Para ello se emplea una metodología de búsqueda sistemática en tres bases de datos internacionales de alto impacto, de las que fue posible identificar y seleccionar 64 trabajos científicos con los cuales se construye el estado de la cuestión. El análisis de estos documentos confirma, de manera significativa, una tendencia a que las empresas que desarrollan políticas y prácticas de gestión ambiental obtienen mejor reputación y mayores utilidades y resultados financieros. Los hallazgos de este trabajo son útiles tanto para el sector productivo como para la academia en cuanto revelan; para los primeros, los efectos positivos de la implementación de estrategias ambientales y; para los segundos, el avance en el desarrollo teórico y la consolidación de agendas para futuras investigaciones.
(Neo)liberalismo, producción y criminalización de la pobreza ((Neo)liberalism, production and criminalization of poverty)
Authors: Quijano Valencia Olver
Published: August 2023

*Autor invitado de honor.Contra la sensación de cómo las actuales e históricas relaciones sociales desiguales constituyen una suerte de condiciones naturales e imperativos propios del desenvolvimiento y reacomodo del sistema capitalista, en la presente reflexión se indaga críticamente sobre las nuevas y cínicas manifestaciones del capitalismo neoliberal. Se aborda el neoliberalismo como discurso y modelo civilizatorio y como práctica gubernamental; igualmente se analiza la (re)producción de la pobreza, la inseguridad y la sensación de inseguridad, la erosión del trabajo remunerado/estable y su conversión en inseguridad ontológica, y en suma, el tratamiento de la pobreza y la marginalidad como problemas de criminalidad.Paradójicamente, numerosas acciones desde los nuevos aparatos filantrópicos estatales combinados con la intensificación y severidad del sistema penal dan cuenta del desinterés global por abordar, nutrir y consolidar un proyecto de democratización social, capaz de contraponerse a los imperantes regímenes de ´fascismo social´ y de ´apartheid global´. Comprender estas nuevas y hasta sutiles estrategias también es indispensable a la hora de pensar en transformaciones sustantivas de la sociedad y en favor de la producción y de la reproducción de la vida.Palabras clave: proyecto ontológico, subjetividad, tecnología de gobierno, marketing de sí mismo, marginalidad, criminalización de la pobreza.

Contabilidad pública: ¿Instrumento de gobierno neoliberal de las poblaciones? (Public accounting: Neoliberal governance instrument of populations?)
Authors: Ocampo Salazar Carmen Alejandra
Published: August 2023

Se presenta una relexión sobre la contabilidad pública y su relación con el gobierno de las poblaciones. Michel Foucault plantea que la comprensión de los contextos históricos es determinante para entender la constitución de los sujetos. Por ende, la definición de la contabilidad como dispositivo de control, como dispositivo disciplinario o como tecnología de gubernamentalidad se deben estudiar desde su conexión histórica. En el ámbito gubernamental la contabilidad asume una u otra forma, dependiendo de la racionalidad política imperante en un determinado momento histórico. En esta perspectiva se reconocen cambios y transformaciones del Estado de Bienestar hacia un Estado Neoliberal en los últimos 30 años; un cambio de racionalidad política que implicó el traslado de lógicas empresariales, entre ellas la contabilidad para el gobierno público.

Research on the Influence of Monetary Policy on Stock Market Return
Authors: Sun Ruize
Published: August 2023

These changes in China's stock market are influenced by factors such as the share-trading reform and the international financial crisis. During this period, a series of monetary policies implemented in China also had some profound effects on China's stock market. Capital market has always been the main transmission channel of monetary policy. In recent years, China's interest rate system, share-trading system and other reforms have been gradually implemented, and the reform of interest rate marketization has achieved certain results, but it has also brought more uncertainty to the transmission of stock market and monetary policy. With the continuous expansion of the stock market, it has played an important role in the transmission process of monetary policy. At the same time, monetary policy can affect the price of financial assets, thus changing people's behavioral decisions and achieving monetary policy goals. When the actual monetary policy changes beyond or below expectations, it will cause the change of stock price. The existence of expectation effect makes the relationship between monetary policy and stock price change more complicated: taking loose monetary policy as an example, when the actual degree of easing is greater than investors' expectations, stock prices will be positively stimulated by easing; When the degree of easing is less than investors' expectations, the stock price will turn downward. Therefore, it is worth studying to analyze the influence mechanism among monetary policy, stock market and real economy.

