Comparison of two anorganic bovine bone in maxillary sinus lift: a split-mouth study with clinical, radiographical, and histomorphometrical analysis
Authors: da Silva Heitor Fontes , Goulart Douglas Rangel , Sverzut Alexander Tadeu , Olate Sergio , de Moraes Márcio
Published: May 2020

Background

Anorganic bovine bone (Bio-Oss®) has been extensively used for reconstruction of posterior area of maxilla in sinus lift procedure; however, a new graft material (Lumina-Bone Porous®), that has a different manufacturing process, has not been yet compared in clinical and histological terms. The manufacturing process of bovine bone graft is related to size and porosity of the particles, and this can change osteoconductive property of the material and bone formation. The use of Lumina-Porus® could improve bone formation, reduce the remaining particles of the biomaterial using a low-cost material. The aim of this research was to compare the clinical, radiological, and histomorphometrical results from maxillary sinus lift with two different anorganic bovine bone substitutes Bio-Oss® (control) and Lumina-Bone Porous® (test).

Results

A split-mouth study was performed with 13 volunteers. The mean bone ridge height in the deepest portion of maxillary sinuses floor was 3.11 ± 0.83 mm in the Bio-Oss® and 2.38 ± 0.75 mm in the Lumina-Bone Porous®. After sinus lift, the Bio-Oss® group shows bone ridge height of 11.56 ± 2.03 mm and Lumina-Bone® of 10.62 ± 1.93 mm. The increase in alveolar bone height scores was significant between pre-augmentation and 6 months after SL in both groups (p< 0.001). No statistical significant difference in newly formed bone in the Bio-Oss® group (20.4 ± 5.4%), and Lumina-Bone Porous® (22.8 ± 8.5%) was histomorphological observed (p> 0.05). On the other hand, the residual graft particles showed significant difference between the Bio-Oss® group (19.9 ± 8.6%) and Lumina-Bone Porous® (14.6 ± 5.6%) (p< 0.05). The survival rate of dental implants for augmented area with Lumina Bone Porous® was 88.88%, while for Bio-Oss® group was 100%.

Conclusion

Both materials Bio-Oss® and Lumina-Bone Porous® can be used in the maxillary sinus floor augmentation with good predictability in clinical, radiographical, and histological point of view.
Lipid-based formulations in cosmeceuticals and biopharmaceuticals
Authors: Ahmad Anas , Ahsan Haseeb
Published: May 2020

The fatty acids containing plant oils have been used as components of cosmetic formulations, and the best cosmetic function has been established for unsaturated fatty acids present in triglycerides. Many oils, fats, waxes, and phospholipids are employed as excipients in cosmetics and personal care products. Antioxidants such as carotenoids, retinoids, and tocopherols are used for their antioxidant properties because of their importance in therapeutic care. For skin care, the most important are oils with high contents of linoleic and α-linolenic acid which reduce the formation of eczemas or atopic dermatitis. These essential fatty acids incorporate into the cell membranes and regenerate the damaged lipid barrier of epidermis and restrict water loss. The unsaturated fatty acids show prominent healing effects on skin inflammation and are used in various cosmetic products. Mineral oils and waxes are also used in several products due to their property of skin tolerance, protection, cleansing, and viscosity. As cosmeceutical formulation, the nanoformulations are effective against irritated and inflamed skin and effective for therapy of atopic dermatitis and psoriasis. The lipid nanoparticles offer advantages of chemical stability and good skin compatibility that can be used for protection against radiation and aging.
The use of modified bite block to improve the safety and efficacy of oral fiber optic intubation in patients with limited neck mobility: a randomized comparative study
Authors: Abdelfattah Shaban Amira
Published: May 2020

Background

One critical aspect of anesthesia is to provide airway management. Fiber optic intubation is the safest solution but can be difficult in patients with limited neck mobility. Insertion of the fiber optic bronchoscope through a modified bite block might facilitate intubation in such patients. Here, we performed fiber optic intubation without and with a bite block that was modified to compare the safety and efficacy of the two techniques.

Method

Sixty adult patients with limited neck mobility who were to undergo elective surgery with mandatory tracheal intubation under spontaneous ventilation were assigned to two groups. In group TR, the traditional technique of oral fiber optic intubation was performed without the use of a bite block. In group MB, the fiber optic was inserted through a modified bite block.

Results

Both groups showed statistically significant increases from baseline in mean arterial pressure and heart rate during the first 3 min after intubation; this increase was marked in the TR group than in the MB group. Hemoglobin oxygen saturation was significantly greater in the MB group than in the TR group. The time to successful intubation was significantly shorter in the MB group than in the TR group. The quality of intubation field shows a significant difference in p value between MB and TR groups with the best result observed in MB.

