Religious Self-definition, Mass Attendance, Importance of God, and Hopelessness among Spanish Undergraduates
Authors: García-Alandete Joaquín , Martínez Eva Rosa , Gallego-Pérez José Francisco
Published: September 2021

The aim of this work was to examine the relationship between religious self-definition, attending Mass, the importance of God, and hopelessness under the hy-pothesis that these religious variables and hopelessness are negatively related. The participants were 273 Spanish undergraduates who were incidentally recruited. and who completed three religious items and the Spanish version of a Hopelessness Scale. The Chisquared test and Bonferroni test were used in the statistical analysis. The results indicate that there were no statistically significant differences between the reli-gious self-definition and attending Mass groups in relation to hopelessness, whereas there were differences between groups in the variable importance of God; this is not consistent with the findings of previous studies. We discuss the limitations of the study, offer suggestions for future research, and indicate the need to distinguish between the diverse aspects of religiosity to better explain their implications regarding hopelessness.
Puntos de inflexión y recuperación del desarrollo infantil tras experiencias iniciales de adversidad
Authors: Muñoz Silva Alicia
Published: September 2021

El presente trabajo analiza la capacidad de recuperación del desarrollo infantil a partir de la revisión de los resultados obtenidos por diferentes investigaciones que han examinado las trayectorias evolutivas de niños y niñas con experiencias iniciales muy adversas pero que, gracias a factores de diversa índole, pudieron experimentar un punto de inflexión en sus vidas. Tras la exposición de los estudios y sus principales hallazgos, se reflexiona sobre su contribución a la compresión de las posibilidades de recuperación del desarrollo infantil y el alcance y limitaciones de la intervención con niños y niñas expuestos a situaciones de riesgo o adversidad.

Authors: Canto Ortiz Jesús María , Moreno Jiménez Pilar , Perles Novas Fabiola , San Martín García Jesús
Published: September 2021

En esta investigación han participado 170 estudiantes universitarios (80 hombres y 90 mujeres). El propósito de este trabajo fue analizar si la cultura del honor, el sexismo y el grado de celos influían en el tipo de infidelidad (sexual o emocional) que más afectaba a los sujetos. Los participantes respondieron a seis dilemas en los que se les planteaban el tipo de infidelidad que más les afectan (sexual o emocional), una escala sobre escala sobre cultura del honor, un inventario sobre sexismo y una escala sobre celos. Los resultados mostraron diferencias entre hombres y mujeres sólo en dos de los seis dilemas. Se analizó la influencia de la cultura del honor, del sexismo hostil, del sexismo benévolo y del grado de celos en la preocupación por la infidelidad sexual y la infidelidad emocional. Se obtuvo que las mujeres que se preocupaban más por la infidelidad sexual puntuaron más alto en cultura del honor, sexismo benévolo y celos.
Resiliencia psicológica y dolor crónico
Authors: Ruiz Párraga Gema Teresa , López Martínez Alicia Eva
Published: September 2021

El estudio de la resiliencia ha adquirido un marcado protagonismo en la actualidad, aun tratándose de un ámbito con una larga trayectoria. Sin embargo, no existe una definición unánimemente aceptada sobre la misma, a pesar de su indudable relevancia en el campo de la salud. En este marco, se está comenzando a prestar atención al papel que la resiliencia desempeña en la adaptación a la patología física, como la representada por el dolor crónico. Los escasos estudios efectuados hasta ahora en este contexto la muestran como una variable ciertamente relevante en la adaptación al dolor crónico. Sin embargo, las diferencias en la conceptuación y medición de la misma no permiten extraer conclusiones definitivas, lo que hace necesario seguir realizando investigaciones en esta área.
Preocupación por la apariencia física y alteraciones emocionales en mujeres con trastornos alimentarios con autoestima baja
Authors: Asuero Fernández Ruth , Avargues Navarro María Luisa , Martín Monzón Beatriz , Borda Mas Mercedes
Published: September 2021

