Mobile phone user authentication with grip gestures using pressure sensors
Authors: Murao Kazuya , Tobise Hayami , Terada Tsutomu , Iso Toshiki , Tsukamoto Masahiko , Horikoshi Tsutomu 
Published: August 2015

Purpose
– User authentication is generally used to protect personal information such as phone numbers, photos and account information stored in a mobile device by limiting the user to a specific person, e.g. the owner of the device. Authentication methods with password, PIN, face recognition and fingerprint identification have been widely used; however, these methods have problems of difficulty in one-handed operation, vulnerability to shoulder hacking and illegal access using fingerprint with either super glue or facial portrait. From viewpoints of usability and safety, strong and uncomplicated method is required.

Design/methodology/approach
– In this paper, a user authentication method is proposed based on grip gestures using pressure sensors mounted on the lateral and back sides of a mobile phone. Grip gesture is an operation of grasping a mobile phone, which is assumed to be done instead of conventional unlock procedure. Grip gesture can be performed with one hand. Moreover, it is hard to imitate grip gestures, as finger movements and grip force during a grip gesture are hardly seen by the others.

Findings
– The feature values of grip force are experimentally investigated and the proposed method from viewpoint of error rate is evaluated. From the result, this method achieved 0.02 of equal error rate, which is equivalent to face recognition.

Originality/value
– Many researches using pressure sensors to recognize grip pattern have been proposed thus far; however, the conventional works just recognize grip patterns and do not identify users, or need long pressure data to finish confident authentication. This proposed method authenticates users with a short grip gesture.
Owner-employee relations in small firms
Authors: Ntalianis Filotheos , Dyer Linda , Vandenberghe Christian 
Published: August 2015

Purpose– The purpose of this paper is to shed light on the type of exchange relationship that small business owners establish with their employees. In particular, this study examines how the personality trait of “conscientiousness” among small business owners relates to relational “psychological contracts,” breach and violation that develop between owners and employees.Design/methodology/approach– This was a quantitative survey design conducted in Canada. Participants were 253 employees and the 50 small firm owners for whom they worked.Findings– Results indicate that owner conscientiousness was positively associated with a relational psychological contract with employees and perceived breach mediated a negative relationship between owner-rated relational contract obligations and feelings of contract violation among employees. Owner-rated relational contract obligations also mediated a negative relationship between owner conscientiousness and employee perceptions of breach and violation.Practical implications– Given the link between conscientiousness and relational contracts, small business owners who get involved in selection and training ought to present to the newly hired employees an accurate picture of their role and job requirements in order to create successful organizations. In addition, less conscientious business owners, through training, should try to develop further skills, such as goal setting and performance appraisal, in order to increase their ability to establish effective relationships (i.e. relational contracts).Originality/value– The current study is an initial attempt toward a better understanding of exchange relationships in small firms, thus strengthening the links between organizational behavior and small business research. It also contributes a quantitative perspective on issues that have typically been explored qualitatively.
Changes in work intensification and intensified learning: challenge or hindrance demands?
Authors: Korunka Christian , Kubicek Bettina , Paškvan Matea , Ulferts Heike 
Published: August 2015

Purpose
– Increasing speed in many life domains is currently being discussed under the term “social acceleration” as a societal phenomenon which not only affects western societies, but may also lead to job demands arising from accelerated change. Demands such as work intensification and intensified learning and their changes over time may increase emotional exhaustion, but may also induce positive effects. The purpose of this paper is to examine how increases in demands arising from accelerated change affect employee well-being.

Design/methodology/approach
– A total of 587 eldercare workers provided data on work intensification and intensified learning as well as on exhaustion and job satisfaction at two points in time.

Findings
– Work intensification was negatively related to future job satisfaction and positively related to future emotional exhaustion, whereas intensified learning was positively associated with future job satisfaction and negatively with future emotional exhaustion.

Social implications
– Intensified demands represents a growing social as well as work-specific challenge which needs to be addressed by practitioners.

