Evaluating delinquency policy interventions in Portugal

Social program and policies, interventions, and services, should be required to undergo rigorous systematic evaluation to address the policy question of how society should invest in the treatment of juvenile offenders in the institutional care system. Public policy decisions regarding programs for youths should be grounded on research-based knowledge and experience of academia and practitioners, program participants. Despite developments in intervention science, the existing empirical literature is seriously underdeveloped with respect to the issue of delinquency interventions and policies in Portugal. In other words, there is little systematic knowledge on the effects of existing policies in the youth system. In this paper, we address the available research and evidence on juvenile justice institutional interventions. We seek to explore the extent to which these are 1) informed by previous studies and 2) subject to analysis during and following policy termination.CIEC – Research Centre on Child Studies, IE, UMinho (FCT R&D unit 317), Portugal;National Funds through the FCT (Foundation for Science and Technology) and co-financed by European Regional Development Funds (FEDER) through the Competitiveness and Internationalization Operational Program (POCI) with the reference POCI-01-0145-FEDER-007562info:eu-repo/semantics/publishedVersio

Perceived risk of regular cannabis use in the United States from 2002 to 2012: Differences by sex, age, and race/ethnicity

Introduction: Cannabis is one of the most widely used psychoactive substances in the United States (U.S.). Perceived risk of use is associated with substance use; the recent debate surrounding medicalization and legalization of cannabis in the U.S. has the potential to impact perceived risk of use. Recent estimates are needed to assess temporal changes in, and identify correlates of, perceived risk of cannabis use. Methods: Utilizing data from the 2002–2012 survey years of the National Survey on Drug Use and Health, chi-squared statistics and logistic regression were used to describe temporal changes in perceived risk of regular cannabis use (i.e., once or twice a week), to explore correlates of perceived risk, and to report frequency of cannabis use. Results: Between 2002 and 2012, perceived great risk of regular cannabis use varied significantly overall (p < 0.001). The prevalence of past year non-daily (p < 0.001) and daily use varied significantly during this time (p < 0.001). Controlling for survey year and other confounders, characteristics associated with increased odds of perceived great risk of regular cannabis use included: female sex; Non-White race/ethnicity; age 50+; and family income of $20,000-49,999. Characteristics associated with decreased odds of perceived great risk included: ages 12–17 and 18–25; high school education or greater; total family income of$75,000+; past year non-daily and daily cannabis use; and survey years 2008–2012. Conclusions: Findings characterize trends of perceived risk of regular cannabis use, and past year non-daily and daily cannabis use. Longitudinal studies of the influence of legal status of cannabis at the state-level are needed

Avaliação da composição química e actividade biológica de óleos essenciais de Lavandula spp.

As Lavandula spp. pertencem à família Lamiaceae, conhecidas vulgarmente por rosmaninho, são das plantas medicinais mais populares e de grande importância económica. Têm sido utilizadas durante séculos, secas, frescas ou os seus óleos essenciais, num grande número de aplicações, na indústria farmacêutica, na aromaterapia e cosmética como fragrância. Algumas espécies do género Lavandula, apesar de apresentarem propriedades etnobotânicas semelhantes, diferem na composição dos óleos essenciais, podendo estes constituir importantes marcadores de quimiotipo para caracterização destas espécies. Para este estudo foram seleccionadas espécies expontâneas do Alentejo, como a L. stoechas L. subsps. luisieri (Rozeira) Rozeira, L. pedunculata (Mill.) Cav. subsp. pedunculata var. lusitanica Chaytor, e do Algarve, L. viridis L’Hér. Estes espécimes são frequentes nos sub-bosques de azinhais, sobreirais e pinhais de pinheiro bravo, matagais, estevais e sargaçais, em solos arenosos, quartzíticos, graníticos ou xistosos. O objectivo deste estudo foi caracterizar os óleos essenciais das espécies-alvo no que concerne à composição química com vista a avaliar a sua diversidade e avaliar as actividades antimicrobiana e antioxidante dos óleos essenciais da espiga e folha de L. luisieri e de L. viridis

Patterns of drug use and HIV infection among adults in a nationally representative sample

