Swar NMS, Mohamed AHW. 2018. Incorporation of dietary palm date seeds in all-male Nile tilapia (Oreochromis niloticus) diets. Nusantara Bioscience 10: 193-202. The study utilizes a 45-days randomized factorial design 3×2, three levels (25, 50 and 75%) of palm date seeds, three levels (non, with and without) of 3% bakery yeast (Saccharomyces cerevisiae) and three replicates. The observation was carried out in twenty-one plastic aquaria. All-male Nile tilapia (Oreochromis niloticus) fingerlings were put in each aquarium. Each aquarium was provided with well-aerated and triggered dechlorinated tap water with an average weight of 1.9±1.11 g/fish (10 fish/aquaria) and a total length of 5.18±0.69 cm/fish. Fish were given food three times/day (10 days, at 8.30,11.30, 3.30 A.M) at a rate of 12, 8 and 4% of body weight, to examine the impact of partial substitution of animal protein (fish meal) in the diet on growth achievement, carcass contexture, feed utilization, condition factor (k) and feed expense. Seven experimental diets were prepared; control diet (T0, CP 36.84) concluding 45% (fish meal) as animal protein and 0% (palm date seed meal) plant protein. Tested diets (T1, T2 and T3) concluding 25, 50, 75% with 3% bakery yeast (CP 35.71, 35.53, 34.74) and 25, 50, 75% without yeast (CP36.01, 36.27 and 35.57) respectively ; so, they substitute about 75, 50, and 25 of fish meal diet respectively. The outcomes showed that, tilapia were given food on T1, T2 and T4 diets (25, 50, and 25%) substitution with and without yeast respectively registered the greater growth achievement, feed and protein utilization than other experimental diets such as control diet, also they indicate the highest condition factor (K) grades which state that the fish are in decent health. Tilapia were given food by diet T3 (25% fish meal) T5, T6 (50 and 25% fish meal) with and without yeast respectively possessed deficient growth and diverged remarkably (p>0.05) from the other diets. Diet contexture remarkably had an impact on carcass contexture. These data prompted that Palm date seed with and without yeast S. cerevisiae can, to a certain extent, substitute fish meal (animal protein) in a diet for all-male Nile tilapia fingerlings at level-up to 50 and 25% with and without yeast respectively, without any unfavorable result on accretion achievement. Furthermore, fish diet, partially substituted with 3% yeast, resulted from superior accretion achievement than other diets within the present experimental circumstance. This study showed that there is an economic efficiency of confounding palm date seed (plant protein) as partial substitution of fish meal (animal protein) with and without yeast in all-male Nile tilapia, that it could decrease the expense of feeds.

Huang CH, Adeni DSA, Johnny Q, Vincent M. 2018. Production of bioethanol from sago hampas via Simultaneous Saccharification and Fermentation (SSF). Nusantara Bioscience 10: 240-245. Sago hampas is an inexpensive, renewable and abundant agro-industrial residue that can be exploited to produce bioethanol. In this study, ethanol production was performed via simultaneous saccharification and fermentation (SSF) on fresh sago hampas at 2.5%, 5.0% and 7.5% (w/v) feedstock loadings with the aid of amylolytic enzymes, cellulolytic enzymes and Saccharomyces cerevisiae, under anaerobic condition for five days with a constant agitation of 150 rpm and ambient temperature. Results obtained indicated that SSF with 5.0% (w/v) sago hampas loading produced the highest ethanol yield at 17.79 g/L (79.65% Theoretical Ethanol Yield, TEY), while SSF using 2.5% and 7.5% (w/v) sago hampas produced ethanol at only 8.38 g/L (75.00% TEY) and 23.28 g/L (69.48% TEY), respectively. Total biomass reduction was recorded between 66.3% to 71.3% by the end of the SSF period. This study demonstrated that fresh sago hampas is a promising feedstock for bioethanol production as yields are generally high for all the substrate loadings tested. Moreover, bioethanol production using fresh sago hampas may assist in reducing pollution caused by sago waste accumulation.
Supporting parent–child bonding through relationship-based community music programmes: Description of an Elemental Music Pedagogy programme with young, at-risk mothers and their children
Authors: Savage-Kroll Camille
Published: February 2019

