The central part of the pod can be smooth (f. indica), bristly (f. echinatus (Pers.) Rojo) or intermediate. Most Pterocarpus species prefer seasonal weather but P. indicus prefer rainforests. USES The hardwood, which is purplish, is termite resistant and rose-scented. The wood known in Indonesia as amboyna is the burl of the tree, named after Ambon, where much of this material was originally found. Often amboyna is finely sliced to produce an extremely decorative veneer, used for decoration and in making of furniture and keys on a marimba. The flower is used as a honey source while leaf infusions are used as shampoos. Both flowers and leaves were said to be eaten. The leaves are supposedly good for waxing and polishing brass and copper. It is also a source of kino or resin. ...

The Effects of Sin Tax to the Buying Behavior of Smokers in Barangay Narra, San Pedro, Laguna, Philippines

...CHAPTER 1 The Problem and Its Background Introduction Tobacco smoking or cigarette smoking is the practice of burning cigarette, taking the smoke into the mouth and then releasing it. This practice dates back as early as 5,000 – 3,000 B.C. but was introduced to Eurasia in the late 17th century where it has also been a commonly traded product. The practice received speculations and a lot of criticisms since it was first introduced but it somehow made its way inside the society and became widespread upon the invention of automated cigarette-rolling apparatus. The tobacco has been first introduced to other countries before reaching the Philippines. The idea of smoking tobacco first came from the Arawak Indians in 1492 that was noticed by Christopher Columbus. Seven years later, Amerigo Vespucci found out that the inhabitants in an island near Venezuela have already been practicing chewing dried leaves. In 1591, Mexico has already been growing tobacco at an increasing rate. It was believed that the tobacco was introduced by the Spaniards and Portuguese to mainland Europe, East Indies and Asia while they are on an expedition for searching for spices and spreading Christianity. Cigarette smoking became one of the highly sought after vice in the Philippines because of the affordable price of each stick ranging from seventy-five centavos to 2 pesos each, depending on its brand. The Philippine government came up with an idea of increasing the taxes imposed upon alcoholic...

...building, the NARRA Residence Hall. It's an exclusive dormitory for male students of UP Diliman. Anyways, I was with Leo yesterday and he told me that he will go to UP Diliman to bring something for Kiko. Because of not having been there for a long time, I decided to join him and went there from Las Pinas. It was really a tiring ride from the almost southernmost part of Manila to the northernmost part of the region. Leo and I were able to get a cab from Las Pinas and it cost me a lot for the fare... Well, we arrived in UP Diliman at around 8:30 in the evening. We waited for Kiko at Philcoa Jollibee Branch. Just after 15 minutes, I guess, we saw Kiko outside waiving at us with Anton. I felt happy seeing them again after a long time. They told me that Narra is having their OPEN HOUSE that night. Leo told me that he informed me about it but I cant really remember him telling me that. Anyways, I felt a bit bad because I didnt bring my camera with me...and I was only holding my very cheap Nokia 1110i and left my phone camera in my condo. So it was a little frustrating though...I kept on blaming Leo and Leo kept on telling me that he infomed me about it. I guess it was my fault...I'm so damn deaf! Moving on...Leo, Kiko, Anton and I went to a nearby Jeepney Station from Philcoa. While walking towards the station, we saw Christian who's a former dormmate of ours too. I think Kiko informed him about the activity in Narra so he decided to come too. So we all went straight to Narra and arrived...

The Lottery

...Justice is the corner stone of any human civilization, across all nations, all languages, all historical development, all cultural background, and all social groups. Even though human exercises of justice always involve subjective judgment, most people believe that there would be ultimate objective justice in this world. In fact, in any human society, people always ascribe the absoluteness of justice which is free of subjective relativity to divine authority, even if the society is dominated by atheist materialist culture. This is because mankind could only acquire absolute authority from supernatural or divine power superior to all human power. As a result, divine justice has been the foundation of all human justice in this world. Besides the divine justice, there are another two general categories of justice: natural justice and social justice. By natural justice I am referring to the application of natural logic or knowledge when exercising justice. For example, we all know that forcing people to work under dangerous environment or poor conditions could be harmful to them, or cutting a person with knife could kill him. This kind of common knowledge could be accepted among people without any modern scientific education when making judgment about justice. The last major category of justice is the social justice, i.e. the exercise of justice based on various cultural values, human experiences and personal interests. In reality, the process of exercising justice would normally...

