Texto completo da fonteResumo:
This article addresses the derivational relationship between attributive (nominal) and predicative (verbal) possessives marked by the poss sign in American Sign Language. Though traditionally classified as a possessive pronoun, a collection of morphological, syntactic, and semantic patterns is presented here as evidence that poss instead displays the distributional characteristics of a verbal predicate in the language. Classifying poss as a verbal predicate of possession explains its presence in predicative possessives and allows its attributive use to be derived from this underlying verbal structure as an instance of a prenominal reduced relative clause modifier. These base structures and their interaction with other components of the predicative and attributive domains explain the documented properties of attributive and predicative poss possessives, including, crucially, the sometimes divergent behaviors of these two possessive constructions.

Texto completo da fonteResumo:
The goal of this article is to consider special properties which characterize the usage of partitive case in simple (non-possessive) declension in the language of the Yakut folk heroic epos olonkho. The relevance of this research is supported by the less studied status of partitive case as one of the most infrequent ones compared to other cases in the Yakut language as well as by the lack of theoretical research devoted to the usage of partitive case in the epic texts of olonkho. The following methods were used: descriptive, comparative, structural-semantic as well as the method of continuous sampling. Leipzig glossing rules were used in the article. The collected material contains examples from the following olonkho: “Nurgun the Strong” (“Nyurgun Bege”), “Ker Buuraj bogatyr” (“Kör Buuraj bukhatyyr”), “Tough Warrior woman” (“Kyydaannaakh Kyys Bukhatyyr”), “Ala-Bulkun”, “Kyys Debiliye”, “Olonkhos of Moma” (“Muoma olonkholoro”), “Myuljyu the Strong with unstumbling joints” (“Byudyuryujbet syukһyekhteekh Myulgyu Bege”), “Hero Eles with a bear-black horse” (“Eһe Khara attaakh Eles Bootur”), “Nyurgun Bootur the Swift” (“Julurujar Nyurgun Bootur”), “Lord Jagaryma” (“Tojon Jagaryma”), “Kyun Erili”, “Obstinate Kulun Kullustuur” (“Kuruubaj khaannaakh Kulun Kullustuur”), “Kyun Tegierime”, “Great Daaryn bogatyr” (“Uluu Daaryn bukhatyyr”), “Warrior woman Jyrybyna Jyrylyatta” (“Jyrybyna Jyrylyatta kyys bukhatyyr)”. Partitive case is considered to be one of the lesser used cases, due to the presence of a number of restrictions on its occurrence. If these conditions are met, then the usage of partitive case becomes possible, but not obligatory, since accusative or ablative cases might be used just as well. With the help of the data gathered using the method of continuous sampling from fifteen specimens of olonkho, it is demonstrated that nouns in the simple (non-possessive) form of the partitive case can act as a direct object with a variety of verbal forms. It has been shown that partitive case occurs in both paradigms of the imperative mood in all person-number combinations except third person. It is also employed with various voice and aspectual forms of the verbs, with the imperative particle kulu and with the emphatic-diminutive imperative. The results of the study reveal the hidden potential and the possibilities for more extensive usage of partitive case.

Dalmi, Gréte. "The status of the oblique possessor in BE-possessives: Evidence from Russian and Hungarian". Zeitschrift für Slawistik 66, n.º 4 (1 de novembro de 2021): 634–62. http://dx.doi.org/10.1515/slaw-2021-0029.
Texto completo da fonteResumo:
Summary This comparative syntactic study claims that the possessor of Russian and Hungarian BE-possessives neither originates nor lands in [Spec,VoiceP], the designated structural position of external arguments since Kratzer (1996). Possessive sentences universally describe a state with two eventuality participants, the possessor and the possessee (Stassen 2009). BE-possessives are built on dyadic-unaccusative existential BE. Neither of its two eventuality participants passes the agent/cause tests provided by Alexiadou, Anagnostopoulou & Schäfer (2015). It is claimed here that possessive BE-sentences in Russian and Hungarian pattern with the piacere-subclass of psych-predicates, inasmuch as the possessor bears the oblique case and the theme appears in the nominative in them. In the cartographic model, the oblique experiencer of the piacere-type of psych-predicates targets a position higher than canonical, agent/cause subjects do (see Cardinaletti 1997, 2004; Rizzi 1997, 2004 for Italian). This paves the way for oblique possessors and non-canonical subjects to appear in positions left-adjacent to the designated position for canonical, nominative subjects (see Cardinaletti 1997, 2004 for Italian; Benedicto 1995; Livitz 2006, 2012 for Russian; Dalmi 2000, 2005 for Hungarian). Possessive BE-predicates in Russian and Hungarian share a number of syntactic and semantic properties with existential BE (see Partee & Borschev 2008 for Russian and Szabolcsi 1992, 1994 for Hungarian). Nonetheless, BE-possessives and BE-existentials differ in the two languages in their clausal architecture, due to the fact that EPP is fulfilled in different ways in them.

