The Codevelopment of Group Relationships: The Role of Individual Group Member's and Other Group Members' Mutual Influence and Shared Group Environment
2019
Although recent research has provided empirical support for the codevelopment of group interaction (defined as development in a common direction of perceptions of group relationships), no studies have yet investigated the "causes" of codevelopment among group members in the long term. The aim of the current study is to examine how the perceptions of an individual group member, and other group members, regarding group relationships influence each other over the course of treatment. We analyzed group data from 168 adult obese patients who participated in (1 of 20) 12-session therapy groups for weight management. Group relationships were measured by the Group Questionnaire (Krogel et al., 2013…
The synthetic cannabinoid 5F-MDMB-PICA: A case series
2020
5F-MDMB-PICA has been detected in products sold on the internet as well as in biological samples since 2016. It is associated with serious adverse health and behavioral effects and even death. Herein we report on twelve cases with proven 5F-MDMB-PICA consumption, including three fatalities, four cases of driving under the influence of drugs and five other criminal acts. In these cases, 5F-MDMB-PICA was detected in postmortem blood or serum. Concentrations ranged from 0.1-16ng/mL. In some blood (serum) and urine samples, the hydrolysis metabolite of 5F-MDMB-PICA (M12) could also be detected. In this case series, co-consumption with other drugs occurred in 9 of 12 cases, most commonly alcohol…
Mono-/polyintoxication with 5F-ADB: A case series.
2019
Abstract 5F-ADB is an indazole-based synthetic cannabinoid. In recent years, it has been detected in legal high products as well as in biological samples and is associated with serious adverse health, behavioral effects and even death. Due to the fast pace of the market of synthetic cannabinoids, data on such newly appearing substances are scarce. As pharmacological properties are often investigated in vitro or by using animal experiments, reports on synthetic cannabinoid findings in human samples along with corresponding case history descriptions are valuable for the interpretation of upcoming routine cases. Herein we report five cases with verified 5F-ADB consumption, including three fata…
Forecasting Changes in Religiosity and Existential Security with an Agent-Based Model
2018
We employ existing data sets and agent-based modeling to forecast changes in religiosity and existential security among a collective of individuals over time. Existential security reflects the extent of economic, socioeconomic and human development provided by society. Our model includes agents in social networks interacting with one another based on the education level of the agents, the religious practices of the agents, and each agent's existential security within their natural and social environments. The data used to inform the values and relationships among these variables is based on rigorous statistical analysis of the International Social Survey Programme Religion Module (ISSP) and…
ABM of Civil Violence: ODD Description
2017
This chapter contains a description of the proposed agent-based model, using the well-known “Overview, Design Concepts and Details” protocol. The model was implemented in NetLogo and is based on the same two types of agents—citizens and law-enforcement—as in Epstein’s model, but “citizen” agents have one subtype (“activist”) used for implementing network influence effects. The salient aspects of the model description are centered on the submodels for the risk perception, the expression of hardship in terms of value-sensitive relative deprivation, endogenous legitimacy feedback and network influence effects, which provide extensions to Epstein’s model. The model includes two networks called …
Influence économique et concurrence au sein d'une agglomération
1986
La définition d'un indicateur de centralité do chaque zone d'une agglomération peut reposer sur l'utilisation de mesures d'accessibilité (type potentiel) et d'influence des zones considérées. (FUSTIER, GARLANDIERX ROUGET. - 1985). L'indicateur d'influence brute est présentement corrigé pour tenir compte de la concurrence interzones dans l'espace urbain. La définition et les propriétés générales dë l'indicateur d'influence effective sont présentées dans une première partie et illustrées sur un exemple numérique. Une seconde partie est consacrée à la présentation des résultats d'une application au cas de l'agglomération dijonnaise. Plusieurs simulations relatives à diverses répartitions des f…
Aggressive and nonaggressive rejected students: An analysis of their differences
2006
The present study aimed to analyze differences between aggressive and nonaggressive rejected students in four sets of variables: personal, family, school, and social. Participants in the study were 843 Spanish adolescents ranging in age from 11 to 16 years old, of whom 47% were boys. Results indicated that these two subgroups of rejected students show a different profile. Aggressive rejected students informed of lower levels of family self-esteem, less parental support, higher levels of aggression between their parents at home, and a more offensive parent–child communication in comparison with nonaggressive rejected adolescents. Moreover, aggressive rejected students showed lower levels of …
Processing of amorphous Si by pulsed laser irradiation at different wavelengths
2012
Amorphous Si thin films deposited on thermally oxidized Si wafers have been processed by the 2 nd and 3 rd harmonics of Nd:YAG laser. Surface modification of amorphous silicon layers have been investigated by scanning electron microscopy before and after chemical etching of processed silicon films. The super-lateral crystal growth regime was achieved with laser fluence of 280 mJ/cm 2 for the 2 nd harmonics and 155 mJ/cm 2 for the 3 rd harmonics. The grain size in polycrystalline Si samples prepared by successive crystallization in the lateral growth regime is about 0.5 - 1 μm.
Influence of fluorine on the synthesis of anatase TiO2for photocatalytic partial oxidation: Are exposed facets the main actors?
2018
Anatase TiO2 samples were synthesized in the presence of different amounts of HF acid with the aim of understanding the effect of the presence of fluorine on the photocatalytic activity. It is well known that the presence of fluoride ions influences the photocatalytic performance by adsorption on the surface of TiO2 and that they are capping agents in the control of specific exposed facets. The samples were characterized by X-ray diffraction (XRD), Raman spectroscopy, nitrogen adsorption–desorption measurements, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis spectrophotometry, and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity was eva…
Pulsed laser growth and characterization of thin films on titanium substrates
2007
Abstract Colored layers were obtained by laser surface treatment of Ti substrates with a pulsed Nd:YAG Q-switched laser. The changes in the morphology, structure and chemical composition of the layers were studied by SEM, EDS, XPS, SIMS and Raman spectroscopy as a function of the laser fluence in the 4–60 J cm −2 . For laser fluences lower than 25 J cm −2 , the layers are colorless or yellow. Their surface is smooth, but they display cracks which increase when the fluence increases. The O/Ti ratio, determined by XPS analysis, varies from 0.7 (colorless layers) to 1.3 (yellow layer). Moreover, XPS spectra evidence non-negligible amounts of nitrogen and carbon in these layers. Raman spectra s…
