TiO2 nanoparticles (TiO2 NPs) are employed in many products (paints, personal care products, especially sunscreens, plastics, paper, water potabilization and food products) and are then released into the environment from these products. These nanoparticles present potential risk to freshwater and marine microalgae. The primary toxicity mechanism is adsorption between NPs and microalgae (heteroagglomeration); however, studies of interactions of this kind are scarce. We investigated the heteroagglomeration process that occurs between two forms of TiO2 material, nanoparticles and bulk, and three different microalgae species, and under different environmental conditions (freshwater and marine water), in order to assess the influence of pH and ionic strength (IS)...

OBJECTIVE: To gain insights into the problems of dual sensory impaired older adults in long-term care. Insights into these problems are essential for developing adequate policies which address the needs of the increasing population of dual sensory impaired older adults in long-term care. METHODS: A qualitative study was conducted in parallel with a cluster randomized controlled trial. Dual sensory impaired older adults in the intervention group (n = 47, age range 82-98) were invited by a familiar nurse to identify the problems they wanted to address...

Some people with DID, despite years of DID-specific therapy (using the three-phase approach, ISSTD, 2011), seem unable to get better. In particular, they seem unable to remain physically safe ("Phase One") and report continued exposure to abuse. As every fresh hurt causes fresh dissociation, their DID becomes further entrenched over time. Moreover, as dissociation makes the person more vulnerable to being re-abused, they become caught up in a vicious cycle, which further obstructs their efforts toward recovery...

OBJECTIVE: Emotional disorders and alcohol use disorders (AUDs) frequently demonstrate significant 12-month and lifetime comorbid associations. This comorbidity has been incorporated into influential theories of addiction processes that posit direct or indirect causal associations between these disorder categories. There is currently no consensus, however, about the sequencing of these disorders. In this research, longitudinal data from a regionally representative community sample were used to evaluate whether emotional disorders constitute a proximal antecedent, concomitant, or short-term consequence of first episode (or index) AUDs...

Clinical discussion groups based on the Three-Level Model for Observing Patient Transformations (3-LM) enable us to reflect on the clinical common ground shared by psychoanalysts who have different theoretical frameworks. The very existence of this common ground is controversial. While analysts such as Wallerstein support it, others, like Green, think it is just a myth. In their 2005 controversy Wallerstein and Green proposed an observation procedure that might clarify this matter. This procedure bears great similarity to the one used by clinical discussion groups that apply the 3-LM...

The influence of nannies and other significant caregivers on a child's psychological and emotional development may be profound and if unrecognized may contribute to psychopathology in adulthood. However, the significance of the nanny has been relatively neglected within the psychoanalytic literature. In this paper I will discuss the impact of early caregivers other than the biological mother on the psychic development of the child, and the role of the nanny within the family dynamics as a figure attracting powerful unconscious phantasies and unwanted projections...

The importance of emotions within medical practice is well documented. Research suggests that how clinicians deal with negative emotions can affect clinical decision-making, health service delivery, clinician well-being, attentiveness to patient care and patient satisfaction. Previous research has identified the transition from student to junior doctor (intern) as a particularly challenging time. While many studies have highlighted the presence of emotions during this transition, how junior doctors manage emotions has rarely been considered...

PURPOSE: To assess short-term effects of daily worries on hypothalamic-pituitary-adrenal axis activity and later implications for adolescents' health symptoms. We hypothesized that heightened worry would be associated with stronger next-morning cortisol awakening response (CAR) to prepare the body for the demands of the upcoming day. Guided by biological adaptation to stress theories, we also hypothesized that dysregulated CAR would heighten associations between worries and later health symptoms, while also testing direct associations between worries and dysregulated CAR and health...

In this study, we explored item and person parameter recovery of the four-parameter model (4PM) in over 24,000 real, realistic, and idealized data sets. In the first analyses, we fit the 4PM and three alternative models to data from three Minnesota Multiphasic Personality Inventory-Adolescent form factor scales using Bayesian modal estimation (BME). Our results indicated that the 4PM fits these scales better than simpler item Response Theory (IRT) models. Next, using the parameter estimates from these real data analyses, we estimated 4PM item parameters in 6,000 realistic data sets to establish minimum sample size requirements for accurate item and person parameter recovery...

BACKGROUND: Substance use before and during sexual activity is associated with many negative health outcomes. Estimates suggest that at least 4.3 million American adults annually engage in regular sex-related alcohol consumption, indicating that the intersection of substance use and sexual behavior is of public health concern. However, it is likely that when considering broader sex-related substance use, estimates would be notably higher. While substance use disorders and antisocial personality disorder have been associated with sex-related alcohol consumption, no study has investigated how regular sex-related substance use is associated with the broader transdiagnostic externalizing spectrum...