El objetivo del presente estudio fue investigar las diferencias de edad, estado nutricional (Índice de Masa Corporal o IMC), ansiedad, depresión e insatisfacción corporal en pacientes con trastornos de la conducta alimentaria (TCA.), con una autoestima baja, media y alta. Además, intentamos distinguir las discrepancias entre el estado nutricional real y el estado nutricional deseado. Se evaluaron un total de 146 mujeres con TCA (Anorexia nerviosa y Bulimia nerviosa según el DSM-IV-TR). Los cuestionarios utilizados fueron el Body Shape Questionnaire (BSQ), el Hospital Anxiety and Depression Scale (HADS) y la Rosenberg Self-Esteem Scale (RSES). Los resultados reflejan diferencias significativas entre los tres subtipos de pacientes de baja, media y alta autoestima en cuanto a la ansiedad, depresión, insatisfacción corporal, IMC deseado y la relación dentro de IMC real y el IMC deseado. Estos hallazgos indican que las mujeres de baja autoestima presentan altos niveles en insatisfacción corporal, ansiedad y depresión en comparación con los otros grupos. Además, los pacientes con TCA con baja autoestima mostraban un mayor IMC deseado. Sugerimos que se incluyan técnicas de autoestima en la prevención y el tratamiento relacionados con programas de TCA para disminuir los síntomas de ansiedad y depresión.

Authors: García Jerónimo , Bernal Ainara , Lara Alejandro , Galán Pablo
Published: September 2021

En la actualidad es patente el aumento de la población mayor en los servicios deportivos, lo cual hace necesario la evaluación de la percepción de calidad debido a su repercusión sobre la fidelidad. Por esta razón, los objetivos de este trabajo fueron conocer la percepción de calidad y la fidelidad en clientes mayores de 55 años en centros de fitness públicos. Analizar si existen diferencias significativas en la percepción de calidad de este grupo de población. Y, examinar si la calidad percibida incide en la fidelidad de estos clientes. Para ello se utilizó una muestra compuesta por 610 usuarios de centros de fitness públicos (406 mujeres y 204 hombres), realizándose un análisis factorial exploratorio, análisis de la fiabilidad, prueba t y ANOVA de un factor, y regresiones lineales. Los resultados muestran escalas fiables y válidas de calidad percibida de servicio (empleados, programas e instalaciones) y fidelidad, así como la existencia de diferencias significativas en las dimensiones de empleados e instalaciones en cuanto al género, edad y formación académica, y en la dimensión de programas en el género, formación académica, estado civil y duración de la sesión de práctica. Igualmente se constató la influencia positiva entre calidad percibida y fidelidad del cliente. Estos hallazgos sugieren la importancia de una buena gestión de la calidad.

El objetivo de este estudio fue establecer, en una muestra de población afectada de diabetes mellitus tipo 2, la relación existente entre la calidad de vida relacionada con la salud y nivel de actividad física y el ritmo, frecuencia y tiempo que es aconsejada por parte de profesionales sanitarios. Se usó un diseño de corte trasversal-observacional en el que participaron 104 sujetos afectados por diabetes mellitus tipo 2. Se evaluó la calidad de vida relacionada con la salud, el nivel de actividad física y ritmo, frecuencia y tiempo de actividad física aconsejada por el profesional sanitario (cuestionario de creación propia). Se observaron diferencias en la calidad de vida relacionada con la salud (p < .05), y sobre la cantidad de actividad física (p < .05) en función del ritmo, frecuencia y tiempo con la que se aconsejaba el ejercicio físico. Los resultados observados establecen la importancia que los canales de información pueden tener sobre la adquisición de hábitos de vida activos y saludables por parte de pacientes afectados por diabetes mellitus tipo 2. Además resalta la necesidad de que el profesional sanitario que maneja a pacientes diabéticos debe estar capacitado trabajar de manera multidisciplinar con profesionales de actividad física, ayudando en este sentido al control y al manejo de la enfermedad, mejorando la calidad de vida relacionada con la salud de quienes la padecen.
¿Previene la actividad física y mental el deterioro cognitivo? Evidencia de la investigación animal
Authors: Sampedro-Piquero Patricia , Begega Azucena
Published: September 2021

