BACKGROUND: The breast tumor microenvironment regulates progression of ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC). However, it is unclear how interactions between breast epithelial and stromal cells can drive this progression and whether there are reliable microenvironmental biomarkers to predict transition of DCIS to IDC. METHODS: We used xenograft mouse models and a 3D pathomimetic model termed mammary architecture and microenvironment engineering (MAME) to study the interplay between human breast myoepithelial cells (MEPs) and cancer-associated fibroblasts (CAFs) on DCIS progression...

This paper proposes a new easy and fast 3D avatar reconstruction method using an RGB-D sensor. Users can easily implement human body scanning and modeling just with a personal computer and a single RGB-D sensor such as a Microsoft Kinect within a small workspace in their home or office. To make the reconstruction of 3D avatars easy and fast, a new data capture strategy is proposed for efficient human body scanning, which captures only 18 frames from six views with a close scanning distance to fully cover the body; meanwhile, efficient alignment algorithms are presented to locally align the data frames in the single view and then globally align them in multi-views based on pairwise correspondence...

Social isolation in older adults is a major public health concern. An embodied conversational agent (ECA) has the potential to enhance older adults' social interaction. However, little is known about older adults' experience with an ECA. In this paper, we conducted a pilot study to examine the perceived acceptance and utility of a tablet-based conversational agent in the form of an avatar (termed "digital pet") for older adults. We performed secondary analysis of data collected from a study that employed the use of a digital pet in ten older adults' homes for three months...

BACKGROUND: The Internet offers several new ways of developing, implementing, and disseminating evidence-based interventions for depression. METHODS: In this paper, we narratively synthesized the evidence showing that Internet-based therapies are effective in treating depression. RESULTS: In the past decade, a considerable number of psychological treatments have been developed for the treatment of depression and several hundreds of randomized controlled trials have been conducted, showing that these interventions are effective and that there are no major differences in effects between therapies...

BACKGROUND AND OBJECTIVES: Extensive research documents ubiquitous negative attitudes towards stuttering, but when and how they develop is unclear. This non-experimental, comparative study examined US and Turkish preschoolers to explore the origin of stuttering attitudes cross-culturally. METHOD: The authors compared stuttering attitudes of 28 US and 31 Turkish non-stuttering preschoolers on English and Turkish versions of experimental prototypes of the newly developed Public Opinion Survey on Human Attributes-Stuttering/Child (POSHA-S/Child)...

BACKGROUND: Studies reveal that most nurse preceptor preparation programs do not meet nurse preceptors' training needs. This study thus developed a nurse preceptor-centered training program (NPCTP) in Taiwan. METHOD: The ADDIE model was used for the instructional design. On the basis of the nurse preceptors' training needs assessment, the research team developed the NPCTP. Content was adopted from the authentic experiences of preceptors and new graduate nurses (NGNs) using interview data to make 81 videos with computer avatars and 10 live actor films...

BACKGROUND: Activity trackers are widely used by adults and several models are now marketed for children. OBJECTIVE: The aims of this study were to (1) perform a content analysis of behavioral change techniques (BCTs) used by three commercially available youth-oriented activity trackers and (2) obtain feedback describing children's perception of these devices and the associated websites. METHODS: A content analysis recorded the presence of 36 possible BCTs for the MovBand (MB), Sqord (SQ), and Zamzee (ZZ) activity trackers...

Recognizing actions of others across the whole visual field is required for social interactions. In a previous study, we have shown that recognition is very good even when life-size avatars who were facing the observer carried out actions (e.g. waving) and were presented very far away from the fovea (Fademrecht, Bülthoff, & de la Rosa, 2016). We explored the possibility whether this remarkable performance was owed to life-size avatars facing the observer, which - according to some social cognitive theories (e...

Joint attention - the ability to coordinate attention with a social partner - is critical for social communication, learning and the regulation of interpersonal relationships. Infants and young children with autism demonstrate impairments in both initiating and responding to joint attention bids in naturalistic settings. However, little is known about joint attention abilities in adults with autism. Here, we tested 17 autistic adults and 17 age- and nonverbal intelligence quotient-matched controls using an interactive eye-tracking paradigm in which participants initiated and responded to joint attention bids with an on-screen avatar...

