Investigation and quality assessment of the Past Weather Code from the Integrated Surface Database

Quantitative SYNOP Code weather variables such as rainfall amount, although of high societal and environmental importance, are frequently subject to recording errors and inhomogeneities resulting in uncertain conclusions. Here we assess the viability of the more qualitative Past Weather Code (PWC) for its use in robust climate analysis in the belief that it is less prone to both random and systematic errors. The Past Weather Code data, from a selection of the National Oceanographic and Atmospheric Administration’s Integrated Surface Database (ISD) (4731 sufficiently long stations), is quality assessed by searching for inhomogeneities in station PWC time series, removing the offending stations and averaging the remaining stations into a global gridded dataset. PWCs 6 (Rainfall), 7 (Snowfall) and 9 (Thunderstorms) are found to robustly exhibit seasonal features, e.g. the Indian monsoon and peak Northern Hemispheric winter snowfall. Precipitation responses to the North Atlantic Oscillation are also detected in winter PWC 6 data over Europe

This resource center consists of a collection of the latest sources of information on strategies for successful career matching and job searching, in addition to a computer with bookmarked websites for easy navigation of selected helpful websites and informative articles

Intertemporal income shifting and the taxation of business owner-managers

We use newly linked tax records to show that the large responses of UK company owner-managers to personal taxes are due to intertemporal income shifting and not to reductions in real business activity. Around half of this shifting is short-term and helps prevent volatile incomes being taxed more heavily under progressive personal taxes. The remainder reflects systemic profit retention over long periods to take advantage of lower tax rates, including preferential treatment of capital gains. We find no evidence that this tax-induced retention increases business investment. It does, however, substantially reduce the tax revenue raised from high income business owners

Clinical handovers between pre-hospital and hospital staff:Literature review

Background: Clinical handover plays a vital role in patient care and has been investigated in hospital settings, but less attention has been paid to the interface between prehospital and hospital settings. This paper reviews the published research on these handovers. Methods: A computerised literature search was conducted for papers published between 2000 and 2013 using combinations of terms: ‘handover’, ‘handoff’, ‘prehospital’, ‘ambulance’, ‘paramedic’ and ‘emergency’ and citation searching. Papers were assessed and included if determined to be at least moderate quality with a primary focus on prehospital to hospital handover. Findings: 401 studies were identified, of which 21 met our inclusion criteria. These revealed concerns about communication and information transfer, and themes concerning context, environment and interprofessional relationships. It is clear that handover exchanges are complicated by chaotic and noisy environments, lack of time and resources. Poor communication is linked to behaviours such as not listening, mistrust and misunderstandings between staff. While standardisation is offered as a solution, notably in terms of the use of mnemonics (alphabetical memory aids), evidence for benefit appears inconclusive. Conclusions: This review raises concerns about handovers at the interface between prehospital and hospital settings. The quality of existing research in this area is relatively poor and further high-quality research is required to understand this important part of emergency care. We need to understand the complexity of handover better to grasp the challenges of context and interprofessional relationships before we reach for tools and techniques to standardise part of the handover process

A Systematic Reveiw of Student Self-Report Instruments That Assess Student-Teacher Relationships

Background: A large body of survey-based research asserts that the quality and strength of student-teacher relationships (STRs) predict a host of academic and nonacademic outcomes; however, advances in survey design research have led some to question existing survey instruments’ psychometric soundness. Concurrently, qualitative research on STRs has identified important developmental and sociocultural variation in the ways students define, understand, and react to relationships with their teachers. The questions raised by survey methodologists, together with the conceptual elaboration of STRs, suggest that survey instruments used to assess STRs are due for a systematic review. Purpose/Research Questions: This review of survey instruments examines the strengths and shortcomings of existing measures of STRs. Specifically, we ask: How do student self-report survey instruments assess STRs? We examined the extent to which these instruments reflect current survey design principles and existing knowledge about how STRs work, particularly for adolescents. Research Design, Data Collection, and Analysis: A systematic search of peer-reviewed journal articles that (a) focused on North American middle- or high-school students, (b) linked STRs to student outcomes, and (c) used a student-report measure of STRs yielded 66 studies for which we could obtain the full instrument. Instruments were analyzed using a literature-informed protocol and an iterative process that resulted in strong inter-rater agreement. We used tables and matrices to examine patterns, themes, and outliers in our coded data. Findings: The 66 studies varied considerably with respect to how they operationalized STRs and how they addressed the validity of their instruments. Similar survey items were used to measure different constructs, and constructs with the same names were measured inconsistently across studies. Many instruments were limited by (a) items that included words with ambiguous meanings, (b) inconsistent identification of instruments’ focal students and teachers across instruments, and (c) the use of negatively worded items to measure STRs’ strength. Conclusions and Recommendations: If STR research is to meet its promise to guide and inform teachers’ efforts to develop and sustain effective relationships with their students, the field needs to properly identify those behaviors that make a difference for different students and those that do not. The next generation of student-report STR survey instruments requires more stringent attention to construct specification and validity, as well as to item generation (specifically, language use), in order to most effectively measure and identify aspects of STRs that affect student performance and well-being