Texto completo da fonteResumo:
In lieu of an abstract, here is a brief excerpt:This paper argues that crosslinguistic variation in the forms of clausal possessive predication arises to a large extent from the NON-VERBAL nature of possessive predication. As evidence, I demonstrate that possessive predication across languages shows all the variation possible for non-verbal predication in general. I show the non-verbal approach not only accounts for previously observed major strategies in pos-sessive predication, for both INDEFINITE and DEFINITE possessive predication (also known respectively as HAVE and BELONG possessives), it also predicts the availability of “minor”, less-frequently observed encoding strategies.

Texto completo da fonteResumo:
AbstractThis study presents the first investigation of the development of possessive constructions in Northern East Cree, a polysynthetic language indigenous to Canada. It examines transcripts from naturalistic recording sessions involving one adult and one child, from age 2;01.12 to 3;08.24. Findings reveal that, despite the frequency of possessive inflection in child-directed speech, the child overwhelmingly produces a possessive construction that circumvents this morphology. This construction, named here the equational possessive strategy (EPS), is largely undescribed in existing literature but is the primary mechanism for the child to express possession. These findings have potential implications for the cross-linguistic acquisition of possessive morphology and the connections between child-directed speech and child language production.

Texto completo da fonteResumo:
The noun city is an actively epithetized image of Ukrainian poetry of the twentieth century. Around it are definitions with direct, descriptive meaning (autological) and with figurative, figurative-evaluative (metalogical). Autologous definitions include characteristics of size (large, giant, small), age (new, old, ancient, ancient, ancient, eternal, young), location relative to the administrative center (central, provincial), distance from the location of the lyrical hero. close), time (morning, evening, night). Also traditional for the Ukrainian poetic language is the use of the nomination city and specific names of cities with epithets beautiful, abandoned, unfamiliar, with possessive pronouns my, our. In many epithets to the image of the city material-subject plan is inferior to the emotional-expressive, metaphorical, associative-figurative word usage prevails over the direct, nominative. The semantic structure of such constructions is dominated by seven ‘visual perception’, ‘audio perception’, ‘psychological perception’, ‘historical assessment’. Among the artistic definitions with the sema ‘visual perception’ the most branched color-epithet series – white, yellow, green, blue, gray, gray, black, gold. Carriers with a color sign (golden-topped, silver-haired, white-winged) are carriers of complicated semantics and value. The aesthetics of definitions with the dominant family ‘psychological perception’ (suffering, torn, exhausted, tired, tragic, etc.) is determined by their imagery and emotional coloring. Anthropomorphic epithets transfer to the image of the city signs of psycho-emotional states (fatigue, suffering), character traits (pride, tenderness, kindness, insecurity), morality or immorality (innocence, sinfulness), as well as external portrait traits or signs of human physical condition. Characteristic epithet microparadigms develop realities that structure the city space, specify its social and cultural infrastructure. In general, epithetization reflects both realistic and figurative-symbolic, philosophical-generalized meaning of the image of the city. It is both a geographical object and an aestheticized artistic space in which lyrical heroes self-identify. Such a complex nature of the image opens up prospects for its broad interpretation.

