Author-related factors predicting citation counts of conference papers: focusing on computer and information science
Authors: Lee Danielle 
Published: May 2020

PurposeThis paper aims to assess the predictive power of authorship properties determined at the time of publishing conference papers on future citations of conference papers in computer and information science.Design/methodology/approachThis study examined 21 factors – related to all authors and to the first author – as potentially predictive of citation counts. Specifically, the study assessed properties of author's academic performance, degree of collaboration and topological properties of their research collaboration networks.FindingsThe results of comparing all authors with first authors indicate that the all author-related factors have a significantly higher power for explaining conference paper citation counts than the first author-related factors. Moreover, among the all author-related factors, the degree centrality before the target paper made the largest contribution.Originality/valueThis is one of the first attempts to focus on the relationship of author characteristics to conference papers. This is also one of only a few studies to expand prior research, which limited its bibliometric foci to journal articles, to conference papers.
Testing the efficacy of a brief-caries risk assessment form to evaluate the dental health status among preschool children, Bangkok, Thailand
Authors: Saengtipbovorn Saruta 
Published: May 2020

PurposeThe study aims to test the efficacy of brief-caries risk assessment form with standard caries risk assessment form and to evaluate the application of caries risk assessment following American Academy of Pediatric Dentistry (AAPD) between brief and standard caries risk assessment on dental health status among preschool children.Design/methodology/approachBrief-caries risk assessment form was developed. Then, experimental study was conducted in public health center 54 among 70 patients (35 test and 35 control) from January to July 2019. Test group used brief-caries assessment form, and control group used standard form. Both groups received the same caries risk assessment criteria and management protocol from AAPD. At baseline, 3-month and 6-month follow-up, caries risk and dental health status (plaque index, cavitated caries lesion and non-cavitated caries lesion) were assessed. Data were analyzed by descriptive statistic,t-test, chi-square test, Fisher's exact test and repeated measures ANOVA.FindingsPercentage of high caries risk decreased from baseline (93.9%: test and 96.9%: control) to 6-month follow-up (66.7%: test and 65.6%: control) in both groups, with no statistically significant differences between groups. Plaque index, cavitated caries lesion and non-cavitated caries lesion were not statistically significant differences between groups. Brief-caries assessment decreased times/visit from 10-15 minutes to 5 minutes.Originality/valueBrief-caries assessment form decreased caries risk and prevented dental caries as the standard form. Using brief-caries assessment form could save time, is cost-effective and is appropriate for use in public health centers. However, a short follow-up time might have insufficient power to detect the differences between groups.
The impact of product variety on fill rate, inventory and sales performance in the consumer goods industry
Authors: Santos Victor , Sampaio Mauro , Alliprandini Dario Henrique 
Published: May 2020

PurposeThe impact of product variety decisions on fill rate, inventory and sales performance in a consumer goods company has been examined. From a marketing perspective, it is possible to leverage sales, reach new segments and consequently increase competitiveness when there is a greater product variety on the market. However, operations and logistics professionals indicate potential impacts on the supply chain, such as production, storage and distribution complexity. The nature of the product variety-cost-sales performance relationship is not clear, and empirical evidence about whether and how operations cost and sales performance increases with variety is inconclusive.Design/methodology/approachThe multiple linear regression and the Tobit regression techniques were applied over a seven-year horizon of data from a business intelligence platform of a consumer goods company.FindingsOur results show that sales performance is negatively associated with product variety. The total effect of product variety on sales performance has been examined, including both the direct effect and the indirect effect through inventory and fill rate. Therefore, the findings provide a comprehensive understanding of the impact of product variety on operations and sales performance.Originality/valueSeveral studies have researched the impact of product variety on fill rate, inventory and sales performance separately; however, the research of the impact and the relationship of these factors is scarce and limited.
The initial impacts of Minimum Energy Efficiency Standards (MEES) in England
Authors: Sayce Sarah Louise , Hossain Syeda Marjia 
Published: May 2020

