What is Legal Logic?
Authors: Perelman Ch. 
Published: June 2019

That the question what is legal logic should still arise today appears paradoxical, for law is after all one of the oldest of human disciplines and logic has in the twentieth century become one of the most developed of the disciplines of contemporary philosophy. Yet comparison of a number of recent works dealing with the subject, all of which, not being without merit, have enjoyed a measure of success, is enough to show that the problem exists and is even strongly disputed.Of four such works, two—those by E. Levi and K. Engisch—do not use the word “logic” in their titles, though they deal with legal reasoning and legal thought. The other two, on the contrary, expressly purport to deal with legal logic. Strangely enough, however, their authors explicitly deny the specific existence of such a discipline, whereas Levi and Engisch underscore, without any hesitation, the specific nature of legal reasoning and the existence of a particular logic, legal logic.Thus in the first paragraph of his work, where Klug attempts to define the concept of legal logic, he states that it comprises the study of the rules of formal logic as used in the judicial application of rules of law (p. 6); that legal logic is therefore practical logic, consisting of the application to law of the rules of pure or theoretical logic which is general logic (p. 7).
The Requirement of Corroboration in Sex Offences
Authors: Sebba L. 
Published: June 2019

Under Israel law a person cannot be convicted for a sexual offence unless there is corroborative evidence. This means that if the accused denies that he has committed the offence, he cannot be convicted solely on the basis of the complainant's evidence.Under English law the requirement is somewhat less rigorous: the judge must merely warn the jury of the danger of convicting without corroboration in such cases. The jury may convict in the absence of corroboration provided such a warning is given. There are, however, even in England, certain statutory offences where the more exacting requirement found in the Israel law is applied (i.e. that corroborative evidence be actually submitted).
Seasonal variation in the biochemical composition of Mytilicola intestinalis
Authors: Williams C. S. 
Published: June 2019

The biochemical constitution of the copepod parasite Mytilicola intestinalis was determined and seasonal changes were detected which, in general, could be correlated with the life-history of the parasite.Biochemical constituents have been discussed in relation to those in other endoparasites and free-living crustaceans. It was concluded that carbohydrates and lipids both formed important stores of energy in M. intestinalis. Protein levels were reduced compared with those in free-living forms.This work forms part of a Ph.D. thesis in the University of London. It was completed during the tenure of a Research Assistantship at The Polytechnic, Regent Street, London W. 1.
Seasonal incidence and development of the cestodeCaryophyllaeus laticeps(Pallas) in the River Avon
Authors: Kennedy C. R. 
Published: June 2019

An account is given of the seasonal occurrence, maturation and population changes ofCaryophyllaeus laticepsin its intermediate hostPsammoryctes barbatusand in its definitive hostLeuciscus leuciscusin the River Avon. Infective larvae were found in the tubificid in all months except August, but occurrence and maturation ofC. laticepsin fish showed a clear seasonal periodicity. Infections were acquired between December and March, the parasite matured in April and May and disappeared by July. Maturation ofC. laticepsappeared to be governed by changes in fish hormone levels. Changes in the parasite population in fish bore no relationship to the availability of infective larvae nor probably to the feeding behaviour of fish but were closely correlated with water temperature changes. The most important factor controlling the dynamics of theC. laticeps–dacesystem appears to be a temperature dependent rejection response to the parasites by dace, and it is suggested that a similar mechanism may operate to control the dynamics of other freshwater fish–tapeworm systems.I should like to thank the Avon and Dorset River Authority, and in particular Mr A. S. Grater, for their help in capturing the fish and for their ready co-operation.
Infections of Toxocara canis in dogs fed infected mouse tissues
Authors: Warren E. G. 
Published: June 2019

Toxocara canis larvae infecting dogs undergo tracheal migration following their ingestion in an experimental intermediate host. Development of the parasite then proceeds to the adult stage in the small intestine. Adult dogs are therefore capable of distributing fertile T. canis ova which, if ingested, could cause larva mirans in humans and other animals.This work was financed by research grants from the University of Queensland and the National Health and Medical Research Council of Australia.

