Published: March 2021

Background

Effective and efficient participant recruitment is a key determinant of the success of a research program. Previously reported recruitment strategies have displayed variable success rates in studies on women with polycystic ovary syndrome (PCOS).

Objective

This study aimed to evaluate the effectiveness and cost per participant of the recruitment strategies that we used in a prospective randomized controlled trial to examine the effects of exercise training among inactive women with PCOS, who are aged 18-40 years.

Methods

The 4 recruitment methods we used were as follows: (1) referral by health care providers or by word of mouth, (2) media (eg, local newspaper stories and radio interviews), (3) Facebook advertisements, and (4) unpaid advertisements including posters and websites. The proportions of potential, eligible, and enrolled participants recruited with each method were determined and compared using tests of proportion. The time investment and cost per participant enrolled were calculated for each recruitment strategy.

Results

Of 200 potential participants screened, 98 (49%) were recruited from unpaid advertisements (posters and websites), 70 (35%) from Facebook advertisements, 16 (8%) by referral, and 16 (8%) from traditional media (newspaper and radio). Every potential participant was recruited from separate means (ie, no participant was approached through more than one recruitment method). A total of 109 (54.5%) women were deemed eligible for participation in the trial, and 60 (30.0%) were enrolled. The proportion of potential participants who completed the trial was higher for those recruited from traditional media than from Facebook advertisements (n=7/16, 44% vs n=13/70, 19%, respectively; P=.03) or unpaid advertisements (n=7/16, 44% vs n=13/98, 13%, respectively; P=.002). The cost per participant was Can $18.21 (US $14.46) for Facebook advertisements and Can $43.88 (US $34.85) for unpaid advertisements. There were no direct trial costs for referrals or traditional media.

Conclusions

For this trial, each method was important for recruiting inactive women with PCOS because no participant reported learning about the trial through more than one method. Unpaid advertisements and Facebook advertisements helped recruit the largest number of participants in the trial, the former resulting in a higher cost per participant than the latter.

Published: March 2021

Thermoalkalophilic xylanases promise potential application in pulp biobleaching to reduce the use of toxic chlorinated chemical agents, which are harmful to the environment. In this study, a thermoalkalophilic endoxylanase gene (bhxyn3) originating from Indonesian indigenous Bacillus halodurans CM1 was cloned into yeast expression vector pPICZα A and expressed in Pichia pastoris KM71 under the control of AOX1 promoter. Recombinant P. pastoris expressed the highest final level of xylanase (146 U/mL) on BMGY medium after five days of cultivation. Optimization of xylanase production on a small scale was carried out by varying the methanol concentrations and the optimal xylanase production by the recombinant P. pastoris was observed in the culture with 2% (v/v) methanol after four days of the induction phase. The recombinant xylanase (BHxyn3E) was thermotolerant and alkalophilic, with an optimal temperature at around 55‐65 °C and under pH 8.0. The enzyme activity was slightly induced by K+, Fe2+, and MoO42‐. Enzymatic bleaching of bagasse pulp with no prior pH adjustment (pH 9) using BHxyn3E at 200 U/g oven dried pulp increased the lightness index (L*) and changed substantially the color a index (a*); however, the treatments did not change the whiteness index in a significant way. Therefore, further optimization and assessment such as adjustment of incubation temperature and pH in biobleaching were needed to reduce the use of harmful chemical agents in industrial applications.

Authors: Prvulović Nikola , Lilić Ana , Hadžović Miljan
Published: March 2021

Changes and deformities to the feet are frequent among athletes. The aim of this review paper is to determine the prevalence of foot deformities among athletes with various backgrounds, as well as to determine the influence of the deformities on motor task performance. The compiled studies were published between 2002 and 2018. The following electronic databases were used for the search: PubMed, MEDLINE, Google Scholar, EBSCO. The identified studies had to satisfy the following criteria: that they included athletes and that the subject of analysis were the differences in foot deformities in relation to performing motor tasks. Research papers on this topic were reviewed and analyzed. They are clearly organized in tabular form, with a clear outline of the details of the research. The results of 16 research papers are summed up. The most prevalent deformity among athletes is flat feet (pes planus). The studies indicate the various deformities which are prevalent in particular sports, and determine the changes in the feet of the athletes, in particular for the foot which plays a decisive role in certain sports. Individuals with flat feet scored lower results compared to individuals with normal arches in terms of time and reaction speed when performing motor tasks.

