This chapter studies the way language policies are interpreted, with particular reference to the concepts of scale and recontextualisation. The focus of the chapter is on the relationship between policy meaning and power, with the main argument being that different layers of power are what drives the way language policies are interpreted in different contexts. This is illustrated with a discussion of the Common European Framework of Reference for Languages (CEFR), a policy text which has seen worldwide uptake. I examine how the document is ‘read’ in different contexts, considering the local and global layers of power that lurk beneath these readings.
Scalar inferences (SIs) are upper-bounding inferences associated with the use of semantically lower-bounded scalar expressions. One of the current debates regarding these inferences concerns their inferential pattern, specifically whether SIs are uniform or diverse across scales. This study follows the work on scalar diversity yet introduces two changes: First, we reexamine, from a different perspective, two structural properties of scales identified as accounting for SI diversity (boundedness and distance). Second, we analyze our data using both traditional regression analysis and complementary cluster analysis. The regression analysis demonstrates that our reexamination of the structural properties provides a more effective model, which also emphasizes the relationship between boundedness and distance. Specifically, we propose that boundedness fixes distance. The cluster analysis demonstrates two scale types: given-scales, which have an entrenched scalar construal, trigger SIs robustly; and volatile-scales, which have a fluctuant scalar construal, trigger SIs inconsistently. Building on these two scale types, we propose a necessary distinction between the conceptualization of a scale, which is diverse across different scales, and the actual derivation of the SI, which is uniform for all scales, once a scale has been construed. This distinction, we propose, explains how diversity can coexist alongside uniformity.
Focusing on the late prehistoric southern Levant, we recently suggested that the diffused low-frequency distribution of large predator bones (lion, leopard and bear) coalesces into a coherent temporal pattern when observed at a sufficiently long timescale. While in the previous research we sought to determine what sort of sociocultural mechanism might explain this pattern, effectively drawing it into the orbit of the familiar, in this brief provocation, we push in the other direction, towards the unfamiliar: how can a process or phenomenon be culturally significant yet meaningless at the human and societal levels? How is a phenomenon substantial in the long term and insubstantial in the short term?
There is no universal tool for measuring disaster preparedness in the general population. This study aimed to provide a summary of the domains and psychometric properties of the available scales that assess preparedness for disasters, or one of its main types, among individuals or households.
Methods:
This study is a systematic review of the literature on disaster preparedness tools. Studies published up to December 2022 were identified through a systematic search of four databases: Google Scholar, PubMed, Scopus, and Web of Science. Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) were used to review and evaluate the psychometric properties. The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were used to report this article.
Results:
Twelve articles met the inclusion criteria. Among them, five scales measured general disaster preparedness, five measured earthquake preparedness, one measured flood preparedness, and one measured bushfire preparedness. The scales had a number of dimensions ranging from one to six. The most common item topics in the included scales were as follows: having an evacuation plan (n = 7), information source (n = 7), fire extinguisher (n = 6), and emergency kit (n = 5). The scales were rated sufficient for content validity (n = 10), structural validity (n = 5), internal consistency (n = 5), and test-re-test reliability (n = 6). One scale was checked for criterion validity and was rated as insufficient according to the COSMIN guidelines.
Conclusion:
The findings suggest the need to improve the psychometric properties of the scales, expand their contents, and develop scales relevant to target populations. This study provides useful information for researchers to develop comprehensive assessment tools and valuable sources of items for future scales.
Permian fishes and their isolated microremains are known from many localities in the Zechstein Basin. However, up to date the vertebrates have never been revealed in the southeasternmost part of this ancient sea. The new material consists of euselachian-type dermal denticles,?Listracanthus sp. dermal denticle,?Omanoselache sp. tooth, actinopterygian scales and actinopterygian teeth. Here, the detailed study of euselachian and actinopterygian remains, their stratigraphic distribution and geographical contexts is presented. Based on the qualitative analysis of teeth shapes several ecomorphotypes were described as well as the probable dietary preferences of fishes were reconstructed. These finds confirmed existence of small predators who fed on soft bodied prey as well as durophagous forms which were feeding on small shelly crustaceans or molluscs. The analysis of stratigraphic distribution of microremains, and their comparison with neighbouring sections revealed a spatially correlatable trend in increasing abundance of fishes in the more clayey parts of sections, interpreted to be positively associated with a sea level transgression event.
This chapter is the most crucial part of the book, the fundamental building block of the concept of dispersion in porous media and macrodispersion in the field-scale aquifers. It unravels the myth of macrodispersion, anomalous dispersion, scale-dependent dispersion, dual-domain, and other recently developed dispersion models for solute transport in aquifers (Chapters 9 and 10). This chapter first explains how the concept of dispersion evolves from molecular diffusion to account for the effects of fluid-dynamics-scale velocity variation in solute migration in a pipe. The relationship between dispersion and the concentration averaged over the cross-section of a pipe is visited. Further, this chapter illustrates the molecular and fluid-dynamics-scale velocity variations, the interaction between diffusion and dispersion, and scale issues associated with the shear flow dispersion. Finally, it discusses the limitations of extending Fick’s law for molecular-scale velocity variations to describe the effects of fluid-dynamics-scale velocity variations.
