The price elasticity of charitable giving : does the form of tax relief matter?

This paper uses a survey-based approach to test alternative methods of channeling tax relief to donors – as a tax rebate for the donor or as a matched payment to the receiving charity. On accounting grounds these two are equivalent but, in line with earlier experimental studies, we find that gross donations are significantly more responsive to a match change than to a rebate change. We show that the difference can largely be explained by the fact that a majority of donors do not adjust their nominal donations in response to a change in subsidy. This evidence adds to the growing empirical literature suggesting that consumers may not react to tax changes. In the case of tax subsidies for donations, this has implications for policy design – for the UK a match-based system is likely to be more effective at increasing money going to charities

Double-Peaked Narrow-Line Active Galactic Nuclei. II. The Case Of Equal Peaks

Active galactic nuclei (AGNs) with double-peaked narrow lines (DPAGNs) may be caused by kiloparsec-scale binary AGNs, bipolar outflows, or rotating gaseous disks. We examine the class of DPAGNs in which the two narrow-line components have closely similar intensity as being especially likely to involve disks or jets. Two spectroscopic indicators support this likelihood. For DPAGNs from Smith et al., the "equal-peaked" objects (EPAGNs) have [Ne V]/[O III] ratios lower than for a control sample of non-double-peaked AGNs. This is unexpected for a pair of normal AGNs in a galactic merger, but may be consistent with [O III] emission from a rotating ring with relatively little gas at small radii. Also, [O III]/H beta ratios of the redshifted and blueshifted systems in the EPAGN are more similar to each other than in a control sample, suggestive of a single ionizing source and inconsistent with the binary interpretation.University Cooperative Society of the University of Texas at AustinJane and Roland Blumberg Cenntenial Professorship in AstronomyAlfred P.

Clients\u27 Experiences Giving Gifts to Therapists

Nine therapy clients were interviewed regarding their experiences of giving gifts to therapists. Data were analyzed using consensual qualitative research. In describing a specific event when they gave a gift that was accepted, participants described having a good relationship with the therapist and usually identified their therapy concerns as relationship or family struggles or both. Most bought a relatively inexpensive gift they thought their therapist would like and gave it during a nontermination session to express appreciation or mark an important life event. Most participants acknowledged mixed emotions when giving the gift and noted that any discussion of the gift was brief and did not explore its deeper meaning. Nevertheless, most participants perceived that gift events positively affected them and their therapists

How important is pro-social behaviour in the delivery of public services?

A number of papers have posited that there is a relationship between institutional structure and pro-social behaviour, in particular donated labour, in the delivery of public services, such as health, social care and education. However, there has been very little empirical research that attempts to measure whether such a relationship exists in practice. This is the aim of this paper. Including a robust set of individual and job-specific controls, we find that individuals in the non-profit sector are significantly more likely to donate their labour, measured by unpaid overtime, than those in the for-profit sector. We can reject that this difference is simply due to implicit contracts or social norms. We find some evidence that individuals differentially select into the non-profit and for-profit sectors according to whether they donate their labour.pro-social behaviour; public services; donated labour; motivation

The Jet-Driven Outflow In The Radio Galaxy SDSS J1517+3353: Implications For Double-Peaked Narrow-Line Active Galactic Nucleus

We report on the study of an intriguing active galaxy that was selected as a potential multiple supermassive black hole merger in the early-type host SDSS J151709.20+335324.7 (z = 0.135) from a complete search for double-peaked [O III] lines from the SDSS spectroscopic quasi-stellar object (QSO) database. Ground-based SDSS imaging reveals two blue structures on either side of the photometric center of the host galaxy, separated from each other by about 5.7 kpc. From a combination of SDSS fiber and Keck/HIRES long-slit spectroscopy, it is demonstrated that, in addition to these two features, a third distinct structure surrounds the nucleus of the host galaxy. All three structures exhibit highly ionized line emission with line ratios characteristic of Seyfert II active galactic nuclei. The analysis of spatially resolved emission-line profiles from the HIRES spectrum reveal three distinct kinematic subcomponents, one at rest and the other two moving at -350 km s(-1) and 500 km s(-1) with respect to the systemic velocity of the host galaxy. A comparison of imaging and spectral data confirm a strong association between the kinematic components and the spatial knots, which implies a highly disturbed and complex active region in this object. A comparative analysis of the broadband positions, colors, kinematics, and spectral properties of the knots in this system lead to two plausible explanations: (1) a multiple active galactic nucleus (AGN) produced due to a massive dry merger, or (2) a very powerful radio jet-driven outflow. Subsequent VLA radio imaging reveals a clear jet aligned with the emission-line gas, confirming the latter explanation. We use the broadband radio measurements to examine the impact of the jet on the interstellar medium of the host galaxy, and find that the energy in the radio lobes can heat a significant fraction of the gas to the virial temperature. Finally, we discuss tests that may help future surveys distinguish between jet-driven kinematics and true black-hole binaries. J1517+3353 is a remarkable laboratory for AGN feedback and warrants deeper follow-up study. In the Appendix, we present high-resolution radio imaging of a second AGN with double-peaked [O III] lines, SDSS J112939.78+605742.6, which shows a sub-arcsecond radio jet. If the double-peaked nature of the narrow lines in radio-loud AGNs are generally due to radio jet interactions, we suggest that extended radio structure should be expected in most of such systems.NSF AST-0507483, AST-0808133University of Texas at AustinAlfred P.

Relational altruism and giving in social groups

Much fundraising is done by individuals within existing social groups. Exploiting a unique dataset, we demonstrate (i) a positive relationship between social group size and the number of donations; (ii) a negative relationship between group size and the size of individual donations; (iii) no clear relationship between group size and the total amount raised. Free riding with respect to the activity being funded cannot explain the relationship between group size and donation size, since the number of social group members is only a subset of total contributors. Instead, the findings are consistent with the notion that giving in social groups is motivated by “relational altruism”

ESTABLISHING THE RELIABILITY OF TOTAL BODY CENTER OF GRAVITY VALUES

At the CIC Big Ten Symposium on Biomechanics in October, 1980, two of the presentations focused on measurement and statistical considerations in biomechanical research. In both instances, statements were made with respect to the concept of the reliability of biomechanical data. Morris (1980) referenced the observations of Kroll who had noted the poor assessment of reliability and objectivity" (p. 233) in biomechanics research. Disch and Hudson (1980) also noted their concern by stating that "the reliability questions important to the biomechanics researcher are ones of stability and objectivity" but "unfortunately, this important measurement phase of biomechanical research is often overlooked."
