Synthesis and Spectral Studies of ZnII,CdII and HgII Complexes with 5-(2-Benzoic acid azo)-8-hydroxy quinoline Ligand
Authors: Journal Baghdad Science
Published: March 2019

Coupling reaction of 2-amino benzoic acid with 8-hydroxy quinoline gave bidentate azo ligand. The prepared ligand has been identified by Microelemental Analysis,1HNMR,FT-IR and UV-Vis spectroscopic techniques. Treatment of the prepared ligand with the following metal ions (ZnII,CdII and HgII) in aqueous ethanol with a 1:2 M:L ratio and at optimum pH, yielded a series of neutral complexes of the general formula [M(L)2]. The prepared complexes have been characterized by using flame atomic absorption, (C.H.N) Analysis, FT-IR and UV-Vis spectroscopic methods as well as conductivity measurements. The nature of the complexes formed were studied following the mole ratio and continuous variation methods, Beer's law obeyed over a concentration range (1× 10-4- 3 × 10-4 M). High molar absorbtivity of the complex solutions have been observed. The stability constant of the complexes has also been studied.

Authors: Journal Baghdad Science
Published: March 2019

The Evaluation of the immune response in Golden Hamsters experimentally infected with Leishmania donovani was determined in this study, particularly, the cellular immune response. Follow up has maintained to determine the Delayed Type of Hypersensitivity using skin test both in infected and control lab animals. Chicken red blood cells were used as a parameter to evaluate the immune system; they are dull and have the ability of immunization. Two concentrations of chicken R.B.C were examined to determine which gives the higher titration in Hamsters and those were 1.5 X 109 cell/ml and 3 X 109 cell/ml , the second concentration gave the maximum titration where then used in this work. After sensitization with Chicken R.B.C for both infected and control groups, delayed type of hypersensitivity has been used against Leishmania donovani antigen and 4 days of follow up were adopted and they were (14, 30, 60, 90) day after infection.
Results showed that skin test against both antigens ( L.donovani and chicken R.B.C) was significantly higher than normal at the first day of follow up ( day 14) then gradual decreasing were noticed till the last day of follow up (90). This can indicate that the infection with L.donovani activated the immune response at the beginning of infection, then leads to cellular immune suppression against both L.donovani antigen and chicken R.B.C., so that this immunosuppression is not specific.

Land Magnetic survey along a profile from Akaz to Rutba town and its applications
Authors: Journal Baghdad Science
Published: March 2019

A land magnetic survey was carried out along regional profile, which is located at the north part of the Iraqi western desert. It starts from al –Qaam City (at north) toward Rutba City (at south) with a total length of 238km. The survey was carried out along the paved road between the two cities, About 113 measuring points were done with inter-station distance of 2 km (for 198 km) and 2 to 5km (for 40km). Two proton magnetometers were used in this survey. One of them is used for base station monitoring, which was fixed as of Salah Aldin field (Akkas). Its readings were used for diurnal corrections. All magnetic measurements were corrected for normal and topographic corrections. The readings were reduced to a certain base level.
The resulted magnetic anomalies show a good correlation with those of Arial - magnetic survey anomalies conducted by (C.G.G, 1974). This is true for those anomalies with wavelength more than 50km. While the land magnetic survey has shown more small anomalies which may reflect near surface sources. In addition, there is a considerable difference between the magnetic intensity values of both surveys. The downward continuation method was used in this study for detecting the depth of magnetic anomaly source. But before applying this method the total magnetic field was converted to its vertical component using computer program packages. The 2.5 mathematical modeling techniques were used for interpreting magnetic anomaly. Several models were suggested according to the geological and geophysical surface and subsurface data. These models clearly suggest that the tectonic of the studied area may be completely affected by deep faults that could reach the basements or even cut it. These faults resulted in tectonic blocks with relative movements that could happen through the geological time, and they may be responsible for the tectonic features of the western desert. These faults could also responsible for the lateral and vertical variations that are noticed in subsurface rocks of the studied area. The subsurface lateral susceptibility variation between the different blocks could result from the variation in physical parameter of the rocks (like porosity, fracture density…) and there is a possibility that rocks beneath 18km (lower crust) still possess some magnetic properties.

