Non-paradoxical evolutionary stability of the recombination initiation landscape in Saccharomycetes
Authors: Lam Isabel , Keeney Scott 
Published: July 2015

AbstractThe nonrandom distribution of meiotic recombination shapes heredity and genetic diversification. A widely held view is that individual hotspots — favored sites of recombination initiation — are always ephemeral because they evolve rapidly toward extinction. An alternative view, often ignored or dismissed as implausible, predicts conservation of the positions of hotspots if they are chromosomal features under selective constraint, such as gene promoters. Here we empirically test opposite predictions of these theories by comparing genome-wide maps of meiotic recombination initiation from widely divergent species in theSaccharomycesclade. We find that the frequent overlap of hotspots with promoters is true of the species tested and, consequently, hotspot positions are well conserved. Remarkably, however, the relative strength of individual hotspots is also highly conserved, as are larger-scale features of the distribution of recombination initiation. This stability, not predicted by prior models, suggests that the particular shape of the yeast recombination landscape is adaptive, and helps in understanding evolutionary dynamics of recombination in other species.
Portraiture and social understanding
Authors: Levin Brooke 
Published: July 2015

Purpose
– The purpose of this paper is to discuss the possible explanations for deficits in social understanding evident in individuals with autism spectrum disorder (ASD). A potential intervention technique is proposed that has not yet been examined in this population: viewing and drawing portraits. This portraiture-based intervention seeks to address some of the core issues set forth in each of the theories explaining impaired social functioning. Furthermore, this intervention is intended to specifically increase exposure to facial stimuli in a safe and controlled environment. Instructions about how to look closely at a social partner’s face and how to glean salient emotional information from the facial expression displayed can be developed through a focused exploration of drawing and viewing portraits. Current techniques such as eye tracking and fMRI are discussed in the context of this proposed intervention.

Design/methodology/approach
– This paper reviews existing research about ASD and seeks to present a new proposal for an intervention using portraiture. First the paper discusses existing interventions and reviews the current research about potential causes/areas of deficiency in individuals on the spectrum. This paper subsequently proposes a new type of intervention and discusses the reasons underpinning its potential success in the context of existing research.

Findings
– This was a proposed study so no empirical findings have been reported. However, observations of individuals on the spectrum engaging with artwork are discussed in this paper.

Originality/value
– No other research or study has been proposed in current literature relating specifically to the use of portraits (looking at and creating) to help individuals with ASD.
Developing business students’ employability skills through working in partnership with a local business to deliver an undergraduate mentoring programme
Authors: Spence Sue , Hyams-Ssekasi Denis 
Published: July 2015

Purpose– Working collaboratively with local business is vitally important in the delivery of higher education (HE) in further education (FE). The purpose of this paper is to explore an effective way of engaging local employers to enhance the employability skills of students through a closely monitored and supported mentoring relationship. The project was developed in order to address the employability needs of final year business students at a HE facility offered by a college situated in the North West of England.Design/methodology/approach– Qualitative data were collected through the use of reflective journals and a series of focus groups with mentors and mentees.Findings– Overall both mentors and mentees reported positive responses to the mentoring scheme. From the mentees point of view self-confidence, employability skills and networks were enhanced. Mentors reported satisfaction in contributing to the local community. Challenges were found in matching mentors with appropriate mentees. A perceived poor match negatively affected the relationship. Mentors reported that mentees lacked career direction and seemed to have limited understanding of what was expected in the mentoring process.Research limitations/implications– The scope of this study is one mentoring scheme in one institution and therefore has limited generalisability. However, there are implications for the development of further mentoring schemes in other institutions in the UK and beyond.Originality/value– This mentoring scheme was carried out in FE that offers HE courses in a northern town with above average levels of unemployment and with a diverse ethnic population. The scheme involves senior managers volunteering to support business undergraduates.
The analysis of lane detection algorithms using histogram shapes and Hough transform
Authors: Ketcham Mahasak , Ganokratanaa Thittaporn 
Published: July 2015

Purpose
– The purpose of this paper is to develop a lane detection analysis algorithm by Hough transform and histogram shapes, which can effectively detect the lane markers in various lane road conditions, in driving system for drivers.

Design/methodology/approach
– Step 1: receiving image: the developed system is able to acquire images from video files. Step 2: splitting image: the system analyzes the splitting process of video file. Step 3: cropping image: specifying the area of interest using crop tool. Step 4: image enhancement: the system conducts the frame to convert RGB color image into grayscale image. Step 5: converting grayscale image to binary image. Step 6: segmenting and removing objects: using the opening morphological operations. Step 7: defining the analyzed area within the image using the Hough transform. Step 8: computing Houghline transform: the system operates the defined segment to analyze the Houghline transform.

