[pt] Raizeiras e raizeiros do Cerrado se organizaram em torno de uma rede política e socioambiental, a Articulação Pacari, desde 1999, a partir de um processo marcado por tensões e assimetrias entre reivindicações interrelacionadas de direito sobre a medicina tradicional, a identidade, o acesso ao conhecimento e à biodiversidade feitas por esses sujeitos e a expansão de dinâmicas da propriedade do conhecimento e da vida. Este trabalho reflete sobre processos de (re)(des)constituição do compartilhamento do conhecimento de plantas medicinais de raizeiras e raizeiros, na interface com conexões globais. Para alcançar esse objetivo central, primeiramente, discute-se como se constroem dinâmicas da propriedade do conhecimento e da vida, a exemplo das interrelações entre patente, biomedicina e propriedade material, a partir de uma abordagem teórica interdisciplinar. Em segundo lugar, é analisado o processo de criação da Articulação Pacari a partir das suas relações locais, regionais e globais. Em terceiro, são investigadas dinâmicas políticas, normativas e sociais de construção da identidade de raizeiras e raizeiros integrantes da Articulação Pacari a partir do cotidiano e de histórias de vida. Em quarto lugar, são discutidos aspectos teórico-conceituais sobre as interrelações entre identidade, compartilhamento e apropriação do conhecimento de plantas medicinais e cuidado. Por último, são analisadas dinâmicas de constituição do compartilhamento do conhecimento de plantas medicinais de raizeiras e raizeiros integrantes da Articulação Pacari a partir do cotidiano e de histórias de vida. Emprega-se uma abordagem qualitativa e interdisciplinar e se utiliza fontes primárias (normas, documentos, entrevistas, observação participante, imagens) e secundárias (literatura acadêmica). Argumenta-se que as formas de compartilhamento do conhecimento de raizeiras e raizeiros têm sido (des)(re)constituídas de modo heterogêneo e estratégico, a partir de interrelações de gênero, classe, raça, ecologia, fé e cuidado. A pesquisa, dessa forma, contribui para a compreensão da forma como processos de reivindicação de direitos e modos de vida de raizeiras e raizeiros são afetados pela expansão global da propriedade do conhecimento e da vida e como essas dinâmicas geram possibilidades de reconstrução epistemológica e ontológica. / [en] Herbalists from the Cerrado of Brazil have organized themselves around a political and socio-environmental network, the Articulação Pacari, since 1999, from a process marked by tensions and asymmetries between interrelated claims of rights over "traditional medicine", identity, access to knowledge and "biodiversity" made by these subjects and the expansion of dynamics of ownership of knowledge and life. This research reflects on processes of (re)(de)constitution of the sharing of knowledge about medicinal plants of herbalists, at the interface with global connections. To achieve this central objective, it first discusses how the dynamics of the ownership of knowledge and life are constructed, such as the interrelations between patent, biomedicine and material property, from an interdisciplinary theoretical approach. Secondly, it analyzes the process of creation of the Articulação Pacari from its local, regional and global relations. Third, it investigates political, normative and social dynamics of identity construction of herbalists members of the Articulação Pacari from a daily life and life stories perspective. Fourth, it discusses theoretical and conceptual aspects of the interrelationships between identity, sharing and appropriation of knowledge of medicinal plants, and care. Finally, it analyzes the dynamics of the constitution of the sharing of knowledge about medicinal plants of herbalists members of the Articulação Pacari also from a daily life and life stories perspective. The research employs qualitative and interdisciplinary approach and uses primary (norms, documents, interviews, participant observation, images) and secondary sources (academic literature). It is argued that the forms of sharing of knowledge and practices around medicinal plants of herbalists have been (de)(re)constituted in a heterogeneous and strategic way, based on interrelationships of gender, class, race, ecology, faith and care. The research thus contributes to the understanding of how processes of claiming rights and ways of life of herbalists are affected by the global expansion of the ownership of knowledge and life and how these dynamics generate possibilities for epistemological and ontological reconstruction.