Published: August 2023

This paper addresses the key issues in house price forecasting from multiple perspectives by establishing a house price forecasting model for Guangzhou city, providing valuable information and decision support for home buyers, developers, and the government. First, this paper employs the Person coefficient, stepwise regression model and t-test to address the problem of quantifying data and exploring house price factors. By analyzing the correlation between the relevant variables and house prices, the key characteristics that have significant and strong correlation effects on house prices are obtained. Second, the K-means clustering model was used to classify houses into three categories: economic houses, comfortable houses and high-end houses. This classification result provides a more detailed data base for the subsequent construction of the house price prediction model. Finally, the random forest house price prediction model was established in this paper, and the model was validated by error analysis and stability analysis. The average absolute value error and goodness-of-fit obtained were 0.08 and 0.92, respectively, indicating that the model has high accuracy and reliability. The research in this paper has important implications for all parties, including home buyers, developers, and the government. For home buyers, the model can help them better understand the market situation; for developers, the model can guide their reasonable pricing and development strategies; for the government, the model can provide a scientific basis for real estate market regulation and policy control to promote market stability and sustainable development.

Authors: Wang Kaiwen , Shen Yijun , Duan Mingzhang , Wu Tairan , Zhao Jiaqi , Wang Ji
Published: August 2023

Fluorinated materials have been broadly used in the industry of water repellent and stain resistance. Because fluorinated materials have low surface tension, and the coatings could easily be manufactured as water-repellent and stain-resistant, fluorinated materials dominate the market for breathable waterproof textiles. However, these materials had substantial health hazards because of the toxicity of fluorinated materials. Moreover, many governments also regulate fluorinated materials for health reasons. As a result, non-fluorinated materials replacing fluorinated materials have become a trend in the industry. As a result, many companies are actively looking for solutions for non-fluorinated water-repellent and stain-resistant materials. This literature review will give a comprehensive understanding of water-repellent properties, materials surfaces, and stain-resistance properties, materials, and surfaces.Moreover, this review would also include reviews of natural water repellent and stain repellent. Furthermore, this review will also talk about the theories behind the materials. Additionally, the fabrication process limitation and future outlook will be discussed in this review.

Published: August 2023

Solid fouling settlement, defined as the unexpected payment of various types of solid contaminants, including ice, wax, bacteria, and protein, can result in many problems in daily life and production and cause economic and security losses. Despite many traditional methods for reducing foulant to make a more durable and efficient antifouling surface, many artificial surfaces inspired by the natural antifouling material which the environment has selected during the process of evolution, including lotus leaf, pilot whale skin, gecko feet, shark skin, and pitcher plant are developed to resist adhesion of multiple foulants in an efficient and environmentally friendly way. In this review, the mechanism of how surfaces using patterns similar to the natural antifouling surface resist fouling materials is overviewed. Various methods for fouling formation classify the hazard, properties, and characteristics of different fouling materials. The approaches typically applied in designing a surface with high fouling resistance are presented first. After interpreting the theories and models mentioned in the explanation of the fouling resistance property, the textural microstructures, the chemical and physical properties used, and applications for fouling resistance of several bio-inspired fouling resistance surfaces, and how these surfaces can be improved in the future are discussed.

Investigation of golf course chemical and herbicide contamination
Authors: Tan Dewei
Published: August 2023

In golf course management, fertilizers and herbicides are often used to maintain the healthy growth of green and fairway grass. Using these chemicals often comes with the drawback that they tend to leech into local water bodies, from where they are dispersed outside of the golf course, harming organisms. In this study twelve water samples were collected from two golf courses in Shanghai and tested them from several indicators such as total, chemical oxygen demand, and common herbicides. The experiment found that the total nitrogen in each of the twelve samples exceeds the level rated for drinking and industrial use. Levels of chemicals other than nitrogen, however, resembles those rated for drinking water reserves, while herbicide levels are borderline undetectable. Results from this study provide insight regarding the identification of pollutant based on the abnormality of some indicators, helping golf course management in achieving eco-friendliness.
A wet impregnation approach to synthesize MIL-101(Cr) with open metal sites and their application in the adsorption of volatile organic compounds
Authors: Peng Xinyi
Published: August 2023

The simple wet impregnation method reported a series of MIL-101(Cr) materials doped with copper acetate paddle wheel species. Powder X-ray diffraction and SEM studies showed the MOF frameworks remained intact during wet impregnation, and SEM- EDX, XPS, and N2 adsorption analyses confirmed the successful copper acetate loading. Volatile organic compounds adsorption capabilities of these materials were further examined, and it found that copper acetate doped MIL-101 (Cr) possesses up to 61% improvement in toluene uptake as compared to pristine MIL-101 (Cr) at a low partial pressure of P/P0 = 0.10 under 298.1 K. This performance improvement is attributed to the unsaturated open metal sites introduced by molecular copper acetate with a paddle wheel structure. This study provides not only a new series of promising VOC removal MOFs with unsaturated Cu(II) open metal sites but also a simple, widely applicable method for introducing Cu(II) open metal sites into MOFs by using molecular copper species with predefined paddle wheel structure.

