The Involvement of a Concerned Significant Other in Gambling Disorder Treatment Outcome

Interpersonal distress is a common feature in gambling disorder and adding a concerned significant other (CSO) to the recovery process could be an effective tool for improving treatment outcome. However, little empirical evidence is available regarding the effectiveness of including a CSO to interventions. We aimed to compare treatment outcomes (i.e. compliance with therapy guidelines, dropout from treatment, and relapse during treatment) in a CBT program involving a CSO to CBT treatment as usual (TAU) without a CSO. The sample comprised male gambling disorder patients (N = 675). The manualized CBT intervention consisted of 16 weekly outpatient group sessions and a 3-month follow-up period. Patient CSOs attended a predetermined number of sessions with the patient and were provided with resources to acquire a better understanding of the disorder, to manage risk situations, and to aid patients in adhering to treatment guidelines. Patients with a CSO had significant higher treatment attendance and reduced dropout compared to patients receiving TAU. Moreover, patients whose spouse was involved in the treatment program were less likely to relapse and adhered to the treatment guidelines more than those with a non-spousal CSO. Our results suggest that incorporating interpersonal support to gambling disorder interventions could potentially improve treatment outcomes.     

Substrate influence on aromatic plant growth in extensive green roofs in a Mediterranean climate

Green roofs have been described as technical solutions to overcome urban environmental problems, such as decrease of vegetation and stormwater management. In the present study, two pilot 20 m² extensive green roofs were implemented in an urban Mediterranean region, at a 1st storey on a warehouse building structure, in order to test the adequacy of different substrates for supporting aromatic plants (Lavandula dentata, Helichrysum italicum, Satureja montana, Thymus caespititius and Thymus pseudolanuginosus). Experimental substrates included expanded clay and granulated cork as main components, supplemented with organic matter and crushed egg shell. A commercial substrate that obeys to FLL guidelines was also tested. Plant growth was assessed and compared within each platform. All experimental substrates proved to be adequate for vegetation growth, with the combination of 70% expanded clay, 15% organic matter and 15% crushed egg shell showing the best results regarding plant establishment and growth over time. Water runoff quality parameters - turbidity, pH, conductivity, NH₄ ⁺, NO₃ ^?, PO₄ ^3? - met standard values required for water reuse for non-potable purposes, such as toilet flushing or irrigation. Preliminary qualitative thermographic measurements comparing surface temperature of different plant species and the substrate showed that temperature of vegetation surface was lower than substrate, reinforcing green roofs benefits of lowering air temperature in their surroundings. The present research shows that aromatic vegetation combined with clay substrates are suitable for green roofs located in countries of the Mediterranean region.     

Loving and living the Zapatista event: understanding affect inside youth Mexican activism

This paper will detail youth political engagement in one of the most important activist organisations that the Mexican city of Puebla (the fourth largest in the country) has known in its recent history. In particular, the paper will focus on the leadership of two of the leaders of this organisation, who were also lovers. As we will see, the relationship between these two activists proved to be very important for this organisation, so much so that when the couple broke up, the entire collective collapsed. In this sense, the theoretical challenge I am interested in is the one of inserting the study of the affective dimension of youth political practices in the social and political contexts in which these practices make sense. It is hoped that by studying this case in a rather explorative way, we will gain a better understanding of how youth politics and engagement interact with interpersonal affect.     

Statistical monitoring of a web server for error rates: a bivariate time-series copula-based modeling approach

The monitoring of web servers through statistical frameworks is of utmost important in order to verify possible suspicious anomalies in network traffic or misuse actions that compromise integrity, confidentiality, and availability of information. In this paper, by considering the Plackett copula function, we propose a bivariate beta-autoregressive moving average time-series model for proportion data over time, which is the case for variables present in web server monitoring such as error rates. To illustrate the proposed methodology, we monitor a Brazilian web server's rate of connection synchronization and rejection errors in a web system, with error logging rate in the past 10?min. In essence, the entire methodology may be generalized to any number of time-series of error rates.     

