NONCOMMUTATIVE REAL ALGEBRAIC GEOMETRY OF KAZHDAN’S PROPERTY (T)
Authors: Ozawa Narutaka 
Published: July 2014

It is well known that a finitely generated group ${\rm\Gamma}$ has Kazhdan’s property (T) if and only if the Laplacian element ${\rm\Delta}$ in $\mathbb{R}[{\rm\Gamma}]$ has a spectral gap. In this paper, we prove that this phenomenon is witnessed in $\mathbb{R}[{\rm\Gamma}]$. Namely, ${\rm\Gamma}$ has property (T) if and only if there exist a constant ${\it\kappa}>0$ and a finite sequence ${\it\xi}_{1},\ldots ,{\it\xi}_{n}$ in $\mathbb{R}[{\rm\Gamma}]$ such that ${\rm\Delta}^{2}-{\it\kappa}{\rm\Delta}=\sum _{i}{\it\xi}_{i}^{\ast }{\it\xi}_{i}$. This result suggests the possibility of finding new examples of property (T) groups by solving equations in $\mathbb{R}[{\rm\Gamma}]$, possibly with the assistance of computers.
‘Sound Effects (O.K., Music)’: Steve Reich and the Visual Arts in New York City, 1966–1968
Authors: COLE ROSS 
Published: July 2014

AbstractThis article explores Steve Reich's relationship with New York City's downtown artworld during the latter half of the 1960s, aiming to nuance aspects of early minimalism by tracing diachronic connections with the Park Place gallery, the exhibitionAnti-Illusion: Procedures/Materials, Richard Serra, Sol LeWitt, and movements such as process art and conceptualism. I suggest that, rather than revealing Reich's prior compositional philosophy, his 1968 treatise ‘Music as a Gradual Process’ demonstrated aesthetic cohesion with the stance of a particular milieu, mirroring a broader linguistic turn in contemporaneous art and revealing a certain discrepancy between theory and praxis. Drawing on newspaper reception, I explore Reich's compositions fromMelodica(1966) toPendulum Music(1968), arguing that these pieces gained both aesthetic value and institutional credibility through being understood in relation to concurrent artwork and ideas, affording productive horizons of expectation.
Beware the Lamb: Staging Bach's Passions
Authors: VARWIG BETTINA 
Published: July 2014

AbstractThis article considers the twentieth- and twenty-first-century practice of presenting Johann Sebastian Bach's Passion compositions on stage, in light of recent debates about performativity, presence and liveness. By tracing the history of such stagings from Ferruccio Busoni's plans in the 1920s to contemporary versions by Peter Sellars, Alain Platel, and others, I explore the increasing tendency to turn these canonical works into politically or aesthetically relevant events. Through a close reading of the critical reception of each production, I show how stagings have the capacity to challenge productively our easy familiarity with these pieces outside their initial liturgical setting. Unlike a standard concert presentation, staged performances tend to confront audiences more immediately with the violent imagery and spiritual demands of the Passions, thereby continually renewing the dialogue between Bach's works and later audiences. The article thus offers a contribution to an anthropological enquiry into the present-day cult of Bach and the particular forms of aesthetic pleasure that classical music affords its twenty-first-century devotees.
Theory of rapid force spectroscopy
Authors: Bullerjahn Jakob T. , Sturm Sebastian , Kroy Klaus 
Published: July 2014

AbstractIn dynamic force spectroscopy, single (bio-)molecular bonds are actively broken to assess their range and strength. At low loading rates, the experimentally measured statistical distributions of rupture forces can be analysed using Kramers’ theory of spontaneous unbinding. The essentially deterministic unbinding events induced by the extreme forces employed to speed up full-scale molecular simulations have been interpreted in mechanical terms, instead. Here we start from a rigorous probabilistic model of bond dynamics to develop a unified systematic theory that provides exact closed-form expressions for the rupture force distributions and mean unbinding forces, for slow and fast loading protocols. Comparing them with Brownian dynamics simulations, we find them to work well also at intermediate pulling forces. This renders them an ideal companion to Bayesian methods of data analysis, yielding an accurate tool for analysing and comparing force spectroscopy data from a wide range of experiments and simulations.

