Moderasi Beragama Muhammadiyah dalam Kajian Kesarjanaan Indonesia: Antara Studi dan Dakwah Islam
Authors: HS Muhammad Alwi
Published: January 2022

Artikel ini membahas kajian sarjana Indonesia terkait moderasi beragama yang digaungkan oleh Muhammadiyah dengan mengarah pada pemetaan apakah kajian sarjana tersebut bernuansa studi Islam atau dakwah Islam. Data-data kajian sarjana diperoleh dari artikel jurnal yang dipublikasikan sejak edisi pertama 2016 hingga edisi kedua 2020. Melalui metode deskritpitf--analitis, artikel ini menyimpulkan bahwa kajian-kajian sarjana Indonesia cenderung berkisar pada kajian bernuansa dakwah daripada studi. Artinya, para sarjana Indonesia cenderung menjadi perpanjangan tangan atas pemahaman dan gerakan moderasi beragama untuk konteks Indonesia. Semua latar belakang isu moderasi beragama dalam kajian sarjana Indonesia tersebut berdasarkan kegelisahannya menyaksikan fenomena radikalisme, terorisme, dan aksi ekslusif lainnya, yang secara riil membutuhkan solusi, termasuk dari perspektif Muhammadiyah. Temuan ini menunjukkan bahwa sisi teologi Islam yang melekat pada kesarjanaan senantiasa mempengaruhi kajiannya. Sehingga, sekalipun posisi sarjana Indonesia berada di ruang akademisi, yang menempatkan dan menuntut mereka sebagai peneliti, tetapi para sarjana tersebut tidak dapat dilepaskan dari identitasnya sebagai penganut agama Islam, yang yakin akan kebenaran agamanya dan bertujuan menyebarkannya, termasuk dalam hal moderasi beragama menurut ORMAS Islam Indonesia.

Authors: ASLAN Asiye
Published: January 2022

Data on exterior temperature constitute one of the most important parameters in the calculation of energy needs in buildings. This study obtained the temperature distribution curves by analyzing the outdoor air temperature in Bandırma. Heating Degree Hour (HDH) and Cooling Degree Hour (CDH) for three different base temperatures were calculated. A 21-year data set between 2000-2020 obtained from the General Directorate of Meteorology was used. The incidence (%) of outdoor air temperature according to months was determined. In the calculation of the HDH and CDH values, base temperatures of (15, 18 and 20 °C) and (20, 22 and 24 °C) were considered respectively. The results of the analysis showed that the number of HDH changed between 31357 and 53037, while CDH numbers ranged between 10433 and 2669. The increase in the average outdoor air temperature with the effects of global warming was determined for heating and cooling season in a 21-year period according to year. It was determined that there was an increase of 1.68 °C in the heating season in the 21-year period and 1.80 °C in the cooling season in the 21-year period. In this study, the necessity of determining energy needs for heating and cooling purposes in a clear and up-to-date manner was emphasized once again. This is highly important to not only achieve energy savings but also reduce the air pollution effects of energy consumption. It is believed that this study will make a contribution to the literature in this sense.

Published: January 2022

Spiritual well-being is a deep feeling within the mind that represents peacefulness and the inner strength of individuals, resulting from an understanding of the nature of life and acceptance of changes occurring to themselves. Spiritual well-being is; therefore, very important to dependent older people. The objectives of this study were to identify the levels of spiritual well-being of dependent older people, to examine the relationships between religious belief, religious practice, self-esteem, social support, depression, and spiritual well-being, and to examine the ability of those factors to predict spiritual well-being among dependent older people. The study sample were 395 of people aged 60 years and above who are dependent and live in three provinces in southern Thailand. Data were collected using questionnaires, including the Spiritual Well-Being Scale for Dependent Older People, Thai version of the Rosenberg Self-Esteem Scale, Thai version of the Multidimensional Scale of Perceived Social Support, Thai Geriatric Depression Scale, the Religious Practices Questionnaire, and the Buddhist Belief Questionnaire. Data were analyzed using descriptive statistics, Spearman’s rank correlation coefficient, and multiple regression analysis. The study results were as follows: 1) The spiritual well-being among dependent older people was at a moderate level (x̅ = 46.97, SD = 7.22). 2) Religious belief, religious practice, self-esteem, and social support significantly related positively to spiritual well-being (p < 0.01), while depression significantly related negatively to spiritual well-being (p < 0.01). 3) Religious belief, self-esteem, and social support together could explain 46.00 % of the variance in spiritual well-being. The results of this study can be used by nurses and health care providers to determine interventions for enhancing spiritual well-being in this particular group of older people.

