An Ethical Approach to the Concept of Toleration: Understanding Tolerance as a Political Virtue  [PDF]
Ivón Cepeda Mayorga
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.44059
Abstract: The concept of toleration is commonly argued in political discourses and debates, when people refer to diversity and pluralism, as a form of respect and understanding. However, this does not represent an improvement at the moment of dealing with issues where a variety of values, conceptions and beliefs arises. In addition, even though when the idea of toleration was developed during Enlightenment, nowadays it seems to lead to a misconception of the term, following a connotation of a passive indifference about diversity. Due to this, the main objective of this text is to analyze the concept of toleration from an ethical perspective that allows thinking about it in terms of a political virtue needed to face the challenges of diversity inside society. In order to show this, the text presents an analysis of different conceptions of the term, in order to highlight the positive notion of toleration; after that, the text moves on, reviewing the idea of toleration from a hermeneutical perspective, as a form to reinforce the positive characteristics of the term, and path to solve the query between tolerance and intolerance. Finally, as a conclusion, it underlines that understanding the concept of toleration from an ethical perspective implies a praxis develop in daily circumstances.
Impact of Integrated Arts Therapy: An Intervention Program for Young Female Offenders in Correctional Institution  [PDF]
Kristi K?iv, Lii Kaudne
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.61001
Abstract: The aim of the study was to evaluate the impact of program of integrated arts therapy on young female delinquents’ who experienced emotional and behavioral problems in a correctional institution. The outlined intervention was introduced as part of a curriculum involving art therapy, drama therapy, music therapy, and dance/movement therapy sessions that were facilitated twice a week during a 5-week period. A quasi-experimental design was used where an intervention group (N = 12) and a control group (N = 17) members aged 14 - 17 years were evaluated at two time points. A self-report version of Strengths and Difficulties Questionnaire (SDQ) and a modified Behavior Checklist (BC) were used prior to and after the intervention to screen for conduct, emotional, peer problems, hyperactivity, and prosocial behavior, and to investigate the frequencies of aggressive, withdrawn and prosocial behavior. There were statistically significant reductions in three of the five emotional and behavioral problems measured by the SDQ, including conduct and emotional problems, an increase of prosocial behavior, and significant differences in two domains measured by the BC: decrease in frequencies of aggressive behavior and increase of prosocial behavior.
The Difficult Airway: A New Simplified Approach to an Old Complex Problem  [PDF]
Iván Mauricio Alvarado Arteaga
Open Journal of Anesthesiology (OJAnes) , 2017, DOI: 10.4236/ojanes.2017.78023
Abstract: Difficult airway situations are a major cause of morbidity, mortality and malpractice claims in anesthetic practice and other critical care settings. Although infrequent, they are serious and complex situations where many variables interact. Among these variables, quick and accurate rescuer decision-making is a major outcome determinant. Emerging evidence, recent advances in technology and development of new devices have provided new tools to deal with the problem, but still, basic underlying principles of management remain. Based on the available evidence and expert consensus, multiple guidelines and algorithms have been published, but they may have limited applicability, contain confusing and ambiguous recommendations or address very specific clinical situations. This narrative review attempts to summarize, organize and consolidate current trends and supported recommendations of the updated guidelines in one practical, concise and unified guide, proposing a simple, intuitive and novel algorithm.
A Genetic Algorithm for the Split Delivery Vehicle Routing Problem  [PDF]
Joseph Hubert Wilck IV, Tom M. Cavalier
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.22024
Abstract: The Split Delivery Vehicle Routing Problem (SDVRP) allows customers to be assigned to multiple routes. Two hybrid genetic algorithms are developed for the SDVRP and computational results are given for thirty-two data sets from previous literature. With respect to the total travel distance and computer time, the genetic algorithm compares favorably versus a column generation method and a two-phase method.
A Construction Heuristic for the Split Delivery Vehicle Routing Problem  [PDF]
Joseph Hubert Wilck IV, Tom M. Cavalier
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.22018
Abstract: The Split Delivery Vehicle Routing Problem (SDVRP) is a relaxation of the Capacitated Vehicle Routing Problem (CVRP) where customers may be assigned to multiple routes. A new construction heuristic is developed for the SDVRP and computational results are given for thirty-two data sets from previous literature. With respect to the total travel distance, the construction heuristic compares favorably versus a column generation method and a two-phase method. In addition, the construction heuristic is computationally faster than both previous methods. This construction heuristic could be useful in developing initial solutions, very quickly, for a heuristic, algorithm, or exact procedure.
