The Co-Evolution of Public Relations and Journalism : a First Contribution to its Systematic Review

Schönhagen, Philomen ; Meissner, Mike

In: The Proceedings of the International History of Public Relations Conference, 2015, p. 232-248

The relationship between public relations (PR) and journalism is mostly conceived of as between “interdependent systems” (Grossenbacher, 1986: 730). In this context, Löffelholz mentions evidence of a “co-evolutionary development of journalism and public relations” that “has not to date been systematically pursued” (Löffelholz, 2004: 472; emphasis author's own). To do so would...

Shining a light on species delimitation in the tree genus Engelhardia Leschenault ex Blume (Juglandaceae)

Zhang, Can-Yu ; Low, Shook Ling ; Song, Yi-Gang ; Nuraina ; Kozlowski, Gregor ; Do, Truong Van ; Li, Lang ; Zhou, Shi-Shun ; Tan, Yun-Hong ; Cao, Guan-Long ; Zhou, Zhuo ; Meng, Hong-Hu ; Li, Jie

In: Molecular Phylogenetics and Evolution, 2020, vol. 152, p. 106918

Enhanced efficacy in species delimitation is critically important in biology given the pending biodiversity crisis under global warming and anthropogenic activity. In particular, delineation of traditional classifications in view of the complexity of species requires an integrative approach to effectively define species boundaries, and this is a major focus of systematic biology. Here, we...

A taxonomic revision of geoemydid turtles from Siwalik-age of India and Pakistan

Garbin, Rafaella C. ; Bandyopadhyay, Saswati ; Joyce, Walter G.

In: European Journal of Taxonomy, 2020, no. 652, p. -

Neogene (Siwalik-aged) deposits from India and Pakistan have yielded many vertebrate fossils, of which most were named during the 19th century, including numerous geoemydid turtles. In contrast to many other faunal components from the Siwaliks, geoemydids have not undergone taxonomic revision for more than a century and most fossils have therefore been believed to correspond to recent taxa....

Biocontrol of invasive weeds under climate change: progress, challenges and management implications

Sun, Yan ; Ding, Jianqing ; Siemann, Evan ; Keller, Stephen R.

In: Current Opinion in Insect Science, 2020, vol. 38, p. 72–78

Climate change is predicted to increase the frequency and impact of plant invasions, creating a need for new control strategies as part of mitigation planning. The complex interactions between invasive plants and biocontrol agents have created distinct policy and management challenges, including the effectiveness and risk assessment of biocontrol under different climate change scenarios. In...

Ranking game on networks: The evolution of hierarchical society

Zhang, Xin-Jie ; Tanga, Yong ; Xiong, Jason ; Wang, Wei-Jia ; Zhang, Yi-Cheng

In: Physica A: Statistical Mechanics and its Applications, 2020, vol. 540, p. 123140

Interacting with each other, individuals in a population form various social network topologies. Models of evolutionary games on networks provide insight into how the collective behaviors of structured populations are influenced by individual decision making and network topologies. In a hierarchical society, many social resources are allocated according to certain social rankings, such as...

Recent glacier and lake changes in High Mountain Asia and their relation to precipitation changes

Treichler, Désirée ; Kääb, Andreas ; Salzmann, Nadine ; Xu, Chong-Yu

In: The Cryosphere, 2019, vol. 13, no. 11, p. 2977–3005

We present an updated, spatially resolved estimate of 2003–2008 glacier surface elevation changes for the entire region of High Mountain Asia (HMA) from ICESat laser altimetry data. The results reveal a diverse pattern that is caused by spatially greatly varying glacier sensitivity, in particular to precipitation availability and changes. We introduce a spatially resolved zonation where...