Authors: Journal Baghdad Science
Published: March 2019

Plant tissue culture techniques were exploited for the micropropigation of Lisianthus (Eustoma grandiflora). Different concentrations of Benzyl adenine (BA), 6- Furfural amino purine (Kinetin), Indol butyric acid (IBA), were investigated in their effects at different micropropagation stages. Three explants (apical shoots, internodes, leaf discs) were used in this study. The effect of the interaction between BA and IBA on shoot multiplication was investigated in increasing the number of shoots on explants. Rooting was also studied after inclusion of IBA and NAA to Murashige and Skoog, 1962 culture medium (MS). During acclimatization stage, different ratios of river sand and peat moss as agricultural media were tested and plantlets survival was recorded. Maximum mean shoot number was recorded when leaf discs were cultured on MS medium supplemented with 0.3 mg/l of BA giving 6.8 shoots. Highest mean shoot length was obtained when BA at 0.1 mg/l was added to the culture medium giving 1.16 cm. Internodes achieved maximum mean shoot length reached 1.6 cm in the medium supplemented with 0.1 mg/l of BA, while the same concentration of KIN extended the mean shoot length up to 1.6 cm. Shoots that transferred to MS medium containing 1.0 mg/l of IBA achieved the highest root number (5.5) with mean length of 2.5 cm and achieved 70% rooting percentage. Plantlets were acclimatized achieving 90% survival when transferred to agricultural medium consisted of rivers and peat moss at 2:1 v/v ratio.

Published: March 2019

Core Ideas

A noncalibrated PR2 capacitance probe showed significant deviations from actual soil water content.

Calibration improved the accuracy and precision of soil moisture monitoring with the PR2.

Calibration was necessary for using the PR2 probe for research‐quality soil water measurements.

Multi‐depth capacitance sensors are popular to monitor soil water content for scheduling irrigation thanks to their ease of operation and maintenance. The PR2/6 Profile Probe (Delta‐T Devices) measures soil moisture by using either the manufacturer's built‐in equation or a user‐calibrated equation if the soil is high in clay or organic matter. The objectives were to evaluate the performance of the PR2/6 Profile Probe in a perennial grassland and to develop a site‐specific equation to correct probe measurements in Pullman (fine, mixed, superactive, thermic Torrertic Paleustolls) clay loam soils. Permittivity recorded by the profile probe was regressed on the gravimetrically measured soil volumetric water content (VWC). Parameters were optimized to obtain least RMSEs. The default equation provided by the manufacturer estimated VWC with average RMSE and r2 values of 0.053 m3 m–3 and 0.71, respectively. New calibration coefficients were effective in explaining 91% of the variability in soil VWC measurements and reducing RMSE to 0.017 m3 m–3. The results indicate that site‐specific calibration of the capacitance probe is necessary to attain research‐quality accuracy and precision when applied to grasslands in Pullman clay loam and associated clay loam soils.
Effect of Deprivation and Excessive Application of Nitrogen on Nitrogen Use Efficiency‐Related Traits Using Wheat Cultivars, Lines, and Landraces
Authors: Elbasyoni Ibrahim S. , Abdallah Ahmad M. , Morsy Sabah , Baenziger Stephen
Published: March 2019

