Paid educational leave and self-directed learning
Authors: Oh Jeong Rok , Park Cho Hyun , Jo Sung Jun 
Published: March 2016

Purpose
– The purposes of this study are to explore paid educational leave (PEL), self-directed learning (SDL) and the relationship between them; and to identify the implications for legislation on the learning leave scheme in South Korea.

Design/methodology/approach
– The research method of the study is a literature review. Articles were identified through a keyword search from major academic databases. The literature search covers the time period of 1960-2012.

Findings
– This paper shows that enacting PEL is a social policy that benefits to both employers and workers because it reduces training costs, eliminates educational barriers for employees and enhances opportunities to develop skills and competencies.

Research limitations/implications
– This study contributes to research by exploring the crucial role of PEL based on the Person-Process-Context model for SDL. It also examines the relationship between SDL and PEL in the workplace learning.

Practical implications
– This study provides a rationale to legislate PEL as a right of workers. Through an appropriate revision of the Lifelong Education Act, the right of workers to receive the PEL benefit should be legally adopted to promote workers’ SDL in South Korea.

Originality/value
– This paper provides theoretical and practical evidence for institutionalizing PEL in South Korea. It suggests the passage of PEL legislation because it is beneficial to all stakeholders.
Wine experts’ rating: a matter of taste?
Authors: Cardebat Jean-Marie , Livat Florine 
Published: March 2016

Purpose– Given the lack of consensus among wine experts, this paper aims to examine whether this implies they make systematic mistakes or is an expression of their idiosyncratic preferences.Design/methodology/approach– Grade equations are estimated for five famous wine-experts and a panel of 62 Bordeaux fine wines over the period 2003-2011. The appellation of origin is considered a measure of the typical taste of the wines. The authors control for objective factors, thanks to weather variables and the ranking of each wine.Findings– Ratings vary among experts, such that some statistically significantly favour wines produced in specific areas, indicating their taste preferences. Thus, preferences matter in expert ratings and would seem to suggest a continental variance. The finding explains the lack of consensus in this opinion market.Social implications– The lack of consensus among wine experts should not necessarily be viewed as market inefficiency. If consumers find the “right expert” reflecting their own tastes, as in the case of cultural goods, they may not necessarily experience a welfare loss due to expert opinion heterogeneity.Originality/value– This paper contributes to renewing the debate on expert accuracy, considering wine as a cultural good and introducing preferences into the analysis. The authors develop the concept according to which existing differences in the personal tastes of the experts can facilitate consumer search.
Positioning fast moving luxury goods in a discount environment
Authors: Priilaid David 
Published: March 2016

Purpose
– This paper aims to understand how a fast moving luxury good like whisky is typically positioned within South Africa’s discounted retail environment and how this positioning could be improved. So doing this paper introduces an econometric valuation model to establish the relative efficacy of contending extrinsic cues in the explanation of whisky prices.

Design/methodology/approach
– An ordinary least squares regression model is developed from a data set of 122 whiskies drawn from the 2014 festive-season catalogues of two large South African discount retailers. In estimating the whisky pricing function, the hedonic contribution of the following input variables is estimated: age in respect of blended whiskies and single premium malts, in-store supply, claims of retail exclusivity, branding, country-of-origin and packaging formats.

Findings
– Age effects as they relate to single malts, and mass produced grain whiskies offer the greatest explanation of price, while scarcity effects are observed, along with claims of retail exclusivity which are found to reduce product value significantly. Country-of-origin and packaging however have low to negligible effects.

Originality/value
– To producers and marketers of whisky, these findings offer insight as to which extrinsic factors could be better amplified, modified or excised if the product is to be optimally positioned. Implications are explored.
What characterises luxury products? A study across three product categories
Authors: Sjostrom Therese , Corsi Armando Maria , Lockshin Larry 
Published: March 2016

Purpose
– This study aims to test whether the attributes developed via qualitative or conceptual approaches link to the concept of luxury when measured using a quantitative approach. Given the critical role price has in the definition and identification of luxury products, this research measures whether the use of different attributes is exclusively associated with the highest price points in each category or whether there is some level of sharing with lower price points.

Design/methodology/approach
– A total of 431 respondents sociodemographically representative of the Australian population were screened for familiarity with the category and then randomly assigned to one of three product categories (wine, spirits and perfume). Best–worst scaling was used to measure the associations between different attributes and the concept of luxury, while the pick-any method was used to measure the association of different attributes to different price points.

