Authors: Holland Matt , Dutton Michelle , Glover Steve
Published: May 2021

This article explains how to write an effective search plan using simple steps. The article takes you through the tools and techniques that are widely used in major bibliographic databases such as MEDLINE and CINAHL to conduct searches. These include Boolean logic, truncation and wildcards, in-field searching, proximity operators, limits and subject thesauri. Each process is illustrated with an example to help you apply them to your own searches. The process of using these tools and techniques to either narrow (find fewer results) or broaden (find more results) is described and summarised in an easy-to-use table.
Motivation, Temperament, Personality and Well-Being as Predicting Propensity Factors for Mathematical Abilities of Adults
Authors: Baten Elke , Desoete Annemie
Published: May 2021

The role of motivation, temperament, personality and well-being as predicting propensity factors for mathematical abilities was investigated in 30 adults. By embedding these predictors in the Opportunity-Propensity framework, this study aimed to reveal their unique contribution in math development, which is important to improve mathematics education. To our knowledge, the present study is the first to combine predictors and find evidence for the importance of some non-cognitive and socio-emotional propensity factors for mathematical performance by using primary data. Results indicated significant interrelations between the propensities, pleading to integrate them in math research. Furthermore, the relationship propensities and mathematics was dependent on the specific investigated math task, which is in line with the componential nature of mathematics. Negative Affect was the best prediction of accuracy (lower levels of subjective well-being associated with lower levels of mathematical accuracy) whereas Intrinsic Motivation was the best predictor for fact retrieval speed. Limitations and implications for future research are described.

Published: May 2021

The aim of this study was to examine if perceived family violence of victimized children is related to their perceived aggressive behavior. It has been acknowledged that children learn and behave what they observe and practice including violence. A stratified random sample (N =1160) of Omani school students was drawn from grades 6 to 9. The study used perceived family violence and perceived aggressive behavior measures to collect data. CFA was performed to test the proposed factor structure as well as the structural model. The invariance test lent support to the hypothesis that the structure of constructs is invariant across gender. However, the relations between constructs were not invariant. Children (boys and girls) who expressed high verbal violence on them reported they were more verbally and physically aggressive. Boys, but not girls, who reported high physical violence on them reported they were more verbally and physically aggressive. The relation between perceived family violence and perceived aggressive behavior seem to be dependent on gender and types of family violence as well as the kind of children’s aggressive behavior.
ANALYSIS OF MARKETING STRATEGIC PLANNING IN THE HOME FURNITURE INDUSTRY BY APPLYING ANP: A CASE STUDY OF THE IRANIAN HOME FURNITURE INDUSTRY
Authors: Azizi Majid , Mansouri Hamzehali
Published: May 2021

This study was carried out because of the lack of research on strategic planning in Iran's home furniture market. Accordingly, in this study, we developed a decision-making model to select the best solution for strategic planning in the industry. After determining the strategic criteria or factors affecting the developed model, the control criteria of four merits or subsets of competencies were identified. To determine all the effective factors in the model, the sub-criteria of four control criteria and their connections were identified.  The following four possibilities were considered as potential solutions: entrance to a foreign market (S1), increase portfolio (S2), emphasis on scientific management of mixing elements of marketing (S3), and generate research and development units (S4). The Analytic Network Process (ANP) and the Super Decisions software were used to synthesize and analyze the model. It was found that all calculated decisions were influenced by the strategic criteria. A value-weighted competency model was calculated in the first stage with the influence of strategic criteria on the competency model. Hierarchical design decisions were made for each of the competencies and their subsets (144 sub-criteria and 22 middle indices). Paired comparison matrices associated with the degree of the importance of each of the competencies were achieved in the second stage. In the final stage, subsets of the competency weights and their sub-options were identified with the combination of the competencies and the best solution was obtained.

This research aims to develop a model for the implementation of electric ground support equipment (E-GSE) in Indonesia. It employed the qualitative and quantitative method. Data were collected through interviews with airport stakeholders including ground handling, airline and airport experts. The data analysis used the Analytical Network Process (ANP) with Super Decisions software tools. The ANP is a mathematical theory that can be used to analyze the influence of approaches and assumptions used to solve related problems. The key stakeholders from the airlines, ground handling, and airport authority agreed that the critical criteria to implement electric ground support equipment (E-GSE) are emissions standards, pollution sources, limit value, employee exposure, and stationary measurements. The alternative solutions are regulation, company finance, and infrastructure. Those criteria and alternative solutions are in line with the Indonesian government’s regulation, supported by provision of the governor, concerning vehicle tax incentives for electric battery vehicles to support ground handling companies investment in electric ground support equipment (E-GSE) to reduce emissions in airports.

