How long do top scientists maintain their stardom? An analysis by region, gender and discipline: evidence from Italy
We investigate the question of how long top scientists retain their stardom.
We observe the research performance of all Italian professors in the sciences
over three consecutive four-year periods, between 2001 and 2012. The top
scientists of the first period are identified on the basis of research
productivity, and their performance is then tracked through time. The analyses
demonstrate that more than a third of the nation's top scientists maintain this
status over the three consecutive periods, with higher shares occurring in the
life sciences and lower ones in engineering. Compared to males, females are
less likely to maintain top status. There are also regional differences, among
which top status is less likely to survive in southern Italy than in the north.
Finally we investigate the longevity of unproductive professors, and then check
whether the career progress of the top and unproductive scientists is aligned
with their respective performances. The results appear to have implications for
national policies on academic recruitment and advancement
The glass ceiling : is it a state of mind?
Much is written in the literature and press about women having to break through the glass ceiling, but is there indeed any truth in this theory? For some women, working their way up the promotion ladder can be a challenge, but is it really as difficult as it is perceived? It would be naïve to think that all women are as ambitious as to want to break through the glass ceiling, and indeed in certain categories of employment such as advertising and marketing, they do appear to have made their mark, but science, engineering and technology, do not seem to attract females in the same numbers. We would argue that this lack of advancement is not necessarily due to a lack of opportunity. This paper addresses the role of women in science, engineering, and technology, assessing the support mechanisms offered to them to succeed in their chosen occupations. The investigation identifies factors that have led to women achieving senior levels in higher education, business, and government in the UK, thus making it through the glass ceiling. The methodology undertaken in this study includes, desk-based research, analysis of surveys, observations from literature search and surveys, and interviews/case studies of a number of prominent and internationally successful women; and final conclusions. All comprise the three components of the Triple Helix - influence of government through legislation, uptake in academia, and attendant support mechanisms, and impact in industry
Factors Contributing to Participation in Web-based Surveys among Italian University Graduates
An established yearly survey aimed at monitoring the employment opportunities of Italian graduates, traditionally carried out with Cati methods, has been integrated during the last few years with Cawi. Cawi has become increasingly crucial due to the high number of graduates involved in the survey, which has mandated a reduction in fieldwork duration and unit costs. Although the seven Cawi surveys used here have different substantive and methodological characteristics, preliminary analysis reveals a common trend: the utmost participation is observed during the first few days immediately following initiation of fieldwork and, to a lesser degree, the delivery of follow-up reminders. Web respondents comprise a self-selected subgroup of the target population, having better academic performance and greater computer skills. A Cox regression model estimating response probability (or response time) shows, besides the obvious effects of certain personal and survey design characteristics, that faster response times are expressed by graduates in science or engineering and reporting good computer skills, whereas the fields of medicine/health and defence/security and no computer skills give rise to lower response probability. Ways to use these findings for fine-tuning data collection are discussed.Cawi surveys, Response rate, University graduates,Cox regression
The nature and trends of agricultural research development in Africa : an informetric study
The study recognizes Agriculture as the mainstay activity of most economies in Africa and analyses research nature and trends in the discipline by using descriptive informetrics and focusing on seven indicators, by using the AGRICOLA and ISI-E databases from 1991 to 2005. We observed that research output in the discipline is much higher in South Africa and Kenya, and research collaboration is greater than non-collaborative research output and collaboration is less among African countries. The most popular research domains were found to exist in environmental science, soil science, plant/crop production and [agricultural] economics. Helpful conclusions and recommendations for an Agricultural policy, capacity and research orientation have been made
Physical and mental health of university staff during the Covid-19 pandemic
The 2020 Covid-19 pandemic caused a sudden and massive change in work organizations. One of the major consequences of the crisis was the acceleration towards teleworking, through the specific phenomenon of Mandatory Work From Home: the situations in which workers overnight found themselves to work seven days a week from their home environment, constantly online, often without adequate equipment and little to no preparation. Different workers reacted in different way to this important change, depending on age, gender, family characteristics and other impacting factors. Mandatory work from home and these other variables impacted employees’ physical and mental health, triggering or increasing symptoms of overwork and emotional exhaustion among others. This paper contributes to the literature on the impact of the pandemic on workers’ health by giving an overview of the effects of MWFH on university staff, using Politecnico di Torino as a case study
The structure of the Arts & Humanities Citation Index: A mapping on the basis of aggregated citations among 1,157 journals
Using the Arts & Humanities Citation Index (A&HCI) 2008, we apply mapping
techniques previously developed for mapping journal structures in the Science
and Social Science Citation Indices. Citation relations among the 110,718
records were aggregated at the level of 1,157 journals specific to the A&HCI,
and the journal structures are questioned on whether a cognitive structure can
be reconstructed and visualized. Both cosine-normalization (bottom up) and
factor analysis (top down) suggest a division into approximately twelve
subsets. The relations among these subsets are explored using various
visualization techniques. However, we were not able to retrieve this structure
using the ISI Subject Categories, including the 25 categories which are
specific to the A&HCI. We discuss options for validation such as against the
categories of the Humanities Indicators of the American Academy of Arts and
Sciences, the panel structure of the European Reference Index for the
Humanities (ERIH), and compare our results with the curriculum organization of
the Humanities Section of the College of Letters and Sciences of UCLA as an
example of institutional organization
