Method of electrical connector intermittent fault reproduction
Authors: Huakang Li , Lv Kehong , Qinmu Shen , Qiu Jing , Liu Guanjun 
Published: October 2018

PurposeThis paper aims to reproduce the electrical connector intermittent fault behaviours with step-up vibration stress while maintaining the integrity of the product.

Design/methodology/approachA dynamic model of an electrical connector under vibration is established for contact resistance analysis. Next, the dynamic characteristics of contact resistance are analysed, and cumulative damage theory is used to calculate the damage under different stresses during the intermittent fault reproduction test. To reduce damage and improve efficiency, the step-up stress is used for the reproduction test.

FindingsThe proposed method can reproduce the intermittent fault behaviour, and the step-up stress test is more efficient than the constant stress test.

Research limitations/implicationsStep-up stress is used for intermittent fault reproduction, and the quantitative relationships between intermittent fault and product damage can be further studied.

Practical implicationsIt is expected that the proposed methodology can help engineers to reproduce the intermittent fault behaviours to facilitate the detection and diagnosis of intermittent fault and to improve equipment safety.

Originality/valueThe mechanism of electrical connector reproduction is analysed and the step-up stress test is used for intermittent fault reproduction.
Collaborative authenticity
Authors: Orazi Davide Christian , Newton Fiona Joy 
Published: October 2018

PurposeEffective communication of information is central to integrated care systems (ICS), particularly between providers and care-consumers. Drawing on communication theory, this paper aims to investigate whether and why source effects increase positive evaluations of health-related messages among care-consumers.Design/methodology/approachA preliminary online survey (N = 525) establishes the discriminant validity of the measures used in the main experimental study. The main study (N = 116) examines whether identical messages disclosed to be created by different sources (i.e. institutional, care-consumer, collaborative) lead to different message evaluations, and whether source credibility and similarity, and message authenticity, explain this process.FindingsIn comparison to any other source, messages disclosed to be co-created are evaluated more positively by care-consumers. This effect occurs through a parallel serial mediation carried over by perceptions of source credibility and source similarity (parallel, first serial-level mediators) and message authenticity (second serial-level mediator).Practical implicationsThe findings offer guidelines for leveraging source effects in ICS communication strategies, signaling how collaborative message sources increase the favorableness of health message evaluations.Originality/valueThis research demonstrates the efficacy of drawing on marketing communication theory to build ICS communication capacity by showing how re-configuring the declared source of informational content can increase positive evaluations of health-related messages. In so doing, this research extends existing literature on message authenticity by demonstrating its key underlying role in affecting message evaluations.
Using partial least squares structural equation modeling in hospitality and tourism
Authors: Usakli Ahmet , Kucukergin Kemal Gurkan 
Published: October 2018

PurposeThe purpose of this study is to review the use of partial least squares-structural equation modeling (PLS-SEM) in the field of hospitality and tourism and thereby to assess whether the PLS-SEM-based papers followed the recommended application guidelines and to investigate whether a comparison of journal types (hospitality vs tourism) and journal qualities (top-tier vs other leading) reveal significant differences in PLS-SEM use.Design/methodology/approachA total of 206 PLS-SEM based papers published between 2000 and April 2017 in the 19 SSCI-indexed hospitality and tourism journals were critically analyzed using a wide range of guidelines for the following aspects of PLS-SEM: the rationale of using the method, the data characteristics, the model characteristics, the model assessment and reporting the technical issues.FindingsThe results reveal that some aspects of PLS-SEM are correctly applied by researchers, but there are still some misapplications, especially regarding data characteristics, formative measurement model evaluation and structural model assessment. Furthermore, few significant differences were found on the use of PLS-SEM between the two fields (hospitality and tourism) and between the journal tiers (top-tier and other leading).Practical implicationsTo enhance the quality of research in hospitality and tourism, the present study provides recommendations for improving the future use of PLS-SEM.Originality/valueThe present study fills a sizeable gap in hospitality and tourism literature and extends the previous assessments on the use of PLS-SEM by providing a wider perspective on the issue (i.e. includes both hospitality and tourism journals rather than the previous reviews that focus on either tourism or hospitality), using a larger sample size of 206 empirical studies, investigating the issue over a longer time period (from 2000 to April, 2017, including the in-press articles), extending the scope of criteria (guidelines) used in the review and comparing the PLS-SEM use between the two allied fields (hospitality and tourism) and between the journal tiers (top-tier and other leading).
Effective quality systems: implementation in Australian public hospitals
Authors: Leggat Sandra G. , Balding Cathy 
Published: October 2018

Purpose
The purpose of this paper is to review the implementation of seven components of quality systems (QSs) linked with quality improvement in a sample of Australian hospitals.

