title:  Content Teachers’ Perceptions Towards EMI in Chinese Universities

Publisher: name: Roma TrE-Press

description: Negli ultimi anni, molte università di tutto il mondo hanno man mano adottato l'uso della lingua inglese come lingua franca accademica per l'insegnamento di varie discipline. L'inglese come mezzo di insegnamento (EMI) ha permesso agli studenti di proseguire gli studi superiori al di fuori dei propri paesi d'origine. A partire dal 2001, EMI ha acquistato sempre più importanza presso un numero crescente di università cinesi. Anche se il numero di studi pubblicati su questo tema è aumentato, molte di questi lavori sono di carattere teorico e si concentrano sulle esperienze degli autori. In ogni caso, c'è una scarsa ricerca empirica su come gli insegnanti di varie discipline percepiscano sia EMI, sia l'uso della lingua inglese nelle università cinesi. Il presente studio prende in esame le opinioni dei docenti di dieci università cinesi circa l'uso della lingua inglese nell'insegnamento delle loro materie e si occupa di ciò che gli insegnanti pensano dell'inglese. L'analisi dell'impatto e degli orientamenti riguardanti EMI in Cina è parte del mio progetto di ricerca di dottorato. I docenti selezionati insegnano una vasta gamma di discipline. I dati consistono nelle opinioni degli insegnanti, ottenute per mezzo di questionari e interviste. I risultati preliminari indicano che la maggioranza dei partecipanti guarda ad EMI favorevolmente, ma allo stesso tempo manifesta preoccupazione per la difficoltà di adattarlo all'insegnamento. Diversi intervistati hanno riferito che sia l'inglese, sia il cinese sono utilizzati in classe. I primi risultati sono analizzati in relazione al futuro sviluppo in Cina di programmi di EMI e di ELT.

description: 1. We reported previously that bisphosphate derivatives of adenosine are antagonists of the P2Y(1) receptor and that modification of the ribose in these analogues is tolerated in the P2Y(1) receptor binding pharmacophore. 2. Here we delineate the pharmacological activity of one such non-nucleotide molecule, 2-chloro N(6)-methyl-(N)-methanocarba-2'-deoxyadenosine-3',5'-bisphosphate (MRS2279), in which the ribose is replaced by a cyclopentane ring constrained in the (N)-conformation by a cyclopropane moiety. 3. MRS2279 antagonized 2MeSADP-stimulated inositol phosphate formation in turkey erythrocyte membranes with competitive kinetics (pK(B)=7.75). High affinity competitive antagonism by MRS2279 was also observed at the human P2Y(1) receptor (pK(B)=8.10) stably expressed in 1321N1 human astrocytoma cells. Antagonism was specific for the P2Y(1) receptor since MRS2279 had no effect on activation of the human P2Y(2), P2Y(4), P2Y(6), or P2Y(11) receptors by their cognate agonists. 4. MRS2279 also did not block the capacity of ADP to act through the Gi/adenylyl cyclase linked P2Y receptor of platelets to inhibit cyclic AMP accumulation. 5. In contrast, the P2Y(1) receptor is known to be obligatory in the process of ADP-induced platelet aggregation, and MRS2279 competitively inhibited ADP-promoted platelet aggregation with an apparent affinity (pK(B)=8.05) similar to that observed at the human P2Y(1) receptor heterologously expressed in 1321N1 cells. 6. Taken together these results illustrate selective high affinity antagonism of the P2Y(1) receptor by a non-nucleotide molecule that should prove useful for pharmacological delineation of this receptor in various tissues.

description: The Casimir interaction in a stack of equally spaced infinitely thin layers is investigated within the zero-frequency mode summation method. The response properties are considered to be described by a constant conductivity or by a Drude-Lorentz model with a finite set of oscillators consistent with the optical characteristics for graphite. It is found that the asymptotic distance dependence is affected significantly by the specific response. While the energy is $\sim 1/d^3$ for the constant conductivity model, the energy exhibits fractional dependence $\sim 1/d^{5/2}$ for the Drude-Lorentz description. The Casimir force on a plane is also strongly dependent upon the particular plane location in the stack. Furthermore, the calculated Casimir energy within the Drude-Lorentz model yields results in good agreement with measured cohesion energy in graphite.

