Recent theoretical developments linking degradation to the thermodynamic concept of entropy have allowed a new approach to modeling all types of degradation. The theory has been successfully applied to wear, fatigue, and numerous other forms of degradation and experimentation has confirmed its applicability to modeling the mechanical degradation of lubricating grease. This paper overviews the mechanical degradation of grease, discusses past and present modeling techniques, shows how new techniques can be used to predict grease life, and provides suggestions for future research.

Theoretical Developments

Studies of international institutions, organizations, and regimes have consistently appeared in the pages of International Organization. We review the theoretical and empirical work on international institutions and identify promising directions for the institutionalist research program. Early studies of international institutions were rich with empirical insights and often influenced by theoretical developments in other fields of political science, but lacking an overarching analytical framework they failed to produce a coherent body of scholarship. Current efforts to reinvigorate the study of international institutions draw on a new body of theory about domestic institutions. We argue that the assumptions of this new approach to institutions are more appropriate to international studies than those of earlier attempts to transfer theories across levels of analysis. We suggest that the most productive questions for future research will focus on specifying alternative mechanisms by which institutions can influence outcomes and identify particular sets of questions within this agenda that are especially promising.

Purpose Neutrality is a much debated value in library and information science (LIS). The “neutrality debate” is characterised by opinionated discussions in contrasting contexts. The purpose of this paper is to fill a gap in the literature by bringing these conceptions together holistically, with potential to deepen understanding of LIS neutrality. Design/methodology/approach First, a literature review identified conceptions of neutrality reported in the LIS literature. Second, seven phenomenographic interviews with LIS professionals were conducted across three professional sectors. To maximise variation, each sector comprised at least one interview with a professional of five or fewer years’ experience and one with ten or more years’ experience. Third, conceptions from the literature and interviews were compared for similarities and disparities. Findings In four conceptions, each were found in the literature and interviews. In the literature, these were labelled: “favourable”, “tacit value”, “social institutions” and “value-laden profession”, whilst in interviews they were labelled: “core value”, “subservient”, “ambivalent”, and “hidden values”. The study’s main finding notes the “ambivalent” conception in interviews is not captured by a largely polarised literature, which oversimplifies neutrality’s complexity. To accommodate this complexity, it is suggested that future research should look to reconcile perceptions from either side of the “neutral non-neutral divide” through an inclusive normative framework. Originality/value This study’s value lies in its descriptive methodology, which brings LIS neutrality together in a holistic framework. This framework brings a contextual awareness to LIS neutrality lacking in previous research. This awareness has the potential to change the tone of the LIS neutrality debate.

The Relationship

Purpose – The purpose of this paper is to provide insights into the relationship between dynamic capabilities and innovation capabilities. It links dynamic capability with innovation capability and indicates the ways they can be related. Design/methodology/approach – The relationships between dynamic and innovation capability were investigated through a systematic literature review. Findings – The review indicates that common characteristics exist between of the both fields, which demonstrate six relationships. Additionally, findings show some inconsistencies and even contradictions. Originality/value – In this paper, the authors have compared dynamic capabilities, a relatively new approach in the field of strategic management, with innovation capabilities, a widely recognised crucial domain for sustained competitiveness. Since both areas address issues that are essential to today's environment, future research should seek to clarify both concepts, by undertaking some new research and developing comprehensive and unambiguous framework.

PurposeThis paper aims to explore how purchasing could respond to disruptive technologies by examining the assumptions underlying purchasing strategic alignment and purchasing maturity through a contingency lens.Design/methodology/approachThis study uses a systematic review across purchasing maturity and purchasing strategic alignment literature. This is supplemented with exploratory case studies to include practitioners’ views.FindingsThis research demonstrates that neither purchasing maturity nor purchasing strategic alignment are suitable approaches to respond to disruptive technologies. Purchasing maturity does not allow purchasing managers to select relevant practices. It also shows no consideration of any contingencies, which practitioners highlight as important for the selection of practices. Purchasing strategic alignment includes the company strategy as a contingency but does not provide any practices to choose from. It does not include any other contextual contingencies considered important by practitioners. The findings indicate that linking the two research streams may provide a more suitable approach to responding to disruptive technologies.Research limitations/implicationsThis research demonstrates the requirement to develop a new approach to responding to disruptive technologies, by linking purchasing maturity and purchasing strategic alignment to contextual contingencies. This is a currently unexplored approach in academic literature, which refutes the generally accepted premise that higher maturity unilaterally supports a better positioning towards technological disruption. This research also highlights a requirement for practitioners to shift their approach to “best practices”.Originality/valueThis is the first research to systematically review the relationships between purchasing maturity and purchasing strategic alignment. It adds to contingency theory by suggesting that purchasing maturity models can support the achievement of strategic alignment. Also, future research directions are suggested to explore these relationships.

