Educational Research and Policy-Making. Questions, Challenges and Perspectives for a Pedagogical Debate
No full textThroughout the world countries agree that education is a key matter to responding today’s challenges concerning societies, cultures, economies, health and progress. Our lifetime, even defined “postmodernity”, characterized by wider and wider globalization, referred not only to economic systems but also to technological, sociocultural, political, and biological factors, is involved in an uncontrolled and unstoppable process of continuing and faster changes.
In the first part, G. Aleandri deepens shared education policies and reforms towards lifelong learning and education. Education is essential both for individuals and for socio-economic well-being of countries: it provides knowledge, competencies and skills, essential to participate effectively and to cooperate together in society and to contribute to the growth of economic, scientific and cultural knowledge. OECD (Organization for Economic Co-operation and Development) countries agree that is important to know how efficiently each education policy is adapting to new global challenges and issues. Reform in education is a key question in most countries, but it is important to verify if education reforms actually renew policies, practices and outcomes. The international indicators by OECD offer a comparative framework for analysis, useful for education policies to improve quality in the educational offer. The data analyses show that human capital is one of the most important factors for all countries growth. Aleandri chose some international indicators enclosed in each survey since Education at a Glance 2006 (EAG 2006) till Education at a Glance 2009 (EAG 2009), so we can analyze some data of the same indicator across four years. The hope is that more and more kinds of cooperation and partnership among policy makers, pedagogists and education researchers will be promoted, as well as networking among school institutions, universities, other learning organizations, all stake-holders and private companies too, so to make more shared and finally both contemplated and democratic choices and decisions.
In the second part, L. Girotti considers the complex relationship between research and policies through a pedagogical approach. In fact, this partnership/cooperation needs serious reflection and deep investigation by educational research about related questions and challenges. The pedagogical/educational research can benefit from the relationship with public policies not so much in terms of gaining recognition and/or cultural-political influence but because this relation calls for ethical, scientific and methodological challenges that may help to explain its goals, perspectives and contributions. L. Girotti recognizes this contribution in term of resources to validate the experiences of guidance in school, to sustain the guidance function of education/school system, to formulate public policies for guidance. The aim of this article is to draw attention on this last aspect for stressing pedagogical debate on some research perspectives

Ontology of multi-agents processes of spatial decision
Get PDFIn the paper of Cavezzali, Girotti and Rabino presented at ERSA 2003 conference, features of multi-agent models and their potentiality for the study of territorial phenomena are discussed. Starting from this study, the present paper digs deeper mechanisms of multi-agent systems working, describing their ontology in a more complete and articulated way as possible, and investigating: the properties of the actors, the mechanisms of interaction among actors and between actors and environment. About the environment, particular attention has been paid to the consideration about the various modalities of treatment of territory (from pure physical support to active reactive/cognitive agent in relationship with the other agents). For these modalities, finally, two typical case-studies of multi-agent model are shown: simulation of pedestrian paths choice, the software “Turisti”, and a competitive dynamic of service centres location, “Wilson”