Background: Little is known about drug use patterns among people living with HIV in comparison to an uninfected group in the general population. The aim of this study was to investigate the association between legal and illegal drug use and HIV infection in a nationally representative sample of adults in the United States. Methods: Public use data files (2005–2014) from the National Survey on Drug Use and Health (NSDUH) were used. Respondents were asked whether a medical professional had ever told them that they had HIV/AIDS. Ever (lifetime), past-year, and past month use of cigarettes, alcohol, marijuana, cocaine, heroin, hallucinogens, inhalants, and nonmedical use of psychotherapeutics was assessed. Logistic regression was used to estimate adjusted odds ratios (aOR) of the relationship between drug use and HIV infection, adjusting for demographics. Results: Of 377,787 respondents age 18 and older, 548 (0.19%) were categorized as HIV-infected. Ever use of cigarettes, tobacco, marijuana, cocaine, heroin, hallucinogens, inhalants, and psychotherapeutics was higher in HIV-infected individuals compared to HIV-uninfected individuals after adjustment for sex, age, race/ethnicity, education, total family income, and marital status. Past year and past month use was also higher for HIV-infected individuals for all substances aside from alcohol. Conclusions: In a nationally representative sample, there are higher levels of drug use and DSM-IV dependence among the HIV-infected population compared to the HIV-uninfected population. This is of concern because drug use and dependence can impede engagement in HIV care and adherence to antiretroviral therapy

Production, composition, and application of coffee and its industrial residues

Coffee is one of the most consumed beverages in the world and is the second largest traded commodity after petroleum. Due to the great demand of this product, large amounts of residues are generated in the coffee industry, which are toxic and represent serious environmental problems. Coffee silverskin and spent coffee grounds are the main coffee industry residues, obtained during the beans roasting, and the process to prepare “instant coffee”, respectively. Recently, some attempts have been made to use these residues for energy or value-added compounds production, as strategies to reduce their toxicity levels, while adding value to them. The present article provides an overview regarding coffee and its main industrial residues. In a first part, the composition of beans and their processing, as well as data about the coffee world production and exportation, are presented. In the sequence, the characteristics, chemical composition, and application of the main coffee industry residues are reviewed. Based on these data, it was concluded that coffee may be considered as one of the most valuable primary products in world trade, crucial to the economies and politics of many developing countries since its cultivation, processing, trading, transportation, and marketing provide employment for millions of people. As a consequence of this big market, the reuse of the main coffee industry residues is of large importance from environmental and economical viewpoints

Substance-use coping and self-rated health among US middle-aged and older adults

The prevalence of alcohol, drug, and tobacco use among US middle-aged and older adults is increasing. A subset of this population uses substances to cope with stress, but the characteristics of these individuals, and the association between substance-use coping and health outcomes remain unclear. We identified correlates of substance-use coping and measured its association with self-rated health in a community-based sample of adults aged 54–99 in the Health and Retirement Study (HRS). In the 2008 HRS, 1351 participants reported their frequency of prescription/other drug-, alcohol-, and cigarette-use coping with stress and reported self-rated health (excellent/very good, good, or fair/poor); 1201 of these participants also reported self-rated health in 2010. One in six participants frequently used substances to cope. The oldest participants were least likely to engage in frequent alcohol-use coping. Those with elevated depressive symptoms were more likely to frequently engage in cigarette- and prescription/other drug-use coping. In multivariable-adjusted analyses, participants who frequently used cigarettes (compared to participants who infrequently used cigarettes) to cope had 2.7 times (95% CI = 1.1–6.7) the odds of poor (vs. excellent) self-rated health. Relative to participants who infrequently used prescription/other drugs to cope, participants who frequently used prescription/other drugs to cope had 2.4 times (95% CI = 1.1–5.1) the odds of reporting poor self-rated health. The association between prescription/other drug-use coping in 2008 and self-rated health in 2010 was statistically significant (relative OR = 3.5, 95% CI = 1.7–7.2). Participants engaging in substance-use coping likely have particular demographic and clinical characteristics. Interventions to reduce substance-use coping may prevent adverse health outcomes

How healthy are survey respondents compared with the general population? Using survey-linked death records to compare mortality outcomes

Background: National surveys are used to capture US health trends and set clinical guidelines, yet the sampling frame often includes those in non-institutional households, potentially missing those most vulnerable for poor health. Declining response rates in national surveys also represent a challenge, and existing inputs to survey weights have limitations. We compared mortality rates between those who respond to surveys and the general population over time. Methods: Survey respondents from twenty waves of the National Health Interview Survey from 1990 through 2009 who have been linked to death records through 31 December 2011 were included. For each cohort in the survey, we estimated their mortality rates along with that cohort's mortality rate in the census population using vital statistics records and differences were examined using Poisson models. Results: In all years, survey respondents had lower mortality rates compared with the general population, when data were both weighted and unweighted. Among men, survey respondents in the weighted sample had 0.86 (95% C.I. 0.853-0.868) times the mortality rate of the general population (among women, RR=0.887; 95% C.I. 0.879-0.895). Differences in mortality are evident along all points of the life course. Differences have remained relatively stable over time. Conclusion: Survey respondents have lower death rates than the general US population, suggesting that they are a systematically healthier source population. Incorporating non-household samples and revised weighting strategies to account for sample frame exclusion and non-response may allow for more rigorous estimation of the US population's health

