Non-stimulating tradition: The Effect of Temperament on Painting Art Preferences
Joanna Rz?dkowska,Alicja Paracka,Natalia Frankowska
Avant : Journal of Philosophical-Interdisciplinary Vanguard , 2010,
Abstract: This study examined the effect of temperament on preferences for painted artwork. Our preferences are determined by different personality traits. The study presented here was a replication of the current study of Terror Management Theory (TMT) with the structures of temperament as individual differences. The results showed significant differences in preferences for traditional and modern art, depending on the degree of harmonization of the temperamental structures. Sanguines and melancholics in the no fear condition evaluated modern art most highly, however in the fear condition they evaluated traditional art most highly. This effect confirms the importance of individual differences and the situational variability of preferences in art.

Infection cases in infants and small children with atopic dermatitis – own observations
Helena Rotsztejn,Joanna Frankowska,Barbara Kamer,Ewa Trznadel-Grodzka
Post?py Higieny i Medycyny Do?wiadczalnej , 2012,
Abstract: Introduction:The purpose of the work is to estimate the frequency of occurrence of various infections in infants and small children, aged between 0 and 36 months with atopic dermatitis in the practice of a family doctor.Material/Methods:The study has been conducted on the basis of the retrospective analysis of medical documentation of disease among children born in 2005–2008 treated in Outpatient Clinic of the Polish Mother’s Memorial Hospital in Lodz.Results:Children suffering from atopic dermatitis are more prone to develop infectious diseases.Conclusions:Infectious diseases in children with atopic dermatitis are of more chronic nature and more often require antibiotic therapy. Such children often manifest chronic diarrhea and their stool contains Staphylococcus aureus. They are more often hospitalized because of difficulty in setting a diagnosis and applying treatment in outpatient clinics.
Atopic dermatitis in a general practitioner practice. Atopowe zapalenie skóry w praktyce lekarza rodzinnego.
Joanna Frankowska,Ewa Trznadel-Bud?ko,Helena Rotsztejn
Clinical Dermatology , 2009,
Abstract: Since allergic diseases are more and more common nowadays, they are a very important clinical problem. The effective treatment of these diseases in childhood may contribute to decreasing diseases at a later time. The role of general practitioners in diagnosing atopic dermatitis is extremely significant, because they are the first who examine children with atopic lesions. They ought to educate parents about the basic knowledge, identification and elimination contributing factors of atopic dermatitis and systematically control children's health. The treatment should be based on the close cooperation of general practitioners, paediatricians, allergologists and dermatologists because atopic dermatitis may be the starting point of chronic disease process.
Autonomous Integral Functionals with Discontinuous Nonconvex Integrands: Lipschitz Regularity of Minimizers, DuBois-Reymond Necessary Conditions, and Hamilton-Jacobi Equations
Gianni Dal Maso,Helene Frankowska
Mathematics , 2002,
Abstract: This paper is devoted to the autonomous Lagrange problem of the calculus of variations with a discontinuous Lagrangian. We prove that every minimizer is Lipschitz continuous if the Lagrangian is coercive and locally bounded. The main difference with respect to the previous works in the literature is that we do not assume that the Lagrangian is convex in the velocity. We also show that, under some additional assumptions, the DuBois-Reymond necessary condition still holds in the discontinuous case. Finally, we apply these results to deduce that the value function of the Bolza problem is locally Lipschitz and satisfies (in a generalized sense) a Hamilton-Jacobi equation.
Value Functions for Bolza Problems with Discontinuous Lagrangians and Hamilton-Jacobi Inequalities
G. Dal Maso,H. Frankowska
Mathematics , 2000,
Abstract: We investigate the value function of the Bolza problem of the Calculus of Variations $$ V (t,x)=\inf \{\int_{0}^{t} L (y(s),y'(s))ds + \phi(y(t)) : y \in W^{1,1} (0,t; R^n) ; y(0)=x \}, $$ with a lower semicontinuous Lagrangian $L$ and a final cost $\phi$, and show that it is locally Lipschitz for $t>0$ whenever $L$ is locally bounded. It also satisfies Hamilton-Jacobi inequalities in a generalized sense. When the Lagrangian is continuous, then the value function is the unique lower semicontinuous solution to the corresponding Hamilton-Jacobi equation, while for discontinuous Lagrangian we characterize the value function by using the so called contingent inequalities.
