Strategizing discourse: strategy-as-practice and the discursive turn

Event synopsis: The "Strategy-as-Practice" (SAP) perspective seeks to illuminate the activity and practice of strategizing by re-conceptualising strategy as something that people do in organizations rather than something organizations have. The purpose of this sub-theme is to further expand the study of SAP so that it includes the study of discursive practices as a means by which to explore the socially situated, day-to-day shaping and transforming of strategy in organizations. Specifically, the sub-theme will explore the production, dissemination and consumption of strategy discourse(s), how these discourses are largely constituted, enacted, maintained or transformed through discursive work, and their implications for work and organisation. 
 
The SAP research agenda connects with the broader "practice turn" in contemporary social sciences by attending to the micro-level of social activity in particular organizational settings and to the location of such activity in relation to broader social, discursive and material practices. This sub-theme will therefore address multiple facets of discourse research including the textual, contextual, performative and material aspects of strategy-related discourses and will also address questions of research design and methodology.
Information Research in Leisure: Implications from an Empirical Study of Backpackers

In the modern, increasingly flat world, many individuals have seen an increase in the amount of leisure time they have available. This leisure time is used for different purposes, often including travel and tourism. Among the many types of travel and tourism, backpack or budget travelling is becoming more and more popular. This increasingly common leisure activity presumably involves intensive information search activities. This study places the backpackers’ search for travel information in an everyday life information seeking (ELIS) perspective. The search for information by backpackers can be seen as a three-stage information search process. In each stage, depending on the type of task, backpackers use various information resources for different purposes. Such sources may be used for more than one purpose and in more than one information search stage. However, their relative importance varies depending on the characteristics of the source of information and the information search stage in which the source is being used. In this article I suggest that studies of leisure information behaviors and leisure activities show theoretical and practical value for both the information seeking public and the information science community. We also suggest that library and information science scholars and practice communities direct attention and research resources to leisure research in general, and the concept of serious leisure and its structured information acquisition and sharing activities in particular. Information Research in Leisure: Implications from an Empirical Study of Backpackers
Models and Issues in Data Stream Systems

In this overview paper we motivate the need for and research issues arising from a new model of data processing. In this model, data does not take the form of persistent relations, but rather arrives in multiple, continuous, rapid, time-varying data streams. In addition to reviewing past work relevant to data stream systems and current projects in the area, the paper explores topics in stream query languages, new requirements and challenges in query processing, and algorithmic issues.
Consumers ’ Stock Preferences beyond Expected Financial Returns : The Influence of Product and Brand Evaluations Structured

Purpose – The purpose of this paper is to examine the links between individual investors’ subjective evaluations of certain companies’ products and brands, on one hand, and their willingness and decisions to invest in those companies’ stocks, on the other. The authors aim to challenge the traditional assumption that individuals would make stock investment decisions purely on the basis of expected financial returns and risks. Design/methodology/approach – Survey data were collected from 293 individuals who invest in the stock market of a European country and analyzed with PLS path modeling. Findings – In the clear majority of the consumers’ stock investment decisions that were analyzed, the consumers exhibited some willingness to invest in a chosen stock beyond its expected financial returns/risk. Two variables are found to elicit willingness to invest in a company’s stock beyond its financial returns: the personal relevance that the individual attaches to domains (activities or areas of interest; ideas or ideals) supported or represented by the company’s products; and the individual’s affective evaluation of the company’s product brand. Research limitations/implications – Replicating the study with different companies from different industries and with consumers from different countries will be important. Overcoming a potential retrospection bias in the reported study is also a task for further research. Practical implications – The findings provide insights that can serve segmentation, targeting, and positioning when it comes to marketing a company in the stock market so as to attract investors. Originality/value – The paper provides new evidence on the influence of product and brand evaluations in consumers’ stock investment decisions – suggesting that positive product evaluations elicit extra willingness to invest in a company’s stock, over and beyond its financial returns.
Random sorting networks

