The locus effect on inertia equity
Authors: Ye Gewei 
Published: June 2005

PurposeThe paper attempts to answer “Will the shift from the locus of self to locus of others impact the magnitude of loss aversion?” and “Will different prices affect the self‐other asymmetry in choice?”.Design/methodology/approachThe design is a two (locus: self vs others) by two (anchoring price: $30 vs $90) between‐subjects’ factorial with both the locus of evaluation and the monthly service plan charges (anchoring prices) as the between‐subjects’ factors.FindingsThe author finds that inertia equity is smaller when consumers evaluate peer customers than when they evaluate themselves to switch brands. It is also found that the locus effect is applicable to brands at various prices.Research limitations/implicationsFurther research should focus on the validations of the assumptions to support the empirical finding from the theoretical perspective.Practical implicationsPrice reductions should be made personally relevant to the consumer and price increases should be made relevant to other things.Originality/valueThe locus effect expands the assessment of loss aversion from one (self or other) to two dimensions jointly (self and other). It demonstrates the impact of the locus of evaluation on the magnitude of loss aversion.

Authors: Hoe‐Lian Goh Dion , Fu Lin , Shou‐Boon Foo Schubert 
Published: June 2005

PurposeInformation overload has led to a situation where users are swamped with too much information, resulting in difficulty sifting through material in search of relevant content. Aims to address this issue from the perspective of collaborative querying, an approach that helps users formulate queries by harnessing the collective knowledge of other searchers.Design/methodology/approachThe design and implementation of the Query Graph Visualizer (QGV), a collaborative querying system which harvests and clusters previously issued queries to form query networks that represent related information needs are described. A preliminary evaluation of the QGV is also described in which a group of participants evaluated the usability and usefulness of the system by completing a set of tasks and a questionnaire based on Nielsen's heuristic evaluation technique.FindingsIn the QGV, a submitted query is matched to its closest cluster and a recursive algorithm is applied to find other related clusters, forming a query network. The queries in the network are explored in the QGV, helping users locate other queries that might meet their current information needs. The results of the evaluation suggest the usefulness and usability of the system. Participants could complete their assigned tasks using the QGV and positively rated the system in terms of usability.Originality/valueThe techniques described can be used to design information retrieval systems that learn from the trials and tribulations of other searchers and help users in their quest for relevant and quality information

Dynamic cellular manufacturing under multiperiod planning horizons
Authors: Balakrishnan Jaydeep , Hung Cheng Chun 
Published: June 2005

PurposeThe purpose of this research paper is to discuss cellular manufacturing is discussed under conditions of changing product demand. Traditional cell formation procedures ignore any changes in demand over time from product redesign and other factors. However given that in today's business environment, product life cycles are short, a framework is proposed that creates a multi‐period cellular layout plan including cell redesign where appropriate.Design/methodology/approachThe framework is illustrated using a two‐stage procedure based on the generalized machine assignment problem and dynamic programming. This framework is conceptually compared to virtual cell manufacturing, which is useful when there is uncertainty in demand rather than anticipated changes in demand. A case study is used to explain how the concept would work in practice.FindingsOne major characteristic of the proposed method is that it is flexible enough to incorporate existing cell formation procedures. It is shown through an example problem that the proposed two‐stage method is better than undergoing ad hoc layout changes or ignoring the demand changes when shifting or cell rearrangement costs exist. It also sheds some insight into cellular manufacturing under dynamic conditions.Originality/valueThis paper should be useful to both researchers and practitioners who deal with demand changes in cellular manufacturing.
Integrating six sigma and theory of constraints for continuous improvement: a case study
Authors: Ehie Ike , Sheu Chwen 
Published: June 2005

PurposeTo investigate the potential of combining six sigma (SS) and theory of constraints (TOC) to improve production system performance.Design/methodology/approachBased on the literature, this paper proposes an integrated TOC/SS framework and applies this framework to an axle manufacturing company to improve its gear‐cutting operation.FindingsThe results of the case study indicate that the company benefited tremendously from its emphasis on global improvement guided by the TOC concept. Managers were able to select a continuous improvement (CI) project that had greater impact on bottom line performance. On the other hand, SS provided various statistical tools and engineering techniques (such as value analysis, Pareto diagram and control charts) for defining the specific process to be improved, analyzing the root causes, and designing actions for making improvement.Research limitations/implicationsFor the future effort of integrating TOC with SS and other CI techniques, we suggest the incorporation of a TOC methodology, thinking process (TP).Practical implicationsOverall, the integration of SS and TOC provides managers with an excellent platform for two CI techniques to work together and create great synergy.Originality/valueThis study adds to the CI literature and practice by demonstrating the value of a method of combining TOC and SS.

