The Fall of Rome and the Decay of our Present Civilisation – A Repetitive Process? – The Decay of “Gods”

2014

Abstract Attacked and weakened, especially in the last three centuries, both from inside and outside, Rome and the Western Roman Empire will fall in 476 A.D. Actually, what were the causes? Hit and weakened by the present global economic-financial crises – and not only – our European civilisation faces some of the highest risks. Often, people say it is a real collapse. Are the causes of these falls – of the European-type civilisation – similar? And being familiar with Roman experience, how can we prevent such harmful processes? Further, we try to provide a few answers in this respect.

Supporting Dispute Handling in E-Commerce Transactions, a Framework and Related Methodologies

2004

An E-commerce transaction is a means to conduct particular commercial activities using the global digital E-commerce infrastructure. We concentrate here on business to customer (B-to-C) E-commerce transactions. These transactions are based on protocols offered by the global infrastructure, primarily the Internet. Using electronic means to do business can greatly improve the efficiency of the business transactions. It, however, poses some problems that were rarely considered to be important before. One class of problems is caused by the behavior of untrusted participants. For reasons such as dishonesty, disputes may arise. In the general case, when a dispute arises an untrustworthy participa…

DenseYOLO: Yet Faster, Lighter and More Accurate YOLO

2020

As much as an object detector should be accurate, it should be light and fast as well. However, current object detectors tend to be either inaccurate when lightweight or very slow and heavy when accurate. Accordingly, determining tolerable tradeoff between speed and accuracy of an object detector is not a simple task. One of the object detectors that have commendable balance of speed and accuracy is YOLOv2. YOLOv2 performs detection by dividing an input image into grids and training each grid cell to predict certain number of objects. In this paper we propose a new approach to even make YOLOv2 more fast and accurate. We re-purpose YOLOv2 into a dense object detector by using fine-grained gr…

A Proposal for an Automatic Stabilizer in Social Justice

2019

Abstract Generally, social justice has two sides which are intercorrelated and inter-dependend: a) constitutive social justice (for example, the so called commutative social justice); b) regulative social justice (for example, the so called distributive social justice). The paper approaches the regulative social justice, more exactly, an automatic mechanism to get it. To this end, an automatic stabilizer to provide distributive social justice, according to the Rawlsian principle of difference. Such an automatic stabilizer is grounded on the wealth, more precise, on the share of the wealth which is not invested in order to benefit to the more disadvantaged class of the society. Paper does no…

A Control Problem for a Class of Epidemics

2003

We consider a mathematical model corresponding to a class of epidemics. Controlling an epidemic is usually difficult. To implement the control policy suggested by a mathematical analysis in the real world is never easy. However, suggestions can be given to the public authorities about the effects of a particular control policy, and in this sense analysis and simulation by mathematical models becomes a powerful tool.

A family of experiments to generate graphical user interfaces from BPMN models with stereotypes

2021

Abstract Context: A significant gap separates Business Process Model and Notation (BPMN) models representing processes from the design of Graphical User Interfaces (GUIs). Objective: This paper reports on a family of experiments to validate a method to automatically generate GUIs from BPMN models using stereotypes complemented with UML class primitives, and transformation rules. Method: We conducted two replications (23 and 31 subjects respectively) in which we compared two methods to generate GUIs from BPMN models; one automatic (using Stereotyped BPMN models) and one manual (using Non-stereotyped BPMN models). The study focuses on comparing effort, accuracy, and satisfaction (in terms of …

“Piero Sraffa’s Lectures on the Advanced Theory of Value 1928 - 1931 and the rediscovery of the classical approach”

2005

Sraffa's Lectures on the Advanced Theory of Value 1928–1931 and his two preparatory Notes of summer and November 1927 provide a wealth of material, up to now unpublished, for a reconstruction of the early stage of his inquiry into the cognate fields of pure economic theory and its history. The three manuscripts show that in the late 1920s Sraffa rejected the Marshallian constant-cost interpretation of classical economics, an interpretation to which he had adhered in his 1925 and 1926 papers. Moreover, in the Lectures, Sraffa presents for the first time his own interpretation of classical economics based on the concepts of surplus, physical real costs and asymmetric treatment of distributive…

10. Political liberalism and the preventive containment of unreasonable beliefs and behavior

2015

This paper examines the ways in which illiberal and unreasonable views can be legitimately contained in a politically liberal society, and discusses some of the pressing reasons to undertake, or abstain from, such measures. Theoretical background for the discussion is provided by Rawlsian political liberalism. The paper focuses on the particular justification for the preventive containment of unreasonable views offered by Jonathan Quong (2011). It is claimed that Quong’s approach raises some significant worries (not unrelated to the ‘third-order pathologies’ discussed above in Chapter 2). The suggestion is put forward that political liberals would do well to pay more attention to respect an…

Challenging the Rule of Political Liberalism

2020

Abstract The origin of the ongoing conflict between the EU and Poland may, according to the author, partly be subscribed to the EU-institutions conceptualization of the rule of law. This conceptualization, which in the article is referred to as “the rule of political liberalism”, establishes a particular set of legal institutional and substantial frames and limits for national democratic politics. Granted that the rule of law is an inherently contested concept, the author deconstructs the rule of political liberalism, reveals its weaknesses and ideological bias and proposes an alternative understanding of the rule of law. “The rule of pragmatism” is based on a pragmatic conceptualization of…
