More than a token photo: humanizing scientists enhances student engagement.

Despite broad consensus that highlighting counter-stereotypical scientist role models in educational materials promotes equity and success, the specific elements that make these materials effective remain untested. Are pictures of counter-stereotypical scientists enough to communicate to students that scientists come from a variety of backgrounds, or is additional information required? To parse the effects of including visual depictions and humanizing information about scientists featured in biology course materials, we distributed three randomized versions of assignments over several academic terms across 36 undergraduate institutions ( > 3700 students). We found that including humanizing information about scientists was key to increasing student engagement with the biology course materials.

"Scientists are People too": Biology Students Relate More to Scientists When They are Humanized in Course Materials.

Featuring scientists in classroom materials provides opportunities for students to relate to scientists as role models and see themselves in science. However, it is unclear what information students find most relatable when encountering scientists throughout their education. In this study, we manipulated the amount and type of information provided about scientists featured in biology courses.

Exploring the lived experience: impact of dementia diagnosis on individuals with cognitive impairment - a qualitative study.

Objective: Although knowledge about the experience of being diagnosed with dementia is limited, with the expected rise in dementia's prevalence in the coming decades, such knowledge is pivotal for the people diagnosed, their families, and healthcare planners. Thus, the aim of our study was to explore the experience of living with cognitive impairment and dementia and the impact of being diagnosed with dementia.

Method: A qualitative design was applied.

Knowledge and motivation to adopt recommended health behaviours to reduce dementia risk among the elderly in Norway: a qualitative study.

Objectives: Dementia is a major healthcare challenge; however, there is evidence that modifiable risk factors may contribute to reduce dementia risk. The aim of the study was to explore the knowledge and motivation for adopting recommended health behaviours among older adults in Norway.

Study Design: The study has a qualitative, descriptive design.

Public knowledge about dementia risk reduction in Norway.

Background: Several modifiable lifestyle risk factors for dementia have been identified, but it is unclear how much the Norwegian public knows about the relationship between lifestyle and brain health. Therefore, this study aimed to investigate knowledge about modifiable dementia risk and protective factors and beliefs and attitudes towards dementia and dementia risk reduction in a randomly selected subsample of the Norwegian population.

Methods: The total sample (n = 1435) included individuals aged 40-70 years from four counties (Oslo, Innlandet, Nordland and Trøndelag) in Norway.

Successful eradication of Mycoplasma hyopneumoniae from the Norwegian pig population - 10 years later.

Background: Mycoplasma hyopneumoniae (Mhyo) is the causative agent of enzootic pneumonia in pigs which adversely affects animal health and welfare, in addition to causing considerable economical losses. This paper presents the implementation of the national Mhyo eradication program in Norway, the subsequent population wide surveillance and documentation on the current freedom from Mhyo in the Norwegian pig population. In 1994, the Board of The Norwegian Pig Health Service decided on conducting a national surveillance and eradication program for Mhyo.

The Human Brain Representation of Odor Identification in Amnestic Mild Cognitive Impairment and Alzheimer's Dementia of Mild Degree.

Odor identification (OI) ability is a suggested early biomarker of Alzheimer's disease. In this study, we investigated brain activity within the brain's olfactory network associated with OI in patients with amnestic mild cognitive impairment (aMCI) and mild Alzheimer's dementia (mAD) to uncover the neuronal basis of this impairment. Patients with aMCI ( = 11) or mAD ( = 6) and 28 healthy older adults underwent OI functional MRI (fMRI) at 3T, OI, odor discrimination, and cognitive tests and apolipoprotein-e4 (APOE4) genotyping.

Getting Messy with Authentic Data: Exploring the Potential of Using Data from Scientific Research to Support Student Data Literacy.

Data are becoming increasingly important in science and society, and thus data literacy is a vital asset to students as they prepare for careers in and outside science, technology, engineering, and mathematics and go on to lead productive lives. In this paper, we discuss why the strongest learning experiences surrounding data literacy may arise when students are given opportunities to work with authentic data from scientific research. First, we explore the overlap between the fields of quantitative reasoning, data science, and data literacy, specifically focusing on how data literacy results from practicing quantitative reasoning and data science in the context of authentic data.

Global Study of Social Odor Awareness.

Olfaction plays an important role in human social communication, including multiple domains in which people often rely on their sense of smell in the social context. The importance of the sense of smell and its role can however vary inter-individually and culturally. Despite the growing body of literature on differences in olfactory performance or hedonic preferences across the globe, the aspects of a given culture as well as culturally universal individual differences affecting odor awareness in human social life remain unknown.

The brain structural and cognitive basis of odor identification deficits in mild cognitive impairment and Alzheimer's disease.

Background: The objectives of this study were to explore the relationship between olfactory impairment, cognitive measures, and brain structure volumes in healthy elderly individuals, compared to patients with amnestic mild cognitive impairment (aMCI) or early Alzheimer's disease (AD). The primary aim was to elucidate possible differences in cognitive scores and brain structure volumes between aMCI/AD patients with relatively intact odor identification (OI) ability and those with reduced ability.

Methods: Twelve patients with aMCI, six with early AD, and 30 control subjects were included.

Hippocampal involvement in retrieval of odor vs. object memories.

The aim of this study was to investigate the role of the human hippocampus in episodic retrieval of odors, in comparison with episodic retrieval of visual objects. Subjects encoded a set of unique odors and objects, and retrieval was tested the next day during functional magnetic resonance imaging (fMRI). Subjects were shown the names of old (studied) and new (unstudied) odors and objects, and asked to indicate which of these stimuli had been presented the previous day.

The human brain representation of odor identification.

Odor identification (OI) tests are increasingly used clinically as biomarkers for Alzheimer's disease and schizophrenia. The aim of this study was to directly compare the neuronal correlates to identified odors vs. nonidentified odors.

Use of the Brief Smell Identification Test for olfactory deficit in a Norwegian population with Alzheimer's disease.

Aims: Several studies have shown that Alzheimer's disease (AD) is associated with hyposmia. Olfactory identification may be a cheap and simple additional test in the assessment of early cognitive changes. The sense of smell is influenced by factors such as experience and culture and the aim of the present study was to assess the validity of the Brief Smell Identification Test (B-SIT) in distinguishing patients with AD from healthy gender and age-matched controls in a Norwegian population.

Better primary physician services lead to fewer hospital admissions.

The aim of the study was to examine whether improved quality of primary physician services, measured by patient satisfaction, leads to fewer admissions to somatic hospitals. We studied differences in hospital admissions at the municipality level in Norway. In addition to the standard explanatory variables for use of hospitals--gender, age, socio-economic status and travelling distance to the nearest hospital--we also included a measure of patient satisfaction with primary physician services in the municipality.
