Influence of experience and collaboration on effectiveness of quality management practices
Authors: Tripathi Deepak 
Published: January 2005

PurposeTo examine the impact of experience in terms of time period on TQM's effectiveness in improving performance of Indian manufacturing companies. To establish the impact of TPM support on TQM's effectiveness.Design/methodology/approachThis is an empirical research with testing of hypotheses using t tests. The data are collected with the help of a questionnaire on six performance parameters, which are measured on a five‐point scale. The study considers three time periods (phases) of implementation and two improvement strategies, i.e. TQM alone and TQM supported by TPM (combined strategy), for the purpose of analysis. The analysis is based on valid responses from 111 manufacturing companies.FindingsThe performance improvements contributed by TQM in the transition phase have been marginal due to initial investments and efforts required as well as to country‐specific factors. The effectiveness of TQM in the stability and maturity phases is established in an Indian context. The synergetic effect of TPM support on TQM's performance is also established in an Indian context.Practical implicationsThe paper establishes the long‐term effects of TQM on companies' performance in an Indian context. It also highlights various country‐specific factors, which led to marginal improvement during the transition phase. The paper also establishes that TQM with TPM support can be an effective strategy to improve competitiveness of Indian manufacturing companies.Originality/valueThis paper studies the two important factors which influence TQM's effectiveness. Although the study has been carried out in an Indian context, it is equally significant in a global scenario. This paper addresses a pertinent issue of simultaneous implementation of TQM and TPM, which is commonly found in industry but not adequately researched.

Published: January 2005

AbstractFood utilization by adults of the invasive maize (Zea mays L.) (Poaceae) pest western corn rootworm (WCR; Diabrotica virgifera virgifera LeConte) (Coleoptera: Chrysomelidae) was investigated in the south‐eastern part of its new European distribution range. At weekly intervals over a 10‐week period, 10 beetles per field were collected from six fields that had a high abundance of flowering weeds and six fields with a low abundance of flowering weeds, with the aim of understanding adult feeding behaviour in Europe and comparing this behaviour with North American WCR. Gut content analysis was performed to determine the use of maize tissue and weed pollen with regard to maize phenology. Furthermore, all pollen found within the gut was quantified and identified to plant species level. The use of maize tissue by adult WCR changed over time according to maize phenology. Pollen originating from plants other than maize was used more frequently as the maize matured. Adults fed on pollen from 19 of 25 different plant species found in maize fields and showed a preference for the pollen of specific weeds. Pollen from weed species was found more often in beetles from fields with a high abundance of weeds compared to beetles from fields with a low abundance of weeds. Females consumed greater amounts of pollen than males, the latter feeding on a wider diversity of host plants. The pollen resources used by adult WCR in Hungary were more diverse compared to WCR in the USA, which may contribute to the invasion success of WCR in Europe.

AbstractPheromone‐based mating disruption of lepidopteran pests (Tortricidae) of pome fruits using hand‐applied dispensing systems has become standard management practice for many producers in western North America. Sprayable microencapsulated (MEC) pheromone formulations that enable the application of pheromone controls with other orchard sprays and assist in the development of multispecies mating‐disruption systems are currently under development. Responses of male Choristoneura rosaceana (Harris) and Pandemis limitata (Robinson) (Lepidoptera: Tortricidae) to calling females in clean air, and air treated with their major pheromone component (Z)‐11‐tetradecenyl acetate (Z11‐14:OAc), released from a 3M sprayable pheromone formulation containing proprietary 3M Phase I microcapsules, applied at doses of 1, 10, and 100 mg of active ingredient (ai) m−2 to the upwind end of a flight tunnel (equivalent to field rates of 10, 100, and 1000 g ai ha−1) were compared in laboratory flight tunnels. In both species, disorientation was found to be dose‐dependent, because relative to male orientation to calling females in clean air, the orientation of male P. limitata was disrupted 23.3, 46.3, and 71.3%, and orientation by male C. rosaceana was disrupted 31.6, 37.7, and 45.8% by treatment doses of 1, 10, and 100 mg m−2, respectively. Latency of male responses to calling females in a background of Z11‐14:OAc relative to responses in clean air was also dose‐dependent. Albeit short, the disruption lasted 26, 74, and 218 h in P. limitata and 30, 54, and 174 h in C. rosaceana at each application rate, respectively. Disruption by pheromone treatment was greater in P. limitata than in C. rosaceana. This difference may be correlated with species’ differences in the pheromone release rates of females. Mechanisms of disruption invoked by this 3M MEC pheromone formulation are discussed in relation to issues of its longevity and observed differences in the effects against the two species. It appears possible to evaluate relative activity of MEC pheromones in a laboratory setting which may aid in development of new formulations for mating disruption.

