Previous researchers have demonstrated significant improvement in students’ conceptual understanding of basic physics using interactive engagement methods of instruction. In this study, the effects of interactive computerbased simulations and animations investigated in classroom on students' conceptual understanding of electrostatics. Two groups – one control and one experimental of students at third year undergraduate level were studied to determine the role of computer simulations and animations in the development of functional understanding of the concepts of force, field, and potential in electrostatics. While few misconceptions persisted, the overall results indicate that students seem to have acquired a good general understanding of these concepts using such package. This occurred mainly in the area of verbal, vector and diagrammatic representation of the abstract physics concepts involved in the study.

Assisted Instruction

The primary objective of this article is to discuss the role of Computer Assisted Instruction (CAI) at the undergraduate level via a survey of related literature and specific applications. CAI shares many features with other instructional modes, such as traditional classrooms and programmed instruction (PI). Many characteristics of learners affect their ability to learn and acquire new knowledge. An individual's subject-specific knowledge and general knowledge both affect comprehension. With regard to instructional design, system approaches are sometimes referred to as instructional development systems (IDS). An IDS embraces several major categories. These include a statement of goals, analysis, development of instruction, and evaluation and revision. General statements on CAI can be divided into the following areas: requirements, potential benefits, state of the art, problems, CAI as a factor in society, the roles of industry, education, and government, including the role of teacher. At least two educational requirements make CAI inevitable, i.e., the trend to individualized instruction and the growth in information to be acquired. Data processing and computer science involve the teaching of computer skills in relative isolation from other disciplines. Hence, the computer is the principal subject. Student problem solving and research is where the computer is used as a tool in some field outside computer science. A specific sphere of application is the subject. This article will relate these categories as they apply to an introductory computer concepts course taught at the undergraduate level. Another phase of this course is that it is accounting-oriented.

Interactive engagement curricula are successful in helping students develop conceptual understanding of physics principles and solve problems. However, another benefit of actively engaging students in the construction of their physics knowledge is providing them with an opportunity to engage in habitual “thinking like physicists”. Some examples of such thinking are: drawing a sketch before solving any physics problem, subjecting normative statements to experimental testing, evaluating assumptions, or treating each experimental results as an interval. We can help students develop these “habits of mind” if we purposefully and systematically engage them in the processes that mirror the processes in which physicists engage when they construct and apply knowledge. For such engagement to occur, we need to deeply re-conceptualize the role of experiments in physics instruction and their interaction with the theory. However, most importantly, we need to rethink the role of the instructor in the classroom.

Although ego-centered network data provide information that is limited in various ways as compared with full network data, an ego-centered design can be used without the need for a priori and researcher-defined network borders. Moreover, ego-centered network data can be obtained with traditional survey methods. However, due to the dynamic structure of the questionnaires involved, a great effort is required on the part of either respondents (with self-administration) or interviewers (with face-to-face interviews). As an alternative, we will show the advantages of using CASI (computer-assisted self-administered interview) methods for the collection of ego-centered network data as applied in a study on the role of social networks in substance use among college students.

This chapter identifies the content and scope of application of the EU prohibition of refoulement. Following the ‘cumulative standards’ approach, the analysis incorporates developments in international human rights law (IHRL) and international refugee law (IRL). Taking account of the prominent role of the ECHR and the Refugee Convention (CSR51) as sources of Article 19 CFR, these are the two main instruments taken in consideration. The scope of application of Articles 33 CSR51 and 3 ECHR will be identified in turns. Autonomous requirements of EU law will be determined by reference to the asylum acquis as interpreted by the CJEU. The main focus will be on the establishment of the territorial reach of EU non-refoulement. The idea that it may be territorially confined will be rejected. Drawing on the ‘Fransson paradigm’, a ‘functional’ understanding of the ‘implementation of EU law’ standard under Article 51 CFR will be put forward, as the decisive factor to determine applicability of Charter provisions. The implications of non-refoulement for the different measures of extraterritorial control considered in Part I will be delineated at the end.

Abstract The increase in calls for police reform following the death of George Floyd has led to renewed debate about social inequality and the role of policing in society. Modern bureaucratic police systems emerged from locally administered structures and Anglo-American policing models continue to be aligned, to varying degrees, with the political, socio-cultural, legal, and ideological aspects of contemporary liberal democratic society with its emphasis on democratic localism and decentralised accountability. However, at a time when society is reimagining itself and technology, government, and nations are radically re-shaping themselves, a critical question is whether there is a sufficiently common philosophical and conceptual understanding of policing to support its development rather than just a common understanding of police functions. This is profoundly important when considering the current calls for reform of policing in the USA and other western democratic states. The article argues that there is an urgent need to reconsider how we conceptualize policing and its relationship with social development.

Poly (ADP-ribose) polymerases (PARP) 1-3 are well-known multi-domain enzymes, catalysing the covalent modification of proteins, DNA, and themselves. They attach mono- or poly-ADP-ribose to targets using NAD+ as a substrate. Poly-ADP-ribosylation (PARylation) is central to the important functions of PARP enzymes in the DNA damage response and nucleosome remodelling. Activation of PARP happens through DNA binding via zinc fingers and/or the WGR domain. Modulation of their activity using PARP inhibitors occupying the NAD+ binding site has proven successful in cancer therapies. For decades, studies set out to elucidate their full-length molecular structure and activation mechanism. In the last five years, significant advances have progressed the structural and functional understanding of PARP1-3, such as understanding allosteric activation via inter-domain contacts, how PARP senses damaged DNA in the crowded nucleus, and the complementary role of histone PARylation factor 1 in modulating the active site of PARP. Here, we review these advances together with the versatility of PARP domains involved in DNA binding, the targets and shape of PARylation and the role of PARPs in nucleosome remodelling.

Abstract Background Signal fidelity depends on protein–protein interaction–‘hubs’ integrating cues from large interactomes. Recently, and based on a common secondary structure motif, the αα-hubs were defined, which are small α-helical domains of large, modular proteins binding intrinsically disordered transcriptional regulators. Methods Comparative structural biology. Results We assign the harmonin-homology-domain (HHD, also named the harmonin N-terminal domain, NTD) present in large proteins such as harmonin, whirlin, cerebral cavernous malformation 2, and regulator of telomere elongation 1 to the αα-hubs. The new member of the αα-hubs expands functionality to include scaffolding of supra-modular complexes mediating sensory perception, neurovascular integrity and telomere regulation, and reveal novel features of the αα-hubs. As a common trait, the αα-hubs bind intrinsically disordered ligands of similar properties integrating similar cellular cues, but without cross-talk. Conclusion The inclusion of the HHD in the αα-hubs has uncovered new features, exemplifying the utility of identifying groups of hub domains, whereby discoveries in one member may cross-fertilize discoveries in others. These features make the αα-hubs unique models for decomposing signal specificity and fidelity. Using these as models, together with other suitable hub domain, we may advance the functional understanding of hub proteins and their role in cellular communication and signaling, as well as the role of intrinsically disordered proteins in signaling networks.