Measurement precision often fluctuates across latent trait continuums. Plots of test information are typically provided in item response theory (IRT) investigations, but the numerical values for test information are not readily interpretable. This article draws attention to the important, nonlinear relationships between test information, location-specific standard errors of measurement, and location-specific reliability. It provides a method for examining the attenuation in effect sizes (correlations) that is caused by fluctuating levels of measurement error...

Although sport involvement has the potential to enhance psychological wellbeing, studies have suggested that motivation to participate in sports activities declines across childhood and adolescence. This study incorporated expectancy-value theory to model children's sport ability self-concept and subjective task values trajectories from first to twelfth grade. Additionally, it examined if sport motivation trajectories predicted individual and team-based sport participation and whether sport participation in turn reduced the development of depressive symptoms...

Advanced oxidation processes (AOPs) are widely used in wastewater treatment of pharmaceutical and personal care products (PPCPs). In this work, the OH-initiated transformation as well as the hydrolysis of a typical PPCPs, aspirin, was investigated using density functional theory (DFT) calculations and laboratory experiments. For DFT calculations, the frontier electron densities and bond dissociation energies were analyzed. Profiles of the potential energy surface were constructed, and all the possible pathways were discussed...

MaƂgorzata Fajkowska
Personality science has always been and is still ready for new theorizing on traits. Accordingly, this paper presents the recently proposed Traits as Hierarchical Systems (THS) model, where personality traits are not only the emergent properties of the three-level hierarchy of the personality system, but are also hierarchical per se. As hierarchical systems, they are organized into three levels: mechanisms and processes, structures, and behavioral markers. In this approach trait denotes the underlying, recurrent mechanisms that pattern its structure and account for the stability/variability of individual characteristics...

There is growing attention to the training and education of Personal Support Workers, or PSWs, who work in community, home and long-term care settings supporting older people and people with disabilities. In Ontario, Canada, amid a volatile policy landscape, the provincial government launched an effort to standardise PSW education. Using qualitative methods, this study considered the question: What are the central educational issues reflected by students, working PSWs and key informants, and are they addressed by the PSW programme and training standards? Phase one was a public domain analysis completed between January and March 2014 and updated for major developments after that period...

People sometimes disagree about who owns which objects, and these ownership dilemmas can lead to costly disputes. We investigate the cognitive mechanisms underlying people's judgments about finder versus landowner cases, in which a person finds an object on someone else's land. We test psychological hypotheses motivated directly by three major principles that govern these cases in the law. The results show that people are more likely to favor the finder when the object is in a public space compared to a private space...

Objective: After adoption of the National Competency-based Learning Objectives Catalogue in Medicine [Nationaler Kompetenzbasierter Lernzielkatalog Medizin, NKLM], the German medical faculties are asked to test the learning obejctives recorded in it and evaluate them critically. The faculties require curricular transparency for competence-oriented transition of present curricula, which is best achieved by systematic curriculum mapping in comparison to the NKLM. Based on this inventory, curricula can be further developed target-oriented...

BACKGROUND: There are thousands of fitness-related smartphone applications ("apps") available for free and purchase, but there is uncertainty if these apps help individuals achieve and maintain personal fitness. Technology usage attrition is also a concern among research studies on health technologies. METHODS: Usage of three fitness apps was examined over 5 months to assess adherence and effectiveness. Initially, 64 participants downloaded three free apps available on Android and iOS and 47 remained in the study until posttest...

Matthew Boden, Adrienne Heinz, Todd B Kashdan
BACKGROUND: People commonly use psychoactive substances to increase physical and psychological pleasure. Neuroadaptations in the brain's reward system coupled with changes in social functioning and networking resulting from chronic substance use impede the ability to derive pleasure from non-substance related activities. OBJECTIVE: We elucidate and validate the hypothesis that treatments for substance use disorders would potentially have a stronger and broader impact by helping recipients to experience pleasure as part of an expansive focus of increasing adaptive functioning, well-being, and personal fulfillment and actualization...

PURPOSE: Knowledge on what contributes to job satisfaction of people with intellectual disabilities is limited. Using self-determination theory, we investigated whether fulfillment of basic psychological needs (i.e., autonomy, relatedness, competence) affected job satisfaction, and explored associations between workplace participation, need fulfillment and job satisfaction. METHOD: A total of 117 persons with intellectual disabilities, recruited from a Dutch care organization, were interviewed on need fulfillment at work and job satisfaction...