A comparison of two laboratory strains of Eimeria tenella
Authors: Joyner L. P. , Norton C. C. 
Published: June 2019

Two strains of E. tenella (Weybridge and Houghton), which have been maintained by laboratory passage for at least 20 years without exposure to drugs, were compared.Oocyst dimensions and morphology were similar and cross-protection experiments showed that the strains could not be distinguished immunologically.One strain (Weybridge) caused greater caecal haemorrhage than the other when small doses of oocysts were given and was less completely controlled by some quinoline and pyridine drugs.Acknowledgements are due to Dr M. E. Rose of the Houghton Poultry Research Station who kindly made the Houghton strain of E. tenella available to us with details of its maintenance.The statistical calculations were made by Miss C. N. Hebert.
Effect and Persistence of Herbicides Applied to Soil in Puerto Rican Forests
Authors: Dowler Clyde C. , Forestier Wilson , Tschirley F. H. 
Published: June 2019

Six herbicides were applied at 3, 9, and 27 lb/A to the soil in forests of three types in Puerto Rico. The forests differed in soil type, amount and pattern of rainfall, and species composition. Defoliation occurred slowly, but the correlation between percentage defoliation and plants killed was significant at the 1% level of probability. Some defoliation was evident 1 month after treatment and increased slowly during the next 6 to 8 months. The most effective herbicide was 4-amino-3,5,6-trichloropicolinic acid (picloram). Generally, 2-methoxy-3,6-dichlorobenzoic acid (dicamba), 2-methoxy-4,6-bis(isopropylamino)-s-triazine (prometone), and 5-bromo-3-sec-butyl-6-methyluracil (bromacil) were less effective than picloram. Both 2,3,6-trichlorophenylacetic acid (fenac) and 3-(3,4-dichlorophenyl)-l,l-dimethylurea (diuron) were ineffective. Defoliation was greatest and more plants were killed in the driest site.One year after treatment, fenac was the most persistent herbicide in the soil. Herbicides were found to a 36 to 48-in depth within 3 months after application.Herbaceous and woody seedlings were present at all sites within 18 months after herbicide application. There was no definite relationship between herbicidal treatment and secondary succession, except that the number and frequency of successional species were greater on plots having the highest percentage of defoliation.
Physiological Changes Accompanying the Death of Cocklebur Plants Treated with 2,4-D
Authors: Cardenas J. , Slife F. W. , Hanson J. B. , Butler H. 
Published: June 2019

The hypothesis that plants treated with 2,4-dichlorophenoxyacetic acid (2,4-D) die as a consequence of abnormal growth has been examined. Cocklebur (Xanthium sp) plants spot treated on one leaf with 2,4-D show three phases of growth toward death. For the first 2 days after treatment, there is a net weight increase, largely due to abnormal growth of the axis (apex, stem, and tap root). Root and leaf growth are drastically curtailed. Between 2 and 7 days, axis growth continues primarily at the expense of leaf tissue which is induced to senesce, especially the cotyledons. The last phase between 7 and 10 days leads to collapse and withering of plants, and was not examined in detail.Analyses for nitrogenous constituents show the usual mobilization to the axis, with early and large increases in nucleic acid. Both photosynthesis and ion absorption are initially stimulated but decline sharply after the first day. Translocation to leaves and roots is drastically reduced in favor of the proliferating axis.The death of the plant appears to be due to suppression of normal apical growth coupled with induction of abnormal axis growth. Failure to produce new root and leaf tissue plus inadequate nutritional maintenance of existing roots and leaves lead to lack of autotrophism and eventual death. The biochemical basis for these responses appears to be with aberrant nucleic acid metabolism.
Winged Elm Control with Picloram and 2,4,5-T with and without Additives
Authors: Elwell Harry M. 
Published: June 2019

Foliar sprays of 4-amino-3,4,5-trichloropicolinic acid (picloram) controlled winged elm (Ulmus alata Michx.) more effectively than 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). Picloram and 2,4,5-T in a mixture effectively controlled the elm. Sprays of 2,4,5-T with ammonium thiocyanate (NH4SCN) added, and a (1:1) combination of NH4SCN and 3-amino-1,2,4-triazole (amitrole) additive, controlled the elm. Foliar sprays of 2,4,5-T without additives have been relatively ineffective. Soil moisture shortage, followed by watering immediately after treatment of winged elm with 2,4,5-T-C14, increased the translocation of 2,4,5-T as compared to plants maintained in moist or dry soils.Picloram controlled winged elm when applied with an injector or as a soil treatment. The 2,4,5-T diluted in diesel oil, applied as an injector treatment, effectively controlled winged elm.
Competition Between Wheat and Wild Buckwheat
Authors: Fabricius L. J. , Nalewaja John D. 
Published: June 2019

