Abstract
Purpose
Binder jetting is a promising route to produce complex copper components for electronic/thermal applications. This paper aims to lay a framework for determining the effects of sintering parameters on the final microstructure of copper parts fabricated through binder jetting.
Design/methodology/approach
The knowledge gained from well-established powder metallurgy processes was leveraged to study the densification behaviour of a fine high-purity copper powder (D50 of 3.4 µm) processed via binder jetting, by performing dilatometry and microstructural characterization. The effects of sintering parameters on densification of samples obtained with a commercial water-based binder were also explored.
Findings
Sintering started at lower temperature in cold-pressed (∼680 °C) than in binder jetted parts (∼900 °C), because the strain energy introduced by powder compression reduces the sintering activation energy. Vacuum sintering promoted pore closure, resulting in greater and more uniform densification than sintering in argon, as argon pressure stabilizes the residual porosity. About 6.9% residual porosity was obtained with air sintering in the presence of graphite, promoting solid-state diffusion by copper oxide reduction.
Originality/value
This paper reports the first systematic characterization of the thermal events occurring during solid-state sintering of high-purity copper under different atmospheres. The results can be used to optimize the sintering parameters for the manufacturing of complex copper components through binder jetting.

Abstract
Purpose
The use of high-density remote storage facilities helps alleviate competing space needs in academic medical libraries while they continue to support core services and supply service copies of resources.
Methodology/approach
Four academic medical libraries in the Texas A&M University System and the University of Texas System will highlight their participation in a regional collaborative storage facility using the Resource in Common (RIC) model.
Findings
Results will show how library services and facilities changed since moving some or all of print collections to JLF.
Originality/value
The RIC model has proven to be a success in recovering user space without losing access to resources.

The purpose of this paper is to identify how employees feel about having more meetings and what can be done to improve employees' feelings about their work meetings.
Abstract
Purpose
The purpose of this paper is to identify how employees feel about having more meetings and what can be done to improve employees' feelings about their work meetings.
Design/methodology/approach
Data were obtained from three samples of working adults. The first was a convenience sample recruited by undergraduate students (n=120), the second was a stratified random sample from a metropolitan area in the southern USA (n=126), and the third was an internet‐based panel sample (n=402). Constant comparative analysis of responses to open‐ended questions was used to investigate the overarching research questions.
Findings
It is found that employees enjoy meetings when they have a clear objective, and when important relevant information is shared. Consistent with conservation of resources theory, most employees are unhappy with meetings when they reduce their work‐related resources (e.g. meetings constrain their time, lack structure and are unproductive).
Practical implications
The data suggest that meetings appear to be both resource‐draining and resource‐supplying activities in the workplace. Researchers and managers should consider overtly asking about how people feel about meetings, as a means of identifying areas for future research inquiry and targets for improvement in the workplace generally.
Originality/value
The paper describes one of the few studies on meetings that ask the participants overtly what their feelings are regarding their workplace meetings. Additionally, the paper illustrates the usefulness of qualitative data analysis as a means for further understanding workplace activities viewing respondents as informants.

Abstract
Purpose
This paper provides a five-step Enterprise Architecture Management (EAM) approach to systematically guide the development and implementation of contextualised Sales and Operations Planning (S&OP) designs.
Design/methodology/approach
A case study is conducted at a European chemical manufacturer. The research applies the five-step approach, embracing the descriptive and prescriptive EAM functions combined with the lens of contingency theory.
Findings
The research findings demonstrate the suitability of the proposed EAM approach for the contextualisation of S&OP designs from a contingency theory perspective. Its descriptive EAM function serves to assess context-specific S&OP challenges and enables to analyse the contextual fit of S&OP designs. Its prescriptive EAM function guides the development and implementation of context-specific S&OP designs towards increasing the S&OP effectiveness. EAM's integrated view onto people, process and information technology served to analyse current practices on the dynamics of S&OP contextualisation in innovation- and quality-driven contexts. Thereby, the paper contributes to a better S&OP contingency understanding.
Practical implications
The EAM approach offered in this paper provides a concrete and practically applicable guidance to support managers to face their context-specific challenges and guide the contextualisation of their S&OP designs to increase the S&OP effectiveness. Moreover, practitioners can improve their understanding regarding the need for S&OP design adjustments to reflect changes in their companies' contingencies.
Originality/value
The research introduces a novel EAM approach for S&OP contextualisation, particularly reflecting contingency theory's dynamic view of structural adjustments to regain fit (SARFIT).

