A review of research and practice for the industrial networks of the future

Academic researchers have followed closely the interest of companies in establishing industrial networks by studying aspects such as social interaction and contractual relationships. But what patterns underlie the emergence of industrial networks and what support should research provide for practitioners? First, it appears that manufacturing is becoming a commodity rather than a unique capability, which accounts especially for low-technology approaches in downstream parts of the network, for example, in assembly operations. Second, the increased tendency towards specialisation has forced other, upstream, parts of industrial networks to introduce advanced manufacturing technologies for niche markets. Third, the capital market for investments in capacity, and the trade in manufacturing as a commodity, dominates resource allocation to a larger extent than was previously the case. Fourth, there is becoming a continuous move towards more loosely connected entities that comprise manufacturing networks. Finally, in these networks, concepts for supply chain management should address collaboration and information technology that supports decentralised decision-making, in particular to address sustainable and green supply chains. More traditional concepts, such as the keiretsu and chaibol networks of some Asian economies, do not sufficiently support the demands now being placed on networks. Research should address these five fundamental challenges to prepare for the industrial networks of 2020 and beyond. © 2010 Springer-Verlag London.

A new dynamic framework for managing ERP development and enterprise strategy

The enterprise management (EM) approach provides a holistic view of organizations and their related information systems. In order to align information technology (IT) innovation with global markets and volatile virtualization, traditional firms are seeking to reconstruct their enterprise structures alongside repositioning strategy and establish new information system (IS) architectures to transform from single autonomous entities into more open enterprises supported by new Enterprise Resource Planning (ERP) systems. This chapter shows how ERP engage-abilities cater to three distinctive EM patterns and resultant strategies. The purpose is to examine the presumptions and importance of combing ERP and inter-firm relations relying on the virtual value chain concept. From a review of the literature on ERP development and enterprise strategy, exploratory inductive research studies in Zoomlion and Lanye have been conducted. In addition, the authors propose a dynamic conceptual framework to demonstrate the adoption and governance of ERP in the three enterprise management forms and points to a new architectural type (ERPIII) for operating in the virtual enterprise paradigm. © 2012, IGI Global.

Community relation discovery by named entities

Discovering who works with whom, on which projects and with which customers is a key task in knowledge management. Although most organizations keep models of organizational structures, these models do not necessarily accurately reflect the reality on the ground. In this paper we present a text mining method called CORDER which first recognizes named entities (NEs) of various types from Web pages, and then discovers relations from a target NE to other NEs which co-occur with it. We evaluated the method on our departmental Website. We used the CORDER method to first find related NEs of four types (organizations, people, projects, and research areas) from Web pages on the Website and then rank them according to their co-occurrence with each of the people in our department. 20 representative people were selected and each of them was presented with ranked lists of each type of NE. Each person specified whether these NEs were related to him/her and changed or confirmed their rankings. Our results indicate that the method can find the NEs with which these people are closely related and provide accurate rankings.

LRD : Latent Relation Discovery for vector space expansion and information retrieval

In this paper, we propose a text mining method called LRD (latent relation discovery), which extends the traditional vector space model of document representation in order to improve information retrieval (IR) on documents and document clustering. Our LRD method extracts terms and entities, such as person, organization, or project names, and discovers relationships between them by taking into account their co-occurrence in textual corpora. Given a target entity, LRD discovers other entities closely related to the target effectively and efficiently. With respect to such relatedness, a measure of relation strength between entities is defined. LRD uses relation strength to enhance the vector space model, and uses the enhanced vector space model for query based IR on documents and clustering documents in order to discover complex relationships among terms and entities. Our experiments on a standard dataset for query based IR shows that our LRD method performed significantly better than traditional vector space model and other five standard statistical methods for vector expansion.