Conclusion

Oral fiber optic intubation with a modified bite block performed under spontaneous ventilation is safer and more effective than traditional fiber optic intubation for patients with limited neck mobility.
Testing Symptom Severity Thresholds and Potential Alerts for Clinical Intervention in Patients With Cancer Undergoing Chemotherapy
Authors: Shi Qiuling , Lee Ju-Whei , Wang Xin Shelley , Fisch Michael J. , Chang Victor T. , Wagner Lynne , Cleeland Charles S.
Published: May 2020

PURPOSE:

Symptom monitoring is attracting attention as a way to improve adherence to cancer therapy, reduce treatment-related toxicities, and possibly improve overall survival. How reporting thresholds affect symptom alert generation and clinical outcomes is poorly understood.

PATIENTS AND METHODS:

We analyzed data from 38 US health care institutions collected for the prospective Eastern Cooperative Oncology Group–American College of Radiology Imaging Network E2Z02 Symptom Outcomes and Practice Patterns study. Participants were outpatients receiving chemotherapy for breast (n = 642), colorectal (n = 486), or lung cancer (n = 340) who rated symptom severity using the MD Anderson Symptom Inventory at 2 assessment points 1 month apart. Percentages of patients with pain, dyspnea, fatigue, or distress at different thresholds (score of 4-7 on a 0-10 scale) were compared. The percentage of patients whose performance status had worsened at follow-up was used to estimate risk for missing clinically important symptom data by using higher severity thresholds

RESULTS:

At the guideline-recommended threshold of ≥ 4, suprathreshold rates were 60% for any of the 4 symptoms at the initial survey; performance status worsened at follow-up for 27% of all patients with any symptom rated ≥ 4 at the initiate survey. When the threshold was increased to ≥ 7, approximately half of patients (51%) with worsened performance status were not identified.

CONCLUSION:

The burden to clinicians from an alert threshold of ≥ 4 (per many current guidelines) would be substantial. However, setting higher alert thresholds may miss a large percentage of patients who need clinical intervention. These results may inform resource planning when implementing electronic symptom screening at an institutional or practice level.

Published: May 2020

Background: Improving maternal health and reducing maternal mortality are part of the United Nations global Sustainable Development Goals for 2030. Ensuring every woman’s right to safe delivery is critical for reducing the maternal mortality rate, especially in Indonesia. Our study aimed to identify determinants of safe delivery utilization among women in the eastern Indonesia.

Methods: This study was cross-sectional and used data from the 2017 Indonesian Demographic and Health Survey (IDHS). A total of 2,162 women who had their last child in the five years preceding the survey and lived in the eastern part of Indonesia were selected as the respondents. Chi-squared test and binary logistic regression were used to understand the determinants of safe delivery.

Results: Higher child rank and interval ≤2 years (OR: 0.30, 95% CI: 0.19-0.47), unwanted pregnancy at time of becoming pregnant (OR: 1.48, 95% CI: 1.05-2.08), richest wealth quintile (OR: 5.59, 95% CI: 3.37-9.30), more than four antenatal care visits (OR: 3.62, 95% CI: 2.73-4.79), rural residence (OR: 0.49, 95% CI: 0.36-0.66), good composite labor force participation (OR: 1.47, 95% CI: 1.15-1.89), and a good attitude towards domestic violence (OR: 1.33, 95% CI: 1.04-1.69) were found to be significantly associated with facility-based delivery. Higher child rank and interval ≤2 years (OR: 0.49, 95% CI: 0.29-0.83), husband/partner having completed secondary or higher education (OR: 2.18, 95% CI: 1.48-3.22), husband/partner having a non-agricultural occupation (OR: 1.35, 95% CI: 1.00-1.81), being in the richest wealth quintile (OR: 15.69, 95% CI: 5.53-44.50), and three other factors were found to be significantly associated with skilled assistance delivery.

Conclusions: Safe delivery and facility-based delivery among women in the eastern part of Indonesia were determined by several individual and household factors. An open innovation and partnership process that engages the full range of stakeholders should be developed based on local needs.

Peripheral vascular system
Authors: Walter Deborah
Published: May 2020

The clinical examination is an important part of any patient consultation. After the primary survey and taking the patient history, a more in-depth examination is sometimes required to aid making a working diagnosis and help negate other differential diagnoses. The extent of this depends on the stability of the patient and may not be possible in time-critical circumstances. However, clinical examination is an increasing part of paramedic practice owing to the continued expansion of the scope of the paramedic role in both urgent and emergency care. Education on clinical examination concerning each of the main body systems is now an integral part of undergraduate paramedic curricula.

This clinical examination series provides a step-by-step overview for each of the main body systems. Continuing professional development (CPD) is an essential requirement for all clinicians to maintain and demonstrate they are staying up to date and advancing in their roles.

