Developing and Establishing the Reliability and Validity of the East Asian Student Stress Inventory (EASSI)

Ding, Jiansan 05 1900 (has links)
The primary purpose of this study was to develop and establish the reliability and validity of the East Asian Student Stress Inventory. Data was obtained from 235 East Asian students at the University of North Texas during the fall semester of 1992. The procedures used were a two-week interval test-retest for reliability, experts' assessment of test items for face validity, a factor analysis, a one-way analysis of variance (ANOVA), and Pearson's product-moment correlation coefficient for construct validity. Significance was set at the .05 level. The EASSI was identified as having moderately high reliability. High test anxiety, physiological symptoms, social support, financial difficulty, and culture shock were found to be constructs of the EASSI. Majority of independent variables in this study effectively identified stressors and stresses among East Asian students.

Distractibility, Impulsivity, and Hyperactivity Measured by the Kaufman Assessment Battery for Children and Personality Inventory for Children

Alcantara, Helene Deborah-Lynne 05 1900 (has links)
Basic criteria for determination of Attention Deficit Hyperactivity Disorder (ADHD) include hyperactivity, impulsivity, and distractibility. Four scales of the Personality Inventory for Children have been found to be useful in the diagnosis of ADHD. Impulsivity and distractibility can affect scores on the Hand Movements, Number Recall, Word Order, Spatial Memory, Arithmetic, Riddles, and Matrix Analogies subtests of the Kaufman Assessment Battery for Children. Subjects were 100 children, aged six through 13 who were referred for psychological assessment. The purpose of this study was to determine if there was a correlation between scores on the four scales of the PIC and the designated subtest scores on the KABC. Four correlations were significant, but of low magnitude.