Authors: Prabhakar Gautham , Gonuguntla Rishi K. , Momtaz David , Chaput Christopher , Hogue Grant D.
Published: August 2023

Ehlers-Danlos syndrome (EDS) is a rare inherited connective tissue disorder characterized by collagen synthesis disruption, resulting in joint hyperlaxity, skin and vascular fragility, and bleeding diathesis. Patients with EDS are susceptible to spinal deformities, with scoliosis accounting for up to 23.4% of musculoskeletal abnormalities. Conservative management is often trialed initially; however, severe scoliosis can lead to significant sagittal imbalance and cardiopulmonary compromise. Surgical intervention for scoliosis correction in patients with EDS presents unique challenges because of tissue fragility and an increased risk of vascular and wound complications. This case report discusses a 20-year-old man with type II EDS and scoliosis, who experienced retroperitoneal compartment syndrome, significant left lower extremity weakness, and loss of sensation after scoliosis correction surgery. The report also provides an overview of the existing literature on scoliosis surgery outcomes in patients with EDS, highlighting the need for heightened vigilance and cautious surgical approaches.

Published: August 2023

Objective: To determine the effect of functional claw trimming versus blunt claw trimming on the gait of sows. Materials and methods: Nineteen sows (PIC C29) were transported to the research center and claws were trimmed 3 times over an 8-day period. Dewclaws were trimmed even with the coronary band of the hoof on day 1. Claws were blunt trimmed on day 4 and functional trimming occurred on day 8. The gait of each sow was recorded prior to each trimming to compare the effect of the previous trimming. A final gait recording was taken on day 12. The gait data collected from the sows was compared across days to determine if any changes occurred. Results: Positive improvements in gait data were noted after dewclaw trimming. Changes were seen in velocity (P = .03), stride length (P = .02), stride duration (P = .04), stance (P = .04), and rear percent stance (P = .03). Blunt trimming offset the improvement gained by trimming dewclaws, seen in the changes to rear percent stance (P = .02) and front swing (P = .04). Functional trimming increased the improvement observed by trimming dewclaws. Changes were seen in the stance (P < .001), percent stance (P < .001), stride duration (P = .003), stride length (P = .008), and velocity (P = .003). Implications: Trimming dewclaws and functionally trimming claws improved the sow’s gait. Blunt trimming did not provide the same benefits observed by trimming dewclaws or functionally trimming the claws.

Published: August 2023

Objective: To evaluate the effects of daily oral dose of Bacillus subtilis C-3102 to nursing piglets on fecal consistency, fecal microbes, and preweaning performance in a controlled trial. Materials and methods: A total of 26 litters of nursing piglets were assigned to receive a daily oral dose of placebo (n = 14 litters) or probiotic (n = 12 litters) for 18 days beginning on day 2 after birth until weaning on day 19. The probiotic treatment was B subtilis C-3102 (Calsporin, Calpis Co Ltd). Treatments were applied orally once daily to individual piglets via 1 mL sugar-based gel solution alone (placebo) or with B subtilis C-3102. Growth performance and litter size were measured on days 2, 9, 16, and 19. Fecal scoring and sampling were performed on days 2, 9, and 16 to categorize fecal consistency and conduct microbial analysis by isolation and enumeration method. Results: There was no statistical difference (P > .05) on growth performance, litter size, mortality, and fecal consistency in the preweaning period between placebo- and probiotic-treated litters. The numbers of B subtilis C-3102 (P < .001), total Bacillus species (P < .001), and total aerobes (P = .03) were increased in litters receiving probiotic compared to placebo. The numbers of Lactobacillus species, Enterococcus species, Clostridium perfringens, and Enterobacteriaceae were not influenced by treatment. Implications: A daily oral dose of B subtilis C-3102 probiotic did not influence preweaning growth performance and fecal consistency of nursing piglets and only influenced Bacillus species fecal microbial population.

