Profile Reduction

Researchers used graph-theory approaches to design the state-of-theart low-cost heuristics for profile reduction. This paper evolves and selects four low-cost heuristics for profile reduction using a genetic programming hyperheuristic approach. This paper evaluates the resulting heuristics for profile reduction from the genetic programming hyperheuristic approach in two application areas against the low-cost heuristics for solving the problem. The results obtained on a set of standard benchmark matrices taken from the SuiteSparse sparse matrix collection indicate that the resulting heuristics from the genetic programming hyperheuristic approach does not compare favorably with a high-quality heuristics for profile reduction.

In this commentary, we discuss the state of affairs concerning the clinical care of females with Turner syndrome (TS) in Germany. TS is a rare disease and new international guidelines describe an appropriate setup for optimal clinical care. Several countries have implemented a program with centralized adult Turner syndrome clinics, which are now found in France, Denmark, the Netherlands, Sweden, parts of England and possibly other countries, but hitherto not in Germany. Such an approach should ensure the availability of high quality multi-disciplinary care for all women with TS to be treated and to detect all the conditions that have been associated with TS, which typically appear at odd times during the lifetime of a female with TS. Care should be offered at no added cost for the patient, and treatment with relevant drugs should be available at reasonable cost for the individual patient. Currently, it is quite problematic that many female sex hormone preparations are not available at low cost in a number of countries. Additional problems include supply chain issue which lead to patients not being able to buy their usual drug for a certain period of time. We think it is timely that countries improve the care for individuals with rare conditions, such as TS.

The availability of low-cost and high-quality wearable cameras combined with the unlimited storage capacity of video-sharing websites have evoked a growing interest in First-Person Videos. Such videos are usually composed of long-running unedited streams captured by a device attached to the user body, which makes them tedious and visually unpleasant to watch. Consequently, it raises the need to provide quick access to the information therein. We propose a Sparse Coding based methodology to fast-forward First-Person Videos adaptively. Experimental evaluations show that the shorter version video resulting from the proposed method is more stable and retain more semantic information than the state-of-the-art.

The need of additional universities in Indian higher education system to provide higher education to all eligible population of the country and the success of private university model in the USA tempted the Indian government to give permission to establish Private Universities in the country. Accordingly, based on section 22 of UGC act, the Indian government has allowed the state governments to establish private universities in the respective states. Presently there are 264 private universities in the country spread over 22 states. Due to non-availability of any financial support from the state and central governments, private universities are trying to sustain through their only strategy of service differentiation through 21st century curriculum and industry integrated programme design. In this paper, we have studied and compared some of the private universities in India in terms of their infrastructure, faculties, variety of courses, and fee structure of identified courses. We have also studied the performance scores given by NIRF, MHRD, Govt. of India for various criterions like Teaching, Learning & Resources, Research and Professional Practice, Graduation Outcomes, Outreach and Inclusivity, Public Perception. Based on the annual fee charged by the private universities established before 2010, we have identified three types of strategies which include low-cost – low quality, high-fee – high-quality, and nominal-fee – high quality strategies and analysed them based on the philosophy and background of such universities in general. We have also identified other innovative strategies offered by many private universities, in general, to differentiate themselves from publicly funded universities. The paper also contains some recommendations based on the observations to improve the quality, relevancy, and effectiveness of educational services and research contributions of private universities.

Hospital Conversions

The pressures encountered by hospitals in the current era of reimbursement declines and stiffened competition are well known. As the “ultimate” payors—primarily employers and government—aggressively continue to seek low cost care, the response of the hospital industry has been to move toward consolidation and efficiency-enhancing mechanisms.Increasingly, nonprofit, tax-exempt hospitals have come to believe that they are at a significant disadvantage vis-á-vis their for-profit brethren in their ability to attract the capital needed to compete in the market. A growing trend among nonprofit hospitals, therefore, is to sell to or enter into a joint venture with a proprietary organization, or alternatively to convert to for-profit status. In 1995, fifty-eight nonprofit hospitals became for-profit; hospital conversions to for-profit status in 1996 are projected to outstrip the pace established the prior year.The conversion trend has not gone unnoticed at the state level. Recently, several states have proposed or enacted laws regulating sales and conversions of nonprofit hospitals, and many more states are contemplating such legislation.

The use of low air quality networks has been increasing in recent years to study urban pollution dynamics. Here we show the evaluation of the operational Aburrá Valley’s low-cost network against the official monitoring network. The results show that the PM2.5 low-cost measurements are very close to those observed by the official network. Additionally, the low-cost allows a higher spatial representation of the concentrations across the valley. We integrate low-cost observations with the chemical transport model Long Term Ozone Simulation-European Operational Smog (LOTOS-EUROS) using data assimilation. Two different configurations of the low-cost network were assimilated: using the whole low-cost network (255 sensors), and a high-quality selection using just the sensors with a correlation factor greater than 0.8 with respect to the official network (115 sensors). The official stations were also assimilated to compare the more dense low-cost network’s impact on the model performance. Both simulations assimilating the low-cost model outperform the model without assimilation and assimilating the official network. The capability to issue warnings for pollution events is also improved by assimilating the low-cost network with respect to the other simulations. Finally, the simulation using the high-quality configuration has lower error values than using the complete low-cost network, showing that it is essential to consider the quality and location and not just the total number of sensors. Our results suggest that with the current advance in low-cost sensors, it is possible to improve model performance with low-cost network data assimilation.

Constitutional Issue

Abstract In many countries, constitutional amendments require the direct approval of voters, but the consequences of fundamental changes to the powers and operations of the state are difficult to anticipate. The referendums literature suggests that citizens weigh their prior beliefs about the merits of proposals against the heuristic provided by the partisanship of the proposer, but the relative salience of these factors across constitutional issue areas remains underexplored. This paper examines the determinants of citizen preferences on 12 diverse constitutional issues, based on a novel survey experiment in Japan. We show that support for amendments is greater when its proposer is described as non-partisan. However, constitutional ideology moderates this effect. Those who prefer idealistic constitutions that elevate national traditions tend to value proposals that expand government powers, compared to those who prefer pragmatic constitutions that constrain government authority. These results highlight the significance of constitutional beliefs that are independent of partisanship.
