Can Tube Tunnel Crossings Relieve Urban Congestion Problems? Izmir Tube Tunnel Project Proposal Under Scrutiny
Authors: Duvarcı Yavuz , Yigitcanlar Tan
Published: May 2019

Building underwater tube tunnel crossings to ease the urban congestion problems has become a popular approach for many cities across the globe. London, New York, Istanbul, Hamburg, Sydney and Brisbane are among these cities. However, the effectiveness and externalities of these expensive mega urban infrastructures have also been questioned widely among urban, transport and environmental planning scholars. Given the international popularity of the topic, this study places a new tube tunnel crossings project from Izmir, Turkey under the microscope. In this heuristic simulation study, policy-on scenarios were tested to determine possible impacts of the underwater tube tunnel-crossing project. The traffic impacts are discussed using simulations assigning the initial origin–destination data. The results of the study revealed that, given the two locations, outer and inner locations over the dagger-shape bay, the capacity increments on the bridge links and the links around the periphery highway did not bring any effective solutions beyond some minor improvements. The findings disclosed that the ineffectiveness of the tube tunnel crossing might be due to the excessive congestion happening all over the downtown area, which clogs the passageways to the bridge. The paper highlights the limitations of the tube tunnel-crossing project, emphasises the need for comprehensive investigations before committing to the project and advocates the emphasis to be actually given for sustainable mobility.
Social Interaction Scaling for Contact Networks
Authors: Ghafoor Yusra , Chen Yi-Shin , Chen Kuan-Ta
Published: May 2019

Urbanization drives the need for predictive and quantitative methods to understand city growth and adopt informed urban planning. Population increases trigger changes in city attributes that are explicable by scaling laws. These laws show superlinear scaling of communication with population size, asserting an increase in human interaction based on city size. However, it is not yet known if this is the case for social interaction among close contacts, that is, whether population growth influences connectivity in a close circle of social contacts that are dynamic and short-spanned. Following this, a network is configured, named contact networks, based on familiarity. We study the urban scaling property for three social connectivity parameters (degree, call frequency, and call volume) and analyze it at the collective level and the individual level for various cities around the world. The results show superlinear scaling of social interactions based on population for contact networks; however, the increase in level of connectivity is minimal relative to the general scenario. The statistical distributions analyze the impact of city size on close individual interactions. As a result, knowledge of the quantitative increase in social interaction with urbanization can help city planners in devising city plans, developing sustainable economic policies, and improving individuals’ social and personal lives.

Published: May 2019

This study clarifies whether vegetation can promote the decrease of indoor PM2.5 concentration. The indoor PM2.5 concentration in two periods of 2013 in Wuhan city was simulated by cigarette burning in a series of sealed chambers. Six common indoor potted plants were selected as samples to investigate the effect of plants on PM2.5 decline. The effects of potted plants on PM2.5 decline were analyzed from three aspects: plant species, leaf characteristics and relative humidity. The results show that the presence of potted plants accelerated the decline of PM2.5. The additional removal rates (excluding gravity sedimentation of PM2.5 itself) for Aloe vera and Epipremnum aureum were 5.2% and 30% respectively, when the initial PM2.5 concentration was around 200 μg/m3. The corresponding values were 0% and 17.2%, respectively, when the initial PM2.5 was around 300 μg/m3. Epipremnum aureum was the optimum potted plant for PM2.5 sedimentation, due to its rough and groove leaf surface, highest LAI (leaf area index, 2.27), and strong humidifying capacity (i.e., can promote chamber humidity to 65% in 30–60 minutes.). Actual indoor studies have also confirmed that a certain amount of Epipremnum aureum can promote the decrease of indoor PM2.5. This paper provides insights on reducing the concentration of fine particulate matter by indoor greening efforts.
Determination of the Agricultural Eco-Compensation Standards in Ecological Fragile Poverty Areas Based on Emergy Synthesis
Authors: Gao Yang , Han Ziyan , Cui Yanzhi , Zhang Hanbing , Liu Lulu
Published: May 2019

Eco-compensation is an important mechanism when applying the theory of ecosystem services to practical development, which translates the external and non-market value of the environment into real financial incentives for local actors. Scientifically formulating feasible and credible compensation standards is the most critical and key step to adjusting the benefits received by environment protectors and beneficiaries. The Inner Mongolia agro-pastoral zone is an important ecological area with an undeveloped economy in Northern China. The implementation of eco-compensation policies contributes to ecological restoration and poverty alleviation. Taking Horqin Left Back Banner, Inner Mongolia, China as a study case, a quantitative model of a non-point source pollution eco-compensation program was established by using emergy synthesis—a thermodynamics-based method in ecological economic systems—to create a comprehensive eco-compensation standard. The results showed that the eco-compensation amounts for non-point source pollution were generally below 10% of the regional gross domestic product (GDP). A 11–20% reduction in fertilizer would be accepted according to the field investigation and the optimal eco-compensation strategy reduced the phosphate fertilizer application by 20% with a compensation standard of $379.63/ha/year, which was similar to the farmers’ willingness to accept compensation. For the accurate creation of a non-point source pollution eco-compensation program, the emergy synthesis overcomes the inconsistency in the quantification of the material flow, ecological flow, and economic flow, guaranteeing the sustainable implementation of non-point source pollution eco-compensation projects.