Through numerous studies in the field of brain and learning research we know that the first years of a child’s life play a crucial developmental role and that actively engaging with music in these early years can have positive effects on overall development. Music addresses all aspects of intelligence – the cognitive, emotional, social, mental and the spiritual. It touches, unites and encompasses every facet of being human. Attachment Theory emphasizes the primary importance of secure bonding and attunement in children’s development. In Germany, parent–child music groups have boomed since the 1990s. In recent years there has been a movement in the area of Elemental Music Pedagogy towards creating community music groups for parents of babies or young children with the explicit goal of strengthening the parent–child bond. In partnership with organizations supporting young mothers in hardship, music courses are being developed and offered for this specific group. This article aims to present the theoretical groundwork of such groups and examines recent practical examples.

Puissance auto-affective et pathétique de l’écriture poétique
Authors: DUBOIS Matthieu
Published: February 2019

Henry Bauchau se dit « écrivain par espérance ». L’extrême-Orient, chez lui, incarne une voie où peut se renouveler une certaine spiritualité, liée à la déprise des certitudes idéologiques et un retour à l’émerveillement de la condition incarnée, lieu de notre finitude comme condition d’un épanouissement de soi. La puissance auto-affective et pathétique de la parole poétique fonde donc ce que l’on peut appeler une « poéthique », c.-à-d. une esthétique dont l’horizon est la transmutation de la violence de l’éprouver en puissance afin d’accroître le potentiel de vie du sujet tant scripteur que lecteur. C’est ainsi que la vie peut révéler sa puissance originaire d’adhésion à elle-même, laquelle correspond à une puissance d’amour, par-delà la rugosité inhérente de l’existence.

The Experience of Completing an Undergraduate Nursing Honors Research Project on the First Professional Nursing Position
Authors: Antior Katlyn R. , Pugh Antoinette K.
Published: February 2019

Undergraduate research experiences have become a hallmark of excellence in degree programs in the science, technology, engineering and math fields, with indications that these experiences lay important groundwork for graduate education and practice in the field. In nursing, several schools offer undergraduate nursing research experiences, though there is scant research related to outcomes among nurses at the baccalaureate level. Since evidence-based practice (EBP) is becoming increasingly important in health care, the use of research-related skill sets has become more critical for practicing nurses. The benefits of undergraduate research experience have been inadequately studied and there have been no nursing studies on the impact of undergraduate nursing research experience on the practicing registered nurse. At a research intensive public university, a robust honors program exposes students to research throughout the baccalaureate degree, with student engagement in every step of the research process alongside faculty research mentors. The purpose of this study was to qualitatively explore the experiences and outcomes of participation in a significant undergraduate research project on the first few years of nursing practice as an RN. Data analysis was conducted using an open coding method to analyze the responses of the participants and aid in the process of identifying major themes that express the phenomenon. Through this approach a descriptive analysis of the experience of completing an undergraduate research project was completed, including the impact on the nursing practice and development of the participants in their early careers. The results suggest that extensive exposure to research in undergraduate schooling increases the level of self-confidence in the first nursing position. Participants also felt that they stood out from their peers. Other benefits include expanding knowledge regarding the research process, improving writing and public speaking skills, and advancing personal and professional development.
Parasite Selection and the Fitness of Sexual Reproduction
Authors: Klosak Samantha A.
Published: February 2019

