The Ideal

AbstractLetGbe a compactp-adic analytic group. We recall the well-understood finite radical{\Delta^{+}}and FC-centre Δ, and introduce ap-adic analogue of Roseblade’s subgroup{\mathrm{nio}(G)}, the unique largest orbitally sound open normal subgroup ofG. Further, whenGis nilpotent-by-finite, we introduce the finite-by-(nilpotentp-valuable) radical{\mathbf{FN}_{p}(G)}, an open characteristic subgroup ofGcontained in{\mathrm{nio}(G)}. By relating the already well-known theory of isolators with Lazard’s notion ofp-saturations, we introduce the isolated lower central (resp. isolated derived) series of a nilpotent (resp. soluble)p-valuable group, and use this to study the conjugation action of{\mathrm{nio}(G)}on{\mathbf{FN}_{p}(G)}. We emerge with a structure theorem forG,1\leq\Delta^{+}\leq\Delta\leq\mathbf{FN}_{p}(G)\leq\mathrm{nio}(G)\leq G,in which the various quotients of this series of groups are well understood. This sheds light on the ideal structure of the Iwasawa algebras (i.e. the completed group ringskG) of such groups, and will be used in future work to study the prime ideals of these rings.

Purpose The purpose of this paper is to explore insights methodology and technology by using behavioral to create a mind-set change in the way people work, especially in the age of artificial intelligence (AI). Design/methodology/approach The approach is to examine how AI is driving workplace change, introduce the idea that most organizations have untapped analytics, add the idea of what we know future work will look like and look at how greater, data-driven human behavioral insights will help prepare future human-to-human work and inform people’s work with and alongside AI. Findings Human (behavioral) intelligence will be an increasingly crucial part of behaviorally smart organizations, from hiring to placement to adaptation to team building, compliance and more. These human capability insights will, among other things, better prepare people and organizations for changing work roles, including working with and alongside AI and similar tech innovation. Research limitations/implications No doubt researchers across the private, public and nonprofit sectors will want to further study the nexus of human capability, behavioral insights technology and AI, but it is clear that such work is already underway and can prove even more valuable if adopted on a broader, deeper level. Practical implications Much “people data” inside organizations is currently not being harvested. Validated, scalable processes exist to mine that data and leverage it to help organizations of all types and sizes be ready for the future, particularly in regard to the marriage of human capability and AI. Social implications In terms of human capability and AI, individuals, teams, organizations, customers and other stakeholders will all benefit. The investment of time and other resources is minimal, but must include C-suite buy in. Originality/value Much exists on the softer aspects of the marriage of human capability and AI and other workplace advancements. What has been lacking – until now – is a 1) practical, 2) validated and 3) scalable behavioral insights tech form that quantifiably informs how people and AI will work in the future, especially side by side.

The Impact

Purpose The purpose of this paper is to describe an intervention with a group of homeless men from the Horn of Africa, service users of the Horn of Africa Health and Wellbeing Project in London. The group was conceived by the second author who noted the presence of significant psychosocial issues for her clients, but equally their reluctance to access mainstream mental health or social care services. Design/methodology/approach Designing the group and introducing it to the men involved threw up some challenges which are explored, and the impact of the group on participants is evaluated. Findings Overall both the participants and the facilitators evaluated the group positively and it appeared to have led to lasting change for some of the group members, and this is described. The authors argue that this sort of group may be a more acceptable way to work on psychosocial issues than something more directly focused on mental health intervention. The group protocol is outlined along with suggestions for future work in this area. Originality/value This intervention represents a creative alternative to more mainstream psychological interventions for homeless or exiled men.

Purpose – The purpose of this paper is to examine mechanical and metallurgical properties of AlTiN- and TiN-coates high-speed steel (HSS) materials in detail. Design/methodology/approach – In this study, HSS steel parts have been processed through machining and have been coated with AlTiN and TiN on physical vapour deposition workbench at approximately 6,500°C for 4 hours. Tensile strength, fatigue strength, hardness tests for AlTiN- and TiN-coated HSS samples have been performed; moreover, energy dispersive X-ray spectroscopy and X-ray diffraction analysis and microstructure analysis have been made by scanning electron microscopy. The obtained results have been compared with uncoated HSS components. Findings – It was found that tensile strength of TiAlN- and TiN-coated HSS parts is higher than that of uncoated HSS parts. Highest tensile strength has been obtained from TiN-coated HSS parts. Number of cycles for failure of TiAlN- and TiN-coated HSS parts is higher than that for HSS parts. Particularly TiN-coated HSS parts have the most valuable fatigue results. However, surface roughness of fatigue samples may cause notch effect. For this reason, surface roughness of coated HSS parts is compared with that of uncoated ones. While the average surface roughness (Ra) of the uncoated samples was in the range of 0.40 μm, that of the AlTiN- and TiN-coated samples was in the range of 0.60 and 0.80 μm, respectively. Research limitations/implications – It would be interesting to search different coatings for cutting tools. It could be the good idea for future work to concentrate on wear properties of tool materials. Practical implications – The detailed mechanical and metallurgical results can be used to assess the AlTiN and TiN coating applications in HSS materials. Originality/value – This paper provides information on mechanical and metallurgical behaviour of AlTiN- and TiN-coated HSS materials and offers practical help for researchers and scientists working in the coating area.

