Possibilities of the Integration of the Method of the Ecologically Oriented Independent Scientific Research in the Study Process

The aim of this paper is to analyse possibilities of the integration of the method of the ecologically oriented independent scientific research in the study process. In order to achieve the set aim, the following scientific research methods were used: analysis of the conceptual guidelines for the development of environmentally oriented entrepreneurship, interpretation of the experts' evaluation of the ecologically oriented management, analysis of the results of the students' ecologically oriented independent scientific research, as well as monographic and logically constructive methods. The results of the study give an opportunity to make conclusions and to develop conceptual recommendations on how to introduce future economics and business professionals with the theoretical and practical aspects of ecologically oriented management during the study process.

Abstract

Housing market participants constantly face the housing heterogeneity - the technical and socio-economic differences of dwellings in a certain populated area. Housing heterogeneity often complicates the managerial decision making related to housing transactions, identification and objective evaluation of the quantitative and qualitative aspects of transactions. Housing heterogeneity is an objective phenomenon that implies housing uniqueness - housing distinguishing characteristics divided into specific and interconnected groups within the framework of the research. Most of these differences can be noticed by each market participant, but some of them can be identified only by experienced and professionally trained market participants. Theory and practice have demonstrated that the constituent groups of heterogeneity influence each other and take part in the formation of market value and transaction price of housing units. The increased housing construction intensity, the continuous modernisation of construction technologies and the diversification of building materials used in housing construction, as well as restriction of the building plot of land change the quantitative and qualitative aspects of heterogeneity dimensions. This poses considerable challenges to market participants in the managerial decision making process related to housing transactions. Research results demonstrate that the socio-economic elements of housing heterogeneity are constantly changing under the influence of the dominating factors of the external and internal environment. Therefore, nowadays, housing heterogeneity has become a major cause of information asymmetry, which means that heterogeneity is inherent in the formation of socio-economic market barriers in the housing market.

Abstract

There exists sharp competition amongst nations regarding the increasing foreign investments; therefore, nations are willing to offer foreign investors and their families some type of political bonus, such as temporary residence permit, permanent residence permit, or even citizenship. The simplest way to entice investors is to offer them and their family members temporary residence permits in exchange for investments - simply by purchasing real property (via the so-called “Golden Visa” program). Such a program was launched in Latvia in 2010; however, significant limitations were placed on it in 2014. This research (1) compares the “Golden Visa” programs in different countries in the world, (2) determines the impact of the program on the real property market of Latvia, and (3) searches for the main reason why limitations were applied to the temporary residence permit program in 2014, which resulted in a significant decrease in the international investments in Latvia (this part of the paper is based on the results of the following research: Viesturs, J., Auziņš, A., & Štaube, T. (2017). Arguments Used for Restricting International Real Property Transactions: Case Study of Latvia).

The First Evidence of Familial Lung Cancer in Latvia by Population Screening for Hereditary Cancer

Introduction. Lung cancer is the major worldwide cause of tumour lethality. Recently, the role of heredity in lung carcinogenesis has become an important scientific target. While there is ongoing search for the respective gene mutations, it was suggested that presence of at least 2 first-degree relatives with lung cancer should reveal the familial lung cancer.

Aim of the study. We present the first documented evidence of familial lung cancer in Latvia by population screening data in order to improve the planning of early cancer diagnostics. Materials and methods. The investigation was designed as population screening for hereditary cancer. Family cancer history was obtained from 18642 adults in the Valka district (76.6% of the adult population). Data analysis and proband consultations were performed in Hereditary Cancer Institute. Hereditary cancer syndromes were diagnosed by clinical criteria.

Results. Familial lung cancer syndrome was diagnosed in 13 probands, but suspected familial lung cancer syndrome (sFLC) - in 93 probands, corresponding to the frequency 0.6% (95% confidence interval (CI) = 0.5-0.7%). The frequency of lung cancer among blood relatives was 25.5% (95% CI = 19.3-32.8%) in definitive and 17.2% (95% CI = 15.0-19.7%) in suspected syndrome groups exceeding significantly the cumulative risk for EU population. Number of affected generations was significant for sFLC. The age of cancer onset did not influence the frequency of cancer. The data about the cancer course are described. Conclusions. The high frequency of lung cancer in the identified pedigrees supports the role of familial factors in the lung carcinogenesis as well as the practical value of our diagnostic criteria helping to identify high-risk group for intervention measures to prevent lung cancer.

Intragastric Migration of Swedish Adjustible Gastric Band

Swedish adjustable gastric banding (SAGB) is an operative procedure meant for the treatment of morbid obesity. It is characterised by application of low-pressure, high-volume device upon the stomach. One of the major complications, currently described in 6% of patients, is the intragastric migration of the adjustable gastric band. The removal of the band is the gold standard in these cases and must be performed either urgently or as a scheduled manipulation according to the symptoms. We present a thoroughly documented case of surgical obesity treatment by SAGB complicated by intragastric band migration as well as our experience in settling the complication.

Summary

Endometriosis is characterised by the presence of ectopic functional endometrial tissue outside the uterus. The disease most frequently affects pelvic tissues and organs but any site can be involved including gastrointestinal tract, lungs and other organs. Extra-pelvic endometriosis mostly occurs in females aged 35–40 years. Here we report a well-documented, morphologically proved and surgically treated case of pulmonary endometriosis in a 50-year-old woman in order to heighten the awareness of endometriosis as the differential diagnosis for nodular lung lesions.

Abstract

The development of the real estate market contributes to the development of the national economy, thus creating a favourable investment climate for the investors. Increase in the level of the incomes of the inhabitants may increase the availability of housing in the country by fiscal and monetary policy instruments. The topicality of the paper is related to the need for analysis of the trends and prospects of the real estate market development of the Baltic States, as it has a high social meaning and has a high importance for market participants. The objective of the research is to analyse influencing factors and tendencies of real estate market development in Baltic States, and includes a comparative analysis of the residential property market in the Baltic States is conducted. The research methods used in the paper are statistical data analysis, historical and logical approach methods. The article focuses mainly on the housing market. It was concluded in the study that under the similar geographic and economic conditions in the Baltic States, the housing affordability index and real estate market development tendencies have many differences and success indicators are still varying.

Abstract

Despite the fact that the appendix is one of the rarest anatomic localization of neuroendocrine tumours (NETs) in the digestive system, the appendicular neuroendocrine tumour (A-NET) remains among the most common tumours of the appendix. The A-NET usually presents as a small solitary lesion revealed only after pathological examination of appendix that has been surgically removed for acute appendicitis. Only 18 papers in the Pubmed database (1965-2012) are dedicated to A-NET in pregnancy. Here we present a well-documented case of A-NET in a pregnant lady.
