Abstract:

Some factors such as interaction of migration process, cultural identity have an impact in a way that may lead to cultural disinheritance. Even if migrants' culture would not be lost, it may be affected by the new society culture. Therefore, it is anticipated that migration of an ethnic group would impact the culture of that group. Nubians; an ethnic group originated in South Egypt, have experienced migration that took place in the sixties of the past century. Nubians were forced to leave their origin land and relocate to Kom Ombo; an Egyptian town to the north of Aswan. The effect of migration on national culture, social homogeneity or the interest of social contact influences the attitudes of natives towards migration. Hence, it is very important for societies to help migrants to adapt to the new culture and at the same time not to impede migrants' effort to maintain their own culture. This study aims to investigate the effect of internal migration on the culture of Egyptian Nubians in order to predict if Nubian can maintain their own culture after the migration. Research question: what is the cultural influence of Nubians' migration from Egyptian Nubia to their new destinations? The researchers' hypothesis: there is mutual influence between the two cultures of Nubians and non-Nubians in Egypt. Results supported researchers' hypothesis as they observed that the Nubians managed to reserve balance between the maintenance of their own culture and the adoption of some cultural features of the community of their new destination(s). Also, the study examined why Nubians adhere to their culture although they left their land forever. Questionnaire and interviews were used to collect data from 80 informants; 40 Nubians and 40 non-Nubians in Kom-Ombo and the two cities of Cairo and Alexandria. Results suggested that there is obvious mutual cultural impact between Nubians and non-Nubians. The findings of this study would trigger the researchers to conduct further research on minorities for the deeper understanding of the impact of/on the culture of minorities.

Abstract:

In our school-based world, we are commonly confronted by young people for whom the study of science is an unpalatable ‘other world’: they simply do not see themselves as science (sciencey) people. To be clear, we are not interested in all young people becoming career scientists – although some small modicum of that would be quite agreeable. We are, though, keen to form or transform (trans(form)) their appreciations of science and retain open minds on matters scientific to develop the feeling of being ‘sciencey’ with or without the aspiration of becoming scientists. Our discussion in this paper draws upon research undertaken in a co-education primary- and lower-secondary school in Scotland, and our arguments chart the trans(formations) of thirty under-representative and under-researched Scottish South-Asian Muslim students (aged 11-13) over a school term. We use science identity theory as the basis for our analysis: what it means to be ‘sciencey’ and whether (or not) structural forces have impacted their decision of being ‘sciencey’. This work offers new insights into how Scottish, South-Asian, and Muslim students perceive and engage with in and out of school science and highlight some science nudges aimed to support their development of being ‘sciencey’.

Abstract:

Most of the world ecosystems have been affected by the effects of climate change. Efforts have been made to mitigate against climate change effects. While most studies have been done in forest ecosystems and pure plant plantations, trees on farms including agroforestry have only received attention recently. Agroforestry systems and tree cover on agricultural lands make an important contribution to climate change mitigation but are not systematically accounted for in the global carbon budgets. This study sought to: (i) determine tree diversity in different agroforestry practices; (ii) determine tree biomass in different agroforestry practices. Study area was determined according to the Land degradation surveillance framework (LSDF). Two study sites were established. At each of the site, a 5km x 10km block was established on a map using Google maps and satellite images. Way points were then uploaded in a GPS helped locate the blocks on the ground. In each of the blocks, Nine (8) sentinel clusters measuring 1km x 1km were randomized. Randomization was done in a common spreadsheet program and later be downloaded to a Global Positioning System (GPS) so that during surveys the researchers were able to navigate to the sampling points. In each of the sentinel cluster, two farm boundaries were randomly identified for convenience and to avoid bias. This led to 16 farms in Kakamega South and 16 farms in Kakamega North totalling to 32 farms in Kakamega Site. Species diversity was determined using Shannon wiener index. Tree biomass was determined using allometric equation. Two agroforestry practices were found; homegarden and hedgerow. Species diversity ranged from 0.25-2.7 with a mean of 1.8 ± 0.10. Species diversity in homegarden ranged from 1-2.7 with a mean of 1.98± 0.14. Hedgerow species diversity ranged from 0.25-2.52 with a mean of 1.74± 0.11. Total Aboveground Biomass (AGB) determined was 13.96±0.37 Mgha-1. Homegarden with the highest abundance of trees had higher above ground biomass (AGB) compared to hedgerow agroforestry. This study is timely as carbon budgets in the agroforestry can be incorporated in the global carbon budgets and improve the accuracy of national reporting of greenhouse gases.

