Abstract:

The impacts of divorce are not only felt by parents but also by children. Preschool children are the most distressed while facing parental divorce. The negative impacts of divorce on children can be minimized when children had pervious knowledge about the event. One of the method to give knowledge about divorce to children is through picture book. Unfortunately, in Indonesia, researchers have not found picture books for preschoolers about divorce. This study aims to test the effectiveness of picture book in increasing knowledge of preschool children about divorce. Formulation of picture books in this study is based on three sources of information: (1) the study of literature, (2) analysis of picture books, and (3) need assessment. This picture book that have been prepared, then used to test its effectiveness for increasing knowledge of preschool children about divorce. The test was conducted using pre and post test on 5 participants. The statistical method used in this study is paired sample t-test. The purposive sampling method was used to select the participants. The participants for this study are preschool children with parents that is undergoing divorce proceedings. The result shows that picture books in this study significantly increase preschool children's knowledge about divorce. As an additional result, parents find it easier to explain divorce to their children using the picture book from this study. For further study, researcher can make another picture book about divorce for children at different age or to face another challenging situation in life.

Abstract:

Communication of sexual matters between the parents and adolescents has been seen as one of the strategies that could play a cardinal role in encouraging adolescents to be responsible and delay sexual debut or avoid unprotected sexual intercourse. The increasing rate of teenage pregnancies and new HIV/AIDS infections among adolescents in Sub-Saharan Africa makes the phenomenon worth analysis. The purpose of this paper is to interrogate the dynamics of parent-adolescent communication on sexual and reproductive health in Sub-Sahara. Specifically the paper focuses on barriers to communication between parents and adolescents on sexual and reproductive health and its policy implications. It emanates from the paper that communication on sexual and reproductive health at household level is triggered by death of a relative from a sexual related illness, suspicion on sexual activity, radio programmes and in some instances fliers. Literature engagement reveals that communication between parents and adolescents on sexual and reproductive health is made difficult by economic factors (poverty, lack of privacy and low self-esteem), household demographics (age, sex, class, death), socio-cultural factors (beliefs and religious values) as well as social media. We argue that there is need to use broadcast mediato come up with radio and television programmes that create family environments in which sexual and reproductive health issues are discussed. We also recommend that government departments and Non-Governmental Organisations concerned with sexuality issues need to undertake studies that can help dismantle taboos, prejudices and stereotypes that impede sexual and reproductive health communication between parents and adolescents.

Abstract:

Within the professional research literature on parenting in the United States, there is a paucity of research on parenting within the African American or Black community. Research on parenting focused on African Americans within the upper middle class, who constitute a critical and growing sector within the African American population, is all but non-existent. Research to address this void is needed. Despite the progress that has been made toward eliminating the long-standing racial divides in U.S. society, these divides persist and continue to affect different experiences and opportunity structures for White Americans versus Black Americans, including those in the upper middle class. Achievement of middle and upper middle class status of adult heads of families has generally been seen as the route to greater success and well-being for their children. While higher family class status is positively correlated with these factors, the strength of the relationship between higher social class and success and well-being is weaker for Black American families as compared to White American families. In light of the realities of racial inequality, African American parents, including those who have achieved higher status, have unique concerns for their children. African American parents, on the basis of their own experiences and their sense of the world as being highly racialized, anticipate the kinds of experiences that their children are likely to encounter as they grow and mature from childhood to adulthood and beyond. Racial discrimination and macro and micro racial aggressions are continued sources of concern for these parents. On the basis of in-depth personal interviews with upper middle class African American parents, findings suggest that the parenting goals and strategies of African American parents are influenced by the continuing significance of race as a social divide, including in higher socio-economic strata, in the United States. Black American families' parenting practices differ from those of White American families and are inclusive of the unique factors that threaten the well-being of African American children. Specifically, parenting practices are shaped by parents' fears about the racial experiences that they anticipate that their children will encounter. Parents' perceptions of parental effectiveness are linked to their ability to prepare their children for success in confronting, understanding, and contextualizing racial inequalities and aggressions. Theories of Parental Projective Care are useful in understanding the special considerations and unique parenting goals and behaviors of higher status African Americans.

