Effects of a falls prevention exercise programme on health-related quality of life in older home care recipients: a randomised controlled trial
Does academia disfavor contextual and extraverted students
In a study conducted at Norwegian University of Life Sciences (NMBU) 288 students volunteered to answer an electronic questionnaire constructed to classify their personality type (16 categories), their work habits and preferences, operational values and preferred direction (leadership). In addition exam grades from nine undergraduate subjects, some mathematical and some non-mathematical, were obtained for the same students. Statistical analyses revealed a clear connection between grades and some personality characteristics. This should by no means interpreted as differences in skills, but rather as an indication of biased teaching style and pedagogical structure in the university. The results show across all the nine subjects that the traditional teaching structure in universities with lectures in large auditoriums with limited dialog, a rigid and structured curriculum, textbook reading and paper-and-pencil tests, clearly disfavors students which can be characterized as extraverted and contextual/relational, and to some extent also those being intuitive and feeling. Among these students we typically find those being altruistic, creative and out-of-the box thinking. It is suggestive that academia, to probably a large extent, fail to bring such resourceful people to positions were their talents really can make a difference, for instance in research
PROFIL MODEL MENTAL SISWA PADA MATERI KELARUTAN DAN HASIL KALI KELARUTAN DENGAN MENGGUNAKAN TDM-POE
Penelitian ini bertujuan untuk memperoleh profil model mental siswa pada materi materi kelarutan dan hasil kali kelarutan. Subyek penelitian yaitu siswa SMA kelas XI yang terdiri dari 30 siswa di beberapa SMA di kota Bandung yang sudah mempelajari materi kelarutan dan hasil kali kelarutan. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif dengan instrumen penelitian berupa tes diagnostik model mental predict-observe-explain (TDM-POE). Jawaban siswa pada tahap prediksi mencakup level submikroskopik, tahap observasi mencakup level makroskopik dan tahap eksplanasi yaitu mempertautkan ketiga level representasi (makroskopik, submikroskopik dan simbolik). Pada konsep terbentuknya endapan, sebagian siswa cenderung hanya memahami secara makroskopik tapi tidak dapat memahami secara submikroskopik. Pada konsep penambahan ion senama, 9 dari 30 siswa yang mampu menjelaskan berdasarkan prinsip pergeseran kesetimbangan dan secara perhitungan. Pada konsep pengaruh pH, 20 dari 30 siswa tidak mampu menjelaskan secara submikroskopik dan simbolik.

Associations between health-related quality of life, physical function and fear of falling in older fallers receiving home care
Falls and injuries in older adults have significant consequences and costs, both personal and to society. Although having a high incidence of falls, high prevalence of fear of falling and a lower quality of life, older adults receiving home care are underrepresented in research on older fallers. The objective of this study is to determine the associations between health-related quality of life (HRQOL), fear of falling and physical function in older fallers receiving home care
Sámi Feminism and Activism in Ann-Helén Laestadius’ Novel Stöld
This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.The article examines the thematization of (intersectional indigenous) feminist criticism and activism in the novel Stöld (2021), written by the Sámi-Tornedalian-Swedish author Ann-Helén Laestadius. The novel depicts life in a small town in Sápmi, where reindeer herders are strongly affected by the brutal killings of their animals and the lack of legal security they experience. A central motif in the novel is the resistance to this discrimination through the characters Elsa’s and Minna’s Sámi and feminist activism. The first part of the analysis examines their common Sámi causes and activist strategies; and the second focuses on the critique of gender norms within the minoritized reindeer herding society, and investigates the gendered attitudes towards their activism. Finally, I discuss the ways in which the novel functions as literary activism. In sum, the book shows that it requires the effort of several women acting across generations through various institutions such as the police, the media, and the judicial system to create changepublishedVersio
Implementing Hydropower Scheduling in a European Expansion Planning Model
