The aim of this paper is to compare the demographic potential of given Italian and Polish regions. The analysis shows that the demographic situation in Poland, unlike in Italy, is not directly related to the level of development of some regions and their geographical location. In Italy, the unfavorable demographic situation is typical of most of the less-developed southern regions, whereas in Poland it oc­curs in voivodships with different economic potential, situated in different parts of the country. This is probably the result of the current polycentric development of Poland, characteristic of a centralized economy, and the polar development in Italy. Certain demographic similarities, but of different levels, related to the dynamics of the population, the level of fertility, and net migration are observable in the macro-regions of Mezzogiorno and Eastern Poland.

Abstract The Republic of Macedonia covers an area of 25,713 km² and according to data from the census conducted in 2002, it has a population of 2,022,547 inhabitants. In the past, the Republic of Macedonia was characterized by some significant demographic changes, including a decline in the average annual rate of population increase. The enhanced immigration movements and sudden decline in the rates of natural population increase have led to changes in distribution of the population and to a spatial differentiation in the population. The long period of transition in the country has been reflected in the spatial development of the country and its demographic processes and to relocation of the population. The different natural-geographical characteristics, unequal regional development potentials, unequal economic development, and demographic characteristics have led to changes in the demographic situation of certain regions. The regions that continually lose part of its population clearly differ from these regions that are characterized by an increased population which is leading to a greater concentration of people in certain location. Further decades with a declining birth rate, followed by a change in the values of population increase, together with migration movements, particularly from the rural and less developed economic regions, has resulted in a decline in the population. The different zones of depopulation and concentration in a simple way express the complex relationships in the population composition.

Petioles are not usually thought of as a habitat for wood-boring insects. The large, woody leaf petioles of Neotropical Cecropia trees, however, have a diverse coleopterous fauna: 36 beetle species in three subfamilies of Cerambycidae and Curculionidae were recorded from Cecropia leafstalks in Costa Rica. A high percentage of the petioles were colonized by beetles in many patches, though fewer were colonized in sun-exposed sites. Community composition was dependent on forest type, petiole moisture and geographical location, but not on the species of Cecropia. Species of Scolytinae were most abundant though species of Zygopinae and Lamiinae were found regularly. The host-specific scolytine genus Scolytodes dominated in most localities, although species of Hypothenemus, Coccotrypes and Xylosandrus morigerus occurred frequently. Sympatric species of Scolytodes clearly used different parts of the petioles. Brood sizes of scolytine beetles were extremely low, ranging from two to ten offspring on average. However, mortality due to parasitoid wasps or predators was low, and since fresh leaves fall close to the previously fallen ones, mortality due to dispersal may also be low. Thus, large beetle populations can exist despite extremely low brood sizes.

Background. The keratorefractive surgeries (KRS) are one of the most common ocular surgeries. One of the dangerous complications of these surgeries is infectious keratitis (IK), which is the second cause of blindness after cataract surgery. The purpose of this study was to estimate the prevalence of IK after KRS in different parts of the world. Methods. In order to obtain relevant studies, all national and international databases including IranMedex, SID, Magiran, IranDoc, Medlib, ScienceDirect, PubMed, Scopus, Cochrane, Embase, Web of Science, and Google Scholar were searched using standard keywords. Results. IK prevalence after KRS was 0.000496% (0.000145% for the left eye and 0.000149% for the right eye). IK prevalence after KRS in the United States, Europe, and Asia was 0.000667%, 0.000473%, and 0.000045%, respectively, in all of which the common microorganisms were Staphylococci. Meta-regression showed no significant association between IK after KRS and either sample size or publication year of the studies. IK prevalence after KRS in the right eye was more than that in the left one. Also, the probability of IK incidence after LASIK surgery was more than PRK and LASEK. In the evaluation of continents, IK after KRS in the United States was more frequent compared with Europe and Asia. Conclusions. This study provided data as to the overall prevalence of IK following KRS and its variations according to the types of eye, surgery, pathogenic microorganism, and geographical location.

