Enabling children’s deliberation in deliberative systems: schools as a mediating space

In recent years, there has been a growing scholarly interest in conceptualising schools beyond their educational functions, as sites and agents of democracy. Yet this interest is often underpinned by a narrow conception of democracy, focusing solely on schools’ public and social aspects. To capture the democratic potential of schools more fully, this article suggests adopting a deliberative systems approach, which conceptualises democracy as differentiated yet linked sites of democratic communications and views schools as one such site. Using this approach as a broader framework and drawing on the fieldwork conducted in two Japanese schools, this article identifies the condition under which schools can become a meaningful part of deliberative systems. It reveals that schools contribute to deliberative systems when they serve as a bridge between children’s everyday practices and deliberative actions in the public space. In light of the findings, this article suggests conceptualising schools as a ‘mediating space’.     

Tempered Mittag-Leffler Lévy processes

In this article, we introduce tempered Mittag-Leffler Lévy processes (TMLLP). TMLLP is represented as tempered stable subordinator delayed by a gamma process. Its probability density function and Lévy density are obtained in terms of infinite series and Mittag-Leffler function, respectively. Asymptotic forms of the tails and moments are given. A step-by-step procedure of the parameters estimation and simulation of sample paths is given. We also provide main results available for Mittag-Leffler Lévy processes (MLLP) and some extensions which are not available in a collective way in a single article. Our results generalize and complement the results available on Mittag-Leffler distribution and MLLP in several directions. Further, the asymptotic forms of the moments of the first-exit times of the TMLLP are also discussed.     

Progressive censoring with fixed censoring times

In this paper, we revisit the progressive Type-I censoring scheme as it has originally been introduced by Cohen [Progressively censored samples in life testing. Technometrics. 1963;5(3):327–339]. In fact, original progressive Type-I censoring proceeds as progressive Type-II censoring but with fixed censoring times instead of failure time based censoring times. Apparently, a time truncation has been added to this censoring scheme by interpreting the final censoring time as a termination time. Therefore, not much work has been done on Cohens's original progressive censoring scheme with fixed censoring times. Thus, we discuss distributional results for this scheme and establish exact distributional results in likelihood inference for exponentially distributed lifetimes. In particular, we obtain the exact distribution of the maximum likelihood estimator (MLE). Further, the stochastic monotonicity of the MLE is verified in order to construct exact confidence intervals for both the scale parameter and the reliability.     

Monitoring S3: Key dimensions and implications

Our work analyses the implications of a smart specialisation strategy (S3) monitoring model based on a system that considers three main axes linked to the logic of the strategies: output/results, smart specialisation process, and a learning component, on which we build our main approach. This strategic learning is based on the logic that S3 presents a new paradigm within the innovation policy scope that requires the inclusion of monitoring schemes that integrate the assessment of the dynamic process under which both public administration and other innovation stakeholders learn and improve their activities (within and without the strategy) thanks to the learning gathered throughout S3 (and its instruments and projects) implementation. The article also discusses this logic within the current and the next programming period for S3, and the role monitoring has or will have, while analysing the opportunities and challenges it presents.     

信息不对称下价格随机的应急数量折扣契约研究

以市场需求和市场价格随机波动的二级供应链为研究对象,寻找其在信息不对称条件下绩效优化的路径。通过显示原理分别构建生产成本和销售成本信息不对称时应急供应链的数量折扣契约模型,得到最优订货量与最佳批发价策略。通过具体的算例加以验证,分析了信息不对称程度对供应链上成员及整个供应链绩效的影响。研究结果表明：当突发事件造成市场价格随机波动和市场需求变化时,供应链上的跟随者能从隐瞒私人信息中获利。但当市场需求增大时,整个供应链绩效受损,反之则反是。这与以往研究在市场需求随机、市场价格固定和信息不对称条件下的结论迥异。     

