Moral antecedents of smoking behavior and risk beliefs among overseas Asian students

Instead of focusing on the misconduct of multinational cigarette manufacturers, this research project broadens the discussion of cigarette consumption by focusing on the moral antecedent variables that shape young adults' smoking behavior and risk beliefs. It especially challenges current wisdom among anti-smoking advocates that by increasing consumer knowledge of the medical risks associated with smoking will lead to significant reductions in young adult smoking prevalence rates. Empirical results of this study suggest that although increasing smoking risk knowledge does not significantly reduce Asian students' smoking behavior, increasing their risk assessment beliefs does produce the desirable public policy effect of reducing current smoking. Furthermore, only among rules-driven individuals does an increase in no harm scores significantly reduce student smoking risk assessment beliefs. Thus, current anti-smoking advertising campaigns among overseas Asian students may be more effective if they attempt to change these students' smoking risks assessment beliefs especially if they are targeted to rules-driven student market segments.

Correlates of aggressive behavior in dementia

Background and Objective: A review of current literature was undertaken in order to summarize some of the possible biopsychosocial contributions to the development of aggressive behavior in elderly people with dementia. It was intended that such a summary would provide a useful clinical aid when assessing patients with behavioral symptoms and a starting point for undertaking research in this area. Method: Information was gathered from literature searches conducted on several occasions between 1995 and 2001 using 3 databases (Medline, CINHAL and PsycINFO), as well as journals and books available from the libraries of the authors and from Monash University, Melbourne, Australia. Results: Associations between various conditions and the development of aggressive behavior were found, including the contributions of degrees of cognitive impairment, personality, sensory change, physical illness, language impairment, brain pathology, affective and psychotic disorders. The role of gender, sexuality and disruption of circadian rhythms is also discussed, as is the importance of environmental factors. Conclusion: Identification of correlates of aggressive behavior may assist clinicians to understand and manage aggressive behavior more effectively.

Preparation and characterization of natural rubber/silica nanocomposites using rule of similarity in latex

Rule of similarity and latex compounding techniques were combined for the first time to prepare natural rubber/nanosilica (NR/SiO2) nanocomposite with core-shell nanosilica-poly (methyl methacrylate) (SiO 2-PMMA) particles and PMMA-modified natural rubber matrix (NR-PMMA). The microstructure of SiO2 and nanocomposites with different SiO 2 contents was characterized by fourier transform infrared spectroscopy (FTIR); the morphology of nanocomposites was investigated with scanning electron microscopy (SEM); the tensile strength was characterized by tensile testing machine and the thermal stability of composites was studied by thermal gravimetric analysis. Results showed that PMMA chains have successfully grafted onto the surface of SiO2, and the core-shell SiO 2-PMMA nanoparticles and NR-PMMA latex have been perfectly incorporated. SiO2-PMMA nanoparticles are evenly distributed over the NR matrix with an average size in the range of 60-100 nm at the low content (SiO2? 3 wt%), while aggregations are apparently observed when 5 wt% SiO2 is loaded. In addition, NR/SiO2 composities possess a considerable improvement in ageing resistance compared with the pure NR. The tensile strength of composite increases from 6.99 to 12.72 MPa, reaching the highest value at a 0.5 wt% SiO2 loading, and then the figure decreases gradually because of the aggregation of SiO2 nanoparticles. It is anticipated that the reported process is to provide a simple and economic way for preparing NR composites.

A Response to Critique of the Refreeze Step in Lewin’s Model of Organizational Change from the Viewpoint of Organizational Behavior

Problem Statement
This paper responds to criticism of Kurt Lewin’s three step model of organizational change in increasingly turbulent environments. It explores whether the refreeze step of Kurt Lewin’s notable three step model is still applicable to organizational change processes in the age of globalisation and digitalisation.

Method
Literature review and critical analysis of applied examples are used to provide an overview of Kurt Lewin’s three-step change model. Authors’ observations and reflections are integrated in the discussion. The changing contemporary environment and the implications for the refreeze step of Lewin’s model are accordingly discussed.

