Arbejdslivets æstetiske tilblivelse: Deleuzianske sange fra anden sal: om småbørnsforældre, multiplicitet, krav, valg, lyst, potentialitet og manøvrering i det moderne arbejdsliv
Get PDFArbejdslivets æstetiske tilblivelse er en analyse af danske småbørnsforældres manøvrering i det moderne arbejdsliv og dets potentialitetsfyldte krydsfelter mellem lyst, krav og valg. Småbørnsforældrene og arbejdslivet analyseres med udgangspunkt i Gilles Deleuzes filosofi og dermed som affektivt performative fænomener, der igennem småbørnsforældrenes forskellige fremgangsmåder skaber værdi i det moderne arbejdsliv på nogle særlige måder. Afhandlingen undersøger derudover, hvordan den moderne småbørnsforældre- og arbejdslivspraksis bliver til gennem småbørnsforældrenes omsætning af mødet mellem krav fra omgivelserne og deres egen lyst, til en praksis, som kan genkendes som værdifuld både på arbejdspladsen, i skoler og dagsinstitutioner og blandt familie, venner og andre med samme sociale interesse på samme tid. Denne del af undersøgelsen er baseret på et feltarbejde sammen med otte småbørnsfamilier. Afhandlingens forskningsfelt er work life balance.
I afhandlingen argumenteres der for det første for, at de valg, som småbørnsforældre træffer, når de manøvrerer i modsatrettede rammer for krav og lyst, er værdiskabende, fordi de bidrager til en opretholdelse og udvikling af det moderne arbejdsliv (Arbejdslivsproduktivitet). Arbejdslivsmanøvreringerne der skaber Arbejdslivsproduktiviteten, som et resultat af kreative tilgange til den potentielle konflikt mellem krav og lyst, bygger alle på en affektdrevet transformation af denne konflikt, som får det som småbørnsforældrene gør til at ligne noget, som, i alle livskontekster, kan genkendes som fornuftig adfærd. Formålet er, udover at imødekomme konflikten, også at give plads til den subjektive lyst, selvom den ikke umiddelbart matcher omgivelsernes krav. Termen Arbejdslivsproduktivitet positionerer Arbejdslivsmanøvrering som en nyttig kompetence hos småbørnsforældre, og er, i det perspektiv, noget som er afledt af småbørnsforældres sociale og kulturelle karakter og deres forventninger til familielivet og arbejdslivet. Ud fra denne læsning bliver succes med småbørnsforældre- og arbejdslivspraktik lig med det moderne arbejdslivs småbørnsforældres samlede mængde af præstation i form af Arbejdslivsmanøvrering.
Det andet argument i afhandlingen vedrører det forhold, at den aktuelle referenceramme for normalitet, som småbørnsforældre og arbejdsliv udspiller sig inden for, i særlig grad, nedprioriterer ideen om forældrenes lyst til at ville deres arbejde på samme niveau eller højere niveau, end de vil deres børn og familieliv. Normalitetsreferencerammen er kendetegnet ved et adfærdskodeks, der udstiller arbejdet som et skyggebegreb, og hvor småbørnsforældre forventes at prioritere deres børn og familieliv højest og handle ud fra de ting, som kravene fra skoler, dagsinstitutioner, medier og børnevelfærdsekspertinstanser peger i retning af. Som arbejdslivsmanøvreringsstrategi er det især udbredt, at skilte forældre optimerer deres arbejdstid i henhold til den samværsfordeling af deres børn, som de har med den anden forælder, med henblik på at arbejde mere end normalt, når de ikke har deres børn hos sig, og arbejde mindre end normalt, når de har børnene hos sig. Formålet er umiddelbart at give plads til, at børnenes velfærd tilgodeses bedst muligt ud fra en antagelse om, at det sker, hvis børnenes tid i skoler og dagsinstitutioner minimeres og forældrene overholder nogle bestemte krav. I det feltarbejde, som afhandlingen trækker på, fremstår det ikke som om, at det udfordrer børnenes velfærd, at de opholder sig på skoler og i institutioner, imens deres forældre er på arbejde. Det fremstår derimod som om, at børnene spejler sig i nogle stærkt etablerede normer, der viser dem, at det er efterstræbelsesværdigt som barn at blive afleveret og hentet efter nogle særlige mønstre, som deres forældre er nødt til at overholde for at familien ikke fremstår som afvigende. Afhandlingen foreslår, at de forenklende og entydige tilgange til småbørnsforældreog arbejdslivspraktik, som er resultatet af den måde som småbørnsforældre- og arbejdslivspraktik reproduceres og bliver til på, erstattes af en mere multifacetteret tilgang til småbørnsforældre og arbejdsliv, der giver plads til et større og mere nuanceret mulighedsrum for både børn og forældre at være mennesker i. På den måde får mennesker mulighed for at reagere på deres familieliv og arbejdsliv på nogle flere forskellige måder.
