Development of the Davos Assessment of Cognitive Biases Scale (DACOBS)

Objective: Cognitive problems and biases play an important role in the development and continuation of psychosis. A self-report measure of these deficits and processes was developed (Davos Assessment of Cognitive Biases Scale: DACOBS) and is evaluated in this study. Methods: An item pool made by international experts was used to develop a self-report scale on a sample of 138 schizophrenia spectrum patients. Another sample of 71 patients was recruited to validate the subscales. A group of 186 normal control subjects was recruited to establish norms and examine discriminative validity. Results: Factor analyses resulted in seven factors, each with six items (jumping to conclusions, belief inflexibility bias, attention for threat bias, external attribution bias, social cognition problems, subjective cognitive problems and safety behavior). All factors independently explained the variance (eigenvalues > 2) and total explained variance was 45%. Reliability was good (Cronbach's alpha = .90; split-half reliability = .92; test–retest reliability = .86). The DACOBS discriminates between schizophrenia spectrum patients and normal control subjects. Validity was affirmed for five of seven subscales. The scale ‘Subjective Cognitive problems’ was not associated with objective cognitive functioning and ‘Social cognition problems’ was not associated with the Hinting task, but with the scale measuring ideas of social reference. Conclusions: The DACOBS scale, with seven independent subscales, is reliable and valid for use in clinical practice and research.

Struggling, Coping, And Thriving: Sense-Making In Stepfamily Couples' Narratives About Coparenting

The term coparenting implies a bioparental dyad that often excludes the stepparent's role in sharing parenting across joint-custody households. Focusing solely on this dyad also precludes gaining an understanding of how stepfamily couples manage together the communication and sharing of parental responsibilities with the parent(s) in the shared children's other home. In a departure from this bioparental dyad-focused approach, this study locates the stepfamily couple at the center of an inquiry into managing coparenting across households. This mixed methods design study included in-depth interviews of 32 stepfamily couples whose narratives about coparenting were analyzed using grounded theory methods. Forty-one percent of stepparents engage in direct coparenting communication, sometimes manifested as the coactive approach identified in this study. Stepfamily couples also involve the stepparent indirectly in coparenting communication, through the conferred and consultative approaches. As well, the couples' narratives about coparenting identify them as either united, where they share the experience, or divided, where coparenting is reserved exclusively for the bioparent to manage. The stepfamily couples' narratives about significant coparenting experiences revealed that they experience and make sense of coparenting as 1) struggling, 2) coping, or 3) thriving. No significant relationship was found between marital satisfaction and experiencing coparenting as strugglers, copers or thrivers. Grounded theory analysis of these narratives also reflects the four dichotomous dimensions of 1) regard-disregard, 2) decency-duplicity, 3) facilitation-interference, and 4) accommodation-inflexibility. Significant incidents located along these dimensions contribute to the stepfamily couples' identification as struggling, coping, or thriving in coparenting. Experiences on the extreme ends of the dichotomous dimensions generate positive and negative turning points for the coparenting interactions and relationships. As well, experiences on the negative end of the dimensional poles can present challenges for the stepfamily couples. Finally, a synthesis of the findings related to the dichotomous dimensions generates a theory of shared parenting values expectancy.

Sobre a evasão estudantil na Escola Politécnica da Universidade de São Paulo: identificação e possíveis causas.

A evasão estudantil afeta as universidades, privadas e públicas, no Brasil, trazendo-lhes prejuízos financeiros proporcionais à incidência, respectivamente, de 12% e de 26% no âmbito nacional e de 23% na Universidade de São Paulo (USP), razão pela qual se deve compreender as variáveis que governam o comportamento. Neste contexto, a pesquisa apresenta os prejuízos causados pela evasão e a importância de pesquisá-la na Escola Politécnica da USP (EPUSP): seção 1, desenvolve revisão bibliográfica sobre as causas da evasão (seção 2) e propõe métodos para obter as taxas de evasão a partir dos bancos de dados do Governo Federal e da USP (seção 3). Os resultados estão na seção 4. Para inferir sobre as causas da evasão na EPUSP, analisaram-se bancos de dados que, descritos e tratados na seção 5.1, contêm informações (P. Ex.: tipo de ingresso e egresso, tempo de permanência e histórico escolar) de 16.664 alunos ingressantes entre 1.970 e 2.000, bem como se propuseram modelos estatísticos e se detalharam os conceitos dos testes de hipóteses 2 e t-student (seção 5.2) utilizados na pesquisa. As estatísticas descritivas mostram que a EPUSP sofre 15% de evasão (com maior incidência no 2º ano: 24,65%), que os evadidos permanecem matriculados por 3,8 anos, que a probabilidade de evadir cresce após 6º ano e que as álgebras e os cálculos são disciplinas reprovadoras no 1º ano (seção 5.3). As estatísticas inferenciais demonstraram relação entre a evasão - modo de ingresso na EPUSP e evasão - reprovação nas disciplinas do 1º ano da EPUSP, resultados que, combinados com as estatísticas descritivas, permitiram apontar o déficit vocacional, a falta de persistência, a falta de ambientação à EPUSP e as deficiências na formação predecessora como variáveis responsáveis pela evasão (seção 5.4).