PurposeThe paper investigates the initial impacts on asset management and valuation practice of the Minimum Energy Efficiency Standard (MEES) introduced in England and Wales from April 2018 for new lettings.Design/methodology/approachThe paper reports findings from a small-scale pilot study of valuers, asset managers, lawyers and building consultants. Interviews were conducted over the summer of 2019 and explored the impact on practice and market values and perceived links to the carbon reduction agenda. Data were analysed thematically manually and using NVivo software.FindingsParticipants welcomed MEES but many had doubts about the use of energy performance certificates (EPCs) as the appropriate baseline measure. Compliance was perceived as too easy; further, enforcement is not occurring. Vanguard investors have aligned portfolios for carbon reduction; others have not. Lease practices are changing with landlords seeking greater control over tenant behaviours. Valuers reported that whilst MEES consideration is embedded in due diligence processes, there is limited value impact.Research limitations/implicationsThe study is limited by its small-scale and that the MEES regulations are not yet fully implemented. However, the research provides early findings and lays out recommendations for future research by identifying areas in which the regulations are/are not proving effective to date.Practical implicationsThe findings will inform investors, consultants and policy makers.Social implicationsAchieving energy efficiency in buildings is critical to driving down carbon emission; it also has economic and social benefits through cost savings and reducing fuel poverty.Originality/valueBelieved to be the first post-implementation qualitative study of MEES.
Benefit segmentation of a summer destination in Uruguay: a clustering and classification approach
Authors: Perera Gonzalo , Sprechmann Martin , Bourel Mathias 
Published: May 2020

Purpose
This study aims to perform a benefit segmentation and then a classification of visitors that travel to the Rocha Department in Uruguay from the capital city of Montevideo during the summer months.

Design/methodology/approach
A convenience sample was obtained with an online survey. A total of 290 cases were usable for subsequent data analysis. The following statistical techniques were used: hierarchical cluster analysis, K-means cluster analysis, machine learning, support vector machines, random forest and logistic regression.

Findings
Visitors that travel to the Rocha Department from Montevideo can be classified into four distinct clusters. Clusters are labelled as “entertainment seekers”, “Rocha followers”, “relax and activities seekers” and “active tourists”. The support vector machine model achieved the best classification results.

Research limitations/implications
Implications for destination marketers who cater to young visitors are discussed. Destination marketers should determine an optimal level of resource allocation and destination management activities that compare both present costs and discounted potential future income of the different target markets. Surveying non-residents was not possible. Future work should sample tourists from abroad.

Originality/value
The combination of market segmentation of Rocha Department’s visitors from the city of Montevideo and classification of sampled individuals training various machine learning classifiers would allow Rocha’s destination marketers determine the belonging of an unsampled individual into one of the already obtained four clusters, enhancing marketing promotion for targeted offers.
Asymmetric relationship of investor sentiment with stock return and volatility: evidence from India
Authors: Chakraborty Madhumita , Subramaniam Sowmya 
Published: May 2020

PurposeThe study examines the cross-sectional and asymmetric relationship of investor sentiment with the stock returns and volatility in India.Design/methodology/approachThe investor sentiment is captured using a market-based measure Market Mood Index (MMI) and a survey-based measure Consumer Sentiment Index (CSI). The asymmetric effect of the relationship is examined using quantile causality approach and cross-sectional effect is examined by considering indices such as the BSE Sensex, and the various size indices such as BSE Large cap, BSE Mid cap and BSE Small cap.FindingsThe result of the study found that investor sentiment (MMI) cause stock returns at extreme quantiles. Lower sentiment induces fear-induced selling, thereby lowers the returns and high sentiment is followed by lower future returns as market reverts to fundamentals. On the other hand, bullish shifts in sentiment lower the volatility. There exists a positive feedback effect of stock return and volatility in the formation of investor sentiment.Originality/valueThe study captures both asymmetric and cross-sectional relationship of investor sentiment and stock market in an emerging economy, India. The study uses a novel data set (i.e.) MMI which captures the sentiment based on market indicators and are widely disseminated to the public.
Exploring CSR’s influence on employees’ attitudes and behaviours in higher education
Authors: Mascarenhas Carla , Mendes Luis , Marques Carla , Galvão Anderson 
Published: May 2020

Purpose
Despite the recognised importance of corporate social responsibility (CSR) in higher education institutions (HEIs), research concerning CSR’s influence on employees’ attitudes and behaviours is still understudied. Grounded in the theory of social identity, this study aims to explore CSR’s impact on employees’ work engagement, job satisfaction and organisational identification in an HEI context.

Design/methodology/approach
Data were collected in a northern Portugal public HEI through a self-administered questionnaire distributed to both teaching and supporting staff. A structural equation modelling (SEM) approach was applied to data collected from 171 employees, using the partial least squares-SEM approach.

Findings
Overall, the findings show that CSR is strongly associated with work engagement, job satisfaction, identification with the organisation and perceived organisational support, confirming the hypothesised influence of HEI’s CSR development efforts on study-related attitudes.

Practical implications
Findings reinforce the need for HEIs to integrate CSR and human resource strategies and to pay special attention to CSR communication strategies.

Social implications
Findings reinforce the need for HEI to develop adequate CSR strategies because these have a significant influence on employees’ satisfaction at work, and thus on employees’ well-being in general.