Abstract:

This study explores the effects of parents’ personality and family variables on aggressive behavior in children from the State of Kuwait. The sample of 117children aged between 6 and 10 years (M=7.79 years, SD =1.4 years),117 fathers, and 117mothers from Kuwait. The following tools were used: a) the Aggressive Behavior Scale for Children (ABSC), b) the Personality Scales Inventory (PSI), and c) the Family Climate Scale (FCS). The results show that there were significant differences between children with highly aggressive behavior and those with low aggressive behavior for most of the personality traits of the father and mother, as well as most of the family climate and its different dimensions according to the father’s knowledge and the mother’s knowledge. Furthermore, there was a significant difference between males and females in the total score of aggressive behavior, verbal aggression, physical aggression, self-aggression, and aggression toward others, with higher scores occurring among males. Most of the correlations of the children’s aggressive behavior were with the personality traits of the father. The personality traits of the mother, family climate, and most of its different dimensions according to the father's and mother's knowledge had significant negative correlations with the child's aggression. There was no effect of the mother's and father's education levels on their child’s aggressive behavior. There was a significant difference between normal families and separated families in the total score of aggressive behavior, verbal aggression, and self-aggression, with a higher score occurring among separated families, and there was no significant difference between the two groups in physical aggression and aggression towards others.

Abstract:

Quality of family relations is an important factor of child development, however, the role of joint family activities on adolescent happiness still needs investigation. The aim of this study is to analyze associations between happiness of school-aged children and parental involvement. The analysis involves Lithuanian data from the cross-sectional Health Behaviour in School Aged Children (HBSC) study. The sample comprised 5730 children aged 11–15 years. Results: The odds of happiness was 2.38 times higher if children were living together with mother (95% CI: 1.81–3.13) and 1.81 times – with father (95% CI: 1.53–2.15). However, the likelihood of happiness was 7.21 times lower if adolescent had difficulties to talk with mother (95% CI: 5.42–9.61) and 6.40 times – with father (95% CI: 4.80–8.56). The joint daily adolescents-parents activities also predict the odds for happiness: joint TV watching by 5.96 times (95% CI: 4.21–8.43), having meals together by 7.02 times (95% CI: 4.77–10.32), going for a walk together 4.30 times (95% CI: 2.96–6.26), visiting places by 6.85 times (95% CI: 4.74–9.90), visiting friends and relatives by 7.13 times (95% CI: 4.87–10.43), sporting by 2.76 (95% CI: 1.83–4.18) as well as discussing various things by 7.35 times (95% CI: 5.50–9.82). Conclusions: Joint parents-adolescents activities and communication are related with greater happiness of adolescent. Though adolescence is a period when the relationships with peers get more importance, the communication and joint activities with parents remain a significant factor of adolescent happiness.

Abstract:

Farmers try to reduce steps of soil preparation by using subsoiler and then following by equipment for soil pulverization such as a rotary tiller and a power harrow which take advantage of using a power take-off of a tractor. Therefore, this study was conducted to compare the tilling performances of a rotary tiller and a power harrow applying after subsoiling. The results showed that both the rotary tiller and the power harrow had negative slip, indicating that they generated force to push a tractor. The rotary tiller created negative vertical force to lift up the tractor whereas opposite result was found when using the power harrow. Since working depths were different, vertical forces, torques and PTO powers for two equipment types were significantly different. However, no significant differences were found for the forward speeds, slips, drawbar pulls and drawbar powers. Comparative analysis showed that two equipment types had significant difference in PTO power to working depth, drawbar power to working depth, PTO power to working area, drawbar power to working area and soil pulverization.

Abstract:

Hidden Markov Model (HMM) has been used in prediction and determination of states that generate different neural activations as well as mental working conditions. This paper addresses two applications of HMM; one to determine the optimal sequence of states for two neural states: Active (AC) and Inactive (IA) for the three emission (observations) which are for No Working (NW), Waiting (WT) and Working (W) conditions of human beings. Another is for the determination of optimal sequence of intentionality i.e. Believe (B), Desire (D), and Intention (I) as the states and three observational sequences: NW, WT and W. The computational results are encouraging and useful.

