Microstructural meal pattern analysis reveals that nicotine is a potent anti-anorectic drug despite producing long-term anorexigenic effects
Authors: Shankar Kokila , Ambroggi Frederic , George Olivier 
Published: February 2020

AbstractNicotine consumption in both human and animal studies has been strongly associated with changes in feeding-related behaviors and metabolism. The current dogma is that chronic nicotine decreases food intake and increases metabolism, leading to lower body weight. However, the effect of acute nicotine intake on feeding is unclear. The present study employed microstructural and macrostructural behavioral analyses to elucidate changes in feeding behavior in animals that intravenously self-administered nicotine. At the microstructural level (seconds to minutes), nicotine increased feeding and drinking behavior during the first 5 minutes after nicotine self-administration. This effect was also observed in animals that passively received nicotine, but the effect was not observed in animals that self-administered saline or passively received saline. At the macrostructural level (hours to days), nicotine decreased body weight gain, decreased feeding, and was associated with increases in feeding and body weight gain during abstinence. These results suggest that nicotine first produces anti-anorectic effects before producing long-term anorexigenic effects. These results challenge the notion that nicotine is an anorexigenic drug and paradoxically suggest that the anorexigenic effects of nicotine may be a long-term consequence of acute anti-anorectic effects of nicotine.
Bacterial Growth Stimulation and Antifungal Effects Of The Essential-oil-less-extracts Of The Food SpiceDysphania ambrosioides
Authors: Nitsch-Velásquez Lucía 
Published: February 2020

1AbstractD. ambrosioidesleaves (DaL) are utilized as food spice. DaL infusion is utilized as antihelminthic in traditional medicine, the extracted essential oil (EO) has been repurposed as biopesticide,in vitroactivities include nematocidal and phytotoxic activities by hydrophillic compounds from leaves and the roots. As Da might be a good candidate for circular economy, more potential applications of the essential–oil–less–Da extracts were pursued by applying green chemistry based extraction methods.DaL extracts were prepared by the autoclave method for the sterile–essential–oil–less aqueous extract (SALAEL–Da), butanol fractionating for saponins extraction (SAP) and ethanol boiling method for the saponin–free extract (EtOH–Da). Their effects over clinical isolates of fungi (Candida albicans/ CA), gram–negative bacteria (Erwinia carotovora/ ErC) and –positive (Methicillin resistantStaphylococcus aureusUSA 300 / MRSA–USA–300). were explored.The raw extracts stimulated the bacterial growth of all strains in the pre-screening phase.SALAEL-DaL (at 25 mg/mL) estimulated ErC growth, reducint its doubling time by 35%, microdilutions of EtOH-DaL (at 180 mg/mL) stimulated the growth of MRSA–USA–300 even in the GEN presence at sub-lethal concentrations (MICGEN=1.75µg/mL). SALAEL-Da (at 137 mg/mL) inhibited the growth of CA in agar dilutions, and its fraction SAP showed a moderated fungistatic effect at 100 mg/mL in disk diffusion pre-screening tests. SAP fraction may partially account for the observed antifungal activity. The essential–oil–less–Da aqueous extracts analyzed contained bacterial growth stimulating and antifungal components. Further investigation may lead to commercial opportunities for probiotics and antifungals.2ImportanceThe leaves ofD. ambrosioides(Da) are utilized as food spice and its infusion as antihelminthic in Latin American folk medicine, with a wide variety ofin vitrobioactivities reported. The most studied is Da essential oil (Da–EO) and has been repurposed as insect repellent and pesticide. Which would leave the extracted plant material as a potential raw material for other products. Additionally, Da could be an interesting candidate tobe produced at high–scale in rural communities. The ecofriendly extraction processes yielded an aqueous extract (free of the EO) that enhances the bacterial growth rate of two bacterial strains, which can eventually be useful in the probiotics industry. This extract also inhibited the growth of the opportunistic fungiCandida albicans, becoming a potential source of new antifungals. Further investigation may lead to a circular economy of the agroindustry aroundD. ambrosioides, probiotics and antifungals, among others.
Accommodation sharing: a look beyond Airbnb’s literature
Authors: Medina-Hernandez Vivian Constanza , Marine-Roig Estela , Ferrer-Rosell Berta 
Published: February 2020

Purpose
Airbnb is the peer-to-peer (P2P) accommodation platform that has attracted researchers’ attention during the past decade. The purpose of this paper attempts to illustrate the scarce research on P2P accommodation platforms other than Airbnb and to highlight the research gaps concerning these platforms.

