The Ethical Implications of Population Suppression and the Irreversibility of Gene Drives
Creators: name: Kim, Joseph
Publisher: name: figshare
Year: 2019
Subjects: Genetic Engineering

description: Gene drive systems have the ability to eradicate human diseases through a gene editing technology called the CRISPR-Cas9. Malaria, which does not have any proven vaccines, is expected to affect half of the world’s population. As such, scientists are considering the eradication of malaria-carrying mosquitos which has caused much debate and controversy. The irreversible nature of gene drives, particularly population suppression, has raised ethical concerns with increased tensions between scientific innovation and the protection of Earth’s natural resources. Thus, this paper aims to examine the current situation by presenting important ethical arguments that include Chardin’s principle of irreversibility and Weiss’ beliefs on intergenerational equity, ideals upheld by the United Nations. To determine what is arguably more harmful to the ecosystem, human deaths by malaria or potentially dangerous modifications to the biosphere, remains a challenge and is expected to be an ongoing debate. Already the United States have administered field tests and Brazil is expected to legalize gene editing, therefore, it is pertinent to set appropriate regulations to minimize risks and promote safe practices in one of the most powerful scientific breakthroughs of our time.

description: Die Fluchtmigration 2015 ff. nach Deutschland hatte als einen Nebeneffekt sicherlich, dass Soziale Arbeit in der Öffentlichkeit positioniert wurde - nicht nur steigende Studierendenzahlen, sondern auch ein leer gefegter Arbeitsmarkt waren zu beobachten - bzw. sich einzelne Professionelle in diesem Bereich positionierten, etwa zu Fragen der Unterbringung von Geflüchteten. Weitere plädierten dafür, dass eine Soziale Arbeit im Kontext Flucht, die ohnehin in politische Auseinandersetzungen verstrickt sei, selber wieder politischer werden müsse. Andere verweisen auf die Geschichte der Flüchtlingssozialarbeit in Deutschland und deren Ursprünge in den Sozialen Bewegungen, weswegen es angeraten sei, sich diesen Zusammenhang wieder stärker bewusst zu machen und ggf. neue Koalitionen zu bilden. Zu diesem Nexus zwischen Sozialer Arbeit und Sozialer Bewegung gibt es allerdings aus historischer Perspektive recht wenig empirisches oder theoretisches Material, weswegen hier weitere Forschung lohnt. Der Aufsatz wirft dementsprechend ein Schlaglicht auf eine konkrete Aktionsform Sozialer Bewegungen, in der Akteure Sozialer Arbeit ebenfalls eine, z. T. gewichtige Rolle spielten: Es geht um Tribunale.
Gravitational vacuum polarization II: Energy conditions in the Boulware vacuum

Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: I show that in the Boulware vacuum (1) all standard (point-wise and averaged) energy conditions are violated throughout the exterior region---all the way from spatial infinity down to the event horizon, and (2) outside the event horizon the standard point-wise energy conditions are violated in a maximal manner: they are violated at all points and for all null/timelike vectors. (The region inside the event horizon is considerably messier, and of dubious physical relevance. Nevertheless the standard point-wise energy conditions also seem to be violated even inside the event horizon.) This is rather different from the case of the Hartle--Hawking vacuum, wherein violations of the energy conditions were confined to the region inside the unstable photon orbit. These calculations are for the quantum stress-energy tensor corresponding to a conformally-coupled massless scalar field in the Boulware vacuum. I work in the test-field limit, restrict attention to the Schwarzschild geometry, and invoke a mixture of analytical and numerical techniques. This *suggests* that general self-consistent solutions of semiclassical quantum gravity might *not* satisfy the energy conditions, and may in fact for certain quantum fields and certain quantum states violate *all* the energy conditions.

