Public Enterprise Reform in Fiji Islands

Reforming the public sector has been on the agenda of nations throughout the world since the late 1970s. Fiji is no exception. It has embarked on reforming its commercial and industrial enterprises since the late 1980s. The government of Fiji has reformed most of its enterprises with an avowed objective of enhancing profitability, productivity, efficiency and accountability. This paper makes an attempt to share some of the experiences of public enterprise reform process in Fiji. It aims to analyze the background, process, contents and impact of the reform and examine the factors impeding the reform program. It highlights that (a) both internal and external factors were responsible for introducing reforms; (b) the reform efforts have not been able to produce desired results; (c) the structural inadequacies in institutions and organizations have created bottlenecks in the reform process; and (d) uncertainty in the political sphere has contributed further to policy shifts.     

儿童玩具礼品包装设计的研究与思考

现如今礼品类高端产品由于自身的品牌效应，得到了市场上极高的受欢迎指数，因其包装精美和视觉鲜明的因素，越是在国际市场环境低迷的时候，越容易抢占市场。在中国的儿童玩具礼品领域，不单单需要效仿国际流行的设计趋势，而且还要积极提升国内自主品牌影响力，这才是中国当今发展儿童玩具礼品包装产业，缩小与国际水平之间的差距，夺回本土市场继而进军国际市场的必由之路。具体分别从消费群体和包装设计本身两方面进行调查和分析研究。     

大学内部的利益冲突与组织决策——以某地方综合性大学旧房改造项目为例

本案例中，大学的规章制度与组织结构规定了参与旧房改造项目相关决策的群体和机构以及做出相关决策所需要的步骤与程序，也规定了不同群体在这一决策过程中的不同地位和可能拥有的资源，甚至是他们的决策倾向；旧房改造项目的冲突根源在于计划经济体制向市场经济体制转型过程中大学内部出现的不同群体的利益分化，但值得注意的是，这些不同群体的利益冲突却是以质疑相关环节上决策者行为的合法性为中心展开的，而关于合法性的争议则更多地涉及了对相关行为的价值意义的解释。     

Women's participation in self‐help groups as a pathway to women's empowerment: A case of Nepal

Non‐governmental organizations (NGOs) and the government of Nepal have made some effort to reduce poverty in Nepal by creating women's affiliation groups, some of which are micro‐credit organizations. Using capabilities as defined by Amartya Sen (Development as freedom, Oxford University Press, New Delhi, 2000), which includes employment opportunities, women's ownership in productive resources such as land and/or homes, educational opportunities, and women's participation in decision‐making in the family, this study evaluated the extent to which women's ethnic group or caste affiliation affected a woman's likelihood of being empowered by participation in these groups. We analyzed a sample of 8,973 women which was taken from the 2011 Nepal Demographic and Health Survey. Previous research has demonstrated that participation in gender‐based groups is correlated with higher economic status. This study adds to the literature on women's affiliation groups by investigating the impact of structural factors, such as caste and ethnicity, on women's self‐help group participation (women's groups and credit groups).     

Agreements About Extra-Dyadic Sex in Gay Men's Relationships: Exploring Differences in Relationship Quality by Agreement Type and Rule-Breaking Behavior

Research comparing the quality of monogamous and non-monogamous (“open”) relationships among gay men has produced mixed findings. In addition, little is known about the consequences of breaking the rules of relationship agreements about extra-dyadic sex. Results from a survey of 229 gay men in romantic relationships showed that open relationships were less passionate, but no less intimate or committed, than monogamous or “threesome-only” relationships. However, men who broke rules reported lower relationship quality overall, regardless of the relationship agreement. Thus, it is less the nature of the agreement itself than adhering to the conditions of it that influences relationship quality.     

Bayesian adaptive dose‐escalation designs for simultaneously estimating the optimal and maximum safe dose based on safety and efficacy

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs.     

The “Silent Dog” Method: Analyzing the Impact of Self-Generated Rules When Teaching Different Computer Chains to Boys with Autism

The purpose of the study was to extend the literature on verbal self-regulation by using the “silent dog” method to evaluate the role of verbal regulation over nonverbal behavior in 2 individuals with autism. Participants were required to talk-aloud while performing functional computer tasks.Then the effects of distracters with increasing demands on target behavior were evaluated as well as whether self-talk emitted by Participant 1 could be used to alter Participant 2''s performance. Results suggest that participants'' tasks seemed to be under control of self-instructions, and the rules generated from Participants 1''s self-talk were effective in teaching computer skills to Participant 2. The silent dog method was useful in evaluating the possible role of self-generated rules in teaching computer skills to participants with autism.