AbstractOver the last four decades, molecular cloning has evolved tremendously. Efficient products allowing assembly of multiple DNA fragments have become available. However, cost-effective tools for engineering antibodies of different specificities, isotypes and species are still needed for many research and clinical applications in academia. Here, we report a method for one-step assembly of antibody heavy- and light-chain DNAs into a single mammalian expression vector, starting from DNAs encoding the desired variable and constant regions, which allows antibodies of different isotypes and specificity to be rapidly generated. As a proof of principle we have cloned, expressed and characterized functional recombinant tumor-associated antigen-specific chimeric IgE/κ and IgG1/κ, as well as recombinant grass pollen allergen Phl p 7 specific fully human IgE/λ and IgG4/λ antibodies. This method utilizing the antibody expression vectors, available at Addgene, has many applications, including the potential to support simultaneous processing of antibody panels, to facilitate mechanistic studies of antigen-antibody interactions and to conduct early evaluations of antibody functions.

AbstractThe inability of vaccines to retain sufficient thermostability has been an obstacle to global vaccination programs. To address this major limitation, we utilized carbohydrate-based ice recrystallization inhibitors (IRIs) to eliminate the cold chain and stabilize the potency of Vaccinia virus (VV), Vesicular Stomatitis virus (VSV) and Herpes virus-1 (HSV-1). The impact of these IRIs was tested on the potency of the viral vectors using a plaque forming unit assay following room temperature storage, cryopreservation with successive freeze-thaw cycles and lyophilization. Viral potency after storage with all three conditions demonstrated that N-octyl-gluconamide (NOGlc) recovered the infectivity of shelf stored VV, 5.6 Log10 PFU mL−1 during 40 days and HSV-1, 2.7 Log10 PFU mL−1 during 9 days. Carbon-linked antifreeze glycoprotein analogue ornithine-glycine-glycine-galactose (OGG-Gal) increases the recovery of VV and VSV more than 1 Log10 PFU mL−1 after 10 freeze-thaw cycles. In VSV, cryostorage with OGG-Gal maintains high infectivity and reduces temperature-induced aggregation of viral particles by 2 times that of the control. In total, OGG-Gal and NOGlc preserve virus potency during cryostorage. Remarkably, NOGlc has potential to eliminate the cold chain and permit room temperature storage of viral vectors.
Phonetic Imitation by Young Children and Its Developmental Changes
Authors: Nielsen Kuniko 
Published: July 2014

PurposeIn the current study, the author investigated the developmental course of phonetic imitation in childhood, and further evaluated existing accounts of phonetic imitation.MethodSixteen preschoolers, 15 third graders, and 18 college students participated in the current study. An experiment with a modified imitation paradigm with a picture-naming task was conducted, in which participants' voice-onset time (VOT) was compared before and after they were exposed to target speech with artificially increased VOT.ResultsExtended VOT in the target speech was imitated by preschoolers and 3rd graders as well as adults, confirming previous findings in phonetic imitation. Furthermore, an age effect of phonetic imitation was observed; namely, children showed greater imitation than adults, whereas the degree of imitation was comparable between preschoolers and 3rd graders. No significant effect of gender or word specificity was observed.ConclusionsYoung children imitated fine phonetic details of the target speech, and greater degree of phonetic imitation was observed in children compared to adults. These findings suggest that the degree of phonetic imitation negatively correlates with phonological development.