This Master s thesis proposes a method for implementing an enhanced hydropower planning formulation in a long-term expansion planning model. The motivation for this work is the important role that hydropower plays in a generation investment environment. In a time where penetration of intermittent renewable energy sources like wind and solar power is heavily increasing, new challenges in the continuous balancing of supply and demand are also introduced. Hydropower and its use of reservoirs as power batteries can respond more or less immediately to such fluctuations. As such, a detailed framework for hydropower scheduling is highly relevant.The presented implementation is carried out in an already-existing expansion planning model for Europe called EMPIRE, which is written in Mosel Xpress. This is a two-stage stochastic optimization model whose objective function is to minimize the total net present value of expected operational costs and investment costs for generation and transmission capacities.The main feature of the proposed framework involves penalization of hydropower through water values. This necessitates a complete hydropower scheduling representation where each reservoir is divided into segments which are assigned a fictitious marginal cost. The inclusion of water values enables comparability with the short-run marginal cost for competitive technologies and introduces the important aspect of conserving water for other periods of the year. Data from SINTEF Energy Research has been used for this purpose.Results from optimization runs in the time span from 2010 to 2060 for an EU 20-20-20 like policy scenario show that the original hydropower availability is too relaxed, thereby causing an overvaluation of this technology. The revamped cost representation by means of water values leads to a lower utilization of hydropower relative to the original model. An earlier deployment of solar power is carried out to replace the lower generation, with a capacity difference between the final and original models peaking at 45% in 2040. Total costs in the system are therefore increased. For both models extensive investments in intermittent renewables are taking place, amounting to 47% of the total capacity in 2060
The Origin and Genetic Architecture of Anomalous Coat Color in the Severely Inbred Scandinavian Wolf Population
Understanding how genetic drift and inbreeding can shape phenotypic traits in small and isolated populations, by facilitating the expression of rare genetic variants, can be important for the conservation and management of such populations by reflecting their demographic history and constraints. After the grey wolf (Canis lupus) recolonized the Scandinavian peninsula (Norway and Sweden), the population has remained small and isolated. In consequence, the population is highly inbred and originates from seven individuals, only. With insufficient immigration due to isolation, the loss of genetic variation through genetic drift and inbreeding is severe. Various negative effects of inbreeding have already been documented, such as inbreeding depression and several congenital deformities. Additionally, there have been reports of Scandinavian wolves exhibiting anomalous coat color characterized by hypopigmentation displayed as white tail tips, and for some individuals, also larger white patches. In this study, I utilized long-term monitoring data of the population, dating back to its recolonization, to examine the occurrence of anomalous coat color by investigating its origin and inheritance, genetic mechanism, and effects of inbreeding on its expression.
SNP genotyping revealed a distinct haplotype linked to the MITF gene that co-segregated with anomalous coat color. The only genotyped individual homozygous for this haplotype was anomalously colored, whereas heterozygous carriers had either normal or an unknown phenotype, and the majority of wolves did not carry the haplotype at all. This demonstrates that anomalous coat color can be attributed to genetic variation involving the MITF gene and is likely linked to the disruption of melanocyte development, leading to unpigmented areas and the occurrence of hypopigmentation. The origin of this haplotype could be traced back to the third founder of the population, reproducing for the first time in 1991. All genotyped offspring of this founder were heterozygous carriers, whereas the haplotype was absent in the founding pair and their descendants. The haplotype showed a recessive mode of inheritance, where two copies were required for the expression of anomalous coat color. With evidence of recessive inheritance, inbreeding was identified as an important driver of the expression and occurrence of the trait through increased homozygosity and sharing of identical by descent (IBD) segments.
The occurrence of anomalous coat color in a small and severely inbred population illustrates how reduced genetic variation, resulting from genetic drift and inbreeding, can shape phenotypic traits by exposing rare recessive genetic variants. The anomalous coat color observed in the population can therefore serve as an indicator for underlying genetic mechanisms driven by demographic history and constraints. Furthermore, the genetic constraints shaped by few founders, small population size, and isolation over several decades point to the importance of maintaining genetic diversity by facilitating gene flow and introduction of new genetic variation, but also how such vital immigration can bring about unforeseen side effects. Finally, these findings highlight the importance of genetic monitoring of small and isolated populations, which can provide a framework for linking demographic history and genetic mechanisms to address long-standing questions relating to the genetics and conservation of populations
