OBJECTIVE: Jaywalking is an important cause of pedestrian-related automobile accidents. Exploring the factors that influence jaywalking behavior and suggesting appropriate improvement measures are critical for reducing automobile accidents involving pedestrians. METHODS: This study divided traffic situations into high-risk and low-risk situations. Each situation contained three visual attention cues: vehicle, traffic light, and group behavior. Based on this, the role of visual cues in guiding pedestrians' attention and influencing their decisions during jaywalking was examined...

2-Fluorodeschloroketamine (2-FDCK) is a new psychoactive substance (NPS), close to the ketamine structure. Few cases of 2-FDCK intake are described in the forensic literature, especially concerning death cases. We report here a case of self-mutilation (Case 1) and two forensic deaths linked to 2-FDCK consumption. The second case involved a man found dead in the street, having been stabbed. The third case was a man found dead following a suspected overdose and in an advanced state of putrefaction. For all three cases, biological fluids such as blood and urine were analyzed, as was hair for the two fatal cases...

BACKGROUND: Active School Travel (AST) initiatives align with the Ottawa Charter for Health Promotion, which calls for 'creating supportive environments' and 'strengthening community action.' However, their reliance on volunteers poses sustainability challenges. The main objectives of this study were to document the motivations, satisfaction, and experiences of volunteers involved in sustaining two AST initiatives in Ontario for an entire school year. METHODS: Two volunteer-led School Street initiatives in Kingston, Ontario successfully operated during pick-up and drop-off times of each school day...

Vortex rings are ubiquitous topological structures in nature. In solid magnetic systems, their formation leads to intriguing physical phenomena and potential device applications. However, realizing these topological magnetic vortex rings and manipulating their topology on demand have still been challenging. Here, we theoretically show that topological vortex rings can be created by a current pulse in a chiral magnetic nanocylinder with a trench structure. The creation process involves the formation of a vortex ring street, i...

In November 1881, the eminent physiologist and physician David Ferrier was prosecuted under the Cruelty to Animals Act 1876. The prosecution was raised by the Victoria Street Society, formerly known as the Society for the Protection of Animals Liable to Vivisection, through its activist founder, Frances Power Cobbe. This article examines the legislative context prior to Ferrier's trial, the personalities involved in the prosecution, and its course and outcome. The resultant impact, both personal, on Cobbe and Ferrier, and professional, on experimental neurophysiology, is discussed, in particular the foundation of the Association for the Advancement of Medicine by Research (AAMR) and the provision of legal support for medical practitioners subject to litigation...

In response to an increase in overdose deaths, there was a rapid scale-up of supervised consumption services (SCS), including federally sanctioned SCS and low-barrier SCS known as overdose prevention sites (OPS), in Vancouver, Canada, beginning in December 2016. However, little is known about the use of such services among adolescents and young adults (AYA) in this context. We therefore sought to characterize factors associated with the use of federally sanctioned SCS and OPS among street-involved AYA who inject drugs in Vancouver during an overdose crisis...

OBJECTIVE: This study examines the impacts of urbanisation-induced displacement on rural older villagers and the issues of rebuilding ageing in place in Suzhou Municipality in China's Jiangsu Province. METHODS: The study employed a qualitative research method involving three measures of data collection, including 20 older-adult interviews, 14 key informant interviews (with street and community administrators, managers of service companies, managers of nursing homes and community doctor) and participant observation of older villagers' daily life in urban resettlement communities...

The Urban Heat Island (UHI) effect increases surface and air temperatures, affecting urban health and well-being. A well-known UHI mitigation measure is the increased roadside tree vegetation facilitating evapotranspiration and shade. In its implementation, the identification of thermally optimal street tree configurations and a quantitative assessment of how various street tree configurations impact the roadside thermal environment were deemed essential and were chosen as the main aims of the study. Twelve tropical urban canyons were categorized into three clusters representative of different street tree placement and configuration scenarios...

INTRODUCTION: Effective November 2016, the default speed limit in Seattle was lowered from 25 to 20 mph on nonarterial streets and from 30 to 25 mph on arterial streets, unless otherwise posted. In the downtown area, signs indicating the new speed limit were installed on arterials when the lower default limit took effect. Outside the downtown, new speed limit signs were installed on some arterials starting in 2018. The study evaluated effects of the speed limit reduction on crash severity in Seattle...