Design/methodology/approach
This study starts by presenting a literature review on Airbnb based on several review papers about P2P accommodation sharing and conducts a quantitative comparative analysis between existing literature on Airbnb and other P2P accommodation platforms in Web of Science (WoS) using a keyword search.

Findings
Findings suggest that the literature regarding P2P accommodation platforms other than Airbnb is limited and that little is known about their possible impact on the collaborative tourism ecosystem. The analysis also suggests further research on P2P accommodation platforms to move on from an Airbnb-centric view and include other types of P2P accommodation platforms.

Originality/value
This paper compares the most common topics studied regarding Airbnb and other P2P accommodation platforms, highlighting the existence of other for-profit and non-profit accommodation platforms. It proposes new lines of research on different types of platforms such as the niche P2P accommodation platforms.
Prioritising theme park service quality in Islamic contexts: an analytic hierarchy process approach
Authors: Lari Lamya , Jabeen Fauzia , Iyanna Shilpa 
Published: February 2020

Purpose
This study aims to develop a framework to identify, categorise and prioritise the dimensions of service quality in theme parks in an Islamic cultural context.

Design/methodology/approach
An extensive literature review was conducted to identify service quality dimensions in theme parks in an Islamic cultural context, and a survey tool was used to explore visitors’ opinions of the most important dimensions and sub-dimensions. An analytic hierarchy process was used to prioritise the main criteria and sub-criteria of dimensions of theme park service quality in the United Arab Emirates (UAE). The study identified four main criteria and 24 sub-criteria of service quality for the theme park industry from an Islamic perspective.

Findings
Consumables quality and physical environment quality were the top priorities under the main criteria. Availability of halal food was the most important sub-criteria of service quality in theme parks in the UAE, followed by price of food and beverages and staff attitude and behaviour in equal second place, and then quality of food and beverages and quality of facilities, again with equal scores.

Research limitations/implications
The study focused on tourists visiting an emerging country, and the results therefore cannot be generalised to other cultural contexts. This study has developed a comprehensive model of theme park service quality using a hierarchical method. This included both general and Islamic service quality dimensions. This study, therefore, contributes to the “Islamic tourism” literature by identifying the importance of Islamic attributes in evaluating service quality of theme parks in Islamic countries.

Practical implications
The outcome of the study will provide local and international theme parks with explicit ideas about the service quality dimensions that are important in an Islamic cultural context. This will help them to prioritise the critical service quality dimensions, and eventually contribute to the successful management of theme parks.

Originality/value
This study offers new insights into the dimensions of service quality of theme parks in an Islamic cultural context.
Optimal planning of renewable energy systems for power loss reduction in transmission expansion planning
Authors: Gbadamosi Saheed Lekan , Nwulu Nnamdi I. 
Published: February 2020

Purpose
The purpose of this study is to address the efficiency of power losses representation while still reducing the computational burden of an optimal power flow (OPF) model in transmission expansion planning (TEP) studies.

Design/methodology/approach
A modified TEP model is formulated with inclusions of linearized approximation of power losses for a large-scale power system with renewable energy sources. The multi-objectives function determines the effect of transmission line losses on the optimal power generation dispatch in the power system with and without inclusion of renewable energy sources with emphasis on minimizing the investment and operation costs, emission and the power losses.

Findings
This study investigates the impact of renewable energy sources on system operating characteristics such as transmission power losses and voltage profile. Sensitivity analysis of the performance for the developed deterministic quadratic programming models was analyzed based on optimal generated power and losses on the system.

Research limitations/implications
In the future, a comparison of the alternating current OPF and direct current (DC) OPF models based on the proposed mathematical formulations can be carried out to determine the efficiency and reduction of computation process of the two models.

Practical implications
This paper proposed an accurate way of computing transmission losses in DC OPF for a TEP context with a view of achieving a minimal computation time.

Originality/value
This paper addresses the following objectives: develop a modified DC OPF with a linearized approximation of power losses in TEP problem with large integration of RES. Investigate the impact of RES on system operating characteristics such as transmission power losses and voltage profile.

Authors: El Araby Mohamed Awad , Ayaad Noor el Dien Salem 
Published: February 2020

Purpose
The main target of the study represented in developing a proposed Quantitative Model for the purpose of measuring the administrative performance of public governmental organizations, taking into account the validity of the model for many different contexts in practice through governmental sector.

Design/methodology/approach
Depending on statistical approach, both authors tried to handle this issue through assessing institutional performance in the state owned units on many levels starting from individual level (HR and leaders), sub-units, organization level, then deriving an aggregated formula for assessing general institutional performance of the whole public body in one state, depending on reviewing some of concerned literatures.