Abstract:

The aim of this work was to analyze the relation between children´s effortful control, marital adjustment and parenting practices in a sample of 345 Spanish children aged between 6 and 8 years. Traditionally, the literature confirms that a higher level of marital conflict has been associated with less effective and less positive parenting, but there are few studies that include the effect that children´s effortful control exert to this relation. To measure marital adjustment, parenting practices and children’s temperament, parents were given the Marital Adjustment Test (MAT), the Spanish version of the PCRI (Parent-Child Relationship Inventory), and the TMCQ (Temperament in Middle Childhood Questionnaire). The results confirmed that higher marital satisfaction predicted more positive parenting practices, whereas lower marital adjustment scores predicted less parenting support and control. Using a statistical modeling approach, we tested a moderation model that revealed the moderating role of effortful control in the relation between marital adjustment and parenting. Concretely, higher marital satisfaction predicts higher parenting communication and involvement, but only in children with low levels of effortful control. Therefore, a difficult temperament interferes in a less negative way in the family system when parents are satisfied and united. And a better self-regulated child predicts more effective parenting practice regardless of the parents´ marital satisfaction. The clinical implications of the present findings should be considered. Specifically, difficult children must be detected and evaluated in community settings, such as school or community programs, in order to take into account the marital adjustment and parenting practices of their parents, and to be able to design adequate family interventions and prevent future pathologizing patterns.

Abstract:

Following the recent political conflict in the Middle East, the number of refugees and internally displaced people increased in the last decades. The flood of displaced people became a big issue for the host communities in the neighbouring countries and Europe. The need for research about the education and integration of the refugees became urgent. After the appearance of the Islamic State and displacing millions of Syrian people, the Kurdistan Region of Iraq became a safe shelter for hundreds of thousands of Syrians and international organisations helping the refugees. This study focuses on the factors of parental involvement among the host community and refugee parents and its role in the academic success of children. The setting is the three provinces of Iraqi Kurdistan (Erbil, Sulaimani, and Dohuk), including the refugee camps in the three provinces. Based on the purpose of the study, the study was designed as a descriptive survey study with a mixed approach, qualitative (open-ended), and quantitative (questionnaire) questions and both forms of data were integrated and analysed. The current study participants were 8th and 9th graders at the basic school level, studying at public schools and their parents. The sampling design was the selection of local schools and schools in the refugee camps in the region's three provinces. The number of participants for each of the two groups was 250 students and 250 parents. The results showed that parents' socioeconomic status, gender, and place of residency have significant roles in students' parental involvement and academic success of their students. The results also show the characteristics of parental inspiration to their children's future and their expectations from education.

Abstract:

The purpose of this study was to investigate the effect of reaction time (RT) or balance performance as the number of stimulus-response choices increases, the amount of information processing of 0-bit and 1-bit conditions based on Hick’s law, using the dual-task design. Eighteen children (age: 9.38 ± 0.27 years old) were recruited as the participants for this study, and asked to assess RT and balance performance separately and simultaneously as following five conditions: simple RT (0-bit decision), choice RT (1-bit decision), single balance control, balance control with simple RT, and balance control with choice RT. Biodex 950-300 balance system and You-Shang response timer were used to record and analyze the postural stability and information processing speed (RT) respectively for the participants. Repeated measures one-way ANOVA with HSD post-hoc test and 2 (balance) × 2 (amount of information processing) repeated measures two-way ANOVA were used to test the parameters of balance performance and RT (α = .05). The results showed the overall stability index in the 1-bit decision was lower than in 0-bit decision, and the mean deflection in the 1-bit decision was lower than in single balance performance. Simple RTs were faster than choice RTs both in single task condition and dual task condition. It indicated that the chronometric approach of RT could use to infer the attention requirement of the secondary task. However, this study did not find that the balance performance is interfered for children by the increasing of the amount of information processing.

