In this article I want to create a presumption in favor of a nonreductive analysis of emotional phenomenology. The presumption relies on the claim that none of the nonemotional elements which are usually regarded as constitutive of emotional phenomenology may reasonably be considered responsible for the evaluative character of the latter. In section 1 I suggest this is true of cognitive elements, arguing that so-called ‘evaluative’ judgments usually result from emotional, evaluative attitudes, and should not be conflated with them. In section 2 I argue the same holds true for conative attitudes (desires and acts of the will). And in section 3 I briefly mention some salient aspects of the version of nonreductive analysis I lean toward. [less ▲]

Agritourism is promoted as a method of offsetting decline in farm incomes, and is defined in different ways which creates difficulties in attracting tourists. The present research contributes to a better understanding of agritourism, based on evidence in Wallonia (Belgium) and Luxembourg. It does so by studying the image held by four groups of actors: (i) farmers who provide ‘agritourist’ experiences; (ii) promotional organisations; and tourists who both (iii) have and (iv) have not engaged in agritourism. Agritourism is a muddled concept between realities and stakeholder expectations but opportunities exist for targeting particular niche interests. [less ▲]

Kidney transplantation (KTx) represents the best available treatment for patients with end-stage renal disease. Still, the full benefits of KTx are undermined by acute rejection (AR). The diagnosis of AR ultimately relies on transplant needle biopsy. However, such an invasive procedure is associated with a significant risk of complications and is limited by sampling error and interobserver variability. In the present review, we summarize the current literature about non-invasive approaches for the diagnosis of AR in kidney transplant recipients (KTRs), including in vivo imaging, gene-expression profiling and omics analyses of blood and urine samples. Most imaging techniques, such as contrast-enhanced ultrasound and magnetic resonance, exploit the fact that blood flow is significantly lowered in case of AR-induced inflammation. In addition, AR-associated recruitment of activated leucocytes may be detectable by 18F-fluorodeoxyglucose positron emission tomography. In parallel, urine biomarkers, including CXCL9/CXCL10 or a three-gene signature of CD3ε, CXCL10 and 18S RNA levels, have been identified. None of these approaches has yet been adopted in the clinical follow-up of KTRs, but standardization of analysis procedures may help assess reproducibility and comparative diagnostic yield in large, prospective, multicentre trials.

Hemicelluloses and Lignin in Biorefineries provides an understanding of lignocellulosic biomass, which is mainly composed of cellulose, hemicelluloses, and lignin. It promotes the valorization of these molecules in the context of the bioeconomy and presents hemicelluloses and lignin, which are generated in lignocellulosic biorefineries, as the molecules of the future. The viability of these molecules lies in their renewability and potential. This book covers all aspects of hemicelluloses and lignin including structure, biosynthesis, extraction, biodegradation, and conversion. The book also looks ahead to the socioeconomic and environmental value of biobased industry and emphasizes an understanding of the potential of lignocellulosic biomass. [less ▲]

Ces terminaux sont des éléments essentiels dans un réseau de transport intermodal, mais ils ont un coût. Pour être rentable, le coût additionnel engendré par les transbordements doit être compensé par un gain dans les coûts de transport. Or, rien ne garantit a priori que l’opération soit rentable, alors que l’ouverture de nouveaux terminaux est très régulièrement présentée comme une opportunité incontournable dans les discours politiques préélectoraux… [less ▲]

