Cock Ale: "A Homely Aphrodisiac"
By Joel A. Klein In a stanza from, “The Young Gallants Tutor, Or, An Invitation to Mirth,” an especially lusty song from the 1670s, the anonymous author praised several particular beverages: “With love and good liquor our hearts we do cheer, Canary and Claret, Cock Ale and March beer.” While Canary Wine, Claret, and Märzenbier are still consumed today, what exactly was Cock Ale? The short answer is that it was an alcoholic beverage made from ale, sack, raisins, and the flesh of a rooster, but..

[[alternative]]The Effects of the Combination of Traditional and Media Teaching Method on Elementary Students’ Learning of Shuttle-cock Kicking
[[abstract]]The purpose of this study was to compare the effects of the teaching method that combines traditional and media teaching on shuttle-cock kicking of three different elementary groups on their understanding of the shuttle-cock kicking, performance in motor skills, and learning satisfaction. Therefore, the most suitable shuttle-cock kicking teaching grade could be identified, and to promote shuttle-cock kicking, a long-history traditional folk sport. The participants were 139 elementary students (55 4th graders, 45 5th graders, and 39 6th graders) who had no prior experience in shuttle-cock kicking. During the experimental period, all participants received eight 40-minute shuttle-cock kicking lessons as well as pretests and posttests on their knowledge and motor skills. The test results were analyzed by one-way ANOVA, ANOCVA and paired-samples t-test to investigate differences between and within the groups. A semi-structured interview was used to investigate the students’ learning satisfaction after the experiment. The findings were: (1) There was no significant difference between groups on the achievement on students’ knowledge of shuttle-cock kicking. (2) There was significant difference between groups on the achievement on students’ motor skills of shuttle-cock kicking. 6th graders were significantly better than 5th graders and 4th graders. (3) The teaching method that combines traditional and media teaching on shuttle-cock kicking teaching gained approval of students and motivated them to continue to participate in shuttle-cock kicking. (4) The teaching method that combines traditional and media teaching on Shuttle-cock kicking teaching was effective for students’ learning of shuttle-cock kicking knowledge and motor skills. (5) The teaching method that combines traditional and media teaching was more favorable for students than traditional teacher-oriented teaching method in physical education. (6) The more suitable shuttle-cock kicking teaching grades were grade four and grade six. The findings of this study suggested that shuttle-cock kicking should be taught on grade four and grade six. In addition, more shuttle-cock kicking teachers should be trained to promote such a good sport.
Key words: the combination of traditional and media teaching method,
shuttle-cock kicking knowledge, shuttle-cock kicking motor skills
Gymelloxes juliusboosi Mielke & Grehan & Cock 2020, sp. nov.
Gymelloxes juliusboosi, sp. nov. (Figs 7a, 7b, 8a, 8b, 9a, 9b, 16, 17, 18, 19a, 19b, 19c, 19d) = Aepytus terea (Schaus): Cock (2003: 50) = Gymelloxes terea (Schaus): Cock (2017: 4) Diagnosis. Gymelloxes juliusboosi, sp. nov., can be distinguished from G. terea and G. prosopus only by examination of the sternite VII and VIII and the male genitalia. In G. juliusboosi, sp. nov., the sternite VII is hourglass shaped and the sternite VIII is membranous, while in all its congeneric species the former structure is rectangular and the second is sclerotized, respectively. The unique, conspicuous, mesal process of the posterior margin of the saccus is diagnostic for G. juliusboosi, sp. nov., while in G. terea and G. prosopus, the homologous structure is represented by two short, apically flat, and peg-like projections lateral to the median (Grehan & Mielke 2017). Description. Male (Figs 7a, 7b, 8a, 8b). Head. Antenna bipectinate with ~32 antenomeres; dorsal surface with lamellate scales, dorsal apex with tuft of longer narrow scales; flagellum inner surface carpeted with sensilla trichodea, outer surface with scattered sensilla chaetica. Eyes prominent, bulging from head. Head vestiture with erect orangish-brown scales over vertex, frons, and mouthparts. Intra antenna-ocular scales short, indistinct