Finite state Markov processes and their aggregated Markov processes have been extensively studied, especially in ion channel modeling and reliability modeling. In reliability field, the asymptotic behaviors of repairable systems modeled by both processes have been paid much attention to. For a Markov process, it is well-known that limiting measures such as availability and transition probability do not depend on the initial state of the process. However, for an aggregated Markov process, it is difficult to directly know whether this conclusion holds true or not from the limiting measure formulas expressed by the Laplace transforms. In this paper, four limiting measures expressed by Laplace transforms are proved to be independent of the initial state through Tauber’s theorem. The proof is presented under the assumption that the rank of transition rate matrix is one less than the dimension of state space for the Markov process, which includes the case that all states communicate with each other. Some numerical examples and discussions based on these are presented to illustrate the results directly and to show future related research topics. Finally, the conclusion of the paper is given.
We explore people’s preferences for numbers in large proprietary data sets from two different lottery games. We find that choice is far from uniform, and exhibits some familiar and some new tendencies and biases. Players favor personally meaningful and situationally available numbers, and are attracted towards numbers in the center of the choice form. Frequent players avoid winning numbers from recent draws, whereas infrequent players chase these. Combinations of numbers are formed with an eye for aesthetics, and players tend to spread their numbers relatively evenly across the possible range.
Previous research on the role of recognition in decision-making in inferentialchoice has focussed on the Recognition Heuristic (RH), which proposes that insituations where recognition is predictive of a decision criterion, recognizedobjects will be chosen over unrecognized ones, regardless of any other availablerelevant information. In the current study we examine the role of recognition inpreferential choice, in which subjects had to choose one of a pair of consumerobjects that were presented with quality ratings (positive, neutral, andnegative). The results showed that subjects’ choices were largely basedon recognition, as the famous brand was preferred even when additional starratings rendered it as less attractive. However, the additional information didaffect the proportion of chosen famous items, in particular in the cases whenstar ratings for the recognised brand were negative. This condition alsoresulted in longer response times compared to neutral and positive conditions.Thus, the current data do not point to a simple compensatory mechanism inpreferential choice: although choice is affected by additional information, itseems that recognition is employed as an initial important first step in thedecision-making process.
This paper extends previous research showing that experienced difficulty ofrecall can influence evaluative judgments (e.g., Winkielman & Schwarz,2001) to a field study of university students rating a course. Studentscompleted a mid-course evaluation form in which they were asked to list either 2ways in which the course could be improved (a relatively easy task) or 10 waysin which the course could be improved (a relatively difficult task). Respondentswho had been asked for 10 critical comments subsequently rated the course morefavorably than respondents who had been asked for 2 critical comments. Aninternal analysis suggests that the number of critiques solicited provides aframe against which accessibility of instances is evaluated. The paper concludeswith a discussion of implications of the present results and possible directionsfor future research.
Increasing the availability of lower energy food options is a promising public health approach. However, it is unclear the extent to which availability interventions may result in consumers later ‘compensating’ for reductions in energy intake caused by selecting lower energy food options and to what extent these effects may differ based on socio-economic position (SEP). Our objective was to examine the impact of increasing availability of lower energy meal options on immediate meal energy intake and subsequent energy intake in participants of higher v. lower SEP. In a within-subjects design, seventy-seven UK adults ordered meals from a supermarket ready meal menu with standard (30 %) and increased (70 %) availability of lower energy options. The meals were delivered to be consumed at home, with meal intake measured using the Digital Photography of Foods Method. Post-meal compensation was measured using food diaries to determine self-reported energy intake after the meal and the next day. Participants consumed significantly less energy (196 kcal (820 kJ), 95 % CI 138, 252) from the menu with increased availability of lower energy options v. the standard availability menu (P < 0·001). There was no statistically significant evidence that this reduction in energy intake was substantially compensated for (33 % compensated, P = 0·57). The effects of increasing availability of lower energy food items were similar in participants from lower and higher SEP. Increasing the availability of lower energy food options is likely to be an effective and equitable approach to reducing energy intake which may contribute to improving diet and population health.
This chapter describes how to continue to develop as a leader. Great leadership is not something you ever really attain, but something you are constantly striving toward. Innovation and creativity help nurture your leadership potential; resting on your laurels leads to complacency and stale leadership. As with all things, this does not come without some work and introspection. Introspection is the work, and most leaders fail to develop because they’re unwilling or unable to take the extra steps to examine themselves and their group deeply, find out what’s working and what’s not, and come up with fixes. We discuss the importance of getting evaluations and feedback on your performance as a leader, and how to incorporate that feedback in a healthy manner. We discuss the importance of availability and accessibility. We talk about the importance of leading by example, “walking the walk.” We go into the importance of clear, concise, and honest messaging, as well as embracing change and learning from your mistakes. We reemphasize the importance of diversity and conclude with some core principles and values.