En las últimas décadas se han desarrollado varias estrategias farmacológicas para prevenir el declive cognitivo en el envejecimiento, sin embargo la inefectividad de la mayoría de ellas ha hecho que las intervenciones conductuales estén recibiendo cada vez más atención. La estimulación cognitiva y la actividad física han mostrado importantes beneficios al reducir las alteraciones cognitivas relacionadas con la edad y la demencia. Gracias a los modelos animales cada vez se sabe más acerca de los mecanismos neurobiológicos que subyacen a la reserva cognitiva y cerebral que promueven estas intervenciones. En esta revisión presentaremos varias investigaciones en roedores viejos en las que se muestran los efectos positivos del enriquecimiento ambiental y ejercicio aeróbico sobre la función cerebral y cognitiva de estos animales. La implicación de estas investigaciones para el envejecimiento humano será también discutida.
Conocimientos clínicos y proceso de evaluación
Authors: Godoy Antonio
Published: September 2021

Se presentan tres modelos teóricos acerca del proceso diagnóstico y la forma en que se organizan los conocimienros en la memoria del clínico. Estos modelos son el de Berrios y Chen, que concibe la organización de los conocimientos como redes neuronales artificiales; el modelo semántico estructural de Lemieux y Bordage, que propone como principio estrucrurador de los conocimientos el concepto de eje semántico; y el de Schmidt y Boshuizen, que propone el concepto de guión de enfermedad. Tras ello, se expone la imbricación de cada modelo en la psicología básica, los pasos que propone para el proceso diagnóstico, cómo se organizan los conocimientos en memoria y cómo se recuperan de la misma al aplicarlos a la solución de casos clínicos particulares, qué criterios utiliza el clínico para juzgar si un determinado dato empírico es relevante y debe ser recogido y, por último, la posible utilidad que tiene cada modelo para la enseñanza del psicodiagnóstico (i.e., evaluación en psicología clínica).

Lo que he aprendido tras 40 años de investigación en personalidad
Authors:  Epstein Seymour
Published: September 2021

Durante los más o menos 40 años en que he realizado investigación sobre personalidad, he tenido diferentes oportunidades de reflexionar acerca del proceso de investigación que, según creo, merece la pena compartir: el reconocimiento del aspecto humano de la ciencia; algunas lecciones procedentes del debate persona-situación; lecciones aprendidas al comparar la investigación en situaciones naturales de alta implicación personal, como el paracaidismo, con sus análogos de laboratorio; el reconocimiento de lo que es erróneo en el concepto freudiano de inconsciente y lo que debería hacerse para reemplazarlo y la conciencia de sesgos en el proceso de revisión de las revistas. Quizás la lección más general que he aprendido es que el avance de la Psicología como una ciencia acumulativa e integradora queda limitado no tanto por su complejidad conceptual, como por la dificultad de los humanos para observarse a sí mismos con objetividad, honestidad, coraje y con el deseo de evitar falsas ilusiones.
Perspectivas recientes en el estudio de la motivación. La teoría de la orientación de la meta
Authors: De la Fuente Arias Jesús
Published: September 2021

Los estudios sobre la motivación académica desde la perspectiva de la orientación de las metas han tenido gran protagonismo en los últimos años. Sin embargo, este acercamiento conceptual y empírico no es uniforme sino que ha evolucionado desde concepciones normativas hacia otras de carácter multidimensional. El presente trabajo analiza las versiones clásica y reformulada de esta teoría, a través de los presupuestos, las evidencias empíricas, las inconsistencias y las investigaciones desarrolladas por ambas líneas de trabajo. Finalmente, evalúa las implicaciones que ha llevado consigo dar por ciertos algunos de sus principios, insuficientemente contrastados, en la práctica educativa.
Bienestar, variables personales y afrontamiento en jóvenes universitarios
Authors: Fierro-Hernández Carlos , Jiménez Rodríguez José Antonio
Published: September 2021

