Status prawny młodzieżowych rad powiatów
No full textSocial participation, which has its origin in the Constitution of the Republic of Poland (civil society principle), should also be seen on the self-government level. On the county level, citizens’ activity can be strengthened by a youth county council. The article first discusses the history of these bodies as well as their current popularity and condition. The author also tries to create their definition and outline the establishment procedure. While pointing to the legal basis of the establishment acts, the author gives several reasons why youth county councils are not legal in the current circumstances. Youth county councils and youth municipal councils are compared on the basis of their activity. In the final part of the article, the author points out why those bodies should have a legal basis on the national level.Partycypacja społeczna, wynikająca z konstytucyjnej zasady społeczeństwa obywatelskiego, powinna mieć silne oddziaływanie w ramach samorządu terytorialnego. Na poziomie powiatu jedną z form aktywności obywateli może być młodzieżowa rada powiatu. W artykule zarysowano historię tych podmiotów oraz przedstawiono ich obecne rozpowszechnienie. Podjęto próbę stworzenia definicji tych rad oraz omówiono procedury ich powstania. Wskazując na podstawy prawne aktów powołujących, przestawiono wątpliwości co do możliwości ich istnienia w obecnym stanie prawnym. Porównano także aktywność tych podmiotów i młodzieżowych rad gmin, posiadających umocowanie ustawowe. Na podstawie oceny działalności młodzieżowych rad powiatów zaprezentowano również powody, które przemawiają zdaniem autora za koniecznością nowelizacji ustawy o samorządzie powiatowym
Shape Sensing of Hyper-Redundant Robots Using an AHRS IMU Sensor Network
No full textThe paper proposes a novel approach for shape sensing of hyper-redundant robots based on an AHRS IMU sensor network embedded into the structure of the robot. The proposed approach uses the data from the sensor network to directly calculate the kinematic parameters of the robot in modules operational space reducing thus the computational time and facilitating implementation of advanced real-time feedback system for shape sensing. In the paper the method is applied for shape sensing and pose estimation of an articulated joint-based hyper-redundant robot with identical 2-DoF modules serially connected. Using a testing method based on HIL techniques the authors validate the computed kinematic model and the computed shape of the robot prototype. A second testing method is used to validate the end effector pose using an external sensory system. The experimental results obtained demonstrate the feasibility of using this type of sensor network and the effectiveness of the proposed shape sensing approach for hyper-redundant robots
Numerical Shape Planning Algorithm for Hyper-Redundant Robots Based on Discrete Bézier Curve Fitting
No full textThe paper proposes a novel numerical method S-GUIDE that provides real-time planning of the shape of hyper-redundant robots with serial architecture by means of a guidance curve, represented in parametrized analytical form and in numerical form by a set of key points associated with the robot structure. To model the shape of the robot, the method uses an equivalent model, and a shape guidance curve obtained through a controlled adjustment of a Bézier curve. This is achieved in three computing steps were the robot equivalent structure, it’s associated kinematic parameters and the robot actuation parameters in joint space are calculated. The proposed method offers several advantages in relation with the precision, computing time and the feasibility for real-time applications. In the paper, the method accuracy, execution time, and the absolute error for different work scenarios are determined, compared and validated

Data-Driven Kinematic Model of PneuNets Bending Actuators for Soft Grasping Tasks