Uniqueness of solutions to Hamilton-Jacobi equations arising in the Calculus of Variations
G. Dal Maso,H. Frankowska
Mathematics , 2000,
Abstract: We prove the uniqueness of the viscosity solution to the Hamilton-Jacobi equation associated with a Bolza problem of the Calculus of Variations, assuming that the Lagrangian is autonomous, continuous, superlinear, and satisfies the usual convexity hypothesis. Under the same assumptions we prove also the uniqueness, in a class of lower semicontinuous functions, of a slightly different notion of solution, where classical derivatives are replaced only by subdifferentials. These results follow from a new comparison theorem for lower semicontinuous viscosity supersolutions of the Hamilton-Jacobi equation, that is proved in the general case of lower semicontinuous Lagrangians.
Sensitivity relations for the Mayer problem with differential inclusions
Piermarco Cannarsa,Helene Frankowska,Teresa Scarinci
Mathematics , 2014,
Abstract: In optimal control,sensitivity relations are usually understood as inclusions that identify the pair formed by the dual arc and the Hamiltonian, evaluated along the associated minimizing trajectory, as a suitable generalized gradient of the value function. In this paper, sensitivity relations are obtained for the Mayer problem associated with the differential inclusion $\dot x\in F(x)$ and applied to derive optimality conditions. Our first application concerns the maximum principle and consists in showing that a dual arc can be constructed for every element of the superdifferential of the final cost. As our second application, with every nonzero limiting gradient of the value function at some point $(t,x)$ we associate a family of optimal trajectories at $(t,x)$ with the property that families corresponding to distinct limiting gradients have empty intersection.
Participation and Activity Rates: Monitoring Exposure Potential for Native Americans and Others in the United States  [PDF]
Joanna Burger
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.28116
Abstract: Managers and regulators are concerned about potential human health effects from exposure on lands contaminated by chemicals and radionuclides. Determining target cleanup levels is partly dependent upon future land use, and potential exposure from human use. This paper provides data from surveys of activity patterns of people attending festivals in four states, located in the vicinity of Department of Energy facilities. There were significant differences in both participation rates, and activity rates as a function of both location and ethnicity that can be used by managers to track exposure, land use, and preferred activities on natural lands. In general, 1) a higher percent of Native Americans engaged in consumptive activities than others, 2) a higher percent of Caucasians engaged in some non-consumptive activities than Native Americans, 3) a higher percentage of Native Americans engaged in activities on sacred grounds, 4) activity rates were generally higher for Native Americans for consumptive activities and religious/cultural than for Caucasians, 5) fishing rates were higher than other consumptive activities, and camping/hiking were higher than other non-con- sumptive activities, and 6) hunting rates were higher in subjects from Idaho than elsewhere. Baseline human use is critical for monitoring potential exposure, and provides the basis for monitoring, risk assessment and future land use, and these data can be used by managers for assessment and management. Tracking changes over time will reflect changing recreational, subsistence, and cultural/religious trends that relate to land use, public perceptions, and exposure.
In-Arrears Interest Rate Derivatives under the 3/2 Model  [PDF]
Joanna Goard
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.66067
Abstract: Lie symmetry methods are used to find a closed form solution for in-arrears swaps under the 3/2 model \"\". As well, approximate solutions are found for short-tenor in-arrears caplets and floorlets under the same interest rate model. Comparisons are made of the approximate option values with those obtained with a computationally-intensive numerical scheme. The approximate pricing is found to be substantially fast and easy to implement, while the relative errors with respect to the “true” prices are very small.
