Five little boys have been raped and killed in the past three weeks. All of them have died due to strangulation with a rope. There were no other person's fingerprints or body fluids on the bodies. The boys all lived in an area of Memorial Drive in Dekalb County. The police fear the killer will attack again. What specialist is needed to find or identify the killer and predict where he might strike next? Why?

Forensic biologist

Explanation:

The specialist needed to find or identify the killer would be a forensic biologist. A forensic biologist uses trace samples or evidence in identifying victims and/or suspects and generally supporting criminal investigations with the aid of scientific techniques. In the case described in the question, there are other samples (aside from body fluids and fingerprints) that can be obtained from the crime scene; for example, in the case of a struggle with the killer, some of the boys could have pulled hair strands from the killer. The root of these hair-strand can be subjected to DNA analysis to identify the killer. There is also the possibility of having one of the boys scratching some skin cells from the killer; these could also be useful in DNA analysis.

The forensic biologist could also determine when and where the actual death of the boys took place, this information could be vital for the law enforcement in predicting where the killer might strike.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
