Attachment Style Mediates the Relationship between Trauma and Somatic Distress among Individuals with Serious Mental Illness

Objective: Individuals with mental illnesses severe enough to require psychiatric hospitalization often have significant trauma histories, have developed maladaptive attachment styles, and experience comorbid somatic distress. Gaining an understanding about the interaction of such factors may lead to prioritizing interventions that target factors that mediate the relationship between trauma and adverse somatic distress. Prior research has examined various mediation models, but results have been mixed and conducted only on outpatient samples. Method: Participants (47.7% female) in a large sample (N = 2702) with a mean age of 34.62 (SD = 14.7) were enrolled in a specialist inpatient program and completed self-report measures pertaining to demographics, attachment insecurity, lifetime trauma exposure, and somatic distress within 72 hours of admission. The dimensions of attachment insecurity (i.e., attachment anxiety and attachment avoidance) were tested as parallel mediators in the relationship between lifetime trauma exposure and somatic distress. Results: The mediation analyses revealed that attachment anxiety and avoidance partially mediated the relationship between lifetime trauma exposure and somatic distress. Conclusions: These results are the first to date to implicate both attachment anxiety and avoidance as mediators between trauma exposure and somatic distress in a high acuity sample. Although the results do not imply causality, they do call attention to social-cognitive factors related to somatic distress and highlight the importance of considering attachment styles as a possible contributor to comorbid physical symptoms in patients with trauma exposure.
The Role of Consumer Engagement in Behavioral Loyalty through Value Co-Creation in Fitness Clubs

ABSTRACT Using service dominant logic as the theoretical framework, this study examines the associations between consumer engagement, two dimensions of value co-creation (co-production and value-in-use), and behavioural loyalty while considering the moderating role of psychological involvement. Participants (N = 559) were recruited from fitness clubs in Urmia, Iran. Structural equation modelling revealed positive associations between consumer engagement, value co-creation, and behavioural loyalty. consumer engagement had a positive indirect effect on behavioural loyalty through co-production, although not through value-in-use. This suggests operationalizing value co-creation as multidimensional is more appropriate than as a unitary construct. Furthermore, psychological involvement had a moderating effect on the relationship between consumer engagement and behavioural loyalty, where the relationship was stronger for individuals with higher psychological involvement. Findings from this study suggest consumer engagement is a key antecedent of behavioural loyalty and highlight the importance of co-production and psychological involvement in promoting behavioural loyalty at fitness clubs. HIGHLIGHTS Co-creation is a multidimensional construct comprising co-production and value-in-use. Co-production and value-in-use are differentially related to behavioural loyalty. Co-production mediates the relationship between consumer engagement and behaviour. Psychological involvement moderates the consumer engagement and loyalty relationship.
Women’s Empowerment Campaigns: Helpful or Harmful to the Workplace?

Women’s empowerment campaigns create greater equality for women in numerous areas including social, political, economic, and occupational fields. However, the current #MeToo and Time’s Up movements have become increasingly hostile toward men. This hostility has developed an anti-male environment that may be perceived by men as unfair restrictions on their behavior and boundaries on their autonomy. This leads to adoption of behavior and attitudes opposite of the intended effects and that may do more harm than good. This response is explained as psychological reactance. The authors discuss its harmful impact in the workplace offer suggestions for mitigating these situations.
Upper mantle structure of Mars from InSight seismic data

Single seismometer structure Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al., Knapmeyer-Endrun et al., and Stähler et al. used recently detected marsquakes from the seismometer deployed during the InSight mission to map the interior of Mars (see the Perspective by Cottaar and Koelemeijer). Mars likely has a 24- to 72-kilometer-thick crust with a very deep lithosphere close to 500 kilometers. Similar to the Earth, a low-velocity layer probably exists beneath the lithosphere. The crust of Mars is likely highly enriched in radioactive elements that help to heat this layer at the expense of the interior. The core of Mars is liquid and large, ∼1830 kilometers, which means that the mantle has only one rocky layer rather than two like the Earth has. These results provide a preliminary structure of Mars that helps to constrain the different theories explaining the chemistry and internal dynamics of the planet. Science, abf2966, abf8966, abi7730, this issue p. 434, p. 438, p. 443 see also abj8914, p. 388 Data from the InSight mission on Mars help constrain the structure and properties of the martian interior. For 2 years, the InSight lander has been recording seismic data on Mars that are vital to constrain the structure and thermochemical state of the planet. We used observations of direct (P and S) and surface-reflected (PP, PPP, SS, and SSS) body-wave phases from eight low-frequency marsquakes to constrain the interior structure to a depth of 800 kilometers. We found a structure compatible with a low-velocity zone associated with a thermal lithosphere much thicker than on Earth that is possibly related to a weak S-wave shadow zone at teleseismic distances. By combining the seismic constraints with geodynamic models, we predict that, relative to the primitive mantle, the crust is more enriched in heat-producing elements by a factor of 13 to 20. This enrichment is greater than suggested by gamma-ray surface mapping and has a moderate-to-elevated surface heat flow.
Inhibited nonradiative decay at all exciton densities in monolayer semiconductors

