Predicting quantum many-body dynamics out of equilibrium
Creators: name: Dabelow, Lennart
Publisher: name: Universität Bielefeld
Year: 2021
Subjects: subject: 530

description: Understanding how the macroscopically observable behavior of systems with many degrees of freedom emerges from the laws governing their microscopic constituents is an intriguing fundamental problem. We approach this issue by investigating how the dynamics of many-body quantum systems is affected by weak-to-moderate perturbations in three different nonequilibrium setups. First, we study the relaxation towards equilibrium under the influence of time-independent perturbations. Second, we consider so-called echo protocols, where the system relaxes for a certain time followed by an effective time reversal during another period of equal duration, spoiled by small inaccuracies in the state at the point of reversal or in the dynamical laws. Third, we analyze the response to external driving in the form of a time-dependent coupling strength for perturbations of a similar kind as in the first setup. These settings cover a large variety of different phenomena and applications such as the relaxation of system-bath compounds, prethermalization, magnetic resonance imaging, quantum quenches, and periodically modulated external fields. Adopting typicality arguments, we derive analytical predictions for the observable dynamics in all three scenarios. Furthermore, we analyze these predictions and verify them by comparison with numerical and experimental data for several different models and observables.
description: Wie sich das makroskopisch beobachtbare Verhalten von Systemen mit vielen Freiheitsgraden aus den Gesetzmäßigkeiten ergibt, die deren mikroskopische Bestandteile beschreiben, ist eine faszinierende grundlegende Fragestellung. Dieser nähern wir uns hier, indem wir in drei verschiedenen Nichtgleichgewichts-Szenarien ergründen, wie sich die Dynamik von Quanten-Vielteilchen-Systemen unter dem Einfluss schwacher Störungen ändert. Erstens untersuchen wir den Effekt von zeitunabhängigen Störungen auf die Relaxation ins Gleichgewicht. Zweitens betrachten wir sogenannte Echo-Protokolle, bei denen ein System für eine gewisse Zeit relaxiert, worauf eine Phase gleicher Länge folgt, während der es sich effektiv in umgekehrter Zeitrichtung entwickelt, wobei jedoch kleine Ungenauigkeiten im Zustand am Umkehrzeitpunkt oder in den dynamischen Eigenschaften auftreten können. Drittens analysieren wir, wie ein gegebenes System auf Störungen ähnlich wie im ersten Fall, jedoch mit zeitlich variabler Intensität reagiert. Diese Szenarien decken eine Vielzahl verschiedener Phänomene und Anwendungen ab, zum Beispiel die Relaxation von zusammengesetzten Systemen mit Wärmebad, Präthermalisierung, Magnetresonanztomografie, schnelle Parameteränderungen (engl."quenches") oder periodisch modulierte externe Felder. Unter Ausnutzung von Typikalitätsargumenten leiten wir in allen drei Fällen analytische Vorhersagen für die beobachtbare Dynamik her. Darüber hinaus analysieren wir diese Vorhersagen und vergleichen sie mit numerischen und experimentellen Daten für verschiedene Modellsysteme und Observablen.

description: Here is a story about a traditional Aboriginal place as told by Elder John Elliott Sr. The place is SNETOED, which means place of blue grouse. SNITCHED2 is on the traditional territories of the WDSANEC peoples who live on what is today called the Saanich Peninsula on southern Vancouver Island, British Columbia. The story represents teachings about rela­tionship that are integral to the WDSANEC culture. The article begins with traditional stories associated with SNJTDED (pronounced Sneet kwulth) before the first contact with Europeans. Five WDSANEC realities about relationship inherent in this story are thankfulness, kindness, helpfulness, respect, and transformation. These teachings come from a healthy and long-lasting relationship with place. The article then tells how SNITCHED was taken by the settlers from the WDSANEC people when they were at their weakest. Finally, the article uses the teachings from this traditional place and shows how these are useful today in reconciling relations be­tween the WDSANEC people, traditional places such as SNITOED, and others who currently live on or use these traditional territories.This is a story about a traditional place on southern Vancouver Island. The place is called SNITCHED in the SENCOTEN language. SNITCHED is an original village site of the WDSANEC people. In a sense, SNITCHED is a womb of WDSANEC people. The first WDSANEC man was put on the earth there by the creator XALS. This first man was named SLDEMEWDD, rain. He was put there on a rainy night to learn how to live in this place.

