Published: November 2019

Abstract. As glaciers adjust their size in response to climate variations, long-term changes in meltwater production can be expected, affecting the local availability of water resources. We investigate glacier runoff in the period 1955–2016 in the Maipo River Basin (4 843 km2), semiarid Andes of Chile. The basin contains more than 800 glaciers covering 378 km2 (inventoried in 2000). We model the mass balance and runoff contribution of 26 glaciers with the physically-oriented and fully-distributed TOPKAPI-ETH glacio-hydrological model, and extrapolate the results to the entire basin. TOPKAPI-ETH is run using several glaciological and meteorological datasets, and its results are evaluated against streamflow records, remotely-sensed snow cover and geodetic mass balances for the periods 1955–2000 and 2000–2013. Results show that glacier mass balance had a general decreasing trend as a basin average, but with differences between the main sub-catchments. Glacier volume decreased by one fifth (from 18.6 ± 4.5 to 14.9 ± 2.9 km3). Runoff from the initially glacierized areas was 186 ± 27 mm yr−1 (17 ± 7 % of the total contributions to the basin), but it shows a decreasing sequence of maxima, which can be linked to the interplay between a decrease in precipitation since the 1980s and the reduction of ice melt. If glaciers in the basin were in equilibrium with the climate of the last two decades, their volume would be reduced to 81 ± 38 % of the year 2000 volume, and glacier runoff during dry periods would be 61 ± 24 % of its maximum contribution in the period 1955–2016, considerably decreasing the drought mitigation capacity of the basin.
¿Novohispanos sinistrorsos? Apuntes bibliográficos sobre el estudio del hebreo en la América Latina de la Edad Moderna
Authors: De Prado Plumed Jesús
Published: November 2019

La historia del estudio y el cultivo del hebreo en la América Latina de la Edad Moderna suponen un terreno prácticamente desconocido. A partir de indicios bibliográficos, tanto de impresos como de manuscritos, tanto del uso como del comercio librario en esa época y geografía, pretendemos ofrecer un primer acercamiento sistemático, sin pretender ser exhaustivo, a este ámbito de estudio que, con base en las fuentes disponibles, muchas inéditas, presenta interesantes perspectivas de investigación.
Oriente islámico, esclavitud femenina y matrimonio en el México decimonónico. Una estrategia discursiva
Authors: Palafox Menegazzi Alejandra
Published: November 2019

Mediante el análisis de la Crónica Parlamentaria, publicada paulatinamente por el diputado y escritor liberal Francisco Zarco, este artículo persigue comprobar cómo la contraposición discursiva a una otredad oriental permitió a los miembros del Congreso Constituyente mexicano de 1856 alcanzar determinados objetivos del programa político nacional, relativos a la libertad individual, la indisolubilidad matrimonial y el tratamiento de la tolerancia de cultos. Pone de manifiesto, además, la centralidad que el discurso orientalista tuvo entre las reacciones que los diputados protagonizaron frente un conjunto de representaciones femeninas, contrarias a la implantación del polémico artículo décimo quinto del Proyecto Constitucional, cuestionando la supuesta influencia clerical sobre estas mujeres y evidenciando otros medios de difusión de esta exotizada visión.
Efficient out-of-home activity recognition by complementing GPS data with semantic information
Authors: Natal Igor da Penha , Correia Luís , Garcia Ana Cristina , Fernandes Leandro
Published: November 2019

Smartphones have become an indispensable human device due to their increasing functionalities and decreasing prices. Their embedded sensors, including global positioning system (GPS), have opened opportunities to support human activity recognition, both indoor (in assisted living, for instance) and outdoor. This paper proposes a minimalist activity recognition model for out-of-home environments based on a smartphone. The only sensor used is GPS, whose data is enriched with semantic knowledge extracted online from the Internet, and with brief user’s profile data collected off-line. We conducted an experiment for 20 days with 22 subjects in their day to day life, with identification of 13 selected activities, of which three were performed in movement. Experimental results show that the approach has a high activity recognition performance. This demonstrates that an adequate combination of information with different levels of semantic content can produce an efficient non-invasive solution to monitoring human activity in out-of-home environments.
n. 39 - CONDIÇÕES DE TRABALHO DOCENTE NO BRASIL: ENSAIO SOBRE A DESVALORIZAÇÃO NA EDUCAÇÃO BÁSICA
Authors: Silva Osni Oliveira Noberto da , Miranda Theresinha Guimarães , Bordas Miguel Angel Garcia
Published: November 2019

