Background

In this study, the measurement of job stress of electric overhead traveling crane operators and quantification of the effects of operator and workplace characteristics on job stress were assessed.

Methods

Job stress was measured on five subscales: employee empowerment, role overload, role ambiguity, rule violation, and job hazard. The characteristics of the operators that were studied were age, experience, body weight, and body height. The workplace characteristics considered were hours of exposure, cabin type, cabin feature, and crane height. The proposed methodology included administration of a questionnaire survey to 76 electric overhead traveling crane operators followed by analysis using analysis of variance and a classification and regression tree.

Results

The key findings were: (1) the five subscales can be used to measure job stress; (2) employee empowerment was the most significant factor followed by the role overload; (3) workplace characteristics contributed more towards job stress than operator's characteristics; and (4) of the workplace characteristics, crane height was the major contributor.

Conclusion

The issues related to crane height and cabin feature can be fixed by providing engineering or foolproof solutions than relying on interventions related to the demographic factors.

<![CDATA[Domestic Violence in the Canadian Workplace: Are Coworkers Aware?]]> https://www.researchpad.co/product?articleinfo=5b02c4a7463d7e5da8171ad7

Background

Domestic violence (DV) is associated with serious consequences for victims, children, and families, and even national economies. An emerging literature demonstrates that DV also has a negative impact on workers and workplaces. Less is known about the extent to which people are aware of coworkers' experiences of DV.

Methods

Using data from a pan-Canadian sample of 8,429 men and women, we examine: (1) awareness of coworker DV victimization and perpetration; (2) the warning signs of DV victimization and perpetration recognized by workers; (3) whether DV victims are more likely than nonvictims to recognize DV and its warning signs in the workplace; and (4) the impacts of DV that workers perceive on victims'/perpetrators' ability to work.

Results

Nearly 40% of participants believed they had recognized a DV victim and/or perpetrator in the workplace and many reported recognizing more than one warning sign. DV victims were significantly more likely to report recognizing victims and perpetrators in the workplace, and recognized more DV warning signs. Among participants who believed they knew a coworker who had experienced DV, 49.5% thought the DV had affected their coworker's ability to work. For those who knew a coworker perpetrating DV, 37.9% thought their coworker's ability to work was affected by the abusive behavior.

Conclusion

Our findings have implications for a coordinated workplace response to DV. Further research is urgently needed to examine how best to address DV in the workplace and improve outcomes for victims, perpetrators, and their coworkers.

<![CDATA[Tumor Associated Macrophage: A Review on the Phenotypes, Traits and Functions]]> https://www.researchpad.co/product?articleinfo=5ad8b912463d7e5dccd660cf

The macrophages role within the tumor microenvironment has amended by a variety of factors, thus serves a vital role in tissue morphogenesis. The role of macrophages in health and disease differs enormously as the macrophage has shown dual functions. Macrophage has a basic role in antigen presentation serving as the first line of defense in diseases. However the presence of cytokines and growth factors, both together have regulated the macrophage to become negative effectors promoting tumor activity. Hence macrophages are a double edged weapon, and any imbalance in the regulatory mechanisms caused a shift from tumoricidal to tumorigenic activities. TAMs would be the main reason of the invasion in tumor microenvironment enhancing as well as tumor invasion, angiogenesis and metastasis promoting tumor genesis. Macrophages are the multifunctional cells which have conducted by the tumor cells to produce tumor promoting factors that enable the stimulation of angiogenesis, and tumor cell invasion. This fact has resulted initiation or promotion of tumor genesis, where the tumor has progressed to an upper malignant stage. The present review has focused on the tumor associated macrophages and their roles in tumor genesis.
