Leadership Skills to Sustain High-Tech Entrepreneurial Ventures

Rangwala, Zoaib Z 01 January 2018 (has links)
High-tech (HT) innovation-oriented entrepreneurs start 35% more ventures and create 10% more jobs in the first 5 years of operation than the rest of the private sector and drive significant economic growth across all industries; however, more than 50% of the entrepreneurial HT ventures fail during the first 5 years of operations. Guided by the conceptual framework of transformational leadership theory, the purpose of this multicase study was to explore skills used by successful entrepreneurial leaders to sustain their HT ventures in Silicon Valley, California. Data collection was from 8 participants in semistructured 1-on-1 interviews and 3 participants in a focus group discussion. All participants were entrepreneurial leaders with experience in sustaining their entrepreneurial ventures beyond 5 years. A thematic data analysis approach involved text search, content coding to nodes, and code comparison techniques of collected data to extract themes and identify relationships in the findings. The emergent 4 leadership skill themes for HT entrepreneurial venture sustainability were the recruitment of the right team, situational adaptability, market orientation, and providing innovation stimulation. The right team can resourcefully assist the leader to execute market-leading competitive products and overcome challenges in the dynamic and intensely competitive and innovative HT industry. A culture of openness, ownership, and trust is conducive to the sustainability of an HT venture. Findings from this study may contribute to social change by promoting the formation of new HT ventures, increasing job creation, reducing work stressors, improving quality of life with innovative and cost-effective products, and services in healthcare, infrastructure, personal safety, education, and communications.

Tržní orientace a řízení vztahů k zákazníkům / Market Orientation and Customer Relationship Management

Frejková, Daniela January 2014 (has links)
The doctoral thesis is concerned with Market Orientation (MO) and Customer Relationship Management (CRM). MO and CRM have been under permanent focus of both theoreticians and practitioners in recent years as they are considered to be important for long-term business success. Surprisingly, these two strategic concepts have been examined separately. What is missing is research that would systematically analyse the possible interdependence between MO and CRM. The main aim of the doctoral thesis is to evaluate the existence of interconnections between MO and CRM. This doctoral thesis has been prepared on the basis of secondary research, as well as primary research activities. Both qualitative and quantitative methods have been applied in order to obtain a more complex view on the topic. The main primary research of this thesis was conducted through a questionnaire survey among aerospace companies in the Czech Republic. The hypotheses were tested so as to support the partial objectives, as well. The findings constitute a valuable contribution to broaden the knowledge of MO and CRM. The doctoral thesis has revealed that MO and CRM are interconnected. A tool for CRM measurement was proposed, and the level of MO and CRM in the surveyed companies was determined. The barriers to the implementation of MO and CRM were identified, yet the actual application of these concepts in practice of companies has remained an issue. The conclusions and recommendations were formulated and the contributions to the theory, practice and education were highlighted. The findings offer the possibility of further expansion of research.

Stadsbruk på nordligare breddgrader : En fallstudie över Norrlands kustlandskommuner