This paper aims to contribute to Distributional Typology, whose explicit aim is to investigate linguistic diversity directly (“what’s where why?”, Bickel 2007), by investigating the typology of (co-)lexicalization patterns using a bottom-up approach to semantic maps. Specifically, we propose a new method for constructing semantic maps on the basis of massive cross-linguistic data, in order to evaluate the effects of (i) inheritance, (ii) language contact, and (iii) other environmental and cultural factors on patterns of polysemy and co-lexicalization. This method allows a fine-grained analysis of the factors that lead to the effects identified by areal lexico-semantics (Koptjevskaja-Tamm & Liljegren, 2017). The semantic map model was initially created in order to describe the polysemy patterns of grammatical morphemes (see Cysouw, Haspelmath, & Malchukov, 2010 for an overview). Although studies using the model cover a wide range of linguistic phenomena, the majority pertained to the domain of grammar (e.g., Haspelmath, 1997; van der Auwera & Plungian, 1998). However, recent studies by François (2008), Perrin (2010), Wälchli and Cysouw (2012), Rakhilina and Reznikova (2016), Youn et al. (2016) and Georgakopoulos et al. (2016) have shown that the model can fruitfully be extended to lexical items. The common denominator in both lines of research is that the semantic maps were usually plotted manually, which, is particularly problematic for large-scale typological studies. In this paper, we show that existing synchronic polysemy data in large language samples, such as ASJP (Wichmann et al., 2016), CLICS (List et al., 2014), and the Open Multilingual Wordnet (Bond & Paik, 2012) can be turned into lexical matrices using Python scripts. From these lexical matrices, one can infer large-scale weighted classical lexical semantic maps, using an adapted version of the algorithm introduced by Regier, Khetarpal, and Majid (2013). This approach is innovative in several respects. First, lexical semantic maps are automatically plotted and inferred directly from a significant amount of cross-linguistic data (cf. Youn et al., 2016). Second, unlike other types of polysemy networks in the field, these maps are structured – respecting the connectivity hypothesis (Croft, 2001) and what we call the ‘economy principle’. As such, they generate more interesting implicational universals and can be falsified based on additional empirical evidence. Finally, weighted lexical semantic maps allow exploring the frequency of polysemy patterns and shared lexicalizations from both a semasiological and an onomasiological perspective, which is hardly achievable with other methods. We apply this method to a case study of verbs of perception and cognition (see Appendix for a provisional semantic map) and we enrich the result with additional cross-linguistic data (Zalziniak et al., 2012). The semantic map method allows one to visualize a structured cross-linguistic polysemy network, and to systematically analyze the types of mapping of lexical items onto this network. More specifically, the method allows one to differentiate between common polysemy patterns attested in unrelated languages and shared polysemy patterns, that is colexification patterns shared among languages in the same area. These results will be compared to (i) geographical and genetic data in order to determine the interaction between lexicalization patterns and areality, on the one hand, and common inheritance, on the other. Our findings will also be compared to (ii) proposed universal generalizations, in order to evaluate their validity and limits, and to (iii) proposed language/culture-specific associations identified in the literature (e.g., Viberg, 1984; Sweetser, 1990; Evans & Wilkins, 2000; Aikhenvald & Storch, 2013), in order to evaluate the degree to which the bottom-up method relying on large language samples matches the results of case-studies conducted by experts.

Background: Artemisia campestris L. (Asteraceae) is a medicinal herb traditionally used to treat hypertension and many other diseases. Hence, this study is aimed to analyze the essential oil of A. campestris L (AcEO) and to investigate the antiplatelet, antioxidant effects and the mechanisms of its vasorelaxant effect. Methods: The chemical composition of AcEO was elucidated using GC/MS analysis. Then, the antioxidant effect was tested on DPPH radical scavenging and on the prevention of β-carotene bleaching. The antiplatelet effect was performed on the presence of the platelet agonists: thrombin and ADP. The mechanism of action of the vasorelaxant effect was studied by using the cellular blockers specified to explore the involvement of NO/GC pathway and in the presence of calcium channels blockers and potassium channels blockers. Results: AcEO is predominated by the volatiles: spathulenol, ß-eudesmol and p-cymene. The maximal antioxidant effect was obtained with the dose 2 mg/ml of AcEO. The dose 1 mg/ml of AcEO showed a maximum antiplatelet effect of, respectively 49.73% ±9.54 and 48.20% ±8.49 on thrombin and ADP. The vasorelaxation seems not to be mediated via NOS/GC pathway neither via the potassium channels. However, pretreatment with calcium channels blockers attenuated this effect, suggesting that the vasorelaxation is mediated via inhibition of L-type Ca2+ channels and the activation of SERCA pumps of reticulum plasma. Conclusion: This study confirms the antioxidant, antiplatelet and vasorelaxant effects of A.campestris L essential oil. However, the antihypertensive use of this oil should be further confirmed by the chemical fractionation and subsequent bio-guided assays. [less ▲]

