Unit 5 Literature Synthesis

The synthesis concerns real published studies; the Corliss application is composite and illustrative.
Why Organize by Claim
A literature review organized author by author tells a reader what each study found but leaves the reader to work out what the studies show together. Organizing by claim does that work: each section states a claim, brings in every study that bears on it, says where they agree and disagree, and ends by judging how firmly the evidence supports the claim. The seventeen studies identified in Unit 3 are distributed across three claims, along with a small number of other sources that bear directly on them.
Claim One: Supervisors Shape How Seriously a Crew Treats Safety
The strongest line of evidence comes from research on group safety climate. Zohar (2000) proposed that work groups form shared perceptions of the priority their own supervisor gives safety relative to speed or output, and that these group-level perceptions differ within a single organization. In a manufacturing company, he found that groups' climate scores predicted their rates of minor injuries in the months that followed. Zohar and Luria (2005) extended the model, showing that organization-level and group-level climates are related but distinct, and that supervisors' own practices account for differences between groups working under the same company policies.
Experimental evidence supports a causal reading. Zohar (2002) gave supervisors feedback on how often their daily interactions concerned safety and found that minor injuries fell and safety behavior improved in their groups. In a different industry, Kines et al. (2010) trained construction foremen to talk about safety more often in daily conversations and found improvements in site safety levels. Meta-analytic evidence places these studies in a broader pattern: Christian et al. (2009) found that safety climate was among the strongest situational predictors of safety performance and was related to accidents and injuries.
Griffin and Neal (2000) distinguished two kinds of safety performance that climate can influence: compliance, following required procedures, and participation, voluntary actions such as reporting hazards or helping coworkers. That distinction matters for Corliss, because near-miss reporting is a form of participation.
How firmly supported: strongly. Correlational and experimental studies in several industries agree, though most experiments are small.
Claim Two: Newcomers Carry Sharply Higher Injury Risk
Breslin and Smith (2006) analyzed data on Canadian workers and found that those in their first month on a job had several times the risk of a lost-time injury of workers with more than a year of tenure, a gradient that held across age groups and occupations after adjusting for other factors. Newness to a job, not youth alone, carried the risk.
Temporary agency workers combine newness with a second complication. They work under a host employer's supervision while employed by an agency, and federal guidance from OSHA and NIOSH stresses that host employers must treat temporary workers' training and hazard protection as their responsibility too, in practice as well as on paper (Occupational Safety and Health Administration & National Institute for Occupational Safety and Health, 2014). Few of the studies in the seventeen addressed agency workers directly, but those that reported tenure found injuries concentrated early.
How firmly supported: strongly for newness; moderately for the specific situation of agency temporaries, where evidence is thinner.
Claim Three: Tested Interventions Have Used Stable Crews
This claim is built from what the intervention studies have in common rather than from what any one of them reports. In Zohar's interventions, in the construction foreman study and in the other supervisory studies among the seventeen, work groups appear to have been stable over the study period, with supervisors working with largely the same people throughout. None reported crews in which a large share of members changed during the intervention, and none examined whether the intervention's effect depended on crew stability.
That matters because the mechanism the studies propose works through shared perceptions within a group. If a third of a crew is replaced every two months, as happens on some Corliss lines, those perceptions may not form, or may have to be rebuilt continually. The intervention might still work, by changing how supervisors talk to each newcomer, or it might fail, because the group climate it depends on never stabilizes.
The evidence shows that supervisors can change a crew's sense of safety; it has not yet shown whether they can when the crew keeps changing.
How firmly supported: as a claim about a gap, strongly, since it rests on the absence of a condition across the studies. As with any claim about absence, a study the search missed could weaken it.
Where the Claims Interact
The three claims are not independent, and the synthesis is most useful where they meet. Claims one and two together suggest a specific mechanism for Corliss: if newcomers are at highest risk, and supervisors shape a crew's sense of how seriously safety is taken, then the supervisor's communication with newcomers in their first weeks should matter more than communication with experienced associates, who have already formed their view of what the supervisor expects. None of the seventeen studies separated supervisors' communication with new and experienced workers, so this combined prediction is untested.
Claims one and three meet at the level of measurement. Group climate is measured by averaging crew members' perceptions, and the studies justify averaging by showing that members of the same group agree. In a crew where a third of members are new, agreement may be low simply because newcomers have not yet formed a view, which would make the climate measure itself unstable. Any study in high-churn crews will need to report agreement within crews and consider measuring newcomers' perceptions separately.
The Synthesis Table
A table in the appendix maps each of the seventeen studies against the three claims, coding each cell as support, qualification, contradiction or no bearing. Every study bears on claim one or claim three; four bear on claim two. None contradicts claim one, two qualify it by reporting effects only for some outcomes, and none contradicts claim three.
What the Synthesis Supports
Taken together, the three claims define the Corliss project's place in the literature. The mechanism is established. The risk among newcomers is established. What is not established is whether the mechanism works in the high-churn crews where newcomer risk concentrates. That is the question the project should ask, and the interaction between the claims suggests it should look most closely at what supervisors say to associates in their first weeks on the line.