Published: May 2019

The aim of this study is to investigate the existence of solutions for a non-linear neutral differential equation with an unbounded delay. To achieve our goals, we take advantage of fixed point theorems for self-mappings satisfying a generalized ( α , φ ) rational contraction, as well as cyclic contractions in the context of F -metric spaces. We also supply an example to support the new theorem.
Particle Fluctuations in Mesoscopic Bose Systems
Authors: Yukalov Vyacheslav I.
Published: May 2019

Particle fluctuations in mesoscopic Bose systems of arbitrary spatial dimensionality are considered. Both ideal Bose gases and interacting Bose systems are studied in the regions above the Bose–Einstein condensation temperature T c , as well as below this temperature. The strength of particle fluctuations defines whether the system is stable or not. Stability conditions depend on the spatial dimensionality d and on the confining dimension D of the system. The consideration shows that mesoscopic systems, experiencing Bose–Einstein condensation, are stable when: (i) ideal Bose gas is confined in a rectangular box of spatial dimension d > 2 above T c and in a box of d > 4 below T c ; (ii) ideal Bose gas is confined in a power-law trap of a confining dimension D > 2 above T c and of a confining dimension D > 4 below T c ; (iii) the interacting Bose system is confined in a rectangular box of dimension d > 2 above T c , while below T c , particle interactions stabilize the Bose-condensed system, making it stable for d = 3 ; (iv) nonlocal interactions diminish the condensation temperature, as compared with the fluctuations in a system with contact interactions.
A Pairing-Based Three-Party Authenticated Encryption Scheme without Shared Secrets
Authors: Lin Han-Yu
Published: May 2019

The Traditional Authenticated Encryption (AE) scheme is a single-user cryptographic mechanism which only enables one designated verifier to authenticate the ciphertext. Although several group-oriented AE variants have also been proposed to eliminate such a limitation, they require shared verification. This motivated us to think of a scenario of three-party communication environments where each party runs independent processes without cooperation. In this paper, we realize a novel three-party AE (abbreviated to TPAE) scheme in which two designated verifiers can solely decrypt the same ciphertext and then inspect the validity of embedded signature. Additionally, we also show that our TPAE construction is computationally secure using the well-defined IND-CCA2 and the EF-CMA adversary games in the proof model of random oracles. The comparison results will demonstrate the computational efficiency of our mechanism.
The Bessel Expansion of Fourier Integral on Finite Interval
Authors: Zhou Yongxiong , Zhao Zhenyu
Published: May 2019

In this paper, we further extend the Filon-type method to the Bessel function expansion for calculating Fourier integral. By means of complex analysis, this expansion is effective for all the oscillation frequencies. Namely, the errors of the expansion not only decrease as the order of the derivative increases, but also decrease rapidly as the frequency increases. Some numerical experiments are also presented to verify the effectiveness of the method.

Authors: Abdel-Basset Mohamed , Mohamed Mai , Chang Victor , Smarandache Florentin
Published: May 2019

Many companies have observed the significant benefits they can get via using internet. Since then, large companies have been able to develop business transactions with customers at anytime, anywhere, and in relation to anything, so that we now need a more comprehensive concept than the internet. This concept is the Internet of Things (IoT). IoT will influence decision making style in various phases of selling, buying and marketing process. Therefore, every individual and company should know precisely what IoT is, and how and why they should incorporate it in their operations. This motivated us to propose a smart system based on IoT to help companies and marketers make a powerful marketing strategy via utilizing obtained data from IoT devices. Not only this, but the proposed system can also solve the problems which face companies and customers in online shopping. Since there are different types of the same product, and also different criteria for purchasing which can be different between individuals, customers will need a decision support system to recommend them with the best selection. This motivates us to also propose a neutrsophic technique to deal with unclear and conflicting information which exists usually in the purchasing process. Therefore, the smart system and neutrosophic technique is considered as a comprehensive system which links between customers, companies, marketers to achieve satisfaction for each of them.

