The Effects of Scenario-Based STEM Project Design Process with Pre-service Science Teachers: 21st Century Skills and Competencies, Integrative STEM Teaching Intentions and STEM Attitudes
Authors: Deniş Çeliker Huriye
Published: December 2020

The purpose of this study is to determine the effects of the scenario-based STEM project design process on pre-service science teachers’ perceptions of 21st-century skills, competencies, integrative STEM teaching intentions, and STEM attitude. In the study, a pretest-posttest quasi-experimental design, which does not contain a control group, was used. The participants of the research are 66 fourth-grade pre-service science teachers in the south-west of Turkey. The 21st-century skills and competencies scale and an integrative STEM teaching intentions questionnaire, and a STEM attitudes scale were used as a pre-test and post-test. Pre-service teachers designed projects using engineering design processes to solve the problems in the scenarios given to them. In the analysis of the data, paired-samples t-test and Wilcoxon Signed Rank Test were applied using SPSS-21. The results show that designing a scenario-based STEM project certainly contributed to the 21st-century skills competence perceptions, STEM teaching intentions, and STEM attitudes of pre-service science teachers.
Dialect variation in Scottish Gaelic nominal morphology: A quantitative study
Authors: Iosad Pavel , Lamb William
Published: December 2020

This paper presents a dialectometric analysis of Scottish Gaelic morphology, with a focus on the noun phrase, using previously unpublished data from the Linguistic Survey of Scotland. Fifty-five morphological features were extracted across 201 survey points, and the data subjected to a variety of analyses, including cluster analysis, regression, and correlation analysis. We establish that the Gaelic noun system shows robust diatopic (i.e. geographical) variation; this challenges previous assertions in the literature, which describe Gaelic morphosyntax as geographically uniform. In addition, we argue that our dialectometric results provide an insight into the grammatical structure of the language that is not easily achievable through the analysis of individual varieties. In particular, we argue that the results highlight a dissociation between morphological categories such as case and gender and their morphophonological exponents, which are particularly complex in Scottish Gaelic. The paper thus serves as a proof of concept for the use of dialectometric findings in a theoretical context.
Vocatives as parenthetical adjuncts: Evidence from Arabic
Authors: Haddad Youssef A.
Published: December 2020

Vocatives are noun phrases that are generally used as calls to attract an addressee’s attention or as addresses to maintain contact with her/him. In her 2014 book, Virginia Hill analyzes vocatives as forms of address; they are converted to syntax as nominal functional projections in the form of vocative phrases. Drawing on work by Speas and Tenny (2003) and Moro (2003), she further posits that vocatives merge as arguments of a speech act phrase in the left periphery. This merging site, Hill 2014 and others (e.g., Slocum 2016) argue, is fixed. This is so despite the fact that vocatives may appear in different positions in their host clause. Under this account, pre-vocative elements appear in that location as a result of movement. This paper presents counterevidence to this argument from Arabic. Using naturally occurring data, mainly from Twitter, the paper shows that Arabic vocatives do not merge in a fixed position in the left periphery. Rather, they are parenthetical adjuncts whose relationship with their host clause is minimally constrained. If correct, the analysis serves as an invitation for a closer and more data-driven look at vocatives in other languages, including those in which vocatives have already been explored.
Introduction to and aims in the design of earthquake resisting shear wall structures
Authors: Taylor R. G.
Published: December 2020

Some three years ago the New Zealand National Society for Earthquake Engineering initiated a series of group discussions with the aim of examining seismic design philosophies and methodology, relevant to different types of engineering structures. The results of the first of these discussions, on the seismic design of ductile moment resisting reinforced concrete frames, were subsequently published in a series of papers in the Bulletin of the Society.  The publication was followed by workshop meetings, held in the main centres of New Zealand and attended mainly by practising structural engineers. During these meetings the recommendations of the group were disseminated and applied to prototype structures.