Published: March 2021

The main aim of the current research is to determine the differences and correlations of sport seasons and economic statistics between the highest paid soccer players in the world, with an ankle injury in addition to other injuries and without an ankle injury. By comparing highest paid soccer players in the world (N=95), i.e., a sub-sample of players with an ankle injury (N=44), and a sub-sample of players without an ankle injury (N=51), it is possible to conclude that significant differences were not found in the variables of age, market value, the number of matches completed, the number of goals scored and the number of assists, as well as in the derived variables of the value of one player's day and the value of one match. In the basic variables the number of days missed due to injuries (222.61±165.61 vs 124.98±110.59), the number of seasons with injuries (5.68±2.23 vs 4.53±2.73) and the number of matches missed due to injuries (35.32±28.07 vs 20.12±19.2), as well as in the derived variables of number of days missed due to injuries per year (40.4±29.33 vs 27.16±18.18), number of games missed due to injuries per year (6.23±3.83 vs 4.32±3.21), value of days missed due to injuries (£7,627±£5,898 vs £5,070±£3,634) and the value of matches missed due to injuries (£13,134±£12,461 vs £9,276±£9,158), statistically significant differences were determined. All determined values were higher in the sub-sample of players who, in addition to other injuries, suffered from an ankle injury as well. In the multivariate exploration of the structure of the basic research variables, the results obtained indicate a latent space that had an interpretable three-dimensional structure. The structure of the space indicated a functionally independent relationship between the frequency and intensity of injury, on the one hand, and the chronological age, the value of the transfer and the player's efficacy on the other. It can be concluded that sports injuries, and ankle injuries especially in elite soccer players, have significant economic reprisals.
RELATIONSHIP BETWEEN BASIC PERSONALITY DIMENSIONS AND DISPOSITIONAL COPING STRATEGIES IN VOLLEYBALL
Authors: Vesković Ana , Orlić Ana , Nešić Goran
Published: March 2021

Athletes' coping strategies are important factors that contribute to competitive achievement and psychological well-being. The first aim of the current study was to explore the direct and interactive effects of Five Factor personality dimensions on dispositional coping strategies. The second aim was to test the second-order factorial structure of the Dispositional Coping Inventory for Competitive Sport (DCICS). The sample included 166 female volleyball players of mean age 15.01 years (SD=.87), and mean sports experience of 4.81 years (SD=1.85). They completed the NEO-FFI inventory and DCICS. Explorative factor analyses indicated two second order solutions with high reliability coefficients: task- and emotion-oriented coping strategies. The Paired samples t-test showed that young female athletes more often apply task-oriented strategies than emotion-oriented strategies. The regression analysis showed that some Five-Factor personality dimensions independently predicted the use of higher order coping dimensions. Conscientiousness was the only positive predictor of task-oriented strategies. Neuroticism was positive and agreeableness is a negative predictor of emotion-oriented coping strategies. No interaction effects of personality dimensions on dispositional coping were founded. These findings suggest that the Five-Factor personality model can predict the coping strategies that athletes frequently use. Findings also emphasize the need for more studies aimed to investigate this complex relationship including potential moderator effects of different variables such as gender, sport experience, competitive achievement, and different sports disciplines.
KINANTHROPOLOGICAL ANALYSIS OF THE CORE

