Abstract
Purpose
The purpose of this paper is to explore how differently aggregated order data may affect inventories and service levels in a serial supply chain and compares the results against various levels of information sharing. By performing sensitivity analysis, critical parameters are identified and conjectures for explaining the divergent results on the value of information sharing in prior literature are given.
Design/methodology/approach
By using discrete event simulation, the paper analyses various approaches of differently aggregated order data compared to shared demand information.
Findings
The experiments show that suppliers cannot accurately estimate demand means and variances because of time‐depending order quantities and biasing effects of order inter‐arrival times. This may lead to inappropriate computations of reorder points and safety stocks. The aggregation of order data can improve the calculations resulting in lower inventories with almost identical service levels. The mean inventory can also be reduced by sharing information but may lead to considerably lower service levels.
Research limitations/implications
As discovered in this paper, simplifications in the supply chain structure may have large effects on the experimental results. Therefore, the value of information sharing and order aggregation strategies should be analyzed in a more complex supply chain network.
Practical implications
Some ordering mechanisms have the effect of increasing the demand variance for upstream companies. This amplification may lead to inefficiencies throughout the entire supply chain. The paper proposes solutions to managers on how they can benefit from order data aggregation and information sharing. The per period variances may be reduced leading to smaller safety stocks and lower costs for the entire supply chain.
Originality/value
The paper shows that the performance of a supply chain may be improved by aggregating order data and compares the results with improvements derived from information sharing strategies.

Abstract
Both the ideals of the European Union (EU) and the EU's recent political difficulties have attracted comparison with the Habsburg empire. In recent years, some of those making comparison have turned to the Austrian Jewish novelists, Stefan Zweig and Joseph Roth, who were crucial to the imaginative emergence of the Habsburg Myth. This paper analyses their writings and those of Robert Musil and Gregor von Rezzori in relation to the Habsburg Myth as a story about European unity, about Austria-Hungary as a supranational polity and about Austria-Hungary's self-proclaimed providential purpose in European affairs. It explores the dissonance between the Habsburg Myth and the EU's territorial composition and argues that the Habsburg Myth is, nonetheless, revealing about the EU's internal hierarchies and its geopolitical difficulties in relation to Russia.

Abstract
Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Abstract
Purpose
Non-technical skills are of increasing importance for safety engineers to perform their job. In their position as expert consultants, they work closely with managers. Thus, gaining management support is oftentimes crucial for safety engineers to successfully improve occupational health and safety. Drawing on organizational support theory (OST), this study investigates how safety engineers’ non-technical skills in communication and persuasion (i.e. rational and hard influence tactics) are related with their management support, and how management support is related with their individual task proficiency (ITP). The purpose of this paper is to examine the moderating role of safety engineers’ expert power in this context.
Design/methodology/approach
Using an online questionnaire, survey data were collected from 251 safety engineers working in Austria.
Findings
Rational influence tactics are positively related to ITP via management support, whereas hard influence tactics are not. Safety engineers’ expert power moderates the relationship between influence tactics and management support and, consequently ITP. High (vs low) expert status strengthens the positive relationship of rational influence tactics on ITP via management support. For hard influence tactics, high (vs low) expert power buffered the negative relationship of upward appeal and pressure on ITP via management support.
Practical implications
Safety engineers should rely on rational persuasion when cooperating with management to obtain support and improve their own performance.
Originality/value
This study connects the effect of influence tactics in the context of safety engineers’ work performance with OST. It demonstrates that safety engineers’ influence tactics are related to work role performance through management support and that these relationships are moderated by expert power.

Abstract
Currently, our understandings of the dynamics behind the effects of politicization on values and on administrative decision-making remain largely muddled and far from complete. The richness of theoretical accounts, amassed over the past eight decades, has yielded only a limited number of empirical examinations. This failure to develop a coherent collection of empirical works can be for the most part attributed to the complexity associated with studying values, particularly to the lack of clear and testable theories and models. This article attempts to address this deficit and to add to our understandings of the association between values and administrative decision-making at the individual level by explicitly testing the Broker-Purist (BP) model (within a sample of public procurement specialists). It is found that the BP model fits the data well, which suggest the framework as a valid and useful perspective for conceptualizing the effects of environmental politicization on administrative decision-making in public procurement specifically, and in public administration in general.

Abstract
This chapter emphasizes the interconnectedness of legal frameworks, socio-cultural norms, and policy interventions in forging a more inclusive and just society for girls and women. Despite substantial strides, gender disparities still persist across the Western world, highlighting the need for targeted actions. The chapter explores the “glass ceiling” phenomenon, the wage gap, gender-based violence, emphasizing their persistence, and the imperative of transformative policies. Shifting focus to the East, the narrative navigates through distinct trajectories of women’s rights advocacy. Religious beliefs have historically reinforced gender inequality in some Eastern societies, shaping cultural norms and limiting women’s public participation. In the context of Islam, varying interpretations have led to differing perspectives on gender roles. The chapter showcases instances of progress, such as Saudi Arabian women gaining voting rights, while acknowledging enduring challenges like female genital mutilation and forced marriages. In the conclusion part, the chapter highlights the need for sustained efforts to dismantle barriers and elevate women’s voices, fostering a global landscape marked by gender equality and women’s empowerment.

Abstract
Purpose
The purpose of this paper is to assess the prestige of the Doctor of Ministry (DMin) among Roman Catholics in leadership positions, who may be a potential market for this degree.
Design/methodology/approach
In a mail survey employing a comparative rating scale, respondents rated the prestige of the DMin relative to six other doctorates: PhD, EdD, PsyD, DBA, MD, and JD.
Findings
Ratings were provided by 184 priests, 73 deacons, and 95 directors of religious education (69 lay, 26 sisters). The DMin carried the least prestige with priests and the most with religious educators, particularly the sisters. In all groups, the DMin fared best on prestige when compared to the professional doctorates (DBA, EdD, PsyD) and worst relative to the traditional degrees (MD, JD, and PhD). When submitted to a cluster analysis, three groups emerged, corresponding to negative (46 percent), neutral (38 percent), and positive (16 percent) impressions of the prestige of the DMin. The majority of the priests (44 percent) were in the negative cluster whereas the largest proportion of deacons (45 percent) and most lay religious educators (71 percent) fell into the neutral cluster. In contrast, the largest proportion of the religious educators who were sisters by background went into the positive cluster (40 percent). With the exception of the sisters, the percentage of each group falling into the positive cluster was quite small and approximately the same size across the remaining three groups (16 percent, 15 percent, and 13 percent). A discriminant analysis of the clusters identified two discriminating functions; the primary function involved perceptions of the DMin relative to the traditional degrees (MD, JD, and PhD), whereas the very minor second function involved how the DMin is perceived in comparison to the newer practice doctorates (EdD, DBA, and PsyD).
Research limitations/implications
The response rate was low.
Practical implications
Currently, owing to its low prestige, the DMin probably does not have a sizable potential market among Roman Catholic priests, but it may appeal more to religious educators.
Social implications
The DMin may be subject to the same concerns and prejudices as raised about other professional doctorates.
Originality/value
Roman Catholics are a non‐traditional audience for the DMin. This degree's perceived prestige was not previously studied in this emerging market.