This paper aims to discuss some aspects of the Marty–Husserl debate about grammar. My suggestion is that the debate is first of all an epistemological debate, that is, a debate about what a priori knowledge is and how it is acquired. The key opposition is between Marty’s Brentanian notion of ‘analytic intuition’ and Husserl’s Bolzanian notion of ideation. As I will argue, the underlying issue is the possibility of a psychological a priori. On the one hand, analytic intuition provides the psychologist with a priori knowledge about empirical facts. On the other hand, ideation provides the logician with entities that are disconnected from empirical facts—entities which are ‘purely logical’. I conclude with some brief remarks on the Brentanian background of both conceptions. [less ▲]

Major and trace element (Rb, Sr, Ba, Zr, Ni, V, Zn, Cr, Y, Ce) compositions are studied in Lower Devonian terrigenous sediments from the Dinant Synclinorium and Ardenne Anticline (Belgian Ardenne). Five cross sections encompassing 148 samples in 19 formations have been studied. In the conventional [Al2O3+Fe2O3-K2O-Na2O]–[K2O]–[FeO+MgO] triangle, the rock compositions plot on the illite – chlorite tie line. This suggests that (1) the mineral association has reached equilibrium in the pressure and temperature range of the postdepositional evolution of the sediments; (2) the chemical system was open and K was a mobile component. Although the original composition of the sediment was modified, the AAFM = Al2O3/Al2O3+FeOt+MgO parameter that reflects the illite - chlorite proportions can be used as a proxy of the source composition. A principal component analysis of the major and trace element compositions permits to define the behaviour of various elements currently used as proxies of various processes. Noteworthy it is shown that Ti, V and part of Cr are correlated with the illite proportion, and part of Cr, together with Zr, with resistate minerals such as quartz, chromite and zircon. The evolution with stratigraphic age in the 5 cross sections of the AAFM proxy reveals that there is a major change in the northern part of the Ardenne Anticline at the limit between the Mirwart Formation and younger formations, corresponding approximately to the Lochkovian to Pragian transition. There is a clear shift from an aluminium-rich source to a more conventional chlorite-rich source. In the paleogeographic evolution of this region the only possible source of the aluminium-rich sediment is the Rocroi Massif. Our results confirm sedimentological and palynological evidence that a “Rocroi Island” existed in the Lochkovian Sea. A decrease in Zr concentrations with distance to the Rocroi Massif also supports this hypothesis. The stratigraphic evolution of several parameters shows local variations that can be attributed to variable streams and depositional conditions in an alluvial deltaic or shallow sea environment.

The premetastatic niche in distant organs prior to metastatic cell arrival emerged as an important step in the metastatic cascade. However, molecular mechanisms underlying this process are still poorly understood. In particular, whether neutrophil recruitment at a premetastatic stage promotes or inhibits metastatic cell seeding has to be clarified. We aimed at unraveling how neutrophil infiltration in lung parenchyma induced by the distant primary tumor influences the establishment of lung metastasis. Elevated neutrophil counts and IL-16 levels were found in premetastatic lungs in a syngenic mouse model using 4T1 tumor cells. 4T1 cell-derived soluble factors stimulated IL-16 secretion by neutrophils. The functional contribution of IL-16 is supported by metastasis burden reduction in lungs observed on instillation of an IL-16 neutralizing antibody. Moreover, IL-16 promotes in vitro 4T1 cell adhesiveness, invasiveness, and migration. In conclusion, at a premetastatic stage, neutrophil-derived IL-16 favors tumor cell engraftment in lung parenchyma. [less ▲]
