The role of language typology on L2 acquisition and learning, Special Issue
No full textThis special issue of the I-LanD Journal aims to explore the role of
language typology on second language acquisition (SLA) and learning.
The contributions to this special issue address the question as to
whether and in which ways typological contrasts of languages play a
crucial role in how events are expressed in adult second language (L2).
In this regard, Slobin (1996), by means of his Thinking for Speaking
hypothesis, argues that differences across languages predispose native
speakers to view and to talk about events differently and this seems to
have important consequences in discourse conceptualisation and
production even at very advanced levels of L2 proficiency.
Research on typological variation across languages has been
conducted for decades and important advances have been made in the
domain. For instance, it is well known that Germanic vs Romance
native speakers differ in the ways they conceptualise and verbalise
events. Consequently, speakers diverge in the preferred perspective
selected with respect to conceptual domains such as aspect, time,
motion, modality, both at the sentence level (von Stutterheim 2003)
and at discourse level (Klein/von Stutterheim 2002; Carroll/Lambert
2006) and this is partly due to the typological properties of languages.
Most studies show the challenges adult L2 learners face in restructuring
these patterns in the process of acquisition of another language with a
different set of patterns. This hard task for learners implies full or
partial crosslinguistic influence (CLI, cf. McManus 2022 for a more
recent overview). The latter, often used interchangeably with transfer
(cf. Odlin 1989, 2003, 2005), refers to the search for similarities/
differences between one’s prior linguistic knowledge (from the L1 or
any other previously acquired languages) and learning, knowledge
and use of the new language (Jarvis/Pavlenko 2010: 1). CLI is a key
component of the L2 learning process, and it seems particularly
relevant when learners try to map L2 words into the concepts of their
L1. In this sense, SLA can be seen as cognitive restructuring (HijazoGascón 2021: 2), since learners can experience a cognitive dissonance
between the L2 lexical items and the L1 notions. The question of
whether L1 typological properties may be transferred or not in the L2
discourse has been largely explored for the cognitive domains of time
(e.g. von Stutterheim 2003 for ongoingness vs boundness; McManus/
Marsden 2017, Giuliano/Anastasio 2021a for time and aspect) and

space (e.g. Cadierno/Ruiz 2006; Hendriks et al. 2008; Carroll et al.
2012; Hijazo-Gascón 2021) and, to a lesser extent, for syntax (e.g.
Giuliano/Anastasio 2021b). More recently, research has also focused
on the co-speech gestures in the expression of events. As such, the
literature shows that the ways L2 learners’ gestures can reveal how
they keep on gesturing as in their L1 rather than in the L2 native-like
manner (e.g. Gullberg 2009; Stam 2018, 2023).
In spite of the evident role of inter-typological contrasts during the
process of SLA (along with other important variables such as the L2
input exposure, the L2 proficiency level, individual factors) in terms of
CLI, there is little research that focuses on the impact of intratypological variation, i.e. typological differences or similarities
between languages of the same type (except for Ibarretxe-Antuñano
2009, 2015; Anastasio 2018, 2019, 2021, 2022). Additionally, the
impact of language typology is still far from being fully understood
and this is due to several reasons: a) native speakers’ preferences go
beyond the clear-cut typological classification when encoding the
intended message (Slobin 2006; von Stutterheim et al. 2009; Beavers
etal. 2010); b) most studies look at learners with an L1/L2 combination
belonging to different genetic and typological families and very few
consider the impact of the L1 when the learners’ languages in contact
are typologically close (except for Benazzo/Andorno 2017; Anastasio
2019, 2021, 2022; Saturno 2020; Hijazo-Gascón 2021) and can,
however, lack equivalent form-function categories.
This special issue brings together recent empirical research on
inter- and intratypological contrasts and their role on L2 acquisition
and learning. Specifically, drawing upon a functional perspective, this
special issue aims to add to the SLA field by offering recent empirical
studies relying on original data, involving: different types of tasks;
quantitative, qualitative and mixed-methods approaches; learners at
all stages of learning.
