La medición de la autoestima en adolescentes y adultos: una propuesta desde el modelo de Harris Clemens
Authors: Cerna Dorregaray Orlando
Published: February 2021

Si bien la investigación sobre la medición de la autoestima es amplia y es una variable que se relaciona con otras como pueden ser, la agresividad, el rendimiento académico, el éxito o fracaso escolar; hemos podido constatar que los fundamentos teóricos y los instrumentos utilizados en la mayoría de los estudios son mayormente los mismos. Así tenemos las investigaciones hechas con niños y adolescentes en los últimos diez años, han partido de las propuestas teóricas de Branden, Milicic, Misitu, y utilizando escalas como la de Rosemberg y Coopersmith. Dentro de los estudios que realizamos tuvimos la oportunidad de conocer una propuesta teórica importante y diferente, que ha sido útil en la explicación de la autoestima en niños y su relación por ejemplo con el éxito escolar. Esta es la propuesta de Harris Clemens (1998) sobre la autoestima. Clemens sostiene que la autoestima es la satisfacción que sentimos de nosotros mismos cuando hemos podido satisfacer cuatro necesidades básicas: la vinculación, la singularidad, el poder y las pautas.

La marginal desigualdad: la desigualdad social como fantasía de y para el consumo
Authors: Coriñaupa Vargas Francisco Augusto
Published: February 2021

Cuando se trata de desigualdad social y marginalidad, habitualmente hacemos alusión al chiste irónico arriba colocado, no obstante y aunque suene a chiste, es lo que se persigue en el fondo, en un afán por lograr una igualdad inexistente entre individualidades. En ese sentido cabe cuestionar, en qué medida la llamada desigualdad social o la marginalidad pueden existir, ya que al estar inmersos bajo un imperativo de consumo, bajo el cual nada escapa a la esfera de lo económico y a la idea de “desarrollo” –aunque este también sea un término sospechoso, ya que su definición depende de los tiempos y del lugar en que se vive – que se maneja en esta parte del mundo, se puede afirmar que nada escapa a la impronta capitalista, por lo que se transforma en medida de todas las cosas socialmente aceptadas, incluso consideradas “normales”, si es que acaso se puede hablar de eso.

Cisto odontogênico glandular tratamento cirúrgico por marsupialização e enucleação: relato de caso
Authors: Oliveira Letycia Maria Lopes de , Oliveira Gabriella Mendes , Cardoso Sérgio Vitorino , Rocha Flaviana Soares , Henriques João César Guimarães
Published: February 2021

O cisto odontogênico glandular (COG) é o cisto de desenvolvimento mais agressivo e raro dentre todos os odontogênicos, portando características epiteliais glandulares ou salivares. O presente artigo visa retratar uma abordagem mais conservadora para esta importante lesão, no sentido de minimizar a morbidade decorrente da abordagem mais radical. Paciente com 57 anos, leucoderma, assintomático e edêntulo, compareceu ao ambulatório de estomatologia com notável expansão no fundo de saco vestibular e rebordo inferior direito, com tempo indeterminado de evolução. Os exames imaginológicos revelaram uma lesão radiolúcida unilocular extensa e bem delimitada na região anterior da mandíbula. Nas condutas propedêuticas, foi realizada uma punção aspiratória positiva para líquido cístico seguido de biópsia incisional. Diante destes achados, a marsupialização foi realizada no sentido de se conseguir a redução das dimensões lesionais, seguido da enucleação com estectomia periférica após 9 meses. Nos primeiros 2 anos de proservação o paciente mantém-se sem recidivas e em constante acompanhamento. Conclui-se que o dentista pode preferir o método conservador pela técnica de marsupialização seguida de enucleação na abordagem de extenso cisto odontogênico glandular, desde que haja colaboração do paciente nos cuidados pós-operatórios.

