Dynamics of a Form-Fitting Protein in a Nanopore: Avidin in ClyA
Authors: Lu Bo , Stokes Chris , Fahie Monifa , Chen Min , Golovchenko Jene A. , Hau Lene Vestergaard 
Published: November 2017

ABSTRACTWe probe the molecular dynamics of a protein, avidin, as it is captured and trapped in a nanopore, ClyA, with time-resolved single-molecule electrical conductance measurements, and we present a method for visualizing this process from the data. The case of avidin in ClyA has rich time-dependent conductance spectra of discrete levels that correlate with different configurations of the protein in the pore. One is very long-lasting, stable and noise-free, and portends the use of this system as a platform for more general studies of proteins and other molecules, where avidin acts as a shuttle that ferries analytes into the pore for probing. We demonstrate this by the sensitive detection of a biotin molecule attached to avidin captured by the pore. We also present an approach to determining the nanopore size based on a 3D printed model of the pore.
A structured method for innovating in entrepreneurship pedagogies
Authors: Balan Peter , Maritz Alex , McKinlay Matthew 
Published: November 2017

PurposeThe purpose of this paper is to describe a dynamic and continuous process for evaluating entrepreneurship pedagogies to implement continuous improvement of entrepreneurship education in order to achieve increased student engagement in face-to-face classes. Pedagogy is argued to be a significant contributor to entrepreneurship education programmes, consisting of dynamic activities and initiatives within the scope of defined entrepreneurship education ecosystems.Design/methodology/approachA “minute paper” was used as a quick and convenient method to obtain qualitative data on student perceptions of different pedagogies. The research adopted an action-research strategy where data were analysed using concept mapping to identify key themes that the educator can use to further develop or modify the pedagogy during course delivery.FindingsThe research identified student perceptions of the nature of engagement with pedagogies, and of possible improvements that were used by the educator to increase student engagement during course delivery. Different pedagogies were found to have varying outcomes on students’ engagement with entrepreneurship learning, and as such, contextual and spatial factors have to be taken into account when implementing new and/or adjusted pedagogies.Research limitations/implicationsRepeated application of the research method to different pedagogies was carried out in several deliveries of an undergraduate entrepreneurship foundation course in one university. As such, further research requires testing in various institutional and delivery contexts as well as comparisons of learning and other outcomes including entrepreneurial intentions between classes where particular pedagogies may or may not be used.Practical implicationsThe approach described is relatively straightforward to implement, with marginal resource and time. It provides rich data that gives insights into student perceptions of engagement with an individual pedagogy that the educator can use to modify to modify in order to increase student engagement.Originality/valueThe paper describes a practical method for educators to evaluate and develop optimal pedagogies for a particular class or group of students. This method can be applied to small as well as large class sizes, and data analysis can be carried out in real time to make improvements during course delivery. Although this method is described in the context of entrepreneurship education, it can be applied to other fields of instruction.
Mobile banking behavior and flow experience
Authors: Jamshidi Dariyoush , Keshavarz Yousef , Kazemi Fazlollah , Mohammadian Moghaddaseh 
Published: November 2017

Purpose
Mobile banking or m-banking enables consumers to carry out their banking affairs with the help of mobile devices. Mobile-user banking interactions in the context of technology services create opportunities for positive experiences that can nurture trust, foster brand equity and eventually lead to long-term relationship building. The purpose of this paper is to examine the concepts of m-banking customer flow experiences and their role in affecting customer intention in the continued use of m-banking.

Design/methodology/approach
To achieve this main objective, a research model was developed by taking theoretical backgrounds and specific characteristics of m-banking into consideration for testing. The study to test this model was carried out in Iran, a developing country in the Middle East.

Findings
Results of the PLS-SEM analysis of 927 bank customers showed that the flow experience is positively influenced by both hedonic and utilitarian features. While, flow experiences influence trust and brand equity, individual mobility has a stronger effect on the intention to continue the use of m-banking compared with trust, flow experience and brand equity.

Originality/value
The current research provides various useful insights into customer engagement for conducting banking tasks via mobile technologies. Managers and decision makers can take into account the following insights to enhance positive flow experiences and loyalty intention of customers toward m-banking.
Farm types and adoption of proven innovative practices in smallholder bean farming in Angonia district of Mozambique
Authors: Makate Clifton , Makate Marshall , Mango Nelson 
Published: November 2017

Purpose
Improving the adoption rates of proven innovative practices in bean farming and their impacts on livelihoods requires persistent promotion of practices, complemented by rigorous socioeconomic analysis that recognises the diversity of smallholder farmers. The purpose of this paper is to typify farm households in Angonia district of Mozambique, based on their socioeconomic characteristics prompting the adoption of proven innovative practices in bean production, management, and marketing.