Authors: Kundermann S. , Portuondo‐Campa E. , Lecomte S. 
Published: July 2014

A robust optical frequency comb is realised with an Origami‐10 mode‐locked femtosecond laser from Onefive GmbH generating a 100 MHz pulse train at a centre wavelength of 1047 nm. The carrier‐envelope offset frequency has been stabilised to a record level contributing to relative fluctuations of the optical carrier frequency of 1.1 × 10−18 at 1 s and averaging down to the 10−22 level at 10 000 s. Cycle‐slip free carrier‐envelope offset frequency stabilisation has been routinely achieved over 10 h. Ultra‐low relative intensity noise has been measured as well and makes such a system very attractive for demanding applications where low noise and high reliability are requested.
Major alteration in coxsackievirus B3 genomic RNA structure distinguishes a virulent strain from an avirulent strain
Authors: Prusa Jerome , Missak Johanna , Kittrell Jeff , Evans John J. , Tapprich William E. 
Published: July 2014

AbstractCoxsackievirus B3 (CV-B3) is a cardiovirulent enterovirus that utilizes a 5′ untranslated region (5′UTR) to complete critical viral processes. Here, we directly compared the structure of a 5′UTR from a virulent strain with that of a naturally occurring avirulent strain. Using chemical probing analysis, we identified a structural difference between the two 5′UTRs in the highly substituted stem-loop II region (SLII). For the remainder of the 5′UTR, we observed conserved structure. Comparative sequence analysis of 170 closely related enteroviruses revealed that the SLII region lacks conservation. To investigate independent folding and function, two chimeric CV-B3 strains were created by exchanging nucleotides 104–184 and repeating the 5′UTR structural analysis. Neither the parent SLII nor the remaining domains of the background 5′UTR were structurally altered by the exchange, supporting an independent mechanism of folding and function. We show that the attenuated 5′UTR lacks structure in the SLII cardiovirulence determinant.
Hepatic Steatosis Is Prevalent in Stillborns Delivered to Women With Diabetes Mellitus
Authors: Patel Kalyani R. , White Frances V. , Deutsch Gail H. 
Published: July 2014

ABSTRACTObjective:Maternal diabetes is a risk factor for pregnancy complications, including stillbirth and macrosomia. Evolving data suggest that diabetes during pregnancy also has long‐term consequences for offspring, putting them at risk for obesity and the metabolic syndrome in childhood. Because nonalcoholic fatty liver disease is known to occur in adults and children with insulin resistance, we hypothesized that altered lipid metabolism in fetuses of diabetic mothers may manifest with hepatic steatosis.Methods:We undertook a retrospective autopsy study to compare the presence and degree of hepatic steatosis between stillborns delivered to women with pregestational or gestational diabetes mellitus (gestational age 20–40 weeks; n = 33) and age‐matched nondiabetic control stillbirth cases (n = 48), the latter enriched for maternal obesity, macrosomia, and similar cause of demise.Results:Histopathologic hepatic steatosis was significantly more prevalent and severe in the diabetic subjects (26/33, 78.8%) than in the controls (8/48, 16.6%) (P < 0.001). Within the diabetic cohort, the severity of steatosis was related directly to gestational age, birth weight, and liver weight, with no correlation of presence or severity of steatosis in the control group to maternal or fetal factors, including maternal body mass index or fetal macrosomia. Although macrosomic stillborns were more common in diabetic women with %hemoglobin A1c >6 and body mass index >30 kg/m2, fetal steatosis was independent of glycemic control, maternal obesity, type of diabetes, ethnicity, or fetal sex in our cohort.Conclusions:This study is the first to our knowledge to demonstrate a specific association between fetal hepatic steatosis and maternal diabetes.
Customer requirements based ERP customization using AHP technique
Authors: Parthasarathy Sudhaman , Daneva Maya 
Published: July 2014

