The Impact of Corporate Social Responsibility on Regulatory Comment Letters: Evidence from Iran
Authors: Hesarzadeh Reza 
Published: January 2022

Securities commissions regularly review corporate reports, and if the review reveals a possible deficiency— such as a potential accounting error— or requires further clarifications, they send the company a comment letter (CL), including a request for providing written responses and relative additional information. Current study aims to examine whether and how corporate social responsibility (CSR) affects CLs. This empirical study is based on a sample of 437 Iranian firm year observations from 2011 to 2017. Results show that firms with more CSR are less likely to receive CL, that more CSR does not influence the association of managerial misbehavior and CLs, and that the negative association between CSR and CLs is stronger among firms facing higher environmental information asymmetry and firms having higher corporate governance quality. Collectively, this paper contributes to the literature by providing new evidence on the beneficial effect of CSR in the context of CLs.
Las comisiones de valores revisan periódicamente los informes de las empresas, y si la revisión revela una posible deficiencia -como un posible error contable- o se requiere más aclaraciones, envían a la empresa una carta de comentarios (CL), que incluye una solicitud de respuesta por escrito y la relativa información adicional. El presente estudio pretende examinar si la Responsabilidad Social de las Empresas (RSE) afecta a las cartas de comentarios y cómo lo hace. Este estudio empírico se basa en una muestra de 437 observaciones anuales de empresas iraníes desde 2011 hasta 2017. Los resultados muestran que las empresas con más RSC tienen menos probabilidades de recibir CL y que más RSC no influye en la asociación entre mal comportamiento de los directivos y CL. También se pone de manifiesto que la asociación negativa entre RSC y CL es más fuerte entre las empresas que enfrentan una mayor asimetría de información ambiental y las empresas que tienen una mayor calidad de gobierno corporativo. En conjunto, este trabajo contribuye a la literatura aportando nuevas pruebas sobre el efecto beneficioso de la RSC en el contexto de las CL.

Authors: Li Xiaoping , Ren Yanli , Liu Donghong , Yu Xi , Chen Keda 
Published: January 2022

Objective
To inquiry about mechanism of miR-100-5p/CDC25A axis in breast carcinoma (BC), thus offering a new direction for BC targeted treatment.

Methods
qRT-PCR was employed to explore miR-100-5p and CDC25A mRNA levels. Western blot was employed for detecting protein expression of CDC25A. Targeting relationship of miR-100-5p and CDC25A was verified by dual-luciferase assay. In vitro experiments were used for assessment of cell functions.

Results
In BC tissue and cells, miR-100-5p was significantly lowly expressed (P < 0.05) while CDC25A was highly expressed. Besides, miR-100-5p downregulated CDC25A level. miR-100-5p had a marked influence on the prognosis of patients. The forced miR-100-5p expression hindered BC cell proliferation, migration and invasion, and facilitated cell apoptosis. Upregulated miR-100-5p weakened promotion of CDC25A on BC cell growth.

Conclusion
Together, these findings unveiled that CDC25A may be a key target of miR-100-5p that mediated progression of BC cells. Hence, miR-100-5p overexpression or CDC25A suppression may contribute to BC diagnosis.

Authors: Cerlyawati Hugi , Isworo Slamet 
Published: January 2022

Objective and Background: The Gonjol river serves as a lifeline for the communities surrounding Demak's brackish water ponds. Currently, factory waste is poisoning rivers. The purpose of this research was to investigate the levels of heavy metals Pb and Cu in Wideng crab tissue, water, and sediment in the Gonjol river's upper course and estuary.
Methods: This study was place from January to March 2020. Heavy metal concentration was determined using atomic absorption spectroscopy. The linear regression method was used to analyze the data.
Results: Except for Cu in upstream and estuary sediments, the concentration of Pb and Cu in the waters, sediments, and Wideng crab tissue remained below the acceptable limits. Heavy metals Pb and Cu in both sediment and tissue did not reveal a significant association in the upstream and estuary, although there was a correlation between water and tissue. There is no association between silt and water in the upstream and estuary. The river's quality is based on the Decree of the Minister of the Environment of the Republic of Indonesia No.115 of 2003, which places it in category C, which means it has moderate levels of Pb and Cu pollution. While tissue and sediment levels are below the tolerance limit.
Conclusion: The state of the Gonjol River is a source of concern, particularly the circumstances of Cu and Pb, which allow bioaccumulation in the future, posing a threat to the ecosystem and the communities surrounding it.