Inuit Language, Culture, and Parental Engagement in Schooling in One Nunavut Community
Creators: name: Berger, Paul
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: This article explores findings on Inuit parental engagement in schooling drawn frominterviews with 74 Inuit adults and from four months of participant observation inone Nunavut community. It describes the many ways that Inuit parents supporttheir children's learning—ways that are sometimes different from those of astereotypically assertive middle-class Euro-Cananadian parent. It argues that it is amistake for teachers to expect Inuit parents to support schools as EuroCanadianparents might. Instead, to increase parental involvement, Nunavut schools shouldhonor Inuit wishes by bringing Inuit knowledge strongly into schooling. The desirefor more culture, more lnuktitut, and more Elders in schools was passionatelyexpressed by participants who also wanted higher academic standards. Althoughparticipants expressed support for schooling due to its role as a gateway to paidemployment, further support would result from making schooling in Nunavutsupportive of Inuit language and culture.

description: The compounds tris(N-ռ-propyl-3-hydroxy-2-methyl-4-pyridinonato) aluminum(III), -gallium(III), and -indium(III) and tris(N-ռ-butyl-3-hydroxy-2-methyl-4-pyridinonato)aluminum(III), -gallium(III), and -indium(III) were synthesized. All six compounds were prepared via the metal template effect. They were characterized by IR, FAB-MS, ¹H NMR, ²⁷Al NMR, and elemental analysis. Three of the six complexes were studied by single-crystal X-ray diffraction. They formed trihydrates, unlike their N-methyl and N-ethyl analogues, which formed dodecahydrates. The ռ-butyl complex Al(C₁₀H₁₄N0₂)₃‧3H₂0 (1) and ռ-propyl complexes Al(C₉H₁₂N0₂)₃‧3H₂0 [2], and Ga(C₉H₁₂N0₂)₃‧3H₂0 {3} were basically isostructural, crystallizing in the space group P3 with the following crystal parameters for 1, [2], and {3}: α= 15.885 (1) ([15.328 (1)], {15.367 (2)}) Å, c = 7.280 (8) ([7.2321 (2)], {7.256 (2)}) Å, Z = 2. The data were refined by using 1280 ([1377], {1802}) reflections with I>3σ(I) to R and Rա values of 0.047 ([0.057], {0.055)) and 0.061 ([0.077], {0.081}), respectively.

This Is How We "Role": Moving Toward a Cosmogonic Paradigm in Alaska Native Education
Creators: name: Villegas (Alutiiq/Sugpiaq), Malia
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: This article describes the Alaska Native Policy Center's efforts to develop arole-centered conception of educational success that contrasts school- andculture-centered conceptions common in Indigenous education research. Becauserole-centered success hinges on relationality over resources, it makes apparent thedangerous roots of a standards and accountability paradigm. As such, role-centeredsuccess draws on a cosmogonic paradigm that emphasizes relationships in places;over time; and across human, natural, and spiritual realms. Tracing the genealogy ofhigh-stakes testing, the author highlights the limits of a standards and accountabilityparadigm. Further, by presenting a place-based approach to data-collection thatprivileges Native-to-Native comparisons and a brief report of research on AlaskaNative conceptions of success, she explains how role-centered success can informIndigenous education policy and development.

Research that is centered on a community-first perspectivemust be negotiated so as to cultivate respectful, reciprocal, and responsiblerelationships with the community in which the research is situated. The StudentSuccess Research Consortium on Six Nations of the Grand River Territory is aresearch collaboration that seeks to examine ways of defining and supporting studentsuccess from a community perspective. This article explores the emergence ofcommunity-first processes that occurred while the foundation for the educationalresearch was being developed. We discuss the distinctions between community-basedresearch and our approach to community-first research that we describe as land-basedresearch. We also focus on the consideration of Aboriginal ethics from a communityviewpoint, the development of a memorandum of understanding, and the emergenceand implications of ethical space.

