"I Fabians värld" – en reklamkampanjs dubbla effekt : Om storytelling som ledarskapsverktyg under påfrestande perioderProni, Antigona, Abbas, Najat January 2012 (has links)
Syfte: Syftet med den här uppsatsen är att beskriva hur SIBA AB:s storytelling påverkar de anställda. Uppsatsen utgår ifrån att storytelling kan ses som ett ledarskapsverktyg och undersöker därför hur de anställda påverkas av Fabian Bengtssons tillämpade ledarstil under rådande påfrestande situation föranledd av marknadsförändringar inom hemelektronikbranschen. Forskningsfrågor: Hur kan en ledare påverka de anställdas attityder till företaget under påfrestande situationer på marknaden? Hur kan storytelling fungera som ledarskapsverktyg för detta genom att öka de anställdas engagemang och intresse. Genomförande: Fallstudien på SIBA AB baseras på en kvantitativ och kvalitativ studie samt en narrativanalys av den pågående reklamkampanjen ”I Fabians värld”. Det empiriska materialet består av en enkätundersökning ställd till 75 anställda och en skriftlig intervju med Fabian Bengtsson samt en narrativanalys som innefattar fem reklamfilmer. Slutsatser: Det framgår av analyserna av det empiriska materialet att kommunikationsverktyget storytelling genom reklamkampanjen har haft en positiv påverkan på de anställda och skapat en uppfattning om ledarens ledarstil. Det framgår även att ledare genom storytelling kan påverka anställdas attityder och intresse för företaget. Detta för att reklamfilmerna har förmåga att skapa identifikation och vi-känsla som kan forma positiva känslor och en bra uppfattning om företaget vilket kan bidra till ett ökat engagemang hos de anställda. / Purpose: The purpose of this paper is to describe how the storytelling of SIBA AB affects the employees. The paper works on the supposition that storytelling is a leadership tool and hence examines how the employees are affected by the leader Fabian Bengtsson’s leadership during difficult times on the market. Research questions: How can a leader influence the employees’ attitudes towards the company during times of pressure on the market? How can storytelling work as a leadership tool in this case to higher the employees’ involvement for an interest in the company? Research method: The case study on SIBA AB is based on quantitative and qualitative methods plus a narrative analysis of the advertising campaign ”I Fabians värld”. The material was collected through a survey including 75 employees and a written interview with Fabian Bengtsson, plus a narrative analysis of five commercials. Conclusions: The analysis shows that storytelling in the advertising campaign has had a positive influence on the employees and has shaped a picture of the leader and of his leadership. The analysis also shows that leaders have the possibility to affect the employees’ attitudes and interest in the company. The reason for this is that commercials have the power to create identification and sense of belonging that can form positive feelings and a good impression of the company which can lead to an increased commitment among the employees.

INNOVATIVE TOOL-MODIFICATIONS AND TOOL SELECTIVITY IN NEW CALEDONIAN CROWS (CORVUS MONEDULOIDES)Alfredsson, Jessica January 2012 (has links)
Tool-use and tool-manufacture are thought to require high cognitive skills and have been considered as an exclusive attribute to primates. Recent observations of New Caledonian crows (NCCs) challenge this assumption. In this study 13 NCCs were tested with two different tool production tasks. The NCC either had to straighten a hook or bend a stick to retrieve food from two different kinds of tree trunks. The result showed that 3/5 birds bent sticks and used them to retrieve food and 1/5 birds straightened hooks to retrieve food. The birds managed to solve both tasks but not the birds in the control group. This indicates that NCC's tool making is a flexible innovative act and not just an innate predisposition to bend flexible material. This finding is interesting given that recent studies on human children show that below 8 years of age children fail in similar innovative tool making tasks.

Cut mark analysis of protohistoric bison remains from EfPm-27 utilizing the scanning electron microscopePollio, Cara Jean 13 April 2009 (has links)
EfPm-27 is a Protohistoric bison pound and processing site located in Fish Creek Park in Calgary, Alberta. The site exhibited the presence of metal tools and macroscopically deceptive cut marks suggesting the potential for the presence of both metal and stone cut marks. Moulds of selected cut marks from the assemblage were made and examined with the scanning electron microscope (SEM) to verify or negate the use of metal tools for butchery at the site. SEM images of the cut mark moulds reveal micromorphology that is similar to experimental and published stone tool cut mark SEM images. No evidence for the use of metal tools for butchering was identified.
Protohistoric sites research could benefit from the use of SEM analysis of cut marks to distinguish between stone and metal tool use. This would provide important secondary evidence for metal trade items in scenarios where such artifacts may be beyond recovery. Conversely, the presence of metal artifacts at a site does not necessarily imply that they were used for butchery and this assertion must be verified by the presence of metal cut marks.