Since the building made of cement concrete consumes almost half of the total energy generated and accordingly accountable for huge amount of CO2 emission, it is necessary to replace the Portland cement (PC) with sustainable construction material. Similarly, Prosopis Juliflora is a shrub or small tree in the family Fabaceae, a kind of mesquite which is considered to be a potential threat for ground water in South India. Hence, this has to eradicate so as to maintain the groundwater and also to effectively utilize its ash thereby reducing environmental pollution, this can be used as a partial replacement for cement. In this regard, this paper investigates the technical feasibility of using Prosopis Juliflora ash (PJA) as cementitious material by partially (5%, 10% and 15%) replacing cement by Prosopis Juliflora ash. The mixes were evaluated for their fresh, physical and strength properties such as workability, density and compressive strength and the results were compared with the conventional mix. In order to save the environment and to save the resources we have come up with using the Prosopis Juliflora (Semai-Karuvelam in Tamil) ash as the partial replacement of cement. Cement will produce equal amount of greenhouse gas (co2) which increase the global warming. As the amount of cement is reduced greenhouse gases also reduced. Utilization of Juliflora ash as a partial substitution for cement is one of the promising methods to increase the strength and thermal insulation for cement blocks. The strength parameters (compressive strength, split tensile strength and flexural strength) of concrete with blended Prosopis Juliflora cement are evaluated.

Individual’s genetic makeup best describes the properties regarding its growth and development. It is stored and passed on to generations and is in dynamic equilibrium with the environmental and other non-living factors. The most predominant environmental stimuli are diet/nutrition.  Diet/nutrition interacts and modulates varying underlying molecular mechanisms central to various physiological functions basically at three different levels: genome, proteome, and metabolome. Advances in genomic studies are paving the way to the development of scientific insights into nutritional sciences. Nutrigenetics and nutrigenomics are closely associated but two different areas of nutritional research. Both the fields involved the study of the implication between nutrition, metabolism, and genetic mechanism. The primary goal is to pinpoint nutrient-dependent health characteristics and nutrition dependent diseases. Another important area connected to these sciences concerns food composition and performance of quality assessment by studying proteomics and metabolic pathways. Nutrigenomics explains how the nutrients influences or effects the expression of the, while the response of different gene variants to nutrients or different dietary components is called Nutrigenetics. A personalized based diet can help us to know the right nutrient to take or avoid those who may potentially harm overall health. The goals are intended to alter or decrease the impact of hostile dietary changes that have occurred in since past in the developed world and more recently in the developing countries.

Introduction: Due to lack of PCR kits in our area, as well as the extensive dissemination and peaking of COVID-19 since March 2020, our knowledge as radiologists has become increasingly relevant for recognizing CT patterns in order to diagnose and isolate COVID-19-infected patients. In 100 instances, the investigation began with the most prevalent CT chest abnormalities and the CT severity score index in relation to sex. The goal of this study is to better diagnose COVID-19-related lung injuries, enhance the diagnostic accuracy of chest CT scans, and track disease development in Mosul City.
Materials and Methods: From June 2020 to January 2021, one hundred patients were enrolled in this cross-sectional study in Mosul, with 71 males (71%) and 29 females (29%) ranging in age from 15 to 85 years, mean SD (53.2317.80). Non contrast chest CT were done as part of investigation tool on patients were suspected COVID-19 infection.
Results: A radiologist gathered data between 4 and 10 days after the onset of symptoms and evaluated it for lesion pattern, location, and severity. The commonest CT changes (ground glass opacity 55.23%, consolidation 17.44%, broncho vascular thickening 9.88%, crazy paving 5.81% and tree in bud 5.23%) were seen, along with less common pattern (bronchiectasis 1.74%, nodules 2.33%, reversed halo sign and pleural effusion 1.17%), and no lymphadenopathy were seen.  Multilobe involvement was detected in 52/100 instances (68.92%), while peripheral affection was seen in 52/100 cases (65%). The higher CT severity score 4 and 5 with male gender were found to have a significant link (P value 0.002).
Conclusion: CT pulmonary are useful as a physician's helper for management and as an excellent predictor of disease severity and patient outcome. In patients with COVID-19 positive infection, the CT scan severity score is highly linked to laboratory findings, hospital stay, and oxygen demands.