Purpose– Customization is a difficult task for many organizations implementing enterprise resource planning (ERP) systems. The purpose of this paper is to develop a new framework based on customers’ requirements to examine the ERP customization choices for the enterprise. The analytical hierarchy process (AHP) technique has been applied complementarily with this framework to prioritize ERP customization choices.Design/methodology/approach– Based on empirical literature, the paper proposed an ERP customization framework anchored on the customer's requirements. A case study research method was used to evaluate the applicability of the framework in a real-life setting. In a case study with 15 practitioners working on the vendor's and the client's sides in an ERP implementation, the paper applied the framework jointly with the AHP technique to prioritize the feasible customization choices for ERP implementation.Findings– The paper demonstrates the applicability of the framework in identifying the various feasible choices for the client organization to consider when they decide to customize their selected ERP product.Research limitations/implications– Further case studies need to be carried out in various contexts to acquire knowledge about the generalizability of the observations. This will also contribute to refining the proposed ERP customization framework.Practical implications– Very few literature sources suggest methods for exploring and evaluating customization options in ERP projects from requirements engineering perspective. The proposed framework helps practitioners and consultants anchor the customization decisions on the customer's requirements and use a well-established prioritization technique, AHP, to identify the feasible customization choices for the implementing enterprise.Originality/value– No previously published research studies provide an approach to prioritize customization choices for ERP anchored on the customer's requirements.
An ECRS-based line balancing concept: a case study of a frozen chicken producer
Authors: Ongkunaruk Pornthipa , Wongsatit Wimonrat 
Published: July 2014

Purpose
– The purpose of this paper is to improve the productivity of a large-sized frozen chicken manufacturer in Thailand. It analyses the production process based on work study principles and identifies the bottleneck operation. It develops three models for the chicken preparation process.

Design/methodology/approach
– First, analyse the current production system by collecting the cycle time of all operations in the production process based on work study principles. Then, design the production network and identify the bottleneck operation. After that, three methods – based on line balancing (LB), theory of constraints, and JIT concepts or ECRS (eliminate, combine, rearrange and simplify) – are proposed and implemented in the actual production line.

Findings
– With the ECRS concept, the authors implement combine by combining two stations into one station, such as handling and weighing, or weighing batter and mixing it with chicken. Then, Simplify is implemented at job E, or transporting chicken using a cart instead of walking. This method can improve the cycle time and reduce the number of employees. It can increase the line efficiency by up to 94.20 per cent, reduce the number of employees by 14 persons, and reduce the labour cost by 356,160 baht/year.

Originality/value
– Most agro-industry manufacturing processes are labour intensive. Thus, production LB can help increase productivity and reduce costs. The authors found that the case study company designed the production line without aligning it with the production network. A simple improvement can be made by adjusting the sequence of the work. In addition, the current production line was not lean. Implementation of the ECRS concept to improve production can reduce the waiting time and simplify the job.
Business process redesign project success: the role of socio-technical theory
Authors: Xiang Junlian , Archer Norm , Detlor Brian 
Published: July 2014

Purpose
– The purpose of this paper is to seek to advance business process redesign (BPR) project research through the generation and testing of a new research model that utilizes formative constructs to model complex BPR project implementation issues. Instead of looking at management principles, the paper examines the activities of improving business processes from the project perspective.

Design/methodology/approach
– A survey of 145 managers and executives from medium and large-sized USA and Canadian companies was used to validate the model.

Findings
– The model, based on socio-technical theory, includes three implementation components (change management, process redesign, and information and communication technology infrastructure improvement), and links the effects of these components to BPR project outcomes. The empirical findings indicated that all three implementation components had a significant impact on BPR project success, with change management having the greatest effect. Interestingly, the results also showed that productivity improvement was no longer the main focus of companies carrying out BPR projects; instead, improvement in operational and organizational quality was more important.

Research limitations/implications
– The main limitation of this study is its generalizability with respect to company size and organizational culture. The sample in this study was drawn from medium- and large-sized companies in Canada and the USA, but small-sized organizations were excluded from this study due to their distinct features (e.g. superior flexibility or ability to reorient themselves quickly). Also, this study controlled the variable of organizational culture by limiting respondents to Canada and US companies. It would be very interesting to investigate BPR project implementations in other countries where the organizational working culture may be different.

Practical implications
– Based on the findings of this study, BPR practitioners can refer to the three BPR project implementation components and then prioritize and sequence the tasks in a BPR project to achieve their preset BPR goals.

