Accurate analysis of data using standardized statistical methods in scientific studies is critical to determining the validity of empirical research. Statistical formulas such as regression, uncertainty coefficient, t-test, chi square, and various types of ANOVA (analyses of variance) are fundamental to forming logical, valid conclusions. If empirical data reach significance under the appropriate statistical formula, the research hypothesis is supported. If not, the null hypothesis is supported (or, more accurately, not rejected), meaning no effect of the independent variable(s) was observed on the dependent variable(s). The outcome of empirical research using statistical hypothesis testing is never proof. It can only support a hypothesis, reject it, or do neither. These methods yield only probabilities. Among scientific researchers, empirical evidence (as distinct from empirical research) refers to objective evidence that appears the same regardless of the observer. For example, a thermometer ...

Virtual reality technology has recently had a revival with new VR-hardware being introduced to the consumer market. This can be considered a turning point in the field as it has now become more accessible and affordable to the public. Since this revival, VR-technology has been subject to multiple HCI studies, where also VR locomotion techniques have been examined. However, a majority of these studies emphasize constructive research problems with a focus on understanding the technical aspects of the interaction. New and novel VR locomotion techniques are constructed without any empirical evaluation of the human aspects to support this work. Without the knowledge of already existing issues with the interaction, there is a research gap in the current field of VR locomotion studies. To fill this research gap, we examined and compared three of the currently prevalent VR locomotion techniques; joystick, teleportation and walk in place with a focus on the user experience and usability. We examined ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Methods for voting classification algorithms, such as Bagging and AdaBoost, have been shown to be very successful in improving the accuracy of certain classifiers for artificial and real-world datasets. We review these algorithms and describe a large empirical study comparing several variants in conjunction with a decision tree inducer (three variants) and a Naive-Bayes inducer. The purpose of the study is to improve our understanding of why and when these algorithms, which use perturbation, reweighting, and combination techniques, affect classification error. We provide a bias and variance decomposition of the error to show how different methods and variants influence these two terms. This allowed us to determine that Bagging reduced variance of unstable methods, while boosting methods (AdaBoost and Arc-x4) reduced both the bias and variance of unstable methods but increased the variance for Naive

For optimizing and evaluating image quality in medical imaging, one can use visual grading experiments, where observers rate some aspect of image quality on an ordinal scale. To analyze the grading data, several regression methods are available, and this study aimed at empirically comparing such techniques, in particular when including random effects in the models, which is appropriate for observers and patients. Data were taken from a previous study where 6 observers graded or ranked in 40 patients the image quality of four imaging protocols, differing in radiation dose and image reconstruction method. The models tested included linear regression, the proportional odds model for ordinal logistic regression, the partial proportional odds model, the stereotype logistic regression model and rank-order logistic regression (for ranking data). In the first two models, random effects as well as fixed effects could be included; in the remaining three, only fixed effects. In general, the goodness of fit (AIC
Experiments with relatively high doses are often used to predict risks at appreciably lower doses. A point of departure (PoD) can be calculated as the dose associated with a specified moderate response level that is often in the range of experimental doses considered. A linear extrapolation to lower doses often follows. An alternative to the PoD method is to develop a model that accounts for the model uncertainty in the dose-response relationship and to use this model to estimate the risk at low doses. Two such approaches that account for model uncertainty are model averaging (MA) and semi-parametric methods. We use these methods, along with the PoD approach in the context of a large animal (40,000+ animal) bioassay that exhibited sub-linearity. When models are fit to high dose data and risks at low doses are predicted, the methods that account for model uncertainty produce dose estimates associated with an excess risk that are closer to the observed risk than the PoD linearization. This ...

Downloadable (with restrictions)! The study presents an empirical analysis of the relative revenue efficiency of UK universities in providing teaching and research. With government policies pressurizing the largely public-funded universities to secure efficiency in both input usage and output revenue, university producers are modelled as cost-constrained revenue maximizers. Taking explicit account of the quality of research output, the methodology uses linear programming techniques to construct nonparametric cost indirect production frontiers and to compute revenue efficiency relative to these frontiers. Revenue efficiency is then decomposed into its (output) allocative and technical components. Further analysis investigates the sources of allocative and technical inefficiencies.

