Mental health, eating behaviour and injuries in professional dance students

ABSTRACT A high frequency of mental health challenges and injuries in professional dancers necessitate a better understanding of the complexity of such symptoms, and to explore differences according to sex, academic year and performance levels. Professional dance students were recruited to evaluate symptoms of depression and anxiety (SCL-10), resilience (RSA), self-esteem (RSS), perfectionism (CAPS), body appreciation (BAS-2), and symptoms of low energy availability (LEA, LEAF-q) and eating disorders (ED) (EDE-q). Totally 20–54% of the dancers had symptoms of anxiety or depression, LEA (in females), ED and/or injuries, and 12% had a self-reported history with ED. In females, 44% of the variability in SCL-10 was explained by CAPS and RSS; 15% of variability in LEA was explained by EDE-q and training volume; while BMI, academic year and LEA increased the odds ratio of an injury. In all, BAS-2 reduced the odds ratio of EDE-q by -3.33. Totally 50% reported that they could identify personal mental health problems, still <45% would consult a health professional. Enhanced body acceptance may reduce the frequency of mental health challenges in dancers, and improved knowledge of nutrition and body weight regulation may reduce the high frequency of LEA, disordered eating behaviour, and injuries.
Prediction of the Flashover Performance of Ice-Covered Insulators

In this paper, the mathematical model for predicting the critical flashover voltage of ice-covered insulators is presented. It is applied to different insulators covered with ice and then the results are validated with experimental results obtained for various insulators in laboratories. Based on these results, the effects of insulator parameters, including the insulator type, length, and diameter, on the flashover performance of ice-covered insulators are determined and analyzed. The results will be helpful for properly selecting the parameters of insulators used in cold climate regions.
How does radical's positional consistency affect the performance of recognition of pseudo-characters across primary grades?

A pseudo-character recognition task was conducted to investigate the influence of positional consistency of radicals on reading Chinese characters across grades. Pseudo-characters were constructed horizontally in four conditions: HH, high radical’s positional consistency on both left and right; HL, high radical’s positional consistency on left but low on right; LH, low radical’s positional consistency on left but high on right; and LL, low radical’s positional consistency on both left and right. The results showed different performance towards different conditions suggesting the importance of positional information in sub-lexical processing of Chinese characters. In addition, a superior performance in recognizing LL characters by the first and third graders suggested an immature ability in recognizing radicals as a free agent while a superior performance in recognizing LL characters by the fifth graders revealed the maturation of this ability and the development of new skill in lexical-processing. When radicals were successfully recognized as a free agent that could be traveled freely within a character, high positional consistency facilitated reading while low positional consistency inhibited.
An investigation of occupational accidents and safety risks in policing: Views of employees

Policing is one of the riskiest and dangerous professions by its nature. Police officers face a range of risks at work: homicide, assaults, attacks, communicable diseases, car crashes or explosions. The risks vary according to the task being undertaken such as arresting offenders, attending street disturbances or performing traffic duties. These risks, having the characteristics of occupational accident in a way, have institutional losses like compensation, loss of manpower and reputation besides individual results like injury, death, mutilation, and posttraumatic stress disorder, exposure to psychological disorders or decrease in quality of life. Opinions and suggestions of 1066 employees currently working at different ranks and units in Turkish National Police in regards with reducing the risks of occupational accidents and safety risks were studied in this research. Suggestions of the participants were reviewed under total nine headings (themes) consisting of training, physical fitness and health, security measures, institutional policies and procedures, managerial policies, working conditions, equipment, uniforms, and patrol cars.