Publisher: name: Canadian Journal of Native Education
Year: 2021

description: Indigenous Knowledge (IK) is part of the collective genius of humanity of Indigenouspeoples that exists in the context of their learning and knowing from the places wherethey have lived, hunted, explored, migrated, farmed, raised families, builtcommunities, and survived for centuries despite sustained attacks on the peoples,their languages, and cultures. The primary source of IK is in Indigenous languagesand teachings that make every child unique in his or her learning capacities, learningstyles, and knowledge bases. In IK, learning is viewed as a sacred and holistic, as wellas experiential, purposeful, relational, and a lifelong responsibility. Traditions,ceremonies, and daily observations are all integral parts of the learning process,allowing for spirit-connecting processes to enable the gifts, visions, and spirits toemerge in each person. The best approach to learning and understanding IK is in thedynamic linguistic foundations of Indigenous frameworks and paradigms. Thisarticle, then, seeks to center the intellectual activation of IK by the first generation ofIndigenous scholars, professionals, and activities that have created the Indigenousrenaissance. The article concludes by identifying some current promising practicesthat are seeking to naturalize IK in Canadian education through applications built onrespectful and appropriate strategies.

description: Excerpts from the Preface: At its annual meeting held January 24-27, 1961, the U. S. Department of Agriculture's Tobacco Research and Marketing Advisory Committee recommended that a study be initiated to determine the effect on the cigar industry and tobacco farmers if supplies of Cuban tobacco were no longer available; also, the effect of a change in duty rates. The Committee assigned a high priority to the project. A study group comprised of representatives of several agencies in the Department has devoted as much effort as feasible to this problem over the last several months. An understanding of the problems that would emerge if Cuba were no longer a source of tobacco requires accurate information and statistics on the cigar industry and its market, and on the production and specific use of the many domestic and imported cigar tobaccos. Since there has been a conspicuous lack of some of these important factual materials, it has been necessary for the group to focus its attention on the development of an adequate factual base, and a large portion of this report sets forth the results. In addition, cigar consumption and the total leaf requirements are projected some years into the future; some probable effects if Cuban tobacco became unavailable are discussed. Certain problems touched on in the Committee's recommendations, such as alternative foreign sources and their relation to rates of duty, would require longer range research and additional staff. In preparing this report, the study group sought the advice of representative growers, cigar manufacturers, importers, and dealers. The information and opinions gained in this manner have been highly useful in bringing to light various aspects of the total problem that otherwise might have been neglected.

description: This project aims to alert, raise awareness, research and learn from an environmental protection perspective. The project intends to explore the ecosystems and biodiversity, from the school curriculum of different subject areas (Natural Sciences, Mathematics, Portuguese, Citizenship and Artistic Expressions). This is made through the principles of the scientific method, observation, data collection, experimentation, fieldwork, exchange and communication of ideas, as well as cooperation and partnership with different entities. With this project it is intended to make children observe the surrounding environment, collect information outside the classroom, categorize what they observed and find solutions to real environmental problems. In this way, it is possible to bring students closer to biodiversity issues, such as “Pollination in urban environments”, “Why are there few insects in urban environments?” and "What is the importance of insects for pollination and the balance of ecosystems?".

description: Η μαγνητική ουρογραφία (MRU) θεωρείται ως το επόμενο βήμα στην ουροακτινολογία. Η τεχνική αυτή συνδυάζει ανατομικές εικόνες υψηλής ευκρίνειας καθώς και λειτουργικές πληροφορίες, σε μία εξέταση. Σκοπός αυτής της διατριβής είναι η πραγματοποίηση διαγνωστικών εξετάσεων MRU σε παιδιατρικούς ασθενείς με τον καθορισμό και την βελτιστοποίηση, ενός πρωτοκόλλου, που να μπορεί να παράγει ικανοποιητικές εικόνες MRU, τόσο στατικές όσο και δυναμικές. Τούτο προϋποθέτει την κατάλληλη επιλογή των ακολουθιών και των λήψεων, την ορθότερη προετοιμασία των ασθενών, καθώς και τον κατάλληλο τρόπο και χρόνο χορήγησης του Gd-DTPA. Πραγματοποιήθηκαν MRU σε 21 παιδιατρικούς ασθενείς (3-11 ετών) που εμφάνιζαν σοβαρές συγγενείς διαμαρτίες του ουροποιητικού, μεμονωμένες ή σε συνδυασμό μεταξύ τους. Δημιουργήθηκε ένα τυποποιημένο πρωτόκολλο με σκοπό να εφαρμόζονται εύκολα MRU στην κλινική πράξη. Αποκτήθηκαν Τ1 και Τ2 εικόνες για όλους τους ασθενείς και από τα δυναμικά δεδομένα προέκυψαν καμπύλες έντασης σήματος-χρόνου. Από την κλίση των καμπυλών αυτών προσδιορίστηκαν οι λειτουργικοί νεφροί. Από το σημείο τομής των καμπυλών φλοιού-μυελού προσδιορίστηκαν αποφρακτικά από μη συστήματα. Οι εικόνες και τα δεδομένα που προέκυψαν από τις MRU συμφωνούσαν με τις προηγούμενες διαγνώσεις των 16 από τους 21 ασθενών. Στις υπόλοιπες 5 περιπτώσεις η MRU προσέφερε επιπλέον δεδομένα που άλλαξαν σε μικρό ή και μεγάλο βαθμό τις προηγούμενες διαγνώσεις.
description: Magnetic resonance urography (MRU) is considered as the next step in uroradiology. This technique combines superb anatomical images as well as functional information in a single test. This research aims to implement diagnostic MRUs to pediatric patients in order to determine and optimize a protocol that can produce sufficient MRU images, both static and dynamic. This requires the appropriate choice of sequences and scans, the optimal patient preparation as well as the appropriate way and time of administering Gd-DTPA. MRUs were implemented in 21 pediatric patients (3-11y) that were diagnosed with different types of severe congenital malformations. A standardized protocol was created in order to make MRU feasible in clinical practice. Both T1 and T2 images were obtained for all patients and signal intensity versus time curves arose from the dynamic data. From the slope of these curves the functional kidneys were identified. From the corticomedullary cross-over point obstructed from non-obstructed renal systems were differentiated. The images and data that resulted from the MRUs agreed with the previous diagnosis for 16 out of the 21 patients. For the remaining 5 cases MRU added more information and changed in a small or high degree the previous diagnosis.