Texto completo da fonteResumo:
AbstractThis paper deals with the linguistic means used to express predicative possession in the languages of the Circum-Baltic area. The domain of possession is considered here as a prototypically organized domain, where the prototype is the notion of ownership. It is shown that most languages of the area do not provide evidence of splits in their possession systems: rather, they extend the scope of use of their ownership constructions to include all other non-prototypical possessive notions. The linguistic expression of notions that belong to domains neighboring possession, namely experience, location and attribution, is also analyzed. The results show that these notions are rarely coded by means of possessive constructions: exceptions are explained by invoking semantic causes as well as language contact. A comparison of the functions fulfilled by “have”-verbs in the Indo-European languages of the area and by adessive constructions in the Finnic languages is provided, too, and their different scopes of use are explained with reference to their diachronic development and to processes of areal convergence.

Texto completo da fonteResumo:
Despite its highly subjectivised title, Laura – Otto Preminger's dazzling 1944 noir classic – is, according to this article, a film not so much about persons as things. And what spectacularly beautiful things Laura proffers: exquisite objets d'art, chic fashion, striking design. All of which points to a certain psychic condition that underpins Laura: namely, fetishism. Of course, the fetish nonpareil in the film is Laura herself; she is the not so ‘obscure object of desire’ for all and sundry, possessing everyone in the film, and, in turn, being treated by those possessed, as a possession herself. Though the nature of these sorts of possessory regimes differs dramatically, being contingent upon the psychic profile of the possessor: love interest Shelby Carpenter, police detective Mark McPherson and wealthy mentor, Waldo Lydecker. This article will explore Laura's competing possessory regimes, utilising psychoanalytic concepts such as hysteria, repetition compulsion and the death drive, as well as fetishism and sado-masochism to unpack this vivid filmic representation of the ‘Law of Desire’ as a desire for what is, here, law's objet petit a – feminine sexuality itself.

Texto completo da fonteResumo:
Arma virumque cano Virgil sang, or professed to sing, at the start of his epic, and one may reformulate the import of his programmatic words to fit a new context. Obtaining weapons he can call his own is very often a key moment near the start of the career of a folk-tale hero. And very often it is the hero's mother who equips him with them. Paradoxically, this truth may be confirmed, e contrario, by reference to the Welsh story of Lleu Llaw Gyffes from the Mabinogion, for, in that narrative, the hero's mother Aranhry seeks to thwart at its inception the career of her son – whom she had exposed, since his very existence causes her so much embarrassment – by placing a Destiny or interdiction upon him: he will never bear arms unless and until she herself bestows them. The ban is circumvented by a cunning ruse: the magician Gwydion disguises her son and himself as peripatetic bards, in which capacity they are entertained in Aranhry's castle. When Gwydion conjures up a phantom army and fleet to besiege the citadel, the alarmed Aranhry is all too ready to bestow weapon and armour on the younger of her two guests – only to find the army vanished and her own son in possession of the arms she had sworn he would not bear.

Texto completo da fonteResumo:
Telepathy and joint consciousness have long been a feature in SF stories. Here, we sample several visions and see how cognitive theory and brain-brain communication technology relate to the scope and plausibility of these fictional portrayals. One dimension of variation here is between possession and mind manipulation on the one hand, and an equitable and beneficent sharing of consciousness on the other. The former is exemplified in Aldiss’s power-hungry fungus, the latter in Sturgeon’s vision of a superhuman Gestalt where the whole is more than the sum of its parts, and the moral conscience is the capstone.

Texto completo da fonteResumo:
This study examines the influence of task repetition (TR) and pretask focus on form instruction (FFI) on written collaborative production. Eighty-five low-proficiency EFL children carried out a dictogloss task twice: one targeting the 3rd person singular present “‑s”, and the other aiming at the possessive determiners “his/her”. Participants were divided into three different conditions: individual, collaborative, and pretask FFI + collaborative. Their written output was analyzed for complexity and accuracy, and overall text quality was gauged with an analytic rubric. The results did not reveal an advantage for the collaborative groups over the individuals. However, TR and collaboration increased grammatical accuracy while pretask FFI appeared to foster more accurate use of the target forms. Pedagogical and research implications are discussed.

