Evaluation as key to describing the enacted object of learning
Authors: Pillay Vasen , Adler Jill 
Published: June 2015

Purpose– The purpose of this paper is to illustrate the methodology used by the authors to describe the enacted object of learning, a methodology where data production and analysis is rooted in a theorisation of pedagogy. The authors share how the authors used this methodological approach to provide a comprehensive description of the enacted object of learning and in so doing the authors hope to make a methodological contribution to the field of learning study. The lesson analysis foregrounds the importance of “evaluation” in pedagogic practice, and thus a key element of pedagogy. Tools from variation theory are incorporated into this broader approach that the authors suggest illuminates the enacted object of learning. The authors offer this approach as a methodological contribution to the development of research in and on learning study.Design/methodology/approach– A case study approach was adopted as the key research methodology in this study. The four teachers who participated in this study were purposively identified since in the first instance the design of the study warranted that the teachers who participated were teaching mathematics at grade 10. Second, the need to be purposive in the sampling strategy employed was based on issues around cost, logistics and convenience.Findings– While learning study foregrounds the importance of examining the constitution of the enacted object of learning, the contention is that it is through a focus on evaluation that the authors are able to fully describe what is constituted as mathematics with respect to the enacted object of learning. Analysis of evaluation thus adds to the description of the enacted object in critical ways.Originality/value– Within the domain of learning study, this paper provides a novel way of engaging with a lesson transcript in an attempt to fully describe what comes to be constituted as the enacted object of learning. This is achieved by combining the notion of evaluative events and authorisation on one hand and variation theory on the other.

Authors: Martin Daniel , Clerc-Georgy Anne 
Published: June 2015

Purpose– The purpose of this paper is to present a lesson study (LS) approach implemented as part of the initial training of primary school teachers in a course on the oversight and accompaniment of learning. This course aims to develop students’ ability to analyse their practice and to shift attention to pupils’ learning processes.Design/methodology/approach– Data were collected on the contribution of the LS system and interaction protocols used in class, according to students.Findings– Qualitative analysis of this data shows the role played by the use of theoretical concepts in the quality of their planning, the depth of their analysis and the quality of their work in class.Practical implications– This work opens avenues for teacher training, in particular in terms of encouraging students to use theoretical concepts to prepare, implement and analyse their teaching.Originality/value– This approach is of interest in that it examines the use of theoretical concepts in a study lesson system during initial teacher training.
French Didactique des Mathématiques and Lesson Study: a profitable dialogue?
Authors: Clivaz Stéphane 
Published: June 2015

Purpose
– The purpose of this paper is to present French Didactique des Mathématiques (DM) to the Lesson Study (LS) community.

Design/methodology/approach
– This theoretical paper presents the origins of DM in the Theory of Didactical Situations (TDS) by Brousseau. It elaborates about didactical engineering, fundamental situation and other fundamental concepts. It briefly presents other Didactique theories: the theory of conceptual fields, the anthropological theory of the didactic, the joint action theory in didactics and the double approach. It considers importance of the (TDS) and influences over teaching of mathematics. This paper finishes by highlighting the ways Didactique and LS could contribute to each other in a profitable dialogue.

Findings
– The paper contrasts DM with some LS main features. It highlights the parallels despite fundamental differences in the initial goals of the perspectives. It shows that these differences could lead to productive dialogue by producing more practice-oriented forms of didactical engineering for the first and making teachers’ principles for lessons more explicit for the latter.

Originality/value
– The paper presents a very quick overview of the parallels between DM and LS. Additionally, this paper gives many accessible references in English for the reader to explore Didactique further.
Responses to customized products: the consumers’ behavioral intentions
Authors: Jiang Pingjun , Balasubramanian Siva K , Lambert Zarrel V. 
Published: June 2015

Purpose
– The purpose of this paper is to make contributions toward new knowledge and understanding of how marketers can provide effective online customization experiences for customers. The practicality of online mass customization has received much attention as consumers perceive more value from customized products than from their standardized counterparts. Little research has been done to understand consumers’ behavioral intentions in response to these value additions. This study incorporates product information framing in developing and empirically testing a model of the relationship between online customization and price sensitivity, endowment addition and expected likelihood of product return.

Design/methodology/approach
– The relationship among the constructs specified in the model was tested using multiple group structural equation modeling analysis.

Findings
– The findings indicate that consumers perceived knowledge gain via customization process influences the utilitarian value, which directly impacts levels of likelihood of product return and price sensitivity. The process value, on the hedonic side, influences more on the endowment addition. Endowment addition is found to mediate the relationship between the hedonic benefits and the two utilitarian outcome variables: price sensitivity and likelihood of product return.

