Corruption and international trade: a comprehensive analysis with gravity
Authors: Gil-Pareja Salvador , Llorca-Vivero Rafael , Martínez-Serrano José Antonio 
Published: October 2019

PurposeThe purpose of this paper is to analyze the impact of corruption on trade.Design/methodology/approachThe authors estimate gravity equations with the last econometric advances on a wide sample of countries and years using three different measures of corruption. Two of them belong to the so-called perception-based indexes and the third is derived from a structural model that takes into account the causes and indicators of corruption across countries.FindingsA negative effect of corruption on trade appears with perceptions, but it is not widespread. However, the authors find sensible evidence of the “grease the wheels” view with the structural index if low and middle income countries are implicated. Additionally, when using this measure, differences in corruption levels negatively impact trade. Both results are in line with expectations.Originality/valueMoreover, membership in regional trade agreements does not seem to significantly alter these results.
Education and economic growth: an empirical analysis of nonlinearities
Authors: Marquez-Ramos Laura , Mourelle Estefanía 
Published: October 2019

PurposeMight a country’s economic growth performance differ depending on the evolution of its human capital? This paper aims to consider education as a channel for human capital improvement and then for economic growth. The authors hypothesize the existence of a threshold for education, after which point the characteristics of economic growth change.Design/methodology/approachTo address this question, the authors turn from a linear framework to a nonlinear one by applying smooth transition specifications.FindingsThis empirical analysis for Spain points to the existence of nonlinearities in the relationship between education and economic growth at country level, for both secondary and tertiary education. Next, as different patterns emerge in different regions, the authors provide a regional analysis for a number of representative Spanish regions. The results show that both secondary and tertiary education matter for economic growth and that nonlinearities in this relationship should be taken into account.Practical implicationsWhat is learnt from using Smooth Transition Regression models for the education-economic growth link is that the educational level of the population can be understood as a source of nonlinearities in the economic activity of a country (and of a region). Thus, depending on national and regional educational levels, economic growth behaves differently.Originality/valueAlthough the importance of nonlinearities has been identified, linearity is usually assumed in this field of the literature. This paper calls into question the linearity assumption by using time series techniques for 1971-2013 in Spain, an OECD country, and testing whether the results at country level hold for different regions within Spain as a robustness check.
Affiliation to alcoholics anonymous or narcotics anonymous among patients attending an English specialist addiction service
Authors: Day Edward , Kirberg Sabrina , Metrebian Nicola 
Published: October 2019

Purpose
Attendance at alcoholics anonymous (AA) or narcotics anonymous (NA) meetings and affiliation with the fellowship has potential benefits for people with alcohol or drug use disorders. This effect is present whether or not the individual attends professional treatment services, but the two process can have a synergistic effect. Limited information exists about the extent to which people attending UK specialist treatment services also attend AA/NA and their views about such attendance. The paper aims to discuss these issues.

Design/methodology/approach
A cross-sectional survey of 200 consecutive attendees at the specialist treatment service in an English region was conducted between January and April 2018. A measure of past attendance and affiliation with AA/NA (AAAS) and a scale designed to quantify future readiness to attend (Survey of Readiness for Alcoholics Anonymous Participation) were administered and anonymously linked to data supplied to the National Drug Treatment Monitoring Service (NDTMS).

Findings
A minority of the sample had ever attended an AA meeting (31 per cent, n=59) or an NA meeting (41 per cent, n=79), and only 14 per cent (n=27) and 24 per cent (n=45) had attended an AA or NA meeting, respectively, in the past year. Only two variables significantly predicted level of readiness to attend AA or NA in a regression model: attended more AA/NA meetings in the past (ß=0.149, p=0.036) and previous level of participation (AAAS score) (ß=0.409, p < 0.001).

Practical implications
A significant proportion of attendees of a specialist drug and alcohol treatment service had never attended AA/NA, despite many positive views about their potential benefits. Given the established benefits of attending AA/NA meetings and participating in the AA or NA fellowship, these results suggest that professional treatment services should do more to explain the process and challenge preconceived ideas about how they operate.

