SCHIZORIZA controls an asymmetric cell division and restricts epidermal identity in the Arabidopsis root
The primary root of Arabidopsis has a simple cellular organisation. The fixed radial cell pattern results from stereotypical cell divisions that occur in the meristem. Here we describe the characterisation of schizoriza (scz), a mutant with defective radial patterning. In scz mutants, the subepidermal layer (ground tissue) develops root hairs. Root hairs normally only form on epidermal cells of wildtype plants. Moreover, extra periclinal divisions (new wall parallel to surface of the root) occur in the scz root resulting in the formation of supernumerary layers in the ground tissue. Both scarecrow (scr) and short root (shr) suppress the extra periclinal divisions characteristic of scz mutant roots. This results in the formation of a single layered ground tissue in the double mutants. Cells of this layer develop root hairs, indicating that mis-specification of the ground tissue in scz mutants is uncoupled to the cell division defect. This suggests that during the development of the ground tissue SCZ has two distinct roles: (1) it acts as a suppressor of epidermal fate in the ground tissue, and (2) it is required to repress periclinal divisions in the meristem. It may act in the same pathway as SCR and SHR
The limits of process: On (re)reading Henri Bergson
This article offers a reading of the work of Henri Bergson as it pertains to organizations through the lens of ideas drawn from critical realism. It suggests an alternative to interpretations based on a stark division between process and realist perspectives. Much of the existing literature presents a rather partial view of Bergsonâs work. A review suggests some interesting parallels with themes in critical realism, notably the emergence of mind. Critical realism has a focus on process at its heart, but is also concerned with how the products of such processes become stabilized and form the conditions for action. This suggests that attention might usefully be paid to the relationship between organizational action and the sedimented practices grouped under the heading of âroutinesâ. More attention to Bergsonâs account of the relationship between instinct, intuition and intelligence provides a link to the social character of thought, something which can be mapped on to Archerâs work on reflexivity and the âinternal conversationâ. This suggests that our analyses need to pay attention to both memory and history, to building and dwelling, rather than the one-sided focus found in some process theory accounts
Structure and play: rethinking regulation in the higher education sector
This paper explores possible tactics for academics working within a context of increasing regulation and constraint. One suggested tactic is to move outside of a creativity-conformity binary. Rather than understanding creativity and conformity as separable, where one is seen as excluding the other, the authors consider the potential of examining the relationships between them. The theme of 'structure and play' illustrates the argument. In the first part of the paper, using various examples from art and design - fields generally associated with creativity - the authors explore the interrelatedness of creativity and conformity. For example, how might design styles, which are generally understood as creative outcomes, constrain creativity and lead to conformity within the design field? Is fashion producing creativity or conformity? Conversely, the ways in which conformity provides the conditions for creativity are also examined. For example, the conformity imposed by the state on artists in the former communist bloc contributed to a thriving underground arts movement which challenged conformity and state regulation. Continuing the theme of 'structure and play', the authors recount a story from an Australian university which foregrounds the ongoing renegotiation of power relations in the academy. This account illustrates how programmatic government in a university, with its aim of regulating conduct, can contribute to unanticipated outcomes. The authors propose that a Foucauldian view of distributed power is useful for academics operating in a context of increasing regulation, as it brings into view sites where power might begin to be renegotiated
STS in management education: connecting theory and practice
This paper explores the value of science and technology studies (STS) to management education. The work draws on an ethnographic study of second year management undergraduates studying decision making. The nature and delivery of the decision making module is outlined and the value of STS is demonstrated in terms of both teaching method and module content. Three particular STS contributions are identified and described: the social construction of technological systems; actor network theory; and ontological politics. Affordances and sensibilities are identified for each contribution and a discussion is developed that illustrates how these versions of STS are put to use in management education. It is concluded that STS has a pivotal role to play in critical management (education) and in the process offers opportunities for new forms of managin
Existential Communication and Leadership
The aim of this article is to introduce and explain a number of important existentialist philosophers and concepts that we believe can contribute to a critical approach to leadership theory. Emphasis is placed on understanding the nature of communication from an existentialist perspective and so Jaspers' conceptualization of existential communication is introduced along with important related concepts that may be regarded as important facets of leader communication including Being-in-the-world, the Other, intersubjectivity, dialogue and indirect communication. Particular attention is paid to Buber's ideas on communication as relationship and dialogue. Throughout, reference is made to contemporary, and what is often regarded as orthodox, thinking regarding the centrality of communication to leadership practice as a means by which to highlight the salience of an existentialist analysis
The New âHidden Abodeâ: Reflections on Value and Labour in the New Economy
In a pivotal section of Capital, volume 1, Marx (1976: 279) notes that, in order to understand the capitalist production of value, we must descend into the âhidden abode of productionâ: the site of the labour process conducted within an employment relationship. In this paper we argue that by remaining wedded to an analysis of labour that is confined to the employment relationship, Labour Process Theory (LPT) has missed a fundamental shift in the location of value production in contemporary capitalism. We examine this shift through the work of Autonomist Marxists like Hardt and Negri, Lazaratto and Arvidsson, who offer theoretical leverage to prize open a new âhidden abodeâ outside employment, for example in the âproduction of organizationâ and in consumption. Although they can open up this new âhidden abodeâ, without LPT's fine-grained analysis of control/resistance, indeterminacy and structured antagonism, these theorists risk succumbing to empirically naive claims about the ânew economyâ. Through developing an expanded conception of a ânew hidden abodeâ of production, the paper demarcates an analytical space in which both LPT and Autonomist Marxism can expand and develop their understanding of labour and value production in today's economy. </jats:p

