‘Manna from heaven’: does the presence of central banks make technical analysis profitable?
Authors: Trivedi Smita Roy
Published: March 2021

Profitability of technical-analysis strategies has been explained with reference to central-bank intervention in markets (Neely 1998; LeBaron 1999; Saacke 2002). I argue that central-bank intervention is a market shock which leads to a generation of trends, making technical analysis profitable. Looking at empirical evidence from the Indian foreign-exchange market, I find returns calculated for the entire period are consistently and substantially higher than when intervention periods are removed. Thirteen out of the 15 strategies demonstrate higher returns with intervention periods included, compared to without intervention periods. The Kolmogorov–Smirnov sample tests show statistically significant differences in the returns between the entire period and the without-intervention period for four strategies, which is confirmed by bootstrap estimation. The paper contributes first by including actual trading strategies in the empirical testing of profitability of technical analysis and second by emphasizing the efficacy of technical analysis rather than the action of the central bank itself in explaining profitability, in a departure from the existing literature.
An Application of the Technology Acceptance Model to Individual Protective Measures (IPMs) Against Viruses
Authors: Haverila Matti , Husain Salma
Published: March 2021

This presentation describes Technology Acceptance Model (TAM) when using individual protective measures (IPMs) against the spreading of viruses like COVID-19. The constructs in TAM are perceived usefulness, and ease of use, attitude towards the use of IPMs and the actual use as well as social influence, which were measured with relevant indicator variables. The statistical method used in the analysis was Partial Least Squares Structural Equation Modelling (PLS-SEM). IPMs include personal protective measures for everyday use (e.g., voluntary home isolation, respiratory etiquette, and hand hygiene); Personal protective measures for influenza pandemics (e.g., voluntary home quarantine, and use of face masks in community settings); and Environmental measures (e.g., routine cleaning of frequently touched surfaces). The results indicate that all relationships were significant also so that the effect sizes were large to medium with the exception of social influence -> perceived usefulness and social influence -> attitude towards usage.
The Effects of Game and Student Characteristics on Persistence in Educational Games: A Hierarchical Linear Modeling Approach
Authors: Rahimi Seyedahmad , Shute Valerie , Zhang Qian
Published: March 2021

Persistence is an important part of student success—both in and out of school. To enhance persistence, we first need to assess it accurately. Digital games can be used as vehicles for measuring and enhancing persistence. The purpose of this study is to test the effects of (a) game-level characteristics (i.e., game mechanics and conceptual difficulty), and (b) student-related characteristics (e.g., students’ incoming knowledge and gender) on persistence in a game called Physics Playground. The participants in this study were 137, eighth and ninth-grade students from a K-12 school in Florida. We used a Hierarchical Linear Modeling Approach (HLM) to analyze the data. The major findings are (1) the degree of difficulty relating to both the physics concepts and game mechanics of each game problem are significant predictors of persistence, with the former being more effective than the latter in predicting students’ persistence, and (2) the number of gold and silver trophies students attained in the game were the only significant student-level predictors of persistence. We conclude by discussing the findings, the implications, limitations, and future research related to this study.
Impacts of Serious Games on Middle School Students’ Science Achievement and Attitudes towards Science
Authors: Toprak Yallıhep Emine Sena , Akcay Hakan , Kapici Hasan Ozgur
Published: March 2021

Developing students’ attitudes toward science is an important issue because societies need individuals who can contribute to scientific and technological developments. That’s why using various and different instructional tools in science education may have an impact on students’ attitudes towards science positively. Within this respect, the goal of the study is to investigate the effects of serious games on primary school students’ (fifth-grade) science achievement related to the topic of light and sound, and attitudes towards science. A quasi-experimental research design was used in the study. Fifth-grade students from two different classes were the participants in the current study. The data was gathered by the science achievement test and the attitude scale. The findings revealed that whereas students in the experimental group, who were taught by serious games, developed their attitudes towards science significantly positive, their counterparts did not. There was no significant effect of serious game on students’ achievement. This result showed that serious games as a different instructional tool may have crucial impacts on primary students’ attitudes toward science.

