Constructive skepticism, critical thinking and the ethics of belief
Creators: name: Rebman, John L.
Publisher: name: University of British Columbia
Year: 2009

description: One of the primary aims of education is to enable students to secure reliable standards and procedures by which they can acquire beliefs that are, if not true, at least likely to be true. The questions of belief acquisition and the manner in which those beliefs are held, although epistemic, are also distinctively ethical. Implicit within epistemological concepts such as truth, justification and objectivity are ethical concerns such as honesty, integrity and responsibility. In response to the question “What ought I to believe?”, any serious critical thinker must examine the reasons for holding (or not holding) a belief, and ascertain whether or not they are good reasons. Good reasons involve attention to rational or intellectual standards such as evidential support, objectivity, justification and truth. My discussion of the moral dimensions of epistemological questions will follow the path delineated by W.K. Clifford (1877) in his essay “The Ethics of Belief”. Within the context of the notions of intellectual virtues and vices, I will argue that intellectual integrity and epistemic responsibility entail the acceptance of the aforementioned standards and an avoidance of credulity. Recently, however, the Enlightenment project of rationality has come under serious attack from feminist philosophers, neo pragmatists, post-modernist philosophers and proponents of the “sociology of knowledge” who, in their efforts to avoid dogmatism, claim that knowledge lacks foundations, truth is relative to culture or “conceptual scheme,” and objectivity a myth. Although a thorough treatment and discussion of the views advanced by these groups far exceeds the scope of this thesis, their claims are, I shall argue, self-refuting and entail a destructive relativism and possible descent into radical skepticism. For the most part, I will focus my criticisms on Pragmatism, particularly the variety espoused by Richard Rorty, arguably the most influential contemporary philosopher. If the extremes of radical skepticism and dogmatism are to be averted, educators must adopt the premise that knowledge is possible but at the same time accept the fact that much of what we claim to know is uncertain. Hence, many of our beliefs should be regarded as transitory and, therefore, held tentatively. I shall argue that by assuming a posture of humility in the face of knowledge claims, holding to a realist and fallibilist theory of knowledge, entertaining beliefs with a healthy skepticism and abandoning the “quest for certainty” (as Dewey has asserted), we can avoid dogmatism, indoctrination and the intellectual vice of credulity. If we value autonomous critical thinkers as an important component within a liberal democratic society, then these dispositions ought to be fostered in our students. This dispositional approach to critical thinking I refer to as constructive skepticism and will argue that it is a necessary requirement for any serious critical inquirer.

description: We present results of the search for supersolid 4He using low-frequency, low-level mechanical excitation of a solid sample grown and cooled at fixed volume. We have observed low frequency non-linear resonances that constitute anomalous features. These features, which appear below about 0.8 K, are absent in 3He. The frequency, the amplitude at which the nonlinearity sets in, and the upper temperature limit of existence of these resonances depend markedly on the sample history.

description: This paper draws on populist political communication in Europe with a view to identifying the convergence of Eurosceptic framing among EU countries. After focusing on the general hosting environment of populism and the dangers that threat EU member states when populist practice governs, it presents some specific examples of populist rhetoric, in order to resolve the mechanisms of populism when emotional framing leads. The proposed framework projects political communication on specific attitudes/trends in Mass Media, underlining comedic performance and cynicism. The research, which studies the emotional rhetoric of two Danish populist political figures in Social Media, interprets Eurosceptic negativism, fear, aggression and sarcasm as a stereotypic path for gaining popularity. These emotional stereotypes have been cultivated in political satire, tabloid talk shows and news parody programs during the last decades, by transforming politics into a sort of entertaining collective experience. I argue that the study of populism in Social Media together with the analysis of the interaction between Social Media and Mass Media is a way to effectively discuss some of the mechanisms of populism today.

