Doing sensitive research: what challenges do qualitative researchers face?

Abstract: As health researchers we need to investigate a wide range of topics to enhance our understanding of the many issues that affect health and well-being in today's society. Much of the health research...

Plot-scale evidence of tundra vegetation change and links to recent summer warming.

Abstract: Temperature is increasing at unprecedented rates across most of the tundra biome(1). Remote-sensing data indicate that contemporary climate warming has already resulted in increased productivity ov ...

EV-TRACK: transparent reporting and centralizing knowledge in extracellular vesicle research

Abstract: We argue that the field of extracellular vesicle (EV) biology needs more transparent reporting to facilitate interpretation and replication of experiments. To achieve this, we describe EV-TRACK, a crowdsourcing knowledgebase (http://evtrack.org) that centralizes EV biology and methodology with the goal of stimulating authors, reviewers, editors and funders to put experimental guidelines into practice.

Culture, gender, and self: A perspective from individualism-collectivism research.

Abstract: Individualism and collectivism are often equated with independent vs. interdependent, agentic vs. communal, and separate vs. relational self-construals. Although these same concepts have been used to characterize both cultural and gender differences, a perspective of cultural evolution suggests it is unlikely. A division of labor within society may produce gender differences, but this cannot explain cultural differences. A study of self-construal involving 5 cultures (Australia, the United States, Hawaii, Japan, and Korea) shows that differences between these cultures are captured mostly by the extent to which people see themselves as acting as independent agents, whereas gender differences are best summarized by the extent to which people regard themselves as emotionally related to others.

Covalent Cross-Links in the Cell Wall.

Abstract: In meristematic and differentiating cells, walls have to withstand osmotically generated turgor pressures that may reach values around 3 to 10 bar (0.3-1 MPa) (Carpita and Gibeaut, 1993; Cosgrove, 1993). Walls must be constructed so as not to fail under these conditions. The aggregate strength of noncovalent forces between wall polymers appears to make this possible. There is little evidence that covalent cross-linking between wall polymers is necessary to achieve this stability (see Talbott and Ray, 1992, for a discussion). The results with 2,6-dichlorobenzonitrile-adapted tomato and tobacco cells in suspension culture indicate that although the cellulose-xyloglucan network in these walls is greatly reduced, the cells remain viable under normal osmotic conditions (Shedletzky et al., 1992). In these adapted cells the integrity of the walls appears to be dependent on increased amounts of Ca2\"-bridged pectates. The altered walls have a lower tensile strength, but their porosity is the same as for walls of nonadapted cells. The situation is somewhat different in the case of barley, a graminaceous monocotyledon. Here, the adapted cells have elevated glucuronoarabinoxylan and (1--3,1--4)-f-glucan contents and a lowered cellulose content (Shedletzky et al., 1992). In addition, there is an increase in ester-linked phenolic acids, especially PCA, and an increase in polysaccharides released after esterase treatment. Covalent cross-linking could be involved and extension might involve transesterification. Walls must not only resist turgor pressure, they must also allow wall expansion during cell growth. Cosgrove (1993) has discussed a mechanism by which stress relaxation in
