“…In [28], Sakamoto et al presented a system integrating a fictional character into existing physical games through a concept named transmedia storytelling [6,26] to increase people's awareness of pursuing more desirable lifestyles. Incorporating fictionality into micro-crowdfunding by assigning a fictional role to community members motivates them to propose and complete a micro-mission towards the target goal defined in micro-crowdfunding if a fictional story embedded as transmedia storytelling presents ideological messages that identify the micro-missions important to achieving the goal.…”

“…Physical incentives have been used to make virtual objects tangible, and ideological incentives have been used to embed ideological messages into services to increase people's intrinsic motivation. Psychological incentives become more effective when used in conjunction with ideological incentives [28]. We consider how to use these three incentives in micro-crowdfunding systems in future research.…”

“…However, as shown in [20], gamifying crowdsourcing services may not work well because game mechanics, such as points and badges, are not sufficient to encourage people to increase their target activities. Because ideological incentives are essential factors in increasing people's intrinsic motivation, as shown in [27,28], many successful games offer ideological incentives with well-designed psychological incentives that stimulate people's emotions effectively.…”

This paper introduces a new approach, named microcrowdfunding, for motivating people to participate in achieving a sustainable society. Increasing people's awareness of how they participate in maintaining the sustainability of common resources, such as public sinks, toilets, shelves, and office areas, is central to achieving a sustainable society. Micro-crowdfunding, as proposed in the paper, is a new type of community-based crowdsourcing architecture that is based on the crowdfunding concept and uses the local currency idea as a tool for encouraging people who live in urban environments to increase their awareness of how important it is to sustain small, common resources through their minimum efforts. Because our approach is lightweight and uses a mobile phone, people can participate in micro-crowdfunding activities with little effort anytime and anywhere.We present the basic concept of micro-crowdfunding and a prototype system. We also describe our experimental results, which show how economic and social factors are effective in facilitating micro-crowdfunding. Our results show that microcrowdfunding increases the awareness about social sustainability, and we believe that micro-crowdfunding makes it possible to motivate people for achieving a sustainable society.

“…The details of our Ga-FIB-TOF-SIMS apparatus, which had a minimum lateral resolution of 40 nm, have already been reported. [10] The acceleration voltage of the Ga primary was 30 kV, and a 200 ns pulse width at a frequency of 15 kHz was applied.…”

Ga‐focused ion beam time‐of‐flight secondary ion mass spectrometry (FIB‐TOF‐SIMS) analysis was performed to investigate the grain boundary segregation/precipitation of boron in steel. To overcome the low secondary ion yield from the primary Ga+ source and the sensitivity using a high‐resolution Ga‐FIB source, a low energy oxygen ion beam was used prior to the Ga‐FIB‐TOF‐SIMS analysis. As a result, it was found that Ga‐FIB‐TOF‐SIMS is a very powerful tool for mapping boron segregation and/or precipitation in steel with a spatial resolution of ~200 nm. In addition, the results were strongly dependent on the surface composition. Copyright © 2014 John Wiley & Sons, Ltd.

“…Bite performance, for example, has been studied in a wide range of vertebrates through estimations based on cranial morphology and biomechanical models, or by direct in vivo measurements of bite force. These studies span a wide array of taxa including alligators (Erickson, Lappin & Vliet, 2003), turtles (Herrel, Petrochic & Draud, 2017), carnivores (Christiansen & Wroe, 2007;Sakamoto, Lloyd & Benton, 2010;Law, Young & Mehta, 2016), bats (Nogueira, Peracchi & Monteiro, 2009;Santana, Dumont & Davis, 2010), various other mammals (Thomason, 1991;Freeman & Lemen, 2008) and birds (van der Meij & Bout, 2004;Herrel et al, 2005a,b). The importance of bite performance in feeding is well-illustrated by Darwin's finches of the Galapagos Islands, where individuals with large beaks, which have high bite forces (Herrel et al, 2005b), are selected during drought episodes during which only large seeds are available (Boag & Grant, 1981).…”

Drivers of in vivo bite performance in wild brown mouse lemurs and a comparison with the grey mouse lemur

et al. 2018

Physical performance is crucial for animal survival and fitness. In this context, greater bite forces can provide advantages and may allow an individual to gain access to reproductive partners and/or different food resources. Here, we explored the determinants of bite force in a wild population of the brown mouse lemur (Microcebus rufus). Our objectives were to elucidate (1) if sex, head width, heart rate (as an indicator of overall physical fitness) and body condition drive variation in bite force in this population of wild mouse lemurs; and (2) the relative importance of the ecological niche in determining bite force by comparing results from this wild population with previously published results on bite force, body mass and head width from a laboratory colony of the grey mouse lemur (Microcebus murinus). We captured 32 wild brown mouse lemurs at night in the Ranomafana National Park in Madagascar during the beginning of the rainy season from 1st to 31st October 2016. We measured bite force, heart rate, body mass and head width of all individuals, and assigned sex and body condition (estimated as the unstandardized residual of a regression of body mass against head size). Although maximum bite force was positively correlated with body mass, it was not correlated with body condition. Residual bite force was highly correlated with residual head width and heart rate. The mean bite force of wild brown mouse lemurs was much lower than that of grey mouse lemurs in captivity, but showed similar relationships to head dimension and body mass. Even when corrected by body condition, grey mouse lemurs bit significantly harder than brown mouse lemurs. The difference in bite force between species could be explained by differences in head size and niche divergence with brown mouse lemurs eating mostly soft fruits and grey mouse lemurs eating more hard insects.