Texto completo da fonteResumo:
Abstract This chapter explores biography as a complex of various genres that challenge and extend autobiography and claim the social intelligibility of another’s life. Contributing to authorized histories and secret histories, biography solidified a historiography that centred on the individual and connected psychology and politics. Romantic print culture consolidated possessive individualism and its literary figure, the realistic hero, and biography helped establish the realistic analogue of fiction, the celebrity. The inaugural Public Characters (1798) declared biography ‘the most fascinating and instructive species of literary composition’; such comments, whether earnest or flippant, bolstered the production of Boswellian biographies, such as Thomas Moore’s Life of Byron, a reconstruction of the Romantic hero of self-consciously autobiographical living. Similarly, Walter Scott’s, William Hazlitt’s, and William Henry Ireland’s competing multi-volume lives of Napoleon, each stemming from distinct political and literary sensibilities, all seek to define European modernity through biography.

Texto completo da fonteResumo:
This chapter discusses traditional small-scale multilingualism in Southern New Guinea (SNG), in connection with the expression of possession in one of the languages spoken here: Idi. SNG is a high diversity region with many languages and families attested, and individuals tend to be highly multilingual. Throughout the area, patterns of language contact are grounded in established cultural practices of intermarriage. A system of symmetrical sister exchange produces many linguistically exogamous marriages. Children from such marriages usually acquire both their father’s (their primary or “emblematic” language of identification) and their mother’s language. Other languages are picked up from other family members and as people travel within the region or further afield for education, work or church activities. Practices of receptive multilingualism are widely reported. Idi has two types of possessive pronoun, termed “close” and “distant” possessive. Which type of possessive is used appears to be driven partly by semantics, based on alienability, and partly by pragmatics. The chapter looks specifically at how Idi speakers use possessives in the context of discussing the languages they speak. The linguistic landscape of the region is reflected in Idi, in the ways that possessive forms are used to refer to the different languages speakers acquire during their lifetime.

Texto completo da fonteResumo:
Beginning in the 1980s, inequality of incomes in the metropolitan core began to increase. This great divergence was most pronounced in the Anglophone world—Great Britain, the United States, Canada, Australia, and New Zealand. This divergence suggests that there is nothing inherent—structurally determinative—in capitalism as it operates in the rich metropole that brings about this unwelcome trend. Rather, inequality is willful—intended. Ironically, inequality is enabled by the prevalence of possessive individualism that reveals the acquisitive individualist to be the source of his or her own unwanted economic marginalization. The individualist’s embrace of a livelihood strategy based on the celebration of rights and the illusion of freedom—being free to choose—has placed him or her at the mercy of the capitalist firm equally committed to possessive individualism. The capitalist firm must be transformed into a public trust. However, this will not be sufficient. Improved livelihoods will also require that the possessive individual be reimagined.

We here explore the gradual emasculation of the household as the basic unit of provisioning during the four evolutionary phases of capitalism. This economic history reveals a gradual redefinition of the purpose of the household from the center of entrepreneurial initiative to a besieged and insecure provider of inconvenient and unwanted labor to managerial capitalism whose central imperative is to reduce labor costs in the service of greater net returns to owners of capital. This evolutionary pathway will reveal the household to be an increasingly precarious and politically vexing participant in global capitalism.

Texto completo da fonteResumo:
Escape from possessive individualism requires that the terms of engagement between households and firms be rebalanced. Rarely is the firm seen as the essential component in the economic well-being of households. And when it is seen in this light, contestation over wages and work conditions arises. The post-revolutionary regimes in China and the Soviet Union then tried to situate that obligation on the government. We know how that turned out. A better solution—economically and politically—is to bring capitalist firms into a joint obligation with the government in this essential task. The persistence of union-busting, desultory pay and fringe benefits, layoffs, plant closings, automation, and out-sourced jobs to foreign countries ought to remind politicians—and capitalists—that radical solutions are always available if hope is too long delayed. We now concentrate on the difficult realm of ideas. For here lurks the greatest barrier to necessary institutional change—defective imagination.

