Kodato, Sergio;Silva, Ana Paula Soares da;
Psicologia: Reflex?o e Crítica , 2000, DOI: 10.1590/S0102-79722000000300018
Abstract: this research is an investigation of some factors associated to homicides committed against adolescents, at the city of ribeir?o preto (sp), in which, during the period of 1995-1998, 101 children and adolescents were killed. the collect and analysis of data were made throughout the association of the following methods: sociographics data enrollment, analysis of taken lawsuits in the local prosecuting counsel; participant observation of the local internment institution, destined to adolescents authors of infraction acts; interview with intern adolescents for homicide acts (n=8). as a result one may state that the life conditions that ends on death of adolescents are product of a synchronization of factors, where, besides the fragility of institutions, one may observe determinants the dispute for appropriation of goods, conflict of financial interests, drug traffic and, a mode of producing of interpersonal relationship, of which resolution of conflictive situation materializes in non mediate and violent ways.

Vietta, Edna Paciência;Kodato, Sérgio;Furlan, Reinaldo;
Revista Latino-Americana de Enfermagem , 2001, DOI: 10.1590/S0104-11692001000200014
Abstract: this work is a result of authors' reflection on the necessity of conceptual changes in the area of mental health. the authors aimed at understanding the essential aspects involving the theme according to the conception of paradigm, as well as the process in which the crisis appears emerging anomalies and pointing out the inefficiency of the present paradigm. thus, they suggested a change from the actual model to another one based on a perspective that emphasizes patient's freedom and the relational character of human expressiveness.
Desirability of a standard notation for fisheries assessment  [PDF]
Sergio Ragonese, Sergio Vitale
Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.48057

The worldwide increase of the publications concerning the assessment of marine renewable living resources is highlighting long-standing problems with symbols and annotations. Starting from the symbols presented within the classic fisheries masterpieces produced, mainly in the fifty of the last century, a first “Milestone” list was organised. Thereafter, the pertinent literature was (not exhaustively) browsed in order to integrate this Milestone list on the base of a set of decisional criteria. The present contribution consists in using the Latin letters as well established symbols for the corresponding parameters, leaving free to specific use (with few historical exceptions) the Greek letters in view to open a discussion among all the fisheries scientists and bodies in order to move towards a common language and better communication standards.

On the k–Lucas Numbers of Arithmetic Indexes  [PDF]
Sergio Falcon
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.310175
Abstract: In this paper, we study the k–Lucas numbers of arithmetic indexes of the form an+r , where n is a natural number and r is less than r. We prove a formula for the sum of these numbers and particularly the sums of the first k-Lucas numbers, and then for the even and the odd k-Lucas numbers. Later, we find the generating function of these numbers. Below we prove these same formulas for the alternated k-Lucas numbers. Then, we prove a relation between the k–Fibonacci numbers of indexes of the form 2rn and the k–Lucas numbers of indexes multiple of 4. Finally, we find a formula for the sum of the square of the k-Fibonacci even numbers by mean of the k–Lucas numbers.
A Quantistic Interpretation of the Relationship between the Earth-Core and the Atmosphere  [PDF]
Sergio Manzetti
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.44046

The atmospheric behaviour of air is largely governed by low and high pressure systems. However, the relationship between these systems is not linear, as winds, sea temperatures and solar intensity modulate their dynamics and reduce predictability. Several other factors are known to affect these atmospheric dynamics, such as solar cycles. Recent evidence shows however that the earth’s gravitational field can be quantized in terms of quantum numbers, as recently published in Nature. The implications of this relationship between gravity and quantum numbers give rise to the possible key role of a quantum behaviour of gravity in affecting the formation of high- and low-pressure systems. In this letter, the author suggests a relation between the recently observed quantized nature of gravity, the weight of air and the formation of Low and High pressure areas in the atmosphere. The theory is novel and can aid in the understanding of interplay between the earths core forces, the gravitational behaviour and the atmospheric dynamics. There are however several parts of this theory that need further development, and an initial expression of this putative relationship is introduced.

