Overeducation, persistence and unemployment in Spanish labour market
Authors: Sánchez-Sánchez Nuria , Fernández Puente Adolfo Cosme 
Published: July 2020

PurposeThe phenomenon of overeducation and the magnitude and persistence of the imbalance impact are analysed for the Spanish labour market from 2006 to 2013.Design/methodology/approachThe authors present random-effects probit estimations comparing individuals and their short-term and long-term labour mismatches.FindingsThe results support the existence of long-term persistence (status in the previous year) and short-term persistence (status at the beginning of the observed period) in overeducation. Precariousness in the labour market, measured by temporality or by the strong destruction of employment, could force individuals to choose a job below their qualification. Additionally, the phenomenon of overeducation is shown to have increased in the period 2010–2013 in relation to the period 2006–2009 independently of the region considered, though those regions with higher unemployment rates display greater imbalances.Research limitations/implicationsAlthough the results come from two different samples, it is possible to conclude that overeducation is a phenomenon that tends to perpetuate over time in Spain.Practical implicationsOne of the issues of greatest interest that is crucial to assess the relevance of the spreading of overeducation is whether overeducation can be considered as a temporal mismatch, in which case the seriousness of the problem would not be so important, or, on the contrary, as a persistent one, in which case, governments should take it into account in their education reform programmes.Originality/valueOvereducation persistence has been studied in countries such as the United States, Canada, Switzerland or Germany; however, in Spain, there are hardly any studies. Spanish labour market has certain specificities that make the analyses relevant: the high unemployment rates and high elasticity of employment with respect to the economic cycles. Under these circumstances, workers could opt for more stable positions that require a lower qualification than the one they have. This option could be even more convenient during crisis. Additionally, the article includes a disaggregated analysis by Spanish regions. The differences in the unemployment rates within and between regions are significant (some of them had at the beginning of the crisis an unemployment rate close to 7%, while in others it exceeded 12%) which allows the authors to study the phenomenon in different contexts.
Human-wildlife interactions for tourism: a systematic review
Authors: Dou Xueting , Day Jonathon 
Published: July 2020

PurposeThis paper aims to synthesize the key findings of prior research on the topic of human-wildlife interactions (HWI) in natural places for tourism.Design/methodology/approachThe methodology of systematic review was used to search for, appraise and analyze the relevant research evidence. A total of 47 English-language academic journal articles, published between 2003 and 2018, with free online access to full texts in the database of Hospitality and Tourism Complete have been reviewed. Thematic analysis was adopted to synthesize the textual data.FindingsThe reviewed articles cover a wide geographical spread, diverse wildlife species and interaction types, and various research focuses including ecological impacts, human dimensions and management issues of wildlife tourism. The interactions between wildlife and human systems in the context of tourism constitute a complicated social-ecological system, in which both the humans and animals can be affected positively and negatively. Management and scientific research provide the nexus between the ecological and human dimensions of wildlife tourism. While opportunities for sustainable development abound, challenges are not to be neglected.Originality/valueDue to the complexity of wildlife encounters for tourist purposes, the extant literature indicates a diverse and fragmented view from which integrated implications are difficult to obtain. This paper presents the first overarching review in English of the literature on human-wildlife interactions for tourism and provides a big picture understanding of what has been and what is needed to be done in terms of both wildlife tourism research and practices.
Social capital, knowledge sharing, work meaningfulness and creativity: evidence from the Pakistani pharmaceutical industry
Authors: Bhatti Sabeen Hussain , Vorobyev Dmitriy , Zakariya Ramsha , Christofi Michael 
Published: July 2020

PurposeAs an integral part of intellectual capital (IC), social capital (SC) has been studied as an asset crucial to social relationships among individuals and groups of individuals, which in turn have a significant impact on organizational performance outcomes. This study investigates the impact of organizational social capital (OSC) on employee creativity through the mediation role of knowledge sharing (KS) and moderation of work meaningfulness (WM).Design/methodology/approachThe authors base the analysis on employee-level data gathered via a cross-sectional survey designed for this study. The authors surveyed 217 employees of the pharmaceutical industry in Pakistan. The authors run a confirmatory factor analysis (CFA) and use structural equation modeling (SEM) and Hayes method to test the hypotheses.FindingsThe authors find that OSC positively affects employees’ willingness to share their knowledge with colleagues, which in turn has a positive effect on employee creativity (EC). The results also show that the relationship between social capital and knowledge sharing is moderated by work meaningfulness.Research limitations/implicationsThis study contributes to the IC in general and the SC literature in particular, by providing empirical evidence that shows how creativity could be a focal and pivotal performance outcome of organizational social capital through the moderated mediation roles of work meaningfulness and knowledge sharing.Originality/valueThe authors adopt the concept of SC from the organizational level to the individual level, examining how an individual's perception of organizational capital influences his or her creative behavior and exploring the role of KS and job meaningfulness (JM) in this relationship.
After the revolution – new chances for service research in a digital world
Authors: Kunz Werner H. , Walsh Gianfranco 
Published: July 2020

