Photoelectrocatalytic Degradation

O2˙− played a crucial role in the photoelectrocatalytic degradation of BPB by the prepared GR/β-CD. Cl− marginally promoted the degradation of BPB and chlorinated intermediates were generated.

Programming Skills

Programming tasks are an important part of teaching computer programming as they foster students to develop essential programming skills and techniques through practice.  The design of educational problems plays a crucial role in the extent to which the experiential knowledge is imparted to the learner both in terms of quality and quantity. Badly designed tasks have been known to put-off students from practicing programming. Hence, there is a need for carefully designed problems. Cellular Automata programming lends itself as a very suitable candidate among problems designed for programming practice. In this paper, we describe how various types of problems can be designed using concepts from Cellular Automata and discuss the features which make them good practice problems with regard to instructional pedagogy. We also present a case study on a Cellular Automata programming exercise used in a MOOC on Test Driven Development using JUnit, and discuss the automated evaluation of code submissions and the feedback about the reception of this exercise by participants in this course. Finally, we suggest two ideas to facilitate an easier approach of creating such programming exercises.

Monuments are protagonists in many historical narratives. They “tell” fascinating stories of past times and past heroes and “advise” us to commemorate and reminisce. But who is actually doing the telling and to whom? How are the stories formed? In monuments the past and present, memory and history, meet in a complex way and form a structure of meanings reflecting the narratives and values of the so-called imagined community. Discursive and narrative practices play a crucial role in the formation and production of the meanings of monuments.

This chapter explores how an engineering consulting company creates, manages, and reuses knowledge within its projects. It argues that the informal transfer and reuse of knowledge plays a more crucial role than formal knowledge in providing the greatest benefit to the organization. The culture of the organization encourages a reliance on networks (both formal and informal) for the exchange of tacit knowledge, rather than utilizing explicit knowledge. This case study highlights the importance of understanding the drivers of knowledge transfer and reuse in projects. This will provide researchers with an insight into how knowledge management integrates with project management.

The Relationship

Abstract Sharing-economy firms have opposed the application of antidiscrimination law to their transactions. At the same time, these firms have heralded their ability to achieve antidiscrimination aims without the force of law, and have adopted various measures to address discrimination. This Article documents and assesses these measures, focusing on the relationship between law and norms. Relying on the sharing economy as a case study, this Article shows how law can play a crucial role in spurring antidiscrimination efforts by firms that it does not regulate, but also how antidiscrimination law might nonetheless be undermined by these voluntary efforts.

The increased influx of refugees in 2015 has led to challenges in transition and destination countries such as Germany, Sweden and Denmark. Volunteer-led initiatives providing urgent relief played a crucial role in meeting the needs of arriving refugees. The work of the volunteers in central stations and transition shelters was mainly organised with the help of Facebook, in terms of both inward and outward communications. This article examines the role of social media for civic participation drawing on Swedish volunteer initiatives that emerged in the context of the migration crisis in 2015 as a case study. Theoretically, this article provides an analytical framework, including power relations, technological affordances, practices and discourses, which helps shed light on the interrelation between social media and civic participation.

Despite their seeming reluctance to engage in the politics of the now, historians have a crucial role to play as witnesses to climate change and its attendant social injustices. Climate change is a product of industrialization, but its effects are known in different geographical and temporal scales through the compilation and analysis of historical narratives. This essay explores modes of thinking about disasters and temporality, the Anthropocene, and the social production of risk – set against a case study of the Korean DMZ as a site for historical witnessing. Historical methods are crucial if we are to investigate deeply the social processes that have produced climate change. A “slow disaster in the Anthropocene” approach might show the way forward.

Myths provide hagiographic and iconographic accounts of the gods, which shape rituals that are performed in cults associated with these gods. In the realization of iconographies and ritualization of narratives in myths, material objects play an active role. This article examines the pattern of worship in the cult of the Ah Pehs, a group of Underworld gods whose efficacy lies in the promise of occult wealth, and focuses on the material aspects such as offerings and paraphernalia associated with these gods. Though ritual texts and scriptures are absent in the Ah Peh cult, symbols in the form of material objects play a crucial role. These objects are also considered as synecdoche for the gods in certain cases. The first part of this paper presents a case study of the autonomous ritual of “Burning Prosperity Money”, which reveals the cycle of occult exchange between gods and devotees. The second part involves an imagery analysis of the material objects central to the cult, and argues that in the system of reciprocity with the gods, material objects common to the everyday life are reinterpreted and enchanted with a capitalist turn, resulting in the development of occult economies within the local Chinese religious sphere.

AbstractIn this article, we introduce the effect of “constructional contamination”. In constructional contamination, a subset of the instances of a target construction deviate in their realization, due to a superficial resemblance they share with instances of a contaminating construction. We claim that this contaminating effect bears testimony to the hypothesis that language users do not always execute a full parse while interpreting and producing sentences. Instead, they may rely on what has been called “shallow parsing”, i. e., chunking the utterances into large, unanalyzed exemplars that may extend across constituent borders. We propose several measures to quantify constructional contamination in corpus data. To evaluate these measures, the Dutch partitive genitive is taken under scrutiny as a target construction of constructional contamination. In this case study, it is shown that neighboring constructions play a crucial role in determining the presence or absence of the
