A Systematic Review of Online Sex Addiction and Clinical Treatments Using CONSORT Evaluation
No full textResearchers have suggested that the advances of the Internet over the past two decades have gradually eliminated traditional offline methods of obtaining sexual material. Additionally, research on cybersex and/or online sex addictions has increased alongside the development of online technology. The present study extended the findings from Griffiths’ (2012) systematic empirical review of online sex addiction by additionally investigating empirical studies that implemented and/or documented clinical treatments for online sex addiction in adults. A total of nine studies were identified and then each underwent a CONSORT evaluation. The main findings of the present review provide some evidence to suggest that some treatments (both psychological and/or pharmacological) provide positive outcomes among those experiencing difficulties with online sex addiction. Similar to Griffiths’ original review, this study recommends that further research is warranted to establish the efficacy of empirically driven treatments for online sex addiction
Woud: Trek je even terug in je concentratiebubbel
No full textHet was zo’n zonnige lentedag; heerlijk om lekker buiten te zijn. Ik zat binnen, in een vergadering – met de nodige moeite om mijn aandacht erbij te houden. Liever keek ik door het raam naar kersenbloesems. Afgeleid raken, wegdromen ofjuist onrustig zijn en niet stil kunnen zitten. Herkenbaar? Vast wel; iedereen heeft wel eens moeite om zich te concentreren. Maar voor sommige kinderen is dit een dagelijkse worsteling. Hoe ga je daar op een goede manier mee om in eenklaslokaal, een omgeving met constante prikkels en afleiding?

Risk Analysis for Autonomous Underwater Vehicle Operations in Extreme Environments
No full textAutonomous underwater vehicles (AUVs) are used increasingly to explore hazardous marine environments. Risk assessment for such complex systems is based on subjective judgment and expert knowledge as much as on hard statistics. Here, we describe the use of a risk management process tailored to AUV operations, the implementation of which requires the elicitation of expert judgment. We conducted a formal judgment elicitation process where eight world experts in AUV design and operation were asked to assign a probability of AUV loss given the emergence of each fault or incident from the vehicle's life history of 63 faults and incidents. After discussing methods of aggregation and analysis, we show how the aggregated risk estimates obtained from the expert judgments were used to create a risk model. To estimate AUV survival with mission distance, we adopted a statistical survival function based on the nonparametric Kaplan-Meier estimator. We present theoretical formulations for the estimator, its variance, and confidence limits. We also present a numerical example where the approach is applied to estimate the probability that the Autosub3 AUV would survive a set of missions under Pine Island Glacier, Antarctica in January–March 2009
Health outcomes of children born to mothers with chronic kidney disease: a pilot study
No full textThis study aimed to study the health of children born to mothers with chronic kidney disease. Twenty-four children born to mothers with chronic kidney disease were compared with 39 matched control children born to healthy mothers without kidney disease. The well-being of each child was individually assessed in terms of physical health, neurodevelopment and psychological health. Families participating with renal disease were more likely to be from lower socio-economic backgrounds. Significantly fewer vaginal deliveries were reported for mothers with renal disease and their infants were more likely to experience neonatal morbidity. Study and control children were comparable for growth parameters and neurodevelopment as assessed by the Griffiths scales. There was no evidence of more stress amongst mothers with renal disease or of impaired bonding between mother and child when compared to controls. However, there was evidence of greater externalizing behavioral problems in the group of children born to mothers with renal disease. Engaging families in such studies is challenging. Nonetheless, families who participated appreciated being asked. The children were apparently healthy but there was evidence in this small study of significant antenatal and perinatal morbidity compared to controls. Future larger multi-center studies are required to confirm these early findings
Londen laat zien: verstedelijking kun je privaat bekostigen

The fire resistance of high-strength concrete containing natural zeolites
No full textMore sustainable and environmentally friendly concretes are essential to reduce the climatic and environmental impact of the growing demand for concrete to fuel urban sprawl. This manuscript reports on an experimental study designed to test the fire resistance of one such concrete, prepared to contain natural zeolite-bearing tuff. The fire resistance of concretes containing natural zeolites has received little attention and is therefore poorly understood. Relative reductions in residual uniaxial compressive strength as a function of increasing temperature (up to 1000 °C) were very similar for the reference concrete (containing no tuff) and the tuff-bearing concrete. These data can be explained by the similar influence of high-temperature on the chemical (dehydroxylation reactions) and physical (microcracking and porosity) properties of both concretes. The satisfactory performance of the concrete containing natural zeolites following fire is welcome owing to the economic, climatic, and environmental benefits of using natural pozzolan and aggregate substitutes