UW-PIMS Mathematics Colloquium: Alexander Holroyd (Random Sorting Networks) Sorting a list of items is perhaps the most familiar problem of computer science. If one must do this by swapping neighbouring pairs, the worst initial condition is when the n items are in reverse order, in which case n choose 2 swaps are needed. A sorting network is any sequence of n choose 2 swaps which achieves this. We consider a uniformly random n-item sorting network. Exact simulations and heuristic arguments have led to a wealth of astonishing conjectures about the n→in nity limit. For instance, the half-time permutation matrix is believed to be circularly symmetric, while the trajectories of items appear to converge to random sine curves; the best known bounds on the permutation matrices and trajectories are much weaker (but still non-trivial). The conjectures t together into a remarkable geometric picture. I'll also report on some recent progress on local sub-networks and random subnetworks, both of which shed some new light on this picture. Based on joint works with Omer Angel, Vadim Gorin, Dan Romik and Balint Virag. See http://www.math.ubc.ca/~holroyd/sort for pictures. Related Links: Pacific Institute for the Mathematical Sciences
Exploring the Robustness of the Oil Price-Macroeconomy Relationship

This paper reexamines the oil price-macroeconomy relationship with rolling Granger causality and structural stability tests. It finds that the relationship broke down amidst the falling oil prices and market collapse of the 1980s, suggesting misspecification of the oil price rather than a weakened relationship. Some proposed respecifications of the oil price yield considerable improvements, although they are not sufficient to achieve Granger causality of output unless interest rates are excluded from the VAR. There is some support for the explanation that oil prices affect the economy indirectly by inducing monetary policy responses, but this is incomplete and some evidence of misspecification remains. This paper was originally prepared for the U.S. Department of Energy Conference on the Macroeconomic Impacts of Oil Price Shocks, Washington DC, October 3-4, 1996. Financial support from Oak Ridge National Laboratory is gratefully acknowledged. I thank Andrew Filardo and Jeff Fuhrer for helpful comments. The views expressed are those of the author, and do not necessarily represent those of the Federal Reserve System. 1. Tests are of the hypothesis that all oil price coefficients are zero in 8 lag quarterly VARs which include GDP deflator inflation, the 3-month Treasury bill rate, and import inflation in addition to unemployment or output growth and an oil price. The two oil prices used are nominal log-differences and real log-levels (see the data appendix for exact definitions). The samples (before observations are lost to lags) begin in 1948:1 and run through 1995:2. 2
The Constant Comparative Analysis Method Outside of Grounded Theory

This commentary addresses the gap in the literature regarding discussion of the legitimate use of Constant Comparative Analysis Method (CCA) outside of Grounded Theory. The purpose is to show the strength of using CCA to maintain the emic perspective and how theoretical frameworks can maintain the etic perspective throughout the analysis. My naturalistic inquiry model shows how conceptual frameworks and theoretical frameworks can be integrated when using the CCA method.
Adding Attributes to Role-Based Access Control

Merging the best features of RBAC and attribute-based systems can provide effective access control for distributed and rapidly changing applications.
Location extraction from disaster-related microblogs

Location information is critical to understanding the impact of a disaster, including where the damage is, where people need assistance and where help is available. We investigate the feasibility of applying Named Entity Recognizers to extract locations from microblogs, at the level of both geo-location and point-of-interest. Our experimental results show that such tools once retrained on microblog data have great potential to detect the where information, even at the granularity of point-of-interest.
Cultural Attributes and Adaptations Linked to Achievement Motivation Among Latino Adolescents

This exploratory study examined whether associations between perceived school experiences and achievement motivation varied by language acculturation and generational status among a sample of immigrant and U.S. born Latino adolescents (n = 129). Ogbu’s (1993) notion of primary and secondary cultural differences was adapted to better suit comparisons within this Latino group using the terms cultural attributes and cultural adaptations. Academic competence, school belonging, and parent involvement were positively related to achievement motivation. Academic competence and parent involvement were strongly related to achievement motivation among students who spoke English or were born in the U.S., suggesting that these associations may be cultural adaptations. Future intervention programs for Latino students, regardless of acculturation or generational status, should focus on making them feel supported and included. Acculturated Latino youth and youth who have lived in the U.S. for a long time should be targeted for programs that enhance academic competence and parent involvement.
Trazodone Effects on Obstructive Sleep Apnea and Non-REM Arousal Threshold.

