Normative data on cognitive measures of depression.
The assessment of cognition and cognitive change is important for case conceptualization, monitoring the efficacy of specific interventions, and evaluating treatment outcome in cognitive-behavioral therapy. Unfortunately, a paucity of normative data exists on cognitive measures used for psychotherapy outcome research in depression, and little information is available to guide a practitioner\u27s understanding of the magnitude and clinical significance of a patient\u27s cognitive change. This article presents normative data on 6 self-report instruments that assess negative and positive automatic thoughts, hopelessness, cognitive biases and errors, and dysfunctional attitudes. Normative data were derived from studies published from the date of inception of a given cognitive index to the year 2000. Recommendations for the use of these normative data are provided
A meta-analysis of CBT for pathological worry among clients with GAD.
Previous meta-analyses assessing the effectiveness of Cognitive Behavioural Therapy (CBT) for Generalized Anxiety Disorder (GAD) used general measures of anxiety to assess symptom severity and improvement (e.g., Hamilton Anxiety Ratings Scale or a composite measure of anxiety). While informative, these studies do not provide sufficient evidence as to whether CBT significantly reduces the cardinal symptom of GAD: pathological worry. The current meta-analysis employed stringent inclusion criteria to evaluate relevant outcome studies, including the use of the Penn State Worry Questionnaire as the main outcome variable. Results showed a large overall effect size (ES) that was moderated by age and modality of treatment. Specifically, the largest gains were found for younger adults and for individual treatment. Analyses also revealed overall maintenance of gains at 6- and 12-month follow-up. Clinical implications of different treatment packages are discussed, as well as potential explanations for the differential effectiveness of CBT
Measuring Cognitive Errors: Initial Development of the Cognitive Distortions Scale (CDS)
The ability to assess and correct biases in thinking is central to cognitive-behavioral therapy. Although measures of cognitive distortions exist, no measure comprehensively assesses the cognitive errors that are typically cited in the literature. The development and initial validation of the Cognitive Distortions Scale (CDS), a questionnaire that measures the tendency to make 10 cognitive distortions (e.g., mindreading, catastrophizing, all-or-nothing thinking) as they occur in interpersonal and achievement domains, is described. Across two studies, undergraduate students (n = 318) completed the CDS and other clinically relevant measures. The CDS and its two subscales appear to exhibit good psychometric properties; however, a factor analysis supported the use of a one-factor solution. Additional analyses suggested that some errors occur more frequently in some domains than others and that some errors may have more clinical significance than others. Notwithstanding issues inherent in measuring cognitive errors, and study limitations, the CDS appears to be a promising new measure of cognitive distortion, with good research and clinical potential
PKS 0537-286, carrying the information of the environment of SMBHs in the early Universe
We present the results of a multifrequency campaign on the high-redshift (z =
3.1) blazar PKS 0537-286. The source was observed at different epochs from 2006
to 2008 with INTEGRAL and Swift, and nearly simultaneously with ground-based
near-IR/optical telescopes. The SEDs are compatible with a model based on
synchrotron radiation and external inverse Compton scattering. The campaign
gives an insight into the physical environment of the blazar.Comment: 8 pages, 5 figures, accepted for publication in A&
The status quo of research on entrepreneurial orientation : conversational landmarks and theoretical scaffolding
This research aims to gain a deeper appreciation of where the entrepreneurial orientation (EO) conversation has gained momentum based upon an analysis of its key conversational landmarks and the studies which have thus far provided its principal theoretical scaffolding. Drawing upon a bibliometric analysis of 62,499 citations from all 822 publications on EO existing so far, thereby building the most comprehensive overview of EO studies collected to date, we are able to identify which studies, journals, and disciplines have offered critical landmarks within the conversation. Moreover, we categorize these influential landmark studies into four primary areas, namely âDefining piecesâ, âMethods and measurementâ, âContingenciesâ, and âImpactâ, and discuss how prominent landmarks within the EO conversation have created the current theoretical scaffolding upon which EO research is now building. Notably, our study observes Schumpeter (1934) theory of entrepreneurship and innovation as âcreative destructionâ as well as Barney (1991) resource-based view (RBV) as landmarks within EOâs present theoretical scaffolding
A systematic review of school-based sexual health interventions to prevent STI/HIV in sub-Saharan Africa
Background
The HIV/AIDS epidemic remains of global significance and there is a need to target (a) the adolescent age-groups in which most new infections occur; and (b) sub-Saharan Africa where the greatest burden of the epidemic lies. A focused systematic review of school-based sexual health interventions in sub-Saharan Africa to prevent HIV/AIDS and Sexually Transmitted Infections (STI) in this age group was therefore conducted.