VU Research Portal Gross Efficiency in Cyclic Sports

Speed skating posture, or technique, is characterized by the push-off angle or effectiveness ( e ), determined as the angle between the push-off leg and the ice; the preextension knee angle ( θ 0 ); and the trunk angle ( θ 1 ). Together with muscle-power output and environmental conditions, skating posture, or technique, determines velocity ( v ). Purpose : To gain insight into technical variables that are important to skate efficiently and perform well, e , θ 0 , θ 1 , and skating v were determined every lap during a 5000-m World Cup. Second, the authors evaluated if changes ( Δ ) in e , θ 0 , and θ 1 are associated with Δ v . Methods : One camera filmed the skaters from a frontal view, from which e was determined. Another camera filmed the skaters from a sagittal view, from which θ 0 and θ 1 were determined. Radio-frequency identification tags around the ankles of the skaters measured v . Results : During the race, e progressively increased and v progressively decreased, while θ 0 and θ 1 showed a less consistent pattern of change. Generalized estimating equations showed that Δ e is significantly associated with Δ v over the midsection of the race ( β = –0.10, P < .001) and that Δθ 0 and Δθ 1 are not significantly associated with Δ v . Conclusions : The decrease in skating v over the race is not due to increases in power losses to air friction, as knee and trunk angle were not significantly associated with changes in velocity. The decrease in velocity can be partly ascribed to the decrease in effectiveness, which reflects a decrease in power production associated with fatigue.
Technological Innovation And The Performance Of Food And Beverage Manufacturing Companies

Innovation is a strategy that leads to gaining competitive advantage in the marketplace. It makes business organisations sustainable and enables them to be in positions to adequately meet the needs of their customers in the face of changing tastes and fashion. So, organisations that have poor attitudes towards innovation that consequently result in low ability to create products and services that satisfy their customers decrease their chances of growth and survival in the marketplace. The objective of this study was to investigate the effect of technological innovation on the performance of food and beverage manufacturing companies in Osun state, Nigeria. Specifically, the effect of product and process innovations on company performance was investigated. This study was conducted based on survey research design. Data collected for the study on a five-point Likert scale ranging for Strongly Agree 5 to Strongly Disagree 1 were analysed based on descriptive and inferential statistics. Multiple regression analysis provide measures for the effect of the constructs on company performance. The results of multiple regression analysis indicated statistical significance for the hypotheses of the study. Technological innovation had positive effect on performance. Technological innovation explained 68.59 percent variation in company performance. The two components of technological innovation, product innovation and process innovation that were tested for statistical significance indicated positive effects on performance. Having ascertained positive effect of technological innovation on company performance, the study emphasized the need for the companies to place greater reliance on it to increase the chances of explaining more variation in performance and improving their competitive positions in the marketplace.
Soil physical properties, nutrients, and crop yield with two-year tillage rotations under a winter wheat-summer maize double cropping system

: Winter wheat and summer maize were planted from 2015-2017 to study the effects of different rotational tillage patterns on soil physicochemical properties, crop yield, water content, and fertilizer utilization. The tillage treatments were designed as wheat subsoiling-maize no tillage (WS-MN), wheat rotary tillage-maize subsoiling (WR-MS), wheat subsoiling-maize subsoiling (WS-MS), and conventional wheat rotary tillage-maize no tillage (WR-MN) as a control. Among the four treatments, WS-MN and WR-MS were single-season subsoiling treatments, and WS-MS was a two-season subsoiling treatment. The average soil bulk density decreased by 7.6% in the single- and double-season subsoiling groups compared to the WR-MN group, and the total porosity and noncapillary porosity increased by 10.7% and 12.2%, respectively. Single- or double-season subsoiling treatment was not conducive to water storage in the 0-20 cm soil layer but increased the water content of the 20-140 cm soil layer, and the average soil water content of the 0-140 cm layer was increased by 11.6% in the two-growing season treatment groups compared with the WR-MN group. In WS-MS and WS-MN groups compared with the WR-MN group, the soil ammonium nitrogen content was increased by an average of 18.6% in 0-20 cm soil and 16.8% in 20-100 cm soil; soil nitrate-nitrogen content was decreased by 13.5% in 0-100 cm soil; total organic carbon and microbial carbon contents in the 15-30 cm soil were increased by 18.1% and 12.7%, respectively; and soil urease, catalase, and alkaline phosphatase activities were increased by 46.1%, 15.2%, and 23.1%, respectively. Annual crop yield and water use efficiency increased by 8.9% and 15.0%, respectively, in both the single- and double-season subsoiling treatment groups. This study demonstrated the advantages of subsoiling tillage and suggested that it is suitable for crop cultivation in the Haihe Plain, China. and crop yield with two-year under a cropping
Housing Loan Repayment Behaviour in Malaysia: An Analytical Insight