Sexual reproduction is a very costly process: the growth rate of asexual lineages exceeds that of sexual lineages. Nonetheless, sex is prevalent in nature. The Red Queen Hypothesis argues that, because sex and recombination generate genetically variable offspring that may escape infection by coevolving parasites, parasites select for sex in hosts (Lively & Dybdahl, 2000). Our research directly tests if the Red Queen can explain the maintenance of sex in a natural population. This experiment focuses on a natural population of the snail Potamopyrgus antipodarum, which is native to New Zealand. Individuals of this species are either diploid and sexually reproducing or triploid and asexually reproducing (Lively & Osnas, 2006). This snail is naturally infected by the trematode parasite, Microphallus, which is sterilizing and thus exerts strong selection on its host. The Red Queen Hypothesis predicts that parasites should periodically increase the fitness of sexual relative to asexual individuals. We accordingly established mesocosms containing both sexual and asexual snails from the same natural population. Half of these mesocosms were exposed to parasites and the other half were not. These snails were then allowed to reproduce over the course of a year. We used flow cytometry to determine the frequency of diploids in the parents and the offspring, and thereby the fitness of sexual individuals in the presence and absence of parasites. Interestingly, we find that sexual individuals are currently more susceptible to parasites than are asexual individuals. In tanks in which sexual parents are relatively more infected, the frequency of sexual individuals declined significantly more in the offspring generation, indicating a fitness consequence of parasitism for sexual reproduction. Our findings suggest that parasite selection can indeed operate on reproductive mode. Moreover, our results are consistent with theory (King, Delph, Jokela, & Lively, 2009) and a prior field study in our system indicating that the direction of parasite selection is variable, such that parasites periodically select against sexual reproduction (Vergara, Lively, King, & Jokela, 2013). This current experiment will continue for multiple years in order to track the variation in parasite selection on sex through time.
Part Consolidation for Additive Manufacturing Demonstrated in the Design of a 3D-Printed Harmonic Drive
Authors: Cardona Carolina
Published: February 2019

The goal of this project is to establish a novel design approach for the additive manufacturing of mechanical transmission systems. Our focus is the design and 3D printing of a harmonic drive. Harmonic drives use the elastic dynamics of metals to create an elliptical rotation, which is what conceives the reduction of speed of the outer piece. Additive manufacturing is used to achieve more complex and precise mechanical structures. Components of less complexity will be 3D printed with polymer and commercial parts will be purchased. There is a need for the creation of new plastics manufacturing processes that define and simplify the decision methods involved in the production. With this project, we will establish the process we consider best for plastic additive manufacturing. The decision of which parts are 3D printed or machined affects the harmonic drive’s cost and lead-time; therefore, several alternatives are systematically analyzed. The final bill of materials contains the list of commercial parts and 3D printed parts. When assembled, a functioning harmonic drive is produced. The final harmonic drive is experimentally tested to determine the life of its components when subjected to working loads. The methods used in this research include the part consolidation for the optimization of the system, transcription of 3D models to STL files that can be printed, polymer additive manufacturing and traditional quality control techniques to improve the design. Material models utilized in this project are commercial aluminum parts, 3D printer and plastic, and a low-voltage power motor. The complete set of results will give torque and speed reduction ratios that will be compared to those previously obtained by electronic simulations. This locates us a step ahead in the creation of an optimal process for additive manufacturing.
Host Flower Infection of Silene latifolia by Microbotryum violaceum
Authors: Patel Reshma
Published: February 2019

Certain fungi can infect host plants and thereby cause sterility of the host. One such fungal parasite, Microbotryum violaceum (commonly known as anther smut), has host specificity to plants of the family Caryophyllaceae. Anther smut takes over the host reproductive system by inhibiting sex-organ development in flowers, and the plant produces fungal spores in place of its normal reproductive structures. Spores can then be spread to nearby hosts through wind and insect pollinators. This experiment focuses on Silene latifolia plant populations growing near Zagreb, Croatia. Our research tests for phenotypic differences between infected and healthy flowers. To do this, we measured the size of healthy and infected flowers of both sexes. Additionally, we observed the proportion of infected flowers over time on individuals to uncover temporal trends of the smut infection. We found that all flower parts, regardless of plant sex, are significantly smaller in smut-infected flowers. After observing proportions of infected flowers, we found that the ratio of infected to healthy flowers increased over time. Our findings suggest that smut infection of S. latifolia causes changes in plant energy allocation. We propose that the smaller flower size could be the result of increased energy needed for M. violaceum spore production. This hypothesis could be tested with additional research. The increasing proportion of smutty flowers on an infected individual over time is likely caused by the spread of the infection throughout the plant.
Effects of Filament Diameter Tolerances in Fused Filament Fabrication
Authors: Cardona Carolina , Curdes Abigail H , Isaacs Aaron J
Published: February 2019