Straining for high photoluminescence The photoluminescence quantum yield in monolayer transition metal dichalcogenides generally drops at high emission intensities because the excitons undergo nonradiative annihilation. Kim et al. show that this process is resonantly amplified in these materials by van Hove singularities in their joint density of states. However, application of small mechanical strains (∼0.5%) shifted the van Hove singularities and suppressed the nonradiative processes. Near-unity photoluminescence quantum yield at high exciton densities was seen in exfoliated monolayers of molybdenum sulfide, tungsten sulfide, and tungsten selenide, as well as centimeter-scale tungsten sulfide monolayers grown by chemical vapor deposition. Science, abi9193, this issue p. 448 Mechanical strain shifts van Hove resonances and circumvents exciton-exciton annihilation at high photocarrier densities. Most optoelectronic devices operate at high photocarrier densities, where all semiconductors suffer from enhanced nonradiative recombination. Nonradiative processes proportionately reduce photoluminescence (PL) quantum yield (QY), a performance metric that directly dictates the maximum device efficiency. Although transition metal dichalcogenide (TMDC) monolayers exhibit near-unity PL QY at low exciton densities, nonradiative exciton-exciton annihilation (EEA) enhanced by van-Hove singularity (VHS) rapidly degrades their PL QY at high exciton densities and limits their utility in practical applications. Here, by applying small mechanical strain (less than 1%), we circumvented VHS resonance and markedly suppressed EEA in monolayer TMDCs, resulting in near-unity PL QY at all exciton densities despite the presence of a high native defect density. Our findings can enable light-emitting devices that retain high efficiency at all brightness levels.
Seismic detection of the martian core

Clues to a planet’s geologic history are contained in its interior structure, particularly its core. We detected reflections of seismic waves from the core-mantle boundary of Mars using InSight seismic data and inverted these together with geodetic data to constrain the radius of the liquid metal core to 1830 ± 40 kilometers. The large core implies a martian mantle mineralogically similar to the terrestrial upper mantle and transition zone but differing from Earth by not having a bridgmanite-dominated lower mantle. We inferred a mean core density of 5.7 to 6.3 grams per cubic centimeter, which requires a substantial complement of light elements dissolved in the iron-nickel core. The seismic core shadow as seen from InSight’s location covers half the surface of Mars, including the majority of potentially active regions—e.g., Tharsis—possibly limiting the number of detectable marsquakes.
Total-Evidence Phylogeny of the New World Polistes Lepeletier, 1836, Paper Wasps (Vespidae, Polistinae, Polistini)

ABSTRACT The genus Polistes is one of the most species-rich and widely distributed groups of social wasps and a model taxon for studies of social behavior. Almost half the Polistes world fauna occurs in the New World, but their classification has been unstable due in part to the scarcity of phylogenetic studies. We investigated the phylogeny of the New World Polistes by combining a previously existing molecular dataset with a new morphological and behavioral matrix for 90 of the 93 New World species. All analyses support a single origin for the New World Polistes. All five traditionally defined New World subgenera (Aphanilopterus, Epicnemius, Fuscopolistes, Onerarius, and Palisotius) were monophyletic, but the relationships among them varied across datasets. Our results, with an expanded phenotypic dataset, improved taxonomic sampling, and enhanced clade support relative to previous studies, strongly support a classification based on five subgenera, which are all diagnosable groups supported by clear morphological synapomorphies. Hence, we propose the revalidation of previously proposed subgenera; we provide a taxonomic account of each subgenus and an identification key to all species of New World Polistes.
Influence of Migraine on Axon Reflex-Mediated and Endothelial-Dependent Vasodilatation in the Skin

