description: Irradiance dependence of excitonic nonlinear absorption in Cadmium Sulfide (CdS) nanocrystals has been studied by using Z-scan method with nanosecond laser pulses. The wavelength dependence of nonlinear absorption has also been measured near the excitonic transition of 1S(e)-1S3/2(h). We observe the saturable absorption, which can be described by a third-order and a fifth-order nonlinear process for both 3.0-nm-sized and 2.3-nm-sized CdS nanocrystals. The experimental results show that the excitonic nonlinear absorption of CdS nanocrystals is greatly enhanced with decreasing particle size. A two-level model is utilized to explain both irradiance and wavelength dependence of the excitonic nonlinearity.

description: Transparent conducting or semiconducting oxides are important materials for (transparent) optoelectronics and power electronics applications. While most of these oxides can be doped n-type only with room-temperature electron mobilities on the order of 100cm^2/Vs p-type oxides are needed for the realization of pn-junction devices but typically suffer from exessively low (<<1cm^2/Vs) hole mobilities. Tin monoxide (SnO) is one of the few p-type oxides with a higher hole mobility, lacking a well-established understanding of its hole transport properties. Moreover, growth of SnO is complicated by its metastability with respect to SnO2 and Sn, requiring epitaxy for the realization of single crystalline material typically required for high-end applications. Here, we give a comprehensive account on the epitaxial growth of SnO, its (meta)stability, and its thermoelectric transport properties in the context of the present literature. Textured and single-crystalline, unintentionally-doped p-type SnO(001) films are grown by plasma-assisted molecular beam epitaxy. The metastability of this semiconducting oxide is addressed theoretically through an equilibrium phase diagram. Experimentally, the related SnO growth window is rapidly determined by an in-situ growth kinetics study as function of Sn-to-O-plasma flux ratio and growth temperature. The presence of secondary Sn and SnOx (1 < x <= 2) phases is comprehensively studied by different methods, indicating the presence of Sn3O4 or Sn as major secondary phases, as well as a fully oxidized SnO2 film surface. The hole transport properties, Seebeck coefficient, and density-of-states effective mass are determined and critically discussed in the context of the present literature on SnO, considering its anisotropic hole-effective mass.

