Telewrite: A New Telehealth-Based Assessment to Evaluate the Handwriting Skills of Children in First Through Third Grade

Guzman, Julia M. January 2021 (has links)
Telehealth is needed urgently nationwide, given the COVID-19 pandemic. It isespecially urgent in rural and less populated areas where healthcare access is limited. Currently, because there are no pediatric handwriting assessments validated for telehealth use, the TeleWrite assessment would fill an unmet service need and expand the use of telehealth-based occupational therapy (OT) assessment in pediatric practice. This dissertation explored the preliminary psychometric properties of TeleWrite, a handwriting assessment tool designed to measure the legibility and fluency of handwriting for children in first through third grade administered via telehealth. A series of studies were completed to determine initial interrater reliability, content validity, and clinical utility using classical test theory. The Rasch model of measurement was used to determine the preliminary psychometric properties of TeleWrite using Winsteps® (v. 4.7.0). The quantitative Rasch analysis of TeleWrite included administration of the tool to 148 children from first to third grade. This study tested the initial construct validity (internal validity) and test reliability of TeleWrite using the Rasch model of measurement. The Partial Credit Model (PCM) was used for rating scale analysis because TeleWrite is composed of three distinct scales (handwriting rate, accuracy, and fluency) that differs per task (near point or far point) and per grade level. The Rasch analysis showed a generally good fit with the Rasch unidimensional model, indicating strong construct and internal validity and moderate ability to separate abilities of students reliably in terms of handwriting skills. However, following the Rasch model, a larger sample is necessary to obtain improved calibration, reliability, and validity measures. This study and supported by the literature described the need for a new handwriting evaluation tool validated for telehealth use. The findings of the current research contribute to the literature and OT practice as the first handwriting assessment specifically designed and validated for telehealth use that assesses all pertinent variables of handwriting associated with handwriting difficulties.

Tweeting in Times of Crisis: Shifting Personal Value Priorities in Corporate Communications and Impact on Consumer Engagement

Amozegar, Mahdiyeh 16 July 2021 (has links)
Branding in the age of social media is thriving as companies continue to pour resources into digital campaigns in the hope of engaging their customers. The onset of the COVID- 19 pandemic boosted the importance of digital communication channels as physical distancing and lockdown measures disrupted business-as-usual and limited in-person interactions between firms and their customers. By implication, the global crisis pressed companies to deliver brand messages via online content to sustain or build customer relationships. This research focuses first on the branded content of corporate communications during the pandemic, focusing specifically on whether firms used the opportunity to showcase shared personal values. Second, we examine whether using value words in social media messages impacts customer engagement with these messages. To address these related questions, we collected Twitter data from Fortune 500 firms posted between January 2020 until the end of August 2020, attending to 56,770 firm- initiated tweets (we excluded firm responses to customer messages). The first study examines the personal values expressed in the messages using the Personal Values Dictionary, based on Shalom Schwartz’s original ten-value typology. We argue that the unprompted expression of values in a text is a behavioural indicator of personal value priorities. The findings compare firms’ shifting value priorities over time and association with key events, namely the global pandemic declaration (March 11, 2020) and ensuing lockdowns and George Floyd’s murder (May 25, 2020), and BLM protests. We find that, indeed, companies did shift their value priorities. The second study assesses consumer response to the values companies put forth in their tweets, focusing on social media indicators of consumer engagement (CE), including the number of likes, retweets, replies, and CE correlation with the values promoted in the tweets. We observe a pre- post-crisis shift in CE with value-laden messages. Our findings provide managerial insights that can guide marketers to manage their social media content more efficiently and better align their marketing and branding efforts with customers' values in times of crisis.