No. of bitstreams: 1 HanniaRRPR_DISSERT.pdf: 2137181 bytes, checksum: ae4af965fe56dad2f3f8c2d06548931d (MD5) Previous issue date: 2011-05-23 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Millon describes the normal personality by means of adaptation styles that are effective in normal environments and personality disorders such as unadapted operating styles. To operacionalize his theoretical model, Millon has built several instruments, including the Millon Clinical Multiaxial Inventory III (MCMI-III), wich consists of a self report inventory composed by 175 true or false response items, containing four verification scales, and others scales wich evaluates 14 personality patterns and 10 clinical syndromes. The Substance Dependence scale (T) is placed along with Clinical Syndromes scales. This research is justified by the lack of a Brazilian instrument to assess personality psychopathological aspects, and aims to translate and semantically adapt the MCMI-III to the Brazilian context, checking validity elements of the Substance Dependence scale, and developing a computer application for assisting the evaluation of assessment results. To this intent, 2.588 individuals data was collected, male and female, aged between 18 and 85 years, characterized as belonging to a clinical or non-clinical group, who took part in the survey via the internet or in person. Respondents completed the MCMI-III, a socio-demographic questionnaire and a subgroup also answered to the Goldberg General Health Questionnaire (GHQ). Besides descriptive statistics, we performed the analysis using the Student t test, principal components analysis and internal consistency. Despite difficulties related to translating very specific English terms, the assessment by judges, experts on Millon?s theory, and the back translation, attested the adequacy of the Brazilian version. Factorial analysis indicated the grouping of translated T scale items into three factors (social activities prejudice, lack of impulse control, and oppositional behavior), by presenting a single item on a fourth factor (apparently related to seeking pleasurable stimuli). The Cronbach alpha for this set of items was 0,82, indicating an acceptable scale reliability. The data analysis resulted in distinction of scores between clinical and non-clinical groups and between men and women; the relationship between high scores on the scale T and the other scales; scores of drug users according to the declared used substance; and the relationship between high scores on T and the verification of disorder or risk on GHQ mental health factor, indicating the instrument?s adequate sensistivity in identifying psychopathologies and the relationship between the different disorders or psychopathological personality patterns. Although further studies are necessary to develop the scores transformation factors, the computerized correction tool was adequate. / Millon descreve a personalidade normal em termos de estilos de adapta??o que s?o eficazes em meios normais e transtornos de personalidade como os estilos de funcionamento desadaptados. Para operacionalizar seu modelo te?rico, Millon construiu diversos instrumentos, entre eles o Millon Clinical Multiaxial Inventory III (MCMI-III), que consiste num invent?rio de auto-relato de 175 itens com resposta falso ou verdadeiro, que avalia 14 padr?es de personalidade e 10 s?ndromes cl?nicas, al?m de conter 4 escalas de verifica??o. Entre as escalas de S?ndromes Cl?nicas encontra-se a escala de Depend?ncia de Subst?ncia (T). A presente pesquisa justifica-se pela inexist?ncia de instrumentos no pa?s que avaliem os aspectos psicopatol?gicos da personalidade, e tem como objetivos traduzir e adaptar semanticamente o MCMI-III para o Brasil, verificando elementos de validade da escala de Depend?ncia de Subst?ncias, e elaborar um aplicativo informatizado que assessore a avalia??o dos resultados desse instrumento. Para tal, foram coletados dados junto a 2.588 pessoas, dos sexos masculino e feminino, com idades entre 18 e 85 anos, caracterizados como pertencentes a um grupo cl?nico ou n?o-cl?nico, que participaram da pesquisa presencialmente ou via internet. Os participantes responderam ao MCMI-III, a um question?rio s?cio-demogr?fico e um subgrupo tamb?m respondeu ao Question?rio de Sa?de Geral de Goldberg (QSG). Al?m das estat?sticas descritivas, foram efetuadas an?lises por meio do teste t de Student, an?lises de componentes principais e de consist?ncia interna. Apesar de dificuldades relacionadas ? tradu??o de termos muito espec?ficos da l?ngua inglesa, a avalia??o por ju?zes conhecedores da teoria de Millon e o procedimento de back translation atestaram a adequa??o da vers?o brasileira. A an?lise fatorial indicou o agrupamento dos itens da escala T em 3 fatores (comprometimento das atividades sociais, aus?ncia de controle dos impulsos e condutas opositivas), com a apresenta??o de um item isolado em um quarto fator (aparentemente relacionado ? busca de est?mulos prazerosos). O alfa de Cronbach para este grupo de itens foi de 0,82, indicando aceit?vel confiabilidade da escala. A an?lise dos dados obtidos resultou em diferencia??o nas pontua??es de grupos cl?nico e n?o cl?nico e entre homens e mulheres; rela??o entre pontua??es altas na escala T com as demais escalas do instrumento; diferencia??o nas pontua??es dos usu?rios de drogas de acordo com a subst?ncia declarada como utilizada; e rela??o entre as altas pontua??es em T e a verifica??o de dist?rbio ou risco no fator Sa?de Geral do QSG, indicando adequada sensibilidade do instrumento na identifica??o de quadros psicopatol?gicos e na rela??o entre os diferentes transtornos ou padr?es psicopatol?gicos de personalidade. O aplicativo de corre??o informatizado se mostrou adequado, embora ainda sejam necess?rios estudos para o desenvolvimento dos fatores de transforma??o dos escores

Tradução para a língua portuguesa e validação do instrumento de reações à doação de sangue - Blood Donation Reactions Inventory / Translation for the Portuguese language and validation of the Blood Donation Reactions Inventory scale.