Findings
The authors could already formulate some proposed criteria for assessing and measuring institutional performance on three different levels.

Originality/value
Although the topic is considered one of the most complicated areas of institutional reform trends, the idea remains very vital as a step forward to improving public policy implementation in the governmental sector, besides that it is correlated to institutional capacity building process in practice.
Mapping terrorist groups using network analysis: Egypt case study
Authors: Tawadros Amira S.N. 
Published: February 2020

Purpose
The purpose of this study is twofold; first, it aims to understand the underlying dynamics of the organizations behind the terrorist attacks, and second, to investigate the dynamics of terrorist organizations in relation to one another to detect whether there exist shared patterns of terror between different organizations.

Design/methodology/approach
To achieve this purpose, the researcher proposes a computational algorithm that extracts data from global terrorism database (GTD); calculates similarity indices between different terrorist groups; generates a network data file from the calculated indices; and apply network analysis techniques to the extracted data. The proposed algorithm includes applying SQL database codes for data extraction, building a tailored C# computer software to calculate similarity indices and generate similarity networks and using GEPHI software to visualize the generated network and calculate network metrics and measures.

Findings
Applying the proposed algorithm to Egypt, the results reveal different shared patterns of terror among different terrorist groups. This helps us in creating a terror landscape for terrorist groups playing in Egypt.

Originality/value
The importance of the study lies in that it proposes a new algorithm that combines network analysis with other data-manipulation techniques to generate a network of similar terror groups.

Authors: Allely Clare Sarah 
Published: February 2020

PurposeThere remains a lack of knowledge surrounding paraphilic or deviant arousal sexual behaviours in individuals with Autism spectrum disorder (ASD) (Kellaher, 2015). The purpose of this paper is to explore the literature for any empirical study, case study or discussion/review paper surrounding individuals with ASD and zoophilia or bestiality.Design/methodology/approachA systematic PRISMA review was conducted.FindingsThis systematic review highlighted only a small number of papers, which have looked at zoophilia or bestiality in individuals with ASD. Only one article was identified as being relevant in the present review, three further articles included a description of a case involving someone with ASD who engaged in zoophilia or bestiality and another paper, although not the focus of the study, found one person with Asperger’s disorder who had several paraphilias including olfactophilia, podophilia and zoophilia in a sample of 20 institutionalised, male adolescents and young adults with Autistic disorder and borderline/mild mental retardation. All the case studies clearly highlight some of the ASD symptomology that can contribute to engaging in bestiality or zoophilia.Practical implicationsIt is important that individuals with ASD have access to appropriate and timely sex education and that parents are supported by healthcare professionals to engage with their children with ASD in such interactions across the autism spectrum irrespective of the parent’s expectations.Originality/valueTo the author’s knowledge, this is the first review of ASD in relation to bestiality and zoophilia.

The rise of micromobilities at tourism destinations
Authors: Davies Nick , Blazejewski Luke , Sherriff Graeme 
Published: February 2020

Purpose
This paper aims to identify the need for research that focuses on micromobilities at tourist destinations, charting their recent expansion and exploring development challenges.

Design/methodology/approach
This discussion draws together recent evidence and studies that are directly and indirectly related to the rise of micromobilities. It identifies and critically analyses the trend going forward, its potential benefits and challenges, and offers several areas of future study.

Findings
Micromobilities relates to a new umbrella term that includes, but is not limited to, walking, cycling (both existing modes), e-bikes and e-scooters (new modes). The proliferation of new micro-modes in urban zones at destinations can be viewed positively in terms of their potential to increase sustainable urban mobility and therefore destination attractiveness; but also negatively in terms of potential space issues, accessibility and sustainable implementation. Destination developers and stakeholders should therefore consider carefully how to successfully integrate micromobilities into sustainable transport systems.

Originality/value
This paper addresses a trend that is extremely prominent at many destinations but largely absent from academic study and that is also being described by commentators as key to sustainable futures at destinations.

Authors: Blanchet Cyril , Fabry Nathalie 
Published: February 2020

Purpose
This paper aims to anticipate the influence of new cinematographic and television operators on the attractiveness of tourist destinations.

Design/methodology/approach
The methodology developed is two-fold: first, long-haul observation of the sector, and second, a state of the literature on the topic.

Findings
These platforms reshape the distribution of audiovisual content and influence consumer behavior. Through the detailed knowledge of users (user data, recommendation algorithm), the platforms have important information at their disposal to build future tourism trends.

