County-level hurricane exposure and birth rates: application of difference-in-differences analysis for confounding control

Abstract Background Epidemiological analyses of aggregated data are often used to evaluate theoretical health effects of natural disasters. Such analyses are susceptible to confounding by unmeasured differences between the exposed and unexposed populations. To demonstrate the difference-in-difference method our population included all recorded Florida live births that reached 20 weeks gestation and conceived after the first hurricane of 2004 or in 2003 (when no hurricanes made landfall). Hurricane exposure was categorized using ≥74 mile per hour hurricane wind speed as well as a 60 km spatial buffer based on weather data from the National Oceanic and Atmospheric Administration. The effect of exposure was quantified as live birth rate differences and 95 % confidence intervals [RD (95 % CI)]. To illustrate sensitivity of the results, the difference-in-differences estimates were compared to general linear models adjusted for census-level covariates. This analysis demonstrates difference-in-differences as a method to control for time-invariant confounders investigating hurricane exposure on live birth rates. Results Difference-in-differences analysis yielded consistently null associations across exposure metrics and hurricanes for the post hurricane rate difference between exposed and unexposed areas (e.g., Hurricane Ivan for 60 km spatial buffer [−0.02 births/1000 individuals (−0.51, 0.47)]. In contrast, general linear models suggested a positive association between hurricane exposure and birth rate [Hurricane Ivan for 60 km spatial buffer (2.80 births/1000 individuals (1.94, 3.67)] but not all models. Conclusions Ecological studies of associations between environmental exposures and health are susceptible to confounding due to unmeasured population attributes. Here we demonstrate an accessible method of control for time-invariant confounders for future research

The position of authenticity within extant models of personality.

The aim of the current study was to explore where authenticity, derived from the humanistic tradition of psychology, was positioned within a number of extant models of personality. Exploratory and Confirmatory Factor Analysis of data from four samples (total N = 1286) suggested that authenticity can be considered as loading on the Honesty–Humility factor of personality. These findings are discussed in terms of the wider theoretical overlaps between Honesty–Humility and psychological functioning as emphasised by the humanistic tradition of psychology

Absorbent particles, especially catamenials, having improved fluid directionality, comfort and fit

Absorbent articles, especially sanitary napkins, contain fibers with intra-fiber capillary channels. In-use, the capillary channel fibers direct menses to a storage layer, thereby minimizing product failure and staining of undergarments. The capillary channel fibers can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges

The personal self of psychotherapists : Dimensions, correlates, and relations with clients

ObjectiveThe personal self of psychotherapists, that is, experiences of self in close personal relationships and its association with therapists' individual and professional attributes is explored. The study aimed to: (a) describe therapists' self-ratings on specific self-attributes; (b) determine their dimensionality; (c) explore demographic, psychological, and professional correlates; and (d) assess the convergence with professional self. MethodData from the Development of Psychotherapists Common Core Questionnaire were available for>10,000 psychotherapists of various professions, theoretical orientations, career levels, and nations. ResultsMost psychotherapists described themselves in close relationships in affirming terms (e.g., warm/friendly), although a substantial minority also described themselves in negative terms. Factor analyses yielded four dimensions: Genial/Caring, Forceful/Exacting, Reclusive/Remote, and Ardent/Expressive. Being Genial/Caring was associated with life satisfaction. Among professional attributes, personal self-experiences, and parallel dimensions of relationship with clients correlated strongly. ConclusionsAnalyses of>10,000 psychotherapists revealed meaningful variations in personal self relevant to personal and professional life.Peer reviewe