Afhandlingens tredje argument handler om det metodologiske eksperiment med at studere småbørnsforældre og arbejdsliv ud fra en etnografisk tilgang, som ikke sætter mennesket som genstand for analyse. Denne tilgang kalder afhandlingen for Deleuziansk Etnografi, og denne forskningspraksis præsenteres gennem afhandlingen. I afhandlingen læses forskellige småbørnsforældrearbejdsliv affirmativt med Deleuzes begreb om Folden som tankefigur, gennem scenisk opsatte æstetiske arbejdslivserfaringer, der skaber adgang til at vise småbørnsforældreskabet og arbejdslivets gensidige forbundetheder i affektive sammenstød mellem lyst, krav, valg og potentialitet. Analyserne fokuserer på disse sammenstød og deres performative mekanismer, samt de organiserende og transformative bevægelser ved sammenstødet, i stedet for at fokusere på mennesker og deres forståelser og intentioner. Denne læsning anvendes med henblik på, at gøre forbundethederne klare og kontrollerbare frem for menneskene. Ved hjælp af denne tilgang ønsker afhandlingen at åbne for en anderledes måde at arbejde med og vurdere småbørnsforældre og arbejdsliv – en måde som er følsom overfor forskellige typer af småbørnsforældre samt deres familieliv og arbejdsliv og de performative effekter, som disse faktorer tilsammen skaber i det moderne arbejdsliv
Tales from the pondscape: Living among the ruins of large-scale aquaculture in Tarakan, Indonesia
Get PDFOverall, this dissertation is about what to do when livelihoods disappear and resources run dry. When your shrimp pond yield less and less, when former rich fishing grounds one day are depleted, when the loans on your pond or your boat need repayment and there is no more to sell. The dissertation is based on 11 months of fieldwork in and around Tarakan, the only city in the Indonesian province of North Kalimantan, a center for an extensive aquaculture-industry and a home for thousands of fishermen.
More specifically, the dissertation is about life in and around what I term the pondscape, a 1500 km2 wide area, transformed in the late 90s from mangrove swamps to an endless sprawl of ponds built towards farming tiger shrimp (Penaeus monodon). But the farming of tiger shrimp have started to fail more and more often. Today many, especially older ponds, are abandoned and in spite of new ponds constantly being opened further and further from Tarakan, overall production has stagnated at best. Owners are left indebted and thousands of the sharecropping caretakers in charge of the daily work at the ponds lose their livelihoods. Fishermen living at the periphery of the pondscape started to experience decreasing catches already with the advent of the pondscape, and today most can only keep fishing because of the constantly rising prices of fish.
In the ruined pondscape, bereft of a reliable income, the caretakers left in charge of the failing ponds now rely on collecting mangrove crabs (Scylla spp.) for a living. Endemic to the mangroves that were cleared to make way for the pondscape, these bulky creatures are considered pests to shrimp farming, but can be sold, as they are considered delicacies by many. From warehouses in Tarakan, they are shipped alive across the border to Malaysia in great numbers, and from there to buyers all across the metropoles of South East Asia. This trade is contested though, as the (also most valuable) gravid females are illegal to collect and export, and an array of actors are involved in patrolling the narrow stretch of water separating Tarakan from Malaysia.
The scarcity of fish has led many of the fishermen living at the periphery of the ruined pondscape to change to more intensive trawl gears, originally introduced to catch wild tiger shrimp. This has created tensions with other fishermen who blame trawls for being too destructive. Additionally, the national government did in 2015 reactivate legislation that banned trawl for those very same reasons. In Tarakan however, fishermen organized by middlemen buyers of fish, protested and lobbied successfully against the newly activated laws, leading to a series of exceptions and exemptions being given by local authorities. To this date, an increasing number of Tarakan fishermen use trawl gears, despite them being illegal. All the while, landings continue to dwindle.

In this dissertation, I explore themes of extraction, ruination and connection in the context of a faltering resource frontier of farmed shrimp in Indonesia. Looking back at the economic history of the area, I trace past frontiers and resource booms that have taken place in the area, and which have in various ways paved the way for the present. Amidst this disassembling frontier, past choices restrict the possibilities of the future, and in the lives of the people in the upstream parts of global supply and commodity chains, ruins feature actively. Some enable new frontiers – for a while – while others encourage further destruction in the increasingly futile attempts of securing stable livelihoods.