O objetivo deste artigo foi discutir a desvalorização dos docentes brasileiros, que trabalham na Educação Básica, a partir de uma análise das condições de trabalho docente, os antecedentes históricos, o arcabouço legal e as influências do neoliberalismo nas políticas de estado. O que podemos observar nas discussões com os autores e os dados apresentados é que existe uma defasagem entre o salário dos professores da educação básica no Brasil e a média dos profissionais das outras áreas. Há notáveis avanços na legislação educacional brasileira, com vistas a valorização do magistério e discussões sobre como fazer essa valorização, onde sempre o salário entra na discussão como elemento central. Além disso foi possível inferir que existe uma relação direta entre a qualidade do salário dos professores e sua valorização perante a sociedade, gerando efeitos psicossociais positivos para ele, como satisfação, motivação e consequentemente afetando diretamente na qualidade do trabalho executado e na melhoria da educação de forma geral. Assim, os professores e entidades representativas devem manter a reivindicação da continua valorização profissional perante a sociedade, resgatando o interesse que outrora existia nos jovens em ser professor. Paralelamente é importante que mais textos acadêmicos como este precisam ser produzidos, inclusive com estudos de campo, por se tratar de um tema de extrema relevância para o desenvolvimento de qualquer nação.
How Well Does Undergraduate Education Prepare College Students for the Employment Outlook? A Secondary Data Analysis of Baccalaureate and Beyond Longitudinal Study (B&B)
Authors: Wu Liyun , Lewis Marilyn W.
Published: November 2019

The trajectory of successfully completing an undergraduate educational program, attaining postgraduate employment, and beginning advanced degree programs was examined using the Baccalaureate and Beyond Longitudinal Study (B&B: 2008/2012), a large U.S. nationally representative longitudinal sample survey of college graduates who completed the requirements for a baccalaureate degree. The third cohort of this longitudinal study was used to compare participants’ status at the time of graduation and four years post-graduation. It was hypothesized that graduates whose post baccalaureate employment experiences related to their baccalaureate majors would be more likely to enroll in additional advanced degree studies, and that the post-baccalaureate field of study would be similar to the undergraduate major among those who pursued a graduate degree. Race, gender, disability, and immigration status were entered as control variables. Findings show that within two years, 42.1% of graduates had initiated postsecondary education. These data indicate that graduates were more likely to pursue degrees which were similar to their baccalaureate degree majors. If their bachelor degree majors were health professions, the likelihood that they pursued graduate-level health professional training and related sciences were highest (p<.001). By attending and finishing college, baccalaureate degree recipients heavily invest in their career by using their financial and non-financial resources. College students with fewer resources are less likely to successfully graduate, attain post-graduate employment in their field, and pursue post-baccalaureate studies. Instituting a competency-based curriculum in baccalaureate programs may improve opportunities for students to gain successful employment experiences, increase labor market outcomes, thus narrowing the divide between students with and without financial and non-financial resources.

Published: November 2019

The loss caused by the shoot-fly (Neosilba perezi) was simulated through the elimination of the cassava`s terminal buds, with the objective to quantify this effect towards the roots productivity, flour production and propagative material production (stem cuts). The experimental design was random blocks, with three repetitions, in a factorial scheme with an additional treatment (10 × 4 + 1). Ten damage levels (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) were studied, including a witness treatment (0%). The cassavas were treated during each of the four seasons of the year. The studied variables were: root productivity (t ha-1), flour production (t ha-1) and number of stem cuttings with a diameter greater than 20 and 25 mm. The induced damage in the cassava`s meristem did not significantly affect the root, nor the flour production. However, the stem cuttings production demonstrated a linear decrease in relation to the apical meristem damage level.

