    Due to the dynamic nature of the urban development in developing countries in parallel to rapidly changing economic, social and technological environments, decisions based on master plans do usually fail. Therefore, spatial transformation is the number one prerequisite to create more livable cities in countries where land use and location decisions do greatly divert from master plans that ill-fully represent the nature of urban development in rapidly changing environment. It is very unfortunate that like many developing countries, central government as well as local governments in Turkey have adopted this approach which is totally inappropriate to their changing environment due to rapid urbanization. In middle and low income economies, urbanization has increased by an average of 3.5 and 3.7% per annum, respectively, compared with an average of 1.5% per annum in the industrialized countries (the rate in Turkey was 4.35% from 1965 to 1985). The percent of urban population in the largest city in Turkey, Istanbul, was 24% in 1980 compared to 18% in 1960. The population of Istanbul was 11.2 million in 2000 compared to 11.3 million of Paris and 11.1 million of Osaka, Kobe (World Development Report by World Bank, 1984). In the periphery of the metropolitan city of Istanbul, there are numerous neighborhoods and urban centers hat need spatial transformation or renewal for the betterment of urban space. Renewal was defined as clearance and redevelopment until the mid-1960s. This approach for the urban betterment was changed in the 1970s by establishing legal ground via improvement and development plans. In contrast to this, in parallel to the radical changes in economic policies in the 1980s, renewal policy for the problematic locations in large urban areas were again equaled regeneration, and spatial transformations were made for the capitalization of global interests in the name of urban rent by transformation projects (Dündar, 2001). The former— improvement and development plans— failed due to the reason said in the beginning. The latter— transformation projects— have found limited application (Portakal Çiçeði, Dikmen Vadisi, Zafer Plaza transformation projects and some others) due to two great limitations: finances and public acceptance towards transformation projects. To overcome these obstacles in general, some approaches are developed, such as ÝHT-ÝHTr-Real-estate planning tools, master plans for earthquakes and natural disasters (Istanbul Metropolitan City), KED Model (Çelikhan et al., 2004). However, these approaches have not found widespread application yet due to necessary legal changes they require and most importantly the finances needed for the transformations desired in urban areas. Under the economic and social conditions in developing countries, what expected from ideal transformation approaches are to create financial tools during the process and to offer the urban rent to land owners primarily in order to speed up the transformation process towards the desired direction by creating voluntarily participation at the utmost level and to reduce the legal problems due to the introduction of new developments and land use planned by the transformation projects to be applied. This study is originated from the idea that large urban developments attract new land uses and users to their proximity or repel current land uses and users around them. This process can be seen as a “voluntarily transformation” process. Since large shopping centers or malls are built in almost every largely populated urban area all over the world in the last 20-30 years due to new shopping habits and global capital investments, we studied the effects of large shopping malls on land use in their proximity as being large developments they create urban transformation process in their proximity, as a case study in Istanbul, Turkey. To support our approach, Dennis at al. (2002) interestingly reported in their study in Northern London that the fist step in urban renovation is to renovate retail shopping and shopping centers. In this context, we performed user surveys in residential and commercial areas as well as at real estate agents in the proximity two large shopping centers; namely, Akmerkez (Etiler, Beþiktaþ) and Tepe-Nautilus (Acýbadem, Kadýköy) in Istanbul. In addition, in the study areas the data on land use changes provided by State Statistics Institute of Turkey have been examined. It is concluded the shopping centers stimulated urban transformation on real estates in their close proximity, and in time they created transformations from residential to commercial within their primary influence boundaries, and beyond those up to a certain distance they became an attractive zone for residential use.

    Water Stress Hinders In Vitro Regeneration of Plants

    Plants could be propagated vegetatively via small parts of living tissue called as ‘explant’ on growth mediums under sterile conditions. Plant cell has the ability of forming whole fertile plant which is called \u27totipotency\u27, under in vitro culture conditions. High-frequency shoot regeneration is one of the main aims of in vitro culture and it is a prerequisite to guarantee the success in transformation studies and in clonal propagation of plants. It is well known that growth regulators in culture medium and the type of explant affect in vitro regeneration frequency significantly. In this chapter, the importance of tissue water content on in vitro culture response is discussed. Increasing water content of the explant before culture initiation gives rise to increased regeneration capacity. On the other hand, increasing the tissue’s osmotic pressure enables the explant to intake water, all solutes and growth regulators from the growth medium which results in high-frequency shoot regeneration. However, tissues with lack of water are usually not successful in regenerating a satisfactory amount of shoots. The effect of water deficiency on explant’s regeneration capacity and the methods to overcome this problem are discussed in this chapter

