Choosing the right imaging method in muscle hernias: musculoskeletal ultrasonography

Muscle hernia (MH) is a focal protrusion of muscle into the overlying subcutaneous tissue through an acquired or congenital facial defect. Herniation in the thigh muscles is not common and there are limited reports evaluating this pathology using ultrasonography (US). A 28-year-old amateur football player presented with a palpable mass on the anterior aspect of his right thigh. Sonographic examination demonstrated a MH through a fascial defect, which is called mushroom appearance. Based on the clinical and sonographic findings, the diagnosis of a MH in the rectus femoris muscle was established. Today, there is no doubt anymore on the role of musculoskeletal US in the field of sports injuries. Therefore, with its various advantages (non-invasive, practical and convenient, inexpensive, etc.), US is the key imaging method in the diagnosis of MHs.     

Intellectual roots of distance education: a progressive knowledge domain analysis

ABSTRACT

Distance education (DE) is a constantly evolving and advancing field, and as such, its intellectual network and dynamics need to be investigated and explored. In this regard, this study reviewed a total of 1685 articles and 51,940 references through social network analysis for a bibliometric examination of the DE field. The findings indicate that DE is an interdisciplinary field and part of mainstream education. The progressive knowledge domain analysis revealed that the intellectual roots of DE stem from generic social learning theories, after which DE-related theories began to emerge following the foundation of open universities. The research concludes that there was a paradigm shift that resulted from developments in online networked technologies in the 2000s, at which time DE started to gradually evolve into sixth generation ubiquitous DE.     

First Step to Success – a school/home intervention program for preventing problem behaviors in young children: examining the effectiveness and social validity in Turkey

This study examined the effectiveness of the First Step to Success (FSS) early intervention program for preventing antisocial behavior in Turkey. Participants included 24 students, their teachers and parents from four K–8 elementary schools. The experimental group included 12 targeted students (four kindergarten, four first-grade and four second-grade students) who received the intervention. Both quantitative and qualitative methods were carried out by using a pre-posttest experimental design. Results indicated that there were significant decreases in problem behaviors and significant increases in social skills and academic competence of targeted students. In addition, teachers and parents reported significant positive changes in problem behaviors and social skills of their children. Most teachers and parents were highly satisfied with the program. Limitations of the study and directions for future research are discussed.     

Digital identity formation: socially being real and present on digital networks

Social networks have become popular communication and interaction environments recently. As digital environments, so as ecosystems, they have potential in terms of networked learning as they fulfill some roles such as mediating an environment for digital identity formation and providing social and emotional presence. Based on this phenomenon, the importance of identity formation as a sociological and psychological process was explained throughout this study. Following that, social networks as digital social ecosystems and learning environments in which self-actualization, self-presentation, and self-disclosure of the individuals were discussed and their necessity as well as their potential for social and emotional presence was explained to better understand social networks. Besides, social networks and “Facebook” as a case were examined. Within this perspective, the purpose of this study was to explore online social networks with an emphasis on learning; to put forward its educational premises; and to analyze digital identity formation, social presence, and emotional presence in social networks.     

Social Justice and Resilience for African American Male Counselor Educators: A Phenomenological Study

In this phenomenological study, the authors interviewed 4 African American male counselor educators about their social justice efforts. Resulting themes were lifelong commitment to social justice, reaction to resistance, professional and personal support, and the meaning of social justice work. Findings suggest that social justice work can increase professional resilience for African American male counselor educators.

Participatory learning culture and community formation in connectivist MOOCs

The purpose of this research is to better understand community formation in MOOCs through employing combined lenses of connectivism, rhizomatic learning, actor-network theory, community of practice, and community of inquiry. In a sequential explanatory mixed methodology design, social network analysis and nethnography were used to analyze and interpret data from a five-week, open and freely available MOOC, #humanMOOC, conducted in late 2015 and early 2016. The findings revealed that both intrinsic and extrinsic drives have unique roles in community formation process and support. These include respect and transparency in mutual communication, being socially visible and building a digital identity, seeing the relationships and patterns among the ideas, and being emotionally present and creating a welcoming, safe place are some effective internal drives, while opportunities to connect to personally meaningful sources or nodes, being able to wander among open ecologies, using nonhuman elements to facilitate learning, creating a safe base ground for initial activities, and creating community goods and well-designed learning spaces that meet diverse needs of the learners are some external drives.
