用消費者行為改進銷售預測 / Improved sales forecasting with consumer behavior馬克斯, zur Muehlen, Maximilian Unknown Date (has links)
本篇目的---對於精實企業來說資訊預測的能力扮演舉足輕重的角色,如汽車製造商須要有可靠的資訊來完成各項重要的決策以保持企業競爭力,市場以及消費者的活動提供了新型態的資料可以透過現代科技來處理分,本篇論文希望從2008年至2016年整合的Google 搜尋趨勢資料來建構預測模型。
設計/方法論/方法---基於五階段消費者購買行為,此研究檢視整個過程中合適的Google關鍵字,並利用滯後變數模型和Google搜尋趨勢來驗證銷售和各種經濟變數之間的關係,預測的銷售會更進一步檢視其正確性。
結論與發現---用來檢視預測正確性的兩種最常見的方法指出Google搜尋趨勢可以作為有效的銷售預測依據,研究發現總體經濟變數和時間序列在預測上相較於Google搜尋趨勢在短期相對有效性小。
研究貢獻---僅有少許在汽車銷量預測上的研究將Google搜尋趨勢和合適的時間滯留列入考量,本篇研究提供消費者行為和銷售資料關係的新視角。 / Purpose – The role of forecasting in a lean enterprise is immense. It is crucial for car manufacturers to have reliable information about the future to make important decisions and stay competitive. Developing markets and consumers provide new types of data that demand modern approaches to be handled. This paper aims to create reliable forecasting models through integration of Google Trends data from 2008 to 2016.
Design/methodology/approach – Building on the 5-stage-model of consumer buying behavior, the study identifies suitable Google keywords for this process. Autoregressive distributed lag models are used to examine the relationship between sales and macro-economic variables as well as Google Trends. Predicted sales are used to test for accuracy.
Findings – Two most common evaluation measurements for forecasting accuracy suggest the use of Google Trends, as predictors for future sales, is outstanding. The finding concludes that macro-economic variables and seasonality are not as valuable as Google Trends in short-term, up to one year, forecasting.
Value – Only little research on car sales forecasting takes Google Trends and their appropriate time lags into account. This analysis provides new insights into the linkage of consumer behavior and sales data.

Exportní a importní funkce (empirická analýza na příkladě České republiky) / Export and Import functions (Empirical analysis on the example of the Czech Republic)Obešlo, František January 2014 (has links)
This work focuses on import and export of goods of the Czech Republic. The Czech Republic is very open country in European Union. Ratio of import and export of goods and services to GDP is above European Union average. The goal is to find explaining variables, which has an influence on import and export of goods and to create robust and economically interpretable models. Models are created by cointegration analysis. The advantage of cointegration analysis and error correction models is avoiding spurious regression and differentiation of short-term and long-term relations. There will be used two attitudes for creation of models: with help of ADL models and Johansen method, which serve to comparison of results. There is a space for test of influence of exchange rate shocks on import and export of goods in the end.

Djurterapins påverkan på äldre personer med demenssjukdom : En systematisk litteraturstudie / Impact of Animal-Assisted therapy on older people with dementia : A systematic literature studyÖdéen, Mikaela, Gustafsson, Christin January 2022 (has links)
Bakgrund: Vid demenssjukdom medföljer ofta symtom som försämrat minne och kognitiva funktioner samt olika beteendemässiga och psykiska problem (BPSD). Dessa symtom kan påverka de drabbade personernas i form av försämrad livskvalité och svårigheter att utföra aktiviteter i dagliga livet (ADL). Genom olika strategier, anpassa miljön och genom att interagera djurterapi med arbetsterapi kan arbetsterapeuter hjälpa och stötta personer med demenssjukdom. Syfte: Syftet var att beskriva hur djurterapi påverkar äldre personer med demenssjukdom avseende deras ADL, livskvalité och BPSD. Metod: Systematisk litteraturstudie. Där nio artiklar inkluderades från databaserna psycINFO och Scopus. Artiklarnas innehåll kvalitetsgranskades genom dataextraktion och McMasters mall för kvantitativa studier. Bedömning av tillförlitligheten på utfallsmåtten granskades enligt GRADE evidensgradering. Resultat: Resultatet visade på indikationer för att djurterapi kan förbättra ADL, livskvalité och BPSD för personer med demenssjukdom, flest signifikanta resultat uppmättes inom utfallsmåttet BPSD. Evidensgradering av utfallsmåtten visade på otillräckligt evidensvärde för ADL och BPSD-depression och begränsat evidensvärde för livskvalité och BPSD-aggression. Slutsats: Resultatet i föreliggande systematiska litteraturstudie indikerar att djurterapi kan förbättra ADL, livskvalité och BPSD för personer med demenssjukdom, men evidensen för resultatet är låg. / Background: Dementia is often accompanied by symptoms such as impaired memory, cognitive functions, and various behavioral and psychological symptoms (BPSD). These symptoms can afflict the persons in the form of impaired quality of life (QOL) and difficulties in performing activities of daily living (ADL). Through strategies, adjust the environment and by interacting animal therapy with occupational therapy, occupational therapists can help and support people with dementia. Aim: To describe how animal therapy affects older people with dementia regarding their ADL, QOL and BPSD. Method: Systematic literature study. Nine articles were included from the databases PsycINFO and Scopus. The content was quality reviewed through data extraction and McMaster's template for quantitative studies. Assessment of the reliability of the outcome was examined according to the GRADE evidence rating. Results: The results showed indications that animal therapy can improve ADL, QOL and BPSD for people with dementia, the most significant results were measured within BPSD. The evidence grading showed insufficient evidence value for ADL and BPSD-depression and limited evidence value for the QOL and BPSD-aggression. Conclusion: The results of this systematic literature study indicate that animal therapy can improve ADL, QOL and BPSD for people with dementia, but the evidence for the results is low

