THE ROLE OF MOTIVATION AND ASPIRATION IN INFORMING ENTREPRENEURIAL STRATEGY AND SUPPORTING SATISFACTION

Sorich, David Wesley January 2019 (has links)
Owner-operators are business owners that began grass-roots efforts to satisfy a need for potential customers i.e. develop a solution for a problem in which customers are willing to pay the owner-operator instead of doing it themselves. The problem and solution may be thought of in terms of a singularity for the customer, however this is not the case. A dichotomy exists where both the owner-operator and the customer have problems and desire solutions based on their individual self-interests. The owner-operators’ problems are manifested in motivations and aspirations and their solutions are displayed as satisfaction. The list of existing motivations and aspirations is too numerable to manage along with the amount of potential solutions. For the pilot study, an attempt was made to categorize the motivations into more manageable groups to ascertain any potential relation with success. The pilot study did not lead to any conclusive results concerning the relationship between motivation and success. However, the pilot study did reveal an associating element between motivation and success i.e. a relation between the problem and solution. That connection was strategy. Strategy was the aid that allowed the gratification to occur. The decision of the owner-operator to choose either a differentiated strategy or cost leadership (low-cost) strategy (Porter, 1980) allowed them to use a more common element where the distinctive nature of the motivations and aspirations was downplayed. The import of this relationship comes into existence depending on how interested various governing and business support bodies are in developing policies whose purpose is to create and/or aid new and existing business ventures (Hamilton, 1987). A continuous review of motivations, aspirations and their relationship with strategy is warranted as older studies become dated, not to history, but due to the fact that economies are in constant flux and as economies change (Hamilton, 1987), so do strategies, motivations, and aspirations. The pilot study focused on success as the resulting construct. During the analysis stage of the pilot study, it was noted that success among various entrepreneurs was difficult to compare and measure across individuals and industries. The result was to shift the construct from success to satisfaction, as it would allow for a simpler definition and better comparisons across entrepreneurs. The question that this dissertation attempts to answer is: What role does motivation and aspiration play in informing entrepreneurial strategy and supporting satisfaction? / Business Administration/Strategic Management

Optimering av aspirationsanläggning hos Viking Malt Ab : Optimering av aspirationsanläggning hos Viking Malt med fokus på frekvensstyrning och spjällreglering

Westh, Andy, Johansson, Jesper January 2016 (has links)
This thesis has reviewed two aspirationssystems at Viking Malt in Halmstad, Sweden. Based on this different optimization solutions has been developed for aspirationssystem 180 and 901. Viking Malt has several of plants and is the fifth largest producer of malt in Europe. As a company they constantly strive to be an energy efficient company to compete on the market. During 2015 over 200 00 ton of malt was delivered from the plant, enough to brew 1,6 billion liter of beer. From the corn reception to the finished malt, large portions of dust are created. This has to be taken care of to avoid danger of fire and to ensure a clean product. This is achieved by exhaust fans who aspirate the dusty air from the process steps where its needed, with big filters the dust is separated from the air. In the plant frequency converters are installed on aspirationsline 180 and 901 these are currently set to have the same max and min frequency, which means no speed control is currently active on the fans. The reason behind this is because consultants have not come up with any concrete solution proposals to Viking Malt so the issue has been put aside. To investigate the aspirationssystem and to clarify the problem with the frequency converters has measurements of airflow and tests with the frequency converters been done. Through treatment of earlier investigations of the aspirationssystem, discussion with the employees and new survey efficiency proposals has been identified. From calculations and investigations of the aspirationssystem three different options has been presented. The thesis has designed an action plan that Viking Malt may use as a tool to identify which option is the most relevant. / Examensarbetet har systemgranskat och bearbetat fram optimeringsmöjligheter på Viking Malts aspirationssystem på linje 180 och 901 i Halmstad. Viking Malt har ett flertal anläggningar i Norden och är Europas femte största maltproducent. Företaget strävar ständigt efter att effektivisera driften och kvalitén för att kunna vara konkurrenskraftig på marknaden. Under 2015 levererades över 200 000 ton malt från anläggningen vilket skulle räcka till att brygga 1 600 000 m3 öl. Från kornmottagning till färdigställd malt sker det stora dammbildningar som måste ledas bort för att undvika explosionsrisker och försämring av produktens kvalité. Detta uppnås med hjälp av frånluftsfläktar som aspirerar dammfylld luft ifrån processteg där behovet finns, och med hjälp av aspiration kan damm extraheras från luften. I anläggningen sitter det frekvensomformare på linje 180 och 901 som idag har samma max och min frekvens vilket betyder att det inte sker någon varvtalsreglering på fläktarna. Anledning till denna åtgärd är att aspirationen inte fungerar som den ska. För att undersöka aspirationsanläggningen och klargöra problematiken med styrningen har mätningar av luftflödet samt test av frekvensomformare utförts. Genom studera tidigare utredningar, ny kartläggning av aspirationslinjerna och diskussion bland personal har optimeringsförslag identifierats. Utifrån tryckfallskalkyler av aspirationslinjerna 180 och 901 har tre ändringsförslag presenterats. Examensarbetet har även utformat en handlingsplan som Viking Malt kan använda som ett verktyg för de åtgärder som blir relevant. Med implementering av något av de tre åtgärdsförslagen blir systemet anpassat efter erfordrat tryckfall, detta innebär att produktkvalitet kan säkerställas. Utöver detta finns det möjlighet till energibesparing upp till 23,2 MWh/år beroende av optimeringsåtgärd.

