Personality and emotional processing: A relationship between extraversion and the late positive potential in adolescence

Published: April 2015

AbstractNeuroticism and extraversion are multifaceted affective‐laden personality traits that have been associated with major depressive disorder (MDD). Research and theory have argued that extraversion, and particularly its facet positive emotionality, is specific to MDD, while neuroticism is common across internalizing disorders. Converging evidence has suggested that MDD is associated with reduced engagement with emotional stimuli, but it remains unclear whether either extraversion, neuroticism, or both modulate reactivity to emotional cues. The late positive potential (LPP) is an event‐related brain potential that is uniquely suited to assess engagement with emotional stimuli because it reflects sustained attention toward emotional content. The current study examined the LPP in relation to personality traits that may confer risk for depression by examining the relationship between the LPP and both neuroticism and extraversion in never‐depressed adolescent girls. Specifically, 550 girls aged 13.5–15.5 with no lifetime history of depression completed an emotional picture‐viewing task, and the LPP was measured in response to neutral, pleasant, and unpleasant pictures. Personality traits were gathered via self‐ and informant report. Results indicated that high extraversion was associated with a potentiated LPP to emotional pictures—and this effect was accounted for by positive emotionality in particular. In contrast, there was no association between the LPP and neuroticism or its facets. The present study is one of the first to demonstrate that extraversion is associated with variation in neural indices of emotional picture processing, similar to what has been observed among individuals with depression and at high risk for depression.

Published: April 2015

AbstractIn aquaculture hatcheries, egg disinfection is commonly employed as a mortality mitigation and disease management tool. In addition, disinfection protocols are utilized in research facilities, as a means to create axenic and gnotobiotic larval models. For the latter, a complete sterilization of the eggs is warranted. Multiple research groups have tested various disinfectants in fish eggs adopting different protocols and a range of parameters to evaluate their efficacy and safety. However, there is a clear lack of a critical review listing these different studies and stressing the advantages and shortcomings of the protocols and adopted disinfectants. This review provides a commented survey of the findings/experiments on the most frequently used and upcoming disinfecting products, the protocols in which they are included and their purposes with emphasis on decreasing bacterial and/or fungal load, underscoring the benefits and the limitations of each product. Supplemented with a critical note, this review assists both aquaculturists and researchers in making an informed choice. Moreover, it will help stakeholders to identify the gaps in knowledge where future research on egg disinfection is needed.
Bootstrapping the Portmanteau Tests in Weak Auto-Regressive Moving Average Models
Authors: Zhu Ke 
Published: April 2015

SummaryThe paper uses a random-weighting (RW) method to bootstrap the critical values for the Ljung–Box or Monti portmanteau tests and weighted Ljung–Box or Monti portmanteau tests in weak auto-regressive moving average models. Unlike the existing methods, no user-chosen parameter is needed to implement the RW method. As an application, these four tests are used to check the model adequacy in power generalized auto-regressive conditional heteroscedasticity models. Simulation evidence indicates that the weighted portmanteau tests have a power advantage over other existing tests. A real example on the Standard and Poor's 500 index illustrates the merits of our testing procedure. As an extension, the blockwise RW method is also studied.
Using Post-Outcome Measurement Information in Censoring-by-Death Problems
Authors: Yang Fan , Small Dylan S. 
Published: April 2015