No full textThe paper proposes a novel data-driven approximation kinematic (DAK) model to estimate the shape and opening level of a PneuNets soft gripper in relation to the applied pressure signal. The model offers suitable capabilities for implementing in real-time applications involving soft grasping planning and size recognition of fragile objects with different sizes and shapes. The proposed DAK model estimates the free bending behavior of a PneuNets actuator (soft gripper finger) based on a set of approximation functions derived from experimental data and an equivalent serial mechanism that mimics the shape of the actuator. The model was tested for a commercial PneuNets actuator with decreasing chamber height, produced by SoftGripping Co. (Hamburg, Germany). The model validation is accomplished through a set of experiments, where the shape and elementary displacements were measured using a digital image processing technique. The experimental data and the estimated data from the DAK model were compared and analyzed, respectively. The proposed approach has applicability in sensorless/self-sensing bending control algorithms of PneuNets actuators and in soft grasping applications where the robotic system must estimate the opening level of the gripper in order to be able to accomplish its task
Rad GTPase inhibits cardiac fibrosis through connective tissue growth factor
No full textAims Our previous studies documented that Rad (Ras associated with diabetes), a member of the RGK (Rad, Gem, and Kir) family of Ras-related small G protein, is significantly decreased in human failing hearts and plays an important role in attenuating cardiac hypertrophy. The goal of this study is to identify the effect of Rad on cardiac fibrosis and the underlying mechanisms. Methods and results Rad knockout (KO) mice showed more severe cardiac fibrosis compared with wild-type littermate controls as detected by Sirius Red staining. Western blot analyses demonstrated that the expression of connective tissue growth factor (CTGF), a key mediator of fibrosis, increased dramatically in Rad KO mice. Overexpression of Rad in cultured neonatal cardiomyocytes suppressed both basal and transforming growth factor-beta 1-induced CTGF expression. Elevated CTGF expression was observed in cardiomyocytes when Rad was reduced by RNA interference. Moreover, cardiac fibroblasts produced greater extracellular matrix (ECM) when stimulated with conditioned medium from Rad-knockdown cardiomyocytes. ECM production was completely abolished by adding a CTGF-neutralizing antibody into the medium. CCAAT/enhancer-binding protein delta(C/EBP-delta) was demonstrated to activate CTGF in cardiomyocytes. Chromatin immunoprecipitation assay and co-immunoprecipitation further demonstrated that Rad inhibited the binding of C/EBP-delta to the CTGF promoter via direct interaction with C/EBP-delta. Conclusion Our data reveal that Rad deficiency can lead to cardiac fibrosis. Rad inhibits CTGF expression through binding with C/EBP-delta, thus regulating ECM production in the heart. This study suggests a potential link between decreased Rad levels and increased cardiac fibrosis in human failing hearts.Cardiac & Cardiovascular SystemsSCI(E)PubMed13ARTICLE190-989
Platelet-derived growth factor induces Rad expression through Egr-1 in vascular smooth muscle cells.
No full textBACKGROUND: Ras associated with diabetes (Rad) inhibits vascular lesion formation by reducing the attachment and migration of vascular smooth muscle cells (VSMCs). However, the transcriptional regulation of Rad in VSMCs is unclear. METHODOLOGY AND PRINCIPAL FINDINGS: We found that Platelet-Derived Growth Factor (PDGF)induced Rad expression in a time- and dose-dependent manner in rat aortic smooth muscle cells (RASMCs) using quantitative real-time PCR. By serial deletion analysis of the Rad promoter, we identified that two GC-rich early growth response-1 (Egr-1) binding sites are essential for PDGF-induced Rad promoter activation. Overexpression of Egr-1 in RASMCs strongly stimulated Rad expression while the Egr-1 corepressor, NGFI-A binding protein 2 (NAB2), repressed PDGF-induced Rad up-regulation in a dose-dependent manner. Direct binding of Egr-1 to the Rad promoter region was further confirmed by chromatin immunoprecipitation assays. CONCLUSIONS: Our results demonstrate that Rad is regulated by PDGF through the transcriptional factor Egr-1 in RASMCs
Hochbegabte kinder - das unterdrückte genie -- was treibt Hans Giebenrath unter das rad?: eine neuere perspektive zu Herman Hesses Unterm Rad, in bezug auf die idee ,das lernen als strafe'
