Abstract

Purpose - The aim of this paper is to discuss the reasons behind the attractiveness of shopping malls for young consumers in Turkey and then to determine the attractiveness factors of malls for this segment from the consumer's perspective. Design/methodology/approach - The study was carried out through a survey of 621 young consumers (aged between 12-24) in three out-of-town selected shopping malls in Bursa, Turkey. For a general evaluation of the data, factor analysis is applied. It is considered as a valuable tool to reduce dimension and group different characteristics of young consumer's mall usage. Findings - The study reveals five mall attractiveness factors from the young Turkish consumer's perspective: retail environment, comfort conditions, socializing in a secure environment, accessibility, leisure. The importance of all these factors for this segment are evaluated with a comparative analysis with the findings of many other studies, analyzing the similar issues in relation to different cultures. Research limitations/implications - The sampling frame for this research was limited to young consumers in Bursa, Turkey. Study findings, although interesting, are clearly not generalizable to all populations of young consumers or even all Turkish young consumers. Practical implications - Identifying mall attractiveness factors for young consumers gives a better understanding about patronage motives than when it is applied to the market as a whole. Originality/value - This is one of the first studies to provide an insight of mall attractiveness factors as identified by young Turkish consumers from the viewpoint of an urban studies researcher, rather than marketing researchers.

Abstract

Monosex populations can be a valuable management tool in culture of larger size largemouth bass (>400 g). In this study, we investigated the effective mode and duration of oestrogen and androgen administrations to produce monosex largemouth bass populations. The experiment consisted of nine treatments. In oral administration groups, we fed 40-day-old fry either 200 mg of an oestradiol-17β (E2) kg−1 diet or 60 mg of a 17α-methyltestosterone (MT) kg−1 diet for 30, 45 or 60 days. In bath treatments, we immersed fry in a 1 mg MT L−1 solution for 5 h a day on three or six occasions. For control treatment, we fed fry an ethanol-treated diet for 45 days. The frequency of females in the control group was 53.1%. Oral administration of E2 at all durations resulted in slight increases in the frequency of females (59.8–70.5%). Both modes of androgen administration at all durations were ineffective in altering phenotypic sex. The experimental results of our study indicated that male differentiation passed the point of being completely and functionally influenced by exogenous oestrogens, while female differentiation had already taken place and was no longer responsive to exogenous androgens in 40-day-old (33.5 mm) largemouth bass fry.

Abstract

We investigated the feminization of bluegill and black crappie by short periodic immersions in an aqueous estradiol-17β (E2) solution. Bluegill fry (13.8 mm) were immersed in a 1 mg L−1 E2 solution every 5 days on three occasions over an 11-day period. In the positive control treatment, the same cohort of fry was fed 200 mg kg−1 E2 diet for 45 days. Two different size (26.1 and 20.1 mm) but the same age (45 days old) black crappie fry were immersed in the same concentration of E2 solution for 5 h a day every 3–5 days on 10 occasions between 45 and 86 days post hatch. Both modes of E2 administration were effective to induce feminization in bluegill. Feeding fry E2 impregnated diet for 45 days yielded 99.3% female populations from a 38.8% female experimental population. Only three short-time E2 immersions of fry over a much shorter treatment period also produced 76.9% female populations. E2 immersions had no effect on sex ratios of larger black crappie fry and produced variable levels of feminization (60–82% female) in smaller black crappie fry. Results of the present study showed that feminization in both species can be achieved by periodic immersions of fry in a 1 mg L−1 E2 solution with no adverse effects on survival. Yet, further researches on timing and intensity of immersion treatments are still needed for optimization of the procedures. [ABSTRACT FROM AUTHOR]

