Shared Mobility for Last-Mile Delivery: Design, Operational Prescriptions, and Environmental Impact
Authors: Qi Wei , Li Lefei , Liu Sheng , Shen Zuo-Jun Max 
Published: June 2018

Two socioeconomic transformations, namely, the booms in the sharing economy and retail e-commerce, lead to the prospect where shared mobility of passenger cars prevails throughout urban areas for home delivery services. Logistics service providers as well as local governments are in need of evaluating the potentially substantial impacts of this mode shift, given their economic objectives and environmental concerns. This paper addresses this need by providing new logistics planning models and managerial insights. These models characterize open-loop car routes, car drivers’ wage-response behavior, interplay with the ride-share market, and optimal sizes of service zones within which passenger vehicles pick up goods and fulfill the last-mile delivery. Based on theoretical analysis and empirical estimates in a realistic setting, the findings suggest that crowdsourcing shared mobility is not as scalable as the conventional truck-only system in terms of the operating cost. However, a transition to this paradigm has the potential for creating economic benefits by reducing the truck fleet size and exploiting additional operational flexibilities (e.g., avoiding high-demand areas and peak hours, adjusting vehicle loading capacities, etc.). These insights are insignificantly affected by the dynamic adjustment of wages and prices of the ride-share market. If entering into this paradigm, greenhouse gas emissions may increase because of prolonged car trip distance; on the other hand, even exclusively minimizing operating costs incurs only slightly more emissions than exclusively minimizing emissions.

Authors: Robinson P. M. , MacInnes S. J. , Stanley D. , Ali A. A. 
Published: June 2018

Aim The primary aim of this retrospective study was to identify the incidence of heterotopic ossification (HO) following elective and trauma elbow arthroplasty. The secondary aim was to determine clinical outcomes with respect to the formation of heterotopic ossification. Patients and Methods A total of 55 total elbow arthroplasties (TEAs) (52 patients) performed between June 2007 and December 2015 were eligible for inclusion in the study (29 TEAs for primary elective arthroplasty and 26 TEAs for trauma). At review, 15 patients (17 total elbow arthroplasties) had died from unrelated causes. There were 14 men and 38 women with a mean age of 70 years (42 to 90). The median clinical follow-up was 3.6 years (1.2 to 6) and the median radiological follow-up was 3.1 years (0.5 to 7.5). Results The overall incidence of HO was 84% (46/55). This was higher in the trauma group (96%, 25/26) compared with the elective arthroplasty group (72%, 21/29) (p = 0.027, Fisher’s exact test). Patients in the trauma group had HO of higher Brooker class. The presence of HO did not significantly affect elbow range of movement within the trauma or elective groups (elective arthroplasty, Mann–Whitney U test, p = 0.070; trauma arthroplasty, p = 0.370, Mann–Whitney U test). Conclusion HO after total elbow arthroplasty is seen more commonly than previously reported. We have reported a significantly higher rate of HO in TEAs performed for trauma than those performed electively. Cite this article: Bone Joint J 2018;100-B:767–71.

