The thesis examines homeowners associations as a part of the large-scale housing reform, implemented in Russia since 2005. The reform transferred housing management from the public sector to the private sector and to the citizens responsibility. The reform is a continuation to the privatisation of the housing stock that was started in Russia in the beginning of the 1990s, aiming to build a market-oriented housing sector in the country. The reform makes a fundamental change to the Soviet system, in which ownership along with management and maintenance of housing were monopolised by the state. Homeowners are now responsible for the management of the common areas in privatised houses, which is often realised by establishing a homeowners association. Homeowners associations are examined by using the so-called common-pool resource regime approach, with the main question being the ways in which taking care of common property collectively succeeds in practice. The study is based on interview data of St. Petersburg s homeowners associations. Using the common-pool resource theory the study demonstrates why implementation of the housing reform has not succeeded as expected. Certain elements that characterise a successful common-pool resource regime do not fulfill sufficiently in St. Petersburg s homeowners associations. Firstly, free-riding, that is, withdrawal from the association s joint decision-making and not making the housing payments is common, as effective sanctions to prevent it are missing in the legislation. That is, eviction or expelling a non-paying member from the association is not possible. Secondly, ownership of the land plot and common areas of the house, such as basements and attics, are often disputed between the associations and authorities. In the Soviet era, these common areas were public property along with the apartments, but in privatised houses they should, according to the legislation, belong to the associations property. Thirdly, solution of disputes between the associations and authorities and within the associations is difficult, as the court system tends to be bureaucratic and inefficient. In addition to the common-pool resource approach, the study also examines how social capital contributes to the associations effectiveness and democratic governance. The study finds that although homeowners associations have increased cooperation and tightened social relations between neighbours, social capital has not been able to prevent free-riding. The study shows that unlike it is often claimed, the so-called Soviet mentality , that is, residents passiveness and unwillingness to participate, is not the most important obstacle to the reform. Instead, the reform is impeded most of all by imperfect institutional arrangements and local authorities that prevent the associations from working as independent, self-governing associations.

We study the equilibrium properties of the nearest-neighbor Ising antiferromagnet on a triangular lattice in the presence of a staggered field conjugate to one of the degenerate ground states. Using a mapping of the ground states of the model without the staggered field to dimer coverings on the dual lattice, we classify the ground states into sectors specified by the number of "strings." We show that the effect of the staggered field is to generate long-range interactions between strings. In the limiting case of the antiferromagnetic coupling constant J becoming infinitely large, we prove the existence of a phase transition in this system and obtain a finite lower bound for the transition temperature. For finite J, we study the equilibrium properties of the system using Monte Carlo simulations with three different dynamics. We find that in all the three cases, equilibration times for low-field values increase rapidly with system size at low temperatures. Due to this difficulty in equilibrating sufficiently large systems at low temperatures, our finite-size scaling analysis of the numerical results does not permit a definite conclusion about the existence of st phase transition for finite values of J. A surprising feature in the system is the fact that unlike usual glassy systems; a zero-temperature quench almost always leads to the ground state, while a slow cooling does not.

Guanylyl cyclase C (GC-C) is expressed in intestinal epithelial cells and serves as the receptor for bacterial heat-stable enterotoxin (ST) peptides and the guanylin family of gastrointestinal hormones. Activation of GC-C elevates intracellular cGMP, which modulates intestinal fluid-ion homeostasis and differentiation of enterocytes along the crypt-villus axis. GC-C activity can regulate colonic cell proliferation by inducing cell cycle arrest, and mice lacking GC-C display increased cell proliferation in colonic crypts. Activation of GC-C by administration of ST to wild type, but not Gucy2c(-/-), mice resulted in a reduction in carcinogen-induced aberrant crypt foci formation. In p53-deficient human colorectal carcinoma cells, ST led to a transcriptional up-regulation of p21, the cell cycle inhibitor, via activation of the cGMP-responsive kinase PKGII and p38 MAPK. Prolonged treatment of human colonic carcinoma cells with ST led to nuclear accumulation of p21, resulting in cellular senescence and reduced tumorigenic potential. Our results, therefore, identify downstream effectors for GC-C that contribute to regulating intestinal cell proliferation. Thus, genomic responses to a bacterial toxin can influence intestinal neoplasia and senescence.

