Do Women Prefer More Complex Music around Ovulation?
2012
The evolutionary origins of music are much debated. One theory holds that the ability to produce complex musical sounds might reflect qualities that are relevant in mate choice contexts and hence, that music is functionally analogous to the sexually-selected acoustic displays of some animals. If so, women may be expected to show heightened preferences for more complex music when they are most fertile. Here, we used computer-generated musical pieces and ovulation predictor kits to test this hypothesis. Our results indicate that women prefer more complex music in general; however, we found no evidence that their preference for more complex music increased around ovulation. Consequently, our f…
Human error contribution to accidents in the manufacturing sector: A structured approach to evaluate the interdependence among performance shaping fa…
2023
Since the 1970s, Human Reliability Analysis (HRA) methods have received a great interest for the quantification of the Human Error Probability (HEP) in Nuclear Power Plants (NPPs). To this purpose, the second-generation HRA methods consider contextual and cognitive factors - named Performance Shaping Factors (PSFs) - that may influence the workers’ performance during tasks execution. Despite the recent extension of HRA methods to different fields, only few studies refer to the manufacturing sector. In addition, the majority of contributions assume the independence among PSFs, which may result in an over or under estimation of HEP. Therefore, the present paper focuses on the manufacturing se…
Effect of Substituents at Imide Positions on the Laser Performance of 1,7-Bay-Substituted Perylenediimide Dyes
2021
Perylenediimide (PDI) compounds with no substituents in their core are widely used as the active units of thin-film organic lasers. Recently, bay-substituted PDIs (b-PDIs) bearing two sterically hindering diphenylphenoxy groups at the 1,7-bay positions have received great attention because they show red-shifted emission with respect to bay-unsubstituted PDIs, while maintaining high photoluminescence (PL) quantum yields and low amplified spontaneous emission (ASE) thresholds even at high doping rates. However, their ASE photostability is relatively low compared to that of state-of-the-art PDIs. Thus, the design of b-PDIs with improved ASE photostability remains a challenge. Here, the synthes…
Qualitative study about group music therapy experience of young musicians dealing with music performance anxiety
2015
Few studies have looked or presented the meaning of music performance anxiety from the viewpoint of young musician´s. Whereas most of the studies conducted were quantitative, this study used qualitative approach of phenomenology. The aim of this study was to investigate the experience of young musicians dealing with higher amount of music performance anxiety in clinical music therapy group. The study addressed questions about the role of the group, shared experiences in music and the role of free discussions in therapy. Free-flow musical improvisation was the most frequently used clinical technique. Five young musicians took part of 12-weekly group therapy sessions during 5 month period. Ba…
Player performance, satisfaction, and video game enjoyment
2009
An experiment (N = 74) was conducted to investigate the impact of game difficulty and player performance on game enjoyment. Participants played a First Person Shooter game with systematically varied levels of difficulty. Satisfaction with performance and game enjoyment were assessed after playing. Results are not fully in line with predictions derived from flow and attribution theory and suggest players to (1) change their view on their own performance with its implications for enjoyment with increasing game experience and (2) to switch strategically between different sources of fun, thus maintaining a (somewhat) positive experience even when performance-based enjoyment is low.
Gender and Sexuality. Rights, Language and Performativity
2012
The book engages critically with two main aspects of the socio-cultural construction of gender and sexuality. The first section of the volume, Sexual Rights, is socio-political, and includes both the problem of the recognition of rights for all individuals, especially LGBTQI (lesbian, gay, bisexual, transsexual, queer and intersexual) subjects, and the struggle to combat discrimination, that entails an analysis of and an opposition to homophobic discourses and actions. The second section of the volume, Media, Literature and Performativity, involves a theoretical elaboration of discursive and literary strategies that relate or can be applied to gendered and sexed identities. These two sphere…
Gender differences in Italian STEM degree courses: a discrete-time competing-risks model
2020
In this paper, we highlight possible gender differences in performance of students attending Italian university STEM degree courses, controlling for sociodemographic and territorial variables.We used the micro-data from the Italian Ministry of Education, Universities and Research database of the 2011-12 freshmen cohort enrolled at an Italian bachelor university degree course. The analysis was dealt with by fitting a discrete-time competing-risks model. Bachelor degree graduation, dropout, and change to non-STEM courses were considered as competing events. The aim is to highlight gender gaps in the student performance, and the STEM courses where this gap is more critical.
Agents of change: Women in top management and corporate environmental performance
2020
International audience; We analyze the influence of gender diversity in top management on the environmental performance of French firms. Consistent with gender socialization theory, which posits that women are raised from childhood to be more nurturing and compassionate for others, we find that firms with more women in top management exhibit higher environmental performance. This result extends those already reported in the literature regarding the effect of gender diversity at board level. We also show that women in top management are associated with several key indicators such as development of eco‐friendly products and commitment to resource reduction. Furthermore, we find that the influ…
Gender diversity and governance: Analysis of Italian listed companies
2020
In recent years, many countries have adopted different legislative and self-regulatory initiatives to be able to tackle the problem of the underrepresentation of women on boards. Also, Italy with Law No. 120/2011 introduced the gender issue adopting the normative that 1/3 of the elected members would be women. In this job, a primary aim was to study over the period 2016/2018 the impact of female presence on boards of 50 companies listed on the Italian Stock Exchange. In depth, our results confirm that Italian Law has produced significant effects on the composition of the corporate board. The result of our study shows that women positively influence corporate performance, this is perfectly i…
Hemocyanin subunit organization of the gastropod Rapana thomasiana
1999
Abstract RtH1 and RtH2, the two hemocyanin isoforms of the prosobranch gastropod Rapana thomasiana, have been purified by anion-exchange chromatography and studied by SDS–PAGE and immunoelectrophoresis. Both subunit types are built up of eight functional units (FUs). Under reducing conditions subunit RtH2 splits into two fragments, RtH2- a – f and RtH2- gh, suggesting the presence of a disulfide bridge between FU2- f and FU2- g. By proteolytic cleavage of the subunits into three-, two-, and single-FU fragments, purification of fragments by HPLC, N-terminal sequencing of the peptides, and crossed-line immunoelectrophoresis, FUs- a – h of RtH2 and FU- a, FU- d, FU- e, and FU- f of RtH1 were i…