Today's environment is filled with the proliferation of cyber-attacks that result in losses for organizations and individuals. Hackers often use compromised websites to distribute malware, making it difficult for individuals to detect. The impact of clicking through a link on the Internet that is malware infected can result in consequences such as private information theft and identity theft. Hackers are also known to perpetrate cyber-attacks that result in organizational security breaches that adversely affect organizations' finances, reputation, and market value. Risk management approaches for minimizing and recovering from cyber-attack losses and preventing further cyber-attacks are gaining more importance. Many studies exist that have increased our understanding of how individuals and organizations are motivated to reduce or avoid the risks of security breaches and cyber-attacks using safeguard mechanisms. The safeguards are sometimes technical in nature, such as intrusion detection software and anti-virus software. Other times, the safeguards are procedural in nature such as security policy adherence and security awareness and training. Many of these safeguards fall under the risk mitigation and risk avoidance aspects of risk management, and do not address other aspects of risk management, such as risk transfer. Researchers have argued that technological approaches to security risks are rarely sufficient for providing an overall protection of information system assets. Moreover, others argue that an overall protection must include a risk transfer strategy. Hence, there is a need to understand the risk transfer approach for managing information security risks. Further, in order to effectively address the information security puzzle, there also needs to be an understanding of the nature of the perpetrators of the problem – the hackers. Though hacker incidents proliferate the news, there are few theory based hacker studies. Even though the very nature of their actions presents a difficulty in their accessibility to research, a glimpse of how hackers perpetrate attacks can be obtained through the examination of their knowledge sharing behavior. Gaining some understanding about hackers through their knowledge sharing behavior may help researchers fine-tune future information security research. The insights could also help practitioners design more effective defensive security strategies and risk management efforts aimed at protecting information systems. Hence, this dissertation is interested in understanding the hackers that perpetrate cyber-attacks on individuals and organizations through their knowledge sharing behavior. Then, of interest also is how individuals form their URL click-through intention in the face of proliferated cyber risks. Finally, we explore how and why organizations that are faced with the risk of security breaches, commit to cyberinsurance as a risk management strategy. Thus, the fundamental research question of this dissertation is: how do individuals and organizations manage information security risks?

In der Privatwirtschaft ist Geschäftsprozessmanagement (GPM) mittlerweile verbreitete Praxis. Mit den stärker wirkenden demografischen Veränderungen, dem zunehmenden Kostendruck, dem daraus folgenden Ressourcenmangel sowie den gestiegenen Dienstleistungsansprüchen der Verwaltungskunden nimmt die Bedeutung von Wissensmanagement und GPM auch in der öffentlichen Verwaltung zu. Trotz eines größtenteils einheitlichen Gesetzesrahmens werden in der Verwaltung Geschäftsprozesse unterschiedlich ausgestaltet. Zwischen Projekten, die Verwaltungsprozesse zum Gegenstand haben, gibt es zu wenig Austausch von Expertise und Erfahrungen. Die Erkenntnisse aus der erfolgreichen Umsetzung von Prozessmanagement in der Privatwirtschaft sind nicht ohne weiteres in die Verwaltungspraxis übertragbar. Daher widmen wir uns in einem zweiten Beitrag verschiedenen Umsetzungsstrategien von GPM in der öffentlichen Verwaltung in Europa. Vor dem Hintergrund der derzeitigen Implementierung bzw. des Reifegrads von GPM in einzelnen Verwaltungen ist GPM längst kein integraler Bestandteil der Organisationen. Insbesondere ist die Bereitschaft, Wissen über Geschäftsprozesse zu teilen, ist sehr begrenzt. Wir untersuchen in einem weiteren Beitrag, welche Umstände, Treiber und Hemmnissen den Prozesswissens-Austausch in öffentlichen Organisationen beeinflussen. In einem abschließenden Beitrag stellen wir die wesentlichen Bausteine eines föderalen Informationsmanagements in der öffentlichen Verwaltung in Deutschland dar. Dabei haben wir untersucht, wie Daten und Informationen aus den Bereichen Leistungen, Prozesse und Formulare der öffentlichen Verwaltung miteinander zu kombinieren und zu integrieren sind. / Business Process Management (BPM) is already widely used in the private sector. The importance of knowledge management and BPM in the public administration also increases due to the advancing demographic change, the increasing cost pressures, the consequent lack of resources as well as the increased demand of customers for administrative services. Despite a uniform legal framework, the business processes are executed differently in different administrations. There is little exchange of expertise and experience between BPM projects. The goal of the research project “National Process Library” (NPL) is to create a platform to exchange and reuse processes and BPM expertise about and among German administrations. For the dissertation at hand, essential design elements of this platform have been designed and have been subject to a first evaluation. Many findings about the successful implementation of process management in the private sector cannot be directly transferred to the public administration, as there exist important differences. Hence, the second contribution focuses on the different implementation strategies of BPM in public administrations in Europe. The current degree of implementation and maturity of BPM in public administrations is generally low. Many administrations face similar challenges and offer identical or overlapping services. However, the willingness to share knowledge about business processes is very limited. Therefore, the exchange of process knowledge could lead to immense savings. The third contribution investigates the circumstances, drives and inhibitors to improve process knowledge sharing in public organizations. The last contribution represents the essential components of a federal information management in the public administration in Germany. The derived framework combines and integrates data and information from the areas of services, processes and forms of public administrations.

