Dealing with post-traumatic stress disorder: The psychological sequelae of bloody Sunday and the response of state services

Objective: This article describes the political context of health and social care services in Northern Ireland at a the of intense social conflict. Method: Concepts from post-traumatic stress disorder (PTSD) and other relevant international psychological literature are then used to study the experience of the Bloody Sunday families, victims of a traumatic event that happened in Derry in January 1972. Results: High levels of psychological morbidity within this population are reported, alongside some evidence that families had not received services that may have helped resolve the trauma. Conclusions: The authors noted that new services planned as a result of the current peace process may offer social workers and other professionals new ways to address the unmet needs of people traumatized by the Troubles.

Psychological determinants of consumer acceptance of personalised nutrition in 9 European countries

OBJECTIVE: To develop a model of the psychological factors which predict people's intention to adopt personalised nutrition. Potential determinants of adoption included perceived risk and benefit, perceived self-efficacy, internal locus of control and health commitment.

METHODS: A questionnaire, developed from exploratory study data and the existing theoretical literature, and including validated psychological scales was administered to N=9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway).

RESULTS: Structural equation modelling indicated that the greater participants' perceived benefits to be associated with personalised nutrition, the more positive their attitudes were towards personalised nutrition, and the greater their intention to adopt it. Higher levels of nutrition self-efficacy were related to more positive attitudes towards, and a greater expressed intention to adopt, personalised nutrition. Other constructs positively impacting attitudes towards personalised nutrition included more positive perceptions of the efficacy of regulatory control to protect consumers (e.g. in relation to personal data protection), higher self-reported internal health locus of control, and health commitment. Although higher perceived risk had a negative relationship with attitude and an inverse relationship with perceived benefit, its effects on attitude and intention to adopt personalised nutrition was less influential than perceived benefit. The model was stable across the different European countries, suggesting that psychological factors determining adoption of personalised nutrition have generic applicability across different European countries.

CONCLUSION: The results suggest that transparent provision of information about potential benefits, and protection of consumers' personal data is important for adoption, delivery of public health benefits, and commercialisation of personalised nutrition.

A Psychological Exploration of Long-Term LSD Users

All research involving the psychoactive compound lysergic acid diethylamide (LSD) was terminated globally following its prohibition more than 50 years ago, though illicit use remained fairly stable. A considerable resurgence of research interest in LSD has received considerable attention in various publications and professional fora. One of the main applications considered is LSD-assisted psychotherapy to address a number of difficulties like end-of-life anxiety, addiction/alcoholism, post-traumatic stress, and depression. However, due to the highly contradictory nature of early research findings and division in the literature, one is left uncertain as to whether psychology as a profession is currently equipped to critically evaluate these advances, let alone embrace them. The purpose of the present study was to contribute to current psychological knowledge on long-term LSD use. A group of long-term LSD users who claimed beneficial use were the focus here. A mixed methods design was employed. 110 users completed an online survey assessing for demographics, patterns of use, and specific personality traits through three psychometric measures, Big Five Inventory (BFI), General Self Efficacy scale (GSE) and Satisfaction With Life Scale (SWLS). Eight individual interviews were also conducted and analysed by Thematic Analysis (TA). Gaining different perspectives on reality and increasing self- awareness appeared to be essential elements of the belief system that these non-problematic long-term LSD users adopted in order to make sense of their LSD use. Qualitative findings also suggested the existence of a common set of life values, rules and the adoption of a hierarchical system between LSD users. Novices appeared to be tutored and guided by elders whose presence and input was valued and who were listened to and respected. A role for ‘wiser/elder’ users as those imparting valuable knowledge to novices was therefore also suggested. The underlying aim may possibly be an attempt to minimise risks and maximise potential benefits of LSD use. A prospective role for LSD as a deterrent of substance misuse, a ‘gateway drug to no drugs’ was also hinted and remains in need of iv further investigation. Claims regarding beneficial LSD use and ‘change’ through LSD use were confirmed by the participant sample. No noteworthy differences between psychometric scores of the LSD-using group and those of the general population (as suggested by normative data comparisons) were found, possibly due to methodological limitations, especially considering the highly subjective nature of the LSD experience and its effects. The determining role of extra-pharmacological variables or ‘set and setting’ in the outcome of LSD use suggested in earlier literature was re-validated. Knowledge on their specific components was enriched, and a potentially significant value for adopting a flexible, adaptable and solution-focused mind-set in order to better manage the effects of LSD was highlighted. Due to the highly selected nature of the participant sample, present findings should serve as suggestions for further research in order to clarify the aforementioned issues and to make explicit the mechanisms by which they operate. The complex nature of LSD, its use and its effects have been re-confirmed here. It is imperative that the current knowledge base on the substance is enriched before LSD is introduced in a clinical psychology professional context.

