The convolutional neural network for Pacific decadal oscillation forecast
The Pacific decadal oscillation (PDO) is often described as a long-lived El Niño-like pattern of Pacific climate variability, and it has widespread climate and ecosystem impacts. PDO forecasts can provide useful information for policymakers on how to handle PDO impacts. Nevertheless, due to the long duration of the PDO cycles and their complex formation mechanisms, it remains a challenge to predict long lead time PDO. In this paper, we propose a …
The safety and effectiveness comparison of Delta Medical's Peek interface screw and Endobutton and that of Smith & Nephew's in arthroscopic anterior cruciate ligament reconstruction: A multicenter pro…
Background To reduce the costs and financial burden in the ACLR treatment, we compare the early clinical outcomes and Magnetic Resonance Imaging (MRI) results of Delta Medical's PEEK (polyether ether ketone) interference screw and EndoButton with those of Smith & Nephew's PEEK interference screw and EndoButton in patients with arthroscopic anterior cruciate ligament reconstruction. Methods A total of 104 patients in five different medical centers…

On Inequality‐Sensitive and Additive Achievement Measures Based on Ordinal Data
This paper, following earlier work on the measurement of inequality when only ordinal information is available, proposes an axiomatic derivation of a new class of inequality‐sensitive and additive achievement measures. Use is then made of these indices to study health achievement in Europe, using information on self‐assessed health in 30 countries, based on the European Health Interview Survey (wave 2)
Rawlsian versus Utilitarian: Teachers' Incentives and the Distribution of Student Performance
By using the test score of the least able student in a classroom as the objective function (Rawlsian optimum), this paper examines the implications for teachers' incentives and compares them with the objective that uses the average test scoreof all the students in a classroom (utilitarian optimum). We show that for certain human-capital production functions and teachers' effort cost functions, the Rawlsian optimum yields at least the same average…

CHAPTER 14 Consequentialism and Non‐Consequentialism: The Axiomatic Approach
Most, if not all, practitioners of welfare economics and social choice theory are presumed to be welfaristic in their conviction. Indeed, they evaluate the goodness of an economic policy and/or economic system in terms of the welfare that people receive at the culmination outcomes thereby generated. Recent years have witnessed a substantial upsurge of interest in the non‐welfaristic bases, or even the non‐consequentialist bases, of welfare econom…

Norm-Constrained Choices
This paper develops a general and unified framework to discuss individual choice behaviors that are constrained by the individual’s internalized norms. We propose a new notion of rationalizablity of a choice function that incorporates such constraints, and axiomatically study several norm-constrained choice behaviors
On Measuring Personal Connections and the Extent of Social Networks
The notions of personal connection and social networks are key ingredients of the increasingly important concept of social capital in social sciences in general and in economics in particular. This paper discusses the problem of measuring personal connection and the extent of social networks that may exist in a society. For this purpose we develop several conceptual and analytical frameworks. In the process, we axiomatically characterize several …

Capability Sets as the Basis of a New Measure of Human Development
Human development is about much more than growth in real income. It is about expanding the choices human beings have to lead lives that they value. The potential choices and their expansion can be captured by capability sets that consist of various functioning vectors. The standard of living is then reflected in these capability sets. This paper proposes a particular way of measuring the standard of living available either to an individual or hou…

Similarity of Options and the Measurement of Diversity
This article analyzes the measurement of the diversity of sets based on the dissimilarity of the objects contained in the set. We discuss axiomatic approaches to diversity measurement and examine the considerations underlying the application of specific measures. Our focus is on descriptive issues: rather than assuming a specific ethical position or restricting attention to properties that are appealing in specific applications, we address the fo…

On Measuring Deprivation and the Standard of Living in a Multidimensional Framework on the Basis of Aggregate Data
In measuring social deprivation in a multidimensional framework, ideally one should first measure each individual's overall deprivation, and then aggregate the overall deprivation levels of all individuals. However, given only aggregate data, one is often forced to measure social deprivation in terms of each attribute separately and then to aggregate them so as to get the overall social deprivation. This paper shows that it is only under extremel…

Rationality and External Reference
This article is about rationality conditions underlying individual choice and questions the universal applicability of the `standard conditions'. It is argued that when making choices and decisions, an individual appeals to external references. As a consequence, the issue of rationality can be sensibly analyzed only if external references are spelled out. Utility maximization, menus, private and social norms are some of the examples of external r…

On Ranking Opportunity Sets in Terms of Freedom of Choice
The paper explores the notion of freedom of choice which is of considerable importance in welfare economics and the theory of social choice. Three plausible axioms are introduced for ranking alternative opportunity sets in terms of the degrees of freedom that they offer to the agent making choices. It is shown that, under these axioms, judgements about degrees of freedom of choice have to be based on the naive principle of simply counting the num…
