Identifying and improving deficient business processes to prepare SMEs for ERP implementation

The study reported in this paper aims to identify, explore and improve hitherto deficient business processes for SMEs in order to prepare them for ERP implementation projects. When business process improvement is traditionally perceived as a task that is particularly related to the ERP project phase, this paper argues that broad changes of business processes should actually be performed well before implementing the system. The research took a Cypriot SME as a case study, and adopted in-depth interview as the main method of data collection. The qualitative data collected was analysed by using an inductive thematic analysis approach. The findings identified that business deficiencies and problems, which can impact potential ERP adoption and usage in SMEs, can be localised across business processes, e.g. sales ordering and stock controlling processes. Disregarding these deficient business processes and business drawbacks in the ERP preparation stage will have implications not just for the subsequent ERP project, but also for the long-term ERP usage

Towards a combined Rotational-Differential Cryptanalytic Framework

In this report, we suggest a new cryptanalytic framework of constructing distinguishers which can be eventually extended to full attacks in the related-key scenario. We name this new paradigm as ”Relational Cryptanalysis”. The main idea is to exhibit the non-randomness of a given encryption algorithm by observing the propagation of specific sets of plaintexts of the form (P,P′) such that these pairs satisfy some rotational and differential properties of the form R1(P) = P′ and P ⊕ P′ ∈ ∆P, for some rotational symmetry R1 and fixed set of differences ∆P . Except of rotational and differential properties, we can add any other relation which seems to hold for a reduced number of rounds of the cryptographic primitive we study. Intuitively, we expect that by adding more relations we increase the observed probability of the propagation and this result to stronger statistical distinguishers

Towards ERP success in SMEs through business process review prior to implementation

Purpose – ERP systems are not the exclusive concern of large companies anymore. More and more small and medium sized enterprises (SMEs) are now engaging with the implementation and exploitation of this type of system. However, reports of ERP failure are numerous and frequent. Very often, this failure results from technical and implementation problems. But even more frequently, it is due to lack of preparation, by the companies themselves, for the implementation process. The purpose of the study reported in this paper was to identify and explore ways in which SMEs may need to prepare themselves before implementing ERP systems. Design/methodology/approach – The research took a Cypriot SME as a case study and adopted an inductive approach supported by in-depth interviews as the main method of data collection. The qualitative data collected were analysed by using a thematic analysis approach. Subsequently, a rich picture and concept maps were used to represent the findings generated. Findings – The study identified that business deficiencies and problems, which can impact potential ERP adoption and usage in SMEs, can be localised across business processes boundaries, such as sales order processing, stock control, and bill of materials management, etc. These business problems were found to be attributed to a variety of organisational, technical and human-related reasons. Therefore, this study established that in order to implement ERPs successfully, organisations may require changes in people's work practices and understanding of technology, ownership and control of business processes, as well as organisational wide policies. Research limitations/implications – This study contributes to the knowledge of ERP preparation and business process improvement in SMEs. Practical implications – The findings of the paper provide useful insights for both academic and practitioners who are thinking of implementing ERP systems. The paper contributes to the body of literature on issues that SMEs may need to reflect upon before embarking in a costly and resource intensive process of ERP implementation. Originality/value – Business process improvement is traditionally considered as the result of an ERP project phase. This is how the large majority of the academic literature and the totality of marketing information by ERP vendors portray it. In fact, the reality of practice shows a different scenario with frequent reports of failure and inadequate ERP implementation. This paper aims at breaking with this myth, by proposing that ERPs cannot resolve the large variety of deficient business processes and internal problems that may exist in SMEs. Therefore, this study argues that SMEs need to prepare in advance by engaging in business process reviews prior to the ERP implementation that is engaging in a pre-implementation or preparation phase

Lipopolysaccharide-primed heterotolerant dendritic cells suppress experimental autoimmune uveoretinitis by multiple mechanisms

Exposure of bone-marrow-derived dendritic cells (BMDC) to high-dose ultrapure lipopolysaccharide for 24 hr (LPS-primed BMDC) enhances their potency in preventing inter-photoreceptor retinoid binding protein: complete Freund's adjuvant-induced experimental autoimmune uveoretinitis (EAU). LPS-primed BMDC are refractory to further exposure to LPS (= endotoxin tolerance), evidenced here by decreased phosphorylation of TANK-binding kinase 1, interferon regulatory factor 3 (IRF3), c-Jun N-terminal kinase and p38 mitogen-activated protein kinase as well as impaired nuclear translocation of nuclear factor κB (NF-κB) and IRF3, resulting in reduced tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-12 and interferon-β secretion. LPS-primed BMDC also show reduced surface expression of Toll-like receptor-4 and up-regulation of CD14, followed by increased apoptosis, mediated via nuclear factor of activated T cells (NFATc)-2 signalling. LPS-primed BMDC are not only homotolerant to LPS but are heterotolerant to alternative pathogen-associated molecular pattern ligands, such as mycobacterial protein extract (Mycobacterium tuberculosis). Specifically, while M. tuberculosis protein extract induces secretion of IL-1β, TNF-α and IL-6 in unprimed BMDC, LPS-primed BMDC fail to secrete these cytokines in response to M. tuberculosis. We propose that LPS priming of BMDC, by exposure to high doses of LPS for 24 hr, stabilizes their tolerogenicity rather than promoting immunogenicity, and does so by multiple mechanisms, namely (i) generation of tolerogenic apoptotic BMDC through CD14:NFATc signalling; (ii) reduction of NF-κB and IRF3 signalling and downstream pro-inflammatory cytokine production; and (iii) blockade of inflammasome activation