Summary
Many clinical studies on non-mortality outcomes such as quality of life suffer from the problem that the non-mortality outcome can be censored by death, i.e. the non-mortality outcome cannot be measured if the subject dies before the time of measurement. To address the problem that this censoring by death is informative, it is of interest to consider the average effect of the treatment on the non-mortality outcome among subjects whose measurement would not be censored under either treatment or control, which is called the survivor average causal effect (SACE). The SACE is not point identified under usual assumptions but bounds can be constructed. The previous literature on bounding the SACE uses only the survival information before the measurement of the non-mortality outcome. However, survival information after the measurement of the non-mortality outcome could also be informative. For randomized trials, we propose a set of ranked average score assumptions that make use of survival information before and after the measurement of the non-mortality outcome which are plausibly satisfied in many studies and we develop a two-step linear programming approach to obtain the closed form for bounds on the SACE under our assumptions. We also extend our method to randomized trials with non-compliance or observational studies with a valid instrumental variable to obtain bounds on the complier SACE which is presented in on-line supplementary material. We apply our method to a randomized trial of the effect of mechanical ventilation with lower tidal volume versus traditional tidal volume for acute lung injury patients. Our bounds on the SACE are much shorter than the bounds that are obtained by using only the survival information before the measurement of the non-mortality outcome.
AnM-Estimator of Spatial Tail Dependence
Authors: Einmahl John H. J. , Kiriliouk Anna , Krajina Andrea , Segers Johan 
Published: April 2015

SummaryTail dependence models for distributions attracted to a max-stable law are fitted by using observations above a high threshold. To cope with spatial, high dimensional data, a rank-based M-estimator is proposed relying on bivariate margins only. A data-driven weight matrix is used to minimize the asymptotic variance. Empirical process arguments show that the estimator is consistent and asymptotically normal. Its finite sample performance is assessed in simulation experiments involving popular max-stable processes perturbed with additive noise. An analysis of wind speed data from the Netherlands illustrates the method.

Authors: Black Donald W. , Coryell William , Crowe Raymond , McCormick Brett , Shaw Martha , Allen Jeff 
Published: April 2015

We examined the relationship between suicidal ideations and attempts in 95 probands with pathological gambling (PG), 91 controls, and 1075 first‐degree relatives. The results were analyzed using logistic regression with generalized estimating equations. Thirty‐four PG probands (35.8%) and 4 controls (4.4%) had attempted suicide (OR = 12.12, p < .001); in 13 probands, the attempt occurred before PG onset. Lifetime suicidal ideations occurred in 60 PG probands (63.2%) and 12 controls (13.2%) (OR = 11.29, p < .001). Suicidality in PG probands is a marker of PG severity and is associated with greater psychiatric comorbidity. Offspring of PG probands had significantly higher rates of suicide attempts than control offspring.
Dealing with Difference in Desistance Theory: The Promise of Intersectionality for New Avenues of Inquiry
Authors: Fader Jamie J. , Traylor LaTosha L. 
Published: April 2015

AbstractThe last two decades have witnessed a rapid growth in research and theorizing about the desistance process, namely the causal mechanisms behind the termination or slowing of offending that frequently accompany adulthood. This flurry of scholarly activity has been spurred by both the ascendance of the life course paradigm of criminology, which examines patterns of criminal offending over the life span, but also by the very real practical demands of supporting the transitions of over 700,000 former prisoners released to their communities each year.The field of desistance theory has expanded upon its original formulations that were largely (although not exclusively) based on White males and has recently turned to examining (1) the potential invariance of desistance processes for members of other groups and (2) the unique experiences of reentry and pathways to desistance for sub‐groups. In this essay, we review these recent developments, particularly as they relate to women, persons of color, and incarcerated youth. Finally, we turn to the intersectionality framework, which examines the social location of individuals within interlocking systems of oppression (e.g., race, class, gender, age, sexual orientation, and ability, among others). We conclude with some suggestions for how intersectionality could be used to expand the conceptual and practical boundaries of research on desistance and reentry.
Girls Just Want to Have Fun (Too): Complicating the Study of Femininity and Women's Leisure
Authors: Stalp Marybeth C. 
Published: April 2015

AbstractSociology is the study of society. However, not all aspects of society get the same scholarly attention by academics. Throughout my research program, I have highlighted some of the lesser‐covered areas of society, like feminine leisure seen in activities such as quilting, knitting, and membership in the Red Hat Society. In this article, I discuss how the development of sociology as a discipline has focused on public matters in society like the economy, leaving non‐economic or private activities with less attention. My research on women's feminine leisure from a third‐wave feminism perspective importantly addresses a gap in the discipline.

