This lecture gives a brief overview of an evolutionary theory of fairness. Most of the ideas discussed in the lecture can be found in the book Natural Justice. The lecture begins by determining how and why the norms of fairness evolved, and examines the device of the original position. This device is the stylised form of the common structure underlying all fairness norms. The lecture then looks at the possibility of having justice as fairness, pure foraging societies, and the basics of game theory. Coordination games, reciprocity, the folk theorem, selecting equilibria, and the deep structure of fairness are some of the concepts discussed in detail in this lecture.

Abstract We investigated the mechanism of the Jaffé reaction for determination of creatinine by studying the spectrophotometric, kinetic, and equilibrium properties of the reaction of picrate with creatinine and with cyclic and aliphatic ketones. Absorbance spectra for the reaction products of picrate with all the ketones were superimposable with that of creatinine (Amax, 490 nm). Cyclic ketones not containing nitrogen had a molar absorptivity less than half that of creatinine and equilibrium constants approximately 0.01 that of creatinine. Aliphatic ketones, except for benzylacetone, had molar absorptivities similar to that of creatinine, but all of these compounds had equilibrium constants approximately a tenth or less that of creatinine. The common structure for all of the compounds reacting with picrate is the carbonyl group. The variable magnitude of interference for aliphatic and cyclic ketones is ascribable to the different rate constants, molar absorptivities, and equilibrium constants as compared with creatinine. Structures adjacent to the carbonyl group significantly affect the absorptivity and equilibrium constant, but steric hindrance is the major factor affecting the rate of reaction. We postulate that the carbonyl group is required for the Jaffé reaction, and we suggest a mechanism for the reaction.

To generate a group-specific monoclonal antibody (McAb) against danofloxacin (DANO), enrofloxacin (ENR) and ciprofloxacin (CIP), glutaraldehyde was used to link the presentative hapten of CIP to the immunogen and coating antigen, respectively, leaving the common structure of these 3 drugs exposed in both conjugates as a major antigenic site. Consequently, a McAb (6D3) with high cross-reactivity to this three antibiotics has been obtained by using hybridomas technique. In a biotin-avidin mediated enzyme-linked immunosorbent assay, the IC50values for DANO, ENR and CIP were 5.1, 4.5 and 4.2 ng mL-1, respectively. The ELISA was used for the detection of spiked DANO and ENR+CIP in milk. The recoveries ranged from 74.1 to 92.4% and coefficients of variation were in a range of 6.6-11.9%. The accuracies and sensitivity of the method were good for simultaneous analysis of the 3 drugs in milk after a simple sample extraction process.

The seasonal organization patterns of demersal assemblages (fish and cephalopods) in the Gulf of Lions were investigated on the basis of a set of bottom trawl surveys. The use of Partial Triadic Analysis (PTA) provided a detailed representation of: (1) the common part of the spatial organization of demersal assemblages at seasonal scale; and (2) the seasonal variability of each species around this common structure. During the course of the study, demersal assemblages exhibited a strong seasonal stability in their organization patterns and only few species showed a strong seasonal variation in their spatial distribution. Demersal assemblages of the Gulf of Lions were structured primarily on the basis of a non depth coast–open sea gradient, which occurred from the coast to the midshelf region. The influence of depth on the structure of fish assemblages appeared to be only of limited importance and mainly restricted to the continental slope area. The PTA combined with contouring technics could be used to improve our knowledge of community structuring factors, and offers a theoretical framework to assess the reproducibility of multispecies structures.

Synthesizing face sketches with both common and specific information from photos has been recently attracting considerable attentions in digital entertainment. However, the existing approaches either make the strict similarity assumption on face sketches and photos, leading to lose some identity-specific information, or learn the direct mapping relationship from face photos to sketches by the simple neural network, resulting in the lack of some common information. In this paper, we propose a novel face sketch synthesis based on the Markov random neural fields including two structures. In the first structure, we utilize the neural network to learn the non-linear photo-sketch relationship and obtain the identity-specific information of the test photo, such as glasses, hairpins and hairstyles. In the second structure, we choose the nearest neighbors of the test photo patch and the sketch pixel synthesized in the first structure from the training data which ensure the common information of Miss or Mr Average. Experimental results on the Chinese University of Hong Kong face sketch database illustrate that our proposed framework can preserve the common structure and capture the characteristic features. Compared with the state-of-the-art methods, our method achieves better results in terms of both quantitative and qualitative experimental evaluations.

Happiness, life and liberty are central terms in the history of philosophy. At the same time, they belong to the core of Christianity. We find these key terms already in the New Testament and we also find that reflections on these terms have defined their meanings in new ways throughout the centuries. I show the way how the original meanings have gradually changed. In contemporary reflections, we find interesting attempts to reform the traditional meanings, in which the influence of the natural sciences and twentieth century philosophies (such as phenomenology, existentialism, Marxism and post-modernism) have proven to be decisive. Christianity-oriented philosophies in contemporary academia, such as those of Michel Henry or Jean-Luc Marion, offer versions of these thoughts. The main defect of the traditional understandings may be seen simply their isolationist approach, that is to say, their approach to consider these terms as unrelated to one another. My own solution finds the common structure in the reality of revelation and considers life, liberty, and happiness as moments only insufficiently grasped by traditional approaches.

Proponents of public reason views hold that the exercise of political power ought to be acceptable to all reasonable citizens. This article elucidates the common structure shared by all public reason views, first by identifying a set of questions that all such views must answer and, second, by showing that the answers to these questions stand in a particular relationship to each other. In particular, we show that what we call the ‘rationale question’ is fundamental. This fact, and the common structure more generally, are often overlooked or distorted within the literature. As a result, we argue, several prominent argumentative moves made by both critics and defenders of public reason are unsuccessful. Our overall conclusion is that discussions of public reason views would be more fruitful if they made consistent use of the common structure we identify.

This study looks into the common strategic moves of Chinese firms to create appeal for their products in emerging markets. The focus is on the common competitive factors that make them to have high rate of success and prosperity compared to first movers firms from advanced markets in developing countries marketplace. Past studies showed that a firm without established brands, technology knowhow and management capabilities are likely to face with survival and performance problems, and may also reduce the firm's strategic options and growth opportunities in developing economies. Chinese firms are known to lack established brands and important core capabilities but have been able to demonstrate a unique trend in emerging countries market place. They have a common structure and trend in the ways Chinese firms create appeal to users and potential buyers in emerging market environment. This present research explored the situation with case research interview of seven Chinese firms in Nigeria.
