A New Spatial Shift‐Share Decomposition: An Application to Tourism Competitiveness in Italian Regions
2020
The paper proposes a new version of spatial shift-share decomposition to improve on the various approaches to conventional shift-share analysis found in the literature. The novelty of our proposal is that it enables researchers to assess spatial competitiveness effects controlling for the influence of industrial specialization at both regional and neighborhood level. This new version is applied to inbound tourism in Italian regions and enables us to identify the best and worst performers. Our empirical results identify favorable scenarios in some areas of the country, such as Sardinia as well as regional advantage in a sizeable number of well-known destinations.
Improving the Effect of Transcranial Alternating Current Stimulation (tACS): A Systematic Review
2021
With the development of electrical stimulation technology, traditional transcranial alternating current stimulation (tACS) technology has been found to have the drawback of not targeting a specific area accurately. Studies have shown that optimizing the number and position of electrodes during electrical stimulation has a very good effect on enhancing brain stimulation accuracy. At present, an increasing number of laboratories have begun to optimize tACS. However, there has been no study summarizing the optimization methods of tACS. Determining whether different optimization methods are effective and the optimization approach could provide information that could guide future tACS research. …
Analiza przestrzennego zróżnicowania zmian w potencjale infrastruktury transportowej w Polsce
2015
Wiele zachodzących zjawisk, ich rozwój czy kierunki zmian, uzależnionych jest od przestrzennych interakcji pomiędzy sąsiadującymi regionami. Model przestrzennej analizy shift-share (SSSA) został wprowadzony do badań przez S. Nazarę i G.J.D. Hewingsa. Przedstawia on przestrzennie zmodyfikowane stopy wzrostu (tempa zmian) poszczególnych wariantów zjawiska przez uwzględnienie temp wzrostu zjawiska w obszarach sąsiadujących. Celem artykułu jest analiza zmian struktury infrastruktury transportowej w województwach Polski w latach 2004 oraz 2014, według rodzajów infrastruktury transportowej z zastosowaniem przestrzennej dynamicznej metody przesunięć udziałów. W opracowaniu dokonano oceny tempa wzr…
Working hours – tracking the current and future trends
2021
It is important to track the trends of future working hours, since working hours have strong associations to everyday life and work-life interaction, but also to health. In this paper we aim to track the current and future trends in working hours. We discuss the trends through the key dimensions of working hours: the length, timing, tempo and autonomy. We also consider the role of current trends of spatial changes of work. Changes in working time patterns are fostered by several driving factors: globalization and business restructuring challenging the current work organizations, new information technologies, demographic and climate change and the current and future pandemics. The past and c…
The impact of life stage and pigment source on the evolution of novel warning signal traits
2021
Our understanding of how novel warning color traits evolve in natural populations is largely based on studies of reproductive stages and organisms with endogenously produced pigmentation. In these systems, genetic drift is often required for novel alleles to overcome strong purifying selection stemming from frequency-dependent predation and positive assortative mating. Here, we integrate data from field surveys, predation experiments, population genomics, and phenotypic correlations to explain the origin and maintenance of geographic variation in a diet-based larval pigmentation trait in the redheaded pine sawfly (Neodiprion lecontei), a pine-feeding hymenopteran. Although our experiments c…