Published: March 2021

The aim of this research is to investigate existing research dealing with the topic of the structure, functional and morphological status of the muscles that make up the body's core, as well as how improving the core affects the advancement of sports technique and its efficiency. The term core most commonly refers to the trunk, or more precisely, to the lumbar region. Core muscles play a significant role in lower limb alignment and stability, associated with poor alignment and injuries. The development of the core strength to improve the efficiency of sports performance is a controversial issue that has yielded different results. The analysis of the scientific journal articles revealed that the specificity of the program for increasing lumbar stabilization with the appropriate sport or skill is of the utmost importance. Therefore, it is necessary to specialize training facilities so that they are suited to a specific sport branch or discipline.
PERCEIVED AUTONOMY, MOTIVATION CLIMATE AND INTENTION FOR PHYSICAL ACTIVITY. A COMPARATIVE STUDY OF STUDENTS BASED ON THEIR GENDER AND EDUCATIONAL LEVEL
Authors: Karaoglanidis Dimitrios , Mouratidou Katerina , Kanellopoulos Panagiotis , Karamavrou Sofia , Parisi Ioanna
Published: March 2021

The main aim of the present study was to examine whether perceived autonomy during physical education (PE) classes, the perceived motivation, and students' intentions for physical activity outside of school differ based on their educational level and gender. The sample consisted of 551 children (266 boys and 285 girls), of which 320 were attending primary school and 231 were attending high school. Four instruments were used for collecting data: (a) a demographics questionnaire; (b) the Perceived Autonomy Support in Physical Education scale (P.A.S. in PE) for assessing students’ motivation; c) the Learning and Performance Orientations in Physical Education Classes Questionnaire (LAPOPECQ) for assessing  the perceived motivational climate within the PE class, and (d) a questionnaire based on the Theory of Reasoned Action which assessed the participants' intentions for physical activity outside of school. The results showed that as children grow up and change educational levels, the perceived motivational climate with an emphasis on tasks, the sense of autonomy in PE, and the intention to exercise are on the decline. In addition, it appeared that girls exhibited less intention to exercise compared to boys, especially in the highest level of education, and were more likely to perceive the motivational climate in the PE lesson as task-oriented rather than ego-oriented. To sum up, the gender and educational level of students are considered two key factors for both motivation and a sense of autonomy in PE, as well as for their intention to exercise outside of school.

Published: March 2021

The aim of this review research was to determine the effects of the physical activity (PA) on obesity among the elderly. To compile existing studies on the effects of PA on obese elderly individuals, PubMed, SCIndeks, PEDro, J-GATE, DOAJ and Google Scholar electronic databases were searched. By analyzing and applying the set criteria, the final analysis included 20 studies, and the positive influence of the PA on the obesity of the elderly was confirmed. The greatest effect on the decrease in body mass was achieved by the simultaneous application of a combination of exercise programs and dietary regimen for a period of 6 months. It was concluded that combined programs of aerobics, weight training, flexibility and balance exercises for a period of at least 12 weeks lead to a mild decrease in body mass and the amount of fat mass, while maintaining and increasing lean body mass mostly in the form of muscle tissue. PA is an effective mean in reducing obesity, and thus its use among the elderly is recommended.

The aim of this study was to examine the differences in motor competence among children of different school ages, as well as whether there is a negative trend in the decline of these values with increased age. The research was conducted in a school environment, the sample consisted of 151 male and female children, age 7-11 years, divided into four approximately equal subsamples: first grade children N=36 (7.4±0.3 years, Mean±SD), second grade children N=41 (8.5±0.3 years, Mean±SD), third grade children N=40 (9.4±0.3 years, Mean±SD) and fourth grade children N=34 (10.4±0.3 years, Mean±SD). The Körperkoordinations test (KTK) assesses the coordination of the whole body and is intended for children aged 5-14 years. The test is internationally standardised and consists of 4 subtests from which the following variables emerged: single-leg hopping, walking backwards, two-legged lateral jumping, lateral movement platforms and Total KTK. The multivariate analysis of variance (MANOVA) revealed statistically significant differences between children of all ages in all tested variables, in the total (P=.00) and individual (p=.00) system of variables. These findings also indicated a negative trend of declining motor competence of children with increasing age. A similar trend was observed in the individual variables of the KTK battery. The increased involvement of physical education teachers and children in physical education classes is recommended in order to increase the development of children's motor competence through regular physical activities on a daily basis.