Επικεντρώνεται στο γενικό περιβάλλον φιλοξενίας του λαϊκισμού και στους κινδύνους που απειλούν τα κράτη μέλη της ΕΕ κατά την κυριαρχία της λαϊκιστικής πρακτικής και έπειτα παρουσιάζει συγκεκριμένα παραδείγματα λαϊκιστικής ρητορικής, προκειμένου να ερμηνευτούν οι μηχανισμοί του λαϊκισμού όταν αυτός ορίζεται από συναισθηματική επιχειρηματολογία. Το προτεινόμενο πλαίσιο προβάλει την πολιτική επικοινωνία σε συγκεκριμένες συμπεριφορές / τάσεις των ΜΜΕ, υπογραμμίζοντας τις κωμικές διαστάσεις και τον κυνισμό. Η έρευνα, η οποία μελετά τη συναισθηματική ρητορική δύο Δανών λαϊκιστών πολιτικών στα μέσα κοινωνικής δικτύωσης, ερμηνεύει τον ευρωσκεπτικιστοκό αρνητισμό, τον φόβο, την επιθετικότητα και τον σαρκασμό ως στερεοτυπικούς δρόμους που στοχεύουν στη δημοτικότητα. Αυτά τα συναισθηματικά στερεότυπα έχουν καλλιεργηθεί στις πολιτικές σάτηρες, τα tabloid talk shows και τα προγράμματα ειδήσεων κατά τις τελευταίες δεκαετίες, μετατρέποντας την πολιτική σε ένα είδος διασκεδαστικής συλλογικής εμπειρίας. Υποστηρίζω ότι η μελέτη του λαϊκισμού στα Social Media μαζί με την ανάλυση της αλληλεπίδρασης μεταξύ των μέσων κοινωνικής δικτύωσης και των μέσων μαζικής ενημέρωσης είναι ένας τρόπος για να ερμηνεύσουμε αποτελεσματικά ορισμένους από τους μηχανισμούς του λαϊκισμού σήμερα.

description: Rigid spherical microphone arrays (RSMAs) have been widely used in ambisonics sound field recording. While it is desired to combine the information captured by a grid of densely arranged RSMAs for expanding the area of accurate reconstruction, or sweet-spots, this is not trivial due to inter-array interference. Here we propose multiple scattering ambisonics, a method for three-dimensional ambisonics sound field recording using multiple acoustically interacting RSMAs. Numerical experiments demonstrate the sweet-spot expansion realized by the proposed method. The proposed method can be used with existing RSMAs as building blocks and opens possibilities including higher degrees-of-freedom spatial audio.

description: The aims of this master thesis are: a) the development and evaluation of a pre-processing pipeline for polysomnograhic recordings which include: electroencephalographic, electrocardiographic, electromyographic and electrooculographic recordings and b) to study and evaluate the appropriateness of functional connectivity metrics and brain network characteristics for robust automatic sleep staging and the study of the macro-architecture of sleep. In this thesis the biological process of sleep is described along with the biological signals that were recorded during sleep, as well as the features that were extracted from each recording. Two main methods of Artificial Intelligence that were used for automatic sleep staging are also analyzed. Finally the data used in the experimental process are described and the results from applying the two aforementioned methods. From the experimental results it can be concluded that the pre-processing pipeline developed, the biological signal features extracted and the classification methods used, are suitable for robust sleep stage recognition and classification

description: Despite numerous advances in the field of tissue engineering and regenerative medicine, monitoring the formation of tissue regeneration and its metabolic variations during culture is still a challenge and mostly limited to bulk volumetric assays. Here, a simple method of adding capsules based optical sensors in cell seeded 3D scaffolds is presented and the potential of these sensors to monitor the pH changes in space and time during cell growth is demonstrated. It is shown that the pH decreased over time in the 3D scaffolds, with a more prominent decrease at the edges of the scaffolds. Moreover, the pH change is higher in 3D scaffolds compared to monolayered 2D cell cultures. The results suggest that this system, composed by capsules based optical sensors and 3D scaffolds with predefined geometry and pore architecture network, can be a suitable platform for monitoring pH variations during 3D cell growth and tissue formation. This is particularly relevant for the investigation of 3D cellular microenvironment alterations occurring both during physiological processes, such as tissue regeneration, and pathological processes, such as cancer evolution.

