A New Interpretation of the Hubble Law  [PDF]
Pascal Churoux
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.69127
Abstract: We propose a new interpretation of Hubble law. Waves are observed in the observer space-time. It defines the observer proper time T. Space-time is composed of three spatial dimensions and three temporal parameters: proper-time s of the observed object, proper time T of the observer and integration time t (currently considered as relative time). Time origin is the birth of the universe. So, universe is stable; it can be seen as the comobile space of expansion theory. When changing space-time from the source to the observer, waves are seen cooling; this explains the redshift effect. The distance is defined as the product of the delay time with the local speed of light of the observer. The mistake between t and T can explain why universe is viewed as not only in expansion but also in acceleration whereas we think it is stable.
The Relativity of Cosmic Time: The Universe Is a Black Hole  [PDF]
Pascal Churoux
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.613188
Abstract: Up to now, cosmology metrics have been based on Einstein relativity, established in 1905. Hubble has discovered the correlation between redshift and distance. Cosmology interprets the redshift as an expansion effect a(t) through the ΛCDM model. We have proposed a new theory to explain Hubble law. The theory has been validated against observation data. It proposes a new approach of time which introduces the cosmic time tc. Cosmic time is an absolute reference to universe. It is zero at the edge with tc = 0, tc = T at the observer position and tc = s for any source between the edge and the observer, with T > s > 0. This theory acts like the relativity of space-time. The redshift is interpreted as a perspective parameter p(tc) = tc/T. Using gravitation, it is the Einstein effect applied to the uni-verse. This paper comments and interprets further consequences of this new theory. We emphasize the difference between duration (as usually used in classical cosmologic metrics) and the cosmic time tc as a notion of date. It induces two related effects: relativity of speed of light and time stretching. We explain why the cosmological standard model is not well suited to describe the Hubble law, to describe the universe. We also explain why gravitation and temperature increase when going from the center to the edge of the universe, when going from present to birth. The model has no use of black energy. As a consequence, the universe is seen as a black hole created by the cosmic time shock wave when tc = 0.
The End of Voters in Europe? Electoral Turnout in Europe since WWII  [PDF]
Pascal Delwit
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.31007

Over the past twenty years, the scientific community and politicians in consolidated democracies have been regularly alarmed by political and electoral participation, portrayed as undergoing a brutal and linear decline. Each election is now scrutinized in terms not only of its results but also of its level of electoral turnout. This paper deals with two important issues—the reality of changes in electoral turnout in Europe and the impact of the institutional constraint of compulsory voting in voter turnout levels—through an analysis of 402 elections held in thirty-five States from 1944 until December, the 31st 2009. We do observe a contemporary erosion of voter turnout but at this stage voters are not so impossible to find as some claim they are. Furthermore, the assumption that interest in, and the importance of, compulsory voting as an institutional constraint encouraging voter turnout is confirmed.


The Catastrophe Map of a Two Period Production Model with Uncertainty  [PDF]
Pascal Stiefenhofer
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.48A016

This paper shows existence and efficiency of equilibria of a two period production model with uncertainty as a consequence of the catastrophe map being smooth and proper. Its inverse mapping defines a finite covering implying finiteness of equilibria. Beyond the extraction of local equilibrium information of the model, the catastrophe map renders itself well for a global study of the equilibrium set. It is shown that the equilibrium set has the structure of a smooth submanifold of the Euclidean space which is diffeomorphic to the sphere implying connectedness, simple connectedness, and contractibility.