Published: January 2022

Introduction and Aim: Neonatal seizure is an age specific neurological emergency. Their unique pathophysiological mechanism has become subject of interest for many research studies. The recurrence risk for seizures is high during neonatal period and currently used treatment strategies have limited efficacy in preventing it. From past decades although the treatment has not changed, there is a gradual progress in various mechanisms that are involved in generation of seizures and their response to anti-epileptics. With the emergence of new biochemical parameters for risk assessment in patients with seizures, there is a strong need for their comparative evaluation in order to evaluate their potential clinical application. So, this study was carried out to compare the urine levels of taurine, dopamine and fucose in assessing their role in mechanism of seizure.
 
Materials and Methods: After obtaining ethical approval and consent from parents total 43 neonates, urine taurine, dopamine and fucose were measured in 24 cases of seizures and 19 apparently healthy normal controls. Dopamine and Taurine were measured using ELISA and L-fucose by Dische and Shettles method.
 
Results: The median level of urine fucose was significantly higher in male neonates, taurine was significantly decreased in cases compared to that of controls. Males had higher preponderance to develop seizures. The median levels of urine dopamine were high in cases compared to controls but has not showed any significance.
 
Conclusion: Amino acid like taurine, carbohydrate moiety like fucose and a neuromodulator like dopamine may have a mechanistic role in development of seizures in neonatal period.

Published: January 2022

The vasculature of the placenta plays a crucial role during the course of pregnancy in order to maintain the growing need of the fetus. Abnormal placental structure and function significantly increase the risk of stillbirth. Various growth factors and cytokines play an important role in the vasculogenesis and angiogenesis of placenta. These processes are stimulated by various pro-angiogenic factors. The activities of these factors are also stimulated by hypoxia. In some of the physiological phenomenon like ovulation, embryogenesis as well as in wound healing intense blood vessel growth can be seen similar to that seen in placenta. Therefore, factors that induce and maintain placental vascular growth and function are of considerable developmental and clinical significance. The total arterial architecture may also depend upon the pro-angiogenic factors. Hormones and other growth factors are other contributors of this vasculogenesis and angiogenesis. Any dysfunction of factors can lead to foetal hypoxia and related complications. This review describes the major growth factors and their significant role in vasculogenesis and angiogenesis of placenta.

Authors: Pramana Putu Yogi , Yudha Anak Agung Gede Kesuma
Published: January 2022

The development of health science, with the discovery of a type of treatment to reduce mortality due to cancer, namely using chemotherapy agents such as anthracycline and trastuzumab. From the number of studies that have been done, the types of drugs such as anthracycline and trastuzumab have a cardiotoxic effect which is often associated with decreased heart-lung function and the incidence of cardiomyopathy. Exercise is reported to have a pleiotropic effect. Therefore, this study aims to synthesize evidence from the application of pleiotropic exercise in cancer patients undergoing chemotherapy with cardiotoxic agents. The search was performed according to the recommended reporting items for systematic review and meta-analyses (PRISMA). Obtained an accumulation of 2397 articles from PubMed and Google Scholar (2016-2020), which were assisted by the PICO search engine. The article was reviewed by the author within sorting using inclusion and exclusion criteria and obtained 28 articles accordingly. Aerobic exercise has pleiotropic effects by stimulating antioxidants and reducing reactive oxygen species (ROS) levels, reducing pro-apoptosis molecular signaling, stimulating myofilament, facilitating concentric cardia hypertrophy remodeling, and changing cardiac metabolism via adenosine monophosphate (amp) with kinase-mediated. Pretreatment aerobic exercise with minimal supervised 30-min exercise sessions 3 times/week for ≥12 weeks effectively reduce the risk of chemotherapy-induced cardiomyopathy (CRC). Aerobic exercise has a significant pleiotropic effect in patients undergoing chemotherapy with cardiotoxic agents.
¿Movimiento humano o motricidad humana? Análisis de algunas perspectivas filosóficas
Authors: Mujica Johnson Felipe Nicolás
Published: January 2022