Published: November 2019

The advantages of urban and peri-urban agriculture in West African cities, namely its contribution to food production, income generation and resorbing unemployment are well reported. In the peri-urban areas, cropping systems and practices are various and may affect differently soil properties. Those systems and practices may be driven by farms socio-economic conditions. Here we conducted a study in 133 peri-urban farms located at the vicinity of the city of Ouagadougou. Farmers were questioned on their cropping practices and soil samples were taken and analyzed for their total organic C, available P and K contents. Principal component analysis allowed to study the variability of the farms considering cropping systems, the cropping practices and the farms socio-economic conditions. We found that in the studied cropping systems up to 60% of the farms variability was explained. Monoculture led to low soil organic carbon while polyculture led to low soil available K. The studied socio-economic conditions of the farms explained up to 60% of the variability in cropping practices.
The Duffy Blood Group System
Authors: A. Aldarweesh Fatima
Published: November 2019

The Duffy group system includes six known antigens that reside on a glycoprotein which acts as a receptor for chemokines. It is also a receptor for some malaria species. There are significant racial variations in expression of Duffy antigens. Approximately 68% of Blacks lack both Fya and Fyb antigens. Individuals with this unique phenotype are resistant to two malaria species. Antibodies formed against the Duffy antigens are of IgG subclass and are clinically significant as they can be implicated in acute and delayed hemolytic transfusion reactions as well as hemolytic disease of fetus and newborn. Patients who form anti-Fya or anti-Fyb must receive antigen negative blood units in the future.

Authors: Fernandez William , Bontempo Laura , Dezman Zachary
Published: November 2019

A 50-year-old male presented to the emergency department with four days of intermittent chest pain and shortness of breath, which progressively worsened in severity. Testing revealed a troponin I greater than 100 times the upper limit of normal and an electrocardiogram with non-specific findings. This case takes the reader through the differential diagnosis and systematic work-up of the deadly causes of chest pain, ultimately leading to this patient’s diagnosis.
A Case of Central Venous Sinus Thrombosis in a Young Woman
Authors: Delahanty Liam , Parker Timothy
Published: November 2019

Altered mental status is a common symptom in emergency department evaluations and may be present in as many as four to ten percent of patients.1 The etiology can be difficult to determine without significant evidence from laboratory, radiographic and physical examination. The diagnostic approach is largely driven by the provider’s clinical judgment based on the available history. Consequently, less-common diagnoses can be easily missed or delayed if a reasonable suspicion does not exist when considering possible causes. Cerebral venous sinus thrombosis (CVST) is one such uncommon, seldom-considered disease that carries a significant morbidity and mortality. Its clinical presentations vary and it disproportionally affects young to middle-aged individuals. Knowledge of the disease, particularly the risk factors, is key to making the diagnosis. We will discuss the case of a patient who presented with CVST and intraparenchymal hemorrhage in a resource-limited environment.
Occult Vascular Transection Identified by Point-of-care Ultrasound Demonstrating Evidence of Retrograde Flow
Authors: Villarroel Nadia , Wagner William , Schoenfeld Elizabeth
Published: November 2019

Acute vascular injury can be a cause of significant disability and morbidity. High clinical suspicion and a thorough physical examination are key components to facilitate a timely diagnosis. We present a case of acute vascular injury after isolated penetrating trauma. Physical examination demonstrated a strong distal radial pulse; however, point-of-care ultrasound facilitated an evaluation of the directionality of arterial flow, demonstrating that flow was retrograde via the palmar arch. We subsequently identified a proximal and complete arterial laceration.
Retinal Artery and Vein Occlusions Successfully Treated with Hyperbaric Oxygen
Authors: Johnson Daniel , Cooper Jeffrey
Published: November 2019

We present six cases of central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) that we recently treated with hyperbaric oxygen (HBO2). Patients in three of the six cases, including the CRVO case, experienced near to complete restoration of their vision. Another case had marked improvement. Our findings are similar to other case studies with approximately 65-70% improvement in patients treated for CRAO. Physicians should be aware that rapid referral of CRAO and CRVO patients to HBO2 is efficacious. Such patients should be placed on 100% oxygen by non-rebreather mask as soon as the diagnosis is suspected, pending transportation to HBO2.

Authors: Halupa Anthony , Strony Robert , Bulbin David , Kraus Chadd
Published: November 2019

A 71-year-old male presented to the emergency department (ED) for worsening right knee pain for the prior 3-4 weeks. Point-of-care ultrasound (POCUS) of the right knee showed a pseudo-double contour sign. Subsequent ultrasound-guided arthrocentesis of the knee joint was performed, and fluid studies showed the presence of calcium pyrophosphate crystals, which was consistent with pseudogout. Ultrasound for detection of calcium pyrophosphate crystals in pseudogout and chondrocalcinosis has sensitivity of 86.7% and specificity of 96.4% making POCUS a valuable tool for diagnosing crystalline-induced arthropathy in the ED.

