Tensions between inclusion and change in worldview education: can Joe F. Kincheloe’s bricolage help teachers navigate them?

ABSTRACT This paper delineates tensions that arguably are inherent to integrative Worldview Education in plural societies, due to the subject’s dual commitment to imperatives of inclusion and change. The imperative of inclusion stems from the subject’s mandate to integrate the whole plurality of pupils in society, whereas the imperative of change stems from the subject’s mandate to promote certain aims and values over others. The task of handling such tensions can be daunting, and teachers need resources that enable them to do so. The main aim of this paper is thus to provide a critical examination of the metaphor of bricolage, as it was conceptualised by Joe L. Kincheloe, in search of such resources. The examination points to the following chain of argument: (1) Kincheloe’s bricolage contains its own tensions between inclusion and change, due to its application of multiple methods, methodologies, and perspectives, combined with a desire to promote social change. (2) There is a strong overlap between the two sets of tensions. (3) Teachers should be aware of the distinct political and philosophical underpinnings of Kincheloe’s bricolage, and how these can create new tensions, possibly productive ones, if teaching and learning in Worldview Education is framed as bricolage work.

Big Data Analytics for Crisis Management From an Information Processing Theory Perspective: A Multimethodological Study

COVID-19 pandemic has created disruptions and risks in global supply chains. Big data analytics (BDA) has emerged in recent years as a potential solution for provisioning predictive and pre-emptive information to companies in order to preplan and mitigate the impacts of such risks. The focus of this article is to gain insights into how BDA can help companies combat a crisis like COVID-19 via a multimethodological scientific study. The advent of a crisis like COVID-19 brings with it uncertainties, and information processing theory (IPT) provides a perspective on the ways to deal with such uncertainties. We use IPT, in conjunction with the Crisis Management Theory, to lay the foundation of the article. After establishing the theoretical basis, we conduct two surveys towards supply chain managers, one before and one after the onset of the COVID-19 pandemic in India. We follow it up with qualitative interviews to gain further insights. The application of multiple methods helps ensure the triangulation of results and, hence, enhances the research rigor. Our research finds that although the current adoption of BDA in the Indian industry has not grown to a statistically significant level, there are serious future plans for the industry to adopt BDA for crisis management. The interviews also highlight the current status of adoption and the growth of BDA in the Indian industry. The article interestingly identifies that the traditional barriers to implementing new technologies (like BDA for crisis management) are no longer present in the current times. The COVID-19 pandemic has hence accelerated technology adoption and at the same time uncovered some BDA implementation challenges in practice (e.g., a lack of data scientists).

Bienvenidos A Bordo: From Task-Based Needs Analysis to Design: Spanish-Destination Flight Attendants

The aim of this task-based needs analysis is two-fold: firstly, to uncover the tasks performed by U.S.-based Spanish-language flight attendants and the associated language needs and, in doing so, to expand the breadth of task-based needs analysis (TBNA) through the application of multiple methods and sources (Long, 2005) and tackling the under-researched issue of transfer from TBNA to task design (Gilabert & Malica, 2021a; 2021b). A questionnaire-guided interview and online survey were used. Analysis of the extracted information illuminated the essential tasks and subtasks (Gilabert, 2005), including details regarding frequency, need for training, and language use. Findings suggest that each task and subtask requires varying amounts of Spanish, as well as knowledge of distinct linguistic dimensions. Triangulation of multiple sources and methods adds to the understanding of the tasks and language needs. Finally, suggestions as to how the outcome of this NA may transfer to task design are presented, hence extending the field of TBNA.

Groundwater Recharge Estimation at Barind Area, Bangladesh for Sustainable Groundwater Management: Application of Multiple Methods

For proper management of groundwater resources, estimation of groundwater recharge is crucial. Information on groundwater recharge is particularly important in dry areas where groundwater is continuously depleting. In this study, groundwater recharge was estimated at two locations in the dry, Barind area of Bangladesh using the applied tracer, water balance (WB) and water-table fluctuation (WTF) methods. In the WTF method, considerations for drinking and irrigation withdrawal were taken. For runoff estimation in the WB method, a modified form of the USDA-SCS method was used. The results revealed that the average yearly recharge at the Nachol location varied from 104.9–195.8 mm/year under different methods, having a mean of 136.1 mm/yr over the methods. At Niamatpur location, the recharge rate varied from 125.1 to 210 mm (9.9 – 15.1% of yearly rainfall) under different methods, having a mean of 157.6 mm/yr. On average, the WTF method produced the lowest estimate of recharge followed by WB method. Based on the local geological and hydrological settings and the suitability/limitations of the methods themselves, the tracer technique may be regarded as a reliable method for the study area. The information on recharge will help the ‘water resource agency’ and ‘policymakers’ to adjust pumping/irrigation schemes, avoid over-exploitation of the groundwater resource, and ensure the long-term sustainability of the resource in the area.