PurposeDigital media has revolutionized societies and changed forever how we do business. This paper aims to determine the current scope of service research in the area of digital media, identifying research gaps and introducing new research contributions to complement our knowledge of digital media.Design/methodology/approachBased on all service articles of the SERVSIG literature alert system from 2016 to 2019, a subset of digital media articles was identified and latent Dirichlet allocation (LDA) text-mining methods were used on the abstracts and titles of the articles for topic modeling of the field. Dominant research topics were identified and depicted in a two-dimensional space.FindingsThe study identifies eight distinct topic areas of digital media in service research and shows their relationship to each other in a two-dimensional space. A clear tendency in service research towards taking primarily a customer (versus business perspective) of digital media can be observed. Further, for some journals, a trend towards specialization on particular topics could be detected.Research limitations/implicationsThis article advocates for more digital media research with a stronger business perspective. Further, although particular new technologies are exciting to discuss, it seems that the importance of customer relationship topics in digital media is not reflected in the current digital media research as needed.Originality/valueThe article uses a quantitative–explorative approach to determine the current state of research in regard to digital media in services. The authors introduce 11 new studies that aim to close the knowledge gap in critical areas of digital media.
Connecting formal and informal workplace learning with teacher proactivity: a proactive motivation perspective
Authors: Huang Xianhan , Lai Chun 
Published: July 2020

Purpose
It is vital in today’s society that teachers are proactively involved in educational change. Given that proactive motivation is a critical driver of proactivity, this study aims to investigate how teachers’ formal and informal workplace-learning experiences were connected with their proactive motivations to implement educational change.

Design/methodology/approach
The authors used a qualitative case study approach to describe the relationships between teachers’ formal and informal learning activities and their different proactive motivations. The authors collected data from 17 teachers via individual interviews and open-ended questionnaire and performed analyses using a continuous inductive and deductive coding process.

Findings
The authors found that informal teacher learning can trigger three types of proactive motivation, whereas formal teacher learning is mainly connected with the can do and energised to motivations. The authors also found that formal and informal learning complement and compete with each other in shaping the can do motivation. Moreover, the authors found that informal learning played the dominant role in the reason to motivation, whereas informal and formal learning were separately connected to the energised to motivation.

Practical implications
These findings indicate that greater attention must be paid to teachers’ informal workplace-learning experiences. Specifically, teachers’ informal learning experiences should be actively integrated into their formal workplace training to enhance their proactive motivation to educational change. Moreover, teachers’ learning preferences and teaching experience should be considered in the design of teacher-training programmes.

Originality/value
Based on the proactive motivation model of Parker et al. (2010), the authors have uncovered the mechanisms of workplace learning that drive teacher proactivity. The authors have examined the relationship between teachers’ formal and informal workplace-learning and proactive teaching. The findings will assist policymakers and administrators to identify effective means of motivating teachers to engage in workplace learning.
Trade policy space and foreign direct investment inflows
Authors: Gnangnon Sena Kimm 
Published: July 2020

Purpose
This study aims to use a quantitative measure of trade policy space to investigate empirically whether trade policy space influences foreign direct investment (FDI) flows to countries.

Design/methodology/approach
The empirical analysis covers an unbalanced panel data set of 158 countries, over the period 1995–2015 and uses the two-step system generalized methods of moments approach.

Findings
The results suggest that the impact of trade policy space on FDI inflows is positive and increases as countries enjoy greater trade policy space. Furthermore, advanced economies tend to experience a higher positive impact of trade policy space on FDI inflows than less advanced economies.

Research limitations/implications
These findings highlight the relevance of trade policy space for countries’ FDI inflows.

Practical implications
The analysis shows that non-trade related constraints to trade policy could reduce trade policy space and adversely influence FDI inflows, which are critical for countries’ economic growth and development.

