Rural Adolescent Residential Treatment Facilities as Centers of Clinical Support and Excellence  [PDF]
Kenneth M. Coll, Robin Haas
Advances in Applied Sociology (AASoci) , 2013, DOI: 10.4236/aasoci.2013.32013
Abstract: In rural western states (e.g., Wyoming, Idaho, Montana, Utah) that are large geographically and small in population, it is unrealistic to expect to have comprehensive mental health and substance abuse professional support in most rural communities. One viable idea is for mature and distinguished treatment facilities in those geographic areas to expand their delivery system.
Exploring Irish Multigenerational Trauma and Its’ Healing: Lessons from the Oglala Lakota (Sioux)  [PDF]
Kenneth M. Coll, Brenda Freeman, Paul Robertson, Eileen Iron Cloud, Ethleen Iron Cloud Two Dog, Rick Two Dogs
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.22013
Abstract: This exploratory article reviewed the professional literature related to the construct of multigenerational trauma and the importance of cultural identity and practices as healing and protective/resilience factors against such trauma. It also posited that the Irish and the Oglala Lakota (Sioux) of the North American Northern Plains have commonalities; one commonality perhaps being multigenerational trauma (also called historical loss, transgenerational trauma/shame). Emerging evidence about treatment of multiagenerational trauma with the Lakota through implementing their cultural practices and cultural renewal in rural settings are also discussed. Finally, this investigation describes results from a focus group experience with 12 Irish counselors from rural Southeastern Ireland that explored resiliency related to multi- generational trauma using genograms to describe and compare traumatic and resiliency patterns. {Note: This exploratory approach does not include Irish Diaspora (e.g., Irish-Americans, Irish-Australians, and Irish-Canadians)}. It is hoped that based on the results of this approach, further investigations can occur with these populations.

Atmospheric neutrino oscillations with the MACRO detector
M. Giorgini,for the MACRO Coll
Physics , 2002,
Abstract: After a short overview of the MACRO detector, located at the Gran Sasso Laboratory, I shall present and discuss the results on atmospheric muon neutrino oscillations, concerning low ( ~ 4 GeV) and high ( ~ 50 GeV) energy data. Using the Multiple Coulomb Scattering of muons inside the lower part of the detector, estimates of the neutrino energy were made event by event for the high energy sample. The data on angular distributions, absolute flux and L/E_nu distribution favor nu_mu <--> nu_tau oscillations with maximal mixing and Delta m^2=2.5 x 10^-3 eV^2.
Multi-Messenger Astrophysics with IceCube
M. Ribordy,for the IceCube coll
Physics , 2011,
Abstract: The cubic kilometer IceCube neutrino telescope now operating at the South Pole in a near complete configuration observes the neutrino sky with an unprecedented sensitivity to galactic and extra-galactic cosmic ray accelerators. Within the multi-messenger framework, IceCube offers unique capabilities to correlate and contrast the neutrino sky with the gamma-ray sky and ultra high energy cosmic rays and complements other indirect and direct dark matter search programs. We review here the status of the experiment and recent selected results. A discussion of the implications of the observations will be followed by the prospects of future developments, substantially extending the reach of the observatory at extremely high energies, in the GZK region and at low energies enhancing capabilities to probe dark matter and cosmic ray sources in the southern sky.
Structural Analysis and Mutant Growth Properties Reveal Distinctive Enzymatic and Cellular Roles for the Three Major L-Alanine Transaminases of Escherichia coli
Esther Pe?a-Soler, Francisco J. Fernandez, Miguel López-Estepa, Fernando Garces, Andrew J. Richardson, Juan F. Quintana, Kenneth E. Rudd, Miquel Coll, M. Cristina Vega
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0102139
Abstract: In order to maintain proper cellular function, the metabolism of the bacterial microbiota presents several mechanisms oriented to keep a correctly balanced amino acid pool. Central components of these mechanisms are enzymes with alanine transaminase activity, pyridoxal 5′-phosphate-dependent enzymes that interconvert alanine and pyruvate, thereby allowing the precise control of alanine and glutamate concentrations, two of the most abundant amino acids in the cellular amino acid pool. Here we report the 2.11-? crystal structure of full-length AlaA from the model organism Escherichia coli, a major bacterial alanine aminotransferase, and compare its overall structure and active site composition with detailed atomic models of two other bacterial enzymes capable of catalyzing this reaction in vivo, AlaC and valine-pyruvate aminotransferase (AvtA). Apart from a narrow entry channel to the active site, a feature of this new crystal structure is the role of an active site loop that closes in upon binding of substrate-mimicking molecules, and which has only been previously reported in a plant enzyme. Comparison of the available structures indicates that beyond superficial differences, alanine aminotransferases of diverse phylogenetic origins share a universal reaction mechanism that depends on an array of highly conserved amino acid residues and is similarly regulated by various unrelated motifs. Despite this unifying mechanism and regulation, growth competition experiments demonstrate that AlaA, AlaC and AvtA are not freely exchangeable in vivo, suggesting that their functional repertoire is not completely redundant thus providing an explanation for their independent evolutionary conservation.
