Published: March 2022

A well-developed banking system is prerequisite for a fast-growing economy. The introduction of financial instruments is a collaborative effort that pits the results of analysis of the banking sector's development and impact on the economy against basic regulatory standards and approaches to state regulation of the financial system's development and banking subsystem. Banking sectors, according to economic literature, play an intermediation role by enabling money transfers between fund-suppliers and fund-demanders. This can be accomplished by attracting savings and then directing those funds into loans to fund various economic activities, resulting in economic growth (EG). Every bank has its own internal component that affects financial performance in a particular way the more efficient a country's financial sector develops, the more likely its limited resources will be channeled to the most productive use. Openness in the banking sector may have a direct impact on growth by enhancing access to financial services and indirectly by improving the efficiency of financial intermediaries, both of which lower the cost of financing and, as a result, encourage capital accumulation and economic growth. A variety of macroeconomic links, notably the one between financial development and long-run growth, have been studied using cross-country regressions. Microeconomic explanation differs from the traditional perspective, which sees financial intermediaries as a bridge between borrowers and lenders' differing interests in terms of the size, maturity, and risk of a financial investment.

Published: March 2022

Tomatoes consumed in Gombe are contaminated with traces and heavy metals due to accumulation of these metals in soil that absorbed by crop plants, which is the most serious environmental problem with significant implications on human health. This study focused on the comparative studies on concentrations of carcinogenic and non- carcinogenic heavy metals analyzed based on WHO Permissible limits. Sample T1 Tomatoes showed mean concentrations in decreasing order of Zn = 0.094 ± 0.045 mg/kg followed by Mn = 0.0744 ± 0.0031 mg/kg then Ni = 0.0394 ± 0.0014 mg/kg, Fe = 0.0163 ± 0.00113 mg/kg, Cd = 0.0063 ± 0.00106 mg/kg, Pb = 0.0031 ± 0.0062 mg/kg, Co = 0.00152 ± 0.00126 mg/kg, As = 0 respectively. Sample T2 showed mean concentrations of heavy metals with the highest of Ni = 0.2095 ± 0.27 mg/kg followed by Zn = 0.1761 ± 0.134 mg/kg, Mn = 0.0487 ± 0.0023 mg/kg, Fe = 0.0233 ± 0.00195 mg/kg, Cd = 0.0147 ± mg/kg, Pb = 0.0047 ± 0.0062 mg/kg, Co = 0.0075 ± 0.0065 mg/kg respectively with few above WHO limits of 0.002 – 0.005mg/kg. Sample T3 Tomatoes showed mean concentrations with highest in decreasing order of Mn = 0.0829 ± 0.017 mg/kg followed by Ni = 0.0809 ± 0.00412 mg/kg, Zn = 0.0504 ± 0.0031 mg/kg, Co = 0.0225 ±0.00080 mg/kg, Cd = 0.0179 ± 0.00243 mg/kg, Fe = 0.0143 ± 0.00057 mg/kg. As = 0.0011 ± 0.000265 mg/kg, Pb = 0.0004 ± 0.000058 mg/kg respectively. Hazard Index (HI) of non-carcinogenic Heavy metals analyzed in Tomatoes samples showed highest hazard index in all the three pathways with Co = 3.64 E+ 00 followed by Pb = 2.71E+00 then Cd = 5.51E-01, Ni = 1.07E-02, Mn = 6.81E-03, As = 2.16E-03, Zn = 7.79E-04, while the lowest Hazard index was shown by Fe = 5.62E-05 indicating HI > 1 with adverse health risk in decreasing order of Co > Pb > Cd > Ni > Mn > As > Zn > Fe respectively. Cancer risk effects of carcinogenic heavy metals investigated through ingestion showed the highest cancer risk of Cd = 4.10E-05 followed by As = 3.23E-07 then Pb = 7.14E-06 with order of Cd > As > Pb > Co while cancer risk through inhalation showed the highest in Co = 1.27E-11 followed by Cd = 7.06E-12 then As = 4.76E-13, the lowest of Pb = 4.41E-14 with order of Co > Cd > As > Pb indicating that some heavy metals contaminated the tomatoes analyzed were projecting while hazard and cancer risk on human health will persisted on body systems at certain prolong time, examining of these heavy metals levels will safeguard public health.