A definition of literary literacy: a content analysis of literature syllabuses and interviews with Portuguese lecturers of literature

The aim of this paper is to present a definition of literary literacy in the context of majors in languages, literatures and cultures, in Portugal. A definition of literary literacy was deduced from a content analysis of primary data sources and from the theoretical underpinnings of the transactional theory of reading. The primary data sources are fourteen Portuguese and English literature syllabuses from four Portuguese universities (Lisboa, Nova, Coimbra and Porto) and twelve interviews with Portuguese university lecturers of literature. Based on the findings of a content analysis of both syllabuses and interviews, from the lecturers‘ point of view, a literary literate student doing a major in languages, literatures and cultures must, above all, be able to contextualize literary texts and their authors both historically and culturally, must be able to present an interpretation as a coherent text, and must be able to do and organize bibliographical research.

The interpretation of music videos : an interactive relationship between medium and viewer

There is a great deal of evidence to support the examination of an interactive relationship between the medium and the viewer in the interpretation of mainstream media. The exact nature of this relationship, however, is not well understood. The current study was carried out to assess the variables that may help explain why certain people interpret media, such as music videos, differently than others. Jensen's concept of reception analysis describes the relationship between the medium and the audience, and thus remains a strong focus within this study. Differences in the interpretation of music videos were investigated as a function of Absorption, gender role, screen size, age and viewing experience. Multiple regression analyses uncovered independent predictions of sexuality and violence scores by absorption and experience, as well as an interaction between absorption and screen size in the sexuality rating of the music videos.

From cognition to action : a psychological investigation of action regulation in complex and uncertain social systems

Cette thèse présente une revue des réflexions récentes et plus traditionnelles provenant de la théorie des systèmes, de la créativité en emploi, des théories d’organisation du travail et de la motivation afin de proposer une perspective psychologique de la régulation des actions des individus au sein d’environnements de travail complexes et incertains. Des composantes de la Théorie de la Régulation de l’Action (Frese & Zapf, 1994) ainsi que de la Théorie de l’Auto-Détermination (Deci & Ryan, 2000) sont mises en relation afin d’évaluer un modèle définissant certains schémas cognitifs clés associés aux tâches individuelles et collectives en emploi. Nous proposons que ces schémas cognitifs, organisés de manière hiérarchique, jouent un rôle central dans la régulation d’une action efficace au sein d’un système social adaptatif. Nos mesures de ces schémas cognitifs sont basées sur des échelles de mesure proposées dans le cadre des recherches sur l’ambiguïté de rôle (eg. Sawyer, 1992; Breaugh & Colihan, 1994) et sont mis en relation avec des mesures de satisfaction des besoins psychologiques (Van den Broeck, Vansteenkiste, De Witte, Soenens & Lens, 2009) et du bien-être psychologique (Goldberg, 1972). Des données provenant de 153 employés à temps plein d’une compagnie de jeu vidéo ont été récoltées à travers deux temps de mesure. Les résultats révèlent que différents types de schémas cognitifs associés aux tâches individuelles et collectives sont liés à la satisfaction de différents types de besoin psychologiques et que ces derniers sont eux-mêmes liés au bien-être psychologique. Les résultats supportent également l’hypothèse d’une organisation hiérarchique des schémas cognitifs sur la base de leur niveau d’abstraction et de leur proximité avec l’exécution concrète de l’action. Ces résultats permettent de fournir une explication initiale au processus par lequel les différents types de schémas cognitifs développés en emplois et influencé par l’environnement de travail sont associés à l’attitude des employés et à leur bien-être psychologique. Les implications pratiques et théoriques pour la motivation, l’apprentissage, l’habilitation, le bien-être psychologique et l’organisation du travail dans les environnements de travail complexes et incertains sont discutés.

