The Neurosurgical Atlas: advancing neurosurgical education in the digital age

OBJECTIVEThe advent of the internet and the popularity of e-learning resources has promoted a shift in medical and surgical education today. The Neurosurgical Atlas has sought to capitalize on this shift by providing easily accessible video and online education to its users on an international scale. The rising popularity of social media has provided new avenues for expanding that global reach, and the Atlas has sought to do just that. In this study, the authors analyzed user demographics and web traffic patterns to quantify the international reach of the Atlas and examined the potential impact of social media platforms on the expansion of that reach.METHODSTwitter, Facebook, and Instagram metrics were extracted using each respective service’s analytics tool from the date of their creation through October 2019. Google Analytics was used to extract website traffic data from September 2018 to September 2019 and app data from January 2019 to October 2019. The metrics extracted included the number of platform users/followers, user demographic information, percentage of new versus returning visitors, and a number of platform-specific values.RESULTSSince the authors’ previous publication in 2017, annual website viewership has more than doubled to greater than 500,000 viewing sessions in the past year alone; international users accounted for more than 60% of the visits. The Atlas Twitter account, established in August 2012, has more than 12,000 followers, primarily hailing from the United States, the United Kingdom, Canada, and Saudi Arabia. The Atlas Facebook account, established in 2013, has just over 13,000 followers, primarily from India, Egypt, and Mexico. The Atlas Instagram account (established most recently, in December 2018) has more than 16,000 followers and the highest percentage (31%) of younger users (aged 18–24 years). The Atlas app was officially launched in May 2019, largely via promotion on the Atlas social media platforms, and has since recorded more than 60,000 viewing sessions, 80% of which were from users outside the United States.CONCLUSIONSThe Neurosurgical Atlas has attempted to leverage the many e-learning resources at its disposal to assist in spreading neurosurgical best practice on an international scale in a novel and comprehensive way. By incorporating multiple social media platforms into its repertoire, the Atlas is able to ensure awareness of and access to these resources regardless of the user’s location or platform of preference. In so doing, the Atlas represents a novel way of advancing access to neurosurgical educational resources in the digital age.

The binge-watcher’s journey: Investigating motivations, contexts, and affective states surrounding Netflix viewing

The growth of Internet-distributed TV services has transformed video consumption, enhancing the level of control that viewers have over what they watch. Along with the release of entire seasons of programming at once, this has led to the phenomenon of ‘binge-watching’, in which several episodes of a program are viewed in one sitting. This article presents the results of a novel exploratory study focused on 40 Netflix viewing sessions from 11 millennials in their homes. Methodologically, we employed a novel mixed-methods approach that combines objective data (collected through a browser extension) and subjective data (collected via questionnaires completed before and after viewing). This novel approach allowed us to describe the binge-watcher’s experience in a holistic fashion. Results suggest that binge-watching is an individual activity mainly performed at the end of the day to relax, for boredom relief purposes, or for escapism. Furthermore, a binge-watching session lasts for an average of 2 h and 10 min, and variations on binge-watchers’ affective states were identified after Netflix exposure. Participants’ levels of valence (unhappy–happy) significantly decreased after binge-watching; their positive affect values increased primarily after watching sci-fi, while their negative affect values decreased after watching comedy and slightly increased after watching drama. However, the levels of arousal (relaxed–stimulated) remained the same. This study extends our current understanding of binge-watching in terms of viewer motivations, how it affects their viewing experiences, and participants’ subjective affective states. The investigation contributes, thus, to a relatively new domain of research concerned with the understanding of binge-watching behavior of serialized TV fiction.

Experimental Evidence for Differences in the Prosocial Effects of Binge-Watched Versus Appointment-Viewed Television Programs

This study investigated the influence of television consumption patterns on changes in attitudes toward depicted social out-groups. Participants were randomly assigned to view six episodes of Amazon’s Transparent, a comedy-drama program about a family whose father comes out as a transgender woman, in either one 3-hr (“binge-watching”) session or six weekly half-hour (“appointment-viewing”) sessions. Across both groups, we found exposure to the narrative reduced anti-transgender prejudice. Counter to the predictions of the extended elaboration likelihood model and the entertainment overcoming resistance model, however, improvement in prejudice toward transgender people was not predicted by narrative or character involvement. Rather, reduction in prejudice was an outcome of viewing condition, such that those who viewed the program on a schedule of one episode per week exhibited lower levels of postexposure prejudice than those who binge-watched, and their attitudinal changes were more persistent 3 weeks later. Results are discussed in the context of the original elaboration likelihood model, proposing mechanisms for further testing.

Additional intraoral radiographs may change the judgment regarding the final position of orthodontic mini-implants

ABSTRACT Objective: This study aimed to assess if additional vertical bitewing (VBW) and/or occlusal (OC) radiographs may change initial judgment based only on periapical radiograph (PAR) about the final position of orthodontic mini-implants (OMI). Methods: Subjective and objective analyses were performed. Radiographic images of 26 OMI were divided into four groups: PAR, PAR+VBW, PAR+OC and ALL (PAR+VBW+OC). For subjective analysis, five observers were asked to assess if the position of OMI was favorable to its success, using questionnaires with a four-point scale for responses: 1= definitely not favorable, 2= probably not favorable, 3= probably favorable, or 4= definitely favorable. Each group containing sets of images was presented to them in four different viewing sessions. Objective evaluation compared horizontal distances between OMI tip and the root nearest to the device in PAR and VBW. Results: Most of observers (3 out of 5) changed their initial judgment based on PAR about OMI position when additional radiographs were analyzed. Differences between groups (i.e. PAR vs. PAR+VBW; PAR vs. PAR+OC; and, PARvs.ALL) were statistically significant for these observers. For those that changed their judgment about OMI position, confidence level could significantly increase, decrease or even be maintained, not indicating a pattern. There was no agreement for distances between OMI tip and the root nearest to the device in PAR and VBW. Conclusion: Considering the limitations of the study, it is concluded that additional radiographic images may change the judgement about OMI final position without necessarily increasing the degree of certainty of such judgment.

Becoming an English Teacher: A Historical-Cultural Study of the Interrelationship between Emotions and Pedagogical Practices inside the Classroom

This study aims to investigate the inter-relationship between the emotions experienced by a novice English teacher and her actions during a period of one semester of observed activities. The emotions are understood as higher mental functions that emerge in sociocultural contexts. As cultural products, they can develop and transform. Emotions also work as an internal organizer of our actions. In order to achieve the goal proposed it is used as data generation instruments: (i) experience narrative; (ii) oral life history interview; (iii) class recording followed by viewing sessions; (iv) interview on emotions. The results suggest that the participant’s emotions can be organized into four categories, related to her students, her practice, the pedagogical coordination, and to her own profession. The emotions experienced lead the teacher to do certain things that may or may not contribute to her professional development. The connotation of certain emotions in negative or positive depends on the context in which they emerge.