An experiment was conducted comparing wheat (Triticum aestivum L., var. Pembina) and wild buckwheat (Polygonum convolvulus L.) grown alone in pots, in full competition, and in root competition at three levels each of soil fertility and soil moisture, and harvested at three dates.Wheat was a better competitor than wild buckwheat when considering dry matter production. With each succeeding harvest, the dry matter production and the total nitrogen and phosphorus uptake increased more for plants grown alone than in competition. Competition caused a reduction in the nitrogen and phosphorus content of wheat and wild buckwheat at the first harvest, while reductions in dry matter did not occur until the second harvest. Wheat increased in dry matter and nitrogen more than wild buckwheat with each higher level of soil moisture when grown alone but not when in competition. When grown alone or in competition, wheat increased linearly in dry matter production with increases in fertility while wild buckwheat produced maximum dry matter with medium fertility. The total nitrogen increased in wheat and wild buckwheat with each higher level of fertility, while total phosphorus increased only in wheat.Wild buckwheat used less water than wheat to produce a gram of dry matter and per milligram of phosphorus uptake when grown alone, while the plants in competition were intermediate in water usage to plants grown alone. Wild buckwheat and wheat used similar amounts of water per unit of nitrogen uptake when grown alone and increased their water usage when grown in competition. Water efficiency for nitrogen and phosphorus uptake and dry matter production usually decreased with plant maturity and higher soil moisture, and increased with higher soil fertility.
Optimizing an Environmental Observatory Network Design Using Publicly Available Data
Authors: Villarreal Samuel , Guevara Mario , Alcaraz‐Segura Domingo , Vargas Rodrigo 
Published: June 2019

AbstractThere is a need to optimize resources for large‐scale environmental monitoring efforts, especially in developing countries. We tested a flexible framework to optimize the design (i.e., selection of study sites) of an environmental observatory network (EON) using publicly available data for Mexico. This country represents a challenge for designing EONs because of its megadiversity and large climate and ecological heterogeneity. We address three pervasive challenges for designing EONs: (1) How to characterize and delineate ecologically similar areas, (2) how to set geographic priorities to establish new representative study sites, and (3) how to assess the representativeness of current and potential new study sites. We used unsupervised cluster analysis to spatially delineate ecologically similar sampling domains. We identified the most representative sites within each domain using a conditioned Latin Hypercube‐sampling strategy. Finally, we demonstrated the applicability of this approach by assessing the spatial representativeness of the eddy covariance network in Mexico (i.e., MexFlux). At least 84 distributed sampling sites are needed to represent >45% of the spatial heterogeneity of gross primary productivity (GPP) dynamics (i.e., GPP_mean and GPP_cv) and evapotranspiration (ET) dynamics (i.e., ET_mean and ET_cv) at the national level. The current array of MexFlux only represents 3% of GPP and 5% of ET dynamics spatial variability at the national‐level, while the same number of sites organized under an optimal framework nearly doubled these estimates. Our framework is based on a data‐driven approach and publicly available sources of information, so it could be applied anywhere in the world.

Abstract
Bisphenol A (BPA) is a typical endocrine disruptor. Bisphenol S (BPS) has been widely used as a substitute for various plastic materials due to the limited application of BPA. However, it does not mean that BPS is a safe substitute due to the lack of effective evaluation of BPS. In this study, the clinical model of Caenorhabditis elegans (C. elegans) was used to study the effects of BPS on the locomotion behavior, growth, reproduction, lifespan and antioxidant system. Our study found that C. elegans exposed to 0.01 μM BPS could have significantly inhibited locomotion behavior and growth, as well as damaged reproductive and antioxidant systems and lifespan. It is interesting to note that in multi-generational exposure studies, we found that BPS exhibits complex genotoxicity. With the transmission to the offspring, BPS showed more significant inhibition of the head thrashes of the nematode, while the effect on the body bends and body length was gradually weakened. The effect of BPS on the brood size shows different rules according to different concentrations and offsprings. Therefore, the safety of BPS still needs further evaluation, especially the multi-generational genotoxicity.
Standardization of Light Transmission Aggregometry for Diagnosis of Platelet Disorders: An Inter-Laboratory External Quality Assessment

Published: June 2019

AbstractSeveral in vitro platelet function tests are available for the diagnosis of inherited platelet function disorders. Currently, the light transmission aggregometry (LTA) is recommended as one of the first-step tests. LTA is available in most specialized hemostasis laboratories. Although the LTA is accepted as a ‘gold standard’ assay for the evaluation of platelet function, its standardization in the clinical practice is still challenging. The GTH-based THROMKID-Plus Study Group has performed an inter-laboratory trial in Germany and Austria. Five different agonists were selected according to the Scientific and Standardization Committee/International Society on Thrombosis and Haemostasis recommendations and shipped in 3 different sets (one should represent a healthy control and two should simulate platelet function disorders) to 15 specialized laboratories in Germany and Austria. Agonists were analyzed by APACT or PAP4/8 aggregometer using platelet-rich plasma from healthy donors. In addition, laboratory-internal platelet agonists were tested in platelet-rich plasma from a healthy donor. All laboratories (9 used APACT, 6 used PAP4/PAP8) showed very consistent data regarding the maximum percentage of aggregation induced by the tested agonists and identified the differential diagnosis of the simulated platelet function disorders with one exception, which was due to technical problems. In contrast, there was a high variability of the laboratory-internal inductors regarding reagent type, concentrations and pathological cut-off values. Our study showed that the shipment of agonists is suitable for an inter-laboratory survey of LTA. However, there is still a remarkable need for standardization of agonist reagents and their concentration as well as for definition of reference ranges.
Maternal Serum Lipid Trajectories and Association with Pregnancy Loss and Length of Gestation
Authors: Grantz Katherine L. , Elmi Angelo , Pugh Sarah J. , Catov Janet , Sjaarda Lindsey , Albert Paul S. 
Published: June 2019

