Surgical and Functional Outcomes in Patients Undergoing Total Knee Replacement With Patient-Specific Implants Compared With “Off-the-Shelf” Implants
Authors: Schwarzkopf Ran , Brodsky Merrick , Garcia Giancarlo A. , Gomoll Andreas H.
Published: July 2015

Background

Total knee arthroplasty (TKA) instrumentation and implant designs have been evolving, with one of the current innovations being patient-specific implants (PSIs).

Purpose

To evaluate whether there is a significant difference in surgical time, intraoperative blood loss, postoperative range of motion, and length of stay between PSI and conventional TKA.

Study Design

Cohort study; Level of evidence, 3.

Methods

A consecutive series of 621 TKA patients, 307 with PSIs and 314 with conventional implants, was reviewed. Differences in estimated blood loss, length of stay, range of motion, and surgical time/tourniquet time between the 2 cohorts were analyzed.

Results

Linear regression analysis demonstrated that PSI decreased estimated blood loss by 44.72 mL ( P < .01), decreased length of stay by 0.39 days ( P < .01), decreased postoperative range of motion by 3.90° ( P < .01), and had a negligible difference on surgical and tourniquet time.

Conclusion

The use of PSI is associated with decreased estimated blood loss, decreased length of stay, decreased range of motion, and no discernible difference in surgical or tourniquet time, all of which are unlikely to be clinically significant.

Authors: Huang Kai-Wen , Chieh Jen-Jie , Shi Jin-Cheng , Chiang Ming-Hsien
Published: July 2015

Biofunctionalized magnetic nanoparticles (BMNs) that provide unique advantages have been extensively used to develop immunoassay methods. However, these developed magnetic methods have been used only for specific immunoassays and not in studies of magnetic characteristics of materials. In this study, a common vibration sample magnetometer (VSM) was used for the measurement of the hysteresis loop for different carcinoembryonic antigens (CEA) concentrations (Φ
CEA) based on the synthesized BMNs with anti-CEA coating. Additionally, magnetic parameters such as magnetization (M), remanent magnetization (M
R), saturation magnetization (M
S), and normalized parameters (ΔM
R/M
R and ΔM
S/M
S) were studied. Here, ΔM
R and ΔM
s were defined as the difference between any ΦCEA and zero Φ
CEA. The parameters M, ΔM
R, and ΔM
S increased with Φ
CEA, and ΔM
S showed the largest increase. Magnetic clusters produced by the conjugation of the BMNs to CEAs showed a ΔM
S greater than that of BMNs. Furthermore, the relationship between ΔM
S/M
S and Φ
CEA could be described by a characteristic logistic function, which was appropriate for assaying the amount of CEAs. This analytic ΔM
S/M
S and the BMNs used in general magnetic immunoassays can be used for upgrading the functions of the VSM and for studying the magnetic characteristics of materials.

Published: July 2015

Background

It is important to evaluate dynamic changes in the joint space width of the ankle mortise in detail in order to better understand the pathology of foot and ankle disorders. However, there are few reports on changes in the joint space width of the foot and ankle assessed using 3D images. The purpose of this study was to determine the changes in the joint space width of the ankle (tibiotalar joint) in association with dorsiflexion and plantar flexion of the ankle joint in healthy feet.

Methods

Computed tomography (CT) images of 10 healthy feet were obtained in the neutral, plantarflexed and dorsiflexed positions of the ankle joint, from which 3D virtual models were fabricated of the tibia, fibula and talus. The 3D joint space width in these models was calculated using a custom made software program.

Results

The joint space width increased in the order of dorsiflexion, neutral position and plantar flexion. Regarding the amount of change in dorsiflexion and plantar flexion relative to the neutral position, there were no significant differences in the middle‐middle position. On the other hand, there were highly significant differences in the medial‐anterior, medial‐middle and medial‐posterior positions.

