Comply or Explain: Investor Protection Through the Italian Corporate Governance Code
Authors: Bianchi Marcello , Ciavarella Angela , Novembre Valerio , Signoretti Rossella ,   CONSOB
Published: March 2011

Nearly 86% of listed Italian companies now claim to be in formal compliance with the provisions of the Italian Corporate Governance Code, which, like many codes in EU countries, give companies the option to either comply or explain their decision not to do so. But in the wake of the recent financial crisis, the effectiveness of such self‐regulatory corporate governance codes has been subjected to increasing skepticism. In particular, critics wonder whether such governance codes actually encourage the adoption of best practices and promote better governance.This article presents a governance indicator (CoRe) devised by the authors that attempts to assess the actual, or effective, levels of compliance with the Italian Corporate Governance Code in terms of listed companies' procedures for dealing with related party transactions (RPTs). The authors report that the companies' level of effective compliance with regard to RPTs is considerably lower than their publicly reported levels of formal compliance. The authors also report that higher levels of effective compliance tend to be found in companies where (1) minority shareholders have appointed one or more directors; (2) independent directors serve on important committees; and (3) there are significant holdings by institutional investors—particularly foreign investors—who participate in general shareholder meetings.

Published: March 2011

AbstractContext: Health information technology (HIT) is a national policy priority. Knowledge about the special needs, if any, of rural health care providers should be taken into account as policy is put into action. Little is known, however, about rural‐urban differences in HIT adoption at the national level.Purpose: To conduct the first national assessment of HIT in rural primary care offices, with particular attention to electronic medical record (EMR) adoption, range of capabilities in use, and plans for adoption.Methods: A national mail survey of 5,200 primary care offices, stratified by rurality using Rural‐Urban Commuting Area categories, was conducted in 2007‐2008. Regression analyses were used to assess the relationship between office characteristics and EMR adoption, capabilities used, and future adoption plans.Results: A commercial EMR system was present in 31% of offices, with no significant differences by rurality. Of offices with EMRs, 12% reported using a full range of EMR capabilities, with 51% using a basic range and 37% using less than the basic range. Large Rural (adjusted OR = 3.71, P= .022) and Small Rural (aOR = 3.75, P= .049) offices were more likely than Urban offices to use a broader range of EMR capabilities. Among offices without EMRs, those in Isolated areas were less likely to have more immediate plans to adopt (aOR = 0.19, P= .02).Conclusions: HIT adoption and use in rural primary care offices does not appear to be lower than in urban offices. The situation, however, is dynamic and warrants further monitoring.
Larval survival of two species of forensically important blowflies (Diptera: Calliphoridae) after submergence in water
Authors: SINGH Devinder , BALA Madhu 
Published: March 2011

AbstractSurvival of larvae of known ages after 2 to 6 h of submersion under water was assessed by observing pupation and adult emergence in the cases of two blowflies of forensic importance, Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart). Lowest survival occurred among 10‐h‐old larvae, which could not tolerate more than 2 h of submergence. Even with such a small period of submergence success of survival was only 33%. There were no survivors when 20‐ and 30‐h‐old larvae were submerged for more than 3 and 4 h, respectively. In the cases of 40‐, 50‐, 60‐ and 70‐h‐old larvae there were no survivors if submergence was more than 5 h. The results show that there is an inverse relationship between submergence period and survival rate: the longer the submergence period, the lesser is the survival rate. This study provides data that are potentially useful in estimating the minimum time since submergence (TSS) of a corpse during forensic investigations.

AbstractFive cultivated mulberry plant varieties, BSRM‐34, BSRM‐56, BSRM‐57, BSRM‐58 and BSRM‐59, were used to evaluate the effects of plant variety on larval and cocoon characteristics of mulberry silkworm Bombyx mori L. Silkworm larvae undergo their entire larval periods on leaves of mulberry varieties. Different larval characteristics of larval weight, larval length and larval breadth were measured in different growth stages. After rearing, the fifth instar larvae were transferred into a mountage (Chandraki) structure for cocoon rearing for spinning and cocoon production. The cocoons were then harvested and different cocoon characteristics like cocoon weight, shell weight and shell percentage; and other characters like pupal weight and effective rate of rearing were measured. The results showed statistically significant differences among different varieties on larval and cocoon characteristics. The highest performance was observed by feeding the variety BSRM‐34 in respect of the average weight of 10 mature larvae (40.5 g), single mature larval length (7.6 cm) and breadth (1.0 cm), single cocoon weight (1.4 g), shell weight (0.2 g) and pupal weight (1.2 g) while the average performance was recorded by feeding varieties BSRM‐57 and BSRM‐59. The poorest performance was showed by feeding the variety BSRM‐56 (in case of larval characters) and BSRM‐58 (in case of cocoon characteristics). These two varieties also showed the poorest performance for silk yield. Through comparing all the above parameters it was concluded that BSRM‐34 is the best mulberry variety and it is recommended that Bangladeshi farmers adopt that variety for better yield of silk.