Published: June 2005

Abstract.   Circadian variation in cell proliferation of the jejunal epithelium of 18‐day‐old rats was studied using the 2‐h arrested metaphase score and crypt isolation method. A continuous decrease in the arrested metaphases occurred from 07.00 h to13.00 h. From 17.00 h arrested metaphase values increased and were maintained at the higher level during the dark period as showed by Cosinor analyses (P < 0.05). These results indicate that in the young rat there is already a circadian variation in jejunal epithelial cell proliferation as early as 18 days. We can even suggest that the presence of a circadian rhythm at weaning contributes to the steady state of cell proliferation in the intestinal epithelium observed in adult life.
Effects of ultra‐wideband electromagnetic pulses on pre‐neoplastic mammary epithelial cell proliferation

Published: June 2005

Abstract.  Electromagnetic ultra‐wideband pulses (UWB) or nanopulses, are generated by a wide range of electronic devices used in communications and radar technology. However, the specific effects of nanopulse exposure on cell growth and function have not been extensively investigated. Here, studies have been conducted to determine the effects of prolonged exposure to non‐ionizing, low to moderate intensity nanopulses on the growth of pre‐neoplastic CL‐S1 mammary epithelial cellsin vitro. Cells were grown in culture and maintained in serum‐free defined medium containing 10 ng/ml EGF and 10 µg/ml insulin as comitogens. Studies showed that 0.25–3.0 h exposure to nanopulses of 18 kV/m field intensity, 1 kHz repetition rate and 10 ns pulse width had no effect on CL‐S1 cell growth or viability during the subsequent 72‐h culture period. However, exposure to similar nanopulses for prolonged periods of time (4–6 h) resulted in a significant increase in cell proliferation, as compared to untreated controls. Additional studies showed that nanopulse exposure enhanced CL‐S1 cell growth when cells were maintained in media containing only EGF, but had no effect on cells maintained in defined media that were mitogen‐free or containing only insulin. Studies also showed that the growth‐promoting effects of nanopulse exposure were associated with a relatively large increase in intracellular levels of phospho‐MEK1 (active) and phospho‐ERK1/2 (active) in these cells. These findings demonstrate that prolonged exposure to moderate levels of UWB enhanced EGF‐dependent mitogenesis, and that this growth‐promoting effect appears to be mediated by enhanced activation of the mitogen‐activated protein kinase (MAPK) signalling pathway in pre‐neoplastic CL‐S1 mammary epithelial cells.

AbstractBackground  Mycosis fungoides (MF) and Sezary syndrome (SS) are the most common forms of cutaneous T‐cell lymphoma (CTCL). Various topical and systemic therapeutic alternatives are available, but there is no standard or definite curative treatment regimen. When making a decision about the appropriate treatment modality, the age and compliance of the patient, stage of the disease, treatment accessibility, and previous treatment history should be considered.Aim  To determine the therapeutic response of patients with MF and SS to different treatment modalities. Patients were evaluated with respect to their clinical and demographic features.Methods  One hundred and thirteen patients diagnosed clinically and dermatopathologically with MF and SS between March 1984 and June 2001 were included in the study.Results  Of the 113 patients studied, 110 had a diagnosis of MF and three had a diagnosis of SS; 101 patients (89.4%) were diagnosed with early stage (IA, IB, IIA) and 12 (10.6%) with late stage (IIB, III, IVA, IVB) disease. The age at diagnosis varied between 12 and 81 years (mean, 45.6 ± 15.8 years). Fifty‐five (48.7%) patients were male and 58 (51.3%) were female. The duration of the skin lesions varied between 1.5 months and 32 years (mean, 6.1 years). Psoralen plus UVA (PUVA) was the most commonly used initial treatment modality in early stage disease (91%), with a complete remission (CR) rate of 80.4%. With PUVA + interferon‐α (INF‐α) treatment, CR was 57% in the early stages and 33.3% in the late stages. For late stage disease, systemic therapies, such as pentostatin, gemcitabine, and fludarabine, alone or in combination with INF‐α, were preferred. Of the 113 patients, eight (7% of the total and 57.1% of the advanced stage cases) died of MF; 21.4% of the late stage patients showed partial remission and 14.2% showed CR. None of the patients diagnosed with early stage disease died of MF, but two (1.9%) progressed to late stage disease.Conclusions  PUVA and PUVA + INF‐α are effective treatment modalities, especially for early stage MF. Once the disease has progressed, both MF and SS are very resistant to treatment regimens, including chemotherapeutic agents. It is important to diagnose and treat these diseases, especially MF, in the early stages for lasting remission.

