In this paper we present findings from our empirical study of software process improvement (SPI) implementation. We aim to provide SPI practitioners with insight into designing appropriate SPI implementation initiatives in order to achieve better results. Thirty-four interviews were conducted with Australian practitioners. Three SPI implementation issues were investigated: reasons for embarking...
Software process improvement (SPI) is a widely recognized approach that software companies implement to improve quality, productivity, and time-to-market. Assessing and analyzing performance improvements are important SPI activities. However, many SPI managers have found it difficult to develop and implement effective performance measurement programs for SPI, in part because guidelines for cond...
شناخت خصوصیات ژئوتکنیکی ساختگاه سدها از مهمترین مراحل اکتشافی برای بدست آوردن اطلاعات لازم در طراحی و ساخت آنها می باشد. از آنجا که سدها نقش بسیار مهمی در استفاده ی بهینه از منابع آب دارند، حفظ پایداری آن ها و آب ذخیره شده در مخزن اهمیت بالایی دارد. در این تحقیق، نفوذپذیری و پارامترهای ژئومکانیکی توده سنگ ساختگاه سد سرداب، واقع در جنوب غربی فریدون شهر استان اصفهان، توسط روش های مختلف مورد ارزی...
When starting the software process improvement (SPI) journey, there are many SPI standards toselect from. Selecting good SPI standards can be a technical problem, from a software engineeringpoint of view, but it can also be a political problem, some standards fitting more with internal politicalagendas than others. As it is well-known that SPI without management commitment can have<...
BACKGROUND Previous reports suggest that beneficial effects of soy on bone quality are due to the estrogenic actions of isoflavone phytochemicals associated with the protein. However, mechanistic studies comparing the effects of soy diet and estrogens on bone, particularly in rapidly growing animals are lacking. METHODOLOGY AND PRINCIPAL FINDINGS We studied the effects of short term feeding o...
Context: Software Process Improvement initiatives have been around for many years with the growing globalisation of software development is making them increasingly important. Objective: The objective of this exploratory research is to gain an in-depth understanding of barriers that can undermine SPI, in the context of Global Software Development, from the perspective of software development pr...

Overexpression of the transcription factor Spi-1/PU.1 in mice leads to acute erythroleukemia characterized by a differentiation block at the proerythroblastic stage. In this study, we made use of a new cellular system allowing us to reach graded expression of Spi-1 in preleukemic cells to dissect mechanisms of Spi-1/ PU-1 in erythroleukemogenesis. This system is based on conditional production ...
Previously it was shown that the Ets proteins, PU.1 and Spi-B, exhibit functional redundancy in B lymphocytes. To investigate the possibility that PU.1 or Spi-B or both share overlapping roles with Ets-1 or Elf-1, PU.1(+/-)Ets-1(-/-), PU.1(+/-)Elf-1(-/-), and Spi-B(-/-)Ets-1(-/-) animals were generated. No blood cell defects were observed in these animals except those previously reported for Et...
Acute leukemias are characterized by deregulation of transcriptional networks that control the lineage specificity of gene expression. The aberrant overexpression of the Spi-1/PU.1 transcription factor leads to erythroleukemia. To determine how Spi-1 mechanistically influences the transcriptional program, we combined a ChIP-seq analysis with transcriptional profiling in cells from an erythroleu...
