This allows improved pregnancy results and the avoidance of unintended births. Teenagers’ views on using contraceptives are influenced by the information available at their disposal. The study assessed the influential factors affecting the utilization of modern contraceptives among the youth in Akuse in the Eastern Region of Ghana. Methods: The data for the study were gathered from 378 consented youth aged 15 - 24 years using a quantitative cross-sectional study design and a well-structured questionnaire. Person’s Chi-Square test was adopted to measure the association between the outcome variable and selected independent variables. Logistic regression models were utilized to measure the odds of the factors influencing modern contraceptive use among the respondents. Results: The results of the study suggested a high knowledge level of contraceptives;however, the prevalence of utilization was low. The level of education and age were factors found to influence the uptake of contraceptives. A bivariate analysis to examine the association between selected socio-demographic variables revealed that educational level (p = 0.044), religious affiliation (p = 0.002), and ethnicity (p = 0.016) were statistically associated with modern contraceptive use among the respondents. All other tested demographic variables including the age groups, gender, marital status, and residential status proved otherwise at the observed p-values greater than the 0.05 threshold. Respondents who indicated staying with partners were 6.79 times more likely to use contraceptives compared to their counterparts staying with a parent, after controlling for all other covariates. Conclusions: Based on the findings of this study, it was concluded that high contraceptive knowledge influences the choice of contraceptive preferred by the youth, and contraceptive use is also influenced by the advancement in age and educational level of the youth. It is however recommended that parents, guidance, and teachers be entreated to offer relevant and timely sexual information or education as these will most likely improve the uptake of modern contraceptives among the targeted population.展开更多

Fundamental ideas of the method are inspired from soccer leagues and based on the competitions among teams and players. Like other meta-heuristic methods, the proposed technique starts with an initial population. Population individuals called players are in two types: fixed players and substitutes that all together form some teams. The competition among teams to take the possession of the top ranked positions in the league table and the internal competitions between players in each team for personal improvements results in the convergence of population individuals to the global optimum. Results of applying the proposed algorithm in solving nonlinear systems of equations demonstrate that SLC converges to the answer more accurately and rapidly in comparison with other Meta-heuristic and Newton-type methods.展开更多

Taking the data for the 2009 season, the input used by the teams is approached by the total expenses which include players’ wage bill and wage of the support staff and other miscellaneous expenses. Output is measured by the points awarded, net run rate, profit and revenues. Efficiency scores are highly correlated with the performance in the league with a few exception, and when decomposing inefficiency into technical inefficiency and scale inefficiency it can be shown that the largest part of inefficiency can be explained by suboptimal scale of production and ineffficient transformation of inputs into outputs.展开更多

[Method] Through the discussion of climate background, circulation characteristics, subtropical high and ocean temperature of the severe drought in Alashan League in Inner Mongolia during the flooding time, the potential causes of drought in Alashan League in summer in 2010 were discussed. [Result] The circulation around Alashan League and surroundings in 850 hPa was weak. Especially the southerly was extremely weak and it restricted the transportation of southerly water vapor towards Inner Mongolia, which was one of the direct reasons of drought; the 500 hPa high pressure ridge controlled Alashan League, and resulted into long-term drought and lasting high temperature. The summer seasonal wind was weak and arrived land in Alashan League. The northwest pacific subtropical high was large and strong. Only when subtropical high was strong and merged as well as strengthened with high pressure ridge around middle and high latitude in the lower reaches 130°-140° E, can rain be generated. However, the latter condition was limited in summer in 2010. When the ocean temperature around 30°-50° N and 140°-150° E was low in the north and high in the south, there would be less rain in Alashan League. [Conclusion] The study provided relevant information and technological support for the drought disaster warning forecast, drought observation system, and disaster prevention and mitigation measures.展开更多

Only one team (Toronto Maple Leafs) was more likely to be involved in a fight at a home game than at an away game. Teams that fought proportionally more often in the second half of the season made the playoffs;teams that fought significantly less often did not. And, long distance air travel (flights involving more than 1000 miles or trips that required crossing at least one time zone) resulted in disproportionately more games with fights for eight different NHL teams.展开更多

Fundamental ideas of the method are inspired from soccer leagues and based on the competitions among teams and players. Like other meta-heuristic methods, the proposed technique starts with an initial population. Population individuals called players are in two types: fixed players and substitutes that all together form some teams. The competition among teams to take the possession of the top ranked positions in the league table and the internal competitions between players in each team for personal improvements results in the convergence of population individuals to the global optimum. Results of applying the proposed algorithm in solving nonlinear systems of equations demonstrate that SLC converges to the answer more accurately and rapidly in comparison with other Meta-heuristic and Newton-type methods.