The key themes under focus explore morphological, syntactic, and
semantics differences between languages with their consequences for
framing events in L1 as well as in L2. In particular, three main domains
are investigated: a) affectedness; b) differential object marking; c)
space (static and dynamic location events). The data collected
represent a diversified selection of L1-L2 pairs: a) learners whose L1
and L2 are typologically and genetically closely-related (Isabel Repiso;
Jacopo Saturno); b) learners with an L1-L2 combination considered as
typologically distant (Christina Piot, Maria Hellerstedt); c) learners
whose L1 and L2 belong to different typological types but present
similarities in the linguistic devices for conveying events (Delia
Airoldi).
The first paper of this special issue deals with a still underexplored
domain in SLA functional approach, i.e. affectedness within Romance
languages. Specifically, Isabel Repiso examines the syntactic and
morphological realisation of affected arguments across two
typologically and genetically-related languages, French and Spanish,
and in L2 French of Spanish learners (A2-B2 levels of CEFR). The
crosslinguistic findings show different morpho-syntactic preferences
in French and Spanish productions to mark affectedness. As to L2

Introduction: The Role of Language Typology on L2 Acquisition and Learning
results, CLI arises in terms of under/overuse of non-native like use of
L2 structures especially at less advanced stage. The author hypothesises
that, when confronting to the L2 verbalisation of a universal domain,
learners tend to rely on L2 constructions similar to those of the L1 as
a strategy to compensate lack of knowledge regarding TL uses.
Jacopo Saturno’s contribution also explores the morphosyntax
domain, by focusing on the differential object marking in nominal
morphology in L2 Polish of East Slavic learners (L1: Belorussian,
Russian, Ukrainian) of A1-B1 proficiency (CEFR). By means of a
quantitative study, the author confirms that CLI and universal
tendencies, such as markedness, may coexist as explanatory factors in
the differential object marking in an intercomprehension situation.
The subsequent three papers concern the role of typological
diversity in the expression of space in language. Christina Piot focuses
on multimodality in motion event construal. She first examines how
native speakers (French vs Dutch) express the same motion events in
their speech and co-speech gestures and then to what extent
multimodal and inter-/intralinguistic differences impact performances
of CLIL French learners of L2 Dutch (A1-B2 proficiency levels).
Participants were recruited in Belgium, whose context is not
particularly favourable for monolingual speakers, since it offers three
official languages: Flemish/Dutch speaking; Walloon/French speaking;
and, to a lesser extent, Ostbelgien German speaking. Analysis of
language use and gesture by native speakers shows not only
prototypical features of typological classifications, but also patterns
which are less typical of their language-category. As for L2 performance,
learners have their own thinking-for-speaking pattern which is inbetween the French and the Dutch tendencies. Moreover, the study
also highlights that gestures give information on event
conceptualisation.
With respect to a different language combination, Delia Airoldi’s
contribution also focuses on the expression of motion. Specifically, the
author compares the productions of native speakers of Italian and
German to the productions of German learners of L2 Italian
(intermediate and advanced) by using different types of stimuli. The
aim is to study inter- and intra-linguistic differences between German
and Italian and to see whether learners’ productions are target-like in
L2 motion event construal or still influenced by the L1 patterns.
In the final paper, Maria Hellerstedt discusses two types of space:
location and caused motion, as described by French and Swedish
native speakers and by intermediate and advanced French learners of
L2 Swedish. The larger goal is to investigate the semantic components
selected to describe static and dynamic location in L2 Swedish, namely
by means of posture verbs, and to identify learners’ strategies
(avoidance, over-using) justifying learners’ linguistic choices. On the
one hand, the paper shows the developmental trajectory of L2 Swedish
learners in the use of posture verbs in spatial events. On the other
hand, it highlights traces of CLI and other interlanguage strategies in
producing idiomatic posture verbs.
