AbstractThis paper investigates the design and development of bio-inspired suture pins that would reduce the insertion force and thereby reducing the pain in the patients. Inspired by kingfisher's beak and porcupine quills, the conceptual design of the suture pin is developed by using a unique ideation methodology that is proposed in this research. The methodology is named as Domain Integrated Design, which involves in classifying bio-inspired structures into various domains. There is little work done on such bio-inspired multifunctional aspect. In this research we have categorized the vast biological functionalities into domains namely, cellular structures, shapes, cross-sections, and surfaces. Multi-functional bio-inspired structures are designed by combining different domains. In this research, the hypothesis is verified by simulating the total deformation of tissue and the needle at the moment of puncture. The results show that the bio-inspired suture pin has a low deformation on the tissue at higher velocities at the puncture point and low deformation in its own structure when an axial force (reaction force) is applied to its tip. This makes the design stiff and thus require less force of insertion.

Purpose The purpose of this paper is to discuss the role of digital forensics in an evolving environment of cyber laws giving attention to Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) countries, comprising Bangladesh, India, Myanmar, Sri Lanka, Thailand, Nepal and Bhutan, in a dynamic global context. Design/methodology/approach This study uses a case study approach to discuss the digital forensics and cyber laws of BIMSTEC countries. The objective of the study was expected to be achieved by referring to decided cases in different jurisdictions. Cyber laws of BIMSTEC countries were studied for the purpose of this study. Findings The analysis revealed that BIMSTEC countries are required to amend legislation to support the growth of information technology. Most of the legislation are 10-15 years old and have not been amended to resolve issues on cyber jurisdictions. Research limitations/implications This study was limited to the members of the BIMSTEC. Originality/value This paper is an original work done by the authors who have discussed the issues of conducting investigations with respect to digital crimes in a rapidly changing environment of information technology and deficient legal frameworks.

PurposeThis paper aims to determine the stage of the life cycle where the trucks of a waste collection fleet from a Colombian city are located through a reliability approach. The reliability analysis and the evaluation of curve of operational costs allow to know the moment in which it is necessary to make decisions regarding an asset, its maintenance or possible replacement.Design/methodology/approachFor a dataset presented as maintenance work orders, the time to failures (TTFs) for each vehicle in the fleet were calculated. Then, a probability density function for those TTFs was fitted to locate each vehicle in a region of the bathtub curve and to calculate the reliability of the whole fleet. A general functional analysis was also developed to understand the function of the vehicles.FindingsIt was possible to determine that the largest proportion of the fleet was in the final stage of the life cycle, in this sense, the entire fleet represent critical assets which in most of cases could be worth replacement or overhaul.Originality/valueIn this study, an address is exposed for the identification of critical equipment by reliability and statistical analysis. This analysis is also integrated with the maintenance management process. This is a broadly interested topic since it allows to support the maintenance and operational decision-making process, indicating the focus of resource allocation all over the entire asset life cycle.

Practical Implications

Purpose – This paper aims to assess the facility management (FM) practices in public and private buildings, and compare the practices in both the buildings. This paper critically analysed the current FM practices and explored the range of contributions that the facility manager could offer in both public and private buildings. Design/methodology/approach – A case study of 19 public and 20 private buildings in Ibadan and Akure cities was carried out in this paper. Findings – The paper revealed that the state of FM awareness is higher in private buildings than in public buildings and that FM practices in the two types of buildings are significantly related, but the extent of usage of FM methods are significantly different in the buildings. It was also observed in the research that corrective and responsive FM practices are the order of the day in both public and private buildings. Practical implications – The paper acknowledged that the involvement of the facility manager with the integrated design team if implemented efficiently will contribute in reducing the need for major repairs and alterations in the lifespan of the facility and that the practices of preventive, planned and immediate responsive approaches would better the life of buildings. Social implications – The paper recommended that stricter action should be taken to mitigate against the poor handling and misuse of buildings by users, as it affects negatively the success story of FM in the country. Originality/value – This paper reached out to address the lack of proper FM in the country.

