AbstractHunting and invasive species are amongst the main causes of species extinctions on oceanic islands. On the island of São Tomé hunting of introduced mammals (monkeys, civets and pigs) and endemic bird species has contrasting effects in terms of conservation. Hunting of introduced mammals may benefit native fauna and flora but pressure on endemic birds poses a threat to some species. We conducted semi-structured interviews with 119 hunters to assess the relative importance of native and introduced prey species, gathering information on personal profiles, preference and practice, and hunters’ perceptions of trends in prey populations. Eleven species were hunted, including five invasive mammals and five endemic birds of high conservation importance. Based on species hunted, techniques used and final destination of the quarry we distinguished three groups of hunters, using cluster analyses: bird, monkey and feral-pig hunters. Bird hunters were all from urban areas but most pig hunters were rural. Monkey hunters were mostly rural workers but a small proportion were from urban areas. Bird and monkey hunters were primarily motivated by commercial gains but they also hunted for enjoyment and food. In general, hunting of mammals is an opportunistic activity that, if regulated, can be sustainable and contribute to mitigating the effects of invasive species on local fauna as well contributing to local livelihoods. Given the economic drivers involved in hunting of birds, intervention to reduce or eliminate this form of hunting will require enforcement of legislation and raising awareness of the issues involved.
Index type invariants for twisted signature complexes and homotopy invariance
Authors: BENAMEUR MOULAY TAHAR , MATHAI VARGHESE 
Published: February 2014

AbstractFor a closed, oriented, odd dimensional manifold X, we define the rho invariant ρ(X,${\cal E}$,H) for the twisted odd signature operator valued in a flat hermitian vector bundle ${\cal E}$, where H = ∑ ij+1H2j+1 is an odd-degree closed differential form on X and H2j+1 is a real-valued differential form of degree 2j+1. We show that ρ(X,${\cal E}$,H) is independent of the choice of metrics on X and ${\cal E}$ and of the representative H in the cohomology class [H]. We establish some basic functorial properties of the twisted rho invariant. We express the twisted eta invariant in terms of spectral flow and the usual eta invariant. In particular, we get a simple expression for it on closed oriented 3-dimensional manifolds with a degree three flux form. A core technique used is our analogue of the Atiyah–Patodi–Singer theorem, which we establish for the twisted signature operator on a compact, oriented manifold with boundary. The homotopy invariance of the rho invariant ρ(X,${\cal E}$,H) is more delicate to establish, and is settled under further hypotheses on the fundamental group of X.
The broad view of warfare ecology: response to Marler
Authors: HANSON THOR , MACHLIS GARY E. 
Published: February 2014

SummaryA recent Comment article suggested replacing the established term warfare ecology with the name ‘military ecology’. This emerging and important sub-discipline requires an accurate, inclusive, and descriptive name. Maintaining the broad term warfare ecology reaches beyond the military to beyond to involve a much wider range of processes and stakeholders, including non-state parties and insurgencies, contractors, civilians, humanitarian and relief organizations, and reconstruction/restoration efforts. It has been adopted by practitioners from a similarly diverse range of disciplines, and used for important research that would not be included under a field limited to military studies.

SUMMARYWe investigated whether straight-line distance from residential compounds to healthcare facilities influenced mortality, the incidence of pneumonia and vaccine efficacy against pneumonia in rural Gambia. Clinical surveillance for pneumonia was conducted on 6938 children living in the catchment areas of the two largest healthcare facilities. Deaths were monitored by three-monthly home visits. Children living >5 km from the two largest healthcare facilities had a 2·78 [95% confidence interval (CI) 1·74–4·43] times higher risk of all-cause mortality compared to children living within 2 km of these facilities. The observed rate of clinical and radiological pneumonia was lower in children living >5 km from these facilities compared to those living within 2 km [rate ratios 0·65 (95% CI 0·57–0·73) and 0·74 (95% CI 0·55–0·98), respectively]. There was no association between distance and estimated pneumococcal vaccine efficacy. Geographical access to healthcare services is an important determinant of survival and pneumonia in children in rural Gambia.
The effects of using corpora on revision tasks in L2 writing with coded error feedback

