An exploratory case study of aspect‐oriented metrics for fault proneness, content and fixing effort prediction
Authors: Elish Mahmoud O. , AL‐Rahman AL‐Khiaty Mojeeb , Alshayeb Mohammad 
Published: March 2013

PurposeThe purpose of this paper is to investigate the relationships between some aspect‐oriented metrics and aspect fault proneness, content and fixing effort.Design/methodology/approachAn exploratory case study was conducted using an open source aspect‐oriented software consisting of 76 aspects, and 13 aspect‐oriented metrics were investigated that measure different structural properties of an aspect: size, coupling, cohesion, and inheritance. In addition, different prediction models for aspect fault proneness, content and fixing effort were built using different combinations of metrics' categories.FindingsThe results obtained from this study indicate statistically significant correlation between most of the size metrics and aspect fault proneness, content and fixing effort. The cohesion metric was also found to be significantly correlated with the same. Moreover, it was observed that the best accuracy in aspect fault proneness, content and fixing effort prediction can be achieved as a function of some size metrics.Originality/valueFault prediction helps software developers to focus their quality assurance activities and to allocate the needed resources for these activities more effectively and efficiently; thus improving software reliability. In literature, some aspect‐oriented metrics have been evaluated for aspect fault proneness prediction, but not for other fault‐related prediction problems such as aspect fault content and fixing effort.
A framework for Six‐Sigma driven RFID‐enabled supply chain systems
Authors: Zare Mehrjerdi Yahia 
Published: March 2013

PurposeThis paper aims to propose a new framework for selecting strategies from the pools of RFID strategies, Six‐Sigma strategies and supply chain strategies. To gain a better understanding of the proposed model, three case studies are investigated and all related strategies are presented and discussed.Design/methodology/approachThis article proposes a new framework for Six‐Sigma driven RFID‐enabled supply chain systems. Theory building is comprised of four parts where each part is discussed clearly in the content of the article. However, it is through such tools that management can identify new systems for matching the needs of his/her organization with all of the right strategies.FindingsIn a journey to business excellence, an organization is successful if specific goals for critical processes of the organization are identified. The quality management programs implemented can modernize and simplify activities towards the ultimate goal of the business. To do so, this author's discussions on Six‐Sigma strategies, supply chain strategies, and radio frequency identification are converted into a framework that can be used for developing an appropriate model for organizational strategy selection. There are some cases in the literature that can support such a model building and framework identification. Three of such cases are presented for the readers' familiarity with the subject.Practical implicationsThe use of these three methodologies can bring significant changes to an organization. This can be done by taking into consideration the key strategies of supply chain management, Six‐Sigma, and RFID playing a big role in the success of the organization.Originality/valueFor each methodology considered, strategies are examined and a framework based upon such methodologies is proposed. Cases supporting the proposed framework are reviewed from the literature for clarification purposes.
The common ground of relationships and exchange: towards a contractual foundation of marketing
Authors: Ehret Michael , Haase Michaela 
Published: March 2013

PurposeThe aim of this paper is to argue for an explicit foundation of market exchange on person‐to‐person relationships as an alternative to the foundation on person‐to‐goods relationship underlying the exchange model inherited from neoclassical economics and classical contract law and used in a large significant share of marketing studies.Design/methodology/approachThe paper provides a unifying theoretical framework to the analysis of transactions and relationships that links institutional approaches from economics, sociology, and law.FindingsRelational contract theory provides a common ground for phenomena studied by both traditional exchange‐based and relationship marketing approaches. Relational contract theory conceives all types of market exchange as based on person‐to‐person relationships and provides an anchor for institutional, social and economic approaches in marketing.Research limitations/implicationsThe concept of transaction provides a common foundation for the analysis of marketing phenomena that holds in diverse environments, including arms‐length transactions and close‐linked relationships. It provides an interface between marketing theory on the one hand and institutional, social and economic disciplines on the other.Practical implicationsContracts specify how the parties to a transaction can realize action options opened up by property rights arrangements. Contracting strategy is the vital backbone of an industrial service strategy. Sound design of business models starts with the identification of the optimal owner of a resource, i.e. the actor who is in the best position to manage uncertainties or take on responsibilities associated with resource use.Originality/valueThis is the first investigation of a contractual foundation of marketing theory. It embeds the concept of exchange in an institutional framework and adapts it to the evolving business reality shaped by co‐operating firms and the rising share of services in value creation.
Factors affecting new product post-adoption behavior in a major US automotive supply chain: an examination of antecedents to technology internalization
Authors: Hong-kit Yim Frederick , Forman Howard , Kwa Hyokjin 
Published: March 2013

