Nucleation stage in supersaturated vapor with inhomogeneities due to nonstationary diffusion onto growing droplets

An analytical description of nucleation stage in a supersaturated vapor with instantly created supersaturation is given with taking into account the vapor concentration inhomogeneities arising as a result of depletion due to non-stationary diffusion onto growing droplets. This description suggests that the intensity of the nucleation of new droplets is suppressed in spherical diffusion regions of a certain size surrounding previously nucleated droplets, and remains at the initial level in the remaining volume of the vapor-gas medium. The value of volume excluded from nucleation depends on the explicit form of the vapor concentration profile in the space around the growing droplet, and we use for that the unsteady self-similar solution of time-dependent diffusion equation with a convective term describing the flow of the gas-vapor mixture caused by moving surface of single growing droplet. The main characteristics of the phase transition at the end of the nucleation stage are found and compared with those in the theory of nucleation with homogeneous vapor consumption (the theory of mean-field vapor supersaturation).Comment: This work was presented on Research Workshop 'Nucleation Theory and Applications' (Dubna, Russia) in 2013.

Fostering Bibliodiversity in Scholarly Communications: A Call for Action!

Diversity is an important characteristic of any healthy ecosystem, including scholarly communications. Diversity in services and platforms, funding mechanisms, and evaluation measures will allow the scholarly communication system to accommodate the different workflows, languages, publication outputs, and research topics that support the needs and epistemic pluralism of different research communities. In addition, diversity reduces the risk of vendor lock-in, which inevitably leads to monopoly, monoculture, and high prices. Bibliodiversity has been in steady decline for decades.1 Far from promoting diversity, the dominant “ecosystem” of scholarly publishing today increasingly resembles what Vandana Shiva (1993) has called the “monocultures of the mind”2, characterized by the homogenization of publication formats and outlets that are largely owned by a small number of multinational publishers who are far more interested in profit maximization than the health of the system. Yet, a diverse scholarly communications system is essential for addressing the complex challenges we face. As we transition to open access and open science, there is an opportunity to reverse this decline and foster greater diversity in scholarly communications; what the Jussieu Call refers to as bibliodiversity3. Bibliodiversity, by its nature, cannot be pursued through a single, unified approach, however it does require strong coordination in order to avoid a fragmented and siloed ecosystem. Building on the principles outlined in the Jussieu Call, this paper explores the current state of diversity in scholarly communications, and issues a call for action, specifying what each community can do individually and collectively to support greater bibliodiversity in a more intentional fashion

Job Recruitment & Retention in Rural Ontario: A Model of Physician Recruitment, Applied to the Recruitment of Local Government Professionals in Bruce County

There are many differences between medical practices in urban and rural settings. As it relates to the recruitment of physicians, there is substantially more emphasis placed on the significance of physicians within rural municipalities and a number of resources are employed to recruit physicians to those areas. Similarly, rural local government organizations experience many of the same fundamental differences compared to urban local government organizations, but lack many of the resources necessary to recruit professionals to rural areas. As a result, rural municipalities struggle to fill vacancies and often lack the required knowledge and skills that are necessary to fulfill their professional responsibilities. This research study explores the reasons why physicians and medical practitioners choose to practice in small, rural municipalities, and the extent to which physician recruitment specialists go to in order to recruit physicians to these communities. A review of the literature was used to analyze the practices associated with rural physician recruitment, and a number of recommendations were formulated based on these practices. The literature review identified factors that contribute to both the recruitment and retention of physicians in rural municipalities. These findings are applicable in the context of recruitment to rural local government organizations and assist in providing recommendations to improve current recruitment practices and hiring standards to ensure qualified professionals and senior managers are filling important municipal roles. Through the analysis was confirmed that many of the factors that impact recruitment of physicians to rural municipalities are similar to those factors that constrain local government organizations. There are many opportunities that are available to local government organizations including varying methods used to recruit suitable candidates in addition to benefits that may be able to entice qualified professionals to consider employment in small, rural municipalities

FOSTER D2.1 - Technical protocol for rich metadata categorization and content classification

FOSTER aims to set in place sustainable mechanisms for EU researchers to FOSTER OPEN SCIENCE in their daily workflow, supporting researchers optimizing their research visibility and impact and the adoption of EU open access policies in line with the EU objectives on Responsible Research & Innovation.<p></p> More specifically, the FOSTER objectives are to:<p></p> • Support different stakeholders, especially young researchers, in adopting open access in the context of the European Research Area (ERA) and in complying with the open access policies and rules of participation set out for Horizon 2020;<p></p> • Integrate open access principles and practice in the current research workflow by targeting the young researcher training environment;<p></p> • Strengthen the institutional training capacity to foster compliance with the open access policies of the ERA and Horizon 2020 (beyond the FOSTER project); <p></p> • Facilitate the adoption, reinforcement and implementation of open access policies from other European funders, in line with the EC’s recommendation, in partnership with PASTEUR4OA project.<p></p> As stated in the project Description of Work (DoW) these objectives will be pursued and achieved through the combination of 3 main activities: content identification, repacking and creation; creation of the FOSTER Portal; delivery of training.<p></p> The core activity of the Task T2.1 will be to define a basic quality control protocol for content, and map available content by target group, and content type in parallel with WP3 Task 3.1.<p></p> Training materials include the full range of classical (structured presentation slides) and multi-media content (short videos, interactive e-books, ) that clearly and succinctly frames a problem and offers a working solution, in support of the learning objectives of each target group, and the range of learning options to be used in WP4 (elearning, blended learning, self-learning).<p></p> The map of existing content metadata will be delivered to WP3 for best choice of system requirements for continuous and sustainable content aggregation, enhancement and content delivery via “Tasks 3.2 e-Learning Portal” and “Task 3.4 Content Upload”. The resulting content compilation will be tailored to each Target Group and delivered to WP4