Originality/value
To the best of the knowledge, this topic has not been addressed in the literature.
Association between periodontitis and hyperlipidaemia: A systematic review and meta‐analysis
Authors: Xu Jing , Duan Xiaoqi 
Published: July 2020

AbstractTo date, it has been reported that periodontitis (PD) may be associated with hyperlipidaemia in clinical practice. However, data on this issue are inconsistent and controversial. The purpose of this meta‐analysis was to identify the association between PD and hyperlipidaemia. Here, 21 case‐control and eight cross‐sectional studies on PD and hyperlipidaemia were included in the random‐effects meta‐analysis, involving 2060 patients with PD and 2776 healthy controls (HC). Meta‐analysis showed that serum triglyceride (TG) and total cholesterol (TC) levels in the PD group were significantly higher than those in the HC group [TG, weighted mean difference (WMD) = 19.4 mg/dL, 95% confidence interval (CI) 13.3–25.5 mg/dL, P = .000; TC, WMD = 15.4 mg/dL, 95%CI 10.2–20.6 mg/dL, P = .000]. Subgroup analysis stratified by study design validated that PD was associated with higher serum TG and TC levels. In addition, compared with the HC group, serum low‐density lipoprotein (LDL) in patients with PD showed a markedly higher level (WMD = 11.7 mg/dL, 95% CI 8.3–15.0 mg/dL, P = .000), whereas serum high‐density lipoprotein (HDL) in PD group exhibited a significantly lower level (WMD = −4.5 mg/dL, 95%CI −6.4 – −2.7 mg/dL, P = .000). Finally, no significant publication bias was observed and sensitivity analysis also confirmed the stability of our meta‐analyses. In conclusion, the accumulated evidence suggests that PD is indeed associated with hyperlipidaemia in humans. More interventions for lowering lipids or increasing HDL may benefit the patients with PD, which need be further investigated in prospective clinical trials.
Development of a single nucleotide polymorphism array for population genomic studies in four European pine species

Published: July 2020

AbstractPines are some of the most ecologically and economically important tree species in the world, and many have enormous natural distributions or have been extensively planted. However, a lack of rapid genotyping capability is hampering progress in understanding the molecular basis of genetic variation in these species. Here, we deliver an efficient tool for genotyping thousands of single nucleotide polymorphism (SNP) markers across the genome that can be applied to genetic studies in pines. Polymorphisms from resequenced candidate genes and transcriptome sequences of P. sylvestris, P. mugo, P. uncinata, P. uliginosa and P. radiata were used to design a 49,829 SNP array (Axiom_PineGAP, Thermo Fisher). Over a third (34.68%) of the unigenes identified from the P. sylvestris transcriptome were represented on the array, which was used to screen samples of four pine species. The conversion rate for the array on all samples was 42% (N = 20,795 SNPs) and was similar for SNPs sourced from resequenced candidate gene and transcriptome sequences. The broad representation of gene ontology terms by unigenes containing converted SNPs reflected their coverage across the full transcriptome. Over a quarter of successfully converted SNPs were polymorphic among all species, and the data were successful in discriminating among the species and some individual populations. The SNP array provides a valuable new tool to advance genetic studies in these species and demonstrates the effectiveness of the technology for rapid genotyping in species with large and complex genomes.
Soil seedbank: Old methods for new challenges in agroecology?

Published: July 2020

AbstractThe weed soil seedbank is of interest in agroecosystems as a major source of weed infestation in fields and as a reservoir of plant and seed‐feeder diversity. A seedbank is a characteristic of annual plants and has been the focus of numerous studies, as it reflects the past aboveground vegetation and is the reservoir of the future vegetation. Therefore, it potentially can be used to evaluate the past, present and future annual weed communities. The goal of this paper was to provide guidelines to help researchers to do a weed seedbank survey. Through a qualitative review of 60 weed seedbank articles, we investigate why and how the seedbank has been studied in agronomy. It shows that seedbank studies have been performed to address the following four major objectives: (a) the assessment of weed management practices on weed communities; (b) the relationship between seedbank and aboveground vegetation; (c) the study of composition and diversity of seedbank in a given area; and, (d) the quantification of seedbank as a food resource for wildlife. Because the analysis highlighted a wide range of methodologies to estimate the seedbank, we critically reviewed them. We show that the selected methodology strongly affects the seedbank estimate. Nevertheless, in our sample of research articles, the analysis revealed that the choice of the methodology was not always justified in terms of achieving a particular scientific goal, but was often determined by the resources available for the experiment (e.g., workload). While studying the soil seedbank remains of interest for scientists (proved by the amount of recent publications), it is time consuming and requires considerable botanical skill. Innovative methods of estimation are scarce and novel methodological developments are needed to increase the quality and reliability of the data obtained.
Heightened Exploratory Behavior Following Chronic Excessive Ethanol Drinking: Mediation by Neurotensin Receptor Type 2 in the Anterior Paraventricular Thalamus
Authors: Pandey Surya , Barson Jessica R. 
Published: July 2020