N2 - Ranking and Selection has acquired an important role in the Simulation-Optimization field, where the different alternatives can be evaluated by discrete event simulation (DES). Black box approaches have dominated the literature by interpreting the DES as an oracle providing i.i.d. observations. Another relevant family of algorithms, instead, runs each simulator once and observes time series. This paper focuses on such a method, Time Dilation with Optimal Computing Budget Allocation (TD-OCBA), recently developed by the authors. One critical aspect of TD-OCBA is estimating the response given correlated observations. In this paper, we are specifically concerned with the estimator of the variance of the response ...

Systematic reviews (SRs) of the professional literature, sometimes termed the platinum standard of evidence [1], form the foundation for clinical guidelines and evidence-based health policy, thus shaping the policy agenda in medicine and public health [2, 3]. Contrary to narrative reviews, which may be biased due to non-systematic procedures for identifying original studies, SRs enjoy high credibility. Despite their popularity in recent years, enormous importance, and clear advantages over traditional reviews, it is not easy to validate the results of a given SR: there is simply no gold standard with which to compare the results. The scientific community has approached this issue by 1 - creating reporting standards [4-6]; 2 - developing tools to validate SR quality [7] and risk of bias [8]; and 3 - applying those standards and tools to published SRs [4, 9-16]. A fourth approach, made possible by the proliferation of published SRs on similar topics, is based on empirical comparisons of SR ...

This exploratory research has resulted in a framework of enablers for the development and implementation of a service charter for an integrated stroke service. It consists of seven categories of enablers containing 27 properties. The results of our research contribute to the literature on service charters, patient-centred integrated care and the implementation of innovations.. Thomassen et al. developed a Public Service Charter Implementation Framework consisting of three main clusters and ten sub-clusters of enablers. This was the first empirical research on enablers for the effective development and implementation of a service charter that focused on individual organizations. The current research has extended the knowledge on this subject by conducting research on the development and implementation of a single service charter covering an integrated care setting. The results show that the enablers are not only related to the organizational level but that there are additional enablers on the ...

Within the AI planning (AIP) community, the concept of using artificial scenarios for system evaluation is well established. The International Planning Competition (IPC) [2] is a bi-annual event which allows an empirical comparison of AIP systems from around the world. Its committees have developed seven sets of benchmark problems [2] from a wide range of domains, each containing problems of scaled complexity. The domains are taken from both current, real-world, applications of AIP and from new fields that have the potential to be effectively supported by the technology Each domain focuses on different elements of AIP capability. As stated by Edelkamp and Hoffmann [3] the objective of using these problem sets, aside from aiding in the comparative evaluation of various systems, is to highlight challenges to the community in the form of problems at the edge of current capabilities [and] to propose new directions for research. These problem sets have been shown to be invaluable for accurately ...
Pathway enrichment extensively used in the analysis of Omics data for gaining biological insights into the functional roles of pre-defined subsets of genes, proteins and metabolites. A large number of methods have been proposed in the literature for this task. The vast majority of these methods use as input expression levels of the biomolecules under study together with their membership in pathways of interest. The latest generation of pathway enrichment methods also leverages information on the topology of the underlying pathways, which as evidence from their evaluation reveals, lead to improved sensitivity and specificity. Nevertheless, a systematic empirical comparison of such methods is still lacking, making selection of the most suitable method for a specific experimental setting challenging. This comparative study of nine network-based methods for pathway enrichment analysis aims to provide a systematic evaluation of their performance based on three real data sets with different number of features
ABSTRACT Evidence suggests that the significantly higher life expectancy levels witnessed over the past centuries are associated with a lower concentration of survival times, both cross-country and over time. The purpose of this work is to study the relationships that exist among models for the evolution of survival distributions, longevity measures, and concentration. We first study relationships between concentration and cohort longevity through empirical comparisons. We then propose a family of survival models that can be used to capture such trends in longevity and concentration across survival distributions.