The review included studies that met the following criteria: (1) Study design: experimental studies, cross sectional studies, (2) Participants: individuals of all ages, (3) Exposure variables: street greenery, including street vegetation (e...

BACKGROUND: Granulomatous mycosis fungoides (GMF) is a rare form of cutaneous T-cell lymphoma characterized by a granulomatous inflammatory infiltrate. OBJECTIVE: The impact of granulomatous inflammation on the prognosis of the disease remains controversial as there are both favorable and unfavorable outcomes documented. METHODS: We performed a systematic review of 116 GMF cases previously described in the literature. RESULTS: In contrast to the classic Alibert-Bazin type of mycosis fungoides (MF), cutaneous lesions in GMF tend to involve distal extremities (lower legs, feet, hands) early in the disease course...

The story of the 1967 appearance of the powerful psychedelic 2,5-dimethoxy-4-methylamphetamine (DOM, STP) commonly omits details and often includes hyperbole and inaccuracies. It is well known how and when the drug was first distributed to the public for free by Owsley Stanley, but the role that Alexander Shulgin played in providing that material is not as well understood. In the interest of transparency and historical accuracy, this article attempts to present an accurate account of this well-known but inadequately detailed event...

Recognizing speech in noise, such as in a busy street or restaurant, is an essential listening task where the task difficulty varies across acoustic environments and noise levels. Yet, current cognitive models are unable to account for changing real-world hearing sensitivity. Here, using natural and perturbed background sounds we demonstrate that spectrum and modulations statistics of environmental backgrounds drastically impact human word recognition accuracy and they do so independently of the noise level...

BACKGROUND: Primary needle and syringe programs (NSPs) have been integral for the prevention of blood-borne virus (BBV) transmission among people who inject drugs. Despite this, many people who inject drugs face barriers accessing these services, particularly after-hours when most services are closed. To our knowledge, the St Kilda NSP, in Melbourne, Victoria, is the only primary NSP providing 24/7 dedicated stand-alone face-to-face services for people who inject drugs in Australia. We conducted an evaluation of the St Kilda NSP to assess its role and effectiveness in meeting client needs...

Outdoor Location-Based Augmented Reality (LAR) applications require precise positioning for seamless integrations of virtual content into immersive experiences. However, common solutions in outdoor LAR applications rely on traditional smartphone sensor fusion methods, such as the Global Positioning System (GPS) and compasses, which often lack the accuracy needed for precise AR content alignments. In this paper, we introduce an innovative approach to enhance LAR anchor precision in outdoor environments. We leveraged Visual Simultaneous Localization and Mapping (VSLAM) technology, in combination with innovative cloud-based methodologies, and harnessed the extensive visual reference database of Google Street View (GSV) , to address the accuracy limitation problems...

After searching and screening three databases, a total of 20 pertinent articles were included. There were six articles dedicated to the VR training of street-crossing skills for individuals with autism, nine articles focusing on the training of driving skills for individuals with ASD, and three studies examining the training of bus riding for individuals with ASD...

Nyaope is a local adulterated drug that contributes significantly to the psychosocial challenge of substance use in South Africa. Despite being a huge burden on society and the health care system, research into the deleterious effects of nyaope is limited. The aim of the present study was therefore to perform a chemical analysis of the drug and to assess its toxic effects on neuroblastoma cells. Gas chromatography-mass spectrometry (GC/MS) analysis showed that nyaope mainly consists of heroin and heroin-related products...

Outreach is an important approach to improve health and social care for women experiencing street involvement (SI) or gender-based violence (GBV). Few studies have examined outreach approaches that incorporate SI and GBV. Drawing on feminist theories and principles of community-based research, we detail an inclusive co-design approach for an outreach intervention considering these interrelated contexts. Women with lived experience, researchers, and service leaders drew on research and experiential knowledge to define outreach engagement principles: tackling GBV, personhood and relational engagement, trauma-informed engagement, and harm reduction engagement...