The International Maize and Wheat Improvement Center (CIMMYT) has identified the wheat (Triticum aestivum L.) irrigated area in the developing countries, which includes Egypt as Mega‐environment 1 (ME1). Agriculture intensification is expected to take place in this region to keep up with a continuously growing population, which might lead to more N application and losses because of the low N use efficiency (NUE) observed in this area. A panel of 40 wheat accessions including 10 commercially grown cultivars (CGCs), 10 elite lines from the CIMMYT, and 20 landraces from Egypt and Ethiopia were evaluated for grain yield (GY), grain protein content (GPC), NUE, agronomic NUE (AGNUE), stem rust, leaf rust, plant height (PH), leaf area, and total chlorophyll content (TCC), under four N levels. The panel was planted in two growing seasons (i.e., 2015–2016 and 2016–2017) and two locations. The results indicated that most of the CGCs were considered N efficient and N responsive. On the other hand, most landraces were N inefficient and nonresponsive because they produced higher GPC, PH, and TCC but had lower GY, AGNUE, and NUE. Furthermore, the landraces were less sensitive to the excessive N supply. ‘Sakha 94’, a commercially grown cultivar, was the most N efficient and N responsive; hence, it produced the highest GY at all N levels. The overall results might be scaled up to cover other Mediterranean basin regions that have similar environmental conditions.
Evaluating the Importance of Barometric Pumping for Subsurface Gas Transport Near an Underground Nuclear Test Site

Published: March 2019

Core Ideas

Gas transport modeling can estimate ground surface breakthrough after an underground nuclear explosion.

Comparison tracer‐injection experimental and model results reveals parameter sensitivity.

Barometric pumping may explain gas breakthrough following an underground nuclear explosion.

Amplitude and period of barometric pressure signal are key in controlling breakthrough.

An underground nuclear explosion (UNE) generates and distributes radioactive gases that can be transported to the ground surface though preexisting and explosion‐induced fractures over timescales of hours to months. If detected, the presence of short‐lived radionuclides in gas is evidence of a recent UNE. Numerical modeling can provide estimates of surface arrival times that can help inform gas monitoring strategies at suspected foreign test sites. Efforts are underway at historic US UNE sites to better understand subsurface gas‐transport processes following a UNE by geologic characterization of the near‐field damage structures, field‐scale tracer experiments, and subsurface air pressure monitoring. The development of numerical models using historical and experimental datasets from former UNE sites can improve predictions by testing conceptual models, highlighting key processes, and constraining parameter ranges. The models developed in this study represent the U20az site at the Nevada National Security Site where the Barnwell device was expended in December 1989. A two‐phase (water and air), dual‐permeability flow and transport model of the U20az site was built to investigate gas transport processes under recent experimental conditions and following the Barnwell nuclear event. Results indicate that the model can explain both the lack of arrival of radioactive gas tracers in a 2013 field experiment as well as the observed arrival of radioactive gases following the 1989 Barnwell event using barometric pressure records from the respective periods, even when additional advective processes associated with the Barnwell detonation are ignored. The results demonstrate that the character of the barometric records may be a key factor in explaining the differences in transport behavior.

Published: March 2019

Core Ideas

The SHAW model was used to simulate the freeze–thaw process during freeze–thaw periods.

It revealed the effects of soil texture and groundwater table depth on soil freezing and thawing.

The frost depth and accumulated negative soil surface temperature relationship was determined.

During freeze–thaw periods, the transformation between phreatic water and soil water will change the soil hydrothermal properties and affect the soil freezing and thawing in shallow groundwater areas. The purpose of this study was to determine the effect of four different groundwater table depths (GTDs) and two soil textures on the process of soil freezing and thawing during two successive freeze–thaw periods using the Simultaneous Heat and Water (SHAW) model. The results show that the frost depth was the maximum when the GTD was 1.0 m, and the maximum frost depths of sandy loam and fine sand were 97.6 and 98.9 cm, respectively. When the GTD was larger than 1.5 m, the maximum frost depth decreased with an increase in GTD, and the maximum frost depth of the soil profile was more sensitive to changes in the air temperature. The frost depth of the soil profile was linear with the square root of the accumulated negative soil surface temperature (ANST) under different GTDs. The ANST was influenced by the phreatic evaporation, and the soil freezing rate increased with an increase in GTD under the same ANST. This research is significant for the rational development of soil water and heat resources and the study of soil water–heat transfer in shallow groundwater areas.
DMRG investigation of constrained models: from quantum dimer and quantum loop ladders to hard-boson and Fibonacci anyon chains
Authors: Chepiga Natalia , Mila Frédéric
Published: March 2019