Ana Carolina Garcia Braz 28 November 2013 (has links)
A escala Blood Donation Reactions Inventory (BDRI) foi originalmente proposta por Meade et al. (1996) como parte de um estudo dos preditores psicológicos de reações em doadores voluntários. É composta por 11 itens respondidos pelo doador, cada um correspondendo a uma reação ou sensação referente à doação de sangue mais recente. Na literatura, a escala BDRI é associada à probabilidade de retorno de doadores de sangue, o que sugere que o instrumento é uma ferramenta efetiva para predizer se um doador realizará novas doações. O objetivo do presente estudo é traduzir para a língua portuguesa o BDRI e estudar a confiabilidade e consistência interna desta versão traduzida, bem como sua validade de critério e de constructo. O BDRI traduzido apresentou CVI superior a 80% em todos os itens e razoável consistência interna, além de mostrar que grande parte dos doadores que apresentaram pelo menos um sintoma eram primodoadores (42%) e que mais mulheres (32%) que homens (20%) relataram algum sintoma. Concluímos que os objetivos do trabalho de traduzir para a língua portuguesa e validar o BDRI foram atingidos. Esta pesquisa traz para a língua e cultura brasileiras um instrumento útil em pesquisas na área de hemoterapia. / The Blood Donation Reactions Inventory ( BDRI ) was originally proposed by Meade et al . (1996) as part of a study of the predictors of psychological reactions volunteer donors. It consists of 11 items answered by the donor , each corresponding to a reaction or feeling related to blood donation lately. In the literature , the scale BDRI is associated with the probability of return of blood donors , suggesting that the instrument is an effective tool to predicting whether a donor will carry out further donations . The aim of this study is to translate into Portuguese languagethe BDRI and study the reliability and internal consistency of this translated version, as well as its criteria validity and construct validity. The translated BDRI showed CVI more than 80 % on all items and reasonable internal consistency and showed that most of the donors who had at least one symptom were donating blood for the first time (42%), beyond showing that women reported more symptoms (32%) than men (20%). We conclude that the objectives of the work to translate into Portuguese and validate BDRI been achieved. This research brings to the Brazilian language and culture a useful tool for research in hematology.

Implementing Full Inventory Control in a Production Facility: A Case Study at Scania CV Engine Assembly

Dipa, Fuad, Ektiren, Erkan January 2019 (has links)
The concept of inventory control has been around since the early 20th century and it’s constantly evolving. The importance of inventory management and supply chain management is clear, and companies are constantly trying to evolve their systems and ways of handling inventory control. By having a proper inventory control system with adequate inventory record audits, a company could potentially have several benefits such as reduced tied-up capital, reduced holding costs, reduced/redistributed work hours, better automation and more. Most organisations and companies have some form of inventory control, however not all have full control of their inventory. This includes automatic inventory balance updates, package traceability, automatic replenishment systems and more. To implement these ideas, a company would need to foremost find what factors are currently hindering them from obtaining this and consequently being able to adjust their factors. Since there are several ways to obtain an automatic inventory record update that is adequate, multiple proposals are discussed in this thesis project. This thesis project assessed what the necessary steps that a company needs to perform are through a case study at Scania CV Engine and a benchmarking at Scania Production Angers. Through a collection of scientific literature and empirical data, an attempt to identify the factors that determine whether a company can implement full inventory control or not was made. As a supplement to this, this thesis project also looked over what type of consequences an implementation of full inventory control could have in a company, both when it comes to purely systemic consequences as well as economic consequences. / Begreppet saldokontroll har cirkulerat sedan början av 1900-talet och teorierna utvecklas ständigt. Betydelsen av lagerstyrning och Supply Chain Management är idag tydlig och företag försöker ständigt utveckla sina system och sätt att hantera saldokontroll på. Genom att ha ordentlig saldokontroll med adekvata lagerregistreringsrevisioner kan ett företag potentiellt få flertalet fördelar som till exempel reducerat bundet kapital, minskade innehavskostnader, reducerade eller omfördelade arbetstimmar, bättre automatisering och mera. De flesta organisationer och företag har någon form av lagerkontroll, men inte alla har 100% kontroll över sina inventeringar. Detta inkluderar automatiska lagerrevisioner, spårbarhet av paket, automatiska påfyllningssystem och mer. För att genomföra dessa idéer måste ett företag framför allt finna vilka faktorer som för närvarande förhindrar dem från att uppnå 100% saldokontroll och följaktligen kunna justera dessa faktorer. Eftersom det finns flera sätt att uppnå automatiska revisioner av inventeringen som är proper så diskuteras flera förslag i denna avhandling. Denna avhandling försöker bedöma vilka nödvändiga steg som ett företag behöver genomföra är genom en utförd fallstudie på Scania CV Engine tillsammans med en benchmarking på Scania Production Angers. Genom en samling av vetenskapliga studier och empiriska data från fallstudien gjordes ett försök att identifiera de faktorer som avgöra om ett företag kan implementera 100% saldokontroll eller inte. Som ett komplement till detta ser denna rapport även över vilken typ av konsekvenser en sådan implementering kan innebära, båda när det gäller rent systematiska förändringar samt ekonomiska förändringar.

