The aim of this study was to explore how time frames affect pupils and teachers in cooking activities during lessons of different durations for Home and Consumer Studies, with a specific focus on the pupils’ experiences. To investigate this, classroom observations were carried out in 2011 and 2012, with the help of audio and video recordings in three different schools in Sweden and included altogether 22 pupils (18 girls, 4 boys) in grade 9 (15–16 years). Each class was observed during two separate lessons, lasting between 1 h 50 min (110 minutes) and 2 h 20 min (140 min). The six lessons resulted in 12 h of video recorded time and 80 h of sound recordings. The study showed that the importance of finishing on time seemed to be ingrained in most pupils in all classes and the end result was perceived as more important than the process of cooking. The study also showed that knowledge of cooking skills and time management seemed important for success in grade‐related tasks. Pupils demonstrated different ways of handling the time frames, e.g. using various methods to speed up the cooking process. This study raises important questions about the relationship between national and local time frames and the curriculum aims in Home and Consumer Studies.  相似文献

This empirical investigation showed that contrary to the popular notion that apologies signify weakness, the victims of mistakes made by leaders consistently perceived leaders who apologized as more transformational than those who did not apologize. In a field experiment (Study 1), male referees who were perceived as having apologized for mistakes made officiating hockey games were rated by male coaches (n = 93) as more transformational than when no apology was made. Studies 2 (n = 50) and 3 (n = 224) replicated this effect in two vignette studies to enhance internal and ecological validity. Contrary to expectations in Study 3, there were no apology×leader gender interactions. Theoretical and practical implications are discussed.  相似文献

The main forest transitions that took place in south-central Chile from the end of the last glaciation to the present are reviewed here with the aim of identifying the main climatic and socio-economic drivers of land cover change. The first great transition, driven primarily by global warming, is the postglacial expansion of forests, with human populations from about 15,000 cal. yr. BP, restricted to coastlines and river basins and localized impact of forest fire. Charcoal evidence of fire increased in south-central Chile and in global records from about 12,000 to 6000 cal. yr. BP, which could be attributed at least partly to people. The subsequent expansion of agriculture led to much clearing of forests and the spread of weeds and other indicators of open habitats. The Spanish colonial period in America may have been followed by a transient expansion of forest cover into abandoned land, as indigenous population declined rapidly due to disease and slaughter. The 18th and 19th centuries brought about extensive loss of forests due to the massive impact of lumber extraction for mining operations both in central Chile and in western North America. Two centuries of intensive deforestation, coupled to grazing by cattle and extremely variable rainfall had long-lasting effects on forest cover in south-central Chile, which persist until today. The transition from a preindustrial to an industrial society brought about the “golden age” of timber harvest, assisted by mobile sawmills and railway transportation since the late 1800s. These advances led to the exhaustion of native commercial timber by the late 20th century in south-central Chile. In North America, harvestable stands were exhausted in New England and the Midwest around 1920. Settlement of the independent territories in the late 1800s and early 1900s implied vast burning and clearing of land and mounting soil erosion. Industrial forestry, based on government-subsidized massive plantations of short-rotation exotic trees, developed in the late 20th century, in connection with postindustrial displacement of exploitative activities from developed to third-world nations. In the last two decades, economic globalization and free trade promoted the expansion of new crops and further decline of woodlands, despite modest increases in forest cover. These patterns are repeated in many Latin American countries. To prevent further depletion of native forest resources and to provide an insurance against climate change, in the 21st century developing nations should aim at: (1) relocating subsidies from fiber farms to restoring diverse forest cover, (2) promoting ecosystem management of diverse forest and crops within landscapes, and (3) fostering diverse cultural relationships between people and their land.  相似文献

The paper explores the complex relationship between technical and service characteristics discussed by the Saviotti–Metcalfe model of innovation. It is proposed that principal components analysis (PCA) is a more appropriate method of analysing this relationship than approaches previously used. A PCA is performed on a dataset of mobile phone handsets for the period 2003 to 2008. In addition to the relationship between technical and service characteristics, the analysis explores the existence of clusters of ergonomic characteristics within mobile phone handsets. The findings indicate that a limited set of core technology components underpin the large set of service characteristics offered by mobile phone handsets, and that the mapping between technical and service characteristics can be highly complex.

The authors discuss the consistency of transnational companies in their home, as well as in less developed host countries, concerning ethics, values and social responsibility. Ethical behavior offers good reputation, credibility and tradition to the corporation. It leads to corporate social, environmental and economic responsibilities, cooperating to the desired sustainability. This paper analyzes the inversion of values that corporate governance systems have suffered. The meaning and implication of the corporate social responsibility is investigated and discussed. A “pyramid of values” is built upon individual ethical values at the basis. Over them, the organizational ethical values should indicate the limits of operations, so that the corporate social responsibility can be sustained, in the top. The authors comment that ethical values no longer lead the organization. Its communication with the stakeholders, specifically through reports, has been gradually replacing the code of ethics and corporate values. These reports have taken the basis of the pyramid leading the organizations to socially irresponsible and unethical behavior. They do not guarantee transparency or communicate the needs of the society. It appears that transnational companies do not behave the same way in their home country as they do in host countries, particularly in less developed regions like Latin America and Africa. Lack of communication and transparency may induce employees to unethical decisions and transform the reporting system into a marketing instrument. In order to guarantee compliance with the codes, transparency and ethical responsibility, communication within the organization is essential.  相似文献

Pests create biodiversity effects that increase food production risks and decrease productivity when agricultural production is specialized. Pesticides contain these effects, but damage the environment and human health. When opening to trade, governments are tempted to restrict pesticide use because, with more food being imported, less pesticide is needed for domestic consumption. However, pesticide restrictions hinder the competitiveness of their agricultural sector on international markets. We show that restrictions on pesticides are more stringent under free trade than under autarky, which reduces the gains from trade, and that trade increases food price volatility.  相似文献

Turnover intention is widely regarded as a direct antecedent to and proxy for actual voluntary turnover behaviour. However, previous studies have found the turnover intention-behaviour link to be highly heterogeneous and not necessarily strong. This study adopts a cross-cultural perspective, examining how the link varies as a function of Hofstede’s four work-related cultural dimensions. Data from 152 independent samples were meta-analysed, representing the testing of 216,093 employees from 18 nations across 9 geographical regions. The multilevel meta-analytic results reveal significantly stronger turnover intention-behaviour links for countries higher in power distance, higher in individualism, and lower in masculinity.  相似文献

The aim of this study was to investigate consumer preference for the novel red-fleshed apple genotypes. The information presented provides us with insight into consumer propensity to accept a new variety with radical visible innovative attributes and societal demand for a more sustainable production. The survey was carried out on the population of a province in central Italy, where there is consumer demand for organic and high-quality foods. The consumers’ opinions contrasted greatly and can be divided into two groups. Over one quarter of the respondents declared that they did not like the innovative fruit. The cluster analysis and CHAID analyses were performed on the consumers’ responses to determine sample groupings. Three clusters were identified among the consumers with positive opinions, enthusiastic, health-conscious, and unmotivated illustrating how the hierarchical level of preferences of the potential consumers of the red-fleshed apple fruit are triggered by various motivations. The surveys also pointed out that most consumers of the sampled population were not biased against research activities producing innovative food products. A large number of consumers, especially women, declared that they were willing to pay a higher price considering the increased nutritional value of red-fleshed apple fruits. By examining the broad context of this study, decision-making researchers and operators of the fruit industry will be able to make informed and realistic predictions concerning possible future scenarios and to determine the possible effects and desirability.  相似文献