Published: May 2019

The main purpose of this paper is to give several identities of symmetry for type 2 Bernoulli and Euler polynomials by considering certain quotients of bosonic p-adic and fermionic p-adic integrals on Z p , where p is an odd prime number. Indeed, they are symmetric identities involving type 2 Bernoulli polynomials and power sums of consecutive odd positive integers, and the ones involving type 2 Euler polynomials and alternating power sums of odd positive integers. Furthermore, we consider two random variables created from random variables having Laplace distributions and show their moments are given in terms of the type 2 Bernoulli and Euler numbers.
Basic Concepts of Riemann–Liouville Fractional Differential Equations with Non-Instantaneous Impulses
Authors: Agarwal Ravi , Hristova Snezhana , O’Regan Donal
Published: May 2019

In this paper a nonlinear system of Riemann–Liouville (RL) fractional differential equations with non-instantaneous impulses is studied. The presence of non-instantaneous impulses require appropriate definitions of impulsive conditions and initial conditions. In the paper several types of initial value problems are considered and their mild solutions are given via integral representations. In the linear case the equivalence of the solution and mild solutions is established. Conditions for existence and uniqueness of initial value problems are presented. Several examples are provided to illustrate the influence of impulsive functions and the interpretation of impulses in the RL fractional case.
A Neurodevelopmental Model of Combined Pyrethroid and Chronic Stress Exposure

Published: May 2019

Attention-deficit hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders of childhood and previous studies indicate the dopamine system plays a major role in ADHD pathogenesis. Two environmental exposures independently associated with dopaminergic dysfunction and ADHD risk include exposure to deltamethrin, a pyrethroid insecticide, and chronic stress. We hypothesized that combined neurodevelopmental exposure to both deltamethrin and corticosterone (CORT), the major stress hormone in rodents, would result in additive changes within the dopamine system. To study this, we developed a novel dual exposure paradigm and exposed pregnant C57BL/6 dams to 3 mg/kg deltamethrin through gestation and weaning, and their offspring to 25 μg/mL CORT dissolved in the drinking water through adulthood. Midbrain RNA expression as well as striatal and cortical protein expression of key dopaminergic components were investigated, in addition to ADHD-like behavioral tasks and electrochemical dopamine dynamics via fast-scan cyclic voltammetry. Given the well-described sexual dimorphism of ADHD, males and females were assessed separately. Males exposed to deltamethrin had significantly decreased midbrain Pitx3 expression, decreased cortical tyrosine hydroxylase (TH) expression, increased activity in the Y maze, and increased dopamine uptake rate in the dorsal striatum. These effects did not occur in males exposed to CORT only, or in males exposed to both deltamethrin and CORT, suggesting that CORT may attenuate these effects. Additionally, deltamethrin- and CORT-exposed females did not display these dopaminergic features, which indicates these changes are sex-specific. Our results show dopaminergic changes from the RNA through the functional level. Moreover, these data illustrate the importance of testing multiple environmental exposures together to better understand how combined exposures that occur in certain vulnerable populations could affect similar neurodevelopmental systems, as well as the importance of studying sex differences of these alterations.
Hepatocellular Carcinoma Recurrence in HCV Patients Treated with Direct Antiviral Agents
Authors: Sanduzzi-Zamparelli Marco , Boix Loreto , Leal Cassia , Reig María
Published: May 2019

The risk of hepatocellular carcinoma recurrence is universal regardless of the treatment modality applied, and secondary prevention is still an unmet issue even though the elimination of hepatitis C (HCV) with direct antiviral agents (DAAs) was expected to be one of the new options. Unfortunately, the impact of DAAs on hepatocellular carcinoma (HCC) development (de novo and recurrence) is still controversial. Since the first publication on the subject in 2016, almost all groups worldwide have carried out research in this field with hundreds of publications now available. This revision is focused on the impact of DAAs on HCC recurrence and aims to discuss the potential underlying mechanisms and host factors pointing out the time association phenomenon between DAA treatment and HCC recurrence. Moreover, we comment on the methodological issues that could affect the different interpretations of the published results. In conclusion, this is an area of research with potential in the understanding of the impact of factors not previously considered, and may also help change hepatocarcinogenesis tenets, such as the belief that the elimination of HCV should be used as a second prevention treatment.

The surfaces of saline lakes are shrinking at a threatening rate worldwide. Likewise, the Uchhali complex (formed by three saltwater lakes located in the Salt Range, Pakistan) that serves as a major regional source of water for humans and as a habitat for water birds must be monitored. With this objective in mind, we conducted a study coupling hydrochemistry and stable isotope compositions (δ37Cl, δ18O and δD) in order to characterize its hydrochemical properties and the main processes controlling them. Results showed that the Uchhali complex salinity has dramatically increased compared to other similar lakes in the world. While the Uchhali (UL) and Khabbeki (KL) lakes present a sodium-chloride hydrofacies, the Jahlar (JL) is of a sodium-bicarbonate type. Hydrochemistry parameters indicate that the weathering of surrounding rocks is the major vector for the increase of total dissolved solids in the water. On the other hand, the observed enrichment in heavy isotopes of the water stable isotope compositions implies that the different lakes are undergoing a long history of intense evaporation. The study of the corresponding δ37Cl isotope compositions supports the conclusion that evaporation, along with weathering, are the main driving processes. Besides climate effects that result in the decrease of annual precipitation and the increase of evaporation, water consumption for domestic purposes (household and agriculture) aggravates the rise of the lakes’ salinity.

