Exploring the affective, motivational and cognitive effects of pedagogical agent enthusiasm in a multimedia learning environment
Authors: Liew Tze Wei , Mat Zin Nor Azan , Sahari Noraidah 
Published: March 2017

AbstractIn a traditional classroom environment, instructor enthusiasm has been shown to enhance student’s emotion, affective perceptions, intrinsic motivation, and cognitive outcome. Additionally, emotional response theory argues that enthusiastic verbal and nonverbal cues of an instructor will induce positive emotional states in learners, which in turn, enact learners’ approach behaviours in the learning process. Therefore, should a pedagogical agent convey enthusiastic behaviours in a multimedia learning environment? Literature and theoretical reviews offer two competing views. The first view, based on emotional response theory, predicts that enthusiastic verbal and nonverbal cues of a pedagogical agent can induce higher positive emotions in learners, which in turn, enhance affective perceptions, intrinsic motivation, and cognitive outcome. However, the second view, based on cognitive load theory, suggests that pedagogical agent enthusiasm may increase extraneous cognitive load (additional processing in the mind), which negatively impact emotion, affective perceptions, intrinsic motivation, and cognitive outcome. To investigate the effects of agent enthusiasm, seventy-two university freshmen interacted with either an enthusiastic agent or a neutral agent (operationalized through vocal tones, facial expression, gestures, and remarks) that simulates the instructional role of a virtual tutor that delivers narrative demonstrations on how to predict the outputs of C-Programming algorithms. The results of our study showed that pedagogical agent enthusiasm significantly enhanced emotion, intrinsic motivation, affective perceptions, and cognitive outcome. Moreover, mediation analyses revealed that the facilitating effects of agent enthusiasm on intrinsic motivation, affective perceptions of the learning environment, and affective perceptions of the pedagogical agent were fully mediated by a learner’s positive emotion, thus demonstrating that the framework of emotional response theory can be applied to learner-agent interaction in a multimedia learning environment. Implications and suggestions for future research related to pedagogical agent enthusiasm are discussed in this paper.
Pigment characterisation in Australian rock art: a review of modern instrumental methods of analysis
Authors: Stuart B. H. , Thomas P. S. 
Published: March 2017

Abstract
The many thousands of Aboriginal rock art sites extending across Australia represent an important cultural record. The styles and materials used to produce such art are of great interest to archaeologists and those concerned with the protection of these significant works. Through an analysis of the mineral pigments utilised in Australian rock art, insight into the age of paintings and practices employed by artists can be gained. In recent years, there has been an expansion in the use of modern analytical techniques to investigate rock art pigments and this paper provides a review of the application of such techniques to Australian sites. The types of archaeological information that may be extracted via chemical analysis of specimens collected from or at rock art sites across the country are discussed. A review of the applicability of the techniques used for elemental analysis and structural characterisation of rock art pigments is provided and how future technological developments will influence the discipline is investigated.
Mg status in inflammation, insulin resistance, and associated conditions
Authors: da Rocha Romero Amanda Batista , da Silva Lima Fabiana , Colli Célia 
Published: March 2017

AbstractMagnesium (Mg), an essential ion for the human body, is involved in various enzymatic reactions, particularly those related to energy transfer, storage, and transport. Longitudinal studies show that hypomagnesaemia (Mg serum concentration <0.75 mmol/L) and Mg dietary inadequacy (daily intake < EAR (Estimated Average Requirement) for age/gender) are conditions related to metabolic disorders of the immune and cardiovascular system and often occur in obese and diabetic individuals. Poor eating habits, reduced Mg content in food and water are the main causes of the decrease in Mg intake by the general population. In clinical practice, the serum concentration of this mineral is the most widely used marker for diagnosing deficiency. However, the serum concentration does not reflect the nutritional Mg status since it can be maintained by mobilization of body storage, mainly the bone. Thus, the use of serum concentration as the only routine biomarker of Mg status may hinder the diagnosis of Mg deficiency. In clinical and experimental research, different methods for Mg status assessment are proposed (plasma, erythrocyte, urine), but they are seldom used in clinical routine. In some countries (such as USA and Brazil) the average daily Mg dietary ingestion of more than 60% of the adult population is lower than the Estimated Average Requirement for age and gender, and these data are not too different for individuals with chronic non-communicable diseases. It is unclear whether it is an actual reduction of Mg consumption or if the recommendations are overestimated. If we assume that the recommendations are correct, the question is if this condition constitutes a risk factor for chronic diseases or the hypomagnesemia described in some diseases is a consequence of physiopathological changes. This review has the latest information of human and animal studies about Mg status evaluated from plasma, erythrocyte and urine, dietary inadequacy, and its relation to inflammation and to components of metabolic syndrome.