Over the past several decades, analyses of solute migration in aquifers have widely adopted the classical advection-dispersion equation. However, misunderstandings over advection-dispersion concepts, their relationship with the scales of heterogeneity, our observation and interest, and their ensemble mean nature have created furious debates about the concepts' validity. This book provides a unified and comprehensive overview and lucid explanations of the stochastic nature of solute transport processes at different scales. It also presents tools for analyzing solute transport and its uncertainty to meet our needs at different scales. Easy-to-understand physical explanations without complex mathematics make this book an invaluable resource for students, researchers, and professionals performing groundwater quality evaluations, management, and remediation.
Assume $\mathsf {ZF} + \mathsf {AD}$ and all sets of reals are Suslin. Let $\Gamma $ be a pointclass closed under $\wedge $, $\vee $, $\forall ^{\mathbb {R}}$, continuous substitution, and has the scale property. Let $\kappa = \delta (\Gamma )$ be the supremum of the length of prewellorderings on $\mathbb {R}$ which belong to $\Delta = \Gamma \cap \check \Gamma $. Let $\mathsf {club}$ denote the collection of club subsets of $\kappa $. Then the countable length everywhere club uniformization holds for $\kappa $: For every relation $R \subseteq {}^{<{\omega _1}}\kappa \times \mathsf {club}$ with the property that for all $\ell \in {}^{<{\omega _1}}\kappa $ and clubs $C \subseteq D \subseteq \kappa $, $R(\ell ,D)$ implies $R(\ell ,C)$, there is a uniformization function $\Lambda : \mathrm {dom}(R) \rightarrow \mathsf {club}$ with the property that for all $\ell \in \mathrm {dom}(R)$, $R(\ell ,\Lambda (\ell ))$. In particular, under these assumptions, for all $n \in \omega $, $\boldsymbol {\delta }^1_{2n + 1}$ satisfies the countable length everywhere club uniformization.
Rates of suicide in older adults may be higher than reported due to poor understandings of presentation of suicide ideation in this group. The objectives of this paper were to (i) review current measurement tools designed for older adults to detect suicide ideation and (ii) assess their psychometric properties.
Design:
We used a systematic review approach to identify measurement tools developed specifically for older adults without cognitive decline or impairment.
Results:
Ten articles that reported on a total of seven different measurement tools were identified. These included tools that focused on resiliency to suicide and those that measured risk of suicide behavior. There was wide variation across the articles: some were adaptations of existing scales to suit older populations, others were developed by authors; they varied in length from four to 69 items; a range of settings was used, and there was a mix of self-report and clinician-administered measures. Most displayed good psychometric properties, with both approaches showing similar quality. Limitations in terms of samples, settings, and measurement design are discussed.
Conclusion:
The case for specific measures for older adults is clear from this review. There appear to be unique factors that should be considered in understanding suicide ideation and behavior among older adults that may not be directly assessed in non-specific measurements. However, there is a need to expand the diversity of individuals included in measurement development to ensure they are appropriate across gender, culture and minority status, and for the views of professionals to be considered.
The Childbirth Expectations Questionnaire (CEQ; Gupton, A., Beaton, J., Sloan, J. & Bramadat, I.; 1991) evaluates the women childbirth expectation’s with 34 items organized in four dimensions: Pain and coping; Significant others; Nursing support and Interventions.
Objectives
To analyze the psychometric properties (construct validity using Confirmatory Factor Analysis, discriminant validity and reliability) of the Brazilian preliminary version of CEQ.
Methods
350 women (Mean age: 30.01±5.452) in the second trimester of pregnancy (Mean weeks of gestation=25.17±6.55), with uncomplicated pregnancies, completed the CEQ. To analyze discriminant validity, thirty of these women participated in a workshop (12 hours, integrated in the GentleBirth, a specific perinatal education intervention program) and fill in the CEQ again after approximately 8 weeks.
Results
After deleting seven items (1-3-20-24-33-34-35) and some errors were correlated the four-dimensional second-order model of CEQ presented good fit (χ2=2.496; RMSEA=.071; CFI=.845, TLI=.828). The CEQ Cronbach’s alpha for the total was α=.90; all factors presented good reliability: Pain coping (α=.87); Significant others (α=.66), Nursing support (α=.84), and Interventions (α=.76). The CEQ mean scores (total, Pain coping and Nursing support) were significantly higher after the workshop, indicating more positive expectations for childbirth (p<.05).