Gustafsson, Candra, Hedman, Anna January 2023 (has links)
Den snabbt växande urbaniseringen och den ökande befolkningen i världen har bidragit till markexploatering i städer, vilket kan ske på bekostnad av åkermarker. Ett annat fenomen som sker globalt är det ökande behovet av livsmedel som förväntas öka med 70% i takt med befolkningstillväxten. I och med Coronapandemin har det även uppdagats att Sverige endast kan försörja 50% av befolkningen vid en kris. De senaste åren har begreppet Stadsbruk vuxit fram, vilket syftar till kommersiell odling i staden. Stadsbruk har bland annat implementerats i fyra städer i södra Sverige, men för att Sverige ska öka sin självförsörjning bör Stadsbruk även fokuseras på och utvecklas i Norrland. Syftet med denna studie var att undersöka hur Stadsbruk kan etableras i större utsträckning längs Norrlandskusten för att möta den ökade efterfrågan på livsmedel i Sverige, den rådande klimat- och energikrisen och ökande markexploateringen. Målet var att få fram ett ramverk för framtida aktörer vid etablering av Stadsbruk längs Norrlandskusten. Arbetet genomfördes som en fallstudie där tre kustlandskommuner i Norrland valdes ut. Därefter utfördes en dokumentanalys och intervjuer. De aktörer som intervjuades var kommuner, forskare, ett företag inom Stadsbruk och ett riksförbund inom odling. Resultatet visade att både traditionell odling och högteknologisk odling behövs som metoder, men att högteknologisk odling bland annat ger möjligheter för större produktionsvolymer, odling året runt och ökad lönsamhet. Studien visade även att industrier längs Norrlandskusten kan integreras med inomhusodling för möjlighet till energieffektiv uppvärmning från spillvärme. De möjligheter som Norrlandskusten besitter är bland annat stora marktillgångar och möjligheterna för odling året runt inomhus med flera väletablerade industrier som kan bidra med spillvärme. En förutsättning för att Stadsbruk ska kunna etableras i större utsträckning är fler regelverk på nationell och kommunal nivå, ökad kompetens, införande av handläggare i kommunen, att företag inom Stadsbruk prioriteras och ges stöd samt att företagen inkluderas tidigt i planprocessen. / The rapidly growing urbanization and increasing population of the world has contributed to land exploitation in cities, which can occur at the expense of arable land. Another phenomenon that is happening globally is the increasing need for food, which is expected to increase by 70% in line with population growth. With the Covid-19 pandemic, it has also been discovered that Sweden can only provide for 50% of the population in a crisis. In recent years, the concept of urban agriculture has emerged, which aims at commercial cultivation in the city. Urban agriculture has, among other things, been implemented in four cities in southern Sweden, but in order for Sweden to increase its self-sufficiency, urban agriculture should also be focused on and developed in Norrland, northern Sweden. The aim of the study is to investigate how urban agriculture can be established to a greater extent along the Norrland coast to meet the increased demand for food in Sweden, the upcoming climate and energy crisis and increasing land exploitation. The objective of this study was to produce a framework for future actors when establishing urban agriculture in municipalities along the Norrland coast. The work was carried out as a case study where three coastal municipalities in Norrland were selected. A document analysis and interviews were then carried out. The actors who were interviewed were municipalities, researchers, one company within urban agriculture and a farming association. The results showed that both traditional cultivation and high-tech cultivation are needed as methods, but that high-tech cultivation offers opportunities for larger production volumes, year-round cultivation and increased profitability. The study also showed that industries along the Norrland coast can be integrated with indoor cultivation for the possibility of energy-efficient heating from industrial waste heat. The opportunities that the Norrland coast possesses are the large land assets and the opportunities for year-round indoor cultivation with many of wellestablished industries that can contribute with waste heat. A prerequisite for urban agriculture to be able to be established to a greater extent is more regulations at national and municipal level, increased competence, introduction of a manager in the municipality, that companies within urban agriculture are prioritized and given support and that the companies are included early in the planning process.

Personen framför allt : personcentrerad vård i högteknologisk hjärtsjukvård / Focus on the person : person-centred care in high-tech cardiac care

