Detecting environment-dependent diversification from phylogenies: a simulation study and some empirical illustrations
Authors: Lewitus Eric , Morlon Hélène 
Published: July 2017

AbstractUnderstanding the relative influence of various abiotic and biotic variables on diversification dynamics is a major goal of macroevolutionary studies. Recently, phylogenetic approaches have been developed that make it possible to estimate the role of various environmental variables on diversification using time-calibrated species trees, paleoenvironmental data, and maximum-likelihood techniques. These approaches have been effectively employed to estimate how speciation and extinction rates vary with key abiotic variables, such as temperature and sea level, and we can anticipate that they will be increasingly used in the future. Here we compile a series of biotic and abiotic paleodatasets that can be used as explanatory variables in these models and use simulations to assess the statistical properties of the approach when applied to these paleodatasets. We demonstrate that environment-dependent models perform well in recovering environment-dependent speciation and extinction parameters, as well as in correctly identifying the simulated environmental model when speciation isenvironment-dependent. We explore how the strength of the environment-dependency, tree size, missing taxa, and characteristics of the paleoenvironmental curves influence the performance of the models. Finally, using these models, we infer environment-dependent diversification in three empirical phylogenies: temperature-dependence in Cetacea,δ13C-dependence in Ruminantia, andCO2-dependence in Portulacaceae. We illustrate how to evaluate the relative importance of abiotic and biotic variables in these three clades and interpret these results in light of macroevolutionary hypotheses for mammals and plants. Given the important role paleoenvironments are presumed to have played in species evolution, our statistical assessment of how environment-dependent models behave is crucial for their utility in macroevolutionary analysis.

Published: July 2017

PurposeThe purpose of this paper is to guide the choice of consumers, putting on the label an additional claim, which can provide more information on the sensory profile and the nutritional and preservation features of the marketed extra virgin olive oil.Design/methodology/approachIn order to define the concept of global quality, the following parameters were considered: fruity, bitter, pungency, 1-penten-3-one, phenolic substances, tocopherols, peroxide value, free acidity, palmitic acid, stearic acid oleic acid linoleic acid, and the campesterol/stigmasterol ratio. The study was carried out on 143 commercial extra virgin olive oils.FindingsThe Global Quality Index was calculated as the square root of the sum of the squares of the individual local indices, according to three different algorithms. The computation obtained was recognised by chemometric analysis.Social implicationsA legislative amendment on the labelling could be proposed through an additional claim that safeguards the consumers on the health profile, inducing them to a more targeted purchase.Originality/valueThree different global quality levels “excellent”, “good”, and “sufficient” have been determined. This clustering has also been recognised with a statistical approach. Since in the market, consumers can find extra virgin olive oils of different overall quality levels, it is possible to guide the choice of customers through an additional claim on the label, able to give more information on the sensory profile and the nutritional and preservation features of the product.

Authors: Fonseca Maciel Leonardo , Felício Ana Lúcia de Souza Madureira , Hirooka Elisa Yoko 
Published: July 2017

Purpose
Many factors can influence the bioactive compounds in cocoa beans. The purpose of this paper is to characterize the bioactive compound profile of 12 cocoa bean clones produced in Bahia’s Southern region.

Design/methodology/approach
Total phenolic content, total flavonoids and total anthocyanins were determined using spectrophotometric methods. Caffeic acid, caffeine, theobromine, catechin and epicatechin contents were determined using Ultra Performance Liquid Chromatography with a Photodiode Array Detector. Principal component analysis (PCA) was carried out using to determine the variability of the results found in relation to the clones studied.

Findings
The authors observed variations in the bioactive compound content between the analyzed cocoa clones. The SRN clone showed the highest levels of phenolic content, flavonoids, caffeine, catechin, and epicatechin. PCA showed that all the clones had unique characteristics related to the composition of their bioactive compounds content, classifying each clone in a well-defined manner.

Originality/value
This work is an important contribution for the characterization of new cocoa bean clones in relation to their content of bioactive compounds. The information reported in this paper can be decisive in the choice of the variety of cocoa in the production of chocolate with high bioactive compounds content and claim of functional property.
Modeling rice grain-type preferences in Bangladesh
Authors: Mottaleb Khondoker Abdul , Rahut Dil Bahadur , Mishra Ashok K. 
Published: July 2017

Purpose
The purpose of this paper is to examine the rice consumption by rice grain types under the rising income scenario in Bangladesh. Generally, with an increase in income, households tend to consume more food items that are high-value, enriched foods and protein, such as meat and fish, by substituting for cereals. However, consumers also substitute when it comes to grain quality. For example, cereals, such as rice, are available in a range of qualities from the ordinary type (coarse-grain) to the premium type (fine grain). The authors postulate that as household incomes increase, households may consume more premium-type rice (or fine-grain rice), while overall consuming less rice or fewer carbohydrates.

