Deliberate practice among South African small business owners: Relationships with education,cognitive ability,knowledge, and success

The study examines antecedents and outcomes of deliberate practice activities in South African small businesses. Deliberate practice consists of individualized self‐regulated and effortful activities aimed at improving one's current performance level. Interview and questionnaire data from 90 South African business owners showed a direct impact of deliberate practice on entrepreneurial knowledge as well as an indirect effect on business growth via entrepreneurial knowledge. Cognitive ability and education were identified as antecedents of deliberate practice. Findings underline the importance of continuous proactive learning efforts in small business. The results of this study are relevant for policy makers, consultants, and credit providers.     

Free Will and Scientiphicalism

John McDowell, Richard Rorty, and Robert Brandom invoke Sellars's arguments against the Myth of the Given as having shown that the Given is nothing more than a myth. But most of Sellars's arguments attack logical atomism, not the framework of givenness as such. Moreover, they do not succeed. At crucial points the arguments confuse the perspectives of a knower and those attributing knowledge to a knower. Only one argument—the “inconsistent triad” argument—addresses the Myth of the Given as such, and there are several ways of escaping its conclusion. Invocations of Sellars's refutation of the Myth of the Given are empty.     

Defining Treatment Outcomes in Pediatric Obsessive-Compulsive Disorder Using a Self-Report Scale

This study examined benchmarks of treatment response and clinical remission on the Obsessive Compulsive Inventory–Child Version (OCI-CV) for youth with obsessive-compulsive disorder (OCD). Participants were 91 youth who enrolled in a randomized controlled trial that examined the benefit of augmenting cognitive behavior therapy (CBT) with either d-cycloserine or placebo. Youth completed the OCI-CV at baseline, Week 4 (prior to initiating exposure therapy), and posttreatment. Receiver operator curve (ROC) analyses examined optimal benchmarks for treatment response and clinical remission as identified by independent evaluators at the posttreatment assessment using the Clinical Global Impression (CGI) scales of Improvement (CGI-Improvement), Severity (CGI-Severity), and Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Optimal benchmarks for treatment response were a 20%–25% reduction in the OCI-CV total score. Meanwhile, optimal benchmarks for remission were a 55%–65% reduction in the OCI-CV total score and a posttreatment total score ≤ 6-8. OCI-CV benchmarks exhibited moderate agreement with the CY-BOCS for treatment response and clinical remission. Meanwhile, fair agreement was observed for response and remission with CGI scales. A lower pretreatment OCI-CV total score was associated with less agreement between classification approaches. Findings provide benchmarks for classifying treatment response and clinical remission in an efficient manner. Given the moderate agreement between the CY-BOCS and OCI-CV benchmarks, the OCI-CV may serve as a useful alternative when clinician-rated scales cannot be administered due to limited resources (e.g., time, training). Thus, evidence-based measurement can be incorporated to monitor therapeutic response and remission in clinical practice.     

Religious ideology, a neglected variable

Comments on an article by J. T. Jost, which presented interesting data relating some personality dimensions to voting patterns in the last three U.S. presidential elections. R. K. Unger is surprised that in his extensive review of the role of ideology, Jost ignored the role of religious ideology in political attitudes and voting behavior. There is ample evidence that level of religious observance (sometimes labeled religiosity, hierarchical religious beliefs, or religious fundamentalism) played a role in 2004 and earlier presidential elections. The relationship between religious ideology and political attitudes is correlational, and one needs to look further for an explanation of their impact. A number of studies indicate relationships between religious fundamentalism and what Jost has termed "system-justifying ideologies." Unger suggests that religiosity has been largely ignored by psychologists interested in social and political behaviors. It is quite possible that religiosity is related to the various personality dimensions discussed by Jost. But we cannot learn more about these potential connections if we continue to ignore the importance of religious ideology as a psychological variable.     

