    Determinants of Formal Giving in Turkey
    (2017) Çarkoğlu, Ali; Aytaç, Selim Erdem; Campbell, David A.
    This article shares the results of a recent study on individual giving to civil society organizations in Turkey. Using interview data collected from a random sample of 2,495 Turkish citizens in 2015, we estimate that about 12% to 13% of the Turkish population engage in giving, a relatively low figure compared to international giving. We find that being male, being educated, being satisfied with one’s income, being satisfied with one’s economic circumstances, being a rural resident, as well as one’s level of religiosity, civic activism, and institutional trust are all positively associated with giving in Turkey. Our findings provide a foundation for understanding philanthropic giving in Turkey and contribute to ongoing research about determinants of individual giving across countries.

    Evaluation and Performance Measurement
    (Routledge, 2020) Benjamin, Lehn M.; Campbell, David A.
    This chapter addresses the state of knowledge of evaluation practice in nonprofit organizations. It summarizes management research on this topic, identifying unanswered questions and suggesting future lines of inquiry to advance understanding. The chapter starts with a review, a brief history of evaluation’s emergence as a distinct field of knowledge before turning to its adoption by nonprofit organizations. Research on evaluation practice in nonprofit organizations shows a consistent set of challenges that affect nonprofits’ ability to do evaluation well, including lack of expertise, limited time and funding to support evaluation, and funding reporting requirements that are not aligned with organizations’ evaluation needs. Research also reveals a constant tension facing nonprofit organizations between using evaluation to learn and inform decision making versus using evaluation to prove to funders and other stakeholders that the organization is worth supporting. Despite the progress that has been made to advance our understanding of evaluation practice in nonprofit organizations, deepening our knowledge in this area will require more comparative and longitudinal research as well as qualitative research that examines how the same evaluation practices and tools are interpreted and understood in different contexts.

    Unveiling Prescribing Patterns: A Systematic Review of Chronic Opioid Prescriptions After Head and Neck Cancer Surgeries
    (Wiley, 2025) Karki, Sabin; Stephanian, Brooke; Ramirez, Mirian; Moore, Michael G.; Campbell, David A.; Chen, Diane W.; Sim, Michael W.; Yesensky, Jessica A.; Mantravadi, Avinash; Farlow, Janice L.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Objective: This study aims to review opioid prescribing changes for pain management in head and neck cancer (HNC) surgery patients, given the recent focus on Enhanced Recovery After Surgery protocols. Data sources: MEDLINE, Embase, and CENTRAL, covering 1998 to 2023. Review methods: We selected studies that evaluated opioid prescribing patterns post-major HNC surgery in various settings, including tertiary care hospitals and community hospitals. Primary outcomes considered were prevalence and patterns of opioid use post-surgery, as well as related outcomes such as chronic use and side effects. Results: Of 1278 abstracts, 24 studies involving 17,027 patients from the United States, China, and Canada met inclusion criteria. Quality was assessed using the MINORS scale, with an average score of 9.9 for non-comparative studies and 20.0 for comparative studies. Persistent opioid use post-surgery, defined as ongoing prescriptions 90 days after treatment, was noted in 15.4% to 64% of patients. Two studies reported adverse events, with up to 16% of patients experiencing side effects. Risk factors for chronic use included preoperative opioid use, tobacco use, higher cancer stage, adjuvant treatment, and demographic factors. Correlations were found between larger opioid prescriptions and shorter survival in advanced cancers. There was notable variability in patient-reported pain control. Conclusion: Persistent opioid use post-HNC surgery is common, with variable efficacy and risk of adverse effects. Tailoring pain management to individual risk factors and focusing on multimodal analgesia could reduce the risks of continued opioid use. Future prospective studies are required to identify optimal pain management strategies.