Motivated by the presence of Ising transitions that take place
entirely in the singlet sector of frustrated spin-1/2 ladders and spin-1
chains, we study two types of effective dimer models on ladders, a
quantum dimer model and a quantum loop model. Building on the
constraints imposed on the dimers, we develop a Density Matrix
Renormalization Group algorithm that takes full advantage of the
relatively small Hilbert space that only grows as Fibonacci number. We
further show that both models can be mapped rigorously onto a hard-boson
model first studied by Fendley, Sengupta and Sachdev [Phys. Rev. B 69,
075106 (2004)], and combining early results with recent results obtained
with the present algorithm on this hard-boson model, we discuss the full
phase diagram of these quantum dimer and quantum loop models, with
special emphasis on the phase transitions. In particular, using
conformal field theory, we fully characterize the Ising transition and
the tricritical Ising end point, with a complete analysis of the
boundary-field correspondence for the tricritical Ising point including
partially polarized edges. Finally, we show that the Fibonacci anyon
chain is exactly equivalent to special critical points of these
models.

El estudio de la adolescencia ha destacado la vulnerabilidad del proceso asociado con variables como la disposición resiliente, presente en aquellos recursos que pueden hacer la diferencia para el sustento del bienestar o su ausencia. De estos recursos se destaca el apoyo social que el adolescente percibe de su entorno. El objetivo de la investigación se centró en establecer la relación entre el apoyo social percibido y la disposición resiliente, y compararlas conforme el sexo y la edad de una muestra de adolescentes paraguayos escolarizados. Se llevó a cabo un diseño comparativo y correlacional, con 1334 adolescentes escolarizados de 12 a 18 años (ME= 14.99; DE= 1.66), 725 mujeres y 609 varones. Se empleó la Escala de Apreciación de Apoyo Social –EAAS y el Inventario de Resiliencia IRES. Los datos evidenciaron que no existe correlación entre apoyo social y disposición resiliente en esta muestra específica de adolescentes paraguayos, por factores que habrá que seguir investigando. Se observan diferencias en el apoyo social de amigos y de otros, mayormente en los varones. En las mujeres, se observan diferencias significativas en las escalas de resiliencia, en el sentido del humor, autoeficiencia y empatía. En cuanto a edad, los adolescentes de 16 a 18 años puntúan más en religiosidad y en el apoyo social, familiar, de amigos y de otros. Se sugiere estudiar otras variables relacionadas con el apoyo social y la disposición resiliente, en tanto muchas de las políticas públicas preventivas de atención a la salud positiva refuerzan su importancia en la adolescencia.

Authors: Finochenko T. A. , Pereverzev I. G. , Balanova M. V.
Published: March 2019

As it is known, load-lifting rail cranes of various models employed as part of Russian Railways repair and recovery trains are high-risk facilities. They normally have large dimensions and powerful engines that generate significant thrust and high energy. The paper examines the effects of harmful occupational factors of physical nature, i.e. industrial noise and vibration on the performance and health of rail crane operators.

Aim. Based on the analysis of the causes of incidents that occurred in the course of operation of rail cranes, generalizing the experimental findings regarding the effects of industrial noise and vibration on crane operators and identifying the correlation between the clinical signs of distress in this category of workers and the levels of the above harmful physical industrial factors.

Methods. Experimental studies and the subsequent evaluation of the effect of industrial noise and vibration generated by the mechanisms of cranes were conducted with the use of an Assistant Total+ noise and vibration analyzer in the course of operation of rail cranes of various models when handling cargo, as well as when crane engines idle. Measurements were conducted at workstations where the operator is to be at during the operation and maintenance of the crane, i.e. the control cabins, operator seat, control handles, near the crane engine.

