Independent Effects

Abstract This study tested the independent effects and interactions of sympathetic nervous system reactivity and hostile attribution biases (HAB) in predicting change in pure and co-occurring relational bullying and victimization experiences over one year. Co-occurring and pure relational bullying and victimization experiences were measured using a dimensional bifactor model, aiming to address methodological limitations of categorical approaches, using data from 300 preschoolers (Mage = 44.70 months, SD = 4.38). Factor scores were then saved and used in nested path analyses with a subset of participants (n = 81) to test main study hypotheses regarding effects of HAB and skin conductance level reactivity (SCL-R). Bifactor models provided good fit to the data at two independent time points. HAB and SCL-R interacted to predict increases in co-occurring relational bullying/victimization with evidence for over- and underarousal pathways.

Abstract Background Research finds center-based child care typically benefits children of low socio-economic status (SES) but few studies have examined if it also reduces inequalities in developmental disadvantage. Objective I test if the length of time in center-based care between ages one and three years associates with child development scores at age three years, focusing on the impact for groups of children in the lower tercile of child development scores and in the lower SES tercile. Method Using data from 1,606 children collected in a nationally representative Chilean survey, I apply a value-added approach to measure gains in child development scores between age one and three years that are associated with length of time in center-based child care. Results Disadvantages at age one year were associated with lower child development scores at age three years. No benefits of additional time in center-based care were found for the non-disadvantaged group, but positive associations were found between more time in center-based care and child development outcomes for children with the SES disadvantage only. Center-based care was not associated with child development trajectories of children with lower child development scores at age one year, no matter their SES status. Conclusions There is evidence that Chilean center-based child care reduces SES inequality in child development scores between ages one and three years, but only if children already were not low-scorers at age one year.

We advanced several “riskier tests” of the validity of bifactor models of psychopathology, which included that the general and specific factors should be reliable and well-represented by their indicators, and that including a general factor should improve the correlated factor model’s external validity. We compared bifactor and correlated factors models using data from a community sample of youth (N=2498) whose parents provided ratings on psychopathology and external criteria (i.e., temperament, aggression, antisociality). Bifactor models tended to yield either general or specific factors that were unstable and difficult to interpret. The general factor appeared to reflect a differentially-weighted amalgam of psychopathology rather than a liability for psychopathology broadly construed. With rare exceptions, bifactor models did not explain additional variance in psychopathology symptom dimensions or external criteria compared with correlated factors models. Together, our findings call into question the validity of bifactor models of psychopathology, and the p-factor more broadly.

Abstract. Atmospheric ions participate in the formation of new atmospheric aerosol particles, yet their exact role in this process has remained unclear. Here we derive a new simple parameterization for ion-induced nucleation or, more precisely, for the formation rate of charged 2-nm particles. The parameterization is semi-empirical in the sense that it is based on comprehensive results of one-year-long atmospheric cluster and particle measurements in the size range ∼1–42 nm within the EUCAARI (European Integrated project on Aerosol Cloud Climate and Air Quality interactions) project. Data from 12 field sites across Europe measured with different types of air ion and cluster mobility spectrometers were used in our analysis, with more in-depth analysis made using data from four stations with concomitant sulphuric acid measurements. The parameterization was given in two slightly different forms: a more accurate one that requires information on sulfuric acid and nucleating organic vapor concentrations, and a simpler one in which this information is replaced with the global radiation intensity. In principle, these new parameterizations are applicable to all large-scale atmospheric models containing size-resolved aerosol microphysics.

The idea that human males are most strongly attracted to traits that peak in women in the nubile age group raises the question of how well women in that age group contend with the potential hazards of a first pregnancy. Using data for 1.7 million first births from 1990 U.S. natality and mortality records, we compared outcomes for women with first births (primiparas) aged 16–20 years (when first births typically occur in forager and subsistence groups) with those aged 21–25 years. The younger primiparas had a much lower risk of potentially life-threatening complications of labor and delivery and, when evolutionarily novel risk factors were controlled, fetuses which were significantly more likely to survive despite lower birth weights. Thus, nubile primiparas were more likely to have a successful reproductive outcome defined in an evolutionarily relevant way (an infant of normal birth weight and gestation, surviving to one year, and delivered without a medically necessary cesarean delivery). This suggests that prior to the widespread availability of surgical deliveries, men who mated with women in the nubile age group would have reaped the benefit of having a reproductive partner more likely to have a successful first pregnancy.

