The deterrent effect of voting against minarets: identity utility and foreigners' location choice

This paper uses the vote on the Swiss minaret initiative as a natural experiment to identify the causal effect of negative attitudes towards immigrants on foreigners' location choices and thus indirectly on their utility. Based on a regression discontinuity design with unknown discontinuity points and administrative data on the population of foreigners, we find that the probability of their moving to a municipality that unexpectedly expressed strong reservations decreases initially by about 60 percent. The effect levels off over a period of about 5 months. Consistent with a reduction in the identity utility for immigrants in general, the reaction is not confined to Muslims, whereby high-skilled foreigners seem to be most sensitive to the newly revealed reservations

Behavioral Responses to Local Tax Rates: Quasi-Experimental Evidence from a Foreigners' Tax Scheme in Switzerland

We study behavioral responses to local income taxes exploiting a special tax regime which applies to foreign employees residing in Switzerland. The used institutional setting generates two thresholds through which locally heterogeneous taxation is assigned: An income threshold at 120,000 Swiss francs and a duration threshold at 5 years of stay in Switzerland. We exploit these thresholds by applying a discontinuity in density design and a fuzzy RDD to administrative income data. We find causal evidence for strategic income bunching for wage earners and tax induced intra-national mobility. Several pieces of evidence suggest that individuals have to “learn the tax code” and that knowledge and information transmission through local networks plays a major role in the behavioral response to tax incentives

Precise Control over Legislative Vote Outcomes: A Forensic Approach to Political Economics

We propose a forensic approach to investigate the politico-economic forces that influence narrow vote outcomes in legislative assemblies. Applying nonparametric estimation techniques to a data set covering all roll call votes between 1990 and 2014, we can identify the existence of precise control over legislative vote outcomes in the U.S. House of Representatives. Several pieces of evidence indicate that this control seems to be, at least partly, driven by campaign finance donations. Moreover, control seems to be most prevalent in times of higher electoral competition, i.e. during election years. Our contribution sheds new light on the role of money in politics and, more generally, opens a novel perspective to empirical research on legislative voting

Are asylum seekers more likely to work with more inclusive labor market access regulations?

In the face of recent refugee migration, early integration of asylum seekers into the labor market has been proposed as an important mechanism for easing their economic and social lot in the short as well as in the long term. However, little is known about the policies that foster or hamper their participation in the labor market, in particular during the important initial period of their stay in the host country. In order to evaluate whether inclusive labor market policies increase the labor market participation of asylum seekers, we exploit the variation in asylum policies in Swiss cantons to which asylum seekers are randomly allocated. During our study period from 2011 to 2014, the employment rate among asylum seekers varied between 0% and 30.2% across cantons. Our results indicate that labor market access regulations are responsible for a substantial proportion of these dierences, in which an inclusive regime increases participation by 11 percentage points. The marginal eects are larger for asylum seekers who speak a language that is linguistically close to the one in their host canton

Measuring the In-Process Figure, Final Prescription, and System Alignment of Large Optics and Segmented Mirrors Using Lidar Metrology

The fabrication of large optics is traditionally a slow process, and fabrication capability is often limited by measurement capability. W hile techniques exist to measure mirror figure with nanometer precis ion, measurements of large-mirror prescription are typically limited to submillimeter accuracy. Using a lidar instrument enables one to measure the optical surface rough figure and prescription in virtuall y all phases of fabrication without moving the mirror from its polis hing setup. This technology improves the uncertainty of mirror presc ription measurement to the micron-regime

Absolute Position of Targets Measured Through a Chamber Window Using Lidar Metrology Systems