Abstract

Kentsel Dayanıklılık kavramı literatürde genellikle bir sistemin iç ve dış değişim karşısında işlevlerini ve yapısını sürdürme yeteneği ve mevcut kaynakları ve becerileri yeni durumlara ve çalışma koşullarına uyarlama yeteneği olarak tanımlanmaktadır. Kentlerin tarihleri boyunca karşılaştıkları tüm yıkıcı de değiştirici etkilere karşı nasıl direnç gösterdikleri birçok araştırmanın konusu olmuştur. Tunis kentinin tarihi kent merkezinde (medina) yer alan tarihi çarşı bölgesi tarihi boyunca karşılaştığı sosyal, ekonomik ve kültürel değişim süreçlerine karşın günümüzde halen varlığını ve işlevini devam ettirmektedir. Tarihi kent merkezinin (medina) karşılaştığı savaşlar, krizler, pandemiler ve diğer tüm felaketler tarihi çarşı bölgesinin gelişiminde ve dönüşümünde belirleyici olmuştur. Ancak, bütün bu süreçlere ragmen, Çarşı bölgesi kurulduğu 7. Yüzyıldan bugüne kadar çağlar boyunca mekansal bütünlüğü ve morfolojik yapısını korumaya devam etmiştir. Bu çalışmanın amacı Tunis tarihi kent merkezinde (medina) yer alan çarşı bölgesinin dayanımının ardındaki nedenleri tartışmaktır. Bu tartışmanın yapılabilmesi için çalışma kapsamında kentsel dayanım kavramı araştırılmıştır. Bu kavrama ilişkin literatürde kabul gören temel göstergeler ortaya konmuştur. Bu göstergelerden çeşitlilik, bağlantı, modülerlik, fazlalık ve uyarlanabilirlik Tunis kentindeki çarşı bölgesinin dayanımını araştırmak için seçilmiştir. The concept of urban resilience is generally defined in the literature as the ability of a system to maintain its functions and structure in the face of internal and external changes, and the ability to adapt existing resources and skills to new situations and working conditions. How cities resisted against all the destructive and transformative effects that they encountered throughout their history has been the subject of many studies. The historical bazaar area, located in the Medina of Tunis city, still continues its existence and function today despite the social, economic and cultural change processes that it has encountered throughout its history. Wars, crises, pandemics and all other man-made and natural disasters faced by the Medina have been decisive in the development and transformation of the historical bazaar area. However, despite all these processes, the Bazaar region has continued to preserve its spatial integrity and morphological structure throughout the ages since the 7th century when it was founded. Here the question arises about how this city managed to keep its urban spatial and how it achieved the resilience and its self-organization? What are the main features behind it? The aim of this study is to discuss the reasons behind the resilience of the bazaar area in Tunis Medina. In order to make this discussion, the concept of urban resilience has been investigated within the scope of the study. Basic indicators accepted in the literature regarding this concept are presented. Among these indicators, diversity, connectivity, modularity, redundancy and adaptability were chosen to investigate the strength of the market area in Tunis city.

Abstract

The significance of urban development has been realized again while acute shocks and chronic stresses (earthquake or unemployment) affect cities in a negative way. Therefore, urban resilience becomes more important for economic, environmental, and social sustainability of the built environment. There is a wide range of approaches to resilience in the literature such as ecological, engineering, and adaptive systems. Unlike others, adaptive resilience establishes a co-evolutionary interaction between actors (existing building) and the system (external effects) that leads to a continual process on their adjustment. In relation to cities, built environment is also under a constant change. As the advent of new technology has changed buildings’ use, some of them have faced obsolescence in physical, economic, functional, technological, social, legal, and political ways. The importance of time-based design over form-based design thinking has come to the fore. However, existing obsolete buildings could gain new functions and contribute to urban resilience and sustainability through adaptive reuse method. The purpose of this study is to provide assessment criteria for existing buildings’ adaptive reuse potential in the context of resilient cities. Thus, the research incorporates Holling’s resilience cycle (1986) and Schmidt III et. al’ s building layers and time concept (2009) for resilient adaptive reuse strategies. Keywords: adaptive reuse, resilient cities, adaptive resilience, building layers, time-based design