El marco de la investigación lo constituye el hecho, repetidamente encontrado, de que la conducta de afrontamiento se relaciona no sólo con los acontecimientos adversos por afrontar, sino también con características personales. Se informa aquí, pues, de dos Estudios realizados con jóvenes universitarios. En ellos se han investigado las relaciones entre distintas variables de personalidad y modos de afrontamiento de hechos adversos por parte de esos sujetos. El análisis correlacional ha puesto de manifiesto que con los modos de afrontamiento aparecen asociadas todas las variables personales examinadas: adaptación social, neuroticismo, extraversión, lugar interno de control, bienestar personal. Sin embargo, al pasar a un análisis de correlaciones parciales, resulta que solamente extraversión y, sobre todo, bienestar personal correlacionan con los modos de afrontamiento.
Comparación social y autoevaluación desde un enfoque evolucionista
Authors: Gómez-Jacinto Luis
Published: September 2021

Este trabajo analiza el impulso de evaluación de las propias opiniones y capacidades desde una perspectiva evolucionista. El proceso social que permite la autoevaluación es la comparación social. Se propone que el origen del proceso de comparación social y autoevaluación se deriva de la competición social a través de dos autoconceptos: los potenciales de posesión de recursos y de posesión de atención social. El equivalente psicológico de estos dos conceptos es el de la autoestima. La autoestima evolucionó como un soció metro que permite al Homo Sapiens calibrar su grado de pertenencia social/exclusión social en los grupos de referencia. Las personas se motivan para comportarse de tal modo que conserven su autoestima, puesto que las conductas de mantenimiento de la autoestima suelen reducir la posibilidad de ser ignorado, evitado o excluido por los demás. Esta autoevaluación es más sensible a la exclusión de las personas íntimas que al rechazo de personas alejadas del círculo más cercano. Esta sensibilidad está relacionada con el nivel de intimidad que se mantiene con los otros miembros del grupo, con los dominios de desempeño y con la relevancia para el yo. Este modelo de mantenimiento de la autoevaluación es un mecanismo que resuelve un problema evolutivo al que hubo de enfrentarse el Homo Sapiens en algún momento clave de su evolución.

Published: September 2021

Resistance to chemotherapy is the main obstacle in contemporary ovarian cancer treatment. The aim of this study was the evaluation of expression of HERC5, IFIH1, SAMD4, MCTP1 and SEMA3A mRNA and assessment their role in resistance to cisplatin, paclitaxel, doxorubicin and topotecan in seven ovarian cancer cell lines. MTT assay was used in resistance assessment. Quantitative polymerase chain reaction was performed to measure the expression levels of the genes. We observed different levels of resistance among cell lines. The resistance was not related to the expression of drug transporters genes. The expression of HERC5 and IFIH1 genes was upregulated, and the expression of SEMA3A gene was downregulated. Expression of SAMD4 was upregulated in PEA1, PEA2, and PEO23 cell lines, and expression of MCTP1 was downregulated in A2780, PEA2, and PEO23 cell lines. Upregulation of HERC5, IFIH1, and SAMD4 and downregulation of SEMA3A and MCTP1 in TOP-resistant ovarian cancer cell lines may suggest some role of those genes in topotecan resistance development.
Demographic Profiles for Cross-Cultural Adjustment of Expatriates in Nigeria
Authors: Akhimien Goodheart Okharedia , Umemezia Evelyn
Published: September 2021

