Using Graphs to Visualise and Detect Anomalies in Access Control System Transactions

Physical Access Control Systems are commonly used to secure doors in buildings such as airports, hospitals, government buildings and offices. These systems are designed primarily to provide an authentication mechanism, but they also log each door access as a transaction in a database. Unsupervised learning techniques can be used to detect inconsistencies or anomalies in the mobility data, such as a cloned or forged Access Badge, or unusual behaviour by staff members. In this paper, we present an overview of our method of inferring directed graphs to represent a physical building network and the flows of mobility within it. We demonstrate how the graphs can be used for Visual Data Exploration, and outline how to apply algorithms based on Information Theory to the graph data in order to detect inconsistent or abnormal behaviour.

Politically sensitive encounters: Ethnography, access and the benefits of ‘hanging out’

Negotiating politically sensitive research environments requires both a careful consideration of the methods involved, and a great deal of personal resolve. In drawing upon two distinct yet comparable fieldwork experiences this paper champions the benefits of ethnographic methods in seeking to gain positionality and research legitimacy amongst those identified as future research participants. The authors explore and discuss their use of the ethnographic concept of ‘hanging out’ in politically sensitive environments when seeking to negotiate access to potentially hard to reach participants living in challenging research environments. Through an illustrative examination of their experiences in researching commemorative rituals in Palestine and mental health in a Northern Irish prison, both authors reflect upon their use of hanging out when seeking to break down barriers and gain acceptance amongst their target research participants. Their involvement in a range of activities, not directly related to the overall aims of the research project, highlight a need for qualitative researchers to adopt a flexible research design, one that embraces serendipitous or chance encounters, when seeking to gain access to hard to reach research participants or when issues of researcher legitimacy are particularly pronounced such as is the case in politically sensitive research environments.

Access and utilisation of maternity care for disabled women who experience domestic abuse: a systematic review

Background: Although disabled women are significantly more likely to experience domestic abuse during pregnancy than non-disabled women, very little is known about how maternity care access and utilisation is affected by the co-existence of disability and domestic abuse. This systematic review of the literature explored how domestic abuse impacts upon disabled women’s access to maternity services.

Methods: Eleven articles were identified through a search of six electronic databases and data were analysed to identify: the factors that facilitate or compromise access to care; the consequences of inadequate care for pregnant women’s health and wellbeing; and the effectiveness of existing strategies for improvement.

Results: Findings indicate that a mental health diagnosis, poor relationships with health professionals and environmental barriers can compromise women’s utilisation of maternity services. Domestic abuse can both compromise, and catalyse, access to services and social support is a positive factor when accessing care. Delayed and inadequate care has adverse effects on women’s physical and psychological health, however further research is required to fully explore the nature and extent of these consequences. Only one study identified strategies currently being used to improve access to services for disabled women experiencing abuse.

Conclusions: Based upon the barriers and facilitators identified within the review, we suggest that future strategies for improvement should focus on: understanding women’s reasons for accessing care; fostering positive relationships; being women-centred; promoting environmental accessibility; and improving the strength of the evidence base.

Doing Focus Groups and Interviews with Recent Migrants to Northern Ireland: A Dynamic Interplay of Ethics, Language and Access

This case describes a qualitative social science research project that was conducted in 2009 and that examined the experiences of recent migrants to Northern Ireland. While background to the research and key findings are presented, the topic forms a backdrop to the case. The following aspects of the study are presented: the theoretical context; formulating the research question, design and methodology; key methodological issues; data collection and analysis; project dissemination; and research funding and reporting. The case pays particular attention to the needs and impact of different groups including the researcher, the funding body, the researcher’s employer and the researched. The significance of access, language and ethics to this study are examined. Finally, the way in which the research unfolded in an often-unpredictable way throughout the implementation process is highlighted in the narrative.
