ABSTRACTAspects of preventive conservation are central to the long-term preservation of archaeological sites such as Pompeii. Mitigating moisture ingress and its manifold effects on decay mechanisms such as salt degradation are of critical importance when planning durable conservation strategies. A suite of non-destructive techniques was used to diagnose decay mechanisms at an ancient tomb monument at the Porta Nocera Necropolis. Rising damp and salt contamination are shown to be actively contributing to on-going deterioration of the plaster surfaces. An existing shelter is shown to be inadequate in its protection. These initial results are used to inform a more in-depth, long-term survey as well as the design of a holistic preventive strategy. 相似文献

Key points
- The term ‘predatory journal’ hides a wide range of scholarly publishing misconduct.
- The term ‘predatory journal’ unhelpfully bundles misconduct with poor quality.
- The term ‘predatory journal’ blinds us to important possibilities, needs, and questions arising in the developing scholarly landscape.
- The current scholarly publishing environment cannot rely on such a simplified classification of journals into predatory or not.

The present study examined the comorbidity between attention-deficit/hyperactivity disorder (ADHD) and reading disability (RD) in male adults. Participants were 120 men, of whom 24 were classified as having ADHD. The basis for the diagnosis was two self-report scales validated by interviews and background data. An extensive battery was used to assess phonological abilities and various aspects of reading skills. No differences were obtained between adults with and without ADHD on measures of either phonological processing skills or word decoding, indicating a low comorbidity with RD. This finding was valid even when different criteria were used to diagnose RD. However, the two groups differed in reading comprehension, with individuals with ADHD performing poorly in tests of reading comprehension. These results are compatible with the view that reading comprehension involves many of the higher cognitive control functions assumed to be impaired in ADHD. However, these attentional control functions are not critical to word recognition, which is determined by a more encapsulated phonological processing module. The pattern of associations between ADHD and RD observed in the present study is explained with reference to the differential attentional demands of the two aspects of reading. 相似文献

The assumption that today’s German students are able to successfully combine synthesis achievement values and well-being values
appears to be overly optimistic when regarded from the perspective of motivational psychology. The results of a qualitative-quantitative
interview study with 25 students indicate that achievement and well-being values may come into conflict in everyday life.
Incentives for achievement and well-being rarely co-occur in the same action domains. Whereas the school context is dominated
by achievement incentives, leisure time is dominated by well-being incentives. Since both achievement and well-being are appreciated
by most students, they should be prone to experience frequent everyday action conflicts. The motivational characteristics
of postdecisional action conflicts are described on the phenomenal level and their possible impairing effects for learning
processes are pointed out. Finally, alternative forms of value synthesis, which might be realized more successfully, are discussed. 相似文献

In search of determinants of decision- making, cognitive aspects for years have been predominating in scientific discussions for years, whereas recently emotional aspects have increasingly became the focus of scientific consideration. In view of the frequently occurring, and not only philosophically relevant, discussion about the free will and the architecture of our spirit, the question arises whether these approaches reach far enough. In the decision-making process different, more deeply lying and unconsciously working structures appear to be decisive, whose modes of function we can neither comprehend introspectively nor can be easily approached on a scientific basis. As a consequence, to knowledge of these parameters is of great importance for any discussion about possible influences on determinants of decision -making, which on the other hand are generally considered to be the fundamental principles in the promotion of healthy sports. 相似文献

There currently exists a dearth of research on the transmission and assimilation of myths. To overcome this limitation, we developed a novel scale that measures belief in science-related myths. A total of 363 participants completed this new scale along with measures of personality (the Big Five factors), anti-scientific attitudes, and New Age orientation. Exploratory factor analysis showed that the items of the belief in myths scale could be reduced to two factors concerning human-related and non-human-related myths. Both factors were internally reliable, were moderately inter-correlated, and were not rated significantly differently by women and men (although human-related myths were rated as significantly more believable than non-human-related myths). Further analysis showed that only human myths were significantly predicted by anti-scientific attitudes and the Big Five factor of Extraversion. These results are discussed in relation to the promotion of scientific literacy. 相似文献

Social media hype has created a lot of speculation among educators on how these media can be used to support learning, but
there have been rather few studies so far. Our explorative interview study contributes by critically exploring how campus
students perceive using social media to support their studies and the perceived benefits and limitations compared with other
means. Although the vast majority of the respondents use social media frequently, a “digital dissonance” can be noted, because
few of them feel that they use such media to support their studies. The interviewees mainly put forth e-mail and instant messaging,
which are used among students to ask questions, coordinate group work and share files. Some of them mention using Wikipedia
and YouTube for retrieving content and Facebook to initiate contact with course peers. Students regard social media as one
of three key means of the educational experience, alongside face-to-face meetings and using the learning management systems,
and are mainly used for brief questions and answers, and to coordinate group work. In conclusion, we argue that teaching strategy
plays a key role in supporting students in moving from using social media to support coordination and information retrieval
to also using such media for collaborative learning, when appropriate. 相似文献

The aim of the present study was to design, construct and scientifically validate a two-dimensional force measurement binding system for cross-country skiing. The system consists of two force measurement bindings. One binding was designed for analysing classic skiing (vertical and anterior–posterior [along the ski] force components) and the other one for skate (freestyle) skiing (vertical and medio-lateral [transverse to the ski] force components). Validation was accomplished using a three-step process: (1) accuracy tests for the sensors in two temperatures, (2) sport-specific imitation jump test on standard force plates in a laboratory and (3) comparing the system against force measurement reference systems that are currently used when skiing on snow. During sport-specific imitation jumps, differences in peak forces and impulses between the classic binding and the reference systems ranged from 8.0 to 19.9 % and were two to three times greater compared to differences between the skate binding and the reference systems (range ?5.9 to 5.5 %). However, high similarity coefficients were observed with both bindings (classic binding 0.990–0.996, skate binding 0.996–0.999) compared to the reference systems. Based on these results, the skate binding was shown to be fully valid for use in field measurements of skate skiing, whereas some improvements have to be performed in the construction and sensor placements for the classic binding (vertical as well as anterior–posterior force component). 相似文献

This paper deals with the topic of professional development programmes’ impact. Concepts and ideas of action research, constructivism, and systems theory are used as a theoretical framework and are combined to describe and analyse an exemplary professional development programme in Austria. Empirical findings from both quantitative and qualitative studies regarding the programme’s impact are provided and discussed. Moreover, implications for future programmes’ planning and implementation are provided. 相似文献