Authors: Gonçalves Ana Cecília Ramos , Aquino Pedro Henrique Fonseca , Torres Silvério Almeida Souza , Mendes Danilo Cangussu
Published: February 2021

Aim: This case report aimed to discuss the clinical sequence and the indications of the direct veneer technique with composite resin to mask a discolored tooth. Case report: A 18-year-old male patient attended a Dental School for treatment of the maxillary central incisors. During the initial examination, the patient reported a dental traumatism in childhood fracturing both teeth. Tooth 21 had already been endodontically treated, and the patient complained of the darkened color, while tooth 11 had been fractured for a long time. Results: Poor class IV composite resin restoration was found, showing rests of endodontic material on tooth 21 and class IV dental fracture on element 11. The elements were cleaned, restorative materials were removed and composite resin veneers were made using a silicone guide technique. Finishing and polishing were performed in the next session, reproducing some of the peculiar characteristics of young teeth, consistent with the patient's age, such as macro and microtextures. Conclusion: The use of direct veneers in composite resin proved to be efficient to restore the aesthetics of darkened and fractured teeth, restoring aesthetic satisfaction through the transformation of the patient's smile.
Blind Hyperspectral and Multispectral Image Fusion Using Coupled Non-Negative Tucker Tensor Decomposition
Authors: Zare Marzieh
Published: February 2021

Fusing a low spatial resolution hyperspectral image (HSI) with a high spatial resolution multispectral image (MSI) to produce a fused high spatio-spectal resolution one, referred to as HSI super-resolution, has recently attracted increasing research interests. In this paper, a new method based on coupled non-negative tensor decomposition (CNTD) is proposed. The proposed method uses tucker tensor factorization for low resolution hyperspectral image (LR-HSI) and high resolution multispectral image (HR-MSI) under the constraint of non-negative tensor ecomposition (NTD). The conventional non-negative matrix factorization (NMF) method essentially loses spatio-spectral joint structure information when stacking a 3D data into a matrix form. On the contrary, in NMF-based methods, the spectral, spatial, or their joint structures must be imposed from outside as a constraint to well pose the NMF problem, The proposed CNTD method blindly brings the advantage of preserving the spatio-spectral joint structure of HSIs. In this paper, the NTD is imposed on the coupled tensor of HIS and MSI straightly. Hence the intrinsic spatio-spectral joint structure of HSI can be losslessly expressed and interdependently exploited. Furthermore, multilinear interactions of different modes of the HSIs can be exactly modeled by means of the core tensor of the Tucker tensor decomposition. The proposed method is completely straight forward and easy to implement. Unlike the other state-of-the-art methods, the complexity of the proposed CNTD method is quite linear with the size of the HSI cube. Compared with the state-of-the-art methods experiments on two well-known datasets, give promising results with lower complexity order.

Limitations of Immunohistochemistry in Diagnosis of a Primary Mucinous Carcinoma of the Skin and Its Metastasis
Authors: C Mann , A Schad , W Mann , B Weidenthaler-Barth
Published: February 2021

We describe the case of a 67-year-old female patient who presented with an unclear swelling on the right supraclavicular neck, two years after resection of a mucinous carcinoma on the right mastoid. Two pathological reports from separate universities diagnosed the primary mastoid skin lesion as a metastatic adenocarcinoma. Strikingly, GATA binding protein 3 (GATA3) and mammaglobin, both immunomarkers found in breast cancer, were positive. An urgent search for the primary tumor most likely in the breast was commenced. However, as no other primary tumor could be detected at that time, a Primary Mucinous Carcinoma of the Skin (PMCS) was also debated.

Two years later neck node enlargement was suspicious for lymph node metastasis during ultrasound examination and conservative neck dissection was performed. Immunohistochemistry revealed again GATA 3, Mammaglobin, estrogen, and progesterone receptor positive tissue. Using a variety of other markers, we were unable to detect neither significant morphological nor immunohistochemical characteristics that distinguished the lesion from a mucinous carcinoma of mammary origin. Following a detailed review of the clinical context, we concluded the lesion to be consistent with a late metastasis of a PMCS. This report demonstrates the limitations of currently used histopathological and immunohistochemical differentiation in metastatic mucinous carcinoma.

Published: February 2021

The results of effect of deposition temperature and the overlap coefficient on the formation of the phase composition of coating based on Cu, Zn and Al2O3 particles mixture applied by cold gas-dynamic deposition are presented. Using X-ray diffraction and X-ray spectral analysis, it is shown that when using the 55 % overlap coefficient
electron-type compound based on CuZn3 (ε-phase) is formed in the coating, the mass fraction of which increases
to 11.4 % with increase in the deposition temperature. Deposition with 64 % overlap coefficient is accompanied
by the formation not only of the ε-phase, but of electron-type compound based on Cu5Zn8 (γ-phase), the mass
fraction of which increases to 33 % at temperature of 450 °C. In the process of coating deposition, the predominant diffusion copper into zinc takes place; the calculations show high value of the diffusion coefficient copper —
1,56•10–13 m2 /s.