Published: February 2014

AbstractThis study reports on the results of classroom research investigating the effects of corpus use in the process of revising compositions in English as a foreign language. Our primary aim was to investigate the relationship between the information extracted from corpus data and how that information actually helped in revising different types of errors in the essays. In ‘data-driven learning’, previous research has often failed to provide rigorous criteria for choosing the words or phrases suitable for correction with corpus data. By investigating the above relationship, this study aims to clarify what should be corrected by looking at corpus data. 93 undergraduate students from two universities in Tokyo wrote a short essay in 20 minutes without a dictionary, and the instructors gave coded error feedback for two lexical or grammatical errors. They deliberately selected one error which should be appropriate for checking against corpus data and one that was more likely to be corrected without using any reference resource. Three weeks later, a short hands-on instruction of the corpus query tool was given, followed by revision activities in which the participants were instructed to revise their first drafts, with or without the tool depending on the codes given to each error. 188 errors were automatically classified into three different categories (omission, addition and misformation) using natural language processing techniques. All words and phrases tagged for errors were further annotated for part-of-speech (POS) information. The results show that there was a significant difference in the accuracy rate among the three error types when the students consulted the corpus: omission and addition errors were easily identified and corrected, whereas misformation errors were low in correction accuracy. This reveals that certain errors are more suitable for checking against corpus data than others.
Faecal incontinence in older people: evaluation, treatment and new surgical techniques

Published: February 2014

SummaryFaecal incontinence is a disabling condition, with a high personal, social and economic cost. Whilst it may occur at any age, prevalence and severity of symptoms is higher among older people. There are many therapeutic options, ranging from non-invasive treatments to complex surgical techniques, with results that can be considered satisfactory in about 70% of individuals. A comprehensive study of the type of incontinence and its presentation and severity, together with consideration of the general condition of the patient and their environment, are the keys that will decide the best treatment option.
Shift beyond shift: On the erosion of the collective memory of Picard among adolescents in Lille
Authors: POOLEY TIM 
Published: February 2014

ABSTRACTThis study seeks to assess the competence in, and current perceptions of, the traditional regional ancestral variety, Picard, among school students in Lille. In the first part, dialect retention is evaluated by a series of language tests, administered in two rounds of fieldwork, the first carried out between 1995–1999 covering the whole of Lille-Métropole and the second undertaken in 2004–2005 focusing on the urban heartlands. The results show that competence in Picard, as measured by the tests, is highest among European or Metropolitan French subjects in the north-eastern part of the urban area (Roubaix-Tourcoing) despite significantly greater ethnic diversity among the school populations.In the second part of the study, the subjects’ perceptions of a range of Picard and Regional French varieties, as represented by a series of sample recordings, covering most of the picardophone areas are evaluated against a linguistic analysis of ‘picardité’ as measured by the density of Picard features in the extracts concerned. The results show a lack of correspondence between the two evaluations. Subjects’ perceptions are further clarified by their metalinguistic comments regarding the value of Picard and its place in their linguistic repertoire. As this variety is rarely if ever used in peer-to-peer exchanges, relative competence does not correlate with indicators of socialisation that proved significant with regard to other aspects of the students’ linguistic repertoire and was also found to correlate negatively with measures of regional loyalty and cultural value.The ‘real-time’ aspect of the study appears to point to some degree of ongoing erosion of awareness and confidence in recognition of the varieties concerned among the population investigated, despite some important cultural events which might have been expected to counter this trend.
Black WoodpeckerDryocopus martiushabitat selection in the Italian Alps: implications for conservation in Natura 2000 network
Authors: PIROVANO ANDREA R. , ZECCA GIOVANNI 
Published: February 2014