This series gives an overview of each type of examination to support students, newly qualified paramedics and paramedics wishing to use these articles as a CPD development activity and an aide-memoire for clinical practice. This article, which explores the peripheral vascular system, gives an overview of initial examination considerations, including first impressions.

Polycentric governance and policy advice: lessons from Whitehall policy advisory systems
Authors: Diamond Patrick
Published: May 2020

In countries worldwide, the provision of policy advice to central governments has been transformed by the deinstitutionalisation of policymaking, which has engaged a diverse range of actors in the policy process. Scholarship should therefore address the impact of deinstitutionalisation in terms of the scope and scale of policy advisory systems, as well as in terms of the influence of policy advisors. This article addresses this gap, presenting a programme of research on policy advice in Whitehall. Building on Craft and Halligan’s conceptualisation of a ‘policy advisory system’, it argues that in an era of polycentric governance, policy advice is shaped by ‘interlocking actors’ beyond government bureaucracy, and that the pluralisation of advisory bodies marginalises the civil service. The implications of such alterations are considered against the backdrop of governance changes, particularly the hybridisation of institutions, which has made policymaking processes complex, prone to unpredictability and at risk of policy blunders.
Fit to govern? Comparing citizen and policymaker perceptions of deliberative democratic innovations
Authors: Koskimaa Vesa , Rapeli Lauri
Published: May 2020

Democratic innovations, such as the introduction of deliberative mini-publics, have attracted increasing attention. The assumption is that involving citizens more directly in policymaking offers a way to address the widespread decline in public trust in the democratic process and traditional forms of engagement, such as voting in elections. While a thriving literature discusses the merits of mini-publics from a citizen perspective, scholars have neglected the views of policymakers. To fill the gap, we draw on two recent surveys conducted in Finland to examine citizens’ and policymakers’ attitudes to mini-publics. The data show that citizens report high levels of trust in the capacity of a deliberative citizen body to produce meaningful policies. However, policymakers are more sceptical about their value. This finding is important because it may well have implications for the willingness of policymakers to create mini-publics and take their recommendations into account.
Log-periodic temporal apertures for grating lobe suppression in k-space tomography
Authors: Ryan Conor J. , Beardell William L. , Murakowski Janusz , Ross Dylan D. , Schneider Garrett J. , Prather Dennis W.
Published: May 2020

Millimeter-wave (mmW) imaging receivers have demonstrated the ability to sense radio-frequency (RF) waves using traditional phased antenna array techniques, and, through a coherent photonic up-conversion process, image these waves using free-space optical systems. Building upon the idea of coherent up-conversion, k-space tomography extends the functionality of the millimeter-wave imaging receiver as a two-dimensional spatial processing unit to three-dimensional sensing with the addition of frequency detection. In this configuration, an arrayed waveguide grating, or temporal aperture, is implemented following the photonic up-conversion of RF signals received by the phased array. These waveguides of varying length add a spectral beam-forming network to the existing spatial beam-forming of the mmW-imaging receiver. The introduction of three-dimensional phase information to the imaging system disrupts the ability to directly image the RF signal distribution on a photo-detector array, requiring the application of tomographic algorithms to reconstruct the power distribution of the received signals. In order to receive and properly recover the spatial-spectral distribution of RF sources, the antenna array and temporal array must be sampled adequately to avoid introduction of grating artifacts into the system response. Grating lobes, an artifact of regular spacing of elements within a grating, restrict the alias-free field of regard for antenna arrays, or the free spectral range for time-delay based arrays, thus limiting the spatial-spectral monitoring of RF sources via the k-space imaging modality. To alleviate this constraint, we present a non-uniform log-periodic array sampling for the k-space tomographic time-delay based aperture, greatly increasing the free spectral range of the system while maintaining the number of existing channels.
Multimode exposed core fiber specklegram sensor

Published: May 2020

The inception of photonic crystal fibers (PCFs) allowed for unprecedented tailoring of waveguide properties for specialty sensing probes. Exposed core microstructured fibers (ECFs) represent a natural evolution of the PCF design for practical liquid and gas sensing. Until now, to the best of our knowledge, only single-mode or few-modes ECFs have been explored. In this Letter, we demonstrate a highly multimode ECF with a lateral access that extends throughout the whole length of the fiber. The ECF is operated as a fiber specklegram sensor for assessing properties of fluids and interrogated using a simple and low-cost setup. The probe exhibits a refractive index resolution and sensitivity of at least

Resolution enhancement in an extended depth of field for volumetric two-photon microscopy
Authors: He Hongsen , Kong Cihang , Chan Ka Yan , So W. L. , Fok Hiu Ka , Ren Yu-Xuan , Lai Cora S. W. , Tsia Kevin K. , Wong Kenneth K. Y.
Published: May 2020

