Bahía de Coishco, Chimbote, Perú: una visión integral de sus recursos vivos y su ambiente. 2001 - 2005

Se ha recorrido la Bahía de Coishco a fin de conocer las actividades artesanal e industrial que se desarrollan en esta área, y se han revisado los informes sobre las actividades y proyectos que ejecuta el Laboratorio Costero de Chimbote como parte del Plan Anual de Trabajo Institucional. Se presenta una descripción de la morfología, topografía y sedimentología de la Bahía de Coishco, así como de las características físicas, químicas y biológicas de sus masas de agua. Se hace una descripción de las fuentes y niveles de contaminación, producto del vertimiento de aguas de diferentes tipo de uso: industrial, pesquero, doméstico; de escorrentía y producto de actividades de las embarcaciones que operan en esta bahía. Se mencionan las especies que sustentan la pesca artesanal e industrial, los instrumentos y áreas de pesca, los bancos naturales de invertebrados marinos, los tonelajes de extracción a nivel artesanal y de procesamiento a nivel industrial por cada una de las fábricas que operan en esta bahía. La bahía de Coishco, con un área aproximada de 11.655 km2 es una bahía abierta, rodeada por las islas Santa y Moñaque; en sus profundidades predominan las isóbatas desde 12 a 16 m y en el centro de la bahía existe alta concentración de materia orgánica. Las masas de agua son generalmente Aguas Costeras Frias, de 15 a 20 ºC; la salinidad cerca de la línea litoral es menor a 35 ups, en cambio en el sur de la balúa las salinidades son en promedio del orden de 35,1ups. El vertimiento de aguas de uso industrial pesquero y doméstico influye en el contenido de oxígeno tanto superficial como de fondo, habiéndose detectado situaciones de anoxia; igualmente se afectan los nutrientes, tal es así que los niveles de fosfatos se incrementan durante la época de intensa actividad pesquera y disminuyen durante la época de veda. Se ha identificado 60 especies de organismos planctónicos, destacando las diatomeas de afloramiento Chaetoceros decipiens, Thalassiosira rotula y Skeletonema costatum. Los peces constituyen la principal fuente de pesca artesanal (82% de las capturas), destacando: "lorna" Sciaena deliciosa, "pejerrey" Odonthestes regia regia, "machete" Etmidium maculatum, "cachema" Cynoscion analis, "cabinza" Isacia conceptionís. La anchoveta es la principal materia prima para la elaboración de harina y aceite de pescado. Entre los invertebrados, destacaron "caracol" Stramoníta chocolata, "almeja" Semele spp., "concha de abanico" Argopecten purpu­ratus, "pulpo" Octopus mimus.

Psychodynamic psychotherapy in newly diagnosed cancer patients: a randomized controlled trial

Background and aims: More than 30% of cancer patients develop a psychiatric disorder during the evolution of their disease. While evidence exists, that psychotherapy can improve psychological distress, questions, such as the prevalence of patients accepting psychotherapy, treatment indications and effectiveness of psychotherapeutic interventions in the oncology setting remain unanswered. The aims were: (1) To assess the prevalence of newly diagnosed cancer patients motivated to engage in psychotherapeutic interventions; (2) to identify those who benefit; and (3) to evaluate their effectiveness. Methods: Every new patient of the Oncology Service at the University Hospital Lausanne was informed of the possibility of benefitting from psychotherapeutic support. Patients who accepted were randomly assigned to individual psychotherapy or to a 4-month waiting list. Psychotherapies were formalized as psychodynamicoriented short interventions (1-4 sessions) or brief psychodynamic psychotherapies (16 sessions). Patients who refused psychotherapy were asked to participate in an observational group. Socio-demographic and medical data, anxiety, depression, alexithymia and quality of life (SCL- 90, HADS, TAS, EORTC) of all participants were evaluated at base line and at 1, 4, 8 and 12 -months Follow- Up. Results: So far 1047 patients have been approached, 20% were included in the study (intervention n=68, observation n=122), 32% were excluded, 22% could not be contacted and 26% refused to participate. At baseline, patients who accepted psychotherapeutic support showed higher depression and anxiety scores (HADS, SCL-90) compared to controls. 56% benefited from 4 sessions of psychological support, 44% engaged in 16 sessions of brief psychodynamic therapy. Conclusions: The preliminary results of this ongoing trial suggest that a minority of newly cancer patients accept psychotherapeutic intervention. These patients are more depressed than controls. Their motivation for short interventions and for brief psychotherapies is comparable.

How Does Addressing Patient's Defenses Help to Repair Alliance Ruptures in Psychodynamic Psychotherapy?: An Exploratory Study.