Abstract:

Primary schooling in Taiwan is in a process of radical restructuring during the decade. At the center of these restructuring is the position of the principal and questions to do with how principals, as school leaders, respond to radical change. Adopting a case-study approach, the study chose a middle Taiwanese primary school to investigate how the principal learned to be political. Using micropolitical leadership, the principal at the researched site successfully coped with internal change and external demands. On the whole, judging from the principal’s leadership style on the mediation between parents and teachers, as well as school-based curriculum development, it could be argued that the principal was on the stance of being a leader of the cultural transformation instead of cultural reproduction. In doing so, the qualitative evidence has indicated that the principal seemed to be successful in coping with the demands of rapid change. Continuing learning for leadership is the core of working as a principal.

Abstract:

The purpose of this research was to study the influence of accountants’ potential performance on their working process, a case study of Government Savings Banks in the northeast of Thailand. The independent variables included accounting knowledge, accounting skill, accounting value, accounting ethics, and accounting attitude, while the dependent variable included the success of the working process. A total of 155 accountants working for Government Savings Banks were selected by random sampling. A questionnaire was used as a tool for collecting data. Descriptive statistics in this research included percentage, mean, and multiple regression analyses. The findings revealed that the majority of accountants were female with an age between 35-40 years old. Most of the respondents had an undergraduate degree with ten years of experience. Moreover, the factors of accounting knowledge, accounting skill, accounting a value and accounting ethics and accounting attitude were rated at a high level. The findings from regression analysis of observation data revealed a causal relationship in that the observation data could explain at least 51 percent of the success in the accountants’ working process.

Abstract:

Introduction: Child maltreatment was proven to negatively impact children’s and adolescent’s academic performances; showing less academic achievements, problems completing homework assignments, and was marginally associated with being frequently absent from school (1). Objectives: To identify the impact of child maltreatment on school performance among adolescents in National Guard Schools. Materials and Methods: The study was conducted at National Guard schools in Riyadh. Students aged 12-19 years were invited to participate. Participants (N=674) completed the survey instrument which included demographics, exposure to different types of abuse, and overall level of academic performance. Results: Participants’ mean age was 15.6±1.6 years and males (53%). Ninety-five percent lived with both parents, 2% with single parent, and 3% with step parents. Four percent lived with alcoholic parents or guardians, and 7% have lived with a family member who has been arrested or imprisoned. Poor performance (failure in exam) were more likely among the students who lived with alcoholics vs. non-alcoholics (33% vs. 11%, p<0.01), imprisoned family member vs. non-imprisoned (26% vs. 11%, p<0.01), psychologically abused vs. not abused (21% vs. 10%, p<0.01), physically abused vs. not abused (19% vs. 9%, p<0.01). Predisposing factors to poor performance in school included living with alcoholic parents or guardians (OR=2.8, CI=1.1-6.7), psychologically abused (OR=1.7, CI=1.0-3.0), and physically abused (OR=1.7, CI=1.0-2.8). Conclusions: The results suggest that child maltreatment may adversely impact school performance. These findings highlight the importance of increasing the awareness about the impact of child maltreatment on school performance among families, schools, and the community. Recommend to the Ministry of Education to consider counseling of students with poor performance due to adverse child experiences or maltreatment.

Abstract:

Much has been written about the promotion of Standard Mandarin and the negative effects it may have had on the development of non-Mandarin dialects. Less discussed, however, is the fate of northern Chinese dialects that are only marginally different from Standard Mandarin and the effect Standard Mandarin promotion may have had on such dialects. In this paper, we seek to bridge this gap by looking at language preferences in the family and the generational differences that they reflect. Specifically, we survey Mandarin dialect speakers from Xinle county in Hebei province, whose local dialect is similar but not identical to Standard Mandarin. We sample more than 160 families with pre-middle school children and ask the parents a series of questions that probe language behavior, language ability, and language attitude within the family with regard to educating the young. Our study shows that although most parents still speak the Xinle dialect, Standard Mandarin has become the language taught to the majority of children. We also show that only one-third of parents choose to preserve elements of Xinle dialect in the language they teach to their children. We analyze the possible factors (e.g., subjective, geographical, social, and external) that influence language choice and show how these factors collectively contribute to the current state of family language choice for educational purposes. Finally, based on our findings, we offer recommendations for coordinating the promotion of Standard Mandarin and dialect preservation in similar Mandarin-speaking regions.

