This can be done in many different ways the platform may be developed from the ground up, an existing recommender engine may be contracted (OracleAS Personalization), code libraries can be adapted, or a platform may be selected and tailored to suit (LensKit, MymediaLite, Apache Mahout, etc.). In some cases, a combination of these approaches will be employed. For E-commerce projects, and particularly in the E-commerce website t, the ideal situation is to find an open-source platform with many active contributors that provides a rich and varied set of recommender system functions that meets all or most of the baseline development requirements. Short of finding this ideal solution, some minor customization to an already existing system may be the best approach to meet the specific development requirements. Various libraries have been released to support the development of recommender systems for some time, but it is only relatively recently that larger scale, open-source platforms have become readily available. In the context of such platforms, evaluation tools are important both to verify and validate baseline platform functionality, as well as to provide support for testing new techniques and approaches developed on top of the platform. Apache Mahout as an enabling platform for research and have faced both of these issues in employing it as part of work in collaborative filtering recommenders.","PeriodicalId":149561,"journal":{"name":"SIGMIS-CPR '13","volume":"559 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132481057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing literature has noted that female students are less likely to choose IT as an undergraduate major, while female IT professionals are more likely to leave the IT workforce. There is little study of an intermediate step i.e., if gender affects whether IT graduates take up their first job in IT. At the same time, the recession in developed economies has prompted research interest on its effects on IT jobs. This paper examines the intersection of these two phenomena i.e., it seeks to understand the influence of both gender and the recent recession on the likelihood of IT graduates taking up their first jobs in IT. It hypothesizes direct and interaction effects of gender and recession on the dependent variable. The hypotheses are tested through analyzing data from annual surveys of undergraduate students majoring in IT at a large public university over a 5-year period from 2007-2011 that includes the recent recession. As hypothesized, female IT graduates were found to be 7.5% less likely to enter IT jobs over this period than their male counterparts. We also found that the economic recession of 2009 has significant interaction with gender i.e., female IT students were 20.9% less likely to enter an IT job in 2009 than male IT students. We contribute to the literature by demonstrating that economic downturn and gender could significantly affect likelihood of entry job in IT, while most of the previous research considers the effects of individual characteristics. Our findings provide implications for IT students, IT employers, and government policy makers.","PeriodicalId":149561,"journal":{"name":"SIGMIS-CPR '13","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129679018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These eventualities present a stressful environment for emerging and tenured IS professionals. Firms are typically pressured to reduce costs by reducing IS staff only to revisit rehiring the same IS professionals. We investigated the phenomenon of IS professional career commitment to the IS profession using psychological contract theory (PCT) and affective events theory (AET). We present a model that examines the psychological contract in the IS profession (PCP), psychological contract breach in the profession (PCBP) and psychological contract violation in the profession (PCVP). We interviewed twenty-six IS professionals having experienced negative attributions in the IS profession where they reassessed their commitment to the profession (turnover intention) or left the field (turnover). Our results show that all interviewees remained in the field, suggesting the amount of negative conditions in the IS profession may be less significant to turnover. A deeper analysis of the qualitative data indicates that certain elements contribute to interest and commitment to the IS profession such as positive learning opportunities, challenges, and flexibility, such as profession specificity (programmer, CIO, analyst, and database administration). The vastness of the IS profession enables IS professionals to enter another capacity and still experience challenges and accomplishment. We present our implications of the results from a theoretical and practical position.","PeriodicalId":149561,"journal":{"name":"SIGMIS-CPR '13","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121368463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