Resumen: En el mundo educativo actual las corrientes pedagógicas se han visto sumidas en lo que podríamos denominar «el olvido del maestro», pues este se torna ininteligible cuando no hay una verdad que comunicar. La educación se convierte entonces en una construcción por parte del alumno de un mundo de significados subjetivos y cambiantes, que el maestro solo estimula. Frente a esto encontramos la enseñanza de santo Tomás de Aquino, Doctor Humanitatis, quien nos recuerda que las palabras del maestro, verba doctoris, son comunicativas de la verdad ya conocida. Solo fundados en este principio es posible devolver a la palabra educativa la fecundidad que le corresponde, tan necesaria para el perfeccionamiento del hombre y de la sociedad. En este artículo se presenta una reflexión acerca del lugar que ocupa la palabra verdadera en la educación de los hombres, mostrando cómo la vida humana no tiende solo a expresarse en la palabra, sino a ser fecunda en la palabra educativa.

Resumen: Durante los últimos años se ha podido notar de parte de los especialistas del pensamiento de Santo Tomás un interés creciente en sus comentarios bíblicos. Este ensayo se inscribe en este movimiento. El autor intenta llamar la atención a la teología del Espíritu Santo tal como esta se presenta no solo en la Suma de Teología sino también en otros escritos del Doctor Común. Después de presentar un resumen de las cuestiones 27 - 36, 37 y 38 de la primera parte de la ST, muestra la sorprendente riqueza de los tratados sobre el Espíritu Santo en la Suma contra los Gentiles, IV. cc. 15 a 26. El rol central e importantísimo del Espíritu Santo en la vida de la Iglesia es estudiado en un análisis del comentario de Tomás a las Cartas de san Pablo, en particular a la Carta a los Romanos y del Evangelio según San Juan. Para subrayar la dignidad de la devoción al Espíritu Santo, el autor ha añadido una sección sobre los Dones del Espíritu Santo, en particular en su relación con las virtudes teologales y morales, y con los Carismas. Unas páginas sobre la Ley Nueva como la gracia del Espíritu Santo concluyen este estudio.

Resumen: En ocasión de la autobiografía de Robert Spaemann aparecida en 2012, este trabajo examina la lectura que Spaemann hace de la teleología en la doctrina de Santo Tomás de Aquino, especialmente en su obra Natürliche Ziele (2005) que prosigue la versión de 1981. En la primera parte, se estudia la historia de la teleología en el pensamiento filosófico y científico expuesta en «Fines naturales». La finalidad intrínseca en la naturaleza de los seres es conocida con profundidad creciente gracias a Platón, Aristteles, al estoicismo y a la tradición cristiana. Estos aportes se integran en una estructura teleológica unitaria en el Aquinate. Después acontece una «inversión» de la teleología centrada en la conservación del propio ser y una consideración de los fines como algo externo a la realidad. Con la teoría evolucionista surge la teleonomía que se limita a las reglas del dinamismo, suprimiendo el fin. Con todo, los científicos no logran eliminar los términos «con el fin de» o «para» en su lenguaje. Eso permite proceder a un redescubrimiento de los fines naturales. En la segunda parte, se ve cómo Tomás de Aquino lleva el conocimiento de la finalidad más allá de Aristteles, porque ella remite a una inteligencia creadora. La teleología implica una teología, aunque no queda del todo claro si es la teología filosófica o la cristiana. Spaemann tiene un planteo ontológico de tipo persuasivo, pero en algunos momentos siente dificultad para superar en el plano teorético a quien se limita a una teleonomía.