description: In recent years, studies and reports by organizations concerned with Aboriginalcommunity and economic development (including government departments,educational institutions, career counselors, and social agencies) have affirmed theimportance of recreation and leisure in Aboriginal community wellness. Another areaof growing interest is the potential economic and social benefit of developing culturaltourism for Aboriginal groups in Alberta. However, in both these related fields, theprovince lacks comprehensive postsecondary education opportunities for leaders andworkers. This article discusses the development of a college-level program inRecreation and Tourism Leadership designed for Aboriginal youth in central Alberta.The planned program emphasizes the integration of learning into the communitythrough innovative delivery systems and flexible accommodation of cultural learningstyles. The article explores program rationales and philosophies, related communityprograms, proposed sociocultural and technological contexts of delivery, and theprocess of consultation with Aboriginal community leaders and educators. Finally, itconsiders the obstacles to program implementation with reference to institutionalconstraints on innovative program delivery in Aboriginal recreation and communitydevelopment training and to indicators of its success in other jurisdictions.

description: A problem was initially identified: the emission of polluting gases into the atmosphere, namely hydrogen sulphide, H2S, by the tanneries close to our school district. After carrying out theoretical investigations in Biology and Chemistry, the students developed an idea for a project, which consisted of creating a biological filter, with a porous matrix that could be easily traversed by the H2S gas, using, for this purpose, the dry fruit of the plant Luffa aegyptiaca. This material possesses a high porosity and good physical and chemical resistance, serving as a support matrix for sulphur bacteria and, initially, also their culture medium. In collaboration with Alcanena's Wastwater Treatment Plant, sludge from different treatment stages containing sulphurous bacteria were collected. These bacteria manage to transform H2S into sulphur and water. Finally, in collaboration with CTIC (Tecnologycal Center for the Leather Industry), iodometric titrations were carried out, proving the effectiveness of the produced filter.

 This species has been recorded from East and Southeast Asian evergreen forests (Guglielmone et al. 2014). It is a parasite of wild pigs (Sus scrofa). Immatures are frequently found on small to medium-sized mammals, especially rodents, with one record from a bird (Kitaoka and Suzuki 1981; Hoogstraal et al. 1986). Dermacentor taiwanensis has rarely been reported from humans (Yano et al. 1993; de la Fuente et al. 2008) and these specimens may have been confused with D. bellulus. Dermacentor taiwanensis has been recorded from Vietnam (Kolonin 1992), but records from peninsular Malaysia (Mariana et al. 2005, 2008a) are considered doubtful due to similarities with the newly redescribed D. bellulus and the newly described D. tamokensis (Apanaskevich and Apanaskevich 2015b, c, 2016).
 Wassef and Hoogstraal (1986a) described the male and female, and Kitaoka and Suzuki (1981) the immature stages. However, the descriptions of the larva and nymph of D. taiwanensis in Kitaoka & Suzuki (1981) are considered to be the first descriptions of the larva and nymph of D. bellulus according to Apanaskevich & Apanaskevich (2015c). Apanaskevich and Apanaskevich (2015b) redescribed the male and female.