I argue that the patron-client relationships that for centuries have fueled resource extraction and connected marginal places with global centers have, just as the crumbling physical infrastructure of past frontiers, been incorporated and repurposed in the present. Debt based patronage have proved, on the one hand, to be an efficient way to translate between non-capitalistic modes of production and streamlined global supply chains through outsourcing the violent dispossession and environmental destruction of the frontier to opaque arrangements of debt and despair. On the other hand, old webs of patronage and the possibilities they afford, empower some people on the bottom of the commodity chain, by giving them access to new markets and possibly better futures, if but for a while, as a twilight complex of large-scale economic interests and political interests constantly seek to territorialize any such openings.
The dissertation is an empiric contribution, to a sparse regional literature, but it also adds to the growing multi-disciplinary debates on ecological collapses, environmental ruination and the restricted possibilities and escalating consequences of living with and within accelerating extraction and increasing societal heterogeneity within connection.
Within these debates, the focus on the interplay between capture fisheries and freshwater cultivation is still underexposed, especially when taking into consideration the monumental shifts in the sources of humanity’s consumption of seafood and the destruction being wrought in the process. A destruction taking place as we speak
Analytical Practices in Western Music Theory: A Comparison and Mediation of Schenkerian and Post-Riemannian Traditions
Get PDFThis dissertation is a study of two of the most influential traditions in 20th and 21st-century Western music theory: post-Riemannian function theory and Schenkerian theory, dominating in European and Anglo-American music scholarship, respectively. The purpose is to investigate, chart and provide a path beyond the antagonism that have long existed between these two music-theoretical and ‑analytical traditions. Divided into three main parts, the dissertation aims to achieve this purpose by providing 1) a thorough historical study of the theoretical traditions since Schenker and Riemann (with a special focus on the relatively uncharted territory of post-WWII history); 2) a comparison of theoretical assumptions and analytical practices prevailing in the respective traditions; and 3) a mediation between the two approaches to tonal music in the form of new analytical methods which combine Schenkerian and function-theoretical perspectives

Smag som didaktisk element i stx-gymnasiets faglige samspil: Et effektfuldhedsstudie af dansk- og kemiklassers faglige samspil om, med og for smag
Get PDFAfhandlingen er et empirisk interventionsstudie, som undersøger effektfuldheden af anvendelsen af smag som didaktisk element i stx-gymnasiets faglige samspilsundervisning. Begrebet effektfuldhed dækker i afhandlingen over stx-elevernes bredt definerede udbytte; dvs. tegn på læring samt tegn på faktorer koblet til elevernes læring.
Afhandlingens effektfuldhedsundersøgelse rummer en dobbelt optik. Således undersøges elevernes udbytte dels i relation til afhandlingens fremskrivning af en smagsdidaktisk antagelse om undervisning om, med og for smag i stx-gymnasiets faglige samspil, dels i relation til de lærings- og dannelsesmål, som italesættes på forskellige, diskursive niveauer med gymnasiereformen 2017.
Effektfuldhedsundersøgelsen er udformet som et mixed methods-interventionsstudie, som gør brug af flere kvantitative og kvalitative metoder til indsamling og analyse af data; herunder elev-concept maps, deltagerobservation, elev-survey, elevfokusgruppeinterview, skriftlige elevprodukter samt styredokumenter.
Afhandlingen teoretiske ramme kombinerer sociokulturel læringsteori, kritisk-konstruktiv dannelses- og didaktikteori samt teori om begreberne smag og smagsoplevelse som multisensoriske processer, der involverer den smagendes kemisk-fysiologiske sansninger samt psykisk individuelle og sociale aspekter. Afhandlingens overordnede videnskabsteoretiske ståsted er inspireret af filosofisk hermeneutik
Synergistic hydrothermal liquefaction of waste materials
Get PDFSynthetic polymers constitute one of the largest fractions of solid waste worldwide. From 1950 to 2015, roughly 12 Gton of these materials were deposited either in landfills or in the environment. The absolute majority of these materials are energetically dense, fossil-derived and non-biodegradable, which causes accumulation in the environment, threatening both marine and terrestrial ecosystems. Chemical recycling of these materials can be a management strategy to alleviate pollution and to reuse otherwise wasted energy in the form of solid materials.
Agricultural crop residues are composed of both wet and dry streams, summing up to 3600 Mton year-1 (2013 estimate) of wasted resources globally. Besides that, around 3120 MTon year-1 (2017 estimate) of animal manure is generated worldwide. Nowadays, these agribusiness byproducts are underutilized and their conversion to liquid biofuels may present an untapped opportunity to provide the sustainability needed in sectors dependent on liquid hydrocarbons as an energy source.