Published: December 2020

Objective To demonstrate the effects of chin-down maneuver on swallowing by using high-resolution manometry (HRM).Methods HRM data of 20 healthy subjects and 64 dysphagic patients were analyzed. Participants swallowed 5 mL of thin and honey-like liquids in neutral and chin-down positions. HRM was used to evaluate maximal velopharyngeal pressure/area, maximal tongue base pressure/area, maximal pharyngeal constrictor pressure, pre-/post-swallow upper esophageal sphincter (UES) peak pressure, minimal UES pressure, UES activity time, and nadir duration.Results Compared to the neutral position, the chin-down maneuver significantly increased tongue base pressure in both normal and dysphagic groups as well as for both honey-like and thin viscosities, although the honey-like liquid did not reach statistical significance in the dysphagic group. Regarding pharyngeal constrictors and pre-swallow peak UES pressure, the healthy group showed a significant decrease in thin liquid swallowing and decreasing tendency in honeylike liquid swallowing. UES nadir duration was significantly decreased for honey-like liquid swallowing in the dysphagic group and for both thin and honey-like liquids in the healthy group. UES nadir duration of honey-like and thin flow swallowing in the dysphagia group was 0.26 seconds after the chin-down maneuver, which was severely limited.Conclusion This study showed a different kinetic effect of the chin-down maneuver between the healthy and dysphagic groups, as well as between thin and honey-like viscosities. The chin-down maneuver increased tongue base pressure and decreased UES nadir duration, which the latter was severely limited in dysphagic patients. Therefore, appropriate application of the chin-down maneuver in clinical practice is required.

Published: December 2020

Objective To determine the most optimal needle insertion point of extensor indicis (EI) using ultrasound.Methods A total 80 forearms of 40 healthy volunteers were recruited. We identified midpoint (MP) of EI using ultrasound and set MP as optimal needle insertion point. The location of MP was suggested using distances from landmarks. Distance from MP to medial border of ulna (MP-X) and to lower margin of ulnar head (MP-Y) were measured. Ratios of MP-X to Forearm circumference (X ratio) and MP-Y to forearm length (Y ratio) were calculated. In cross-sectional view, depth of MP (Dmp), defined as middle value of superficial depth (Ds) and deep depth (Dd) was measured and suggested as proper depth of needle insertion.Results Mean MP-X was 1.37±0.14 cm and mean MP-Y was 5.50±0.46 cm. Mean X ratio was 8.10±0.53 and mean Y ratio was 22.15±0.47. Mean Dmp was 7.63±0.96 mm.Conclusion We suggested that novel optimal needle insertion point of the EI. It is about 7.6 mm in depth at about 22% of the forearm length proximal from the lower margin of the ulnar head and about 8.1% of the forearm circumference radial from medial border of ulna.

Published: December 2020

Objective To investigate the reliability of knee extensor strength measurements using a supine hand-held dynamometer (HHD) anchoring frame in patients with limited physical activity. Although an HHD is suitable for bedside use, its inter-rater reliability is low because measurements can be influenced by tester strength.Methods Maximal knee extensor isometric strength was measured using an HHD anchored to the supine frame. Three trials of three maximal contractions were assessed by two raters.Results A total of 33 inpatients who were non-ambulatory due to acute illness participated in the study. The intraclass correlation coefficients were 0.974 (inter-rater) and 0.959 (intra-rater). The minimal detectable changes in intra- and inter-observer measurements were 29.46 N (24.10%) and 36.73 N (29.26%), respectively. The limits of agreement ranged from -19.79% to 24.81% for intra-rater agreement and from -21.45% to 37.07% for inter-rater agreement.Conclusion The portable dynamometer anchoring system can measure the isometric strength of the knee extensor reliably in the supine position, and could be used for measurements in patients who have difficulty visiting the laboratory and maintaining a seated posture.

Published: December 2020

Objective To present new classification methods of knee osteoarthritis (KOA) using machine learning and compare its performance with conventional statistical methods as classification techniques using machine learning have recently been developed.Methods A total of 84 KOA patients and 97 normal participants were recruited. KOA patients were clustered into three groups according to the Kellgren-Lawrence (K-L) grading system. All subjects completed gait trials under the same experimental conditions. Machine learning-based classification using the support vector machine (SVM) classifier was performed to classify KOA patients and the severity of KOA. Logistic regression analysis was also performed to compare the results in classifying KOA patients with machine learning method.Results In the classification between KOA patients and normal subjects, the accuracy of classification was higher in machine learning method than in logistic regression analysis. In the classification of KOA severity, accuracy was enhanced through the feature selection process in the machine learning method. The most significant gait feature for classification was flexion and extension of the knee in the swing phase in the machine learning method.Conclusion The machine learning method is thought to be a new approach to complement conventional logistic regression analysis in the classification of KOA patients. It can be clinically used for diagnosis and gait correction of KOA patients.