Originality/value
– Understanding the consequences of customization is particularly crucial for marketers. This research is the first to expand and further our knowledge of customization, particularly in relation to its outcomes of customers’ behavioral intentions.
Selected dimensions of service gender: a study of perceptions of Generation Y
Authors: Melancon Joanna Phillips , Forbes Lukas P. , Fugate Douglas 
Published: June 2015

Purpose
– This paper aims to investigate how changes in technology and gender roles have changed Generation Y’s (Gen Y) perception of the gender of services from previous studies. Although the past 20 years have seen substantial changes in service delivery methods in addition to changes in the traditional roles of gender and households, in many ways, businesses continue to deliver products and services to their customers using traditional marketing techniques.

Design/methodology/approach
– Survey data were collected using a sample of 190 responses.

Findings
– Results indicate that consumers will consistently identify services as having gender, that consumers will rate service gender consistent with the perceived typical consumer of a service and that consumers will rate service gender consistent with the gender of their front-line employee. Online/automated services are also gendered. High-contact services have stronger gender identity than low-contact services. Congruence of consumer and service gender is more important to men than women.

Practical implications
– This study suggests that managers must understand gender identity of their services as well as cues that suggest gender relating to consumers and front-line employees. Automated and online services also must be positioned to give correct gender cues, particularly to male markets.

Originality/value
– This is one of the few studies to explore the gender identity of services and the first study to consider service gender in approximately two decades. Additionally, it is the first study to explore gender in automated delivery/online services as well as high/low-contact services, and the first study to gauge service gender perceptions of Gen Y.
Service interactions and subjective well-being in later life
Authors: Plaud Cécile , Guillemot Samuel 
Published: June 2015

Purpose
– The purpose of this paper is to examines the positive and negative impact of service provider experiences on the process of identity adjustment and how they can lead to subjective well-being (SWB). Due to increased life expectancies, people are experiencing major life events during aging (e.g. death of a spouse, serious disease and major health problems), events that lead to identity redefinition.

Design/methodology/approach
– To gain more insight into this issue, a qualitative study was carried out that involved 37 in-depth interviews conducted with aging individuals who had experienced a major life event such as retirement and/or death of spouse. To apprehend the diversity of consumption situations, the authors investigated daily consumption, hedonic consumption and imposed services (e.g. health and funeral services) due to life events.

Findings
– The findings suggest that service providers influence consumer’s SWB as regards relationships, growth and purpose in life, mastery and independence and self-acceptance.

Originality/value
– The contribution indicates that services play a role in maintaining and/or creating SWB. By segmentation through social roles and facilitating access to services, providers must take into account the processes of normalcy and abandonment (déprise) among aging consumers in life transitions. They must also ensure that they support consumers with the lowest human capital (skills, level of education, income and social class).
The market performance indicator: a macro understanding of service provider switching
Authors: D'Alessandro Steven , Johnson Lester , Gray David M. , Carter Leanne 
Published: June 2015

Purpose
– The purpose of this paper is to adapt the market performance indicator (MPI), used by the European Commission to evaluate market conditions, over time, to show that the MPI explains actual switching behavior better than stated intent and satisfaction. While research on service provider switching has focused on the outcomes of service transactions and the benefits of switching, there is little research on how consumers view market conditions as being favorable or not for switching.

Design/methodology/approach
– The authors used a mixed methodology of focus groups and longitudinal survey research of cell phone consumers to evaluate the effect of the MPI on satisfaction, perceptions of value, switching intentions and behavior.

Findings
– The MPI was found to influence perceptions of satisfaction and value, and was found to contribute strongly to actual switching behavior. The results also showed that an improvement in the MPI or market conditions lead to a much greater relationship between it and actual switching behavior, suggesting that there may well be important threshold level, upon which greater switching behavior occurs.

