No full textGoel′s Teflon sponge internal shunt for anterior spinal arachnoid cyst
No full textWe report a case of a 6-year-old boy who presented with progressive quadriparesis and bowel-bladder incontinence. Magnetic resonance imaging (MRI) of the spine showed anteriorly located arachnoid cyst in the cervicodorsal region. Following marsupialization of the cyst, an internal Teflon sponge shunt (Goel′s shunt) was done that extended from the cyst cavity to the subarchnoid space. The patient improved dramatically in his symptoms. The physical nature of the teflon sponge and its usefulness as an internal shunt are discussed
Analysis of social performance and board of directors in family firms: evidence from quoted Italian companies
No full textThe determinants of women's involvement in top management teams: Opportunities or obstacles for family- controlled firms?
No full textAlthough the contribution of TMTs’ diversity, and especially of gender diversity, to firm performance is increasingly acknowledged, the context of family firms is virtually unexplored and the few gender studies available in the family business field focus on female family members. This study is the first to investigate the impact of family nature (measured by family ownership and family CEOs) and on female CEOS on gender diversity in TMTs, as well as to look at gender diversity in terms of both family and non-family women’s presence. Results of a survey based on a representative sample of medium and large Italian family-controlled firms show that: 1) family ownership positively predicts presence of women within TMTs in general, and especially presence of non-family women; 2) family CEOs and female CEOs positively predict the presence of family women within the TMTs; 3) family CEOs negatively predict the presence of non-family women in TMTs. In summation, the family nature of the firm seems influence gender diversity, but to the main benefit of family women, and the same happens with presence of female CEOs (who almost all resulted to belong to the owning family). This integrates upper echelon and diversity literature streams with family-firm specific evidence. A contribution is also offered to family business literature, as survey results help clarify the ambivalence that has emerged so far about owning families and women as possible determinants of female presence in executive positions. Implications for further studies and family firms’ practice are highlighted as well
Causes of Corruption in Russia: A Disaggregated Analysis
No full textThis paper examines determinants of corruption across Russian regions. Key contributions include: (i) a formal study of economic corruption determinants across Russian regions; (ii) comparisons of determinants of perceived corruption versus those of actual corruption; and (iii) studying the influence of market competition and other factors on corruption. The results show that economic prosperity, population, market competition and urbanization are significant determinants of Russian corruption. The use of alternative corruption measures reveals that economic prosperity and population have a largely similar impact on corruption perceptions and corruption incidence. However, there are significant differences in the effects of competition and urbanization.corruption perceptions; corruption incidence; Russia; government; competition
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Death takes no bribes: Impact of perceived corruption on the effectiveness of non-pharmaceutical interventions at combating COVID-19
No full textCorruption is considered in the literature as an activity with several externalities and spillover effects. Adding to the recent research on the corruption-COVID-19 nexus, we study the impact of corruption on coronavirus cases. High perceived levels of corruption have been proven to lead to lower institutional trust, and hence possibly to lower levels of citizen compliance with non-pharmaceutical interventions (NPIs), such as lockdowns, imposed by the authorities during the first wave of the pandemic to reduce the spread of coronavirus. Applying quantitative analysis with the use of hybrid models, we find that in countries with higher levels of perceived corruption, across alternative corruption measures, more COVID-19 cases are observed, ceteris paribus. This suggests that corruption has a detrimental effect on the spread of COVID-19, and that countries experiencing higher levels of corruption should pay extra attention when implementing NPIs