Fused filament fabrication (FFF) is one of the most popular additive manufacturing (3D printing) technologies due to the growing availability of low-cost desktop 3D printers and the relatively low cost of the thermoplastic filament used in the 3D printing process. Commercial filament suppliers, 3D printer manufacturers, and end-users regard filament diameter tolerance as an important indicator of the 3D printing quality. Irregular filament diameter affects the flow rate during the filament extrusion, which causes poor surface quality, extruder jams, irregular gaps in-between individual extrusions, and/or excessive overlap, which eventually results in failed 3D prints. Despite the important role of the diameter consistency in the FFF process, few studies have addressed the required tolerance level to achieve highest 3D printing quality. The objective of this work is to develop the testing methods to measure the filament tolerance and control the filament fabrication process. A pellet-based extruder is utilized to fabricate acrylonitrile butadiene styrene (ABS) filament using a nozzle of 1.75 mm in diameter. Temperature and extrusion rate are controlled parameters. An optical comparator and an array of digital calipers are used to measure the filament diameter. The results demonstrate that it is possible to achieve high diameter consistency and low tolerances (0.01mm) at low extrusion temperature (180 °C) and low extrusion rate (10 in/min).
A proposed EEG study: the role of object affordance during action observation
Authors: Hailperin-Lausch Rebecca Elisabeth
Published: February 2019

Over the past two decades, research on the human mirror neuron system (MNS) has flourished. According to this model, there is substantial evidence that both action execution and action observation activate the motor system. However, to date, few studies have attempted to examine the role that object affordance may have during action observation. The proposed study attempts to assess this and other issues by having participants watch videos of an actor making goal-directed reaches to a common household object. In the congruent condition, the actor makes a reach and grasps the handle of a mug. In the affordance incongruent condition, the actor makes a reach but grasps the side of the mug opposite from the handle. Electroencephalogram (EEG) will be recorded throughout participant viewing and the EEG data will be decomposed into frequency bands using a Morlet wavelet analysis. The mu rhythm (8-13 Hz) will be of particular interest. Electrode sites of interest include sites over the central parietal areas as well as frontal sites. It is hoped that the proposed study will provide insight into the role of object affordance during action observation.
Food Access in the Age of Online Grocery: An Evaluation of Current Retail Trends and Their Potential to Alleviate Food Deserts in the U.S.
Authors: Meslin Halley Rose
Published: February 2019

Online grocery shopping is growing rapidly and has been heralded as a potential solution to food insecurity. Supermarkets are increasing their online presence, and some have joined the United States Department of Agriculture’s (USDA) pilot program aimed at increasing online grocery access among Supplemental Nutrition Assistance Program (SNAP) participants. Although both the growth of the online grocery industry and the launch of the USDA pilot program are steps in the right direction for greater food access, it is worth asking how these initiatives will address food access among low-income consumers. This paper aims to answer the following questions: does online grocery shopping reduce or eliminate food access barriers for low-income consumers? Does it introduce new barriers? Does online grocery shopping have the potential to reshape the definition of a food desert? Using Hilary Shaw’s (2006) categorization of food access barriers—ability, asset, attitude—as a framework, online grocery shopping motivations were reviewed, and a case study on current practices at Kroger, Wal-Mart, and Amazon Fresh was conducted. The results suggested that none of the retailers’ current practices significantly reduce the barriers that low-income consumers are likely to experience when trying to shop online. Although the online channel eliminates the physical barrier of having to carry groceries, it in turn introduces new barriers, such as sensory risk aversion to buying perishables online, the necessity of possessing relevant technological skills, and having access to a computer. This paper proposes a new term, “digital food desert,” to define (1) a community without access to online grocery due to infrastructure constraints, or (2) a community with access to online grocery, but whose market manifests the conditions of a physical food desert online.
One-for-One Companies: Helpful or Harmful?
Authors: Taylor Grace Alden
Published: February 2019