Las ideas filosóficas del ámbito de la actividad física suelen estar sustentadas en concepciones que trascienden la propia disciplina de estudio aludida, de modo que es importante estudiarlas en profundidad. Este ensayo tiene por objetivo comprender la interpretación de los términos movimiento humano y motricidad humana desde la mirada de tres corrientes filosóficas que han sido utilizadas por referentes de la actividad física, el deporte y la Educación Física. La primera corriente filosófica analizada es la de corte idealista, que entiende el movimiento humano como un acto esencialmente mecánico y biológico. La segunda perspectiva filosófica es la materialista, que entiende el movimiento humano como una manifestación de la motricidad, la cual sería inmanente a la esencia del ser humano. Es decir, estaría dotada de intencionalidad. La tercera corriente sería una mirada ecléctica de las dos anteriores, asemejando el concepto de movimiento humano con el de las contemporáneas interpretaciones de motricidad. En otras palabras, el movimiento humano sería parte de la potencia y el acto. Se concluye que, según diferentes perspectivas filosóficas, es posible utilizar el concepto de movimiento y/o motricidad para trascender la mirada idealista o moderna del movimiento humano.
Marx según Marzoa

Published: January 2022

El sentido de este artículo es el de mostrar, mediante del análisis de la obra principal de F. M. Marzoa, cómo incluso a través de los autores que con mayor rigor enfrentan la lectura de la obra de Marx, se filtra, de diversos modos, parte del material conceptual alienado que constituye la ideología, así como versiones tópicas de determinadas desviaciones del pensamiento marxiano. Lo que vale para Martínez Marzoa (quien, a juicio del autor del presente artículo, es uno de los mejores intérpretes de Marx) vale, también, para Althusser, en parte para la “escuela de Frankfurt” y otras corrientes postmodernas.
Aerosol Atmospheric Rivers: Climatology, Event Characteristics, and Detection Algorithm Sensitivities
Authors: Chakraborty Sudip , Guan Bin , Waliser Duane , da Silva Arlindo
Published: January 2022

Abstract. Leveraging the concept of atmospheric rivers (ARs), a detection technique based on a widely utilized global algorithm to detect ARs (Guan et al., 2018; Guan and Waliser, 2015, 2019) was recently developed to detect aerosol atmospheric rivers (AARs) using the Modern-Era Retrospective analysis for Research and Applications, Version 2 reanalysis (Chakraborty et al., 2021a). The current study further characterizes and quantifies various details of AARs that were not provided in that study, such as AARs’ seasonality, event characteristics, vertical profiles of aerosol mass mixing ratio and wind speed, and the fraction of total annual aerosol transport conducted by AARs. Analysis is also performed to quantify the sensitivity of AAR detection to the criteria and thresholds used by the algorithm. AARs occur more frequently over, and typically extend from, regions with higher aerosol emission. For a number of planetary-scale pathways that exhibit large climatological aerosol transport, AARs contribute 40–80 % to the total annual transport. DU AARs are more frequent in boreal spring, SS AARs are often more frequent during the boreal winter (summer) in the Northern (Southern) Hemisphere, CA AARs are more frequent during dry seasons and often originate from the global rainforests and industrial areas, and SU AARs are present in the Northern Hemisphere during all seasons. For most aerosol types, the mass mixing ratio within AARs is highest near the surface and decreases monotonically with altitude. However, DU and CA AARs over or near the African continent exhibit peaks in their aerosol mixing ratio profiles around 700 hPa.

