La cultura Zoque de Copoya, Tuxtla Gutiérrez, Chiapas: cosmovisión, ritos y costumbres
Authors:   Universidad Autónoma de Chiapas, Alonzo García Jairo Naaman
Published: June 2021

Una de las problemáticas actuales a los que se enfrenta el contexto social chiapaneco, es el desarraigo de las pertenencias culturales, con esto, lleva a lo que se conoce como: pérdida de identidad cultural. La propuesta teórica, en primer lugar, que se hace en esta investigación, es intenta esbozar de manera general la situación del espacio social de Copoya, de Tuxtla Gutiérrez, Chiapas y a su población originaria zoque. En Copoya, es donde aún se conserva y se arraigan las tradiciones zoques en su totalidad, tanto en comidas, vestuario, festividades, cosmovisiones, etc. La cultura zoque, es la población originaria de Tuxtla Gutiérrez, Chiapas, así como de otros estados vecinos como: Oaxaca y Tabasco, y otros estados. La cultura zoque, es una de las etnias que representa e identifica a los pobladores de la ciudad de Tuxtla Gutiérrez. En la época contemporánea actual, las dinámicas de la globalización han desintegrado ese arraigo cultural con nuevas prácticas sociales impropias del contexto social de Tuxtla Gutiérrez, particularmente de Copoya. Las generaciones jóvenes son el blanco fácil y son los que sufren los efectos de la globalización, construyendo un tipo de ideología y cultura diferente a la propia. Uno de los objetivos de este trabajo es hacer la propuesta de estudio de los zoques de Copoya para resaltar la riqueza inmaterial que es, por otro lado, poner en tela de juicio el desarraigo cultural que va imperando en los distintas contextos sociales de México y el mundo.
Espacios de poder, vacíos educativos: filosofía del poder inteligente
Authors:   Universidad Autónoma de Chiapas, Madrigal Frías Luis , Hernández Reyes Nancy Leticia
Published: June 2021

El poder es una realidad compleja que está implícita en la vida humana y desde lo político, impregna toda la existencia; en la historia ha habido diversas explicaciones teóricas del poder. En este ensayo, el poder ejercido por cuatro Secretarios de Educación del Estado de Chiapas, de 2013 a 2018, se analiza desde la teoría del poder inteligente, cuya filosofía política es la aplicación de la fuerza militar, la seducción y el convencimiento a través de la atracción cultural o apoyo económico. El ensayo inicia con la síntesis del poder inteligente en el ámbito político y en las implicaciones del mercado del consumo impuesto por la globalización; luego, aparece el devenir de los Secretarios de Educación: Mtro. Ricardo Aguilar Gordillo, Profesora Sonia Rincón Chanona, Ing. Roberto Domínguez Castellanos y Mtro. Eduardo Campos Martínez. Los protagonistas de la interacción política serán los estudiantes normalistas, organizados en la Coordinadora de Estudiantes Normalistas del Estada de Chiapas (CENECH) y los profesores de la Coordinadora Nacional de Trabajadores de la Educación (CNTE). En las acciones específicas de los distintos actores mencionados, se descubren las diversas maneras de ejercer el poder: duro, suave, disciplinario y muchas de las veces, el poder inteligente; cada una de estas formas de poder posee sus determinadas circunstancias políticas; de la misma manera, se llega a la conciencia que las tesis discutidas por los filósofos modernistas de la filosofía política ya no poseen mucha fuerza en los actores de la política y desde luego, de la política educativa. Tal vez, en el mundo actual las preocupaciones sean el hábitat, el alimento y el trabajo. La filosofía neoliberal empapa y enajena todos los ámbitos de la conciencia en las esferas del poder y del mercado. Es una filosofía que deja el hombre desnudo de su ser.
De los caminos para la enseñanza de la lógica. Las condiciones de invisibilidad de la lógica desde la academia.
Authors:   Universidad Autónoma de Chiapas, Ruiz Rincón Diana Lizbeth
Published: June 2021

