The objective of this study was to analyze the ranking scores in Paralympic judo athletes in different visual impairment classifications (B1, B2, and B3) and describe the frequency of athletes of each classification allocated in the first five and last five positions in the ranking list. A total of 488 judo athletes with visual impairment (332 male and 156 female) took part in this study. Data were extracted from the Official Ranking List, documented and organized by the International Blind Sports Federation, and analyzed according to sport classes (B1, B2, and B3) and weight categories. One-way analysis of variance was used to compare the scores among different groups. The main results showed that B1 athletes presented lower total and best scores compared to B2 and B3 counterparts in both female ( p = .020, p < .001, respectively) and male groups ( p = .010, p = .005, respectively). In addition, when analyzing the ranking list position, there was a higher percentage of B1 athletes in the last five positions in female (60%) and male groups (60%) than B2 and B3 athletes. Investigations about classification and competitive system can assist coaches and sports organizations to identify the appropriateness of the ranking system scores adopted for athletes with visual impairment. Our findings showed some issues when considering competitive programming that includes all visual impairment classes in the same category.

In the present study, data from an experiment with 10 purebred Holstein, Simmental and Jersey cows each were analysed to test the assumption that there are genetically low methane-producing animals. Methane emission of cows offered forage ad libitum and some concentrate was measured for 3 days in open-circuit respiration chambers in weeks 8, 15, 23, 33 and 41 of lactation. Individual cow data were analysed in five different ways: (i) plotting the trend of methane per unit of dry matter intake (DMI) and milk yield over time; relating measured methane production to estimates derived from equations based on either; (ii) DMI or (iii) nutrient intake; (iv) relating residual feed intake (RFI) to methane emission; and (v) analysis of variance of cow × measurement interactions. The Holstein, Simmental and Jersey cows emitted on average 25, 25 and 26 g methane/kg DMI, respectively. There was no indication of individual cows with persistently low or high methane yield per kg DMI and per kg milk. Measured methane emissions differed from estimated values without a clear pattern, and the relationship between RFI and methane emission of the cows was weak. Finally, analysis of variance failed to show distinct patterns of methane per unit of DMI and milk for individual animals. The apparent lack of persistence of individual animal differences in methane yields suggests that genetic determination of this trait is of minor importance in dairy cows.

The aim of this study was to document training strategies used by experienced trainers of the Icelandic pace racing horse. Data were obtained using a questionnaire, to which responses were received from nine trainers on the world ranking list in 250 m pace races and with a minimum of 12 years of experience of pace training. Training was commenced at an age of 5.4±1.0 years and the average time to achieve competitive condition was estimated to be 1.9±0.8 years. Horses were trained almost every day and the trainers described a variety of training methods. Interval training appeared to be common, while training at pace was performed less than twice per week. Mental aspects seemed to be a challenge for performance.

Experimental Treatments

Frequently imposed experimental treatments in biological research produce results which require evaluation in terms of interdependence between the factors under study. Data from a 2-factor calf-feeding experiment have been used to illustrate the inadequacy of over-all means in describing the treatment effects where factor interdependence existed. It was shown that, to make accurate appraisal of the treatment effects under these conditions, it is necessary to restrict consideration to the subtreatment means.

Significant Difference

Analysis of Means by Ranks is a nonparametric statistical test procedure that was developed in Bakir (1989) but has rarely been applied in practice. This paper modifies and applies Analysis of Means by Ranks to a case study data involving the comparison of three contract proposals. For comparison purposes, we analyze the same data using the well-known Analysis of Variance, Analysis of Means, and the Kruskal-Wallis test. Analysis of Variance and Analysis of Means are two parametric (assume data to be samples from normal populations) test procedures whereas Kruskal-Wallis and Analysis of Means by Ranks are two nonparametric (or distribution-free) procedures. This paper shows that the parametric tests fail to detect a significant difference among three contract proposals, while the nonparametric tests do.  The conclusions of the parametric tests are in doubt because a descriptive statistics analysis indicates that the required normality assumption is in doubt; the nonparametric conclusions are more trustful because the normality assumption is not required by nonparametric procedures.

The Impact

ABSTRACT. Background: The beginning of 2020, more precisely the month of March, when the Covid-19 pandemic was declared, represents the beginning of one of the darkest pages in the history of world sport. The reason is a well-known one, namely the fact that the implementation of measures to prevent the spread of the SARS-CoV-2 virus have led to the cessation of competitions and the training process, for certain periods of time, in almost all sports. The aim of this study was to see how these measures have influenced the sports activity in Romania, especially that of the sports organizations from Caraş-Severin County (C-S). Thus, a number of 43 sports organizations from CS County were targeted, of which 39.3% being clubs/associations that work only at the level of children and juniors, 12.5% are clubs/associations that have only senior team, and 48.2% are clubs/associations that have both senior team and children/junior teams. All participants agreed that information could be processed and used for scientific purpose, and the study has obtained Research Ethics Approval from The Scientific Council of the Babeș-Bolyai University of Cluj-Napoca. Methods: An online questionnaire survey was conducted, with 31 items, which aimed to outline an accurate picture of the existing situation among sports organizations, which was the situation of sports competitions in 2020, respectively the 2019-2020 season, which was the situation of the training process in the 10 pandemic months of 2020, but more importantly, what are the current situation of the training process and that of the competitive system. Results: Compared to the sports activity carried out at the level of CS county, a number of 8 team sports and a number of 12 individual sports were taken into account, the answers offered being in proportion of 73% from the coaches from team sports, and 27% from individual sports coaches. It was observed that in team sports 78% of the respondents showed that the 2020-2021 competitive season had not yet started until January 2021, while 14.6% it started and was interrupted. Only 7.3% of the teams are in full competition season, the 2020-2021 championship not being embodied due to the Covid-19 pandemic. It was also found that after the resumption of stopped training, as a result of the application of measures to prevent the spread of the pandemic, the number of children decreased both in individual sports and team games. Conclusion: Based on the results, we can see the negative impact of sports organizations that are in the lower leagues, as well as those that are at the level of children and juniors. The fact that training has not been resumed, the measures imposed by the pandemic, the fear induced by a possible infection with the SARS-CoV-2 virus can cause the disappearance of a significant number of sports organizations, which will have a negative effect not only on the performance sport, but also on the level of public health.

