Abstract
Purpose
The purpose of this paper is to elaborate a multi‐criteria methodology for the performance assessment of energy supply technologies, which also takes into account the dynamics of technological change.
Design/methodology/approach
The approach chosen is based on the multi‐criteria outranking methodology Preference Ranking Organisation METHod for Enrichment Evaluations (PROMETHEE), which is linked to the concept of technology's life cycle by assigning criteria weights depending on the actual development phase of a certain technology. The modifications to the PROMETHEE algorithm are described and the modified methodology is demonstrated by evaluating heat and power supply alternatives for a municipal area in Germany.
Findings
The methodology is suitable for the evaluation of energy technologies taking into account varying preferences depending on their stage of maturity. It is a feasible alternative to other methodologies which allow for interconnections like the analytic network process. The results show that, based on a multi‐criteria life cycle approach, renewable energy technologies are competitive with conventional alternatives for supplying heat and power.
Practical implications
Appropriate methods are required to elicit life cycle‐dependent preferences. Decision support should help decision makers (DMs) to articulate preferences according to different development phases and illustrate the results in the most meaningful way.
Originality/value
The methodology provides the basis for a comprehensive analysis of energy technologies at different life cycle stages. It can be used to support decision making in different situations and by various actors.

Abstract
Purpose
The purpose of this study is to describe the creation, implementation, activities and rationale for the Area Technology Centers (ATCs), an innovation adopted by the Chicago Police Department’s (CPD’s) Bureau of Detectives (BoD) in 2019 for the purpose of supporting investigations of crimes of serious violence by deploying specialized teams of officers to gather and process video and digital evidence.
Design/methodology/approach
This case study utilizes historical information and descriptive data generated by a record-keeping system adopted by the ATCs.
Findings
The ATCs were developed as a collaboration between the CPD and the University of Chicago Crime Lab (a research center). The start-up was funded by a gift from the Griffin Foundation. Detectives have made extensive use of the services provided by the ATCs from the beginning, with the result that homicide and shooting investigations now have access to more video and digital evidence that has been processed by state-of-the-art equipment. The CPD has assumed budget responsibility for the ATCs, which is an indication of their success. The ATC teams have been assembled by voluntary transfers by sworn officers, together with an embedded analyst from the University of Chicago.
Practical implications
The ATC model could be adopted by other large police departments. The study finds that ATCs can be effectively staffed by redeploying and training existing staff and that their operation does not require a budget increase.
Social implications
By arguably making police investigations of shooting cases more efficient, the ATCs have the potential to increase the clearance rate and thereby prevent future gun violence.
Originality/value
The ATCs are a novel response to the challenges of securing and making good use of video and digital evidence in police investigations.

Abstract
Purpose
There is no doubt about the economic importance of small‐ and medium‐sized enterprises (SMEs) in industrialised countries. The amount of research on organisational size as a factor of radio frequency identification (RFID) adoption, however, is as yet, minimal. This paper aims to fill that gap by first determining firm‐size specific characteristics of RFID and then using organisational inertia theory to derive the hypothesis that the size and structure of SMEs can be advantageous for the adoption of RFID.
Design/methodology/approach
This paper is based on organisational inertia theory and survey data.
Findings
A survey conducted among German enterprises already deploying RFID is used to test our hypothesis. It confirms that smaller enterprise size can make RFID adoption and exploitation of the productivity potential easier. Accordingly, it recommends that SMEs avoid adopting a wait‐and‐see position or restricting themselves to easy‐to‐conduct RFID automation applications.
Originality/value
The study provides a starting point for future research and facilitates knowledge accumulation and creation concerning the role of organisational size for RFID adoption.

Abstract
This chapter aims to gain a deeper understanding of the phenomenon of an ultraconservative group’s crisis communication. It delves into the communication strategies and narratives of the Taliban as they interact with the international media, particularly in relation to the women residing in Afghanistan. A qualitative content analysis of the Taliban’s initial press conference, subsequent interviews and statements on the women in Afghanistan after the Kabul takeover in August 2021 was conducted to understand how the group constructed its narrative on women. The findings suggest that the Taliban adopt a coherent communication strategy. Overall, the group seems to construct a positive image of free women in Afghanistan under their governance by representing image repair strategies of denying disadvantages and positioning themselves as supportive of women’s rights, embedded in hero narratives. Through an analysis of the data employed in this research, it transpired that the Taliban lay a special emphasis on a promising future for their home country through the implementation of the principles of human rights, with a special focus on their commitment to women’s rights and the respect they accord to women. With regard to the imposition of restrictions on Afghan women, the group can be seen to adopt an image repair strategy, employed by evading responsibility, coupled with a narrative of blaming foreign forces.

Abstract
Reports that major advances have been achieved on computational simulations of multidimensional fluid flow, heat and mass transfer during the last 20 years. Focuses on the numerical prediction of fluid flow, combustion and gas radiation in a combustion chamber of a typical industrial glass‐melting furnace. Carries out the flow simulation in a three‐dimensional calculation domain by using computer models in conjunction with the standard k ‐ ε turbulence model. Tests the predictions of spectral intensity by solving the equation of radiative transfer. Employs the Goody statistical narrow band model with the Curtis‐Godson approximation to calculate radiative properties for inhomogeneous gas mixtures.

Abstract
Purpose
The purpose of this paper is to describe the design and implementation of policies, digital infrastructures and hands-on support for eResearch at the University of Göttingen. Core elements of this activity are to provide support for research data management to researchers of all disciplines and to coordinate on-campus activities. These activities are actively aligned with disciplinary, national and international policies and e-infrastructures.
Design/methodology/approach
The process of setting up and implementing an institutional data policy and its necessary communications and workflows are described and analysed. A first assessment of service development and uptake is provided in the area of embedded research data support.
Findings
A coordination unit for eResearch brings together knowledge about methods and tools that are otherwise scattered across disciplinary units. This provides a framework for policy implementation and improves the quality of institutional research environments.
Practical implications
The study provides information about an institutional implementation strategy for infrastructure and services related to research data. The lessons learned allow insights into current challenges and work ahead.
Originality/value
With a cross-cutting, “horizontal” approach, in the Göttingen eResearch Alliance, two research-orientated infrastructure providers, a library and an IT service, combine their services and expertise to develop an eResearch service and support portfolio for the Göttingen Campus.

Abstract
Computer corpus linguistics (CCL) is a scientific innovation that has facilitated the creation and analysis of large corpora in a systematic way by means of computer technology since the 1950s. This article provides an account of the CCL pioneers in general but particularly of those in Germany, the Netherlands, Sweden, and Switzerland. It is found that Germany and Sweden, due to more advantageous financing and weaker communities of generativists, had a faster adoption of CCL than the other two countries. A particular late adopter among the four was Switzerland, which did not take up CCL until foreign professors had been recruited.

Abstract
Retailers increasingly experiment with a wide variety of store elements; this chapter focuses on in-store marketing tactics and reports the results of 12 in-store experiments conducted in cooperation with different retail chains. Experiments 1–3 address in-store signage (digital, floor) and reveal that digital screens and signage can draw customers toward merchandise and deeper into shopping aisles. Experiments 4–6 explore the impact of the organization of a display (vertical, horizontal, diagonal, waterfall) and generally demonstrate the superiority of vertical organizations of merchandise. In Experiments 7–9, results pertaining to the location of a product in a store highlight the importance of placing merchandise at eye level. With Experiments 10 and 11, the authors reinforce the importance of retail atmospherics (scent, lighting). Finally, Experiment 12 explores product placement and other factors that can enhance the effectiveness of in-store merchandise demonstrations.