Neurons in the brain represent information in their collective activity. The fidelity of this neural population code depends on whether and how variability in the response of one neuron is shared with other neurons. Two decades of studies have investigated the influence of these noise correlations on the properties of neural coding. We provide an overview of the theoretical developments on the topic. Using simple, qualitative, and general arguments, we discuss, categorize, and relate the various published results. We emphasize the relevance of the fine structure of noise correlation, and we present a new approach to the issue. Throughout this review, we emphasize a geometrical picture of how noise correlations impact the neural code. Expected final online publication date for the Annual Review of Neuroscience, Volume 44 is July 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Several recent model tests of tension leg platforms (TLP's) are described. Some new and challenging design problems which are unique to tension leg platforms have become the focal points of these tests. These have required the development of new modeling techniques and methods of data processing. A general review of TLP characteristics and modeling requirements is presented along with a description of recent test programs and modeling techniques. Research areas of particular interest in the recent tests are described and some recommendations for future research are made.

Ways Of Thinking

For the individuals participating in the Mesolithic–Neolithic transition, one question must have recurrently emerged as a prime concern: ‘Should I mistrust traditions and consider innovations’? This concern encompassed the introduction of new material culture and new techniques of obtaining food. It also involved new ways of conceiving the world and people's place in it. And it was affected by important – sometimes catastrophic – changes in the physical environment. It must be emphasized that the question of whether to mistrust traditions and consider innovations is not only a matter of concern for prehistoric actors. It is also important for those who are making prehistory today. As is presented in this chapter, the facts presented for south Scandinavia have been variously interpreted as indicating the rapid introduction of a ‘Neolithic’ package with new ways of thinking and acting, as well as reflecting a mixture of traditions and gradually incorporated innovations. Future research into the transition should focus on combining new problem-oriented excavation with fresh ideas about how the transition from the Mesolithic to the Neolithic occurred.

Recourse to auxiliary disciplines has greatly contributed to the ways in which biblical scholars seek to elucidate various dimensions of meaning in textual constructions of dreams and dreaming in the Old Testament. The original contribution this article hopes to make to the ongoing research on associated oneirocritic topoi is to propose the so-called philosophy of dreaming as a potential dialogue partner to supplement already available perspectives within the multidisciplinary discussion. At present, there is no descriptive philosophical approach exclusively devoted to the identification and clarification of the folk-philosophical assumptions implicit in oneirocritic materials as conditions of their possibility. By way of comparative-philosophical commentary, the article features a brief introduction to the related research within Old Testament studies, an overview of the history and problems of the auxiliary subject, and an illustration of how the new approach might look when applied to texts involving ‘oneirophany’ (Gn 15:1–21, 20:3–6, 28:11–17 and 1 Ki 3:5–15). The study concludes with a few remarks on the limits of the proposal and suggestions for more extensive and in-depth future research in related and alternative areas.

AbstractDynamic consent (DC) was originally developed in response to challenges to the informed consent process presented by participants agreeing to ‘future research’ in biobanking. In the past 12 years, it has been trialled in a number of different projects, and examined as a new approach for consent and to support patient engagement over time. There have been significant societal shifts during this time, namely in our reliance on digital tools and the use of social media, as well as a greater appreciation of the integral role of patients in biomedical research. This paper reflects on the development of DC to understand its importance in an age where digital health is becoming the norm and patients require greater oversight and control of how their data may be used in a range of settings. As well as looking back, it looks forwards to consider how DC could be further utilised to enhance the patient experience and address some of the inequalities caused by the digital divide in society.

The effects of acupuncture facilitating neural plasticity for treating diseases have been identified by clinical and experimental studies. In the last two decades, the application of neuroimaging techniques in acupuncture research provided visualized evidence for acupuncture promoting neuroplasticity. Recently, the integration of machine learning (ML) and neuroimaging techniques becomes a focus in neuroscience and brings a new and promising approach to understand the facilitation of acupuncture on neuroplasticity at the individual level. This review is aimed at providing an overview of this rapidly growing field by introducing the commonly used ML algorithms in neuroimaging studies briefly and analyzing the characteristics of the acupuncture studies based on ML and neuroimaging, so as to provide references for future research.