description: La crisi economica ha favorito politiche di restrizione dei bilanci degli Stati. Queste vengono realizzate anche attraverso l?intervento sui beni pubblici, sia con la ricerca di una maggiore efficienza nella gestione, sia tramite pratiche di dismissione e vendita. Questa linea di intervento � per� riduttiva, perch� si limita a un approccio di tipo ?quantitativo?, che rischia di avere come conseguenza la diminuzione della capacit� delle amministrazioni pubbliche di dare risposte adeguate ai bisogni dei cittadini. Occorre, quindi, andare alla ricerca di paradigmi e soluzioni alternative, capaci di assicurare al contempo, da un lato, innovazione e crescita economica, dall?altro, coesione sociale e sicurezza. In questa prospettiva, i ?beni comuni? assumono particolare importanza. I saggi raccolti nel presente volume ne considerano le caratteristiche e le potenzialit�. Innanzitutto, come risorse ?nuove? a cui attingere per garantire bisogni altrimenti non pi� soddisfabili a causa della penuria di risorse di tipo tradizionale. Ma anche come mezzi attraverso cui � possibile attivare, nel momento stesso della loro cura, delle dinamiche relazionali tra pubbliche amministrazioni e soggetti privati, le quali possono fungere da catalizzatori di nuove energie e diventare quindi esse stesse una risorsa, in quanto idonee a creare del ?valore sociale aggiunto? con il loro svolgimento.

description: We establish the factorization formula for scalar Glueball production through radiative decays of vector states of heavy quarkonia, e.g. $J/ψ$, $ψ(2S)$ and $Υ(nS)$, where the Glueball mass is much less than the parent heavy quarkonium mass. The factorization is demonstrated explicitly at one-loop level through the next-to-leading order (NLO) corrections to the hard kernel, the non-relativistic QCD (NRQCD) long-distance matrix element (LDMEs) of the heavy quarkonium, and the light-cone distribution amplitude (LCDA) of scalar Glueball. The factorization provides a comprehensive theoretical approach to investigate Glueball production in the radiative decays of vector states of heavy quarkonia and to determine the physic nature of Glueball. We discuss the scale evolution equation of LCDA for scalar Glueball. In the end, we extract the value of the decay constant of Scalar Glueball from Lattice QCD calculation and analyze the mixing effect among $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$.

Orbital selectivity and emergent superconducting state from quasi-degenerate $s-$ and $d-$wave pairing channels in iron-based superconductors

description: A major puzzle about the nature of the iron-based superconductivity appears in the case of the alkaline iron selenides. Compared to the iron pnictides, these systems have only electron Fermi pockets (i.e. no hole Fermi pockets) but comparable superconducting transition temperatures. The challenge lies in reconciling the two basic experimental features of their superconducting state: a node-less gap and the existence of a resonance in the spin excitation spectrum. We propose a mechanism based on reconstructing two quasi-degenerate pairing states, one in an $s$-wave $A_{1g}$ channel that is fully gapped, and the other in a $d$-wave $B_{1g}$ channel whose pairing function changes sign across the electron Fermi pockets at the Brillouin-zone boundary. The resulting intermediate pairing state, which we call an orbital-selective $s \times τ_3$ state, incorporates both of the above two properties. When the leading spin-singlet pairing is in the $d_{xz}, d_{yz}$ orbital subspace, this state retains the $s$-wave form factor but has a $B_{1g}$ symmetry due to an internal $τ_3$ structure in the orbital space. Within a five-orbital $t-J_{1}-J_{2}$ model with orbital-selective exchange couplings, we show that the proposed pairing state is energetically competitive over a finite range of control parameters. We calculate the dynamical spin susceptibility in the orbital-selective $s \times τ_3$ superconducting state and show that a spin resonance arises and has the characteristics of observed by inelastic neutron experiments in the alkaline iron selenides. More generally, the formation of the orbital-selective $s \times τ_3$ state represents a novel means of relieving the quasi-degeneracy between $s-$ and $d-$wave pairing states, which is a hitherto unsuspected alternative to the conventional route of linearly superposing the two into a time-reversal symmetry breaking $s+id$ state.