Findings
– The findings are consistent across the three categories investigated, i.e. “premium quality”, “authentic/trustworthy brand” and “good brand reputation/status”, are much more associated with luxury than with regular brands. “Luxury”, “premium”, “antique/old vintage”, “limited production/edition” and “premium price” consistently cluster around the highest price point in each category, while the other attributes tested did not.

Originality/value
– Despite the plethora of research about attributes associated with the luxury concept, this is the first study attempting to measure the size of the association. The consistency of the results across the three product categories is encouraging in terms of the generalisability of the results for future research.
Why share expertise? A closer look at the quality of motivation to share or withhold knowledge
Authors: Stenius Minna , Hankonen Nelli , Ravaja Niklas , Haukkala Ari 
Published: March 2016

Purpose
The purpose of this study is to investigate the role of motivation for knowledge sharing (KS) by assessing how four qualitatively different motivation types, as per self-determination theory (SDT), predict KS, its quality and its undesirable counterpart, knowledge withholding.

Design/methodology/approach
The study was carried out as a survey (n = 200) in an expert organization. The analyses were conducted using structural equation modeling.

Findings
Autonomous type of extrinsic motivation (identified motivation) was the strongest predictor of KS (in work meetings) and its quality, whereas the other motivation types (intrinsic, introjected and external) had no independent contribution to variance in KS. Knowledge withholding was negatively associated with identified and positively with external KS motivation.

Research limitations/implications
Single organization limits the generalizability of the results. Future studies should further investigate the role of identified motivation for various KS behaviors.

Practical implications
The findings suggest that autonomy-supportive management practices known to facilitate self-determined behavior can improve KS. Fostering external motivation by incentivizing KS may be both ineffective and have undesirable consequences.

Originality/value
Few prior studies investigate KS motivation beyond external and intrinsic motivation or apply SDT to KS using SDT-based scales. This study distinguishes between four different motivation types and is the first to investigate their differential impact on KS and its quality. It is also the first to demonstrate the importance of identified motivation for KS. It further elucidates how the quality of KS motivation is reflected in knowledge withholding, an overall underinvestigated behavior.
Knowledge management in small and medium enterprises: a structured literature review
Authors: Massaro Maurizio , Handley Karen , Bagnoli Carlo , Dumay John 
Published: March 2016

Purpose
This paper aims to review and critique the knowledge management (KM) literature within small and medium enterprises (SMEs), offers an overview of the state of research and outline a future research agenda.

Design/methodology/approach
Papers published in KM journals are analysed using a structured literature review methodology. The paper analyses 89 papers published in ten journals specialising in the field of KM.

Findings
KM within SMEs is a research area of growing importance. Findings show that literature on KM in SMEs is fragmented and dominated by unrelated research, with few comparative studies between countries and several countries receiving little attention. Additionally, different definitions of SMEs are used and different kinds of SMEs (e.g. micro, small and medium) are often treated as equivalent, making comparison almost impossible. The results show a failure to address the implications of findings for practitioners and policymakers, which risks relegating the KM research on SMEs to irrelevance.

Originality/value
The paper presents a comprehensive structured literature review of the articles published in KM journals. The paper’s findings can offer insights into future research avenues.
The impact of (low) trust on knowledge sharing
Authors: Rutten Werner , Blaas-Franken Joyce , Martin Harry 
Published: March 2016

PurposeThis paper aims to explore the differences in the level of knowledge sharing between co-workers in high versus low trust situations, for cognition-based trust and for affect-based trust as well as implicit and explicit knowledge.Design/methodology/approachThe differences were examined through data provided by 102 professionals working for a financial organization in The Netherlands.FindingsThe differences in the level of knowledge sharing in high versus low trust situations are significant. The effect is larger for affect-based trust and for implicit knowledge.Research limitations/implicationsThe survey has been conducted within one organization only.Practical implicationsOrganizations should realize the importance of trust between their co-workers, and in general, there is much to gain by increasing the levels of trust between co-workers, as this will also increase knowledge sharing between co-workers.Originality/valuePrevious studies have not examined the situation of low trust and its effect on the level of knowledge sharing within a homogeneous group of co-workers.
The TramArt experience: domesticating graffiti in public transport
Authors: Arroyo Moliner Liliana , Clavell Gemma Galdon 
Published: March 2016

Purpose
This paper aims at presenting an example of the good practice of crime prevention through environmental design (CPTED). The initiative has been carried out by a private tram company in Spain to tackle graffiti. Their main goal was to avoid graffiti defacing in their underground stations, and artists were involved in the design and execution. The intervention consisted of a combined strategy of CPTED measures (anti-graffiti coatings and paintings) with a comprehensive use of the space, turning stations from transit points into poetic spaces, generating emotions and a sense of belonging. The features also included an urban graffiti gallery.