This is very unfortunate that even in 21st century most of us are still unaware of the fact that the microbial origin of cancer exists in nature. And, this is all due to the lack of knowledge about their potentialities in causing cancer in human and animals. Further, as in recent past, some of these viruses having high rate of mutabilities and adaptabilities have already been proven their abilities to transform the host cells dividing indefinitely. The present review discusses some of the oncogenic viruses developing human cancers including their mechanisms of cancer development known so far in the same field.

Published: March 2022

Piper guineense (uziza) leaves may have therapeutic input on male infertility caused by Lead exposure. This study investigated the antioxidant activities of the ethanolic extract of Piper guineense leaves (EEPL) on lead-induced testicular toxicity in rats. Twenty male wistar rats (150-200g) were divided into 4 groups consisting of 5 rats each. Control received 1ml of distilled water, lead only received 150mg/kg of lead, low dose received 150mg/kg of lead + 300mg/kg of EEPL, high dose received 150mg/kg of lead + 600mg/kg of EEPL. Administration was done orally for 14 days and then sacrificed. Blood was collected and analysed for serum testosterone and testes were harvested and homogenised for testicular antioxidant enzymes and zinc levels. Data was analysed for ANOVA using Graph Pad Prism 5. Lead exposure negatively affected the antioxidant enzymes, testosterone and zinc levels. Administration of EEPL significantly (p<0.05) increased the testosterone and zinc levels in a dose dependent manner. EEPL also significantly (p<0.05) increased the testicular Superoxide dismutase, Catalase, and Glutathione peroxidase levels and significantly decreased the testicular Malondialdehyde levels. Piper guineense leaves ameliorate testicular oxidative stress damage induced by lead toxicity.

Authors: Casal Oubiña Daniel
Published: March 2022

O fundamento da transformación do traballo parlamentario moderno explícase pola importancia dos partidos e a extensión das políticas redistributivas, cuxa principal consecuencia é o desprazamento do lexislativo a favor do executivo. Este artigo analiza se o desenvolvemento das asembleas lexislativas nas comunidades autónomas reforzou as cifras de control escrito. Para iso, o artigo analiza a función de control parlamentario, constrúe unha base de datos sobre os mecanismos de control escrito existentes nos 17 parlamentos autonómicos (preguntas escritas e solicitudes de informes) e propón unha modelización dos mecanismos de control escrito en función do seu posicionamento cara ao poder executivo (modelo racional) ou cara ao parlamento (modelo fiscalizador).

Finalización del estado de alarma: la desorganización jurídico-administrativa continúa
Authors: Fernández de Gatta Sánchez Dionisio
Published: March 2022

La pandemia del COVID-19 provocó en España la declaración de tres estados de alarma , con problemas jurídicos; los cuales se han agudizado con la finalización del último, ya que el Gobierno de la Nación se ha desentendido de la gestión de la epidemia, responsabilizando a las Comunidades Autónomas de la misma, en un proceso mal llamado de “cogobernanza”, con más problemas aún. Por otra parte, se han dado al Tribunal Supremo unos poderes cuasi-normativos y administrativos. Finalmente, el Tribunal Constitucional ha declarado inconstitucionales los estados de alarma declarados, y el cierre del Congreso de los Diputados. Y todo ello sin tener una legislación apropiada para luchar contra el COVID-19, en pleno ascenso de la sexta ola de la epidemia.