Las condiciones de invisibilidad que suelen tener los contenidos filosóficos tanto en el Nivel Medio Superior como en el Nivel Superior hacen a veces ardua la labor del profesional de la filosofía en relación a su práctica docente. En este sentido, la lógica no se exime de las privaciones de relevancia como herramienta del conocer. Derivado de lo anterior, la novel Línea de Generación y Aplicación del Conocimiento “Epistemología, Lógica y Filosofía Aplicada” de la Facultad de Humanidades de la Universidad Autónoma de Chiapas, integrada por docentes de la Licenciatura en Filosofía ha generado un par de proyectos durante el 2017 denominados: Fortalecimiento de la enseñanza de la lógica en la Licenciatura en Filosofía y, Desarrollo de Materiales Didácticos para la Enseñanza de la Lógica en la Licenciatura en Filosofía, respectivamente. La generación de los proyectos se da en condiciones de no accesibilidad a gestiones de financiamiento, cuyos productos buscan promover tanto la formación en lógica como su divulgación. Los andares y rutas para el fortalecimiento de una de las principales herramientas del filósofo, del profesional de la filosofía y del ser humano en general, donde el discernimiento de argumentos correctos o falaces, su análisis y los métodos para la demostración de la validez, juegan un papel fundamental en la configuración de expresiones del pensamiento.

La utopía de la transdisciplina. Una reflexión crítica desde la noción de dispositivo de M. Foucault
Authors:   Universidad Autónoma de Chiapas, Ruiz Rincón Diana Lizbeth
Published: June 2021

Los modos en los que un dispositivo tiende a desplegarse deja de manifiesto dos formas, a manera de linealidades no uniformes o paralelas, aspectos de visibilidad e invisibilidad, esto es: elementos que en la urdimbre de los procesos de formatividad en campos del conocimiento científico que apelan a los principios epistemológicos, teóricos y metodológicos emanados desde el posicionamiento de lo transdisciplinar, pueden nombrarse y otros cuya categorización demanda el ejercicio analítico/investigativo. La noción de dispositivo que se recupera de los planteamientos teóricos de Michael Foucault, permiten trasladar un análisis crítico-reflexivo sobre la ciencia o bien sobre el fenómeno científico respecto a la polución de la información y la generación de conocimiento, en relación a la diseminación de las fronteras disciplinares como uno de los pilares que el ejercicio surgido desde la filosofía de la ciencia debe procurar en la época contemporánea. Así, la metainvestigación de noveles campos de estudio, como el de los Estudios Regionales, cuya apelación epistemológica apunta a una utopía de la transdiciplina, habrá de permitir visibilizar de manera crítica los alcances, riesgos y compromisos que los procesos de formatividad en un campo en construcción tenderán a la generación de conocimiento difuso. En este sentido, la presente ponencia busca mostrar algunos elementos críticos y de análisis frente a la aventura del “pensar la edificación del conocimiento desde la transdiciplinariedad”; partiendo inicialmente de la explicitación del concepto de dispositivo, para continuar con la presentación de elementos visibles y no visibles cuyas relaciones intrincadas en los procesos de formatividad habrán de concentrarse en la noción de comunidades epistémicas desde las cuales la transdiciplinariedad habrá de buscar su legitimación y legitimidad.
La paradoja de la imposibilidad del conocimiento en el Menón
Authors:   Universidad de Guadalajara, Ramírez González Carlos Fernando
Published: June 2021

La paradoja que aparecen en el diálogo del Menón inaugura un periodo de reflexión en la filosofía platónica. El análisis argumentativo permite ver cómo está conectados estos elementos nuevos: por un lado, se abandona el elenco como la forma prominente para hacer filosofía, junto con ello aparece una propuesta epistemológica que será determinante en el pensamiento de Platón y que en el diálogo (Menón) permite superar el “argumento erístico” con que Menón intenta suspender la disputa. Los argumentos de este pasaje han sido analizados por muchos autores, lo novedoso de mi propuesta es que se hace desde una teoría que considera que la argumentación no es sólo la suma de los argumentos, sino que considera que existen elementos que van más allá de las premisas y la conclusión, que son determinantes en la resolución del diálogo.