Characterization of Reclaimed Asphalt Pavement and Optimization in Polymer Modified Asphalt Blends: A Review
Authors: Michael Tiza
Published: February 2021

This study reviews relevant literature on the characterization of reclaimed asphalt pavement (RAP) and its interaction with polymer modified asphalt(PMA). The study on fatigue cracking indicates that several indexes of binder performance usually decreased the tolerance to cracking of the Polymer Modified Asphalt (PMA). In another perspective, RAP binding rigidity affects the PMA binder tolerance to fatigue. The greater the rigidity of the RAP binder, the more fatigue strength the binders would provide. In addition, several researchers have demonstrated that the quality of RAP binder decreased the elastomeric response worth. It was generally found that the RAP binder effect on the PMA binder is similar to the unmodified binder effect. The resistance to rutting in the PMA binder improves and at the same time, fatigue cracking and thermal cracking are adequately minimized. Moreover, several researchers have shown that the inclusion of a RAP lowers elastomeric efficiency. In summary, RAP binding stiffness and gradation are essential features for PMA-mix designs. The review further illustrates that during the process of RAP binder characterization, the mortar testing process without the use of binder extraction is more effective than the conventional method. Also, the best measure for the evaluation of the fatigue cracking efficiency of RAP containing PMA blends does not seem to have gained any consensus among researchers as several researchers seem to have varying conclusions. Literature on Life Cycle Analysis of RAP has also been reviewed and presented.

Effect of Adding Different Levels of Portulaca oleracea L. Seeds and Leaves Powder to The Diet on Productive and Physiological Performance of Broiler Chickens (Ross 308)
Authors: Shirshaab Ahmed J. , Jassim Jaffar M.
Published: February 2021

This study was conducted in the Poultry Field of the College of Agriculture, Basrah University for the period from 20/9/2019 to 24/10/2019 to investigate the effect of adding different levels of Portulaca oleracea L. seeds and leaves powder on some physiological characteristics of broilers. A total 216 one day old unsexed Ross-308 broiler chicks were used in this study. The chicks were randomly distributed into six treatments replicated three times (12 chicks each replicate). The experiment was designed as a completely randomized design (CRD). The first treatment was control (basal diet), P. oleracea seed powder was added as 5 & 10 g.kg-1 for the 2nd and 3rd treatments. Leaves powder was added as 5 and 10 g.kg-1 to the basal diet in treatment 4th and 5th. In the 6th treatment 5 gm of seed and 5 gm of leaves powder was added to the basal diet. The results showed that there was a significant (P <0.05) decrease in serum glucose, cholesterol and triglyceride concentrations in all additive treatments compared to control. There was also a significant decrease (P <0.05) in Escherichia coli bacteria count, as well as a significant improvement (P <0.05) in the number of Lactobacilli bacteria in all addition treatments compared to the control group. The addition of P. oleracea seeds and leaves powder had no significant effect on some haematological indices and on the total protein concentration in the serum. The study confirms the importance of adding powder of seeds or leaves in the broiler diet because it has a positive role in improving some of the physiological and microbial blood characteristics of the broiler.
La relevancia de la doctrina de las vulneraciones indirectas de los derechos fundamentales. ¿Es asumible una pluralidad de contenidos de la dignidad humana?
Authors: De la Quadra-Salcedo Janini Tomás , Rodríguez Fernández Ignacio
Published: February 2021

En la doctrina del Tribunal Constitucional, la categoría de la “vulneración indirecta” de los derechos fundamentales ha sido utilizada para impedir el reconocimiento u homologación de resoluciones extranjeras que, por resultar contrarias a estándares generales de interpretación de los derechos humanos, comprometen la idea misma de dignidad humana. Al hilo de tal doctrina, la reciente STC 132/2020, de 23 de septiembre, parece sugerir que ciertas exigencias del derecho de defensa, supuestamente inherentes a la idea de dignidad humana, pueden ser ignoradas dentro del espacio de cooperación judicial de la Unión Europea pero no en la cooperación con terceros estados, para los que regiría un estándar diferente de dignidad. A nuestro juicio, esta es una interpretación que desfigura la categoría de las vulneraciones indirectas y que puede tener derivas preocupantes en el futuro, como la relativización del papel de los derechos humanos en la conformación de la identidad europea, el favorecimiento de una política judicial de tutelaje constitucional de terceros estados y la alteración de las reglas que hasta ahora han regido las relaciones del Tribunal Constitucional español con el ordenamiento jurídico de la Unión.

