“…Accordingly, it is concluded that school principals use their expertise power the most among the power resources sub-dimensions. When the literature is examined [1,18,21,22,25,32,78], it is seen that similar results have been observed. However, there have also been studies in the literature with different results; studies in which the reward power is the highest [9,13,24,79,80], studies in which the legal power is the highest [81], studies in which charismatic power is the highest [10,14,20,82], and the studies with the highest frequency of connection power [18].…”

“…There are many studies in the literature about power supplies. The terms job satisfaction and satisfaction [1,2,[9][10][11][12], organizational commitment [2,13,14], leadership styles and characteristics [15,16], job performance [17][18][19], organizational silence [20,21] organizational cynicism [22], organizational trust [23], organizational climate [24], job stress [17], dedication to work [25] have been found to be related. Studies have focused on the effects of organizational power on the organization and its employees.…”

In this study, we examined the effects of the organizational power resources used by school principals on teachers' work alienation and trait anxiety levels. Then, we examined the mediating role of trait anxiety in the relationship between organizational power resources and work alienation. We used the correlational scanning model and mediation model in the research. The research sample consists of 400 teachers working in Turkish public schools. In our research, "Organizational Power Scale in Schools", "Work Alienation Scale" and "Trait Anxiety Scale" were used. As a result of the research, we found significant relationships between the variables. Accordingly, there is a positive relationship between trait anxiety and work alienation, a positive relationship between trait anxiety and coercive power and legal power, a negative relationship between trait anxiety and expert, charismatic and reward power, a positive relationship between work alienation and coercive power, and a positive relationship between work alienation and reward power. Negative relationships were observed between expertise and charismatic power. Finally, it was determined that trait anxiety had a mediating role in the relationship between the power resources used by school principals and the level of work alienation of teachers.

“…The trial area is between 37°35′36 ″ north latitude and 36°49′20 ″ east longitude and approximately 508 m above sea level. The average precipitation and temperature are 719.7 mm and 16.6 °C, and the Mediterranean climate is dominant in experimental area (Uzun et al, 2018). The physical and chemical properties of the lysimeter soil are given in Tables 1 and 2.…”

Many minerals such as especially nitrogen leaching out from the soil in exceed precipitation leach. This situation is a very important factor causing economic losses and environmental pollution. The aim of the study is to determine amount of the nitrogen leaching from the soil by precipitation outside the irrigation season from a weighing lysimeter controlled by a programmable logic controller (PLC). The research was carried out under Kahramanmaraş conditions in the five-month period between December 2018 -April 2019. In the study, a weighed lysimeter with a diameter of 113 cm (1 m 2 ) and a depth of 130 cm was used and on which three-year-old (Maraş 18) walnut was planted. Two pluviometers were used to measure the amount of precipitation falling on lysimeter and the drained water from it. At the beginning of the experiment, 300 gr DAP (diammonium phosphate) fertilizer was applied to the lysimeter soil. A PLC automation system has been created that controls lysimeter and pluviometers for the research. The PLC automation system measured a total precipitation of 868.1 mm and drainage water of 686.6 mm Nitrogen concentrations and loads in the drainage water were determined from 26 water samples taken in the experimental period. In analysis of water samples, it was determined that nitrogen of 12.7 kg was leached from the soil of one hectare with the effect of precipitation. The leaching amount of nitrogen was 8.4%, of which 24% was in the form of ammonium (NH4) and 76% in the form of nitrate (NO3). The highest nitrogen leached with 5.4 kg per hectare in December, when the precipitation was the highest (264.1 mm). According to the results, as amount of precipitation increased, the leaching amount of nitrogen increased leach. Therefore, application programs of nitrogen fertilizer should be prepared by taking into consideration the precipitation regime of the region. It is very important for economy, the environment and human health.

“…The climate induced warming in the Himalaya is experiencing faster rates (0.06 °C/year) than predicted for the other regions of the world 11 – 13 , raising the likelihood of species extinction in these vulnerable regions. Analyses of temperature trends have shown that temperature increases are greater at the higher altitudes than in the lowlands 14 . Studies suggest that a 0.3 °C rise in global mean temperature per decade will result in potential rise of the global mean surface temperature of about 1–3.5 °C by 2100 15 .…”

In the era of anthropocene, global warming tends to alter the distribution range of the plant species. Highly fragile to such changes are the species that are endemic, inhabit higher elevations and show narrow distribution ranges. Predicting and plotting the appropriate suitable habitats and keeping knowledge of how climate change will affect future distribution become imperative for designing effective conservation strategies. In the current study we have used BIOMOD ensemble forecasting to study the current and predict the future potential distribution of Dactylorhiza hatagirea and Rheum webbianum and describe their niche dynamics in Himalayan biodiversity hotspots under climate change scenarios using ecospat R package. Results reveal sufficient internal evaluation metrics with area under curve (AUC) and true skill statistic (TSS) values greater than 0.8 i.e. 0.93 and 0.98 and 0.82 and 0.90 for D. hatageria and R. webbianum respectively, which signifies robustness of the model. Among different bioclimatic variables, bio_1, bio_3, bio_8, bio_14 and bio_15 were the most influential, showing greater impact on the potential distribution of these plant species. Range change analysis showed that both the studied species will show significant contraction of their suitable habitats under future climatic scenarios. Representative Concentration Pathway (RCP) 8.5 for the year 2070, indicate that the suitable habitats could be reduced by about 51.41% and 70.57% for D. hatagirea and R. webbianum respectively. The results of the niche comparisons between the current and future climatic scenarios showed moderate level of niche overlap for all the pairs with D. hatageria showing 61% overlap for current vs. RCP4.5 2050 and R. webbianum reflects 68% overlap for current vs. RCP4.5 2050. Furthermore, the PCA analysis revealed that climatic conditions for both the species vary significantly between current and future scenarios. The similarity and equivalence test showed that the niche between present and future climate change scenarios is comparable but not identical. From the current study we concluded that the influence of climate change on the habitat distribution of these plant species in the Himalayan biodiversity hotspots can be considered very severe. Drastic reduction in overall habitat suitability poses a high risk of species extinction and thereby threatens to alter the functions and services of these fragile ecosystems. Present results can be used by conservationists for mitigating the biodiversity decline and exploring undocumented populations on one hand and by policymakers in implementing the policy of conservation of species by launching species recovery programmes in future on the other. The outcomes of this study can contribute substantially to understand the consequences of climate change in the Himalayan biodiversity hotspots.
