Despite the widespread adoption of Massive Open Online Courses (MOOCs), no business model has emerged to make them sustainable from an institution standpoint. Using MOOCs as a marketing platform shows promise; but for this to succeed, it is necessary to understand the motivations of those who undertake them and to demonstrate how these same motivations can be better satisfied through enrolment in a fee-paying university course. We discuss the motivations for students as they progress through a MOOC and the factors that might lead to subsequent university enrolment. Our arguments are informed by MOOC statistics, the AIDA (attention, interest, desire, action) marketing model, and the literature on adult education, technology adoption, goal seeking and consumer value. We argue that most students are led to MOOC enrolment through close alignment of the course topic and subject matter with their personal goals and through the establishment of an attractive value proposition. Progress in the MOOC depends on whether this goal alignment is maintained, and whether the value assumptions of students are met or exceeded. We predict that subsequent university enrolment will most likely occur when the MOOC experience is both satisfying and representative of the university experience, and where the increased time and financial commitment demanded by formal study is offset by the greater likelihood of attaining the focal goal. For this strategy to succeed, it will be necessary for the host institution to actively work with MOOC students to create an awareness of appropriate fee-paying courses and to promote the benefits of university study. This has implications for the way institutions market their courses to MOOC students. 相似文献

Pro-environmental behaviours associated with reducing, reusing and recycling have become increasingly matters of public policy concern. However, the existing literature on waste management rarely considers the cultural factors associated with predictors and enablers of recycling behaviours, nor has it deeply explored the relation between cultural access and such behaviours. Mindful of the relationship between cultural participation and learning, the main objective of this paper is to examine which Italian regions are ranked among the most ‘efficient’ in recycling, taking into account the variable of cultural participation. Using a Data Envelopment Analysis method applied to Italian regions for the period 2002–2007, we provide a measure of ‘efficiency’ that considers cultural consumptions (as input) and recycling (as output). Public data are drawn from two sources: the Italian Institute of Statistics database, ‘Cultura in cifre’, and the survey ‘Noi Italia – Environment section’. The results from the empirical analysis rank efficient and non-efficient regions in terms of connection between pro-environmental behaviour and cultural participation. The results also indicate a benchmark for ‘inefficient’ regions. The findings add to the discussion of cultural considerations for designing and implementing preventative pro-environmental strategies, that seek to reduce environmental costs and public environmental expenditure by factoring in – rather than out – the importance, role and impact of cultural access and participation. 相似文献

Two different control approaches for suppressing DC-link voltage unbalance in Three-Level Neutral-Point Clamped Converters (NPCs) are presented in this paper. They both guarantee DC-link voltage equalization over any NPC operating conditions, i.e. when the NPC feeds or is supplied by the main AC grid at different active and/or reactive power rates. The proposed control approaches consist of either a hysteresis or a proportional regulator, each of which synthesizes the most suitable control action based on the actual DC-link voltage unbalance. Particularly, two different PWM techniques have been developed in order to achieve DC-link voltage equalization successfully, preserving NPC voltage and current waveforms at the same time. The performances achievable by means of both the proposed control approaches have been compared to each other through an extensive simulation study in order to highlight their most important advantages and drawbacks, as well as their effectiveness over any operating conditions. Particularly, both control approaches are validated in the Matlab-Simulink environment referring to DC-link voltage equalization of an NPC that represents the point of common coupling between a DC microgrid and the main AC grid. 相似文献

In this paper we evaluate the impact of research grants on the amount of collaboration among scientific researchers in Argentina. We find a positive and significant impact of funding on collaboration which is measured in terms of the number of co-authors for publications in peer-reviewed journals. Our identification strategy is based on comparing collaboration indicators for researchers with financially supported projects with those of a control group of researchers who submitted projects that were accepted in terms of quality, but not supported because of shortage of funds. We obtain consistent results by using different non-experimental techniques including difference-in-differences models combined with propensity score matching algorithms. 相似文献