A 55‐year‐old male dairy farmer was admitted to our hospital with a skin infection on the neck and face. He was apparently in good general health, and his medical history was unremarkable. He reported that, 50 days before admission, a pruritic red maculopapular rash had developed on the anterior region of his neck. This rash failed to improve after a 10‐day course of trimethoprim‐sufamethoxazole and fluconazole; rather it progressively worsened. On admission, examination revealed confluent follicular papulae‐pustules with purulent‐hematic exudation and crusting, on an erythematous‐edematous area extending over the anterior region of the neck, chin and mandible (Fig. 1); hairs within the affected area were not compromised. Body temperature was 38.5 °C, and cervical nodes were not appreciable. Results of routine laboratory investigations were: white blood cells (WBC), 8090/mm3 (85% neutrophils, 10% lymphocytes and 4% monocytes); erythrocyte sedimentation rate, 72 mm/h; C‐reactive protein, 44.8 mg/100 mL; serum glucose, 453 mg/100 mL. Quantitative measurements of serum levels of immunoglobulins M, G, A, and E, total complement activity, complement factors C3 and C4, and alpha‐1‐antitrypsin were within normal limits.Coalescent follicular papulae‐pustules with purulent‐hematic exudation and crusting, on an erythematous‐edematous area involving the face and neck of a dairy farmerimageSwabs for bacteriological and mycological analysis were taken from pustules. While waiting for the results of the cultures, insulin therapy was started at 40 IU/day, because of hyperglycemia. Mycological culture was negative, while bacteriological culture yielded Klebsiella oxitoca. The patient was treated with ceftazidime 4 g/day intravenously and amikacin 1 g/day intramuscularly for 3 weeks, and a slow and progressive improvement, with no formation of scars or alopecic areas, was observed (Fig. 2).Appearance of the previously involved area after a 3‐week course of ceftazidime and amikacin.

Published: June 2005

AbstractBackground  Ciclopirox is an antifungal agent and is effective against both Gram‐positive and Gram‐negative bacteria. These properties may give ciclopirox an advantage over other antifungal agents in the treatment of interdigital tinea pedis with secondary bacterial infection (dermatophytosis complex).Objective  To evaluate the efficacy of ciclopirox 0.77% gel in the treatment of tinea pedis interdigitalis with secondary bacterial infection in a prospective, randomized, double‐blind, placebo‐controlled clinical study.Subjects and methods  One hundred subjects were enrolled in this 8‐week study (twice‐daily ciclopirox, 40 subjects; once‐daily ciclopirox, 40 subjects; twice‐daily vehicle, 20 subjects). Mycologic sampling, bacterial swabs, and evaluations for symptoms and signs of tinea pedis were performed on a target webspace at baseline and at weeks 2, 4, and 8. Global evaluations were made by both investigator and subject at each visit.Results  Ciclopirox gel applied once or twice daily significantly reduced the signs and symptoms at week 8, compared with vehicle (P < 0.0036). The mycologic cure and complete cure rates were much higher for the ciclopirox regimens than for the vehicle regimen. Early reduction of bacterial counts was noted with the ciclopirox regimens. There was no significant difference in the adverse event rate between the ciclopirox groups and the placebo group.Conclusion  Ciclopirox 0.77% gel, applied once or twice daily, is effective and safe in the treatment of tinea pedis interdigitalis with concomitant bacterial infection (dermatophytosis complex).

LeVasseur SA, Fitzgerald R, Bell F. International Journal of Nursing Practice 1998; 4: 33–39 A descriptive study examining postdischarge patient needs after laser ablation and transuretheral resection of the prostate This descriptive study identifies and describes the postdischarge experiences in two groups of patients with benign prostate hyperplasia. The two patient groups included 12 patients who underwent laser ablation and 12 patients who underwent traditional transuretheral prostatectomy. A questionnaire was developed and used to examine the postoperative experiences of the two groups after discharge. The questionnaire obtained demographic information from medical records and examined the types of assistance required at home, the need to contact health professionals, difficulties encountered after catheter removal and the amount of time until resolution of symptoms and a return to normal activities. The laser ablation group were discharged home with an indwelling catheter, and thus were required to complete additional questions regarding their experiences of going home with a catheter and leg bag.The results indicate the laser ablation group went home with an indwelling catheter and reported a higher frequency of symptom distress and technical problems in caring for the leg bag. The laser ablation group also sought more assistance from health professionals. These problems were not demonstrated in the traditional transuretheral prostatectomy group, who remained in hospital until the catheter was removed. This study demonstrates the need for further nursing research examining patient issues that occur during the postdischarge recovery phase.
Restoring homeostasis in a residential care facility through behaviour modification