from vertex scales. Labial palp short, covering scales short and reddish brown. Thorax. Coloured as the head. Legs. Epiphysis and arolium absent. Forewing length: 18–24 mm; wingspan: 38–49 mm. Forewing dorsally. Elongated, tornus shallow; costal margin straight, slightly concave mid-length, apex blunt, outer margin convex, inner margin slightly convex. Ground colour pale yellowish-brown to light brown; stigma light yellow; when darker markings of light grey present, then basal area distinct greyish-brown concolours to postdiscal, premarginal bands and central patch proximately greyish-brown, and about six greyish-black bands between coastal margin and Sc/Rs. Hindwing dorsally. Orangish-brown, lighter than forewing. Forewing and hindwing ventrally. Uniformly coloured, light orangish-brown, but paler than forewing and without markings. Abdomen (Figs 16–18). Dorsally as the thorax, ventrally lighter; tip of the abdomen with longer scales. Tergum VII slightly narrower and longer than tergum VI. Tergum VIII with convex posterior margin. Sternum VII rectangular and constricted at mid-length. Sternum VIII membranous (see remarks). Male genitalia (Figs 19a, 19b, 19c, 19d). Tegumen (= intermediate plate) slightly distinct, but fused to pseudotegumen and projected dorso-posteriorly to form the digitiform process with the tergal lobes and the pseudotegumen. Saccus U-shaped, projected and tapered anteriorly; anterior margin broad, posterior and lateral margins projecting ventral to form a vertical wall or shelf with a single conspicuous mesal process, apically indented. Tergal lobes sclerotized, digitiform, projected posteriorly with rounded apex, and fused to pseudotegumen. Pseudotegumen rectangular; dorsal projection as for the tegumen; ventrally fused, curved ventrally with ventral apex strongly sclerotized. Valva spatulate, inner surface densely setose, apex rounded. Fultura inferior (= juxta) sclerotized, rectangular, wider than long, lateral and posterior margins slightly concave. Fultura superior (= trulleum) partially sclerotized in two rows of two irregular shaped blotches. Phallus membranous except for distal region covered with numerous spicules. Female (Figs 9a, 9b). Examined only as a photograph. Same pattern as the male, but paler and longer forewing. Forewing length: 47 mm; wingspan: 102 mm. Geographical distribution. Gymelloxes juliusboosi, sp. nov., is only known from Trinidad and Tobago islands (Fig. 20). Ethology. All specimens at the type locality were attracted to light at dusk. Host plant. Unknown. Etymology. Gymelloxes juliusboosi, sp. nov., is dedicated to the late Julius O. Boos (Boos 2010), who shared his deep knowledge of the Lepidoptera and ecology of Trinidad with the third author. Type material. Holotype male with the following labels (separated by forward slashes): / HOLOTYPUS, Gymelloxes juliusboosi C. Mielke, Grehan & Cock des. 2018/ Aepytus (Gymelloxes) terea Schaus male, Det. M.J.W.

(UWIZM CABI.3927); 1 male, Tobago, Charlotteville, at light: 14.–18.VI.1999, R. Hammond leg. (UWIZM). Remarks. The membranous sternite VIII present in Gymelloxes juliusboosi, sp. nov., is an apomorphy, since all other Gymelloxes spp. examined show a sclerotized and undifferentiated sternite VIII. The newly described species is recorded from Tobago (Cock 2017) as well as Trinidad. Records are from both the north and south of Trinidad, mostly from forested situations up to 700 m (Morne Bleu), but one record is from a suburban area (Curepe).Published as part of Mielke, Carlos G.

Letras y Encajes
Letras y Encajes publica su primer número en 1926; esta revista fue fundada por mujeres de la clase dirigente de Medellín, muchas de ellas socias de la institución cultural Centro Femenino de Estudios (Sofía Ospina de Navarro, Teresa Santamaría de González, Ángela Villa de Toro y Alicia Merizalde de Echavarría), a lo largo del tiempo se consolidó como la revista femenina más importante del país, dirigida a mujeres de la clase alta y media, abordaba temas que giraban alrededor del hogar, la religión, la literatura y la moda de la época. La revista circuló mensualmente hasta 1959. Sus principales redactoras eran mujeres, pero contaba con la colaboración ocasional de algunos hombres y con traducciones de autoras y autores extranjeras
Special waste valorization and renewable energy generation under a circular economy: Which priorities?