Preoperativ omvårdnad i samband med fasta inför kirurgi

Jegendal, Ulrika, Pettersson, Emilia January 2019 (has links)
Bakgrund: Preoperativ fasta är nödvändigt innan anestesi för att reducera magsäckens innehåll och därmed minska risken för aspiration. Trots att internationella riktlinjer rekommenderar två timmars fasta för klar vätska är det många sjukhus som fortfarande använder sig av rutinmässig praxis att låta patienter fasta från midnatt. Detta kan innebära en onödigt lång fasta som ger patienten komplikationer i form av sekundära biverkningar och insulinresistens. Syfte: Att undersöka preoperativ omvårdnad i samband med fasta inför kirurgi. Metod: En litteraturstudie med beskrivande design bestående av 14 utvalda originalartiklar från databaserna Pubmed och Cinahl användes. Den teoretiska referensramen för denna studie var Katie Erikssons omvårdnadsteori gällande förståelse av lidande och lidandets drama. Resultat: Många patienter fastade längre än American Society of anesthesiologists (ASAs) rekommenderade riktlinjer. Att fasta längre än två timmar innan operation minskade inte risken för aspiration och gav inte någon mindre volym av magsäckens innehåll hos patienterna. Att ge patienter kolhydratrik dryck innan operation ökade patienternas pre- och postoperativa välbefinnande och innebar inga risker. Slutsats: Genom ett mer flexibelt arbetssätt vid planerad operation kan längden på fastan anpassas efter patientens individuella behov. I samband med planerad kirurgi kan kolhydratrik dryck vara ett bra komplement vid fasta för att minska patientens lidande. Sjuksköterskan är omvårdnadsansvarig och ska arbeta evidensbaserat samt se till patienternas bästa och tillgodose deras behov. Sjuksköterskan kan använda detta som underlag för att minska lidandet i samband med fastan. / Background: Preoperative fasting is necessary before anesthesia to reduce gastric contents and decrease the risk of aspiration. Although international guidelines recommend two hours fasting of liquids, many hospitals still practice nil-by-mouth after midnight. This might give an unnecessarily prolonged fasting which give the patient discomfort and insulin resistance. Aim:  To examine preoperative care in connection with fasting prior to surgery. Method: A literature study with descriptive design based on 14 original articles selected from the databases Pubmed and Cinahl was used. The theoretical frame of reference for this study was Katie Eriksson's nursing theory regarding understanding of suffering and the drama of suffering. Results: Many patients fast longer than American Society of anesthesiologists (ASAs) recommended guidelines. Fasting more than two hours before surgery did not decrease the risk of aspiration and did not decrease the gastric volume. To give patients a high carbohydrate drink before surgery increased the patient's pre- and postoperative comfort. Conclusion: Through a more flexible working method during the planned operation, the length of the fast can be adapted to the patient's individual needs. In conjunction with planned surgery, carbohydrate-rich beverages can be a good complement to fasting to reduce the patient's suffering. The nurse is responsible for nursing care and should work evidence-based and ensure the patients' best and meet their needs. The nurse can use this as a basis for reducing the suffering associated with fasting.

