Maternal emotion coaching, adolescent anger regulation, and siblings' externalizing symptoms.

BACKGROUND Increases in externalizing behaviors during the transition to adolescence may put children at risk for developing mental disorders and related problems. Although children's ability to regulate their emotions appears to be a key factor influencing risk for maladjustment, emotion processes during adolescence remain understudied. In this longitudinal study, we examined a multi-level mediational model in which emotion coaching by parents was posited to influence the ability of adolescents to regulate their emotions, which in turn influences their expression of problem behaviors. METHODS We recruited a representative community sample of 244 families with biological sibling pairs comprising a child in late elementary school and a child in middle school. Maternal meta-emotion interviews were coded for mother emotion coaching and adolescent difficulty with anger. Mothers also completed questionnaires on adolescent irritability. Ratings of adolescent problem behaviors were obtained from mother and teacher questionnaires completed at two time points. Using structural equation modeling, constructs were partitioned into components across older and younger siblings to examine shared and nonshared variance and contextual effects. RESULTS Cross-sectional data indicated that mothers' emotion coaching of anger was related to better anger regulation in adolescent siblings, which was, in turn related to less externalizing behavior. Although support for mediational effects was limited in the longitudinal data, both older and younger siblings' difficulties in regulating anger predicted adolescent externalizing behavior three years later. Additional longitudinal predictors of externalizing behavior were observed for younger siblings. In particular, emotion coaching of anger by mothers was associated with decreased externalizing behavior, while conversely, older siblings' externalizing behavior was associated with increased externalizing behavior in the younger siblings over time. CONCLUSIONS The findings highlight the importance of considering family emotion processes in understanding adolescent problem behavior. Both maternal emotion coaching of adolescent anger and adolescent difficulty in regulating anger influenced adolescent externalizing behavior. Emotion coaching interventions seem worthy of consideration for enhancing the impact of prevention and intervention programs targeting youth externalizing behaviors.
Political Connections and Merger Performance: Evidence from Chinese Market

In this paper, we examine the role of political connections by analyzing the short-and long-term performance of Chinese state owned enterprise (SOE) acquirers relative to private owned enterprise (POE) from 1994 to 2008. The empirical result shows that 1) SOE acquirers outperform the POE acquirer both in terms of long-run stock and operating performance; 2) announcement effect of POE acquirer taking over SOE target is significantly positive; 3) SOE-related mergers have superior stock performance during hot political periods. Moreover, our evidence shows that SOE acquirers have higher operating margin but lower asset turnover, suggesting the outperformance of SOE acquirers are due to their superior profitable business instead of efficient usage of asset. Compared to POE acquirers, SOE acquirers also have lower leverage ratio, higher quick ratio as well as more asset value. These finding suggest that the value of SOEs acquisitions is derived from government financial and policy support because of their political connections.
A tensor voting approach to dark spot detection in RADARSAT-1 intensity imagery

This paper presents a tensor voting approach to automated detection of dark spots in RADARSAT-1 ScanSAR Narrow Beam mode images. First, a thresholding algorithm that well maximizes the ratio of between-class variance to within-class variance is used to detect potential dark spot candidates. Next, a tensor voting framework integrated with sparse and dense ball votings is carried out to suppress noise while maintaining dark spots. Then, a saliency map that reflects the probability of a pixel being located within a dark spot is generated using the saliencies of ball tensors. Finally, a segmentation method is applied to ascertain dark spots based on the saliency map. The proposed approach has been tested on a set of RADARSAT-1 ScanSAR Narrow Beam intensity images. Quantitative evaluations demonstrate that the proposed approach achieves an average commission error, omission error, and quality of 0.003, 0.037, and 0.956, respectively, for detecting dark spots in SAR intensity imagery.
Prolonged Perioperative Low-Dose Ketamine Does Not Improve Short and Long-term Outcomes After Pediatric Idiopathic Scoliosis Surgery