Prosocial Behaviours

This study analysed sighted students’ prosocial behaviour towards assisting their peers with visual impairment (VI) in inclusive secondary schools in Iringa Municipality, Tanzania. An embedded single case study design was used. Seventy six respondents, consisting of teachers and students with and without VI participated in the study. Data was collected through semi-structured and face to face interviews, focus group discussions, and closed-ended questionnaires. Data was analysed through thematic analysis and presented in tables and quotations of participants’ actual words. Results have indicated differences in prosocial behaviours between sighted day-students and sighted boarding students with the latter being more prosocial as a result of altruistic and egoistic factors; having a positive attitude and due to the influence of religion and school administration . Similarities between sighted students and those with VI were linked to sighted students’ prosocial behaviour. The latter students’ attributions, and misunderstandings among students. determined their prosocial behaviour towards assisting their peers with VI. Awareness raising and sensitisation of members of the community, as well as replicating the study in inclusive and co-education schools for students with VI are recommended in the paper.

This study aimed to test the reliability, sensitivity, construct and logical validity of an adapted Special Judo Fitness Test (SJFT) for judo athletes with visual impairment . Twenty judo athletes with visual impairments performed both the adapted SJFT with tactile and sonorous stimuli (experimental conditions) and the typically administered SJFT (standard condition). We used analyses of variance (ANOVAs) with repeated-measures to compare the groups’ SJFT performances, and one-way ANOVAs to compare different visual ability classes of athletes (B1, B2 and B3). We used t-tests to compare SJFT variables between elite and sub-elite groups. We set statistical significance for all tests at p < 0.05. The standard SJFT showed excellent test-retest reliability for number of throws and overall index (ICC = 0.91–0.95), and both sonorous and tactile sensitivity adaptations of the SJFT showed medium sensitivity for detecting performance changes. The number of throws and SJFT index were higher with the sonorous adaptation of the test, compared to the tactile and standard versions ( p < 0.001). Athletes who were blind (B1) presented similar performances to athletes who were partially sighted (B2 and B3) only on the SJFT with the sonorous stimulus. Moreover, only the sonorous SJFT adaptation discriminated between the performances of elite and sub-elite athletes ( p < 0.001). In conclusion, both SJFT adaptations showed excellent reliability and medium sensitivity on test-retest, but, only the SJFT with the sonorous stimulus seemed valid for assessing judo athletes with varying degrees of visual impairment, and only the sonorous stimulus SJFT discriminated elite from sub-elite athletes.

Background: Today, couples applying for divorce need more self-efficacy in their divorce management. Self-efficacy in divorce management helps divorcing couples make the right decision to continue their married life or leave. The present study aimed to determine the effect of divorce counseling based on Gottman's approach on self-efficacy in divorce management within couples who applied for divorce in Yazd. Methods: This quasi-experimental study was based on pre-test, post-test, and follow-up method in which the case-control group design was applied. The study population included all couples who applied for divorce in Yazd in 2017. We selected 32 participants using purposive sampling, who were then divided into experimental and control groups. In order to collect the study data, we used Zareei's self-efficacy questionnaire in divorce management. To analyze the data, we run multivariate analysis of variance (MANOVA), two-way analysis of variance, and repeated measurement tests. Results: The results of MANOVA analysis indicated that the experimental group used self-efficacy more frequently than the control group in divorce management and its subscales. Moreover, analysis of two-way variance showed that gender did not have a significant correlation with the training results. In other words, the effect of education was the same for both genders. Moreover, the results of repeated measurement analysis indicated significant differences between the levels (pre test with post test and follow up). Conclusion: Gottman-based divorce counseling affected self-efficacy in divorce management of couples applying for divorce in Yazd. The effectiveness of this training was the same for both males and females. As a result, for those couples who want to divorce, such training seems to be extremely necessary.   Keywords: Divorce Counseling, Tendency to Divorce, Divorce Management, Gottman, Self-Efficacy

Interest in epidemiology of tuberculosis in Sub-Sahara Africa has been activated by its reemergence in the mid-1990s because HIV and poverty have created a lethal combination that propagates TB transmission. Three provinces of Kenya that collectively contribute to about 56% of TB cases notified in Kenya were included in the study. Data for smear positive TB and TB HIV was extracted from existing database between 2003 and 2009. Data was analyzed to produce trends for each of the provinces, and descriptive statistics were calculated. To deduce existence of differences in gender, provinces, and years, analysis of variance was carried out with values and confidence intervals generated. There were more males (56%) than females affected by TB, but more females with dual infection. Females have a bimodal peak in age groups 15–24 and 25–34, while males have one peak age group at 15–24. The rate of decline for males was higher than for females. Significant differences were found in gender (), year (), and rate of HIV positivity across the provinces (). Declining trend in cases is attributed to effects of integrating TB and HIV services and therefore programs need to address barriers to integrate care.