SummaryThe Black WoodpeckerDryocopus martiusis the largest woodpecker of the Palearctic Region and it has been recognised as a keystone species whose presence provides critical resources to secondary cavity-users in European forest ecosystems. Here we investigate cavity tree and foraging-habitat selection of Black Woodpecker in three natural parks located in the central and eastern Italian Alps and included in the Natura 2000 network. A total of 94 cavity trees were identified, showing a minimum diameter of 35 cm and a mean diameter of 51 cm. We counted 30 active nests, but only 40% were newly excavated. Silver firAbies albaand larchLarix deciduawere preferred as cavity trees, with silver fir also associated with habitat surrounding the cavity trees. Norway sprucePicea abiesand Silver fir were found to be positively associated with the surroundings of feeding sites. Logistic regression models identified the average diameter at breast height and the average tree crown height as significant predictors, positively associated with both cavity trees (AUC: 0.988) and cavity tree plots (AUC: 0.866). Also, the total volume of dead logs and the percentage of understorey cover turned out to be significant predictors of feeding sites, showing a positive and a negative association, respectively (AUC: 0.708). Cross validation of logistic regression models indicated that only cavity tree models can be considered useful tools in conservation practice. Overall, our results indicated that the Black Woodpecker behaves like an opportunist when choosing feeding sites. On the other hand, our results also indicate that the Black Woodpecker clearly behaves as a demanding species when it selects cavity trees, showing a hierarchical pattern in habitat selection and a marked preference for large trees with high crown height. We discuss the implications of our results for the conservation of the Black Woodpecker in Natura 2000 alpine sites.

SummaryThe Sahel in West Africa is a major wintering area for many western Palearctic migrants. The breeding populations of many of these have declined over the past 50 years. However, there have been few intensive field studies on migrant ecology in the Sahel and these were generally within a very restricted area. Consequently our knowledge of the distribution of species within this extensive area and the habitat associations of these species is limited. Understanding these habitat associations is essential for the effective conservation management of populations. We brought together a group of experts and consulted a wider group by email to assess the main Sahelian habitat types used by 68 African-Eurasian migrant bird species. Those species that showed strongest declines during 1970–1990 were associated with more open habitats than those newly declining during 1990–2000, when declining species were associated with habitats with more shrubs and trees. Populations of species that winter in the Sahel are generally stable or increasing now as rainfall has increased and is now near the long-term average for the Sahel. Those which use the Sahel only as a staging area are, in many cases, in rapid decline at present.
Selection of correction candidates for the normalization of Spanish user-generated content

Published: February 2014

AbstractWe present research aiming to build tools for the normalization of User-Generated Content (UGC). We argue that processing this type of text requires the revisiting of the initial steps of Natural Language Processing, since UGC (micro-blog, blog, and, generally, Web 2.0 user-generated texts) presents a number of nonstandard communicative and linguistic characteristics – often closer to oral and colloquial language than to edited text. We present a corpus of UGC text in Spanish from three different sources: Twitter, consumer reviews, and blogs, and describe its main characteristics. We motivate the need for UGC text normalization by analyzing the problems found when processing this type of text through a conventional language processing pipeline, particularly in the tasks of lemmatization and morphosyntactic tagging. Our aim with this paper is to seize the power of already existing spell and grammar correction engines and endow them with automatic normalization capabilities in order to pave the way for the application of standard Natural Language Processing tools to typical UGC text. Particularly, we propose a strategy for automatically normalizing UGC by adding a module on top of a pre-existing spell-checker that selects the most plausible correction from an unranked list of candidates provided by the spell-checker. To build this selector module we train four language models, each one containing a different type of linguistic information in a trade-off with its generalization capabilities. Our experiments show that the models trained on truecase and lowercase word forms are more discriminative than the others at selecting the best candidate. We have also experimented with a parametrized combination of the models by both optimizing directly on the selection task and doing a linear interpolation of the models. The resulting parametrized combinations obtain results close to the best performing model but do not improve on those results, as measured on the test set. The precision of the selector module in ranking number one the expected correction proposal on the test corpora reaches 82.5% for Twitter text (baseline 57%) and 88% for non-Twitter text (baseline 64%).
MaltOptimizer: Fast and effective parser optimization
Authors: BALLESTEROS MIGUEL , NIVRE JOAKIM 
Published: February 2014