Design/methodology/approach
This case study presents and describes the actions undertaken from the early stages of problem framing to execution and a soft assessment of the results obtained. All the information provided has been gathered through four semi-structured interviews with managers and designers of the experience.

Findings
The TramArt experience is an example of the shift in the mindset of transport operators regarding graffiti and graffiti artists. All interventions have been designed by the transport operator in cooperation with situational artists. As a result, the tram stations and vehicles are not conceived either as non-lieux or canvas, but spaces with a singular identity, with the possibility of generating a sense of belonging among passengers and users. The first intervention was tested in 2004 in one station and three years later was deployed in three more stops. According to the initiators, its impact has been mainly positive in terms of success rates, cost reduction and general satisfaction and security perception of passengers. However, the urban gallery has been more problematic to maintain.

Research limitations/implications
This research focuses on the transport operator perspective basically and views expressed by transport users are indirectly assessed. While the change in the angle may be scalable, the specific features depend to a great extent on particular conditions, such as the size of the company, the resources available and the characteristics of the area covered.

Originality/value
The value of this case relies in the constructive approach towards graffiti, which goes one step further than the broken windows theory and the criminalisation of graffiti by default. It departs from prevention to enhancement of the prosocial aspects of graffiti, as well as providing a new conception of transit spaces.
A good beginning
Authors: Gerhardt Sue 
Published: March 2016

Purpose– The purpose of this paper is to examine the physiological systems – the foundation of physical and mental health – that are being established during gestation and early infancy, when babies are also highly vulnerable to stress.Design/methodology/approach– This paper provides a brief overview of some of these processes.Findings– The author argues that despite the wealth of research affirming the special significance of pregnancy, babyhood and toddlerhood in human development, the predominant political and cultural institutions go on failing to protect new parents and their relationships with their infants. The current policies and practices are short-sighted.Originality/value– The author shows that there is a failure to recognise the significance of good emotional regulation – learnt in secure early relationships – to a thriving society.
High and low levels of positive mental health: are there socioeconomic differences among adolescents?
Authors: Nielsen Line , Stewart-Brown Sarah , Vinther-Larsen Mathilde , Meilstrup Charlotte , Holstein Bjørn E. , Koushede Vibeke 
Published: March 2016

Purpose
– It is important within public health goals to promote adolescents’ mental health and to reduce socioeconomic inequalities in mental health. Among adults there are indications that the socioeconomic pattern of low positive mental health (PMH) differs from the socioeconomic pattern of high PMH. Knowledge regarding the social epidemiology of PMH among young people is lacking. The purpose of this paper is to examine the socioeconomic patterning of aspects of low and high PMH among adolescents.

Design/methodology/approach
– The Health Behaviour in School-aged Children Methodology Development Study 2012 provided data on 3,670 adolescents aged 11-15 in two municipalities in Denmark. Socioeconomic differences in aspects of low and high PMH (self-esteem, social competence and self-efficacy) were investigated by calculating sex-specific prevalence of PMH in socioeconomic groups measured by parents’ occupational social class. Using multi-level logistic regression analyses, odds ratios for low and high PMH compared to moderate PMH were estimated.

Findings
– In age-adjusted analyses there seemed to be a graded relationship with increasing odds for low PMH with decreasing socioeconomic position, but no indication of a socioeconomic patterning of high PMH. The prevalence of high self-esteem and high self-efficacy was higher among boys than girls. High social competence and high self-efficacy increased with age.

Research limitations/implications
– Public health research has primarily focused on risk factors and mental health problems. Research highlighting more detailed aspects of PMH is needed.

Originality/value
– The socioeconomic pattern of high PMH may be different from the socioeconomic pattern of low PMH.
Adolescent mental health: new hope for a “Survive, Thrive and Transform” policy response
Authors: Baltag Valentina , Servili Chiara 
Published: March 2016