Abstract:

Taste change is a common complication after Bariatric surgery (BS). However, the cause of this is still not clear. Since zinc is important fortaste perception, zinc deficiency, which is common after BS, may play an important role for taste change after BS. In this review, we aimto collate evidence relating to taste change and zinc deficiencyin relation to BS; effects of zinc replacement on taste perception in general and thereafter discuss the possible role of zinc deficiency to induce taste change after BS. A literature search was conducted, using four electronic bibliographical databases—EMBASE, PubMed, AMED and MEDLINE. We identified all available and relevant articles published before 30th February 2021.In total, 33 studies were included. The total number of participants analysed was N= 3264. We showed that taste change is a frequent complication after BS, especially after Roux-en-Y gastric bypass RYGBP comparing to other types of procedures. Patients' taste sensitivity differs among studies, but the most important decline in taste preference was observed for sweet food. Twelve studies investigating zinc deficiency following BS showed a significant decrease in zinc levels at six months after surgery. Supplementation with 45–50 mg of zinc sulphate was effective in improving taste, except in cancer patients, who showed no improvement in taste following zinc supplementation. Zinc deficiency appears to be associated with taste change after BS. Supplementation with much higher levels of zinc, at 45–50 mg, was effective in taste change treatment for many cases of taste disorder. The currently recommended levels of zinc replacements currently prescribed to patients following BS were not effective for avoiding zinc deficiency after BS—and thus not effective for averting taste change. It is therefore suggested that taste change following BS is closely related to zinc deficiency induced by the surgery.

Abstract:

Regions of South-East Europe are characterised by high out-migration for decades. The reasons for leaving range from the hope of a better work situation to a better health care system and beyond. In Serbia, this high out-migration hits the rural areas in particular so that the population number is in the red repeatedly. It might not be hard to guess that this negative population growth has the potential to create different challenges for those who stay in rural areas. So how are they coping with the – statistically proven – high out-migration? Having this in mind, the study is investigating the people‘s individual awareness of the social phenomenon high out-migration and their daily life strategies in rural areas. Furthermore, the study seeks to find out the people’s resilient skills in that context. Is the condition of high out-migration conducive for resilience? The methodology combines a quantitative and a qualitative approach (mixed methods). For the quantitative part, a standardised questionnaire has been developed, including a multiple choice section and a choice experiment. The questionnaire was handed out to people living in rural areas of Serbia only (n = 100). The sheet included questions about people’s awareness of high out-migration, their own daily life strategies or challenges and their social network situation (data about the social network was necessary here since it is supposed to be an influencing variable for resilience). Furthermore, test persons were asked to make different choices of coping with high out-migration in a self-designed choice experiment. Additionally, the study included qualitative interviews asking citizens from rural areas of Serbia. The topics asked during the interview focused on their awareness of high out-migration, their daily life strategies, and challenges as well as their social network situation. Results have shown the following major findings. The awareness of high out-migration is not the same with all test persons. Some declare it as something positive for their own life, others as negative or not effecting at all. The way of coping generally depended – maybe not surprising – on the people’s social network. However – and this might be the most important finding - not everybody with a certain number of contacts had better coping strategies and was, therefore, more resilient. Here the results show that especially people with high affiliation and proximity inside their network were able to cope better and shew higher resilience skills. The study took one step forward in terms of knowledge about societal resilience as well as coping strategies of societies in rural areas. It has shown part of the other side of nowadays migration‘s coin and gives a hint for a more sustainable rural development and community empowerment.

Abstract:

The built environment is responsible for about 40% of the world’s energy consumption and generates one third of global carbon dioxide emissions. The Green Building Council of South Africa’s (GBCSA) current rating tools are all for new buildings. By far the largest portion of buildings exist stock and therefore the need to develop a certification tool for existing buildings. Direct energy measurement comprises 27% of the total available points in this tool. The aim of this paper is to describe the development process of a green star certification tool for existing buildings in South Africa with specific emphasis on the energy measurement criteria. Successful implementation of this tool within the property market will ensure a reduced carbon footprint of buildings.