Findings
– This paper presents the useful solution for lane detection by analyzing histogram shapes and Hough transform algorithms through digital image processing. The method has tested on video sequences filmed by using a webcam camera to record the road as a video file in a form of avi. The experimental results show the combination of two algorithms to compare the similarities and differences between histogram and Hough transform algorithm for better lane detection results. The performance of the Hough transform is better than the histogram shapes.

Originality/value
– This paper proposed two algorithms by comparing the similarities and differences between histogram shapes and Hough transform algorithm. The concept of this paper is to analyze between algorithms, provide a process of lane detection and search for the algorithm that has the better lane detection results.

Authors: Barlas Panagiotis , Lanning Ivor , Heavey Cathal 
Published: July 2015

Purpose– Data science is the study of the generalizable extraction of knowledge from data. It includes a variety of components and develops on methods and concepts from many domains, containing mathematics, probability models, machine learning, statistical learning, computer programming, data engineering, pattern recognition and learning, visualization and data warehousing aiming to extract value from data. The purpose of this paper is to provide an overview of open source (OS) data science tools, proposing a classification scheme that can be used to study OS data science software.Design/methodology/approach– The proposed classification scheme is based on general characteristics, project activity, operational characteristics and data mining characteristics. The authors then use the proposed scheme to examine 70 identified Open Source Software. From this the authors provide insight about the current status of OS data science tools and reveal the state-of-the-art tools.Findings– The features of 70 OS tools are recorded based on the criteria of the four group characteristics, general characteristics, project activity, operational characteristics and data mining characteristics. Interesting results came from the analysis of these features and are recorded here.Originality/value– The contribution of this survey is development of a new classification scheme for examination and study of OS data science tools. In parallel, this study provides an overview of existing OS data science tools.
A description logic based approach to formalizing the information bearing capability of paths in ER schemata
Authors: Xu Kaibo , Feng Junkang , Crowe Malcolm , Liu Lin 
Published: July 2015

Purpose
– The purpose of this paper is to show how description logics (DLs) can be applied to formalizing the information bearing capability (IBC) of paths in entity-relationship (ER) schemata.

Design/methodology/approach
– The approach follows and extends the idea presented in Xu and Feng (2004), which applies DLs to classifying paths in an ER schema. To verify whether the information content of a data construct (e.g. a path) covers a semantic relation (which formulates a piece of information requirement), the principle of IBC under the source-bearer-receiver framework is presented. It is observed that the IBC principle can be formalized by constructing DL expressions and examining constructors (e.g. quantifiers).

Findings
– Description logic can be used as a tool to describe the meanings represented by paths in an ER schema and formalize their IBC. The criteria for identifying data construct distinguishability are also discovered by examining quantifiers in DL expressions of paths of an ER schema.

Originality/value
– This paper focuses on classifying paths in data schemas and verifying their formalized IBC by using DLs and the IBC principle. It is a new point of view for evaluation of data representation, which looks at the information borne by data but not data dependencies.
The role of customer relations for innovativeness and customer satisfaction
Authors: Bellingkrodt Silvia , Wallenburg Carl Marcus 
Published: July 2015

Purpose– The purpose of this paper is to provide insights into commonalities and differences of service innovation across industries. The compared sectors are logistics service providers and IT service providers (SPs).Design/methodology/approach– Data were collected from 778 SPs via an online survey. Structural equation modelling was used to analyse the empirical data.Findings– Both types of SPs benefit from close customer relations in terms of innovativeness and customer satisfaction. However, ITSPs rely more on a large number of customers to be innovative than logistics service providers (LSPs), further, LSPs can evoke a higher level of customer satisfaction when being innovative.Research limitations/implications– Empirical data were collected in a single country (Germany) and at one point in time. A confirmation of the results in different service settings is therefore encouraged.Practical implications– The results help managers with regard to their strategic decisions. The differentiating effects influencing innovativeness and customer satisfaction have been revealed.Originality/value– The research is extended by developing a model based on the knowledge of service innovation, social exchange theory and industry characteristics and by empirically testing this model.
Business dynamics of on-premise wine trade: cases from South Korea
Authors: Hwang Jeeah , Kunc Martin 
Published: July 2015

Purpose
– This paper aims to explore the dynamics and performance of on-premise wine trade business.

