A Landslide Climate Indicator from Machine Learning

In order to create a Landslide Hazard Index, we accessed rain, snow, and a dozen other variables from the National Climate Assessment Land Data Assimilation System. These predictors were converted to probabilities of landslide occurrence with XGBoost, a major machine-learning tool. The model was fitted with thousands of historical landslides from the Pacific Northwest Landslide Inventory (PNLI)

A Study of the Influence of Public and Private Christian High School Education on Academic Achievement and Spiritual Formation of College Students

This investigation compared the influence of public and Christian high schools on the spiritual formation and academic achievement of college students. Recent high school graduates who attend a private, liberal arts university in the southeastern United States responded to an online survey and interview questions related to the influence of one’s high school experience on spiritual formation and academic achievement. Significant differences were found between high school type and the type of problems faced by students and teachers, students’ ability to intelligently defend their faith, and students’ perceived ability to function in a diverse world. Significant differences favoring Christian school graduates were also found related to high school’s influence on taking college classes seriously, helping others, defending beliefs, sharing their faith, appreciation for other cultures, taking responsibility for actions, ability to receive constructive feedback, and being honest with oneself. Suggestions for educational improvement from both public and private high school graduates include: the need for hiring and retaining inspiring teachers who model moral behavior daily; the need for school personnel to listen to students and involve them in decision making; better problem-solving skills by school administrators; less favoritism shown to certain students by teachers and administrators; greater focus on authentic learning in real-world contexts; and the need for academic freedom to discuss critical issues without fear of retribution by teachers, administrators, or other students

Application Portfolio Diversity and Software Maintenance Productivity:An Empirical Analysis

The research addresses the issue of productivity in application software maintenance. Specifically, it examines the effect of diversity in tools, techniques, hardware and software associated with the portfolio being maintained. In manufacturing environments, there is some evidence to suggest that production of products where there is little sharing of inputs and production processes reduces focus and results in lower manufacturing performance (Skinner, 1974). In economics, it is argued that there are cost complementarities or economies of scope in sharing common inputs and processes among various products with commonalities in production, and diseconomies of scope when inputs and processes differ (Panzar and Willig, 1977, 1981). In the software maintenance context, the issue of diversity and its effect on productivity is particularly salient. Software maintenance is work done to enhance software functionality, correct errors and improve the performance of software (Schneidewind, 1987). It is a costly activity for organizations, requiring from 50 to 80% of the Information Systems (IS) budget and representing more than threefourths of software costs on a life cycle basis (Arthur, 1988). Application portfolio diversity, i.e.,differences in technical platforms, software languages, and development tools and techniques in the set of the organization\u27s software systems, arises as a consequence of the organization\u27s information technology infrastructure decisions. To meet a particular customer need, an IS group acquires or develops software using a certain tool, methodology, and hardware platform. However, it may be that the software does not fit well into the organization\u27s existing technical platform. Furthermore, the software may have been developed using a different methodology or tools than other software systems in the organization\u27s portfolio. This diversity may have the result of increased difficulty in software maintenance because software enhancement can require modification of multiple software systems that have been created using a variety of languages, tools and techniques. The results of our analysis suggest that software portfolio diversity reduces productivity in software maintenance. Potential inefficiencies from diversity in software maintenance can arise from several causes. Switching costs are incurred due to multiple, varied process flows and frequent change over in processes required when modifying software created using different methodologies and tools. Diversity may also increase the difficulty of software quality control, testing and verification; for example, inefficiencies may occur due to the complexities of conducting system and integration testing across multiple technical platforms. Finally, there may be costs due to the difficulties in selecting project team members with the multiple and varied skills required to modify diverse sets of software

The poverty of journal publishing

The article opens with a critical analysis of the dominant business model of for-profit, academic publishing, arguing that the extraordinarily high profits of the big publishers are dependent upon a double appropriation that exploits both academic labour and universities’ financial resources. Against this model, we outline four possible responses: the further development of open access repositories, a fair trade model of publishing regulation, a renaissance of the university presses, and, finally, a move away from private, for-profit publishing companies toward autonomous journal publishing by editorial boards and academic associations. </jats:p

Driving calmodulin protein towards conformational shift by changing ionization states of select residues

Proteins are complex systems made up of many conformational sub-states which are mainly determined by the folded structure. External factors such as solvent type, temperature, pH and ionic strength play a very important role in the conformations sampled by proteins. Here we study the conformational multiplicity of calmodulin (CaM) which is a protein that plays an important role in calcium signaling pathways in the eukaryotic cells. CaM can bind to a variety of other proteins or small organic compounds, and mediates different physiological processes by activating various enzymes. Binding of calcium ions and proteins or small organic molecules to CaM induces large conformational changes that are distinct to each interacting partner. In particular, we discuss the effect of pH variation on the conformations of CaM. By using the pKa values of the charged residues as a basis to assign protonation states, the conformational changes induced in CaM by reducing the pH are studied by molecular dynamics simulations. Our current view suggests that at high pH, barrier crossing to the compact form is prevented by repulsive electrostatic interactions between the two lobes. At reduced pH, not only is barrier crossing facilitated by protonation of residues, but also conformations which are on average more compact are attained. The latter are in accordance with the fluorescence resonance energy transfer experiment results of other workers. The key events leading to the conformational change from the open to the compact conformation are (i) formation of a salt bridge between the N-lobe and the linker, stabilizing their relative motions, (ii) bending of the C-lobe towards the N-lobe, leading to a lowering of the interaction energy between the two-lobes, (iii) formation of a hydrophobic patch between the two lobes, further stabilizing the bent conformation by reducing the entropic cost of the compact form, (iv) sharing of a Ca+2 ion between the two lobes

The economic and innovation contribution of universities: a regional perspective

Universities and other higher education institutions (HEIs) have come to be regarded as key sources of knowledge utilisable in the pursuit of economic growth. Although there have been numerous studies assessing the economic and innovation impact of HEIs, there has been little systematic analysis of differences in the relative contribution of HEIs across regions. This paper provides an exploration of some of these differences in the context of the UK’s regions. Significant differences are found in the wealth generated by universities according to regional location and type of institution. Universities in more competitive regions are generally more productive than those located in less competitive regions. Also, traditional universities are generally more productive than their newer counterparts, with university productivity positively related to knowledge commercialisation capabilities. Weaker regions tend to be more dependent on their universities for income and innovation, but often these universities under-perform in comparison to counterpart institutions in more competitive regions. It is argued that uncompetitive regions lack the additional knowledge infrastructure, besides universities, that are more commonly a feature of more competitive regions

The dynamics of university units as a multi-level process. Credibility cycles and resource dependencies

This paper presents an analysis of resource acquisition and profile development of institutional units within universities. We conceptualize resource acquisition as a two level nested process, where units compete for external resources based on their credibility, but at the same time are granted faculty positions from the larger units (department) to which they belong. Our model implies that the growth of university units is constrained by the decisions of their parent department on the allocation of professorial positions, which represent the critical resource for most units’ activities. In our field of study this allocation is largely based on educational activities, and therefore, units with high scientific credibility are not necessarily able to grow, despite an increasing reliance on external funds. Our paper therefore sheds light on the implications that the dual funding system of European universities has for the development of units, while taking into account the interaction between institutional funding and third-party funding
