Scoping review of positive mental health research for students in vocational education and training

Context: In this scoping review, we examine the knowledge base concerning positive mental health studies for students in vocational education and training (VET). The VET student population embraces approximately 30-52% of secondary school students in the Nordic countries, and 40% of the global student population. The risk of early school leaving (ESL) is substantially higher in VET than in general education and mental health may be a relevant factor in this matter. Yet, an overview of mental health studies in VET is lacking and therefore, this article aims to map empirical research studies that have explored positive mental health in VET students. The positive mental health framework, with its origin in Antonovsky\u27s (2002) salutogenesis and positive psychology, focuses on factors that promote mental health and wellbeing rather than taking on a pathological perspective. Methods: For our scoping review, we searched four databases, and 19 articles were found eligible for inclusion. These articles were systematically screened by means of a coding scheme to identify the following information: Country of origin of the study, its aim, research design, measures, conceptualization of mental health, and main findings. Results: The evidence suggests that positive mental health is understood as a multifaceted concept, and wellbeing is the dimension that is explored most often, followed by resilience and quality of life. The majority of the included studies used a validated questionnaire to assess various aspects of positive mental health, and most of them sought to explore correlations between different dimensions of positive mental health. Main findings of the studies suggest that a supportive school environment, physical activity, and a strong vocational identity may contribute to positive mental health for students in VET. Furthermore, correlations have also been identified between environmental factors and positive mental health. Finally, findings from the review illustrate how even small-scale interventions may have far-reaching effects, due to the interrelatedness of the different dimensions within the positive mental health construct. Conclusion: Findings from this review illustrate that numerous factors may affect the wellbeing of students in VET. In particular, a strong vocational identity, a supportive school environment, and physical activity may contribute to positive mental health. These findings suggest that VET teachers may promote the wellbeing of their students by providing a supportive psychosocial learning environment at school. (DIPF/Orig.

Sunlight effects on the 3D polar current system determined from low Earth orbit measurements

Interaction between the solar wind and the Earth's magnetosphere is associated with large-scale currents in the ionosphere at polar latitudes that flow along magnetic field lines (Birkeland currents) and horizontally. These current systems are tightly linked, but their global behaviors are rarely analyzed together. In this paper, we present estimates of the average global Birkeland currents and horizontal ionospheric currents from the same set of magnetic field measurements. The magnetic field measurements, from the low Earth orbiting $\textit{Swarm}$ and CHAMP satellites, are used to co-estimate poloidal and toroidal parts of the magnetic disturbance field, represented in magnetic apex coordinates. The use of apex coordinates reduces effects of longitudinal and hemispheric variations in the Earth's main field. We present global currents from both hemispheres during different sunlight conditions. The results show that the Birkeland currents vary with the conductivity, which depends most strongly on solar EUV emissions on the dayside and on particle precipitation at pre-midnight magnetic local times. In sunlight, the horizontal equivalent current flows in two cells, resembling an opposite ionospheric convection pattern, which implies that it is dominated by Hall currents. By combining the Birkeland current maps and the equivalent current, we are able to calculate the total horizontal current, without any assumptions about the conductivity. We show that the total horizontal current is close to zero in the polar cap when it is dark. That implies that the equivalent current, which is sensed by ground magnetometers, is largely canceled by the horizontal closure of the Birkeland currents

Magnetic Effects of Plasma Pressure Gradients in the Upper F Region

The Swarm satellites fly at altitudes that at polar latitudes are generally assumed to only contain currents that are aligned with the local magnetic field. Therefore, disturbances along the main field direction are mainly signatures of auroral electrojet currents, with a relatively smooth structure due to the distance from the currents. Here we show that superimposed on this smooth signal is an irregular pattern of small perturbations, which are anticorrelated with the plasma density measured by the Langmuir probe. We show that the perturbations can be remarkably well reproduced by assuming they represent a j  × B force, which balances the plasma pressure gradient implied by the density variations. The associated diamagnetic current, previously reported to be most important near the equator, appears to be a ubiquitous phenomenon also at polar latitudes. A spectral analysis indicates that this effect dominates magnetic field intensity variations at small‐scale sizes of a few tens of kilometers.publishedVersio

Motivasjoner og reservasjoner: En studie av bruken og spredningen av klimakalkulatoren blant bønder i Nordland