Methods
Searches were conducted in Medline, Embase, Cinahl and PsychINFO according to agreed a priori criteria for studies published between 1986 and 2006. Further searches were conducted in UNAIDS and WHO (World Health Organization) websites, and 'Google'. Relevant journals were hand-searched and references cited in identified articles were followed up.
Data extraction and quality assessment was carried out on studies selected for full text appraisal, and results were analysed and presented in narrative format.
Results
Some 1,020 possible titles and abstracts were found, 23 full text articles were critically appraised, and 12 articles (10 studies) reviewed, reflecting the paucity of published studies conducted relative to the magnitude of the HIV epidemic in sub-Saharan Africa. Knowledge and attitude-related outcomes were the most associated with statistically significant change. Behavioural intentions were more difficult to change and actual behaviour change was least likely to occur. Behaviour change in favour of abstinence and condom use appeared to be greatly influenced by pre-intervention sexual history.
Conclusion
There is a great need in sub-Saharan Africa for well-evaluated and effective school-based sexual health interventions
Entrepreneurial orientation of traditional and modern cultural organisations: cases in George Town UNESCO World Heritage Site
George Town World Heritage Site in Penang, Malaysia is well-endowed with creative and cultural resources, and has recently witnessed a rise in relevant rise in creative and cultural activities. This study examines how 'innovation culture' is inculcated and embedded within two local organisations with distinct approaches to innovation. This examination adopts and adapts the concept of Entrepreneurial Orientation, using three constructs: i) innovativeness, ii) risk-taking and iii) pro-activeness. This study administered a purely qualitative research approach by conducting in-depth semi-structured interviews and archival study of the chosen case organisations and their networks. The novelty of this research resides in the choice of case study organisations chosen (i.e. traditional versus modern) where a comparative approach was used to compare and contrast innovation culture and gauge the extent upon which entrepreneurship orientation constructs are prevalent and thriving in these organisations. By documenting the linkages in their value chains, this study managed to understand their resulting social networks and whether such network fosters the incubation of an innovation cluster for the local creative and cultural sectors. This study concluded that traditional cultural organisations tend to be more cautious and even passive in their business approach and decision-making processes, while modern and newer cultural and creative organisations lean towards a more active and dynamic outlook, albeit sometimes constrained by lack of resources, i.e. funding and facilities, as well as impeded by the nature of their informality. These findings can contribute towards shaping pragmatic human resource and creative industry policies for city planners and policy makers, particularly in the George Town World Heritage Site, as well as serving as point of reference for other world heritage sites in the world
Universal Rights and Wrongs
This paper argues for the important role of customers as a source of competitive advantage and firm growth, an issue which has been largely neglected in the resource-based view of the firm. It conceptualizes Penroseâs (1959) notion of an âinside trackâ and illustrates how in-depth knowledge about established customers combines with joint problem-solving activities and the rapid assimilation of new and previously unexploited skills and resources. It is suggested that the inside track represents a distinct and perhaps underestimated way of generating rents and securing long-term growth. This also implies that the sources of sustainable competitive advantage in important respects can be sought in idiosyncratic interfirm relationships rather than within the firm itself
Entrepreneurial orientation and the business performance of SMEs: a quantitative study from the Netherlands
Entrepreneurial Orientation (EO) is often mentioned as an antecedent of growth, competitive advantage and superior performance, and prior empirical research has often shown a positive relationship between EO and performance appears to exist. However, an important question that remains unanswered is what effect EO might have on firm performance during periods of economic crisis, and the severe environmental turbulence that accompany such crises. This research is a first investigation towards the effects of EO on the performance of small and medium sized firms during the current global economic crisis. In this study we use the multidimensional model of EO and test a series of hypotheses pertaining to its performance effects using survey data gathered from 164 Dutch SMEs. The present research shows that proactive firm behavior positively contributes to SME performance during the economic crisis. We further show that innovative SMEs do perform better in turbulent environments, but those innovative SMEs should minimize the level of risk and should take action to avoid projects that are too risky
Moderating influences on the firm's strategic orientation-performance relationship
This paper is focused on the factors that moderate the relationship between firm's strategic orientation and performance in small and medium-sized firms. Much prior research has focused simply on identifying environmental conditions conducive to the effectiveness of the strategic orientation approach. However, recent research has called for studies focused on investigating internal moderators of the strategic orientation-performance relationship. As a result, we propose a contingency framework, considering how corporate and competitive strategies, top management characteristics, and environmental conditions may moderate this relationship. Based on a survey of 295 small and medium sized enterprises pertaining to seven manufacturing sectors, our study shows that the positive influence of firm's strategic orientation may be moderated by the environment conditions, the previous experience of top management team, and the corporate and competitive strategies developed by the firm