Lidar is a useful tool for taking metrology measurements without the need for physical contact with the parts under test. Lidar instruments are aimed at a target using azimuth and elevation stages, then focus a beam of coherent, frequency modulated laser energy onto the target, such as the surface of a mechanical structure. Energy from the reflected beam is mixed with an optical reference signal that travels in a fiber path internal to the instrument, and the range to the target is calculated based on the difference in the frequency of the returned and reference signals. In cases when the parts are in extreme environments, additional steps need to be taken to separate the operator and lidar from that environment. A model has been developed that accurately reduces the lidar data to an absolute position and accounts for the three media in the testbed air, fused silica, and vacuum but the approach can be adapted for any environment or material. The accuracy of laser metrology measurements depends upon knowing the parameters of the media through which the measurement beam travels. Under normal conditions, this means knowledge of the temperature, pressure, and humidity of the air in the measurement volume. In the past, chamber windows have been used to separate the measuring device from the extreme environment within the chamber and still permit optical measurement, but, so far, only relative changes have been diagnosed. The ability to make accurate measurements through a window presents a challenge as there are a number of factors to consider. In the case of the lidar, the window will increase the time-of-flight of the laser beam causing a ranging error, and refract the direction of the beam causing angular positioning errors. In addition, differences in pressure, temperature, and humidity on each side of the window will cause slight atmospheric index changes and induce deformation and a refractive index gradient within the window. Also, since the window is a dispersive media, the effect of both phase and group indices have to be considered. Taking all these factors into account, a method was developed to measure targets through multiple regions of different materials and produce results that are absolute measurements of target position in three-dimensional space, rather than simply relative position. The environment in which the lidar measurements are taken must be broken down into separate regions of interest and each region solved for separately. In this case, there were three regions of interest: air, fused silica, and vacuum. The angular position of the target inside the chamber is solved using only phase index and phase velocity, while the ranging effects due to travel from air to glass to vacuum/air are solved with group index and group velocity. When all parameters are solved simultaneously, an absolute knowledge of the position of each target within an environmental chamber can be derived. Novel features of this innovation include measuring absolute position of targets through multiple dispersive and non-dispersive media, deconstruction of lidar raw data from a commercial off-the-shelf unit into reworkable parameters, and use of group velocities to reduce range data. Measurement of structures within a vacuum chamber or other harsh environment, such as a furnace, may now be measured as easily as if they were in an ambient laboratory. This analysis permits transformation of the raw data into absolute spatial units (e.g., mm). This technique has also been extended to laser tracker, theodolite, and cathetometer measurements through refractive media

Australian dust storm associated with extensive Aspergillus sydowii fungal "Bloom" in coastal waters

A massive central Australian dust storm in September 2009 was associated with abundant fungal spores (150,000/m(3)) and hyphae in coastal waters between Brisbane (27 degrees S) and Sydney (34 degrees S). These spores were successfully germinated from formalinpreserved samples, and using molecular sequencing of three different genes (the large subunit rRNA gene [LSU], internal transcribed spacer [ITS], and beta-tubulin gene), they were conclusively identified as Aspergillus sydowii, an organism circumstantially associated with gorgonian coral fan disease in the Caribbean. Surprisingly, no human health or marine ecosystem impacts were associated with this Australian dust storm event. Australian fungal cultures were nontoxic to fish gills and caused a minor reduction in the motility of Alexandrium or Chattonella algal cultures but had their greatest impacts on Symbiodinium dinoflagellate coral symbiont motility, with hyphae being more detrimental than spores. While we have not yet seen any soft coral disease outbreaks on the Australian Great Barrier Reef similar to those observed in the Caribbean and while this particular fungal population was non-or weakly pathogenic, our observations raise the possibility of future marine ecosystem pathogen impacts from similar dust storms harboring more pathogenic strains

Implementing the Systematic Collection of Sexual Orientation and Gender Identity Information in a Community Mental Health Setting

BACKGROUND: Sexual orientation and gender identity (SOGI) information is becoming part of client demographic information collected in many healthcare settings. Inclusion of these data with regularly collected demographic information is becoming mandatory for compliance with federal programs. Collecting SOGI information is not always easy to implement and requires customization to a particular healthcare institution’s processes. METHODS: This quality improvement (QI) project included establishing SOGI questions in a standardized format, client surveys for feedback, an educational intervention with staff, and simple quantitative analysis with t tests. IMPLEMENTATION: This QI project used the Plan Do Study Act (PDSA) method of planning and implementing change. The SOGI questions were introduced at a single outpatient mental health clinic of a statewide private, not-for-profit agency in the southeastern United States. This project consisted of four complete PDSA cycles, with unique changes to the collection process between each. These included informational statements on client forms, ongoing supervised and unsupervised data collection at the clinic, and a staff training regarding both the collection of SOGI data and serving the LGBTQ community in outpatient care. RESULTS: PDSA Cycle 3 to PDSA Cycle 4, which consisted of an education intervention for staff, showed the most consistent t-statistics. All questions have effects going in the appropriate direction and three results were statistically significant with p values < 0.05. These results indicate that the staff training was successful in improving the client experience answering SOGI questions. The pilot program established an effective model for implementing SOGI questions in this setting and will gradually be expanded to local clinics, then to the entire state-wide agency.Doctor of Nursing Practic
