The few panel data tests for predictability of returns that exist are based on the prerequisite that both the number of time series observations, $T$, and the number of cross-section units, $N$, are large. As a result, these tests are impossible for stock markets where lengthy time series data are scarce. In response to this, the current paper develops a new test for predictability in panels where
This paper examines how social relations and norms contribute to the emergence of generalized trust in economic action. Our core proposition is that the more positive the local social exchange relationship, the greater an actor’s propensity to place trust in strangers. Our research design integrates behavioral measures elicited by incentivized experimental trust games with survey data using a rand
SeaWiFS satellite data were employed to demonstrate how the biological conditions in marine and coastal waters may be characterized using the concentration of chlorophyll-alpha (chl-alpha) and dissolved organic carbon (DOC) as the leading parameters. In marine waters the standard algorithms from the SeaWiFS Data Analysis System (SeaDAS) package were used to derive the concentrations, whereas in co
Recent work on heritage and social media has highlighted how social media offer new possibilities for citizens to share memories, identities, local culture and heritage, and thus constitute a more participatory and democratic platform (Giaccardi 2012). Social media encourage and enable new forms of engagement and interpretations of the heritage through user-generated content, personal reflections,
Conodont faunas from the Eoplacognathus pseudoplanus Zone in five main areas of Middle Ordovician rocks in Sweden are described and discussed and compared with faunas of comparable age from neighbouring areas. The investigation is based on 118 samples which together yielded 175 114 conodont elements. The Swedish conodont faunas are intermediate between shallower-water faunas from the eastern part
Economic institutions enabling trust and cooperation rest on multiplex networks and norms of reciprocity. A key feature of economic institutions is that they facilitate commercial transactions by reducing uncertainty and risk in markets. When trust and trustworthiness stem from confidence in community sanctions of norms, principal and agent relations are enforceable without resorting to legal rule
Cationic 1,3,5‑triaza‑phosphaadamantane (PTA) quinoline ruthenium(II) and iridium(III) complexes were successfully synthesized and characterized using standard spectroscopic and analytical techniques. The complexes were evaluated for their in vitro antiplasmodial activities against the chloroquine-sensitive (CQS) NF54 and chloroquine-resistant (CQR) K1 strains of the Plasmodium falciparum species
Smart and Sustainable Cities? Pipedreams, Practicalities and Possibilities provides one of the first examinations of how smart cities relate to environmental and social issues. It addresses the gap between the ambitious visions of smart cities and the actual practices on the ground by focusing on the social and environmental dimensions of real smart city initiatives as well as the possibilities th
This paper argues for the importance of using the regional innovation systems (RIS) approach as both an analytical framework and a policy tool for generating economic development in developing countries. The paper reconceptualizes the RIS-model to the context of developing countries. RIS is normally based on endogenous growth models; however, in this paper we extend it to rely on external capital,
Objective: Needle acupuncture in small children has gained some acceptance in Western medicine. It is controversial, as infants and toddlers are unable to consent to treatment. We aimed to assess its efficacy for treating infantile colic. Design: A systematic review and a blinding-test validation based on individual patient data from randomised controlled trials. Primary end-points were crying tim
Where does generalized trust—that is, the inclination to place trust in strangers—come from? Our claim is that in economic action, sources of generalized trust may not differ much from the sources of personalized trust. Contrary to a common assumption of a sharp distinction between personalized and generalized trust, we assert a likely spillover effect from relational exchange to a person’s expect
This project is cooperated with IKEA, under their “Future Home ” project. “Resource sharing“ is one of the subparts. The main idea is to encourage people to share resources and time to lower the cost and to reduce carbon footprint. The focus is to motivate residents to have more social interactions with their neighbours, which is the beginning of sharing. The strategy is to learn from traditional
