Impact and effectiveness of risk mitigation strategies on the insurability of nanomaterial production: evidences from industrial case studies.
2014
Workers involved in producing nanomaterials or using nanomaterials in manufacturing plants are likely to have earlier and higher exposure to manufactured/engineered nanomaterials (ENM) than the general population. This is because both the volume handled and the probability of the effluence of ‘free’ nanoparticles from the handled volume are much higher during a production process than at any other stage in the lifecycle of nanomaterials and nanotechnology‐enabled products. Risk assessment (RA) techniques using control banding (CB) as a framework for risk transfer represents a robust theory but further progress on implementing the model is required so that risk can be transferred to insuranc…
Appetizer or main dish? Explaining the use of Facebook news posts as a substitute for other news sources
2019
An increasing number of, especially younger, users use Facebook as their primary source for news about political and societal issues. At the same time, research suggests that Facebook use contributes to societal knowledge gaps. Against this background, we investigate the antecedents of using Facebook as a substitute for other news sources. We argue that exposure to news posts on Facebook increases the feeling of being well-informed, regardless of actual knowledge acquisition. This might lead users, especially those with a low need for cognition (NfC), to use Facebook as a substitute for other news sources. We test these assumptions with an online survey (n=390) of German Internet users. Res…
A CAPWAP Architecture for Automatic Frequency Planning in WLAN
2007
Recently, the impressive success of the IEEE 802.11 WLAN technology has dramatically changed the role of the wireless connectivity provisioning. Born as a wireless extension of small office or home networks, todays the WLANs are getting more and more popular as a large, even metropolitan, area networks. The deployment of large-scale WLANs has some critical issues, because of the lack of coordinated management functionalities among the network nodes. In this paper we briefly describe the CAPWAP architectural solution, for centralizing some control and maintenance functionalities in large scale WLAN, by guaranteeing the interoperability between network nodes provided by different vendors. We …
On the current neuroenhancement use of transcranial direct current stimulation by healthy individuals—A non-fictional snap-shot: Commentary on Lapent…
2014
This commentary examines the pros and cons of the fictitious enhancement scenarios used in Lapenta et al. 2014. Then it gives a non-fictional impression of the current self-enhancement use of transcranial direct current stimulation (tDCS) by healthy individuals and discusses the ethical issues involved.
Social Suffering and an Approach to Professionals’ Burnout
2014
Individual and social problems require the assistance of professionals who are accustomed to work with “suffering” on daily basis. Psychologists, physicians, and social workers step into this role helping alleviate the suffering and improve the quality of life of their patients and clients. But, inevitably, they experience suffering as they address others’ problems. Their own well-being and quality of life may be reduced by their work in helping. We interviewed Argentinean professionals about their experience of patient, personal, and suffering conditions in order to determine the level of transference and turn to the practice of Yoga as a possible physical and psychological approach to med…
Research of genetic and molecular determinants involved in the nodulated root system architecture of legumes and contributing to improved nitrogen nu…
2016
Grain legume pulse crops are of great interest to allow a production of seeds high nutritional value without any contribution of nitrate fertilizer. The nitrogen nutrition of legumes depends indeed mainly on the fixation in nodules of atmospheric dinitrogen through the plant-rhizobium symbiosis, and to a lesser extent, absorption by roots of soil mineral nitrogen.A better understanding has been obtained on the genetic control of the development of roots and nodules and on their impact on nitrogen nutrition. High genetic variability of these characters has been detected, and the existence of genetic correlations between them demonstrated. A quantitative genetic approach has identified severa…
Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo
2022
Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…
Early stage screening of breast cancer using electrochemical biomarker detection
2017
Recently researchers have driven their attention in the development of biosensors for breast cancer detection using different biomarkers. This review reports a systematic study of the usefulness of marker-based electrochemical biosensors in breast cancer and its early diagnosis. Also, various types of electro-analytical methods for early stage screening of breast cancer were discussed. The emphasis is placed on immune-, geno- cyto- and enzyme-biosensing strategies. In addition, the advantages offered by some nano-materials in detection of breast cancer biomarkers are illustrated with representative recent examples that highlight the scientific interest in widening the use of new materials/m…
The Effect of Overeducation on Job Content Innovation and Career-Enhancing Strategies Among Young Spanish Employees
2009
The increase of education in younger people and the relative scarcity of qualified jobs available for them make the overeducation of young workers a social issue. We explored the relationships between overeducation and extra-role behaviors (job content innovation and career-enhancing strategies) as well as the direct and moderating role of personal initiative and intrinsic work values in these relationships. We collected data from a sample of 638 young Spanish employees. As expected, there were negative relationships between overeducation and content innovation and career-enhancing strategies. Personal initiative and intrinsic work values related positively to extra-role behaviors. Moreove…
Training During the COVID-19 Lockdown: Knowledge, Beliefs, and Practices of 12,526 Athletes from 142 Countries and Six Continents
2021
Abstract Objective Our objective was to explore the training-related knowledge, beliefs, and practices of athletes and the influence of lockdowns in response to the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods Athletes (n = 12,526, comprising 13% world class, 21% international, 36% national, 24% state, and 6% recreational) completed an online survey that was available from 17 May to 5 July 2020 and explored their training behaviors (training knowledge, beliefs/attitudes, and practices), including specific questions on their training intensity, frequency, and session duration before and during lockdown (March–Jun…