Abstract:  Mitochondrial dysfunction might play a role in the pathogenesis of liver damage in erythropoietic protoporphyria (EPP). Changes in mitochondrial respiratory chain activities were evaluated in the Fechm1pas/Fechm1pas mouse model for EPP.Mice from different strains congenic for the same ferrochelatase germline mutation manifest variable degrees of hepatobiliary injury. Protoporphyric animals bred into the C57BL/6J background showed a higher degree of hepatomegaly and liver damage as well as higher protoporphyrin (PP) accumulation than those bred into the SJL/J and BALB/cJ backgrounds. Whereas mitochondrial respiratory chain activities remained unchanged in the liver of protoporphyric mice C57BL/6J, they were increased in protoporphyric mice from both SJL/J and BALB/cJ backgrounds, when compared to wild‐type animals. Mitochondrial respiratory chain activities were increased in Hep G2 cell line after accumulation of PP following addition of aminolevulinic acid. As a direct effect of these elevated mitochondrial activities, in both hepatic cells from mutant mouse strains and Hep G2 cells, adenosine 5′‐triphosphate (ATP) levels significantly increased as the intracellular PP concentration was reduced.These results indicate that PP modifies intracellular ATP requirements as well as hepatic mitochondrial respiratory chain enzymatic activities and further suggest that an increase of these activities may provide a certain degree of protection against liver damage in protoporphyric mice.

Published: January 2005

Aims : We present 51 cases of primary small cell carcinoma of the bladder in a clinicopathological study with emphasis on features that aid in the initial recognition and diagnosis of small cell carcinoma of the bladder.Methods and results : The patients were 40 men and 11 women between the ages of 39 and 87 years (mean age 67 years). Clinical data were available in 41 cases. The most common symptomatology was haematuria in 63% of the patients while dysuria was present in 12%. Thirty‐eight patients were caucasians; seven patients were Hispanics; two patients were Asian; one patient was African‐American; in the three additional patients no racial information was obtained. Biopsy material was obtained in all of the patients. Cystectomy was performed in 20 patients. At diagnosis, clinical stage was as follows: stage I in two (5%), stage II in 18 (44%), stage III in 10 (24%), and stage IV in 11 (27%). Histologically, urothelial carcinoma was present in 70% of the cases, adenocarcinoma in 8%, and squamous cell carcinoma in 10% of the cases. Small cell carcinoma was the only histology present in only 12% of the cases studied. Immunohistochemical studies using chromogranin, synaptophysin and chromogranin were positive in 30–70% of the cases.Conclusions : The present study highlights the unusual phenomenon of pure small cell carcinoma of the bladder and its association with other non‐small cell carcinomas in that anatomical location. In addition, the study highlights the different modalities employed to treat patients in whom there is a component of small cell carcinoma of the bladder.
Hypoxia‐inducible factor‐1α is associated with angiogenesis, and expression of bFGF, PDGF‐BB, and EGFR in invasive breast cancer

Published: January 2005

Aims : Hypoxia‐inducible factor‐1 (HIF‐1) is the key transcription factor regulating the cellular response to hypoxia, including angiogenesis. Growth factors play an important role in tumour growth and angiogenesis and some have been shown to be induced by HIF‐1 in vitro. This study investigated if angiogenesis or growth factors or their receptors are associated with HIF‐1α in invasive breast cancer.Methods and results : High levels of HIF‐1α, detected by immunohistochemistry in 45 breast cancers, were positively associated with increased microvessel density (as a measure of angiogenesis) (P = 0.023). Furthermore, high levels of HIF‐1α were associated with epithelial expression (≥ 10%) of epidermal growth factor receptor (EGFR) (P = 0.011), platelet‐derived growth factor (PDGF)‐BB (P < 0.001), and basic fibroblast growth factor (bFGF) (P = 0.045). A positive, yet insignificant, trend for HIF‐1α to be associated with epithelial expression of transforming growth factor (TGF)‐α (P = 0.081) and vascular endothelial growth factor (VEGF) (P = 0.109) was noticed as well as an inverse association with stromal expression of TGF‐β‐R1 (P = 0.070).Conclusions : In invasive breast cancer, HIF‐1α is associated with angiogenesis, and expression of growth factors bFGF and PDGF‐BB, and the receptor EGFR. Thus, agents targeting HIF‐1 may combine different pathways of inhibiting breast cancer growth, including angiogenesis and growth factors.
Transitional cell carcinoma of the bladder mimicking lobular carcinoma of the breast: a discohesive variant of urothelial carcinoma

