A sense of power and system justification: Reexamining van der Troon et al. (2015)

We conducted two studies reexamining the findings of van der Toorn et al. (2015) that a sense of powerlessness fosters system justification (SJ). In Study 1, we used the Sense of Power Scale (Anderson et al., 2012) and found that a sense of powerfulness as well as a sense of powerlessness are positively associated with SJ. In Study 2, after priming participants with a feeling of powerfulness vs. powerlessness, we investigated the mediating effects of emotions on the relationship between sense of power and SJ. Although participants experienced positive emotions in the Powerful condition and negative emotions in the Powerless condition, we did not find any significant effects of emotions on SJ. Further studies are needed to investigate the relationship between a sense of power and SJ using more sophisticated methods.本論文は，2019年度に広島大学教育学部で開講された心理学課題演習において，第1著者の指導により第2著者から第5著者が実施した研究をもとに執筆したものである。研究の一部は第2著者から第5著者により中国四国心理学会第75回大会学部生研究発表会において報告された。また，本研究はJSPS科研費JP18K03007 の助成を受けた

Infection risk in hemodialysis patient

Chronic care patients undergoing hemodialysis for treatment of end-stage renal failure experience higher rates of bloodstream-associated infection due to the patients' compromised immune system and management of the bloodstream through catheters. Staphylococcus species are a common cause of hemodialysis catheter-related bloodstream infections. We investigated environmental bacterial contamination of dialysis wards and contamination of hemodialysis devices to determine the source of bacteria for these infections. All bacterial samples were collected by the swab method and the agarose stamp method. And which bacterium were identified by BBL CRYSTAL Kit or 16s rRNA sequences. In our data, bacterial cell number of hemodialysis device was lower than environment of patient surrounds. But Staphylococcus spp. were found predominantly on the hemodialysis device (46.8%), especially on areas frequently touched by healthcare-workers (such as Touch screen). Among Staphylococcus spp., Staphylococcus epidermidis was most frequently observed (42.1% of Staphylococcus spp.), and more surprising, 48.2% of the Staphylococcus spp. indicated high resistance for methicillin. Our finding suggests that hemodialysis device highly contaminated with bloodstream infection associated bacteria. This study can be used as a source to assess the risk of contamination-related infection and to develop the cleaning system for the better prevention for bloodstream infections in patients with hemodialysis
