This article describes AppMonitor, a Microsoft Windows-based client-side logging tool that records user actions in unmodified Windows applications. AppMonitor allows researchers to gain insights into many facets of interface interaction such as command use frequency, behavioral patterns prior to or following command use, and methods of navigating through systems and data sets. AppMonitor uses the Windows SDK libraries to monitor both low-level interactions, such as "left mouse button pressed" and "Ctrl-F pressed," as well as high-level "logical" actions, such as menu selections and scrollbar manipulations. The events recorded are configurable, allowing researchers to perform broad or targeted studies. No user input is required to manage logging, allowing participants to seamlessly conduct everyday work while their actions are monitored. The system currently supports logging in Microsoft Word and Adobe Reader; however, it could be extended for use with any Microsoft Windows-based application. To support other researchers wishing to create multilevel event loggers, we describe AppMonitor's underlying architecture and implementation, and provide a brief example of the data generated during our 4-month trial with six users.  相似文献

University based academic Research Ethics Boards (REB) face the particularly difficult challenge of trying to achieve representation from a variety of disciplines, methodologies and research interests. Additionally, many are currently facing another decision – whether to have students as REB members or not. At Ryerson University, we are uniquely situated. Without a medical school in which an awareness of the research ethics review process might be grounded, our mainly social science and humanities REB must also educate and foster awareness of the ethics review process throughout the academic community. Our Board has had and continues to have students as active members. While there are challenges to having students as Board members, these are clearly outweighed by the advantages, for both the academic community and the future of ethically sound research in the social sciences and humanities. Moreover, the challenges are often based on misconceptions and can be easily overcome through increased education and understanding of the research ethics review process by the academic community at large. The purpose of this paper is to describe and discuss the experiences, advantages and challenges of having students as REB members. The advantages of having students as REB members include the following: (1) Students are the proposed participants in many of our reviewed protocols and student members may illuminate unique issues of participation. (2) Students are active and highly engaged members of the REB. (3) Having students on the REB enhances awareness of research ethics within the University. (4) Student REB members have an opportunity to mentor other students and provide leadership for both undergraduate and graduate students. (5) Students are more vigorously recruited than faculty members and often apply for student positions with enthusiasm and preparation. (6) In creating an atmosphere of excellence in research, engaging students at the beginning of their research career will help in creating tomorrow’s leaders in research and research ethics. The challenges of having students as REB members include the following: (1) Faculty members may be uneasy regarding the prospect of students reviewing protocols. (2) Faculty members may be concerned about confidentiality and respect with students reviewing faculty research protocols. (3) There may be an increased burden for students who serve as members on an REB. (4) There is concern that students will offer less continuous service to the REB. (5) There is a common misconception that students do not have the experience to carry out ethical reviews. While there are challenges from faculty members and others regarding having students as REB members, these challenges are often based on misconceptions about the nature of the REB work and the ethics review process in general. These challenges are also often based on the misconception of the ethics review process as one of peer review and evaluation, instead of a community-based and inclusive process. Having student members is a long-term strategy for both overcoming the misconceptions of the REB as a “necessary evil” and for fostering an awareness of the imperative for ethically sound research in the social sciences and humanities.  相似文献

Theories of objects recognition, scene perception, and neural representation of scenes imply that jumbling a coherent scene should reduce change detection. However, evidence from the change detection literature questions whether jumbling affects change detection. The experiments reported here demonstrate that jumbling does, in fact, reduce change detection. In Experiments 1 and 2, change detection was better for normal scenes than for jumbled scenes. In Experiment 3, inversion failed to interfere with change detection, demonstrating that the disruption of surface and object continuity inherent to jumbling is responsible for reduced change detection. These findings provide a crucial commonality between change detection research and theories of scene perception and neural representation. We also discuss why previous research may have failed to find effects of jumbling.  相似文献

The relationship between learning environment characteristics and academic engagement of 777 Grade 6 children located in 41 learning environments was explored. Questionnaires were used to tap learning environment perceptions of children, their academic engagement, and their ethnic-cultural background. The basis of the learning environment questionnaire was the International System for Teacher Observation and Feedback (ISTOF). Factor analysis indicated three factors: the teacher as a helpful and good instructor (having good instructional skills, clear instruction), the teacher as promoter of active learning and differentiation, and the teacher as manager and organizer of classroom activities. Multilevel analysis indicated that about 12% of the differences in engagement between children was related to the learning environment. All the mentioned learning environment characteristics mattered, but the teacher as a helpful, good instructor was most important followed by the teacher as promoter of active learning and differentiation.  相似文献

From the evidence reported in the recent guidelines [Heinrichs et al. (2009) Evidenzbasierte Leitlinie zur Psychotherapie der Panikst?rung mit und ohne Agoraphobie. Hogrefe, G?ttingen] the following conclusions can be drawn with respect to the treatment of panic disorder with or without agoraphobia, as well as for agoraphobia without panic disorder:
  1. Every psychotherapy should be preceded by suitable diagnostics and a case formulation.
  2. The effectiveness of every psychotherapy should be evaluated with well established measures.
  3. For the treatment of panic disorder without agoraphobia, cognitive behavioral treatment (CBT) and applied relaxation have been shown to be effective (evidence grade 1).
  4. For panic disorder with agoraphobia, CBT, combination treatment (CBT plus medication), as well as panic-focused psychodynamic psychotherapy in the outpatient setting have shown short-term effectiveness (evidence grade 1). Longer lasting effects have been documented for CBT (evidence grade 1).
  5. For agoraphobia without panic disorder, CBT with a focus on situational exposure can be recommended (evidence grade 1).

This study examined the relationship between cognitive ability, personality, and academic achievement in post-secondary students, using latent variable models. Testing both simple and complex relationships, we found that cognitive ability and personality predicted reading achievement independently, but that they interact when predicting math achievement - at least in the Conscientiousness and Openness to Experience domains.  相似文献

Although anti-terrorism policy should be based on a normative treatment of risk that incorporates likelihoods of attack, policy makers’ anti-terror decisions may be influenced by the blame they expect from failing to prevent attacks. We show that people’s anti-terror budget priorities before a perceived attack and blame judgments after a perceived attack are associated with the attack’s severity and how upsetting it is but largely independent of its likelihood. We also show that anti-terror budget priorities are influenced by directly highlighting the likelihood of the attack, but because of outcome biases, highlighting the attack’s prior likelihood has no influence on judgments of blame, severity, or emotion after an attack is perceived to have occurred. Thus, because of accountability effects, we propose policy makers face a dilemma: prevent terrorism using normative methods that incorporate the likelihood of attack or prevent blame by preventing terrorist attacks the public find most blameworthy.  相似文献