Efforts to identify pharmaceuticals to treat heritable metabolic liver diseases have been hampered by the lack of models. However, cells with hepatocyte characteristics can be produced from induced pluripotent stem cells (iPSCs). Here, we have used hepatocyte-like cells generated from homozygous familial hypercholesterolemia (hoFH) iPSCs to identify drugs that can potentially be repurposed to lower serum LDL-C. We found that cardiac glycosides reduce the production of apolipoprotein B (apoB) from human hepatocytes in culture and the serum of avatar mice harboring humanized livers...

Gait control challenges commonly coincide with vestibular dysfunction and there is a long history in using balance and gait activities to enhance functional mobility in this population. While much has been learned using traditional rehabilitation exercises, there is a new line of research emerging that is using visual stimuli in a very specific way to enhance gait control. For example, avatars can be created in an individualized manner to incorporate specific gait characteristics. The avatar could then be used as a visual stimulus to which the patient can synchronize their own gait cycle...

The extent to which you adapt your grammatical choices to match that of your interlocutor's (structural priming) can be influenced by the social opinion you have of your interlocutor. However, the direction and reliability of this effect is unclear as different studies have reported seemingly contradictory results. We have operationalized social perception as the ratings of strangeness for different avatars in a virtual reality study. The use of avatars ensured maximal control over the interlocutor's behaviour and a clear dimension along which to manipulate social perceptions toward this interlocutor...

REVIEW
Elisabeth Paul, Dimitri Renmans
Whereas performance-based financing (PBF) is now developing fast in the health sector in low- and middle-income countries and is presented an innovative approach-concomitantly, subject to a separate research stream-it shares many features of the "managing for results" (MfR) and performance-based budgeting (PBB) currents that have existed for decades. In this paper, we first argue that PBF as currently developed in the health sector in low- and middle-income countries shares many features and thus can be viewed as an avatar of MfR and more precisely PBB...

PURPOSE: This study aimed to investigate the effect of different magnitudes of deception on performance and exercise-induced fatigue during cycling time-trial. METHODS: Following three familiarization visits, three females and eight males performed three 5 km cycling time-trials while following a simulated dynamic avatar reproducing either 100% (5K100%), 102% (5K102%) or 105% (5K105%) of the subject's previous fastest trial. Quadriceps muscle activation was quantified with surface electromyography...

Methodologies to image and quantify the activity of proteolytic enzymes have been developed in an effort to identify protease-related druggable pathways that are involved in malignant progression of cancer. Our laboratory has pioneered techniques for functional live-cell imaging of protease activity in pathomimetic avatars for breast cancer. We analyze proteolysis in the context of proliferation and formation of structures by tumor cells in 3-D cultures over time (4D). In order to recapitulate the cellular composition and architecture of tumors in the pathomimetic avatars, we include other tumor-associated cells (e...

Experiments revealing 'spontaneous' visual perspective-taking are conventionally interpreted as demonstrating that adults have the capacity to track simple mental states in a fast and efficient manner ('implicit mentalising'). A rival account suggests that these experiments can be explained by the general purpose mechanisms responsible for reflexive attentional orienting. Here, we report two experiments designed to distinguish between these competing accounts. In Experiment 1, we assessed whether reflexive attention orienting was sufficient to yield findings interpreted as spontaneous perspective taking in the 'avatar task' (Samson et al...

Taking as a starting point, this commentary proposes some issues regarding the diagnosis of Internet Gaming Disorder discussed in Kuss et al. (2016). In our opinion, the confusion in DSM-5 diagnosis could be due to the weak starting point in building the criteria. The criteria such as functional impairment and stability of the dysfunctional behavior are considered. It is suggested that avatar identification, playing motivations, and types of video games should be considered for diagnosis. The diagnostic process is highly influenced by social context and the rapid development of video game industry...

Black, Asian, and White participants (N = 210) created self-resembling avatars and engaged in peer-selection tasks during social events in the virtual world, Second Life, that were designed to simulate various types of resource competition. Participants in merit-based resource competition settings had less diversity in their peer groups compared to participants in settings where no resource competition was present, and Asian participants had lower preference for Black peers. Furthermore, these relationships were mediated by out-group discomfort...
