Havayolu şirketlerinin kriz döneminde uygulaması beklenen stratejileri

Taşımacılık sektörü günümüzün en gözde meslek ve sektörlerinden biri olmakla birlikte gelecekte de en büyük sektörlerden biri olacağı açıktır. Gerek istihdamı gerekse bu alanda çok büyük bir açıklığın olması firmaları ciddi derecede cezbediyor. Sektörün bu derece popüler olmasının temel nedeni ise çağımızın yaşadığı küreselleşme. Fakat küreselleşme her ne kadar özellikle taşımacılık alanında hiç beklenmeyen bir çığır açsa da firmaların korkulu rüyası rekabeti de artırmıştır. Taşımacılık sektörü karada her ne kadar artmış ve faaliyet alanını genişletmiş olsa da hava lojistiği günümüzün en büyük trendi olmuştur. Gelişen teknoloji ve küreselleşme ile firmalar birbirlerini takip etme ve geçme de en uç noktaları zorlamaktadır. Havacılık, çok fazla rekabetin olduğu ve hızlı değişiklerin yoğun bir şekilde yaşandığı sektörlerden biri haline gelmiştir. Bu durum havayolu şirketlerini müşterilerinin ihtiyaçlarını ve isteklerini daha iyi anlamaya yönlendirmektedir. Günümüz işletmeleri iş hayatlarında bazen iniş-çıkışlar yaşarlar. İşletmelerin hem çalışanlarına hem müşterilerine hem de topluma karşı toplumsal sorumlulukları vardır. Bu nedenle firmalar kendi ve markalarının kimliğini ve geliştireceği pazarlama stratejilerini iyi planlamalı ve ona göre hareket etmelidir. Birçok işletmenin, kurumsal itibar ve kurum imajlarını yükseltmek için çeşitli çalışmalarda bulundukları ve para harcadıkları bilinen bir gerçektir. Kriz anında etkin bir iletişim kurmak ve krizi en az hasarla atlatmak hatta krizi bir fırsat olarak görüp değerlendirmek ve bütün bunlar için bir ilk adım olarak etraflı ve etkili bir kriz yönetimi planına sahip olmak açısından çok önemlidir. Başka bir deyişle, işletmeler kriz öncesinde stratejik planlar yapmalı, muhtelif zamanlarda bunu test etmeli ve aksaklıkları bulmaya ve çözmeye çalışmalıdır.

Moderating effects of workforce diversity on the relationship between entrepreneurial orientation and organizational performance

In today's global environment capital resources are interconnected throughout the world. Resources are moving freely from one part of the world to another, which provide organizations with ample capital resources and diverse human capital. The need of diversity increased after the Industrial Revolution and the formation of trade and employee unions within EU countries. It is not uncommon for a multinational company to have its finance department headed by American, recruitment department headed by Asian and operations run by Indian employees. The diverse workforce or workforce diversity is a two-sided sword, it has some negative, and some positive aspects attached to it. The aim of this Thesis is to critically review the moderating effect of diverse workforce on the relationship between entrepreneurial orientation and performance of an organization. Great work have been done on the defining different aspects of diversity and managing the diverse workforce but very little work is found that truly gauge the impact of diversity in nurturing entrepreneurial traits in organization that are connect to the better performance of an organization. Paper discusses moderating effect of diversity on all three aspects of Entrepreneurial orientation i.e. Innovation, Proactiveness and Risk-taking.

Kişilik, örgütsel güven ve bağlılığın duygusal emeğe etkileri ile işten ayrılma niyeti arasındaki ilişkinin belirlenmesine yönelik bir araştırma