知識分享是實現成功知識管理的關鍵步驟，然而在公共組織中的成員，當他們去分享自己的知識時，不僅需要花額外的時間和努力之外，甚至可能還會減少他們自己在組織中的權力地位和競爭價值，因此將成員個體的知識轉換組合成組織整體的知識，相形之下會更不容易達成。故本研究的目的在於瞭解哪些因素會影響公共組織成員中的知識分享行為，因此本研究模式中的構念係根據社會交換理論、社會資本理論以及計畫行為理論為基礎。 / 本研究根據這些相關理論所提出之構念發展出涵蓋社會心理(例如外在報酬、預期互惠及樂於助人)、組織系絡(例如認同、信任及支持分享的規範)以及資訊科技(例如資訊科技使用)等三組因素層面的整合性研究模式，並認為這三組因素層面下的變數都會影響成員的知識分享行為。而本研究對象為台北市政府所屬之一級行政機關單位的員工，經過叢聚隨機抽樣後，抽出16個市府所屬之一級行政機關單位中850位受訪者，有效問卷數為524份。而本研究採取結構方程模式(SEM)途徑來檢定本研究模式之假設關係與模式配適程度。 / 研究結果除了發現本研究模式配適度良好外，也發現模式內生變數部份中的知識分享意圖與知識分享行為有高度的正面影響關係，而知識分享的態度、主觀規範與行為控制認知對於知識分享意圖也有正面的影響關係。而模式外生變數部份，預期互惠、樂於助人和組織認同感對於知識分享態度有直接的正面影響；此外組織信任和支持分享的規範對於知識分享的主觀規範有直接的正面影響；還有資訊科技使用對於知識分享的行為控制認知有直接的正面影響，而令人訝異的是在本研究中的外在報酬對於知識分享態度卻是直接的負面影響。 / 因此基於這些研究結果的發現，認為增加員工間的知識分享行為和參加知識分享活動是和正面的社會互動文化有所關聯，因此除了型塑出彼此相互信任、認同的組織氣候或文化之外，也必須建構出易於知識分享的組織規範(如創新、團隊合作和尊重多元價值等)。然而知識分享主要是人與人之間的社會交換活動，因此還要強化成員分享知識的內在動機(如樂於助人)。所以鼓勵公共組織中的管理者和員工彼此間能夠保持頻繁的社會互動，以建立彼此間的人際信任與預期互關係，還有對組織整體的認同與信任，以促使成員產生分享知識的意圖。最後給組織中的公共管理者與政策制定者一個啟示，知識分享還是需要有一個知識分享環境或文化，因此管理者應該確保有效地創造出易於知識分享的環境或文化，以促使知識分享行為的產生。 / Knowledge sharing is a critical step for successful knowledge management. However, sharing knowledge not only requires time and effort but also reduces value or power in the public organization. Therefore, individual’s knowledge does not transform easily into organizational knowledge. The purpose of this study is to develop an understanding of the factors affecting the individual’s knowledge sharing behavior in the governmental context. The research model includes various constructs based on social exchange theory, social capital theory , and the theory of planned behavior .Hence, this research developed an integrated theoretical model and unveiled three sets of critical factors: psychological(extrinsic rewards, reciprocal relationships, enjoyment in helping others), organizational (identification ,trust , pro-sharing norm)and technological(information technology usage) that are believed to affect the knowledge sharing behaviors. Data collected from 524 employees in Taipei City Government were conducted to test the research model using the structural equation modeling (SEM) approach. / The results of the study provide empirical support for the overall structure theorized in the research model. Knowledge sharing behavior was predicted by the employees’ intention towards knowledge sharing and perceived behavioral control. Knowledge sharing intention in turn was predicted by employees’ attitude towards knowledge sharing, subjective norm and perceived behavioral control. The employees perceptions of reciprocal relationships, enjoyment in helping others and identification were positively associated with favorable attitude towards knowledge sharing. The perceptions of extrinsic rewards exerted a negative effect on the attitude. Organizational trust and pro-sharing norm positively influenced employees’ subjective norm. Additionally, information technology usage was positively associated with high levels of perceived behavioral control towards knowledge sharing. / Based on the findings, the