Tensions between the demands of the knowledge-based economy and remaining, blue-collar jobs underlie renewed debates about whether schools should emphasize career and technical training or college-preparatory curricula. We add a gendered lens to this issue, given the male-dominated nature of blue-collar jobs and women's greater returns to college. Using the ELS:2002, this study exploits spatial...
Microscopic methods were used to investigate the unique collar structure of the gram-negative sulfate-reducing bacterium, strain DCB-1. Polar cell growth apparently occurred from the collar. When the daughter cell was approximately equal in length to the mother cell and the collar was thus centrally located, cell division occurred within the collar region. Division was by a novel mechanism whic...
White collar crime is the least studied and the least understood crime type in comparison to traditional crime types. This review highlights the recent developments in the state of knowledge over the white collar criminals. The review concerns the topics of demography, motivation for offending and career criminality among white collar criminals. It compiles the international results (mainly Wes...
Although white collar work is of vast importance to the economy, the Operations Management (OM) literature has focused largely on traditional blue collar work. In an effort to stimulate more OM research into the design, control and management of white collar work systems, this paper provides a systematic review of disparate streams of research relevant to understanding white collar work from an...
Running title: CTS in blue-collar workers and housewives ABSTRACT Objectives: We compared rates of surgically treated CTS among blue-/white-collar workers and housewives in the general population. Methods: We estimated numbers of surgically-treated cases of idiopathic CTS among 25–59-year-old residents of Tuscany, Italy, during 1997–2000 (when out-of-hospital CTS surgery was extremely rare), ba...
A stiff collar can restrict atlantoaxial instability in rheumatoid cervical spine in selected cases.
OBJECTIVE To study the efficiency of a stiff collar in restricting the instability of anterior atlantoaxial subluxation (AAS). METHODS Twenty two successive patients with an unstable AAS were studied. Lateral view radiographs were taken of the cervical spine in flexion, extension, and neutral positions without a collar, and in full flexion with a custom made stiff collar. RESULTS The collar...
in this paper the effectiveness combination of bed sill and collar in reduction of local scour depth at cylindrical piers under clear water flow condition was investigated (v/vc=0.9). in the first of experiments, the bed sill was located in downstream and different distances from the piers. results indicated that minimum distance of the bed sill from the piers in downstream has maximum reductio...
The livestock protection collar (LP Collar) i: one of the few technical innovation: developed over the past 20 years fog managing coyote depredation on livestock Invented by Roy McBride in 1970, the LF Collar was researched at length by the Denver Wildlife Research Center (DWRC; and several cooperators before being approved for use with Compound 1080 by the U. With this transfer, the LP collar ...
The purpose of this study was to test the hypothesis that blue-collar workers have an increased risk of coronary heart disease. Subjects were 653 male (mean age, 32.6 years) and 492 female (mean age, 26.3 years) workers employed during 1993 at a computer manufacturing company. The measurements determined were body mass index (BMI), waist to hip ratio (WHR), skinfold thickness, blood pressure, g...
BACKGROUND Blue-collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce. OBJECTIVES To investigate allergic contact dermatitis in blue-collar workers with dermatitis registered by the Danish Contact Dermatitis Group. METHODS A retrospective analysis of patch test data from 1471 blue-collar workers and 1471 matched controls tested between 20...