Authors: Friedman Matthew , Gollogly Armin , Pena Enrique , Johnson Jennifer , Dulani Tina
Published: November 2019

Iatrogenic aortic dissection (IAD) status-post-cardiac catheterization is a rare complication often isolated to the proximal aorta. This is a case of IAD isolated to the distal aorta in a 41-year-old female who presented to the emergency department with right leg pain after undergoing three cardiac catheterizations. The diagnosis of IAD was made upon discovery of an intimal flap in the distal aorta and femoral artery while performing a point-of-care ultrasound to evaluate for deep vein thrombosis.

Due to the recent increase in endovascular procedures, retained foreign bodies such as stents and catheters in vasculature have become a common and serious complication. Treatments for these complications vary depending on the acuity and stability of the foreign body in the vessel. We discuss a rare case of an adult found to have an incidental retained umbilical artery catheter in the aorta.
Pennies for Your Thoughts: A Case Series of Pancytopenia Due to Zinc-induced Copper Deficiency in the Same Patient
Authors: Dolcourt Bram , Paxton James , Bora Keenan , Aaron Cynthia
Published: November 2019

A 47-year-old schizophrenic male presented on three separate occasions with pancytopenia and sideroblastic anemia due to copper deficiency from massive zinc penny ingestion. The poisoning was treated differently on each visit: intravenous (IV) copper plus surgical decontamination and chelation with calcium disodium versenate (CaNa2EDTA); IV copper plus whole bowel irrigation; and IV copper with surgical decontamination only. Serum zinc half-lives were 80.0 hours, 233.2 hours, and 83.9 hours, respectively. Importantly, chelation with CaNa2EDTA did not significantly alter the elimination half-life. This is the first reported case of the same patient being treated on three different occasions with three different regimens for this condition.

A Rare Case of Hemorrhagic Shock: Morel-Lavallée Lesion
Authors: Claassen Lieke , Franssen Myriam , Robert de Loos Erik
Published: November 2019

Hemorrhage is a major cause of death among trauma patients. Controlling the bleeding is essential but can be difficult when the source of bleeding remains unidentified. We present a 67-year-old healthy male with a hypovolemic shock after a suicide attempt by jumping from a height. Apart from a bilateral pneumothorax with multiple rib fractures, a femur fracture and spine fractures, computer tomography (CT) revealed a closed, degloving injury of the back, also known as a Morel-Lavallée lesion. Hemodynamic instability due to hemorrhage caused by a Morel-Lavallée lesion in the lumbar region is very rare and easily overlooked. This case demonstrates the importance of clinical signs of Morel-Lavallée, and illustrates the need for total body CTs to exclude other locations of bleeding and to detect contrast extravasation. This report also discusses the possible treatment options for Morel-Lavallée lesions.
A Rare Oncologic Emergency: Spontaneous Tumor Lysis Syndrome in Metastatic Colon Adenocarcinoma
Authors: Kalmbach Kathleen , Rahmat Leena , Wos Justyna , Daniel Nicholas
Published: November 2019

Tumor lysis syndrome is an oncologic emergency that can present with variable symptoms and is truly a laboratory-based diagnosis without pathognomonic clinical findings. The classical teaching is to consider this diagnosis in cancer patients undergoing chemotherapy. We present the case of a 66-year-old female with newly diagnosed metastatic liver adenocarcinoma, not on chemotherapy, who was diagnosed with spontaneous tumor lysis syndrome. Cognizance of this syndrome and associated laboratory findings are paramount to diagnosis and rapid intervention.
Arrow to the Chest

Published: November 2019

A 33-year-old male was brought to the emergency department after a penetrating arrow injury to the chest. Initial evaluation revealed the arrow was penetrating the sternum, lung, and aortic arch. Because the patient was in a remote area, timely transfer to a specialized center for definitive operative repair was delayed approximately 24 hours. Treatment was focused on minimizing risk of hemorrhage with tight blood pressure control, while tube thoracostomy was deferred to avoid a change in intrathoracic pressure. The left-sided hemothorax was monitored with serial point-of-care ultrasounds. Ultimately he was successfully transferred and underwent successful surgical intervention.