Published: April 2015

AbstractHow people come to develop a feeling of belongingness to a new social group and orchestrate this new group membership with pre‐existing identities within the self‐concept is a theoretically and socially relevant phenomenon that has received increased scientific attention in recent years. Models from different fields of psychology – including social, cultural, and organizational psychology – have proposed factors involved in this change and integration process along with consequences of this phenomenon. We present overview of this literature, including a recent model on the process of identity integration: the cognitive‐developmental model of social identity integration. Specifically, this model highlights the fundamental cognitive and developmental processes involved as people develop new social identifications and integrate their different identities into their overall self‐concept. We then present recent empirical evidence testing the model. Finally, we propose conceptual, methodological, and statistical avenues for future research on identity change and integration.
Pulmonary mycobacterial spindle cell pseudotumor in a lung transplant patient: progression without therapy and response to therapy
Authors: Franco M. , Amoroso A. , Burke A.P. , Britt E.J. , Reed R.M. 
Published: April 2015

AbstractMycobacterial spindle cell pseudotumor (MSP) represents a rare, non‐malignant, mass‐forming reaction to various mycobacterial infections, typically occurring in immunocompromised patients. It is characterized by the proliferation of spindle‐shaped fibrohistiocytic cells without the formation of epithelioid granulomas. Without staining for acid‐fast bacilli, histological distinction from other spindle cell lesions, including malignancy, can be difficult. Most of the MSP cases reported in the literature have involved lymph nodes, skin, spleen, or bone marrow, but rarely involve the lung. MSP predominately occurs in patients who are immunosuppressed. We present a patient with MSP of the transplanted lung caused by non‐tuberculous mycobacteria, in whom both the natural course of the untreated pseudotumor as well as the response to antimycobacterial treatments were observed.
A land plant‐specific thylakoid membrane protein contributes to photosystem II maintenance in Arabidopsis thaliana
Authors: Liu Jun , Last Robert L. 
Published: April 2015

SummaryThe structure and function of photosystem II (PSII) are highly susceptible to photo‐oxidative damage induced by high‐fluence or fluctuating light. However, many of the mechanistic details of how PSII homeostasis is maintained under photoinhibitory light remain to be determined. We describe an analysis of the Arabidopsis thaliana gene At5g07020, which encodes an unannotated integral thylakoid membrane protein. Loss of the protein causes altered PSII function under high‐irradiance light, and hence it is named ‘Maintenance of PSII under High light 1’ (MPH1). The MPH1 protein co‐purifies with PSII core complexes and co‐immunoprecipitates core proteins. Consistent with a role in PSII structure, PSII complexes (supercomplexes, dimers and monomers) of the mph1 mutant are less stable in plants subjected to photoinhibitory light. Accumulation of PSII core proteins is compromised under these conditions in the presence of translational inhibitors. This is consistent with the hypothesis that the mutant has enhanced PSII protein damage rather than defective repair. These data are consistent with the distribution of the MPH1 protein in grana and stroma thylakoids, and its interaction with PSII core complexes. Taken together, these results strongly suggest a role for MPH1 in the protection and/or stabilization of PSII under high‐light stress in land plants.
Failure of self‐disclosure of deferrable risk behaviors associated with transfusion‐transmissible infections in blood donors
Authors: Wong Horas Tze Hoo , Lee Shui Shan , Lee Cheuk‐Kwong , Chan Denise Pui Chung 
Published: April 2015