Conclusions

The joint space width of the ankle joint can be calculated accurately using 3D reconstruction images. Our findings should assist in clarifying pathology associated with movement of the ankle during the gait cycle based on changes in the joint space width in feet exhibiting disorders.
Introduction to this special section: Multiples from attenuation to imaging
Authors: Valenciano Alejandro , Chemingui Nizar
Published: July 2015

Multiples are events in the seismic record that have undergone more than one reflection. They cannot be imaged the same way as primary reflections, and consequently, they are often treated as “unwanted” events. Elimination of multiples is an integral part of the conventional imaging workflow. Significant effort is spent to attenuate these “unwanted” events, with mixed results in practice. In recent years, The Leading Edge has dedicated three special sections to multiple elimination (1999, 2005, and 2011). Those editions detail the evolution of theory and applications of multiple removal. On the other hand, imaging of multiple reflections has seen much less attention and has been limited to a few academic groups. This special section highlights several challenges in imaging with multiples. We review the handling of multiples from attenuation to imaging while we focus on new strategies that use multiples for enhanced imaging.
Multiple attenuation for shallow-water surveys: Notes on old challenges and new opportunities
Authors: Kostov Clement , de Melo Frederico Xavier , Raj Abhishek , Zarkhidze Alexander , Cooke Alex , Miers Glenn , Bacon John
Published: July 2015

Challenges are reviewed for multiple-attenuation workflows for shallow-water surveys, including the 3D surface-related multiple elimination (3D SRME) workflow as well as workflows that combine wavefield extrapolation and 3D SRME. A proposed workflow improves on 3D SRME results for shallow-water surveys while aiming to remove all surface-related multiples rather than just a subset from those multiples. The key step in this workflow is a 3D SRME prediction of free-surface multiples using two input data sets — the recorded data and another data set preprocessed to remove a subset of water-layer-related multiples. This approach reduces some of the amplitude distortions in the SRME model and leads to overall improvement in results. Properties of the proposed workflow are illustrated with data from two shallow-water surveys acquired in the North Sea with multimeasurement steamers. Processing of the densely sampled 3D shot gathers obtained by joint interpolation and deghosting using the multimeasurement data provides more accurate wavefield extrapolation, better constrained adaptive subtraction, and overall better multiple-attenuation results than processing data from each streamer independently.
Fast least-squares imaging with surface-related multiples: Application to a North Sea data set
Authors: Tu Ning , Herrmann Felix J.
Published: July 2015

In marine seismic acquisition, surface-related multiples constitute a significant portion of the acquired data. Typically, multiples are removed during early-stage data processing because they can lead to phantom reflectors during migration that might result in erroneous geologic interpretations. However, if properly dealt with, multiples can provide valuable extra information and can complement primaries in illuminating the subsurface. Reverse time migration has limitations in imaging multiples. A computationally efficient inversion procedure is proposed which jointly maps primaries and multiples to the true reflectors and estimates the source function on the fly. As a result, high-quality, mostly artifact-free broad-band images are obtained in which the imprint of the source function is partly removed at a computationally affordable expense compared with the combined costs of wave-equation-based surface-related multiple elimination and reverse time migration. All this is achieved by including the total downgoing wavefields as areal sources in least-squares migration in combination with curvelet-domain sparsity promotion. The proposed method is applied to a shallow-water marine data set from the North Sea which contains abundant short-period surface-related multiples, and the efficacy of the method is shown in eliminating coherent imaging artifacts associated with multiples. The benefits of joint imaging of primaries and multiples are demonstrated compared with imaging these signal components separately.

A clear example using multiples to enhance and improve imaging: Comparison of two imaging conditions relevant to this analysis
Authors: Ma Chao , Zou Yanglei
Published: July 2015

A one-dimensional (1D) prestack example is used to examine the use of multiples to obtain an approximate image of an unrecorded primary by using the space-and-time coincidence of upgoing and downgoing waves (Claerbout's imaging condition II). The result shows that the image of an unrecorded primary (extracted from a recorded multiple) can be used to augment and enhance subsurface imaging from recorded primaries when there is inadequate or insufficient acquisition of primaries. Imaging results are examined and analyzed from two different and classic imaging conditions: (1) the predicted coincident-source-and-receiver experiment at depth, at time equals zero (Claerbout's imaging condition III), and (2) Claerbout's imaging condition II. The result of that comparison represents the advantages of Claerbout's imaging condition III over Claerbout's imaging condition II in terms of image definitiveness and amplitude analysis. However, an adaptation that is motivated and inspired by Claerbout's imaging condition II can be used to improve imaging results by providing an approximate image of an unrecorded primary subevent of a recorded multiple. A clear example is provided of that method and the added value for imaging that it can represent.
Seam Update
Authors: Fehler Michael , Hoelting Cory , Liu Xiaoli , Wu Yafei
Published: July 2015

