Apresenta uma metodologia operacional integrada, utilizando técnicas de repositórios de dados (data warehousing) e mineração de dados (data mining), e combinando ferramentas estatísticas com reconhecimento de padrões. Tendo em vista a utilização de recursos, o objetivo principal é chegar a um entendimento melhor do comportamento de comunidades de usuários. O anonimato dos usuários fica inteiramente assegurado na aplicação do modelo, pelo qual são processados os dados oriundos de arquivos transacionais da biblioteca. O próprio processo da bibliomineração consiste basicamente em coletar, depurar e anonimizar os dados, visando, precipuamente, a descoberta de padrões subjacentes. Os resultados podem ser combinados com diferentes variáveis, antes de sua utilização na tomada de decisão pela Administração da biblioteca. In order to get a better understanding of library user communities and to improve resource utilization, the author proposes an integrated operational application of data warehousing and datamining, combining statistical and pattern recognition tools, both integrated under a new concept named bibliomining. With the application of this model to transactional records of the library, patron privacy is fully respected through the creation of an anonymized version of the operational data, before reformatting them for bibliomining analysis. The bibliomining process itself consists mainly of collecting, cleaning and anonymizing the data, in order to discover underlying behavior patterns. The results can be combined with several variables, before being used to improve decision-making by the library administration.

As fumigants face increasing regulatory restrictions, resistance, and consumer pushback, it is vital to expand the integrated pest management (IPM) chemical toolkit for stored products. The production of biomass derived insecticides (e.g., bio-oil fraction) from byproducts of biofuel production may be a promising alternative source of chemistries for controlling stored product insects. These potential insecticidal bio-oils were fractionated based on boiling points (ranging from 115 to 230°C in one series and 245–250°C in another). Fractions were analyzed using GC-MS, and were found to be unique in composition. The lethality of these fractions was tested on Tribolium castaneum, Tribolium confusum, and Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae). Fractions were tested at concentrations ranging from 5–260 mg/ml to screen for efficacy against adults for durations of 2–8 hr sprayed on concrete arenas. In addition, a separate assay evaluated adult emergence of larvae after 6 wk with supplemental food in arenas, while repellency was evaluated against four stored product insect species in a laminar wind tunnel. A greenhouse gas (GHG) emissions life cycle assessment was also performed, which found the use of the bio-oil fraction could reduce GHG emissions associated with the insecticide supply chain by 25–61% relative to a fossil-fuel based insecticide or pyrethroid. While adults were largely unaffected, we found that larval emergence was significantly suppressed compared to controls by roughly half or more. We also determined that there was minimal repellency to most fractions by most species. We conclude that the use of bio-oil fractions is a climate-friendly choice that may support IPM programs.

As digital technologies are becoming embedded in all aspects of life, cyber attacks can come from many directions. A significant proportion of these attacks pose serious risks to critical data, infrastructure and processes within all manner of organisations, both large and small.

Objectives: Until the introduction of fidaxomicin, antimicrobial treatment for Clostridium difficile infection (CDI) was limited to metronidazole and vancomycin. The changing epidemiology of CDI and the emergence of epidemic C. difficile PCR ribotype 027 necessitate continued surveillance to identify shifts in antibiotic susceptibility. ClosER, currently the largest pan-European epidemiological study of C. difficile ribotype distribution and antibiotic susceptibility, aimed to undertake antimicrobial resistance surveillance pre- and post-introduction of fidaxomicin.\ud \ud \ud \ud Methods: Between July 2011 and July 2014, 39 sites across 22 European countries submitted 2830 C. difficile isolates for ribotyping, toxin testing and susceptibility testing to metronidazole, vancomycin, fidaxomicin, rifampicin, moxifloxacin, clindamycin, imipenem, chloramphenicol and tigecycline.\ud \ud \ud \ud Results: Ribotypes 027, 014, 001, 078, 020, 002, 126, 015 and 005 were most frequently isolated, and emergent ribotypes 198 and 356 were identified in Hungary and Italy, respectively. All isolates were susceptible to fidaxomicin, with scarce resistance to metronidazole (0.2%, 6/2694), vancomycin (0.1%, 2/2694) and tigecycline (0%). Rifampicin, moxifloxacin and clindamycin resistance was evident in multiple ribotypes. Lack of ribotype diversity correlated with greater antimicrobial resistance. Epidemic ribotypes (027/001) were associated with multiple antimicrobial resistance, and ribotypes 017, 018 and 356 with high-level resistance. Additional factors may also influence local ribotype prevalence.\ud \ud \ud \ud Conclusions: Fidaxomicin susceptibility was retained post-introduction, and resistance to metronidazole and vancomycin was rare. Continued surveillance is needed, with more accurate classification and clarification of ribotype subtypes to further understand their role in the spread of resistance. Other factors may also influence changes in prevalence of C. difficile ribotypes with reduced antibiotic susceptibility.

New ways to engage students in learning can be most meaningful if we provide opportunities for them to engage with each other and forge an understanding of the narrative behind the lessons.

In this paper, we examine the eect of "choice fatigue"on decision making. We exploit a natural experiment in which voters face the same contest at dierent ballot positions due to dierences in the number of local issues on their ballot. Facing more decisions before a given contest signi…cantly increases the tendency to abstain or rely on decision shortcuts, such as voting for the status quo or the …rst listed candidate. We estimate that, without choice fatigue, abstentions would decrease by 8%, and 6% of the propositions in our dataset would have passed rather than failed.
