The Impact of Service Scripts on Customer Citizenship Behavior and the Moderating Role of Employee Customer Orientation
Authors: Nguyen Helena , Groth Markus , Walsh Gianfranco , Hennig‐Thurau Thorsten 
Published: October 2014

ABSTRACTService scripts are behavioral and verbal prescriptions used in many organizations as a way of standardizing employees’ behaviors during their interactions with customers. Yet, they have rarely been studied empirically. There are mixed suggestions in the literature about the beneficial vs. detrimental effects of service scripts. Based on social exchange and citizenship behavior theories, this study investigates whether the relationship between service scripts and an important customer outcome, customer citizenship behavior (CCB), depends on employees’ level of customer orientation. Based on 285 matched dyads of employees and customers from a variety of service organizations, the study found that when service scripts are performed by employees with low customer orientation, service scripts have more detrimental effects on CCB in terms of reducing the propensity among customers to provide unsolicited feedback and their intentions to return to the service firm. There was also support for the mediating role of perceived service quality in accounting for these contingent relationships. These findings contribute to the literature on managing employee behavior and CCB.
Viewing Responsible Consumption as a Personal Project
Authors: Valor Carmen , Carrero Isabel 
Published: October 2014

ABSTRACTPrevious research on “responsible consumption” (RC) has focused on the inconsistencies of responsible consumers and has used the term “gap” to refer to these inconsistencies. Observable difficulties, such as a lack of available responsible products and their higher associated costs, have been given as explanations for this gap. A much more complex explanation emerges when RC is seen holistically, a long‐term perspective is adopted, when consumers are studied in their daily life, and consumption is seen as a social activity. The argument developed in this paper draws fundamentally on psychology, in particular on the literature on personal projects. By using an inductive methodology (grounded theory), a case is made for treating responsible consumption as one of many personal projects that an individual may undertake. Since consumers have a project network and projects are not always aligned with one another, there is frequently a clash between projects. This clash can be interpersonal (with other projects of the same individual) or intrapersonal (with the projects, beliefs, norms of his/her significant others). The main contribution of this paper is that it puts forward a holistic, dynamic, and socially embedded view of RC which leads to questioning the notion of “gap.”
“My Avatar and Her Beloved Possession”: Characteristics of Attachment to Virtual Objects
Authors: Nagy Peter , Koles Bernadett 
Published: October 2014

ABSTRACTGiven the increasing emphasis on online consumption in our digital era, the current study aimed to explore the avatar–self relationship in association with the concept of product attachment. Through constructing their own avatars and selecting certain virtual possessions for them, participants in the sample were able to represent different elements of their identities to be manifested in their embodied virtual presence. Certain attributes and emotions characterizing both the real as well as the virtual existence of participants appeared to exert important influences. Additional gender differences emerged, in that males were more likely to represent their possible and hidden self‐aspects, and focus on the functional meaning of virtual products, while females were more likely to reveal their ideal selves, and attach symbolic meaning to their virtual possessions. For female participants, the role of experimentation emerged as an important construct, with their avatars often reflecting upon their ambivalence toward perceived social norms and societal expectations. Implications for scholars and practitioners are discussed.
Stiff Limb Syndrome Mimicking Corticobasal Syndrome
Authors: Balint Bettina , Mahant Neil , Meinck Hans‐Michael , Fung Victor 
Published: October 2014

AbstractStiff limb syndrome (SLS) is a focal variant of the spectrum of stiff person syndrome. Its presentation with stiffness, limb posturing, and freezing‐of‐gait (FOG)‐like episodes, together with the relative rareness of the disorder, make it conceivable that SLS might be misdiagnosed as atypical parkinsonism, in particular, corticobasal syndrome (CBS). To illustrate this, we present two cases of established SLS resembling CBS and discuss the distinguishing features that may alert the clinician to the correct diagnosis, with its obvious therapeutic and prognostic implications.
Method for B0 off‐resonance mapping by non‐iterative correction of phase‐errors (B0‐NICE)
Authors: Liu Junmin , Drangova Maria 
Published: October 2014