Strategic considerations for improving ESL (English as a Second Language) learning outcomes among college students in Taiwan: a case study

Pan, Telan Teresa, n/a January 2005 (has links)
There is considerable variation among individuals in the ability to learn a second language. Learning strategy research and learning style research, as two main areas of individual difference research, seek to help learners to �learn how to learn�, and ultimately become autonomous and independent learners. Learning strategy theory postulates that successful learning strategies can be used to good effect by less effective learners, and that teachers can promote good learning strategy usage through classroom instruction. At the same time, for there to be effective instruction to second language learners as to the most efficient learning strategy usage, there must be a research effort that looks not just at the strategies per se, but also gives attention to the cultural background of the students themselves. However, there has been little research into the ways in which low-achieving ESL learners can develop effective learning strategies in a non-western context. The historical, political, social and economic aspects of Taiwan make this small island a fascinating place for researchers interested in exploring how English is taught and learned in a relatively monolingual society (in the sense that Chinese Mandarin is the only official language and is predominately used all over Taiwan). Therefore, this study explores the ESL learning strategies and learning styles of 462 adult learners in Taiwan, making use of Oxford�s Strategy Inventory for Language Learning and Kolb�s Learning Style Inventory. Similarities and differences between the learning strategy usage of the high-achieving and low achieving groups are also investigated. The results show that there was no statistically significant relationship between the learner�s English proficiency level and their individual learning style. In sharp contrast, it was discovered that there was a highly significant relationship between the learner�s English proficiency level and their choice and use of various learning strategies. It was also found that the higher the English proficiency level, the greater the variety of learning strategies adopted, and the more frequently those strategies were used. This study aims to shed some light on the principles that underlie successful language learning, particularly in regards to the utilisation and accommodation of learning strategies and styles. The results of such a study could thus contribute to the field of second language learning in a number of ways: for the learner, the teacher, the school policy maker, and the researcher.

Den stora parameterjakten : Riktlinjer för skapande av en artikelklassificering ur ett logistiskt perspektiv

Hamberg, Sven, Zetterberg, Christine January 2009 (has links)
<p>Effektiv logistik är ofta nyckeln bakom framgångsrika företag. Då logistik är ett väldigt komplext problemområde har det blivit nödvändigt att utveckla intelligenta system som hjälpmedel vid beslutsfattande. Klassificeringssystem av artiklar är ett sådant system, vilket ska underlätta att flytta fokus från den enskilda artikeln till artiklar som kräver extra mycket uppmärksamhet.</p><p>En stor del forskning har utförts inom klassificeringsområdet de senaste åren. Denna har dock varit av ren matematisk karaktär där olika lösningar presenterats vilka i grund och botten behandlat skapande av en artikelrangordning utifrån en samling parametrar. Hur parametrarna väljs och vilka implikationer valet av matematisk modell får är ännu obehandlat ur ett logistiskt perspektiv. Denna rapport syftar till att påbörja fyllandet av den lucka som återfinns inom klassificeringsområdet. Detta innebär framtagande av ett systematiskt förhållningssätt vid byggande av ett klassificeringssystem, där val av parametrar och matematisk modell utgår från företagets behov och förutsättningar.</p><p>Parametrarna att bygga klassificeringen på är systemets verkliga kärna och utgör därmed grunden för de beslut som fattas utifrån det. För att klassificeringen på ett effektivt sätt ska kunna ligga till grund för beslutsfattande inom ramen för logistik krävs att hänsyn tas till företagets hela logistiska verksamhet. Parametrarna identifieras därför genom att analysera en artikels huvudsakliga kontaktytor med en organisation, där rapporten avgränsas till inköp, lager och kund. Vid de tre stegen identifieras parametrar vilka är mått på de direkta såväl som indirekta kostnader förknippade med de olika artiklarna, samt hur stort värde de tillför organisationen i stort. Valet av matematisk modell får implikationer både för det slutgiltiga klassificeringssystemets precision såväl som hur stor kostnad skapandet utgör, där mer komplexa modeller ger ett mer pålitligt klassificeringssystem samtidigt som de är mer resurskrävande att implementera.</p><p>Genom att följa rapportens riktlinjer kan ett klassificeringssystem byggas vilket möjliggör en differentierad materialhantering där operativa och strategiska beslut är väl underbyggda, och där de resurser som förbrukas i och med hanteringen av de olika artiklarna får maximal utdelning.</p>

