Designing an economically optimal repetitive group-sampling plan based on loss functions

Acceptance sampling is a quality assurance tool, which provides a rule for the producer and the consumer to make acceptance or rejection decision about a lot. This paper attempts to develop a more efficient sampling plan, variables repetitive group sampling plan, based on the total loss to the producer and consumer. To design this model, two constraints are considered to satisfy the opposing priorities and requirements of the producer and the consumer by using Acceptable quality level (AQL) and Limiting quality level (LQL) points on operating characteristic (OC) curve. The objective function of this model is constructed based on the total expected loss. In order to illustrate the application of the proposed model, an example is presented. In addition, the effects of process parameters on the optimal solution and the total expected loss are studied by performing a sensitivity analysis. Finally, the efficiency of the proposed model is compared with the variables single sampling plan, the variables double sampling plan and the repetitive group sampling plan of Balamurali and Jun (2006) in terms of average sample number, total expected loss and its difference with ideal OC curve.

The “Absence” of Asian Regional Economic Integration and the Development Orientation of the Belt and Road

Asia has a special significance in China’s neighborhood strategy. Geographically, the Belt and Road Initiative faces the countries of Asia or China’s neighbors in the first place. Asia is clearly marked by an imbalance in and “absence” of regional economic integration. This “absence” is two-fold: it is expressed on the one hand as a lack of unified institutional arrangements for regional economic integration, and on the other as the inability of underdeveloped countries in the region to truly participate in regional economic integration and thereby gain opportunities for development. Compared with the rule-oriented nature of existing regional economic integration mechanisms, the Belt and Road Initiative, as a new type of regional cooperation mechanism, displays an orientation towards development. All existing regional economic integration arrangements, regardless of their form, establish specific rules on access thresholds, the rights and duties of member countries, schedules and roadmaps, dispute resolution mechanisms and so forth. This is not the case for the Belt and Road, which is not predicated on specific rules, but establishes its overall framework by orienting itself towards development. Overall, the development orientation of the Belt and Road is helpful not only in overcoming the inherent defects of Asian regional economic integration, but in responding to the new challenge of anti-globalization. This is an institutional public good that China offers to Asia and to the world.     

Bitch,slut, skank,cunt: patterned resistance to women’s visibility in digital publics

Resistance to women’s public voice and visibility via street harassment and workplace sexual harassment have long constrained women’s use of and comfort in physical public spaces; this gender-based resistance now extends into digital arenas. Women face extreme hostility in the form of digital sexism in discussion rooms, comment sections, gaming communities, and on social media platforms. Reflecting on two years of in-depth interviews with women who have been on the receiving end of gender-based digital abuse (n?=?38), conversations with industry professionals working in content moderation and digital safety, the extant literature, and news stories about digital attacks against women, I offer a lens to think through the prominent patterns in digital sexism, showing (1) that aggressors draw upon three overlapping strategies – intimidating, shaming, and discrediting – to limit women’s impact in digital publics, (2) the way femininity and femaleness are used to undermine women’s contributions, and (3) men call attention to women’s physicality as a way to pull gender – and the male advantage that comes with it – to the fore in digital exchanges. Finally, I argue that when digital sexism succeeds in pressing women out of digital spaces, constrains the topics they address publicly, or limits the ways they address them, we must consider the democratic costs of gender-based harassment, in addition to the personal ones.     

Public sector managers: the decision to leave or remain in a job

The public sector faces a grave problem as far as managerial retention as the result of the increasing number of retirements and of voluntary resignations. Despite the vital interest in managerial turnover in the public sector, research is scarce. This study, which increases our understanding of why public sector managers leave their positions, takes a qualitative and narrative research approach in examining voluntary turnover. Interviews were conducted with operations managers (in education, social care, and technical activities) at three Swedish municipalities. We identify a multitude of environment push and pull factors with a focus on administrative support, supervisory support and illegitimate tasks. The narratives of managerial turnover reveal the complexity of the decision to leave or remain in a job, containing a mixture of push and pull factors, negative feelings, unmet expectations and extraordinary events. Three possible HRD actions to decrease undesirable managerial turnover are identified: re-work organizational structures; re-model job characteristics; and re-examine managerial turnover decisions as a long and complex process. Our hope is that the findings are used for ultimately create healthy organizations.     

