An M/G/1 clearing queueing system with setup time and multiple vacations for an unreliable server

This paper studies an M/G/1 clearing queueing system with setup time and multiple vacations, in which all present customers in the system are served simultaneously and breakdowns may occur in busy or setup period. We investigate the stationary distribution of system size and the Laplace–Stieltjes transform of sojourn time. In addition, various performance measures are discussed, such as the mean system size at arbitrary time and the mean length of a vacation circle. Moreover, a cost analysis is carried out for this queueing system. Numerical results are presented to study the sensitivity of the system parameters on the expected cost function and system performances.     

流程、合规与操作风险管理

商业银行风险管理研究中“违规活动—操作风险—信用风险”风险链条尚未得到足够重视． 巴塞尔委员会全面风险管理框架下的众多风险是分层次的，最底层是合规与操作风险，合规与操作风险做到位能极大降低其他风险发生的概率． 以往由于缺少数据支撑，信用风险的合规与操作风险动因无法建立，本文基于“流程—节点—风险点—控制措施—违规事件”关联模型，建立了合规与操作风险的动因库和损失数据库，并在理论上对风险链条上的风险传递关系进行初步探索． 首先基于流程对合规与操作风险动因进行解析，寻找深层次的人员违规和操作风险动因; 其次，探讨了金融机构如何通过业务流程再造改善合规与操作风险管理; 最后是基于流程的操作风险量化建模． 基于实践，总结提炼了“三位一体”的金融机构合规与操作风险管理模式，包含理论基础、信息系统和保障机制，该模式在诸多金融机构中得到运用，并取得显著成效．     

Assessing Politicized Sexual Orientation Identity: Validating the Queer Consciousness Scale

Building on psychological theories of motivation for collective action, we introduce a new individual difference measure of queer consciousness, defined as a politicized collective identity around sexual orientation. The Queer Consciousness Scale (QCS) consists of 12 items measuring five aspects of a politicized queer identity: sense of common fate, power discontent, system blame, collective orientation, and cognitive centrality. In four samples of adult women and men of varied sexual orientations, the QCS showed good test-retest and Cronbach’s reliability and excellent known-groups and predictive validity. Specifically, the QCS was positively correlated with identification as a member of the LGBTQ community, political liberalism, personal political salience, and LGBTQ activism and negatively correlated with right-wing authoritarianism and social dominance orientation. QCS mediated relationships between several individual difference variables and gay rights activism and can be used with both LGBTQ people and allies.     

Shared service center research: A review of the past,present, and future

More than 75% of Fortune 500 companies have established models of shared services with the aim of gaining superior performance by cost savings and service enhancements. Despite scholars' complaints about scant shared service center (SSC) research, this study shows that the actual shortcoming in this stream concerns a high fragmentation of the academic literature (e.g., we found 137 works in the initial search and 83 works in a refined screen). In this first comprehensive literature review, we synthesize peer-reviewed articles and classify them into 4 perspectives according to their research questions (i.e., determinant, process, control, and outcome). We identify 17 major research areas across these perspectives. Additionally, we provide information on methodologies and theories. On the basis of the literature synthesis, we discuss opportunities and gaps and propose an agenda for future research. Specifically, we suggest 3 potential research directions (i.e., direct relationships, mediating, and outcome effects) regarding SSCs during their operational maturity phase.     

Women’s experiences of,and attitudes to,maternity education across the perinatal period in Victoria,Australia: A mixed-methods approach

Background

While the provision of maternity education across the perinatal period can increase the confidence and self-efficacy in childbearing women, there is still thought to be a lack of effective educational resources for parenthood. This study, conducted in Victoria, Australia, investigated women’s experiences of, and attitudes to education communicated in maternity service provision.

Videoing Supervision: Messages for Probation Practice

This paper reports on a PhD study, investigating the supervision of women service users (WSUs), by probation officers (POs) based on video data of one-to-one supervision sessions. The research identifies competing agendas of probation in England and Wales – one side emphasises punishment, whilst the other encourages humanistic, relationship-based practices. POs, routinely juggling these opposing expectations, appreciate traditional probation values of giving the WSU a voice and embracing psychodynamic approaches, to provide structure and support in confronting the complexities of officer/service user interactions. However, the data show that driven by managerialist enforcement requirements, it is the punitive discourse which is more frequently translated into practice. Organisational pressures, feelings about the person opposite, the offence or the individual’s background can manifest as conscious or unconscious micro-messages or masking messages. Just as SUs put on masks to disguise negative emotions or feel powerful, so too do POs; POs recognise masks and deceptions in SUs and, similarly, SUs are aware of this dynamic with POs. The research identifies practitioner ambivalence to certain narratives, particularly sexual abuse or poor mental health and, it is argued, reflective supervision is needed to deconstruct difficult personal and professional issues.     

老字号品牌价值共创机理及对策研究——基于服务主导逻辑视角

将服务主导逻辑的思维范式引入老字号企业中来,结合消费文化和社会情景价值理论探讨该领域中品牌价值的共创机理,基于理论假设构建研究框架。以北京、上海、福建三个地区的不同行业老字号品牌企业为实证研究对象,对企业员工和消费者进行访谈和问卷调查。通过修正的初始量表,基于PLS-SEM方法对收集的309份有效问卷调查数据应用SPSS22.0和Smart PLS2.0进行分析,验证消费者情感价值共创的中介作用及互联网媒介交互的调节作用。分析结果表明,消费者与老字号企业共同创造价值,历史悠久的老字号品牌企业关注基于互联网媒介下不同利益相关者的互动和协同才能创造品牌价值共创的最理想点,最后为老字号品牌管理提供有益的建议和应对策略。     

湖南省学前教育普及现状调查与对策建议

湖南省实施发展学前教育三年行动计划效果明显，学前教育机构总数、在园幼儿数、学前三年毛入学率显著增加。与经济发达省份对比，湖南省学前教育普及水平还比较落后，城镇学前教育普及水平明显高于农村地区，县域之间学前教育普及水平差距明显。湖南省普及学前教育面临的主要问题是：政府主导作用发挥不够、农村学前教育普及水平落后、学前教育基础建设不足、普及学前教育路径不畅。推进湖南学前教育持续普及，需要构建学前教育公共服务体系，大力扶持农村学前教育，建立学前教育的保障体系，优化学前教育普及模式。     

国家治理体系与政府购买公共服务

政府购买公共服务关系到政府职能的转变和政府治理水平的提升,关系到政府与市场之间功能与地位的调整与理顺,因而是国家治理体系的重要一环。政府购买公共服务背后体现的是国家治理体系现代化的取向,那么在理论逻辑上是要以新公共管理理论、政府治理、第三方治理和多中心治理理论为理论基石。目前,我国政府购买公共服务还存在着范围不清、关系不顺、法律不健全的制度现实,因而必须构建科学规范的现代化的政府购买服务制度和配套制度体系,以进一步推进国家治理体系的制度现代化。
