Students' sustainability consciousness with the three dimensions of sustainability:Does the locus of control play a role?

The persistent environmental problems and the growing difficulty to achieve sustainable development require a re-evaluation of person’ sustainable knowledge, attitude, and behaviour. To go to where we want to go, we must first assess where we are now. The study investigated the level of sustainability consciousness of students in India, and sustainability consciousness was expressed in sustainability knowledge, attitude, and behaviour. Sustainability consciousness was further examined using the three dimensions, such as environment, society, and economy. By drawing the perception map of students and studying the role of the locus of control, the reasons why sustainability knowledge does not appear in sustainability behaviour were analyzed. Quantitative analysis was conducted for a sample of 205 students from higher educational institutions across central India(Madhya Pradesh) from January to March in 2022. The data were analyzed using the SPSS 26 and Smart Partial Least Square(PLS) 3.0. The research revealed that sustainability attitude impacts sustainability behaviour more than sustainability knowledge. The results showed that respondents’ sustainability knowledge is higher than their sustainability attitude and behaviour. Moreover, it was discovered that economic concerns can lead to sustainability behaviour. In order to study respondents’ behaviour regarding sustainability consciousness, the study divided respondents into two groups according to the locus of control: the internal and external locus of control. It was found that most respondents thought whatever happened around them was beyond their control. Further, the locus of control influenced sustainability behaviour in groups with the internal locus of control. The study helps to explain why sustainability knowledge and attitude cannot translate into sustainability behaviour and provides a basis for achieving sustainable development. The conclusions of this study are crucial for governments, educational institutions, and organizations that empower youth to change their behaviour.

Multiple mediation effects of health locusof control and hope on the relationshipbetween stroke patients’ social supportand self-management

Objective:This study aimed to identify the mediation effects of health locus of control(HLC)and hope between stroke patients’social support and self-management.Methods:A cross-sectional study was conducted.A total of 300 Chinese stroke patients were recruited by convenient sampling from the acupuncture department of two Chinese Traditional Medical Hospitals in Tianjin Province from June to September 2018.The self-report questionnaires include Social Support Assessment Scale,Herth Hope Index,Mental Health Locus of Control Scale,Stroke Self-management Behavior Scale,and personal information questionnaires.All the survey data were entered in Excel and analyzed using the SPSS 24.0 program.Mediation was tested with Bootstrapping in AMOS 23.0 program.Results:The result showed that internal health locus of control(IHLC),chance health locus of control(CHLC)and hope were the mediators between social support and self-management.The direct,indirect,and total effects of social support on self-management behavior were 0.306 (P<0.01),0.109(P<0.01),and 0.415(P<0.01),respectively.Conclusions:Social support can directly influence self-management,and it can also indirectly influence self-management through IHLC,CHLC,and hope.

Correlates of Health Locus of Control among Patients Diagnosed with Type-II Diabetes Mellitus

Background: The comorbidity between chronic physical conditions and psychosocial health became common interest for health professional and researchers. The purpose of this study was to investigate the relationship among health locus of control, self efficacy, and demographic factors in patients with type-II diabetes mellitus. Method: Data were collected using cross-sectional, correaltional design from 793 patients with type-II diabetes in regards to health locus of control (HLOC) self-efficacy, and biomarkers. Results: The mean score for the internal subscale of HLOC was 27.2 (SD = 6.32), for the powerful others subscale of HLOC it was 30.9 (SD = 5.7), and for chance subscale of HLOC it was 18.6 (SD = 6.8). The mean total score of locus of control scale was 76.8 (SD = 13.1) ranging from 19 to 132. The mean score of HbA1C was 7.5 (SD = 2.6). Patients had moderate to high perception of powerful other health locus of control, and self efficacy. Results also showed that locus of control had positive and significant correlation with self efficacy (r = 0.18, p > 0.01) and negative relationship with HbA1C (r = -0.11, p > 0.01). On the other hand, age has no significant correlation with health locus of control. Conclusion: Health care professionals need to enhance patient’s self-efficacy and internal power of their patients for better health outcomes. Nurses and other health professionals need to emphasize the psychosocial health aspects of patients with chronic illnesses, and in particular, those diagnosed with type-II diabetes mellitus.