TYPE MATERIAL. — Holotype: MPUR7-3897 (Fig. 3A), H = 4.9 mm, W = 2.3 mm. — Paratypes: MPUR7-3898/2, 4198/1, 4211/90, 4200/40. DERIVATION OF NAME. — Named after the type locality. TYPE HORIZON. — Limy mudstone layers of Galatone Fm at Galatone (Esu et al. 1994; Bossio et al. 1998). TYPE LOCALITY. — Galatone (Lecce, Apulia, Italy) (40°8’27.03”N, 18°03’0.37”E). TYPE AGE. — Chattian (Late Oligocene). DIAGNOSIS. — Small-sized shell, elongately conical, with up to 6 ¼ whorls, moderately convex to slightly flattened in the middle, often providing a faint angulation in the lower part of the whorl. Aperture ovate to quadrangular ovate, adapically rounded to barely angulate. Umbilicate. DESCRIPTION Shell small-sized, solid, elongately conical, more or less turreted, with up to 6 ¼ regularly increasing whorls, moderately convex to slightly flattened in the middle, often providing a faint angulation in the abapical part and a step-like margin adapically, in proximity of the suture. Suture incised, deep. Last whorl high just under two thirds of shell height. Protoconch of c. 480 µm maximum diameter, smooth, consisting of one and a quarter slightly convex whorl (Fig. 2B). Teleoconch glossy, with thin, prosocline to nearly orthocline and rather regularly spaced growth lines gradually appearing after the protoconch. Aperture ovate to quadrangular-ovate, adapically rounded to barely angulate, sometimes slightly thickened inside along the outer lip; peristome simple, continuous, columellar lip smoothly concave, adherent partially to the last whorl, outer lip slightly arched in lateral profile. Sometimes transverse, more or less raised wrinkles, irregularly spaced, occur on the last whorl just before the aperture (Figs 2A; 3 Ac, Bc). Umbilicus open, narrow, and deep. Range dimensions: H = 4.1-5 mm, W = 2.1-2.4 mm, H/W = 1.95-2.08. REMARKS The shell shape of Hydrobia (s.l.) galatoniana n. sp. shows a certain degree of variability, varying from more (Fig. 3B) to less turreted (Fig. 3C), with moderately convex to slightly flattened whorls, and ovate (Fig. 3 Ba) to quadrangularovate aperture (Fig. 3 Aa, Ca). Comparisons of the study material with several members of Hydrobiidae from the literature, and those stored in the rich malacological collection at the Senckenberg Museum of Frankfurt a. M., showed similarity mainly to two species: Hydrobia dubuissonii (Bouillet, 1834) and Hydrobia andreaei O. Boettger in Degrange-Touzin, 1892. Bouillet (1834: captions to pl. 18, fig. 14) gave a good description of H. dubuissonii from the Oligocene of the type locality (Aurillac, France), whilst the accompanying picture is unclear. Lozouet & Maestrati (2012: fig. 183.1-8) supplied good illustrations of French specimens of this species from the Oligocene (Stampian) of the Paris Basin. Hydrobia dubuissonii from Oligocene deposits of France (Aurillac and Paris Basin), and Middle Oligocene (Rupelian) of Vieux-Jone, Belgium, stored at the Senckenberg Museum (SMF 12.1594c, ex coll. O. Semper), differs from H. (s.l.) galatoniana n. sp. in having a conical-pyramidal shape, a more acute spire with more prominent apex, whorls not stepped, narrower, more ovate and adapically more angled aperture, and a narrower umbilicus (cf. Esu & Girotti 2010: pl. 3, fig. 8; Lozouet & Maestrati 2012). Maximum dimensions (H = 4 mm, W = 2 mm) given by Bouillet (1834) for H. dubuissonii from the type-locality are on average smaller than those measured for the Galatone specimens (H = 4.1-5 mm, W = 2.1-2.4 mm). Hydrobia andreaei from Early Miocene localities of France, Cabanac (Pouquet), Aquitanian (SMF 245531/1-245532/1, coll. O. Boettger, ex Degrange-Touzin), Saucats (near Bordeaux), Aquitanian (SMF 245533/9, coll. O. Boettger), Lariey (Saucats), Aquitanian (SMF 245550/2, coll. O. Boettger), and Oligocene (Chattian, Cyrenenmergel) of ṙKolbsheim, Elsass (SMF 245534/24, coll. O. Boettger, ex A. Andreae) (cf. Degrange-Touzin 1892: 181), differs from H. (s.l.) galatoniana n. sp. in having a more cylindrical and elongate shell with more acute apical angle, a shallower suture, the last whorl slightly descending towards the aperture, restricted and provided with a faint ring-like varix close to the outer lip, a narrower and semiovate aperture, columellar margin slightly thickened and more oblique, outer margin well arched, a not deep umbilicus, and on average smaller size (H = 3.75-4.5, W = 1.62-1.75) (cf. Boettger in Degrange- Touzin 1892: pl. 5, figs 1-1c; Lozouet et al. 2001: fig. 9). Hydrobia (s.l.) galatoniana n. sp. is distinct from the coeval Hydrobia dubuissonii hydruntina Esu & Girotti, 2010, from the Upper Oligocene marls of the bauxite quarry at Otranto (Apulia) (Esu & Girotti 2010: pl. 3, figs 1-7), in having a more cylindrical shell, more convex whorls, wider quadrangular-ovate aperture, and on average larger size (holotype of H. dubuissonii hydruntina: H = 3.8 mm, W = 2 mm; mean size: H = 4 mm, W = 2 mm). Quaggiotto & De Angeli (2016: fig. 3.1-3) illustrated some not well-preserved remains of Hydrobia cf. dubuissonii from the Lower Oligocene of Valle del Ponte (Vicenza, northeastern Italy). These specimens are clearly different from H. (s.l.) galatoniana n. sp. for their larger size (H = 7 mm), and more elongate and turreted shell shape.Published as part of Esu, Daniela & Girotti, Odoardo, 2019, Two new oligohaline Hydrobia (s. l.)

