Integrated approach for optimizing quality control in international manufacturing networks

Abstract

This article aims at providing an integrated approach for optimizing quality control in International Manufacturing Networks (IMN) which can be characterized by consisting of numerous plants acting autonomously according to an individual target system. A key challenge is to ensure the overall process quality despite distributed value creation processes and differing target systems in dynamic environments. Hence, the developed approach allows for identifying potentials in the quality control strategy using a value stream-based method to visualize quality characteristics and procedures in the production process chain. Furthermore, the approach contains a framework for identifying possible improvement measures and a simulation-based evaluation concept to evaluate the effects of different measures with respect to individual target systems. The simulation combines elements of a discrete-event simulation in order to depict the value stream with agent-based modelling for realizing different target systems by considering distinctive plant roles. The article concludes with a case study of a globally operating automotive supplier to apply the approach. A forward research agenda is proposed that evaluates the approach in multiple cases, deriving patters across companies or industries.     

Toolkits for Equity: An Antiracist Framework for Scholarly Publishing

Abstract

Fueled by a recent groundswell of support, scholarly publishing organizations are formalizing their focus on equity and inclusion, yet there is still a lack of effective programs and solutions actually in place. A cross-organizational working group is developing antiracism toolkits (for organizations, for allies, and for Black, Indigenous, and People of Color) to transform scholarly publishing workplaces and organizational cultures. The resources, which will be hosted at c4disc.org, provide a common framework for analysis, a shared vocabulary, best practices, and training materials to guide individuals and organizations as they address systemic inequities specific to the scholarly publishing community. Originally planned as a presentation at the NC Serials Conference in March 2020, this article introduces the toolkits and explains why an antiracist framework is essential to transforming scholarly publishing.     

Leadership and Effectiveness in the Context of Gender: The Role of Leaders' Verbal Behaviour*

This field study focuses on verbal consideration, which is a leadership behaviour that expresses esteem for the follower and her or his work, knowledge and opinion. It was assumed that the relationship between verbal consideration and various outcomes is moderated by the leader's gender. One‐hundred‐and‐forty leaders and 455 of their direct followers were surveyed in a one‐wave questionnaire study in Germany. Male and female leaders showed the same degree of verbal consideration as rated by their followers. Verbal consideration is related to three out of four outcome variables for both sexes. One unexpected moderating effect of leaders' gender was found: followers of male leaders displaying verbal consideration report less ‘irritation’ (a state of exhaustion considered a threat to good task fulfilment). One explanation may be that male leaders get ‘extra credit’ for showing verbal consideration as it may be thought to entail special effort, whereas for female leaders it may be seen as normal and routine. This assumption should be examined in further studies in order to get more information about the different mechanisms by which female and male leaders reach the same quality of outcomes.     

Vereinsmanagement in Zeiten der Veränderung

Associations and unions are under high optimisation pressure because of fewer public money and general changes in society. Many try to cope with this hard situation by looking for business management instruments. Quick solutions are however not easy to get. These organisations are for their members, to a high degree, social communities as well as political action communities and economic or services communities. These three different forms of communities constitute subsystems in associations with their own very specific organisatinal logic. If one of those subsystems get out of balance it would affect the two others. Modern management instruments are useless in changes projects handling changes, as long as the managing committee doesn’t initiate broad and extensive internal discussions about the future direction of the association. Project handling changes have only a chance to succeed, if they equally take into consideration all three subsystems.     