Design/methodology/approach
– The study involved in-depth interviews with six on-premise businesses in Seoul, South Korea. The data obtained were methodically analysed to understand the impact of different variables through a qualitative business dynamic model.

Findings
– Customer satisfaction and number of customers are key performance factors for on-premise wine trade business. Customer satisfaction is driven by servicescape, wine lists and front-line employees. However, the length of wine list impacts directly on inventory costs and staff knowledge, while the number of service staff in the business has a non-linear effect on profits, as service staff does not grow linearly with the number of customers.

Research limitations/implications
– One important limitation is that the business dynamics model, which is based on South Korean cases, used only owners/sommeliers’ perspectives but not consumers’ perspectives. There are two implications. First, in terms of on-premise wine trade, the alignment of servicespace, front-line employees, wine lists and pricing strategy is key to shape customers’ expectations and confirm the market positioning of the business. Second, for wineries, understanding the dynamics of on-premise wine trade can help them to find strategies to position their wines.

Originality/value
– The paper offers two contributions. Firstly, the paper provides the first exploratory study on the business dynamics of on-premise wine trade businesses, which complements existing wine-buying behaviour studies. Secondly, the study explores the on-trade channel in South Korea, providing insights into an important Asian market.
Addressing substance misuse in medium secure settings in the UK and Ireland – a survey of current practice
Authors: Sandbrook Jeremy , Clark Tom , Cocksedge Karen Amanda 
Published: July 2015

Purpose
– Rates of co-morbid substance misuse are high within forensic populations. Addressing these problems should be a priority as mental disorder with co-morbid substance misuse is associated with worse outcomes, including rates of re-offending and violence recidivism. A study undertaken in 2006 by the Royal College of Psychiatrists’ Research and Training Unit concluded that the provision of substance misuse treatments in medium-secure units (MSUs) at that time was inadequate. The purpose of this paper is to investigate how services may have developed since then to inform discussion over future development and best practice.

Design/methodology/approach
– A postal survey, supported by the Quality Network for Forensic Mental Health Services, was sent to 62 MSUs across the UK and Ireland. This questioned prevalence, interventions and staff training in substance misuse.

Findings
– In total, 41 units responded (66 per cent). The data suggest rates of substance misuse within MSUs have reduced and provision of treatment has increased in recent years. The majority of MSUs provide a variety of interventions to address substance misuse and are internally resourced, in tune with current national guidance. However, the data suggest many MSU staff are not receiving adequate training in substance misuse treatments and some MSUs do not appear to have a cohesive strategy that would be consistent with best practice.

Practical implications
– This study provides an up-to-date overview of the provision of treatment for substance misuse within MSUs.

Originality/value
– There is no other source for this information, which will provide an invaluable reference point for services seeking to develop or improve their clinical services.
Warm welcome or rude awakening?
Authors: Valk Reimara , Velde Mandy Van der , Engen Marloes Van , Szkudlarek Betina 
Published: July 2015

Purpose
– The purpose of this exploratory, empirical study is to gain insight into repatriation experiences and repatriate turnover intention of employees from India and The Netherlands who either were or had been on international assignments in the respective countries.

Design/methodology/approach
– Interviews were conducted with 25 Dutch and 30 Indian international assignees (IAs) and repatriates in both India and The Netherlands. Thematic analysis resulted in four themes: met and unmet expectations of career advancement opportunities; knowledge transfer and labour marketability; economic growth versus economic recession and alternative employment opportunities; and boundaryless careers: adventure and entrepreneurship.

Findings
– Repatriate expectations about the use of knowledge, skills and abilities gained in the host country moderate the relationship between the macro-economic situation of the home country and repatriate attrition/retention, such that met expectations of Indian respondents decreased their intention to leave the organisation, even in a conducive macro-economic context with ample alternative employment opportunities. Unmet expectations of Dutch respondents increased their intention to leave the organisation, even in an unfavourable macro-economic context with few alternative employment opportunities.

Research limitations/implications
– The sample of Indian and Dutch IAs and repatriates may limit generalisation of the findings to samples from other countries with distinct cultural contexts and macro-economic conditions.

Practical implications
– Global organisations that set realistic expectations about re-entry career opportunities for repatriates, facilitate knowledge transfer after repatriation, and adequately respond to boundaryless career ambitions of repatriates, can reduce repatriate turnover intention and attrition.