RATIONALE
A low respiratory arousal threshold is a physiological trait involved in obstructive sleep apnea (OSA) pathogenesis. Trazodone may increase arousal threshold without compromising upper airway muscles, which should improve OSA.


OBJECTIVES
We aimed to examine how trazodone alters OSA severity and arousal threshold. We hypothesized that trazodone would increase the arousal threshold and improve the apnea/hypopnea index (AHI) in selected patients with OSA.


METHODS
Subjects were studied on two separate nights in a randomized crossover design. Fifteen unselected subjects with OSA (AHI ≥ 10/h) underwent a standard polysomnogram plus an epiglottic catheter to measure the arousal threshold. Subjects were studied after receiving trazodone (100 mg) and placebo, with 1 week between conditions. The arousal threshold was calculated as the nadir pressure before electrocortical arousal from approximately 20 spontaneous respiratory events selected randomly.


MEASUREMENTS AND MAIN RESULTS
Compared with placebo, trazodone resulted in a significant reduction in AHI (38.7 vs. 28.5 events/h, P = 0.041), without worsening oxygen saturation or respiratory event duration. Trazodone was not associated with a significant change in the non-REM arousal threshold (-20.3 vs. -19.3 cm H2O, P = 0.51) compared with placebo. In subgroup analysis, responders to trazodone spent less time in N1 sleep (20.1% placebo vs. 9.0% trazodone, P = 0.052) and had an accompanying reduction in arousal index, whereas nonresponders were not observed to have a change in sleep parameters.


CONCLUSIONS
These findings suggest that trazodone could be effective therapy for patients with OSA without worsening hypoxemia. Future studies should focus on underlying mechanisms and combination therapies to eliminate OSA. Clinical trial registered with www.clinicaltrials.gov (NCT 01817907).
The Spring kernel: a new paradigm for real-time systems

A real-time operating system kernel, called the Spring kernel, that provides some of the basic support required for large, complex, next-generation real-time systems, especially in meeting timing constraints, is presented. The approach meets the need to build predictable yet flexible real-time systems. Most current real-time operating systems contain the same basic paradigms found in time-sharing operating systems and often use a basic priority-scheduling mechanism that provides no direct support for meeting timing constraints. Spring uses two criteria to classify tasks' interaction with and effects on the environment: importance and timing requirements. Implementation experience with Spring is described.<<ETX>>
Associations between rationing of nursing care and inpatient mortality in Swiss hospitals.

OBJECTIVE
To explore the relationship between inpatient mortality and implicit rationing of nursing care, the quality of nurse work environments and the patient-to-nurse staffing ratio in Swiss acute care hospitals.


DESIGN
Cross-sectional correlational design.


SETTING
Eight Swiss acute care hospitals examined in a survey-based study and 71 comparison institutions.


PARTICIPANTS
A total of 165 862 discharge abstracts from patients treated in the 8 RICH Nursing Study (the Rationing of Nursing Care in Switzerland Study) hospitals and 760 608 discharge abstracts from patients treated in 71 Swiss acute care hospitals offering similar services and maintaining comparable patient volumes to the RICH Nursing hospitals.


MAIN OUTCOME MEASURES
The dependent variable was inpatient mortality. Logistic regression models were used to estimate the effects of the independent hospital-level measures.


RESULTS
Patients treated in the hospital with the highest rationing level were 51% more likely to die than those in peer institutions (adjusted OR: 1.51, 95% CI: 1.34-1.70). Patients treated in the study hospitals with higher nurse work environment quality ratings had a significantly lower likelihood of death (adjusted OR: 0.80, 95% CI: 0.67-0.97) and those treated in the hospital with the highest measured patient-to-nurse ratio (10:1) had a 37% higher risk of death (adjusted OR: 1.37, 95% CI: 1.24-1.52) than those in comparison institutions.