Originality/value
The authors are not aware of any published research that captures the rates of attendance of and participation in both AA and NA groups in a UK-based community treatment sample. These results may therefore provide a baseline for evaluating the impact of interventions to increase attendance/participation, and also provide some insight into the potential barriers to attendance in this population.
Do medical cannabis growers attempt to produce cannabis with different cannabinoid concentrations than recreational growers?
Authors: Sznitman Sharon R. , Barratt Monica J. , Decorte Tom , Hakkarainen Pekka , Lenton Simon , Potter Gary , Werse Bernd , Wilkins Chris 
Published: October 2019

Purpose
It is conceivable that cannabis cultivators who grow for medical purposes aim to improve the therapeutic index of their cannabis by attempting to produce particular concentrations of CBD and/or THC. The purpose of this paper is to examine whether small-scale medical cannabis growers differ from those growing for recreational reasons in terms of self-assessed concentrations of THC and CBD in the cannabis they grow.

Design/methodology/approach
Data collection was conducted online from a convenience sample of 268 cannabis growers visiting a popular Israeli cannabis internet forum. χ2 and Kruskal–Wallis H were used to test bivariate associations between medical and recreational cannabis cultivators in terms of self-assessed cannabinoid concentrations.

Findings
In total, 40 percent of cannabis growers reported that they grow for medical purposes. Medical cannabis growers were more likely to report that they thought they knew the cannabinoid concentrations of the cannabis they grew and they reported higher self-assessed concentrations of THC, but not CBD.

Originality/value
Compared to recreational growers, medical cannabis growers are more likely to strive to be informed in terms of the content of their cannabis. Medical growers may also be attempting to grow more potent THC but not CBD cannabis.
Operations strategy of cloud-based firms: achieving firm growth in the Big Data era
Authors: Shou Yongyi , Zhao Xinyu , Chen Lujie 
Published: October 2019

PurposeCloud computing is a major enabling technology for Industry 4.0 and the Big Data era. However, cloud-based firms, who establish their businesses on cloud platforms, have received scant attention in the extant operations management (OM) literature. To narrow this gap, the purpose of this paper is to investigate cloud-based firms from an operations strategy perspective.Design/methodology/approachA two-phase multi-method approach was adopted. In the first phase, content analysis of 27 reports from cloud-based firms was conducted, aided by text mining keyword extraction. Two data-related operations capabilities were identified and hypotheses were posited regarding the relationships between data resources (DR), operations capabilities and firm growth (FG). In the second phase, a sample of 190 cloud-based firms was collected. Seemingly unrelated regression and bootstrapping method were employed to test the proposed hypotheses using the survey data.FindingsThe content analysis indicates data as a key resource and both data processing capability and data transformational capability as critical operations capabilities of cloud-based firms. FG is regarded as a top priority in the cloud context. The regression results indicate that DR and the two capabilities contribute to the growth of cloud-based firms. Moreover, a follow-up bootstrapping analysis reveals that the mediating effects of the two capabilities vary between different types of FG.Originality/valueTo the authors’ best knowledge, this is one of the first OM studies on cloud-based firms. This study extends the operations strategy literature by identifying and testing the key operations capabilities and priorities of cloud-based firms. It also provides insightful implications for industrial practitioners.

Published: October 2019

Purpose
The purpose of this paper is to investigate the magnetic properties and the ground state phase diagrams of the double perovskite La2NiMnO6 using the Monte Carlo simulations (MCS).

Design/methodology/approach
In this work, the authors propose a Hamiltonian modeling this compound, described by an Ising model, with different exchange coupling interactions J11, J12 and J22 between the only magnetic atoms Ni and Mn.

Findings
Starting with the ground state phase diagrams, the authors present and discuss the stable configurations in different physical parameter planes. On the other hand, the authors present the investigation of the magnetic properties and the magnetization behaviors of the magnetic susceptibilities, as a function of temperature, crystal field, the exchange coupling interactions and the Zeeman energy. To complete this study, the authors illustrate the dependency of the total magnetizations for the hysteresis loops of the double perovskite La2NiMnO6 compound. This study is done for fixed values of temperature, the exchange coupling interactions and crystal field.

Originality/value
The authors modeled the different physical parameters of the double perovskite La2NiMnO with a Hamiltonian describing the system. At T=0K, the authors discussed the ground state phase diagrams of different physical parameters planes. For non-null temperature values, the authors studied the magnetic behavior of the double perovskite La2NiMnO using MCS under the metropolis algorithm. The authors expect that the results of these simulations can provide some important keys for the experimental research and technology applications of the double perovskite La2NiMnO6 in the future.

