Agent based models to investigate cooperation between cancer cells
Authors: Xavier Joao B. , Chang William K. 
Published: November 2015

AbstractWe present a type of agent-based model that uses off-lattice spheres to represent individual cells in a solid tumor. The model calculates chemical gradients and determines the dynamics of the tumor as emergent properties of the interactions between the cells. As an example, we present an investigation of cooperation among cancer cells where cooperators secrete a growth factor that is costly to synthesize. Simulations reveal that cooperation is favored when cancer cells from the same lineage stay in close proximity. The result supports the hypothesis that kin selection, a theory that explains the evolution of cooperation in animals, also applies to cancers.
Psychological interventions for adults with autism spectrum disorders: a review
Authors: Spain Debbie , Harwood Laura , O'Neill Lucy 
Published: November 2015

Purpose
– Adults who have autism spectrum disorders (ASD) experience a range of core and co-morbid characteristics which impede daily functioning and quality of life. Children and adolescents with ASD derive clinically meaningful benefits from psychological interventions, including those designed to reduce socio-communication deficits and mental health conditions. Relatively little is known about the effectiveness of these interventions for the adult ASD population. The paper aims to discuss this issue.

Design/methodology/approach
– A selective search of English language, peer-reviewed publications was undertaken, in order to summarise the empirical data pertaining to psychological interventions for adults with high-functioning ASD (HF-ASD).

Findings
– Thus far, social skills interventions, cognitive behaviour therapy techniques, and mindfulness-based approaches have been researched most extensively. Interventions have primarily sought to: reduce the impact of core ASD characteristics; enhance skills; and improve co-morbid mental health symptoms. Methodological and clinical heterogeneity render it difficult to generalise study findings across population samples, but overall, interventions appear to be associated with reductions in co-morbid symptom severity, and improved functioning.

Research limitations/implications
– Further studies that seek to improve functioning, reduce co-morbid characteristics, and enhance the propensity for attaining and maintaining independence are now needed.

Practical implications
– Adaptations to standard treatment protocols are likely required in order to enhance engagement and optimise treatment gains.

Originality/value
– This is one of the first reviews to focus specifically on psychological interventions for adults with HF-ASD.
Autism spectrum disorder, attention-deficit hyperactivity disorder and offending
Authors: Sabet Jessica , Underwood Lisa , Chaplin Eddie , Hayward Hannah , McCarthy Jane 
Published: November 2015

Purpose
– A wealth of research on autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD) has led to increased understanding and identification of each of these developmental disorders. Existing literature has sparked controversial discussions regarding whether aspects of ASD and ADHD predispose individuals to criminality. The purpose of this paper is to explore the link between these conditions and offending.

Design/methodology/approach
– A review of the literature on ASD, ADHD and offending was undertaken. This paper looks at the particular focus of the literature on the involvement of individuals with ADHD and ASD within the criminal justice system.

Findings
– There is some evidence of a link between ADHD and criminality. However, the relationship between ASD and offending is a little more difficult to ascertain. Complicating this further is the relatively unexplored subject of comorbid ASD/ADHD and criminal behaviour. This paper found that additional cognitive deficits and conduct problems are associated with comorbid ASD/ADHD, highlighting the need for further research and development of interventions.

Originality/value
– This paper seeks to examine whether predictions can be made with regards to what offending behaviour may look like in an individual with comorbid ASD/ADHD. This paper reviews the literature on offending in relation to both disorders to examine whether predictions can be made with regards to what the offending behaviour of an individual with ASD and ADHD may look like.
The January effect anomaly: effect on the returns-earnings association
Authors: Easterday Kathryn E. 
Published: November 2015

Purpose
– The purpose of this paper is to examine the January effect, a well-documented capital markets pricing anomaly in which January return premiums are observed to be on average higher than in other months of the year. Extant literature focusses primarily on investor trading behaviors and incentives. This study is different in that it investigates the link between the unusually high returns characteristic of the January effect and accounting earnings, a popular measure that investors use to judge firm value.

Design/methodology/approach
– The empirical model used in this study is derived from the analytical framework of Ohlson (1995) and Feltham and Ohlson (1995), which explains returns as a function of current and future accounting earnings. Isolating firms that exhibit January effect return premiums from those that do not offers a deeper look at the characteristics of the anomaly. Regression analyses are carried out using a modified Fama-MacBeth (1973) methodology. Quarterly earnings and returns data are drawn from Compustat and CRSP.

