Research Thesis for Undergraduate Engineering Programs in the Digitalization Era: Learning Strategies and Responsible Research Conduct Road to a University Education 4.0 Paradigm

Many university students have doubts about how or where to start writing their undergraduate thesis work; it is common not to be clear how to identify a research problem or even towards which topic their research is oriented, and there are doubts about how to process and systematize so much information available in the era of digitalization. This article presents learning strategies to formulate a research thesis for engineering undergraduate programs, with an emphasis on the use of information and communication technologies (ICTs) toward a University Education 4.0 paradigm. The main themes and issues discussed in this article, carried out through learning strategies for students based on the scientific method, are the following: (i) Recommendations for choosing a research topic, (ii) Guidelines for problem identification and question research, (iii) Suggestions for choosing a thesis advisor, (iv) Instructions for finding suitable sources of information, (v) Structure of the table of contents for writing the thesis manuscript, and (vi) Indications for preparing an oral defense of thesis research. This article highlights recommendations and precautions directed towards professors and students with the use of the chatbot-type artificial intelligence (AI) tool called ChatGPT for the formulation of the thesis under a responsible conduct approach in research. This article concludes that the application of tutoring/guidance strategies between professors and students requires an adequate ethical use of information and communication technologies (ICTs) during the development of a research thesis to generate a comprehensive educational environment that encourages research and develops a sustainable learning process in the context of the University Education 4.0 paradigm

The 3D inelastic analysis methods for hot section components

Advanced 3-D inelastic structural/stress analysis methods and solution strategies for more accurate and yet more cost-effective analysis of combustors, turbine blades, and vanes are being developed. The approach is to develop four different theories, one linear and three higher order with increasing complexities including embedded singularities. Progress in each area is reported

A duality principle for the multi-block entanglement entropy of free fermion systems

The analysis of the entanglement entropy of a subsystem of a one-dimensional quantum system is a powerful tool for unravelling its critical nature. For instance, the scaling behaviour of the entanglement entropy determines the central charge of the associated Virasoro algebra. For a free fermion system, the entanglement entropy depends essentially on two sets, namely the set A of sites of the subsystem considered and the set K of excited momentum modes. In this work we make use of a general duality principle establishing the invariance of the entanglement entropy under exchange of the sets A and K to tackle complex problems by studying their dual counterparts. The duality principle is also a key ingredient in the formulation of a novel conjecture for the asymptotic behavior of the entanglement entropy of a free fermion system in the general case in which both sets A and K consist of an arbitrary number of blocks. We have verified that this conjecture reproduces the numerical results with excellent precision for all the configurations analyzed. We have also applied the conjecture to deduce several asymptotic formulas for the mutual and r-partite information generalizing the known ones for the single block case

Cortisol and testosterone increase financial risk taking and may destabilize markets

It is widely known that financial markets can become dangerously unstable, yet it is unclear why. Recent research has highlighted the possibility that endogenous hormones, in particular testosterone and cortisol, may critically influence traders’ financial decision making. Here we show that cortisol, a hormone that modulates the response to physical or psychological stress, predicts instability in financial markets. Specifically, we recorded salivary levels of cortisol and testosterone in people participating in an experimental asset market (N = 142) and found that individual and aggregate levels of endogenous cortisol predict subsequent risk-taking and price instability. We then administered either cortisol (single oral dose of 100 mg hydrocortisone, N = 34) or testosterone (three doses of 10 g transdermal 1% testosterone gel over 48 hours, N = 41) to young males before they played an asset trading game. We found that both cortisol and testosterone shifted investment towards riskier assets. Cortisol appears to affect risk preferences directly, whereas testosterone operates by inducing increased optimism about future price changes. Our results suggest that changes in both cortisol and testosterone could play a destabilizing role in financial markets through increased risk taking behaviour, acting via different behavioural pathways.This work was supported by the Economic and Social Research Council (grant ES/G005230/1).

Density functional theory embedding for correlated wavefunctions: Improved methods for open-shell systems and transition metal complexes

Density functional theory (DFT) embedding provides a formally exact framework for interfacing correlated wave-function theory (WFT) methods with lower-level descriptions of electronic structure. Here, we report techniques to improve the accuracy and stability of WFT-in-DFT embedding calculations. In particular, we develop spin-dependent embedding potentials in both restricted and unrestricted orbital formulations to enable WFT-in-DFT embedding for open-shell systems, and we develop an orbital-occupation-freezing technique to improve the convergence of optimized effective potential (OEP) calculations that arise in the evaluation of the embedding potential. The new techniques are demonstrated in applications to the van-der-Waals-bound ethylene-propylene dimer and to the hexaaquairon(II) transition-metal cation. Calculation of the dissociation curve for the ethylene-propylene dimer reveals that WFT-in-DFT embedding reproduces full CCSD(T) energies to within 0.1 kcal/mol at all distances, eliminating errors in the dispersion interactions due to conventional exchange-correlation (XC) functionals while simultaneously avoiding errors due to subsystem partitioning across covalent bonds. Application of WFT-in-DFT embedding to the calculation of the low-spin/high-spin splitting energy in the hexaaquairon(II) cation reveals that the majority of the dependence on the DFT XC functional can be eliminated by treating only the single transition-metal atom at the WFT level; furthermore, these calculations demonstrate the substantial effects of open-shell contributions to the embedding potential, and they suggest that restricted open-shell WFT-in-DFT embedding provides better accuracy than unrestricted open-shell WFT-in-DFT embedding due to the removal of spin contamination.Comment: 11 pages, 5 figures, 2 table

Peak oil: will it be public health's greatest challenge?

