Some researchers are now focusing on learning about how adolescents view their own relationships and sexuality; they want to move away from a research point of view that focuses on the problems associated with adolescent sexuality.[why?] College Professor Lucia O'Sullivan and her colleagues found that there weren't any significant gender differences in the relationship events adolescent boys and girls from grades 7-12 reported. Most teens said they had kissed their partners, held hands with them, thought of themselves as being a couple and told people they were in a relationship. This means that private thoughts about the relationship as well as public recognition of the relationship were both important to the adolescents in the sample. Sexual events (such as sexual touching, sexual intercourse) were less common than romantic events (holding hands) and social events (being with one's partner in a group setting). The researchers state that these results are important because the results focus on the more positive aspects of adolescents and their social and romantic interactions rather than focusing on sexual behavior and its consequences.
Why do researchers believe the social event reporting by adolescents (rather than sexual activity) is important?
focus on the more positive aspects of adolescents

Despite the position of the official organizations, an opinion poll carried out between 2001 and 2004 showed that the majority of the Valencian people consider Valencian different from Catalan. This position is promoted by people who do not use Valencian regularly. Furthermore, the data indicates that younger generations educated in Valencian are much less likely to hold these views. A minority of Valencian scholars active in fields other than linguistics defends the position of the Royal Academy of Valencian Culture (Acadèmia de Cultura Valenciana, RACV), which uses for Valencian a standard independent from Catalan.
How many scholars outside of linguistics agree with the Royal Academy?
A minority

Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. Green laser pointers outputting at 532 nm (563.5 THz) are relatively inexpensive compared to other wavelengths of the same power, and are very popular due to their good beam quality and very high apparent brightness. The most common green lasers use diode pumped solid state (DPSS) technology to create the green light. An infrared laser diode at 808 nm is used to pump a crystal of neodymium-doped yttrium vanadium oxide (Nd:YVO4) or neodymium-doped yttrium aluminium garnet (Nd:YAG) and induces it to emit 281.76 THz (1064 nm). This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus (KTP), whose non-linear properties generate light at a frequency that is twice that of the incident beam (563.5 THz); in this case corresponding to the wavelength of 532 nm ("green"). Other green wavelengths are also available using DPSS technology ranging from 501 nm to 543 nm. Green wavelengths are also available from gas lasers, including the helium–neon laser (543 nm), the Argon-ion laser (514 nm) and the Krypton-ion laser (521 nm and 531 nm), as well as liquid dye lasers. Green lasers have a wide variety of applications, including pointing, illumination, surgery, laser light shows, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons and bird control.
Which color of lasers are widely available to the general public?
