“¿Conservabas tu carne en cada hueso?”: Sobre las interrogaciones como núcleos de significación en algunos poemas de Ramón López Velarde
Authors:   Universidad Autónoma de San Luis Potosí, Zavala Medina Daniel , Ramírez Israel ,   El Colegio de San Luis, Mexico
Published: March 2022

In this essay, the hypothesis is that some questions can be important nuclei of significance in the poems of López Velarde. To try to verify it, we will conduct a revision of the theoretical approaches on rhetorical questions, both from rhetorical and linguistic standpoints. In particular, we will rely on the ideas of Burguera Serra, Fontanier, Schmidt-Radefeldt, and Igualada Belchí. Based on the above, we will analyze what is asked, how is it asked, why is it asked, what kind of questions they are, and their possible meanings, in some texts of two of his books: La sangre devota (1916) and especially Zozobra (1919).

Background: The approach of suicide and suicide grief in online environments is a reality that goes along with technological advances. Used by their users as spaces for expression, social networks are increasingly being a unique source of information for researchers. In this scenario, Twitter establishes itself as an important object of analysis for understanding the experience on the social network with emphasis on approaches in relation to the themes of suicide and grief, in order to reflect the impacts and implications for the mental health of its users. Aim: Analyze the publications of Brazilian public profiles related to thematic of suicide and grief on social network Twitter. Methods: Retrospective, documentary research with a quantitative approach that analyzed 1.645 Brazilian publications on Twitter using descriptive statistics, association tests and Multiple Logistic Regression Analysis. Results: Publications addressing famous people without comments, shares, or likes predominated. Profiles that expressed suicidal behavior on Twitter were more likely to feature pro-suicidal content in their publications. Conclusions: Twitter is a social network used by its users to discuss suicide and grief, however, with little approach to questions about suicide prevention and prevention. The network stands out for its unique characteristics, on the part of its users and the usability provided, which allows the publication of content and interactions on these topics in a varied and little investigated ways.

Contexto: O Hospital de Alienados do Conde de Ferreira (HACF) foi vanguardista ao nível da assistência aos alienados no final do século XIX, com base nas novas ideias formadas na Europa sobre a psiquiatria e a assistência nesse domínio. Abordar a temática da enfermagem profissional implica tratar uma história iniciada nos anos de oitocentos; falar dos enfermeiros significa aludir a uma presença que sempre existiu nas instituições de saúde, particularmente nas psiquiátricas. Objetivos: Caraterizar o quotidiano no HACF (1883-1885) e analisar as responsabilidades dos enfermeiros nessa instituição. Metodologia: Enquadramento qualitativo, utilizada uma metodologia de investigação histórica, com pesquisa/análise documental e baseada em pressupostos teóricos de Michel Foucault. Resultados: O HACF foi inaugurado a 24 de março de 1883, no Porto. Os seus funcionários pertenciam a três categorias: direção económica, clínica e culto religioso. O corpo de enfermeiros era composto por criados, ajudantes de enfermeiro, enfermeiros e fiscal, pertencendo à direção clínica. Os enfermeiros eram os chefes das enfermarias, sendo responsáveis pelos ajudantes de enfermeiro e criados. Os enfermeiros, ajudantes de enfermeiro e criados deviam zelar pelo equilíbrio dos alienados e pelo seu bem-estar, gerir o quotidiano das enfermarias, aplicar tratamentos e prevenir complicações. Conclusões: Os enfermeiros desempenhavam um papel de vigilância e controle que lhes permitiu a execução de um biopoder no espaço assistencial do HACF. Tinham responsabilidades específicas e pertenciam a uma estrutura hierárquica. Era a eles que os alienados recorriam em primeira instância, na esfera de um quotidiano bem definido.

Authors: Olivero-Verbel Rafael , Johnson-Restrepo Boris , Eljarrat Ethel
Published: March 2022