Although professional development is an important means of improving both teachers skills and student outcomes, there is a dearth of high quality empirical research on the efficacy of such efforts. The efficacy of the Challenging Behavior Process was assessed using a mixed method approach which included the use of pre-, post-, and follow-up surveys. The participants were preschool teachers who worked for Kamehameha Schools on the island of Oahu. The relationship of the training to teacher efficacy, learning, and transfer was assessed. The analyses determined that the training was well-designed to meet the needs of the teaching staff, participants reacted positively to the training, and participation in the training was related to positive changes in knowledge about the CB process. However, participation in the training was also related to a statistically significant decrease in teacher efficacy for teaching strategies at the time of the follow-up and a number of knowledge gaps were uncovered. ...

The JSP Program offers an ambitious program of graduate study and promotes a distinctive scholarly orientation. As in the case of other law-and-society centers, JSP approaches the study of law and its social functions from a variety of social science perspectives and methodologies. But the program equally seeks to engage traditional humanistic questions concerning the aspirations and values ascribed to the institutions of law and justice. And it aims to advance the integration of these discrete disciplinary perspectives. The programs title - Jurisprudence and Social Policy - reflects this expansive effort to link the scholarly examination of legal ideas and institutions with empirical research on issues of public policy. ...
Standard practice for the estimation of dynamic stochastic general equilibrium (DSGE) models maintains the assumption that economic variables are properly measured by a single indicator, and that all relevant information for the estimation is summarized by a small number of data series. However, recent empirical research on factor models has shown that information contained in large data sets is relevant for the evolution of important macroeconomic series. This suggests that conventional model estimates and inference based on estimated DSGE models might be distorted. In this paper, we propose an empirical framework for the estimation of DSGE models that exploits the relevant information from a data-rich environment. This framework provides an interpretation of all information contained in a large data set, and in particular of the latent factors, through the lenses of a DSGE model. The estimation involves Markov-Chain Monte-Carlo (MCMC) methods. We apply this estimation approach to a ...

BACKGROUND: Many mammals are well adapted to surviving in extremely cold environments. These species have likely accumulated genetic changes that help them efficiently cope with low temperatures. It is not known whether the same genes related to cold adaptation in one species would be under selection in another species. The aims of this study therefore were: to create a compendium of mammalian genes related to adaptations to a low temperature environment; to identify genes related to cold tolerance that have been subjected to independent positive selection in several species; to determine promising candidate genes/pathways/organs for further empirical research on cold adaptation in mammals ...

From a naturalistic perspective on mental illness, depression is often described in terms of biological dysfunctions, while a normative perspective emphasises the lived experience of depression as a harmful condition. The paper relates a conceptual analysis of depressive situation to an analysis of the lived experience of depression. As such, it predominantly aims to specify depression as a harmful condition in lights of normative perspective on mental disorder, but partially refers to empirical research, i.e. naturalistic perspective on depression, to exemplarily stress on the methodological merits and limits of relating phenomenological considerations closer to empirical research. The depressive situation is further specified with an examination of the evaluative dynamics by which individuals meaningfully relate to themselves, others and the world. These evaluative dynamics emerge out of the interplay of pre-reflective and reflective processes, which are significantly altered in depression. Such

Each week we will hold one session in the classroom and one session in the computer lab. In the classroom we will introduce concepts and review a number of important econometric tools for data analysis. In the lab we will implement these tools with data and build up software skills. By the end of the class, students will have acquired skills to manipulate data in Excel (matching datasets, pivot tables) and use Stata to run regressions and prepare results for a publication. Students will also get to read high-quality peer-reviewed articles on different topics in economics to understand how empirical results are presented and interpreted.. Important note: The language for the course is English, and this for two reasons. First, you need to build up the relevant vocabulary to read and interpret the scientific literature (which is almost exclusively in English). Second, this class prepares you for good master programs and job opportunities in international environments, where a good command of ...
This paper takes the listed companies in China from 2010 to 2015 as samples, which uses the breakpoint regression design to analyze the change of risk structure and its possible mechanism of listed companies after wearing and removing hats. The results show that the short-term solvency of listed companies deteriorates after wearing hats, and the long-term liabilities increase significantly. R&D expenditure decreased significantly, and cash flow level deteriorated. Financial leverage and comprehensive leverage increased significantly, and the total market value of the company decreased significantly, which led to a significant deterioration in the short-term financial risk structure of the company after wearing a hat.

