The Distribution and Abundance of Animals and Plants on the Rocky Shores of Bantry Bay
A survey of the rocky shores of Bantry Bay is described. This is intended to serve as a means by which future changes may be detected, as well as providing an account of a hitherto undescribed area of the Irish coast. The abundance of littoral animals and plants was assessed at regular vertical intervals on forty transects, and the distribution patterns of these species
are described and discussed in relation to two major environmental variables, emersion and exposure to wave action. The method adopted may be suitable as a standard method for surveying rocky shores, and this is discussed in relation to the objectives of the survey
Effects of Training on Social Work, Nursing and Medical Trainees' Knowledge, Attitudes and Beliefs Related to Screening and Brief Intervention for Alcohol Use
Indiana University's Schools of Social Work, Nursing and Medicine formed a consortium to advance education for Screening Brief Intervention and Referral to Treatment (SBIRT). Trainees participated in SBIRT training and completed data collection before, immediately after, and 30 days after a face-to-face training. The study explored participants' perceptions about the training and the likelihood of implementing SBI in practice, including attitudes and beliefs that may be predictive of SBIRT utilization in clinical practice. Results show the training targeting SBI and MI behaviors may improve participants' self-reported competence with SBI. This improvement was consistent and strong in all programs. The study results also provided a preliminary indication that the training affected participants' perception of time utilization and compensation for performing SBI
Anatomic Basis of Sharp Pelvic Dissection for Curative Resection of Rectal Cancer
The optimal goals in the surgical treatment of rectal cancer are curative resection, anal sphincter preservation, and preservation of sexual and voiding functions. The quality of complete resection of rectal cancer and the surrounding mesorectum can determine the prognosis of patients and their quality of life. With the emergence of total mesorectal excision in the field of rectal cancer surgery, anatomical sharp pelvic dissection has been emphasized to achieve these therapeutic goals. In the past, the rates of local recurrence and sexual/voiding dysfunction have been high. However, with sharp pelvic dissection based on the pelvic anatomy, local recurrence has decreased to less than 10%, and the preservation rate of sexual and voiding function is high. Improved surgical techniques have created much interest in the surgical anatomy related to curative rectal cancer surgery, with particular focus on the fascial planes and nerve plexuses and their relationship to the surgical planes of dissection. A complete understanding of rectum anatomy and the adjacent pelvic organs are essential for colorectal surgeons who want optimal oncologic outcomes and safety in the surgical treatment of rectal cancer
Population genomics meet Lagrangian simulations: Oceanographic patterns and long larval duration ensure connectivity among Paracentrotus lividus populations in the Adriatic and Ionian seas
Connectivity between populations influences both their dynamics and the genetic structuring of species. In this study, we explored connectivity patterns of a marine species with long-distance dispersal, the edible common sea urchin Paracentrotus lividus, focusing mainly on the Adriatic-Ionian basins (Central Mediterranean). We applied a multidisciplinary approach integrating population genomics, based on 1,122 single nucleotide polymorphisms (SNPs) obtained from 2b-RAD in 275 samples, with Lagrangian simulations performed with a biophysical model of larval dispersal. We detected genetic homogeneity among eight population samples collected in the focal Adriatic-Ionian area, whereas weak but significant differentiation was found with respect to two samples from the Western Mediterranean (France and Tunisia). This result was not affected by the few putative outlier loci identified in our dataset. Lagrangian simulations found a significant potential for larval exchange among the eight Adriatic-Ionian locations, supporting the hypothesis of connectivity of P. lividus populations in this area. A peculiar pattern emerged from the comparison of our results with those obtained from published P. lividus cytochrome b (cytb) sequences, the latter revealing genetic differentiation in the same geographic area despite a smaller sample size and a lower power to detect differences. The comparison with studies conducted using nuclear markers on other species with similar pelagic larval durations in the same Adriatic-Ionian locations indicates species-specific differences in genetic connectivity patterns and warns against generalizing single-species results to the entire community of rocky shore habitats

Multi-criteria ranking of corporate distress prediction models: empirical evaluation and methodological contributions
YesAlthough many modelling and prediction frameworks for corporate bankruptcy
and distress have been proposed, the relative performance evaluation of prediction models
is criticised due to the assessment exercise using a single measure of one criterion at
a time, which leads to reporting conflicting results. Mousavi et al. (Int Rev Financ Anal
42:64–75, 2015) proposed an orientation-free super-efficiency DEA-based framework to
overcome this methodological issue. However, within a super-efficiency DEA framework,
the reference benchmark changes from one prediction model evaluation to another, which
in some contexts might be viewed as “unfair” benchmarking. In this paper, we overcome
this issue by proposing a slacks-based context-dependent DEA (SBM-CDEA) framework
to evaluate competing distress prediction models. In addition, we propose a hybrid crossbenchmarking-
cross-efficiency framework as an alternative methodology for ranking DMUs
that are heterogeneous. Furthermore, using data on UK firms listed on London Stock
Exchange, we perform a comprehensive comparative analysis of the most popular corporate
distress prediction models; namely, statistical models, under both mono criterion and
multiple criteria frameworks considering several performance measures. Also, we propose
new statistical models using macroeconomic indicators as drivers of distress
