A Brief Update on the CMZoom Survey
No full textThe inner few hundred parsecs of the Milky Way, the Central Molecular Zone (CMZ), is our closest laboratory for understanding star formation in the extreme environments (hot, dense, turbulent gas) that once dominated the universe. We present an update on the first large-area survey to expose the sites of star formation across the CMZ at high-resolution in submillimeter wavelengths: the CMZoom survey with the Submillimeter Array (SMA). We identify the locations of dense cores and search for signatures of embedded star formation. CMZoom is a three-year survey in its final year and is mapping out the highest column density regions of the CMZ in dust continuum and a variety of spectral lines around 1.3 mm. CMZoom combines SMA compact and subcompact configurations with single-dish data from BGPS and the APEX telescope, achieving an angular resolution of about 4" (0.2 pc) and good image fidelity up to large spatial scales
Assessing the impact of laws controlling the online availability of 25I-NBOMe, AH-7921, MDPV and MXE – outcomes of a semi-automated e-shop monitoring
Get PDFAims: The indicator of availability has been used in the risk assessment (RA) of new psychoactive substances (NPS). This paper aims to examine the pre- and post-control availability of 25INBOMe, AH-7921, MDPV and MXE, which were assessed by the EMCDDA. Methods: Data were collected by a semi-automated software tool (I-TREND SASF) on e-shops in national languages (Czech, French, Dutch, Polish and English) that offered shipping of these compounds into the respective countries; frequency analysis was used. Findings: The number of e-shops selling these substances decreased between III/2014 and XII/2015 (except for AH-7921). Both increases and decreases were found on the country-level for all the compounds (except for an overall decrease for MXE). In one instance an NPS disappeared from this market in 2015 (25I-NBOMe in NL); 25I-NBOMe and AH-7921 in France and AH-7921 in Poland appeared for the first time in 2015 after they were put under control. The e-shops listing AH-7921, 25I-NBOMe and MDPV in XII/2015 ranked higher in terms of ‘‘popularity’’ than in III/2014. The IP addresses were more likely to be outside the EU in 2015 than in 2014. Conclusions: We found no evidence that national-level compound bans contributed to the changes in online NPS markets. Indicators of the accessibility, availability, popularity, and IP origin should be considered in RA. Data triangulation with street markets and the darknet is needed as well as more research into the ‘‘displacement’’ and ‘‘replacement’’ effects of control laws
'Out of hours' social work : a study of local authority emergency duty
No full textThroughout the United Kingdom it is likely that 'out of hours', the smallest number of social workers is covering the largest geographical areas, the highest proportion of referrals, the most hours per week with the least support and in some of the most dangerous situations. For nearly thirty years, the majority of the working week has been staffed by out of hours social workers, and yet no systematic research has ever been undertaken into any aspects of this social work service. The focus of this research then is local authority emergency duty team (EDT) social work. From a variety of perspectives and using a range of methods the researcher examines the past, present and potential future nature of out of hours social work. As an EDT worker and researcher simultaneously, the author highlights the types and variability of his own assessments and those made by colleagues locally and nationally. Having established that EDT social work deals with significant occurrences after hours, this research questions whether conventional expectations of social work assessment are applicable 10 circumstances that are radically different from day-time work. Employing statistical surveys, questionnaires, interviews and autobiographical commentary, this research collates and analyses EDT social work practice issues seeking to establish an assessment framework that can be applied to the generic, urgent and statutory demands that EDT and daytime social workers frequently face. The framework combines the qualitative and the quantitative, academic with practitioner, the personal and the political and reflects the nature of EDT social work. Addressing a research void, this study clarifies and attempts to improve out of hours social work practice, including that of the researcher. This research presents a systematic analysis of the risk assessments, the decision-making processes and the crisis work undertaken by the most experienced group of social workers in Britain. The findings of this research should be of interest to those involved in out of hours social work, but may also have relevance to (social) workers undertaking (risk) assessments of service users

No full textSUIDS : a resource-efficient intrusion detection system for ubiquitous computing environments
No full textThe background of the project is based on the notion of ubiquitous computing. Ubiquitous computing was introduced as a prospective view about future usage of computers. Smaller and cheaper computer chips will enable us to embed computing ability into any appliances. Along with the convenience brought by ubiquitous computing, its inherent features also exposed its weaknesses. It makes things too easy for a malicious user to spy on others. An Intrusion Detection System (IDS) is a tool used to protect computer resources against malicious activities. Existing IDSs have several weaknesses that hinder their direct application to ubiquitous networks. These shortcomings are caused by their lack of considerations about the heterogeneity, flexibility and resource constraints of ubiquitous networks. Thus the evolution towards ubiquitous computing demands a new generation of resource-efficient IDSs to provide sufficient protections against malicious activities. SUIDS is the first intrusion detection system proposed for ubiquitous computing environments. It keeps the special requirements of ubiquitous computing in mind throughout its design and implementation. SUIDS adopts a layered and distributed system architecture, a novel user-centric design and service-oriented detection method, a new resource-sensitive scheme, including protocols and strategies, and a novel hybrid metric based algorithm. These novel methods and techniques used in SUIDS set a new direction for future research and development. As the experiment results demonstrated, SUIDS is able to provide a robust and resource-efficient protection for ubiquitous computing networks. It ensures the feasibility of intrusion detection in ubiquitous computing environments
