Determinants of Compensation for Fundraising Professionals: A Study of Pay, Performance, and Gender Differences
The purpose of our study is to address the following research questions: (1) what are the significant determinants of compensation for individuals who are employed as fundraising professionals in nonprofits? More specifically, does performance have a significant effect on compensation? (2) What are the key determinants of bonus and salary for these individuals? (3) Is there a genderâpay gap for individuals who are in the role of fundraisers for nonprofits? Each is discussed bel
Phenyl-triazine oligomers for light-driven hydrogen evolution
The design of stable, yet highly tunable organic photocatalysts which orchestrate multi-step electron transfer reactions is at the heart of the newly emerging field of polymer photocatalysis. Covalent triazine frameworks such as the archetypal CTF-1 have been theorized to constitute a new class of photocatalytically active polymers for light-driven water splitting. Here, we revisit the ionothermal synthesis of CTF-1 by trimerization of 1,4-dicyanobenzene catalyzed by the Lewis acid zinc chloride and demonstrate that the microporous black polymer CTF-1 is essentially inactive for hydrogen evolution. Instead, highly photoactive phenyl-triazine oligomers (PTOs) with higher crystallinity as compared to CTF-1 are obtained by lowering the reaction temperature to 300 °C and prolonging the reaction time to >150 hours. The low reaction temperature of the PTOs largely prevents incipient carbonization and thus results in a carbon-to-nitrogen weight ratio close to the theoretical value of 3.43. The oligomers were characterized by MALDI-TOF and quantitative solid-state NMR spectroscopy, revealing variations in size, connectivity and thus nitrile-to-triazine ratios depending on the initial precursor dilution. The most active PTO samples efficiently and stably reduce water to hydrogen with an average rate of 1076 (±278) ÎŒmol hâ1 gâ1 under simulated sunlight illumination, which is competitive with the best carbon nitride-based and purely organic photocatalysts. The photocatalytic activity of the PTOs is found to sensitively depend on the polymerization degree, thus suggesting a prominent role of the unreacted nitrile moieties in the photocatalytic process. Notably, PTOs even show moderate hydrogen production without the addition of any co-catalyst
Photobase Generator Enabled Pitch Division: A Progress Report
Pitch division lithography (PDL) with a photobase generator (PBG) allows printing of grating images with twice the pitch of a mask. The proof-of-concept has been published in the previous paper[1, 2] and demonstrated by others[1]. Forty five nm half-pitch (HP) patterns were produced using a 90nm HP mask, but the image had line edge roughness (LER) that does not meet requirements. Efforts have been made to understand and improve the LER in this process. Challenges were summarized toward low LER and good performing pitch division. Simulations and analysis showed the necessity for an optical image that is uniform in the z direction in order for pitch division to be successful. Two-stage PBGs were designed for enhancement of resist chemical contrast. New pitch division resists with polymer-bound PAGs and PBGs, and various PBGs were tested. This paper focuses on analysis of the LER problems and efforts to improve patterning performance in pitch division lithography.Chemical Engineerin
All in for Women & Girls: How womenâs fund and foundation donors are leading through philanthropy
To date, studies of womenâs funds and foundations have been qualitative in nature,
and have studied the organizations more than their donors. This study examines,
in a comprehensive and quantitative manner, the impact of womenâs fund and
foundation donors on womenâs and girlsâ causes. Previous research has shed light on
womenâs funds and foundations, on giving to women and girls, and on the impact of
high-net-worth donors. This report addresses the intersection of these three factors
to ask: What unique role do high-net-worth donors to womenâs funds and foundations
play in catalyzing support for womenâs and girlsâ causes
Utility of Parental Mediation Model on Youthâs Problematic Online Gaming
The Parental Mediation Model PMM) was initially designed to regulate childrenâs attitudes towards the traditional media. In the present era, because of prevalent online media there is a need for similar regulative measures. Spending long hours on social media and playing online games increase the risks of exposure to the negative outcomes of online gaming. This paper initially applied the PMM developed by European Kids Online to (i) test the reliability and validity of this model and (ii) identify the effectiveness of this model in controlling problematic online gaming (POG). The data were collected from 592 participants comprising 296 parents and 296 students of four foreign universities, aged 16 to 22 years in Kuala Lumpur (Malaysia). The study found that the modified model of the five-factor PMM (Technical mediation, Monitoring mediation, Restrictive mediation, Active Mediation of Internet Safety, and Active mediation of Internet Use) functions as a predictor for mitigating POG. The findings suggest the existence of a positive relation between âmonitoringâ and ârestrictiveâ mediation strategies and exposure to POG while Active Mediation of Internet Safety and Active mediation of Internet use were insignificant predictors. Results showed a higher utility of âtechnicalâ strategies by the parents led to less POG. The findings of this study do not support the literature suggesting active mediation is more effective for reducing youthâs risky behaviour. Instead, parents need to apply more technical mediations with their children and adolescentsâ Internet use to minimize the negative effects of online gaming
Development of Trust in an Online Breast Cancer Forum: A Qualitative Study
Background: Online health forums provide peer support for a range of medical conditions, including
life-threatening and terminal illnesses. Trust is an important component of peer-to-peer support,
although relatively little is known about how trust forms within online health forums.
