Behaviorism, social learning, and exchange theory [PDF]

, 2006
book chapterBehaviorism focuses on learning and the way in which behavior is shaped by its antecedent conditions and consequences. In rejecting mentalistic constructs such as mind, consciousness, and other internal processes, behaviorism stresses the ...

Status and Expertise in the Structuring of Reciprocal Exchanges on Twitter: Replies, Retweets, and Mentions During National Diabetes Awareness Month

International Journal of Communication, 2020
Social media play an important role in health campaigns. Extending social exchange theory to online contexts, this study examines the structure of communicative exchanges among health organizations and a broader set of Twitter users, with a particular ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Application of Social Exchange Theory (SET) in Understanding Community Perception of Tourism Development: A Review Analysis

International Journal of Hospitality & Tourism Management
Social Exchange Theory (SET) has been widely recognised as a dominant framework for studying how communities evaluate the impact of tourism in terms of perceived costs and benefits. Understanding community perception is a central concern in tourism research, particularly in the context of sustainable development, because without a supportive host ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
