Extensive debate and criticism of potentially common, yet questionable research practices that lead to biased findings within social and health sciences has emerged over the last decade. These challenges likely apply to educational psychology, though the field has been slow to address them. This article discusses current research norms, strategic solutions proposed under the broad rubric of “Open Science”, and the implications of both for the way research syntheses in educational psychology are conducted and the quality of the information they produce. Strategies such as preregistration, open materials and data, and registered reports stand to address significant threats to the validity of research synthesis. These include challenges associated with publication, dissemination, and selective reporting biases, comprehensive information retrieval, and opportunities to execute unique analytic approaches. A final issue is the development of parallel solutions that address biases specific to the decision making of researchers conducting and evaluating research syntheses.

Pre-registration and registered reports are two of the most promising open science practices for increasing transparency in the scientific process. Pre-registration involves publishing a timestamped record of a study design, ideally before data collection and analysis, so that research consumers can discern which analytic decisions were set a priori and which were changed after seeing data. Registered reports take the idea of pre-registration one step further, and provide peer review at the pre-registration stage. Researchers submit a Phase I manuscript that contains the introduction, background and context, and methods section of a study, and these Phase I manuscripts are peer reviewed. If reviewed positively, manuscripts are given in-principle acceptance, where the editors agree that if the researchers conduct the study as pre-registered--or document the deviations from their plan--the study will be published without regard for the direction or magnitude of findings. In this manner, studies are judged by whether they address important questions and use well-designed methods, not on the basis of reaching specific benchmarks for significance or effect size. This article illustrates the emerging range of approaches to pre-registration and registered reports with examples from a variety of studies and from the first special issue in educational research devoted to Registered Reports.PLEASE DO NOT CITE YET:This article is part of a forthcoming journal Special Issue on Open Science in Education and currently under review.

Over Time

In principle, a school atlas presents the status quo at a given moment, but when it is regarded as a serial work regularly updated, and when, thanks to digital technologies, the same maps in consecutive atlas editions can be compared one to another, then movement over time is visualized. With a customized tool, one may pick one particular map in the nth edition of the atlas and then compare it to the same map in the previous or the next edition on a shared screen, to find out what changes occurred within a specific time frame. Examples of possible applications at different scales show that each map type (because of the kind of symbols used) and each scale level have their own types of stories unfolding.

Micromechatronics has become a key issue in engineering. Robotics and mechatronics are a global concern. Micromechatronics contributes especially to the development of electrical and mechanical systems through miniaturization and advanced functions. Micromechatronics was defined by Prof. Fukuda, Prof. Fujita et. al in the 1980's. In 1980's, Microelectromechanical Systems (MEMS) was developed in the USA and then expanded to Japan and Germany. In the same time frame, devices based on precious machining technology were miniaturized in Japan and Switzerland as Michromachine. MEMS combines electronics and mechatronics and promotes new-conceptual devices such as intellectual sensors, e.g., pressure and acceleration sensors. Precious machining has improved manufacturing and achieved the find control. Thorough these development, Micromechatronics was born as an integrated technology. This special issue introduces basic technologies and applications of micromechatronics, which includes such vital technologies as mechanical, electric, and electrical engineering, machining, and MEMS. This issue, which features several topics on micromechatronics, will give readers a welcome chance to acquaint themselves with state-of-the-art information on micromechatronics. This issue contains nine technical papers on micro robots, intelligent microsensors, and their applications, together with related letters. It opens with a paper on microsensors by Fujiyoshi et al. and the application of miniaturized motors to a robotic hand by Nishibori et al. Included also are articles on micro robots by Aoyama, Torii, Wakimoto and Guo, work on unique micromanipulation systems by Nakamura et al., and the application of micro units to robotic systems by Yamada et al. Letters discuss objectives and achievements of micro robot contests held in Japan that serve to popularize and disseminate unique mechanisms and new concepts in this exciting field. I am certain this issue will provide readers with information that is both interesting and informative. In closing, I would like to thank the authors, members of the editorial board, and the publisher, without whose hard work and careful consideration this issue would not have been possible.