This thesis focuses on understanding how synthetic polymers and agricultural waste interact under hydrothermal liquefaction (HTL) conditions, identifying opportunities and evaluating the engineering challenges to apply the technology in combined processing of waste streams. This work evaluates the possibility of recovering monomer-like structures from synergistic combined HTL (co-HTL) of synthetic materials and lignocellulosic biomasses. It also evaluates how biocrudes derived from highly synergistic co-HTL behave in downstream processing for biofuel production when compared to single-feedstock biocrudes.
HTL uses the reactivity of hot-compressed water in near-critical conditions to convert carbon-based materials into useful short chain organic compounds. The interaction of different feedstock materials under this condition allows a beneficial process efficiency and enlarges the opportunities to apply this process in waste handling scenarios.
Literature about HTL processing of synthetic polymers present significant achievements within the field, however the non-standardized approach for several studies lead to contradictory results, generating a knowledge gap between laboratory results and practical applications. Here, results of subcritical HTL processing are presented for the 12 most used synthetic polymers worldwide, both individually and combined with lignocellulosic materials. When evaluating synthetic polymers alone, it is found that materials containing heteroatoms in the backbone of the polymer structure are prone to hydrolysis under subcritical water, while carbon-carbon bonds are preserved. In practice, polymers derived from addition polymerization such as polyolefins and polystyrene do not depolymerize under subcritical water, while condensation polymers and others containing heteroatoms in the backbone are decomposed into molecules similar to their original monomers.
When these materials are combined with lignocellulosic ones, the synthetic parts containing nitrogen heteroatoms tend to synergistically interact with the organic-derived molecules and act synergistically increasing biocrude production. The reactivity of nitrogen species in synthetic polymers was directly proportional to the intensity of the synergies verified. The largest synergy identified was for polyurethane combined processing due to the presence of highly reactive amines bonded to aromatic groups. This finding led to an improved combinedprocessing of polyurethane foam and lignocellulosic materials, reaching pilot processing carbon and energy efficiencies of 71 and 75%, respectively.
The combination of wet and dry agribusiness waste fractions in HTL processing was evaluated using cow manure and wheat straw, respectively, as representatives. Their combination also leads to enhanced biocrude and carbon recovery during subcritical HTL processing through nitrogen species reactions with lignocellulosic-derived compounds. The formation of heteroatom-containing aromatics acts as a carbon carrier to the biocrude products. With this approach, pilot HTL processing carbon yields were enhanced from 40 to 60 wt%, while also providing superior total energy efficiencies (up to 50% based on organic input and output including heating utilities). This increase in carbon efficiency generates further benefits in the production of hydrotreated products, with biomass-to-hydrotreated products carbon balances increasing from 34 wt% for wheat straw in single HTL to 43 wt% in co-HTL of wheat straw and cow manure. The distillation of hydrotreated products depicts that the nitrogen-containing molecules tend to have higher concentration in heavier fractions, which may be an opportunity for more targeted processing of these fractions. Overall, production of biofuels enlarged via co-HTL mainly due to HTL superior carbon and energy yields.
Both synthetic-organic and organic-organic waste combined HTL, the reactions involving nitrogen compounds generate high synergistic effects towards biocrude formation. When increasing product stability through nitrogenated species, a consequent increased difficulty for their removal in following hydrotreatment oil upgrading is also verified. Nevertheless, the enhanced carbon and energy recovery and enlarged scope of HTL technologies attainedvia combination of waste materials is an opportunity to take advantage of these sub-utilized streams.Synthetic polymers constitute one of the largest fractions of solid waste worldwide.

The Affective Overflow of Putting Data to Work : A Study of School Leaders and their Affective Appropriation of Data Instructed to Promote Quality in Education
Get PDFPå mange måder er uddannelsesledelse i dag betinget af et vedholdende politisk krav om at styrke og udvikle kvalitet i bred forstand. I praksis indebærer det, at ledere af uddannelser, især skoleledere, blandt andet bliver afkrævet at bruge data, primært i form af kvantitative målinger af elevers læring og trivsel, som afsæt for det konkrete arbejde med at fremme kvaliteten af netop \u27deres\u27 institution/skole. Set i lyset heraf søger nærværende afhandling at undersøge, hvordan skoleledere faktisk arbejder med data som et led i deres bestræbelser på at tilpasse dette overordnet politiske krav til lokale forhold. Især søger afhandlingen at \u27afdække\u27, hvordan affekt manifesterer sig som en vital del af det at læse, indoptage, bruge og i det hele taget forholde sig ledelsesmæssigt til tal og kvantitative målinger. Målet hermed er kort sagt at skabe viden om, hvorledes spændingsfeltet mellem data, ledelse og affekt udspiller sig i praksis, særligt er fokus rettet mod at \u27afdække\u27, hvordan mere affektive og sanse-informeret \u27orienteringsformer\u27 får betydning for lederes daglige \u27omsætning\u27 af data.
