The transition from unicellular to multicellular life remains one of evolution’s biggest mysteries. In this study we introduce symbioses with bacteria as a possible player. We use metagenomic analysis to investigate bacterial communities associated with Volvocine green algae, a model system for multicellularity. We compared bacterial communities of 34 algal species (21 unicellular and 13 multicell

Purpose: Investigate how the corporate brand can play a strategic role within the cargo port industry through affecting the choice of cargo port from the customer’s perspective. Methodology: A qualitative method with an abductive approach has been used. The research design is based on semi-structured interviews. Theoretical approach: The theoretical foundation complies theory from the strategic

Local governments in Sweden live in a reality where the European Union has an increased impact on them, via legislation, policy making, EU-funding programs etc. This thesis focuses on local governments’ responses towards European integration. It does so by using elements of the theory of fusion – the fusing of institutional levels creates a world where the EU is the policy initiator, national gove

Weight of evidence (WOE) transformation has been used for several decades in the credit industry. However, despite its widespread use, it has, surprisingly, been an overlooked approach in published literature. In this paper, we, therefore, investigate what effect WOE transformation has on the discriminatory power of a credit-scoring model. Our results suggest that using WOE transformation with log

The construction industry is expected to generate 2.2 billion tons of waste by the year 2025 and was responsible for 39 % of GHG emissions generated by the building processes and energy consumption, in 2017. In 2018, the Swedish construction industry accounted for 21 % of the total GHG emissions (including imported emissions) and 35 % of the total amount of waste in the country. In these past deca

Populärvetenskaplig sammanfattning Långsiktig morfologisk utveckling av Cua Lo mynning i centrala Vietnam - En processbaserad numerisk modellering Nikita Tegenfeldt Orio Johansson En matematisk modell utvecklades för att beskriva hur en flodmynning i centrala Vietnam kommer att flytta sig längs med kusten och hur bredden förändras från nu fram till 2050. Mynningen kopplar ihop havet med en lagCua Lo river mouth is a coastal inlet connected to an estuary at the central coast of Vietnam. The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. In connection to the inlet lies an elongating sand spit which causes erosion and destruction of residential areas on one side of the

This longitudinal observational study aimed to determine if ventricular dimensions of the athlete's heart remain balanced and proportional to peak oxygen uptake (VO2peak) following long-term deconditioning in elite athletes. Fourteen mixed-type male athletes (7 soccer, 7 handball players) were prospectively evaluated with cardiac magnetic resonance imaging and cardiopulmonary exercise testing whil

A growing body of correlational studies suggests that sex hormones such as those contained in, or affected by, oral contraceptives (OCs) may impact economic behavior. However, despite widespread use of OCs among women in Western countries, little is known about their potential behavioral effects. The present study investigates whether OCs causally influence economic preferences. We randomly alloca

This study analyzes how Danish policies aiming at active labour market participation aggravate the social exclusion of non-western immigrants. The study points out the necessity of investigating the success of active labour market policies not only through focusing on reduction in the number of unemployed immigrants, but also whether they alleviate social exclusion as claimed by Danish authorities

Popular Abstract in English The eye is a complex device in charge of producing clear and sharp images of the outside world. While some people need glasses early on in their lives, others have nearly perfect vision until, all of a sudden, they have to hold books or documents further and further away from their eyes to be able to read them and eventually have to resort to reading glasses. This visuaHealthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. The aim of this thesis is to elucidate the molecular origin of the gradual hardening of the c

The expansion of pollinator-dependent crops, especially in the developing world, together with reports of worldwide pollinator declines, raises concern of possible yield gaps. Farmers directly reliant on pollination services for food supply often live in regions where our knowledge of pollination services is poor. In a manipulative experiment replicated at 23 sites across an Ethiopian agricultural

Incubators are organisations or structures that usually offer five types of services in order to accelerate start-up development: access to physical resources, administrative services, access to financial resources, assistance with start-up procedures and access to networks. The aim of the present paper is to investigate the mediating role of the incubator. More specifically, it examines how the i

This study examines cross-linguistic influence (CLI) in the acquisition of embedded wh-questions in L3 English in German-dominant heritage speakers (HSs) of Italian. Specifically, we investigate whether a higher proficiency in the heritage language Italian increases the potential for CLI from that language. To this end, 21 adult-aged Italian-German early bilinguals and 32 monolingual controls (L1

BACKGROUND: Epidemiological studies have linked transportation noise and cardiovascular diseases, however, atrial fibrillation (AF) has received limited attention. We aimed to investigate the association between transportation noise and AF risk.METHODS: Over the period 1990-2017 we estimated road and railway noise (Lden) at the most and least exposed façades for all residential addresses across De

Over the past half-century, drastically increased chemical fertilizers have entered agricultural ecosystems to promote crop production on the Yangtze Plain, potentially enhancing agricultural nutrient sources for eutrophication in freshwater ecosystems. However, long-term trends of nitrogen dynamics in terrestrial ecosystems and their impacts on eutrophication changes in this region remain poorly

Aims: Survival after cancer diagnosed during childhood or adolescence continues to improve with new treatments and supportive therapies. Optimal long-term care requires that risks to vulnerable organs are clearly defined and translated into guidelines that are implemented into practice. PanCareLIFE is a pan-European consortium that addresses survivorship issues comprising fertility, hearing impair

Crowdfunding is an innovative financial measure that is increasingly important in supporting sustainability initiatives. However, little research-based theory has been devoted to crowdfunding in light of the Sustainable Development Goals (SDGs). To bridge this gap, this study utilizes theories of value-attitude-behavior (VAB) model and personality to investigate Korean consumer crowdfunding behavi

Many students who enter college are insufficiently prepared to follow a demanding college-level curriculum. Thus, higher education institutions often require low-performing students to repeat failed courses, a full term, or even a full year. This paper is the first to investigate the effects of such a “(grade) retention” policy on student performance in higher education. We study a setting where f
