Theorization and Translation in Information Technology Institutionalization: Evidence from Danish Home Care

Although institutional theory has become a more dominant perspective in information systems research, studies have only paid scant attention to how field dynamics and organizational processes coevolve during information technology institutionalization. Against this backdrop, we present a new conceptualization based on the "traveling of ideas" metaphor that distinguishes between theorization of ideas about IT usage across an organizational field and translation of such ideas into practical use of IT within particular organizations. Drawing on these distinct analytical views, we posit that IT institutionalization is constituted through recursive intertwining of theorization and translation involving both linguistic and material objects. To illustrate the detailed workings of this conceptualization, we apply it to a longitudinal study of mobile IT institutionalization within Danish home care. We demonstrate how heterogeneous actors within the Danish home care field theorized ideas about mobile IT usage and how these ideas translated into different local arrangements. Further, our account reveals a complex institutionalization process in which mobile IT was first seen as a fashionable recipe for improvement but subsequently became the subject of controversy. The paper adds to the emerging process and discourse literature on IT institutionalization by shedding new light on how IT ideas travel across a field and within individual organizations, how they transform and become legitimized over time, and how they take on different linguistic and material forms across organizational settings.
Oscillation-test strategy for analog and mixed-signal integrated circuits

A new low-cost test method for analog integrated circuits, called oscillation-test, is presented. During the test mode, the circuit under test (CUT) is converted to a circuit that oscillates. Faults in the CUT which cause a reasonable deviation of the oscillation frequency from its nominal value can be detected. Using this test method, no test vector is required to be applied. Therefore, the test vector generation problem is eliminated and the test time is very small because a limited number of oscillation frequencies is evaluated for each CUT. Due to its digital nature, the oscillation frequency can be easily interfaced to boundary scan. This characteristics imply that oscillation-test strategy is very attractive for wafer-probe testing as well as final production testing. In this paper, the validity of the proposed test method has been verified throughout some examples such as operational amplifiers and analog-to-digital converter (ADC).
Alternative Graphical Authentication for Online Banking Environments

Many financial institutes tend to implement a secure authentication mechanism through the utilization of the One-Time-Password (OTP) technique. The use of a hardware security token to generate the required OTP has been widespread. Despite the fact that this method provides a fairly high level of security, many systems have not taken into consideration the need for a secure alternative login method whenever the hardware token is unavailable. This paper discusses the authentication issues associated with current e-banking login implementations when the hardware security token is unavailable. The study was supported by a user survey to realize the constraints confronting the user while logging in to their online banking system. The result showed that many online banking users had multiple accounts and found carrying around several security tokens is inconvenient. Moreover, high proportion of the users had confidently accepted the concept of one-time graphical password as an alternative means of authentication. Therefore, a potential solution has been introduced along with a conceptual discussion. The proposal aims to consolidate several authentication mechanisms to unite their various advantages into one robust authentication system with consideration of usability. The composite mechanism comprises of a One-Time-Password combined with graphic-based authentication techniques.
Central neuregulin-1/ErbB signaling modulates cardiac function via sympathetic activity in pressure overload-induced heart failure

Objectives: Neuregulin-1 (NRG-1)/ErbB signaling in the heart is reported to have a crucial role in heart failure. We recently demonstrated that NRG-1 signaling has sympathoinhibitory effects in the brain cardiovascular control center. How this central signaling impacts sympathoexcitation in heart failure, however, is unknown. Here we examined the role of central NRG-1/ErbB signaling in modulating the sympathetic nervous system in pressure overload-induced heart failure. Methods and results: Pressure overload-induced heart failure was induced in Wistar–Kyoto rats by banding the abdominal aorta. Rats were followed up for 15 weeks. Compared to sham-operated rats, aortic-banded rats showed left ventricle (LV) hypertrophy, LV dilation, and LV dysfunction [reducing fractional shortening (%fractional shortening), increased LV end-diastolic pressure, decreased positive and negative pressure differential (±dp/dtmax)], and increased urinary norepinephrine excretion. Aortic banding led to reduced expression of NRG-1 in the brainstem at 10 weeks after banding and reduced expression of ErbB2 at 5 weeks, but did not affect ErbB4. Central administration of recombinant NRG-1&bgr; at 5 weeks for 2 weeks attenuated LV hypertrophy, improved LV dilatation, prevented LV dysfunction (improvement of %fractional shortening and ±dp/dtmax, and reduction of LV end-diastolic pressure), and lowered urinary norepinephrine excretion at 10 weeks, and these effects were still observed at 15 weeks. Conclusion: NRG-1/ErbB signaling in the brainstem is impaired during the progression of pressure overload-induced heart failure. Activation of central NRG-1 signaling improves cardiac function through sympathoinhibition. These findings provide a new treatment concept and support the benefit of NRG-1 treatment in heart failure.
Divided over Diversity: Political Discourse in a Chicago Neighborhood