Meta-analysis of variation suggests that embracing variability improves both replicability and generalizability in preclinical research
Authors: Usui Takuji , Macleod Malcolm R. , McCann Sarah K. , Senior Alistair M. , Nakagawa Shinichi
Published: May 2021

The replicability of research results has been a cause of increasing concern to the scientific community. The long-held belief that experimental standardization begets replicability has also been recently challenged, with the observation that the reduction of variability within studies can lead to idiosyncratic, lab-specific results that cannot be replicated. An alternative approach is to, instead, deliberately introduce heterogeneity, known as “heterogenization” of experimental design. Here, we explore a novel perspective in the heterogenization program in a meta-analysis of variability in observed phenotypic outcomes in both control and experimental animal models of ischemic stroke. First, by quantifying interindividual variability across control groups, we illustrate that the amount of heterogeneity in disease state (infarct volume) differs according to methodological approach, for example, in disease induction methods and disease models. We argue that such methods may improve replicability by creating diverse and representative distribution of baseline disease state in the reference group, against which treatment efficacy is assessed. Second, we illustrate how meta-analysis can be used to simultaneously assess efficacy and stability (i.e., mean effect and among-individual variability). We identify treatments that have efficacy and are generalizable to the population level (i.e., low interindividual variability), as well as those where there is high interindividual variability in response; for these, latter treatments translation to a clinical setting may require nuance. We argue that by embracing rather than seeking to minimize variability in phenotypic outcomes, we can motivate the shift toward heterogenization and improve both the replicability and generalizability of preclinical research.

Protected areas are the flagship management tools to secure biodiversity from anthropogenic impacts. However, the extent to which adjacent areas with distinct protection levels host different species numbers and compositions remains uncertain. Here, using reef fishes, European alpine plants, and North American birds, we show that the composition of species in adjacent Strictly Protected, Restricted, and Non-Protected areas is highly dissimilar, whereas the number of species is similar, after controlling for environmental conditions, sample size, and rarity. We find that between 12% and 15% of species are only recorded in Non-Protected areas, suggesting that a non-negligible part of regional biodiversity occurs where human activities are less regulated. For imperiled species, the proportion only recorded in Strictly Protected areas reaches 58% for fishes, 11% for birds, and 7% for plants, highlighting the fundamental and unique role of protected areas and their environmental conditions in biodiversity conservation.
New intergeneric orchid hybrid found in Romania × Pseudorhiza nieschalkii (Senghas) P.F.Hunt nothosubsp. siculorum H.Kertész & N.Anghelescu, 2020

We describe the first reported intergeneric, which naturally occurs between two subspecies belonging to different genera, Dactylorhiza fuchsii subsp. sooana (genus Dactylorhiza) and Pseudorchis albida subsp. tricuspis (genus Pseudorchis), as × Pseudorhiza nieschalkii (Senghas) P.F.Hunt nothosubsp. siculorum H.Kertész & N.Anghelescu, 2020. The hybrid was found and digitally photographed for the first time by Hajnalka Kertész in June, 2020, within Terra Siculorum, in one of the Natura 2000 protected areas, known as Harghita Mădăraș, ROSCI00090. Following detailed morphometric analysis using 67 characters and molecular karyological analyses, we identified this unique specimen as an intergeneric hybrid, new to science. The hybrid, an F1 generation plant, most likely representing a single intergeneric pollination event, is phenotypically intermediate between its parental species in most of the characters scored, but it significantly closely resembles Pseudorchis albida subsp. tricuspis parent. Since several individuals of the parental species occurred in near proximity, within 1–10 meters distance, we suggest that the production of this hybrid required a minimum travel distance of ca 1–10 meters, by the pollinators and frequent exchange of pollen between the parental species was very likely. The parental species and the hybrid, which display a considerable synchronicity in their flowering time, overlap in the pollinator community, sharing various species of Hymenopterans and Dipterans, very abundant in the heathland. This Terra Siculorum hybrid is thus best described as a rarely occurring intergeneric hybrid that shows strong Pseudorchis albida subsp. tricuspis parental dominance in inheritance patterns.
Iron status predicts cognitive test performance of primary school children from Kumasi, Ghana
Authors: Mantey Afua Afreh , Annan Reginald Adjetey , Lutterodt Herman Erick , Twumasi Peter
Published: May 2021

Background

Good nutritional status of school-aged children is crucial in achieving improved cognition. The objective of this study was to assess the relationship between nutritional status and cognition of school-aged children in the Kumasi metropolis, Ghana.

