Data from: Factors associated with possession of accurate knowledge regarding occupational health management among operations leaders of radiation decontamination workers in Fukushima, Japan: a cross-sectional study
Objectives: An operations leader (OL) takes an important role in occupational health management for radiation decontamination workers in Japan, and candidates for the position must participate in a training session to acquire the necessary knowledge as required by law. However, it has not been clarified whether the candidates for the OL position actually possess accurate knowledge regarding occupational health management for such work after the training session. We therefore aimed at examining the current occupational health management knowledge among the candidates and investigating factors related to the knowledge, with hypothesis that possession of accurate knowledge is associated with prior experience of having worked in radiation decontamination. Design: A cross-sectional study. Setting: The training sessions held by Fukushima Prefecture Labor Standard Associations in Fukushima, Japan, in 2017. Participants: Eighty male candidates participated in the training sessions. Outcome: The number/proportion of correct answers to the questions regarding occupational health management such as those on working environment management, control of operations, and health management. Results: The proportion of those who possessed accurate knowledge regarding working environment management, control of operations, and health management, was 68.8%, 55.0%, and 51.2%, respectively. Experience of radiation decontamination work was associated with the possession of inaccurate knowledge regarding working environment management (OR 0.140 [95% CI 0.042, 0.464]), and the uncertainty of future radiation decontamination work schedules in difficult-to-return zones was associated with the possession of accurate knowledge regarding health management (OR 4.382 [95% CI 1.525, 12.591]). Conclusions: Previous experience in radiation decontamination work may hinder the ability to acquire accurate information regarding working environment management among candidates for an OL position. To promote adequate occupational health management for radiation decontamination workers, it is required to establish an effective instructional method for the OL candidate training sessions with consideration of previous relevant experience.
Data from: Tight knit under stress: colony resilience to the loss of tandem leaders during relocation in an Indian ant
The movement of colonies from one nest to another is a frequent event in the lives of many social insects and is important for their survival and propagation. This goal-oriented task is accomplished by means of tandem running in some ant species, such as Diacamma indicum. Tandem leaders are central to this process as they know the location of the new nest and lead colony members to it. Relocations involving targeted removal of leaders were compared with unmanipulated and random member removal relocations. Behavioural observations were integrated with network analysis to examine the differences in the pattern of task organization at the level of individuals and that of the colony. All colonies completed relocation successfully and leaders who substituted the removed tandem leaders conducted the task at a similar rate having redistributed the task in a less skewed manner. In terms of network structure, this resilience was due to significantly higher density and outcloseness indicating increased interaction between substitute leaders. By contrast, leader–follower interactions and random removal networks showed no discernible changes. Similar explorations of other goal-oriented tasks in other societies will possibly unveil new facets in the interplay between individuals that enable the group to respond effectively to stress.
Data from: Leader preference in Neoconocephalus ensiger katydids: a female preference for a non-heritable male trait
Leader preferences, which result in greater mating success of males that produce their signals just ahead of those of their neighbors, are common in acoustically communicating insects and anurans (e.g. Whitney and Krebs 1975, Greenfield and Roizen 1993, Grafe 1996, Römer et al. 1997, Greenfield et al. 2004). These preferences are unusual in that they do not act on a property of the male signal itself but rather on its timing relative to that of other males (Snedden and Greenfield 1998), making the relationship between female preferences and male signal traits particularly complex. Leader preferences have been studied from several perspectives: their strength, their effect on male interactions, and their evolutionary origins (e.g. Greenfield and Roizen 1993, Grafe 1999, Römer et al. 2002, Hartbauer et al. 2006, Richardson et al. 2008, Hartbauer 2014, Party et al. 2014, Party et al. 2015).

Interactions and Multifrequency Radiation Characteristics of Bidirectional Leaders in Altitude-Triggered Lightning
<p><span>Altitude-triggered lightning provides favorable conditions for the research of bidirectional leader system. In the summer of 2023, altitude-triggered lightning experiment was conducted on the Field Experiment Base on Lightning Sciences, China Meteorological Administration. <a name="_Hlk162343222"></a>The multifrequency radiation characteristics of bidirectional leaders and the interactions of both ends during the propagation are analyzed. Specifically, the discharge processes relevant to LF-MF magnetic radiations of bidirectional leaders can be revealed by high-speed optical images in altitude-triggered lightning, and all these LF-MF radiations correspond to VHF radiations associated with bidirectional leaders well. Unlike the close correlation between the LF-MF radiation strengths and the discharge intensities, <a name="OLE_LINK10"></a>the VHF radiation strengths vary greatly even for similar discharge events, since VHF radiations correspond to microscopic random breakdown processes. Furthermore, the changes of leader speed and channel brightness before and after the bidirectional leaders indicate that <span>the development of the two ends of bidirectional leads is mutually reinforcing.</span></span></p>
