Analyzing buyer behavior when selecting green criteria in public procurement
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
Given the complexity of green public procurement, decisions are likely to be driven by bounded rationality. However, we know little about what determines supplier selection criteria in any given situation. This study explores buyer behavior when considering environmental criteria. We first conducted interviews and identified 12 operational procedures used by buyers. We then developed a survey to ...
Protocol for the Northern babies longitudinal study: predicting postpartum depression and improving parent–infant interaction with The Newborn Behavioral Observation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-27)
Postpartum depression (PPD) is a prevalent
disorder. Studying the factors related to PPD will help
to identify families at risk and provide preventive
interventions. This can in turn improve the developmental
trajectories for the children. Several previous studies
have investigated risk factors for PPD. However, few
studies have focused on cognitive vulnerability factors.
The first aim of the ...
Global cortical thinning in acute anorexia nervosa normalizes following long-term weight restoration
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-09-22)
<b>Background:</b> Anorexia nervosa (AN) is a serious eating disorder characterized by selfstarvation,
extreme weight loss and alterations in brain structure. Structural magnetic
resonance imaging (sMRI) studies have documented brain volume reductions in acute AN,
but it is unclear whether they are 1) regionally-specific or 2) reversible following weight
restoration. Here, we measured cortical ...
On the measurement of procrastination: Comparing two scales in six European countries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-31)
Procrastination is a common problem, but defining and measuring it has been subject to
some debate. This paper summarizes results from students and employees (N = 2893)
in Finland, Germany, Italy, Norway, Poland, and Sweden using the Pure Procrastination
Scale (PPS) and the Irrational Procrastination Scale (IPS; Steel, 2010), both assumed
to measure unidimensional and closely related constructs. ...
A two-stage cognitive theory of the positive symptoms of psychosis. Highlighting the role of lowered decision thresholds
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
<b>Objectives:</b> We outline a two-stage heuristic account for the pathogenesis of the positive symptoms of
psychosis.
<b>Methods:</b> A narrative review on the empirical evidence of the liberal acceptance (LA) account of positive
symptoms is presented.
<b>Hypothesis:</b> At the heart of our theory is the idea that psychosis is characterized by a lowered decision
threshold, which results in ...
A Bayesian perspective on delusions: Suggestions for modifying two reasoning tasks
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08)
Background and objectives:<br>There are a range of mechanistic explanations on the formation and maintenance
of delusions. Within the Bayesian brain hypothesis, particularly within the framework of predictive
coding models, delusions are seen as an aberrant inference process characterized by either a
failure in sensory attenuation or an aberrant weighting of prior experience. Testing of these ...
Simple ears - flexible behavior: Information processing in the moth auditory pathway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03)
Abstract Lepidoptera evolved tympanic ears in response to echolocating bats. Comparative studies have shown that moth ears
evolved many times independently from chordotonal organs. With only 1 to 4 receptor cells, they are one of the simplest hearing
organs. The small number of receptors does not imply simplicity, neither in behavior nor in the neural circuit. Behaviorally, the
response to ...
Playing a video game is more than mere procrastination
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-13)
<i>Background</i>: Procrastination is seen as a severe problem among young people, and many factors have been claimed to
be associated with it, playing video games being one of them. One of the reasons why video games might be related to
procrastination is their ability to offer instant gratification and feedback, while at the same time offer distractions from less
tempting and rewarding tasks. ...
The Psychological Science Accelerator: Advancing Psychology Through a Distributed Collaborative Network
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-01)
Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across ...
Communicating public avalanche warnings – what works?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-20)
Like many other mountainous countries, Norway has experienced a rapid increase in both recreational winter activities and fatalities in avalanche terrain during the past few decades: during the decade 2008–2017, 64 recreational avalanche fatalities were recorded in Norway. This is a 106% increase from that of the previous decade. In 2013, Norway therefore launched the National Avalanche Warning ...
