On the job rotation problem

The job rotation problem (JRP) is the following: Given an $n \times n$ matrix $A$ over \Re \cup \{\ -\infty\ \}\ and $k \leq n$, find a $k \times k$ principal submatrix of $A$ whose optimal assignment problem value is maximum. No polynomial algorithm is known for solving this problem if $k$ is an input variable. We analyse JRP and present polynomial solution methods for a number of special cases

A Document that Transcends Itself: Between Abstraction and Reality

In A Document that Transcends Itself: Between Abstraction and Reality, I first present a historical analysis of photography that complicates traditional assumptions of how photographs operate in the world. Rather than functioning as merely an objective record, the photograph takes on a dual status as both a document and an abstraction from reality. The photograph’s ability to selectively decontextualize the origins from which it came from and present itself as something other than what it simply records becomes the core of my artistic practice. This paper will also discuss my conceptual investigations into how we perceive photographs when they are placed into new contexts, which inevitably change their meaning. Rather than fixed and unchanging, the photograph is fluid and multivalent in its interpretation. A Document that Transcends Itself: Between Abstraction and Reality presents a self-reflexive practice that attempts to deconstruct and understand the very nature of the medium

We, Not Me: The Musical Life of Bob Cranshaw

This study focuses on the career of Bob Cranshaw by examining his musical attributes and his leadership within the jazz community. Cranshaw’s career exceeded sixty years and yielded more than 400 recordings with artists such as Sonny Rollins, Ella Fitzgerald, James Brown, Paul Simon, Rod Stewart, Dexter Gordon, and numerous others. His career is examined using recordings, interviews, articles, discographies, and other publications. Biographical information about Cranshaw’s upbringing, education, military service, and family dynamic offers perspective on how he established himself as a professional bassist and clarifies certain important decisions regarding his work. A timeline of Cranshaw’s career is constructed using discographies, articles, and interviews to show the development of his professional life. New interviews with Cranshaw, his colleagues, and his students further illuminate the range and scope of his work musically and non-musically. The identification of important events and key elements in Cranshaw’s professional and personal life makes it possible to better understand how and why he achieved success. In so doing, this study recognizes Cranshaw’s significant place in jazz history

Social Media and Journalism: 10 Years Later, Untangling Key Assumptions

Amid a broader reckoning about the role of social media in public life, this article argues that the same scrutiny can be applied to the journalism studies field and its approaches to examining social media. A decade later, what hath such research wrought? We need a more particular accounting of the assumptions, biases, and blind spots that have crept into this line of research as well as the study of mediated conversations broadly. Our purpose is to provoke reflection and chart a path for future research by critiquing themes of what has come before. In particular, we seek to untangle three faulty assumptions—often implicit but no less influential—that have been overlooked in the rapid take-up of social media as a key phenomenon for journalism studies particularly and digital media studies generally: (1) that social media would be a net positive; (2) that social media reflects reality; and (3) that social media matters over and above other factors

Beyond the Introductory Information Systems Course: A Mini-Course series for Business Students

In order to be competitive in this increasingly complex world of information technology, business and industry, government, and entrepreneurs must be aware of the proper application of technology and must manage it effectively. Undergraduate students need more than an introductory survey course; they need in-depth application of technology to real problems. This mini-course approach is designed to motivate students with hands-on software applications and systems design concepts. The minicourse series is comprised of one-credit modules, is project-oriented, and is scheduled to accommodate general business and liberal arts students in preparation for their application of information technology in the workplace

Closing the California Clean Energy Divide: Reducing Electric Bills in Affordable Multifamily Rental Housing with Solar+storage

This economic analysis indicates that pairing solar PV with battery storage systems can deliver significant electricity bill savings for California affordable housing residents and property owners.Battery storage is emerging as an effective new strategy for reducing electricity costs for affordable multifamily rental housing in California. Battery storage systems not only provide economic returns today, they can also preserve the value of solar in an evolving policy and regulatory environment. Because batteries empower owners of solar photovoltaic (PV) systems to take control of the energy they produce and when they consume it, storage can deliver deeper cost reductions that can be shared among affordable housing owners, developers, and tenants.California has installed numerous integrated solar and battery storage projects; however, few have served lowincome tenants or owners of affordable rental housing. This disparity is due to many factors, including a lack of information about the economics of these systems in multifamily housing. To provide that needed information, Clean Energy Group, California Housing Partnership, and Center for Sustainable Energy, with analytical support from Geli, are embarking on a series of reports on solar and storage in California affordable multifamily rental housing.This first report examines the utility bill impacts of adding battery storage to stand-alone solar in affordable rental housing facilities in California's three investor-owned utility service territories, each with different rate structures. It is the first such report ever completed on these technologies in this sector in California.The report reaches several key conclusions:Under current utility rate tariffs, the combination of solar and storage technologies could virtually eliminate electric bills for many owners of affordable housing properties. Unlike stand-alone solar, which reduces energy consumption expenses but does little to offset demand related charges, a properly sized solar and battery storage system can eliminate nearly all electricity expenses, resulting in an annual electric utility bill of less than a few hundred dollars in some cases.It makes good economic sense today for solar and battery storage to be installed in affordable multifamily rental housing in California. The addition of battery storage to solar improves the economics of each property analyzed across all utility territories, reducing project payback by over three years in some cases.The addition of storage technologies has the potential to nearly double stand-alone solar electricity bill savings at about a third of the cost of solar. For example, the addition of a $112,100 battery storage system to a$385,000 solar installation increased savings from $15,000 per year to$27,900, an 85 percent increase in savings for only a 29 percent increase in cost