The topic of this paper focuses on informal patient payments in Kosovo public health care system, and it includes an analysis of current anti-corruption institutions and policies as well as a description of findings from focus groups with regard to perceptions of doctors and patients about informal patient payments. The phenomenon of informal payments, similar to a number of south-east European countries, remains an intense question in Kosovo. This paper presents a small qualitative effort that tries to shed light on determinants of informal payments in the health sector of Kosovo and to identify who benefits, the characteristics and timing of payments, and the reasons for paying. The analysis derives from two focus groups that were organized with doctors and patients. The results show that informal cash payments are common for surgeries and childbirth and skipping waiting lines for diagnostic tests. Paying informally seems more likely to be a result of culture and tradition rather than ...

This paper proposes two hypotheses that urban housing prices inhibit urban labor mobility and urban high-tech industry development by introducing the extended CP model of housing prices. On this basis, using the data of the 9-city data of the Pearl River Delta from 2001 to 2015 to conduct empirical analysis and testing through the fixed-effects model, it is found that the increase of relative housing prices in cities will promote urban labor inflows and inhibit the development of urban high-tech industries. Factors such as education level, medical level, and government budget expenditure will, to a certain extent, strengthen the role of relative housing prices in promoting labor inflows and weaken the inhibition of urban housing prices on high-tech industries.

The purpose of this paper was to review the literature on leadership and safety in order to highlight possible applications to health care. There are few studies of safety leadership in health care, so it is necessary to extrapolate from the studies that have been conducted in other industrial sectors (mainly energy and manufacturing). In those sectors, there is sufficient empirical research on leadership and safety to identify a generic set of effective behaviours at three organisational levels (supervisors, middle managers, senior managers; see table 1). It has already been suggested that transformational leadership may be an appropriate model for improving patient safety in health care26 and this paper discusses several studies that apply the transformational/transactional leadership paradigm to safety research. As not all of the studies reviewed use the transformational/transactional paradigm, table 1 indicates whether the behaviours identified at each management level are transactional or ...
Popular code coverage measures, such as branch coverage, are indicators of the thoroughness rather than the fault detection capability of test suites. Mutation testing is a fault-based technique that measures the effectiveness of test suites for fault localisation. Unfortunately, use of mutation testing in the software industry is rare because generating and running vast numbers of mutants against the test cases is time-consuming and difficult to do without an automated, fast and reliable tool. Our objective is to present an innovative approach to mutation testing that takes advantage of a novel aspect-oriented programming mechanism, called pointcut and advice, to avoid multiple compilation of mutants and, therefore, to speed up mutation testing. An empirical comparison of the performance of the developed tool, called Judy, with the MuJava mutation testing tool on 24 open-source projects demonstrates the value of the presented approach. The results show that there is a statistically significant (t(23)

