Does Brand Licensing Increase a Licensor's Shareholder Value?
Authors: Robinson Adina Bărbulescu , Tuli Kapil R. , Kohli Ajay K. 
Published: August 2014

This study examines 171 brand licensing announcements and subsequent changes in the licensor firms' shareholder values using the event study method. We find that although brand licensing announcements lead to positive abnormal returns on average, nearly 44% of the announcements in our sample are followed by negative abnormal returns. We argue that investors react more favorably to a brand licensing announcement when they believe (i) the brand has greater ability to stimulate licensee product sales (and thus generate higher royalties for the licensor) and (ii) the licensor firm has greater ability to limit licensee opportunism (and thus limit brand dilution and its adverse effect on sales of other products marketed under the brand name). In line with our hypotheses related to a brand's ability to stimulate licensee product sales, the study's findings suggest that investors react more favorably to announcements involving brands with greater brand fit and greater brand breadth. However, investors appear to react less favorably to announcements involving brands with higher advertising investments. In line with our hypotheses related to a licensor firm's ability to limit licensee opportunism, the study's findings suggest that investors react more favorably to announcements involving larger licensors; however, investors' reactions do not appear to be influenced by licensor firms' licensing experience.

Published: August 2014

We describe the impact of a targeted performance improvement programme and the associated performance improvement interventions, on mortality rates, error rates and process of care for haemodynamically unstable patients with pelvic fractures. Clinical care and performance improvement data for 185 adult patients with exsanguinating pelvic trauma presenting to a United Kingdom Major Trauma Centre between January 2007 and January 2011 were analysed with univariate and multivariate regression and compared with National data. In total 62 patients (34%) died from their injuries and opportunities for improved care were identified in one third of deaths. Three major interventions were introduced during the study period in response to the findings. These were a massive haemorrhage protocol, a decision-making algorithm and employment of specialist pelvic orthopaedic surgeons. Interventions which improved performance were associated with an annual reduction in mortality (odds ratio 0.64 (95% confidence interval (CI) 0.44 to 0.93), p = 0.02), a reduction in error rates (p = 0.024) and significant improvements in the targeted processes of care. Exsanguinating patients with pelvic trauma are complex to manage and are associated with high mortality rates; implementation of a targeted performance improvement programme achieved sustained improvements in mortality, error rates and trauma care in this group of severely injured patients.

A systematic review and meta-analysis of patient-specific instrumentation for improving alignment of the components in total knee replacement
Authors: Thienpont E. , Schwab P. E. , Fennema P. 
Published: August 2014

We conducted a meta-analysis, including randomised controlled trials (RCTs) and cohort studies, to examine the effect of patient-specific instruments (PSI) on radiological outcomes after total knee replacement (TKR) including: mechanical axis alignment and malalignment of the femoral and tibial components in the coronal, sagittal and axial planes, at a threshold of > 3º from neutral. Relative risks (RR) for malalignment were determined for all studies and for RCTs and cohort studies separately. Of 325 studies initially identified, 16 met the eligibility criteria, including eight RCTs and eight cohort studies. There was no significant difference in the likelihood of mechanical axis malalignment with PSI versus conventional TKR across all studies (RR = 0.84, p = 0.304), in the RCTs (RR = 1.14, p = 0.445) or in the cohort studies (RR = 0.70, p = 0.289). The results for the alignment of the tibial component were significantly worse using PSI TKR than conventional TKR in the coronal and sagittal planes (RR = 1.75, p = 0.028; and RR = 1.34, p = 0.019, respectively, on pooled analysis). PSI TKR showed a significant advantage over conventional TKR for alignment of the femoral component in the coronal plane (RR = 0.65, p = 0.028 on pooled analysis), but not in the sagittal plane (RR = 1.12, p = 0.437). Axial alignment of the tibial (p = 0.460) and femoral components (p = 0.127) was not significantly different. We conclude that PSI does not improve the accuracy of alignment of the components in TKR compared with conventional instrumentation. Cite this article: Bone Joint J 2014; 96-B:1052–61.
A Method To Evaluate Lost-Circulation Materials—Investigation of Effective Wellbore-Strengthening Applications
Authors: Savari Sharath , Whitfill Donald L. , Jamison Dale E. , Kumar Arunesh 
Published: August 2014