The resolution enhancement over the extended depth of field (DOF) in the volumetric two-photon microscopy (TPM) is demonstrated by utilizing multiple orders of Bessel beams. Here the conventional method of switching laser modes (SLAM) in 2D is introduced to 3D, denoted as the volumetric SLAM (V-SLAM). The equivalent scanning beam in the TPM is a thin needle-like beam, which is generated from the subtraction between the needle-like 0th-order and the straw-like 1st-order Bessel beams. Compared with the 0th-order Bessel beam, the lateral resolution of the V-SLAM is increased by 28.6% and maintains over the axial depth of 56 µm. The V-SLAM performance is evaluated by employing fluorescent beads and a mouse brain slice. The V-SLAM approach provides a promising solution to improve the lateral resolutions for fast volumetric imaging on sparsely distributed samples.
Spontaneous diametric-drive acceleration initiated by a single beam in a photonic lattice
Authors: Pei Yumiao , Wang Zhaoyuan , Hu Yi , Lou Cibo , Chen Zhigang , Xu Jingjun
Published: May 2020

We demonstrate that a single Gaussian-like beam can self-bend during nonlinear propagation in a uniform photonic lattice. The two components of the beam experiencing normal and anomalous diffractions spontaneously separate and form a pair in a diametric-drive acceleration due to nonlinear action. Such a diametric drive generally describes a jointly accelerating behavior of two beams analogous to positive- and negative-mass objects. The influences of the initial momentum of the input beam and the nonlinear strength are considered in this process. We further realize a self-bending propagation for a partially coherent light beam and discuss the impact of incoherence on the acceleration strength.
Preparation and properties of Tm-doped SiO2-ZrO2 phase separated optical fibers for use in fiber lasers
Authors: Vařák Petr , Mrázek Jan , Blanc Wilfried , Aubrecht Jan , Kamrádek Michal , Podrazký Ondřej
Published: May 2020

Zirconium oxide (ZrO2) is a perspective co-dopant of rare-earth ions in silica fibers for use in fiber lasers. ZrO2 nanoparticles increase the solubility of rare-earth ions and enhance their luminescence properties. In this paper, we report on the fabrication of Zr-Tm codoped silica fibers using the MCVD method combined with modified solution-doping technique. Several fibers with different dopant concentrations were prepared and their optical properties were studied. It was found that increasing Zr concentration leads to the creation of larger ZrO2 nanoparticles which causes unwanted attenuation. Optimal Zr concentration was found to be 1 at. %. The fiber with optimal Zr concentration and Tm concentration of 260 ppm exhibited 1.8 µm fluorescence lifetime of 420 ± 10 µs. For the first time in literature, we have demonstrated laser operation in a Zr/Tm-codoped silica fiber. The threshold for laser operation was determined to be 233 mW and the slope efficiency of 72.7% was achieved. MCVD combined with modified solution doping proved to be a feasible method of preparation of Tm-doped SiO2-ZrO2 optical fibers for use in fiber lasers.
The Way of the Artist Educator paradigm: Fusing artistic studio practice and teaching pedagogy
Authors: Strickland Christopher M.
Published: May 2020

The purpose of this autoethnographic study is to examine the experiences of visual arts educators who identify themselves as Artist Educators. In particular, this article investigates how these Artist Educators perceive the fusion of their artistic studio practice with their teaching pedagogy, and how the perception defines their identity and impacts their creative and classroom practices. This study involved a focus group of six individuals, including the researcher. All the participants were practising artists, currently employed or recently retired K-12 visual arts educators certified in the states of Maine or New Hampshire, and members of the Kittery Art Association. This study used a combination of interviews and an arts-based method for data collection. All the data were analyzed and resulted in seven findings that culminated in the Way of the Artist Educator – an alternative paradigm for a quality and holistic twenty-first-century visual arts education. This article presents the paradigm, discusses the study’s implications and offers suggestions for future research.

Film criticism and the legitimization of a New Wave in contemporary Greek cinema
Authors: Sifaki Eirini , Stamou Anastasia
Published: May 2020