The SEAM Pore Pressure Prediction project is in the process of evaluating approaches for building a realistic model to be used for geophysical simulations to test predrill geophysical pore-pressure prediction methodologies. Although the project will focus mainly on seismic simulation, there is a possibility that other geophysical simulations will be conducted as well. With this in mind, our initial objective is to construct a model that is as realistic as possible and that has pore-pressure challenges similar to those encountered in state-of-the-art pore-pressure prediction efforts. Our initial focus is on evaluating how to modify the existing SEAM Phase I Deepwater model to meet our needs. (See the February 2010 and March 2011 issues of The Leading Edge for overviews of that model.)
Winning Formula, Man Management and the Inner Game: Commonalities of Success in the Ryder Cup and Super Bowl
Authors: Jenkins Simon
Published: July 2015

Using a conceptual framework based on the work of Mitch McCrimmon, who has highlighted false dichotomies of leadership and management, the Ryder Cup captaincy of Paul McGinley is examined in terms of man management, strategy and tactics, and the Inner Game. For purposes of comparison on these matters, reference is made to American Football coach Pete Carroll. This is a stimulus article aimed at making links between sport and business through invited commentaries. It is intended to provoke critical reflection on nebulous use of the term ‘leadership’ and that much ‘leadership development’ is concerned with matters such as selfawareness that are associated with ‘personal growth’. Attention is drawn to how McGinley's captaincy is couched in terms of a discourse of ‘management’.
Relationships between Organizational Justice and Coaches' Attitudinal Outcomes in Intercollegiate Sports
Authors: Kim Seungmo , Andrew Damon P.S.
Published: July 2015

The primary purpose of this study was to examine direct and indirect relationships between organizational justice and coaches' attitudinal outcomes (job satisfaction, affective organizational commitment toward organization and supervisor) through the mediating effects of social exchange variables. Head and assistant coaches (n = 260) at National Collegiate Athletic Association (NCAA) Divisions I, II, and III institutions in the United States participated in a survey. The results indicated full mediating effects of perceived organizational support (POS) between procedural justice and job satisfaction, but the results indicated no mediating effects of leader-member exchange (LMX) between procedural justice and job satisfaction. In addition, the results indicated full mediating effects of POS between procedural justice and affective commitment toward the athletic department as well as full mediating effects of LMX between procedural justice and affective commitment toward the athletic director. Practical applications of the findings are presented, and future research suggestions are proposed.
Effects of a Mastery Intervention Programme on the Motivational Climate and Achievement Goals in Sport Coaching: A Pilot Study
Authors: Hassan Mohamad Faithal Haji , Morgan Kevin
Published: July 2015

The task, authority, recognition, grouping, evaluation, and time structures (TARGET) have been identified as influential in determining a mastery motivational climate. To date, there is relatively little research on the use of TARGET based interventions in the sport setting. The purpose of this study was to examine the effects of a mastery intervention programme on sport coaches' TARGET behaviours and athlete's perceptions of the motivational climate and achievement goal orientations. Study participants included four coaches and 43 of their athletes from a young adult sport population, representing a range of different sports. A multi-methods approach was used in the examination of the link between coaching behaviours and athletes' psychosocial responses. Coaches' behaviours were assessed at three time points (pre, mid, and post-intervention), and athletes' self-perceptions were measured at two time points (pre and post-intervention). For coach observations, the percentage ‘mastery’, ‘ego’ and ‘neither’ TARGET behaviours were calculated for each of the three filmed coaching sessions. Wilcoxon tests were conducted in order to measure the differences between athletes' pre- and post-intervention perceptions of the motivational climate, and goal orientations. Results revealed increased mastery coaching behaviours and significant increases in athlete's perceptions of a mastery climate and task goal orientations and a significant decrease in ego perceptions of the climate and ego goal orientations. Given the adaptive motivational responses that are associated with a mastery climate and mastery goal orientations, this intervention has important implications for sport coaching.