Effects of polystyrene microplastics on copper toxicity to the protozoan Euglena gracilis: emphasis on different evaluation methods, photosynthesis, and metal accumulation.

Microplastics (MPs) released into aquatic environment interact with other pollutants that already exist in water, potentially altering their toxicity, which poses a new problem for aquatic ecosystems. In the present study, we first evaluated the effects of polystyrene MPs (mPS) on copper (Cu) toxicity to the protozoan Euglena gracilis using three methods based on 96-h acute toxicity, orthogonal test and 12-d sub-acute toxicity data. Thereafter, the 12-d sub-acute exposure was employed to investigate protozoan growth, photosynthetic parameters and pigments, soluble protein, total antioxidant capacity and trace metal accumulation in E. gracilis after exposure to either 1.5mg/L of Cu, 75-nm mPS (1 and 5mg/L) or a combination therein, with the objective to understand the underlined mechanisms. The results show that the concentration and exposure time are key factors influencing the effects of the mPS on Cu toxicity. A mPS concentration of 5mg/L caused significantly more dissipation energy, which is used for photosynthesis and thus decreased photosynthetic efficiency, but this effect weakened after 12 d of exposure. Exposure to Cu alone resulted in significantly high Cu accumulation in the cells and inhibited uptake of manganese and zinc. The presence of mPS did not influence the effects of Cu on trace metal accumulation. Our result suggests that application of multiple methods and indices could provide more information for a comprehensive understanding of the effects of mPS on toxicity of other pollutants. In addition, long-term exposure seems necessary for evaluating mPS toxicity.

Statistical methods for spatial cluster detection in childhood cancer incidence: A simulation study

Background and objectiveThe potential existence of spatial clusters in childhood cancer incidence is a debated topic. Identification of such clusters may help to better understand etiology and develop preventive strategies. We evaluated widely used statistical approaches to cluster detection in this context. MethodsIncidence of newly diagnosed childhood cancer (140/1,000,000 children under 15 years) and nephroblastoma (7/1,000,000) was simulated. Clusters of defined size (1–50) were randomly assembled on the district level in Germany. Each cluster was simulated with different relative risk levels (1–100). For each combination 2000 iterations were done. Simulated data was then analyzed by three local clustering tests: Besag-Newell method, spatial scan statistic and Bayesian Besag-York-Mollié with Integrated Nested Laplace Approximation approach. The operating characteristics (sensitivity, specificity, predictive values, power and correct classification) of all three methods were systematically described. ResultsPerformance varied considerably within and between methods, depending on the simulated setting. Sensitivity of all methods was positively associated with increasing size, incidence and RR of the high-risk area. Besag-York-Mollié showed highest specificity for minimally increased RR in most scenarios. The performance of all methods was lower in the nephroblastoma scenario compared with the scenario including all cancer cases. ConclusionThis study illustrates the challenge to make reliable inferences on the existence of spatial clusters based on single statistical approaches in childhood cancer. Application of multiple methods, ideally with known operating characteristics, and a critical discussion of the joint evidence seems recommendable when aiming to identify high-risk clusters.

Application of Multiple Methods of NDT for the Evaluation of Welded Joints in a Steel Bridge ASTM-A-588

This work is based on making a comparison of different inspection methods of non-destructive testing (NDT), to detect porosity, bite, undercut, splash, overlap, slag, concavity, lack of fusion and damage to base material, in welds of shielded metal arc welding (SMAW) and flux-cored arc welding (FCAW), made on a steel bridge ASTM-A-588. The main application of non-destructive tests is to evaluate the final state of a welded joint in critical points, in addition the fundamental objective is to ensure that the established acceptance and rejection criteria are met rigorously. For which non-destructive techniques are analyzed, such as the visual testing of welding on the beams of a bridge of length 35000 mm, subsequently, tests of inspection by liquid penetrant were used, based on the AWS D1.5 standard to confirm the failures in welded joints in ABA webs, an ultrasonic is also carried out using an SIUI CTS 602 equipment, finally to issue an acceptance and rejection criterion as determined by ASTM E165 and ASTM E2544-09.

Insights From a Multi-Method Recharge Estimation Comparison Study.