Published: February 2021

This Article addresses developments in Virginia oil and gas law for the period from July 31, 2014 to July 31, 2019. This period is longer than normally addressed by this journal to capture important developments in the law between this update and the last Virginia update published in 2015. At the state level, in Swords Creek Land Partnership v. Belcher, the Supreme Court of Virginia concluded coalbed methane (“CBM”) is a separate and distinct mineral estate from coal. It held that the meaning of “coal” within an 1887 severance deed was unambiguous and did not intend to convey ownership rights to the CBM.1 This decision reaffirmed and expanded the Court’s previous holding in Harrison-Wyatt. In Dye v. CNX Gas Co., the Court held that a deed conveying “all coal and minerals” was also unambiguous and with the addition of the “and minerals” language constituted a transfer of CBM.

A Comparative Analysis of Texas and New Mexico Oil and Gas Laws from a Title Examiner's Perspective
Authors: Hewett Carly
Published: February 2021

The statutory framework surrounding oil and gas law and the related title issues in Texas and New Mexico, while similar in many instances, do have some notable differences. New Mexico case law is very limited, which could be due to a variety of reasons, including a smaller state population and the fact that New Mexico and the United States own much of New Mexico’s oil and gas productive acreage. Therefore, practitioners often look to other jurisdictions, including Texas, for guidance. Texas’s secondary authority is also better developed with its own adopted title standards. New Mexico does not have such guidance. This Article will focus on the distinctions between the oil and gas laws and the passage of title in Texas and New Mexico from a title examiner’s perspective. Both states do have a regulatory body—the Texas the Railroad Commission (“TXRRC”) and the New Mexico Oil Conservation Division (“NMOCD”)—that oversees oil, gas, and other mineral activities by regulating activities such as well spacing, allowables, and pooling.
Louisiana
Authors: Hall Keith B.
Published: February 2021

In Guilbeau v. BEPCO, L.P., a landowner filed suit seeking remediation of contamination arising from oil and gas activities prior to his purchase of the property. The landowner previously had filed a suit seeking a clean-up based on the defendants’ obligations under the Louisiana Mineral Code. That earlier suit was dismissed based on the subsequent purchaser doctrine. The subsequent purchaser doctrine states that private claims for damages to property belong to the person who owned the property at the time of the damages and absent that person’s assignment of his claims to a subsequent purchaser of the property, the subsequent purchaser does not have a claim against the person who caused the damages. In the current suit, the landowner seeks injunctive relief—in particular, an order requiring a remediation—in a citizen suit brought pursuant to Louisiana Revised Statutes 30:14 and 30:16.

Zapadni Balkan suočava se s dvostrukim izazovom internetskog ekstremizma. Internetske platforme omogućavaju specifično ciljanje regiona različitim međunarodnim ekstremističkim narativima. U međuvremenu se regionalne historije i geopolitika prisvajaju kako bi se opravdale ekstremističke aktivnosti i narativi širom svijeta. Međutim, taj fenomen je dio šireg trenda koji naglašava sve veći izazov koji predstavlja širenje transnacionalnih ekstremističkih ideologija na internetskim platformama, kako među nasilnim džihadistima tako i među ekstremnim desničarima. Na Zapadnom Balkanu to predstavlja niz specifičnih rizika.

Adenoid cystic carcinoma is a rare malignant neoplasm of the salivary gland. Salivary gland neoplasms constitute 3% of cancers of all sites, of which, 10–15% are malignant. Though adenoid cystic carcinoma is the most common malignant tumor of the submandibular, sublingual and minor salivary glands, it accounts for only 15% of parotid cancers. They are generally slow-growing and spread relentlessly to adjacent structures. Hematogenous spread is more common than lymphatic spread, the common sites of metastasis being the lung, bone, liver, and brain. We present a case of multiple liver metastases occurring 3 years after surgery for adenoid cystic carcinoma of the parotid gland.

The primary therapy, metastasis, and outcome of adenoid cystic carcinoma are discussed.