Originality/value
This study contributes to attenuate the lack of literature on CSR’s impacts on employee behaviours.
Testing social and environmental disclosure-reputation relationship: a longitudinal two-way analysis
Authors: Castilla-Polo Francisca , Sánchez-Hernández M. Isabel 
Published: May 2020

PurposeThis paper aims to review sustainability reporting understood as any type of social and environmental disclosures (SED) in its relationship with corporate reputation within the most reputed companies in Spain according to MERCO business monitor ranking (2014-2016).Design/methodology/approachTo shed light on the relationship reputation-SED, two alternative models were tested, thought the use of structural equation model (SEM) and partial least squares (PLS), with longitudinal data.FindingsBoth models supported the hypotheses although the model linking reputation to SED was slightly better, questioning the use of SED by reputation leader companies.Research limitations/implicationsThe paper study the linkage, sign and causality, between reputation and SED by introducing two alternative models. SED and reputation are receiving considerable attention into the business scope, although their relationship is not agreed by previous literature. There are contradictory evidences that lead us to question the sense of this relation.Practical implicationsThe contribution will be of interest to managers in terms of the value of this type of reporting from a strategic point of view. If reputation favours this type of disclosures, these will be issues to be taken into account to obtain a better competitive advantage through market differentiation.Social implicationsThe results will be of interest for future studies and actions aimed at regulating the improvement of this type of reporting not only in the hands of academics and practitioners but also investors and regulators.Originality/valueThis study is an advance in the description of the SED-reputation relationship and contributes to this new line of research with new insights. Another contribution is the way to understand sustainability reporting. This paper analyses SED from the twofold point of view of the quantity of information and, the existing references about its quality and adding the lag effect between both variables.
Assessing the relationship between closing prices and trading volume in the US livestock futures markets
Authors: Panagiotou Dimitrios , Tseriki Alkistis 
Published: May 2020

Purpose
The purpose of this paper is to examine the relationship between closing prices and trading volume in the livestock futures markets of lean hogs, live cattle and feeder cattle.

Design/methodology/approach
The parametric quantile regressions methodology is used. Daily data between January 1, 2010 and July 31, 2019 were used.

Findings
Findings suggest that the relationship between the two variables is non-linear. Price-volume relationship is positive (negative) under positive (negative) returns. Furthermore, co-movement is weaker at the lower quantiles and stronger at the higher quantiles. Results are in line with the empirical findings of the price-volume relationship in six agricultural futures markets from the study by Fousekis and Tzaferi (2019).

Originality/value
This is the first study that uses the parametric quantile regressions method in the livestock futures market, to examine the returns-volume dependence.
Institutions, human capital and economic growth in developing countries
Authors: Uddin Md Akther , Ali Md Hakim , Masih Mansur 
Published: May 2020

PurposeThis paper aims to study institutions, human capital and economic growth in developing countries.Design/methodology/approachThe study applies dynamic system Generalized Method of Moments (GMM) and simultaneous quantile regression on a panel of 120 developing countries for the period of 1996-2014.FindingsThe findings show that human development and institutions do have a significant positive effect on economic growth. Interestingly, institutions and human development have a significant negative interactive effect on the economic growth of developing countries. This paper argues that incremental investment in human development would impact economic growth negatively in the presence of weak and dysfunctional institutions because additional stock tends to be employed in rent-seeking and socially unproductive activities.Research limitations/implicationsThe policy makers should bear in mind the critical role played by the institutions and the initial stage of growth of a country in making their education and health policies more effective.Originality/valueThe most important novelty is the study of various transmission channels: political, economic and financial institutions through which human development affect economic growth in developing countries. This paper also studies the Islamic economic development concept and empirically investigates whether Muslim countries are different from their counterparts. Moreover, this study extends the existing empirical growth literature by simultaneously applying dynamic system GMM and quantile regression techniques.
To bee or not to bee: The ‘raison d'être’ of toxic secondary compounds in the pollen of Boraginaceae

Abstract

While the presence of secondary compounds in floral nectar has received considerable attention, much less is known about the ecological significance and evolutionary origin of secondary ‘toxic’ compounds in pollen. It is unclear whether the presence of these compounds in pollen is non‐adaptive and due to physiological ‘spillover’ from other floral tissues, or whether these compounds serve an adaptive function related to plant–pollinator interactions, such as protection of pollen against pollen thieves.

Combining an experimental approach with phylogenetic comparative methods, and using western Palaearctic Boraginaceae as a model system, we investigate how pollen secondary metabolites influence, and are influenced by, relationships with bees, the main functional group of pollen‐foraging pollinators.