PurposeTo develop and evaluate a multiecho phase‐unwrapping‐based B0 mapping method.MethodsThe proposed method estimates a B0 map by Non‐Iterative Correction of phase‐Errors (B0‐NICE). The B0‐NICE method generates an initial B0 map from a “pseudo in‐phase” data set by introducing a bias frequency shift to the multipeak fat model, followed by correcting the phase errors using both phase and magnitude information. The performance of the B0‐NICE method was evaluated with all data cases from the 2012 ISMRM Challenge.ResultsThe B0 field estimates from B0‐NICE were compared with those generated by GlObally Optimal Surface Estimation (GOOSE). In the presence of large B0 inhomogeneity, the B0‐NICE method was able to generate more realistic B0 maps from multiecho data, compared with GOOSE. Accurate estimation of fat‐fraction (FF) map was also achieved using the proposed algorithm.ConclusionThe primary finding of the present study is that accurate FF and B0 maps are achievable if magnitude data is processed independently and used to correct phase errors existing in B0 maps generated by phase unwrapping. The B0‐NICE software is freely available to the scientific community. Magn Reson Med 74:1177–1188, 2015. © 2014 Wiley Periodicals, Inc.
Maternal–Infant Interaction and Autonomic Function in Healthy Infants and Infants With Transposition of the Great Arteries
Authors: Harrison Tondi M. , Ferree Allison 
Published: October 2014

AbstractThe quality of maternal–infant interaction is a critical factor in the development of infants' autonomic function and social engagement skills. In this secondary data analysis, relationships among infant and maternal affect and behavior and quality of dyadic interaction, as measured by the Parent–Child Early Relational Assessment, and infant autonomic function, as measured by heart rate variability, were examined during feeding at 2 weeks and 2 months of age in 16 healthy infants and in 15 infants with transposition of the great arteries (TGA). Contrary to previous research, at 2 weeks infant age, mothers of infants with TGA had significantly higher scores in affect and behavior than did mothers of healthy infants. The affect and behavior and quality of dyadic interaction of infants with TGA also did not differ from that of healthy infants. Although infants' social engagement skills did not differ by health condition (TGA or healthy), these skills did differ by parasympathetic nervous system function: infants better able to suppress vagal activity with challenge had more positive and less dysregulated affect and behavior, regardless of health status. These findings suggest that maternal–infant interactions for some cardiac disease subgroups may not differ from healthy dyads. Additional research is required to identify both healthy and ill infants with delayed autonomic maturation and to develop and test interventions to enhance critical interactive functions. © 2014 Wiley Periodicals, Inc.

AbstractInflammation is associated with several diseases of the prostate including benign enlargement and cancer, but a causal relationship has not been established. Our objective was to characterize the prostate inflammatory microenvironment after infection with a human prostate‐derived bacterial strain and to determine the effect of inflammation on prostate cancer progression. To this end, we mimicked typical human prostate infection with retrograde urethral instillation of CP1, a human prostatic isolate of Escherichia coli. CP1 bacteria were tropic for the accessory sex glands and induced acute inflammation in the prostate and seminal vesicles, with chronic inflammation lasting at least 1 year. Compared to controls, infection induced both acute and chronic inflammation with epithelial hyperplasia, stromal hyperplasia, and inflammatory cell infiltrates. In areas of inflammation, epithelial proliferation and hyperplasia often persist, despite decreased expression of androgen receptor (AR). Inflammatory cells in the prostates of CP1‐infected mice were characterized at 8 weeks post‐infection by flow cytometry, which showed an increase in macrophages and lymphocytes, particularly Th17 cells. Inflammation was additionally assessed in the context of carcinogenesis. Multiplex cytokine profiles of inflamed prostates showed that distinct inflammatory cytokines were expressed during prostate inflammation and cancer, with a subset of cytokines synergistically increased during concurrent inflammation and cancer. Furthermore, CP1 infection in the Hi‐Myc mouse model of prostate cancer accelerated the development of invasive prostate adenocarcinoma, with 70% more mice developing cancer by 4.5 months of age. This study provides direct evidence that prostate inflammation accelerates prostate cancer progression and gives insight into the microenvironment changes induced by inflammation that may accelerate tumour initiation or progression.

Published: October 2014

ABSTRACTA new class of π‐conjugated, skewed H‐shaped oligomers, consisting of biphenyl, phenylene vinylene, and phenylene ethynylene units as the rigid segment, were synthesized via Sonogashira coupling and Wittig reactions. The coil segments of these molecules were composed of poly(ethylene oxide) (PEO) or PEO with lateral methyl groups between the rod and coil segment, respectively. The experimental results revealed that the lateral methyl groups attached to the surface of the rod and coil segments dramatically influenced the self‐assembling behavior of the molecules in the crystalline phase. H‐shaped rod–coil molecules containing a lateral methyl group at the surface of the rod and PEO coil segments self‐assemble into a two‐dimensional columnar or a three‐dimensional body‐centered tetragonal nanostructures in the crystalline phase, whereas molecules lacking a lateral methyl group based on the PEO coil chain self‐organize into lamellar or hexagonal perforated lamellar nanostructures. © 2014 Wiley Periodicals, Inc.