Design/methodology/approach
The authors completed a systematic review to identify QS components associated with measureable quality improvement. Using mixed methods, the authors then reviewed the current state of these QS components in a sample of eight Australian hospitals.

Findings
The literature review identified seven essential QS components. Both the self-evaluation and focus group data suggested that none of the hospitals had all of these seven components in place, and that there were some implementation issues with those components that were in use. Although board and senior executives could point to a large number of quality and safety documents that they felt were supporting a vision and framework for safe, high-quality care, middle managers and clinical staff described the QSs as compliance driven and largely irrelevant to their daily pursuit of safe, high-quality care. The authors also found little specific training in quality improvement for staff, lack of useful data for clinicians on the quality of care they provide and confusion about how organisational QSs work.

Practical implications
This study provides a clearer picture of why QSs are not yet achieving the results that boards and executives want to achieve, and that patients require.

Originality/value
This is the first study to explore the implementation of QSs in hospitals in-depth from the perspective of hospital staff, linking the findings to the implementation of QS component identified in the literature.
Teaching introductory macroeconomics during the Greek financial crisis
Authors: Marangos John 
Published: October 2018

Purpose
The purpose of this paper is to determine how including the Greek financial crisis in teaching introductory macroeconomics benefits students.

Design/methodology/approach
The methodology is based on the responses of a recent survey administered to students at a university in Greece.

Findings
An eclectic approach that distinguishes various economic theories and methodologies, mainly neoclassical and Keynesian, can provide a pedagogical way of teaching introductory macroeconomics, allowing students to use their everyday personal experiences in determining the most “suitable” theory in explaining the crisis.

Originality/value
To the author’s knowledge, such an exercise of discovering students’ perceptions of teaching an introductory macroeconomics Substitute with course during the global financial crisis has not yet been attempted.

It recommends empirical studies to be conducted to inform future practices for doctoral students.Practical implicationsThis paper offers four areas of training to be considered by librarians and faculty advisers to better prepare scholars for their future.Originality/valueThis paper presents a distinctive synthesis of the types of information literacy and digital literacy skills needed by graduate students.
Corporate real estate strategies and organizational culture
Authors: Nase Ilir , Arkesteijn Monique 
Published: October 2018

PurposeThe purpose of this paper is to investigate how strategic corporate real estate (CRE) management varies across different types of organizational culture. Additionally, the authors examine how a set of well-established strategies is categorized by CRE executives and investigate whether there have been any changes in priorities of managers’ rating in importance of these strategies compared to a post-GFC study.

Design/methodology/approachA wide-scale survey of CRE managers was undertaken in summer 2016. Two key components of the survey are namely importance scoring of CRE strategies after the framework of Gibler and Lindholm (2012) and organizational culture assessment based on the competing values framework of Cameron and Quinn (2006). Analysis of CRE strategy importance is undertaken based on the average score comparison per each cultural family, and additional features are reported based on the industry sector, firm size and CRE department size. Principal component analysis is used to provide statistical evidence on the grouping of CRE strategies by practitioners.

FindingsEmpirical evidence points toward a clear division on the organizational culture dimension that differentiates effectiveness criteria of flexibility and discretion from stability and control. More specifically, clan and adhocracy cultural types prioritize employee-centric CRE strategies, whereas hierarchy and market cultures consider “Reducing real estate cost” as their single most influential strategy.

Research limitations/implicationsThe competing values framework has been adapted from the original ipsative scoring process to reflect the fact that only one respondent per firm assesses their organization’s culture.

Practical implicationsThe findings of this study are useful to CRE managers striving for maximum strategic fit within their firms as they unveil clear patterns of CRE strategy prioritization among different organizational culture types.

Originality/valueTo the authors’ best knowledge, this is the first study that analyzes the inter-relationships among CRE strategies and organizational culture variations. Additionally, the paper provides a categorization of CRE strategies through statistical methods that follow a clear pattern based on the scope of each strategy.
Planar array magnetic induction tomography further improvement
Authors: Li F. , Soleimani M. , Abascal J. 
Published: October 2018

Purpose
Magnetic induction tomography (MIT) is a tomographic imaging technique with a wide range of potential industrial applications. Planar array MIT is a convenient setup but unable to access freely from the entire periphery as it only collects measurements from one surface, so it remains challenging given the limited data. This study aims to assess the use of sparse regularization methods for accurate position and depth detection in planar array MIT.

Design/methodology/approach
The most difficult challenges in MIT are to solve the inverse and forward problems. The inversion of planar MIT is severely ill-posed due to limited access data. Thus, this paper posed a total variation (TV) problem and solved it efficiently with the Split Bregman formulation to overcome this difficulty. Both isotropic and anisotropic TV formulations are compared to Tikhonov regularization with experimental MIT data.