description: The present study investigated how much interculturally competent and ready 190 teachers from different regions of Greece are, as far as education of Roma pupils’ is concerned. Teachers’ intercultural competence and readiness is investigated through dimensios that are reflected in culturally responsive teaching. In particular, a questionnaire was drawn up which included the views of teachers on specific dimensions of culturally responsive teaching. The analysis confirmed the validity and reliability of the created scales. It appeared that teachers have perceptions that are positively oriented to the principles and practices of culturally responsive teaching but at a moderate level, as are the practices they apply. They are presented various factors that relate to the characteristics of the teachers, but also to the context itself, and they have been shown to influence the degree of intercultural competence and readiness. The findings of the research are discussed in relation to the great need of teachers for further education on issues of intercultural education, language and culture of Roma

description: We report the crystal structures and properties of iron hydrate compounds. These hydrates have 2D topologies and crystallize with three different structural features depending on the number of weakly bonded water molecules. Coordinated water molecules occupy the axial sites of the iron ion and support a network of hydrogen-bonded water molecules in the interlayer region. Crystal structures of these hydrates are known for Mn, Co, and Ni but not for Fe. The structure for the solids considered herein was solved and refined from powder XRD patterns complemented by IR, UV/Vis-NIR, Mössbauer, and TG data. The relevance of this structural study is related to the application of Hofmann-like coordination polymers as spin-crossover materials when the coordinated water molecules are replaced by dipyridines, pyridine, and derivatives that form pillars between adjacent layers. Upon dehydration of these solids, a reactive material is formed by assembly of tetrahedral iron ions with square planar nickel ions.

description: Optical spin pumping of color centers in diamond is presently attracting broad interest as a platform for dynamic nuclear polarization at room temperature, but the mechanisms involved in the generation and transport of polarization within the host crystal are still partly understood. Here we investigate the impact of continuous radio-frequency (RF) excitation on the generation of nuclear magnetization produced by optical illumination. In the presence of RF excitation far removed from the nuclear Larmor frequency, we witness a magnetic-field-dependent sign reversal of the measured nuclear spin signal when the drive is sufficiently strong, a counter-intuitive finding that immediately points to non-trivial spin dynamics. With the help of analytical and numerical modeling, we show our observations indicate a modified form of 'solid effect', down-converted from the microwave to the radio-frequency range through the driving of hybrid transitions involving one (or more) nuclei and two (or more) electron spins. Our results open intriguing opportunities for the manipulation of many-electron spin systems by exploiting hyperfine couplings as a means to access otherwise forbidden intra-band transitions.

description: The diffusion radius of the 1S muonic hydrogen atoms in gaseous H_2 targets with various deuterium admixtures has been determined for temperatures T=30 and 300 K. The Monte Carlo calculations have been performed using the partial differential crosssections for $pμ$ and $dμ$ atom scattering from the molecules H$_2$, HD and D$_2$. These cross sections include hyperfine transitions in the muonic atoms, the muon exchange between the nuclei $p$ and $d$, and rotational-vibrational transitions in the target molecules. The Monte Carlo results have been used for preparing the time-projection chamber for the high-precision measurement of the nuclear $μ^{-}$ capture in the ground-state $pμ$ atom, which is now underway at the Paul Scherrer Institute.

Entropy in Nonequilibrium Statistical Mechanics

Year: 2006
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Entropy in nonequilibrium statistical mechanics is investigated theoretically so as to extend the well-established equilibrium framework to open nonequilibrium systems. We first derive a microscopic expression of nonequilibrium entropy for an assembly of identical bosons/fermions interacting via a two-body potential. This is performed by starting from the Dyson equation on the Keldysh contour and following closely the procedure of Ivanov, Knoll and Voskresensky [Nucl. Phys. A {\bf 672} (2000) 313]. The obtained expression is identical in form with an exact expression of equilibrium entropy and obeys an equation of motion which satisfies the $H$-theorem in a limiting case. Thus, entropy can be defined unambiguously in nonequilibrium systems so as to embrace equilibrium statistical mechanics. This expression, however, differs from the one obtained by Ivanov {\em et al}., and we show explicitly that their ``memory corrections'' are not necessary. Based on our expression of nonequilibrium entropy, we then propose the following principle of maximum entropy for nonequilibrium steady states: ``The state which is realized most probably among possible steady states without time evolution is the one that makes entropy maximum as a function of mechanical variables, such as the total particle number, energy, momentum, energy flux, etc.'' During the course of the study, we also develop a compact real-time perturbation expansion in terms of the matrix Keldysh Green's function.

