History says that design is actually rooted in artistic activities that have grown towards one sphere of culture in its essence to another: the means of everyday human life. When historical descriptions state that the primitive people make cangulals as a tool that is a transformation of the extension of the hand: often questions about design, art or technology. Design is challenged to have to engage in a variety of cultural weather.  As with technology, design is required to immediately formulate the situation in line with the development of other cultural sectors. The construction of the Bauhus in Germany, with the prophecy of Walter Gropius, is considered a milestone in the development of modern design history. The basic philosophy of the Bauhaus departs from the idea that the methods of industrial production of the 19th century have led to the disregard of the relationship between the process of design and handicraft or the ability of the hand, the unity between the creator and the product is broken. In fact, the influence, the Bauhaus principles that later evolved into an International style, were not the product of experiments produced by the instructors (Meister) and his students, but the methodology of visual arts education and the design methodology that he taught. The fundamental role of a designer will never change, but what will change is his commercial situation. Technology, research, and manufacturing techniques of different products drive manufacturers to produce similar items. Keywords: History; Product Design; Design Role
Communication Willingness Factors Between Project Stakeholders in the Construction Industry
Authors: Perrenoud Anthony , Gardner Heather
Published: December 2023

Effective communication is a critical component of project management and, as a result, an essential component of the construction business. Construction project teams present unique communication challenges with the multidisciplinary makeup of members that have different communication styles with varied levels of understanding, skills, and adaptability. Past research has been fragmented with understanding the factors that promote communication between contracting parties. This study identifies ten factors that impact communication willingness and tests the level of impact of each factor. Additionally, industry practitioners were surveyed on the factors impact on communicating with other project stakeholders. Fifty-three individuals were surveyed in the South-Central region of the United States, representing four different project stakeholders: owners, architects, project managers, and superintendents. A personal desire to succeed and communicating with skilled individuals were found to be the motivators that had the greatest impact on promoting communication willingness. One-way analysis of variance (ANOVA) was used to identify three differences with communication willingness between the different project stakeholders.
Extracting BIM data to support a machine learning model for automated clash resolution
Authors: Harode Ashit , Thabet Walid
Published: December 2023

Clash resolution is considered a critical step to resolve issues among the different disciplines for a construction design to be realized as expected. This step, however, continues to remain slow and manual which can significantly delay a project and drive-up costs. A combined machine learning model was proposed by Harode and Thabet (2021) to automate the clash resolution process. A large amount of labeled dataset is required to train and test the proposed model. The dataset is planned to be extracted from various industry-provided federated construction BIMs. Federated construction models are created from multiple subcontractor component models authored using different software. As a result, data is stored in various formats using different data structures making the extraction process difficult. In this paper, the authors demonstrate the use of commercially available software tools including iConstruct, Dynamo, and Talend to overcome this limitation and extract the necessary data. The paper first defines the required data structure followed by a data extraction process to capture required data from clashing elements in the federated BIMs. The paper also discusses a novel method of extracting end point coordinates and moveable area for clashing elements using bounding boxes. The paper concludes with future research directions.
Synergizing Case-Based Learning and Industry Involvement in a CEM Course – A Case Study
Authors: Franco Duran Diana , Gutierrez David
Published: December 2023

This paper synthesizes the lessons learned from the experience of developing and teaching a Case- Based Learning (CBL) course in Construction Engineering and Management (CEM) with a diverse group of industry partners. The authors analyzed and compared the participants' reflections on their experiences throughout the course to identify: 1) the factors that may foster and hinder students' learning and 2) potential opportunities and challenges of interacting with industry practitioners when using CBL as the core teaching strategy in a CEM course. While structuring the course, instructors should invest time in increasing the navigability of practitioners' supplemental material and guiding students through it. Case order matters –complexity and uncertainty should increase as students gain confidence with CBL—and including deliberate team preparation time was highly welcomed by students. Practitioners' presence in the classroom increased case credibility, which resulted in more self-reported student engagement. Welcoming more actors allows students to analyze the cases from diverse points of view. Instructors should act as discussion facilitators. Looking forward, practitioners should start documenting the alternatives considered beyond the definitive solution of a case to enrich the case's contents. These outcomes provide instructors interested in implementing CBL in their engineering courses with insights grounded in experience that will ease the process from ideation to delivery.
Effect of Competency Grading in Statics and Mechanics of Materials Course on Student Grades in Follow-On Course
Authors: Davis Kirsten
Published: December 2023