Managing talent across advanced and emerging economies: HR issues and challenges in a Sino-German strategic collaboration
The human resource (HR) practices involved in global talent management continue to advance and evolve. A majority of talent management commentary is from multinational corporation (MNC) perspectives. However, the less commented small-to-medium-sized enterprise (SME) also confronts challenges grounded in economic (i.e. resources, finance), organisational (i.e. size, scope and structure) and consequent behavioural rationales (i.e. mindsets and stances). This paper establishes and examines a number of propositions which consider how these factors impact on an advanced economy SMEâs talent management in emerging economy collaborations. An interpretive qualitative methodology is employed using interviews conducted within two cases â SME and an MNC comparator case. The SME case is used as the driving force of the paper and its theoretical focus and findings. The MNC is used to develop issues as a comparator case. The findings show SME economic and organisational drivers producing behavioural dynamics in relation to mimesis of planned actions yet informal serendipitous responses in reality; a predilection for the proximate and familiar; design configurations of short-term expatriate visits and inpatriates; cumulating in ongoing inpatriate acculturisation and re-acculturation oscillation. Consequently, the implication is that the SME needs a HR practices encompassing resignation to the situation, flexibility and resilience in order to survive and progress

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions© 2019 CIWEM Large wood (re)introduction can deliver multiple benefits in river restoration, but there is a dearth of the detailed and longer-term post-project monitoring and evaluation required for improving best practice. We present findings from an academic partnership approach to post-project evaluation, based on successive MSc research projects on restored large wood in the Loddon catchment, UK. Field and modelling data reveal: (i) key differences in large wood features between restored and natural reaches; (ii) increased hydraulic retention and changes to mesohabitats associated with large wood; (iii) differences in macroinvertebrate community composition around large wood but a lack of site-level effects; (iv) interactions between macrophytes and large wood that may be specific to restored reaches; (v) a need for further field and modelling studies to inform the accurate representation of large wood in hydraulic models. Some key challenges in partnership working are identified to aid planning and effectiveness of future collaborations

Symbolism in bank marketing and architecture: the headquarters of National Provincial Bank of England
This article undertakes an analysis of the symbolism present in the architecture and design in nineteenth century British banking. It focuses upon the headquarters of National Provincial Bank of England, which was built in the 1860s. It explores the symbols and messages that those at the bank wished to communicate to those that viewed the building. The analysis finds that those at the bank impressed its national identity, achieved through its extensive branch network, as its key message which differentiated it from its rivals. Other symbols emphasized that it had adapted to the local market and was equal in terms of competency and richness in comparison to its competitors. We argue that these messages became part of the organizationâs identity and its brand, as well as the culture of the City of London more broadly. The article provides a new explanation for symbolic meanings represented by bank architecture. It integrates the existing discussion of bank architecture in historical research with the theoretical frameworks and literature being developed in organizational identity and branding
