For the last several decades, psychologists have been paying attention to the changes in the Polish family model and the transformation of the father’s role within it. These are the processes that were also significantly affected by the COVID-19 pandemic. The objective of the research was to understand how the Polish young men awaiting the birth of their first child experience fatherhood in this time of crisis. Seven semi-structured interviews were conducted with men aged 26–35. Their transcripts were subject to Interpretative Phenomenological Analysis (IPA). The results showed that the pandemic took away the opportunity to act in areas that were previously available to fathers from the participants. At the same time, the pandemic gave them new areas where they could fulfil themselves as fathers. Despite the limited access to prenatal care services, participants got a chance to be more present in their unborn child’s life. Moreover, they got a chance to be more active at the stage of waiting for their birth.

Suppressing negative emotions (anger, fear, sadness) can lead to an increase in emotional tension. Unexpressed emotions contribute to the deterioration of health and may also contribute to the emergence of psychosomatic disorders and certain diseases, such as coronary artery disease, hypertension, and cancer. Research shows that depressive emotionality is associated with lower self-esteem while lowering life quality and life satisfaction. The aim of the study was to analyze whether suppressing negative emotions is related to the level of self-esteem amongst young mothers and their satisfaction with life, as well as to identify mediators that determine the quality of this relationship. 340 young mothers (mean age 30.09) were examined. To conduct the research the Emotional Control Scale – CECS in its Polish adaptation of Zygfryd Juczyński, the Life Satisfaction Scale by Zygfryd Juczyński and the SES Self-esteem Scale adapted by Mariola Łaguna, Kinga Lachowicz-Tabaczek and Irena Dzwonkowska were used. The analyses confirmed the existence of significant relations between the level of suppressing negative emotions (sadness and anxiety) and self-esteem as well as life satisfaction. It also turned out that the level of self-esteem is an important mediator in the relation between the suppression of sadness and anxiety by young mothers and their satisfaction with life.

Abstract INTRODUCTION: During university life new routines and life-styles are adapted into conduct, which can associate to unfavorable changes in food consumption, alimentary-risk conducts (CAR) associated with alimentary-conduct disorders (TCA), sedentary life-style and restrained physical-activity (AF), which promote weight-gain and have repercussions on the body-mass index (IMC), enhancing the prevalence of overweight and obesity in such population. Objectives: The main objective for this study was to determine the association between the alimentary intake, CAR, AF, sedentary life-style and IMC in college students from Hidalgo state. MATERIALS AND METHODS: Transversal analytic study in a probabilistic sample of 378 students of both sexes, ranging from 18 to 30 years old in Hidalgo, México. The frequency of food consumption, TCA-risk, sedentary lifestyle, and AF were measured by the means of previously validated and standardized scales. The patient’s IMC was calculated from self-reports. RESULTS: TCA-risk was slightly higher in women (38.1%) than in men (29%), nonetheless the difference was not significant. The consumption of certain food-groups presented a significant difference by sex, TCA-risk and AF class. 31.7% of the sample registered a sedentary life-style, with men exerting more AF than women. The sampled population reached a total prevalence of 28% of overweight/obesity. CONCLUSION: Overweight/obesity increased 2.19 times the risk for developing a TCA in the overall population. In women, this condition increased 3.27 times the risk. It was observed that female sex is a protective factor (in 64% of the cases) to develop overweight/obesity (RM= 0.36, p<0.01).
Reflections on Decolonising of Medium of Instruction at South African Universities
Authors: Mutongoza Bonginkosi Hardy , Mutanho Chrispen , Linake Manthekeleng Agnes , Makeleni Sive
Published: September 2023

The 2015/6 #Rhodes Must Fall student protest reignited the debate to decolonise higher education in South Africa and many parts of the world. One way of achieving this is through decolonising the language of teaching and learning in higher education to increase access. Within this caveat, we anticipate that this article will add a crucial contribution to contemporary international and local debates on decolonising the medium of instruction by providing evidence from South African institutions’ unique challenges and prospects associated with the quest to deliver quality decolonised education. While tremendous strides have been made in expressing the constitutional right of every learner to receive primary education in a language of their choice, at the university level, the development and implementation of inclusive language policies have been dismal at best. With the demise of the apartheid regime that significantly stifled African languages in South Africa, one could have hoped for changes in attitude and language usage in universities, mainly because universities still have discernible remnants of the apartheid legacy. This article highlights the urgent need for decolonising South African higher education, particularly concerning using English as the medium of instruction. We further hope that this study will benefit practitioners and stakeholders involved in formulating language policies at their respective learning institutions and prompt them to treat the decolonisation process with befitting urgency.
Developing a Media Literacy Perception Scale
Authors: Özel Aykut
Published: September 2023