Accounting for Imaginary Presence
Authors: Huang Di
Published: June 2021

Both Husserl and Sartre speak of quasi-presence in their descriptions of the lived experience of imagination, and for both philosophers, accounting for quasi-presence means developing an account of the hyle proper to imagination. Guided by the perspective of fulfillment, Husserl’s theory of imaginary quasi-presence goes through three stages. Having experimented first with a depiction-model and then a perception-model, Husserl’s mature theory appeals to his innovative conception of inner consciousness. This elegant account nevertheless fails to do justice to the facticity and bodily involvement of our imaginary experience. Sartre’s theory of analogon, based on his conception of imaginary quasi-presence as ‘magical’ self-affection, embodies important insights on these issues. Kinesthetic sensations and feelings are the modes in which we make use of own body to possess and be possessed by the imaginary object, thus lending it a semblance of bodily presence.
Corporate Social Responsibility Disclosure: From the Perspective of Firm's Characteristics
Authors: Hayat Maqsood , Khan Shehzad , Malik Muhammad Faizan
Published: June 2021

The study analyzed the combined impact of the firm's characteristics on the level of corporate social responsibility disclosure (CSRD). Data were obtained from the annual reports, and all the available assumptions were fulfilled before running the regression models. The results show that the percentage of shares held by the foreigner shareholders, top management, number of total shareholders, and the presence of independent director has a positive relationship with the level of CSRD. In addition, the percentage of the local shareholders has shown a negative association with the level of CSRD. Nevertheless, the firm's profitability shows no significant result, negating the general perception that profitable firms involve in more corporate social responsibility (CSR) activities. Findings offer a comprehensive picture for policymakers, practitioners, and general corporate beneficiaries. This study insight that the involvement in CSR activities is sensitive to the internal corporate structure and the firm's capabilities

Published: June 2021

This study examines the trends of corporate social responsibility (CSR) dynamics within multinational enterprises (MNEs) operating in China. Secondary data was gathered from the published reports (e.g., annual, CSR, sustainability etc.) to measure the study variable with the help of global reporting initiative (GRI-G4) and compute a comprehensive CSR' outline. This study institutes the fundamental but general drifts about the concept of CSR within MNEs in China. Overall, it was found that the inclination of CSR activities is towards social; followed by environmental and economic dimensions. While comparing CSR performance among various sectors, it was reflected that exploration & production, manufacturing and consumer products sectors have outperformed. Similarly, on average, Chinese MNEs disclosed proportionately more CSR activities than Non-Chinese MNEs. These results are very significant both for researchers and corporate practitioners. This research has not only examined the CSR's indicators quantitatively but also its reporting quality, in a quantitative and qualitative manner.
STUDI PENGARUH PENAMBAHAN TANAH LEMPUNG TERHADAP DAYA DUKUNG PASIR PANTAI
Authors: Herman Herman , W Fiska
Published: June 2021

Pasir pantai keberadaannya sangat berlimpah diwilayah Indonesia, hal itu dikarenakan Indonesia terdiri dari pulau-pulau dengan daerah pantai yang sangat luas. Terbentuk akibat pengikisan batuan dari erosi gelombang laut, memiliki tekstur yang halus dan relatif bulat dengan ukuran butir berkisar antara 0,55 – 2,50 mm. Kelemahan tanah pasir ini antara lain, memiliki gradasi butiran seragam, kekuatan geser yang rendah, memiliki daya lekat yang cenderung lemah dan sulit untuk dipadatkan dan mempertahankan kepadatannya karena gampang terhambur akibat beban terutama beban bergerak. Untuk memperbaiki kelemahan-kelemahan tanah pasir pantai tersebut, digunakan tanah lempung. Pasir pantai sebagai sampel diambil dari Pasir Jambak Tabing Padang, tanah lempung sebagai bahan pencampur adalah tanah lempung dari Palapa Batang Anai Pariaman. Komposisi campuran lempung terhadap pasir pantai adalah 0%, 15%, 30% dan 45% terhadap berat kering pasir pantai. Pengujian yang dilakukan terdiri dari uji sifat fisis meliputi uji specific gravity (Gs), batas cair (LL), uji saringan dan hidrometer, sedangkan uji sifat mekanis yang terdiri dari uji pemadatan dan uji CBR laboratorium (soaked, unsoaked). Hasil pengujian menunjukan semakin tinggi persentase tanah lempung didalam kandungan pasir nilai batas cair (LL), persentase lolos saringan no. 200, kadar air optimum, persen pengembangan meningkat, sedangkan nilai-nilai kepadatan tanah, CBR laboratorium (soaked, unsoaked) pada awalnya terjadi peningkatan, seiring dengan bertambahnya jumlah kandungan tanah lempung didalam pasir pantai, nilai-nilai ini cenderung menurun. Hasil terbaik diperoleh dari penelitian ini pada persentase 30% tanah lempung didalam kandungan pasir pantai.
ANALISIS RESPON DINAMIK TANAH BERPOTENSI LIKUIFAKSI PADA UNDERPASS YOGYAKARTA INTERNATIONAL AIRPORT (YIA)
Authors: Rahman Muhamad Agung , Fathani Teuku Faisal , Rifa'i Ahmad
Published: June 2021

