Cultivating Change: The Relationship Between Organizational Culture, Leadership Style and Communication Style with Organizational Change

This paper presents a quantitative study on organizational change and how culture, leadership, and communication styles are related to different types of change. The objective was to understand these relationships and to provide insight for future applications centered on enabling organizational change. Respondents (N=411) from multiple organizations participated in evaluating preferences for culture, leadership and communication styles in response to different change scenarios. The study features four control groups, each representing various types of organizational change. Responses were evaluated using the Organizational Culture Assessment Instrument (OCAI) to identify individual cultural preferences and seven-point Likert-type questionnaires for leadership and communication style preferences. The results of the study were unexpected by showing a lack of statistically significant relationships between each of the variables. However, the research did show a correlation between the preference of “open” communication styles with all four culture types. Several reasons for this lack of significance are discussed under future research, which may provide further insight as to how attitudes toward change might affect a respondent’s view of culture, leadership, and communication

Fandom’s paratextual memory : remembering, reconstructing, and repatriating “lost” Doctor Who

In this article, we aim to bring fan studies and memory studies into greater dialogue through the concept of “paratextual memory”. For media fans, paratextual memory facilitates a sense of “having been there” at key moments of T.V. broadcasting, sustaining fan authenticity and status. We focus on B.B.C. T.V.’s science fiction series Doctor Who (1963–) as a case study due to the fact that the program's “missing episodes” (wiped by the B.B.C.) have been reconstructed by fans through “remixes” of off-air sound recordings and “tele-snap” visual records. Unusually, then, fans’ paratextual memory and related forms of productivity have taken the place of archived television. We go on to address how fan-archivists and entrepreneurs have sought to recover and repatriate “lost” Doctor Who. Processes of fannish paratextual memory typically draw on heritage discourses to valorize “classic” Doctor Who, and fans’ paratextual memory has thus fed into the B.B.C.’s recommodification of “archive” T.V

Farm-level risk factors for Fasciola hepatica infection in Danish dairy cattle

Recent studies suggest that liver fluke (Fasciola hepatica) infections in cattle have increased in Denmark in recent years. This study aimed to identify potential farm level risk factors for liver fluke infection in Danish dairy farms using two different diagnostic methods. Based on liver condemnation data of all individual cattle slaughtered in Denmark, 145 and 77 farms were selected as cases and matched controls. The selection criteria were; 1) minimum 50 animals were slaughtered in 2013, 2) minimum three cases of liver condemnation due to liver flukes in 2013 (case) / no history of liver condemnation due to liver flukes for the last three years (control), and 3) control farms were located within 10 km from the case farms. Bulk tank milk (BTM) samples from the farms were analysed using enzyme-linked immunosorbent assay (ELISA), and telephone interviews were used to obtain information on the type of production, the farmers’ knowledge about liver fluke infection, grazing pattern, anthelmintic treatments and management routines. Preliminary results based on 132 case and 64 control farms indicate that grazing was significantly associated with liver fluke infection (p=0.006). However, in 12 case herds, grazing was not applied (all-in systems), suggesting indoor rearing does not completely prevent liver fluke infections, although misdiagnosis or incorrect registration at slaughter is possible. The percentage of farms allowing heifers to graze on wet areas was significantly higher in case than control farms (p<0.001). Using grazing for heifers and drinking from natural waterways were associated with liver fluke infections (p=0.07 and p=0.01). Approximately 30% of case farms tried actively to avoid infection by anthelmintic treatment or preventive management measures. The prevalences of liver flukes estimated by BTM ELISA were 75% and 12.5% for case and control groups, respectively. The negative ELISA results in some of the case herds may be due to their low in-herd prevalence, but it is still under investigation. Based on the risk analysis, we expect grazing management can be improved on many infected farms as part of the control of liver fluke. The substantial discrepancy between different diagnostic methods should be taken into account for future studies

Hot of Not: Physiological versus Meteorological Heatwaves-Support for a Mean Temperature Threshold

The aim of this study was to determine whether a revised heat warning threshold provides an enhanced predictive tool for increases in Emergency Department heat-related presentations in Canberra, Australia. All Emergency Department triage records containing the word "heat", as well as those diagnosing a heat related illness for the summer periods 2013/2014, 2014/2015, and 2015/2016 were searched. Then a medical record review was conducted to confirm that the patient's presentation was related to environmental heat, which was defined by the final clinical diagnosis, presentation complaint and details of the patient's treatment. Researchers then compared this presentation data, to a mean threshold formula. The mean threshold formula included the past three consecutive daily mean temperatures and the last measured temperature upon presentation. This formula was designed to take into account the variance of night-time lows, with concurrent daily ambient temperatures, and was used to determine whether there was a correlation between heat-related presentations and increasing mean temperatures. Heat-related presentations appeared to occur when the mean threshold temperature reached 25 °C (77 °F), with significant increases when the mean threshold reached 30 °C (86 °F). These results confirm that a mean temperature of 30 °C corresponds to a relevant local public health heat-related threat

Effect of the stellar spin history on the tidal evolution of close-in planets

We investigate how the evolution of the stellar spin rate affects, and is affected by, planets in close orbits, via star-planet tidal interactions. To do this, we used a standard equilibrium tidal model to compute the orbital evolution of single planets orbiting both Sun-like stars and 0.1 M\odot M-dwarfs. We tested two stellar spin evolution profiles, one with fast initial rotation (P=1.2 day) and one with slow initial rotation (P=8 day). We tested the effect of varying the stellar and planetary dissipation and the planet's mass and initial orbital radius. Conclusions: Tidal evolution allows to differentiate the early behaviors of extremely close-in planets orbiting either a rapidly rotating star or a slowly rotating star. The early spin-up of the star allows the close-in planets around fast rotators to survive the early evolution. For planets around M-dwarfs, surviving the early evolution means surviving on Gyr timescales whereas for Sun-like stars the spin-down brings about late mergers of Jupiter planets. In light of this study, we can say that differentiating between one spin evolution from another given the present position of planets can be very tricky. Unless we can observe some markers of former evolution it is nearly impossible to distinguish the two very different spin profiles, let alone intermediate spin profiles. Though some conclusions can still be drawn from statistical distributions of planets around fully convective M-dwarfs. However, if the tidal evolution brings about a merger late in its history it can also entail a noticeable acceleration of the star in late ages, so that it is possible to have old stars that spin rapidly. This raises the question of better constraining the age of stars