SummaryIntroduction:  The collection of diagnostic blood specimens for routine haematological testing (RHT) is traditionally performed with tourniquet. However, the transillumination devices based on cold near‐infrared LEDs have been formerly proposed as a valuable tool for identifying reliable venous accesses, especially in patients with difficult or small veins, such as children. This study was aimed to evaluate whether a transillumination device can advantageously replace the use of the tourniquet during the procedure for collection of blood specimens for RHT and thereby eliminating the discomfort and risk of spurious results caused by excessive or prolonged venous stasis.Methods:  Two hundred and fifty volunteers were divided into five groups (G1, G2, G3, G4 and G5) to compare the results of RHT between blood sample collected with transilluminator device (left arm) and with tourniquet application (right arm) for 30 s(G1), 60 s(G2), 90 s(G3), 120 s(G4) and 180 s(G5).Results:  No significant increases were observed in any of the haematological parameters tested in G1 when compared with blood collected by the transilluminator device. From G2 to G5, significant increases were observed for the platelet count, red blood cell count, haemoglobin, haematocrit, white blood cell count, neutrophils, monocytes and eosinophils. From G3–G5, further increases were observed for lymphocytes. Clinically significant variations were, however, observed for basophils in G2; red blood cell count, haemoglobin, haematocrit and basophils in G3 and eosinophils in G3 only.Conclusion:  As such, considering that inappropriate use of the tourniquet is commonplace, we conclude that transillumination devices can represent a suitable tool to eliminate the venous stasis and to improve the quality of phlebotomy procedures.

SummaryThe prokaryotic community composition of activated sludge from a seawater‐processing wastewater treatment plant (Almeria, Spain) was investigated by using the rRNA approach, combining different molecular techniques such as denaturing gradient gel electrophoresis (DGGE), clone libraries and in situ hybridization (FISH and CARD‐FISH). Most of the sequences retrieved in the DGGE and the clone libraries were similar to uncultured members of different phyla. The most abundant sequence recovered from Bacteria in the clone library corresponded to a bacterium from the Deinococcus–Thermus cluster (almost 77% of the clones), and the library included members from other groups such as the Alpha, Gamma and Delta subclasses of Proteobacteria, the Bacteroidetes and Firmicutes. Concerning the archaeal clone library, we basically found sequences related to different orders of methanogenic Archaea, in correspondence with the recovered DGGE bands. Enumeration of DAPI (4′,6‐diamidino‐2‐phenylindole) stained cells from two different activated sludge samples after a mechanical flocculation disruption revealed a mean cell count of 1.6 × 109 ml−1. Around 94% of DAPI counts (mean value from both samples) hybridized with a Bacteria specific probe. Alphaproteobacteria were the dominant bacterial group (36% of DAPI counts), while Beta‐, Delta‐ and Gammaproteobacteria, Bacteroidetes, Actinobacteria and Firmicutes contributed to lower proportions (between 0.5–5.7% of DAPI counts). Archaea accounted only for 6% of DAPI counts. In addition, specific primers for amplification of the amoA (ammonia monooxygenase) gene were used to detect the presence of Beta, Gamma and archaeal nitrifiers, yielding positive amplifications only for Betaproteobacteria. This, together with negative in situ hybridizations with probes for well‐known nitrifiying bacteria, suggests that nitrification is performed by still undetected microorganisms. In summary, the combination of the three approaches provided different and complementary pictures of the real assemblage composition and allowed to get closer to the main microorganisms involved in key processes of seawater‐processing activated sludge.
Qualitative methods to ensure acceptability of behavioral and social interventions to the target population
Authors: Ayala Guadalupe X. , Elder John P. 
Published: March 2011

AbstractObjectives: This paper introduces qualitative methods for assessing the acceptability of an intervention.Methods: Acceptability refers to determining how well an intervention will be received by the target population and the extent to which the new intervention or its components might meet the needs of the target population and organizational setting. In this paper, we focus on two common qualitative methods for conducting acceptability research and their advantages and disadvantages: focus groups and interviews.Results: We provide examples from our own research and other studies to demonstrate the use of these methods for conducting acceptability research and how one might adapt this approach for oral health research.Discussion: We present emerging methods for conducting acceptability research, including the use of community‐based participatory research, as well as the utility of conducting acceptability research for assessing the appropriateness of measures in intervention research.
Two generalizations of the PRV conjecture
Authors: Montagard P. L. , Pasquier B. , Ressayre N. 
Published: March 2011

