One proactive approach to increasing student engagement in schools is implementing Positive Behavior Intervention and Support (PBIS) strategies. PBIS focuses on prevention and concentrates on quality-of-life issues that include improved academic
achievement, enhanced social competence, and safe learning and teaching environments. This study is a replication of a study that investigated the combination of active supervision, precorrection, and explicit timing. The purpose of the study was to decrease student problem behavior, reduce transition time, and support maintenance of the intervention in the setting. Results show that active supervision, precorrection, and explicit timing decreased student problem behavior, decreased the duration of transitions in two instructional periods, and the intervention was maintained in the setting. Implications, limitations, and future research are discussed.

The present study deals with an AFCA (Adaptive Fuzzy Control Algorithm) for an Euler-Bemoulli approximation of a two-dimensional version of a cantilever beam-like orthogonal tetrahedral space truss. Transient disturbances, modeled as a unit impulse, excite all the modes of the beam. The resulting transverse displacement at the free end of the beam and its corresponding rate are observed by sensors placed there, and active control of the beam is provided by a collocated force actuator.
A design methodology, based on fuzzy logic which assumes no a priori knowledge of plant dynamics, for the closed-loop control algorithm results in relatively quick settling times, low overshoots and dying out of vibration within a few seconds. The control algorithm is enhanced and made much faster by eliminating the need of repeatedly solving the set of differential equations of motion of an emulated dynamic vibration absorber. When the control force is turned off after a mere 15 seconds, almost all the vibrational energy is dissipated as the beam returns to its undisturbed state throughout its length. In addition, the performance of the AFCA is insensitive to varying initial conditions. To examine the robustness of the control system to changes in the temporal dynamics of the cantilever beam, the transient disturbance response to a considerably perturbed plant is simulated. The Young's modulus of the beam was raised as well as lowered by 60%, substantially perturbing the natural frequencies of vibration compared to the nominal plant. The AFCA provided similar settling times and rates of vibrational energy dissipation, satisfying the aim of plant model independence.

OBJECTIVE: Damage to hair from UV exposure has been well reported in the literature and is known to be a highly complex process involving initiation via absorption of UV light followed by formation and propagation of reactive oxygen species (ROS). The objective of this work was to understand these mechanisms, explain the role of copper in accelerating the formation of ROS and identify strategies to reduce the hair damage caused by these reactive species.
METHODS: The location of copper in hair was measured by Transmission electron microscopy–(TEM) X-ray energy dispersive spectroscopy (XEDS) and levels measured by ICP-OES. Protein changes were measured as total protein loss via the Lowry assay, and MALDI ToF was used to identify the biomarker protein fragments. TBARS assay was used to measure lipid peroxide formation. Sensory methods and dry combing friction were used to measure hair damage due to copper and UV exposure and to demonstrate the efficacy of N,N’ ethylenediamine disuccinic acid (EDDS) and histidine chelants to reduce this damage.
RESULTS: In this work, a biomarker protein fragment formed during UV exposure is identified using mass spectrometry. This fragment originates from the calcium-binding protein S100A3. Also shown is the accelerated formation of this peptide fragment in hair containing low levels of copper absorbed from hair during washing with tap water containing copper ions. Transmission electron microscopy (TEM) X-ray energy dispersive spectroscopy (XEDS) studies indicate copper is located in the sulphur-poor endo-cuticle region, a region where the S100A3 protein is concentrated. A mechanism for formation of this peptide fragment is proposed in addition to the possible role of lipids in UV oxidation. A shampoo and conditioner containing chelants (EDDS in shampoo and histidine in conditioner) is shown to reduce copper uptake from tap water and reduce protein loss and formation of S100A3 protein fragment. In addition, the long-term consequences of UV oxidation and additional damage induced by copper are illustrated in a fourmonth wear study where hair was treated with a consumer relevant protocol of hair colouring treatments, UV exposure and regular shampoo and conditioning.
CONCLUSIONS: The role of copper in accelerating UV damage to hair has been demonstrated as well as the ability of chelants such as EDDS and histidine in shampoo and conditioner products to reduce this damage.
