The world economy, already launched toward the globalization of markets, is strenuously searching for nonrenewable natural resources, to exploit in the productive processes to satisfy the demands of a world population in continuous growth. In such a context ecological taxation can contribute to the resolution of environmental problems, stimulating the entrepreneurs to appraise opportunities, not only environmental but also economical, that spring from the introduction of innovations of sustainable processes. With this in mind this article has proceeded with an evolutionary adaptation of the environmental curve of Kuznets, through a three-dimensional re-elaboration inserting as a third variable the sustainable technological component and showing how this can represent a valid tool of environmental politics for the attainment of an acceptable level of pollution for society in developed countries. Therefore, the objective of public governance is to favor research in the field of sustainable technology and to induce, even through the introduction of environmental taxation and facilitations, enterprises to use productive eco-compatible processes with the purpose of improving the general level of the quality of life in harmony with the concept of sustainable development.  相似文献

ABSTRACT

Effective parent training programs may need to be tailored for at-risk parents by using simple language, presenting concrete concepts, and simple technologies. We present four single-case research-design studies examining if the use of digital frames enhances parent-infant interactions with a diverse range of mothers with varied levels of risk for maltreatment. Based on self-modeling, the frames contain photographs of mother-infant dyads in posed interactions representing desired criterion behaviors from the parent-infant interaction (PII) module of SafeCare®. Results indicate that the use of inexpensive digital frames appears to enhance already good outcomes of the SafeCare PII module.  相似文献

Existing research on the characteristics of digital natives, traditionally defined as those born after 1980, has shown subtle differences in how they approach technology compared with other cohorts. However, much of the existing research has focused on a limited set of conventional technologies, mostly related to learning. In addition, prior research has shown differences within this cohort in how they respond to autonomous technology (e.g., trust, reliance; Pak, Rovira, McLaughlin, &; Baldwin, 2016 Pak, R., Rovira, E., McLaughlin, A., &; Baldwin, N. (2016). Does the domain of technology impact user trust? Investigating trust in automation across different consumer-oriented domains in young adults, military, and older adults. Theoretical Issues in Ergonomics Science, 18, 199220. 10.1080/1463922x.2016.1175523[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). The purpose of this short report, representing the first wave of data collection in a larger study examining technology experience and attitude change, is to directly address 2 shortcomings in the literature on digital natives which tends to emphasize: (a) civilian students; and (b) conventional, often learning technologies. We addressed these 2 issues by recruiting 2 subgroups of digital natives (students and military cadets) and assessing attitudes and experience with a wide range of technology spanning from conventional (e.g., mobile) to emerging (e.g., robotics). The results showed that that both groups were surprisingly unfamiliar with emerging consumer technologies. Additionally, contrary to expectations, cadets were significantly, albeit only slightly, less experienced with mobile technologies, VR/augmented reality, social media, and entertainment technology as compared to civilian undergraduates.  相似文献

ObjectiveThe objective of the present study is to build upon the existing literature examining the coaching context and how it relates to coaches' use of autonomy-supportive interpersonal behaviours (i.e. Stebbings, Taylor, Spray, & Ntoumanis, 2012) by identifying additional environmental factors and exploring the role of coach motivation.DesignAn academic model designed by Pelletier, Seguin-Levesque, and Legault (2002) to predict teacher motivation and autonomy-supportive styles in academic settings, was adapted to the coaching context.MethodsThe influence of pressure from above (sport administrations) and pressure from below (athlete motivation) on coach motivation and autonomy-supportive coaching behaviours was tested using structural equation modeling.ResultsResults support the fit of the model in a sport context.ConclusionsPressure from above, pressure from below, and coach motivation predict coaches’ reported use of autonomy-supportive behaviours.  相似文献