Purpose The purpose of this paper is to advance the dialogue between the disaster risk reduction (DRR) and adaptation community by investigating their differences, similarities and potential synergies. The paper examines how DRR and adaptation can inform development to tackle the underlying drivers of disaster risk. Design/methodology/approach Based on a risk-based approach to the management of climate variability and change, the paper draws from a critical review of the literature on DRR and adaptation. The study finds that known and emerging risk from disasters continues to increase dramatically in many parts of the world, and that climate change is a key driver behind it. The authors also find that underlying causes of social vulnerability are still not adequately addressed in policy or practice. Linking DRR and adaptation is also complicated by different purposes and perspectives, fragmented knowledge, institutions and policy and poor stakeholder coordination. Findings The author’s analysis suggests that future work in DRR and adaptation should put a much greater emphasis on reducing vulnerability to environmental hazards, if there is truly a desire to tackle the underlying drivers of disaster and climate risks. Originality/value This will require coherent political action on DRR and adaptation aimed at addressing faulty development processes that are the main causes of growing vulnerability. The study concludes with a first look on the new Sendai Framework for Disaster Risk Reduction and how it aims to connect with adaptation and development.

✓ Herbert Olivecrona (1891–1980) singlehandedly founded Swedish neurosurgery. At the International Congress in Neurology in Bern in August, 1931, Harvey Cushing invited the cream of the world's medical society to a private banquet. Among the 28 specially invited guests was Herbert Olivecrona. At 40 years old, Olivecrona took his seat with pioneers such as Otfrid Foerster, Percival Bailey, Hugh Cairns, Geoffrey Jefferson, and Sir Charles Sherrington. This suggests that Cushing was impressed by the Swedish aristocrat's didactic deeds when he visited the Serafimer Hospital in Stockholm 2 years earlier. During the mid-1920's, the radiologist Erik Lysholm greatly improved the technique of ventriculography and, challenged by Olivecrona, his diagnostic neuroradiology became of superior quality. In the early 1930's, utilizing technical innovations of his own, Lysholm became a master at demonstrating and localizing posterior fossa tumors, which Olivecrona then operated on. Olivecrona's clinic became the mecca to which many scholars, thirsting for more knowledge, went on a pilgrimage. The international reputation of the clinic was founded, not on epoch-making discoveries, but by the resolute and practical application of methods already launched elsewhere and the exemplary organization that Olivecrona had established in collaboration with Lysholm. In spite of hardships and primitive working conditions, the clinic at the Serafimer Hospital gradually developed into the ideal prototype for a modern neurosurgical department. Olivecrona trained many colorful personalities who later were to lay the foundation for neurosurgery in their home countries; these included Wilhelm Tönnis of Germany, Edvard Busch of Denmark, and Aarno Snellman of Finland. Olivecrona was a true pioneer who made major contributions in practically all fields of conventional neurosurgery.

PurposeThe purpose of this study is to investigate professional identity development among management professionals through the lens of the ideal self and personal values.Design/methodology/approachDetailed career vision essays based on the ideal self and personal values of 48 participants ranging in age from 22 to 54 were analyzed using an inductive thematic analysis. A theory-based classification of their personal values, collected through a survey, was also conducted as a supplemental analysis.FindingsThe visions of older management professionals were less career-oriented, more holistic, involved in a greater multiplicity of career roles, had more clarity and placed higher emphasis on work–life balance and on developing others. The older participants also reported having fewer self-enhancement values.Originality/valueThe findings demonstrate the relevance of the ideal self as a lens to study identity development and advance our understanding of professional identity development in the context of modern careers.

Purpose This paper aims to analyse the ways the textual materials of job advertisements do the gendering for prospective expert positions and create a space for ambiquity/non-ambiquity in the gender labelling of this expertise. Expert positions are almost always openly announced and are important to organizations because they often lead to higher managerial positions. By gendering the prospective positions, the job advertisements bring forth repertoires strengthening the gendering of work and gendered expert employee positions. Design/methodology/approach This study draws on qualitative textual and visual data of open job advertisements for expert positions. The materials of the study are gathered from open job advertisements in two countries, i.e. Finland and Estonia with rather similar labour market structures in relation to gender positions but differing as regards their gender equality. Findings The analyses show that the gendering of expert work takes place in the job advertisements by rendering subtly gendered articulations, yet allowing for interpretative repertoires appear. The analysis reveals some differences in the formulations of the advertisements for expert jobs in the two countries. It also shows that in general the requirements for an ideal expert candidate are coated with superlatives that are gendered in rather stereotypical ways, and that the ideal candidates for highly expert jobs are extremely flexible and follows the ideal of an adaptable and plastic employee, willing to work their utmost. This paper contributes to the “doing gender” literature by adding an analysis of the textual gendering of ideal candidates for positions of expertise. Research limitations/implications The research materials do not expose all the issues pertinent to questions of the ideal gendered candidate. For instance, questions of ethnicity in relation to the definition of the ideal candidate cannot be studied with the data used for this study. Being an exploratory study, the results do not aim for generalizable results concerning job advertisements for expert positions. Originality/value This paper contributes to the “doing gender” and “gendering” literature by addressing the question of how and in what ways gender is defined and done for an expert positions prior the candidates are chosen to those jobs. It also offers new insights into the global construction of gendered expert jobs advertisements by addressing the topic with data from two countries. It further contributes to understanding the gendered shaping of expertise in the management literature.