Topological Properties of the Catastrophe Map of a General Equilibrium Production Model with Uncertain States of Nature  [PDF]
Pascal Stiefenhofer
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.517259
Abstract: This paper shows existence and efficiency of equilibria of a production model with uncertainty, where production is modeled in the demand function of the consumer. Existence and efficiency of equilibria are a direct consequence of the catastrophe map being smooth and proper. Topological properties of the equilibrium set are studied. It is shown that the equilibrium set has the structure of a smooth submanifold of the Euclidean space which is diffeomorphic to the sphere implying connectedness, simple connectedness, and contractibility. The set of economies with discontinuous price systems is shown to be of Lebesgue measure zero.
Production in General Equilibrium with Incomplete Financial Markets  [PDF]
Pascal Stiefenhofer
Journal of Mathematical Finance (JMF) , 2016, DOI: 10.4236/jmf.2016.62025
Abstract: This paper considers a general equilibrium model with incomplete financial markets where production sets depend on the financial decisions of the firms. In the short run, firms make financial choices in order to build up production capacity. Given production capacity firms make profit maximizing production decisions in period two. We provide the conditions of existence of equilibria.
Existence of Financial Equilibria in a General Equilibrium Model with Piece-Wise Smooth Production Manifolds  [PDF]
Pascal Stiefenhofer
Journal of Mathematical Finance (JMF) , 2017, DOI: 10.4236/jmf.2017.73035
Abstract: This paper considers a general equilibrium model with production and uncertainty. It is postulated that the firm finances its production capacity through the stock market and that its operational costs are covered through revenues. It is assumed that firms have linear technologies exhibiting constant returns to scale. Their production sets are piece-wise smooth convex manifolds. By method of regularization, it is shown using transversally theory that financial equilibria exists.
Belgian Communism in the Light of Its Vanishing (1976-1994)  [PDF]
Pascal Delwit
Open Journal of Political Science (OJPS) , 2018, DOI: 10.4236/ojps.2018.83023
Abstract: In the 1987 national elections, the Communist Party of Belgium (PCB-KPB) lost all parliamentary representation for the first time since 1925. This failure reflects the accelerated collapse of Belgian Communism in just a decade. The events of 1989 and 1991 in Central and Eastern Europe and in the USSR will then confirm the de facto disappearance of the PCB-KPB. The article goes back to the roots of the decline of a medium-size Communist Party, but showed political and social relevance from 1925 to 1985. The decline is due to the industrial and socio-demographic dramatic changes. The paper also tackles the political choices made in the seventies and eighties to understand it. In particular, it embraces the internal paralysis of the party faced with the challenges posed to all the European Communist Parties at this time, and its inability to deal with them.
Conspicuous Ethical Consumption  [PDF]
Pascal Stiefenhofer
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.91001

This paper considers a group of consumers who have preferences over how a good is produced and distributed, rather its traits alone. Moreover, it is hypothesized that ethical preferences also depend on prices, and that prices inform consumers about the way goods are produced and distributed. The concept of conspicuous ethics is introduced in order to motivate the consumption of ethically produced goods. The paper states the assumptions and conditions representing the consumption behavior of the ethical consumer. It is shown that a price-dependent direct utility function provides the necessary structure in the characterization of the consumption behavior of the ethical consumer.

Using Nursery Rhymes to Foster Phonological and Musical Processing Skills in Kindergarteners  [PDF]
Jonathan Bolduc, Pascal Lefebvre
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.34075
Abstract: The aim of this study was to assess the efficiency of four learning conditions to develop phonological and musical processing skills through a set of 10 nursery rhymes. According to the analysis of the teachers’ practices, eight kindergarten classes (n = 100 kindergarteners) were paired and assigned to one of the following conditions: 1) music, 2) language, 3) combined [music and language], and 4) passive listening (control classes). Participants in conditions 1, 2, and 3 were met for 40 minutes per week over a ten-week period. In condition 1, the nursery rhymes were supplemented by musical activities and in condition 2 by language activities. Condition 3 was a combination of activities from conditions 1 and 2. In condition 4, children listened to a recording of the same nursery rhymes for 15 minutes daily during free exploration periods. No intervention was proposed for this control condition. All participants were evaluated using the same phonological and musical processing measures prior to and after the implementation of the program. Results indicated that children in conditions 1, 2 and 3 significantly improved their phonological awareness and their invented spelling skills at post-test. However, only the two conditions in which the music component was integrated enhanced significantly their results at the verbal memory task. Children in conditions 1, 3 and 4 enhanced tonal and rhythm perception skills. This study demonstrated that supplementing nursery rhymes with language activities is an efficient manner to develop emergent literacy skills, but the addition of musical activities could also boost phonological processing skills.
