Learning in multiple communities from the perspective of knowledge capital

In a learning system, multiple communities represent a networked structure of learning experiences. Individuals belong to multiple communities connected though complex relationships consisting of people, resources, rituals, and ties. Learning occurs as individuals traverse this network from one community to the next. This paper explores the question of how learning occurs in compound communities from the perspective of knowledge capital, that is, the communities’ collective knowledge, skill, and perspective, as well as relationships and connections among members. Through interviews conducted with postgraduate students belonging to multiple communities, we identified issues related to conflict between communities, closed-congregation communities, privacy, and reputation. The results have implications concerning social and structural aspects of learning and instructional design in multiple communities

Evaluation of the relationship between the topographical anatomy in the axillary region of the brachial plexus and the body mass index

WOS: 000439345200023PubMed ID: 28871408To investigate the topographic anatomy of the median, musculocutaneous, radial and ulnar nerves with respect to the axillary artery and to seek whether these configurations are associated with baseline descriptive data including age, gender, and body-mass index. This cross-sectional trial was carried out on 199 patients (85 women, 114 men; average age: 46.78 +/- 15.45 years) in the department of anaesthesiology and reanimation of a tertiary care center. Topographic anatomy of the median, musculocutaneous, radial and ulnar nerves was assessed with ultrasonography. Localization of these nerves with respect to the axillary artery was marked on the map demonstrating 16 zones around the axillary artery. Frequencies of localizations of every nerve in these zones were recorded, and the correlation of these locations with descriptive data including age, gender and BMI was investigated. There was no difference between women and men for the distribution of the median (p = 0.74), ulnar (p = 0.35) and radial (p = 0.64) nerves. However, the musculocutaneous nerve was more commonly located in Zone A13 in men compared to women (p = 0.02). The localization of the median (p = 0.85), ulnar (p = 0.27) and radial (p = 0.88) nerves did not differ remarkably between patients with BMI < 25 kg/m(2) and patients with BMI 25 kg/m(2). Notably, the musculocutaneous nerve was more often determined in Zone A10 in cases with BMI 25 kg/m(2) (p = 0.001). Our results imply that the alignment of the musculocutaneous nerve may vary in men and overweight people. This fact must be considered by the anaesthetist before planning the axillary block of brachial plexus. All these informations may enlighten the planning stages of the brachial plexus blockade

Examining Value Change in MOOCs in the Scope of Connectivism and Open Educational Resources Movement

Massive Open Online Courses (MOOCs) came to prominence with Open Educational Resources Movement (OERM). It was based upon the idea of libre in removal of some permission barriers and gratis in removing the price barrier (Suber, 2008) in learning resources. In line with the theoretical underpinnings of OERM, MOOCs embody primary characteristics of connectivist pedagogy which are autonomy, diversity, openness, and community participation. However, in time, moving away from its original philosophical and pedagogical values, new variations of MOOCs have emerged and new MOOCs have become more market oriented and are aligned with instructivist, cognitive, and behaviourist pedagogy. In an attempt to empirically examine the change in underlying values of the MOOCs, a survey method was employed by using a Connectivist Learning Environment Assessment Tool which was developed in the scope of this research. The tool could be useful for formulating and justifying a conceptual framework that enables us to reify the connectivist pedagogy and assess connectivist underpinnings of a learning environment including MOOCs. This research aims to contribute to MOOC studies against the background of previous knowledge from the Open Education and Connectivist fields

Bir eğitim-araştırma hastanesinde istenen psikiyatri konsültasyonlarının değerlendirilmesi ve psikiyatrik hastalıkların doğru tanınma oranları

Objective: In this study, it was aimed to evaluate the psychiatric consultations required for inpatients in an education-research hospital and to examine the correct recognition rates of psychiatric diseases by other physicians. Method: Psychiatric consultations for patients who were hospitalized at Ankara Numune Training and Research Hospital except psychiatry and emergency department had been retrospectively screened between 01/04/2016 - 01/10/2016. Results: During this period, 27457 patients were hospitalized in Ankara Numune Hospital apart from the emergency department and psychiatric services, and a total of 544 (1.9%) psychiatric consultations were requested. Psychiatric consultations were most frequently requested with the reason of agitation (17.5%); 16.9% did not specify any reason. Anxiety (8.3%), drug treatment regulation (6.1%), delirium (5.5%), sleep problems(5.3%) and pre-transplant evaluation (4.4%) are other common causes of consultation. The highest rate of psychiatric consultation was in the bone marrow transplant unit (21.0%) followed by infectious diseases (9.6%), intensive care (9.5%) and physical medicine and rehabilitation (9.0%). There was no psychiatric disease in 29.4% of the requested consultations. 149 patients (27.4%), were diagnosed with anxiety disorder,70 patients (12.9%) with delirium, 37 patients (6.8%) with depression, 22 patients (3.7%) with alcohol / substance use disorder, 20 (3.7%) patients with psychotic disorder, 15 patients (2.8%) with trauma related disorders, and 2 patients (0.4%) were diagnosed with somatization disorder. Delirium had the highest rate of recognition by primary medical care providers (89.5%), followed by anxiety disorders (55.6) and alcohol-substance use disorders (53.3%). Discussion: In this study, psychiatric consultation rates were found to be low, psychotic disorders and somatization disorders are not well recognized even though delirium is well known by primary medical care providers

Axis I dissociative disorder comorbidity in borderline personality disorder and reports of childhood trauma

Objective: The purpose of this study was to examine the dissociative disorder comorbidity of borderline personality disorder and its relation to childhood trauma reports in a nonclinical population

The beneficial effects of ozone therapy in acetaminophen-induced hepatotoxicity in mice

Impacts of Ozone Treatment and Its Relationship with IGF-1 Levels After Injury of Soft Tissue: An Experimental Study in Rats Model

To investigate the effects of ozone treatment on soft tissue injury and to observe whether there is an alteration in serum IGF-1 levels after ozone treatment in an experimental rat model. Twenty-four adult Wistar albino 240-350 g male rats were randomly allocated into two groups. A standardized, experimental soft tissue injury was created on left hind limbs of animals. Group 1 underwent daily ozone treatment intraperitoneally (20 mu g/mL), while Group 2 received only nutrition and routine care. All rats were evaluated regarding body weight and sensory and motor function on 5th and 15th days after experimental trauma. Blood samples were drawn from intracardiac in group 1 and group 2 serum levels of IGF-1 level were measured at the day of 15th. During follow-up period after formation of soft tissue injury, three rats in Group 2 had cutaneous infection that responded well to topical tetracycline treatment. Two groups displayed similar results regarding sensory and motor functions on 5th and 15th days. Serum IGF-1 level in Group 1 was significantly higher than that of Group 1 (P=0.03). Serum IGF-1 level was correlated with motor function on day 15 in Group 1 (P=0.04) and with motor function on day 5 in Group 2 (P=0.011). Ozone treatment may have favorable impacts on healing and regeneration process in connective and muscle tissues and these beneficial effects may be mediated by IGF-1. Further research is warranted to elucidate the role of IGF-1 in repair process and to provide additional new insights to the treatment strategies
