Neonatal sepsis (NS) occurs in neonates within 28 days, especially preterm infants. The dysregulation of miRNAs is widely detected in NS. The study investigated the expression changes and clinical significance of miR-129-5p in NS patients and further explored the regulatory role of miR-129-5p in the LPS-induced inflammatory response in monocytes. A total of 75 neonates with NS and 84 neonates without NS were recruited. qRT-PCR was used for the measurement of miR-129-5p expression. The receiver operating characteristic (ROC) curve was constructed for diagnostic value analysis. ELISA was used to detect the concentration of inflammatory cytokines. Monocytes were isolated from the blood of neonates to investigate the role of miR-129-5p in the LPS-induced inflammatory response in vitro. miR-129-5p was low expressed in the serum of NS cases compared with controls. Serum miR-129-5p had a diagnostic value for NS with a sensitivity of 82.7% and specificity of 79.8%. There was close association for serum miR-129-5p with TNF-α (r = -0.652, p < 0.001) and IL-8 (r = -0.700, p < 0.001) levels in NS patients. Overexpression of miR-129-5p reversed the increasing trend of TNF-α and IL-8 induced by LPS, whereas miR-129-5p downregulation aggravated the increase of TNF-α and IL-8 induced by LPS in monocytes. MiR-129-5p was downregulated in the serum of NS patients, and it might be a promising biomarker for disease diagnosis. Overexpression of miR-129-5p alleviated the inflammatory response of NS.

AbstractCould it be right to convict and punish defendants using only statistical evidence? In this paper, I argue that it is not and explain why it would be wrong. This is difficult to do because there is a powerful argument for thinking that we should convict and punish defendants using statistical evidence. It looks as if the relevant cases are cases of decision under risk and it seems we know what we should do in such cases (i.e., maximize expected value). Given some standard assumptions about the values at stake, the case for convicting and punishing using statistical evidence seems solid. In trying to show where this argument goes wrong, I shall argue (against Lockeans, reliabilists, and others) that beliefs supported only by statistical evidence are epistemically defective and (against Enoch, Fisher, and Spectre) that these epistemic considerations should matter to the law. To solve the puzzle about the role of statistical evidence in the law, we need to revise some commonly held assumptions about epistemic value and defend the relevance of epistemology to this practical question.

Purpose In this paper, faculty librarians at an academic institution explore the ethical dimensions of conducting research with user-generated social networking service (SNS) data. In an effort to guide librarian-researchers, this paper first offers a background discussion of privacy ethics across disciplines and then proposes a library-specific ethical framework for conducting SNS research. Design/methodology/approach By surveying the literature in other disciplines, three key considerations are identified that can inform ethical practice in the field of library science: context, expectation, and value analysis. For each of these considerations, the framework is tailored to consider ethical issues, as they relate to libraries and our practice as librarian-researchers. Findings The unique role of the librarian-researcher demands an ethical framework specific to that practice. The findings of this paper propose such a framework. Practical implications Librarian-researchers are at a unique point in our history. In exploring SNSs as a source of data to conduct research and improve services, we become challenged by conflicting and equally cherished values of patron privacy and information access. By evaluating research according to context, expectations, and value, this framework provides an ethical path forward for research using SNS data. Originality/value As of this paper’s publication, there is no existing ethical framework for conducting SNS research in libraries. The proposed framework is informed both by library values and by broader research values, and therefore provides unique guidelines for the librarian-researcher.

Abstract This comment addresses the role of sampling error in extreme value analysis. A note published in this journal claimed that Weibull’s 1939 estimator for sample probability has a unique status that invalidates all other estimators and renders invalid all of the developments of unbiased distribution-dependent estimators made since 1939. The note concluded that the use of distribution-dependent estimators should be abandoned and that many estimates of the weather-related risks should be reevaluated and the related building codes and other related regulations updated. This comment uses rigorous statistical proofs to make the diametrically opposite case: namely, that development of distribution-dependent estimators has resulted in an improvement in accuracy over the past half century and that no changes are required to the basis of weather-related building codes and regulations. These rigorous proofs are supplemented by sampling experiments that demonstrate their validity. This comment provides an introduction to the basic statistical concepts of the statistical modeling of extremes, including unbiased estimators for the model parameters.

Sustainable Value Analysis (SVA) [F. Figge, T. Hahn, Ecol. Econ. 48(2004) 173-187] is a method formeasuring sustainability performance consistent with the constant capital rule and strongsustainability. SVA compares eco-efficiency of a firm relative to some benchmark. The choice of thebenchmark implies some assumptions regarding the underlying production technology. This paperpresents a rigorous examination of the role of benchmark technology in SVA. We show that Figge andHahn’s formula for calculating sustainable value implies a peculiar linear benchmark technology. Wepresent a generalized formulation of sustainable value that is not restricted to any particular functionalform and allows for estimating benchmark technology from empirical data. Our generalized SVAformulation reveals a direct link between SVA and frontier approaches to environmental performancemeasurement and facilitates statistical hypotheses testing concerning the benchmark.

Goal – the purpose of the article is to present the significance and role of institutional coherence in the development and evolution of corporate governance in Poland. Research methodology – a review of the literature on examining the specificity of knowledge about the role of institutional coherence in the development and evolution of corporate governance in Poland and analysis and assessment of the changes in good practice codes in Poland. Score/results – a systemic approach to the issue of corporate governance reveals that it is a collection of both formal and informal institutions. Through mutual interac tion, corporate governance rules lead to the emergence of a relatively stable and predictable environment in which enterprises and their stakeholders can operate. Originality/value – analysis of good practice codes in Poland reveals that the process of their adjustment to the current social and cultural norms, as well as to the expectations of the market, can be positively evaluated, as evidenced by the fact that their new editions continue to be published. The provisions which appear in good practice codes year by year adequately reflect the needs and expectations of the market.