Methods

389 children were selected from ten government-owned schools. Socio-demographic and anthropometric data were collected. Blood samples were collected and analyzed for nutrients levels. Dietary intakes were assessed using food frequency questionnaire and previous day’s nutrients intake. Cognition test was performed using the Ravens Colored Progressive Matrix (RCPM).

Results

Mean age of participants was 8.9±1.4 years, mean RCPM score was 17.9±5.4. More girls scored RCPM below the 40thpercentile (45.5%) than boys (33.7%), while mother’s level of education significantly associated with RCPM percentiles of the children (p = 0.037). Four dietary patterns were generated from food frequency data, and scores of the second pattern, depicting vegetables, non-fruits, bread and cereals, showed a weak negative correlation (r = -0.132, p = 0.026) with previous day’s dietary zinc intake. Cognitive status did not vary by anthropometric and dietary patterns. More anemic (54.4%) than non-anemic (33.3%) children were below the 40thRCPM percentile. Mean previous day’s intake for folate (p<0.001), vitamin B6(p = 0.018), iron (p<0.001), and zinc (p = 0.001) differed significantly between the cognitive test score percentiles of the children. Spearman rank correlation showed weak positive associations between RCPM score and hemoglobin (r = 0.246, p = 0.003) and serum ferritin (r = 0.176, p = 0.036). Binary regression analysis showed anemic children (aOR = 0.4; 95%CI = 0.2–0.8, p = 0.014), compared with non-anemic had decreased odds, while boys, compared with girls had increased odds (aOR = 2.0 95%CI = 1.0–4.0, p = 0.035) for scoring above the 50thRCPM percentile.

Conclusions

Iron status, especially hemoglobin levels, correlated with the cognitive performance of school-aged children in the metropolis. Thus nutritional strategies aimed at reducing iron deficiency anemia are needed.

Authors: Bérard Anick , Sheehy Odile , Zhao Jin-Ping , Vinet Evelyne , Quach Caroline , Kassai Behrouz , Bernatsky Sasha
Published: May 2021

Background

Medications already available to treat other conditions are presently being studied in clinical trials as potential treatments for COVID-19. Given that pregnant women are excluded from these trials, we aimed to investigate their safety when used during pregnancy within a unique population source.

Methods

Using the population-based Quebec Pregnancy Cohort, we identified women who delivered a singleton liveborn (1998–2015). Taking potential confounders into account including indications for use, the risk of prematurity, low birth weight (LBW), small for gestational age (SGA), and major congenital malformation (MCM) associated with COVID-19 repurposed drug use during pregnancy were quantified using generalized estimation equations.

Results

Of the 231,075 eligible pregnancies, 107 were exposed to dexamethasone (0.05%), 31 to interferons (0.01%), 1,398 to heparins (0.60%), 24 to angiotensin-receptor blockers (ARB) (0.01%), 182 to chloroquine (0.08%), 103 to hydroxychloroquine (0.05%), 6,206 to azithromycin (2.70%), 230 to oseltamivir (0.10%), and 114 to HIV medications (0.05%). Adjusting for potential confounders, we observed an increased risk of prematurity related to dexamethasone (aOR 1.92, 95%CI 1.11–3.33; 15 exposed cases), anti-thrombotics (aOR 1.58, 95%CI 1.31–1.91; 177 exposed cases), and HIV medications (aOR 2.04, 95%CI 1.01–4.11; 20 exposed cases) use. An increased risk for LBW associated with anti-thrombotics (aOR 1.72, 95%CI 1.41–2.11; 152 exposed cases), and HIV medications (aOR 2.48, 95%CI 1.25–4.90; 21 exposed cases) use were also found. Gestational exposure to anti-thrombotics (aOR 1.20, 95%CI 1.00–1.44; 176 exposed cases), and HIV medications (aOR 2.61, 95%CI 1.51–4.51; 30 exposed cases) were associated with SGA. First-trimester dexamethasone (aOR 1.66, 95%CI 1.02–2.69; 20 exposed cases) and azithromycin (aOR 1.10, 95%CI 1.02–1.19; 747 exposed cases) exposures were associated with MCM.

