An Analysis of Variation Between Cores For Intel Xeon Phi Knights Corner And Xeon Phi Knights Landing
As we move towards exascale computing, the efficiency of application performance and energy utilization, must be optimized by redefining architectural features and application performance analysis. This research analyzes the performance per core of 8 applications on Intel Xeon Phi Knights Corner (KNC) and Knights Landing (KNL) to determine if performance variation within cores can lead to performance and energy improvements. Our results showed that KNC architecture\u27s core vary in performance, leading to faster inner core performance as a result of memory characteristics and core utilization. It also shows that cores 17, 34, and 51 on the KNL architectures performs consistently slower than other cores, with core 0 performing either faster, slower or within the average performance time all the cores. A power performance study was then done utilizing different core configurations on the KNC. The results show that by targeting inner cores for applications that exhibit better inner core performance, a maximum energy reduction of 16.4% compared to a con- figuration using all cores was possible with its optimal thread configuration. Energy reduction was achieved with along with a 2% reduction in the fastest execution time of the same application. Our results also show how application characteristics lead to different core variation performances on KNC and KNL Xeon Phi architectures

The Crusade of Transitional Justice Tracing the Journeys of Hegemonic Claims
Engaging with Third World Approaches to International Law (TWAIL), this paper reviews the crusade of transitional justice by tracing the journeys of problematic claims across the world. Building on original empirical material, I document the dissemination of specific set of claims as well as their hegemonic functions through a systematic review of the transitional justice provisions contained in all peace agreements signed since 1990. I centre on the epistemic violence perpetuated through such normative crusade. The crusade and limitation of disseminated claims neglect the inevitable arguments about the past, frictions between legal ‘global standards,’ the resulting technocratic practices and the often-silenced politicised negotiations taking place through transitional justice practices. Gradually, the consolidation of hegemonic approaches took over institutional debates addressing legacies of mass violence and, consequently, silencing certain types of violence. In other words, I argue that transitional justice is simultaneously: 1) an increasingly normative and technocratic field that claims to deal with legacies of violent pasts for democratic futures, 2) a set of processes that silences normative and discursive battles about a violent past and perpetuates epistemic violence

Victims' Inclusion and Transitional Justice: Attending to the Exclusivity of Inclusion Politics (PSRP Research Report)
This report reviews efforts to include victims in transitional justice programmes, and the difficulties of managing the politics of inclusion in the transitional justice setting. It draws on empirical data from peace agreements and fieldwork in Burundi to scrutinize how inclusion is provided for in peace agreements on paper, and in post-agreement practice. The report argues that 'victimhood' and 'inclusion' are concepts that lack conceptual clarity. In practice, inclusion efforts are often pursued without consideration for the political and socio-cultural dynamics that emerge with any attempt to design an inclusive transitional justice process. Intervening to ensure inclusivity involves entering webs of power dynamics between individuals who have fluid political and social identities
Tavelure - Réduire ses traitements
«Bien positionner ses traitements au printemps est la clé pour maîtriser la tavelure avec un minimum de phyto », introduit Laurent Jamar, chercheur belge. Il est vrai que, pour pouvoir contaminer une feuille, une fleur ou un fruit, le champignon responsable de la tavelure a besoin de la présence d’un film d’eau pendant un certain laps de temps, variable selon la température : la protection phytosanitaire doit ainsi être ajustée aux conditions pédoclimatiques, définies si possible au niveau du verger. « Pour cela, deux outils sont essentiels : une station météo, qui enregistre les données localement heure par heure, et un modèle de simulation des infections, qui analyse les données météos enregistrées. Assurer une protection vis-à -vis des contaminations primaires évite ainsi toute intervention pendant l’été ! », poursuit le chercheur
Impact of Integrated Science and English Language Arts Literacy Supplemental Instructional Intervention on Science Academic Achievement of Elementary Students
The purpose of this quasi-experimental, nonequivalent pretest-posttest control group design study was to determine if any differences existed in upper elementary school students’ science academic achievement when instructed using an 8-week integrated science and English language arts literacy supplemental instructional intervention in conjunction with traditional science classroom instruction as compared to when instructed using solely traditional science classroom instruction. The targeted sample population consisted of fourth-grade students enrolled in a public elementary school located in the southeastern region of the United States. The convenience sample size consisted of 115 fourth-grade students enrolled in science classes. The pretest and posttest academic achievement data collected consisted of the science segment from the Spring 2015, and Spring 2016 state standardized assessments. Pretest and posttest academic achievement data were analyzed using an ANCOVA statistical procedure to test for differences, and the researcher reported the results of the statistical analysis. The results of the study show no significant difference in science academic achievement between treatment and control groups. An interpretation of the results and recommendations for future research were provided by the researcher upon completion of the statistical analysi
Black middle-class neighborhoods in Louisville through multiple lenses.
This dissertation is an articles-based, mixed methods study that analyzes Black middle-class neighborhood attainment in Louisville. Racialized social structure theory is the theoretical framework that is employed to make sense of the adverse positionality of Black middle-class neighborhoods. Racialized social structure theory posits that individuals are placed in racial categories that are hierarchically arranged, which, at the neighborhood level, translates to White and Black householders advancing their material interests in competing ways. These competing interests are asymmetrical in terms of power relations, which means that the neighborhood choices of the Black middle-class are constrained by the routinized ways that the racialized social structure diminishes their claims to middle-class status. The first and second articles primarily utilize the 2016 American Community Survey to compare Black middle-class neighborhood attainment across similarly sized urban areas and to analyze the spatial proximity of Black middle-class households and households considered poor, respectively. These articles find that the segregation levels faced by the Black middle class affect how many Black middle-class households live in prototypical middle-class neighborhoods and show that durable geographical patterns are interwoven with the racial characterizations of neighborhoods, both yielding disadvantages to neighborhoods with growing Black populations. In the third article, the perspectives of middle-class Blacks are brought to the forefront and uncover that a great deal of ownership is expressed by respondents in terms of the home buying process and their neighborhood lives and a relationship is found between familial class background and neighborhood preferences. Overall, Black middle-class neighborhoods in Louisville are socioeconomically heterogeneous. However, this heterogeneity reflects neighborhood choices that are constrained by trade-offs between living in neighborhoods conducive to wealth-building or living in neighborhoods that are less economically advantaged, but allow for more social comfort
A Social Justice Perspective on the Role of Copyright in Realizing International Human Rights
Moderator: Michael Mireles, Associate Professor of Law, University of the Pacific, McGeorge School of Law
This panel will examine the impact of human rights norms on substantive intellectual property law. The focus of the panel is whether intellectual property law is adequately flexible to provide access to knowledge, in the form of primary and secondary materials as well as scientific materials, access to medicines, and access to food, such as seeds. The panel will further explore whether any flexibilities incorporated into intellectual property law harm the incentives provided by that law, including an analysis of parallel importation
