As a new social media platform, short-form video apps integrate the dual functions of e-commerce and social networking. The proliferation and high penetration rate of this kind of app have resulted in online user concerns about the privacy security problems exposed by such platforms. This study focuses on better understanding the impact mechanism of private information disclosure behaviors and obtained benefits on privacy concerns of short-form video platform users. We analyzed the behavioral and privacy setting data of 35,456 users registered on the TikTok platform. The results demonstrated a correlation between use behaviors (e.g., participation and interest) and privacy sensitivity, among which popularity, as a form of external feedback, played a mediating role. In addition, the official certification provided to users by the platform moderated the impact of user popularity on privacy sensitivity. This study enriches the understanding of the correlation between privacy concerns and information disclosure behavior and suggests practical implications for the design of privacy settings and protections by short-form video platforms. 相似文献

After independence, Zimbabwe adopted two major land reform programmes to address the racially skewed land ownership. Due to the perceived failure of these programmes, the country embarked on a highly politicised and forceful acquisition and re-distribution of white owned commercial farms under the Fast Track Land Reform Programme (FTLRP). Whereas a large number of Zimbabweans have been allocated land under the programme, there has been a significant decline in agricultural productivity and an increase in degradation of land and associated resources. Popular opinion has even suggested the country’s current socio-economic challenges are linked to the programme. Mitigating land degradation, enhancing agricultural productivity and promoting natural resources sustainability requires an objective understanding and determination landscape transformation within relevant administrative decision making spatial extents. In this study, we adopted multi-temporal remotely sensed imagery to determine landscape transformation after the implementation of the FTLRP in Chipinge administrative district, characterised by heterogeneous land usage and natural resources. Major land-use-land-cover types were determined using the Support Vector Machine classification algorithm and accuracy established using field survey and ancillary data. Results show significant landscape transformation after the implementation of the FTLRP. Specifically, there was a decline in plantations, small farms, water bodies and forests and an increase in bare areas and settlements. This study demonstrates the value of remotely data in monitoring landscape transformation arising from a shift in policy. Furthermore, these results provide an insight into multi-temporal spatial changes in cultivated, natural and degraded lands, valuable for designing measures to improve landscape productivity and to adopt relevant rehabilitation measures. Understanding multi-temporal landscape change within an administrative boundary is particularly valuable for area specific planning, policy formulation and adoption of desired mitigation measures. 相似文献

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

随着经济金融的健康、快速发展,以及支付技术日新月异的变化,我国城镇支付服务水平不断提高。但在广大的农村地区尤其是偏远农村地区,其支付服务环境相对落后,亟待改善。2011年7月开始,各银行业金融机构开展了全面推广银行卡助农取款服务工作,以满足偏远农村地区各项支农补贴资金、日常小额取现、余额查询等基本金融需求。本文通过调查某偏远县推广银行卡助农取款服务工作情况,指出了偏远农村地区推广助农取款服务存在的问题,并针对存在的问题给出了相关政策建议。 相似文献