SAS and SPSS macros to calculate standardized Cronbach’s alpha using the upper bound of the phi coefficient for dichotomous items

Cronbach’s α is widely used in social science research to estimate the internal consistency of reliability of a measurement scale. However, when items are not strictly parallel, the Cronbach’s α coefficient provides a lower-bound estimate of true reliability, and this estimate may be further biased downward when items are dichotomous. The estimation of standardized Cronbach’s α for a scale with dichotomous items can be improved by using the upper bound of coefficient ϕ. SAS and SPSS macros have been developed in this article to obtain standardized Cronbach’s α via this method. The simulation analysis showed that Cronbach’s α from upper-bound ϕ might be appropriate for estimating the real reliability when standardized Cronbach’s α is problematic.     

Social network predictors of bullying and victimization

This study examined whether bullies, victims, and aggressive victims (those who are both bullies and victims) differed on classroom social network variables, gender, and ethnicity. Survey data were collected from a primarily Latino and Asian sample of 1,368 Southern California 6th graders (mean age = 11.3 years). Logistic regression analyses were performed to determine whether network characteristics and ethnicity were associated with each of the outcome variables. Consistent with social cognitive theory, friends' participation in aggressive behaviors was positively associated with being a bully or an aggressive victim, and negatively associated with being a victim. Consistent with social dominance theory, the number of friendship nominations received was negatively associated with being a victim. Female bullies received fewer friendship nominations, but had a higher proportion of reciprocated friendships. Victims were disproportionately Asian. The findings suggest that bullying prevention efforts targeting highly aggressive students may also diffuse to their friends, and that assertiveness training in handling aggressive situations may successfully combat bullying and aggression.     

Electrometric Studies of Sleep

The authors provided a differential test between stimulus-stimulus (S-S) and stimulus-response (S-R) theory predictions in regard to the roles that the constructs of expectancy and of fear play in maintaining classically conditioned fear responding within the context of a human conditioned-avoidance paradigm. After the participants had developed sustained avoidance responding, their shock electrodes and avoidance response apparatus were removed to enhance the cognitive expectancy that the conditioned stimulus (CS) would not be followed by the unconditioned stimulus (UCS). This manipulation of expectancy was successful in 96% of the participants. The study was conducted over a 2-day period and involved 1 experimental group and 3 control groups. During the test trials, the authors used autonomic and self-report indices of fear to assess the presence or absence of fear to the CS. The data disconfirmed the prediction of the S-S theory that fear to the CS would be extinguished. The authors discuss the implications of this finding for S-S theories and for approaches in cognitive behavior therapy.     

Is Time Perspective a Predictor of Anxiety and Perceived Stress? Some Preliminary Results from Greece

In the current studies, we explore the relationship between anxiety / perceived stress and time perspectives. Study 1 tested the relationship between the dimensions of the Zimbardo Time Perspective Inventory (ZTPI) and anxiety in a male sample. Study 2 examined the relationship between time perspectives and perceived stress in a sample of students. Both studies considered the Deviation of the Balanced Time Perspective (DBTP). In Study 1 psychiatrists of the Mental Health Centre of the Armed Forces in Athens diagnosed generalised anxiety in a number of male participants of the overall sample (n?=?204). All participants completed a validated Greek translation of the ZTPI. In Study 2 a sample of students (n?=?71) of Panteion University completed the Greek translations of the ZTPI and the Perceived Stress Scale (PSS-14 items). In Study 1 a negative correlation between Future orientation and anxiety was found. The DBTP was higher in persons with anxiety. In Study 2 the Past Negative and Present Fatalistic orientations correlated with high-perceived stress as assumed. Furthermore, high-perceived stress was associated with a higher DBTP. The ZTPI is particularly important for the explanation of perceived stress. DBTP, Past Negative and Present Fatalistic perspectives are important factors of influence. The measurement of anxiety should be re-examined.     

SYSTEMATIC EVALUATION OF VARIABLES THAT CONTRIBUTE TO NONCOMPLIANCE: A REPLICATION AND EXTENSION

The effects of time‐out and escape extinction were examined with 2 preschoolers after we identified variables that may have resulted in noncompliance. Results of a functional analysis showed that noncompliance was highest in the escape condition for both participants. During the treatment evaluation, escape extinction resulted in greater reductions in noncompliance relative to time‐out.
