Advancing the social identity approach to health and well‐being: Progressing the social cure research agenda
Authors: Jetten Jolanda , Haslam S. Alexander , Cruwys Tegan , Greenaway Katharine H. , Haslam Catherine , Steffens Niklas K. 
Published: October 2017

AbstractThe health of people's body and mind is powerfully conditioned by social factors that affect their social identity. Consistent with this notion, there is a growing interest in the way that group memberships (and the social identities derived from belonging to these groups) affect health and well‐being. To the extent that group memberships provide individuals with meaning, support, and agency (i.e., a positive sense of social identity), health is positively impacted, constituting a “social cure”. However, when group membership is not associated with these positive psychological resources or when social identity is challenged in other ways (e.g., group membership is devalued or stigmatised), social identities may become a curse, threatening and potentially harming health and well‐being. In a range of social contexts, novel examples of these processes are brought together in the contributions to this special issue. In this editorial, we link the findings from these contributions to a set of hypotheses that emerge from the social identity approach to highlight the nuanced ways in which social identity processes are key to understanding health and well‐being (Haslam, Jetten, Cruwys, Dingle, & Haslam, forthcoming). The contributions in this special issue point to fruitful ways to develop the social cure agenda. Together they highlight the importance of social identities as powerful psychological resources that have an important role to play in managing and improving health.

Published: October 2017

ObjectiveTo examine associations among substance use disorder (SUD) and measures of length of stay (LOS) and non‐psychiatric medical comorbidity (MEDCO) in older‐adult inpatients with serious mental illness (SMI), hypothesizing SUD would be related to worse clinical outcomes.MethodsA cross‐sectional study analyzed medical records from 2010 to 2016 of 7258 inpatients with SMI ≥ age 50, obtained from a 274‐bed psychiatric hospital. Descriptive analyses examined prevalence rates for SUD status (+/−), individual drug classes, and total number of SUDs (polysubstance use disorders). Regression models examined the influence of 2 independent variables of interest: (1) SUD status (+/−) and (2) type of SUD (ie, specific drug), controlling for demographic factors and additional (non‐SUD) psychiatric disorders. Two dependent (outcome) variables were examined: LOS and MEDCO.ResultsThe overall SUD rate was 26%; cocaine was the most common SUD (≈ 10%). SUD status and additional (non‐SUD) psychiatric diagnoses were significantly associated with longer LOS (both P < 0.001). For individual SUDs, cocaine, marijuana, opiates, and alcohol were all significantly associated with LOS (all P < 0.01). SUD status, age, sex, admission status, and race were significantly associated with MEDCO (all P < 0.002). For individual SUDs, barbiturates, opiates, and alcohol were all significantly associated with MEDCO (P < 0.01).ConclusionsThe prevalence of SUD in this sample underscores concerns related to treating older adults presenting providers with comorbid SUD and SMI. This combination may increase the burden and complexity of care, warranting further investigation into mechanisms and long‐term consequences.
Changing Perspectives on the Strategic Use of Microwave Heating in Organic Synthesis

Published: October 2017

AbstractThis Personal Account describes collaborative investigations into apocryphal microwave effects in organic chemistry. Focused research on microwave‐assisted organic synthesis has been fraught with confusion, controversy, and misinformation. Microwave heating is an undoubtedly useful tactic for organic synthesis, but whether or not it can offer strategic advantages remains an open question in the minds of many people. (Ironically, those who do not consider it an open question are split as to whether it has been resolved affirmatively or negatively.) Our research in this area is guided by the hypothesis that microwave heating can alter reaction kinetics in ways distinct from what is observable under conventional heating. Here we provide a succinct record of the origins of our interests, our initial queries and associated controversies, and recent efforts to identify, quantify, and begin to leverage selective microwave heating for strategic advantage in organic synthesis.
Hospital Surge Capacity: A Web-Based Simulation Tool for Emergency Planners

Published: October 2017

AbstractThe National Center for the Study of Preparedness and Catastrophic Event Response (PACER) has created a publicly available simulation tool called Surge (accessible at http://www.pacerapps.org) to estimate surge capacity for user-defined hospitals. Based on user input, a Monte Carlo simulation algorithm forecasts available hospital bed capacity over a 7-day period and iteratively assesses the ability to accommodate disaster patients. Currently, the tool can simulate bed capacity for acute mass casualty events (such as explosions) only and does not specifically simulate staff and supply inventory. Strategies to expand hospital capacity, such as (1) opening unlicensed beds, (2) canceling elective admissions, and (3) implementing reverse triage, can be interactively evaluated. In the present application of the tool, various response strategies were systematically investigated for 3 nationally representative hospital settings (large urban, midsize community, small rural). The simulation experiments estimated baseline surge capacity between 7% (large hospitals) and 22% (small hospitals) of staffed beds. Combining all response strategies simulated surge capacity between 30% and 40% of staffed beds. Response strategies were more impactful in the large urban hospital simulation owing to higher baseline occupancy and greater proportion of elective admissions. The publicly available Surge tool enables proactive assessment of hospital surge capacity to support improved decision-making for disaster response.