One-for-one companies, such as TOMS and Warby Parker, have become a common occurrence in the marketplace. These companies promise to donate a good or service for every product purchased. To date, millions of products have been donated worldwide. This paper seeks to analyze the positive and negative impacts of the one-for-one model on both the one-for-one company and the people receiving product donations. A specific focus of the paper is to determine whether the one-for-one model is helpful or harmful to companies and beneficiaries. To gather information, I contacted sixteen one-for-one companies and asked for reports, gathered preliminary research completed by news outlets such as Forbes and the New York Times, and analyzed academic research. The study finds that the one-for-one model can be both helpful and harmful, depending on the conditions in which the giving is done. For example, if there is an immediate need for a good that cannot be produced in the beneficiary country, then a donation would be beneficial. However, if a donation such as shoes ultimately takes away jobs and reduces the market in the beneficiary country, then it causes more harm and long-term damage than it prevents. As this model becomes more common, it is important that consumers know the impact of their purchases on the beneficiaries and the companies know the benefits and repercussions of their actions.
Using the Predicted Structure of the Amot Coiled Coil Homology Domain to Understand Lipid Binding
Authors: Peck Cameron James , Virtanen Piia , Johnson Derrick , Kimble-Hill Ann
Published: February 2019

Angiomotins (Amots) are a family of adapter proteins that modulate cellular polarity, differentiation, proliferation, and migration. Amot family members also have a characteristic lipid-binding domain, the coiled coil homology (ACCH) domain that selectively targets the protein to membranes, which has been directly linked to its regulatory role in the cell. Several spot blot assays were used to validate the regions of the domain that participate in its membrane association, deformation, and vesicle fusion activity, which suggested the need for a structure to define the mechanism. Therefore, we endeavored to understand the structure-function relationship of this domain with the desire to find ways to modulate these signaling pathways. After many failed attempts to crystallize the ACCH domain of each of the Amot family members for structural analysis, we decided to pursue homologous models that could be refined using small angle x-ray scattering data. Theoretical models were produced using the homology software SWISS-MODEL and threading software I-TASSER and LOMETS, followed by comparison to SAXS data for model selection and refinement. As a result, we present a theoretical model of the domain that is driven by alpha helices and short random coil regions. These alpha helical regions form a classic dimer interface followed by two wide spread legs that we predict to be the lipid binding interface.

A Case Study on Experiential Learning in a First-Year General Education Course
Authors: Weller Niki , Saam Julie
Published: February 2019

Experiential-learning provides opportunities for students that feature a variety of high-impact practices including first-year seminars, internships, community learning, collaborative projects, and capstone seminars. To offer these high-impact practices for students, faculty from across disciplines and majors must be willing to incorporate these opportunities within their courses and degrees. Indiana University Kokomo has offered two successful programs to support these high-impact practices. One program, the Kokomo Experience and You (KEY), supports faculty in the development and implementation of events and activities to support student learning. The other, the Student Success Academy Faculty Fellows Program, provided faculty members the opportunity to examine research and concepts so that they can better promote student success in their classrooms. Building on the success of these two programs, a third initiative, the Experiential Learning Academy (ELA), was launched in 2018, funded by a Reimagining the First Years mini-grant from AASCU.

Dolgaya Spit: Tourism on the Azov Seacoast
Authors: VOLKOVA Tatiana Aleksandrovna
Published: February 2019

The Krasnodar region is one of Russia’s four leaders in terms of tourism development. The number of tourists who visit the Krasnodar region has been rising year after year. Specially protected natural areas, which attract a lot of tourists, come under pressure. Nowadays, natural monuments turned into travel destinations, as a rule, of short-term trips (the so-called weekend journeys). The Dolgaya Spit area is an example of extensive use of natural monuments. It can be expected that tourist flow might exceed the current level, maybe by several times, on the back of rising popularity, the development of transport infrastructure and improved beach quality. To date, the failure to resolve the current problems for a long time has led to unfavorable consequences, with the natural monument degrading rapidly amid growing recreational pressure. The situation is quite complicated. On the one hand, the area’s economic prospects as a resort are unquestionable, although, on the other hand, the Dolgaya Spit needs protection because it is now under the influence of constantly rising anthropogenic factors.

