Budo as philosophical background of Karate-Do: does the training method really matter?
Background. The practice of Japanese originated martial arts, like Karate-Do, is associated with an individual “path of enlightment” or the way of living (Do), that surpasses the athletic practice for itself. The concept of Budo, with all values, moral principles and patterns of behaviour, is traditionally linked to this path or way, being the philosophical background of the practice. The globalisation of the Karate-Do have created two main ways or training methods with different main goals – traditional one and sports Karate-Do.
Problem. The main objective of this study is to compare the evaluations of different Budo- associated aspects, values, principles and domains, to find the differences between karateka who are engaged in both training methods.
Method. A questionnaire was applied, in Portugal, to a group of 78 karateka with more than two years of continued training, who are engaged or use a traditional or sports training method.
Results. The results show a high and similar evaluation scores of all items questioned on both training methods, only with single and not consistent differences.
Conclusion. Without generalising, we can assume that karateka observe the philosophical background of Karate-Do (Budo) in only one way, even when they are engaged in different methods of practice with different main goals. So, Karate-Do philosophy is one,only daily practices in dojo and goals differ. However, further investigation is needed to support these conclusions
The systemic dimension of operational decision in complex systems work
This paper refers to some of my research findings on Decision Making processes in complex systems work. Starting as a complex cognitive process strongly contextualized in the operating environment, it ends up, in complex systems work, as an equally complex network of actors and systems (human and technological) that are confronted, in real time, with uncertainty , a large amount of information and feedback and with multiple standards and operating procedures...Complex systems work; Operational Decision; Mental Model; Situational awareness; Systemic decision
Elastic shocks in relativistic rigid rods and balls
We study the free boundary problem for the "hard phase" material introduced
by Christodoulou, both for rods in (1+1)-dimensional Minkowski spacetime and
for spherically symmetric balls in (3+1)-dimensional Minkowski spacetime.
Unlike Christodoulou, we do not consider a "soft phase", and so we regard this
material as an elastic medium, capable of both compression and stretching. We
prove that shocks must be null hypersurfaces, and derive the conditions to be
satisfied at a free boundary. We solve the equations of motion of the rods
explicitly, and we prove existence of solutions to the equations of motion of
the spherically symmetric balls for an arbitrarily long (but finite) time,
given initial conditions sufficiently close to those for the relaxed ball at
rest. In both cases we find that the solutions contain shocks if and only if
the pressure or its time derivative do not vanish at the free boundary
initially. These shocks interact with the free boundary, causing it to lose
regularity.Comment: 22 pages, 3 figures; v2: small changes, matches final published

Induced pluripotent stem cells, a giant leap for mankind therapeutic applications
Induced pluripotent stem cells (iPSC) technology has propelled the field of stem
cells biology, providing new cells to explore the molecular mechanisms of
pluripotency, cancer biology and aging. A major advantage of human iPSC,
compared to the pluripotent embryonic stem cells, is that they can be generated
from virtually any embryonic or adult somatic cell type without destruction of
human blastocysts. In addition, iPSC can be generated from somatic cells
harvested from normal individuals or patients, and used as a cellular tool to
unravel mechanisms of human development and to model diseases in a manner
not possible before. Besides these fundamental aspects of human biology and
physiology that are revealed using iPSC or iPSC-derived cells, these cells hold an
immense potential for cell-based therapies, and for the discovery of new or
personalized pharmacological treatments for many disorders. Here, we review
some of the current challenges and concerns about iPSC technology. We
introduce the potential held by iPSC for research and development of novel
health-related applications. We briefly present the efforts made by the scientific
and clinical communities to create the necessary guidelines and regulations to
achieve the highest quality standards in the procedures for iPSC generation,
characterization and long-term preservation. Finally, we present some of the
audacious and pioneer clinical trials in progress with iPSC-derived cells.info:eu-repo/semantics/publishedVersio
Homogeneous cosmologies from the quasi-Maxwell formalism
We show how to use the quasi-Maxwell formalism to obtain solutions of
Einstein's field equations corresponding to homogeneous cosmologies - namely
Einstein's universe, Godel's universe and the Ozsvath-Farnsworth-Kerr class I
solutions - written in frames for which the associated observers are
stationary.Comment: 15 pages, references adde
CSR and Social Marketing: What is the desired role for Universities in fostering Public Policies?
The paper aims to identify the role of Universities in fostering public policies, through the promotion of social responsibility, and the implementation of social marketing initiatives. This innovative approach is particularly interesting since the literature does not cover, until now, the importance of adopting a social responsibility strategy within Universities, in order to foster public policies for development. First, Corporate Social Responsibility should be developed at Universities. For this purpose, an integrative approach that embraces marketing, economic, ecological, and social aspects is proposed, through the design of a strategic action plan, which includes three operational levels: analysis, implementation and assessment. Second, in order to foster the impact of public policies for development, social marketing initiatives should be implemented among institutional and social networks where Universities assume an increasing strategic role.Corporate Social Responsibility; Government Policy; Social Marketing
