Planning in Brazil, India and Germany
Planning is a fundamental cognitive ability that helps in organizing and structuring events unfolding in a person\u27s daily life. Two studies are presented that analyze planning behavior in different cultures: Brazil, India, and Germany. The first is a cross-cultural psychological study in which students develop plans for uncertain problem scenarios. The second study follows a cultural psychological tradition. Workers from different domains are interviewed about their life problems and plans. The strengths and the weaknesses of both approaches become obvious in the description and discussion of these two studies. The cross-cultural study sheds light on cross-cultural similarities and differences in planning in Brazil, India, and Germany. The cultural psychological approach yields data regarding a theoretical model on the specific cultural influences on planning
Decision Making in Individualistic and Collectivistic Cultures
How do cultural values influence individuals\u27 decision making? One would expect answers to this question either from cognitive psychology or from cross-cultural psychology. Cognitive theories on decision making, however, rarely consider the factor of culture, and research in cross-cultural psychology deals only to a small extent with decision making. Therefore the study of culture and decision making is a relatively new and unexplored field. In this paper normative and descriptive approaches to decision making are discussed and three cross-cultural studies on decision making in individualistic and collectivist cultures using different methodologies are described. The results are integrated into a model that can be helpful to derive specific hypotheses for further studies in this field
Dominik Tatarka - wędrowiec
Dominik Tatarka is one of the Slovak travel books’s author; he wrotes reports Clovek na cestach. The travelling was important factor of his life: he find an inspiration for his writting and he formulated his life’s philosophy during his journeys. The travelling is one of the important key for reading all his compositions and for understanding his otlook on life: the author presents himself no as the postmodern nomad, but as the pilgrim, who wanders for aim „to unit splits world” and to find a man

Beato Iohannes Traguriensis and Dominik Andreis
In the 17th century, the hagiography and iconography of Bishop Iohannes Traguriensis were enriched by various members of Trogir’ s noble families. In this promotion of the cult of the local beato, Dominik Andreis stands out with his efforts: he was the author of an unpublished Litany in Croatian (1632), the instigator of publishing an Italian Vita by Giovanni Francesco Loredan (1648), and the sponsor of a three act drama by Girolamo Brusoni (1656), performed in Trogir with musical intermezzos and published two years later (1658)
Redifferentiation of dedifferentiated primary chondrocytes in silk-based hydrogels assisted by shockwave treatment
Cartilage is an avascular and aneural tissue, therefore the regeneration potential is limited and neochondrogenesis time-consuming and difficult to achieve. Acute injuries and chronic disorders such as arthritis lead to the degeneration of cartilage, which results in limited mobility accompanied with pain and diminished healing without surgical intervention. Since clinical outcomes for patients have mostly been unsatisfactory in the past, transplantation of tissue engineered cartilage has been introduced as a promising alternative treatment strategy. In this respect, silk-based hydrogels are an interesting biomaterial candidate for cartilage tissue engineering due to their biocompatibility and outstanding mechanical properties. Previously, one of the major bottlenecks of cellular therapies aiming to restore cartilage function through autologous cell/tissue transplantation has been the need for high cell numbers. In particular, reliable culture formats preventing the dedifferentiation of primary cartilage cells (chondrocytes) in response to prolonged culture for in vitro cell expansion have been hardly addressed so far. In this study, we established a protocol for the three-dimensional cultivation and redifferentiation of dedifferentiated chondrocytes over 14 days. This included testing two different strategies to uniformly seed the cells into polymerizing silk hydrogels, a layer-by-layer approach and a direct encapsulation approach. Dedifferentiated chondrocytes were encapsulated in silk-based hydrogels and subjected to extracorporeal shockwave treatment (ESWT) after passage 6 in cell suspension (representing the dedifferentiated state) and/or 24 hours after encapsulation within the hydrogels (marking the begin of redifferentiation). Reverse transcription quantitative polymerase chain reaction (RT qPCR) analysis of collagen type I and II expression levels demonstrated that dedifferentiation of primary chondrocytes in standard monolayer (two-dimensional) culture conditions occurred already after 5 passages. ESWT-treated chondrocytes encapsulated in silk hydrogels showed significantly elevated collagen type II and reduced collagen type I expression levels compared to untreated controls. This is of significance as articular cartilage is defined by a high collagen II/collagen I ratio. Furthermore, western blot analysis demonstrated that, over a culture period of 14 days, chondrogenic redifferentiation occurred, however, no significant difference in protein levels of collagen type I and II was observed between the control and the ESWT-treated groups. Interestingly, the GAG/DNA ratio increased significantly after 14 days when ESWT was applied compared to