Overtly anaphoric control in type logical grammar

In this paper we analyse anaphoric pronouns in control sentences and we investigate the implications of these kinds of sentences in relation to the Propositional Theory versus Property Theory question. For these purposes, we invoke the categorial calculus with limited contraction, a conservative extension of Lambek calculus that builds contraction into the logical rules for a customized slash type-constructor.Peer ReviewedPostprint (author's final draft

Infinitive Wh-relatives in romance : consequences for the truncation-versus-intervention debate

Romance clitic left dislocation is widespread across all kinds of nonroot contexts, but it is forbidden in infinitive wh-relatives. This article investigates the extent and nature of this restriction and the consequences it raises for the truncation and intervention analyses of the left periphery of embedded sentences. We will show that current proposals cannot account for the whole gamut of data. In consequence, we will propose that infinitive wh-relatives display a maximally syncretic left periphery, whereas infinitive wh-interrogatives have a full-fledged left periphery, crucially involving ForceP, because they are selected by a higher predicate. This crucial difference between infinitive relatives and interrogatives will also be shown to be consistent with the existence of specialized complementizers for the former but not the latte

Prediction of key milk biomarkers in dairy cows through milk MIR spectra and international collaborations.

peer reviewedAt the individual cow level, sub-optimum fertility, mastitis, negative energy balance and ketosis are major issues in dairy farming. These problems are widespread on dairy farms and have an important economic impact. The objectives of this study were: 1) to assess the potential of milk Mid Infrared (MIR) spectra to predict key biomarkers of energy deficit (citrate, isocitrate, glucose-6P, free glucose), ketosis (BHB and acetone), mastitis (NAGase and LDH), and fertility (progesterone); 2) to test alternative methodologies to partial least square regression (PLS) to better account for the specific asymmetric distribution of the biomarkers; and 3) to create robust models by merging large data sets from 5 international or national projects. Benefiting from this international collaboration, the data set comprised a total of 9,143 milk samples from 3,758 cows located in 589 herds across 10 countries and represented 7 breeds. The samples were analyzed by reference chemistry for biomarker contents while the MIR analyses were performed on 30 instruments from different models and brands, with spectra harmonized into a common format. Four quantitative methodologies were evaluated to address the strongly skewed distribution of some biomarkers. PLS was used as the reference basis, and compared with a random modification of distribution associated with PLS (Random-downsampling-PLS), an optimized modification of distribution associated with PLS (KennardStone-downsampling-PLS) and Support Vector Machine (SVM). When the ability of MIR to predict biomarkers was too low for quantification, different qualitative methodologies were tested to discriminate low vs high values of biomarkers. For each biomarker, 20% of the herds were randomly removed within all countries to be used as the validation data set. The remaining 80% of herds were used as the calibration data set. In calibration, the 3 alternative methodologies outperform the PLS performances for the majority of biomarkers. However, in the external herd validation, PLS provided the best results for isocitrate, glucose-6P, free glucose and LDH (R2v = 0.48, 0.58, 0.28, and 0.24). For other molecules, PLS-Random-downsampling and PLS-KennardStone-downsampling outperformed PLS in the majority of cases, but the best results were provided by SVM for citrate, BHB, acetone, NAGase and progesterone (R2v = 0.94, 0.58, 0.76, 0.68, and 0.15). Hence, PLS and SVM based on the entire data set provided the best results for normal and skewed distributions, respectively. Complementary to the quantitative methods, the qualitative discriminant models enabled the discrimination of high and low values for BHB, acetone, and NAGase with a global accuracy around 90%, and glucose-6P with an accuracy of 83%. In conclusion, MIR spectra of milk can enable quantitative screening of citrate as a biomarker of energy deficit and discrimination of low and high values of BHB, acetone, and NAGase, as biomarkers of ketosis and mastitis. Finally, progesterone could not be predicted with sufficient accuracy from milk MIR spectra to be further considered. Consequently, MIR spectrometry can bring valuable information regarding the occurrence of energy deficit, ketosis and mastitis in dairy cows, which in turn have major influences on their fertility and survival

Family businesses from emerging markets and choice of entry mode abroad: insights from Indian firms

Internationalization of family businesses (FBs) is an interesting topic that has received extensive attention in the literature during the last decades. Prior studies emphasized the conservative attitude toward risk of FBs. However, studies addressing international decisions of emerging-market FBs (EMFBs) are still scarce. We investigate whether home and host countries matter when EMFBs choose the entry mode abroad. By doing so, we discern whether they follow the same behavioral pattern as developed-country multinational enterprises (MNEs) or they show a distinctive strategic behavior. Drawing on a sample of 298 foreign market entries carried out by Indian MNEs, our results show that Indian FBs prefer acquisitions instead of greenfield investments. Moreover, host country factors matter, since outward foreign direct investment (OFDI) of Indian FBs in developed markets is associated with a preference for acquisitions, whereas OFDI in developing countries is associated with greenfield investments

Study of phase behavior of epoxy asphalt binders using differential scanning calorimetry

Glass transition parameters can be used to study the miscibility, or lack of it, in polymer-modified asphalt binders. In this study, the contribution of thermodynamics of mixing to glass transition was quantitatively assessed in a differential scanning calorimeter for four asphalt binders partially and fully replaced by an epoxy system. The values of heat capacity (Cp) and, subsequently the glass transition temperature (Tg) of all binders were determined to quantify the miscibility based on the entropic changes. Emphasis was also given to examining the enthalpy of mixing as a function of epoxy system composition during curing to ensure that these binders were completely crosslinked for further analyses. In all cases, the positive deviations of the measured Tg of epoxy-modified asphalt binders (Tg,mix) obtained from the ideal mixing rule led to negative values of the entropy of mixing (ΔSmixc), dictating the presence of internal repulsive forces between the asphalt and epoxy components. Softer binders were associated with binders of low deviations of Tg,mix values from the ideal mixing rule. Lastly, the partial replacement of asphalt binders by the epoxy system increased the Tg and decreased the amount of ΔSmixc, and such performance imposes the formation of immiscible products.</p

Can Family Attributes Explain the Racial Disparity in Living Kidney Donation?

Background: Living donation is a safe, effective treatment for patients with end-stage renal disease (ESRD), yet rates of live kidney donation remain low. Potential transplant recipients may be more inclined to ask a family member for a living donation if they feel familial closeness. Methods: The FACES II and the Living Organ Donor Survey were administered to patients attending pretransplant education to assess individual perceptions of family structure and willingness to request a living kidney donation from a family member. Results: A total of 328 potential transplant recipients were included in the study: 200 (61%) African American and 128 (39%) Caucasian. Approximately half were willing to ask for a living donation. Individual\u27s perception of family cohesion, adaptability, and type as measured by FACES II showed most families were mid-range with optimal cohesion and adaptability. Family cohesion and adaptability showed no association with being willing to request a live donation, but those single/never married were only half as likely to ask for donation (odds Ratio [OR] 0.51; 95% confidence interval [CI] 0.31-0.86, P = .01). Lower education (β = -0.49) and unmarried status (β = -0.31) predicted a lower cohesion score. Conclusion: Family type, cohesion, and adaptability showed no differences across race and was not related to the potential recipient\u27s willingness to ask for a live donation. Although responses by race did not differ, an important finding showed that only half of ESRD patients are willing to ask for a live organ donation, and those patients that were single/never married were less likely to ask for a living donation. Research surrounding this reluctance is warranted