Results. The paper provides a classification of sources of noise and vibration that affect crane operators, experimental findings regarding the levels of industrial noise, general and local industrial vibration for various models of cranes. Clinical signs of distress are identified, a list is set forth of the most typical occupational health problems for this category of workers.

Conclusions. The paper concludes that the reduction of industrial noise and vibration caused by the mechanisms of rail cranes is a relevant engineering and socioeconomic problem. From the socioeconomic point of view the solution to this problem will allow improving the working conditions of crane operators, while in terms of engineering it will enable higher technical and operational characteristics of crane mechanisms.
Study on the Development of a Cyclohexane Based Tripodal Molecular Device as "OFF-ON-OFF" pH Sensor and Fluorescent Iron Sensor
Authors: Dangi Vijay , Baral Minati , Kanungo B.K.
Published: March 2019

Background:

Iron is an essential transition metal which is indispensable for life processes
like oxygen transport and metabolism, electron transfer etc. However, misregulated iron is responsible
for disease like anemia, hemochromatosis, Alzheimer’s and Parkinson’s disease. In order to encounter
these diseases, a better understanding is needed of its role in misregulation. Fluorescent iron
sensors could help provide this information. The new chemosensor developed by linking a cyclohexane
unit with three 8-hydroxyquinoline provides selective detection of iron in numerous biological
and environmental samples.

Methods:

The Uv-visible and fluorescence spectroscopy in combination with pH measurements will
mainly be used for the study. Theoretical studies at DFT level will be used to validate the method
and explain the theory behind the experiments.

Results:

The study of electronic spectra of the chelator, HQCC, reveals the appearance of a band at
262 nm along with a weak band at 335 nm due to π- π* and n- π* transitions respectively. Upon excitation
with 335 nm, the ligand fluoresces at 388 nm wavelength. The intensity of the emission was
affected in presence of metal ions, with maximum deviation for Fe(III). Selectivity studies showed
that Fe(III) is more selective as compared to the biologically relevant metal ions viz., Al(III), Fe(III),
Cr(III), Co(II), Fe(II), Ni(II), Zn(II), Cu(II), Mn(II) and Pb(II). pH dependent studies implied that the
fluorescence intensity was highest at pH ~8.0, whereas maximum quenching for iron-HQCC system
was observed at pH 7.4. The binding studies from the B-H plot confirms the formation of 1:1 complex
with association constant of 5.95 × 106. The results obtained from experiments were in agreement
with that obtained from the DFT and TD-DFT studies.

Conclusion:

A novel tripodal chelator based on 8-hydroxyquinoline and symmetric cyclohexane
scaffold was successfully developed. In addition to the excellence of the ligand to be employed as a
promising sensitive fluorescent probe for easy detection of Fe3+ions at the physiological pH with
very low concentration (7.5 x 10-5 molL-1), the new ligand can be used as an OFF-ON-OFF pH sensor.
Fe(III) encapsulation along with 1:1 ML-complexation formation have been established. Theoretical
studies confirm a d-PET mechanism for the fluorescence quenching. DFT studies revealed
that the neutral form of the ligand is less reactive than its protonated or the deprotonated form.
Is the Deductive Falsification Approach a Better Basis for Clinical Trial Appraisal?
Authors: Mickenautsch Steffen
Published: March 2019

Background:

Inductive reasoning relies on an infinite regress without sufficient factual
basis and verification is at any time vulnerable to single contrary observation. Thus, appraisal based
on inductive verification, as applied in current clinical trial appraisal scales, checklists or grading
systems, cannot prove or justify trial validity.

Discussion:

Trial appraisal based on deductive falsification can identify invalid trials and give evidence
for the recommendation to exclude these from clinical decision-making. Such appraisal remains
agnostic towards corroborated trials that pass all appraisal criteria. The results of corroborated
trials cannot be considered more robust than falsified trials since nothing within a particular set of
complied trial criteria can give certainty for trial compliance with any other appraisal criterion in future.
A corroborated trial may or may not reflect therapeutic truth and may thus be the basis for clinical
guidance, pending results of any future trial re-appraisal.

