Puffy hand syndrome involves the complications of lymphatic system due to its clogging or destruction. The researchers invented a study of cases and established their controls (Andresz et al., 2006). They balanced the cases through gender basis and interviewed drug addicts on different aspects such as history of drug abuse and buprenorphine use. In their study, they refer to a past study in France (Andrez et al., 2006). In the conclusion, the study finds out that HDSB use was not a causal factor of puffy hand syndrome in women.

They, however, realize that sex, absence of tourniquet and admission in the feet causes puffy hand syndrome in women (Andresz et al., 2006). The study extensively relied on data obtained from practical tests; a fact that makes it very accurate and objective. For instance, they say that the median of buprenorphine injection period was 3.5 years. The study also eliminates bias by presenting cases that their solutions could not be found. For example, they do not establish the reason behind the issue of more women than men having puffy hand syndrome (Andresz et al., 2006). Additionally, researchers pinpoint the benefit of puffy hand syndrome.

Apart from this, the study considered diverse aspects like tobacco use and demographic factors. Visual data in research This study is concerned in emphasizing the significance of use of visual data. The researchers lay the foundation of their analysis by stating that vision in a child precedes words. They explain that seeing first creates our world and environment (Fitzgerald & Rhodes, 2006). However, in most qualitative research most of those involved in the study utilize interviews at the expense of vision.

The argument proposes that there could be a greater utilization of visual data. The author isolates, for instance, the role of visual information to an ethnographer. He argues that a recorded visual data is accurate and provides the scenario for subsequent multiple analysis (Fitzgerald and Rhodes, 2006). It is essential that the author denotes the recent growth of video technology in promoting the essence of healthy lifestyles. Finally, the author relays the importance of visual data in addiction research.

First, he notes that visual capture of information can ensure the inclusion of a detail ignored by audio data. Besides, visual data impacts positively in the memory. Finally, he states that visual data is enduring an, therefore, becomes open to secondary evaluation. It is essential to note that the author emphasizes his argument by providing an example of injecting practices among drug users. This study possesses certain limitations. To begin with, it over-relies on sociological data like the growth of a child (Fitzgerald & Rhodes, 2006).

The study does not involve control cases to relay the possibilities of a contradiction to hypothesis. Phobia in schools This third study involves the issue of different phobias that students undergo. The authors present a case study where they aim at solving a given phobia while utilizing cognitive tests. Underlying facts is given on the case of phobias. From previous statistics, it is reported that particular phobias account for the third in rank of mental disorder. These disorders possess negative social and work complications.

However, previous research has dwelt on exposure therapy as the mode of treatment to these disorders. (Adler & Nobbs, 2011)The authors