Authors: Bhojwani Muskan , Patil Shubhangi , Deshpande Shruti 
Published: January 2022

Background: Cyclic Mastalgia affects women who are menstruating in their 20s, 30s, or 40s. This pain starts about a week before commencing menstruation. During this period, the breasts become sore, tender, and swollen, though symptoms improve later in the cycle or it may be so severe that the patients cannot wear tight fitting clothes or they becomes irritable. The discomfort usually occurs outside and upper portions of both breasts, and it may even affect underarms. Cyclical Mastalgia is a common condition associated with a higher risk of breast cancer. Mastalgia is common ailment that affects about 70% of women and has negative impact on their quality of life. Many scientists believe that the cause of cyclic mastalgia lies in a mix of hormonal activity and something in the breast that reacts to it. Mastalgia is a term used to describe women's discomfort with their breasts, although doctors usually neglect it.
Methods: Based on the inclusion and exclusion criteria, a total of 30 women will be selected for the study. A questionnaire of breast pain based on the McGill Pain Questionnaire, and a Cardiff chart, will all be employed as outcome measures. The individuals' pre-intervention scores will be collected, and they will be given an exercise routine to follow for four weeks, three times per week. The outcomes of the intervention will be measured afterwards. Our protocol will cover weeks of treatment. Reqular assessment will be carried out.
Discussion: This study was done to find out effectivness of exercise program in obese womens with breast mastalgia and tenderness.

Authors: Daniel Ogbebor , John Ugbebor N. , Yusuf Momoh O. L. , Onyedikachukwu Ndekwu B. 
Published: January 2022

Aim: The study aimed at modeling the concentration of pollutants along soil profile using finite element method.
Study Design: Data was generated from the laboratory on the concentrations of selected heavy metals at varying depths of land discharged slaughterhouses. This was used to estimate the level of nutrient build-up in the soil within these environs, hence, used to verify and validate the finite element analysis. The model upon validation was used to predict the rate of pollutant build-up in the soil within the slaughterhouses discharge areas.
Methodology: A total of twelve composite samples were collected from three different land discharged locations. The three composite samples each were collected from the sampling locations at a depth of 0 to 10cm, 10 to 20cm, 20 to 30cm and 30 to 40cm. Four composite samples each were collected for analysis from the three sampling locations on specified sampling dates. The samples were then placed in sterile polythene bags and transported to the laboratory for processing. The laboratory results obtained for heavy metals were used for the generated model verification and validation, hence predictions for pollutants accumulation was done on a time step.
Results: Model verification showed a good fit of a nonlinear polynomial curve for both the measured and predicted values with R² values of 0.9978 to 0.9985 for zinc and 0.9978 to 0.9984 for lead at a selected time step of 15years. It was observed however, that there was an increasing tendency to uniformity of concentration as the time step increased; this was due to parameters build-up with time in the soil.
Conclusion: Finite element results revealed a high build-up in the concentration of pollutants (Zinc and Lead) in the land discharged slaughterhouses.

Published: January 2022

AbstractStretchable encapsulation plays a crucial role in expanding the applications of flexible electronics, particularly the large‐area flexible displays. In this work, polydimethylsiloxane (PDMS) hybrid films with high stretchability, excellent transparency, and good barrier property are achieved by a simple process of SiO2 doping and atomic layer infiltration (ALI). The doped SiO2 improves the mechanical property and serves as reaction sites for the Al2O3 infiltration. A clear “nucleation‐filling‐coating” mechanism of Al2O3 ALI is proposed and elaborated in detail by in situ quartz crystal microbalance. The optimized PDMS hybrid films exhibit a relatively low water vapor transmission rate (WVTR) value of 1.81 × 10−3 g m−2 day−1 and excellent mechanical reliability, where after 1000 cycles of the fatigue stretching test at 1% tensile strain the WVTR only slightly increases to 2.01 × 10−3 g m−2 day−1. Furthermore, the patterned quantum dots encapsulated with PDMS hybrid films still retain more than 50% photoluminescent intensity even after the stretching and storage in deionized water for 2400 h, which is ≈80 times longer than the pristine ones. Therefore, the proposed combined method of SiO2 doping and ALI modification has great and practical implications for stretchable encapsulations for future flexible electronics.

Published: January 2022

AbstractIn the present study, mono‐ and multi‐material laser textured Ti6Al4V implants are manufactured and characterized in vivo to explore their applicability in orthopedic implants. Laser surface texturing is used for manufacturing grooved Ti6Al4V implants while a pressure‐assisted sintering technique is employed to impregnate beta‐tricalcium phosphate into grooves for an improved bioactivity. After implantation into Sprague Dawley rat's femur for 4 and 12 weeks, bone‐implant fixation and osseointegration are assessed, by performing push‐out tests and histological characterization. Histological characterization showed bone formation around all implants, characterized by immature bone at 4 weeks of implantation and a more mature bone after 12 weeks. The maximum push‐out forces are higher for the textured and multi‐material solution, when compared to non‐textured implants right after 4 weeks of implantation (p < 0.05). After 12 weeks, multi‐material implant displayed higher fracture energy when compared to non‐textured implants (p < 0.05). Results revealed that laser surface texturing and bioactive multi‐material solutions are highly effective to promote bone regeneration and enhance bone‐implant fixation for further application in orthopedic implants.

