El valor de la producción científica y del paper para ingresar a la carrera de investigador del CONICET

This paper analyzes the assessment made of the scientific and technological production of applicants to the Career of Scientific Researcher (CIC) of the National Council of Scientific and Technical Research (CONICET) of Argentina, in the initial category, called Assistant Researcher. In particular, it discusses the explicit evaluation criteria for admission to this career, in its different modalities and areas of knowledge, which were disseminated by CONICET in the 2018-2019 calls, which were categorized for comparative purposes to identify the relative value assigned in each area to scientific production. In addition, in order to analyze how these general criteria are applied in the different sub-commissions, issues observed in opinions received by applicants were taken into account. Finally, a series of proposals are presented that are considered to contribute to decentralizing the place of the paper as a central factor in the evaluation.
Flood Mitigation Parameters of Apiti Wetlands Soil in a Segment of Mamu River Basin, Nigeria

Wetlands are essential components of our global ecosystem. They have important functions which include maintenance of the environment through mitigating the degree of flooding, regulating the local and global climate and lessening the degree of erosion by trapping sediments. The aim of this research is therefore to investigate how relevant wetland parameters mitigate flood in Apiti wetland soil of middle River Mamu basin of Nigeria. For the purpose of the study, the wetland was divided into three; A (the upland region), B (the flood plain), and C (the raffia palm area). The soil flood mitigation parameters examined are bulk weight, moisture content, and saturation water content. These were employed to calculate the volume of flood mitigation within three sub-sites of the wetland. The statistical methods employed were One Way ANOVA and Students t-Test to see whether differences occur in the flood mitigating ability of the soil. Results obtained show that flood mitigation was highest within study site B (flood plain) with 6.4 × 106 m3 volume of flood mitigation and lowest in site A (upland region) with 1.5 × 106 m3. In conclusion we recommended that the study be scaled up to other wetlands in Nigeria.
Heteroepitaxial growth of tin‐doped indium oxide films on single crystalline yttria stabilized zirconia substrates

Heteroepitaxial growth of tin‐doped indium oxide (ITO) film was achieved for the first time by using single crystalline yttria stabilized zirconia (YSZ) as substrates. The epitaxial relationship between ITO film and YSZ substrate was ITO[100]∥YSZ[100]. By comparing the electrical properties of this epitaxial ITO film with that of a randomly oriented polycrystalline ITO film grown on a glass substrate, neither the large angle grain boundaries nor the crystalline orientation were revealed to be dominant in determining the carrier mobility in ITO films.
Nocturnal carbon efflux: reconciliation of eddy covariance and chamber measurements using an alternative to the u.-threshold filtering technique

Micrometeorological measurements made on single towers often underestimate nighttime respiration of terrestrial ecosystems because they cannot account for vertical and horizontal advection, thereby causing systematic errors in estimates of net ecosystem carbon exchange. We show that there is a maximum in the sum of the turbulent flux and change in storage of CO2 in the early evening, Rmax, that is in close agreement with concurrent and independent estimates of net carbon exchange from soil and plant chambers.We hypothesize that the peak occurs because there is a time delay between the onset of radiative cooling and the development of temperature gradients that are strong enough to initiate thermally-driven horizontal and vertical flows that remove the stored CO2. We propose taking advantage of this time delay to develop relationships between Rmax and soil temperature and moisture. The new parameterization leads to realistic values of nighttime respiration, and therefore to improved estimates of net ecosystem exchange.
The state of breeding birds in Greece: trends, threats, and implications for conservation

Summary Birds are suffering from steep population declines on a global scale and they are one of the few taxonomic groups for which these declines are well documented by long-term monitoring data. This study provides a synthesis of the status of the breeding birds of Greece. To this aim, we retrieved population size estimates from six sources spanning 22 years (1992–2014) and calculated species’ trends in Greece. Using the IUCN Red List assessments for each species we assessed whether ecological traits including habitat and diet preferences were associated with species’ trends and conservation status in Europe and determined major threats affecting birds in Greece. Moreover, we assessed the importance of Important Bird & Biodiversity Areas (IBAs) in terms of declining trigger species. Results showed that almost one fifth of the breeding birds in Greece have declining populations. Raptors were found to be the most threatened group of birds whereas the highest declines by dietary group were observed in scavengers, with 60% of species showing a decreasing trend. The most common threats were those that cause habitat alteration and degradation as well as more direct effects such as poisoning. Our results suggest that restoration of habitat and ecosystem functions along with the management of protected areas and improvement of legislation should be the main conservation actions undertaken and pinpointed the IBAs where they should be prioritized for implementation. Finally, further research, especially on specific drivers of population change, along with further examination of current and past population trends, will increase the power and accuracy of future regional Red List assessments especially concerning the breeding species for which the country bears the greatest responsibility.
Tendencia al sobrepeso y obesidad en jugadores de fútbol americano universitario en México (Trending overweight and obesity in college football players in Mexico)

