The Philosophy-Psychology Linkage  [PDF]
Amos Avny
Open Journal of Philosophy (OJPP) , 2018, DOI: 10.4236/ojpp.2018.83016
Abstract: The Essay explores two questions about the subject: a. whether exist any linkage between Philosophy and Psychology, and b. what is the nature of this linkage? Actually, the Author answers that such a linkage already exists. In fact, these two disciplines are like two sides of the same coin, they are complementary rather than competitive. For clarifying this argument the Author discusses 3 example cases, examining the whole individual-organization complex. The Essay describes Adam and Eve’s nature and curiosity, qualities that empowered them in their search for knowledge. This behavior also made them the fore-parents of all explorers, pioneers and researchers who followed them. Further, the Author indicates how wrong use of ideological declarations hurts individuals and subdues them. Finally, the Author advocates the introducing of the “Normal Distribution Method” and the “Bell type Curve” as main tools in teaching and studying Social Sciences.
THE NATURE OF GLOBALIZATION
Amos Avny
Lex et Scientia , 2007,
Abstract: Following the technological advancement and the democratization process the Globalization is one of the most affecting powers in world economy at present. The Globalization combines several process: a global reallocation of industries, a massive expansion of world trade, a rapid growth of merging and acquisitions trends, a significant moves of capital from one country to another, an increased power of global and regional trade organizations and a growth of lifestyles and consumption patterns similarity. The author measures the Globalization effect in Europe by exploring two variables: Employment in the Service Sector and involvement in world trade-increase of exports and imports. Countries with high percentage (75-80) of employment in the service sector and a fast growth of foreign trade fit best for the demanding conditions of Globalization. The 12 new EU members should adopt this strategy in order to accelerate their economicgrowth.
A “Fine Structure Constant” for Inertia  [PDF]
Amos Harpaz
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.34046
Abstract:

We try to find a physical source for the inertial force, which contradicts the acceleration of an object. We find that when an object is accelerated, its gravitational field curves, and the stress force created in this curved field acts on the object against the accelerating force, thus supplying part of the inertial force that contradicts the acceleration. We also find that this force includes a term which is similar to the fine structure constant used in quantum mechanics. As well, we find that this term equals unity for a black hole object. Further work is needed in order to find whether the complete inertial force can be found in this way. The experimental results that may prove this approach are still very limited.

The Gravitational Radiation Emitted by a System Consisting of a Point Particle in Close Orbit around a Schwarzschild Black Hole  [PDF]
Amos S. Kubeka
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310186
Abstract: We analytically model a relativistic problem consisting of a point-particle with mass m in close orbit around a stationary Schwarzschild black hole with mass M = 1 using the null-cone formalism when l = 2. We use the -function to model the matter density of the particle. To model the whole problem, we apply the second order differential equation obtained elsewhere for a dynamic thin matter shell around a Schwarzschild black hole. The only thing that changes on the equation is the quasi-normal mode parameter which now represent the orbital frequency of the particle. We compare our results with that of the standard 5.5 PN formalism and found that there is a direct proportionality factor that relates the two results, i.e. the two formalisms.
Erratum: The Gravitational Radiation Emitted by a System Consisting of a Point Particle in Close Orbit around a Schwarzschild Black Hole  [PDF]
Amos S. Kubeka
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.48150
Abstract:

We correct from the previous paper: the first, second and third order derivatives of the Bondi metric function J at the ISCO of the binary system consisting of a Schwarzschild black hole and a point particle. Previously, these derivatives where not correctly determined and that resulted in the incorrect determination of the emitted gravitational radiation at null infinity. The now correctly calculated gravitational radiation is now in full agreement with that obtained by the standard 5.5 PN formalism to about ninety eight percent. The small percentage difference observed is due to the slow convergence property of the PN formalism as compared to the null cone formalism, otherwise the results are basically the same.

Establishing landuse/cover change patterns over the last two decades and associated factors for change in semi arid and sub humid zones of Tanzania  [PDF]
Amos Enock Majule
Open Journal of Ecology (OJE) , 2013, DOI: 10.4236/oje.2013.36051
Abstract:

This study investigated landuse cover change patterns and established potential environmental and social factors that have contributed to changes in two zones namely sub humid and semi-arid found in southern highland and central parts of Tanzania respectively. The overall objective was to understand change patterns; the process evolves and clearly isolates various factors that have contributed to the changesover the last 20 years. A total of four villages,two in each zone were involved whereby historical land use cover changes were analysed using remote sensing techniques. To do so satellite imageries for1991 and 2011 and those of1986 and 2009 for sub humid and semi-arid zones respectively. Factors for changes were established through focus group discussions (FDGs) with a total of 80 participants (20 per village) and household (HH) interviews subjected to 10% of the total number of HH per village. Both woodlands and bush lands decreased in the expense of mixed farming in both sub humid and semi- arid zones to a maximum of 121% and 146.8% respectively. Wetland farming also increased particular in sub humid zone. In general, both environmental and social factors were found to have contributed to LUCC in various magnitudes in both zones. Such observed change on landuse will continue and it is recommended that there is a need to have in place and implement proper landuse plan also have capacity building programs on climate and land management issues for both livelihood and ecosystem sustainability need to in place.

