Why did British electricity prices fall after 1998?

In an attempt to reduce high electricity prices in England and Wales the government has tried to encourage an increase in generation capacity, introduced a more competitive market structure and changed the market rules. Our econometric analysis on monthly data from April 1996 to March 2002 implies support for two conflicting hypotheses. On a static view, increases in competition and the capacity margin were responsible for the fall in prices, while changes in the trading rules had little impact. If generators had been tacitly colluding before NETA, however, the impending change in market rules might have changed their behaviour a few months before the abolition of the Pool. Regressions representing this hypothesis imply that NETA was responsible for a significant part of the reductions in prices after 1998

Reimagining measurement: Enhancing social impact through better monitoring, evaluation, and learning

Social sector organizations tackle some of the world's most difficult and complex challenges on a daily basis. And, just as in other industries, getting the right data and information at the right time is essential to understanding what an organization needs to achieve, whether it is doing what it set out to do, and what impact its efforts are actually having. Yet, despite marked advances in the tools and methods for monitoring, evaluation, and learning in the social sector, as well as a growing number of bright spots in practice emerging in the field, there is broad dissatisfaction across the sector about how data is -- or is not -- used.Three straightforward principles -- purpose, perspective, and alignment with other actors -- can help the social sector reinvent its approach to measuring social impact, turning data into an asset that benefits both philanthropic organizations and those they seek to help

Increasing Gambler's Ruin duration and Brownian Motion exit times

In Gambler's Ruin when both players start with the same amount of money, we show the playing time stochastically increases when the games are made more fair. We give two different arguments for this fact that extend results from \cite{Pek2021}. We then use this to show that the exit time from a symmetric interval for Brownian motion with drift stochastically increases as the drift moves closer to zero; this result is not easily obtainable from available explicit formulas for the density

Dialogue: Clarified and Reconsidered

Controversies about constitutional “dialogue” often stem from disagreement over the concept itself. The metaphor’s meaning and attendant consequences differ depending on whether it reflects the assumptions of judicial interpretive supremacy or coordinate interpretation. By combining that distinction with the contrast between weak-form and strong-form rights review, this article creates an integrated framework for clarifying dialogic variation across such jurisdictions as the United States, Canada, the United Kingdom, New Zealand, and Australia. We apply this framework most intensely to the Canadian case and bring differences between several dialogic forms—especially the difference between “clarification dialogue” and “reconsideration dialogue”—into sharper relief than is common in the literature. The classification of dialogic types revealed by the Canadian experience can, we suggest, illuminate analysis in other jurisdictions

Mapping access to health services as a strategy for planning: access to primary care for older people in regional Queensland

Australia has seen a significant increase in people aged over 65 years accessing general practice services over the last decade. Although people aged 65 years and over comprise 14% of the total population, this age demographic accounts for the largest proportion of general practitioner (GP)–patient encounters. Access to general practice is important for older Australians as the burden of chronic disease increases with age. A geographic information system, ArcGIS, was used to assess geographic access to general practice for older people residing in the regional Queensland towns of Mackay, Townsville and Cairns. Geographic units with high proportions of over 65-year-old people were spatially analysed in relation to proximity to geomapped general practices with a 2-km buffer zone. Modelling of changes in access was performed with the strategic location of a new general practice where gaps existed. Geographic access to general practice for the older population was poorest in Cairns despite a high population density. Addition of a single, strategically placed general practice in Cairns markedly improved access. Socioeconomic analysis suggested that general practices were appropriately located in areas of greatest need. Geographic information systems provide a means to map population characteristics against service locations to assist in strategic development and location of future health services

Irrigation Water Quality Sampling Guide

Understanding irrigation water quality is an important part of irrigation water management. Water quality testing begins with identifying constituents for which to test. Proper sample collection is important for characterizing a water source. This fact sheet addresses water sampling, what to sample or test, irrigation equipment concerns, pollutants, and when, where, and how to sample

The efficacy of the “Talk-to-Me” suicide prevention and mental health education program for tertiary students: a crossover randomised control trial

Despite suicide ideation being one of the most frequently reported health issues impacting tertiary students, there is a paucity of research evaluating the efficacy of preventive interventions aimed at improving mental health outcomes for students studying at two tertiary institutes. The current study evaluated the efficacy of the “Talk-to-Me” Mass Open Online Course (MOOC) in improving tertiary students’ abilities to support the mental health of themselves and their peers via a randomised controlled trial design, comparing them to a waitlist control group. Overall, 129 tertiary students (M = 25.22 years, SD = 7.43; 80% female) undertaking a health science or education course at two Western Australian universities were randomly allocated to either “Talk-to-Me” (n = 66) or waitlist control (n = 63) groups. The participants’ responses to suicidal statements (primary outcome), knowledge of mental health, generalised self-efficacy, coping skills, and overall utility of the program (secondary outcomes) were collected at three timepoints (baseline 10-weeks and 24-weeks from baseline). Assessment time and group interaction were explored using a random-effects regression model, examining changes in the primary and secondary outcomes. Intention-to-treat analysis (N = 129) at 10-weeks demonstrated a significant improvement in generalised self-efficacy for “Talk-to-Me” compared to the control group (ES = 0.36, p = .04), with only the “Talk-to-Me” participants reporting increased knowledge in responding to suicidal ideation (primary outcome). This change was sustained for 24 weeks. Findings provide preliminary evidence suggesting that the “Talk-to-Me” MOOC can effectively improve tertiary students’ mental health and knowledge of how to support themselves and others in distress.

Understanding Judicial Hierarchy, Reversals and the Behavior of Intermediate Appellate

One of the central controversies in the judicial behavior literature is the extent to which judges' ability to act according to their ideological preferences is affected by their location in the judicial hierarchy. Judges on intermediate appellate courts have different decisionmaking environments than high court judges. As a result, the goals of lower appellate court judges may differ from those of their superiors: the quest for legal accuracy may compete with the desire to pursue policy preferences. Analysis of the reversal rate of the U.S. circuit courts of appeals offers insight into the extent to which these judges balance the pressures of their own policy preferences with the desire to achieve the legally accurate result in cases they decide. Int eraction between first-level and second-level appellate courts is a subject that has garnered increasing attention over the past several years, but an opportunity to bridge disciplinary divides by integrating recent scholarly work by political scientists and legal academics has largely been missed in the process. Disagreements between the two levels of courts produce reversals of the lower court by the higher court, but the process that drives such reversal is not well-understood given its importance in maintenance of judicial organization. Particularly in systems where review by the second-level appellate court is discretionary, higher courts reverse lower courts in pursuit of making broader policy statements, so the process takes on added importance. Work that assesses decisions by high courts to grant leave to appea
