Consumer preferences using the method BW Score: A study of Brazilian consumer's perception
Authors: Neumann da Cunha C. , Dewes H. , Araújo M.V. 
Published: October 2019

Purpose Identify the most important attributes used by consumers in Porto Alegre (Brazil) in the wine selection process. Originality/value: The behavior of the wine consumer is changing, since people have different wants and needs which are influenced by several factors. Among these factors, the attributes of the product are relevant to understanding the decision-making process of the consumer. Understanding such behavior is fundamental for the development of the market, since it is the consumer who determines what and how many products will be acquired. In this sense the research becomes relevant for a better understanding of the behavior of the wine consumer in the Brazilian market.Design/methodology/approach: A qualitative exploratory study through interviews with two experts in Porto Alegre (Brazil) to investigate the relevance of the attributes proposed in the literature review. The results reaffirmed the need to use 13 attributes. Later an online questionnaire was applied to 100 wine consumers. Therefore, in this work, a BIB (13, 4, 4, 1) was generated for further analysis using the BW score. As a complement, ANOVA was used to analyze the mean differences between attributes and segments. Findings: The results obtained showed that the most important attributes are related to the previous experience of the consumer with wine, gastronomic harmonization and recommendations.

Abstract
Background and study aims Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a novel endoscopic procedure designed to facilitate sustained luminal patency in patients with gastric outlet obstruction. The primary aim of this study was to evaluate the efficacy and safety of EUS-GE for treatment of gastric outlet obstruction.
Methods Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed through April 2019. Patients with benign and malignant gastric outlet obstruction were included. Measured outcomes included: immediate technical and clinical success as well as rate of serious adverse events (AEs). Heterogeneity was assessed with Cochran Q test and I
2 statistics. Publication bias was ascertained by funnel plot and Egger regression testing.
Results A total of five studies (n = 199 patients; 45.73 % male) were included in this study. Four retrospective studies and one prospective study were analyzed. Mean age of patients that underwent the EUS-GE procedure was 64.52 ± 1.37 years with a pooled mean follow-up period of 4.32 ± 1.65 months. In 21 % of patients (n = 43), gastric outlet obstruction was due to benign causes. Immediate technical success was 92.90 % (95 % CI; 88.26 – 95.79; I2 = 0.00 %) and reported in all studies. The clinical success rate of EUS-GE was 90.11 % (95 % CI; 84.64 – 93.44; I2 = 0.00 %). Serious AEs occurred in 5.61 % (95 % CI; 2.87 – 10.67; I2 = 1.67 %) of cases and were related to peritonitis, perforation, bleeding, and abdominal pain. Re-intervention rate was 11.43 % (95 % CI; 7.29 – 17.46; I2 = 17.38 %).
Conclusions EUS-GE appears to provide an effective and safe minimally invasive alternative for treatment of benign and malignant gastric outlet obstruction.
An Aristotelian interpretation of practical wisdom: the case of retirees
Authors: Massingham Peter 
Published: October 2019

AbstractThis paper aims to improve understanding of the concept of practical wisdom. The theoretical lens used is Aristotle’s practical rationality or ‘phronesis’. Researchers argue that practical wisdom should be used as an organising framework for professional knowledge. Aristotle believed that practical wisdom as the highest intellectual virtue. Phronesis is the complicated interactions between general (theory) and practical (judgement). The contribution of this paper is to discuss the properties of practical wisdom and how they interact based on an interpretation of retirees’ knowledge. The paper summarises in-depth face-to-face interviews with nine retirees, i.e., nine separate case studies. A structured interview guideline based on a conceptual framework derived from literature was used to examine the nature of retirees’ practical wisdom. People with wisdom make better decisions. Whereas episteme’s technical knowledge may address complicated tasks, techne’s wisdom enables people to resolve truly complex tasks. Techne provides personal judgement which enables the professional to judge their actions from an external and internal perspective. Knowing that others and the individual themselves are happy with the quality of their work creates a morality that enables an inner calm and personal satisfaction leading to eudaimonia (feeling happy about life). People with wisdom behave differently. Phronesis’s cognitive properties create awareness of the knowledge that may be trusted to be seen to be behaving normally or appropriately in the organisation. The global population is ageing. This has implications for future workforce planning as experience is lost and capability gaps emerge. Retires may represent a valuable source of knowledge to help address this gap. The results are limited to nine individual case studies and four disciplines. The findings provide exciting opportunities for further research. The conceptual models may be further investigated with retirees in other disciplines.