This paper offers insight into the demographic profiles of expatriates for successful cross-cultural adjustments in the context of Nigeria. It considers the following demographics: age, gender, marital status, international work experience, and time spent in the host country. The study adopted cross-sectional survey research by utilizing a questionnaire to collect data from one hundred and fifty-two (152) expatriate residents in Nigeria, who relocated from 22 different countries and who have worked and lived in Nigeria for over six months. The paper discovered that marital status, international work experience, and length of stay in Nigeria rather than age and gender are the demographic profiles influencing and required for the successful cross-cultural adjustment of expatriates in the Nigerian context. It concludes that the more organizations recruit, select, and deploy expatriates whose demographic profiles reflect the higher length of stay/time in Nigeria, higher level of international work experience, and single/unmarried, the higher the successful cross-cultural adjustment of such expatriates in the Nigerian context.
Price Markups and Upstreamness in World Input-Output Data
Authors: Colonescu Constantin
Published: September 2021

This research uses the publicly available World Input-Output Database (WIOD) to investigate the relationship between an industry’s markup and its upstreamness, the industry’s position in the vertical chain of production; the research also identifies common attributes among high-markup industrial sectors: higher-markup industries display a higher level of capital compensation and a lower share of labour and other inputs in the value of output. Finally, it is found that upstream industries, those producing mostly raw materials and intermediate products enjoy higher market power than their downstream counterparts. This result could be among the first in the literature to find evidence of double marginalization at an industry level of aggregation. It also suggests that virtually all final product prices may incorporate substantial markups through their inputs.
Food Self-Provisioning in the Czech Republic – A Comparison of Suburban and Peripheral Regions of Rural South Moravia
Authors: Svobodová Ilona , Drlík Jan , Spěšná Daniela , Delín Miloslav
Published: September 2021

The Czech Republic ranks among the countries with a strong tradition of home food self-provisioning. In this article, we focused our attention specifically to the traditional and frequently neglected phenomenon of rural self-provisioning while newly introducing a data-based analysis of the phenomenon in two areas, i.e., suburbs and peripheries of the South Moravian region. Unlike the research carried out in the CR or EU to date, our survey aims exclusively at the analysis of households with access to land, which allow a more detailed scrutiny of growing a wide range of commodities, the attitudes to it and its perspectives. The results of the field study carried out in 178 rural households in two types of South Moravian regions (suburban and peripheral) from 2017 show the regional differences in food self-provisioning. They also contribute to a better understanding of a phenomenon whose variability within a rural territory is quite known a little. Even though the suburban and peripheral regions have very comparable natural conditions and opportunities of growing crops (a similar type of estate, nearly the same size of the gardens surveyed), we can observe rather remarkable differences, especially in the extent of the areas being farmed and in the scale of breeding domesticated animals (work demanding activities). Compared to that, only negligible differences were found in growing commodities demanding less work (fruit and tomato growing). The identified differences in attitudes to self-provisioning in the observed regions (depending on the varied types of population in the regions) allow for analysing the perspectives of particular self-provisioning activities both in South Moravia and the CR on the whole.
Siting military base camps through an MCDA framework
Authors: Cegan Jeffrey C. , Golan Maureen S.
Published: September 2021

The process used to determine site suitability for military base camps lacks a formal framework for reducing relative risks to soldier safety and maximise mission effectiveness. Presently, military personnel responsible for determining site suitability of a base camp must assess large amounts of geographic, socioeconomic and logistical data, without a decision analysis framework to aid in the process. By adopting a multicriteria decision analysis (MCDA) framework to determine site suitability of base camps, battlespace commanders can make better, more defensible decisions. This paper surveys US Army officers with recent base camp experience to develop a set of initial criteria and weights relevant to base camp site selection. The developed decision framework is demonstrated using an MCDA methodology in an illustrative example to compare alternative base camp locations within a designated Area of Interest (AoI). Leveraging the site ranking output and/or criteria weights resulting from the methodology provides decision-making support that can be used in the field when time, resources and data may not be readily available.

Authors: Ruiz Mónica Vallejo , González Mª Begoña Alfageme , Cano José Miguel Niezto , Soto Ana Torres , Pruaño Antonio Portela , Hernández Mª Luisa García
Published: September 2021

Objective: This contribution aims to introduce a conceptual framework on generational diversity of teachers in order to analyze and understand its influence on the processes and results of professional interaction in schools.