In a Chicago neighborhood made up of different racial and economic groups, nearly everyone claims to value diversity. Yet, this powerful and plastic symbol can influence political activity in opposite directions. An ethnographic study of the neighborhood shows how three different groups—white real estate professionals and politicians, white progressive organizers, and black low‐income housing advocates—deploy diversity. It presents three key findings: (1) mixed‐income housing often becomes a proxy for diversity; (2) the diversity concept can support progressive politics while downplaying certain racial and class disparities; and (3) a focus on neighborhood diversity can obscure issues that poor people care about, including tenants rights. By providing a microlevel perspective on diversity discourse, these findings demonstrate how a shared symbol can both illuminate and veil fundamental disagreements over race, class, inequality, and gentrification in cities today.
Value Creation and Value Claiming in Strategic Outsourcing Decisions: A Resource Contingency Perspective

This study integrates the concepts of value creation and value claiming into a theoretical framework that emphasizes the dependence of resource value maximization on value-claiming motivations in outsourcing decisions. To test this theoretical framework, it develops refutable implications to explain the firm's outsourcing decision, and it uses data from 178 firms in the publishing and printing industry on outsourcing of application services. The results show that in outsourcing decisions, resource value and transaction costs are simultaneously considered and that outsourcing decisions are dependent on alignment between resource and transaction attributes. The findings support a resource contingency view that highlights value-claiming mechanisms as resource contingency in interorganizational strategic decisions.
vTurbo: Accelerating Virtual Machine I/O Processing Using Designated Turbo-Sliced Core

In a virtual machine (VM) consolidation environment, it has been observed that CPU sharing among multiple VMs will lead to I/O processing latency because of the CPU access latency experienced by each VM. In this paper, we present vTurbo, a system that accelerates I/O processing for VMs by offloading I/O processing to a designated core. More specifically, the designated core - called turbo core - runs with a much smaller time slice (e.g., 0.1ms) than the cores shared by production VMs. Most of the I/O IRQs for the production VMs will be delegated to the turbo core for more timely processing, hence accelerating the I/O processing for the production VMs. Our experiments show that vTurbo significantly improves the VMs' network and disk I/O throughput, which consequently translates into application-level performance improvement.
Inability of Cecal Microflora to Promote Reversion of Viable Nonculturable Campylobacter jejuni

Abstract Campylobacter jejuni cells are able to enter a viable but nonculturable (VBNC) state when they are suspended in water. In the present experiments we inoculated day-of-hatch leghorn and broiler chicks with normal gut microflora and subsequently challenged these with high doses of VBNC C. jejuni. The objective was to determine if the pre-establishment of a normal gut flora would enable VBNC Campylobacter to recover, revert to the vibrionic form, and colonize the cecum. Day-of-hatch leghorn and broiler chicks were gavaged through the esophagus with 0.75 ml of a continuous-flow culture of normal cecal organisms. Two days after gavage, the same chicks were gavaged with 0.75 ml (greater than 109 colony-forming units) of a VBNC suspension of C. jejuni. Seven days later, cecal contents were collected, serially diluted, and examined for the presence of viable culturable C. jejuni. Our results demonstrated that the VBNC C. jejuni cells were unable to revert to a vibrionic culturable form capable of colonizing the cecum.
Selective Downregulation of the High–Molecular Weight Form of Adiponectin in Hyperinsulinemia and in Type 2 Diabetes

OBJECTIVE—Adiponectin is an adipocyte-specific secretory protein found in circulation in several different forms and is present at significantly lower levels in the plasma of diabetic patients compared with that of insulin-sensitive individuals. We wanted to test whether insulin per se is a contributing factor toward lower plasma adiponectin concentrations and, if so, whether the splanchnic bed contributes to this phenomenon. RESEARCH DESIGN AND METHODS—We sampled femoral artery and hepatic venous samples and measured the high–molecular weight (HMW) and low–molecular weight (LMW) fractions of adiponectin in 11 type 2 diabetic and 7 nondiabetic subjects matched for age, sex, and BMI during basal conditions and during a hyperglycemic (∼9.5 mmol/l) hyperinsulinemic (∼700 pmol/l) clamp. RESULTS—Under these conditions, total arterial adiponectin, HMW, and the ratio of HMW to total adiponectin all were lower (P < 0.01) in the diabetic versus nondiabetic subjects, whereas the LMW form did not significantly differ. Under hyperinsulinemic conditions, total adiponectin levels dropped, primarily due to a reduction of the HMW form, whereas LMW forms were not significantly affected. CONCLUSIONS—HMW adiponectin and the ratio of HMW to total adiponectin are lower in individuals with diabetes than in nondiabetic subjects. We conclude that HMW adiponectin is downregulated in hyperinsulinemia and type 2 diabetes.
The factor structure of the Chinese version of the Edinburgh Postnatal Depression Scale (EPDS)