The aim of this study is to determine the state of postural disorders in the sagittal and frontal planes of the spinal column, as well as any gender differences in first-year elementary school students. The participant sample comprised 138 school children, 73 male and 56 female participants, all from the territory of the municipality of Knjaževac, Serbia. The measuring instrument, the Formetric 4D System, Diers, Germany was used for the assessment of postural disorders of the spinal column. The testing results were presented in terms of frequencies and percentages, while the chi-square independence test was used to determine differences in spinal deformity incidence between male and female participants. The results obtained indicate that, in the sagittal plane, deformity was present in a total of 73.9% of the sample (72.6% among the male and 75.4% among the female participants), whereas in the frontal plane this percentage amounted to 84.1% (84.9% among the male, and 83.1% among the female ones). Moreover, the results indicate that no statistically significant differences were found in terms of the incidence of postural disorders between male and female participants in the sagittal plane (sig=0.859) and in the frontal plane of the spinal column (sig=0.949). In view of the results obtained, it can be concluded that a high incidence of spinal postural disorders in both the frontal and sagittal planes was equally present in participants of both genders.

The aim of this study is to determine body composition (BC) factors that influence agility among adolescent soccer players (N=66), in U14, U16, U18 soccer teams of the Topola Sport Club. Agility tests (Dribbling test, Illinois test), Inbody 720 instrument measuring the BC, and Oxa Starter infrared timing gate instrument measuring speed the agility were used. Data are processed by the IBM SPSS Statistics 25 software. In addition to descriptive statistics, a correlation matrix analysis, linear regression and one-way analysis of variance (ANOVA) were also applied (p<0.05). A moderate correlation between agility with a ball and without a ball (r=0.595) is determined as well as between agility and BC parameters: Skeletal Muscle Mass, Intracellular Water Mass, Protein Mass, Mineral Mass (r=-0.453, -0.454, -0.453, -0.417, respectively) while the correlation between agility and Height, Mass, Body Mass Index, Right Leg Lean Mass, Left Leg Lean Mass, Extracellular Water Mass is less than moderate (r=-0.318, -0.329, -0.276, -0.332, -0.330, -0.374, respectively). A slight correlation is determined between agility with a ball and BC variables. No correlation was determined between Agility and Body Fat Mass. The influence of BC on agility is lower than expected. Using the scientific based approach and measurements, a complex exercise plan can be made for players and in this way young soccer players can be trained by using tailor-made and post-specified coaching methods.
MUSCLE ACTIVATION DURING FOREHAND AND BACKHAND DRIVES IN THE SPORT DISCIPLINE OF TENNIS
Authors: Koronas Vasilios , Koutlianos Nikolaos
Published: March 2021

Tennis is one of the most popular individual sports all over the world. Strength and trained muscles are required for a player in order to achieve a good backhand, forehand, volley or flat stroke. Especially while playing tennis are many kinds of muscles involved, including the lower body muscles, trunk muscles and upper body muscles. The purpose of this review is to present the activated muscles in the basic tennis movements of forehand and backhand and to improve the knowledge about their role in order to help tennis players and coaches to enhance their tennis performance and to reduce risk of injury. To support the present review, data were gathered from library and network databases using keywords such as tennis, muscles, forehand, and backhand for publications between 2015 and 2019. Overall, thirty-five references were detected and used. The literature showed that forehand and backhand drives are strokes that involve muscles not only of the upper limbs but also a series of more complex movements that start with the feet and end with the swinging of the tennis racket. The insight for the action of the muscles in tennis should be utilized in tennis players so as to better understand the muscular function which takes part in specific tennis movements and has a greater performance. In addition, this knowledge is considered strongly beneficial for the coaches and the favourable building of the training process.
О РОМАНИЗАЦИЈИ СТАНОВНИШТВА НА ЈУГУ ПРОВИНЦИЈЕ ДАЛМАЦИЈЕ НА ОСНОВУ ИСТОРИЈСКИХ ИЗВОРА (Примјери из источне Херцеговине)
Authors: Самарџић Глигор
Published: March 2021

