Strategic groups and local railway development in China
Authors: Yan Karl 
Published: April 2020

PurposeWhat are the mechanisms through which Chinese municipal leaders overcome implementation breakdown? This study, through process tracing, archival work and semi-structured interviews, examines the implementation of three sub-municipal-level railway projects involving the same principals and agents over the same period of time.Design/methodology/approachThe analysis was guided by the hypothesis that political coordination and the exercise of political and Party leadership played an indispensable role in the two cases of successful policy implementation, and its absence accounts for the case of implementation breakdown.FindingsThe principal finding is that an informal “strategic group” was created to “herd” cadres to overcome the problem of implementation. Herding here refers to the idea that Party leadership, through the use of moral persuasion, encourages cadres moving towards a desired common goal and direction.Research limitations/implicationsThis study is limited in the number of secondary resources (government documents and government and media releases) available to the field interviewees, which the author heavily relied on to complete the study.Originality/valueBuilding on the conceptual work of “strategic groups” by Thomas Heberer, Anna Ahlers, and Gunter Schubert, this study makes an empirical contribution by tracing the process through which an informal strategic group exercises its power to overcome implementation breakdown.
Can digital solutions help in the minimization of out-of-home waste? An analysis from the client and business perspective
Authors: Secondi Luca , Principato Ludovica , Mattia Giovanni 
Published: April 2020

PurposeHalving food waste has been included within the 17 UN Sustainable Development Goals. Food wasted out-of-home is the second source of food waste. However, the majority of the studies have focused on home generated food waste, and still little is known about out-of-home food waste and how it is managed by food service companies. The purpose of this paper is to adopt a double perspective in analyzing food waste generated at a food service level, by focusing on both the client and business perspective.Design/methodology/approachFirst, from the client perspective, the authors aim at analyzing consumer out-of-home habits, self-reported waste quantification, and doggy bag usage by reporting the results of an exploratory survey which involved 411 individuals living in central Italy. Second, from a business perspective, the authors analyzed an award-winning practice that manages out-of-home food waste in Italy by combining food surplus management and digital solutions with a profitable business model innovation.FindingsResults obtained from the two perspectives of analysis support the need of business investments in innovations and digital solutions, in order to meet client needs and behavior, thus contributing to better manage and reduce food surplus and waste.Practical implicationsThis study will raise practitioners’ knowledge on the advantages of digital solution in food surplus management, along with a better comprehension on food waste behavior from the client perspective.Originality/valueThis is the first study that analyses out-of-home waste from both the client and business perspective, emphasizing how digital solutions can help in reducing the phenomenon.
Leading properties of GDT auctions for dairy prices
Authors: Olipra Jakub 
Published: April 2020

PurposeProfessionals from the dairy sector commonly believe that the results of Global Dairy Trade (GDT) auctions are a good leading indicator for prices of dairy commodities. The purpose of this paper is to test that hypothesis for prices of key dairy commodities (skimmed milk powder (SMP), whole milk powder (WMP), butter and cheddar) in the main dairy markets (the US, EU and Oceania).Design/methodology/approachThe leading properties of the GDT auctions are investigated using vector error correction models (VECM).FindingsThe results show that prices at GDT auctions may be treated as a benchmark for global prices of WMP and SMP as they affect prices in all considered markets. However, in case of EU market the relationship with the GDT is bidirectional. GDT prices reveal some leading properties also in cheddar market, however price relationships in this market are much more complex. In case of butter market, GDT can be regarded as a benchmark only for Oceania.Practical implicationsThe results of this paper improve knowledge on price transmission in dairy markets, show the role of the GDT auctions in the price setting process, and thus may help professionals from the dairy sector to formulate their price expectations more precisely.Originality/valueDespite the fact that many professionals from the dairy sector treat GDT auctions as a benchmark, so far their leading properties have not been scientifically proven.
Topic: chemical compositions and mineral content of four selected South African herbal teas and the synergistic response of combined teas
Authors: Malongane Florence , McGaw Lyndy Joy , Mudau Fhatuwani Nixwell 
Published: April 2020