Abstract. After the successful launch of Aeolus, which is the first
spaceborne wind lidar developed by the European Space Agency (ESA), on 22 August 2018, we deployed several ground-based coherent Doppler wind lidars
(CDLs) to verify the wind observations from Aeolus. By the simultaneous wind
measurements with CDLs at 17 stations over China, the Rayleigh-clear and
Mie-cloudy horizontal-line-of-sight (HLOS) wind velocities from Aeolus in
the atmospheric boundary layer and the lower troposphere are compared with
those from CDLs. To ensure the quality of the measurement data from CDLs and
Aeolus, strict quality controls are applied in this study. Overall, 52
simultaneous Mie-cloudy comparison pairs and 387 Rayleigh-clear comparison
pairs from this campaign are acquired. All of the Aeolus-produced Level 2B (L2B) Mie-cloudy HLOS wind and Rayleigh-clear HLOS wind and CDL-produced HLOS wind are compared
individually. For the inter-comparison result of Mie-cloudy HLOS wind and
CDL-produced HLOS wind, the correlation coefficient, the standard deviation,
the scaled mean absolute deviation (MAD) and the bias are 0.83, 3.15 m s−1, 2.64 m s−1 and −0.25 m s−1, respectively, while the y=ax
slope, the y=ax+b slope and the y=ax+b intercept are 0.93,
0.92 and −0.33 m s−1. For the Rayleigh-clear
HLOS wind, the correlation coefficient, the standard deviation, the scaled
MAD and the bias are 0.62, 7.07 m s−1, 5.77 m s−1 and −1.15 m s−1, respectively, while the y=ax slope, the
y=ax+b slope and the y=ax+b intercept are 1.00, 0.96 and
−1.2 m s−1. It is found that the standard
deviation, the scaled MAD and the bias on ascending tracks are lower than
those on descending tracks. Moreover, to evaluate the accuracy of Aeolus HLOS
wind measurements under different product baselines, the Aeolus L2B
Mie-cloudy HLOS wind data and L2B Rayleigh-clear HLOS wind data under
Baselines 07 and 08, Baselines 09 and 10, and Baseline 11 are compared against the
CDL-retrieved HLOS wind data separately. From the comparison results, marked misfits between the wind data from Aeolus Baselines 07 and 08 and wind data from
CDLs in the atmospheric boundary layer and the lower troposphere are found.
With the continuous calibration and validation and product processor
updates, the performances of Aeolus wind measurements under Baselines 09 and 10
and Baseline 11 are improved significantly. Considering the influence of
turbulence and convection in the atmospheric boundary layers and the lower
troposphere, higher values for the vertical velocity are common in this
region. Hence, as a special note, the vertical velocity could impact the
HLOS wind velocity retrieval from Aeolus.

Abstract. Certain biological particles are highly efficient ice nuclei (IN), but the actual contribution of bioparticles to the pool of atmospheric IN and their relation to precipitation are not well characterized. We investigated the composition of bioaerosols, ice nucleation activity, and the effect of rainfall by metagenomic sequencing and freezing experiments of aerosol samples collected during the INUIT 2016 campaign in a rural dryland on the eastern Mediterranean island of Cyprus. Taxonomic analysis showed community changes related to rainfall. For the rain-affected samples, we found higher read proportions of fungi, particularly of Agaricomycetes, which are a class of fungi that actively discharge their spores into the atmosphere in response to humidity changes. In contrast, the read proportions of bacteria were reduced, indicating an effective removal of bacteria by precipitation. Freezing experiments showed that the IN population in the investigated samples was influenced by both rainfall and dust events. For example, filtration and heat treatment of the samples collected during and immediately after rainfall yielded enhanced fractions of heat-sensitive IN in the size ranges larger than 5 µm and smaller than 0.1 µm, which were likely of biological origin (entire bioparticles and soluble macromolecular bio-IN). In contrast, samples collected in periods with dust events were dominated by heat-resistant IN active at lower temperatures, most likely mineral dust. The DNA analysis revealed low numbers of reads related to microorganisms that are known to be IN-active. This may reflect unknown sources of atmospheric bio-IN as well as the presence of cell-free IN macromolecules that do not contain DNA, in particular for sizes < 0.1 µm. The observed effects of rainfall on the composition of atmospheric bioaerosols and IN may influence the hydrological cycle (bioprecipitation cycle) as well as the health effects of air particulate matter (pathogens, allergens).
Evaluation of the impact of active wake control techniques on ultimate loads for a 10 MW wind turbine

Published: January 2022

Abstract. Wind farm control is one of the solutions recently proposed to increase the overall energy production of a wind power plant. A generic wind farm control is typically synthesized so as to optimize the energy production of the entire wind farm by reducing the detrimental effects due to wake–turbine interactions. As a matter of fact, the performance of a farm control is typically measured by looking at the increase in the power production, properly weighted through the wind statistics. Sometimes, fatigue loads are also considered in the control optimization problem. However, an aspect which is rather overlooked in the literature on this subject is the evaluation of the impact that a farm control law has on the individual wind turbine in terms of maximum loads and dynamic response under extreme conditions. In this work, two promising wind farm controls, based on wake redirection (WR) and dynamic induction control (DIC) strategy, are evaluated at the level of a single front-row wind turbine. To do so, a two-pronged analysis is performed. Firstly, the control techniques are evaluated in terms of the related impact on some specific key performance indicators, with special emphasis on ultimate loads and maximum blade deflection. Secondarily, an optimal blade redesign process is performed with the goal of quantifying the modification in the structure of the blade entailed by a possible increase in ultimate values due to the presence of wind farm control. Such an analysis provides for an important piece of information for assessing the impact of the farm control on the cost-of-energy model.