Interpreting or addressing defenses is an important aspect of psychoanalytic technique. Previous research has shown that therapist addressing defenses (TADs) can produce a positive effect on alliance. The potential value of TADs during the process of alliance rupture and resolution has not yet been documented. We selected patients (n = 17) undertaking a short-term dynamic psychotherapy in which the therapeutic alliance, measured with the Helping Alliance Questionnaire and monitored after each session, showed a pattern of rupture and resolution. Two control sessions (5 and 15) were also selected. Presence of TADs was examined in each therapist interpretation. Compared with control sessions, rupture sessions were characterized by fewer TADs and especially fewer TADs addressing specifically intermediate-essentially neurotic-defenses. Resolution sessions were characterized by more TADs addressing specifically intermediate defenses. This confirms the link between therapist technique and alliance process in psychodynamic psychotherapy.

Psychotherapy for Personality Disorders in a Natural Setting: A Pilot Study over Two Years of Treatment.

Long-term assessment of the effects of psychotherapy for personality disorders (PDs) in a natural environment is an important task. Such research contributes to enlarge the practice-based evidence, embedded in broad collaborations between clinicians and researchers in psychotherapy for PDs. The present pilot study used rigorous assessment procedures and incorporated feedback loops of outcome information to the therapists in demonstrating the effects of psychotherapy for PD in a natural setting. The number of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), criteria for any PD was the primary outcome (along with psychological distress, depression, impulsiveness, and quality of life as secondary measures), assessed at intake, 6, 12, 18, and 24 months of psychotherapy for N = 13 patients with PD. Data were analyzed using hierarchical linear modeling. Results demonstrated a large pre-post effect (d = 2.22) for the observer-rated measure (primary outcome), and small to medium effects for the secondary outcomes; these results were corroborated by a steady decrease of symptoms over all five time points, which was significant for several outcomes. These results add a piece to the literature by demonstrating the effects of long-term psychotherapy for PDs in increasingly diverse contexts and suggest that practice-oriented research can be carried out in a collaborative and systematic manner.

On the path integral formulation and the evaluation of quantum statistical averages

Four problems of physical interest have been solved in this thesis using the path integral formalism. Using the trigonometric expansion method of Burton and de Borde (1955), we found the kernel for two interacting one dimensional oscillators• The result is the same as one would obtain using a normal coordinate transformation, We next introduced the method of Papadopolous (1969), which is a systematic perturbation type method specifically geared to finding the partition function Z, or equivalently, the Helmholtz free energy F, of a system of interacting oscillators. We applied this method to the next three problems considered• First, by summing the perturbation expansion, we found F for a system of N interacting Einstein oscillators^ The result obtained is the same as the usual result obtained by Shukla and Muller (1972) • Next, we found F to 0(Xi)f where A is the usual Tan Hove ordering parameter* The results obtained are the same as those of Shukla and Oowley (1971), who have used a diagrammatic procedure, and did the necessary sums in Fourier space* We performed the work in temperature space• Finally, slightly modifying the method of Papadopolous, we found the finite temperature expressions for the Debyecaller factor in Bravais lattices, to 0(AZ) and u(/K/ j,where K is the scattering vector* The high temperature limit of the expressions obtained here, are in complete agreement with the classical results of Maradudin and Flinn (1963) .

Generating finite integral relation algebras

Relation algebras and categories of relations in particular have proven to be extremely useful as a fundamental tool in mathematics and computer science. Since relation algebras are Boolean algebras with some well-behaved operations, every such algebra provides an atom structure, i.e., a relational structure on its set of atoms. In the case of complete and atomic structure (e.g. finite algebras), the original algebra can be recovered from its atom structure by using the complex algebra construction. This gives a representation of relation algebras as the complex algebra of a certain relational structure. This property is of particular interest because storing the atom structure requires less space than the entire algebra. In this thesis I want to introduce and implement three structures representing atom structures of integral heterogeneous relation algebras, i.e., categorical versions of relation algebras. The first structure will simply embed a homogeneous atom structure of a relation algebra into the heterogeneous context. The second structure is obtained by splitting all symmetric idempotent relations. This new algebra is in almost all cases an heterogeneous structure having more objects than the original one. Finally, I will define two different union operations to combine two algebras into a single one.

Prime Rational Functions and Integral Polynomials

Let f(x) be a complex rational function. In this work, we study conditions under which f(x) cannot be written as the composition of two rational functions which are not units under the operation of function composition. In this case, we say that f(x) is prime. We give sufficient conditions for complex rational functions to be prime in terms of their degrees and their critical values, and we derive some conditions for the case of complex polynomials. We consider also the divisibility of integral polynomials, and we present a generalization of a theorem of Nieto. We show that if f(x) and g(x) are integral polynomials such that the content of g divides the content of f and g(n) divides f(n) for an integer n whose absolute value is larger than a certain bound, then g(x) divides f(x) in Z[x]. In addition, given an integral polynomial f(x), we provide a method to determine if f is irreducible over Z, and if not, find one of its divisors in Z[x].