PurposeThe present study was carried out to determine (1) essential minerals, total polyphenols, total flavonoids, moisture and ash of four selected South African herbal teas and (2) the effect of blending bush tea with other known commercial herbal teas.Design/methodology/approachThe method used to determine moisture and ash contents followed that of the Association of Official Analytical Chemists (AOAC). Nine minerals were analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES). The total phenolic and flavonoid contents were determined by Folin–Ciocalteu assay and aluminum chloride colorimetric assay, respectively.FindingsThe results of the study demonstrated that bush tea had a high ash content of 8.01% and special tea (9.23%), while honeybush (1.96%) and rooibos tea (2.17%) exhibited a low ash percentage. The mineral content was higher in bush tea and special tea than in rooibos tea and honeybush tea except for sodium, which was higher in rooibos tea. The blending of bush tea with special tea improved its potassium content from 22,937.00 mg/kg to 23,379.20 mg/kg. Blending bush tea with rooibos tea at a ratio of 25:75 increased the flavonoid content to 12.21 µg/mL.Research limitations/implicationsThe results of the nutrients composition cannot be generalized as it is influenced by other factors such as soil type and seasons.Social implicationsIncreasing the commercialization of indigenous teas.Originality/valueThe results of the study suggest that bush tea and special tea are nutritionally comparable with South African commercial herbal teas. Thus, the consideration for commercialization of these teas is crucial.

Authors: Bonsaksen Tore , Heir Trond , Skogstad Laila , Grimholt Tine K. , Ekeberg Øivind , Lerdal Anners , Schou-Bredal Inger 
Published: April 2020

Purpose
Harmful use of alcohol is a major public health problem. While harm is often researched in the context of heavy drinking episodes, high-frequency drinking, even when drinking moderate quantities, constitutes a health risk in a longer perspective. The purpose of this paper is to examine the prevalence of daily use of alcohol in the Norwegian general population and to assess sociodemographic, mental health-related and personal resource variables associated with daily use of alcohol.

Design/methodology/approach
A cross-sectional survey concerned with health, illness and serious life events was distributed to 5,500 persons in the general population in Norway (response rate 36%). Sociodemographic variables, personal resource variables (general self-efficacy, optimism and extraversion) and psychological distress (current anxiety and/or depression) were assessed with regards to their associations with daily drinking in unadjusted and adjusted regression models.

Findings
Daily use of alcohol was reported by 39 persons (2.2%) in the sample (3.1% of men and 1.4% of women). While general self-efficacy, optimism and extraversion were unrelated to daily drinking, the adjusted model revealed that male sex (OR: 2.18, p < 0.05), being unemployed/not in education (OR: 3.10, p < 0.05) and reporting current anxiety and/or depression (OR: 3.12, p < 0.01) were associated with daily use of alcohol.

Originality/value
The study has contributed to the knowledge about daily drinkers in a representative sample of the Norwegian population. A proportion of 2.2% was found to drink alcohol on a daily basis. Compared to their counterparts, the odds of daily drinking were higher for men, unemployed persons and persons reporting current psychological distress. Public health initiatives aiming at reducing harmful use of alcohol may pay particular attention to these subsets of the population.

Authors: Hobiny Aatef , Alzahrani Faris S. , Abbas Ibrahim 
Published: April 2020

Purpose
The purposes of this study, a generalized model for thermoelastic wave under three-phase lag (TPL) model is used to compute the increment of temperature, the components of displacement, the changes in volume fraction field and the stress components in a two-dimension porous medium.

Design/methodology/approach
By using Laplace-Fourier transformations with the eigen values methodologies, the analytical solutions of all physical variables are obtained.

Findings
The derived methods are estimated with numerical outcomes which are applied to the porous media in simplified geometry.

Originality/value
Finally, the outcomes are represented graphically to display the difference among the models of the TPL and the Green and Naghdi (GNIII) with and without energy dissipations.

Authors: Mambet Doue Constance , Navarro Carrascal Oscar , Restrepo Diego , Krien Nathalie , Rommel Delphine , Lemee Colin , Coquet Marie , Mercier Denis , Fleury-Bahi Ghozlane 
Published: April 2020

Purpose
Based on social representation theory, this study aims to evaluate and analyze the similarities and differences between social representations of climate change held by people living in two territories, which have in common that they are exposed to coastal risks but have different socio-cultural contexts: on the one hand, Cartagena (Colombia) and on the other, Guadeloupe (French overseas department, France).

Design/methodology/approach
A double approach, both quantitative and qualitative, of social representation theory was adopted. The data collection was undertaken in two phases. First, the content and organization of social representation of climate change (SRCC) was examined with a quantitative study of 946 participants for both countries, followed by a qualitative study of 63 participants for both countries also.

Findings
The study finds unicity in the SRCC for the quantitative study. In contrast, the qualitative study highlights differences at the level of the institutional anchoring of the climate change phenomenon in these two different socioeconomic and political contexts.

Practical implications
These results are relevant for a reflection in terms of public policies for the prevention and management of collective natural risks, as well as for the promotion of ecological behavior adapted to political and ideological contexts.