Methodology: In this conceptual piece, first, the relevance of generational diversity among teachers in their workplace is examined and justified, emphasizing the increasing aging of teaching staff. Next, generational diversity is explored by analyzing the concept of generation and the attributes used to distinguishing generations (particularly, age). Furthermore, evidence is considered regarding the impact on the construction of teacher relationships, paying particular attention to the context of collaborative relationships between teachers belonging to different generations and its effects on teacher learning and identity.

Findings: Conclusions are drawn as to the potentialities of intergenerational learning.

Value added: Despite representing a clear challenge for the educational organizations, generational diversity and intergenerational collaboration among teachers and school leaders have been scarcely studied so far.

Recommendations: Conclusions are drawn as to the potentialities of intergenerational learning and implications for professional induction and collegial professional development are presented as well.

Authors: Manna Sumanta , Kombathula Sri Harsha , Gayen Sanjib , Varshney Sonal , Pareek Puneet
Published: September 2021

Background: This study was conducted to assess the dosimetric impact of FFF beam plans on high-grade brain neoplasms using the VMAT technique when compared with FF beam plans.

Material and Methods: Thirty patients with high-grade brain neoplasms, who had received radiotherapy using VMAT technique retrospectively were selected for this study. All the patients were planned for VMAT using 6MV_FF beam and the same plan was re-optimized using 6MV_FFF beam keeping the same dose constraint. Radiotherapy dose distribution on planning target volume (PTV) and organs at risk (OAR), target conformity index (CI), Homogeneity Index (HI), Low dose volume in the patient (V5, V10, V20, and V30), and Integral dose to the whole body in both plans were compared.

Results: The PTV coverage and OAR’s showed no significant differences in dose distribution between the FFF and FF beam VMAT planning. There was a reduction of the average maximum dose in the right eye, left eye, right optic nerve, and left optic nerve using FFF beams. The reduction in average low dose volume was observed in V5, V10, V20, V30, and Mean Dose. Also, a significant reduction was observed in the integral dose to the whole body using the FFF beam.

Conclusions: Using FFF beams with VMAT is doable for the treatment of high-grade brain neoplasms, and the delivery mode of the FFF beam in VMAT may yield similar results to FF beam which should be confirmed in a large scale prospective clinical trial.
Trend and prediction of COVID-19 outbreak in Iran: SEIR and ANFIS model
Authors: Shafiekhani Sajad , Khalilabad Touraj Harati , Rafiei Sima , Sadeghi Vahid , Jafari Amir Homayoun , Gheibi Nematollah
Published: September 2021

Background: Mathematical and predictive modeling approaches can be used in COVID-19 crisis to forecast the trend of new cases for healthcare management purposes. Given the COVID-19 disease pandemic, the prediction of the epidemic trend of this disease is so important.

Methods: We constructed an SEIR (Susceptible-Exposed-Infected-Recovered) model on the COVID-19 outbreak in Iran. We estimated model parameters by the data on notified cases in Iran in the time window 1/22/2020 – 20/7/2021. Global sensitivity analysis is performed to determine the correlation between epidemiological variables and SEIR model parameters and to assess SEIR model robustness against perturbation to parameters. We Combined Adaptive Neuro-Fuzzy Inference System (ANFIS) as a rigorous time series prediction approach with the SEIR model to predict the trend of COVID-19 new cases under two different scenarios including social distance and non-social distance.

Results: The SEIR and ANFIS model predicted new cases of COVID-19 for the period February 7, 2021, till August 7, 2021. Model predictions in the non-social distancing scenario indicate that the corona epidemic in Iran may recur as an immortal oscillation and Iran may undergo a recurrence of the third peak.

