AbstractIn this essay, we closely examine three aspects of the Reporting Guidelines for this journal, as described by Gerber et al. (2014, Journal of Experimental Political Science 1(1): 81–98) in the inaugural issue of the Journal of Experimental Political Science. These include manipulation checks and when the reporting of response rates is appropriate. The third, most critical, issue concerns the committee's recommendations for detecting errors in randomization. This is an area where there is evidence of widespread confusion about experimental methods throughout our major journals. Given that a goal of the Journal of Experimental Political Science is promoting best practices and a better understanding of experimental methods across the discipline, we recommend changes to the Standards that will allow the journal to play a leading role in correcting these misunderstandings.

AbstractBecause political science draws heavily from other disciplines—psychology and economics—in its use of experimental methods, we often fail to note how each experimental tradition developed in ways, while serving those field's primary goals, that often present contradictory imperatives that may not serve political science equally well. I provide a brief history of experimental traditions in psychology and economics, and then suggest, in all humility, an integrated set of best practices for the use of experiments in political science.

There are many roles that design can play in organisations. It can be source of good marketing strategy, and designer by himself can be a promotional tool for a company. Thanks to those actions companies can gain publicity, media attention and good PR.On the second level, design can be perceived as ‘process of making things better’. In this case companies can achieve more effective product development process, new tools and technologies.On the third level we have the situation when designer work alongside with company managers with the whole business concept. At this level, designers’ work looks more like a brand consultant, a strategist. In this approach design should be reflecting certain brand name and brand values.As our study presented, Swedish companies operate on those two, higher levels, while Polish still limit the scope of design. We strongly believe, that Polish companies, as they gain more experience with design activities, will be more likely to perceive design in this more mature approach. In the meantime, presenting best practices from companies from other, more mature countries could be a good way of promoting design as a strategic asset rather than promotional tool. We believe that in order to fasten this process, Polish companies should as follows:1. Work more often with external and foreign designers;2. Expand the area of designer responsibilities in companies;3. Place the responsibility for design in hands of professional design managers.

Malaysia is in the process of liberalising its electricity supply industry (ESI) further, with the second reform series announced in September 2018. If everything goes as planned, Malaysia would be the third country in the Association of Southeast Asia Nations (ASEAN) to have a fully liberalised ESI after the Philippines and Singapore. A number of initiatives have been in the pipeline to be executed and a lot more will be planned. At this juncture, it is important for Malaysia to look for the best practices and lessons that can be learnt from the experience of other countries that have successfully liberalised their ESIs. Being in the same region, it is believed that there is a lot that Malaysia can learn from the Philippines and Singapore. This paper therefore presents and deliberates on the chronological development of the countries’ progressive journeys in liberalising their ESIs. The aim is to discern the good practices, the challenges as well as the lessons learnt from these transformations. Analysis is being made and discussed from the following four perspectives; legislative framework, implementation phases, market components and impact on renewable energy penetration. Findings from this study would provide useful insight for Malaysia in determining the course of actions to be taken to reform its ESI. Beyond Malaysia, the findings can also serve as the reference for the other ASEAN countries in moving towards liberalising their ESIs.

The bulk of research on academic rankings is policy-oriented, preoccupied with ‘best practices’, and seems incapable of transcending the normative discourse of ‘governance’. To understand, engage, and properly critique the operation of power in academic rankings, the rankings discourse needs to escape the gravity of ‘police science’ and embrace a properly political science of ranking. More specifically, the article identifies three pillars of the extant research from which a departure would be critically fruitful – positivism, managerialism, institutionalism – and then goes on to outline three aspects of rankings that a critical political analysis should explore, integrate, and develop into future research from the discourses of critical theory – arkhè, dispositif, and dialectik.

This study assessed differences in response rates to a series of three-wave mail surveys when amiable or insistently worded postcards were the third wave of the mailing. Three studies were conducted; one with a sample of 600 health commissioners, one with a sample of 680 vascular nurses, and one with 600 elementary school secretaries. The combined response rates for the first and second wave mailings were 65.8%, 67.6%, and 62.4%, respectively. A total of 308 amiable and 308 insistent postcards were sent randomly to nonrespondents as the third wave mailing. Overall, there were 41 amiable and 52 insistent postcards returned, not significantly different by chi-square test. However, a separate chi-square test for one of the three studies, the nurses' study, did find a significant difference in favor of the insistently worded postcards.

One of the plants that are often used in traditional medicine is the fruit of pumpkin used to treat hepatitis manner pumpkin fruit cut into small pieces and then steamed, then eaten .Pumpkin fruits contain active compounds such as saponins, tannins, flavonoids and beta-carotene. Beta-carotene is converted in the body into vitamin A is beneficial for the growth, maintenance of body tissues and to reduce the risk of cancer and heart disease. This study aims to determine pumpkin juice has a hepatoprotective activities on liver function by looking at parameters SGPT and SGOT in rats after induced CCl4. Type of experimental research using True Experimental research design design. Test animals were grouped into 5 groups, each group consisting of 3 rats. The first group of positive control (Methicol®), the second group negative control (CCl4), the third group of pumpkin juice 25%, the fourth group of pumpkin juice 50%, the fifth group of pumpkin juice 75%. From the results of this study concluded that the pumpkin juice 75% effective as a hepatoprotective by looking at parameters SGPT is 48 U/liter and SGOT is 66 U/liter in rats after induced carbon tetrachloride

Writing is still considered as a difficult skill in language learning by Indonesian students. For that reason, it is urgent for teacher to seek for interesting ways to teach writing in the classroom. This study examines the effectiveness of  the use of peer feedback technique to improve students’ skill in writing descriptive paragraph. Some studies have proved the effectiveness of the technique to improve students’ writing skill. The study employs experimental research in which one class of 20 students is  taught to write narrative paragraph and correct their paragraph using peer feedback technique. The result of the study shows that the technique improves the students writing skill in narrative writing, however the scores are not significant. This suggests that there is a factor that affects the result of the teaching using peer feedback, and it is the less time of treatment which is indicated as the factor.

This report summarizes the primary output of this project, a book of COVID-era street reconfiguration case studies called Rethinking Streets During COVID-19: An Evidence-Based Guide to 25 Quick Redesigns for Physical Distancing, Public Use, and Spatial Equity. COVID-era needs have accelerated the process that many communities use to make street transformations due to: a need to remain physically distanced from others outside our immediate household; a need for more outdoor space close to home in every part of every community to access and enjoy; a need for more space to provide efficient mobility for essential workers in particular; and a need for more space for local businesses as they try to remain open safely. This project is the third in a series of NITC-supported case study books on best practices in street reconfigurations for more active, sustainable, and in this case, COVID-supportive uses. The full, 154-page book is available for free download from the National Institute for Transportation and Communities (NITC).