Published: May 2019

The complex water regimes and fragile ecological systems in Dongting Lake and Poyang Lake, located in the middle reach of the Yangtze River, have been significantly affected by regional climate change and anthropogenic activities. The hydrological data from the outlets of Dongting Lake (Chenglingji station) during 1955–2016 and Poyang Lake (Hukou station) during 1953–2014 were divided into two periods: the pre-impact period and the post-impact period. Four statistical tests were used to identify the change years: 1979 at Chenglingji and 2003 at Hukou. The indicators of hydrologic alteration and range of variability approach were used to assess alterations in water level regimes. Results show that the severely altered indicators were January water level at both lake outlets, and 1-, 3-, 7- and 30-day minimum water level at Chenglingji, with the degree of hydrological alteration being larger than 85%. The overall degrees of hydrological alteration at Chenglingji and Hukou were 52.6% and 38.2%, respectively, indicating that water level regimes experienced moderate alteration and low alteration or that ecosystems were at moderate risk and low risk, respectively. Changes in water level regimes were jointly affected by climate change and anthropogenic activities. Water level regimes at Dongting Lake outlet were mainly affected by increased rainfall and dam regulation. Decreased rainfall, dam regulation, and sediment erosion and deposition were the main impact factors of water level regimes at Poyang Lake outlet. These changes in water level regimes have greatly influenced both aquatic and terrestrial ecosystems, especially for fish and vegetation communities. This study is beneficial for water resource management and ecosystems protection under regional changes.
The Development and Application of the Urban Flood Risk Assessment Model for Reflecting upon Urban Planning Elements
Authors: Park Kiyong , Lee Man-Hyung
Published: May 2019

As a city develops and expands, it is likely confronted with a variety of environmental problems. Although the impact of climate change on people has continuously increased in the past, great numbers of natural disasters in urban areas have become varied in terms of form. Among these urban disasters, urban flooding is the most frequent type, and this study focuses on urban flooding. In cities, the population and major facilities are concentrated, and to examine flooding issues in these urban areas, different levels of flooding risk are classified on 100 m × 100 m geographic grids to maximize the spatial efficiency during the flooding events and to minimize the following flooding damage. In this analysis, vulnerability and exposure tests are adopted to analyze urban flooding risks. The first method is based on land-use planning, and the building-to-land ratio. Using fuzzy approaches, the tests focus on risks. However, the latter method using the HEC-Ras model examines factors such as topology and precipitation volume. By mapping the classification of land-use and flooding, the risk of urban flooding is evaluated by grade-scales: green, yellow, orange, and red zones. There are two key findings and theoretical contributions of this study. First, the areas with a high flood risk are mainly restricted to central commercial areas where the main urban functions are concentrated. Additionally, the development density and urbanization are relatively high in these areas, in addition to the old center of urban areas. In the case of Changwon City, Euichang-gu and Seongsan-gu have increased the flood risk because of the high property value of commercial areas and high building density in these regions. Thus, land-use planning of these districts should be designed to reflect upon the different levels of flood risks, in addition to the preparation of anti-disaster facilities to mitigate flood damages in high flood risk areas. Urban flood risk analysis for individual land use districts would facilitate urban planners and managers to prioritize the areas with a high flood risk and to prepare responding preventive measures for more efficient flood management.

Published: May 2019

It is not clear how projected climate change will impact the hydrological functioning of complex catchments that have significant karst characteristics. Therefore, in this paper we focused on the investigation of the low- and high-flow characteristics of the karst Ljubljanica River catchment. One smaller (51 km2) and one larger (1135 km2) catchment were selected in order to investigate the projected climate change impact on the hydrological conditions. For the investigation of the hydrological situation in the future, we used a lumped conceptual hydrological model. The model was calibrated using past measured daily data. Using the calibrated model, we investigated the impact of five different climate models outputs for the moderately optimistic scenario (RCP4.5). We investigated the situation in next 30-years periods: 2011–2040, 2041–2070, and 2071–2100. Several low and high-flow indices were calculated and compared. The results indicate that a summer precipitation decrease (i.e., 2011–2070) could lead to lower low-flow values for the investigated areas, which could increase the vulnerability of karst areas. Thus, additional focus should be given to water resource management in karst areas. On the other hand, mean flow could increase in the future. The same also applies for the high-flows where flood frequency analysis results indicate that a climate adaptation factor could be used for the hydrotechnical engineering design. However, differences among investigated models are large and show large variability among investigated cases.