Findings
– The main finding is that the association between January returns and first quarter earnings is unexpectedly and significantly negative, not positive as predicted by the model. Coefficient signs for the other three quarters behave as expected. Additional analyses highlight a difference in the returns-earnings association between firms affected by the anomaly and those that are not. Robustness checks indicate that the findings are not spurious.

Originality/value
– Rather than applying trading or multifactor economic models that rely on some level of market inefficiency or irrational investor behavior, this study uses an accounting valuation approach that relies on neither. The unexpected negative association between January effect returns and earnings suggests that other factor(s) besides earnings may play into valuation judgments for investors in such firms, and invites further research.
Antecedents to export information generation: a cross-national study
Authors: Souchon Anne L. , Dewsnap Belinda , Durden Geoffrey R. , Axinn Catherine N. , Holzmüller Hartmut H. 
Published: November 2015

Purpose
– The purpose of this paper is to examine the factors that enhance export decision-makers’ generation of export information, using a non-linear approach and a multi-country context, and so provide export decision-makers with empirically based guidelines on how to maximize their information acquisition efforts.

Design/methodology/approach
– A broad perspective on export information generation is adopted, including marketing research, export assistance, and market intelligence. The model of antecedents to information generation is tested in three studies (USA, Austria, New Zealand, respectively) using structural equation modeling techniques. Multigroup and hierarchical analysis is performed to assess cross-national invariance of relevant measures, and quadratic effects.

Findings
– The findings show that the predictors of export information generation vary across the three countries studied, and that many of the relationships are non-linear.

Research limitations/implications
– This study contributes to the export marketing literature by developing the understanding of how exporters can develop greater knowledge of information sources on which to build export decisions, and the conditions necessary for enhanced export information acquisition activity. The findings highlight that future research should consider non-linear relationships and the examination of the outcomes of export information generation in a cross-national setting.

Practical implications
– The study findings advocate that practitioners (exporters and advisers) tailor their export information generation efforts to the different country needs.

Originality/value
– This research responds to a call for more theoretically based studies on antecedents to export information generation, concurrent with the use of more robust statistical methods.
International brands in emerging markets: the myths of segmentation
Authors: Tanusondjaja Arry , Greenacre Luke , Banelis Melissa , Truong Oanh , Andrews Taylah 
Published: November 2015

Purpose
– International brands are expanding their business into emerging markets seeking new consumers for their products. Multiple research studies suggest that there are two key differentiators between developed and emerging markets that managers must take into account. These are that consumers differentiate between local and international brands, and that consumer segments differ between emerging and developed markets. This paper refutes these myths. The paper aims to discuss these issues.

Design/methodology/approach
– The authors examine large-scale data of purchase behaviour across seven countries and six product categories through telephone or online data collection. Surveys conducted in conjunction with research consulting projects form the basis of data collection, with samples skewing towards middle-income population from urban areas within the emerging markets. The different survey methods used support the empirical generalisability of the findings.

Findings
– The authors find that brand user profiles in emerging markets rarely differ between local and international brands across age, income and gender. Differences in segmentation are related to geography – which is likely a factor of infrastructure differences. When brand users are compared, their attitudes towards the brands are also very similar between local and international brands across several attitudinal measures: “high quality”, “value for money”, “meet/understand my needs”, “affordability” and “trustworthiness”.

Originality/value
– The research highlights that consumers in emerging markets need not be segmented based on their brand purchasing behaviour when it comes to local and international brands. This is in line with a growing body of literature in consumer segmentation and in contrast to a considerable amount of traditional literature on emerging markets.
Knowing me, knowing you: perspectives on awareness in autism
Authors: Yuill Nicola , Parsons Sarah , Good Judith , Brosnan Mark 
Published: November 2015

Purpose
– The purpose of this paper is to raise important questions from the different perspectives on autism research that arose from a seminar on autism and technology, held as part of an ESRC-funded series on innovative technologies for autism.