Concentrations of 19 organophosphate esters (OPEs) were determined in dust samples collected from house and car indoor microenvironments in three Colombian cities. ∑OPE concentrations ranged from 1.31 to 599 μg/g. Mean concentrations of dust homes were 82.6, 48.3, and 46.7 μg/g for Cartagena, Bogotá, and Medellín, respectively. The pollution inside cars was somewhat higher than in houses, with a mean value of 231 μg/g. Sixteen compounds were detected, being TPHP, DCP, TEP, and TCEP the most frequently detected. As for OPEs with higher levels in houses, we found (mean ± SD) 35.2 ± 37.1 μg/g for TDCIPP in Cartagena, 35.6 ± 80.2 μg/g for TPHP in Cartagena, 15.9 ± 31.4 μg/g for DCP in Cartagena, 35.7 ± 19.1 μg/g for TBOEP in Bogotá, 15.7 ± 14.8 μg/g for 4IPPDPP in Medellín, and 17.5 ± 22.9 μg/g for TCEP in Cartagena, while the highest OPE value found in cars was 176 ± 144 μg/g for TDCIPP. The estimated daily intake (EDI) of OPEs through dust ingestion ranged from 0.001 ng/kg bw/day for adults to 110 ng/kg bw/day for toddlers, while dermal absorption ranged from 0.02 ng/kg bw/day for adults to 42.7 ng/kg bw/day for infants. Overall, the EDIs of dust ingestion were three times greater than those of dust dermal absorption. The estimated EDIs were several orders of magnitude below the corresponding reference doses. However, the incremental lifetime cancer risk (ILCR) for TCEP ranged from 1.1 × 10-5 for infants in Bogotá to 4.3 × 10-4 for adults in Cartagena, while ILCR for TEHP ranged from 8.8 × 10-7 for infants in Bogotá to 1.1 × 10-5 for adults in Bogotá. These estimated ILCRs were higher than the safe limit value of 1 × 10-6 and showed that these populations are exposed to moderate cancer risk.
Self-Managed Non-Pharmacological Interventions for Breast Cancer Survivors: Systematic Quality Appraisal and Content Analysis of Clinical Practice Guidelines
Authors: Tan Jing-Yu (Benjamin) , Zhai Jianxia , Wang Tao , Zhou Hong-Juan , Zhao Isabella , Liu Xian-Liang
Published: March 2022

Background: A growing number of clinical practice guidelines (CPGs) with regards to non-pharmacological interventions for breast cancer survivors are available. However, given the limitations in guideline development methodologies and inconsistency of recommendations, it remains uncertain how best to design and implement such non-pharmacological strategies to tailor interventions for breast cancer survivors with varied health conditions, healthcare needs, and preferences. Aim: To critically appraise and summarise available non-pharmacological interventions for symptom management and health promotion that can be self-managed by breast cancer survivors based on the recommendations of the CPGs. Methods: Clinical practice guidelines which were published between January 2016 and September 2021 and described non-pharmacological interventions for breast cancer survivors were systematically searched in six electronic databases, nine relevant guideline databases, and five cancer care society websites. The quality of the included CPGs was assessed by four evaluators using the Appraisal of Guidelines for REsearch and Evaluation, second edition tool. Content analysis was conducted to synthesise the characteristics of the non-pharmacological interventions that were recommended by the included CPGs, such as the intervention’s form, duration and frequency, level of evidence, grade of recommendation, and source of evidence. Results: Fourteen CPGs were identified and analysed. Of the 14 CPGs appraised, only five were rated as high quality. The domain with the highest standardised percentage was “scope and purpose” (84.61%), while the “applicability” domain had the lowest standardised percentage (51.04%). Five guidelines were assessed as “recommended”, seven were rated as “recommended with modifications”, and the remaining two were considered “not recommended”. Regarding the content analysis, physical activity/exercise, meditation, hypnosis, yoga, music therapy, stress management, relaxation, massage, and acupressure were the common self-managed non-pharmacological interventions recommended by the 14 CPGs. Physical activity/exercise was the only self-managed non-pharmacological intervention that was mostly recommended for psychological and physical symptom management by the included CPGs. However, there were significant disparities in terms of level of evidence and grade of recommendation in the included CPGs. Conclusion: The recommendations for the self-managed non-pharmacological interventions were varied and limited among the 14 CPGs, and some were based on medium- and low-quality evidence. More rigorous methods are required to develop high-quality CPGs in order to guide clinicians in offering high-quality and tailored breast cancer survivorship care.

