Homelessness and housing stress among police detainees: results from the DUMA program

This research reaffirms the need for intensive accommodation support services to complement criminal justice responses to crime and those who have contact with the criminal justice system. Foreword It is generally accepted that a person’s living situation, in particular their experience of homelessness and housing stress, can have both long-lasting and wide-ranging consequences. For criminal justice practitioners, the task of limiting homelessness and preventing crime remain key policy priorities in need of ongoing and integrated research. This paper provides a much needed examination of homelessness and housing stress among Australia’s criminal justice population. Using data from the AIC’s Drug Use Monitoring in Australia program, this study examines the prevalence and nature of homelessness among a sample of police detainees. It is the first of its kind to examine a broader range of homelessness experiences and the reasons why some offenders have few choices but to ‘sleep rough’ or seek accommodation support. Importantly, the authors estimate that 22 percent of the detainee population is homeless or experiencing housing stress in some form; much higher than has been previously estimated. This research reaffirms the need for intensive accommodation support services to complement criminal justice responses to crime and those who have contact with the criminal justice system

Stable isotope probing: Technical considerations when resolving ¹⁵N-labeled RNA in gradients

RNA based stable isotope probing (SIP) facilitates the detection and identification of active members of microbial populations that are involved in the assimilation of an isotopically labeled compound. ¹⁵N-RNA-SIP is a new method that has been discussed in recent literature but has not yet been tested. Herein, we define the limitations to using ¹⁵N-labeled substrates for SIP and propose modifications to compensate for some of these shortcomings. We have used ¹⁵N-RNA-SIP as a tool for analysing mixed bacterial populations that use nitrogen substrates. After incubating mixed microbial communities with ¹⁵N-ammonium chloride or ¹⁵N₂ we assessed the fractionation resolution of ¹⁵N-RNA by isopycnic centrifugation in caesium trifluoroacetate (CsTFA) gradients. We found that the more isotopic label incorporated, the further the buoyant density (BD) separation between ¹⁵N- and ¹⁴N-RNA, however it was not possible to resolve the labeled from unlabeled RNA definitively through gradient fractionation. Terminal-restriction fragment length polymorphism (T-RFLP) analysis of the extracted RNA and fluorescent in situ hybridisation (FISH) analysis of the enrichment cultures provided some insight into the organisms involved in nitrogen fixation. This approach is not without its limitations and will require further developments to assess its applicability to other nitrogen-fixing environments

Genetic diversity of eukaryotic ultraphytoplankton in the Gulf of Naples during an annual cycle

Eukaryotic ultraphytoplankton (<5 μm) are an important component of phytoplankton populations, Dot blot hybridisation analysis using class level 16S rRNA gene probes as well as clone libraries were used to investigate the diversity of these ultraphytoplankton during a 15 mo period (2003 to 2004) in the Gulf of Naples. Hybridisation data showed the presence of 3 main classes, Cryptophyceae, Chrysophyceae and Prymnesiophyceae, along with lower signals from the Pelagophyceae. Clone libraries also contained these 4 classes as well as sequences from the Dictyochophyceae, Bacillariophyceae and Prasinophyceae. However, the Prymnesiophyceae gave the dominant hybridisation signal and constituted the majority of each clone library. Their diversity, with a total of 190 sequences belonging to 114 operational taxonomic units (OTUs), probably allows them to dominate the ultraphytoplankton throughout the whole year under differing environmental conditions. Over 100 of these OTUs were unique to different libraries, suggesting a succession of different taxa during the year. The Cryptophyceae were present most of the year with 1 OTU, corresponding to a Plagioselmis prolonga strain from the Gulf of Naples, being the dominant taxon (28 % of sequences). A striking result was the high hybridisation signal from the Chrysophyceae, which showed a preference for the summer months. The Pelagophyceae were present between December and March. Most (80 %) of the sequences found in the clone libraries were not identical to available 16S rRNA gene sequences, indicating a high amount of hidden diversity for these algal classes. However, sequences from Prasinophyceae Clade II (Mamiellales) were not detected in the clone libraries

Collectors on Collecting

Exhibition program from a 2002 exhibit presented in the Daniel R. Coquillette Rare Book Room at the Boston College Law Library. The exhibit brought together highlights from the collections of eight collectors, all of whom were either lawyers or collectors of law books. These collectors contributed brief reflections on their own experiences and collections to the exhibit program

Business process flow diagrams in tissue bank informatics system design, and identification and communication of best practices: the pharmaceutical industry experience

Pfizer, Inc.'s Tissue Bank, in conjunction with Pfizer's BioBank (biofluid repository), endeavored to create an overarching internal software package to cover all general functions of both research facilities, including sample receipt, reconciliation, processing, storage, and ordering. Business process flow diagrams were developed by the Tissue Bank and Informatics teams as a way of characterizing best practices both within the Bank and in its interactions with key internal and external stakeholders. Besides serving as a first step for the software development, such formalized process maps greatly assisted the identification and communication of best practices and the optimization of current procedures. The diagrams shared here could assist other biospecimen research repositories (both pharmaceutical and other settings) for comparative purposes or as a guide to successful informatics design. Therefore, it is recommended that biorepositories consider establishing formalized business process flow diagrams for their laboratories, to address these objectives of communication and strategy

Predicting Second and Third Graders' Reading Comprehension Gains: Observing Students' and Classmates Talk during Literacy Instruction using COLT.

This paper introduces a new observation system that is designed to investigate students' and teachers' talk during literacy instruction, Creating Opportunities to Learn from Text (COLT). Using video-recorded observations of 2nd-3rd grade literacy instruction (N=51 classrooms, 337 students, 151 observations), we found that nine types of student talk ranged from using non-verbal gestures to generating new ideas. The more a student talked, the greater were his/her reading comprehension (RC) gains. Classmate talk also predicted RC outcomes (total effect size=0.27). We found that 11 types of teacher talk ranged from asking simple questions to encouraging students' thinking and reasoning. Teacher talk predicted student talk but did not predict students' RC gains directly. Findings highlight the importance of each student's discourse during literacy instruction, how classmates' talk contributes to the learning environments that each student experiences, and how this affects RC gains, with implications for improving the effectiveness of literacy instruction

A Bourdieusian analysis of qualitative authorship in entrepreneurship scholarship

Empirically, this study builds on responses from leading qualitative entrepreneurship scholars.We carry out a Bourdieuan analysis of the field of entrepreneurship scholarship—particularly heterodox qualitative writing—and the way that scholars learn to play this game (habitus). It discusses unchallenged assumptions (doxa), commitment to shared stakes (illusio), the practice to achieve these stakes (practice), and the struggle for glories and riches (capital). By deploying Bourdieu’s frame, we have been able to expose key processes, structures, and relationships within qualitative entrepreneurship authorship. These offer four types of practical outcomes: guidance for good practice; insights into emotional aspects of authorship; warnings of potentially dysfunctional practices; and a celebration of our successes
