AbstractBackgroundNerve transfer surgery to restore upper extremity function in cervical spinal cord injury (SCI) is novel and may transform treatment. Determining candidacy even years post‐SCI is ill defined and deserves investigation.ObjectiveTo develop a diagnostic algorithm, focusing on electrodiagnostic (EDX) studies, to determine eligibility for nerve transfer surgery.DesignRetrospective descriptive case series.SettingTertiary university‐based institution.PatientsIndividuals with cervical SCI (n = 45).MethodsThe electronic medical records of people referred to the Plastic Surgery Multidisciplinary Upper Extremity Surgery in SCI clinic from 2010‐2015 were reviewed. People were considered for nerve transfers to restore elbow extension or finger flexion and/or extension. Data including demographic, clinical evaluation, EDX results, surgery, and outcomes were collected and analyzed.Main Outcome MeasurementsEDX data, including nerve conduction studies and electromyography, for bilateral upper extremities of each patient examined was used to assess for the presence of lower motor neuron injury, which would preclude late nerve transfer.ResultsBased on our criteria and the results of EDX testing, a substantial number of patients presenting even years post‐SCI were candidates for nerve transfers. Clinical outcome results are heterogeneous but promising and suggest that further refinement of eligibility, long‐term follow‐up, and standardized assessment will improve our understanding of the role of nerve transfer surgery to restore function in people with midcervical SCI.ConclusionsMany patients living with SCI are candidates for nerve transfer surgery to restore upper extremity function. Although the ultimate efficacy of these surgeries is not yet determined, this study attempts to report the criteria we are using and may ultimately determine the timing for intervention and which transfers are most useful for this heterogeneous population.Level of EvidenceIV
Ice front and flow speed variations of marine-terminating outlet glaciers along the coast of Prudhoe Land, northwestern Greenland
Authors: SAKAKIBARA DAIKI , SUGIYAMA SHIN 
Published: March 2018

ABSTRACTSatellite images were analyzed to measure the frontal positions and ice speeds of 19 marine-terminating outlet glaciers along the coast of Prudhoe Land, northwestern Greenland from 1987 to 2014. All the studied glaciers retreated over the study period at a rate of between 12 and 200 m a−1, with a median (mean) retreat rate of 30 (40) m a−1. The glacier retreat began in the year ~2000, which coincided with an increase in summer mean air temperature from 1.4 to 5.5 °C between 1996 and 2000 in this region. Ice speed near the front of the studied glaciers ranged between 20 and 1740 m a−1 in 2014, and many of them accelerated in the early 2000s. In general, the faster retreat was observed at the glaciers that experienced greater acceleration, as represented by Tracy Glacier, which experienced a retreat of 200 m a−1 and a velocity increase of 930 m a−1 during the study period. A possible interpretation of this observation is that flow acceleration induced dynamic thinning near the termini, resulting in enhanced calving and rapid retreat of the studied glaciers. We hypothesize that atmospheric warming conditions in the late 1990s triggered glacier retreat in northwestern Greenland since 2000.

Published: March 2018

While commonly referring to us as ‘human’, ‘particular’ (μερικαί), or ‘rational’ (λογικαί) souls, in one striking passage, Proclus (In Ti. 3.259.21–7) instead describes us asτὸ πολυπλανὲς καὶ μέχρι τοῦ Ταρτάρου κατιὸν καὶ αὖθις ἀνεγειρόμενον παντοῖά τε εἴδη ζωῆς ἀνελίττον ἤθεσί τε χρώμενον ποικίλοις καὶ πάθεσιν ἄλλοτε ἄλλοις καὶ μορφὰς ζῴων ἀλλαττόμενον πολυειδεῖς, δαιμονίας ἀνθρωπίνας ἀλόγους, κατευθυνόμενον δ’ οὖν ὅμως ὑπὸ τῆς Δίκης καὶ εἰς οὐρανὸν ἀπὸ γῆς ἀνατρέχον καὶ εἰς νοῦν ἀπὸ τῆς ὕλης περιαγόμενον κατὰ δή τινας τεταγμένας τῶν ὅλων περιόδους.a far-wanderer, who descends all the way to Tartarus only to be raised up again, who unfolds all possible forms of life, making use of diverse manners and suffering one passion after another, who takes on the forms of living beings of every sort, daemons, men and irrational creatures, and yet is guided by Justice, ascending from earth to heaven and from matter to intellect, being led round and round in accordance with certain prescribed revolutions of the universe.
The changing global landscape of health and disease: addressing challenges and opportunities for sustaining progress towards control and elimination of neglected tropical diseases (NTDs)

