Evaluating interaction with websites: Case study of a government website of the Brazilian Ministry of labor and employment

This paper presents a usability evaluation of the MTE (Ministry of Labor e Employment) website in order to measure the effectiveness, efficiency and user satisfaction regarding the website. The participants were 12 users (07 users were female and 05 male). The results indicate that although the education level of all participants and computing experience, many of them have had difficulty in finding information and do not recommend the site. © 2013 Springer-Verlag Berlin Heidelberg.

Division of labor between M and P visual pathways: different visual pathways minimize joint entropy differently

Visual perception and action are strongly linked with parallel processing channels connecting the retina, the lateral geniculate nucleus, and the input layers of the primary visual cortex. Achromatic vision is provided by at least two of such channels formed by the M and P neurons. These cell pathways are similarly organized in primates having different lifestyles, including species that are diurnal, nocturnal, and which exhibit a variety of color vision phenotypes. We describe the M and P cell properties by 3D Gábor functions and their 3D Fourier transform. The M and P cells occupy different loci in the Gábor information diagram or Fourier Space. This separation allows the M and P pathways to transmit visual signals with distinct 6D joint entropy for space, spatial frequency, time, and temporal frequency. By combining the M and P impacts on the cortical neurons beyond V1 input layers, the cortical pathways are able to process aspects of visual stimuli with a better precision than it would be possible using the M or P pathway alone. This performance fulfils the requirements of different behavioral tasks.

A Dynamic Approach to Stakeholder Theory: A Case Study of Labor - Management Relations at General Motors

The purpose of this thesis is to identify areas for improvement in the current stakeholder management literature. The current stakeholder management theories were analyzed to determine their benefits and detriments. To determine how these theories work in a corporation, General Motors was selected as a single-case study to determine the patterns of stakeholder management over time. These patterns demonstrated the need for dynamic stakeholder management over time, with an emphasis on collaboration and the necessity of recognizing the greater stakeholder network surrounding the corporation. Proper stakeholder management in the early years of General Motors would have prevented its failure, while the organizational culture as a path-dependent variable made it difficult for General Motors to alter long-standing stakeholder relationships.

Oral misoprostol for third stage of labor: a randomized placebo-controlled trial

OBJECTIVE: To investigate whether orally administered misoprostol during the third stage of labor is efficient in reducing postpartum blood loss. METHODS: In a double-masked trial, during vaginal delivery women were randomly assigned to receive a single oral dose of misoprostol (600 microg) or placebo in third stage of labor, immediately after cord clamping. The third stage of labor was managed routinely by early cord clamping and controlled cord traction; oxytocin was administered only if blood loss seemed more than usual. Blood loss was estimated by the delivering physician and differences in hematocrit were measured before and after delivery. RESULTS: Mean (+/- standard error of the mean) estimated blood loss (345 +/- 19.5 mL versus 417 +/- 25.9 mL, P = .031) and hematocrit difference (4.5 +/- 0.9% versus 7.9 +/- 1.2%, P = .014) were significantly lower in women who received misoprostol than those who received placebo. Fewer women in the misoprostol group had postpartum hemorrhage (blood loss of at least 500 mL), but that difference was not statistically significant (7% versus 15%, P = .43). Additional oxytocin before or after placental separation was used less often in the misoprostol group (16% versus 38%, P = .047). There were no differences in the length of third stage of labor (8 +/- 0.9 minutes versus 9 +/- 1 minutes, P = .947). There were no differences in pain during third stage of labor, postpartum fever, or diarrhea, but shivering was more frequent in the misoprostol group. CONCLUSION: Oral misoprostol administered in the third stage of labor reduced postpartum blood loss and might be effective in reducing incidence of postpartum hemorrhage.

A comparison of labor and delivery management activities in two settings

Similarities and differences in management activities and patient health outcomes between a traditional physician staffed labor and delivery setting and a certified nurse-midwife staffed Birth Center within the same hospital were described. The 950 study subjects, low income, minority women, were classified as low obstetrical risk by a POPRAS score of 25 points or less at time of admission for labor and delivery. The study subjects were similar in demographic, antepartum and intrapartum characteristics; the labor course was problem free for the majority in both settings. There were no remarkable differences in health outcomes between the groups. Management activities varied between settings; these variations were policy related rather than health related. The POPRAS rating system was an accurate predictor for 93% of BC subjects and 85% of LDU subjects. Charge for service was approximately $600 less for BC women; length of stay did not contribute to the difference in charge. Overall, BC respondents to the attitude survey were more satisfied with their labor and delivery experience than L\&DU women. ^

The Changing Nature of Employment and the Reform of Labor and Social Security Legislation in Post-Apartheid South Africa

This paper tries to understand the current status of South African labor market, which is changing in contradictory directions, i.e. a strengthening of the rights and protection of workers at the same time as the flexibilization of employment, in the context of the characteristics of labor and social security legislation in South Africa, as well as the nature of labor and social security reforms after democratization. We put emphasis on the corporatist nature of labor policy-making as the factor influencing the course of reforms; it is argued that the apparently contradictive changes can be explained consistently by the corporatist labor policy-making process which has been practiced notwithstanding the problem of representativeness.
