Clusia nitida Bittrich & F. N. Cabral 2013, sp. nov.
No full textClusia nitida Bittrich & F. N. Cabral, sp. nov. (sect. Phloianthera) (Fig. 1 & Fig. 2) Diagnosis: Similar to Clusia microstemon, but dry leaves are darker coloured and generally have a shiny surface, the latex channels are denser on the adaxial surface, the midrib is conspicuous as far as to the apex, the petal colour is different and anthers are absent on the lateral part of the disk-like androecium. The new species is also similar to Clusia myriandra from which it differs by the leaf shape, the visibility of the latex channels on the leaves, the shorter peduncle and basal internodes in the inflorescence, the size of the fruits and the lesser number of seeds. Type:— BRAZIL. Roraima: Caracaraí, Parque Nacional do Viruá, White-sand vegetation, 1º24’50.7”N, 60º59’16.5”W, 59 m, 15 October 2010, F.N. Cabral & V . S. Santos 298 (holotype INPA!). Trees, small trees or shrubs up to 6 m tall; sometimes with prop roots. Plants dioecious, latex white or cream; young branches cylindrical or more frequently subangular, surface not rugulose, but finely sulcate or with tiny longitudinal foldings, linear colleters present in the petiole axils, deciduous with the leaves. Petiole 4.0–16.0(– 17.0) mm long, margin flat to revolute. Leaf blade coriaceous, discolorous, adaxial surface dark brown and shiny in sicco, oblong-elliptic, 40–85(–108) mm long and (18–)21–49(–53) mm wide, apex rounded, base attenuate, margin revolute; midrib prominent on the adaxial surface and conspicuous as far as the apex, secondary veins prominent on both surfaces, with (9–)12–26(–29) pairs, 1.5–4.0 mm distant from each other and at an angle of 35º–40º with the midrib, basal veins inconspicuous; latex canals concolorous on the adaxial surface or slightly darker than the blade, immersed, 0.3–0.7 mm distant from each other, flat to protruding on the abaxial surface, 0.8–1.0 mm distant from each other, forming an angle of about 25º with the midrib. Inflorescence cymose, compact, 3–9-flowered (staminate plants) or 3–7-flowered (pistillate plants), bracts and bracteoles united at the base, hemiorbicular, ca. 2 mm long, pedicels very short, ca. 2 mm long, quadrangular. Epicalyx bracts 2 (+2), united at base, sepals 4 (2+2), rarely 5 or 6 (2+3, 3+3), ± suborbicular, ca. 4–8 mm long and 4–8 mm wide. Petals 5–8, 6–13 x 6–12 mm, dark bordeaux or blood-red. Staminate flower with the androecium forming a thick, circular, flat disk, ca. 3–6 mm wide, composed of about 300 densely compact stamens, the upper surface covered by a mixture of resin and pollen during anthesis, filaments 2.3–3.0 mm long, lateral region of the disk without anthers, anther dehiscence by apical or transverse slits. Pistillate flower with 3 or 4 series of staminodes around the base of the ovary, secreting resin at the apex; staminodes linear, 1.3–2.0 mm long, truncated at the apex, without sterile anthers; stigmas 4 or 5, apical, yellowish, obtusely triangular, flat, 2.5 mm long; ovary yellow, ovules 1 or 2(–3) per locule. Immature fruit oval to hemispherical, 15–22 x 13–19 mm, usually finely longitudinally striate with latex canals; sepals, staminodes and stigmas persistent, valve endocarp not conspicuously hardened. Seeds 1 or 2(–3) per locule, 5.0–9.0 x 3.5–5.0 mm, green, aril orange. Comparison: —The most similar species is C. microstemon Planchon & Triana (1860: 331), which sometimes occurs sympatrically, and with which C. nitida has been confused. It has a wide distribution in the Amazon. The main difference between the species is the male androecium, which in C. microstemon has anthers at the lateral side of the androecial disk, whereas C. nitida has anthers only on its top. Other differences include the darker colour and the glossy appearance of the leaf surfaces in sicco in C. nitida; the androecium size, which is larger in C. microstemon; the flower colour, in C. microstemon the petals are reddish to pinkish-purple in the centre and white-pink on the edge and the calyx is white-pink, while in C. nitida the petals are dark bordeaux or blood-red and the calyx is green; C. microstemon has 4 or 5 ovules per locule, whereas C. nitida has only 1 or 2(–3) ovules per locule; the fruits of C. microstemon