The article analyses the competitiveness rural working age population of Russia employed in the agro-industrial complex. The authors conclude that their competitiveness does not answer the challenges posed by current development of Russian agro-industrial complex. This situation is caused by the absence of an integrated strategic governmental approach to the creation of conditions for the rise of the competitiveness of rural population of working age employed in the agro-industrial complex of the Russian Federation, both in a whole and in regional agro-industrial complexes. Authors propose particular measures to increase the efficiency of governmental management of the competitiveness of rural working age population employed in Russian agro-industrial complex: to create conceptual, legal, organizational and strategic conditions that would ensure concentration and goal-directed disposal of resources in this area. Analysis of the results of the sociological survey conducted by the Federal State Statistics Service of the Russian Federation allowed to distinguish threshold indicators of significant social factors of competitiveness: health self-assessment and active lifestyle abilities of the rural working age population employed in Russian agro-industrial complex. Threshold indicators used in the current state programs will help clarify the goals and select priorities for a state competitiveness management policy for rural working age population employed in the agro-industrial complex of the Russian Federation.

Wool suits are always preferred due to their warmth retention in cool weather, comfort, and aesthetic features. Seams are very important for the quality of wool suits. The tensile characteristics of seamed fabric change with the change of fabric bias angle. This study aimed to investigate the effects of different seam angles with various stitch densities on the seam strength and the seam breaking extension of wool suit stitches. In this study, seam strength and seam-breaking elongation at different bias angles were investigated for the stitches of trousers and jackets of wool suits. As is known, in the production of trousers and jackets, the seams are applied not only in the direction of the weft and warp but also in the different bias angles at the crotch area and arm hole seams. Six wool fabrics with different structural properties were chosen as experimental samples. Fabrics were cut at 0°, 30°, 45°, 60°, and 90° angles and then sewn with three different stitch densities (3, 4, and 5 stitches/cm), with lockstitch stitch type for each fabric angle. Therefore, 90 differently seamed fabric samples were prepared. The results indicated that seams prepared with 0°,45° and 90° bias angles give the highest seam strength and that 30°, 45°, and 60° bias angles give the highest seam-breaking elongation values all over the samples. Seams prepared with 30° and 60° bias angles give the lowest seam strength, and 0° and 90° bias angles give the lowest seam-breaking elongation values all over the samples.

Background and objective

Adolescence is a transition period involving tremendous physical, psychological and cognitive growth. For appropriate growth of adolescents in these aspects, a correct quantity and quality of nourishment is required, as a lack of such nourishment among adolescents can lead to various degrees of malnutrition, which may have implications on their health as well as their academic achievements.

Materials and methods

This review examines the research topics around factors that influence the nutritional status of adolescent students which can affect their academic performance.

Results

Some of the vital factors include knowledge and attitude about nutrition, eating behaviour, physical activity, socio-economic status of the family, the surrounding environment at school and home, the frequency and timing of meals, nutritional contents and amount of food intake.

Conclusion

Students who consume a balanced diet perform better in exams, show better behaviour as well as attendance at school and get their assigned tasks done more thoroughly compared with those who do not consume a balanced diet.

Background

When evaluating peripubertal short stature patients, the interpretation of insulin-like growth factor 1 (IGF-1) levels based on chronological age (CA) can be inaccurate due to the influence of sex steroids and, presently, there is no evidence to support the assessment of IGF-1 values according to bone age (BA) and pubertal status (PS). Our objective was to assess the discriminatory performance of IGF-1 levels based on CA, BA and PS in the diagnosis of growth hormone (GH) deficiency.