Published: March 2018

AbstractThe drive to control neglected tropical diseases (NTDs) has had many successes but to reach defined targets new approaches are required. Over the last decade, NTD control programmes have benefitted from increased resources, and from effective partnerships and long-term pharmaceutical donations. Although the NTD agenda is broader than those diseases of parasitic aetiology there has been a massive up-scaling of the delivery of medicines to some billion people annually. Recipients are often the poorest, with the aspiration that NTD programmes are key to universal health coverage as reflected within the 2030 United Nations sustainable development goals (SDGs). To reach elimination targets, the community will need to adapt global events and changing policy environments to ensure programmes are responsive and can sustain progress towards NTD targets. Innovative thinking embedded within regional and national health systems is needed. Policy makers, managers and frontline health workers are the mediators between challenge and change at global and local levels. This paper attempts to address the challenges to end the chronic pandemic of NTDs and achieve the SDG targets. It concludes with a conceptual framework that illustrates the interactions between these key challenges and opportunities and emphasizes the health system as a critical mediator.
Rarely reported, widely distributed, and unexpectedly diverse: molecular characterization of mermithid nematodes (Nematoda: Mermithidae) infecting bumble bees (Hymenoptera: Apidae:Bombus) in the USA
Authors: Tripodi Amber D. , Strange James P. 
Published: March 2018

AbstractMermithid nematodes (Nematoda: Mermithida: Mermithidae) parasitize a wide range of both terrestrial and aquatic invertebrate hosts, yet are recorded in bumble bees (Insecta: Hymenoptera: Apidae:Bombus) only six times historically. Little is known about the specific identity of these parasites. In a single-season nationwide survey of internal parasites of 3646 bumble bees, we encountered six additional instances of mermithid parasitism in four bumble bee species and genetically characterized them using two regions of 18S to identify the specific host–parasite relationships. Three samples from the northeastern USA are morphologically and genetically identified asMermis nigrescens, whereas three specimens collected from a single agricultural locality in the southeast USA fell into a clade with currently undescribed species. Nucleotide sequences of the V2–V6 region of 18S from the southeastern specimens were 2.6–3.0% divergent from one another, and 2.2–4.0% dissimilar to the nearest matches to available data. The dearth of available data prohibits positive identification of this parasite and its affinity for specific bumble bee hosts. By doubling the records of mermithid parasitism of bumble bee hosts and providing genetic data, this work will inform future investigations of this rare phenomenon.
Where Swedish polar research began: the Linnaean apostle Anton Rolandson Martin's voyage to Spitsbergen in 1758
Authors: Hagström Jonas 
Published: March 2018

ABSTRACTIn 1758 the renowned Swedish botanist Carl Linnaeus sent his student Anton Rolandson Martin to the Arctic on-board a whaler to collect scientific specimens. He became the first Swedish scientist to sail these northern waters and to set foot on Spitsbergen. But what route did the ship take and where exactly did he land? By using a combination of geographical information in Martin's diary together with latitude and wind directions from his meteorological records the ship's voyage has been reconstructed. The whaler set course directly to the west coast of Spitsbergen and then patrolled waters from there to the eastern flank of the ice fields off Greenland. The ship then returned to Spitsbergen as the whaling season drew to an end. Martin got the chance to set foot on land only once and for just two hours. After recent field work at the presumed locality 258 years after Martin's visit, his descriptions of the islets were checked and a first-hand comparison was made between the rock sample Martin brought home and the local bedrock. The author is now confident that the landing took place on Forlandsøyane islands, situated off the southwestern coast of Prins Karls Forland.
Political and legal antecedents of affirmative action: a comparative framework
Authors: Sommer Udi , Asal Victor 
Published: March 2018

AbstractMuch of the literature on affirmative action is normative. Further, in scholarship that takes an empirical approach to examine this topic, the object of inquiry is typically the ramifications of such provisions – most notably the extent to which they foster social transformation. Yet, we know surprisingly little about the antecedents of affirmative action. This work examines what variables systematically predict affirmative action. We focus on the policy feedback literature and compensatory justice frameworks to examine the effects of democracy, modernisation and globalisation on affirmative action programmes. Time-series cross-sectional analyses of data for hundreds of groups from all over the globe for the period 1985–2003 confirm our hypotheses. This is the first work to examine affirmative action programmes in a large-N framework of such scale. We find that such programmes systematically correlate with democracy, modernisation and globalisation.
Gaps in biodiversity occurrence information may hamper the achievement of international biodiversity targets: insights from a cross-taxon analysis