Findings
The results show that Tikhonov method failed or underestimated the object position and depth. Both isotropic and anisotropic TV led to accurate recovery of depth and position.

Originality/value
There are numerous potential applications for planar array MIT where access to the materials under testing is restrict. Sparse regularization methods are a promising approach to improving depth detection for limited MIT data.
Creative tourism: South African township explorations
Authors: Booyens Irma , Rogerson Christian M. 
Published: October 2018

Purpose
This purpose of this paper is to explore creative forms of tourism in South African townships. The developmental potential of slum tourism is contested. One challenge is to reconfigure extant forms of slum tourism into more sustainable alternatives that emphasise combatting poverty through generating economic opportunities and upgrading slum spaces. It is argued that creative tourism has a vital potential role in reshaping slum tourism in a responsible manner.

Design/methodology/approach
This exploratory investigation identifies emerging examples of creative forms of tourism in two case study townships: Soweto in Johannesburg and Langa in Cape Town. Current examples and potential for future development are interrogated, and areas for further research are outlined.

Findings
Emerging examples of creative tourism in townships with an emphasis on creative participatory experiences, creative spaces and creative cultural events are identified. It is suggested that creative tourism offerings based on cultural resources are under-developed, and potential exists for innovating and expanding creative tourism offerings in townships as a response to latent international and domestic visitor demands.

Social implications
Creative township tourism provides a number of avenues for catalysing economic opportunities; ensuring that locals benefit directly, upgrading physical township spaces and offering alternatives to voyeuristic forms of slum tourism by enhancing the authenticity of visitor experiences.

Originality/value
A new perspective on slum tourism is offered. Creative slum tourism has not been interrogated in the existing slum tourism and creative tourism literatures. This paper calls for more comprehensive empirical investigation on creative forms of tourism in townships and also in slums.
How to retire like a Soviet person: informality, household finances, and kinship in financialized Kazakhstan
Authors: Begim Ainur 
Published: October 2018

AbstractWhat motivates financially savvy and well‐to‐do Kazakhstanis to invest in illegal financial products peddled by informal financial consultants? This article examines how such consultants capitalize on citizens’ discontent with the state and its management of the financial sphere and position their products as means of achieving socialist‐era security through Western financial technologies. By attending to the emergent space between idealized socialism and capitalism, this article grounds finance in kin relations, gender inequities, and local economic and political histories and explores how socialist conceptions of retirement and money management are reimagined and practised in relation to state‐led financialization.
Analyzing the Evolution of a Digital Technology Intervention: One Laptop Per Child in a Remote Papua New Guinea Community
Authors: Saxe Geoffrey B. , de Kirby Kenton 
Published: October 2018

AbstractThis article offers an ethnographic account of the evolution of a One Laptop per Child intervention program in Oksapmin communities (Papua New Guinea). The analysis examines the intervention’s evolution as historically contingent, revealing how interdependent actions of multiple stakeholders create and partially resolve perceived threats to the program’s continuation under changing circumstances. The approach contrasts with those that explain the success or failure of interventions based upon “fit” to cultural context.
Dropping to escape: a review of an under‐appreciated antipredator defence
Authors: Humphreys Rosalind K. , Ruxton Graeme D. 
Published: October 2018

AbstractDropping is a common antipredator defence that enables rapid escape from a perceived threat. However, despite its immediate effectiveness in predator–prey encounters (and against other dangers such as a parasitoid or an aggressive conspecific), it remains an under‐appreciated defence strategy in the scientific literature. Dropping has been recorded in a wide range of taxa, from primates to lizards, but has been studied most commonly in insects. Insects have been found to utilise dropping in response to both biotic and abiotic stimuli, sometimes dependent on mechanical or chemical cues. Whatever the trigger for dropping, the decision to drop by prey will present a range of inter‐related costs and benefits to the individual and so there will be subtle complexities in the trade‐offs surrounding this defensive behaviour. In predatory encounters, dropping by prey will also impose varying costs and benefits on the predator – or predators – involved in the system. There may be important trade‐offs involved in the decision made by predators regarding whether to pursue prey or not, but the predator perspective on dropping has been less explored at present. Beyond its function as an escape tactic, dropping has also been suggested to be an important precursor to flight in insects and further study could greatly improve understanding of its evolutionary importance. Dropping in insects could also prove of significant practical importance if an improved understanding can be applied to integrated pest‐management strategies. Currently the non‐consumptive effects of predators on their prey are under‐appreciated in biological control and it may be that the dropping behaviour of many pest species could be exploited via management practices to improve crop protection. Overall, this review aims to provide a comprehensive synthesis of the current literature on dropping and to raise awareness of this fascinating and widespread behaviour. It also seeks to offer some novel hypotheses and highlight key avenues for future research.
Die histologische intraläsionale Heterogenität aktinischer Keratosen als Zeichen von Feldkanzerisierung
Authors: Schmitz Lutz , Stücker Markus , Gambichler Thilo , Stockfleth Eggert , Dirschka Thomas 
Published: October 2018

