Defensive dining: notes on the public dining experiences in Singapore

This paper examines the relationship between an individual’s degree of religiosity (or piety) and his/her participation in everyday life in a secular, cosmopolitan and multicultural society such as Singapore, by focusing on the practice of public dining. Given that Islam has dietary restrictions (‘halal’), this paper hypothesizes that a devout Muslim might be placed in a situation of considerable unease when dining publicly, as the external environment may conflict with these restrictions. The research for this paper involved interviews with 20 Singaporean Muslims, who have described themselves as being ‘devout’ and ‘practicing’, asking about their views on dining at public food courts or hawker centers. It finds that rather than choosing to avoid these situations, they engaged in a series of defensive strategies to accommodate their religious obligations as well as intercultural interactions, to a certain degree. This paper concludes that because deeply religious Muslims in Singapore implement ‘defensive dining,’ concerns about self-exclusion, isolationism and separatism are probably unfounded, as these individuals appear willing to participate in multicultural and cosmopolitan everyday life.     

Varying Responsibilities Across Job & Home Domains and Employee Well Being

This study is aimed at signifying the importance of the management of employee well being. We identify that when individuals are involved in different roles at job and at home, such interaction affects the wellbeing of employees. Specifically, the effect of work family conflict and facilitation on employee satisfaction is studied. Data was collected from a sample of 291 employees of different organizations in the service sector. Structured equation modeling was used to test the fit of two proposed models and to validate the hypothetical relationships among the study variables. Both, job and home directions, of work family conflict and facilitation were found related to satisfaction at job and at home. The results indicate that the management of work family conflict and facilitation is inevitable for ensuring the well being of employees.     

Commentary on Paper by Steven Cooper

In this discussion of Steven Cooper's paper, it is argued that, although Cooper's desire to hold himself “accountable” in his work with patients is laudable, the “pluralistic third” approach that he employs gives rise in his doing so to several difficulties in the way that it is described in the paper. The vivid clinical material that Cooper provides to illustrate his approach is used as a starting point to offer an understanding of what transpired between analyst and patient, which although convergent with Cooper's formulations in some respects nevertheless follows a very different line of thinking in other areas. Broadly speaking, it is suggested that although these divergences arise from many sources—a discussion of which is beyond the scope of this contribution—one particular issue involved is a rather different understanding of the role of early internalized object relations in the patient's psychic life and the way these get lived out at many levels in the treatment situation. It is further argued that Cooper's conceptualization of the approaches of schools different from his own appears somewhat circumscribed and this detracts from his desire to make an authentic comparison between his way of working and those of other schools, something that is called for by his proposed pluralistic third method of keeping himself accountable. This is not considered surprising given the difficulties inherent in our becoming adequately familiar, in more than just an intellectual way, with the approaches of schools different from our own, especially when wide divergences are involved between schools.     

The ʿUlamāʾ, Fatāwā and Challenges to Democracy in Contemporary Indonesia

This article examines the fatāwā issued by the Council of Indonesian ?ulamā? (Majelis Ulama Indonesia; MUI) regarding democracy, pluralism and religious minorities and explores their socio-historical contexts. The MUI emerges as having an ambiguous attitude towards democracy. The 1998 reform in Indonesia offered a backdrop that encouraged the MUI to be more independent from the state. This enabled the MUI to produce Islamic religious discourses that intersect with democracy, civil society, law enforcement, human rights, public security and elections. The MUI has accepted several principles that are prerequisites for a democratic society and state, such as equality before the law, good governance, protection of human rights, maintenance of public peace and security, and participation in fair elections. However, the Council is very conservative when comes to safeguarding Islamic faith and theology. It rejects pluralism, religious freedom and Muslim minorities such as the Ahmadiyya. The MUI's strict interpretation of Islam and support for Islamist ideology and conservatism prevent it from accepting democracy fully.     

Attenuated response to methamphetamine sensitization and deficits in motor learning and memory after selective deletion of β-catenin in dopamine neurons

In the present study, we analyzed mice with a targeted deletion of β-catenin in DA neurons (DA-βcat KO mice) to address the functional significance of this molecule in the shaping of synaptic responses associated with motor learning and following exposure to drugs of abuse. Relative to controls, DA-βcat KO mice showed significant deficits in their ability to form long-term memories and displayed reduced expression of methamphetamine-induced behavioral sensitization after subsequent challenge doses with this drug, suggesting that motor learning and drug-induced learning plasticity are altered in these mice. Morphological analyses showed no changes in the number or distribution of tyrosine hydroxylase-labeled neurons in the ventral midbrain. While electrochemical measurements in the striatum determined no changes in acute DA release and uptake, a small but significant decrease in DA release was detected in mutant animals after prolonged repetitive stimulation, suggesting a possible deficit in the DA neurotransmitter vesicle reserve pool. However, electron microscopy analyses did not reveal significant differences in the content of synaptic vesicles per terminal, and striatal DA levels were unchanged in DA-βcat KO animals. In contrast, striatal mRNA levels for several markers known to regulate synaptic plasticity and DA neurotransmission were altered in DA-βcat KO mice. This study demonstrates that ablation of β-catenin in DA neurons leads to alterations of motor and reward-associated memories and to adaptations of the DA neurotransmitter system and suggests that β-catenin signaling in DA neurons is required to facilitate the synaptic remodeling underlying the consolidation of long-term memories.     

Consequences of Supervisor Knowledge Hiding in Organizations: A Multilevel Mediation Analysis

Drawing on the theoretical framework of social cognitive theory, our study explores the multilevel mediation model in which moral disengagement (level-1) mediates the direct relationships between knowledge hiding by supervisors from subordinates (KHSS: level-2) and supervisor directed organizational citizenship behavior (SOCB: level-1) and supervisor directed silence (SS: level-1). Drawing on multi-sourced, multi-timed, and multilevel data of 306 subordinates nested within 83 supervisors, multilevel structural equation modeling (ML-SEM) was used to test the proposed model. The results demonstrate that KHSS, first, fosters subordinates’ moral disengagement, which in turn reduces their SOCB and enhances their SS. Our findings offer several useful theoretical and managerial implications of the negative consequences of supervisor knowledge hiding in organizations. As one of the first studies to provide empirical evidence for the existence of supervisor knowledge hiding (i.e. KHSS), this research highlights the consequences of KHSS on subordinates’ moral disengagement, SOCB, and SS.     

Changes in Muscle Activity in Response to Assistive Force during Isometric Elbow Flexion

Abstract

This study investigated the muscle activity and force variability in response to perturbation of assistive force during isometric elbow flexion. Sixteen healthy right-handed young men (age: 22.0?±?1.1?years; height: 171.9?±?4.8?cm; weight 68.4?±?11.2?kg) were recruited and the muscle activity of biceps brachii and triceps brachii were assessed using surface electromyography. Workload force and assistive force applied on isometric elbow flexion significantly affected the changes in both biceps and triceps muscle activities. A higher assistive force was shown to result in reduced biceps muscle activity compared to the unassisted period. In contrast, the efficiency of the assistive force acting on the biceps decreased as the assistive force increased. In general, the force variability of the biceps muscle remained approximately the same at lower workload force conditions than that at higher workload force conditions. In conclusion, higher assistive force may not yield a higher performance efficiency in human-assistive force interaction.