Article describes a method for increasing reliability of an automated control system ship repair production in event of prompt occurrence of deviations during production process caused by various external and internal factors using digital twins. Object of the research is an automated control system for digital twins at an enterprise small-scale and single-order production. To improve reliability of system under critical load conditions of individual shops and sections, it proposed to automate operational management. Modernization of system consists in providing feedback with automatic correction of information state of control core. The core of management is an information base that exists in a quasi-metric two-dimensional space with coordinates of set workplaces of enterprise and actual current time. Thus, it becomes possible to directly influence constantly changing state of nucleus. For this, controlled access to change digital twin is organized in accordance with real state of production process. When a new order is placed or deviations occur during the production process, state of control core is adjusted. It consists in finding and placing unfulfilled technological operations in workload schedule. To implement production management based on digital twins, it is proposed to reorganize functions and relationships of performers, as well as to create an appropriate infrastructure.

Значительный объем морских перевозок наливных грузов создал проблему переноса опасных и патогенных водных организмов с судовым водяным балластом. В настоящее время для ее решения применяются различные технологические операции. Наиболее распространенной является процедура замены балласта. Дополнительно, для повышения эффективности данной операции танкеры стали оборудоваться системами промывки балластных танков. Для разработки системы автоматического управления такой системой необходимо соответствующее алгоритмическое обеспечение. В работе представлен алгоритм управления процессом промывки танка изолированного балласта, являющегося частью алгоритма управления балластными операциями. Он предусматривает подготовительные процедуры, синхронный и асинхронный режим работы промывочных сопел, процедуры окончания промывки. При синхронном режиме все сопла работают одновременно, независимо от уровня жидкости. При асинхронном режиме группы промывочных сопел включаются и отключаются в зависимости от уровня в балластном танке. Рассматриваемый алгоритм может быть использован при разработке программного обеспечения системы управления балластной системой танкера.

A significant volume of sea transportation of liquid cargoes has created the problem of transferring dangerous and pathogenic aquatic organisms with ship's ballast water. Currently, various technological operations are used to solve it. The most common is the ballast replacement procedure. Additionally, to increase the efficiency of this operation, tankers are equipped with ballast tank flushing systems. To develop an automatic control system for these systems, appropriate algorithmic support is needed. The paper presents an algorithm for controlling the process of washing an isolated ballast tank flushing, which is part of the ballast operations control algorithm. It provides for preparatory procedures, synchronous and asynchronous operation of the flushing nozzles, and flushing finish procedures. In synchronous mode, all nozzles work simultaneously, regardless of the liquid level. In asynchronous mode, groups of flushing nozzles are switched on and off depending on the level in the ballast tank. The algorithm under consideration can be used in the development of software for the control system of the tanker ballast system.
14 pont a közbeszerzési eljárások felgyorsítására, avagy miért készítenek jó tervezők rossz terveket?

claroscuros del “non bis in idem” en el espacio jurídico europeo
Authors: Cano Campos Tomás
Published: March 2022

El presente trabajo destaca la amenaza de duplicidad punitiva en el espacio jurídico europeo y las dificultades para encontrar un criterio claro y pacífico que sirva para determinar el alcance y contenido del principio non bis in idem. Tras poner de manifiesto su reconocimiento normativo y los diferentes estándares de protección en los textos europeos y en el Derecho interno español, se analiza críticamente la jurisprudencia del TEDH y del TJUE, que se caracteriza no sólo por su casuismo y fragmentación, sino también por una errónea ampliación de la definición del elemento idem que está conduciendo a una peligrosa relativización del otro elemento de la prohibición: el bis. El estudio concluye con una sintética referencia al fundamento del non bis in idem, en el que subyacen algunos de los equívocos que han provocado esa situación.
Is theology more of a field than a father is a king? Modelling semantic relatedness in processing literal and metaphorical statements
Authors: Westbury Chris , Harati Parastoo
Published: March 2022