Conclusions
This additional validation study emphasizes that CEQ is an adequate measure of expectations of labour. It will be very useful to understand the correlates of childbirth expectations and also to access the efficacy of childbirth preparation programs.
Relations between states are usually framed in human terms, from partners to rivals, enemies or allies, polities and persons appear to engage in cognate relationships. Yet whether or not official ties and relationships among people from those states actually correspond remains less clear. “Friendship,” a term first applied to states in eighteenth-century Europe and mobilized in the (post)socialist world since the 1930s, articulates with particular clarity both the promise and the limitations of harmonized personal and state ties. Understandings of friendship vary interculturally, and invocations of state-state friendship may be accompanied by a distinct lack of amity among populations. Such is the case between China and Russia today, and this situation therefore raises wider questions over how we should understand interstate and interpersonal relationships together. Existing social scientific work has generally failed to locate either the everyday in the international or the international in the everyday. Focusing on both Chinese and Russian approaches to daily interactions in a border town and the official Sino-Russian Friendship, I thus suggest a new scalar approach. Applying this to the Sino-Russian case in turn reveals how specific contours of “difference” form a pivot around which relationships at both scales operate. This study thus offers both comparison between Chinese and Russian friendships, and a lens for wider comparative work in a global era of shifting geopolitics and cross-border encounters.
To examine the psychometric properties of the Chinese version of the Relevant Outcome Scale for Alzheimer’s disease (CROSA) among persons with AD (PWAD) and their caregivers in China.
Design:
A single-arm, open-label, multi-center study.
Setting:
Two tertiary general hospitals in Shanghai.
Participants:
A total of 336 PWAD and their family caregivers.
Intervention:
The PWAD completed a 12-week treatment with memantine after a baseline assessment.
Measurements:
The CROSA and the Chinese versions of the Mini-Mental State Examination, the Alzheimer’s Disease Assessment Scale-Cognitive Subscale, the Disability Activity of Dementia, the Neuropsychiatric Inventory Questionnaire, the Zarit Caregiver Burden Interview and the Self-Efficacy Questionnaire for Chinese Family Caregivers.
Results:
The Cronbach’s alpha for the total scale was 0.900, and the intraclass correlation coefficient and Pearson’s correlation coefficient were 0.910 (P < 0.001) and 0.836 (P < 0.001), respectively. Confirmatory factor analysis revealed the two-factor model to be consistent with the original version. For the known-group validity, the total score of the CROSA classified the PWAD into three stages and three MMSE score groups. Moderate to large correlations with the validated scales confirmed the criteria validity of the CROSA, and the convergent validity was confirmed via testing a hypothesized caregiving model; however, only minimal responsiveness was found among the deterioration group after 12 weeks of treatment with memantine.
Conclusions:
The reliability and validity of the CROSA was good or acceptable for use in daily clinical settings. Further studies are needed to examine the psychometric properties of the scale.
This introductory chapter discusses what a river is; why rivers are important, both as natural features that shape the Earth’s surface and as resources for society; the science of fluvial geomorphology, including a brief history of this field; the process-oriented perspective of the book; rivers as dynamic natural systems; general concepts, such as dynamic equilibrium, thresholds, and nonlinear system dynamics, that have been employed to describe the dynamics of river systems; and the importance of both physical processes and environmental/historical contingency as factors influencing the dynamics of river systems. It presents a conceptual model defining rivers as dynamic systems characterized by interaction among flow, sediment transport, and channel form. It defines a hierarchy of spatial and temporal scales relevant to the characterization of river systems.
A literature review identified nearly 500 papers in which references to quality of life (QoL) were made in the context of schizophrenia. Despite this, only two studies could be found where efforts had been made to assess the impact of pharmaceutical products on the QoL of patients with schizophrenia. It is argued that lack of progress in this area of research results from the absence of an adequate schizophrenia-specific QoL instrument. The present paper details the requirements for such an instrument, reviews health status instruments that have been used with schizophrenic patients and describes the methodology required for producing a new instrument. It is argued that the pharmaceutical industry should consider joint financing of such development work, given the importance of a reliable, valid and responsive outcome instrument for clinical trials. Such an instrument would also prove valuable when assessing alternative management programmes.
To perform a psychometric analysis of the Brazilian version of the Brief Social Phobia Scale (BSPS).
Materials and methods
Hundred and seventy-eight university students of both genders aged on average 21.2 years and identified as Social Anxiety Disorder (SAD) cases and non-cases was studied, with the structured clinical interview for DSM-IV being used as a parameter. The different instruments were applied in an individual manner in the presence of a rater and of an observer.