The European Union regulation for emissions from waste incinerators had a significant evolution in the last 20 years. That allowed reaching a clear improvement in the environmental performances of the plants, synchronized with specific requests of compliance of the more and more stringent limits set at regulatory level. Today the main questions for the sector in Europe seem mostly related to the role of waste to energy plants in a scenario of circular economy and to the role of those plants in the generation of energy only in part renewable. It seems that the topic of the local environmental and health impact has become out to date in European Union. In spite of that, a big question remains on the suitability of the present regulation for the future of the sector, including co-incineration by the use of Secondary Recovered Fuel from waste as substitute of coal in cement works. The present article analyzes an aspect that should be a priority higher than the concept of circular economy and energy generation. Indeed, a question remains on the criticalities that could be present in the European Union for under-estimation of the role of heavy metals, in spite of the evolution of the regulation. If we look at the experience of the University of Trento (where the Author worked in various research projects since 2003) the last decade has been characterized by recurrent warnings from that University about the excessive simplification of the regulation in case of heavy metals. As an example, in case of waste incineration, a set of heavy metals are managed by summing their concentrations to be compared as sum to the regulation limit: no valorization of the specific knowledge on toxicity is made. In order to point out the consequences of this simplification, a few case-studies demonstrating a potential criticality on the role of CrVIare discussed. A control methodology integrating the present one is discussed in this article, to propose a solution suitable to avoid under-estimations of human exposure to heavy metals from incineration and co-incineration. This approach is particularly important when special waste is combusted as the composition of the input can present heavy metals concentrations higher than municipal solid waste
A load of bull - masculinity in Will Self's Cock & Bull
Fascynacja Willa Selfa podmiotowością, przeobrażeniem czy dwoistością znajduje nader reprezentatywny wyraz w parze nowel „Cock & Bull” (1992). Spontaniczna modyfikacja genitaliów głównych bohaterów staje się pretekstem do rozważań o tożsamości płciowej. Koncepcje płciowości przedstawione w „Cock & Bull” mogą sprawiać wrażenie zaskakująco esencjalistycznych, zwłaszcza w kontekście płynności tożsamości, którą wydaje się sugerować transformacja bohaterów. Przekraczanie granic normy służy tu raczej ich jednoznacznemu określeniu niż redefinicji. Zważywszy jednak na przypisywaną autorowi skłonność do satyry, można uznać, że obiektem krytyki stała się w tym wypadku zarówno naiwna wiara w łatwość znalezienia alternatywy dla dominujących modeli tożsamości płciowej, jak i one same. W świecie „Cock & Bull” istnieje jedna płeć – męska. Zwłaszcza w noweli „Cock”, męskość, mimo skojarzenia z agresją i amoralnością, stanowi ucieczkę przed bezsilną i pozbawioną wyrazu antytożsamością kobiecości. Jednocześnie jednak, jak pokazuje transformacja bohatera „Bull”, jest to jednak tożsamość zaskakująco chwiejna i niejednoznaczna.Will Self's fascination with motives of subjectivity, transformation or doubleness is clearly demonstrated by his double novella “Cock & Bull” (1992). The spontaneous modification of the main characters' genitalia becomes a pretext for a reflection on gender identity. Conceptions of gender presented in “Cock & Bull” may appear surprisingly essentialist, especially in the context of the fluidity of identity seemingly suggested by the transformations experienced by the protagonists. Transcending the limits of the norm allows here rather an unambiguous delineation of these limits than their redefinition. However, considering the tendency for satire ascribed by many to the author, one might conclude that the object of criticism in this case is both a naïve faith in the possibility of finding an easy alternative for the dominant models of gender identity and the models themselves. In the world of “Cock & Bull” there is, in fact, only one gender – the male one. Especially in “Cock”, masculinity, despite its association with aggression and amorality, constitutes a form of escape from the powerless and vague anti-identity of femininity. At the same time, however, as the transformation of the protagonist of “Bull” demonstrates, it is an identity that is surprisingly unstable and ambiguous