Competency grading is a non-traditional grading style that focuses on the proficiency of the learner. It has been proven in other studies to be an alternative grading system that works well in technical courses and has a lot of benefits for both the student and the instructor. The results of the data analysis for this study indicate that the mean grade in the follow-on course entitled “Introduction to Concrete and Steel Design” is higher when competency grading is used in the prerequisite course “Statics and Mechanics of Materials” than when traditional grading is used. The competency grading style helped students be more successful in the follow-on course than students taught with a traditional grading style because of changes to both student and instructor behaviors. Lessons learned are also included for faculty interested in considering adopting competency grading in their courses.
Open-Resource Examination: Merits of an Alternative Approach to Student Assessment
Authors: Killingsworth John , Besiktepe Deniz , Tummalapudi Manideep
Published: December 2023

Traditional examination methods are not always sufficient for measuring a student’s knowledge, skills, or abilities on a given subject. These traditional exams also create sufficient anxiety for the student to warrant the exploration of alternative assessment methods. Open-resource examination was explored in this longitudinal study that spans a six-year timeline in a construction finance course. The use of an online application to design, administer, and grade was considered in this study. This was accompanied with a survey of the students. Exam results as well as survey results are presented and discussed in this paper. Descriptive statistics were used to evaluate the results over the timeline of the study. Advantages to students include reduced exam anxiety, immediate results, and control of exam location and environment. Advantages to instructors include automated grading as well as statistical analysis of individual exam questions and aggregate performance. Additionally,both instructor and student gain valuable class-time to treat content and context of the subject. Limitations of open- resources exams are also considered. The results make a compelling case for a broader implementation of open- resource, online exams.
A Review of Social Sustainability Studies Involving Multiple-Criteria within the Construction Industry
Authors: Passos Neto George D. M. , Alencar Luciana H. , Valdes-Vasquez Rodolfo , Ozbek Mehmet E.
Published: December 2023

This paper explores future research directions on social sustainability in the construction industry through a systematic literature review of studies focusing on multiple criteria. The analysis involved 36 studies identified through the Web of Science, ScienceDirect, and Scopus. The results uncovered how social sustainability assessment is conducted, and where the studies are taking place, mostly in developing countries. On average, the reviewed studies used 29 criteria to assess social sustainability. That large number of criteria indicates a need to find a subset of criteria capable of representing social sustainability complexity. Regarding the methods identified, Multicriteria Decision-Making/Aiding (MCDM/A) methods are the most used, including the Analytic Hierarchy Process (AHP) and weighted aggregation. However, it is difficult to confirm if they are the most appropriate since the authors did not mention how these methodologies were selected or the decision-makers’ rationality, which is necessary for choosing the proper MCDM/A method. Thus, future studies in social sustainability should focus on: i) dimensionality reduction and ii) the structure of the decision problem to correctly choose the decision method. These two recommendations will add to the body of knowledge, especially to the value of integrating the social aspect of sustainability in construction.
Measuring Embodied Energy, Carbon, and Embodied Water of Construction Materials: A Case Study of University Building
Authors: Dixit Manish Kumar , Pradeep Kumar Pranav
Published: December 2023

Buildings consume nearly 40% of the global energy supply and 16% of fresh water annually in their construction and operation, resulting in 39% of the global carbon emissions. Looking at the rate at which the global climate is changing, reducing energy and carbon impacts as well as water use of construction is essential. This paper presents input-output-based hybrid models to analyze embodied energy (EE), embodied carbon (EC), and embodied water (EW) of fourteen construction materials and a university building. The results indicate that the total EE, EC, and EW values of the university building are 4.5 MBtu/ ft2, 528.7 kgCO2/ft2, and 1,049.6 gallon/ft2, respectively. These results emphasize the extensive energy, carbon, and water impacts associated with building construction, which must be addressed. The intensities of total EE and EW of the construction materials vary in the range of 0.1-11.0 MBtu/ft2 and 2.2-134.3 gallon/ft2 indicating water use as an important indicator for material selection. The EC and EW values share a strong positive correlation at the building level, which weakens at the material intensity level. Findings highlight the significance of selecting materials based on not just energy and carbon impacts but also embodied water use.