Abstract
Purpose
This paper aims to offer evidence-based findings on the under-researched role of finance in the sales and operations planning (S&OP) process, aiming to guide academics and practitioners towards successful S&OP implementations.
Design/methodology/approach
The research builds upon a multiple case study, embracing five Latin American subsidiaries of four global manufacturing corporations from the consumer goods, chemical and pharmaceutical industries. Following an exploratory approach, the case study results are analysed in within- and cross-case analyses.
Findings
The research findings are synthesised into a framework, demonstrating relevant benefits from the engagement of finance along the S&OP process and the implications of its interactions with traditional S&OP functions as sales, marketing and operations. The paper shows how finance adds value in supporting the process, enabling decisions on costs, margins, capital expenditures and return on investments. Finance strengthens S&OP when assessing demand- and supply-related risks and facilitates comparing the functional business areas' plans to budget. While finance participation is highlighted as necessary for supporting successful S&OP implementations, it also receives valuable inputs in return, characterising a two-way communication role that benefits the entire organisation.
Originality/value
This is the first research paper focusing on empirically exploring the role of finance within S&OP, going beyond initial insights from practice and academia. It provides practitioners and scholars with an in-depth, evidence-based view of finance's integration along the S&OP process.

Abstract
Diversified trading networks have recently drawn a great deal of attention. In the process, the importance of diversity has perhaps been overemphasized. Using the trade in port wine from Portugal to Britain as an example, this essay attempts to show how a market once dominated by general, diversified traders was taken over by dedicated specialists whose success might almost be measured by the degree to which they rejected diversification to form a dedicated “commodity chain.” The essay suggests that this strategy was better able to handle matters of quality and the specialized knowledge that port wine required. The essay also highlights the question of power in such a chain. Endemic commodity-chain struggles are clearest in the vertical brand war that broke out in the nineteenth century, which, by concentrating power, marked the final stage in the transformation of the trade from network to vertical integration.

The purpose of this paper is to deliver an insight into the interaction effects of process‐oriented management and business intelligence (BI).
Abstract
Purpose
The purpose of this paper is to deliver an insight into the interaction effects of process‐oriented management and business intelligence (BI).
Design/methodology/approach
The paper takes up publications from the fields of BI and business process management and analyzes the state‐of‐the‐art of process‐centric business intelligence (PCBI). To highlight the potentials and limitations of the concept, two exemplary use cases are presented and discussed in depth. Furthermore, a vision for the technical implementation is sketched.
Findings
PCBI is found to play an important role in an organization's strive for competitiveness. The concept's potential benefits are significant. However, the overall levels of adoption and maturity of the concept within real‐world organizations appear to be rather low at the moment.
Research limitations/implications
The paper discusses solely two exemplary use cases – the most that could be done within the scope of a journal publication. Therefore, the explanatory power and the representativeness of the results need to be scrutinized in detail.
Practical implications
The paper highlights the practical significance of PCBI. It therefore represents a useful source of information for both practitioners and academics who are interested in improving the efficiency and effectiveness of an organization's information supply in support of its processes.
Originality/value
The paper motivates, describes, and analyzes the concept of PCBI. Furthermore, it provides examples of the concept's adoption and benefits from a practitioner's point of view.

Abstract
Purpose
The purpose of this paper is to assess the current state of performance measurement (PM) in academic literature and in the automotive supply chain (SC). The research question is to what extent PM systems (PMS) in academic literature and in industry are applicable in automotive logistics.
Design/methodology/approach
The authors use a combination of a systematic literature review (SLR) and an industry survey. The SLR is used to identify literature on design aspects for PMS and current PMS reported in academic literature. The survey adds an industry perspective and is used to validate the design aspects found in literature. The synthesis aims to deliver both, current research gaps and needs in industry.
Findings
The findings from SLR indicate, there is a broad base of literature regarding design aspects for PMS. Literature on PMS in context of automotive logistics is nevertheless rare. The industry survey leads to the conclusion that conformity with design aspects from literature increases added value of PMS. Nevertheless, current PMS show improvement needs in automotive context. Academic literature lacks detailed process orientation, transparency and is seen as too high level to be helpful for practitioners. For systems in industry, the SC perspective can be improved. In addition, applicability for continuous improvement is identified as research need in industry and literature.
Research limitations/implications
Due to the selected survey approach, additional research is required to obtain more generalizable results. To increase reliability and validity, a selection of the findings should be further analyzed, e.g. by focusing on regions outside Western Europe or a more in depth analysis of selected aspects. In addition insights into selected research topics highlighted in the paper should be assessed in detail by applying different methodologies (e.g. case studies) to validate the findings.
Originality/value
The findings add to the research on PMS. Latest academic literature is reviewed. The findings are combined with an industry perspective. The combination of SLR and a broad survey enables us to draw conclusions which are relevant for researchers and practitioners alike. Where academic research should focus more on the practical applicability, industry can benefit from the findings by integrating a more holistic perspective into their PMS, especially with a SC wide evaluation.