Summary
With increased drilling activity in deeper, harsher, and more-complex environments, controlling nonproductive time during drilling is critical to lowering the cost of well construction. Lost circulation (LC), one of the main contributors to nonproductive time, is a widely discussed topic drawing industry attention, as is evident from recent publications and forums/workshops on the topic. The literature on LC reveals several means of mitigation, ranging from the simple use of lost-circulation materials (LCMs) to the use of gunk/chemical sealants and methods for altering near-wellbore stresses (stress caging or wellbore strengthening). There is a subtle difference between LC and wellbore strengthening, and any research should help facilitate a better understanding of the two.
Presented previously (Kumar et al. 2010; Savari et al. 2012) were novel insights into LCMs for wellbore-strengthening applications. Continuing the research effort, this paper discusses another approach for designing LCMs to withstand higher wellbore pressures within a fracture. A property of plug-breaking pressure (PBP) was determined for different LCM combinations by use of a permeability-plugging apparatus (PPA) with tapered slots. LCM combinations with differing mechanical properties behaved differently compared with PBP data. Particles, such as ground marble, alone were not able to plug the tapered slot, and hence the PBP was zero. By use of the previous work described by Savari et al. (2012), the addition of resilient graphitic carbon (RCG) helped with plugging the tapered slot, with a PBP of approximately 900 psi. Adding fibers to the LCM combination was also evaluated. Plugging did not improve when fibers were added only to one other type of particulate LCM. But, the combination of ground marble, RGC, and specific fibers was found to provide the most-efficient plugging, with the highest PBP of approximately 2,100 psi.
This work confirms that all LCMs are not equal and that the LCM type plays a role in terms of both plugging and “toughness” to better withstand displacement pressures. It also validates that, most of the time, combinations of LCMs work more effectively compared with the use of only one type. The novel PBP data on different LCM combinations can provide a qualitative comparison of their ability to withstand displacement and/or failure pressures when designing LCM combinations in wellbore-strengthening applications.
A Pseudobubblepoint Model and Its Simulation for Foamy Oil in Porous Media

Published: August 2014

Summary
This is the second paper of a series in which we study heavy oil in porous media. The first paper dealt with an experimental study (Wang et al. 2008), whereas a mathematical and simulation study is presented here. The research program stems from the need to predict the field performance of a class of heavy-foamy-oil reservoirs. These reservoirs show a better-than-expected primary performance: lower production gas/oil ratios (GORs), higher-than-expected production rates, and higher oil recovery. A mechanism used to account for the observed performance is that the liberated solution gas is entrained in the oil when the reservoir pressure falls below the thermodynamic equilibrium bubblepoint pressure. The presence of entrained gas increases the effective compressibility of the oil phase and prevents gas from becoming a free phase. Hence, the foamy oil behaves as if it had a pseudobubblepoint pressure below the usual equilibrium bubblepoint pressure. This paper describes a pseudobubblepoint model and a methodology that can be used to compute foamy-oil fluid properties from conventional laboratory pressure/volume/temperature (PVT) data. The techniques developed are then used to study foamy oil in the Orinoco belt, Venezuela. The present mathematical model is validated by comparing numerical and experimental results.
Product Market Power and Tax Avoidance: Market Leaders, Mimicking Strategies, and Stock Returns
Authors: Kubick Thomas R. , Lynch Daniel P. , Mayberry Michael A. , Omer Thomas C. 
Published: August 2014

ABSTRACT
Product market power provides firms with comparative advantages through more persistent profitability and insulation from competitive threats. These advantages likely provide firms with the ability to engage in greater tax avoidance. We present evidence consistent with this hypothesis. We also show that firms mimic the tax outcomes of their product market leaders. Among firms with greater product market power and comparatively high cash tax avoidance, we find stock prices to be less informative and that investors require additional compensation for the risks associated with comparatively high cash tax avoidance. Our results survive numerous robustness tests. Overall, our results suggest that industry dynamics, particularly related to a firm's competitive position, play a meaningful role in corporate tax policy.
The Distinction Between Randomized Clinical Trials (RCTs) and Preliminary Feasibility and Pilot Studies: What They Are and Are Not
Authors: Abbott J. Haxby 
Published: August 2014

Feasibility and pilot studies play an important role in the preliminary planning of a proposed full-size randomized clinical trial (RCT). In essence, feasibility studies are used to help develop trial interventions or outcome measures, whereas pilot studies replicate, in miniature, a planned full-size RCT. However, the terms used for these preliminary studies are sometimes considered synonymous, and in practice may overlap considerably or be combined. The important issue is not the distinction between these: the important distinction is between such preliminary studies and a proper RCT.