Underpass Yogyakarta International Airport (YIA) terletak di pesisir pantai selatan jawa dekat dengan pertemuan lempeng tektonik. Kondisi geologi di lokasi Underpass YIA termasuk formasi geologi endapan alluvial, dimana sepanjang underpass ditemukan lapisan tanah berupa lempung pasiran dan pasir. Aktivitas seismik serta kondisi geologi dan geoteknik menyebabkan wilayah Underpass YIA rentan terhadap gempa bumi berpotensi likuifaksi. Penelitian ini bertujuan untuk menganalisis respon dinamik tiap lapisan tanah berpotensi likuifaksi dengan ragam spektrum Multi Degree of Freedom serta memodelkan lapisan tanah berupa shear building. Evaluasi bawah permukaan didasarkan pada data pengeboran dan N-SPT serta data tanah pada 5 titik di sepanjang Underpass YIA. Nilai percepatan batuan dasar ditentukan berdasarkan peta gempa SNI 1726-2012. Piranti lunak MATLAB digunakan sebagai alat bantu dalam perhitungan analisis perilaku dinamik. Hasil analisis menunjukkan bahwa nilai simpangan tiap lapisan tanah semakin mendekati permukaan cenderung semakin besar karena nilai kekakuan tanah semakin mengecil. Kekakuan tanah yang semakin kecil menghasilkan nilai frekuensi sudut semakin kecil dan periode getar semakin besar mendekati permukaan tanah. Hasil analisis menunjukkan adanya potensi likuifaksi pada kedalaman 4-6 m dari permukaan tanah jika terjadi gempa bumi dengan nilai percepatan muka tanah maksimum (amax) lebih besar dari 0,44g.

Fascial treatment versus manual therapy (HVLA) in patients with chronic neck pain: A randomized controlled trial
Authors: Brück Katrin , Jacobi Kirsten , Schmidt Tobias
Published: June 2021

BACKGROUND: Chronic neck pain (CNP) is a common health problem in western industrialized nations. In recent years, the fascial tissue has attracted the attention of therapists, and a treatment of the fasciae promises to be a meaningful approach in the therapy of patients with CNP. OBJECTIVE: The aim of this study was to investigate the effectiveness of a fascial treatment (FT) compared to manual therapy (MT) and to no intervention (control group, CG) in patients with CNP. METHODS: Sixty participants with CNP were randomized into three groups. Primary outcome parameters were pain intensity as measured by the visual analogue scale (VAS), and severity of illness as measured by the Neck Pain and Disability Scale (NPAD). Secondary outcome parameter was the range of motion (ROM) of the cervical spine. RESULTS: Repeated measures t-tests demonstrated significant decreases with medium to large effect sizes for the FT (VAS: dR⁢M= 1.14; NPAD: dR⁢M= 0.51) and for the MT (VAS: dR⁢M= 1.15; NPAD: dR⁢M= 0.72). CONCLUSION: Our results confirmed the effectiveness of MT on pain and severity of illness in the treatment of patients suffering from CNP. Furthermore, the results demonstrated the effectiveness and clinical relevance of FT for this population.