Industrial networks of the future:a critical commentary on research and practice

Academia has followed the interest by companies in establishing industrial networks by studying aspects such as social interaction and contractual relationships. But what patterns underlie the emergence of industrial networks and what support should research provide for practitioners? Firstly, it seems that manufacturing is becoming a commodity rather than a unique capability, which accounts especially for low-technology approaches in downstream parts of the network, for example in assembly operations. Secondly, the increased tendency to specialize forces other parts of industrial networks to introduce advanced manufacturing technologies for niche markets. Thirdly, the capital market for investments in capacity and the trade in manufacturing as a commodity dominates resource allocation to a larger extent. Fourthly, there will be a continuous move toward more loosely connected entities forming manufacturing networks. More traditional concepts, like keiretsu and chaibol networks, do not sufficiently support this transition. Research should address these fundamental challenges to prepare for the industrial networks of 2020 and beyond.

Metaphors in spoken academic discourse in german and english

Metaphors have been increasingly associated with cognitive functions, which means that metaphors structure how we think and express ourselves. Metaphors are embodied in our basic physical experience, which is one reason why certain abstract concepts are expressed in more concrete terms, such as visible entities, journeys, and other types of movement, spaces etc. This communicative relevance also applies to specialised, institutionalised settings and genres, such as those produced in or related to higher education institutions, among which is spoken academic discourse. A significant research gap has been identified regarding spoken academic discourse and metaphors therein, but also given the fact that with increasing numbers of students in higher education and international research and cooperation e.g. in the form of invited lectures, spoken academic discourse can be seen as nearly omnipresent. In this context, research talks are a key research genre. A mixed methods study has been conducted, which investigates metaphors in a corpus of eight fully transcribed German and English L1 speaker conference talks and invited lectures, totalling to 440 minutes. A wide range of categories and functions were identified in the corpus. Abstract research concepts, such as results or theories are expressed in terms of concrete visual entities that can be seen or shown, but also in terms of journeys or other forms of movement. The functions of these metaphors are simplification, rhetorical emphasis, theory-construction, or pedagogic illustration. For both the speaker and the audience or discussants, anthropomorphism causes abstract and complex ideas to become concretely imaginable and at the same time more interesting because the contents of the talk appear to be livelier and hence closer to their own experience, which ensures the audience’s attention. These metaphor categories are present in both the English and the German sub corpus of this study with similar functions.

Theorizing accounting and other [calculative] practices in private equity:Experimenting with Schatzki’s ‘site’ ontology

This thesis contributes to social studies of finance and accounting (Vollmer, Mennicken, & Preda, 2009) and the practice theory literatures (Feldman & Orlikowski, 2011) by experimenting (Baxter & Chua, 2008) with concepts developed by Theodore Schatzki and demonstrating their relevance and usefulness in theorizing and explaining accounting and other organizational phenomena. Influenced by Schatzki, I have undertaken a sociological investigation of the practices, arrangements, and nexuses forming (part of) the social ‘site’ of private equity (PE). I have examined and explained the organization of practices within the PE industry. More specifically, I have sought to throw light on the practice organizations animating various PE practices. I have problematized a particular aspect of Schatzki’s practice organization framework: ‘general understanding’, which has so far been poorly understood and taken for granted in the accounting literature. I have tried to further explore the concept to clarify important definitional issues surrounding its empirical application. In investigating the forms of accounting and control practices in PE firms and how they link with other practices forming part of the ‘site’, I have sought to explain how the ‘situated functionality’ of accounting is ‘prefigured’ by its ‘dispersed’ nature. In doing so, this thesis addresses the recent calls for research on accounting and control practices within financial services firms. This thesis contributes to the social studies of finance and accounting literature also by opening the blackbox of investment [e]valuation practices prevalent in the PE industry. I theorize the due diligence of PE funds as a complex of linked calculative practices and bring to fore the important aspects of ‘practical intelligibility’ of the investment professionals undertaking investment evaluation. I also identify and differentiate the ‘causal’ and ‘prefigurational’ relations between investment evaluation practices and the material entities ‘constituting’ those practices. Moreover, I demonstrate the role of practice memory in those practices. Finally, the thesis also contributes to the practice theory literature by identifying and attempting to clarify and/or improve the poorly defined and/or underdeveloped concepts of Schatzki’s ‘site’ ontology framework.

