AbstractLevering change is hard, and an incremental process. In the education process it requires an interaction between teachers, resources and learners. Levering change with human resources—teachers themselves, is a long term, time-intensive process requiring investment and commitment. The teacher–resources relationship is complex and not always optimal, particularly in disadvantaged educational environments where resources are constrained, and the education system is centralized and highly regulated. This article posits a mathematics teaching framework developed in a low-income educational context to make more transparent the relationship between teachers and resources to the benefit of learning both of teachers and of learners.

The cornerstone of cognitive treatment (CT) for OCD is based upon the knowledge that unwanted intrusions are essentially a universal experience. As such, it is not the presence of the intrusion that is problematic but rather the associated meaning or interpretation. Treatment is flexible, depending upon the nature of the appraisals and beliefs, but can include strategies focused on inflated responsibility and overestimation of threat, importance and control of thoughts, and the need for perfectionism and certainty. The role of concealment and the relationship to personal values are important maintaining and etiological factors. The short-term and long-term treatment outcome is reviewed, along with predictors of treatment response and mechanisms of action, and the chapter concludes with future directions regarding CT for OCD.

The Relationship

Organizational ambidexterity is widely recognized as necessary for the economic sustainability of firms operating in the financial sector. While the management literature has recognized several forms of ambidexterity, the relationship between them and their relative merits remain unclear. By studying a process of implementation of ambidextrous capabilities within a large Scandinavian financial firm, we explore the role of top-down reforms and bottom-up reactions in determining the development of sector-specific innovative capabilities. We find that blended ambidexterity follows naturally from the attempt to correct the tensions arising from harmonic ambidextrous blueprints. The resulting blended practice appears to be closely related to the reciprocal model of ambidexterity, which appears to be a necessity rather than a choice, for large firms attempting to develop innovative capabilities. Consequently, we suggest to re-interpret current taxonomies of ambidexterity not as alternative blueprints, but rather as stages in a long-term process of transition.

AbstractUnderstanding the dynamics and distribution of CO2 in the subsurface atmosphere of carbonate karst massifs provides important insights into dissolution and precipitation processes, the role of karst systems in the global carbon cycle, and the use of speleothems for paleoclimate reconstructions. We discuss long-term microclimatic observations in a passage of Postojna Cave, Slovenia, focusing on high spatial and temporal variations of pCO2. We show (1) that the airflow through the massif is determined by the combined action of the chimney effect and external winds and (2) that the relationship between the direction of the airflow, the geometry of the airflow pathways, and the position of the observation point explains the observed variations of pCO2. Namely, in the terminal chamber of the passage, the pCO2 is low and uniform during updraft, when outside air flows to the site through a system of large open galleries. When the airflow reverses direction to downdraft, the chamber is fed by inlets with diverse flow rates and pCO2, which enter via small conduits and fractures embedded in a CO2-rich vadose zone. If the spatial distribution of inlets and outlets produces minimal mixing between low and high pCO2 inflows, high and persistent gradients in pCO2 are formed. Such is the case in the chamber, where vertical gradients of up to 1000 ppm/m are observed during downdraft. The results presented in this work provide new insights into the dynamics and composition of the subsurface atmosphere and demonstrate the importance of long-term and spatially distributed observations.

Bronchiolitis is the most common cause of hospitalization in infancy and is associated with a higher risk for the development of childhood asthma. However, not all children hospitalized with bronchiolitis will develop asthma. The mechanisms underlying asthma development following bronchiolitis hospitalization are complex. Immune responses to respiratory viruses may underlie both bronchiolitis severity and long-term sequela (such as asthma). Interferons (IFNs) are important components of innate immune responses to respiratory viruses and could influence both asthma development and asthma exacerbations. However, the nature of the relationship between interferon production and wheezing illnesses is controversial. For example, low peripheral blood IFN responses at birth have been linked with recurrent wheeze and asthma development. In contrast, there is evidence that severe illnesses (e.g., hospitalization for bronchiolitis) are associated with increased IFN responses during acute infection (bronchiolitis hospitalization) and a higher risk for subsequent asthma diagnosis. Furthermore, mechanistic studies suggest that bronchial epithelial cells from asthmatic children have impaired IFN responses to respiratory viruses, which may enable increased viral replication followed by exaggerated secondary IFN responses. This review aims to discuss controversies around the role of IFNs as drivers of susceptibility to asthma development following bronchiolitis hospitalization. Past evidence from both mechanistic and cohort studies are discussed. We will highlight knowledge gaps that can inform future research study design.

Obesity is caused by a combination of hereditary and environmental factors. Despite extensive study, contemporary through diet, exercise, education, surgery, and pharmacological treatments, no effective long-term solution has been found to this epidemic. Over the last decade, there has been a tremendous advancement in understanding the science of epigenetics, as well as a rise in public interest in learning more about the influence of diet and lifestyle choices on the health of an individual. Without affecting the underlying DNA sequence, epigenetic alterations impact gene expression. Previous animal studies have shown a link between the type of diet and expression or suppression of obesity genes, but there are very few human studies that demonstrate the relationship between dietary intake and obesity gene expression. This review highlights the effects of carbohydrates, lipids, and protein intake from the diet on obesity-related genes.