Hydrobia ionica Esu & Girotti, 2019, n. sp.
No full textHydrobia (s.l.) ionica n. sp. (Figs 2C, D; 4 A-C) urn:lsid:zoobank.org:act: 8D0FEDB0- E 195-4827- A 3 EF-C 2D25 A 445D1 B Pseudamnicola (Staja) sp. – Esu et al. 1994: 189, pl. 2, fig. 4a. TYPE MATERIAL. — Holotype: MPUR7-3899 (Fig. 4 A), H = 4.5 mm, W = 2.5 mm. — Paratypes: MPUR7 -4197/2, 4199/1, 3900/40. DERIVATION OF NAME. — Named after the Ionian Sea, whose shoreline is near the type locality. TYPE HORIZON. — Limy mudstone layers of Galatone Fm at Galatone (Esu et al. 1994; Bossio et al. 1998). TYPE LOCALITY. — Galatone (Lecce, Apulia, Italy) (40°8’27.03”N, 18°03’0.37”E). TYPE AGE. — Chattian (Late Oligocene). DIAGNOSIS. — Small-sized shell, ovately conical, with up to 5 slightly convex whorls, the last large and elongate. Aperture pear-shaped, relatively high and elongate, adapically barely angulate, somewhat flared and slightly thickened inside. Umbilicus slit-like. DESCRIPTION Shell small, solid, thick-walled, ovately conical, with up to 5 slightly convex whorls, the last large, elongate, exceeding two-thirds of shell height. Early whorls slowly increasing, the last faster and somewhat descending (Figs 2C; 4 Ab, Ba). Suture shallow, oblique between the penultimate and ultimate whorl. Protoconch of c. 410 µm maximum diameter, smooth, consisting of one slightly convex whorl. Boundary to teleoconch distinct by the formation of closely spaced growth lines (Fig. 2D). Teleoconch glossy, with very delicate and thin prosocline growth lines. An axial swelling occurs sometimes in the last whorl towards the aperture. Aperture pear-shaped, high, elongate, adapically barely angulate and abapically rounded, somewhat flared and slightly thickened inside; peristome continuous, columellar lip almost completely adherent to the last whorl, outer lip straight in lateral profile. Umbilicus slit-like. Range dimensions: H = 4-4.5 mm, W = 2.5-2.7 mm, H/W = 1.48-1.8. Provisionally, Esu et al. (1994) assigned this stout form to the subgenus Pseudamnicola (Staja) Brusina, 1897, currently considered a separate genus of the family Hydrobiidae (Harzhauser et al. 2015; MolluscaBase 2018b). Examination of further material allowed distinguishing this species from Staja, which is a Miocene Eastern European taxon rich in several species (cf. MolluscaBase 2018b), characterised by a very small size (dimensional range: H = 1.6-2.5 mm, W = 1-1.2 mm) and a mainly conical shell with regularly growing whorls (cf. Brusina 1897; Jekelius 1944). The assignment of ionica n. sp. to the same genus as galatoniana n. sp. is likely supported by similar conchological characters between the two species, such as hydrobioid shell shape with slightly convex whorls, last whorl higher, ovate-elongate and barely flared aperture, and smooth protoconch. Hydrobia (s.l.) ionica n. sp. differs from H. (s.l.) galatoniana n. sp. in having a more globose shell, a wider apical angle, a smaller protoconch, the last whorl proportionally wider and higher, the aperture more elongate, and a smaller H/W (max) ratio (1.8 vs 2.08). It differs from the coeval H. dubuissonii hydruntina from the Upper Oligocene marls of Otranto bauxite quarry (Esu & Girotti 2010) in being conical-ovate in shape, in having a less acute spire, a proportionally higher last whorl and wider and more elongate aperture. Hydrobia dubuissonii from Oligocene deposits of France and Belgium (see above) differs from H. (s.l.) ionica n. sp. in having a conical-pyramidal shape, a more acute spire and a smaller and more ovate aperture.Published as part of Esu, Daniela & Girotti, Odoardo, 2019, Two new oligohaline Hydrobia (s. l.)
