Firefighters: The emotional processing of physiological risks

This presentation acknowledges the deficiency and necessity for research regarding emotional processing of firefighters at risk of developing cancer due to occupational risk. The developing research project will use qualitative methodology to gather and investigate subjective detailed descriptions of firefighters\u27 psychological experiences regarding occupational risk. Because the goal of this project is to identify explanatory concepts of emotional processing, we will follow a grounded theory approach. Participants, a minimum of six firefighters, will undergo in-person interviews based on three open-ended questions. All interviews will be audio recorded, transcribed, coded, and analyzed for similar themes and patterns

A review of collaborative biopsychosocial healthcare worldwide

This review calls attention to the importance of collaborative care in international settings and highlight advances in models of care that are emerging globally. As our understanding of physical and mental health increases, healthcare continues to move towards a systemic approach to the mind-body dichotomy. This shift has resulted in increased provider collaboration and formation of multidisciplinary healthcare organizations. We propose that collaborative care is an effective way for providers to meet the physical and mental healthcare needs of patients across cultures. We further propose categorizing collaborative care models on a continuum of the degree of physical and functional integration

Mindful marriage: Exploring the interaction between mindfulness and length of marriage

The purpose of this study was to explore the interaction between length of marriage and trait mindfulness on marital satisfaction. Although previous research has demonstrated that both length of marriage and trait mindfulness positively predict marital satisfaction, research has yet to explore the interaction between the two. Thus, our study adds to the existing literature by exploring the relationship between length of marriage and marital satisfaction, moderated by mindfulness. Because mindfulness has been shown to both act as a buffer against stress and to have a positive relationship with marital satisfaction, we hypothesized that trait mindfulness would moderate the relationship between length of marriage and marital satisfaction. More specifically, we hypothesized that (a) length of marriage would positively predict marital satisfaction, and (b) mindfulness would moderate this relationship, such that those in short-term marriages who are high in trait mindfulness will demonstrate higher marital satisfaction than those in both long and short-term marriages with low trait mindfulness. Participants (N = 331) indicated how long they had been married and then completed measures of mindfulness (FFMQ-SF) and marital satisfaction (KMSS). Results indicated that neither trait mindfulness nor length of marriage predicted marital satisfaction. Moreover, contrary to our hypothesis, the interaction between length of marriage and trait mindfulness was also nonsignificant. Follow-up analyses indicated significant differences in trait mindfulness, but not marital satisfaction between groups. Limitations of the current study and implications for future research in this area are discussed

Learning to have a voice: The spouse\u27s experience of clergy sexual misconduct

In the present study, researchers utilized a systemic approach to examine the qualitative experiences of the spouses of religious leaders who engaged in sexual misconduct. Data was collected and analyzed through a process of narrative inquiry using in-depth, semi-structured interviews. Multiple rounds of consensus-based coding led to an eco-systemic framework for organizing and analyzing data. Participant descriptions of their experience were organized according to chronology and bio-psycho-social systemic level: intrapersonal, interpersonal, and contextual. These findings highlight the systemic risk factors for sexual misconduct and the need for interventions that extend beyond individuals to address marital, familial, and communal distress

An Autocatalytic System of Photooxidation-Driven Substitution Reactions on a Fe^II₄L₆Cage Framework

The functions of life are accomplished by systems exhibiting nonlinear kinetics: autocatalysis, in particular, is integral to the signal amplification that allows for biological information processing. Novel synthetic autocatalytic systems provide a foundation for the design of artificial chemical networks capable of carrying out complex functions. Here we report a few Feᴵᴵ₄L₆ cages containing BODIPY chromophores having tuneable photosensitizing properties. Electron-rich anilines were observed to displace electrondeficient anilines at the dynamic-covalent imine bonds of these cages. When iodoaniline residues were incorporated, heavy-atom effects led to enhanced ¹O₂ production. The incorporation of (methylthio)aniline residues into a cage allowed for the design of an autocatalytic system: oxidation of the methylthio groups into sulfoxides make them electron-deficient and allows their displacement by iodoanilines, generating a better photocatalyst and accelerating the reaction.This work was funded by the European Research Council (259352).This is the author accepted manuscript.