Abstract:

Mindfulness-based interventions (MBI) can be beneficial for the well-being of children. MBIs offered for children in contexts of vulnerability (poverty, neglect) report positive results in terms of emotion regulation and cognitive flexibility. Anxiety is a common issue for children living in a vulnerable context. It has a negative impact on children’s attention span, emotional regulation and self-esteem. The MBI (12 weeks) associated with this research has been developed for a total of 30 children suffering from anxiety (7 to 9 years old) and receiving services from a community center over the last seven years. The first objective is to describe in details the content of the mindfulness-based intervention. The second purpose is to document what helps and what hinders the practice of mindfulness for children living in a context of vulnerability. A special attention will be given to the importance of the way that the intervention is offered and the principles that are followed by the practitioners. Perceived effects of the intervention on children were collected through an individual semi-structured interview with each child at the end of the program. Parents were also interviewed to have their point of view on the effect of their children’s participation in the group. Anxiety was measure with the Beck youth pre-post and at follow up (2 months). Qualitative analysis of the interviews with children showed that most of them mentioned that the program helped them become calmer, more confident, less scared and more able to deal with difficult emotions. Almost all of them reported having used the material provided to them to practice at home. This result has been confirmed by parents. They reported that their child had gained confidence and were better at verbalizing emotions. Children also grew calmer, even though all anxiety was not gone. They would have liked more material to practice at home. The quantitative instrument used to measure anxiety did not corroborate the qualitative interviews about anxiety. Discussion will question the use of this questionnaire for children who have important cognitive limitations. Discussion will also report the importance of the personalized contact with children, along with other consideration, to enhance the adherence of children and parents. The MBI seems to have benefited children in different ways, which is corroborated by most parents. Since the sample was limited, we will need to continue documenting its effects with more children and parents. The major strength of this research is to have reported the subjective perspectives of children on their experience of mindfulness.

Abstract:

Purpose: To validate virtual non-contrast reconstructions generated from dual-layer spectral computed tomography (DL-CT) data as an alternative for the acquisition of a dedicated true non-contrast dataset during multiphase contrast studies. Material and methods: Thirty-three patients underwent a routine multiphase clinical CT examination, using Dual-Layer Spectral CT, from March to August 2021. True non-contrast (TNC) and virtual non-contrast (VNC) datasets, generated from both portal venous and arterial phase imaging were evaluated. For every patient in both true and virtual non-contrast datasets, a region-of-interest (ROI) was defined in aorta, liver, fluid (i.e. gallbladder, urinary bladder), kidney, muscle, fat and spongious bone, resulting in 693 ROIs. Differences in attenuation for VNC and TNV images were compared, both separately and combined. Consistency between VNC reconstructions obtained from the arterial and portal venous phase was evaluated. Results: Comparison of CT density (HU) on the VNC and TNC images showed a high correlation. The mean difference between TNC and VNC images (excluding bone results) was 5.5 ± 9.1 HU and > 90% of all comparisons showed a difference of less than 15 HU. For all tissues but spongious bone, the mean absolute difference between TNC and VNC images was below 10 HU. VNC images derived from the arterial and the portal venous phase showed a good correlation in most tissue types. The aortic attenuation was somewhat dependent however on which dataset was used for reconstruction. Bone evaluation with VNC datasets continues to be a problem, as spectral CT algorithms are currently poor in differentiating bone and iodine. Conclusion: Given the increasing availability of DL-CT and proven accuracy of virtual non-contrast processing, VNC is a promising tool for generating additional data during routine contrast-enhanced studies. This study shows the utility of virtual non-contrast scans as an alternative for true non-contrast studies during multiphase CT, with potential for dose reduction, without loss of diagnostic information.