Colpocephaly Diagnosed in a Neurologically Normal Adult in the Emergency Department
Authors: Parker Christopher , Eilbert Wesley , Meehan Timothy , Colbert Christopher
Published: November 2019

Colpocephaly is a form of congenital ventriculomegaly characterized by enlarged occipital horns of the lateral ventricles with associated neurologic abnormalities. The diagnosis of colpocephaly is typically made in infancy. Its diagnosis in adulthood without associated clinical symptoms is exceptionally rare. We report a case of colpocephaly diagnosed incidentally in an adult without neurologic abnormalities in the emergency department. To our knowledge, this is only the ninth reported case in an asymptomatic adult and the first to be described in the emergency medicine literature.

Published: November 2019

In the face of seemingly insurmountable, persisting problems, what is one thing that you could do to lift that burden in your own space, in your own building, or on your own walls?This defining question led to the creation of Marshall University (MU) Libraries Mental Health Initiative. The initiative began with an art exhibition titled: “Don’t Call Me Crazy: Resiliency through Art.” The goal of this exhibition was to encourage students, faculty, and staff to create artwork informed by mental health or to help process their own mental health. With more than 30 artists and 50 pieces filling the four floors of the library, we used this artwork to launch other aspects of the initiative.
What do you mean? Research in the Age of Machines
Authors: Boston Arthur “A.J.”
Published: November 2019

What Do You Mean?” was an undeniable bop of its era in which Justin Bieber explores the ambiguities of romantic communication. (I pinky promise this will soon make sense for scholarly communication librarians interested in artificial intelligence [AI].) When the single hit airwaves in 2015, there was a meta-debate over what Bieber meant to add to public discourse with lyrics like “What do you mean? Oh, oh, when you nod your head yes, but you wanna say no.” It is unlikely Bieber had consent culture in mind, but the failure of his songwriting team to take into account that some audiences might interpret it that way was ironic, considering the song is all about interpreting signals.

Analysing revisions in online writing
Authors: Haugaard Rikke Hartmann , Dam Jensen Helle
Published: November 2019

New technology has given new insights into the writing process of professional text producers. Keystroke logging can give the researcher knowledge about how text producers write and revise their texts, both at the level of form and content. With a point of departure in the results of Haugaard’s (2016) study of journalistic writing, this article suggests a reassessment of the online revision taxonomy developed by Lindgren/Sullivan (2006b), with a focus on external revisions. In order to be able to interpret the effect of online revisions on the text by means of keystroke logging, it is proposed that revisions be analysed with a point of departure in the semantic content involved, rather than according to location, i.e. in the text already transcribed (contextual revision) or in the text currently being transcribed (pre-contextual revision), as suggested by Lindgren/Sullivan (2006b). It is argued that contextual and pre-contextual revisions should not be conceptualised as dichotomous entities, but as open categories on a continuum of semantically meaningful context, on the basis of which revisions can be interpreted depending on the degree of completeness of the context in which they are made.
Norwegian Business Professionals´ Need for and Use of English as a Business Lingua Franca (BELF) in Multinational Corporations
Authors: Nielsen Tone Holt
Published: November 2019

English is now the corporate language of many multinational corporations (MNCs) worldwide. However, when English is used as a shared language resource, a lingua franca, its use may be both fluid and local, and the characteristics of its local use should then be explored. This article therefore investigates English used as a Business Lingua Franca (BELF) in MNCs in Norway through task-based interviews with Norwegian business professionals about their need for and use of BELF. The findings indicate that business professionals need to use it frequently, and for both routine and more complex tasks, like demanding business meetings. While getting the job done was paramount to all, several associated NS-like ‘correct’ usage with ‘professionalism.’ Their BELF use was characterized by local, ‘company speak’, translingual practices and the accommodation of both non-native (NNS) and native (NS) speakers of English, and the ways in which the latter were accommodated displayed a more positive attitude to these interlocutors than has been found in similar studies. This article argues that English used as a corporate language is a complex phenomenon requiring business professionals to have a wide set of communication resources and the ability to use the language flexibly.
Disseminating and Hiding Information in Technical Communication Courses: The Case of Patents from the Perspectives of Digital Humanities
Authors: Anesa Patrizia , Arina Pellón Ismael
Published: November 2019

Despite their ostensibly aseptic nature, technical texts involve a multifaceted net of institutional, social and pragmatic functions. Patents, in particular, are characterized by a multi-layered rhetorical exercise in which information is provided, and hidden, in light of patent disclosure lawsDrawing on the Cooperative Patent Classification scheme, a corpus of patents related to environmental issues has been compiled. The objective is to investigate the main keywords emerging in the corpus and to analyse their semantic context in this patent type. More specifically, the analysis focuses on the patents’ semantic preference and semantic prosody in order to pinpoint and examine the semantic complexities emerging in this genre and to identify the strategies employed (such as the use of linguistic vagueness) in order to provide the necessary information while not disclosing precious data.