study indicates that an increased effort to encourage employees to participate knowledge sharing activities is associated with a positive social interaction culture. Specifically, reinforcing individual’s intrinsic motivation and creating an organizational context characterized by trust, identification and pro-sharing norm are likely to encourage both management and employees to socialize and interact frequently with each other by means of driving knowledge sharing intention. Finally, the study has implications for public manager and policy maker to formulate policies and appropriately to ensure the effective creation of a knowledge sharing culture.

知識不同於一般的商品，其具有無形、內隱與價值不易判斷等特質，組織很難以權威、命令、或單以金錢的方式來要求員工主動分享其專屬的知識，以提高組織內知識運用與創造的循環。人力資源制度涵蓋整體企業，各項措施與內部員工息息相關，而員工個人主觀的支持知覺和對上司的信任態度，對其知識分享(Knowledge sharing)的行為存在可能的影響。本研究以社會交換理論為基礎，透過階層線性模式(Hierarchical Linear Modeling)的統計方法，以Snell & Dean(1992)提出的五種高承諾人力資源措施構面為組織層次變項，同時參考Eisenberger(1986）與Robinson(1994)所提出的知覺組織支持(POS)與信任(Trust)為個體層次的預測變項和中介變項，驗證跨層次與單一層次的變項對組織員工知識分享行為的影響。 本研究將問卷分為主管問卷與基層問卷，透過書面郵寄與電子郵件的方式進行發放，對象為台灣國內27家金融機構的管理人員與一般員工，參與本研究的公司涵蓋銀行、證券、保險、投信、郵局與期貨公司。我們經由實證分析，得到了以下的研究發現： 一、 員工的知覺組織支持的認知程度愈高，其採取知識分享的意願與行為也會愈高。 二、 員工的知覺組織支持的認知程度愈高，其對直屬上司的信任也會跟著增加。 三、 員工對直屬上司的信任程度增加，其採取知識分享的意願與行為也會愈高。 四、 對直屬上司的信任在員工的知覺組織支持與知識分享之間存在中介效果。 五、 高承諾人力資源措施對知覺組織支持之間的跨層次影響有顯著，個別措施中嚴格甄選、績效評估、外部競爭與內部公平薪酬制度對員工的知覺組織支持之間存在正向關係。 六、 高承諾人力資源措施對信任之間的跨層次影響不顯著，個別措施的關係皆不顯著。 七、 高承諾人力資源措施對知識分享之間的跨層次影響不顯著，個別措施中僅嚴格甄選對員工的知識分享之間存在正向關係。 依據本研究結論，提供具體建議予相關單位及後續研究者參考。 / Knowledge has the characteristics of being intangible, tacit and difficult to evaluate. So an organization can’t force its employees to actively share their own knowledge to others by using the ways of authority, command or high payment only. High Commitment Human Resource Management (HCHRM) system includes many practices which closely influence the whole company and individuals in the organization context. And in individual level, the knowledge-sharing behavior of employees may be changed by the factors of perception organization support (POS) for company and the Trust for supervisors. In this study, we use Hierarchical Linear Modeling (HLM) to investigate the relationship among HCHRM practices, POS, Trust and Knowledge Sharing (KS) in both single level and cross level. The research hypotheses all base on the theory of Social Exchange. We collected 956 valid questionnaires from the employers and employees in 27 financial companies in Taiwan. According to the results of our analysis, we found that POS and Trust in individual level were significantly and positively associated with the employees’ behavior of knowledge sharing. And Trust also had intervening effect between POS and KS. In cross-level analysis, HCHRM practices can only affect the variable of POS. Finally, we conclude with a brief discussion of the interpretations and implications of the results in the context of single-level and cross-level. We also provide some practical and reasonable suggestions for company supervisors and further research.

