Abstract Philosophers and scientists propose the idea that plants are cognitive, which has been met with criticisms. These criticisms focus on fact do not possess properties traditionally associated cognition. By contrast, several proponents introduce novel ways to conceptualize How should we make sense of this debate? In paper, I argue plant cognition debate is about whether meet a set well-de...
the present paper investigates how far ideologies can be tease out in discourse by examining the employed schemata by two ideologically opposed news media, the bbc and press tv, to report syria crisis during a period of nine months in 2011. by assuming that news is not a valuefree construction of facts and drawing on micro structural approach of schema theory, for the first time in discours...
Over a hundred years ago Galton reported on the uncanny accuracy of the median estimate of the weight of an ox, as judged by spectators at a country fair [1]. Since then, the notion that the ‘wisdom of the crowd’ is superior to any individual has itself become a piece of crowd wisdom, raising expectations that web-based opinion aggregation might replace expert judgment as a source of policy gui...
Abstract. In this paper, we consider vibrating system of Timoshenko type in one-dimensional bounded domain with complementary past history and frictional damping controls acting only in the equation for the rotation angle. We show that the dissipation given by this complementary controls is strong enough to guarantee the stability of the system in case of the same wave propagation speeds as wel...
To effectively improve the tire grounding behaviors of wheelchair robots, an analytical method is proposed to analyze and optimize the tire grounding safety. Firstly, taking the cushion and tires as the vibration isolation elements with stiffness and damping, the vertical vibration model of the human-wheelchair robot is established. Then, taking the random excitation as the typical input, the f...
The damping ratio of chassis suspension is a key parameter for damping matching of in-wheel motor vehicles (IWMVs). Because the motor is attached to the driving wheel, the initial design method of the damping ratio for traditional cars is not entirely suitable for IWMVs. This paper proposes an innovative initial design method of the damping ratio for IWMVs. Firstly, a traveling vibration model ...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
It is well known that people conform to normative information about other people's current attitudes and behaviors. Do they also conform to dynamic norms-information about how other people's behavior is changing over time? We investigated this question in three online and two field experiments. Experiments 1 through 4 examined high levels of meat consumption, a normative and salient behavior th...
