Joint Ownership and Organizational Role: Critical Factors of IT-Driven Value

The concept of psychological ownership is used to enhance our understanding of the relationship between users and information technology professionals, and to describe the IT-business process relationship. We propose that the user-IT ownership interaction determines the role that IT professionals assume in the organization: partner, order taker, advisor or technocrat. Interviews at four major organizations support the existence of these roles, and indicate that the particular role assumed by the IT professionals is likely to be related to the value generated by IT. The study suggests that the highest IT value stems from partnership between the users and the individuals in the IT function, which requires both business process ownership by IT professionals and information system ownership by users

Contributing Your Wisdom or Showing Your Cards: A Quantitative Inquiry of Knowledge Sharing Behavior

In recent years, attempts to capture and leverage a firm’s knowledge resources have become a primary focus in the pursuit of competitive advantage. Business leaders increasingly look to their firms’ bases of knowledge as their most critical strategic resource. This trend has led to the adoption of knowledge management initiatives aimed at leveraging the knowledge of individuals to advance the economic interests of an organization. Within such an effort, knowledge sharing behavior is an essential precondition for success. This study explores the determinants of knowledge sharing by applying Ajzen’s Theory of Planned Behavior to the context of knowledge management. The model provides support for an emphasis on relationship issues in the development of knowledge management programs. In addition, the model addresses both formal and informal features of organizational contexts that can affect knowledge sharing behavior. The model contributes to the study of knowledge management by addressing elements of a firm’s formal policies that may promote or inadvertently discourage knowledge sharing and by providing a robust framework for the analysis of knowledge sharing

Trigeminal Nerve Schwannoma of the Cerebellopontine Angle.

Introduction  Large and even moderate sized, extra-axial cerebellopontine angle (CPA) tumors may fill this restricted space and distort the regional anatomy. It may be difficult to determine even with high resolution magnetic resonance imaging (MRI) if the tumor is dural-based, or what the nerve of origin is if a schwannoma. While clinical history and exam are helpful, they are not unequivocal, particularly since many patients present with a myriad of symptoms, or conversely an incidental finding. We present an atypical appearing, asymptomatic CPA tumor, ultimately identified at surgery to be a trigeminal schwannoma. Case History  A 40-year-old man presented with new-onset seizure. MRI identified an incidental heterogeneously contrast-enhancing CPA lesion ( Fig. 1A - D ). The tumor was centered on the internal auditory canal (IAC) with no tumor extension into Meckel's cave, IAC or jugular foramen. Audiometry demonstrated 10db of relative left-sided hearing loss with 100% word recognition. Physical examination was negative for focal neurologic deficits. A retrosigmoid craniotomy was performed and an extra-axial, yellow-hued mass was encountered and resected, which was ultimately confirmed to originate from the trigeminal nerve ( Video 1 ). Gross total resection was achieved, and the patient recovered from surgery with partial ipsilateral trigeminal sensory loss and no other new neurologic deficits. Conclusion  Pure CPA trigeminal schwannomas are rare, but should be considered in the differential for enhancing CPA lesions. Although, Meckel's cave involvement is frequently observed, it is not universal, and pure CPA schwannomas of all cranial nerves IV-XII have been reported in the literature.

Quality of life at the dead sea region: the lower the better? an observational study

<p>Abstract</p> <p>Background</p> <p>The Dead Sea region, the lowest in the world at 410 meters below sea level, is considered a potent climatotherapy center for the treatment of different chronic diseases.</p> <p>Objective</p> <p>To assess the prevalence of chronic diseases and the quality of life of residents of the Dead Sea region compared with residents of the Ramat Negev region, which has a similar climate, but is situated 600 meters above sea level.</p> <p>Methods</p> <p>An observational study based on a self-administered questionnaire. Data were collected from kibbutz (communal settlement) members in both regions. Residents of the Dead Sea were the study group and of Ramat Negev were the control group. We compared demographic characteristics, the prevalence of different chronic diseases and health-related quality of life (HRQOL) using the SF-36 questionnaire.</p> <p>Results</p> <p>There was a higher prevalence of skin nevi and non-inflammatory rheumatic diseases (NIRD) among Dead Sea residents, but they had significantly higher HRQOL mean scores in general health (68.7 ± 21 vs. 64.4 ± 22, p = 0.023) and vitality (64.7 ± 17.9 vs. 59.6 ± 17.3, p = 0.001), as well as significantly higher summary scores: physical component score (80.7 ± 18.2 vs. 78 ± 18.6, p = 0.042), and mental component score (79 ± 16.4 vs. 77.2 ± 15, p = 0.02). These results did not change after adjusting for social-demographic characteristics, health-related habits, and chronic diseases.</p> <p>Conclusions</p> <p>No significant difference between the groups was found in the prevalence of most chronic diseases, except for higher rates of skin nevi and NIRD among Dead Sea residents. HRQOL was significantly higher among Dead Sea residents, both healthy or with chronic disease.</p

Leveraging Information Technology to Support Agents of World Benefit

There is much debate about social responsibility in the context of business and industry but not much in the context of information technology. We address this void by examining developments and innovations at the interface between information technologies and positive social change. In particular, the paper explores the role of information technology in three critical domains: connectivity, education, and economic development. The underlying premise of the authors is that information and communication technologies can serve agents of social innovation in underserved communities and that their consideration is vital to the success of many efforts that pursue global and sustainable change. We also submit that such issues ought to be integrated more centrally into the practice and scholarly mission of the IS discipline

Origin and evolution of the octoploid strawberry genome.