In 2019 the agricultural organizations in Norway signed a letter of intent with the Norwegian government, with the goal of cutting 5 million tons of CO2-equvalents from the agricultural sector by 2030, both through direct emission cuts and through soil carbon sequestration. In 2020 the Norwegian Agrarian Association launched “the agricultural sector´s climate plan”, a plan that through a focus on eight specific measures was aimed at reaching the desired amount of emission cuts. The first of these measures was the “climate calculator”, a tool that would give individual farmers the ability to reduce their farm´s emissions based, among other things, on their unique geographical context. At the time of writing, there are eight growing seasons left until the goal in the letter of intent from 2019 is supposed to have been reached. This study uses theories of diffusion and of sustainable intensification to research how the climate calculator spreads and in what way it can contribute to emission cuts. In the study I have interviewed ten farmers in Nordland about their motivations for and reservations against using the climate calculator to reduce the emissions from their productions. I have then used their responses to research what may stand in the way of a more widespread implementation of this tool. In addition, I have interviewed a key informant on the climate calculator in order to understand more about how this tool arose, and the processes that lead to its initial launch. My study shows that the name of the “climate calculator” carries negative connotations for almost all my interviewees. The study also shows that another critique of the tool that unites my interviewees is the fear that the climate calculator will be time-consuming to learn and to use. In addition to this, my results show that the farmers I have interviewed often don’t know about the economic support and compensation they can apply for if they use the calculator. Another of my findings is that the beforementioned letter of intent is weakly anchored among the farmers in my sample and that they therefore know little about why the climate calculator exists. All of this in combination is strengthening the already existing feeling among the farmers that the calculator is “yet another mandatory measure implemented against their will”. My study also shows that there are several factors delaying a more widespread implementation of the tool. One of these is the fact that the diffusion and use of the climate calculator in Nordland seems to be influenced strongly by whether or not there are dedicated climate- and agricultural advisors in the area.Masteroppgave i geografiGEO350MASV-GEOGMASV-PHYGMASV-MEHAMPGEOG

Climatology of the Auroral Electrojets Derived From the Along-Track Gradient of Magnetic Field Intensity Measured by POGO, Magsat, CHAMP, and Swarm

The auroral electrojets (AEJs) are complex and dynamic horizontal ionospheric electric currents which form ovals around Earth’s poles, being controlled by the morphology of the main magnetic field and the energy input from the solar wind interaction with the magnetosphere. The strength and location of the AEJ varies with solar wind conditions and the solar cycle but should also be controlled on decadal timescales by main field secular variation. To determine the AEJ climatology, we use data from four polar Low Earth Orbit magnetic satellite missions: POGO, Magsat, CHAMP, and Swarm. A simple estimation of the AEJ strength and latitude is made from each pass of the satellites, from peaks in the along-track gradient of the magnetic field intensity after subtracting a core and crustal magnetic field model. This measure of the AEJ activity is used to study the response in different sectors of magnetic local time (MLT) during different seasons and directions of the interplanetary magnetic field (IMF). We find a season-dependent hemispherical asymmetry in the AEJ response to IMF By, with a tendency toward stronger (weaker) AEJ currents in the north than the south during By>0 (By<0) around local winter. This effect disappears during local summer when we find a tendency toward stronger currents in the south than the north. The solar cycle modulation of the AEJ and the long-term shifting of its position and strength due to the core field variation are presented as challenges to internal field modelling

Evolution of IMF By induced asymmetries during substorms: Superposed epoch analysis at geosynchronous orbit

The By component of the magnetic field inside the magnetosphere is positively correlated with the By component of the Interplanetary Magnetic Field (IMF). This leads to asymmetries in aurora, plasma convection and electric currents between the northern and southern hemispheres It has been demonstrated that magnetic conjugate locations in the northern and southern ionosphere become less displaced during magnetospheric substorms, which are associated with enhanced reconnection in the near-Earth tail. Here we directly address how the average By component in the magnetotail evolves relative to substorm onset by performing a superposed epoch analysis of the magnetic field observed at nightside geosynchronous orbit during periods with dominant IMF By. The observations demonstrate that the average |By| in the magnetotail increases during the loading phase prior to onset. |By| maximizes in the expansion phase and is subsequently reduced during the remaining unloading phase. The observed trends become more pronounced using substorm onset lists that on average identify stronger substorms. Since dayside reconnection dominates over tail reconnection during the loading phase, whereas tail reconnection dominates during the unloading phase, the results demonstrate how asymmetries build up during periods with low tail reconnection and are reduced during periods with enhanced tail reconnection in agreement with previous case studies of conjugate auroral substorm features.publishedVersio

Polar ionospheric currents and high temporal resolution geomagnetic field models

Estimating high resolution models of the Earth's core magnetic field and its time variation in the polar regions requires that one can adequately account for magnetic signals produced by polar ionospheric currents, which vary on a wide range of time and length scales. Limitations of existing ionospheric field models in the challenging polar regions can adversely affect core field models, which in turn has important implications for studies of the core flow dynamics in those regions. Here we implement a new approach to co-estimate a climatological model of the ionospheric field together with a model of the internal and magnetospheric fields within the CHAOS geomagnetic field modelling framework. The parametrization of the ionospheric field exploits non-orthogonal magnetic coordinates and scales linearly with external driving parameters related to the solar wind and the interplanetary magnetic field. Using this approach we derive a new geomagnetic field model from measurements of the magnetic field collected by low Earth orbit satellites, which in addition to the internal field provides estimates of the typical current system in the polar ionosphere. We find that the time derivative of the estimated internal field is less contaminated by the polar currents, which is mostly visible in the zonal and near-zonal terms at high spherical harmonic degrees. Distinctive patches of strong secular variation at the core-mantle boundary, which have important implications for core dynamics, persist. Relaxing the temporal regularisation reveals annual oscillations, which could indicate remaining ionospheric field or related induced signals in the internal field model. Using principal component analysis we find that the annual oscillations mostly affect the zonal low-degree spherical harmonics of the internal field.Comment: 26 pages, 15 figures, 3 table