Published: December 2023

Delays with project completion and turnover is a global problem affecting construction and industry partners in many areas. These delays impact both planning and budgeting which are serious concerns for all stakeholders involved and difficult to resolve and overcome. The focus of this research paper is limited to only Military vertical construction projects executed by the Fort Worth District and specifically, the analysis of their associated construction durations. Construction performance data from the United States Army Corp of Engineers (USACE) SWF Primavera Project (P2) database was utilized in this study. The raw dataset covered the period of 2003 to 2021 and included a total of 4,435 projects. This dataset was reduced down to focus only on the 173 Military vertical construction projects executed by the USACE Fort Worth District and completed between the years of 2006 and 2020. The results of this research provide the USACE Project Delivery Team a better understanding of lessons learned and utilization of a more accurate method for establishing construction project durations for USACE projects.
Knowledge and Skills Required for NZEB Project Construction
Authors: Rahman Muzibur , McCuen Tamera
Published: December 2023

Efficient project management is crucial to project success. As the construction industry changes, constructors face new issues and must undertake roles that have not traditionally been part of their responsibility. The aim of this study was to identify the Net Zero Energy Building (NZEB) project management challenges, and to determine the knowledge areas and skills that are necessary to respond to those challenges through surveys and interviews with NZEB constructors. NZEBs consume less resources than produced during operations of the building. Results revealed that the most important challenges were a general unawareness of the correct methods and procedures, reluctance to change from traditional practices, and the lack of the technical skills with NZEB technologies. The most important knowledge areas identified were communication management, schedule management and planning, and cost management. The most important skills were teamwork, leadership, and problem-solving. In addition, this study provides a summary of the importance of the various mechanisms for professional constructors’ development of net zero construction knowledge and skills. This study is beneficial for the constructors’ decision making in the NZEB project context. Educators are also expected to benefit from this study in the development of academic curriculum with a goal to meet the need.

Published: December 2023

Similar to other injury-prone industries, the construction sector experiences an elevated number of accidents regularly. These inauspicious occurrences mostly lead to unwanted variability in project performance indicators and exert negative impacts on the victims, their families, and society. The major causes of accidents in the construction industry have often been linked to human factors, particularly the lack of adequate safety and health education in tertiary institutions. This study evaluates safety and health education in the curricula of construction-related programs in Nigeria. First, accredited construction-related programs in Nigerian universities were identified after which the curricula of 14 selected programs were examined to determine safety and health education provisions. Thereafter, a survey was designed and administered to faculty from six universities (one per geopolitical zones) to investigate their perception of the barriers and drivers to the inclusion of safety and health education in the curricula of construction-related programs. Findings from the study revealed the existing lack of construction safety and health education in the curricula and the main barriers/drivers impacting inclusion in Nigerian construction programs. These findings could be used to develop a framework and strategies for integrating construction safety and health education into the curricula of construction-related programs in Nigeria.
Training about Drone Safety Challenges in Construction using a 360 Virtual Environment: Analyzing Learning Effectiveness
Authors: Cheng Jiun-Yao , Gheisari Masoud , Jeelani Idris
Published: December 2023