Evidence of Increasing Regional Income Variation in the United States: 1969-2006  [PDF]
Orley M. Amos Jr.
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.55049
Abstract:

This paper investigates the inter-county variation of per capita personal income within US states from 1969 to 2006. It is a test of the growth pole cycles theory of spatial-temporal economic development that combines the theory of growth poles with the theory of long wave cycles. Standard OLS regression analysis is performed using data from the Bureau of Economic. Results indicate that regional income variation increased for the majority of states with no indication of a decrease or convergence of regional incomes.

The Gravitational Radiation Emitted by Two Quasi-Particles around a Schwarzschild Black Hole  [PDF]
Amos S. Kubeka
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.96072
Abstract: We model analytically a relativistic problem consisting of two quasi-particles each with mass m in close orbit around a static Schwarzschild black hole with mass M = 1 situated at the center of mass of the system. The angular momentum l of the system is taken to be 2. We model the mass density of the orbiting particles as a δ-function and we assume that there are no deformations. To model the system, we apply the second-order differential equation obtained elsewhere for a dynamic thin matter shell on a Schwarzschild background. As it is the case in this paper, the framework on which the equation was obtained is Bodi-Sachs. The only change in the equation is that now the quasi-normal mode parameter represents the particle’s orbital frequency from which we are able to analytically compute the gravitational radiation emitted by the system at null infinity. We note that in a real astrophysical scenario the dynamics of the particles paths will be very dynamic and complicated and that the analytical methods used here will have to be developed further to accommodate that.
An enigmatic satellite
William Amos
Genome Biology , 2011, DOI: 10.1186/gb-2011-12-4-110
Abstract: See research article: http://genomebiology.com/2011/12/4/R37 webciteSatellite DNA has always tended towards the enigmatic and the controversial. Originally named after 'satellite' bands that appeared when genomic DNA was separated by density gradient centrifugation, it was shown to comprise highly repeated DNA with unusually high or low GC content, hence its different buoyant densities. Early studies revealed unexpected patterns that came to be known as 'concerted evolution', where individual repeats within a tandem array appear to evolve cohesively rather than as independent units. A spectacular example occurs in whales, where a single 1.73-kb satellite sequence is present in about 100,000 copies in most species. However, in certain dolphins the overwhelming majority of repeats carry a 150-base deletion, a pattern that is clearly not the result of 100,000 independent deletion events [1]! In a recent paper in Genome Biology, McLaughlin and Chadwick [2] provide an exciting continuation of this story. They study a human 'macrosatellite', DXZ4, an X-linked 3-kb tandem repeat that might previously have been dismissed as repetitive junk. They show that it is anything but junk, having instead a remarkable range of properties that include being transcribed but probably not translated, being conserved across many primates and remaining active while almost every other gene around it is shut down on the inactivated X chromosome.Classical satellite DNA includes both highly repeated sequences whose function is largely unclear and gene families such as the ribosomal RNA genes (rDNA). However, the tandemly repeated format inspired derivative names coined for shorter motifs. Thus, when Jeffreys and colleagues [3] discovered a class of highly unstable tandem repeats capable of generating complicated, individual-specific banding patterns, they named them 'minisatellites', as the repeat unit was of the order of a few tens rather than thousands of bases long. The resulting technique,
Sexual selection does not influence minisatellite mutation rate
William Amos
BMC Evolutionary Biology , 2009, DOI: 10.1186/1471-2148-9-5
Abstract: I find that Moller and Cuervo's data set contains numerous errors that act somewhat to strengthen their key regression. More importantly, data from uncited papers fail to replicate their reported trend and one species in particular, Vireo olivaceus, is apparently deliberately omitted, yet its inclusion removes significance from the original correlation. Over the small number of cases were comparisons can be made, mutation rate estimates do not differ between species but do vary significantly depending on the laboratory/operator.There appears to be no clear relationship between minisatellite mutation rate and EPC rate in birds. The previously reported trend can be attributed to data transcription errors and unfortunate data selection. My analysis highlights the importance of total methodological transparency when conducting meta-analyses.M?ller and Cuervo recently published an analysis of literature-based data purporting to show a positive relationship between the rate of extra pair paternity (EPP), a surrogate measure of sexual selection, and minisatellite mutation rate, a possible indicator of the genome-wide mutation rate [1]. Their intriguing idea is that sexually selected species need to evolve fast and have been selected for elevated mutation rates to facilitate this. If true, this would indeed be an important finding. However, the regression on which their main conclusion is based looks weak. Moreover, the estimation of minisatellite mutation rates, as described, embraces a wide range of sources of error that together make it unlikely to be accurate enough to detect even medium to strong trends.M?ller and Cuervo estimate minisatellite mutation rate using classical DNA fingerprint data from confirmed mother-father-offspring trios [1]. When the fingerprint profiles of a confirmed family are examined, bands are occasionally seen in an offspring that occur in neither parent [2]. Such bands are expected because the high mutation rate of minisatellites [3] combined
