Investigation of forest areas in subalpine zone towards alpine zone by effect of climate change
No full textİklim değişiminin Artvin ve Rize illeri sınırları içerisinde bulunan toplam 3 yörede 2000 m ve üzerinde bulunan alpin zon sınırında aşağı ya da yukarı yönde bir değişimin olup olmadığı araştırılmıştır. Orman sınırı, ağaç sınırı ve bodur (kötürüm) ağaç sınırını içine alan 5m x 20m boyutlarında (100 m2) 9 farklı mevkii de 40 adet deneme alanı oluşturularak bu alanların bakısı, yükseltisi (m), eğimi (%), 3 m den boylu ağaçların boyları, çapları ve yaşları belirlendi. Çalışma sonucuna göre; yöreler arasında (Artvin- Merkez, Artvin- Yusufeli ve Rize- Çamlıhemşin) çap, boy ve yaş bakımından orman üstü zonlarda belirgin farklılık görülmezken, Artvin- Merkez ile Rize- Çamlıhemşin yörelerinde kendi içlerinde yükseklik değişimleri ile birlikte çap, boy ve yaş değerleri bakımından önemli farklılıklar ortaya çıkmıştır. Bu çalışma sonucunda özellikle Artvin- Merkez ve Rize- Çamlıhemşin yörelerinde orman üst zonunun küresel iklim değişimi etkisi ile daha üst rakımlara taşındığı düşünülmektedir.We investigated that climate change affected to alpine zone whether or not change in the down or upward direction in the 3 regions (2000 m and above) within the boundaries of Artvin and Rize. The study area consist of forest border, treline and squat (crippled) tree line and located 9 different regions with a total of 40 experiment areas. The size of the each experimented area was 5 m x 20 m (100 m2). At the same time, we determined that aspects, altitude (m), slope (%) and tree diameter, age and height for taller than 3 m trees in the each study area. According to the study results; there were not significant differences between region (Artvin Central, Artvin-Yusufeli and Rize- Camlihemsin) of top forest zones, compared to diameter, lenght and tree ages. But, there were a significant differences between Artvin-Central and Rize- Camlihemsin compared to diameter, lenght and ages with elevation changes. The result indicated that, the upper zone of the forest moved to higher altitutes, because of the effects of global climate change in the Artvin- Central and Rize- Camlihemsin regions
Understanding mobile phone usage while driving: Mini-bus and taxi drivers' experiences in Istanbul
No full textDevletkuşu, Canan (Dogus Author)In emerging markets, the amount of mobile communication and the number of occasions mobile phones are used are increasing. More and more settings appropriate or not for mobile phone usage are being exposed. Although prohibited by many governments, there is evidence that use of new mobile devices while driving are somehow becoming current everyday practice, hence legitimatizing usage for many users. Dominant dangerous behavior in the absence of enforced legal framework is being deployed and has become routine for many m-users. This chapter adopts a qualitative case study approach (20 cases) to examine the public transport drivers' motives, logic and legitimacy processes. The question which these issues raise in the light of advancing m-technologies is: How do, in the context of emerging market, undesired emerging routines enactment get to be reflected upon and voluntarily disregarded to maximize the benefits of m-technologies while minimizing their drawbacks? Findings point out at multiple motives for usage including external social pressure through the ubiquitous 24/7 usage of mtechnology, lack of alternative communication protocol, real time need for action and from an internal perspectives boredoms, lack of danger awareness, blurring of the boundaries between personal and business life and lack of job fulfillment are uncovered as key factors. As secondary dynamic factors such as education, drivers work' histories, impunity, lack of strong consumer opposition appear central in shaping the development of the routines

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Data and data analysis script supporting Is Fair Representation Good for Children? Effects of Electoral Partisan Bias in State Legislatures on Policies Affecting Children’s Health and Well-Being
No full textThe files include the "readme for the partisan bias study" text document that provides an overview of the study and details about the other two files, the Excel file that has all the raw data for the study (Partisan bias study data.xls) and the R script used to analyze the data (Partisan bias study R script).Increasing evidence suggests that state policies impact constituents' health, but political determinants of health and health inequities remain understudied. Using state and year fixed-effects models, we determined the extent to which changes in electoral partisan bias in lower chambers of U.S. state legislatures (i.e., discrepancy between statewide vote share and seat share) were followed by changes in five state policies affecting children and families (1980-2019) and a composite of safety net programs (1999-2018). We examined effects on each policy and whether the effect was modified when bias was accompanied by unified party control. Next, we determined whether the effect differed depending on which party it favored. Less bias resulted only in higher AFDC/TANF benefits. Both pro-Democratic and pro-Republican bias was followed by decreased AFDC/TANF benefits and increased Medicaid benefits. AFDC/TANF recipients, unemployment benefits, minimum wage, and pre-K-12 education spending increased following pro-Democratic bias and decreased following pro-Republican bias. Estimated effects on the composite measure of safety net policies were all close to null. Some effects were modulated by unified party control. Results demonstrate that increasing fairness in elections is not a panacea by itself for increasing generosity of programs affecting children’s well-being. Indeed, bias can be somewhat beneficial for the expansiveness of some policies. Furthermore, with the exception of unemployment benefits and AFDC/TANF recipients, Democrats have not been using the additional power that comes with electoral bias to spend more on major programs that benefit children. Finally, after decades in which electoral bias was in Democrats’ favor, bias has started to shift toward Republicans in the last decade. This trend forecasts more cuts in almost all the policies in this study, especially education and AFDC/TANF recipients. There is a need for more research and advocacy emphasis on the political determinants of social determinants of health, especially at the state level.NoneKaratekin, Canan; Mason, Susan M.; Latner, Michael; Gresham, Bria; Corcoran, Frederique; Hing, Anna; Barnes, Andrew J..