An Assessment of Pharmacological Properties of Schinus Essential Oils: A Soft Computing Approach

Plants of genus Schinus are native South America and introduced in Mediterranean countries, a long time ago. Some Schinus species have been used in folk medicine, and Essential Oils of Schinus spp. (EOs) have been reported as having antimicrobial, anti-tumoural and anti-inflammatory properties. Such assets are related with the EOs chemical composition that depends largely on the species, the geographic and climatic region, and on the part of the plants used. Considering the difficulty to infer the pharmacological properties of EOs of Schinus species without a hard experimental setting, this work will focus on the development of an Artificial Intelligence grounded Decision Support System to predict pharmacological properties of Schinus EOs. The computational framework was built on top of a Logic Programming Case Base approach to knowledge representation and reasoning, which caters to the handling of incomplete, unknown, or even self-contradictory information. New clustering methods centered on an analysis of attribute’s similarities were used to distinguish and aggregate historical data according to the context under which it was added to the Case Base, therefore enhancing the prediction process

Delincuencia juvenil, moralidad y exclusión social: resultados preliminares del ISRD-3 en Oporto

En las últimas décadas el fenómeno de la delincuencia juvenil ha sido un tema de gran interés en la literatura criminológica. En este sentido se han desarrollado instrumentos propios para medir las “cifras negras” de delincuencia juvenil, además del comportamiento antisocial. El proyecto colaborativo International Self- Reported Delinquency surgió en la década de los 90 con el propósito de dar respuesta a esta necesidad, a través de un instrumento de auto-relato implementando en contexto escolar, además de posibilitar el estudio de diferentes teorías criminológicas explicativas, permitiendo comparaciones trasnacionales. Uno de las teorías introducidas en ésta última versión es la teoría de la acción situacional (Winström, 2006), según la cual todas las acciones son el resultado de una persona en contacto con el medio ambiente específico y los actos de violencia son comportamientos guiados por valores morales. Tomando en consideración esta teoría, es esperable que las reglas morales interfieran más sobre la delincuencia y comportamiento violento en jóvenes provenientes de ambientes marginales. Partiendo de esta hipótesis de estudio, serán presentados, los resultados preliminares del estudio ISRD-3 llevado a cabo en la ciudad de Oporto entre los meses de Octubre de 2015 y Mayo de 2016. A través de un análisis estadístico de los datos, se mostrará la influencia de la transmisión de valores morales y el autocontrol, en dos contextos diferentes; comparando los datos de jóvenes provenientes de centros educativos TEIP, o centros considerados de “intervención especial”, con el resto de jóvenes encuestados. Las conclusiones de estudio pueden servir para gestionar los riesgos de forma correcta y mejorar el impacto de las políticas de prevención en el campo de la educación.CIEC – Research Centre on Child Studies, IE, UMinho (FCT R&D unit 317), PortugalNational Funds through the FCT (Foundation for Science and Technology) and co-financed by European Regional Development Funds (FEDER) through the Competitiveness and Internationalization Operational Program (POCI) with the reference POCI-01-0145-FEDER-007562info:eu-repo/semantics/publishedVersio

Trends in Marijuana Use Among Pregnant and Nonpregnant Reproductive-Aged Women, 2002-2014

Between 2001 and 2013, marijuana use among US adults more than doubled, many states legalized marijuana use, and attitudes toward marijuana became more permissive. In aggregated 2007-2012 data, 3.9% of pregnant women and 7.6% of nonpregnant reproductive-aged women reported past-month marijuana use. Although the evidence is mixed, human and animal studies suggest that prenatal marijuana exposure may be associated with poor offspring outcomes (eg, low birth weight, impaired neurodevelopment). The American College of Obstetricians and Gynecologists recommends that pregnant women and women contemplating pregnancy be screened for and discouraged from using marijuana and other substances. Whether marijuana use has changed over time among pregnant and nonpregnant reproductive-aged women is unknown