Published: June 2005

Wilson SJ & Barrett CM. International Journal of Nursing Practice 1998; 4: 51–57 Restoring homeostasis in a residential care facility through behaviour modification A verbally aggressive, 32‐year‐old male with a traumatic brain injury was admitted to a unit in an aged care facility for residential care. The homeostasis of the unit was disrupted by the resident's verbal aggression and other inappropriate behaviours. With the guidance of a neuropsychologist, nursing staff were able to use behaviour modification to successfully replace the disruptive behaviours with more socially appropriate ones. A series of positive rewards was implemented in response to socially appropriate behaviour, whilst inappropriate behaviours received a negative reward. Several disruptive behaviours were affected by the single treatment implemented. This interdependence of targeted behaviours was viewed as a clinical advantage, as it served to provide a more rapid restoration of homeostasis to the unit. The use of a single‐subject, multiple baseline design in this case study demonstrates that disruptive behaviours may be reversible.

Abstract  Aim:  The information currently available suggests that nonadrenergic noncholinergic (NANC) transmitters, particularly nitric oxide, are involved in the relaxation of penile erectile tissues. Platelet‐activating factor (PAF) is a chemical mediator and is involved in many physiological and pathophysiological events. It is well known that several of the vascular actions of PAF are mediated by the generation of nitric oxide. We designed this study to test the hypothesis that PAF has an effect on NANC responses in rabbit corpus cavernosum strips.Methods:  Rabbit corpus cavernosum strips were precontracted with phenylephrine (10−5 mol/L). Isometric  tension  changes  produced  by  carbachol (10−9−10−5 mol/L), sodium nitroprusside (10−8−10−5 mol/L) and electrical field stimulation (for 10 s at sequential frequencies of 2, 4, 8, 16, and 32 Hz as square‐wave pulses of 50 mV) were recorded with a pressure transducer. These relaxations were compared to those obtained in the presence of PAF.Results:  PAF had no effect on endothelium‐dependent, endothelium‐independent or electrical field stimulation‐induced NANC relaxation responses in isolated rabbit corpus cavernosum strips. There was no statistically significant difference between the pD2 and Emax values for carbachol or sodium nitroprusside in the presence of PAF.Conclusions:  Our results suggest that PAF does not modify the endothelium‐dependent, endothelium‐independent or electrical field stimulation‐induced NANC relaxation responses in isolated rabbit corpus cavernosum strips.

AbstractSPOT 5 HRG Level 1A and 1B stereo scenes covering Zonguldak testfield in north‐west Turkey have been analysed. They comprise the left and right image components with base to height ratio of 0·54. The pixel size on the ground is 5 m. The bundle orientation was executed by the PCI Geomatica V9.1.4 software package and resulted in 3D geopositioning to sub‐pixel accuracies in each axis provided that at least six control points were used in the computation. Root mean square error (rmse) values and vectors of residual errors for Levels 1A and 1B are similar, even for different control and check point configurations. Based on the scene orientation, Level 1A and 1B digital elevation models (DEMs) of the testfield have been determined by automatic matching and validated by the reference DEM digitised from the 1:25 000 scale topographic maps, interferometric DEMs from Shuttle Radar Topography Mission (SRTM) X‐ and C‐band SAR data and the GPS profiles measured along the main roads in the testfield. Although the accuracies of reference data‐sets are too similar to the generated SPOT DEMs, these are the only high quality reference materials available in this area. Sub‐pixel height accuracy was indicated by the comparison with profile points. However, they are in favourable locations where matching is always successful, so such a result may give a biased measure of the accuracy of the corresponding DEMs.
Time‐Series Data and the “Migraine Generator”
Authors: Fox Anthony W. 
Published: June 2005

Objective.—To examine circadian and menstrual patterns of migraine frequency in order to identify properties of the putative migraine generator.Methods.—Analysis of circadian and menstrual migraine attack frequency distributions, using between‐interval differences as estimates, at each time point, of the derivative of the equation that would, theoretically, model the observed oscillating functions.Results.—Circadian and menstrual analyses exhibit many similarities that are consistent with a single migraine generator in the final common pathway for expression of the phenotype. These analyses are inconsistent with a role for cortisol or ACTH to be activators of the putative migraine generator, could be consistent with visual stimulation as a deactivator of the generator, and may also be consistent with a low threshold concentration of estradiol and/or progestagens as inactivators of the migraine generator.Conclusions.—Analysis of time‐series data using differentials uncovers some previously unidentified chronobiological properties of migraine, helps select amongst various candidate provocative factors, and suggests some properties of a putative migraine generator.
