產業的成熟與市場的飽和，使得產業的競爭變得愈來愈以成本和服務為導向，而激烈的市場競爭促使服務價格降低求存，以致物流業的服務素質及水準只能「將貨就價」，然而消費者意識的抬頭與服務科學的興起，使得服務品質的管理日益重要。因此，國際快遞物流企業要在提升服務及降低成本的驅動下，透過結合物流產業相關科技優勢與運用服務科學思維，找出顧客對產品及服務的喜好以增進服務效益，進而創新服務。 本研究以層級分析法(AHP)之操作步驟，找出對映客戶需求的四個服務品質構面及衡量構面的十二個準則，在建立一顧客喜好因素架構後，訪談某國際快遞物流前四十大客戶，以Expert Choice的整體階層不一致性判斷值(Overall Inconsistency Index, O.I.I)進行效度檢驗，通過一致性之問卷為32份。研究分析結果發現影響國際快遞物流顧客的喜好之準則，其權重依序是「誠實值得信賴」、「容易使用」及「遞送速度」，構面則以反應性及關懷性最為客戶所重視，並且從驚喜性構面發現，客戶在意的是持續性的改進與穩定的提供服務，而不喜歡沒有系統的改變與創新。在統計分析中，客戶重視程度離散度較大的有「遞送速度」及「誠實值得信賴」兩準則，顯示有特別重視此兩項因素之樣本群，而某些喜好因素間具有中度相關之關聯。 接著本研究為落實服務科學之思維與方法，將影響客戶喜好因素之架構結合決策支援系統，以決策支援系統的三個主要元件，資料庫、模式庫、對話管理提出概念設計，以重要性-績效矩陣(IPA)作為改善服務之排序參考，以及使用品質機能展開(QFD)作為在設計與創新服務的過程中納入客戶需求之方法；此外，也使用權重及客戶滿意度作為瞭解客戶對國際快遞物流服務之偏好程度及對方案之態度參考，使國際快遞物流企業能更有效率的提供滿足客戶個人偏好的服務。 / The maturity of industries and the saturation of markets make industrial competition more and more cost-oriented and service-oriented. To survive the keen market competition, the logistic industry has no choice but to reduce price, which leads to a lower level of service quality. With the uprising consumer awareness and service science, the management of service quality becomes more and more important. Driven by the need of higher service quality and lower cost, international logistic enterprises should combine relevant technical advantage and service science intellect to meet consumer demand, increase service efficiency, and innovate service. This research utilizes AHP method to create 4 service quality dimensions corresponding to customer demand and 12 criteria to measure these dimensions. After the establishment of customer preference framework, interview with 40 largest customer of a certain international logistic company and then examine the validity by the O.I.I. of Expert Choice. There are 32 questionnaires pass the consistency check. Analysis found that the weight of criteria which effect customer preference in sequence is “Integrity / trust worthiness”, “Easy to use”, and “speed of delivery”. As to dimensions, customers value “Respond” and “ Understand me” most. From the “Surprise” dimension we found customer need continuous improvement and steady service. Unsystematic changes and innovates are not preferred. In statistic analysis, “Speed of delivery” and “Integrity / trust worthiness” two dimensions have greater level of scatter on customer emphasis, which indicates there are some samples have special emphasis on these two factors and some factors have mid-level correlation. To practice the intellect and method of service science, this research combines the framework of factors that affect customer preference and decision support system. Concept designed by the 3 main part of a DSS : Database, Model base, and Dialog management, use IPA as the reference of service sequence improvement, and utilize QFD to bring in customer demand in the design and innovation of service. In addition, use weight and customer satisfaction as refer to understand international logistic service preference level and attitude toward programs. To bring more efficient and customer preference satisfied services.

This scenario demands deep knowledge of customers’ needs, an accurate sense of opportunity and the ability of taking risks. This is the context in which the technology and know how to change data into value information is fundamental to provide timely support for the decision process. Both modern companies’ Corporate Strategic Planning and Information Technology Strategic Planning has been coordinated built, aspiring to achieve company fundamental goal: to increase its value in long run. This work will briefly discuss some vision about corporate strategy and the necessity of alignment of this strategy with IT. Besides, we will analyze the case of a successful development and pioneer implementation of a Decision Support System in a Diagnosis Center in São Paulo. The case analysis is based on four groups of factors: Information Technology, artificial intelligence systems, human resources and organizational context. The conclusion reinforces the relevance of strategic alignment and illustrates the positive results that can be expected achieving it. / O atual ambiente de negócios crescentemente competitivo e turbulento requer das organizações modernas conhecimento profundo sobre as necessidades dos clientes e uma percepção de oportunidades e arrojo não triviais. Neste contexto, a transformação de dados em informações oportunas e precisas é fundamental para subsidiar a gestão. O Planejamento Estratégico Empresarial (PEE) e da Tecnologia da Informação (PETI) vêm modernamente sendo construídos para, de forma alinhada, atender o anseio maior da empresa, qual seja, maximizar seu valor a longo prazo. Este trabalho descreve sucintamente algumas visões sobre estratégia corporativa, sobre a necessidade de alinhamento desta estratégia com a TI e analisa o caso de implementação de um Sistema de Apoio à Decisão pioneiramente desenvolvido e implementado num grande Centro de Diagnósticos Médicos localizado na cidade de São Paulo. A análise do caso está fundamentada na literatura e nas vivências profissionais do pesquisador e fundamenta-se em quatro grandes grupos de fatores: tecnologia da informação, sistemas de inteligência artificial e do conhecimento, recursos humanos e contexto organizacional. A conclusão reitera a importância do alinhamento estratégico e ilustra os resultados positivos que dele se pode esperar.