Results
The BSPS showed adequate internal consistency (0.48–0.88) and concurrent and divergent validity with the Beck Anxiety Inventory (BAI) (0.21–0.62), Social Phobia Inventory (0.24–0.82) and Self Statements During Public Speaking Scale (SSPS) (0.23–0.31). Discriminative validity revealed a sensitivity of 0.88–0.90 and a specificity of 0.81(0.83 for cut-off notes of 18/19. Factorial analysis demonstrated the presence of six factors that jointly explained 71.79% of data variance. Construct validity indicated some limits of the scale regarding the diagnosis of SAD. Inter-rater reliability was strong (0.86–1.00, p < 0.001).
Conclusions
The BSPS is adequate for use with university students, although further studies in different cultures, samples and contexts are still necessary.
The aim of this study was to test whether a positive and a negative component could be found in broadly defined schizophrenic patients. Therefore, 70 patients either in an exacerbated or in a stabilized phase were selected according to the criteria of at least 1 of the 4 following diagnostic systems: DSM III-R, Schneider, Carpenter, Langfeldt; principal component analyses (PCA) were carried out with the 9 global ratings of the Scales for Assessment of Negative and Positive Symptoms (SANS and SAPS) and with the Positive and Negative Syndrome Scale (PANSS). The PCA of the SANS-SAPS global ratings yielded a 3-factor solution explaining 72.14% of the total variance, depicting a negative, a positive and a disorganization component. The PCA of the PANSS provided a 5-factor solution with a total explained variance of 55.98%. The first 3 factors were similar to those of the SANS-SAPS global rating analysis. The results showed that the positive and negative components described in a homogeneous schizophrenic population could be replicated in a larger and more heterogeneous group of schizophrenic patients. The question regarding the sufficiency of the positive-negative dichotomy was strengthened by the presence of a third disorganization component which explained as much of the variance as the positive component.
This study is a careful examination of the relationships between different components of the alexithymia construct and state versus trait anxiety. In order to study the relations between anxiety and alexithymia in a subclinical population, we administered to 125 female college students a test battery including measures of alexithymia (TAS26), state and trait anxiety (STAI) and depression (QD2A). Results indicated positive correlations between depression, anxiety (state and trait) and alexithymia scores. Partial correlations revealed a tight link between trait anxiety and alexithymia. Furthermore, in agreement with the view that alexithymia is a multidimensional construct, the various alexithymia dimensions were found to be diversely correlated with anxiety. On the basis of partial correlation analyses, a descriptive model of the relationships between depression, state anxiety, trait anxiety and alexithymia was postulated. This model was confirmed by pathways analyses.
Assessing the effect of novel pharmaceutical treatments on the quality of life (QoL) of a patient, or group of patients, has been approached in numerous ways over the last 20 years. Techniques as diverse as single questions to multidimensional scales requiring trained assessors to devote several hours to each assessment; from generic questions about how life might have changed to specific issues such as the ability to use a toothbrush. In the pharmaceutical industry, the emphasis is on the registration of a product with national licensing bodies. Each body has tended to see the issue from a different perspective, which has driven study designs to be different in different countries; even different over time within one country. This paper emphasises the basic statistical steps necessary to ensure that a measure of QoL is appropriately recorded, while retaining sufficient flexibility to support the registration in several countries. Aspects about possible study design are included to assist with developing some simple concepts about analysing and then interpreting the results. It is not the intention of the paper to provide the answer, merely to provide the tools to develop the answer robustly. Put briefly, with the right approach generic solutions are feasible and these solutions will have greater utility. The challenge is to recognise exactly what QoL is, and not to deviate from it.
Taking up the definition of a model posited in Chapter 1, models can follow different purposes. This chapter introduces nine general purposes: theory development, generalisation, theory testing, understanding (of systems and their dynamics), explanation (of observed phenomena), prediction (of the system dynamics), decision support (for the derivation of ‘good’ policies and strategies), communication (of knowledge and information) and education (of students and young researchers); and two more technical purposes: integration of knowledge and mediation between scales. These eleven purposes are demonstrated using modelling studies from the literature in the disciplines of physics, ecology and economics. Further, a model may be general or specific, and it may be used for positive analysis (‘what is’) or normative analysis (‘what should be’), or a mixture of both.
The growing influence of transnational process, institutions and policy communities has contributed to the emergence of a global public policy that is distinct (although not separate) from the national process of policy-making. In this context gender equality and gender mainstreaming have become dominant policy and political narratives for addressing gender injustice. The focus of this paper is on developing the conceptual and theoretical links between global policy paradigms and gender equality and incorporating multi-scalarity, translation and disjuncture into our understanding of the ways in which policies are made, processed and enacted. The discussion begins by extending Hall's concept of policy paradigm as a nationally bounded entity and highlighting the transnational processes and institutions contributing to the emergence of a global policy paradigm and global policy space. It then goes on to highlight the fluidity of policy paradigms and the importance of moving beyond the focus on techno-managerial “order” as the essence of the policy paradigm and indicators of change and instead to bring into sharper focus disjuncture and tensions.
