Building communities, bridging divides: Community technology centers and social capital

This paper explores the use of community technology centers (CTCs) by U.S. adults. In this context, CTCs are broadly defined as public, not for profit facilities where individuals can access the internet and information communication technologies, the most common of which are public libraries. Furthermore, CTCs are a junction where technology usage and community participation can occur concurrently. Two rounds of data collection using Amazon Mechanical Turk (n = 585) and a Qualtrics Survey Panel (n = 330) were used to develop a unique measure of social capital generated at CTCs. Through multiple regression analyses, this study identifies that the activities completed at CTCs but not the frequency of attendance are associated with higher levels of community technology center social capital (CTCSC), or rather the feelings of trust and reciprocity captured by our measure

Rationale and design of Ferinject® Assessment in patients with IRon deficiency and chronic Heart Failure (FAIR-HF) study: a randomized, placebo-controlled study of intravenous iron supplementation in patients with and without anaemia

Iron deficiency (ID) and anaemia are common in patients with chronic heart failure (CHF). The presence of anaemia is associated with increased morbidity and mortality in CHF, and ID is a major reason for the development of anaemia. Preliminary studies using intravenous (i.v.) iron supplementation alone in patients with CHF and ID have shown improvements in symptom status. FAIR-HF (Clinical Trials.gov NCT00520780) was designed to determine the effect of i.v. iron repletion therapy using ferric carboxymaltose on self-reported patient global assessment (PGA) and New York Heart Association (NYHA) in patients with CHF and ID. This is a multi-centre, randomized, double-blind, placebo-controlled study recruiting ambulatory patients with symptomatic CHF with LVEF < 40% (NYHA II) or < 45% (NYHA III), ID [ferritin < 100 ng/mL or ferritin 100-300 ng/mL when transferrin saturation (TSAT) < 20%], and haemoglobin 9.5-13.5 g/dL. Patients were randomized in a 2:1 ratio to receive ferric carboxymaltose (Ferinject((R))) 200 mg iron i.v. or saline i.v. weekly until iron repletion (correction phase), then monthly until Week 24 (maintenance phase). Primary endpoints are (i) self-reported PGA at Week 24 and (ii) NYHA class at Week 24, adjusted for baseline NYHA class. This study will provide evidence on the efficacy and safety of iron repletion with ferric carboxymaltose in CHF patients with ID with and without anaemia

Women\u27s groups and COVID-19: An evidence review on savings groups in Africa

This paper presents emerging evidence from studies in diverse contexts in sub-Saharan Africa —with a deep dive into Nigeria and Uganda—on how COVID-19 has affected women’s groups and how these groups have helped mitigate the gendered effects of the pandemic’s and the associated policy responses’ consequences up until April 2021. The synthesis presents evidence that savings groups found ways to continue operating, provided leadership opportunities for women during the pandemic, and mitigated some of the negative economic consequences of COVID-19 on individual savings group members. Savings, credit, and group support from other members all likely contributed to the ability of groups to positively affect women’s group member’s resilience during COVID-19. However, savings groups themselves often faced financial challenges because of decreased savings, which sometimes resulted in the depletion of group assets. These findings are consistent with a recent evidence synthesis on how past covariate shocks affected women’s groups and their members. We conclude the paper by presenting various policy recommendations to enable savings groups to achieve improvements in women’s empowerment and economic outcomes and research recommendations to address some of the current evidence-gaps on how COVID-19 is affecting women’s groups and their members

Local Economic Impacts of Investments in Community Technology Centers: An Empirical Investigation

Although community technology centers (CTCs) provide a host of services that may have economic consequences, few studies have attempted to empirically assess the impact of CTCs on local communities. Controlling for broadband availability and demographics, this study found that there is a small but positive and significant impact of CTC quality on median household income, at the county level. In addition to bridging the digital divide for disadvantaged populations, our research shows that there are also quantifiable economic benefits from CTC investments

A Melting Pot of Knowledge: A case study exploring willingness and barriers to knowledge sharing and learning among junior and senior preschool teachers in the public sector

Aim: This thesis aims to develop a deeper understanding of how junior and senior preschool teachers engage in knowledge sharing and learning in a public sector organisation as well as how their knowledge sharing and learning behaviour is being challenged. Literature Review: Our literature review focuses on knowledge and knowledge sharing and relates it specifically to the public sector which corresponds to our case organisation. We also discuss literature on willingness and barriers to knowledge sharing and learning, considering differences related to various age and experience levels. Methodology: By conducting 13 semi-structured interviews with 4 junior and 7 senior preschool teachers as well as 2 superiors we followed a qualitative case study with an interpretive tradition and an abductive research approach. Complementary data were obtained through document analysis of 3 internal documents of our case organisation. Findings: Public sector and teaching profession contexts influence the motivation of preschool teachers and their willingness to share knowledge and learn. In relation to the latter, the preschool’s values, and the employees’ identification also play an important role. Regarding barriers to share knowledge and learn, some perceptions shared by our interviewees referred to the behaviour of junior and senior employees, nonetheless, the major finding concerned negative age-related stereotypes. What both generations agreed on is that their job is becoming increasingly challenging

Awareness of and experience with online outsourcing journalism labor markets: A benchmark study of freelance journalists

Online outsourcing markets (OOMs), those sites that connect buyers and sellers of digital labor, have grown dramatically, attracting a global cadre of freelance workers. Journalism OOMs are beginning to have an impact on the buying and selling of freelance journalism. This paper is an exploration of early effects, reporting findings of a survey (n=453) of freelance journalists who use OOMs and those who don’t, or don’t yet. The paper reviews recent scholarship on OOMs and freelance journalists. Freelance journalists were asked about their awareness of and experience with journalism OOMs. Considering OOMs only recently started diffusing, analysis shows a relatively high level of awareness and use of OOMs, plus perceptions about their value for obtaining work, working conditions and monetary and intrinsic rewards

Extracting Recombination Parameters from Impedance Measurements on Organic Solar Cells

Nongeminate recombination in organic solar cells is one of the main causes of reduced device performances. The quantification, and the subsequent reduction, of nongeminate recombination losses requires the development of methods, which allow an accurate and reliable determination of the charge-carrier density, mobility, and lifetime. Here, we present a method, based on the charge-density dependence of the recombination current, to determine the recombination parameters from impedance measurements of organic solar cells. We show that the use of the difference between the capacitance under illumination and the capacitance in the dark for the calculation of the charge density present in the active layer, allows the identification of the dominant recombination mechanism and the subsequent determination of either the charge-carrier lifetime or the bimolecular recombination coefficient