One major question in the study of metaphors historically is: Are different mechanisms involved in the comprehension of figurative statements versus literal statements? Many studies have addressed this question from a variety of perspectives, with mixed results. Following Harati, Westbury, and Kiaee (Behavior Research Methods, 53, 2214-2225, 2021), we use a computational (word embedding) model of semantics to approach the question in a way that allows for the quantification of the semantic relationship between the two keywords in literal and metaphorical “x is a y” statements. We first demonstrate that almost all literal statements (95.2% of 582 statements we considered) have very high relatedness values. We then show that literality decisions are slower for literal statements with low relatedness and metaphorical statements with high relatedness. We find a similar but smaller effect attributable to the cosine of the vectors representing the two keywords. The fact that the same measurable characteristics allow us to predict which metaphors or literal sentences will have the slowest literality decision times suggests that the same processes underlie the comprehension of both literal and metaphorical statements.

Published: March 2022

Metal-organic framework (MOF) membranes are potentially useful in gas separation applications. Conventional methods of MOF membrane preparation require multiple steps and high-pressure conditions. In this study, a reliable one-step interfacial synthesis method under atmospheric pressure has been developed to prepare zeolitic imidazolate framework-8 (ZIF-8) membranes supported on porous α-Al2O3 disks. To obtain optimal ZIF-8 membranes, three reaction parameters were investigated, namely, reaction temperature, reaction time, and concentration of the organic linker (i.e., 2-methylimidazole). The growth of ZIF-8 membranes under various parameters was evaluated by field-emission scanning electron microscopy, and the optimal synthesis conditions were determined (i.e., 80 °C for 12 h in 50 mM of 2-methylimidazole). The as-synthesized ZIF-8 membranes were then applied to CO2/N2 gas separation, which exhibited a maximum separation factor of 5.49 and CO2 gas permeance of 0.47 × 10−7 mol·m−2·s−1·Pa−1.

The author focuses on the differences in economic systems between countries with balanced and sustainable industrial systems and countries with fragile systems in his study. These differences are under analysis from the perspective of assessment: planning system, wants, globalization, the COVID-19 pandemic and the related crisis. Lastly, the author concludes that countries that have not made the transition to advanced systems of financial relations have been the most successful in maintaining the viability of their economies against the backdrop of a global pandemic.
The evolution of state paternalism and noonomy
Authors:   Institute of Economics of the Russian Academy of Sciences, Voeykov M.I.
Published: March 2022

Evolution of the economic functions of the state in the conditions of nonomics. The article examines the problems of the economic role of the state in modern society. It shows the failure of the liberal economic model and minimization of the role of the state. Modern production saturated with new technologies and scientific knowledge requires completely new regulators in comparison with the market ones. A new economy is developing, which in scientific literature is called noonomics. Many elements of the market economy are fading away in it, such as private property, money, finance, free competition, which acquire a new quality. A new problematic field for political economy is emerging.

Published: March 2022

The authors formulate and substantiate the hypothesis on sequential dissemination of base-level technologies in such segments as communications, production and transportation. This conceptual approach explains retroactive dynamics of the global economic system and the current situation in the world economy. The article establishes the cyclic repetition of basic technologies of technological modes and of relevant regimes that regulate global economic relations. The authors forecast which sectors will serve as global economic drivers and what foreign economic policies will be pursued by global leaders in the next fifty years. The article substantiates objective ontological causality behind the formation of industrial and new industrial society theories.