description: Οι σύγχρονοι καταναλωτές στρέφουν το ενδιαφέρον τους όλο και περισσότερο στην διατήρηση της υγειάς τους μέσω της διατροφής, αναζητώντας οι ίδιοι τα οφέλη που προκύπτουν από την κατανάλωση προϊόντων που κυκλοφορούν στο εμπόριο. Τέτοια προϊόντα αποτελούν και αυτά που περιέχουν προβιοτικά ή πρεβιοτικά. Ως αποτέλεσμα, στην παγκόσμια αγορά υπάρχει σημαντική αύξηση της ζήτησης προϊόντων με προβιοτικά. Τα προβιοτικά μπορούν να χρησιμοποιηθούν σε μια ποικιλία προϊόντων, ωστόσο τα επιδόρπια γάλακτος είναι μια κατηγορία τροφίμων που παρουσιάζει αυξημένο ενδιαφέρον καθώς μπορεί να καταναλωθεί από όλες τις ηλικιακές ομάδες. Επομένως, σκοπός της παρούσας διπλωματικής εργασίας είναι να αναλύσει την σημασία που έχουν τα προβιοτικά στην υγεία του καταναλωτή καθώς και τη χρήση τους στα επιδόρπια γάλακτος. Για να επιτευχθεί ο παραπάνω σκοπός χρησιμοποιήθηκε η βάση PubMed για μελέτες που σχετίζονται με τα ευεργετικά αποτελέσματα των προβιοτικών στην ανθρώπινη υγεία. Επιπλέον, γίνεται αναφορά σε πλήθος μελετών που ερευνούν την προσθήκη προβιοτικών στα επιδόρπια γάλακτος, μελετώντας τη βιωσιμότητα του προβιοτικού στελέχους υπό την επίδραση των διαφόρων συστατικών, τα φυσικοχημικά και αισθητηριακά χαρακτηριστικά των προϊόντων για την αποδοχή τους από το καταναλωτικό κοινό, την τεχνολογία παραγωγής προβιοτικών και τέλος την ινουλίνη ως υποκατάστατό λίπους. Από την ανασκόπηση που πραγματοποιήθηκε προέκυψαν τα ακόλουθα αποτελέσματα. Όσον αφορά τα οφέλη που προκύπτουν για την υγειά, το ερευνητικό ενδιαφέρον αυξάνεται ραγδαία για στατιστικά σημαντικά αποτελέσματα. Συγκεκριμένα οι ερευνητές δεν γνωρίζουν ποια προβιοτικά είναι χρήσιμα και ποια όχι. Επίσης, δεν γνωρίζουν την ποσότητα των προβιοτικών ή ποιος θα ήταν πιο πιθανό να ωφεληθεί. Εντούτοις, η προσπάθεια για την καταπολέμηση διαφόρων παθήσεων αυξάνεται. Η ενσωμάτωση των προβιοτικών στα επιδόρπια γάλακτος αποτελεί μια υποσχόμενη τάση. Ωστόσο, η βιωσιμότητα των προβιοτικών στελεχών απαιτεί περαιτέρω έρευνα για να επιτευχθεί η σταθερότητα των μικροοργανισμών αυτών με αποδεκτά φυσικοχημικά και αισθητηριακά χαρακτηριστικά. Τέλος, η χρήση του συστατικού ινουλίνης αποτελεί ένα από τα πιο κοινά χρησιμοποιούμενα συστατικά στα επιδόρπια με βάση το γάλα τόσο για τις τεχνολογικές ιδιότητες που παρουσιάζει όσο και για τα οφέλη που προσφέρει στην υγεία. Συμπερασματικά, προκύπτει ότι απαιτείται περαιτέρω έρευνα στο τομέα των προβιοτικών τόσο για τη χρήση στους στα γαλακτοκομικά προϊόντα και κυρίως στα επιδόρπια γάλακτος όσο και για τα πιθανά οφέλη που μπορεί να προκύπτουν από την κατανάλωση τους.

description: We present a c-function for spherically symmetric, static and asymptotically flat solutions in theories of four-dimensional gravity coupled to gauge fields and moduli. The c-function is valid for both extremal and non-extremal black holes. It monotonically decreases from infinity and in the static region acquires its minimum value at the horizon, where it equals the entropy of the black hole. Higher dimensional cases, involving $p$-form gauge fields, and other generalisations are also discussed.

description: In this paper, we attempt to understand the cause of magnetostructural transformation in Mn-based antiperovskites by calculating EXAFS at the K edges of constituent metal atoms in three antiperovskite compounds, Mn$_3$GaC, Mn$_3$SnC and Mn$_3$InC. These three compounds have very different magnetic ground states despite the similar cubic structure. Our calculations show that the distortions of Mn$_6$C octahedra, which are responsible for the first-order magnetic transition to antiferromagnetic state, depends on the packing fraction of the lattice.

description: We describe medium-resolution spectroscopic observations taken with the ESO Multi-Mode Instrument in the CaII K line (3933.661 Angstroms) towards 7 QSOs located in the line-of-sight to the Magellanic Bridge. At a spectral resolution R = 6,000, five of the sightlines have a signal-to-noise ratio of 20 or higher. Definite Ca absorption due to Bridge material is detected towards 3 objects, with probable detection towards two other sightlines. Gas-phase CaII K Bridge and Milky Way abundances or lower limits for the all sightlines are estimated by the use of Parkes 21-cm HI emission line data. These data only have a spatial resolution of 14 arcminutes compared with the optical observations which have milli-arcsecond resolution. With this caveat, for the three objects with sound CaII K detections, we find that the ionic abundance of CaII K relative to HI, A=log(N(CaK)/N(HI)) for low-velocity Galactic gas ranges from -8.3 to -8.8 dex, with HI column densities varying from 3-6x10^20 cm^-2. For Magellanic Bridge gas, the values of A are 0.5 dex higher, ranging from -7.8 to -8.2 dex, with N(HI)=1-5x10^20 cm^-2. Higher values of A correspond to lower values of N(HI), although numbers are small. For the sightline towards B0251--675, the Bridge gas has two different velocities, and in only one of these is CaII K tentatively detected, perhaps indicating gas of a different origin or present-day characteristics (such as dust content), although this conclusion is uncertain and there is the possibility that one of the components could be related to the Magellanic Stream. Higher signal-to-noise CaII K data and higher resolution HI data are required to determine whether A changes with N(HI) over the Bridge and if the implied difference in the metalicity of the two Bridge components towards B0251-675 is real.