Agila Business Intelligence System (ABIS) är en relativt ny och komplex typ av informationssystem, som kännetecknas av förkortade utvecklingstider, genom att exempelvis införa mer självbetjäning i de analytiska systemen, för att kunna möta ett behov av att analysera omvärldsfaktorer, som förändras i en allt snabbare takt. Eftersom ABIS är ett nytt och relativt outforskat område, finns ett behov av att utforska detta område. IT-investeringar är alltför ofta olönsamma och finns ett intresse av att visa på vad som bidrar till ett framgångsrikt införande av ett ABIS och på vilket sätt. Syftet med denna fallstudie var att identifiera högt rankade och gemensamma faktorer baserat på de kritiska framgångsfaktorer som belagts av tidigare forskning inom ABIS, beskriva hur dessa bidragit till ett framgångsrikt införande samt utröna skillnader och/eller likheter mellan hur dessa faktorer verkar ur kund- respektive leverantörsperspektiv. Som underlag för denna studie användes framför allt tidigare forskning kring kritiska framgångsfaktorer för Business Intelligence System. Speciellt en modell som utvecklades 2010 av Yeoh och Koronios användes som utgångspunkt för att lista de potentiella faktorer, som skulle beaktas av denna studie. Denna undersökning genomfördes som en fallstudie med hjälp av ett företag, som både levererar konsulttjänster och ABIS. En Delphipanel användes för att sortera fram framgångsfaktorer, som sedan studerades närmare genom semistrukturerade intervjuer för hur dessa kritiska framgångsfaktorer bidragit till ett framgångsrikt införande av ABIS från dels ett kundperspektiv, dels ett leverantörsperspektiv. De två faktorer som rankades högt och samtidigt delades av samtliga respondenter var: affärsvision och planer datakvalitet och dataintegritet Kundperspektivet var det styrande och leverantörens roll var ordentligt förstå kundens perspektiv, för att på så sätt framgångsrikt införa ABIS. Affärsvision och planer var av betydelse för att koppla införande till kundens målsättningar. Datakvalitet och dataintegritet var den mest betydelsefull faktorn utifrån den resursfördelningen skedde inom ett införandeprojekt för ABIS. / An Agile Business Intelligence System (ABIS) is a relatively new and complex type of information system, which is characterized by shortened development times, for by example introducing more self-service in the analytical systems, in order to meet the need to analyze the business environment, which is changing at an even faster pace. As the ABIS is a new and relatively uncharted area there is a need to explore this area. IT investments are too often unprofitable and there is an interest to show what contributes to a successful implementation of an ABIS and in which manner. The purpose of this case study was to identify highly ranked and common critical success factors based on the critical success factors faced by previous research in ABIS, describe how these contributed to a successful introduction of the system and examining differences and / or similarities between how these factors act from customer and supplier perspective. Earlier research on critical success factors for business intelligence systems was used as a basis for this study. Especially the model developed in 2010 by Yeoh and Koronios was used as a starting point to list potential factors to be considered by this study. This study was conducted as a case study with the help of a company that delivers both consulting services and ABIS. A Delphi panel was used to shortlist two success factors, which were then studied in more detail in semi-structured interviews to describe how these contributed to the successful introduction of ABIS from both a client as well as a supplier perspective. The two factors that both ranked high and were common for all respondents were: Clear vision and well-established business case Data quality and data integrity The leading perspective was the customer and the supplier role was to properly understand the customer perspective in order to successfully introduce ABIS. The vision and business case were important to link the introduction ABIS to client objectives. Data quality and data integrity was the most significant factor on the basis of the resource allocation of implementation projects for ABIS.

The Water Framework Directive (WFD) structures long-term plans for Europe's threatened water resources. Owning to the inherent and human-made complexities of the water cycle, stakeholders must move strategically to avoid crisis and restore sustainability. Yet, the reality of water resource management today is falling short on delivery. Stakeholders require strategic tools that will help them to build consensus and take action in the right direction. Using the Framework for Strategic Sustainable Development (FSSD), this study shows how Decision Support Systems can be strategically improved using a whole-systems approach grounded in basic Principles for Sustainability. In this way, stakeholders will be capable of making synchronized moves towards sustainability and thus more likely to realize the WFD’s goal of ‘good status’ for all European waterways by 2015.

