Improving Instrumental Research Competencies in Master's Degree Students: Research Education Program as a Strategy for Training Productive Researchers

Purpose: The present study evaluated instrumental research competencies in master's degree students using the application of a research program as a strategy. Theoretical framework: It was based on the theoretical foundations on research and instrumental research competencies, as well as the types of scientific production, as ways of providing this knowledge to future researchers. Previous studies that addressed the relationship between the research education program and the training of researchers with research competencies were reviewed, identifying the key elements that contribute to the success of this strategy. Design/methodology/approach: A quantitative research with a quasi-experimental design was developed with the participation of 25 master's degree students with mention in university teaching from a public university in the Loreto region of Peru. Results and Discussion: A significant relationship was found between the research educational program and instrumental research competencies (p<0.005) in which the training of master's degree students in instrumental research competencies partially had this relationship. The results indicated that the master's degree students with mention in university teaching who were part of the study had better instrumental research competencies. Research, practical and social implications: It can be affirmed that research-based learning is important to improve scientific writing, since it allows for a better formation of competent researchers. Originality/value: This study contributes original value to the field of master's study by providing empirical evidence on the effectiveness of the research education program to improve instrumental research competencies in master's degree students in Peruvian universities.

Compact anisotropic stellar distribution with linear barotropic equation of state in energy–momentum trace coupling modification of general relativity

There are no known exact isotropic or anisotropic stellar models with an equation of state in energy–momentum trace-coupling (EMTC) modifications of general relativity — the simplest linear case of f(R,T) gravity. The difficulty lies in the intricate entanglement of the density and pressure functions that generate intractable governing equations when an equation of state is introduced. For example there is no interior Schwarzschild incompressible star analogue in the well studied f(R,T) theory. In Einstein’s theory it is straightforward to find anisotropic stellar models with a linear equation of state since the system is under-determined and there remains one more choice to nominate any of the variables. This is also true in EMTC theories however, the master field equation is more formidable. If interpreted as a linear second order equation, no viable solutions emerge by prescribing one of the gravitational potentials or by suppressing some terms in the spirit of Tolman (1939). Rewriting as a nonlinear first order equation and speculating on a power-law form of the temporally directed gravitational potential results in success in finding a physically viable compact star distribution. Specifically the model has monotonic decrease of both pressure and density and a surface of vanishing pressure exists. Several stability tests are imposed and the model performs according to expectations. The singularity at the stellar center may be cured by insertion of a regular core enveloped by our fluid model in a multi-layered star.

Chemical Mobilization-Based Capillary Isoelectric Focusing-Mass Spectrometry Using the nanoCEasy Interface for Pharmaceutical Protein Analysis.

Capillary isoelectric focusing (CIEF) coupled with electrospray ionization mass spectrometry (ESI-MS) is regarded as an outstanding approach for protein and proteoform analysis, combining a high-resolution separation technique and an enhanced detection technique. The few so-far developed CIEF-ESI-MS approaches exhibit limitations regarding sensitivity and separation performance. Here, we report a new generic methodology for CIEF-ESI-MS based on chemical mobilization, leading to highly efficient separation. This new integrated methodology relies on exchanging catholyte, initially introduced in the nanoCEasy interface in the focusing step, with sheath liquid (SL) in order to chemically mobilize the analytes into the ESI-MS system. The CIEF-MS method is evaluated by separation of a peptide set, model proteins, and monoclonal antibody charge variants. The effect of various parameters including master mixture composition, field strength, catholyte, SL composition, focusing time, and capillary conditions is optimized and discussed. Excellent separation performance can be achieved with a pI resolution down to 0.1 pH unit. The mobilization reproducibility is demonstrated with "migration time" RSDs below 10%. Additionally, the chemical mobilization is compared with the pressure assistance-chemical mobilization method, demonstrating that even a small pressure causes a strong decrease in separation performance, which clearly indicates the benefit of the chemical mobilization-based method. The applicability and separation power of the developed method are further exhibited by separation of Fc-conjugated insulins (mass = 62 kDa) differing in only one amino acid.

Exact evaluation of large-charge correlation functions in nonrelativistic conformal field theory

The large-charge master field which generates all n-point correlation functions with an insertion of large charge Q in nonrelativistic conformal field theory is obtained. This field is used to compute Schrödinger-invariant n-point correlation functions of large-charge operators via a direct evaluation of the path integral. Conformal dimensions are found to agree with calculations based on the state-operator correspondence. The master field solution exhibits an emergent harmonic trap whose frequency is a function of the Euclidean time. The large-charge effective action with operator insertions describes a droplet of superfluid matter whose spatial size scales with the time separation of sources. The solution is used to compute Schrödinger symmetry breaking corrections in the large-charge effective field theory (EFT) due to a finite scattering length in the fundamental theory of fermions near unitarity. The scaling of these effects in the large-charge power counting scheme is established, and the size of the effects is quantified using input from quantum Monte Carlo simulations of the near-unitary gas, as well as from the large-N expansion at large charge.