Design/methodology/approach
The authors use a multivariate statistical analysis approach that combines principal component analysis, and cluster analysis to clearly identify five distinctive farm household types with respect to the adoption of proven innovative practices in smallholder bean farming using socio-economic factors.

Findings
The study findings show that various socioeconomic factors define clusters and can be associated with the adoption and use of innovative practices in smallholder bean farming. The five farm types identified are: female landowners with small farm sizes (29.52 per cent); educated farmers with access to credit (6.63 per cent); relatively rich male land owners with large farm sizes and low education (8.73 per cent); youthful, inexperienced and poor male farmers (6.33 per cent); and experienced female farmers with high labour endowments (8.43 per cent). The respective farm types seemed to have different patterns in the adoption of proven innovative practices in bean farming.

Originality/value
The authors recommend that policy makers promote strategies meant to raise adoption of innovative practices in bean production, management and marketing in Mozambique that takes into account household diversity. The farm types identified by this study can be a good starting point for guiding such future efforts.
Flexible flexibility! Food categorization flexibility and utilitarian preference
Authors: Ghosh Chowdhury Tilottama , Murshed Feisal , Khare Adwait 
Published: November 2017

Purpose
The purpose of this study is to propose that high categorization flexibility’s positive influence on hedonic or affect-laden choice is attenuated by conservation and nutrition mind-sets. Further, categorization flexibility can also promote utilitarian or cognitively superior preference and may have a role in steering customers toward healthier dietary choices.

Design/methodology/approach
Two experimental studies document that the pro-utilitarian impact of food categorization flexibility can be facilitated by priming conservation mind-set and nutrition mind-sets.

Findings
The results of this study show that conservation and nutrition mind-sets not only mitigate the earlier-demonstrated facilitative influence of food categorization flexibility on hedonic food preference, but also facilitate utilitarian food preference.

Originality/value
The current study provides the first evidence that food categorization flexibility can facilitate both hedonic and utilitarian preferences. The findings contribute to literature streams on categorization flexibility, resource-scarcity and hedonic versus utilitarian consumption. In addition, the findings offer specific prescriptions about encouraging customers to choose utilitarian and relatively more healthful food options, which in turn will improve the general welfare of the society.
Principals’ conceptions of their current power basis revealed through phenomenography
Authors: Özaslan Gökhan 
Published: November 2017

Purpose
The purpose of this paper is to describe the variations in the ways that principals conceptualize their basis of power in schools.

Design/methodology/approach
Phenomenography was used as the research method of this study. The interviewees consisted of 16 principals, eight from public schools and eight from private schools.

Findings
The analysis of the interviews revealed eight ways of understanding a principal’s power basis. These potential power bases were: teachers’ sense of reciprocity; teachers’ sense of responsibility; organizational rules and regulations; principals’ deep knowledge and experience; in-service training; principals’ reputation for being fair and impartial; teachers’ sense of identification with their principal; and principals’ control over teachers’ employment. Participants from public and private schools held generally similar conceptions. The conception of in-service training remained limited to private school principals. The power basis of principals’ control over teachers’ employment was not emphasized but could still be perceived as a conception in certain statements by participants.

Research limitations/implications
Coercive power and legitimate power of reciprocity need to be investigated more thoroughly in the field of educational administration.

Practical implications
There is an urgent need for training for principals to raise their awareness of the adverse effect that coercive power has on teachers.

Originality/value
This study is the first known to explore variations in the ways that principals conceptualize their power basis.
Risk in mental health: a review on and of the psychiatrist
Authors: Newton-Howes Giles 
Published: November 2017

Purpose
The purpose of this paper is to review the perceptions of risk from the viewpoint of the psychiatrist, in the context of the expectations of patients, staff and society.

Design/methodology/approach
The paper is a reflection on clinical practice and narrative review of the literature.

Findings
There are significant problems in the prediction of risk, to do with the difficulty in attempting to predict any low prevalence outcome. Additional complications relate to societal expectations and the legal frameworks within which mental health is practiced. The evidence related to poor outcomes, such as suicide is very complex, occasionally appears contradictory, and caution is required in application. The paradigm of recovery provides a way forward in the assessment and management of risk that moves away from any pretence of future prediction and aims to engage with service users and their families in a supportive and complimentary way.