Published: March 2022

The dispersion measure of fast radio bursts (FRBs) encodes the integrated electron density along the line of sight, which is typically dominated by the intergalactic medium contribution in the case of extragalactic FRBs. In this paper, we show that incorporating wide-field spectroscopic galaxy survey data in the foreground of localized FRBs can significantly improve constraints on the partition of diffuse cosmic baryons. Using mock dispersion measures and realistic light-cone galaxy catalogs derived from the Millennium simulation, we define spectroscopic surveys that can be carried out with 4 and 8 m class wide-field spectroscopic facilities. On these simulated surveys, we carry out Bayesian density reconstructions in order to estimate the foreground matter density field. In comparison with the “true” matter density field, we show that these can help reduce the uncertainties in the foreground structures by ∼2–3× compared to cosmic variance. We calculate the Fisher matrix to forecast that N = 30 (96) localized FRBs should be able to constrain the diffuse cosmic baryon fraction to ∼10% (∼5%) and parameters governing the size and baryon fraction of galaxy circumgalactic halos to within ∼20%–25% (∼8%–12%). From the Fisher analysis, we show that the foreground data increase the sensitivity of localized FRBs toward our parameters of interest by ∼25×. We briefly introduce FLIMFLAM, an ongoing galaxy redshift survey that aims to obtain foreground data on ∼30 localized FRB fields.
Constructing the Emission-line Galaxy–Host Halo Connection through Auto and Cross Correlations
Authors: Gao Hongyu , Jing Y. P. , Zheng Yun , Xu Kun
Published: March 2022

We investigate the [O ii] emission-line galaxy (ELG)-host halo connection via auto and cross correlations, and propose a concise and effective method to populate ELGs in dark matter halos without assuming a parameterized halo occupation distribution (HOD) model. Using the observational data from VIMOS Public Extragalactic Redshift Survey, we measure the auto and cross correlation functions between ELGs selected by [O ii] luminosity and normal galaxies selected by stellar mass. Combining the stellar–halo mass relation derived for the normal galaxies and the fraction of ELGs observed in the normal galaxy population, we demonstrate that we can establish an accurate ELG–halo connection. With the ELG–halo connection, we can accurately reproduce the auto and cross correlation functions of ELGs and normal galaxies both in real space and in redshift space, once the satellite fraction is properly reduced. Our method provides a novel strategy to generate ELG mock catalogs for ongoing and upcoming galaxy redshift surveys. We also provide a simple description for the HOD of ELGs.

Published: March 2022

This work presents a new physically motivated supervised machine-learning method, hydro-bam, to reproduce the three-dimensional Lyα forest field in real and redshift space, which learns from a reference hydrodynamic simulation and thereby saves about seven orders of magnitude in computing time. We show that our method is accurate up to k ∼ 1 h Mpc−1 in the one- (probability distribution function), two- (power spectra), and three-point (bispectra) statistics of the reconstructed fields. When compared to the reference simulation including redshift-space distortions, our method achieves deviations of ≲2% up to k = 0.6 h Mpc−1 in the monopole and ≲5% up to k = 0.9 h Mpc−1 in the quadrupole. The bispectrum is well reproduced for triangle configurations with sides up to k = 0.8 h Mpc−1. In contrast, the commonly adopted Fluctuating Gunn–Peterson approximation shows significant deviations, already when peculiar motions are not included (real space) at configurations with sides of k = 0.2–0.4 h Mpc−1 in the bispectrum and is also significantly less accurate in the power spectrum (within 5% up to k = 0.7 h Mpc−1). We conclude that an accurate analysis of the Lyα forest requires considering the complex baryonic thermodynamical large-scale structure relations. Our hierarchical domain-specific machine-learning method can efficiently exploit this and is ready to generate accurate Lyα forest mock catalogs covering the large volumes required by surveys such as DESI and WEAVE.

Published: March 2022

The shape of the ambient circumnuclear medium (ACM) density profile can probe the history of accretion onto the central supermassive black holes in galaxies and the circumnuclear environment. However, due to the limitations of instrument resolution, the density profiles of the ACM for most galaxies remain largely unknown. In this work, we propose a novel method to measure the ACM density profile of active galactic nuclei (AGNs) by the equilibrium between the radiation pressure on the warm absorbers (WAs, a type of AGN outflow) and the drag pressure from the ACM. We study the correlation between the outflow velocity and ionization parameter of WAs in each of the five Seyfert 1 galaxies (NGC 3227, NGC 3783, NGC 4051, NGC 4593, and NGC 5548), inferring that the density profile of the ACM is between n ∝ r
−1.7 and n ∝ r
−2.15 (n is number density and r is distance) from 0.01 pc to parsec scales in these five AGNs. Our results indicate that the ACM density profile in Seyfert 1 galaxies is steeper than the prediction by the spherically symmetric Bondi accretion model and the simulated results of the hot accretion flow, but more in line with the prediction by the standard thin-disk model.
Model-independent Reconstruction of the Cosmological Scale Factor as a Function of Lookback Time
Authors: Zhang Jian-Chen , Zheng Jing , Zhang Tong-Jie
Published: March 2022