Larynxmask : - en metod för att möjliggöra fri luftväg och adekvat ventilation / Laryngeal mask airway : - a method to secure the airway management and adequate ventilation

Björnstad, Maria, Karlsson, Linda January 2012 (has links)
Ofri luftväg kan uppstå på grund av bakåtfallen tunga hos den medvetslösa patienten eller om luftvägen blir tilltäppt av sekret, blod, maginnehåll eller främmande kropp. Att kunna säkerställa fri luftväg hos den medvetandesänkta patienten är en kompetens som varje anestesisjuksköterska måste behärska för att kunna säkerställa adekvat ventilation. Syftet med studien var att beskriva om larynxmask (LMA) är en patientsäker metod för att skapa fri luftväg och upprätthålla adekvat ventilation. Studien genomfördes som en litteraturstudie där 19 vetenskapliga artiklar analyserades. Resultatet av de granskade artiklarna gav följande fem teman; LMA är en säker metod för att skapa fri luftväg, LMA är en säker metod för att upprätthålla adekvat ventilation, personalens kompetens vid användning av LMA, aspirationsrisk vid användning av LMA med undertema LMA vid övervikt samt LMA vid elektiva- och akuta situationer. Litteraturstudiens resultat visar att LMA är en säker metod för att skapa fri luftväg och upprätthålla adekvat ventilation. Framtida studier skulle kunna belysa om LMA kan användas vid kirurgi till patienter med ökad aspirationsrisk, till exempel vid sectio och obesitaskirurgi. Studier skulle också kunna fokuseras på patienternas postoperativa upplevelser av att ha haft LMA jämfört med trakeal intubation. / Airway obstruction can in the case of an unconsciousness patient be caused by the tounge that falls back in the throat or by secretion, blood, stomach fluid or foreign body. The knowledge of airway management of the unconsciousness patient is a necessary qualification in every nurse anesthetist. The purpose of this study was to describe if laryngeal mask airway is a safe method to establish a secure airway and adequate ventilation. The study was performed as a literature study in which 19 articles were analysed. During the analyse five themes occurred: LMA is a secure way for airway management, LMA is a secure way to maintain adequate ventilation, the staff competence when using LMA, the risk of aspiration when using LMA with subtheme LMA in overweight and LMA in elective and acute situations. The result of the study shows that LMA is a secure way to establish a safe airway and adequate ventilation. Further studies could study if LMA can be used to elective patients with increased risk of aspiration, for example in cesarean and obesity surgery. Studies could also focuse on the patients´ postoperative experiences between LMA and tracheal intubation.

Questions de phonologie et phonétique en népalais : la rétroflexion et la double corrélation de voisement et d'aspiration. / Aspects of Nepalese phonetics and phonology : Retroflexion and the double correlation of voicing and aspiration

Khatiwada, Rajesh 30 January 2014 (has links)
Notre thèse traite de la rétroflexion et de la corrélation double de voisement et d’aspiration tant du point de vue phonétique que phonologique. En utilisant la palatographie et la linguographie directes, nous avons montré que les coronales simples sont produites majoritairement comme des lamino-dento-alvéolaires, les affriquées comme des lamino-alvéolaires, et enfin que les rétroflexes varient entre le type cacuminal et le type rétroflexe. Les différentes modélisations phonologiques des segments coronaux ont été examinées et confrontées à nos résultats dans une perspective de phonologie de laboratoire. Renvoyant principalement au mouvement vertical de la pointe de langue, nous avons proposé un trait [rétroflexe], en tant que trait de manière rattaché au noeud coronal. L’étude de la corrélation de voisement et d’aspiration a d’abord été menée au niveau acoustique. Le modèle ACT (Mikuteit & Reetz 2007) que nous avons utilisé, nous a permis de décrire acoustiquement les quatre types d’occlusives du népali tant du point qualitatif que quantitatif. Cependant, l’ACT (After Closure Time) n’a pu être utilisé comme paramètre unique pour les distinguer alors qu’il était suffisant en bengali. Nous avons ensuite mené une étude des contraintes cooccurrencielles entre occlusives aspirées, en nous fondant sur l’analyse du dictionnaire népali en ligne de R.L. Turner (1931). Nous avons pu dégager la généralisation suivante : hormis certaines racines contenant les séquences de type /Tʰ…h/ (où Tʰ = n’importe quelle occlusive aspirée et sourde), les occlusives aspirées sont absentes des affixes et les combinaisons de racines et d’affixes contiennent au maximum une aspirée. / Our thesis deals with the retroflexion and the voicing and aspiration contrasts in Nepali from a phonological and phonetic point of view. Using palatography and linguography, we showed that dentals are mainly produced as lamino-denti-alveolar, affricates as lamino-denti-alveolar and, at last, that retroflexes vary, being either cacuminal or retroflex.Various phonological models of coronal features were examined and compared in the light of our articulatory results in a Laboratory Phonology perspective. Referring mainly to the vertical movement of the tip of the tongue, we proposed the feature [retroflex], as a manner feature attached to the coronal node. The study of the voicing and aspiration contrast was first done at the acoustical level. The ACT model (Mikuteit & Reetz 2007) provides us for a useful tool to describe acoustically the four types of stops in Nepali, from a qualitative as well as a quantitative point of view. However, ACT (After Closure time) could not be used as a single parameter to distinguish them, while it was sufficient in Bengali. Finally, we performed a study of co-occurrence constraints between aspirated stops, based on the analysis of the online Nepali dictionary of R. L. Turner. We could extract the following generalisation: except in some roots including sequences such as /Tʰ…h/ (where Tʰ= any aspirated unvoiced stops), the aspirated stops are not found in affixes and combinations of roots and affixes contain maximally one aspirated stop.