Methods

We evaluated IGF-1 levels from 154 peripubertal short stature patients classified as GH deficient (GHD, n=23) or non-GHD (n=131). IGF-1 was assayed by a chemiluminescent immunometric assay and transformed into standard deviation scores (SDS) according to CA (IGF-1-SDS-CA), BA (IGF-1-SDS-BA) and PS (IGF-1-SDS-PS).

Results

The performances of IGF-1-SDS-CA, IGF-1-SDS-BA and IGF-1-SDS-PS in the receiver operator characteristics (ROC) curves were similar. There were greater accuracy and specificity of IGF-1-SDS-PS (98.4% and 93.3%, respectively) and IGF-1-SDS-BA (92.7% and 90.1%, respectively) when compared to IGF-1-SDS-CA (65.6% and 69.5%, respectively). The post-test probability of the IGF-1-SDS was also improved when compared to PS and BA – 44.8% (IGF-1-SDS-PS), 16.8% (IGF-1-SDS-BA) and 5.1% (IGF-1-SDS-CA), with similar negative predictive values.

Conclusions

The evaluation of IGF-1 levels based on CA has a higher sensitivity than those based on BA or PS, which justify its use as a screening tool. Additionally, IGF-1 assessed by PS has the best positive predictive power for GHD diagnosis in peripubertal age and could reduce the necessity of a second GH stimulation test.

Background: Health literacy has received growing attention in recent years to reduce health disparities. Health literate individuals can gain access, understand and use health information to maintain, improve and promote good health. Objective: To develop and assess the psychometric properties of a tool for the measurement of health literacy among workers, the Health Literacy Scale for Workers (HELSW). Methods: 15 companies were selected from the factories of the industrial city of Saveh. 450 (400 male and 50 female) workers from Saveh, Iran, were selected through a multistage random sampling. The study had two stages—a qualitative and a quantitative stage. In the qualitative phase, the workers' beliefs were extracted based on 61 in-depth interviews. Content validity was assessed with the help of 12 experts in the field of health education, public health and occupational health. Also, face validity was evaluated through interviewing with 20 workers. In the quantitative phase, the reliability of the questionnaire was evaluated by measuring the internal consistency and test-retest reliability. The construct validity was assessed by the principal component analysis using varimax rotation. Results: In the exploratory factor analysis, six domains (ie, access, reading, understanding, assessment, decision making and applying health information, and self-efficacy) with 34 items were loaded; the model explained 64.3% of the total variance. Intraclass correlation coefficient and test-retest reliability ranged from 0.72 to 0.84 and 0.69 to 0.86, respectively. Conclusion: It seems that the developed Persian questionnaire, HELSW, is a reliable and valid measure of the health literacy in workers.

Authors: González-Sandoval German Eduardo
Published: February 2019

Este ensayo versa sobre la necesidad de implementar los principios de la andragogía en la Universidad Nacional. Por ende, se hace un repaso general por su normativa, la cual respalda la eventual inclusión de la andragogía en el nivel institucional; se presenta un esbozo comparativo sobre sus alcances con los de la pedagogía, sus características generales, sus beneficios para el aprendizaje de los adultos y sus principios básicos. El texto tiene la finalidad de generar una reflexión para desarrollar acciones y lineamientos en los que se enmarque el quehacer académico de la Universidad, tomando en cuenta las características para el aprendizaje de la persona adulta. Se desarrolla un modelo con cuatro elementos básicos por contemplar en todo modelo institucional, a saber: el concepto general del aprendizaje, el papel de la experiencia del aprendiz, disposición para aprender y orientación al aprendizaje. Para ahondar en el análisis, se propone un concepto holístico sobre el ser humano desde las dimensiones biológica, social, psicológica y legal, su conceptualización específica señalando las dimensiones cognitiva, física, emocional y personal. Finalmente, se plantean algunas conclusiones que confirman la necesidad de implementar la andragogía en la enseñanza superior y en el quehacer de la Universidad Nacional, para garantizar el abordaje en los procesos educativos de los estudiantes universitarios que son del grupo etario de personas adultas.
