The results of long-term observations on the dynamics of mortality and the dynamics of the current growth in artificial plantations of conifers are presented. In pine forest plantations, the mortality rate was analyzed depending on the planting density and on the method of creating an artificial plantation (sowing, planting). Shown is the qualitative aspect of mortality at different age stages and phases of growth of forest cultures. A conclusion is made about the natural phenomenon of the course of wave periods in relation to the number of dying trees and the dynamics of the current growth of growing trees. The undulation of the process of natural thinning of forest cultures is confined to qualitatively new restructuring of the vital structure of the tree community. It has been established that with age, the wave-like process acquires the character of attenuation and in the phase of ripeness it smoothes out significantly, finally fading out in the phase of decay.

Sustainable Economic Growth

The 2018 Nobel Economics Prize was awarded to two American economists - William D. Nordhaus and Paul M. Romer - who designed methods for better assessing environmental issues and technological advances on growth. This year’s Laureates, Nordhaus was the first person to create an intergrated model to assess interactions between society and nature and Romer laid the foundation for what is now called endogenous growth theory. According to the Swedish Royal Academy of Sciences, these two macroeconomists’ research have helped “significantly broaden the scope of economic analysis by constructing models that explain how the market economy interacts with nature and knowledge” which integrates climate change measures into long-term sustainable economic growth.

Middle Income Trap

The article is a contribution to the discussion on the necessity to change the current model of economic growth of Poland for model of economy based on knowledge and innovation. In this way, our country will be able to overcome the threats that might push the economy into the trap of the average income, expressed in long-term slowdown in GDP growth. The endogenous growth theory, formed after 1989 and characterized by duplication of Western technology, enabled relatively rapid growth by over 20 years. Currently, Poland to ensure an economic growth is facing the need for innovative technologies and innovation. Risks associated with middle income trap are very real because of the disappearance of comparative advantage, which results from relatively low labor costs. The creation in Poland conditions to accelerate economic growth requires action to increase the propensity of entrepreneurs to reach for new technologies and innovation and attractive market offer from the national centers for research and development.

Neoclassical Growth

The numerous versions of endogenous explanations of economic growth emphasize the importance of technological change driving forces, as well as the existence of appropriate institutional arrangements. Endogenous growth theory contributes to a better understanding of various experiences with long-term growth of countries and regions. It changes the key assumptions of the Neoclassical growth theory and participates in the modern regional development physiology explanation. Based on these conclusions, the paper: a) explicates the most important theoretical postulates of the theory, b) explains the most important factors of economic growth in the regions in light of the Endogenous growth theory messages and c) emphasizes the key determinants of regional competitiveness which in our view is conceptually between the phenomena of micro- and macro-competitiveness and represents their necessary and unique connection. First of all, micro-competitiveness is transformed into a regional competitiveness; then regional competitiveness is transformed into a macro-competitiveness. In turn, macro - influences the microeconomic competitiveness, and the circle is closed. After that, the process starts over again.

Drought is the most significant natural phenomenon that affects the agriculture of northern Mexico. The more drought-prone areas in Mexico fall in the northern half of the country, in the states of Chihuahua, Coahuila, Durango, Zacatecas, and Aguascalientes (figure 10.1). The north-central states form part of the Altiplanicie Mexicana and account for 30.7% of the national territory of 1,959,248 km2. This area is characterized by dry and semidry climates (Garcia, 1981) and recurrent drought periods. The climate of Mexico varies from very dry to subhumid. Very dry climate covers 21%, dry climate covers 28%, and temperate subhumid and hot subhumid climates prevail in 21% and 23% of the national territory, respectively. About 20 years ago, almost 75% of Mexico’s agricultural land was rainfed, and only 25% irrigated (Toledo et al., 1985), making the ratio of rainfed to irrigated area equal to 3. However, for the northern states this ratio was 3.5 during the 1990–98 period (table 10.1). Because of higher percentage of rain-fed agriculture, drought is a common phenomenon in this region, which has turned thousands of hectares of land into desert. Though the government has built dams, reservoirs, and other irrigation systems to alleviate drought effects, rain-fed agriculture (or dryland farming) remains the major form of cultivation in Mexico. In Mexico, there is no standard definition for agricultural drought. However, the Comisión Nacional del Agua (CNA; i.e., National Water Commission), which is a federal agency responsible for making water policies, has coined its own definition for drought. This agency determines whether a particular region has been affected by drought, by studying rainfall records collected from the national climatic network. The national climatic network is spread throughout the country and is managed by the Servicio Meteorológico Nacional (SMN; i.e., National Meteorological Services). The CNA determines, for a municipal region, if the rainfall is equal to or less than one standard deviation from the long-term mean over a time period of two or more consecutive months. If it is, then the secretary of state declares drought for the region.

Forests and water are closely related to each other. Thus, forest management is crucial for the sustainable clean water supply. Forest thinning is one of the fundamental forest management practices, as it can change runoff by controlling the density of trees. In this study, the effect of forest thinning on long-term runoff changes was evaluated, based on the long-term rainfall-runoff data of a coniferous plantation forest catchment in Korea. From the double mass curve and Pettitt’s test, a statistically significant increase in runoff rates was identified. A simple linear regression model of the double mass curve can successfully quantify the net effect of forest thinning on the runoff increase. Furthermore, it was also confirmed that forest thinning does not significantly increase the risk of flooding. About ten years after forest thinning, crown closure rates of the coniferous plantation forest reached a level similar to the pre-thinning period, and runoff rates returned to the pre-thinning level, due to forest growth. As a result of this study, a proposed direction for Korea’s forest policy for water resource management is presented for the future.

Mentoring is known to promote development of professional skills irrespective of the discipline. It is a natural phenomenon that emanates from the desire of a senior and experienced individual to give and the need of an inexperienced novice to grow. Mutual trust, faith and respect while working towards a shared vision of objectives and achievements are the main driving force of a mentoring relationship. It requires the mentor to give selflessly and the mentee to accept graciously while conveying his needs and being an active partner in the process. A mentor is looked upon as a guide, confidante, counselor, teacher, friend, supporter, and much more in professional and career development as well as psychosocial or personal aspects. The mentee is expected to take a proactive role in guiding and managing the process. Despite a clear need for mentoring during and after medical school, very few medical schools in India foster this relationship. Most have student advisor programs or counseling cells that are oriented primarily to problem solving. There is also a lack of full understanding of the roles of a mentor or a mentee even though the terms are used rather frequently. A mentoring relationship could be formally established as a part of an institutional or departmental mentoring program, long term or short term, with a specific purpose; or, for overall career progression, individual or in a small group. Also, the mentees’ requirements at different stages of training and career may decide the type of mentoring relationship. The needs of a first year medical undergraduate student are different from those of a final year student or a postgraduate resident. There is an imminent need to train the medical school faculty in mentoring skills and orient the students to ‘mentor-mentee relationship’.
