In this paper, we study the effect of induced positive and negative moods on traders' willingness to trade (pay and accept) in experimental asset markets.

We conduct experimental asset markets where subjects undergo a mood induction procedure prior to trade. After the subjects are induced with either negative or positive affect, they can trade an experimental asset with a known stream of dividends for a known number of periods.

We first show that both positive and negative affects are associated with larger positive deviations from fundamental values. We also show that when subjects are induced with positive mood, they bid higher prices but for fewer units of the stock. On the supply side, positive affect is associated with higher prices and quantities, and consequently in higher willingness to offer. Finally, we use our experimental data to test existing theories on mood effect. We find that negative affect is related to momentum trading, while positive affect is associated with information processing.

To our knowledge, this is the first work that studies the effect of mood on traders' behavior, rather than market outcomes.

Substance use treatment (SUT) among migrants and ethnic minorities is an underresearched domain in European countries, although preliminary studies point out disparities in treatment use and access compared to general populations. This paper aims to identify the main characteristics of and the types of services solicited by non-nationals in Belgium.

This paper compares the types of SUT services used by Belgian and non-national clients. Second, the referral source for Belgian and non-national clients is considered. Third, the study compares the client characteristics of Belgian and non-national clients. This descriptive analysis is based on aggregated data sets in the European treatment demand indicator (TDI) registry including all Belgian treatment episodes between 2012 and 2014.

Non-national clients were more often located in outpatient SUT and were less often referred by general practitioners and hospitals, compared to Belgian clients. Third-country clients appear to have lower socioeconomic statuses (education, employment, housing) than Belgian clients. Non-national youngsters and third-country females appear to be underrepresented in Belgian SUT compared to their presence in the general population. The gender gap is larger among third-country clients than among Belgian clients.

These associations between nationality and solicited services, gender, education, employment, housing and referral document treatment gaps among some non-nationals that require special attention in targeted treatment. In the European context, further research is needed on better monitoring migration background in the European TDI registries.

The overrepresentation of non-nationals in low-threshold opioid substitution treatment services and their underrepresentation in high-threshold residential services requires an in-depth analysis of the core goals of these respective services. Residential services, for instance, should consider how a dominant focus on speech therapy hampers access to treatment for these populations and how access for these populations could be enhanced by modifying or diversifying methods in treatment.

To the best of the authors’ knowledge, this is the first paper that analyses the national indicator in a European TDI data set.

The opioid epidemic in the USA, the new psychoactive substances emerging on the market and the recent increase in cocaine treatment demands in Western Europe, all emphasise the importance of monitoring the use and harms of drugs over time. To be informed about new consumption patterns, this study aims to study the trends among people entering treatment for substance use in Belgium.

Belgian data from the Treatment Demand Indicator collected between 2015 and 2019 were used. A reference group of treatment units was selected to allow for comparisons between the different years. Trend analysis was performed by using a joinpoint regression among different regions and groups of clients.

The drugs of choice that were most frequently mentioned among the 23,000 analysed treatment episodes were alcohol and cannabis. Both remained relatively stable over time. Heroin seemed to be decreasing significantly at the national level, but increased in Brussels. Benzodiazepines decreased significantly in Flanders and Brussels, but not in Wallonia. On the other hand, reports of crack cocaine increased significantly in the three regions with a more pronounced trend in Wallonia and Brussels. Substances such as fentanyl, methamphetamine, ketamine or volatile inhalants have been mentioned significantly more by people entering treatment in 2019, although their contribution to the total number is still limited.

To the best of the authors’ knowledge, this study is the first to evaluate trends for all drugs of choice at a national and regional level. These results might not only benefit national policymakers but also other countries with similar alcohol or drug use patterns.

The purpose of this paper is to estimate the share of multiple substance disorders among clients entering treatment for substance-related problems, to identify the most frequent combinations of the substances involved and to investigate the profiles of the clients involved.

Data were taken from the Swiss treatment monitoring system act-info applied among inpatient and outpatient facilities (reporting years 2013–2015). All cases with information on multiple substance disorders, according to a definition close to the diagnosis F19 from the ICD-10 classification of disease were included. The measurements comprised designated primary substance, existing multiple substance use disorder, substances involved and basic socio-demographics.

From 10,009 clients included in the study, 1,653 (16.5 per cent) were reported as having multiple substance use disorders. A great variety of substance combinations was identified and alcohol was found in the majority of them.