Authors: Ko Myung-Sook , Doo Jung-Hee , Kim Jeong-Soo , Jeon Hye-Seon
Published: July 2015

Aim:

The aim of this study was to examine the effects of whole body vibration (WBV) training and conventional physical therapy on spatiotemporal gait parameters, functional mobility and activities of daily living (ADL) in children with cerebral palsy (CP).

Methods:

A pretest–posttest control group design was used. In this 3-week trial, 24 children with spastic CP were randomly selected to either continue their physical therapy or to receive WBV in addition to their physical therapy programme. Gait analyses, the Timed Up and Go (TUG) test and the Functional Independence Measure for Children (WeeFIM) were conducted before and after training.

Results:

For spatiotemporal gait parameters, this study found statistically significant differences in the WBV group's walking speed (p = 0.002), step length of the affected side (p = 0.021) and step width (p = 0.007) pre- and post-training. Between the two groups, there was a statistically significant difference in step width (F = 5.326, p = 0.031) and significant improvements in the WBV group's TUG scores (p = 0.039) compared with the control group. According to the results of WeeFIM, there were no significant differences between the two groups after training.

Conclusions:

Administration of WBV training to children with CP in conjunction with conventional physical therapy leads to improvements in functional mobility.

CHAETOMORPHA ANTENNIA EXTRACT AS A GREEN INHIBITOR FOR CORROSION OF BRASS IN 0.1 N PHOSPHORIC ACID SOLUTION
Authors: Kumar R , Chandrasekaran V
Published: July 2015

The effect of marine algae Chaetomorpha antennia extract on corrosion inhibition of brass in phosphoric acid was investigated by weight-loss method, potentiodynamic polarization and electrochemical impedance spectroscopy studies. The inhibition efficiency is found to increase with increasing concentration of extract and decreases with rise in temperature. The activation energy, thermodynamic parameters (free energy, enthalpy and entropy change) and kinetic parameters (rate constant and half-life) for inhibition process were calculated. These thermodynamic and kinetic parameters indicate a strong interaction between the inhibitor and the brass surface. The inhibition is assumed to occur via adsorption of inhibitor molecules on the brass surface, which obeys Temkin adsorption isotherm. The adsorption of inhibitor on the brass surface is exothermic, physical, and spontaneous, follows first order kinetics. The polarization measurements showed that the inhibitor behaves as a mixed type inhibitor and the higher inhibition surface coverage on the brass was predicted. Inhibition efficiency values were found to show good trend with weight-loss method, potentiodynamic polarization and electrochemical impedance spectroscopy studies. SEM was carried out to ascertain the inhibitive nature of the algal extract on the brass surface.
Determinants of take-up of welfare programmes: evidence from a conditional cash transfer in Kazakhstan
Authors: O'Brien Clare , Pellerano Luca
Published: July 2015

Households that are eligible for means-tested benefits do not always take them up, leading to potentially detrimental consequences associated with their unintended exclusion. This paper offers a framework for analysing non-take-up, covering households that are uninformed, misinformed, constrained or uninterested. Using quantitative evidence from an evaluation of a conditional cash transfer in Kazakhstan we compare the characteristics of enrolled and non-enrolled households and demonstrate that, before they receive transfers, households enrolled on that programme are typically less well-off than eligible households that do not join. We then apply the framework to explore qualitatively the reasons why this pattern occurs.

Patrick Kelly: Fashions’ great black hope
Authors: Lewis Van Dyk , Fraley Keith A.
Published: July 2015

When blackness is received by an industrial cultural organization it is subject to degradation of meaning and effect. Black designers wishing to operate in the upper echelons of the fashion industry must reconnoiter their positions by employing self-sabotage and offer less potent versions of operational blackness. This article unpacks how blackness is operated and mythologized within the Parisian fashion system. The authors investigate Patrick Kelly’s passage from obscurity to prominence as being in keeping with the Hegelian master–slave dialectic. The importance of this unpacking is timely as black fashion designers are increasingly breaching an exclusion zone that placed them formally outside the mainstream fashion system.
Dump it out! An enquiry into consumers’ everyday fashion discourses through handbag
Authors: Lam Magnum , Lam Yee-Nee , Liu Wing-Sun
Published: July 2015

