Characterization, conservation and sustainability of endangered animal breeds in Campania (Southern Italy)  [PDF]
Vincenzo Peretti, Francesca Ciotola, Leopoldo Iannuzzi
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.55A001
Abstract: Conservation of such animal genetic resources and sustainable development of their products seems to be one of the most important steps to be taken to save endangered animal breeds from the widespread use of cosmopolitan and more productive breeds. Indeed, the protection and conservation of biodiversity of animal breeds adapted to particular environmental conditions is essential to prevent irreversible erosion of genes and gene combinations. A special project to characterize and conserve eight endangered breeds of various animal species raised in Campania (southern-Italy) is reported in this paper along detailed descriptions of all breeds. Some strategies for their characterization and conservation are reported and discussed.
Native cattle breeds of Southern Italy: karyological profile
Francesca Ciotola,Sara Albarella,Antonio Contessa,Giulia Pia Di Meo
Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2009.s2.54
Abstract: Italian typical products of animal origin are strictly linked to native breeds. Their protection requires control of their reproductive and productive abilities. Hence the need for karyological studies to identify subjects with chromosome abnormalities linked to hypofertility or sterility. We report the results of karyological analyses carried out from January 2008 to December 2008 on 145 cattle of native breeds (Agerolese, Cinisara, Modicana and Podolica) reared in Southern Italy so as to evaluate and characterize the presence of chromosome abnormalities in subjects with normal phenotypes. Besides the 128 karyologically normal subjects (2n=60, XY and 2n=60, XX), 17 were carriers of rob (1;29) and one male was a carrier of cellular chimerism 2n=60, XX/XY. According to our data there is a high frequency of rob (1;29) in Cinisara and Podolica breeds while in Agerolese there was only one case of rob (1;29) and none in Modicana.
A Colorful Demonstration of Thermal Refraction
Mark Ciotola,Olivia Mah
Physics , 2014,
Abstract: The wave nature of heat flow mechanisms, such as lattice waves is discussed. Tan and Holland's Tangent Law of heat flow refraction is reviewed. A classroom demonstration of heat flow refraction through conductors in series is presented, and sample results are examined for consistency with the Tangent Law. To predict results, the Tangent Law is derived from the Principle of Least Resistance for this demonstration. User-modifiable simulations in Ruby and Ruby on Rails are presented, along with simulation results for various combinations of conductors. Results are interpreted in terms of the Principle of Least Time, illustrating a powerful unification in physics between disparate areas such as optics and thermodynamics.
Efficiency Discounted Exponential Growth (EDEG) Approach to Modeling the Power Progression of a Historical Dynasty
Mark P. A. Ciotola
Physics , 2014,
Abstract: Various approaches to model the progression of a dynasty in terms of power are discussed. The efficiency-discounted exponential growth (EDEG) approach is presented, and the effects of changing decay type and growth rate are demonstrated. The Russian Romanov dynasty is utilized as an example for several of the approaches.
The Use of Materials from Biomass as Construction Materials  [PDF]
Francesca Giglio
Open Journal of Civil Engineering (OJCE) , 2013, DOI: 10.4236/ojce.2013.32A009
Abstract:

The paper describes some studies conducted by the author, about low impact materials and, particularly, on alternative uses of biomass materials for building materials. Italy needs to develop renewable energy sources and agriculture offers many opportunities: biomass, vegetable residues for livestock breeding, food industry waste, organic waste, solid biofuels, biogas, and biofuels, will be the new renewable energy sources. Researches for promoting sustainable development, including chemistry field are increasing interest in the exploitation of vegetal biomass, in particular waste as a raw material for production of bio-products and biofuels. Not always, however, the use of waste materials such as biomass is the most appropriate, or in any case, the one with less energy expenditure. As ever more evident, in fact, the construction sector is approaching the possibility of using these materials for other purposes, combining the demands of saving natural resources, the need for energy efficiency in buildings and production processes.

Public Private Partnerships for Transportation Infrastructure Delivery  [PDF]
Francesca Leccis
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.35004
Abstract:

The term Public Private Partnerships includes different forms of collaboration between the public and the private sector. These formulas are adopted in a constantly increasing number of countries all over the world in order to overcome the chronic lack of funding and ensure the delivery of infrastructure projects. The paper illustrates the vital role of cooperation between public bodies and private entities in the delivery of public transportation infrastructure. In particular, it focuses on toll roads and highways. Key factors of success and risk are identified and illustrated through five case studies from Chile, Hungary, South Africa-Mozambique, United Kingdom and California.