Çalışanların hizmet gösterimleri sırasında, müşteriler ile iletişim halindeyken, belirli kurallar çerçevesinde harcamış oldukları çaba olarak bilinen duygusal emek, müşteriler veya hizmet alan kişiler ile yüzyüze veya sözlü iletişim gerektiren işlerde sergilenmektedir. Eğitim sektöründe de duygusal emek gösterilmektedir. Bu çalışmanın amacı, kişilik, örgütsel güven ve bağlılığın belirleyici olarak duygusal emeğin öncüsü olup olmadığının belirlenmesi ve duygusal emeğin işten ayrılma niyeti üzerinde tükenmişliğin aracılık etkisinin belirlenmesidir. Bu amaçla literatür çalışması yapılmış olup, hipotezler geliştirilmiştir ve test edilmiştir. Araştırmanın evrenini 2016 yılı Yüksek Öğretim Kurumu verilerine göre İstanbul ilinde bulunan vakıf üniversitelerindeki 5205 akademik personel oluşturmuş olup, örneklem olarak 540 akademik personel ele alınmıştır. Örnekleme 19 sorudan oluşan Duygusal Emek Ölçeği, 20 sorudan oluşan Kişilik Ölçeği, 18 sorudan oluşan Örgütsel Bağlılık Ölçeği, 22 sorudan oluşan Örgütsel Güven Ölçeği, 22 sorudan oluşan Tükenmişlik ölçeği, 4 sorudan oluşan İşten Ayrılma Niyeti Ölçeği ve demografik soruları içeren ve 7 bölümden oluşan 110 soru yöneltilmiştir. Araştırmada elde edilen veriler, SPSS (Statistical Package for Social Sciences) Windows 22.0 programı kullanılarak analiz edilmiş ve t testi, tek yönlü anova testi post-hoc analizi olarak scheffe testine tabi tutulmuştur. Değişkenler arasında pearson korelasyon ve regresyon analizi ve ayrıca hiyerarşik regresyon analizi ve sobel testi uygulanmıştır. Yapılan çalışmanın analizine göre; sorumluluk, dışa dönüklük ve duygusal denge kişilik özelliklerinin ve duygusal bağlılığın, devam bağlılığının, yöneticiye, örgüte ve çalışma arkadaşlarına güvenin duygusal emek üzerinde etkisi olduğu sonucuna varılmıştır. Ayrıca duygusal emek ile işten ayrılma niyeti arasında tükenmişliğin ara değişken olduğu, yüzeysel duygusal emek, derinlemesine duygusal emek ile işten ayrılma niyeti arasında tükenmişliğin kısmi ara değişken olduğu sonucuna ulaşılmıştır. Eğitim sektöründe duygusal emeğin incelenerek yukarıda bahsedilen değişkenlerle ilişkisi konusunda yapılan bu çalışmanın, alanla ilgilenen araştırmacılara faydalı olacağı düşünülmektedir.

Smart cities, smarter management developing a smart framework for smart city projects management in Europe

The smart cities concept is currently considered one of the "hottest topics" in urban development, especially in Europe. Cities around the globe have been promoting and supporting smart city projects, reflecting the belief that integrating technology and infrastructure can enhance cities' livability, sustainability, services and competitiveness. Though a lot of research on the topic has been done, there are still limited insights into the managerial angle. This thesis research is thus undertaken to fill this gap by exploring the smart city through a lens of management in order to develop a deeper understanding of smart city projects. Also, it focuses more on the role of smart management in the smart city project success by viewing the smart city as a unique complex project and identifying smart city projects success practices and challenges. Through a quantitative correlational study, the thesis investigates the relationship between smart project management practices and smart city project success in different smart city projects located in Europe. Based on the analysis, a conceptual framework was proposed setting out a holistic view of smart city projects management.

Örgütsel politika algısı ile örgütsel bağlılık ilişkisinde örgütsel güvenin aracılık rolünün belirlenmesine yönelik İstanbul'daki üniversitelerde bir araştırma

Bu çalışmanın amacı; örgütsel politika algısı ile örgütsel bağlılık ilişkisinde örgütsel güvenin aracılık rolünü ortaya çıkarmaktır. Bu bağlamda, örgütsel politika algısı ile örgütsel bağlılık ilişkisinde örgütsel güvenin belirleyici rolünü ortaya çıkararak, bu üç değişkenin birbirlerini nasıl etkilediğini belirlemek çalışmanın nihai hedefleri arasında yer almaktadır. Yükseköğretim kurumlarında görev alan akademisyenlerin, iş stresi, iş kaybı korkusu ve yükselme kaygısı gibi nedenlerle sübjektif değerlendirmelerde bulunmaları, yöneticilerine ve örgütlerine olan güvenlerinin kaybolmasına neden olurken politik tavırlarda bulunmalarına da zemin hazırlamaktadır. Bu durumda akademisyenlerin, kurum içerisinde çeşitli çıkar çatışmaları yaşamaları sebebiyle olduklarından farklı davranışlar sergilemeye ve bağlı bulundukları kurumu politikleştirmeye eğilim gösterecekleri gözlemlenmiştir. Dolayısıyla, akademisyenlerin örgütsel politika algılarının artış göstermesinin, onların örgüte güven duygusu geliştirme konusunda isteksiz tutumlar sergilemelerine sebep olduğu, aynı zamanda örgütsel bağlılıklarını da azalttığı tespit edilmiştir. Bu durum, çalışanın örgütüne geliştirdiği bağlılık duygusunun örgütsel politika algısından etkilendiğini ve güven duygusu sarsılan çalışanın sergilemiş olduğu tavırlara bağlı olarak bağlılık düzeyinin değişkenlik gösterdiğini ortaya çıkarmıştır. Çalışma kapsamında yükseköğretim kurumlarında çalışmakta olan toplamda 267 akademik personele ulaşılmıştır. Katılımcıların konu hakkındaki görüşlerini saptamak amacıyla düzenlenmiş olan anketin sonuçları SPSS programı ile analize tabi tutulmuştur. Araştırma sonucunda; akademisyenlerin örgütsel politika algılarının ve örgütsel güven düzeylerinin, örgütsel bağlılık düzeylerini etkileyen belirleyici değişkenler olduğu gözlemlenmiştir. Bu bağlamda yapılan analizlerin sonucunda söz konusu üç değişken arasında anlamlı ilişkiler olduğu tespit edilmiştir.