Published: December 2020

Objective To identify the prevalence and characteristics of neuropathic pain (NP) in patients with spinal cord injury (SCI) and to investigate associations between NP and demographic or disease-related variables.Methods We retrospectively reviewed medical records of patients with SCI whose pain was classified according to the International Spinal Cord Injury Pain classifications at a single hospital. Multiple statistical analyses were employed. Patients aged <19 years, and patients with other neurological disorders and congenital conditions were excluded.Results Of 366 patients, 253 patients (69.1%) with SCI had NP. Patients who were married or had traumatic injury or depressive mood had a higher prevalence rate. When other variables were controlled, marital status and depressive mood were found to be predictors of NP. There was no association between the prevalence of NP and other demographic or clinical variables. The mean Numeric Rating Scale (NRS) of NP was 4.52, and patients mainly described pain as tingling, squeezing, and painful cold. Females and those with below-level NP reported more intense pain. An NRS cut-off value of 4.5 was determined as the most appropriate value to discriminate between patients taking pain medication and those who did not.Conclusion In total, 69.1% of patients with SCI complained of NP, indicating that NP was a major complication. Treatment planning for patients with SCI and NP should consider that marital status, mood, sex, and pain subtype may affect NP, which should be actively managed in patients with an NRS ≥4.5.

Objective To evaluate the safety and effectiveness of the community-based cardiac rehabilitation (CBCR) program that we had developed.Methods Individuals aged >40 years with cardiovascular disease or its risk factors who were residing in a rural area were recruited as study subjects. The CBCR program, which consisted of 10 education sessions and 20 weeks of customized exercises (twice a week), was conducted in a public health center for 22 weeks. Comprehensive outcomes including body weight, blood glucose level, and 6-minute walk distance (6MWD) were measured at baseline, 11th week, and completion. Furthermore, the outcomes of young-old (65–74 years) and old-old (≥75 years) female subjects were compared.Results Of 31 subjects, 21 completed the program (completion rate, 67.7%). No adverse events were observed, and none of the subjects discontinued the exercise program because of chest pain, dyspnea, and increased blood pressure. Body weight and blood glucose level were significantly decreased, and 6MWD was significantly increased following program implementation (p<0.05). Both young-old and old-old women exhibited an improvement in blood glucose level and 6MWD test (p<0.05).Conclusion We reported the results of the first attempted CBCR in South Korea that was implemented without adverse events during the entire program. Improved aerobic exercise ability and reduced risk factors in all participants were observed. These improvements were also achieved by older adults aged ≥75 years.

Examining Holland’s model for Ecuadorian youth. Tool development and psychometric implications for vocational counseling
Authors: Wołońciej Mariusz Tomasz
Published: December 2020

Holland’s (1997) scale is one of the most frequently used measures of vocational personality. The study describes the multiphase development and cultural validation of a short version of the sixfactor scale on a representative sample of 1735 Ecuadorian undergraduates. The Questionnaire of Vocational Preferences of Youth (Inventario de las Preferencias Profesionales de Jovenes: IPPJ) as the first culturally-rooted tool for Ecuadorian youth corresponds with the circular model
by Holland (1997). Factorial analysis (EFA and CFA), validity, follow-up study, and reliability indicators support the factorial
equivalence of the new, short version of the IPPJ. Some practical implications are outlined for vocational guidance in Ecuador.

Authors: Rożnowski Bohdan , Kot Paweł
Published: December 2020

The article deals with the problem of the impact of resources being goals formed in the perspective of transition, self-assessment and self-efficacy in social roles on effectiveness of the school-to-work transition among the youth. The study took the form of a questionnaire used to survey 210 people (117 females and 93 males). The average age of respondents was M = 24.87; SD = 1.11. The study used the Multidimensional Questionnaire of Plans, the Scale of Self-Efficacy in Life Roles and Rosenberg’s Self-Esteem Scale. The resource explaining having employment after graduating from school by the youth was having work during studies (preferably based on a contract or civil law contracts), avoiding failures in setting goals and selfefficacy in the role of a student. In the case of having a job consistent with education after graduating from school, the resource explaining this relationship was the level of self-esteem and self-efficacy in the role of a student.
Hope-Action Theory and Practice
Authors: Amundson Norman , Niles Spencer , Joon Yoon Hyung
Published: December 2020

Hope-Action Theory presents a theoretical structure that holds Hope as the center point of career development. Associated with hope are competencies such as self-reflection, self-clarity, visioning, goal setting and planning, implementation, and adapting. There also are environmental factors that influence the entire career development process. In order to assess the practical utility of Hope-Action Theory a series of intervention research studies were initiated in different contexts. This article reviews the results from these studies. The first one applied specific active interventions with a group of internationally trained health professionals. The second study involved unemployed clients using a series of face-to-face and online interventions. The third group focused on the needs of refugees and was set up with a control and experimental groups using a two week group delivery approach. Positive results from all of these studies supports the utility of Hope-Action Theory and the set of active interventions that were used in this research.