Qualitative Inquiry as a Method to Extract Personal Narratives: Approach to Research into Organizational Climate Change Mitigation
Authors: Birchall Jeff
Published: March 2021

The purpose of this article is to demonstrate that qualitative inquiry is highly effective at facilitating the extraction of personal narratives of senior managers in the New Zealand (NZ) public sector. Specifically, in this article I lay out the method used to develop theme-based narratives from semi-structured interviews with senior managers responsible for the delivery of the Communities for Climate Protection and the Carbon Neutral Public Service programs in NZ. In doing so, I demonstrate why qualitative inquiry is the ideal methodological approach for this kind of research program. Further, in demonstrating the research approach, this article may provide policy makers with insight into how to explore the cognitions of senior managers involved with carbon mitigation initiatives, and/ or the nuances of the initiatives themselves. This in turn may provide insight into how to weave climate and carbon management policies with other national strategic policies.

Tie Formation and Cohesiveness in a Loosely Organized Group: Knitting Together
Authors: Palmer Doris , Kawakami Atsuko
Published: March 2021

The purpose of this paper is to explore the elements of tie formation and group cohesiveness in a loosely organized group with no clearly stated goal, commitment, or purpose. We employed participant observation and personal interviews to discover factors related to group cohesiveness. With inductive approach based on our thick description of the study sites, such as meeting space and group conversations, we found the nature of relationships within these groups is affected by how each group was started and organized. Having an expressive leader may increase group cohesiveness in a loosely organized group, especially when the leader has a long history with the organization which confers authority as a leader. In addition, use of humor by an expressive leader enhances group cohesiveness. Finally, the arrangement of the group meeting space impacts group cohesiveness. The focus of previous studies was to examine group cohesiveness of task-oriented groups with measurable goals; however, this study compares two loosely organized groups.
Exploring the Subaltern Voices: A Study of Community Radio Reporters (CRR's) in Rural India
Authors: Patil Dhanraj
Published: March 2021

Despite India’s remarkable communication media revolution the rural subalterns remained uninformed, unheard and voiceless, who asks the question: Whose Media, Whose Voice? This created a space for community radio (CR) because it is of, for, and by the community. However, in spite of the alternative, counter-hegemonic, and participatory communication ethos, the contribution of CR’s and CRR’s lingered unexplored and unacknowledged. To bridge this gap, within the theoretical framework of alternative-media-theory this study has been undertaken. Based on case studies of India’s pioneer CR’s (Sangam Radio and Radio Bundelkhand) using media ethnography tools a qualitative inquiry was carried out. Findings suggest that CR’s can be seen as means of developing capabilities among the subalterns through equitable inclusion not merely as participants but as active producers, partners and managers. The dialectical, dynamic, non-hierarchical and citizen controlled journalism of CRR’s reflects antagonisms of reality and high level of community belongingness and responsibility that created fundamental distinctiveness-challenges to mainstream media. Finally, providing platform for expression enlarges the voices of the subalterns which will ultimately facilitate community dialogs and deliberations around local issues and helps to redefine their community identity in their own way and might lead to positive social change.
Understanding Visual Inquiry: A Review of Researching the Visual (2nd ed.)
Authors: Parylo Oksana
Published: March 2021

The growing popularity of visual research in social sciences along with the new possibilities offered by the developments in technology necessitate including visual inquiry in research methodology classes. Researching the Visual by Emmison, Smith, and Mayal (2012) offers a good introduction to visual research and can be used as a textbook for beginners in social inquiry. In this book, Emmison et al. carefully combine the history, examples, explanations, and new trends in visual research. Careful consideration is given to new approaches emerging within visual inquiry. In summary, while this book may be too basic for the experts in this field, it is an excellent introductory text for beginners—clear, engaging, and stimulating.
Parent-Adolescent Storytelling in Canadian-Arabic Immigrant Families (Part 1): A Grounded Theory
Authors: Ashbourne Lynda , Baobaid Mohammed
Published: March 2021

Interviews with 20 mothers, fathers, adolescent sons and daughters from Arabic immigrant families elicited descriptions of participants’ experiences of storytelling in their families. Constructivist grounded theory analysis of interview data provided an initial conceptualization of intergenerational storytelling during adolescence that both reflects and serves to influence parent-adolescent relationships as well as the broader cultural domain through story content, storytellers’ intentions, and responsive interaction. This preliminary substantive theory presents storytelling in immigrant families during adolescence as relationally grounded, influenced and expressed through a cultural/language “prism,” responsive and active in moving relationships toward or away from connection, and dependent on story content/context as well as the storyteller’s delivery and listener’s response. These findings have implications for extending theoretical conceptualization of family interactions during adolescence beyond conflict, monitoring, and peer influences. In addition, practical implications for supporting and understanding the day-to-day interactions that support parent-adolescent relationships and cultural minority families are highlighted.

