Semiotising the student perception of learning outcomes in British higher education

This article presents a semiotic analysis of the student perception of learning outcomes in British higher education. It centres on three annotated images in Frank Furedi’s article “The Unhappiness Principles”, published in Times Higher Education in 2012. Drawing upon Peircean semiosis and iconicity, it provides a rhetoric-infused interpretation of the word–image complementarity exhibited in student participants’ written commentaries on the three images. This leads to a dialectical view of formative and summative assessment, in which process and product create each other through the same continuum of learning and teaching. In highlighting intellectualism as central to the ethnography of university life, this article argues that learner autonomy and the potential for transformation is deemed essential to the student experience in higher education.     

环境习惯法对少数民族地区环境法制建设的贡献——以青海果洛藏族自治州达日县和青海湟中县为例

将民族环境习惯法与国家法进行衔接和融合,既是少数民族地方环境法制建设的需要,也是民族环境习惯法现代化的合理进路。具体而言,三江源地区环境习惯法可以成为国家环境立法的来源,并有助于环境法律的实施,同时能够弥补环境立法的空缺。

Reciprocal Relationships between Teacher Ratings of Internalizing and Externalizing Behaviors in Adolescents with Different Levels of Cognitive Abilities

Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability.     

Population Pressures and the North–South Divide between the first century and 2100

This article examines the relationship between the populations of the more and less developed societies between the first century and 2100. Such an analysis reveals a changing dependency between the level of development (and GDP) achieved and population numbers between the first century and 1998. In relation to the past the article suggests a dynamic model for dividing the world into more and less developed areas. In relation to the present and the future it bases the population analysis on the developmental division of the world as published by one of the co-authors of this article. The article largely uses population estimates (with those referring to the past taken from Angus Maddison and those referring to the future from the most recent projections by the United Nations). Taking the 2013 UN projection as a model, it discusses three variants for demographic development in the North and South up to 2100. It argues that the more restrictive population growth variants of the UN projection predict a greater relative ‘Third Worldisation’ of the world than does the most dynamic projection.     

Development of a Novel Finger-Trigger Interface for Trigger Pull Measurement

Trigger pull is the force that needs to be exerted on the trigger to discharge a firearm. The measurement of trigger pull can assist in the evaluation of the safety, function, and manufacturing characteristics associated with a firearm during the forensic firearm examination process. Nonetheless, the accuracy and uncertainty of trigger pull measurements may be affected by the measuring device, test procedure, and environmental conditions. In this work, an innovative finger-trigger interface device was developed to facilitate accurate trigger pull measurements. The idea was to reduce the variation related to the position of the measurement device on the trigger in existing measuring methods and devices. Three force sensors based on different technologies were initially evaluated. While two of the three sensors failed to produce data, the miniature capacitive plate sensor exhibited high precision and a linear response over the range of typical trigger pulls. To examine the effects of the finger-trigger interface on trigger pull measurement, different sensor housing prototypes were designed in silico and 3D printed for the construction of three finger-trigger interface devices. The performance of each finger-trigger interface device was evaluated by measuring the trigger pulls of several selected firearms and comparing the data to a previously published study. Our preliminary results demonstrated the novel finger-trigger interface device offered a new way to measure trigger pull in situ with acceptable accuracy and precision.     

Corporate policy entrepreneurship and cross-boundary strategies: How a private corporation champions mobile healthcare payment innovation in China?

The private nature of corporate actors does not necessarily preclude them from contributing to public interest. When business strategies and genuine public motivation are favorably aligned, corporate actors from the private sector can also drive public sector innovations. For a private corporation, policy entrepreneurship inherently entails crossing not only the public–private boundary but also various policy domains. This study formulates five propositions to characterize the cross-boundary strategies of corporate policy entrepreneurship, a distinct form of policy entrepreneurship in a developing authoritarian state. The case study of mobile healthcare payment innovation in China finds that the corporate entrepreneur used a series of cross-boundary strategies adeptly that eventually made the innovation not only adopted in one locality but also rapidly diffused nationwide. These strategies were not used in isolation or in a pure stepwise fashion but appeared to be recursive and interactive, suggesting the dynamic nature of corporate policy entrepreneurship in a multilevel governance system. More studies could be done to further examine strategies and processes of other forms of policy entrepreneurship in various national and sectoral settings.     

Diffusion models over the life cycle of an innovation: A bottom-up and top-down synthesis approach

The diffusion models tend to be tested individually in isolation and remain the same over time for the studied innovations in the literature. Moreover, there is growing interest to learn from other countries in our current age of globalization. Therefore, this paper chooses the innovation of public resources trading platforms in China to fulfill above literature gaps. We have examined key events and the issuances of related laws and regulations by Chinese governments. Our contributions are twofold: (a) Our analysis and results show that the diffusion models evolve over the different stages of a life cycle of an innovation, contrasting to the literature results that diffusion models remain the same for their studied innovations. Due to major diverse characteristics among different adopter categories over a life cycle of an innovation, we argue that it is appropriate and necessary to apply different diffusion models on different adopter categories, which is missing in the current literature. (b) We find a first bottom-up and then top-down synthesis approach as an effective, efficient diffusion process for both fitting local needs (i.e., effective) and adopting innovations rapidly nationwide (i.e., efficient).