Despite the increased popularity of online tools for remote teamwork and meetings, moderated collaborative activities between multiple users in early conceptual design stages, such as brainstorming sessions, are yet not well supported. In this paper, we introduce All4One, a networked system that enables multiple remote users to participate in a moderated visual sketching session. Each participant can independently draw and share sketches using a tablet, and a moderator uses a set of tangible tools to arrange and manipulate sketches that are displayed in real-time on a whiteboard. We present our prototype in detail and the results from a workshop study simulating a brainstorming session with designers who tested the system in practice. Results show several usage patterns and the potential of All4One for use in early design stages, and the importance of the role of the moderator as the facilitator of the design process. The paper concludes by identifying weaknesses and strengths of the current system and possible directions for future work.
A formula has been developed that defines the relativity of time in a novel approach. In the present paper, this is particularized for cases of temporary dilation due to speed and gravity. Using the previous equation, that serves as basis of the “Time Theory” proposed, an interpretation of the nature of black holes, their formation, growth, and dimension can be developed. Which ultimately leads to an alternative understanding of mass and energy.
The purpose of this study is to plan and operate design-workshops based on project-based learning (PBL), and examine their educational value for students. The PBL workshop encour- ages direct participation from students and produces educational value, and it is important to raise the interest level of workshops to elicit proactive participation. The workshop in this study was carried out over two weeks in January 2017 at Korea’s Yonsei University. The workshop was composed of eight teams of students from three countries, including Korea, China, and Japan, and the course was primarily divided into two sessions. The workshop participants examined in this thesis were notably satised with the elements of the course meant to garner interest. In the questionnaire results, participants also indicated that they obtained ample educational value through the workshop. An important element of the workshop was to connect the participants with businesses, which is also an important component of design education. Despite this, participants expressed a relatively lower level of satisfaction com- pared to other elements of the workshop. The results and analysis of this study will hopefully become a meaningful resource for educators when designing workshops in the future.
Case studies are discussed, from Northumbria University’s practice-led Centre for Design Research (CfDR) that demonstrate how visualising concepts and designs through digital animation can enable effective communication of ideas and interactions, which in turn enables creative leaps in thinking, understanding and decision-making. Animation is a tool that can unlock the comprehension into what is and what could be. This paper reflects on a number of collaborative projects between the CfDR and several scientific communities, demonstrating and focusing in particular on the process of visualisation, designing digital animations to communicate complex processes, ideas and interactions. An approach and understanding has been developed about how to effectively communicate potentially complex, scientific and technical concepts for the benefit of the client and the end user, in particular the lay audience whose knowledge of the subject may be limited or non-existing.
Findings indicate that the process of constructing simple digital animated stories becomes a learning process for both designer and client. Critical discussions during collaborative meetings develop shared understandings: helping clients to think more creatively about communication (appreciating the benefits of manipulating a truth to position to waylay contextual confusion), and making implicit knowledge belonging to the client explicit to the designer. It is important to state that this negotiation is more effective when the designer is a layperson with respect to the complex implicit knowledge of the client. During these collaborative conditions the untangling of complex ideas have achieve the a-ha moments in the animations’ audiences.
Background: Role of apolipoprotein (apo) A-II on metabolism of high density lipoproteins (HDLs) is unknown.
Results: Conformational changes of apoA-I, the major apolipoprotein of HDL, caused by apoA-II in discoidal HDL are confined to two regions of apoA-I.
Conclusion: Interactions between the two major apolipoproteins in discoidal HDL are site specific.
Significance: Functional implications of HDL complexes will significantly benefit from such structural information.