We present a model-independent method of reconstructing scale factor against lookback time from the Observational Hubble parameter Data (OHD). The reconstruction method is independent of dynamical models and is only based on the Friedmann–Robertson–Walker metric. We also calculate the propagation of error in the reconstruction process. The reconstruction data errors mainly come from trapezoidal rule approximation and the uncertainty from OHD. Furthermore, the model discrimination ability of original OHD and reconstructed a–t data is discussed under a dimensionless standard method. The a–t data can present the differences between cosmology models more clearly than H–z data by comparing their coefficients of variations. Finally, we add 50 simulated H(z) data to estimate the influence of future observation. More Hubble measurements in the future will help constrain cosmological parameters more accurately.

Published: March 2022

The formation of the interstellar complex organic molecules (iCOMs) is a hot topic in astrochemistry. One of the main paradigms trying to reproduce the observations postulates that iCOMs are formed on the ice mantles covering the interstellar dust grains as a result of radical–radical coupling reactions. We investigate iCOM formation on the icy surfaces by means of computational quantum mechanical methods. In particular, we study the coupling and direct hydrogen abstraction reactions involving the CH3 + X systems (X = NH2, CH3, HCO, CH3O, CH2OH) and HCO + Y (Y = HCO, CH3O, CH2OH), plus the CH2OH + CH2OH and CH3O + CH3O systems. We computed the activation energy barriers of these reactions, as well as the binding energies of all the studied radicals, by means of density functional theory calculations on two ice water models, made of 33 and 18 water molecules. Then, we estimated the efficiency of each reaction using the reaction activation, desorption, and diffusion energies and derived kinetics with the Eyring equations. We find that radical–radical chemistry on surfaces is not as straightforward as usually assumed. In some cases, direct H-abstraction reactions can compete with radical–radical couplings, while in others they may contain large activation energies. Specifically, we found that (i) ethane, methylamine, and ethylene glycol are the only possible products of the relevant radical–radical reactions; (ii) glyoxal, methyl formate, glycolaldehyde, formamide, dimethyl ether, and ethanol formation is likely in competition with the respective H-abstraction products; and (iii) acetaldehyde and dimethyl peroxide do not seem to be likely grain-surface products.

Published: March 2022

We study the magnetic field to density (B–ρ) relation in turbulent molecular clouds with dynamically important magnetic fields using nonideal three-dimensional magnetohydrodynamic simulations. Our simulations show that there is a distinguishable break density ρ
T between the relatively flat low-density regime and a power-law regime at higher densities. We present an analytic theory for ρ
T based on the interplay of the magnetic field, turbulence, and gravity. The break density ρ
T scales with the strength of the initial Alfvén Mach number

Simulation and Models of Onboard Secondary Power Sources for Aero and Space Devices
Authors: Gramatikov Pavlin
Published: March 2022

This article discusses the design and evaluation of secondary power sources using simulation models. In a set of circuit experiments, the models allow various parameters to be measured and visualized and aid in the analysis of the results. The models were developed using "NI MultiSim" (for simulation experiments); "Micro-Cap" (for functional experiments) and "LTspise" (for process control). Simulation helps to understand the basic concepts, analysis and tuning of circuit processes and parameters of secondary power supplies.