Practical implications
Use of a recovery framework, with a focus on need, as opposed to risk, would appear to benefit patients, carers and those delivering service.

Originality/value
This viewpoint enables a broader gestalt of the literature in the context of day-to-day clinical practice. This prevents the limitation of only examining the (largely) epidemiological literature, or just commenting on one clinician’s practice. It provides for a conceptualization of a way to move forward in the consideration of risk.
Questions for conversation theory or conversation theory in one hour
Authors: Pangaro Paul 
Published: November 2017

Purpose
In an ideal situation, the author would like to answer each of the following questions: What is Conversation? What is Theory? What is Conversation Theory, anyhow? How did it arise? Who participated? How is it a theory? Where did it end up? Is it interesting? How might it be useful? Where has it been applied? Why should you care? What does it offer the practice of education? Of design? Of ethics? Where is it headed? (Sorry, steering joke, since Conversation Theory is situated in cybernetics, the art of steering). The purpose of this paper is to answer as many of these questions as practical.

Design/methodology/approach
The seeds of Conversation Theory lie in Gordon Pask’s instincts and in his “making”. This paper begins by describing some of the machinery he constructed to explore human interaction. Next, a skeletal model of conversation is offered, and connections to Pask’s own diagrams are drawn. Complementary to these models of the structure of conversations are their consequences, which are described in broad terms rather than given in detail. Lastly, Pask’s approach to proposing a scientific theory, and his means of achieving it, are explained.

Originality/value
Conversation Theory is a thoroughly original body of work, unmatched by its range and specificity. It is little known and yet potentially profound, with a scope that has already influenced educational psychology, second-order cybernetics, knowledge modeling and software design. By describing its origins, models and implications, the author hopes its value can be extended to new generations and to new domains.
Contextual ambidexterity and innovation in healthcare in India: the role of HRM
Authors: Malik Ashish , Boyle Brendan , Mitchell Rebecca 
Published: November 2017

PurposeThe purpose of this paper is to examine innovation in the resource-constrained context of India’s healthcare industry. It is argued that the process of innovation in addressing healthcare management challenges in such a context occurs through organisational ambidexterity and that human resource management (HRM) plays an important role.Design/methodology/approachA qualitative research methodology is applied to explore the role of HR practices in facilitating contextual ambidexterity and subsequent innovations in healthcare in India. The unit of analysis is the “case” of healthcare providers in India and in-depth interview and documentary data in two case sites are analysed to reveal the role of HRM in facilitating contextual ambidexterity and innovation. Data analysis was undertaken first at a within-case and then at a cross-case analysis level using interpretive manual coding based on how the data explained the role of HRM in delivering innovative outcomes and supporting organisational ambidexterity.FindingsThe authors found evidence of the use of sets of high-involvement HRM practices for exploration of new ideas and efficiency-driven HRM practices for creating contextual ambidexterity in the case organisations. Further, managerial/leadership style was found to play an important role in creating cultures of trust, openness, risk-taking and employee empowerment, supported by an appropriate mix of intrinsic and extrinsic rewards. Finally, training was also reported as being central to creating an ambidextrous context for delivering on various innovations in these healthcare providers.Originality/valueThis study represents an exploration of innovation in the context of India’s healthcare sector through intersecting literatures of ambidexterity, innovation and HRM practices. In light of the emerging economy research context, an important empirical contribution is palpable. Moreover, through a study design which included collecting data from multiple informants on the role of human resources in facilitating innovative outcomes, the authors reveal the role of HR-related initiatives, beyond formal HR practices in creating contextual ambidexterity. This study also reveals the degree to which contextual idiosyncrasies enhance our understanding of the role of HR in facilitating innovation in emerging economies.
Relative complex permittivity and its dependence on frequency
Authors: Giannoukos Georgios , Min Mart , Rang Toomas 
Published: November 2017

Purpose
This paper aims to give a brief overview of dielectric properties, relative complex permittivity and its dependence on frequency. The significance of different approaches to complex permittivity is also discussed.

Design/methodology/approach
The different mechanisms of polarization are then presented. Dielectric measurements are given, and an RC parallel-equivalent circuit is used to simulate a parallel plate capacitor, and the way in which the impedance of the circuits is affected by frequency is illustrated in their respective diagrams. The way in which dielectric properties change with time is also discussed.

