Distinguishing Between Spatial Heterogeneity and Inefficiency: Spatial Stochastic Frontier Analysis of European Airports
Authors: Dmitry Pavlyuk 
Published: February 2013

Abstract
A problem of distinguishing between frontier heterogeneity and inefficiency is widely acknowledged in benchmarking. A special type of heterogeneity, based on the spatial structure, can significantly affect performance estimates in the airport industry. In this research we presented a general specification of the spatial stochastic frontier model, which includes spatial lags, spatial autoregressive disturbances and spatial autoregressive inefficiencies. Maximum likelihood estimator has been derived for this model. Applying the suggested model specification to the European airports dataset, we discovered presence of significant spatial heterogeneity, which leads to biased estimates of efficiency, received using classical models.

Abstract
The aim of this study was the morphological characterisation of glioblastoma multiforme tumour grown in ovo. Tumour cells (U-87 MG) were implanted on the chorioallantoic membrane of chicken egg. The structural features of cultured tumours resembled the spontaneous glioblastoma multiforme; however, the differences were also indicated. Our results confirm applicability of in ovo culture in tumour genesis studies. The described novel model may be profoundly helpful for the future research on molecular mechanisms of tumour growth inhibition.

Published: February 2013

Abstract
Blood morphology in dogs infected with intracellular parasites of the genera Babesia and Ehrlichia was examined. The parasites were detected in peripheral blood smears stained by the May-Grünwald-Giemsa method. During the parasitic invasion, a decrease in thrombocyte counts was observed. This was connected with forming platelet aggregates. It was noted that the number of giant platelets simultaneously increased.
Psychological characteristics of juvenile offenders with constant integration problems
Authors: Démuthová Slávka 
Published: February 2013

Abstract
The aim of this study is to identify the typical psychological, demographic, socio-economical, educational, health, and criminological characteristics of juvenile delinquents who tend to continue in their criminal career to adulthood and therefore obstruct the possibility of successful, non-offending integration to society. Subjects of research were young male prisoners jailed in the Juvenile imprisonment house that completed the test battery. By ex-post analysis after a period of five years, the differences between offenders and non-offenders were identified. Results show significant differences in the age of prisoners, length of imprisonment, presence of violent offence (esp. robbery) in the criminal history, number of previous offences recorded, differences in factors i, h, and q1 from the Sixteen Personality Factor Questionnaire, responses within the Hand test characteristic (affection, dependence, and communication), and in several signs of the drawings in a Draw-A-Person test. The importance and influence of listed factors is discussed.
Self-efficacy beliefs of youth entering the labour market
Authors: Kot Paweł , Rożnowski Bohdan 
Published: February 2013

Abstract
This article presents the psychological meaning of school-to-work transition. Transition to taking up new social roles entails numerous difficulties, and that is why young people see it as a crisis point. According to researchers one of the predictors of effective transition to the labour market is self-efficacy.
This article presents the two obtaining approaches to the psychology of self-efficacy beliefs. Both specific and generalized self-efficacy belief are good predictors of human behaviour, which has been repeatedly confirmed in the studies (main overview in this article).
The authors of this compilation have integrated the two dominating approaches into one theoretical model, taking account of the three levels of generality proposed by Rosch. By doing that, a theoretical model has been created which allows for organising self-efficacy beliefs relating to life roles into a three-level hierarchical structure.
T-Cell Receptor-G Gene Rearrangement Analysis in the Diagnosis of Patients with Erythroderma / Dijagnostički Značaj Analize Preuređenja Gena Gama Lanca T-Ćelijskog Receptora Kod Pacijenata Sa Eritrodermijom