Algal samples from different parts of the frond of Laminaria digitata (young, adult and aged tissues) and from macroscopic fragments naturally separated from the thallus were collected on the Atlantic coast of France (Brittany) during winter and spring. Bacterial communities associated with the different levels were compared, and the ATP content was determined and used as an indicator of the physiological state of the tissues. It is higher in young tissue (55 nmol/g of fresh kelp) than in fragments (9 nmol/g of fresh kelp), showing a decrease in the number of metabolically active cells. If total bacterial density values are relatively close on the different parts of the kelp (average, 2.9 × 107 bacteria/cm2), culturable microflora increased from young tissue (minimum, 15 cfu/cm2) to fragments (average, 3.6 × 107 bacteria/cm2). Characterization of strains showed an increase of metabolic activity together with a diversification in the culturable fraction with the age of algal tissues.Key words: epiphytic bacteria, kelp, Laminaria digitata.

This paper outlines the reported discrepancies between the aims of the welfare services in Iceland and the experiences of parents raising young children with intellectual disabilities. Prevailing views on disability and service delivery were also considered. A multi case study design was employed to reflect the situation in different parts of the country. Families of eight children with intellectual disabilities and professionals in three different municipalities formed the cases. The findings reveal a high convergence between the three cases with variations based on individual experiences rather than geographical location. Overall, parents praised the preschools but experienced support services often as fragmented and uncompromising. Particular components of the services were consistently regarded as hard to reach and not in accordance with the needs of the family. Cultural-historical activity theory is introduced as a beneficial framework for further study and system improvement.

Abstract In the years 2001-2003, a study on thrips (Thysanoptera) was conducted in Lublin (south-eastern Poland). The aim of the research was to determine the species composition of the insects on selected plants from the Asteraceae family collected at sights of varying anthropopressures in Lublin. Fifteen designated sites, classified as semi-natural and anthropogenic, were located in different parts of the city. As a result of the study, the occurrence of 36 thrips species was recorded. The species dominating in the whole material were: Thrips physapus, Thrips trehernei, Thrips validus and Frankliniella intonsa. The greatest thrips species variety was characteristic of the following plant species: Hieracium umbellatum, Matricaria perforata, Taraxacum officinale, Erigeron strigosus. The research conducted shows that urban environment is quite rich in terms of thrips species diversity. The number of species caught indicates their tolerance to moderately adverse conditions in the city. The most important factor affecting the number of collected species is plant diversity. The sites of different levels of athropopressure varied both in their species composition and in the number of thrips found.

The aim of the study is to systematize scientific approaches to the interpretation of the concept of "economic potential", to prove the need for their conceptualization with the separation of resource-production, resource-strategic, production-strategic components and the formation of appropriate concepts on this basis. The article, based on a study of the approaches of scientists to the interpretation of the concept of "economic potential", found that the developed approaches have significant differences, and therefore there is a need for their conceptualization. Relevant concepts have been formed: resource-production, resource-strategic, production-strategic and resource-production-strategic. It is established that the resource-production concept provides a combination of economic resources and their optimal use with the ability to achieve maximum production. The resource-strategic concept involves the use of a set of resources in the process of solving problems for the future. Production and strategic concept involves the use of a set of elements with defined functions to ensure the production process and achieve strategic goals. The resource-production-strategic concept envisages the use of a set of economic resources and production opportunities to achieve the development goals of the business entity. It has been substantiated that the economic potential of the business entity is formed by two interrelated components: internal (resource-production, which reflects the potential of the business entity to produce goods (works, services)) and external (which characterizes the market). opportunities for the sale of such goods (works, services) to consumers and income). The formation of the resource-production-strategic concept in the interpretation of the concept of "economic potential" the authors put the classical approaches (production, marketing, resource), taking into account the concept of "economic potential" is defined as a set of resources and opportunities. relations can be used to the maximum in the process of solving strategic tasks. It is established that the prospect of further scientific developments in this direction is the study of structural components of economic potential and features of its formation and evaluation at different levels of economic systems.