Den paradoxala närvaron för ledare på distans : En kvalitativ studie om coronapandemins påverkan på bankchefers ledarskap och krishantering

Anklev, Sophie, Axelsson, Madeleine, Hedvall, Lovisa January 2021 (has links)
Syfte: Syftet med den här studien är att undersöka och få en ökad förståelse för hur bankchefer har förändrat och anpassat sitt ledarskap och sin krishantering under covid-19. Vi vill därmed bringa klarhet kring vad bankchefer upplever är viktigt i deras krishantering och ledarskap för att fortsätta driva verksamheten på lämpligaste sätt till följd av coronapandemin. Metod: Studiens metodval har varit kvalitativ metod, där vi har tillämpat en abduktiv forskningsansats. Med hjälp av teori och datainsamling har vi haft möjlighet att göra en hermeneutisk tolkning för att uppnå en förståelse och ur detta sedan dra adekvata slutsatser.  Slutsats: Studiens slutsats är att olika kriser är unika, där coronakrisen inte är ett undantag. Ur empiri och analys kunde vi utläsa särskilda ledaregenskaper som är viktiga för den här typen av kris som covid-19 är. I studien fann vi också att krishantering är en väsentlig del i ledarskapet och för bankkontorens funktionalitet under krisen. Ur vår teoretiska referensram kunde vi härleda ett antal gemensamma nyckelegenskaper som ledare bör tillämpa i sitt ledarskap, där exempelvis att vara kommunikativ, närvarande och lyhörd är viktigt.

"Ljudet är kasst" : En studie om gymnasielärares uppfattning av omställningen till distansundervisning år 2020 / "The sound is bad" : A studie of upper secondary school teachers´perceptions of the transition to distance education year 2020

Besic, Amina January 2021 (has links)
This essay is an analysis of a qualitative study made on 11 music teachers' view on distance learning during Covid-19. The purpose of this essay is, through a phenomenographic analysis, to see how music teachers who are working at the upper secondary school view distance learning and how they have worked with it since the spring of 2020.  The findings of this essay show that the delay and sound quality experienced during distance learning are the biggest issues according to the teachers. The findings also show that the students' motivation and grades have been affected negatively due to distance learning. The teachers' health has also been affected in such ways that their moral of work has been decreasing and the mental health for some has declined.

Learning COVID-19 network from literature databases using core decomposition

Guo, Yang 22 July 2021 (has links)
The SARS-CoV-2 coronavirus is responsible for millions of deaths around the world. To help contribute to the understanding of crucial knowledge and to further generate new hypotheses relevant to SARS-CoV-2 and human protein interactions, we make use of the information abundant Biomine probabilistic database and extend the experimentally identified SARS-CoV-2-human protein-protein interaction (PPI) network in silico. We generate an extended network by integrating information from the Biomine database and the PPI network. To generate novel hypotheses, we focus on the high-connectivity sub-communities that overlap most with the PPI network in the extended network. Therefore, we propose a new data analysis pipeline that can efficiently compute core decomposition on the extended network and identify dense subgraphs. We then evaluate the identified dense subgraph and the generated hypotheses in three contexts: literature validation for uncovered virus targeting genes and proteins, gene function enrichment analysis on subgraphs, and literature support on drug repurposing for identified tissues and diseases related to COVID-19. The majority types of the generated hypotheses are proteins with their encoding genes and we rank them by sorting their connections to known PPI network nodes. In addition, we compile a comprehensive list of novel genes, and proteins potentially related to COVID-19, as well as novel diseases which might be comorbidities. Together with the generated hypotheses, our results provide novel knowledge relevant to COVID-19 for further validation. / Graduate