Abstract:

The present study answers the questions; how does climate change affect the water security in drought prone Ramanathapuram district? and what has water insecurity done to the health of the coastal community? The study area chosen is Devipattinam in Ramanathapuram district. Climate change evidentially wreaked havoc on the community with saltwater intrusion, water quality degradation, water scarcity and its eventual economic, social like power inequality within family and community and health hazards. The climatological data such as rainfall, minimum temperature and maximum temperature were statistically analyzed for trend using Mann-Kendall test. The test was conducted for 14 years (1989-2002) of rainfall data, maximum and minimum temperature and the data were statistically analyzed. At the outset, the water quality samples were collected from Devipattinam to test its physical and chemical parameters and their spatial variation. The results were derived as shown in ARC GIS. Using the water quality test water quality index were framed. And finally, key Informant interview, questionnaire were conducted to capture the gender perception and problem. The data collected were thereafter interpreted using SPSS software for recommendations and suggestions to overcome water scarcity and health problems.

Abstract:

As an offshoot of journalistic discourse, the documentary should be objective in nature without harbouring any preconceived notion to foster ulterior motifs. When it comes to a social issue like rape in South Asian countries, as media in recent times is inundated with this violent act in India, Pakistan, Myanmar, Bangladesh, how does one document it in terms of objectivity and subjectivity? The objective of this study is twofold: to document the history of documentaries, and to critically analyze South Asian rape/flesh trade-documentaries. The overall goal is to trace the (re/de)construction of objectivity-subjectivity in documentaries. This paper adopts a qualitative approach to documentarist discourse through the lens of critical discourse analysis (CDA). Data was gathered for 10 documentaries on the theme of rape and/or flesh trade from eight South Asian countries, predominantly the South Asian Association of Regional Cooperation (SAARC) region. The documentaries were primarily categorised by using three frameworks based on six modes, six subgenres, and four basic approaches of documentary. Subsequently, the findings were critiqued from CDA perspective. The outcome suggests that there a two schools of thoughts regarding documentaries. According to journalistic ethics, news and/or documentaries should be objective in orientation and focus on informing the audience and/common people. The empirical findings tend to challenge ethical parameters of objectivity. At times, it seems that journalistic discourse is discursively (re)constructed to give an augmented simulation of objectivity. Based on the findings it may be recommended that if documentaries steer away from empirical facts and indulge in poetic naivety, their credibility could be questioned. A research of this nature is significant as it raises questions with regard to ethical and moral conscience of documentary filmmakers. Furthermore, it looks at whether they uphold journalistic integrity or succumb to their bias, and thereby depict subjective views, which could be tainted with political and/or propagandist ulterior motifs.

Abstract:

Background: The unhealthy food choices and sedentary lifestyle of commercial drivers predisposes them to obesity and obesity related diseases. Yet, no attention has been paid to obesity burden among this high risk group in South Africa. This study examines the prevalence of obesity and its risk factors among commercial drivers in East London, South Africa. Methods: This cross-sectional study utilized the WHO STEP wise approach to screen for obesity among 403 drivers in Buffalo City Metropolitan Municipality (BCMM), South Africa. Anthropometric, blood pressure and blood glucose measurements were taken following a standard procedure. Overweight and obesity was defined as a body mass index (BMI) of 25.0 kgm⁻²–29.9 kg/m² and≥ 30 kg/ m², respectively. Bivariate and multivariate analysis were used to determine the prevalence and determinants of obesity. Result: The mean age of the participants was 43.3 (SD12.5) years, mean height (cm) and weight (kg) were 170.1(6.2cm) and 83(SD18.7), respectively. The prevalence of overweight and obesity was 34.0% and 38.0%, respectively. After adjusting for confounding factors, only age (OR 1.6, CI 1.0-2.7), hypertension (OR 3.6, CI 2.3-5.7) and non-smoking (OR 2.0, CI 1.3-3.1) were independent predictors of obesity. Conclusion: The prevalence of overweight and obesity is high among commercial drivers. Age, hypertension, and non-smoking were independent predictors of obesity among the sample. Measures aimed at promoting health and reducing obesity should be prioritized among this group.

