Published: April 2016

Recreational fishing, a popular leisure activity, can potentially support conservation of species and provide socio-economic benefits to local economies. Nonetheless, there are ecological concerns regarding this pastime, especially in developing economies such as India where little information is available concerning impacts on fish populations. An online survey targeting recreational anglers practicing catch-and-release (C&R) in India (n=200) revealed 25 states/union territories as prime angling locations, with Mahseer (Tor spp.) constituting the main target species group (53%). Angling season (28%) and pristine river surroundings (14%) were stated as major factors important for angling, while overfishing (31%) and the use of illegal fishing techniques were highlighted as chief threats to fish species. Respondents were in favour of strictly adhering to C&R guidelines (23%), controlling illegal fishing techniques and pollution (18%) and spreading awareness and education among local stakeholders (18%) to protect fish. Over 75% of respondents were also willing to contribute both their time and money to conservation initiatives focusing on key sport fish. With anglers targeting multiple fishing locations throughout India, there is a need for consistent governance structures and policy instruments to support the development of sustainable recreational fisheries while minimising conflict with other stakeholder groups. The impacts of C&R fisheries interactions on individuals and populations (especially for threatened species) need to be studied in the Indian context. Direct participation by recreational anglers in C&R research could strengthen broader conservation and management initiatives throughout the country by increasing stewardship.

Authors: Adarsh C. K. , Nameer P. O. 
Published: April 2016

A preliminary study was conducted to document spider diversity in Chinnar Wildlife Sanctuary, Idukki District, Kerala State in southern India. The study was conducted from October to November 2012. A total of 101 species of spiders belonging to 65 genera from 29 families were identified from the sanctuary. This accounted for 6.98% of Indian spider species, 17.81% of Indian spider genera and 48.33% of the spider families of India. The dominant families were Lycosidae (11 species) and Araneidae (10). Two endemic genera of Indian spiders such as Annandaliella and Neoheterophrictus were found at Chinnar, each representing one species each, and belonging to the family Theraphosidae. A guild structure analysis of the spiders revealed seven feeding guilds such as orb weavers, stalkers, ground runners, foliage runners, sheet web builders, space web builders and ambushers.
How Crossover Speeds up Building Block Assembly in Genetic Algorithms
Authors: Sudholt Dirk 
Published: April 2016

We reinvestigate a fundamental question: How effective is crossover in genetic algorithms in combining building blocks of good solutions? Although this has been discussed controversially for decades, we are still lacking a rigorous and intuitive answer. We provide such answers for royal road functions and OneMax, where every bit is a building block. For the latter, we show that using crossover makes every ([Formula: see text]+[Formula: see text]) genetic algorithm at least twice as fast as the fastest evolutionary algorithm using only standard bit mutation, up to small-order terms and for moderate [Formula: see text] and [Formula: see text]. Crossover is beneficial because it can capitalize on mutations that have both beneficial and disruptive effects on building blocks: crossover is able to repair the disruptive effects of mutation in later generations. Compared to mutation-based evolutionary algorithms, this makes multibit mutations more useful. Introducing crossover changes the optimal mutation rate on OneMax from [Formula: see text] to [Formula: see text]. This holds both for uniform crossover and k-point crossover. Experiments and statistical tests confirm that our findings apply to a broad class of building block functions.
Open Issues in Evolutionary Robotics

One of the long-term goals in evolutionary robotics is to be able to automatically synthesize controllers for real autonomous robots based only on a task specification. While a number of studies have shown the applicability of evolutionary robotics techniques for the synthesis of behavioral control, researchers have consistently been faced with a number of issues preventing the widespread adoption of evolutionary robotics for engineering purposes. In this article, we review and discuss the open issues in evolutionary robotics. First, we analyze the benefits and challenges of simulation-based evolution and subsequent deployment of controllers versus evolution on real robotic hardware. Second, we discuss specific evolutionary computation issues that have plagued evolutionary robotics: (1) the bootstrap problem, (2) deception, and (3) the role of genomic encoding and genotype-phenotype mapping in the evolution of controllers for complex tasks. Finally, we address the absence of standard research practices in the field. We also discuss promising avenues of research. Our underlying motivation is the reduction of the current gap between evolutionary robotics and mainstream robotics, and the establishment of evolutionary robotics as a canonical approach for the engineering of autonomous robots.