The paper presents data on the politics of romanization of the population in the south of the province of Dalmatia (east Herzegovina) using historical sources. After the Roman invasion of Illyria and the introduction of education to the province of Dalmatia at the beginning of the 1st century AD, the Romans built a system of fortresses on important strategic points, followed by road construction, settlement construction, populating the area with veterans and the Italic people, giving civil rights and establishing a tradition of worshipping Roman gods. This was the time of not just territorial, but ethnic and infrastructural changes as well. According to the epigraph statues, the territory of today’s east Herzegovina was inhabited by the locals, as well as Roman citizens (cives Romani) during this period in history. The influence of the Italic people was considerable because the introduction and importance of the Roman culture and civilization, as well as the Roman lifestyle, were helped mostly by the Italic people who inhabited urban areas. They brought with themselves every single achievement of the Roman civilization, which influenced the locals in various ways. Epigraph statues, various archeological records and oral sources shed light, to a certain degree, on the different influences on the territory of east Herzegovina. East Herzegovina covers the area spreading from the left banks of the Neretva River in the west to the right banks of the Trebišnjica River in the east.

Published: March 2021

Over the past two decades, many researchers, as well as hotel management, conducted surveys on visitor satisfaction with service quality of hospitality products. However, there is a lack of investigation of the perceived quality of hotels products in Vojvodina whose economy is still in the stage of adjustment to the new economic conditions due to the transition and ownership transformation. Thus, the aim of this study is to identify all the specific factors of hotel product and to point out the necessity of strengthening them in order to reach the level of satisfaction of customers of services provided. Data were collected from a sample of guests staying at various city hotels in Vojvodina (Serbia), rated with 1 up to 5 stars. Two types of analyses were performed to reach this objective: the exploratory factor analysis (EFA) and after that, the one-way analysis of variance (One-way ANOVA) with the view of determining a substantive effect of factors in different hotel categories. The paper identifies five major attributes as the most influential factors of the hotel product quality, i.e. front office services, employees, hotel facilities, restaurant service and the location of facilities. The discussion of findings leads to some suggestions on how to reach the hotel-product improvement and the specialization of hotels.

Published: March 2021

Тhe protection of human rights is one of primary goals of police work in democratic societies. However, no society is immune to the various forms of illegal police work. Some of them, like police torture, are the hardest forms of illegal police activity and the inhuman treatment of citizens as well. The paper focuses on the aspects that appear to be essential, so the paper considers the most important aspects of the phenomenon of "police torture" - the basic meanings, causes, ways and consequences of its manifestation. Our goal is to remove certain doubts in the interpretation of this phenomenon, but also to increase the interest in investigating the appearance of torture in the police. Such a scientific study has not been conducted so far, so there is a need for further comprehensive investigations of the "police torture" phenomenon.
AN INTEGRATED DEA/AHP METHODOLOGY FOR DETERMINING THE CRITERIA OF IMPORTANCE IN THE PROCESS OF BUSINESS-FRIENDLY CERTIFICATION AT THE LOCAL LEVEL
Authors: Randjelović Milan , Savić Gordana , Stojanović Boban , Randjelović Dragan
Published: March 2021

The key problem in the application of multi-criteria decision methods is to determine the importance of the criteria.  That is the reason for the developing of a number of approaches for its calculation. Most of the used classifications divide them into two groups: subjective and objective. This  paper presents an integration, an analytic  hierarchy process (AHP) method as a subjective one, and the data envelopment analysis (DEA) method as an objective approach. The basic idea in the proposed procedure is to introduce objectivity into the process of criteria importance derivation with AHP by taking into account the weight obtained by DEA efficiency evaluation after introducing subjectivity in DEA, with an expert opinion.
A SYSTEMIC APPROACH TO IMPROVING INNOVATIVENESS IN HIGHER EDUCATION
Authors: Zlatanović Dejana , Nikolić Jelena , Nedelko Zlatko
Published: March 2021

