Vi människor ingår i ett flertal olika grupper i vårt vardagliga liv då exempelvis våra arbetskamrater utgör en grupp och våra familjer utgör en annan. Med hjälp av Internet och teknikens framsteg har nya mötesplatser framkommit i form av virtuella världar där nya typer av grupper skapas. Här möts gruppmedlemmarna inte ansikte mot ansikte utan har i många fall endast textbaserad kommunikation som
To investigate the symbiotic interaction of Trichoderma harzianum Rifai on Chenopodium quinoa Willd. in isolation, we studied axenic co-culture of the T. harzianum isolates T-22 and BOL-12QD and the C. quinoa cultivars Kurmi and Maniqueña real. Neither T-22 nor BOL-12QD affected seedling growth during two days of co-culture in the early growth phase of rapid primary root extension.

Problem-based learning (PBL) has proven to be highly effective for educating students in an active and self-motivated manner in various disciplines. Student projects carried out following PBL principles are very dynamic and carry a high level of uncertainty, both conditions under which agile project management approaches are assumed to be highly supportive. The paper describes an empirical case st
The purpose of the paper is to explore knowledge accumulation in research on pedagogy in entrepreneurship education, with particular attention to how core journal outlets, core topics and core scholarly works have developed over time. The authors combine a systematic literature review technique and bibliometric analysis to depict the development of this stream of research in the period 1995–2018.

I detta delprojekt har följande genomförts:• Beräkning av effekterna av solinstrålning och förvärmning av luften vid inglasning av befintliga byggnader• Beräkning av energibesparing vid inglasning• Beräkning av termisk komfort och studie av effektiva passiva kylåtgärder• Framtagande av datorverktyg (modeller och moduler för energiberäkningsprogram, Glazing-LTH) för att bättre kunna uppskatta effek
This paper evaluates the cost-effectiveness of renovating single-family houses to Passive House level, as compared to maintaining the existing buildings or renovating to building regulation level. The assessment involved life cycle cost analyses, and concerns the Swedish single-family housing stock constructed between 1961 and 1980, which accounts for about a third of Sweden’s two million single-f
This article chronicles the most recent history of the Deutsches Elektronen-Synchrotron (DESY) located in Hamburg, Germany, with particular emphasis on how this national laboratory founded for accelerator-based particle physics shifted its research program toward multi-disciplinary photon science. Synchrotron radiation became DESY’s central experimental research program through a series of changes
SUMMARYHigh prenatal detection rates of complex congenital heart defects (CHD) Aim: To analyze prenatal detection rates of complex CHD after the implementation of an expanded three-tiered screening model at the Skane University Hospitals in Lund and Malmö in 2015. Methods: Retrospective review of pregnancies screened from January 1, 2015 and being born by June 30, 2018. Complex CHD was defined as
We study in detail the linear flow of particles on a graph with one vertex and k+1 infinite edges. This has a rich environment with many different emergent behaviours depending on the system parameters. The abrupt change in the behaviour of the system along a continuous change of the parameters manifests multiple phase transitions.We discuss the physical interpretation of the considered simple modWe study in detail the linear flow of particles on a graph with onevertex and k+1 infinite edges.

It is increasingly evident that the centre of gravity of international relations is shifting in the direction of Asia. China’s economic and political rise is the single most important dimension of this development. This coincides with fading American hegemony, obvious during, but in essence not limited to, the Trump Presidency. These actor-level changes take place within a context of structural chIt is increasingly evident that the centre of gravity of international relations is shifting in the direction of Asia.

Recently we have called for the broadening of the theoretical base in order to understand the social and other contexts of material culture items such as pottery (Pikirayi and Llndahl, 2013). The challenges encountered by archaeologists remain the huge ceramic assemblages, which are however, central in defining group identities in southern African Iron Age studies. but whose analyses Is always rel
Workplace incivility is a pervasive issue with implications for employee well-being. Drawing upon Self-Determination Theory, this study explores the association between experienced workplace incivility, need satisfaction, and work motivation and investigates whether workplace incivility is negatively associated with autonomous work motivation. We hypothesize that experiencing workplace incivility
Artikeln påminner svensk praktisk teologi om dess historiskt givna identitet samt visar att denna identitet härleds ur ett bestämt encyklopediskt sammanhang. Utgångspunkten för den encyklopediska bestämningen är att akademisk teologi är en i Schleiermachers mening positiv vetenskap, vars uppgift är att främja kyrka och kristendom. I denna positiva vetenskap har den praktiska teologin rollen av proThe purpose of this article is to remind Practical Theology in Sweden of its historically given identity and to show that this identity derives from a welldefined encyclopedic context. The point of departure is that theology is a positive science, in the sense used by Friedrich Schleiermacher: a science directed towards a specific goal, which in theology's case is the wellinformed government of th
Vildsvin är ett omdiskuterat djurslag i Sverige. Många ser dem som ett uppskattat inslag i naturen, dels som jaktbyte och dels för att de bidrar till naturupplevelser, skogstillväxt och biologisk mångfald. Samtidigt orsakar de skador på jord- och skogsbruk, villatomter och grönområden samt trafikolyckor. Dessa kostnader drabbar ofta andra än dem som anser sig dra nytta av vildsvinens existens. Und

Train delays are often monitored using lag indicators of achieved punctuality levels, but indicators can also be used proactively as lead indicators to help reach a certain level of punctuality. In this paper, two lead indicators – the share of delayed dwell times and the share of delayed run times – are formulated and tested on Swedish commuter train data for the years 2001-2020. Results show tha
Introduction: The purpose of this study was to experimentally investigate the effects of changes in both quantity and quality of use of social networking sites (SNS) on measures of anxiety, depression, stress, self-esteem, loneliness, problematic social media use, and present focused awareness. Method: Participants were randomly assigned to three different conditions: reducing SNS time to 30 minut
Women’s football is in comparison to men’s football experiencing a fall behind. The gap between men’s and women’s football is visible reviewing and comparing viewers statistics, revenue generated, media attention and players salary. Governing bodies of association football, football clubs and corporate actors have in previous years started to actively invest in women’s football to equalize the gap