Treatment strategies targeting accurately substance-related disorders as a whole complex should be promoted. In particular the alcohol-related aspect of the disorder should not be neglected when the focus is on illegal drugs.

Multiple substance use was until recently not sufficiently documented in treatment monitoring systems. A recent version of the European treatment demand indicator (TDI) has introduced the notion of “polydrug use problem” as complementary information to the primary substance, which remains the key variable for reporting treatment demand. This study represents a first attempt to explore systematically this new data.

Many studies show that incarcerated populations have higher rates of problem drug use than the general population. The purpose of this paper is to analyse trends in addiction treatment demand in prisons in Ireland from 2009 to 2014 using available national surveillance data in order to identify any implications for practice and policy.

National surveillance data on treatment episodes for problem drug and alcohol use from 2009 to 2014, collected annually by the National Drug Treatment Reporting System (NDTRS), were analysed.

In total, 6 per cent of all treatment episodes recorded by the NDTRS between 2009 and 2014 were from prison services. The number of prison service treatment episodes increased from 964 in 2009 to 1,063 in 2014. Opiates were the main reason for treatment, followed by alcohol, cocaine and cannabis. The majority (94–98 per cent) of treatment episodes involved males (median age of 29 years) and low educational attainment, with 79.5–85.1 per cent leaving school before completion of second level. The percentage of treatment episodes with a history of ever injecting drugs increased from 20.9 per cent in 2009 to 31.0 per cent in 2014.

This study can help policy development and service planning in addiction treatment in prison as it provides an insight into the potential needs of incarcerated populations. It also provides a baseline from which to measure any changes in provision of treatment in prison over time.

This is the first study to analyse treatment episodes in prison using routine surveillance data in Ireland. Analysis of these data can provide useful information, not currently available elsewhere.

The aim of this paper is to reveal these problems and to derive recommendations for improvement. In the field of alcohol use disorders (AUDs), two common complaints are the large treatment gap that exists because only a small percentage of people with an AUD are in treatment; and the prolonged lag that typically exists between the emergence of problematic symptoms and actual on set of treatment. However, there also are no clear definitions for these terms – “treatment gap” and “treatment lag” – and, therefore, no consensus regarding how to quantify them. For this reason, it is difficult to compare the results of studies assessing either of these measures.

A non-systematic literature search and logical-analytical investigation was performed of immanent problems related to definitions and measurements aiming to enhance understanding in this area and derive suggestions for improvement.

The following four fundamental questions were identified: How does one operationalise the need to change substance use behaviours? Which interventions can justifiably be called treatment? Is treatment always necessary? and How regularly do patients need to be in contact with a treatment system to be considered “in treatment”? Potential approaches to answering these questions are discussed and recommendations made for future studies to determine how the treatment gap and treatment lag should be derived.

The derived recommendations should make the calculation of treatment gap and treatment lag more transparent and comparable between studies. They also may serve as checklists for future studies on the treatment gap and lag in the AUD field.

The coronavirus-19 (COVID-19) pandemic mobilized the international scientific community in the search for its cure and containment. The purpose of this paper is to examine the nature of the rapid response to the COVID-19 of the scientific community in selected Latin American countries (Argentina, Brazil, Chile, Colombia and Mexico) in the period running from January to August 2020. Rapid response is reconceptualized from its original meaning in health policy, as the swift mobilization of existing scientific resources to address an emergency (DeVita et al., 2017).

The paper explores the rapid response of the Argentinian, Brazilian, Chilean, Colombian and Mexican scientific communities from the perspective of bibliometric and altmetric data. The authors will examine scientific publications indexed to the Web of Science (WoS) dealing with COVID-19. Besides patterns of scientific output and impact as measured by citations, the authors complement the analysis with altmetric analysis. The aim is to verify whether or not factors that explain the extent of scientific impact can also be identified with respect to the wider impact made evident by altmetric indicators (Haustein, 2016).

The authors identified a somewhat limited response of the Argentinian, Brazilian, Chilean, Colombian and Mexican scientific communities to COVID-19 in terms of quantity of publications. The authorship of publications in the topic of COVID-19 was associated with authorship of publications dealing with locally relevant diseases. Some factors appear to contribute to visibility of scientific outputs. Papers that involved wider international collaborations and authors with previous publications in arboviruses were associated with higher levels of citations. Previous work on arbovirus was also associated with higher altmetric attention. The country of origin of authors exerted a positive effect on altmetric indicators.