需求分布规律变化情况下的报童订货策略

在需求分布规律变化情况下,报童在进行订货决策时会因为错误判断需求分布规律而导致期望库存成本增加。为了解决这一问题,本文集成传统历史需求信息和非传统需求信息以正确地认知需求分布规律,在此基础上决策订货量。假设需求服从均值不同、方差相同的两种类型的正态分布,每一种正态分布的概率已知。利用信号检测理论构建基于历史需求信息与需求分布概率的报童最优订货策略,并与只基于需求分布概率的直觉规则订货策略进行对比。结果表明：只要排除需求分布概率很大或很小两种极端情况,最优订货策略比直觉规则订货策略在控制期望库存成本方面的作用更明显,即利用历史需求信息可以有效修正报童对实际需求分布的检测结果,从而提高实际订货决策的准确性。研究结果对传统历史需求信息和非传统需求信息的集成以及需求信息交换等有一定的管理学启示和应用价值。     

Psychometric properties of the “parent-child relationship inventory” (PCRI) in a portuguese forensic sample

In Portugal, there is a gap regarding psychological tests validated for forensic contexts, particularly those related to child custody issues. The Parent–Child Relationship Inventory (PCRI) is one of the most used instruments in child custody contexts. This study aimed to analyze the psychometric properties of PCRI in a Portuguese forensic sample. PCRI factorial structure and psychometric properties were analyzed in a sample of 144 parents involved in child custody assessments. The questionnaire showed good internal consistency, except for the parental support, autonomy, and role orientation scales. It also showed good discriminant capacity. The confirmatory factor analysis did not replicate the 7-factor model proposed by Gerard. The results were discussed based on the use of PCRI in the context of child custody assessment.     

Separations: A Personal Account of Bowen Family Systems Theory

This paper is a personal account of my own family of origin research. It explores the impact of separations from parents, nuclear family, and extended family through a Bowen family systems theory perspective using concepts pertaining to Bowen theory such as chronic anxiety, differentiation of self, multigenerational family process, and the emotional system. An outline of the process of doing research in ‘vivo’ with my mother as well as conversations with my supervisor are included. Theoretical differences between individual and system models are discussed. A Bowen theoretical approach to the anxiety of separations is investigated. The efficacy of engaging in family of origin work and the effects of thinking systems is examined in light of how it assisted me to view family members, family system disturbances, and clients’ emotional systems more objectively.     

Understanding Client Communities Spatially for Developing Effective Interventions: Application of Geographic Information Systems (GIS) Technology for Program Planning in Health and Human Services Agencies

Social workers are better equipped to understand the need to incorporate geographical aspects pertaining to their clients’ lives as part of their practice, given the significant influence these factors have on client well-being. Geographic Information Systems (GIS) technology is a useful tool for administrators and planners to make informed decisions regarding human service programs including examining program outcomes and impact as well as streamlining program implementation. This article synthesizes the literature to date on GIS in health and human services with examples of real world applications.     

系统工程思想视角下三产融合振兴民族村落的路径——基于贵州批林村的经验探索

农村三产融合是一个由多种要素组成的系统工程。研究基于对贵州花溪区批林村的田野调查,发现：目前批林村对三产融合进行探索的电农融合、工农融合和文旅融合项目在实施过程中存在一些阻碍,具体包括发展资金较为匮乏,基础设施难以建设;技术渗透能力不强,新型产业难以发展;村落建设人才短缺,项目规划难以推进;三产融合程度较浅,产业增值难以实现;利益联结机制欠缺,农民利益难以保障等。针对批林村现实存在的典型问题,基于系统工程思想的指导,研究为三产融合振兴民族村落构建出以下发展路径：一是完善系统顶层设计,统筹三产融合发展思路;二是精准定位发展要素,抓住三产融合关键环节;三是合理布局结构关系,优化三产融合整体功能;四是创新融合发展方式,实现三产融合系统升级;五是加强后续保障机制,促进三产融合稳步运营。