The objective of this study is to evaluate the body status of college football players, and to see their tendency towards overweight and obesity. It is also intended to assess body status by playing position. A total of 90 players (28 linemen, 47 skill players and 15 big skill players) (22.44 ± 1.71 years old) from a major league college football team in Mexico participated. In which anthropometric measurements and evaluations were made with dual X-ray absorptiometry (DEXA) to obtain body mass, body mass index (BMI), abdominal circumference and fat mass. Most have a BMI of overweight with 46 players, 31 players have a BMI of obesity type I, II and III, and only 13 players have a BMI of normal weight. In body weight, BMI, fat percentage and abdominal circumference, linemen obtained higher values (p < .05), while those of skill players obtained lower values (p < .05). Most players have problems of overweight and obesity, although with a fat percentage and an abdominal circumference in the moderate limit, it is necessary to establish feeding and training programs to improve the body status of players.
Porous Silk Fibroin Membrane as a Potential Scaffold for Bone Regeneration

The requirements for scaffolds for bone tissue engineering include appropriate chemistry, morphology and structure to promote cell adhesion and synthesis of new bone matrix. Silk fibroin (SF) represents an important biomaterial for biomedical application, due to its suitable mechanical properties, biodegradability, biocompatibility, and versatility in processing. Our group has developed a new method to obtain a porous SF membrane, and the study of its potential for use as a scaffold for bone regeneration was the aim of this study. Porous membranes were obtained from SF solution, through the compression of a material generated by phase separation. For in vitro calcification experiments, porous SF membrane samples were immersed in SBF at pH 7.4 placed in polyethylene flasks. The experiments were carried out for seven days, at 36.5±0.5 °C. After 48 and 96h, the solutions were changed for fresh SBF with the ion concentration 1.5-fold higher than that of the standard one, to accelerate the calcification process. The characterization of morphology and composition of samples was performed by using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), respectively. The SEM micrographs indicated that the porous SF membranes presented calcium phosphate deposits after undergoing in vitro calcification. These results were confirmed by EDS spectra, which showed a stoichiometric molar Ca/P ratio ranging from 1.27 to 1.52. This fact may suggest that calcification deposits consisted of mixtures of HAP (Ca/P ratio = 1.67) and transient HAP precursor phases, such as octacalcium phosphate (Ca/P = 1.33) and dicalcium phosphate dehydrate (Ca/P = 1), indicating early stage mineralization. The porous silk fibroin membrane analysed in the current study is a promising material to be used as scaffolds for bone regeneration.

Attachment style and clinical outcome within a DBT-informed Therapeutic Community

Purpose – There is evidence that attachment style and clinical outcomes are related within Therapeutic Communities (TCs). This study sought to examine any possible relationships between self-reported adult attachment style, therapy programme engagement and measures of psychological distress and dissociation on admission and discharge within a residential TC. Design/methodology/approach – Ex-clients of the TC were contacted by post and invited to take part in this service evaluation. Additional data was sourced from a database of routinely collected outcome measures. Of 281 ex-clients, the final sample in this study was N=32. Findings – When attachment style is conceptualised dimensionally, participants identified most strongly with a fearful attachment style, and least with a preoccupied or secure style. A range of attachment styles were reported. A significant association was apparent between self-reported secure attachment and reduced levels of psychological distress upon discharge from the TC. The potential for changes in client attachment patterns following TC membership is discussed. Originality – To date, this is the first known study to report on the relationship between self-reported adult attachment style and psychological outcomes specifically for women with self-defeating behaviours within a TC. Research limitations/implications – The small sample size and correlational nature of this study means that results should be interpreted cautiously. Nevertheless, results are of clinical relevance for inpatient or residential therapy programmes (including TCs). Such programmes should routinely assess client attachment style to ensure appropriate interventions and adaptions are implemented.
Modificación de memorias maladaptativas durante el sueño y la vigilia: una visión interidisciplinaria