La cicatrisation complète de la muqueuse, définie comme l'absence de lésions visibles par endoscopie, est considérée comme un objectif thérapeutique dans la prévention des complications associées aux Maladies Inflammatoires Chroniques de l’Intestin (MICI).Dans ce contexte, le rôle de l’apport protéique alimentaire et les besoins protéiques nécessaires à la cicatrisation ont été peu étudiés. L’objectif de cette thèse était d’évaluer l’effet du niveau d’apport protéique alimentaire sur la réparation épithéliale après un épisode inflammatoire intestinal dans un modèle murin de colite chimio-induite. Dans un premier temps, l’analyse de la progression de certains modulateurs impliqués dans le processus cicatriciel a mis en évidence que la réparation colique s’initiait et se consolidait avant que l’inflammation ne soit résolue et cela, dans un contexte où la composition du microbiote adhérent à la muqueuse était altérée de manière persistante. Les effets de trois régimes alimentaires ayant un niveau d'apport protéique différent (moyen, modérément élevé et élevé) ont ensuite été évalués sur la réparation de la muqueuse colique, ce qui a permis de montrer qu’au-delà d’un certain seuil, le niveau d’apport protéique aggravait et perpétuait l’inflammation colique. En revanche, un apport modérément élevé en protéines était bénéfique par rapport à un apport moyen, de par ses effets sur la perméabilité colique, l'hyper-prolifération cryptique, l’expression de plusieurs gènes codant pour des facteurs de réparation et sur la modulation de la composition du microbiote adhérent. Enfin, ces travaux ont montré que l’inflammation et le niveau d’apport en protéines affectaient le métabolisme protéique dans des organes non-cibles de l’inflammation colique en association avec une endotoxémie persistante.Ce travail a ainsi permis de mieux comprendre les événements locaux et périphériques impliqués dans la cicatrisation de la muqueuse colique et leur modulation par un apport majoré en protéines suite à un épisode inflammatoire aigu. / Advanced mucosal healing, defined by endoscopy as the absence of visible lesions, is considered as a therapeutic goal in the prevention of complications associated with IBD.In this context, the role of dietary protein intake and the protein requirements for mucosal healing have been poorly studied. The aim of this thesis was to evaluate the effect of dietary protein intake level on epithelial repair after an acute intestinal inflammatory episode in a murine model of colitis. Firstly, the progression analysis of several modulators involved in the repairing process showed that colonic repair can be initiated and consolidated in the context of inflamed mucosa, associated with persistent alterations of the colonic luminal environment. The effect of three diets with different levels of protein intake (average, moderately high and high) on colon mucosa repair were evaluated in the same model. This study showed that, beyond a threshold, the level of protein intake aggravated and perpetuated colitis. However, a moderately high protein intake was beneficial due to its effect on colonic permeability, cryptic hyper-proliferation, expression of multiple genes encoding repair factors, and composition modulation of the mucosal-adherent microbiota. Finally, both inflammation and dietary protein intake levels altered protein metabolism of other organs at the periphery of the inflammation in association with persistent endotoxemia.This work deepened the understanding of the events involved in the epithelial repair process and their modulation by an increase in the dietary protein intake after an acute episode of colitis.

Grammatical classification ("tagging") of words in language samples is a component of syntactic analysis for both clinical and research purposes. Previous studies have shown that probability-based software can be used to tag samples from adults and typically-developing children with high (about 95%) accuracy. The present study found that similar accuracy can be obtained in tagging samples from school-aged children with and without language impairment if the software uses tri-gram rather than bi-gram probabilities and large corpora are used to obtain probability information to train the tagging software.

A variety of tools have been developed to assist in the quantification and analysis of naturalistic language samples. In recent years, computer technology has been employed in language sample analysis. This study compares a new automated index, Scoring Sentences Developmentally (SSD), to two existing measures. Eighty samples from three corpora were manually analyzed using DSS and MLU and the processed by the automated software. Results show all three indices to be highly correlated, with correlations ranging from .62 to .98. The high correlations among scores support further investigation of the psychometric characteristics of the SSD software to determine its clinical validity and reliability. Results of this study suggest that SSD has the potential to compliment other analysis procedures in assessing the language development of young children.

The current study focus on investigating a relationship between processing variables and microstructure evolution mechanism in 304L stainless steel subjected to hot torsion. The Gleeble 3800 with Mobile Torsion Unit (MTU) is utilized in the current study to conduct hot torsion test of 304L stainless steel. Samples are rotated at 1100℃ in the shear strain rate range of 0.02s-1 to 4.70s-1 and the shear strain range of 0.5 to 4. Orientation imaging microscopy (OIM) technique is used to collect and analyze the microstructure. At low strains (≤1) and strain rate (0.02s-1), average grain size remains relatively constant, but the lengths of DSs and LABs increase within grains. These are characteristics of the dynamic recovery (DRV). With increasing strain and strain rate, the lengths of DSs, LABs and HABs increase, accompanied by the decrease of average grain size. Subgrains with HAB segments are observed. These are characteristics of continuous dynamic recrystallization (CDRX). At strain rates greater than or equal to 0.94s-1, the fraction of deformation texture is about 3 times higher than that of rotated cube texture. The average grain size increases relative to that at a strain rate of 0.20s-1, accompanied by the increase of twin length per area. This indicates that grain growth take place after CDRX. Sigma phase is not observed in the current study due to the lack of static recrystallization (SRX) and the higher cooling rate.
