To deal with an uncertain future, global ethics as an academic endeavour might consider a common value we all share, such as sustainability, which acts as an all-encompassing term to indicate our future direction. Technologies of the near future that are currently in development hold problems and promise, and are clear subjects for the ethics of sustainability at a global level. Autonomous military combat robots, insects as food (entomophagy) and in vitro synthetically grown meat are significant cases. Such robots might in fact serve injustice and work against sustainability, and such novel food technologies may hold hope for promoting sustainability and global justice.  相似文献

We examined whether the power of tests as learning events, frequently demonstrated in the laboratory, would also occur in a large undergraduate course. Our goals were to determine: if learning of information tested on multiple-choice quizzes administered across the course would be enhanced compared to non-tested control information; and what the effects of quizzing would be for the learning of information conceptually related to the tested information but not itself tested on the quizzes. Given that retrieval practice can have positive (testing effect) and negative consequences (retrieval-induced forgetting), our concern was that the learning and later retention of non-tested conceptually related information might be impaired by the multiple-choice quizzes. Importantly, learning benefits were found for both types of information on the final exam, indicating that quizzing within a course can enhance not only the learning of specifically tested information, but the learning of non-tested conceptually related information as well.  相似文献

Multiple studies indicated that children raised to be spiritual were found to be happier, have more resilience and positive outlook towards life events. This paper attempts to explore and integrate the value of spirituality and religious practices. It is approached through the understanding and application of the tawakkul (trust in God) concept, as perceived from an Islamic viewpoint. This aspect is explored through the consolidation of the ‘believing in God’ component, as highlighted in the National Philosophical Foundations in Brunei, Indonesia and Malaysia to tawakkul. It will further seek to find the prospect of empowering Muslim children’s spirituality through such integration. This theoretical paper is based on the Islamic foundations and characteristics; its implementation and implications. The outcome illustrates indication of ‘divine involvement’ as the main essence of tawakkul; resulting sustainable religious, spiritual and moral enhancement. Moreover, an internalised and implicit form of tawakkul should be encouraged to promote self-understanding.  相似文献

Depression and anxiety are hightly prevalent among patients with Type 2 Diabetes (T2D), however not commonly related to outcomes, treatment and comorbidities. Eating behaviors could also have an implication. To evaluate the relation between mood and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D we conducted this exploratory cross sectional study in a population from Mexico. Hospital Anxiety and Depression Scale and the Three Factor Eating Questionnaire Revised 21 (TFEQ-R21) were correlated with age, gender, blood pressure, treatment and comorbidities (nephropathy, neuropathy, retinopathy and cardiopathy). Multi-linear regression models and 2k factorial analyses were conducted. Sixty-one patients (31 male) 55 years old (SD 13) with at least 5 years of T2D were included. Anxiety correlated with depression (r = 0.25, p < 0.05). Gender (women) (std B 0.026, p < 0.001), insulin therapy (std B 0.3, p = 0.11), systolic blood pressure (std B 0.263, p = 0.02) and cardiovascular disease (std B 0.232, p = 0.035) predicted depression. Insulin therapy had a positive effect in cognitive restraint. (std B 0.32, p = 0.001). Age (std B 0.37, p = 0.003) and systolic blood pressure (std B 0.237, p = 0.048) predicted positively emotional eating (not previously published). 2k factorial analyses proved additive interaction between complications and insulin therapy with depression. This study supports the relation between mood disorders and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D and the additive interaction between factors and mood disorders.  相似文献

The objective of this paper was to streamline the case for Muslim same-sex unions that was comprehensively made in Jahangir and Abdullatif (2016). Additionally, we try to address same-sex unions on the basis of non-binary gender, gender expression and sexual orientation. Based on our work, we argue that the case for Muslim same-sex unions can be made on the basis of broad principles of human dignity and affection and therefore through marriage or through the specific arguments of repelling harm and legal authority. In this regard, going beyond the overarching Islamic value of human dignity, we specifically argue that the case for same-sex unions can be anchored on verse 4:28 on facilitating a legal outlet for sexual expression.  相似文献

The New Jersey Graduated Driver License (GDL) restrictions were updated in 2010 with changes that included a more active role of parents monitoring practice driving with their teens. In addition to extending the driving phases, there were new curfew and passenger limit restrictions. Teen drivers were also required to use red decals on license plates to identify themselves as inexperienced drivers. The Division of Highway Traffic Safety had partnered with the Motor Vehicle Commission in the past to produce practice driving guides for parents of teen drivers, but recognized the need to support this type of informational campaign with an educational program for helping parents to understand changes in the GDL and recognize the importance of their role in the GDL monitoring process. In 2010, the New Jersey Parent/Teen Driver Orientation program was developed to educate parents of teen drivers on the new GDL restrictions and Children’s Hospital of Philadelphia (CHOP) findings concerning the importance of parenting roles in teen driver safety. Additional resources were incorporated into the orientation that included the Centers for Disease Control (CDC) community based information and the University of Michigan Transportation Research Institute (UMTRI) parent-teen driver contracts.This community-based training, known as the New Jersey Parent/Teen Driver Orientation was later renamed Share the Keys, and had been developed for the state as a component of the New Jersey Highway Safety grant received by Kean University. The comprehensive program was designed to engage parents, teens, educators, and law enforcement in the teen driving process and help parents to understand how personal parenting styles and engagement may impact teen crash risk and compliance with the GDL restrictions. Local representatives from traffic safety and law enforcement teamed with school officials and driver education teachers to present programs in their communities. The evaluation process was built into the program as a pre-survey administered at the beginning of the session, a post-survey completed directly afterward, and a voluntary follow-up survey completed on line or mailed, beginning six months later.Evidence from the first year showed that parents maintained a significant level of engagement throughout the GDL process with their teen drivers. However, findings did establish the need to further examine why Authoritative parenting styles had declined, especially since this parenting approach was considered in the literature as most effective in reducing teen crash risks. Therefore, the scope of this study was broadened to a three year effort that reached over 2800 parents and investigated behavioral outcomes impacted by Share the Keys. While comparisons made between driving phases and parenting styles had yielded no significant results, changes within parenting style scores were shown to be effective over time. The reported levels of Permissive and Uninvolved parents remained consistent throughout all three driving phases, while Authoritarian parenting peaked during the Probationary phase, and Authoritative parenting was noted as highest once teens earned their license.  相似文献

Empathy is a foundational, necessary component of successful counseling. Relaying an understanding of empathy, including the components and science behind the phenomenon, is critical to the development of counselors-in-training. In addition, creative practice is a pillar of professional counseling, and is linked to experiential learning and meaningful integration of new knowledge in counselor education. The purpose of this article is to provide a review of the definitions of empathy, provide current literature on the science of empathy, and discuss specific creative interventions to use within counseling courses to increase empathic knowledge and skills.  相似文献

The purpose of this qualitative study is to understand staff members’ and administrators’ perceptions of group-based music therapy in an acute care mental health setting. The researcher conducted semi-structured interviews with six experienced administrators and unit staff who were familiar with music therapy. Using an inductive approach to thematic analysis, the author identified six themes: (a) music constitutes an important role in patients’ lives, (b) patient-centricity and competence of the music therapist, (c) music therapy uniquely engages the patient with music, the music therapist, and peers, (d) music therapy shifts patients’ focus from internal to external, (e) music therapy is a normalizing experience that facilitates interaction, and (f) music therapy provides optimal conditions for cognitive, affective, and behavioral change. Implications for clinical practice, suggestions for future research, and limitations of the study are provided.  相似文献