description: Many statistical practices involve choosing between a full model and reduced models where some coefficients are reduced to zero. Data were used to select a model with estimated coefficients. Is it possible to do so and still come up with an estimator always better than the traditional estimator based on the full model? The James-Stein estimator is such an estimator, having a property called minimaxity. However, the estimator considers only one reduced model, namely the origin. Hence it reduces no coefficient estimator to zero or every coefficient estimator to zero. In many applications including wavelet analysis, what should be more desirable is to reduce to zero only the estimators smaller than a threshold, called thresholding in this paper. Is it possible to construct this kind of estimators which are minimax? In this paper, we construct such minimax estimators which perform thresholding. We apply our recommended estimator to the wavelet analysis and show that it performs the best among the well-known estimators aiming simultaneously at estimation and model selection. Some of our estimators are also shown to be asymptotically optimal.

description: We report the ultrafast and large third-order nonlinear optical properties of CdS nanocrystals (NCs) embedded in a polymeric film. The CdS NCs of 2-nm radius are synthesized by an ion exchange method and highly concentrated in the two layers near the surfaces of the polymeric film. The two-photon absorption coefficient and the optical Kerr coefficient are measured with laser pulses of 250-fs duration at 800-nm wavelength. The one-photon and two-photon figures of merit are determined to be 3.1 and 1.3, respectively, at irradiance of 2 GW/cm2. The observed nonlinearities have a recovery time of ~ 1 ps. The two-photon-generated free carrier effects have also been observed and discussed. These results demonstrate that CdS NCs embedded in polymeric film are a promising candidate for optical switching applications.

description: Magnetic transition metal dichalcogenide (TMD) films have recently emerged as promising candidates to host novel magnetic phases relevant to next-generation spintronic devices. However, systematic control of the magnetization orientation, or anisotropy, and its thermal stability, characterized by Curie temperature (Tc) remains to be achieved in such films. Here we present self-intercalated epitaxial Cr1+δTe2 films as a platform for achieving systematic/smooth magnetic tailoring in TMD films. Using a molecular beam epitaxy (MBE) based technique, we have realized epitaxial Cr1+δTe2 films with smoothly tunable over a wide range (0.33-0.82), while maintaining NiAs-type crystal structure. With increasing δ, we found monotonic enhancement of Tc from 160 to 350 K, and the rotation of magnetic anisotropy from out-of-plane to in-plane easy axis configuration for fixed film thickness. Contributions from conventional dipolar and orbital moment terms are insufficient to explain the observed evolution of magnetic behavior with δ. Instead, ab initio calculations suggest that the emergence of antiferromagnetic interactions with δ, and its interplay with conventional ferromagnetism, may play a key role in the observed trends. To our knowledge, this constitutes the first demonstration of tunable Tc and magnetic anisotropy across room temperature in TMD films, and paves the way for engineering novel magnetic phases for spintronic applications.