Generalized normal ARMA model applied to the areas of economy,hydrology, and public policy

The main purpose of this article is the presentation of a new class of time series models which is the merge output of the generalized normal distribution with ideas from the GARMA model. Symmetrically, tails that may be lighter or heavier than the Gaussian distribution, and Gaussian and Laplace distributions as special cases, are the main advantages of the use of generalized normal distribution. The proposed model is called generalized normal autoregressive moving average (GN-ARMA). We exemplify the application of the proposed model adjusting it to the three time series, which are from the areas of economy, hydrology, and public policy.     

The Employment–Hours Trade‐off: Theory and an Application to the Portuguese Case

Abstract. Using traditional production theory, it is possible to estimate production functions in which hours per worker and number of workers hired are treated as endogenous and chosen by the firm, priced respectively by the variable hourly wage and the so‐called quasi‐fixed unit cost. The available data suggested the use of Cobb–Douglas or CES specifications or the use of two‐stage separable technologies, with a second‐level Cobb–Douglas being possible. Quasi‐fixed costs were associated with legal social security payments, which were also conditioned by the data. The estimates for the Portuguese metal products and engineering industries — using cross‐section evidence for 1987 — showed that disaggregation of the labor input is empirically justifiable, and total man‐hours employed and the numbers of workers hired are complements in production. Hours per worker respond negatively to the variable hourly wage and positively to the quasi‐fixed unit cost. Nevertheless, in our framework, this would be so by construction. Total labor costs increase with both the hourly wage and the quasi‐fixed unit costs.     

Robbery victimization of Mexican migrants while crossing the border

We analyse the factors associated with Mexican migrants being victims of robbery or assault while crossing the US–Mexico border, based on an analytical model of the victimization of migration in transit. Drawing on Emif Norte survey, we analyse the prevalence of victimization of robbery or assault to migrants according to migrant's sociodemographic characteristics as well as the journey characteristics, and we use a logistic regression model to assess the way in which such characteristics are associated with being victim of that crime. Findings suggest that migrants who crossed through Tamaulipas and those who hired coyotes in transit or at the border have higher odds of being robbed or assaulted, in contrast, the individual sociodemographic characteristics and crossing with family/friends are not associated with being robbed or assaulted.     

Does Financial Inclusion Diminish Poverty and Inequality? A Panel Data Analysis for Latin American Countries

Despite great developmental efforts in recent decades, Latin America still presents high levels of poverty and inequality when compared to developed nations. As explored widely in the literature, one potential instrument to diminish these issues is financial inclusion, including the access and usage of financial services by all people. Specifically, this paper verifies if financial inclusion and technology adoption decrease the poverty headcount ratio and the Gini index (i.e., inequality) of 13 Latin America countries (Argentina, Bolivia, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Honduras, Panama, Paraguay, Peru, and Uruguay). To perform such analysis, an unbalanced panel dataset was built, and the Feasible Generalized Least Squares (FGLS) and the Limited Information Maximum Likelihood (LIML) techniques were employed. The results suggest that, in accordance with previous studies, financial inclusion is a powerful tool to tackle poverty and inequality. Additionally, the combined effects of financial inclusions and technology (i.e., mobile use) are also capable of decreasing the poverty and inequality levels. We discuss the policy implications of our findings and suggest a future research agenda.

     

The influence of familiarization sessions on the stability of ramp and ballistic isometric torque in older adults

Ramp isometric contractions determine peak torque (PT) and neuromuscular activation (NA), and ballistic contractions can be used to evaluate rate of torque development (RTD) and electrical mechanical delay (EMD). The purposes of this study were to assess the number of sessions required to stabilize ramp and ballistic PT and to compare PT and NA between contractions in older adults. Thirty-five older men and women (age 63.7 ± 3.7 yr, body mass 64.3 ± 10.7 kg, height 159.2 ± 6.6 cm) performed 4 sessions of unilateral ramp and ballistic isometric knee extension, 48 hr apart. PT significantly increased (main time effect p < .05) from the first to the third session, with no further improvements thereafter. There was a trend toward higher PT in ballistic than in ramp contractions. No difference between contraction types on EMG values was observed. Therefore, the authors suggest that 3 familiarization sessions be performed to correctly assess PT. In addition, PT, NA, RTD, and EMD can be assessed with ballistic contraction in older adults.