Abstract:

Conducting crystallization in an agitated vessel requires a proper selection of mixing parameters that would result in a production of crystals of specific properties. In dual impeller systems, which are characterized by a more complex hydrodynamics due to the possible fluid flow interactions, revealing a clear link between mixing parameters and crystallization kinetics is still an open issue. The aim of this work is to establish this connection by investigating how fluid flow patterns, generated by two impellers mounted on the same shaft, reflect on metastable zone width of borax decahydrate, one of the most important parameters of the crystallization process. Investigation was carried out in a 15-dm³ bench scale batch cooling crystallizer with an aspect ratio (H/T) equal to 1.3. For this reason, two radial straight blade turbines (4-SBT) were used for agitation. Experiments were conducted at different impeller spacings at the state of complete suspension. During the process of an unseeded batch cooling crystallization, solution temperature and supersaturation were continuously monitored what enabled a determination of the metastable zone width. Hydrodynamic conditions in the vessel achieved at different impeller spacings investigated were analyzed in detail. This was done firstly by measuring the mixing time required to attain the desired level of homogeneity. Secondly, fluid flow patterns generated in a described dual impeller system were both photographed and simulated by VisiMix Turbulent software. Also, a comparison of these two visualization methods was performed. Experimentally obtained results showed that metastable zone width is definitely affected by the hydrodynamics in the crystallizer. This means that this crystallization parameter can be controlled not only by adjusting the saturation temperature or cooling rate, as is usually done, but also by choosing a suitable impeller spacing that will result in a formation of crystals of wanted size distribution.

Abstract:

Due to the fact that cyberbullying victimization is an increasing problem nowadays, affecting more and more children and adolescents around the world, we wanted to take a step forward analyzing this phenomenon. So, we took a look at some variables which haven't been studied together before, trying to develop another way to view cyberbullying victimization. We wanted to test the effects of the mother, father, and peer attachment on adolescent involvement in cyberbullying as victims through unconditional self acceptance. Furthermore, we analyzed each subscale of the IPPA-R, the instrument we have used for parents and peer attachment measurement, in regards to cyberbullying victimization through unconditional self acceptance. We have also analyzed if gender and age could be taken into consideration as moderators in this model. The analysis has been performed on 653 adolescents aged 11-17 years old from Romania. We used structural equation modeling, working in R program. For the fidelity analysis of the IPPA-R subscales, USAQ, and Cyberbullying Test, we have calculated the internal consistency index, which varies between .68-.91. We have created 2 models: the first model including peer alienation, peer trust, peer communication, self acceptance and cyberbullying victimization, having CFI=0.97, RMSEA=0.02, 90%CI [0.02, 0.03] and SRMR=0.07, and the second model including parental alienation, parental trust, parental communication, self acceptance and cyberbullying victimization and had CFI=0.97, RMSEA=0.02, 90%CI [0.02, 0.03] and SRMR=0.07. Our results were interesting: on one hand, cyberbullying victimization is predicted by peer alienation and peer communication through unconditional self acceptance. Peer trust directly, significantly, and negatively predicted the implication in cyberbullying. In this regard, considering gender and age as moderators, we found that the relationship between unconditional self acceptance and cyberbullying victimization is stronger in girls, but age does not moderate the relationship between unconditional self acceptance and cyberbullying victimization. On the other hand, regarding the degree of cyberbullying victimization as being predicted through unconditional self acceptance by parental alienation, parental communication, and parental trust, this hypothesis was not supported. Still, we could identify a direct path to positively predict victimization through parental alienation and negatively through parental trust. There are also some limitations to this study, which we've discussed in the end.

Abstract:

This paper offers a reflective and reflexive examination of the lived reality of a group of young white, working-class males engaging in secondary education in England at a time when this population is widely recognised as the lowest attaining ethnic group within British schools. The focus of the paper is an exploration of the development of identities and aspirations alongside contemporary demographic shifts in the British population within the intersection of neoliberal education policies and the emerging ideological conflict between identity conservatism and liberalism. The construction and performance of intersecting social-class, gender, ethnic and national identities are considered, as well as the process through which socially constructed narratives inform identities and aspirations. Evocative autoethnography is then employed to offer reflections on working-class habitus and, in particular, classed and gendered codes that underpin expectations of manhood in post-industrial culture within an education system which seemingly requires the abandonment of aspects of a working-class background, affiliation, and identity. Findings from the study identify the emergence of a culture of hyper-individualisation amongst white, working-class males in schools and a belief in the meritocratic ideologies of the New Right. In particular, the breakdown of the social contract, including notions of political and civic responsibility, coupled with the symbolic violence perpetrated against working-class culture and solidarity in British schools, have all informed the construction of working-class masculinity which values the individual entrepreneur over the collective and depoliticizes students to an extent where a focus on the spectacle and performance of success has replaced individual and collective investment in community.