Abstract:

Groundwater is the largest freshwater reservoir in the world. Like the other reservoirs of the hydrologic cycle, it is a finite resource. This study focused on the groundwater modeling of the Ter Kamerenbos well field to understand the groundwater flow system and the impact of different scenarios. The study area covers 68.9Km2 in the Brussels Capital Region and is situated in two river catchments, i.e., Zenne River and Woluwe Stream. The aquifer system has three layers, but in the modeling, they are considered as one layer due to their hydrogeological properties. The catchment aquifer system is replenished by direct recharge from rainfall. The groundwater recharge of the catchment is determined using the spatially distributed water balance model called WetSpass, and it varies annually from zero to 340mm. This groundwater recharge is used as the top boundary condition for the groundwater modeling of the study area. During the groundwater modeling using Processing MODFLOW, constant head boundary conditions are used in the north and south boundaries of the study area. For the east and west boundaries of the study area, head-dependent flow boundary conditions are used. The groundwater model is calibrated manually and automatically using observed hydraulic heads in 12 observation wells. The model performance evaluation showed that the root means the square error is 1.89m and that the NSE is 0.98. The head contour map of the simulated hydraulic heads indicates the flow direction in the catchment, mainly from the Woluwe to Zenne catchment. The simulated head in the study area varies from 13m to 78m. The higher hydraulic heads are found in the southwest of the study area, which has the forest as a land-use type. This calibrated model was run for the climate change scenario and well operation scenario. Climate change may cause the groundwater recharge to increase by 43% and decrease by 30% in 2100 from current conditions for the high and low climate change scenario, respectively. The groundwater head varies for a high climate change scenario from 13m to 82m, whereas for a low climate change scenario, it varies from 13m to 76m. If doubling of the pumping discharge assumed, the groundwater head varies from 13m to 76.5m. However, if the shutdown of the pumps is assumed, the head varies in the range of 13m to 79m. It is concluded that the groundwater model is done in a satisfactory way with some limitations, and the model output can be used to understand the aquifer system under steady-state conditions. Finally, some recommendations are made for the future use and improvement of the model.

Abstract:

Due to varying geographical and tectonic factors, the region of Saudi Arabia has been subjected to numerous natural and man-made maritime disasters during the last two decades. Natural maritime disasters, such as cyclones and tsunamis, have been recorded in coastal areas of the Indian Ocean (including the Arabian Sea and the Gulf of Aden). Therefore, the Indian Ocean is widely recognised as the potential source of future destructive natural disasters that could affect Saudi Arabia’s coastline. Meanwhile, man-made maritime disasters, such as those arising from piracy and oil pollution, are located in the Red Sea and the Arabian Gulf, which are key locations for oil export and transportation between Asia and Europe. This paper provides a brief overview of maritime disasters surrounding Saudi Arabia’s coastline in order to classify them by frequency of occurrence and location, and discuss their future impact the region. Results show that the Arabian Gulf will be more vulnerable to natural maritime disasters because of its location, whereas the Red Sea is more vulnerable to man-made maritime disasters, as it is the key location for transportation between Asia and Europe. The results also show that with the aid of proper classification, effective disaster management can reduce the consequences of maritime disasters.

Abstract:

The period of economic boom generated by the housing bubble created a climate of social indifference to the problem of corruption. This resulted in the persecution and conviction for these criminal offenses being low. After the economic recession, social awareness about the problem of corruption has increased. This has led to the Spanish citizenship requiring the public authorities to try to end the problem in the most effective way possible. In order to respond to the continuous social demands that require an exemplary punishment, the legislator has made changes in crimes against the public administration in the Spanish Criminal Code. However, from the point of view of criminal law, the social change has not served to modify only the law, but also the jurisprudence. After the recession, judges are punishing more severely these conducts than in the past. Before the crisis, it was usual for criminal judges to divert relevant behavior to other areas of the legal system such as administrative law and acquit in the criminal field. Criminal judges have considered that administrative law already has mechanisms that can effectively deal with this type of behavior in order to respect the principle of subsidiarity or ultima ratio. It has also been usual for criminal judges to acquit civil servants due to the absence of requirements unrelated to the applicable offense. For example, they have required an economic damage to the public administration when the offense in the criminal code does not require it. Nevertheless, for some years, these arguments have either partially disappeared or considerably transformed. Since 2010, a jurisprudential stream has been consolidated that aims to provide a more severe response to corruption than it had received until now. This change of opinion, together with greater prosecution of these behaviors by judges and prosecutors, has led to a significant increase in the number of individuals convicted of corruption crimes. This paper has two objectives. The first one is to show that even though judges apply the law impartially, they are flexible to social changes. The second one is to identify the erroneous arguments the courts have used up until now. To carry out the present paper, it has been done a detailed analysis of the judgments of the supreme court before and after the year 2010. Therefore, the jurisprudential analysis is complemented with the statistical data on corruption available.