Studying contemporary and subfossil Cladocera (Crustacea) communities, we explored the effect of top-down stressors on the cladoceran communities; we are also interested in the coherence of the contemporary and subfossil communities. The studied Cibakháza oxbow lake is in E Hungary, on the left-floodplain of the River Tisza; it is a large, long, and shallow oxbow lake. Three areas of the oxbow lake were distinguished based on the strength of top-down stress: protected area with low top-down stress, biomanipulated area with high top-down stress, and recreational area with moderate top-down stress. Altogether, we identified 28 taxa in the contemporary and subfossil communities in the oxbow lake. We found that the species number of the contemporary Cladocera communities was lower (protected area: 13; biomanipulated area: 9, and recreational area: 14) than in the subfossil communities (protected area: 20; biomanipulated area: 16, and recreational area: 14). Among the environmental variables, we observed differences between the protected and biomanipulated area, while the recreational area showed a transition. Species number, abundances, and Simpson diversity also showed the effect of the fish introduction. There were no differences in beta-diversity among the contemporary and subfossil Cladocera community. The non-metric multidimensional scaling (NMDS) ordination showed that the biomanipulated area in the case of the contemporary communities was separated from the other areas, while in the case of the subfossil communities, there was no separation according to top-down stress. Our results showed that the number of species of contemporary Cladocera communities was lower in each area (3–10; 3–9; 5–9) compared to the subfossil communities (6–17; 7–12; 8–12). However, the highest abundances were found in the biomanipulated area due to the appearance of small-sized Cladocera species. Our findings suggest that the effect of a short-time fish introduction is restorable when the oxbow lake has a protected part.

The major concern of the present research is degradation of
hazardous and stable Indigo dye used in industrial denim dying process. For
this purpose, a heterogeneous photocatalysis process was carried out to treat
aqueous solution of Indigo dye using pure titanium dioxide (TiO2) in
a batch reactor system under ultraviolet A (UVA) light for 210 min. In the
study, individual and synergistic effects of factors such as TiO2
dosage, pH, and initial dye concentration were scrutinized. Moreover, Taguchi
statistical method was performed to optimize influential parameters. The
results obtained from the study that TiO2 concentration had the most
effective factor on the Indigo dye degradation. The optimal conditions for dye
removal were A (pH) at level 2 (4), B (initial dye concentration) at level 1
(10 mg/L) and C (TiO2 concentration) at level 4 (1.5 g/L). The
results presented that the theoretically predicted value for degradation
efficiency (100%) was confirmed by the experimental value (100%).

Sığır, Keçi ve Koyunlarda mikroRNA’ların (miRNA) Meme Bezi Gelişimi ve Süt Üretimine Etkisi
Authors: DİNÇEL Deniz , ARDIÇLI Sena , ŞAMLI Hale , BALCI Faruk
Published: May 2019

Meme bezi (MB) gerek yeni doğanlara gerekse insan tüketimine süt üretimiyle önemli fonksiyona sahip olan ve ruminantlarda yavru doğumundan sonra büyüyüp gelişen kompleks bir organdır. MB’nin gelişimi ile sütün sentez ve salgılanması ise laktasyon süreci ile ilişkilidir. MB’nin verimi; beslenme, genetik, ırk ve epigenetik faktörlerin etkisi altındadır. Epigenetik faktörlerin başında gelen mikroRNA’lar (miRNA) ortalama 22 nükleotit (19-24 nt) uzunluğunda, kodlamayan RNA molekülleridir. Hücre çoğalması, farklılaşması ve apopitoz gibi önemli biyolojik süreçlerde rol oynayan miRNA’lar post transkripsiyonel regülatör olarak gen ekspresyonunda görev almaktadır. Karsinogenezden embriyogeneze kadar pek çok alanda yoğun olarak çalışılan miRNA’lar sığır, keçi ve koyun türünde sırasıyla; 1045, 436 ve 153 (olgun) adet tanımlanmıştır. Tanımlanmış miRNA’lar içerisinde kolostrumda 230, sütte ise 213 miRNA tipi tespit edilmiştir. Ayrıca kuru dönemde ve laktasyonun pik evresinde miRNA tipleri ve ekspresyon seviyelerinin farklılık gösterdiği belirlenmiştir. Bir başka çalışmada, sütte tespit edilen miRNA’ların miktar olarak kan serumundan iki kat daha fazla olduğu ve serumdan farklı 47 tip miRNA içerdiği görülürken; MB’nin kendine özgü miRNA’lar sentezlediği sonucuna varılmıştır. Ancak miRNA’ların meme bezi gelişimi ve laktasyon regülasyonundaki spesifik fonksiyonuna ilişkin bilgiler kısıtlıdır. Bu nedenle, miRNA’ların laktogenez mekanizmalarına olan etkilerinin aydınlatılmasına ve laktasyon süt verim ile bileşimine olan etkisinin anlaşılmasına yönelik moleküler çalışmalara ihtiyaç vardır. Bu derlemede çiftlik hayvanlarında miRNA’ların MB gelişimi ve süt üretimine olan etkilerine yönelik güncel bilgiler ve gelecekteki olası çıkarımlar üzerine odaklanılmıştır.

