ABSTRACTThis forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities. 相似文献

Purpose: There is a paucity of research investigating the expression of mitogen-activated protein kinases (MAPK) in chronically trained (CT) athletes. Thus, it is unclear how MAPK may contribute to performance and muscle adaptation in CT subjects. The purpose of this study was to determine MAPK total protein, and phosphorylated expression of extracellular signal-regulated kinases 1 and 2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38-MAPK (p38) between untrained, and chronically trained runners. Methods: Tissue samples were analysed from sedentary (SED; n?=?5) controls and chronically trained runners (CT; n?=?5). Resting muscle biopsy samples were analysed for total-MAPK – and ratio of phosphorylated/total (p-MAPK) – ERK1/2, JNK, and p38-MAPK via western blotting. Mann–Whitney U tests and effect sizes were utilized to determine differences in total MAPK protein content and phosphorylation status between SED and CT subjects. Results: There was no difference in total-MAPK expression between SED and CT (p?>?.05). p-p38-MAPK tended to be greater for CT compared to SED (p?=?.07). There were moderate effect sizes of decreased pERK/total-ERK (d?=??0.69) and increased pJNK/total-JNK (d?=?0.54) in CT compared to SED. There was a positive correlation between p-p38-MAPK/total-MAPK and the percentage of type I fibres (r?=?0.73, p?=?.016). Conclusion: Contrary to previous studies, chronic endurance training does not greatly influence total MAPK protein expression in chronically trained runners. However, resting phosphorylation of p38-MAPK may contribute to enhanced oxidative metabolism at chronically trained levels. These alterations are likely involved in the different physiological adaptations that occur following long-term training or at highly competitive levels. 相似文献

In New Zealand, Māori (indigenous New Zealanders) and Pacific students tend not to attain the same levels of educational success
as Pākehā (New Zealanders of European descent). Addressing this problem is a particular challenge in the sciences. The kaupapa
(values-base) of Te Rōpū Āwhina (Āwhina) is to produce Māori and Pacific professionals to contribute to Māori and Pacific
development and leadership through the creation of an inclusive off- and on-campus whānau (extended family) environment where
high expectations, aspirations and achievement, collective success, and reciprocity are normalised. This paper reviews theories
and practices of recruitment and retention relevant to Māori and Pacific students at tertiary level, presents the rationale
for Āwhina in the Faculties of Science and Architecture and Design at Victoria University of Wellington, and assesses the
impact of the whānau. Based on analyses of quantitative measures of student achievement, and biennial surveys of student responses
from the first 6 years of Āwhina, it is suggested that the results are consistent with improving Māori and Pacific graduate
and postgraduate achievement and retention. Potential implications for efforts to reduce disparities in tertiary education
in New Zealand and elsewhere are summarised. 相似文献