Conclusion:

Trial grading following appraisal based on deductive falsification should be binary (0 =
Invalid or 1 = Unclear) and single component scores should be multiplied. Appraisal criteria for the
judgment of trial characteristics require a clear rationale, quantification of such rationale and empirical
evidence concerning the effect of trial characteristics on trial results.

Tamarillo is an underutilized fruit in Indonesia, despite the fact that it contains two pigments (anthocyanin and carotenoid) with different properties (polar and non polar). Besides, there is a scarce information about extraction of anthocyanin and carotenoid of Tamarillo using sonication extraction. This study was aimed to investigate the comparison of extraction methods of sonication with maceration on antioxidant potency of anthocyanin and carotenoid of Tamarillo. Two pigmen types (anthocyanin and carotenoid) were extracted using two different methods (sonication and maceration). The parameters of analysis were yield, antioxidant activity (DPPH) with IC50, Ferric Reducing Antioxidant Power (FRAP), anthocyanin total, carotenoid total, phenolic total and scanning electron microscope of cover cell of material. The antioxidant potencies for both anthocyanin and carotenoid by sonication method were higher than those of obtained by maceration method. The results showed that both sonication and maceration were suitable for extraction of anthocyanin and carotenoid from Tamarillo.

This study was aimed to examine effect of inoculation with Arbuscular Mycorrhizal Fungi (AMF) and intercropping with several mungbean varieties on yield components of red rice grown under aerobic irrigation technique. The experiment was carried out in a pot in the plastic house from June to September 2017. The experiment was designed using Completely Randomized Design with two treatment factors arranged factorially, i.e. AMF inoculation (M0= without, or M1= with AMF inoculation) and mungbean varieties (V) grown together with red rice plant (V1= Kenari, V2= Vima-1, V3= Vima-3, V4= Merak, and V5= No. 129 ). Each treatment combination was made in triplicate. The results indicated that inoculation had a significant effect in increasing filled panicle number, number of filled grains, and dry grain yield per pot, while decreasing percentage number of unfilled grains. For the rice plants incoluated with AMF, intercropping with mungbean of Kenari and Merak varieties produced similar or higher number of filled panicles compared to those without intercropping. In contrast, for the rice plant without inoculation with AMF, intercropping resulted in lower amount of filled panicles than those without intercropping.
Black Country English in the Spotlight: A Stylistic Analysis of Variable Contrast between Phonemes in an Urban Regiolect of British English
Authors: Merry Joel
Published: March 2019

When examining the COT /CAUGHT merger in central Pennsylvania, Labov (1994) uncovered a stylistic phenomenon, known as the “ Bill Peters Effect” , whereby speakers heavily differentiate between /ɑ/ and /ɔː/  in spontaneous speech, but converge the two lexical sets into a near-merger situation during controlled tests comprising isolated minimal pairs. Whilst it is interesting to discover that a speaker or a community of speakers may exhibit stylistic preferences for merging two variants in particular speech contexts, it is unclear as to what precisely drives this intraspeaker and interspeaker variation. By examining the distinctive Black Country variety of English (BCE) (Clark and Asprey 2013), this paper aims to discover if the Bill Peters Effect is specific to the COT /CAUGHT  merger in North American Englishes (Drysdale 1959, Labov 1994, Boberg 2001, Majors 2005, Hall-Lew 2013) or whether it can be observed in merging situations between phonemes in other dialects of English. A study was conducted with 14 native BCE speakers in order to examine in which speech contexts individual speakers distinctly alternate between the FOOT /STRUT  and PRICE /CHOICE  lexical sets and produce merged variants. The normalised F1 distances between each speaker’s realisation of FOOT /STRUT  and PRICE /CHOICE  across three different speech conditions were collected and analysed. The results show that BCE speakers show a stronger preference for merging the lexical sets in a controlled wordlist task, where lexical sets are elicited in isolation, than in less formal spontaneous speech, producing the opposite effect to Labov’s Bill Peters Effect.
Goin’ Home: The Role of Vowel Raising in Indexing an Ethnic Identity
Authors: Ingold Suzey
Published: March 2019