The aim of this
study is to perform phylogenetic grouping, to detect the virulence associated
genes in Escherichia coli strains
recovered from the urinary tract infections of dogs and cats, and to determine
the antibiotic susceptibility profiles, as well. The urine samples from the
animals showing clinical signs of urinary tract infection examined for the
occurrence of E. coli. Phylogenetic
classification of the isolates was performed according to the existence of chuA, yjaA and TSPE4.C2 genes. The isolates were also examined for the
presence of uropathogenecity-associated genes, such as, fimH, sfa1, iut, fyu, hly,
cnf-1, papG and for the diversity of
the papG allelles. Finally, the
antimicrobial susceptibility profiles were examined. E. coli was isolated from 11 (6.08%) of 181 samples. Two isolates
belonged to group A-2, while the remaining isolates belonged to group B-2. hylA was detected in 2 (25%); sfa1, cnf1, papG and papGIII were detected in 3 (37.5%); iutA was detected in 4 (50%);  fyuA
was detected in 6 (75%); and fimH was
detected in all of the isolates. Most of the isolates were resistant to
ampicillin while one isolate also showed multidrug resistance. The isolation
rate of E. coli was low in this
study, however, we had a brief data about the phylo-groups and virulence
factors of canine and feline uropathogenic strains.

Antropojenik Etkiler İle Havanın Kirletilmesi ve İklim Değişikliği
Authors: BÜYÜKŞAHİN Ferhat
Published: May 2019

Atmosfer, canlı
varlıkların yaşaması için değişik oranlarda gazlar içermektedir. Bu oranların
değişmesi durumunda eko-sistem tehlike altına girmektedir. Güneş, dünyaya kısa
dalga radyasyon gönderirken dünya, güneşten gelen ışınları uzun dalga radyasyon
olarak tekrar uzaya yansıtmaktadır. Ancak atmosferde artış gösteren sera
gazları, dünyanın geri yansıttığı uzun dalga radyasyonların uzaya gitmesine
engel olmaktadır. Bu olumsuz durum nedeniyle, küresel ısınma oluşmakta ve
iklimsel değişikliklere varan sonuçlar meydana gelmektedir. İklim değişikliği
iki ana etkenle oluşmaktadır. Birincisi doğal yollarla oluşan iklim
değişikliğidir. Doğal yollarla; Dünya’nın yörüngesel hareketlerinde meydana
gelen kaymalar, yerküreyi oluşturan levhaların birbirlerini itmesi sonucu dağ
silsilelerinin ve yükseltilerin oluşumu, güneş lekelerinde artış azalış
neticesi oluşan enerji miktarı, yeryüzü hareketleri neticesi (volkan
patlamaları, depremler vb.) atmosferin bileşenlerinin oranlarında değişimlerin
oluşması ve bunların sonucunda iklimsel değişimler oluşmaktadır. İkincisi ise
antropejenik etkiler ile meydana gelen iklim değişikliğidir. Antropojenik
etkilerin ana kaynağını ise aşırı karbondioksit salınımı oluşturmaktadır.
Sanayi Devrimi ve insan nüfusunun artışı ile birlikte insana bağlı hava
kirliliği ve karbondioksit salınımı son üç yüz yılda çok üst seviyelere
çıkmıştır. Felaketlerle sonuçlanabilecek bu kötü gidişata dur denilmez ise
gelecek nesillere sürdürülebilir bir yaşam bırakılamayacağı kesindir. Bu
bağlamda dünya devletlerinin ve bireylerin üstlerine düşen sorumlulukları
yerine getirmesi gerekmektedir. Bu noktadan hareketle, yapılan bu araştırmada
ülkelerin etkilerinden daha çok antropojenik etkenler ile havanın
kirletilmesine neden olan unsurlara ve çözüm yollarına değinilmiştir.
Bireylerin bilinçlendirilmesine ve eğitilmesine yönelik öneriler üretilmiştir.
Azda olsa ülkelerin üzerlerine düşen sorumluluklara ve önerilere de
değinilmiştir. Araştırmanın kavramsal çerçevesini literatür taraması
oluşturmaktadır.
Ömer Seyfettin’in Hikâyelerinde Savaşçı Arketipi
Authors: AL Hasan İlkay
Published: May 2019

