Segmenting broadcast news streams using lexical chains

In this paper we propose a course-grained NLP approach to text segmentation based on the analysis of lexical cohesion within text. Most work in this area has focused on the discovery of textual units that discuss subtopic structure within documents. In contrast our segmentation task requires the discovery of topical units of text i.e. distinct news stories from broadcast news programmes. Our system SeLeCT first builds a set of lexical chains, in order to model the discourse structure of the text. A boundary detector is then used to search for breaking points in this structure indicated by patterns of cohesive strength and weakness within the text. We evaluate this technique on a test set of concatenated CNN news story transcripts and compare it with an established statistical approach to segmentation called TextTiling

SeLeCT: a lexical cohesion based news story segmentation system

In this paper we compare the performance of three distinct approaches to lexical cohesion based text segmentation. Most work in this area has focused on the discovery of textual units that discuss subtopic structure within documents. In contrast our segmentation task requires the discovery of topical units of text i.e., distinct news stories from broadcast news programmes. Our approach to news story segmentation (the SeLeCT system) is based on an analysis of lexical cohesive strength between textual units using a linguistic technique called lexical chaining. We evaluate the relative performance of SeLeCT with respect to two other cohesion based segmenters: TextTiling and C99. Using a recently introduced evaluation metric WindowDiff, we contrast the segmentation accuracy of each system on both "spoken" (CNN news transcripts) and "written" (Reuters newswire) news story test sets extracted from the TDT1 corpus

UniPrime2: a web service providing easier Universal Primer design

The UniPrime2 web server is a publicly available online resource which automatically designs large sets of universal primers when given a gene reference ID or Fasta sequence input by a user. UniPrime2 works by automatically retrieving and aligning homologous sequences from GenBank, identifying regions of conservation within the alignment, and generating suitable primers that can be used to amplify variable genomic regions. In essence, UniPrime2 is a suite of publicly available software packages (Blastn, T-Coffee, GramAlign, Primer3), which reduces the laborious process of primer design, by integrating these programs into a single software pipeline. Hence, UniPrime2 differs from previous primer design web services in that all steps are automated, linked, saved and phylogenetically delimited, only requiring a single user-defined gene reference ID or input sequence. We provide an overview of the web service and wet-laboratory validation of the primers generated. The system is freely accessible at: http://uniprime.batlab.eu.

Ethically Driven and Methodologically Tailored: Setting the Agenda for Systematic Reviews in Domestic Violence and Abuse

PURPOSE: Systematic reviews have an important, and growing, role to play in the global evidence eco-system of domestic violence and abuse. Alongside substantive contributions to knowledge, such reviews stimulate debates about ethical reviewing practices and the importance of tailoring methods to the nuances of the field. This paper aims to pinpoint a set of ethical and methodological priorities to guide and enhance review practices specifically in the field of domestic abuse. METHOD: The five Pillars of the Research Integrity Framework (ethical guidelines for domestic abuse research) are used to interrogate the systematic review process. To do so, the Framework is retrospectively applied to a recently completed systematic review in domestic abuse. The review included a rapid systematic map and in-depth analysis of interventions aimed at creating or enhancing informal support and social networks for victim-survivors of abuse. RESULTS: Ethical and methodological priorities for systematic reviews in domestic abuse include (1) Safety and wellbeing: maintaining the wellbeing of researchers and stakeholders, and appraising the ethics of included studies, (2) Transparency/ accountability: transparent reporting of research funding, aims and methods together with explicit consideration of authorship of outputs, (3) Equality, human rights and social justice: developing diverse review teams/ Advisory groups, and review methods that aim to search for, and report, diverse perspectives. Considering researcher positionality/ reflexivity in the review, (4) Engagement: collaboration with non-academic stakeholders and individuals with lived experience throughout the review process, (5) Research Ethics: independent ethical scrutiny of systematic review proposals with input from researchers with expertise in systematic reviews and domestic abuse. CONCLUSION: Additional research is required to comprehensively examine the ethics of each stage of the review process. In the meantime, attention should be given to the underpinning ethical framework for our systematic review practices and the wider research infrastructure that governs reviews

Assessing victim risk in cases of violent crime

Purpose: There is a body of evidence that suggests a range of psychosocial characteristics demarcate certain adults to be at an elevated risk for victimisation. To this end, the aim of the current study was to examine consistency between one police force, and a corresponding victim support service based in England, in their assessment of level of risk faced by victims of violent crime. Methodology: This study explored matched data on 869 adult victims of violent crime gathered from these two key services in Preston, namely Lancashire Constabulary and Victim Support, from which a sub-group of comparable ‘domestic violence’ cases (n=211) were selected for further examination. Findings: Data analyses revealed methodological inconsistencies in the assessment of victimisation resulting in discrepancies for recorded levels of risk in domestic violence cases across these two agencies. Practical implications: These findings provide a compelling argument for developing a more uniformed approach to victim assessment and indicate a significant training need. Value: This paper highlights areas of good practice and forwards several recommendations for improved practice that emphasises the integration of empirical research conducted by psychologists to boost the validity and reliability of risk assessment approaches and tools used

