Generating ambiguity in the laboratory

This article develops a method for drawing samples from which it is impossible to infer any quantile or moment of the underlying distribution. The method provides researchers with a way to give subjects the experience of ambiguity. In any experiment, learning the distribution from experience is impossible for the subjects, essentially because it is impossible for the experimenter. We describe our method mathematically, illustrate it in simulations, and then test it in a laboratory experiment. Our technique does not withhold sampling information, does not assume that the subject is incapable of making statistical inferences, is replicable across experiments, and requires no special apparatus. We compare our method to the techniques used in related experiments that attempt to produce an ambiguous experience for the subjects.ambiguity; Ellsberg; Knightian uncertainty; laboratory experiments; ignorance; vagueness JEL Classications: C90; C91; C92; D80; D81

Socio-Economic Status, Health Shocks, Life Satisfaction and Mortality: Evidence from an Increasing Mixed Proportional Hazard Model

The socio-economic gradient in health remains a controversial topic in economics and other social sciences. In this paper we develop a new duration model that allows for unobserved persistent individual-specific health shocks and provides new evidence on the roles of socio-economic characteristics in determining length of life using 19-years of high-quality panel data from the German Socio-Economic Panel. We also contribute to the rapidly growing literature on life satisfaction by testing if more satisfied people live longer. Our results clearly confirm the importance of income, education and marriage as important factors in determining longevity. For example, a one-log point increase in real household monthly income leads to a 12% decline in the probability of death. We find a large role of unobserved health shocks, with 5-years of shocks explaining the same amount of the variation in length of life as all the other observed individual and socio-economic characteristics (with the exception of age) combined. Individuals with a high level of life satisfaction when initially interviewed live significantly longer, but this effect is completely due to the fact that less satisfied individuals are typically less healthy. We are also able to confirm the findings of previous studies that self-assessed health status has significant explanatory power in predicting future mortality and is therefore a useful measure of morbidity. Finally, we suggest that the duration model developed in this paper is a useful tool when analysing a wide-range of single-spell durations where individual-specific shocks are likely to be important.education, marriage, life satisfaction, shocks, mortality, duration analysis

Diamond platforms for nanoscale photonics and metrology

Observing and controlling solid state quantum systems is an area of intense research in quantum science today. Such systems offer the natural advantage of being bound into a solid device, eliminating the need for laser cooling and trapping of atoms in free space. These solid state "atoms" can interface directly with photonic channels designed to efficiently couple into larger networks of interacting quantum systems. With all of the tools of semiconductor fabrication technology available, the idea of scalable, chip-based quantum networks is a tantalizing prospect.Physic

Tangerqengiaraucaraq (being present)

Thesis (Ph.D.) University of Alaska Fairbanks, 2018This qualitative, participatory action research was conducted to investigate the following research questions: What are the attitudes of the teachers in ESDY 630: Language, Culture and Teaching in Secondary Schools class toward culturally responsive teaching and learning? How does participating in ESDY 630: Language, Culture and Teaching in Secondary Schools class affect attitudes of the educators? How do educators co-construct the relationship between standards and culturally responsive teaching and learning? Data were gathered from five pre-service teachers in the University of Alaska Anchorage Master of Arts in Teaching program in a 2-credit Language, Culture, and Teaching in Secondary Schools class. Data consisted of class recordings, student artifacts, teacher researcher journal and informal interviews. The data were analyzed using Constructive Grounded Theory framework. Tangerqengiaraucaraq (Being Present) emerged as a key concept based on the themes identified in the data: Becoming Aware, Adapting, Knowing Self and Others, and Building Relationship. The qasgiq (Indigenous community center) is proposed as a model to support ways to become a culturally responsive teacher.Chapter 1 Ikirun (Introduction) -- 1.1 Introduction -- 1.2 Yuvrirnaurqucia (Need for the Study) -- 1.3 Apyutenka (Research Questions) -- 1.4 Aperyarat Taikaniutait-llu (Definitions) -- 1.5 Arcaqaucia Yuvrillma (Significance of the Study).

Estimating The Causal Effect of Income on Health: Evidence from Post Reunification East Germany

In this paper we investigate if there was a causal effect of changes in current and 'permanent' income on the health of East Germans in the years following reunification. Reunification was completely unanticipated and therefore can be seen as a providing some exogenous variation, which resulted in a substantial increase in average household incomes for East Germans. Our data source is the German Socio-Economic Panel (GSOEP) between 1991 and 1999, and we fit both random and fixed-effects estimators to our ordinal health measures. Whilst the exogeneity of reunification allows us to establish the causality between income and health, the fixed-effects methodology additionally enables us to control for individual unobservable heterogeneity such as parental background and general attitudes to health. We also provide new evidence on how major life-events impact on health, and we pay close attention to the issue of panel attrition, given that there might be endogenous exits from the panel if the unhealthy are more likely to drop out of the sample. Using cross-sectional variations in income and health we find evidence of a significant positive effect of current income on health. However, after controlling for heterogeneity and using a new decomposition of the fixed-effects estimates, we find no evidence that increased income leads to improved health. This is the case with respect to current income and a measure of 'permanent' income and two alternative definitions of health. We also find no evidence of an effect of regional income on health.Income, Health, German Reunification, Panel Data, Attrition