AbstractInternal migration within Asian countries and international migration to, within, and out of Asia have been on the rise throughout the past decades. As types and pathways of migration, migrants' sociocultural and socioeconomic backgrounds, and their transnational and translocal trajectories become increasingly diverse, a majority of them move to cities. Diverging power geometries and relations are constantly negotiated and (re)produced in the socio‐spatial dialectic of the city. Through their individual and collective agency, assets, and knowledge, mobile subjects have become important agents in the (re)production of spaces in cities, whereas the socio‐political and physical conditions of spaces frame their livelihoods, opportunities, and agency. Research on migrants' agency has intensified recently, but the specific modes through which agency operates in the socio‐spatial dialectic still need to be conceptualised. We develop a framework that outlines different modes through which agents and space interact. The framework is exemplified through papers on case studies from Dhaka and the Pearl River Delta (PRD) that are part of this special issue. Dhaka and the PRD have been characterised by accelerated growth throughout the past decades, particularly due to the influx of rural‐to‐urban migrants, but they also receive an increasing number of international migrants. We conclude that through their diverse, multi‐sited, andtranslocal relations and activities stretching beyond the receiving cities in a context of constanttransformation, migrants' practices contribute to the emergence of a specific type of urban spaces that we delineate astransient urban spaces.

Migration, Informal Labour and (Trans) Local Productions of Urban Space – The Case of Dhaka's Street Food Vendors
Authors: Etzold Benjamin 
Published: October 2014

AbstractIn Bangladesh, Dhaka is migrants' most important destination and has itself been fundamentally transformed through migration. But there is ‘no place’ for many migrants in Dhaka. Poorer migrants live in slums and many encroach on public space to sustain their lives – the new urbanites are taking their ‘right to the city’. In doing so, they not only draw on local resources. Their production of the urban space often relates directly to their migration trajectory, their translocal networks, and their simultaneous situatedness at multiple places. Migrants connect ‘the rural’ and ‘the urban’ and constitute translocal spaces, which contribute to re‐making Dhaka from below.This paper integrates current debates on translocality, informal labour, and subaltern urbanism to address two key questions on transient urban spaces: How do migration trajectories and translocality structure the urban poor's lives? How do migrants make use of local networks and translocal social relations to find work and appropriate ‘their place’ in the city? Empirical research on street food vendors in Dhaka, almost all of whom are internal migrants, builds the basis for my argument. I show that ‘translocal social capital’ and home‐bound identities can be important resources to gain access to urban labour markets and to appropriate one's place in the city. The paper argues that the poor use translocality for their livelihoods and thereby continuously re‐shape the face of the megacity of Dhaka. Copyright © 2014 John Wiley & Sons, Ltd.
Observation of negative refraction in the graphene/ferrite composite
Authors: Oganisian Karen , Strek Wieslaw 
Published: October 2014

An observation of negative refraction in the naturally obtained composition of graphene and barium ferrite is reported. The capacitance and inductance measurements revealed the electric and magnetic resonances accompanied with the negative values of permittivity and permeability in the overlapped frequency range. According to the “left‐handed” media approach such a material is characterized by negative refraction. The derived values of the real part of refractive index are negative at the frequencies above 500 MHz.

Swarm‐based metaheuristics in automatic programming: a survey
Authors: Olmo Juan L. , Romero José R. , Ventura Sebastián 
Published: October 2014

On the one hand, swarm intelligence (SI) is an emerging field of artificial intelligence that takes inspiration in the collective and social behavior of different groups of simple agents. On the other hand, the automatic evolution of programs is an active research area that has attracted a lot of interest and has been mostly promoted by the genetic programming paradigm. The main objective is to find computer programs from a high‐level problem statement of what needs to be done, without needing to know the structure of the solution beforehand. This paper looks at the intersection between SI and automatic programming, providing a survey on the state‐of‐the‐art of the automatic programming algorithms that use an SI metaheuristic as the search technique. The expression of swarm programming (SP) has been coined to cover swarm‐based automatic programming proposals, since they have been published to date in a disorganized manner. Open issues for future research are listed. Although it is a very recent area, we hope that this work will stimulate the interest of the research community in the development of new SP metaheuristics, algorithms, and applications.

