Measurement Error-Corrected Estimation of Clinically Significant Change Trajectories for Interventions Targeting Comorbid PTSD and Substance Use Disorders in OEF/OIF Veterans

In randomized control trials (RCTs), a focus on average differences between treatment arms often limits our understanding of whether individuals show clinically significant improvement or deterioration. The present study examined differences in individual-level clinical significance trajectories between Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE) and Relapse Prevention (RP). Eighty-one treatment-seeking veterans with a comorbid PTSD/SUD diagnosis were randomized to COPE or RP; data from an additional n = 48 patients who did not meet criteria for both disorders was used to establish a normative threshold. A newly developed, modernized approach to the Jacobson and Truax (1991) clinically significant change framework, using (a) moderated nonlinear factor analysis (MNLFA) scale scoring and (b) measurement error-corrected multilevel modeling (MEC-MLM) was used; this approach was compared to other approaches using conventional total scores and/or assuming no measurement error. Using a conventional approach to estimating the Reliable Change Index (RCI) yielded no differences between COPE and RP in the percentage of patients achieving statistically significant improvement (SSI; 88.9% for both groups). However, under MNLFA/MEC-MLM, higher percentages of patients receiving COPE (75.0%) achieved SSI compared to RP (40.7%). Findings suggest that, even though COPE and RP appear to reduce the same number of PTSD symptoms, MNLFA scoring of outcome measures gives greater weight to interventions that target and reduce “hallmark” PTSD symptoms.     

A scoping review of predictors of driving under the influence of cannabis (DUIC) in young drivers

BackgroundRecreational and medical legalization of cannabis or marijuana use in countries and states continues to increase. Young adults aged 16–24 years have the highest prevalence rates of cannabis use. Young driver cannabis use is an incompletely understood traffic safety issue.ObjectivesThe purposes of this scoping review were to characterize the predictors of driving under the influence of cannabis (DUIC) among healthy young drivers and to identify research gaps.Inclusion criteriaA self-reported measure of DUIC and a correlation (r, odds ratio, risk ratio) to demographic or behavioral variables such as age, gender and frequency of use was required for inclusionSources of evidenceAPA PsycInfo, SPORTDiscus, Academic Search Complete, Google Scholar, MEDLINE Complete, Scopus, Embase, ERIC, TRID and POPLINE databases were searched using an a priori protocol.MethodsThe PRISMA-ScR methods and checklist were used to conduct the scoping review. After the removal of duplicates, abstract screening (N = 999), and full-text review (N = 173), 19 primary studies met inclusion criteria. Predictors were coded and mapped into four primary thematic categories: social, individual, driving and substance use.ResultsOf the included studies, a total of 52,197 respondents were surveyed in-person or online and 51.8 percent were males. The predominant predictors of DUIC included being a male, high school senior, with lower grades, having a younger ‘age of first cannabis use’, a higher frequency of consumption, a reduced perception of danger, repeatedly binge drinking, a history of driving under the influence of alcohol and living with fewer parents.Research gapsIdentified research gaps include methods used to study young drivers, cannabis edibles, chronic user tolerance, driver adaptation, passengers of drivers who consumed cannabis, combined use with other legal and illicit drugs, and combined smartphone and cannabis use.ConclusionThe results of this scoping review can be used to develop and target general and specific predictors of DUIC in novice, teen and young drivers. Additional research designs will be required to gain a more complete evidence-based understanding of the effects of cannabis on young drivers.