description: In der politischen Diskussion ist Populismus vor allem ein Kampfbegriff zur politischen Diffamierung, kulturellen Diskreditierung und moralischen Dämonisierung eines ideologischen Gegners, um einer inhaltlichen Auseinandersetzung ausweichen zu können. Als politische Taktik ist dies durchaus plausibel. In dieser Hinsicht soll der Begriff des Populismus als ein diskursiver Akt der Diskriminierung, der Tabuisierung und der Entmündigung von Sprechern dazu dienen, sowohl politische, als auch moralische Ausschlussmechanismen zu begründen und damit den öffentlichen Diskursraum disziplinarisch begrenzen. Die Zuschreibung Populismus beinhaltet damit zugleich eine explizite Drohung: Wer ist befugt zu sprechen und wer nicht, wer besitzt das Recht, das Wort zu ergreifen und an politischen Entscheidungsprozessen teilzuhaben? Der Autor plädiert im Umgang mit Rechtspopulismus für eine "konfliktsoziologische Perspektive".

description: Independence of the Shariah Supervisory Board One aspect of independence is the way members of the Shariah Supervisory Board are paid. Members receive remuneration from the Islamic financial institution, and there exists a potential conflict of interest whereby there is an assumption of legitimising unlawful or dubious operations to ensure that they remain on the board ie acting as a rubber stamp. Even though such assumption is not truly accurate, as board members are expected to be guided by moral belief and religious values, it still needs a proper framework in the form of policy or regulation because the credibility of Islamic financial institutions depends on the perceived independence of the board.

description: This paper explores a simple and efficient baseline for person re-identification (ReID). Person re-identification (ReID) with deep neural networks has made progress and achieved high performance in recent years. However, many state-of-the-arts methods design complex network structure and concatenate multi-branch features. In the literature, some effective training tricks are briefly appeared in several papers or source codes. This paper will collect and evaluate these effective training tricks in person ReID. By combining these tricks together, the model achieves 94.5% rank-1 and 85.9% mAP on Market1501 with only using global features. Our codes and models are available at https://github.com/michuanhaohao/reid-strong-baseline.

Microcredit, temptation spending and health outcomes in Indonesia: A longitudinal evaluation

Year: 2019
Subjects: Epidemiology

description: This dissertation examined whether or not microcredit, the provision of small loans to people usually excluded from mainstream financial institutions, demonstrably improved health for typical borrowers in Indonesia. The underlying idea behind microcredit is that loans will increase borrowers’ income and lead to positive changes in their lives, including their health. However, microcredit may actually be harmful to borrowers’ health because of stress associated with repayment obligations, extra working hours needed to start a business and tensions caused by shifting power dynamics in the household. Moreover, for some borrowers, a loan may facilitate increased spending on so-called temptation goods that are damaging to health, such as tobacco and processed foods. Previous research has not adequately explored these competing positive and negative pathways linking microcredit and health.
      The project consisted of three parts: a systematic review and two empirical papers. The systematic review synthesized the scientific literature related to individual microcredit loans, health-related temptation spending, psychological stress and self-reported health outcomes in adults. The empirical papers estimated the causal effect of microcredit on household expenditures on tobacco and processed foods, and individual psychological distress and self-rated health. Both empirical papers used data from the Indonesia Family Life Survey, a longitudinal study that followed more than 7,000 households over 21 years.
      After adjusting for confounding, people living in borrowing households had levels of psychological distress and self-rated health that were similar to people living in non-borrowing households. These predominantly null findings were relatively robust across multiple models. Microcredit households did spend substantially more money on tobacco than non-borrowers. This difference was driven by households with male borrowers. Still, tobacco spending ultimately did not affect health outcomes. Based on empirical evidence from this dissertation along with findings from other studies, policymakers and practitioners should recalibrate their high expectations of microcredit as a socially transformative intervention. At the same time, fears about the unintended health consequences of microcredit may have been exaggerated. Reliance on longitudinal data generated insights into microcredit and health that could not be established from randomized controlled trials.

