The Fair Division of Hereditary Set Systems

We consider the fair division of indivisible items using the maximin shares measure. Recent work on the topic has focused on extending results beyond the class of additive valuation functions. In this spirit, we study the case where the items form an hereditary set system. We present a simple algorithm that allocates each agent a bundle of items whose value is at least $0.3667$ times the maximin share of the agent. This improves upon the current best known guarantee of $0.2$ due to Ghodsi et al. The analysis of the algorithm is almost tight; we present an instance where the algorithm provides a guarantee of at most $0.3738$. We also show that the algorithm can be implemented in polynomial time given a valuation oracle for each agent.Comment: 22 pages, 1 figure, full version of WINE 2018 submissio

Presume It Not: True Causes in the Search for the Basis of Heredity

Kyle Stanford has recently given substance to the problem of unconceived alternatives, which challenges the reliability of inference to the best explanation (IBE) in remote domains of nature. Conjoined with the view that IBE is the central inferential tool at our disposal in investigating these domains, the problem of unconceived alternatives leads to scientific anti-realism. We argue that, at least within the biological community, scientists are now and have long been aware of the dangers of IBE. We re-analyze the nineteenth-century study of inheritance and development (Stanford’s case study) and extend it into the twentieth century, focusing in particular on both classical Mendelian genetics and the studies by Avery et al. on the chemical nature of the hereditary substance. Our extended case studies show the preference of the biological community for a different methodological standard: the vera causa ideal, which requires that purported causes be shown on non-explanatory grounds to exist and be competent to produce their effects. On this basis, we defend a prospective realism about the biological sciences

Family names as indicators of Britain’s changing regional geography

In recent years the geography of surnames has become increasingly researched in genetics, epidemiology, linguistics and geography. Surnames provide a useful data source for the analysis of population structure, migrations, genetic relationships and levels of cultural diffusion and interaction between communities. The Worldnames database (www.publicprofiler.org/worldnames) of 300 million people from 26 countries georeferenced in many cases to the equivalent of UK Postcode level provides a rich source of surname data. This work has focused on the UK component of this dataset, that is the 2001 Enhanced Electoral Role, georeferenced to Output Area level. Exploratory analysis of the distribution of surnames across the UK shows that clear regions exist, such as Cornwall, Central Wales and Scotland, in agreement with anecdotal evidence. This study is concerned with applying a wide range of methods to the UK dataset to test their sensitivity and consistency to surname regions. Methods used thus far are hierarchical and non-hierarchical clustering, barrier algorithms, such as the Monmonier Algorithm, and Multidimensional Scaling. These, to varying degrees, have highlighted the regionality of UK surnames and provide strong foundations to future work and refinement in the UK context. Establishing a firm methodology has enabled comparisons to be made with data from the Great British 1881 census, developing insights into population movements from within and outside Great Britain

Building Sustainable Partnerships to Promote Women's Political Representation in Southeast Asian Region

In a democratic country, gender equality is an element that needs to be guaranteed by the government, particularly in political positions such as in government offices, political parties, and other decision-making institutions. Unfortunately, such condition faces a significant obstacle that comes in the form of patriarchy system in the society, especially in the parliament as an institution representing the society. Currently, there is already an internationally recognized minimum target of 30% women as political representatives in the legislature bodies, as part of the initiative to promote women representation in the parliament. It is expected that with this target, women would have a starting point to claim their rights and to have a significant influence in the decision-making process

Marsilius of Padova as a Democratic Theorist

In this essay I focus on the form of government defended by Marsilius of Padua in the first Discourse of Defensor pacis (1324). The interpretation of his overall account depends heavily on our understanding of the “major and valentior part” of the citizenry upon which all legislative and elective powers are bestowed. I argue that there is sufficient textual evidence to believe that the above term refers not to some small elite group but to the totality of citizens or the overwhelming majority of them. I also argue that his imaginary polity meets all the necessary conditions that any political regime should meet in order for it to be characterised as an essentially democratic one. Thus, Marsilius deserves a more prominent position in the history of democratic ideas