Authors: Salsabila Nais Qonita , Usodo Budi , Subanti Sri
Published: March 2022

Mathematical literacy is defined as students’ capacity to formulate, employ and interpret mathematics in a variety of contexts. It includes reasoning mathematically and using mathematical concepts, procedures, facts and tools to describe, explain and predict phenomena. It assists individuals in recognising the role that mathematics plays in the world and to make the well-founded judgements and decisions needed by constructive, engaged and reflective citizens. Quantity content includes the ability in reasoning quantitatively, representing something into numbers, understanding mathematical steps, counting by heart and making assessments. The questions on quantity content are mostly implemented in everyday life, such as in exchanging currency exchange rates, determining bank interest, shopping, calculating taxes, measuring time, measuring distance and others. The purpose of this article is to describe the level of mathematical literacy ability of junior high school students in solving Quantity content PISA questions. The data from this study were taken from the results of the PISA test questions on quantity content and interviews. Subject taking is based on the test results of students who have the highest scores, as it is expected to get the results of the analysis of students’ high literacy skills. In this research, the researcher is using indicators of mathematical literacy level according to PISA. Based on the results of research and discussion, it is concluded that there are students who have high mathematical literacy skills equivalent to level 5.
Los orígenes del neoestructuralismo latinoamericano
Authors: Mallorquín Suzarte Carlos
Published: March 2022

Este ensayo propone dar cuenta de la ambigüedad del concepto ´neostructuralismo´ cuando se le analiza a partir de la óptica de la obra de Osvaldo Sunkel; no obstante, ello no excluye una posible reconstrucción del término a partir de una reflexión en torno a sus autores “primigenios” y los respectivos vocabularios sobre el ´estructuralismo´. Sin embargo, el concepto ´neostructuralismo´ no armoniza necesariamente con la obra de Sunkel y, paradójicamente, tampoco con la obra de Raúl Prebisch antes del primer lustro de la década de 1970, sino hasta la publicación de la obra “Capitalismo perifé rico, crisis y transformació n”. Por lo tanto, la excursión conceptual que hacemos sobre el ´estructuralismo´ y el ´neostructuralismo´ da a entender que este último es fruto del progreso teórico dentro del pensamiento latinoamericano, bajo la singularidad con que Sunkel se integró al mismo.

Authors: Orozco Plascencia José Manuel
Published: March 2022

En 2016, el congreso mexicano decretó la creación de cuatro Zonas Económicas Especiales (ZEE) en los puertos de Lázaro Cárdenas, Michoacán, Puerto Chiapas, Chiapas, Salina Cruz, Oaxaca, y Coatzacoalcos, Veracruz, cuya transferencia de recursos no será suficiente para superar en el largo plazo la difícil situación socioeconómica de marginación y pobreza que prevalece en la región suroeste de México. En este texto se analizan las ZEE mediante la comparación de información, acciones, beneficios económico-fiscales promovidos por el sector gubernamental y el impacto de dicha política pública para el desarrollo regional. Para una mayor compresión del funcionamiento de las ZEE en México y el mundo, se describirá la experiencia rescatada en 30 años de estudio por el Banco Mundial (BM), particularmente aquella promovida en países asiáticos donde se concentra 90% del empleo de las ZEE.

Authors: Romero Moreno Miguel Ángel
Published: March 2022

La aplicabilidad práctica de los conocimientos teóricos adquiridos durante las clases magistrales constituye una parte esencial en la formación del futuro médico. Sin embargo, las prácticas en quirófanos y en Laboratorios de Cardiología Intervencionista son deficientes. El aforo es limitado por motivos de seguridad. Además, la visibilidad es reducida y la comunicación entre el operador y el alumno puede ser difícil por la presencia del enfermo. Desarrollar un nuevo modelo de prácticas clínicas complementarias a las convencionales ayudaría a que los alumnos adquieran la capacitación básica requerida. El objetivo principal de este proyecto es conseguir que los alumnos obtengan una visión práctica e integral del paciente cardiológico, proporcionando las herramientas necesarias a través de un Aula Multimedia con conexión directa a los Laboratorios de Hemodinámica y a las bases de datos clínicos de la UGC de Cardiología del Hospital Universitario Reina Sofía. Esta acción de Innovación Docente pretende mejorar los procesos de enseñanza-aprendizaje de la Cardiología y realizar una simulación clínica del proceso de diagnóstico, tratamiento y alta hospitalaria de un paciente cardiológico. Adicionalmente, este sistema podría proporcionar al docente una herramienta objetiva para la evaluación de las prácticas clínicas de estudiantes del área de Ciencias de la Salud.

Published: March 2022

El aprendizaje basado en problemas y el aprendizaje colaborativo son metodologías con demostrada eficacia en la docencia universitaria. Permiten trabajar tanto competencias básicas y específicas como transversales: el razonamiento crítico, la capacidad de trabajo en equipo o de toma de decisiones y de liderazgo.

