Influence of learning and service innovation on performance
Authors: Milbratz Thaise Caroline , Gomes Giancarlo , De Montreuil Carmona Linda Jessica 
Published: January 2020

Purpose
This paper aims to analyze the influence of organizational learning (OL) and service innovation (SI) on organizational performance of knowledge-intensive business services (KIBS) and examine the mediating role of SI.

Design/methodology/approach
Hypotheses were tested using the theoretical OL model of knowledge acquisition, distribution, interpretation and organizational memory (Huber, 1991; Lopez, Peon, & Ordas, 2005; Jiménez-Jiménez & Sanz-Valle, 2011), using structural equation modeling partial least squares analysis of a survey data set of Brazilian architectural firms.

Findings
Findings suggest that OL is significantly linked to SI and so is SI to organizational performance. However, neither the direct relationship between OL and organizational performance could be verified, nor the mediating effect of SI.

Practical implications
These results can offer KIBS managers insights that suggest that OL alone does not guarantee a significant impact in organizational performance, but it is a starting point for achieving SIs, that lead to performance improvement and competitive advantages.

Originality/value
This paper contributes to the knowledge production in the following ways: to the understanding of the relationship between OL and SI and its effect on organizational performance, traditionally overlooked in the literature; to the study of SIs, considering the importance of the service sector; and to the study of innovation processes in architectural firms, a sector traditionally understudied, because of the focus on large construction firms.
Determinants of online purchase intention: a PLS-SEM approach: evidence from Indonesia
Authors: Dewi Citra Kusuma , Mohaidin Zurina , Murshid Mohsen Ali 
Published: January 2020

Purpose
The purpose of this paper is to identify the factors affecting consumers' online purchase intention and to explore whether there was any significant difference between the path coefficients for males and females.

Design/methodology/approach
Data were collected by distributing questionnaires to 668 Indonesian consumers who were actively using the internet. The data were analyzed using partial least squares structural equation modeling (PLS-SEM) and multi-group analysis (MGA) in SmartPLS 3.0 software.

Findings
Results show that performance expectancy, effort expectancy and personal innovativeness are three influential factors and have a higher path coefficient in both the male and female groups. Anxiety shows a negative and significant relationship with online purchase intention for female consumers than for male consumers. Furthermore, the results of MGA analysis indicate that most factor coefficients in the determinants of online purchase intentions are not significantly different between males and females.

Practical implications
These results help the web retailers to consider the important factors in their strategies when they make strategic decisions as key factors affecting online buying intention. Besides this, the strong relationship between anxiety and intention for females has important implications for managers and designers should pay attention to this factor when designing the content on their business website.

Originality/value
Even though several marketing scholars discuss the factors influencing online shopping behavior, a few studies have shown the role of anxiety and personal innovativeness and their effect on online purchasing that fitted as supplements into the Unified Theory of Acceptance and Use of Technology (UTAUT). In addition, so far, no studies have effectively made a comparative analysis across gender, i.e. are personal and UTAUT factors in the determinants of online purchase intention significantly different across gender?
Role conflict and work-life-family (WLF) demands: a perspective of Malaysian family business
Authors: Latip Hamrila Abd , Rahaman M. Monzer , Ayupp Kartinah , Lau Evan 
Published: January 2020

Purpose
The purpose of this study is to analyze the relationship between work-life-family (WLF) demands and job satisfaction in family businesses.

Design/methodology/approach
Data were collected from 220, who involve in the family business sector in Malaysia. In this study, the major demands in individuals are classified into three categories of WLF. The work component was measured in terms of standard working hours, work pressure and conditions, co-worker relationships and promotional opportunities. The life component was represented by living standards, level of self-motivation fulfillment, achievement of individual targets, self-compassion, self-care and health and community development. The family component represented another segmentation of responsibility and demands for specific role, which relates to family tasks, collective/familiness targets, family involvement and mutual understanding.

Findings
The empirical results indicated that work-related demands determine entrepreneurs’ job satisfaction, then followed by family-related and life-related (personal) demands. As this study was confined to the micro businesses under the family business sector, this provides valuable findings by uncovering the differences among the antecedents because of the reasoning of work culture and business management practices. It is argued that the role conflicts are related to job satisfaction, individual happiness and family contentment.