Cultivated strawberry emerged from the hybridization of two wild octoploid species, both descendants from the merger of four diploid progenitor species into a single nucleus more than 1 million years ago. Here we report a near-complete chromosome-scale assembly for cultivated octoploid strawberry (Fragaria × ananassa) and uncovered the origin and evolutionary processes that shaped this complex allopolyploid. We identified the extant relatives of each diploid progenitor species and provide support for the North American origin of octoploid strawberry. We examined the dynamics among the four subgenomes in octoploid strawberry and uncovered the presence of a single dominant subgenome with significantly greater gene content, gene expression abundance, and biased exchanges between homoeologous chromosomes, as compared with the other subgenomes. Pathway analysis showed that certain metabolomic and disease-resistance traits are largely controlled by the dominant subgenome. These findings and the reference genome should serve as a powerful platform for future evolutionary studies and enable molecular breeding in strawberry

The Passing of Print

This paper argues that ephemera is a key instrument of cultural memory, marking the things intended to be forgotten. This important role means that when ephemera survives, whether accidentally or deliberately, it does so despite itself. These survivals, because they evoke all those other objects that have necessarily been forgotten, can be described as uncanny. The paper is divided into three main sections. The first situates ephemera within an uncanny economy of memory and forgetting. The second focuses on ephemera at a particular historical moment, the industrialization of print in the nineteenth century. This section considers the liminal place of newspapers and periodicals in this period, positioned as both provisional media for information as well as objects of record. The third section introduces a new configuration of technologies – scanners, computers, hard disks, monitors, the various connections between them – and considers the conditions under which born-digital ephemera can linger and return. Through this analysis, the paper concludes by considering digital technologies as an apparatus of memory, setting out what is required if we are not to be doubly haunted by the printed ephemera within the digital archive

Regulation of Pancreatic microRNA-7 Expression

Genome-encoded microRNAs (miRNAs) provide a posttranscriptional regulatory layer, which is important for pancreas development. Differentiation of endocrine cells is controlled by a network of pancreatic transcription factors including Ngn3 and NeuroD/Beta2. However, how specific miRNAs are intertwined into this transcriptional network is not well understood. Here, we characterize the regulation of microRNA-7 (miR-7) by endocrine-specific transcription factors. Our data reveal that three independent miR-7 genes are coexpressed in the pancreas. We have identified conserved blocks upstream of pre-miR-7a-2 and pre-miR-7b and demonstrated by functional assays that they possess promoter activity, which is increased by the expression of NeuroD/Beta2. These data suggest that the endocrine specificity of miR-7 expression is governed by transcriptional mechanisms and involves members of the pancreatic endocrine network of transcription factors

Panel 07 Travelling to Other Worlds and Altered States of Consciousness: Human-Artificial relational interactions and living worlds in the Age of Aquarius

In popular consciousness, 1969 marked the completion of the 2,150 years astrological cycle and transition from the Age of Capricorn to the Age of Aquarius, as part of the 25,772 years natural gyroscopic precession of Earth's axis. It also marked the year when the Apollo 11 mission stepped foot on the Moon, broadcasted live on TV sets across the world. A year later, Gene Youngblood published his famous book on "expanded cinema," which aimed to opening the "horizons beyond the point of infinity" moving Humanity's "oceanic consciousness" towards a "cosmic consciousness." Since that time, media performance technologies have made huge leaps in modes and means of audio-visual representation, introducing interactive live technologies, cyber environments, virtual and augmented realities, establishing virtual utopian and/or dystopian Other Worlds in which humans co-exist via their Avatar personalities, developing primary artificial and human interactions via board games, and even developing spiritual interactions between humans and AI. This panel calls for papers focusing on the rapid development of "metaverses" as interactive fields and/or performances, as a means of mapping the emergence of a new universal meta-human consciousness, to reflect upon the role Anthropology can play as an active agent of change

On Multifractal Structure in Non-Representational Art

Multifractal analysis techniques are applied to patterns in several abstract expressionist artworks, paintined by various artists. The analysis is carried out on two distinct types of structures: the physical patterns formed by a specific color (``blobs''), as well as patterns formed by the luminance gradient between adjacent colors (``edges''). It is found that the analysis method applied to ``blobs'' cannot distinguish between artists of the same movement, yielding a multifractal spectrum of dimensions between about 1.5-1.8. The method can distinguish between different types of images, however, as demonstrated by studying a radically different type of art. The data suggests that the ``edge'' method can distinguish between artists in the same movement, and is proposed to represent a toy model of visual discrimination. A ``fractal reconstruction'' analysis technique is also applied to the images, in order to determine whether or not a specific signature can be extracted which might serve as a type of fingerprint for the movement. However, these results are vague and no direct conclusions may be drawn.Comment: 53 pp LaTeX, 10 figures (ps/eps