Published: June 2018

AimsThe sacrum is frequently invaded by a pelvic tumour. The aim of this study was to review our experience of treating this group of patients and to identify the feasibility of a new surgical classification in the management of these tumours.Patients and MethodsWe reviewed 141 patients who, between 2005 and 2014, had undergone surgical excision of a pelvic tumour with invasion of the sacrum. In a new classification, pelvisacral (Ps) I, II, and III resections refer to a sagittal osteotomy through the ipsilateral wing of the sacrum, through the sacral midline, or lateral to the contralateral sacral foramina, respectively. A Ps a resection describes a pelvic osteotomy through the ilium and a Ps b resection describes a concurrent resection of the acetabulum with osteotomies performed through the pubis and ischium or the pubic symphysis. Within each type, surgical approaches were standardized to guide resection of the tumour.ResultsThe mean operating time was 5.2 hours (sd 1.7) and the mean intraoperative blood loss was 1895 ml (sd 1070). Adequate margins were achieved in 112 (79.4%) of 141 patients. Nonetheless, 30 patients (21.3%) had local recurrence. The mean Musculoskeletal Tumor Society (MSTS93) lower-limb function score was 68% (sd 19; 17 to 100). According to the proposed classification, 92 patients (65%) underwent a Ps I resection, 33 patients (23%) a Ps II resection, and 16 (11%) patients a Ps III resection. Overall, 82 (58%) patients underwent a Ps a resection and 59 (42%) patient a Ps b resections. The new classification predicted surgical outcome.ConclusionWe propose a comprehensive classification of surgical approaches for tumours of the pelvis with sacral invasion. Analysis showed that this classification helped in the surgical management of such patients and had predictive value for surgical outcomes. Cite this article: Bone Joint J 2018;100-B:798–805.

Published: June 2018

AimsThe aim of this study was to investigate the changes in femoral trochlear morphology following surgical correction of recurrent patellar dislocation associated with trochlear dysplasia in children.Patients and MethodsA total of 23 patients with a mean age of 9.6 years (7 to 11) were included All had bilateral recurrent patellar dislocation associated with femoral trochlear dysplasia. The knee with traumatic dislocation at the time of presentation or that had dislocated most frequently was treated with medial patellar retinacular plasty (Group S). The contralateral knee served as a control and was treated conservatively (Group C). All patients were treated between October 2008 and August 2013. The mean follow-up was 48.7 months (43 to 56). Axial CT scans were undertaken in all patients to assess the trochlear morphological characteristics on a particular axial image which was established at the point with the greatest epicondylar width based on measurements preoperatively and at the final follow-up.ResultsPreoperatively, there were no statistically significant differences between the trochlear morphology in the two groups (sulcus angle, p 0.852; trochlear groove depth, p 0.885; lateral trochlear inclination, p 0.676; lateral-to-medial facet ratio, p 0.468; lateral condylar height, p 0.899; medial condylar height, p 0.816). Many radiological parameters of trochlear morphology were significantly different between the two groups at the final follow-up, including well-known parameters, such as the mean sulcus angle (Group S, 146.27° (sd 7.18); Group C, 160.61° (sd 9.29); p < 0.001), the mean trochlear groove depth (Group S, 6.25 mm (sd 0.41); Group C, 3.48 mm (sd 0.65); p < 0.001) and the mean lateral trochlear inclination (Group S, 20.99° (sd 3.87); Group C, 12.18° (sd 1.85); p < 0.001). Lesser known parameters such as the ratio of the lateral to medial trochlear length (Group S, 1.46 (sd 0.19); Group C, 2.14 (sd 0.42); p < 0.001), which is a measurement of facet asymmetry, and the lateral and medial condylar height were also significantly different between the two groups (p < 0.001).ConclusionThe femoral trochlear morphology can be improved by early (before epiphyseal closure) surgical correction in children with recurrent patellar dislocation associated with femoral trochlear dysplasia.

Aims The aim of this study was to compare the outcomes of surgery using growing rods in patients with severe versus moderate early-onset scoliosis (EOS). Patients and Methods A review of a multicentre EOS database identified 107 children with severe EOS (major curve ≥ 90°) treated with growing rods before the age of ten years with a minimum follow-up of two years and three or more lengthening procedures. From the same database, 107 matched controls with moderate EOS were identified. Results The mean preoperative major curve was 101° (90 to 139) in the severe group and 67° (33° to 88°) in the moderate group (p < 0.001), which was corrected at final follow-up to 57° (10° to 96°) in the severe group and 40° (3° to 85°) in the moderate group (p < 0.001). T1-S1 height increased by a mean of 54 mm (-8 to 131) in the severe group and 27 mm (-4 to 131) in the moderate group at the initial surgery (p < 0.001), and by 50 mm (-17 to 200) and 54 mm (-11 to 212), respectively, during distraction (p = 0.84). The mean number of complications per patient was 2.6 (0 to 14) in the severe group and 1.9 (0 to 10) in the moderate group (p = 0.040). Five patients (4.7%) in the severe group and three (2.8%) in the moderate group developed a neurological deficit postoperatively (p = 0.47). Conclusion Severe EOS can be treated effectively using growing rods, but the risk of complications is high. Cite this article: Bone Joint J 2018;100-B:772–9.