description: We define a statistical ensemble of non-degenerate graphs, i.e. graphs without multiple- and self-connections between nodes. The node degree distribution is arbitrary, but the nodes are assumed to be uncorrelated. This completes our earlier publication \cite{bck}, where trees and degenerate graphs were considered. An efficient algorithm generating non-degenerate graphs is constructed. The corresponding computer code is available on request. Finite-size effects in scale-free graphs, i.e. those where the tail of the degree distribution falls like $n^{-β}$, are carefully studied. We find that in the absence of dynamical internode correlations the degree distribution is cut at a degree value scaling like $N^γ$, with $γ= \min[1/2, 1/(β-1)]$, where $N$ is the total number of nodes. The consequence is that, independently of any specific model, the inter-node correlations seem to be a necessary ingredient of the physics of scale-free networks observed in nature.

description: Fieldwork revealed evidence of sporadic occupation dating from the medieval period to the present. Although prehistoric flintwork was recovered, the earliest excavated feature was a ditch of probable early medieval date which suggests attempts to drain the open marshland of the estuarine floodplain of the River Adur. Subsequently, washed salts and sands deriving from medieval salt manufacture were deposited, forming a saltern mound used intermittently from the thirteenth into the sixteenth century. The mound showed evidence of sporadic flooding until the mid-sixteenth-century. A saw pit was in operation by the early-nineteenth century, possibly in connection with a wharf known from documentary sources.

German Essay.On the primal division of making history and writing history. The redeeming function of practice and theory, contingency and teleology, the dead and the active strata of law ensure the open yet progression-friendly horizon of universal history. The Marxist mythology of the "proletariat" being at once the chosen ones of political history, and the agency to write its own history, leads to self-destructive contradiction not only in practice, also in theory.
As this is an essay in honor of a very learned teacher and friend, The Marxist scholar on the history of technology and economy, Wolfgang Pircher, it has a playful, "scholastic" edge to it.

Microdynamics of War-to-Peace Transitions: Evidence from Burundi
Creators: Samii, Cyrus
Publisher: name: Columbia University
Year: 2011
Subjects: subject: Political science
subject: FOS: Political science

description: In these three essays, I study important facets of the transition to peace after Burundi's 1993-2005 civil war. The first essay studies the effects of quota-based ethnic integration within Burundi's army on expressions of prejudice and ethnic salience among soldiers. Exploiting a natural experiment within the army, I find that exposure to quota-based integration reduced prejudice and had no effect on ethnic salience, countering a prevailing view in the literature that quota-based integration is likely to exacerbate ethnic tensions. The second essay studies individuals' preferences over transitional justice alternatives. I find that support for punishment and truth-seeking is more tepid than the advocacy literature has suggested, that ethno-political motivations seem to dominate expressed preferences for punishment and truth-seeking, and, using a persuasion experiment, that simple forms of deliberation may actually polarize people. The third essay, co-authored with Michael Gilligan and Eric Mvukiyehe, examines the impact of Burundi's ex-combatant reintegration program on the economic and political reintegration of demobilized rebels. Exploiting another natural experiment, we find that the program provided substantial economic benefits, but that these economic benefits did not seem to contribute to political integration, at least in the short-run. The essays enrich our understanding of Burundi's difficult transition to peace. They also essays just how one may bring high scientific standards to study policies in the otherwise challenging context of post-conflict transitions.

description: Building on a pair of earlier papers, I investigate the various point-wise and averaged energy conditions for the quantum stress-energy tensor corresponding to a conformally-coupled massless scalar field in the in the (1+1)-dimensional Schwarzschild spacetime. Because the stress-energy tensors are analytically known, I can get exact results for the Hartle--Hawking, Boulware, and Unruh vacua. This exactly solvable model serves as a useful sanity check on my (3+1)-dimensional investigations wherein I had to resort to a mixture of analytic approximations and numerical techniques. Key results in (1+1) dimensions are: (1) NEC is satisfied outside the event horizon for the Hartle--Hawking vacuum, and violated for the Boulware and Unruh vacua. (2) DEC is violated everywhere in the spacetime (for any quantum state, not just the standard vacuum states).