Conclusions

Many available medications considered as treatments for COVID-19 are associated with adverse pregnancy outcomes. Caution is warranted when considering these medications during the gestational period.

Published: May 2021

This study aimed to evaluate improvement of tongue-palatal contact patterns during swallowing after orthognathic surgery in mandibular prognathism patients. Thirty patients with mandibular prognathism treated by orthognathic surgery (average age of 27 years, 3 months) and 10 controls (average age 29 years, 6 months) participated in this study. Tongue-palatal contact patterns of patients before and three months after surgery were evaluated by electropalatography (EPG) as well as controls. Whole total of tongue-palatal contact at 0.3, 0.2, and 0.1 sec before complete tongue-palatal contact during swallowing were evaluated. The duration of swallowing phases was also examined. Complete contact of tongue-tip in the alveolar part of individual artificial EPG plate were shown at 0.3, 0.2, and 0.1 sec before complete tongue-palatal contact in the controls, although incomplete contact in the alveolar part were shown at 0.3 sec in mandibular prognathism patients. Whole total of tongue-palatal contact at 0.3 and 0.2 sec before complete tongue-palatal contact was significantly lower in the patients before surgery than in the controls (p<0.05). However, these values increased after surgery. The duration of oral and pharyngeal phase was significantly longer in the patients before surgery than in the controls and the patients after surgery (p<0.01). This study demonstrated that the tongue-palatal contact pattern improved and the duration of oral and pharyngeal phase was shortened in mandibular prognathism patients during swallowing after orthognathic surgery. It is suggested that changes in maxillofacial morphology by orthognathic surgery can induce normal tongue movement during swallowing.

Published: May 2021

Data generated within social media platforms may present a new way to identify individuals who are experiencing mental illness. This study aimed to investigate the associations between linguistic features in individuals’ blog data and their symptoms of depression, generalised anxiety, and suicidal ideation. Individuals who blogged were invited to participate in a longitudinal study in which they completed fortnightly symptom scales for depression and anxiety (PHQ-9, GAD-7) for a period of 36 weeks. Blog data published in the same period was also collected, and linguistic features were analysed using the LIWC tool. Bivariate and multivariate analyses were performed to investigate the correlations between the linguistic features and symptoms between subjects. Multivariate regression models were used to predict longitudinal changes in symptoms within subjects. A total of 153 participants consented to the study. The final sample consisted of the 38 participants who completed the required number of symptom scales and generated blog data during the study period. Between-subject analysis revealed that the linguistic features “tentativeness” and “non-fluencies” were significantly correlated with symptoms of depression and anxiety, but not suicidal thoughts. Within-subject analysis showed no robust correlations between linguistic features and changes in symptoms. The findings may provide evidence of a relationship between some linguistic features in social media data and mental health; however, the study was limited by missing data and other important considerations. The findings also suggest that linguistic features observed at the group level may not generalise to, or be useful for, detecting individual symptom change over time.

Published: May 2021

The multifunctional role of neuron-specific enolase (NSE) in lung diseases is well established. As the lungs are greatly affected in COVID-19, we evaluated serum NSE levels in COVID-19 patients with and without dyspnea. In this study, we evaluated both SARS-CoV-2-infected and uninfected patients aged >18 years who were referred to hospitals in Catanzaro, Italy from March 30 to July 30, 2020. Epidemiological, clinical, and radiological characteristics, treatment, and outcome data were recorded and reviewed by a trained team of physicians. In total, 323 patients (178 men, 55.1% and 145 women, 44.9%) were enrolled; of these, 128 were COVID-19 patients (39.6%) and 195 were control patients (60.4%). Westergren’s method was used to determine erythroid sedimentation rate. A chemiluminescence assay was used for measurement of interleukin-6, procalcitonin, C-reactive protein, and NSE. We detected significantly higher NSE values (P<0.05) in COVID-19 patients than in controls. Interestingly, within the COVID-19 group, we also observed a further significant increase in dyspnea (Dyspnea Scale and Exercise score: 8.2 ± 0.8; scores ranging from 0 to 10, with higher numbers indicating very severe shortness of breath). These data provide the background for further investigations into the potential role of NSE as a clinical marker of COVID-19 progression.
“Don, doff, discard” to “don, doff, decontaminate”—FFR and mask integrity and inactivation of a SARS-CoV-2 surrogate and a norovirus following multiple vaporised hydrogen peroxide-, ultraviolet germicidal irradiation-, and dry heat decontaminations

Published: May 2021

Background

As the SARS-CoV-2 pandemic accelerates, the supply of personal protective equipment remains under strain. To combat shortages, re-use of surgical masks and filtering facepiece respirators has been recommended. Prior decontamination is paramount to the re-use of these typically single-use only items and, without compromising their integrity, must guarantee inactivation of SARS-CoV-2 and other contaminating pathogens.

