UV‐curable systems based on the copolymerisation of a typical acrylic resin with low amount of fluorinated monomers (less than 1 per cent w/w) were prepared. The bulk properties of the films were unchanged, while a strong modification of the surface was obtained, depending on the monomer structure, on its concentration and on the type of substrate.

New acrylic and allylic resins were prepared by functionalising perfluoropolyethers chains, which assured peculiar surface properties. Blends having a different amount of the acrylic and of the allylic systems were cured in air by UV irradiation. The cure of the films was found dependent on the ratio between the two resins; the concentration for the obtaining of a film fully cured in air was determined. On the basis of this concentration, a macromer functionalised with the right amount of both the acrylic group and the allylic one was synthesised.

This study aims to explore the role of Italian women in society and at work during the pandemic. Specifically, it analyses Italian women’s positioning in the work context and in the leadership coordinating the national response to the Covid-19 pandemic.

Inspired by feminist thinking addressing recent debates on women’s livelihoods at the time of Covid-19, the study focusses on Italy’s gendered response to the pandemic and its exclusion of women from decision-making roles in the management of the pandemic and the subsequent post-pandemic socio-economic recovery. Drawing on recent studies and media contributions it provides a thought-provoking analysis embedded in the country’s history and culture.

Despite their high involvement in the daily management of the pandemic, as key workers and family carers, Italian women’s voices have remained unheard and concealed, even in face of movements towards their recognition (#DateciVoce). This study trace this lack of inclusion in the sedimented gender inequalities characteristic of the Italian socio-political-economic context, combined with the effects of Covid-19. This study suggest that the country needs a long overdue and radical shift towards the centring of women and their contributions in work and society.

The study offers insights into the gendered pandemic response of one of the first and worst affected countries. It specifically addresses women’s continued marginalisation in the political arena vis-à-vis their key role in supporting the country’s economy.

The growth of women in management has been argued to offer a route to reduce organizational and social inequality. The purpose of this paper is to explore the careers and experiences of female managers from a variety of organizations operating in the West Midlands region of the UK.

This study is based on 56 interviews conducted with women managers within various sectors. The interviewees also completed pictorial careers maps, which along with interview recordings were analyzed.

The key themes to emerge from this research centre upon the factors that draw women into management (which we term seductive elements) as well as some of the hindering practices that prevent women from progressing. Significantly, we find that managerial careers are associated with gendered assumptions and practices (e.g. facilitating and developing people) which contribute to construct management (done by women) as bounded‐up characteristically with “feminized” behaviours.

The research is based upon a relatively small sample that is multi‐sectorial. Wider studies that increase population size, together with deeper studies that hold sectorial variables constant would further add weight to the findings presented here.

The paper draws attention to the “lived reality” of doing management, which, we argue often, for women in particular involves the reconciliation of contradictions and conflicting pressures. We draw attention to the lack of “alternative models” of organization and highlight the potential for gender‐focus mentoring and management education.

The paper is of value in giving voice to a selection of women managers by allowing them to reflect upon and explore their experience of management. The paper also documents the day‐to‐day reality of women's managerial careers that require the re‐enactment and reproduction of stereotypical gender norms.

The purpose of this paper is to highlight how women managers in Swedish higher education (HE) both support and resist policies about equal representation, and to discuss which factors influenced if, and how, these managers took on the role as change agents for gender equality.

The paper draws on qualitative semi-structured interviews with 22 women in senior academic management positions (vice-chancellors, pro vice-chancellors, deans and pro deans) in ten Swedish HE institutions.

The paper highlights how these women situated themselves in an academic context where gender relations were changing. They supported equal representation policies in their everyday managerial practice and also by accepting management positions that they were nominated and elected to on the basis of such policies. However, they also resisted these policies when they experienced a need to “protect” women from being exploited “in the name of gender equality”.

The paper addresses the call for research on the role of women managers in promoting, or preventing, change towards more gender balanced organizations. The paper builds on a small qualitative study with women only interviews. The study is therefore to be considered as explorative.

The paper makes a contribution to the research literature in the area of gender and change in academic organizations. The findings highlight how policies have different consequences in different settings and that people use their own (different) experiences when interpreting the effects of these policies. The findings thus show the varying impacts equal representation policies can have on women.

The discussion in the paper is situated in a unique empirical context characterized by demographic feminization and organizational restructuring. Most international literature on women in HE and in HE management is based on US or UK contexts. Swedish HE therefore provides an interesting setting. The analysis also addresses the call for more research that takes into account the multifaceted character of HE and that discusses disciplinary differences.

While diversification within organisations is seen by many to be a strategic move, there is conflicting evidence about what makes diverse teams successful. The purpose of this paper is to highlight a range of complex, and in some cases contradictory, research contributions towards several key areas of diversity within teams, and to propose a framework for integrating existing approaches and clarifying inconsistencies in this domain.

A literature review was conducted to explore several key areas of surface and deep-level diversity in teams, with the discussion included in this paper highlighting many of the inconsistencies and complexities associated with this research domain.