BACKGROUNDTo date, most studies on deferral of blood donors have focused on men who have sex with men (MSM) and/or injecting drug users. Few have examined deferrable risk behaviors relating to transfusion‐transmissible infections (TTIs) in general. This study aimed to examine the prevalence of, and factors associated with, nondisclosure of TTI‐related risk behaviors in donors.STUDY DESIGN AND METHODSChinese‐speaking donors who had just given blood in Hong Kong were invited to self‐complete an anonymous questionnaire. Practices of one or more of seven deferrable risk behaviors associated with TTI were inquired. Factors associated with noncompliance with self‐disclosure were evaluated by logistic regression.RESULTSOver a 4‐week study period in 2012, a total of 1143 donors were recruited. Overall, 0.2% gave a history of drug injection, 1.7% had had sex with sex worker(s), and 0.3% had had sex with a human immunodeficiency virus–infected partner, while none had been paid for sex. Some 1.5% of male donors reported having same‐sex behaviors. Factors associated with noncompliance were male gender (odds ratio [OR] 31.1; 95% confidence interval [CI], 3.7‐263.6), having multiple sex partners (OR, 89.7; 95% CI, 28.7‐279.9), and previous history of temporary deferral (OR, 11.4; 95% CI, 2.5‐53.3). If suspected noncompliance was included, the overall prevalence of nondisclosure of deferrable behaviors could be high at 6.5%.CONCLUSIONAlbeit uncommon, some donors fail to provide accurate answers to predonation screening questions and are not deferred appropriately. There is room for improvement to make deferral policy acceptable and understandable, so as to minimize the risk of TTI. Efforts are also needed to tackle the paucity of data on noncompliance of non‐MSM donors.

Within the nematode class Chromadorea, the suborder Tylenchina is an ecologically and morphologically diverse assemblage of nematodes that includes free‐living microbivores, fungivores and various types of plant parasites. A recent nematode classification system based largely on SSU rDNA phylogenetic trees classified suborder Tylenchina to include four infraorders: Panagrolaimomorpha, Cephalobomorpha, Tylenchomorpha and Drilonematomorpha, and phylogenetic relationships among species of these infraorders have not always been robustly supported. In this study, we determined the complete mitochondrial genome sequences of three Tylenchina species (Aphelenchus avenae [Aphelenchidae, Tylenchomorpha], Halicephalobus gingivalis, Panagrellus redivivus [Panagrolaimomorpha]) and the partial genome sequence of Acrobeles complexus (Cephalobomorpha) and used these sequences to infer phylogenetic relationships among representatives of the Tylenchina and other nematodes. Phylogenetic analysis of amino acid sequences for 12 protein‐coding genes of 100 nematode species supports monophyly of: Chromadorea, Spiruromorpha, Oxyuridomorpha, Ascarididae + Toxocaridae + Anisakidae, Meloidogynidae + Pratylenchidae + Heteroderidae and Aphelenchoidea. Bayesian and maximum‐likelihood analyses also show the nested position of Diplogasteromorpha within Rhabditomorpha, and Rhigonematomorpha within Ascaridomorpha. These analyses also show non‐monophyly of: clade III, Ancylostomatidae, Panagrolaimomorpha, Tylenchina and Tylenchomorpha. Reconstructed mitochondrial genome phylogeny also revealed that among two main Tylenchomorpha groups, the monophyletic group representing Aphelenchoidea species was sister to the large clade consisting of Ascaridomorpha, Diplogasteromorpha, Rhabditomorpha and Rhigonematomorpha and some Panagrolaimomorpha species, whereas Tylenchoidea species were sister to the most inclusive assemblage containing all infraordinal groups of Chromadorea, except for P. redivivus (Panagrolaimomorpha) and Acrobeles complexus (Cephalobomorpha). The monophyly of Aphelenchoidea (i.e. sister relationship between Aphelenchidae and Aphelenchoididae) recovered in this study indicates that similarity in certain aspects of pharyngeal structure between these two families appears best explained by common ancestry, rather than convergent evolution.
Increasing the Value of Uncertain Weather and River Forecasts for Emergency Managers
Authors: Hoss Frauke , Fischbeck Paul 
Published: April 2015