Aim

We provide information on the effect of time-dependent passive decontamination (infectivity loss over time during room temperature storage in a breathable bag) and evaluate inactivation of a SARS-CoV-2 surrogate and a non-enveloped model virus as well as mask and respirator integrity following active multiple-cycle vaporised hydrogen peroxide (VHP), ultraviolet germicidal irradiation (UVGI), and dry heat (DH) decontamination.

Methods

Masks and respirators, inoculated with infectious porcine respiratory coronavirus or murine norovirus, were submitted to passive decontamination or single or multiple active decontamination cycles; viruses were recovered from sample materials and viral titres were measured via TCID50 assay. In parallel, filtration efficiency tests and breathability tests were performed according to EN standard 14683 and NIOSH regulations.

Results and discussion

Infectious porcine respiratory coronavirus and murine norovirus remained detectable on masks and respirators up to five and seven days of passive decontamination. Single and multiple cycles of VHP-, UVGI-, and DH were shown to not adversely affect bacterial filtration efficiency of masks. Single- and multiple UVGI did not adversely affect respirator filtration efficiency, while VHP and DH induced a decrease in filtration efficiency after one or three decontamination cycles. Multiple cycles of VHP-, UVGI-, and DH slightly decreased airflow resistance of masks but did not adversely affect respirator breathability. VHP and UVGI efficiently inactivated both viruses after five, DH after three, decontamination cycles, permitting demonstration of a loss of infectivity by more than three orders of magnitude. This multi-disciplinal approach provides important information on how often a given PPE item may be safely reused.
Work satisfaction among neuroradiology staff after receiving follow up reports of thrombectomy stroke patients
Authors: Hager Charlotte , Taufik Homan , Blum Friederike , Stockero Andrea , Wiesmann Martin , Reich Arno , May Rebecca , Nikoubashman Omid
Published: May 2021

Background and purpose

During a period of 6 months, we provided our entire neuroradiological staff including physicians, radiographers, and researchers with systematic feedback via email on the further clinical course of stroke patients who underwent mechanical thrombectomy. We analyzed the effects of this feedback on work satisfaction, work meaningfulness and valuation of the therapy among our staff.

Methods

Our staff completed two self-reported questionnaires before and after the period of six months with systematic feedback.

Results

Employees with higher work meaningfulness and higher work satisfaction valuated endovascular stroke therapy as more useful (p<0.001). A good clinical outcome was regarded more motivating than a good interventional outcome (p<0.001). Receiving systematic feedback did not increase work satisfaction (p = 0.318) or work meaningfulness (p = 0.178). Radiographers valuated the usefulness of interventional therapy the worst of all employees (p≤ 0.017). After the feedback period, 75% of radiographers estimated stroke as a more severe disease than before. Also, their desire for feedback decreased significantly (p = 0.007). Primarily patient cases with unfavorable outcomes were remembered by the staff.

Conclusions

Systematic email feedback does not per se enhance work satisfaction or work meaningfulness among employees. However, receiving feedback is educative for the staff. Evaluating work satisfaction and the perception of treatment may help to identify unexpected issues and may therefore help to find specific measures that increase work satisfaction and motivation.
Transformaciones en el paisaje de las cabeceras del Jarama y Manzanares (Madrid). Una aproximación al poblamiento rural de época romana y tardoantigua
Authors: Hernández Sousa José Miguel
Published: May 2021

El presente trabajo pretende ofrecer una visión de la ocupación humana en el piedemonte de la sierra madrileña, en concreto en la cuenca alta de los valles del Jarama y del Manzanares, con una cronología entre la II Edad del Hierro y los inicios de la Alta Edad Media (ss. III a. C.-IX d. C.). Se presenta un análisis de conjunto, diacrónico y comparativo, del poblamiento rural en esta zona serrana y de las dinámicas poblacionales que marcaron su transformación durante la época romana y tardoantigua. Todo ello nos permite, por un lado, trazar la evolución del poblamiento en este territorio, ofreciendo una visión de largo alcance y, por otro, insertar este sector serrano en los procesos que definen este periodo en otras áreas próximas, en especial, en las vecinas tierras salmantinas, segovianas o abulenses. En el mismo el recurso a los SIG (Sistemas de Información Geográfica) se muestran como herramientas imprescindibles en el análisis y explotación de los datos recabados.