Summary: Discrimination Among Asian Immigrants

...The current documented experiences of Asian Indians who either recently immigrated from India or were born and raised in America raise an important question as to whether generational status impacts perceived experiences of discrimination among Asian Indians (Inman et al., 2015; Kaduvettoor-Davidson & Inman, 2013; Tummala-Narra et al., 2011). Kaduvettoor-Davidson and Inman (2013) define first-generation South Asians as “those who immigrated to the United States as adults, whereas second-generation South Asians are those who are either born in the United States or immigrated prior to age 18” (p. 157). The historical significance of Asian Indians’ immigration to the United States begins in understanding the experiences of Indians still living in India. India was colonized and under British imperial rule for 400 years, and this resulted in the internalization of cultural norms and values of British individuals,...

En Arturo la estrella más brillante se narra la historia de un homosexual cubano, que sufre toda clase de humillaciones durante su injusta permanencia en los campos de concentración homosexual, que surgieron en Cuba, durante la Revolución, a mediados de los años sesenta. Este es un texto, cuya escritura es verdaderamente impactante debido a la crudeza con la cual narrador cuenta los hechos por él vividos, durante la dura época en que tuvo que sufrir las humillaciones de la persecución bajo un gobierno opresor; cuya promesa para el pueblo era la de igualdad y libertad, supuestamente. Pero este proyecto de igualdad para el pueblo fue sólo una promesa más sin cumplir por el régimen castrista. El mismo Castro consideró que, en este caso, los homosexuales ó la conducta de estos seres humanos, considerada una desviación; no era digna de un verdadero revolucionario. Así mismo, las personas con este tipo de inclinación sexual eran víctimas de la homofobia y tampoco les era permitido obtener cargos donde la población joven se viera influenciada por ellos. De esta forma, no sólo los homosexuales, sino también aquellos disidentes quienes eran catalogados de antisociales, eran arrestados por los militares...

...1. How can we account for life’s dual nature of unity and diversity? All forms of life have common unifying features yet are amazingly diverse. Both of these facts are a result of our DNA. All life has commonalities, while still being unique. For example insects all have a hard exoskeleton and numerous legs, but they all have different rolls to play on earth, as well as different shapes and sizes. Another good example is humans. We're all built with the same general composition, but each of us are unique within those boundaries. 2.

Critic to Homer

...La Ilíada una controversia como hecho histórico La Ilíada es un antiguo poema épico dividida en veinticuatro cantos. A través de ellos se narran los últimos tiempos del ataque de Troya. Se dice que la guerra de Troya se originó cuando el príncipe de Troya, Paris, raptó a la esposa de Agamenón, rey de Esparta. Esta guerra duro diez años. Desde la época clásica de Grecia hasta las generaciones de hoy día, se considera la Ilíada como una de las composiciones literarias mas importante de la Antigua Grecia. Esta poesía se le atribuye al poeta griego Homero. La Ilíada es un tema de constante debate ya que muchos historiadores, filósofos, antropólogos, en fin, muchos intelectos creen que este poema no narra algo verdadero y se preguntan si esta guerra de Troya verdaderamente ocurrió o si simplemente es un mito, una fantasía o pura ficción El debate comienza desde el propio autor Homero. Hoy día no se sabe a ciencia cierta si fue un autor o varios autores los creadores de la Ilíada. Juan Carlos Rodríguez en su libro “El desarme de la cultura. Una lectura de la Ilíada” alega que debido al determinante peso de esta tradición oral épica la Ilíada no pudo ser obra de un solo autor (Rodríguez, 2010, p.21) . Marco S. De Veri comenta que Homero ha sido el compositor, o al menos, el recopilador de la Ilíada y que no solo multiplicó esas tradiciones trasmitidas oralmente, si no que fue quien las organizó (Veri, 2004, p.21). Friedrich August Wolf argumenta que la épica homérica es una...