Originality/value
– Using a longitudinal perspective this study is the first to examine the relationship of increases in work intensification and intensified learning with job satisfaction and emotional exhaustion at work.
Work-home interference and work values in Greater China
Authors: Lu Chang-qin , Wang Bei , Siu Oi-ling , Lu Luo , Du Dan-yang 
Published: August 2015

Purpose– The purpose of this paper is to investigate the mediating effects of work-home interference (WHI) on the relationships between work demand, work attitudes, and job performance, with a focus on the moderating effect of Chinese work values (CWV).Design/methodology/approach– A self-administered survey method was used. The sample comprised 1,032 employees from Mainland China, Hong Kong, and Taiwan. The moderated mediation framework was used to test the proposed model.Findings– The results showed that WHI mediated the relationships among work demand, job satisfaction, and affective organizational commitment (AOC), but did not mediate the relationship between work demand and job performance. CWV moderated the mediated relationships and exacerbated the mediation effects of WHI on the relationships between work demand and job satisfaction and AOC.Research limitations/implications– The use of a cross-sectional design prevented the drawing of causal inference. With the exception of job performance, the self-reported measures are all subject to the problem of common method bias.Practical implications– Organizations in Greater China could implement stress management programs to reduce the negative effects of work demands. HR practitioners and managers should understand what values their employees hold to provide the proper interventions for them.Originality/value– By integrating both the mediator (WHI) and a moderator (CWV), this study investigated how CWV, an individual-level cultural value, affects the influences of WHI. The results highlight the importance of incorporating culturally specific value constructs when examining the underlying mechanisms of WHI.
Diagnosis and economic impact of operational variability – a case from the chemical forest industry
Authors: Rantamäki Jukka Mikael , Saarela Olli 
Published: August 2015

Purpose
– This paper deals with the identification and diagnosis of operational variability in chemical processes, which is a common problem in mills but little explored in literature. The Cross-Industry Standard Process for Data Mining (CRISP-DM) is a widely used approach in problem solving. The purpose of this paper is to: first, contribute to the body of knowledge on applying CRISP-DM in a pulp mill production process and the special issues that need to be considered in this context. Exact amounts of a cost increase due to variation in pulp production have not been reported previously. Second, to quantify the cost of variation.

Design/methodology/approach
– In the case studied, the variation in a pulp mill batch cooking process had increased. In order to identify the causes of variation, CRISP-DM was applied.

Findings
– The cycle of variation was identified and found to be related to the batch cooking process cycle time. By using information from this analysis it was possible to detect otherwise unobserved defective steam nozzles. The defective equipment was repaired and improved. Further improvement was achieved when the fouling of a heat exchanger was found by analysis to be the root cause of long-term variability parameters. By applying CRISP-DM, equipment defects and fouling were identified as the root causes of the higher manufacturing costs due to increased variation were detected and estimated. The Taguchi loss function is a possible tool for estimating the cost of variation in pulp manufacturing.

Originality/value
– This paper provides new knowledge in the context of implementing CRISP-DM and the Taguchi loss function in the pulp and paper manufacturing process.

Authors: Zhu Wei , Li Chen-yu , Xiao Xiao-yan , Xu Wen-bin 
Published: August 2015

Purpose
– The purpose of this paper is to develop an effective treatment to analyze and diagnose urban rail transit (URT) vehicle maintenance strategy.

Design/methodology/approach
– In this paper, the technique of Failure Mode and Effects Analysis (FMEA) is introduced into the examination of URT trains, first. Then the method of fuzzy-set-based assessment for FMEA is presented, which is the quantitative tool of Fuzzy-Set-based treatment for FMEA in analysis and diagnoses to URT maintenance strategy. Moreover, recommendations for further improvement of the proposed approach are also provided. Initial application into the vehicle maintenance of Shanghai URT System shows, that the proposed approach has a good performance and consequently is worth further development.

Findings
– The paper presents a FMEA and fuzzy-set-based theoretical approach for analyzing and diagnosing current methods in URT vehicle maintenance strategy.

Practical implications
– With rapid development of URT systems in the world especially in those highly populated areas, much more attentions are turning to researches on URT maintenance, nevertheless, few quantitative research achievement are mentioned or applied. This paper is a tentative attempt at introducing fuzzy-set theory into quantitative analysis and diagnoses of URT maintenance strategy.

Originality/value
– The study in this paper is helpful in theory and practice of URT maintenance and its methodology could be further applied into a broad family of facility group or system in other engineering fields.
A Markov decision process model case for optimal maintenance of serially dependent power system components
Authors: Bumblauskas Daniel 
Published: August 2015

Purpose
– Using a case study for electrical power equipment, the purpose of this paper is to investigate the importance of dependence between series-connected system components in maintenance decisions.

Design/methodology/approach
– A continuous-time Markov decision model is formulated to find a minimum cost maintenance policy for a circuit breaker as an independent component while considering a downstream transformer as a dependent component. Maintenance of the dependent component is included implicitly in terms of the costs associated with certain state-action pairs. For policy and cost comparisons, a separate model is also formulated that considers only the circuit breaker as the independent component. After uniformizing the continuous-time models to discrete time, standard methods are used to solve for the average-cost-optimal policies of each model.

Findings
– The optimal maintenance policy and its cost differ significantly depending on whether or not the dependent component is considered.