Design/methodology/approach
– The paper focuses on the roles of technology in understanding questions about different perspectives on autism: how do people on the spectrum see neurotypicals (people without autism) and vice versa?; how do the authors use eye gaze differently from each other?; how might technology influence what is looked at and how the authors measure this?; what differences might there be in how people use imitation of others?; and finally, how should the authors study and treat any differences?

Findings
– The authors synthesise common themes from invited talks and responses. The audience discussions highlighted the ways in which the authors take account of human variation, how the authors can understand the perspective of another, particularly across third-person and second-person approaches in research, and how researchers and stakeholders engage with each other.

Originality/value
– The authors argue that the question of perspectives is important for considering how people with autism and neurotypical people interact in everyday contexts, and how researchers frame their research questions and methods. The authors propose that stakeholders and researchers can fruitfully engage directly in discussions of research, in ways that benefit both research and practice.
TalkBox: a DIY communication board case study
Authors: Hamidi Foad , Baljko Melanie , Kunic Toni , Feraday Ray 
Published: November 2015

Purpose
– The purpose of this paper is to present TalkBox, an affordable and open-source communication board for users with communication or speech disorders. Making and tinkering methods are combined with community engagement and participatory design to create a democratic and accessible approach to assistive technology design.

Design/methodology/approach
– The authors employed a community-engaged participatory design methodology where we incorporated input from stakeholders into the design of the interface. Close collaboration with our community partner allowed us to make informed decisions on different aspects of the design from sourcing of the material to testing the prototype.

Findings
– Through describing TalkBox, the paper presents a concrete example of how assistive technology can be designed and deployed more democratically, how collaborations between academia and community partners can be established, and how the design reflects different aspects of the methodology used.

Originality/value
– This paper explores the question of how can open-source technology and making methods contribute to the development of more affordable and inclusive designs through a concrete example.
An error-correction modeling of US consumer spending: are there asymmetries?
Authors: Baghestani Hamid , Kherfi Samer 
Published: November 2015

Purpose
– The purpose of this paper is to investigate four possible asymmetries in US aggregate consumption and its major components (durables, non-durables, and services) for the period 1990-2013. Understanding the asymmetric behavior of the components is important since the impact of monetary policy on separate consumer spending categories may differ substantially.

Design/methodology/approach
– The authors first employ stationarity and cointegration tests to specify and estimate the long-run equilibrium relationship between consumer spending and such variables as disposable income, consumer sentiment, and the expected real interest rate. The authors then specify a structural error-correction model for each spending category to simultaneously investigate such possible asymmetries due to the ratchet effect, psychological negativity bias, interest rate effect, and varying degree of adjustment in eliminating disequilibrium defined as the gap between actual and desired spending.

Findings
– First, consumption and its major components all display asymmetric behavior consistent with psychological negativity bias. Second, consumer spending on durable goods also displays asymmetries consistent with both the ratchet effect and the interest rate effect. Third, non-durables respond asymmetrically to disequilibrium; consumers adjust (increase) spending on non-durables only when actual spending is below desired spending on non-durable goods. Fourth, services also respond asymmetrically to disequilibrium; consumers adjust (reduce) spending on services only when actual spending is above desired spending on services.

Originality/value
– This study provides new insight on the asymmetric behavior of consumer spending. The authors believe that the findings should help with macroeconomic policymaking when such indicators as income, consumer sentiment, and expected real interest rates display significant variations.
Limited higher order beliefs and the welfare effects of public information
Authors: Cornand Camille , Heinemann Frank 
Published: November 2015

Purpose
– In games with strategic complementarities, public information about the state of the world has a larger impact on equilibrium actions than private information of the same precision, because the former is more informative about the likely behavior of others. This may lead to welfare-reducing “overreactions” to public signals as shown by Morris and Shin (2002). Recent experiments on games with strategic complementarities show that subjects attach a lower weight to public signals than theoretically predicted. The purpose of this paper is to reconsider the welfare effects of public signals accounting for the weights observed in experiments.

Design/methodology/approach
– Aggregate behavior observed in experiments on games with strategic complementarities can be explained by a cognitive hierarchy model where subjects employ limited levels of reasoning. They respond in a rational way to the non-strategic part of a game and they account for other players responding rationally, but they neglect that other players also account for others’ rationality. This paper analyzes the welfare effects of public information under such limited levels of reasoning.

