I give at the office: A review of workplace giving research, theory, and practice

Workplace giving is a widely used philanthropic tool. Although it may have great unmet potential, it is also facing a number of challenges, including competition from informal crowdfunding campaigns. In the face of such challenges, we take stock of the extant research to better understand the value and future of workplace giving, emphasizing employee actions and preferences in our review. Workplace giving studies can also augment knowledge about contextual giving or bounded settings for exploring basic philanthropic questions (e.g., donor control or gift elasticity). We use a three‐part conceptual framework to synthesize and discuss research on individual workplace giving in the context of broader giving behaviors. We address what researchers know, do not know, and need to know on the topic of workplace giving

The Global Common Good and the Future of Academic Professionals

In this epilogue to the special issue of Higher Learning Research Communications dedicated to higher education, community engagement, and the public good, Shaker addresses the unifying concept presented across the issue: the common good. For Shaker, this special issue responds to UNESCO’s call for educational institutions and educators to rethink education in the contemporary era and focuses on how academic endeavors can, do, and should act in service to a global common good. The essay stresses the academic workforce needs to be reimagined concurrently with rethinking the systems of education that will ensure the world and society “to which we aspire.” Faculty in all their diversity are the central and essential ingredient to a successful global educational response to the challenges of an equitable and just global society will create and disseminate the knowledge society needs. To close, Shaker notes publications such as this bring these conversations into sharper focus to align and connect them so that a rethought approach to higher education might generate discernible results within the relatively short time available

Dynamic analysis of space-related linear and non-linear structures

In order to be cost effective, space structures must be extremely light weight, and subsequently, very flexible structures. The power system for Space Station Freedom is such a structure. Each array consists of a deployable truss mast and a split blanket of photovoltaic solar collectors. The solar arrays are deployed in orbit, and the blanket is stretched into position as the mast is extended. Geometric stiffness due to the preload make this an interesting non-linear problem. The space station will be subjected to various dynamic loads, during shuttle docking, solar tracking, attitude adjustment, etc. Accurate prediction of the natural frequencies and mode shapes of the space station components, including the solar arrays, is critical for determining the structural adequacy of the components, and for designing a dynamic controls system. The process used in developing and verifying the finite element dynamic model of the photo-voltaic arrays is documented. Various problems were identified, such as grounding effects due to geometric stiffness, large displacement effects, and pseudo-stiffness (grounding) due to lack of required rigid body modes. Analysis techniques, such as development of rigorous solutions using continuum mechanics, finite element solution sequence altering, equivalent systems using a curvature basis, Craig-Bampton superelement approach, and modal ordering schemes were utilized. The grounding problems associated with the geometric stiffness are emphasized

New record of Cypridopsis vidua (Muller, 1776) (Ostracoda, Podocopida: Cyprididae) from East Al-Hammar Marshes, Iraq

In the present study, Cypridopsis vidua (Muller, 1776), was recorded for the first time from the East Al-Hammar marshes, South of Ira. This species was collected from three stations during January and December 2021. The morphological features of the collected specimens were described for further taxonomic studies. In addition, some water quality parameters viz. temperature, PH, salinity, dissolved oxygen, turbidity, conductivity, and total dissolved solids were measured of the sampling station during the study period are provided.&nbsp

Mass study for modular approaches to a solar electric propulsion module

The propulsion module comprises six to eight 30-cm thruster and power processing units, a mercury propellant storage and distribution system, a solar array ranging in power from 18 to 25 kW, and the thermal and structure systems required to support the thrust and power subsystems. Launch and on-orbit configurations are presented for both modular approaches. The propulsion module satisfies the thermal design requirements of a multimission set including: Mercury, Saturn, and Jupiter orbiters, a 1-AU solar observatory, and comet and asteroid rendezvous. A detailed mass breakdown and a mass equation relating the total mass to the number of thrusters and solar array power requirement is given for both approaches

