Link prediction attracts the attention of a large number of researchers due to the extensive application in social and economic fields. Many algorithms have been proposed in recent years. They show good performance because of having own particularly selected networks. However, on the other networks, they do not necessarily have good universality. Moreover, there are no other methods to evaluate the performance of new algorithm except AUC and precision. Therefore, we cannot help questioning this phenomenon. Can it really reflect the performance of an algorithm? Which attributes of a network have great influence on the prediction effect? In this paper, we analyze 21 real networks by multivariate statistical analysis. On the one hand, we find that the heterogeneity of network plays a significant role in the result of link prediction. On the other hand, the selection of network is very essential when verifying the performance of new algorithm. In addition, a nonlinear regression model is produced by analyzing the relationship between network properties and similarity methods. Furthermore, 16 similarity methods are analyzed by means of the AUC. The results show that it is of great significance for the performance of a new algorithm to design the evaluation mechanism of classification.

It is related leg problems to the realization of the necessity of doing a detailed analysis of the phenotype correlations between body weight and exterior measurements. As a result of the study, lower coefficients have been obtained of the correlation between the girth of the tarso metatarsus on one hand, and the body weight and the girth behind the wings, on the other hand (respectively 0.563 and 0.608), compared with the one between the body weight and the girth behind the wings (0.898). It is advisable in the selection of ostriches to take into consideration the necessity of a higher phenotypic correlation between the girth of the tarso metatarsus on the one hand, and the body weight and the girth behind the wings on the other hand, with a view to preventing leg problems.

This article focuses on the exegetical interpretation of Luke's narrative of the census (or registration) carried out at the time of Jesus's birth (Luke 2: 1–5). After some brief remarks on the juridical institution of the census (the so-calledprofessio census) in ancient Rome, a selection of the exegetical interpretations of this pericope developed by various ancient and medieval authors is presented. Origen, Ambrose, Orosius, Bede and Bonaventure are discussed, among others. A number of medieval authors, including Dante Alighieri and Bartolus of Saxoferrato, are also considered. The analysis argues, on the one hand, that a spiritualization of the institution of the census occurred and led to the spiritual empire of Christ being seen as replacing the temporal empire of Augustus; on the other, that reference to this institution was used to legitimize political authority in the eyes of believers. This interpretative tradition is thus shown to offer a vivid example of the close intertwining of theological and juridical concepts and practices which has characterized the relationship between the Church and empire from the former's very beginning.

The debates on, in, and between feminist and trans* movements have been politically intense at best and aggressively hostile at worst. The key contestations have revolved around three issues: First, the question of who constitutes a woman; second, what constitute feminist interests; and third, how trans* politics intersects with feminist politics. Despite decades of debates and scholarship, these impasses remain unbroken. In this article, our aim is to work out a way through these impasses. We argue that all three types of contestations are deeply invested in notions of identity, and therefore dealt with in an identitarian way. This has not been constructive in resolving the antagonistic relationship between the trans* movement and feminism. We aim to disentangle the antagonism within anti-trans* feminist politics on the one hand, and trans* politics’ responses to that antagonism on the other. In so doing, we argue for a politics of<em> </em>status-based recognition (drawing on Fraser, 2000a, 2000b) instead of identity-based recognition, highlighting individuals’ specific needs in society rather than women’s common interests (drawing on Jónasdóttir, 1991), and conceptualising the intersections of the trans* movement and feminism as mutually shaping rather than as trans* as additive to the feminist project (drawing on Walby, 2007, and Walby, Armstrong, and Strid, 2012). We do this by analysing the main contemporary scholarly debates on the relationship between the trans* movement and feminism within feminist and trans* politics. Unafraid of a polemic approach, our selection of material is strategic and illuminates the specific arguments put forward in the article.

This chapter compares the respective roles of administrative institutions and administrative power on the one hand, and other governmental institutions and powers on the other, in dealing with drug use, possession, and trafficking in China and Victoria (Australia). Comparison of these two jurisdictions provides both opportunities and challenges. Though one is a nation-state, the other a sub-national state within a federation, both have jurisdiction to regulate drug use-related harms and offending. There is thus comparability in terms of jurisdiction. More importantly, the opportunities and challenges for comparison stem from the divergence in fundamental political system; one authoritarian and one liberal democratic, and the nature of the relationship between state and citizen that flows from this. This divergence has implications for selection of both comparative methodology and the subject matter of comparison.