BackgroundChronic, excessive alcohol drinkers, even without dependence, can exhibit changes in behavior and neurochemical systems. Identifying these changes and their relationship with one another could provide novel avenues for the prevention and treatment of alcohol use disorder. We recently demonstrated, in rats, that neurotensin (NTS) in the paraventricular thalamus (PVT) regulates excessive ethanol (EtOH) drinking. Here, we investigate the effects of chronic EtOH drinking on the PVT‐NTS system and its contribution to EtOH‐induced behavioral changes.MethodsWe gave adult male Long‐Evans rats 20% EtOH under the intermittent access 2‐bottle‐choice paradigm or maintained them on chow and water for up to 11 weeks. Prior to EtOH exposure and following several weeks of access, during acute abstinence, we tested these groups for multiple behaviors. In the 12th week, during acute abstinence, we examined gene expression and peptide levels of NTS and its receptors in the anterior and posterior subregions of the PVT. Finally, in chronic EtOH drinkers, during acute abstinence, we microinjected the NTS receptor type 2 (NTS2R) agonist, JMV‐431, in the anterior PVT (aPVT) and examined subsequent EtOH intake and behavior.ResultsFollowing chronic intermittent EtOH access, rats were classified by cluster analysis as high or low EtOH drinkers. High EtOH drinkers spent more time in the light chamber of a light–dark box and open arms of an elevated plus maze and entered fewer familiar holes in a hole‐board apparatus. These differences were absent prior to EtOH exposure but were detectable as early as 4 weeks into drinking. Time in the light chamber following chronic drinking also predicted level of subsequent drinking. High EtOH drinkers also showed elevated protein levels of NTS2R in the aPVT, and pharmacological stimulation of aPVT NTS2R in low drinkers mimicked the increased time spent in the light chamber that was observed in high drinkers.ConclusionsOur findings suggest that chronic, excessive, but not lower level, EtOH drinking induces heightened or flexible exploratory behavior, which predicts future EtOH drinking and is partly mediated by elevated NTS2R signaling in the aPVT. These EtOH‐induced alterations represent adaptations that could perpetuate excessive drinking and lead to the development of EtOH dependence.

BackgroundControversy exists regarding the way alcohol use is associated with vascular structure and arterial stiffness parameters. The purpose of this study is to evaluate the association between alcohol consumption with vascular structure and arterial stiffness in an adult population.MethodsWe conducted a cross‐sectional study. Five hundred and one participants were recruited by random sampling from an urban population of 43,946 individuals aged 35 to 75 years, assigned from 5 healthcare centers located in Salamanca, Spain. This was a subanalysis of the EVA study. Arterial stiffness was assessed by measuring cardio‐ankle vascular index (CAVI) and brachial‐ankle pulse wave velocity (ba‐PWV) with the VaSera VS‐1500® device, and carotid‐femoral pulse wave velocity (cf‐PWV) with the Sphygmocor®. Vascular structure was evaluated by measuring the carotid intima–media thickness (c‐IMT) with a Sonosite Micromax® ultrasound. Alcohol consumption was calculated using a standardized questionnaire and quantified in g/wk.ResultsIn the multiple regression analysis adjusted for sex, age, smoking status, and systolic blood pressure, the c‐IMT and cf‐PWV values of individuals drinking > 70 g/wk were higher than those of the reference group (nondrinkers) by 0.02 mm (p = 0.030) and 0.42 m/s (p = 0.021), respectively. The association between alcohol consumption with vascular structure and arterial stiffness only attains statistical significance for cf‐PWV (p = 0.039) and c‐IMT (p = 0.019), showing an association which suggests a J‐shaped association. This association was not statistically significant for ba‐PWV and CAVI (p = 0.446 and p = 0.141, respectively), although a similar trend was observed with ba‐PWV.ConclusionsThe results of this study suggest that heavy alcohol consumption (>70 g/wk) is associated with increased c‐IMT and cf‐PWV. Moreover, we found a J‐shaped association between alcohol consumption and c‐IMT and cf‐PWV values as markers of vascular structure and arterial stiffness, with no association with ba‐PWV and CAVI being observed.

Published: July 2020

AbstractAimTo evaluate oral health outcomes and early oral health promotion of children in a Swedish, parental support programme conducted in a collaboration between Child Health Services and Social Services.MethodsThe intervention offered first‐time parents six home visits from a paediatric nurse and a parental advisor with Social Services. On the fourth visit (infant age 6‐8 months), parents received a toothbrush and fluoride toothpaste from non‐dental staff. Twice, at child ages 18 and 36 months, a dentist used the International Caries Detection and Assessment System to record caries and conducted a structured interview with the parents on oral health habits. The intervention group (n = 72) was compared to a reference group (n = 100) from the standard child healthcare programme, which included one home visit.ResultsSignificantly, caries prevalence was lower and tooth brushing habits more consistent in the intervention group compared to the reference group in the standard child health programme. The difference was most pronounced at 18 months and had decreased at the 36‐month follow‐up.ConclusionThe extended postnatal home visiting programme had a positive impact on oral health. Early oral health promotion delivered by non‐dental professionals could be a beneficial approach to early caries prevention.