Relationship management through social media influencers: Effects of followers’ awareness of paid endorsement

This study aimed to examine the effects of awareness of paid endorsements by social media influencers on followers’ cognitive persuasion knowledge (ad recognition), attitudinal persuasion knowledge (relationships with the influencer), and behavioral intentions, specifically eWOM intention and purchase intention. Employing an online survey (N = 269), this study found that awareness of paid endorsement relates to ad recognition, which is correlated with purchase and eWOM intentions. We also found that awareness of paid endorsement is correlated with influencer-follower relationship, which is associated with purchase and eWOM intentions. However, ad recognition does not affect influencer-follower relationship. Implications for public relations theory, practice, and policy are discussed.     

Égalité entre hommes et femmes et gouvernance des chaînes d'approvisionnement mondiales: promouvoir les droits des travailleuses

La gouvernance privée telle qu'elle découle des différentes initiatives prises par les multinationales pour promouvoir le respect de normes sociales et l'égalité hommes‐femmes a eu peu d'effet sur les discriminations fondées sur le genre dans les chaînes d'approvisionnement mondiales. Les auteures soulignent l'intérêt des Principes directeurs des Nations Unies relatifs aux entreprises et aux droits de l'homme en la matière, estimant qu'il est indispensable de recourir à une gouvernance «stratifiée» associant public, privé et acteurs sociaux pour lutter contre cette discrimination et intégrer le souci de l'égalité des sexes dans l'exercice de la diligence raisonnable exigée en matière de droits de l'homme.     

Level of choice in older women’s decisions to retire or continue working and associated well-being

Retirement is a complex life transition. Women’s retirement, like their work lives, may be further complicated, for example, by family or financial obligations; they may feel forced to retire or to continue working or feel they have the choice to do so. This study examines the role of voluntary versus involuntary retirement or continued work participation among retirement-age women; specifically, the relationships between choice, work status, and well-being. Compared to women forced to retire, women who chose retirement or continuing to work had higher levels of life satisfaction. Findings highlight the importance of examining retirement within the life course context.     

超级网络平台限制交易行为的反垄断规制

从“3Q大战”“3百大战”到天猫京东“二选一”事件，超级网络平台实施限制交易行为的现象越演越烈，也成为当前互联网领域的反垄断难题。我国反垄断法律法规在对网络空间的相关市场及市场支配地位的认定上存在适用困境，超级网络平台滥用市场支配地位的行为无法被认定且无法有效规制的现象长期存在。为规范超级网络平台的经营行为，应当调整《反垄断法》关于相关市场与市场支配地位的认定规则，将反垄断案件纳入公益诉讼范围，采取国家诉讼和私人诉讼并行的双重诉讼机制，减轻原告举证责任负担，同时将《反垄断法》与《电子商务法》衔接适用。     

Optimal design of repetitive group sampling plans for Weibull and gamma distributions with applications and comparison to the Birnbaum–Saunders distribution

In this paper, we propose a multiple deferred state repetitive group sampling plan which is a new sampling plan developed by incorporating the features of both multiple deferred state sampling plan and repetitive group sampling plan, for assuring Weibull or gamma distributed mean life of the products. The quality of the product is represented by the ratio of true mean life and specified mean life of the products. Two points on the operating characteristic curve approach is used to determine the optimal parameters of the proposed plan. The plan parameters are determined by formulating an optimization problem for various combinations of producer's risk and consumer's risk for both distributions. The sensitivity analysis of the proposed plan is discussed. The implementation of the proposed plan is explained using real-life data and simulated data. The proposed plan under Weibull distribution is compared with the existing sampling plans. The average sample number (ASN) of the proposed plan and failure probability of the product are obtained under Weibull, gamma and Birnbaum–Saunders distributions for a specified value of shape parameter and compared with each other. In addition, a comparative study is made between the ASN of the proposed plan under Weibull and gamma distributions.