Abstract The aim of the study was to evaluate the changes in skin blood flow as a result of local heating tests in migraine patients during the interictal period, measured by laser Doppler perfusion imaging (LDI). The aim of the study was also to estimate the correlations between the results of these tests and interleukin (IL)-8 levels. Twelve migraine patients during their interictal period were compared with twelve healthy control subjects. Only women were included in the study. Both groups were matched with regard of their age, body mass index and blood pressure. For the purpose of measuring cutaneous microvascular blood flow, heating (+44 °C) of the dorsal side of the palm as a response to the local LDI was used. IL-8 was measured in serum by ELISA method. The findings suggested that migraine patients have a cutaneous vasomotor dysfunction during the interictal period. The results showed a significant decrease in the initial peak of vasodilation and the second peak of vasodilation (plateau phase). Also there were significant changes observed in the length of the time interval required to reach the first and second vasodilation peak. It is known that migraine patients have a shorter time interval to reach the first perfusion peak (axonal reflex-mediated) and longer time interval to reach the second peak (endothelium-dependent). The results confirmed the correlation between proinflammatory chemokine IL-8 levels, and the time interval till the second peak of blood flow in all study subjects.
Genetic Structure of Perch Perca Fluviatilis (L.) Populations in Latvian Rivers that are Fragmented (Daugava) and Non-Fragmented (Lielupe) By Hydroelectric Dams

Abstract Water ecosystems have an important role in maintenance of biological diversity and environmental quality in Latvia. Fish resources are one of the most valuable biological resources in Latvia. To evaluate the influence of economic activity (anthropogenic influence of cities, hydroelectric power stations) on freshwater ecosystems, the genetic structure of perch Perca fluviatilis (L.) populations in Daugava River and Lielupe River was studied. The genetic structure of the perch populations from Daugava River and Lielupe River was investigated using 9 DNA microsatellites (Pfla L4, Pfla L10, Pfla L2, Pfla L6, YP111, YP78, YP60, Svi L10, Svi L7), and by genetic diversity, the level of polymorphism, means of alleles per locus, observed and expected heterozygosity, and population structuring. It was shown that the perch population in the Daugava River in the territory of Riga was significantly different from the other populations and there was a lower level of heterozygosity in this population. In the Daugava River, genetic differentiation was significant for fish populations between Ķegums Hydroelectric Power Plant (HPP) and Riga HPP reservoirs due to the fragmentation of population by HPP dams.
Revenue Recognition and Real Earnings Management in Bosnian Construction Industry

Abstract This study explores revenue recognition and reporting expenses relevant to the stage of completion of the contract agreements. Literature suggests that the taxation effects financial reporting, realization of capital gains as well as revenue recognition. We argue that construction firms make use of these estimates to postpone revenue and value added tax recognition. The analysis grounds on the assumption that the value added tax effects timely recognition of revenues from construction agreements, where managers are incentivized to underestimating stage of completion and suppress recognition of gross earnings to better align emerging of the value tax related liability with contracted and expected inflows of cash. Results show that the revenue recognition is positively associated with reported income before tax and cost of material as a direct expense that can be allocated to the execution of construction agreements. These findings build baseline for future research that assesses effects of newly adopted standard IFRS 15 on real earnings management practice in construction industry of Bosnia and Herzegovina.
Coping With Loss: Understanding Growth and Grief in Kashmiri Students

Youth in Kashmir experience considerable loss during their formative years as a result of ongoing exposure to severe sociopolitical conflict and devastating natural disasters. This study identified the losses experienced by 204 Kashmiri college students, their adaptive and maladaptive coping strategies, and the degree to which they experienced symptoms of complicated grief and posttraumatic growth. These predominantly Muslim students relied on their faith and spiritual practices to cope with their losses. Complicated grief symptoms were associated with the number of losses experienced, the severity of associated distress, and two types of coping (meaning focused and maladaptive). In addition, posttraumatic growth was explained by the number of losses and distress, as well as coping strategy (problem focused, meaning focused, or maladaptive). We discuss clinical implications and recommendations for future research.
Social and parasocial relationships during COVID-19 social distancing

The COVID-19 pandemic provided an extraordinarily unique opportunity to investigate how sudden, involuntary alterations to social routines influenced not just social relationships, but also parasocial relationships with fictional characters and celebrities. Results from a four-wave panel survey administered during the COVID-19 pandemic (N = 166) revealed that social relationships maintained their stability during social distancing, particularly among participants who increased mediated social engagement with friends and those low in attachment anxiety. Parasocial closeness with media personae increased over time, suggesting that favorite media personae became more meaningful as participants engaged in social distancing. Parasocial closeness increased with greater intensity among participants who increased parasocial engagement, reduced face-to-face social engagement with friends, increased mediated social engagement with friends, and those low in attachment anxiety. Results are discussed in terms of the potential influence of increased mediated social engagement with real-life friends on the parasocial processing of celebrities and fictional characters.
Examining associations between COVID-19 stressors, intimate partner violence, health, and health behaviors

