Defining critical literacy
No full textThis article traces the lineage of critical literacy from Freire through critical pedagogies and discourse analysis. The author discusses the need for a contingent definition of critical literacy, as a situated and contextual response to political economies, institutional and cultural relations of power
Association of Total Shareholder Return with other value based measures of financial performance
No full textPurpose- The purpose of this paper is to examine the relationship between total shareholder return (TSR) and other value based measures like created shareholder value (CSV), market value added (MVA), and economic profit (EP) in Indian banking sector and provide empirical evidences.
Design/methodology/approach- The paper uses a sample of 21 listed Indian banks segregated into 10 public sector banks and 11 private sector banks. The study period ranges from year 200-01 to 2009-10. Pooled ordinary least square regression is used to test the relationship between the variables in question.
Findings- The results reveal that CSV, EP individually explain the variation in TSR of Indian banks. Whereas, MVA as an individual independent variable does not explain variation in TSR of Indian banks. However CSV, MVA and EP jointly explain variation in TSR of Indian banks.
Research limitations/implications- The study was specifically restricted to listed banks in India. It did not consider unlisted banks.
Originality/value- Author concludes that individual value based measure should not be blindly used while measuring the shareholder value creation by a firm. Rather, a mix of these measures should be used to accurately measure the shareholder value creation.

STABLE ENERGY-EFFICIENT MACRO-SCALE PARTIAL FLOW-BOILING OPERATIONS USING MICROSTRUCTURED SURFACES AND ULTRASONICS
No full textControlled but explosive growth in vaporization rates is made feasible by ultrasonic acoustothermal heating of the microlayers associated with micro-scale nucleating bubbles within the microstructured boiling surface/region of a millimeter-scale single-channel heat exchanger (HX) – part of a typically multi-channel heat-sink. The experiments illustrate the achievement of a remarkably high stable heat flux (10 – 80 W/cm2) for a partial flow-boiling-based cooling approach and exceptional efficiency through active/passive enhancement in the vaporization rates into the heterogeneously nucleated micro-bubbles (through acoustothermal heating of their microlayers) and their removal rates (typically within the passive microstructured region of boiling). A controlled but explosive growth in evaporation and departure rates into the nucleated micro-bubbles during flow-boiling of 3M Novec HFE 7000 is enabled by the use of inexpensive layers of woven copper mesh to form a microstructured boiling surface/region. These microstructured boiling regions are subjected to nano/micro-scale amplitude ultrasonic (~1 - 6 MHz) and sonic (\u3c 2 kHz, typically) vibrations – induced by one or two very thin (0.5 – 1.5 mm) ultrasonic Piezoelectric-transducers (termed Piezos) that are placed and actuated from outside the heat-sink. These Piezos, powered by specialized drivers, are positioned externally to the mini-channel heat sink. The ultrasonic frequencies are for sub-structural micro vibrations whereas the lower sonic frequencies are for suitable resonant structural micro-vibrations that assist in bubble removal and liquid filling processes (a type of vibrations actuated process for the multi-layered mesh microstructure, whose single layers were Wenzell filling under static pre-bonded conditions). The flow and the Piezos’ actuation control allow an approximately 5-fold increase in heat transfer coefficient (HTC) value – going from about 9000 W/m2-°C associated with microstructured no-Piezos cases to 50000 W/m2-°C at a representative heat flux of about 25 W/cm2 while the saturated (or slightly sub-cooled) liquid at the test-section inlet boils between 40 - 60 ℃, while heat-sink exit pressures vary within the range of 0.9 – 1.5 bars. However, when striving for desired high heat fluxes, certain operational challenges arise. These include significant pressure drops and instabilities within the heat sink, ultimately leading to either Critical Heat Flux (CHF) instability or similar issues at the system level across its components. The CHF suppression issues are separately addressed (not part of this thesis). The flow-loop hardware has been strategically chosen. The flow-loop control further ensures that the millimeter-scale rectangular cross-section flow channel, with its bottom heated-surface microstructured, operates in a way that there are no vapor-compressibility-induced flow instabilities at the system level. The reported experimental results, use a newly revised flow loop, the setup has a boiling test section, three Coriolis flow meters, absolute pressure transducers, temperature sensors, cartridge heaters, power meters, air/liquid-cooled condensers, two gear pumps, a reservoir, copper tubing, superheater, one-way valves, two-way valves, shut-valves, filters, etc. and several other accessory devices - including bonded Piezos, Piezo drivers, etc. Furthermore, the need for substantial total inlet mass-flow rate and extensive vapor volume flow rates to support such (or higher) high heat-flux values results in system-level challenges, which if not properly addressed (as is done here), would result in impractical pumping power requirements and undesirable device-level performances (such as condenser instabilities, cavitation in and around gear pumps and Coriolis Meters), including flow instabilities (in the absence of suitable flow controls). To address these concerns and attain stable operations with reduced pressure drops, a new experimental setup has been devised and reported here