資訊科技的蓬勃發展，地球村世界的來臨，提供現代人快速取得知識的平台，也促成了急速轉變的全球性競爭的環境，使企業面臨了非常重大的挑戰，迫使企業開始重新思考組織核心能力，以滿足隨時可能產生變動的市場需求；企業必須作出更快速的決策，以適應全球化腳步發展。越來越多的企業警覺到知識分享對於員工累積經驗與企業正向發展的重要性，因而透過不同的方式來鼓勵員工知識分享建構具競爭力的學習型組織。 多數的研究報告皆在探討轉換型領導風格 (transformational leadership) 和交換型領導風格 (transactional leadership) 對於組織文化、組織策略執行力…等的相關性研究，尚未有探討過威權式的領導風格對於員工知識分享意願的影響。威權式的領導風格是否影響員工知識分享意願、企業具備知識分享的氛圍，是否干擾在威權式領導風格之下之員工分享知識與經驗意願 ? 有鑑於此，本研究針對威權式的領導風格如何影響員工知識分享意願，並以知識分享之企業文化為干擾因素，尋找過去相關文獻資料加以整理，歸納出假設與模型，並依照此模型進行分析與探討，以提出對實務界有效的建議與學術界未來的研究方向。 本研究採問卷調查法，在不同產業中挑選頗具盛名的公司，針對其員工進行便利抽樣，並採用Lisrel 和 SPSS軟體來進行資料的分析。從威權式領導風格、知識分享企業文化、知識分享意願三個構面，探討主管威權式的領導風格如何影響員工的知識分享意願，並以知識分享的企業文化為干擾因素。以研究結果歸納出相關結論，以提供相關建議，供實務界在推行知識管理時一個主要的關鍵成功因素，以提高知識分享的可行性。亦供學術界進行組織氛圍研究之參考。 本研究結論如下: 1. 威嚴式領導與員工知識分享意願呈現負相關。 2. 知識分享的企業文化與員工知識分享意願呈現正相關。 3. 知識分享的企業文化，干擾在威權領導風格下之員工知識分享意願程度。 / In the past, research on the knowledge-sharing behavior of indi-viduals lacked discussions on authoritarian leaderships. Therefore, this research demonstrates how authoritarian leadership and or-ganizational culture affect the knowledge-sharing behavior of indi-viduals. The purpose of this research is to focus on an authoritarian leadership’s effect on the knowledge-sharing behavior of individu-als that is influenced by innovation and a sound organizational climate. Questionnaires were administered to employees from various in-dustries in order to gather information regarding individuals’ be-havior under an authoritarian leadership. The author used conven-tional sampling methods and 233 out of 250 participants provided relevant information. The findings of the research were as follows: 1. The more a leader tends to express authoritarian leadership, the less an individual exhibits knowledge-sharing behavior. 2. The more an organization demonstrates a knowledge-sharing culture, the more an individual exhibits knowledge-sharing be-havior. Such a culture, especially, encourages ‘innovation, sharing and learning’. 3. Organizations that possess a culture that is highly oriented to-wards knowledge sharing influence the knowledge-sharing be-haviors of individuals under authoritarian leaderships.