Published: February 2013

Abstract
The diagnosis of erythroderma is challenging, since clinical, histopathological and immunophenotypic findings are insufficient to differentiate between inflammatory and lymphomatous erythroderma. Thus, multiplex PCR was used for T-cell receptor-γ gene rearrangement analysis, in the skin and peripheral blood samples of 24 patients (20 men and 4 women) with erythroderma of varying origin, in order to estimate its diagnostic value. Cutaneous T-cell lymphoma was confirmed in 9, benign inflammatory dermatosis in 12, and idiopathic erythroderma and clonal dermatitis in 3 patients. In the group of patients with erythrodermic cutaneous T-cell lymphoma, the dominant clone was detected in the skin of 8/9, and in none of the patients with inflammatory dermatoses. A dominant clone was found in peripheral blood of 5/6 samples of patients with erythrodermic cutaneous T-cell lymphoma, and in 2/12 patients with inflammatory dermatosis. T-cell receptor-γ gene rearrangement analysis is valuable in differentiation between inflammatory and lymphomatous erythroderma, thus substantially improving the diagnosis of patients with erythroderma.
Actinic Keratosis: A New Approach to the Treatment / Aktinična Keratoza: Novi Pristup Lečenju
Authors: Karadaglić Đorđije , Jovanović Marina 
Published: February 2013

Abstract
Actinic keratosis is an intraepidermal proliferation of transformed, atypical keratinocytes, induced by exposure to solar ultraviolet radiation. Many authors believe that it is the earliest form of squamous cell carcinoma. More than 40% of all metastatic squamous cell carcinomas develop from actinic keratosis. The clinical, histological and molecular characteristics of actinic keratosis are those of squamous cell carcinomas. Since it can be extremely hard to distinguish actinic keratosis from some squamous cell carcinomas, treatment can be rather difficult. The best treatment of actinic keratosis is its prevention. The main reason for therapy which is universally accepted, is prevention of squamous cell carcinoma. A number of options are available, but when considering the efficacy, invasive procedures remain the standard treatment. Treatment of individual lesions may prevent further progression of actinic damage present in the surrounding skin
Erythrodermic cutaneous T-cell lymphoma: Two case reports / Eritrodermalni kutani limfom T-ćelija - prikaz dva slučaja

Published: February 2013

Abstract
Primary cutaneous T-cell lymphomas (CTCLs) are Non-Hodgkin lymphomas where skin may be the only involved organ for a long time. The erythrodermic form of CTCL, including Sezary syndrome, with increased IgE concentration, eosinophilia and intense pruritus, may suggest atopic dermatitis, in the lack of evidence for diagnosis of T-cell lymphoproliferative disorder. After vigorous research, two patients with erythroderma, increased IgE and eosinophilia, were not diagnosed with CTCL. Adult atopic dermatitis was diagnosed, based on clinical examination and histopathologic analysis of the skin sample. Therapy with oral cyclosporin A (CsA) and systemic corticosteroids were initiated, but the improvement was minimal and short-lived. Disease progression was noted in both patients, after a month of cyclosporine therapy: malaise, subfebrile and febrile temperatures, and development of generalized skin nodules were evident. In the first patient (aged 30) repeated examinations confirmed presence of Sezary cells in peripheral blood samples, dominant T-cell clone in the skin, peripheral blood and bone marrow, whereas the last repeated histopathologic analysis revealed T-lymphoproliferative skin disorder. In the second patient, (aged 44) primary cutaneous CD30+ T-cell lymphoma was diagnosed, based on histopathologic analysis of the newly appearing skin nodule. Differential diagnosis of erythroderma is always difficult, since clinical, histopathologic and immunophenotypic findings are frequently insufficient to differentiate between inflammatory and lymphomatous erythroderma. Treatment with cyclosporin A always demands carefull evaluation of the course of the disorder.

Abstract
Basal cell carcinoma (BCC) is the most common type of skin cancer in the Caucasian population. However, BCC of the genitalia is extremely rare. To the best of our knowledge, only 30 patients with BCC of the genitalia have been reported in the literature so far. BCC usually occurs in individuals over the age of 50, on sun-exposed areas of the body, and it is more prevalent in females. Superficial BCCs account for approximately 10% of BCC, and are commonly found on the trunk or limbs. This is a report on a 55-year-old male patient with penile BCC, and a literature review on this condition. The patient presented with asymptomatic skin lesions in the genital area which progressed during the last 15 years. Before admission, the patient received: antimycotics, antiviral, antibacterial and corticosteroid therapy, but without any improvement. Examination of the proximal penile skin revealed a sharply marked, smooth and shiny erythematous plaque of about 3.3 x 2 cm, with whitish squamae in the central zone. The histopathology finding revealed a superficial BCC and total excision was recommended. Treatment of the superficial BCC depends on its size and location. It includes surgical removal with possible reconstruction, radiotherapy, application of immunomodulators, local chemotherapy and local retinoid therapy. Although this is an extremely rare type of BCC, it is important to keep in mind that it may affect body areas seldom exposed to direct sunlight.
Linear porokeratosis: a case report
Authors: Stojanović Slobodan , Jovanović Marina , Vučković Nada ,   Ivkov-Simić, Tasić Siniša 
Published: February 2013

