Do people invest in local public goods with long-term benefits: Experimental evidence from a shanty town in Peru

This paper discusses voluntary contributions to health education in a shanty town in Peru, using a new experimental setup to identify voluntary contributions to local public goods. The experiment enables individuals to contribute to a health education meeting facilitated by an NGO, which they know will only be organised if the cumulative investment level exceeds a certain threshold value. In contrast to expectations of aid distributors, individuals contributed a substantial amount of money, despite the long-term nature of the health benefits from health education. High discount rates only seem to have had a detrimental effect on investment in a poorer subsample. Results from a complementary experiment, which identifies donations to a nutrition program, suggest that positive beliefs about short-term benefits from health education in the form of learning effects have played an important role in the investment decision. The results indicate that channelling decision-making power about public good provision to beneficiaries not necessarily implies a crowding out of investment in local public goods with long-term benefits. Hence, particular attention is given to the potential role of cash transfers in the financing of local public goods.Health education, Field Experiment, Public Good, Peru

Women's Autonomy and Subjective Well-Being in India: How Village Norms Shape the Impact of Self-Help Groups

This paper presents quasi-experimental impact estimates of women self-help groups on subjective well-being in Orissa, India. We find that, on average, self-help group membership does not affect subjective well-being. However, our results at the same time reveal that subjective well-being sharply declines for those members whose newly gained autonomy meets with relatively conservative social gender norms among non-members. We interpret this finding as evidence for heterogeneous losses of feelings of identity for self-help group members. Identity losses loom larger when women’s enhanced autonomy implies a stronger violation of social gender norms at the community level. Social sanctioning mechanisms play an important role in the heterogeneous negative impact on subjective well-being, as evidenced by qualitative accounts of women’s empowerment trajectories in the research area.Autonomy; Subjective Well-Being; Impact Evaluation; Identity; Sanctioning; India

Feshbach Spectroscopy of a Shape Resonance

We present a new spectroscopy technique for studying cold-collision properties. The technique is based on the association and dissociation of ultracold molecules using a magnetically tunable Feshbach resonance. The energy and lifetime of a shape resonance are determined from a measurement of the dissociation rate. Additional spectroscopic information is obtained from the observation of a spatial interference pattern between an outgoing s wave and d wave. The experimental data agree well with the results from a new model, in which the dissociation process is connected to a scattering gedanken experiment, which is analyzed using a coupled-channels calculation.Comment: Introduction rewritte

Dissociation of Feshbach Molecules into Different Partial Waves

Ultracold molecules can be associated from ultracold atoms by ramping the magnetic field through a Feshbach resonance. A reverse ramp dissociates the molecules. Under suitable conditions, more than one outgoing partial wave can be populated. A theoretical model for this process is discussed here in detail. The model reveals the connection between the dissociation and the theory of multichannel scattering resonances. In particular, the decay rate, the branching ratio, and the relative phase between the partial waves can be predicted from theory or extracted from experiment. The results are applicable to our recent experiment in 87Rb, which has a d-wave shape resonance.Comment: Added Refs.[32-38

An Analysis of the Environments of FU Orionis Objects with Herschel

We present Herschel-HIFI, SPIRE, and PACS 50-670 {\mu}m imaging and spectroscopy of six FU Orionis-type objects and candidates (FU Orionis, V1735 Cyg, V1515 Cyg, V1057 Cyg, V1331 Cyg, and HBC 722), ranging in outburst date from 1936-2010, from the "FOOSH" (FU Orionis Objects Surveyed with Herschel) program, as well as ancillary results from Spitzer-IRS and the Caltech Submillimeter Observatory. In their system properties (Lbol, Tbol, line emission), we find that FUors are in a variety of evolutionary states. Additionally, some FUors have features of both Class I and II sources: warm continuum consistent with Class II sources, but rotational line emission typical of Class I, far higher than Class II sources of similar mass/luminosity. Combining several classification techniques, we find an evolutionary sequence consistent with previous mid-IR indicators. We detect [O I] in every source at luminosities consistent with Class 0/I protostars, much greater than in Class II disks. We detect transitions of 13CO (J_up of 5 to 8) around two sources (V1735 Cyg and HBC 722) but attribute them to nearby protostars. Of the remaining sources, three (FU Ori, V1515 Cyg, and V1331 Cyg) exhibit only low-lying CO, but one (V1057 Cyg) shows CO up to J = 23 - 22 and evidence for H2O and OH emission, at strengths typical of protostars rather than T Tauri stars. Rotational temperatures for "cool" CO components range from 20-81 K, for ~ 10^50 total CO molecules. We detect [C I] and [N II] primarily as diffuse emission.Comment: 31 pages, 15 figures; accepted to Ap

Pharmacists and pharmacy students' perceptions on how a new teaching model supports their clinical decision-making

Background and purpose: Clinical decision-making (CDM) is crucial in pharmacy practice, necessitating effective teaching in undergraduate and postgraduate pharmacy education. This study aims to explore undergraduates and postgraduates' perceptions of how a new teaching model supports their CDM when addressing patient cases. Educational activity and setting: Implemented in a full-day CDM course for pharmacy students and a half-day course for pharmacists in the Netherlands, the model, accompanied by a learning guide, facilitated CDM in patient cases. Eight courses were conducted between September 2022 to June 2023, followed by an online survey measuring participants' agreement on how the model supported their CDM, using a 5-point Likert scale. Additionally, three open-ended questions were included to elicit learning outcomes and self-development opportunities. Findings: Of 175 invited participants, 159 (91%) completed the survey. Most agreed the teaching model supported their CDM, particularly in considering the patient's healthcare needs and context (96%), and exploring all available options (96%). Participants found the model provided a clear structure (97%), and fostered critical thinking (93%). The most frequently mentioned learning outcomes and self-development opportunities included collecting sufficient relevant information, maintaining a broad perspective, and decelerating the process to avoid premature closure. Participants agreed that the teaching model helped them to make clinical decisions. Both undergraduate and postgraduate pharmacy education could possibly benefit from the teaching model's implementation in supporting pharmacy students and pharmacists conducting CDM in pharmacy practice