許多企業的經理人一直在尋求有效的政策以促進員工彼此分享知識。在組織中實施激勵知識分享的政策，因為存在著許多的個人與組織的因素，兩者相互作用會影響組織的成員知識分享的行為，政策的效果很難掌握。在實務上，不同的組織激勵的政策或手段的效果，欲通過田野調查或實驗設計來評估政策所帶來效果及對組織成員行為的影響不容易實現。因此，本研究嘗試運用一項新穎的研究策略-代理人基塑模(agent-based modeling)，經由建構一個人造的世界來模擬組織成員知識分享的行為。在這個人造的社會中，研究者考慮了知識分享的報酬、組織成員的行為策略、行為策略的學習與適應機制、不同組織的群體能力水準、互動的網路、知識的選擇模式與不同的組織激勵政策設計等變數，藉以設計相關的實驗。模擬的結果產生了的幾項有趣的發現： (1) 當分享知識的報酬愈高時，代理人知識分享行為會愈多，無論是在那一種的互動網路、群體能力或分享知識的選擇模式的情況之下。(2) 代理人的互動網路是一項重要影響因素，互動網路扮演著知識流通與行為策略學習的管道，它同時會影響個體知識分享的報酬與行為策略的學習。它可能促成不分享的策略的擴散，可能會提升組織激勵的效果，也可能會增強激勵所帶來的副作用。(3) 個體的知識分享與吸收的能力如果存有差異，則能力較好的代理人將會局部地吸引能力較差的互動對象採用他的策略，即使他所用的不是可以獲致最佳報酬策略。(4) 為促進組織成員分享知識，定期審視固定獎勵的作法可以導致比較好的效果，不但可以提升分享知識的行為，也使代理人比較願意採用傾向分享知識的策略，促成組織信任的氣氛。但是，在某些情況下，可能造成反效果。(5) 最後，根據實驗的結果與研究的發現，研究者建構了一個知識分享之組織行為模型，以做為後續實證研究之參考架構。 / Mangers always look for effective policies to prompt knowledge sharing between members in an organization. It is difficult to evaluate the effect of incentive policies for stimulating knowledge sharing because there are many individual and organizational factors. In practice, it is not easy to assess the effects of different incentive policies or methods by the methods of experiment or field investigation. Therefore, a novel research strategy is applied in this study, which is called agent-based modeling. An artificial world was constructed to simulate the knowledge sharing interactions between members in an organization. This study considers some parameters including the payoff of knowledge sharing, the strategies of members, the learning and adaption mechanism of strategies, collective capabilities, interactive network, the selection methods of sharing knowledge and incentive policies to design experiments in the agent-based model. The results of simulations produced some interesting findings: (1) the higher the payoff of sharing knowledge, the more the actions of sharing knowledge is in spite of any kind of interactive networks, collective capabilities, and the selection methods of sharing knowledge. (2) Interactive Network of agents is an important factor, which plays a role of channel of knowledge transition and strategy learning. It simultaneously affects the payoff of knowledge sharing and learning of strategy. It maybe results in the diffusion of strategy of not sharing knowledge, or enhances the effect and side effect brought by incentive policies. (3) Because of difference between agents’ capabilities, agents with better capabilities will locally attract the ones with worse capabilities to learn their strategies, which even are not the best. (4) To enable sharing knowledge between members in an organization, periodic reward will get better results. It does not only increase the action of sharing knowledge, but also make agents to adop the strategies trending toward sharing knowledge. Periodic reward is helpful to form a trustful organization climate. However, in some circumstances, it may get minus effects. (5) Finally, according to experimental results and research findings, an organization behavior model of knowledge sharing has been constructed for the empirical studies in the future.

