Callers’ experiences of contacting a national suicide prevention helpline
No full textBackground: Helplines are a significant phenomenon in the mixed economy of health and social care. Given the often anonymous and fleeting nature of caller contact, it is difficult to obtain data about their impact and how users perceive their value. This paper reports findings from an online survey of callers contacting Samaritans emotional support services. Aims: To explore the (self-reported) characteristics of callers using a national suicide prevention helpline and their reasons given for contacting the service, and to present the users’ evaluations of the service they received. Methods: Online survey of a self-selected sample of callers. Results: 1,309 responses were received between May 2008 and May 2009. There were high incidences of expressed suicidality and mental health issues. Regular and ongoing use of the service was common. Respondents used the service for complex and varied reasons and often as part of a network of support. Conclusions: Respondents reported high levels of satisfaction with the service and perceived contact to be helpful. Although Samaritans aims to provide a crisis service, many callers do not access this in isolation or as a last resort, instead contacting the organization selectively and often in tandem with other types of support

On the Scalability of Ad Hoc Wireless Networks
No full text... considers the problem of scaling ad hoc wireless networks now being applied to urban mesh and sensor networks scenarios. Ad hoc networks involve multi-hop communication which has inherent scaling problems in that throughput per node drops as the square root of the number of nodes in the network. We investigate mechanisms for improving performance and scalability of multi-hop wireless networks, with focus on system architecture and routing protocol aspects. First we propose a generalized multi-tier hierarchical hybrid network with three tiers of radio nodes: low-power end-user mobile nodes (MN) at the lowest tier, higher power radio forwarding nodes (FN) that support multi-hop routing at intermediate level, and wired access points (AP) at the highest level. We present an analytical model for the capacity of the proposed network and identify conditions on transmission range and node density for scalability to be maintained. From the derived upper and lower bounds, it is shown that the low-tier capacity increase linearly with the number of FN’s, and the high-tier capacity grows linearly with the number of AP’s in the scaling region. The analytically obtained capacity results are validated with detailed system simulations for dense network scenarios. The simulation study also examines the allocation of separate channels t
Meeting the Spirit of Place: Romantic Experience of the Suli Mountains in Epirus in the Nineteenth‑Century Travelogues from Greece
No full textThe article concerns the 19th century travelogues from the Suli Mountains in South Epirus. The corpus consists of twelve texts (eleven written in English and one in French), which are discussed in the context of engravings sketched by the travellers. Taking into account the Romantic character of the 19th century mountain travels, the analysis focuses on the category of individual space perception. The author discusses various Romantic elements of the travelogues. The most typical travellers’ practices included experiencing the sublime of the mountain landscape, recalling the tragic history of Suli, reflecting upon the passage of time, expressing melancholy and awe, as well as observing the night scenery. The article closes with some remarks on the influence of the Romantic vision of Suli on Greek historiography.Artykuł powstał w ramach programu Międzynarodowe Projekty Doktoranckie Fundacji na rzecz Nauki Polskiej, współfinansowanego przez Unię Europejską w ramach Europejskiego Funduszu Rozwoju Regionalnego.Ewa Róża Janion – dr, hellenistka, kulturoznawczyni, absolwentka Międzynarodowych Studiów Doktoranckich na Wydziale „Artes Liberales” Uniwersytetu Warszawskiego.

Mesh properties for rans simulations of airfoil-shaped profiles: A case study of rudder hydrodynamics
No full textA good mesh is a prerequisite for achieving reliable results from Computational Fluid Dynamics (CFD) calculations. Mesh properties include mesh types, computational domain sizes, and node distributions. However, in literature, we found no clear consensus about what these properties should be. In this article, we performed a case study on ship rudders to determine what the suitable mesh properties are for airfoil-shaped profiles. A classic NACA 0012 profile is chosen as an example, and commercial packages ANSYS ICEM are applied for meshing with an ANSYS Fluent solver. With a strategy in consideration of relationships among different mesh properties, a comprehensive parametric investigation is conducted to study the impacts of these properties on the accuracy of rudder hydrodynamic coefficients obtained by CFD methods. The step-by-step study outputs recommended Reynolds numbers, domain sizes, and near-and far-field node distributions for mesh types with distinct topology structures, i.e., C-mesh, O-mesh, H-mesh, and Hybrid-mesh. Specifically, the study shows that a critical Reynolds number is needed for the perspective of efficiency, while a domain extending 60 times of the chord length enables the boundary effects to be negligible. As for node distributions, the near-field nodes should be treated carefully, compared with those in the far-field. After that, corresponding mesh properties for different calculation objectives are illustrated in detail based on the characteristics of mesh types mentioned above. With the proposed strategy for mesh refinements, impacts of different mesh properties on rudder hydrodynamics are clarified and recommended settings are applicable for other airfoil-shaped profiles such as wind turbines and marine propellers.Ship Design, Production and Operation
An Ionic Liquid Facilitates the Proliferation of Antibiotic Resistance Genes Mediated by Class i Integrons
No full text Ionic liquids (ILs), as "environmentally friendly" replacements for industrial volatile organic solvents, have been widely and recently applied in the chemical industry. However, few data have been collected regarding the toxicity and potential environmental effects of ILs, which are fairly important for preparing for their potential release into the environment. In this study, the IL 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]) was tested for its ability to promote the proliferation and dissemination of antibiotic resistance genes (ARGs) in environmental bacteria. In freshwater microcosms, [BMIm][PF6] (0.5 g/L) significantly enhanced the abundance of the sulI gene (500-fold greater than in untreated controls). Meanwhile, [BMIm][PF6] significantly increased the abundance of class I integrons, which play a key role in ARG dissemination. A positive correlation (p < 0.01) between the intI and sulI genes suggested that [BMIm][PF6]-facilitated sulI propagation was mediated by class I integrons. This idea was supported by sequencing, which showed the sulI locus in the 3′ region of class I integrons. Class I integron transfer experiments between different indigenous strains of Alcaligenes sp. (SMX R ) and Acinetobacter sp. (Str R ) were conducted to show that the horizontal transfer frequency of class I integrons was up to 88-fold higher in the presence of an IL. An IL increased cell membrane permeability as evidenced by flow cytometry, thereby assisting sulI gene transfer mediated by class I integrons. This is the first report that ILs facilitate the proliferation of ARGs in environmental bacteria and thus increase risks to public health.</p