AbstractStatistical parsers often require careful parameter tuning and feature selection. This is a nontrivial task for application developers who are not interested in parsing for its own sake, and it can be time-consuming even for experienced researchers. In this paper we present MaltOptimizer, a tool developed to automatically explore parameters and features for MaltParser, a transition-based dependency parsing system that can be used to train parser's given treebank data. MaltParser provides a wide range of parameters for optimization, including nine different parsing algorithms, an expressive feature specification language that can be used to define arbitrarily rich feature models, and two machine learning libraries, each with their own parameters. MaltOptimizer is an interactive system that performs parser optimization in three stages. First, it performs an analysis of the training set in order to select a suitable starting point for optimization. Second, it selects the best parsing algorithm and tunes the parameters of this algorithm. Finally, it performs feature selection and tunes machine learning parameters. Experiments on a wide range of data sets show that MaltOptimizer quickly produces models that consistently outperform default settings and often approach the accuracy achieved through careful manual optimization.
Simple and Complex Rule Induction Performance in Young and Older Adults: Contribution of Episodic Memory and Working Memory

Published: February 2014

AbstractThis study tested the hypothesis that part of the age-related decline in performance on executive function tasks is due to a decline in episodic memory. For this, we developed a rule induction task in which we manipulated the involvement of episodic memory and executive control processes; age effects and neuropsychological predictors of task performance were investigated. Twenty-six younger (mean age, 24.0; range, 19–35 years) and 27 community-dwelling older adults (mean age, 67.5; range, 50–91 years) participated. The neuropsychological predictors consisted of the performance on tests of episodic memory, working memory, switching, inhibition and flexibility. Performance of the older adults was worse for the learning and memorization of simple rules, as well as for the more demanding executive control condition requiring the manipulation of informational content. Episodic memory was the only predictor of performance on the simple learning and memorization task condition whereas an increase in rule induction complexity additionally engaged working memory processes. Together, these findings indicate that part of the age-related decline on rule induction tests may be the result of a decline in episodic memory. Further studies are needed that examine the role of episodic memory in other executive function tasks in aging. (JINS, 2014, 20, 1–9)

AbstractReduced IQ, learning difficulties and poor school performance have been reported in small-for-gestational-age (SGA) subjects. However, few studies include a comprehensive neuropsychological assessment. Our aim was to study neuropsychological functioning in young adults born SGA at term. A comprehensive neuropsychological test battery was administered to 58 SGA subjects (birth weight <10th centile) born at term, and 81 term non-SGA controls (birth weight ≥10th centile). The SGA group obtained significantly (p< .01) lower scores on the attention, executive and memory domains compared to non-SGA controls and showed higher risk of obtaining scores below −1.5SDon the memory domain (odds ratio = 13.3, 95% confidence interval: 1.57, 112.47). At a subtest level, the SGA group obtained lower scores on most neuropsychological tests, with significant differences on 6 of 46 measures: the Trail Making Test 3 (letter sequencing), the Wechsler Memory Scale mental control and the auditory immediate memory scale, the Design Fluency, the Stroop 3 (inhibition) and the Visual Motor Integration (VMI) motor coordination subtest. Young adults born SGA score more poorly on neuropsychological tests compared with non-SGA controls. Differences were modest, with more significant differences in the memory domain.

Published: February 2014

AbstractObjective:Although hospice agencies are required to provide informal caregivers (family or friends of the patient) with formal bereavement support when their loved one passes, most bereavement interventions lack standardization and remain untested. We employed the Dual Processing Model of Bereavement as a theoretical framework for assessing the potential of a secret Facebook group for bereaved hospice caregivers.Method:A mixed-methods approach was utilized to analyze online communication (posts and comments) in the secret Facebook group, and self-reported outcome measures on depression and anxiety were compared pre- and post-intervention.Results:Sixteen caregivers participated in the secret Facebook group over a period of nine months. The majority of online talk was oriented to restoration, revealing abrupt and anticipated triggers that evoked feelings of loss. Caregivers also shared loss orientation through storytelling, sharing and giving advice, and encouraging others to manage the challenges of coping. Caregiver anxiety and depression were lower after the intervention.Significance of Results:This pilot study provides insight into the use of a secret Facebook group to facilitate bereavement support to caregivers. Findings highlight the promise of Facebook for hospice bereavement support. Providers and researchers are encouraged to explore the positive outcomes associated with bereavement support.