The tiger nut contains different active ingredients like oil, tannins, sterols, saponins, alkaloids, vitamins C and E, minerals, and resins. There is a lack of information about carbohydrates content ofCyperus esculentusL. Thus, the aim of this study was to determine the content of carbohydrates of tiger nut herb and tubers. The qualitative composition and quantitative content of carbohydrates in tubers and herb of tiger nut (Cyperus esculentusL.) were determined by using a GC/MS method. The results of analysis showed that tiger nut herb have free carbohydrates, namely D-saccharose, D-glucose, D-Mannitol, and D-fructose, while tubers have only disaccharide D-saccharose. Free D-saccharose presented in raw materials in the greatest amount, the content in tubers was 63.72 mg/g, in the herb – 9.79 mg/g, respectively. Monosaccharides and their derivatives after hydrolysis presented to D-glucose, D-xylose, D-galactose, D-arabinose in tubers, and D-xylose, D-glucose, D-arabinose, D-galactose, D-Dulcitol, D-Mannitol, D-mannose in the herb of tiger nut. D-glucose dominates in tubers and D-xylose in the herb, their content was 177.26 mg/g and 39.07 mg/g, respectively. The total content of fructans was determined by the spectrophotometric method. Its content was 13.49% in tubers and 8.78% in the herb of tiger nut.
Rosemary oil nano-emulsion potentiates the apoptotic effect of mitomycin C on cancer cells in vitro
Authors: Al-otaibi Waad
Published: February 2021

Purpose: To formulate nano-emulsified rosemary oil (REO/NE) and determine its effect on the anticancer agent, mitomycin C (MC) when used as a carrier for the drug.

Methods: The droplet size of REO/NE was markedly enlarged when mixed with MC. The cytotoxicity of the formulations on HeLa and MCF-7 cells was determined using MTT assay. The combination index (CI) values were estimated with CompuSyn software, while apoptosis was determined using DAPI fluorescent dye.

Results: Treatment of MCF-7 cells and HeLa cells with REO/NE (1% v:v and 1.33% v:v, respectively) reduced the IC50 of MC 33 and 15 folds, respectively. Under fluorescent microscopy, cells treated with REO/NE+MC had more marked reduction of the nuclear area than MC-treated cells.

Conclusion: These results indicate that REO/NE is an efficient carrier for MC since it enhanced MC delivery and increased its effect on the cells through the induction of apoptosis at low concentrations of MC.

According to the International Classification of Diseases, osteochondrosis is included in the group of diseases of the musculoskeletal system, mainly the spine. The mechanism of the disease is expressed in the disturbance of blood circulation, which nourishes the bone, and hence the damage to bone and cartilage tissue.

Objective: This paper aims to present the effect of applied pharmacological and active treatment in 10 patients diagnosed with lumbar osteochondrosis.

Methods: We conducted a comprehensive treatment of 10 patients diagnosed with lumbar osteochondrosis without any neurological symptoms during the period 2017–2020. This pharmacological and active treatment lasted from 15 to 17 days. The intensity of the pain symptoms, the general mobility of the spine, and the mobility of the lumbar spine were measured to determine the deficit of the patients. The strength of the flexor and extensor muscles of the body was tested.

Results: A decrease in pain intensity, increase in the strength of the abdominal and back muscles and improvement of the mobility of the back muscles were found in all patients after the complex treatment. As a result of the therapy, a reduction in the patient’s dysfunctions and the risk of developing disabilities was found.

Conclusion: The application of a multidisciplinary approach in patients with osteochondrosis is of great importance for reducing pain intensity and achieving a good functional recovery of motor and stabilizing function of the muscles of the spine.

Background/Aims: Despite controversy regarding the benefits of immunosuppressive therapy in immunoglobulin A nephropathy (IgAN), clinical outcomes may vary depending on the patient’s responsiveness to this therapy. This study evaluated long-term kidney outcomes according to the extent of proteinuria reduction after immunosuppression in IgAN patients.Methods: Among 927 patients with biopsy-proven IgAN, 127 patients underwent immunosuppression. Time-averaged urine protein-creatinine ratio before and within 1 year after start of immunosuppression were calculated, and responsiveness to immunosuppression was assessed as the reduction of proteinuria between the two periods. Patients were classified into tertiles according to the extent of proteinuria reduction. We compared the slopes of estimated glomerular filtration rate (eGFR) decline using a linear mixed model, and estimated hazard ratios (HRs) for disease progression (defined as development of a ≥ 30% decline in eGFR or end-stage renal disease) using a Cox proportional hazard model.Results: Median extent of proteinuria reduction was –2.1, –0.9, and –0.2 g/gCr in the first, second, and third tertiles, respectively. There were concomitant changes in the slopes of annual eGFR decline: –2.03, –2.44, and –4.62 mL/min/1.73 m2 among the first, second, and third tertiles, respectively. In multivariable Cox analysis, the HRs (95% confidence intervals) for disease progression were 0.30 (0.12 to 0.74) in the first tertile and 0.70 (0.34 to 1.45) in the second tertile compared with the thirdtertile.Conclusions: This study showed that greater proteinuria reduction after immunosuppression was associated with a lower risk of disease progression in patients with IgAN, suggesting that responsiveness to immunosuppression may be an important determinant of kidney outcomes.

