[ES] La industria ósea postpaleolítica, por lo general, pocas veces ha merecido la atención que se le ha concedido a la fabricada durante el Paleolítico Superior. No obstante una de dichas excepciones serán los denominados ídolos-espátulas con decoración acanalada en su mitad proximal, trabajados sobre tibias de "Capra/Ovis" y procedentes por lo que hasta ahora conocemos de contextos sepulcrales megalíticos. En su morfología deben de señalarse el extremo activo romo, al modo de otras espátulas tan comunes en contextos neolíticos, y el extremo proximal decorado con profundos acanalamientos que conforman motivos geométricos más o menos complejos (espiral, zig-zag, etc.) en unos casos y en menos alguna figura antropomorfa femenina. Los primeros hallazgos se realizaron en la provincia de Álava durante la década de los sesenta, destacando entre ellos los procedentes del sepulcro de corredor de San Martín (Laguardia), a los que se sucedieron otros como los de Kurtzebide, Los Llanos, etc. en el mismo territorio y los importantes conjuntos hallados en distintas provincias de la Meseta Norte y en La Rioja. Todos ellos debido al tipo de contexto del que proceden y las características de los ídolos-espátula ritual dan cierto grado de homogeneidad ideológico o religioso a todo el territorio. No obstante, fuera de este territorio y muy alejados desde el punto de vista geográfico existen otros ejemplares (Tell Halula -Siria-, Sesklo, Agios Petras -Grecia-) que muestran gran similitud tipológica aunque no un nexo de unión entre ambas zonas. Por otra parte, hay que subrayar la notable mayor antigüedad del foco oriental y que el contexto del que proceden no es funerario como en el caso de los ejemplares occidentales.

In this paper, I examine the treatment of competitive profit of professor Varian in his textbook on Microeconomics, as a representative of the “modern” post-Marxian view on competitive profit. I show how, on the one hand, Varian defines profit as the surplus of revenues over cost and, thus, as a part of the value of commodities that is not any cost. On the other hand, however, Varian defines profit as a cost, namely, as the opportunity cost of capital, so that, in competitive conditions, the profit or income of capital is determined by the opportunity cost of capital. I argue that this second definition contradicts the first and that it is based on an incoherent conception of opportunity cost.

Background: This study aimed to examine factors associated with treatment adherence in first-episode psychosis (FEP) patients followed up over 8 years, especially involuntary first admission and stopping cannabis use. Methods: This prospective, longitudinal study of FEP patients collected data on symptoms, adherence, functioning,and substance use. Adherence to treatment was the main outcome variable and was categorized as ‘good’ or ‘bad’. Cannabis use during follow-up was stratified as continued use, stopped use, and never used. Bivariate and logistic regression models identified factors significantly associated with adherence and changes in adherence over the 8-year follow-up period. Results: Of the 98 FEP patients analyzed at baseline, 57.1% had involuntary first admission, 74.4% bad adherence,and 52% cannabis use. Good adherence at baseline was associated with Global Assessment of Functioning score (p = 0.019), Hamilton Depression Rating Scale score (p = 0.017) and voluntary admission (p < 0.001). Adherence patterns over 8 years included: 43.4% patients always bad, 26.1% always good, 25% improved from bad to good. Among the improved adherence group, 95.7% had involuntary first admission and 38.9% stopped cannabis use. In the subgroup of patients with bad adherence at baseline, involuntary first admission and quitting cannabis use during follow up were associated with improved adherence. Conclusions: The long-term association between treatment adherence and type of first admission and cannabis use in FEP patients suggest targets for intervention to improve clinical outcomes.