Innovativeness can be seen as a major competitive advantage in organizations enhancing their effectiveness and enabling the basis for sustainable development. Innovations in higher education systems have an impact on all the systems elements, relationships as well as on the higher order system in which higher education institutions (HEIs) are embedded, ranging from individuals to organizations. A holistic approach to innovativeness in higher education is required in order to improve innovativeness. The paper deals with the issues of improving innovativeness in higher education from the viewpoint of Soft Systems Methodology (SSM), as a relevant interpretive systems approach. The main purpose of this paper is to demonstrate how this systemic approach can help to explore the complex and pluralist nature of management innovativeness in higher education and provide a foundation for improving innovativeness of HEIs. Accordingly, the paper contributes to reveal different perceptions and interpretations of HEIs’ relevant stakeholders on innovativeness, as well as to identify systemically desirable and culturally feasible changes which can improve innovativeness of HEIs. Findings will be useful for HEIs to improve their innovativeness.
UPSTREAM SUPPLY CHAIN DILEMMA – SINGLE OR MULTIPLE SOURCING
Authors: Anđelković Aleksandra , Milovanović Goran
Published: March 2021

Supply chains, as networks of companies, are focused on creating greater value to meet market needs with aim to achieve higher profitability. In this regard, all activities and processes within supply chain, starting from supply of raw materials until to the delivery of final products at the market, must be organized bearing in mind the aim of the supply chain. The focus of the paper is on upstream supply chian, and on solving the dilemma of supplying from single or muliple sources. The significance of this part of supply chain arises from the fact that any potential disorder or disruption in supplying can jeopardize making the value for consumers and the survival of the whole chain. Considering that due to the reduction in the complexity of upstream supply chain management, there is a trend of supplier base reduction, the aim of the paper is to determine how much this trend is present in the Republic of Serbia, with a special emphasis on the food industry. Using by regression analysis  and based on the results of empirical research.

This paper presents the results of research on the use of computers and the Internet in teaching and learning at the Faculty of Special Education and Rehabilitation. The sample consisted of 198 students of different departments and levels of study. The aim of the research was to determine to what extent teachers and students use computers and the Internet in teaching and learning. Specific objective was to determine the differences in the use of computers and the Internet depending on the year of study. The results show that the highest percentage of respondents (98 %) use the computer, and all the respondents use the Internet. Computers and the Internet are used extensively for entertainment. There is a need for the faculty to make its information resources more available to students. There are differences in the way computers and the Internet are used, as well as the students’ interaction with teachers and colleagues, depending on the year of study. It is recommended to direct students to a higher level of interaction and collaborative work in the performance of study tasks.
COMPARATIVE FRAMEWORK FOR THE ENVIRONMENTAL LIABILITY INSURANCE
Authors: Uzelac Ozren , Lukinović Mario
Published: March 2021

Growth of population and economic activity contribute to the increasing number of ecological incidents, which derive from different sources causing multiple types of pollution. Legal framework for selling this type of insurance was created by the introduction of the mandatory pollution liability insurance and the adoption of the insurance terms and conditions.            In this paper, the author deals with several legal aspects of environmental liability insurance and those types of losses. Particular focus was on the notion of the ecological loss and object of coverage, insured event and period of insurance, sum insured and insurer duty.            Authors conclude that the separation of the insurance (and terms and conditions) against environmental liability into a stand-alone product could be the next step in developing insurance conditions of the domestic insurance companies.
DO SOCIO-CULTURAL FACTORS MATTER IN CREATING THE GENERAL LEVEL OF CONSUMER ETHNOCENTRISM?
Authors: Kostić Milan , Stanišić Nenad , Marinković Veljko
Published: March 2021