Consolidated memories can return to a labile state after a reminder presentation (cue associated to the initial learning) followed by a re-stabilization process known as reconsolidation. Furthermore, sleep has an active role in the formation and modification of memories, as well as in decreasing the emotional tone of the experiences. During sleep, new memories are reactivated, reinforced and integrated into pre-existing networks. Within the therapeutic context, old memories can be retrieved according to the subject's needs, and this could be triggering repeated labilization/restabilization processes, perhaps without being aware of it. In this review we discuss the neuroscientific advances regarding memory reactivation and modification during sleep and wakefulness, as well as the latest approaches in psychotherapeutic therapies for anxiety disorders, with the aim of thinking about a more interdisciplinary practice.
Nitrate/ammonium ratio effect on the growth, yield and foliar anatomy of grafted tomato plants

The vigorous behaviour of a rootstock modifies the growth and yield of a plant variety or hybrid, altering the plant nutritional requirements. The purpose of this work was to study four ratios of NO3–/NH4+ (100/0, 92/8, 85/15 and 80/20%) over the growth, leaf anatomy and yield of grafted and ungrafted tomato plants. We used a fully randomised experimental block design with factorial arrangement of 2 × 4 (grafted and ungrafted plants and four ratios of NO3–/NH4+), on eight treatments in total with four replicates each, using Tukey’s mean comparison test (P ≤ 0.05). The rootstock was ‘Silex’ by Fito Seeds, with the ‘El Arrojado’ graft (variety) by Gene Seeds. The graft produced an increase in growth, dry biomass production, stomatal density, trichome number, epidermal cell density, fruits per plant, average fruit weight, fruit size and total soluble solids, in comparison with the ungrafted tomato plants. In most of the assessed variables, the grafted tomato plants gave their best response at an 85/15% NO3–/NH4+ ratio; while the ungrafted plants performed better at a 92/8% NO3–/NH4+ ratio. The response of the grafted plants to the different NO3–/NH4+ ratios suggests that grafting induces tolerance to NH4+.
Super-twisting algorithm with fast super-twisting disturbance observer for steer-by-wire vehicles

The control performance of a vehicle steer-by-wire (SBW) system can be seriously affected by vagaries of tyre-road conditions and external disturbance. Aiming at the problem of fast estimating and compensating the time-varying disturbance torque acting on the front wheels under different working conditions, this article presents a super-twisting algorithm (STA) combined with fast super-twisting disturbance observer (FSTDO) control scheme. At first the SBW system is modelled according to the experiment plant. Secondly, the FSTDO is designed according to SBW system model. A fast reaching law is adopted to accelerate the sliding variable convergence rate and enhance the response speed of the observer. The FSTDO-STA controller adopts STA control in closed-loop system. The control signal is continuous, so that, the chattering could be inhibited. The stability of FSTDO error dynamics and closed-loop dynamics is proved in the sense of Lyapunov. Finally, comparative verification experiments are carried out to demonstrate the validity of FSTDO-STA. The FSTDO-STA controller can quickly estimate and compensate disturbance torque under various operating conditions. Compared with other comparative algorithms, the proposed controller has some advantages in response speed, control accuracy and robustness. And it was corroborated by the experimental results.
Electrical testing of gold nanostructures by conducting atomic force microscopy

We devised a method for the reliable electrical testing of nanoscale wire arrays using conducting probe atomic force microscopy (AFM) in ambient conditions. A key requirement of this approach is the formation of highly reproducible electrical contacts between the conducting tip and the sample. We discuss the basic mechanical and electrical criteria of nanocontacts and derive a force-controlled protocol for the formation of low-ohmic contacts. Tips sputter coated with platinum provided the mechanical stability for both tapping-mode imaging and the formation of low-ohmic contacts on gold samples. Nanostructures on the sample were identified by topographic imaging and subsequently probed using the AFM tip as a mobile electrode. We measured resistivities in arrays of nanowires or local potentials of wires within electrical circuits, and detected electrical failures, thermal gradients, and small geometrical variations. The ability of this instrument to address electrical characteristics with high spatial resol.
A Simple Nomogram to Predict Contrast-Induced Acute Kidney Injury in Patients with Congestive Heart Failure Undergoing Coronary Angiography