Authors: Ijiri Tomohito , Urabe Yukio , Maeda Noriaki , Sasadai Junpei , Suzuki Toshiaki
Published: June 2021

BACKGROUND: The role of the serratus anterior is to maintain scapular stability. To strengthen this muscle, scapular protraction exercises are typically performed. Although the angle of arm rotation leads to changes in shoulder muscle activation, the arm rotation position is not normally determined. OBJECTIVE: To investigate if scapular muscle activations were changed by combining arm external rotation during scapular protraction exercises. METHODS: Thirty-four healthy men were enrolled in this study. Participants were instructed to perform scapular protraction exercises at 90∘ and 120∘ of shoulder flexion while in the standing and supine positions. Two different arm rotation angles were used: the thumb-up position (neutral position) and the maximum arm external rotation (ER) position. The percentages of maximum voluntary contractions (%MVCs) were measured, and %MVCs in the neutral and arm ER positions were compared. RESULTS: Muscle activities of the middle serratus anterior (MSA) and lower serratus anterior (LSA) in the arm ER position were significantly higher than those in the neutral position during all tasks. The highest MSA and LSA positions were observed with the arm ER position of 120∘ while standing. CONCLUSIONS: Scapular protraction exercises with arm ER resulted in a higher serratus anterior activity.

Published: June 2021

BACKGROUND: Force perception as a contributor to the neuromuscular control of the knee joint may be altered after anterior cruciate ligament (ACL) injury. OBJECTIVE: This study aimed to compare the force perception accuracy in the knee joints of patients with ACL injury and healthy subjects. METHODS: Twenty-six patients with ACL injury and 26 healthy subjects participated in this case-control study. Participants were asked to produce 50% of the maximum voluntary isometric contraction of the knee muscles as a target force and reproduce it in their limbs in flexion and extension directions. RESULTS: There were significant interactions between group and condition as well as group, condition, and limb in the force perception error respectively (P< 0.05). The highest amount of error was seen in the contralateral limb of the ACL injury group when the reference force was produced in the injured limb (P< 0.05). CONCLUSION: The findings revealed that the force perception accuracy in the knee flexor/extensor muscles of individuals with ACL injury is impaired. Moreover, error is most evident when the patient produces force in the injured limb and replicates it in the uninjured limb in both flexion and extension directions. Therefore, the rehabilitation programs should encompass neuromuscular training in both quadriceps and hamstrings after ACL injury.
A cross-sectional study of disability and quality of life in patients with low back pain: Focus on sex and gender
Authors: Lu Yen-Mou , Chen Chung-Hwan , Lue Yi-Jing
Published: June 2021

BACKGROUND: Sex and gender affect responses to pain, but little is known about disability and quality of life. OBJECTIVES: To investigate the effects of sex and gender on disability and health-related quality of life (HRQOL) in patients with low back pain. METHODS: Ninety-three patients with low back pain were included in this cross-sectional survey study. Disability, HRQOL and gender identity were respectively assessed with the Oswestry Disability Index, Short Form-36 and Bem Sex Role Inventory. The participants were classified into four gender role orientations (masculinity, femininity, androgyny and undifferentiated). One-way analysis of variance was used to analyze both the sex and the gender role orientation. RESULTS: Females had higher disability than males (p< 0.05), but in gender identity, no significant difference was found. Seven domains of HRQOL were lower than the healthy norms. Males experienced greater impacts than females on vitality and mental health (p< 0.05). For gender identity, five domains of HRQOL had significant differences (p< 0.05). Masculinity orientation had the least impact on four domains (p< 0.05), while undifferentiated orientation had the largest impact on all domains. CONCLUSION: Sex and gender effects can be used to analyze disability and HRQOL in patients with low back pain. Females have higher disability, while HRQOL is greatly influenced by different gender role orientations.
Circulating microRNA-762 upregulation in colorectal cancer may be accompanied by Wnt-1/β-catenin signaling
Authors: Lai Peng-Sheng , Chang Wei-Min , Chen Ying-Yin , Lin Yi-Feng , Liao Hui-Fen , Chen Chung-Yu
Published: June 2021