Relationships between Some k -Fibonacci Sequences  [PDF]
Sergio Falcon
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.515216
Abstract: In this paper, we will see that some -Fibonacci sequences are related to the classical Fibonacci sequence of such way that we can express the terms of a k -Fibonacci sequence in function of some terms of the classical Fibonacci sequence. And the formulas will apply to any sequence of a certain set of k' -Fibonacci sequences. Thus we find k -Fibonacci sequences relating to other k -Fibonacci sequences when σ'k is linearly dependent of \"\".
Causal Groupoid Symmetries  [PDF]
Sergio Pissanetzky
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.54059

Proposed here is a new framework for the analysis of complex systems as a non-explicitly programmed mathematical hierarchy of subsystems using only the fundamental principle of causality, the mathematics of groupoid symmetries, and a basic causal metric needed to support measurement in Physics. The complex system is described as a discrete set S of state variables. Causality is described by an acyclic partial order w on S, and is considered as a constraint on the set of allowed state transitions. Causal set (S, w) is the mathematical model of the system. The dynamics it describes is uncertain. Consequently, we focus on invariants, particularly group-theoretical block systems. The symmetry of S by itself is characterized by its symmetric group, which generates a trivial block system over S. The constraint of causality breaks this symmetry and degrades it to that of a groupoid, which may yield a non-trivial block system on S. In addition, partial order w determines a partial order for the blocks, and the set of blocks becomes a causal set with its own, smaller block system. Recursion yields a multilevel hierarchy of invariant blocks over S with the properties of a scale-free mathematical fractal. This is the invariant being sought. The finding hints at a deep connection between the principle of causality and a class of poorly understood phenomena characterized by the formation of hierarchies of patterns, such as emergence, selforganization, adaptation, intelligence, and semantics. The theory and a thought experiment are discussed and previous evidence is referenced. Several predictions in the human brain are confirmed with wide experimental bases. Applications are anticipated in many disciplines, including Biology, Neuroscience, Computation, Artificial Intelligence, and areas of Engineering such as system autonomy, robotics, systems integration, and image and voice recognition.

Axisymmmetric Empty Space: Light Propagation, Orbits and Dark Matter  [PDF]
Sergio Giardino
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.515141
Abstract: This study presents an axisymmetric solution of the Einstein equations for empty space. The geometry is studied by determining its Petrov classification and killing vectors. Light propagation, orbital motion and asymptotic and Newtonian limits are also studied. Additionally, cosmological applications of the geometry are also outlined as an alternative model for the inflationary universe and as a substitute for dark matter and quintessence.
Causal Groupoid Symmetries and Big Data  [PDF]
Sergio Pissanetzky
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.521327
Abstract: The big problem of Big Data is the lack of a machine learning process that scales and finds meaningful features. Humans fill in for the insufficient automation, but the complexity of the tasks outpaces the human mind’s capacity to comprehend the data. Heuristic partition methods may help but still need humans to adjust the parameters. The same problems exist in many other disciplines and technologies that depend on Big Data or Machine Learning. Proposed here is a fractal groupoid-theoretical method that recursively partitions the problem and requires no heuristics or human intervention. It takes two steps. First, make explicit the fundamental causal nature of information in the physical world by encoding it as a causal set. Second, construct a functor F: C\"\" C′ on the category of causal sets that morphs causal set C into smaller causal set C′ by partitioning C into a set of invariant groupoid-theoretical blocks. Repeating the construction, there arises a sequence of progressively smaller causal sets C, C′, C″, The sequence defines a fractal hierarchy of features, with the features being invariant and hence endowed with a physical meaning, and the hierarchy being scale-free and hence ensuring proper scaling at all granularities. Fractals exist in nature nearly everywhere and at all physical scales, and invariants have long been known to be meaningful to us. The theory is also of interest for NP-hard combinatorial problems that can be expressed as a causal set, such as the Traveling Salesman problem. The recursive groupoid partition promoted by functor F works against their combinatorial complexity and appears to allow a low-order polynomial solution. A true test of this property requires special hardware, not yet available. However, as a proof of concept, a suite of sequential, non-heuristic algorithms were developed and used to solve a real-world 120-city problem of TSP on a personal computer. The results are reported.