Recruitment and Retention of Vulnerable Populations: Lessons Learned from a Longitudinal Qualitative Study
Authors: van Wijk Evalina
Published: March 2021

The main focus of the researcher’s study was to examine the lived experiences of intimate partners of female rape victims within the first six months post rape. Yet, many publications describing longitudinal qualitative studies of sexual assault fail to provide a detailed report on the processes followed, the difficulties experienced, as well as the reasons for such difficulties. To fill theses gaps, in this paper, the researcher describes the strategies applied to recruit and retain the participants for the entire six-month period post rape. The lessons learned during recruitment and data collection are also described. The research question that guided the study was: what are the lived experiences of intimate partners of female rape victims during the six months following the rape? The selection of study participants involved purposeful sampling. After providing their informed consent, nine intimate partners of female rape victims living in Cape Town, South Africa, participated in four separate face-to-face, semi-structured interviews as follows: (a) within 14 days of, (b) a month after, (c) three months after and (d) six months after the rape. Recommendations were made for future researchers to make them aware of the difficulties encountered in accessing, recruiting, and retaining vulnerable populations in longitudinal studies, especially in the field of research into sexual violence.
Evolution of Medical Students' Understanding of Systems-Based Practice: A Qualitative Account
Authors: Rutledge Brian , Jones Ellen , Bailey Jessica , Stewart James
Published: March 2021

Reflective writing is a useful tool in medical education to analyze student experiences and measure development of certain skills. This tool is particularly useful in identifying skill components of systems-based practice. These skills are necessary for any practicing physician, but are of particular importance as they are a required residency competency. There is now additional focus on systems-based practice with the passage of the Patient Protection and Affordable Care Act (ACA). In this qualitative, grounded theory study, the reflective writings of students at a United States medical school were analyzed using the constant comparative method to explore how the focus of a medical student progresses through the clinical curriculum. The interprofessional team of researchers specifically sought to determine if areas of medical student focus evolve vertically across the curriculum and if in the process students develop an understanding of systems-based practice. The data supported both of these objectives, and actively supports future research to identify ways, both inside and outside the curriculum, to leverage the students’ natural progression of focus in order to expand systems-based practice education.
Qualitative Methods in Higher Education Policy Analysis: Using Interviews and Document Analysis
Authors: Owen Gregory
Published: March 2021

This article is the second of a short series of works designed to articulate the results and research approach I utilized in my study Analysis of Background Check Policy in Higher Education. This second article focuses on the research development, design, and overall approach I utilized in addressing my research question which aimed to examine the history and experiences of Georgia Institute of Technology’s adoption of background check policy. This was achieved through interviewing relevant constituents and analyzing all available/related official policy documents associated with Georgia Tech’s Pre-employment Background Check Policy and Program. In my research approach, my conceptual framework consisted of considering four important policy dimensions, including the normative, structural, constituentive, and technical dimensions. This framework served as a basis and focus, shaping my research process, informing the methodological design, and influencing the selection of data-collection instruments. Using four very specific research design questions, I conducted my research through the lens of the social constructivist adopting an interpretivist approach utilizing a qualitative policy analysis methodology which included the use of interviews and document analysis to address my research question.