Gravito-magnetic polarization of Schwarzschild black hole

We determine the gravito-magnetic Love numbers of non-rotating black holes in all spacetime dimensions through a novel and direct derivation. The Ishibashi-Kodama master field and its associated field equation are avoided. The matching to the EFT variables is simple. This method allows us to correct the values in the literature. Moreover, we highlight a parity-based selection rule for nonlinear terms that include both electric-type and magnetic-type gravitational field tensors, enabling us to conclude that many of the nonlinear response coefficients in the Schwarzschild black hole effective action vanish.

Usability of Health Care Price Transparency Data in the United States: Mixed Methods Study.

Increasing health care expenditure in the United States has put policy makers under enormous pressure to find ways to curtail costs. Starting January 1, 2021, hospitals operating in the United States were mandated to publish transparent, accessible pricing information online about the items and services in a consumer-friendly format within comprehensive machine-readable files on their websites. The aims of this study are to analyze the available files on hospitals' websites, answering the question-is price transparency (PT) information as provided usable for patients or for machines?-and to provide a solution. We analyzed 39 main hospitals in Florida that have published machine-readable files on their website, including commercial carriers. We created an Excel (Microsoft) file that included those 39 hospitals along with the 4 most popular services-Current Procedural Terminology (CPT) 45380, 29827, and 70553 and Diagnosis-Related Group (DRG) 807-for the 4 most popular commercial carriers (Health Maintenance Organization [HMO] or Preferred Provider Organization [PPO] plans)-Aetna, Florida Blue, Cigna, and UnitedHealthcare. We conducted an A/B test using 67 MTurkers (randomly selected from US residents), investigating the level of awareness about PT legislation and the usability of available files. We also suggested format standardization, such as master field names using schema integration, to make machine-readable files consistent and usable for machines. The poor usability and inconsistent formats of the current PT information yielded no evidence of its usefulness for patients or its quality for machines. This indicates that the information does not meet the requirements for being consumer-friendly or machine readable as mandated by legislation. Based on the responses to the first part of the experiment (PT awareness), it was evident that participants need to be made aware of the PT legislation. However, they believe it is important to know the service price before receiving it. Based on the responses to the second part of the experiment (human usability of PT information), the average number of correct responses was not equal between the 2 groups, that is, the treatment group (mean 1.23, SD 1.30) found more correct answers than the control group (mean 2.76, SD 0.58; t65=6.46; P<.001; d=1.52). Consistent machine-readable files across all health systems facilitate the development of tools for estimating customer out-of-pocket costs, aligning with the PT rule's main objective-providing patients with valuable information and reducing health care expenditures.

Large N master field optimization: the quantum mechanics of two Yang-Mills coupled matrices

We study the large N dynamics of two massless Yang-Mills coupled matrix quantum mechanics, by minimization of a loop truncated Jevicki-Sakita effective collective field Hamiltonian. The loop space constraints are handled by the use of master variables. The method is successfully applied directly in the massless limit for a range of values of the Yang-Mills coupling constant, and the scaling behaviour of different physical quantities derived from their dimensions are obtained with a high level of precision. We consider both planar properties of the theory, such as the large N ground state energy and multi-matrix correlator expectation values, and also the spectrum of the theory. For the spectrum, we establish that the U(N) traced fundamental constituents remain massless and decoupled from other states, and that bound states develop well defined mass gaps, with the mass of the two degenerate lowest lying bound states being determined with a particularly high degree of accuracy. In order to confirm, numerically, the physical interpretation of the spectrum properties of the U(N) traced constituents, we add masses to the system and show that, indeed, the U(N) traced fundamental constituents retain their “bare masses”. For this system, we draw comparisons with planar results available in the literature.

Pole-skipping of gravitational waves in the backgrounds of four-dimensional massive black holes

Pole-skipping is a property of gravitational waves dictated by their behaviour at horizons of black holes. It stems from the inability to unambiguously impose ingoing boundary conditions at the horizon at an infinite discrete set of Fourier modes. The phenomenon has been best understood, when such a description exists, in terms of dual holographic (AdS/CFT) correlation functions that take the value of ‘0/0’ at these special points. In this work, we investigate details of pole-skipping purely from the point of view of classical gravity in 4d massive black hole geometries with flat, spherical and hyperbolic horizons, and with an arbitrary cosmological constant. We show that pole-skipping points naturally fall into two categories: the algebraically special points and a set of pole-skipping points that is common to the even and odd channels of perturbations. Our analysis utilises and generalises (to arbitrary maximally symmetric horizon topology and cosmological constant) the ‘integrable’ structure of the Darboux transformations, which relate the master field equations that describe the evolution of gravitational perturbations in the two channels. Finally, we provide new insights into a number of special cases: spherical black holes, asymptotically Anti-de Sitter black branes and pole-skipping at the cosmological horizon in de Sitter space.

