Bunge’s Mathematical Structuralism Is Not a Fiction
In this paper, I explore Bunge’s fictionism in philosophy of mathematics. After an overview of Bunge’s views, in particular his mathematical structuralism, I argue that the comparison between mathematical objects and fictions ultimately fails. I then sketch a different ontology for mathematics, based on Thomasson’s metaphysical work. I conclude that mathematics deserves its own ontology, and that, in the end, much work remains to be done to clarify the various forms of dependence that are involved in mathematical knowledge, in particular its dependence on mental/brain states and material objects
Admissibility in Federal Courts of Evidence Wrongfully Obtained by Persons Other Than Federal Officers or by Cooperation Between Such Persons and Federal Officers
It is a firmly established rule in the federal courts, that evidence obtained by an illegal search and seizure, within the purview of the Fourth Amendment to the Constitution of the United States, is not admissible providing timely steps are taken for its exclusion or return. However, that rule is limited in its application to federal officers or agents, so that quite generally it may be said, that evidence obtained by private,mdividuals or municipal or state officers, acting as such, is admissible in federal courts, regardless of the manner in which it is obtained
Exploring the Relationship Between Depression and Resilience in Survivors of Childhood Trauma
Although experiences of trauma are common, reactions vary due to a host of biopsychosocial and cultural factors that influence the individual reaction to the trauma (Nakai et al., 2015). One such factor is resiliency, the capability to adapt in adverse environmental circumstances (Basim & Cetin, 2011). This study used hierarchical multiple regression to examine the relationships between childhood trauma, recent experiences of depression, and resilience in adult university students. This study also examined the possible moderating effects on depression by resilience. Participants completed the Childhood Trauma Questionnaire, Connor-Davidson Resilience scale, and PROMIS Depression survey. Small significant relationships were found for several of the variables, including: childhood trauma and ethnicity, childhood trauma and age, childhood trauma and income, childhood trauma and education, childhood trauma and resilience, childhood trauma and depression, depression and ethnicity, depression and education, depression and income, resilience and gender, resilience and income, and resilience and trauma. The results of this study also suggest resilience has a moderate inverse relationship with depression. The data also confirmed the existing literature which noted that adults who have experienced trauma in childhood have significantly higher rates of depression in adulthood than adults who have not experienced trauma

Design and fabrication of a low-specific-weight parabolic dish solar concentrator
A segmented design and fabrication and assembly techniques were developed for a 1.8 m (6 ft) diameter parabolic concentrator for space application. This design and these techniques were adaptable to a low cost, mass-produced concentrator. Minimal machining was required. Concentrator segments of formed magnesium were used. The concentrator weighed only 1.6 kg sq m (0.32 lbm/sq ft)

A Knowledge Compilation Map
We propose a perspective on knowledge compilation which calls for analyzing
different compilation approaches according to two key dimensions: the
succinctness of the target compilation language, and the class of queries and
transformations that the language supports in polytime. We then provide a
knowledge compilation map, which analyzes a large number of existing target
compilation languages according to their succinctness and their polytime
transformations and queries. We argue that such analysis is necessary for
placing new compilation approaches within the context of existing ones. We also
go beyond classical, flat target compilation languages based on CNF and DNF,
and consider a richer, nested class based on directed acyclic graphs (such as
OBDDs), which we show to include a relatively large number of target
compilation languages
Teaching Creativity Across Disciplines at Ontario Universities
While a wide variety of publications have suggested that the development of student creativity should be an important objective for contemporary universities, information about how best to achieve this goal across a range of disciplinary contexts is nonetheless scant. The present study aimed to begin to fill this gap by gathering data (via an electronic survey instrument) about how the teaching and learning of creativity are perceived and enacted by instructors in different disciplines at Ontario universities. Results indicated points of both convergence and divergence between respondents from different fields in terms of their understandings of the place of creativity within courses and programs, and in terms of strategies they reported using to enable creativity in their students. We discuss the implications of these findings, including the ways in which the data speak to ongoing debates about the role of disciplines within teaching, learning, and creativity more broadly.
Bien qu’une grande diversité de publications suggère que le développement de la créativité chez l’étudiant devrait être un objectif important pour les universités contemporaines, l’information quant à la meilleure façon d’atteindre un tel objectif parmi tout un éventail de contextes disciplinaires demeure insuffisante. La présente étude vise à commencer à combler cet écart en rassemblant des données relatives aux façons dont l’enseignement et l’apprentissage de la créativité sont perçus et mis en œuvre par les instructeurs de diverses disciplines auprès des universités de l’Ontario. Les résultats ont indiqué à la fois des points de convergence et de divergence entre les répondants provenant de secteurs différents en ce qui a trait à leur compréhension de la place de la créativité dans les cours et les programmes, et en ce qui a trait aux stratégies qu’ils déclarent utiliser pour susciter la créativité chez leurs étudiants. Nous discutons des implications de ces résultats, y compris de la façon dont les données se révèlent aux débats actuels qui portent sur le rôle des disciplines et, de façon plus générale, sur l’enseignement, l’apprentissage et la créativité
Assessing the Effect of Differential Diffusion for Stratified Lean Premixed Turbulent Flames with the Use of LES-PDF Framework
Lean premixed stratified combustion is rapidly growing in importance for modern engine designs. This paper presents large eddy simulations for a new burner design to assess the predictive capability of the probability density function (pdf) approach to flames that propagate through non-homogeneous mixtures in terms of equivalence ratio. Although various efforts have been made in the past for the simulation of the same test case the novelty of this work lies to the fact that it is the first simulation effort that differential diffusion is accounted for given the relatively low Reynolds numbers (13,800) of the configuration. First mean and root mean square velocity simulations are performed for the isothermal cases to assess the effect of the grid resolution and the overall LES flow field solver. Then instantaneous snapshots of the flame are presented to provide insight to the structure of the flame and the effect of stratification. Finally, results for velocities, temperature and mixture fraction are presented and compared with the experimental data. Overall, the results are in very good agreement with experiments
