Att undervisa i hållbar utveckling - Relationellt perspektiv
- 2022
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Hur kan lärare arbeta med hållbar utveckling i en tid då globala kriser och klimatförändringar väcker både rädsla och oro? Och hur kan elever samtidigt känna hopp inför sin framtid och sitt vuxna liv? Dessa frågor är utgångspunkt för det utvecklings- och forskningsprojekt som utgör basen i denna bok. Du får följa med i berättelser som lärare och elever skapat tillsammans för att utveckla kunskap om social, ekologisk och ekonomisk hållbarhet. Boken redogör för de pedagogiska utgångspunkterna, men ger också rikligt med praktiska exempel på metoder och former för undervisning i och genom demokratiska och relationella förhållningssätt. Du får konkreta tips på hur du kan integrera hållbar utveckling i undervisningen. Såväl kritiska aspekter som lärdomar och möjligheter lyfts fram. I centrum står eleven och läraren utifrån det relationspedagogiska perspektivet. Att undervisa i hållbar utveckling: Relationellt perspektiv vänder sig till lärarstudenter och verksamma lärare i årskurs F-6. Bokens syfte är att inspirera, stödja och utgöra diskussionsunderlag i skolans arbete med miljöperspektivet och hållbar utveckling.

- Streptococcus pyogenes (group A streptococcus) causes a variety of diseases, including acute pharyngitis, impetigo, rheumatic fever and the streptococcal toxic shock syndrome. Moreover, S. pyogenes was responsible for the classical example of a nosocomial infection, the epidemics of puerperal fever (childbed fever) that caused the death of numerous women in earlier centuries. The most extensively studied virulence factor of S. pyogenes is the surface M protein, which inhibits phagocytosis and shows antigenic variation. Recent data indicate that many M proteins confer phagocytosis resistance because the variable N-terminal region has non-overlapping sites that specifically bind two components of the human immune system, the complement inhibitor C4b-binding protein (C4BP) and IgA-Fc. Concerning puerperal fever, molecular and epidemiological analysis suggests that the S. pyogenes surface protein R28 may have played a pathogenetic role in these epidemics. This article summarizes the properties of M protein and the R28 protein and considers a potential problem encountered in connection with the use of animal models for vaccine development.

- The M protein of Streptococcus pyogenes is a major bacterial virulence factor that confers resistance to phagocytosis. To analyze how M protein allows evasion of phagocytosis, we used the M22 protein, which has features typical of many M proteins and has two well-characterized regions binding human plasma proteins: the hypervariable NH2-terminal region binds C4b-binding protein (C4BP), which inhibits the classical pathway of complement activation; and an adjacent semivariable region binds IgA-Fc. Characterization of chromosomal S. pyogenes mutants demonstrated that each of the ligand-binding regions contributed to phagocytosis resistance, which could be fully explained as cooperation between the two regions. Deposition of complement on S. pyogenes occurred almost exclusively via the classical pathway, even under nonimmune conditions, but was down-regulated by bacteria-bound C4BP, providing an explanation for the ability of bound C4BP to inhibit phagocytosis. Different opsonizing antisera shared the ability to block binding of both C4BP and IgA, suggesting that the two regions in M22 play important roles also under immune conditions, as targets for protective antibodies. These data indicate that M22 and similar M proteins confer resistance to phagocytosis through ability to bind two components of the human immune system.

- All living cells require specific mechanisms that target proteins to the cell surface. In eukaryotes, the first part of this process involves recognition in the endoplasmic reticulum of amino-terminal signal sequences and translocation through Sec translocons, whereas subsequent targeting to different surface locations is promoted by internal sorting signals(1). In bacteria, N-terminal signal sequences promote translocation across the cytoplasmic membrane, which surrounds the entire cell, but some proteins are nevertheless secreted in one part of the cell by poorly understood mechanisms(2,3). Here we analyse localized secretion in the Gram-positive pathogen Streptococcus pyogenes, and show that the signal sequences of two surface proteins, M protein and protein F ( PrtF), direct secretion to different subcellular regions. The signal sequence of M protein promotes secretion at the division septum, whereas that of PrtF preferentially promotes secretion at the old pole. Our work therefore shows that a signal sequence may contain information that directs the secretion of a protein to one subcellular region, in addition to its classical role in promoting secretion. This finding identifies a new level of complexity in protein translocation and emphasizes the potential of bacterial systems for the analysis of fundamental cell-biological problems(4).

- This article focuses on patients' violence against caregivers. Several studies show that violence and threats within the health care setting are an increasing problem. Encounters that become violent have been the issue of many debates but the phenomenon is still not fully understood. It is important to understand the course of events in violent encounters, both for the sake of the patients and the caregivers' well-being. The aim of this study was to describe the essence of violent encounters, as experienced by nine patients within psychiatric care. Guided by a phenomenological method, data were analyzed within a reflective lifeworld approach. The findings explicate violent encounters characterized by a tension between "authentic personal" and "detached impersonal" caring. "Authentic personal" patients are encountered in an undisguised, straightforward, and open way, and they sense unrestricted respect that caregivers would show another human being. In these encounters violence does not develop well. However, in caring that is "detached impersonal," the encounters are experienced by the patients as uncontrolled and insecure. These encounters are full of risks and potential violence. Copyright © Taylor & Francis Group, LLC.