description: 1 Available anticancer drugs do not seem to modify the prognosis of metastatic melanoma. Salicylate and acetyl salicylic acid (aspirin) were found to suppress growth in a number of transformed cells, that is, prostate and colon. Therefore, we studied the direct effects of aspirin on metastatic B16 melanoma cells. 2 Aspirin at a plasma-attainable and nontoxic level suppressed the proliferation of B16 cells. 3 Aspirin induced the activation of p38 and c-Jun N-terminal kinase (JNK) mitogen-activated protein kinases. 4 Inhibition of JNK, but not p38, decreased the suppressive effect of aspirin upon the proliferation of B16 cells. 5 The aspirin-induced reduction in B16 proliferation was cumulative over time. 6 Aspirin and the chemotherapeutic drug 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) induced B16 cell death synergistically. 7 In addition to the murine B16 cell line, the proliferation of SK-28 human melanoma cells was also suppressed by aspirin. 8 In conclusion, aspirin suppresses the proliferation of metastatic B16 cells in a JNK-dependent mechanism.

description: 1 Leukocyte production of reactive oxygen species (ROS) is an essential component of the antimicrobial armament mounted during host defense, but when released to the extracellular milieu ROS can also injure host tissues and provoke inflammation. Polyisoprenyl phosphates (PIPPs) are constituents of human leukocyte membranes that regulate pivotal intracellular enzymes, such as phospholipase D (PLD). We prepared new PIPP mimetics and studied their impact in vivo on leukocyte activation, including ROS generation, in acute inflammation. 2 In a stereospecific and concentration-dependent manner, the PIPP mimetics directly regulated Streptomyces chromofuscus phospholipase D (sPLD) action. The IC50for a (Z)-isomer of endogenous presqualene diphosphate (PSDP) was 100 nM. 3 Structure-activity relationships were also determined for PIPP mimetic inhibition of recombinant human PLDlb, a prominent isoform in human leukocytes. The PIPP mimetic rank order for PLDlb inhibition differed from sPLD, although the (Z)-PSDP isomer remained the most potent PIPP mimetic for inhibition of both enzymes. Truncation of PLDlb to its catalytic core uncovered potential regulatory roles for both PSDP's isoprenoid and diphosphate moieties. 4 The (Z)-PSDP isomer reduced ROS production by activated human leukocytes and decreased murine neutrophil accumulation (65.6%) and ROS production (38.5%) in vivo during zymosan A-initiated peritonitis. When administered intraperitoneally 2 h after zymosan A, the (Z)-PSDP isomer decreased in vivo neutrophil accumulation (72.5%) and ROS generation (74.4%) 6 h later in peritoneal exudates. 5 Together, these results provide new means to protect and control unchecked inflammatory responses that characterize many human diseases.

description: Analysis of the P2Y family of nucleotide-activated G-protein-coupled receptors has been compromised by the lack of selective high-affinity, high-specific-radioactivity radioligands. We have pursued quantification of the P2Y receptor through the development of a series of selective P2Y receptor antagonists.Recently, we synthesized 2-iodo--methyl-()-methanocarba-2′-deoxyadenosine 3′,5′-bisphosphate (MRS2500), a selective, competitive antagonist that exhibits a of 0.8 n in competition-binding assays with [H]MRS2279. A 3′-monophosphate precursor molecule, MRS2608, was radiolabeled at the 5′ position with P using polynucleotide kinase and [P]ATP to yield [P]MRS2500.[P]MRS2500 bound selectively to Sf9 insect cell membranes expressing the human P2Y receptor (Sf9-P2Y), but did not detectably bind membranes expressing other P2Y receptors. P2Y receptor binding to [P]MRS2500 was saturable with a of 1.2 n. Agonists and antagonists of the P2Y receptor inhibited [P]MRS2500 binding in Sf9-P2Y membranes with values in agreement with those observed in functional assays of the P2Y receptor.A high-affinity binding site for [P]MRS2500 (=0.33 n) was identified in rat brain, which exhibited the pharmacological selectivity of the P2Y receptor. Distribution of this binding site varied among rat tissues, with the highest amount of binding appearing in lung, liver, and brain. Among brain regions, distribution of the [P]MRS2500 binding site varied by six-fold, with the highest and lowest amounts of sites detected in cerebellum and cortex, respectively.Taken together, these data illustrate the synthesis and characterization of a novel P2Y receptor radioligand and its utility for examining P2Y receptor expression in native mammalian tissues.