Design/methodology/approach
Using the Bangladesh Household Income and Expenditure Survey 2000, 2005, and 2010, and applying multivariate probit and seemingly unrelated regression estimation procedures, this study quantifies the impact of income, household demographics, and urbanization on rice consumption by rice grain types (coarse-grain, medium-grain, and fine-grain types).

Findings
The results show that urban, wealthy households and, households headed by educated heads and spouses, are more likely to consume fine-grain rice than their counterparts.

Originality/value
After yield, grain type is the second most important factor for farmers when considering the adoption of a new variety. The price of rice and other cereals is highly associated with the grain type. This study concludes that plant breeding programs of major cereals, such as rice and wheat, should take into account the consumer grain-type preferences when developing new varieties.
Who is the purchaser of nutrition-labelled products?
Authors: Smed Sinne , Edenbrandt Anna Kristina , Koch-Hansen Pia , Jansen Leon 
Published: July 2017

Purpose
The purpose of this paper is to determine how the typical purchasers of products with nutrition symbols differ from other purchasers with respect to socio-demographic characteristics. Furthermore the authors examine if the typical purchaser is similar across six product types in Denmark and in the Netherlands.

Design/methodology/approach
The authors estimate probit models using a representative panel of households registering all their daily purchases during a year, three years after the introduction of a nutrition symbol in Denmark and the Netherlands (the Keyhole and the Choices). The purchase data are matched with information about labelling status. Other product and purchase characteristics, such as store-type and organic, are controlled for.

Findings
Households with children tend to have a lower probability of purchasing labelled products compared to other household types, while urbanity increases the probability. This holds both across countries and across products. In Denmark education is positively correlated with label purchase, while in the Netherlands it is income. Generally, the observable characteristics of the consumers are poor in explaining the probability of purchasing labelled products which suggests that other aspects as the underlying attitudes and general health awareness may be of greater importance in identifying these consumers.

Originality/value
There is a lack of studies analysing the effect of front-of-pack symbols on households’ product choices based on observed data as most previous studies are based on stated observation or purchase intentions.
Opt-in or opt-out: exploring how women construe their ambition at early career stages
Authors: Harman Charlotte , Sealy Ruth 
Published: July 2017

PurposeThe purpose of this paper is to challenge existing models of career ambition, extending understanding of how women define and experience ambition at early career stages in a professional services organisation.Design/methodology/approachSemi-structured interviews were conducted with 20 women from a professional services organisation, who were aged 24-33 and had not yet reached managerial positions. The interviews were recorded, transcribed and template analysis was conducted.FindingsThe analysis revealed four main themes in the women’s experiences: subjective, dynamic ambition; frustrated lack of sight; self-efficacy enables ambition; and a need for resilience vs a need to adapt. The findings support that women do identify as ambitious, but they vary in the extent to which they view ambition as intrinsic and stable, or affected by external, contextual factors, such as identity-fit, barriers, support and work-life conflict.Research limitations/implicationsThese results demonstrated insufficiency of current models of ambition and a new model was proposed. The model explains how women’s workplace experiences affect their ambition and therefore how organisations and individuals can better support women to maintain and fulfil their ambitions.Originality/valueThis study extends and contributes to the redefinition of women’s career ambition, proposing a model incorporating women’s affective responses to both internal (psychological) and external (organisational) factors. It provides further evidence against previous individual-level claims that women “opt-out” of their careers due to an inherent lack of ambition, focussing on the interplay of contextual-level explanations.

Published: July 2017

PurposeThe purpose of this paper is to investigate the mediating role of innovative behavior on the relationships between organizational structure, such as centralization, formalization, integration, and organizational innovation performance.Design/methodology/approachThe authors collected data from 140 functional managers of manufacturing organizations in the Republic of Korea. The authors used structural equation modeling procedure to evaluate the validity of proposed hypotheses.FindingsThe results suggest that innovative behavior mediates the links among centralization, formalization, and organizational innovation performance. However, the findings indicate that innovative behavior does not mediate the relationship between integration and organizational innovation performance.Originality/valueThis work is the first to examine the mediating role of innovative behavior on the associations among centralization, integration, and organizational innovation performance.