ABSTRACTNoncredit enrollment at community colleges has grown significantly over the past two decades. However, unlike credit bearing programs, noncredit programs are seldomly empirically examined and evaluated, particularly those that are not grant funded. The lack of data results in a gap in knowledge about program effectiveness, as well as the students who participate in noncredit programs, it is difficult to objectively discuss the effectiveness of programs and develop valid policies to support them. This paper specifically aims to: (a) map the relevant literature regarding noncredit program data collection; (b) summarize existing knowledge about data collection processes; and (c) identify existing knowledge gaps in what is known about noncredit data collection. An established five stage process for conducting a scoping review guided the process: (a) identifying the research question; (b) identifying the related body of literature; (c) study selection; (d) presenting of data; and lastly, (e) collating, summarizing, and reporting results. The majority of data collected were head counts, types of courses offered and minimal demographic information. The results also show that, despite higher enrollments and the popularity of programs, there is a lack of comprehensive information on student needs. Thus, it is crucial to develop a standardized data collection system for all noncredit programs; collect data at a student level; and provide more detailed information regarding enrollment, completion, and outcomes such as employment and wage gains, as well as qualitative factors such as student satisfaction. 相似文献

This study examined the relative contribution of age, stage of puberty, anthropometric characteristics, health-related fitness, soccer-specific tests and match-related technical performance to variance in involvements with the ball during recreational 5-a-side small-sided (32 × 15 m) soccer matches. Using a cross-sectional design, 80 healthy male students (14.6 ± 0.5 years of age; range 13.6–15.4) who played soccer recreationally were randomly divided into 10 teams and played against each other. Measurements included height, body mass, pubertal status, health-related fitness (12-min walk/run test, standing long jump, 15-m sprint and sit-ups in 30 s), soccer-specific tests (kicking for speed, passing for accuracy and agility run with and without a ball), match-related technical performance (kicks, passes and dribbles) and involvements with the ball during matches. Forward multiple regression analysis revealed that cardiorespiratory fitness (12-min walk/run test) accounted for 36% of the variance in involvements with the ball. When agility with the ball (zigzag running) and power (standing long jump) were included among the predictors, the total explained variance increased to 62%. In conclusion, recreational adolescent players, regardless of their soccer-specific skills, may increase participation in soccer matches most through physical activities that promote improvement in cardiorespiratory fitness, muscle power and agility. 相似文献

The prevalence of obesity in children has increased dramatically during the past decades in Europe and understanding physical fitness and its components in children is critical to design and implement effective interventions. The objective of the present study was to analyse the association between physical fitness (aerobic, speed, agility, power, flexibility and balance) and body mass index (BMI) in pre-pubertal children. A total of 2411 healthy schoolchildren (7–11 years) participated in this study. Anthropometric characteristics and body composition were assessed by skinfold thickness. Physical fitness was measured by nine physical fitness tests: endurance running, 20 m running speed, agility, handgrip strength, standing long jump and squat jump, sit and reach, medicine ball forward throw and static balance. No relevant differences were observed between boys and girls regarding anthropometric characteristics, body composition and physical fitness. However, overweight and obese children showed significantly lower physical fitness levels in endurance running, speed and agility (mean: +18.8, +5.5 and +14.5% of time to complete tasks, respectively), lower limb power normalised to body mass (?23.3%) and balance tests (number of falls: +165.5%) than their normal weight counterparts. On the other hand, obesity did not affect handgrip, throwing and flexibility. In conclusion, increased BMI was associated with lower performance capabilities limiting proper motor skill development, which directly affects the ability of children to take on sports skills. Actions undertaken to promote children's wellness and fitness should be prioritised and introduced early in life with the aim of enhancing physical fitness as well as preventing overweight and obesity. 相似文献

AbstractThis article explores how social movement co-governance of public education offers an alternative to neoliberal educational models. The Brazilian Landless Workers Movement (MST) is one of the largest social movements in Latin America. We describe one of the many schools that the MST co-governs, the Itinerant School Paths of Knowledge (Caminhos do Saber), located in an occupied encampment in the state of Paraná. We analyze three of the most unique pedagogical innovations in the school: the teacher’s incorporation of ‘portions of reality’ into classroom teaching, the student work collectives, and the participatory student evaluation process. Although these pedagogies are seemingly mundane changes to everyday school practice, we argue that they represent a challenge to the neoliberal educational model being implemented globally. These movement pedagogies are likely to continue, despite recent conservative attacks, and they offer several concrete lessons for how to effectively contest neoliberal educational practices in other global contexts. 相似文献