Resumen: De acuerdo a la mente de Santo Tomás de Aquino, la potencia de conocimiento sensible que se denomina «cogitativa » es susceptible de una doble consideración. Por un lado, es la estimativa animal y, como tal, aprehende su mismo objeto formal quod, esto es, las intenciones de beneficio o perjuicio a nivel sensible. Pero a causa de su particular modo de operar, esas intenciones no son conocidas por ella solamente en orden a la conservación del individuo humano o de la especie a la que él pertenece. El reconocimiento de una doble dimensión de la cogitativa est en Santo Tomás justificado por la particular relación que existe entre ella y la razón universal. Por un lado, la cogitativa no es una facultad distinta de la estimativa natural. Por esto, ella aprehende las intenciones necesarias para la perfección de la vida sensitiva humana. Por otro lado, la razón ejerce sobre la cogitativa un influjo particular que la hace operar a su modo, esto es, de manera discursiva. Este carácter móvil en la aprehensión de la cogitativa permite la conformación de una experiencia a nivel sensible, en virtud de la cual su objeto formal se ve ampliado. Esto resulta aún más razonable si se tiene en cuenta que el conocimiento sensorial del hombre prepara el intelectual. De esta manera, la cogitativa no aprehende simplemente al individuo como beneficioso o perjudicial para la subsistencia del cognoscente, sino como sujeto de una cierta naturaleza.

Resumen: La idea de que los compositores barrocos planificaban su obra en función de las reglas de la retórica es común en los manuales especializados. No obstante, Brian Vickers descarta la posibilidad de su utilización como medio analítico en la música. Rubén López Cano considera la retórica como un metalenguaje y abre la posibilidad de aplicar el sistema retórico, propio del sistema lingüístico, a otro no verbal. En el presente trabajo pretendo demostrar cómo el aparato teórico de la retórica del barroco subyace en la composición musical de este período. Con el fin de ejemplificar esto, utilizo el análisis de una sección de la Pasión según San Mateo de J. S. Bach.

Resumen: En el pensamiento de Santo Tomás de Aquino, la Filosofía Moral y la Teología Moral tienen al bien como concepto central, es decir, el ser en cuanto apetecible y en cuanto fin de la tendencia o apetito. Lo anterior es debido a que lo bueno expresa el ser en cuanto se relaciona con el apetito y de este modo señala la capacidad del ser para mover la voluntad o una tendencia cualquiera hacia su fin. Es por esto que Santo Tomás sostiene con Aristteles que el bien coincide con la noción de fin. Y es por la importancia de estos principios y por su repercusión en la moral y sobretodo en la explicación de la libertad moral, que este breve trabajo consiste en una profundización en las relaciones entre el bien, el fin y la naturaleza y algunas de sus aplicaciones a lo que se conoce como tendencia natural o apetito natural y la tendencia libre que se refiere a la voluntad sobre todo a la voluntad de la persona humana. No se trata de un intento por presentar todas las conclusiones que de estos principios se siguen, lo cual correspondería a la Filosofía o a la Teología Moral, sino más bien de una profundización en los principios metafísicos, para asentar los cimientos del orden moral.

Resumen: En este trabajo seguimos la presentación de la materia, la forma y la privación realizada por Santo Tomás de Aquino en los dos primeros capítulos del De principiis naturae. Identificados como los principios de la naturaleza, son la clave para entender las definiciones de generación de las que nos provee el Aquinate. Él entiende la generación, protagonista de los cambios del mundo material, en sus principios, descubiertos en sus relaciones acto-potenciales. Completa esta presentación la distinción entre las substancias y los accidentes y sus consecuencias en el campo de los cambios de los cuerpos. Luego, Santo Tomás extiende los análisis de la privación y de la materia. La privación, entonces, es bien distinguida de la negación, porque el Aquinate muestra su dimensión potencial. La materia, por otro lado, se descubre en su pluralidad de sentidos y nos permite hablar de una participación de la materia, a partir de la principalísima materia ex qua o primera. Por último, tomamos nota de las fuentes secundarias de este texto, revisando pasajes de San Agustn y Averroes.

Resumen: Es un hecho que Dios ha impreso de un modo necesario e indefectible la dirección hacia su fin a las creaturas materiales y a las creaturas espirituales incluido el caso concreto del hombre. Pero también es un hecho que en el mundo corpóreo, la persona humana cuenta con la libertad de los medios para alcanzar dicho fin. En esto se distingue el hombre de los animales irracionales, en que la naturaleza espiritual y libre ha de ser encauzada en su actividad por una ley específicamente distinta a la del mundo irracional, que a la vez de conducirla eficazmente hacia su fin, sea compatible con la libertad. Dada la relevancia de este tema para la comprensión del problema moral del hombre, el objeto de este trabajo es profundizar en la naturaleza del acto libre y por ende en los principios que fundamentan la libertad en el pensamiento de Santo Tomás de Aquino quien sin lugar a duda ha logrado una gran profundidad en el análisis del acto humano.

