This paper investigates the feasibility of using the emission intensity of low‐pressure argon and nitrogen gas discharges as the sensing mechanism for a microwave electric field optical sensor probe in microwave resonant cavities. The emission is coupled to a photodiode for detection through an optical fibre due to the difficulty in using conventional optoelectronic devices in close proximity to microwave cavities. The discharge emission intensity is monitored at a range of different input powers to the cavity. The proposed designs for the electric field sensing probe are also included.

The purpose of this paper is to provide a detailed review of radiation dosimetry techniques based on optical fibre dosimeters. It presents a comprehensive bibliography of the current research activities in the area.

A range of published work on optical fibre radiation dosimeters are presented, with the merits and limitations discussed. Each radiation dosimetry technique is discussed in turn, providing examples of dosimeters using such techniques reviewed. The main focus is on gamma radiation although other radiation dosimeters are considered.

This paper provides information on the wide range of research activity into radiation dosimeters. The dose ranges of these dosimeters are presented, along with the advantages and disadvantages of different dosimetry techniques.

A comprehensive review of published research in the area of solid radiation dosimetry is presented in this paper. It provides an individual with a review of the various techniques used and most recent research in that field.

F.A. Hayek’s famous critique of the socialist planned economy turned on the role of information in markets. In competitive markets, decision-making is decentralized and relies on locally available market signals. Decision-makers do not have to be omniscient or predict the future; they simply have to focus on market prices. By contrast, socialist planners face a much more demanding situation where they have to acquire and process vast amounts of information in a centralized fashion. The author revisits Hayek’s early work in light of the contemporary revolution in information technology, using recent research on organizational decision-making. The author argues that a great deal of market information is produced by public and private institutions, and includes much more than market prices. The boundary between tacit knowledge and formalized knowledge changes as IT enables the spread of the latter. Furthermore, the growing “knowledge economy” underscores the importance of intellectual property, and the legal institutions that support it. Overall, some of Hayek’s early insights hold up well while others need updating.

Suicide and suicide-related incidents have increased within women’s prisons in the UK. This paper aims to synthesise the findings of qualitative literature, to gain a deeper understanding of the how women and staff in English prisons experience and explain the causes of their suicidal behaviours.

A systematic search of five electronic databases, namely, MEDLINE, APA Psychological Information Database (Psycinfo), Cumulative Index to Nursing and Allied Health Literature (with full text – CINAHL), Psychology and Behavioural Sciences Collection and APA PsycArticles, was completed in January 2023. This study’s search strategy returned 1,714 articles, 7 of which were included for review. To identify relevant themes within the data, Thomas and Harden’s (2008) framework was applied. Quality appraisal was conducted by using Joanna Briggs’ Institute Checklist for Qualitative Research (Joanna Briggs Institute, 2021).

Four themes were determined, which describe the causes of suicidal behaviours in women’s prisons in England; mental health and trauma, lack of support from services and staff, contact with family and self-harm as a coping strategy. Important sub-themes were also identified including the prison environment and poor relationships with staff.

Further qualitative research is needed, however, the findings suggest greater support is required to aid positive mental health, including the provision of trauma informed coping strategies and improved staff training.

To the best of the authors knowledge, this is the first systematic review conducted on the factors contributing to women’s suicide in English prisons using qualitative literature.

Teamwork is essential for patient safety as highly functioning teams make fewer errors. In high acuity academic medical centers, care delivery is complex and ever-changing, creating a high-risk environment for safety concerns. These intricate settings demand a collaborative approach to care delivery, where structured methods of teamwork and communication are engrained in day-to-day practice. With teamwork being a critical component of patient safety and communication failures likened to preventable medical errors, hospitals are looking to bolster leadership training and improve team dynamics. TeamSTEPPS is a proven method shown to enhance teamwork, communication, leadership, and patient satisfaction. TeamSTEPPS provides an evidence-based framework to optimize patient outcomes by improving communication and teamwork skills among healthcare professionals. Current literature on teamwork and communication demonstrates that nurse practitioners are uniquely positioned to improve team performance through the use of the TeamSTEPPS framework.

Digital systems for independent aging, support and care are not being adopted as hoped. The purpose of this paper is to examine the results of three studies to derive key factors during the development and engineering process of care and support systems for older people that can impact acceptance and uptake to provide support to future projects.