Although most recharge estimation studies apply multiple methods to identify the possible range in recharge values, many do not distinguish clearly enough between inherent uncertainty of the methods and other factors affecting the results. We investigated the additional value that can be gained from multi‐method recharge studies through insights into hydrogeological understanding, in addition to characterizing uncertainty. Nine separate groundwater recharge estimation methods, with a total of 17 variations, were applied at a shallow aquifer in northwest Ethiopia in the context of the potential for shallow groundwater resource development. These gave a wide range of recharge values from 45 to 814 mm/a. Critical assessment indicated that the results depended on what the recharge represents (actual, potential, minimum recharge or change in aquifer storage), and spatial and temporal scales, as well as uncertainties from application of each method. Important insights into the hydrogeological system were gained from this detailed analysis, which also confirmed that the range of values for actual recharge was reduced to around 280‐430 mm/a. This study demonstrates that even when assumptions behind methods are violated, as they often are to some degree especially when data are limited, valuable insights into the hydrogeological system can be gained from application of multiple methods.

Evaluation of removal of the size effect using data scaling and elliptic Fourier descriptors in otolith shape analysis, exemplified by the discrimination of two yellow croaker stocks along the Chinese coast

Removal of the length effect in otolith shape analysis for stock identification using length scaling is an important issue; however, few studies have attempted to investigate the effectiveness or weakness of this methodology in application. The aim of this study was to evaluate whether commonly used size scaling methods and normalized elliptic Fourier descriptors (NEFDs) could effectively remove the size effect of fish in stock discrimination. To achieve this goal, length groups from two known geographical stocks of yellow croaker, Larimichthys polyactis, along the Chinese coast (five groups from the Changjiang River estuary of the East China Sea and three groups from the Bohai Sea) were subjected to otolith shape analysis. The results indicated that the variation of otolith shape caused by intra-stock fish length might exceed that due to inter-stock geographical separation, even when otolith shape variables are standardized with length scaling methods. This variation could easily result in misleading stock discrimination through otolith shape analysis. Therefore, conclusions about fish stock structure should be carefully drawn from otolith shape analysis because the observed discrimination may primarily be due to length effects, rather than differences among stocks. The application of multiple methods, such as otoliths shape analysis combined with elemental fingering, tagging or genetic analysis, is recommended for sock identification.

Telemetry reveals spatial separation of co-occurring reef sharks

The ability to understand the functioning of ecosystems requires an understanding of the role individual or groups of species play within that environment. Defining ecological roles is challenging in complex ecosystems such as coral reefs. While it is well known that multiple reef-associated shark species coexist on a single reef, their patterns of space use and interactions have been difficult to define. Here we used acoustic telemetry data to analyse activity space, depth use and spatial networks to examine the interplay of these species relative to their roles in coral reef ecosystems. Integration of multiple analyses revealed that species with similar sizes and similar diets displayed clear spatial segregation, both between habitats and depth. This distribution is likely to reduce competition for prey among these species. In contrast, species that are dietary generalists or that have unique diets moved more broadly and overlapped with all other species. These results suggest competition for prey may be a driving factor in the distribution and space use of reef-associated sharks, revealing complex, interdependent functional roles within these systems. Results of this analysis demonstrate the advanced information that can be obtained through application of multiple methods and directed, simultaneous study of multiple species.

Application of multiple methods in puncture fluid examination for diagnosis of axillary cystic/solid mass

The clinical data of 91 patients with axillary cystic/solid mass receiving ultrasound-guided mass puncture in Hangzhou Red Cross Hospital and Hangzhou Third Hospital from March 2010 to October 2015 were retrospectively analyzed. The biopsy cytology examination and routain bacteria culture of puncture fluid were applied in 44 cases (control group); while X-pert examination of puncture fluid was performed in addition to biopsy cytology examination and routain bacteria culture in 47 cases (study group). The histopathological examination of surgical specimens were used as gold standard. The overall diagnostic accuracy rates of study and control groups were 93.6% (44/47) and 68.2% (30/44), respectively(P=0.002). The diagnostic accuracy rates for tuberculous abscess in study and control groups were 100.0%(28/28)and 57.7%(15/26), respectively (P=0.000). However, there were no significant differences in diagnosis of other diseases, including metastatic carcinoma, abscess other than tuberculous and lymphatic hygroma between two groups. The study shows that diagnostic accuracy of multiple examination methods of puncture fluid for axillary cystic/solid mass is high and has clinical application value. Key words: Biopsy, needle; X-pert exam; Cystic and solid mass

Secondary expansion of the transient subplate zone in the developing cerebrum of human and nonhuman primates

The subplate (SP) was the last cellular compartment added to the Boulder Committee's list of transient embryonic zones [Bystron I, Blakemore C, Rakic P (2008) Nature Rev Neurosci 9(2):110-122]. It is highly developed in human and nonhuman primates, but its origin, mode, and dynamics of development, resolution, and eventual extinction are not well understood because human postmortem tissue offers only static descriptive data, and mice cannot serve as an adequate experimental model for the distinct regional differences in primates. Here, we take advantage of the large and slowly developing SP in macaque monkey to examine the origin, settling pattern, and subsequent dispersion of the SP neurons in primates. Monkey embryos exposed to the radioactive DNA replication marker tritiated thymidine ([(3)H]dT, or TdR) at early embryonic ages were killed at different intervals postinjection to follow postmitotic cells' positional changes. As expected in primates, most SP neurons generated in the ventricular zone initially migrate radially, together with prospective layer 6 neurons. Surprisingly, mostly during midgestation, SP cells become secondarily displaced and widespread into the expanding SP zone, which becomes particularly wide subjacent to the association cortical areas and underneath the summit of its folia. We found that invasion of monoamine, basal forebrain, thalamocortical, and corticocortical axons is mainly responsible for this region-dependent passive dispersion of the SP cells. Histologic and immunohistochemical comparison with the human SP at corresponding fetal ages indicates that the same developmental events occur in both primate species.