Objective: This study assessed the efficacy of nebulization (NEB), also known as fogging, to expose gilts to Mycoplasma hyopneumoniae under field conditions as a potential acclimation strategy. Materials and methods: Phase I consisted of 448 M hyopneumoniae-free gilts from four different batches of a gilt development unit (GDU). On study day 0, batches 1 and 2 were exposed to M hyopneumoniae-positive lung homogenate via intratracheal (IT) route and were used as reference for batches 3 and 4, which were exposed using a mechanical fogger. Tracheobronchial swabs (TBS) were collected at 2 and 4 weeks post exposure (D14 and D28, respectively) and infection success was assessed by real-time polymerase chain reaction of pooled samples. In phase II, 1160 gilts from the same GDU belonging to three different batches (5 to 7) were exposed to M hyopneumoniae via NEB, and TBS were collected at D14. Results: In phase I, no statistically significant differences were observed between IT and NEB exposure in proportion of positives and mean cycle threshold values of TBS pooled samples at any time point (D14 and D28). In phase II, TBS pooled samples from all batches were positive for M hyopneumoniae at D14. Implications: Nebulization of lung homogenate positive for M hyopneumoniae resulted in infection of commercial gilts with this pathogen. Therefore, the use of NEB may be a reliable M hyopneumoniae exposure method under field conditions. The information generated in this investigation broadens the understanding of this technology as an acclimation strategy.

Objectives: To determine the effect of heat lamps versus heat mats on piglet performance measures, sow lying behavior, piglet behavior, and energy use. Materials and methods: Seventeen multiparous crossbred sows housed in farrowing stalls were randomly assigned to one of two heat source treatments: Baby Pig Heat Mat - Single 48 (MAT; n = 8) or Poly Heat Lamp Fixture (LAMP; n = 9). Piglets were weighed on day 1 and at weaning and any mortalities were recorded to evaluate piglet production measures. For 7 days over the course of lactation (day 1, 2, 3, 4, 5, week before weaning, and day before weaning), sows and their litters were observed for 2 hours twice daily to evaluate behavior. Electric meters were attached to individual heat source units to monitor energy use. Results: Piglet production parameters were unaffected by treatment type; litter weaning weight (P = .85), litter average daily gain (P = .79), and preweaning mortality (P = .58). Piglet behavior had variation in the number of piglets using a heat source within day across treatments (P < .001). The number of piglets in contact with the sow decreased during early lactation for both treatment types and increased during late lactation with more MAT pigs tending to be in contact with the sow (P < .001). Implications: Using heat mats as supplemental heat in the farrowing house may result in decreased energy use and increased savings without hindering piglet production parameters.

Objective: Evaluate the effectiveness of a staged market pig loading procedure for reducing contaminant transfer from livestock trailers to the barn. Materials and methods: A conventional loading procedure was compared to a staged procedure, with 10 replicates each. In the staged procedure, one loadout crew member was stationed between two lines of separation and could not cross onto the livestock trailer or into the center alleyway of the barn. The remaining loadout crew members within the barn could not cross into the loadout alleyway or chute. In the conventional procedure, a loadout crew member moved pigs from the center alleyway, through the loadout alleyway, and up the chute, but did not cross onto the livestock trailer. Fluorescent powder was mixed with obstetrical lubricant and wood shavings and spread evenly on the livestock trailer floor, just inside the roll-up door that opens to the chute. After each loadout, fluorescent powder contamination was evaluated at 8 locations: one in the chute, two in the loadout alleyway, and five in the center alleyway of the barn. Results: Four of five center alleyway locations had significantly lower contamination (P < .05) for the staged protocol compared to the conventional protocol. The level of contamination at the fifth center alleyway location was not statistically different (P = .057). The contamination level at all other locations was not statistically significant between the two groups (P > .05). Implications: The staged loading procedure effectively reduced the transfer of fluorescent powder from the livestock trailer to the barn.

Objectives: This study aimed to evaluate the physiological and behavioral responses of pigs administered sodium nitrite, determine an ideal dosing rate by oral drenching of sodium nitrite for depopulation events, and evaluate the nitrite residue present in the ocular fluid and skeletal muscle after sodium nitrite administration. Materials and methods: Four groups of 10 market weight pigs (40 market weight pigs total) and 1 group of 10 sows were used. Each group of market weight animals received a different oral drench dose of sodium nitrite solution (1× [400-441 mg/kg], 2× [800-882 mg/kg], 2.5× [1000-1102 mg/kg], and 3× [1200-1323 mg/kg]) and was observed for distress behaviors. Two market weight animals in each treatment group were implanted with a monitor to measure body temperature, heart rate, and activity levels. The dosing rate with apparent best behavioral and physiological response was applied to the 10 sows and the same behaviors monitored. After death was confirmed, ocular fluid and skeletal muscle samples were collected from the sows. Results: An increased dosage of sodium nitrite greatly reduced the time to distress with a significant linear relationship. A higher frequency of vocalizations and the most frequent spikes in activity levels were observed in the lowest dosing group. No correlation was found between ocular fluid nitrite and skeletal muscle sodium nitrite concentrations. Implications: Oral drenching of sodium nitrite is a viable method for swine depopulation events. Higher doses of sodium nitrite have better welfare associations. Ocular fluid nitrite anion concentrations do not correlate with sodium nitrite skeletal muscle concentrations.
