The Impact of Physical Distancing in the Pandemic Situation: Considering the Role of Loneliness and Social Brain

The new normal has made social distancing a new way of experiencing sociality. Social neuroscience has for a long time been concerned with studying the beneficial effects of social relationships, of physical contact. It is known that physical contact activates neurophysiological processes that reduce the perception of discomfort and even physical pain. So in the absence of physical contact, our social brain may be modulated differently when we are with others. But what could be the long-term effects of this normality? This mini-review focuses on highlighting with the support of social neuroscience evidence such as isolation, distancing can affect people’s health

Drums, "Jazz," and resistance: the subversive acts of Max Roach

Max Roach (1924–2007) is a figure who not only made significant contributions to music, but also played a major role in challenging racist power structures and the bigoted hegemonic thought of many bourgeois white Americans. This paper aims to analyze Roach’s musical and non-musical works of protest, as well as his “symbolic resistance” in unintentionally subversive actions, to determine the impact and “efficacy” of his work in influencing social change. How can a notion of efficacy be determined in protest music? How does the intent and goal of the artist affect the reception of their protest music? What actions have had a verifiable and provable impact in fighting prejudicial, exploitative, and oppressive systems? These broader questions are explored as they relate to the work of Max Roach. The diversity of approach and intent in protest music among artists highlights the complexities when considering Roach’s works of protest and “symbolic resistance.” The paper first establishes context by discussing several notable works of twentieth-century American protest music up to the 1960s. By such time, Roach had become a prominent musical innovator and Black rights activist. Thorough review of Roach’s career makes it possible to identify key actions and musical contributions with complex social implications, which I refer to as “symbolic resistance.” This includes Roach rejecting his professor’s assertion that he had improper drumming technique, the power in the act of drumming and its loudness, and a dismantling of racist ideas of “primitivism” in playing drums. On the other hand, Roach was a revolutionary figure with lifelong involvement in protest. I focus mostly on Roach’s article, entitled “What ‘Jazz’ Means to Me,” as one of his best-known non-musical works of protest. Lastly, this paper presents a detailed and methodical analysis of the album We Insist!: Max Roach’s Freedom Now Suite. I attempt to determine the intent behind these works of protest, and ultimately argue how such works have been received by audiences. Roach fought oppression and discrimination based on race, yet relevant economic critique and class struggles are often overlooked by critics. Throughout the paper, connections are made between race and class struggles, both of which were significant during Roach’s lifetime. Roach is among the most influential musicians in the history of American jazz, having made unparalleled contributions to jazz drumming, protest music, the fight against racist structures, and representation through the performance of various Black musical expressions

Exploring Multivariate Profiles of Psychological Distress and Empathy in Early Adolescent Victims, Bullies, and Bystanders Involved in Cyberbullying Episodes

(1) Background: Adolescents may be involved in cyberbullying as victims, perpetrators, or to a lesser extent, victim–perpetrators simultaneously. The present research investigated differences between participants acting in different bullying roles—namely, bully, victim, or bully/victim—and bystander roles—namely, defending, passive bystander, and passive/defending; (2) Methods: We used multivariate analysis of covariance to determine how, in the same individuals, direct involvement in cyberbullying episodes compares to participating in them as by-standers in relation to both psychological distress and empathy; (3) Results: Both victims and bully/victims were found to be at increased risk for suicidal ideation, internalizing and externalizing symptoms, and emotional dysregulation compared with students who were neither victims nor perpetrators of cyberbullying episodes. Additionally, victims showed higher empathy scores when compared with bullies and bully/victims. All bystander roles showed increased emotional dysregulation compared with uninvolved students, but no differences emerged on other psychological distress measures. Finally, defending bystanders showed increased cognitive empathy. (4) Conclusions: During early adolescence, the direct experience of cyberbullying, as a bully or a victim (or both), show a stronger association with psychological distress than the mere participation in cyberbullying as a witness, regardless of the witness acting defensive toward the victim, or passive. However, both cyberbullying and bystanding roles provide a similar (small) explicative power over empathy variables

Efforts for the Correct Comprehension of Deceitful and Ironic Communicative Intentions in Schizophrenia: A Functional Magnetic Resonance Imaging Study on the Role of the Left Middle Temporal Gyrus

Deficits in social cognition and more specifically in communication have an important impact on the real-life functioning of people with schizophrenia (SZ). In particular, patients have severe problems in communicative-pragmatics, for example, in correctly inferring the speaker’s communicative intention in everyday conversational interactions. This limit is associated with morphological and functional alteration of the left middle temporal gyrus (L-MTG), a cerebral area involved in various communicative processes, in particular in the distinction of ironic communicative intention from sincere and deceitful ones. We performed an fMRI study on 20 patients with SZ and 20 matched healthy controls (HCs) while performing a pragmatic task testing the comprehension of sincere, deceitful, and ironic communicative intentions. We considered the L-MTG as the region of interest. SZ patients showed difficulties in the correct comprehension of all types of communicative intentions and, when correctly answering to the task, they exhibited a higher activation of the L-MTG, as compared to HC, under all experimental conditions. This greater involvement of the L-MTG in the group of patients could depend on different factors, such as the increasing inferential effort required in correctly understanding the speaker’s communicative intentions, and the higher integrative semantic processes involved in sentence processing. Future studies with a larger sample size and functional connectivity analysis are needed to study deeper the specific role of the L-MTG in pragmatic processes in SZ, also in relation to other brain areas

Effect of a laser-ablated micron-scale modification of dental implant collar surface on changes in the vertical and fractal dimensions of peri-implant trabecular bone

Background. Marginal bone loss (MBL) represents an important indicator of peri-implant health and the measure of its level is considered a determining factor in the evaluation of the quality of survival. Aim of this study is to compare radiographic changes in the fractal and mesial/distal vertical dimensions of peri-implant trabecular bone of dental implants with a laser-ablated micron-scale modication (LAM) of collar surface after a 5-year follow-up period. Materials and methods. Thirty-four implants with LAM of collar surface (test group = TG) and 31 implants without LAM of collar surface (control group = CG) were placed in 45 non-smoking, periodontally healthy patients. Fractal and vertical dimensions of peri-implant trabecular bone were measured by comparing radiographs taken immediately after prosthesis delivery with those taken 3 years and 5 years after functional loading. Results. At the end of the 5-year follow-up, the MBL in the TG was 0.87±0.21 and 0.75±0.25 mm at the mesial and distal aspects, respectively, while a MBL of 2.05±0.25 mm at the mesial aspect and 2.01±0.34 mm at the distal site was recorded in the CG. A statistically significant difference was noted. In the TG the mean fractal dimension before loading was 1.4213±0.0525. It increased significantly to 1.4329±0.0479 at 3 years after loading and remained almost stable at 5 years after loading (1.4327±0.0291). In the CG the mean fractal dimension before loading was 1.4119±0.0414. It increased significantly to 1.4282±0.0324 at 3 years after loading and decreased significantly to 1.4111±0.0624 at 5 years after loading. At the end of the follow-up, differences between both study groups were statistically significant. Conclusions. The increased fractal dimension and the reduced MBL around TG implants after 5 years of functional loading indicates a positive effect of a laser-ablated micron-scale modication of collar surface on peri-implant trabecular bone remodeling