AbstractAttention Deficiency and Hyperactivity Disorder (ADHD), as a predictor of injuries in motorcyclists, affects the risky behavior. Since there was no pre-established conceptual model, this study aimed at exploring a conceptual model. Following this model, the Structural Equation Modeling (SEM) was utilized to find the predictors of Motorcycle Riding Behavior (MRB), as well as the mediators and moderators of ADHD-MRB relationship. In the current cross-sectional study, 340 motorcyclists in Bukan city, Iran, were recruited through a randomized cluster sampling. A simple conceptual model was explored and utilizing the goodness of fit indices in SEM, an optimal model was chosen. Then, utilizing 3-step hierarchical regressions and SEMs, the relationship between ADHD and MRB was assessed by modeling the possible mediators/moderators such as answering the cell phone and using the helmet. The results of hierarchical regression showed that answering the cell phone had both moderating and mediating effects on the relationship between ADHD (and the ASS subscale) with MRB. The final SEM, by introducing the mediating role of underlying variables, had a good fit on data (Normed Chi2 = < 5.0, RMSEA < 0.08, SRMR < 0.05, CFI and TLI > 0.90), wherein ADHD score (and the subscales) predicted the MRB score directly/indirectly (P < 0.05). A simple conceptual model was found to assess the mediating role of ADHD in motorcyclist risky behavior. Based upon the findings, training the techniques of and/or enforcement for controlling and improving riding behaviors and skills among ADHD motorcyclists, those who answer their cell phones while riding, un-experienced riders, and those who ride without wearing the helmet is strongly recommended.
Determinants of international price volatility transmissions: the role of self-sufficiency rates in wheat-importing countries
Authors: Guo Jin , Tanaka Tetsuji 
Published: October 2019

AbstractFrom the 1980s until the early 2000s, many developing governments adopted market liberalization policies due to relatively low agricultural prices and the implementation of structural programs by the IMF. Yet, a paradigm shift occurred with the emergence of the 2008 food crisis, which directed food-deficit governmental bodies to protectionist regimes supporting higher food self-sufficiency. Despite the importance of food autarky to shield domestic food markets, its effects have never been fully discussed in a formalized econometric framework. This article analyses wheat price volatility transmissions from global to local markets in 10 wheat importing countries, identifying the causality with conditional correlation functions (CCF), the degree of volatility transmissions using generalized autoregressive conditional heteroskedasticity (GARCH) models with the dynamic conditional correlation (DCC) specification and potential determinants with a panel analysis. The main findings reveal that a significant unidirectional Granger causality runs from international wheat price to local retail flour prices for wheat importing countries with an approximate five-month lag, the volatility correlations from international to local markets were strengthened around the period of the 2007–08 food crisis and a higher self-sufficiency rate plays a role in alleviating volatility passthroughs from international markets. This evidence that increasing the SSR of an agricultural commodity is effective in isolating the domestic market is valuable for policymakers in food importing countries. The primary beneficiaries of implementing the policy measure are risk-averse producers and consumers because their utility or welfare improves as the price volatility of foodstuffs declines.
Severity of DSM-5 Cannabis use Disorders in a Nationally Representative Sample of Sexual Minorities
Authors: Boyd Carol J. , Veliz Philip T. , McCabe Sean Esteban 
Published: October 2019

Background: Our study is the first using a national sample to examine the severity of Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) cannabis use disorder (CUD) in sexual minorities. Drawing from current literature, we expected that bisexual individuals would have the highest prevalence of CUD and the most severe form of CUD. Methods: The National Epidemiological Survey on Alcohol and Related Conditions-III (NESARC-III; 2012–2013) provides a nationally representative adult sample ( N = 36,309), including one of the largest samples of sexual minorities. The NESARC-III is large enough to compare subpopulations of sexual minorities on dimensions of substance use disorder severity. Results: Lesbians and gay men were more likely to report mild CUD, whereas bisexuals and respondents “not sure” of their sexual identity were more likely to report severe CUD when compared with heterosexuals. Sexual minorities and heterosexuals who reported lifetime use of medical cannabis had higher odds of having a severe CUD. Sexual minorities had significantly higher odds of lifetime medical cannabis use (adjusted odds ratio [AOR] = 2.39, 95% confidence interval [CI] = 1.42–3.66, P < .001) when compared with heterosexuals, with bisexuals having the highest odds (AOR = 2.81, 95% CI = 1.66–4.75, P < .001). Conclusions: Sexual minorities have the highest odds compared with heterosexuals of developing any CUD. Moreover, the higher rates of severe CUD among bisexuals and those “not sure” have implications for drug prevention with these particularly high-risk groups. It appears that lifetime medical marijuana use may play a role in the development of CUD, although more rigorous measures of medical marijuana use are needed to determine the nature of the relations.