Zur Beschränkung rechtlicher Verpflichtungen auf das äußere Verhalten bei Gottfried Achenwall
Authors: von der Pfordten Dietmar
Published: December 2020

Kant famously distinguished between an internal and an external relationship between humans and he limited law to the external relationship. However, this distinc­tion and limitation was not invented by Kant but the outcome of a long development of late 18th century natural law. One central figure was Gottfried Achenwall, on whose standard book Kant lectured at the University of Koenigsberg. In this text, I show the details of Achenwall’s limitation of natural law to an external relationship, following the different editions from 1750 (1.) up to 1781 (7.). Achenwall enlarged the scope of natural law in the course of these editions and was therefore forced to mention the good resp. God as a last source.
Zwischen Verfolgung und Eingliederung
Authors: Weineck Benjamin
Published: December 2020

The history of the Kızılbaş-Alevis in the Ottoman Empire is often remembered and written as a history of persecution and oppression. This study opens up a perspective on the Ottoman state and the Kızılbaş-Alevis beyond such dominant narratives. It approaches the period between the 16th and the 18th century and investigates how the formerly persecuted Kızılbaş interacted with local and imperial Ottoman state agents. After the persecution of the Kızılbaş by the state both sides entered a relationship which aimed at conveniently accommodating the heterogeneous Kızılbaş-Alevi communities to the (local) Ottoman apparatus of power. Relying on a wide range of Ottoman sources, the author reveals formerly unstudied contexts in which the Kızılbaş-Alevis arranged themselves with and within the Ottoman state. As such, this work challenges widespread notions of persecution or essentialist ideas of Heresy and critically rethinks the social history of the Kızılbaş-Alevis in the Ottoman Empire.
Tripolitanien und Bengasi um 1900
Authors: Sievert Henning
Published: December 2020

This study examines the production of knowledge on Tripolitania, Benghazi and Fezzan by the late Ottoman state, the ways in which local subjects and imperial officials communicated and what kind of agency they had. They operated in a continuum between a discourse of civilisation and complete political integration, between ambitious aspirations and prosaic practice. Ongoing processes of state building at the same time increasingly necessitated the employment of intermediaries that the Italian colonial regime after 1911 would lack. By looking at knowledge, communication and micropolitics in these remote parts of the realm, the study contributes to the history of both Libya and the Ottoman Empire as a whole.

Authors: UNAL Edip
Published: December 2020

Amaç: Turner sendromu X kromozomlarından birinin kaybı veya yapısal bozukluğu sonucu gelişen ve 2500 doğumda bir görülen genetik bir hastalıktır. Turner sendromu birçok sistemi etkilemektedir. Bu çalışmada Turner sendromlu olgularımızın klinik özellikleri ve eşlik eden anormalliklerin sıklığının değerlendirilmesi amaçlanmıştır.

Yöntemler: Çocuk Endokrinolojisi polikliniğinde Ocak 2013-Ocak 2020 tarihleri arasında Turner sendromu tanısı alan hastaların dosyaları retrospektif olarak incelendi. Dosya kayıtlarından hastaların antropometrik ölçümleri, karyotip analizi, başvuru yaş ve şikayetleri, eşlik eden kardiyak, renal ve işitme problemleri ve otoimmün hastalık olup olmadığı kaydedildi.

Bulgular: Çalışmaya ortalama başvuru yaşı 9,83±3,81 olan 28 hasta alındı. Yirmi sekiz hastanın 13’ünde ( % 46,4) karyotip analizi 45, X0 saptandı. Başvuru esnasında hastaların ortalama boy standart deviasyon skoru: -3,61 ± 1,17 idi. Yirmi sekiz olgunun 7’sinde (% 25) kardiyak patoloji, 3’ünde (% 10,7) atnalı böbrek anomalisi, 3’ünde (% 10,7) Hashimoto tiroiditi hastalığı ve 2’sinde (% 7,1) Alanin transaminaz yüksekliği saptandı. İşitmesi değerlendirilen 19 hastanın 8’inde (% 42,1) iletim tipi işitme kaybı mevcuttu. Tanı esnasında 27 hastanın pubertesi Tanner evre 1 iken, 1 olguda pubertenin spontan başladığı ve menarş olduğu tespit edildi. Tüm hastalar boy kısalığı ile başvurmuştu.

