A new problem of evil: authority and the duty of interference

The traditional problem of evil sets theists the task of reconciling two things: God and evil. I argue that theists face the more difficult task of reconciling God and evils that God is specially obligated to prevent. Because of His authority, God's obligation to curtail evil goes far beyond our Samaritan duty to prevent evil when doing so isn't overly hard. Authorities owe their subjects a positive obligation to prevent certain evils; we have a right against our authorities that they protect us. God's apparent mistake is not merely the impersonal wrong of failing to do enough good — though it is that too. It is the highly personal wrong of failing to live up to a moral requirement that comes bundled with authority over persons. To make my argument, I use the resources of political philosophy and defend a novel change to the orthodox account of authorit

Quantum frecuency conversion for hybrid quantum networks

The ability to control the optical frequency of quantum state carriers (i.e. photons) is an important functionality for future quantum networks. It allows all matter quantum systems - nodes of the network - to be compatible with the telecommunication C-band, therefore enabling long distance fiber quantum communication between them. It also allows dissimilar nodes to be connected with each other, thus resulting in heterogeneous networks that can take advantage of the different capabilities offered by the diversity of its constituents. Quantum memories are one of the building blocks of a quantum network, enabling the storage of quantum states of light and the entanglement distribution over long distances. In our group, two different types of memories are investigated: a cold atomic ensemble and an ion-doped crystal. In this thesis I investigate the quantum frequency conversion of narrow-band photons, emitted or absorbed by optical quantum memories, with two different objectives: the first one is to connect quantum memories emitting or absorbing visible single photons with the telecommunication wavelengths, where fiber transmission loss is minimum. The second and main goal is to study the compatibility between disparate quantum nodes, emitting or absorbing photons at different wavelengths. More precisely the objective is to achieve a quantum connection between the two optical memories studied using quantum frequency conversion techniques. The main core of this work is the quantum frequency conversion interface that bridges the gap between the cold ensemble of Rubidium atoms, emitting photons at 780nm, and the Praseodymium ion doped crystal, absorbing photons at 606nm. This interface is composed of two different frequency conversion devices, where a cascaded conversions takes place: the first one converts 780nm photons to the telecommunication C-band, and the second one converts them back to visible, at 606nm. This comes with several challenges such as conversion efficiency, phase stability and parasitic noise reduction, which are important considerations to show the conservation of quantum behaviors through the conversion process. This work can be divided in three parts. In a first one, we built a quantum frequency conversion interface between 606nm and the C-band wavelength, capable of both up and down-conversion of single photon level light. We also characterized the noise processes involved in this specific conversion. In the down-conversion case we showed that memory compatible heralded single photons emitted from a photon pair source preserve their non-classical properties through the conversion process. In the up-conversion case, we showed the storage of converted telecom photons in the praseodymium doped crystal, and their retrieval with high signal to noise ratio. The second part of the work was devoted to the conversion of photons from an emissive Rubidium atomic quantum memory to the telecom C band. In this work we converted the heralding photons from the atomic ensemble and measured non-classical correlations between a stored excitation and a C-band photon, necessary for quantum repeater applications. In the last part of the thesis, we setup the full frequency conversion interface and showed that heralded photons emitted by the atomic ensemble are converted, stored in the solid state memory and retrieved with high signal to noise ratio. We demonstrated that a single collective excitation stored in the atomic ensemble is transfered to the crystal by mean of a single photon at telecom wavelength. We also showed time-bin qubit transfer between the two quantum memories. This work represents the first proof of principle of a photonic quantum connection between disparate quantum memory nodes. The results presented in this thesis pave the way towards the realization of modular and hybrid quantum networks.Postprint (published version