Purpose – In 2011, a governmental initiative driven by the Department for Business Innovation and Skills invited the British Standards Institute (BSI) to write and publish a publicly available specification (PAS) for the reuse of waste electrical and electronic equipment entitled PAS 141. The specification's ambitious goals, chief among them to reduce the amount of e-waste generated in the UK, has prompted debate as to whether they are realistic and the extent to which they can be influenced by the certification. The purpose of this paper is to propose a comprehensive framework that can be used in future research to enhance understanding of the mechanisms by which the introduction of PAS 141 certification could lead to the fulfillment of its goals, that is, successful uptake. The authors believe this framework can serve as a roadmap for those interested in the investigation of this novel certification and its effect on the market for reusable electrical and electronic products. Design/methodology/approach – This paper is based on interviews with reuse organizations and first hand experience as a participant in the steering group that elaborated the certification being investigated, i.e. PAS 141. Findings – It is uncertain whether PAS 141 will fulfill its promises, which are, in the view of the authors, rather ambitious, e.g. reduce e-waste. Furthermore, more research is needed to examine the effect that the introduction of the certification has on the materialization of its goals, and on the complex inter-relationship that exist between the goals and what the authors define as intermediary necessary conditions. Research limitations/implications – This is the first attempt the outline the research needs that arise from the introduction of PAS-141, and the authors believe that there are other equally important questions that are yet to be presented and examined. Practical implications – This paper proposes 28 hypotheses which will help future work to empirically establish: the possibility of PAS-141 attaining its goals and the main necessary conditions for that to happen. This information is pivotal to determine whether the certification is working and to pinpoint opportunities for improvement. Social implications – This works contributes to the understanding of the role of certification on the market of reused products, which employs a large number of people, and in particular, whose coming from disadvantaged backgrounds. Originality/value – Although certification in general has been widely investigated in prior research, scant attention has been paid to certification in the context of electronic products. To the best of the knowledge, this is the first paper of its kind, as it is the first to examine certification in that context.

Purpose The purpose of this paper is to explore the sensitivity of economic efficiency rankings of water businesses to the choice of alternative physical and accounting capital input measures. Design/methodology/approach Data envelopment analysis (DEA) was used to compute efficiency rankings for government-owned water businesses from the state of Victoria, Australia, over the period 2005/2006 through 2012/2013. Differences between DEA models when capital inputs were measured using either: statutory accounting values (historic cost and fair value), physical measures, or regulatory accounting values, were scrutinised. Findings Depending on the choice of capital input, significant variation in efficiency scores and the ranking of the top (worst) performing firms was observed. Research limitations/implications Future research may explore the generalisability of findings to a wider sample of water utilities globally. Future work can also consider the most reliable treatment of capital inputs in efficiency analysis. Practical implications Regulators should be cautious when using economic efficiency data in benchmarking exercises. A consistent approach to account for the capital stock is needed in the determination of price caps and designing incentives for poor performers. Originality/value DEA has been widely used to explore the role of ownership structure, firm size and regulation on water utility efficiency. This is the first study of its kind to explore the sensitivity of DEA to alternative physical and accounting capital input measures. This research also improves the conventional performance measurement in water utilities by using a bootstrap procedure to address the deterministic nature of the DEA approach.

Purpose The purpose of this paper is to identify the best practices of industrial engineering (IE) programs that could be learnt and used at other educational institutions. Design/methodology/approach Nine IE programs in the USA are benchmarked using a conceptual framework that considers an educational program as a system consisting of a purpose, a curriculum, resources, and quality processes. The information used in benchmarking is collected from the program self-study reports, course catalogs, and websites which are available on the internet. Findings It is found that in spite of their diversity in history, missions, sizes, and reputations, the studied programs are rather unified in terms of purpose definition, curriculum formation, resource selection, and quality process usage. From the analysis, a template of IE curriculum is proposed. Research limitations/implications As the selection of the studied programs is based on the availability of the information, the findings may not be representative for IE programs in the USA. Future work can aim at comparing IE programs from various countries. Practical implications The findings could be used as benchmarks by IE schools interested in the improvement of operations. Originality/value A conceptual framework for benchmarking is proposed and proves useful for comparing educational programs. The findings represent the current best practices at IE schools in the USA.
