Published: April 2024

Khalil Gibran's literary masterpiece "Broken Wings" is a poignant exploration of cultural traditions, social norms, and the intricate dynamics of gender roles in the context of early 20th century Lebanese society. This research delves into the profound themes of the novel, examining how Gibran artfully dismantles prevailing societal constructs and challenges established norms through the lens of the protagonist, Selma Karamy. Central to the narrative is the portrayal of Selma's struggle for autonomy and self-expression within a patriarchal framework that restricts women's agency and confines them to traditional roles. Gibran skillfully exposes the complexities of gender dynamics, illustrating the pervasive influence of societal expectations on individual freedom and fulfillment. Through Selma's introspective journey and unconventional relationship with the protagonist, Gibran invites readers to reflect on the nature of love, duty, and the pursuit of personal liberation. The novel catalyzes reshaping cultural paradigms, advocating for equality and empowerment amidst entrenched social hierarchies. Furthermore, Gibran's lyrical prose and profound insights transcend temporal and cultural boundaries, resonating with readers across generations and continents. By challenging ingrained perceptions and advocating for social transformation, "Broken Wings" emerges as a timeless masterpiece that continues to inspire discourse on gender equality and societal change. This study offers a glimpse into the rich tapestry of themes woven throughout Khalil Gibran's "Broken Wings," highlighting its enduring relevance in fostering dialogue and reshaping cultural traditions and social norms.

Farmers and workers in a state of direct and indirect affectation were identified, that is, those whose agricultural soils are a direct deposit of wastewater and those whose health is affected by the proliferation of insects and the emission of bad odors. The optimum number of surveys was estimated by means of the finite sample equation, taking into account that the size of the study population is 150 people, a confidence level of 95% and a margin of error of 3%. The results showed that there is no environmental management program at the site to solve the problems caused in society. 93% of the population believes that the best solution is the integration of a wastewater treatment and drainage system to significantly reduce the environmental, social and economic impact.

Current agricultural processes require development in harmony with the environment, for this it is necessary to understand all the phenomena that take place in agroecosystems, including the interactions between their components. The objective of the work was to theoretically establish the existing relationship between suburban agriculture, biodiversity, ecosystem services and natural pest control. A bibliographic review was carried out where it was found that suburban agriculture is a form of agriculture that is based on achieving a lower impact on the environment and promoting adequate values of biodiversity. This is important because biodiversity is the basis of agriculture and the source for human beings to satisfy their needs thanks to the ecosystem goods and services it provides. Ecosystem services in turn become tools for producers to manage their farms in a sustainable way using the endogenous resources available to them. Natural pest control is one of the processes that is favored on farms, since there are many groups of organisms, mainly plants, that can provide resources to combat harmful organisms. There is an interdependent relationship between suburban agriculture, biodiversity, ecosystem services, and natural pest control.

INTRODUCTION Cambodia’s exports of goods and services outpaced the country’s economic growth and outperformed global export growth over the past years. Exports of goods and services increased dramatically during the past years, from about US$4.2 billion in 2009 to US$14.7 billion in 2019 (O’Neill, 2021). The solid export growth resulted in improved livelihoods for Cambodian households. Trade is a medium for productivity led growth in a small economy like Cambodia. It gives companies access to wider markets and boosts foreign direct investment. But the COVID-19 pandemic had badly affected the freight forwarding services in Cambodia, and particularly logistics firms, which are involved in the movement, storage, and flow of goods, have been directly affected by the global pandemic. For Cambodia, there was no remarkable gains in freight transport in the early 2020. According to the Cambodia Freight Forwarders Association (CFFA), COVID-19 pandemic has seriously hurt Cambodian logistic providers, with 10-15 percent will soon be bankrupt (VietnamPlus, 2020). As stated by the president of CFFA, “the dramatic decrease in buying orders led the traffic of goods and product exports to drop about 70-80 percent. In addition, more than 100 logistics firms have been struggling to survive due to the financial hardship, with an estimated 60 percent fall in revenue” (VietnamPlus, 2020). Logistics companies connect firms to markets by providing many different services, including transportation, freight forwarding, warehousing and inventory management. They play an important role in global manufacturing, which is complex and multilocational. For example, Apple inc. uses the components from more than 200 supplicrs from many different countries (Ross, 2020). ‘L’oday’s global value chain requires uninterrupted flow of goods between and within the countries. These can be achieved by firms outsourcing their logistics functions to third-party logistics service providers.

El objetivo de este estudio es determinar la calidad de agua lluvia almacenada de los techos de las viviendas de la Asociación de Mujeres Autónomas de Pastaza (AMAP)  para el consumo humano. Se tomaron tres muestras de diferentes viviendas que presentan diferentes tipos de techos (zinc de 2 años, zinc de 10 años y teja de 5 años), los resultados que se obtuvieron se compararon con los parámetros establecidos en la normativa vigente para el consumo humano. Los análisis efectuados demostraron que la composición fisicoquímica y microbiológica del agua lluvia requiere de un tratamiento de potabilización, para estabilizar los valores que sobrepasan los rangos permisibles, entre ellos tenemos el pH de las muestras presentó valores bajos con un promedio de 5.37 lo que determinó que el agua es ácida, como también los altos niveles de coliformes fecales con un promedio de 1.8 nmp/100ml.