Global wellposedness of vacuum free boundary problem of isentropic compressible magnetohydrodynamic equations with axisymmetry
Authors: Li Kunquan , Ou Yaobin
Published: February 2021

In this paper, we prove the global existence of the strong solutions to the vacuum free boundary problem of isentropic compressible magnetohydrodynamic equations with small initial data and axial symmetry, where the solutions are independent of the axial variable and the angular variable. The solutions capture the precise physical behavior that the sound speed is \begin{document}$ C^{1/2} $\end{document}-Hölder continuous across the vacuum boundary provided that the adiabatic exponent \begin{document}$ \gamma\in(1, 2) $\end{document}. The main difficulties of this problem lie in the singularity at the symmetry axis, the degeneracy of the system near the free boundary and the strong coupling of the magnetic field and the velocity. We overcome the obstacles by constructing some new weighted nonlinear functionals (involving both lower-order and higher-order derivatives) and establishing the uniform-in-time weighted energy estimates of solutions by delicate analysis, in which the balance of pressure and self-gravitation, and the dissipation of velocity are crucial.
Solving nonlinear differential equations using hybrid method between Lyapunov's artificial small parameter and continuous particle swarm optimization
Authors: Qasim Omar Saber , Entesar Ahmed , Al-Hayani Waleed
Published: February 2021

In this paper, Lyapunov's artificial small parameter method (LASPM) with continuous particle swarm optimization (CPSO) is presented and used for solving nonlinear differential equations. The proposed method, LASPM-CPSO, is based on estimating the \begin{document}$ \varepsilon $\end{document} parameter in LASPM through a PSO algorithm and based on a proposed objective function. Three different examples are used to evaluate the proposed method LASPM-CPSO, and compare it with the classical method LASPM through different intervals of the domain. The results from the maximum absolute error (MAE) and mean squared error (MSE) obtained through the given examples show the reliability and efficiency of the proposed LASPM-CPSO method, compared to the classical method LASPM.

Monte Sinai is a town located in the northwest of the city of Guayaquil, Ecuador, and has about 99,325 hectares. There are some signs that this population is in the process of being transformed into a satellite city, given the increasing number of startups and the formation of small markets to buy and sell raw materials. Also, extreme poverty has increased from 7.9% to 15% from 2010 to 2020. There are approximately 12,152 businesses: cyber shops (spaces for renting internet services by the hour or fraction thereof), grocery stores, canteens, pharmacies, bazaars, hairdressers, chicken restaurants, creative entertainment services, among others. This fact implies an economically active population of 34,584 (there are no rigorous statistics on the population), which means a possibility of a very varied supply at the retail level. The objective of this chapter is to propose a Chamber of Popular Entrepreneurs that will lead to the continuous creation of popular brands. For this goal, the authors analyze the Multiplazas Itinerant Fairs as a strategy for popular micro businesses.
Social Entrepreneurship
Authors: Bernal Jairo Alberto Vasquez
Published: February 2021

This chapter presents the fundamental elements related to the success factors of social organizations. The first step was bibliographic research on social entrepreneurship. This research established that social entrepreneurship improves the quality of life of vulnerable communities, which stands out for the social construction of products, services, and processes that allow social inclusion. Social entrepreneurship in Colombian companies has become a topic of analysis; however, it is still a developing area. The second step was to conduct a quantitative and descriptive investigation in the Colombian coffee region, specifically in the departments of Caldas, Risaralda, and Quindío. The sample distribution of the proportions determined the sample. The information was collected from non-profit companies. The results showed that the success factors are to offer quality services, to have committed human talent, and the adequate management of resources that the competitive advantage is the social need they satisfy, and the social benefit is the reduction of poverty.