CONCLUSIONS
Measures of rationing may reflect care conditions that place hospital patients at risk of negative outcomes and thus deserve attention in future hospital outcomes research studies.
Does the baricity of bupivacaine influence intrathecal spread in the prolonged sitting position before elective cesarean delivery? A prospective randomized controlled study.

BACKGROUND
Difficulties in inserting an epidural catheter while performing combined spinal-epidural anesthesia for cesarean delivery may lead to undue delays between the spinal injection of the local anesthetic mixture and the adoption of the supine position with lateral tilt. We hypothesized that this delay may affect the intrathecal distribution of local anesthetic of different baricities such that hypobaric local anesthetic would lead to a higher sensory block level.


METHODS
Healthy parturients with uncomplicated pregnancies undergoing elective cesarean delivery under combined spinal-epidural anesthesia were enrolled in this prospective double-blind randomized controlled trial. The subjects were allocated to receive hyperbaric (hyperbaric group), isobaric (isobaric group), or hypobaric (hypobaric group) spinal bupivacaine 10 mg. After the spinal injection, the subjects remained in the sitting position for 5 minutes (to simulate difficulty in inserting the epidural catheter) before being helped into the supine lateral tilt position. The primary outcome was the sensory block level during the 25 minutes after the spinal injection. Other end points included motor block score, maternal hypotension, and vasopressor requirements.


RESULTS
Data from 89 patients were analyzed. Patient characteristics were similar in all groups. The median [interquartile range] (95% confidence interval) sensory levels after spinal injection were significantly higher with decreasing baricity: hyperbaric T10 [T11-8] (T10-9), isobaric T9 [T10-7] (T9-7), and hypobaric T6 [T8-4] (T8-5) (P < 0.001, Cuzick trend). All patients in the hypobaric group reached a sensory block level of T4 at 25 minutes after spinal injection compared with 80% of the patients in both the isobaric and hyperbaric groups (P = 0.04; difference 20%, 95% confidence interval of difference 4%-33%). Significantly more patients in the hypobaric group had complete lower limb motor block (Bromage score = 4) (hyperbaric 43%, isobaric 63%, and hypobaric 90%; P < 0.001). The incidences of maternal hypotension and nausea and vomiting were similar among groups, although the ephedrine requirements were significantly increased in the isobaric and hypobaric groups by factors of 1.83 and 3.0, respectively, compared with the hyperbaric group (P < 0.001, Cuzick trend).


CONCLUSIONS
We demonstrated that when parturients undergoing cesarean delivery were maintained in the sitting position for 5 minutes after spinal injection of the local anesthetic, hypobaric bupivacaine resulted in sensory block levels that were higher compared with isobaric and hyperbaric bupivacaine, respectively, during the study period.
Differences in peri-implant conditions between fully and partially edentulous subjects: a systematic review.

AIM
The aim of this study was to compare peri-implant conditions between fully edentulous (FES) and partially edentulous subjects (PES).


MATERIAL AND METHODS
A systematic review was conducted. The MEDLINE, EMBASE and COCHRANE databases were searched for publications up to January 1st 2012. Studies reporting on the bleeding tendency of the peri-implant mucosa and/or studies reporting on the prevalence of peri-implant mucositis and/or peri-implantitis were considered.


RESULTS
Fifty-five publications describing 46 studies were selected. One study described both FES and PES, and all other studies described either FES or PES. Subgroup analyses were performed according to dental status (fully/partially edentulous), follow-up time (≥5 years and ≥ 10 years) and study design (prospective/cross-sectional). FES harboured more plaque at their implants than PES. Modified bleeding index scores were significantly higher in FES, but no differences in bleeding on probing, implant loss and probing pocket depth were observed between FES and PES. No meta-analysis could be performed on prevalence of peri-implant mucositis and peri-implantitis. Overall prevalence of peri-implantitis was 0-3.4% after 5 years and 5.8-16.9% after 10 years of implant evaluation.