Objective: The aim of this paper is to examine how trust develops and influences sharing among
users of an online breast cancer forum.
Methods: An interpretive qualitative approach was adopted. Data were collected from forum posts
from 135 threads on nine boards on the UK charity, Breast Cancer Care (BCC). Semi-structured
interviews were conducted with 14 BCC forum users. Both datasets were analysed thematically using
Braun and Clarkeâs [2006] approach and combined to triangulate analysis.
Results: Trust operates in three dimensions, structural, relational and temporal, which intersect with
each other and do not operate in isolation. The structural dimension relates to how the affordances
and formal rules of the site affected trust. The relational dimension refers to how trust was
necessarily experienced in interactions with other forum users: it emerged within relationships and
was a social phenomenon. The temporal dimension relates to how trust changed over time and was
influenced by the length of time users spent on the forum.
Conclusions: Trust is a process that changes over time, and which is influenced by structural features
of the forum and informal but collectively understood relational interactions among forum users.
The study provides a better understanding of how the intersecting structural, relational and
temporal aspects that support the development of trust facilitate sharing in online environments.
These findings will help organisations developing online health forums
The Use of Sexually Explicit Internet Material and Its Antecedents: A Longitudinal Comparison of Adolescents and Adults
An implicit assumption in research on adolescentsâ use of sexually explicit internet material (SEIM) is that they may feel more attracted to such material than adults, given the âforbiddenâ character of SEIM for minors. However, systematic comparisons between adolescentsâ and adultsâ SEIM use and of its antecedents are missing. We conducted a two-wave panel survey among a nationally representative sample of 1,445 Dutch adolescents and a nationally representative sample of 833 Dutch adults. Adolescentsâ and adultsâ SEIM use was similar. When significant differences in the SEIM use occurred, they indicated that adults used SEIM more often than adolescents. Male adults were the most frequent users of SEIM. No difference in the antecedent structure of SEIM use emerged between adolescents and adults. In both groups, males, sensation seekers, as well as people with a not exclusively heterosexual orientation used SEIM more often. Among adolescents and adults, lower life satisfaction increased SEIM use. Our findings suggest that the frequency of SEIM use and its antecedents are largely the same among adolescents and adults

Professors on the Board: Do They Contribute to Society Outside the Classroom?
According to our data, 38.5 % of S&P 1500 firms have at least one professor on their boards. Given the lack of research examining the roles and effects of academic faculty as members of boards of directors (professorâdirectors) on corporate outcomes, this study investigates whether firms with professorâdirectors are more likely to exhibit higher corporate social responsibility (CSR) performance ratings. Results indicate that firms with professorâdirectors do exhibit higher CSR performance ratings than those without. However, the influence of professorâdirectors on firm CSR performance ratings depends on their academic backgroundâthe positive association between the presence of professorâdirectors and firm CSR performance ratings is significant only when their academic background is specialized (e.g., science, engineering, and medicine). Finally, this positive association weakens when professorâdirectors hold an administrative position at their universities
