The excedances and descents of bi-increasing permutations
Starting from some considerations we make about the relations between certain
difference statistics and the classical permutation statistics we study
permutations whose inversion number and excedance difference coincide. It turns
out that these (so-called bi-increasing) permutations are just the 321-avoiding
ones. The paper investigates their excedance and descent structure. In
particular, we find some nice combinatorial interpretations for the
distribution coefficients of the number of excedances and descents,
respectively, and their difference analogues over the bi-increasing
permutations in terms of parallelogram polyominoes and 2-Motzkin paths. This
yields a connection between restricted permutations, parallelogram polyominoes,
and lattice paths that reveals the relations between several well-known
bijections given for these objects (e.g. by Delest-Viennot,
Billey-Jockusch-Stanley, Francon-Viennot, and Foata-Zeilberger). As an
application, we enumerate skew diagrams according to their rank and give a
simple combinatorial proof for a result concerning the symmetry of the joint
distribution of the number of excedances and inversions, respectively, over the
symmetric group.Comment: 36 page
Inaccuracies and exaggerations (Health Coverage)
Exaggerated or simplistic media coverage on health issues is often blamed for affecting public health (Sumner et al., 2016). For example, MacDonald and Hoffman-Goetz (2002) have shown that cancer information in newspapers frequently contained inaccuracies in the past. However, more recent findings suggest that inaccuracies, like an oversimplified language, and exaggerations are already present in health news press releases (Brechman et al., 2009; Sumner et al., 2016).
Field of application/theoretical founation:
Health communication, science communication

Authors: Jean M- Brechman, Chul-joo Lee, Joseph N. Cappella
Research question: The study explores the communication of genetic science to the lay public. To address this issue, this study compares the presentation of genetic research relating to cancer outcomes and behaviors (i.e., prostate cancer, breast cancer, colon cancer, smoking and obesity) in the press release (N = 23) to the presentation in the subsequent news coverage (N = 71).
Object of analysis: The total sample included N = 71 articles on gene/cancer-outcome discoveries from major U.S. newspapers (no further information) as well as all corresponding press releases (N = 23) from institution web sites and EurekAlert! or PRNewswire (electronic archives of releases for science writers).
Time frame of analysis: July 2004 to June 2007
Info about variables
Variables: Coding schema to capture conceptual and contextual differences between information presented in the press release and information presented in related news coverage; codes used to make these distinctions included overgeneralization/ simplification, assimilation of speculation into fact, contradiction, and level of specificity/qualifying information.
Reliability: In order to assess reliability, five cases containing 109 claims were coded by two independent coders. Overall agreement was 79.8%.
Level of analysis: Central claims on genetic research relating to cancer outcomes and behaviors in press release and media articles
Information on MacDonald & Hoffman-Goetz, 2009
Authors: Megan M. MacDonald, Laurie Hoffman-Goetz
Research question: The purpose of this study was to determine whether cancer articles in Canadian newspapers provide accurate cancer information relative to the original scientific sources of the information and the extent of mobilizing information about cancer prevention and treatment. A second objective was to determine whether newspaper circulation size influenced the accuracy of reporting of cancer information.
Object of analysis: From a total of 38 newspapers serving Ontario, the top 5 and bottom 5 newspapers in terms of circulation were identified for extreme group comparisons. All articles including the term “cancer” in the headline were extracted and a random sampling led to a total sample of N = 306 articles, including The Toronto Star (n = 63), The Ottawa Citizen (n = 49), The Hamilton Spectator (n = 53), The London Free Press (n = 42) and The Windsor Star (n = 30) as top 5 newspapers as well as. the Pembroke Daily Observer (n = 12), Lindsay Daily Post (n = 20), Northern Daily News (Kirkland Lake) (n = 12), Cobourg Daily Star (n = 10) and The Daily Miner & News (Kenora) (n = 15) as bottom 5.
Time frame of analysis: 1991
Info about variables
Variables: The accuracy of each article was assessed using the following criteria: misleading title, treating speculation as fact, erroneous information, omitting important results and omitting qualifications or caveats to findings.
Reliability: The articles were coded separately by the researchers using the identified criteria. Where discrepancies occurred in coding results, these were discussed until a consensus was met. Consensus discussions occurred early in data collection to allow this process to inform and direct future coding (no further information provided).
Level of analysis: article

Authors: Petroc Sumner, Solveiga Vivian-Griffiths, Jacky Boivin, Andy Williams, Christos A Venetis, Aimée Davis, Jack Ogden, Leanne Whelan, Bethan Hughes, Bethan Dalton, Fred Boy, Christopher D Chambers
Research question: The study examines whether the press release or the news article are the source of distortions, exaggerations, or changes to the main conclusions drawn from research that could potentially influence a reader’s health related behaviour.
Object of analysis: Press releases (n = 462) on biomedical and health related science issued by 20 leading UK universities, alongside their associated peer reviewed research papers and news stories (n = 668).
Time frame of analysis: 2011
Info about variables
Variables: Taking the peer reviewed paper as a baseline, the authors sought cases where news stories offered advice to readers, made causal claims, or inferred relevance to humans beyond (or different to) that stated in the associated peer reviewed paper. Given the likelihood that some statements in journal articles themselves would be considered exaggerated by other scientists in the specialty, the overall levels of measured exaggeration are likely to be underestimates. The authors then asked whether such discrepancies were already present in the corresponding press release. For example, if a study reported a correlation between stress and wine consumption and the news story claimed that wine causes stress, what did the press release say? Similarly, if a news story claimed a new treatment for humans but the study was on rodents, what did the press release say?