Improving Tool Paths for ImpellersKuo, Hsin-Hung 02 September 2004 (has links)
Impellers are important components in the field of aerospace, energy technology, and precision machine industries. Considering the high accuracy and structural integrity, impellers might be manufactured by cutting. Due to their complex geometries and high degrees of interference in machining, multi-axis machines are requested to produce impellers.
The object of this thesis is to improve 5-axis tool paths for surface quality of impellers by smoothing point cutting tool paths in terms of linear segments and B-Splines and by using flank milling technologies with linear segment and B-Splines tool paths. Experimental results show that the surface quality of impeller blades can be improved by point cutting with smoothed tool paths and by flank milling. Moreover, the required milling time can be reduced by 18 percent and 13percent based on smoothed linear tool paths and smoothed B-Splines tool paths, respectively.

Evaluation And Selection Of Case Tools:a Methodology And A Case StudyOksar, Koray 01 February 2010 (has links) (PDF)
Today&rsquo / s Computer Aided Software Engineering (CASE) technology covers nearly all activities in software development ranging from requirement analysis to deployment.Organizations are evaluating CASE tool solutions to automate or ease their processes. While reducing human errors, these tools also increase control, visibility and auditability of the processes. However, to achieve these benefits, the right tool or tools should be selected for usage in the intended processes. This is not an easy task when the vast
number of tools in the market is considered. Failure to select the right tool may impede project&rsquo / s progress besides causing economic loss. In this thesis study, a methodology is proposed for CASE tool evaluation and selection among various candidates and the points that separate this work from similar studies in the literature are explained. Moreover, the methodology is performed on a case study.

On Applying a Method for Developing Context Dependent CASE-tool Evaluation FrameworksRehbinder, Adam January 2000 (has links)
<p>This dissertation concerns the application of a method for developing context dependent CASE-tool evaluation frameworks. Evaluation of CASE-tools prior to adoption is an important but complex issue; there are a number of reports in the literature of the unsuccessful adoption of CASE-tools. The reason for this is that the tools have often failed in meeting contextual expectations. The genuine interest and willingness among organisational stakeholder to participate in the study indicate that evaluation of CASE-tools is indeed a relevant problem, for which method support is scarce.</p><p>To overcome these problems, a systematic approach to pre-evaluation has been suggested, in which contextual demands and expectations are elucidated before evaluating technology support.</p><p>The proposed method has been successfully applied in a field study. This dissertation contains a report and reflections on its use in a specific organisational context. The application process rendered an evaluation framework, which accounts for demands and expectations covering the entire information systems development life cycle relevant to the given context.</p><p>The method user found that method transfer was indeed feasible, both from method description to the analyst and further from the analyst to the organisational context. Also, since the span of the evaluation framework and the organisation to which the method was applied is considered to be large, this indicates that the method scales appropriately for large organisations.</p>

The 2G method applied in a post-usage evaluation applicationZaxmy, Hanna January 2003 (has links)
<p>There exist several methods, which can be used for evaluation of commercially available CASE-tools. Each method has its own focus and is based on specific underlying assumptions. There have been attempts to standardise evaluation of CASE-tools; however available methods differs much from each other.</p><p>One such method, named the 2G method has been proposed, which for each application, will establish a specific evaluation framework. This framework is tailored to the organisation at a specific point in time (since an organisation will change over time). The method consists of two phases which are iterated a sufficient number of times before a stable evaluation framework will be the result. The 2G method has been successfully applied on several applications in different organisations, though only for evaluation of CASE-tools before adoption. In this dissertation we report on an application of the 2G method, which aims to evaluate a CASE-tool from a company context which has already adopted a CASE-tool. As part of this method application the 2G method has also been transferred to the organisation.</p><p>An additional issue this dissertation addresses is what kind of support a general Qualitative Research Tool will offer a method user when using the tool in a 2G method application. Likewise the goal includes to establish is what is poorly or unsupported in such tool in a 2G application.</p><p>This dissertation will show that the 2G method is applicable also in a scenario where a CASE-tool has already been adopted, and therefore demonstrate that the method also is useful in evaluation studies performed after a CASE-tool has been adopted in an organisation. From the experiences of the application points will be made concerning what kind of support one would like to have in a qualitative research tool to simplify the work during the 2G applications.</p>