Emerging Infectious Diseases at the Beginning of the 21st Century
Authors: Lashley Felissa
Published: March 2022

The emergence and re-emergence of infectious diseases involves many interrelated factors. Global interconnectedness continues to increase with international travel and trade; economic, political, and cultural interactions; and human-to-human and animal-to-human interactions. These interactions include the accidental and deliberate sharing of microbial agents and antimicrobial resistance and allow the emergence of new and unrecognized microbial disease agents. As the 21st century begins, already new agents have been identified, and new outbreaks have occurred. Solutions to limiting the spread of emerging infectious diseases will require cooperative efforts among many disciplines and entities worldwide. This article defines emerging infectious diseases, summarizes historical background, and discusses factors that contribute to emergence. Seven agents that have made a significant appearance, particularly in the 21st century, are reviewed, including: Ebola and Marburg hemorrhagic fevers, human monkeypox, bovine spongiform encephalopathy, severe acute respiratory syndrome (SARS), West Nile virus, and avian influenza. The article provides for each agent a brief historical background, case descriptions, and health care implications.
Early Detection and Surveillance for Biopreparedness and Emerging Infectious Diseases
Authors: Veenema Tener , Tõke Joanna
Published: March 2022

Biological weapons and emerging infectious diseases pose a significant risk to public health. A timely response is needed to effectively treat and contain a potential infectious disease outbreak. Detection and surveillance of biological agents needs to be sensitive and specific to allow providers to quickly and accurately identify the disease process and begin the necessary response procedures. This article addresses the importance of early detection and surveillance of both intentional and unintentional biological events. Challenges of bioterrorism and the nursing role in response are discussed. Epidemiological considerations, such as route of transmission and personal protective equipment, are presented. An overview of the major surveillance systems, including advances in computer-based technology, is provided to help health care providers become aware of current surveillance systems and clinical decision support tools designed to help diminish the impact of biological threats.
Reflections on the DNP and an Alternate Practice Doctorate Model: The Drexel DrNP
Authors: Dreher H. Michael , Donnelly Gloria , Naremore Rita
Published: March 2022

In October 2004 the American Association of Colleges of Nursing (AACN) membership voted to require the Doctor of Nursing Practice (DNP) as the entry level degree for all new advanced practice nurses by 2015. At the time of the October 2004 vote there was only one DNP Program in the country, but the AACN proceeded to align itself with this one degree model. Was this vote for the 2015 mandate hasty or perhaps bold? Was the DNP model so singly endorsed, embraced prematurely? This article discusses the broader context of why the DNP should not be the only practice doctorate degree model offered and why the clinical research Doctor of Nursing Practice (DrNP) degree at Drexel University should be a viable alternative. In development since 2000, the Drexel Model DrNP is a hybrid degree combining the professional practice doctorate and the academic research doctorate. Unlike the DNP, it includes a clinical dissertation that will prepare a ‘practitioner/researcher’ to help advance the evidence base of nursing.
Kibbutz Nursing: An Exemplar of Primary Health Care
Authors: Ben-Sefer Ellen
Published: March 2022

Kibbutz nursing has long been established as a role that addresses the needs of a community’s health that arises from the underlying philosophy of the kibbutz communal structure. Despite the number of years of this nursing practice, there is a paucity of literature concerning its development and scope. While parallels may exist with other rural and remote nursing services throughout the world, the kibbutz philosophy of "each according to his ability and to each according to his needs" has governed the important areas of education, labor, and the provision of health to its members. This model of nursing care illustrates a number of examples of primary health principles that can be adapted and applied in other rural nursing practices. The article discusses problems nurses face in such an intimate setting as the kibbutz.
A Proposed Model for Military Disaster Nursing
Authors: Wynd Christine
Published: March 2022

