"the other side of the coin": What do business schools teach the typical business undergraduate student about the nonprofit sector? A case study from the Netherlands

This article focuses on the exposure of the typical undergraduate business student to the nonprofit sector and management, as opposed to focusing on learning opportunities available to interested students in particular, as is typically reviewed in research on nonprofit management education. To address this novel question, the authors employed a multimethod research strategy to investigate the coverage of the nonprofit sector in the undergraduate business degree program of a leading international business school: the Rotterdam School of Management, Erasmus University in the Netherlands. Based on an exhaustive review of course syllabi, interviews with faculty members, systematic analysis of course lecture notes, and a student discussion group, the results show rather tepid attention to the nonprofit sector and management in the undergraduate curriculum. The article concludes with a discussion of the implications of these findings for instruction of business administration undergraduate students to prepare them for interaction with the nonprofit sector

Preparation of Au Nanostructure Arrays for Fluorometry and Biosensors Applications

The paper describes the fabrication of random and ordered gold nanostructure arrays (NSA) of different morphology using island film thermal annealing and nanoimprint lithography techniques. Structural parameters of obtained NSA were investigated using atomic force microscopy method. Spectral characteristics of obtained NSA were studied in air atmosphere, and NSA light extinction spectra exhibited an expressed plasmon peak. Spectral position of localized surface plasmon resonance can be tuned depending on geometrical parameters of nanostructures, which is an important factor for resonant investigation methods of various types of molecular structures. Proposed technological approaches can be used to implement the resonance fluorometry in electromagnetic field of nanostructures (surface-enhanced fluorescence) method and in chemical and biosensors based on localized surface plasmon resonance.

Narrow-band photodetection based on M-plane GaN films

Rapid identification of a range of hazardous airborne biological and chemical agents requires simultaneous detection at several specific wavelengths, and consequently a set of photodetectors with very narrow-band spectral responsivity. We demonstrate two ultraviolet photodetection configurations based on strained M-plane GaN films on LiAlO2(100) substrates grown by molecular-beam epitaxy with a detection bandwidth below 8 nm. The optical band gap of the film depends on the orientation of the linear polarization of the incident light relative to the c-axis of GaN, which lies in the film plane. The first configuration consists of a polarizationsensitive planar Schottky photodetector and a filter. An orthogonal alignment of the c-axis of the photodetector and the filter produces a detection system with a peak responsivity at 360 nm and a bandwidth of 6 nm. The second one consists of two planar Schottky photodetectors with their c-axes oriented perpendicular to each other. The difference signal between the two photodetectors produces a peak responsivity at 358 nm and a bandwidth of 7.3 nm

A systematic review of barriers to early presentation and diagnosis with cancer among Black women

Objective: To explore barriers to early presentation and diagnosis with breast cancer among black women. Design: Systematic review. Methods: We searched multiple bibliographic databases (January 1991–February 2013) for primary research, published in English, conducted in developed countries and investigating barriers to early presentation and diagnosis with symptomatic breast cancer among black women (?18 years). Studies were excluded if they did not report separate findings by ethnic group or gender, only reported differences in time to presentation/diagnosis, or reported on interventions and barriers to cancer screening. We followed Cochrane and PRISMA guidance to identify relevant research. Findings were integrated through thematic synthesis. Designs of quantitative studies made meta-analysis impossible. Results: We identified 18 studies (6183 participants). Delay was multifactorial, individual and complex. Factors contributing to delay included: poor symptom and risk factor knowledge; fear of detecting breast abnormality; fear of cancer treatments; fear of partner abandonment; embarrassment disclosing symptoms to healthcare professionals; taboo and stigmatism. Presentation appears quicker following disclosure. Influence of fatalism and religiosity on delay is unclear from evidence in these studies. We compared older studies (?10 years) with newer ones (<10 years) to determine changes over time. In older studies, delaying factors included: inaccessibility of healthcare services; competing priorities and concerns about partner abandonment. Partner abandonment was studied in older studies but not in newer ones. Comparisons of healthy women and cancer populations revealed differences between how people perceive they would behave, and actually behave, on finding breast abnormality. Conclusions: Strategies to improve early presentation and diagnosis with breast cancer among black women need to address symptom recognition and interpretation of risk, as well as fears of the consequences of cancer. The review is limited by the paucity of studies conducted outside the USA and limited detail reported by published studies preventing comparison between ethnic groups

Designing “National Day of Service” Projects to Promote Volunteer Job Satisfaction

National Day of Service (NDS) volunteering events have become common, yet little is known about how the design of such events affects volunteer satisfaction. This relationship is important because volunteer satisfaction ensures a strong volunteer base for special events and promotes sustained volunteerism. We explore how the design of NDS projects promotes volunteer job satisfaction. Our approach to the research question is informed by work design theory. Based on interview, participant observation, and focus-group data from an NDS in the Netherlands, the findings suggest that nonprofit organizations can elicit volunteer job satisfaction by designing NDS projects that create a sense of added value, support productivity, and make volunteers feel comfortable. Designing NDS projects that incorporate task significance, symbolic social support, feedback from others, beneficiary contact, task identity, project preparation, physically demanding work, social support, and limited autonomy help to achieve these goals

NPARSEC : NTT Parallaxes of Southern Extremely Cool objects. Goals, targets, procedures and first results

The discovery and subsequent detailed study of T dwarfs have provided many surprises and pushed the physics and modelling of cool atmospheres in unpredicted directions. Distance is a critical parameter for studies of these objects to determine intrinsic luminosities, test binarity and measure their motion in the Galaxy. We describe a new observational programme to determine distances across the full range of T-dwarf subtypes using the New Technology Telescope (NTT)/SOFI telescope/instrument combination. We present preliminary results for ten objects, five of which represent new distances.Peer reviewe

Reevaluation of the role of nuclear uncertainties in experiments on atomic parity violation with isotopic chains

In light of new data on neutron distributions from experiments with antiprotonic atoms [ Trzcinska {\it et al.}, Phys. Rev. Lett. 87, 082501 (2001)], we reexamine the role of nuclear-structure uncertainties in the interpretation of measurements of parity violation in atoms using chains of isotopes of the same element. With these new nuclear data, we find an improvement in the sensitivity of isotopic chain measurements to ``new physics'' beyond the standard model. We compare possible constraints on ``new physics'' with the most accurate to date single-isotope probe of parity violation in the Cs atom. We conclude that presently isotopic chain experiments employing atoms with nuclear charges Z < 50 may result in more accurate tests of the weak interaction.Comment: 6 pages, 1 fig., submitted to Phys.

Observation of a topologically protected state in a magnetic domain wall stabilized by a ferromagnetic chemical barrier

The precise control and stabilization of magnetic domain walls is key for the development of the next generation magnetic nano-devices. Among the multitude of magnetic configurations of a magnetic domain wall, topologically protected states are of particular interest due to their intrinsic stability. In this work, using XMCD-PEEM, we have observed a topologically protected magnetic domain wall in a ferromagnetic cylindrical nanowire. Its structure is stabilized by periodic sharp alterations of the chemical composition in the nanowire. The large stability of this topologically protected domain wall contrasts with the mobility of other non-protected and non-chiral states also present in the same nanowire. The micromagnetic simulations show the structure and the conditions required to find the topologically protected state. These results are relevant for the design of future spintronic devices such as domain wall based RF oscillators or magnetic memories
