quantity of alcohol consumed during one occasion. Binge drinkers reported consuming more than 60 g of pure alcohol (7.5 units of alcohol) during one occasion at least once during the previous year. Results: The prevalence of binge drinking in the past year among 2676 female and 2709 male participants aged 18–64 years was 28.4%. The multivariate logistic regression model showed that binge drinkers were more likely to be male (95% CI 3.58–4.94), single (95% CI 1.01–1.53), to be former (95% CI 1.06–1.62) or current smokers (95% CI 1.57–2.19), and to consume more than one type of alcoholic beverage (95% CI 2.04–3.44). There was a negative association of binge drinking with age (95% CI 0.98–0.99), living outside Northern Serbia-Vojvodina region, and drinking only spirits (95% CI 0.39–0.93). Conclusion: Focusing on the positive association of sociodemographic factors and binge drinking could help policy makers create public health interventions against alcohol misuse. These interventions should be directed to males, smokers, and those who consume more than one type of alcoholic beverage.
The continuity and intensity of ultraviolet irradiation affect the kinetics of biosynthesis, accumulation, and conversion of mycosporine‐like amino acids (MAAs) in the coral Stylophora pistillata

Colonies of Stylophora pistillata unexposed to ultraviolet radiation (UVR) in laboratory aquaria contained minimal amounts of mycosporine‐like amino acids (MAAs). The concentration of MAAs increased rapidly during exposure to broadband UVR, then stabilized between 14 and 28 d of exposure. The four MAAs known to be produced by diverse zooxanthellae (Symbiodinium spp.) in culture were the first to increase in coral colonies, followed by six additional MAAs. Decreases in these four primary MAAs between days 14 and 28 were balanced by stoichiometric increases in the six secondary MAAs, suggesting a precursor‐product relationship. Discontinuing UV exposure caused rapid declines in the concentrations of primary MAAs, while secondary MAAs continued to increase, likely a manifestation of different rates of turnover of the putative enzymes involved in the de novo biosynthesis of primary MAAs and their conversion to secondary MAAs. The continued production of certain MAAs after UV exposure ceased indicates that UV is not required catalytically but is a signal that induces the enzymes of the biosynthetic pathway. Biochemically inhibiting the biosynthesis of primary MAAs after a pool of these MAAs had accumulated did not affect their conversion to secondary MAAs. Doubling the UV irradiance increased the rate of accumulation, first, of primary MAAs and, later, of secondary MAAs. Under normal UV irradiance, the eventual decline in the accumulation rate of primary MAAs was quantitatively explained by their conversion to secondary MAAs. Under doubled UV irradiance, where MAA concentrations were higher, the deceleration of accumulation of primary MAAs was twice as great as the acceleration in secondary MAAs, suggesting a regulation of the de novo biosynthesis of MAAs, perhaps by their own progressive, concentration‐dependent attenuation of UVR.