This review highlights the need for future research to look at the effects of surface and deep-level diversity simultaneously, over time, across multiple levels and with a broad range of contextual moderators, to examine their impact on a range of outcomes.

In order to account for the complexities within diversity research, the authors propose the use of the job demands-resources (JDR) model which suggests possible explanations for inconsistent findings and bridges the gap between commonly used theoretical perspectives.

Gender-based discrimination (GBD) in the workplace is a worldwide phenomenon. Both developed and developing states face this issue at different levels and magnitudes, though in the latter, it is more prevalent. We explore the overlooked possible root causes of workplace GBD.

Employing qualitative methods, data were collected via semi-structured interviews from 40 women employed in the service sector in Pakistan and the UK. Data underwent thematic analysis by applying the Gioia method.

Using ambivalent sexism theory to underpin our approach, we conclude that educational institutes, especially single-gender ones, could be among the primary reasons for GBD in Pakistani workplaces, but not those in the UK, where it is less prominent. We identify common factors that challenge this theory and point out current social, industrial and economic situations that link with such single-gender education.

This study can help “institutionalize” (establish policy and practice as organizational culture) a discrimination-free workplace and assist relevant stakeholders by facilitating policymakers and government agencies to more deeply understand causality and take corrective and preventative action against GBD.

The findings contribute to the studies of gender discrimination and educational provision by elucidating previously overlooked possible roots of persistent GBD.

The purpose of this paper is to investigate the effects of multi-hydroxymethylated phenol (MHMP) on the properties of moisture-curing polyurethane (PU) resin, especially on the heat resistance.

The MHMPs with various active sites from 2.52 to 3.91 were synthesised and used as a modifier. The bond test (according to the JIS K6806-2003 standard) and thermogravimetric analysis (TGA) were used, respectively, to characterise the bond durability and heat resistance of MHMP-modified PU resin.

The MHMP with various F/P mole ratios had great effects on the properties of resultant PU resins. The increase of active sites of MHMP can improve the water resistance of resin due to the more cross-linking densities, while the decrease of active sites of MHMP can improve heat resistance of resin because more stable benzene ring introduced into the PU backbone.

In cases where heat resistance of the PU resin is of primary concern, the use of MHMP with fewer active sites or a lower F/P ratio is recommended. In other cases where bond durability is focussed, the modifier MHMP shall be synthesised with higher F/P ratio.

MHMP as a modifier can be used to improve the heat resistance of PU resin.

The MHMPs with various hydroxymethyl groups were synthesised and used as modifier of moisture-curing PU resins to improve their heat resistance.

Over the last several years, the range of applications of photopolymerization process has been steadily increasing, especially in areas such as rapid prototyping, UV inks, UV coats and orthodontic applications. In spite of this, there are still several challenges to be overcome when the application concerns materials with thick layers. In this context, the main goal of this work is to outline a scheme to optimize the process of photopolymerizarion for thick layers, identifying its differences in relation to those applicable for thin layers.

For this research, the authors have applied multivariable analysis methods which allow the identification of principal conclusions, based on analytical and experimental results. For analytical analysis, the authors applied numerical optimization for multivariables, while experimental analysis was done based on design of experiments. Both the analyses were based on methyl methacrylate as monomer and Omnirad 2500 as photoinitiator, with the adjustable variables being initiator concentration; power of light source; light wave length; and thickness of layer. The range of values chosen for initiator concentration was between 1 and 10 per cent, while for light power, the range was 5‐9 W. For light wave length, the authors selected 325 and 400 nm as limits for their study and 0.12 and 4 mm as the range for thickness of layers. For the analytical approach of their study, it was possible to identify optimum conditions for curing thick layers, besides looking at optimum condition at each step along the varying thickness. On the other hand, in the experimental approach, the authors just considered the initiator concentration and thickness as variables, applying gravimetric and photometric analysis to determine the conversion curve of material.

In conclusion based on these studies, it was possible to identify the influence of thickness and initiator concentration as function of penetration depth, polymerization rate and homogeneity of material, in addition to determining the effect of light power and light wave length over the process. As a result of these studies, it was possible to identify situations wherein the material will possibly undergo a high degree shrinkage in addition to showing consequences of high quantity of initiator. On the other hand, low concentration of initiator is shown to provide more homogeneous solution besides being more suitable for deep layers. It was also possible to compare analytical and experimental results, making it possible to predict the behaviour of material for other conditions.

The main value of this work is to show the possibility of optimizing photopolymerizable systems through an analytical approach. In addition, it emphasized the viability of the application of UV curable material for producing moulded parts.

This article describes the experiences of a librarian in a tutor/facilitator role immersed within a mainstream problem‐based learning (PBL) curriculum at the University of New Mexico School of Medicine. The role of tutor might be a suitable non‐traditional role for librarians. Tutoring turns out to be an entirely different role from traditional teaching. This tutor role requires practicing reciprocity, patience and commitment. This role has provided a profound understanding of the curriculum as it relates to library and informatics services, earned respect from non‐librarians, and prompted one to re‐think the integrated model of library instruction. Librarians willing to meet the challenges of tutoring can succeed in this non‐traditional role with the many associated benefits.