We found a significant relationship between the levels of secondary compounds in the corollas and those in the pollen in the investigated species of Boraginaceae, suggesting that baseline levels of pollen secondary compounds may partly be due to spillover from floral tissues. At realistic levels, pollen secondary compounds showed significant detrimental effects on bee pre‐imaginal development, in agreement with previous egg‐transfer experiments showing that in some cases Boraginaceae pollen did not support pre‐imaginal development in bees not specialized on these plants.

We also show that phylogenetically independent Boraginaceae taxa rewarding pollinators with pollen in addition to nectar exhibit significantly lower levels of toxic compounds in the pollen than taxa where the main reward is postulated to be nectar. Lastly, in contrast to our predictions, there was no positive association between toxin levels in the pollen of a given plant taxon and the number of bee species specialized on this taxon.

We integrate all these findings and formulate an evolutionary scenario to account for the presence of toxic compounds in the pollen of Boraginaceae. We suggest that baseline levels of toxic compounds may be found in pollen due to spillover from other floral tissues and not primarily because of bee–flower interactions. Since pollen toxins can have detrimental effects on bees, we propose that selection acts to lower pollen toxin levels in plants where pollen, in addition to nectar, serves as a reward to bees.

Sources of variation in maternal allocation in a long‐lived mammal
Authors: Macdonald Kaitlin R. , Rotella Jay J. , Garrott Robert A. , Link William A. 
Published: May 2020

Abstract

Life history theory predicts allocation of energy to reproduction varies with maternal age, but additional maternal features may be important to the allocation of energy to reproduction.

We aimed to characterize age‐specific variation in maternal allocation and assess the relationship between maternal allocation and other static and dynamic maternal features.

Mass measurements of 531 mothers and pups were used with Bayesian hierarchical models to explain the relationship between diverse maternal attributes and both the proportion of mass allocated by Weddell seal mothers, and the efficiency of mass transfer from mother to pup during lactation as well as the weaning mass of pups.

Our results demonstrated that maternal mass was strongly and positively associated with the relative reserves allocated by a mother and a pup's weaning mass but that the efficiency of mass transfer declines with maternal parturition mass. Birthdate was positively associated with proportion mass allocation and pup weaning mass, but mass transfer efficiency was predicted to be highest at the mean birthdate. The relative allocation of maternal reserves declined with maternal age but the efficiency of mass transfer to pups increases, suggestive of selective disappearance of poor‐quality mothers.

These findings highlight the importance of considering multiple maternal features when assessing variation in maternal allocation.
Developmental underpinnings of spermatogonial stem cell establishment
Authors: Law Nathan C. , Oatley Jon M. 
Published: May 2020

AbstractBackgroundThe germline serves as a conduit for transmission of genetic and epigenetic information from one generation to the next. In males, spermatozoa are the final carriers of inheritance and their continual production is supported by a foundational population of spermatogonial stem cells (SSCs) that forms from prospermatogonial precursors during the early stages of neonatal development. In mammals, the timing for which SSCs are specified and the underlying mechanisms guiding this process remain to be completely understood.ObjectivesTo propose an evolving concept for how the foundational SSC population is established.Materials and methodsThis review summarizes recent and historical findings from peer‐reviewed publications made primarily with mouse models while incorporating limited studies from humans and livestock.Results and conclusionEstablishment of the SSC population appears to follow a biphasic pattern involving a period of fate programming followed by an establishment phase that culminates in formation of the SSC population. This model for establishment of the foundational SSC population from precursors is anticipated to extend across mammalian species and include humans and livestock, albeit on different timescales.
Preoperative anaemia and thrombocytopenia are associated with venous thromboembolism complications after colorectal resection
Authors: Yeap Evie , Teoh William M.K. , Nguyen Thang Chien , Suhardja Thomas Surya 
Published: May 2020

AbstractBackgroundEarlier studies have shown that abnormal levels of haemoglobin and platelets may be associated with worse post‐operative outcomes. We aim to compare the rates of venous thromboembolism (VTE), anastomotic leak and other complications in patients post‐colorectal resection with normal and abnormal levels of haemoglobin and platelets.MethodsWe performed a retrospective review of 1610 patients from July 2010 to June 2015 in a single colorectal unit. Our primary outcome was the rate of VTE and anastomotic leak in anaemic and thrombocytopenic patients. Secondary outcomes included length of stay, 30‐day mortality, return to theatre, transfusion rates and Clavien–Dindo classification complications.ResultsVTE complications were more common in anaemic patients, and this difference became more pronounced with the severity of anaemia. Other complications such as length of stay >2 weeks occurred more frequently in anaemic and thrombocytopenic patients. A trend towards higher rates of 30‐day mortality and anastomotic leak was noted in patients with anaemia and thrombocytopenia.ConclusionAnaemia and thrombocytopenia are associated with worse outcomes including length of stay, anastomotic leak, VTE and 30‐day mortality.