Post-Disaster Reproductive Health Outcomes

We examined methodological issues in studies of disaster-related effects on reproductive health outcomes and fertility among women of reproductive age and infants in the United States (US). We conducted a systematic literature review of 1,635 articles and reports published in peer-reviewed journals or by the government from January 1981 through December 2010. We classified the studies using three exposure types: (1) physical exposure to toxicants; (2) psychological trauma; and (3) general exposure to disaster. Fifteen articles met our inclusion criteria concerning research focus and design. Overall studies pertained to eight different disasters, with most (n = 6) focused on the World Trade Center attack. Only one study examined pregnancy loss, i.e., occurrence of spontaneous abortions post-disaster. Most studies focused on associations between disaster and adverse birth outcomes, but two studies pertained only to post-disaster fertility while another two examined it in addition to adverse birth outcomes. In most studies disaster-affected populations were assumed to have experienced psychological trauma, but exposure to trauma was measured in only four studies. Furthermore, effects of both physical exposure to toxicants and psychological trauma on disaster-affected populations were examined in only one study. Effects on birth outcomes were not consistently demonstrated, and study methodologies varied widely. Even so, these studies suggest an association between disasters and reproductive health and highlight the need for further studies to clarify associations. We postulate that post-disaster surveillance among pregnant women could improve our understanding of effects of disaster on the reproductive health of US pregnant women

Absorbent articles, especially catamenials, having improved fluid directionality

The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels

Sextupole RDTs in the LHC at injection and in the ramp

During 2023, examination of the action dependence of sextupolar resonance driving terms (RDT) in the LHC at injection, as measured with an AC-dipole, demonstrated that a robust measurement of the RDTs could still be achieved even with very small amplitude kicks, typically used for linear optics studies. Consequently, analysis of optics measurements from 2022 to 2024 during the LHC energy ramp allowed a first measurement of the sextupole resonance evolution. A large asymmetry was observed between the two LHC beams, with the clockwise circulating beam (LHCB1) being significantly worse than the counter-clockwise circulating beam (LHCB2), and a clear increase in the RDT strength during the ramp was observed. During 2024 commissioning, a first attempt was made to correct the 1020 RDT of LHCB1 at injection. Results are presented in this report

Unconditional positive self-regard, intrinsic aspirations and authenticity: pathways to psychological well-being

Unconditional positive self-regard (UPSR) is regarded by humanistic psychologists as an important determinant of well-being. However, until recently it has received little empirical attention. The current study aims to examine the association between unconditional positive self-regard and several key constructs consistent with the ideas of well-being within contemporary positive psychology. Study 1 is a confirmatory factor analysis of the UPSR scale. The statistically significant best fit for the data was a related two-factor model. Study 2 used the two-factors of the UPSR scale to explore the association with intrinsic aspirations. The study showed positive self-regard was statistically significantly positively correlated with the intrinsic aspirations total scale and with each of the separate scores for IA-importance and IA-chance. Unconditionality of regard was statistically significantly negatively correlated with IA-importance but was not statistically significantly correlated to either the IA-total or IA-chance scores. Study 3 considers the association between UPSR, intrinsic aspirations and authenticity. Unconditionality of regard was statistically significantly positively correlated with the authenticity scale score. Only IA-chance scores showed a statistically significant and positive correlation with authenticity. The remaining correlations between intrinsic aspirations and authenticity were not statistically significant. Results call for further empirical attention to UPSR within positive psychology research

Understanding Face and Shame: A Servant-Leadership and Face Management Model

Clergy can have a negative impact on churches and other individuals when they knowingly or unknowingly attempt to save face, that is, try to protect their standing or reputation. The desire to gain face and the fear of losing face and feeling ashamed will likely permeate clergy’s decision-making processes without even being noticed. This study explores the essence of face and face management and the relationship between face management and two characteristics of servant-leadership—awareness and healing—in both Chinese and American churches through the methodology of hermeneutic phenomenology. Prior to this study, to my knowledge, no hermeneutic phenomenological research of face management has been conducted in a church setting. Through a review of the literature, four areas are explored: face and shame, face management, servant-leadership, and face, shame, and face management within the church. This study obtained approval from the Institutional Review Board and informed consent from the participants. Three Chinese and three American Christian ministers were chosen to complete a question sheet and participate in two semi-structured interview sessions. A first cycle of open coding and second cycle of pattern coding were used during data analysis. Face experiences are discussed in light of eight major themes: body, triggers, becoming, face concepts, strategies, emotions, servant-leadership, and the church. Findings from the study help build a servant-leadership and face management model, which can offer an anchored approach for clergy and pastoral counselors to address face and shame and to develop therapeutic interventions