Conclusions
The paper concludes that a balance of stability and movement; of discrete and emergent change; is the reality for today’s organizations, and forms the touchstone for Lewin’s formulation of change theories. Alignment is observed between notions of desired equilibrium in Lewin’s model and the contemporary underpinnings of sustainability. Technology and the modern pace of organizational change are also factors to consider. There has hence been an adaptation of his theoretical heritage that is current and sufficiently robust to withstand the criticisms of the refreeze stage.

A study of phase behavior and conductivity of mixtures of the organic ionic plastic crystal N-methyl-N-methyl-pyrrolidinium dicyanamide with sodium dicyanamide

We report on the thermal, structural and conductivity properties of the organic ionic plastic crystal (OIPC) N-methyl-N-methyl-pyrrolidinium dicyanamide [C1mpyr][N(CN)2] mixed with the sodium salt Na[N(CN)2]. The DSC thermal traces indicate that an isothermal transition, which may be a eutectic melting, occurs at ~ 89 °C, below which all compositions are entirely in the solid phase. At 20 mol% Na[N(CN)2], this transition is the final melt for this mixture, and a new liquidus peak grows beyond 20 mol% Na[N(CN)2]. The III- > II solid-solid phase transition continues to be evident at ~- 2 °C. The microstructure for all the mixtures indicated a phase separated morphology where precipitates can be clearly observed. Most likely, these precipitates consist of a Na-rich second phase. This was also suggested from the vibrational spectroscopy and the 23Na NMR spectra. The lower concentrations of Na[N(CN)2] present complex 23Na MAS spectra, suggesting more than one sodium ion environment is present in these mixtures consistent with complex phase behavior. Unlike other OIPCs where the ionic conductivity usually increases upon doping or mixing in a second component, the conductivity of these mixtures remains relatively constant and above 10- 4 S cm- 1 at ∼ 80 °C, even in the solid state. Such high conductivities suggest these materials may be promising to be used for all solid-state electrochemical devices.

Prevalence of sedentary behavior in children under 2 years: a systematic review

Sedentary behavior has negative health outcomes, evident even in young children. Identifying the prevalence of sedentary behavior in children <2years is important for determining the necessity for intervention strategies. The aim of this systematic review was to determine the prevalence of sedentary behavior in children <2years. Medline, PsycINFO, SPORTDiscus, and Education Research Complete electronic databases were searched, as were reference lists of included articles and the authors' own collections. Inclusion criteria were: published in a peer-reviewed English language journal; mean age of children <2years; and a reported measure of the prevalence of sedentary behavior. Twenty-four studies met the inclusion criteria. Most studies used parent-reported screen time as the sedentary behavior measure; only one study reported time spent restrained (i.e., kept inactive) and no studies reported objectively assessed sedentary time. Estimates of young children's screen time ranged from 36.6 to 330.9min/day. The proportion of children meeting the zero screen time recommendation ranged from 2.3% to 83.0%. In conclusion, very little is known about sedentary behaviors other than screen time in this age group. Although highly variable, findings suggest that children are already engaging in high levels of screen time by age 2 and the majority exceed current recommendations.

The emergency powers in Bangladesh: means for subversion of the rule of law?

The Constitution of Bangladesh empowers the President to proclaim an emergency on the actual or imminent ground of war or external aggression or internal disturbance. However, the insertion of ‘internal disturbance’ in the Constitution as a ground for invoking emergency has provided the executive with the opportunity to proclaim all the five emergencies in Bangladesh on this vague ground for purposes other than that of securing the life of the nation. Furthermore, in the absence of any effective constitutional mechanisms for scrutinising the exercise of emergency powers and a time limit on the continuation of a state of emergency, some of the proclamations of emergency continued even after the alleged threat posed to the life of the nation was over to perpetuate the survival of the party in power by repressing any political threat to the regime. This Article, therefore, recommends for insertion in the Constitution of Bangladesh detailed norms providing for legal limits on the wide power of the executive concerning the proclamation, administration and termination of emergency with a view to ensure that emergencies can no longer be resorted to as the effective means of discarding the rule of law.