description: We consider the problem of minimizing the eigenvalues of the Schrödinger operator $H=-Δ+αF(\ka)$ ($α>0$) on a compact $n-$manifold subject to the restriction that $\ka$ has a given fixed average $\ka_{0}$. In the one-dimensional case our results imply in particular that for $F(\ka)=\ka^{2}$ the constant potential fails to minimize the principal eigenvalue for $α>α_{c}=μ_{1}/(4\ka_{0}^{2})$, where $μ_{1}$ is the first nonzero eigenvalue of $-Δ$. This complements a result by Exner, Harrell and Loss (math-ph/9901022), showing that the critical value where the circle stops being a minimizer for a class of Schrödinger operators penalized by curvature is given by $α_{c}$. Furthermore, we show that the value of $μ_{1}/4$ remains the infimum for all $α>α_{c}$. Using these results, we obtain a sharp lower bound for the principal eigenvalue for a general potential. In higher dimensions we prove a (weak) local version of these results for a general class of potentials $F(\ka)$, and then show that globally the infimum for the first and also for higher eigenvalues is actually given by the corresponding eigenvalues of the Laplace-Beltrami operator and is never attained.

description: T helper 17 (Th17) cells play important role in the defense against pathogens and autoimmune diseases. Many cytokines can induce Th17 cell differentiation. However, the mechanism of Th17 cell differentiation is not well clarified. RankL, a member of the TNF superfamily, binds with Rank and then participates in the proliferation and differentiation of many kinds of cells. Recent studies showed that RankL-Rank signaling is closely related to Th17 differentiation and function. The detail of the Rank-RankL pathway in Th17 cell differentiation is still unclear. To illustrate the role of Rank-RankL in Th17 differentiation, naive CD4 + T cells were differentiated into Th17 cells with or without RankL stimulation. During Th17 differentiation, the expression of Rank obviously increased. The RankL stimulation significantly increased Th17 cell differentiation indicated by increased IL-17-positive cell number, highly expressed IL-17 and IL-22 and elevated IL-17 secretion. These effects were canceled by Rank-Fc addition. In further study, RankL treatment during Th17 differentiation up-regulated Fas expression. Fas knockdown inhibited the Th17 differentiation promoted by RankL. In this study, it was confirmed that Rank-RankL signaling could promote Th17 cell differentiation through Fas induction.
Inco Limited : one hundred years of operation : where do we go from here?
Creators: name: Napier, William A.
Publisher: name: The University of British Columbia
Year: 2009

description: Inco is celebrating a 100 years of operations. One of the environmental areas we have worked hard at is reclamation and rehabilitation. For example in 1916 Inco's predecessor company, Canadian Copper Company, established its Agricultural Department as a first attempt of reclaiming mining and roasting areas. In keeping with societal changes reclamation concepts, designs, objectives and expectations have changed with each passing decade. This paper highlights some of these milestones. This paper provides a brief review of how the mining industry and, in particular, Inco has managed the evolutionary changes in mine rehabilitation. The paper describes how reclamation planning has become an integrated feature of a Project's economic feasibility study, how progressive reclamation has been incorporated at mining operations and how mine closure techniques are employed and advanced globally. This paper touches on some of the current issues facing a company's reclamation effort. Rationalizing a mine closure in the context of sustainable development is just one of a series of challenges currently being addressed by the mining community. A perspective is provided on other topics such as assessing closure finality i.e. is there ever a truly walk away situation; addressing future technological advances in the wake of current operating practices, and securing financial assurance. The importance of risk management is also discussed. Finally the paper speculates on how reclamation affect constituents can help chart a path forward as Inco enters its second century.