The effects of cystatin C construct clones on B16F10 in vitro cell behavior

Background: Metastasis is the cause of most cancer related morbidity. A naturally occurring cysteine protease inhibitor, cystatin C, has been reported to inhibit tumor cell metastasis for several different cancer types, however, the mechanism is still unknown. Our study focused on determining which region of cystatin C is responsible for anti-metastatic action by characterizing specific constructs of cystatin C in melanoma cells.  In one construct, the N-terminal peptide amino acids 1-10, required for cysteine protease inhibition, were deleted. In the second construct the conserved motif QLVA was altered to GGGG. Methods and Results: Net proliferation, migration and invasion of the cystatin C constructs were assessed. The modified Boyden chamber revealed 75% reduced invasion of N-truncated clones compared to control B16F10, similar to cystatin C overexpression. A scratch migration assay also showed a three-fold reduction in migration rate. The QLVA sequence was found to be required for inhibition of B16F10 invasion and migration. Net cell proliferation remained constant between clones. Conclusions: Overexpression of cystatin C with or without cysteine protease inhibitor activity inhibits the migration and invasion, but not proliferation, of B16F10 melanoma cells. The conserved cystatin sequence, QLVA, is required for cystatin actions on B16 melanoma cells

The Myth of Total Shakespeare: Filmic Adaptation and Posthuman Collaboration

The convergence of textuality and multimedia in the twenty-first century signals a profound shift in early modern scholarship as Shakespeare’s text is no longer separable from the diffuse presence of Shakespeare on film. Such transformative abstractions of Shakespearean linearity materialize throughout the perpetual remediations of Shakespeare on screen, and the theoretical frameworks of posthumanism, I argue, afford us the lens necessary to examine the interplay between film and text. Elaborating on André Bazin’s germinal essay “The Myth of Total Cinema,” which asserts that the original goal of film was to create “a total and complete representation of reality,” this article substantiates the posthuman potentiality of film to affect both humanity and textuality, and the tangible effects of such an encompassing cinema evince themselves across a myriad of Shakespearean appropriations in the twenty-first century (20). I propose that the textual discourses surrounding Shakespeare’s life and works are reconstructed through posthuman interventions in the cinematic representation of Shakespeare and his contemporaries. Couched in both film theory and cybernetics, the surfacing of posthuman interventions in Shakespearean appropriation urges the reconsideration of what it means to engage with Shakespeare on film and television. Challenging the notion of a static, new historicist reading of Shakespeare on screen, the introduction of posthumanist theory forces us to recognize the alternative ontologies shaping Shakespearean appropriation. Thus, the filmic representation of Shakespeare, in its mimetic and portentous embodiment, emerges as a tertiary actant alongside humanity and textuality as a form of posthuman collaboration

Competition, Change, and Coordination and Collaboration: Tracing news executives’ perceptions about participation in media innovation

Introduction Research Questions and Methods Results Discussion and conclusion Additional information Footnotes References Full Article Figures & data References Citations Metrics Licensing Reprints & Permissions View PDF View EPUB ABSTRACT Technological disruptions and increasing competition in the digital mediascape have fundamentally altered the market conditions for news media companies, raising corresponding concerns about the future of journalism. News media firms can adapt their business models by more purposefully focusing on media innovation, or the development and implementation of new processes, products or services. Specifically, this article focuses on innovation-centric coordination and collaboration—namely, coordination of knowledge and innovation activities among social actors in news media organizations. In doing so, this article builds on the knowledge-based view (KBV) of the firm and its core argument that coordination of knowledge is essential for organizational innovation. It presents findings from a series of cross-sectional surveys with newspaper executives carried out bi-annually from 2011 to 2017, examining executives’ perceptions of collaborative potential for digital media innovation at the intersection of editorial, business, and information technology (IT) departments. The findings suggest that there has been a significant increase in perceived collaboration more recently, and that the IT department is perceived to have become more important to innovation over time.This work was supported by Volda University College: [Grant Number Professor II research support to Oscar Westlund].publishedVersio