Colorectal cancer (CRC) has become the third most common cause of cancer-related deaths. CRC occurs because of abnormal growth of cells that can invade other tissues and cause distant metastases. Researchers have suggested that aberrant microRNA (miRNA) expression is involved in the initiation and progression of cancers. However, the key miRNAs that regulate the growth and metastasis of CRC remain unclear. The circulating miRNAs from BALB/c mice with CRC CT26 cell implantation were assayed by microarray. Then, Mus musculus (house mouse) mmu-miR-762 mimic and inhibitor were transfected to CT26 cells for analysis of cell viability, invasion, and epithelial-mesenchymal transition (EMT), cell cycle, and regulatory molecule expression. Human subjects were included for comparison the circulating Homo sapiens (human) has-miR-762 levels in CRC patients and control donors, as well as the patients with and without distant metastasis. The result for miRNA levels in mice with CRC cell implantation indicated that plasma mmu-miR-762 was upregulated. Transfection of mmu-miR-762 mimic to CT26 cells increased cell viability, invasion, and EMT, whereas transfection of mmu-miR-762 inhibitor decreased the above abilities. Cells treated with high-concentration mmu-miR-762 inhibitor induced cell cycle arrest at G0/G1 phase. However, mmu-miR-762 did not cause apoptosis of cells. Western blot analysis showed that mmu-miR-762 mimic transfection upregulated the expression of Wnt-1 and β-catenin, as well as increased the nuclear translocation of β-catenin. Further analysis was performed to demonstrate the correlation of miR-762 with CRC, and blood samples were collected from CRC patients and control donors. The results showed that serum has-miR-762 levels in CRC patients were higher than in control donors. Among the CRC patients (n= 20), six patients with distant metastasis showed higher serum has-miR-762 levels than patients without distant metastasis. Conclusions, the present study suggests that circulating miR-762 might be a potential biomarker for upregulation of CRC cell growth and invasion, and may be accompanied by the Wnt/β-catenin signaling.
The predictive potential of Neuronatin for neoadjuvant chemotherapy of breast cancer
Authors: Pieper Willi , Ignatov Atanas , Kalinski Thomas , Haybaeck Johannes , Czapiewski Piotr , Nass Norbert
Published: June 2021

BACKGROUND: Neuronatin (NNAT) determined by immunohistochemistry is a negative prognostic biomarker for breast cancer, independent of the major clinicopathological markers. OBJECTIVE: Here, we investigated whether NNAT is also a predictive biomarker for pathological remission after neoadjuvant chemotherapy. METHODS : One hundred and four breast cancer patients, treated with systemic neoadjuvant chemotherapy were included in this retrospective study. NNAT was detected in formaldehyde fixed, paraffin embedded primary cancer tissue by immunohistochemistry and an immuno-reactive score (IRS) determined. Pathological remission was scored according to Sinn and by evaluation of cytopathic effects. NNAT-IRS was correlated with clinicopathological parameters as well as relapse free and overall survival and for pathological remission after neoadjuvant therapy. RESULTS: NNAT IRS was an independent prognostic marker for relapse free and overall survival and the time from diagnosis to the “tumor-free” state. NNAT IRS was associated with Luminal-A tumors and correlated slightly negative with age and lymph-node metastasis. There was no significant correlation of NNAT-IRS with Sinn’s remission score, but with cytopathic effects of chemotherapy. CONCLUSIONS: We confirmed the prognostic impact of NNAT-IRS in an independent cohort of neoadjuvantly treated patients. Additionally, a correlation with a score for pathological remission under systemic neoadjuvant chemotherapy for breast cancer was found.

Authors: Aref Salah , Ebrahim Lamiaa , El-Ashwah Shaimaa , El Agdar Mohamed , Ayed Mohamed
Published: June 2021

BACKGROUND: Acute myeloid leukemia changes the bone marrow (BM) niche to support leukemia cells by modulating the stromal microenvironment. The aim is to assess Activin-A as a biomarker in acute myeloid leukemia (AML). METHODS: The level of Activin-A and CXCL-12 protein concentration levels in the plasma of bone marrow aspirate samples of eighty AML patients at diagnosis, after induction and at relapse were determined by ELISA. RESULTS: We found that Activin-A concentration levels was significantly up regulated in AML cases at diagnosis, and down regulated at complete remission and rise again at relapse (P< 0.001). In contrast; the CXCL-12 gene expression was significantly down regulated in AML cases at diagnosis; relapse, and up regulated after complete remission (P< 0.001). Multivariate analysis showed that high Activin-A levels at diagnosis is significant predictor of induction of remission response OR 1.006 (CI: 1.002–1.010) (P= 0.003); AML relapse OR 1.002 (CI: 1.0–1.004) (P= 0.043) as well as patients’ outcome OR 1.33 (CI: 1.004–1.062) (P= 0.024). CONCLUSION: Activin-A level at diagnosis is a new simple easily assessed biomarker that could predict AML patient’s response to therapy as well as patient’s outcome.