description: High precision, high cadence radial velocity monitoring over the past 8 years at the W. M. Keck Observatory reveals evidence for a third planet orbiting the nearby (4.69 pc) dM4 star GJ 876. The residuals of three-body Newtonian fits, which include GJ 876 and Jupiter mass companions b and c, show significant power at a periodicity of 1.9379 days. Self-consistently fitting the radial velocity data with a model that includes an additional body with this period significantly improves the quality of the fit. These four-body (three-planet) Newtonian fits find that the minimum mass of companion ``d'' is m sin i = 5.89 +- 0.54 Earth masses and that its orbital period is 1.93776 (+- 7x10^-5) days. Assuming coplanar orbits, an inclination of the GJ 876 planetary system to the plane of the sky of ~ 50 degrees gives the best fit. This inclination yields a mass for companion d of m = 7.53 +- 0.70 Earth masses, making it by far the lowest mass companion yet found around a main sequence star other than our Sun. Precise photometric observations at Fairborn Observatory confirm low-level brightness variability in GJ 876 and provide the first explicit determination of the star's 96.7-day rotation period. Even higher precision short-term photometric measurements obtained at Las Campanas imply that planet d does not transit GJ 876.

description: We present a general class of spatio-temporal stochastic processes describing the causal evolution of a positive-valued field in space and time. The field construction is based on independently scattered random measures of Levy type whose weighted amplitudes are integrated within a causality cone. General n-point correlations are derived in closed form. As a special case of the general framework, we consider a causal multiscaling process in space and time in more detail. The latter is derived from, and completely specified by, power-law two-point correlations, and gives rise to scaling behaviour of both purely temporal and spatial higher-order correlations. We further establish the connection to classical multifractality and prove the multifractal nature of the coarse-grained field amplitude.

description: Prior to the 2000 planting season, some industry observers predicted acreage of genetically modified crops would decline dramatically. However, actual 2000 plantings presented a puzzle. Farmers reduced their acreage of genetically modified corn, but concurrently increased their acreage of genetically modified soybeans. We demonstrate that it may be theoretically optimal for risk-averse farmers to reduce their corn acreage but not their soybean acreage. However, past experience, attitudes, and farm size explained planting decisions to a larger degree than did risk preferences.

description: One essential component of operational space weather forecasting is the prediction of solar flares. With a multitude of flare forecasting methods now available online it is still unclear which of these methods performs best, and none are substantially better than climatological forecasts. Space weather researchers are increasingly looking towards methods used by the terrestrial weather community to improve current forecasting techniques. Ensemble forecasting has been used in numerical weather prediction for many years as a way to combine different predictions in order to obtain a more accurate result. Here we construct ensemble forecasts for major solar flares by linearly combining the full-disk probabilistic forecasts from a group of operational forecasting methods (ASAP, ASSA, MAG4, MOSWOC, NOAA, and MCSTAT). Forecasts from each method are weighted by a factor that accounts for the method's ability to predict previous events, and several performance metrics (both probabilistic and categorical) are considered. It is found that most ensembles achieve a better skill metric (between 5\% and 15\%) than any of the members alone. Moreover, over 90\% of ensembles perform better (as measured by forecast attributes) than a simple equal-weights average. Finally, ensemble uncertainties are highly dependent on the internal metric being optimized and they are estimated to be less than 20\% for probabilities greater than 0.2. This simple multi-model, linear ensemble technique can provide operational space weather centres with the basis for constructing a versatile ensemble forecasting system -- an improved starting point to their forecasts that can be tailored to different end-user needs.

description: The World Trade Organization (WTO) Agreement on Agriculture was signed in June 1994. It accomplished two things: it brought agricultural trade under the rules of WTO, and it set schedules for reducing barriers to trade under the three pillars of liberalization--market access, export assistance, and domestic support. Nine years later there has been precious little liberalization. The new Doha Round has ambitious objectives for agricultural trade liberalization. However, given recent behavior by rich developed countries, it seems unlikely that developing countries will get increased access to Northern markets or reduced competition from subsidized exports, despite their now representing a majority of WTO members.