The aim of this study is to assess the impact of certain socio-cultural factors on consumer ethnocentrism, as well as to measure the impact of consumer ethnocentrism on the purchase of domestic products. In this context, the paper presents and tests a new model that contains five potential antecedents of consumer ethnocentrism (national identity, cultural openness, patriotism, religiosity, animosity towards the European Union). The results indicate that patriotism stands out as the strongest antecedent of consumer ethnocentrism. Interestingly, the study confirmed the statistically significant and relatively strong impact of animosity towards the European Union (EU) on the general level of consumer ethnocentrism. On the other hand, cultural openness does not belong to the group of statistically significant drivers of consumer ethnocentrism. The originality of the study lies in the specific construction of the research model, which is coloured with sociocultural variables - especially patriotism, religiosity and animosity towards the EU.
STATE LIABILITY FOR NON-PECUNIARY DAMAGES IN THE JURISPRUDENCE OF THE EUROPEAN COURT OF HUMAN RIGHTS
Authors: Raičević Nebojša , Radivojević Zoran
Published: March 2021

Non-pecuniary damages are a form of just satisfaction that the ECtHR may award if a violation of protected rights is found. These damages can be claimed by individuals, groups of persons, non-governmental organizations and states, whereby the awarded amount must be distributed to individual victims. However, for the Court to award compensation for non-pecuniary damage, several requirements must be met. The Court has awarded compensation for non-pecuniary damage on several grounds, such as pain, stress, anxiety, frustration, embarrassment, humiliation, and loss of reputation. Unfortunately, the criteria for determining the amounts of compensation for moral damage are still not clear and precise, so they have been determined by the Court on an equitable basis, taking into account its case-law standards.
LEGALLY RELEVANT DAMAGE
Authors: Simonović Ivana
Published: March 2021

The author analyzes legally relevant damage - a concept used by the Study Group on European Civil Code in order to define those losses for which a legal redress is given under the tort law. There are eleven particular instances of legally relevant damage caused either to one’s personality, rights or property. What is also important are the infringements of other rights and interests, but they need to satisfy additional criteria in order to be recognized as legally relevant damage. Only such rights that enjoy protection against everyone are protected, therefore, anyone can infringe them. Interests are also protected if they satisfy the requirements to be worthy of legal protection.

Published: March 2021

This work presents the results of a multidisciplinary research focused on the contextual study of the grave goods of six pre-Hispanic cemeteries of the San Pedro de Atacama oasis, Antofagasta Region, Chile. The main objective was to deepen the social and ritual aspects of the prehispanic religious system in Atacama (500-1500 AD), based on the archaeological evidence of the hallucinogenic paraphernalia to elucidate the identity of the individuals carrying it and verify the hypothesis about their status as members of the Atacamenian elite. Databases with the information transcribed from the Le Paige Notes for these cemeteries served as a basic instrument; from them, the statistical analysis was structured according to artifact categories that allowed us to establish correlations between the different components of the mortuary offerings, comparing those that included elements of the psychotropic equipment with those that lacked them. Thus, differences emerged in the management of certain goods that made up the “circle of materializing objects” of the Atacamenian elite. The foregoing raises the existence of different artisan specializations between ayllus and status diferences within this society, as well as the control of interregional exchange circuits by said elite.
De las tabernas a los sistemas rotativos de contratación
Authors: Santibáñez Rebolledo Camilo Andrés
Published: March 2021

This paper is about the hiring practices and mechanisms of favoritism and retribution waged by foremen and workers in some Chilean docks during the first decades of the 20th century. Based on press and business bulletins from the docks of saltpeter and the Concepción area, the conclusion argues that this favoritism was based on a mechanism of retribution constituted mainly by the consumption of alcohol that the workers made in taverns associated with the foremen who nominated the crews. The workers’ way of answering this arbitrariness were the rotating systems for the distribution of the work that they struggled to establish and keep during 1918 and 1923: the “redondilla” and the “turno numerado”.
Identidades, fronteras y violencia de género
Authors: Guizardi Menara
Published: March 2021

The article derives from a review of the state of the art on identities, gender and borders that recovers the post-Marxist anthropological critic of four South American authors. I will start with the debate of Darcy Ribeiro and Cardoso de Oliveira about identities, continuing with Grimson’s discussions on borders and identifications in South America, and I will reach Segato, in her arguments about the elementary structures of gender violence. In the final section, I return and synthesize the central aspects of the critical turns discussed throughout the text, and I will establish some approximations for new analytical proposals.