Utilizing drones on construction sites could put workers who are already in dangerous environments into even more risky situations. Therefore, researchers have explored the safety challenges and their countermeasures regarding drone integration into construction sites. This study proposes using a 360- degree virtual reality (360VR) training environment to educate construction professionals on the safety concerns that drones could pose and how to work safely on a drone-populated site. This study specifically focuses on the knowledge gap of how trainees’ backgrounds, such as construction experience, work experience with drones, and prior understanding of drones, could be associated with the effects of the training. This study created comprehensive pedagogical intervention content using 360VR, followed by a user-centered pre- and post-experiment. After training, participants’ knowledge levels improved by 41% on average. Furthermore, the results indicate that trainees’ construction experience and job experience with drones were not associated with their knowledge levels. Moreover, those with lower levels of understanding about drones significantly improved their knowledge scores after the training. The result shows that trainees with different knowledge about drones may be suitable for trainings with different levels of difficulty.
Why are School-Leavers Pursuing A Higher Education Degree Rather Than Joining A Skilled Trade in Ireland
Authors: Byrne Luke , White Joanne , Curran Michael , Meekal Sonya
Published: December 2023

The purpose of this research was to investigate the main influences on school-leavers’ decision to pursue a career path in the construction industry through either a higher-level degree or a skilled trades program in Ireland. Additionally, this study examined how the key influencers on school-leavers, such as parents, teachers and career counsellors view the construction sector. The research applied a mixed- methods research approach. A survey was conducted among 200 mainly 6th year school-leavers across four secondary schools in the Wicklow and Wexford areas in Ireland. Through a questionnaire data was collected about their reasons for deciding on a higher-level degree compared to a skilled trades program. The influencers’ perspective on the construction sector was assessed through semi-structured interviews, enabling triangulation of the data. The findings indicate that most school-leavers were given more information about higher education options than apprenticeship. Furthermore, the research suggests that most school-leavers believed that higher education is considered a superior pathway over joining skilled trades courses. School-leavers see apprenticeships as a lesser achievement than higher education. There is a need to address negative stereotyping associated with apprenticeships and to inform students in secondary school early about the alternative study pathways and career opportunities.
Materials Delay Impact due to COVID-19 on Construction Projects
Authors: Sulbaran Tulio , Kisi Krishna
Published: December 2023

Exposure to wildfire-related smoke has serious implications for the health outcomes of outdoor occupational workers. As wildfire season is becoming more prolonged in California, outdoor building construction workers are at great risk of exposure to particulate matter (PM2.5) pollution caused by wildfire smoke. Wildfire smoke PM2.5 exposure has been shown to result in short-term health impairments, missed workdays, and long-term disease progression. Studies highlighting the exposure of outdoor building construction workers to wildfire-related PM2.5 is limited in the existing literature. Using historical wildfires data, employment data of outdoor building construction workers, and air quality data for PM2.5 pollution from 2010-2020, this paper investigates the potential exposure of outdoor building construction workers to wildfire smoke PM2.5 in California. Counties which experienced wildfire events were identified by intersecting wildfire perimeters with county boundaries using the geospatial analysis software ArcGIS. Monthly employment during wildfire months and the number of days when the PM2.5 air quality reached unhealthy levels during those months were evaluated to find the worker smoke exposure days of each county. Results show that outdoor building construction workers in California are vulnerable to wildfire PM2.5 exposure and associated health risks, as the typical wildfire season aligns with peak seasonal construction work.
Why are tradeswomen leaving the construction industry: An Exploratory Study
Authors: Tummalapudi Manideep , Doke Ninad , Gunderson David , Malla Vijayeta
Published: December 2023

The construction industry in the United States is currently undergoing historic shortage of skilled workforce. Several research studies have suggested to attract, recruit, and retain women in construction trades to address some of the workforce shortages in the future and also to improve jobsite productivity. Despite undertaking efforts in this direction to improve recruitment and retention of women in trades, it is observed that several women either left or considered leaving construction trades at some point in their careers. Previous studies focused on issues specific to women in administrative, managerial and leadership roles, however there is very limited knowledge relevant to issues of tradeswomen. This study exclusively focuses on tradeswomen and investigates the causes that influences tradeswomen to leave the construction industry with an intent to develop recommendations to improve their retention. To achieve the objectives, this study conducted twelve qualitative interviews with tradeswomen working in a variety of trades. The study identified important factors such as male dominant culture, inadequate attention from employers regarding tradeswomen issues, workplace and sexual harassment, discrimination such as pay imbalances, improper facilities, and misfit PPE Furthermore, recommendations for employers and industry organization were provided to improve tradeswomen retention. Understanding tradeswomen challenges helps improve their retention thereby improving the diversity in construction industry and contributes to the success of tradeswomen.