Abstract
Mononuclear phagocytes are present in skin and mucosa and represent one of the first lines of defense against invading pathogens, which they detect via an array of pathogen-binding receptors expressed on their surface. However, their extraction from tissue is difficult, and the isolation technique used has functional consequences on the cells obtained. Here, we compare mononuclear phagocytes isolated from human skin using either enzymatic digestion or spontaneous migration. Cells isolated via enzymatic digestion are in an immature state, and all subsets are easily defined. However, cells isolated by spontaneous migration are in a mature state, and CD141 cross-presenting DCs (cDC1) are more difficult to define. Different pathogen-binding receptors are susceptible to cleavage by blends of collagenase, demonstrating that great care must be taken in choosing the correct enzyme blend to digest tissue if carrying out pathogen-interaction assays. Finally, we have optimized mononuclear phagocyte culture conditions to enhance their survival after liberation from the tissue.
Experimental development of low-frequency shear modulus and attenuation measurements in mated rock fractures: Shear mechanics due to asperity contact area changes with normal stress

Published: March 2017

Reservoir core measurements can help guide seismic monitoring of fluid-induced pressure variations in tight fractured reservoirs, including those targeted for supercritical [Formula: see text] injection. We have developed the first seismic-frequency “room-dry” measurements of fracture-specific shear stiffness, using artificially fractured standard granite samples with different degrees of mating, a well-mated tensile fracture from a dolomite reservoir core, as well as simple roughened polymethyl methacrylate (PMMA) surfaces. We have adapted a low-frequency (0.01–100 Hz) shear modulus and attenuation apparatus to explore the seismic signature of fractures and understand the mechanics of asperity contacts under a range of normal stress conditions. Our instrument is unique in its ability to measure at low-normal stresses (0.5–20 MPa), simulating “open” fractures in shallow or high-fluid-pressure reservoirs. The accuracy of our instrument is demonstrated by calibration and comparison with ultrasonic measurements and low-frequency direct shear measurements of intact samples from the literature. Pressure-sensitive film was used to measure real contact area of the fracture surfaces. The fractured shear modulus for most of the samples shows an exponential dependence on the real contact area. A simple numerical model, with one bonded circular asperity, predicts this behavior and matches the data for the simple PMMA surfaces. The rock surfaces reach their intact moduli at lower contact area than the model predicts, likely due to more complex geometry. Finally, we apply our results to a linear-slip interface model to estimate reflection coefficients and calculate S-wave time delays due to the lower-wave velocities through the fractured zone. We find that cross-well surveys could detect even well-mated hard-rock fractures, assuming the availability of high-repeatability acquisition systems.
Factors Relating to Late Presentation of Patients With Breast Cancer in Area 2 KwaZulu-Natal, South Africa
Authors: Čačala Sharon R. , Gilart José 
Published: March 2017

Purpose Patients with breast cancer (BC) in Area 2 KwaZulu-Natal, South Africa, often present with advanced disease. We performed a review of the patients’ sociodemographic characteristics and their reasons for late presentation to identify what changes could be made to improve time to presentation. Patients and Methods Fifty women with T1, T2, T3, or T4 BC were assessed for sociodemographic data. Patients in T3 and T4 groups were asked to provide reasons for late presentation. Results Of 172 patients, 50 had T2, T3, or T4 BC, and 22 had T1. Age ranged from 23 to 100 years (average, 56 years). There was no significant difference in age for different tumor sizes. The average size of a T1 tumor was 1.8 cm; T2, 3.6 cm; T3, 11.4 cm; and T4, 14.8 cm. Regarding education, 19% of patients had never attended school (T1, 5%; T2, 12%; T3, 22%; T4, 32%), and 19% had completed their education (finished 12th grade). The average education level was 6th grade. Patients with larger tumors had less education ( P < .05). Of the patients who lived in rural areas, 41% had T1, 52% had T2, 66% had T3, and 78% had T4 tumors ( P < .01). Patients with larger tumors were associated with having less electricity in their homes than patients with smaller tumors ( P < .05). Patients presented with a variety of symptoms. A breast lump was the presenting complaint in 96% of T1 and T2, 68% of T3 and 32% of T4; with a nipple or skin change, 2% of T3 and 8% of T4; because their families insisted, 6% of T3 and 8% of T4; because of pain, 24% of T3; and because of pain with malodorous smell, 50% of T4. Patients’ reasons for late presentation were fear (40%), not aware of disease severity (40%), fear of losing a breast (40%), referral problems (34%), financial problems (8%), and transportation problems (6%). Approximately 33% sought medical help from traditional healers, and 65% regularly attended clinics. Conclusion Patients who presented late often lived in rural areas with fewer amenities (such as having no electricity in their homes), less education, and poor understanding of BC. Pictorial information about BC needs to be introduced to people who live in rural communities, and opportunistic screening needs to be provided at local clinics.
whoishRisk – an R package to calculate WHO/ISH cardiovascular risk scores for all epidemiological subregions of the world