Conceptualizations of suicide through time and socio-economic factors: a historical mini-review
Authors: Solano P. , Pizzorno E. , Pompili M. , Serafini G. , Amore M. 
Published: October 2017

ObjectivesSuicide is a complex phenomenon determined by the interplay of an articulated network of factors including socio-economic factors which have a decisive role. This paper investigates the development of the modern conceptualization of suicide in Europe, its sociological understandings and its intertwinement with economic cycles throughout time.MethodsMEDLINE, SCHOLAR, EMBASE using the keywords ‘socioeconomic factors AND suicide’; ‘economic cycles AND suicide’; ‘history AND suicide’ without timeframe limitations. Moreover, journal-by-journal search in journals of related areas was performed.ResultsIn total, 51 historical studies focusing on the subjects in European countries were included. Three main areas arose: (a) development of the conceptualization of suicide over time; (b) sociological understandings of suicide according to the structure of society and its economy of power; (c) economic theories explaining the intertwinement of economic cycles and suicides.ConclusionsSuicide is a deeply human phenomenon inescapably linked to and grounded in society and economic cycles. Understandings from the past show the importance of accurate analysis of socio-economic contexts that shape societies together with man’s own sense of self in order to organize multi-layered tangible and intangible support strategies to better understand and prevent suicide in this day and age.
Evaluating the paleoclimatic significance of clay mineral records from a late Pleistocene loess-paleosol section of the Ili Basin, Central Asia

Published: October 2017

AbstractIn this study, we present clay mineral records from a late Pleistocene loess-paleosol sequence in the Ili Basin, Central Asia, and assess their significance for paleoclimatic reconstruction. The results show that the clay minerals are mainly illite (average 60%) and chlorite (28%), with minor kaolinite (9%) and smectite (3%). Illite was of detrital origin with no obvious modification to its crystal structure. Increases in illite content in the loess are ascribed to wind intensity rather than pedogenesis. High proportions of illite in the clay fraction, and of muscovite in the bulk samples of the paleosol units, may lead to an overestimation of the weathering intensity. Kaolinite was likely inherited from the sedimentary rocks, while chlorite might have been inherited from both sedimentary and metamorphic rocks. The paleoclimatic signals of kaolinite and chlorite were unclear, due to reworking by both fluvial and eolian systems. Smectite was more likely formed by the transformation of biotite and illite, and its variation in the loess sequence was also controlled by wind intensity; this was largely due to aggregation and is unlikely to reflect moisture changes. Although the interpretation of paleoclimate evolution may contain some uncertainties, clay mineralogy does provide the possibility of tracing dust provenance.

Published: October 2017

SUMMARYMixing species with different tillering peaks may enhance pasture stability, but intercropping may also alter the plants’ tillering patterns. This study aimed to evaluate tillering dynamics in black oat (Avena strigosa Schreb.) and annual ryegrass (Lolium multiflorum Lam.) pastures grown as monocultures or intercropped. Three following treatments are established: black oat and annual ryegrass pastures grown as monocultures and an intercrop composed of these two species. Tillering dynamics were measured for black oat and annual ryegrass populations separately. When intercropped, tiller birth rates of black oat decreased (20.0 vs. 28.9 tillers 100 tillers−1) and those of annual ryegrass increased (30.5 vs. 14.3 tillers 100 tillers−1), compared to their monocultures. Tiller death rates for annual ryegrass did not differ between monoculture and intercropping (23.9 tillers 100 tillers−1), but black oat presented higher mortality in monocultures (48.8 vs. 36.4 tillers 100 tillers−1). The black oat monoculture had the lowest population stability index (0.80), whereas annual ryegrass in monoculture and intercropped pastures exhibited greater values (on average, 0.92). Our results indicated that black oat and annual ryegrass present distinct tillering dynamics whether grown as monoculture or intercropped, and suggest that intercropping species with elevated death rates (black oat) with later species (annual ryegrass) could be an important tool for maintaining pasture stability throughout the growing season.
ARTHROSCOPIC SURGERY FOR KNEE OSTEOARTHRITIS: IMPACT OF HEALTH TECHNOLOGY ASSESSMENT IN GERMANY
Authors: Fujita-Rohwerder Naomi , Rüther Alric , Sauerland Stefan 
Published: October 2017