Ordering of particulate suspensions in Couette flow at moderate Reynolds numbers
Creators: name: Bell, Martin Derek
Publisher: name: University of British Columbia
Year: 2010

description: A remarkable ordering phenomenon has been seen to occur when a suspension of particles undergoes shear at particle Reynolds numbers of the order of or greater than one in the annular gap of a Couette type shearing device. This particulate ordering was observed and studied with both suspensions of rigid spheres and suspensions of polystyrene latex aggregates formed in the presence of shear within the gap. Each of these systems was studied under a variety of initial conditions in order to define the particular flow conditions required for particle alignment to occur. It was found that particulate ordering occurred under similar conditions to those used by Segré and Silberberg (35) to observe the "necklace formations" that formed within particulate suspensions flowing inside tubes. The separations between aligned particles was found to be strongly dependent on the particle Reynolds number and the ratio between the particle diameter and the width of the annular gap. An insight into the hydrodynamic interactions occurring was provided by the comparisons made between the ordered aggregates and the ordered rigid spheres under similar flow conditions.
New Aboriginal Teachers' Experiences: An Undiscovered Landscape

description: Although teacher preparation, induction, and new teachers' beliefs in mainstreameducation have been the subject of much scholarly investigation, little of this researchhas focused on Aboriginal educators. The preparation and induction of Aboriginaleducators is critical to educational achievement among Aboriginal peoples in Canada.Aboriginal children deserve exemplary and skilled teachers who are responsive totheir individual learning needs and sensitive to the cultural communities to whichthey belong. However, few initiatives address new teachers' experiences that aretargeted at the challenges of being a novice Aboriginal educator. Inadequate attentionhas been given to Aboriginal teachers' perspectives on the educational landscape.

School garden

description: This project began in 2018/2019 due to the interests shown by three classes of the 5th year. Through a brainstorm we realized that the concern about the lack of green spaces was common to several students of the school. Thus, the vegetable garden would make the school greener and more open to the community. The space for construction was chosen and partnerships were created with the department of environmental management and transport of Odivelas (CMO), and the school parents association. We have privileged collaborative and interdisciplinary work to streamline various activities throughout the school year. The study of soil, seeds, autochthonous plants and pollinating insects was done with the help of class teachers and librarian teachers. The days of the native forest and the tree were celebrated with the planting of trees and the holding of a plant fair. At school and throughout the year students disseminated their project through informative posters, school radio and the school's website.
The Values Carry On: Aboriginal Identity Formation of the Urban-Raised Generation

description: In research with urban Aboriginal men from the Toronto area, it was found thatfamilies inherently passed on Indigenous cultural values regardless of how explicitlythe parents taught these values to their children. Aboriginal cultural values areingrained in the families and are passed down such that they may be communicatedand absorbed implicitly. The values of respect, love, autonomy, family, acceptance,ingenuity, and ability to adapt as they are uniquely interpreted in Indigenouscultures were mentioned by the participants as those cherished by their families.Employing a learning circle methodology revealed some of the historical or socialinfluences that affected choices to identify openly as Aboriginal for members ofdiverse generations in the times and places where they lived.

description: As competition over peer status becomes intense during adolescence, some adolescents develop insecure feelings regarding their social standing among their peers (i.e., social status insecurity). These adolescents sometimes use aggression to defend or promote their status. The aim of this study was to examine the relationships among social status insecurity, callous-unemotional (CU) traits, and popularity-motivated aggression and prosocial behaviors among adolescents, while controlling for gender. Another purpose was to examine the potential moderating role of CU traits in these relationships. Participants were 1,047 (49.2% girls; Mage = 12.44 years; age range from 11 to 14 years) in the 7th or 8th grades from a large Midwestern city. They completed questionnaires on social status insecurity, CU traits, and popularity-motivated relational aggression, physical aggression, cyberaggression, and prosocial behaviors. A structural regression model was conducted, with gender as a covariate. The model had adequate fit. Social status insecurity was associated positively with callousness, unemotional, and popularity-motivated aggression and related negatively to popularity-motivated prosocial behaviors. High social status insecurity was related to greater popularity-motivated aggression when adolescents had high callousness traits. The findings have implications for understanding the individual characteristics associated with social status insecurity.