Published: March 2017

The World Health Organisation and International Society of Hypertension (WHO/ISH) cardiovascular disease (CVD) risk assessment charts have been implemented in many low- and middle-income countries as part of the WHO Package of Essential Non-Communicable Disease (PEN) Interventions for Primary Health Care in Low-Resource settings. Evaluation of the WHO/ISH cardiovascular risk charts and their use is a key priority and since they only existed in paper or PDF formats, we developed an R implementation of the charts for all epidemiological subregions of the world. The main strengths of this implementation are that it is built in a free, open-source, coding language with simple syntax, can be downloaded from github as a package (“whoishRisk”), and can be used with a standard computer.
Exercise effectiveness of arteriovenous fistula maturation in chronic renal patients: A systematic review with meta-analysis

Published: March 2017

Aims: The purpose of this research is to evaluate the effectiveness of upper limb exercises to improve arteriovenous fistula maturation in patients with chronic kidney disease. Methods: A bibliographic search was carried out from February to August 2015 in the following databases: PUBMED, CINAHL, Web of Science, SCOPUS, LILACS, SCIELO and CENTRAL. Results: Three studies were included, involving 134 participants (total). According to the total effect estimation, a mean difference of 0.36 (-0.95–1.67) was found for vein diameter, meanwhile a mean difference of 107.87 (-3.90–219.64) was found for blood flow. Conclusion: It was not possible to determine the effect size of the treatment due to a high bias risk of all included studies. Given this, the available evidence is still insufficient to support the prescription of upper limb exercises in order to improve arteriovenous fistula maturation. Therefore, randomised and controlled clinical trials monitored by methodological rigour should be developed in order to verify if the AVF maturation process can be evidenced through exercise.
The hum of the Earth: From geomythology to epistemological leaps via art (draft for a future art practise)
Authors: Mikkola Anna 
Published: March 2017

Abstract
The Hum is a phenomenon that only very few people experience, but for those this invasive low frequency humming, rumbling or droning noise is highly intrusive. The cause for the phenomenon has been widely speculated over four decades, and it looks like there are many valid reasons for it. In 2015 scientific researchers found out that one instance of the Hum originates from the movement and pressure of giant, slow-moving waves. The Hum acts as an example in this article to discuss art’s potential to deal with the human relation to what is alien to human perception – namely, natural phenomena. To deal with the alien, humans construct geomyths, which are as important in binding the human with nature as science – perhaps even more. I will bring in Steve Goodman’s work on vibrational force to bring depth into the Hum as a phenomenon. By looking more closely into Iain Hamilton Grant’s work on Schelling and Ray Brassier’s work on Sellars I will investigate what kind of methods art might learn from geomythology and epistemology for coexisting with that which is alien to human perception.
When diet and exercise are not enough: How Theatre for Health helps resolve gaps in current programmes addressing obesity
Authors: Fisher Teresa A. 
Published: March 2017

Abstract
This article analyses the use of Theatre for Health as another programming approach to understanding and addressing the issue of obesity with adults. The author reviews current health and wellness programmes that focus on obesity and examines the potential for Theatre for Health to address programming gaps. A series of Theatre for Health workshops on bodies and weight designed and facilitated by the author between 2010 and 2016 is examined as an example of how Theatre for Health can help participants recognize and explore the sociocultural and emotional experiences that shape their beliefs about and behaviours relating to weight. The author shares key findings from an analysis of participants’ workshop participation, discusses challenges to the work, and offers suggestions for moving the work forward.
Beyond Pascal’s vanity of painting: or translating reality
Authors: Besnard-Scott Laurence 
Published: March 2017

Abstract
In one of his Pensées, Blaise Pascal denounces the vanity of painting for claiming to reproduce reality. In an age dominated by works of art that privilege the process of production, Pascal’s statement seems rather outdated. However, this article aims to show to what extent Pascal’s thought still drives us to reflect upon the nature of art; more specifically, how it can be used as a contestation of art as objective representation, and how it connects to contemporary art through writings on art and translation theory.
Drawing pareidolia: Journal extracts reflecting on practice-based research
Authors: Monahan Elizabeth 
Published: March 2017

Abstract
Our way of seeing and interpreting the visual world are a highly personal and diverse experience. These are the cornerstones of image making, the results of which can offer thought-provoking glimpses into another person’s view of the world, and can make us question our own. This reflective article grapples with the process of creating drawn interpretations of visual perception, specifically that of facial pareidolia, and attempts to share this ‘felt’ process. However, although an interest in pareidolia initiated the study, other concerns emerge: the process of looking and how drawing can navigate issues of time, space and movement.
MIMA’s approach to participation and audience development: A new understanding of museums in the information age
Authors: Villegas Camila 
Published: March 2017

