The aim of this paper was to discuss the role of food preservation science and technology in the conservation of complex food-based installations. By introducing the principles of food science and food preservation into the decision-making process for the conservation of contemporary art, more insight on conservation and presentation possibilities was created. Considering the installation Piece in Ghent (P.I.G.) by Jason Rhoades, which contains French fries, the principles of food preservation science were evaluated. The preservation of the original foods was discussed against the potential of a reproduction of the foods. The context for conservation was determined by analysing the artist's intention, the production method of the artwork, and the degradation processes of the food materials. From the results obtained, guidelines to preserve the ‘original’ foods were proposed, as well as guidelines to reproduce foods that can last longer. The study demonstrated that food preservation science contributed to the development of effective strategies for the conservation of contemporary food-based art. 相似文献

This study aimed to analyse how youth basketball players explored numerical overloads during shot attempts by measuring their space occupation across specific court areas. Four process-tracing variables measured how the number of attackers (NA), number of defenders (ND), interpersonal distance between attacker and the closest defender (ID) and distance between attacker and the basket (DBkt) impacted on the performance outcome (converted shot; missed shot; ball possession lost). Ten competitive games involving 13 U14 teams were video recorded and players’ displacements were digitised. The associations between performance outcomes and the process-tracing measures were assessed using standardised mean differences and a cross-correlation function. A multinomial logistic regression was used to calculate the odds ratio (OR) for each of the three possible outcomes. Results revealed that when shot attempts occurred at larger ID and at smaller DBkt, the possibilities to obtain a converted shot increased. The numerical overload of defenders near the scoring target was predominantly associated with offensive success. Also, the possibility of attackers to lead the spatial relation of movements with the defenders, near the scoring target, appeared as a prominent strategy to succeed. In sum, basketball teams that exhibit potential to adapt their collective behaviours to local changes in the environment might be closer to achieving successful outcomes. 相似文献

The present study investigates whether the Early Development Instrument (Offord & Janus, 1999) measures school readiness similarly across different groups of children. We employ ordinal logistic regression to investigate differential item functioning, a method of examining measurement bias. For 40,000 children, our analysis compares groups according to gender, English-as-a-second-language (ESL) status, and Aboriginal status. Our results indicate no systematic measurement differences regarding Aboriginal status and gender, except for 1 item on which boys are more likely than girls to be rated as physically aggressive by Kindergarten teachers. In contrast, ESL children systematically receive lower ratings on items of the language and communication domains—as expected by definition of ESL status—but not within the physical, social, and emotional domains. We discuss how our results fit with child development research and the purpose of the Early Development Instrument, thus supporting its validity. 相似文献

This paper presents some results of an investigation on the number sense of a group of pre-service secondary teachers from Spain. The objective of this research was to analyze students’ use of strategies associated to number sense and compare them with those obtained in a previous study with pre-service primary teachers in Taiwan, (Yang, Reys & Reys, International Journal of Science and Mathematics Education, 7, 383–403, 2009). Pre-service secondary teachers showed lower success than pre-service primary teachers in a number sense test. Nevertheless, these last based their reasoning mainly on rules and algorithms, while pre-service secondary teachers used more strategies of number sense. In an attempt to delve into the low success shown by of Spanish pre-service secondary teachers, some students were interviewed. Those interviews showed that a deeper work on number sense in the training of these students is needed. 相似文献

When Pope Francis, the leader of the Roman Catholic Church, released his encyclical on climate change in June 2015, the Fox News Channel, the most watched cable news network in the United States, faced a dilemma. Some of its news anchors and regular commentators are Catholics, and therefore have a positive bias for the Pope. But the network is also known for its bias against man-made climate change. Guided by cognitive dissonance theory, this study analyzed how Fox News’ anchors and commentators discussed Pope Francis’ stance on climate change. The analysis found a clear ambivalence in their discourse and identified four discursive strategies that they used to navigate discursive dissonance. 相似文献

Owing to the acoustic dimension of music the technical media used in music teaching which serve to store and reproduce sounds, namely tapes and records, are of particular significance. Differences between tape and record in the quality of sound reproduction are few, and are primarily due to the type of tape-recorder and gramophone used. The preparation for sound reproduction must not take too much time and this argument favours the use of the record. But the fact that the musical examples needed for one teaching unit usually have to be collected from a great number of records, which is cumbersome and time-consuming, seems to recommend a combined system as the best solution. The production of efficient teaching aids for music in the form of tapes and records ought to be improved. Commercial firms produce records of musical examples; others produce educational records containing musical examples as well as spoken explanations. There are other records sampling musical quotations for a certain field of study. 相似文献

Are human beings born unequal when it comes to ethics? Or are ethical standards acquired? Or both nature and nurture? Neuroscience is on its way to discovering biological underpinnings of ethics in our brains. Whatever the upcoming findings on this front will be, our philosophical, political, and educational views, and even the way we look at ourselves as a species, could soon be radically challenged, if not altered. AENEIS, the special section of this journal dedicated to Educational Neuroscience and Ethics, seeks to shed light on the crucial and sometimes frightening questions and answers we are to be confronted with. Starting with Charles Lang (“Science, Education, and the Ideology of ‘How”’) and Zachary Stein (“On the Difference Between Designing Children and Raising Them: Ethics and the Use of Educationally Oriented Biotechnology”), we are embarking on a fascinating but dangerous learning journey. To navigate between Scylla and Charybdis, extreme caution is highly recommended. 相似文献

This study considers the experience of school mapping restructure (SMR) in areas of rural China. It aims to understand what happened after SMR implementation. Through a combination of instruments such as questionnaires, interviews and document analysis, the study finds that SMR has impacted positively on the development of education in terms of generating scaling benefits, improved school conditions and educational quality, and more equitable distribution of educational resources. However, there remain several associated problems including longer schooling commute, household financial restrictions and student pressures, and increased teacher work-loads. The study recommends that more structured plans should be developed. Increased stakeholder participation should be enabled, and by providing increased teaching resources to rural schools, implementation should be improved. 相似文献

The organisers of city marathons want to involve a large number of participants and to mobilise the support of local neighbourhoods. This is a particularly difficult challenge in a divided city, especially when the route crosses dividing lines in disputed territories – in which case, organising a marathon carries the risk of generating fresh conflict. But it is possible to avoid such an outcome. Brussels, where the dispute about the city boundaries has always been a peaceful one, has a city marathon that crosses these boundaries, and Belfast, a city with a long history of intercommunal violence, has successfully organised a marathon every year since 1982. Despite the segregation of Beirut's neighbourhoods, the participants in its marathon have run through the whole city since 2003. In Jerusalem, by contrast, a political row over the route of the first marathon in 2011 broke out in the municipal council long before the starter pistol was fired. To examine the reasons for these different outcomes, this article looks at the different types of territorial division in these cities, the types of relationship developed between the marathon organisers and the authorities, and the values the organisers have chosen to promote. 相似文献
