"To publish art – to literally make it public – was a political act, one that challenged the art world and the world at large" (Gwen Allen). This critical appraisal on the published journal Next Level reports the result of my research relating to the body of my work from 2005 to 2016. More specifically, I will survey the creative production of the contemporary photography journal Next Level, currently consisting of seven city editions from a volume of twenty-four editions. This acknowledgement is not intended to emphasise the subjectivity of the journal as a limitation, but rather to provide focus to the lens through which I have been looking at my data with important findings about the outcomes of measurable theoretical, critical and artistic approaches. The journal Next Level periodically publishes a number of editions that present the collection of original data about photography art communities through the exploration of various cities around the world. These editions are developed from data collected through on-the-ground research that is central to this evaluation, which is an examination of and response to a large range of data drawn from seven cities, providing new information. This provides a pivot for the work around which my ideas are put across in a meaningful, comparable and communicable way, creating a mapping of each city, always enabling and never limiting. This methodology of gathering data, consisting of governmental cultural reports, museum archives, catalogues, comment books and newsletters, visual artists’ curriculum vitaes (CVs), interviews and rich contextual material, in turn provides primary research for students, photography professionals, photography enthusiasts and future photography historians. By countering the standard framework of research and production, my work is theoretically, critically and artistically traced, not by making things new, but by comprehensively questioning the characteristics that have shaped things in new ways. This framework manifests itself in the preliminary research and creative practice that provided the foundation for the complete scope of the entire space in the journal, which I present alongside this critical appraisal. Through the dissemination of current photographic discourse, I discuss current traditions and new perceptions through various articles and features. These editorial pieces relating to local communities of contemporary art photography look in particular at their cultural outputs in response to the rise of globalisation. Through the roles of artist-as-editor and curator, the journal is an artefact that I have shaped, utilising print production as part of its aesthetic dimension. I have published and distributed between 8,000 and 20,000 copies per edition to 37 countries. The readership of the journal thus has access to viewpoints that are revealing and politically reflective of specific manifestations of power, representation and the unheard stories that are altering various aspects of the conventions of current photographic discourse.

Det här är en systematisk litteraturstudie med inriktning mot skolans lägre åldrar. Studiens syfte är att undersöka vilka svårigheter eleverna möter när de arbetar med området bråk i matematiken. Vidare syftar den även till att synliggöra var i förflyttningen från ett konkret till ett abstrakt arbetssätt det är som svårigheterna främst uppstår. För att svara på studiens syfte och frågeställningar grundar sig studien i flertalet vetenskapliga publikationer. Resultatet av studien synliggör flertalet svårigheter eleverna möter, samt att det finns en variation angående var i förflyttelsen de uppstår. Utifrån resultatet är det främst i ett visst stadie svårigheterna uppstår, dock beskrivs det vidare att det inte alltid är där som svårigheterna synliggörs. Studien redovisar även lärarens betydande roll för att eleverna ska bli motiverade och finna mening med sin bråkräkning.

The study to be reported was designed to investigate the effects of verbal praise and reproof, from persons in authority, on the LOA and subsequent performance of institutionalized defectives.

Relative sea level (RSL) reconstructions from paleo records are often the most valuable data set in testing and constraining glacial isostatic adjustment (GIA) models. In some regions, the amplitude and rate of the reconstructed RSL changes are large making the data difficult to fit. Arguably, the reconstructed RSL curve from Maine, USA, is the classic example of such a data set with peak values at about 120 m dropping to a low stand of around -40 m within a few kyr. To our knowledge, no GIA model has captured these extreme variations and the record has been somewhat neglected by the GIA community. Here we critically assess and present a revised pre-10 ka RSL data base for this region and combine it with two recent Holocene compilations. To determine if a successful model fit can be found, output based on a parameter set of five ice models and 440, spherically-symmetric, Maxwell Earth viscosity models was compared to the compiled data. Results show that none of the ice models produce a good fit for the large suite of 1D viscosity models considered. Specifically, the modelled timing and rate of RSL fall are generally too early and low, and the RSL low stand from the models is significantly higher than that observed. A model sensitivity analysis suggests that Earth models that can simulate time-dependent viscosity (e.g., those including transient and/or non-linear effects) are required to fit the Maine RSL data set.

