Seasonal variation and the effect of the transition period on physical fitness parameters in youth female soccer players
This study examined seasonal variation and the effect of the transition period on physical fitness parameters in female youth soccer players. Twenty-four players (13–17 years old) were assessed through field and laboratory testing. They completed laboratory testing three times: (1) at the beginning of the season (post-preseason), (2) at the end of the regular season (postseason), and (3) following the transition period (preseason). Field testing was conducted post-preseason and postseason. Results indicated that weight and body fat significantly increased from post-preseason to postseason and following the transition period. A paired samples T-test revealed that the players performed significantly better in the vertical jump and 30 m sprint test (all p < 0.01) postseason compared to post-preseason. Also, it was indicated that torque production for the right quadriceps, left quadriceps, and right hamstring (all p < 0.01) was significantly reduced after the transition period by 10%, 11.8%, and 10.5%, respectively. Cardiorespiratory measurements demonstrated that performance on an incremental cardiopulmonary treadmill test, maximal oxygen consumption, velocity at the first ventilatory threshold, velocity at the second ventilatory threshold, and velocity at maximal oxygen consumption (all p < 0.01) were significantly reduced postseason and following the transition period. Based on the results, coaches and trainers should primarily focus on maintaining the aerobic capacity of the players during the season, as it has been indicated to be reduced from the beginning to the end of the competitive period (VO2max reduced by 3.3%). In addition, they should focus on maintaining lower body strength and aerobic capacity during the transition period
Special duties in the period of the risk of bankruptcy
The subject of this paper is the analysis of the characteristics of the legal institution of the special duties towards a company during specific period of a company's operation, which we call the period of the risk of bankruptcy. After a short presentation of the basic features, the author deals with the time frame and specifics of the period of risk. Besides, the author analyses the characteristics of the special duties, regarding the subject, object, types of duties, and liability. The purpose of the analysis is to assess the justification of regulation on special duties, as well as to assess the necessity for adjusted interpretation of the existing regulation. The author concludes that in Serbian law, there is no need for a regulation on special duties, but he emphasizes that the adjusted interpretation, in accordance with the characteristics of the period of the risk of bankruptcy, is possible and useful
Analysis of the Association between Internal and External Training Load Indicators in Elite Soccer; Multiple Regression Study
The aim of this study was to identify the external training load (ETL) variables that are most influential on the session rating of perceived exertion (sRPE) during elite soccer training. The participants (n = 29) were adult male soccer players from a single team that competed in Croatia’s highest national soccer competition in the 2021/2022 season. Data were collected using the 10 Hz Global Positioning System from 66 training sessions, and a total of 1061 training observations were undertaken. The univariate and multivariate relationships among the predictors (ETL variables) and the criterion (sRPE) were assessed using forward stepwise multiple regressions and Pearson’s correlations, respectively. ETL variables explained 63% of the variance in the sRPE (Multiple R = 0.79; p < 0.01), and the model was successfully cross-validated. The significant partial regressors were total distance (β = 0.66), metres per minute (β = −0.47), high-intensity accelerations (β = 0.22) and decelerations (β = 0.18), and sprint distance (β = 0.14). All ETL variables were significantly correlated with the sRPE (all p < 0.01), with the highest correlations found for total distance covered (r = 0.70) and high-intensity accelerations and decelerations (r = 0.62 and 0.65, respectively). Such results show that (i) the total distance and acceleration rates during the training sessions are the most important predictors of the sRPE, and (ii) a combination of different ETL variables predicts the sRPE better than any individual parameter alone. This study shows that both the volume and intensity of training are related to players’ internal responses. The findings ultimately provide further evidence to support the use of sRPE as a global measure of training load in soccer players
Municipal bonds as a form of local government financing
Increasing demands for the improvement of the standard of living of citizens at the local level result in a great need of the local authorities to find new financing sources. The experience of developed countries and the fact that traditional sources of financing of local governments are insufficient point to the growing importance of municipal bonds. The author emphasizes the importance of the use of municipal bonds as a necessary condition of economic growth and development of local authorities. The author emphasizes the practice of developed countries and presents a contemporary analysis of the concept, types and characteristics of municipal bonds, and also of the legal framework for the procedure of their issuance and economic feasibility of their use.
Special attention is paid to the study of the secondary market of municipal bonds and its main features are identified. The author stresses the insolvency of the secondary market of municipal bonds, whose consequences are reflected in the fact that, compared to individual investors, institutional investors trade under more favorable conditions in this market. Concrete proposals are given so that, contrary to many markets around the world, the liquid secondary market of municipal bonds could be brought to life in Serbia.