In most societies, many groups and individuals rely on places beyond the scope of the household to live and enjoy their rights, including their rights to water and sanitation. These groups include persons in penal institutions and detention centres, health care professionals and patients who spend long periods in hospitals and health centres, students in boarding schools and workers who are required to spend considerable lengths of time in open workplaces. They also include people who reside in those spheres because of homelessness, people living in poverty who may lack access to water and sanitation in or near their homes and people who work formally or informally in the public spaces of urban areas. More broadly, they include the general public who commute daily.
The debate around the international framework for HRtWS is permeated by challenges and endorsements from United Nations member states and civil society. Such a debate has implications both as to what precisely the content of the rights are and what the nature of countries’ obligations related to such rights is, as well as how these should be concretely realized in practical terms.
To provide a cross-country analysis of selection, availability, prices and affordability of essential medicines for mental health conditions, aiming to identify areas for improvement.
Methods
We used the World Health Organization (WHO) online repository of national essential medicines lists (EMLs) to extract information on the inclusion of essential psychotropic medicines within each country's EML. Data on psychotropic medicine availability, price and affordability were obtained from the Health Action International global database. Additional information on country availability, prices and affordability of essential medicines for mental disorders was identified by searching, up to January 2021, PubMed/Medline, CINAHIL, Scopus and the WHO Regional Databases. We summarised and compared the indicators across lowest-price generic and originator brand medicines in the public and private sectors, and by country income groups.
Results
A total of 112 national EMLs were analysed, and data on psychotropic medicine availability, price and affordability were obtained from 87 surveys. While some WHO essential psychotropic medicines, such as chlorpromazine, haloperidol, amitriptyline, carbamazepine and diazepam, were selected by most national lists, irrespective of the country income level, other essential medicines, such as risperidone or clozapine, were included by most national lists in high-income countries, but only by a minority of lists in low-income countries. Up to 40% of low-income countries did not include medicines that have been in the WHO list for decades, such as long-acting fluphenazine, lithium carbonate and clomipramine. The availability of generic and originator psychotropic medicines in the public sector was below 50% for all medicines, with low-income countries showing rates lower than the overall average. Analysis of price data revealed that procurement prices were lower than patient prices in the public sector, and medicines in the private sector were associated with the highest prices. In low-income countries, the average patient price for amitriptyline and fluoxetine was three times the international unit reference price, while the average patient price for diazepam was ten times the international unit reference price. Affordability was higher in the public than the private sector, and in high-income than low-income countries.
Conclusion
Access to medicines for mental health conditions is an ongoing challenge for health systems worldwide, and no countries can claim to be fully aligned with the general principle of providing full access to essential psychotropic medicines. Low availability and high costs are major barriers to the use of and adherence to essential psychotropic medicines, particularly in low-and middle-income countries.
This chapter discusses prospect theory at length, as a prime example of the ways fairly trivial changes in the presentation of a set of facts can dramatically alter public opinion. The chapter begins with an ancient idea, at least as old as Aristotle’s philosophy, that in a public debate over an issue, features quite peripheral to the facts of a case could be invoked, challenged, or described in order to maximize an argument’s persuasive power. The central idea behind the art of political rhetoric is what we call framing. The conviction that framing is a powerful persuasive tool for political elites in both democratic and non-democratic regimes is widely held and, in many ways, contradicts rational choice models of decision-making. Because frames do not change the underlying dimensions of a choice – the facts of the case – they should not affect our decisions, at least not according to a rational choice framework. Still, they often do.
A sense of security is important in palliative home care. Yet, knowledge about which components contribute most to feeling secure from the patients’ and family caregivers’ perspectives, especially since the introduction of specialist palliative home care, is sparse. The goal of the current study was to determine the key components contributing to a sense of security and how they relate to each other as experienced by patients and family caregivers in specialist and generalist palliative home care.
Methods
The current sub-study, as part of a larger study, was performed in different regions in Germany. Palliative care patients and family caregivers of at least 18 years of age, being cared for at home were interviewed using semi-structured interview guides following a three-factor model and analyzed by using a combined quantitative-qualitative-content approach.
Results
One hundred and ninty-seven patients and 10 carers completed interviews between December 2017 and April 2019. The majority of patients were diagnosed with an oncological disease. Sense of security was mentioned particularly often suggesting its high relevance. We identified nine subcategories that were all mentioned more frequently by specialist than generalist palliative home care recipients in the following order of priority and relation: (i) patient-centeredness: availability, provision of information/education, professional competence, patient empowerment, and trust (ii) organizational work: comprehensive responsibility, external collaboration, and internal cooperation, and (iii) direct communication.