Interpretation of the centromere epigenetic mark to maintain genome stability

Le centromère est la région chromosomique où le kinétochore s'assemble en mitose. Contrairement à certaines caractéristiques géniques, la séquence centromérique n'est ni conservée entre les espèces ni suffisante à la fonction centromérique. Il est donc bien accepté dans la littérature que le centromère est régulé épigénétiquement par une variante de l'histone H3, CENP-A. KNL-2, aussi connu sous le nom de M18BP1, ainsi que ces partenaires Mis18α et Mis18β sont des protéines essentielles pour l'incorporation de CENP-A nouvellement synthétisé aux centromères. Des évidences expérimentales démontrent que KNL-2, ayant un domaine de liaison à l'ADN nommé Myb, est la protéine la plus en amont pour l'incorporation de CENP-A aux centromères en phase G1. Par contre, sa fonction dans le processus d'incorporation de CENP-A aux centromères n'est pas bien comprise et ces partenaires de liaison ne sont pas tous connus. De nouveaux partenaires de liaison de KNL-2 ont été identifiés par des expériences d'immunoprécipitation suivies d'une analyse en spectrométrie de masse. Un rôle dans l'incorporation de CENP-A nouvellement synthétisé aux centromères a été attribué à MgcRacGAP, une des 60 protéines identifiées par l'essai. MgcRacGAP ainsi que les protéines ECT-2 (GEF) et la petite GTPase Cdc42 ont été démontrées comme étant requises pour la stabilité de CENP-A incorporé aux centromères. Ces différentes observations ont mené à l'identification d'une troisième étape au niveau moléculaire pour l'incorporation de CENP-A nouvellement synthétisé en phase G1, celle de la stabilité de CENP-A nouvellement incorporé aux centromères. Cette étape est importante pour le maintien de l'identité centromérique à chaque division cellulaire. Pour caractériser la fonction de KNL-2 lors de l'incorporation de CENP-A nouvellement synthétisé aux centromères, une technique de microscopie à haute résolution couplée à une quantification d'image a été utilisée. Les résultats générés démontrent que le recrutement de KNL-2 au centromère est rapide, environ 5 minutes après la sortie de la mitose. De plus, la structure du domaine Myb de KNL-2 provenant du nématode C. elegans a été résolue par RMN et celle-ci démontre un motif hélice-tour-hélice, une structure connue pour les domaines de liaison à l'ADN de la famille Myb. De plus, les domaines humain (HsMyb) et C. elegans (CeMyb) Myb lient l'ADN in vitro, mais aucune séquence n'est reconnue spécifiquement par ces domaines. Cependant, il a été possible de démontrer que ces deux domaines lient préférentiellement la chromatine CENP-A-YFP comparativement à la chromatine H2B-GFP par un essai modifié de SIMPull sous le microscope TIRF. Donc, le domaine Myb de KNL-2 est suffisant pour reconnaître de façon spécifique la chromatine centromérique. Finalement, l'élément reconnu par les domaines Myb in vitro a potentiellement été identifié. En effet, il a été démontré que les domaines HsMyb et CeMyb lient l'ADN simple brin in vitro. De plus, les domaines HsMyb et CeMyb ne colocalisent pas avec CENP-A lorsqu'exprimés dans les cellules HeLa, mais plutôt avec les corps nucléaires PML, des structures nucléaires composées d'ARN. Donc, en liant potentiellement les transcrits centromériques, les domaines Myb de KNL-2 pourraient spécifier l'incorporation de CENP-A nouvellement synthétisé uniquement aux régions centromériques.