Progress towards sustainability requires changes in our individual and collective behaviour. Yet, our fundamental understanding of behaviour in relation to environmental change remains severely limited. In particular, little attention has been given to how individual and collective behaviours respond to, and are shaped by, non-linear environmental change (such as ‘regime shifts’) and its inherent uncertainties. The thesis makes two main contributions to the literature: 1) it provides one of the first accounts of human behaviour and collective action in relation to ecological regime shifts and associated uncertainties; and 2) extends the incipient behavioural common-pool resource literature that acknowledges social-ecological dynamics and ecological complexity. The overarching aim of this thesis is to further advance an empirically grounded understanding of human behaviour in social-ecological systems. In particular, the thesis attempts to unravel critical social-ecological factors and mechanisms for the sustainability of common-pool resources. This is especially relevant for contexts in which livelihoods can be more directly threatened by regime shifts. The following methods are applied: behavioural economic experiments in the lab (with students; Papers I and II) and in the field (with small-scale fishers from four different communities in the Colombian Caribbean; Paper III), and agent-based modelling empirically informed by a subset of the lab experiments (Paper IV). Paper I tests the effect of an endogenously driven regime shift on the emergence of cooperation and sustainable resource use. Paper II tests the effect of different risk levels of such a regime shift. The regime shift in both papers has negative consequences for the productivity of the shared resource. Paper III assesses the effect of different degrees of uncertainty about a climate-induced threshold in stock dynamics on the exploitation patterns; as well as the role of social and ecological local context. Paper IV explores critical individual-level factors and processes affecting the simultaneous emergence of collective action and sustainable resource use. Results cumulatively suggest that existing scientific knowledge indicating the potential for ecological regime shifts should be communicated to affected local communities, including the remaining uncertainties, as this information can encourage collective action for sustainable resource use. Results also highlight the critical role of ecological knowledge, knowledge-sharing, perceived ecological uncertainties, and the role local contexts play for sustainable outcomes. This thesis enriches the literature on social-ecological systems by demonstrating how a behavioural experimental approach can contribute new insights relevant for sustainability. Overall, these insights indicate that, given the opportunity and the willingness of people to come together, share knowledge, exchange ideas, and build trust, potential ecological crises can encourage collective action, and uncertainties can be turned into opportunities for dealing with change in constructive ways. This provides a hopeful outlook in the face of escalating environmental change and inherent uncertainties. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Manuscript.</p>

In TVET colleges, the traditional face-to-face mode of knowledge delivery appears to be the norm. Knowledge is often shared in a teaching space during a particular period of time. Students and a lecturer need to be in a specified venue during an allocated time slot for the learning process to take place which includes obtaining knowledge from the lecturer, sharing views and storing knowledge in their minds. There is often no interaction with the lecturer beyond the classroom. As such, learners with learning difficulties have no alternative platform into which they can get support; which compromises the quality of education and students’ success rate. The use of e-learning permits students to finalise a course in their own time and at their own location. It also implies that students are at an advantage as they do not need to go to a particular learning institution, and they can proceed with the training at their own pace. This research investigated how e-learning may be used as an enabler of learning by overcoming barriers associated with face-to-face learning. This was achieved through the development of a proposed e-learning framework based on the existing literature. The proposed framework was then tested through a survey distributed among TVET stakeholders to offer an improved framework. Furthermore, the improved framework was used to develop an e-learning architecture and prototype which can help guide institutions who wish to adopt e-learning. / Information Technology / M. Tech.

Knowledge has been recognized as an important resource that should be carefully managed in order to enhance organizational competitiveness. Therefore, it is important to manage knowledge resources that have been learned and stored in organizations. Several scholars in the public administration literature have examined whether public service motivation (PSM) can help employees share their knowledge in ways that contribute to the effective functioning of public organizations. However, the mechanisms by which PSM influences individuals’ propensity to share knowledge have not been clarified by past research. Against this background, at first, this study contributes to understanding the relationship between PSM and knowledge sharing by applying self-determination theory with a logical insight of the intrinsic knowledge sharing motivation process. This study also examined that relationship by testing three competing psychological mechanisms based on person-environment (P-E) fit theory: (1) person-group (P-G) fit, (2) person-job (P-J) fit, and (3) person-supervisor (P-S) fit. The research questions for this study are as follows: Do individuals with higher levels of PSM have a higher propensity toward knowledge sharing? Does the congruence between employees and their work environment increase employees’ knowledge sharing behavior? Do PSM-driven employees have higher willingness to fit in the work environment? Does P-E fit theory help explain the causal relationship between PSM and knowledge sharing? Based on primary data of 1,094 occupationally diverse employees working in 33 local governments in South Korea, the current study found that caution should be exercised when making claims regarding the effects of PSM on individuals’ propensity to share knowledge and that greater emphasis should be placed on ways public sector organizations can foster P-G fit and P-J fit. However, this study also found that the relationship between PSM and knowledge sharing is not mediated by the extent to which employees perceive that their values are congruent with those of their supervisors.
