Social reform in the fiction of Charlotte Perkins Gilman and Olive Schreiner
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina. Centro de Comunicação e ExpressãoUma das contribuições da crítica feminista tem sido a redescoberta de escritoras que foram por alguma razão esquecidas ou subestimadas nos meios intelectuais e literários. A presente dissertação aborda duas dessas mulheres, (Charlotte Perkins Gilman e Olive Schreiner). Há um século atrás estavam no auge de suas atividades como ativistas sociais, conferencistas, defensoras do movimento de mulheres e escritoras. Nesta dissertação busco resgatar a importância de Gilman e Schreiner durante a época em que viveram discutindo algumas das idéias desenvolvidas nas suas mais influentes obras teóricas
Disagio, paura o xenofobia? Un modello di ricerca azione con le comunità di immigrati
No full textL'articolo esamina gli atteggiamenti e le politiche anti-immigrati negli Stati Uniti e in Europa. Nelle comunità ospitanti gli autoctoni hanno un pregiudizio verso gli immigrati con basso reddito in quanto associano la loro presenza al verificarsi di disordini sociali e questi alla percezione dell'aumento di rischio e di paura della criminalità. tuttavia la maggior parte degli immigrati sono lavoratori impegnati e rispettosi della legge e , rispetto ai nativi, sono più spesso vittime di reati. La ricerca sull'immigrazione è in crescita, ma solo da poco pone attenzione all'influenza della politica e di altre macro-influenze sociali, oltre che alle risposte della comunità di accoglienza all'immigrazione. Per orientare la ricerca-intervento con le comunità di immigrati viene presentato un modello ecologico globale, a più livelli, adattano da Christens e Perkins (2008), che comprende la dimensione socio-culturale, fisica, economica e politica

Hughleechia Perkins 1981
No full textHughleechia Perkins, 1981 Hughleechia Perkins, 1981: 299 (type species Hughleechia giulianii Perkins, 1981, by original designation). Diagnosis. Members of Hughleechia can be recognized by the combination of the short maxillary palpi, the absence of a lateral hyaline border on the pronotum, the arcuate posterior border of the pronotum which lacks distinct posterior angles and has a hyaline border, and the ESDS components of the antennal pocket, including a transgenal ridge (see Perkins 1997 for other characters). Description. Body form elongate oval, depressed. Head with distinct ocelli next to protuberant eyes; dorsum of head flat, frons and clypeus in same plane. Maxillary palpus short, palpomere 1 very small, 2 shorter than or subequal in length to 3, 3 broader than other palpomeres, 4 (last) slightly shorter than 3. Nine antennomeres: 2 basal, 1 small intermediate, 1 small cupule, and 5 pubescent segments forming a compact club. Pronotum with anterior margin weakly rounded in middle, posterior margin much more strongly rounded; anterior and posterior margins with narrow (H. giulianii) or moderately wide (H. gracilis) hyaline border, sides lacking hyaline border; disc with shallow median longitudinal depression which is slightly constricted at midlength; lateral fossulae well developed; pronotal surface with moderately dense and moderately long to very long hairs, except hairs absent in median depression and in lateral fossulae. Elytra ovoid or elongate, fused together at weakly raised suture; each elytron with ca. eight rows of punctures, except rows 6–8 much less distinct than discal rows, sometimes random; each puncture with a short, stiff, recumbent seta (H. giulianii) or a long, slender and flexible seta (H. gracilis) (Figs. 5, 6). Flight wings absent. Prosternum slightly and evenly elevated in midline, not carinate; procoxae contiguous. Mesoventrite narrow to broad between mesocoxae, with or without carinae; hydrofuge pubescent. Metaventrite reduced, length in midline approximately equal to that of mesoventrite; intercoxal process moderately to very broad; metacoxae narrowly (H. gracilis) to widely (H. giulianii) separated; hydrofuge pubescence entirely covering metaventrite, or restricted to lateral areas and narrow band along edge of mesocoxal cavities. Abdomen with seven sternites; intercoxal sternite narrow, or broader than long; sternites 1–4 entirely hydrofuge pubescent, or with hydrofuge pubescence restricted to sides; segment 5 totally hydrofuge pubescent; segments 6 and 7 with a few sparse hairs. Legs rather long. Tarsi long, slender for most of length, but distinctly broadened apically; tarsal formula 5 - 5 - 5; tarsomeres 1–3 very small, combined length slightly longer than, or subequal to length of tarsomere 4; tarsomere 5 longer than other segments combined. Structures examined in microslide mounts (terminology as in Perkins, 1997): Head with distinctive transgenal ridge and more-or-less developed secretion sulcus or pores (Figs. 9, 12, z). Three to four elongate secretion delivery setae in H. giulianii (Fig. 7, a); two or three setae in H. gracilis, shorter than those of H. giulianii, which sometimes become stuck together in dry specimens (Figs. 11–13). Postocular hydrofuge (t) asperite and cuticle