Products of Counterfactual Imagination:The Healing Life of Literature

My papers investigates two of the latter volumes by Romanian author Monica Pillat, Invitație la vis (An Invitation to Dream, 2014), and Croitorul de cărți (The Book Tailor, 2019), in which the literary experience elevates and transcends life itself, as a form of rewriting/healing the past and, maybe, of projecting one’s dreams into the future. It relies on criticism of two stories from the respective volumes, which investigates the sites of memory, such as the family mansion, which is the central piece around which the fantasy world woven by the author gravitates. Since Monica Pillat descends from a whole line of literary masters, her gift for writing is in fact a form of recuperating and also compensating for the family past, in which especially her father (Dinu Pillat) was very much afflicted by political persecution during Communist times. In my paper, I will dwell upon the less factual connection between life and literature – that of a mutual mirroring and influencing – in the attempt to prove that the experience of writing can make up for the losses encountered in reality. In this sense, being a literary author may offer one the chance of re-inventing one’s self (or imaginatively amending the life of your loved ones) and – for Monica Pillat – it certainly offers the greatest reward of all: a continual dwelling inside the family lineage, in the company of the kindred spirits that have guided and protected her since she was born.

Evaluating the effectiveness of the EU’s approach to the sustainable use of pesticides

By adopting the 2009 "pesticide package," the EU proposed a common approach to limiting the harmful effects of pesticides, promoting Integrated Pest Management, and the progressive replacement of the most dangerous pesticides with low-risk alternatives through a comprehensive but flexible framework for all EU Member States. Each EU Member State had to develop a National Action Plan that would propose measures to achieve the package’s goals. Nevertheless, the choice of actions and indicators remained to be established at the national level. A series of recent evaluations of how Directive 2009/128/EC of the European Parliament and the Council on the Sustainable Use of Pesticides Directive (SUD), a central piece of the "pesticide package," was implemented showed limited success in achieving its goals. Aiming to explain these failures, we compare the National Action Plans eight EU Member States adopted after the SUD. We assess the degree to which the countries’ proposed measures and indicators would achieve the Directive’s three overarching objectives (reduce risks and impact; promote Integrated Pest Management; promote approaches and techniques to reduce reliance on pesticides). We develop the comparative analysis along three dimensions: the promotion of measures to achieve SUD’s three goals; the evolution of the pre-and post-Directive action plans of some of the old EU Member States; and the differences between old and the new EU Member States. The comparison along ten variables shows that the SUD had a minimal effect in homogenizing different states’ approaches to develop their National Action Plans to systematically treat problems, propose measures, and timetables for implementation and indicators. Given that the overall effect in generating a common EU approach to raise the sustainability of pesticide use and agriculture, in general, was still limited, as no common measures, indicators, or process to planning were identified, we discuss some suggestions to improve the situation.

Generalization Second Order Macroscopic Traffic Models via Relative Velocity of the Congestion Propagation

This paper presents a generalized second-order hydrodynamic traffic model. Its central piece is the expression for the relative velocity of the congestion (compression wave) propagation. We show that the well-known second-order models of Payne–Whitham, Aw–Rascal and Zhang are all special cases of the featured generalized model, and their properties are fully defined by how the relative velocity of the congestion is expressed. The proposed model is verified with traffic data from a segment of the Interstate 580 freeway in California, USA, collected by the California DOT’s Performance Measurement System (PeMS).

BlueFMCW: Random Frequency Hopping Radar for Mitigation of Interference and Spoofing

Radars form a central piece in a variety of emerging applications requiring higher degrees of localization. However, two problems are anticipated as more radars are deployed: viz., (i) inter-radar interference and (ii) security attacks. While many prior proposals have addressed the problems, no work in the radar literature addressed them simultaneously. In this context, we introduce a novel frequency-modulated continuous-wave (FMCW) radar scheme (namely, BlueFMCW) that aims to alleviate the damage from interference and active attacks (e.g., spoofing). The technique designs that the waveform randomly hops across multiple frequencies to dilute the damage at a certain frequency. Moreover, we propose a phase alignment algorithm to remove the phase discontinuity while combining the beat signals from the randomly-hopped chirps. The simulation results show that the proposed technique can efficiently mitigate the interference and spoofing signals in various scenarios without costing its resolution.

Business Law

Business Law provides practical, up-to-date coverage of company, partnership, taxation, and insolvency law, plus all relevant aspects of EU law. The title provides all of the relevant material needed to understand the latest legal developments affecting business law transactions. Coverage of the Companies Act 2006 is fully integrated and given prominence, mirroring the emphasis that business law courses place on this central piece of legislation. Additional emphasis has been placed on taxation and business accounts. Examples are used throughout the volume, which helps readers to contextualise their learning effectively. Updated statutory references allow for the cross-referencing to appropriate primary sources, and the interpretation of such sources. The volume looks at partnerships, companies, taxation, insolvency, and other topics such as choice of business medium, limited liability partnerships, sale of a business, and shareholder agreements.