Hemtjänstpersonals erfarenheter av arbetsterapeuters handledning i äldreomsorgGanebo, Catharina January 2010 (has links)
<p><strong></strong><strong></strong><strong></strong>Syftet med studien var att beskriva erfarenheter som hemtjänstpersonal har av handledning. Metoden var kvalitativ, med enskilda, öppna intervjuer. Sju personer som arbetar i kommunal hemtjänst intervjuades. Intervjumaterialet analyserades med kvalitativ innehållsanalys. Resultatet visar att samarbete mellan arbetsterapeut och hemtjänstpersonal är en förutsättning för att arbetsterapeutens insatser ska komma brukaren till nytta. Resultaten visar vidare att hjälpinsatsens utformning påverkas av om arbetsterapeuten gjort en tidig rehabiliteringsinsats. Det är främst genom dialog med arbetsterapeuten och praktisk handledning i vardagsarbetet som hemtjänstpersonalen får tillgång till den kunskap och information som handledningen har för avsikt att förmedla. Deltagarna förordade praktisk handledning. Den upplevdes ge kunskaper som de direkt kunde tillämpa i sitt arbete, samt skapa förutsättningar för ett enhetligt arbetssätt inom hemtjänstgruppen. Studien synliggör behov av rutiner kring överrapportering. Arbetsterapeuten bör prioritera att snabbt lämna ut information gällande ADL-förmågor. Enligt erfarenheterna var handledning väsentlig kring varje enskild brukare och behöver finnas att tillgå när den efterfrågas av hemtjänstpersonalen. För att arbetsterapeutens handledning skall vara till verklig nytta för brukaren krävs ett gott samarbete mellan samtliga yrkeskategorier i teamet.</p>