Research on Cultivating International Talents in China's Agricultural Master's Program under the Context of International Education

China's higher education is gradually becoming more internationalized, particularly in the areas of international education and internationalization of graduate education. This trend provides important opportunities for the cultivation of high-quality international talents in the field of agriculture, particularly for the agricultural master's degree. In the process of talent cultivation, the characteristics of international talents in the field of agricultural master's degree continue to deepen. By analyzing the international talent education strategies of domestic and foreign universities, we have found that the cultivation of international talents in the field of agricultural master's degree in China needs to strengthen internationalization construction in four aspects: cultivation concepts, foreign language teaching, student training, and faculty development, in order to improve the quality of talent cultivation and enhance the international competitiveness of China's agriculture.

Quantum Holonomy Fields

We investigate lattice and continuous quantum gauge theories on the Euclidean plane with a structure group that is replaced by a H-algebra. H-algebras are non-commutative analogues of groups and contain the class of Voiculescu's dual groups. We are interested in non-commutative analogues of random gauge fields, which we describe through the random Holonomy that they induce. We propose a general definition of a Holonomy Field with symmetries displaying the structure of a H-algebra and construct such a field starting from a quantum Lévy process on a H-algebra in the category of probability spaces. We call them Quantum Holonomy Fields. We also consider the more abstract case of an H-algebra in a given algebraic category. This yields the notion of a Categorical Holonomy Field. As an application, we define higher dimensional generalizations of the so-called Master Field on the plane.

A mixed formulation of limit analysis for seismic slope stability

This paper presents a mixed formulation based on the node-based smoothed finite-element method for estimating seismic slope stability. The final form of Hellinger–Reissner is cast as the min–max optimisation problem with conic constraints. Solving the second-order cone programming directly determines both master fields, stress and displacement. It is shown from the numerical results that the stability numbers obtained are almost equal to the exact collapse loads for the relatively flat slopes. Moreover, the effects of the dilation angle on the seismic stability number are studied by incorporating a simple iterative technique in the algorithm cast as max-min programming, arriving at the observation that both the static and the seismic stability numbers are susceptible to the dilation angle. Although the magnitude of the seismic stability number largely depends on the vertical seismic acceleration for a broad range of typical slope angles, the seismic stability number for the relatively flat slopes in cohesive-frictional soils is likely independent of the seismic acceleration in the vertical direction.

Challenges of a professional master's student in Mathematics Education: what my experience allows me to say

Since its creation, the professional master's degree has allowed master's students to reflect on pedagogical practice in Mathematics. In this context, this article aims to analyze the challenges of a master's student of a professional program in composing her field intervention and the resonances of this for her professionalism. To this end, the methodology is supported by a narrative perspective, in which the significant points of the master's field process are described. As a result, it can be seen that the moment of planning and the moment of application are fundamental and striking in the constitution of professionalism in a context of professional master's, allowing significant spaces for reflection and production of the identity of a researcher in his own practice. With the study, the need for professional master's degrees to trigger discussions on the training of student-teachers who attend their courses is concluded.

Healthy lifestyles for male masters athletes from frailty and lifestyle points of view

Authors and collaborators have investigated the subjective health and life satisfaction of elderly male Masters’ athletes. Subjects were 97 cases with 63.9 years in average, who participated in Masters track and field competition event, and they are asked to answer the questionnaire concerning healthy lifestyle habits. It had the inquiries about subjective health, satisfaction of daily life, spending leisure time and others. Two groups were categorized as non-elderly and elderly people (n=46/51), and compared for the detail such as frailty. As a result, no significant difference was found between two age groups for several aspects including daily lifestyle situation.

Motives for competitive sports participation in masters track and field athletes: Impact of sociodemographic factors and competitive background.

Masters athletes due to their lifelong engagement in sport represent a unique group to study motivation for regular physical activity, but there is less scientific data on the sport motives in masters athletes. Therefore, the aim of this study was to evaluate the association of age, sex, education, nationality, competitive background and training amount with sport motives of masters track and field athletes. 811 (254 women) athletes aged 35-89 years participated in European Veterans Athletics Championships in the year of 2000. Sport motives were assessed with a questionnaire and categorized into1) well-being, 2) competitive and performance 3) health and fitness motives. Men considered health and fitness motives more important than women (p = 0.022). Over 65-year-old athletes considered health and fitness motives more important than the youngest, 35-49-year age group (p<0.001). Education was not associated with sport motives, while motives varied significantly among different nationalities. Athletes from Nordic Countries considered well-being motives more important than Southern Europeans (p<0.001) or Western Europeans (p<0.05). Athletes from Nordic Countries (p = 0.003), Eastern Europe (p<0.001) and Central Europe (p<0.001) found health and fitness motives more meaningful than athletes from the British Isles. Furthermore, athletes with competitive background before the age of 35 and training amount more than 7.5 h a week found competitive and performance motives more important than athletes without a competitive history (p = 0.002). These results suggest that age, sex, nationality and former athleticism are associated with sports motives among international level masters track and field athletes. It seems that while for masters athletes with competitive background performance motives dominate, for older adults, particularly for males, health and fitness motives are more important. In addition, when designing the exercise interventions for older adults, different sport motives across countries should be considered.