Two-Echelon Supply Chain Design for Spare Parts with Time Constraints

Riaz, Muhammad Waqas January 2013 (has links)
We consider a single-part, two-echelon supply chain problem for spare parts. The network consists of a single manufacturing plant, a set of service centers (SCs) and a set of customers. Both echelons keep spare parts using the base-stock replenishment policy. The plant behaves as an M/M/1 queueing system and has limited production and storage capacity. Demand faced by each SC follows an independent Poisson process. The problem is to determine optimal location-allocation and optimal base-stock levels at both echelons while satisfying the target service levels and customer preferences of SCs. We develop a mixed integer non-linear programming model and use cutting-plane method to optimize the inventory-location decisions. We present an exact solution procedure for the inventory stocking problem and demonstrate the limitations of using traditional inventory models like METRIC-like and Approximate in case of high utilization rates. We show the effectiveness of our proposed cutting-plane algorithm and provide important managerial insights for spare parts management.

An Effective Implementation of Operational Inventory Management

Sellamuthu, Sivakumar 16 January 2010 (has links)
This Record of Study describes the Doctor of Engineering (DE) internship experience at the Supply Chain Systems Laboratory (SCSL) at Texas A&M University. The objective of the internship was to design and develop automation tools to streamline lab operations related to inventory management projects and during that process adapt and/or extend theoretical inventory models according to real-world business complexity and data integrity problems. A holistic approach to automation was taken to satisfy both short-term and long-term needs subject to organizational constraints. A comprehensive software productivity tool was designed and developed that considerably reduced time and effort spent on non-value adding activities. This resulted in standardizing and streamlining data analysis related activities. Real-world factors that significantly influence the data analysis process were identified and incorporated into model specifications. This helped develop an operational inventory management model that accounted for business complexity and data integrity issues commonly encountered during implementation. Many organizational issues including new business strategies, human resources, administration, and project management were also addressed during the course of the internship.

Computerized measurement of psychological vital signs in a clinical setting [electronic resource] / by Ryan K. Russon.

Russon, Ryan K. January 2003 (has links)
Title from PDF of title page. / Document formatted into pages; contains 89 pages. / Thesis (M.A.)--University of South Florida, 2003. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: Due to the increasing demands of third-party payers to show measurable results in a decreased amount of time, mental health practitioners need new tools and techniques to quickly and efficiently assess their client's current status and progress in treatment. The goal of this study was to develop and validate a brief computerized measure of emotional states and personality traits for use as an assessment tool in a clinical setting. Adapted from the State-Trait Personality Inventory (STPI; Spielberger, 1998), the computerized instrument measured state and trait anxiety, anger, depression, and curiosity. The computerized STPI was examined for equivalence with the traditional STPI and compared with therapists' ratings of their clients' emotional states and personality traits. Forty individuals (24 women, 16 men) in psychotherapy were administered either a computerized version of the STPI or the original, paper version. / ABSTRACT: Each client's therapist was asked to rate him or her on the same 4 states and 4 traits measured by the STPI. In addition, clients and therapists answered short questionnaires regarding their reactions to the STPI and the client report generated by the STPI, respectively. [BR][BR] A comparison of mean STPI scale scores between the computerized and paper administration groups showed slightly higher levels of reported state emotion for the computerized administration. There was no other evidence of differences between the two experimental groups. Therapists who had previously conducted assessment with their client demonstrated a significantly higher correlation of their ratings with the corresponding client STPI self-reported scores. Feedback from the client and therapist exit questionnaires suggested that their reactions to the procedure and the usefulness of the STPI were quite favorable. / ABSTRACT: Implications of increasing the use of computers in clinical assessment are discussed. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.
