Disability, Social Policy and the Burden of Disease: Creating an “Assertive” Community Mental Health System in New York  [PDF]
Mark B. Borg, Jr.
Psychology (PSYCH) , 2010, DOI: 10.4236/psych.2010.12018
Abstract: One conclusion of the decade-long epidemiological Global Burden of Disease Project is that five of the top 10 disease “burdens” the world will face by 2020 will be related to mental disabilities. Therefore, developing social policy and community responses to the ways that people with mental disabilities are treated is becoming an important focus for community practitioners, political activists and legislators. The author explores some of the dynamics of our culture’s approach to dealing with difference, especially when manifested in disenfranchized individuals. He discusses a community development project created by a New York City advocacy and social policy organization following the 1999 murder of a woman by an individual whose mental health disability was never treated. Parallels are drawn between the civil rights and community mental health movements, which created a precedent for the 1990 Americans with Disabilities Act. Also examined are the ways in which community mental health systems manifest social policy that alternately resists, repeats and colludes with power operations. The unexamined assumptions that drive this dynamic are examined as ableism or disability oppression.
Parkinson’s Disease—Apoptosis and Dopamine Oxidation  [PDF]
James David Adams Jr.
Open Journal of Apoptosis (OJApo) , 2012, DOI: 10.4236/ojapo.2012.11001
Abstract: Tyrosine hydroxylase, monoamine oxidase and aldehyde dehydrogenase all form oxygen radicals as part of their mechanisms of action. These oxygen radicals damage dopaminergic neurons in the substantianigra of the midbrain and cause them to die by a process of necrosis or apoptosis. Oxygen radicals quickly abstract hydrogen from DNA forming DNA radicals and causing DNA fragmentation, activation of DNA protective mechanisms, NAD depletion and cell death. Tyrosine hydroxylase is present in all dopaminergic neurons, is involved in the synthesis of dopamine and forms oxygen radicals in a redox mechanism involving its cofactor, tetrahydrobiopterin. Levodopa is used therapeutically in Parkinson’s disease patients since it is a precursor for dopamine, an inhibitor of tyrosine hydroxylase, and prolongs pa-tient’s lives. Monoamine oxidase converts dopamine into 3,4-dihydroxyphenylacetaldehyde and forms oxygen radi-cals.Aldehyde dehydrogenase oxidizes the aldehyde and forms oxygen radicals and 3,4-dihydroxyphenylacetic acid. The treatment of Parkinson’s disease should involveinhibitors of oxygen radical formation in dopaminergic neurons and neuroprotective agents that stimulate DNA repair and prevent cell death.
A General Theorem on the Conditional Convergence of Trigonometric Series  [PDF]
Edgar A. Cohen Jr.
Open Journal of Discrete Mathematics (OJDM) , 2013, DOI: 10.4236/ojdm.2013.31003
Abstract: The purpose of this paper is to establish, paralleling a well-known result for definite integrals, the conditional convergence of a family of trigonometric sine series. The fundamental idea is to group appropriately the terms of the series in order to show absolute divergence of the series, given the well-established result that the series as it stands is convergent.
Dark Particles Answer Dark Energy  [PDF]
John L. Haller Jr.
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.47A1010
Abstract:

This paper argues that a hypothetical “dark” particle (a black hole with the reduced Planck mass and arbitrary temperature) gives a simple explanation to the open question of dark energy and has a relic density of only 17% more than the commonly accepted value. By considering an additional near-horizon boundary of the black hole, set by its quantum length, the black hole can obtain an arbitrary temperature. Black-body radiation is still present and fits as the source of the Universe’s missing energy. Support for this hypothesis is offered by showing that a stationary solution to the black hole’s length scale is the same if derived from a quantum analysis in continuous time, a quantum analysis in discrete time, or a general relativistic analysis.

Entropy Rate of Thermal Diffusion  [PDF]
John L. Haller Jr.
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.410167
Abstract:

The thermal diffusion of a free particle is a random process and generates entropy at a rate equal to twice the particle’s temperature, \"\" (in natural units of information per second). The rate is calculated using a Gaussian process with a variance of \"\" which is a combination of quantum and classical diffusion. The solution to the quantum diffusion of a free particle is derived from the equation for kinetic energy and its associated imaginary diffusion constant; a real diffusion constant (representing classical diffusion) is shown to be \"\" . We find the entropy of the initial state is one natural unit, which is the same amount of entropy the process generates after the de-coherence time, \"\".