Sonuç: Turner sendromunun en sık görülen iki bulgusu boy kısalığı ve gecikmiş pubertedir. Bunun dışında kalp ve böbrek hastalıkları, gastrointestinal sistem ve işitme problemleri, otoimmün hastalık sıklığında artış gibi başka sistemleri de etkilemektedir. Daha iyi bir final boya ulaşmak ve eşlik eden patolojilerle ilgili komplikasyonları önlemek için erken tanı oldukça önemlidir. Bu çalışma, çocuklarda boy kısalığı ve hipergonadotropik hipogonadizm gibi kardinal bulguların olmamasının, Turner sendromu tanısını ekarte etmeyeceğini göstermiştir.

Authors: Kalantari Heibatullah , Khodayar Mohammad Javad , Shirani Kobra , Shirani Maryam
Published: December 2020

: Mycotoxin contamination of rice has been introduced as a big challenge for public health in developing countries in numerous studies. Rice consumption is also considered the main source of secondary metabolites in Iran. Given the diversity of climatic conditions in this region as well as unsuitable storage conditions, including high temperature and humidity, rice can be extremely contaminated via various fungi. The current study is a review of the occurrence of mycotoxins in rice in Iran. In this regard, some investigations had revealed that rice could be contaminated by mycotoxins such as aflatoxins (AFTs) (B1, B2, G1, and G2), deoxynivalenol (DON), fumonisin (FM) (B1 and B2), ochratoxin A (OTA), T-2 toxin, and zearalenone (ZEN). Moreover, the amount of mycotoxins in rice was reported in varying ranges in different provinces and regions and normally less than Iranian maximum tolerated dose (MTD). Given the importance of rice in the Iranian diet, it was finally recommended to screen consumed rice to find about fungal contaminations and mycotoxins.

Background: Nosocomial infections are important medical concerns in developed and developing countries. Pseudomonas aeruginosa is considered the third leading cause of nosocomial infections following Staphylococcus aureus and Escherichia coli. Objectives: The present study aimed to determine the antibiotic resistance of isolated P. aeruginosa strains in the patients admitted to Imam Reza Hospital in Kermanshah, Iran. Methods: This descriptive, cross-sectional study was conducted on 900 patients with positive P. aeruginosa cultures who were admitted to Imam Reza Hospital in Kermanshah, Iran during 2016-2018. Bacterial isolates were separated using laboratory tests, and the standard disc-diffusion method was used to assess antibiotic susceptibility based on the CLSI protocol. Data analysis was performed in SPSS version 24. Results: The majority of the P. aeruginosa-positive cases were isolated from the emergency ward (44.3%), intensive care unit (21.9%), blood samples (40.4%), and urine samples (18.7%). The highest antibiotic resistance was observed against cotrimoxazole, ceftriaxone, ampicillin, ampicillin-sulbactam, nitrofurantoin, nalidixic acid, cefazolin, and cefixime. In addition, ciprofloxacin and imipenem were the most effective antibiotics against P. aeruginosa with the sensitivity of 68.1% and 57.2%, respectively. Conclusions: According to the results, P. aeruginosa had high resistance against antibiotics such as cotrimoxazole and ceftriaxone. Therefore, these antibiotics should be used correctly and reasonably, and epidemiological studies in this regard should be focused on proposing national programs to prevent the further spread of antibiotic resistance.

Published: December 2020

The aim of this paper is to propose a simulation model based on system dynamics and the elements that compose Quick Response Manufacturing (QRM) strategy. The developed model is a very useful decision-making tool, since it facilitates the obtaining of process flow times and lot sizes in manufacturing environments that focus their competitive strategy on markets that demand a high variability and product customization. Through simulating four different scenarios, the effects of variability and machine resources utilization are evaluated. The results show that a minimal change in machine resources utilization causes a high impact on process flow times and consequently, on another critical QRM variable such as Manufacturing Critical-Path Time (MCT).