Claëson, Matilda, Hedberg, Ida January 2021 (has links)
Miljöbegreppet har i modern omvårdnadsforskning fått en allt bredare och djupare dimensiondär människan i sin miljö betraktas ur ett holistiskt perspektiv. Personcentrerad vård är ettarbetssätt där man utgår från patienten som person som inte kan reduceras till enbart sinsjukdom. Att som vårdgivare vara medveten om den fysiska miljön, personers handlingar ochhur den organisatoriska filosofin är uppbyggd skapar en större möjlighet att kunna arbetapersoncentrerat. Personcentrering är det som patienten upplever, medan personcentrerad vårdär arbetssättet som genererar patientens upplevelse av personcentrering. Personcentreratklimat är den miljö där personcentrerad vård sker. De förhållanden som formas mellanpatienten, vårdpersonal, närstående och teknik liksom miljöns atmosfär, omgivning ochomvärld, är avgörande för om patienten kommer att uppleva miljön som vårdande eller ickevårdande. Syftet med studien var att undersöka och beskriva förekomst av personcentrerad vård blandpersoner som vårdats i en högteknologisk vårdmiljö i samband med hjärtkirurgi ochhjärtsvikt. Metoden var en icke-experimentell tvärsnittsstudie som genomfördes inom högteknologiskahjärtsjukvård. Datainsamlingen utfördes med hjälp av två patientrapporterade mått: BeingTaken Seriously Questionnaire - Patient version (BTSQ-P) och Person-Centered ClimateQuestionnaire - Patient version (PCQ-P). Resultatet visade att patienterna upplevde att vården var personcentrerad utifrån att bli tagenpå allvar och att den innefattade ett personcentrerat klimat. Regressionsanalysen visade att ettsäkert klimat är den viktigaste komponenten för känslan av att bli tagen på allvar. Slutsatsen var att högteknologisk hjärtsjukvård inte enbart genererar goda medicinska resultatutan också kan bidra till personcentrerad vård. Vidare drar vi lärdom av studiens resultat medkunskapen om att ett säkert klimat är den viktigaste faktorn inom det personcentreradeklimatet, för patientens upplevelse av personcentrering. / In modern nursing research, the concept of the environment has acquired an ever broader anddeeper dimension where people in their environment are viewed from a holistic perspective.Person-centered care is a way of working that is based on the patient as a person who cannotbe reduced to his or her illness alone. As a caregiver, being aware of the physicalenvironment, people's actions and how the organizational philosophy is structured creates agreater opportunity to be able to work person-centered. Person-centeredness is what thepatient experiences, while person-centered care is the way of working that generates thepatient's experience of person-centeredness. Person-centered climate is the environment inwhich person-centered care takes place. The relationships that are formed between the patient,care staff, relatives and technology, as well as the environment's atmosphere, surroundingsand settings, are decisive for whether the patient will experience the environment as caring oruncaring. The aim of the study was to investigate the prevalence of person-centered care amongstpeople who have been cared for in a high-tech care environment in connection with heartsurgery and heart failure. The method was a non-experimental cross-sectional study conducted in high-tech cardiaccare. Data collection was performed using two patient-reported measures: Being TakenSeriously Questionnaire - Patient version (BTSQ-P) and Person-Centered ClimateQuestionnaire - Patient version (PCQ-P). The results showed that the patients felt that the care was person-centered based on beingtaken seriously and that it included a person-centered climate. The regression analysis showedthat a safe climate is the most important component for the feeling of being taken seriously. The conclusion was that high-tech cardiac care not only generates good medical results butcan also contribute to person-centered care. Furthermore, we learn from the study results withthe knowledge that a safe climate is the most important factor in the person-centered climate,for the patient's experience of person-centering.

Majid, Maria January 2023 (has links)
Due to the advancement in AAC technology, set of medical conditions can be assisted using high-tech AAC, serving more patients with varying communication needs. There need to be more studies about the acceptance of HT-AAC among individuals with complex communication needs, by understanding their attitude and behavioral intentions towards this technology. This thesis aims to extend previous literature and address the gap by exploring the perceptions of SLPs' regarding the acceptance of high-tech AAC and the perceived pitfalls associated with using HT-AAC. An exploratory research method combined with qualitative approach was chosen to answer the research questions and serve the purpose of the study. SLPs recognize the importance of HT-AAC in various aspects of their patients' lives. The findings highlight the need for comprehensive support, specialized training, and addressing implementation challenges to maximize HT-AAC acceptance and usage. By addressing these aspects, HT-AAC can enhance the communication and overall quality of life for patients with communication difficulties. / På grund av framstegen inom AAC-teknik kan uppsättning medicinska tillstånd hjälpas med hjälp av högteknologisk AAC, vilket betjänar fler patienter med varierande kommunikationsbehov. Det behöver göras fler studier om acceptansen av HT-AAC bland individer med komplexa kommunikationsbehov, genom att förstå deras attityd och beteendeintentioner gentemot denna teknik. Den här avhandlingen syftar till att utöka tidigare litteratur och ta itu med klyftan genom att utforska SLPs uppfattningar om acceptansen av högteknologisk AAC och de upplevda fallgroparna som är förknippade med att använda HT-AAC. En explorativ forskningsmetod kombinerad med kvalitativ ansats valdes för att besvara forskningsfrågorna och tjäna syftet med studien. SLPs erkänner vikten av HT-AAC i olika aspekter av deras patienters liv. Resultaten belyser behovet av omfattande stöd, specialiserad utbildning och hantering av implementeringsutmaningar för att maximera acceptans och användning av HT-AAC. Genom att ta itu med dessa aspekter kan HT-AAC förbättra kommunikationen och den övergripande livskvaliteten för patienter med kommunikationssvårigheter.