This paper focuses on the relationship between Alexander von Humboldt, the famous German explorer-naturalist and Filippo Parlatore, botanist from Palermo (Sicily, Italy) in the field of botanical geography. Our considerations are based on three letters written by Humboldt to Parlatore in May 1851 and two letters with attachments written by Parlatore in answer to Humboldt in May 1851 and June 1852. The former are preserved in the Biblioteca comunale di Palermo (Palermo City Library) and the latter in the Staatsbibliothek zu Berlin (Berlin State Library). On reading the correspondence it can be inferred how, on the one hand, Humboldt asked Parlatore for verification on some important questions of botanical geography that he intended to cover in the second part (never published) of volume five of his Kosmos, and how, on the other hand, Parlatore diverged in his answers from Humboldt’s intent to search for universal laws to explain the distribution of plants on the planet. In fact, Parlatore was engaging in new lines of research, which, though stemming from Humboldt, were moving towards a modern twodimensional interpretation of natural plant communities according to which vegetation and flora, though interacting, are distinct realities and require different methods of study. The paper includes a portrait of Parlatore and one of Humboldt, a taxonomic table of the plants mentioned by the two scientists in their correspondence and illustrations of a selection of the same plants.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

The Relationship

The purpose of this paper is to re-examine the relationship between the degree of aggregate labour-intensity and the aggregate volume of saving in an economy where a Cobb-6ouglas production function in its traditional form can be assumed to give a good approximation to reality. The relationship in ques¬tion has an obviously important bearing on economic development policy in the area of choice of labour intensity. To the extent that and in the range where an increase in labour intensity would adversely affect the volume of savings, a con¬flict arises between two important social objectives, i.e., higher rate of capital formation on the one hand and greater employment and distributive equity on the other. If relative resource endowments in the economy are such that such a "competitive" range of labour-intensity falls within the nation's attainable range of choice, development planners will have to arrive at a compromise between these two social goals.

In the introduction to his great work of 2005, Framing the Early Middle Ages, Chris Wickham urged not only the necessity of carefully framing our studies at the outset but also the importance of closely defining the words and concepts that we employ, the avoidance ‘cultural sollipsism’ wherever possible and the need to pay particular attention to continuities and discontinuities. Chris has, of course, followed these precepts on a vast scale. My aim in this chapter is a modest one. I aim to review the framing of thirteenth-century England in terms of two only of Chris’s themes: the aristocracy and the state—and even then primarily in terms of the relationship between the two. By the thirteenth century I mean a long thirteenth century stretching from the period of the Angevin reforms of the later twelfth century on the one hand to the early to mid-fourteenth on the other; the reasons for taking this span will, I hope, become clearer during the course of the chapter, but few would doubt that it has a validity.

This article engages with how religion and economy relate to each other in faith-based businesses. It also elaborates on a recurrent idea in theological literature that reflections on different visions of time can advance theological analyses of the relationship between Christianity and capitalism. More specifically, this article brings results from an ethnographic study of two faith-based businesses into conversation with the ethicist Luke Bretherton’s presentation of different understandings of the relationship between Christianity and capitalism. Using Theodore Schatzki’s theory of timespace, the article examines how time and space are constituted in two small faith-based businesses that are part of the two networks Business as Mission (evangelical) and Economy of Communion (catholic) and how the different timespaces affect the religious-economic configurations in the two cases and with what moral implications. The overall findings suggest that the timespace in the Catholic business was characterized by struggling caused by a tension between certain ideals on how religion and economy should relate to each other on the one hand and how the practice evolved on the other hand. Furthermore, the timespace in the evangelical business was characterized by confidence, caused by the business having a rather distinct and achievable goal when it came to how they wanted to be different and how religion should relate to economy. There are, however, nuances and important resemblances between the cases that cannot be explained by the businesses’ confessional and theological affiliations. Rather, there seems to be something about the phenomenon of tension-filled and confident faith-based businesses that causes a drive in the practices towards the common good. After mapping the results of the empirical study, I discuss some contributions that I argue this study brings to Bretherton’s presentation of the relationship between Christianity and capitalism.

Simple Picture

AbstractThis article proposes to narrow the gap between the space of reasons and the space of causes. By articulating the standard phenomenology of reasons and causes, we investigate the cases in which the clear-cut divide between reasons and causes starts to break down. Thus, substituting the simple picture of the relationship between the space of reasons and the space of causes with an inverted and complex one, in which reasons can have a causal-like phenomenology and causes can have a reason-like phenomenology. This is attained by focusing on “swift reasoned actions” on the one hand, and on “causal noisy brain mechanisms” on the other hand. In the final part of the article, I show how an analogous move, that of narrowing the gap between one’s normative framework and the space of reasons, can be seen as an extension of narrowing the gap between the space of causes and the space of reasons.