are slightly ovoid and in C. nitida they are generally cylindrical, and finally, C. microstemon has a lower density of latex channels on the leaves than in C. nitida and the midrib becomes invisible in the apical part of the leaves. Another similar species is C. myriandra (Bentham 1843: 368) Planchon & Triana (1860: 332) from the Guianas, which has a very similar androecium. However, C. myriandra has elongated and oblanceolate leaves, unlike C. nitida, which has shorter and more rounded broader leaves; the latex channels of the leaves, which are easily visible in C. nitida, are invisible in the strongly coriaceous leaves of C. myriandra; the peduncle and the basal internodes in the inflorescence are much longer in C. myriandra, positioning the inflorescence above the foliage and C. myriandra has more elongated and larger fruits than C. nitida with 10 or more seeds per locule, while the fruit locules of C. nitida have only 1 or 2(–3). Etymology: —Latin nitidus = shiny, because the dried leaves generally have a conspicuously shiny surface, different from those of C. microstemon, the leaf surface of which is typically dull. Distribution and habitat: —In Brazil, Clusia nitida is known from the North Region, in the states of Amazonas and Roraima. Apparently, it has not yet been collected outside of Brazil. It mainly occurs in whitesand vegetation and at river margins in Amazonian lowlands. Additional specimens examined (paratypes): — BRAZIL.

Informalidad y actividad económica en Uruguay: una mirada de largo plazo
No full textClasificación JEL: E24 – Empleo; Desempleo; Salarios; Estructura del mercado laboral O17 – Economía informal; Subempleo; Economía sumergida C32 – Series temporales; Modelos con variables cointegradas; Modelos de corrección de errores J21 – Análisis de la fuerza de trabajo y del empleo J46 – Economía informal; Autoempleo; Empleo ocultoLa finalidad del presente trabajo es analizar la relación existente entre el empleo informal y el nivel de actividad económica en Uruguay utilizando técnicas de cointegración multivariada. Se busca verificar si se cumple la hipótesis de mercados de trabajo integrados (comportamiento procíclico de la informalidad) o segmentados (comportamiento contracíclico de la informalidad), estudiando si sistemáticamente ha predominado una de ellas en Uruguay entre 1986 y 2015 o si se han alternado en algún subperíodo. La informalidad se aproxima a través de diferentes definiciones, de modo de contrastar diversas hipótesis acerca de su vínculo con la actividad económica: se considera la definición productiva de informalidad y también la definición legalista. Por otro lado, en base a los antecedentes relevados para Latinoamérica, pero particularmente para Uruguay, se profundiza el análisis con foco en los trabajadores por cuenta propia, con el objetivo de estudiar si el patrón de comportamiento dentro de estas categorías de ocupación ha sido homogéneo o si presentan un comportamiento diferente. Los resultados indican que en todos los períodos existe una relación de largo plazo entre la aproximación de informalidad correspondiente y el nivel de actividad económica. El signo de esta relación es negativo en tres de los cuatro casos: informalidad productiva, legalista y cuenta propia sin local, cumpliéndose entonces la hipótesis de mercado segmentados. Por su parte, para los cuentapropistas con local, se evidencia un vínculo positivo entre ambas variables, dando cuenta de un patrón de comportamiento procíclico, lo que sugiere que en vii esta categoría ocupacional parecería operar una lógica diferente que no sería directamente asimilable a la noción de informalidad productiva utilizada en este trabajo. Los resultados se mantienen para todos los subperíodos estudiados, y contribuyen a la comprensión del funcionamiento del mercado laboral, con consecuencias importantes sobre la forma en que se visualiza el fenómeno de la informalidad y su rol en el crecimiento económico, particularmente a la hora de pensar políticas que mejoren las condiciones laborales de estos trabajadores
'To Save Them from the Dangers to their Faith’: Documenting Student Life at Catholic Women's Colleges
