An evaluation criterion for open source software projects: enhancement process effectiveness

Enhancement process is a key process in which open source software (OSS) project responds to user needs in terms of suggesting and implementing software features, thus the dimension of enhancement effectiveness corresponds nicely to adopters' concern about open source software. This study aims to construct a valid, reliable measurement model for the enhancement process effectiveness in an open source environment. We examine the validity and reliability of an initial list of indicators through two rounds of data collection and analysis from 240 and 750 OSS projects respectively, and come up with a measurement model for the effectiveness of enhancement process comprising four indicators. The implication of this measurement model for practitioners is explained through a numerical example followed by implications for research community.Griffith Sciences, School of Information and Communication TechnologyFull Tex

Hypothesis test using t-test to test the effect of individual variables, as well as the F-test to test the effect of variables simultaneously with a significance level of 5%. The results showed that the structure of the banking industry in Indonesia in 2009-2013 led to the traditional hypothesis, which profitability affected by market concentration. Market share has positive effect and not significant on profitability.

Search Engine Advertising Adoption and Utilization: An Empirical Investigation of Inflectional Factors

© Taylor & Francis Group, LLC. Search engine advertising (SEA) is a prominent source of revenue for search engine companies, and also a solution for businesses to promote their visibility on the web. However, there is little academic research available about the factors and the extent to which they may influence businesses’ decision to adopt SEA. Building on Theory of Planned Behavior, Technology Acceptance Model, and Unified Theory of Acceptance and Use of Technology, this study develops a context-specific model for understanding the factors that influence the decision of businesses to use SEA. Using structural equation modeling and survey data collected from 142 businesses, this research finds that the intention of businesses to use SEA is directly influenced by four factors: (i) attitude toward SEA, (ii) subjective norms, (iii) perceived control over SEA, and (iv) perceived benefits of SEA in terms of increasing web traffic, increasing sales and creating awareness. Furthermore, the research we discover six additional factors that have an indirect influence: (i) trust in search engines, (ii) perceived risk of SEA, (iii) ability to manage keywords and bids, (iv) ability to analyze and monitor outcomes, (v) advertising expertise, and (vi) using external experts

Business Value Is not only Dollars - Results from Case Study Research on Agile Software Projects

Business value is a key concept in agile software development. This paper presents results of a case study on how business value and its creation is perceived in the context of agile projects. Our overall conclusion is that the project participants almost never use an explicit and structured approach to guide the value creation throughout the project. Still, the application of agile methods in the studied cases leads to satisfied clients. An interesting result of the study represents the fact that the agile process of many projects differs significantly from what is described in the agile practitioners’ books as best practices. The key implication for research and practice is that we have an incentive to pursue the study of value creation in agile projects and to complement it by providing guidelines for better client’s involvement, as well as by developing structured methods that will enhance the value-creation in a project

Pengaruh Kemasan dan Harga Jual Keripik dan Stik dari Tepung Komposit Keladi dan Ubijalar terhadap Penerimaan Konsumen

Introduksi pengolahan produk snack berbahan baku tepung komposit keladi dan ubijalar telah dilaksanakan di Desa Pelaga, Kabupaten Badung, Bali pada tahun 2013 dan 2014 dengan melibatkan KWT “Mekar Sari”. Penelitian pendahuluan menunjukkan bahwa produk keripik dan stik yang dibuat dari tepung keladi dan tepung ubijalar dengan perbandingan 3:2 dan 4:1 dapat diterima secara organoleptik (hedonik) oleh panelis. Analisis biaya produksi untuk produk keripik dan stik per kemasan 30 g adalah Rp 1.537,90 dan Rp 1.398,60; dengan R/C ratio 1,29 dan 1,17. Umur simpan produk sampai sekitar 34 minggu pada suhu ruang untuk produk stik yang disimpan dalam plastik PE 0,40 mm sebagai kemasan dalam dengan kertas karton sebagai kemasan luar. Produk snack dikemas dengan desain khusus dan diberi label nama “Keripik Labi” dan “Stick Labi” kemudian diperkenalkan kepada konsumen untuk mengetahui penerimaan konsumen terhadap produk. Studi melibatkan 32 responden. Data dikumpulkan melalui kuesioner semi-terbuka dan dianalisis secara deskriptif kualitatif sederhana. 84-97% panelis menyatakan bahwa informasi tanggal kadaluwarsa produk tidak jelas. Beberapa informasi lain juga dianggap masih agak jelas. Informasi pada kemasan yang tidak jelas membuat 10-15% konsumen menganggap produk tidak menarik sehingga mempengaruhi minat beli konsumen. Disamping itu, harga produk yang mahal juga berpengaruh pada minat beli konsumen (25-27%). Harga jual sebesar Rp 3.500,00 dianggap tidak sesuai untuk produk snack kemasan 30 g. Harga jual yang pantas/sesuai menurut mayoritas konsumen (89-90%) adalah kurang dari Rp 3.000,00.Hasil penelitian ini memang masih jauh dari yang diharapkan. Namun, hasil studi dapat menjadi masukan yang bermanfaat bagi petani untuk pengembangan produk secara komersial

Public Managers: Their Behavior, their Change Potential and the Behavior of Women and Men in Public Organizations

This survey article addresses three questions based on the assumption that significant differences exist between public and private organizations. If this assumption is correct managerial and leadership behavior will differ between public and private managers. Additionally, the propensity to change will also differ between public and private managers. Since a number of studies indicate that managers’ leadership behavior in public organizations differ from that of private managers, difference and similarities in leadership behavior between women and men in public organizations are examined. Three studies are presented here which show that public and private managers have different behavioral patterns of leadership. However, public managers turn out to be more change- oriented than business managers. In the public organizations investigated no differences in leadership behavior between women and men were found