Taken together, the above contributions bring a timely update within
the research field of typology and L2 acquisition and learning by

particular, these papers provide empirical studies on different

Von Brunn’s Nests in the Ureter of Two Cats
No full textThe aim of this work is to emphasize the importance of a differential diagnosis
of von Brunn’s nests in cats from other urothelial neoplastic disorders, as
transitional cell carcinoma, for a subsequent optimal care. Von Brunn’s nests
and cysts are submucosal benign urothelial processes, related to irritative stimuli
(calculi and urinary infections), characterized by an invagination with
buds and clusters of normal urothelium in the lamina propria. They are
common findings in the urinary bladder of human beings, but few cases have
been described in dogs and cats. We report macroscopic, histopathological
and, in one case, immunohistochemical features of these rare forms in the left
ureters of two cats. Macroscopic evidence during surgery of ureteral nodules
in two cats was accompanied by histopathological diagnosis and, in one case,
by immunohistochemical assessment. Histopathology was coherent with a
rare condition characterized by nests and islands of normal urothelium in the
lamina propria and submucosa, with formation of cysts and moderate focal
subacute inflammation. In one case epithelial cells of the nests showed well differentiated
urothelial cells with an intense immunoreactivity to pan-cytokeratin
(CK AE1/AE3), CK19 in the first outer layers, a slight immunoreactivity to
CK20 and a low proliferative activity using MIB-1 (Ki67)
LHCBM1 and LHCBM2/7 polypeptides, components of the major LHCII complex, have distinct functional roles in the photosynthetic antenna system of Chlamydomonas reinhardtii
No full textThe photosystem II antenna of Chlamydomonas reinhardtii is composed of monomeric and trimeric complexes, the latter encoded by LHCBM genes. We employed artificial microRNA technology to specifically silence the LHCBM2 and LHCBM7 genes, encoding identical mature polypeptides, and the LHCBM1 gene. As a control, we studied the npq5 mutant, deficient in the LHCBM1 protein. The organization of LHCII complexes, functional antenna size, capacity for photoprotection, thermal energy dissipation and state transitions, and resistance to reactive oxygen species was studied in the various genotypes. Silencing of the LHCBM2/7 genes resulted in a decrease of an LHCII protein with an apparent molecular mass of 22 kDa, whereas silencing/lack of LHCBM1 caused the decrease/disappearance of a 23-kDa protein. A decrease in the abundance of trimeric LHCII complexes and in functional antenna size was observed in both LHCBM2/7 and LHCBM1 knockouts. In agreement with previous data, depletion of LHCBM1 decreased the capacity for excess energy dissipation but not the ability to perform state transitions. The opposite was true for LHCBM2/7, implying that this polypeptide has a different functional role from LHCBM1. The abundance of LHCBM1 and LHCBM2/7 is in both cases correlated with resistance to superoxide anion, whereas only LHCBM1 is also involved in singlet oxygen scavenging. These results suggest that different LHCBM components have well defined, non-redundant functions despite their high homology, implying that engineering of LHCBM proteins can be an effective strategy for manipulating the light harvesting system of Chlamydomonas reinhardtii
Elucidation of the beta-carotene hydroxylation pathway in Arabidopsis thaliana reveals a fundamental role of epoxixanthophylls in photoprotection.
No full textThe first dedicated step in plant xanthophyll biosynthesis is carotenoid hydroxylation. In Arabidopsis thaliana, this reaction is performed by both heme (LUT1 and LUT5) and non-heme (CHY1 and CHY2) hydroxylases. No mutant completely abolishing α- or β-carotene hydroxylation has been described to date. We constructed double and triple mutant combinations in CHY1, CHY2, LUT1, LUT5 and LUT2 (lycopene epsilon-cyclase). In chy1chy2lut2, 80% of leaf carotenoids is represented by β-carotene. In chy1chy2lut5, β-carotene hydroxylation is completely abolished, while hydroxylation of the β-ring of α-carotene is still observed. The data are consistent with a role of LUT5 in β-ring hydroxylation, and with the existence of an additional hydroxylase, acting on the β-ring of α-, but not β-carotene
The effect of zeaxanthin as the only xanthophyll on the structure and function of the photosynthetic apparatus in Arabidopsis thaliana.