There is little work investigating the relationship between environmental changes and associated hippocampal effects on animal homing. We took advantage of previous studies in which wild, non-migratory mountain chickadees spent six months in captivity prior to being released. Over the following three years, 45.8% of the birds were resighted, and in all cases birds were identified less than 300 m from their initial capture locations at their respective elevation, despite previous studies documentingca30% captivity-related reduction of the hippocampus. Reproductive success of birds that spent six months in captivity did not differ from control birds that did not experience captivity. Our findings suggest that chickadees are highly site faithful and can return to their original capture location after spending time in captivity. Our results also have important implications for animal welfare practices as birds held in captivity bred successfully and may not need to be sacrificed following captivity.
School staff perceptions of factors influencing participation in a Whole-of-School initiative in an Indigenous community
Authors: Kulinna Pamela Hodges 
Published: April 2016

Objectives: The purpose of this study was to investigate teachers’ perspectives on factors influencing their involvement in a Whole-of-School initiative. Methods: A survey was administered to participating teachers/school personnel ( N = 81) and 30 of the teachers/school personnel also participated in mostly individual interviews. The survey was informed by Lohrmann’s Ecological Model of Coordinated School Health Programs focusing on individual, interpersonal, community, organisation and policy factors. Category mean values were calculated for the survey data (along with t tests to explore differences by participant role in the schools), and interview data were analysed via analytic induction using several trustworthiness measures. Findings: Findings revealed that all survey categories ranked 3.5 or higher on a 5-point scale and there were significant differences by participant role. Interview data provided specific examples of each of the school health ecology factors. Conclusion: Results provide support for the model Whole-of-School programme efforts, insights into teacher and school personnel involvement and resistance to a school health change initiative. The project may serve as a model for other schools/districts interested in Whole-of-School health programming. The transformation that took place is especially important in this Indigenous community with significant health concerns.

Published: April 2016

Objective We investigated implicit communication strategies for anticipatory information sharing during team performance of tasks with varying degrees of complexity. We compared the strategies used by teams with the highest level of performance to those used by the lowest-performing teams to evaluate the frequency and methods of communications used as a function of task structure. Background High-performing teams share information by anticipating the needs of their teammates rather than explicitly requesting the exchange of information. As the complexity of a task increases to involve more interdependence among teammates, the impact of coordination on team performance also increases. This observation motivated us to conduct a study of anticipatory information sharing as a function of task complexity. Method We conducted an experiment in which 13 teams of four people performed collaborative search-and-deliver tasks with varying degrees of complexity in a simulation environment. We elaborated upon prior characterizations of communication as implicit versus explicit by dividing implicit communication into two subtypes: (a) deliberative/goal information and (b) reactive status updates. We then characterized relationships between task structure, implicit communication, and team performance. Results We found that the five teams with the fastest task completion times and lowest idle times exhibited higher rates of deliberative communication versus reactive communication during high-complexity tasks compared with the five teams with the slowest completion times and longest idle times ( p = .039). Conclusion Teams in which members proactively communicated information about their next goal to teammates exhibited improved team performance. Application The findings from our work can inform the design of communication strategies for team training to improve performance of complex tasks.
Considering the Elements that Inform Perceived Peer Deviance
Authors: McGloin Jean Marie , Thomas Kyle J. 
Published: April 2016

Objectives: To consider, at a conceptual level, the factors that inform perceptions of peer deviance and subsequently, at an empirical level, the extent to which survey information from high school students confirms whether these elements shape perceptions of friends’ drinking. This study also offers an alternative way to document projection bias. Methods: 249 public high school students completed a survey about what factors inform their perceptions of friends’ drinking behavior. Subjects also responded to several vignettes in order to assess their general tendency to engage in projection. Results: Subjects rely on both observed behavior and various forms of communication when forming perceptions of friends’ drinking, though there is notable variation across these elements. When using hypothetical vignettes, results suggest projection bias is significantly diminished as subjects are provided with more information about a hypothetical peer. Conclusions: Adolescents appear to rely on a wide range of information when forming perceptions about friends’ drinking behavior. Although we did document a tendency to engage in projection when subjects had minimal information about a peer, the fragility of this tendency questions whether perceptual measures are inherently contaminated.