Published: October 2014

AbstractThe reaction of alkali sulfates and boron oxide in oleum yielded the complexes A[B(S2O7)2] (A = Li, Na, K, NH4). This way we obtained the first ammonium‐containing borosulfate and we determined the crystal structure. NH4[B(S2O7)2] [Cc, Z = 8, a = 11.4403(2), b = 14.9439(2) c = 13.8693(2) Å] crystallizes isotyp to K[B(S2O7)2]. Thermal decomposition or treatment in vacuo resulted in compounds with composition A[B(SO4)2]. One‐dimensional chain structures are obtained for A = Na, K, NH4. NH4[B(SO4)2] [P4/ncc, Z = 4, a = 9.1980(1), c = 7.4258(1) Å] and K[B(SO4)2] [P4/ncc, Z = 4, a = 8.9739(3), c = 7.4114(3) Å] are isotyp with H3O[B(SO4)2]. The chains of edge‐sharing “BS4 super tetrahedra” have $\bar{4}$ symmetry. In Na[B(SO4)2] [P2/c, Z = 2, a = 5.434(5), b = 7.570(7) c = 7.766(8) Å, β = 108.56(3)°] the chain is twisted. Li5[B(SO4)4] [P21/c, Z = 4, a = 8.0191(1), b = 10.1211(1) c = 15.0401(2) Å, β = 104.033(1)°] contains isolated pentameric unit and represents a new structure type. Li5[B(SO4)4] was obtained from Li[B(S2O7)2] with additional Li2SO4/SO3. Vibrational spectra of A[B(S2O7)2] (A = Na, K, NH4) are presented and force constants calculated. In all structures BO4 and SO4 tetrahedra are connected by common apices forming BS4 super tetrahedra.

AbstractWe report the high‐pressure synthesis and the structure of aluminum hexathiohypodiphosphate, Al4(P2S6)3, along with the redetermination of the structures of two modifications of AlPS4. Al4(P2S6)3 crystallizes in the monoclinic space group C2 with a = 17.584(3), b = 10.156(2), c = 6.698(1) Å, β = 106.93(1)° in a superstructure of the layered FePS3 structure type with tripled a axis. Hereby, Al3+ occupies 2/3 of the Fe2+ sites in an ordered fashion. The structure model obtained from single‐crystal X‐ray diffraction was corroborated by TEM‐PED. The low‐temperature modification of AlPS4 with platelet‐like morphology shows tetragonal symmetry [space group P$\bar{4}$2c, a = b = 5.6572(9), c = 9.220(2) Å]. The orthorhombic high‐temperature modification with fibrous needle‐like morphology of AlPS4 is isotpyic with BPS4 [space group I222, a = 5.660(2), b = 5.759(2), c = 9.189(2) Å].
Preparation, Properties, and Structures of Pentanuclear [{Ni2L}2(μ‐csalen)M]2+ Complexes (L = Macrocyclic N6S2 ­Donor Ligand)
Authors: Golecki Matthias , Kersting Berthold 
Published: October 2014

AbstractThe dinuclear nickel complex [Ni2L(μ‐Cl)]+ (1), where L2– is a 24‐membered macrocyclic N6S2 ligand, reacts readily with 3‐formyl‐4‐hydroxy‐benzoic acid (Hfhba) to form the carboxylato‐bridged complex [Ni2L(μ‐fhba)]+ (2). Complex 2 undergoes a condensation reaction with ethylene diamine to produce a tetranuclear complex [{Ni2L}2(μ‐H2csalen)]2+ (3), in which two dinuclear {Ni2L} units are bridged via the deprotonated carboxylate functions of the csalen ligand N,N′‐bis(4‐carboxysalicylidene)‐1, 2‐diaminoethane. The same compound can also be prepared directly from 1 and H2csalen. The complexation of 3 with NiCl2·6H2O, Cu(OAc)2·H2O or Pd(OAc)2 provides pentanuclear complexes of the type [{Ni2L}2(μ‐csalen)M]2+ [M = Ni (4a), Cu (4b), Pd (4c)]. All complexes were isolated as perchlorate salts and studied by ESI‐MS, infrared, and UV/Vis spectroscopy. The tetraphenylborate salt of 4c was also characterized by X‐ray crystallography. The [(csalen)M] complex units act in all cases as quadridentate bridging ligands linking two bioctahedral {Ni2L} units via μ‐1, 3‐bridging carboxylate functions. The palladium complex 4c was found to catalyze Heck‐coupling reactions of various iodobenzenes with methyl acrylate and styrene.
Interaction of TNT and Aluminum – A DFT Treatment
Authors: Türker Lemi 
Published: October 2014

AbstractWithin the constraints of density functional theory [UB3LYP/6‐31G(d, p) and UB3LYP/6‐31++G(d, p)], TNT/Al and TNT/2Al composites are investigated, considering various multiplicity states. Depending on the localization of aluminum atoms in space and multiplicity of the composite systems, the structure of TNT undergoes various degrees of perturbations. It was shown that the presence of aluminum atoms affects the bond lengths, electron population as well as the HOMO–LUMO energy gap of TNT. All these are thought to affect ballistic properties of the explosive molecule.