Authors: Petroc Sumner, Solveiga Vivian-Griffiths, Jacky Boivin, Andrew Williams, Lewis Bott, Racel Adams, Christos A Venetis, Aimée Davis, Leanne Whelan, Bethan Hughes, Christopher D Chambers
Research question: Recent findings suggested many exaggerations in the portrayal of health information were already present in university press releases, which scientists approve. Surprisingly, these exaggerations were not associated with more news coverage. This study examines whether these two controversial results also arise in press releases from prominent science and medical journals.
Object of analysis: press releases (n = 534) on biomedical and health-related science issued by leading peer-reviewed journals. The authors similarly analysed the associated peer-reviewed papers (n = 534) and news stories (n = 582).
Time frame of analysis: 2011
Info about variables
Variables: The process of data extraction and analysis was identical to that in Sumner et al. (2014).

Stigmatization (Health Coverage)
Media descriptions of mental illness and the mentally ill are often characterized by stigmatization. For example, in media coverage mental illnesses are often associated with crimes and violence (Ma, 2017). In consequence, patients are presented not only as peculiar and different, but also as dangerous. Thus, the media maintain misconceptions and stigma (Klin & Lemish, 2008; Srivastava et al., 2018).

Die Mischung macht's
Der Ausbruch der Corona-Pandemie stellte Eltern und Kinder weltweit vor Herausforderungen und löste Unsicherheiten aus. Eltern mussten neben dem Alltag Homeoffice, Betreuungsaufgaben und die Begleitung des Homeschoolings ihrer Kinder bewältigen. Insbesondere die Schliessung der Kindestagesstätten und Schulen sowie Ausgangsbeschränkungen veränderten die familiären Tagesabläufe, was mit einer erhöhten Mediennutzung von Heranwachsenden und Erwachsenen einherging. Der Aufsatz untersucht auf Basis der Parental-Mediation-Theorie, welche Mediationsstrategien der kindlichen Mediennutzung Eltern während des ersten Lockdowns generell und bezogen auf Informationen über das Corona-Virus einsetzten, inwiefern sie diese Strategien pandemiebedingt anpassten und welche Faktoren bestimmten, für welche Form der Medienregulation sich Eltern entschieden. Er basiert auf Leitfadeninterviews (n = 55) sowie einer Onlinebefragung von Eltern mit Kindern im Alter von drei bis 18 Jahren (n = 146). Die Befunde zeigen, dass Eltern erstens verschiedene Mediationsstrategien miteinander kombinierten, diese zweitens in der Pandemie situativ den kindlichen Bedürfnisse anpassten und drittens Kind-, Eltern- und Kontextfaktoren die Wahl der Mediationsstrategie bestimmten.The outbreak of the Corona pandemic posed challenges and resolved uncertainties for parents and children worldwide. Parents had to cope with home office, childcare responsibilities, and accompanying their children’s homeschooling in addition to everyday life. In particular, daycare and school closures and curfew restrictions altered family routines, which was accompanied by increased media use by adolescents and adults. Drawing on parental mediation theory, this paper examines the mediation strategies of childen’s media use parents used during the first lockdown in general and in relation to information about the Corona virus, the extent to which they adapted these strategies in response to the pandemic, and the factors that determined which form of media regulation parents chose. It is based on guided interviews (n = 55) and an online survey of parents with children aged three to 18 (n = 146). The findings show that parents firstly combined different mediation strategies, secondly adapted them in the pandemic depending on the situation and the child’s needs, and thirdly that child, parent, and context factors determined the choice of mediation strategy
Gender differences in gratifications from fitness app use and implications for health interventions
Previous research has shown gender differences in the motivations to be physically active, in mobile phone gratifications, and social media usage, but so far these areas have not been studied together. Based on the uses and gratification approach and self-determination theory, we aimed to identify gender-specific gratifications and determinants of fitness app usage in combination with fitness-related Facebook groups. Results of an online survey (N = 171) and of a mobile experience sampling method (N = 31) revealed that the app Runtastic was primarily used for achieving goals and to improve enjoyment for physical activity, with men and older participants sharing results with others in Facebook groups more often than women and younger participants. Conclusions regarding genderspecific targeting strategies and user-centered design and content of mHealth features are presented