Women behaving badly: negative posts on Facebook memorial pages

This study explores negative posts in Facebook pages dedicated to dead subjects. As with places for mourning in offline environments, memorial pages in Facebook appear to exude a sacred character as objects to both celebrate the life of the deceased and grieve their departure with others. Through a two-step content analysis of an initial sample of 600 pages containing the ‘R.I.P.’ acronym in their title, we found, however, a number of posts violating conventional expectations of respect for these mourning spaces. Negative posts in memorial pages take the form of flames (i.e., insults directed at the subject of the page, its administrator, or other visitors), venting (e.g., violent language against the victimizers of the subject of a memorial page), or ‘spam’ (i.e., advertisement and content not related to the subject and purpose of the page). Moreover, while results show that most memorial pages in Facebook are created and maintained by women (even thought the subject in the majority of those pages are young males who died an untimely death), they also reveal that women post the majority of negative posts in those pages as well. In other words, whereas women seem to perpetuate traditional offline roles in connection to mourning and grieving rituals, in the online world, they are also the first ones challenging the socially sanctioned sacral attributes of those practices in social networking sites.     

A semi-Markov multistate model for estimation of the mean quality-adjusted survival for non-progressive processes

We discuss the estimation of the expected value of the quality-adjusted survival, based on multistate models. We generalize an earlier work, considering the sojourn times in health states are not identically distributed, for a given vector of covariates. Approaches based on semiparametric and parametric (exponential and Weibull distributions) methodologies are considered. A simulation study is conducted to evaluate the performance of the proposed estimator and the jackknife resampling method is used to estimate the variance of such estimator. An application to a real data set is also included.     

The City Park as a Public Good Reference for Internet Policy Making

Extensive literature has provided evidence of the organic nature of the Internet as a domain for different sorts of activities. Most policy making regarding the Internet, however, has focused on its economic dimensions (e.g. e-commerce, copyrights, privacy) while taking timid steps when it comes to its cultural and social dimensions. We propose a more comprehensive approach for global policy making on the Internet by looking retrospectively at processes that led to the creation of urban parks, and examining those processes in light of public goods theory. We conducted historical and theoretical analyses to show that, in the same way urban parks define spaces that mediate between different functions of the city, it is possible to define buffer spaces within the Internet that mediate between competing spheres of activity. As a complex phenomenon involving infrastructure, applications, and content, the Internet possesses features that can be located at different points between purely private and purely public goods. This fact parallels the growing attention that public goods theorists are paying to non-economic factors to explain the provisions of goods under circumstances that do not easily fit supply/demand laws. We argue that urban parks, as hybrid public goods, offer a reference for the design of policies that harmonize competing interests because they are spaces justified by manifold rationales (economic, political, social and cultural). As parks offer possibilities for spontaneous re-appropriations of the city as a cohesive entity (i.e. something beyond a disconnected collection of populations), defining similar multi-purpose spaces on the Internet would facilitate coexistence of competing and complementary behaviours by allowing users to re-appropriate this technology as a comprehensive entity beyond a mere aggregation of transactions and interests.     

Linking Maternal Warmth and Responsiveness to Children's Self‐regulation

The present study demonstrated that a more differentiated view of positive parenting practices is necessary in the study of children's acquisition of self‐regulation. Here, the unique contributions of maternal warmth and responsiveness to distress to children's self‐regulation were tested in a sample of 102 German mothers and their kindergarten children (51 girls and 51 boys). Behavior regulation and internalization of rules of conduct were examined as specific components of children's self‐regulation. As expected, maternal warmth was positively related to the child's behavior regulation. Responsiveness to distress was positively linked to the child's internalization of rules of conduct. No significant interactions between maternal parenting and either the child's gender or effortful control were found. The results are discussed with regard to the unique functions that different parenting practices have for children's self‐regulation.     

LABOR MARKET PERFORMANCE EFFECTS OF DISCRIMINATION AND LOSS OF SKILL

We examine the impact of discrimination on labor market performance when workers are subject to a risk of losing skills during an unemployment experience. Within a search and matching framework, we show that both natives and immigrants are affected by discrimination. Discrimination in one sector has positive spillovers, inducing employment to increase in the other sector and the effect on labor market performance therefore depends on whether discrimination is present in only one sector or in both. Discrimination may induce workers to train more or less than natives after having lost their skills, dependent upon in which sector there is discrimination. Net output tends to be most negatively affected by discrimination among high‐skilled workers. (JEL J15, J31, J61, J64, J71)
