The Song of the Crusade against the Albigensians (1st quarter of the 13th century) and the Treaty of Meaux-Paris (1228). Literary mimesis and legal c…
2020
En aquest article analitzem els mecanismes de la construcció del relat (oficial), des de diversos punts de vista, de la Croada contra els albigesos i l’expoli d’Occitània per França en el transcurs d’aqueixa cruel campanya militar (1r terç del segle XIII). Analitzarem dues fonts textuals que són testimonis d’excepció dels fets i de la construcció i la narració d’aqueix relat, a través de la mimesi historiogràfica en un cas, la Cançó de la Croada contra els albigesos, i, en l’altre, del formalisme d’un text jurídic (document històric, pròpiament dit) del més alt rang, el Tractat de Meux-París (1229), signat pels màxims representants de les dues contraparts. I també analitzarem qui es benefic…

CAN RETURN MIGRATION REVITALISE LATVIA’S REGIONS? FACILITATORS AND BARRIERS TO HUMAN CAPITAL GAINS
2021
Migration researchers from East-Central Europe most often focus on the impact of ‘brain drain’ which is characterised by the loss of human capital from emigration. In this paper focus is placed on the assumption that migrants living abroad gain valuable experiences and education opportunities, that lead to personal growth, facilitate entrepreneurship and psychological resilience, amongst other important skills. This experience may be used for the revitalisation of the less-developed regions the migrants return to. To explore what facilitates or inhibits the fulfil potential of ‘brain circulation’ or gain, we use data from two large-scale surveys of return migrants in Latvia, in-depth interv…
When is there more employment, with individual or collective wage bargaining?
2019
Abstract In a standard Diamond-Mortensen-Pissarides labour market with frictions, the authors seek to determine when there is more employment with individual wage bargaining than with collective wage bargaining, using a wage equation generated by the standard total surplus sharing rule. Using a Cobb-Douglas production function, they find that if the bargaining power of the individual is high compared to the bargaining power of the union, there is more unemployment with individual wage setting and vice versa. When the individual worker and the union have the same bargaining power, if the cost of opening a vacancy is sufficiently high, there is more unemployment with individual wage setting. …
Essential oil of Cyphostemma juttae (Vitaceae): Chemical composition and antitumor mechanism in triple negative breast cancer cells
2019
The genus Cyphostemma (Planch.) Alston (Vitaceae) includes about 150 species distrib- uted in eastern and southern Africa and Madagascar. Some species are used in traditional medicine and their biological activities, including antiproliferative effects against cancer cell lines, have been demonstrated. To date no investigations on Cyphostemma essential oils have been carried out. Essential oils, which play important roles in plant defenses have been demonstrated to be active in the treatment of several human diseases and to enhance bioavability of other drugs. The aim of this paper was to identify the chemical composition of the essential oil of the leaves of Cyphostemma juttae (Dinter &…
Chronic social stress lessens the metabolic effects induced by a high-fat diet
2021
Stress has a major impact on the modulation of metabolism, as previously evidenced by hyperglycemia following chronic social defeat (CSD) stress in mice. Although CSD-triggered metabolic dysregulation might predispose to pre-diabetic conditions, insulin sensitivity remained intact, and obesity did not develop, when animals were fed with a standard diet (SD). Here, we investigated whether a nutritional challenge, a high-fat diet (HFD), aggravates the metabolic phenotype and whether there are particularly sensitive time windows for the negative consequences of HFD exposure. Chronically stressed male mice and controls (CTRL) were kept under (i) SD-conditions, (ii) with HFD commencing post-CSD,…
Behavioral profile of intermittent vs continuous access to a high fat diet during adolescence
2018
Abstract Over the past few years, the effects of a high-fat diet (HFD) on cognitive functions have been broadly studied as a model of obesity, although no studies have evaluated whether these effects are maintained after the cessation of this diet. In addition, the behavioral effects of having a limited access to an HFD (binge-eating pattern) are mostly unknown, although they dramatically increase the vulnerability to drug use in contrast to having continuous access. Thus, the aim of the present study was to compare the effects of an intermittent versus a continuous exposure to an HFD during adolescence on cognition and anxiety-like behaviors, as well as to study the changes observed after …
Long-Term Effects of Postovulatory Aging of Mouse Oocytes on Offspring: A Two-Generational Study1
1999
Aims of this study were to analyze the long-term effects of postovulatory aging of mouse oocytes on 1) reproductive traits of parental (F(0)) and first (F(1))-generation females (pregnancy rate, gestation length, litter size, perinatal death, and sex ratio of offspring) and 2) developmental and behavioral variables of F(1) and second-generation (F(2)) offspring (birth weight and weight gain during preweaning development, postnatal day of attainment of immediate righting, spontaneous motor activity, and passive and active conditioned learning ability). Hybrid (C57BL/6JIco x CBA/JIco) females were artificially inseminated at 13 h (control group) or 22 h (oocyte-aged group) after GnRH injectio…
Reproductive state and care giving in Stegodyphus (Araneae: Eresidae) and the implications for the evolution of sociality
2002
Abstract Cooperative brood care is a rare phenomenon in spiders and is restricted to a few social species, including three in the genus Stegodyphus. Brood care in Stegodyphus begins with regurgitation feeding followed by matriphagy: the young consume the body fluids of their mother causing her to die quickly. Whether such an extreme form of maternal care can become a communal task should depend on physiological or historical preconditions. I investigated whether femaleStegodyphus lineatus feed young or allow matriphagy according to their own reproductive state. Broods of young of two age classes (2 or 10 days after hatching) were isolated or fostered out to adult females that were unmated, …