Vacuum energy is non-positive for (2+1)-dimensional holographic CFTs

description: We consider a (2+1)-dimensional holographic CFT on a static spacetime with globally timelike Killing vector. Taking the spatial geometry to be closed but otherwise general we expect a non-trivial vacuum energy at zero temperature due to the Casimir effect. We assume a thermal state has an AdS/CFT dual description as a static smooth solution to gravity with a negative cosmological constant, which ends only on the conformal boundary or horizons. A bulk geometric argument then provides an upper bound on the ratio of CFT free energy to temperature. Considering the zero temperature limit of this bound implies the vacuum energy of the CFT is non-positive. Furthermore the vacuum energy must be negative unless the boundary metric is locally conformal to a product of time with a constant curvature space. We emphasise the argument does not require the zero temperature bulk geometry to be smooth, but only that singularities are `good' so are hidden by horizons at finite temperature.

description: Modelled on efficient algorithms for solving the conjugacy problem in hyperbolic groups, we define and study the permutation conjugacy length function. This function estimates the length of a short conjugator between words $u$ and $v$, up to taking cyclic permutations. This function might be bounded by a constant, even in the case when the standard conjugacy length function is unbounded. We give applications to the complexity of the conjugacy problem, estimating conjugacy growth rates, and languages. Our main result states that for a relatively hyperbolic group, the permutation conjugacy length function is bounded by the permutation conjugacy length function of the parabolic subgroups.

Year: 2018

description: The aim of this work is to analyze the complex world of smart, intelligent and active packaging in food industry and to highlight the regulatory challenges that technological innovation is posing in the European Food Law framework and in other legal systems of the world. The first chapter deals with an historical analysis of the evolution of food containers and then with an explanation of what food packaging means today, as a fundamental media of the relationship between products and consumers. The development of new materials and materials the lead to the concept of ?smart packaging?, a definition used in scientific literature for the first time in 1986, are also examined. The second chapter analyzes the legal aspects of smart food packaging. EU law didn?t allow the production and the introduction in the market of smart packaging solutions until Reg. (CE) n. 1935/2004, on materials coming into contact with food, and Reg (CE) n. 450/2009, establishing specific criterions for smart and active packaging. The European Community has adopted legislation inspired by the precautionary principle. The third chapter draw a comparison between the European legislation and the US, Japanese and Australian law, where the smart packaging industry appears to be rapidly evolving. The final part of this research focuses on smart RFID technology applied to food packaging. RFID requires particular labels that use radio frequencies, enabling containers to become active units of information that can interact with the system of production and distribution of foodstuff. RFID allows the traceable itinerary of single units of food and enable an instantaneous control of anomalies. The potential of this technology proves to be extremely promising to improve food safety and to enhance new ways for assessing the quality of food. At the same time this technology poses new risks for consumers? privacy and personal data protection.

description: This review discusses the challenges of chemotherapy for human African trypanosomiasis (HAT). The few drugs registered for use against the disease are unsatisfactory for a number of reasons. HAT has two stages. In stage 1 the parasites proliferate in the haemolymphatic system. In stage 2 they invade the central nervous system and brain provoking progressive neurological dysfunction leading to symptoms that include the disrupted sleep wake patterns that give HAT its more common name of sleeping sickness. Targeting drugs to the central nervous system offers many challenges. However, it is the cost of drug development for diseases like HAT, that afflict exclusively people of the world's poorest populations, that has been the principal barrier to new drug development and has led to them becoming neglected. Here we review drugs currently registered for HAT, and also discuss the few compounds progressing through clinical trials. Finally we report on new initiatives that might allow progress to be made in developing new and satisfactory drugs for this terrible disease.

description: The P2Y14 receptor is activated by UDP-sugars, most potently by UDP-glucose, but not by free nucleotides, suggesting that UDP-glucose is the cognate agonist for this receptor. However, evidence for regulated release of UDP-glucose is scarce. In the present study, the occurrence of receptor-promoted release of UDP-glucose was investigated, using 1321N1 human astrocytoma cells.