untreated controls, which correlated with RT-qPCR results. These results were further confirmed by Alcian blue stainings which demonstrated a greater extent of glycosaminoglycan (GAG) secretion after ESWT treatment compared to untreated controls. Additionally, histological stainings showed that, after 14 days of redifferentiation, the secretion of collagen type II was higher in the ESWT group compared to controls, while collagen type I could not be detected. Summarizing, the established method allows homogenous cell distribution within the hydrogels and ESWT promotes chondrogenic redifferentiation without the need for growth factors and/or defined differentiation media. Therefore, this culture system opens the door for a simple method to engineer cartilage-like tissue constructs for use as in vitro tissue models and/or as regenerative tissue transplants.Knorpelgewebe ist avaskulär und aneural, daher besitzt es sehr eingeschränkte Fähigkeiten zur Selbstheilung. Aus diesem Grund kann meist nach einer Verletzung ohne chirurgischen Eingriff keine Besserung erzielt werden, wodurch auf dem Gebiet der Rekonstruktionschirurgie ein sehr hoher Bedarf an Knorpelgewebe besteht. In dieser Hinsicht ist das Transplantieren von knorpelähnlichem Gewebe mit der Hilfe von diversen Biomaterialien als Alternativbehandlung im Bereich Tissue Engineering entstanden. Aufgrund der Biokompatibilität und der einzigartigen mechanischen Eigenschaften haben sich auf Seide basierende Hydrogele als sehr vielversprechend für Knorpelrekonstruktion erwiesen. Ziel dieser Arbeit ist es, eine neue Methode, zur Herstellung von dreidimensionalen auf Seide basierende Hydrogele zu etablieren. Dazu wurden zwei verschiedene Ansätze zur Herstellung entwickelt. Ein System mit drei Schichten und ein weiteres indem das Hydrogel mit demselben Volumen direkt hergestellt wurde. Zusätzlich wurde durch eine Stoßwellentherapie die chondrogene Differenzierung unterstützt. Des Weiteren wird gezeigt, dass primäre Chondrozyten unter Standard 2D-Zellkulturbedingungen spontan dedifferenzieren und nach Einbettung in einer 3D Seidenfibroin-Matrix mit Hilfe der Stoßwellentherapie innerhalb 14 Tagen wieder redifferenzieren. Mittels RT-qPCR Analyse können wir bestätigen, dass die transkriptionelle Aktivität von Kollagen II vor allem in der Stoßwellen Gruppe, verglichen mit der Kontrollgruppe, im innerhalb 14 Tage beträchtlich ansteigt. Dabei war kein signifikanter Unterschied zur Genexpression von Kollagen I zwischen den beiden Gruppen ersichtlich. Dies ist insofern von Bedeutung, da im nativen atikulären Knorpel das Verhältnis von Kollagen II zu Kollagen I sehr hoch ist. Darüber hinaus konnten sowohl mittels GAG-Assay als auch einer histochemischen Färbung die Resultate der RT-qPCR bestätigt werden. Dabei remodellieren die eingebetteten Zellen innerhalb von 14 Tagen die umgebene Matrix zum Teil und Kollagen II, sowie Glykosaminoglykane sekretieren. Hervorzuheben ist, dass bei der Western-Blot Analyse die chondrogene (Re)Differenzierung im Zeitraum von 14 Tagen stattfand, aber, im Vergleich zu den anderen Analyseverfahren, kein signifikanter Unterschied zwischen den beiden Gruppen detektiert werden konnte. Die vorgestellte Methode in dieser Arbeit erlaubt eine homogene Zellverteilung in den Hydrogelen und der Einfluss der Stoßwelle unterstützt die chondrogene Redifferenzierung ohne der Zugabe von differenzierungsstimulierenden Faktoren wie Wachstumsfaktoren oder Ähnlichem. Auch wenn die vorliegende Arbeit das Verständnis von chondrogener Redifferenzierung in tissue-engineertem Knorpel konstrukten erweitert hat, sind weitere Untersuchungen nötig. Dennoch sehen wir dieses Konzept als eine vielversprechende Strategie für Transplantate oder als in vitro Modell von knorpelähnlichem Gewebe.Masterarbeit Wien, FH Technikum Wien 201

Russian Philosophy as interpreted by Dominik Barač
U članku autor prikazuje lik Dominika Barača, dominikanca, filozofa i teologa koji se bavio socijalnom filozofijom boljševizma, odnosno komunizma u Rusiji. Proučava povijesne korijene i uzrok njezina nastajanja, kao i njezin odraz i utjecaj na kršćanstvo. U ruskoj socijalnoj filozofiji boljševizma, koja počiva na ideologiji, totalitarizmu i diktaturi, autor otkriva ideološko-materijalističko ateističko usmjerenje. Kritičkim pristupom ruskoj filozofiji, koja upotrebljava dijalektičko-materijalističko-marksističku metodu, s tomističkog i kršćanskog stajališta uočava teške zablude boljševizma, odnosno komunizma glede poimanja društva u kojemu pojedinac, ljudska osoba, gubi svoju osobnost i dostojanstvo, što je u potpunoj suprotnosti sa socijalno-etičkim principima naučavanja sv. Tome Akvinskoga, skolastičkom filozofijom i kršćanskim naukom.In this article the author gives a portrayal of Dominik Barač - Dominican priest, philosopher and theologian - who was engaged in the study of the social philosophy of Bolshevism, or rather Communism in Russia: its historical roots, the reasons for its emergence and the effect it wrought upon Christianity. The Russian social philosophy of Bolshevism is based on ideological principles, totalitarianism and dictatorship, hence the author unveils its ideological-materialistic-atheistic bent. With a critical approach to Russian philosophy, in which the dialectic-materialistic-marxist method is applied, the author points out from a Thomist and Christian point of view the grave errors of Bolshevism: misconceptions regarding its understanding of a society in which the individual human person in effect loses his individuality and his dignity, this being contrary to the social-ethical principles taught by St. Thomas Aquinas, by the Scholastics and by Christian doctrine