Authors: Biasin Louis , Sage Michael D. , Brunton Karen , Fraser Julia , Howe Jo-Anne , Bayley Mark , Brooks Dina , McIlroy William E. , Mansfield Avril , Inness Elizabeth L. 
Published: August 2014

Background
Aerobic activity positively affects patients recovering from stroke and is part of best practice guidelines, yet this evidence has not been translated to routine practice.

Objective
The objective of this study was to evaluate the feasibility of a model of care that integrated aerobic training in an inpatient rehabilitation setting for patients in the subacute stage of stroke recovery. Key elements of the program were personalized training prescription based on submaximal test results and supervision within a group setting.

Design
This was a prospective cohort study.

Methods
Participants (N=78) completed submaximal exercise testing prior to enrollment, and the test results were used by their treating physical therapists for exercise prescription. Feasibility was evaluated using enrollment, class attendance, adherence to prescription, and participant perceptions.

Results
Overall, 31 patients (40%) were referred to and completed the exercise program. Cardiac comorbidities were the main reason for nonreferral to the fitness group. Program attendance was 77%; scheduling conflicts were the primary barrier to participation. The majority of participants (63%) achieved 20 minutes of continuous exercise by the end of the program. No adverse events were reported, all participants felt they benefited from the program, and 80% of the participants expressed interest in continuing to exercise regularly after discharge.

Limitations
Cardiac comorbidities prevented enrollment in the program for 27% of the admitted patients, and strategies for inclusion in exercise programs in this population should be explored.

Conclusions
This individualized exercise program within a group delivery model was feasible; however, ensuring adequate aerobic targets were met was a challenge, and future work should focus on how best to include individuals with cardiac comorbidities.
Le Bug, vers la gestion commune d'une rivière frontière entre un pays de l'Union européenne, la Pologne, et ses voisins, l'Ukraine et la Biélorussie
Authors: Gaunard-Anderson Marie-France 
Published: August 2014

The Western Bug is one of the major border rivers in Central and Eastern Europe. It is the border between Poland and Ukraine and between Poland and Belarus, but at the same time it is one of the European Union's external borders. Despite this particular position and a certain number of political, legal, economic and human barriers, cross-border cooperation is improving in order to preserve water resources and promote better management. This article illustrates the main steps that lead to this cooperation and seeks to analyze whether it will be possible to set up common management of the Bug river basin. Spanish

Published: August 2014

An intramedullary spinal cord abscess, which is usually associated with discitis, is an uncommon but potentially important complication of vertebral osteomyelitis. The authors describe a rare case of an intramedullary conus medullaris abscess and lumbar osteomyelitis sparing the intervertebral discs and without discitis. The patient also developed a granuloma in the cauda equina during treatment. Diffusion-weighted MRI was useful for differentiating the granulomatous lesion from the relapse of infection.
A 65-year-old immunocompetent man with moderately controlled diabetes presented with progressive lowerextremity numbness and weakness with urinary dysfunction. He had progressive paraparesis, bilateral leg paresthesia, and sphincter compromise. Magnetic resonance imaging revealed an intramedullary ring-enhanced lesion, which was hyperintense on diffusion-weighted images. The lesion, an intramedullary spinal cord abscess, was surgically drained. During antibiotic treatment, serial MRI showed an enlarging enhanced lesion in the cauda equina, and a recurrent infection was suspected. A second-look surgery confirmed the formation of a granuloma and the absence of a relapse of the abscess. Although the enhanced lesion increased in size, its intensity on diffusion-weighted images remained unchanged. After 3 months of antibiotic treatment, all enhanced lesions were diminished.
An intramedullary spinal cord abscess is a rare but important complication of vertebral osteomyelitis, and it requires immediate treatment. Diffusion-weighted MRI was useful for the initial diagnosis as well as for monitoring treatment efficacy.
Decompression and nonfusion dynamic stabilization for spinal stenosis with degenerative lumbar scoliosis
Authors: Lee Soo Eon , Jahng Tae-Ahn , Kim Hyun-Jib 
Published: August 2014

Object
Spinal stenosis with degenerative lumbar scoliosis (DLS) mostly occurs in the elderly population (typically > 65 years old), causing pain in the legs and back, claudication, and spinal deformity. The surgical strategy for DLS is controversial concerning the surgical approach, fusion area, decompression area, correction methods, and ideal angle of curve correction. A nonfusion stabilization system with motion preservation has been recently used for degenerative spinal diseases with favorable outcomes. This study attempted to analyze surgical outcomes after decompression and nonfusion stabilization for spinal stenosis with a mild to moderate degree of DLS.