The purpose of this research was to develop a scale to determine the perceptions of media literacy. For this purpose, trial forms have been created and submitted for expert opinion. The scale items were revised based on the feedback received after the trial forms were examined about the content validity according to expert opinion. A pilot study was conducted with a sample group with characteristics similar to the general population in order to assess the construct validity, sub-dimensions, and reliability level of the draft scale, which was finalized after expert opinions were obtained and appropriate revisions were made. The working group of the pilot study was composed of students selected apart from the research sample. In order to reach the students, the “Simple Random Sampling” method was used. The construct validity of the scale was tested by performing factor analysis (EFA + CFA). To determine the reliability of the scale, item-total score correlations and Cronbach’s alpha internal consistency coefficient values were used.

Since several items had low item-total test correlations and some items had loadings for two distinct variables that were close to one another, these items were gradually excluded from the study until there were no extreme values present in the analysis and statistical errors were eliminated. Validity analyses (EFA + CFA) and Reliability (Cronbach’s alpha) of the obtained data were performed and the statements were finalized and the “Media Literacy Perception Scale” (MLPS) consisting of 16 items and three dimensions (factors) was created. The Cronbach’s alpha coefficient for the entire scale in this research was found to be .86.

Published: September 2023

University stakeholders are a united entity; whenever one party does not hold up their end of the deal, it eventually becomes a challenge for all the stakeholders. In this case, universities that are struggling to retain lecturers pose a challenge to the universities’ goodwill. Accordingly, this study examines factors influencing lecturers’ retention in a South African university, and the guidelines for the universities to enhance lecturer retention policies are investigated. Herzberg’s two-factor theory was adopted as the theoretical framework for the study. The qualitative research approach was adopted within the Transformative paradigm using Participatory case study as a research design. A total of 14 participants were selected using a purposive sampling method amongst a pool of university stakeholders. As a result, semi-structured interviews were conducted, and the data was analysed using thematic analysis. The study found that less promotional opportunities and less recognition are factors influencing lecturers’ retention in a South African university. In addition, flexible work arrangements together with the promotion of teamwork, were suggested as guidelines for universities to enhance lecturer retention. Therefore, promoting deserving lecturers, counteroffers, recognising hard-working lecturers, flexible work schedules and promoting teamwork are the recommendations to transform retention problems in universities.

Authors: Ntuli Lesheleba Tiny , Mahlangu Vimbi Petrus
Published: September 2023

In terms of curriculum management in primary schools, the study's main goal was to examine the roles and experiences of school management teams (SMTs). Therefore, it was intended to look at the functions of SMTs as instructional leaders. A qualitative research strategy was adopted, and data were gathered through non-participant observation, individual interviews, focus groups, and document analysis. The participants' meanings of their lived experiences were described using the interpretivist paradigm. The management of curriculum implementation was viewed through the lenses of instructional leadership and traditional management ideas. SMTs, or participants with plenty of information, were chosen through purposeful sampling. It was discovered that the SMTs must apply both management and leadership constructs to manage the execution of the program effectively. Ineffective management and leadership prevent effective teaching from taking hold in classrooms. For schools to be effective, leadership and management must be of a high calibre. Additionally, it was discovered that while SMTs were able to recognize their tasks, some of them lacked expertise in managing the execution of curricula.   Only primary schools were examined, and the study mostly relied on the opinions of the SMTs, which include the principle, deputy principal, departmental heads, subject heads, and senior teachers.