Strategy of Resistance Under the Guise Of Collaboration: An Anthropological View on Case of Forest Tenure. The implementation of the projects on the state forest area provides collaboration between the local community and the government. Although, the first step and during the process, the local community effort to control the forest area through tactic to select the seed of the tree, reveal the location of the project, and get the certificate of the forest land. The situation show a collaboration contained strategy of resistance from the community to respond the authority of the government. The analysis inspire qualitative research approach and theory of resistance. Theoretically, the result of the analysis show a dynamic pattern of community's resistance. The result change the old views of the community's resistance which has been defined anonimously, hiddenly, quietly, and secretly. The phenomenon construct new discussion about dynamic relation of power. Practically, the result of the analysis underline the urgency of the forest development approach which respect and recognize the local community rights

Toward a ritual poetics : dream of the Rood as a case study

The notion of “ritual poetics” explored in this essay weds the findings of John Miles Foley’s immanent art to ritual theories of signification in order to show that some features of early medieval verse may carry a metonymic force linking the spoken or oral-related written word to the vivid, multilayered experience of ritualized situations. The hypothesis that ritual features, when integrated into oral-related poems, preserve their association with lived, emergent ritual processes is examined through close analysis of _Dream of the Rood_

Oral traditional approaches to Old English verse

Since the publication of Francis P. Magoun's (1953) seminal article on the formula in Anglo-Saxon narrative verse, oral traditional approaches in the field of Old English have undergone a number of transitions, in the process growing more sophisticated and varied in technique and application.Not

Conflict transformation and collaboration in developing social forestry in Flores, Indonesia

Social movements to realize forest tenure reforms have been ongoing since the 1970s, particularly through policies under the broad umbrella of social forestry. In Indonesia, social forestry programs  are initiated by the government, communities, NGOs, academics, companies, and donors, and are based on specific socio-economic and ecological interests. Weak synergies, however between programmatic implementation and stakeholder interests, triggers various forest tenure conflicts. The research examines the complexity of these conflicts, namely focusing around the approaches to conflict transformation that can lead to collaboration in realizing forest sustainability that also support interests of people living in and around forests. I employed  a qualitative approach by   collecting data through  in-depth interviews and participatory observations in Flores in 2017 and 2020. The results show that forest tenure conflicts have occurred since the 1970s due to state forest territorialization. Conflicts culminated in the determination of state forest area boundaries through the 1984 state program entitled the “consensus-based forest land use planning” initiative. Until 2008, efforts to resolve conflicts by offering the community access rights through  community forestry programs   initiated by the government were rejected by NGOs and the local community.  NGOs facilitated communities to  demand the return of state forest land as  customary forest. This conflict presented the opportunity to facilitate multi-stakeholder forestry programs through a conflict transformation approach by building long-term stakeholder collaboration. Since 2010, the collaboration between stakeholders  took place through the community forest  program. This study shows  the need for more direct attention to studying conflict resolution under an integrated and long-term approach to conflict transformation and collaboration. Pragmatically,  this study shows the importance of integrated social forestry policies that synergize various schemes initiated by stakeholders to realize forest sustainability and support local community interests

Culture of Control Versus the Culture of Resistance in the Case of Control of Forest

The implementation of rights, policy, forest official, and repressive approach by the government shows that the culture of control is applied at forest tenure. This research showed that the application of cultural control by the Government clashed with the interests of local wisdom and socio-economic communities around the forest. The local community have developed strategies and tactics to resist the Government through controlling the land, determining the types of plant, and by implementing community-based forest management system. These resistance strategies and tactics is the manifestation of the socio-economic conditions which are integrated in the community culture. Through the perspective of power (Foucault) and resistance (Scott), this research shows the urgency to put culture and behavior as the focus of an analysis particularly in the midst of a strong influential political ecology perspective. The focus on culture and behavior means that an analysis on controlling culture is not only to discuss the strategy of fulfilling the formal rights of the government, but also to discuss the arrogant, repressive and proud behavior of the government of its authority and power. Equally, the analysis of the culture of resistance does not only discuss the strategy to get the formal rights of the community, but also deliberate on the behavior of the community to implement their strategy quietly, secretly, and • while avoiding the forest staff