Patents represent a complex, hybrid and cross-disciplinary genre and a finer understanding of their discursive features may contribute to spreading awareness of the importance that semantics plays within the rhetorical pattern of the text. Therefore, they may be fruitfully employed in Technical Communication courses in order to improved reading comprehension and analytical skills.

Injury incidence, characteristics and burden among female sub-elite futsal players: a prospective study with three-year follow-up
Authors: Ruiz-Pérez Iñaki , López-Valenciano Alejandro , Jiménez-Loaisa Alejandro , Elvira Jose L.L. , De Ste Croix Mark , Ayala Francisco
Published: November 2019

The main purpose of the current study was to analyze the injury incidence, characteristics and burden among sub-elite female futsal players. Individual exposure to match play and training, injury incidence and characteristics (player position, injury mechanism, type of injuries, severity of injuries, recurrent vs. new injuries, season variation of injury pattern) in a female futsal team were prospectively recorded for three consecutive seasons (2015–2018). Incidences were calculated per 1,000 h of exposure. A total of 30 injuries were reported during the three seasons within a total exposure of 4,446.1 h. The overall, match and training incidence of injuries were 6.7, 6.4 and 6.8 injuries/1,000 h of exposure, respectively. Most injuries had a non-contact mechanism (93%), with the lower extremity being the most frequently injured anatomical region (5.62 injuries/1,000 h of exposure). The most common type of injury was muscle/tendon (4.9 injuries/1,000 h of exposure) followed by joint (non-bone) and ligament (1.3 injuries/1,000 h of exposure). The injuries with the highest injury burden were those that occurred at the knee (31.9 days loss/1,000 h exposure), followed by quadriceps (15.3 day loss/1,000 h) and hamstring (14.4 day loss/1,000 h) strains. The first few weeks of competition after pre-season and soon after the Christmas break were the time points when most injuries occurred. These data indicate that sub-elite female futsal players are exposed to a substantial risk of sustaining an injury. To reduce overall injury burden, efforts should be directed toward the design, implementation and assessment of preventative measures that target the most common diagnoses, namely, muscle/tendon and ligament injuries.

O trabalho busca relacionar a Teoria da Aprendizagem Significativa com a metodologia de “ensino por microprojetos” como uma possibilidade de introduzir temas de Física na escola pública de Ensino Fundamental. A metodologia pode funcionar como um “organizador prévio” na formação de subsunçores iniciais e uma experiência positiva para gerar predisposição ao estudo da Física. Realizamos dois estudos junto a escolas da rede pública de Porto Alegre, RS, e obtivemos resultados encorajadores próximos de uma aprendizagem significativa. Isto demandaria um acompanhamento de longo prazo e uma análise mais detalhada, mesmo assim os/as professores/as das escolas e os estudantes demonstraram entusiasmo com a experiência. Contudo, a estratégia conseguiu gerar interações nos grupos, incitou a formação de questões de pesquisa e de conceitos físicos introdutórios, e colocou os estudantes no papel de agentes ativos na construção de um plano de pesquisa, promovendo certas reflexões sobre um processo de investigação em Ciências.

Market Integration and Price Movement of White and Brown Cowpea in Urban and Rural Markets of Gombe State, Nigeria: A Granger - Causality Approach
Authors: Iroegbute U. K. , Mohammed I. , Jibril S. A. , Panwal E. F. , Moses J.
Published: November 2019

The study investigated the price movement and market integration of rural and urban price of brown and white cowpea in Gombe State, Nigeria. Monthly market prices (measured in Naira per kilogram) of brown and white cowpea in the rural and urban markets from January 2009 to December 2014. The data was obtained from the Gombe State Agricultural Development Programme (GSADP). Augmented Dickey Fuller test was used to detect for the presence of unit root in the series. The Granger causality test was used to test the direction of influence between prices.The descriptive statistics shows that the average price of rural brown cowpea was ₦109.88k, rural price of white was ₦95.71k, urban price of brown was ₦ 123.18k while urban price of white was ₦ 110. Unit root test indicated that the prices were stationary at level I(0) and first difference I(1). The Johansen co- integration analysis was used to test for the relationship between markets price and the results indicated that the rural and urban markets price were co- integrated. Pair-wise granger causality test indicated a bi-directional movement between the urban price of brown and urban price of white and a uni-directional movement between rural price of white cowpea and rural price of brown cowpea. There is need for the State government to establish market information centers and information centre of the GSADP should facilitate efficient communication and flow of information concerning prices of agricultural products using the mass media and social media.