Published: October 2019

Background Recent evidence suggests that the practice of combining opioid use with non-opioid substances is common, though little is known about this phenomenon and how best to address it. Methods We recruited adults in Boston, Massachusetts, with recent opioid use. We conducted semi-structured interviews to explore the practice of combining non-opioid substances with opioids and analyzed transcripts to identify themes. Results Twenty-nine individuals completed interviews. Combining other substances with opioids was a well-known practice: “that's what we call the cocktail.” Participants reported the use of clonidine, gabapentin, benzodiazepines, promethazine, amphetamine salts, quetiapine, barbiturates, cough and cold medications, as well as alcohol and candy in combination with opioids. Participants reported purchasing these substances on the street, stealing them, or getting them from a prescriber. Augmenting the opioid high was a common reason for combining substances. Importantly, participants also reported combining substances to treat psychiatric symptoms. Individuals commonly reported learning about combining substances “from people on the street” but also reported learning from the internet and television. Perceived benefits outweighed safety concerns. Participants also felt that using over-the-counter or prescription medications would be safe. Conclusions Combining a variety of substances with opioids is common and driven by diverse motives. Clinicians caring for opioid-involved patients should consider screening for concurrent use of other substances and discussing the risks of this practice.

Published: October 2019

Background Problematic alcohol use is a common occurrence among college students. While empirically supported interventions exist, their access is typically limited to those with greater resources. There has been an expansion of services provided via telehealth to increase client access to treatment in the health care field. However, the evidence is mixed regarding the effectiveness of face-to-face versus telehealth interventions and there is a gap in the literature regarding brief alcohol interventions delivered via telehealth. As such, the purpose of this study was to test the effectiveness of a well-validated brief alcohol screening and intervention for college students (BASICS) when conducted face-to-face or through a videoconferencing system. Method Participants included 51 college students who engaged in heavy episodic drinking (5+ drinks for males and 4+ drinks for females over a two hour period) over the last two weeks. They were randomly assigned to receive the face-to-face or telehealth intervention and completed a variety of questionnaires throughout. Follow up data on the participant's alcohol use and alcohol-related problems was collected at 1-, 2-, and 3-months. Multilevel modeling in SAS was utilized for analyses, which included the modeling of treatment outcome trajectories and the influence of predictors on the trajectory of change for each outcome. Results Results indicated that the intervention significantly reduced alcohol consumption and related problems regardless of condition. Both conditions saw an increase in treatment satisfaction and therapeutic alliance between the two sessions. Increased therapeutic alliance resulted in greater decreases in alcohol use and related harm across both conditions. Additionally, those with a mental health diagnosis showed greater improvement related to risk reduction for both treatment modalities. Conclusion In sum, the results of this study suggest that telehealth services should be further implemented and the BASICS intervention can be effectively delivered via telehealth for college students.

Abstract
A new data for Fusion power density has been obtained for T-3He and T-T fusion reactions, power density is a substantial term in the researches related to the fusion energy generation and ignition calculations of magnetic confined systems. In the current work, thermal nuclear reactivities, power densities of a fusion reactors and the ignition condition inquiry are achieved by using a new and accurate formula of cross section, the maximum values of fusion power density for T-3He and TT reaction are 1.1×107 W/m3 at T=700 KeV and 4.7×106 W/m3 at T=500 KeV respectively, While Zeff
suggested to be 1.44 for the two reactions. Bremsstrahlung radiation has also been determined to reaching self- sustaining reactors, Bremsstrahlung values are 4.5×106 W/m3 at T=700 MeV and 3.8×106 W/m3 at T=500 MeV for T-3He and TT reaction respectively, ignation values then are 136 KeV for T-T and 155 KeV for T-3He. So small Zeff
mean small ignition and large fusion power. Tritium Fusion Reactions have large ignition temperature than deuterium reactions.