A limitation in the analysis is that, due to the nature of the data source (WoS), the authors were unable to verify the career status and the productivity of the authors in the sample. Nonetheless, the results appear to suggest that there is some overlapping in authors conducting research in Arboviruses and COVID-19. Career status and productivity should be the focus of future research.

In the context of countries with limited scientific resources, like the ones investigated in our Latin American sample, previous efforts in the study of locally relevant diseases may contribute to the creation of an expertise that can be applied when a health emergency brings about a novel disease.

The originality of the paper rests on the fact that the authors identified that previous work on arbovirus contributed to the scientific visibility of publications on COVID-19.

This paper aims to explore how the Celtic Tiger economic boom and Great Recession influenced drug and alcohol use in one Irish city.

Semi-structured interviews were conducted with 48 people, living in Cork City, who had previously used drugs and/or alcohol problematically. All participants had engaged with services for their problematic use and had at least one year of abstinence at time of interview.

Some participants reported that their drug and/or alcohol consumption increased during the economic boom; others, who were already in (self-defined) active addiction, reported how full employment lessened some of the harms of their problematic use. For others, problematic use struck once the economy entered a downturn and, heavy drink and drug use became a means of soothing the strains of economic recession.

The paper provides two key contributions. Methodologically, it demonstrates how large-scale national quantitative data can mask local idiosyncratic tendencies, suggesting the need for mixed-method approaches for understanding drug market trends. The paper also provides insights into the impact of global and local economic conditions on drug and alcohol consumption in Ireland.

The purpose of this paper is to explore the relationship between stress due to mistreatment by patients and caregivers’ own well-being indicators (anxiety, depression, and behavioral stress indicators). Based on predictions consistent with the job demands-resources model, it is anticipated that satisfaction with job resources would moderate the relationship between mistreatment by patients and well-being indicators.

Hypotheses were tested with a sample of 182 employees in a leading training and research university hospital in Istanbul, Turkey. Results were partially replicated for a separate sample of 122 healthcare workers. Data were collected using the survey methodology.

The findings suggest that patient injustice is positively related to depression and behavioral stress indicators when satisfaction with job resources is high. Results illustrate that satisfaction with job resources has a sensitizing, rather than a buffering, role on the relation between mistreatment by patients, depression, and behavioral stress indicators, negatively affecting employees with higher levels of satisfaction with job resources.

Organizational justice researchers recently started recognizing that in addition to organizational insiders, organizational outsiders such as customers and patients may also be sources of fair and unfair treatment. Based on this stream of research, unfair treatment from outsiders is associated with retaliation and a variety of negative employee outcomes. The study extends the currently accumulated work by examining how mistreatment from care recipients relates to healthcare workers’ own health outcomes.

The textile industry is one of the largest and most important industrial sectors in India. Because the textile industry consumes large quantities of water and produces highly polluted water discharge, its environmental impact is high. Water is expensive to use, treat and dispose of. Therefore, water conservation and reuse are critical necessity for the textile industry because decreasing water and wastewater treatment and recycling costs can be beneficial.

This research neutralized the pH during dyeing industry wastewater treatment. The system should be robust to erroneous sensor measurements. A pH meter was developed and used to monitor the pH of wastewater hourly before and after HCl treatment.

HCl was used to neutralize the pH of wastewater from 9 to 7.5. The amount of HCl was optimized depending on the wastewater. Three wastewater treatment methods were used, namely, HCl, wash water and reverse osmosis (RO) treatments. The HCl treatment was the most effective for decreasing the pH; the wash water treatment was the most effective for decreasing the total dissolved solids (TDS), total suspended solids (TSS) total hardness and chemical oxygen demand; and the RO treatment was the most effective for decreasing the biochemical oxygen demand, TDS, TSS, total hardness and Cl⁻ concentration.

The pH should be monitored during the textile dyeing because the addition of color to textile fabrics is the most effective at neutral pH. This study evaluated several parameters of wastewater, including pH, color, TSS and TDS. The fabricated digital pH meter provided superior results than conventional measuring devices. The goal was to maintain a neutral pH during dyeing and recycle wastewater to improve environmental sustainability. The newly developed digital pH meter was less expensive and more precise than traditional pH meters. Before reusing and recycling, wastewater underwent ultrafiltration and RO treatment.