Purpose
The purpose of this study is to explore a methodology for connecting microelectromechanical system sensors – i.e. inertial measurement unit (IMU) – to an Arduino-based microcontroller, using graphene-based conductive filament and flexible thermoplastic polyurethane (FTPU) filament and low-cost dual material extrusion technology.

Design/methodology/approach
A series of electrical tests were carried out to determine the maximum resistance the conductive paths may take to connect printed circuit boards (PCB). To select the most suitable printing material, three types of conductive filaments were examined. Then an experiment was carried out to find the best printing parameters in terms of printing speed, printing temperature and layer height to minimise resistivity. The size of the conductive path was also analysed. A final prototype was designed and printed according to optimised printing settings and maximum allowable resistances for each line and considering different geometries and printing strategies to reduce cross-contamination among paths.

Findings
For the Black Magic 3D conductive filament, the printing speed and layer height played a significant role regarding resistivity, while the printing temperature was not very important. The infill pattern of the conductive paths had to be aligned with the expected current path, while using air gaps between two adjacent paths resulted in the best approach to reducing cross-contamination. Moreover, the cross-section size of the conductive path did not affect the volume resistivity. When combined with FTPU filament constraints, the prototype yielded suitable electrical performance and printing quality when printed at a temperature of 220°C, speed of 20 mm/s and layer height of 0.2 mm.

Originality/value
This paper explores a systematic methodology for the additive manufacturing of commercial conductive material using low-cost extrusion technology to connect complex electronics when data transmission is a key feature.

Published: October 2019

AbstractMedicolegal disputes are increasing in practical medicine. Medications or procedures related to acne could lead to medical malpractice. This study analyzed medical litigation associated with acne in South Korea. Acne‐related judgments were searched using the Supreme Court of Korea’s Written Judgment Management System based on the keyword “acne”. Eleven cases were selected; eight cases were related to acne scar and three cases were related to acne. Treatment modalities such as peeling, laser treatment, photodynamic therapy and antibiotics resulted in lawsuits. Claimed sequelae of the treatments were hyperpigmentation, scar worsening, erythema, skin bumps and liver transplant. Eight cases were awarded to the plaintiff, and the others were dismissed. This study shows that various treatments for acne can cause medical disputes.
Ecological Gentrification in Response to Apocalyptic Narratives of Climate Change: The Production of an Immuno‐political Fantasy
Authors: Harper Earl T. 
Published: October 2019

AbstractAnxieties over the potential impacts of climate change, often framed in apocalyptic language, are having a profound, but little studied effect on the contemporary Western urbanscape. This article examines the ways in which current theorizations of ‘ecological gentrification’ express only half the process, describing how green space is used for social control, but not how ecology is used as a justification regime for such projects. As urbanites seek out housing and living practices that have a lower environmental impact, urban planners have responded by providing large‐scale regeneration of the urbanscape. With the demand for this housing increasing, questions of inequality, displacement and dispossession arise. I ask whether apocalyptic anxiety is being enrolled in the justification regimes of these projects to make them hard to resist at the planning and implementation stages. The article shows that, in capitalizing on collective anxiety surrounding an apocalyptic future, these projects depoliticize subjects by using the empty signifier, ‘Sustainability’, leading them into an immuno‐political relationship to the urbanscape. This leaves subjects feeling protected from both responsibility for, and the impacts of, climate change. Ultimately, this has the consequence of gentrification coupled with potentially worsening consumptive practices, rebound effects and the depoliticization of the environmentally conscious urbanite.