description: Two new ruthenium(II)-complexes, [Ru(Ang)((benzene)Cl2] (RuB-Ang) and [Ru(Ang)((p-cymene)Cl2] (RuC-Ang), were synthesized using andrographolide (Ang) as a ligand with [RuCl2(arene)]2 (arene = benzene or p-cymene) and characterized by various spectroscopic techniques. These techniques ascertained the formation of the complexes. An assessment of the antioxidant activity of the compounds indicated better scavenging activity against ABTS•+, DPPH•, O2−, NO• and OH− radicals. The cytotoxic activities of RuB-Ang and RuC-Ang have been evaluated against A549 (human lung) and HeLa (human cervical) cancer cell lines. The complexes exhibited superior anticancer activity to cisplatin and was non-toxic towards human umbilical vein endothelial (HUVEC) cells. The morphological changes of the HeLa and A549 cells with the complexes have been studied by AO-EB and DAPI staining methods. The cytotoxic nature of the compounds was RuC-Ang > RuB-Ang > cisplatin > ligand.

description: High resolution images are widely used in our daily life, whereas high-speed video capture is challenging due to the low frame rate of cameras working at the high resolution mode. Digging deeper, the main bottleneck lies in the low throughput of existing imaging systems. Towards this end, snapshot compressive imaging (SCI) was proposed as a promising solution to improve the throughput of imaging systems by compressive sampling and computational reconstruction. During acquisition, multiple high-speed images are encoded and collapsed to a single measurement. After this, algorithms are employed to retrieve the video frames from the coded snapshot. Recently developed Plug-and-Play (PnP) algorithms make it possible for SCI reconstruction in large-scale problems. However, the lack of high-resolution encoding systems still precludes SCI's wide application. In this paper, we build a novel hybrid coded aperture snapshot compressive imaging (HCA-SCI) system by incorporating a dynamic liquid crystal on silicon and a high-resolution lithography mask. We further implement a PnP reconstruction algorithm with cascaded denoisers for high quality reconstruction. Based on the proposed HCA-SCI system and algorithm, we achieve a 10-mega pixel SCI system to capture high-speed scenes, leading to a high throughput of 4.6G voxels per second. Both simulation and real data experiments verify the feasibility and performance of our proposed HCA-SCI scheme.

description: Regression problems are traditionally analyzed via univariate characteristics like the regression function, scale function and marginal density of regression errors. These characteristics are useful and informative whenever the association between the predictor and the response is relatively simple. More detailed information about the association can be provided by the conditional density of the response given the predictor. For the first time in the literature, this article develops the theory of minimax estimation of the conditional density for regression settings with fixed and random designs of predictors, bounded and unbounded responses and a vast set of anisotropic classes of conditional densities. The study of fixed design regression is of special interest and novelty because the known literature is devoted to the case of random predictors. For the aforementioned models, the paper suggests a universal adaptive estimator which (i) matches performance of an oracle that knows both an underlying model and an estimated conditional density; (ii) is sharp minimax over a vast class of anisotropic conditional densities; (iii) is at least rate minimax when the response is independent of the predictor and thus a bivariate conditional density becomes a univariate density; (iv) is adaptive to an underlying design (fixed or random) of predictors.

The proposed QND scheme functions even if the ancillary photon is replaced with weak light composed of vacuum and one-photon states. Although the detection scheme is designed for entanglement sharing applications, it is also suitable for general purification of a single photon state.

description: We study a 4+1 dimensional pure Abelian Gauge model on the lattice with two anisotropic couplings independent of each other and of the coordinates. A first exploration of the phase diagram using mean field approximation and monte carlo techniques has demonstrated the existence of a new phase, the so called Layer phase, in which the forces in the 4-D subspace are Coulomb-like while in the transverse direction (fifth dimension) the force is confining. This allows the possibility of a gauge field localization scheme. In this work the use of bigger lattice volumes and higher statistics confirms the existence of the Layer phase and furthermore clarifies the issue of the phase transitions' order. We show that the Layer phase is separated from the strongly coupled phase by a weak first order phase transition. Also we provide evidence that the Layer phase is separated by the five-dimensional Coulomb phase with a second order phase transition and we give a first estimation of the critical exponents.

