Effect of Sex, Body Mass Index and Physical Activity Level on Peak Oxygen Uptake Among 14–19 Years Old Adolescents
2020
The aim was to describe longitudinal trends in peak oxygen uptake (VO2peak) among 14- to 19-year-old adolescents in Norway, and to examine effects of sex, body mass index (BMI), and physical activity (PA) level on VO2peak during adolescence. Of 124 invited students from two lower secondary schools in Norway, 116 eighth-grade students (61 boys and 55 girls; 14 years old at baseline) volunteered to participate. The study has a longitudinal design with 6 yearly repeated measures of body height and mass, VO2peak and PA level. VO2peak allometrically scaled to body mass raised to the power of 0.67 was measured using a walking or running incremental test on a treadmill, whereas PA level was self-r…
Comparison of 99mTc-Labeled Colloid SPECT/CT and Planar Lymphoscintigraphy in Sentinel Lymph Node Detection in Patients with Melanoma: A Meta-Analysis
2020
We compared the detection rate (DR) for sentinel lymph nodes (SLNS), the number of SLNs and the subjects with additional SLNs of single-photon emission computed tomography (SPECT/CT) and planar lymphoscintigraphy (PL) in patients with melanoma. Furthermore, we evaluated the impact of SPECT/CT on surgical plans. Articles containing head-to-head comparisons between SPECT/CT and PL were searched in Pubmed/MEDLINE and Scopus. The literature search was updated until December 31st, 2019. DR was calculated on a per-patient-based analysis; the studies were pooled by their odds ratios (ORs) with a random effects model to assess the significance of difference (p < 0.05). The number of additional S…
Enhanced chain dynamics in loop-sorting-systems by means of layout optimization and a kinematic model of the polygon action
2012
Published version of an article in the journal: Structural and Multidisciplinary Optimization. Also available from the publisher at: http://dx.doi.org/10.1007/s00158-011-0743-7 Poor dynamics owing to polygon action is a known concern in mechanical applications of closed articulated chains. In this paper a kinematic model of the polygon action in large chains of loop-sorting-systems is proposed. Through optimization techniques the chain dynamics is improved by minimizing the polygon action using a parametric model of the track layout as design variables. Three formulations of the kinematic polygon action are tested on an average sized planer tracks layout to find a superior model. Verificati…
Haptic Perception in Extreme Obesity: qEEG Study Focused on Predictive Coding and Body Schema
2020
Haptic perception (HP) is a perceptual modality requiring manual exploration to elaborate the physical characteristics of external stimuli through multisensory integrative cortical pathways. Cortical areas exploit processes of predictive coding that collect sensorial inputs to build and update internal perceptual models. Modifications to the internal representation of the body have been associated with eating disorders. In the light of this, obese subjects were selected as a valid experimental model to explore predictive coding in haptic perception. To this purpose, we performed electroencephalographic (EEG) continuous recordings during a haptic task in normally weighted versus obese subjec…
Skolotāja valoda angļu valodas stundās pozitīvu attiecību veidošanai klasē
2017
Pētījums aplūko kā skolotāju klases valoda palīdz veidot pozitīvas savstarpējās attiecības klasē, jo pozitīvai atmosfērai klasē ir nozīmīga loma svešvalodu apguvē. Aptaujā – pētījumā tika izmantotas šādas datu ieguves metodes: anketas piekto līdz divpadsmito klašu skolēniem, angļu valodas stundu novērošanas pieraksti, intervijas ar angļu valodas skolotājiem. Iegūtie dati atklāj skolēnu viedokli par angļu valodas skolotājiem un angļu valodas stundām, norādot, ka skolotājiem ir nepieciešams vairāk domāt par visu skolēnu iesaistīšanu mācību stundā, skolotāja lietotās valodas sarežģītību un runas ātrumu, kā arī vienādu attieksmi pret visiem skolēniem. Novērojot angļu valodas stundas, autore pie…
The Healthy Body Image intervention and reduction in eating disorder symptomatology and muscle building supplement use in high school students: a stu…
2022
BackgroundMediation analysis is important to test the theoretical framework underpinning an intervention. We therefore aimed to investigate if the healthy body image (HBI) intervention’s effect on eating disorder (ED) symptomatology and use of muscle building supplements was mediated by the change in risk and protective factors for ED development and muscle building supplement use.MethodsThis study used data from the HBI intervention: a cluster randomized controlled universal intervention aiming to promote positive body image and embodiment and reduce the risk for ED development including 30 schools in Norway. A total of 1,713 (37% boys) participants were included in the analyses. Condition…
Sensory Organ Investment Varies with Body Size and Sex in the Butterfly Pieris napi
2021
Simple Summary Pollinating insects rely on a range of senses such as vision, olfaction, gustation, and mechanosensation to utilise, locate, and fly between floral resources. The size of different sensory organs determines their sensitivity and provides an indication of their relative importance—larger organs can enhance sensitivity by increasing the number or size of sensing structures. However, increasing the relative size of an organ would require additional energy for developing and maintaining it. This likely leads to a trade-off between the energy invested into different sensory systems within individuals. To explore how the size of the sensory organs vary with body size in insect poll…
The phenomenology of proximity violence: relational strategies and modalities used against vulnerable migrants
2019
The chapter describes an umbrella concept, proximity violence, of which violence against women is only one manifestation. Of this phenomenon , the author endeavoured to highlight the patterns that make defining its material contours and specifying the tesserae that compose it difficult. In fact cultural factors, contingent situations became entangled with concrete elements of pain and abuse of the victims. It was, therefore, a matter of betting, on the possibility of representing a phenomenon by devising a bridge between theories of gender-based violence and the “thing” – the violence of those who are not strangers and in whom, for different reasons, we trust. Filling this vacuum employing …

Kobieca strona dyskursu onkologicznego. Empiryczne spojrzenie na demokratyzację wiedzy medycznej
2015
Artykuł poprzez osadzanie w teoretycznych ramach konstruktywizmu wpisuje chorobę nowotworową piersi w kategorię dyskursu. Takie podejście wymaga zadania pytań o depozytariuszy wiedzy medycznej oraz jej źródła, formy i sposoby dystrybucji. Nie chodzi tu o negację istnienia określonych jednostek chorobowych, lecz raczej zwrócenie uwagi na złożone powiązania pomiędzy wiedzą medyczną a światem społecznym. Klarowny obraz obiektywnej wiedzy zaczyna tracić jednoznaczne kontury, gdy zestawi się alternatywne reprezentacje językowe w odmienny sposób porządkujące i interpretujące doświadczenia związane ze zdrowiem i chorobą. Na płaszczyźnie empirycznej analiza opiera się na wynikach badań ilościowych,…