Efficiency scores are highly correlated with the performance in the league with a few exception, and when decomposing inefficiency into technical inefficiency and scale inefficiency it can be shown that the largest part of inefficiency can be explained by suboptimal scale of production and ineffficient transformation of inputs into outputs.
文摘[Objective] The causes of drought in summer in Alashan League in 2010 were discussed. [Method] Through the discussion of climate background, circulation characteristics, subtropical high and ocean temperature of the severe drought in Alashan League in Inner Mongolia during the flooding time, the potential causes of drought in Alashan League in summer in 2010 were discussed. [Result] The circulation around Alashan League and surroundings in 850 hPa was weak. Especially the southerly was extremely weak and it restricted the transportation of southerly water vapor towards Inner Mongolia, which was one of the direct reasons of drought; the 500 hPa high pressure ridge controlled Alashan League, and resulted into long-term drought and lasting high temperature. The summer seasonal wind was weak and arrived land in Alashan League. The northwest pacific subtropical high was large and strong. Only when subtropical high was strong and merged as well as strengthened with high pressure ridge around middle and high latitude in the lower reaches 130°-140° E, can rain be generated. However, the latter condition was limited in summer in 2010. When the ocean temperature around 30°-50° N and 140°-150° E was low in the north and high in the south, there would be less rain in Alashan League. [Conclusion] The study provided relevant information and technological support for the drought disaster warning forecast, drought observation system, and disaster prevention and mitigation measures.
文摘The ulnar collateral ligament(UCL) is a vital structure to the overhead athlete,especially the baseball pitcher.For reasons not completely understood,UCL injurieshave become increasingly more common in major league baseball(MLB) pitchers over the past 10 years.UCL reconstruction(UCLR) is the current gold standard of treatment for these injuries in MLB pitchers who wish to return to sport(RTS) at a high level and who have failed a course of non-operative treatment.Results following UCLR in MLB pitchers have been encouraging,with multiple RTS rates now cited at greater than 80%.Unfortunately,with the rising number of UCLR,there has also been a spike in the number of revision UCLR in MLB pitchers.Similar to primary UCLR,the etiology of the increase in revision UCLR,aside from an increase in the number of pitchers who have undergone a primary UCLR,remains elusive.The current literature has attempted to address several questions including those surrounding surgical technique(method of exposure,graft choice,management of the ulnar nerve,concomitant elbow arthroscopy,etc.),post-operative rehabilitation strategies,and timing of RTS following UCLR.While some questions have been answered,many remain unknown.The literature surrounding UCLR in MLB pitchers will be reviewed,and future directions regarding this injury in these high level athletes will be discussed.

文摘Background:Sexual and gender minority youth frequently experience bullying,which often contributes to higher depressive symptoms and lower self-esteem.Given that physical activity(PA)can mitigate depressive symptoms and improve self-esteem,we examined the moderating effect of PA on the relationship between bullying and mental health among sexual and gender minority youth.Methods:Data from the Lesbian,Gay,Bisexual,Transgender,and Queer National Teen Survey(n=9890)were analyzed.Hierarchical regression analyses examined the influence of history and frequency of being bullied,PA,and the interaction of these variables on depressive symptoms and self-esteem.Simple slopes analyses were used to probe significant interactions.Results:Results indicated the importance of accounting for bullying history when examining effects of PA on mental health.PA was negatively related to depression(t=-4.18,p<0.001)and positively related to self-esteem(t=12.11,p<0.001).Bullying frequency was positively related to depression(t=19.35,p<0.001)and negatively related to self-esteem(t=-12.46,p<0.001).There was a significant interaction between bullying frequency and PA for depression(t=4.45,p<0.001)and self-esteem(t=-4.69,p<0.001).Post hoc analyses suggested that the positive effects of PA on mental health may be limited to those not bullied because it had a negligible effect on those who were bullied.Conclusion:Results suggest that sexual and gender minority youth exercise interventions aiming to improve mental health should first address bullying history;otherwise,their effectiveness may be limited to those who have been bullied.
文摘The authors use data from fight logs during the 2016-2017 regular National Hockey League (NHL) season to test for a difference in the proportion of games with and without fights for each of the thirty NHL teams. Only one team (Toronto Maple Leafs) was more likely to be involved in a fight at a home game than at an away game. Teams that fought proportionally more often in the second half of the season made the playoffs;teams that fought significantly less often did not. And, long distance air travel (flights involving more than 1000 miles or trips that required crossing at least one time zone) resulted in disproportionately more games with fights for eight different NHL teams.

文摘BACKGROUND Anterior cruciate ligament(ACL)injuries represent detrimental injuries in the National Football League(NFL).A significant portion of these injuries often occur in preseason exhibitions.The Coronavirus disease 2019 pandemic presented a unique disruption to preseason NFL football with the cancelation of all preseason games.AIM To compare the incidence of ACL tears through the first eight weeks of the NFL season in 2020 to the mean incidence over the previous 5 seasons(2015-2019)and determine if there was any change in incidence with the elimination of the preseason.METHODS NFL players who suffered ACL tears during the preseason and first eight weeks of the NFL season from 2015-2020 were identified.The number of ACL injuries for the 2015-2019 seasons was compared to the 2020 season for four different timeframes.For each analysis,the cumulative number of ACL injuries to that time point was used to calculate the percent difference for descriptive analysis.Additionally,the number of teams with at least one player suffering an ACL tear were identified and compared using Chi-Squared testing.Finally,a cumulative relative risk was calculated for each week played.RESULTS There were 14 ACL tears through the first four games of the 2020 season,a 118.8%(14 vs 6.4)increase in comparison to the 5-year average over the first 4 regular season weeks of 2015-2019.However,when accounting for injuries occurring during the preseason from 2015-2019,there were 18.6%(14 vs 17.2)fewer total ACL injuries through regular season week 4 with no significant difference in percentage of teams impacted when these preseason injuries were accounted for P=0.394.Results were similar(19 vs 17.2)over 8 total games played(whether regular season or preseason),and over 8 regular season games(P=0.196,P=0.600).CONCLUSION The elimination of the NFL preseason resulted in a higher rate of injuries during the first 4 games of the regular season.However,these increases are offset by the injuries typically sustained during the preseason.This suggests there may be front-loading of injuries over the course of an NFL season,such that players may be more prone to injury when the intensity of play suddenly increases,whether in the preseason or regular season.