The researchers from Lithuanian Institute of Agrarian economics confirmed that classification of Lithuanian regions by rurality into 5 groups is a more comprehensive method to reveal economic and social differences of the regions than the method used by the government at the present by classifying regions in to the problematic and non-problematic regions (Melnikienė et al., 2011). The object of the research – municipalities of different rurality degree. The objective of this paper – to analyze population density and demographic situation from 2011 to 2018 changes in municipalities of different rurality degree in Lithuania. Our research has revealed, that on average rural municipalities cover area 10 times larger than urban municipalities and 1,2 times larger than semi-urban municipalities. Taking into account population density, natural population change, net migration, old-age dependency ratio in 2011 and 2018, it was found that 10 municipalities are improving, 19 municipalities - unchanged and 16 municipalities - worsening. Keywords: population density, demographic situation, rurality, change.

<p>Research carried out by academics at higher education institutions (HEIs) has substantially contributed to nations’ development, particularly in a time of globalisation and internationalisation of higher education (HE). A range of studies on academics’ research have been undertaken in western contexts. Those studies can be classified into studies of academics’ research perceptions and studies of factors affecting academics’ research productivity. However, there has been a very limited number of studies on academics’ research capacity and HEIs’ research capacities in Vietnam. Meanwhile, the Vietnamese Government has attempted to develop its HE system to contribute to the success of its national development. Over the past ten years, the Vietnamese Government has issued a series of research related policies and has had a greater investment into the development of its HE system. However, the research capacity of Vietnamese HEIs has been lower than that of its neighbouring countries in the region. Therefore, this study was conducted with the hope that it might provide an in-depth understanding of the research capacities of Vietnamese HEIs and their academics and how they can be better fostered in the Vietnamese HE system.  The study was conducted in three public HEIs at different levels in southern Vietnam: provincial, regional, and national. The study employed an interpretive case study approach with a lens of historical and sociocultural theory. Three key tools used for data collecting were surveys, individual semi-structured interviews, and document analysis. The research participants were purposefully selected from the three institutions. For data analysis, the study utilised a combined framework adapted from the predictive model department research productivity of Bland, Center, Finstad, Risbey, and Staples (2005), the model of factors affecting academics’ research productivity of Chen, Gupta, and Hoshower (2006), and Moore’s (2015) social-ecological model: Looking beyond the individual. The study’s findings indicated that the research capacities of Vietnamese HEIs and their academics were influenced by various factors at different levels. At societal level, they include socioeconomic, sociocultural, and political factors. At community level, they comprise resources, research orientation, research networks, professional development practices. At institutional level, they consist of establishment history, geographical location, and organisation. Additionally, the study identified that institutional contexts affected the academics’ research motivation and research engagement at this level. Finally, this study suggested some recommendations for both academic leaders and academics from the three HEIs and Vietnamese HE policy makers to consider so that they may find ways to enhance the research capacities of the Vietnamese HEIs and their academics’ research engagement.</p>

The purpose of this study is to analyze the readiness of the potential economy at the developmental areas in West Bogor and to formulate a developmental economy strategy to actualize in the implementation of autonomy development. In general, the result showed that the western region of Bogor has an economic potential that can be developed, therefore it can be made as one of the main factors in the recommendation to become an autonomous district. Western Bogor region has a few growth centers to draw the growth of the region. Growth and service centers are still accumulating in urban areas resulting in a gap caused by the intensity of linkages between urban areas and rural areas in which are relatively limited.The selected strategy priorities are: (1) the development of industries that support the agricultural aspect (agro-industry) as an effort to optimize the utilization and managingsustainable natural resources by utilizing the potentials Bogor Regency has (economic conditions, government policies Bogor Regency, geographical location) as well as cooperation with private sector / other, (2) Finding and promoting the image of commodity and regional superior products that provide value-added (GDP and PAD) for the local community using the criteria of potential value-added direct a commodity / product for poor families, and (3) creating a conducive business climate to support local capacity building by expanding the local tax base and expand the productive sectors of the economy of the people.Implications of policy directed as social, cultural, political, institutional, or spatial aspects of the development budget and policy. Furthermore, the basic sector analysis should be done at sub-district unit so that it can be seen a leading sector per district based on income (GDP) per district.Keywords: Growth and service centers, local economic potential, regional development.