Published: March 2018

SUMMARYSpecies distribution data are critical information sources when it comes to implementing the multiple Aichi Targets set by the international Convention on Biological Diversity. Although there have been international-scale efforts to aggregate distribution data, the magnitudes and locations of the gaps in biodiversity knowledge remain unclear. In this study, we use a large database, including over 200 000 species occurrence records, to identify knowledge gaps in biodiversity inventories for nine animal taxa in a Mediterranean biodiversity hotspot. Spatial modelling methods were employed to relate the completeness of inventories to population, road and protected area density. The completeness of faunistic inventories was correlated with the amount of protected areas, roads and population density. Despite more than 200 years of faunistic sampling, knowledge of the distributions of most animal taxa is still limited, especially for invertebrates. As the window of opportunity for achieving Aichi Targets 11 and 19 begins to close, means of filling such knowledge gaps are required. We argue that a combination of quantitative tools and citizen science data collection programmes may help inform conservation decisions.
The Visual Conquest of International Law: Brute Boundaries, the Map, and the Legacy of Cartogenesis
Authors: RAJKOVIC NIKOLAS M. 
Published: March 2018

AbstractThe late critical geographer Brian Harley forewarned that modern cartography had come to control and even ‘imprison’ spatial understandings of the earth. Where does this leave international lawyers when they encounter a quintessential ‘World Map’? Quite bluntly: tied to an inscriptive institution that has embodied the modern legibility and visualization of earth space. When speaking about the global arrangements of economic and political power constituted through law, what emerges, therefore, is the need for an expanded spatial literacy among international lawyers that critically engages the graphic legacy and influence of the geometric map. To enhance that literacy, I reach beyond the doctrinal field to engage a powerful spatial critique that has thus far encompassed scholarship across geography, international relations (IR) and sociology. A critique that took impetus over 20 years ago with John Agnew's assertion that modern social science had become captured by a ‘territorial trap’. The article attempts to enrich that critique with Mark Salter's insight on material power, Marshall McLuhan's emphasis on the medium of communication, and Bruno Latour's critique of cartographic naturalism. Specifically, I introduce the concept of cartogenesis as a way of underlining the deeper legacy and consequence of modern cartography, and specifically how the map medium should be grasped as a historical actant that has inscribed a particular ‘ground map’ of international authority. Lastly, the article looks at how geometric mapping now confronts new inscriptive ordering in the forms of transnational lists and contracts, which assert a growing scale of authority over earth space to an extent not seen since the Mercator Projection was recognized as an overriding geographic model.
100 years on: a re-evaluation of the first discovery of microfauna from Ross Island, Antarctica
Authors: Velasco-Castrillón Alejandro , Hawes Ian , Stevens Mark I. 
Published: March 2018

AbstractOver a century ago microfaunal diversity was first recorded by James Murray in lakes at Cape Royds, Ross Island, Antarctica. The report stands as the seminal study for today’s biodiversity investigations, and as a baseline to evaluate changes in faunal communities and introductions. In the present study, Cape Royds lakes were revisited and the mitochondrial c oxidase subunit I (COI) gene and morphology were used to compare diversity of Rotifera, Tardigrada and Nematoda with the records Murray published in the early 1900s. Cyanobacterial mats and the water column were sampled for microfauna from the five largest lakes using methods described by Murray. Across all five lakes similar patterns were observed for species distribution of all three phyla reported by Murray over 100 years ago. Some changes in species assemblages were identified within and between lakes, but there were no new introductions of named species for the Cape Royds region. Some of the species included by Murray in his monograph have been recently redescribed as Antarctic endemics, but others still retain their original name from the Northern Hemisphere holotypes and are also in need of revision to adequately determine the true endemism for these faunal groups.
Impact of meal fatty acid composition on postprandial lipaemia, vascular function and blood pressure in postmenopausal women
Authors: Rathnayake Kumari M. , Weech Michelle , Jackson Kim G. , Lovegrove Julie A. 
Published: March 2018