Design of Gaussian basis sets to the theoretical interpretation of IR-spectrum of hexaaquachromium (III) ion, tetraoxochromium (IV) ion, and tetraoxochromium (VI) ion

The Generator Coordinate Hartree-Fock (GCHF) method is employed to design 16s, 16s10p, 24s17p13d, 25s17p13d, and 26s17p Gaussian basis sets for the H ((2)S), O ((3)P), O(2-) ((1)S), Cr(3+) ((4)F), Cr(4+) ((3)F), and Cr(6+) ((1)S) atomic species. These basis sets are then contracted to (4s) for H ((2)S), (6s4p) for O ((3)P), and O(2-) ((1)S), (986p3d) for Cr(3+) ((4)F), (10s8p3d) for Cr(4+) ((3)F), and (13s7p) for Cr(6+) (1S) by a standard procedure. For evaluation of the quality of those basis sets in molecular calculations, we have accomplished studies of total and orbital (HOMO and HOMO-1) energies at the HF-Roothaan level for the molecular species of our interest. The results obtained with the contracted basis sets are compared to the values obtained with our extended basis sets and to the standard 6-311G basis set from literature. Finally, the contracted basis sets are enriched with polarization function and then utilized in the theoretical interpretation of IR-spectrum of hexaaquachromium (III) ion, [Cr(H(2)O)(6)](3+), tetraoxochromium (IV) ion, [CrO(4)](4-), and tetraoxochromium (VI) ion, [CrO(4)](2-). The respective theoretical harmonic frequencies and IR-intensities were computed at the density functional theory (DFT) level. In the DFT calculations we employed the Becke's 1988 functional using the LYP correlation functional. The comparison between the results obtained and the corresponding experimental values indicates a very good description of the IR-spectra of the molecular ions studied, and that the GCHF method is still a legitimate alternative for selection of Gaussian basis sets.

Overview of literature and information on "khat-related" mortality: a call for recognition of the issue and further research

During the past 20 years or so, more has become known about the properties of khat, its pharmacology, physiological and psychological effects on humans. However, at the same time its reputation of social and recreational use in traditional contexts has hindered the dissemination of knowledge about its detrimental effects in terms of mortality. This paper focuses on this particular deficit and adds to the knowledge-base by reviewing the scant literature that does exist on mortality associated with the trade and use of khat. We sought all peer-reviewed papers relating to deaths associated with khat. From an initial list of 111, we identified 15 items meeting our selection criteria. Examination of these revealed 61 further relevant items. These were supplemented with published reports, newspaper and other media reports. A conceptual framework was then developed for classifying mortality associated with each stage of the plant's journey from its cultivation, transportation, consumption, to its effects on the human body. The model is demonstrated with concrete examples drawn from the above sources. These highlight a number of issues for which more substantive statistical data are needed, including population-based studies of the physiological and psychological determinants of khat-related fatalities. Khat-consuming communities, and health professionals charged with their care should be more aware of the physiological and psychological effects of khat, together with the risks for morbidity and mortality associated with its use. There is also a need for information to be collected at international and national levels on other causes of death associated with khat cultivation, transportation, and trade. Both these dimensions need to be understood.

Psychological Sense of Community: A New Construct for the Field of Management

This article introduces a new construct to the field of management called Psychological Sense of Community (PSOC). This is important because management scholars are calling for the creation of communities in organizations in an environment that lacks appropriate construct development. The aims of this article are threefold: (a) develop a working definition of PSOC via a review of the extant literature on PSOC from other disciplines with the goal of translating it into the domain of management, (b) synthesize findings from parallel literatures on the outcomes of PSOC with an eye toward exploring the relevance of such outcomes in management contexts, and (c) assess the value of PSOC as it relates to its uniqueness in relation to other prominent management constructs and its scope of applicability in a variety of management inquiry areas.