The main sources of stress among college students are: changes in sleeping and eating habits, undertaking new responsibilities, and financial difficulties as the most common sources of stress, exams, meeting new people, career decisions, fear of failure, and pressure from parents, transition to university especially if it requires leaving home, working with people that they do not know, trouble with parents, and relationship with the opposite sex. The students use a variety of stress coping strategies, including talking to family and friends, leisure activities and exercising. The Yerkes–Dodson law indicates while a moderate amount of stress may be beneficial for performance, too high stress will result in weak performance. In other words, if students are too stressed, they are likely to have low academic performance. In a preliminary study conducted in 2017 with engineering students enrolled in three high failure rate classes, the majority of the students stated that they have high levels of stress mainly for academic, financial, or family-related reasons. As the second stage of the study, the main purpose of this research is to investigate the students’ level of stress, sources of stress, their relationship with student demographic background, students’ coping strategies, and academic performance. A device is being developed to gather data from students breathing patterns and measure their stress levels. In addition, all participants are asked to fill out a survey. The survey under development has the following categories: exam stressor, study-related stressors, financial pressures, transition to university, family-related stress, student response to stress, and stress management. After the data collection, Structural Equation Modeling (SEM) analysis will be conducted in order to identify the relationship among students’ level of stress, coping strategies, and academic performance.

Abstract:

Macau is known as the Oriental Monte Carlo and its economy depends on gambling heavily. The dealer is the key position of the gambling industry, at the end of the fourth quarter of 2015, there were over 24,000 dealers among the 56,000 full-time employees in gambling industry. More than half of dealers were female. The dealer is also called 'Croupier', the main responsibilities of them are shuffling, dealing, processing chips, rolling dice game and inspecting play. Due to the limited land and small population of Macao, the government has not allowed hiring foreign domestic dealers since Macao developed temporary gambling industry. Therefore, local dealers enjoy special advantages but also bear the high stresses from work. From the middle of last year, with the reduced income of gambling, and the decline of mainland gamblers as well as VIP lounges, the working time of dealers increased greatly. Thus, many problems occurred in this condition, such as the rise of working pressures, psychological pressures and family-responsibility pressures, which may affect job satisfaction as well. Because of the less research of dealer satisfaction, and a lack of standing on feminine perspective to analyze female dealers, this study will focus on investigating the relationship between working pressure and job satisfaction from feminine view. Several issues will be discussed specifically: firstly, to understand current situation of the working pressures and job satisfactions of female dealers in different ages; secondly, to research if there is any relevance between working pressures and job satisfactions of female dealers in different ages; thirdly, to find out the relationship between dealers' working pressures and job satisfactions in different ages. This paper combined qualitative approach with quantitative approach selected samples by convenient sampling. The research showed the female dealers from diverse ages have different kinds of working pressures; second, job satisfactions of the female dealers in different ages are dissimilar; moreover, there is negative correlation between working pressure and job satisfaction of female dealer in different ages' groups; last but not the least, working pressure has a significant negative impact on job satisfaction. The research result will provide a reference value for the Macau gambling business. It is a pattern to improve dealers' working environment, to increase employees' job satisfaction, as well as to offer tourists a better service, which can help to attract more and more visitors from a good image of Macau gaming and tourism.

Abstract:

Extending the working life of older workers is one important strategy in alleviating the social and economic challenges associated with the ageing population. The Australian government has implemented several strategies to improve the participation rates of older workers, however, the success of these initiatives has been limited. The aim of this project is to identify what workplace practices influence the workforce participation decisions of older workers. Thirty semi-structured interviews were conducted with older Australians who were either recently retired or currently working. Participants were asks about the factors that influenced their decision to retire/continue working and their current (or former) workplace practices. The results of the thematic analysis identified several factors which either supported (i.e., job autonomy and managerial support) or hindered (i.e., perceptions of age discrimination and age-based stereotypes) continued workplace participation. This research has several important applications for organisation managing intergenerational workforces, as well as policy makers interested in increasing the working life of ageing workers.