Objective We characterized lipid trajectories and investigated lipids and rate of pregnancy lipid change with the risk of pregnancy loss or preterm delivery <37 weeks.
Study Design In a secondary analysis of 337 women with one to two prior losses assigned to placebo in a randomized controlled trial at four centers (2007–2012), cholesterol, low- and high-density lipoprotein cholesterol (HDL-C), and triglycerides were measured up to 6 months prepregnancy (time 0) and pregnancy up to 7 visits. Trajectories were created using linear mixed models. Multivariable logistic regression with adjustment for maternal characteristics and cholesterol was performed.
Results Lipids decreased from prepregnancy to 4 to 5 weeks, followed by an increase, and were biphasic or triphasic depending on the lipid component. Between 4 and 8 weeks, for every 1-unit increase in HDL-C, there was a 22% decreased odds of loss <14 weeks (odds ratio: 0.78; 95% confidence interval: 0.60, 0.99) and 24% decreased odds of loss or preterm delivery 14 to <37 weeks (odds ratio: 0.76; 95% confidence interval: 0.60, 0.96).
Conclusion There were no associations with other lipid components or other time points. An impaired rise of HDL-C early in pregnancy may signal maladaptation to pregnancy that is associated with pregnancy loss or preterm delivery.
Ontogenetic variation in salinity tolerance and ecophysiology of coastal dune plants
Authors: Lum Tiffany D , Barton Kasey E 
Published: June 2019

AbstractBackground and AimsGlobal climate change includes shifts in temperature and precipitation, increases in the frequency and intensity of extreme weather events and sea level rise, which will drastically impact coastal ecosystems. The aim of this study is to quantify salinity tolerance and to identify physiological mechanisms underlying tolerance across wholeplant ontogeny in two widespread native coastal plant species in Hawaiʻi, Jacquemontia sandwicensis (Convolvulaceae) and Sida fallax (Malvaceae).MethodsAt the seed, seedling, juvenile and mature ontogenetic stages, plants were exposed to high salinity watering treatments. Tolerance was assayed as the performance of stressed compared with control plants using multiple fitness metrics, including germination, survival, growth and reproduction. Potential physiological mechanisms underlying salinity tolerance were measured at each ontogenetic stage, including: photosynthesis and stomatal conductance rates, leaf thickness, leaf mass per area and biomass allocation.Key ResultsSalinity tolerance varied between species and across ontogeny but, overall, salinity tolerance increased across ontogeny. For both species, salinity exposure delayed flowering. Physiological and morphological leaf traits shifted across plant ontogeny and were highly plastic in response to salinity. Traits enhancing performance under high salinity varied across ontogeny and between species. For J. sandwicensis, water use efficiency enhanced growth for juvenile plants exposed to high salinity, while chlorophyll content positively influenced plant growth under salinity in the mature stage. For S. fallax, transpiration enhanced plant growth only under low salinity early in ontogeny; high transpiration constrained growth under high salinity across all ontogenetic stages.ConclusionsThat salinity effects vary across ontogenetic stages indicates that demographic consequences of sea level rise and coastal flooding will influence population dynamics in complex ways. Furthermore, even coastal dune plants presumably adapted to tolerate salinity demonstrate reduced ecophysiological performance, growth and reproduction under increased salinity, highlighting the conservation importance of experimental work to better project climate change effects on plants.
A Longitudinal Study of Grammatical-Gender Marking in French as an Additional Language
Authors: Edmonds Amanda , Gudmestad Aarnes , Metzger Thomas 
Published: June 2019

Abstract
This investigation responds to the need for longitudinal data-driven research on additional-language (AL) acquisition by examining grammatical-gender marking among AL learners of French during a 21-month period, which included an academic year abroad (LANGSNAP corpus). The analysis of oral production consists of a generalized linear mixed model that examines a range of linguistic and extralinguistic factors shown to be important for gender marking in previous research, as well as a random effect for participant. Results show evidence of both change across time and consistency in the interlanguage. Drawing on variationism and usage-based approaches, we argue that longitudinal investigations that are focused on how learners use their additional language have much to offer our understanding of AL acquisition processes.