Purpose– Given the importance of technology implementation and usage in managing and leveraging supply chains and the associated difficulties of diffusing information technology (IT) within and across organizations, little research has been conducted to understand the antecedents of technology adoption, particularly in the supply chain context. The purpose of this paper is to extend the understanding of how organizational factors affect post-adoption behaviors, a process collectively defined as internalization.Design/methodology/approach– A mail survey of 413 supply chain members of a major US automotive company was conducted to test the model.Findings– The study finds that relative cost, supply chain orientation, and task-technology fit have a direct effect on extended technology usage or internalization of the technology.Research limitations/implications– Although the study sample was collected from the supply chain base of the largest automotive manufacturer in the world, its generalizability is limited as it represents a single tier of one supply chain. The sample consists of suppliers from North America, which restricts generalizability to companies in that geographic area.Practical implications– The research findings suggest that managers can influence post-adoption behaviors through seamlessly fitting the technology to the employee's tasks, communicating the advantages of utilizing the technology to its users, and developing an orientation of supply chain activities.Originality/value– While previous research focuses more on technology adoption, the present study extends previous research by looking into technology internalization, a process related to the effective and consistent use of a technology over time.
The academic‐professional divide: generating useful research and moving it to practice
Authors: Wofford Larry , Troilo Michael 
Published: March 2013

PurposeThe aim of this study is to examine the divide between academicians and professionals in the applied field of real estate in the USA and the impact of this divide on the use of best evidence by professionals. Its purpose is to introduce the concept of evidence‐based management to the discipline of real estate, to propose a framework for gathering best evidence, and to develop a stream of translational research to bridge the academic‐professional divide.Design/methodology/approachThe paper takes an interdisciplinary conceptual approach regarding the gap between academic theory and practice, and its resolution. The authors apply the idea of best evidence and its management from the field of medicine to construct guidelines appropriate for real estate scholars and practitioners.FindingsThe paper offers a framework as a starting point for handling the academic‐professional divide. The paper borrows the concept of translational research from medicine to discuss how basic theoretical knowledge may be communicated to real estate professionals to improve performance.Originality/valueThe main contribution is to suggest means for building relevant, practical knowledge in real estate. Application of the evidence‐based method can make the work of researchers more rewarding by solving pragmatic, real‐world concerns. Real estate professionals can allocate scarce resources more effectively by following the evidence‐based approach. The use of evidence separates fact from fiction and enables prioritization of concerns.
Landlord and tenant update – hard times, strict compliance
Authors: Dowden Malcolm , Humphreys Emma 
Published: March 2013

PurposeDifficult economic and trading conditions make lease break options a point of significant legal tension between commercial landlords and tenants. For a tenant, the ability to break a lease provides a means of controlling costs and an exit from liabilities. For landlords, the loss of a tenant's covenant means an immediate adverse effect on the reversionary value of the property. The purpose of this paper is to examine recent English court rulings to highlight the need for strict compliance with break conditions if a tenant is to succeed in ending its liabilities.Design/methodology/approachThe paper discusses recent rulings to assess the extent to which judicial interpretation of break clauses continues to favour landlords, and whether landlords' conduct in negotiations or correspondence leading up to the exercise of a tenant's break option might engage concepts such as estoppel to bind the landlord to a particular level of compliance or breach.FindingsThe paper concludes that the English court continues to apply a strict approach to compliance with break conditions, and that it remains the tenant's responsibility both to determine what needs to be done by way of compliance and to ensure that those steps are taken.Originality/valueThe authors place the most recent rulings on the perennially vexed issue of compliance with break conditions into a broader context, demonstrating that the judicial approach remains firmly based on the principle that a break option is negotiated for the tenant's benefit, and that any conditions precedent to exercise are highly likely to be construed against the tenant who agreed to a break conditional on anything other than service of notice.
The discounted cash flow model for property valuations: quarterly cash flows
Authors: French Nick 
Published: March 2013

PurposeThere are three approaches to valuation: cost, market and income. As a subset to the income approach, the investment method looks at the pricing of assets that produce income over an investment holding period. The discounted cash flow (DCF) technique or model can be developed to look at the cash flows on a quarterly basis to reflect the actual receipt of the cash flows. The aim of this paper is to give an overview of the DCF quarterly model.Design/methodology/approachThis education briefing is an overview of the DCF quarterly model.FindingsThe DCF quarterly model can be seen to produce estimates of market value.Practical implicationsAs the use of DCF is developed and expanded, it is useful to be able to model the cash flows appropriately.Originality/valueThis is a review of existing models.
Human Geography trains diverse perspectives on global development
Authors: Ahamer Gilbert 
Published: March 2013

