Seductive symbolism: Psychoanalysis in the context of oncology.

Beliefs about what caused their cancer are a central facet of patients' experience of illness. These beliefs make up the patient's theory of etiology, which derives from various sources, including conscious and unconscious fantasy. This paper highlights this dimension of patients' experience, and the possible interaction between patients' psychogenic theories of etiology and their therapists' potentially generated psychogenic theories regarding patients' disease. It is suggested that a countertransferential pull for therapists exists to generate psychogenic theory regarding patients' cancer in the face of the threat of impotency it presents. This is discussed as a seductive pull into symbolism-based understanding of patients' cancer etiology—a pull this paper aims to characterize. It is suggested that the seductive pull results from the influence of psychoanalytic psychosomatic theory in the context of the dynamic between the ill patient and the therapist. Some psychoanalytic psychosomatic theory posits symbolism-based linear psychogenesis and the possible correction of soma via psyche in a great variety of illnesses and conditions, including cancer, and the hypothetical effect of this literature on the clinician's mindset and clinical work is considered. Specifically, it is suggested that this portion of our literature might serve a psychological function for clinicians, as it can help to shore up an omnipotence defense against the undertow of chaos inherent in cancer-related bodily dysfunction. More generally, it is argued that the context of existing psychoanalytic psychosomatic theory characterized by a focus on symbolism-based linear psychogenesis is potentially influential, and that this influence needs to be examined.

Energy inputs and crop yield relationship in potato production in Hamadan province of Iran

The aim of this study was to determine energy consumption and the relationship between energy input and yield for potato production in Kaboud Rahang region of Hamadan state. The data used in this study are collected by questionnaire. The results revealed that nitrogen fertilizer (39%), diesel (21%), seed (14.9%), water (7.5%) and manure (6.4%) consumed the bulk of energy. In the surveyed farms, average yield and energy consumption were calculated as around 28613.7 kg/ha, 92296.3 MJ/ha, respectively. The results also showed that energy ratio, specific energy and energy productivity were 1.1, 3.2 MJ/kg and 0.3 kg/MJ, respectively. An econometric model was developed to estimate the impact of energy inputs on yield by using parametric methods. For this purpose, potato yield, an endogenous variable was assumed to be a function of energy inputs: fertilizer manure, chemical, machinery, human, water for irrigation, diesel and seed. The empirical results indicated that variables: fertilizer, chemical, seed and human were found statistically significant and contributed to yield. Among statistically significant exogenous variables, seed, water for irrigation, chemical, human and fertilizer were ranked in terms of elasticities.     

Different ways of moving ahead after analysis: Changes in experiential dimensions.

Within research on psychoanalysis, the common model of analytic change conceptualizes it as structural reorganization and development of self-analytic function. The present article takes as its point of departure analytic patients who, in follow-up interviews, do not present their experience of change according to this common model. Instead of categorizing analysands as being either successful or unsuccessful cases, the article aims to develop concepts of change that pertain to the experiential domain. Themes in the self experience of three former patients are explored. The data is gathered through follow-up interviews. The interviews were conducted with an analytic approach, which provides data on transference themes. Data from the interviews is not intended to provide empirical support for outcomes, but provides material from which concepts of change can be explored and discussed. The three cases illustrate three distinct psychic dimensions: safety, meaningfulness and sameness. All the cases have in common that they show, as described by Modell (1990), a containing transference in the follow-up interviews. Based on the postulated dimensions of self-experience, and with the view that containing transference is a common theme, it is further argued that, despite showing object-dependency, these informants have undergone an experiential change that is of existential significance. This is a kind of change that, it may be argued, is beyond a structural one; one that may be conceptualized as a precondition for the kind of change assumed by the main analytic model. To develop a self-analytic function, the patient may first need to develop a containing one. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Formability prediction of advanced high strength steels using constitutive models characterized by uniaxial and biaxial experiments

Sheet formability, as determined by the limiting dome height (LDH) test, was evaluated for DP and TRIP steel sheet samples. The LDH test was also predicted with finite element (FE) simulations using various constitutive models. Three yield functions, von Mises, Hill's 1948, and Yld2000-2d, were considered to examine the effect of the yield criterion on formability. The anisotropy parameters were determined from different experimental tests and their influences on LDH predictions were analyzed. For Hill's 1948 model, the coefficients were calculated either using the yield stresses or r-values measured in different tension directions. The anisotropy coefficients of the Yld2000-2d were determined using in-plane biaxial test data in addition to the conventional uniaxial test-based data. The stress-strain curves for hardening characterization were measured using uniaxial and bulge tests. The latter provides the flow stress over an extended strain range, compare with uniaxial tension, without showing instability. The constitutive models were implemented in a FE code with a user material subroutine. They were evaluated by comparing the experimental and predicted punch load–displacement and sheet thickness variations after forming in the LDH test. The results for this particular example demonstrated that the non-quadratic yield function and the hardening curve of the bulge test improve the prediction accuracy for sheet forming and formability analyzes significantly.

Estimating capital costs of wastewater treatment plants at the strategical level

ABSTRACT

The present paper aims at the establishment and testing of construction cost functions for wastewater treatment plants (WWTP) based on their hydraulic and physical characteristics. A five-step methodology is followed: (1) database construction and asset characterization; (2) present cost value calculation; (3) key parameters and cost functions establishment; (4) cost modelling; and (5) model testing. A large set of construction costs and infrastructure data from several Portuguese wastewater utilities is analysed including 147 WWTP. Simple linear regression analysis is carried out to obtain cost functions for five types of WWTP. The cost modelling also includes the estimation of 90% prediction bands. Each developed cost function is tested for checking their statistical significance. Results allow the estimation of capital costs of new WWTP and the assessment of the current value of existing assets at the strategical and tactical planning levels without the knowledge of the specific components of the facilities.     

Optimal seismic design of steel structures by an efficient soft computing based algorithm

The main aim of this study is to propose advanced soft computing techniques for the optimal seismic design of real steel structures subjected to natural ground motion records. For the solution of the optimization problem an efficient combination of the particle swarm optimization (PSO) and adaptive virtual sub-population (AVSP) algorithms is proposed. Also an efficient combination of the adaptive neuro-fuzzy inference system (ANFIS), wavelet transforms (WT) and radial basis function (RBF) neural networks, termed as fuzzy wavelet radial basis function (FWRBF), is proposed to accurately predict the structural responses. The numerical results demonstrate the computational advantages of the proposed methodology.