A rare case report on atypical odontalgia with psychological implications
No full textPsychosomatic or somatoform disorders are among the most common psychiatric disorders found in general practice. A psychosomatic disorder involves both body and mind. These diseases have physical symptoms originating from mental or emotional causes. Most common ones are stress, anxiety and depression. A wide spectrum of psychiatric disorders may influence the orofacial region, where unfortunately they remain unrecognized due to limited nature of their presenting features. We here present a case report of atypical odontalgia in an elderly male secondary to underlying psychological distress
Life cycle assessment for Thermolysis and electrolysis integration in the copper-chlorine cycle of hydrogen production
No full textProduction, transformation, and use of energy are the main causes of many environmental problems including acid precipitation, ozone depletion, and climate change. Therefore, there is a global push for sustainable energy alternatives. One promising paradigm of a clean energy system is the hydrogen economy. However, current methods of hydrogen production are often unsustainable as they are based primarily on fossil fuels such as natural gas or coal, which release CO2 into the atmosphere. Promising alternatives for sustainable hydrogen production are thermochemical cycles. In thermochemical cycles for hydrogen production, the overall water splitting into hydrogen and oxygen is achieved through a series of reactions. This paper discusses various designs for integration of the molten salt reactor and electrochemical cell in a thermochemical copper-chlorine (Cu-Cl) cycle. A life cycle assessment is used to aid in the selection process of the best design for integration. This is done based on a point system within an impact category, where the design with the lowest points is taken to be the most feasible and hence chosen for integration of the cycle
Generalizing Non-punctuality for Timed Temporal Logic with Freeze Quantifiers
No full textMetric Temporal Logic (MTL) and Timed Propositional Temporal Logic (TPTL) are prominent real-time extensions of Linear Temporal Logic (LTL). In general, the satisfiability checking problem for these extensions is undecidable when both the future U and the past S modalities are used. In a classical result, the satisfiability checking for MITL[U,S], a non-punctual fragment of MTL[U,S], is shown to be decidable with EXPSPACE complete complexity. Given that this notion of non-punctuality does not recover decidability in the case of TPTL[U,S], we propose a generalization of non-punctuality called non-adjacency for TPTL[U,S], and focus on its 1-variable fragment, 1-TPTL[U,S]. While non-adjacent 1-TPTL[U,S] appears to be a very small fragment, it is strictly more expressive than MITL. As our main result, we show that the satisfiability checking problem for non-adjacent 1-TPTL[U,S] is decidable with EXPSPACE complete complexity.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Manuel Mazo J
Placing In-between: thinking through architecture in the construction of colonial modern Identities
No full textThis article addresses the topical notions of hybridity and ‘in-between-ness’ as salient points of intersection between critical architectural inquiry and postcolonial studies. Focusing on domestic architecture in colonial-modern India, it examines the problematical role of the built environment in the construction and re-production of identities in nation-building processes. In the light of the equally problematical engagement of architectural form and symbolism in the increasingly reductive and reactionary identity politics of postcolonial India, the article discerns an alternative function that architecture may perform as an ‘in-between’ space enabling cultural intersection and innovation. Through a comparative interpretation of architectural references to the conundrums of hybridity in two historically and stylistically distinct novels about the awakening of colonial-modern India into postcolonial consciousness—John Masters’ Bhowani Junction (1954), and Salman Rushdie's The Moor's Last Sigh (1996)—literary fiction is engaged as an apposite representation of the ‘place’ of the built environment in the emerging conceptual and cultural landscapes of a new nation. Buildings are not merely ‘backdrops’ to the historical dramas enacted within and between them, the author argues, but cognitive constructions in which identities (national, communal and individual) can be negotiated creatively across cultural boundaries. In addition to aesthetic form and operative function, Architecture, like Literature, also has an ethical function as a heuristic framework for thinking.Peter Scrive
