Explanations of attitudes to change: Colombian mathematics teachers’ conceptions of the crucial determinants of their teaching practices of beginning algebra

This article arises from a study whose overall purpose was to investigate the relationship between Colombian mathematics teachers’ conceptions of beginning algebra and their conceptions of their own teaching practices. The teachers’ understandings of their teaching practices were explored with a view to unravelling their conceptions of change in their teaching. Focusing on the perspectives of teachers afforded opportunities that exposed the powerful role that the teachers’ conceptions of social/institutional factors of teaching played in their conceptions of their practices. The degree to which the teachers attributed these (external) factors as crucial reasons for what they do in their teaching was the basis of a categorisation of their conceptions of the crucial determinants of their teaching practices into three types. The findings are particularly relevant to our understanding of the stability of mathematics teaching approaches in the Colombian context but have likely implications for a range of international education contexts. Specific implications for the development of the research into teachers’ conceptions of mathematics and its teaching, and for teacher education programmes are presented.

试论“现代文化”的理论与实践

文章认为,现代文化是指人们适应现代化本质要求的文化,就是实现文化的现代转型并建设现代价值、形成现代认同、张扬现代精神并进而建设共同信仰的文化。现代文化的主要内核与社会主义核心价值体系和社会主义价值观体系存在着一致性和耦合性。现代社会的现代价值、现代认同、现代精神和文化的现代转型是现代文化及其建设的核心内容和主要任务。现代价值是现代文化的基础,现代认同是现代文化的支撑,现代精神是现代文化的动力,文化现代转型是现代文化建设的途径,建设现代文化的目标就是建设信仰共同体。现代文化的这四个要素相互依存,相互补充,相互作用,紧密联系,现代文化是先进文化发展过程中的一个环节。文章还提出了新疆"疆魂"的概念以及实现文化现代转型的途径。

Parents’ PTSD symptoms and child abuse potential during the perinatal period: Direct associations and mediation via relationship conflict

BackgroundPosttraumatic stress disorder (PTSD) symptoms are associated with parental aggression towards children, but little is known about the relation between parents’ PTSD symptoms and their risk for perpetrating child physical abuse during the early parenting years, when the potential for prevention of abuse may be highest.ObjectiveTo examine direct associations between mothers’ and fathers’ PTSD symptoms and child abuse potential, as well as indirect effects through couple relationship adjustment (i.e., conflict and love) in a high-risk sample of parents during the perinatal period, most of whom were first-time parents.Participants and settingFrom March 2013 to August 2016, data were collected from 150 expecting or new parental dyads in which the mother was participating in a home visiting program.MethodsData were analyzed using the Actor-Partner Interdependence Mediation Model.ResultsFor mothers and fathers, there were direct associations between PTSD symptom severity and child abuse potential (βs = .51, ps <.001), and this association for fathers was stronger at higher levels of mothers’ PTSD symptoms (β = .15, p = .03). In addition, parents’ own and their partners’ PTSD symptoms were each indirectly associated with parents’ own child abuse potential through parents’ report of interparental conflict (standardized indirect effects = .052–.069, ps = .004) but not love.ConclusionsAddressing parents’ PTSD symptoms and relationship conflict during the perinatal period using both systemic and developmental perspectives may uniquely serve to decrease the risk of child physical abuse and its myriad adverse consequences.     

Demystifying blockchain: A critical analysis of challenges,applications and opportunities

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.     

衡水湖国家级自然保护区湿地景观格局演变分析

基于1987年、1997年和2005年3期TM遥感数据,对衡水湖的湿地景观空间格局及其演变进行分析,结果表明：该区域以农田为景观基质,水体和芦苇沼泽交错分布构成区域湿地生境的主体斑块,其余景观类型呈以小尺度斑块散布于区域中。保护区湿地景观改变较明显,湿地由1987年的20.2%上升到1997年的23.4%,2005年占到22.3%,农田向湿地类型的转变最为显著,农田和湿地类型之间的动态转换关系很大程度上决定了保护区土地利用结构和景观格局的演变。从景观类型水平来看,表现为水体的平均斑块面积增加,由1987年的3.5187hm²减到1997年的2.0187hm²到2005年为4.3997hm²,破碎度指数下降;聚合度指数和最大斑块指数先降后升,而连接度指数先增后减;芦苇沼泽平均斑块面积下降明显,由1987年的2.6169hm²降到1997年的0.5437hm²,到2005年为0.3558hm²,且形状日趋复杂自然,最大斑块指数和聚合度指数持续减少,而连接度指数的变化趋势则相反,但总体上芦苇沼泽沼泽小面积斑块数量仍占相当比例,破碎化程度仍维持较高水平。在景观整体水平上,保护区的景观多样性和均匀度指数呈缓慢上升趋势,破碎化指数由1987年的51.068增到1997年的74.0985后2005年减为37.88,以农田为景观基质的蔓延度指数则先降后升。景观格局分析表明,衡水湖保护区湿地面积逐步恢复,破碎化程度降低且景观日趋多样化,连通性虽不及1987年历史最高水平却呈加强趋势,湿地生境质量得到优化,2005年湿地恢复的景观格局的空间配置达到3个时期的历史最高水平,也体现了保护区规划管理取得一定成效。

Guideposts and Roadblocks to the Career-Long Scholarly Engagement of Physical Education Teacher Education Faculty

Purpose: Scholarship is essential for the growth and development of the physical education field. Over time, scholarship expectations have changed, forcing faculty members to alter time spent for research, teaching, and service. Social-cognitive career theory (SCCT) presents a model for understanding performance and persistence in an occupational environment. The interconnected aspects of SCCT have different emphasis related to self-efficacy, outcome expectations, or personal goals pursuit. This study explored physical education teacher education (PETE) faculty members’ continuing engagement in scholarly activity through SCCT. Method: Data collection included interviews with 9 senior PETE faculty members who met the criteria for “productive scholars over time.” Curriculum vitae were collected to verify productivity. Results: Data analysis revealed guidepost themes that included collaborating, finding balance, defining a research process, and maintaining a strong work ethic. Roadblocks encountered included other obligations and lack of support for research. Conclusions: Participants demonstrated strong self-efficacy; held high, positive expectations for success; and set very specific, clear, and deliberate goals. Participant behavior was moderated by their personal attributes (capacity to build relationships, set goals, and maintain interest and passion) and was tempered by the environments in which they worked. Fostering similar behaviors has the potential to guide future and current PETE faculty members in creating supportive and encouraging atmospheres for sustained productivity. The lack of literature relating to this topic warrants the need for more research exploring the influential factors and benefits gained from sustained scholarly productivity over time for PETE faculty members.
