How marketing capabilities and current performance drive strategic intentions in international markets

Drawing from two strategic views of the firm—the capability-based view and performance-feedback theory—this study examines the role of both marketing capabilities and current market performance as potential influencers of two key aspects of the intended future competitive strategy of firms operating in international markets: efficiency and marketing differentiation. Hypotheses are developed and tested in a survey of a sample of British exporting manufacturers. The findings are supportive of a more prominent role of marketing capabilities over recent market performance on future strategic intentions in export markets. Additional analyses of firms with an already established market position reveal a clear effect of informational capability on marketing differentiation and of product development capability and current market performance on efficiency intentions. We also find that target international market competitive intensity is a direct driver of efficiency-related but not differentiation-related strategic intentions

Customer satisfaction and firm profits in monopolies: A study of utilities

There is a growing body of evidence that customer satisfaction is predictive of firms’ future financial performance. However, studies of this relationship have been limited to competitive markets, and monopolistic markets have been largely ignored. This study explores the large and important utilities market and exploits its unique regulatory requirements that generate detailed and reliable operating and accounting data to examine the overall relationship between customer satisfaction and utility profit and establish the causal mechanisms involved. Using data from U.S. public utility firms, the authors show that even when customer satisfaction does not affect future revenues, it does positively predict future profitability by reducing utility firm operating costs. More specifically, they find that higher satisfaction reduces the costs of utility firm distribution, customer service, and sales and general administration expenses. These findings and additional post hoc evidence are consistent with the notion that customer satisfaction (1) generates efficiency-enhancing benefits for utility firms by lowering the direct and employee engagement costs of dealing with dissatisfied customers and (2) fosters greater trust and cooperation from customers. This study has important implications for both managers and regulators and provides important new insights for market-based asset theory and regulatory economic theory

A formal specification can be used as an oracle in testing since one can determine whether an observed behaviour is allowed by the specification. This is an important feature of formal testing: behaviours of the system observed in testing are compared with the specification and ideally this comparison is automated. In this paper we study a formal testing framework to deal with systems that interact with their environment at physically distributed interfaces, called ports, and where choices between different possibilities are probabilistically quantified. Building on previous work, we introduce two families of schedulers to resolve nondeterministic choices among different actions of the system. The first type of schedulers, which we call global schedulers, resolves nondeterministic choices by representing the environment as a single global scheduler. The second type, which we call localised schedulers, models the environment as a set of schedulers with there being one scheduler for each port. We formally define the application of schedulers to systems and provide and study different implementation relations in this setting

Vibrio parahemolyticus septicaemia in a liver transplant patient: a case report

<p>Abstract</p> <p>Introduction</p> <p><it>Vibrio parahemolyticus </it>is the leading cause of vibrio-associated gastroenteritis in the United States of America, usually related to poor food handling; only rarely has it been reported to cause serious infections including sepsis and soft tissue infections. In contrast, <it>Vibrio vulnificus </it>is a well-known cause of septicaemia, especially in patients with cirrhosis. We present a patient with <it>V. parahemolyticus </it>sepsis who had an orthotic liver transplant in 2007 and was on immunosuppression for chronic rejection. Clinical suspicion driven by patient presentation, travel to Gulf of Mexico and soft tissue infection resulted in early diagnosis and institution of appropriate antibiotic therapy.</p> <p>Case presentation</p> <p>A 48 year old Latin American man with a history of chronic kidney disease, orthotic liver transplant in 2007 secondary to alcoholic end stage liver disease on immunosuppressants, and chronic rejection presented to the emergency department with fever, vomiting, abdominal pain, left lower extremity swelling and fluid filled blisters after a fishing trip in the Gulf of Mexico. Samples from the blister and blood grew <it>V. parahemolyticus</it>. The patient was successfully treated with ceftriaxone and ciprofloxacin.</p> <p>Conclusion</p> <p>Febrile patients with underlying liver disease and/or immunosuppression should be interviewed regarding recent travel to a coastal area and seafood ingestion.

People can prevent <it>Vibrio </it>sepsis and wound infections by proper cooking of seafood and avoiding exposure of open wounds to seawater or raw shellfish products.</p

Antimicrobial resistance profiles of bacteria associated with lower respiratory tract infections in cats and dogs in England.

BACKGROUND: Bacterial lower respiratory tract infections (bLRTIs) are common and potentially life threatening in cats and dogs. Antibiotic treatment is often initiated before the diagnosis of bLRTI; therefore improved knowledge of the aetiology and antibiotic susceptibility patterns of these infections is essential to inform empiric antibiotic choices. METHODS: A retrospective study of microbiological, cytological results and their drug susceptibilities from lower respiratory samples (n = 1989) processed in a UK commercial laboratory between 2002 and 2012 was carried out. RESULTS: Thirty-nine per cent of feline samples and 50% of canine samples were positive for bacterial growth with most yielding a single organism (72 % and 69%, respectively). Bordetella bronchiseptica (20.2% from dogs and 2.3% from cats), Pasteurella spp. (23.2%, 31.8%), E. coli (16.2%, 13.6%) and Pseudomonas spp. (11.1%, 11.4%) were most frequently isolated from cytologically positive samples which contained intracellular bacteria (10%, 14%). Amoxycillin-clavulanate, cephalothin, cefovecin, oxytetracycline and trimethoprim/sulfamethoxazole showed modest in vitro activity against E. coli from dogs (approximately 70% susceptibility). Pseudomonas spp. were resistant to enrofloxacin (50%), ticarcillin (25%) and marbofloxacin (13%) but showed lower or zero resistance to aminoglycosides (approximately 7%) and ciprofloxacin (0%). Multi drug resistance (acquired resistance to three or more antimicrobial drug classes) was particularly common among E. coli isolates, with 23% from feline samples and 43% from canine samples. CONCLUSION: Resistance to certain first-choice antibiotics was detected in bLRTIs highlighting the need for continued monitoring and sound evidence to inform decision-making in the management of these infections

Small Polarons in Transition Metal Oxides

The formation of polarons is a pervasive phenomenon in transition metal oxide compounds, with a strong impact on the physical properties and functionalities of the hosting materials. In its original formulation the polaron problem considers a single charge carrier in a polar crystal interacting with its surrounding lattice. Depending on the spatial extension of the polaron quasiparticle, originating from the coupling between the excess charge and the phonon field, one speaks of small or large polarons. This chapter discusses the modeling of small polarons in real materials, with a particular focus on the archetypal polaron material TiO2. After an introductory part, surveying the fundamental theoretical and experimental aspects of the physics of polarons, the chapter examines how to model small polarons using first principles schemes in order to predict, understand and interpret a variety of polaron properties in bulk phases and surfaces. Following the spirit of this handbook, different types of computational procedures and prescriptions are presented with specific instructions on the setup required to model polaron effects.Comment: 36 pages, 12 figure