Abstract:

The study examined the level of climate change awareness and perception by rice farmers in Jigawa State, Nigeria. A multi-stage and purposive sampling technique was used to select respondents. The state is divided into four agricultural zones namely Birninkudu zone, Gumel zone, Hadejia zone, and Kazaure zone. Two agricultural zones (Gumel zone and Hadejia zones) were purposively selected. Six Local Government Areas (LGAs) were randomly selected from the two zones. Also, twenty rice farmers were purposively selected from each of the LGAS. Data were analyzed using frequency and percentages. The result shows that 83.3% of the respondents are aware of the climate change impact on their rice output. Personal experience is the main sources of climate change information in the study area, another 45.6% adopted use of irrigation as the most effective measure to combating climate change, 25.5% use of early maturing variety. Further studies are needed on how to combat the threat and menace of the climate change in the study area.

Abstract:

Corruption is a ‘monster’ that can consume a whole nation, continent and even the world if it is not destroyed while it is still immature; It grows in the mind of the people, takes over their thinking and guides their decision-making process. Corruption snowballs into socio-economic catastrophe that might be difficult to deal with. Corruption which is a disease of the mind can be alleviated in Africa and the world at large by transforming a Corruption-Prone Mind to a Corruption-Immune Mind and to achieve this, we have to change our value system because the use of anti-graft agencies alone is not enough. Therefore, we have to fight corruption from the inside and the outside. Value System is the principle of right and wrong that are accepted by an individual or a social group; the reviewing and reordering of our value system is the solution to the problem of corruption as proposed by this research because the African society has become a ‘Money and Power Driven Society’ where the ‘I am worth concept’ which is a problematic concept has created an ‘Aggressive Society’ with grasping and money-grabbing individuals. We place more priority on money and the display of opulence. Hence, this has led to a ‘Triangular Society’ where minority is lavishing in plenty and majority is gasping for little. The get rich quick syndrome, the ethnicity syndrome, weakened educational system are signs of the prevalence of corruption in Africa This research has analyzed role and impact of the change in our value system in the fight against corruption in Africa and has therefore proposed the change in our value system as the way forward in the fight against corruption in Africa.

Abstract:

Climate change is regarded as one of the most fundamental threats to sustainable livelihood and global development. There is a growing global concern in linking community-managed forests as potential climate change mitigation projects. This study was conducted to explore local people’s perception on climate change and the role of community forestry (CF) to combat climate change impacts. Two active community forest user groups (CFUGs) from Kaski and Syangja Districts in Nepal were selected as study sites, and various participatory tools were applied to collect primary data. Although most of the respondents were unaware about the words “Climate Change” in study sites, they were quite familiar with the irregularities in rainfall season and other weather extremities. 60% of the respondents had the idea that, due to increase in precipitation, there is a frequent occurrence of erosion, floods, and landslide. Around 85% of the people agreed that community forests help in stabilizing soil, reducing the natural hazards like erosion, landslide. Biogas as an alternative source of cooking energy, and changes in crops and their varieties are the common adaptation measures that local people start practicing in both CFUGs in Nepal.

Abstract:

In this paper, the vulnerability level to climate change is analysed using a comprehensive index, consisting of five pillars: human, social, natural, physical, and financial. A structural equation model is also applied to determine the indicators and relationships that exist between the observed environmental changes and the quality of life. Using survey data to model the results, a value of 0.382 is derived as the vulnerability level for San Pedro, where values closer to zero indicates lower vulnerability and values closer to one indicates higher vulnerability. The results showed the social pillar to be most vulnerable, with the indicator ‘participation’ ranked the highest in its cohort. Although, the environmental pillar is ranked as least vulnerable, the indicators ‘hazard’ and ‘biodiversity’ obtained scores closer to 0.4, suggesting that changes in the environment are occurring from natural and anthropogenic activities. These changes can negatively influence the quality of life as illustrated in the structural equation modelling. The study concludes by reporting on the need for collective action and participation by households in lowering vulnerability to ensure sustainable development and livelihood.