Texto completo da fonteResumo:
Spirit possession is what anthropologists call a common “idiom of distress” in India. That is, anthropologists observe that spirit possession is a way of behaving that signals emotional trouble. Spirit possession in India often begins with intense distress to the afflicted. However, through negotiation and attention to its desires, possessing spirits may be transformed from malevolent to beneficent. Sumita is a devotee and long-term resident of the Balaji temple in Rajasthan, India. After her marriage, demands for dowry, domestic violence, and Sumita’s growing awareness of the destructive spirits living in the walls of her husband’s home, her in-laws expel her from their home. After numerous stays in publicly-funded psychiatric facilities, she is brought by her father to the temple of Balaji, where she begins to hear the voice of the deity. Sumita manages to eke out a marginal existence by passing on the divine revelations of Balaji to worshipers at the shrine. In this way, her spirit possession may participate in the construction of a valued social identity in which voices and visions are signs of the divine and not solely associated with a permanent, crippling illness.

Texto completo da fonteResumo:
Abstract These have already been mentioned in several places; it will be useful to gather the facts together here. ‘Possessive pronouns’ are ordinary adjectives formed from the stems of the personal pronouns by the addition of thematic inflection (-o-/-eH2-) or with the contrastive suffix “-tero-/-tereH2- (355). The contrastive function of such adjectives is obvious, but the reason for the prominence of the con trastive affix in the plural is not.1 1. G i:µ,or;, i:µ,for; have a mixed ancestry, continuing the old gen. ‘meme; the enclitic possessives attested as such in Hitt. (-mi-if nom., -mi-in, -ma-an acc., and so on); and yet other ingredients. See 367.2. L meus is presumably from ‘meyos elaborated from the enclitic gen.dat., but the only unambiguous attestations of such point to ‘moy, not ‘mey: OCS moj[ ‘my’, G µ,oi dat. Contamination from acc. ml with help from possessive adj. ‘tewos, ‘sewos is likelier than a special e-grade etymon.

Phase conjugated light waves reverse phase distortions in media with negligible absorption or for paraxial beam propagation [1].

We show theoretically that for multiplexed signals, cross-talk-free phase-conjugation is obtained only for negligible spatial-frequency dispersion and a phase-conjugated reference or pump wave, and we present supporting experimental results.

There has been rapid experimental progress in the shaping of single ultrashort light pulses into sequences of pulses of specified separation, duration, and relative optical phase 1,2a. Phase-controlled pulse sequences have found a number of applications to molecular systems 2b,c, and several more have been the subject of theoretical calculations. The salient feature of electronically resonant phase-controlled pulse trains is their ability to generate superpositions of multiple time-dependent contributions to the nuclear wave function in a given electronic state having well-defined relative quantum phases. Here we describe two uses to which that feature might fruitfully be put in preparing and probing time-dependent nuclear wave functions in the ground electronic state possessing chemically or spectroscopically useful properties.

In the real world, we use our innate manual dexterity to create and manipulate 3D objects. Conventional virtual design tools largely neglect this skill by imposing non-intuitive 2D control mechanisms for interacting with 3D design models. Their usage is thus cumbersome, time consuming and requires training. We propose a novel design paradigm that combines users’ manual dexterity with the physical affordances of non-instrumented and ordinary objects to support virtual 3D design constructions. We demonstrate this paradigm through Proto-TAI, a quick prototyping application where 2D shapes are assembled into 3D representations of ideated design concepts. Here, users can create 2D shapes in a pen-based sketch medium and use expressive handheld movements of a planar proxy to configure the shapes in 3D space. The proxy provides a metaphorical means for possessing and controlling the shapes. Here, a depth sensor and computer vision algorithms track the proxy’s spatial movement. The 3D design prototype constructed in our system can be fabricated using a laser cutter and physically assembled on-the-fly. Our system has vast implications in many design and assembly contexts, and we demonstrate its usability and efficacy through user studies and evaluations.