The present study aims to decipher the drivers of default status (no default, single default, double default, and default to good) of 43,156 home-loan borrowers of a large home-loan lender having a national presence during 2003-18. Using the Multinomial Logit model, we analyse the repayment behaviour controlling the borrowers' loan and socio-demographic characteristics. We find house equity, loan, and borrower characteristics, and ability to pay are the key determinants. We also find that both double default and first default are higher at lower growth rates of house prices. Non-linearity and the inflection points in the profile of age, loan age, loan term, payment to income ratio, loan to value ratio, and loan interest rates vis-a-vis loan default status are significant findings. Tapering-off of default due to seasoning beyond a threshold year is notable. The study is the first of its kind, which uses granular data in its analysis, and hence the results would prove immensely beneficial in the policy formulations and managerial decisions.
Irrigation and fertilization of Chrysothamnus nauseosus (Asteraceae) affect the attack and gall growth of Rhopalomyia chrysothamni (Cecidomyiidae)

The quality of the environment and the host plant influence the development of the galls as well as the performance of gall inducing insects. The effect of nutrients and water availability on the development of galls induced by Rhopalomyia chrysothamni (Diptera: Cecidomyiidae) on Chrysothamnus nauseosus subsp. hololeucus (Asteraceae) was tested. The study was conducted in a xeric area with no signs of disturbances in Coconino National Forest, Arizona, USA. Individuals of C. nauseosus randomly selected underwent three treatments of water and nutrients availability. At the end of the growing season, the number of attacked plants, abundance and the development of galls in each treatment were evaluated. The differences in habitat quality simulated by the fertility and humidity conditions influenced both the number of attacked plants and the growth of galls. Plants with lower hydric-nutritional quality were more attacked by the galling insect. Otherwise, when both water and nutritional stresses were relieved plants developed galls with higher dry biomass and density. Therefore, this field experimental study indicates that while galling females attacked plants more in xeric environments, the galls grew larger in relatively more mesic conditions. The results showed a trade-off between the quantity and quality of galls of R. chrysothamni depending on the nutritional quality of the host plants.
The Diel Cycle of Surface Ocean Elemental Stoichiometry has Implications for Ocean Productivity

Environmentally driven variability in the elemental stoichiometry of ocean plankton plays a key role in ocean biogeochemical processes. Recent studies have identified clear regional variability in C:N:P, but less is known about the environmental regulation of diel variability in plankton elemental stoichiometry. Here, we quantified the amplitude of the diel variability in C:N of surface ocean particles (<30 μm, C:Namp) across large latitudinal gradients in the Indian and Atlantic Oceans. We commonly observed diel oscillations in C:N and biome‐specific variability in C:Namp. Temperature emerged as the strongest predictor of C:Namp, relative to the supply of nitrate. We propose that C:Namp is positively related to photosynthesis and respiration and thus phytoplankton growth rates. We find that independent growth rate proxies and an ecosystem model support this hypothesis. In addition, the temperature sensitivity of C:Namp has a Q10 of 1.78 corroborating studies of phytoplankton growth rates. Surface communities across the Indian Ocean transect had a very small dependency on nitrate, whereas recycled nitrogen sources were by far the most preferred and the ratio of recycled‐N:nitrate utilization increased with increasing C:Namp. To predict future changes in C:Namp, we combined our statistical model with data from the fifth Coupled Model Intercomparison Project for the years 1990 and 2090. The results suggest that future rising temperatures will yield increased C:Namp. Collectively, our results imply that rising surface ocean temperatures lead to elevated phytoplankton growth rates supported by recycled nutrients.
Experiments on Liquid Surface Deformation Upon Impingement by a Gas Jet

