Assessment timing: student preferences and its impact on performance

Students on a first year undergraduate economics module were given the choice of when to sit their first assessment in the subject in order to determine both preferences over assessment timing, and the impact of timing on performance. Clear preferences of having this option were shown (only 2% of students stated to be indifferent) with those more comfortable and engaged in the module electing to take an earlier sitting of the assessment. Those who took the early test performed better on average compared to those who took it later, however, after controlling for attendance, there was no statistical link. There was, however, evidence that a later first assessment caused lower attendance and moreover, evidence of a legacy effect of this timing where the out-performance of the early cohort grew over later tests, which all students took at the same time

SOME EMPIRICAL METHODS OF ESTIMATING ADVERTISING EFFECTS IN DEMAND SYSTEMS: AN APPLICATION TO DRIED FRUITS

Two different methods of incorporating advertising effects into Almost Ideal Demand Systems (AIDS) are presented. Both advertising schemes are designed to allow theoretical restrictions to hold globally rather than at particular sample points. The models are estimated for California figs, prunes, and raisins. Empirical results indicate that generic advertising effects for these three dried fruits are generally weak when compared to price and total expenditure effects. Estimated cross-commodity effects also are relatively small except for the negative effect of raisin advertising on the quantity of prunes demanded.Demand and Price Analysis, Marketing,

Value Stream Analysis and Mapping for Product Development

This paper explores the concept of Value Stream Analysis and Mapping (VSA/M) as applied to Product Development (PD) efforts. Value Stream Analysis and Mapping is a method of business process improvement. The application of VSA/M began in the manufacturing community. PD efforts provide a different setting for the use of VSA/M. Site visits were made to nine major U.S. aerospace organizations. Interviews, discussions, and participatory events were used to gather data on (1) the sophistication of the tools used in PD process improvement efforts, (2) the lean context of the use of the tools, and (3) success of the efforts. It was found that all three factors were strongly correlated, suggesting success depends on both good tools and lean context. Finally, a general VSA/M method for PD activities is proposed. The method uses modified process mapping tools to analyze and improve process

Fiscal space and the procyclicality of fiscal policy: the case for making hay while the sun shines

Utilizing data from 133 countries over the period 1950-2014, we identify fiscal space - the ability to pursue active fiscal policy without undermining fiscal sustainability - as a key factor underlying the cyclicality of fiscal policies. We find that less fiscal space induces greater fiscal procyclicality; and the reduction in fiscal space in high income countries in the post-global financial crisis period prevented these economies from adopting countercyclical fiscal policies. We also show that this relationship is non-linear such that countries in the bottom tail of the fiscal space distribution need to make significant improvements before they are able to perform countercyclical policy. Taken together with the increasingly dominant role of fiscal action in downturns, as is highlighted in the context of the responses to the Covid-19 crisis, these findings clearly indicate the importance of building fiscal space in good times to provide capacity for countercyclical policy in bad times

Which cuff should I use? Indirect blood pressure measurement for the diagnosis of hypertension in patients with obesity: a diagnostic accuracy review.

OBJECTIVE: To determine the diagnostic accuracy of different methods of blood pressure (BP) measurement compared with reference standards for the diagnosis of hypertension in patients with obesity with a large arm circumference. DESIGN: Systematic review with meta-analysis with hierarchical summary receiver operating characteristic models. Bland-Altman analyses where individual patient data were available. Methodological quality appraised using Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS2) criteria. DATA SOURCES: MEDLINE, EMBASE, Cochrane, DARE, Medion and Trip databases were searched. ELIGIBILITY CRITERIA: Cross-sectional, randomised and cohort studies of diagnostic test accuracy that compared any non-invasive BP tests (upper arm, forearm, wrist, finger) with an appropriate reference standard (invasive BP, correctly fitting upper arm cuff, ambulatory BP monitoring) in primary care were included. RESULTS: 4037 potentially relevant papers were identified. 20 studies involving 26 different comparisons met the inclusion criteria. Individual patient data were available from 4 studies. No studies satisfied all QUADAS2 criteria. Compared with the reference test of invasive BP, a correctly fitting upper arm BP cuff had a sensitivity of 0.87 (0.79 to 0.93) and a specificity of 0.85 (0.64 to 0.95); insufficient evidence was available for other comparisons to invasive BP. Compared with the reference test of a correctly fitting upper arm cuff, BP measurement at the wrist had a sensitivity of 0.92 (0.64 to 0.99) and a specificity of 0.92 (0.85 to 0.87). Measurement with an incorrectly fitting standard cuff had a sensitivity of 0.73 (0.67 to 0.78) and a specificity of 0.76 (0.69 to 0.82). Measurement at the forearm had a sensitivity of 0.84 (0.71 to 0.92) and a specificity 0.75 of (0.66 to 0.83). Bland-Altman analysis of individual patient data from 3 studies comparing wrist and upper arm BP showed a mean difference of 0.46 mm Hg for systolic BP measurement and 2.2 mm Hg for diastolic BP measurement. CONCLUSIONS: BP measurement with a correctly fitting upper arm cuff is sufficiently sensitive and specific to diagnose hypertension in patients with obesity with a large upper arm circumference. If a correctly fitting upper arm cuff cannot be applied, an incorrectly fitting standard size cuff should not be used and BP measurement at the wrist should be considered

Benchmarking leads to a dynamic of constant growth in university leaders' pay

Based on an analysis of ten years of pay data, Michael W. Gmeiner, Richard McManus and Adelina Gschwandtner shed light on the complex process used to determine salaries for top university executives in the UK and show how benchmarking against peer institutions drives growth in pay packages for Vice Chancellors (VCs)