Findings
– In the model by Morris and Shin (2002) public information is always welfare improving if strategies are derived from such low reasoning levels. The optimal degree of publicity is decreasing in the levels of reasoning. For the observed average level of reasoning, full transparency is optimal, if public information is more precise than private information. If the policy maker has instruments that are perfect substitutes to private actions, the government should secretly respond to its information without disclosing or signaling it to the private sector independent of the degree of private agents’ rationality.

Originality/value
– This paper takes experimental evidence back to theory and shows that the main result obtained by the theory under rational behavior breaks down if theory accounts for the bounded rationality observed in experiments.

Bank lending channel in Zambia: empirical evidence from bank level data
Authors: Simpasa Anthony , Nandwa Boaz , Nabassaga Tiguéné 
Published: November 2015

Purpose– The purpose of this paper is to explore the effect of monetary policy on the lending behaviour of commercial banks in Zambia using bank-level data.Design/methodology/approach– Dynamic panel data econometric analysis is used to uncover the evidence of monetary transmission mechanism in Zambian banking industry. Other specifications are used as robustness checks.Findings– Contrary to received evidence, the authors find that the bank lending channel in Zambia operates mainly through large banks. The effect of monetary policy on medium-sized banks is moderate while it is virtually non-existent for smaller banks. Furthermore, the data does not show evidence of relationship lending for smaller banks.Originality/value– Overall, the findings of this investigation suggest that price signals, rather than quantity aggregates, matter the most in the transmission of monetary policy in Zambia. The results therefore lend support to the central bank’s recent shift in monetary policy framework from using monetary aggregates to interest rate targeting as a means to strengthen effectiveness of monetary policy.
Configurations of leadership practices in hospital units
Authors: Meier Ninna 
Published: November 2015

Purpose– The purpose of this paper is to explore how leadership is practiced across four different hospital units.Design/methodology/approach– The study is a comparative case study of four hospital units, based on detailed observations of the everyday work practices, interactions and interviews with ten interdisciplinary clinical managers.Findings– Comparing leadership as configurations of practices across four different clinical settings, the author shows how flexible and often shared leadership practices were embedded in and central to the core clinical work in all units studied here, especially in more unpredictable work settings. Practices of symbolic work and emotional support to staff were particularly important when patients were severely ill.Research limitations/implications– Based on a study conducted with qualitative methods, these results cannot be expected to apply in all clinical settings. Future research is invited to extend the findings presented here by exploring leadership practices from a micro-level perspective in additional health care contexts: particularly the embedded and emergent nature of such practices.Practical implications– This paper shows leadership practices to be primarily embedded in the clinical work and often shared across organizational or professional boundaries.Originality/value– This paper demonstrated how leadership practices are embedded in the everyday work in hospital units. Moreover, the analysis shows how configurations of leadership practices varied in four different clinical settings, thus contributing with contextual accounts of leadership as practice, and suggested “configurations of practice” as a way to carve out similarities and differences in leadership practices across settings.
New nurse transition: success through aligning multiple identities
Authors: Leong Yee Mun Jessica , Crossman Joanna 
Published: November 2015

Purpose– The purpose of this paper is to explore the perceptions of new nurses in Singapore of their experiences of role transition and to examine the implications for managers in terms of employee training, development and retention.Design/methodology/approach– This qualitative study was conducted using a constructivist grounded theory approach. In total 26 novice nurses and five preceptors (n=31) from five different hospitals participated in the study. Data were collected from semi-structured interviews and reflective journal entries and analysed using the constant comparative method.Findings– The findings revealed that novice nurses remained emotionally and physically challenged when experiencing role transition. Two major constructs appear to play an important part in the transition process; learning how to Fit in and aligning personal with professional and organisational identities. The findings highlight factors that facilitate or impede Fitting in and aligning these identities.Originality/value– Although the concept of Fitting in and its relation to the attrition of novice nurses has been explored in global studies, that relationship has not yet been theorised as the dynamic alignment of multiple identities. Also, whilst most research around Fitting in, identity and retention has been conducted in western countries, little is known about these issues and their interrelationship in the context of Singapore. The study should inform decision making by healthcare organisations, nurse managers and nursing training institutions with respect to improving the transition experience of novice nurses.