Keywords: Simulation, System dynamics, Quick response manufacturing, Flow time; Operations management

Bananas are known to contain fiber and vitamins essential for human body. Thus, the ability to detect these of vitamin in bananas is crucial. Information in the vitamin content of can affect procedures for harverst and post-harvest process. Methods to determine the nutrition content of foods are usually carried out using High Performance Liquid Chromatography (HPLC). However, this method requires complex sample preparation and chemical reaction processes. Due to this weakness, alternative techniques are needed to detect vitamin in simple ways. In this study, a simple, easy and fast methods to determine the vitamin content of banana was developed. Using reflectance and photoluminence spectroscopy, the vitamin of bananas from five different species were able to be identified. From the reflectance spectra results, two peaks were observed, the first peak at a wavelength of 325 nm is the absorption peak of vitamin B6 and the second peak at 450 nm is the absorption peak of vitamin B12. From the photoluminence spectra using excitation wavelength at 325 nm, an emission peak was found at wavelength 450 nm which is the peak emission from vitamin B6. These results proved that by using the methods proposed, the detection of vitamins in bananas can be done in an easy and simple ways.

Previous study successfully conducted encapsulation of the purple-fleshed sweet potato’s anthocyanin but the study has yet to reveal the stability of encapsulated anthocyanin. Therefore, this research aims to observe the stability of encapsulated anthocyanin regarding the characteristic of low anthocyanin stability, which depends on environmental factors, such as temperature, pH, humidity, and water activity. The kinetic parameters of stability, including kinetic constant (k), reaction order, and half-life (t1/2), were also studied. Stability testing was conducted in high water activity of 0.75 and various in-cubation temperatures at 16, 25, 35, and 45°C. Un-encapsulated anthocyanin extract was also tested for its stability in the same condition in order to be compared with encapsulated anthocyanin. This study re-vealed that the encapsulated anthocyanin had lower stability than un-encapsulated anthocyanin extract. It was proven by higher kinetic constant and lower half-life of encapsulated anthocyanin for every incubation temperature which was induced by higher pH of encapsulated anthocyanin compared with anthocyanin extract. Besides, high water activity reduced glass transition temperature (Tg), in which encapsulated anthocyanin was in rubbery state. Both encapsulated anthocyanin and anthocyanin extract were degraded following the first order kinetic. Using the Arrhenius equation, it was obtained that the degradation kinetic constant of encapsulated anthocyanin was stated as k= 420.44 exp (-23.33/RT). Meanwhile, k= 1.12x106 exp (-46.70/RT) described degradation of kinetic constant of anthocyanin extract. The stability test re-vealed that the application of encapsulated anthocyanin was not suitable for wet-type food product.
La dialéctica comunitarismo-societarismo detrás del reconocimiento de sistemas de justicia indígenas

Published: December 2020

El presente artículo tiene por objeto el análisis de la Declaración de Naciones Unidas 2007 sobre derechos de los pueblos indígenas, utilizando como paradigma teórico la confrontación conceptual de la cosmovisión comunitaria y societaria. Desde una perspectiva comunitarista se proponen los principios de subsidiariedad y solidaridad debido a su funcionalidad política en Estados descentralizados y plurales, también, porque son especialmente aptos en el caso de pueblos o naciones indígenas dentro de un Estado. Así mismo, se desarrolla teóricamente la idea de pluralismo jurídico y sus implicaciones en la teoría del Derecho y del Estado en el siglo XXI, ya que esta pluralidad de ordenamientos es un rasgo definitorio de la complejidad cultural y jurídica de las sociedades pos modernas.

La fotografía como fuente histórica en el aula. Análisis de una metodología para la enseñanza de la Historia en la Educación Superior
Authors: Ponsoda López de Atalaya Santiago , Blanes Mora Ruben
Published: December 2020

El presente artículo analiza una metodología activa centrada en el uso de fuentes históricas, en este caso la fotografía, para la enseñanza de la Historia en la Educación Superior. La propuesta analizada se llevó a cabo en la asignatura Didáctica de las Ciencias Sociales: Historia del Grado de Maestro en Educación Primaria de la Universidad de Alicante. Los datos obtenidos han sido tratados de forma cualitativa y han permitido conocer, además, la percepción del alumnado ante una nueva manera de trabajar contenidos históricos. Los resultados obtenidos confirman que la metodología que utiliza de forma adecuada la fotografía como fuente histórica incentiva el análisis y la reflexión sobre los hechos tratados y, al mismo tiempo, se convierte en un elemento motivador para la enseñanza de la Historia.
Enfoques para la enseñanza de la Biología: una mirada para los contenidos
Authors: Bermudez Gonzalo Miguel Angel , Occelli Maricel
Published: December 2020