description: Tumour spheroids have the potential to be used as preclinical chemosensitivity assays. However, the production of three dimensional (3D) tumour spheroids remains challenging as not all tumour cell lines form spheroids with regular morphologies and spheroid transfer often induces disaggregation. In the field of pancreatic cancer, the MiaPaCa-2 cell line is an interesting model for research but it is known for its difficulty to form stable spheroids; also, when formed, spheroids from this cell line are weak and arduous to manage and to harvest for further analyses such as multiple staining and imaging. In this work, we compared different methods (i.e. hanging drop, round bottom wells and Matrigel embedding, each of them with or without methylcellulose in the media) to evaluate which one allowed to better overpass these limitations. Morphometric analysis indicated that hanging drop in presence of methylcellulose leaded to well-organized spheroids; interestingly, quantitative PCR (qPCR) analysis reflected the morphometric characterization, indicating that same spheroids expressed the highest values of CD44, VIMENTIN, TGF beta1 and Ki67. In addition, we investigated the generation of MiaPaCa-2 spheroids when cultured on substrates of different hydrophobicity, in order to minimize the area in contact with the culture media and to further improve spheroid formation.

description: Identifying the two physical mechanisms behind the production and sustenance of the quiescent solar corona and solar wind poses two of the outstanding problems in solar physics today. We present analysis of spectroscopic observations from the Solar and Heliospheric Observatory that are consistent with a single physical mechanism being responsible for a significant portion of the heat supplied to the lower solar corona and the initial acceleration of the solar wind; the ubiquitous action of magnetoconvection-driven reprocessing and exchange reconnection of the Sun's magnetic field on the supergranular scale. We deduce that while the net magnetic flux on the scale of a supergranule controls the injection rate of mass and energy into the transition region plasma it is the global magnetic topology of the plasma that dictates whether the released ejecta provides thermal input to the quiet solar corona or becomes a tributary that feeds the solar wind.

Channel correction via quantum erasure

description: By exploiting a generalization of recent results on environment-assisted channel correction, we show that, whenever a quantum system undergoes a channel realized as an interaction with a probe, the more efficiently the information about the input state can be erased from the probe, the higher is the corresponding entanglement fidelity of the corrected channel, and vice-versa. The present analysis applies also to channels for which perfect quantum erasure is impossible, thus extending the original quantum eraser arrangement, and naturally embodies a general information-disturbance tradeoff.

description: We observe -9.01$\pm$0.14 dB of squeezing and +15.12$\pm$0.14 dB of antisqueezing with a local oscillator phase locked in homodyne measurement. In reference [1], two main factors are pointed out which degrade the observed squeezing level: phase fluctuation in homodyne measurement and intracavity losses of an optical parametric oscillator for squeezing. We have improved the phase stability of homodyne measurement and have reduced the intracavity losses. We measure pump power dependences of the squeezing and antisqueezing levels, which show good agreement with theoretical calculations taking account of the phase fluctuation.

description: Organ-on-a-chip (OoCs) platforms could revolutionize drug discovery and might ultimately become essential tools for precision therapy. Although many single-organ and interconnected systems have been described, the immune system has been comparatively neglected, despite its pervasive role in the body and the trend towards newer therapeutic products (i.e., complex biologics, nanoparticles, immune checkpoint inhibitors, and engineered T cells) that often cause, or are based on, immune reactions. In this review, we recapitulate some distinctive features of the immune system before reviewing microfluidic devices that mimic lymphoid organs or other organs and/or tissues with an integrated immune system component.