Endovascular treatment for acute ischemic stroke patients: implications and interpretation of IMS III, MR RESCUE, and SYNTHESIS EXPANSION trials: A report from the Working Group of International Congress of Interventional Neurology

OBJECTIVE The results of Interventional Management of Stroke (IMS) III, Magnetic Resonance and REcanalization of Stroke Clots Using Embolectomy (MR RESCUE), and SYNTHESIS EXPANSION trials are expected to affect the practice of endovascular treatment for acute ischemic stroke. The purpose of this report is to review the components of the designs and methods of these trials and to describe the influence of those components on the interpretation of trial results. METHODS A critical review of trial design and conduct of IMS III, MR RESCUE, and SYNTHESIS EXPANSION is performed with emphasis on patient selection, shortcomings in procedural aspects, and methodology of data ascertainment and analysis. The influence of each component is estimated based on published literature including multicenter clinical trials reporting on endovascular treatment for acute ischemic stroke and myocardial infarction. RESULTS We critically examined the time interval between symptom onset and treatment and rates of angiographic recanalization to differentiate between "endovascular treatment" and "parameter optimized endovascular treatment" as it relates to the IMS III, MR RESCUE, and SYNTHESIS EXPANSION trials. All the three trials failed to effectively test "parameter optimized endovascular treatment" due to the delay between symptom onset and treatment and less than optimal rates of recanalization. In all the three trials, the magnitude of benefit with endovascular treatment required to reject the null hypothesis was larger than could be expected based on previous studies. The IMS III and SYNTHESIS EXPANSION trials demonstrated that rates of symptomatic intracerebral hemorrhages subsequent to treatment are similar between IV thrombolytics and endovascular treatment in matched acute ischemic stroke patients. The trials also indirectly validated the superiority/equivalence of IV thrombolytics (compared with endovascular treatment) in patients with minor neurological deficits and those without large vessel occlusion on computed tomographic/magnetic resonance angiography. CONCLUSIONS The results do not support a large magnitude benefit of endovascular treatment in subjects randomized in all the three trials. The possibility that benefits of a smaller magnitude exist in certain patient populations cannot be excluded. Large magnitude benefits can be expected with implementation of "parameter optimized endovascular treatment" in patients with ischemic stroke who are candidates for IV thrombolytics.

Characterization of OSIRIS NAC filters for the interpretation of multispectral data of comet 67P/Churyumov-Gerasimenko

Context. We interpret multicolor data from OSIRIS NAC for the remote-sensing exploration of comet 67P/Churyumov-Gerasimenko. Aims. We determine the most meaningful definition of color maps for the characterization of surface variegation with filters available on OSIRIS NAC. Methods. We analyzed laboratory spectra of selected minerals and olivine-pyroxene mixtures seen through OSIRIS NAC filters, with spectral methods existing in the literature: reflectance ratios, minimum band wavelength, spectral slopes, band tilt, band curvature, and visible tilt. Results. We emphasize the importance of reflectance ratios and particularly the relation of visible tilt vs. band tilt. This technique provides a reliable diagnostic of the presence of silicates. Color maps constructed by red-green-blue colors defined with the green, orange, red, IR, and Fe2O3 filters let us define regions that may significantly differ in composition.

Psychological Ownership of Employees as a Mediator in the Justice - Affective Commitment Relationship

Numerous scholars have accumulated evidence on the positive effects that employees’ organizational justice perceptions exert on work-related outcomes such as affective commitment. However, research still lacks understanding of the underlying mechanisms connecting the two constructs. In this article we aim to narrow this gap by examining the concept of psychological ownership as a possible mediator between organizational justice perceptions and affective commitment. Investigating a sample of 619 employees, we find distributive justice to be positively related to psychological ownership, and observe psychological ownership as a full mediator of the distributive justice and affective commitment relationship. These insights offer a new explanation in understanding the justice-commitment connection, contributing to both organizational justice and psychological ownership literature and opening up ways for promising future research.