Comparative antibacterial potential of selected aldehyde-based biocides and surfactants against planktonic Pseudomonas fluorescens

The antimicrobial efficacy of two aldehydebased biocides (glutaraldehyde, GTA, and orthophthalaldehyde, OPA) and two surfactants (cetyltrimethyl ammonium bromide, CTAB, and sodium dodecyl sulphate, SDS) was tested against planktonic Pseudomonas fluorescens. The antimicrobial effects were evaluated by respiratory activity as a measure of the oxygen uptake rate, adenosine triphosphate (ATP) release, outer membrane proteins (OMP) expression and cellular colour changes. The results were compared with the bacterial characteristics without chemical treatment. Tests in the presence of bovine serum albumin (BSA), in order to mimic a disinfection process in the real situation under dirty conditions, were performed according to the European Standard EN-1276. P. fluorescens was completely inactivated with OPA (minimum bactericidal concentration, MBC = 0.5 mM) and CTAB (MBC = 5 mM) and was resistant to GTA and SDS. Only CTAB promoted cellular disruption and consequent ATP release. The antimicrobial action of the chemicals tested was significantly reduced when BSA was introduced into the bacterial cultures, increasing markedly the MBC values. Additionally, the presence of BSA acted as a disruption protective agent when CTAB was applied and stimulated the bacterial respiratory activity when lower concentrations of SDS were tested. The OMP of the bacterial cells was affected by the application of both surfactants. OMP expression remained unaltered after biocide treatment. Bacterial colour change was noticed after treatment with biocides and surfactants. In summary, P. fluorescens was extremely resistant to GTA and SDS, with antimicrobial action being quenched markedly by the reaction with BSA.Instituto de Biotecnologia e Química Fina (IBQF).Fundação para a Ciência e a Tecnologia (FCT) - (Project CHEMBIO - POCI/BIO/61872/2004

Domain wall fermions for planar physics

In 2+1 dimensions, Dirac fermions in reducible, i.e. four-component representations of the spinor algebra form the basis of many interesting model field theories and effective descriptions of condensed matter phenomena. This paper explores lattice formulations which preserve the global U(2N) symmetry present in the massless limit, and its breakdown to U(N)xU(N) implemented by three independent and parity-invariant fermion mass terms. I set out generalisations of the Ginsparg-Wilson relation, leading to a formulation of an overlap operator, and explore the remnants of the global symmetries which depart from the continuum form by terms of order of the lattice spacing. I also define a domain wall formulation in 2+1+1d, and present numerical evidence, in the form of bilinear condensate and meson correlator calculations in quenched non-compact QED using reformulations of all three mass terms, to show that U(2N) symmetry is recovered in the limit that the domain-wall separation L tends to infinity. The possibility that overlap and domain wall formulations of reducible fermions may coincide only in the continuum limit is discussed

An assessment of the Literature on Cause-Related Marketing: Implications for International Competitiveness and Marketing Research

Purpose: A substantial, albeit scattered, body of research evidence is accumulating in the cause-related marketing (CRM) research stream. Thus, there is a need of a systematic overview of extant literature to map and holistically understand the CRM domain. Design/methodology/approach: To address this issue and make progress in this important area, the authors systematically review and critically examine the state of academic research on CRM. Findings: Based on a systematic review of 105 journal articles published over the past 30 years, the results reveal that CRM research is a vibrant and rapidly growing domain in the broader marketing field. This assessment exercise also shows that the current state of knowledge about CRM is characterized by persisting knowledge gaps, conflicting empirical results, theoretical inconsistencies, as well as by the absence of international marketing research on the CRM domain. Originality/value: Therefore, the authors critically evaluate the extant CRM research with the aim of increasing its coherence, quality, scope, impact and international dimension. Based on this evaluation, the authors develop an ambitious research agenda that addresses a number of promising research paths embracing different international perspectives. Finally, the authors discuss the contributions to the literature and the implications for both academics and practitioners