The Canadian experience from the perspective of Brazilian immigrant entrepreneurship in Toronto
Authors: Machado Michel Mott , Falcão Roberto Pessoa de Queiroz , Cruz Eduardo Picanço , Hossein Caroline Shenaz
Published: May 2021

Objective: The study aims at analyzing the socio-demographic profile of Brazilian immigrant entrepreneurship in Toronto, its entrepreneurial behavioral traits, in addition to their business profiles. Methodology/approach: This research is multi-method, with qualitative predominance, being exploratory-descriptive. For data-collection it was conducted a survey and further deepening with face-to-face interviews and field observations. Main results: The majority declared themselves to be from the Brazilian Southeast, white, 35 to 49 years old, married, with children, high academic and professional background. The influence of the state of social malaise in Brazil and the official Canadian discourse, seem to act as factors of "expulsion-attraction" to migration. The job condition of unemployment upon immigrants’ arrival can “push” them into necessity-driven entrepreneurship, although there are also ventures that have identified opportunities. Most of the businesses are small and operate in the service sector, concentrated on the West End of Toronto. In many businesses, there was a strong search for identification with the ethnic community itself, which suggests the formation of 'enclave economy', but in some cases, the main market for local consumers was targeted. Theoretical/methodological contributions: The article highlights the importance of conducting a multi-method research to understand possible entrepreneurial configurations by Brazilian immigrants. Relevance / originality: the article has academic relevance given the scarce work on the theme of Brazilian immigrant entrepreneurship overseas. Truly little is known about this phenomenon in Canada. Social and management contributions: The entrepreneurial trajectories described minimize risks for future immigrants; in addition, the discussion about the social capital of the ethnic community allows comparisons with the business of Brazilians in other countries.
NATURAL SWEETENERS AND ITS USE IN PHARMACEUTICAL INDUSTRY
Authors: Majie Ankit
Published: May 2021

Natural sweeteners and artificial sweeteners are the two available sweeteners available for use in pharmaceutical industry. The sweeteners are used as excipients to improve the perception of taste and to mask the bitter taste of some drugs. The use of natural sweeteners is increasing due to their lower toxicity than the artificial ones. Natural sweeteners, especially the non-saccharide sugars are non-toxic, have low calorific value and super sweet (100-10,000 times more sweet than artificial sweeteners). Moreover, they are easily available in nature and can be consumed by the diabetic patients. The secondary metabolite responsible for sweet taste can be grouped under, dihydrochalcones, proteins, polyols, volatile oils, terpenoids, steroidal saponins, etc. They are effective at low concentrations, stable at varying temperature range, non-carcinogenic, compatible with a wide range of drug substance and other excipients in the formulation. In pharmaceutical industry, they are currently used to prepare liquid, oral preparations, prepare the syrup base, employed in coating of pills and tablets and a vehicle for many drugs. The low-calorie value helps to prevent obesity and can be easily consumed by overweight individuals. Most of the natural sweeteners are nutritive so it provides additional nutrition. But, the mixing of natural sweeteners with the substandard artificial ones needs to be controlled.

The cessation clause epitomises the 1951 Refugee Convention’s internal barriers to the full achievement of refugees’ rights. By examining the controversial application of this provision in the case of Rwandan refugees, this paper demonstrates the resultant infringements on refugees’ human rights, and signals a key obstacle in understanding refugee experiences: institutional insistence on subjugating refugee perspectives and knowledge. This top-heavy ‘knowing what’s best’ for refugees must cede to alternative conceptualisations of refugee rights, especially in the well-worn durable solutions debate. A rights-based approach would see transnational mobility as a solution to challenges endured by camp-based refugees in particular. The Rwandan case study is grounded in theories of today’s membership-based nation-state paradigm, and questions whether re-inscribing refugees as primary agents of their own repatriation (with or without return) can bridge the divide inherent in the exclusionary citizenship-centric logic which ultimately structures the refugee rights system, and can adequately address problems rooted in complex identity politics
The Impact of Remittance on Poverty: Evidence from the South African National Income Dynamics Study (NIDS)