Vowel height can be seen as a feature indexing a particular ethnic identity or indicating a style shift between two such identities. This paper focuses on Bradford-born South Asian musician Zayn Malik, an interesting subject given his prominent status as one of the most influential Asians in Britain today (Parveen 2016). I consider the role of vowel raising in the GOAT lexical set (Wells 1982) over the period of 2010 to 2016 and in style-shifting between casual, interview, and performative styles. The results of my study indicate significant differences in F1 and F2 values between particular years, and differences in F1 values between performative and interview speech. I explore these shifts in relation to the hostility Malik has faced and study the causes of his shifting, particularly in terms of speaker agency and audience design (Bell 1984).
“That’s What It Felt Like, ‘You’re Pathetic’”: Creaky voice, Affective Stance, and Authentication in the Speech of Lady Gaga
Authors: Esposito Lewis
Published: March 2019

This paper contributes to research on the social meaning of creaky voice in American English by offering an intraspeaker analysis of the speech of Lady Gaga, an American pop star. While pop stars have anecdotally been said to employ creaky voice extensively (Jaslow 2011), few linguists have examined the extent of their use, or what they may be using it to achieve. This study, combining statistics, discourse analysis, and media studies, argues that creaky voice has a core indexical meaning linked to “low emotional energy”, and Lady Gaga draws on this meaning to portray herself as “serious” and “downtrodden”.
Working-Class Heroes: Intraspeaker Variation in General Secretary Len McCluskey
Authors: Daw Aïsha , Zhou Xueyan
Published: March 2019

We examine “Liverpool lenition” in the speech of Len McCluskey, a speaker of “Scouse”. Scouse is a variety of Liverpool English associated with the working-class persona of the “Liverpudlian”. We hypothesised that McCluskey, General Secretary of the trade union Unite, would use Scouse relatively more often when speaking to an audience sympathetic to the Labour Party than to an audience that is not. We analysed his rate of lenition in two social settings: speeches to a Labour-sympathetic audience and interviews with a non-Laboursympathetic audience. We find that McCluskey’s spiranisation is more frequent in the speeches than in the interviews. We argue that lenition is a resource for the construction of a working-class persona that may be beneficial for political purposes.
Do People Tweet Like They Speak? A Study of Intraspeaker Variation
Authors: Crawford Naomi
Published: March 2019

This study investigates young female speakers from Scotland to determine to what extent they use Scots dialect features in their written tweets and spoken language. It analyses the production of variation in phonology, morphosyntax, and lexis. The study finds that the speakers’ dialect does appear in their written language, to varying degrees. The analysis presents possible explanations for the variation, including influence from extralinguistic factors such as audience and identity. The study shows a need for further research in this field to widen the scope to encompass different genders and geographical regions.

Published: March 2019

Este artículo se presenta como una reflexión, a partir de una revisión de la literatura sobre la inserción laboral del graduado universitario en España y Latinoamérica; el panorama de globalización, volatilidad económica, aumento de graduados universitarios y otros fenómenos generan dificultad en el acceso al mercado laboral de quienes terminan su paso por la universidad, desde los estudios de segundo ciclo (carrera profesional) hasta tercer ciclo de formación (postgrados). Los resultados encontraron que existen pocos estudios en el área, a pesar de que es en los últimos años donde se han desarrollado, especialmente a finales de la década pasada, así mismo, se detectaron estudios respecto al egresado y a su empleabilidad, analizando básicamente datos estadísticos con los ingresos (tipo de empleo y salario) y, por otra parte, otros estudios que buscan relaciones con la reorganización y los cambios en la educación superior. Como una de las conclusiones más importantes, se tiene que los estudios sobre el tema han detectado las debilidades y fortalezas del recién graduado, así como otros han permitido conocer los requerimientos y puntos de atención en la formación específica que buscan las empresas.