ZusammenfassungHintergrund/ZieleDie histologische Heterogenität innerhalb einzelner Aktinischer Keratosen (AKs) wurde beschrieben und könnte als zusätzliches Merkmal zur Charakterisierung von AKs dienen. Unser Ziel war es daher die histologische Heterogenität von AKs anhand unterschiedlicher Klassifikationen zu untersuchen und zu quantifizieren.Material und MethodenWir bewerteten die histologischen Charakteristika von 3‐mm‐Biopsien von AK‐Läsionen der Kopfhaut oder des Gesichtes. Dazu wurde die basale Proliferation (PRO I–III) und der histologischen Grad (AK I–III) sowie die Gesamtklassifikation der jeweiligen Läsion bestimmt.ErgebnisseVon den 305 untersuchten Läsionen wurden 48 (15,7 %) als AK I, 152 (49,8 %) als AK II und 105 (34,4 %) als AK III klassifiziert. 33 AKs (10,8 %) zeigten keine basale Proliferation, 94 (30,8 %) wurden als PRO I, 99 (32,5 %) als PRO II und 79 (25,9 %) als PRO III eingestuft. Es zeigte sich jeweils ein AK‐Grad in 94 (30,8 %) bzw. ein PRO‐Grad in 104 (34,1 %) Fällen, jeweils 2 Grade in 170 (55,7 %) bzw. 168 (55,1 %) Fällen und gleichzeitig alle 3 Grade in 41 (13,4 %) bzw. 33 (10,8 %) der Fälle (Chi‐Quadrat‐Test, p < 0,0001).SchlussfolgerungenIn Analogie zur klinischen Variabilität einer Feldkanzerisierung zeigen selbst einzelne AKs innerhalb kleinster Abschnitte eine starke Heterogenität der histologischen Graduierung. Diese Variationsbreite der AK‐Einteilung spiegelt die Heterogenität der Feldkanzerisierung wider und kann als zusätzliches histologisches Merkmal dienen.
The Migration Archipelago: Social Navigation and Migrant Agency
Authors: Triandafyllidou Anna 
Published: October 2018

AbstractThis paper is inscribed into a new line of scholarly work seeking to cast light to the ways in which migrants convert their motivations into action within a policy framework that is characterised by many restrictions and limited opportunities to move. Drawing on recent fieldwork (2013‐2014) on irregular migrants from Afghanistan, Albania, Georgia, Pakistan and the Ukraine, in Greece, we investigate how they perceive opportunities and navigate restrictions eventually crossing borders whether unlawfully (from unguarded border areas or with fake documentation) or legally (abusing the terms of their entry/stay). The paper adopts the notion of social navigation as a heuristics tool to conceptualise the social, temporal and spatial character of the migration journey, its nodal points, and the interaction of migrants with different actors and factors that shape their migration plans and explores different types of migrant agency (recuperation, resilience and resistance) developed during the navigation process.
Scattered Limbs: Capitalists, Kin, and Primitive Accumulation in Brazil's Cacao Lands, 1950s–1970s
Authors: DeVore Jonathan 
Published: October 2018

ResumoEste artigo analisa um land grab que ocorreu na região cacaueira da Bahia entre as décadas de 1950 e 1970, despojando centenas de pessoas, muitas delas afrodescendentes, que tinham se refugiado nas florestas da região após a abolição da escravidão. O land grab foi inaugurado por um dos mais importantes capitalistas brasileiros, Norberto Odebrecht, cuja ascensão no sul da Bahia foi pouco tratada pela historiografia. O artigo descreve a chegada de Odebrecht à região, a expansão da extração de madeira e do cultivo de borracha industrial, e os processos que levaram as famílias locais a perderem suas terras e serem transformadas em um proletariado rural. Embora o caso forneça um exemplo clássico do que Marx chama de “acumulação primitiva de capital,” o relato chama a atenção para formas menos teorizadas de despossessão, caracterizadas recentemente como “intimate exclusions,” e casos inesperados de solidariedade interseccional. A conclusão destaca a realidade semiótica da narratividade, atentando para as consequências econômicas e políticas das narrativas de despossessão.