Abstract
Porokeratosis is a rare genodermatosis based on chronic keratinization disorder histologically characterized by the presence of a cornoid lamella and various clinical manifestations. Five most commonly described types of poroketarosis are porokeratosis of Mibelli or ”classic” porokeratosis, disseminated superfi cial actinic porokeratosis, disseminated palmoplantar porokeratosis, linear porokeratosis, and punctate porokeratosis. In all of the fi ve clinical types of porokeratosis described today, cases of planocellular skin carcinoma are described, except in punctate type cases. Use of topical CO2 laser ablation, cryotherapy and topical use of 5% Imiquimod cream, have shown favorable effects in local treatment of porokeratosis. The authors present a clinical case of a girl suffering from linear porokeratosis over the course of the last four years, spreading on the inside of her right arm along the lines of Blaschko. Linear porokeratosis was histologically confi rmed by biopsy of skin lesions and dermoscopy. Dermoscopic fi ndings, used as an auxiliary method, also indicated linear porokeratosis. Successful liquid nitrogen cryotherapy prompted the authors to present a case in which the applied treatment proved to be successful, but also to emphasize the need for timely treatment in order to prevent malignant alterations of these changes.

Abstract
Karosienė J., Kasperovičienė J., 2012: Peculiarities of epiphyton algal communities formation on different macrophyte species [Skirtingų makrofitų rūšių epifitono dumblių bendrijų formavimosi ypatumai]. - Bot. Lith., 18(2): 154-163.
The epiphyton on different aquatic vegetation represented by emerged macrophytes (Phragmites australis, Equisetum fluviatile, Schoenoplectus lacustris), floating-leaved plants (Nuphar luteum) and submerged macrophytes (Potamogeton perfoliatus, Chara rudis) was studied in two meso- and mesoeutrophic lakes. The morphological characteristics, physiological and synecological peculiarities of plant host had more effect on epiphyton algae abundance and biomass than species richness. The highest densities of algae were associated with helophytes Phragmites australis, Equisetum fluviatile, the lowest was recorded on Schoenoplectus lacustris and laminae of Nuphar luteum. Loosely attached diatoms prevailed on helophytes, adnate species on Nuphar luteum laminae. Cyanobacteria and green algae were more abundant on Nuphar luteum laminae and Potamogeton perfoliatus.
Atypical meningioma
Authors: Iacob G. , Craciun M. 
Published: February 2013

Abstract
Objective: Atypical meningioma are an intermediate group of meningiomas, exhibiting less favourable biological behavior than classic benign tumours, but a relatively more favourable biological behavior than definitive malignant meningiomas. Subject of controversy, atypia in meningioma still generate discordance between accurate criteria defining malignancy and biological behavior, prediction of recurrence.
Methods: This retrospective study intend to evaluate diagnosis on clinical and pathological data, treatment trends and early outcomes for 6 cases with atypical meningiomas occuring in 63 patients operated for benign meningioma in the last 5 years in our clinic between 2006-2011. All patients were explored CT, MRI, preoperative selective angiography and in all cases the WHO 2000 classification criteria were used to define atypical meningioma
Results: Between 2006-2011 we operated 6 atypical meningioma of 63 benign meningiomas (9,52%). Tumor sites in the patients were: parasagittal (3 cases), convexity (2 cases), spheno-cavernous (1 case). All patients were operated and dural graft was done to all cases. The extent of surgical resection was Simpson’s grade 1 in 2 cases and Simpson’s grade 2 in four cases, to which radiation was administered after the first surgery with a dose ranging from 52-62 Gy. Regrowth (enlargement of tumour after subtotal resection) was noticed in 2 irradiated cases: one case after 2 years after the first operation, the patient was again operated - pathological diagnosis was malignant meningioma; in another case after 3 years, at operation it was the atypical meningioma. No chemotherapy was used in our cases.
Conclusions: Atypical meningiomas are rare tumors, grow more rapidely, the diagnosis age ≥ 60 years, several histological criteria can define accurate identification to understand the biology of this group of tumors. Heterogenous contrast enhancement with marked peritumoral edema in neuroimaging are important; cerebral edema has prognostic value and should encourage fundamental and farmacologic research using anti VEGF and somatostatine analogs treatments. Surgery (Simpson grade 1) referring both tumor and dural implant area should be done de novo but also for recurrencies. Radiotherapy still are controversial without proven benefit and chemotherapy without statistic argues to improve quality of life.
Patriotism and Imperialism 1870-1914 Education & the Young
Authors: Gannon David 
Published: February 2013