Analyse du cadre réglementaire des certificats médicaux demandés par une municipalité en 2019

Medical certificates have a regular place in general medicine consultation. Since 2011, the french law has highlighted the absence of regulatory support of certain certificates, in particular of public services. The objective of this study was to find out which regulatory texts were based on the medical certificates required by a municipal administration, 8 years after the 2011 rationalization circular?Material and methodQualitative study by observation and critical analysis of certificates by literature reviews according to the main PRISMA quality criteria (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes). The first step consisted of the exhaustive collection of the medical certificates provided by the municipality, for the citizens or the employees of the city. The origin of one of the municipal services was the only criterion for inclusion. The second stage consisted in analyzing the certificates according to the law by using databases classified depending on their level, taking their regulatory value into account as a priority. The research equations were constructed with an inductive process as the certificates were collected.ResultsForty-two certificates were collected and analyzed. Twenty-seven had regulatory support, two of which (not concerned in general medicine) complied with its content. No regulatory support was found for the 15 other certificates. The regulatory vagueness around sports accidents, or even the abuse of authority, are explanations for these certificates without existing or respected regulatory support.ConclusionThe general practitioner is put in a difficult and ambivalent position. A major institutional commitment should be considered for the rationalization of medical certificates, in particular through medical education, health education for users and law enforcement.     

Computational modeling of organisational learning by self-modeling networks

Within organisational learning literature, mental models are considered a vehicle for both individual learning and organizational learning. By learning individual mental models (and making them explicit), a basis for formation of shared mental models for the level of the organization is created, which after its formation can then be adopted by individuals. This provides mechanisms for organizational learning. These mechanisms have been used as a basis for an adaptive computational network model. The model is illustrated by a not too complex but realistic case study.

An Analysis of Fundamental Issues in the Research of Artificial Intelligence Ethical Risk Prevention

While receiving widespread attention, the fundamental issues in the research of artificial intelligence (AI) ethical risk prevention need to be probed and articulated. Although the relevant research is still at an initial stage with long-term tasks, it has a very important social significance. The strategic goals of AI ethical risk prevention research are clarifying ethical risks, taking flexible and effective measures, and providing ethical support for the development of AI technology. This paper argues that key tasks must be of the top priority, such as broadening the theoretical foundation, evaluating ethical risks, realizing ethical design and solving core ethical risks. Therefore, the research of AI ethical risk prevention can be substantially promoted.     

儿童语言和认知（思维）发展的关系

在对幼儿从出生到３岁语言发展追踪研究和有关实验研究结果的基础上,比较、分析儿童语言和认知（思维）发展的各阶段及起作用的因素,探讨语言发展和认知发展的关系,提出以下几点看法：（１）儿童在１岁前（前语言期）的具体思维阶段有认知（有感知、记忆、表象和思维）,但还没有真正的语言。这说明语言不是先于思维,也不是所有的思维都与语言相联系。但是,人类特有的抽象思维却与语言有着密切的联系。（２）认知（思维）发展是语言发展的基础。（３）认知（思维）发展和语言发展的关系是双向的,辩证的,是复杂地交互作用的。（４）应以辩证的唯物主义的观点来看语言和认知（思维）的产生。人类所以有语言,有高度抽象概括的思维,都源于人类的实践活动。     

Understanding autism: how family therapists can support parents of children with autism spectrum disorders

The number of children diagnosed with an Autism Spectrum Disorder has increased dramatically in the last 20 years. Parents of children with autism experience a variety of chronic and acute stressors that can erode marital satisfaction and family functioning. Family therapists are well-suited to help parents stay connected to each other as they create a "new normal." However, family therapists need updated information about autism, and they need to understand how family therapy can help parents of children with autism. Because having a child with autism affects multiple domains of family life, this paper explores how family therapists can utilize an integrative approach with parents, enabling them to flexibly work with the domains of action, meaning, and emotion.     

Mapping Chinese Folk Religion in Mainland China and Taiwan

The revival of folk (popular) religion in China in the last three decades has been noted in many publications and documented in ethnographic studies. However, until now there has been no quantitative study that provides an overall picture of Chinese folk‐religion practices. This article is a first attempt to draw the contours of Chinese folk religion based on three recent surveys conducted in mainland China and Taiwan. Three types of folk religion are conceptualized: communal, sectarian, and individual. Different types of folk religion may have different social functions and divergent trajectories of change in the modernization process. At present, in spite of the dramatic social, political, and cultural changes in modern times, the adherents of folk religion still substantially outnumber the believers of institutional religions in Chinese societies.