Originality/value
The use of a multi-methodological approach (quantitative and qualitative) in the same research is valuable to confirm the importance of an in-depth study of the social representations of climate change because of the complexity of the phenomenon.
Meta-analysis of outcomes of leader–member exchange in hospitality and tourism: what does the past say about the future?
Authors: Chang Wen , Liu Anyu , Wang Xuhui , Yi Bowen 
Published: April 2020

Purpose
Leader–member exchange (LMX) theory is particularly relevant to the hospitality and tourism industry due to its labor-intensive and service-focused nature. However, the hospitality literature regarding the impact of LMX on its various outcomes have inconsistent results. A holistic review of LMX studies is nonexistent in the current literature. Thus, the purpose of this study is to use a meta approach to quantitatively summarize and examine the relationship between LMX and its outcomes in the hospitality and tourism literature.

Design/methodology/approach
A total of 89 individual observations from 36 studies conducted between 1997 and 2018 were identified. A Bayesian random effect model was introduced into the hospitality and tourism literature for the first time to implement the meta-analysis.

Findings
The results suggest significant differences in the impact of LMX on various groups of outcomes. LMX has the strongest impact on firms’ practice-related outcomes, such as organizational justice and employee empowerment. Few moderators are identified on the impact of LMX, such as LMX measure, culture, industry sector and statistical method.

Practical implications
Findings yielded several recommendations for both hospitality researchers and organizations in developing LMX related studies, as well as managing employees.

Originality/value
This study is the first Bayesian meta-analysis in the hospitality and tourism literature; it complements LMX theory by linking it to cognitive appraisal theory. Specific characteristics of LMX in the hospitality and tourism industry, such as the measurement of LMX and the effect of industry sector, are also identified.
The effect of hotel investments on employment in the tourism, leisure and hospitality industries
Authors: Dogru Tarik , McGinley Sean , Kim Woo Gon 
Published: April 2020

Purpose
The purpose of this paper is twofold: first, to examine the extent to which hotel investments create jobs and, second, to compare whether investment in a particular hotel segment generates more or less jobs in the overall economy and in the tourism, leisure and hospitality industries.

Design/methodology/approach
The panel autoregressive distributed lag regression model was used to examine the effect of total hotel investments and hotel investments in economy-scale, midscale, luxury-scale and independent hotels on total employment and employment in the tourism, leisure and hospitality industries in the USA.

Findings
Hotel investments increase employment in both the overall economy and the tourism, leisure and hospitality industries. Midscale hotels make the highest contribution to employment in the overall economy. Economy-scale hotels make the highest contribution to employment in the overall tourism, leisure and hospitality industries.

Research limitations/implications
The results support the postulations of growth pole theory. As hotel investment increases, not only does the hotel industry see gains in employment but also does related economic sectors see an increase. Midscale hotels have the greatest positive impact on local labor markets, which is consistent with the assertions of middle-out economics.

Practical implications
Community leaders should encourage the type of investment that benefits the broader area as much as possible by incentivizing the type of growth that is related to employment growth.

Originality/value
This study investigates the relations between hotel investment and employment from a theoretical and empirical perspective by providing objective claims inferred from statistical inferences.
Definitive guidelines toward effective mobile devices crowdtesting methodology
Authors: Naith Qamar , Ciravegna Fabio 
Published: April 2020

PurposeThis paper aims to gauge developers’ perspectives regarding the participation of the public and anonymous crowd testers worldwide, with a range of varied experiences. It also aims to gather their needs that could reduce their concerns of dealing with the public crowd testers and increase the opportunity of using the crowdtesting platforms.Design/methodology/approachAn online exploratory survey was conducted to gather information from the participants, which included 50 mobile application developers from various countries with diverse experiences across Android and iOS mobile platforms.FindingsThe findings revealed that a significant proportion (90%) of developers is potentially willing to perform testing via the public crowd testers worldwide. This on condition that several fundamental features were available, which enable them to achieve more realistic tests without artificial environments on large numbers of devices. The results also demonstrated that a group of developers does not consider testing as a serious job that they have to pay for, which can affect the gig-economy and global market.Originality/valueThis paper provides new insights for future research in the study of how acceptable it is to work with public and anonymous crowd workers, with varying levels of experience, to perform tasks in different domains and not only in software testing. In addition, it will assist individual or small development teams who have limited resources or who do not have thousands of testers in their private testing community, to perform large-scale testing of their products.
Is the meaning of ethical leadership constant across cultures? A test of cross-cultural measurement invariance
Authors: Ahmad Saima , Fazal-e-hasan Syed , Kaleem Ahmad 
Published: April 2020