Biased signalling and allosteric machines: New vistas and challenges for drug discovery
Creators: name: Kenakin, Terry P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Seven transmembrane receptors (7TMRs) are nature's prototype allosteric proteins made to bind molecules at one location to subsequently change their shape to affect the binding of another molecule at another location. This paper attempts to describe the divergent 7TMR behaviours (i.e. third party allostery, receptor oligomerization, biased agonism) observed in pharmacology in terms of a homogeneous group of allosteric behaviours. By considering the bodies involved as a vector defined by a modulator, conduit and guest, these activities can all be described by a simple model of functional allostery made up of the Ehlert allosteric model and the Black/Leff operational model. It will be shown how this model yields parameters that can be used to characterize the activity of any ligand or protein producing effect through allosteric interaction with a 7TMR.
Constructing Food Citizenship: Theoretical Premises and Social Practices
Creators: name: Gómez-Benito, Cristóbal
name: Lozano, Carmen
Publisher: name: QuiEdit
Year: 2015
Subjects: food citizenship; political consumerism; food democracy

description: The reflection on food citizenship becomes pertinent if we take into account the importance of food and nourishment as constituting that which is social, its economic relevance, its globalized character, the fact that it is a highly regulated sector, and the important risks related to food. This context justifies, as well as conditions, the possibilities and difficulties of the emergence of a food citizenship. The framework establishes the expressive dimensions and the spheres of praxis of food citizenship and of the construction of the policies that facilitate the emergence and consolidation of this new space in which to exercise citizenship.

In this paper, we will propose a concept of food citizenship based on the general concept of citizenship and of its connection to other similar concepts from which it must be differentiated and with which it must be related. This concept is based on the acknowledgement of rights –to food and to information about food- and of obligations, in private and public behavior, in political participation, in justice, and in cosmopolitanism.

Epithelial Na+ channel activity in human airway epithelial cells: the role of serum and glucocorticoid-inducible kinase 1

description: BACKGROUND AND PURPOSE Glucocorticoids appear to control control Na+ absorption in pulmonary epithelial cells via a mechanism dependent upon serum and glucocorticoid-inducible kinase 1 (SGK1), a kinase that allows control over the surface abundance of epithelia Na+ channel subunits (a-, ß- and y-ENaC). However, not all data support this model and the present study re-evaluates this hypothesis in order to clarify the mechanism that allows glucocorticoids to control ENaC activity. EXPERIMENTAL APPROACH Electrophysiological studies explored the effects of agents that suppress SGK1 activity upon glucocorticoid-induced ENaC activity in H441 human airway epithelial cells, whilst analyses of extracted proteins explored the associated changes to the activities of endogenous protein kinase substrates and the overall/surface expression of ENaC subunits. KEY RESULTS Although dexamethasone-induced (24 h) ENaC activity was dependent upon SGK1, prolonged exposure to this glucocorticoid did not cause sustained activation of this kinase and neither did it induce a coordinated increase in the surface abundance of a-, ß- and y-ENaC. Brief (3 h) exposure to dexamethasone, on the other hand, did not evoke Na+ current but did activate SGK1 and cause SGK1-dependent increases in the surface abundance of a-, ß- and y-ENaC. CONCLUSIONS AND IMPLICATIONS Although glucocorticoids activated SGK1 and increased the surface abundance of a-, ß- and y-ENaC, these responses were transient and could not account for the sustained activation of ENaC. The maintenance of ENaC activity did, however, depend upon SGK1 and this protein kinase must therefore play an important but permissive role in glucocorticoid-induced ENaC activation. © 2012 The Authors.