The impingement of a gas jet on a liquid surface has several applications including electric arc furnace steel-making, top blown copper converting, welding and dust removal from the producer gas obtained from biomass gasification. An experimental model has been developed to study the effect of a circular air jet impinging upon a liquid surface. Experiments are conducted with variations in the type of liquid, jet velocity, and separation distance between the nozzle and the liquid surface. Upon jet impingement a cavity (depression) is created on the surface of the liquid. The width and height of this cavity have been determined using sophisticated image processing and edge detection software. The shape of the cavity is either parabolic or Gaussian depending on the conditions of the jet flow and the liquid bath. The shear of the impinging air jet causes recirculatory flow patterns within the liquid that are visualized using aluminum particles as tracers. The measurements show that the previously reported theoretical analysis cannot make accurate predictions of the width and height of the cavity unless surface tension and viscous effects of the liquid are properly accounted for.
The association between folic acid supplementation and congenital heart defects: Systematic review and meta-analysis

Introduction: Various trial and epidemiological studies consistently documented the association between maternal folic acid supplementations and neural tube defects. However, existing literatures revealed inconclusive findings about maternal periconceptional folic acid supplementations and the risk of congenital heart defects. Thus, the current systematic review and meta-analysis was aimed to estimate the pooled association between maternal periconceptional folic acid supplementations and congenital heart defects. Methods: Electronic searches of PubMed, Web of Science/Scopus, Cochrane library and Google Scholar databases were conducted to access the required studies published up to March 2021. Predetermined eligibility criteria were used for study selections. Data extraction were independently done on excel. STATA version 14 software was used to calculate the pooled effect size with 95% confidence intervals (95% CI) of maternal periconceptional folic acid supplementations on congenital heart defects using the DerSimonian and Laird random effects meta-analysis (random effects model). Statistical heterogeneity was checked using the Cochran Q test (chi-squared statistic), I2 statistic, and by visual inspection of the funnel plot. Results: A total of 37 studies of case–control, cohort and randomized controlled trial in nature were included in the review. The finding of the present systematic review and meta-analysis indicated that periconceptional folic acid supplementation significantly decreases the risk of congenital heart defects (risk ratio (RR), 0.79; CI, 0.71, 0.89). Both Cochrane Q test statistic (χ2 = 19.33, p = 0.962) and I2 test statistic (I2 = 0.0%, p = 0.962) did not reveal statistically significant heterogeneity among included studies. In this meta-analysis, traditional funnel plot, Begg’s funnel plot, Egger’s weighted regression (p = 0.13) as well as Begg’s rank correlation statistic (p = 0.676) revealed no evidence of publication bias. Conclusion: The present systematic review and meta-analysis found that maternal periconception folic acid supplementation was significantly associated with the risk of congenital heart defects. The risk of congenital heart defects was significantly reduced by 21% among those children of mothers who use periconceptional folic acid supplementations in high-income countries. We recommend that a large prospective study be conducted to investigate the association between maternal periconceptional folic acid supplementation and occurrence of congenital heart defect of various types, especially in the developing countries.
SEISMIC RESPONSE OF AN ARCH-BEAM INTERACTING WITH SEQUENTIAL MOVING TRAIN LOADS

Considering the axial-flexural coupling nature of an arch bridge subjected to seismic wave, this paper is aimed at investigation of dynamic response for a train moving over a railway arch-bridge shaken by horizontal ground motions. For analytical formulation, the arch bridge is idealized as a flat-rise parabolic arch with constant sectional properties uniformly distributed along the horizontal span and the train moving over it as a sequence of identical sprung mass units with constant intervals. To perform dynamic analysis of vehicle-bridge system shaken by horizontal earthquakes, an incremental-iterative procedure is proposed in this study. From numerical results, the multiple support motion induced by seismic wave propagation plays a key factor in affecting the dynamic response of the arch-bridge/vehicle system during earthquakes.
Management Strategy Evaluation for the Common Spiny Lobster, Palinurus elephas (Fabricius, 1787), Stock in Tunisia

