Unconditional Preference

Existing research suggests that voters tend to respond positively to legislator independence due to two types of mechanism. First, dissent has an indirect effect, increasing a legislator’s media coverage and personal recognition among constituents (profile effects). Secondly, constituents react positively to dissent when this signals that the legislator has matching political or representational preferences (conditional evaluation). This article presents a third effect: dissent acts as a valence signal of integrity and trustworthiness. Consistent with the valence signalling mechanism, it uses new observational and experimental evidence to show that British voters have a strong and largely unconditional preference for legislators who dissent. The findings pose a dilemma for political systems that rely on strong and cohesive parties.

While effective preventive measures against COVID-19 are now widely known, many individuals fail to adopt them. This paper provides experimental evidence about one potentially important driver of compliance with social distancing: social norms. We asked each of 23,000 survey respondents in Mexico to predict how a fictional person would behave when faced with the choice about whether or not to attend a friend's birthday gathering. Every respondent was randomly assigned to one of four social norms conditions. Expecting that other people would attend the gathering and/or believing that other people approved of attending the gathering both increased the predicted probability that the fictional character would attend the gathering by 25% in comparison with a scenario where other people were not expected to attend nor to approve of attending. Our results speak to the potential effects of communication campaigns and media coverage of, compliance with, and normative views about COVID-19 preventive measures. They also suggest that policies aimed at modifying social norms or making existing ones salient could impact compliance.

Hostile Media

Previous research suggests that the antagonists in conflicts are influenced by their perceptions of hostile media coverage and presumptions of media effects. Research so far has concentrated on presumed media influences on the general public. This study concentrates on presumed media influences on the conflicting parties. It tests how hostile media perceptions and presumptions of media effects on the conflicting parties affect the antagonists’ acceptance of an uncivil and uncompromising style of public communication. In the context of the German controversy over aircraft noise, online surveys of 82 (47%) opponents of aircraft noise and 48 (33%) proponents of air traffic were conducted. Hostile media perceptions have no direct but an indirect effect on antagonists’ intentions to communicate. They strengthen both parties’ beliefs that the media make the protesters against aircraft noise more extreme. This, in turn, increases both parties’ acceptance of incivility in the public dispute.

In addition to being formally defined as a pandemic, COVID-19 has been classified as an “infodemic” and “(mis)infodemic.” As an “infodemic,” the information environment on COVID-19 is constantly evolving, with emerging scientific findings, political responses, media coverage, and individual impressions all shared on social media. Initial positions on behaviors and potential treatments were presented and then discarded because of low efficacy or improper research procedures. Further, there has been a fragmented geopolitical response with differing political systems exhibiting varying approaches to decision making and health outcomes, which has lead to confusion of the public. As a “misinfodemic,” COVID-19 discussions have also attracted actors seeking to share misinformation enabled and exacerbated by social media networks, which include willful distortions as well as conspiracy theories. Combined, this (mis)infodemic can change risk perceptions of travel, resulting in travel patterns based on technological, regulatory, and perceived behavioral homophily.

Nuclear power has always been a controversial issue since it was discovered as a source of power for civil use. Despite being a global phenomenon, nuclear power is viewed differently around the world, and consequently, different discourses have had different outcomes. This study does a comparative analysis of nuclear power discourses between India and Russia, two countries of distinct political systems. This study analyses the media coverage and content of the main discourse themes in India’s and Russia’s print media from March 2011 to March 2019. The study finds that in both countries, despite their different political set-ups, nuclear power discourse has a pro-nuclear character.

Abstract We fully support dissociating the subjective experience from the memory contents in recognition memory, as Bastin et al. posit in the target article. However, having two generic memory modules with qualitatively different functions is not mandatory and is in fact inconsistent with experimental evidence. We propose that quantitative differences in the properties of the memory modules can account for the apparent dissociation of recollection and familiarity along anatomical lines.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.

Ultrathin Sections

It is believed by the authors, with supporting experimental evidence, that as little as 0.5°, or less, knife clearance angle may be a critical factor in obtaining optimum quality ultrathin sections. The degree increments located on the knife holder provides the investigator with only a crude approximation of the angle at which the holder is set. With the increments displayed on the holder one cannot set the clearance angle precisely and reproducibly. The ability to routinely set this angle precisely and without difficulty would obviously be of great assistance to the operator. A device has been contrived to aid the investigator in precisely setting the clearance angle. This device is relatively simple and is easily constructed. It consists of a light source and an optically flat, front surfaced mirror with a minute black spot in the center. The mirror is affixed to the knife by placing it permanently on top of the knife holder.

Cilia And Flagella

In 1959, Afzelius observed the presence of two rows of arms projecting from each outer doublet microtubule of the so-called 9 + 2 pattern of cilia and flagella, and suggested a possibility that the outer doublet microtubules slide with respect to each other with the aid of these arms during ciliary and flagellar movement. The identification of the arms as an ATPase, dynein, by Gibbons (1963)strengthened this hypothesis, since the ATPase-bearing heads of myosin molecules projecting from the thick filaments pull the thin filaments by cross-bridge formation during muscle contraction. The first experimental evidence for the sliding mechanism in cilia and flagella was obtained by examining the tip patterns of molluscan gill cilia by Satir (1965) who observed constant length of the microtubules during ciliary bending. Further evidence for the sliding-tubule mechanism was given by Summers and Gibbons (1971), using trypsin-treated axonemal fragments of sea urchin spermatozoa. Upon the addition of ATP, the outer doublets telescoped out from these fragments and the total length reached up to seven or more times that of the original fragment. Thus, the arms on a certain doublet microtubule can walk along the adjacent doublet when the doublet microtubules are disconnected by digestion of the interdoublet links which connect them with each other, or the radial spokes which connect them with the central pair-central sheath complex as illustrated in Fig. 1. On the basis of these pioneer works, the sliding-tubule mechanism has been established as one of the basic mechanisms for ciliary and flagellar movement.