Davidson y la crítica al empirismo
Jesús Coll Mármol
Límite , 2008,
Abstract: Este artículo examina la crítica que Donald Davidson realiza a una de las doctrinas filosóficas más ampliamente aceptadas: el empirismo. El empirismo mantiene desde distintas perspectivas que la apelación a la experiencia es crucial para explicar alguno de nuestros más importantes conceptos y logros epistemológicos. Como se mostrará, la crítica de Davidson al empirismo es de gran calado, pues no sólo se ala las incoherencias internas que algunas posiciones empiristas pueden plantear, sino los problemas que cualquier propuesta empirista está condenada a suscribir. Así mantiene que la experiencia, incluso en sus presentaciones más prometedoras, no puede realizar las tareas que los filósofos empiristas le encomiendan. Se finalizará argumentando que algunos intentos empiristas de evitar las críticas de Davidson fallan al reconocer el verdadero alcance de las mismas.
Comparison of Different Waste Management Technologies and Climate Change Effect—Jordan  [PDF]
Mohammad Aljaradin, Kenneth M. Persson
American Journal of Climate Change (AJCC) , 2012, DOI: 10.4236/ajcc.2012.12006
Abstract: Solid waste management (SWM) strategies offer huge potentials to contribute to climate change mitigation. To assess the potentials of SWM to contribute to greenhouse gas (GHG) reduction and resource recovery, available technologies and strategies have to be analyzed. In this work, a SWM-GHG calculator was used to compare different potential strategies for waste management considering economic situation, environmental and social awareness in Jordan. Four scenarios representing the current and suggested technologies (increase recovery, biological treatment, and advance biological treatment) were studied. The results showed that a vast reduction of GHG emission of about 63,175 tons CO2-eq/year was observed in the fourth scenario where all the organic waste was recovered. Moreover, this scenario increased the net caloric values in reused waste from 8.4 to 9.6 MJ/kg. The results suggest that the SWM-GHG calculator can offer sufficiently accurate approximation of the GHG impacts of different suggested strategies in the country and can serve as an important contribution to decision makers.
Menos es más: davidson y el extravío del escéptico
Coll Mármol,Jesús A.;
An??lisis filos?3fico , 2007,
Abstract: this article discusses what is the best way of understanding the antisceptical consequences of davidson's approach to thought and language. it rejects that from such approach follows, with or without the help of an omniscient interpreter, a refutation of the sceptical position. it defends that davidson's philosophy should be understood as a theoretical diagnosis of scepticism where davidson's antirepresentacionalism plays a fundamental role. from this reading it would not follow a definitive refutation of the sceptical position, but it would be shown that this position is not compulsory by defending that scepticism depends on distinctive philosophical views that are far from obvious.
Em busca de metodologias investigativas com as crian?as e suas culturas
Delgado, Ana Cristina Coll;Müller, Fernanda;
Cadernos de Pesquisa , 2005, DOI: 10.1590/S0100-15742005000200009
Abstract: this article features reflections on investigative methodologies with children and their cultures from the point of view of sociology of childhood. this theoretical field considers children as social actors that build fight strategies by means of their peer cultures. the brazilian academic production on children and their cultures does not have yet a tradition of studies on the voices of children themselves. this issue has led to the organization of this text in three sections. in the first section we think of the absence of children in brazilian researches and the influences of an androcentric science emerging with modernity. in the second section we present the ethnography of childhoods as a possibility of contact and acceptance of adults by groups of children in order to understand their peer cultures. in the third section we raise some ideas concerning the traits of children cultures as a theoretical basis for the construction of other manners of conducting research, which connect science and aesthetics, reason and emotion, fantasy and reality.
