Tibetan Cultural Identity in Nepal: Change, Preservation, Prospects
2016
In the difficult circumstances of institutional discrimination and political pressure, the Tibetan minority in Nepal negotiate their identity with utmost communicative resourcefulness, tying their values to universal ethics. They resort to their spiritual heritage in their daily intercultural encounters, seeing it mostly as an essential mindset. Developing intercultural personhood through universalization does not challenge identity salience, if one’s culture is adhered to consciously. The respondents are optimistic about preserving their culture, provided the positive factors, such as community living and cultural education, persist. The obstacles are seen in materialistic influences, glob…
Face-work in teacher-in-role: Acting at the interface between artistry and pedagogy
2016
The teacher-in-role (TIR) strategy is used in process drama to strengthen the dramatic experience and promote learning among the participants. In this study, one TIR construct is examined through the lens of Erving Goffman’s concept of facework in order to deepen the understanding of the subtle and vulnerable processes of interaction in process drama. TIR is considered to be an interactive construct in which both artistry and pedagogy are embodied. Face-work is applied in the fictive context of process drama to uncover the interactional potential for learning and creating drama. In addition, the teacher’s reflections on his or her actions as they relate to face-work in process drama are exp…
Adolescent coping with everyday stressors: A seven-nation study of youth from central, eastern, southern, and northern Europe
2007
The present study compares problem-specific coping strategies and coping styles of European adolescents from seven nations. The sample consisted of 3031 adolescent participants, aged 11 to 20, from Croatia, the Czech Republic, Germany, Italy, Norway, Portugal, and Switzerland. The adolescents completed the Coping Across Situations Questionnaire (CASQ) by indicating which coping strategies (from 20 alternatives) they usually employed in dealing with age-specific problems (covering 8 different domains). The strategies can be collapsed to three coping styles: active coping, internal coping, and withdrawal. Results show that adolescents from all seven nations predominantly employed functional f…
The occurrence of serological H-Y antigen (Sxs antigen) in the diandric protogynous wrasse, Coris julis (L.) (Labridae, Teleostei)
1987
Abstract The serological sex-specific (Sxs) antigen (previously called ‘H-Y antigen’) has been shown, in various vertebrate species ranging from fish to mammals, to be characteristic of the heterogametic sex. We studied a protogynous hermaphrodite, Coris julis , in order to examine whether the change of a female to a secondary male also involves a change in the Sxs-antigen phenotype. The (homogametic) females of this species were found to be Sxs negative, while both primary and secondary males were Sxs positive. This was true not only for gonads but also for nongo-nadal tissues. The administration of androgen to females is known to cause sex inversion in this species; we were able to demons…
Scattering lengths and universality in superdiffusive L\'evy materials
2012
We study the effects of scattering lengths on L\'evy walks in quenched one-dimensional random and fractal quasi-lattices, with scatterers spaced according to a long-tailed distribution. By analyzing the scaling properties of the random-walk probability distribution, we show that the effect of the varying scattering length can be reabsorbed in the multiplicative coefficient of the scaling length. This leads to a superscaling behavior, where the dynamical exponents and also the scaling functions do not depend on the value of the scattering length. Within the scaling framework, we obtain an exact expression for the multiplicative coefficient as a function of the scattering length both in the a…
Ultrafast Optical Demagnetization manipulates Nanoscale Spin Structure in Domain Walls
2012
During ultrafast demagnetization of a magnetically ordered solid, angular momentum has to be transferred between the spins, electrons, and phonons in the system on femto- and picosecond timescales. Although the intrinsic spin-transfer mechanisms are intensely debated, additional extrinsic mechanisms arising due to nanoscale heterogeneity have only recently entered the discussion. Here we use femtosecond X-ray pulses from a free-electron laser to study thin film samples with magnetic domain patterns. We observe an infrared-pump-induced change of the spin structure within the domain walls on the sub-picosecond timescale. This domain-topography-dependent contribution connects the intrinsic dem…
Reverse-Safe Text Indexing
2021
We introduce the notion of reverse-safe data structures. These are data structures that prevent the reconstruction of the data they encode (i.e., they cannot be easily reversed). A data structure D is called z - reverse-safe when there exist at least z datasets with the same set of answers as the ones stored by D . The main challenge is to ensure that D stores as many answers to useful queries as possible, is constructed efficiently, and has size close to the size of the original dataset it encodes. Given a text of length n and an integer z , we propose an algorithm that constructs a z -reverse-safe data structure ( z -RSDS) that has size O(n) and answers decision and counting pattern matc…
Simulazione del deflusso laterale saturo, dei livelli di falda e dell'umidità del suolo alla scala di versante
2018
La corretta rappresentazione dei processi idrologici alla scala di versante è fon-damentale per la simulazione della risposta idrologica dei bacini idrografici durante eventi di pioggia intensa. I modelli basati sulla risoluzione dell’equazione di Richards possono simulare efficacemente le dinamiche della zona satura e non satura del suolo. Tuttavia essi richiedono una parametrizzazione onerosa, difficile da rilevare sperimentalmente sopratutto su ampie scale spaziali di applicazione. In questo lavoro di ricerca è stato sviluppato un modello idrologico monodimensionale di versante, in cui i processi di flusso laterale di falda sono rappresentati attraverso l’equazione di Darcy, mentre sono …