Functional proof of a flat slide valve as a 4/3-way proportional valve

Aengenheister, Stefan, Liu, Chao, Broeckmann, Christoph, Schmitz, Katharina 25 June 2020 (has links)
With a flat slide valve concept, when compared to conventional piston spool valves, reduced leakage and increased service life could be achieved. In order to achieve a reduction of leakage flows and guarantee the adjustability of the valves at the same time, a correct design of the pressure compensation is essential. The magnitude of force depends on both the operating point of the valve and the position of the slider. Due to the design of the flat slide valve, it is possible to use ceramic semi-finished products for the main stage, which consist of control plates and a slide plate. The geometries are simple enough to be inexpensively manufactured with sufficient accuracy, using a ceramic pre-product using laser cutting technology. This article introduces the concept of the flat slide valve for a proportional 4/3-way valve. The design of the valve, including the design of the metallic main stage is presented. This includes the design of the flow channels, which have to be suitable for ceramic materials. Furthermore the design of the actuator and hydraulic circuit for testing is presented. With the shown design, the function of a 4/3-way valve, known from piston spool valves, can be implemented with a linear behavior between slide plate deflection and opening flow cross section.

影響高科技研發人員過度工作因素及工作類型之探討

郭若蘭, Daphne J. L. Kuo Unknown Date (has links)
本研究旨在以Spence和Robbins(1992)工作狂熱建構中的內在驅迫因素和工作樂趣因素為基礎,並加入外在驅迫因素,來探討高科技研發人員過度工作的不同因素對於工作時數以及健康生活工作等層面變項的預測力或關聯性,最後由因素劃分出過度工作者類型,並比較不同類型過度工作者的差異性。本研究採問卷調查法,以249位台灣北部地區的高科技研發人員為樣本以及52位高科技行政人員為工作時數的對照組。研究結果發現:(1)研發人員與全國製造業工作者及高科技行政人員相較下,有顯著的過度工作現象。(2)外在驅迫因素意指源自專業工作環境而迫使個體長時數工作的各影響因素。針對研發人員,包括工作負荷過重、產業特性、組織文化酬賞等外在驅迫因素,以及內在驅迫因素,皆對過度工作具有顯著的預測力。而外在驅迫因素對研發人員過度工作的相對預測力高於內在因素。(3)對於健康生活工作三層面的影響性而言,內在因素中的內在驅迫有廣泛不利於三層面的顯著影響性而屬於健康生活工作的危險因子,內在因素中的工作樂趣則相對地於三層面皆有顯著助益而在三層面居於保護因子的角色;外在驅迫因素中的工作負荷過重,對於生活層面有顯著的不良影響,但對健康和工作沒有顯著影響。(4)辨識出三類型的過度工作研發人員,其中內在驅迫高工作樂趣低的「被驅迫狂」在各層面皆有最不利的行為表現,屬於積極的健康定義下的高危險群,內在驅迫高工作樂趣高的「幹勁狂」則較「被驅迫狂」有顯著較高的生活滿足,內在驅迫普通而工作樂趣高的「幹勁者」雖然長時數工作,但各層面狀況反而有優於全體研發人員平均值的傾向。最後,本研究針對上述研究結果做更深層的探討,並說明在個人層次和組織層次實務上的意涵。 / Two internal factors, “driveness” and “enjoyment of work” from the workaholism model of Spence and Robbins (1992), and “external force” factors were adopted to investigate the phenomenon of excessive work (defined as long hours of working) in the population of high-tech R&D professionals. The purpose of this study is to clarify the effects of these factors on high-tech R&D professionals’ working habits, as well as on their health and life styles. These factors were used to categorize high-tech R&D professionals further. The results showed (1) R&D professionals worked significantly longer hours than high-tech administrative staff and workers in manufacturing industry. (2) “Work overload”, one external force factor, compared to other factors, predicted best to R&D professionals’ hours of working. Moreover, the amount of variance explained by the external force factors was relatively larger than the internal factors. (3) Driveness was constantly found to be a risk factor for one’s holistic health, whereas the enjoyment of work was found to be a protective factor. The third factor, work overload, influenced one’s health only on one’s social life. (4) Three types of overworkers were identified: the nonenthusiastic workaholics (NWs), the enthusiastic workaholics (EWs), and the enthusiasts (Es). Among these overworkers, the NWs acted most consistently with the indicators of unhealthiness, showing that the NWs may be most vulnerable to health complaints, unsatisfied social life, and inefficient work habits. The EWs, though acted similarly as the NWs, were not as extreme as the NWs and had higher life-satisfaction than the NWs. As for Es, who also worked long hours, their health complains were the least of all workers and they had relatively healthy life styles than the other two kinds of workers. Implications of the internal and external factors on the high-tech R&D professionals, as well as the typology of the overworkers, were discussed.