Formative variables and unreal variables:why the formative MIMIC model is invalid

In this rejoinder, we provide a response to the three commentaries written by Diamantopoulos, Howell, and Rigdon (all this issue) on our paper The MIMIC Model and Formative Variables: Problems and Solutions (also this issue). We contrast the approach taken in the latter paper (where we focus on clarifying the assumptions required to reject the formative MIMIC model) by spending time discussing what assumptions would be necessary to accept the use of the formative MIMIC model as a viable approach. Importantly, we clarify the implications of entity realism and show how it is entirely logical that some theoretical constructs can be considered to have real existence independent of their indicators, and some cannot. We show how the formative model only logically holds when considering these ‘unreal’ entities. In doing so, we provide important counter-arguments for much of the criticisms made in Diamantopoulos’ commentary, and the distinction also helps clarify a number of issues in the commentaries of Howell and Rigdon (both of which in general agree with our original paper). We draw together these various threads to provide a set of conceptual tools researchers can use when thinking about the entities in their theoretical models.

The challenges faced by reporting entities on their transition to international financial reporting standards:a qualitative study

This study explores the challenges of implementing International Financial Reporting Standards (IFRS) at the organisational level. Based on interviews with experts with aggregated experience relating to the transition projects of over 170 reporting entities, this paper highlights the main challenges in delivering a successful implementation of IFRS. The findings show that the problems faced in implementation include lack of education and training, securing executive-level support, identifying and responding to the wider business-related implications of the transition, and issues with capturing the necessary information for reporting under IFRS.This paper complements the existing literature and offers a qualitative alternative to considering the transition to IFRS, offering insight into the organisational context of IFRS implementation. These insights are useful not only from a historic perspective, but also for organisations and regulators in the many jurisdictions where IFRS is permitted but not required, where more reporting entities will voluntarily move to IFRS-based reporting in the future. More broadly, they are also applicable to the challenges faced in implementing new and significantly revised IFRSs.

Language policy and governmentality in businesses in Wales:a continuum of empowerment and regulation

In this paper, I examine how language policy acts as a means of both empowering the Welsh language and theminority language worker and as a means of exerting power over them. For this purpose, the study focuses on a particular site: private sector businesses in Wales. Therein, I trace two major discursive processes: first, the Welsh Government’s national language policy documents that promote corporate bilingualism and bilingual employees as value-added resources; second, the practice and discourse of company managers who sustain or appropriate such promotional discourses for creating and promoting their own organisational values. By drawing on concepts from governmentality, critical language policy and discourse studies, I show that promoting bilingualism in business is characterised by local and global governmentalities. These not only bring about critical shifts in valuing language as symbolic entities attached to ethnonational concerns or as promotional objects that bring material gain. Language governmentalities also appear to shape new forms of ‘languaging’ the minority language worker as selfgoverning, and yet, governed subjects who are ultimately made responsible for ‘owning’ Welsh.

Residue-specific investigation of the relationship between oxidation and activity of a dual specificity phosphatase by mass spectrometry

Redox regulation of signalling pathways is critical in proliferation and apoptosis; redox imbalance can lead to pathologies such as inflammation and cancer. Vaccinia H1-related protein (VHR; DUSP3) is a dual-specificity phosphatase important in controlling MAP kinase activity during cell cycle. the active-site motif contains a cysteine that acts as a nucleophile during catalysis. We used VHR to investigate the effect of oxidation in vitro on phosphatase activity, with the aim of determining how the profile of site-specific modification related to catalytic activity. Recombinant human VHR was expressed in E. coli and purified using a GST-tag. Protein was subjected to oxidation with various concentrations of SIN-1 or tetranitromethane (TNM) as nitrating agents, or HOCl. the activity was assayed using either 3-O-methylfluorescein phosphate with fluorescence detection or PIP3 by phosphate release with malachite green. the sites of oxidation were mapped using HPLC coupled to tandem mass spectrometry on an ABSciex 5600TripleTOF following in-gel digestion. More than 25 different concentration-dependent oxidative modifications to the protein were detected, including oxidations of methionine, cysteine, histidine, lysine, proline and tyrosine, and the % oxidized peptide (versus unmodified peptide) was determined from the extracted ion chromatograms. Unsurprisingly, methionine residues were very susceptible to oxidation, but there was a significant different in the extent of their oxidation. Similarly, tyrosine residues varied greatly in their modifications: Y85 and Y138 were readily nitrated, whereas Y38, Y78 and Y101 showed little modification. Y138 must be phosphorylated for MAPK phosphatase activity, so this susceptibility impacts on signalling pathways. Di- and tri- oxidations of cysteine residues were observed, but did not correlate directly with loss of activity. Overall, the catalytic activity did not correlate with redox state of any individual residue, but the total oxidative load correlated with treatment concentration and activity. This study provides the first comprehensive analysis of oxidation modifications of VHR, and demonstrates both heterogenous oxidant effects and differential residue susceptibility in a signalling phosphatase.