Print empowers ways of communicating an idea. In fact, in many ways, it could promote democratization of an individual’s expression, which sometimes can be uncontrollable and even anarchic. Though printing has powerful impact on society; it has been ignored in mainstream scholarship. Existing studies about printing press and its impact on the Malay world are limited. It is surprisingly marginalized in the mainstream scholarship despite the fact that history actually bears witness that printing played an important role in the past. Thus, this article discusses the print culture in the Malay world with special reference to the Kingdom of Riau-Lingga. It begins by describing the techniques of printing especially lithography and typography used in the Malay world.  It also explains the advent of the print technology in the Dutch East Indies in general and Riau in particular, and how the print culture gradually replaced manuscript in knowledge transmission during the time of Raja Ali Haji. Subsequently, it describes how the Rushdiah Club utilized this technology during the end of the 19th century in Riau-Lingga.

The large demand for drinking water in Gbêkê region of Côte d’Ivoire is supplied from groundwater sources. This study investigated the groundwater physicochemical quality in Gbêkê region of Côte d’Ivoire based on preselected 24 boreholes. Groundwater evaluation index and focused principal components analysis were used to assess water physicochemical quality, which is a major factor for controlling the groundwater quality in term of drinking purposes. Most of the groundwater were acidic and presented low mineralization. Hydrochemical facies was Mg-Ca-Cl type. Groundwater quality index values ranged from 11.69 to 119.37. The analysis shows that about 96% of the samples were belonging to excellent quality water for drinking purposes. Focused principal components analysis suggests that groundwater quality was mainly related to geogenic (rock–water interaction) and anthropogenic source (agrogenic and domestic sewage) in the study area. It is expected that outcomes of the study will provide insights for decision makers taking proper measures for groundwater quality management in central Côte d'Ivoire.

Self-medication is very common especially in developing countries and is documented to be associated with many health risks including antibiotic resistance. Antibiotic resistance is shrinking the range of effective antibiotics and is currently listed as a global health problem. This study investigated the perceptions of self-medication with antimicrobials (SMWA) after community mobilization intervention among the households in Nyalenda B, an informal settlement, within Kisumu County, Kenya. This enabled the study to establish the magnitude of SMWA and the perceptions that persist given such intervention within the region. Data was collected through structured questionnaires administered to 380 households. Focus group discussions (FGDs) were also facilitated and targeted purposively-selected 30 CHVs.  Descriptive and binary logistic regression analyses were used to determine the association between socio-demographic characteristics and the perceptions influencing SMWA. The study established that 316 households had used antimicrobials of which 20.9% were self-medicating with antimicrobials. Age (OR=0.647, 95% CI=0.431, 0.973, P=0.037) is significantly related to SMWA, use of NHIF for outpatient services (OR=1.772, 95% CI=0.652, 2.887, P=0.133) and use of Universal Healthcare Services (OR=1.165, 95% CI=0.922, 1.472, P=0.201) may have contributed to SMWA reduction but not significantly as compared to other socio-demographic factors. Likewise, sources of information or advice on self-medication (OR=0.732, 95% CI=0.613, 0.873, P=0.001) and illness or symptoms of illness (OR=1.324, 95% CI=1.129, 1.554, P=0.001) may significantly influence SMWA as compared to other SMWA perceptions. Community mobilization using empowerment as a strategy and implemented through participatory learning and action is a successful method for reduction of SMWA level and development of SMWA perceptions with an experiential value especially when strengthened with structural modification. SMWA is a serious problem in developing countries and so such intervention should be prolonged and continuous to offer sustained changes in public perception and attitudes towards the misuse of antimicrobials.