PurposeEducation for equity in global development and cultural diversity calls for professional capacity building to perceive diverse perspectives on complex procedures of globalisation. The discipline of human geography is such a “provider of perspectives”. The purpose of this paper is to propose a historic series of how theories of geography and human development have emerged.Design/methodology/approachThis paper contributes to education and training by proposing a historic series of how theories of geography and human development have emerged.FindingsThe outcomes of this analysis of geographic paradigms offer options for the management of multicultural education in development. A critical synopsis and a combination of various paradigms on global development seem most promising for a holistic and comprehensive understanding of globalisation.Research limitations/implicationsIn particular, recent developments in human geography exhibit rapidly changing paradigms (ironically called “the Latin America of sciences”) and are hence difficult to systematise.Practical implicationsSpaces are understood to be communicational spaces, the substrate of which is enabling communication technologies. The theoretical contemplations of this paper permit to design learning environments, learning styles and related technologies.Social implicationsPerception and understanding of contradicting theories on global (economic and human) development facilitate education fostering multiple cultures of understanding. The author's own professional experience shows that only esteem for all paradigms can provide the full picture. Success means “collective production of meaning”.Originality/valueUnderstanding history frees us to reach future consensus.
Influence of cornicle droplet secretions of the cabbage aphid, Brevicoryne brassicae, on parasitism behavior of naïve and experienced Diaeretiella rapae
Authors: Moayeri Hamid R. S. , Rasekh Arash , Enkegaard Annie 
Published: March 2013

AbstractInsects have evolved amazing methods of defense to ward off enemies. Many aphids release cornicle secretions when attacked by predators and parasitoids. These secretions contain an alarm pheromone that alerts other colony members of danger, thereby providing indirect fitness benefits to the releaser. In addition, contact with cornicle secretions could also threaten an attacker and could provide direct fitness to the releaser. However, cornicle secretions may also be recruited as a kairomonal cue by aphid natural enemies. In this study, we investigated the effect of the cornicle droplet volatiles of the cabbage aphid, Brevicoryne brassicae (L.), on the host‐searching behavior of naïve and experienced female Diaeretiella rapae (M’Intosh) parasitoids in olfactometer studies. In addition, we evaluated the role of B. brassicae cornicle droplets on the oviposition preference of the parasitoid in a two‐choice bioassay. Naïve females did not exhibit any preference between volatiles from aphids secreting cornicle droplets over non‐secreting aphids, while experienced parasitoids exploited the secretions in their host location. Experienced females were also able to choose volatiles from both secreting and non‐secreting aphids over clean air, while this ability was not observed in naïve females. Although secretion of cornicle droplets did not influence the percentage of first attack in either naïve or experienced females, the success of attack (i.e. resulting in a larva) was significantly different between secreting and non‐secreting aphids in the case of experienced parasitoids.
Masquerading in the U.S. Capital Markets: The Dark Side of Maintaining an Institution
Authors: Clark Cynthia E. , Newell Sue 
Published: March 2013

AbstractThis article examines the work of professional service firms (PSFs) in their relationships with public corporations; work that is designed to ensure that investors and potential investors have information that will enable them to participate in the capital markets. Using an institutional theory lens, we view these efforts by PSFs as institutional maintenance work and specifically analyze their work related to policing (i.e., rating), enabling (i.e., tutoring), and embedding and routinizing (i.e., collaborating) that helps to support the capital market as a core institution in society. We illustrate how there is a “dark” side to each of these forms of institutional work that exists because of ongoing conflicts of interest within and between their work practices. This dark side has the unintended consequence of producing often biased information or information unavailable to many. When a crisis brings this bias to light, some repair is introduced but often not enough to alleviate the distortion. Our contribution is, therefore, to shed light on the dark side of institutional maintenance work and to explore why repair is increasingly necessary, but often only partially effective.
Ureteroscopic management of upper tract urothelial carcinoma (UTUC) in patients with Lynch Syndrome (hereditary nonpolyposis colorectal cancer syndrome)
Authors: Hubosky Scott G. , Boman Bruce M. , Charles Sarah , Bibbo Marluce , Bagley Demetrius H. 
Published: March 2013

