Sydskandinaviska hällristningar har varit av stort intresse för arkeologin under en längre tid. Cirkelmotiv och skepp är några av de vanligaste hällristningsmotiven och detta har resulterat i att en mängd studier har publicerats genom åren. Olika forskare försöker att komma närmare ristningarna på olika plan. Det rör sig om olika symboliska ingångar, men också de mer objektiva ingångarna som datering och utbredningar. Istället för en fördjupning i hällristningarnas betydelser, ägnar sig denna studie åt att studera hur forskningen ser ut inom detta fält. Olika forskares arbeten presenteras vilka skiljer sig i metodiker och teoretiska ingångar. En del är publicerade i fel tid, vilket menas att de avviker från den dåvarande forskningstrenden. Resultatet av det kan variera. En del tenderar att hamna i skuggan av de som följer trenden, men blir relevanta efter sin tid. Studien försöker således att se till vad som händer med forskningen som avviker och även vad de teoretiska ingångarna grundar sig i. / South Scandinavian rock carvings have been of great interest to archaeology for a long time. Circular motifs and ships are some of the most common motifs and this has resulted in a number of studies being published over the years. Different researchers try to get closer to the carvings on different levels. These are various symbolic inputs, but also the more objective inputs such as dating and distributions. Instead of an in-depth look at the meanings of the rock carvings, this study devotes itself to studying what research looks like in this field. The works of various researchers are presented, which differ in methodologies and theoretical inputs. Some are published at the wrong time, which means that they deviate from the current research trend of their time. The result of it may vary. Some tend to be overshadowed by those who follow the trend, but become relevant after their time. The study thus tries to see what happens with the research that deviates and also what the theoretical inputs are based on.

This study used the TIMSS 2011 International Database to investigate predictors of 8th-grade mathematics achievement across three countries that represent a wide range of cultures and levels of mathematics achievement: Chinese Taipei, Ghana, and the United States. A review of literature on predictors of mathematics achievement yielded variables in four major contexts of learning—a student’s home, beliefs, school, and classroom. The variables of home that were investigated are home possessions for learning, parent education, and parents’ expectations and involvement in their children’s education. The variables of student beliefs were self-confidence in mathematics and the value of mathematics. The variables of school were school climate, school resources, administrator leadership, and school socioeconomic status. Finally, the variables of the classroom are access and equity, curriculum, tools and technology, assessment, and teacher professionalism. A 2-level hierarchical linear model was used to investigate relationships between the predictors for learning mathematics and 8th-grade mathematics achievement. Level 1 represented the relationships among the student-level variables, and Level 2 represented the school-level variables. In Chinese Taipei, statistically significant predictors of mathematics achievement in the final model included variables from the domains of home resources, student beliefs, school climate, and school socioeconomic status. In Ghana, both student-beliefs variables had statistically significant relationships with mathematics achievement, and one school climate and one school socioeconomic status variable each was found statistically significant. The U.S. had statistically significant predictors in the domains of home resources, student beliefs, school socioeconomic status, classroom-level access and equity, classroom assessment, and teacher professionalism. This study extends previous research in several ways. It includes a review of classic and recent literature regarding predictors of mathematics achievement; 17 scales using the Rasch partial credit model were developed to measure predictors of mathematics achievement; and the results of this study may be used to examine the relationships between the independent variables of this study and middle-grades mathematics achievement in countries similar to the 3 in this study to reinforce and support variables that contribute to student achievement.

Die weltweite Veränderung der klimatischen Bedingungen macht eine deutliche Verringerung des globalen Ausstoßes von Treibhausgasen unumgänglich. Der Bausektor und insbesondere die Zementherstellung sind von diesen Entwicklungen nicht ausgenommen, weshalb die Suche nach alternativen, nachhaltigen Baumaterialien verstärkt in den Fokus der Industrie und der Wissenschaft rückt. Im vorliegenden Artikel sollen einige Entwicklungstendenzen aufgezeigt und gewisse Potentiale und besondere Eigenschaften dieser Materialien hervorgehoben werden. Dabei erheben die Autoren mit diesem Aufsatz keinesfalls den Anspruch auf eine vollständige Darstellung aller bekannten Optionen, sondern er soll vielmehr zu neuen Denkansätzen motivieren und Forschungsbedarf aufzeigen.