Published: January 2022

AbstractCu halide materials with low electronic dimension show great scintillation properties with high photoluminescence quantum yield (PLQY) and large Stokes shift, which can result in reabsorption‐free scintillators. However, there is still a need for a large‐scalable method to fabricate large amount of scintillation powder and large‐size scintillation films. In this regard, a high scintillation yield Cu3Cu2I5−PDMS flexible film utilizing ball‐milled Cu3Cu2I5 powder is developed. The ball‐milled Cu3Cu2I5 powder shows a high PLQY of 74.5%, narrow emission peak of 80 nm and good ambient stability, demonstrating the potential of ball‐milling method for large‐scale scintillator production. Furthermore, the Cu3Cu2I5−PDMS film shows even high PLQY exceeding 90%, which may be ascribed to the passivation effect of PDMS resulting in a little longer carrier lifetime. The flexible Cu3Cu2I5−PDMS film can further deliver high spatial resolution of 6.8 lp mm−1@0.2 MTF in X‐ray imaging and good stability under steady X‐ray illumination. This work demonstrates that the ball‐milling method could be an effective approach for large‐scale fabrication of low electronic dimensional scintillation materials.

Published: January 2022

AbstractDesign and implementation of efficient p‐type transparent conducting (TC) oxides with excellent performance are the global material challenge. The strategy of “chemical modulation of the valence band” triggers the enthusiasm for p‐type TC delafossite CuMO2. However, the low conductivity of previous CuMO2 films obstructs the development of delafossite‐based electronics. Herein, a new p‐type 4d transition metal Rh‐based CuRhO2 film with large‐size is first designed and fabricated by a facile solution method. Room‐temperature conductivity as high as 735 S cm−1 is achieved by substituting 10%Mg in Rh sites. Additionally, the acceptor‐doped CuRhO2 films exhibit high near‐infrared transmittance of 85–60% with low room‐temperature sheet resistance of 4.28–0.18 kΩ sq−1. Furthermore, the electronic structure, electrical transport mechanism, and intra‐band excitation feature for the CuRhO2 film are unveiled. The theoretical and experimental results make a great advance in p‐type TC films and will pave a promising blueprint for future multifunctional opto‐electronic devices.

Published: January 2022

AbstractChiral organic ligand‐incorporated low‐dimensional metal‐halide perovskites have received increasing attention for next‐generation photodetectors because of the direct detection capability of circularly polarized light (CPL), which overcomes the requirement for subsidiary optical components in conventional CPL photodetectors. However, most chiral perovskites have been based on low‐dimensional structures that confine chiroptical responses to the ultraviolet (UV) or short‐wavelength visible region and limit photocurrent due to their wide bandgap and poor charge transport. Here, chiroptical properties of 3D Cs0.05FA0.5MA0.45Pb0.5Sn0.5I3 polycrystalline films are achieved by incorporating chiral plasmonic gold nanoparticles (AuNPs) into the mixed PbSn perovskite, without sacrificing its original optoelectronic properties. CPL detectors fabricated using chiral AuNP‐embedded perovskite films can operate without external power input; they exhibit remarkable chirality in the near‐infrared (NIR) region with a high anisotropy factor of responsivity (gres) of 0.55, via giant plasmon resonance shift of chiral plasmonic AuNPs. In addition, a CPL detector array fabricated on a plastic substrate demonstrates highly sensitive self‐powered NIR detection with superior flexibility and durability.
Long‐term yield response of corn, wheat, and double‐crop soybean to tillage and N placement

Published: January 2022

AbstractOn claypan soils of the eastern Great Plains, yield of no‐till crops often lags yield of crops grown with tillage, especially cereals requiring sound N management. The objective of this 14‐yr study was to determine the yield response of corn (Zea mays L.), winter wheat (Triticum aestivum L.), and double‐crop soybean [Glycine max (L.) Merr.] in a 2‐yr rotation to tillage system and N fertilizer placement. Tillage, N placement, or their interaction affected corn yield in all seven‐corn crop‐years. Corn yields averaged about 25% lower with no‐till than with conventional or reduced tillage and were never greater with no‐till in any year. Nitrogen fertilization increased corn yield by increasing kernels per ear; however, corn yield increase to subsurface band (knife) N applications compared with surface (broadcast or dribble) applications was only about 10%. In the lower‐yielding no‐till system, corn yield increase to knifed N fertilization was greater than in tilled systems and may partially ameliorate the no‐till yield decline. Average wheat yield was unaffected by tillage. Adding N more than doubled wheat yield, but differences in wheat yield between preplant N placements methods were small. Average double‐crop soybean yield was unaffected by tillage with few, inconsistent differences by year. Compared with no‐till, tillage tended to increase soil P and K, but soil organic matter was just redistributed with no net increase with no‐till. Thus, tillage and N placement treatments may affect corn but have lesser effects on wheat and double‐crop soybean and soil properties in this rotation.