Temperature Controls Guest Uptake and Release from Zn4L4 Tetrahedra.

We report the preparation of triazatruxene-faced tetrahedral cage 1, which exhibits two diastereomeric configurations (T1 and T2) that differ in the handedness of the ligand faces relative to that of the octahedrally coordinated metal centers. At lower temperatures, T1 is favored, whereas T2 predominates at higher temperatures. Host-guest studies show that T1 binds small aliphatic guests, whereas T2 binds larger aromatic molecules, with these changes in binding preference resulting from differences in cavity size and degree of enclosure. Thus, by a change in temperature the cage system can be triggered to eject one bound guest and take up another.This work was supported by the European Research Council (695009) and the UK Engineering and Physical Sciences Research Council (EPSRC EP/M008258/1).

Glucose Binding Drives Reconfiguration of a Dynamic Library of Urea-Containing Metal-Organic Assemblies.

A bis-urea-functionalized ditopic subcomponent assembled with 2-formylpyridine and FeII , resulting in a dynamic library of metal-organic assemblies: an irregular FeII4 L6 structure and three FeII2 L3 stereoisomers: left- and right-handed helicates and a meso-structure. This library reconfigured in response to the addition of monosaccharide derivatives, which served as guests for specific library members, and the rate of saccharide mutarotation was also enhanced by the library. The (P) enantiomer of the FeII2 L3 helical structure bound β-D-glucose selectively over α-D-glucose. As a consequence, the library collapsed into the (P)-FeII2 L3 helicate following glucose addition. The α-D-glucose was likewise transformed into the β-D-anomer during equilibration and binding. Thus, β-D-glucose and (P)-3 amplified each other in the product mixture, as metal-organic and saccharide libraries geared together into a single equilibrating system.European Research Council (695009), UK Engineering and Physical Sciences Research Council (EPSRC EP/P027067/1), National Natural Science Foundation of China (No. 21971210), Natural Science Foundation of Shaanxi Province (2019KJXX-062) and the Chinese Scholarship Council (CSC), the Alexander von Humboldt Foundation for a Feodor Lynen Research Fellowship, the Rashkind Family Endowment, the Chenery Endowment, and the Donors of the American Chemical Society Petroleum Research Fun

A measurement of the energy spectra of cosmic rays from 20 to 1000 GeV per amu

A group collaboration was made in the development of the Bristol University Gas Spectrometer number 4 (BUGS 4). The BUGS 4 detector is designed to measure the charge spectrum for species between oxygen and the iron peak as a function of energy per nucleon, between 20 and 1000 GeV/amu. It is particularly concerned with energies above 50 GeV/amu. The high energy component is considerably less affected by propagation through the interstellar medium than the lower energy component and is expected to approach the original charge spectrum of the source more closely. This information allows one to unravel the effects of cosmic ray production, acceleration, and propagation. The detector is described in total detail. The method of estimating the charge and energy of a cosmic ray depends on the energy of the particle. Calculations and experiments lead to the expectation of a nearly constant charge resolution of about 0.2 charge units over the whole energy range except 4.5 less than gamma less than 20. In this band, the experiment is insensitive to energy. A balloon flight is planned in 1993

Coordination Cages Selectively Transport Molecular Cargoes Across Liquid Membranes.

Chemical purifications are critical processes across many industries, requiring 10-15% of humanity's global energy budget. Coordination cages are able to catch and release guest molecules based upon their size and shape, providing a new technological basis for achieving chemical separation. Here, we show that aqueous solutions of FeII4L6 and CoII4L4 cages can be used as liquid membranes. Selective transport of complex hydrocarbons across these membranes enabled the separation of target compounds from mixtures under ambient conditions. The kinetics of cage-mediated cargo transport are governed by guest binding affinity. Using sequential transport across two consecutive membranes, target compounds were isolated from a mixture in a size-selective fashion. The selectivities of both cages thus enabled a two-stage separation process to isolate a single compound from a mixture of physicochemically similar molecules