Executive Summary: This study describes the socio-economic characteristics of the U.S. Caribbean trap fishery that encompasses the Commonwealth of Puerto Rico and Territory of the U.S. Virgin Islands. In-person interviews were administered to one hundred randomly selected trap fishermen, constituting nearly 25% of the estimated population. The sample was stratified by geographic area and trap tier. The number of traps owned or fished to qualify for a given tier varied by island. In Puerto Rico, tier I consisted of fishermen who had between 1-40 fish traps, tier II was made up of fishermen who possessed between 41 and 100 fish traps, and tier III consisted of fishermen who held in excess of 100 fish traps. In St. Thomas and St. John, tier I was composed of fishermen who held between 1 and 50 fish traps, tier II consisted of fishermen who had between 51-150 fish traps and tier III was made up of fishermen who had in excess of 150 fish traps. Lastly, in St. Croix, tier I was made up of fishermen who had less than 20 fish traps and tier II consisted of fishermen who had 20 or more fish traps. The survey elicited information on household demographics, annual catch and revenue, trap usage, capital investment on vessels and equipment, fixed and variable costs, behavioral response to a hypothetical trap reduction program and the spatial distribution of traps. The study found that 79% of the sampled population was 40 years or older. The typical Crucian trap fisherman was older than their Puerto Rican and St. Thomian and St. Johnian counterparts. Crucian fishermen’s average age was 57 years whereas Puerto Rican fishermen’s average age was 51 years, and St. Thomian and St. Johnian fishermen’s average age was 48 years. As a group, St. Thomian and St. Johnian fishermen had 25 years of fishing experience, and Puerto Rican and Crucian fishermen had 30, and 29 years, respectively. Overall, 90% of the households had at least one dependent. The average number of dependents across islands was even, ranging between 2.8 in the district of St. Thomas and St. John and 3.4 in the district of St. Croix. The percentage utilization of catch for personal or family use was relatively low. Regionally, percentage use of catch for personal or family uses ranged from 2.5% in St. Croix to 3.8% in the St. Thomas and St. John. About 47% of the respondents had a high school degree. The majority of the respondents were highly dependent on commercial fishing for their household income. In St. Croix, commercial fishing made up 83% of the fishermen’s total household income, whereas in St. Thomas and St. John and Puerto Rico it contributed 74% and 68%, respectively. The contribution of fish traps to commercial fishing income ranged from 51% in the lowest trap tier in St. Thomas and St. John to 99% in the highest trap tier in St. Croix. On an island basis, the contribution of fish traps to fishing income was 75% in St. Croix, 61% in St. Thomas and St. John, and 59% in Puerto Rico. The value of fully rigged vessels ranged from $400 to $250,000. Over half of the fleet was worth $10,000 or less. The St. Thomas and St. John fleet reported the highest mean value, averaging $58,518. The Crucian and Puerto Rican fleets were considerably less valuable, averaging $19,831 and $8,652, respectively. The length of the vessels ranged from 14 to 40 feet. Fifty-nine percent of the sampled vessels were at least 23 feet in length. The average length of the St. Thomas and St. John fleet was 28 feet, whereas the fleets based in St. Croix and Puerto Rico averaged 21 feet. The engine’s propulsion ranged from 8 to 400 horsepower (hp). The mean engine power was 208 hp in St. Thomas and St. John, 108 hp in St. Croix, and 77 hp in Puerto Rico. Mechanical trap haulers and depth recorders were the most commonly used on-board equipment. About 55% of the sampled population reported owning mechanical trap haulers. In St. Thomas and St. John, 100% of the respondents had trap haulers compared to 52% in Puerto Rico and 20% in St. Croix. Forty-seven percent of the fishermen surveyed stated having depth recorders. Depth recorders were most common in the St. Thomas and St. John fleet (80%) and least common in the Puerto Rican fleet (37%). The limited presence of emergency position indication radio beacons (EPIRBS) and radar was the norm among the fish trap fleet. Only 8% of the respondents had EPIRBS and only 1% had radar. Interviewees stated that they fished between 1 and 350 fish traps. Puerto Rican respondents fished on average 39 fish traps, in contrast to St. Thomian and St. Johnian and Crucian respondents, who fished 94 and 27 fish traps, respectively. On average, Puerto Rican respondents fished 11 lobster traps, and St. Thomian and St. Johnian respondents fished 46 lobster traps. None of the Crucian respondents fished lobster traps. The number of fish traps built or purchased ranged between 0 and 175, and the number of lobster traps built or bought ranged between 0 and 200. Puerto Rican fishermen on average built or purchased 30 fish traps and 14 lobster traps, and St. Thomian and St. Johnian fishermen built or bought 30 fish traps and 11 lobster traps. Crucian fishermen built or bought 25 fish traps and no lobster traps. As a group, fish trap average life ranged between 1.3 and 5 years, and lobster traps lasted slightly longer, between 1.5 and 6 years. The study found that the chevron or arrowhead style was the most common trap design. Puerto Rican fishermen owned an average of 20 arrowhead traps. St. Thomian and St. Johnian and Crucian fishermen owned an average of 44 and 15 arrowhead fish traps, respectively. The second most popular trap design was the square trap style. Puerto Rican fishermen had an average of 9 square traps, whereas St. Thomian and St. Johnian fishermen had 33 traps and Crucian fishermen had 2 traps. Antillean Z (or S) -traps, rectangular and star traps were also used. Although Z (or S) -traps are considered the most productive trap design, fishermen prefer the smaller-sized arrowhead and square traps because they are easier and less expensive to build, and larger numbers of them can be safely deployed. The cost of a fish trap, complete with rope and buoys, varied significantly due to the wide range of construction materials utilized. On average, arrowhead traps commanded $94 in Puerto Rico, $251 in St. Thomas and St. John, and $119 in St. Croix. The number of trips per week ranged between 1 and 6. However, 72% of the respondents mentioned that they took two trips per week. On average, Puerto Rican fishermen took 2.1 trips per week, St. Thomian and St. Johnian fishermen took 1.4 trips per week, and Crucian fishermen took 2.5 trips per week. Most fishing trips started at dawn and finished early in the afternoon. Over 82% of the trips lasted 8 hours or less. On average, Puerto Rican fishermen hauled 27 fish traps per trip whereas St. Thomian and St. Johnian fishermen and Crucian fishermen hauled 68 and 26 fish traps per trip, respectively. The number of traps per string and soak time varied considerably across islands. In St. Croix, 84% of the respondents had a single trap per line, whereas in St. Thomas and St. John only 10% of the respondents had a single trap per line. Approximately, 43% of Puerto Rican fishermen used a single trap line. St. Thomian and St. Johnian fishermen soaked their traps for 6.9 days while Puerto Rican and Crucian fishermen soaked their traps for 5.7 and 3.6 days, respectively. The heterogeneity of the industry was also evidenced by the various economic surpluses generated. The survey illustrated that higher gross revenues did not necessarily translate into higher net revenues. Our analysis also showed that, on average, vessels in the trap fishery were able to cover their cash outlays, resulting in positive vessel income (i.e., financial profits). In Puerto Rico, annual financial profits ranged from $4,760 in the lowest trap tier to $32,467 in the highest tier, whereas in St. Thomas and St. John annual financial profits ranged from $3,744 in the lowest tier to $13,652 in the highest tier. In St. Croix, annual financial profits ranged between $9,229 and $15,781. The survey also showed that economic profits varied significantly across tiers. Economic profits measure residual income after deducting the remuneration required to keep the various factors of production in their existing employment. In Puerto Rico, annual economic profits ranged from ($9,339) in the lowest trap tier to $ 8,711 in the highest trap tier. In St. Thomas and St. John, annual economic profits ranged from ($7,920) in the highest tier to ($18,486) in the second highest tier. In St. Croix, annual economic profits ranged between ($7,453) to $10,674. The presence of positive financial profits and negative economic profits suggests that higher economic returns could be earned from a societal perspective by redirecting some of these scarce capital and human resources elsewhere in the economy. Furthermore, the presence of negative economic earnings is evidence that the fishery is overcapitalized and that steps need to be taken to ensure the long-run economic viability of the industry. The presence of positive financial returns provides managers with a window of opportunity to adopt policies that will strengthen the biological and economic performance of the fishery while minimizing any adverse impacts on local fishing communities. Finally, the document concludes by detailing how the costs and earnings information could be used to develop economic models that evaluate management proposals. (PDF contains 147 pages)

