Development of clinical judgment model to guide nursing interns
Authors: Ibrahim Azza Fathi , Aly Azza Anwar 
Published: April 2018

Every day and every moment, nurses have to deal with a wide variety of patient’s issues and problems, with multiple difficulties and conflicts. Nurse’s judgment considers the core component of healthcare activities. This judgment directs her/his achievement and choices, not for her/him only, but for other healthcare professionals. Thus, nurses have to be competent observers and decision makers with reasoning and sound regarding their intervention and practice. Clinical judgment skills are essential aptitudes in nursing practice, predominantly, in nursing internship intermediary period, in which, a graduate nurse faced several predicaments and obstacles in such transitory experience from academic work to real labor. The present study aimed to develop a clinical judgment model to guide nursing interns in their nursing practice and assess its effectiveness on nursing interns’ clinical judgment knowledge and skills. The study passed through Quasi-experimental pretest-posttest research design. A stratified random sampling approach was used to recruit 50 nursing interns as an experimental group out of 305. The collection of data was carried out in the following hospitals of nurses’ intern’s training: Damanhur Medical National Institute, El Raee El Saleh, El Farok and Kafer El Dawar Hospitals, in Damanhur, Egypt. The Clinical Judgment Evaluation Sheet (CJES) was employed to collect necessary data. It included two parts: the Clinical Judgment Knowledge Test that was developed by Fathi & Aly in 2018, beside the Lasater Clinical Judgment Rubric (LCJR) that was developed by Kathie Lasater et al., in 2009. Results before using the developed model demonstrated that there were observed lacking in knowledge and skills about clinical judgment in nursing practice among experimental group. Then improvements were noticed after using the developed clinical judgment model. These results confirm that the use of an educational and self-learning reference such as the developed clinical judgment model is a successful tool for Egyptian nursing interns in nursing practice. Conclusion and recommendations: There is an understandable deficiency of nursing interns’ clinical judgment knowledge and skills in nursing practice. But, after using the developed clinical judgment model with them as a self-learning reference, it was confirmed that it is a helpful approach to develop and improve clinical judgment knowledge and skills of nursing interns. Creativity in using instructional aides and self-learning approaches is an essential ability that is important among nurse educators and preceptors who direct nursing intern’s performance. For further sturdies, replicate the study using the developed model with different subjects in nursing practice or develop new instructive models about creative, reflective, discovery, and decision-making models among nursing interns.
Household purchasing of cheap alcohol: Who would be most affected by minimum unit pricing?
Authors: Ejebu Ourega-Zoé , McKenzie Lynda , Ludbrook Anne 
Published: April 2018

Minimum unit pricing of alcohol has been proposed as a more effective policy for reducing alcohol-related harms than general taxation. Growing international evidence points to its effectiveness in targeting high risk drinkers, but concerns about the impact on low risk drinkers and those on low incomes remain. This paper uniquely models the potential effect on both low risk and low income purchasers in a Scottish subsample of UK panel data from introducing a minimum unit price and addresses the impact of missing income data on the results. Weekly household purchases of cheap off-sales alcohol from Kantar Worldpanel (2008-2010) are analysed using Hausman-Taylor, Tobit and OLS models. Explanatory variables include economic and demographic characteristics of the households, average alcohol purchasing level for all off-sales alcohol, and characteristics of alcohol products purchased. The number of cheap alcohol units purchased are predicted by income group and purchasing level. Results indicate that the amount of cheap alcohol purchased is positively associated with the average purchasing level for all off-sales alcohol. Lower occupational group is associated with purchasing more units of cheap alcohol. Type of alcohol and purchasing alcohol on promotion are also highly significant. Predicted quantities of cheap alcohol purchased are not higher for the low-income group. Households in the top decile of alcohol purchasing level are predicted to purchase between 18 units of cheap alcohol weekly (low income) and 24 units (intermediate income). There was no evidence of bias due to missing income data. Minimum unit pricing for alcohol will have most impact on households purchasing the most alcohol, at all income levels. Restrictions on promotions should be considered as these are also associated with increased purchasing of cheap alcohol. Published: Online April 2018.
Shipyard Block Logistics Simulation Using Process-centric Discrete Event Simulation Method
Authors: Jeong Yong-Kuk , Lee Philippe , Woo Jong Hun 
Published: April 2018