The Western galaxy is roughly four times more luminous in the submillimetre than its Eastern counterpart. It is an extremely bright LIRG with an AGN. The classification of the Eastern source is uncertain: it could be a Seyfert 2 galaxy or a LINER. We highlight IRAS 09111-1007 as a system that necessitates further study: a double AGN ULIRG whose molecular gas content differs from other widely separated pairs and whose ULIRG phase might not be explained by current multiple merger and/or final stage ULIRG scenarios.

description: Σκοπός της παρούσης έρευνας είναι η ενδελεχής εξέταση, μέσα από βιβλιογραφική έρευνα, του ζητήματος της φοροφυγής. Συγκεκριμένα, δύο είναι τα βασικά ερευνητικά ερωτήματα γύρω από τα οποία και επί των οποίων πραγματοποιείται η έρευνα: «αποτελεί η φοροφυγή παθογένεια των ελληνικών δημοσίων οικονομικών που να είναι στο ίδιο επίπεδο με τις εκτεταμένες δημόσιες δαπάνες;» και «αντιμετωπίζεται ή όχι σε ικανοποιητικό βαθμό η φοροφυγή». Κατ’ επέκταση, μας ενδιαφέρει η ορθότητα των παρεμβάσεων του νομοθέτη στην ελληνική νομοθεσία για το εν λόγω ζήτημα. Στην ανάπτυξη των επιμέρους κεφαλαίων, αναμένεται να καλυφθούν οι επιμέρους ερευνητικοί στόχοι που θα απαντούν στην ουσία στα ανωτέρω ερευνητικά ερωτήματα. Ως προς τη μεθοδολογία που ακολουθείται κατά την έρευνα, ο επιδιωκόμενος σκοπός είναι η περιγραφή και ερμηνεία του φαινομένου της φοροφυγής, Αναφορικά με το είδος του ελέγχου των παραγόντων των προβλημάτων που τίθενται προκύπτει αιτιώδης σχέση, ενώ ο χώρος διεξαγωγής της έρευνας είναι η βιβλιογραφική επισκόπηση και αξιοποίηση των υπαρχόντων βιβλιογραφικών δεδομένων (Παρασκευόπουλος, 1993). Τέλος, το είδος της ερευνητικής μεθόδου είναι νομικό-οικονομικό, αλλά με κοινωνικοοικονομικές προεκτάσεις. Σχετικά με τη δομή παρουσίασης των ερευνητικών αποτελεσμάτων, συνοπτικά αναφέρονται τα κάτωθι: οι τρόποι μέτρησης του ΑΕΠ και ο συσχετισμός του με τη φορολογία είναι θέματα που θα εξεταστούν στο πρώτο κεφάλαιο. Βασικά θέματα του δευτέρου κεφαλαίου είναι οι διακρίσεις και τα είδη φόρων, τα επιμέρους χαρακτηριστικά τους και οι γενικές αρχές της φορολογικής εξουσίας. Στο τρίτο κεφάλαιο διερευνώνται οι αιτίες που προκαλούν το φαινόμενο της φοροφυγής και ζητήματα, όπως ο τρόπος κατανομής και το ύψος του φορολογικού βάρους, η καμπύλη Laffer για την περίπτωση της Ελλάδας και ο τρόπος διαχείρισης του δημοσίου χρήματος, μέσα από την αντίληψη των πολιτών για τις δημόσιες δαπάνες. Μέσα από αυτή την ανάλυση εξετάζεται ο βαθμός ανάπτυξης της αγοράς και συνολικά της οικονομίας. Παράγοντες όπως το μορφωτικό επίπεδο, η φορολογική ηθική και η επίδραση των ποινών διαδραματίζουν καίριο ρόλο στην έκταση του φαινομένου. Στο τέταρτο κεφάλαιο αναλύεται η αντιμετώπιση της φοροφυγής, τα προληπτικά μέτρα κατά της, όπως επίσης και τα κυρωτικά-κατασταλτικά μέτρα σε διοικητικό και ποινικό επίπεδο. Στο πέμπτο κεφάλαιο περιλαμβάνονται οι υποθέσεις μελέτης για να ακολουθήσουν μετά τα σχετικά συμπεράσματα, η παράθεση της βιβλιογραφίας που χρησιμοποιήθηκε για την εκπόνηση της παρούσας διπλωματικής εργασίας και το παράρτημα. VI Σημειώνεται πως στο τέλος κάθε κεφαλαίου προκύπτουν και αναγράφονται τα σχετικά συμπεράσματα.

