Co-evolution of physical and social technologies in clinical practice: The case of HIV treatments

In this paper, we investigate the interplay of clinical knowledge and technological capabilities in the recent development of HIV/AIDS treatments and offer qualitative and quantitative evidence from the empirical setting of Italian practice. The study contributes to the literature on the co-evolution of physical and social technologies in medical innovation by showing how professional guidelines, systematic evaluative research and local coordination mechanisms contribute actively to the resolution of the uncertainty that surrounds technological advances, while leaving room for largely discretional therapeutic choices. The resulting variety in implementation strategies improves health outcomes, but may reduce productive efficiency.     

Phonological processing and emergent literacy in younger and older preschool children

Phonological awareness, phonological memory, and phonological access to lexical storage play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPA) in 389 3-, 4-, and 5-year-old children. Confirmatory factor analysis supported the validity of each PPA as separate from general cognitive ability and separate from each other. Multigroup structural equation modeling (SEM) with mean structure demonstrated that older preschoolers have better developed latent PPA than younger preschoolers but that the structure of PPA is equivalent. RAN was found uniquely associated with letter knowledge and text discrimination in younger preschoolers, and PA was found uniquely associated with word reading skills in older preschoolers. Finally, general cognitive ability was only indirectly associated with emergent literacy via PPA. These results highlight the importance of PPA in the early literacy development of English-speaking preschool children.

我国女子长跑运动的国际竞争力研究

长跑是一种体能与技术兼备的竞技项目,随着竞技运动水平不断提高,长跑运动的短跑化趋势日趋明显。从众多运动现象发现长跑运动的核心竞争力并非耐力,而是运动员在比赛中的变速和冲刺能力。核心竞争力不足是影响我国女子长跑运动员运动水平提高的主要问题。长跑运动技术和力量速度素质是制约核心竞争力的两大主要因素。摆动和送髋技术是影响步幅的主要技术原因,也是影响长跑竞争力的核心技术。     

‘This could be our reality in the next five to ten years’: a blogpost platform as an expectation generation device on the future of insurance markets

William James (1919) characterises hypotheses as either live or dead. A hypothesis is live when it is taken into account as a ‘real possibility’. We follow James’ suggestion to not attribute intrinsic properties to hypotheses, but rather investigate how they came into being and look at the effects they generate. Expectations of digital technologies are a topic of vivid debate in the insurance industry. Before these expectations can become ‘live’, they have, in the first place, to be generated by market devices. We investigate how the reinsurance blogpost platform Open Minds functions as an ‘expectation generation device’ on the future of insurance markets. Combining Beckert’s work on the role of fictional expectations with the pragmatist turn in sociology of markets, we propose to study ‘expectation generation devices’, provoking expectations on economic markets. In our empirical analysis, we demonstrate the explicit fictional character of the Open Minds contributions, and analyse how a contained space of openness is generated to provoke expectations. We demonstrate how Open Minds can become live through circulation to other expectation generation sites in the insurance industry and beyond. We conclude by reflecting on the importance of expectation generation devices as a particular type of market devices.