ÖzetEski Yunanca olan arketip
sözcüğü Türkçe’de ilk imge, ilk örnek gibi anlamlara gelir. Arketipler,
insanlığın ortak mirasıdır. Sanat eserlerinde arketiplerin yer alması,
sanatçının ve eserin evrensele ulaşmasında katkı sağlar. Farklı kültürlerden ve
milletlerden insanların ortak paydasını teşkil eden arketipler, sanatçı ve
muhatapları için ortak dil olma özelliği taşır. Arketip olarak tanımlanan ortak
semboller ve figürler kolektif bilinçdışı aracılığıyla sanat eserlerinde
canlanmaktadır. Arketipler, edebiyat bilimciler tarafından mitoloji, psikoloji,
antrolopoloji, dinler tarihi gibi farklı disiplinlerden elde edilen bilgilerden
hareketle edebî eserlerde arketipsel eleştiri metodu aracılığıyla tespit
edilebilmektedir. Bu metot, yirminci yüzyıl itibariyle, modern
psikolojinin temsilcilerinden olan Carl G. Jung’un kolektif bilinçdışını
kavramını ortaya koyması sonucu ortaya çıkmıştır. Edebî metinlerin tahlilinde kullanılan arketipsel eleştiri metodu,
eserden hareketle eseri tahlil etme amacı taşır. Bu durum, arketipsel eleştiri
metodu aracılığıyla yapılan edebî eser incelemelerinin estetik değeri
yansıtmada başarılı olduğunu gösterir. Bu arketipik benlik yapılarından biri de
savaşçı arketipidir.
Boşanmanın psiko-sosyal sebepleri üzerine bir değerlendirme
Authors: DUMAN Nesrin
Published: May 2019

Evlilik kadar eski bir
kurum olan boşanma eşlerin, birlikteliklerinden psikolojik olarak doyum
sağlamadıkları, karşılıklı beklenti ve gereksinimlerini karşılayamadıkları
evliliklerine yasal olarak son vermeleridir. Büyük mutluluklar, hayaller ve geleceğe
yönelik planlar ile başlayan evlilik süreci, hem ülkemizde hem de dünya
genelinde artan bir şekilde pek çok
insan için boşanma ile nihayete ermektedir. Aile ve evlilik müessesesinin
dağılmasına yol açan ve önemli psiko-sosyal durumların doğmasına neden olan
boşanma; tüm boyutlarıyla ve nedenleriyle incelenmesi gereken bir olgudur. Bu çalışmada evlilik ve boşanma
sürecinin incelenmesi, Türkiye’de ve dünyada artan boşanma rakamlarına ilişkin
psiko-sosyal bir değerlendirme yapılması amaçlanmıştır. Bu amaç doğrultusunda
günümüz dünyasındaki sosyal, kültürel, teknolojik değişimlerin bireylerin
kişilik yapılanmaları, yaşamları, kişiler arası ilişkileri, gelecek
beklentileri, evliliğe bakış açıları, evlilik ve boşanma süreci üzerine
etkilerinin neler olduğu değerlendirilmiş; evlilik kurumu, kişileri evlenmeye
yönelten nedenler, eş seçimi, evliliğin başlaması ve sürdürülmesi, boşanma
süreci psiko-sosyal açıdan incelenmiştir.

Bu çalışmada toplumsal
cinsiyetin yaratılmasında ve sürdürülebilir kılınmasında dolayısıyla ataerkil
toplum düzeninin devamının sağlanmasında, ekonomi, eğitim, siyaset, medya,
hukuk ve din gibi seçilmiş bazı temel sosyal kurumların etkileri makro
çerçevede incelenmektedir. Kısaca, çalışmada insan olarak “kadın” konusu her
yönüyle olmasa da bazı temel yönlerden irdelenirken, cinsiyet ayrımcılığının
temel kaynağı olarak toplumsal cinsiyet anlayışının bu ayrımcılıktaki etkisi ve
kurumların bu ayrımcılıktaki rolleri ortaya konulmaya çalışılmıştır.
Doğrudan Yabancı Yatırımları Etkileyen Faktörlerin Çok Değişkenli İstatistiksel Yöntemler ile İncelenmesi