National Trends

Introduction: As the US population ages and indications for cardiac device implantation expand, there is a concomitant increase in patients undergoing lead removal/extraction (LR/E).. We sought to examine trends in outcomes and complications associated with LR/E. Methods: We conducted a retrospective analysis using data from a large U.S. commercial insurance database (privately insured and Medicare Advantage patients) identifying all patients undergoing LR/E between 2004 and 2013 with at least one year continuous medical plan enrollment prior to LR/E (to identify baseline comorbidities). Using ICD9 codes and CPT codes, major complications (hemorrhage requiring transfusion, vascular injury, pericardial complications, respiratory complications, cerebrovascular complications, and requirement for cardiac surgery) associated with LR/E and 30-day readmission rates were evaluated. Results: Among 42,878 patients who underwent LR/E (median age of 62 ( 54, 72) years, 70% male); approximately 1 in 40 experienced a major adverse event (2.4%) during the study period. Respiratory complications were the most common complication and 311 patients required cardiac surgery. 30-day readmission occurred in 11.1% of the total population. The most common reasons for readmission were heart failure exacerbation (18.7%) and device related complications (13.2%). Conclusion: The observed complication rates after LE/R in clinical practice are similar to those seen in recent clinical trials and have been relatively stable over the past 10 years.

The Impact

The Internet has a significant influence on poverty alleviation and economic growth. Internet involvement in small-medium enterprises (SMEs) has the opportunity to create a better level of welfare. Using data from the fifth wave of the Indonesian Family Life Survey (IFLS), this study aims to analyze the impact of internet utilization on household welfare among two groups, household enterprises with internet use for business and without internet use for business. The results of the Propensity Score Matching (PSM) method mention that household enterprises with internet for business purposes have higher household per capita expenditure, food consumption, and non-food expenditure than household enterprises without internet use. Another interesting result finds that household enterprises are likely to use the internet only if household heads at a young age and business establish less than one year.

<p>Bifactor models have gained increasing popularity in the literature concerned with personality, psychopathology and assessment. Empirical studies using bifactor analysis generally judge the estimated model using SEM model fit indices, which may lead to erroneous interpretations and conclusions. To address this problem, several researchers have proposed multiple criteria to assess bifactor models, such as a) conceptual grounds, b) overall model fit indices, and c) specific bifactor model indicators. In this article, we provide a brief summary of these criteria. An example using data gathered from a recently published research article is also provided to show how taking into account all criteria, rather than solely SEM model fit indices, may prevent researchers from drawing wrong conclusions.</p>

AbstractIn this study, we explored the effects of mentor and mentee insecure attachment dispositions (ambivalence and avoidance) on mentoring relationship quality while considering the specific nature of the interactive mentoring context. Participants (N = 252 matches) were enrolled in the MIRES program, a one-year college-based mentoring program that matches late adolescent mentees (17-year-olds) with young adult mentors (23-year-olds), designed to facilitate the transition to college. Using data drawn from mentors’ logbooks (at nine time points), two interactive contexts were addressed: (1) situations involving mentee academic issues and mentor proactive academic support (academically oriented), and (2) situations involving mentee personal issues and mentor emotional support, and caring (emotionally oriented). Linear regression results showed that both mentors’ and mentees’ avoidance uniquely predicted lower reports of mentoring relationship quality, but especially in emotionally oriented matches and when their partners’ attachment ambivalence was high. In matches less focused on emotional support, mentors’ attachment avoidance interacted with mentees’ ambivalence to predict positive mentoring relationship quality. Theoretical, practical, and mentor training issues are discussed.

Objective Using data from 40 years of national surveys of UK medical graduates, we report on ophthalmology as a career choice. Design, setting, and participants Self-administered questionnaire surveys of all graduates from all UK medical schools in selected years of qualification between 1974 and 2015. Main outcome measures Career specialty preferences of doctors one, three, and five years after graduation; career specialty destinations 10 years after graduation. Results One year after graduation, ophthalmology was the first career preference of 1.6% of the qualifiers of 1974–83, 2.2% of 1993–2002, and 1.8% of 2005–15. The corresponding percentages three years after graduation were 1.5, 1.8, and 1.2%. Men were more likely than women to choose ophthalmology: among graduates of 2005–15, 2.4% of men and 1.4% of women did so at one year, as did 1.7% of men and 0.7% of women at five years. Seventy per cent of doctors practising as ophthalmologists 10 years after qualification had told us in their first post-qualification year that ophthalmology was their first choice of career. Conclusions There has been no systematic change in recent years in the proportion of recent medical graduates intending to have a career in ophthalmology when surveyed one year after graduation. However, the proportion at three and five years after graduation was lower than that at year 1. Suggestions for maintaining interest in the specialty include improved career advice, greater early clinical exposure to ophthalmology, and improved access to flexible training. Most practising ophthalmologists had made early decisions that this was their intended career.