Previous issue date: 2014-03-26 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / The increase in ultraviolet radiation (UV) at surface, the high incidence of non-melanoma skin cancer (NMSC) in coast of Northeast of Brazil (NEB) and reduction of total ozone were the motivation for the present study. The overall objective was to identify and understand the variability of UV or Index Ultraviolet Radiation (UV Index) in the capitals of the east coast of the NEB and adjust stochastic models to time series of UV index aiming make predictions (interpolations) and forecasts / projections (extrapolations) followed by trend analysis. The methodology consisted of applying multivariate analysis (principal component analysis and cluster analysis), Predictive Mean Matching method for filling gaps in the data, autoregressive distributed lag (ADL) and Mann-Kendal. The modeling via the ADL consisted of parameter estimation, diagnostics, residuals analysis and evaluation of the quality of the predictions and forecasts via mean squared error and Pearson correlation coefficient. The research results indicated that the annual variability of UV in the capital of Rio Grande do Norte (Natal) has a feature in the months of September and October that consisting of a stabilization / reduction of UV index because of the greater annual concentration total ozone. The increased amount of aerosol during this period contributes in lesser intensity for this event. The increased amount of aerosol during this period contributes in lesser intensity for this event. The application of cluster analysis on the east coast of the NEB showed that this event also occurs in the capitals of Paraiba (Jo?o Pessoa) and Pernambuco (Recife). Extreme events of UV in NEB were analyzed from the city of Natal and were associated with absence of cloud cover and levels below the annual average of total ozone and did not occurring in the entire region because of the uneven spatial distribution of these variables. The ADL (4, 1) model, adjusted with data of the UV index and total ozone to period 2001-2012 made a the projection / extrapolation for the next 30 years (2013-2043) indicating in end of that period an increase to the UV index of one unit (approximately), case total ozone maintain the downward trend observed in study period / A eleva??o da radia??o ultravioleta (UV), a alta incid?ncia de c?ncer de pele n?o melanoma (CPNM) no Nordeste do Brasil (NEB) e a redu??o da coluna total de oz?nio foram os motivadores do presente estudo. O objetivo desta investiga??o ? identificar e compreender a variabilidade da UV e do ?ndice de Radia??o Ultravioleta (?ndice UV) nas capitais da costa leste do NEB e ajustar modelos estoc?sticos ?s s?ries temporais do ?ndice UV visando realizar predi??es (interpola??es) e previs?es/proje??es (extrapola??es) seguido de an?lise de tend?ncia. A metodologia consistiu da aplica??o da an?lise multivariada (an?lise de componentes principais e an?lise de agrupamentos), m?todo Predictive Mean Matching (PMM) para preenchimento de falhas nos dados, modelo autoregressivo de defasagens distribu?das ou Autoregressive Distributed Lag (ADL) e teste Mann-Kendal. A modelagem via ADL ocorreu atrav?s da estima??o de par?metros, diagn?stico, an?lise de res?duos e avalia??o da qualidade das predi??es/previs?es via erro quadr?tico m?dio e coeficiente de correla??o de Pearson. Os resultados da investiga??o indicaram que a variabilidade anual da UV na capital do Rio Grande do Norte (Natal) possui uma caracter?stica nos meses de setembro e outubro que consiste em uma estabiliza??o/redu??o do ?ndice UV em raz?o da maior concentra??o anual de oz?nio total. A maior quantidade de aeross?is neste per?odo contribui em menor intensidade para este evento. A aplica??o da an?lise de agrupamento (cluster) na costa leste do NEB mostrou que este evento tamb?m ocorre nas capitais da Para?ba (Jo?o Pessoa) e Pernambuco (Recife). Os eventos extremos da UV do NEB foram analisados a partir da cidade de Natal e estavam associados ? falta de cobertura de nuvens e n?veis abaixo da m?dia anual de oz?nio total e n?o ocorriam na totalidade da regi?o em fun??o da distribui??o espacial desigual dessas vari?veis. O modelo ADL (4, 1), ajustado com dados do ?ndice UV e oz?nio total para o per?odo de 2001 a 2012, realizou a proje??o/extrapola??o para os pr?ximos 30 anos (2013-2043) indicando ao fim deste per?odo eleva??o de aproximadamente uma unidade do ?ndice UV, caso o oz?nio total mantenha a tend?ncia de queda verificada no per?odo de estudo

Kvinnors upplevelser av sin sexualitet efter bekräftad bröstcancerdiagnos sett ur ett aktivitetsperspektiv / Women’s experiences of their sexuality after confirmed breast cancer diagnosis seen from an activity perspectiveMelin, Linda, Thörn, Hanna January 2022 (has links)
Introduktion Det finns en kunskapslucka kring kvinnors upplevelser av sin sexualitet efter bekräftad bröstcancerdiagnos. Sexuell hälsa är ett relevant ämne för arbetsterapeuter som kräver vidare forskning för att kunna erbjuda dessa kvinnor individanpassat stöd inom ramarna för sexuell hälsa och arbetsterapi. Syftet med studien var att identifiera kvinnors upplevelser kring sin sexualitet efter bekräftad bröstcancerdiagnos. Metoden som användes var en kvalitativ intervjustudie med semistrukturerade intervjufrågor. Informanterna rekryterades genom ett bekvämlighetsurval. Tio kvinnor med bekräftad bröstcancer intervjuades, materialet analyserades enligt en kvalitativ innehållsanalys. Resultat Innehållsanalysen resulterade i fyra teman; Sexualiteten påverkas av en förändrad kropp och självbild, Ingen vill ta ansvar för sexualiteten, Sexualiteten bortprioriterades när cancern kastade omkull livet och Det finns ett behov av att prata om sexualitet. Slutsatsen av studien är att kvinnorna inte tänkte på sin sexualitet direkt efter bröstcancerbeskedet utan först när behandlingarna påbörjats. Kvinnorna upplevde att vården brast i frågor kring sexualitet och återgång till betydelsefulla aktiviteter. / Introduction There is a knowledge gap around women’s experiences of their sexuality after a confirmed breast cancer diagnosis. Sexual health is a relevant topic for occupational therapists that requires further research to offer these women individualized support within the frames of sexual health and occupational therapy. The purpose of this study was to identify women’s experiences about their sexuality after a confirmed breast cancer diagnosis. The chosen method was a qualitative interview study with semi-structured interview questions. The informants were recruited through a convenience sampling. Ten women with confirmed breast cancer were interviewed, the data were analyzed according to a qualitative content analysis. Results The content analysis resulted in four themes; The sexuality is affected by a changed body and body image, No one wants to take responsibility for sexuality, Sexuality was de-prioritized when cancer overthrew life and There is a need to talk about sexuality. The conclusion of the study is that women did not think of their sexuality when receiving a breast cancer diagnosis. However, they did think about it when starting the breast cancer treatments. The women experienced deficiencies in healthcare related to sexuality and return to meaningful occupations.