description: A problem of malnutrition has been identified in Mozambique, specifically in Ponta de Ouro Marine Reserve. The project embraces the selection, conservation and preparation of packages of dehydrated vegetables (Corn, cassava, beans, moringa and peanuts), that contain the widest range of nutrients possible, easy to produce and prepare: Xima1 enriched. Thereby, we hope to improve the cognitive, intellectual and motor development of children and the community in general. 1 Xima is a ground corn flour that's turn into a sort of porridge. It is eaten all over sub-Saharan Africa.
History Repeats Itself: Huron Childrearing Attitudes, Eurocentricity, and the Importance of Indigenous World View

description: In an attempt to address the lack of historical research on Native Canadian childrenand Aboriginal forms of learning, this article reports on an investigation into17th-century Huron-Wendat childrearing practices. This study reexamines the few,yet popular interpretations of the Huron childhood experience. Overall, the articleconcludes that contrary to widespread belief, the historical depictions of disrespectand freedom associated with Huron children are false. Accordingly, a new definitionof childrearing practices is contrived exposing their circular and truly complexnature.

Editorial: First Nations' Education at a Critical Juncture

description: The 2006 Canadian Census is now out, and the prognosis for on-reserve Aboriginal education is not good. It shows an ever-widening gap between Aboriginal and non-Aboriginal education success (Richards, 2008).When First Nations assumed "control" of their education processes, it was somehow expected that positive change would occur, bringing suc­cess with fewer dropouts, more fulfillment, higher completion rates, and an education that would meet modern-day demands. In very few situa­tions has this happened, more by accident than by systematic, adminis­trative reform. In more locations than not, First Nations students have became pawns in a complex and troublesome transfer of control. The system has not changed and nor has the curriculum that supported this system. Control has simply meant a delegation of some authority to First Nations and their locally elected or appointed school boards. The very system that failed to deliver relevant and satisfying education off-reserve has now moved on-reserve. But even more significant, the budget and funding that supported First Nations students in off-reserve schools did not transfer with them. First Nations are expected to deliver the same education with a fraction of the funds designated to Aboriginal students who attend provincial schools. This discrepancy has been pointed out in numerous doctoral dissertations (Steinhauer, 2008), in a variety of scholar­ly journals (Wilson, 2007), in national newspaper editorials, and in funded research publications (Mendelson, 2008).

description: Η κριτική στην κοινωνιολογική θεωρία των ρόλων επισημαίνει ως αδυναμία ότι κατασκευάζει ένα υποκείμενο δράσης, το οποίο αποτελείται από ένα άθροισμα ρόλων χωρίς εσωτερική συνοχή. Αφού γίνεται μια κριτική αντιπαράθεση ανάμεσα στη δομική προσέγγιση στην έννοια του ρόλου και στην ιντεραξιονιστική, προβάλλεται ο εαυτός ως διαχειριστής και "ενορχηστρωτής" των διαφόρων ταυτοτήτων ρόλου. Η έρευνα που ακολουθεί ερευνά τη θέση που κατέχει η ταυτότητα ρόλου του εκπαιδευτικού στην αυτοαντίληψή του. Το τελικό συμπέρασμα της εργασίας δείχνει ότι παρά τις αντιξοότητες ο εκπαιδευτικός έχει τοποθετήσει αρκετά ψηλά στην ιεραρχία της κεντρικότητας του την ταυτότητα ρόλου του
description: The critique on sociological theory of roles points out as a weakness that it creates an actor, who is consisted of roles without internal cohesion. After a critical contradistinction betweena the interactionist and structural approach to the concept of role, the self is presented as the coordinator and the "orchestrator" of the role identities. The research that follows deals with the position that teachet role identity has in his/her self-conept. The final conclusion shows that in spite of the difficulties Greek teachers have placed highly their role identity in their hierarchy of centrality

description: Interdisciplinary project, including the school disciplines of Natural Sciences, Mathematics, Expressions, Portuguese, ICT, History and Geography of Portugal. The project emerged from the students' interest and needs when observing the school space. An action plan for the improvement of green spaces was created through the creation of a school garden. The students were involved in planning, creating partnerships, executing and maintaining the project. During the school year, there was a change in behaviour in relation to the garden and the care for the school green spaces by the students involved, but also by the school community.

description: Native peoples in Alaska have usually been the subjects of research rather than thoseresponsible for conducting it. However, the role of Alaska Natives in research ischanging due to a concerted effort on the part of the University of Alaska and Nativepeople themselves to develop new programs aimed at recruiting and preparing Nativescholars in all academic fields who can take on leadership roles and bring anIndigenous perspective to the policy arenas at the local, state, national, andinternational levels. This article describes the activities underway, their rationale,and the implications for research.
