Cognitive radio (CR) improves spectrum efficiency to satisfy increasing demands on wireless transmission by dynamic spectrum access without interfering with legacy networks. In 2004, IEEE 802.22 Working Group was formed to develop a standard for wireless regional area networks (WRANs) based on CR technology (Hu et al et al., 2007). It is expected to obtain a broadband access to data networks on...

In their landmark work, Statehouse Democracy: Public Opinion and Policy in the American States, Erikson, Wright, and McIver (1993) study the effects of individual state partisanship and political ideology on state presidential voting. In general, they found that partisanship and ideology affected presidential voting independently of one another. In addition, from 1988 through 1992 (the last yea...

Commercial advertising is the main source of income for TV channels and allocation of advertising time slots for maximizing broadcasting revenues is the major problem faced by TV channel planners. In this paper, the problem of scheduling advertisements on prime-time of a TV channel is considered. The problem is formulated as a multi-unit combinatorial auction based mathematical model. This is a...

In this work, we present an approach to understand the computational methods and decision-making involved in identification of emotions spontaneous speech. The selected task consists Spanish TV debates, which entail a high level complexity as well additional subjectivity human perception-based annotation procedure. A simple convolutional neural model is proposed, its behaviour analysed explain ...

This  study  investigated  the  effect  of  language  complexity  and  group  size  on  knowledge construction in two online debates. Knowledge construction was assessed using Gunawardena et al.’s Interaction Analysis Model (1997). Language complexity was determined by dividing the  number  of  unique  words  by  total  words.  It  refers  to  the  lexical  variation.  The  results showed  that...

We are looking at a linguistic-discursive analysis of the most recurrent strategies argumentation and persuasion in TV debate January 6, 2021 for presidential elections Portugal. In this debate, two candidates opposed, namely Marcelo Rebelo de Sousa - President Republic time, meantime elected second term André Ventura, deputy Assembly candidate Chega party.
 Our focuses on manipulation use...

What are the conditions that generate minority presidents and deadlock in presidential regimes? What is the impact of minority presidents and deadlock on the survival of these regimes? Based on data for all presidential and mixed democracies that existed between 1946 and 1996, I show (1) that characteristics of the electoral and party systems do affect the level of support for the president in ...

This paper examines the impact of the form of government—–presidential or parliamentary—–on fiscal outcomes in democratic systems. Based on data for democracies in 98 countries between 1970 and 2002, it shows that the gross domestic product ratio of the central government budget balance is higher in presidential than in parliamentary democracies. It also shows that this impact is not due to the...
