Synthesis of silacyclopent-2-en-4-ols via intramolecular [2 + 2] photocycloaddition of benzoyl(allyl)silanes
2019
Organosilicon compounds are versatile units with a wide range of uses from medicinal chemistry to the field of organic electronics. An unprecedented method for the synthesis of novel diaryl-substituted silacyclopentenols via blue-light promoted intramolecular [2 + 2] photocycloaddition of acyl silanes is herein disclosed. Additionally, the present findings demonstrate the influence of the olefin substituents in controlling the regioselectivity of the intramolecular Paterno–Buchi reaction, providing silacycles different from previously reported ones. The high degree of functionalization of these compounds makes them attractive precursors to other synthetically challenging silacyclopentanes.
Structural, electronic, and electrical properties of an Undoped n-Type CdO thin film with high electron concentration
2014
Transparent conducting metal oxides (TCOs) combine the properties of optical transparency in the visible region with a high electrical conductivity. They are a critical component as the window electrode in liquid crystal and electroluminescent display devices, as well as in many designs of solar cells now under development. Sn-doped In2O3 is currently the most important TCO, but it suffers from some drawbacks. These include the high cost of indium, weak optical absorption in the blue-green region, as well as chemical instability that leads to corrosion phenomena in organic light-emitting devices. Indium tin oxide (ITO) films are also brittle and of relatively low durability. A number of oth…
Crafting messages to fight dishonesty: A field investigation of the effects of social norms and watching eye cues on fare evasion
2021
Abstract The impact of watching eyes cues and descriptive social norm messages on fare evasion was studied in two experiments that were conducted in two railway stations in France. In Study 1, a natural field experiment, passengers were exposed for a two-week period to either a control eye-cues poster or to an experimental eye-cues with a social norm messaging campaign. In Study 2, an artefactual experiment in the field, participants in the experimental train station were asked to participate in a lying task before and after they were exposed to the messaging campaign. The results from both studies suggest that although watching eye cues alone are not effective in a crowded train station, e…
Conflicting vocational identities and careers in the sector of tourism
2004
This article investigates the formation of vocational identities of workers in the sector of tourism in the Czech Republic, Greece and Spain. Major challenges and conflicts shape the sector of tourism as a particular labour space. Emerging issues relate to the need for diversifying the offer of services to face seasonality, strategies of entrepreneurial merging and demands for mobility and flexibility of the workforce. For the individual worker, a complex combination of related factors lead to tensions and contradictions, particularly in terms of changes in work organization, flexibility and how vocational identities of workers are shaped. An active policy for social dialogue and the improv…
Adequate policies and unintended effects in Spanish higher education
2000
Abstract Recent developments in Spanish higher education have been very positive. Universities have become autonomous and are more in tune to regional needs, their internal structure has become flexible, the whole system has become open and accessible, funds have been poured into the system as never before and market forces have started to play a relevant role. Nevertheless, some perverse effects have begun to emerge. We will focus on some of these negative aspects that deserve deeper consideration: the inadequate adaptation to a mass higher education system, and the negative consequences of the collegial model for governing universities and of regionalization.
Flexible employment practices and working time patterns: the potential for and limits of ecological impact
1996
The discussion about the relationship between employment policy and environment policy has been predominantly about the extent to which environmental issues can be brought into industrial relations policy. Environmental problems are perceived as additional factors of influence, which have an impact on job security and working conditions, and which have so far not been adequately taken into account in standards and rules. From the current viewpoint of union representatives, conservation of the environment is being brought into discussion in the form of an "employment policy extended to include the environment". Progress made in this field in recent years is increasingly undermined by radica…
Job attitudes, behaviours and well-being among different types of temporary workers in Europe and Israel
2011
Applying an innovative typology based on preference for temporary em- ployment and perceived employability, the authors empirically examine four types of temporary workers (and a group of permanent workers for comparison). In a sample of 1,300 employees from six countries, they find significant differences between the four types on a broad set of variables - including demographic and job characteristics, attitude and insecurity - but not in life satisfaction and well-being. They conclude with an argument against the equation of temporary employment with low-skilled workers unable to find a permanent job, stressing the valuable implications of more sensitive research for policy-making on fle…
Job insecurity in the younger Spanish workforce: Causes and consequences
2012
Abstract The Spanish labor market is currently an example of a flexible labor market. However, it involves a set of detrimental conditions for its workforce, such as lower employability in the labor market and underemployment (i.e. over-qualification and underemployment in time). In this study, we assume that all these conditions promote higher job instability, which is especially serious for the younger population. Hence, the present study aims to examine, on the one hand, how these specific labor conditions affect younger employees' concerns about job loss or job insecurity and, on the other, how this job insecurity can affect their current job performance and the future development of th…
Hyper-mobile migrant workers and Dutch trade union representation strategies at the Eemshaven construction sites
2016
The EU regulatory regime and employers’ cross-border recruitment practices complicate unions’ ability to represent increasingly diverse and transnationally mobile workers. Even in institutional contexts where the industrial relations structure and labour law are favourable, such as the Netherlands, unions struggle with maintaining labour standards for these workers. This article analyses Dutch union efforts to represent hyper-mobile construction workers at the Eemshaven construction sites. It shows that the nexus of subcontracting, transnational mobility, legal insularity and employer anti-unionism complicate enforcement so that even well-resourced unions can, at best, improve employment c…
Measuring organisational learning capability among the workforce
2007
PurposeThe present study sets out to propose and validate a measurement scale that aims to capture the organisational capability to learn, based on a comprehensive analysis of the facilitating factors for learning. The organisational learning capability scale consists of 14 items grouped into five dimensions: experimentation, risk taking, interaction with the external environment, dialogue, and participative decision making.Design/methodology/approachData were collected from eight Spanish ceramic tile manufacturers. The survey was addressed to shop floor workers. A total of 157 valid questionnaires were obtained, representing a response rate of 61 per cent. Using confirmatory factor analysi…