En el marco de un diseño didáctico multirreferencial y contextualizado a necesidades específicas, tomar decisiones sobre los contenidos exige poner en juego conocimientos específicos de la didáctica de las ciencias. Tras relevar el uso del término enfoque en la bibliografía de didáctica de las ciencias experimentales y formación del profesorado, reconocemos como enfoques establecidos a CTSA, la interdisciplinariedad y la historia de las ciencias. Sin embargo, al conceptualizar nuestra postura acerca del concepto de enfoque, asociado a las decisiones que tomamos las y los docentes sobre los contenidos, realizamos un análisis epistemológico y didáctico de la Biología y de propuestas de enseñanza de esta disciplina. Con base en ello proponemos y describimos ocho enfoques más para la enseñanza de contenidos biológicos, que diversifican los tres enfoques anteriores: morfo-funcional, taxonómico-clasificatorio, evolutivo, sistémico y ecológico, educación ambiental y educación para el desarrollo sostenible, diversidad cultural, educación en salud y educación sexual integral

El objetivo del presente artículo es ofrecer al docente de E/LE un análisis de tres herramientas (Crucigramas para imprimir, Educima y EclipseCrossword) para generar los pasatiempos que conocemos con el nombre de crucigramas. Nos centraremos en las variables básicas que este tipo de juego lingüístico ofrece para su configuración, como la elección del número de palabras, de las piezas léxicas en sí, de un campo léxico determinado, del nivel de dificulta o del tamaño de este. El artículo se integra en una serie de análisis y aprovechamiento de diversos pasatiempos en el aula de E/LE, iniciada en trabajos anteriores
Las perífrasis que teníamos olvidadas: revisión y actualización del tratamiento de «tener + participio» y «llevar + participio» en la enseñanza de ELE
Authors: Torres Soler Julio , Bastías Miralles Marta
Published: December 2020

Las perífrasis resultativas  y  presentan una particular complejidad para los aprendientes de español, que se ve agravada por una desatención generalizada en los materiales de Español como Lengua Extranjera (ELE). En este estudio, en primer lugar, llevamos a cabo un análisis del tratamiento que han recibido estas perífrasis en algunos manuales y gramáticas de ELE. Constatamos que, en la mayoría de casos, se han dado explicaciones insuficientes, confusas o excesivamente metalingüísticas de estas construcciones. Tras confirmar la necesidad de actualizar la enseñanza de  y , llevamos a cabo una propuesta de sistematización de su tratamiento basándonos en los fundamentos teóricos de la gramática cognitiva y en los parámetros de la atención a la forma (focus on form). Por último, ofrecemos una secuencia de actividades original para aprender y practicar las perífrasis resultativas de forma significativa.
How prior knowledge, learning, teaching and assessment affect students’ achievements in Mathematics
Authors: Xhomara Nazmi
Published: December 2020

In this study we investigate how prior knowledge, the comprehensive learning approach, problem-based teaching and assessment influence students’ basic-learning skills in Mathematics at the university level. To do so, we employed a quasi-experimental research design and a structured questionnaire. Two experimental groups and two control groups of students were involved. We found a negligible correlation between prior knowledge and basic-learning skills but a positive correlation between prior knowledge and the comprehensive learning approach. On the other hand, we found practically no correlation between prior knowledge and assessment. We also found that problem-based teaching correlated positively and that the traditional approach correlated negatively with prior knowledge. Moreover, prior knowledge, problem-based teaching, the comprehensive learning approach and assessment explained 50% of the variance in the levels of basic-learning skills.
La inferencia cronológica bayesana aplicada a la industria lítica de la Prehistoria Reciente: el caso de estudio de los conjuntos superficiales de las terrazas del valle bajo del río Ebro (Aldover, Baix Ebre)
Authors: Gironès Rofes Ivan , Pardo Gordó Salvador , Molist Montaña Miquel
Published: December 2020