Authors: Lijadi Anastasia , van Schalkwyk Gertina
Published: March 2021

The lives of Third Culture Kids (TCKs) are characterized by their experiences of living among different worlds that could isolate them from social interaction and establishing long-term friendships. Exploring the experiences of ten TCKs, this paper reports on primary data gathered through the Collage Life Story Elicitation Technique (CLET) in order to gain an understanding of the meaning making of TCKs and their commitment and reticence in establishing relationships during their developmental years. In-depth thematic analysis indicated a struggle building intimacy and companionships and deep friendships, as well as difficulties with maintaining relationships with others and a possible fear of commitment. Implications for counselling of TCKs and their families are discussed.
Caught in the Middle: Chat(ting) about Black School Leaders
Authors: Hodges Demetricia
Published: March 2021

The purpose of this article is to “chat” about my experience using Eurocentric theories in racial and culturally centered qualitative inquiry. The challenge I face is that I believe researchers can use Eurocentric theories to conceptualize ‘appropriate’ frameworks to conduct rigorous culturally responsible and sensitive research that contributes to existing scholarly dialogue and empirical literature on culturally sensitive designs in the field of qualitative research. In this paper I use my research experience to address the question, “How can researcher(s) conduct culturally responsible and sensitive research?” I use autoethnography and writing as a method of inquiry to (re)present the multi-layers of within and in-between chats while being caught in the middle. Chat metaphorically represents introspective musings, scholarly dialoguing, analyzing, interpreting, (re)presenting and defending. I use Tillman’s (2002) culturally sensitive research frame as an analytic tool to critically analyze my research design. I argue that qualitative researchers of ethnic, racial and cultural communities can conceptualize appropriate frameworks from mainstream theories to conduct culturally responsible and sensitive research that can help transform the traditional knowledge of fields in education, educational leadership, urban education, and policy.
ESTIMATING OF DURABILITY INDEXES OF STRUCTURAL ELEMENTS BASED ON IDENTIFICATION OF THEIR DETERMINISTIC PROPERTIES
Authors:   Kharkiv National University of Radio Electronics, NEVLIUDOV Igor Sh. , ROMASHOV Yurii V. ,   V.N. Karazin Kharkiv National University
Published: March 2021

Durability indexes are presented as a consequence of some deterministic properties inherent in the system and (or) their elements, and it is proposed to determine the durability indexes on the basis of analysis of these properties. The most important for estimating the durability are properties related to the lifetime, and the deterministic properties basic for determining the indexes of durability, can be represented by the function of the dependence of the lifetime on the parameter defining the operational conditions. Estimating the durability indexes is reduced to identification of the deterministic properties representing the dependence of the lifetime on the parameter defining the operational conditions. An example of estimating the durability of pipes of superheaters of steam boilers demonstrates the proposed approaches with relatively less complexities. This particular example shows that deterministic properties can have a significant influencing on the durability due to significant differences between the density function of the parameter defining the operational conditions and the density function of the lifetime. The proposed approaches can be recommended for use to estimate the durability indexes of unique technical systems, such as high-power steam boilers and nuclear power reactors, which are usually manufactured in single batches, as well as to estimate the durability indexes of any systems at the stage of their development in order to compare the durability of different constructions.
REALIZATION OF TRACTION CAPABILITIES OF A TRACTOR WITH AN ELECTROMECHANICAL POWER TRAIN
Authors:   Belarusian National Technical University, ZHDANOVICH Cheslav I. , KALININ Nikita V. ,   Joint Institute of Mechanical Engineering of the NAS of Belarus
Published: March 2021

A method has been developed to assess the traction capabilities of a tractor with an electromechanical power train and determine the actual speed taking into account three restrictions: on the permissible slip of the tractor, the maximum power of the used internal combustion engine (ICE) and the permissible mode of operation of the traction induction motor (TIM). The developed mathematical model makes it possible to determine the drawbar pull and the actual speed of the tractor when regulating the TIM in the entire operating frequency range of the voltage supplied to the TIM for a comparative assessment of the traction capabilities of the tractor when using different gear ratios of the mechanical part of the power train (MPPT), as well as determine the slip and other parameters of the TIM when it works as a part of the electromechanical power train of the tractor. Calculations show that: 1) if the MPPT ratio is too high, the whole range of tractor operating speeds on the plowing will not be provided, and if the MPPT ratio is too low, the tractor will not be able to develop the maximum possible drawbar pull based on the permissible slip at any voltage frequency from the TIM control range without exceeding the nominal mode of operation of the TIM; 2) the higher the TIM gear ratio, the larger the section of the TIM frequency control range will be, in which the TIM will not be able to develop even the nominal slip due to the restriction on the permissible slip of the tractor, and for the same frequencies in this section, the TIM slip will be more limited at a higher MPPT gear ratio; the lower the transmission ratio of the MPPT, the more the nominal slip of the TIM will be exceeded during acceleration of the tractor with maintaining the maximum possible based on the permissible slip of the thrust force from the minimum speed to the speeds corresponding to plowing.