Originality/value
– The MPI provides marketers and policy-makers with benchmarks to compare the consumer welfare of different markets in different countries. Switching studies with MPI figures can be more easily generalized to different contexts.
Mass collaborative knowledge management
Authors: Borjigen Chaolemen 
Published: June 2015

Purpose– The purpose of this paper is to reveal the underlying principles of knowledge processing in a new era of mass collaboration and provide an integrated guideline for organizational knowledge management (KM) based on identifying the gaps between the existing KM theories and emerging knowledge initiatives such as Web 2.0, Pro-Am, Crowdsourcing, as well as Open Innovation.Design/methodology/approach– This research mainly employs three types of research methodologies: Literature study was conducted to connect this study with conventional theories in KM and propose the main principles of Mass Collaborative Knowledge Management (MCKM). Object-oriented modeling was used for designing its interaction model. The case study method was employed to discuss the two typical practices carried out by Goldcorp Inc. as well as the Defence Advanced Research Projects Agency.Findings– This paper proposes the novel KM paradigm called MCKM and also provides its main principles and the interaction model. First, it identifies the gaps between emerging practices and existing KM theories. Second, it embraces the long tails into the scope of organizational KM and extends the scope of prevailing KM studies. Third, it falls back on Pro-Ams to save the costs of and to reduce the risk to organizational KM as well. Fourth, it highlights the advantages of opening organizational internal knowledge and transforms the core beliefs in conventional KM. Finally, it classifies organizational knowledge into two types, domain knowledge and non-domain knowledge, and provides some managing policies, respectively.Practical implications– Introducing MCKM into organizational KM will not only enhance the organizational knowledge creation and sharing, but also help an organization build its open knowledge ecosystem.Originality/value– This is a paper to introduce a new direction of KM studies, which guides an organization to build an open knowledge ecosystem by implementing mass collaborations and taking advantages of the complementary advantages of men and machines in knowledge processing.
The effect of network externality on mobile social network site continuance
Authors: Zhou Tao 
Published: June 2015

Purpose
– The purpose of this paper is to examine the effect of network externality on users’ continuance of mobile social network sites (SNS).

Design/methodology/approach
– Based on the 230 valid responses collected from a survey, structural equation modeling was employed to examine the research model.

Findings
– The results indicated that network externality, which includes referent network size and perceived complementarity, has a significant effect on perceived usefulness and flow. Privacy concern affects perceived usefulness, flow and privacy risk. These three factors determine continued use.

Originality/value
– Previous research has focussed on the effects of motivations such as perceived value on user adoption of SNS. The effect of network externality on user continuance has seldom been examined. This research tries to fill the gap.
Effect of anelastic patchy saturated sand layers on the reflection and transmission responses of a periodically layered medium
Authors: Dupuy Bastien , Stovas Alexey 
Published: June 2015

ABSTRACTBased on analytic relations, we compute the reflection and transmission responses of a periodically layered medium with a stack of elastic shales and partially saturated sands. The sand layers are considered anelastic (using patchy saturation theory) or elastic (with effective velocity). Using the patchy saturation theory, we introduce a velocity dispersion due to mesoscale attenuation in the sand layer. This intrinsic anelasticity is creating frequency dependence, which is added to the one coming from the layering (macroscale). We choose several configurations of the periodically layered medium to enhance more or less the effect of anelasticity. The worst case to see the effect of intrinsic anelasticity is obtained with low dispersion in the sand layer, strong contrast between shales and sands, and a low value of the net‐to‐gross ratio (sand proportion divided by the sand + shale proportion), whereas the best case is constituted by high dispersion, weak contrast, and high net‐to‐gross ratio. We then compare the results to show which dispersion effect is dominating in reflection and transmission responses. In frequency domain, the influence of the intrinsic anelasticity is not negligible compared with the layering effect. Even if the main resonance patterns are the same, the resonance peaks for anelastic cases are shifted towards high frequencies and have a slightly lower amplitude than for elastic cases. These observations are more emphasized when we combine all effects and when the net‐to‐gross ratio increases, whereas the differences between anelastic and elastic results are less affected by the level of intrinsic dispersion and by the contrast between the layers. In the time domain, the amplitude of the responses is significantly lower when we consider intrinsic anelastic layers. Even if the phase response has the same features for elastic and anelastic cases, the anelastic model responses are clearly more attenuated than the elastic ones. We conclude that the frequency dependence due to the layering is not always dominating the responses. The frequency dependence coming from intrinsic visco‐elastic phenomena affects the amplitude of the responses in the frequency and time domains. Considering intrinsic attenuation and velocity dispersion of some layers should be analyzed while looking at seismic and log data in thin layered reservoirs.
Risk and resilience: health inequalities, working conditions and sickness benefit arrangements: an analysis of the 2010 European Working Conditions survey
Authors: van der Wel Kjetil A. , Bambra Clare , Dragano Nico , Eikemo Terje A. , Lunau Thorsten 
Published: June 2015