The impact of warehouse relocation on the supply chain department

The increase of imports and exports started in 2005 with a small decrease in 2009 and 2015. Since 2017, Turkey's foreign trade has risen again. Changes in the foreign trade environment have led to significant attention being focused on the logistics activities of global companies. Turkey's transportation and logistics sector is one of the fastest growing since 2002, with an average of 20% annual growth. Global operating companies have seen positive impacts over the last few years from foreign trade growth. In order to meet these positive impacts of growing trade, is it important that companies criticise and analyse all logistics activities and their warehouses. Businesses have also been investing in order to increase their warehousing quality. Since the supply chain is often called the beating heart of a company, this study attempts to find all effects of a warehouse relocation. The aim of this study is to analyse and gain specific information about warehouse management, relocation decisions, relocation processes, and all the related impacts on a company. In order to cover all these aims, the following research question was formulated: What are the impacts of relocating a warehouse for the supply chain department? This research question is answered with the help of a literature review and qualitative research. In depth interviews with the method of phenomenology were used to understand experiences of a focus group, with samples that contributed recently to a warehouse relocation. Based on research results, it can be concluded that relocation affects not only the supply chain department but the whole company. There are positive and negative impacts of relocating a warehouse. The positive impacts of relocation are fulfilling company expectations, redesigning the warehouse, an increase in employee confidence, improved policies and procedures, and financial benefits. The negative effects of relocation are the shutdown, time costs, communication, and financial impacts. This study also concludes that cohesion between warehouse and supply chain is needed to maximize the relocation process and that communication before and after relocation is not the same, as more meetings are necessary beforehand. Further, it can be concluded that common reasons for moving include growth and an increase in capacity or the end of a contract, and that a relocation process should proceed in phases. Finally, the most important disadvantage of relocation is extra effort and workforce, and the most important benefit is that relocation could lead to the realization of all expectations of the warehouse from a company. Based on this study, the following recommendations are given: (1) prepare a detailed plan that covers each step in the whole process; (2) do research for risk scenarios, in order to understand what could go wrong during the moving process; (3) motivate all employees who are going to realize the relocation, because their support makes the relocation process smoother; and (4) realize all the desired changes with the relocation, which could range from system changes to storage criteria. Keywords: Warehouse, supply chain, relocation impact, relocation process, logistics.

It factually supports the argument that communication is important and can positively impact the various stakeholders within and out of the organization. In determining this fact, a thorough review of the works of earlier writers in this domain was done, as well as related articles; reports and books were also consulted. Furthermore, data was also collected using depth interview from sampled organizations in Douala Cameroon and analysed which added more flesh to the fact that effective communication is a catalyst to productivity and growth. The internal and external environment of a firm was also discussed as well as the impact of absence in communication and the influence of communication on these surroundings in order to comprehend how managers should implement operational communication in organizations. Besides, this research goes ahead to highlight the importance of employee's satisfaction, with respect to them communicating effectively. It is observed that there is a considerable level of effective communication in a majority of the sampled organizations, resulting from employees' satisfaction and moderate rate of motivation from the employers. Upon the interview's data collection results, it becomes clear that organizations in Douala Cameroon have developed their efficiency and progression through operational communication. Nevertheless, it appears that more efforts should be done towards employees by employers in organizations, so as to encourage, motivates and rewards employees, thus implementing beneficiary practices towards the organization for its growth.