GB890 Unit 5 instructions, in plain terms
The fifth GB890 assignment asks you to synthesize the literature into claims that support your project. Explain why you are organizing by claim rather than by author. For each claim, state it, gather all the studies relevant to it, say where studies agree and disagree, and end with a judgment of how firmly the evidence supports it. Allow a study to appear under more than one claim where it bears on several. Build at least one claim from what studies have in common rather than from what any one reports, if that is where the gap lies. Examine where claims interact, since predictions often sit at their intersection. Provide a table mapping each study against the claims. Close with what the claims together establish and what they leave open. Nine pages under claim headings, with a synthesis table, is a typical scope for this assignment.
How the GB 890 Unit 5 example is put together
The synthesis opens by explaining the claim structure. Claim one moves from Zohar's group-level model and the cross-level work of Zohar and Luria to the 2002 intervention, the construction foreman study and Christian and colleagues' meta-analysis, then adds Griffin and Neal's compliance and participation, ending with a strong rating. Claim two presents Breslin and Smith's tenure gradient and federal guidance on host employers, rating newness strongly and agency evidence moderately. Claim three, built from the shared feature of stable crews, carries the highlighted sentence. A section on where claims interact predicts that communication with newcomers matters most and flags agreement problems in climate measures. The synthesis table and a closing statement of what is established complete it.
Where the points sit in the GB890 Unit 5 rubric
Points in the GB890 synthesis go to argument rather than coverage. Instructors give credit for claims stated clearly and supported by every relevant study, with agreement and disagreement noted. A closing judgment of support for each claim is expected and weighted. Reusing studies across claims shows synthesis rather than summary. A claim built from a shared feature of the literature, such as stable crews, earns credit when it is argued carefully, including the limits of a claim about absence. Examining where claims interact demonstrates depth. A synthesis table lets the committee check the mapping. The conclusion should state precisely what the claims establish and leave open. Accurate citation of all studies is required throughout the paper.
GB890 Unit 5 help from the desk
Many GB890 syntheses are literature reviews in disguise, with one paragraph per study and no claims. Others state claims but support each with a single study. Students often fail to judge how firmly each claim is supported. Gaps are asserted rather than built from the literature's shared features. Interactions between claims are rarely examined, though they often yield the project's sharpest predictions. Synthesis tables are frequently missing. State each claim, gather every relevant study, note agreement and disagreement, judge support, reuse studies where they fit, build the gap from what studies share, examine interactions and map studies in a table. If your search is complete, we can help you organize the synthesis.

Whatever the search turned up, listed roughly, plus the Unit 5 instructions and rubric, is enough to begin. The synthesis sent back sorts those studies into claims, places each where it supports, qualifies or contradicts, and adds a table making that placement checkable. A first order, which lands in 24-48h, is not billed.

GB890 Unit 5 questions, answered
How is a synthesis different from a literature review?
A literature review can summarize studies one at a time; a synthesis combines them to make claims no single study makes. The test is whether each paragraph says something about the field rather than about one paper. Organizing by claim forces that, because a claim heading cannot be supported by a single summary however detailed it is.
What goes in a synthesis table?
Studies as rows, claims as columns, and a mark in each cell showing whether the study supports, qualifies or contradicts that claim, sometimes with a short note. It lets a reader check the prose against the evidence at a glance. Some sections also add columns for design and sample, which helps expose patterns such as every intervention study using stable crews.
Can one study support more than one claim?
Yes, and strong syntheses reuse studies that way. A single intervention study might support the claim that supervisors shape crew safety and also illustrate the stable-crew pattern behind the gap. Reusing a study across claims signals a review organized by argument; if every study appears exactly once, the organization may still be by author underneath.
Where can I find a free GB890 Unit 5 sample paper?
This page holds a full GB890 Unit 5 literature synthesis on supervisors and production-line safety, organized around three claims with a judgment of support for each.
What is the difference between safety compliance and safety participation?
Griffin and Neal described compliance as following required procedures and participation as voluntary actions that support safety, such as reporting hazards or helping coworkers.