Originality/value
– This study shows that repatriate attrition versus retention is embedded in the macro-economic context of the home country, leading to three types of career mobility upon completion of an international assignment: intra-organisational mobility; organisational boundary-crossing; and geographical boundary crossing.
Impact of non-normal return and market capitalization on estimation of VaR
Authors: Sinha Pankaj , Agnihotri Shalini 
Published: July 2015

Purpose
– This paper aims to investigate the effect of non-normality in returns and market capitalization of stock portfolios and stock indices on value at risk and conditional VaR estimation. It is a well-documented fact that returns of stocks and stock indices are not normally distributed, as Indian financial markets are more prone to shocks caused by regulatory changes, exchange rate fluctuations, financial instability, political uncertainty and inadequate economic reforms. Further, the relationship of liquidity represented by volume traded of stocks and the market risk calculated by VaR of the firms is studied.

Design/methodology/approach
– In this paper, VaR is estimated by fitting empirical distribution of returns, parametric method and by using GARCH(1,1) with Student’s t innovation method.

Findings
– It is observed that both the stocks, stock indices and their residuals exhibit non-normality; therefore, conventional methods of VaR calculation are not accurate in real word situation. It is observed that parametric method of VaR calculation is underestimating VaR and CVaR but, VaR estimated by fitting empirical distribution of return and finding out 1-a percentile is giving better results as non-normality in returns is considered. The distributions fitted by the return series are following Logistic, Weibull and Laplace. It is also observed that VaR violations are increasing with decreasing market capitalization. Therefore, we can say that market capitalization also affects accurate VaR calculation. Further, the relationship of liquidity represented by volume traded of stocks and the market risk calculated by VaR of the firms is studied. It is observed that the decrease in liquidity increases the value at risk of the firms.

Research limitations/implications
– This methodology can further be extended to other assets’ VaR calculation like foreign exchange rates, commodities and bank loan portfolios, etc.

Practical implications
– This finding can help risk managers and mutual fund managers (as they have portfolios of different assets size) in estimating VaR of portfolios with non-normal returns and different market capitalization with precision. VaR is used as tool in setting trading limits at trading desks. Therefore, if VaR is calculated which takes into account non-normality of underlying distribution of return then trading limits can be set with precision. Hence, both risk management and risk measurement through VaR can be enhanced if VaR is calculated with accuracy.

Originality/value
– This paper is considering the joint issue of non-normality in returns and effect of market capitalization in VaR estimation.
Innovation in fit-outs – are Generation Y and technology firms heralding a new trend?
Authors: Gillen Nicola , Cheshire David 
Published: July 2015

Purpose
– The purpose of this paper is to understand how is the workplace changing with the age-range of its workforce? Why is happiness and wellness in the workplace being prioritised more than ever before? Will the workplace of the future be designed as a serviced experience rather than the office that is known today? This paper aims to examine these questions, and why the answer might be found in the influence of Generation Y and technology organisations.

Design/methodology/approach
– The approach to this paper is to draw from a number of sources – AECOM’s published paper for the BCO on how the TMT sectors are impacting office design – extensive AECOM project experience and research in practice. The presentation prepared for cutting edge was the starting point for the structure and content of this paper.

Findings
– The authors are designing for multiple generations at work, not just the youngest people. The authors can learn much, however, from the trends being set by the youngest sectors, such as technology organisations with their Generation X board members driving speed, informality and a work/life blend. The next generation workplace will be designed with more emphasis on diversity, choice, flexibility and sustainability. The office will be as much about the experience and service provision as the physical space supporting people holistically for a happier, healthier and more productive workforce.

Research limitations/implications
– There are multiple topics addressed in this paper. Research and findings are drawn from other sources. New research is beyond the scope of this paper.

Practical implications
– Looking ahead, developers and architects will need to reuse empty office space in other ways. The city block of the future must be mixed-use, vertically and horizontally, and incorporate offices, residential, dining, leisure and co-working, with a permeable, linked-up ground floor. City blocks today are sometimes segregated, designed as separate buildings in one, with separate entrances breaking up the ground floor into separate domains. The city block of the future needs to be more joined up, more connected and open at ground floor level to allow a mix of people and functions, creating more public space.

Social implications
– The opportunity is to create sustainable and highly utilised environments where people can work, live and socialise.

Originality/value
– Drawing from the AECOM proprietary global occupancy database which contains 25 years of data of how buildings are actually used over time. This paper includes the data for the last ten years. Applying the reality of four generations in the workplace to the design of office buildings.