Chromosome fragility in Freemartin cattle
F. Ciotola,V. Peretti,S. Albarella,R. Buonerba
Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2007.1s.85
Abstract: The aim of the present study was to verify chromosome fragility in freemartin cattle using chromosome aberration (CA) and sister chromatid exchange (SCE) tests. A total of eighteen co-twins were investigated. Fourteen animals were identified as cytogenetically chimeric (2n=60, XX/XY) while 4 were classified as normal. Freemartin cattle showed a higher percentage of aneuploid cells (18.64%) and highly significant statistical differences (P < 0.001) in mean values of gaps (4.53 ± 2.05), chromatid breaks (0.26 ± 0.51), and significant statistical differences (P < 0.005) in mean values of chromosome breaks (0.12 ± 0.43) when compared to 10 control animals from single births (aneuploid cells, 11.20%; gaps, 2.01 ± 1.42; chromatid breaks, 0.05 ± 0.22; chromosome breaks, 0.02 ± 0.14).
Identity in Sport Teams  [PDF]
Cristina Zucchermaglio, Francesca Alby
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.23031
Abstract: In this paper we analyze identity in a soccer team using a discursive perspective, in which individual psycho-logical functioning is considered to be built in and through social interactions within groups. Analysis is based on naturally-occurring interactions that were audio recorded during technical meetings before and after the match. The data were collected within an ethnographic investigation of an Italian soccer tam carried out over a two-month period. The results show that the team’s members made rhetorical use of a complex repertoire of their own and others’ social identities, and that two main variables influenced the use of social identity markers: a) the role of the speakers (in particular the “power” role of the coach); b) the result of the match around which the interactive discourse revolved. Against this background, we discuss how narratives and identity positionings were used to achieve specific goals and to perform specific actions, such as the planning of future matches and the interpretation of victories and defeats.
Students’ Metaphors for Defining Their Learning Experience with Audio-Visible versus Invisible Authors. Results from a Case Study in a Social Science Discipline  [PDF]
Terry Inglese, Francesca Rigotti
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23025
Abstract: This article summarizes an instructional experience designed and conducted at the University of Lugano – Communication Sciences – (Switzerland) within a Political Theory’s freshmen course, which involved disciplines like: philosophy, political science and epistemology. We offered students two types of authors to be learned: one through a multimedia video interview in combination with written texts of these authors, defined as the audio-visible authors, and one type of author offered only through a text-based format (the invisible author). We gathered quantitative data (students’ performance on their written exam compositions, their grades; the number of written words they wrote; and the number of times students mentioned the two types of authors in their written compositions). We also collected qualitative data (through semi-structured interviews and thinking aloud protocols), analyzing the metaphors students used to define the reading and learning experience with the audio-visible and the invisible authors. Results show that students perform better when the author to be studied is offered with more media instructional supports, they tend to establish a social relationship with the author, and the quality of their critical thinking and the level of interest in a new subject both increase. The article is divided in three parts: we will first give some definitions of what a metaphor is; second, we will describe our case study and the results of the data analysis; third, we will discuss the results.
An Induced Demand Model for High Speed 1 in UK  [PDF]
Francesca Pagliara, John Preston
Journal of Transportation Technologies (JTTs) , 2013, DOI: 10.4236/jtts.2013.31005
Abstract:

Induced travel is an important component of travel demand and increasing attention has been paid to building analytical model to get more precise travel demand forecasting. In general, induced demand can be defined in terms of additional trips that would be made if travel conditions improved (less congested, lower vehicle costs or tolls). In this paper the induced demand resulting from higher design speeds and, therefore by less travel time, for the High Speed 1 in UK will be modelled on the basis of the relationship between existing High Speed Rail demand (dependent variable) to existing High Speed Rail travel times and costs. The covariates include socioeconomic variables related to population and employment in the zones connected by the High Speed Rail services. This model has been calibrated by mean of a before and after study carried on the corridor, when the new High Speed Rail services was introduced. Elasticities of induced travel (trips and VMT) have been computed with respect to fares, travel time and service frequency.