Reversible oxidation of phosphatase and tensin homolog (PTEN) alters its interactions with signaling and regulatory proteins

Phosphatase and tensin homolog (PTEN) is involved in a number of different cellular processes including metabolism, apoptosis, cell proliferation and survival. It is a redox-sensitive dual-specificity protein phosphatase that acts as a tumor suppressor by negatively regulating the PI3K/Akt pathway. While direct evidence of redox regulation of PTEN downstream signaling has been reported, the effect of PTEN redox status on its protein-protein interactions is poorly understood. PTEN-GST in its reduced and a DTT-reversible H2O2-oxidized form was immobilized on a glutathione-sepharose support and incubated with cell lysate to capture interacting proteins. Captured proteins were analyzed by LC-MSMS and comparatively quantified using label-free methods. 97 Potential protein interactors were identified, including a significant number that are novel. The abundance of fourteen interactors was found to vary significantly with the redox status of PTEN. Altered binding to PTEN was confirmed by affinity pull-down and Western blotting for Prdx1, Trx, and Anxa2, while DDB1 was validated as a novel interactor with unaltered binding. These results suggest that the redox status of PTEN causes a functional variation in the PTEN interactome. The resin capture method developed had distinct advantages in that the redox status of PTEN could be directly controlled and measured.

Can neurodegenerative disease be defined by four 'primary determinants':anatomy, cells, molecules, and morphology?

Traditional methods of describing and classifying neurodegenerative disease are based on the clinico-pathological concept supported by molecular pathological studies and defined by 'consensus criteria'. Disease heterogeneity, overlap between disorders, and the presence of multiple co-pathologies, however, have questioned the validity and status of many traditional disorders. If cases of neurodegenerative disease are not easily classifiable into distinct entities, but more continuously distributed, then a new descriptive framework may be required. This review proposes that there are four key neuropathological features of neurodegenerative disease (the 'primary determinants') that could be used to provide such a framework, viz., the anatomical pathways affected by the disease ('anatomy'), the cell populations affected ('cells'), the molecular pathology of 'signature' pathological lesions ('molecules'), and the morphological types of neurodegeneration ('morphology'). This review first discusses the limitations of existing classificatory systems and second provides evidence that the four primary determinants could be used as axes to define all cases of neurodegenerative disease. To illustrate the methodology, the primary determinants were applied to the study of a group of closely related tauopathy cases and to heterogeneity within frontotemporal lobar degeneration with TDP-43 proteinopathy (FTLD-TDP).

Antidepressant/anxiolytic and anti-nociceptive effects of novel 2-substituted 1,4-benzodiazepine-2-ones

Oxazepam (4a) has been used as overall starting material in the synthesis of novel 2-substituted 1,4-benzodiazepines. By reacting Oxazepam 4a with commercially available hydrazines, hydrazides, semicarbazide, aminoguanidine and N,N-dimethylamino aniline in ethanol under acetic conditions, a series of diazenyl-1,4-benzodiazepines 5a-5i and 2-amino- 1,4-benzodiazepine 5k were obtained in good yields. These novel compounds served as new chemical entities (NCE) for testing in mice. The diazo-benzodiazepine 5d has shown a promising antidepressant effect in initial experiments in vivo at a dose of 5 mg/kg. The highly coloured 2-aminobenzodiazepine derivative 5k showed over a dose range from 5-50 mg/kg an analgesic effect in mice. © Singh et al.