Abstract:

Cycads are the most threatened plant species in the world. In South Africa over 70% of cycads are threatened with extinction with 60% of them as a result of bark harvest of these highly endangered species for medicinal purposes. 3 cycads species in South Africa have gone extinct due to bark harvest for medicinal purpose. This practice keeps increasing biodiversity loss within the nation and this has generated concern for conservationists on different way to discover how people go about this practices and how it can be discouraged. Studies have revealed this practice to be common practice in provinces like Kwazulu natal, Eastern cape, Gauteng, Mpumalanga, but studies in the past have not really focused on cycads bark harvest in Limpopo province. In this study we use the indigenous knowledge to discover a particular location within the Soutpansberg Montane (a major biodiversity hotspot in Limpopo Province in South Africa) in Vhembe district in Limpopo province not yet conserved where we have a highly disturbed population of cycads. Several individuals of cycads species have been highly damaged due to bark harvest in this location. We are about proposing that such areas needs attention for conservation to prevent the loss of these species endemic to this particular location. Our study hereby reveals that cycads bark harvest which is a major threat to African cycads is also a common practice in Limpopo Province in South Africa. Rigorous conservation action is required to discourage this practice in order to prevent further biodiversity loss in this region.

Abstract:

The Indian subcontinent is facing a massive challenge with regards to energy security in member countries, to provide reliable electricity to facilitate development across various sectors of the economy and consequently achieve the developmental targets. The instability of the current precarious situation is observable in the frequent system failures and blackouts. The deployment of interconnected electricity ‘Supergrid’ designed to carry huge quanta of power across the Indian sub-continent is proposed in this paper. Besides enabling energy security in the subcontinent, it will also provide a platform for Renewable Energy Sources (RES) integration. This paper assesses the need and conditions for a Supergrid deployment and consequently proposes a meshed topology based on Voltage Source High Voltage Direct Current (VSC-HVDC) converters for the Supergrid modeling. Various control schemes for the control of voltage and power are utilized for the regulation of the network parameters. A 3 terminal Multi Terminal Direct Current (MTDC) network is used for the simulations.

Abstract:

Due to the contractual nature of jobs and employment opportunities in the construction industry and the seeming surplus of potential employees in South Africa, there is a little interest on the part of employers to put in place policies to retain experienced workers. Ironically these are the workers that the companies have expended significant resources on, in terms of training and capabilities development. The construction industry has been experiencing high materials wastages and health and safety issues to score very low on the sustainability agenda as regards resources management and safety. This study carried out an assessment of the poor retention of experienced workers in the construction industry on the capacity to deliver sustainable housing in South Africa. It highlights the economic, safety and resources conservation and other benefits accruable from a high retention of key employees to the South African construction industry towards the delivery of sustainable housing. It presents data that strongly support the hypothesis that high turnover of skilled employees as a result of the industry belief of zero incentive to retain employees beyond the contractual period, is responsible for the high wastages of resources in the industry and the safety issues. A high turnover of experienced employees in the construction industry was found to impact on the industry performance in terms of timely, cost effective and quality delivery of construction projects, particularly when measured against the government sustainable housing agenda. It also results in unplanned expenses required to train replacing employees during project executions as well as company goodwill which ultimately has a huge impact on sustainable housing delivery in South Africa.

Abstract:

Backgrounds: Depression is a prevalent mental health concern among university students. This cross-sectional study explores the factors associated with depression among university students in Vietnam. Methods: In 2022, a web-based survey was conducted among 2,304 students from different universities across North, Central, and South Vietnam. The Pearson chi-squared test was used to analyze the statistical associations between socio-demographic factors, depression levels, and social media addiction. Results: The results showed that 33,9% of freshmen experienced severe depression, with higher rates among females (69,8%) than males (30,2%). Health field students had the highest proportion of severe depression (52%). Social media addiction was prevalent among freshmen (29%) and health students (54,4%). Factors such as family infections, study pressure, hometown, studying in public places, and social media addiction were strongly linked to higher depression levels. However, spending more time communicating with friends and studying at home had a protective effect against depression. Notably, social media addiction was significantly associated with increased depression levels. Conclusion: The study highlights the influence of family COVID-19 infections, academic pressures, studying in public places, hometown, social media addiction, and lack of social interactions on depression levels.