Authors: Mirando Anthony , Onsarigo Lameck
Published: December 2023

The proliferation of mass timber structures across the United States has begun. So much so, a comprehensive evaluation of key building attributes and identification of trends in built structures can be measured. This study utilizes a comprehensive market analysis of existing commercial mass timber structures to quantify important attributes to gain au fait and establish a baseline dataset. Specific interest lies in key areas, sustainability certification frequency and type, location, size, cost, and construction type. This study deploys descriptive statistics to evaluate 229 completed mass timber commercial projects across the United States. The study draws linkages and observes relationships between sustainability rating systems and mass timber structures, geographic concentrations, project cost, project size and height, building type, and building location. The expansion of mass timber is highlighted by the fact that nearly 80% of states across the country are home to a commercial MT building, with an average price per square foot of $344.89, and sustainability rating presence in over 30% of projects.
Quantifying a Scoring Limitation of a Federal UAS Flight Proficiency Exam
Authors: Burgett Joseph , Dees Colin
Published: December 2023

To operate a drone in the U.S., the federal government requires pilots to pass a standardized Federal Aviation Administration (FAA) knowledge test. The government does not require drone pilots pass a practical exam demonstrating minimum flight proficiency. However, the government, through the National Institute of Standards and Technology (NIST), has provided a voluntary exam protocol to test flight skills. Using the NIST exam protocol, the Airborne Public Safety Association has created the only nationally recognized unmanned aircraft systems flight proficiency certification. This certification is frequently used by contractors and construction UAS courses. The literature has identified a limitation in how the exam is scored. The purpose of this study is to quantify how impactful this limitation is. The researchers conducted an experiment administering the exam to 24 licensed drone pilots. The exam was scored compensating for the scoring limitation. The study found that when the scoring limitation was accounted for, scores

were inflated by approximately 5% with inexperienced pilots. Inexperienced pilots will have the highest deviation and represent the most extreme cases. Given the relatively low 5% deviation with novice pilots, the study found that this limitation is not a significant concern and can be managed by the exam proctor.
Ageism: A Threat to Career Progression Despite Labor Shortage in the Construction Industry
Authors: Kereri James , Nyang'Au Getrude
Published: December 2023

Considering the degree and rate of aging of construction workers around the globe, which is compounded by intensifying labor shortages, the industry requires serious attention to workplace policies that safeguard older workers against ageist stereotypes and prevent early retirement while at the same time attracting younger workers. Ageism has been identified as a barrier in all four layers of career progression (recruitment and hiring, retention, promotion, and firing/dismissal). Therefore, the steps to tackle ageism in the construction industry need to include a strategy that ensures the career progression of older and experienced workers, and an approach that welcomes a more diverse young workforce. Through a comprehensive literature review, this research sought to explore the current state of ageism in the construction industry. The findings of this research show that even though minimal research has been conducted thus far, there is a strong business case that justifies further research in this area. Research findings further point out to ageism as a threat in career progression. Sources of ageism barriers include societal and employer attitudes, coded language, and worker self- directed ageism. This research recommends both quantitative and qualitative analyzes of the prevalence and impacts of ageism in the construction industry.
El impacto de la geografía sobre la riqueza: autocorrelación espacial, movilidad regional, esquemas convergentes y dinámica temporal del ingreso per cápita, en México
Authors: Guerrero Compeán Roberto
Published: December 2023