AbstractLet G be a complex connected reductive group. The Parthasarathy–Ranga Rao–Varadarajan (PRV) conjecture, which was proved independently by S. Kumar and O. Mathieu in 1989, gives explicit irreducible submodules of the tensor product of two irreducible G-modules. This paper has three aims. First, we simplify the proof of the PRV conjecture, then we generalize it to other branching problems. Finally, we find other irreducible components of the tensor product of two irreducible G-modules that appear for ‘the same reason’ as the PRV ones.
Utility of screening for hepatocellular carcinoma among cirrhotics
Authors: Niravath Polly , Hayes Teresa , Hilsenbeck Susan 
Published: March 2011

BackgroundScreening known cirrhotics for hepatocellular cancer (HCC) has long been a contentious topic. Studies to date have failed to conclusively prove or disprove the validity of α-fetoprotein (AFP) and hepatic ultrasound as screening mechanisms for HCC among cirrhotics, particularly in the American population. It is not clear whether these screening mechanisms provide any benefit in terms of reduced morbidity and mortality.MethodsThe study examined all patients with liver cirrhosis who developed HCC at the Michael E DeBakey VA Medical Center between 1999 and 2005. Those who were screened with AFP and/or imaging (either ultrasound, triphasic liver protocol CT or MRI) were compared with those patients who were not screened at all. The screened and unscreened patients were compared in terms of Barcelona Clinic Liver Cancer (BCLC) stage at the time of diagnosis.ResultsStatistical analysis revealed a significant difference between the screened and unscreened groups in terms of BCLC stage at diagnosis, with the unscreened group being diagnosed at later stages than the screened group. Of the 155 patients observed, 26 were appropriately screened, and 129 were not. The BCLC stages at diagnosis for the two groups were as follows: screened patients: 34.6%, 38.5%, 7.7% and 19.2% for BCLC stages A, B, C and D, respectively; unscreened patients: 12.4%, 24.8%, 27.1% and 35.7% for BCLC stages A, B, C and D, respectively. The different trend in the two groups was found to be statistically significant, with a p value of 0.004. Furthermore, among the screened group, no particular method of screening (AFP vs imaging vs combination) was shown to be superior to another.ConclusionsScreening for HCC among cirrhotics using AFP and/or imaging every 6 months does correlate with HCC diagnosis at an earlier BCLC stage, thus portending better treatment options and improved prognosis. Therefore, screening all known cirrhotics for HCC may lead to decreased mortality.

Background and aims15–30% of cases of cervical intraepithelial neoplasia grades 2–3 (CIN2–3) detected in punch biopsies regress spontaneously (ie, show CIN1 or less in the follow-up cone). Epithelial retinoblastoma protein (pRb), tumour suppressor protein (p53), HPV genotype and immunoreactive cells have been reported to be helpful in predicting regression but their interaction in regression prediction is unknown.Material and methods55 cases of CIN2–3 in cervical biopsies with subsequent cervical cones were studied retrospectively to assess how epithelial biomarkers, immunoreactive cells (with immunohistochemistry) and high-risk (hr) HPV genotypes (by the AMPLICOR and linear array tests) prognostically interact with epithelial pRb and p53.Results18% of CIN2–3s regressed (median biopsy–cone interval of 12.0 weeks, range 5.0–34.1 weeks). CIN2–3s that regressed had higher epithelial pRb and p53, lower stromal CD25+and CD138+, and higher CD8 cells than persistent lesions. They also had higher ratios of CD4+/CD25+and CD8+/CD25 in stroma and epithelium. HPV16 correlated with low pRb and low CD8+. With multivariate analysis a combined high ratio of CD8+/CD25+in the stroma, high epithelial pRb and p53 expression had independent value to predict the regression.ConclusionsCIN2–3 lesions with a non-hrHPV16 infection, high ratios of stromal CD8+/CD25+and high epithelial expression of pRb or p53 are associated with spontaneous regression.
Peritoneal mesothelial hyperplasia associated with gynaecological disease: a potential diagnostic pitfall that is commonly associated with endometriosis

Published: March 2011

AimsTo describe the clinicopathological features of florid peritoneal mesothelial hyperplasia associated with gynaecological disease.MethodsReview of a series of 44 cases where there was significant peritoneal mesothelial proliferation, usually on the surface of the ovary, which resulted in diagnostic problems, often including a consideration of malignancy.ResultsFlorid mesothelial proliferation was associated with a variety of benign and malignant lesions, most commonly endometriosis. The most characteristic morphological appearance was that of small bland tubules and nests and cords of cells often embedded in fibrous tissue, sometimes with a linear arrangement. In a minority of cases, there were closely packed small glands and papillae resulting in mimicry of a serous proliferation; psammoma bodies were present in one such case. In several cases, the groups of mesothelial cells either exhibited true lymphovascular invasion or were surrounded by spaces closely simulating lymphovascular invasion. Although most cases were appreciated to represent a reactive mesothelial proliferation, several were referred with a presumed or possible diagnosis of mesothelioma, low-grade serous carcinoma, adenocarcinoma, adenomatoid tumour or Sertoli cell tumour. Positive staining with calretinin and negative staining with Ber-EP4 often helped to identify the cells as mesothelial rather than epithelial.ConclusionsFlorid peritoneal mesothelial hyperplasia can occur in association with a variety of gynaecological disorders. Recognition of this phenomenon and appreciation that it can produce worrisome histological patterns, particularly when associated with endometriosis, is key to reaching the correct diagnosis.
Late Holocene glacial activity in Manatee Valley, southern Coast Mountains, British Columbia, Canada
Authors: Koehler Lindsey , Smith Dan J. 
Published: March 2011