En la zona del valle bajo del Ebro la problemática de los palimpsestos artefactuales líticos ha tendido a emerger en estudios que aportan cronologías relativas rígidas y lineales, con poca rigurosidad y teniendo poco en cuenta los procesos posdeposicionales que afectan a tales conjuntos. Para hacer frente a tal problemática y poder especificar y analizar a un mayor nivel estos conjuntos superficiales, se presenta la aplicación de una nueva metodología utilizada en casos de estudio similares del área valenciana. Ésta se enfoca en la inferencia cronológica Bayesiana mediante la computación para la construcción de modelos formados por referentes crono-tipológicos y contextuales, partiendo des del Epipaleolítico hasta el inicio de la Edad del Bronce (13.400-4.200 cal BP.). Se aplicará a nuestros casos de estudio de conjuntos líticos de superficie provenientes de cuatro áreas: Vall del Llop, Vall de Mantons, Vall de Carrinya y La Conca (Aldover-Xerta, Baix Ebre).
THE ROLE OF ARCHITECTURAL EDUCATION FOR SUSTAINABLE CONSTRUCTION: A CASE STUDY AT UNIVERSITY OF BALIKESIR IN TURKEY
Authors: TÜLÜBAŞ GÖKUÇ Yeliz
Published: December 2020

Today, the concept of sustainability is a very popular topic in the construction sector as in all areas of the industry. When the environmental impacts of the building life cycle are considered, the importance of this concept for this sector is seen more clearly. As in every education field, architectural education is also shaped according to the needs of the age. The differences between 2000s and today can be noticed when looking at the field of architecture that shifts in line with the needs of the age. Thus, necessary changes should be made in some disciplines such as architecture, interior architecture, civil engineering, city and regional planning and landscape architecture under the subject of sustainability. Architecture, which shapes the living spaces, has an enormous responsibility along with some other disciplines during the evolution of the occupational environmental awareness. It should be ensured with the university education that the undergraduate architecture students develop a mentality that pays attention to the concepts of ecology and sustainability, and enables skills to utilize renewable energy sources. This study aims to determine the awareness of students on sustainability. The data for this research is collected by conducting a survey at the Department of Architecture at the University of Balıkesir, and covers the senior students in the spring semester of 2018-2019 and 2019-2020 academic years. This study emphasizes the concept of sustainability, and aims to determine how the architect candidates who will be implementers in the future interact with the concept of sustainability during their higher education. One of the results of the study shows that students do not have much knowledge about sustainable architecture, but they tend to take related courses. Another result of the study is that students should be directed to projects that emphasize sustainability in architectural design courses.
Simulation of the Impact of Waste Batteries on Ecosystem Reliability
Authors: Petrov Alexander , Pohrebennyk Volodymyr , Shybanova Alla , Ruda Mariia
Published: December 2020

To assess the impact of not just the battery as such but its multi-element composition on the state of the environment, a new approach is proposed through the determination of the reliability of ecosystems, which makes it possible to obtain quantitative indexes of the stability and losses of natural ecosystems. These data can be used as indicators of the state of the environment, and hence as the assessment of an environmental component that is important for determining the actual impact of the multi-element composition of batteries. On the basis of such indicators, which can be obtained using the SimaPro software, it is possible to calculate thresholds beyond which negative phenomena occur, as well as to predict and simulate situations, to carry out the mapping of sources of risks, to monitor changes, and this will allow identifying the causes of these changes or determining the factors that slow down or retard the approach of ecosystems to a critical state, i.e. to develop preventive measures to avoid disasters. The eco-indicator 99 is one of the methods that allows us to accept one estimate for the whole product - the so-called ecological index. It is the sum of all individual eco-points or partial indexes for all life-cycle processes. The computational procedure is carried out by summing up the results of weighing the phases of the life cycle.

Authors: Basiura Beata , Motyczyńska Joanna
Published: December 2020

Portfolio analysis is a tool particularly intended for investors. Risk assessment and risk specification make the investor able to properly diversify and offset the portfolio. Broadly speaking, there are multiple tools destined for building up an efficient set of portfolios.One of them is Markowitz’s model theory postulating building up a portfolio determined on the basis of equilibrium between expected profit level as well as accepted level of risk assessment.In the context of this paper, the objective is to shed some light on creating investment portfolios based on either Markowitz's portfolio theory or evolutionary algorithm. The simulation based methods for building up a portfolio of approximately 40-50 companies listed out in the primary marketof the Warsaw Stock Exchange using the selection function proposed in the BA thesis were presented.Portfolio profit values have been evaluated in a dynamically shifted time window. The conducted analysis showed shifts in the economy at certain periods of time. The implemented genetic algorithms smoothly handled the optimization with a relatively short processing time of the task result.