There is a dearth of literature examining models related to nursing disaster preparedness and response, particularly in military nursing. Several recent articles address lessons learned by nurses who worked through wars and disasters, and these experiences can be used as a basis for a proposed model of military disaster nursing. This article will (a) review the literature about disaster nursing, including general disaster responses by nurses, disaster responses in military nursing, and research about military nurses and disaster response, (b) describe the uniqueness of the military environment, and (c) propose a model for military disaster nursing that can be evaluated for future implementation. Research about individual nurse readiness for deployment during disasters is also incorporated into the proposed model. Future research is needed to test the model and examine its relevance to military, as well as civilian, nursing for future disasters.
Culturally Competent Nursing Care for Families: Listening to the Voices of Mexican-American Women
Authors: Eggenberger Sandra , Grassley Jane , Restrepo Elizabeth
Published: March 2022

Mexican-Americans represent the fastest-growing minority population group in the United States. Gaining a cultural perspective of health care in the Mexican-American population necessitates listening to the voices of women because they assume primary responsibility for maintaining family health. The Transcultural Assessment Model developed by Giger and Davidhizar (2004) provides the framework for this exploration of Mexican-American women’s health care views. From this model the investigators developed an interview guide based on social organization and environmental control. Thematic analysis of interviews with six Mexican-American women revealed the importance of the family, religion, and locus-of-control in the health beliefs, attitudes, and lifestyle practices of this culture. Using the voices of Mexican-American women the investigators seek to promote an understanding of the culture as a guide for nursing care. The purpose of this article is to increase awareness of the Mexican-American cultural phenomena of social organization and environmental control which can guide the nurse to provide culturally competent care that meets the needs of Mexican-American women and their families.
Historical, Cultural, and Contemporary Influences on the Status of Women in Nursing in Saudi Arabia
Authors: Miller-Rosser Kolleen , Chapman Ysanne , Francis Karen
Published: March 2022

Global nursing shortages have necessitated closer scrutiny of recruitment and retention initiatives of nurses both locally and internationally. For many decades the nursing workforce of Saudi Arabia has relied on international expatriates to be the backbone of the industry. In recent years however, Saudi women have been recruited into nursing preparation courses conducted at degree level. The many twists and turns of providing a local Saudi Arabian nursing workforce has paralleled Saudi's own history and this paper follows that journey. Our research has enabled us to provide some insights into nursing pre and post the enlightenment that accompanied the Prophet Mohammed's influence. We emphasize the influences of women leaders who emerged in Mohammed's time and bring lasting authority to the development of nursing in Saudi Arabia. The cultural issues that bind women in this society are explicated and related to recruitment and retention issues in nursing. Education matters, both past and present, are highlighted emphasizing the gains that nursing as a distinct occupation has made. Finally the paper concludes with a summation of contemporary achievements in Saudi Arabia moving nursing towards the much needed professional status and parity with other careers in health care.
L’attachement tout au long de la vie
Authors: Miljkovitch Raphaële
Published: March 2022

L’article présente un tour d’horizon des connaissances sur l’attachement au cours de la vie. Est abordée la question de ce qui se joue dans la petite enfance par rapport au développement ultérieur. Bien que l’attachement se manifeste et s’évalue de manière différente selon l’âge et le type de relation (notamment dans les relations amoureuses et dans les relations filiales), une certaine continuité peut s’observer. Celle-ci est toutefois relative et fortement influencée par des facteurs contextuels.
L’approche piklérienne au regard de la néoténie
Authors: Golse Bernard
Published: March 2022

Après un petit rappel sur l’histoire de la pédagogie piklérienne et de l’Institut Pikler-Lóczy à Budapest, l’auteur montre comment l’approche piklérienne constitue une sorte de pari au regard de la néoténie humaine puisqu’il s’agit au fond de tenter de laisser toute sa part active au bébé (aussi petite, restreinte soit-elle) en dépit de son immaturité fondamentale et donc fondatrice. Il montre ensuite comment les positions de la psychanalyste Maria Torok sont compatibles avec le « concept d’activité autonome » qui fait partie des fondamentaux piklériens comme fruit de la « liberté motrice ». La dernière partie de l’article est consacrée aux liens qui peuvent être faits entre certains aspects de l’approche piklérienne (tel le concept de « personne de référence ») et la théorie de l’attachement.
