Using Psychological Characteristics of Situations for Social Situation Comprehension in Support Agents
Support agents that help users in their daily lives need to take into account
not only the user's characteristics, but also the social situation of the user.
Existing work on including social context uses some type of situation cue as an
input to information processing techniques in order to assess the expected
behavior of the user. However, research shows that it is important to also
determine the meaning of a situation, a step which we refer to as social
situation comprehension. We propose using psychological characteristics of
situations, which have been proposed in social science for ascribing meaning to
situations, as the basis for social situation comprehension. Using data from
user studies, we evaluate this proposal from two perspectives. First, from a
technical perspective, we show that psychological characteristics of situations
can be used as input to predict the priority of social situations, and that
psychological characteristics of situations can be predicted from the features
of a social situation. Second, we investigate the role of the comprehension
step in human-machine meaning making. We show that psychological
characteristics can be successfully used as a basis for explanations given to
users about the decisions of an agenda management personal assistant agent.Comment: 21 page
Pilot experiment exploring the priority of social situations
The research explores the priority of social situations. 17 TU Delft employees filled in an online survey. In the first part, they were asked to answer a set of questions about their relationship with 6 people from their lives. Afterwards, they were shown 20 meeting scenarios, each including one of those people, and they were asked what priority they would give to that scenario. Each row of the data represents a meeting instance and describes features about the relationship and about the meeting type, as well as the assigned priority
Mixed germ cell tumor of the pineal gland in a pediatric patient
Tumors of the pineal region are a rare clinical entity, comprising approximately 3%-8% of pediatric tumors. Based on their histopathological features, they are typically classified as pineal parenchymal tumors and germ cell tumors, with the latter being more prevalent. Clinical presentation is heterogeneous, with symptoms arising either due to tumor invasion or compression of adjacent neurovascular structures and increased intracranial pressure. Imaging studies are paramount in evaluating pineal region lesions and establishing an accurate diagnosis, with MRI representing the gold standard. Herein, we present the case of a 16-year-old boy presented with recurrent headaches. A head MRI revealed a pineal gland lesion. Histopathological examination confirmed the diagnosis, and the patient underwent a successful gross total resection (GTR) of the tumor. This case report seeks to draw attention to the elusive clinical presentation and management of this infrequently encountered tumor, as well as emphasize the importance of considering pineal gland tumors in the differential diagnosis of recurrent, chronic headaches in pediatric patients
Gorham-Stout disease, a diagnosis of exclusion
Gorham-Stout disease (GSD) also known as vanishing bone disease is an idiopathic and rare condition characterized by gross and progressive bone loss along with excessive growth of vascular and lymphatic tissue. Very little is known about the pathogenesis of GSD, which makes the diagnosis challenging and often diagnosed by elimination. We report a case of GSD in a 41-year-old male patient. He presented with bone pain and initial imaging showed widespread osteolytic lesions in the cervical and mid thoracic spine, ribs, sternum, clavicles, scapula, and humerus. Two percutaneous bone biopsies were performed, followed by an open spine biopsy of the lumber 2 spinous process for histological examination. Unfortunately, no diagnosis was reached. Although, he was treated symptomatically, he kept enduring pain and presented again after 7 months. His laboratory values were out of the normal range which prompted thorough investigations. New imaging and bone biopsy revealed multiple osteolytic lesions and vascular lesion with cavernous morphology respectively. GSD was diagnosed after ruling out a neoplastic process and confirming the cavernous morphology with immunohistochemical stain. He was treated symptomatically with immunomodulators, bisphosphonates, and supplements. Patient was counseled to see the specialist regularly. This case will help to increase familiarity and shed insights in the diagnosis of GSD
Septo-optic dysplasia in an infant
Septo-optic dysplasia (SOD) is a rare congenital disorder occurring in only 1 in 10,000 live births. Initially it was described in 1941 by Reeves and further discussed by the French-Swiss neurologist de Morsier (1956) as the disease further addressed his name. SOD is a combination of triads of hypoplasia of the optic nerve, agenesis of midline brain structures, and hypoplasia of the hypothalamic-pituitary axis. The pathophysiology of this rare congenital anomaly is yet to be understood, with some hypotheses in order to establish the diagnosis. The management modality depends on the presentation of the disease and requires a multidisciplinary approach. While most SOD patients present with visual, neurological, or endocrine abnormalities, in our case the patient was diagnosed incidentally while following up after an episode of acute respiratory distress syndrome and sepsis. We aim to highlight the aspects of clinical presentation in a patient with SOD and the importance of a multimodality follow-up approach
The 6th Albanian Congress of Trauma and Emergency Surgery
After a three-year quarantine from the deadliest global pandemic of the last century, ASTES is organizing to gather all health professionals in Tirana, The 6th Albanian Congress of Trauma and Emergency Surgery(ACTES 2022) on 11-12 November 2022, with the topic Trauma & Emergency Surgery and not only...with the aim of providing high quality, the best standards, and the best results, for our patients ...ACTES 2022 is the largest event that ASTES (Albanian Society for Trauma and Emergency Surgery) has organized so far with 230 presentations, and 67 foreign lecturers with enviable geography, making it the largest national and wider scientific event.The scientific program is as strong as ever, thanks to the inclusiveness, where all the participants with a mix of foreign and local lecturers, select the best of the moment in medical science, innovation, and observation.The scientific committee has selected all the presentations so that the participants of each medical discipline will have something to learn, discuss, debate, and agree with updated methods, techniques, and protocols.I hope you will join us on Friday morning, and continue the journey of our two-day event together