Pneumatic tool hand-arm vibration and posture characterization involving U.S. navy shipboard personnelWilhite, Charles R 01 June 2007 (has links)
The United States Navy incorporates many different occupations to ensure it achieves its overall mission. These occupations are extremely diversified and present a wide spectrum of occupational exposures. Many of these exposures have been well studied and documented. However, shipboard pneumatic tool hand-arm vibration, (HAV) and how it relates to different body postures is an area of occupational exposure that has received little attention. The chief objective of this study was to assess whether there is a difference in hand-arm vibration levels, while working on one of two surface orientations (e.g., horizontal and vertical) among distinctly different pneumatic tools while cleaning or not cleaning. The design of the study evaluated three pneumatic tools cleaning both horizontal and vertical surfaces and the fourth tool only cleaning a horizontal surface. HAV levels were measured to identify the effect horizontal and vertical surface orientations had on the tool.
Five subjects were used in the evaluation of the four tools by a random sequencing order. Each subject was required to hold the tool in an idle condition, an activated without cleaning condition, and an activated cleaning condition, (surface contact) for 20 seconds each. These conditions were evaluated in two different surface orientations; horizontal and vertical (except for the 4th tool). Each subject repeated each of the cleaning/not cleaning conditions three times for a total of 7 measurements per surface. The idle condition was only conducted one time for each tool and surface. The measurements were collected from a Quest, HAVPro instrument using an accelerometer on the pneumatic tool following ISO 5349-1:2001 and ISO 5349-2:2001 methods.A three-way ANOVA (subjects by tool, by condition, (cleaning vs. not cleaning) and tool vs. condition) with replicates (not including idle conditions) was conducted on the data.
The analysis included the main effects and the interaction of tool and surface orientation. The subjects were treated as a blocking variable. All the main effects and the interaction were significant at p<0.0001, except for surface, p<0.6396. Surface orientation does not affect HAV levels in pneumatic tools.

Test-retest reliability and construct validity of Toddler NutriSTEP (registered trademark)Whyte, Kylie 09 May 2012 (has links)
This research represents phase C in the development of Toddler NutriSTEP® (Nutrition Screening Tool for Every Preschooler). NutriSTEP® is a valid and reliable screening tool designed to assess nutritional risk in preschoolers (3-5 years). A draft toddler (18-35 months) version of NutriSTEP® has recently been developed because of an expressed need. Convenience samples of caregivers were recruited across Ontario to assess the test-retest reliability and construct validity of the tool. Test-retest reliability was assessed based on total score and attribute scores using paired sample t-tests and intraclass correlation coefficients; individual questions were assessed using Wilcoxcon signed rank tests and kappa statistics. Construct validity was assessed through comparison of high-risk groups to Toddler NutriSTEP® scores, as well as through exploratory and confirmatory factor analyses. Toddler NutriSTEP® was found to be test-retest reliable and construct valid, and therefore may be used to assess nutritional risk in Canadian toddlers. / Funded by the Canadian Institutes of Health Research

Identification of tool breakage in a drilling process2015 February 1900 (has links)
In an effort to increase machining efficiency and minimize costs, research into tool condition monitoring (TCM) systems has focused on developing methods to allow for unmanned machining. For drilling processes, such systems typically use indirect approaches to monitoring the tool condition by measuring spindle torque and feed force as well as vibrations including acoustic emission (AE – mechanical vibrations faster than 100 kHz). This project aimed to advance the state-of-the-art in the area of TCM by developing a method to detect sudden tool failures in large diameter (> 25 mm) indexable insert drills. This project was a continuation of the research conducted by Mr. R. Griffin (a former MSc student), who developed a model capable of predicting long term wear trends in indexable insert drills [1]. Notably, his model was unable to react to sudden tool breakage due to tool chipping, which was addressed by this project as presented in this thesis.
In order to develop and train models able to detect sudden tool failure, an experiment was developed and installed in the field of the industry partner of this project. The experiment’s main feature was a pair of AE sensors added to the existing torque and force sensors. On this setup, experiments were conducted by drilling 2251 holes in workpieces using indexable insert drills with or without the insert breaking. When drilling holes without the insert breaking, the holes were named as good ones; and when drilling holes with the insert breaking they were named as bad holes. During the drilling process, data was collected from current sensors attached to the spindle motor and feed motor as well as from an AE sensor on the spindle and on the workpiece.
From the signals from the spindle motor current and feed motor current sensors, algorithms were developed to identify and divide the signals of drilling a hole into different sections of the drilling cycle (i.e. entrance, steady-state, exit, etc.). Steady-state time-domain features were extracted from the sensor signals measured for all holes drilled in the experiments and the extracted features were used to train and test the classifier models. These models were cross validated to determine which type of model was the best fit for the drilling data collected. The results from the classifier models show that most of the classifiers tested have the ability to identify sudden tool breakage based on the data recorded in the present study, with varying degrees of success. The naïve Bayes classifier was able to detect the most failures but suffered from a large number of falsely detected failures. Both the classification tree and linear discriminant analysis classifiers had lower failure detection rates than the naïve Bayes classifier, but did not suffer from the same amount of false positives; as such, these two classifiers had higher overall classification rates than the naïve Bayes.
These results suggest that classification tree and linear discriminant analysis methods are better suited for the drilling application and that the time-domain features should be complemented by others, such as the features extracted from the frequency domain, to accurately diagnose the tool condition. Future research should focus on extracting frequency and time-frequency domain features as these features might contain more information on tool condition. In addition, methods of examining features at the entrance and exit of the holes should be investigated as these two points in the drilling cycle are the most prone to sudden tool failure.