Published: October 2019

Abstract
Roof ventilation gives passive cooling effect in removing hot air from tropical climate buildings. However, little is known about the impacts of building parameters on the passive cooling effect in ancient Myanmar multistage roof buildings. The authors believe that this is the first study to assess the ventilation performance of multistage roof buildings taking into account their typologies, ventilation modes and climatic parameters. This paper presents the ventilation performance of two roof typologies by varying defined parameters from studies in computational fluid dynamic simulations. Simulations were generated by using the 3D steady Reynolds Averaged Navier Stokes equations and k-ε turbulence models. The results of CFD studies revealed that the presence of gable vents allowed better indoor air movement although the indoor air turbulence was depended on the intensity of exterior wind speed and roof typology. It was found that the single gable roof buildings increased the indoor airspeed with insignificant indoor air temperature improvement for thermal comfort. The results of this CFD study substantiate the findings of another dynamic simulation study and support the conclusion that the three-stage roof buildings have more potential to improve a better thermal and ventilation performance if they have gable vents.
Effect of mechanical ventilation on air infiltration rate in a concert hall
Authors: Shi Yuchen , Li Xiaofeng 
Published: October 2019

Abstract
Due to high occupant density, fresh air is essential for audience in a concert hall. Generally, mechanical ventilation system is used to supply outdoor fresh air. Apart from that, uncontrolled air leakage across building exterior (i.e., air infiltration) is also a source of outdoor fresh air. Though ASHRAE requires a positive pressure (i.e., zero infiltration rate) for mechanically ventilated rooms, positive pressure is difficult to be maintained under poor building airtightness or low mechanical ventilation rates. When the positive pressure is not achieved, the existence of air infiltration brings about outdoor air pollutants infiltrating indoors and excessive fresh air cooling/heating load. Therefore, to maintain a good indoor environment and an appropriate fresh air rate, the effect of mechanical ventilation on air infiltration rate must be figured out. This study investigates the variation laws of infiltration rate with mechanical ventilation rate in a concert hall. Infiltration rates under different mechanical ventilation rates were measured based on the particle mass balance method. It is concluded that the relationship between the two rates conforms to the theoretical model proposed by the authors’ previous study.
Comparison of grey-box model and artificial neural network – prediction of surface condensation in residential space
Authors: Ju E J , Lee J H , Park S H , Park C S , Yeo M S 
Published: October 2019

Abstract
To apply real-time predictive control using automated devices for minimizing the risk of surface condensation in a residential space, the authors first developed a nodal network model that simulates the flow of moist air and the thermal behavior of a target area with the given boundary conditions of a space. The lumped model was enhanced using a parameter estimation technique based on the measured temperature, humidity, and schedule data. However, the humidity model prediction performance was still outside the valid range. A data-driven model was then developed using an artificial neural network (ANN) with the measured data that was formerly used to enhance the lumped model. Taking into consideration the possible uncertain characteristics of moist air, it was found that the data-driven model was a more suitable option for predicting the condensation as compared to the physics-based and grey-box models. With a stable range of errors between the simulation outputs and measured data, the ANN model could be useful for model predictive control.
Comfort-oriented control strategies for decentralized ventilation using co-simulation
Authors: Carbonare N , Pflug T , Bongs C , Wagner A 
Published: October 2019

Abstract
Mechanical ventilation systems have acquired relevance in the past years in order to guarantee the hygrothermal comfort and indoor air quality (IAQ) in highly retrofitted residential buildings. The optimization of control strategies could provide a solution to this existing trade-off between energy efficiency, hygrothermal comfort and IAQ. In this publication, we propose a co-simulation approach (using EnergyPlus and Modelica) and a mathematical approximation of the discomfort of the occupant (namely, quadratic for relative humidity and exponential for CO2), and apply them to a demand controlled ventilation (DCV) scheme. Results show that this approach provides around 10% energy savings, while improving the thermal comfort, without compromising the humidity comfort or the IAQ. Finally, the developed functions could allow the control schemes to adapt to different occupant preferences, showing potential for future work.
Evaluation of air change rates for estimating particle dispersion on a reduced scale model
Authors: Cetin Y E , Avci M , Aydin O 
Published: October 2019

Abstract
Similarity between a model and a prototype is important for scale model experimental studies. Proper scaling by considering similarity parameters can lead to valuable results. The objective of this study is to investigate dispersion of fine particles under different air change rates by experimental and numerical techniques. Experimental studies are performed on a 1:5 reduced scale model. Similarity parameters are considered for kinematic and particle dispersion similarities. The RNG k – ε turbulence model is used in the numerical predictions. It is shown that the average room and outlet concentrations get similar values with the removal of accumulation as the air velocity increases. Moreover, it is disclosed that the advantages of the increasing air change rates may have limits in reducing contaminant level.