International cooperation as one of the directions for the development of the education system

One of the most important directions in the development of the system of secondary vocational education at the present stage is the need to constantly update the content and technologies of vocational education in accordance with current and future requirements for the qualifications of workers. Significant assistance in improving the quality of training of specialists can be provided by the development of international cooperation in the implementation of secondary vocational education programs. Establishing such cooperation will make it possible to take into account advanced foreign experience, increase the attractiveness of educational institutions of secondary vocational education among potential applicants, and bring programs of secondary vocational education to the international market of educational services.To date, international cooperation has received the greatest development in the fi eld of higher education, master’s and postgraduate programs.The experience of international cooperation of the Chelyabinsk Institute of Railways — a branch of the Ural State University of Railways is considered. Information is provided on the main areas of international cooperation, including the search for potential partners among foreign educational organizations, with the subsequent formalization of relationships within the framework of international cooperation agreements, as well as the experience of implementing events within the framework of signed agreements, including the organization of joint international events of educational, scientifi c and sports orientation, work to improve the professional competencies of the personnel potential of Chelyabinsk Institute of Railways — a branch of the Ural State University of Railways through the internships of teachers in educational institutions of the Republic of Kazakhstan.

Injuries in Masters Field Hockey Players Competing in the 2018 World Cup: Comparisons of Prevalence, Location, and Type by Age, Sex, and Field Hockey Experience

This study examined prevalence, body location, and type of injuries reported by Masters Field Hockey players competing in the 2018 Masters and Grand Masters Field Hockey World Cups. There were 465 participants (284 females and 181 males) from 21 countries, ranging in age from 35 to 76 years. Participants completed The Health and Well-being of Masters Field Hockey Athletes Survey, which included injury type and location. The lower leg was the most common injury location and muscle strain the most common type of injury. Significant differences were found between females and males in upper extremity injuries and contusions.

Metaplectic representation and ordering (in)dependence in Vasiliev’s higher spin gravity

We investigate the formulation of Vasiliev’s four-dimensional higher-spin gravity in operator form, without making reference to one specific ordering. More precisely, we make use of the one-to-one mapping between operators and symbols thereof for a family of ordering prescriptions that interpolate between and go beyond Weyl and normal orderings. This correspondence allows us to perturbatively integrate the Vasiliev system in operator form and in a variety of gauges. Expanding the master fields in inhomogenous symplectic group elements, and letting products be controlled only by the group, we specify a family of factorized gauges in which we are able to integrate the system to all orders, producing exact solutions, including but not restricted to ones presented previously in the literature; and then connect, at first order, to a family of rotated Vasiliev gauges in which the solutions can be represented in terms of Fronsdal fields. The gauge function responsible for the latter transformation is explicitly constructed at first order. The analysis of the system in various orderings is facilitated by an analytic continuation of Gaussian symbols, by means of which one can distinguish and connect the two branches of the metaplectic double cover and give a rationale to the properties of the inner Klein operators as Gaussian delta sequences defining analytic delta densities. As an application of some of the techniques here developed, we evaluate twistor space Wilson line observables on our exact solutions and show their independence from auxiliary constructs up to the few first subleading orders in perturbation theory.

The Different Dimensions of Quality Care Management

Health service organizations expect Manager Nurses to develop activities that foster the best quality results both in terms of assistance and in terms of management. To do so, managers have to master management skills in order to understand the activity carried out by the Manager Nurses in an archipelago with several islands. This is a descriptive, analytical and exploratory study of quantitative nature. The data collection instrument was an autofill questionnaire, which included a Perception Scale of the Work of the Manager Nurses. The academic qualifications of the nursing managers are as follows: postgraduate studies in specific areas other than management (15,9%); postgraduate studies in the field of management (36,5%) and master’s degree in different areas (17,5%). The results in the field of the skills of management of nursing care may be the ones that require a bigger investment in terms of training. Regarding the skills in the field of political intervention and advice, the results observed were below expectations. The need for specific training in the field of management is obvious; we were able to prove that most of the Manager Nurses do not have specific training in the field of management, which would allow them to perform the management tasks based on solid knowledge, thus improving the quality of their service.
