Salaries of information technology managers; A trend analysis

During the economic boom of the last decade, companies and organizations have to offer lucrative salaries and a wide variety of incentive programs to attract and to retain highly skilled IT workers. While it is true that the economic downturn has affected the dramatic rise in salary trends, determining the worth of an employee as measured by wages will always remain a critical management issue. History has shown that irrespective of economic conditions, salaries will continue to rise. As the economy recovers and given the projected mass exodus of governmental information technology workers in the coming years, managers will need to be ready to deal with the difficult issue of high salary again. This study examines national and regional salary trends of IT managers. Specifically, the salaries examined are for the years 1991 through 2000, the period where salaries were often adjusted because of the imbalance between the supply of and the demand for IT professionals. From the employee who is looking for a reasonable salary package to the employer who must determine a sufficient pay raise to retain an IT manager, the findings and trends reported in this study should be useful and interesting

A Study of the Demand for Information Technology Professionals in Selected Internet Job Portals

The demand for information technology (IT) professionals has grown rapidly in the last decade. Parallel to this increasing need for IT personnel is the continuous change in the type of skills that are brought about by innovations in cutting edge technologies. However, the type of new IT skills and knowledge needed to keep companies competitive in the global market extend beyond the ability to apply the updated hardware and software to make business processes more efficient. Communication excellence and managerial expertise are just two of the other more commonly needed skills demanded by employers. This study identifies and classifies information technology related job listings that are disclosed in the databases of two leading e-recruiting services. Two secondary variables, written and oral communications and experience, were also collected and examined in this study. The results of this research should be of interest to job seekers, human resources administrators, career counselors, corporate trainers, information systems consultants, labor attorneys, immigration and naturalization officers, and agency recruiters. Educators will find the outcomes of this study useful for the design and development of new curricula that can prepare students for the job market. Students will find this study particularly helpful since the trends identified in this research can have important implications for them in their selection of elective courses and in choosing a track for specialization

Towards a Framework for Perceived Effectiveness of Mobile Learning

Recent years have witnessed rapid advancement in mobile learning technology. A major issue is the identification of thefactors that would relate to the diverse needs of users. If mobile learning is intended to enhance distance, interactive, andcollaborative learning, then it is mission critical to understand the impact of individual, social, and technological factors thatwould play a role in the effectiveness of this learning model as perceived by its users. This paper addresses this need byproposing an integrated and a holistic model that depicts the factors that may have the potential to impact the perceivedmobile learning effectiveness. To operationalize the model constructs, a survey-based instrument will be developed based ona review of frameworks pertinent to technology acceptance, diffusion of innovation, and media richness, and of literaturerelated to e-learning. The conceptual model will be discussed, and the study conclusion, implications, and limitations will bepresented

Orthovoltage intraoperative radiation therapy for pancreatic adenocarcinoma

<p>Abstract</p> <p>Purpose</p> <p>To analyze the outcomes of patients from a single institution treated with surgery and orthovoltage intraoperative radiotherapy (IORT) for pancreatic adenocarcinoma.</p> <p>Methods</p> <p>We retrospectively reviewed 23 consecutive patients from 1990-2001 treated with IORT to 23 discrete sites with median and mean follow up of 6.5 and 21 months, respectively. Most tumors were located in the head of the pancreas (83%) and sites irradiated included: tumor bed (57%), vessels (26%), both the tumor bed/vessels (13%) and other (4%). The majority of patients (83%) had IORT at the time of their definitive surgery. Three patients had preoperative chemoradiation (13%). Orthovoltage X-rays (200-250 kVp) were employed via individually sized and beveled cone applicators. Additional mean clinical characteristics include: age 64 (range 41-81); tumor size 4 cm (range 1.4-11); and IORT dose 1106 cGy (range 600-1500). Post-operative external beam radiation (EBRT) or chemotherapy was given to 65% and 76% of the assessable patients, respectively. Outcomes measured were infield control (IFC), loco-regional control (LRC), distant metastasis free survival (DMFS), overall survival (OS) and treatment-related complications.</p> <p>Results</p> <p>Kaplan-Meier (KM) 2-year IFC, LRC, DMFS and OS probabilities for the whole group were 83%, 61%, 26%, and 27%, respectively. Our cohort had three grade 3-5 complications associated with treatment (surgery and IORT).</p> <p>Conclusions</p> <p>Orthovoltage IORT following tumor reductive surgery is reasonably well tolerated and seems to confer in-field control in carefully selected patients.