Published: April 2016

Objectives: There were two aims to this study: firstly, to identify family subtypes of Singaporean youth offenders based on eight family variables. Secondly, the associations of these family subtypes with youth offending outcomes were tested. Methods: With a sample of 3,744 youth, a latent class analysis was first conducted based on eight family variables. Multivariate analyses and a Cox regression were subsequently performed to analyze the associations of the family classes with age at first arrest, age at first charge, and recidivism. Results: A three-class solution was found to have the best fit to the data: (1) intact functioning families had little family risk; (2) families with criminality had higher probabilities of family criminality, of drug/alcohol abuse, and of being nonintact; and (3) poorly managed families received the poorest parenting and were more likely to be nonintact. Youth offenders from the latter two classes were arrested and charged at younger ages. Additionally, they reoffended at a quicker rate. Conclusions: Family backgrounds matter for youth offending outcomes. Interventions have to be multifaceted and targeted at the family in order to mitigate the risk of young offenders from developing into pathological adult criminals.
The Murals of La Victoria
Authors: Cortés Alexis 
Published: April 2016

Muralism is one of the most striking expressions of one of Chile’s most emblematic working-class neighborhoods, La Victoria, which is known for the land takeover in which it originated and its resistance to the military dictatorship. Muralism served as the physical carrier of messages of resistance during the dictatorship and later consolidated an imaginary of political condemnation and venting in the face of repression. With democracy, muralism has made the memory of the neighborhood graphic, propitiated a dialogue between the experience of the land occupation and the dictatorship, and generated a discourse that, emerging from the popular, continues to confront the mechanisms of forgetting circulated by the official truths imposed by the compromised democratic transition. El muralismo es una de las expresiones más propias de uno de los barrios populares más emblemáticos de Chile: La Victoria, conocida por la toma que le dio origen y por su resistencia a la dictadura militar. El muralismo cumplió la función de ser el soporte físico de mensajes de resistencia durante la dictadura, consolidando posteriormente un imaginario de denuncia política y de desahogo frente a la represión. Con la democracia, el muralismo ha tenido la función de hacer gráfica la memoria de la población, propiciando un diálogo entre la experiencia de la toma y de la dictadura, generándose una discursividad que, desde lo popular, continúa enfrentando los dispositivos de desmemoria accionados por las verdades oficiales impuestas por la transición democrática pactada.

Published: April 2016

Objective We aimed to assess the medium to long-term results of echocardiographic follow-up of perimembranous and muscular ventricular septal defect closure with various Amplatzer devices. Methods We successfully closed ventricular septal defects percutaneously in 45/49 patients. There were 35 perimembranous and 10 muscular ventricular septal defects. The median age and weight was 8.50 years (range 2–36.70 years) and 24 kg (range 10–106 kg), respectively. The median size of the ventricular septal defect was 7 mm (range 3–14 mm) on transthoracic echocardiography, 6 mm (range 4–15 mm) on transesophageal echocardiography, and 6 mm (range 3–14 mm) on left ventricular angiography. The median pulmonary-to-systemic blood flow ratio was 1.40 (range 1.0–3.0). Results In the 49 attempted cases, the procedure was successful in 45, with a success rate of 91.84%. At a mean follow-up of 54.50 months, echocardiography showed complete closure in 41 (91%) patients and 4 (9%) had a tiny (1–2 mm) residual defect. New-onset aortic regurgitation was seen in 6 (13.3%) patients at 54.50 months, but it was mild in nature. Tricuspid valve regurgitation was observed in 13 (29%) patients at 54.50 follow-up, of whom 10 (22%) had mild and 3 (7%) had moderate regurgitation. Conclusion Transcatheter closure of perimembranous and muscular ventricular septal defects is effective, however, these patients need to be followed up regularly to detect device-related problems, specifically, aortic and tricuspid valve regurgitation.