Originality/value
It expands the typology and fostering sustainable entrepreneurial development. Insights gained could facilitate business strategies and effective human resource policies particularly among the family businesses in Malaysia.
More can be better: operating multiple business models in a corporate portfolio
Authors: Bosbach Kirstin Eva , Brillinger Anne-Sophie , Schäfer Björn 
Published: January 2020

Purpose
Established firms are increasingly under pressure to develop new business models (BM) in a continuous manner to cope with competitive constraints and changing market requirements. Business model innovation (BMI) is widely accepted as a viable means to stay ahead of competition. Yet, firms struggle with successful BMI. The barriers to BMI is a widely discussed topic in academia and practice but with little reference to the barriers a firm is confronted with when operating multiple BMs in a corporate portfolio.

Design/methodology/approach
This paper investigates the implications for a firm operating a multitude of BMs concurrently. By combining the results of a literature analysis and 15 expert interviews from the fields of corporate strategy, business modelling and consulting, this paper presents and discusses the opportunities and challenges related to BM diversification.

Findings
The findings show that a strategic BM portfolio can be installed for enhanced value creation. However, managing multiple BMs and finding the right balance between existing and new business pose a major challenge for many established firms. With these results, the paper contributes to the existing literature in the fields of BMI and BM portfolio management. The findings clearly show the emerging importance of a strategic corporate BM portfolio for both research and practice and may provide an impetus for management discussions involving strategic BM portfolio decisions.

Originality/value
By building on and adding to existing literature and discussing existing works, this paper aims to giving a structured and comprehensive overview of enhancing and impeding factors on value creation when operating multiple BMs in a corporate portfolio.
Stochastic p-robust DEA efficiency scores approach to banking sector
Authors: Shakouri Rita , Salahi Maziar , Kordrostami Sohrab 
Published: January 2020

Purpose
The purpose of this paper is to present a stochastic p-robust data envelopment analysis (DEA) model for decision-making units (DMUs) efficiency estimation under uncertainty. The main contribution of this paper consists of the development of a more robust system for the estimation of efficiency in situations of inputs uncertainty. The proposed model is used for the efficiency measurement of a commercial Iranian bank.

Design/methodology/approach
This paper has been arranged to launch along the following steps: the classical Charnes, Cooper, and Rhodes (CCR) DEA model was briefly reviewed. After that, the p-robust DEA model is introduced and then calculated the priority weights of each scenario for CCR DEA output oriented method. To compute the priority weights of criteria in discrete scenarios, the analytical hierarchy analysis process (AHP) is used. To tackle the uncertainty of experts’ opinion, a synthetic technique is applied based on both robust and stochastic optimizations. In the sequel, stochastic p-robust models are proposed for the estimation of efficiency, with particular attention being paid to DEA models.

Findings
The proposed method provides a more encompassing measure of efficiency in the presence of synthetic uncertainty approach. According to the results, the expected score, relative regret score and stochastic P-robust score for DMUs are obtained. The applicability of the extended model is illustrated in the context of the analysis of an Iranian commercial bank performance. Also, it is shown that the stochastic p-robust DEA model is a proper generalization of traditional DEA and gained a desired robustness level. In fact, the maximum possible efficiency score of a DMU with overall permissible uncertainties is obtained, and the minimal amount of uncertainty level under the stochastic p-robustness measure that is required to achieve this efficiency score. Finally, by an example, it is shown that the objective values of the input and output models are not inverse of each other as in classical DEA models.

Originality/value
This research showed that the enormous decrease in maximum possible regret makes only a small addition in the expected efficiency. In other words, improvements in regret can somewhat affect the expected efficiency. The superior issue this kind of modeling is to permit a harmful effect to the objective to better hedge against the uncertain cases that are commonly ignored.
Transformation of professional identity: an exploration of psychologists and psychiatrists implementing Open Dialogue
Authors: Schubert Samantha , Rhodes Paul , Buus Niels 
Published: January 2020

This study explored how psychologists and psychiatrists working in Australian youth mental health services constructed their professional identity, and whether and how implementing Open Dialogue transformed this. Nine clinicians (psychologists, clinical psychologists and psychiatrists) were interviewed after completing Open Dialogue training. Interviews were subjected to discourse analysis. First, two general pre‐existing discursive professional identity positions were constructed: (i) psychiatrists rhetorically distancing themselves from the medical model as ‘fixers’ of mental illness; and (ii) psychologists and psychiatrists rhetorically embracing their personal identity. Second, participants’ responses about implementing Open Dialogue revealed opportunities and discomforts, including: (i) dialogical approaches offering psychiatrists an alternative identity to ‘fixers’; and (ii) dialogical approaches generating discomfort at the risk of exposing participants’ own vulnerability. Participants’ professional identities comprised contrasting positions.Practitioner points