The aim of this research is to reveal the relationship between the life satisfaction of mothers and the happiness-increasing strategies they use for their children. Within the scope of the general purpose of the study, it was also examined whether the life satisfaction of the mothers and the happiness-enhancing strategies they used for their children differed in terms of some demographic variables. The correlational model, one of the quantitative research designs, was used in the study, and the sample group consisted of 298 mothers with children aged 3-5 years. A Demographic Information Form, a Scale for Determining Happiness-increasing Strategies Used by Mothers, and a Life Satisfaction Scale were used as data collection tools. In the research; t test and single-factor analysis of variance (ANOVA) were performed for independent samples with differentiation tests to examine the differences between the life satisfaction levels of the mothers and the happiness-increasing strategies they applied according to variables such as education level, economic status, and working status.  Pearson moments multiplication correlation analysis was performed to examine the relationship between mothers' life satisfaction levels, happiness-increasing strategy levels, age of mothers, and child age, and multiple linear regression analysis was performed to determine the predictive power of the independent variable (happiness-enhancing strategies) to the dependent variable (life satisfaction). At the end of the research, it was concluded that the level of life satisfaction increased as the education level and economic status of the mothers increased, and the levels of happiness-increasing strategies showed a significant difference according to the economic status. It was seen that there was a significant relationship between the life satisfaction levels of the mothers and the strategies to increase happiness. Recommendations were developed in line with the findings obtained as a result of the research.

Crime is behavior that violates the law and social norms so that people oppose it which can occur due to environmental factors, namely the imitation of criminality and individual economic factors, can be prevented by criminal policies, and can increase in certain situations, one of which is the economic crisis. The mathematical model of the spread of crime is built by considering individual economic factors which are implemented as work and non-work compartments, crime imitation factors which are implemented as the rate of crime affected, and criminal policy factors as an obstacle to crime. Based on the model that has been built, the equilibrium point and its stability, the basic reproduction rate, population dynamics, and conditions that can describe the influence of criminal policy and the economic crisis on the crime rate are determined. The model has one non-endemic equilibrium point and one non-negative endemic equilibrium point which can reach a stable condition. Numerical simulations show that population dynamics using parameter values and initial compartments obtained from various sources are stable towards an endemic equilibrium point, criminal policies can reduce crime rates, and economic crises can increase crime rates.

Infectious diseases are a problem that is still a challenge and has not been resolved in Indonesia. The number of infectious disease cases continues to increase every year in Indonesia. Infectious diseases that are still a problem in Indonesia include tuberculosis (TB), pneumonia and leprosy (Leprosy). Identification of infectious disease endemic areas is an important issue in the health sector, the average rate of people with physical disabilities and deaths originating from infectious diseases. Indonesia, as a country consisting of 34 provinces, including East Java as one of the provinces that has a high rate of infectious disease cases. Therefore, research was conducted using correspondence analysis which aimed to determine the pattern of infectious disease trends and grouping districts / cities in East Java Province based on similarities between the spread of disease sufferers in each district / city. This type of research uses quantitative methods with secondary data obtained from the Central Bureau of Statistics of East Java Province. The results of correspondence analysis show that  the spread of pneumonia and tuberculosis in East Java  Province has a relative tendency to almost all regencies/cities in East Java, while the spread of leprosy is closer to Sampang Regency. From this research, it can be used to supervise and control infectious diseases in districts / cities in East Java Province, so that the government can adjust policy formulation and actions to prevent an increase in infectious disease cases in East Java

Investment is one of the development factors in economic activity, there are two basic things that investor must know before making investment decisions, namely: returns and risk. One of the statistical methods to calculate the maximum loss in investment is Value at Risk (VaR). this study aims to calculate VaR on the closing stock price data of Pt. Gudang Garam TBK for the daily period starting from 4 January 2021 to 30 December 2021. Log return data is model by ARIMA. The ARIMA model contains a heteroscedasticity effect so it is inadequate for modelling, one of the models that can overcome the heteroscedasticity problem is the ARCH-GARCH model. Forecasting the volatility of the data is done using the ARCH-GARCH model. The results show that the GARCH (1,1) is the best model for predicting volatility. Volatility is predicted for the next 30 days, after the volatility forecasting results are obtained, the VaR calculation can be continued. Based on the results, it shows that volatility increases over time, which means that the risk that investor will accept will be higher and the returns will also be greater