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.

Measuring a Quantum System’s Classical Information  [PDF]
John L. Haller Jr.
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.51002
Abstract:

In the governing thought, I find an equivalence between the classical information in a quantum system and the integral of that system’s energy and time, specifically \"\", in natural units. I solve this relationship in four ways: the first approach starts with the Schrodinger Equation and applies the Minkowski transformation; the second uses the Canonical commutation relation; the third through Gabor’s analysis of the time-frequency plane and Heisenberg’s uncertainty principle; and lastly by quantizing Brownian motion within the Bernoulli process and applying the Gaussian channel capacity. In support I give two examples of quantum systems that follow the governing thought: namely the Gaussian wave packet and the electron spin. I conclude with comments on the discretization of space and the information content of a degree of freedom.

Pedagogy and Cultural Manifestations in the Weaving Practices of the Yakan Tribe  [PDF]
Espiridion D. Atilano Jr.
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.28011
Abstract:

The Yakan weaving practices were integral to the personal and cultural life of the tribe. This study sought to describe how the teaching and learning happen in the Yakan weaving practices as well as determine the significance of weaving in the economic, social and environmental aspects of the Yakans’ way of life. Anchored on the Social Cognitive Theory (SCT) of Albert Bandura, learning occurs through the observation and imitation of the innate person (learner) of the modeled behavior (weaving) in a learning environment (Socio-cultural norms in the Yakan community.) The study utilized a qualitative and descriptive design. Pertinent data were obtained through Focus Group Discussion (FGD), Key Informant Interview (KII) and Fieldwork Observation Checklist (FOC). The respondents of the FGD were the weavers of the two Yakan communities in the cities of Zamboanga and Lamitan. The communities also served as the subject of the FOC. Three experts on Yakan textile and culture were probed in the KII. Purposive Sampling Technique was used to select the respondents of the FGD and the Snowball method to identify the informants for the KII. Results show that the Yakan weaving practices are transferred from one generation to another by the mothers to their daughters. The pedagogy could either be structured, through demonstration and modeling by the teacher or informal through observation and imitation of the learner. Moreover, the interplay of culture is evident in the Yakan weaving through the economic and social practices as well as the adaptation in the environmental changes of the tribe. Lastly, there is a need to enhance the teaching and learning of weaving to accommodate more learners and to strike a balance between the preservation of the tribe’s culture and the profitability of the weaving textile business.

The Twins Clock Paradox History and Perspectives  [PDF]
Robert L. Shuler Jr.
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.512108
Abstract:

The twins or clock paradox has been a subject of lively discussion and occasional disagreement among both relativists and the public for over 100 years, and continues to attract physicists who write papers giving new analyses or defending old ones, even though many physicists now consider the matter only of educational interest. This paper investigates the number of papers, which is increasing, and trends in explanations, some of which are now targeted at professional physicists and other of which are targeted at optical or radar visualization rather than problem solving. Observations of students indicate that the latest techniques help but only somewhat. An analysis is made of 21 previous treatments appearing in the education related American Journal of Physics, Einstein’s discussions and several other pedagogical papers. A new memory aid for simultaneity transformation is given that puts it on a par with “time dilation” and “length contraction” for quick and easy problem visualization. The point of view of a trailing twin is introduced to show how simultaneity changes account for missing time in the turnaround. Length contraction is treated on equal footing with time dilation, and Swann’s insight into clocks is extended to lengths. Treatments using the conventionality of simultaneity are seen as equivalent to choice of co-moving frames. Responses to difficult questions are suggested which avoid being dismissive, and engage students’ critical thinking.

A Solution of a Problem of I. P. Natanson Concerning the Decomposition of an Interval into Disjoint Perfect Sets  [PDF]
Edgar A. Cohen Jr.
Advances in Pure Mathematics (APM) , 2014, DOI: 10.4236/apm.2014.45024
Abstract:

In a previous paper published in this journal, it was demonstrated that any bounded, closed interval of the real line can, except for a set of Lebesgue measure 0, be expressed as a union of c pairwise disjoint perfect sets, where c is the cardinality of the continuum. It turns out that the methodology presented there cannot be used to show that such an interval is actually decomposable into c nonoverlapping perfect sets without the exception of a set of Lebesgue measure 0. We shall show, utilizing a Hilbert-type space-filling curve, that such a decomposition is possible. Furthermore, we prove that, in fact, any interval, bounded or not, can be so expressed.