El Grado en Arquitectura y el Grado en Ingeniería de Edificación de la UCAM Universidad Católica de Murcia, puso en práctica el curso 2020-2021 una metodología docente que combina ambos sistemas de aprendizaje, implicando a varias asignaturas de diversas materias, cursos y grados en la resolución del problema, creando un equipo multidisciplinar capaz de analizarlo y solucionarlo.

Se aprovechó el impacto que la pandemia por COVID-19 tuvo en los estudiantes, para proponerles que analizasen las deficiencias que los edificios residenciales en multipropiedad mostraron durante el confinamiento, para establecer protocolos de higienización de los espacios comunes y plantear  alternativas de distribución de las áreas exteriores para uso privativo, mejorando la habitabilidad de los inmuebles y la calidad de vida de sus habitantes.

La experiencia fue sumamente satisfactoria. Se consiguió motivar a los estudiantes, despertar su capacidad de razonamiento crítico y de trabajo en equipo. Aportaron soluciones originales de gran calidad con las que mejoraron sus resultados académicos.

Pedagogical approaches to support student resilience in higher-education settings: A systematic literature review
Authors: Buttazzoni Adrian
Published: March 2022

In recent years, Higher education (HE) students have continued to report rising rates of anxiety, depression and stress. One strategy employed to address these developments has been providing educational and administrative services that help to support and promote student resilience. Efforts to improve student resilience in HE may be bolstered by programs and strategies that go beyond traditional healthcare service delivery: for instance, initiatives such as in-course pedagogical approaches which target enhancing student resilience awareness and understanding. This systematic review aimed to identify, analyze, and synthesize the essential characteristics and programmatic features (e.g., methods) of pedagogical approaches (i.e., teaching strategies, curricula or other features) designed to support resilience among students in HE contexts. Searches were carried out in ERIC, PsychINFO, and SCOPUS and returned 1,545 results. Ultimately, thirty-five articles were included in the final synthesis. A three-level thematic analysis of the included thirty-five articles was conducted, in order to develop rigorous and consistent analytical themes. The five analytical themes that were subsequently developed included: 1) resilience education: reflection, understanding, awareness; 2) individual strategies: personal skill development; 3) institution- or department-level: structural, curricular opportunities; 4) interpersonal strategies: relational skill development; and 5) learning community: cohesion, integration, resource awareness. The implications and effectiveness of these themes for HE instructors are discussed.
Development of modular and accessible teaching labs, incorporating modelling and practical experimentation
Authors: Habtay Yehdego
Published: March 2022

Practical laboratory experimentation has always been a crucial part of engineering education and its effectiveness in facilitating learning is universally acknowledged. Huge advances in computer science, coupled with significant increases in the cost of ever more complex and sophisticated laboratory set-ups, have led to engineering schools’ adopting computer models and simulation software. Although simulation-based laboratory work does enhance the learning experience, it plays a more effective role alongside practical experimentation rather than as a replacement. This case study presents the results and experience gained from an enquiry-based learning of power-converter development laboratory work to support a power electronic converter module at the University of Greenwich. The approach taken allows students to learn the basics of the module through a combination of modelling, simulation and practical experimentation. The modular and portable nature of the laboratory set-ups afforded the students more time and opportunity to explore the subject matter and integrate the laboratory experience with the concepts covered in the lectures. The feedback from students, which was gathered from the students through the university’s EVASYS system, strongly indicated that the approach led to a sustained improvement in students’ learning experience and satisfaction with the module.

El principal objetivo de la investigación es analizar el peso que algunos factores del territorio y la sociedad urbana, como la cercanía, el patrimonio, la imagen o las infraestructuras, tienen en el desarrollo y funcionamiento de los clusters culturales en las ciudades medias y pequeñas. A este fin se ha realizado una aproximación territorial a escala local con una combinación de métodos cuantitativos y cualitativos que se han aplicado a las ciudades españolas de Mérida y Cuenca, elegidas como estudio de caso. Los resultados demuestran que muchos de los parámetros frecuentemente considerados en la bibliografía internacional, y que forman parte de la idiosincrasia de las ciudades medias y pequeñas (cercanía, posibilidad de establecer contactos cara a cara, calidad de vida, bajos costes de producción), son considerados por los entrevistados como indispensables para entender el funcionamiento de sus organizaciones, así como del conjunto de cluster económico cultural urbano. De manera general, estos parámetros aparecen en la bibliografía internacional como coadyuvantes al desarrollo de la economía de la cultural, pero su importancia en las ciudades medias y pequeñas había sido testada en muy pocas ocasiones.