Contemporary Greek cinema garnered a great reputation in recent years, including Oscar nominations, numerous awards and distinctions in international festivals and also worldwide media coverage. The emergence of a new group of filmmakers whose creativity and avant-garde aesthetics were stimulated and heightened by the social and economic crisis was first marked by media critics (film critics and cultural journalists). As journalistic art criticism plays a prominent role in the legitimization of cultural products and artistic genres, this article examines the way in which professional film critics and journalists, both in Greece and abroad, described, evaluated and labelled the ‘Greek New Wave’. In line with cultural evaluation theories, we conducted a content analysis of film criticism articles in order to explore how professionals have reviewed and deployed their arguments towards this new phenomenon. Our results indicate that film criticism decisively influenced the Greek New Wave’s shaping and legitimization in the film industry. Even though film critics and journalists hesitated to adhere to a specific name for this phenomenon in Greek cinema, their discourses and interpretations have been based on the films’ break with previous film practices and representations of Greek society and the paradox between a ‘collapsing country’ and a flourishing arthouse cinema.
Reclaiming Greece’s national star: Aliki Vougiouklaki, from sex kitten to working girl
Authors: Kourelou Olga
Published: May 2020

During the so-called ‘Golden Age’ of Greek cinema (roughly from 1950 to 1970), Aliki Vougiouklaki emerged as Greece’s biggest star. Yet, although her image remains extremely familiar, it is largely misconstrued in both popular and critical discourses about her. This article shifts the focus from conventional readings of Vougiouklaki’s star persona as ideologically and sexually conservative, mainly due to her embodiment of the sex-kitten type, to the work dimension of her image – a heretofore unexplored facet of her persona. A careful look at her early films, the control she exercised over the construction of her star image, as well as the ways in which it circulated off-screen reveals a dogged, stereotypically ‘masculine’, devotion to her work and career, making Vougiouklaki into a powerful and progressive image of femininity in post-war Greece.
Comics, memory and migration: Through the mirror maze of Soloup’s Aivali
Authors: Gedgaudaitė Kristina
Published: May 2020

This article turns towards the legacy of the Greco-Turkish War (1919–22) in contemporary Greek culture. Drawing on the conceptual frameworks of postmemory and intergenerational transmission of trauma, it examines the Greek graphic novel Aivali by Soloup (2014, translated into English in 2019) in order to discuss aesthetics and practices set in motion by the memory of Asia Minor, when the relay of remembrance reaches the third generation. The article demonstrates how the fragments of memories that the grandchildren of Asia Minor refugees inherited from their ancestors find their way into comics panels, through which those memories are reassembled into a public visual archive. At the same time, the graphic novel also performs a reconstitution of the Greek literary canon, when the works of Greek and Turkish writers are called upon to fill in the gaps in the family story. Ultimately, it is argued that affective connections fostered through reading Aivali ensure that memory can travel across time and lead to new encounters, bringing back reminiscences of Asia Minor afresh to communities’ collective imagination.
Segurança comunitária e proteção civil

Les trois acteurs de la conduite sont : le Conducteur, le Véhicule et l’Infrastructure. L’Algérie est classée parmi les pays qui enregistrent un nombre élevé d’accidents ces dernières années. Les statistiques du centre national de prévention et sécurité routière algérien, montrent que les causes directes des accidents de circulation sont liées à l’homme, au véhicule et à l’environnement. Le comportement humain se manifeste par l’excès de vitesse, suivi de l’alcoolémie et non-respect du code de la route. Nous proposons des mesures qui contribueraient à la réduction des accidents ; Ceci par l’adoption et l’application des lois, prenant en compte les facteurs de risque, les compagnes de sensibilisation et de prévention des catégories sociales concernées par la mortalité routière. Ces propositions peuvent être lancées à travers les mass-médias, la réduction de l’utilisation du véhicule individuel et l’encouragement du transport commun en contribuant à la préservation de la santé humaine et la lutte contre l’apparition des maladies cardio-vasculaires.

Reading Thoreau in Another’s Voice Reading Thoreau
Authors: LaLiberty Ryan
Published: May 2020

Reading Thoreau in Another’s Voice Reading Thoreau is an experimental sound work that elucidates the complex network of materialities present in literature. Two sound sources are taken from two public-domain audio readings of Henry David Thoreau’s Walden. The two verbatim excerpts — from the chapter “Sounds” where Thoreau expresses his at times ambivalence, at times exuberance, but constant alertness to the soundscape of Walden Pond — are fed into a modular synthesizer. Within the processing domain of the synthesizer, each excerpt is fed into an envelope detector that traces the volume contour of the reading, creating an extractable mimesis of the auditor’s rhythm. These rhythmic envelopes are then applied to the opposite excerpt, forcing the reader to read in the rhythm of the other’s voice. The resulting audio stutters and glitches as one reader opens and closes the mouth of the other. In concert, both readers open up pulsating oscillators that accompany the readings. Sound here is voltage, apart from all semantic content. As the rhythm of the reader’s words is extracted, so too are the extra-semantic components that emerge from the noise of the recording. The network of Walden is broadened thus to include the bodies of its auditors and the noises of its medium.
The Art of Vanishing

Published: May 2020

The audio poetry mix titled "Umetnost Gubljenja" (The Art of Losing / Vanishing) uses cut-up technique in order to mix and adjust the text of the poem "Umetnost Gubljenja" to the audio poetry form. An unknown program was used for mixing in this totally homemade art work, authored by Vladimir Milojković (sometimes published under the name Vladimir Vladda Miloykovitch). The mix is 6 minutes and 35 seconds long, mono sound, mp3 format. Conceptually, it is, in a certain way, socially engaged poetry, questioning the role of art in the modern world. Effects influencing the listeners were achieved through repetition of crucial words and tone changing.