description: We report on the fabrication of domain-reversed structures in LiNbO3 by means of direct electron beam lithography at room temperature without any static bias. The LiNbO3 crystals were chemically etched after the exposure of electron beam and then, the patterns of domain inversion were characterized by atomic force microscopy (AFM). In our experiment, an interesting phenomenon occurred when the electron beam wrote a one-dimensional (1-D) grating on the negative c-face: a two-dimensional (2-D) dotted array was observed on the positive c- face, which is significant for its potential to produce 2-D and three-dimensional photonic crystals. Furthermore, we also obtained 2-D ferroelectric domain inversion in the whole LiNbO3 crystal by writing the 2-D square pattern on the negative c-face. Such a structure may be utilized to fabricate 2-D nonlinear photonic crystal. AFM demonstrates that a 2-D domain-reversed structure has been achieved not only on the negative c-face of the crystal, but also across the whole thickness of the crystal.

description: This is the first econometric study of dynamic beef supply response to incorporate risk aversion or, more specifically, price variance. Autoregressive distributed lag (ADL) models are estimated for cow-calf and feedlot operations using aggregate data for Alberta. In all cases, output price variance has a negative impact on output supply and investment. Moreover, the impacts of expected price on supply response are greater in magnitude and significance than in risk-neutral models.

description: American agriculture is shifting from homogeneous commodities to differentiated products. Value differentiation, the process by which agrifood chain actors isolate, match, and exploit heterogeneity in consumer preferences and product attributes, is examined. Value differentiation is characterized by complementarities across four activities at each stage of the production chain: product characteristic measurement, product characteristic production, coordination between stages, and customer preference detection. Complementarities at the firm level are modeled using supermodularity. The model's predictions are discussed, as are potential testing approaches, and implications are presented for agrifood firms, marketing orders, and returns to research.
Learning Constitutive Relations using Symmetric Positive Definite Neural Networks

description: We present the Cholesky-factored symmetric positive definite neural network (SPD-NN) for modeling constitutive relations in dynamical equations. Instead of directly predicting the stress, the SPD-NN trains a neural network to predict the Cholesky factor of a tangent stiffness matrix, based on which the stress is calculated in the incremental form. As a result of the special structure, SPD-NN weakly imposes convexity on the strain energy function, satisfies time consistency for path-dependent materials, and therefore improves numerical stability, especially when the SPD-NN is used in finite element simulations. Depending on the types of available data, we propose two training methods, namely direct training for strain and stress pairs and indirect training for loads and displacement pairs. We demonstrate the effectiveness of SPD-NN on hyperelastic, elasto-plastic, and multiscale fiber-reinforced plate problems from solid mechanics. The generality and robustness of the SPD-NN make it a promising tool for a wide range of constitutive modeling applications.

description: While theoretically more efficient than starch-based ethanol production systems, conversion of lignocellulosic biomass to ethanol is not without major challenges. A multi-region, multi-period, mixed integer mathematical programming model encompassing alternative feedstocks, feedstock production, delivery, and processing is developed. The model is used to identify key cost components and potential bottlenecks, and to reveal opportunities for reducing costs and prioritizing research. The research objective was to determine for specific regions in Oklahoma the most economical source of lignocellulosic biomass, timing of harvest and storage, inventory management, biorefinery size, and biorefinery location, as well as the breakeven price of ethanol, for a gasification-fermentation process. Given base assumptions, gasification-fermentation of lignocellulosic biomass to ethanol may be more economical than fermentation of corn grain. However, relative to conventional fermentation processes, gasification-fermentation technology is in its infancy. It remains to be seen if the technology will be technically feasible on a commercial scale.