Originality/value
In the continuity of research in film tourism, the authors question the impact of platforms that are now emerging as significant operators in the distribution and creation of audiovisual content.
Synthesis and characterization of UV-cured epoxy acrylate resin with cyclic methacrylate as diluents
Authors: Guo Yuyue , Lin Shudong 
Published: February 2020

PurposeThis paper aims to investigate the effects on material performance in the epoxy acrylate resin system owing to the existence of the different ring of the cyclic methacrylate. In this paper, cyclic methacrylate as diluents was added into epoxy acrylate (EA) resin by ultraviolet (UV)-cured polymerization to investigate the effects on material performance owing to the existence of the different rings.Design/methodology/approachEA and 1-adamantyl methacrylate were synthesized by traditional methods according to previous papers, respectively. After adding different cyclic methacrylate as diluents to the EA oligomers, the system was exposed to the UV-light for polymerization.FindingsThe hydrophobic properties of the cured materials were increased slightly because of the alkyl groups from the methacrylate. The thermal stabilities and mechanical properties of the resins were enhanced by the cyclic diluents with the hard segments. Meanwhile, the crosslink density of the polymer decreased with the bulky group like adamantly owing to its huge structure.Research limitations/implicationsThe cyclic methacrylates were introduced into EA oligomers for decreasing the viscosity and increasing the materials performances, which could be recognized as new diluents applied in UV-cued polymerization.Originality/valueThe results of this study will be conducive to fabricate EA resins possessed with high thermal stabilities and mechanical properties by convenient UV-cured polymerization.
Who can realize the “spot value” of corporate social responsibility?
Authors: Wang Shiyu , Zhang Yan , Wang Guanzhen , Chen Zhibin 
Published: February 2020

Purpose
This paper answers, in the Chinese stock market, who can realize the “spot value” of corporate social responsibility (CSR).

Design/methodology/approach
The authors use event-study to build the research framework. Using CSR report content analysis, the authors measure the specification level of CSR disclosure. Applying the Baidu index, the authors mine Chinese investors’ profiles data to investigate retail investor heterogeneity closely.

Findings
The authors find strong evidence that the measure captures a behavioral bias in CSR pricing: firms that choose to disclose CSR report experience positive abnormal return more among retail investors than institutional investors, more among young investors than older, but no difference between female and male investors.

Practical implications
For Chinese public firms, the authors give them evidence that they can realize positive abnormal returns by applying certain CSR disclosure strategies. For Chinese investors, especially retail investors and youths, the authors ask them to rethink whether their positive evaluation of CSR is a rational trade-off choice or whether they are fooled by the “hedging mask” and “attention-grabbing.”

Social implications
The findings can give some suggestions to regulators: encouraging voluntary disclosure and reducing mandatory disclosure can drive enterprises to engage in more CSR activities because the voluntarily CSR disclosure can realize both long-term value and “spot value.” Complementarily, a more rigorous CSR report auditing regulation can suppress the “greenwash” by increasing the “lying cost.”

Originality/value
Using behavioral finance theory, the authors connect the gap between neoclassical research on the “U-shaped” value realization of CSR and the increasing voluntary CSR disclosure in the Chinese market. The authors find that heuristic reason and emotionality orientation results in the Chinese “CSR-friendly” market.
Traceability matters
Authors: Hinkes Cordula , Peter Günter 
Published: February 2020

Purpose
Sustainability certification of agricultural commodities might be one measure to ensure deforestation-free supply chains. The purpose of this paper is to add to previous assessments of soy certification systems with respect to “zero deforestation” criteria by focusing on the aspect of traceability.

Design/methodology/approach
A conceptual framework for assessing certification systems is proposed based on a literature review. This concept is applied to 16 soy certification systems, considering previous studies and available chain-of-custody certification options.

Findings
Among the sample, five certification systems may contribute to ensuring deforestation-free soy supply chains, as they have relatively high “zero deforestation” and assurance requirements and support at least segregation. Other chain-of-custody systems are insufficient in terms of traceability, but still dominate the market.

Research limitations/implications
The assessment considers only certification systems that have been benchmarked according to criteria developed by the European feed industry. Regular updates and further assessments of certification systems for other commodities are recommended.

Practical implications
Supply chain actors and policymakers are informed about certification systems that may ensure deforestation-free sourcing. However, different factors influence the implementation of zero deforestation commitments, such as adverse effects, economic trade-offs and new certification and traceability concepts.

Social implications
The implementation of deforestation-free supply chains should contribute to achieving sustainable development goals. Potential adverse social effects need to be considered.

Originality/value
This study focuses on the so far rather neglected but essential aspect of traceability, which is required for ensuring deforestation-free sourcing along the whole supply chain.
