The impact of trade with China and India on Argentina's manufacturing employment

For many in Latin America, the increasing participation of China and India in international markets is seen as a looming shadow of two"mighty giants"on the region's manufacturing sector. Are they really mighty giants when it comes to their impact on manufacturing employment? The authors attempt to answer this question by estimating the effects of trade with China and India on Argentina's industrial employment. They use a dynamic econometric model and industry level data to estimate the effects of trade with China and India on the level of employment in Argentina's manufacturing sector. Results suggest that trade with China and India only had a small negative effect on industrial employment, even during the swift trade liberalization of the 1990s.Labor Markets,Free Trade,Economic Theory&Research,Water and Industry,Trade Policy

Implementation of an Individualized Onboarding and Training for Nurse Managers

Abstract BACKGROUND: The onboarding and training of nurse managers varies drastically in healthcare institutions across the US, even within the same organization. Though evidence-based studies have demonstrated that the onboarding and training process are related to employee engagement, retention, and to the achievement of positive departmental and institutional goals and outcomes, most healthcare organizations do not invest in providing an effective onboarding and training based on evidence models and frameworks. This project was conducted at a 345-bed tertiary teaching medical center in the Boston area to determine the need for instituting an effective evidence-based onboarding and training process for nurse managers. METHODS: A pre- and post-intervention survey was conducted among 14 clinical nurse managers hired in the last 3.5 years for various ambulatory clinics and inpatient wards to explore their onboarding and training experience at the medical center in their first 90 days. Multiple platforms were utilized as bases for the creation and implementation of the three interventions presented in this project, including the Johns’ Hopkins Nursing Evidence-Based Practice Model (JHNEBPM), the American Organization for Nursing Leadership (AONL), the American Association of Critical Care Nursing (AACN), the Frontline Nurse Leader Conceptual Framework (FNLF), along with the “Novice to Expert” theoretical framework by Nursing Theorist Patricia Benner. INTERVENTIONS: The 14 nurse managers were asked to complete a pre-interventions quantitative survey related to their onboarding and training process at the medical center (MC), and to their experience level as a NM. Each participant was then asked to attend a one-hour presentation and was introduced to three proposed interventions for the implementation of an individualized onboarding and training process for nurse managers. The interventions presented included the utilization of the AONL’s Nurse Manager Competency Questionnaire (NMCQ) with mentorship, the utilization of the AACN’s Fundamental Skills of Nursing Management (FSNM) online modules, and the creation of an onboarding and training checklist based on the AONL’s Nurse Manager Leadership Development Framework (NMLDF). Participants were also asked complete a qualitative survey about their perceived effectiveness of the three interventions on the onboarding and training of new nurse managers after their attendance to the presentation. RESULTS: The quantitative and qualitative survey responses from participants revealed that their experience level as a NM and as registered nurse did not make the onboarding and training process easier for those who were more experienced, whether they came from another institution or were promoted from within. Participants expressed that having a formal evidence-based training platform, including an individualized and structured mentorship process, would have facilitated in accelerating their onboarding and training, as well as the achievement of departmental and organizational goals. CONCLUSION: Instituting a formal and individualized onboarding and training process with mentorship for newly hired clinical nurse managers will assist in advancing their knowledge about the organization, and in the provision of necessary skills to complete tasks more efficiently. Having such a process will subsequently promote faster achievement of departmental and organizational goals, including staff engagement, employee retention, increased patient satisfaction and outcomes, as well as promote strategic alignment with the mission and vision of the medical center.