No full textThis article focuses on student life at Catholic women's colleges in the United States during the 20th century. These colleges helped acculturate many daughters of immigrants to middle-class American society, at the same time creating a specifically female and Catholic culture on college campuses. This evolving culture, which was characterized by the ideals of femininity, religion, and service, can be reconstructed through documentation from the college archives.Peer reviewe
‘A Well-Balanced Education’: Catholic Women’s Colleges in New Jersey, 1900-1970
No full textBy examining Catholic women's colleges in New Jersey during the period 1900-1970, this paper illustrates the complexity of developing a typology of Catholic women's colleges in the United States. The first Catholic women's college in New Jersey, College of Saint Elizabeth was established in 1899 by the Sisters of Charity; followed by Mount St. Mary's, later known as Georgian Court College, in 1908; Caldwell College in 1939; and Felician, originally a junior college, in 1967. Earlier typologies of Catholic women's colleges have divided them into elite liberal arts institutions and local, vocationally-oriented colleges which served the working and lower-middle-class daughters of immigrants. Using college catalogs and yearbooks from the four New Jersey colleges, this study compiles data on curriculum, the education of faculty, college costs, and student origins, and compares it to similar data from two elite colleges, Trinity in Washington, D.C. and Manhattanville in Purchase, New York. In spite of some pressure to offer vocational courses and the challenge of giving women religious faculty members the opportunity to pursue doctoral degrees, during this period New Jersey's Catholic women's colleges provided a Catholic liberal arts education for white middle-class women not unlike that offered at better known and more prestigious colleges. Only after 1970 did social and demographic changes begin to have an impact on the curriculum and student population of this sector of Catholic higher education.Peer reviewe
Gone and Forgotten? New Jersey's Catholic Junior Colleges
No full textIn the late 1960s, New Jersey had eleven seemingly-thriving Catholic junior colleges; by the mid-1970s, all but one of these colleges had closed. This article analyzes why these institutions appeared and disappeared so quickly, and explores what contribution they made to Catholic higher education. While private junior colleges declined throughout the U.S. during this period, in some respects the situation of New Jersey was unique. Research suggests that the greatest contribution these short-lived institutions made was to the education of women religious.Peer reviewe
Vanished Worlds: Searching for the Records of Closed Catholic Women’s Colleges
No full textThis article presents the results of a survey of the archives of 36 Roman Catholic women's colleges that have closed or merged with other institutions since 1967. The majority of these archives are held by the women's religious communities that originally sponsored the colleges, although about one third are held by universities. These archives are rich resources on the history of women, education, religion, and culture that to some degree have been neglected by scholars who have focused on the history of colleges that are still open. As well as suggesting avenues for future research, this article contributes to the literature on how archives can cope with the voluminous records of twentieth-century institutions, and to emerging scholarship on the relationship of archives and memory. The survey upon which it is based revealed certain limitations on preservation, access, and use of these archives, so the article concludes with recommendations on how to make them more visible.Peer reviewe
Women Academics in England, 1870-1930
No full textBased on the author's dissertation, this article traces the development of the academic profession for women in England in the late 19th and early 20th centuries, focusing on women at Oxford, Cambridge and London universities. Unlike in the United States, where women's role in higher education expanded and then retracted during this period, British women slowly and steadily made inroads into this male-dominated profession.Peer reviewe