The author deals with the activities of local governments in the Serbian capital market, their possibilities, limitations and conditions under which they borrow in the market. Based on the conducted research, the author determines the optimum contributions of this type of securities in the Serbian financial market. Crucial limiting factors of the development of this sector are defined, with a special focus on the low level of development of the Serbian market and a high degree to which this system centers on banks. A detailed analysis of the capacity of potential investors in municipal bonds of local governments in Serbia is made, with an emphasis on the sector of individual citizens, which holds the greatest potential necessary for further market development of the municipal debt
FENOMENOLOŠKE KARAKTERISTIKE TERORIZMA KAO TEŠKOG OBLIKA POLITIČKOG KRIMINALITETA
In the last few decades, terrorism, as a severe form of violence, has grown into one of the greatest and almost unsolvable challenges for individual states and the international community alike. The author has tried to contribute to a comprehensive scientific explanation of terrorism as a serious form of crime of violence and its phenomenological characteristics. The author points out that scientific researchof the methods, contents, forms and phenomenological characteristics of terrorism may contribute to creating conditions for effective suppression and counteracting of this form of violence. The study of terrorism and its phenomenological characteristics is important because it leads to reaching a consensus on this form of violence and its main features, and in conjunction with the research on terrorism from the ideological, philosophical, ethical and other aspects, it ultimately creates sound grounds to successfully counteract terrorist activities.Terorizam kao težak oblik kriminaliteta nasilja, poslednjih decenija, je izrastao u jedan od najvećih i skoro nerešivih izazova kako za državu tako i za međunarodnu zajednicu. Autor je pokušao da doprinese sveobuhvatnom naučnom objašnjenju terorizma kao teškog oblika kriminaliteta nasilja i njegovih fenomenoloških obeležja. Pored toga, autor je pokušao da ukaže da se pronalaženjem i spoznajom metoda, sadržaja, pojavnih oblika i fenomenoloških obeležja terorizma, ide korak napred ka kreiranju uslova za uspešno suprotstavljanje ovom obliku kriminaliteta nasilja. Izučavanje terorizma i njegovih fenomenoloških obeležja je značajno jer se time postiže konsenzus oko oblika ispoljavanja i njegovih glavnih karakteristika, koji će, uz rezultate istraživanja terorizma sa ideološkog, filozofskog, etičkog i drugih aspekata, stvoriti zdravu osnovu za uspešno suprotstavljanje terorističkim aktivnostima

Theoretical Foundations and Collective Programme of Constructivism in Russian Avant-garde Painting
Russian art studies traditionally approach Constructivism as a movement that was opposed to Suprematism. The author of this article, however, believes that both of these movements shared a number of characteristics. They both originated in the Cubist aesthetics and rejected traditional figurative art. They both sought to discover the `new way of seeing' in their effort to develop original painting techniques for this novel multi-dimensional reality. The author demonstrates how the Constructivists put these principles into practice. Constructivists and Suprematists adhered to similar principles and adopted similar techniques when working with material. As a result, in their search for a new style, they tended to follow similar paths. Their creative method is based on dissolving visible forms into the simplest (geometrical) primary elements and recombining these fragments into the new reality. This inevitably raised the question about the relationship between art and life. Constructivists went even further and proposed the ideology of `production art', that is, art that served a practical purpose for the society. Thus, the key Constructivist concepts and ideas were determined by the problems that this movement sought to address - these were the same problems which their precursors (Cubists and Suprematists) had failed to solve. Constructivism was, therefore, the next stage in the development of Russian Modernism
Impact of residential status on sports activity, anthropometric characteristics and motor abilities of adolescents
The world's leading health institutions warn that adolescents do not meet the minimum level of physical activity necessary for the proper physical development of young people, which is considered one of the main problems of public health. In addition to personal preference, environmental and cultural factors play an important role in the involvement of young people in sports. This study aimed to examine potential differences in involvement in sports, anthropometric characteristics and motor abilities, in adolescents of different residential statuses. The sample included 83 adolescents, of whom 45 (54.2%, 13.51±0.55 yrs) were from urban areas and 38 (45%, 13.45±0.50 yrs) were from rural areas in the Belgrade region. Surveying detected their involvement in sports, and anthropometric characteristics were assessed through body height (BH) body mass (BM), body mass index (BMI), and motor abilities through explosive strength of lower and upper extremities and agility. A Mann-Whitney U test has shown that place of residency impacts involvement in sports and motor abilities, while there was no impact on anthropometric characteristics. Cohen's criteria (r) detected the level of impact. Adolescents from urban areas are more involved at sports and have better motor abilities. There is no difference in anthropometric characteristics. Considering the relatively small sample of respondents and variables assessed, the obtained results can hardly be generalized. However, this does not diminish the importance of the present study which examined the urban-rural state of sports activity, anthropometric characteristics and motor abilities of adolescents in Serbia, thus making an important contribution to this fiel
PRANJE NOVCA KAO OBLIK EKONOMSKOG KRIMINALITETA U ULOZI FINANSIRANJA TERORIZMA
In terms of the dynamic of the international economic environment, economic organized crime has become a threat to national and international security. Political power acquired through illegal accumulation of economic power is rapidly expanding across all spheres of society. Money laundering and terrorist financing are global problems which have harmful effects on national economic, political, security and social structures. Terrorism cannot survive without financial means, which are very important for the terrorist organization. Therefore, the successful fight against terrorism and terrorist financing rests on adequate understanding of the concepts of money laundering and terrorism, and their interrelationships. In this paper, the author identifies money laundering as one of the main forms of economic crime. Using descriptive and historical method, an attempt was made to explain the scientific concept of money laundering and its importance to society and the state. In addition, the author explained the concept of terrorism and its financing and tried to find common characteristics of these seemingly incompatible phenomena, in order to emphasize the dangers of harmful consequences that could arise from inadequate opposition by the state and society.Ekonomski organizovani kriminal postaje pretnja nacionalnoj i međunarodnoj bezbednosti. S njegovom internacionalizacijom, posledice su sve štetnije jer se brzo prilagođava uslovima međunarodnog ekonomskog okruženja. Nelegalno akumulirana ekonomska moć je osnova za sticanje neposredne i posredne političke moći. To je snažna poluga širenja uticaja u svim sferama društvenog života, naročito za ostvarivanje kriminalnih ciljeva infiltracijom u legalne ekonomske tokove. Pranje novca i finansiranje terorizma su globalni problemi koji imaju štetne efekte na nacionalne ekonomske, političke, bezbednosne i socijalne strukture. terorizam ne može da opstane bez finansijskih sredstava, koja su itekako važna za terorističke organizacije. S toga, uspešno suzbijanje terorizma i finansiranja terorizma, kreće od adekvatnog shvatanja pojmova pranja novca i terorzima i njihove međusobne veze.
