The Interpersonal Determinants of Green Purchasing: An assessment of the empirical record
No full textabstract: This study investigates how well prominent behavioral theories from social psychology explain green purchasing behavior (GPB). I assess three prominent theories in terms of their suitability for GPB research, their attractiveness to GPB empiricists, and the strength of their empirical evidence when applied to GPB. First, a qualitative assessment of the Theory of Planned Behavior (TPB), Norm Activation Theory (NAT), and Value-Belief-Norm Theory (VBN) is conducted to evaluate a) how well the phenomenon and concepts in each theory match the characteristics of pro-environmental behavior and b) how well the assumptions made in each theory match common assumptions made in purchasing theory. Second, a quantitative assessment of these three theories is conducted in which r2 values and methodological parameters (e.g., sample size) are collected from a sample of 21 empirical studies on GPB to evaluate the accuracy and generalize-ability of empirical evidence. In the qualitative assessment, the results show each theory has its advantages and disadvantages. The results also provide a theoretically-grounded roadmap for modifying each theory to be more suitable for GPB research. In the quantitative assessment, the TPB outperforms the other two theories in every aspect taken into consideration. It proves to 1) create the most accurate models 2) be supported by the most generalize-able empirical evidence and 3) be the most attractive theory to empiricists. Although the TPB establishes itself as the best foundational theory for an empiricist to start from, it's clear that a more comprehensive model is needed to achieve consistent results and improve our understanding of GPB. NAT and the Theory of Interpersonal Behavior (TIB) offer pathways to extend the TPB. The TIB seems particularly apt for this endeavor, while VBN does not appear to have much to offer. Overall, the TPB has already proven to hold a relatively high predictive value. But with the state of ecosystem services continuing to decline on a global scale, it's important for models of GPB to become more accurate and reliable. Better models have the capacity to help marketing professionals, product developers, and policy makers develop strategies for encouraging consumers to buy green products.Dissertation/ThesisM.S.

Ten Years of bored tunnels in the Netherlands: Part I: Geotechnical issues
No full textTen years have passed since in 1997 for the first time construction of bored tunnels in the Netherlands soft soil was undertaken. Before that date essentially only immersed tunnels and cut-and-cover tunnels were constructed in the Netherlands. The first two bored tunnels were Pilot Projects, the 2nd Heinenoord tunnel and the Botlek Rail tunnel. Since then a series of other bored tunnels has been constructed and some are still under construction today. At the beginning of this period, amongst others Bakker et al(1997), gave an overview of the risks related to bored tunnels in soft ground and a plan for research related to the pilot projects was developed. After that in 1999 the 2nd Heinenoord tunnel opened for the public, the “Jointed platform for Bored tunnelling”, in short GPB, was organized, to coordinate further research and monitoring of bored tunnels. This platform is supervised by the Center for Underground Construction. In this paper a summary is given of some of the most characteristic observations on these 10 years of underground construction in the Netherlands. In the first part of this paper the focus is on geotechnical interactions, and stability, whereas part two will focus more on structural related issues.Hydraulic EngineeringCivil Engineering and Geoscience

Bakalaura darbā ir 53 izmantotās literatūras un avoti.The Bachelor's paper aim is a technical analysis forecasting methods of theoretical research and practical approbation for exchange rate prediction, based on research made.
In the Bachelor’s paper the trend models have been researched, moving average and oscillator applications in the currency pairs EUR / USD and GBP / USD exchange rate dynamics in forecasting an hourly schedule. The structure of the Bachelor paper is formed to complete the Bachelor’s paper tasks. Bachelor thesis made of an introduction, four chapters, conclusions and proposals, bibliography and appendices.
The first chapter is devoted to the international foreign exchange market history, a reflection of its technical characteristics, as well as influencing factors on the exchange rates were identified. The author also gave a look into the essence of technical analysis and its historical development, and offered her own definitions of technical analysis.
In the second chapter the technical analysis of graphic techniques was researched. The author described the types of graphics, and trend channel lines, and the trend changes and follow-up of images, providing the most graphic examples of methods and made the own statistics for the period from August 2009 to May 2012.
The Bachelor paper in the third section describes the most popular technical analysis tools - moving average and oscillators. The author has described the history of technical analysis tools, principles of operation and the provision of their trading signals.
