Over the last five years many middle‐income Latin American countries have seen a steep increase in the number of cases litigating access to curative services. The purpose of this paper is to explore this complex phenomenon and outline some of its roots and impacts.

The authors use an interdisciplinary approach based on a literature review and workshops convened to discuss the issue.

A range of reasons can explain this increased legal activity. These include: a renewed judicial approach to the enforcement of the right to health; a more demanding public interest; an increased prevalence of non communicable diseases; and limited capacity for fair benefit package.

The findings in this paper argue for the need to incorporate a rights‐based approach to health policy as a foundation of societal efforts to achieve universal health coverage in Latin America.

The purpose of this study is to explore the effects of aerospike and hemispherical aerodisks on flow characteristics and drag reduction in supersonic flow over a blunt body. Specifically, the study aims to analyze the impact of varying the length of the cylindrical rod in the aerospike (ranging from 0.5 to 2.0 times the diameter of the blunt body) and the diameter of the hemispherical disk (ranging from 0.25 to 0.75 times the blunt body diameter). CFD simulations were conducted at a supersonic Mach number of 2 and a Reynolds number of 2.79 × 10⁶.

ICEM CFD and ANSYS CFX solver were used to generate the three-dimensional flow along with its structures. The flow structure and drag coefficient were computed using Reynolds-averaged Navier–Stokes equation model. The drag reduction mechanism was also explained using the idea of dividing streamline and density contour. The performance of the aero spike length and the effect of aero disk size on the drag are investigated.

The separating shock is located in front of the blunt body, forming an effective conical shape that reduces the pressure drag acting on the blunt body. It was observed that extending the length of the spike beyond a specific critical point did not impact the flow field characteristics and had no further influence on the enhanced performance. The optimal combination of disk and spike length was determined, resulting in a substantial reduction in drag through the introduction of the aerospike and disk.

To predict the accurate results of drag and to reduce the simulation time, a hexa grid with finer mesh structure was adopted in the simulation.

The blunt nose structures are primarily employed in the design of rockets, missiles, and re-entry capsules to withstand higher aerodynamic loads and aerodynamic heating.

For the optimized size of the aero spike, aero disk is also optimized to use the benefits of both.

The purpose of this paper is to investigate gender differences in organizational commitment (OC) and the relationship between OC and rewards among employees who work for Japanese manufacturing companies within China.

This study utilized hierarchical regression analysis to examine survey data obtained from 27,854 employees who worked for 64 Japanese manufacturing companies within China.

The results reveal that autonomy and role clarity had a stronger influence, and co-worker support had a weaker influence, on OC for male employees than for female employees. These differences may be because more male employees than female employees prefer working with higher autonomy and well-defined roles than with co-worker support. After all, male employees, who place a great emphasis on independence, competition, decision-making and challenges, rely on intrinsic rewards more than social rewards.

This study used data collected from Japanese manufacturing companies to understand the differences between OC and rewards in local male and female Chinese employees. We recommend that future research uses other national affiliates to clarify the characteristics of male and female Chinese workers more objectively and to test the validity of this research.

The results of this study support revising human resource management practices within multinational enterprises to enable female and male host-country workers to contribute to their companies on a long-term basis by taking into account the differences between the cultures of the home and host countries.

Although previous research has elucidated the OC–rewards relationship in particular countries, it has not met the requirements of foreign managers from different corporate cultures who face differences in the OC–rewards relationship between their male and female employees. In this sense, this research is the first attempt to tackle this theme and contribute to the literature.