AbstractIn this article we ask whether the level of sickness benefit provision protects the health of employees, particularly those who are most exposed to hazardous working conditions or who have a little education. The study uses the European Working Condition Survey that includes information on 20,626 individuals from 28 countries. Health was measured by self‐reported mental wellbeing and self‐rated general health. Country‐level sickness benefit provision was constructed using spending data from Eurostat. Group‐specific associations were fitted using cross‐level interaction terms between sickness benefit provision and physical and psychosocial working conditions respectively, as well as those with little education. The mental wellbeing of employees exposed to psychosocial job strain and physical hazards, or who had little education, was better in countries that offer more generous sickness benefit. These results were found in both men and women and were robust to the inclusion of GDP and country fixed effects. In the analyses of self‐reported general health, few group‐specific associations were found. This article concludes that generous sickness benefit provision may strengthen employee's resilience against mental health risks at work and risks associated with little education. Consequently, in countries with a generous provision of sickness benefit, social inequalities in mental health are smaller.
3D Food Printing: A Taste of the Future
Authors: Lin Clarice 
Published: June 2015

AbstractOne of the core competencies in the Institute of Food Technologists (IFT) education standards is for students to achieve competency in communication skills (that is, oral and written communication, listening, interviewing, and so on). According to the IFT guidelines, by the time students graduate, they should not only be able to search for and condense information, but also be able to “communicate technical information to a nontechnical audience.” The Education, Extension and Outreach Division of IFT sponsors a writing competition for undergraduate students to bring attention to and promote the development of communication skills. It has been shown that employees/entry‐level scientists who can communicate technical and nontechnical concepts succinctly will be in a better position to achieve management status after entering the work force. Monetary prizes are awarded to the authors of the top 3 papers. A revised version of the winning entry is published in the Journal of Food Science Education for dissemination to a worldwide audience.
A case of rhabdomyolysis associated with severe opioid withdrawal
Authors: Gangahar Deepali 
Published: June 2015

Background and ObjectiveWhile the risk of opioid overdose is widely accepted, the dangers of opioid withdrawal are far less clearly defined. The purpose of this publication is to provide evidence against the erroneous clinical dictum that opioid withdrawal is never life‐threatening.Methods and ResultsThis case report (N = 1) illustrates an unfortunate, common scenario of a man abusing prescription opioids and heroin. His attempt at self‐detoxification with buprenorphine–naloxone resulted in life‐threatening opioid withdrawal. A detailed account of each day of his withdrawal period was documented by patient and family report and review of all medical records. The patient was contacted three months after hospitalization to verify information and determine progress in treatment and abstinence from drugs and alcohol.Discussion and ConclusionA review of the literature was completed on severe cases of precipitated and spontaneous opioid withdrawal followed by a discussion of the significance as it relates to this case.Scientific SignificanceGiven the widespread use of prescription opioids and opioid maintenance treatment, physicians should be aware of the complications of acute opioid withdrawal and should be equipped to treat these complications.

Response-Adaptive Randomization for Multi-arm Clinical Trials Using the Forward Looking Gittins Index Rule
Authors: Villar Sofía S. , Wason James , Bowden Jack 
Published: June 2015

Summary
The Gittins index provides a well established, computationally attractive, optimal solution to a class of resource allocation problems known collectively as the multi-arm bandit problem. Its development was originally motivated by the problem of optimal patient allocation in multi-arm clinical trials. However, it has never been used in practice, possibly for the following reasons: (1) it is fully sequential, i.e., the endpoint must be observable soon after treating a patient, reducing the medical settings to which it is applicable; (2) it is completely deterministic and thus removes randomization from the trial, which would naturally protect against various sources of bias. We propose a novel implementation of the Gittins index rule that overcomes these difficulties, trading off a small deviation from optimality for a fully randomized, adaptive group allocation procedure which offers substantial improvements in terms of patient benefit, especially relevant for small populations. We report the operating characteristics of our approach compared to existing methods of adaptive randomization using a recently published trial as motivation.
Sample Elimination for Generating Poisson Disk Sample Sets
Authors: Yuksel Cem 
Published: June 2015

AbstractIn this paper we describe sample elimination for generating Poisson disk sample sets with a desired size. We introduce a greedy sample elimination algorithm that assigns a weight to each sample in a given set and eliminates the ones with greater weights in order to pick a subset of a desired size with Poisson disk property without having to specify a Poisson disk radius. This new algorithm is simple, computationally efficient, and it can work in any sampling domain, producing sample sets with more pronounced blue noise characteristics than dart throwing. Most importantly, it allows unbiased progressive (adaptive) sampling and it scales better to high dimensions than previous methods. However, it cannot guarantee maximal coverage. We provide a statistical analysis of our algorithm in 2D and higher dimensions as well as results from our tests with different example applications.