Is the GDPR and Its Right to Data Portability a Major Enabler of Citizen Science?
Authors: Quinn Paul 
Published: June 2018

Abstract
Citizen science is an emerging trend with an ever greater number of adherents. It involves the collection and contribution of large amounts of data by private individuals for scientific research. Often such data will concern the individuals themselves and will be collected through processes of self monitoring. This phenomenon has been greatly influenced by the Internet of Things (IoT) and the connectivity of a wide range monitoring devices through the internet. In collecting such data use will often be made of the services of various commercial organisations, for example that offer cloud storage services. The possibility of data portability is extremely important in citizen science as it allows individuals (or data subjects) to be able move their data from one source to another (i. e. to new areas of scientific research). This article explores the limits and possibilities that legal rights to data portability offer, in particular the new right as outlined by the European Union’s General Data Protection Regulation. In doing so this article will look at where this right (and how it operates in the international legal context) is able to facilitate the phenomenon of citizen science.
Compressive Wave Propagation in Highly Ordered Granular Media Based on DEM
Authors: Wang Jiao , Chu Xihua 
Published: June 2018

Abstract
In this study, we investigated the propagation of the compressive waves in twp-dimensional highly ordered particle assemblies with different material properties and confining stresses. We focused on the attenuation of velocity amplitude, wave speed and energy dispersion behaviors. The mechanisms of wave propagation through specimens containing inclusions that show different horizontal angles were simulated. The peak velocities change exponentially as a function of time along the wave propagation direction. Energy dispersion exhibits an increasing trend as the angle increases. Then the effects of material parameter on wave propagation speed and the confining stress with the dispersion relations are determined. Finally, the shape of wavefront is studied to show the propagation of stress wave. It is linked to the distribution of equivalent strain. The outer contours of wavefront and strain distribution have the same shape.
Restricted Stock Discounts: An Empirical Analysis
Authors: McConaughy Daniel L. , Hussein Monica , Dow James P. 
Published: June 2018

Abstract
Examining 416 transactions over the 1996 to 2013 time period, we find that size, stock price volatility, block size, price-to-revenue, and EBITDA margin are significantly related to restricted stock discounts. We do not find registration rights or the initial holding period to be statistically significantly related to discounts. Our results suggest that simple correlations or sorting of discounts by various criteria do not capture what factors are statistically significantly related to restricted stock discounts in the complex world of private placement deals.
The diachrony of East Asian prosodic templates
Authors: Salmons Joseph , Zhuang Huibin 
Published: June 2018

AbstractTypical words in some East Asian languages, including Chinese, have reduced historically from disyllabic (CV·CV(C)) to monosyllabic (C(C)V(C)) and then open monosyllables (CV). More recently, in some of those languages, many monosyllabic CV forms again appear as disyllabic (CV·CV). The former developments result from a variety of apparently unconnected segmental changes. In the latter, they often reflect morphological innovations, like compounding and affixation. That is, apparently disparate segmental phonological processes reduced monosyllabic word templates and apparently disparate morphological and phonological processes have created new disyllables, which can all be captured in terms of preferred prosodic templates. We integrate these areal and genetic patterns into a growing literature on prosodic templates in diachrony, expanding the set of languages and patterns. That body of work has focused on sound changes that bring words into alignment with templates while our cases studies also involve clear changes in the templatic structures themselves. Finally, the patterns reviewed here resemble cycles of prosodic change, driven by tensions between reduction and minimal word constraints; we suggest that these phenomena show ‘bare’ prosodic cyclicity without the grammatical or functional ramifications of familiar cycles of change.
Factors Associated with the Number of Substance Abuse Nonprofits in the U.S. States: Focusing on Medicaid Expansion, Certificate of Need, and Ownership
Authors: Noh Shihyun , Brown Catherine H. 
Published: June 2018