Subjective elements in climate policy advice

Subjective elements are an inevitable component of scientific advice on climate policies. Good practice warrants that the level of assumption underlying subjective elements be parsimonious, that their effects on policy decisions be identified, and that policy relevant variables be communicated with appropriate levels of precision. In the case of climate sensitivity, the level of precision is intrinsically difficult to quantify. There is no ‘true’ value of climate sensitivity to be discovered. Rather, best practice consists of the application of multiple methods to estimate the quantity. Best practice provides confidence that some values of climate sensitivity are more likely than others. This lends support to the notion of weighting climate sensitivity values, though the appropriate precision appears to be less than that implied by use of a probability density function (pdf) and greater than that implied by use of a simple range. Use of both a pdf and a range in this case can provide information about likely outcomes and possible extremes.

Carbon balance assessment of a natural steppe of southern Siberia by multiple constraint approach

Abstract. Steppe ecosystems represent an interesting case in which the assessment of carbon balance may be performed through a cross validation of the eddy covariance measurements against ecological inventory estimates of carbon exchanges (Ehman et al., 2002; Curtis et al., 2002). Indeed, the widespread presence of ideal conditions for the applicability of the eddy covariance technique, as vast and homogeneous grass vegetation cover over flat terrains (Baldocchi, 2003), make steppes a suitable ground to ensure a constrain to flux estimates with independent methodological approaches. We report about the analysis of the carbon cycle of a true steppe ecosystem in southern Siberia during the growing season of 2004 in the framework of the TCOS-Siberia project activities performed by continuous monitoring of CO2 fluxes at ecosystem scale by the eddy covariance method, fortnightly samplings of phytomass, and ingrowth cores extractions for NPP assessment, and weekly measurements of heterotrophic component of soil CO2 effluxes obtained by an experiment of root exclusion. The carbon balance of the monitored natural steppe was, according to micrometeorological measurements, a sink of carbon of 151.7±36.9 g C m−2, cumulated during the growing season from May to September. This result was in agreement with the independent estimate through ecological inventory which yielded a sink of 150.1 g C m−2 although this method was characterized by a large uncertainty (±130%) considering the 95% confidence interval of the estimate. Uncertainties in belowground process estimates account for a large part of the error. Thus, in particular efforts to better quantify the dynamics of root biomass (growth and turnover) have to be undertaken in order to reduce the uncertainties in the assessment of NPP. This assessment should be preferably based on the application of multiple methods, each one characterized by its own merits and flaws.

River sedimentation and fluvial response to Holocene environmental change in the Yorkshire Ouse Basin, northern England

Holocene alluvial sediment sequences and floodplain geomorphological histories from three valley-floor sequences in the Yorkshire Ouse Basin have been determined using a variety of field evidence and laboratory methods: geomorphological mapping, sediment coring and trenching, physical and chemical analysis of sedimentary units, and 14C dating. The application of multiple methods has revealed contrasting phases of river erosion, alluviation and depositional styles during the Late Quaternary at each of the individual study reaches. The gravel bedded River Swale at Catterick has been characterized by progressive valley-floor incision during the late Holocene with major phases of incision occurring during the cooler and wetter phase of the 'Little Ice Age’. Within the last c. 245 years, substantial thicknesses (up to 2 m) of overbank alluvium contaminated by metalliferous mining have been deposited across thefloodplain. In contrast, floodplain development in the lower reaches of the River Swale at Myton and the River Aire at Beal has predominantly been one of relative channel stability and vertical aggradation. Here, low floodplain gradients, wide valley floors, stable channels and limited lateral floodplain erosion have combined to produce thick (c.10 m) sequences of finegrained alluvium deposited in overbank environments. Mining-related contamination in lowland floodplains is much lower than at Catterick with limited amounts of historically contaminated alluvium being deposited across the floodplain. Although environmental change has been important in controlling Holocene floodplain development, the upper and lower reaches of the Yorkshire Ouse basin have responded differently to these effects because of reach-scale geomorphic controls. Caution needs to be applied before relating broad-scale environmental change to river response across a whole river basin.