Perpetration of Adolescent Dating Violence: Child Abuse, Attitudes, Impulsivity, Reactive and Proactive Aggression; Automatic or Complex Processes?
Authors: Sánchez Paulina A. , Varela Jorge J. , Ceric Francisco , Cruz Ana Rita
Published: December 2024

Adolescent dating violence (ADV) research has neglected the environmental factors at play in contexts of perpetration. This study, conducted in Chile, investigated the socio‐cognitive processes inherent to the relationship between child abuse and ADV perpetration by examining the association between child abuse, impulsivity, reactive aggression, proactive aggression, attitudes that rationalize or justify ADV, and actual ADV perpetration. Data were collected from 655 adolescents using self‐reported measures of child abuse, impulsivity, reactive and proactive aggression, attitudes justifying ADV, and ADV perpetration using structural equation modeling. Having experienced child abuse predicted higher levels of impulsivity, which in turn predicted higher levels of aggressive traits, both for reactive and proactive aggression. Proactive aggression predicted higher levels of ADV perpetration, whereas reactive aggression did not. While we did not find that child abuse predicted a greater propensity for ADV, nor that such a disposition indicated a higher level of proactive aggression by influencing ADV perpetration, we did find that a positive attitude toward ADV predicted a higher frequency of ADV perpetration. Our results suggest that the socio‐cognitive process underlying ADV involves automatic and complex processes stemming from child abuse, thus linking environmental and individual factors.

This paper focuses on designing and producing a hybrid metamaterial with a relative density of at least 0.59 using additive manufacturing. The metamaterial consists of layers of four‐star (A) and honeycomb (B)‐shaped unit cells. Three configurations (ABA, AABAA, and AABB) were 3D printed at various layer heights (0.06, 0.10, 0.15, and 0.20 mm). The quality of the printed samples depends on the layer height, with lower heights producing fewer defects and better geometric accuracy. In‐plane compression tests were conducted to evaluate the mechanical properties. The stress‐strain curves exhibited linear plateau and densification regions, varying across designs and layer heights. The AABB structure, printed at 0.1 and 0.06‐mm layer heights, showed the highest peak stress, while the ABA structure exhibited the lowest stress. The AABB structure, with a density of 742 kg/m³, demonstrated the potential for large deformation applications. Visual examination revealed distinct distortion patterns in the unit cells during loading, with the honeycomb cells in the ABA structure experiencing the most significant shape distortion. Overall, this research highlights the potential of hybrid metamaterials for lightweight and large deformation applications. The optimal design and manufacturing parameters can be tailored to achieve specific mechanical properties and performance requirements.

As data volume and complexity increase, conventional software‐based encryption methods face significant challenges, including vulnerability to attacks and high computational demands. This study proposes a hardware‐based cryptographic engine using a dual‐polarity memristive crossbar array with Ta/HfO2/RuO2 memristors, utilizing stochastic and deterministic operations for enhanced security and efficiency. The system integrates random key generation and XOR‐based logic operations within the memristive array, enabling robust encryption and decryption of binary data with a fully resistive data representation. Experimental validation of alphabet image data encryption and the array scale simulation of individual fingerprint authentication are conducted to validate the robustness of the proposed hardware and cryptographic method. The results demonstrate the potential of the proposed hardware for homomorphic encryption, enabling secure data processing without decryption, which can pave the way for memristive hardware to evolve into resistance‐based digital computing hardware.

Electrosynthesis of hydrogen peroxide (H2O2) by two‐electron oxygen reduction reaction (2e− ORR) under acidic conditions is promising. However, constructing a highly efficient acid‐resistant 2e− ORR electrocatalyst is critical but challenging. Herein, a coaxial cobalt single‐atom catalyst on carbon nanotubes (CoSA‐N‐C/CNTs) is designed and synthesized by an ingenious separation chemical vapor deposition (SCVD) strategy, which achieves higher ORR activity, dominated 2e− selectivity, and superior stability in acid, compared to the counterpart nanoparticle catalyst prepared by traditional mixture pyrolysis. The as‐assembled electrode using CoSA‐N‐C/CNTs catalyst demonstrates a high H2O2 yield in excess of 2000 mmol gcat−1 h−1 with a Faraday efficiency of >90% over 100 h without decay in a flow cell, as superior to the most reported acidic H2O2 production catalysts. Experimental characterization and theoretical calculations reveal that such excellent 2e− ORR performance of CoSA‐N‐C/CNTs originate from the combined advantages of strongly coupled coaxial core–shell structure and highly dispersed single‐atom property. Most importantly, a series of other coaxial transition metal single‐atom catalysts (MSA‐N‐C/CNTs, M = Fe, Cu, or Ni) are prepared through this SCVD strategy, and they all show enhanced ORR performance, demonstrating universality.