Published: March 2022

Treatment of well flowlines with thermochemical/exothermic fluid has shown good results for wax removal compared with conventional hot oil, hot water, or solvent treatments. However, the technique has not gained widespread use because of the lack of sufficient scientific publications that can give more insights into its use and help in designing a safe and effective treatment. This paper presents a novel transient mathematical model for the design and analysis of thermochemical treatment for well flowlines by accounting for the chemical kinetics, heat transfer, fusion of wax, and associated two-phase flow. The governing equations have been solved using the finite-volume method. The resulting simulator can be used to prepare an optimum thermochemical plan by analyzing the effects of important factors including wax details, deposition profile, heat loss, formulation composition, and injection strategy. Simulation results obtained with the developed model indicate that the entire filling of flowline with thermochemical fluid is not necessary for complete wax removal. Injection of a small thermochemical spacer (TCS) in the flowline followed by its displacement with crude oil can be sufficient in the case of short flowlines of onshore fields. Selection of initial reactant concentration and pH has to be done judiciously based on the maximum allowed temperature in the flowline and the desired extent of chemical utilization. A sensitivity analysis has shown the existence of an optimum range of injection rate below which wax removal efficiency is compromised by excessive heat loss and above which it is reduced by insufficient residence time. The major limitation of this technique is encountered for large flowlines where a possibility of resolidification of removed wax deposits exists because of excessive heat loss. Flowlines of length less than 5 km are found to be ideal candidates as in that case, sufficiently high temperatures can be maintained throughout the journey of TCS in the flowline, which will prevent resolidification.
Innovative Techniques for Optimization of Far-Field Diverter Materials to Enhance Fracture Geometry in Carbonate Reservoirs

The technique of employing specialized particulates for far-field diversion is well established during hydraulic fracturing treatments in unconventional formations and is being investigated for use in conventional formations. Far-field diverters (FFD) divert fluid away from the wellbore far into the formation. The injection of FFD at the beginning of the treatment provides an additional stress barrier between the producing interval and adjacent layers by depositing at the layer boundaries where a higher leakoff is encountered. The ensuing restriction in height growth maximizes fracture extension within the producing zone, optimizing geometry for increased hydrocarbon production while limiting excess water. Polylactic acid (PLA) polymer is self-degradable, compatible with reservoir fluids, and has a variety of compositions for different temperature applications. Blending proppant with PLA has been seen to significantly improve the strength of the deposited FFD. Therefore, PLA powder and silica proppant are blended to develop Generation-1 FFD (FFD-Gen1). However, many silica proppants have greater density than PLA, leading to separation during transport which prevents these two components from depositing evenly at the upper fracture boundary. This results in a situation in which excessive downward growth is prevented while upward growth is left unchecked. For this reason, both components need to be simultaneously deposited to develop an effective seal. Generation-2 FFD (FFD-Gen2) is developed by replacing the silica proppant of FFD-Gen1 with a deformable proppant having a density nearly equal to the polymer, which enables uniform deposition on all adjacent formation boundaries where leakoff is encountered. The deformable characteristic improves the pressure withstanding capacity of the diverter pack.

The deposition and degradation behaviors are investigated in the laboratory by performing high-temperature high-pressure (HTHP) filter press and plug stability experiments. Experimental findings suggest that the primary selection criteria for acceptable performance are the material’s mechanical properties. This methodology is used to select the appropriate FFD materials to optimize fracture geometry in carbonate reservoirs. Successful applications prevent excessive water production and substantially increase hydrocarbon production as illustrated in a three-well case study.
Cleaning Functional Spacer for Improving Sealing Integrity and Zonal Isolation of Cement Sheath in Shale Gas Wells: Laboratory Study and Field Application
Authors: Hao Haiyang
Published: March 2022

Maintaining sealing integrity of cement sheath is essential to oil and gas well completion. The development of large-scale hydraulic fracturing reservoir stimulation technology in recent years has put forward higher requirements for the sealing integrity of cement sheath. For horizontal shale gas wells, it is often necessary to clean the oil-based mud (OBM) before pumping cement slurry to ensure sufficient contact and bonding of cement slurry to casing and formation. Therefore, the removal efficiency of OBM determines the cementation quality of cement slurry with casing and formation.

