Paid and unpaid labor in nonprofit organizations: Does the substitution effect exist?Bittschi, Benjamin, Pennerstorfer, Astrid, Schneider, Ulrike 12 1900 (has links) (PDF)
In nonprofit organizations (NPOs) volunteers often work alongside paid workers. Such
a coproduction setting can lead to tension between the two worker groups. This paper
examines for the first time if and how volunteers in
uence the separation of paid employees,
and thus it contributes to the debate over whether volunteers can substitute paid workers.
Using Austrian data on an organizational level we find a significant impact of volunteers
on the separations of paid workers in NPOs facing increased competition. These findings
support the assumption that a partial substitution effect exists between paid workers and
volunteers.

Greening with Care: Exploring Environmental Justice in Philadelphia's Urban Green Infrastructure Through a Feminist Labor LensRiedman, Elizabeth C, 0000-0001-6781-7523 05 1900 (has links)
Cities around the United States are looking to urban green infrastructure (UGI) as a critical investment to help address a host of urban challenges, including stormwater management, climate change mitigation, rising heat temperatures and increased risk of flooding. As a result, volunteers are being asked to help construct, maintain, and contribute to UGI projects. Current investigations of UGI highlight the need to consider UGI from an environmental justice perspective, emphasizing a three-pronged approach including distribution, recognition, and procedural justice. This dissertation seeks to investigate UGI equity from a labor perspective, specifically how volunteer labor is acknowledged, valued, and contributed among race, class, and gender. Using UGI initiatives in Philadelphia, PA as a case study, it asks; to what extent are urban sustainability initiatives in Philadelphia relying upon the unpaid labor of citizens in the construction of new, UGI? How might this labor exhibit unrecognized forms of social reproductive labor, when observed from an intersectional feminist perspective? How has the contribution of UGI (such as trees, parks) labor changed over time? Drawing from a range of qualitative methods, including ethnographic fieldwork, online surveys, semi-structured interviews, oral histories and archival analysis, results reveal how volunteers play a significant role in the construction and maintenance of UGI over the past hundred years, including the often-invisible contributions of women and women of color. In applying a feminist labor lens, findings suggest gender and racial inequities in how UGI labor is acknowledged and paid as infrastructure work. Future research must consider intersectional labor dimensions as a key component in achieving a more ‘just’ urban green environment for all. / Geography / Geography

Quantitative Decision Models for Humanitarian LogisticsFalasca, Mauro 21 September 2009 (has links)
Humanitarian relief and aid organizations all over the world implement efforts aimed at recovering from disasters, reducing poverty and promoting human rights. The purpose of this dissertation is to develop a series of quantitative decision models to help address some of the challenges faced by humanitarian logistics.
The first study discusses the development of a spreadsheet-based multicriteria scheduling model for a small development aid organization in a South American developing country. Development aid organizations plan and execute efforts that are primarily directed towards promoting human welfare. Because these organizations rely heavily on the use of volunteers to carry out their social mission, it is important that they manage their volunteer workforce efficiently. In this study, we demonstrate not only how the proposed model helps to reduce the number of unfilled shifts and to decrease total scheduling costs, but also how it helps to better satisfy the volunteers’ scheduling preferences, thus supporting long-term retention and effectiveness of the workforce.
The purpose of the second study is to develop a decision model to assist in the management of humanitarian relief volunteers. One of the challenges faced by humanitarian organizations is that there exist limited decision technologies that fit their needs while it has also been pointed out that those organizations experience coordination difficulties with volunteers willing to help. Even though employee workforce management models have been the topic of extensive research over the past decades, no work has focused on the problem of managing humanitarian relief volunteers. In this study, we discuss a series of principles from the field of volunteer management and develop a multicriteria optimization model to assist in the assignment of both individual volunteers and volunteer groups to tasks. We present illustrative examples and analyze two complementary solution methodologies that incorporate the decision maker's preferences and knowledge and allow him/her to trade-off conflicting objectives.
The third study discusses the development of a decision model for the procurement of goods in humanitarian efforts. Despite the prevalence of procurement expenditures in humanitarian efforts, procurement in humanitarian contexts is a topic that has only been discussed in a qualitative manner in the literature. In our paper, we introduce a two stage decision model with recourse to improve the procurement of goods in humanitarian relief supply chains and present an illustrative example. Conclusions, limitations, and directions for future research are also discussed. / Ph. D.