The study uses two approaches to assess the impact of remittance on poverty in South Africa. The first approach compares the level of poverty between remittance receiving households and non-receiving households using the FGT index. The second approach uses the logit regression model to estimate how remittance determines the probability of falling into a state of poverty. The findings show that remittance non-receiving households have a higher head count ratio compared to remittance receiving households. The probability of remittance non-receiving households being in a state of poverty is also higher than remittance receiving households. Whereas the poverty gap is higher for remittance receiving households compared to remittance non-receiving households, both groups of households have the same poverty severity level.
El concepto de Estado en España y el Nuevo Reino de Granada: circulación, apropiación y utilidad, 1750-1800
Authors: Sanchez Mejía Hugues Rafael
Published: May 2021

En este artículo indagamos sobre la emergencia del concepto Estado en España y el Nuevo Reino de Granada en la segunda mitad del siglo XVIII. Buscamos dar cuenta de su aparición como novedad de gobierno, presentando primero una arqueología del concepto, clarificando su alcance, uso y otras particularidades inherentes a su aplicación. Por otro lado, a partir del análisis de la obra del misionero capuchino fray Joaquín de Finestrad, quien escribió el texto titulado El Vasallo Instruido, una obra critica de la revolución de los comuneros de 1781, y unos documentos que reposan en el Archivo General de la Nación, pretendemos mostrar la circulación y apropiación de la noción Estado en espacios acotados del Nuevo Reino de Granada. Todo esto para demostrar que la categoría circuló, gracias a diversos actores, estatales o ilustrados, a ambos lados del mundo atlántico, convirtiéndose en una novedad intelectual que tuvo implicaciones prácticas en la vida de los vasallos.
Conflictividad y mediaciones en las parroquias de la diócesis de Santa Marta durante la segunda mitad del siglo XIX
Authors: Santos Delgado Adriana
Published: May 2021

Este texto explora el mundo parroquial de una de las jurisdicciones eclesiásticas del Caribe co- lombiano en la segunda mitad del siglo XIX. Se trata de estudiar la actuación de los curas de la diócesis de Santa Marta en la esfera local durante un período caracterizado por la búsqueda de la consolidación institucional de la Iglesia y por la necesidad de la corporación católica de responder a las reformas secularizadoras de los gobiernos liberales. Específicamente, interesa el examen de la participación del clero en las dinámicas sociales y políticas de las comunidades en donde ejercieron su labor ministerial. Se propone que los funcionarios religiosos desarrollaron formas particulares de intervención en el marco de los contextos de cada parroquia y de sus diversos modos de relacionamiento con los diferentes miembros de las congregaciones a su cargo. El abordaje de estos asuntos se hace a partir del análisis de la experiencia del presbítero Juan Bautista Baldetaro en su paso por varias localidades. El seguimiento a su desempeño revela el protagonismo de los curas en la escena social y la complejidad de las interacciones entre los clérigos, la feligresía, los agentes estatales y las autoridades eclesiásticas.
Repensar identidades y literacidades, reimaginar pedagogías posibles: aportes de miradas desde la transculturalidad y el cosmopolitismo
Authors: Iparraguirre María Sol
Published: May 2021

Literacy Lives in Transcultural Times (2017) es una compilación de estudios en los que se analizan formas de construcción identitaria, a partir de prácticas de literacidad en escenarios socioeducativos actuales, marcados por la transculturalidad, el cosmopolitismo y la descentralización (de medios, de lenguajes, de normas, de culturas). El libro fue editado por Rahat Zaidi y Jennifer Rowsell, ambos de extensa trayectoria en investigaciones sobre diversidad lingüística y cultural, pedagogías multilingües, y prácticas de literacidad y entornos digitales, y prologado por Marjorie Faulstich Orellana. La introducción, escrita por los editores, expone los fundamentos teóricos rectores del libro en su conjunto y los doce capítulos que le siguen presentan trabajos de investigación que comparten la problematización de categorías en gran medida naturalizadas, a partir de estudios de caso.
Escritura e identidad: perspectivas socioculturales
Authors: Atorresi Ana , Eisner Laura
Published: May 2021