The psychometric properties of the Chinese version of the Edinburgh Postnatal Depression Scale (EPDS) were evaluated at the six‐week postnatal period. A shorter version, the EPDS‐6, was found to offer an optimal fit to our data and provides a sound psychometric basis for the development of an abbreviated version of the tool which may offer enhanced screening and predictive utility.
Iranian Teachers’ Attitudes towards the Use of Interactive Whiteboards in English Language Teaching Classrooms

This study explored the attitudes of Iranian teachers about utilizing Interactive White Boards (IWBs) in EFL classrooms. The main goal of this paper was to evaluate teachers’ beliefs about IWB use and frequency of IWB usage in Iranian schools. To achieve this aim, 174 EFL teachers who used IWB for instruction from different educational levels (grade 6 to 11) participated in this study. A questionnaire consisting of 22 questions was developed by the teacher-researcher based on an extensive literature review on related instructional theories and models. The questionnaire was distributed to the English teachers through both paper and e-mail. Teachers' beliefs and attitudes about the IWB use were studied with respect to four main themes: instructional effects, motivational effects, usability, and frequency. The findings of this study indicated that Iranian EFL teachers hold positive attitudes towards the effects of IWB use in their classrooms in general. It was also found that the more teachers frequently use IWBs, the more they improve their IWB competencies.
An Intelligent System for Vertebrate Promoter Recognition

A promoter, the DNA region encompassing a gene's transcription start site, largely controls the biological activation of a gene. Dragon Promoter Finder, an advanced system for promoter recognition in vertebrates, uses a collection of models based on multi-sensor integration, signal processing and artificial neural networks. The system minimizes the number of false-positive predictions for various pre-specified sensitivity levels and exhibits several times higher accuracy than other compared systems.
From Freedom Schools to Freedom University: Liberatory Education, Interracial and Intergenerational Dialogue, and the Undocumented Student Movement in the U.S. South

Freedom University is a modern freedom school that provides liberatory education and leadership development to undocumented students banned from Georgia’s top public universities following the passage of Policy 4.1. 6 in 2010. The author discusses how Freedom University draws from both the Southern Freedom School tradition and Latin American popular education methods to provide education for social action. The article also presents a first-hand account of interracial and intergenerational dialogues between undocumented youth and Student Nonviolent Coordinating Committee (SNCC) veterans, and features photographs that illuminate how undocumented youth recombine SNCC’s tactics of non-violent civil disobedience with new symbols and meanings. In doing so, the article demonstrates how the legacy of freedom schools and student activism in the Black Freedom Movement are shaping the new freedom dreams of undocumented youth today.
The Expression of Alkaline Phosphatase, Osteopontin, Osteocalcin, and Chondroitin Sulfate during Pectoral Fin Regeneration in Carassius auratus gibelio: A Combined Histochemical and Immunohistochemical Study

Abstract Dermal bone is an important component of the teleost fins, and its ability to regenerate after fin amputation appears to be unlimited. The organic bone matrix contain type I collagen fibers, proteoglycans enriched in chondroitin sulfate, and noncollagenous matrix protein such as osteocalcin, osteopontin, and osteonectin. These molecules are synthesized by fin osteoblasts. Inorganic components chiefly consist of calcium and phosphate that form crystals of hydroxyapatite. Fin rays are described as models to study ossification. Due to this, the identification of the components involved in the synthesis of the organic and inorganic components of lepidotrichial bone are of great interest for the analysis of skeletal disorders in fish ossification. The present study investigates expression of alkaline phosphatase, osteopontin, osteocalcin, and chondroitin sulfate during pectoral fin regeneration in Carassius auratus gibelio. Alkaline phosphatase reaction has been found in the epidermis covering the wound, proximal blastema, near the cells that surround newly-formed lepidotrichia matrix and the tips of regenerating fin rays. Osteopontin has been observed throughout the regeneration blastema but excluded from the scleroblasts lining the inner side of the lepidotrichia. Osteocalcin and chondroitin sulfate expression coincides with the onset of mineralization of lepidotrichial matrix, suggesting its involvement in bone mineralization.
Prospective and Retrospective Memory Problems in Regular Ecstasy Consumers: Is it Just About the Ecstasy?