La necesidad de definir una visión estratégica del desarrollo en el nuevo entorno nacional ha generado un replanteamiento de los enfoques y métodos de la ciencia regional. Este nuevo enfoque se ha traducido en un amplio debate dentro del contexto de interpretación de las nuevas realidades y en la importancia de lo territorial. ¿Bajo qué condiciones se ordenan los patrones de aglomeración? ¿Cómo hacer para que las externalidades generen un patrón de regiones que maximice los beneficios y minimice los aspectos negativos de la concentración? ¿Debe el Gobierno apoyar únicamente el desarrollo de las regiones más competitivas o las más deprimidas o, por el contrario, establecer un nivel de servicios homogéneo para todo el territorio? ¿Cuál es la probabilidad de que una región próspera entre en crisis, en el futuro?; más aún, ¿cuántos años le tomará a una región pobre convertirse en un centro de desarrollo?El objetivo de esta investigación es determinar cómo los factores geográficos pueden integrarse a la dimensión temporal a través de la evolución de la distribución del ingreso por habitante, a partir de la evaluación de la movilidad de las regiones. En principio, y sin considerar al espacio como una dimensión, esta metodología se aplica a las 2,442 áreas geoestadísticas municipales de México para el periodo 1984-2004, por la vía de métodos no paramétricos, con la finalidad de estimar -al igual que Quah [1996a], Neven y Gouyette [1995], López Bazo et al., [1999] y Maurseth [2001]- funciones de densidad del ingreso normalizado, para luego determinar su transformación en el tiempo.Tanto la trayectoria individual de cada municipio como su movilidad en el seno de la distribución, serán estudiadas utilizando matrices de transición asociadas a las cadenas de Markov. La movilidad regional y los esquemas convergentes son analizados para calcular diversos índices de movilidad y la distribución ergódica.
¿Es la política social una causa de la informalidad en México?
Authors: Esquivel Hernández Gerardo
Published: December 2023

Levy (2008) ha sugerido que la expansión de programas sociales no focalizados, podría inducir un aumento en la informalidad económica en países como México. Sin embargo, esta hipótesis parte del supuesto de la existencia de mercados laborales integrados y competitivos en una economía. En este trabajo, se hace una prueba empírica de dicho supuesto para el caso de México y, se encuentra evidencia de que existe un premio salarial en el mercado laboral formal, es decir, que individuos con características similares ganan más cuando trabajan en el sector formal de la economía que cuando lo hacen en la informalidad. En ese sentido, se concluye que dado que el mercado laboral en México está segmentado, por lo tanto, el aumento en los programas sociales no estaría dando lugar a aumentos en la tasa de informalidad en el país.

Authors: Domínguez Viera Marcos Esaú
Published: December 2023

En este artículo se estudian los efectos económicos del Programa Oportunidades, el Programa de Atención al Adulto Mayor (PAAM) y el Programa de Apoyo para las Personas con Discapacidad (PAPD) en el estado de Nuevo León, a través de un Modelo Lineal, aplicado a una Matriz de Contabilidad Social del año 2004. Los principales resultados revelan que por cada peso que aporta, Oportunidades es el que más beneficia el ingreso de los hogares y la economía de Nuevo León. Considerando los montos totales transferidos, el PAAM genera mayores efectos económicos sobre todos los hogares y el Estado; y el PAPD es el más focalizado en los hogares pobres. El Análisis de trayectorias reveló que el ingreso transferido es gastado principalmente en Alimentos, bebidas y tabaco, que para producirlos se requiere de productos del sector de Agricultura, ganadería, silvicultura y pesca, que a su vez demanda el principal tipo de trabajo provisto por los hogares pobres: Trabajadores agrícolas. Palabras clave: programas sociales, matrices de contabilidad social, modelos lineales de flujo circular de la renta, multiplicadores contables, análisis de trayectorias.JEL classification: D57, H59, R15.

Empleo, escolaridad y sector informal en la Frontera Norte de México y Chihuahua: expectativas de ocupación en la crisis
Authors: Huesca Reynoso Luis
Published: December 2023

El trabajo muestra un análisis de la distribución de los ingresos y las expectativas de ocupación para dos grupos de trabajadores, uno en la Frontera Norte de México y otro en Chihuahua, durante el año de la crisis de 2009 hasta 2011. El objetivo es determinar si las oportunidades de obtener un trabajo formal en esta región mejoran los ingresos de sus trabajadores que se desempeñan como informales. Se observa una mayor participación del trabajo informal por cuenta propia y los asalariados, con un nivel menor en Chihuahua (33%) y superior en la Frontera (46%), ambos por debajo del nivel nacional (50%). La situación mejora en ambas categorías laborales con excepción de la de por cuenta propia en Chihuahua. Lo relevante es que a partir de los 50 años de edad, el trabajo por cuenta propia es un destino probable en la Frontera (40%), no así para Chihuahua que reduce su probabilidad a la mitad. La evidencia final es que la escolaridad sí ayuda a no participar como informal (80%), en calidad de asalariado, cuando se cuenta con estudios universitarios. Clasificación JEL: C14, C25, J24, O17.