Conclusion: Combining parametrized SEIR model and ANFIS is effective in predicting the trend of COVID-19 new cases in Iran.
The Opinions on Force Protection in Asymmetric Operations
Authors: Cotoarbă Ionel , Mituleţu Ion
Published: September 2021

The future conflicts will take place in increasingly complex operational environments and will largely include conventional, asymmetric or hybrid opponents. The battle space that has acquired new valences and the asymmetrical nature of the current operational environment require the perpetual reconfiguration of the rules of engagement. Within the asymmetric actions, the enemy will focus their efforts on attacking vulnerable military structures, which have a degree of protection inadequate for the operational situation. Therefore, the protection of force is a key element in the effective management of situations, maintaining the pace of actions and the ability to fight in the development of asymmetric operations. From the range of asymmetric actions that manifests itself globally, we aim to conduct an analysis focused on force protection measures specific to counterinsurgency, counter-guerrilla and counter-terrorism operations. The place and role of force protection in asymmetric operations attest to the fact that specific measures are aimed in particular at maintaining the morale and combat capability of their own forces throughout the range of missions performed, as well as protecting the civilian population in the area of action.
In Vitro Assessment of N-Phenyl Imides in the Management of Meloidogyne Incognita
Authors: Fabiyi O.A. , Claudius-Cole A.O. , Olatunji G.A.
Published: September 2021

The infestation with root knot nematode Meloidogyne spp. is a key issue in agriculture. Conventional control methods are based on the use of synthetic nematicides, which comes with severe environmental problems. In this study, n-phenyl imide and n-phenyl phthalamic acid were synthesized and reacted independently with Enantia chlorantha crude extract–manganese chloride complex. The effects of the resulting organic compounds were appraised against the root knot nematode Meloidogyne incognita (Kofoid and White 1919) juveniles and eggs in two laboratory experiments. The most active compound was n-phenyl phthalamic acid (PN/TLMA) with 4% egg hatch over a 9-day observation after treatment as against distilled water which recorded 100% egg hatch at 9 days after treatment. n-Phenyl phthalamic acid showed 100% juvenile mortality at 10 days of observation compared to carbofuran dissolved in water (CBFN/water) and carbofuran dissolved in hydroxypropyl-β-cyclodextrin (CBFN/HPCD) while no outstanding (P < 0.05) difference was recorded between the effects of other organic compounds and carbofuran in both solvents. The different rates of treatment applications were not appreciably (P<0.05) dissimilar on percentage juvenile mortality and egg hatch. The nematicidal test results indicated that the synthesized imide compounds with manganese complex moiety are a promising basis for developing new nematicidal compounds with less environmental hazard.

Making errors is a natural process of learning. Writing as a productive skill is important for students to express their ideas. However, students conducted errors in the productive skills. Therefore, this study is intended to find out types of errors made by students in written English. This study employed the qualitative method where the Error Analysis was implemented. The subject of this study is students in first grade of SMAN 1 Abdya and the object of this study were the errors found in written English. The population of this research was all of students in first grade which consists of 208 students from all study programs where 25 % of the populations were taken as the sample. To collect the data, written tests were conducted. The written test shows the percentage of writing errors, including omission errors, which is 58.38%, misformation errors with a total of 16.48%, misordering error 13.89%, and addition of 11.26%. The errors were found when students omitted 'to be' as main verb. Second, students tend to add 'to' after modal auxiliaries such as 'can' or 'will'. Third, misformation errors happened when students could not form the verb correctly. Last, the misordering errors were produced when students put words randomly. Consequently, it was discovered that the errors made by students were impacted by their native language, and this is the interlanguage move.

