Analyzing cultural tourism promotion on Instagram : a cross-cultural perspective

Mele, Emanuele ; Kerkhof, Peter ; Cantoni, Lorenzo

In: Journal of travel & tourism marketing, 2021, vol. 38, no. 3, p. 326-340

A lack of cross-cultural research has been identified regarding cultural tourism promotion on social media. Using the dimensions of Collectivism-Individualism, Power Distance, and High-Context vs. Low-Context communication, we content analyze cultural value differences in Instagram posts promoting cultural tourism – published by the national tourism organizations of Chile, Portugal, USA, and...

Knowledge of results during vertical jump testing: an effective method to increase the performance but not the consistency of vertical jumps

García-Ramos, Amador ; Janicijevic, Danica ; Cobo-Font, Juande ; Marcos-Frutos, Daniel ; Fernandes, John F. T. ; Taube, Wolfgang ; Pérez-Castilla, Alejandro

In: Sports Biomechanics, 2020, vol. 0, no. 0, p. 1–13

This study aimed to determine whether the provision of jump height feedback (knowledge of result; KR) can increase the performance and the consistency of output variables. In a randomised order, sixteen participants performed six squat or countermovement jumps (three from a 90º knee angle and three from a self-preferred knee angle) with or without KR over four sessions. The provision of KR...

Glacier runoff variations since 1955 in the Maipo River basin, in the semiarid Andes of central Chile

Ayala, Álvaro ; Farías-Barahona, David ; Huss, Matthias ; Pellicciotti, Francesca ; McPhee, James ; Farinotti, Daniel

In: The Cryosphere, 2020, vol. 14, no. 6, p. 2005–2027

As glaciers adjust their size in response to climate variations, long-term changes in meltwater production can be expected, affecting the local availability of water resources. We investigate glacier runoff in the period 1955–2016 in the Maipo River basin (4843 km2, 33.0–34.3∘ S, 69.8–70.5∘ W), in the semiarid Andes of Chile. The basin contains more than 800 glaciers, which...

Gender-based price discrimination in the annuity market : evidence from Chile

Bello, Piera

This paper studies gender-based price discrimination in the annuity market. The dataset consists of transaction-level data on the universe of individuals accessing the Chilean annuity market in the 2004-2017 period. It exploits the fact that, in Chile, individuals can access the annuity market through three different channels: an independent financial advisor, a sales agent at a company, or...

A conceptual framework for range-expanding species that track human-induced environmental change

Essl, Franz ; Dullinger, Stefan ; Genovesi, Piero ; Hulme, Philip E ; Jeschke, Jonathan M ; Katsanevakis, Stelios ; Kühn, Ingolf ; Lenzner, Bernd ; Pauchard, Aníbal ; Pyšek, Petr ; Rabitsch, Wolfgang ; Richardson, David M ; Seebens, Hanno ; van Kleunen, Mark ; van der Putten, Wim H ; Vilà, Montserrat ; Bacher, Sven

In: BioScience, 2019, vol. 69, no. 11, p. 908–919

For many species, human-induced environmental changes are important indirect drivers of range expansion into new regions. We argue that it is important to distinguish the range dynamics of such species from those that occur without, or with less clear, involvement of human-induced environmental changes. We elucidate the salient features of the rapid increase in the number of species whose...

On the bend number of circular-arc graphs as edge intersection graphs of paths on a grid

Alcón, Liliana ; Bonomo, Flavia ; Durán, Guillermo ; Gutierrez, Marisa ; Mazzoleni, María Pía ; Ries, Bernard ; Valencia-Pabon, Mario

In: Discrete applied mathematics, 2018, vol. 234, p. 12-21

Golumbic, Lipshteyn and Stern [12] proved that every graph can be represented as the edge intersection graph of paths on a grid (EPG graph), i.e., one can associate with each vertex of the graph a nontrivial path on a rectangular grid such that two vertices are adjacent if and only if the corresponding paths share at least one edge of the grid. For a nonnegative integer k, Bk-EPG graphs are...

The protein disulfide isomerase ERp57 regulates the steady-state levels of the prion protein

Torres, Mauricio ; Medinas,Danilo B. ; Matamala, José Manuel ; Woehlbier, Ute ; Cornejo, Víctor Hugo ; Solda, Tatiana ; Andreu, Catherine ; Rozas, Pablo ; Matus, Soledad ; Muñoz, Natalia ; Vergara, Carmen ; Cartier, Luis ; Soto, Claudio ; Molinari, Maurizio ; Hetz, Claudio

In: The journal of biological chemistry, 2015, vol. 290, no. 39, p. 23631-23645

Although the accumulation of a misfolded and protease-resistant form of the prion protein (PrP) is a key event in Prion pathogenesis, the cellular factors involved in its folding and quality control are poorly understood. PrP is a glycosylated and disulfide-bonded protein synthesized at the endoplasmic reticulum (ER). The ER foldase ERp57 (also known as Grp58) is highly expressed in the brain...

Life-history evolution and the polyphenic regulation of somatic maintenance and survival

Flatt, Thomas ; Amdam, Gro V. ; Kirkwood, Thomas B. L. ; Omholt, Stig W.

In: The Quarterly Review of Biology, 2013, vol. 88, no. 3, p. 185–218

Here we discuss life-history evolution from the perspective of adaptive phenotypic plasticity, with a focus on polyphenisms for somatic maintenance and survival. Polyphenisms are adaptive discrete alternative phenotypes that develop in response to changes in the environment. We suggest that dauer larval diapause and its associated adult phenotypes in the nematode (Caenorhabditis elegans),...