Japanese Version of the Parent Health Locus of Control Scales: Validity and Reliability

The Parent Health Locus of Control (PHLOC) Scales measure parents’ beliefs about the factors that affect their children’s health. The aim of our study was to develop a Japanese version of the Parent Health Locus of Control (JPHLOC) Scales and to verify its validity and reliability. The JPHLOC scales consist of six scales: Professional Influence, Parental Influence, Child Influence, Media Influence, Fate Influence, and God, Buddha, and the Spirits Influence. Our questionnaire was administered to 231 principal caregivers from Japan whose children were under 6 years of age. The items, related to the “God, Buddha, and the Spirits Influence” scale, showed a floor effect. The exploratory factor analysis indicated that JPHLOC’ six factors functioned similarly to the PHLOC’ factors. The Fate Influence and Child Influence factor structures in JPHLOC scales were different from the corresponding factor structures in the original PHLOC scales in the functioning of only one item. There were statistically significant correlations between JPHLOC scales and Japanese version of the Parenting Stress Index-Short Form (PSI-SF), which add evidence to the criterion-related validity of JPHLOC scales. Furthermore, applying the known-groups method, our study showed that there was a significant difference across the JPHLOC scale scores, owning to differences in the children’s and caregivers’ demographics, which provides an evidence for construct validity. The Cronbach’s alpha coefficients for the six scales were estimated between 0.73 and 0.93. In a test-retest study, the interclass correlation coefficients for the six scales were ranged between 0.80 and 0.90. The results suggested that the JPHLOC scales have sufficient reliability and validity. The JPHLOC scales are applicable to the caregivers of healthy children. We confirm that the PHLOC scales are also applicable to Japanese caregivers.

Locus of Control Theory,Productivity,Job Satisfaction,and Procrastination:A Systematic Literature Review in the Organizational Context of the 21st Century

Locus of control theory,which was developed by Rotter,suggests that there are two main types of peoples’behaviors when attributing their failure or success of their life events:external locus of control and internal.The way that individuals act is determined by their expectations of their specific behaviors and the value that they add to these expectations.For instance,people who fit in the internal category are more likely to attribute their life events to their own behaviors,skills,and attitudes,while people who fit in the external category,tend to attribute their acts to fate,chance,and other exterior factors that are out of their control.The aim of this systematic literature review was to define the fundamental concept of LOC theory,to investigate major findings of the theory in accordance with LOC and procrastination,job satisfaction,and performance and lastly,to discuss the practical use of the theory in the organizational context.

Relationship between Locus of Control and Academic Achievement of Secondary School Students in Abia State

The study intended to determine the relationship between locus of control and academic achievement of secondary school students. Some students have been observed to achieve higher while some achieve lower even after being exposed to the same subject matter by the same instructor. The objective of the study was to determine if locus of control correlated with academic achievement of students as moderated by gender and school-type. The study was anchored on attribution theory. The study adopted a correlational research design. A total of 388 SS3 students in Aba Education zone were selected using purposive and simple random sampling techniques. Instruments for data collection were an adopted LOC scale and students’ exam scores in Mathematics, English and CRS. To determine the reliability of the instrument, Kuder-Richardson reliability test (KR-20) was employed and an overall coefficient of 0.76 was obtained for LOC scale. Data were analyzed using Pearson Product Moment Correlation Coefficient. Results showed significant relationship between locus of control and academic achievement of male students. Results also showed significant relationship between locus of control and academic achievement of public school students. Based on the findings, it was recommended that school authority should encourage good performance by rewarding students with excellent performance, because when good behaviour is rewarded, the individual is motivated to do better. Also, government should also provide the schools with necessary infrastructures that would make teaching and learning very interesting.

工作场所隐私缺失会导致工作脱离行为吗?———一项基于情感事件理论的研究

越来越多的企业开始采用开放式和共享式的办公空间设计,而开放式和共享式办公空间设计导致的一个关键问题就是办公场所隐私缺失。本研究基于情感事件理论,通过对210名员工进行时间间隔为两周的两阶段问卷调查,探析了工作场所隐私缺失会怎样通过消极情绪影响到员工的工作脱离行为。最终得到的研究结果表明:工作场所隐私缺失会对员工的工作脱离行为产生显著的正向影响,消极情绪在两者之间发挥部分中介作用。此外,控制点调节了工作场所隐私缺失与消极情绪之间的关系:相较于内控制点个体,外控制点个体更容易受到工作场所隐私缺失的消极影响,其消极情绪的增加更为明显,对工作脱离行为的影响也更强烈。

Mapping epistasis and environment × QTX interaction based on four-omics genotypes for the detected QTX loci controlling complex traits in tobacco

Using newly developed methods and software, association mapping was conducted for chromium content and total sugar in tobacco leaf, based on four-omics datasets. Our objective was to collect data on genotype and phenotype for 60 leaf samples at four developmental stages, from three plant architectural positions and for three cultivars that were grown in two locations. Association mapping was conducted to detect genetic variants at quantitative trait SNP(QTS) loci, quantitative trait transcript(QTT) differences,quantitative trait protein(QTP) variability, and quantitative trait metabolite(QTM) changes,which can be summarized as QTX locus variation. The total heritabilities of the four-omics loci for both traits tested were 23.60% for epistasis and 15.26% for treatment interaction.Epistasis and environment × treatment interaction had important impacts on complex traits at all-omics levels. For decreasing chromium content and increasing total sugar in tobacco leaf, six methylated loci can be directly used for marker-assisted selection, and expression of ten QTTs, seven QTPs and six QTMs can be modified by selection or cultivation.