Published: March 2021

Konosirus punctatus is an important economic fish in the Northwest Pacific Ocean, especially along the coast of China, and an important substitute in the marine ecosystem. The aim of this study is to quantify the variation of sagittal shapes to discriminate the K. punctatus stocks between China coasts (Wei Hai, Yan Tai, Zhou Shan, Wen Zhou, Dong Ying, Hai Kou and Qing Dao) and Aomori (Am) in Japan by comparing the sagittal morphometric features. The sagitta variation of eight K. punctatus stocks was examined using nine shape indices (Roundness, Circularity, Form-factor, Rectangularity, Ellipticity, Radius ratio, Feret ratio, Aspect ratio and Surface density). Multiple comparisons on shape indices showed that three shape indices (Roundness, Feret ratio and Surface density) have significant differences between nine stocks. The comprehensive judgment accuracy rate is 54.5%. Based on the Fourier coefficient eight Fourier parameters can fit the shape of sagittal. The comprehensive judgment accuracy rate is 56.1%. The results showed that the otolith morphology was not significantly different between seven China stocks, while the China stocks showed a large sagittal morphological difference from the Japanese stock. It could be related to environmental factors and geographical conditions in various sea areas.
Determinants of Organizational Commitment among Academics of HEIs: The Buffering Role of Coworker Support
Authors: Ahmad Ashfaq , Bilal Hazrat , Bibi Palwasha
Published: March 2021

The significance of retaining committed staff is a main focus in contemporary literature in higher education. This study seeks to address issues related to lower employee commitment through a Social Exchange Theory Lens to explore the buffering role of co-worker support on the relationship between Supervisory Support (SS), Organizational Climate (OCL) and commitment HEIs in the Public Sector Pakistan. A quantitative and cross approach to survey was adopted as a survey technique by 366 respondents using a proportionately stratified random sampling method. The research theoretically argues and empirically shows that SS and OCL have a direct relationship with organizational commitment in the public sector HEIs. The findings suggest the significant role of SS, the organizational climate and the commitment to higher learning in the public sector. In addition, the findings confirm the hypothesis regarding the buffering effect of co-workers' help in the relationship between SS, OCL and organizational commitment. The main contribution concerns the implementation of co-worker support as a moderator between the relationship SS, OCL and the OC. The study also leads to a better understanding of the mechanisms of the organizational commitment seen in HEIs with regard to the buffering role of co-worker support in the Pakistani context.
Integrazione VS decostruzione nelle collaborazioni degli artisti visivi con la tv e qualche nota su Foligno ’67 di Alfredo Di Laura
Authors: Gallo Francesca
Published: March 2021

The contribution gives an overview of the way visual artists have intervened in television production and within its specific audiovisual languages. Against the background of some famous and prolonged international experiences, the reflection focuses on Italian television between the 1960s and 1970s. Integration, experimentation, deconstruction are some of the categories in which such interventions can be steal, in relation to the way in which painters, sculptors and multimedia artists have intended to relate to tv, on the one hand attracted by the communicative and technological potential of the medium, and on the other critical of that type of visual universe and cultural offer in general. In the same position is also placed Alfredo Di Laura, television director and author of the program Avanguardie ‘60: a particularly representative case study both as an innovative reading of the seminal contemporary art exhibition, Lo spazio dell’immagine, and for the marginalization in the schedule. The intent of the contribution, moreover, is also to underline the ineffectiveness of critical formulations that in assimilating television to electronic technology tout court absorb peculiar formal exercises, born in dialectic with the pervasive means of mass communication, within the wider history of video art.

