Revisiting the dimensionality of subjective task value: Towards clarification of competing perspectives

Expectancy-value researchers have described the components of subjective task value in multiple ways, leading to multiple competing structural representations of subjective task value data. The purpose of this study was to examine these competing multidimensional factor structures by comparing correlated factor, hierarchical, and bifactor representations of both confirmatory factor analysis and exploratory structural equation modeling (ESEM) models across three theoretical conceptualizations of subjective task value. Results indicate that, in an undergraduate life science learning context (n = 334), the best representation for subjective task value data was a bifactor ESEM model that allowed for the disentangling of general and specific variance of general subjective task value, specific value beliefs, and specific costs. Full measurement invariance of the retained structure across continuing generation and first-generation students was found, and no differential item functioning was found across gender. General subjective task value and specific opportunity cost significantly and positively predicted achievement and specific utility value significantly and negatively predicted achievement, providing support for the criterion-related validity of the general and specific factors for predicting achievement outcomes.     

Study on properties of residue-residue contacts in protein

INTRODUCTION Recognition of protein folding from aminoacid sequence is a challenging task. The structureand stability of proteins from different fold aremainly dictated by inter-residue interactions. In-formation on the distribution of contacts shown by20 amino acid residues can be used to predict thefolding type of each protein (Chan and Dill, 1998;Zhang and Kim, 2000; Gromiha, 2001; Gromihaand Selvaraj, 1999; Miyazawa and Jernigan, 1985;1996; Bahar et al., 1997; McDonald and …     

农民数字化贫困的结构性成因分析

本文基于丰富的田野研究数据、经验和理论,界定了数字化贫困的范畴,提炼出数字化贫困的八个核心要素,即数字化物质实体、数字化服务、数字化心理、数字化能力、数字化努力、数字化社会规范、数字化社会支持和数字化影响。根据数字化贫困现象的典型特征,以八个核心要素为维度识别并描述了中国农村社会中常见的数字化贫困人群:物质匮乏者、数字化文盲、脆弱的贫困者、孤独的贫困者、懒惰的贫困者、抵触的贫困者、徒劳无益者以及数字化赤贫者。在界定结构性贫困的前提下,将经济资本、文化资本、社会资本和政治资本作为四个结构性强的成因,并依据田野数据论证其存在的事实,分析它们对上述常见的不同数字化贫困类型的多重作用机理。本研究强调数字化贫困的个体性成因不容忽视,但更需要关注结构性成因,并对如何更好地实现数字化脱贫提出战略思考。表3。参考文献29。     

英语句法问题二则

教学过程中遇到的两则英语句法问题值得商榷。其一,“It was so windy that it was only with a tremendous effort were we able to pitch a tent”一句中的倒装,采取句型转换的方法,运用全息律、结构边界律、转换守恒律等规律,依据传统语法学说,可推断并说明该句中的倒装不仅绝无必要而且应调整为正序。其二,“He progressed very quickly”一句中“progress”一词的运用,从名转动用、正向迁移等角度,可论证“progress”一词在该句中的运用并非词性与词义不统一。而且对名转动用这一客观语言现象,应从其赖以存在的深层机理,亦即其语义基础、语用推理和句法动因等角度作理论上的多维探析。     

Time to seize the digital evolution: Adoption of blockchain in operations and supply chain management among Malaysian SMEs

This study aims to investigate the effects of relative advantage, complexity, upper management support, cost, market dynamics, competitive pressure and regulatory support on blockchain adoption for operations and supply chain management among Small-Medium Enterprises (SMEs) in Malaysia. Unlike existing studies that employed linear models with Technology Acceptance Model or United Theory of Acceptance and Use of Technology that ignores the organisational and environmental factors, we adopted the Technology, Organisation and Environment Framework that covers the technological dimensions of relative advantage and complexity, organisational dimensions of upper management support and cost and environmental dimensions of market dynamics, competitive pressure and regulatory support. Empirical data from 194 SMEs were investigated and ranked using a nonlinear non-compensatory PLS-ANN approach. Competitive pressure, complexity, cost and relative have significant effects on behavioural intention. Market dynamics, regulatory support and upper management support were insignificant predictors. SMEs often lack resources for technological investments but faces same requirements for streamlining business processes to optimise returns and blockchain presents a viable option for SMEs’ sustainability due to its features of immutability, transparency and security that have the potential to revolutionise businesses. This study contributes new knowledge to the literature on factors that affect blockchain adoption and justifications were discussed accordingly.

Teachers’ conceptions of assessment: Comparing two inventories with Ecuadorian teachers

Teacher beliefs about the purpose of assessment matter to how assessment is implemented in classroom settings. Two different teacher conceptions of assessment inventories have originated separately in Spain and New Zealand. This study examined (a) the extent to which the models for each inventory could be recovered and (b) the relationship between inventories. Responses were obtained from 566 Ecuadorian primary and secondary teachers in two rounds of surveying. Results showed that with a few modifications both the Spanish and New Zealand models fit the data. Mean scores were strongest for improvement, caution, and societal control factors. Factor inter-correlations between the Spain and New Zealand models indicated that the teaching, certifying, and accounting domains were moderately correlated with accountability and improvement purposes, while societal control correlated with caution, and formative regulation correlated with irrelevance. These results are consistent with how teachers seem to conceive of assessment within strong examination systems.     

Key contributors: Ernst von Glasersfeld’s radical constructivism

This article reviews the significance of the contributions of Ernst von Glasersfeld to research in science education, especially through his theoretical contributions on radical constructivism. As a field shaper, Glasersfeld’s subversive ideas catalyzed debate in the science education community and fuelled transformation of many facets including research methods, ways of thinking about teaching and learning, curriculum, and science teacher education. Perturbations emanating from the debates on constructivism forged new pathways that led to the development and use of many of the sociocultural frameworks employed by authors in Cultural Studies of Science Education.

PDC钻头喷嘴倾角流场特性模拟研究

利用数值模拟的手段,在K-ε方程数学模型上计算封闭的N-S方程,对不同类型的PDC钻头喷嘴倾角组合进行了流场模拟。模拟结果表明:喷嘴倾角对PDC钻头的井底流场有明显的影响,不同的喷嘴倾角组合,井底流场特性不同,水力清岩的效果不同。保持中心喷嘴倾角一定,外围喷嘴倾角为20°~30°时,能使井底压力场、速度场达到最优。保持外围喷嘴倾角一定,中心喷嘴倾角为12°~22°时,能使井底压力场、速度场达到最优。
