Business Ownership and Sectoral Growth

We investigate the development of business ownership (self-employment) rates over time at the sectoral level and the effect of these rates on sectoral output growth. In an earlier exercise, carree et al. (2002) presented an analysis of the interrelationship between economy-wide business ownership rates and economic development. Their analysis raised an important research question: to what extent do differences in business ownership rates at the economy-wide level reflect differences in the sectoral structures of economies or differences in business ownership rates at the sectoral level? the current article investigates this question making use of a sectoral data base of 21 oecd countries for the period 1970-98. Estimation results suggest that there is, on average, a too low business ownership rate in manufacturing and a too high business ownership rate in services

Assessing recovery after cold challenge and thumb involvement can help to rule out systemic sclerosis in patients presenting with Raynaud?s phenomenon

Objective: Our aim was to study whether recovery from a Raynaud?s attack and involvement of the thumb are differentiators for systemic sclerosis (SSc) in patients with Raynaud?s phenomenon (RP). Method: A stepwise cooling and recovery procedure was performed, provoking an RP attack, in patients with primary Raynaud?s phenomenon (PRP, n =?68) and SSc (n?=?18). During the procedure, the perfusion of all five fingers during cooling and recovery was assessed by photoelectric plethysmography. Results: In SSc patients, perfusion after 10?min in one or more fingers was more frequently not restored than in PRP patients (p?=?0.001), with a negative predictive value of 98%. The thumb was more frequently involved in SSc patients (p?=?0.036), with a negative predictive value of 95%. Positive predictive values were low. Conclusions: In patients with RP, when there is restoration of perfusion in all fingers after 10?min or when the thumb is spared, the presence of an underlying SSc is very unlikely. Although these results need to be validated in a clinical setting in a larger prospective study, these signs can help physicians to select additional testing for SSc in RP patients

The limits of conscious deception detection: when reliance on false deception cues contributes to inaccurate judgments

People are generally too trusting, which decreases their ability to detect deceit. This suggests that distrust could enhance our deception detection abilities. Yet, a state of distrust may induce deliberative conscious thought. This mode of thinking has been related to worse complex decision making. Hence, we investigate whether contextual distrust decreases the ability to detect deceit via the stronger reliance on consciously held beliefs about which cues betray deception. In two studies, participants were asked to judge videos of either deceiving or truth telling targets. Contextual distrust was manipulated by asking participants to squint their eyes (distrust) or to round their eyes (trust) while watching the videos. Participants’ judgments of targets being deceptive or truthful were measured (Studies 1 and 2) and they were asked on what basis they made these judgments (Study 2). Results showed that distrust especially hampers the detection of truth, which is partly due to more reliance on false beliefs about deception cues. These results corroborate the idea that deliberative conscious information processing may hinder truth detection, while intuitive information processing may facilitate it.Social decision makin

Measuring client experiences in maternity care under change

Background Maternity care is an integrated care process, which consists of different services, involves different professionals and covers different time windows. To measure performance of maternity care based on clients' experiences, we developed and validated a questionnaire. Methods and Findings We used the 8-domain WHO Responsiveness model, and previous materials to develop a self-report questionnaire. A dual study design was used for development and validation. Content validity of the ReproQ-version-0 was determined through structured interviews with 11 pregnant women (≤28 weeks), 10 women who recently had given birth (≤12 weeks), and 19 maternity care professionals. Structured interviews established the domain relevance to the women; all items were separately commented on. All Responsiveness domains were judged relevant, with Dignity and Communication ranking highest. Main missing topic was the assigned expertise of the health professional. After first adaptation, construct validity of the ReproQ-version-1 was determined through a web-based survey. Respondents were approached by maternity care organizations with different levels of integration of services of midwives and obstetricians. We sent questionnaires to 605 third trimester pregnant women (response 65%), and 810 women 6 weeks after delivery (response 55%). Construct validity was based on: response patterns; exploratory factor analysis; association of the overall score with a Visual Analogue Scale (VAS), known group comparisons. Median overall ReproQ score was 3.70 (range 1-4) showing good responsiveness. The exploratory factor analysis supported the assumed domain structure and suggested several adaptations. Correlation of the VAS rating and overall ReproQ score (antepartum, postpartum) supported validity (r = 0.56; 0.59, p< 0.001 Spearman's correlation coefficient). Pre-stated group comparisons confirmed the expected difference following a good vs. adverse birth outcome. Fully integrated organizations performed slightly better (median = 3.78) than less integrated organizations (median = 3.63; p< 0.001). Participation rate of women with a low educational level and/or a non-western origin was low. Conclusions The ReproQ appears suitable for assessing quality of maternity care from the clients' perspective. Recruitment of disadvantaged groups requires additional non-digital approaches