Objectives
To report our experience with ureteroscopic laser ablation of upper tract urothelial carcinoma (UTUC) in patients with Lynch Syndrome (LS), as defined by a documented germline mutation in the MSH‐2 gene.
To increase awareness among urologists about UTUC in this unique patient population and refer to genetic counselling when appropriate.
Patients and Methods
Demographic, clinical and pathological data on 13 consecutive patients with UTUC and documented MSH‐2 mutation comprising 15 involved renal units were retrospectively collected.
Ureteroscopic evaluations involved biopsy and laser treatment with combination holmium/neodymium yttrium aluminum garnet (YAG) lasers.
Tumours were graded from 1 to 3 according to the 1973 World Health Organisation classification by a single pathologist evaluating cell block preparations.
Results
The mean patient age at initial presentation was 56.5 years, with six of 13 patients having metachronous bilateral UT disease.
The mean follow‐up was 59 months with a mean number of surveillances of 12. Of 15 affected renal units, 10/15 (67%) of initial tumours involved the ureter with mean lesion size of 17.5 mm, while five of 15 (33%) involved the intrarenal collecting system with mean lesion size of 25 mm.
Ureteroscopy cleared 13/15 (87%) lesions and four of those 13 (31%) needed staged procedures. Renal preservation rate was 14/15 (93%) with one nephroureterectomy and one segmental ureterectomy performed.
One patient developed metastatic UTUC after 40 months surveillance. No patient presented with bladder tumours but seven of the 13 (54%) developed them within 10 months of the initial ureteroscopy.
Conclusions
Patients with LS who develop UTUC present at younger ages and appear to be more likely to have bilateral UT disease over their lifetimes vs sporadic UTUC patients.
Ureteroscopic laser ablation offers a good renal preservation rate with reasonable cancer control in patients willing to undergo endoscopic surveillance.
Development of new bladder tumours is common.
Cellular differentiation and individuality in the ‘minor’ multicellular taxa
Authors: Herron Matthew D. , Rashidi Armin , Shelton Deborah E. , Driscoll William W. 
Published: March 2013

ABSTRACTBiology needs a concept of individuality in order to distinguish organisms from parts of organisms and from groups of organisms, to count individuals and compare traits across taxa, and to distinguish growth from reproduction. Most of the proposed criteria for individuality were designed for ‘unitary’ or ‘paradigm’ organisms: contiguous, functionally and physiologically integrated, obligately sexually reproducing multicellular organisms with a germ line sequestered early in development. However, the vast majority of the diversity of life on Earth does not conform to all of these criteria. We consider the issue of individuality in the ‘minor’ multicellular taxa, which collectively span a large portion of the eukaryotic tree of life, reviewing their general features and focusing on a model species for each group. When the criteria designed for unitary organisms are applied to other groups, they often give conflicting answers or no answer at all to the question of whether or not a given unit is an individual. Complex life cycles, intimate bacterial symbioses, aggregative development, and strange genetic features complicate the picture. The great age of some of the groups considered shows that ‘intermediate’ forms, those with some but not all of the traits traditionally associated with individuality, cannot reasonably be considered ephemeral or assumed transitional. We discuss a handful of recent attempts to reconcile the many proposed criteria for individuality and to provide criteria that can be applied across all the domains of life. Finally, we argue that individuality should be defined without reference to any particular taxon and that understanding the emergence of new kinds of individuals requires recognizing individuality as a matter of degree.
Glucocorticoid‐induced osteoporosis: lessons from Cushing's syndrome
Authors: Tóth Miklós , Grossman Ashley 
Published: March 2013

SummaryGlucocorticoid‐induced osteoporosis (GIO) is the most frequent form of secondary bone disorders. Most of our knowledge on its pathogenesis and treatment has been obtained by investigating patients treated with exogenous glucocorticoids. This review will focus on the bone disorder in endogenous Cushing's syndrome, updating recent advances in its pathophysiology, diagnostic aspects and the various predictors which are important in determining bone mineral density (BMD) and fracture risk. We now know strong evidence that beside BMD, bone microarchitecture, one of the most important elements of bone quality, is a key factor in determining fracture risk. Recently, two new methods (spinal deformity index and trabecular bone score) have been shown to be useful markers of bone microarchitecture in GIO. Investigations of GIO in endogenous Cushing's syndrome have also contributed to our understanding on its natural history and reversibility. Relying on recently published guidelines for management of exogenous GIO, a short list of suggestions is provided regarding the optimal diagnostic and therapeutic approach to patients with endogenous GIO.
Impact of new genomic tools on the practice of clinical genetics in consanguineous populations: the Saudi experience
Authors: Alkuraya FS 
Published: March 2013

AbstractConsanguinity is practiced by around one tenth of the world population but its global distribution is far from uniform. In countries where consanguinity is common, a corresponding increase in the frequency of autosomal recessive diseases is usually observed owing to increased risk of homozygosity for ancestral haplotypes (autozygosity or identity by descent) that harbor pathogenic alleles. The burden of these diseases becomes more apparent as the healthcare system makes gains in its fight against communicable diseases in these countries. Recent advances in molecular genetics make it possible to leverage the mechanism by which consanguinity predisposes to the occurrence of autosomal recessive diseases in order to uncover the causal mutations at an efficient and cost‐effective way compared to outbred populations. The identification of these mutations at an unprecedented scale has the potential to significantly reshape the practice of clinical genetics in these populations and to offer opportunities for innovative public health policies. This review discusses the impact that new genomic tools have had on a sample patient population and how they can inform future public health policies in ways that might be relevant to other consanguineous populations.
