All about me: Disclosure in online social networking profiles: The case of FACEBOOK

The present research examined disclosure in online social networking profiles (i.e., FACEBOOK™). Three studies were conducted. First, a scoring tool was developed in order to comprehensively assess the content of the personal profiles. Second, grouping categories (default/standard information, sensitive personal information, and potentially stigmatizing information) were developed to examine information pertinent to identity threat, personal and group threat. Third, a grouping strategy was developed to include all information present in FACEBOOK™, but to organize it in a meaningful way as a function of the content that was presented. Overall, approximately 25% of all possible information that could potentially be disclosed by users was disclosed. Presenting personal information such as gender and age was related to disclosure of other sensitive and highly personal information. Age and relationship status were important factors in determining disclosure. As age increased, the amount of personal information in profiles decreased. Those seeking a relationship were at greatest risk of threat, and disclosed the greatest amount of highly sensitive and potentially stigmatizing information. These implications of these findings with respect to social and legal threats, and potential means for identifying users placing themselves at greatest risk, are discussed.     

A Process Pattern Model for Tackling and Improving Big Data Quality

Data seldom create value by themselves. They need to be linked and combined from multiple sources, which can often come with variable data quality. The task of improving data quality is a recurring challenge. In this paper, we use a case study of a large telecom company to develop a generic process pattern model for improving data quality. The process pattern model is defined as a proven series of activities, aimed at improving the data quality given a certain context, a particular objective, and a specific set of initial conditions. Four different patterns are derived to deal with the variations in data quality of datasets. Instead of having to find the way to improve the quality of big data for each situation, the process model provides data users with generic patterns, which can be used as a reference model to improve big data quality.     

A Meta-Analytic Review of Stopping Performance in Attention-Deficit/Hyperactivity Disorder: Deficient Inhibitory Motor Control?

This review discusses whether deficient inhibitory motor control is the core deficit of attention-deficit/hyperactivity disorder (ADHD). Inhibitory motor control is commonly assessed using the stop-signal paradigm. Since the last meta-analysis that was performed, 33 new studies have appeared. The current meta-analysis revealed a significant difference between ADHD patients and matched controls in stop latency (stop-signal reaction time) in both children and adults. Basic reaction time was significantly longer in children with ADHD, but not in adults, and there was a significant interaction between the elongation of the latency to stop and to respond in adults, but not in children. Deficient inhibitory motor control may be less crucial in children than in adults with ADHD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

GAS-LIQUID DISPERSION WITH PITCHED BLADE TURBINES

The performance of pitched blade turbines in a gas-liquid dispersion has been studied. The two-phase hydrodynamics, gassed power consumption and mass transfer properties have been examined using six blade open turbines with blade angles from 30 to 60 degrees to the horizontal, mounted for down flow.

There are two distinct regimes by which gas leaving the sparger reaches the impeller: at low gas rates this is indirect via the recirculation loops, while at higher gas flow rates the flow is direct.

The transition between these regimes is reflected in power consumption and mass transfer characteristics and is related to the formation of large cavities behind the blades. It was also concluded that, with respect to mass transfer efficiency, a pitched blade turbine is at least as good as a Rushton turbine.     

Approaches to lung cancer treatment using the CD3 x EGP-2-directed bispecific monoclonal antibody BIS-1

OBJECTIVES: To evaluate the clinical importance of the interaction between carbamazepine (CBZ) and dextropropoxyphene in elderly patients. METHODS: All patients (n = 7263) in Gothenburg, Sweden, who were part of a drug-dispensing programme, were included in the study. Eight per cent of the patients took CBZ and 18% took dextropropoxyphene, continuously. Patients who used a combination of these drugs were compared with patients who took only CBZ or dextropropoxyphene or neither of the two drugs. These four groups of patients were matched to each other with reference to gender, age and concomitant medication, which finally resulted in 21 patients in each group. A questionnaire with 30 symptoms of well-being, including symptoms typical of adverse effects of CBZ, were answered by the patients with the help of a registered nurse. Venous blood samples were drawn from the patients for the analysis of CBZ, its metabolite CBZ 10,11-epoxide (CBZ-E) and dextropropoxyphene. RESULTS: The doses of CBZ and dextropropoxyphene were lower among patients who used the combination of the two drugs than among those who only used one of the drugs. The mean level of CBZ in serum (S-CBZ) was, however, significantly higher and the level of CBZ-E in serum (S-CBZ-E) significantly lower among the patients who used the combination of CBZ and dextropropoxyphene, thus indicating an inhibition of the metabolism of CBZ. The prevalence of symptoms indicating side effects of CBZ was significantly higher in the group of patients who used both drugs. CONCLUSION: This study has shown that the combination of CBZ and dextropropoxyphene is hazardous in elderly patients and should be used with caution.

Electronic monitoring-based counseling to enhance adherence among HIV-infected patients: A randomized controlled trial.

Objective: To investigated the effectiveness of an adherence intervention (AIMS) designed to fit HIV-clinics' routine care procedures. Design: Through block randomization, patients were allocated to the intervention or control group. The study included 2 months baseline measurement, 3 months intervention, and 4 months follow-up. HIV-nurses delivered a minimal intervention (“adherence sustaining”) to patients scoring >95% adherence at baseline, and an intensive intervention (“adherence improving”) to patients with     

Standard care quality determines treatment outcomes in control groups of HAART-adherence intervention studies: Implications for the interpretation and comparison of intervention effects.

Objective: Clinical trials of behavioral interventions seek to enhance evidence-based health care. However, in case the quality of standard care provided to control conditions varies between studies and affects outcomes, intervention effects cannot be directly interpreted or compared. The objective of the present study was to examine whether standard care quality (SCQ) could be reliably assessed, varies between studies of highly active antiretroviral HIV-adherence interventions, and is related to the proportion of patients achieving an undetectable viral load (“success rate”). Design: Databases were searched for relevant articles. Authors of selected studies retrospectively completed a checklist with standard care activities, which were coded to compute SCQ scores. The relationship between SCQ and the success rates was examined using meta-regression. Main Outcome Measures: Cronbach’s alpha, variability in SCQ, and relation between SCQ and success rate. Results: Reliability of the SCQ instrument was high (Cronbach’s alpha = .91). SCQ scores ranged from 3.7 to 27.8 (total range = 0–30) and were highly predictive of success rate (p = .002). Conclusions: Variation in SCQ provided to control groups may substantially influence effect sizes of behavior change interventions. Future trials should therefore assess and report SCQ, and meta-analyses should control for variability in SCQ, thereby producing more accurate estimates of the effectiveness of behavior change interventions.