AbstractThe Affordable Care Act improved substance abuse service coverage and increased demand for these services. Presumably, these changes also influenced the number of substance abuse nonprofits in states. State decisions for Medicaid expansion have the potential to influence nonprofits' decisions to establish new facilities, increasing the demand for these services. In addition, Certificate of Need (CON), that is, state regulation of new health services and facilities, can affect nonprofits' responses to increased demand for substance abuse services. This study provides evidence that the number of nonprofit substance abuse facilities is negatively associated with state decisions to expand Medicaid and state regulation of new health services and facilities. However, in states with both Medicaid expansion and CON, the number of nonprofit substance abuse facilities tended to increase. In addition, evidence suggests that both nonprofit and for-profit substance abuse facilities are negatively influenced by Medicaid expansion and CON, but positively influenced by the interaction of Medicaid expansion and CON, government spending, racial diversity, median income, and uninsured rates.
Numerical investigation of nonlinear mechanical and constitutive effects on piezoelectric vibration-based energy harvesting
Authors: Cellular Ana Carolina , da Silva Monteiro Luciana L. , Savi Marcelo A. 
Published: June 2018

Abstract
Vibration-based energy harvesting has the main objective to convert available environmental mechanical energy into electrical energy. Piezoelectric materials are usually employed to promote the mechanical-electrical conversion. This work deals with a numerical investigation that analyzes the influence of nonlinear effects in piezoelectric vibration-based energy harvesting. Duffing-type oscillator that can be either monostable or bistable represents mechanical nonlinearities. A quadratic constitutive electro-mechanical coupling model represents piezoelectric nonlinearities. The system performance is evaluated for different system characteristics being monitored by the input and the generated power. Numerical simulations are carried out exploring dynamical behavior of energy harvesting system evaluating different kinds of responses, including periodic and chaotic regimes.
VUV Dissociative Photoionization of Quinoline in the 7–26 eV Photon Energy Range
Authors: Leach Sydney , Jochims Hans-Werner , Baumgärtel Helmut , Champion Norbert 
Published: June 2018

Abstract
The dissociative photoionization of quinoline was studied by photoionization mass spectrometry and ion yield measurements over a synchrotron photon excitation energy range 7–26 eV. The ionic and neutral products were identified with the aid of thermochemical calculations that, in some cases, led to deeper understanding of photodissociation pathways and the determination of upper limits of heats of formation of ionic and neutral dissociation products. A detailed comparison between the 20 eV photon excitation and 70 eV electron impact mass spectra, coupled with estimation of thermochemical appearance energies, leads to assignment of the dissociative ionization cation and neutral products for each detected ion. Reaction schemes for formation of these products are proposed in a number of cases. Ion intensities in the photon and electron impact mass spectra were used to consider extending a rule of charge retention in simple bond cleavage to more complex cases of dissociative ionization.