Objectives: This study aims to describe how a negative reimbursement decision—based on the health technology assessment (HTA) report of a nondrug intervention—affects healthcare providers in Germany.Methods: Knee arthroscopy was chosen as an example, because as of April 2016 this procedure is no longer reimbursed for osteoarthritis, but is still covered for other indications, including meniscal lesions. The exclusion followed an HTA report prepared by the Institute for Quality and Efficiency in Health Care (IQWiG). Here, we examine how the decision to revoke reimbursement for arthroscopy was perceived by the surgical community. Information was collected from official hospital statistics, the internet, and informal interviews with orthopedic surgeons.Results: In 2015, a total of 37,920 arthroscopic procedures were performed for knee osteoarthritis in Germany. Several surgical societies were unhappy with the negative decision, which was issued as a directive in November 2015, and they challenged the decision-making process as well as the underlying scientific evidence. In March 2016, fifteen societies issued joint recommendations on how to differentiate osteoarthritis from other knee diseases and how to document other diseases in a way that inspections by representatives of health insurance funds would not detect any deficiencies. In informal interviews, orthopedic surgeons indicated that miscoding of the principal diagnosis (meniscal tear rather than knee osteoarthritis) is to be expected, especially in the hospital sector.Conclusions: HTA can have a significant impact on the provision of health services, but various loopholes allow physicians to undermine policy decisions. Therefore, it is important to involve all stakeholders in HTA and to convince them of the benefits of evidence-based medicine.
Buying for Britain, China, or India? Patriotic trade, ethnicity, and market in the 1930s British empire/Commonwealth
Authors: Thackeray David 
Published: October 2017

AbstractThis article seeks to gain a clearer understanding of the language, reach, and limits of competing patriotic trade campaigns in the British empire during the 1930s, focusing on efforts to promote the purchase of Indian, Chinese, and ‘British’ products (a term which was used to refer to goods from both the UK and the Dominions). Civil society groups used patriotic-buying campaigns to promote and maintain forms of regionalized integration in response to the partial deglobalization of trade. Supporters of such campaigns sought to develop trade networks based on ethnic ties which could connect across and, in the Chinese case, beyond imperial spaces. However, the hybridity of colonial subjects’ identities impeded each of these efforts to develop patriotic trade networks and meant that the content, character, and popular appeal of trade campaigns shifted between different regions.
Development of a Shortened Version of the Latent and Manifest	Benefits of Work (LAMB) Scale

Published: October 2017

Abstract. Paid work offers latent benefits (e.g., social contact, time structure) that go beyond mere access to financial resources in predicting individuals’ psychological well-being. Despite the importance of the concept for organizational research and practice, available instruments measuring these latent benefits suffer either from psychometric deficiencies or from a scale length that makes integrating them into large-scale work/life surveys cumbersome. Thus, the current two studies ( N = 1,054 and N = 677) report on the development of the Short Latent and Manifest Benefits of Work scale (LAMB-S; cf. Muller, Creed, Waters, & Machin, 2005 ). The new 18-item instrument showed a clear factor structure, appropriate external validities, and even slight improvements in content and criterion validity for some subscales. Overall, the LAMB-S represents an economical instrument with satisfactory psychometric properties, making it an attractive alternative in situations where participant time is limited.
Predicting Cyberbullying Behavior From Attitudes

Published: October 2017

Abstract. There is a paucity of research testing (a) the longitudinal stability in positive cyberbullying attitudes, (b) whether any change in positive cyberbullying attitudes over time predict subsequent cyberbullying perpetration, and (c) the cross-lagged relations between positive attitudes toward cyberbullying attitudes and behavior over time. The current study focused on empirically testing these theoretical gaps and sampled over 3,000 Singaporean youth participants (at Wave 1) who completed measures of cyberbullying behavior and positive attitudes consecutively for 3 years. Correlations and path analyses showed modest stability in positive cyberbullying attitudes and perpetration over time. Also, latent class analysis classified participants into either stable high attitudes, stable low attitudes, increasing attitudes, or decreasing attitudes. Results using this classification showed that changes in positive cyberbullying attitudes across Waves 1 and 2 predicted Wave 3 cyberbullying, such that those who endorsed cyberbullying attitudes were more likely to cyberbully than those who did not advocate such attitudes. Finally, path analysis results showed significant longitudinal cross-lags between positive attitudes toward cyberbullying and behaviors.