AbstractCVD are the leading cause of death in women globally, with ageing associated with progressive endothelial dysfunction and increased CVD risk. Natural menopause is characterised by raised non-fasting TAG concentrations and impairment of vascular function compared with premenopausal women. However, the mechanisms underlying the increased CVD risk after women have transitioned through the menopause are unclear. Dietary fat is an important modifiable risk factor relating to both postprandial lipaemia and vascular reactivity. Meals rich in SFA and MUFA are often associated with greater postprandial TAG responses compared with those containingn-6 PUFA, but studies comparing their effects on vascular function during the postprandial phase are limited, particularly in postmenopausal women. The present review aimed to evaluate the acute effects of test meals rich in SFA, MUFA andn-6 PUFA on postprandial lipaemia, vascular reactivity and other CVD risk factors in postmenopausal women. The systematic search of the literature identified 778 publications. The impact of fat-rich meals on postprandial lipaemia was reported in seven relevant studies, of which meal fat composition was compared in one study described in three papers. An additional study determined the impact of a high-fat meal on vascular reactivity. Although moderately consistent evidence suggests detrimental effects of high-fat meals on postprandial lipaemia in postmenopausal (than premenopausal) women, there is insufficient evidence to establish the impact of meals of differing fat composition. Furthermore, there is no robust evidence to conclude the effect of meal fatty acids on vascular function or blood pressure. In conclusion, there is an urgent requirement for suitably powered robust randomised controlled trials to investigate the impact of meal fat composition on postprandial novel and established CVD risk markers in postmenopausal women, an understudied population at increased cardiometabolic risk.
Access to Trade Justice: Fixing NAFTA's Flawed State-to-State Dispute Settlement Process
Authors: LESTER SIMON , MANAK INU , ARPAS ANDREJ 
Published: March 2018

AbstractWithout a properly functioning dispute process, the obligations in a trade agreement may not be worth much. As part of the NAFTA renegotiation, the NAFTA parties should try to fix certain flaws in the NAFTA Chapter 20 dispute settlement process that emerged a few years after NAFTA came into force. Chapter 20 was used regularly in its early years, but usage dropped considerably after panel selection was blocked in a case involving US restrictions on Mexican sugar. In this paper, we examine recent innovations on panel selection in the TPP, CETA, and JEEPA dispute provisions, and draw from those to develop principles that can guide revisions to the NAFTA Chapter 20 panel selection process.

Getting Epoxy Semi-Thin Sections to Stick to Glass Slides
Authors: Ahlstrand Gilbert (Gib) 
Published: March 2018

Abstract
Semi-thin sections don't always want to stick to glass slides, but subbing slides is usually not needed. For sections about 2 μm thick and no larger than 4 mm on a slide, this simple method works well for me:
1) Clean 1x3 inch glass slides with an ethanol rinse, then air dry at room temperature or blow down with a hair dryer. 2) Collect sections on a drop or two of distilled water on the slide, transferred there from the microtome with a clean fine tipped artists brush. Collect about 8-12 sections per drop. 3) Warm the slide beneath the water drop from below using an alcohol lamp, fairly hot, but not to boil, of course. After drying by heating the sections stick quite well. 4) Stain, usually with 0.2 μm filtered toluidine blue, again heating but gently this time, for about a minute, until stain “develops” the section. 5) Rinse that stain off with distilled water from a squirt bottle, even directing the spray right onto the sections to get rid of any precipitate. Dry again gently with flame.
The heating is the trick. There should not be any need for subbing or otherwise treating slides other than cleaning them.
Improved Sectioning of Polymers Using an Oscillating Diamond Knife for Transmission Electron Microscopy
Authors: Harris JD , Vastenhout JS 
Published: March 2018

Abstract
Polymers are viscoelastic materials that can often deform during microtome sectioning. Similar to plastic embedded biological materials, many methods have been developed over the years to not only improve the image contrast of these materials but also to harden the material for improved sectioning during microtomy. Even with these improvements, a common artifact, compression, during the sectioning of this class of materials remains problematic.
Compression is caused by several factors: hardness of the sample, embedding media, wedge angle of the knife, interaction between the diamond and sample surface, section thickness and cutting speed. It has been found that reducing the knife angle from 45º to 35° leads to a reduction in compression. Recent efforts to further reduce the compression of ultra-thin sections have led to the invention of an oscillating diamond knife.
Applications for Automated Particle Analysis
Authors: Anderhalt Robert , Swenson Lara 
Published: March 2018

Abstract
Electron microscopy and x-ray microanalysis are common techniques in many research, development and quality labs (Garratt-Reed and Bell, 2002; Goldstein et al., 2003). As systems become ever more automated, as well as easy to use, new applications for the use of these systems develop and expand. One such application is particle analysis. These “particles” might be small loose fragments that can be applied to a conductive adhesive or a filter, embedded in epoxy and polished, or they can be inclusions within collect an EDS spectrum.