A chromosomal analysis of three breeds of Iraqi sheep (Karadi Arabi and Awassi) has been performed on peripheral lymphocytes. The modal chromosome number of all the three breeds was found to be (2n=54XX/54XY) for femal and male respectively. 

The karyotype of Awassi differ from the rest of the domestic sheep (Ovis aries) by the presence of a pericentric inversion on one copy of chromosome number 3. 

Basal minimal medium supplemented with foetal bovine serum was the most suitable culture medium to produce sufficient mitotic cells for chromosomal analysis.

Single cell protein was used to replace 0,7,10,13 and 16% of soyabean meal in diets for broiler chicks up to 51 days of age. In presence of 4% fish meal, ethanol yeast (SCP) could be added at 10% in broiler diet at age 1-24 days and 13% in the diet at age 24-51 days. Chicks given the diets containing 10 and 13% SCP grew significantly (P<0.01) faster than those given 0,7, and 16% SCP. There were significant (P<0.01) differences in the efficiency of feed conversion among different groups.
Adolescentes mujeres en conflicto con la ley penal: patrones de eventos biográficos
Authors: Rebollo Gómez Sara Belén , Martínez Mercado Arnaldo
Published: December 2023

Este estudio cualitativo de diseño etnográfico se condujo con el objetivo de analizar patrones de eventos biográficos de las adolescentes en conflicto con la ley penal, del Centro Educativo “Virgen de Fátima” de Asunción, Paraguay. Los datos fueron recogidos entre agosto del 2022 y enero del 2023. Se aplicaron entrevistas semiestructuradas a 8 adolescentes que estaban en el Centro, durante el período del estudio. Las entrevistas fueron registradas en notas de trabajo de campo, omitiendo cualquier dato de identidad personal. Mediante las mismas se reconstruyeron y compararon las trayectorias vitales de las entrevistadas. Los datos muestran eventos que se dan según patrones de notable similitud. El trabajo categoriza estos eventos en predisponentes y circunstanciales. Los primeros, que ocurren en los años tempranos de la infancia, crean condiciones de vulnerabilidad que predisponen a las adolescentes a que, cuando acaezcan otros eventos vitales posteriores (circunstanciales), entren en conflicto con la ley. Se puede interpretar, aplicando la teoría de la anomia, que los eventos predisponentes impiden la asimilación de las normas sociales por ausencia o carencias del grupo socializador primario.
La ortodoxia del modelo económico clásico y neoclásico: en hombros de gigantes
Authors: Barrera Escobar Alejandro
Published: December 2023

The objective of this reflection article is to vindicate great thinkers in economics who shaped the main theoretical postulates, philosophy and methodology of science, exposing their conceptual and theoretical framework for a comprehensive understanding of their most relevant contributions. In the development of the article, a historical description of the evolution of orthodox economic thought is offered, within a framework of analysis of recognition of economic doctrines from their historical, institutional, political, cultural and social situation, where their contributions are still significant for the interpretation of current reality, not in an absolute way due to the limitations of the assumptions, methods and historical interpretation of the authors, but with inputs that, objectively analyzed, provide validity and usefulness to economics professionals, and in general to all social scientists, for the exercises of positive economics of description, analysis and systematization of economic phenomena and of normative economics of intervention of reality through economic policy. The historical framework of the exhibition is until the 19th century, keeping in mind that, if the economy was built from classical and neoclassical orthodoxy, the alternative and subsequent currents are necessarily heirs, direct or indirect, of these giants of thought.
