Experimental testing and model validation of a decoupled-phase on-load tap-changer transformer in an active network

Owing to the increasing penetration of single-phase small generation units and electric vehicles connected to distribution grids, system operators are facing challenges related to local unbalanced voltage rise or drop issues, which may lead to a violation of the allowed voltage band. To address this problem, distribution transformers with on-load tapping capability are under development. This study presents model and experimental validation of a 35 kVA three-phase power distribution transformer with independent on-load tap-changer control capability on each phase. With the purpose of investigating and evaluating its effectiveness under different operative conditions, appropriate scenarios are defined and tested considering both balanced and unbalanced situations, also in case of reverse power flow. The experimental setup is built starting from an analysis of a Danish distribution network, in order to reproduce the main feature of an unbalanced grid. The experimental activities are recreated in by carrying out dynamics simulation studies, aiming at validating the implemented models of both the transformer as well as the other grid components. Phase–neutral voltages’ deviations are limited, proving the effectiveness of the phase-independent tap operations. Furthermore, minor deviations of the results from simulations and experiments confirm that all the system components have been properly modelled.
SEEKING ADEQUATE COMPENCIES FOR THE FUTURE:

Digital skills are a prerequisite today for working, studying, civic participation, and maintaining social relationships in our digitalised technical world. These skills are also important both as a general goal and an instrument for learning. This study briefly presents the aims that are related to digital skills of the Finnish curricula, and explores, using a large sample (N = 3,206) of Finnish upper secondary school students, these young people’s digital skills and their distribution. The study provides new insights into the state of these skills and differences found in them and focuses on the relationship between these results and the students’ present educational choices and future study/employment intentions. The actual variability of digital skills among upper secondary students is one of the main findings of the study. On the same educational level, it was found that digital skills vary enormously, particularly for students’ current educational choices and their future intentions. Digital skills are also distinctly associated with age for 15 to 22-yearolds. At the same time, gender alone appears to have no prominent effect on the level or adeptness of upper secondary school students’ digital skills.
Inter-group entrainment in Afro-Brazilian Congado ritual

This paper investigates the phenomenon of entrainment between independent groups of musicians in the context of Afro-Brazilian Congado performance. Based on audiovisual recordings made during a festival in May 2006, we present analyses of four different occasions during which two different groups play different music in close proximity to each other. The results indicate the occurrence of (a) entrainment in phase, (b) entrainment out of phase, and (c) no entrainment. These results are discussed in the particular ethnographic context, as well as with reference to existing literature on entrainment and interpersonal coordination.

Mock weak lensing analysis of simulated galaxy clusters: bias and scatter in mass and concentration

We quantify the bias and scatter in galaxy cluster masses M200 and concentrations c derived from an idealised mock weak gravitational lensing (WL) survey, and their effect on the cluster mass-concentration relation. For this, we simulate WL distortions on a population of background galaxies due to a large (≈ 3000) sample of galaxy cluster haloes extracted from the Millennium Simulation at z ≃ 0.2. This study takes into account the influence of shape noise, cluster substructure and asphericity as well as correlated large-scale structure, but not uncorrelated large-scale structure along the line of sight and observational effects (e.g., the source redshift distribution and measurement, and measurement of galaxy ellipticities). We find a small, but non-negligble, negative median bias in both mass and concentration at a level of ∼ 5%, the exact value depending both on cluster mass and radial survey range. Both the mass and concentration derived from WL show considerable scatter about their true values. This scatter has, even for the highest mass clusters of M200 > 1014.8M⊙, a level of ∼ 30% and ∼ 20% for concentration and mass respectively and increases strongly with decreasing cluster mass. For a typical survey analysing 30 galaxies per arcmin2 over a radial range from 30′′ to 15′ from the cluster centre, the derived M200-c relation has a slope and normalisation too low compared to the underlying true (3D) relation by ∼ 40% and ∼ 15% respectively. The scatter and bias in mass are shown to reflect a departure at large radii of the true WL shear/matter distribution of the simulated clusters from the NFW profile adopted in modelling the mock observations. Orientation of the triaxial cluster haloes dominates the concentration scatter (except at low masses, where galaxy shape noise becomes dominant), while the bias in c is mostly due to substructure within the virial radius.
SEQUENCES OF NONLINEAR CONTRACTIONS AND STABILITY OF FIXED POINTS