As part of a multibeam and side scan sonar (SSS) benthic survey of the Marine Conservation District (MCD) south of St. Thomas, USVI and the seasonal closed areas in St. Croix—Lang Bank (LB) for red hind (Epinephelus guttatus) and the Mutton Snapper (MS) (Lutjanus analis) area—we extracted signals from water column targets that represent individual and aggregated fish over various benthic habitats encountered in the SSS imagery. The survey covered a total of 18 km2 throughout the federal jurisdiction fishery management areas. The complementary set of 28 habitat classification digital maps covered a total of 5,462.3 ha; MCDW (West) accounted for 45% of that area, and MCDE (East) 26%, LB 17%, and MS the remaining 13%. With the exception of MS, corals and gorgonians on consolidated habitats were significantly more abundant than submerged aquatic vegetation (SAV) on unconsolidated sediments or unconsolidated sediments. Continuous coral habitat was the most abundant consolidated habitat for both MCDW and MCDE (41% and 43% respectively). Consolidated habitats in LB and MS predominantly consisted of gorgonian plain habitat with 95% and 83% respectively. Coral limestone habitat was more abundant than coral patch habitat; it was found near the shelf break in MS, MCDW, and MCDE. Coral limestone and coral patch habitats only covered LB minimally. The high spatial resolution (0.15 m) of the acquired imagery allowed the detection of differing fish aggregation (FA) types. The largest FA densities were located at MCDW and MCDE over coral communities that occupy up to 70% of the bottom cover. Counts of unidentified swimming objects (USOs), likely representing individual fish, were similar among locations and occurred primarily over sand and shelf edge areas. Fish aggregation school sizes were significantly smaller at MS than the other three locations (MCDW, MCDE, and LB). This study shows the advantages of utilizing SSS in determining fish distributions and density.