BACKGROUND: Pyruvate kinase M2 (PKM2) was overexpressed in many cancers, and high PKM2 expression was related with poor prognosis and chemoresistance. OBJECTIVE: We investigated the expression of PKM2 in breast cancer and analyzed the relation of PKM2 expression with chemotherapy resistance to the neoadjuvant chemotherapy (NAC). We also investigated whether PKM2 could reverse chemoresistance in breast cancer cells in vitro and in vivo. METHODS: Immunohistochemistry (IHC) was performed in 130 surgical resected breast cancer tissues. 78 core needle biopsies were collected from breast cancer patients before neoadjuvant chemotherapy. The relation of PKM2 expression and multi-drug resistance to NAC was compared. The effect of PKM2 silencing or overexpression on Doxorubicin (DOX) sensitivity in the MCF-7 cells in vitro and in vivo was compared. RESULTS: PKM2 was intensively expressed in breast cancer tissues compared to adjacent normal tissues. In addition, high expression of PKM2 was associated with poor prognosis in breast cancer patients. The NAC patients with high PKM2 expression had short survival. PKM2 was an independent prognostic predictor for surgical resected breast cancer and NAC patients. High PKM2 expression was correlated with neoadjuvant treatment resistance. High PKM2 expression significantly distinguished chemoresistant patients from chemosensitive patients. In vitro and in vivo knockdown of PKM2 expression decreases the resistance to DOX in breast cancer cells in vitro and tumors in vivo. CONCLUSION: PKM2 expression was associated with chemoresistance of breast cancers, and could be used to predict the chemosensitivity. Furthermore, targeting PKM2 could reverse chemoresistance, which provides an effective treatment methods for patients with breast cancer.

This paper investigates the continuous usage intention of an e-government service from the digital divide perspective, particularly the gender differences. To find out whether the gender difference exists, the case of income tax e-filing service of Pakistan was taken, and the data was collected by means of an online survey from citizens who have previously used tax e-filing service (N = 401). The collected data was analyzed using Welch’s t-test in IBM SPSS v.20. The findings revealed that there is a statistically significant difference between men and women with regards to continuance intention to use income tax e-filing service. Specifically, men are more likely to continue usage than women probably because women are more influenced by their social circle and the ease of use of system while men majorly prefer to use a system for its functional benefits and/or performance. This study contributes to the body of knowledge as the research in the area of gender gap in the e-government usage particularly in a developing country context is scarce. Finally, the results are discussed in the light of the previous research and some practical implications are also provided.
The gendered digital turn: Canadian mayors on social media
Authors: Sullivan Katherine V.R.
Published: June 2021

Women continue to occupy lesser positions of power at all political levels in Canada, although scholars still argue on the accessibility of municipal politics to women. However, no previous study has systematically examined the gender ratio of mayors across Canada, as well as their (active) use of social media platforms in a professional capacity. Using novel data, this study examines the variation in social media adoption and active use by gender outside of an electoral campaign. Results show that there is a higher proportion of women mayors who have a Facebook page, as well as Twitter and Instagram accounts and who actively use them outside of electoral campaigns, when compared with men mayors’ social media practices.