Authors: Gordon Katy , Wilson Juliette , Tonner Andrea , Shaw Eleanor 
Published: July 2017

PurposeThe purpose of this paper is to examine the impacts of social enterprise on individual and community health and well-being. It focusses on community food initiatives, their impact on the social determinants of health and the influence of structure on their outcomes.Design/methodology/approachUsing an interpretive qualitative approach through case studies focussed on two community food social enterprises, the research team conducted observations, interviews and ad hoc conversations.FindingsResearchers found that social enterprises impacted all layers of the social determinants of health model but that there was greater impact on individual lifestyle factors and social and community networks. Impact at the higher socio-economic, cultural and environmental layer was more constrained. There was also evidence of the structural factors both enabling and constraining impact at all levels.Practical implicationsThis study helps to facilitate understanding on the role of social enterprises as a key way for individuals and communities to work together to build their capabilities and resilience when facing health inequalities. Building upon previous work, it provides insight into the practices, limitations and challenges of those engaged in encouraging and supporting behavioural changes.Originality/valueThe paper contributes to a deeper insight of the use, motivation and understanding of social enterprise as an operating model by community food initiatives. It provides evidence of the impact of such social enterprises on the social determinants of health and uses structuration theory (Giddens, 1984) to explore how structure both influences and constrains the impact of these enterprises.

Authors: Jain Varsha , Pich Christopher , Ganesh B.E. , Armannsdottir Guja 
Published: July 2017

PurposeThe extant literature demands more insights into the elements for political branding in India. Thus, this paper aims to explore political branding in terms of the influences of political branding.Design/methodology/approachThe context is the young voters in an emerging country, India. Qualitative research was undertaken, and a total of 17 focus group discussions were conducted in the leading Indian cities.FindingsThis study found that the Bhartiya Janata Party (BJP) developed a strong governance and connection with the people. This approach developed a comprehensive brand among the young voters, who emphasized on the proof of the performance by the party. During pre or post-election, the BJP and other political parties need to develop a comprehensive political branding plan to connect with the voters.Research limitations/implicationsThis study was focused on the external perspective of political branding. Future research can focus on the internal perspective in terms of party members and politicians. This study has focused on India as a specific case. Future studies can focus on a cross-cultural and cross-national level.Practical implicationsThe framework developed can be used by political parties and leaders to develop their political brand. The study’s framework can be used in a systematic and sequential format to verify the strength of their political branding exercise.Originality/valueThis study focuses on the post-election scenario. Secondly, it focuses on the non-Western context. Also, the study represents a unique combination of the best theories and observations from political marketing and digital leadership.
Exploring nature of workplace bullying and psychometric properties of negative acts questionnaire-revised (NAQ-R) in Indian organizations
Authors: Rai Arpana , Agarwal Upasna A 
Published: July 2017

PurposeAn extensive amount of literature is available on workplace bullying in the Western context. With specific reference to the Indian context, there is limited literature on nature of workplace bullying in Indian organizations as well, as there is no valid instrument to measure the prevalence of workplace bullying in Indian organizations. This paper aims to explore the nature of workplace bullying in Indian organization and examine the psychometric properties of Negative Acts Questionnaire-Revised (NAQ-R) in Indian context.Design/methodology/approachData were collected through a hardcopy version of a survey from 835 Indian managers during working hours.FindingsThe analysis identified three major categories and constituent sub-categories of bullying behaviors. The NAQ-R was found appropriate on psychometric criteria.Research limitations/implicationsGender-blind perspective towards approaching bullying and no sector-wise differentiation in nature of bullying are the limitations of the study.Practical implicationsAn understanding of nature of workplace bullying in Indian organizational may help managers to identify and timely intervene the bullying situations. This study can help to strengthen the potentialities of NAQ-R as a major organizational diagnosis measure for examining bullying in Indian organizations. A validation of NAQ-R would also help to stimulate the academic work on bullying in India and allow for cross-cultural comparison of studies.Originality/valueThis is the first study to examine psychometric properties of the NAQ-R in Indian settings.
National culture and the learning organization
Authors: Siddique C. Muhammad 
Published: July 2017