The challenges facing many small nonprofit organizations are increasing at a greater rate than the internal capacities of many within this sector are able to address effectively. This situation has small nonprofits questioning their sustainability and ability to deliver their services in the long term. Often these small nonprofit organizations are working within a business model and communications paradigm that has remained unchanged for decades and one which is proving no longer effective in attracting awareness, engagement, and support. Many of these organizations are facing a critical failure requiring significant business model innovation to achieve both their short-, mid- and long-term goals. Design thinking is an avenue for nonprofits to achieve business model innovation by developing new, unique concepts supporting an organization’s viability and the processes for bringing those concepts to fruition. This case study outlines the design thinking process applied to business model innovation for a small, 22-year old, nonprofit approaching critical business failure.
The environment in which patients (need to) reside has a great influence on their wellbeing (Ulrich, 1991). That is why introducing ‘Design for Wellbeing’ is key in the design of palliative environments. People in the last phase of their life become more receptive to environmental stimuli. From our perspective, this triggers design to become even more relevant in such contexts. People’s search for subjective well-being (SWB) has promoted a change in vision in the design of new products, services and environments, with a focus not only on material properties, but also on the personal values that trigger actions that can contribute to people’s SWB. Such considerations contribute also to proposing answers to the question of how design can support people to have a meaningful life and ‘be well’ in the best possible way, according to the circumstances.
The purpose of this paper is firstly, if design for wellbeing can be performed in the context of palliative care, and secondly, how research could be set up in such a precious context. A thorough literature review will be performed to answer these questions. The value of this study lies in aiming to try to enable terminally ill patients and people from their immediate surroundings to cope with these events via design, and to stimulate people to be able to perform activities that they like (most) and which contribute to their SWB.
This presentation suggests a new transversal image of thought to grasp the creation of an ethical series of events in which architectural history/theory coursework engages in multi-educational rhizomatic ‘plateaus’. It does so by combining the philosophies and notions of impersonality and effects of French post-structuralist Gilles Deleuze, with that of Simone Brott (an Australian architect), as the basis for a cartographic analysis of the empirical subjectivity that works as a set of impersonal effects to reformulate the architectural history/theory coursework.
Discussion of the likely impacts of climate change on archives is significantly deficient in the archival profession. Archives hold rare and unique materials that are irreplaceable and institutional adaptation to climate change is critical to the survival of these resources. The earliest effects of climate change are likely to be increased weather events that threaten the physical safety of holdings. Hurricanes, floods, and fires pose particular risks to archives due to potential damage to buildings as well as from limitations of local infrastructure to rapidly respond to disasters. Disaster preparedness for archives needs to include planning responses to a wide variety of situations that threaten holdings. As societies begin to adapt to climate change, archivists should consider how values of sustainability and resiliency might inform archival practice.
When considering the future of archives, it is essential to consider the role of archivists. Archives have suffered from a multi-decade cycle of poverty that stunts their ability to provide adequate care for records and services for users. The role of archival interventions carried out by archivists is often overlooked and invisible to users and the general public. Well-managed and useful archives require archivists to oversee their care. Archivists play a critical role in responding to concerns about digital cultural heritage loss, but their marginalization from the public sphere remains a significant challenge.

This paper presents the results of a research based Living Lab experience, where people participate together as users, researchers, stakeholders and collaborators working to effect change to improve social inclusion and social participation for persons with functional difficulties. The Rehabilitation Living Lab in the Mall (RehabMall) transforms an urban shopping mall into an interdisciplinary, multi-sectorial research platform that supports multiple projects investigating what constitutes an accessible and inclusive environment for people with physical, sensory and cognitive disabilities. We present an overview of the RehabMALL Living Lab, the contexts of the project and the project meta-analysis to present the salient issues emerging from the projects that were done. Grounded in a design research approach, and inspired by the Ecological Systems Theory of Bronfenbrenner (1979), the investigations conducted focus on subjective and inter-subjective experiences within understanding obstacles and facilitators that frame how people experience going to the mall, and how the physical, cognitive and virtual environments that support these activities might be better served. Disability is defined within the framework of the “World Health Organization’s International Classification of Functioning (WHO, 2003). The overview of the project is presented with particular attention to the various collaborations and partnerships created alongside the issues that emerge in terms of results, and how people might be better served when public spaces are designed with their input and within a perspective of universal design.