Cultivating citizenship and participation through culture : the use of participatory planning methods for community based watershed management in Santo Andre, Brazil
Creators: name: Saad, Layla
Publisher: name: University of British Columbia
Year: 2009

description: Adopting a participatory planning approach to community development has increasingly been placed on the agenda of governments, international development agencies and various non-governmental organisations. The interactive participation component of participatory planning processes can provide a pedagogical forum of informal education and knowledge sharing amongst local citizens and planners. The mutual social learning that is produced creates new meaning that contains both planner and citizen perspectives and knowledge. The presence and participation of citizens in participatory project activities can strengthen and/or establish notions of citizenship that can subsequently stimulate future community activism and mobilisation. This thesis will illustrate how culture, as both a creative practice and a way of life, provides a valuable instrument for community participation. The role of culture as a participatory tool is analysed for its potential in the construction of active citizenship, and as a method that facilitates the expression of local knowledge. Since putting the ideals of participation into practice is difficult, the specific purpose of this thesis is to identify and document some of the opportunities and constraints to providing creative channels of participation. This study is situated in the Municipality of Santo Andre, Brazil, where a Community Based Watershed Management (CBWM) project is currently unfolding. A series of key informant interviews and participant observation provided insight on the Brazilians' perspective of the objectives of participation, the role that culture plays in participatory planning and the several opportunities and constraints to adopting innovative forms of participation. The resulting analysis reveals issues found at the community, community/municipal and municipal (institutional) levels where a combination of distinct perceptions of participation, approaches to culture, democratisation of planning information, influences of historical and contemporary socio-political structures, technocratic practices, multi-disciplinarity, and attitudes regarding active citizenship and municipal co-management, both facilitate and complicate conditions for innovative participatory planning.

description: A resurgence of interest in multiple hypothesis testing has occurred in the last decade. Motivated by studies in genomics, microarrays, DNA sequencing, drug screening, clinical trials, bioassays, education and psychology, statisticians have been devoting considerable research energy in an effort to properly analyze multiple endpoint data. In response to new applications, new criteria and new methodology, many ad hoc procedures have emerged. The classical requirement has been to use procedures which control the strong familywise error rate (FWE) at some predetermined level α. That is, the probability of any false rejection of a true null hypothesis should be less than or equal to α. Finding desirable and powerful multiple test procedures is difficult under this requirement. One of the more recent ideas is concerned with controlling the false discovery rate (FDR), that is, the expected proportion of rejected hypotheses which are, in fact, true. Many multiple test procedures do control the FDR. A much earlier approach to multiple testing was formulated by Lehmann [Ann. Math. Statist. 23 (1952) 541-552 and 28 (1957) 1-25]. Lehmann's approach is decision theoretic and he treats the multiple endpoints problem as a 2^k finite action problem when there are k endpoints. This approach is appealing since unlike the FWE and FDR criteria, the finite action approach pays attention to false acceptances as well as false rejections.

description: With the continuing controversy over genetically modified (GM) foods, some groups advocate mandatory labeling of these products, while other groups oppose labeling. An important issue is how GM labels affect consumers' willingness to pay for these food products in the market. Using a statistically based economics experiment with adult consumers as subjects, we examine how willingness to pay changes for three food products--vegetable oil, tortilla chips, and potatoes--when GM labels are introduced. Participants in the experiments discounted GM-labeled foods by approximately 14% relative to their standard-labeled counterparts. The evidence also showed that sequencing of food labels affects willingness to pay, and that randomizing treatments is an important methodological feature in experiments of willingness to pay.

description: The objective of this paper is to synthesize the digital interventions initiatives to fight against COVID-19 in Bangladesh and compare with other countries. In order to obtain our research objective, we conducted a systematic review of the online content. We first reviewed the digital interventions that have been used to fight against COVID-19 across the globe. We then reviewed the initiatives that have been taken place in Bangladesh. Thereafter, we present a comparative analysis between the initiatives taken in Bangladesh and the other countries. Our findings show that while Bangladesh is capable to take benefits of the digital intervention approaches, tighter cooperation between government and private organizations as well as universities would be needed to get the most benefits. Furthermore, the government needs to make sure that the privacy of its citizens are protected.