No full textIn green plants, the xanthophyll carotenoid zeaxanthin is synthesized transiently under conditions of excess light energy and participates in photoprotection. In the Arabidopsis lut2 npq2 double mutant, all xanthophylls were replaced constitutively by zeaxanthin, the only xanthophyll whose synthesis was not impaired. The relative proportions of the different chlorophyll antenna proteins were strongly affected with respect to the wild-type strain. The major antenna, LHCII, did not form trimers, and its abundance was strongly reduced as was CP26, albeit to a lesser extent. In contrast, CP29, CP24, LHCI proteins, and the PSI and PSII core complexes did not undergo major changes. PSII-LHCII supercomplexes were not detectable while the PSI-LHCI supercomplex remained unaffected. The effect of zeaxanthin accumulation on the stability of the different Lhc proteins was uneven: the LHCII proteins from lut2 npq2 had a lower melting temperature as compared with the wild-type complex while LHCI showed increased resistance to heat denaturation. Consistent with the loss of LHCII, light-state 1 to state 2 transitions were suppressed, the photochemical efficiency in limiting light was reduced and photosynthesis was saturated at higher light intensities in lut2 npq2 leaves, resulting in a photosynthetic phenotype resembling that of high light-acclimated leaves. Zeaxanthin functioned in vivo as a light-harvesting accessory pigment in lut2 npq2 chlorophyll antennae. As a whole, the in vivo data are consistent with the results obtained by using recombinant Lhc proteins reconstituted in vitro with purified zeaxanthin. While PSII photoinhibition was similar in wild type and lut2 npq2 exposed to high light at low temperature, the double mutant was much more resistant to photooxidative stress and lipid peroxidation than the wild type. The latter observation is consistent with an antioxidant and lipid protective role of zeaxanthin in viv
Different roles of alpha- and beta-branch xanthophylls inphotosystem assembly and photoprotection
No full textXanthophylls (oxygenated carotenoids) are essential components of the plant photosynthetic apparatus, where they act in photosystem assembly, light harvesting and photoprotection. Nevertheless, the specific function of individual xanthophyll species awaits complete elucidation. In this work we analyze the photosynthetic phenotypes of two newly isolated Arabidopsis mutants in carotenoid biosynthesis containing exclusively alpha-branch (chy1chy2lut5) or beta-branch (chy1chy2lut2) xanthophylls. Both mutants show complete lack of qE, the rapidly reversible component of non-photochemical quenching, and high levels of photoinhibition and lipid peroxidation under photooxidative stress. Both mutants are much more photosensitive than npq1lut2, which contains high levels of viola- and neoxanthin and an higher stoichiometry of light-harvesting proteins with respect to photosystem II core complexes, suggesting that the content in light-harvesting complexes plays an important role in photoprotection. In addition, chy1chy2lut5, which has lutein as the only xanthophyll, shows unprecedented photosensitivity even in low light conditions, reduced electron transport rate, enhanced photobleaching of isolated LHCII complexes and a selective loss of CP26 with respect to chy1chy2lut2, highlighting a specific role of beta-branch xanthophylls in photoprotection and in qE mechanism. The stronger photosystem II photoinhibition of both mutants correlates with the higher rate of singlet oxygen production from thylakoids and isolated light-harvesting complexes, while carotenoid composition of photosystem II core complex was ininfluential. In-depth analysis of the mutant phenotypes suggests that alpha-branch (lutein) and beta-branch (zeaxanthin, violaxanthin, neoxanthin) xanthophylls have distinct and complementary roles in antenna protein assembly and in the mechanisms of photoprotection

No full textAlthough small, the village of Sant'Antonio Rocchetta has a long history documented as a part of the territories of these political transformations, from the Middle Ages to the dilution of the Kingdom of Naples. Evolution itself of its place names - from the ancient Rocca Antimo, around which it was developed, the original urban core, in Rocchetta S. Antonio - you can re-read the history of the country at least since at least the eleventh century.
From the early years of the sixteenth century this story is closely linked to the presence of the Castle, built by Ladislaus II of Aquino in 1507.
It can not say that The Castle Aquinas is an unknown fortification; its particular shape planimetric with a triangular base with three bastions of “almond shape” or, if you will, to “bec d'éperon” (a spur beak) - as the origin of form is due to the French castles of the XI-XII century - has always struck the military architecture scholars, and particularly for its formal similarity with the fortifications of the greatest architect and military writer of the Renaissance in the second half of the fifteenth century, that is the Sienese architect Francesco di Giorgio Martini.
The importance of the architect, also commissioned by the major short and noble age - and especially for us by the Aragonese court of Naples - is witnessed by the operating result which had its original and updated works obsidional to new posts to the benchmarks with the technological improvement of firearms and the use of gunpowder, more devastating and feared. A retinue of followers architects and military engineers engaged in the fortification of the Kingdom under the constant threat of the Muslim enemy. Among these, among which we remember especially the florentine Antonio Marchesi from Settignano, must lie the author or at least the implementer of Castello d'Aquino on the model pioneered and popularized by Francesco di Giorgio