In this paper, we correlate the internal stress and the characteristics of a vibrational mode in wet foam. Using microscope images, we estimate the average size of the bubbles in wet foam, at specific time intervals, over a duration of 24 h. Raman spectra are also recorded at the same time intervals, over the same time frame. We show that the internal stress, originated from the microscopic structural change of foam with aging, can be related to the observed Raman shift of the low-frequency methylene rocking mode of the constituent surfactant molecules in foam. In this paper, we also show the capability of the Raman spectroscopy to reveal the crystallinity in foamy materials, when studied for a longer period of time.

This paper draws out lessons from the special issue, laying out elements of research agenda on climate policy entrepreneurship. First, I offer an expanded definition of entrepreneurship, which distinguishes between the entrepreneurs themselves and the strategies they employ. Further refinements of the concept of entrepreneurship should specify other relevant dimensions of variation, such as the desired outcome, and the expected time frame in which it is to be achieved. I then present a simple causal model of entrepreneurship to facilitate future comparative research. Based on the papers in the special issue, I derive several testable hypotheses for future research. Finally, I argue that we must also consider the “expansive effects” of policy entrepreneurs: the extent to which their actions lead to changes beyond those intended. I offer some approaches to begin to study these broader effects.

In education, scientific research should play an important role in improving learner outcomes by informing and enhancing policy and practice. However, a substantial gap exists between research and practice in the field. To close this gap, researchers in educational psychology can apply open-science practices to increase the credibility, impact, and equity of their research. In this article, we examine three open-science practices -- open data and code, open access and preprints, and crowdsourcing -- that are well-suited to foster credibility, impact, and equity of research. For each open-science practice, we briefly discuss what the practice is and how it works, its primary benefits, some important limitations and challenges, and a thorny issue related to the practice.

Abstract The positivity effect (PE) refers to age-related enhancement in memory for positive information or decreased memory for negative information. The PE is thought to be the result of age-associated shifts in motivational goals towards enhancing well-being. Research has demonstrated the PE in laboratory settings, and a meta-analysis showed that the PE was most robust in conditions with fewer instructions/constraints (Reed et al., 2014). Findings related to the PE in autobiographical memory (AM) are mixed. Goals of the current study include examining 1) whether the PE was evident across four increasingly restrictive AM conditions (involuntary AMs, voluntary AM with no constraints, voluntary AM within a specific time frame, voluntary AM within a specific time frame and related to a specific cue word), and 2) whether available cognitive resources (assessed with the Stroop task and a trail-making test) influence the PE, since cognitive control is essential for achieving goals. Participants (N=126) completed the shortened Memory Experiences Questionnaire for each memory, which assesses several phenomenological characteristics, including memory valence. There were no significant differences in memory valence between the younger (n=69, ages 18-34) and older adult (n=57; ages 60-85) groups for involuntary AMs or the less constrained voluntary AMs, but there was a significant difference for the most constrained AM wherein older adults rated their AMs as more positive than younger adults. Performance on cognitive control measures did not influence the AM valence. These results highlight the importance of considering the effects of type of stimuli and instructions when studying the PE.

Manufacturing companies have responsibility to participate in reducing the environmental problems impacted by their operations. This study aims to identify the efforts of Indonesian manufacturing companies in abating environmental impacts caused by their production processesand to understand the behaviour of manufacturing companies in providing environmental information to their stakeholders. The population of this study are all manufacturing companies listed on the Indonesia Stock Exchange (IDX) and PROPER in 2012-2016. By employing purposive sampling, the study collected 135 data from 27 companies. On average, Indonesian manufacturing companies earned grade of 3 (Blue) in implementing PROPER. The extent of environmental disclosure is only around 38%. Environmental disclosure of manufacturing companies is influenced by rete of environmental performance and company size. Environmental performance is significantly affected by profitability and size. Leverage does not influence environmental performance, environmental disclosure, and profitability. The level of environmental disclosure is mostly descriptive and does not have a specific time frame. Indonesian manufacturing companies should improve their environmental performance and environmental disclosure.