A pesar del pronunciado giro identitario experimentado por los estudios socioculturales de la escritura durante los últimos 25 años, los posibles diálogos entre las diferentes tradiciones de investigación han sido poco explorados. Este artículo recorre los principales aportes de las distintas perspectivas que confluyen en el estudio de la escritura y la identidad –los nuevos estudios de literacidad, los estudios con aportes de la psicología sociocultural, la sociolingüística de la escritura y los estudios de multiliteracidades, nuevas literacidades y multimodalidad–, con énfasis en el surgimiento y el desarrollo de las investigaciones que toman este objeto en América Latina; describe y ejemplifica las orientaciones teórico-metodológicas que las investigaciones han seguido hasta el momento y presenta los artículos que componen este número monográfico. El artículo muestra un cuerpo de trabajos en expansión, establece conexiones entre líneas de investigación de diferente procedencia e ilustra nuevos abordajes teóricos y metodológicos que abren nuevas visiones sobre los textos, los procesos de escritura y los escritores al enfocarse en las prácticas que se realizan en contextos socioculturales específicos.
Las identidades y las escrituras en nuestro tiempo
Authors: Quitián Bernal Sandra Patricia , Montoya Castillo Mario
Published: May 2021

Escritura e identidad, título de este número especial de Enunciación, ofrece un recorrido por senderos zigzagueantes y variaciones temáticas en las que se hace visible la importancia y la potencia de la convergencia crítica entre escritura e identidad, espacio en el que emergen desigualdades, diversidad de reivindicaciones, transformaciones y retos de la escritura en la sociedad y la cultura. Esta publicación ilustra con propiedad lo que hoy deba ser, en concreto, un estudio de la escritura y la identidad, el esfuerzo por hacer explícita la comprensión de las escrituras y las identidades que, en gran medida, determinan nuestro tiempo con sus voces, sus textos, sus sentires, sus formas de ser, de pensar y de hacer, es decir, su condición humana. En el fondo, se trata de pensar en las escrituras-identidades situadas en sus variaciones históricas y en sus contextos, pues pensar la convergencia crítica escritura-identidad también es una manera de decir cómo me relaciono conmigo mismo, con el otro y con el mundo. Escritura e identidad es un espacio en el que convergen lo transcultural, lo transfronterizo y lo intersticial.
An Enhanced Solar Hybrid Brayton and Rankine Cycles with Integrated Magnetohydrodynamic Conversion System for Electrical Power Generation
Authors: Ayeleso Ayokunle Oluwaseun , Raji Atanda Kamoru
Published: May 2021

In many developing countries,the use of conventional power plants to generate electricity is not meeting the increasing demands. Therefore, it has become important to find sustainable alternatives. In the present study, a solar hybrid combined cycle power plant consisting of a solar thermal plant, large-scale gas and steam turbines, and a magnetohydrodynamic generator has been investigated under oxy-fuel combustion. The performance analysis of this system under fuel pressure rate varying from 10 to 25 bar was conducted using Cycle Tempo software. The analysis of the gas and steam combined cycle shows that the net powers and the net efficiencies obtained ranged from 98 MWe to 134 MWe and 30.5% to 40%, respectively. In addition, the integration of the magnetohydrodynamic generator to the combined cycle led to an increase in the overall power from 169 MWe to 205 MWe. Moreover, it is seen that the fuel mass rate (2.81 kg/s) obtained in the gas turbine system under oxy-fuel combustion is significantly reduced when compared to conventional systems. The incorporation of solar energy and oxy-fuel combustion in the gas turbine system has increased the combustor inlet and outlet temperature and reduced the fuel consumption. From these observations, the solar hybrid system proposed in this study does not only generates electric power but also reduce the turbine exhaust fumes and CO2 emissions, which is a key factor in minimizing environment pollution.
Talking to Machines: Simulated Dialogue and the Problem with Turing in Jordan Harrison’s Marjorie Prime
Authors: Peters Maria Verena
Published: May 2021

Jordan Harrison’s play Marjorie Prime (Center Theatre Group, LA, 2014), a Pulitzer Prize finalist in 2015, depicts social, medical, and therapeutic interactions between humans and machines. In contrast to other contemporary plays, Harrison’s script does not suggest experimenting with real robots on stage, but follows the traditional approach of having actors pretend that they are machines or, more specifically, projections steered by an artificial intelligence, so-called Primes. The play carefully avoids the “uncanny valley” (Mori) and spares the audience visceral reactions to the machines, instead focusing on philosophical questions about identity, memory, language, and humanness. The article will analyse the use of language as a theatrical code for machineness and explore the implications of language as a criterion for machineness and humanness respectively. Marjorie Prime will be contextualized with the Turing test, especially from the angle of disability studies, to show how the play can be read as a critique of humanism and a plea for posthumanism.