Purpose– Mental health problems make a significant contribution to morbidity and mortality in adolescents worldwide. To address mental health in adolescents policy response should intertwine the life course approach and the ecological model that positions adolescents in the context of multifactorial influences. The purpose of this paper is to describe policy response at four levels: multisector policies and interventions, health systems policies and interventions, evidence-based clinical interventions and actions to monitor progress. It aims to analyse the implications for adolescent mental health of key recent global commitments including the sustainable development goals (SDGs) and the Global Strategy for Women’s, Children’s and Adolescents’ Health.Design/methodology/approach– Multisector policies and interventions on determinants of adolescent mental health and well-being are drawn from the Global Strategy for Women’s, Children’s and Adolescents’ Health. Key health systems actions are derived from the Comprehensive Mental Health Action Plan (2013-2020). In both cases, policies and interventions are made specific for provisions relevant to adolescents. Examples of implementation of policies and interventions are drawn from a World Health Organization (WHO) review of national policy documents found in WHO MiNDbank. A list of indicators to monitor progress is being proposed based on Mental Health Atlas and WHO indicators for adolescent health.Findings– With some notable exceptions, the mental health of adolescents is not adequately addressed by national health policies. There is a considerable body of evidence on the effectiveness of policies and interventions, and recent global commitments give new hope for promoting adolescent mental health through a multisectoral response, within which the health sector has an important role to play. Global reporting mechanisms, including the Mental Health Atlas, should be “adolescent-sensitive”, meaning that adolescent specific impact, outcomes, inputs and determinants should be measured, reported and acted upon.Originality/value– This paper analyses the meaning specific to adolescents in the policies and interventions promoted in the SDGs, the Global Strategy for Women’s, Children’s and Adolescents’ Health and the Comprehensive Mental Health Action Plan (2013-2020). For the first time a four-levels policy response specific to adolescent mental health is put together: multisector policies and interventions, health systems policies and interventions, evidence-based clinical interventions and actions to monitor progress.
Process enhancement for maximization of methane production in codigestion biogas plants
Authors: Capodaglio Andrea G , Ranieri Ezio , Torretta Vincenzo 
Published: March 2016

Purpose– The purpose of this paper is to develop improvements in the efficiency of the codigestion process.Design/methodology/approach– Two pilot plants, fed by different compositions of manure and industrial organic waste, generating biogas by mesophilic and thermophilic anaerobic fermentation, respectively, were analysed.Findings– It was observed that these processes do not commonly operate at maximum theoretical efficiency.Research limitations/implications– The limiting factor in the process was found to be the hydrolysis of the digested material.Practical implications– A technical solution had been suggested: implementing a secondary (after) storage phase which has the purpose of exploiting, by promoting enhanced hydrolysis, the substrate potential that remains undigested after the traditional process.Originality/value– The proposed configuration opens to original variations in the anaerobic digestion schemes.
Chemometric modeling to predict aquatic toxicity of benzene derivatives in Pimephales Promelas
Authors: Ziani Nadia , Amirat Khadidja , Messadi Djelloul 
Published: March 2016

Purpose
– The purpose of this paper is to predict the aquatic toxicity (LC50) of 92 substituted benzenes derivatives in Pimephales promelas.

Design/methodology/approach
– Quantitative structure-activity relationship analysis was performed on a series of 92 substituted benzenes derivatives using multiple linear regression (MLR), artificial neural network (ANN) and support vector machines (SVM) methods, which correlate aquatic toxicity (LC50) values of these chemicals to their structural descriptors. At first, the entire data set was split according to Kennard and Stone algorithm into a training set (74 chemicals) and a test set (18 chemical) for statistical external validation.

Findings
– Models with six descriptors were developed using as independent variables theoretical descriptors derived from Dragon software when applying genetic algorithm – variable subset selection procedure.

Originality/value
– The values of Q2 and RMSE in internal validation for MLR, SVM, and ANN model were: (0.8829; 0.225), (0.8882; 0.222); (0.8980; 0.214), respectively and also for external validation were: (0.9538; 0.141); (0.947; 0.146); (0.9564; 0.146). The statistical parameters obtained for the three approaches are very similar, which confirm that our six parameters model is stable, robust and significant.
Photochromic Textiles and Measurement of Their Temperature Sensitivity
Authors: Vikova Martina , Vik Michal 
Published: March 2016

Our previous papers (Viková & Vik, 2005) described a unique device, now patented in the Czech Republic in the author's name, for photochromic measurement in a reflectance mode together with a methodology. This device allows photochromic sensors to test the colorimetric and spectral characteristics of photochromic textiles, and also fatigue tests for control of colour change stability. This concept of colorimetric and spectral parameters also finds the dependence of colour change on the intensity of UV irradiation and temperature. In this paper, we would like to describe the dependence of colour change on temperature for the photochromic Photopia AQ Ink system (Blue, Purple and Yellow) produced by Matsui Shikiso Chemical Co.Ltd.
It is known that the reversion of photochromic compounds from coloured to colourless is promoted thermally. The photochromic structure can achieve a lower level of saturated absorbance at higher temperatures when thermo reversible photochromic systems, such as spirooxazines and chromenes, increase the rate of thermal bleaching reaction and thus decrease light stimulated coloration.
