TL;DR: There is a paucity of high-quality evidence regarding the effect of different dressings on the healing of superficial and partial thickness burn injuries and silver sulphadiazine was consistently associated with poorer healing outcomes than biosynthetic (skin substitute) dressings, silver-containing dressings and silicon-coated dressings.
Abstract: Background
An acute burn wound is a complex and evolving injury. Extensive burns produce systemic consequences, in addition to local tissue damage. Treatment of partial thickness burn wounds is directed towards promoting healing and a wide variety of dressings are currently available. Improvements in technology and advances in understanding of wound healing have driven the development of new dressings. Dressing selection should be based on their effects on healing, but ease of application and removal, dressing change requirements, cost and patient comfort should also be considered.
Objectives
To assess the effects of burn wound dressings on superficial and partial thickness burns.
Search methods
For this first update we searched The Cochrane Wounds Group Specialised Register (searched 8 November 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 10); Ovid MEDLINE (2008 to October Week 4 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, November 07, 2012); Ovid EMBASE (2008 to 2012 Week 44); AND EBSCO CINAHL (1982 to 2 November 2012).
Selection criteria
All randomised controlled trials (RCTs) that evaluated the effects of burn wound dressings on the healing of superficial and partial thickness burns.
Data collection and analysis
Two authors extracted the data independently using standardised forms. We assessed each trial for internal validity and resolved differences by discussion.
Main results
A total of 30 RCTs are included in this review. Overall both the quality of trial reporting and trial conduct were generally poor and meta analysis was largely precluded due to study heterogeneity or poor data reporting. In the context of this poor quality evidence, silver sulphadiazine (SSD) was consistently associated with poorer healing outcomes than biosynthetic (skin substitute) dressings, silver-containing dressings and silicon-coated dressings. Burns treated with hydrogel dressings appear to heal more quickly than those treated with usual care.
Authors' conclusions
There is a paucity of high-quality evidence regarding the effect of different dressings on the healing of superficial and partial thickness burn injuries. The studies summarised in this review evaluated a variety of interventions, comparators and clinical endpoints and all were at risk of bias. It is impossible to draw firm and confident conclusions about the effectiveness of specific dressings, however silver sulphadiazine was consistently associated with poorer healing outcomes than biosynthetic, silicon-coated and silver dressings whilst hydrogel-treated burns had better healing outcomes than those treated with usual care.

TL;DR: Differences in parent behaviors observed during the family discussions were reliably associated with the child's response to the ambiguous situation proposed after the family discussion, supporting a model of developmental anxiety and aggression that emphasizes the interaction of family processes and social-cognitive development in the child.
Abstract: Barrett, Rapee, Dadds, and Ryan (1996) described a phenomenon whereby family discussions magnified the style of children's problem solving in a way characteristic of their particular clinical diagnosis. That is, anxious children became more avoidant, aggressive children more aggressive, and nonclinic children more prosocial, after discussing ambiguous hypothetical situations with their parents. This study examined specific sequences of communications exchanged between parents and children hypothesized to underlie this family exacerbation of child cognitive style. Family discussions were videotaped and categorized for groups of anxious, aggressive, and nonclinic children and their parents. Results revealed differences between groups of parents in frequency of agreeing with and listening to their child and the frequency of pointing out positive consequences. Conditional probability analyses showed that parents of anxious children were more likely to reciprocate avoidance, while parents of nonclinic children were more likely to agree with and listen to prosocial plans from their child. Differences in parent behaviors observed during the family discussions were reliably associated with the child's response to the ambiguous situation proposed after the family discussion. Results support a model of developmental anxiety and aggression that emphasizes the interaction of family processes and social-cognitive development in the child.

TL;DR: In this paper, the authors conduct an econometric investigation of the existence of bubbles in the bitcoin market based on a recently developed technique that is robust in detecting bubbles, that of Phillips et al. (2013a).
Abstract: The creation of bitcoin heralded the arrival of digital or crypto-currency and has been regarded as a phenomenon. Since its introduction, it has experienced a meteoric rise in price and rapid growth accompanied by huge volatility swings, and also attracted plenty of controversies which even involved law enforcement agencies. Hence, claims abound that bitcoin has been characterized by bubbles ready to burst any time (e.g. the recent collapse of bitcoin’s biggest exchange, Mt Gox). This has earned plenty of coverage in the media but surprisingly not in the academic literature. We therefore fill this knowledge gap. We conduct an econometric investigation of the existence of bubbles in the bitcoin market based on a recently developed technique that is robust in detecting bubbles – that of Phillips et al. (2013a). Over the period 2010–2014, we detected a number of short-lived bubbles; most importantly, we found three huge bubbles in the latter part of the period 2011–2013 lasting from 66 to 106 days, with the ...

TL;DR: This work reported the synthesis of a cyano groups and K+ intercalation modified g-C3N4 (mCNN) photocatalyst with extended visible-light harvesting capacity and superior photocatalytic NRR activity (NH3 yield: 3.42 mmol g-1 h-1).
Abstract: As a metal-free nitrogen reduction reaction (NRR) photocatalyst, g-C3 N4 is available from a scalable synthesis at low cost. Importantly, it can be readily functionalized to enhance photocatalytic activities. However, the use of g-C3 N4 -based photocatalysts for the NRR has been questioned because of the elusive mechanism and the involvement of N defects. This work reports the synthesis of a g-C3 N4 photocatalyst modified with cyano groups and intercalated K+ (mCNN), possessing extended visible-light harvesting capacity and superior photocatalytic NRR activity (NH3 yield: 3.42 mmol g-1 h-1 ). Experimental and theoretical studies suggest that the -C≡N in mCNN can be regenerated through a pathway analogous to Mars van Krevelen process with the aid of the intercalated K+ . The results confirm that the regeneration of the cyano group not only enhances photocatalytic activity and sustains the catalytic cycle, but also stabilizes the photocatalyst.