Early voting studies before television predominance determined that mass media had a "limited effect" on American voting behavior. This work reassesses the limited-effects notion. The thesis is that the mass media do have significant impact on voting decisions. A trend study, the work utilizes the Center for Political Studies national presidential election surveys 1952-1976, and multiple regression analysis to examine the impact of media, social, and political variables on the dependent variable, time of voting decision.

The society is becoming more and more dependent on automated solutions. Automation in the transport and logistic sector is accelerating and highly automated trucks, with level four on the SAE scale, are expected to be commercial in the near future. Although it is a common notion that automation leaves humans idle and hence redundant, history proofs the contrary. Technology has always yielded more jobs than it has replaced, though it has resulted in a bigger need for workers to acquire new skills fast. With the development of highly automated trucks, the driver will have the possibility to shift focus from the road during automated driving and hence being able to do other activities. This thesis work has investigated which activities the truck drivers can perform, to create value for the hauliers. It has also investigated what kind of persons that will fit for the changed work tasks. A theoretical study was made where the changing truck industry and humanautomation interaction overall were investigated. Other professions subject to automation in general, and the aerospace and train industry in particular, were also studied in order to forecast how the automation of trucks can affect the role of the driver. An empirical study was made where ten hauliers, four drivers and two pilots were interviewed. Further, a focus group was conducted with six drivers and a survey was sent out to be answered by drivers. The identified value bringing activities were in brief; administrative work, time-saving activities, activities that enhance the drivers' well-being as well as activities of the drivers' own interests. Further, the insights resulted in four personas of potential future truck drivers, which all had different levels of work experience and worked for road carriers that differed in size, from small family business to large international companies. / Samhället blir mer och mer beroende av automatiska system och utvecklingen går snabbt. Inom transportsektorn har utvecklingen av lastbilar med avancerade automatiska funktioner accelererat och lastbilar med nivå fyra på den internationella SAE-skalan beräknas vara ute på marknaden inom en snar framtid. Trots den allmänna uppfattningen om att automatisering av vissa sysslor ersätter människan och lämnar henne sysslolös, så bevisar historien motsatsen. Ny teknik har alltid resulterat i mer jobb än det har ersatt, dock har det ställts högre krav på att människan skall införskaffa sig nya färdigheter snabbt. Genom utvecklingen av lastbilar med avancerade automatiska funktioner så kommer föraren kommer att ha möjligheten att skifta fokus ifrån vägen under automatiserad körning och kommer alltså kunna ägna sig åt annat än att köra. Detta examensarbete har undersökt värdeskapande aktiviteter för åkeriägare, som förare av fjärrbilar kan ägna sig åt under automatiserad körning. Det har också undersökt vilka personer som kommer passa för dem förändrade arbetsuppgifterna. En teoretisk studie genomfördes där den föränderliga lastbilsindustrin samt interaktionen mellan människa och automatisering undersöktes. Vidare undersöktes även andra yrken som påverkats av automatisering, då särskilt tåg- och flygindustrin, för att förutspå hur automatisering av lastbilar kan påverka förarens roll. En empirisk studie genomfördes där tio åkeriägare, fyra förare och två piloter intervjuades. Vidare hölls en fokusgrupp med sex lastbilsförare samt att en enkät skickades ut för att samla in ytterligare uppgifter ifrån lastbilsförare. De identifierade värdeskapande aktiviteterna är i korthet; administrativt arbete, tidssparande aktiviteter, aktiviteter som ökar förarnas välmående samt aktiviteter av förarnas egna intressen. Vidare så resulterade insikterna i fyra persona av potentiella framtida lastbilsförare, som alla hade olika mycket arbetserfarenhet samt arbetade för åkerier som varierade i storlek, ifrån mindre familjeföretag till större internationella företag