This dissertation study, which comprises a series of three articles, addresses the following overarching research questions: 1. How have reading motivation and engagement been conceptualized in the research literature? 2. How do educators, particularly teachers of the primary grades, conceptualize reading motivation and engagement? What sources of information do they draw upon to construct their understandings? 3. How do educators, particularly teachers of the primary grades, enact literacy instruction in support of student motivation and engagement? In the first article, I explore different theoretical approaches to the study of reading motivation and engagement through the creation of a continuum model of the extant literature. I advance an approach to the study of reading engagement that is primarily sociocultural, while also drawing on insights from research that is more cognitive in orientation. To accompany that approach, I present a new definition of reading engagement that draws on insights from various theoretical traditions. In the second article, I consider how 31 first-grade teachers at public schools in the Midwest and Northeast who were involved in focus groups to imagine what it might be like to implement project-based learning in their settings conceptualized students’ motivation for and engagement in literacy under the imagined curriculum. The analysis balances an approach in which the concepts from the extant literature are applied directly to participants’ comments with an actor-oriented approach (Penuel, Phillips, & Harris, 2014) that privileges practitioners’ perspectives and considers what participating practitioners were attending to in articulating their understandings. I explore in depth the complexities around the social and cultural dimensions of engagement experienced by participating teachers, and how they made sense of those complexities. Finally, in the third article I offer a case study of how two third grade teachers at an urban, public charter school conceptualized reading motivation and engagement, including what sources of information they drew upon to construct those conceptualizations, as well as what those teachers actually did in their instruction to support and promote students’ engagement in reading. Findings indicated that, while both teachers conceptualized engagement as social, the ways in which they enacted that understanding varied based on the principles around which they organized their literacy instruction. At the conclusion of each article and at the end of the dissertation as a whole, I discuss implications for research and for practice, including teacher education and professional development.

Studien gjordes i syfte att besvara huruvida färgskillnad, kontrastskillnad eller en kombination av dessa var avgörande i att vägleda spelare i förstapersonsspel. Enligt hur kompositionstekniker fungerar och används inom grafiskt arbete skapades en hypotes och en tillhörande nollhypotes. Dessa prövades genom frekvensfördelning och univariat analys efter en artefakt testats.  Denna artefakt var i form av en spelbar bana som producerades med varierande uppsättningar av ljusstyrkor och färg, kallat attraheringsmetoder. Denna bana hade då flera tvåvägskorridorsval där en väg på förhand hade definierats som ”den korrekta vägen” och det var längs denna väg som en attraheringsmetod t.ex. ett starkare ljus placerades. Data samlades in genom öppet deltagande observation samt inspelning av aktiviteten på datorn. Efter banan spelats igenom hölls även ett kvalitativt moment i form av en intervju med syfte att etablera vilka faktorer som informanten trodde påverkat dennes vägval samt om de var medvetna om vilken väg de tagit. Det studien slutligen kom fram till var att spelare oftast tenderar att följa vägar som har starkare ljus. Ibland följs även vägar utav en utstickande färg men oftast följs en starkt upplyst väg. Både hypotesen och nollhypotesen är därmed falsifierad och den undersökta frågan kan besvaras med att skillnader i kontrast är det som i flest fall tenderar att vägleda spelare i ett förstapersonsspel.

Resonators are one of the most important parts of electronic products. They provide a stable reference frequency to ensure the operation of these products. Recently, the electronic products have the trend of miniaturization, which rendered the size reduction of the resonators as well [1]. Better design of the resonators relies on a better understanding of the crystals' nonlinear behavior [2]. The nonlinearities affect the quality factor and acoustic behavior of MEMS (Micro-Electro-Mechanical-System) and nano-structured resonators and filters [3]. Among these nonlinear effects, Drivel Level Dependence (DLD), which describes the instability of the resonator frequency due to voltage level and/or power density, is an urgent problem for miniaturized resonators [2]. Langasite and GaPO4 are new promising piezoelectric material. Resonators made from these new materials have superior performance such as good frequency-temperature characteristics, and low acoustic loss [2]. In this thesis, experimental measurements of drive level dependence of langasite resonators with different configurations (plano-plano, single bevel, and double bevel) are reported. The drive level dependence of GaPO4 resonators are reported as well for the purpose of comparison. The results show that the resonator configuration affects the DLD of the langasite resonator. Experiments for DLD at elevated temperature are also performed, and it was found that the temperature also affects the DLD of the langasite resonator.