In recent years, shipyards have conducted various studies to accurately investigate their production capacities and improve the accuracy of their production plans. Nevertheless, frequent delays in schedules inevitably occur at production sites. Simulation-based techniques are used in various fields to solve similar problems, especially those related to predicting loads on facilities and upgrading production planning by considering various constraints. Process-centric simulation modeling techniques are used in shipyards because the shipbuilding process has different characteristics from the general manufacturing process. Conventional resource-oriented modeling techniques are inadequate to construct a simulation model to analyze the logistical behavior of shipyards. In this study, a process-oriented simulation modeling method is applied and improved through the identification and development of additional modules needed to simulate the behavior of shipyard logistics. The core of the simulation is improved using a logistic token that can analyze the physical movement effected by each process. Moreover, such process modeling modules as the geographic information system, the route search module, and the spatial arrangement module are developed and integrated into one solution.

1. Introduction
The shipbuilding industry in South Korea was affected by the recent global financial crisis. It has since suffered from a decline in global freight volume that has led to massive losses in all areas of commercial shipping and offshore plants since 2010. The shipbuilding industry in South Korea, especially large shipbuilders, received a large number of orders by competing in the market while reorganizing its business structure around the growth of offshore plants. This move was prompted by the flooding by Chinese shipbuilders of the local market with general merchant vessels (Fig. 1), as well as by prospects for the growing offshore plants' market due to crude oil depletion and high oil prices.
However, the industry has suffered astronomical deficits in recent years due to unexpected losses, and the three major shipbuilders in South Korea are experiencing high operating loss and debt-to-equity ratio (Fig. 2), leading to fears of insolvency. Additional losses are expected due to large backlogs in orders for offshore plants.

Published: April 2018

Dans notre monde globalisé, l’aire de jeux des acteurs n’est plus circonscrite à la structure, mais elle est, désormais, élargie au territoire. Cet effacement des frontières organisationnelles tend à favoriser le développement d’une logique partenariale, y compris en matière de gestion des ressources humaines (GRH) au regard des bouleversements de l’environnement socio-économique. C’est dans ce contexte actuel qu’une nouvelle forme émergente de GRH apparaît, se situant dans une démarche de RSE (responsabilité sociétale des entreprises) étendue qui ne se restreint plus uniquement à certains aspects sociaux.L’objectif de cet article est d’étudier une approche alternative de la GRH qui se veut plus sociétale. Nous nous attachons à répondre à la problématique suivante : comment instaurer une GRH sociétale en PME ? Utilisant l’approche contextualiste de Pichault et Nizet (2013), nous soulignons l’importance pour le dirigeant de mobiliser des acteurs tant internes qu’externes pour atteindre cet objectif. À partir du cas d’une PME française du secteur de l’économie solidaire, nous explorons, grâce à des récits de vie, des entretiens semi-directifs, des observations participantes et non participantes, ainsi que des analyses documentaires, le processus de construction de cette nouvelle forme de GRH.Nos résultats mettent en lumière trois étapes-clés : 1- l’émergence de cette GRH autour de la création d’un pacte social; 2- son évolution source d’adhésion et de frustration; et, enfin, 3-la diffusion de cette GRH alternative auprès des partenaires externes.

Published: April 2018

AbstractIn this paper, the spatial characteristics of a courtyard‐style settlement (Bahā/Bahī, originating from Buddhist Monasteries) are illustrated. First, the transition process of the Bahā/Bahī from a place of learning for celibate monks to an ordinary residence for non‐celibate monks is clarified. Second, a framework is developed to analyze the spatial structures of the present Bahā/Bahī, which was extracted from the spatial structure of typical Bahā/Bahī by examining the relationship between the courtyard's surrounding buildings and its accessibility. Lastly, the framework is applied to 65 exemplars of Bahā/Bahī in the old city area of Patan. As a result, 12 types of spatial structures were discovered, and the characteristics of the major types were determined.