Matic, Gabrijella, Al Kes Youssef, Stephan January 2021 (has links)
Title: Virtual work environment and its impact on employee motivation and performance. Keywords: virtual workplace, motivation, performance, covid-19 Research question: How is employees' motivation and performance affected in a virtual work environment? Purpose: The purpose of this study is to investigate how the individual's motivation and performance are affected by a virtual work environment during the current covid-19 pandemic from an employee perspective. Method: Case study methodology with semi-structured interviews with respondents from five different organizations and a systematic literature study (SLR). Conclusion: It is suggested that the virtual work environment entails an increased workload, which entails a negative impact on the employee’s motivation and performance. Furthermore, it is suggested that a combination of physical and virtual work environment is essential to achieve increased motivation and performance among the employees. Finally, it is suggested that a combination of both monetary and non-monetary rewards is considered essential to achieve increased motivation and performance among the employees. / Titel: Virtuell arbetsmiljö och dess påverkan på medarbetares motivation och prestation. Nyckelord: virtuell arbetsmiljö, motivation, prestation, covid-19 Frågeställning: Hur påverkas medarbetarnas motivation och prestation inom en virtuell arbetsmiljö? Syfte: Syftet med denna studie är att undersöka hur individens motivation och prestation påverkas av en virtuell arbetsmiljö under den rådande covid-19 pandemin utifrån ett medarbetarperspektiv.  Metod: Fallstudiemetodik med semi-strukturerade intervjuer med respondenter från fem olika organisationer samt en systematisk litteraturstudie (SLR).  Slutsats: Det antyds att den virtuella arbetsmiljön medför ökad arbetsbelastning vilket medför negativ påverkan på medarbetarens motivation och prestation. Vidare antyds det att en kombination mellan en fysisk och virtuell arbetsmiljö är väsentlig för att uppnå ökad motivation och prestation hos medarbetaren. Slutligen antyds att en kombination av dels monetära samt icke-monetära belöningar anses väsentliga för att uppnå ökad motivation och prestation hos medarbetaren.

Det ofrivilliga distansarbetet : En kvalitativ studie om psykosocial arbetsmiljö under covid-19

Dannapfel, Saga, Hafvenstein, Erica January 2021 (has links)
År 2020 drabbades Sverige av covid-pandemin och svenska Folkhälsomyndigheten går ut med olika rekommendationer och restriktioner för att hålla smittspridningen nere. En av restriktionerna var att distansarbete skulle införas på de arbetsplatser där det finns möjlighet till det. Distansarbete i sig är ingen ny företeelse men det som skiljer distansarbete under pandemin är att fler rekommenderas att enbart arbeta hemifrån under lång tid. Således har distansarbete ökats markant vilket medfört konsekvenser för hur vi interagerar på arbetet och arbetsmiljön. I och med dessa förändringar var det intressant att undersöka hur de nya förutsättningarna för arbetslivet påverkar individer och vilka konsekvenser det kan ha på den psykosociala arbetsmiljön. Detta har vi undersökt med sju kvalitativa intervjuer med tjänstemän inom Region Östergötland som övergått till att arbeta i princip enbart på distans under 2020-21. För att analysera och tolka resultatet har tidigare forskning kring distansarbete, psykosocial arbetsmiljö och balansteorin använts. Balansteorin handlar om att väga upp negativa arbetsförhållanden med positiva för att skapa en jämn balans. Resultatet visar att respondenterna inte upplevde att arbetet på kontoret och distansarbetet skiljer sig åt avsevärt. Digitala verktyg hjälper till att behålla den sociala kontakten med kollegor. I studien framkom att respondenterna upplevde fler avbrott i arbetet på kontoret och flera nämner att det varit effektivare i sitt arbete under distansarbete. Flera berättade även att det blivit mindre stressande att hantera balansen mellan arbete och hushållssysslor. Utifrån ovan upplevs distansarbete ha en rad olika fördelar och samtliga respondenterna vill i framtiden kunna kombinera dessa arbetssätt för att på kontoret vara social och kreativ men inte förlora den effektivitet och fokus som upplevs när de arbetar hemifrån.

Regeringens roll i en pandemi : En fallstudie om den peruanska regeringens styrningsroll under COVID-19 pandemin och dess offentliga implementering

Navarro Rojas, Mariana January 2021 (has links)
The aim of this essay is to study in what way the Peruvian government acted to contain the spread of the new Covid-19 virus. The essay has its roots in two policy documents which the government made based on what they believed were the best ways to contain the virus. Because of this the questions have been established on these two specific policy documents and its implementation on the society. The questions are therefore: what type of measures have the government taken? what type of governance has been used? And how are the measures going to be implemented and to what extent of possibility’s are there to implement. The method is a qualitative case study with two perspectives: governance and implementation. The results show that in practice the policy documents have been conducted from a top-down perspective where the government has been the face outwards the population, but different authorities have had tasks presented by the government.