Higher education is today characterised by increasing student groups and high pressure on teaching staff. In these circumstances, it may be difficult to provide appropriate scaffolding of activities that many students find challenging, for example, academic and discipline-specific writing. It may also be difficult to align such support with principles associated with effective learning. In this paper, we present the design of the bachelor thesis writing support for students at a university of technology. The support is delivered by a communication division and reaches approximately 900 students each year. The paper describes the principles guiding the design and use results from a student survey to illuminate the challenges and affordances of the approach. The survey results show that students appreciate the module and its focus on dialogic feedback, student engagement and student activity. Our results also show that one of the challenges for some students is to negotiate advice from multiple sources, primarily content supervisors and writing staff. Despite such challenges, the design is an example of a sustainable, large-scale writing module based on research on feedback and learning.
Reflective Writing on an ESL Writing Course

Research shows that student reflective writing is a valuable window into student learning, particularly student metacognition; however, our knowledge of the challenges of accessing metacognition to inform curriculum design and assessment practices in the ESL (English as a Second Language) context is less robust. This paper reports two qualitative studies of student reflective writing on an ESL writing course within a teacher education programme. The studies investigate how student metacognition manifests itself in reflective papers and how mapping student metacognition can inform evidence-based curriculum design and assessment. The data comes from several iterations of an ESL writing course and is analysed using directed and conventional content analyses. Our results expose a complex relation between metacognition, curriculum design and assessment practices: 1) unless scaffolded by the curriculum design to use precise terminology, students resort to expressing their understanding of the course content in terms of everyday, vernacular language and 2) student reflective writing not only provides a more nuanced picture of their learning than the final course grades but is invaluable for developing scaffolding and assessment practices. Based on our results, we recommend integrating structured reflection as part of the regular curricula to gauge ESL student metacognition and monitor more precisely their uptake of course content.

Yrkesgruppers anspråk på arbetet med barn i behov av särskilt stöd

This study aims to illuminate preschool teachers describe which occupational groups – preschool teachers and special educational needs coordinators (SENCOs) – claim jurisdiction (i.e. the area that the professional group controls) over the work with children in need of special support. The data consist of interviews with 15 preschool teachers. The analysis is based on Abbott's (1988) division of professional work into three aspects: a) formulation of a problem b) reasoning about the problem and c) treating the problem. One area where preschool teachers claim jurisdictional control is related to the formulation of the problem. When it comes to the aspect of the professional work which concerns reasoning about the problem, the preschool teachers report that SENCOs claim jurisdictional control instead. The results show a less straightforward image of the treatment of the problem. Preschool teachers sometimes report themselves to claim jurisdictional control over treatment and other times report that SENCOs have jurisdiction over the treatment of the problem. In the discussion, jurisdiction is related to the various aspects of professional work with children in need of special support and the issue of inclusion. The fact that SENCOs seem to have a strong jurisdiction over treatment and expert knowledge of children’s perceived shortcomings could contribute to the preschool teachers renouncing responsibility for children in need of special support. Another conclusion is that preschool teachers need to be strengthened in their professional roles and that increased special educational knowledge could contribute to preschool teachers feeling more secure in their professional roles and thus are able to meet all children’s needs in preschool.

Четвертая часть обзора посвящена влиянию различных типов промышленного загрязнения на жизненное состояние древостоев и вопросам определения адаптивных стратегий древесных видов к техногенезу. Рассмотрены современные методические подходы к оценке жизненного состояния древостоев, выделены наиболее перспективные из них. Показано однозначное ухудшение жизненного состояния древостоев вне зависимости от древесного вида и типа загрязнения, однако степень ухудшения во многом зависит от древесного вида и типа загрязнения. Рассмотрены вопросы устойчивости биосистем к техногенезу, в основе которой лежат адаптивные реакции, протекающие на всех уровнях организации живого – от цитогенетического до экосистемного. Отдельно рассмотрены адаптивные реакции, характеризующие металлоустойчивость растений. Показано развитие теории адаптивных стратегий растений начиная от эколого-ценотических стратегий Раменского-Грайма. Промышленное загрязнение, как новый для растений в историческом плане фактор, вызывает необходимость разработки вопросов, связанных с адаптивными стратегиями видов к техногенезу, в основе которых лежат адаптивный потенциал, изменчивость, устойчивость и экологическая пластичность видов. Предложен авторский подход к определению и выявлению адаптивных стратегий к техногенному фактору, основанный на анализе современных работ в этой области и материалов собственных многолетних исследований.
