Outcomes from use of an evidence-based practice guideline

The aim of evidence-based guidelines is primarily to improve patient outcomes without adding to the existing cost of care because both payers and policymakers want to identify health care costs that do not result in benefit to the patient. The purpose of the reported project was to generate a practice guideline for the treatment of uncomplicated acute cystitis in a female population, to determine the extent to which the guideline would be used by providers and to measure the cost and quality of outcomes from its use. A retrospective chart review was used to gather pre-guideline practice and cost data. Measurements included the type, frequency, and duration of antibiotic therapy and the use of urine cultures and both complications and routine followup visits. The implementation of an outpatient practice guideline resulted in a significant change in antibiotic prescribing and a trend toward a change in ordering cultures and clinic followup. There was also a significant decrease in treatment costs.     

Royalty Rates and Upfront Fees in Share Contracts: Evidence from Franchising

This article provides evidence on the determinants of royaltiesand upfront fees in share contracts by examining how state franchisetermination laws affect franchise contracts. The results areconsistent with the joint hypothesis that the two-sided moralhazard model explains the terms in franchise contracts and thattermination laws increase the relative importance of franchisoreffort (due to the extra effort that is required to controlsystem quality). I find that franchise companies that are headquarteredin termination-law states charge significantly higher royaltyrates than companies headquartered in other states (around 1%higher). Correspondingly, the initial franchise fees are lowerfor companies headquartered in termination states. Overall,franchisees appear to pay a higher price for franchises in stateswith protection laws. Consistent with a basic tenet of law andeconomics, price adjustments appear to offset at least someof the transfers that would otherwise be implied by the laws.     

Regulatory Institutions And Structures

This article presents a legal perspective on regulatory institutions, procedures and processes. Analysis of legal instruments examines justifications for regulatory interventions, and considers the inadequacies of private law remedies to instances of market failure (such as monopolies, inadequate or asymmetric information, externalities and co–ordination problems). A distinction is drawn between social and economic regulation: the former deals with such matters as health and safety, and environmental and consumer protection; and the latter is needed where there is insufficient competition. Instruments of social regulation include prior approval, mandatory standards and information disclosure. A range of instruments of economic regulation is also assessed, including competition law, public ownership, price and quality regulation, and competitive public franchising. Analysis of regulatory processes focuses on regulatory rule–making, delegated regulation and self–regulation. Particular weight is given to different forms of accountability—financial, procedural and substantive—which draws attention to the significance of the public interest dimension of regulatory systems.     

Monte Carlo Analysis of Score Test-Based Corrections in the Presence of Time-Varying Covariates within the Log-Hazard

Corrections based on the score test for neglected heterogeneity do not appear to have been used previously in the presence of time-varying covariates. This paper uses Monte Carlo analysis to evaluate, for a grouped hazard framework constructed for an empirical application, the efficacy of such corrections.

An additive property of weak records from geometric distributions

Let $\{W_m\}{_{m\ge 1}}$ be the sequence of weak records from a discrete parent random variable, $X$ , supported on the non-negative integers. We obtain a new characterization of geometric distributions based on an additive property of weak records: $X$ follows a geometric distribution if and only if for certain integers, $n,\, s\ge 1, W_{n+s}\stackrel{d}{=}W_n+W^{\prime }_s$ , with $W^{\prime }_s$ independent of $W_n$ and $W^{\prime }_s\stackrel{d}{=} W_s$ .     

Assessing job crafting competencies to predict tradeoffs between competing outcomes

We introduce the job crafting competency construct and apply it to predict tradeoffs between competing outcomes that are inherent in job crafting, like performance and well-being or engagement and withdrawal. Job crafting competencies are the clusters of individual knowledge, skills, and abilities that are necessary to achieve personal objectives through effective job crafting problem-solving. We create a framework of job crafting competencies consisting of comprehensive/simplistic heuristic information use and approach/avoidance problem-solving skills. In Study 1, we operationalize competencies as profiles demonstrated through an aptitude-oriented assessment that predicts differences in outcomes. Five distinct profiles emerged in a sample of 174 workers. The high-volume analytic problem-solving profile was associated with higher performance and strain, while the ambivalent acquiescence profile was associated with lower performance and strain. The practical problem-solving profile minimized tradeoffs between performance and strain. Rapid problem-solving and low-volume analytic problem-solving profiles were variants in between these other patterns. Study 2 used a survey of 323 workers to support the uniqueness of the five competencies, and their relationships with approach/avoidance job crafting, engagement, and withdrawal. The research identifies a new job crafting individual difference (job crafting competencies) to delineate outcomes and tradeoffs according to unique competency profiles.     

Karl Pearson—The Scientific Life in a Statistical Age by Theodore M. Porter: A Review

Porter presents an excellent account of the young Karl Pearson and his extraordinarily varied activities. These ranged from the Cambridge Mathematical Tripos Exams to German history and folklore, and included free thought, socialism, the woman's question, and the law. Returning to science, Pearson produced the famous Grammar of Science . He decided on a career in statistics only at age 35. Porter emphasizes Pearson's often acrimonious but largely successful battles to show the wide applicability and importance of statistics in many areas of science and public affairs. Eugenics became a passion for Pearson. Avoiding all formulas Porter fails to give any concrete ideas of even Pearson's most important contributions to statistical theory. We try to sketch these here.     

Developing a framework for network and cluster identification for use in economic development policy-making

Drawing on extensive academic research concerning clusters and networks, this paper seeks to create a framework capable of reviewing and monitoring different aspects of clusters and networks on an ongoing basis. The nine-element framework allows evaluation of the structures and processes for the eight basic cluster types identified from the literature. The use of this framework as a complimentary tool to the Multi-sectoral Qualitative Analysis (MSQA) methodology is then demonstrated using three examples (the construction, hardwood timber and higher education sectors). The data was gathered from three sets of key stakeholders (government, institutions and industry) provided from a recent study funded by the Welsh Assembly Government's Small Grants Research Programme. These cases illustrate the use of the framework in helping to generate the initial information necessary for subsequent cluster development policy (within overall regional economic development) by government to occur. The framework provides tools for reviewing and monitoring individual sectors. Information captured within the framework can also help in ameliorating problems in sectors likely to decline further. The need for further development research is also identified. Specifically at the level of the firm and network, there is a need to generate a more detailed framework of analysis of factors that contribute to successful processes of network management, learning and innovation, from which more detailed policy could be enacted in future.
