Constituting the workplace curriculum

Abstract: This paper advances some bases for a workplace curriculum. These are premised on conceptions of curriculum as intents directed to individuals’ progression towards full and effective workplace performance, yet whose enactment is shaped by workplace factors and is ultimately experienced by workers as learners. So whether the intentions will be realized is likely premised on the support (affordances) for their enactment by interests within the workplace. Workplace affordances, like those in educational institutions, emphasize the role that the norms and social practices that comprise workplaces play in regulating individuals’ engagement in and learning through work. The degree to which these affordances invite, structure, support, and guide participation, and are likely to engage workers in the kinds of thinking, acting, and learning required for effective workplace performance, is important for developing effective vocational practice. The conception of an ideal curriculum directed towards full participatio...

Earth-abundant Ni2P/g-C3N4 lamellar nanohydrids for enhanced photocatalytic hydrogen evolution and bacterial inactivation under visible light irradiation

Abstract: Photocatalysts made of earth-abundant elements are highly desired for photocatalytic H2 evolution as well as bacterial inactivation without requirement of noble metal (i.e. Pt, Ag). In this study, nickel phosphide (Ni2P) was used as a nonprecious co-catalyst to couple with metal-free g-C3N4 based on Z-scheme type of electron transportation model. The exfoliation of bulk g-C3N4, the in-situ synthesis and anchoring of Ni2P nanoparticles onto the g-C3N4 nanosheets were achieved in one-step by a hydrothermal method without adding any surfactants or templates. The optimized Ni2P/g-C3N4 lamellar nanohydrids exhibited remarkably enhanced visible-light-driven photocatalytic activity for H2 evolution and bacterial inactivation without noble metal loading, and the obtained activity is approximately 22 and 10 times higher than that of pure g-C3N4, respectively. The Ni2P was proposed to effectively trap the photo-generated e− via a Z-scheme type of route, thus significantly promoting the e−-h+ separation and subsequent reduction of protons to generate H2. The bacterial inactivation was found to undergo a direct h+ oxidation process, and therefore the trapping of e− by Ni2P also facilitated h+ accumulation, leading to enhanced bacterial inactivation efficiency. This study demonstrates a proof-of-concept for constructing all-earth-abundant photocatalysts without any noble metal elements for both energy production and environmental application.

Explaining the Deterrence Effect of Human Rights Prosecutions for Transitional Countries

Abstract: Human rights prosecutions have been the major policy innovation of the late twentieth century designed to address human rights violations. The main justification for such prosecutions is that sanctions are necessary to deter future violations. In this article, we use our new data set on domestic and international human rights prosecutions in 100 transitional countries to explore whether prosecuting human rights violations can decrease repression. We find that human rights prosecutions after transition lead to improvements in human rights protection, and that human rights prosecutions have a deterrence impact beyond the confines of the single country. We also explore the mechanisms through which prosecutions lead to improvements in human rights. We argue that impact of prosecutions is the result of both normative pressures and material punishment and provide support for this argument with a comparison of the impact of prosecutions and truth commissions, which do not involve material punishment.