No full text2013 Fall.Includes bibliographical references.Text in German; title and abstract in English and German.The current discussion on Hermann Hesse's 1906 book, Unterm Rad, leaves many open-ended questions. Because the storyline so closely follows Hermann Hesse's personal biography, it obfuscates his authorial intentions and makes it difficult for scholars to differentiate between the two. Many critics also claim that the correlations between Unterm Rad's protagonist, Hans Giebenrath, and Hesse's personal life have actually stagnated later research about the book, as discussions always circle back to Hesse's personal struggles in the Prussian school system. This thesis, although acknowledging the similarities to Hesse's personal timeline, aims to frame the book in historical context in order to discuss its importance in a literary context. This thesis begins by analyzing the norm of educational methods in the early nineteenth century, and establishes that they are strongly based on a long tradition of child rearing by using force. This can be traced back to some accounts from 1752, and are based on a history of bourgeois childrearing. The headmaster and pastor's treatment of Hans in Unterm Rad clearly demonstrate the force and suppression of new ideas, used as modes of teaching to ensure students conformed to societal norms: this is historically reconcilable. Hesse's fictional story is thus the ideal basis for an analysis of childrearing methods used during that time. In order to effectively introduce a new perspective on the discussion, this paper uses the New Historicism approach and begins with Roland Barthes's theory of authorial intention. It analyses the text within the constraints of The Death of the Author, and continues with Michel Foucault's What is an Author? The goal is to evaluate what Unterm Rad says about the child rearing at the turn of the century in southern Germany, particularly for gifted children, and how it can be applied to what is already known from a historical standpoint. This idea is then applied from Hans Giebenrath's point of view to German psychologist Katharina Rutschky's concept of "Schwarze Pädagogik" or "Black Pedagogy" and her theories of suppression. This idea is further supplemented by Alice Millers research on childrearing, in relation to Hans's experience at the school in Maulbronn
Role rad społecznych we współrządzeniu miastem
No full textUrban governance (UG) is a place-based network of cooperation between public and non-public actors where public authorities play a strategic role in deciding on city matters. A number of UG actors include advisory councils (ACs), characterized by a long tradition, universality, stability and objectives related to urban affairs. The article aims to identify AC roles in UG. In addition, the author hypothesizes a correlation between the number of official (statutory) and informal (not legally regulated) roles and differences between ACs in terms of the roles they play. The hypotheses were verified in qualitative research. 57 semi-structured interviews were conducted with members of the youth councils, senior citizen councils, sport councils, and councils for residents with disabilities in 16 Polish cities. The interview transcripts were uploaded to QDA Miner for encoding and analysis. It was found that all ACs, regardless of their official roles, play informal roles, and all these roles are related to UG. There is no correlation between the number of official and informal roles, which would make ACs very similar unless the mandatory character of the roles played by the council for residents with disabilities, which differs this AC from the other. The results of the study lead the author to recommend revisions to AC regulations in order to increase their participation in the UG.Współrządzenie miastem (WM) to związana z miejscem sieć współpracy między podmiotami publicznymi i niepublicznymi, w której władze publiczne odgrywają strategiczną rolę w podejmowaniu decyzji o sprawach miasta. Wśród aktorów WM są rady społeczne (RS), które charakteryzują się długą tradycją, powszechnością, stabilnością i celami związanymi z miastem. Artykuł ma na celu identyfikację ról RS w WM. Ponadto autorka stawia hipotezę o związku między liczbą ról oficjalnych (ustawowych) i nieformalnych (nieuregulowanych prawnie) oraz o różnicach między RS pod względem pełnionych ról. Hipotezy zweryfikowano w badaniach jakościowych. Przeprowadzono 57 wywiadów częściowo ustrukturyzowanych z członkami rad młodzieżowych, rad seniorów, rad sportu i rad ds. osób niepełnosprawnych w 16 polskich miastach. Transkrypcje wywiadów zostały wprowadzone do QDA Miner w celu zakodowania i analizy. Stwierdzono, że wszystkie RS, niezależnie od swoich ról oficjalnych, pełnią role nieformalne, a wszystkie te role są związane z WM. Nie ma związku między liczbą ról oficjalnych i nieformalnych, co sprawia, że RS wydałyby się bardzo podobne, gdyby nie role pełnione przez radę ds. osób niepełnosprawnych, które mają charakter obowiązku ustawowego, co istotnie różni tę radę od pozostałych. Wyniki badań skłoniły autorkę do zaproponowania zmian w przepisach dotyczących RS w kierunku zwiększenia ich udziału w UG