Repeat Victimisation, Retraumatisation and Victim Vulnerability

Abstract: This study explores the contribution that traumatic experiences and psychological post-traumatic stress symptoms make to predicting subsequent revictimisation in a sample of violent crime victims. In addition, the timing of first trauma exposure was also explored. Fifty-four adult victims (27 male and 27 female) of police recorded violent crime were interviewed and their traumatic exposure history, trauma symptomology, age at first trauma exposure as well as psychological and psychosocial functioning were assessed. These victims were followed longitudinally and subsequent revictimisation between six and twelve months post index victimisation measured. A greater number of types of trauma exposure was related lower emotional stability, higher trauma symptomology and revictimisation. Those victims with childhood traumatic exposure reported more trauma symptomology exposure than those without prior exposure. The implications for law enforcement and victim services are discussed

Emergency supply of prescription-only medicines to patients by community pharmacists: a mixed methods evaluation incorporating patient, pharmacist and GP perspectives

Objective To evaluate and inform emergency supply of prescription-only medicines by community pharmacists (CPs), including how the service could form an integral component of established healthcare provision to maximise adherence. Design Mixed methods. 4 phases: prospective audit of emergency supply requests for prescribed medicines (October–November 2012 and April 2013); interviews with CPs (February–April 2013); follow-up interviews with patients (April–May 2013); interactive feedback sessions with general practice teams (October–November 2013). Setting 22 community pharmacies and 6 general practices in Northwest England. Participants 27 CPs with experience of dealing with requests for emergency supplies; 25 patients who received an emergency supply of a prescribed medicine; 58 staff at 6 general practices. Results Clinical audit in 22 pharmacies over two 4-week periods reported that 526 medicines were requested by 450 patients. Requests peaked over a bank holiday and around weekends. A significant number of supplies were made during practice opening hours. Most requests were for older patients and for medicines used in long-term conditions. Difficulty in renewing repeat medication (forgetting to order, or prescription delays) was the major reason for requests. The majority of medicines were ‘loaned’ in advance of a National Health Service (NHS) prescription. Interviews with CPs and patients indicated that continuous supply had a positive impact on medicines adherence, removing the need to access urgent care. General practice staff were surprised and concerned by the extent of emergency supply episodes. Conclusions CPs regularly provide emergency supplies to patients who run out of their repeat medication, including during practice opening hours. This may aid adherence. There is currently no feedback loop, however, to general practice. Patient care and interprofessional communication may be better served by the introduction of a formally structured and funded NHS emergency supply service from community pharmacies, with ongoing optimisation of repeat prescribing

The UN Sustainable Development Goals (SDGs): Contributions from the Humanities

It is widely agreed that achieving the United Nations Sustainable Development Goals requires the insights, knowledge and comparative perspectives of Humanities disciplines. The UNESCO Hangzhou Declaration of 2013 highlighted the importance of culture as ‘an enabler and driver of sustainable development’. Yet the Humanities have so far featured relatively little in work on the SDGs

Training Informal Supporters to Improve Responses to Victim-Survivors of Domestic Violence and Abuse: A Systematic Review

Informal supporters (friends, family, colleagues, and community members) play a crucial role in societal-wide responses to victim-survivors of domestic violence and abuse. Familial and social networks, however, report a sense of helplessness and difficulties in knowing how to respond. This mixed method systematic review examines the effectiveness, and perceived effectiveness, of training informal supporters to improve their responses to victim-survivors. A novel conceptual framework was developed to underpin the review. A systematic search of four electronic databases, specialist repositories, and websites were used to identify empirical research (in academic or gray literature). Eleven included studies examined educational interventions that aimed to improve responses from informal supporters. Quality appraisal was undertaken, and studies were judged to be "good enough" for synthesis. The studies in the review indicated that informal supporters recognized the value of training for building understanding and equipping them with the skills to respond to victim-survivors. The synthesis identified statistically significant improvements in the knowledge and attitudes of informal supporters in the immediate and short-term following training. Using a behavior change model to frame the evidence, the review found that training/educational activities prime informal supporters to respond to victim-survivors, as well as enhancing their capacity and motivation to do so. This increases the likelihood that informal supporters will take action to support victim-survivors of abuse. We don't know, however, what type of support they will provide and/or whether it would be judged to be helpful by victim-survivors