Published: January 2005

Aims : To describe a series of 10 cases of transitional cell carcinoma which show morphological features which mimic lobular carcinoma of the breast and diffuse carcinoma of the stomach.Methods and results : Ten cases were identified from the files at Southampton University Hospitals NHS Trust and from the authors' consultation files. Immunostains were performed and clinical information was obtained. Eight of the patients were male and two female. Ages ranged from 52 to 77 years at presentation. All of the tumours showed areas where the tumour was composed of uniform cells with a discohesive single‐cell, diffusely invasive growth pattern. In areas the tumour cells were arranged in linear single‐cell files and in separate areas solid sheets of discohesive cells. In all of the cases some tumour cells showed prominent intracytoplasmic vacuoles. In addition to this pattern, four cases showed typical transitional cell carcinoma or carcinoma in situ. The majority of the tumours expressed cytokeratin 20 but not oestrogen receptors.Conclusion : This study highlights a pattern of diffusely invasive transitional cell carcinoma not previously described and one which is important to recognize in order to avoid misdiagnosis of metastatic lobular carcinoma of the breast, especially in small biopsies.

Marine introductions in the Shark Bay World Heritage Property, Western Australia: a preliminary assessment

Published: January 2005

ABSTRACTThe presence and impacts of non‐indigenous species (NIS) in marine areas of high conservation or World Heritage significance have rarely been examined. Case studies worldwide suggest that the potential exists for the introduction of NIS to significantly impact conservation values in regions conserved for the uniqueness and diversity of native assemblages. In this study, a preliminary investigation was conducted to provide information essential for managing marine introductions in the Shark Bay World Heritage Property. A focused fouling plate survey sampled a total of 112 encrusting taxa, of which 10 (11.2%) were classified as introduced and 10 others as cryptogenic. Eight introduced bryozoans: Aetea anguina (Linnaeus, 1758), Bugula neritina (Linnaeus, 1758), Bugula stolonifera Ryland, 1960, Conopeum seurati (Canu, 1928), Savignyella lafontii (Audouin, 1826), Schizoporella errata (Waters, 1878), Watersipora subtorquata (d’Orbigny, 1842) and Zoobotryon verticellatum della Chiaje, 1828; one tunicate, Styela plicata Lesueur, 1823; and an introduced hydroid, Obelia dichotoma (Linnaeus, 1758) were frequent, and in some cases dominant, components of encrusting communities. Of the 20 most frequently occurring species detected in the Bay, four were introduced and of the 20 species with highest average percent cover per plate, six were introduced. At one site, space occupation by NIS averaged 71.6% ± 7.4 of plate live cover. Space occupation by an individual NIS was as high as 62.4% of plate area (mean 7.82% ± 1.8). NIS were detected at sites lacking commercial traffic and ballast water discharge and isolated by distance and physical environment, suggesting that hull fouling of recreational craft may be the most important vector in the region. Seventy‐five percent of NIS detected in Shark Bay are established in Australian ports to the south of Shark Bay, while 33% are established to the north, tentatively implicating temperate affinity NIS and the movement of vessels from Australian ports south of Shark Bay as a greater risk to the region.

Published: January 2005

ABSTRACTWe examined the responses of a beetle assemblage to habitat complexity differences within a single habitat type, Sydney sandstone ridgetop woodland, using pitfall and flight‐intercept trapping. Six habitat characters (tree canopy cover, shrub canopy cover, ground herb cover, soil moisture, amount of leaf litter, and amount of logs, rocks and debris) were scored between 0 and 3 using ordinal scales to reflect habitat complexity at survey sites. Pitfall trapped beetles were more species rich and of different composition in high complexity sites, compared with low complexity sites. Species from the Staphylinidae (Aleocharinae sp. 1 and sp. 2), Carabidae (Pamborus alternansLatreille), Corticariidae (CartodereThomson sp. 1) and Anobiidae (MysticephalaFord sp. 1) were most clearly responsible for the compositional differences, preferring high complexity habitat. Affinities between general functional groupings of pitfall‐trapped beetles and habitat variables were not clear at a low taxonomic resolution (family level). The composition and species richness of flight‐intercept‐trapped beetles were similar in high and low complexity sites. Our study demonstrates that discrete responses of the various functional groups of beetles are strongly associated with their feeding habits, indicated by differing habitat components from within overall composite habitat complexity measures. Although habitat preferences by beetle species may often reflect their foraging habits, clarification of the causal mechanisms underpinning the relationships between habitat complexity and beetles are critical for the development of general principles linking habitat, functional roles and diversity.
Introduced invertebrates are important prey for a generalist predator