Clinicians’ professional identities comprised contrasting positions

Clinicians constructed their professional identities by othering themselves from perceived dominant professional paradigms

Clinicians incorporated dialogical approaches into existing clinical work after being exposed to Open Dialogue

Clinicians identified Open Dialogue as offering opportunities to construct alternative professional identities

Clinicians appeared uncomfortable with dialogical approaches in situations of high risk within risk‐averse settings
The other between fear and desire – countertransference fantasy as a bridge between me and the other
Authors: Eulert‐Fuchs Daniela 
Published: January 2020

AbstractThis paper attempts to show how unrepresented rupture/injury of primary expectations of the early relationship is reactivated in the analytic process. This becomes perceptible especially as unconscious fear and a specific defence described as ‘living behind a glass‐wall’. The author, however, postulates the existence of an inherent dialogical‐dyadic principle in the psyche, which she calls archetypal hope, and shows how this principle may become active in the analytical space. These aspects of analytical treatments are sketched with two vignettes, in which unconscious processes of exchange cause the analyst to experience unrepresented states. The author describes how the analyst is gradually able to experience and understand this, and how this understanding finally – without first becoming explicit – becomes effective in the analytical space. Special attention is given to the analytic attitude. A readiness to accept and move into regression and a receptivity to attune to the early sensory experience of the analysand is regarded as essential. Through this the analyst gains access to the inner space of the analysand and, through bodily experience and pre‐symbolic processes, the unrepresented may thus become figurable. The reverie and countertransference fantasies are understood as a bridge: they connect the analytic pair. However, the reverie also creates the transition between that which was not – the absent representation – and that which wants to emerge. It thus bridges the personal unconscious (implicit expectation) and the archetypal (the archetypal hope). Through this, the space of hope may become a space of possibility, and help bridge the chasm between the experienced and the hoped‐for.
Opening the closed heart: affect‐focused clinical work with the victims of early trauma
Authors: Kalsched Donald E. 
Published: January 2020

AbstractThis paper begins with the understanding that early trauma leads to powerful dissociative defenses which injure the capacity to feel. It further explores ways to restore this capacity through body‐centred attention to affect‐in‐the‐moment in the psychoanalytic situation. Using the author’s personal experience while in analysis as well as a case of severe early trauma, he demonstrates the consciousness‐killing effect of primitive defenses and shows how body‐sensitive techniques hold the promise of restoring the patient’s sense of aliveness and hence, opening the unconscious to those affect‐images that are the building blocks of the human imagination. A final section focuses on the neglect of feeling in Jungian psychology and suggests that the “creation of consciousness” which Jung described as his personal myth, is quintessentially a process of emotional transformation – of bringing unconscious suffering into consciousness – as feelings.
Reaching out to big losers leads to sustained reductions in gambling over 1 year: a randomized controlled trial of brief motivational contact
Authors: Jonsson Jakob , Hodgins David C. , Munck Ingrid , Carlbring Per 
Published: January 2020

AbstractBackground and aimsA previous randomized controlled trial demonstrated that telephone‐ and letter‐based motivational interventions with high‐expenditure gamblers had significant short‐term positive effects on gambling and use of responsible gambling tools. This post‐trial follow‐up examined outcomes in gambling expenditure over 12 months.DesignObservational study following a three‐arm randomized controlled trial.SettingCustomers of Norsk Tipping (NT) gambling platforms, Norway.ParticipantsA total of 1003 statistical triplets from the top 0.5% of customers based upon annual expenditure, matched on sex, age and net losses. Mean age was 53.4 years; 19% were women, mean yearly loss for 2016 was 88 197 NoK.Interventions and comparatorFeedback intervention by telephone, letter or a no‐contact control condition.MeasurementsPrimary outcome measure was gambling theoretical loss, derived from the NT customer database. Secondary outcomes were responsible gambling customer actions and whether or not the participant was retained as an NT customer.FindingsPer‐protocol analyses of triplets who received the telephone call or letter as randomly assigned (n = 596) showed a positive and sustained effect over 12 months: the telephone group showed a 30% reduction in theoretical loss (d = 0.44) and the letter group 13% (d = 0.18), both outperforming the control group with a 7% reduction (d = 0.11). The telephone condition was superior to both the letter and control conditions in per‐protocol (P < 0.001) and to control condition in intention‐to‐treat analyses (ITT) (P < 0.001). Individuals in the telephone condition took more responsible gambling actions. The letter condition had better outcomes than the control in the ITT‐only analysis (P < 0.001). More than 93% were still customers a year after the intervention.ConclusionsPersonal contact with high‐expenditure gambling customers in Norway that provided individualized feedback on expenditures was associated with reduced theoretical losses and greater use of responsible gambling tools over a 12‐month period, compared with no contact. Telephone intervention with customers had a larger impact than a mailed letter.
Characterisation of alternative stable vegetation assemblages in a mesic savannah in Kenya
Authors: Kimeu John Mbaluka , Mwachala Geoffrey , Reichgelt Tammo , Muasya A. Muthama 
Published: January 2020