Published: May 2019

Yabancı
yatırımlar, doğrudan ve dolaylı yabancı yatırımlar olmak üzere iki kısımda
incelenmektedir. Dolaylı yabancı yatırımlar, bir ülkeden başka bir ülkeye olan
sıcak para ya da portföy yatırımları olarak ifade edilirken; doğrudan yabancı
yatırımlar, uluslararası yatırımcıların bir ülkeye fabrika gibi üretim
tesisleri kurarak, şube açarak, taşınmaz edinerek veya var olan bir şirketi
tamamen ya da kısmen satın alarak yaptıkları yatırımlardır. Küreselleşmenin
etkisi ile ülkeler arasında bilgi, hizmet ve sermaye hareketleri hız kazanmış
ve bunun bir sonucu olarak da ülkelerin büyüme ve kalkınma süreçlerinde
doğrudan yabancı yatırımların etkisi ön plana çıkmıştır.  Doğrudan yabancı yatırımlar, yatırım yapılan
ülkeye yeni teknoloji getiren, sosyal ve ekonomik  fayda sağlayan kalıcı yatırımlardır. Bu
çalışmada, literatürde doğrudan yabancı yatırımlar üzerinde etkisi olduğu
vurgulanan değişkenler ekonometrik bir bakış açısıyla değerlendirilmek yerine
çok değişkenli istatistiksel yöntemler ile değerlendirilmiştir. Dünya Bankası
2014 yılı verilerinden hareketle OECD, Ortadoğu ve Latin Amerika ülkeleri
incelemeye alınmıştır. Çalışmanın
ilk aşamasında birimler değişkenler olarak alınmış ve doğrudan yabancı sermaye
yatırımlarını etkileyen çeşitli makro ekonomik, sosyal ve kurumsal dinamikler
arasındaki ilişki dikkate alınarak Ortadoğu, OECD ve Latin Amerika ülkelerinden
oluşan bu üç farklı ülke grubu, uzaklıklar matrisine dayanan bir boyut
indirgeme tekniği olan çok boyutlu ölçekleme ile kıyaslanmıştır. İkinci
aşamada ise ilgilenilen ülke grupları içerisindeki homojen ülke grupları,
kümeleme analizi ile belirlenmiş ve bulgular değerlendirilmiştir. Ortadoğu ve
Latin Amerika ülkelerinde doğrudan yabancı yatırımları etkileyen değişkenlerin
makro ekonomik değişkenler olmadığı, politik istikrar, yolsuzluk düzeyi ve
demokrasi gibi değişkenlerin belirleyici olduğu görülmüştür. Türkiye’nin
doğrudan yabancı yatırımlar açısından Ortadoğu ülkelerinden Ürdün, Lübnan,
İsrail ve Tunus ile benzer yapıda olduğu; OECD ülkelerinden ise Kore ile
doğrudan yabancı yatırımlar ve ilişkili faktörler bakımından benzer yapı
sergilediği saptanmıştır.
Yetiştirme Yurdunda Kalmış Bireylerde Yalnızlık ve Sosyal Bütünleşme Düzeylerinin Bazı Sosyo-Demografik Özellikler Bakımından İncelenmesi
Authors: YILDIZ Murat , KILIÇ Mehmet Emin
Published: May 2019

Bu çalışmanın amacı, çocukluk ve/veya
ergenlik döneminde yetiştirme yurdunda kalmış bireylerde yalnızlık ile sosyal
bütünleşme düzeyleri arasındaki ilişkiyi saptamaktır. Bununla birlikte bu
değişkenleri bazı sosyo-demografik özellikler çerçevesinde incelemektir. Araştırma-nın
örneklemi, hayatlarının bir döneminde yetiştirme yurdunda kaldıktan sonra ayrılmış
olan 158 katılımcıdan oluşmaktadır. Bu bireyler, Sivas, Malatya ve Gaziantep
illerinde benzer hayat hikayesi olanların dayanışma amaçlı kurdukları 3
derneğin üyesidirler. Örneklemin
%82,9’unu (n=131) erkekler, %17,1'ini (n=27) kadınlar oluşturmaktadır. Veri
toplama aracı olarak Kişisel Bilgi Formunu da içeren, Russel, Peplau ve
Ferguson (1978) tarafından geliştirilmiş olan ve Demir (1989) tarafından da Türkçeye
uyarlanarak güvenirlik ve geçerlik çalışmaları yapılmış olan UCLA Yalnızlık
Ölçeği ile Şimşek ve Şimşek (2013) tarafından beşli Likert modelinde
geliştirilen Sosyal Bütünleşme Ölçeği’nden oluşan bir form kullanılmıştır.
Çalışmada elde edilen bulgularda, yalnızlık ile sosyal bütünleşme arasında
negatif yönde anlamlı bir ilişkinin olduğu, yalnızlık arttıkça sosyal
bütünleşmenin azaldığı saptanmıştır. Ayrıca yalnızlık değişkeni açısından
cinsiyet, eğitim düzeyi ve medeni durum grupları anlamlı düzeyde
farklılaştıkları; sosyal bütünleşme bakımından erkeklerle kadınlar ve medeni
durum grupları arasındaki farklar anlamlılık düzeyine ulaştıkları saptanmıştır.
Buna karşın yaş grupları ile yetiştirme yurtlarında kalış sürelerine göre oluşturulmuş
gruplar arasında yalnızlık ve sosyal bütünleşme değişkenleri açısından
farkların anlamlı olmadığı tespit edilmiştir. Yine eğitim düzeylerine göre
sınıflandırılmış grupların sosyal bütünleşme ortalama puanları bakımından farklılaşmanın
anlamlılık düzeyine ulaşmadığı saptanmıştır.