Published: October 2017

AbstractAs a kind of special beams, Bessel beams are always a research hot spot in optics due to its non-diffractive and self-healing properties. Here, zero-order terahertz (THz) Bessel beams with linear and circular polarizations are generated by using a THz quarter wave plate and Teflon axicons with different opening angles. By applying a THz digital holographic imaging system, the evolutions of the transverse (E
x
, E
y
) and longitudinal (E
z
) electric fields are coherently measured and analyzed during the propagation processes of the THz Bessel beams. The vectorial Rayleigh diffraction integral is used to accurately reproduce the amplitude, phase, and non-diffractive feature of each polarization component for the THz Bessel beams. With varying opening angles of the axicons, the focal spots, diffraction-free ranges, and Gouy phase shifts of the THz Bessel beams are compared and discussed. The experiment and simulation results provide a comprehensive view for exactly understanding peculiar features of THz Bessel beams.

Published: October 2017

AbstractX-ray computed tomography (CT) has been widely used to provide patient-specific anatomical information in the forms of tissue attenuation. However, the cumulative radiation induced in CT scan has raised extensive concerns in recently years. How to maintain reconstruction image quality is a major challenge for low-dose CT (LDCT) imaging. Generally, LDCT imaging can be greatly improved by incorporating prior knowledge in some specific forms. A joint estimation framework termed discriminative prior-prior image constrained compressed sensing (DP-PICCS) reconstruction is proposed in this paper. This DP-PICCS algorithm utilizes discriminative prior knowledge via two feature dictionary constraints which built on atoms from the samples of tissue attenuation feature patches and noise-artifacts residual feature patches, respectively. Also, the prior image construction relies on a discriminative feature representation (DFR) processing by two feature dictionary. Its comparison to other competing methods through experiments on low-dose projections acquired from torso phantom simulation study and clinical abdomen study demonstrated that the DP-PICCS method achieved promising improvement in terms of the effectively-suppressed noise and the well-retained structures.
Affecting long-term fear memory formation through optical control of Rac1 GTPase and PAK activity in lateral amygdala
Authors: Das Aniruddha , Dines Monica , Alapin Jessica M. , Lamprecht Raphael 
Published: October 2017

AbstractFear conditioning, a behavioral model for studying fear-related disorders, is believed to be formed by alterations of synaptic efficacy mediated by changes in synaptic transmission and neuronal morphology in lateral amygdala (LA). Rac GTPase and its downstream effector p21-activated kinase (PAK) are involved in such key neuronal functions. Here we show that optical activation of Rac1 GTPase using photoactivatable form of Rac1 (PA-Rac1) in amygdala led to phosphorylation of PAK and inhibition of long-term but not short-term auditory fear conditioning memory formation. Activation of PA-Rac1 in LA one day after fear conditioning had no effect on long-term fear memory tested 24 hrs after PA-Rac1 activation. Inhibition of PAK in LA by microinjection of the PAK inhibitor IPA-3 30 minutes before fear conditioning enhanced long-term but not short-term fear memory formation. Our results demonstrate that photoactivation of Rac1 GTPase in lateral amygdala impairs fear memory formation. Moreover, Rac1 effector PAK activity during fear conditioning constrains the formation of fear memory in LA. Thus, Rac GTPase and PAK proteins may serve as targets for treatment of fear and anxiety disorders.

AbstractThe water quality of the Antas reservoir, under the influence of treated effluents from a uranium mining area Ore Treatment Unit (UTM) with acid mine drainage, was investigated. Samples were collected every 3 months from the Antas reservoir (CAB, P41-E and P14) and from the UTM (P41-S). Chemical and acute 48 h toxicity tests using Ceriodaphnia silvestrii and Daphnia magna analyses were carried out to determine the potential environmental risks due to discharging the uranium mine effluents into this reservoir. All the water samples taken from the treated effluent (P41-S) were positively correlated with elevated concentrations of uranium, manganese, aluminum, zinc and fluoride and with high electrical conductivity and pH values, being considered toxic. In November 2014 water samples taken from the reservoir showed chemical concentrations above the legislation limits for fluoride (4.5 mg L−1) uranium (0.082 mg L−1), sulfate (662.4 mg L−1), manganese (1.125 mg L−1) and aluminum (1.55 mg L−1), and in July 2015 for fluoride (2.55 mg L−1), uranium (0.01 mg L−1) and manganese (0.36 mg L−1). The extremely high average value for hardness (543.55 mg L−1) possibly reduced the toxicity potential of this chemical species mixture with respect to the bioindicators. The influence of the variation in water hardness on the toxicity of the cladocerans was discussed.