Research limitations/implications
– Data used are from manufacturer databases; additional model validation could be conducted if applied to an electric utility asset fleet within their generation, transmission, and/or distribution system. This model and methodology are already being applied in other contexts such as industrial machinery and equipment, jet engines, amusement park rides, etc.

Practical implications
– The outcome of this model can be utilized by asset and operations managers to make maintenance decisions based on prediction rather than more traditional time- or condition-based maintenance methodologies. This model is being developed for use as a module in a larger maintenance information system, specifically linking condition monitor data from the field to a predictive maintenance model. Similar methods are being applied to other applications outside the electrical equipment case detailed herein.

Originality/value
– This model provides a structured approach for managers to decide how to best allocate their resources across a network of inter-connected equipment. Work in this area has not fully considered the importance of dependency on systems maintenance, particularly in applications with highly variable repair and replacement costs.
Oxidative stress is related to both melanin‐ and carotenoid‐based ornaments in the common yellowthroat
Authors: Henschen Amberleigh E. , Whittingham Linda A. , Dunn Peter O. 
Published: August 2015

Summary

Male ornaments are hypothesized to signal the ability of males to produce an effective immune response without extensive oxidative stress and damage to DNA.

We examined this hypothesis in male common yellowthroats (Geothlypis trichas), which have two ornaments, a black (eumelanin‐based) facial mask and a yellow (carotenoid‐based) bib. In our study population, only the black mask is sexually selected.

As predicted by the oxidative stress hypothesis, males with larger black masks were more resistant to oxidative stress, as measured by an in vitro assay of the resistance of erythrocytes to haemolysis by free radicals. Furthermore, males with larger masks also tended to have lower levels of glutathione, which was predicted because glutathione inhibits eumelanin production. In contrast, mask size was not related to absolute levels of oxidative stress measured in the plasma.

Although the yellow bib is not under sexual selection in our population, males with larger bibs and feathers with greater carotenoid chroma had lower levels of oxidative stress.

The oxidative stress hypothesis was first proposed for carotenoid‐based ornaments. However, our results suggest that, even in the same individuals, carotenoid and eumelanin‐based plumage ornaments may both signal the ability of males to resist or manage oxidative stress.

SummaryModulation of the autonomic nervous system on heart rate can be compromised in chronic kidney disease and may result in changes in the frequency and duration of the cardiac cycle. The aim of this study was to evaluate autonomic modulation in active and sedentary renal transplant recipients. Twenty renal‐transplanted individuals were analyzed at the Centro de Prevenção de Doenças Renais (Kidney Disease Education Centre), in the academic hospital of Universidade Federal do Maranhão, and were divided into the active group (AG) and the sedentary group (SG). The AG comprised of six men and four women (age 43.10 ± 13.02) and was in regular concurrent training intervention for 8 weeks, while the SG was composed of three men and seven women (age 36.8 ± 9.26). Analysis of heart rate (HR) variability in time and frequency domain demonstrated that HR mean values in the SG and AG were 787.32 ± 79.60 and 870 ± 106.66 ms, respectively. Differences were observed in the time domain and frequency domain. The total index of low frequency and high frequency showed no differences between the SG and AG. Biochemical variables presented significantly lower levels after 8 weeks of training. Higher heart rate variability in the time domain and greater vagal modulation was observed in the AG. The AG ad greater vagal modulation when compared to the SG, with removal of the sympathetic and increased parasympathetic in the behaviour was confirmed by sympatho‐vagal balance. The AG also presented significant improvements in the frequency domain.
Spatio‐temporal elements of articulation work in the achievement of repeat prescribing safety in UK general practice
Authors: Grant Suzanne , Mesman Jessica , Guthrie Bruce 
Published: August 2015

AbstractPrescribing is the most common healthcare intervention, and is both beneficial and risky. An important source of risk in UK general practice is the management of ‘repeat prescriptions’, which are typically requested from and issued by non‐clinically trained reception staff with only intermittent reauthorisation by a clinical prescriber. This paper ethnographically examines the formal and informal work employed by GPs and receptionists to safely conduct repeat prescribing work in primary care using Strauss's (1985, 1988, 1993) concept of ‘articulation work’ across eight UK general practices. The analytical lens of articulation work provided an investigative framing to contextually map the informal, invisible resources of resilience and strength employed by practice team members in the achievement of repeat prescribing safety, where risk and vulnerability were continually relocated across space and time. In particular, the paper makes visible the micro‐level competencies and collaborative practices that were routinely employed by both GPs and receptionists across different socio‐cultural contexts, with informal, cross‐hierarchical communication usually considered more effective than the formal structures of communication that existed (e.g. protocols). While GPs held formal prescribing authority, this paper also examines the key role of receptionists in both the initiation and safe coordination of the repeat prescribing routine.