Abstract The nonlinear dynamics of a circular spinning disc parametrically excited by noise of small intensity is investigated. The governing PDEs are reduced using a Galerkin reduction procedure to a two-DOF system of ODEs which, govern the transverse motion of the disc. The dynamics is simplified by exploiting the S1 invariance of the equations of motion of the reduced system and further, reduced by performing stochastic averaging. The resulting one-dimensional Markov diffusive process is studied in detail. The stationary probability density distribution is obtained by solving the Fokker-Planck equation along with the appropriate boundary conditions. The boundary behaviour is studied using an asymptotic approach. Some aspects of dynamical and phenomenological bifurcations of the stationary solution are also investigated. The scheme of things presented here can be applied in principle to a four-dimensional Hamiltonian system possessing one integral of motion in addition to the hamiltonian and having one fixed point.

In recent years there has been considerable interest in the development of electronic money schemes. Electronic money has the potential to take over from cash as the primary means of making small-value payments and could make such transactions easier and cheaper for both consumers and merchants. Electronic money is a record of the funds or "value" available to a consumer stored on an electronic device in his or her possession, either on a prepaid card or on a personal computer for use over a computer network such as the Internet. This paper argues that e-money, as a network good, could become an important form of currency in the future. Such a development would influence the effectiveness and implementation of monetary policy. If an increased use of e-money substantially limits demand for central bank reserves, it would require changes in the operational target of the central bank and a closer coordination of monetary and fiscal policies.

The nonlinear features of the steady-state periodic response of hysteretic oscillators are investigated. Frequency-response curves of base-excited single-degree-of-freedom (SDOF) systems possessing different hysteretic restoring forces are numerically obtained employing a continuation procedure based on the Jacobian of the Poincaré map. The memory-dependent restoring forces are expressed as a direct summation of linear and cubic elastic components and a hysteretic part described by a modified version of the Bouc-Wen law. The resulting force-displacement curves feature a pinching around the origin. Depending on the hysteresis material parameters (which regulate the shapes of the hysteresis loops), the oscillator exhibits hardening, softening and softening-hardening behaviors in which the switching from softening to hardening takes place above certain base excitation amplitudes. A comprehensive analysis in the parameters space is performed to identify the thresholds of these different behaviors. The restoring force features here considered have been experimentally obtained by means of an original rheological device comprising assemblies of steel and shape memory wire ropes. This study is carried out also with the aim of designing the restoring forces which give rise to dynamical behaviors useful for a variety of applications.

During situations of high incidence, high curvature of aero-engine intake lips can locally accelerate flow to supersonic speeds, producing undesirable shock wave boundary layer interactions (SWBLIs). The present work describes simulations of a novel experimental model resembling a lower intake lip at incidence. RANS, LES and hybrid RANS-LES are carried out at two angles of attack, α = 23° and α = 25°, with α = 25° possessing a high degree of shock oscillation. Modifications to the Spalart-Allmaras (SA) RANS turbulence model are proposed to account for re-laminarisation and curvature. These provide an improvement in prediction compared standard SA model. However, RANS models fail to reproduce post shock interaction flow, giving incorrect shape of the flow distortion. LES and hybrid RANS-LES perform well here, with downstream flow distortion in very good agreement with experimental measurements. LES and hybrid RANS-LES also capture the time averaged smearing of the shock which RANS cannot. However, low frequency shock oscillations in the α = 25° case are costly for LES, requiring long simulation time to obtain time averaged flow statistics. Hybrid RANS-LES offers a significant saving in computational cost, costing approximately 20% of LES.

Abstract. Knowing the large strain flow curve is essential for many simulation processes in the sheet metal forming technology. A prominent example is the clinching, when the strains are one magnitude higher than in tension, but a simple deep-drawing process could also lead to appropriately large strains. To obtain the flow stress - plastic strain curves beyond the range of tension, several processes are known. In the most multi-axial cases, a conversion factor based on the work equivalence is usually applied on the measurement results to obtain the equivalent quantities. However, at compressive experiments, the friction and the geometrical issues may distort the curve shape even further, hiding the real material behavior. In this study we investigate the effect of the friction determination method and the value of the friction coefficient on the curve shape. Pressure dependent and constant friction coefficients were inversely specified by disk compression tests and related finite element modeling. In possession of the friction values, the conversions of the physically measured compressive stress to equivalent flow stress during disk and stack compression tests with different height-diameter ratios are discussed here.