Background This paper provides an overview of the empirical research on equity theory amongst staff working in services for individuals with intellectual disabilities (ID). Method Relevant articles were identified by using the PsycINFO computerised database and by conducting manual searches of reference lists. Results Six studies were identified and reviewed. Staff often report that they feel under-benefited in their work-based relationships. Associations were found between staff equity perceptions and staff outcomes such as burnout, absenteeism and intention to leave. Conclusion Previous research findings on staff outcomes are discussed within the context of equity theory. The implications of staff equity perceptions for ID services are discussed and possible directions for future research are forwarded. It is suggested that equity theory may have some utility as a theoretical starting point from which to develop a comprehensive theory to integrate various strands of research on ...
Recent research on entrepreneurship has focused largely on macro-level environmental forces. Although researchers adopting this focus have rightly criticized much of the existing empirical research on the role of human motivation in entrepreneurship, we believe that the development of entrepreneurship theory requires consideration of the motivations of people making entrepreneurial decisions. To provide a road map for researchers interested in this area, we discuss the major motivations that prior researchers have suggested should influence the entrepreneurial process, as well as suggest some motivations that are less commonly studied in this area. In addition to outlining the major reasons for exploring these motivations, we identify the major weaknesses that have limited the predictive power of previous research on this topic. We offer explicit solutions for future research to adopt to overcome these problems.
This study was undertaken to explore the possible relationship between clinicians training in neutrality at Smith College School for Social Work and their enduring practice ideals with respect to neutrality. Grounded in the theoretical literature regarding models of psychodynamic therapeutic change, this research project sought to describe the role of neutrality in contemporary clinical practice, addressing a gap in comprehensive empirical research on this topic. Research data was collected from 224 alumni who graduated from Smith College School for Social Work (SCSSW) during the past 30 years and are currently practicing in the field of mental health. Participants completed an online survey designed to assess their training in neutrality at SCSSW, factors that have contributed to adaptation of participants practice stance since graduation, and the role of neutrality in participants current clinical work. The survey incorporated questions from an established survey measure, as well as questions
BACKGROUND:There is limited empirical research on the underlying gender inequity norms shaping gender-based violence, power, and HIV risks in sub-Saharan Africa, or how risk pathways may differ for men and women.
Hutchin Hill Capital has snapped up the latest Nobel prize in economics winner, even before it knew he had won the award.. New York-based Hutchin Hill told investors in September that New York Universitys Thomas Sargent had signed on as an adviser to the $1.5 billion firm, The New York Times reports. The following month, Sargent and Princeton Universitys Christopher Sims were announced as the winners of the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for their empirical research on cause and effect in the macroeconomy.. Professors Sargent and Sims will formally receive the award next month in Stockholm.. We believe working with Professor Sargent will be of significant value in developing a deeper understanding of the macroeconomic background that has had such a large impact on risk sentiment and asset prices, especially during the past three years, Hutchin Hill wrote.. Hutchin Hill was founded three-and-a-half years ago by former SAC Capital Advisors manager Neil ...
In meta-analyses, a CI is inadequate for clinical decision-making because it only summarises the average effect for the average study. The prediction interval is more informative as it shows the range of possible effects in relation to harm and clinical benefit thresholds. While we have focused on the situation where the separating threshold is the null, a different threshold may be considered. For example, in the prediction interval framework, one can calculate the probability that an effect is larger than B, where B may be a clinically meaningful effect (if the treatment benefit is less than B, then it is felt not to be worth it). A narrow prediction interval that lies completely on the beneficial side of a clinically relevant threshold increases confidence in an intervention. A broad prediction interval may indicate the existence of settings where the treatment has a suboptimal and possibly even harmful effect. In more than 70% of statistically significant meta-analyses of the Cochrane ...
BACKGROUND: Electronic health records (EHRs) have the potential to facilitate performance measurement for acute conditions.. OBJECTIVE: To evaluate the reliability and feasibility-of-use of a performance measure set for community-acquired pneumonia in an ambulatory EHR.. DESIGN: Retrospective, cross-sectional electronic chart review.. SETTING: Primary Care Clinics.. PATIENTS: Adults with an administrative claims diagnosis of pneumonia during a 14-month period.. MEASUREMENTS: Two reviewers independently examined data in the EHR to determine if (1) the encounter was a visit for acute pneumonia; (2) there was documentation for each of 12 performance measures; and (3) such information was in coded form.. RESULTS: Of 688 encounters with a claim diagnosis of pneumonia, 210 (31%) were identified by either reviewer as a primary care acute pneumonia visit. The 2 reviewers agreed that 198 encounters to 71 different clinicians were visits for acute pneumonia [kappa, 0.96; 95% confidence interval (CI), ...