Published: August 2015

AbstractAimThe 40‐Something Randomised Controlled Trial (RCT) aimed to determine if a 12‐month health professional‐led intervention could improve dietary intake and increase physical activity for weight gain prevention in non‐obese premenopausal women.MethodsFifty‐four women were randomised to a motivational interviewing intervention (MI) (n = 28; five health professional consultations) or a self‐directed intervention (SDI; n = 26; written advice). Weight control behaviours including dietary intake (four‐day weighed food record) and physical activity (pedometer steps; minutes spent in light, moderate and vigorous activity; sitting time) were measured at baseline, and at 3 and 12 months. Participants completed a questionnaire containing demographic questions,ShortForm 36 and theInternationalPhysicalActivityQuestionnaire at baseline and 12 months. Linear mixed model analyses adjusting for baseline and 3‐month behaviour, covariates and interactions were used to test for between‐group differences.ResultsAt 12 months, theMIgroup had diets significantly more nutrient dense in iron (P= 0.01) and potassium (P= 0.04), and consumed more fruits (P= 0.02) than theSDIwomen. Women who achieved their weight control goals consumed significantly more daily fruit servings (+0.76 servings/day,P= 0.02) and less meat/meat alternatives (−0.34 servings/day,P< 0.01) than women who did not achieve weight control. The lack of changes in physical activity indicates that more emphasis may need to be placed on promoting physical activity.ConclusionsThe findings demonstrated the effectiveness of the 40‐SomethingRCTin improving iron and potassium nutrient density and fruit servings per day in women soon to commence menopause.
Education for Sustainable Development and International Student Assessments: Governing Education in Times of Climate Change
Authors: Sinnes Astrid T. , Eriksen Christoffer C. 
Published: August 2015

AbstractAt the end of the UN's Decade of Education for Sustainable Development there are few, if any, indications of comprehensive educational reforms meeting the challenges of sustainable development. Rather, a central aim for current educational reforms appears to be improvement of student performance on national and international educational assessments, such as the Organization for Economic Cooperation and Development (OECD)'s Programme for International Student Assessments (PISA). Against this background, this article explores the relationship between the UN's measures to promote education for sustainable development (ESD) and the OECD's measures to assist the development of education policy through PISA. The article finds that there are asymmetries in the ways these two different measures shape education systems. Moreover, the article also finds tensions between the educational practices associated with ESD, and those associated with ambitions to improve scores on PISA and other tests.

Authors: Choo Esther K. , Garro Aris C. , Ranney Megan L. , Meisel Zachary F. , Morrow Guthrie Kate 
Published: August 2015

AbstractQualitative methods are increasingly being used in emergency care research. Rigorous qualitative methods can play a critical role in advancing the emergency care research agenda by allowing investigators to generate hypotheses, gain an in‐depth understanding of health problems or specific populations, create expert consensus, and develop new intervention and dissemination strategies. This article, Part I of a two‐article series, provides an introduction to general principles of applied qualitative health research and examples of its common use in emergency care research, describing study designs and data collection methods most relevant to our field, including observation, individual interviews, and focus groups. In Part II of this series, we will outline the specific steps necessary to conduct a valid and reliable qualitative research project, with a focus on interview‐based studies. These elements include building the research team, preparing data collection guides, defining and obtaining an adequate sample, collecting and organizing qualitative data, and coding and analyzing the data. We also discuss potential ethical considerations unique to qualitative research as it relates to emergency care research.
Redefining the Converted Jewish Self: Race, Religion, and Israel's Bene Menashe
Authors: Egorova Yulia 
Published: August 2015

ABSTRACTThe Bene Menashe stem from a number of Christian groups of the Indo‐Burmese borderland, some of whom back in the 1950s declared their descent from the Lost Tribes of Israel. In this article, I will use the example of the Bene Menashe migration to Israel to cast analytical light on different ways in which race and religion co‐constitute each other in processes of transnational migration. To do so, I will focus on one specific aspect of the Bene Menashe migration—the way the community has to construct and enact their religious affiliation to be able to become Israeli citizens and to be considered part of the Jewish people by their “hosts.” I argue that, in the case of the Bene Menashe, race and religion co‐produce each other in ways that reinforce racialized understandings of Judaism and Jewishness, and I suggest that what accounts for this phenomenon is that the opportunities that the Bene Menashe immigrants had in defining their religiosity in Israel were limited by the conditions of their migration, which developed against the backdrop of multiple colonial contexts.