    Multicriteria sustainability evaluation of transport networks for selected European countries

    As an essential economic activity, transportation has complex interactions with the environment and society. Since the concept of sustainable development has become one of the top priorities for nations, there has been a growing interest in evaluating the performance of transport systems with respect to sustainability issues. The main purpose of this study is to introduce a decision making framework to assess the sustainability of the transport networks in a multidimensional setting and a technique to identify non-compromise alternatives. We also propose an elucidation technique to identify according to which criteria a system needs to be improved and how much improvement is required to attain a certain level of sustainability. The proposed methods are applied to a set of selected European countries within a case study

    Attention deficit hyperactivity symptoms predict problematic mobile phone use

    Attention-deficit-hyperactivity disorder (ADHD) is the most commonly diagnosed childhood disorder characterised by inattention, hyperactivity/impulsivity, or both. Some of the key traits of ADHD have previously been linked to addictive and problematic behaviours. The aim of the present study was to examine the relationship between problematic mobile phone use, smartphone addiction risk and ADHD symptoms in an adult population. A sample of 273 healthy adult volunteers completed the Adult ADHD Self-Report Scale (ASRS), the Mobile Phone Problem Usage Scale (MPPUS), and the Smartphone Addiction Scale (SAS). A significant positive correlation was found between the ASRS and both scales. More specifically, inattention symptoms and age predicted smartphone addiction risk and problematic mobile phone use. Our results suggest that there is a positive relationship between ADHD traits and problematic mobile phone use. In particular, younger adults with higher level of inattention symptoms could be at higher risk of developing smartphone addiction. The implication of our findings for theoretical frameworks of problematic mobile phone use and clinical practice are discussed

    Background: There has been a trend in the past five years in Jordan for ophthalmic anticholinergic preparations to be misused or abused. This is done mainly to experience mental altering effects such as mood changes, euphoria or hallucinations. Such products are mostly obtained from community pharmacies without a prescription. Objectives: This study aimed to observe the requests of ophthalmic preparations in community pharmacies in Amman, Jordan, and evaluating the most popular and frequently requested ophthalmic drops suspected of abuse. Also, it aimed to describe the current methods that Jordanian community pharmacists use to manage such requests. Methods: A prospective cross-sectional observational study was conducted between November 2016 and January 2017 at sixteen different community pharmacies in Amman. All ophthalmic products requested were observed during this period. Results: A total of 140 ophthalmic product requests for 130 customers were observed. Dry eye was the most common complaint for which the customer requested the medication (n = 30, 23.1%) and direct self-medication (ie-requesting the product by name), was the most frequent method of purchase (n = 63, 48.5%). In 19 cases (14.6%), product requests were suspected to be for non-medical (ie-abuse) purposes. Most of the suspected cases were for Pentolate® (n = 11, 57.9%), whereas 7 were for Prisoline® (36.8%) and 1 for Naphcon-A® (5.3%). The majority of observed cases were for products requested without a prescription (n = 16, 84.2%), and in 12 cases out of which, sale was refused (63.2%). Conclusion: More effort and enforcement of pharmacy regulation for safe dispensing is needed to reduce the abuse of ophthalmic products. Educating pharmacists and ophthalmologists would help raise awareness and control the type of drug abuse. © 2019 Elsevier Inc

    An investigation into problematic smartphone use: the role of narcissism, anxiety, and personality factors

    Get PDF
    Background and aims: Over the last decade, worldwide smartphone usage has greatly increased. Alongside this growth, research on the influence of smartphones on human behavior has also increased. However, a growing number of studies have shown that excessive use of smartphones can lead to detrimental consequences in a minority of individuals. This study examines the psychological aspects of smartphone use particularly in relation to problematic use, narcissism, anxiety, and personality factors. Methods: A sample of 640 smartphone users ranging from 13 to 69 years of age (mean = 24.89 years, SD = 8.54) provided complete responses to an online survey including modified DSM-5 criteria of Internet Gaming Disorder to assess problematic smartphone use, the Spielberger State-Trait Anxiety Inventory, the Narcissistic Personality Inventory, and the Ten-Item Personality Inventory. Results: The results demonstrated significant relationships between problematic smartphone use and anxiety, conscientiousness, openness, emotional stability, the amount of time spent on smartphones, and age. The results also demonstrated that conscientiousness, emotional stability, and age were independent predictors of problematic smartphone use. Conclusion: The findings demonstrate that problematic smartphone use is associated with various personality factors and contributes to further understanding the psychology of smartphone behavior and associations with excessive use of smartphones