Significance of results
The work of specialist palliative home care services in particular was perceived as very effective and beneficial. Our findings confirm a previously developed three-factor model allowing for generalizability and revealed that availability was most important for improving the sense of security for effective palliative home care.
In view of many problems associated with the availability of global navigation satellite system (GNSS) signals in high-altitude space, this paper presents a comprehensive and systematic analysis. First, the coverage and strength characteristics of GNSS signals in high-altitude space (i.e., space above the GNSS constellation) are presented, and the visibility of GNSS signals is evaluated by combining these two factors. Second, the geometric configuration and geometric dilution of precision (GDOP) of visible GNSS satellites are analysed. Then, the Doppler shift range of the GNSS signals is deduced based on the dynamic performance of high-altitude spacecraft. Finally, taking GaoFen-4 (GF-4) as the application object, the availability of GNSS signals is simulated and evaluated. GNSS signals in high-altitude space are generally weak, and the visible GNSS satellites are concentrated in the high-elevation range. The combination of main and side lobe signals and compatibility of multiple constellations can increase the number of visible satellites, improve the geometry configuration, reduce GDOP, and thus improve the availability of GNSS signals. The results of this research can provide technical support for the design and development of GNSS receivers suitable for high-altitude space.
Critical thinking in science and many other disciplines should encompass creative, analytical, practical, and wise thinking. Underlying it are both cognitive processes and dispositions–that is, what a person can do and what a person chooses to do. Critical thinking is both domain-general and domain-specific. The domain-specific elements of it cannot be well captured by general tests of critical thinking. We have found that critical thinking in STEM disciplines involves skills that are quite different from those involved in taking tests of cognitive and academic skills. Some of these skills are generating hypotheses, generating experiments, and drawing conclusions. In our tests of these skills, which we have administered to students at Cornell University, scores on the tests correlated not at all or even negatively with tests of academic preparation, such as the SAT and the ACT. Thus, universities that select future scientists and engineers on the basis of such standardized tests may be choosing the wrong people unless they can assure that those people are good scientific reasoners, not just good takers of analytically-oriented tests.
Behavioral paternalists often distinguish their views from harder forms of paternalism by emphasizing the moderate character of their proposals. Insights from the academic literature on slippery slopes suggest that behavioral paternalist policies are particularly vulnerable to expansion, which makes the claim to moderation unsustainable. This is true even if policymakers are rational (in the neoclassical sense), but the slippery-slope threat is even greater if policymakers share the behavioral and cognitive biases attributed to the people their policies are supposed to help. Rational slope mechanisms include altered incentive slopes, authority and simplification slopes, and expanding justification slopes. Behavioral slope mechanisms include action bias, overconfidence, confirmation bias, present bias, availability and salience effects, framing and extremeness aversion, and affect and prototype heuristics. The theoretical and empirical vagueness of behavioral paternalism creates gradients that encourage the gradual expansion of policies. Finally, the particular way in which leading behavioral paternalists have framed the issue of paternalism gives rise to an inherently expansionist dynamic, which we call the paternalism-generating framework.
Rational beliefs need not be truth-tracking nor adhere strictly to basic logical or statistical-inference principles. They must simply be appropriate to the attainment of the individual’s purposes in specific contexts. We analyze various “errors” that behavioral economists have supposedly discovered in belief formation. Specifically, we examine supposed errors related to imperfect logical deduction, the conjunction fallacy (including the famous “Linda problem”), availability bias, overconfidence bias, and distorted salience. In each case we show that the standard behavioral analysis is too simple and that many of their behaviors qualify as inclusively rational. The fundamental error of behavioral analysts is to expect that universal, abstract methods of belief formation will be appropriate for guiding all concrete choices.
Real-world policymakers face pressure to take action, to legislate, and to attempt to solve problems even in imperfect ways. What kind of paternalistic policies can we reasonably expect policymakers to create? We argue that public-choice pressures will tend to produce suboptimal paternalistic policies, even if we assume behavioral paternalists’ conclusions about human behavior are generally correct. Rational ignorance, bureaucratic self-interest, concentrated benefits and diffuse costs, the influence of rent-seekers and moralists, and other factors will tend to shape policy in undesirable ways. If policymakers are susceptible to biases such as those attributed to regular people, the results could be even worse. Biases with the potential to adversely affect policymaking include action bias, overconfidence, confirmation bias, availability and salience effects, affect and prototype heuristics, and present bias. Because the political sphere offers weak incentives for the self-correction of biases, we expect such biases to be more significant in the public than in the private sphere.