The common spiny lobster, Palinurus elephas (Fabricius, 1787), fishery in Tunisia has been overexploited. This species is currently managed by temporal closures, minimum legal sizes of landings, and the prohibition of catching berried females. This study aims to develop management procedures (MPs) based on the surplus production model to set total allowable catch (TAC) as a management action for the common spiny lobster. Ten MPs ranging from conservative to more relaxed management procedures were evaluated within a management strategy evaluation (MSE) framework. Several scenarios of the operating model were considered to account for uncertainties. Five performance measures were used to evaluate MPs to identify the management strategies that can achieve the prespecified management objective of recovering the stock size as a priority and ensuring high and stable catches. The results of the MSE showed that the conservative management strategies with the highest control points performed well in terms of management objectives with a probability of biomass exceeding the reference point of higher than 90 % but yielded in the lowest catches. On the other hand, relaxed threshold-based management strategies failed in achieving management objectives with 20 % probability of being below the limit reference point. These MSE results also highlighted the trade-off between conservation and catch performance objectives and showed that some moderate management strategies balanced these objectives efficiently.
The beneficial effects of Ferula asafoetida oleo-gum resin in gastrointestinal disorders

Ferula asafoetida is a plant from Umbelliferae Family, which its gum is traditionally used to treat the gastrointestinal disorders (parasite, bloating, digestion, cancer). According to its traditional applications, the subject of this review was to evaluate the efficacy of F. asafoetida in management of different gastrointestinal disorders in modern medicine. For this purpose, the scientific resources (PubMed, Web of Science, Scopus, Google Scholar, SpringerLink, SciFinder, ACS Publications, and Wiley), traditional books, and thesis were investigated by the word of F. asafoetida, Hing, and gastrointestinal tract and the results were evaluated. There was one clinical trial on the efficacy of F. asafoetida in treatment of functional dyspepsia, and the other pharmacological activities such as anti-parasite, anti-cancer, antidiarrhea and liver protective effects were evaluated in preclinical studies. Although, F. asafoetida can be proposed as a good candidate for treatment of gastrointestinal disorders, but the majority of studies have been limited to the experimental investigations. Therefore, evaluation of its efficacy and safety in well-designed human clinical studies is required to use of this valuable oleo-gum resin.
T-lymphocytes Expression of Toll-like Receptors 2 and 4 in Acute Myeloid Leukemia Patients with Invasive Fungal Infections

Background Invasive fungal infections (IFIs) are important cause of mortality in acute myeloid leukemia (AML) patients on treatment with intensive induction chemotherapy. Toll-like receptors, mainly Toll-like receptors 2 and 4 (TLR2 and TLR4), play a considerable role in the host defense against microorganisms. The involvement of TLR signaling in modulation of innate immune response is extensively discussed, but the TLR expressions profiling on adaptive immune cells are not specified. Also, the expressions of TLRs and their association with the occurrence of IFIs in patients with AML are not studied. So, the novel aim of this study was to investigate the associations between the T-lymphocyte expression of TLR2 and TLR4 and the occurrence of IFIs in AML patients treated with intensive induction chemotherapy. Materials and Methods One hundred twenty two newly diagnosed AML patients were evaluated. The laboratory diagnostic techniques for IFIs include culture, microscopic examination, histopathology, galactomannan assay and PCR. The expressions of TLR2 and TLR4 were analyzed by flow cytometry. The Control group included 20 age and sex-matched individuals. Results There was a significant increase in the expression of TLR4 in AML patients with IFI compared to healthy controls (p = 0.001). TLR2 and TLR4 expressions increased significantly in AML patients with mixed fungal and bacterial infection compared to healthy controls (p= 0.002 and p=0.001, respectively). Conclusion TLRs expressions could be important biological markers for the occurrence of IFI in non-M3 AML patients after intensive induction chemotherapy.