It is recommendable to listen the mix via headset for better experience.
Paisagem Sonora de Emma
Authors: Pinheiro Sara
Published: May 2020

Esta peça é parte de uma instalação audiovisual de vários ecrãs, concebida pelas artistas visuais Mieke Bal e Michelle Williams-Gamaker. A instalação é baseada no romance de Flaubert Madame Bovary (1856). Emma (Madame B.) é uma ouvinte atenta e sensível ao ambiente que a rodeia. A banda sonora (quer na instalação, quer na longa-metragem) foi desenvolvida através de uma série de motivos sonoros que servem como caracterização sonora da personagem. Escutar estes motivos sonoros é um exercício de “focalização sonora”: os objectos que a caracterizavam fa-lo-iam sonoramente também. A paisagem sonora de Emma reflecte os sons acumulados de uma vida individual, que simultaneamente forma e limita o espaço que a define. Estes sons marcam e traçam a história da personagem, eventualmente delineando ‘a sua expansão no mundo tanto quanto a sua reclusão no mesmo’.

Deve ser ouvida preferencialmente com monitores, desde que não haja mais sons a interferir. A peça deverá ocupar uma sala vazia.
Language Has No Positive Terms
Authors: Prescott-Steed David
Published: May 2020

This sound art composition is a meditation on the arbitrariness of linguistic signs and the idea that language has no positive terms: "signs have no special right to mean something in particular and not something else" (Bignell: 9). As a first-time father, the interactions I have with my four-year-old daughter are mostly related to my responsibility to facilitate her sensory exploration of the world around her. This includes supporting her formalisation of linguistic expression and numeracy skills through story recall and construction, number identification, and pattern/rhythm awareness. These language-based learning activities benefit early childhood development by progressing a child's social awareness, confidence and resiliency. A tension exists, therefore, between the power of language as a vital navigational tool and the unassailable instability of meaning.

As a creative response, this composition features extracts from audio recordings of our conversations. The fragments of utterances, like the synthetic buzzing that returns and haunts, shift between audibility and inaudibility, meaning and non-meaning. Each time it's played, digital audio technology brings our absence into the present; we become acousmatic textures inside the body of the listener who "cannot listen away as one can look away" (Connor: 133), oscillating the small bones in the middle ears and sending electrical signals to the brain . Through this treatment of language, we may be emptied of meaning but not of the positive meaningfulness of our interactions.

RESUMEN: En este artículo se analiza la representación en la Cámara de Diputados de Venezuela durante el período de 1994-1999 para contextualizar la candidatura presidencial de Hugo Chávez. En 1993, el sistema bipartidista en Venezuela fracasó y se usó una nueva ley electoral mixta por primera vez. Estas reformas reforzaron la influencia congresista de la patronal y los sindicatos, en vez de ampliar los patrones de representación para incluir las preocupaciones de los intereses emergentes.El fracaso de las reformas moderadas para mejorar la representación favoreció a candidaturas de políticas que apoyaron las agendas políticas radicales, como la de Hugo Chávez.ABSTRACT: This article examines representation in the 1994-1999 Venezuelan Chamber of Deputies to contextualize the presidencial candidacy of Hugo Chávez. In 1993, the Venezuelan the two-party system broke down and a new mixedmember electoral law for Congress was implemented. These reforms reinforced the congressional influence of business and labor rather than broaden representation patterns to include the concerns of emerging interests. The failure of moderate reforms to improve representation created conditions that favored the candidacies of politicians, like Hugo Chávez, who endorsed radical political agendas.
Tiempos de cambios en las actitudes políticas de los venezolanos
Authors: Pereira Almao Valia
Published: May 2020

