Abstract Lesser kestrels Falco naumanni are migratory central-place foragers that breed in dynamic arable landscapes. After arriving from migration, kestrels have no knowledge of the distribution of crops, and consequently prey, around their colony. The energy demand of pairs increases as breeding season progresses, but at the same time prey abundance, and their knowledge on prey distribution, also increases. Wind can have a strong influence on flight cost and kestrels should try to reduce energy expenditure when possible. When prey abundance is low, kestrels have little knowledge of prey distribution, and pairs have no chicks, they could reduce foraging flight cost by leaving the colony with tailwinds. When prey is abundant, knowledge on prey distribution has increased, and chick demand is high, kestrels should fly to the most favorable foraging patches. We analyzed foraging trips directions in a lesser kestrel colony along the breeding season and in relation to wind speed and direction. We recorded 664 foraging trips from 19 individuals using GPS-dataloggers. We found that outward flights direction changed from uniform to a concentrated distribution along the season, as prey abundance and individual experience increased. We also found a temporal trend in the angular difference between outward flights and wind directions, with low values early in the season and then increasing as expected, but again low values at the end, contrary to expectation. Results suggest changes in kestrels foraging strategy along the season in relation to wind. Kestrels depart more with tailwinds in exploratory flights early in the season, while there is a spurious coincidence in direction to preferred foraging patches and dominant wind direction at the end.

ABSTRACTThis paper addresses the issue of corporate sustainability. It examines why achieving sustainability is becoming an increasingly vital issue for society and organisations, defines sustainability and then outlines a set of phases through which organisations can move to achieve increasing levels of sustainability. Case studies are presented of organisations at various phases indicating the benefits, for the organisation and its stakeholders, which can be made at each phase. Finally the paper argues that there is a marked contrast between the two competing philosophies of neo-conservatism (economic rationalism) and the emerging philosophy of sustainability. Management schools have been strongly influenced by economic rationalism, which underpins the traditional orthodoxies presented in such schools. Sustainability represents an urgent challenge for management schools to rethink these traditional orthodoxies and give sustainability a central place in the curriculum.

Critical Interest

Our understanding of Anglophone modernism has been transformed by recent critical interest in translation. The central place of translation in the circulation of aesthetic and political ideas in the early twentieth century has been underlined, for example, as well as translation’s place in the creative and poetic dynamics of key modernist texts. This volume of Katherine Mansfield Studies offers a timely assessment of Mansfield’s place in such exchanges. As a reviewer, she developed a specific interest in literatures in translation, as well as showing a keen awareness of the translator’s presence in the text. Throughout her life, Mansfield engaged with new literary texts through translation, either translating proficiently herself, or working alongside a co-translator to explore the semantic and stylistic challenges of partially known languages. The metaphorical resonances of translating, transition and marginality also remain key features of her writing throughout her life. Meanwhile, her enduring popularity abroad is ensured by translations of her works, all of which reveal sociological and even ideological agendas of their own, an inevitable reflection of individual translators’ readings of her works, and the literary traditions of the new country and language of reception. The contributions to this volume refine and extend our appreciation of her specifically trans-linguistic and trans-literary lives. They illuminate the specific and more general influences of translation on Mansfield’s evolving technique and, jointly, they reveal the importance of translation on her literary language, as well as for her own particular brand of modernism.

This book explores the meaning of “soul” in sacred and profane incarnations, from its biblical origins to its central place in the rich traditions of black and Latin history. Surveying the work of writers, artists, poets, musicians, philosophers, and theologians, the book shows how their understandings of the “soul” revolve around narratives of justice, liberation, and spiritual redemption. The book contends that biblical traditions and hip-hop emerged out of experiences of dispossession and oppression. Whether born in the ghettos of America or of the Roman Empire, hip-hop and Christianity have endured by giving voice to the persecuted. This book offers a view of soul in living color, as a breathing, suffering, dreaming thing.