The present work implements and evaluates a novel cleaning functional spacer (CFS) to overcome OBM removal difficulty through laboratory experiments. CFS consists of weighted spacer (CFS I) and chemical preflush (CFS II). CFS I and CFS II both contain chemical washing agent. OBM removal efficiency test results suggest that with the increase of the concentration of chemical washing agent, the removal efficiency of OBM increases, and the increase of temperature will promote the removal of OBM. Also, it can be found that OBM that sticks to the casing is easier to remove than OBM that sticks to the simulated permeable formations. The water drop on an oil-wet surface gives a contact angle of 66.15°, as nonwetting behavior, while it is reduced to almost zero with the treatment of CFS II on OBM surface. Electrical stability test results show that the demulsification voltages of OBM and CFS II mixture fluids decreased as the percentage of the chemical preflush increased. CFS II will cause demulsification of OBM, reducing the demulsification voltage of the mixture and thus facilitating its removal. The viscosity measurement results demonstrate high compatibility of CFS I with OBM at different volume ratio combinations, which shows its pumpability is safe in field application. The shear bonding strength test indicates that the bonding strength increased by more than 3,212.8% with the use of CFS. Also tight cementation formed at the casing cement sheath interface (CCI), cement sheath formation interface (CFI), and no microannulus appearance. A case history of its use in a shale gas well in the field demonstrates the successful application of CFS to prevent sustained casing pressure (SCP) and maintain the sealing integrity of cement sheath.

Background: Next-generation sequencing (NGS) detects somatic mutations in a high proportion of in plasma cell dyscrasias (PCD), but is so far not integrated into diagnostic routine. We correlated NGS data with degree of bone marrow (BM) involvement by cytomorphology (BMC), histopathology (BMH), and multiparameter flow cytometry (MFC) in 90 PCD patients.Methods: Diagnoses in the 90 patients were multiple myeloma (n=77), MGUS (n=7), AL-amyloidosis (n=4), solitary plasmocytoma (n=2). The NGS panel included 8 genes CCND1, DIS3, EGR1, FAM46C (TENT5C), FGFR3, PRDM1, TP53, TRAF3, and 7 hotspots in BRAF, IDH1, IDH2, IRF4, KRAS, NRAS.Results: Mutations were detected in 64/90 (71%) of cases. KRAS (29%), NRAS (16%) and DIS3 (16%) were most frequently mutated. At least one mutation/sample corresponded to a higher degree of BM involvement with a mean of 11% pathologic PC by MFC (range, 0.002 - 62%), and ~50% (3 - 100%) as defined by both CM and HP. Conclusions: The probability to detect a mutation by NGS in the BM was highest in samples with >10% clonal PC by MFC, or >20% PC by BMC/BMH. We propose further evaluation of these thresholds as a practical cut-off for processing of samples by NGS at initial PCD diagnosis.
Exchange Rate Volatility and the Performance of Manufacturing Sector in Nigeria: An Econometric Analysis
Authors: Onwuka Chinonye Emmanuel
Published: March 2022

This study examined the impact of exchange rate volatility on the performance of manufacturing sector in Nigeria from 1981 to 2020 using ARCH/GARCH model and Autoregressive Distributed Lag Model (ARDL). The ARCH/GARCH model confirms that there is a high exchange rate volatility which was validated by their coefficients which were positive and statistically significant at 1% level. The Augmented Dickey Fuller (ADF) unit root test results showed that all the variables were stationary at first difference and the Bound test confirmed a long run relationship among the variables. The ARDL results show that exchange rate volatility, interest rate and inflation rate has a negative impact on the performance of manufacturing sector in the long run while import and gross capital formation have a positive effect on manufacturing performance in the long run. Also, exchange rate volatility, gross capital formation and interest rate were found to have a significant impact on manufacturing performance while import and inflation were found to be non-significant. The findings also show that in the short run that volatility in exchange rate is negatively and significantly related to the performance of manufacturing sector in Nigeria. Furthermore, the coefficient of error correction term shows that about 66 percent of the disparity between the actual and the equilibrium value of manufacturing performance is corrected every year. The study concludes that monetary authorities should formulate a policy framework that will be targeted at improving and stabilizing naira exchange rate. Also, Nigerian government should appropriate more funds to the manufacturing sector. Finally, interest on lending should be reduced to barest minimal to encourage investment both locally and internationally.