PurposeThis paper aims to examine the concept of learning organization (LO) in the United Arab Emirates (UAE). Its objective is to provide initial insight into the potential impact of cultural context on how business managers perceive and interpret the LO theory and practice.Design/methodology/approachThe study was conducted in two phases; the first phase involved a focus group review and discussion of the LO concept and major LO models. With insights gained from the focus group discussions, the second phase of the study developed a number of hypotheses on the potential impact of national cultural orientations on the LO concept, which were tested with managerial responses to a survey.FindingsWhile UAE managers viewed and interpreted the LO concept in several different ways, most qualitative comments emphasized the following four aspects of an LO: workplace learning, organizational learning, learning climate and learning structure. Both sets of data revealed strong linkages between dimensions of national culture and the LO concept. Organizational culture partially mediated the relationship between national cultural orientations and aspects of an LO. Potential barriers to the implementation of the LO concept as perceived by respondents were largely related to national cultural value orientations and organizational cultures. The findings suggested that Western LO models and measurement instruments do not fully capture the socio-cultural reality of UAE-based organizations and the manner in which they view and interpret the LO concept and practices in their specific context.Research limitationsBeing a preliminary and largely reflective in nature, the present study has relied more heavily upon the qualitative data than the survey data.Practical implicationsThe findings of this study document the value of culture-specific criteria to monitor the performance of companies in their LO journey rather than using a standardized LO assessment model.Originality/valueThe study represents an initial attempt at enhancing the understanding of the impact of national culture on the development and application of the LO concept and the challenges it faces in the UAE context.

Authors: Cimirotić Rusmir , Duller Verena , Feldbauer-Durstmüller Birgit , Gärtner Bernhard , Hiebl Martin R.W. 
Published: July 2017

PurposeAlthough the number of women working in management accounting has increased, the percentage of female executives in this area remains low. Previous studies examining the underrepresentation of women in accounting leadership positions have analyzed factors that hinder women from reaching these positions. The purpose of this paper, by contrast, is to identify factors that support the advancement of those female executives who have reached a leadership position. Further, this paper highlights the self-reported obstacles and difficulties faced by respondents in reaching their current positions.Design/methodology/approachSemi-structured interviews were conducted face-to-face with ten female executives in the management accounting departments of Austrian firms. The interview transcripts were analyzed by using the general inductive approach.FindingsThe results of the study show that most women classified their social skills and professional expertise as the key factors leading to their successful advancement; however, they also highlighted that ambition and luck played important roles. The authors found that support from both life partners and superiors was essential for these women in reaching their current positions and in handling difficulties when in a leadership position. Further difficulties include working time, work-life balance and motherhood.Research limitations/implicationsAs the findings are based on interviews conducted with female Austrian executives in large (more than 250 employees) manufacturing- or service-sector firms, they are not readily generalizable.Practical implicationsThis study identifies factors that may help prospective female management accounting executives reach leadership positions. Furthermore, less senior female management accountants may learn from this paper that women who have already reached leadership positions in management accounting may have had to cope with problems similar to those that younger and less senior female management accountants currently experience.Originality/valueThis paper is among the first to address gender in the field of management accounting.

Authors: Yap Jeffrey Boon Hui , Goh Seh Vian 
Published: July 2017

Purpose
The purpose of this paper is to explore the potential of transit-oriented development (TOD), the perceptions of buyers and the establishment of the comfortable walking distance. The literature indicates the requirement of TOD with increasing population in major cities.

Design/methodology/approach
In this study, exploratory sequential mixed methods research approach was adopted. Semi-structured interviews were conducted followed by questionnaire survey. The respondents were categorised based on their generation cohorts to further understand their acuities on TOD.

Findings
The key consideration factors when buying houses in the TOD area are as follows: amenities related to jobs and family for Baby Boomers; time saving for Generation Y; and location for Generation X, i.e. house should be conveniently located in relation to working place, school, etc. Communities in Malaysia are willing to walk for five to ten minutes (approximately 400 to 800 m).

Research limitations/implications
Future studies can be enlarged to include other major cities in Malaysia and draw comparisons with neighbouring ASEAN countries.

Practical implications
This paper provides insights to property developers, consultants and government agencies for product development. Ultimately, TOD is the innovative sustainable solution for high-density urban planning and development.

Social implications
TOD is a sustainable development concept that encourages the use of public transportation system in order to reduce private motor vehicles usage.

Originality/value
This paper emphasises the potential of TOD, explores the perceptions of different generation cohorts in relation to TOD and establishes the comfortable walking distance for Malaysian communities. It also highlights the key factors of conveniences for TOD.
