Complexity leadership in learning analytics: Drivers,challenges and opportunities

Learning analytics (LA) has demonstrated great potential in improving teaching quality, learning experience and administrative efficiency. However, the adoption of LA in higher education is often beset by challenges in areas such as resources, stakeholder buy-in, ethics and privacy. Addressing these challenges in a complex system requires agile leadership that is responsive to pressures in the environment and capable of managing conflicts. This paper examines LA adoption processes among 21 UK higher education institutions using complexity leadership theory as a framework. The data were collected from 23 interviews with institutional leaders and subsequently analysed using a thematic coding scheme. The results showed a number of prominent challenges associated with LA deployment, which lie in the inherent tensions between innovation and operation. These challenges require a new form of leadership to create and nurture an adaptive space in which innovations are supported and ultimately transformed into the mainstream operation of an institution. This paper argues that a complexity leadership model enables higher education to shift towards more fluid and dynamic approaches for LA adoption, thus ensuring its scalability and sustainability.     

The boundaries of information sharing and integration: A case study of Taiwan e-Government

The paper explores boundaries of cross-boundary information sharing and integration in the context of Taiwan e-Government by using an integrated framework of boundaries adopted from the literature. The discussion of the various boundaries provides a thorough lens to understand the complexity of cross-boundary information sharing and integration. The adopted framework of boundaries is proved to be a useful analytical tool to perceive various vertical and horizontal boundaries in initiatives of cross-boundary information sharing and integration in different e-Government contexts. A new process boundary in the vertical dimension is also identified. In addition, the case shows that centralized information systems can help government agencies to cross the boundaries of information sharing and reduce the number of boundaries government agencies may encounter. Lastly, it is perceived that vertical boundaries are not always easier to cross than horizontal boundaries.     

帕克尔泰夫人的老虎(节选)

萨基是英国小说家赫克托·休·芒罗的笔名。此名取自11世纪波斯诗人欧玛尔·海亚姆所著诗集《鲁拜集》。他的短篇小说多以20世纪初英国上层社会和中产阶级无聊人的生活为题材,讽刺他们的浅薄、庸俗、势利和装腔作势。这群人中大多数游手好闲、穷极无聊,用宴乐、清谈、吹牛、养病、争风吃醋、无事生非来填补生活的空虚。在某些故事里作者也鞭挞了那些只想不劳而获的落魄者。在形式上是传统的,但结构严密、笔调辛辣、对话机智、多警策之言,故事结局往往令人发噱或出人意外。     

Grading Multiple Choice Exams with Low-Cost and Portable Computer-Vision Techniques

Although technology for automatic grading of multiple choice exams has existed for several decades, it is not yet as widely available or affordable as it should be. The main reasons preventing this adoption are the cost and the complexity of the setup procedures. In this paper, Eyegrade, a system for automatic grading of multiple choice exams is presented. While most current solutions are based on expensive scanners, Eyegrade offers a truly low-cost solution requiring only a regular off-the-shelf webcam. Additionally, Eyegrade performs both mark recognition as well as optical character recognition of handwritten student identification numbers, which avoids the use of bubbles in the answer sheet. When compared with similar webcam-based systems, the user interface in Eyegrade has been designed to provide a more efficient and error-free data collection procedure. The tool has been validated with a set of experiments that show the ease of use (both setup and operation), the reduction in grading time, and an increase in the reliability of the results when compared with conventional, more expensive systems.     

Interorganizational collaboration and community building for the preservation of state government digital information: Lessons from NDIIPP state partnership initiative

As a part of the National Digital Information Infrastructure and Preservation Program (NDIIPP), the Library of Congress (LC), partnering with the Center for Technology in Government (CTG), launched an effort in 2005 to integrate state governmental entities into the national network to preserve born-digital information that is both significant and at risk of loss. The main theme that emerged from the efforts of LC, CTG, and the state and federal digital preservation community was the importance of partnership efforts and collaborative strategies for the preservation of state government digital information. Based on the findings of the initiative, this paper discusses challenges and opportunities regarding interorganizational collaboration and community building for digital preservation of state government information. Following the community of practice framework, it is recommended that a “state government digital information preservation community” be developed to facilitate collaboration across agencies and knowledge professionals in state governments.     

Using 9-1-1 call data and the space–time permutation scan statistic for emergency event detection

During medium to large-scale emergency events such as fires or earthquakes, emergency response teams must be deployed to the location of the event in a timely fashion. Information gathered from 9-1-1 call makers is useful for this, but is not always accurate. In this paper, we show how the space–time permutation scan statistic can be used to detect the presence and location of such events by monitoring the overall spatiotemporal pattern of 9-1-1 emergency calls instead. In an analysis of collected 9-1-1 call data, top detected clusters were found to correlate with emergency events as reported on the news, showing the algorithm's usefulness for automatically estimating their location and temporal extent. We show how the detection procedure works in cases where the emergency event generates a small but statistically significant increase in the number of 9-1-1 calls, as well as cases where events must be detected against a large background activity of 9-1-1 calls. We discuss the possible adoption of the proposed algorithm within the next generation digital government framework.     

Preference for color and form in preschoolers as related to color and form differentiation.

The preference for color or form as bases for similarity judgements among preschoolers (ages 2-5) and its relationship to the differentiation of form and color concepts as indexed by discrimination, identification, and labeling were investigated. As hypothesized, an early stage of form preference was found, replicating Brian and Goodenough's results. This was followed by the often-reported color preference and subsequent shift to form preference. A second hypothesis-that the relative salience of a dimension develops in parallel to its relative degree of differentiation-was not supported. This was so despite the fact that, within age groups, individuals who displayed higher proficiency in one dimension that in the other also preferred that dimension over the other. Implications for for existing explanations of developmental trends in preference were discussed.     

Teacher instructional behavior change through self-control

This study illustrates the use of self-control procedures to modify teacher instructional behavior. A teacher wanted to increase the frequency of approval statements and decrease the frequency of disapproval statements. She followed a plan that included self-assessment, self-observation and recording, self-determination of cues, self-determination of performance criteria, self-selection of consequences, and self-administration of consequences. Specifically, the plan included a card self-recording system, cues, and overt rewards. A functional relationship between teacher behavior and student behavior also is suggested by the corresponding reduction in the frequency of inappropriate talk-outs by a target student in relation to the teacher's self-modification.