"Propaganda aims to to turn resentment into rebellion or loose coalition into unity." (Mangan, 1986, p. 113)
Contemporary commentators and historians alike have commented on the way patriotic and imperial propaganda 'mush­roomed' (Porter, 2004, p. 180) between 1870 and 1914. What is particularly remarked upon is the greater emphasis which was placed on patriotic and imperial themes in schools and youth groups. It is important then to examine this trend, to understand the reasoning and implementation so to be able to make a judgement as to its effectiveness and impact on the young of the day.
When examining the emphasis on patriotic and imperial themes in schools and youth groups it is first important to realize that it is a mistake to treat them as a homogenous whole. Treating Eton or Harrow the same as a school in a working class district of London or any larger industrial city would overlook some important differences in what propaganda was trans­mitted and how it was transmitted. As Mangan (1986, p. 113) points out, until 1902 there were essentially two different education systems, one encompassing the public schools and the other covering the vast majority of children. Only by ac­cepting this fact can we begin to see clearly how and why values were transmitted and make some judgment as to its effect.
This difference can be seen clearly in the question of teaching materials for schools. A lot of focus has been on the introduction of new subjects in schools, especially the humanities, and the textbooks which were designed to teach these subjects. These text books, according to MacKenzie (1984, p. 177) were to instill a certain set of values; patriotism, good citizenship, and moral training. With a contemporary perception of external weakness and greater threat to Britain's position, it was natural to inspire the class of future leaders, through the example of role models who embodied virtuous and moral lives, to be part of the Imperial enterprise.
Clinical Decision Making in Hypotonia and Gross Motor Delay: A Case Report of Type 1 Spinal Muscular Atrophy in an Infant
Authors: Malerba Kirsten Hawkins , Tecklin Jan Stephen 
Published: February 2013

Background and PurposeChildren often are referred for physical therapy with the diagnosis of hypotonia when the definitive cause of hypotonia is unknown. The purpose of this case report is to describe the clinical decision-making process using the Hypothesis-Oriented Algorithm for Clinicians II (HOAC II) for an infant with hypotonia and gross motor delay.Case DescriptionThe patient was a 5-month-old infant who had been evaluated by a neurologist and then referred for physical therapy by his pediatrician. Physical therapist evaluation results and clinical observations of marked hypotonia, significant gross motor delay, tongue fasciculations, feeding difficulties, and respiratory abnormalities prompted necessary referral to specialists. Recognition of developmental, neurologic, and respiratory abnormalities facilitated clinical decision making for determining the appropriate physical therapy plan of care.OutcomesDuring the brief episode of physical therapy care, the patient was referred to a feeding specialist and diagnosed with pharyngeal-phase dysphasia and mild aspiration. Continued global weakness, signs and symptoms of type 1 spinal muscular atrophy (SMA), and concerns about increased work of breathing and respiratory compromise were discussed with the referring physician. After inconclusive laboratory testing for metabolic etiologies of hypotonia, a genetics consult was recommended and confirmed the diagnosis of type 1 SMA at 9 months of age.DiscussionPhysical therapists use clinical decision making to determine whether to treat patients or to refer them to other medical professionals. Accurate and timely referral to appropriate specialists may assist families in obtaining a diagnosis for their child and guide necessary interventions. In the case of type 1 SMA, early diagnosis may affect outcomes and survival rate in this pediatric population.