Stability of fixed points for sequences of nonlinear contractions over a variable domain is studied in a 2-metric space. The results so obtained generalize some recent results of Mishra et al. [Chaos, Soliton & Fractals 45(2012), 1012-1016] and Barbet and Nachi [Monografias del Seminario Matematico Garcia de Galdeano 33(2006), 51--58].
A NATURAL ACCOUNT OF PHENOMENAL CONSCIOUSNESS.

Physicalists commonly argue that conscious experiences are nothing more than states of the brain, and that conscious qualia are observer-independent, physical properties of the external world. Although this assumes the ‘mantle of science,’ it routinely ignores the findings of science, for example in sensory physiology, perception, psychophysics, neuropsychology and comparative psychology. Consequently, although physicalism aims to naturalise consciousness, it gives an unnatural account of it. It is possible, however, to develop a natural, nonreductive, reflexive model of how consciousness relates to the brain and the physical world. This paper introduces such a model and how it construes the nature of conscious experience. Within this model the physical world as perceived (the phenomenal world) is viewed as part of conscious experience not apart from it. While in everyday life we treat this phenomenal world as if it is the "physical world", it is really just one biologically useful representation of what the world is like that may differ in many respects from the world described by physics. How the world as perceived relates to the world as described by physics can be investigated by normal science (e.g. through the study of sensory physiology, psychophysics and so on). This model of consciousness appears to be consistent with both third-person evidence of how the brain works and with first-person evidence of what it is like to have a given experience. According to the reflexive model, conscious experiences are really how they seem.
2. Midgley.p65

It is usually assumed in debates about complexity and the philosophy of science that science is primarily about observation. However, the starting point for this paper is intervention, defined as purposeful action by an agent to create change. While some authors suggest that intervention and observation are opposites, it is argued here that observation (as undertaken in science) should be viewed as just one type of intervention. We should therefore welcome scientific techniques of observation into a pluralistic set of intervention methods, alongside methods for exploring values, reflecting on subjective understandings, planning future activities, etc. However, there is a need to explicitly counter a possible pernicious interpretation of this argument: intervention could (erroneously) be viewed as flawlessly pre-planned change based on accurate predictions of the consequences of action. This is the mechanistic worldview that systems thinking and complexity science seek to challenge. Therefore, having redefined scientific observation as intervention, the paper revisits insights from systems thinking and complexity to propose a methodology of systemic intervention. Some brief reflections are then provided on the wider social implications of this methodology.
Effectiveness of presumptive tax system in Zimbabwe: Case of ZIMRA Region one

The research’s main thrust was to evaluate the effectiveness of the presumptive tax system in Zimbabwe, case study –Zimra Region One. The research looked at the implementation of the tax head, setting of tax rates, collection of revenue and the views of various stakeholders. In this study 100 ZIMRA staff members, 180 informal traders and 20 local authority staff members formed the main research participants. It was established that the presumptive tax head has not been fully implemented and administered. This has seen it contributing 60% to the gross domestic product against a 3% contribution to revenue compared with other tax heads. The principal findings were that many players in the informal sector are oblivious of the existence and objective of the presumptive tax head. In addition, the absence of involvement of the concerned stakeholders in determining tax rates has resulted in spirited resistance. ZIMRA has its own shortcomings which include lack of follow ups and inadequate awareness campaigns. The study revealed that effective implementation and administration of the tax head has the potential of increasing the revenue base. This means there is room for improvement on implementation and administering of the presumptive tax. Key words: Presumptive tax, Informal traders, Tax evasion, compliance
The Impact of Strengthening Agricultural Extension Services: Evidence from Ethiopia