Background Patients with congestive heart failure (CHF) are vulnerable to contrast-induced kidney injury (CI-AKI), but few prediction models are currently available. Therefore, we aimed to establish a simple nomogram for CI-AKI risk assessment for patients with CHF undergoing coronary angiography. Methods A total of 1876 consecutive patients with CHF (defined as New York Heart Association functional class II-IV or Killip class II-IV) were enrolled and randomly (2:1) assigned to a development cohort and a validation cohort. The endpoint was CI-AKI defined as serum creatinine elevation of ≥0.3 mg/dL or 50% from baseline within the first 48–72 hours following the procedure. Predictors for the simple nomogram were selected by multivariable logistic regression with a stepwise approach. The discriminative power was assessed using the area under the receiver operating characteristic (ROC) curve and was compared with the classic Mehran score in the validation cohort. Calibration was assessed using the Hosmer–Lemeshow test and 1000 bootstrap samples. Results The incidence of CI-AKI was 9.06% (170) in the total sample, 8.64% (n = 109) in the development cohort, and 9.92% (n = 61) in the validation cohort (P=0.367). The simple nomogram including four predictors (age, intra-aortic balloon pump, acute myocardial infarction, and chronic kidney disease) demonstrated a similar predictive power as the Mehran score (area under the curve: 0.80 vs. 0.75, P=0.061), as well as a well-fitted calibration curve. Conclusions The present simple nomogram including four predictors is a simple and reliable tool to identify CHF patients at risk of CI-AKI, whereas further external validations are needed.
Speech acts addressed to Hadza infants in Tanzania: Cross-cultural comparison, speaker age, and camp livelihood

This study deals with speech acts addressed to Hadza infants in Tanzania, a group that has traditionally lived off hunting and gathering. Three research questions are addressed: How do Hadza speech acts compare with those found in previous studies in other cultures? Are there differences between child and adult speakers? And do speech acts differ with camp livelihood patterns? Speech acts are seen as a part of language socialization, which reflects overarching cultural values and socialization goals. The results indicate that Hadza infants experience many requests for action/imperatives—a way of expressing hierarchies—more than the infants in the comparative cultural communities, in spite of the fact that hunter–gatherers have been described as egalitarian in the past. Children’s and adults’ speech acts differ in several ways: adults use more requests for action and information (questions) with infants, while children use more assertives. Finally, the comparison of camp livelihoods revealed differences mainly between camps living off tourism and those that are more isolated from outside influence. The former use more imperatives, the latter more vocatives. The results are discussed in terms of cultural change toward more hierarchical structure related to livelihood activities, particularly tourism, and different activities that children and adults engage in when interacting with infants.
Correlation of Excess Energies of Electron‐Impact Dissociations with the Translational Energies of the Products

Translational energies of products of unimolecular dissociations resulting from electron impact have been measured at the appearance potentials of the fragment ions. Excess energies for each process were determined from the measured appearance potentials and the known heats of formation of ground‐state products and reactants. Results are compared with the predictions of the statistical theory and found to be in agreement if the classical density of states is used. Application of the method to accurate determinations of heats of formation of radicals and radical ions is demonstrated.
High‐resolution carbon budgets on a Palau back‐reef modulated by interactions between hydrodynamics and reef metabolism

Diel trends in carbon chemistry and hydrodynamic regimes were measured on a coral‐dominated back‐reef community in the Republic of Palau, western Pacific. Observed diel ranges over 5 d were pH 7.92–8.09, partial pressure of carbon dioxide 33.4–52.7 Pa, measured total alkalinity 2080–2272 µmol kg−1, total dissolved inorganic carbon 1763–1939 µmol kg−1, aragonite saturation state 2.84–3.98, and calcite saturation state 4.44–5.67. The combination of reef metabolism and hydrodynamic regimes drives this variability. We report net community calcification (NCC) and net community production (NCP) rates of −20.4 (± 7.8) to 41.2 (± 37.7) mmol CaCO3 m−2 h−1 and 77.3 (± 95) to 64 (± 22) mmol C m−2 h−1, respectively. Using a control volume approach, we show that NCC and NCP rate estimates are quite sensitive to the effective control volume dimensions. At this site, tracking vertical mixing of water masses within the control volume shows that active water mixing is often confined to a region 2–3 m above the corals. Vertical carbon mass fluxes into and out of the benthic environment were unexpectedly large for the slow current flow rates observed, suggesting that coral morphology or reef rugosity may affect mass transport of carbon and nutrients. The ranges of NCC and NCP values highlight the need for additional field work on various reefs to tune and optimize the control volume approach to achieve its full potential for reef metabolism monitoring.
