What are the main concerns of human resource managers in organizations?

[EN] Purpose: This study examines whether high involvement work programs (HIWP) are included in, and respond to, the priorities of HR managers in organizations. We analyze reports to identify the main concerns for managers, and compare the solutions implemented to address them, to evaluate the extent to which HIWP are adopted to meet these challenges. Design/methodology: To conduct this study we carried out a systematic literature review, selecting reports by consulting firms and human resource management associations. Findings: Our key findings from this research suggest that HIWP are used as a lever for change to meet the challenges faced by HR managers in organizations, the most urgent of which are talent management and improving leadership. Research limitations/implications: The paper identifies possible lines of research that respond specifically to the interests of the professional ambit and would be better appreciated by HR managers in companies. Practical implications: The issues raised are relevant to HR professionals, allowing them to compare their priorities against those of managers occupying similar positions, and to view a selection of the most commonly used programs to solve priority problems. This enables HRMs to plan ahead and prepare by providing them with an overview of the most important challenges they have to face. Originality/value: On the one hand in the professional arena, as they provide professionals with an overview of the challenges they face, so they can plan optimal HR management programs, work methods geared and identify improvement opportunities. And on the other hand, in the academic sphere, our study opens possible future research lines that may contribute to the development of the profession, identify research lines that genuinely address the concerns of professionals and could help reduce the gap that some researchers have identified between the academic and professional spheres.Juarez-Tarraga, A.; Santandreu Mascarell, C.; Marin-Garcia, JA.

Ileoileal intussusception secondary to angiofibrolipoma

Intussusception is an uncommon cause of intestinal occlusion in adults, accounting for 1-5% of the causes. In this group it is important to rule out malignant tumors as the primary cause of intussusception. This pathology is explained by the invagination of a segment of the intestine onto itself. The clinical manifestations are those typical of intestinal occlusion. Within the study protocol, the CT scan shows the target sign or sausage image depending on the slice. Surgical management will be necessary in order to re-establish intestinal transit and remove tumors. We present the case of a 45-year-old woman with upper intestinal occlusion secondary to ileoileal intussusception due to submucosal angiofibrolipoma

Dynamic Control of a Novel Planar Cable-Driven Parallel Robot with a Large Wrench Feasible Workspace

Cable-Driven Parallel Robots (CDPRs) are special manipulators where rigid links are replaced with cables. The use of cables offers several advantages over the conventional rigid manipulators, one of the most interesting being their ability to cover large workspaces since cables are easily winded. However, this workspace coverage has its limitations due to the maximum permissible cable tensions, i.e., tension limitations cause a decrease in the Wrench Feasible Workspace (WFW) of these robots. To solve this issue, a novel design based in the addition of passive carriages to the robot frame of three degrees-of-freedom (3DOF) fully-constrained CDPRs is used. The novelty of the design allows reducing the variation in the cable directions and forces increasing the robot WFW; nevertheless, it presents a low stiffness along the x direction. This paper presents the dynamic model of the novel proposal together with a new dynamic control technique, which rejects the vibrations caused by the stiffness loss while ensuring an accurate trajectory tracking. The simulation results show that the controlled system presents a larger WFW than the conventional scheme of the CDPR, maintaining a good performance in the trajectory tracking of the end-effector. The novel proposal presented here can be applied in multiple planar applications

Performance Evaluation of an Optoelectronic Oscillator Based on a Band-Pass Microwave Photonic Filter Architecture

The experimental performance evaluation of an optoelectronic oscillator based on a band-pass microwave photonic filter architecture is carried out. The novelty of this proposal resides in the fact that the architecture used allows enhancing the free spectral range of the optoelectronic oscillator. Considering the optical spectral characteristics of the multimode laser diode used as an optical source, the length and the chromatic dispersion parameter of the optical fiber which acts as a feedback loop, it is possible to determine the appearance of a series of spectrally pure microwave signals widely spaced. In particular, the experimental results show a phase noise as low as -92.69 dBc/Hz at 10 kHz offset frequency from the 2.26 GHz carrier for an optical delay line of 25.24 km and a Q factor of 2.04×109

Using a Participatory Research Process to Address Disproportionate Hispanic Cancer Burden

Community-based participatory research (CBPR) offers great potential for increasing the impact of research on reducing cancer health disparities. This article reports how the Community Outreach Core (COC) of the Meharry–Vanderbilt–Tennessee State University (TSU) Cancer Partnership has collaborated with community partners to develop and implement CBPR. The COC, Progreso Community Center, and Nashville Latino Health Coalition jointly developed and conducted the 2007 Hispanic Health in Nashville Survey as a participatory needs assessment to guide planning for subsequent CBPR projects and community health initiatives. Trained community and student interviewers surveyed 500 Hispanic adults in the Nashville area, using a convenience sampling method. In light of the survey results, NLHC decided to focus in the area of cancer on the primary prevention of cervical cancer. The survey led to a subsequent formative CBPR research project to develop an intervention, then to funding of a CBPR pilot intervention study to test the intervention

Study of secondary muons detected within the tunnels of the Cholula pyramid

The pyramid of Cholula was built at the beginning of 100 B.C. and during of period of 500 years it was finished, had several new constructions, based on the previous constructions. The primarily material of construction is the adobe. Early in 1931 archaeological excavations began with the intention of exploring the interior of the pyramid, excavations were stopped in 1971, and to date no further excavations have been carried out. This work shows the first measurements of muons, particles that are very penetrating, these are generated by primary cosmic rays that was incoming in the atmosphere and these generates a rain of secondary particles, among them the muons. To measure this kind of particles was implemented a detector system, it is formed by a scintillator plastic coupled to a tube photomultiplier; the signals were acquired by mean of an oscilloscope. The detector was collocated near of the center of the pyramid; the location belongs to the maxima concentration in mass over the detector. Graphs of the charge distribution, maximum amplitude and characteristic rise times of the generated pulses in a plastic scintillator are shown, this is scintillator was synthesized in the materials laboratory of the FCFM-BUAP. In addition the optical characterization of the same was realized