Defence Mechanisms of Infertile Couples vs Fertile Couples

Defence mechanisms (DM) were investigated in infertile couples (n = 60) waiting for their first infertility consultation, making use of the Defense Mechanisms Inventory (DMI). When compared with results of fertile couples (n = 60), infertile men and women showed a significant trend to avoid the use of defence mechanisms that enable the expression of aggressive impulses as well as a tendency to overuse defence mechanisms that enable the rationalization and negation of frustrating sutations. Such data seem to indicate the presence of defensive inflexibility in couples affected by reproductive stress, while in common couples defensive flexibility is to be expected.

Sovereign debt and its restructuring framework in the Euro area. Bruegel Working Paper 2013/05, August 2013

To compensate for the inflexibility of fixed exchange rates, the euro area needs flexibility through a system of orderly debt restructuring. With virtually no room for macroeconomic manoeuvring since the crisis onset, fiscal austerity has been the main instrument for achieving reductions in public debt levels; but because austerity also weakens growth, public debt ratios have barely budged. Austerity has also implied continued high private debt ratios. And these debt burdens have perpetuated economic stasis. Economic theory,history, and the recent experience all call for a principled debt restructuring mechanism as an integral element of the euro area’s design. Sovereign debt should be recognised as equity (a residual claim on the sovereign), operationalised by the automatic lowering of the debt burden upon the breach of contractually-specified thresholds. Making debt more equity-like is also the way forward for speedy private deleveraging. This debt-equity swap principle is a needed shock absorber for the future but will also serve as the principle to deal with the overhang of ‘legacy’ debt.

An investigation into the similarities and differences governing the cryopreservation success of koala (Phascolarctos cinereus: goldfuss) and common wombat (Vombatus ursinus: shaw) spermatozoa

The aim of this study was to determine the relative cryopreservation success of koala and wombat spermatozoa and to investigate reasons for their respective post-thaw survival by examining the sperm's response to a range of osmotic media and determining the presence and distribution of F-actin. An hypothesis was proposed that F-actin may be imparting a degree of structural inflexibility to the koala sperm plasma membrane; hence, exposure of spermatozoa to cytochalasin D (5 mu M), a F-actin depolymerisation agent, should result in increased plasticisation of the membrane and greater tolerance of cell volume changes that typically occur during cryopreservation. In experiment 1, koala (n = 4) and wombat (n = 4) spermatozoa packaged in 0.25 mL straws were cryopreserved using two freezing rates (fast-3 cm above liquid N2 interface; slow-6 degrees C/min in a freezing chamber) and two glycerol concentrations (8 and 14% v/v) in a tris-citrate glucose buffer with 15% (v/v) egg yolk. Wombat spermatozoa showed better (P < 0.01) post-thaw survival (% motile, % intact plasma membranes, % decondensed sperm heads) than koala spermatozoa. When exposed to media of varying osmolality, koala spermatozoa were less tolerant (% intact plasma membrane) of hyper-osmotic conditions (920 and 1410mOsmol/kg) than wombat spermatozoa. F-actin was localised using a monoclonal antibody but only found in the wombat sperm head. When koala and wombat spermatozoa were exposed to media of varying osmolality, cytochalasin D had no beneficial effect on sperm survival (% intact plasma membranes). This study has demonstrated that wombat spermatozoa are highly tolerant of cryopreservation when compared to koala sperm but that spermatozoa from both species show greatest post-thaw survival when frozen slowly in 14% glycerol. Koala sperm are also particularly susceptible to hyper-osmotic environments but lack of detectable F-actin in the koala spermatozoan suggests that poor cryopreservation success in this species is unlikely to be associated with F-actin induced plasma membrane inflexibility.