with exocrine pores (p) near base of secretion delivery setae. Hypomeral antennal pocket (Fig. 7, 11) well developed, cuticle smooth except microreticulate medially and hydrofuge pubescent anteromedially. Exocrine pores moderately dense in antennal pocket. Hypomeral hyaline border moderately large (Fig. 11, o) to quite large anteriorly (Fig. 7, o), in latter condition it contacts postocular secretion delivery setae. Hypomeral hyaline border posteriorly quite narrow, becoming contiguous with posterior hyaline bor- der. Posterior border of pronotum arcuate such that there are no posterior angles. Hypomeral hyaline border and anterior hyaline border contiguous (H. gracilis), or separated (H. giulianii). Wet-hypomeron well developed. Lateral hyaline border absent. Hypomeral antennal pocket setae slightly (Fig. 7, H. giulianii) to well extended (Fig. 11, H. gracilis) beyond hypomeral hyaline border. Profemur lacking distal spine cluster, spines in this area small, as are others on the profemur.Published as part of Perkins, Philip D., 2007, A revision of the Australian intertidal water beetle genus Hughleechia Perkins (Coleoptera: Hydraenidae), pp. 17-29 in Zootaxa 1527 on pages 19-20, DOI: 10.5281/zenodo.17758

Ochthebius Perkins, 2011, new species
No full textOchthebius (s.s.) zulu, new species (Figs. 11, 12, 20) Type Material. Holotype (male): South Africa: KwaZulu-Natal Province: Nqutu, mountain stream, 28 ° 12 ' S, 30 ° 40 ' E, 14–30 ix 1950, A. H. Newton (NHM). Differential Diagnosis. This species, a member of the Namibiensis group, is similar to O. namibiensis in the lack of "accessory series" on the elytra. The dorsal habitus (Fig. 11) is similar to that of O. namibiensis; differentiated therefrom by the smaller size (ca. 1.71 mm vs. 1.87 mm), the less rounded sides of the elytra, and the less elongate pronotum. An imaginary line connecting the pronotal foveae forms more or less a square in O. zulu, whereas an elongate rectangle in O. namibiensis. The aedeagus of O. zulu (Fig. 12) also clearly indicates a relationship to O. namibiensis; however, the two distinctively differ in shape of the apex of the main piece and shape and size of the distal piece. Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.71 / 0.77; head 0.38 / 0.51; pronotum 0.42 / 0.59, PA 0.52, PB 0.53; elytra 1.07 / 0.77. Color: Black, shining, somewhat aeneous, clothed with distinctive white recumbent or subdecumbent pubescence, maxillary palpi, antennae and legs brunneous, apex of last palpomere and apex of distal tarsomeres darker. Head: Eyes moderately large, in dorsal aspect 8 convex facets in longest series. Ocelli without relief, location vaguely indicated by absence of setae. Interocular foveae deep, width of each slightly less than distance separating them. Frons with small round basomedian fovea. Frons and clypeus with punctures of setal sockets fine, ca. 1 / 2 xef, rather sparse; interstices shining, 1–5 xef, not perceptibly micropunctulate; white recumbent setae about twice as long as average distance between setal sockets. Labrum more densely setiferously punctate that clypeus, anterior margin entire in dorsal aspect, in frontal aspect weakly emarginate in middle 1 / 3 where margin narrowly upturned. Mandible with outer surface bearing rather short tapering curving setae. Pronotum: Anterior margin very shallowly bisinuate, without postocular emarginations or processes, with well-developed bisinuate hyaline border. Widest just behind anterior angles, then sides sinuately attenuate to rectangular posterior angles. Lateral hyaline border moderately wide, beginning at about midlength of lateral depression, edge straight or very weakly arcuate, posteriorly continuing very narrowly along base. Disc with narrow midlongitudinal sulcus constricted at middle, anterior and posterior foveae well developed, all depressions microreticulate within; setiferous punctures moderately sparse, about same size and density of those of frons, interstices strongly shining, without evident micropunctulate ground sculpture. Lateral fossula not deep, densely contiguously punctulate. Lateral depression slightly more densely punctate than reliefs. Elytra: Elongate oval, widest about middle, explanate margin very narrow, narrower than tarsal apex. Apices narrowly separately rounded. Ten distinct series of punctures, no "accessory series". Punctures coarser basally, finer apically, on disc punctures ca. 1 xef, longitudinally separated by 2–3 xpd; each puncture with recumbent whitish seta, length ca 2 x distance between punctures; series not striate-impressed except sutural in distal 1 / 2. Intervals flat, moderately shining, very weakly effacedly alutaceous, width on disc 2– 3 xpd. Venter: Mentum weakly shining, effacedly microreticulate, moderately densely and moderately coarsely sparsely setiferously punctate. Metaventrite and abdominal ventrites 1–5 entirely clothed in dense hydrofuge pubescence. Ventrite 6 shining except very narrow band of hydrofuge pubescence at anterior margin, posterior 1 / 2 with sparse, long setae. Etymology. Named in reference to the geographical distribution.
