Statistiske metoder som regresjonsanalyse og kausale design basert på naturlige eksperi-menter har etter hvert blitt hyllevare innen de fleste fag som behandler store datamengder,ikke minst innen epidemiologi, meteorologi og klimavitenskap.1 Et eksempel er prinsipalkomponentanalyse (PCA), som brukes til å finne karakteristiske mønstre i geofysiske felt.Mønstrene, eller prinsipalkomponentene, ...

Spinochromes are part of a subgroups of quinones called naphthoquinones. These molecules have a series of bioactivity making them a promising target for marine researchers all over the world. Sulphated spinochromes was recently identified, but their structure or bioactivity is yet to be elucidated. In this project, an attempt to extract these sulphated spinochromes from red spherule cells are made. ...

<p>How might Ethiopia maintain its federal structure and its territory? ‘Constitutional contestation’ in Ethiopia is fuelled by two factors: regions and political parties follow ethnic line; and the Ethiopian Constitution has a secession clause. <p>A central challenge is to secure sufficient political trust. The public must be assured that authorities and individuals across regional borders generally ...

Objective - This study aims to investigate hormonal contraceptive (HC) use and user characteristics in women aged 40–49 years in Norway, as little is known on use of HCs in this age segment.<p> <p>Material and methods - This prevalence study included 2296 women aged 40–49 years who participated in the 2015–16 Tromsø Study, which collected self-reported sociodemographic information and data from ...

Objectives: To examine the precision of imaging measures commonly used to assess mandibular morphology in children and adolescents with juvenile idiopathic arthritis (JIA). Secondly, to compare cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) in the measurement of condylar height.<p> <p>Methods: Those included were children diagnosed with JIA during 2015–18 who had had ...

<p><b> Purpose</b> The purpose of this study is to examine role stress over the course of an alliance between supply chains. This study examines ambiguity as antecedent to multiple organisational outcomes. <p><b> Design/methodology/approach</b> This study subsequently uses a time series design that uses a close replication of the authors’ initial study. The design affords the opportunity ...

Recent experiments have confirmed earlier informal evidence that finite adjuncts are not islands categorically. Specifically, it has been shown that adjuncts are not necessarily islands for all dependency types (Sprouse et al. 2016), and that the island status of an adjunct depends on the type of the adjunct clause in question (Kush et al. 2019; Müller 2019; Bondevik et al. 2021; Nyvad et al. ...

In contrast to the conservative values of rural populations, cities are often seen as bulwarks of more tolerant, liberal and progressive values. This urban–rural divide in values has become one of the major fault lines in Western democracies, underpinning major political events of the last decade, not least the election of Donald Trump. Yet, beyond a small number of countries, there is little ...

A potential relationship between dysregulation of immune/inflammatory pathways and cognitive impairment has been suggested in severe mental illnesses (SMI), such as schizophrenia (SZ) and bipolar (BD) spectrum disorders. However, multivariate relationships between peripheral inflammatory/immune-related markers and cognitive domains are unclear, and many studies do not account for inter-individual ...

This paper focuses on the spectral properties of a bounded self-adjoint operator in <b><i>L</i>₂</i></b>(R^d) being the sum of a convolution operator with an integrable convolution kernel and an operator of multiplication by a continuous potential converging to zero at infinity. We study both the essential and the discrete spectra of this operator. It is shown that the essential ...