Objective: To evaluate late outcomes after posterior mitral valve (MV) annulus double-suture annuloplasty for degenerative (non-ischaemic) MV insufficiency. Design: Between 2005 and 2011, 138 patients underwent MV repair using posterior MV double-suture annuloplasty and an additional 105 patients underwent tricuspid valve repair. The study protocol included operative mortality, reoperation rate and reasons, as well as echocardiographic parameters at pre- and postoperative and follow-up periods (2-9 years). Results: In-hospital mortality was 2/138 (1.45%). Early post operation, no regurgitation was noted in 74/136 (54.4%) patients, Io regurgitation was observed in 55/136 (40.4%), IIo was observed in 6/136 (4.4%) and IIIo was observed in 1/136 (0.7%); during late follow-up (from 2 to 9 years), no regurgitation was observed in 21.6% patients, Io was observed in 58%, IIo was observed in 17% and IIIo was observed in 3.4%. The mean preoperative anterolateral diameter of the MV annulus was 39.02±4.97 mm and, at late follow-up, it was 27.66±3.94 mm (p=0.000); at these same time points, left ventricular end-diastolic diameter (LVEDD) was 55.74±7.29 mm and 49.17±6.01 mm (p=0.000), respectively, and the left ventricular ejection fraction (LVEF) was 53.08±8.93% and 50.92±6.78%, respectively (p=0.007). Conclusions: This study demonstrates suture annuloplasty to be an effective treatment up to 9 years for degenerative mitral valve disease. This technique enables preservation of the posterior mitral valve annulus diameter with stable long-term (up to 9 years) reduction, a competent (no regurgitation/⩽IIo regurgitation) MV in 96.6% of cases and positive left ventricular (LV) remodelling.

Published: April 2016

Objectives: A meta-analysis and systematic review was conducted to investigate the potential effects of repetitive transcranial magnetic stimulation on dysphagia in patients with stroke, including different parameters of frequency and stimulation site. Methods: PubMed, Embase, MEDLINE databases and the Cochrane Library, were searched for randomized controlled studies of repetitive transcranial magnetic stimulation treatment of dysphagia published before March 2016. Results: Six clinical randomized controlled studies of a total of 163 stroke patients were included in this meta-analysis. A significant effect size of 1.24 was found for dysphagic outcome (mean effect size, 1.24; 95% confidence interval (CI), 0.67–1.81). A subgroup analysis based on frequency showed that the clinical scores were significantly improved in dysphagic patients with low frequency repetitive transcranial magnetic stimulation treatment ( P < 0.05) as well as high frequency repetitive transcranial magnetic stimulation treatment ( P < 0.05). A stimulation site stratified subgroup analysis implied significant changes in stroke patients with dysphagia for the unaffected hemisphere ( P < 0.05) and the bilateral hemisphere stimulation ( P < 0.05), but not for the affected hemisphere ( P > 0.05). The analysis of the follow-up data shows that patients in the repetitive transcranial magnetic stimulation groups still maintained the therapeutic benefit of repetitive transcranial magnetic stimulation four weeks after the last session of repetitive transcranial magnetic stimulation therapy ( P < 0.05). Conclusion: This meta-analysis indicates that repetitive transcranial magnetic stimulation has a positive effect on dysphagia after stroke. Compared with low-frequency repetitive transcranial magnetic stimulation, high-frequency repetitive transcranial magnetic stimulation may be more beneficial to the patients. This meta-analysis also supports that repetitive transcranial magnetic stimulation on an unaffected – or bilateral – hemisphere has a significant therapeutic effect on dysphagia.

Published: April 2016

Background Headache is common in patients with Moyanoya angiopathy (MMA), but usually underestimated in its management and not well characterized. Methods A validated self-administered headache screening questionnaire and a telephone interview were used in order to investigate headache characteristics, frequency and pain intensity in a large cohort of 55 German patients with MMA. Results Thirty-seven patients (67.3%) had suffered from headache in the past year. Headache intensity was rated 3.2 ± 1.3 on a verbal rating scale from 0 to 10. Seventeen patients (47.9%) reported migraine-like headache, 10 patients (27.0%) reported tension type-like headache and 10 patients (27.0%) had a combination of both. The majority of patients with migraine-like headache ( n = 10, 58.8%) described migrainous aura. Headache frequency and intensity improved significantly after revascularization surgery; however, nine patients developed new-onset headache postoperatively. Conclusion Headache is very common in MMA, often with a migraine-like phenotype. Tension type-like headache was also found in 27% of patients, which is a new finding that has not been reported before.