Published: January 2005

ABSTRACTConcern over biological invasions has drawn increased attention to the impacts of introduced predators or competitors, but not to the importance of introduced prey. North American forests are rich in introduced invertebrates, including species that represent relatively novel taxonomic or trophic guilds and show biased distributions among forest types. We analysed the diets of red‐backed salamanders,Plethodon cinereus, from three upland and three lowland forests to determine whether introduced prey are important contributors to geographical or temporal variation in salamander food resources. We found several introduced species were volumetrically important salamander prey, and were responsible for resource differences between forest types and much of the seasonal fluctuation in food resources in both forest types. In lowland forests, rain had a stronger effect on salamander predation on non‐native earthworms than native taxa, creating more dynamic resource fluctuations in resource levels than was observed in upland forests where earthworms were absent. With one exception, predation on non‐native species was positively associated with predation on native species, suggesting non‐native prey have added to salamander resources rather than replaced salamander predation on native taxa. We hypothesize that the novel resource gradients created by non‐native prey introductions are contributing to patterns of geographical and temporal phenotypic variation among salamander populations.
Bipolar II disorder: a review
Authors: Berk Michael , Dodd Seetal 
Published: January 2005

Objectives:  To review the current knowledge of bipolar II disorder.Methods:  Literature was reviewed after conducting a Medline search and a hand search of relevant literature.Results:  Bipolar II disorder is a common disorder, with a prevalence of approximately 3–5%. Distinct clinical features of bipolar II disorder have been described. The key to diagnosis is the recognition of past hypomania, while depression is the typical presenting feature of the illness. This is responsible for a significant rate of missed diagnosis, and consequent management according to unipolar guidelines. It is unclear if bipolar II disorder is over‐represented amongst resistant depression populations and if abrupt offset of antidepressant action is a phenomenon over represented in bipolar II disorder, reflecting induction of predominantly depressive cycling. A few mood‐stabilizer studies available provide provisional suggestion of utility. A supportive role for psychosocial therapies is suggested, however, there is a sparsity of published studies specific to bipolar II disorder cohorts. A small number of short‐term antidepressant trials have suggested efficacy, however, compelling long‐term maintenance data is absent.Conclusions:  An emerging literature on the specific clinical signature and management of the disorder exists, however, this is disproportionately small relative to the epidemiology and clinical significance of the disorder.
Neuropsychological deficits in adolescents with conduct disorder and comorbid bipolar disorder: a pilot study

Published: January 2005

Objective: We report pilot data on neuropsychological deficits in aggressive juvenile offenders with and without bipolar disorder compared with each other and healthy controls.Method: We assessed 52 adolescents and their parent or guardians: 36 incarcerated juvenile offenders and 16 community controls using the Schedule for Affective Disorders and Schizophrenia for School Age Children, Present and Life‐Time Version and a neuropsychological testing battery. All incarcerated subjects (n = 34) met criteria for Conduct Disorder (CD); 26 are classified as Non‐BD‐CD, and eight with CD and Bipolar disorder (CD‐BD). These subjects were compared to community controls (n = 16) matched for age, gender, SES and ethnicity.Results: Relative to controls, the Non‐BD‐CD subjects’ impairments (p < 0.05) were in cognitive ability, set shifting/inhibition, planning and verbal memory–language functioning. The CD‐BD group displayed impairments (p < 0.05) relative to controls in cognitive ability, set shifting, verbal memory–language functioning, and visuospatial tasks. The Non‐BD‐CD and CD‐BD groups however did not display significant differences on most neuropsychological measures compared with each other. When we controlled for Attention Deficit Hyperactivity Disorder, the Non‐CD‐BP subjects continued to show deficits on Verbal measures where the CD‐BD subjects maintained deficits in measures of cognitive ability, verbal measures and visual spatial tests.Conclusions: Juvenile offender with CD displayed a wide range of deficits on neuropsychological testing compared with controls. Although juvenile offenders with and without BD differed on their clinical presentation, differences on neuropsychological measures are not specific and may be related to comorbid diagnoses.