CONCLUSION
FES and PES show comparable implant survival rates. However, no conclusion can be drawn regarding differences in prevalence of peri-implant mucositis and peri-implantitis between FES and PES.
The future of automation in bacteriology.

Bacteriology remained essentially manual for many years. After a partial automation for blood cultures, identifications and sensitivity testing, new technological developments including robotisation and digital pictures made it possible to open new ways. In the context of economic pression and need to increase the quality, automation offers multiple advantages concerning increase of productivity, standardization, traceability and decreasing of the delay to obtain the results. Moreover the use of digitalized pictures opens the way to tele-bacteriology, particularly useful when considering the merging of hospital laboratories because it makes it possible to geographically dissociate strict manipulation from the validation of the results and from the consultant activity of the microbiologist. The choice criteria of the equipment are detailed as well as the experience of the LHUB-ULB bacteriological laboratory which was automated at the time of merging of the Brussels public hospital laboratories and developed a conclusive experience of tele-bacteriology for the peripheral lab.
Bax-inhibitor-1 knockdown phenotypes are suppressed by Buffy and exacerbate degeneration in a Drosophila model of Parkinson disease

BACKGROUND
Bax inhibitor-1 (BI-1) is an evolutionarily conserved cytoprotective transmembrane protein that acts as a suppressor of Bax-induced apoptosis by regulation of endoplasmic reticulum stress-induced cell death. We knocked down BI-1 in the sensitive dopa decarboxylase (Ddc) expressing neurons of Drosophila melanogaster to investigate its neuroprotective functions. We additionally sought to rescue the BI-1-induced phenotypes by co-expression with the pro-survival Buffy and determined the effect of BI-1 knockdown on the neurodegenerative α-synuclein-induced Parkinson disease (PD) model.


METHODS
We used organismal assays to assess longevity of the flies to determine the effect of the altered expression of BI-1 in the Ddc-Gal4-expressing neurons by employing two RNAi transgenic fly lines. We measured the locomotor ability of these RNAi lines by computing the climbing indices of the climbing ability and compared them to a control line that expresses the lacZ transgene. Finally, we performed biometric analysis of the developing eye, where we counted the number of ommatidia and calculated the area of ommatidial disruption.


RESULTS
The knockdown of BI-1 in these neurons was achieved under the direction of the Ddc-Gal4 transgene and resulted in shortened lifespan and precocious loss of locomotor ability. The co-expression of Buffy, the Drosophila anti-apoptotic Bcl-2 homologue, with BI-1-RNAi resulted in suppression of the reduced lifespan and impaired climbing ability. Expression of human α-synuclein in Drosophila dopaminergic neurons results in neuronal degeneration, accompanied by the age-dependent loss in climbing ability. We exploited this neurotoxic system to investigate possible BI-1 neuroprotective function. The co-expression of α-synuclein with BI-1-RNAi results in a slight decrease in lifespan coupled with an impairment in climbing ability. In supportive experiments, we employed the neuron-rich Drosophila compound eye to investigate subtle phenotypes that result from altered gene expression. The knockdown of BI-1 in the Drosophila developing eye under the direction of the GMR-Gal4 transgene results in reduced ommatidia number and increased disruption of the ommatidial array. Similarly, the co-expression of BI-1-RNAi with Buffy results in the suppression of the eye phenotypes. The expression of α-synuclein along with the knockdown of BI-1 resulted in reduction of ommatidia number and more disruption of the ommatidial array.


CONCLUSION
Knockdown of BI-1 in the dopaminergic neurons of Drosophila results in a shortened lifespan and premature loss in climbing ability, phenotypes that appear to be strongly associated with models of PD in Drosophila, and which are suppressed upon overexpression of Buffy and worsened by co-expression with α-synuclein. This suggests that BI-1 is neuroprotective and its knockdown can be counteracted by the overexpression of the pro-survival Bcl-2 homologue.