Signal-in-space (SIS) continuity and availability are important indicators of performance assessment for Global Navigation Satellite Systems (GNSSs). The BeiDou Navigation Satellite System (BDS) Open Service Performance Standard (BDS-OS-PS-1.0) has been released, and the corresponding public performance indicators have been provided, but the actual SIS performance is uncertain to users. SIS continuity and availability are primarily related to unscheduled outages (failures). Therefore, based on the existing failure classification system and actual operation modes, four types of failure modes are first analysed: long-term failure related to satellite service period, maintenance failure related to satellite manoeuvring, short-term failure associated with random repairable anomalies and equivalent failure corresponding to a combination of the above three types of failures. Second, based on the failure classification and selected precise and broadcast ephemerides from 2015–2016, the Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) of each failure type are obtained using appropriate detection methods. Finally, using a corresponding assessment model, the SIS continuity and availability of BeiDou are calculated for individual and equivalent failure cases, and these are compared with the provided index in the BDS Open Service Performance Standard.
ART was pioneered in Africa in the 1980’s. Subsequently, ART centres emerged around the continent, mostly by specialists acquiring skills abroad. Despite this, ART activity remains scant in most African countries and absent in several others.
Historically, ART surveillance in Africa has been similarly scant and fragmented. Recently however, the African Network and Registry for ART (ANARA) has been established with the vision to reduce the high burden of infertility in Africa through ART; and its mission to bring together ART centres within and across countries and to collect data pertaining to availability, utilization, effectiveness and safety of ART. First registry data, collected from 40 centres in 13 countries, and will be published shortly. ANARA protects the anonymity of centres and patients and the ownership of data.
The successful establishment of ANARA is rooted in a collaborative spirit of engagement with ART centres and other stakeholders, developmental assistance from both the Latin American and World Registry, and the importance of data in reducing the burden of infertility in Africa.
Asia is composed of more than 40 countries where about 60% of the global population live. Since Asia is the largest and geographically variable continent, where cultural and social backgrounds are very diverse in every part of this area, it is almost impossible to describe the whole area in one chapter. Rapid decline of birth rates in multiple countries, particularly in eastern Asia, drew wide public attention and promoted the treatment and care for infertile couples. Particularly, assisted reproductive technology (ART) has significantly spread in many Asian countries and its growth is still ongoing. Although ART registries were established in several Asian countries many years ago, there is no Asian regional registry because of this diverse situation of this area.
Since 1999 surveillance of ART in Europe is carried out by the European IVF-monitoring (EIM) Consortium, founded in June 1999 by the European Society of Human Reproduction and Embryology (ESHRE). EIM is organized by the representatives of national registries of European countries offering ART. The high diversity of participating European countries pose a serious challenge for obtaining complete data and interpreting the results. Notwithstanding this challenge EIM has managed in 2014 to collect the data of 38 from 42 participating European countries (90.5%) and 1280 institutions (90.2% of all known in Europe). Annual meetings supported by ESHRE have created a spirit of mutual understanding and have contributed much to increase the level of participation. Every year, EIM published an annual report with cross-sectional data, typically made of more than 700'000 treatment cycles of ART. The first data set of 1997 was published in 2001 and was followed by 17 reports in the journal „Human Reproduction“.
To (i) describe the proportion of foods and beverages available on school canteen menus classified as having high (‘green’), moderate (‘amber’) or low (‘red’) nutritional value; (ii) describe the proportion of these items purchased by students; and (iii) examine the association between food and beverage availability on school canteen menus and food and beverage purchasing by students.
Design
A cross-sectional study was conducted as part of a larger randomised controlled trial (RCT).
Setting
A nested sample of fifty randomly selected government schools from the Hunter New England region of New South Wales, Australia, who had participated in an RCT of an intervention to improve the availability of healthy foods sold from school canteens, was approached to participate.
Subjects
School principals, canteen managers and students.
Results
The average proportion of green, amber and red items available on menus was 47·9, 47·4 and 4·7 %, respectively. The average proportion of green, amber and red items purchased by students was 30·1, 61·8 and 8·1 %, respectively. There was a significant positive relationship between the availability and purchasing of green (R2=0·66), amber (R2=0·57) and red menu items (R2=0·61). In each case, a 1 % increase in the availability of items in these categories was associated with a 1·21, 1·35 and 1·67 % increase in purchasing of items of high, moderate and low nutritional value, respectively.
Conclusions
The findings provide support for school-based policies to improve the relative availability of healthy foods for sale in these settings.
