The co-ordinative practices of temporary organisations

Purpose: This paper aims to explore the necessary mechanisms for coordination in complex industrial networks which are temporary in nature, known as temporary organisations (TOs). Design/methodology/approach: The paper is based on two in-depth case studies conducted in the UK construction industry. Findings: The paper outlines the necessary mechanisms for coordination in TOs – referred to as “scaffolding practices” – which ensure consistency(stability in terms of thinking and action), consensus (agreement) and co-constitutiveness (personal pledges and commitments). Research limitations/implications: The study provides practical implications for situations where actors create temporary organisational specific logics. This “logic” helps explain how actors are able to undertake tasks of finite duration where members lack familiarity and have competing loyalties. Originality/value: The paper is novel in that it represents the first extant attempt to examine “temporary industrial organizations” where individuals from different (often competing) organisations collaborate on a task for a defined period and suggests how coordination may be achieved

Exploring critical media health literacy (CMHL) in the online classroom.

Critical media health literacy (CMHL) is concerned with identifying healthrelated messages in the media, acknowledging the potential effects on health behaviours, critically analyzing the content of the message, and the subsequent application of the message to one’s health behaviours (Levin-Zamir & Bertschi, 2018). This exploratory research examined the CMHL skills of students (n = 120) in an entry-level, online asynchronous health and wellness course, by examining their ability to think critically about health-related themes presented in news media articles online and apply course-based knowledge during a Twitter event. Employing a content analysis of tweets from the event, students were found to illustrate CMHL skills when interacting with peers on Twitter, more than when directly assessing online news media. The findings suggest that the course curriculum be altered to include CMHL skills, to better equip students with the ability to identify accurate health information in the media

Inhibition of \u3cem\u3eRhizobium etli\u3c/em\u3e Polysaccharide Mutants by \u3cem\u3ePhaseolus vulgaris\u3c/em\u3e Root Compounds

Crude bean root extracts of Phaseolus vulgaris were tested for inhibition of the growth of several polysaccharide mutants of Rhizobium etli biovar phaseoli CE3. Mutants deficient only in exopolysaccharide and some mutants deficient only in the O-antigen of the lipopolysaccharide were no more sensitive than the wild-type strain to the extracts, whereas mutants defective in both lipopolysaccharide and exopolysaccharide were much more sensitive. The inhibitory activity was found at much higher levels in roots and nodules than in stems or leaves. Inoculation with either wild-type or polysaccharide-deficient R. etli did not appear to affect the level of activity. Sequential extractions of the crude root material with petroleum ether, ethyl acetate, methanol, and water partitioned inhibitory activity into each solvent except methanol. The major inhibitors in the petroleum ether and ethyl acetate extracts were purified by C18 high-performance liquid chromatography. These compounds all migrated very similarly in both liquid and thin-layer chromatography but were distinguished by their mass spectra. Absorbance spectra and fluorescence properties suggested that they were coumestans, one of which had the mass spectrum and nuclear magnetic resonances of coumestrol. These results are discussed with regard to the hypothesis that one role of rhizobial polysaccharides is to protect against plant toxins encountered during nodule development

Identification of the Plasticity-Relevant Fucose-α(1−2)-Galactose Proteome from the Mouse Olfactory Bulb

Fucose-α(1−2)-galactose [Fucα(1−2)Gal] sugars have been implicated in the molecular mechanisms that underlie neuronal development, learning, and memory. However, an understanding of their precise roles has been hampered by a lack of information regarding Fucα(1−2)Gal glycoproteins. Here, we report the first proteomic studies of this plasticity-relevant epitope. We identify five classes of putative Fucα(1−2)Gal glycoproteins: cell adhesion molecules, ion channels and solute carriers/transporters, ATP-binding proteins, synaptic vesicle-associated proteins, and mitochondrial proteins. In addition, we show that Fucα(1−2)Gal glycoproteins are enriched in the developing mouse olfactory bulb (OB) and exhibit a distinct spatiotemporal expression that is consistent with the presence of a “glycocode” to help direct olfactory sensory neuron (OSN) axonal pathfinding. We find that expression of Fucα(1−2)Gal sugars in the OB is regulated by the α(1−2)fucosyltransferase FUT1. FUT1-deficient mice exhibit developmental defects, including fewer and smaller glomeruli and a thinner olfactory nerve layer, suggesting that fucosylation contributes to OB development. Our findings significantly expand the number of Fucα(1−2)Gal glycoproteins and provide new insights into the molecular mechanisms by which fucosyl sugars contribute to neuronal processes

Contagion and learning in business networks

The purpose of this study is to examine network learning through the application of contagion theories. The transmission of knowledge, sharing of resources, and facilitation of learning through contagion has interested both business-to-business and economic geography researchers. This study responds to calls in both research traditions for research into knowledge and learning at the level of an interfirm network. More specifically, it focuses on developing an understanding of how the contagion of knowledge and ideas and the co-ordination of activities within a network tales place. We achieve this by drawing upon research in both network relationships dynamics and learning processes to investigate the causal mechanisms that drive contagion. We focus on two types of contagion: contagion by cohesion (i.e. the presences and closeness of direct contact with others in the network), and contagion by structural equivalence (i.e. where influence is related to the structural patterns of relationships in the network). We also identify two key mechanisms that act as a barrier to such contagion: isolation and immunity. We explore the implications of these findings for network learning opportunities, specifically learning-by-doing, learning-by-using, and learning-by-interacting

Contingent factors affecting network learning

To increase understanding of the impact of individuals on organizational learning processes, this paper explores the impact of individual cognition and action on the absorptive capacity process of the wider network. In particular this study shows how contingent factors such as social integration mechanisms and power relationships influence how network members engage in, and benefit from, learning. The use of cognitive consistency and sensemaking theory enables examination of how these contingent factors influence the learning processes of two construction industry design teams embedded within more permanent home-organizational structures. A number of practical ways arise by which firms can facilitate organizational learning through their interactions with network partners. Enhancement of learning in and between organizations occurs when members are cognizant of the means by which they connect within a network to create shared meanings, and the way in which they forge ties and share expertise in the learning process they engage in