AbstractThe phenomenon of sharp boundaries between distinctive vegetation types occurring under the same climatic conditions has often been interpreted by plant ecologists to characterise alternative stable states (ASS). The phenomenon may be relevant in explaining two strikingly different vegetation formations (broad‐leaved nonspiny Combretum and fine‐leaved spiny Acacia) co‐occurring in mesic savannah of southeastern Kenya. We hypothesise that the two vegetation within southeastern Kenya ecosystems represent ASS whose transition may be a response to soil characteristics switch. To explore our hypothesis, we analysed empirical field data of woody species and soil characteristics from 57 plots that included 25 from Combretum and 32 from Acacia vegetation formations. We compared floristic composition and soil characteristics between the two systems and correlated edaphic statuses and vegetation states. We encountered 2,749 woody plant individuals, representing 115 species, 87 genera and 40 families. We found that the two vegetation had discrete woody species composition and soil characteristics, and also a significant species–edaphic association. The results are consistent with the ASS theory demonstrating that soil characteristics are among the important micro‐environmental filters driving and maintaining woody vegetation mosaics in the tropics. Importantly, understanding ASS has ramifications for sustainable utilisation of woody plant resources in East African savannahs.
Practices of Illegalisation
Authors: De Genova Nicholas , Roy Ananya 
Published: January 2020

AbstractThis article contributes to theorising the often unrecognised continuities between the illegalisation of migrant and refugee mobilities as an effect of lawmaking or other state practices of border policing and immigration law enforcement and the illegalisation of the rights, claims, and juridical status of minoritised citizens. Against a backdrop of resurgent right‐wing nationalisms, we pursue this transversal analysis of state practices of illegalisation to draw attention not only to labour subordination and disposability but also the more fundamental relationship between law and terror. The making of such regimes of citizenship takes place in obvious ways at the ostensible outer edges of nation‐state territories. They are also replicated in the various spatial arrangements that ensure racialised dispossession within global cities, cities that are better understood as reconfigurations of settler‐colonial cities. We argue that the study of practices of illegalisation allows critical poverty scholarship to better discern how sociopolitical categories and classifications that are central to wider processes of marginalisation and domination may arise or be reinforced as effects of the state’s legal productions of illegality.
A scoping review presenting a wide variety of research on paediatric and adolescent patients with Marfan syndrome
Authors: Lidal Ingeborg Beate , Bathen Trine , Johansen Heidi , Velvin Gry 
Published: January 2020

AbstractAimThe present study aimed to map and summarise the research on children, aged 0‐18 years, with Marfan syndrome, identify research gaps and point to research agendas.MethodsA scoping review was systematically performed by searching multiple databases from January 1996 to April 2019. Primary studies presenting results on at least six individuals aged 0‐18 years with Marfan syndrome, diagnosed according to the Ghent nosology, were selected.ResultsFrom 2341 de‐duplicated records, 92 papers were included, mapped and described. Their topics were diagnostics (12%), cardiovascular matters (50%), skeletal matters (22%), ocular matters (9%), other medical aspects (5%) and psychosocial perspectives (2%). Most studies were from Europe and North America and published between 1999 and 2019 in subject‐specific or paediatric journals, while a few were published in genetics journals. All studies had quantitative designs, and very few were multicentre studies. Each study had six to 608 subjects for a total of approximately 5809.ConclusionA wide range of research topics on adolescent and paediatric Marfan syndrome was found, but qualitative studies and a focus on psychosocial matters were lacking. Future investigations addressing noncardiovascular consequences and patient experiences are needed, as well as studies reaffirming or replicating existing intervention study results.