PurposeThis paper empirically addresses the question of whether the meaning of ethical leadership is constant across cultures. Drawing on the implicit leadership theory (ILT), we examine whether people in Australia and Pakistan respond to perceived ethical leadership in a similar or different manner. By comparing employees' interpretation of the key attributes associated with ethical leadership, we advance construct-specific knowledge in cross-national contexts.Design/methodology/approachSince meaningful cross-country comparisons of a research construct require an equivalent measurement of it, we examine the issue of cross-cultural measurement invariance of ethical leadership. Specifically, this study explores the configural, metric and scalar invariance of ethical leadership by obtaining data from matched international samples.FindingsThe findings broadly support cross-cultural generalisability of the construct's meaning and cross-cultural transferability of the ethical leadership scale (ELS). They suggest that measures of ethical leadership constructs should be used in different cultures with caution because significant differences may exist at the item level.Originality/valueThis study provides cross-cultural endorsement to the construal of ethical leadership by presenting evidence that supports convergence in the construct's meaning across Eastern and Western cultures. The study has enhanced the construct validity of ethical leadership through the use of the refined multiple-sample analytical approach. Previous studies have assumed that measures of ethical leadership are invariant across various contexts. However, this is the first study to employ a robust methodological technique (metric and path invariance) that demonstrates the significant difference between each item and path and generalises the validity of ethical leadership construct and its measures by using international samples.
SME productivity stakeholders: getting in the right orbit
Authors: Jones Oliver William , Gold Jeff , Devins David 
Published: April 2020

PurposeThe purpose of this paper is to explore who small and medium-sized enterprise (SME) owner–managers consider as key stakeholders for their business for helping increase productivity and the nature of the stakeholders' impact.Design/methodology/approachThe study uses the Lego Serious Play methodology and narrative analysis in a focus group setting.FindingsThe analysis revealed a narrow depth of field of productivity stakeholders and identified critical narratives, involving close stakeholders which could constrain productivity. Lack of information on current and/or future productivity states, and a social brake due to the potential impact on employees are two at the forefront of owner–manager perspectives. The study also identified the importance of internal and external champions to improve productivity and re-enforced the significance of skills gaps, the role of Further Education providers and other infrastructure assets.Research limitations/implicationsThe purposiveness sample of the single focus group setting results in a lack of generalizability, but provides potential for replication and transposability based on the generic type of stakeholders discussed. The work highlights the potential to further enhance the constituent attributes of stakeholder salience.Practical implicationsThere is a potential for different network agents to increase their collaboration to create a more coherent narrative for individual productivity investment opportunities and for policy makers to consider how to leverage this.Social implicationsThe findings suggest that the implications of deskilling and job loss are major factors to be considered in the policy discourse. SMEs are less likely to pursue productivity improvements in a low growth setting because of their local social implications.Originality/valueThe study is innovative in using Lego to elucidate narratives in relation to both stakeholder identification and their contributions to productivity improvement impact in a UK SME context. The study introduces an innovative stakeholder orbital map and further develops the stakeholder salience concept; both useful for the future conceptual and empirical work.
Online decision aids: the role of decision-making styles and decision-making stages
Authors: Virdi Preeti , Kalro Arti D. , Sharma Dinesh 
Published: April 2020

PurposeDecision aids (DAs) in online retail stores ease consumers' information processing. However, online consumers do not use all decision aids in purchase decision-making. While the literature has documented the effects of individual decision aids or two decision aids at a time, no study has compared the efficacy of multiple decision aids simultaneously. Also, very few studies have looked at the use of decision aids for consumers with maximizing and satisficing tendencies. Hence, this study aims to understand the preferences of maximizers and satisficers towards online decision aids during the choice-making process.Design/methodology/approachThis is an observational study with 60 individuals who were asked to purchase either a search-based or an experience-based product online. Participants' browsing actions and verbalizations during online shopping, were recorded and analysed using NVivo, and later the use of decision aids was mapped along their choice process.FindingsConsumer's preference of decision aids varies across the two stages of the choice process (that is, consideration set formation and evaluation & choice). In their choice formation, maximizers use different decision aids in both stages, that is, filter tool and in-website search tool for search products, and collaborative filtering-based recommender systems and eWOM for experience products. Satisficers used more decision aids as compared to maximizers across the two stages for both product types.Originality/valueThis study is an exploratory attempt to understand how consumers use multiple decision aids present on e-commerce websites.
