Journal Article Review About Stress In Universities, Students Article Journal Article Review About Stress In Universities, Students – Article Example This paper reviews the article d â€Å"Relationship between stress coping levels of and their probability of committing suicide† (Ug˘urlu and Ona) taken from EBSCO. The article begins with a discussion of the process of stress which entails three phases of reaction to the alarm, resistance and exhaustion. The article points to the fact that individuals with an internal locus of control have higher self-confidence and can better handle stress. These individuals are less likely to commit suicide as opposed to those who blame situational factors for their failure (external locus of control). Studies conducted have discovered a direct relation between university students and depression, anxiety, stress, suicide and adaptation issues. The primary research used by authors of this article included a survey of 350 health students of the University of MuÄŸla (Ug˘urlu and Ona). After having analyzed the results of the research, the authors concluded that there was a high correla tion between suicide and stress levels of university students. Furthermore, findings revealed that the stress-coping ability of males was higher compared to females which have implications on suicide levels ultimately (Ug˘urlu and Ona). However, the research provided some contradictory insights with respect to gender and suicide levels; contrary to previous research results, this one proved that the chances of committing suicide were higher among males than females (Ug˘urlu and Ona). Since the research was conducted with respect to health students, the results also revealed that the ability to cope stress was higher for nursing department’s students than health officer students (Ug˘urlu and Ona). Another interesting insight that was revealed was that there was a direct relation between the students’ ability to cope stress and mother’s education level (Ug˘urlu and Ona). The higher the mother’s education level, the higher the student’s ab ility to deal with stress. Furthermore, it was discovered that students with single parents also suffered from social isolation which was a significant factor behind suicide (Ug˘urlu and Ona).

Large Crane Flies, Family Tipulidae

Large Crane Flies, Family Tipulidae Large crane flies (Family Tipulidae) are indeed large, so much so that most people think theyre giant mosquitoes. Theres no need to worry, because crane flies dont bite (or sting, for that matter). Please note that members of several other fly families are also referred to as crane flies, but this article focuses only on the large crane flies classified in the Tipulidae. Description: The family name Tipulidae derives from the Latin tipula, meaning water spider. Crane flies are not spiders, of course, but do appear somewhat spider-like with their extraordinarily long, slender legs. They range in size from tiny to large. The biggest North American species, Holorusia hespera, has a wingspan of 70mm. The largest known tipulids   inhabit southeastern Asia, where two species of Holorusia measure a whopping 10 cm or more in wingspan. You can identify crane flies by two key features (see this interactive labelled image of each ID feature) First, crane flies have a V-shaped suture running across the upper side of the thorax. And second, they have a pair of conspicuous halteres just behind the wings (they look similar to antennae, but extend from the sides of the body). Halteres work like gyroscopes during flight, helping the crane fly stay on course. Adult crane flies have slender bodies and a single pair of membranous wings (all true flies have one pair of wings). Theyre typically unremarkable in color, though some bear spots or bands of brown or gray. Crane fly larvae can withdraw their heads into their thoracic segments. Theyre cylindrical in shape, and slightly tapered at the ends. They generally inhabit moist terrestrial environments or aquatic habitats, depending on the type. Classification: Kingdom - AnimaliaPhylum - ArthropodaClass – InsectaOrder – DipteraFamily - Tipulidae Diet: Most crane fly larvae feed on decomposing plant matter, including mosses, liverworts, fungi, and rotting wood. Some terrestrial larvae feed on the roots of grasses and crop seedlings, and are considered pests of economic concern. Though most aquatic crane fly larvae are also detritivores, some species prey on other aquatic organisms. As adults, crane flies are not known to feed. Life Cycle: Like all true flies, crane flies undergo complete metamorphosis with four life stages: egg, larva, pupa, and adult. Adults are short-lived, surviving just long enough to mate and reproduce (usually less than a week). Mated females oviposit either in or near water, in most species. Larvae may live and feed in the water, underground, or in leaf litter, again, depending on the species. Aquatic crane flies usually pupate underwater, but emerge from the water to shed their pupal skins well before sunrise. By the time the sun rises, the new adults are ready to fly and begin searching for mates. Special Behaviors and Defenses: Crane flies will shed a leg if needed to escape the grasp of a predator. This ability is known as autotomy, and is common in long-legged arthropods like stick insects and harvestmen. They do so by means of a special fracture line between the femur and trochanter, so the leg separates cleanly. Range and Distribution: Large crane flies live throughout the world, with over 1,400 species described globally. Just over 750 species are known to inhabit the Nearctic region, which includes the U.S. and Canada. Sources: Borror and DeLongs Introduction to the Study of Insects, 7th Edition, by Charles A.