Abstract:

The topic of this article is to exploring the potentialities of a powerful optimization technique, namely Semidefinite Programming, for solving NP-hard problems. This approach provides tight relaxations of combinatorial and quadratic problems. In this work, we solve the maximum clique problem using this relaxation. The clique problem is the computational problem of finding cliques in a graph. It is widely acknowledged for its many applications in real-world problems. The numerical results show that it is possible to find a maximum clique in polynomial time, using an algorithm based on semidefinite programming. We implement a primal-dual interior points algorithm to solve this problem based on semidefinite programming. The semidefinite relaxation of this problem can be solved in polynomial time.

Abstract:

School violence is a global phenomenon that affects one of the core institutions of modern society to some degree across many countries, and on a global scale. Within this context, this study explores the impact of parental control on perpetrators of cyber bullying as a form of school-based violence in high schools in uMgungundlovu district of KwaZulu-Natal province in South Africa. Insights for this study were drawn from 18 in-depth interviews and two (2) focus group forums. The key themes that emerged from the findings include: (1) Parents are ignorant of their children involvement in cyber-crimes (2) Parents cannot adequately monitor what their children do on their cell phones (3) Female learners are the most affected as victims of cyber-crime.

Abstract:

An analysis of the distribution of nurses’ working time constitutes vital information for the management in planning employment. The objective of the study was to analyze the distribution of nurses’ working time in an emergency department. The study was conducted in an emergency department of a teaching hospital in Lublin, in Southeast Poland. The catalogue of activities performed by nurses was compiled by means of continuous observation. Identified activities were classified into four groups: Direct care, indirect care, coordination of work in the department and personal activities. Distribution of nurses’ working time was determined by work sampling observation (Tippett) at random intervals. The research project was approved by the Research Ethics Committee by the Medical University of Lublin (Protocol 0254/113/2010). On average, nurses spent 31% of their working time on direct care, 47% on indirect care, 12% on coordinating work in the department and 10% on personal activities. The most frequently performed direct care tasks were diagnostic activities – 29.23% and treatment-related activities – 27.69%. The study has provided information on the complexity of performed activities and utilization of nurses’ working time. Enhancing the effectiveness of nursing actions requires working out a strategy for improved management of the time nurses spent at work. Increasing the involvement of auxiliary staff and optimizing communication processes within the team may lead to reduction of the time devoted to indirect care for the benefit of direct care.

Abstract:

The dual energy computed tomography (DECT) aims at noting the HU(V) values for the sample at two different voltages V=V1, V2 and thus obtain the electron densities (ρe) and effective atomic number (Zeff) of the substance. In the present paper, we aim to obtain a numerical algorithm by which (ρe, Zeff) can be obtained from the HU(100) and HU(140) data, where V=100, 140 kVp. The idea is to use this inversion method to characterize and distinguish between the lipid and fibrous coronary artery plaques.With the idea to develop the inversion algorithm for low Zeff materials, as is the case with non calcified coronary artery plaque, we prepare aqueous samples whose calculated values of (ρe, Zeff) lie in the range (2.65×1023≤ ρe≤ 3.64×1023 per cc ) and (6.80≤ Zeff ≤ 8.90). We fill the phantom with these known samples and experimentally determine HU(100) and HU(140) for the same pixels. Knowing that the HU(V) values are related to the attenuation coefficient of the system, we present an algorithm by which the (ρe, Zeff) is calibrated with respect to (HU(100), HU(140)). The calibration is done with a known set of 20 samples; its accuracy is checked with a different set of 23 known samples. We find that the calibration gives the ρe with an accuracy of ± 4% while Zeff is found within ±1% of the actual value, the confidence being 95%.In this inversion method (ρe, Zeff) of the scanned sample can be found by eliminating the effects of the CT machine and also by ensuring that the determination of the two unknowns (ρe, Zeff) does not interfere with each other. It is found that this algorithm can be used for prediction of chemical characteristic (ρe, Zeff) of unknown scanned materials with 95% confidence level, by inversion of the DECT data.