Samlet set peger indsigterne fra afhandlingen på, at arbejdet med data i praksis ikke kun sker på foranledning af ’kølige’ rationelle overvejelser, det sker også på foranledning af mere affekt-informerede eller affekt-mættede måder at mærke og bevæge sig i verden. Med henvisning til disse indsigter argumenterer afhandlingen for, at der er god grund at udvide eksisterende forståelser af, hvad det vil sige at arbejde data-informeret, idet disse forståelser typisk fremskriver det at arbejde med data, som en måde at modvirke eller udgrænse mere affektive, sanse-informeret orienteringsformer. Dertil kommer, at afhandlingen også argumenterer for, at de mere affektive, sanse-informeret måder at forholde sig til data på forskelligvis er med til at give kvalitetsarbejdet ben at gå på. Forstået på den måde, at de er med til at nære det man med inspiration fra Lauren Berlant og hendes arbejde kan kalde for subjekters tilknytning til politiske styreformer og det de lover, og derfor kan de ikke undgå at indvirke på ledernes måde arbejde med kvalitet på, herunder den ildhu hvormed de gør det
Proceedings of the 15th International Conference on Technology in Mathematics Teaching: Making and Strengthening "Connections and Connectivity" for Teaching Mathematics with Technology
Get PDFThe 15th International Conference on Technology in Mathematics Teaching (ICTMT 15) took place on September 13–16, 2022, in the Danish School of Education, Aarhus University, located on campus Emdrup, in the Northwestern district of Copenhagen, Denmark. There were a total of 66 participants from 15 different countries.
ICTMT 15 certainly focused on the impacts that the coronavirus pandemic has had on global mathematics education. However, it looked at the impacts of digital technology from a much wider perspective. In particular, the conference aimed to highlight how technology facilitates the multiple “Connections and Connectivity” between us all to achieve the goals of purposeful mathematics education in the early 21st century.
By “Connections” we mean the interrelationships between researchers, teachers, students, parents, policymakers, and industry (big and small). “Connectivity” includes oral, aural, textual and gestural communications as mediated by the internet, learning environments and classroom activities. Together, “Connections and Connectivity” describes the relationships between people, between different ideas and strategies to teach, and between people and environments. It offers a frame through which to interpret assessment in mathematics education as a more formative process from the point of view of both teachers and students.The 15th International Conference on Technology in Mathematics Teaching (ICTMT 15) took place on September 13–16, 2022, in the Danish School of Education, Aarhus University, located on campus Emdrup, in the Northwestern district of Copenhagen, Denmark.

Proceedings of the 29th EG-ICE International Workshop on Intelligent Computing in Engineering
Get PDFThis publication is the Proceedings of the 29th EG-ICE International Workshop on Intelligent Computing in Engineering from July 6-8, 2022. The EG-ICE International Workshop on Intelligent Computing in Engineering brings together international experts working on the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolution of challenges such as supporting multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research. Competence and knowledge transfer goes both ways.

Matematikhistoriske originalkilder, ræsonnementskompetence og GeoGebra på mellemtrinnet
Get PDFPh.d.-afhandlingen præsenterer forskellige didaktiske principper, der kan understøtte, at elever får mulighed for at udvikle deres ræsonnementskompetence, når de arbejder med samspillet mellem originalkilder og GeoGebra. Ph.d.-afhandlingen tager afsæt i Design Based Research og placerer sig mellem tre forskningsområder: 1) Matematikkens historie, herunder brug af originalkilder, 2) Digitale teknologier i matematikundervisningen og 3) Matematiske ræsonnementer. Den består af tre delundersøgelser: 1) Et review, 2) en analyse af udvalgte kapitler fra et lærebogssystem og 3) planlægning og analyse af tre afprøvninger. Det teoretiske omdrejningspunkt er distinktionerne mellem den undersøgende og produktive side af ræsonnementskompetencen (Niss & Jensen, 2002), epistemisk, pragmatisk og retfærdiggørende medieringer (fx Misfeldt og Jankvist, 2018), regel- og strukturopfattelse samt statisk og dynamisk læsning (Mellin-Olsen, 1984). Derudover inddrages Jensens (2011) beskrivelse af historisk bevidsthed