The paper analyzed the results of three qualitative studies, including two detailed case studies and a further study with 35 participants, to derive key factors. Methods for deriving factors are based on thematic analysis to identify common factors across cases and participants.

The findings point to a broad set of interconnected factors that give developers of these types of systems specific recommendations. These highlight what makes these projects complex and identify implications for the development process. Furthermore, they show way the needed user-centered and iterative methods may be in conflict with funding processes.

While others have reported on single projects or looked at acceptance, these studies were the first to explore aspects of the development process that may contribute to the lack of success to date of these types of systems. The results here support more successful outcomes in the future, both by helping people involved in the development of these systems to avoid some of the issues others face and providing input to improve the performance of the engineering process.

The purpose of this paper is to highlight the neglect of girls in care who come into conflict with the law, arguing that a gender-neutral approach in this area risks further marginalising an already vulnerable population.

A critical review of the literature and current policy climate is undertaken to explore what is known about the experiences of females in the justice system, as well as knowledge gaps.

Evidence on the prevalence and nature of offending by girls in care is limited. However, as looked after children, girls may be more likely to have their own behaviour unnecessarily criminalised. Whilst females and males share some prior experiences of victimisation and trauma, girls also have distinct needs and may be assessed and managed by state care and control systems in very different ways.

The paper is not based on primary research and does not present a systematic review of the literature.

The need to listen to girls and young women, and a far greater recognition of backgrounds of trauma must underpin future policy and practice. Diversion from the formal criminal justice system wherever possible is also a key goal to aspire to.

This paper focuses on the specific experiences of females. It calls for a gender-sensitive, trauma-informed approach to working with girls and women from the care system who come into conflict with the law, and questions the value of criminalising those whom the state previously deemed to be in need of welfare and support.

Health scientists and urban planners have long been interested in the influence that the built environment has on the physical activities in which we engage, the environmental hazards we face, the kinds of amenities we enjoy, and the resulting impacts on our health. However, it is widely recognized that the extent of this influence, and the specific cause-and-effect relationships that exist, are still relatively unclear. Recent reviews highlight the need for more individual-level data on daily activities (especially physical activity) over long periods of time linked spatially to real-world characteristics of the built environment in diverse settings, along with a wide range of personal mediating variables. While capturing objective data on the built environment has benefited from wide-scale availability of detailed land use and transport network databases, the same cannot be said of human activity. A more diverse history of data collection methods exists for such activity and continues to evolve owing to a variety of quickly emerging wearable sensor technologies. At present, no “gold standard” method has emerged for assessing physical activity type and intensity under the real-world conditions of the built environment; in fact, most methods have barely been tested outside of the laboratory, and those that have tend to experience significant drops in accuracy and reliability. This paper provides a review of these diverse methods and emerging technologies, including biochemical, self-report, direct observation, passive motion detection, and integrated approaches. Based on this review and current needs, an integrated three-tiered methodology is proposed, including: (1) passive location tracking (e.g., using global positioning systems); (2) passive motion/biometric tracking (e.g., using accelerometers); and (3) limited self-reporting (e.g., using prompted recall diaries). Key development issues are highlighted, including the need for proper validation and automated activity-detection algorithms. The paper ends with a look at some of the key lessons learned and new opportunities that have emerged at the crossroads of urban studies and health sciences.

We do have a vision for a world in which people can walk to shops, school, friends' homes, or transit stations; in which they can mingle with their neighbors and admire trees, plants, and waterways; in which the air and water are clean; and in which there are parks and play areas for children, gathering spots for teens and the elderly, and convenient work and recreation places for the rest of us.

The purposes of this qualitative study were to determine the contribution of 4-H experiences to leadership life skill development of college-level 4-H alumni and to determine the effect of those skills on collegiate alumni’s desire to continue involvement in 4-H. The research methods included semi-structured interviews. Major findings of the study noted that the interviewees’ 4-H experiences positively contributed to leadership life skill development, closely following the pattern of the four essential elements which serve as the foundation of 4-H programming. Also identified was a strong desire of college-level 4-H alumni to continue their participation with 4-H. Recommendations include specifically targeting this generation of alumni for greater utilization because of their strong desire to stay connected.