Handbag is an iconic fashion accessory in our material culture. Following the tradition of representational thinking, this article introduces the handbag as an epistemic consumption object through which to investigate consumer experiences, practices and identity construction in relation to everyday lived discourses. The handbag research involves an examination of participants’ personal belongings inside their bags together with phenomenological interviews concerning the associated subjective experiences along with these material objects. We demonstrate how these material possessions become the subject of the research that facilitates multiple conversations between researchers and participants as to introspect, evaluate and interpret the significance of symbolic consumption in their everyday life. This study contributes to proposing a systematic way of employing interpretive research methodology in the studies of material culture; in addition, this study on the handbag can act as an inspiration for others in identifying emerging themes and topics into symbolism in popular culture.

Electron Cyclotron Resonance Ion Sources (ECRIS) are compact plasma-based machines able to feed particle accelerators with high intensity beams of multi-charged ions. ECRIS plasmas are density-limited, since they are sustained by E.M. wave propagation up to a cut-off density value. In the past, the only way to improve ECRIS performance was to increase the microwave frequency and the magnetic field strength to satisfy the ECR condition. A different plasma heating mechanism is being applied at INFN-LNS. It is based on Electron Bernstein Waves (EBW), i.e., electrostatic waves which do not suffer any density cut-off. Highlights concerning preliminary signatures of EBW formation and subsequent absorption are given here.
COMPARISON OF CLASSICAL AND INTERACTIVE MULTI-ROBOT EXPLORATION STRATEGIES IN POPULATED ENVIRONMENTS
Authors: Kalde Nassim , Simonin Olivier , Charpillet François
Published: July 2015

Multi-robot exploration consists in coordinating robots for mapping an unknown environment. It raises several issues concerning task allocation, robot control, path planning and communication. We study exploration in populated environments, in which pedestrian flows can severely impact performances. However, humans have adaptive skills for taking advantage of these flows while moving. Therefore, in order to exploit these human abilities, we propose a novel exploration strategy that explicitly allows for human-robot interactions. Our model for exploration in populated environments combines the classical frontier-based strategy with our interactive approach. We implement interactions where robots can locally choose a human guide to follow and define a parametric heuristic to balance interaction and frontier assignments. Finally, we evaluate to which extent human presence impacts our exploration model in terms of coverage ratio, travelled distance and elapsed time to completion.
HYDROGENATED TARGETS FOR HIGH ENERGY PROTON GENERATION FROM LASER IRRADIATING IN TNSA REGIME
Authors: Torrisi Lorenzo , Cutroneo Mariapompea , Ullschmied Jiri
Published: July 2015

Polyethylene-based thin targets were irradiated in high vacuum in the TNSA (Target Normal Sheath Acceleration) regime using the PALS laser facility. The plasmais produced in forward direction depending on the laser irradiation conditions, the composition of the target and the geometry. The optical properties of the polymer use nanostructures to increase the laser absorbance. Proton kinetic energies from hundreds keV up to about 3MeV were obtained for optimal conditions enhancing the electric field driving the ion acceleration.
No Fun: The Queer Potential of Video Games that Annoy, Anger, Disappoint, Sadden, and Hurt
Authors: Ruberg Bonnie
Published: July 2015

Game designers and scholars alike commonly claim that video games should be first and foremost fun. At the same time, in reactionary corners of gamer culture, the argument that games should be “just for fun” is shutting down discourse around diversity. However, there is much more to video games than fun. It can be argued that video games are the twenty-first century’s most influential art form, and they can and do engender a wide range of feelings, from joy to sadness, annoyance to rage. Although some researchers, such as ludologist Jesper Juul, have acknowledged the prevalence of unpleasant moments in video-game play, they often make sense of these difficult experiences by reframing them as stepping stones on the road to happiness. In this article, I argue for a different approach to affect in video games, one that focuses on experiences that are “no fun.” Drawing from writing by queer theorist Jack Halberstam, I demonstrate how no-fun emotions disrupt accepted paradigms of video games and heteronormative pleasures more broadly. I conclude with a series of examples of no-fun games that illustrate how affect can communicate meaning as effectively and diversely as a game’s content, and how looking at games that go beyond fun creates new space for players, games, and queer worlds at the margins.
The New Imperialism of Globalized Monopoly-Finance Capital: An Introduction
Authors: Foster John Bellamy
Published: July 2015