Study Design. A randomized, double-blind, placebo-controlled study, with a six-month follow-up period. Objectives. The aim of this study was to test the hypothesis that a 72-hour dose of subanesthetic ketamine in this surgical procedure reduces postoperative morphine use and to assess whether there are fewer adverse effects, if postoperative recovery is faster, if there is less peri-incisional hyperalgesia, or if there is lower incidence of persistent postsurgical pain. Summary of Background Data. Tissue injury and high opioid requirements following posterior spinal fusion surgery produce central sensitization, which can in turn be associated with hyperalgesia and chronic pain. Clinical trials involving this type of procedure using subanesthetic ketamine doses have assessed pain and morphine requirements with contradictory results. The effects of prolonged subanesthetic ketamine doses on postoperative recovery, mechanical hyperalgesia, and the incidence of chronic pain are unknown. Methods. A total of 48 pediatric patients between 10 and 18 years diagnosed with idiopathic scoliosis were randomized to receive perioperative low-dose ketamine or placebo for 72 hours. They received general anesthesia, intraoperative remifentanil, and morphine postoperatively (patient-controlled analgesia). We measured morphine consumption, pain at rest and during movement (coughing), undesirable effects, and sedation during morphine treatment. The onset of oral intake, ambulation, and hospital stay were recorded. The extent of the peri-incisional hyperalgesia was measured at 72 hours and pain controls were conducted postsurgery. Results. Primary endpoint results (total cumulative morphine consumption while admitted) were obtained in 44 patients. Results were 2.72 (SD 1.13) in the placebo group and 3.13 (SD 1.13) in the study group (P = 0.2903), with no significant differences. Moreover, differences were not found between the experimental group and the placebo group in the secondary endpoints analyzed. Conclusion. Our findings do not support the routine combining of prolonged subanesthetic ketamine doses with opioids in posterior fusion surgery in children with idiopathic scoliosis. Level of Evidence: 2
Using populations of human and microbial genomes for organism detection in metagenomes

Identifying causative disease agents in human patients from shotgun metagenomic sequencing (SMS) presents a powerful tool to apply when other targeted diagnostics fail. Numerous technical challenges remain, however, before SMS can move beyond the role of research tool. Accurately separating the known and unknown organism content remains difficult, particularly when SMS is applied as a last resort. The true amount of human DNA that remains in a sample after screening against the human reference genome and filtering nonbiological components left from library preparation has previously been underreported. In this study, we create the most comprehensive collection of microbial and reference-free human genetic variation available in a database optimized for efficient metagenomic search by extracting sequences from GenBank and the 1000 Genomes Project. The results reveal new human sequences found in individual Human Microbiome Project (HMP) samples. Individual samples contain up to 95% human sequence, and 4% of the individual HMP samples contain 10% or more human reads. Left unidentified, human reads can complicate and slow down further analysis and lead to inaccurately labeled microbial taxa and ultimately lead to privacy concerns as more human genome data is collected.
College Expectations for All? The Early Adult Outcomes of Low-Achieving Adolescents Who Expect to Earn a Bachelor's Degree

Critics of the college-for-all ethos argue that it encourages low-achieving adolescents to develop unrealistically high expectations. This argument posits that low-achievers waste time and money, and risk disappointment and self-recrimination, pursuing college when they are unlikely to complete it. The present study uses two national data sets—Add Health and the National Longitudinal Survey of Youth 1979—to test the proposition that expecting to earn a bachelor's degree (BA) puts low-achieving students at risk of disadvantageous early adult outcomes. Youth reported their educational expectations in high school, and their income-to-needs ratios and depressive symptoms were measured approximately a decade later. Results in both data sets suggest that the expectation of a BA was advantageous for all students, regardless of achievement level. Low-achievers who expected to earn a BA had higher educational attainment, higher income-to-needs ratios, and fewer depressive symptoms than low-achievers who did not expect to earn a BA.
Chlorthalidone Compared With Hydrochlorothiazide in Reducing Cardiovascular Events: Systematic Review and Network Meta-Analyses

Hydrochlorothiazide (HCTZ) is widely used for hypertension, and prescriptions for HCTZ outnumber those for chlorthalidone (CTDN) by >20-fold in 2 recent surveys. Some have recently expressed a preference for CTDN. However, head-to-head trials testing the effect of the 2 drugs on cardiovascular events (CVEs) are lacking. We conducted a systematic review of randomized trials in which 1 arm was based on either HCTZ or CTDN followed by 2 types of network meta-analyses, a drug-adjusted analysis and an office systolic blood pressure–adjusted analysis. Nine trials were identified: 3 based on HCTZ and 6 based on CTDN. In the drug-adjusted analysis (n=50946), the percentage of risk reduction in congestive heart failure for CTDN versus HCTZ was 23 (95% CI, 2–39; P=0.032); and in all CVEs was 21 (95% CI, 12–28; P<0.0001). In the office systolic blood pressure–adjusted analysis (n=78350), the percentage of risk reduction in CVEs for CTDN versus HCTZ was 18 (95% CI, 3–30; P=0.024). When the reduction in office systolic blood pressure was identical in the 2 arms, the risk for CVEs in HCTZ arms was 19% higher than in its nondiuretic comparator arms (P=0.021). Relative to HCTZ, the number needed to treat with CTDN to prevent 1 CVE over 5 years was 27. In conclusion, CTDN is superior to HCTZ in preventing cardiovascular events. This cannot be attributed entirely to the lesser effect of HCTZ on office systolic blood pressure but may be attributed to the pleomorphic effects of alternative medications or to the short duration of action of HCTZ.
Hierarchical Disparity Estimation with Programmable 3D Hardware