To achieve the goal, in the fourth chapter the author carried out in the second and the third chapters investigated technical analysis tools using the EUR/USD and GBP/USD rate dynamics prediction, based on made research.
During the exchange rate of EUR/USD and GBP/USD dynamic forecasting, using technical analysis in real time, the author concluded that technical analysis can accurately predict the direction of exchange rate fluctuations, but it is not possible to predict the exact exchange rate value. The author concluded that in order to predict the exchange rate dynamics there is not sufficient to use only one, though a strong individual technical analysis method because of several technical analysis indicators signals reinforces the uniform estimate.
The Bachelor paper concludes of 73 pages, 25 images, 3 tables and 22 appendices.

The Heterodimeric Glycoprotein Hormone, GPA2/GPB5, Regulates Ion Transport across the Hindgut of the Adult Mosquito, Aedes aegypti
No full textA family of evolutionarily old hormones is the glycoprotein cysteine knot-forming eterodimers consisting of alpha- (GPA) and beta-subunits (GPB), which assemble by noncovalent bonds. In mammals, a common glycoprotein hormone alphasubunit
(GPA1) pairs with unique beta-subunits that establish receptor specificity, forming thyroid stimulating hormone (GPA1/TSHb) and the gonadotropins luteinizing hormone GPA1/LHb), follicle stimulating hormone (GPA1/FSHb), choriogonadotropin (GPA1/CGb). A novel glycoprotein heterodimer was identified in vertebrates by genome analysis,
called thyrostimulin, composed of two novel subunits, GPA2 and GPB5, and homologs occur in arthropods, nematodes and cnidarians, implying that this neurohormone system existed prior to the emergence of bilateral metazoans. In order to discern possible physiological roles of this hormonal signaling system in mosquitoes, we have isolated the glycoprotein hormone genes producing the alpha- and beta-subunits (AedaeGPA2 and AedaeGPB5) and assessed their temporal expression profiles in the yellow and dengue-fever vector, Aedes aegypti. We have also isolated a putative receptor for this novel mosquito hormone, AedaeLGR1, which contains features conserved with other glycoprotein leucine-rich repeating containing G protein-coupled receptors. AedaeLGR1 is expressed in tissues of the alimentary canal such as the midgut,
Malpighian tubules and hindgut, suggesting that this novel mosquito glycoprotein hormone may regulate ionic and osmotic balance. Focusing on the hindgut in adult stage A. aegypti, where AedaeLGR1 was highly enriched, we utilized the Scanning Ion-selective Electrode Technique (SIET) to determine if AedaeGPA2/GPB5 modulated cation transport across this epithelial tissue. Our results suggest that AedaeGPA2/GPB5 does indeed participate in ionic and osmotic balance, since it appears to inhibit natriuresis and promote kaliuresis. Taken together, our findings imply this hormone may play an
important role in ionic balance when levels of Na+ are limited and levels of K+ are in excess – such as during the digestion and assimilation of erythrocytes following vertebrate blood-feeding by females.This research was supported through an NSERC postdoctoral fellowship to J.P.P. and an NSERC Discovery Grant and Discovery Accelerator Supplement to MJO.