It is now a universal belief on the left that the world has entered a new imperialist phase.… The challenge for Marxian theories of the imperialist world system in our times is to capture the full depth and breadth of the classical accounts, while also addressing the historical specificity of the current global economy. It will be argued in this introduction (in line with the present issue as a whole) that what is widely referred to as neoliberal globalization in the twenty-first century is in fact a historical product of the shift to global monopoly-finance capital or what Samir Amin calls the imperialism of "generalized-monopoly capitalism."

The Creation of the Next Imperialism: The Institutional Architecture
Authors: Ghosh Jayati
Published: July 2015

Insofar as imperialism is about the struggle over and capture of economic territory (which must be broadly defined to include not just geographical territory such as land and natural resources, but also the creation of new markets, sources of labor, and forms of surplus transfer such as are reflected in intellectual property), these changes [in imperialism since the early 20th century] have created distant demands upon imperialist structures and processes…. [So] how can capital (which is increasingly global in orientation) generate the superstructures through which the transfers of value are ensured and the investment risks are moderated and contained? It will be argued that there has been an endeavor to resolve this by refashioning the global institutional architecture in ways that operate to increase the conditions of "stability" for large capital while increasing its bargaining power vis-à-vis working people and citizens, as well as nation-states and even smaller capitalist enterprises.

Contemporary Imperialism
Authors: Amin Samir
Published: July 2015

Lenin, Bukharin, Stalin, and Trotsky in Russia, as well as Mao, Zhou Enlai, and Den Xiaoping in China, shaped the history of the two great revolutions of the twentieth century. As leaders of revolutionary communist parties and then later as leaders of revolutionary states, they were confronted with the problems faced by a triumphant revolution in countries of peripheral capitalism and forced to "revise"…the theses inherited from the historical Marxism of the Second International.… With the benefit of hindsight, I will indicate here the limitations of their analyses. Lenin and Bukharin considered imperialism to be a new stage ("the highest") of capitalism associated with the development of monopolies. I question this thesis and contend that historical capitalism has always been imperialist, in the sense that it has led to a polarization between centers and peripheries since its origin (the sixteenth century), which has only increased over the course of its later globalized development.

Imperialism and Anti-Imperialism in Africa
Authors: Campbell Horace
Published: July 2015

When international media were broadcasting live video footage of Tunisians gathering in hundreds of thousands in front of the central office in Tunis of the long-terrifying ministry of home security, chanting in one voice "the people want to bring down the regime," something had already changed: ordinary people realized they could make huge changes. Weeks later, the Egyptian uprising removed the Mubarak regime that had been entrenched in power for over thirty years…. The neoliberal forms of imperial rule that had destroyed the hopes of the liberation movements were under attack. In order to counter the possibilities for a massive breakthrough at the popular level, the Western forces mounted an invasion of Libya using the mantra of humanitarianism to disrupt, militarily, political and economic life in Africa. Later in collusion with the counter-revolutionary forces in the Egyptian military, Western imperialism sought to roll back the gains of people in the streets of Tunis and Cairo.

Resisting the Imperial Order and Building an Alternative Future in Medicine and Public Health
Authors: Jasso-Aguilar Rebeca , Waitzkin Howard
Published: July 2015

Although medical and public health have played important roles in the growth and maintenance of the capitalist system, conditions during the twenty-first century have changed to such an extent that a vision of a world without an imperial order has become part of an imaginable future. Throughout the world, diverse struggles against the logic of capital and privatization illustrate the challenges of popular mobilization. In addition to these struggles, groups in several countries have moved to create alternative models of public health and health services. These efforts—especially in Latin America—have moved beyond the historical patterns fostered by capitalism and imperialism…. All the struggles that we describe remain in a process of dialectic change and have continued to transform toward more favorable or less favorable conditions. However, the accounts show a common resistance to the logic of capital and a common goal of public health systems grounded in solidarity, not profitability.