Change by challenge: A common genetic basis behind childhood cognitive development and cognitive training

The interplay of genetic and environmental factors behind cognitive development has preoccupied multiple fields of science and sparked heated debates over the decades. Here we tested the hypothesis that developmental genes rely heavily on cognitive challenges—as opposed to natural maturation. Starting with a polygenic score (cogPGS) that previously explained variation in cognitive performance in adults, we estimated its effect in 344 children and adolescents (mean age of 12 years old, ranging from 6 to 25) who showed changes in working memory (WM) in two distinct samples: (1) a developmental sample showing significant WM gains after 2 years of typical, age-related development, and (2) a training sample showing significant, experimentally-induced WM gains after 25 days of an intense WM training. We found that the same genetic factor, cogPGS, significantly explained the amount of WM gain in both samples. And there was no interaction of cogPGS with sample, suggesting that those genetic factors are neutral to whether the WM gains came from development or training. These results represent evidence that cognitive challenges are a central piece in the gene-environment interplay during cognitive development. We believe our study sheds new light on previous findings of interindividual differences in education (rich-get-richer and compensation effects), brain plasticity in children, and the heritability increase of intelligence across the lifespan.

Mechanical Design

This chapter discusses various mechanical designs for STM and AFM. The central piece of the mechanical design of STM and AFM is the course positioner. Therefore, various types of course positioners are also discussed. The louse and the pocket-size STM are discussed first. It is of significant historical importance but no longer popular today. The single-tube STM has a very simple mechanical structure, and still the basis of the most popular commercial STM and AFM. The Besocke-type or the beetles is very popular among builders of special-purpose STM due its immunity to temperature variation and vibration. For STM requiring superb stability, the walker and the kangaroo are the preferred design. The commercial nanostepper, the Inchworm, is described. It has been successfully used by many designers of special-purpose STM.

Raising College Access and Completion: How Much Can Free College Help?

Free college proposals have become increasingly popular in many countries of the world. To evaluate their potential effects, we develop and estimate a dynamic model of college enrollment, performance, and graduation. A central piece of the model, student effort, has a direct effect on class completion, and an indirect effect in mitigating the risk of not completing a class or not remaining in college. We estimate the model using rich, student-level administrative data from Colombia, and use the estimates to simulate free college programs that differ in eligibility requirements. Among these, universal free college expands enrollment the most, but it does not affect graduation rates and has the highest per-graduate cost. Performance-based free college, in contrast, delivers a slightly lower enrollment expansion yet a greater graduation rate at a lower per-graduate cost. Relative to universal free college, performance-based free college places a greater risk on students but is precisely this feature that delivers better outcomes. Nonetheless, the modest increase in graduation rates suggests that additional, complementary policies might be required to elicit the large effort increase needed to raise graduation rates.

DSurvey: A Blockchain-Enhanced Survey Platform for the Data Economy

The data economy is predicted to boom and become a 156B dollars business by 2025. In this demo we introduce the use of distributed ledger technologies (DLT) applied to digital surveys in order to create an ecosystem where data becomes a central piece of a complex economy. Our system allows for interesting key features; ownership, traceability, secure profiles, and anonymity where required. Also, the most important feature, is the incentive mechanism that rewards all participants, both users creating surveys and those answering the surveys. DSurvey (decentralized survey) is a novel application framework that aims at moving away from the large commercial data sink paradigm whose business is restricted to gathering data and reselling it. Our solution makes so that no central data sink exists, and it always belongs to the creator, who are able to know who is using it, and receive royalties.

Using the QFD Matrix as a Major Continuous Improvement Tool to Improve Organizational Quality

This is a case study of an Australian higher education institution (HEI) using quality function deployment (QFD) to identify areas of improvement in serving and meeting the needs of international students enrolled at this university. The composite institution reflects what is currently happening at the time of this writing as part of a process of determining international student needs and ensuring that these are met while meeting academic and institutional requirements (IR). The use of QFD fills a major gap since most methodologies practiced do not focus on either capturing the international students' voice or align these with IRs to enhance the opportunities for successful completion of a degree and meeting student personal and professional expectations. Results are incomplete at this time and thus cannot be reported, but a discussion of the approach is provided, and initial observations are presented to adequately describe the use of QFD and processes and tools used to complete different parts are the central piece of the process, the house of quality (HoQ).