Abstract
This article explores the challenges and opportunities brought upon museums by recent changes in the way people communicate with each other and with institutions. To further understand the nuances of this issue, this study looks at the way the Middlesbrough Institute of Modern Art (MIMA) has proposed to evolve with the information age. Many theorists agree that the Internet has sparked a revolution for the consumer, who now has new power and a desire to participate. In the art world, this translates into a call to co-create and challenge expert culture. MIMA’s path evidences that catering to these challenges while staying relevant in the eyes of funding institutions is a tough balancing act. However, this new vision for museums paints a promising picture: an opportunity for museums to take an even more relevant part in politics.
Art of the revolution: The urgency to create in political turmoil
Authors: Swais Petra 
Published: March 2017

Abstract
This essay discusses the recent Egyptian revolution and the surge of art which materialised and consequently contributed to the fuelling and documenting of the demonstrations. Considering the urgency and immediate need to create in a coming together of a people, this is analysed against Arendt’s theories of revolution and reflected against ‘Opera from Balconies’, an experimental theatrical project which took place spontaneously in various neighbourhoods in cities across the Egyptian Delta. It discusses echo of hope through collective engagement from the space of Tahrir Square to the domestic neighbourhoods of the ‘Opera from Balconies’ project.

Looking at representations of race and ethnicity across Nordic film history, I explore how cinema has reflected and subverted ethnic stereotypes against the backdrop of shifting political and economic landscapes.
Educational policy and mentorship: Transforming classroom practice and assessment in the art class
Authors: Filbin Deborah N. , Boughton Douglas G. 
Published: March 2017

Abstract
This paper is a narrative about the ways in which mentorship received by a high school art teacher through her Ph.D. program enabled her to reconstruct student assessment strategies to satisfy the demands of state imposed requirements for the review of teacher effectiveness. The context of the narrative take place in the wake of the PERA legislation (Performance Evaluation Review Act) implemented in Illinois in 2016. The assessment dilemma faced by the teacher was the expectation of administration to provide assessment data derived from inappropriate testing formats. The narrative traces the development of the teacher’s response to these demands and the ultimate resolution of the assessment problem achieved through her engagement with her doctoral program.
Psychoanalysis in Build-A-Bear-Workshop®: Lacanian and Kristevan perspectives
Authors: Hetrick Laura J. , Livingston Susan B. 
Published: March 2017

Abstract
One assistant professor and one doctoral candidate discuss their first hand qualitative investigation of a Build-A-Bear Workshop® experience, as well as share the theoretical work that has informed their interpretations of the Workshop as a site of the abject. Two concepts of psychoanalysis that will be employed in this paper are Lacanian desire and Kristevan abject. We begin with quick overviews of desire and the abject and then briefly describe how they help us analyse and understand the phenomenon of visiting a Build-A-Bear Workshop®. These perspectives are cursory and presented as avenues for future research. We conclude with a reflection on the research process and what we have learned from working together.
Mentoring as a duoethnographic exhibition: Our journey as art museum researchers
Authors: Love Ann Rowson , Eudy Victoria 
Published: March 2017

Abstract
The study of curation is a growing research area moving away from solitary creative activities such as curating exhibitions into more participatory and collaborative endeavours (Love and Villeneuve 2016; Smith 2012; O’Neill 2012). In keeping with this evolving idea of curation, we employed duoethnographic dialogue to explore and co-curate our mentor-mentee experiences as an exhibition nestled within the cultural boundaries of art museum education and higher education. With objects guiding and rooting the discussion, our exhibition includes such themes including ‘Finding a Comfort Zone’, ‘Co-writing’ and ‘The Emerging Scholar and Edu-curator’. Throughout the article we also encourage the reader to consider his or her own mentor–mentee relationships through the exhibition themes as well as the potential for duoethnographic curation, and encourage participation.
Mentoring: To ease one into something, something not yet one’s own
Authors: O’Donoghue Donal , Lenz Kothe Elsa , Thomas Kate , Berard Marie-France , Smith Blake , Ryoo Anna 
Published: March 2017

Abstract
This article uses a conversation as the point of departure for considering the nature, qualities and scope of mentorship, and what mentorship does, enables and denies within academic relationships. Six art education colleagues gather to explore concepts, potentialities, places and practices of mentoring in a face-to-face interaction that leads to further musings through a collective writing process. From tweets to personal testimony, this subjective and philosophical unfolding negotiates possible routes for navigating some of the complexities, qualities, emotional landscapes, and interactions of the mentor/mentee relationship. We aim to challenge our own assumptions and expectations by asking critical questions, creating openings for other ways of knowing, and imagining what else might become possible when mentorship helps ease someone into something not yet one’s own.