Introduction: This study investigates the efficiency gains of integrated care models in Switzerland, since these models are regarded as cost containment options in national social health insurance. These plans generate much lower average health care expenditure than the basic insurance plan. The question is, however, to what extent these total savings are due to the effects of selection and efficiency.. Methods: The empirical analysis is based on data from 399,274 Swiss residents that constantly had compulsory health insurance with the Helsana Group, the largest health insurer in Switzerland, covering the years 2006 to 2009. In order to evaluate the efficiency of the different integrated care models, we apply an econometric approach with a mixed-effects model.. Results: Our estimations indicate that the efficiency effects of integrated care models on health care expenditure are significant. However, the different insurance plans vary, revealing the following efficiency gains per model: ...
Prediction intervals on Deming regression are a major new feature in the Analyse-it Method Validation Edition version 4.90, just released.. A prediction interval is an interval that has a given probability of including a future observation(s). They are very useful in method validation for testing the commutability of reference materials or processed samples with patient samples. Two CLSI protocols, EP14-A3: Evaluation of Commutability of Processed Samples and EP30-A: Characterization and Qualification of Commutable Reference Materials for Laboratory Medicine both use prediction intervals.. We will illustrate this new feature using an example from CLSI EP14-A3:. 1) Open the workbook EP14-A3.xlsx.. 2) On the Analyse-it ribbon tab, in the Statistical Analysis group, click Method Comparison and then click Ordinary Deming regression.. The analysis task pane opens.. 3) In the X (Reference / Comparative) drop-down list, select Cholesterol: A.. 4) In the Y (Test / New) drop-down list, select ...
Bibliography Review. Empirical research has extensively used patents for the measurement of innovation, taking advantage of their important advantages. However, empirical research has also highlighted their limitations when used in economic analysis. In relation to their advantages, patents are linked to and can measure both inventions and innovations. As a measure of inventions patents have a close (if not perfect) link to inventions (OECD 2009).. Patents cover a broad range of techniques, extending now to biotechnology and software, with first extensions towards services-related inventions (so-called business methods) (OECD 2005). Patents enable researchers to study and to assess different features of innovative processes. On the basis of the huge literature on patents, we can highlight some major research directions that have been examined through patents, such as the level of inventive activity, studied by Griliches (1990), Lanjouw and Mody (1996), Cohen et al. (2000) and Popp (2005). ...
Purpose - The purpose of this paper is to present the current empirical research examining communication, compensation and logistics as elements of product crises management in retailing. Design/methodology/approach - The advantages and disadvantages of these three elements of crises response strategies are juxtaposed drawing on relevant empirical research. For each element of crises response the major findings of research are summarized and shown how it relates to crisis management. Needs for further research that would be necessary to solidify recommendations to retail managers are derived. Findings - The investigation finds that both communicative and compensatory response elements as well as the retailers logistics can positively influence evaluations of customers directly and indirectly affected by product problems thus enhancing brand equity. This in turn will serve to increase consumers trust in the retailer that could win him new customers and generally benefit his reputation. Research ...
Online gambling has been legalized in France in 2010. Licenses are issued to gambling operators who demonstrate their ability to respect the legal framework (security, taxation, consumer protection, etc.). The preventive measures to protect vulnerable gamblers include an obligation to provide online gambling moderators. These moderators should allow gamblers to limit their bets, exclude themselves from the website for 7 days, and consult the balance of the gamblers account at any time. However, there are only a few published reports of empirical research investigating the effectiveness of Internet-based protective measures implemented by French law. Moreover, no empirical research has yet studied the impact of bonuses on gambling behaviors. This research is an experimental randomized controlled trial, risk prevention targeted. The research is divided into four sub-studies depending on the studied moderator: limiting bonuses, self-exclusion, self-limitation and information. The study sample consists of

With the application of the studys selection criteria, 15 eligible publications were included in the review; these were indexed in three
This paper reports the findings from original empirical research that was designed in order to test three hypotheses. These hypotheses were formed as a result of critical analyses of popular literature in the sociology of gender and music. These hypotheses are: 1. The sex or gender of a composer is identifiable from the musical content of a composition; 2. Perception of gendering of music is related to the sex of the listener; 3. Musical sounds, or the organisation of sounds within a composition, infer sex or gender characteristics. An original empirical research framework was developed in order to test these hypotheses, mainly comprising a composer-sex attribution task for a bespoke listening sequence. The results suggest that gendered information is not represented in the gestures, structures and narratives of a musical composition; no codes are embedded in music by composers that might operate as hidden signifiers of gender; any gendered impressions experienced by a listener are imposed onto ...

