Reading Is, Like, You Know, Sooooo Gross!
“Huge Decline in Book Reading” ran one headline. “Cultural Atrophy!” read another. “Study Links Drop in Test Scores to a Decline Spent in Reading” ran one for the “Duh!” award. “Americans are Closing the Book on Reading” said one, vying for the pun-acious trophy
Stop the Presses!
Last month a new study commissioned by the British Library and the Joint Information Systems Committee (JISC) issued one of those “Duh!” reports. The new study (available here http://www. bl.uk/news/pdf/googlegen.pdf) found that the “Google Generation,” or those brought up by computer wolves, is not very Web-literate
Civil conflict, federalism and strategic delegation of leadership
This article analyzes negative externalities that policymakers in one region or group may impose upon the citizens of neighboring regions or groups. These externalities may be material, but they may also be psychological (in the form of envy). The latter form of externality may arise from the production of 'conspicuous' public goods. As a result, decentralized provision of conspicuous public goods may be too high. Potentially, a centralized legislature may internalize negative externalities. However, in a model with strategic delegation, we argue that the median voter in each jurisdiction may anticipate a reduction in local public goods supply and delegate to a policymaker who cares more for public goods than she does herself. This last effect mitigates the expected benefits of policy centralization. The authors' theory is then applied to the setting of civil conflict, where they discuss electoral outcomes in Northern Ireland and Yugoslavia before and after significant institutional changes that affected the degree of centralization. These case studies provide support for the authors' theoretical predictions
Audit of the diagnosis and management of adult obesity in a Maltese general practice
Obesity is an escalating health problem all over the world. Unfortunately, Malta lies on the upper end of the spectrum of mean population BMI (body-mass index). Family doctors are well placed to identify cases of obesity and offer health education, medication, follow-up and referral when necessary to help their clients lose weight. They can also help prevent obesity and its complications. The authors, who work in the southern harbour area of Malta, carried out an audit of the diagnosis and management of adult obesity within their Group Practice during the year 2010. The performance of the Practice vis-Ă -vis obesity in adults is compared to the standards set by the European Practice Guidelines for the Management of Obesity (2008), and recommendations made.peer-reviewe
Maternal awareness of health promotion, parental and preschool childhood obesity
Aim: To investigate the association between parental and preschool childhood obesity, as well as maternal awareness of public health promotion on healthy eating with parental and preschool childhood obesity.
Methods: Data were collected by measuring the height and weight of two hundred randomly selected three-year old children and their parents. Details of the early feeding and dietary styles and level of health promotion awareness were assessed in faceto-face structured health interviews with the parents.
Results: There were statistically significant relationships between childhood obesity and parents’ obesity (r=0.2; p<0.001). A higher proportion of overweight and obese preschool children showed that their mothers lacked awareness of health promotion as compared to children with normally accepted weight (χ2 (6, n=200)=17.32, p=0.008). Maternal awareness of health promotion on healthy eating appeared to have a protective effect against overweight/obesity in three year old children (odds ratio=0.38, 95% CI=0.20 to 0.70). Furthermore, a higher proportion of overweight/obesity mothers had no awareness of health promotion as compared to mothers with normally accepted weight (χ 2 (4, n=200)=13.29, p=0.01). Maternal awareness of health promotion appeared to also have a protective effect against overweight/obesity in mothers (odds ratio=0.51, 95% CI=0.28 to 0.95).
Conclusions: This study showed the protective effect of maternal awareness of health promotion on maternal and preschool childhood obesity. Additionally, this study showed that overweight and obese preschool children had parents who were also overweight and obese.peer-reviewe
Existence and Nash Implementation of Efficient Sharing Rules for a Commonly Owned Technology
Suppose that a group of individuals owns collectively a technology which produces a consumption good by means of a (possibly heterogeneous) input. A sharing rule associates input contributions with a vector of consumptions that are technologically feasible. We show that the set of allocations obtained by any continuous sharing rule contains a subselection that is Pareto efficient. We also present a mechanism that implements in Nash equilibrium the Pareto efficient allocations contained in an arbitrary sharing rule
From Buses to BRT: Case Studies of Incremental BRT Projects in North America, MTI Report 09-13
Bus Rapid Transit (BRT) uses different combinations of techniques to improve service, such as bus-only lanes and roads, pre-boarding fare collection, transit priority at traffic signals, stylish vehicles with extra doors, bus stops that are more like light rail stations, and high frequency service. This study examines five approaches to BRT systems as implemented by public transit agencies in California, Oregon, and Ontario. The case studies as a group show that BRT can be thought of as a discretionary combination of elements that can be assembled in many different combinations over time. Every element incrementally adds to the quality or attractiveness of the service. This latitude provides transit agencies with many benefits, including the ability to match infrastructure with operating requirements. For example, a BRT service can combine operations serving free flowing arterial roads in the fringes of the downtown with dedicated lanes in areas closer to city center where congestion is greatest. Buses can operate both on and off the guide way, extending the corridors in which passengers are offered a one-seat ride with no transfer required. Transit agencies also can select specific BRT components and strategies, such as traffic signal priority and increased stop spacing, and apply them to existing local bus operations as a way to increase bus speeds and reduce operating costs. The specific elements selected for a BRT route can be implemented all at once, or in incremental stages either or both geographical extensions or additions of features. All of the case studies showed ridership improvements, but the Los Angeles Metro Rapid bus system illustrates the wide geographic coverage, improved ridership, and moderate cost per new rider that is possible with an approach that includes fewer BRT features spread over more miles of route. Quantitative results from the case studies suggest that incremental improvements, applied widely to regional bus networks, may be able to achieve significant benefits at a lower cost than substantial infrastructure investments focused upon just one or a few corridors
Returns to Mobility in the Transition to a Market Economy
In spite of ongoing dramatic changes in labor market structure, transitional economies display rather low worker flows across sectors and occupations. Such low mobility can be explained by low returns to job changes as well as by market segmentation in the allocation of job offers. We develop an econometric model which enables us to characterize intertemporal changes in probabilities of dismissal, remuneration, and offer arrival rates on the basis of information on observed transitions and wage payments. The model is estimated using data from the Polish Labor Force Survey. Our results indicate a significant degree of segmentation in the allocation of job offers and more stability in public sector versus private sector jobs. Our model can also be used for policy experiments. In particular, we infer that reductions of 10 per cent in the generosity of unemployment benefits will not significantly boost outflows from the unemployment state. These findings support explanations for low mobility in transitional economies, which are based on informational failures, and high costs of moving from public to private enterprises for those with high levels of job tenure and labor market experience in the public sector.http://deepblue.lib.umich.edu/bitstream/2027.42/39604/2/wp217.pd
The Finnish Development Cooperation in the Water Sector
This report evaluates Finland's participation in the water and sanitation sector from 1995 through 2009. Drawing from previous assessments as well as original research, the authors evaluate the country's performance in the water sector of its partner countries Ethiopia, Kenya, Nepal and Vietnam through an evaluation matrix. Most of the projects in these countries are water and sanitation for rural and small towns, though a few more recent projects in Ethiopia and Nepal focus on water resource management. The evaluation urges the Ministry of Foreign Affairs of Finland (MFA) to better globally disseminate information on a few of its projects that they consider to be "jewels in the crown", particularly Community Development Funds in Ethiopia and Rural Water Supply and Sanitation (Support) Programme in Nepal. Scaling up and replication present important challenges