This work presents an implementation of a hierarchical disparity estimation algorithm entirely executed on programmable 3D graphics hardware. In contrast to previous hardware based implementations of computational stereo algorithms, our method calculates disparities either for rectified stereo images or uncalibrated pairs of stereo images without known epipolar geometry. We exploit features of modern graphics hardware to search for correct disparity vectors eciently. The hierarchical approach increases the speed and the robustness of the algorithm. Additionally, we use bidirectional matching to remove false matches. We observe up to 50 fps for input images with 256 ◊ 256 pixels resolution on desktop graphics cards and up to 30 fps on mobile 3D hardware.
Dynamics of ligand substitution in labile cobalt complexes resolved by ultrafast T-jump

Ligand exchange of hydrated metal complexes is common in chemical and biological systems. Using the ultrafast T-jump, we examined this process, specifically the transformation of aqua cobalt (II) complexes to their fully halogenated species. The results reveal a stepwise mechanism with time scales varying from hundreds of picoseconds to nanoseconds. The dynamics are significantly faster when the structure is retained but becomes rate-limited when the octahedral-to-tetrahedral structural change bottlenecks the transformation. Evidence is presented, from bimolecular kinetics and energetics (enthalpic and entropic), for a reaction in which the ligand assists the displacement of water molecules, with the retention of the entering ligand in the activated state. The reaction time scale deviates by one to two orders of magnitude from that of ionic diffusion, suggesting the involvement of a collisional barrier between the ion and the much larger complex.
Student Volunteering in China and Canada:Comparative Perspectives

While many of the theoretical frameworks for volunteering have been developed and empirically tested in the west, our understanding of volunteering in non-Western countries, such as China, is relatively limited. Nevertheless, in recent decades enormous efforts have been made by the Chinese government to encourage and support volunteering among its citizens, especially youth. Chinese youth are volunteering in greater numbers in response to these initiatives. Given the strongly state-led nature of volunteering in China, as opposed to the voluntary, more citizen-initiated nature of volunteering in Western societies, this paper seeks to understand the impact of these contextual differences on student volunteering. Using data from 1892 questionnaires completed by university students in China and Canada, we examine differences in their volunteering. The findings show clearly the impact of the differences in socio-political structures that are reflected in the nature of students’ volunteer participation and perceived benefits.
National Athletic Trainers' Association position statement: conservative management and prevention of ankle sprains in athletes.

OBJECTIVE To present recommendations for athletic trainers and other allied health care professionals in the conservative management and prevention of ankle sprains in athletes. BACKGROUND Because ankle sprains are a common and often disabling injury in athletes, athletic trainers and other sports health care professionals must be able to implement the most current and evidence-supported treatment strategies to ensure safe and rapid return to play. Equally important is initiating preventive measures to mitigate both first-time sprains and the chance of reinjury. Therefore, considerations for appropriate preventive measures (including taping and bracing), initial assessment, both short- and long-term management strategies, return-to-play guidelines, and recommendations for syndesmotic ankle sprains and chronic ankle instability are presented. RECOMMENDATIONS The recommendations included in this position statement are intended to provide athletic trainers and other sports health care professionals with guidelines and criteria to deliver the best health care possible for the prevention and management of ankle sprains. An endorsement as to best practice is made whenever evidence supporting the recommendation is available.
Inorganic Materials and Assembly Techniques for Flexible and Stretchable Electronics

In recent years, important progress has been made in developing design strategies, materials, and associated assembly techniques that provide empowering approaches to electronics with unconventional formats, ones that allow useful but previously hard to realize attributes of function. Notable examples of the progress made include: light weight, large area, high performance electronics, optics, and photonics; electronic and optical systems with curvilinear shapes and capacities for accommodating demanding forms of mechanical flexure; new device form factors for use in sensing and imaging; the integration of high performance electronics in 3-D with demanding nanometer design rules; functional bioresponsive electronics; and advanced hybrid materials systems for lighting, energy storage, and photovoltaic energy conversion. In this report we highlight advances that are enabling such promising capabilities in technology-specifically, the fabrication of device elements using high performance inorganic electronic materials joined with printing and transfer methods to effect their integration within functional modules. We emphasize in this review considerations of the design strategies and assembly techniques that, when taken together, circumvent limitations imposed by approaches that integrate circuit elements within compact, rigid, and essentially planar form factor devices, and provide a transformational set of capabilities for high performance flexible/stretchable electronics.
Genome update: distribution of two-component transduction systems in 250 bacterial genomes.