This was found using contact-resistance atomic force microscopy on carbon black/polymer composites. The features in the current images, when presented as a function of the cut-off current, or as a function of the total area covered by the electrically connected objects, appear to obey a cluster statistics that is similar to the one predicted and observed in continuum percolation systems.

description: By undertaking an in-depth case study in Yi County where the first microfinance program was launched in 1993, this dissertation investigates how microfinance was adopted and adapted in China through four chronologically established microfinance programs: microfinance NGOs, microfinance programs housed within national subsidized poverty alleviation loans, rural credit cooperatives microfinance programs, and commercial microfinance companies. Inspired by but distinct from the policy mobilities approach, this dissertation takes upon the notion of assemblage as the analytical framework under which the adoption and adaptation process can be conceived as four distinct, though overlapping assemblages that are constantly fluctuating and in (re)formation. The questions asked, therefore, are how these assemblages are constituted by heterogeneous elements, including policies, institutions, discourses, and practitioners? What are the attendant contradictions and externalities and how are they managed (or fail to be managed)? And what are the politically progressive and regressive possibilities that arise in the process? By illustrating how four microfinance assemblages in Yi County were produced, maintained, transformed and/or deteriorated, this dissertation focuses on the messy and complex processes of microfinance formations and reveals the not-always-coherent and sometimes even contradictory capacities of the elements common to all microfinance assemblages and the practices required to draw these elements together, forge connections between them, and sustain these connections it the face of such capacities.

description: More than 168 million children work worldwide. While some types of work are beneficial for children, some types are detrimental for children's health, growth, education and future well-being. The theory defines poverty and lack of access to credit as main causes of child work. While there is no one-to-one replacement, work reduces the amount of education received by child workers as it competes for children's time. This mix-method dissertation explores child work in two studies: 1) a qualitative study of child work in Tajikistan and 2) a quantitative study of microfinance participation and its effect on global child work and education.
      The qualitative study of the child work is analyzed through narratives of child workers and their parents in Tajikistan. This study examined the pathways to child work and the families' understanding of child work experiences. Furthermore, the factors causing the increase of child work prevalence in the country and the consequences of children's involvement in the labor market were explored. The children and parent's narratives revealed several common themes. First, the families resort to child work due to financial need. Second, less explored and unconventional perspectives on child work were recorded. Children and parents describe employment as means to become independent and gain respect and status. Moreover, they list becoming socialized and prepared to adult life from early stages of life as a value added to labor market engagement. Child work was also described as means to stay physically healthy and as a protective factor from risk-taking behaviors.
      The quantitative analysis of this dissertation explores the topic through a broader perspective. The study evaluates the impact of microfinance programs on child economic activity and education globally, using macro data for 113 countries of the world for the period of 15 years (1995-2010). The results of the study suggest that there is a positive association between microfinance and secondary school enrollment. The relationship between microfinance and primary school enrollment, as well as primary school completion is ambiguous. No statistically significant relationship between microfinance and child work was found. Future research directions and implications for policy are examined.

description: The magnitude of anisotropic flow in a nucleus-nucleus collision is determined by the energy density field, $ρ(x,y,z)$, created right after the collision occurs. Specifically, elliptic flow, $v_2$, and triangular flow, $v_3$, are proportional to the anisotropy coefficients $\varepsilon_2$ and $\varepsilon_3$, which are functionals of $ρ$. We express the mean and the variance of $\varepsilon_2$ and $\varepsilon_3$ as a function of the 1- and 2-point functions of $ρ$. These results generalize results obtained previously, that were valid only for central collisions, or only for identical point-like sources. We apply them to the color glass condensate effective theory, using the recently derived expression of the 2-point function.