Rainbow smelt (Osmerus mordax) are small anadromous fish that live in nearshore coastal waters during much of the year and migrate to tidal rivers to spawn during the spring. They are a key prey species in marine food webs, as they are consumed by larger organisms such as striped bass, bluefish, and seabirds. In addition, smelt are valued culturally and economically, as they support important recreational and commercial fisheries. The Atlantic Coast range of rainbow smelt has been contracting in recent decades. Historically, populations extended from the Delaware River to eastern Labrador and the Gulf of St. Lawrence (Buckley 1989). More recent observations indicate that rainbow smelt spawning populations have been extirpated south of Long Island Sound, and evidence of spawning activity is extremely limited between Long Island and Cape Cod, MA. In the Gulf of Maine region, spawning runs are still observed, but monitoring surveys as well as commercial and recreational catches indicate that these populations have also declined (e.g., Chase and Childs 2001). Many diverse factors could drive the recently noted declines in rainbow smelt populations, including spawning habitat conditions, fish health, marine environmental conditions, and fishing pressure. Few studies have assessed any of these potential threats or their joint implications. In 2004, the National Marine Fisheries Service (NMFS) listed rainbow smelt as a species of concern. Subsequently, the states of Maine, New Hampshire, and Massachusetts were awarded a grant through NMFS’s Proactive Conservation Program to gather new information on the status of rainbow smelt, identify factors that affect spawning populations, and develop a multi-state conservation program. This paper provides an overview of this collaborative project, highlighting key biological monitoring and threats assessment research that is being conducted throughout the Gulf of Maine.