Published: March 2021

In order to achieve high profit in agricultural crops, it is necessary that fertilization of the soil is carried out properly, avoiding over fertilization, which contributes to the sustainable management of the soil. The objective of this study was to evaluate the effect of organic fertilization with bokashi, penergetic and boiled chicken manure doses on the production and nutrient content of berries, leaf chlorophyll index and soil microbial biomass in strawberry cultivation. The experiment was conducted in protected cultivation, evaluating productive variables (individual weight of berries and total production per plant), nutrients of the berry (nitrogen, phosphorus and potassium), soil (carbon of microbial biomass) and chlorophyll index in sheets. The treatments were strawberry without fertilization (control), penergetic (1.5 g.L-1), bokashi (50 g per plant) and doses of boiled manure via fertigation (2.5; 5; 7.5 and 10%, diluted in water) in a completely randomized design with five replications. Strawberry plants fertilized with bokashi showed significantly higher means of berry biomass, total berry production per plant, leaf chlorophyll and carbon values of soil microbial biomass. Doses of 7.5 and 10% of boiled poultry manure provided berries production similar to bokashi and both were superior to the control. Higher levels of nitrogen, phosphorus and potassium were found with bokashi treatment and treatments with EF 7.5 and 10% obtained higher averages for phosphorus content in berries, only.

Perceptions of Medical Librarians Towards the Importance of Information Literacy Skills
Authors: Ullah Midrar , Ameen Kanwal
Published: March 2021

The purpose of this study was to find out medical librarians' perceptions towards the importance of information literacy (IL) skills. A structured questionnaire, consisting of eight IL skills, was administered to the head librarians of all academic medical institutions in Pakistan. The respondents were asked to rate the importance of IL skills for their users on a 5-point Likert scale (1- Least important to 5-Most important). A total of 69 (60.5 %) usable questionnaires were returned out of 114 disseminated to the respondents. The IL skills about “accessing the needed information effectively and efficiently”, “identifying relevant, authoritative and reliable information sources”, “recognizing the need for information”, "verifying the relevance and quality of information sources” and “using information ethically and legally” got mean scores exceeding four from head librarians of both public and private sector medical institutions. However, IL skill "evaluating the information critically” received mean score less than four i.e., 3.94 from public sector medical librarians and IL skills "organizing information collected or generated in a logical way" and "using the selected information effectively to accomplish a specific task" although considered important but got lower mean scores (3.97 each) from private sector medical librarians. Respondents from both public and private sector medical institutions had considered all the eight IL skills important for their library users, meaning that library users must be adequately equipped with information competencies.

This research aims to investigate the contemporary situation of ‘cyber-ethics’ that is prevailing among the users of the internet. The cyber world seems to be a second or virtual world for all of those who use the internet. Three diverse perspectives of cyber-ethics, i.e. Professional, Philosophical and Descriptive give a better understanding of how different philosophers, social scientists and even computer professionals view cyber-ethics and how the advancement in the field of technology can be embedded into the social system. Along with the advantages of being ‘connected’ to the world at large, it also brings some disadvantages on the ethical side and it is no astonishment that Pakistan is also not liberated from the cyber space dilemma. A survey was conducted in four major universities of Islamabad in order to measure the perception of internet users regarding the concept of ‘cyberethics’. The survey was carried out on 304 respondents (152 males, 152 females) and a detailed questionnaire was used as the prime tool of the survey method. Although the perception of male and female students differ from each other in various regards (as supported by the Ethical Theory of Relativism), the results reveal that there is a positive attitude of respondents towards the main concept of cyber-ethics on the whole, but there is still a long way to go in order to obtain a better understanding and to adopt the proper ways of using cyber technology.

- This study aims to build a decision support system that can help facilitate the selection of the right used car for potential buyers. To be able to buy a used car that suits the needs and funds owned by consumers, buyers must consider the many criteria and factors of each used car which consists of various brands that exist today. This study uses the ELECTRE (Elimination and Choice Translation Reality) method. The criteria in the comparison used in this decision support system are documents, cylinder volume, year of production and car price. The ELECTRE method is used in conditions where alternatives that do not meet the criteria are eliminated, and suitable alternatives can be generated. Of the 8 samples of used cars studied, the best recommendation was Ayla (A4) with a total aggregate of 4 and an alternative that was not recommended was Agya (A3) with a total aggregate of 0.