Environmental health effects during urbanization have attracted much attention. However, knowledge is lacking on the relationship between long-term cumulative residential environment and health effects on individuals during rapid transformations in urban physical and social space. Taking Guangzhou, China, as a case example, this study analyzed the relationship between long-term exposure to green environments and residents’ mental health under urban spatial restructuring. Based on a household survey in 2016, 820 residents who have lived in Guangzhou for more than 15 years were used as the sample. High-resolution remote sensing images were used to assess the long-term green exposure of residents. The results indicate that long-term green exposure in residential areas had a negative correlation with residents’ mental health (p < 0.05), and the correlation was strongest for the cumulative green environment in the last five years. However, this significant effect was moderated by income and residential location. Green exposure had a positive relationship with mental health for low income groups, and a negative relationship for middle and high income groups. In addition, residents living farther away from the city center were likely to have fewer green environmental health benefits. Residential relocation in a rapidly urbanizing and transforming China has led to the continuous differentiation of residential green environments among different income groups, which has also caused different mental health effects from green exposure. It provides empirical evidence and theoretical support for policymakers to improve the urban environment and reduce environmental health disparities by considering social differences and residential location.

In early 2018, the Polish parliament adopted controversial legislation criminalising assertions regarding the complicity of the ‘Polish Nation’ and the ‘Polish State’ in the Holocaust. The so-called Polish Holocaust Law provoked not only a heated debate in Poland, but also serious international tensions. As a result, it was amended only five months after its adoption. The reason why it is worth taking a closer look at the socio-cultural foundations and political functions of the short-lived legislation is twofold. Empirically, the short history of the Law reveals a great deal about the long-term role of Jews in the Polish collective memory as an unmatched Significant Other. Conceptually, the short life of the Law, along with its afterlife, helps capture poll-driven, manifestly moralistic and anti-pluralist imaginings of the past, which I refer to as ‘mnemonic populism’. By exploring the relationship between popular and political images of the past in contemporary Poland, this article argues for joining memory and populism studies in order to better understand what can happen to history in illiberal surroundings.

Traditional Human Resource Management (HRM) focusing on maintaining the status quo is no longer in the spotlight. Sustainable HRM has become the new approach, emphasizing the need to attend to organizational results directed toward reaching different goals and integrating the needs of diverse stakeholders. Moreover, in response to the challenges that organizations face in volatile, uncertain, complex, and ambiguous (VUCA) environments, Human Resource (HR) practices can contribute to the development of idiosyncratic deals (negotiation of individual HR practices) that might facilitate employees’ creativity and eudaimonic well-being in the long term and, thus, the sustainability of these organizations. Thus, the aim of this study is to test the mediating role of idiosyncratic deals (i-deals) in the unfolding relationship between HR practices, eudaimonic well-being and creative performance. Using a longitudinal database (three waves), the hypotheses are tested using structural equations modeling. The results support the idea that HR practices function as an antecedent for i-deals. More specifically, i-deals fully mediate the relationship between HR practices and eudaimonic well-being. In turn, i-deals and eudaimonic well-being fully mediate the relationship between HR practices and creative performance, which suggests that, through i-deals, HR practices become more beneficial for both employees and employers. In conclusion, these results are important for sustainable HR development, because HR practices enhance i-deals, which increase well-being, enhancing performance in the long term.

Abstract A significant educational development that has occurred in Australia in recent years has been the emergence of the genre-based approach to the teaching of writing. The theoretical basis of this approach lies in the systemic, functional model of language developd by M.A.K. Halliday and others. Thus it is an approach to writing which focuses on the relationship between written texts and the contexts in which written texts are produced. This paper traces the development of the genrebased approach. It discusses the meaning of the term “genre”, and describes the contribution of people such as Kress, Martin, Rothery and Christie to the theoretical development of the approach. It also describes some of the educational programs that have been developed to implement the genrebased approach. It is argued in this paper that the most significant contribution of the genre-based approach to writing is the development of an explicit understanding of the role of language in the educational context and a linguistic description of the major genres that children are expected to learn as they learn to write. It is in this area, that is, making the role of language explicit, that the genre-based approach differs most from other approaches such as the “growth model” of English teaching and “process writing” which have been influential in recent years.

Abstract Tracing the extended Kujujī family unit, originally from Western Azerbaijan, through the fourteenth up to the seventeenth century, I am especially interested in the interplay between members of the Kujujī family, their professional background, and the poetry they composed. Poetry is interpreted as a mode of transmission, understanding panegyric and mystical forms of poetry as a means to shape and reinforce family identities in reciprocal relationships – in our case the relationship between the local Sufi-notable family network of the Kujujīs with the respective ruling families of the Jalayirids and Safavids. The article explores their poetry, the poets as actors of transmission and the links that are created between distant members of the “imagined” family of the Kujujīs as expressed in literary anthologies (taẕkiras). Moving beyond traditional perceptions of one-on-one, client-patron relations in the production of court poetry and emphasizing the role of families creates a long-term perspective and re-evaluates classical Persian poetry as intra-generational cultural bond.