This paper evaluates the effect of the Rural Capacity Building Project, which aimed at promoting growth by strengthening the agricultural service systems in Ethiopia and by making them more responsive to smallholders' needs. The project intended to increase the outreach of agricultural extension services to help farmers become aware of and adopt economically viable and environmentally sustainable technologies and practices. The paper examines the impact of the Rural Capacity Building Project using panel data on 1,485 geographically dispersed households in project and control kebeles. The results show that the strengthening of extension services had a positive impact on economic participation in the household, land area cultivated, and adoption of marketable crops, suggesting that access to extension helped farmers switch to more commercial, market-oriented agriculture. In addition, and contrary to previous evidence from other countries, female-headed households seem to have benefited equally from the project. However, the project was not able to reduce the preexisting gender gap in agricultural outcomes.
Influences of Hatchery Supplementation, Spawner Distribution, and Habitat on Genetic Structure of Chinook Salmon in the South Fork Salmon River, Idaho

Abstract We evaluated the genetic influence of hatchery supplementation on distinct naturally spawning populations of Chinook salmon Oncorhynchus tshawytscha in the South Fork Salmon River (SFSR), Idaho. Genetic tissue samples were collected from unmarked natural-origin and McCall Fish Hatchery (MFH)-reared Chinook salmon carcasses, and fish were identified by an adipose fin clip at five main-stem sites located both upstream and downstream of a seasonal exclusionary weir in the upper SFSR. We evaluated allele frequency data across 95 single-nucleotide polymorphism loci to determine the extent of genetic differentiation among collections. Genetic distance analyses and homogeneity tests indicated little subpopulation distinction in the upper SFSR. The weak overall genetic structure (global F ST = 0.010) is likely reflective of a population diversity similar to the historical structure with introgression by MFH stock in the naturally spawning population of the upper SFSR. Further analyses were conducted to e.
Cuisine and conquest: interdisciplinary perspectives on food, continuity and change in 11th-century England and beyond

Multiple strands of evidence are combined to determine the impact of the Norman Con-quest on food culture. Diet is reconstructed from the analysis of zooarchaeological, archaeobotanical and ceramic evidence, as well as through an analysis of the 12th-century text Urbanus magnus. This text is then examined alongside the study of artefacts to reconstruct practices surrounding cooking and dining. The chapter concludes that the Norman Conquest did not have a clear and consistent impact on food culture. Whilst some changes, particularly to elite cuisine, can be related to Norman influences, others, such as an increase in fish consumption, are in fact indicative of longer-term trends. It is considered that the continuities and changes observed caused different experiences of the Conquest to be mediated through food, for some allowing new forms of elite, Norman, identity to emerge, whilst for others the consumption of familiar foods provided stability in a changing world.
The Role of Gender Identities and Stereotype Salience With the Academic Performance of Male and Female College Athletes

An experiment was conducted to examine factors that moderate the experience of academic identity threat among college athletes who represent a stigmatized group on most college campuses (Yopyk & Prentice, 2005). It was hypothesized that because they are more engaged in academics, female college athletes would be especially threatened by the prospect of confirming the “dumb-jock” stereotype. As predicted, female college athletes performed more poorly when their athletic and academic identities were explicitly linked, but only on moderately difficult test items. The results also revealed that male college athletes performed significantly better (see stereotype reactance and self-affirmation) on more difficult test items when only their athletic identity was primed prior to the test. This is an important finding as there is little research on the impact of positive stereotypes on performance. The discussion focuses on the different motivational processes (i.e. self-affirmation) that impact the academic performance of male and female college athletes when aspects of their campus identity are primed within a classroom context.
Impact of school feeding programme on access to basic education: the case of South Tongu district of the Volta region, Ghana

The study examined the influence of the school feeding programme on access to basic education in the South Tongu District in the Volta Region, Ghana. Mixed method research approach was employed to conduct the study. Stratified random sampling and purposive sampling procedures were used to select 213 respondents for the study. Questionnaires and interviews were used to collect the data for the study. Data gathered through questionnaires were analysed using descriptive statistics such as percentages and frequencies while interview data analysis was done using the thematic approach. The results of the study showed that the school feeding programme has a significant influence on increased enrolment, attendance and retention of pupils in the South Tongu District. However, the implementation of the programme has put pressure on teaching and learning resources as well as increased teacher-pupil ratio. The study therefore, recommended that the government, implementation ministries and agencies should increase the existing human, physical and financial resources for the school feeding programme to be sustained.
Grain size variability as an indicator of sediment transport alongshore the Curonian Spit (south-eastern Baltic Sea)