Abstract
Emergency managers (EMs) use National Weather Service (NWS) forecasts to prepare for and respond to severe weather events. To effectively facilitate such decision making, the NWS needs to understand this large and important group of clients. EMs translate the forecasts to local topography, suggest actions to take in preparation of high water levels, and use their local network and reputation to make people act. For this study, 17 EMs in towns along rivers were interviewed and asked to describe their use of river and weather forecasts.
Forecast uncertainty is one of the many uncertainties an EM has to manage when coordinating an emergency response. Each of the interviewed EMs who uses river forecasts was acutely aware that river forecasts often have substantial uncertainty. To cope with this uncertainty, EMs engage in extensive information gathering before forming their own judgments. However, EMs often do not communicate their judgment of the situation to the public, fearing potential liability claims and backlash from the media. For emergency management decisions, while EMs do consider forecast data, they rely heavily on recorded data and monitoring crews, limiting the benefits of forecasts that can be made with significant lead time. This paper arrives at recommendations for the NWS on how to increase the value of river and weather forecasts for decision making in emergency management.
Indian Summer Monsoon Rainfall Processes in Climate Change Scenarios
Authors: Asharaf Shakeel , Ahrens Bodo 
Published: April 2015

Abstract
Indian summer monsoon rainfall was examined in two different greenhouse gas emission scenarios: the Special Report on Emissions Scenarios (SRES; B1) and a similar greenhouse gas scenario, the new representative concentration pathways (RCPs; RCP4.5). The rainfall change in the climate model projections through remotely induced changes in precipitation processes and through changes in precipitation efficiency processes was discussed. To that end, two model setups were applied: 1) the regional climate model (RCM) Consortium for Small-Scale Modelling in Climate Mode (COSMO-CLM), nested in the global climate model (GCM) ECHAM5/Max Planck Institute ocean model (ECHAM5/MPIOM), applying the greenhouse gas scenario B1; and 2) the RCM nested in a newer version of the GCM, ECHAM6/MPIOM, incorporating the RCP4.5 scenario. Both GCM simulations showed a slight increase in precipitation over central India toward the end of the twenty-first century. This slight increase was the result of two largely compensating changes: increase of remotely induced precipitation and decrease of precipitation efficiency. The RCM with the scenario RCP4.5 followed this trend, but with smaller changes. However, the RCM with B1 showed a decreasing trend in precipitation because of a slightly larger absolute change of the reduced precipitation efficiency compared to the change caused by the remote processes. Changes of these processes in the scenario simulations were larger than the natural variability, as simulated in an unperturbed preindustrial greenhouse gas control (CTL) climate simulation. Results indicated that the projection of the Indian summer monsoon rainfall is still a key challenge for both the GCM and the RCM.
Climate-Driven Variability in the Southern Ocean Carbonate System
Authors: Conrad Christopher J. , Lovenduski Nicole S. 
Published: April 2015

Abstract
Seasonal and interannual variability in the Southern Ocean carbonate system is investigated using output from a historically forced (1948–2007) ocean general circulation model with embedded biogeochemistry. Atmospheric CO2 is fixed at preindustrial levels to investigate carbonate system variability in the absence of an anthropogenic CO2 perturbation. It is found that nearly a quarter of interannual variability in Southern Ocean Pacific sector surface carbonate ion concentration can be explained by variability in ENSO, with Pacific sector surface decreasing by 0.43 mmol m−3 per standard deviation decrease in the ENSO-3.4 index. ENSO-related variability in vertical advection of dissolved inorganic carbon (DIC) drives this relationship between ENSO and surface . It is also found that positive phases of the southern annular mode (SAM) are associated with decreased Southern Ocean surface , an association driven by SAM-related variability in vertical advection of DIC. Despite the influence of the SAM on interannual variability in surface , only 4.5% of the trend in natural Southern Ocean surface exhibits linear congruence with the trend in wind stress. Given this, the authors predict that the positive trend in the SAM will not have a substantial impact on ocean acidification. Last, ENSO is found to alter the wintertime minimum in surface . Assuming a business-as-usual acidification rate of 0.5 mmol m−3 yr−1, exacerbation of the wintertime minimum during La Niña conditions may advance the date of aragonite undersaturation within the central Pacific sector of the Southern Ocean by as much as 8 yr.