ObjectivesThe present study is a review on studies about the relationships between the three basic psychological needs/motivational regulations (i.e., amotivation, controlled regulation, extrinsic autonomous regulation, and intrinsic motivation) and burnout.DesignA systematic review and meta-analysis.MethodStudies were identified through five electronic databases and manual search using combinations of three groups of keywords. Three inclusion criteria were then used to screen the searched articles.ResultsEighteen studies met the inclusion criteria and these studies varied considerably in terms of their study characteristics (e.g., characteristics of participants, study designs, and outcome measures). The results also showed that the three basic psychological needs, intrinsic motivation, extrinsic autonomous regulation, and amotivation had small to large effects on predicting global burnout and its three dimensions. However, controlled regulation showed no or weak correlations with the burnout subscales.ConclusionsSelf-determination theory was generally supported in explaining athlete burnout.  相似文献

This paper investigates the groundwork upon which the concepts of mediatisation and mediation were erected, focusing on the very definition of what media-technology is. These concepts frame the conversation among scholars in the study of religion and media. However, despite the fact that the two keywords share the same root, media, they are understood as incompatible with one another. On the one hand, mediatisation is broadly defined as a historical shift in which the logic of mass media transforms traditional forms of religion, subsuming them under the imperative of the modern marketplace. On the other hand, scholars studying the mediation of religion affirm that media have always shaped and transformed religious practices. This investigation argues that the controversy between the two modes of analysis does not consist of whether or to what extent media technology affects or transforms religion. Rather, the conflict arises from how media technology is defined.  相似文献

The practice of daily prayers in Islam and how observances such as Ramadan fall each year follow specific solar or lunar calendars different from the Gregorian calendar of UK work places. Identifying the time for daily prayers and finding a place to practise is a skilled activity requiring ways to ascertain the correct (and changing) time and a place in which prayer can take place. In the absence of traditional mediation such as the call to prayer broadcast from a local mosque, new, often technologically innovative, approaches are being adopted. This paper reports on a study of how Muslims practise and negotiate the difficulties of performing daily prayers in a UK university. Though technological mediation is a significant aspect of daily prayers, it is but one part of a complex practice which often involves multiple technologies and multiple ways of working.  相似文献

Fifty-three national level cyclists completed competitive rides under both laboratory and field conditions to investigate the relationship between pre-competition anxiety and performance. A total of 39 males and 14 females participated in the study, ranging in age from 19 to 26. The objectives of the study were to, (a) measure the relationship between state anxiety and performance, (b) investigate differences in the anxiety-performance relationship under laboratory versus field conditions, and (c) examine the effect of trait anxiety on the state anxiety-performance relationship. State anxiety was measured using the Competitive State Anxiety Inventory-2 (CSAI-2; Martens, Vealey, & Burton, 1990), and trait anxiety with the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, & Lushene, 1970). Results indicated that anxiety was strongly correlated with performance on the field test, but that the anxiety-performance relationship was weaker under laboratory conditions. Results also showed that trait anxiety interacted with the relationship, as low and high trait-anxious subjects had differential response patterns to pre-competition anxiety. The findings are discussed in terms of their relevance for both practitioners and researchers.  相似文献

Abstract

In a reply to our paper (Kohlmann, Schumacher, & Streit, 1988), Rosenthal (in a Letter to the Editors, this issue) primarily gives some comments on findings regarding the association of inconsistent child-rearing behavior and anxiety in the child. Results of our study were compared to results from a study by Rosenthal, Finkelstein, Ni, and Robertson (1959).  相似文献

Abstract

This paper investigates athletes' perception of the relationship between cognitive interference and its effects on concentration and effort during sport performance. The sample consisted of 115 volleyball players that took part in a national university tournament. Three different kinds of thoughts were investigated: ‘performance worries’, ‘situation-irrelevant thoughts’, and ‘thoughts of escape’. Path analysis was used to examine the relationships. All kinds of thoughts were reported to be detrimental to concentration, whereas different patterns of associations emerged between different thoughts and subsequent effort. ‘Performance worries’ were reported to be related to increases in effort for athletes holding higher goal attainment expectancies and decreases in effort for athletes holding lower goal attainment expectancies. ‘Thoughts of escape’ were reported to be related to decreases in effort, while no significant relation between ‘situation irrelevant thoughts’ and effort emerged. Results stress the importance of further examining the role of interfering thoughts athletes experience during competition.  相似文献
