Sample Solution

Latent prints are impressions produced by the ridged skin, known as friction ridges, on human fingers, palm, and soles of the feet. Examiners analyze and compare latent prints to known prints of individuals in an effort to make identifications or exclusions. The uniqueness, permanence, and arrangement of the friction ridges allow examiners to positively match two prints and to determine whether two friction ridge impressions originated from one source. The most common method of developing latent prints on nonporous objects is to physically enhance them by applying fingerprint powder. Fingerprint powder is composed of many different ingredients that can vary greatly depending on the formula used.

some positional power, usually by establishing a clear hierarchal structure. By establishing a hierarchy, the leader is perceived by the group to be able to make demands and expect compliance from them giving the leader legitimate power (French and Raven, 1959). Secondly, by providing the leader with the ability to reward compliance and punish non compliance from the group, the leader has reward and coercive power (French and Raven, 1959). To obtain complete power over the group the leader must gain the trust and belief of the group that they are capable of success, by ensuring the group are both satisfied and meeting performance goals.
The importance of establishing a hierarchy became evident during the planning stage of the outdoor management course for the red team, the coordinators within the team assumed leadership roles but were unable to gain positional power due to the team being a peer group (Pettinger, 2007). The leaders selected had little authority and influence over the group as everyone was perceived to have the same rank, status and occupation, hence the leaders had none of French and Ravens five bases of power (Pettinger, 2007). The result was leaders with no positional power over the group, so could not direct the group with the method of leadership required for the situation. The task had significant constraints, particularly a short time frame and a large group size, for this situation Chelladurai recommends an autocratic leadership style would be most favourable (Chelladurai and Madella, 2006). The leaders attempted an autocratic leadership style, setting individual tasks for the group, however due to the poor leader member relations and lack of positional power the leadership structure quickly became a democracy. The product was an extremely unproductive workforce initially because of the time spent discussing how was best to approach the task
