Downward Bias

This chapter provides an analytical survey and synthesis of economic literature on intergenerational mobility in developing countries, with a focus on data and methodological challenges. Sample truncation from co-residency and measurement error cause substantial downward bias in intergenerational regression coefficient, whereas intergenerational correlation and intergenerational rank correlation are more robust to such data limitations. To understand heterogeneity, reliable estimates of both the intercept and the slope are necessary. The OLS estimate of the intercept is biased upward, but less so in the rank–rank regression. Sibling correlation is a broader measure of mobility, especially convenient with limited data. Estimating intergenerational causal effects is challenging as it requires long panel data. A promising alternative is to focus on the causal effects of policies on measurement of relative and absolute mobility, without disentangling the role of genetic inheritance.

The paper surveys the main directions of political-economic research, i.e. variants of economic and political approaches endogenizing political processes in economic models and applying economic methods to policy studies. It analyses different versions of political-economic research in different segments of scientific community: political economics, evolutionary theory of economic policy, international political economy, formal political science and theory of economic power; main methodological assumptions, content and results of positive studies are described. The author also considers the role of political-economic approach in the normative research in economics.

Photodynamic Therapy (PDT) is a promising alternative treatment for malignancies based on photochemical reaction induced by Photosensitizers (PS) under light irradiation. Recent studies show that PDT caused the abundant release of exosomes from tumor tissues. It is well-known that exosomes as carriers play an important role in cell-cell communication through transporting many kinds of bioactive molecules (e.g. lipids, proteins, mRNA, miRNA and lncRNA). Therefore, to explore the role of exosomes in photodynamic anticancer therapy has been attracting significant attention. In the present paper, we will briefly introduce the basic principle of PDT and exosomes, and focus on discussing the role of exosomes in photodynamic anticancer therapy, to further enrich and boost the development of PDT.

Abstract Background Brain arteriovenous malformations (bAVM) may rupture causing disability or death. BAVM vessels are characterized by abnormally high flow that in general triggers expansive vessel remodeling mediated by cyclo-oxygenase-2 (COX2), the target of non-steroidal anti-inflammatory drugs. We investigated whether COX2 is expressed in bAVMs and whether it associates with inflammation and haemorrhage in these lesions. Methods Tissue was obtained from surgery of 139 bAVMs and 21 normal Circle of Willis samples. The samples were studied with immunohistochemistry and real-time quantitative polymerase chain reaction (RT-PCR). Clinical data was collected from patient records. Results COX2 expression was found in 78% (109/139) of the bAVMs and localized to the vessels’ lumen or medial layer in 70% (95/135) of the bAVMs. Receptors for prostaglandin E2, a COX2-derived mediator of vascular remodeling, were found in the endothelial and smooth muscle cells and perivascular inflammatory cells of bAVMs. COX2 was expressed by infiltrating inflammatory cells and correlated with the extent of inflammation (r = .231, p = .007, Spearman rank correlation). COX2 expression did not associate with haemorrhage. Conclusion COX2 is induced in bAVMs, and possibly participates in the regulation of vessel wall remodelling and ongoing inflammation. Role of COX2 signalling in the pathobiology and clinical course of bAVMs merits further studies.

Arsenic (As) is a naturally occurring element in the environment that poses significant risks to human health. Several treatment technologies have been successfully used in the treatment of As-contaminated waters. However, limited literature has explored advanced electrocoagulation (EC) processes for As removal. The present study evaluates the As removal performance of electrocoagulation, electrochemical peroxidation (ECP), and photo-assisted electrochemical peroxidation (PECP) technologies at circumneutral pH using electroactive iron electrodes. The influence of As speciation and the role of oxidants in As removal were investigated. We have identified the ECP process to be a promising alternative for the conventional EC with around 4-fold increase in arsenic removal capacity at a competitive cost of 0.0060 $/m3. Results also indicated that the rate of As(III) oxidation at the outset of electrochemical treatment dictates the extent of As removal. Both ECP and PECP processes reached greater than 96% As(III) conversion at 1 C/L and achieved 86% and 96% As removal at 5 C/L, respectively. Finally, the mechanism of As(III) oxidation was evaluated, and results showed that Fe(IV) is the intermediate oxidant generated in advanced EC processes, and the contribution of •OH brought by UV irradiation is insignificant.

Although the issue of corporate culture has been taken over and addressed in the literature from various perspectives, there are very few researchers about the role of leadership and motivation in it, respectively very few researchers have addressed them as important components of the international company’s corporate culture. The present paper aims to point out that leadership and motivation can be perceived as important aspects of the international company’s corporate culture. The object of the investigation was an international company (situated in Italy) and its five subsidiaries (situated in Italy, Czech Republic, Germany, and Turkey). As the main research method, there was chosen the method of the questionnaire survey, which was attempted by all the company’s employees (totally 270 respondents). The questionnaire was divided into three separate, but logically related parts—leadership, motivation, and corporate culture, and submitted to two groups of respondents—the company’s management and its employees. In total 11 hypotheses were formulated and further evaluated by the methods of Pearson Chi-square Test, Fisher’s Exact Test, Cramer’s V coefficient, Kendall rank correlation coefficient, Eta coefficient, Spearman coefficient, Mann–Whitney U test and Wilcoxon W statistics, Kruskal–Wallis test, and Friedman’s test. The results of the research have proven that leadership and motivation are important parts of the corporate culture.

Abstract. Background: Reporting on suicide can elicit an increase in suicides, a phenomenon termed the “Werther effect.” The name can be traced back to an alleged spike in suicides after the publication of Goethe's novel The Sorrows of Young Werther in 1774, in which the protagonist Werther dies by suicide. Aims: Acknowledging the importance and primacy of systematic ecological and individual-level studies, we provide a historical single-case report of the suicide of a “late arrival of the Werther epidemic,” as the death was headlined in a news report in 1927. Method: Archival research on tenor Paul Vidal's suicide was conducted. Results: Vidal reconstructed the scene of the final act of the opera Werther in his apartment and died by a gunshot, as did Werther. Limitations: Causal interpretations must be made with caution. Conclusion: Striking similarities between Werther's and Vidal's deaths support the idea of strong identification with the fictional narrative and suggest causal effects. Considering the repeated high level of immersiveness and the intense emotions of opera performances, it is likely that performing the role of Werther increases identification processes, contributing to detrimental effects. The lack of knowledge regarding the role of fictional suicide stories on artists' suicides is discussed.

Tuberculosis, caused by Mycobacterium tuberculosis, remains a leading cause of morbidity and mortality globally, with nearly 10.4 million new cases of incidence and over 1.7 million deaths annually. Drug-resistant M. tuberculosis strains, especially multidrug-resistant or extensively drug-resistant strains, have further intensified the problem associated with tuberculosis control. Host-directed therapy is a promising alternative for tuberculosis control. IL-32 is increasingly recognized as an important host molecule against tuberculosis. In this review, we highlight the proinflammatory properties of IL-32 and the mode of action of IL-32 in mycobacterial infections to inspire the development of novel immunity-based countermeasures and host-directed therapies against tuberculosis.