While exploring and assessing vector-borne disease transmission models that might inform us about CHIKV ecology, we noted that true, first-principles transmission models have been developed for a limited suite of vector-borne diseases, particularly malaria and dengue (e.g., [43, 44]), and that models for other vector-borne disease systems have, for the most part, simply been adapted from these base models. Coarse scale predictions based on such transmission models will thus be limited in their applicability to other, more novel, surveillance-limited, large geographic-range, and less-well-studied disease systems such as CHIKV. We were particularly concerned about the effects of parameter selection for these models and their extrapolation to continental extents. Classic disease transmission models are a powerful tool with which to understand epidemics at the population level (e.g., SIR models; [45]), but they require parameters that may be difficult to estimate for a vast diversity of ...
Prolonged waiting times for elective treatment have long been considered a serious problem of the Norwegian health care system. Overall waiting times have, due to both supply and demand reforms, dropped significantly over recent years. Despite the positive development, many patients still face substantial waiting times. The analysis provides support for claiming that a policy of combining patient choice of hospital with the removal of geographical restrictions on referrals may contribute to the reduction in waiting times for individual elective patients. The main results of the empirical analyses were found to be robust over different statistical model specifications. Patients who chose to move hospitals benefit the most. They spend about 11 weeks less, on average, waiting for hospital treatment than those who neither chose nor moved. The results corroborate with the results of a few previous empirical analyses, like The London Patient Choice Project. There, a reduction in waiting times for all ...
This study assessed farmers’ perception of climate change, estimated the determinants of, and evaluated the relationship among adaptation practices using the multivariate probit model. A survey in 300 agricultural households was carried out covering 10 sample districts considering five agro-ecological zones and a vulnerability index. Four adaptation choices (change in planting date, crop variety, crop type and investment in irrigation) were deemed as outcome variables and socioeconomic, demographic, institutional, farm-level and perceptions variables were deployed as explanatory variables. Their marginal effects were determined for three climatic variables—temperature, precipitation and drought. Age, gender and education of head of household, credit access, farm area, rain-fed farming and tenure, are found to be more influential compared to other factors. All four adaptation-options are found to be complimentary to each other. Importantly, the intensity of impact of dependent variables in

In this book, there are 25 chapters, each of which is an empirical analysis of either statewide data such as Texas or national data such as the Early Childhood Longitudinal Study-Kindergarten. Each chapter contains an empirical analysis of contemporary issues in education today such as inequities in discipline consequences by student ethnicity/race, economic status, poverty, and gender; persistence rates of Black and Hispanic students in community colleges; academic achievement performance differences by ethnicity/race, economic status, and gender; and college-readiness rates of students ...
This paper aims to develop an alternative framework for empirical analysis of regional economic growth. We apply our proposed method to analyzing the Total Factor Productivity (TFP) changes in regional economies and structural characteristics among the regions in Japan. Conventional approaches to empirical analysis of regional economic growth are insufficient for an appropriate description of the complicated behavior of TFP. Accordingly, we assume that TFP is a time-varying parameter and estimate it using a Bayesian method that employs a smoothness priors approach. Compared with conventional approaches, this application of the Bayesian method facilitates a more detailed and sophisticated analysis of TFP. A major finding of the analysis is a significant change in the TFP trends of the Japanese economy, beginning around the time of the first oil shock. Furthermore, our analytical results suggest a meaningful direction for government policies to promote economic growth in Japan. ,br,. ...