Qu’ils en soient les auteurs ou les victimes, les Afro-Américains ont toujours affiché un taux d’homicide largement supérieur à celui des Blancs aux États-Unis. La criminologie a toutefois bien documenté la convergence du taux d’homicide noir vers le taux d’homicide blanc au cours des dernières décennies. À cet effet, il est attesté que le taux d’homicide noir diminue de façon continuelle et de façon plus importante que le taux d’homicide blanc depuis les années 1990. Toutefois, peu de recherches ont examiné la situation depuis 2000. Cette recherche doctorale propose d’analyser la façon dont a évolué l'écart entre le taux d’homicide noir et blanc entre 2000 et 2018 en prenant pour comparaison les deux décennies précédentes. Les résultats permettent de conclure à la fin de la convergence entre taux d’homicide noir et blanc depuis 2000. L’écart entre ces deux taux recommence en effet à se creuser à partir de cette date et se révèle, de surcroît, en moyenne plus élevé que l’écart qui existait entre 1980 et 2000. Ici, une analyse de l'évolution de la part moyenne de foyers noirs et blancs appartenant aux catégories sociales les plus pauvres n’a pas permis d’expliquer de façon certaine cette évolution. Toutefois, l’analyse des écarts de revenus a permis de révéler que les États ayant vu leur ratio d’homicide s’accroître sont souvent les États où les écarts entre la part de foyers pauvres noirs et blancs sont les plus élevés. De fait, l’analyse montre que la situation économique des Noirs s’est dégradée depuis 2000 en comparaison des Blancs, attestant ainsi d’un retour général des inégalités, qu’elles soient criminelles ou économiques, entre Afro-Américains et Blancs depuis 2000. / Whether perpetrators or victims, African Americans have historically had a much higher homicide rate than Whites in the United States. Criminology, however, has well documented the convergence of the black homicide rate to the white homicide rate over the past several decades. To that end, there is evidence that the black homicide rate has been steadily declining by a greater amount than the white homicide rate since the 1990s. However, little research has examined the situation since 2000. This doctoral research proposes to analyze how the gap between the black and white homicide rate has changed between 2000 and 2018 using the previous two decades as a comparison. The results allow us to conclude that the convergence between black and white homicide rates has ended since 2000. The gap between these two rates starts to widen again from this date and is, moreover, on average higher than the gap that existed between 1980 and 2000. Here, an analysis of the evolution of the average share of black and white households belonging to the poorest social categories did not provide a definite explanation for this evolution. However, analysis of income differentials revealed that states with increasing homicide ratios are often the states with the highest differentials in the share of poor black and white households. Indeed, the analysis shows that the economic situation of blacks has worsened since 2000 compared to whites, attesting to a general return of inequality, whether criminal or economic, between African Americans and whites since 2000.

Studien har som syfte att undersöka hur framgångsrika ledare framställs idag och till vilken utsträckning samt i vilka situationer de brukar ett auktoritärt ledarskap. För att uppfylla studiens syfte har dagsaktuella ledarskapstrender samt fiktiva ledare i aktuell populärkultur analyserats genom en kvalitativ innehållsanalys. Resultatet visar att vissa egenskaper är gemensamma hos framgångsrika ledare i såväl trender som hos fiktiva ledare. Det råder delade meningar samt avsaknad av en nyanserad förklaring av vad som är ett auktoritärt ledarskap. Genom att sätta ihop en samlad bild av ett auktoritärt ledarskap går det att urskilja hur vissa situationer efterfrågar och förväntar ett auktoritärt ledarskap. / The purpose of this study is to examine how successful leaders are portrayed today and to what extent as well in which situations they practice authoritarian leadership. To fulfill the purpose of the study have current leadership trends and fictitious leaders in recent popular culture been analyzed through a qualitative content analysis. The results indicate that some characteristics are mutual for successful leaders in trends as well as fictitious leaders. There is a disagreement and a lack of nuanced definition of an authoritarian leadership. Creating a collective definition of an authoritarian leadership makes it possible to discern how certain situations demand and expect authoritarian leadership.
