Combining pheromone trapping and genetic analyses can be useful whentrying to resolve complexes of closely related insect taxa that are difficult to distinguishbased on morphological characters. Nearctic and Palearctic populations of the spruceseed moth, Cydia strobilella L., have been considered taxonomically synonymoussince 1983, but more recent work revealing distinct sex pheromones for Canadia

Around the world, the treatment of food waste is a major administrative and environmental problem throughout the food supply chain.

Palaeoceanographic changes over the last 6800 years are documented in a diatom record from core MD05-2908 from the southern Okinawa Trough. Changes in diatom components are used to reflect variations in the strength of the Kuroshio Current and the influence of coastal waters, and these changes are compared with records of the East Asian summer monsoon, which exerts an important influence on region

Highly oxygenated multifunctional compounds (HOMs) play a key role in new particle formation (NPF), but their quantitative roles in different environments of the globe have not been well studied yet. Frequent NPF events were observed at two flagship stations under different environmental conditions, i.e. a remote boreal forest site (SMEAR II) in Finland and a suburban site (SORPES) in polluted eas

This thesis consists of three self-contained papers. The first paper, Sorting on Unobserved Skills into New Firms, adds to the literature on worker characteristics and post-entry firm performance by putting the unobserved quality of workers in the center of analysis. Although human capital features prominently in theoretical work on the post-entry performance of new firms, empirical analysis has

Corporate Social Responsibility (CSR) is a fairly new concept that acknowledges the social and environmental responsibility of Multinational Corporations (MNCs). This thesis sets out to investigate the incentives for Multinational Corporations to engage in CSR and, if they choose to do so, what effects such an engagement has on development in the host country of investments.

In a working world faced with technological innovation, rampant viruses, environmental and climate change, and a volatile global political situation, agricultural workers face the continuing dual human rights dilemma of occupational health and safety and access to a healthy environment. More than a third of the world's working population is engaged in agriculture, which plays a vital role in d

This thesis investigates the volatility spillover and contagion effects to the frontier markets from the developed markets and emerging markets and tries to identify if there exists any potential volatility effect which may have impact on the investment decision of these markets. In view of the growing globalization, financial markets become increasingly interdependent and the chances for the vola

Inspired by cultural geographer David Crouch’s description of heritage as a journey,3 this paper looks at how the narrator’s physical and mental voyage towards the old capital of her childhood incorporates multiple spatiotemporal layers of urban cultural heritage in order to reach a deeper understanding of the living historical city she calls home.