Originality/value
– This is the first study which utilizes formative constructs to validate the important BPR project components.
A cross-cultural study of managerial skills and effectiveness
Authors: C. Hoffman Richard , M. Shipper Frank , A. Davy Jeanette , M. Rotondo Denise 
Published: July 2014

Purpose– The purpose of this study is to examine the relationship between managerial skills and effectiveness in a cross-cultural setting to determine their applicability.Design/methodology/approach– Data from 7,606 managers in 5 countries from a large multinational firm were analyzed using structural equation modeling to assess all relationships simultaneously and reduce error effects.Findings– The results support the cross-cultural validity of the model of managerial skills-effectiveness. Few cross-cultural differences were found. Interactive skills had greater positive impact on attitudes than initiating skills. Pressuring skills had a negative impact on attitudes. None of the skill sets were related to job performance.Research limitations/implications– Using a single firm and industry to control for other cultural levels may limit the generalizability of the results. Only three skill sets were assessed and one coarse-grained measure of culture was used. These factors may account for the few cultural differences observed.Practical implications– Training programs for managers going overseas should develop both interactive and initiating skills sets, as both had a positive impact on attitudes across cultures.Originality/value– The model of managerial skills and effectiveness was validated across five cultures. The use of structural equation modeling ensures that the results are not an artifact of the measures and represents a more direct test for cross-cultural differences. Managing successfully across cultures may require fewer unique skills, with more emphasis placed on using basic management skills having positive impact.
Information security governance implementation within Ghanaian industry sectors
Authors: Yaokumah Winfred 
Published: July 2014

Purpose
– The purpose of this study is to assess the levels of information security governance (ISG) implementation among major Ghanaian industry sectors. The intent is to benchmark inter-industry sector ISG implementation and to identify areas that may require improvement.

Design/methodology/approach
– Random sampling strategy was used, and data were collected via Web survey. The data analysis utilized a one-way analysis of variance to determine the differences in means of the levels of implementation of ISG focus areas among five main industry sectors.

Findings
– The results showed that, as a whole, all the industry sectors have only partially implemented ISG. In particular, there existed statistical significant differences in ISG implementation among the industry sectors. Ranking ISG implementation, Financial Institutions were close to completion, Utility Companies, Others (Information Technology, Oil and Gas, Manufacturing) and Public Services had PI ISG and health care and educational institutions were at the planning stages. The result also revealed that all the industry sectors made marginal effort trying to align information security to business strategy, and performance measurement remained the least implemented focus area.

Originality/value
– Organizational leaders could use these findings to benchmark industry sectors’ ISG implementation, which could lead to competitiveness. Again, international enterprises that do businesses with these industry sectors would better understand the level of involvement of the top executives in governing information security toward the protection of valuable information assets.
Understanding the roles of loss-premium comparisons and insurance coverage in customer acceptance of insurance claim frauds
Authors: Tseng Lu-Ming , Kang Yue-Min , Chung Chi-Erh 
Published: July 2014

Purpose
– The purpose of this paper is to examine the impacts of loss-premium comparisons (loss-premium comparison refers to the amount of an actual loss compared to the premium level) and insurance coverage on customer acceptance of insurance claim frauds, based on Adams’ equity theory. Customer perceptions of insurance frauds have been studied in recent years.

Design/methodology/approach
– A questionnaire was used as an instrument in the research. The hypotheses were tested using a 3 loss-premium comparisons (the actual loss amount was lower than, or equal to or higher than the annual premium) × 2 insurance coverage (the loss is covered or not covered by the insurance policy) experimental design in a claim application context.

Findings
– The results showed that loss-premium comparisons and insurance coverage significantly affect the final claim amounts. According to the results, age and education may relate to customer acceptance of insurance claim frauds.

Originality/value
– This study proposed a first empirical investigation into the relationship between loss-premium comparisons and customer ethical decision making in the customer frauds. Insurance coverage is also specifically considered in the study.