Pregnancy loss in lesbian and bisexual women: An online survey of experiences

Background: Although pregnancy loss is a distressing health event for many women, research typically equates women’s experiences of pregnancy loss to ‘married heterosexual women’s experiences of pregnancy loss’. The objective of this study was to explore lesbian and bisexual women’s experiences of miscarriage, stillbirth and neonatal death. Methods: This study analysed predominantly qualitative online survey data from 60 non-heterosexual, mostly lesbian, women from the UK, USA, Canada and Australia. All but one of the pregnancies was planned. Most respondents had physically experienced one early miscarriage during their first pregnancy, although a third had experienced multiple losses. Results: The analysis highlights three themes: processes and practices for conception; amplification of loss; and health care and heterosexism. Of the respondents, 84% conceived using donor sperm; most used various resources to plan conception and engaged in preconception health care. The experience of loss was amplified due to contextual factors and the investment respondents reported making in impending motherhood. Most felt that their loss(es) had made a ‘significant’/‘very significant’ impact on their lives. Many respondents experienced health care during their loss. Although the majority rated the overall standard of care as ‘good’/‘very good’/‘outstanding’, a minority reported experiencing heterosexism from health professionals. Conclusions: The implications for policy and practice are outlined. The main limitation was that the inflexibility of the methodology did not allow the specificities of women’s experiences to be probed further. It is suggested that both coupled and single non-heterosexual women should be made more visible in reproductive health and pregnancy loss research.

The development of a multi-function computer-assisted instruction system using a hierarchical database structure as the lesson compendium.

Computer-Based Learning systems of one sort or another have been in existence for almost 20 years, but they have yet to achieve real credibility within Commerce, Industry or Education. A variety of reasons could be postulated for this, typically: - cost - complexity - inefficiency - inflexibility - tedium Obviously different systems deserve different levels and types of criticism, but it still remains true that Computer-Based Learning (CBL) is falling significantly short of its potential. Experience of a small, but highly successful CBL system within a large, geographically distributed industry (the National Coal Board) prompted an investigation into currently available packages, the original intention being to purchase the most suitable software and run it on existing computer hardware, alongside existing software systems. It became apparent that none of the available CBL packages were suitable, and a decision was taken to develop an in-house Computer-Assisted Instruction system according to the following criteria: - cheap to run; - easy to author course material; - easy to use; - requires no computing knowledge to use (as either an author or student) ; - efficient in the use of computer resources; - has a comprehensive range of facilities at all levels. This thesis describes the initial investigation, resultant observations and the design, development and implementation of the SCHOOL system. One of the principal characteristics c£ SCHOOL is that it uses a hierarchical database structure for the storage of course material - thereby providing inherently a great deal of the power, flexibility and efficiency originally required. Trials using the SCHOOL system on IBM 303X series equipment are also detailed, along with proposed and current development work on what is essentially an operational CBL system within a large-scale Industrial environment.

Strategic planning as communicative process

This thesis looks at the construction of a strategic plan within a British university (Unico). After a change in leadership, the well-known strategic planning sequence was adopted to set directions according to Unico’s three Missions, followed by the development of respective goals and measures. The evolving strategic content coincided with the development of Unico’s strategic plan. I was able to follow Unico’s planning efforts over 10 months, from first planning meeting to completion of its strategic plan. The main data source provided non-participant observation (n = 25) and ten versions of Unico’s strategic plan. Additionally, seventy-six interviews were held with participants at various points. In order to examine the strategic plan’s construction, I reconceptualised strategic planning as a communicative process consisting of oral talk and written text. Through this interplay strategic planning activities come in to being. Such reconceptualisation provided a conceptual framework to study the in situ interactions without neglecting contextual characteristics embedding the communicative process. Strategic plans are currently seen as promoting inflexibility and reinforcing the institutional nature of formal strategic planning. Adopting dialogism, as advocated by Bakhtin and Ricoeur, this research provides novel insights into the dialogic of strategy talk and strategy text, such as a strategic plan. Findings illustrated that a strategic plan production cycle provided a meaning making platform for its participants. Through recurrently amending the plan, its content became increasingly specific while at the same time reflecting agreed terminology. This thesis offers an alternative view on strategic planning, elaborates on the strategy-as-practice perspective, focusing on the under-explored area of individuals’ interactions at the micro level, and elaborates on the dialogic of text and agency/conversation, distinguishing between talk and text.