RESUMEN: A objeto de establecer los rasgos principales de las actitudes políticas en Venezuela, el presente trabajo examina la consistencia de las lealtades partidistas, el estilo de democracia prevaleciente e indaga en las divisiones ideológicas y sociales respecto de la desigualdad social, haciendo uso del método estadístico para el análisis de encuestas y la comparaÇión de datos provenientes de encuestas hechas en 1973, 1983, 1993 y 1995 con fines de investigación científica. Se concluye que la transferencia partidista en el proceso de socialización política se ha debilitado, pero permanece alta la adhesión democrática dentro de una concepción procedimental de la misma y las diferencias sociales e ideológicas respecto de la igualdad social se están produciendo, todo lo cual modifica el consenso que propició la regularidad democrática entre 1968 y 1988 y presagia cambios significativos en el sistema político que sugieren el seguimiento analítico en lo sucesivo de las actitudes políticas para establecer las tendencias.ABSTRACT: To determine the main features of the political attitudes in Venezuela, this article examines the consistency of party loyalties, the prevailing style of democracy and the social and ideological divergences regarding social inequality, by means of the statistical analysis of surveys and the comparison of survey data collected in 1973, 1983, 1993 and 1995.The conclusion is that the party transference in the process of political socialization has weakened, whereas the democratic adherence under a procedural conception of democracy remains high. Social and political divergences regarding social inequality are also present, all together modifying the consensus that promoted the democratic order between 1968 and 1988 and foreseeing significant changes in the political system which advise to follow analytically the evolution of the political attitudes and establish their trends.

RESUMEN: Si bien Venezuela no es un caso representativo de nuevo régimen democrático, ya que ha funcionado ininterrumpidamente como tal desde hace treinta años, sí existen una serie de elementos que permiten plantear la existencia de una importante ruptura en la composición de la élite parlamentaria, constituyendo las dos últimas legislaturas un punto de inflexión claro en el desarrollo político venezolano y una muestra de la ruptura definitiva del bipartidismo que venía funcionando desde 1958.El objeto de este artículo es el estudio de la estructura sociológica de la élite parlamentaria en el período 1993- 1998, comparando algunas particularidades de la misma con características de la actual legislatura intentando establecer rupturas y continuidades entre ambas Cámaras. En el mismo se contrastan hipótesis clásicas, al estilo de las recogidas por Putnam y Von Beyme sobre la relación entre determinadas características sociodemográficas y demográficas y la élite política.ABSTRACT: Although Venezuela is not a representative case of new democracy, because it is established thirty years ago, there are now some important element that implied an break in parliamentarian elite composition.

Some clasical hipothesis, as posited by Von Beyme and Putnam about correlation sociademoghapich characterists and political elites, are contrasted in the article.
Democracia y dilema eficiencia-equidad en la descentralización local en Venezuela
Authors: García-Guadilla María Pilar
Published: May 2020

RESUMEN: La descentralización es uno de los mecanismos mediante el cual el Estado central transfiere competencias políticas y administrativas a las localidades, ya sea con la finalidad de fortalecer la participación política, lograr eficiencia estatal o para buscar la gobernabilidad. En algunos países latinoamericanos como Colombia, Chile, Argentina, Brasil, Costa Rica se han impulado procesos de descentralización con el fin de racionalizar la actividad estatal y, precisamente, contribuir a la gobernabilidad.En Venezuela la Comisión para la Reforma del Estado (COPRE) implementó la descentralización en 1988 como una forma de superar el modelo estado céntrico, caracterísitico de las últimas décadas en el país. El proceso no estuvo acompañado por cambios constitucionales, lo que condujo a conflictos entre diversas normas y al consiguiente retraso en la implementación de las nuevas políticas. El ejercicio descentralizador se está desarrollando principalmente a nivel político, por ejemplo, en los municipios de Chacao, Baruta, El Hatillo y Libertador, que pertenecen al Area Metropolitana Interna de Caracas. Así, el proceso descentralizador se vive con diferencias marcadas resultantes del tipo de administración implementada desde la alcaldía, la mayor o menor disponibilidad de resursos económicos y humanos, la población y la pobreza.ABSTRACT: Decentralization is one of the mechanisms by which the central State transfers political and administrative competences to the localities, sometimes with the purpose of strenghtening political participation, to achieve state efficiency of to look for gobernability. In some Latín American countries such as Colombia, Chile, Argentina, Brasil, Costa Rica have been decentralization processes impulsed to rationalize the public activity and, precisely, to contribute to gobernability.In Venezuela the Comission for the State Reform (COPRE) implemented the decentralization in 1988 as a way of excelling the centric state modcl, characteristic of the last decades in the country. This process was not acompanied by constitutional changes, what drived to conflicts between several norms and the consequent delay of the new policies implementation. The decentralization is being developed mainly at the political level, for example, in the Chacao, Baruta, El Hatillo and Libertador municipalities, which belong to the Intern Metropolitan Area of Caracas. So, the decentralization process is lived with pronounced differences as a result of the kind of administration implemented from the mayoralty, the high or less availability of human and economic resources, the population and the poverty.
Venezuela, los cambios globales y su política exterior
Authors: Romero Carlos A.
Published: May 2020