P.E.G.A.S : Powered Exoskeleton Grip Amplifying SystemDyberg, Malin, Troillet Ahlbäck, Elvira January 2021 (has links)
In this bachelor’s thesis, the development and construction of a soft exoskeleton for a human hand is described.The purpose of the project includes evaluating what type of exoskeleton that is most suitable for aiding the user inactivities of daily living and how this exoskeleton can be constructed in order to increase grip strength in the human hand. In addition, the prototype should be portable and not inflict any harm on the user. The necessary theoretical research is thoroughly conducted followed by the construction of the final prototype. The purpose of the project is achieved, resulting in a flexible, portable and safe exoskeleton which with satisfaction can aid the user in its activities of daily living. However, this prototype is limited to exclusively include the thumb and index finger, and in further work the prototype can be developed to include all five fingers of the human hand. / I detta kandidatexamensarbete behandlas utvecklingen och konstruktionen av ett mjukt exoskelett för den mänskliga handen. Syftet med projektet är att undersöka vilken typ av exoskelett som passar bäst för att hjälpa användaren med aktiviteter i det dagliga livet, samt hur detta exoskelett kan konstrueras för att förstärka greppet i handen. Prototypen ska även vara bärbar och inte skada användaren. Den nödvändiga teorin presenteras, följt av konstruktionen av den slutgiltiga prototypen. Syftet med projektet uppfylls och resulterar i ett flexibelt, portabelt och säkert exoskelett som kan hjälpa användaren med aktiviteter i det dagligalivet. Dock är denna prototyp begränsad till att endast inkludera styrning av tummen och pekfingret, och prototypenkan således i framtida arbeten utvecklas till att inkludera samtliga fem fingrar på den mänskliga handen.

Ergoterapie v rámci interprofesní spolupráce v komunitní rehabilitaci osob po poškození mozku / Occupational therapy within interprofessional collaboration in community - based rehabilitation for people after brain damagePtaková, Silvie January 2019 (has links)
As a result of rapid development in Emergency Medicine and Intensive Care the patients with brain damage have better chances of surviving than they had in the past. However the survivors need to deal with severe loss of function and consequences resulting from that. An excellent primary care for patients who suffer from strok is provided in Czech Republic, the rehabilitation on the other hand is insufficient. The main problem is an absence of continuity of care which leads to aneffective outcomes and increase of total costs of treatment The purpose of this diploma theses was to evaluate the possibilities of occupational therapist of interprofessional collaboration in community based rehabilitation - in client's home environment. There are several categories of brain damage including acquired brain injury, genetic brain disorders and brain damage acquired during labor. The goal was to detect basic deficient fields. Results of this thesis based on knowledge from foreign literature as well as own experiencis in the team. Results might be used as basis for designed guidelines to improve situation. One client with degenerative brain disorder and five with acquired brain injury which live in home environment were selected. Three months long therapy was provided to them, occupational therapist as case...

Objective physical measures and their association with subjective functional limitations in a representative study population of older ThaisPrasitsiriphon, Orawan, Weber, Daniela January 2019 (has links) (PDF)
In this study, we analyzed elderly people in Thailand to identify the validity of suggested cutoff points of physical measures, handgrip strength, usual walking speed, and a composite score of both measures to predict functional limitations. Moreover, we examined whether these physical performance measures are accurate indicators of the investigated health outcomes.
Methods: Using Receiver Operating Characteristics (ROC) analysis, we investigated a sample of 8272 respondents aged 60 to 79 years. All data were based on the 2009 National Health Examination Survey (NHES IV) of Thailand.
Results: For males aged 60 to 69 years, handgrip strength was used as an indicator of functional limitations. The cutoff point for disabilities in the activities of daily living (ADLs) was 29.5 kg, while in other limitations it ranged from 28.7 to 31.3 kg. In contrast, usual walking speed was able to indicate ADL disabilities at 0.7 m per second (m/s). As one might expect, the cutoff points for males aged 70 to 79 years were lower than for males in the 60 to 69 age group. For females, handgrip strength was able to indicate ADL disabilities at 16.5 kg for both the 60 to 69, and 70 to 79 age groups. Likewise, walking speed was indicative of ADL disabilities at 0.6 m/s for both age groups. Interestingly, the composite measure increases the ability to detect ADL disabilities in the younger group but not in the older group. The area under the curve (AUC) of cutoffs measuring the detection power of a diagnostic test was varied, ranging from 0.535 to 0.7386.
Conclusions: The cutoff points of three measures varied according to sex and type of functional limitations. Our findings also showed that physical performance measures were useful for identifying people with an increased risk of functional limitations, particularly for ADL disabilities. However, although the AUC of the cutoffs of other functional limitations were relatively low, they should be considered with caution.