XML storage and retrieval using the semantic binary object -oriented database system (SEM-ODB)

Over the past five years, XML has been embraced by both the research and industrial community due to its promising prospects as a new data representation and exchange format on the Internet. The widespread popularity of XML creates an increasing need to store XML data in persistent storage systems and to enable sophisticated XML queries over the data. The currently available approaches to addressing the XML storage and retrieval issue have the limitations of either being not mature enough (e.g. native approaches) or causing inflexibility, a lot of fragmentation and excessive join operations (e.g. non-native approaches such as the relational database approach). ^ In this dissertation, I studied the issue of storing and retrieving XML data using the Semantic Binary Object-Oriented Database System (Sem-ODB) to leverage the advanced Sem-ODB technology with the emerging XML data model. First, a meta-schema based approach was implemented to address the data model mismatch issue that is inherent in the non-native approaches. The meta-schema based approach captures the meta-data of both Document Type Definitions (DTDs) and Sem-ODB Semantic Schemas, thus enables a dynamic and flexible mapping scheme. Second, a formal framework was presented to ensure precise and concise mappings. In this framework, both schemas and the conversions between them are formally defined and described. Third, after major features of an XML query language, XQuery, were analyzed, a high-level XQuery to Semantic SQL (Sem-SQL) query translation scheme was described. This translation scheme takes advantage of the navigation-oriented query paradigm of the Sem-SQL, thus avoids the excessive join problem of relational approaches. Finally, the modeling capability of the Semantic Binary Object-Oriented Data Model (Sem-ODM) was explored from the perspective of conceptually modeling an XML Schema using a Semantic Schema. ^ It was revealed that the advanced features of the Sem-ODB, such as multi-valued attributes, surrogates, the navigation-oriented query paradigm, among others, are indeed beneficial in coping with the XML storage and retrieval issue using a non-XML approach. Furthermore, extensions to the Sem-ODB to make it work more effectively with XML data were also proposed. ^

Psychologische Inflexibiliteit bij Kinderen: Invloed op de Relatie tussen en de Samenhang met Gepest worden en (Sociale) Angst

Pesten komt voor op alle scholen en kan psychosociale gevolgen hebben zoals (sociale) angst klachten. Op cognitieve gedragstherapie gebaseerde interventies hebben dikwijls de voorkeur bij behandeling van de klachten. De cognitieve vaardigheden van kinderen van 8 tot 11 jaar schieten echter soms tekort om optimaal te kunnen profiteren van cognitieve therapie. Acceptance and Commitment Therapy (ACT) zet in op het vergroten van de psychologische flexibiliteit en is mogelijk een geschikte alternatieve therapie voor kinderen. In de huidige studie werd onderzocht of psychologische inflexibiliteit een onderliggend probleem vormt bij kinderen die angsten hebben of dat gepest worden de kwetsbaarheid voor psychologische inflexibiliteit vergroot. Er werd een positieve samenhang tussen de variabelen psychologische inflexibiliteit, (sociale) angst en gepest worden verwacht. Tevens werd verwacht dat de positieve samenhang tussen gepest worden en (sociale) angst wordt gemodereerd door psychologische inflexibiliteit. Aan 126 kinderen, 66 jongens en 60 meisjes in de leeftijd van 8 tot 11 jaar, afkomstig van basisscholen in Zuid-Nederland werd door de ouders toestemming verleend voor deelname. Eenmalig werden een drietal zelfrapportage vragenlijsten klassikaal aan de kinderen voorgelegd. (Sociale) angst werd gemeten met de Screen for Child Anxiety Related Emotional Disorders-71 (SCARED-71), gepest worden werd gemeten met de Personal Experience Checklist-32 (PECK-32) en psychologische inflexibiliteit werd gemeten met de Avoidance and Fusion Questionnaire for Youth (AFQ-Y). Er werd een positieve samenhang gevonden tussen psychologische inflexibiliteit, (sociale) angst en gepest worden. Een moderatie effect van psychologische inflexibiliteit op de relatie tussen gepest worden en (sociale) angstklachten werd niet gevonden. De huidige studie bevestigt dat psychologische inflexibiliteit een onderliggend probleem vormt voor kinderen met angsten of kinderen die gepest worden. De gevonden verbanden bleken sterker voor angst als algemene trek dan voor sociale angst. Geslacht werd ter controle meegenomen in de analyses, maar verschillen tussen jongens en meisjes werden niet gevonden. ACT vermindert de psychologische inflexibiliteit door het versterken van de psychologische flexibiliteit. De verwachting dat de inzet van ACT de angstklachten en de gevolgen van het gepest worden bij kinderen kan verminderen wordt middels deze studie ondersteund. Verklaringen, beperkingen en relevantie worden besproken evenals suggesties voor verder onderzoek.