Sediment samples have been collected along the sea coast of the Curonian Spit in summer season of 2011, 2014 and 2015-years. According to grain size analysis the shoreline and the berm consist of well and very well-sorted sand, medium-sized on the southern (Russian) part of the spit, medium and fine on the northern (Lithuanian) part. ‘McLaren’ method was applied to determine the long-shore sediment transport directions. Mismatch of results with those obtained by methods based on simulation of resulted wave action did not prove the hypothesis that ‘McLaren’ method was able to reveal long-term resulted sediment transport. The hypothesis that ‘McLaren’ method indicates the directions of alongshore sediment transport during the stormy conditions preceding the sampling period was not proved also. It was concluded that application of ‘McLaren’ method in respect of the Curonian Spit shore, which is a transit one without permanent sources or sinks of sediments, is not efficient. ‘McLaren’ method was applied to describe the cross-shore sediment movement. It was found that deposits from the trough (located between the bar and shoreline) are transported to the shoreline that is in a line with the known fact about cross-shore transport of bottom material during the calm weather.
Signaling Tax Evasion, Financial Ratios and Cluster Analysis

>> This research intends to develop a methodology for analyzing data through the use of financial indicators to classify taxpayers according the risk of possible tax evasion. We have used the data reported by companies in the years 2010 and 2011 operated in a specific sector, which is Construction Minerals Extraction and Fabrication. This study by using the Cluster Analysis intends to classify the observations into homogeneous groups according to their characteristics which suggest tax evasion. We have considered, according to recent literature, characteristics related with profitability, liquidity and activity to signal a possible manipulation of accounting data and subsequent fraudulent financial reporting. The results point out the existence of classificatory capacity in four variables. Specifically, our evidence proposes the construction of homogeneous groups which can then be used to identify companies to be tax auditing. JEL Classification: H26, C38, C81
Why Risk It? The Effect of Risk and Time Preferences on Microfinance Loan Default

Microfinance is widely recognized as a powerful method for poverty alleviation. However, little is known about the characteristics of those who default on their loans. Understanding the behavior of borrowers is an important component of mitigating adverse selection and the moral hazard of lending. Both of these concepts embody some of the greatest challenges faced by microfinance institutions, and they provide the major motivation for this study. Accordingly, the main objective of this research is to investigate whether non-delinquent borrowers and delinquent borrowers of a microfinance institution reveal any difference in their level of risk preference and time preference. This is tested through an artefactual field experiment with 97 borrowers from the National Microfinance Bank of the Hashemite Kingdom of Jordan. In the experiment, participants chose between six choices that measure their level of risk preference. In addition, participants selected a voucher that varies both in time and in value to capture their time preference levels. The results reveal that non-delinquent borrowers are more likely to be risk-seeking and impatient individuals when compared to delinquent borrowers, contradicting current literature on risk preference and time preference. I wish to thank Dr. Bruce Wydick, Dr. Alessandra Cassar, Dr. Elizabeth Katz, Dr. Yaniv Stopnitzky, Dr. Austin Boyle, Mario Javier Carrillo, Eliana Zeballos, and John Maxwell for helpful comments and input on this research, along with Eric Fischer, Amer Abunie, Dunia Aburish, Ngan Bui, Lauren Pugh, Carmen Ly, Akram Kawamleh, Abdullah Abu-alkhel, Omar Mansour, and Laith Yousef who were instrumental in collecting data and making this research possible.

Bond Structure and Tensile Properties of Thermal Bonded Polypropylene Nonwovens

Extensive studies have been conducted to investigate the effect of several process conditions on the structure and properties of nonwoven webs. As thermal point bonding is one of the most important processes, a detailed analysis of the point bond structures was done to help understand the development of tensile properties. Spunbond fabrics produced under different conditions were investigated, especially with respect to bond structure and failure mechanisms. Although bond structure does not show a big difference on microscopic observation, the way it responds during tensile deformation is dissimilar depending on the bonding temperature, leading to differences in failure mechanisms and tensile properties of the web.
