Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The experiments illustrate the principle of equivalence

Since its inception in 1980, the International Christian Embassy Jerusalem (ICEJ) has developed into a central player in the formation of Christian Zionism globally. It is known through its high profile in Israeli society, its financial, moral and political support for the State of Israel and its controversial mix of theology and politics. This article focuses on ICEJ's ideological and theological

Gear manufacturing always results in some degree of manufacturing errors, i.e. deviations from the desired gear geometry. These errors alter how the gears mesh, typically causing increased contact pressure which in turn shortens service life. It is therefore crucial to choose tolerances such that excessive contact pressure, and especially tip contact, is avoided. With increasing demands due to ele

Regular goose counts made throughout Sweden since 1977/78 show that the total numbers staging and wintering in the country have increased markedly over the decades. October totals were of 51,000 geese in 1977, rising to c. 600,000 in 2018, during which time January totals also increased from 31,000 to 252,000 birds. The greatest change recorded was for the Greylag Goose Anser anser, numbers of whi

Structured reflective writing during clinical placement has been shown to be valuable for students’ learning and for their personal and professional development. The aim of this study was to examine clinical supervisors’ experiences of midwifery students’ daily written reflections on their practice at birthing units. A qualitative study was performed, and data were analysed using content analysis.

Previous studies on sustainability support the idea that the introduction of specific projects and certifications on sustainability increase the quality of wine production while specific requirements enhance environmental biodiversity and efficiency considering several aspects, such as water consumption and fertilizer use. These studies are mainly based on case studies and focus in particular on t

Objective: It is not known how much surfactant must be nebulized to reach a lung dose of phospholipids equivalent to that obtained by the instillation of 200 mg/kg of surfactant. We aimed to assess the feasibility of nebulizing a high-dose of poractant alfa with the eFlow-Neos investigational vibrating-membrane nebulizer in newborn piglets on nasal continuous positive airway pressure (nCPAP) and t

The Syrian conflict is far from over and the return of Syrian refugees is not indicative of mass influx into the country. Syrian refugees and their return have been instrumentalised and used as a politicai card and refugees should not be forced to return, as this would lead to further displacement and turmoil. Effective and consistent policies based on human rights, justice and accountability must

The thawing and subsequent decomposition of large stocks of soil organic carbon (SOC) currently stored in the northern circumpolar permafrost region are projected to result in a ‘positive’ feedback on global warming. The magnitude of this feedback can only be assessed with improved knowledge about the total size and geographic distribution of the permafrost SOC pool. This study investigates SOC st

The evolution of host range drives diversification in phytophagous insects, and understanding the female oviposition choices is pivotal for understanding host specialization. One controversial mechanism for female host choice is Hopkins’ host selection principle, where females are predicted to increase their preference for the host species they were feeding upon as larvae. A recent hypothesis posi

Thirty years ago, the Swedish tax system underwent a major reform. Since then there have been many changes to the tax system, and the general level of tax revenues has declined by over five percentage points of GDP. The decline in total revenues does not necessarily translate into an evenly distributed decline for taxpayers. This paper studies how tax payments have changed in Sweden since the majo

It is well known that capital constraints can hinder individuals to set up a business. Many business owners rely on own capital or capital from friends, fools and family in order to acquire required capital. In this paper, we study the role property plays for starting a business or becoming self-employed. Specifically, we investigate how property values and changes in property taxes affect the lik

Since the emergence of the recent coronavirus disease 2019 (COVID-19) and its spread as a pandemic, media was teeming with misinformation that led to psychologic, social and economic consequences among the global public. Probing knowledge and anxiety regarding this novel infectious disease is necessary to identify gaps in knowledge and sources of misinformation which can help public health efforts

Better understanding and reducing gender gaps in the labor market remains an important policy goal. We study the role of advice in sustaining these gender gaps using a laboratory experiment. In the experiment, “advisers” advise “workers” to choose between a more ambitious and a less ambitious task based on the worker’s subjective self-assessment. We expected female workers to be less confident and

Energy efficiency (EE) program administrators and policy makers have long encouraged the adoption of efficient technologies and conservation practices across all energy users and sectors. Energy users who haven’t yet participated in efficiency and conservation programs despite ongoing outreach are often referred to as “Hard-to-Reach” (HTR). These individuals or organizations can include, for insta

Background: Being overweight is becoming the new normal, and more than half of the adult Swedish population is overweight which poses a risk to public health. Overweight and obese women have both an increased risk and a worse prognosis for breast cancer, compared with women of normal weight. The breast cancer incidence in Sweden is increasing, and about one in nine women will be diagnosed with bre

Earth observation-based estimates of global gross primary production (GPP) are essential for understanding the response of the terrestrial biosphere to climatic change and other anthropogenic forcing. In this study, we attempt an ecosystem-level physiological approach of estimating GPP using an asymptotic light response function (LRF) between GPP and incoming photosynthetically active radiation (P

The current study was aimed at highlighting the role of blood pancreatic amylase in the regulation of glucose homeostasis and insulin secretion in a porcine model of streptozotocin- (STZ-) induced diabetes and in a rat pancreatic beta-cell line, BRIN-BD11. Blood glucose, plasma insulin, and glucagon levels were measured following a duodenal glucose tolerance test (IDGTT), in four pigs with STZ-ind