Effectiveness of national cervical cancer screening programme in Taiwan: 12-year experiences

BACKGROUND: We examined cervical cancer incidence before and after nationwide cervical cancer screening was initiated in Taiwan in mid-1995. RESULTS: The invasive cancer incidence decreased by 47.8% during 1995-2006 . The carcinoma in situ incidence increased 1.7-fold during 1995-2000, and decreased by 19.6% during 2000-2006. CONCLUSION: The Taiwan national programme has significantly decreased invasive cervical cancer

Neurotrophic factor GDNF promotes survival of salivary stem cells

Stem cell-based regenerative therapy is a promising treatment for head and neck cancer patients that suffer from chronic dry mouth (xerostomia) due to salivary gland injury from radiation therapy. Current xerostomia therapies only provide temporary symptom relief, while permanent restoration of salivary function is not currently feasible. Here, we identified and characterized a stem cell population from adult murine submandibular glands. Of the different cells isolated from the submandibular gland, this specific population, Lin-CD24+c-Kit+Sca1+, possessed the highest capacity for proliferation, self renewal, and differentiation during serial passage in vitro. Serial transplantations of this stem cell population into the submandibular gland of irradiated mice successfully restored saliva secretion and increased the number of functional acini. Gene-expression analysis revealed that glial cell line-derived neurotrophic factor (Gdnf) is highly expressed in Lin-CD24+c-Kit+Sca1+ stem cells. Furthermore, GDNF expression was upregulated upon radiation therapy in submandibular glands of both mice and humans. Administration of GDNF improved saliva production and enriched the number of functional acini in submandibular glands of irradiated animals and enhanced salisphere formation in cultured salivary stem cells, but did not accelerate growth of head and neck cancer cells. These data indicate that modulation of the GDNF pathway may have potential therapeutic benefit for management of radiation-induced xerostomia

Computerized quality control of radioimmunoassay in Korea.

Automated data processing and quality control of radioimmunoassays offer not only increased speed but also a more thorough and statistically rigorous analysis of results. An external quality assessment scheme for serum thyroxine, triiodothyronine and thyroid stimulating hormone (TSH) assays was performed in five nuclear medicine laboratories in Korea to compare with the assay performances of the World Health Organization Radioimmunoassay Program. The required radioimmunoassay kits were supplied through the International Atomic Energy Agency (IAEA). We have determined the weighted root mean squared error, and variance ratio as the indices of standard curve and also the average batch coefficient of variation (ABCV) as the parameters of response error relationship curve and precision profile. There was a good fit for the triiodothyronine assay, but 3 of 5 laboratories showed possible bad fit in the T4 and TSH assay systems. The ABCV was less than 5 percent for the T3 and T4 assay system, however for the TSH system, only 1 laboratory showed the ABCV value of less than 5 percent. We have also calculated the within batch variation (drift) and between laboratory variations

An Information-Centric Communication Infrastructure for Real-Time State Estimation of Active Distribution Networks

© 2010-2012 IEEE.The evolution toward emerging active distribution networks (ADNs) can be realized via a real-time state estimation (RTSE) application facilitated by the use of phasor measurement units (PMUs). A critical challenge in deploying PMU-based RTSE applications at large scale is the lack of a scalable and flexible communication infrastructure for the timely (i.e., sub-second) delivery of the high volume of synchronized and continuous synchrophasor measurements. We address this challenge by introducing a communication platform called C-DAX based on the information-centric networking (ICN) concept. With a topic-based publish-subscribe engine that decouples data producers and consumers in time and space, C-DAX enables efficient synchrophasor measurement delivery, as well as flexible and scalable (re)configuration of PMU data communication for seamless full observability of power conditions in complex and dynamic scenarios. Based on the derived set of requirements for supporting PMU-based RTSE in ADNs, we design the ICN-based C-DAX communication platform, together with a joint optimized physical network resource provisioning strategy, in order to enable the agile PMU data communications in near real-time. In this paper, C-DAX is validated via a field trial implementation deployed over a sample feeder in a real-distribution network; it is also evaluated through simulation-based experiments using a large set of real medium voltage grid topologies currently operating live in The Netherlands. This is the first work that applies emerging communication paradigms, such as ICN, to smart grids while maintaining the required hard real-time data delivery as demonstrated through field trials at national scale. As such, it aims to become a blueprint for the application of ICN-based general purpose communication platforms to ADNs

It's not only about technology, it's about people: interpersonal skills as a part of the IT education.

Proceedings of: Second World Summit on the Knowledge Society (WSKS 2009), Chania, Crete, Greece, September 16-18, 2009.The importance of what have been termed the "soft skills" for the professional development of IT professionals is beyond any doubt. Taking account of this circumstance, the objective of the current research may be phrased as two separate questions. In the first place, determining the importance which IT related degree students place on these types of competencies for their professional future. In the second place, the importance which the development of the mentioned competencies has been given during their studies. The realization of an empirical study has fulfilled the two objectives described. The results demonstrate, on the one side, the moderate relevance which students assign to interpersonal competencies, especially emotional competencies, in contrast to the international curricular recommendations and studies concerning labor markets. On the other hand, the results indicate the scarce emphasis which lecturers have placed on the development of such competencies.Publicad
