The purpose of this paper is to propose a semiparametric estimator for the tail index of Pareto-type random truncated data that improves the existing ones in terms of mean square error. Moreover, we establish its consistency and asymptotic normality.

To construct a root mean squared error (RMSE)-reduced estimator of the tail index, the authors used the semiparametric estimator of the underlying distribution function given by Wang (1989). This allows us to define the corresponding tail process and provide a weak approximation to this one. By means of a functional representation of the given estimator of the tail index and by using this weak approximation, the authors establish the asymptotic normality of the aforementioned RMSE-reduced estimator.

In basis on a semiparametric estimator of the underlying distribution function, the authors proposed a new estimation method to the tail index of Pareto-type distributions for randomly right-truncated data. Compared with the existing ones, this estimator behaves well both in terms of bias and RMSE. A useful weak approximation of the corresponding tail empirical process allowed us to establish both the consistency and asymptotic normality of the proposed estimator.

A new tail semiparametric (empirical) process for truncated data is introduced, a new estimator for the tail index of Pareto-type truncated data is introduced and asymptotic normality of the proposed estimator is established.

The purpose of this paper is to assess the socioscientific issue (SSI) method as a way of improving seventh graders’ nutrition know-how on dietary supplements (DS), and to describe how students experience learning nutritional issues through the SSI method.

Participants were seventh graders from three different classes (n=43). Health education intervention lasted 7 h and it embodied the three-staged model: the scenario, the inquiry and the decision-making stages. The study was qualitative in nature. The data were collected through a questionnaire before and after the intervention. The data were analyzed using summative content analysis.

Intervention tended to deepen students’ know-how on vitamins and rational use of DS. Students’ experiences of learning nutritional issues through the SSI method were generally positive. The scenario stage was considered current and authentic. The inquiry stage and decision-making stage helped in understanding the societal connections between the study task and the rational use of DS.

SSI method enhances students’ knowledge about the rational use of DS. E-learning environment gave students possibilities to work collaboratively. Especially, possibilities to discuss with peers and share own experiences supported learning.

To solve the need of dietary supplements (DS) is a complex nutritional issue for society and for individuals. Since consumption of special diets has increased among adolescents, the rational consumption of DS is relevant and interesting learning topic at secondary school.

This article explores to what extent the long debate in England over the funding of long-term care (LTC) has involved learning from abroad.

It draws on Mossberger and Wolman’s (2003) framework which proposes criteria for assessing policy transfer as a form of prospective policy evaluation: awareness; assessment and application. The documents examined are the sources cited by the reports that examined funding LTC in England since 1999. The study uses interpretive content analysis in a deductive approach (applying the framework) that focuses on both manifest and latent content.

It finds that both the reports and the cited studies tend to focus on a fairly narrow range of nations, with most attention on Germany, Japan and Scotland. Most studies broadly do not provide much in the way of a clear rationale, and the level of details provided varies. There is relatively little focus on problems. Aims, objectives and goals are little mentioned in some studies, but they tend to be fairly abstract or “high level.” Similarly, there is limited detail on settings. Finally, only a few studies provide a clear recommendation.

It focuses on the neglected topic of the evidence behind reports which are intended to provide recommendations for policy change. The Mossberger and Wolman’s (2003) framework has been used in a small-scale but appears to be well-suited for this purpose.

Single-party regimes increasingly use Subnational Performance Assessments (SPAs) – rankings of provinces and districts – to improve governance outcomes. SPAs assemble and publicize information on local government performance to facilitate monitoring and generate competition among officials. However, the evidence are sparse on their effects in this context. The authors argue that built-in incentive structures in centralized single-party regimes distort the positive impact of SPAs.

The staggered rollout of the Vietnam Provincial Governance and Public Administration Performance Index (PAPI) created a natural experiment. Due to 2010 budget constraints, the first iteration of the PAPI survey covered only 30 of Vietnam’s 63 provinces before covering all in 2011. The PAPI team used matching procedures to identify a statistical twin for each province before randomly selecting one from each pair. The authors use randomization inference to compare the outcomes of these control and treatment groups in 2011.

Exposure to PAPI helped improve almost all aspects of governance; however, significant evidence of prioritization bias exist. The positive effects only persisted for the dimension of administrative procedures, which was the one area of governance that was prioritized by the central government at the time. Other dimensions only registered short-term effects.

Our study provides an examination of the impact of SPAs in a single-party regime context. In addition, the authors leverage the natural experiment to identify information effects causally. The authors also look past short-term effects to compare outcomes for five years after the treatment occurred.