Dwells in the Far East (Kamchatka, Kuril Islands, Primorsky Krai) (Medvedev, 1987; Medvedev et al., 1991), hosts are Siberian bat and Ikonnikov’s bat.
 It should be noted that, despite the considerable length, Siberia and the Far East complex is characterised by the uniformity of the ectoparasite fauna. The only exception — flea I. ussuriensis is found only in the Far East. Perhaps the species is more widespread, and the lack of finds in Western and Eastern Siberia is due to insufficient knowledge of the area.

description: In February and March 1977, an area west of Steyning parish church was excavated prior to redevelopment. Previous excavations in 1962-3 and 1967-8 to the south and south-west of the church produced evidence for late Saxon and medieval occupation, and it was suggested that the late Saxon town was centred on the church. The 1977 excavation revealed no structures of the late Saxon or medieval periods, but there was evidence of occupation and industrial activitiy in the vicinity.
Microfluidic Selection and Applications of Aptamers

description: BioMEMS technology has the potential to increase the efficiency of conventional biological and medical protocols, by reducing their consumption of time and resources. Through more efficient surface-based chemical reactions and automation of tedious manual processes, orders of magnitude increases in efficiency across a number of metrics can be achieved by shifting conventional medical and biological protocols to the microscale domain. The SELEX process, by which aptamer sequences are selected via isolation from randomized libraries, is a time-consuming and resource-intensive protocol which is being performed with increasing frequency in both academic and private sector laboratories. Conventional approaches using macroscale technology cannot meet the current demand for selection of new aptamer sequences, as they require months of work and liters of expensive reagents. Microscale approaches to the SELEX process have been receiving attention in recent years due to their initial successes in reducing the time and reagents necessary to find aptamers. In particular, microscale "selection" or partitioning of weakly bound sequences from aptamer candidates, and on-chip integration of the protocol have separately been explored as approaches to scaling and improving SELEX. Initial results have shown that this technology can reduce resource requirements for SELEX by at least an order of magnitude. In this dissertation, a new approach to on-chip SELEX is developed which integrates highly efficient microfluidic selection and on-chip integration of the entire protocol. As a result, further reductions in processing time and reagent requirements can be realized. A demonstration of aptamer capabilities is first achieved via the development of a microfluidic aptasensor for cocaine, which utilizes aptamer-coated microbeads and fluorescent detection. Secondly, a technology necessary for on-chip integration of SELEX is developed: a novel bead-based polymerase chain reaction (PCR) protocol which vastly simplifies procedures for the capture and resuspension of ssDNA in solution. This protocol is then integrated on-chip with bead-based partitioning of weakly bound sequences to develop a microchip which performs temperature-specific isolation of aptamer sequences from a randomized library. Finally, this approach is further developed into a microfluidic SELEX chip which is capable of performing multiple rounds of temperature-specific SELEX. The novel bead-based protocol is shown to efficiently isolate target-binding sequences from a random library in a fraction of the time previously reported. As a result, this research provides a schematic for the development of highly efficient, integrated microfluidic SELEX devices. Such devices have the potential to impact a variety of fields including medical diagnostics, drug detection, and aptamer-based therapeutics.

description: This project explores the historical landholdings of the Bennehan and Cameron families in Durham, North Carolina, and their evolution over time. The project focuses on mapping the plantations owned by these families along the Flat, Little, Eno, and Neuse Rivers. Using QGIS, shapefiles and associated metadata were generated to create a detailed digital map of the region. The data was then imported into Mapbox and supplemented with a timeline slider to illustrate the changes in land ownership and boundaries over the 18th and 19th centuries. This tool enables users to navigate the historical transformations of these plantations, offering insights into the lives of the free and enslaved people who lived and worked on the land.

description: In these lectures three different methods of computing the asymptotic expansion of a Hermitian matrix integral is presented. The first one is a combinatorial method using Feynman diagrams. This leads us to the generating function of the reciprocal of the order of the automorphism group of a tiling of a Riemann surface. The second method is based on the classical analysis of orthogonal polynomials. A rigorous asymptotic method is established, and a special case of the matrix integral is computed in terms of the Riemann $ζ$-function. The third method is derived from a formula for the $τ$-function solution to the KP equations. This method leads us to a new class of solutions of the KP equations that are \emph{transcendental}, in the sense that they cannot be obtained by the celebrated Krichever construction and its generalizations based on algebraic geometry of vector bundles on Riemann surfaces. In each case a mathematically rigorous way of dealing with asymptotic series in an infinite number of variables is established.