AbstractObjectivesDue to the instability of microRNAs, the applications of microRNA are currently limited. Thus, we utilized tetrahedral framework nucleic acids and a targeted microRNAs to form a stable nanocomposite to explore whether this nanocomposite can promote apoptosis of tumour cells.Materials and methodsIn our study, the survivin gene, which is expressed only in tumour cells and embryonic cells, was selected as the target gene; miRNA‐214‐3p, which can reduce the expression of survivin, was modified onto tetrahedral framework nucleic acid, thereby producing a reduction in the expression of survivin upon intracellular delivery and eventually leading to tumour cell apoptosis.ResultsBy comparing the stability of microRNAs with that of microRNA‐tetrahedral framework nucleic acid, we proved the superiority of this carrier system. The results of flow cytometry showed that after treated with this complex, the ratio of A549 cells in both late and early period of apoptosis in miRNA‐214‐3p‐tetrahedral framework nucleic acid group had doubled and the cell cycle in the G2‐M phase had declined. The decrease in the expression of anti‐apoptotic protein and the increase in the expression of pro‐apoptotic protein indicate that the ability of this complex to function in cells also makes it attractive as a new targeted therapy for cancer.ConclusionThe unique expression of survivin in tumour cells and embryonic cells makes microRNA‐tetrahedral framework nucleic acid a new targeted therapy. In addition, due to the functional diversity of microRNAs, this delivery system approach can be applied to a wide variety of fields, such as targeted therapy and tissue regeneration.
Translational Model‐Informed Dose Selection for a Human Positron Emission Tomography Imaging Study of JNJ‐54175446, a P2X7 Receptor Antagonist

Published: October 2019

Positron emission tomography (PET) provides useful information in target engagement or receptor occupancy in the brain for central nervous system (CNS) drug development, however, dose selection for human PET studies is challenging and largely empirical. Here, we describe a translational pharmacokinetic/pharmacodynamic (PK/PD) modeling work to inform dose selection for a human PET study of JNJ‐54175446, a CNS‐penetrating P2X7 receptor antagonist. Models were developed using data on monkey brain occupancy and plasma drug exposures from a monkey PET study and early human clinical studies that provided data on drug exposures and human ex vivo‐stimulated peripheral interleukin (IL)‐1β release. The observed plasma PK of JNJ‐54175446 in human was adequately described by a one‐compartment model with parallel zero‐order and first‐order absorption and first‐order elimination. An exposure‐occupancy model was extrapolated from monkey to human assuming a similar unbound potency (all other model parameters remained unchanged). This model was then used to simulate human brain occupancy to guide human PET study dose selection, together with the human population PK model. The corroboration of model predicted occupancy by the observed occupancy data from the human PET study supports the use of a monkey as a predictive model for human PET target engagement. Potency estimate for brain occupancy was generally comparable to that for the suppression of the provoked peripheral IL‐1β release ex vivo, indicating that blood IL‐1β release may be used as a surrogate of central occupancy for JNJ‐54175446. Translational PK/PD modeling approach could be used for selecting optimal doses for human PET and other clinical studies.
Salvation by good works? Offshoring, corporate philanthropy, and public attitudes toward trade policy
Authors: Kerner Andrew , Sumner Jane L. 
Published: October 2019

AbstractAmerican consumers are routinely reminded of the fact that the products sold by American companies are often manufactured abroad. We use a survey‐based priming experiment to explore whether and when those reminders depress Americans’ enthusiasm for free trade. We consider in particular that offshoring's effects on policy preferences may be linked to negative perceptions of the offshoring firm, such that portraying the offshoring firm in a positive light might mitigate that effect. We also consider that offshoring's effect may be exaggerated among individuals whose position in the labor market makes them especially sensitive to trade‐related labor market disruption. Our experiment suggests support for both propositions.

Published: October 2019

AbstractAimDetecting and diagnosing youth mental health issues can be challenging for General Practitioners (GPs) who are often the first to encounter them. One aim of this study was to understand the challenges GPs faced in identifying, treating and referring young people with mental health issues in Melbourne, Australia. A second aim was to identify gaps in GP knowledge and service provision in order to design a service and training program for GPs that addresses those gaps.MethodA representative sampling method was used to invite GPs in south‐east Melbourne to complete the study survey. Seventy‐seven GPs completed the questionnaire consisting of 10 questions in 3 sections.ResultsThe results showed that GPs who consulted with young people more often had greater levels of confidence in identifying and treating their mental health issues but not referring. Forty‐four percent identified the need for training in regards to youth mental health. GPs considered that the most effective care was provided in youth‐friendly spaces but tended to primarily refer young people to private providers.ConclusionGPs need access to ongoing professional development and education programs on youth mental health, in particular more severe issues such as psychosis. Specialist youth mental health services such as CYMHS/CAMHS and headspace can offer GPs support in managing mental health issues in young people. However, there is a need to strengthen the link between GPs and specialist youth mental health service. Stronger links between services will ensure young people have timely and increased access to treatment.