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Genesis of the hydrothermal gold deposits in the Canan area, Lepaguare District, Honduras
No full textThe Canan area (Honduras) is characterized by a gold-bearing ore deposit that is associated with quartz-veined shear zones. Gold mineralization occurs in low-to medium-grade metamorphic host-rocks (graphitic and sericitic schists). Hydrothermal fluids, which are associated with the emplacement of Cretaceous-Tertiary granodioritic intrusions, are responsible for the formation of quartz veins and the hydrothermal alteration of wall-rocks. Three main altered zones have been detected in the wall-rocks as far as 150 cm from the quartz veins. The distal zone (up to 50-cm thick) contains quartz, chlorite and illite. The intermediate zone is the thickest (up to 80 cm) and is marked by quartz, muscovite, sulphides, kaolinite and native elements such as Au and Ag. The proximal zone, which is close to the quartz veins, is rather thin (up to 25 cm) and contains clay minerals, Al-oxides-hydroxides and sulphides. The transition from the distal to the proximal zone is accompanied by the enrichment of SiO2 and the depletion of all other major elements, except for Fe2O3(tot). Precious metals occur in the highest concentrations in the intermediate zone (Au up to 7.6 ppm and Ag up to 11 ppm). We suggest that gold was transported as a reduced sulphur complex and was precipitated from the hydrothermal solution by the reaction of the sulphur complexes with Fe2+ from the alteration of the mafic minerals of the host-rock. Fluid–wall-rock interactions seem to be the main cause of gold mineralization. Genetic relationships with a strike-slip fault system, hydrothermal alteration zones within the metamorphic wall-rocks, and an entire set of geochemical anomalies are consistent with orogenic-type gold deposits of the epizonal clas
Competitiveness of Turkeys Organic Exports in the European Union Market
No full textTurkeys exports of organically produced agricultural products have been rapidly growing particularly in response to increasing demand in the European Union countries. Common view and findings of the research on organic trade in Turkey confirms that European market is expanding. A lacking component of the existing research on Turkeys organic exports is that none of the studies focused on modeling the export market for organic products which would enable to make forecasts as well as to make analysis for policy implications. Another missing component of the stream of studies on trade of Turkish organic commodities is the lack of understanding of the present situation of the competitiveness of Turkish exports in the European Union market. The study therefore focuses on estimating an econometric export demand function for organic products and exploring the competitiveness and export performance of Turkish exports as well as understanding the components of export performance. An effort to estimate an econometric export demand model for Turkeys organic exports and revealing sources of export performance and competitiveness is what makes the present study a unique one. The project has three major objectives and thus seeks to produce three outputs: The first objective is to estimate an export demand model for Turkish organic products in the European Union market. It is therefore possible to estimate price and income elasticities of demand as well as to make projections. The second objective is to explore Turkeys export competitiveness in organic products in the European Union market. It order to fulfill this objective, we will estimate indices to measure Turkeys competitiveness. The third objective is to investigate export competitiveness and determine the components of export performance. Through constant market share analysis, we seek to determine the key factors underlying the growth or Turkeys organic exports. The study reveals that export demand for the Turkish organic products are growing and sensitive to price and income changes in target countries. Turkey has a clear comparative advantage against the rival EU countries in selected products. Competitiveness is particularly due to relative prices, thus does not indicate a sustainable competitiveness due to lack of added value in the export items.Organic Agriculture, Turkish Agriculture, Export Demand, Competitiveness, Turkish Organic Exports, International Relations/Trade, Livestock Production/Industries,