The economic, social, and health impacts of the COVID-19 pandemic are expected to increase the occurrence of intimate partner violence (IPV) victimization. IPV victimization may, in turn, contribute to physical and mental health, substance use, and social distancing behaviors during the COVID-19 pandemic. The primary objective of the current study was to understand the extent to which 1) COVID-19 stressors are associated with IPV victimization and 2) IPV victimization is associated with health and health behaviors. Participants (N = 1,813) completed an online survey between May 15 and 28, 2020 that assessed COVID-19 stressors (financial anxiety, social disconnection, health anxiety, COVID-19-specific stress), IPV victimization, physical and mental health, substance use, and movement outside of the home. Structural equation modeling indicated that greater COVID-19-related stressors were associated with greater IPV victimization during the pandemic, even after controlling for enduring vulnerabilities associated with IPV victimization. Additionally, greater IPV victimization during the COVID-19 pandemic was associated with higher levels of substance use and movement outside of the home, but not poorer physical and mental health. COVID-19 stressors may have detrimental relationship effects and health implications, underscoring the need for increased IPV intervention and support services during the pandemic. Findings from the current work provide preliminary correlational evidence for a theoretical model centered on IPV victimization, rather than perpetration.
Late-Holocene landscape evolution and human presence in the northern Danube delta (Chilia distributary lobes)

This paper documents the Late-Holocene environmental changes and human presence in the northern Danube delta using a multidisciplinary approach that combines geoscientific data with archaeological findings, historical texts, and maps. It follows the formation and progression of the Chilia distributary and the reconfiguration of socioeconomic activities. Sedimentary facies identified on five new cores by changes in texture properties, magnetic susceptibility, geochemistry, and macro- and microfauna composition together with the newly obtained chronology constrain the complex evolution of the Chilia branch as filling in a long-lasting bay and then of a giant lagoon (Thiagola) which covered most of the northern delta since the Old Danube lobe inception (ca. 7500 yrs BP) till modern Chilia development. It initiated during the Greek Antiquity (ca. 2500 yrs ar BP) at the delta apex, while in Roman times (ca. 1800 yrs BP) it pursued its slow flowing into the vast Thiagola Lagoon. The most dramatic transformations occurred in the last 800 years when the river passed east of the Chilia promontory, rapidly went through the present-day Matița-Merhei basin (several decades), and created its first open-sea outlet. Solid discharge increased in two distinct periods, once in the Middle Ages (ca. 750 yrs BP) and then in the Modern Period (ca. 150 yrs BP) due to human-induced land-use changes in the Danube watershed. The chronology of the cultural remains on the pre-deltaic Chilia promontory and the multiproxy analysis of a sediment core retrieved nearby downstream suggest the terrestrial connection of the island with the mainland in ancient times. The hitherto contended issue of the old Thiagola Lagoon and its location are redefined here, as are the original identifications of ancient and medieval toponyms and hydronyms, especially for Chilia-Licostomo, Byzantine, Genoese, Moldavian, Ottoman, and Russian trading point of great importance in the political and economic history of the Black Sea and neighboring regions.
Analysis of randomly damaged triangular beam lattice: elastic field and effective properties

The decay of elastic moduli of the triangular beam lattice with randomly missed links is studied. Random low-intensity damage is considered with no more than 10% of the links removed. Unidirectional and isotropic damage models are considered. Approximate analytical formulas for elastic moduli of damaged lattice are suggested and numerically verified. Models of isotropic and scalar damage are discussed; the variation of the Poisson coefficients as a result of damage is studied. Beams of different thicknesses are examined; the dependence of moduli on thickness is investigated. Random damage is simulated using a method based on the discrete Fourier transform; the mean value and standard deviation are calculated.
The sleep maths: A strong correlation between more daytime light and better night-time sleep

Lighting for workplaces and schools is typically specified to meet the needs of the visual system without sufficient regard to the lighting characteristics that are required by the human circadian system. In 2020, many workers and students were compelled by the COVID-19 pandemic to work and study from home, where light levels are typically even lower than those found in most schools and workplaces. Using online surveys, this study sought to quantify potential changes in daytime light exposures resulting from teleworking or self-isolating at home and how those changes might have affected self-reported sleep quality, psychological health and emotional health. The first survey was administered in early May 2020, and the second survey was administered in September 2020. In broad terms, our analysis indicates that the greater the amount of light one is exposed to during the day (either in the home or outdoors), the better the self-reported sleep outcomes. Stress and mood were also correlated with greater self-reported daytime light exposures. The results suggest that spending one to two hours outdoors or staying in a bright to very bright room indoors may improve night-time sleep. These results have important implications for daytime lighting in homes, offices and schools.
