One of the environmental problems in urban areas is the pollution caused by garbage. The waste problem is caused by various factors such as population growth, living standards changes, lifestyles and behavior, as well as how the waste management system. This study aims to determine how the role of society to levy payments garbage in Samarinda. This research was descriptive; where the data is collected then compiled, described and analyzed used relative frequency analysis. The participation of the public to pay a "levy junk", which stated to pay 96.67%, for each month and the rates stated society cheap, moderate and fairly, respectively 46.08%, 21.21%, 21.04%. Base on the data , the role of the community to pay "levy junk" quite high.

Moderating Role

This study examined the link between residential mobility and interpersonal trust building. Study 1 revealed a negative association between residential mobility and trust by measuring personal residential-mobility history. Study 2 demonstrated that participants who were momentarily primed with mobility showed a lower investment than participants in the control group in a trust game. The results of Study 3 showed that need for closure moderated the link between residential mobility and trust-building intention. Specifically, lower need-for-closure people had a significantly lower trust tendency in the mobility group than in the stable group. These findings illuminate the underlying influence of need for closure in the link between residential mobility and trust.

Abstract Complaints of severe damage by whiteflies in soybean fields containing genetically engineered (GE) varieties led us to investigate the role of transgenic soybean varieties expressing resistance to some insects (Cry1Ac Bt toxin) and to herbicide (glyphosate) on the population growth and feeding behavior of Bemisia tabaci (Gennadius) MEAM1 (Hemiptera: Aleyrodidae). In the laboratory, the whiteflies reared on the GE Bt soybeans had a net reproductive rate (R0) 100% higher and intrinsic rate of population increase (rm) 15% higher than those reared on non-GE soybeans. The increased demographic performance was associated with a higher lifetime fecundity. In electrical penetration graphs, the whiteflies reared on the GE soybeans had fewer probes and spent 50% less time before reaching the phloem phase from the beginning of the first successful probe, indicating a higher risk of transmission of whitefly-borne viruses. Data from Neotropical fields showed a higher population density of B. tabaci on two soybean varieties expressing glyphosate resistance and Cry1Ac Bt toxin. These results indicate that some GE soybean varieties expressing insect and herbicide resistances can be more susceptible to whiteflies than non-GE ones or those only expressing herbicide resistance. Most likely, these differences are related to varietal features that increase host-plant susceptibility to whiteflies. Appropriate pest management may be needed to deal with whiteflies in soybean fields, especially in warm regions, and breeders may want to consider the issue when developing new soybean varieties.

This article provides an overview of the growing literature on urban-rural gaps in the developing world. I begin with recent evidence on the size of the gaps as measured by consumption, income, and wages, and argue that the gaps are real rather than just nominal. I then discuss the role of sorting more able workers into urban areas and review an array of recent evidence on outcomes from rural-urban migration. Overall, migrants do experience substantial gains on average, though smaller than suggested by the cross-sectional gaps. I conclude that future work should help further explore the frictions—in particular, information, financial, and in land markets—that hold back rural-urban migration and may help explain the persistence of urban-rural gaps.

With increased economic and population growth, air connectivity, and travel facilities, international travel of Chinese citizens has tremendously increased. Although usually in groups, there has been a growing trend among Chinese tourists toward travelling independently. These independent travellers or so-called ‘new tourists' are highly exposed to new technologies and social media and prefer to do research about possible destinations, and new travel routes and activities that package tours usually do not include. This chapter examines how social media in general and WeChat, in particular, shapes the Chinese individual travellers' travelling decisions. As will be seen, while WeChat's popularity among the Chinese outbound tourists is largely attributed to its multi-functionality, its influences on their destination visitation choice are found in multiple levels: by providing illuminating information, allowing users to integrate their payment system easily to their bank accounts in China, and providing means to obtain discounts and promotional offers in a variety of ways.
