A lojalitásprogramok menedzselése (Managing of loyalty programs)

A lojalitásprogramok egyre népszerűbbek hazánkban is, ahogy a növekedési lehetőségek bezárultak, és a menedzserek figyelme a vevők és a piaci pozíciók megtartása felé fordult. A közelmúltban azonban számos nemzetközi példa mutatja, hogy egy ilyen program lehet sikertelen is, amely veszteséget termel, így vagy kivezetésre kényszerül, vagy a vállalat kénytelen átszabni. Tudatos tervezés és reális üzleti modell nélkül tehát nem feltétlenül térül meg az akár milliárdos nagyságrendű befektetés. Jelen cikk során a szerző kísérletet tett arra, hogy összegyűjtse azokat a döntési pontokat, amelyek hatással lehetnek a programok sikerére, és bemutassa a lehetséges választási alternatívák előnyeit, hátrányait. Konklúzióként három olyan elvet emelt ki, amelyek meghatározóak lehetnek. Eszerint a programoknak a vállalati stratégiába és folyamatokba történő integrációja, a megfelelő megtérülési indikátorok felállítása és azok szisztematikus nyomon követése, valamint a program megkülönböztető, többnyire emocionális és élményszerű jellege, amely kiemelkedő szerepet játszhat az eredményesség szempontjából. _____ As the opportunity of market growth seemed to be limited and managers started to pay more attention to customer retention and market defence, loyalty programs became more and more popular marketing tool in Hungary. Many international cases proved, however, that the implementation of this activity can also lead to failure realizing considerable losses and by necessity companies can end up or reposition the program. Without a deliberate design and realistic business model it is not easy to guarantee the return of investment that can be even billion in size. In the current article the author attempts to collect all the relevant issues that can have effect on the success of loyalty programs and determine the consequences of potential options. As a conclusion, the author emphasized three critical principles. The integration of loyalty programs into the company’s strategy and processes, the appropriate measure of returns with systematic tracking and the unique, mostly emotional and entertaining characteristics of the program can be crucial.

Horizontal diversity of higher education institutions. The case of Hungary – in European context

In the European Higher Education Area the diversification of higher education is considered to be an emphasized value, a guarantee of creativity. The various institutional rankings are the displays of vertical diversity, but in parallel with these, there is an increasing attention directed at horizontal diversity, the entirety of the institutions' activities. The European Mapping Project (U-map) undertook this challenge. The paper presents the research program, which is an attempt to adapt the U-map model to Hungary. According to the results, the U-map method which was intended for application on an international level, is very useful in the identification of the main groups of institutions in a specific national higher education system as well, and may provide a basis for the creation of institutional strategies and the development of the institutions’ network.

The Timing of Motherhood While Earning a PhD in Engineering

In spite of tremendous efforts, women are still under-represented in the field of science. Post-graduate education and early tenure track employment are part of the academic career establish-ment in research and development during periods that usually overlap with family formation. Though women tend to leave science mainly after obtaining their PhD, and the timing of mother-hood plays a vital role in a successful research career, qualitative data on this life period are scarce. Our paper focuses on how the normative and institutional contexts shape female PhD engineering students’ family plans. The research was based on intersections of life course and risk and uncertainty theories. Using qualitative interviews we explored how contradicting social norms of childbearing cause tensions in postgraduate students’ lives, and how the different uncer-tainties and risks permeate young researchers’ decisions on early life events. We concluded that, despite the general pattern of delaying motherhood among higher educated women, these students struggle against this postponement, and they hardly have any good options to avoid risk stem-ming from uncertainties and from some characteris-tics of studying and working in engineering. Find-ings of this research may call the attention of stake-holders to possible intervention points.