Methods
Twenty-eight patients (21 women and 7 men, with a mean age of 65.3 years) with spinal stenosis and DLS who underwent decompressive surgery and nonfusion stabilization with the Dynesys system were included in this study. Medical records and radiological studies were reviewed to access clinical and radiological outcomes and surgery-related complications.

Results
Fifty-nine segments were decompressed and stabilized without fusion in 28 patients, consisting of 1 segmental stabilization in 8 patients (28.6%, L4–5), 2 segmental stabilizations in 11 patients (39.3%, L3–5), 3 segmental stabilizations in 7 patients (25.0%, L2–5 in 6 patients, L3–S1 in 1 patient), and 4 segmental stabilizations in 2 patients (7.1%, L2–S1 in 1 patient, L1–5 in 1 patient). The mean follow-up period was 30.7 months. Radiologically, the mean lumbar scoliotic angle was 13.7° before surgery, 5.1° at 3 months postoperatively, 3.8° at 12 months postoperatively, 4.2° at 24 months postoperatively, and 3.9° at the last follow-up, which was statistically significant (p < 0.05). Lumbar lordosis and range of motion were preserved. The score on the visual analog scale for leg and back pain significantly decreased, and the Oswestry Disability Index significantly improved after surgery. There were no newly developed neurological deficits or aggravation of neurological symptoms. A radiolucent line around the pedicle screw was observed in 4 patients (14.2%) with 5 screws (2.8%).

Conclusions
Adding nonfusion stabilization after decompressive surgery resulted in a safe and effective procedure for elderly patients with lumbar stenosis with a mild to moderate scoliosis angle (< 30°). Statistically significant improvement of the clinical outcome was obtained at the last follow-up evaluation with no progression of the degenerative scoliosis.

Authors: Befeler Adam Ross , Daniels David J. , Helms Susan A. , Klimo Paul , Boop Frederick 
Published: August 2014

Object
Current data indicate the rate of head injuries in children caused by falling televisions is increasing. The authors describe these injuries and the cost incurred by them.

Methods
In a single-institution retrospective review, all children treated for a television-related injury at LeBonheur Children's Hospital, a Level I pediatric trauma center, between 2009 and 2013 were identified through the institution's trauma registry. The type, mechanism, and severity of cranial injuries, surgical interventions, outcome, and costs were examined.

Results
Twenty-six patients were treated for a television-related injury during the study period. Most injuries (22 cases, 85%) occurred in children aged 2–4 years (mean age 3.3 years), and 19 (73%) of the 26 patients were male. Head injuries occurred in 20 patients (77%); these injuries ranged from concussion to skull fractures and subdural, subarachnoid, and intraparenchymal hemorrhages. The average Glasgow Coma Scale score on admission was 12 (range 7–15), and 3 patients (12%) had neurological deficits. Surgical intervention was required in 5 cases (19%). The majority of patients made a full recovery. There were no deaths. The total cost for television-related injuries was $1.4 million, with an average cost of $53,893 per accident.

Conclusions
A high occurrence of head injuries was seen following television-related accidents in young children. This injury is ideal for a public education campaign targeting parents, health care workers, and television manufacturers.

Pressures on a multi-talented and beloved habitat (essay)
Animal and plant species in forest habitats are less threatened than those in other habitats. That is to be welcomed, but is no reason to rest on our laurels in self-satisfaction. This forest success story can be explained by the strict forest protection which exists in Switzerland. This model, which has been a success for over 100 years, is under greater and greater pressure. Some politicians and interest groups want to open the forest to residential development. For Pro Natura, a relaxation of forest protection on the Swiss Plateau is out of the question. The same harmful processes which have been responsible for the dramatic loss of agricultural land would be imported to the forest. The fact is that the increase in total Swiss forest area is entirely limited to the mountainous regions, and does not concern the Plateau. It is important, from an ecological and economic point of view, to use some parts of the forest in a sustainable way. However, it is also essential that other parts of the forest are allowed to follow their natural processes. Pro Natura recommends that 10% of the Swiss forest area should be forest nature reserves by 2030, and 8% special forest reserves. A fifth of the forest area can safely be devoted to conservation of biodiversity, while four fifths can be managed according to sustainability criteria.