Desde 2014 la Universidad Autónoma del Caribe –UAC– apoya en la región Caribe, la política nacional de diálogo y construcción de paz en Colombia: un proceso que solo recientemente ha arrojado sus últimas consecuencias políticas e internacionales. Para ello estructuró e implementó la 'Cátedra de la Paz' en Pregrado; creó el conocido como Instituto de Altos Estudios para la Paz; estableció una serie de alianzas nacionales e internacionales, generando actividades y eventos en los que participa la comunidad universitaria, implicándola en el proceso como parte del esfuerzo coordinado para lograr su aceptación social. Este estudio que se presenta, de carácter descriptivo, desarrolla una primera fase de diagnóstico arrojando información obtenida mediante una encuesta realizada a una muestra total de 281 estudiantes de la asignatura Sociedad y Cultura para la Paz durante el año 2016. Se pretende determinar una serie de variables, a saber: a) Pre-saberes y conocimientos que tienen los estudiantes sobre la materia de Historia de Colombia y del propio Conflicto Armado; b) los mecanismos y canales que utilizan estos jóvenes para obtener la información; y c) la percepción concreta del estudiante (y el estudiantado) en cuanto a todo lo referente al Acuerdo de Paz y el Conflicto colombiano.
Der zivilprozessuale Nachweis eines Kartellrechtsverstoßes nach vorausgegangener Verpflichtungszusagenentscheidung
Authors: Thomas Stefan 
Published: June 2018

Zusammenfassung
Das Kartellschadensersatzrecht der EU-Richtlinie und der beiden letzten GWB-Novellen ist geprägt vom Paradigma der Follow-on-Klage nach Erlass einer Abstellungs- oder Bußgeldentscheidung. Sinnbild hierfür ist die gesetzlich angeordnete Feststellungswirkung in § 33b GWB (§ 33 Abs. 4 GWB a. F.). Kartellschadensersatzansprüche sind indes auch ohne vorherige behördliche Feststellung eines Verstoßes möglich, für die § 33b GWB als Beweiserleichterung dann aber ausscheidet. Es können hier ggf. nur die allgemeinen Vermutungs- und Anscheinsbeweise bezüglich des Schadens Anwendung finden, etwa § 33a Abs. 2 GWB oder § 33c Abs. 2 GWB, die u. a. voraussetzen, dass zunächst ein Kartellrechtsverstoß im Zivilprozess bewiesen wurde. Fraglich ist, wie es sich mit Blick auf den Beweis des Verstoßes verhält, wenn die Behörde zuvor eine Verpflichtungszusagenentscheidung nach Art. 9 VO 1/2003 bzw. § 32b GWB erlassen hat. Einerseits hat die Behörde in diesen Fällen erste Ermittlungen durchgeführt, andererseits fehlt es bei dieser Entscheidungsform an der Feststellung eines Verstoßes. Der EuGH hat vor diesem Hintergrund unlängst in seinem „Gasorba“-Urteil angemerkt, dass einer Verpflichtungszusagenentscheidung der Kommission in einem späteren Kartellzivilverfahren die Bedeutung eines „Indizes“ bzw. „Anfangsbeweises“ zukomme. Da der Gerichtshof aber keine weitergehenden Erläuterungen zu diesen Wirkungen gemacht hat und da überdies auch die EU-Kartellschadensersatzrichtlinie zu diesem Problem schweigt, geht der vorliegende Beitrag der Frage nach, welche Bedeutung eine Verpflichtungszusagenentscheidung für den Nachweis eines Verstoßes in einem nationalen Kartellschadensersatzprozess haben kann.

Published: June 2018

Background & Aims: The main restriction in the development of adult-adult Living Donor Liver Transplantation (LDLT) is the risk of morbidity and mortality for donors, which raises ethical questions. The objectives of this study are to review published studies dealing with morbidity and mortality in LDLT and to identify the proposed management and strategies for preventing donor mortality and morbidity in LDLT.Methods: The Medline database was searched from 2000 to 2017 using the MeSH terms “liver transplantation” and “morbidity” or “mortality” in combination with keywords “living donor liver transplantation”.Results: Among the 382 articles obtained, 43 articles were relevant for morbidity, 15 for mortality and 6 for both morbidity and mortality. Twenty-three papers reported donor deaths. The major cause of death was sepsis (30%). Morbidity ranged from 10% to 78.3% depending on the studies.Conclusions: The living donors’ morbidity and mortality is high, currently representing the main restriction in the development of LDLT. Some promising techniques, such as the donor portal vein flow modulation could lead to the further development of LDLT.