The article is devoted to the content of the concept of "environmental innovation" in the system of socio-economic relations of the green economy. The genesis of the origin of the category "green economy" and the specifics of its functional content are clarified. It is stated that in contrast to international legal documents in the legislation of Ukraine there is no clear and systematic separation of the green economy as an important segment of the national economy. The article emphasizes the idea that the central place in the green economy should be occupied by two system-forming categories. The first is ecological management, which can be implemented in both commercial and non-commercial forms. The second is environmental innovation, as a source of the green economy gaining the same level of profitability as the traditional economy, and over time, its significant growth. Various definitions of "environmental innovation" are considered, as there is no single definition today. The article emphasizes the prospects of environmental innovations and the green economy in general, emphasizes their profitability. It is believed that caring for the ecosystem in which we live is not only a modern trend, but also a guarantee of stability of the entire biosphere. These aspects pose a large number of challenges to the environmental and economic legislation of Ukraine, both in terms of institutionalization of these categories, and in terms of providing them with effective implementation mechanisms. An attempt has been made to identify in which legislative acts these issues could be resolved. It was emphasized that the legislator does not provide any benefits for the introduction of environmental innovations and environmental management. It is proposed to introduce certain incentives for businesses that use environmental technologies or attract other environmental innovations, in the form of tax benefits.

History Of

The study is an investigation of the origins of psychophysics and experimentalpsychology. According to historians of psychology. FrancisBacon had the most crucial influence in the history of the experimentalmethod, because he emphasized the importance of induction, skepticism,quantification, and observation. The present study, however,attempts to show that Ibn al-Haytham laid the foundations of the aboveaspects of the experimental method. Furthermore, a number of historiansof psychology believe that Fechner was the founder of psychophysicswith his application “Filements of Psychophysics” in 1860.This study shows that in the eleventh century, Ibn al-Haytham made anoriginal contribution to the study of vision, wherein his psychophysicsborrowed its structure from physics and its spirit from psychology.Several aspects of visual perception were investigated by him, includingsensation (which occupies a central place in psychophysics), variationsin sensitivity, perception of colors. sensation of touch, perceptionof darkness, the psychological explanation of moon illusion, and binocularvision. This study presents five experiments by Ibn al-Haythamregarding the errors of vision, which is called in contemporary psychology“visual illusion.” These experiments have been applied andverified in Bahrain from both the physical and psychological perspectives.Finally, the study concludes that Ibn al-Haytham deserves the title“founder” of psychophysics as wellp the “founder” of experimentalpsychology. In this respect. Kitab ul-Manazir by Ibn al-Haytham.which appeared in the fmt half of the eleventh century, and not the“Elements of Psychophysics” by Fechner. which was published in thenineteenth century, marks the official “founding” of psychology,because it provides not only new concepts and theories but new methodsof measurement in psychology.

The Impact

The article defines the content of welfare as a measure of socially oriented efficiency of economic growth, which reflects the appropriate level of providing the population with material and spiritual goods with the formation of favourable conditions for human development and capitalization of human potential in a competitive mobile space. The modern theory of welfare testifies to the deepening of scientific discussions on the transformation of economic welfare into mobile and inclusive, as well as the opposition of competitive and social protection welfare policy. Another milestone in the evolution of welfare theory is the individualization of its provision. Conditions of competition and mobility increase the importance of households in providing their well-being with further reflection on the processes of economic growth of the community, region, and state. This gives grounds to actualize the issues of household welfare research and strengthening economic growth based on behavioural economics. The needs, interests, motives, and incentives determine the economic behaviour of households. At higher levels, it defines an economic culture that is closely linked to the national mentality. In this regard, the main models of economic and social behaviour of households – socialization, adaptation, integration, values, regulation, and the definition of financial development strategies are outlined. Theoretical approaches to the explanation of economic behaviour are generalized, namely religious-ethical, psychological, substantive theories, theories of motivations and acquired needs, process theories, theories of justice, and others. Based on the ideas of foreign scientists, the main determinants of the economic policy of households are proposed. Political, stabilizing, and economic determinants are distinguished in the group of general determinants. In the group of determinants directly related to households, the financial, demographic, cultural, social, empirical, and psychological are suggested. The author’s emphasis is placed on the importance of the impact of financial determinants of the households’ economic behaviour, the central place among which is occupied by savings.