Beckett's famous claim that his writing seeks to ‘work on the nerves of the audience, not the intellect’ points to the centrality of affect in his work. But while his writing's affective quality is widely acknowledged by readers of his work, its refusal of intellect has made it difficult to take fully into account in scholarly work on Beckett. Taking Beckett's 1967 short prose text Ping as a case study, this essay is an attempt to take the affective qualities of Beckett's writing seriously and to consider the implications of his affectively dense writing for his texts’ relationship to history. I argue that Ping's affect emerges from the rhythms of its prose, producing a highly ‘speakable’ text in which affect precedes interpretation. In Ping, however, this affective rhythmic patterning is portrayed as mechanical, the product of the machinic ‘ping’ that punctuates the text and the text's own mechanical rhythms, demanding the active involvement of the reader. The essay concludes by arguing that Ping's mechanised affect is a specifically historical feeling. Arising from a specifically twentieth-century anxiety about technology's tendency to evacuate ‘natural’ emotion in favour of inhuman affect, it participates in a tradition of affectively resonant but curiously blank or indifferent performances of cyborg embodiment. Read in this historical light, Ping's implication of the reader in the production of its mechanised affect grants it, from our contemporary perspective, an archival quality. At the same time, it asks us to broaden the way in which we understand the Beckettian text's relationship to history, pointing to the existence of a more complex and recursive relationship between literature, its historical moment, and our contemporary moment of reading. Such a post-archival historicism sees texts as generated by but not bound to their historical moments of composition, and understands the moment of reception as an integral, if shifting, part of the text's history.

Intergenerational Knowledge

Purpose This paper aims to develop a better understanding of intergenerational knowledge transfer (IKT) practices by adopting a context-related and comparative perspective. Design/methodology/approach A qualitative case study design involving 83 interviews and non-participative observation in German and Quebec organizations has been chosen. Findings Two distinctive archetypes of IKT emerge from both national contexts: “we-individualizing” (Germany) and “I-connecting” (Quebec), leading to an eightfold taxonomy of IKT practices. Research limitations/implications This research is limited to young and senior workers and to high-tech sectors. Originality/value Comparative and inductive study of IKT, adaptation of IKT practices to national contexts, retaining younger workers. This inductive and comparative study allows a better adaptation of IKT practices to national contexts and therefore a better retention of younger workers.

Challenges And Opportunities

Purpose – This paper is based on a crop insurance implementation currently undergoing in Haiti. The purpose of this paper is to present the development of a program tailored to rice production in the Artibonite Valley, the challenges and opportunities that are arising from the exercise as well as pitfalls and ways to avoid them. Design/methodology/approach – The Système de Financement et d’Assurances Agricoles en Haïti’s approach for the development of crop insurance is in accordance with 13 concepts considered essential in the implementation of agricultural insurance programs. The case study is presented through each of these 13 fundamental concepts. Findings – The paper provides an insight on challenges any organization will face when implementing crop insurance for smallholder farmers. It points out notably that close collaboration of executing agencies with local partners is essential from data collection through insurance development and delivery and that all participants should receive a specific training tailored to their level of education and understanding. Social implications – Haiti is one of the poorest countries on the planet. Smallholder farmers could benefit a lot from crop insurance. It could help them stabilize their income when facing crop losses due to natural hazards or uncontrollable natural events. Originality/value – This paper fulfills an identified need to share real case studies exposing challenges faced when implementing crop insurance for smallholder farmers.

The Impact

The study of social classes in the nineteenth century requires the development of conceptual tools able to explain the impact of the Conquest on the pre-existant social structures in determining transformations of the class structure during the subsequent decades.This article examines the work done on this question by Marxist writers. The author criticizes certain conclusions which have been drawn and which suggest deficiencies at a theoretical level. The objections relate to the marked tendency of these conclusions to perceive the structural effects of the Conquest in terms of the formation of a double-class structure characterized by “ethnic origins.” Specifically, the author challenges the notion of the division itself, as well as the criterion on which the division is based.The author proposes that an analysis centred upon the concepts relating to a problem of the transition and linkage of different modes of production permits a more satisfying interpretation, if accompanied by a certain number of considerations of the “upside” and “downside” of the Conquest. To this end, the argument is based on a characterization of New France in terms of the domination of the relations of production of the feudal type and on an analysis of metropolitan centres with intent to evaluate their level of capitalist development at the moment of their respective colonial penetration in Canada. The results of this approach permit one to posit the existence of a single-class structure, characterized principally by the existence of elements connecting diverse modes and forms of production, whose origin reflects the unequal state of economic development in the two metropolitan centres.The empirical demonstration rests on the census data of 1851–1852 and on the complementary information drawn from the works of historians.