Relativistic quantum dynamics of scalar bosons under a full vector Coulomb interaction

The relativistic quantum dynamics of scalar bosons in the background of a full vector coupling (minimal plus nonminimal vector couplings) is explored in the context of the Duffin-Kemmer-Petiau formalism. The Coulomb phase shift is determined for a general mixing of couplings and it is shown that the space component of the nonminimal coupling is a {\it sine qua non} condition for the exact closed-form scattering amplitude. It follows that the Rutherford cross section vanishes in the absence of the time component of the minimal coupling. Bound-state solutions obtained from the poles of the partial scattering amplitude show that the time component of the minimal coupling plays an essential role. The bound-state solutions depend on the nonminimal coupling and the spectrum consists of particles or antiparticles depending on the sign of the time component of the minimal coupling without chance for pair production even in the presence of strong couplings. It is also shown that an accidental degeneracy appears for a particular mixing of couplings.Comment: 8 pages, 1 table. arXiv admin note: text overlap with arXiv:1403.603

Shoulder kinematics is not influenced by external load during elevation in the scapular plane

The current study aimed to compare the shoulder kinematics (3D scapular orientation, scapular angular displacement and scapulohumeral rhythm) of asymptomatic participants under unloaded and loaded conditions during unilateral shoulder elevation in the scapular plane. We used a repeated-measures design with a convenience sample. Eleven male participants with an age range of 21–28 years with no recent history of shoulder injury participated in the study. The participants performed isometric shoulder elevation from a neutral position to approximately 150 degrees of elevation in the scapular plane in intervals of approximately 30 degrees during unloaded and loaded conditions. Shoulder kinematic data were obtained with videogrammetry. During shoulder elevation, the scapula rotated upwardly and externally, and tilted posteriorly. The addition of an external load did not affect 3D scapular orientation, scapular angular displacement, or scapulohumeral rhythm throughout shoulder elevation (P > .05). In clinical practice, clinicians should expect to observe upward and external rotation and posterior tilt of the scapula during their assessments of shoulder elevation. Such behavior was not influenced by an external load normalized to 5% of body weight when performed in an asymptomatic population

Understanding the role of hemodynamics in the initiation, progression, rupture, and treatment outcome of cerebral aneurysm from medical iamge-based computational studies

About a decade ago, the first image-based computational hemodynamic studies of cerebral aneurysms were presented. Their potential for clinical applications was the results of a right combination of medical image processing, vascular reconstruction, and grid generation techniques used to reconstruct personalziaed domains for computational fluid and solid dynamics solvers and data analysis and visualization techniques. A considerable number of studies have captivated the attention of clinicians, neurosurgeons, and neuroradiologists, who realized the ability of those tools to help in understanding the role played by hemodynamics in the natural history and management of intracranial aneurysms. This paper intends to summarize the most relevant results in the filed reported during the last years.Fil: Castro, Marcelo Adrian. Universidad Tecnológica Nacional.

Event horizons, gravitational waves and astrophysical kicks in black-hole spacetimes

In this thesis we use computational techniques (numerical simulations) to study different stages of black hole mergers. A first project describes topological properties of the main performer of this play, the black hole and its event horizon. We investigate three configurations: a continuum ring singularity, a \u27discretized\u27 ring (black holes arranged on a ring), and a linear distribution of black holes. We evolve each of the corresponding spacetimes forward and then backwards in time, searching for the respective event horizons. We find some evidence, based on configurations of multiple BHs arranged in a ring, that this configuration leads to singular limit where the horizon width has zero size, possibly indicating the presence of a naked singularity, when the radius of the ring is sufficiently large. In a second project, we study the dynamics of a hydrodynamical accretion disk around a recoiling black hole, which models the behavior of an accretion disk around a binary just after the merger, using \u27smoothed-particle hydrodynamics\u27 techniques. We simulated different recoil angles between the accretion disk and the recoil velocity of the black hole. We find that for more vertical kicks (angles \u3c 30 degrees) a gap remains present in the inner disk, while for more oblique kicks (angles \u3e 45 degrees), matter rapidly accretes toward the black hole. There is a systematic trend for higher potential luminosities for more oblique kick angles for a given black hole mass, disk mass and kick velocity, and we find large amplitude oscillations in time in the case of a kick oriented 60 degrees from the vertical