Understanding Higher Education Fundraisers in the United States

Since their earliest days, the U.S. higher education institutions have relied on philanthropic support to achieve their missions. What began as incidental is now a highly organized process of fundraising that accounts for tens of billions of dollars annually. As institutions' desire for private support grows, so too does the demand for successful fundraising professionals. Drawing on qualitative and quantitative analysis, this survey‐based study (n = 508) of U.S. higher education fundraising personnel provides new knowledge and grounds fundraisers' position in historical and contemporary literature about fundraisers and professionalism. The findings highlight notable generational, income, and gender differences within the higher education sector and between higher education and the greater profession. The analysis shows an established knowledge‐base and set of learnable skills for higher education fundraisers—which are best applied when combined with particular personal attributes. Although the latter are critically important, without full and fair attention to the former, the occupation is unlikely to garner full professional status. This study highlights, the path forward highlights the complexity of contemporary fundraising, is a reminder that fundraising is relationship‐ and information‐driven, and indicates that select, strategic efforts can further professionalize the field. In particular, fundraisers in the education sector may have special opportunities to advance the professionalization of their occupation

The Global Public Good: Students, Higher Education, and Communities of Good

Along with introducing the purpose and cohesion of the essays that form this special issue, we also wish to highlight the force on which all of these lofty hopes depend: educated students. Without question, the authors who wrote these essays understand and appreciate the importance of students, especially as the prepared and empowered agents of future actions that will be sustainably transformative in the conduct of their lives. In fact, students are so pervasively important to most discussions of higher education and the public good, including the UNESCO report, that they are often taken for granted in a rush to address institutional and faculty responsibilities. However, no student of any age or educational goal should ever be far from consideration. They are indeed fully present in the essays that comprise this issue of Higher Learning Research Communications

A mechanical, thermal and electrical packaging design for a prototype power management and control system for the 30 cm mercury ion thruster

A prototype electric power management and thruster control system for a 30 cm ion thruster is described. The system meets all of the requirements necessary to operate a thruster in a fully automatic mode. Power input to the system can vary over a full two to one dynamic range (200 to 400 V) for the solar array or other power source. The power management and control system is designed to protect the thruster, the flight system and itself from arcs and is fully compatible with standard spacecraft electronics. The system is easily integrated into flight systems which can operate over a thermal environment ranging from 0.3 to 5 AU. The complete power management and control system measures 45.7 cm (18 in.) x 15.2 cm (6 in.) x 114.8 cm (45.2 in.) and weighs 36.2 kg (79.7 lb). At full power the overall efficiency of the system is estimated to be 87.4 percent. Three systems are currently being built and a full schedule of environmental and electrical testing is planned

Modular thrust subsystem approaches to solar electric propulsion module design

Three approaches are presented for packaging the elements of a 30 cm ion thruster subsystem into a modular thrust subsystem. The individual modules, when integrated into a conceptual solar electric propulsion module are applicable to a multimission set of interplanetary flights with the space shuttle interim upper stage as the launch vehicle. The emphasis is on the structural and thermal integration of the components into the modular thrust subsystems. Thermal control for the power processing units is either by direct radiation through louvers in combination with heat pipes or an all heat pipe system. The propellant storage and feed system and thruster gimbal system concepts are presented. The three approaches are compared on the basis of mass, cost, testing, interfaces, simplicity, reliability, and maintainability

What Works at Work? Toward an Integrative Model Examining Workplace Campaign Strategies

Many US employees are regularly asked to give charitable donations through work. The techniques used to solicit workplace donations vary. Drawing on a nationally representative survey, the study used a sample of donor responses to examine the effectiveness of several widely used campaign strategies: donor choice, company matching, public recognition, and solicitation support. The theoretical framework built on workplace research by Barman (2007) and established charitable giving mechanisms (Bekkers and Wiepking 2011a, 2011b). The research question was, “Do workplace campaign strategies lead employees to participate and to make (larger) donations in the workplace?” The positive outcomes of the strategies, aside from donor choice, were limited, suggesting that tried‐and‐true workplace fundraising strategies warrant additional scrutiny. The findings are meaningful to campaign managers seeking to identify approaches that generate workplace giving. For researchers, the results confirm growing attention to the importance of purpose‐based giving in comparison with community‐based giving