A Critical Review on the Use of Molecular Imprinting for Trace Heavy Metal and Micropollutant Detection
No full textMolecular recognition has been described as the “ultimate” form of sensing and plays a fundamental role in biological processes. There is a move towards biomimetic recognition elements to overcome inherent problems of natural receptors such as limited stability, high-cost, and variation in response. In recent years, several alternatives have emerged which have found their first commercial applications. In this review, we focus on molecularly imprinted polymers (MIPs) since they present an attractive alternative due to recent breakthroughs in polymer science and nanotechnology. For example, innovative solid-phase synthesis methods can produce MIPs with sometimes greater affinities than natural receptors. Although industry and environmental agencies require sensors for continuous monitoring, the regulatory barrier for employing MIP-based sensors is still low for environmental applications. Despite this, there are currently no sensors in this area, which is likely due to low profitability and the need for new legislation to promote the development of MIP-based sensors for pollutant and heavy metal monitoring. The increased demand for point-of-use devices and home testing kits is driving an exponential growth in biosensor production, leading to an expected market value of over GPB 25 billion by 2023. A key requirement of point-of-use devices is portability, since the test must be conducted at “the time and place” to pinpoint sources of contamination in food and/or water samples. Therefore, this review will focus on MIP-based sensors for monitoring pollutants and heavy metals by critically evaluating relevant literature sources from 1993 to 2022.Bio-Electronic
Constraining gravitational and cosmological parameters with astrophysical data
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2008.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 189-199).We use astrophysical data to shed light on fundamental physics by constraining parametrized theoretical cosmological and gravitational models. Gravitational parameters are those constants that parametrize possible departures from Einstein's general theory of relativity (GR). We develop a general framework to describe torsion in the space time around the Earth, and show that certain observables of the Gravity Probe B (GPB) experiment can be computed in this framework. We examine a toy model showing how a specific theory in this framework can be constrained by GPB data. We also search for viable theories of gravity where the Ricci scalar R in the Lagrangian is replaced by an arbitrary function f(R). Making use of the equivalence between such theories and scalar-tensor gravity, we find that models can be made consistent with solar system constraints either by giving the scalar a high mass or by exploiting the so-called Chameleon Effect. We explore observational constraints from the late-time cosmic acceleration, big bang nucleosynthesis and inflation. Cosmology can successfully describe the evolution of our universe using six or more adjustable cosmological parameters. There is growing interest in using 3-dimensional neutral hydrogen mapping with the redshifted 21 cm line as a cosmological probe. We quantify how the precision with which cosmological parameters can be measured depends on a broad range of assumptions. We present an accurate and robust method for measuring cosmological parameters that exploits the fact that the ionization power spectra are rather smooth functions that can be accurately fit by 7 phenomenological parameters. We find that a future square kilometer array optimized for 21 cm tomography could have great potential, improving the sensitivity to spatial curvature and neutrino masses by up to two orders of magnitude, to k 0.0002 and m 0.007eV, and giving a 4s detection of the spectral index running predicted by the simplest inflation models.by Yi Mao.Ph.D
ANTIBIOTIC RESISTANCE PROFILE OF ISOLATED BACTERIA AT THE SANGMELIMA REFERENCE HOSPITAL, SOUTH CAMEROON REGION: A RETROSPECTIVE STUDY
No full textBackground and objective: Bacterial resistance to antibiotics is now one of the most serious threats to global health. Knowledge of the main bacterial species responsible for bacteremia and their antibiotic resistance profile makes possible to provide an objective basis for effective antibiotic therapy. However, in the South Cameroon region, microbiological documentation is not always available. The objective of our study was to determine the resistance profile of bacteria isolated at the Sangmélima Reference Hospital.
Methods: It was a retroprospective study on biological samples collected from interned and ambulatory patients seen at the Sangmélima Reference Hospital during the period from January 2021 to October 2021.The samples were cultured on specific media and the susceptibility was carried out on agar media using Kirby-Bauertechnique and interpretation according to the 2020 CASFM Guidelines.
Results: For the retrospective part, GNB were most represented (15/26; 57.7%,) with the E. coli (n=12/15) and only Staphylococcus spp for GPB (n=11/26). Staphylococcus resistance was particularly relevant with 81.81% to erythromycin, 63.63% to cefoxitin and 72.72% to Cotrimoxazole. E. coli showed a resistance of 66.66% for augmentin and 83.33% for cefuroxime. In the prospective part, GPB were only represented by Staphylococcus epidermidis (7/7 ; 50%), and GNB included E. coli (3/7 ; 21.42%), K. pneumoniae (2/7; 14.29%) and A baumannii (2/7; 14.29%). For all isolated bacteria strains, a high resistance to the majority of betalactams and penicillin was observed. However, bacteria with greater antibiotic resistance were Staphylococcus strains, highly resistant to beta-lactams, while A. baumannii strains showed higher resistance, and E. coli especially to penicillins and fluoroquinolones.
Conclusion: E. coli and Staphylococcus spp were predominant isolated bacteria with high rate of resistance to antibiotics frequently used in hospital. Strict adherence to infection prevention practices and judicious use of antibiotics are recommended to slow te spread of antimicrobial resistance (AMR).