Environmental issues in the coastal regions of the south-eastern Baltic Sea: A sensitive natural environment in the face of increasing anthropic pressures
Authors: Gadal Sébastien , Gloaguen Thomas
Published: January 2022

In recent years, Latvian, Lithuanian, and the Oblast of Kaliningrad coastal zones have been experiencing a particularly intense and rapid anthropisation of the coastline due to political, social, and economic changes at the end of the Soviet period. These pressures are exerting on a highly sensitive environment, which has remained relatively untouched by any major development due to the militarisation of the coasts. The human stakes increased considerably in the coastal zone of the south-eastern Baltic with tourism, industrial development, and urban expansion. The environmental impacts and issues of the post-soviet anthropisation are analysed in this article through a bibliographic compilation related to the evolution of the coastal management policies reconciling environmental protection and economic development.

Published: January 2022

This article presents results of the test conducted on the undrained shear strength of till clayey soils of Eastern Lithuania, which are characterized by rigid and very stiff consistency and low plasticity. According to the classification of soils presented in LST EN ISO 14688–2:2018 Geotechnical Investigation and Testing – Identification and Classification of Soil − Part 2: Principles for a Classification, the tested soils are classified as sandy low plasticity clays. The undrained shear strength was tested using the triaxial compression (unconsolidated undrained) method. The test results showed that peculiarities of the particle size distribution had a crucial impact on the undrained strength of these soils, i.e. on the correlation of clay and fine silt fractions with the rest of soil components.
ENGLISH LANGUAGE LEARNERS IN INTRODUCTORY STATISTICS: LESSONS LEARNED FROM AN EXPLORATORY CASE STUDY OF TWO PRE-SERVICE TEACHERS
Authors: LESSER LAWRENCE M. , WINSOR MATTHEW S.
Published: January 2022

Despite the rapidly growing population of English language learners in U.S. colleges and schools, very little research has focused on understanding the challenges of English language learners specifically in statistics education. At a university near the United States-México border, the authors conducted an exploratory qualitative case study of issues of language in learning statistics for pre-service teachers whose first (and stronger) language is Spanish. The two strongest findings that emerged from cross-case analysis of the interviews were the importance of the role of context (the setting in which information is communicated) and the confusion among registers (subsets of language). This paper overviews and synthesizes relevant literature and offers resources and recommendations for teaching and future research.

Authors: MAYÉN SILVIA , DÍAZ CARMEN , BATANERO CARMEN
Published: January 2022

The focus of this research is the concept of median, which has received scarce interest in previous research. We analyse the open responses given by 518 Mexican students from Educación Secundaria (Junior) and Bachillerato (Senior) Secondary Education to a problem involving the computation of median. Using some ideas from the onto-semiotic approach, we classify the responses, taking into account the central tendency measure used, and describe the students’ semiotic conflicts. We use the chi-square test to study possible dependence between responses and students’ group. We observe better results in computation in Educación Secundaria students but better competence to select the best representative value in Bachillerato students.

Authors: Rashid Dr Samina , Khurshid Maryam , Saeed Hina
Published: January 2022

Psychological distress is a well-known term that has serious effect on the individual’s psychological and physical health. Now-a-days, it has become a topic of great concern for the psychosocial and educational adjustment amongst university students. The present study investigated the relationship between psychological distress, psychosocial adjustment and educational adjustment among university students. It also explored the moderating impact of self-efficacy on these variables. Data were collected from 304 university students (male=151, female=153). Kessler k10 Scale, General Self-efficacy Scale, Brief Adjustment Scale, Academic Adjustment Scale and Social Adjustment Scale were used to measure the study variables. Results of the current study revealed the inverse relationship between psychological distress, psychosocial and educational adjustment. Findings of regression analysis revealed that self-efficacy moderated the relationship between psychological distress, psychosocial adjustment and educational adjustment. Moreover, female students experienced more psychological distress as compared to male students. Results were discussed and limitations, suggestions and implications were presented for future research.