Abstract:

Assam from an early period has gone through various religious transformations and has witnessed its impact in different period. One of such epoch is the epoch of Srimanta Shankardeva. Srimanta Shankareva is regarded, as the greatest religious preacher and social reformer in the history of Assam. It was Shankardeva, who brought the faith of vaisnavite movement that prevailed in other parts of India. Before and during his time, the people of Assam were followers of Sakta worship, the worshipping of different gods and goddesses. People worshiped idols and offered sacrifices. Srimanta Shankardeva under the faith neo-vaishnavism and propagated the Eka-Saran-Naam-Dharm, through which spread the splendor of one and only Lord Vishnu or Krishna and abolished offering sacrifices. With the help of Eka-Saran-Naam-Dharma, Srimanta Shankardeva tries to vanish the superstitious beliefs and irrational practices of Assamese society. The NeoVaishnavite faith developed a democratic outlook which permeates the entire teachings and practices in Assamese people. His contributions not only made the foundations of Assamese literature, culture, and social structure but also established the super structures the upon. It is understood that all contributions of Srimanta Shankardeva bear his marks distinctively. Religion is said to be biggest and the most influential aspect in bringing about change in the society. In Assam, with the essence of neo-vaishnavism by Shankardeva and the emergence of the Eka-Saran-Naam-Dharma came into a huge Change to the region. The movement of religion brought about a social mobility to all sections of society. This paper is a mere initiative to look into the organizational structure of Srimanta Shankardeva Sangha and its maintenance of the ideology and principles without failure. It is aimed to examine the assimilation of different groups and communities of people under the fold of Srimanta Shankardeva Sangha.

Abstract:

All beach areas in South Africa are constituted as public land, open to all to walk on or swim in these spaces. With the completed development of the Durban promenade in 2023 from the Umgeni estuary to the harbour entrance, Durban’s beachfront promenade is a notable example of innovative urban design that has transformed formerly segregated spaces into a paved public walkway linking over 15 beaches. Public spaces, however, are not all created equally, with ideas on how individuals and groups become the producers of space can be a useful tool for designing future public spaces. It is the role of planners, architects, and other built environment specialists to ensure inclusivity and symbiosis between how spaces are separated and then created. Lefebvre’s ideas about space and social practice provide a foundation for this research, specifically on how spaces like the Durban promenade function as democratic spaces, highlighting questions of what draws individuals and groups to certain areas on the promenade are important. Some public spaces are well designed, accessible, and inclusive, while others create more contestation amongst users. In this research article, Durban’s beachfront promenade is used as a case study to better understand the creation of public spaces, more specifically regarding who uses the beachfront promenade and for what reasons. This research adopts a phenomenological and descriptive approach to understanding place by exploring human experiences, emotions and meanings individuals attach to the beachfront promenade and how social processes and interactions shape our understanding, experience, and meaning of places. This research will collect both qualitative and quantitative data along specific nodes located on the beachfront promenade to determine the number of visitors based on demographics such as age, race and gender and the perceptions of visitors to these nodes. The aim is to coordinate and give meaning through surveys and visitor observations to better understand the type of perceptions people have of these spaces, for example, the rationale for utilising space, which already encompasses several activities ranging from cultural, social, economic, environmental, spiritual, physical as well as numerous others.

Abstract:

The use of social networking sites had been a big part of life of most people. One of the most popular among these is Facebook. Users range from young adults to late adults. While it is more popular among emerging and young adults, this social networking site gives people opportunities to express the self. Via Facebook, people have the opportunity to think about what they prefer to show others. This study identified which among the multiple facets of the self (real self, false self or ideal self) is dominantly presented by young adults and middle adults in using the social networking site Facebook. South Metro Manila was the locale of this study where 100 young adult participants (aged 18-25) were students from nearby universities and the 100 middle adult participants (aged 35-45) were working residents within the area. Participants were comprised of 53% females and 47% males. The data was gathered using a self-report questionnaire to determine which online self-presentation (real self-presentation, false self-presentation, or ideal self-presentation) of the participants has greater extent when engaging in the social networking site Facebook. Using means comparison, results showed that both young adults and middle adults engaged primarily in real self-presentation.