RESUMEN: El mundo ha avanzado hacia la globalización, lo que exige que América Latina, con poca relevancia internacional y con una situación económica crítica, busque ajustarse a las nuevas exigencias internacionales mediante "la desregulación y la coordinación económica". También se hace prioritaria la búsqueda de la integración regional tanto a nivel público como privado a través de instituciones como Mercosur y la Comunidad Andina de Naciones.Este artículo plantea las incidencias de la globalización y la integración en la política exterior venezolana y los mecanismos a aplicar para ajustarse al nuevo modelo mundial. Tres son los puntos prioritarios en este sentido: los cambios globales, el petróleo y la política exterior.La situación de Venezuela como país proveedor de petróleo a Estados Unidos le ha permitido ser conservador en sus posiciones y asumir la apertura económica de forma más discreta al resto de países de la región. La democracia es otro tema que rodea las relaciones internacionales, especialmente lo relativo a los derechos humanos y al buen gobierno, y del cual Venezuela se beneficia al procurar un espacio idóneo para su desarrollo.ABSTRACT: The world has moved towards globalization, which means that Latin America, that has low international leverage and a critical economic situation, has to search for an adjustment to the new international demands by means of "deregulation and economic coordination". It is also a priority to pursue the regional integration at the prívate and public levels through institutions such as Mercosur y la Comunidad Andina de Naciones.This article poses the incidences of globalization and integration in the Venezuelan international policy, as wcll as the mechanisms of adjustment to the new world orden. Three elements are pointed out as priorities: the global changes, the petroleum, and the international policy.The situation of Venezuela as a US supplier of petroleum has permitted this country to be more conservative in its positions and to assume the economic opening in a more discrete fashion as compared to the rest of the countries in the region. Democracy is another issue surrounding the international relations, specially in what refers to human rights and good government, and from which Venezuela benefits when pursuing the appropriate developmental environment.
La visión exiliar de Juan Gelman
Authors: Pérez López María Ángeles
Published: May 2020

RESUMEN: En el poeta argentino Juan Gelman (1930), la traumática experiencia del exilio no viene a conformar sólo una parte importante de su producción, la comprendida entre 1975 y 1988, sino que además, y fundamentalmente, establece el desplazamiento hacia zonas de sentido en las que el lenguaje es también «el expulsado», el «vacío-pasión», «la marca de una ausencia que no cesa de no escribirse», en sus propios términos. De ahí que resulte tan relevante su encuentro con la poesía mística española, en la medida en que el místico es un exiliado de Dios (Citas y Comentarios, 1982), y con la poesía sefardí (Dibaxu, 1994), «como si la soledad extrema del exilio me empujara a buscar raíces en la lengua, las más profundas y exiliadas de la lengua».ABSTRACT: In the life of the Argentine poet Juan Gelman (1930), the traumatic experience of exile informs not only an important part of his production, the one that falls between 1975 and 1988, but also, and fundamentaly, it establishes the displacement to areas of significance in which language is also «the rejected», the «empty-passion», «the sign of an absence that does not finish writing itself», in his own words. From this, one discovers the importance of his encounter with Spanish mystical poetry, to the extent that the mystic is estranged from God (Citations and Comentaries, 1982) and with Sephardic poetry (Dibaxu, 1994), «as if the extreme solitude of exile compelled me to search for roots in language, the deepest and most estranged from language».
Avatares del personaje artificial en la novela argentina de los 90
Authors: Mesa Gancedo Daniel
Published: May 2020

RESUMEN: A partir de una incitación de Macedonio Fernández en el Museo de la Novela de la Eterna, el siguiente trabajo estudia cómo se manifiesta la reflexión metaliteraria en tres novelas argentinas de los años 90 (dos de César Aira, una de Osvaldo Soriano) en las que diversos avatares del «personaje artificial» desempeñan un papel protagonista. Analizando los rasgos del creador, las características de la criatura artificial y las relaciones entre ésta y el artificio de la creación, se revela que el personaje artificial (autómata, robot o clon) se asocia en esos textos a la crisis de la verosimilitud que caracteriza a una cierta narrativa contemporánea, cuya única pretensión de sentido (aparentemente) reside en la revelación de la actividad narrativa misma.ABSTRACT: Based on an idea from Museo de la Novela de la Eterna, by Macedonio Fernández, this paper studies the metaliterary reflection in three Argentine novels of the 90’s (two of them by César Aira; one by Osvaldo Soriano). In these novels, the «artificial character» plays a principal role. By analysing the features of the creator and of the creature, as well as the relation between the «artificial creature» and the «artifice of the creation», it becomes obvious that the «artificial character» (automaton, robot or clone) is tied in these texts to the «crises of the credible», so present in an important number of contemporary narratives, which (apparently) only can find their meaning in the revelation of the narrative activity itself.