The health of populations is determined more by the social and economic determinants of health than by changes in technology, health services or short-term policy interventions. In the near future, there is likely to be a significant shortfall in energy supply, resulting in high energy prices and a reversal of many of the aspects of globalization that are currently taken for granted. If this happens, economic recession and restructuring could have a negative impact on health, not dissimilar to that experienced by the former Soviet Union when it attempted a rapid change in its economy. There is, however, the potential, through economic planning and sustainable development, to reduce the adverse effects of this change and use this opportunity to impact on a range of diseases which are, at least in part, caused by overconsumption, inequality and loss of community

Subsistence food production and marketing in Papua New Guinea : a research paper presented in partial fulfilment of the requirements for the degree of Master in Philosophy in Development Studies at Massey University

Agriculture is the main component of the economic sector of the Less Developed Countries (LDC's) of Asia, Africa and Latin America. In most of these countries, which includes Papua New Guinea (PNG), subsistence agriculture dominates despite the tremendous advances in agricultural technology elsewhere, especially in Developed Countries, in the course of the twentieth century. The characteristic feature of these subsistence farms is low productivity which means small, if any, production surplus over consumption, which results in very little trade between the agriculture sector and other sectors of the country. In LDC's, this has often led to declining food production and increased dependence on imported food as the bulk of domestic food supply is produced by the subsistence sector. In PNG, very similar trends are noted. This paper examines some issues affecting smallholder agriculture and implications for increasing agricultural productivity in PNG. Specifically, the research problem and the focus of this study is firstly, how to increase subsistence food production and secondly, how to effectively move the rural surplus to urban consumers where it is required. To increase productivity, LDC's are faced with two choices; extend land area under cultivation if land is available or improve agricultural technology if land is scarce. While PNG is relatively well endowed with land (more than four times the average for developing countries) , much of the land is too mountainous to convert to arable land, with only less than 0.3 per cent of the land used for annual crops and grazing. The choice of strategy thus is determined by land. This paper shows that the PNG government has under-invested in agriculture, particularly subsistence agriculture. Further investment in research and technology is required, focusing especially on their farming systems. Traditional farmers are not traditionalist by choice. Agricultural techniques have been developed over centuries, through years of accumulated experience of generations of farmers. Extensive literature in agriculture economics show that traditional farmers cannot normally adopt technological innovations unless the circumstances in which they operate are first changed. The important role of marketing in economic development is also underplayed. It is a common fallacy to assume that markets when left to their own devices can lead to increased productivity and efficiency within the distribution system. Government intervention is also necessary in marketing to achieve social goals of self sufficiency in food production. This study attempts to demonstrate that given the right incentives, mostly institutional and technological, subsistence food production can be increased in PNG

An Analysis Of Gateway Programs On African American Student Retention: A Case Study In An Urban Higher Education Setting

ABSTRACT AN ANALYSIS OF GATEWAY PROGRAMS ON AFRICAN AMERICAN STUDENT RETENTION: A CASE STUDY IN AN URBAN HIGHER EDUCATION SETTING by JANICE COOK JOHNSON MAY 2017 Advisor: Dr. Carolyn Muriel Shields Major: Educational Leadership and Policy Studies Degree: Doctor of Philosophy Existing policies and processes have not gone far enough to eradicate the persistent academic achievement gap at Wayne State University. Nor has identifying poor student academic preparation prior to enrollment. By accepting this reality and responsibility, officials and members within the university community can affect change, bringing parity to retention through graduation, by becoming proficient at serving the students it enrolls. This study unearthed some biases regarding student progression by treatment programs. White students were more likely to enroll at the university through the Honors program. These students traditionally performed high on academic measurement indices. Conversely, African American students were more likely to enroll at the university through an alternative admissions program such as TRiO or DCE whose mission was to support under-served often low-income and first generation students. So why then, does the institution compare the progress of Honor students with deficit enrollment students? Another bias was in the process in which African American students enrolled at the university. This research found that 37.78 percent of African American students enrolled though a gateway program and that those students comprised 52.26 percent of all students in a treatment program. Moreover, the treatment programs African Americans were enrolled were deficit model programs. This was the contribution of this research. To link how those barriers pointed to how Wayne State University interacted with, provided services to, and ultimately judged the academic progress African American students were making as unsuccessful. As stated in the beginning of this research, the educational achievement gap was a by-product of a racialized society. African Americans did not become over-represented in the lower class in America because of inferior genetic makeup, nor was that the reason they were not progressing at Wayne State University. They are being removed from equal opportunity, starting their university experience behind the preparedness level of other students, and then being blamed for not being successful