The dendroglaciologic and lichenometric research methodologies employed in this study provide a perspective of glaciological conditions from 5 ka to present in a remote headwater area of the British Columbia Coast Mountains. Since Holocene ice fronts of four glaciers at this site periodically extended below treeline, previous glacier advances overrode and buried forests beneath till deposits. This study suggests that glaciers were expanding into standing forests at 4.76 and 3.78 ka. Following glacier expansion at 3.78 ka, a period of recession ensued when glaciers withdrew upvalley long enough for the development of deep pedogenic surfaces and the growth of trees exceeding 300 years. Investigations at Beluga and Manatee glaciers benchmark a subsequent episode of significant glacial expansion at 2.42 ka referred to as the “Manatee Advance”. This advance has regional correlatives and is distinguished from the Tiedemann Advance at Manatee Glacier by documentation of substantive ice front retreat between the two episodes. Examination of Little Ice Age (LIA) deposits in the study area allowed for presentation and application of a revised Rhizocarpon spp. lichen growth curve. Lichenometric surveys of lateral moraines associated with Beluga, Manatee, and Oluk glaciers provided limited insight into their early LIA behaviour but record advances during the 15th and 16th centuries. Locally, glaciers achieved their maximum LIA size prior to an early to mid 18th century moraine-building event. This reconstruction of Holocene glacial history offers insights consistent with the emerging record of glacier activity described for other southern British Columbia Coast Mountain glaciers.

The Roy Group in the Chibougamau area of the Abitibi subprovince, Southeastern Superior craton, Quebec, exemplifies Archean volcanic evolution. The Roy Group formed in two volcanic cycles, with voluminous basal mafic tholeiitic volcanic rocks being capped by a thin succession of calc-alkaline felsic volcanic rocks, banded iron formations, and cherts that represent regional stratigraphic markers. The Gilman Formation is thought to represent the mafic base of the 2nd Roy Group volcanic cycle. Our new mapping reveals that the Gilman Formation (North of the Lac Doré Layered intrusive complex) can be subdivided into a tholeiitic lower part (David member), a calc-alkaline extrusive sequence (Allard member), and a tholeiitic, more mafic upper part (Bruneau Formation, newly defined here). New U–Pb zircon ages on Allard member tuffs (2726.6 ± 0.7 Ma) are within error of those obtained from rhyolites of the Waconichi Formation (2728.2–2728.7 Ma), which underlies the Gilman Formation. These ages, along with geochemical and lithological similarities, imply that the Allard member belongs to the Waconichi Formation and that the David member occupies the same stratigraphic position as the Obatogamau Formation. The upper part of the former Gilman Formation is reassigned to the new Bruneau Formation. A thin transitional calc-alkaline basalt unit at the base of the Allard member is geochemically similar to basalts occurring at the top of the Lemoine member of the Waconichi Formation near the Lemoine mine, suggesting that the Allard member is slightly younger than the Lemoine member, and that its base (also associated with iron formation, breccia, and chert) represents a regional stratigraphic break favourable for volcanogenic-hosted massive sulphide (VHMS) exploration.
Undrained shear strength properties of organic harbor mud at low consolidation stress levels

Published: March 2011

Dredging operations in European harbors for maintenance of navigable water depth produce vast amounts of harbor mud. Between 2005 and 2007, the second largest harbor construction project in Germany was designed as a pilot study, using dredged harbor mud as backfill material to avoid expensive deposition or ex situ treatment. During this project, strong surface deformations of the backfill highlighted the need for an improved assessment of undrained shear strength of naturally liquid harbor mud. The strength of harbor mud cannot be measured accurately under corresponding low in situ effective stress levels by standard laboratory tests. Therefore, a large-scale oedometer cell with a diameter of 22 cm was designed, providing the opportunity to perform vane shear measurements during consolidation. This study shows that East Harbor mud is a very sensitive, organogenic clay of extremely high plasticity, exhibiting very small undrained shear strength when compared with other cohesive soils. Both the peak and residual undrained shear strengths are shown to increase about 3%–4% per log-cycle increase in secondary compression time (days).