This study aims to investigate the moderating effect of sustainability app on environmental citizenship behavior on the basis of norm-activation model.

A questionnaire survey, which comprises five variables (i.e. awareness of consequences, ascription of responsibility, personal norms, environmental citizenship behavior in a private sphere and environmental citizenship behavior in a public sphere) measured through 16 items, was conducted in the USA by using Amazon Mechanical Turk. With 549 valid respondents’ answers in hand, the collected data were analyzed applying a multi-group structural equation modelling technique with IBM SPSS AMOS 23 software program.

The results revealed that there is a positive and significant relationship between awareness of consequences, ascription of responsibility, personal norms and environmental citizenship behavior in both private and public sphere. Furthermore, this study attested that sustainability apps utilization has a moderating effect on the predictors of environmental citizenship behaviors.

Past studies have seldom examined the contribution of mobile apps to environmental sustainability. This paper enriches the extant academic literature in the field of technology for behavior change, and bears significant implications on how sustainability apps can be adopted by governments, policymakers, organizations and teacher educators to engage people and stimulate environmental citizenship behaviors.

The purpose of this paper is to bring out the possibility of selecting good leaders in Asian countries, i.e., China and Singapore.

Since comparative historical analysis enhances the objectivity for academic discussion, Deng Xiaoping’s and Lee Kuan Yew’s leadership successions have been chosen as the cases for studies by virtue of “method of agreement”. Incorporating “argument based on the contrary” into the context for macro-historical analysis, this paper characterises the duo’s successful (at least quite successful) leadership successions, thus offering an alternative paradigm beyond Western-style democracy.

Both cases of post-Mao China and the independent Singapore indicate that in quite a number of Asian countries, good leaders could still be selected beyond universal suffrage as practised among Western Electoral Democracies, mainly because of the elites-driven context. As to the duo’s succession results, Deng Xiaoping’s selection of leaders was somewhat successful, while Lee Kuan Yew’s was phenomenal.

This paper offers readers a glance over the possibility of selecting good leaders in Asian countries not fully based on Western-style democracy. Learning from the duo’s leadership successions, the West may treat elite politics as the supplement under Western Electoral Democracies in order to avoid their countries falling into the trap of populism. The West could meanwhile consider the exceptional criteria prized by the duo for leadership successions. Considering such interactions among elites in the real-life context, it could serve as an alternative model to Western-style democracy.

Supply chain (SC) professionals and their competence play a key role in creating value and competitive advantage for companies. A considerable amount of this competence is developed at work, but little is known about how this takes place. Drawing on constructivist learning theory, the authors investigate how SC professionals develop their competence at work.

The study takes off from a theoretical framework of workplace learning mechanisms, followed by a series of in-depth interviews with an expertise panel of profoundly competent and experienced SC professionals.

The results provide detailed insights into the learning process of SC professionals. The key findings show that SC professionals use a wide range of learning mechanisms throughout their careers, and that the contribution and complexity of these mechanisms differ and change dynamically with seniority. The findings also show that learning mechanisms should not be viewed as isolated phenomena, but closely related to every-day SCM work as well as learning attitude.

By conceptualizing learning as a process, and congregating the fragmented literature into a framework of workplace learning mechanisms, this research provides a theoretical reference point for future studies. The empirical findings bring a new level of detailed knowledge on how SC professionals learn at work.

The results can assist SC professionals, HR managers and academic program leaders in their quest to develop competence in the field of SCM.

This paper makes a unique contribution to the human aspects of SCM literature by presenting the first study that investigates in depth the crucial but complex process of how workplace learning takes place for SC professionals in practice.

The current study evaluated (1) characteristics of the community leadership development program associated with successful participant recruitment, (2) active ingredients that promoted fellow engagement and program completion and (3) how the program addressed blackness and racism.

Individual interviews were conducted with a representative subset of former program fellows.

Results indicated that offering training in small cohorts and matching fellows with individual mentors promoted program interest. Program strengths and unique ingredients included that the program was primarily led by people from the Black community, program malleability, and that the program was a partnership between fellows and leadership. Additionally, the program was responsive to fellows’ needs such as by adding a self-care component. Fellows also noted dedicated space and time to discuss race and racism. Results offer a unique theoretical perspective to guide leadership development away from the uniform or standardized approach and toward one that fosters diversity and equity in leadership.

Altogether, this work demonstrates how leadership development programs can be participant-informed and adapted to participants’ social and cultural needs.
