Strategies to access and manage donations for humanitarian operations

Urrea Castaño, Gloria Cecilia ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO006.

Scarcity of funding and high competition among organizations are typical characteristics of the humanitarian setting, which create high uncertainty for humanitarian organizations (HOs) regarding their ability to access and manage the required donations for their operations. In contrast with past research, which usually considers that HOs have a passive role in the donations process, the main...

Circularly polarized reflection from the scarab beetle Chalcothea smaragdina: light scattering by a dual photonic structure

McDonald, Luke T. ; Finlayson, Ewan D. ; Wilts, Bodo D. ; Vukusic, Pete

In: Interface Focus, 2017, vol. 7, no. 4, p. 20160129

Helicoidal architectures comprising various polysaccharides, such as chitin and cellulose, have been reported in biological systems. In some cases, these architectures exhibit stunning optical properties analogous to ordered cholesteric liquid crystal phases. In this work, we characterize the circularly polarized reflectance and optical scattering from the cuticle of the beetle Chalcothea...

Art versus amusement: what do photos allow people to do?

Hua, Fan

In: Revue Tranel, 2018, vol. 68, p. 113-119

When discussing the aesthetic reaction, Vygotsky used a formula as an explanation: in a work of art, the form is always in conflict with the content, and the artist always overcomes content with form. Vygotsky unfolded the formula mostly in literature, however, he claimed that the formula can be applied to all other art forms. In this article, Vygotsky's formula is employed to photography....

Is the power of weak ties universal? A cross-cultural comparison of social interaction in Argentina and Canada

Tilston, Ottilie ; Sandstrom, Gillian

In: Revue Tranel, 2018, vol. 6811, p. 107-112

Although we interact with a wide range of people on a daily basis, the social psychological literature has primarily focused on interactions with close friends and family (i.e. strong ties). Recent research carried out on Canadian students suggests emotional benefits to interacting with acquaintances (i.e. weak social ties). The present study investigates whether this 'weak tie effect' holds in...

A design approach to team coordination

Avdiji, Hazbi ; Missonier, Stéphanie

In: Revue Tranel, 2018, vol. 68, p. 97-106

Team coordination over long time scales has been analyzed through two dominant perspectives: the contingency approach and the discursive approach. While they produced extensive theoretical contributions, these two perspectives are not well-suited to understand team coordination in changing and uncertain situations such as innovation projects. In this paper, we propose a design approach to...

Sharing emotions impacts computer-supported collaborative processes: effect of an emotion awareness tool

Avry, Sunny ; Molinary, Gaëlle

In: Revue Tranel, 2018, vol. 68, p. 85-96

There is a large consensus among researchers on the significant role of emotions in group effectiveness and performance. Emotion awareness tools (EATs) have been developed in recent years allowing members of a group to identify with their own- and their partner's emotions through a computer-mediated collaboration. In this study, we report the impact of an EAT on socio-cognitive and relational...

Intentional communication in primates

Zuberbühler, Klaus

In: Revue Tranel, 2018, vol. 68, p. 69-75

Human communication, including language, is the product of underlying intentions that are purposely expressed, epistemically monitored and flexibly interpreted. A main question in science has been about the evolutionary origins of this cognitive capacity. One way to address the problem is by studying the natural communication of animals, particularly nonhuman primates. As everything in biology,...

Sharing perception when using hands-on exhibits in science centres: the case of vocal depiction

Brandenberger, Christina ; Hottiger, Christoph

In: Revue Tranel, 2018, vol. 68, p. 59-68

There are various situations in our daily lives in which we share sensory perceptions in interaction, but research on how exactly we do this is relatively scarce and has often focused primarily on the visual and auditory channels. In this paper, we suggest an approach based on the methods of multimodal conversation analysis which also considers other perceptual fields, especially touch. By means...