Findings
The goal of this paper is to give an overview of the characteristics of the dielectrics and how frequency affects the relative complex permittivity and to present different approaches to and equations for the relative complex permittivity, such as that of Debye, Cole–Cole, Cole–Davidson and Havriliak–Negami. In addition, three mechanisms of polarization, namely, electronic, atomic and bipolar, are presented. The most common dielectric characterization device, a capacitor with parallel plates between which the dielectric material under study is located, is also discussed. Ohmic and dielectric losses of a non-ideal capacitor are accounted for. Furthermore, this paper studies the equivalent circuits of a non-ideal parallel plate capacitor, those being a resistor and an ideal capacitor connected either in series or in parallel.

Originality/value
Finally, dielectric responses to both time and to stepwise excitation are given.

Successful treatment of Raynaud's phenomenon and digital ulcers in systemic sclerosis patients with botulinum toxin B injection: Assessment of peripheral vascular disorder by angiography and dermoscopic image of nail fold capillary
Authors: Motegi Sei‐ichiro , Sekiguchi Akiko , Saito Shintaro , Ishibuchi Hirohisa , Kishi Chikako , Yasuda Masahito , Ishikawa Osamu 
Published: November 2017

AbstractWe recently identified the efficacy and safety of a botulinum toxin (BTX)‐A/B in Raynaud's phenomenon (RP) and digital ulcers (DU) in Japanese patients with systemic sclerosis (SSc). Detailed assessments of peripheral vascular disorder using angiography and dermoscopic images of nail fold capillaries have not been performed previously. This study aimed to evaluate the effect of BTX‐B on SSc‐associated peripheral vascular disorder. Two SSc patients who suffered with RP and DU were treated with a BTX‐B injection, and thereafter the symptoms of RP were improved and DU healed in both patients. Furthermore, angiography showed an increased blood flow to the palm and fingers, and dermoscopic images of nail fold capillary changes showed improvement. These results suggest that a BTX‐B injection may increase peripheral blood flow and improve RP and DU in SSc patients.
Explaining right‐wing terrorism and violence in Western Europe: Grievances, opportunities and polarisation
Authors: RAVNDAL JACOB AASLAND 
Published: November 2017

AbstractWhat explains cross‐national variation of right‐wing terrorism and violence (RTV)? This question remains largely unanswered in existing research on the extreme right because (1) events data suitable for cross‐national comparisons have been lacking, and (2) existing analyses fail to capture RTV's causal complexity, which involve multiple causal paths (equifinality) comprising causal conditions that become sufficient for the outcome only in combination (conjunctural causation). To help fill these gaps, this article uses new events data in a qualitative comparative analysis (QCA) research design, aiming to explain variation in the extent of RTV in 18 West European countries between 1990 and 2015. In doing so, the article identifies two ‘causal recipes’ that consistently distinguish countries with extensive RTV experience from those with low or moderate RTV experience. The first (North European) recipe involves the combination of high immigration, low electoral support for anti‐immigration (radical right) parties, and extensive public repression of radical right actors and opinions. The second (South European) recipe involves the combination of socioeconomic hardship, authoritarian legacies, and extensive left‐wing terrorism and militancy. Notably, both recipes contain elements of ‘grievances’ and ‘opportunities’, suggesting that these two theories, which are conventionally seen as contrasting, may be more fruitfully seen as complementary. Furthermore, a highly polarised conflict between far right activists and their enemies represents a third necessary condition for extensive RTV to occur. The article concludes by highlighting the paradox that countermeasures intended to constrain radical right politics appear to fuel extreme right violence, while countermeasures that may constrain extreme right violence would imply an advancement of radical right politics.
Green Buildings in Commercial Mortgage‐Backed Securities: The Effects of LEED and Energy Star Certification on Default Risk and Loan Terms
Authors: An Xudong , Pivo Gary 
Published: November 2017

AbstractWe study the impact of green building on loans in the CMBS market. A hazard model shows green buildings carry 34% less default risk, all else equal. A matched‐sample analysis gives similar results. We attribute the effect to a loan‐to‐value channel, where risk is lowered by a green price premium. The benefit comes at least partly from the level of green achievement, not only the label itself. Loans on buildings that were green at loan origination have slightly better terms than loans on nongreen buildings. That difference is growing over time, but the effect is economically small compared to default risk.