Electronic government (e-gov), a means of providing online public services, has the potential to greatly benefit all members of society. However, its advantages are often out of the reach of citizens who are digitally excluded. Drawing on socioeconomic and demographic ICT survey data, researchers have explored the digital divide and have concluded that gender is an important determinant of inequality. If we are to provide e-gov services that are more accessible to women and geared towards their needs, we must consider the digital gender gap. This paper explores gendered differences in e-gov service usage in Brazil. Findings on the disproportionate numbers of women and men seeking and using e-gov services, as well as the reasons for not using them, justify the relevance of gendering the e-gov debate.
Effect of stern appendages configurations on the course-keeping of ships in stern-quartering seas

Ships can experience serious difficulties in keeping a straight course when sailing in stern-quartering seas. Design modifications like the addition of stern passive fins, or the modification of active control surfaces, are common solutions to improve the ship course-keeping. However, the success of such design modifications depends on the delicate balance between the excitation forces induced by the waves on the appended hull, the stabilization forces provided by the lifting surfaces as appended fins, and the steering forces provided by the control surfaces. This research investigates which of these aspects of a ship design play a concrete role in improving the ship course-keeping in waves. The study is carried out with the intention of looking at the different behaviors of the ship originating from different stern appendages configurations. Three modifications of stern appendages on three different ship hulls were investigated in various mild-to-rough sea conditions. The behavior of the vessels were simulated using a time domain, boundary element potential method, with the addition of semi-empirical formulations for the modelling of the stern lifting surfaces. The simulations were carried out in long crested irregular waves at three different direction, using the JONSWAP spectrum. The results showed that although larger stern appendages improve the directional stability of relatively large and slow vessels, in most cases they worsen their course-keeping ability, increasing the yaw motions. For smaller and faster vessels instead, passive and active fins tend to improve the course-keeping, because at high speed the lift provided by the appendages stabilizes the vessel. This effect is compensated by the wave excitation force at lower speed. Similarly to yaw, the roll motions increases with larger stern appendages.

Background: Cognitive frailty (CF) is identified as one of the main precursors of dementia. Multidomain intervention has been found to delay or prevent the onset of CF. Objective: The aim of our present study is to determine the effectiveness of a comprehensive, multidomain intervention on CF; to evaluate its cost effectiveness and the factors influencing adherence toward this intensive intervention. Methods: A total of 1,000 community dwelling older adults, aged 60 years and above will be screened for CF. This randomized controlled trial involves recruitment of 330 older adults with CF from urban, semi-urban, and rural areas in Malaysia. Multidomain intervention comprised of physical, nutritional, cognitive, and psychosocial aspects will be provided to participants in the experimental group (n = 165). The control group (n = 165) will continue their usual care with their physician. Primary outcomes include CF status, physical function, psychosocial and nutritional status as well as cognitive performance. Vascular health and gut microbiome will be assessed using blood and stool samples. A 24-month intensive intervention will be prescribed to the participants and its sustainability will be assessed for the following 12 months. The effective intervention strategies will be integrated as a personalized telerehabilitation package for the reversal of CF for future use. Results: The multidomain intervention developed from this trial is expected to be cost effective compared to usual care as well as able is to reverse CF. Conclusion: This project will be part of the World-Wide FINGERS (Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability) Network, of which common identifiable data will be shared and harmonized among the consortia.

Background: Neuroprotection against Parkinson’s disease degeneration by photobiomodulation has been reported in animal models but no true placebo-controlled human studies have been published. Objective: To understand if photobiomodulation therapy can produce clinically significant differences in physical performance measures in people with Parkinson’s disease; and what frequency of treatment is necessary to initiate clinical change. Methods: In a participant and assessor-blinded, randomized, placebo-controlled pilot study, 22 participants received either sham and/or active laser photobiomodulation (904 nm, 60 mW/diode, 50 Hz) for 33 s to each of 21 points at the cranium and intra-orally, on one, two or three times/week for 4 weeks. Two treatment phases were separated by a 4-week wash-out (Phase 2). Upper and lower limb physical outcome measures were assessed before and after each treatment phase. The Montreal Cognitive Assessment was evaluated prior to treatment Phase 1, and at the end of treatment Phase 3. Results: Montreal Cognitive Assessment remained stable between start and end of study. No measures demonstrated statistically significant changes. With regular treatment, the spiral (writing) test and the dynamic step test were most sensitive to change in a positive direction; and the 9-hole peg test demonstrated a minimum clinically important difference worthy of further investigation in a larger, adequately powered clinical trial. A placebo effect was noted. Conclusion: The results support the notion that combined transcranial and intra-oral photobiomodulation therapy needs to be applied at least 2 to 3 times per week for at least four weeks before some improvement in outcome measures becomes evident. Longer courses of treatment may be required.