Remembering to do things in the future (prospective memory) and remembering things in our past (retrospective memory) are important everyday memory skills. Several studies suggest an association between use of ecstasy (3,4-methylenedioxymethamphetamine) and impairments in prospective (remembering to remember) and retrospective memory (recollection of past events) [1, 2]. However, some research suggests that other drug use (e.g., cannabis), non drug use factors (e.g., intensive dancing, overheating) and general anxiety levels are more strongly associated with these cognitive deficits [3-5]. The aim of this research was to investigate the contribution of these factors to subjective prospective and retrospective memory errors in a large sample of regular ecstasy consumers.
A flexible navigation mechanism for complex data models

The paper presents a way to build ﬂexible navigation tools over a big dataset of well structured data models. The mechanism is underpinned by a search engine that is used to slice and dice the database. By applying a series of consecutive groupings, the result of a search query can be organized in a hierarchical structure and browsed using traditional user interface controls.
The causes and effects of English teachers’ turnover: A case from Afghanistan

One of the challenging issues that educational organizations in developing countries face in staffing classrooms with qualified teachers is the high rate of teachers’ turnover. It creates problems for schools, which eventually leads to substandard instruction and low student achievement. This research explores the causes of English teachers’ turnover in a Non-Government Educational Organization in Kabul, Afghanistan. The results indicate that lack of teachers’ motivation, low salary, communication gap between management and teachers, market opportunities for English teachers, workload, absence of career path and weak recruitment processes are the major factors contributing to teachers’ turnover in Afghanistan. The high teachers’ turnover leads to such negative effects as interruptions in learning process, behavioural adjustment of students with new teachers, continuous exposure of students with novice teachers, emotional detachments of students with their teachers and negative effects on students’ learning. The article concludes that educational organizations should deal with their teachers more humanely. Teachers retain and perform in an organization when they are valued, motivated and satisfied with their jobs and their professional status. In the absence of such environment, it is likely that educational organizations in Afghanistan would continue to struggle to attract and retain qualified teachers, which will eventually compromise on the achievements of their students. Considering the findings, creation of covenantal bond rather than contractual bond is suggested as a strategy that could be augmented by a transformational leadership, which can motivate the teachers to remain committed to their profession.
Development of lane departure warning system based on a Dual-Core DSP

A Dual-Core DSP Based lane departure warning system (LDWS) with a high dynamic range (HDR) CMOS camera is presented in this paper. We developed the HDR camera with the image sensor MT9V022, which has specifically been designed to support automotive imaging needs. Image data is transmitted across the vehicle as serial LVDS (low voltage differential signal) data, with reduced emissions and drastically improved immunity to external interference. The DSP image processor on LDWS works with operating frequency of 600MHz and the lane marking detection speed can be more than 25 frames per second. The presented fast adaptive lane detection algorithm is efficient and robust. And the Time to Lane Cross (TLC) criterion is used to determine when the vehicle is in danger of departing lane. The LDWS is equipped on the test vehicle and has been successfully verified for hundreds of kilometers on highway.
Serializable isolation for snapshot databases

Many popular database management systems implement a multiversion concurrency control algorithm called snapshot isolation rather than providing full serializability based on locking. There are well-known anomalies permitted by snapshot isolation that can lead to violations of data consistency by interleaving transactions that would maintain consistency if run serially. Until now, the only way to prevent these anomalies was to modify the applications by introducing explicit locking or artificial update conflicts, following careful analysis of conflicts between all pairs of transactions. This article describes a modification to the concurrency control algorithm of a database management system that automatically detects and prevents snapshot isolation anomalies at runtime for arbitrary applications, thus providing serializable isolation. The new algorithm preserves the properties that make snapshot isolation attractive, including that readers do not block writers and vice versa. An implementation of the algorithm in a relational DBMS is described, along with a benchmark and performance study, showing that the throughput approaches that of snapshot isolation in most cases.
Differential expression of the rat retinoid X receptor γ gene during skeletal muscle differentiation suggests a role in myogenesis

Even though previous studies have shown that transcripts encoding the murine retinoid X receptor γ (RXRγ) are present in skeletal muscle of mouse embryos and that cultured myoblasts are induced to differentiate upon retinoid treatment, a function for RXRγ and retinoids in mammalian myogenesis has not yet been identified. To begin to understand the possible role of RXRγ during mammalian myogenesis we isolated novel rat RXRγ cDNA sequences and examined in detail the spatio‐temporal expression pattern of RXRγ transcripts in relation to skeletal muscle differentiation in rat embryos and cultured myoblasts. We show that the onset of RXRγ expression coincides with the differentiation of limb myoblasts in vivo. In vitro, RXRγ is expressed in differentiating myoblasts, but not in proliferating myoblasts. In the myotome, however, RXRγ is first expressed after myoblast differentiation, with RXRγ transcripts being confined initially to its ventral region. Subsequently, RXRγ becomes expressed throughout limb and myotome‐derived muscle masses, and by the end of the primary myogenic wave, RXRγ transcripts are mainly confined to their periphery. This dynamic expression pattern of RXRγ during myogenesis suggests its possible involvement in the differentiation of limb myoblasts but excludes a role in the differentiation of early myotomal myoblasts.