The role of the National Audit Office in Private Finance Initiative endurance

The Private Finance Initiative (PFI) has become one of the UK’s most contentious public policies. Despite New Labour’s advocacy of PFI as a means of achieving better value for money, criticisms of PFI have centred on key issues such as a lack of cost effectiveness, exaggerated pricing of risk transfers, excessive private sector profits, inflexibility and cumbersome administrative arrangements. Nevertheless, PFI has persisted as a key
infrastructure procurement method in the UK and has been supported as such by successive governments, as well as influencing policy in the Republic of Ireland and other European Nations. This paper explores this paradoxical outcome in relation to the role played in the UK by the National Audit Office (NAO). Under pressure to justify its support for PFI, the Blair government sought support for its policies by encouraging the NAO to investigate issues relating to PFI as well as specific PFI projects. It would have been expected that in fulfilling its role as independent auditor, the NAO would have examined whether PFI projects could have been delivered more efficiently, effectively or economically through other means. Yet, in line with earlier research, we find evidence that the NAO failed to comprehensively assess
key issues such as the value for money of PFI projects, and in so doing effectively acted as a legitimator of PFI policy. Using concepts relating to legitimacy theory and the idea of framing, our paper looks into 67 NAO private finance reports published between 1997 and 2011, with the goal of identifying the preferences, values and ideology underpinning the
NAO’s view on PFI during this period. Our analysis suggests that the NAO sought to legitimise existing PFI practices via a selective framing of problems and questions. Utilising a longitudinal approach, our analysis further suggests that this patterns of selective framing persisted over an extended time period during which fundamental parameters of the policy (such as contract length, to name one of the most important issues) were rarely addressed.
Overall the NAO’ supportive stance toward PFI seems to have relied on 1) a focused on positive aspects of PFI, such as on time delivery or lessons learned, and 2) positive comments on aspects of PFI that were criticised elsewhere, such as the lack of flexibility of underlying contractual arrangements. Our paper highlights the possibility that, rather than providing for a critical assessment of existing policies, national auditing bodies can
contribute to the creation of legitimatory environments. In terms of accounting research we would suggests that the objectivity and independence of accounting watchdogs should not be taken for granted, and that instead a critical investigation of the biases which can characterise these bodies can contribute to a deeper understanding of the nature of lobbying networks in the modern state.

Inflexibilidade Psicológica

O presente trabalho, destinou-se à validação do Avoidance and Fusion Questionnaire for Youth - AFQ- Y( Greco, Baer, & Lambert, 2008), traduzido por Questionário de Evitamento Experiencial e Fusão Cognitiva para Adolescentes. Isto porque, na prática clínica, se verifica uma escassez de instrumentos de auto-resposta que avaliam estes contructos, caracterizadores da inflexibilidade psicológica. A amostra do nosso estudo consiste em 461 adolescentes, com idades compreendidas entre os 12 e os 18 anos, a frequentar o 3º ciclo do ensino básio e ensino secundário de escolas situadas em meio rural e urbano. Para além do citado instrumento a validar, os jovens preencheram também outras medidas de sintomas psicopatológicos e de percepção do seu auto-conceito social; nomeadamente, o Inventário Depressivo para Crianças (CDI; Kovacs, 1985), a Escala Revista de Ansiedade Manifesta para Crianças (RCMAS; Reynolds & Richmond, 1978) e a Escala de Comparação Social (SCS; Allan, & Gilbert, 1995), bem como uma medida de um construto semelhante referente à aceitação e mindfulness em crianças(CAMM; Greco, Baer & Lambert, 2008). Os resultados obtidos mostram que o questionário possui uma boa consistência interna, uma adequada estabilidade temporal, assim como uma boa validade. Sugerem ainda tratar-se de uma escala unidimensional. Estes dados permitem o avanço da psicologia, no que diz respeito à prática clínica com adolescentes, nomeadamente no domínio das chamadas terapias de terceira geração em Portugal. São apresentados e discutidos os dados normativos para a população portuguesa. Não obstante às limitações apontadas, os resultados sugerem que o AFQ-Y é um questionário útil na avaliação da inflexibilidade psicológica em adolescentes. /
