Abstract In addition to providing a means of obtaining accurate quantitative results for individual flex-cracking tests, such as the De Mattia or Du Pont tests, the application of discriminant function analysis suggests a basis for standardizing the entire test method, so that objection to the test for specification purposes is thus concerned only with the reproducibility of the results, a problem which can now be investigated with greater confidence and ease. In connection with the accuracy of the method it may be contended that much depends on the subjective attitude of the tester who grades the samples with the photographs. When half-scores were not employed, the accuracy was limited mainly by the coarseness of the scale. This suggests that the grading is objective and, although no comparison, based upon statistical methods, has been made to determine the discrepancies between operators, no circumstance has occurred to suggest that important divergencies of opinion do exist. In addition, the analysis has been repeated on a further series of fifty samples, and the values found for the scoring constants were not substantially different from those obtained in this investigation. There is thus good reason to believe that this method of assessing the results will form a valuable means of investigating the causes of variation in flex-cracking test results and of recording the conclusions from the tests. The author wishes to thank the Board of Management of the Research Association of British Rubber Manufacturers for permission to publish the results given in this paper.

The objective is to determine the methodological approaches to pedagogical control in physical education of girls aged 12-14.Materials and methods. The participants of the study were girls aged 12 (n = 31), aged 13 (n = 26), and aged 14 (n = 28).To achieve the tasks set, the study relied on the following methods: analysis of scientific literature, pedagogical testing and methods of mathematical statistics. To evaluate the functional and motor preparedness of the girls aged 12-14, we recorded the results of Stange and Genchi, Serkin and motor tests.Results. The standardized coefficients of the canonical discriminant function allow to determine the relation of the variables contribution to the function result. The first function explains the results variation by 86.8% (p < 0.001), the second — by 13.2% (p < 0.001). The above proves that pedagogical control is possible in physical education based on the classification of the age differences in girls aged 12-14, by the results of their functional, strength and coordination preparedness tested.The structural coefficients of the first canonical discriminant function indicate that a significant difference between the girls aged 12 and the girls aged 13-14 occurs in the level of development of their motor coordination, speed strength and the results of Stange’s test. The structural coefficients of the second canonical discriminant function indicate that a significant difference between the girls aged 13 and 14 occurs in the level of development of the static and relative strength of their arm muscles.Conclusions. The final pedagogical control of motor and functional preparedness of the girls aged 12-14 can rest on the first discriminant function with emphasis on the most informative variables.

The subject matter of coefficient factors is not a frequent object of analysis in the scientific literature. However, because of the use of this term in engineering tasks and because of the constantly changing manner of energy use (resulting from the dissemination of new appliances), there is a need for current analysis and possible revision of the approach based on coefficient factors. The aim of the paper is to compare currently recommended values of this coefficient in the task of estimating the peak output of installations on the example of standards applied in Poland. On the basis of smart metering data and statistical methods, coefficient factors for residential consumers supplied from the municipal distribution network were determined. The results were compared with the currently applied values in accordance with the industry standard issued by the Association of Polish Electrical Engineers (standard N SEP-E-002).

The study objective is to determine physical exercises modes when developing motor skills in girls aged 14. Materials and methods. The participants in the study were 40 girls aged 14. To achieve the objective set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, methods of mathematical experiment planning, discriminant analysis. Results. The first canonical function explains 73.3% of the variation in results, the second function – 21.6%, which indicates their high informativity (r1=0.898; r2=0.743). The analysis of canonical functions highlights the statistical significance of the first and second canonical functions (λ1=.067; р1=0.001; λ2=0.346; р2=0.001). The first and second functions have a high discriminative ability and value of interpretation with respect to the general totality. The number of repetitions for mastering the first and fourth series of training tasks has the largest contribution to the first canonical function. This indicates that the exercises for developing motor abilities and teaching to control movement time and muscular effort influence the effectiveness of teaching a press headstand and handstand. The number of repetitions for mastering the second and third series of training tasks has the largest contribution to the second canonical function. This indicates that starting and ending positions, and actions without which the exercise performance is impossible influence the effectiveness of teaching a press headstand and handstand. Conclusions. The discriminant function structure coefficients show that the training program effectiveness is determined by selecting the series of training tasks and their performance modes. To choose the most rational mode of exercises of the series of tasks when teaching girls aged 14 a press headstand and handstand, the first discriminant function can be used with an emphasis on the most informative variables.

ABSTRACTSex workers have been the protagonists and focus of HIV prevention campaigns and research since the late 1980s in Brazil. Through a review of national and international literature, combined with a history of sex workers' involvement in the construction of the Brazilian response, this article explores the overlaps and disconnects between research and practice in contexts of prostitution over the past three decades. We review the scientific literature on the epidemiology of HIV among sex workers and prevention methodologies. We conclude that although research focus and designs often reinforce the idea that sex workers' vulnerability is due to their sexual relationships with clients, their greatest vulnerability has been found to be with their nonpaying intimate partners. Few studies explore their work contexts and structural factors that influence safe sex practices with both types of partners. The negative effects of criminalization, stigma, and exclusively biomedical and peer education-based approaches are well documented in the scientific literature and experiences of sex worker activists, as is the importance of prevention programs that combine empowerment and human rightsbased approach to reduce HIV infection rates. We conclude that there is a need for actions, policies, and research that encompass the environment and context of sex workers' lives and reincorporate the human rights and citizenship frame that dominated the Brazilian response until the end of the 2000s. As part of HIV prevention efforts, female sex workers need to be considered above all as women, equal to all others.