La necesidad de adquirir alimentos de forma adecuada y sana ha llevado a buscar y fortalecer alternativas para su producción; en las ciudades se practica la agricultura urbana y periurbana (AUyP) y Xalapa, Veracruz, México, es un ejemplo de ello. Desde el año 2013 se autogestiono la Red de Agricultura Urbana y Periurbana de Xalapa (RAUPX), en la cual se centró el objetivo de la presente investigación, que consistió en caracterizar los huertos de la RAUPX, en función de las variables: tamaño de huerto, diversidad (índice de Shannon), presencia de artropofauna y prácticas de manejo fitosanitarias; con el fin de diagnosticar y aportar propuestas para mejorar el manejo integrado de plagas. Los resultados incluyen datos generales productor-huerto tales como rango de edad, nivel de estudios, superficie, familias botánicas representativas, presencia de artropofauna en relación con las especies cultivadas y manejo de prácticas fitosanitarias de acuerdo con su complejidad. Las prácticas fitosanitarias que realizan los productores son de forma correctiva en vez de preventiva y están moderadamente relacionadas con la presencia de plagas.

Yönetim yazınında son zamanlarda incelenen konulara bakıldığında, bireyleri belirlenmiş amaç ve hedefler doğrultusunda harekete geçirme yeteneği olarak ifade edilen liderlik kavramı ile bu becerilerin tür ve kaynağını belirleyen liderlik stillerinin çalışmaların odağı haline geldiği görülmektedir. Bu kapsamda liderlik kavramı çerçevesinde en çok dikkate alınan ve incelenen konuların örgütlerde baskın liderlik tarzı ve algıları, liderlerin çalışanlarla etkileşimi, örgütlere yapısal ve işlevsel katkıları, güç kaynakları ve güç kullanımına ilişkin kararlar olduğunu söylemek mümkündür. Son zamanlarda kültür kavramının da birçok örgütsel davranış konusu ile ilişkisi ele alınmaktadır. Çünkü kültür paylaşılan, öğrenilen ve değişebilen bir kavram olarak insan davranışları üzerinde etkilidir. Ayrıca değişimi yöneten ve insanları hedefe yönlendiren liderlik kavramı ile ilişkisinin olduğu da ifade edilebilir. Fakat alan yazında, liderlik ve kültür arasındaki ilişkilerin araştırılmasına çok yakın zamanda başlandığı söylenebilir. Bu bağlamda bu çalışmanın amacı, ulusal kültürel boyutlar ile çalışanların paternalist liderlik algısı arasındaki ilişkiyi ampirik olarak ele almaktır. Çalışmanın örneklemini verilerine eksiksiz ulaşılan Libya’daki 200 banka çalışanı oluşturmaktadır. Elde edilen verilerin toplanmasında basit tesadüfi örnekleme yöntemi kullanılmıştır. Veriler anketler aracılığı ile elde edilmiştir. Elde edilen verilerin incelenmesi için keşfedici faktör, korelasyon ve regresyon analizlerinden faydalanılmıştır. Geçekleştirilen regresyon analizleri sonucunda; ulusal kültür boyutlarının, paternalist liderlik algısı ve alt boyutları üzerinde kısmi etkisinin olduğu tespit edilmiştir.

Published: March 2021

Purpose

This study analysed the influence of the absence of goalkeeper and the number of goals in tactical actions in 3 configurations of small-sided and conditioned games (SSCGs): (a) goalkeeper + 3 vs. 3 + goalkeeper; (b) 3 vs. 3 (no goalkeeper); and (c) 3 vs. 3 with 2 mini goals.

Methods

Overall, 24 under-15 soccer players were divided into 8 teams of 3 players each. Seven games were played for each configuration for a total of 21. The tactical behaviour was evaluated with the System of Tactical Assessment in Soccer (FUT-SAT).

Results

More offensive actions were performed in the SSCGs with goalkeepers. The games played without goalkeepers led to more actions associated with defensive unity but also a higher rate of errors concerning the tactical principles of delay and defensive unity. In relation to the outcome of actions, more fouls, throw-ins, and corner kicks were observed in the SSCGs with 2 mini goals.

Conclusions

The games played without goalkeepers reflected a higher difficulty in managing spaces of the game and led to a higher number of errors in the performance of core defensive tactical principles. In the games played with 2 mini goals, it was observed that the players on the wings were positioned closer to each other, which made the play more fragmented compared with the other conditions. In accordance with these results, it is possible to identify the influence of goalkeepers on tactical behaviour during SSCGs.