Conditions Where the Chaotic Set Has a Non-Empty Residual Julia Set for Two Classes of Meromorphic Functions  [PDF]
Patricia Domínguez, Iván Hernández
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.411A2004
Abstract:

We define the Fatou and Julia sets for two classes of meromorphic functions. The Julia set is the chaotic set where the fractals appear. The chaotic set can have points and components which are buried. The set of these points and components is called the residual Julia set, denoted by \"\", and is defined to be the subset of those points of the Julia set, chaotic set, which do not belong to the boundary of any component of the Fatou set (stable set). The points of \"\" are called buried points and the components of \"\" are called buried components. In this paper we extend some results related with the residual Julia set of transcendental meromorphic functions to functions which are meromorphic outside a compact countable set of essential singularities. We give some conditions where \"\".

The Efficiency Analysis of the Exhaust Air Heat Pump System  [PDF]
Alo Mikola, Teet-Andrus K?iv
Engineering (ENG) , 2014, DOI: 10.4236/eng.2014.613093
Abstract: This paper is based on long term parameter measurements of the exhaust air heat pumps (EAHP) system in a new built apartment building. The building was equipped with an exhaust air ventilation system and exhaust air heat pump for ventilation heat recover. The results of the measurements show that the COP of the EAHP is mainly related to the temperature graph of the heating system and the supply temperature of domestic hot water (DWH). During the measurement period some other impact factors, such as the quality of maintenance, the nighttime temperature graph of the heating system, the reduction of the exhaust air flows in case of low temperatures, mistakes in designing and low building quality, have also played a role. An analysis of energy consumption shows that in winter conditions the COP is about 3.0 and in the transition period about 3.3. The energy recovery value of the EAHP is 0.5.
Bilinear Model Proposal for Seismic Analysis Using Triple Friction Pendulum (TFP) Bearings  [PDF]
Iván Delgado, Roberto Aguiar, Pablo Caiza
Open Journal of Civil Engineering (OJCE) , 2017, DOI: 10.4236/ojce.2017.71002
Abstract:
An analytical model is presented for seismic analysis of triple friction pendulum bearings and validated using 81 bearing tests, each subjected to three cycles, with a duration of 12 seconds and using 250, 200 and 100 tons vertical loads. The main objective is to develop formulas for bilinear behavior using maximum, average and minimum friction coefficients to check which is the closest to the real behavior in the laboratory tests and comparatives curves plotting to observe the standard derivation. Parameters such as friction coefficients, effective stiffness, damping factor and vibration periods are analyzed to understand the structural behavior of the TPF bearings.
Development of a Low Cost Pulsed Laser Deposition System for Thin Films Growth  [PDF]
Marcos Iván Oliva, Carlos Iván Zandalazini, Juan Carlos Ferrero, Hector Raúl Bertorello
Modern Instrumentation (MI) , 2012, DOI: 10.4236/mi.2012.14006
Abstract: .Pulsed Laser Deposition (PLD) is a powerful technique to grow thin films. Oxides, Magnetics and superconducting materials have been obtained by PLD and theirs properties are strongly dependent of deposition parameters. The construction of a simple and cheap PLD system that is suitable for growing various thin films, including magnetic materials, controlling some deposition parameters is presented. The design characteristics and construction are presented for each one of the devices that compose this PLD system. The equipment has the possibility of carrying out films deposition using up to five targets under controlled atmosphere and substrate temperature. The system also allows controlling the cool off sample time after growing up films at high temperatures. A wide range of relative speeds between target and substrate axial rotation can be externally controlled. With the configuration and the dimensions adopted in their construction, a PLD system of great experimental flexibility is achieved, at a very low cost regarding the commercial systems. To evaluate their performance and effectiveness, the deposition characteristics of a BaFe12O19 film on (0001) sapphire substrate is presented.