A Comparison of Short-Term Systematic Desensitization and Implosive Therapy under Therapeutic Level of Aspiration

Brooks, Franklin Ramon 05 1900 (has links)
Systematic desensitization and implosive therapy have surfaced as two of the primary behavioral therapy techniques to decrease phobic responses during the past decade. Although attempts have been made to compare the efficiency and effectiveness of these two techniques, results have been unclear because of the failure of researchers to duplicate the procedures as described by their respective originators. This experiment is designed to explore the joint effects of the therapies and level of therapeutic aspiration. A second objective, and a byproduct of the data produced in achieving the primary objective, was to analyze the goal discrepancy and attainment discrepancy scores accruing throughout the therapy sessions. Several hypotheses were advanced. Further analysis of the three criterion measures by means of ANOVA resulted in significant main sessions effects for each of the three independent analyses. Results suggest that all subjects, regardless of treatment subgroup, did make significant therapeutic gains in their approach scores, fear thermometer scores, and speed of approach scores from the first to the last session. Possible explanations for results were discussed. Furthermore, approach test absolute goal discrepancy, fear thermometer absolute goal discrepancy, approach test absolute attainment discrepancy, and fear thermometer absolute attainment discrepancy scores were calculated for all goal-setting subjects. Results from independent ANOVA suggest that the typical university student is able to make fairly accurate and consistent predictions concerning his future behavior, based on his past experiences.

Quantifying Uncertainty in Low Velocity Human Aspiration Studies: Effect of Secondary Aspiration and Thin-walled Reference Sampling in Low Velocity Conditions

Anderson, Kimberly Rose 01 July 2013 (has links)
In order to evaluate a biologically relevant measure of exposure, inhalable samplers are designed to match the aspiration efficiency of the human head. Human inhalability is evaluated in wind tunnel studies using mannequins as human surrogates or using numerical and computational methods. There has been differences between human aspiration efficiency estimates using wind tunnel studies and computational fluid dynamics (CFD) modeling, particularly for larger particle sizes (>68 µm). The objective of this dissertation was to evaluate biases in low velocity inhalability studies in an effort to explain the discrepancies in results between experimental and computational inhalability studies. This research addressed the phenomena of secondary aspiration on human facial skin, evaluated the appropriateness of mannequin surfaces as surrogates for humans, and evaluated the performance of the thin-walled reference sampler in low velocities to quantify potential biases in low velocity inhalability studies. The first study determined a realistic coefficient of restitution (CoR) for human facial skin over a range of ages under nine environmental conditions. This study found human facial skin is non-uniform across the face and identified significant interaction between age and sampling location, indicating that how CoR varies with age is dependent on the location sampled. The second study applied the average CoR values for forehead, cheeks and nose in CFD simulations to evaluate the effect of secondary aspiration on human aspiration efficiency estimates and determine how refined the CoR value needed to be to accurately model human aspiration efficiency. This study identified significant increases in aspiration when allowing for particle bounce, but no significant differences between uniform CoRs of 0.5, 0.8 and 1.0, indicating differences between different mannequin surfaces and particle interactions would have minimal effect on aspiration efficiency estimates. The third study evaluated the performance of a horizontally-aligned reference sampler in low wind speeds (0.1 to 0.4 m s-1). While significant differences from unity were identified, differences ranged from -1 to 6% and would have a negligible effect on sampler efficiency estimates. The use of a horizontally-aligned isokinetic reference sampler was found to be appropriate in freestream velocities ranging from 0.1 to 0.4 m s-1.