Abstract:

In this study, we discuss the properties of absolute void space or the universe at zero seconds, and how these properties play a vital role in creating a mechanism in which the very first particle gets created simultaneously everywhere. We find the limit in which when the absolute void volume reaches will lead to the collapse that leads to the creation of the first particle. This discussion is made following the elementary dimensions theory study that was peer-reviewed at the end of 2020; everything in the universe is made from four elementary dimensions, these dimensions are the three spatial dimensions (X, Y, and Z) and the Void resistance as the factor of change among the four. Time itself was not considered as the fourth dimension. Rather time corresponds to a factor of change, and during the research, it was found out that the Void resistance is the factor of change in the absolute Void space, where time is a hypothetical concept that represents changes during certain events compared to a constant change rate event. Therefore, time does exist, but as a factor of change as the Void resistance: Time= factor of change= Void resistance.

Abstract:

Climate change effects on the hydrologic cycle are the main concern for the evaluation of water management strategies. Climate models project scenarios of precipitation changes in the future, considering greenhouse emissions. In this study, the EURO-CORDEX (European Coordinated Regional Downscaling Experiment) climate models were first evaluated in a Mediterranean island (Sardinia) against observed precipitation for a historical reference period (1976-2005). A weighted multi-model ensemble (ENS) was built, weighting the single models based on their ability to reproduce observed rainfall. Future projections (2071-2100) were carried out using the 8.5 RCP emissions scenario to evaluate changes in precipitations. ENS was then used as climate forcing for the SWAT model (Soil and Water Assessment Tool), with the aim to assess the consequences of such projected changes on streamflow and runoff of two small catchments located in the South-West Sardinia. Results showed that a decrease of mean rainfall values, up to -25 % at yearly scale, is expected for the future, along with an increase of extreme precipitation events. Particularly in the eastern and southern areas, extreme events are projected to increase by 30%. Such changes reflect on the hydrologic cycle with a decrease of mean streamflow and runoff, except in spring, when runoff is projected to increase by 20-30%. These results stress that the Mediterranean is a hotspot for climate change, and the use of model tools can provide very useful information to adopt water and land management strategies to deal with such changes.

Abstract:

Traditionally, non-compliance in water regulation has been understood to be attributable to lack of information or knowledge of regulations. In other words, it is confusing behavioural change and education with communication or regulations. However, compliance is a complex response to water regulation factors including 1) knowledge and understanding of regulations; 2) perception that resources are overregulated; 3) presence of regulatory officers in the field; 4) accurate communication of what is being protected; 5) time lag between behavioral change projects and observation of outcomes and 6) how success of behavioral change is measured and evaluated. This paper presents a framework for designing education and behavioral change projects by understanding non-compliance in terms of the interaction of its factors, including a process for prioritizing projects, actions, evaluation and monitoring of outcomes. By taking a systemic approach to compliance, a more directed type of actions can be efficiently identified and prioritized, preventing the reactive nature of education and behavioral change projects.

Abstract:

The Mitar program was established to drive a shift in middle school mathematics education, emphasizing the connection of math to real-life situations, exploring mathematical modeling and literacy, and integrating social and emotional learning (SEL) components for enhanced excellence. The program envisions math coordinators as catalysts for change, equipping them to create educational materials, strengthen leadership skills, and develop SEL competencies within coordinator communities. These skills are then employed to lead transformative efforts within their respective schools. The program engaged 90 participants across six math coordinator communities during 2022-2023, involving 30-60 hours of annual learning. The process includes formative and summative evaluations through questionnaires and interviews, revealing participants' high contentment and successful integration of acquired skills into their schools. Reflections from participants highlighted the need for enhanced change leadership processes, often seeking more personalized mentoring to navigate challenges effectively.

Abstract:

Home garden has proved to be significant to rural inhabitants by providing a wide range of useful products such as fruits, vegetables and medicine. There is need for quantitative information on its benefits and contributions to rural household. The main objective of this study is to investigate contributions of home garden to income of rural households in Raymond Mhlaba Local Municipality, formerly Nkonkobe Local Municipality of Eastern Cape Province South Africa. The stratified random sampling method was applied in order to choose a sample of 160 households.The study was conducted among 80 households engaging in home gardens and 80 non- participating households in the study area. Data analysis employed descriptive statistics with the use of frequency table and one way sample T test to show actual contributions. The overall model shows that social grant has the highest contribution to total household income for both categories while income generated from home garden has the second largest share to total household income, this shows that the majority of rural households in the study area rely on social grant as their source of income. However, since most households are net food buyers, it is essential to have policies that are formulated with an understanding that household food security is not only a function of the food that farming households produce for their own consumption but more so a function of total household income. The results produced sufficient evidence that home gardens contribute significantly to income of rural household.