An additional four bacterial genomes have been deposited in GenBank (‘Candidatus Pelagibacter ubique’, Pseudomonas syringae pv. phaseolicola 1448A, ‘Psychrobacter arcticum’ and Staphylococcus haemolyticus). Furthermore, three protozoan genomes have been published (Leishmania major, Trypanosoma cruzi and Trypanosoma brucei).
Hybrid Language Segmentation for Historical Documents

English. Language segmentation, i.e. the division of a multilingual text into monolingual fragments has been addressed in the past, but its application to historical documents has been largely unexplored. We propose a method for language segmentation for multilingual historical documents. For documents that contain a mix of highand low-resource languages, we leverage the high availability of highresource language material and use unsupervised methods for the low-resource parts. We show that our method outperforms previous efforts in this field. Italiano. La segmentazione del linguaggio, la divisione di un testo multilingue in frammenti monolingue, è stata affrontata nel passato, ma la sua applicazione a documenti storici è rimasta in gran parte inesplorata. Proponiamo un metodo per la segmentazione linguistica di documenti storici multilingue. Per documenti che contengono sia lingue ad alta disponibilità di risorse che lingue sottorappresentate, utilizziamo a nostro vantaggio l’elevata disponibilità delle lingue con un’ampia gamma di risorse e impieghiamo sistemi non supervisionati per le parti che dispongono di un minor numero di risorse. Mostriamo che il nostro metodo supera gli sforzi precedenti in questo settore.
Population genomics based on low coverage sequencing: how low should we go?

Research in molecular ecology is now often based on large numbers of DNA sequence reads. Given a time and financial budget for DNA sequencing, the question arises as to how to allocate the finite number of sequence reads among three dimensions: (i) sequencing individual nucleotide positions repeatedly and achieving high confidence in the true genotype of individuals, (ii) sampling larger numbers of individuals from a population, and (iii) sampling a larger fraction of the genome. Leaving aside the question of what fraction of the genome to sample, we analyze the trade‐off between repeatedly sequencing the same nucleotide position (coverage depth) and the number of individuals in the sample. We review simple Bayesian models for allele frequencies and utilize these in the analysis of how to obtain maximal information about population genetic parameters. The models indicate that sampling larger numbers of individuals, at the expense of coverage depth per nucleotide position, provides more information about population parameters. Dividing the sequencing effort maximally among individuals and obtaining approximately one read per locus and individual (1 × coverage) yields the most information about a population. Some analyses require genetic parameters for individuals, in which case Bayesian population models also support inference from lower coverage sequence data than are required for simple likelihood models. Low coverage sequencing is not only sufficient to support inference, but it is optimal to design studies to utilize low coverage because they will yield highly accurate and precise parameter estimates based on more individuals or sites in the genome.
Free will, temptation, and self-control: We must believe in free will. We have no choice

Baumeister, Sparks, Stillman, and Vohs (2007), sketch a theory of free will as the human ability to exert self-control. Self-control can produce goal-directed behavior, which free will conceptualized as random behavior cannot. We question whether consumer psychology can shed light on the ontological question of whether free will exists. We suggest that it is more fruitful for consumer psychology to examine consumer's belief in free will. Specifically, we propose that this belief arises from customers' phenomenological experience of exercising self-control in the face of moral or inter-temporal conflicts of will. Based on extant literature in philosophy, psychology, and economics, we offer both a narrower conceptualization of the nature of self-control problems and a more general conceptualization of self-control strategies, involving not only willpower but also precommitment. We conclude with a discussion of the consequences of consumer's belief in free will.
Reliable overlay multicast with loosely coupled TCP connections

We consider the problem of architecting a reliable content delivery system across an overlay network using TCP connections as the transport primitive. We first argue that natural designs based on store-and-forward principles that tightly couple TCP connections at intermediate end-systems impose fundamental performance limitations, such as dragging down all transfer rates in the system to the rate of the slowest receiver. In contrast, the ROMA architecture we propose incorporates the use of loosely coupled TCP connections together with fast forward error correction techniques to deliver a scalable solution that better accommodates a set of heterogeneous receivers. The methods we develop establish chains of TCP connections, whose expected performance we analyze through equation-based methods. We validate our analytical findings and evaluate the performance of our ROMA architecture using a prototype implementation via extensive Internet experimentation across the PlanetLab distributed testbed.