description: Three new 2D heteronuclear tetracyanonickelate(II) complexes with 4-ethylpyridine (4epy), [Cu(4epy)2Ni(µ-CN)4]n (1), [Zn(4epy)2Ni(µ-CN)4]n (2) and [Cd(4epy)2Ni(µ-CN)4]n (3), were synthesized and characterized by vibrational (FT-IR and Raman) spectroscopy, elemental and thermal analyses, single crystal (SC-XRD) and powder X-ray diffraction (PXRD) techniques. The single crystal X-ray analysis reveals that each metal ion (Cu(II), Zn(II), and Cd(II)) is coordinated by two nitrogen atoms from 4epy ligands and four nitrogen atoms from cyanide ligands and Ni(II) ions are coordinated by four carbon atoms from cyanide ligands showing a distorted octahedral and square planar coordination geometries, respectively. The most outstanding features of the complexes are the weak intermolecular C–H⋅⋅⋅Ni interactions between the Ni(II) ion and hydrogen atom of the ethyl group of the 4epy ligand. Adjacent 2D structures are further combined by these C–H⋅⋅⋅Ni interactions, generating a 3D network. The heterogeneous catalytic activity of 3 was investigated for oxidation of some primary and secondary aliphatic or aromatic alcohols; no acid formation was observed in some aromatic alcohols after 24 h and 100% aldehyde selectivity was determined.

description: The dynamics of a test particle interacting with diffusing impurities in one dimension is investigated analytically and numerically. In the absence of an applied external force, the dynamics of the particle can be characterized by a distribution of monotonic excursions $Δx$, which scales as a power law with an exponent $τ_{Δx} = 4/3$. When the particle is driven at a slow constant velocity, there is again a power law distribution for the monotonic changes of the force $ΔF$, which is characterized by a similar exponent $τ_{ΔF}=4/3$. These results can be understood from the theory of random walks.

description: Herein we describe the synthesis of a library of new mercury complexes, including some dimers and polymeric species. Initially, a phosphonium salt, [PPh3CH2C(O)C6H4–m-OCH3]Br (S), was synthesized from triphenylphosphine (PPh3) and BrCH2C(O)C6H4-m-OCH3 in acetone. We then reacted this phosphonium salt with an appropriate base to acquire a new phosphorus ylide monodentate, PPh3=C(H)C(O)C6H4-m-OCH3 (Y). Finally, we treated the synthesized ligand with mercury halides in dry CH3OH to form C-coordinated complexes of the form [HgX(PPh3C(H)C(O)C6H4-m-OCH3) (μ-X)]2 [X = Cl (1), Br (2), I (3)], [(PPh3=C(H)C(O)C6H4-m-OCH3)Hg(NO3)2]n (4). We characterized these compounds using CHN analysis, FT-IR, NMR (1H, 13C and 31P) and density functional theory. We elucidated the structure of 2 by single-crystal X-ray diffraction. The results establish that 1, 2 and 3 have dimeric structures, while a polymeric structure is suggested for 4. The antioxidant activity of all compounds in DMSO was assessed using a DPPH free radical scavenging method. Also, the nature of metal-ligand (C→Hg) bonding in 1, 2 and 3 have been investigated using natural bond orbital (NBO) and energy-decomposition analyses (EDA).

description: We analyze the charmonium states by testing a phenomenological nonrelativistic potential and propose a new set of parameters. This new set of parameters are fixed using only the lowest lying S-wave states of charmonia where the spin-orbit and tensor interactions will not contribute. After fitting the parameters we analyze the whole fine structure of charmonium states taking into account the spin-orbit and tensor interactions too. Calculations showed that the nonrelativistic potential model with the phenomenologically defined parameters is indeed well approximation for describing the charmonium states.

description: We analyze, within a mean-field approach, the stationary states of the kinetic spin-3/2 Blume-Capel model by the Glauber-type stochastic dynamics and subject to a time-dependent oscillating external magnetic field. The dynamic phase transition points are obtained by investigating the behavior of the dynamic magnetization as a function of temperature and as well as calculating the Liapunov exponent. Phase diagrams are constructed in the temperature and crystal-field interaction plane. We find five fundamental types of phase diagrams for the different values of the reduced magnetic field amplitude parameter (h) in which they present a disordered, two ordered phases and the coexistences phase regions. The phase diagrams also exhibit a dynamic double critical end point for 05.06.