AbstractCombination nanotherapies for the treatment of breast cancer permits synergistic drug targeting of multiple pathways. However, poor carrier degradability, poor synergism of the combined drugs, low drug release regulation, and a lack of control on final macromolecule solution conformation (which drives the biological fate) limit the application of this strategy. The present study describes the development of a family of drug delivery systems composed of chemotherapeutic (doxorubicin) and endocrine therapy (aromatase inhibitor aminoglutethimide) agents conjugated to a biodegradable poly‐l‐glutamic acid backbone via various linking moieties. Data from in vitro cytotoxicity and drug release assessments and animal model validation select a conjugate family member with optimal biological performance. Exhaustive physicochemical characterization in relevant media (including the study of secondary structure, size measurements, and detailed small‐angle neutron scattering analysis) correlates biological data with the intrinsic supramolecular characteristics of the conjugate. Overall, this study demonstrates how a small flexible Gly linker can modify the spatial conformation of the entire polymer–drug conjugate, promote the synergistic release of both drugs, and significantly improve biological activity. These findings highlight the need for a deeper understanding of polymer–drug conjugates at supramolecular level to allow the design of more effective polymer–drug conjugates.

AbstractPorous single crystals are promising candidates for solar fuel production owing to their long range charge diffusion length, structural coherence, and sufficient reactive sites. Here, a simple template‐free method of growing a selectively branched, 2D anatase TiO2 porous single crystalline nanostructure (PSN) on fluorine‐doped tin oxide substrate is demonstrated. An innovative ion exchange–induced pore‐forming process is designed to successfully create high porosity in the single‐crystalline nanostructure with retention of excellent charge mobility and no detriment to crystal structure. PSN TiO2 film delivers a photocurrent of 1.02 mA cm−2 at a very low potential of 0.4 V versus reversible hydrogen electrode (RHE) for photo‐electrochemical water splitting, closing to the theoretical value of TiO2 (1.12 mA cm−2). Moreover, the current–potential curve featuring a small potential window from 0.1 to 0.4 V versus RHE under one‐sun illumination has a near‐ideal shape predicted by the Gartner Model, revealing that the charge separation and surface reaction on the PSN TiO2 photoanode are very efficient. The photo‐electrochemical water splitting performance of the films indicates that the ion exchange–assisted synthesis strategy is effective in creating large surface area and single‐crystalline porous photoelectrodes for efficient solar energy conversion.

Published: April 2018

AbstractTunable Fano resonances and plasmon–exciton coupling are demonstrated at room temperature in hybrid systems consisting of single plasmonic nanoparticles deposited on top of the transition metal dichalcogenide monolayers. By using single Au nanotriangles (AuNTs) on monolayer WS2 as model systems, Fano resonances are observed from the interference between a discrete exciton band of monolayer WS2 and a broadband plasmonic mode of single AuNTs. The Fano lineshape depends on the exciton binding energy and the localized surface plasmon resonance strength, which can be tuned by the dielectric constant of surrounding solvents and AuNT size, respectively. Moreover, a transition from weak to strong plasmon–exciton coupling with Rabi splitting energies of 100–340 meV is observed by rationally changing the surrounding solvents. With their tunable plasmon–exciton interactions, the proposed WS2–AuNT hybrids can open new pathways to develop active nanophotonic devices.

Published: April 2018

AbstractOrganic frameworks represent an emerging family of advanced materials that can be precisely controlled at the atomic level. However, morphology control of organic frameworks remains perplexing and difficult, strongly limiting the advantages of organic frameworks in multiple practical applications. Herein, porphyrin organic framework hollow spheres (POF‐HSs) are fabricated by a template method as a proof of concept of organic frameworks with precisely controlled morphology. POF‐HS exhibits explicit chemical structures of 2D POF and an expected hollow structure. The morphology of POF‐HS is further regulated in terms of void size and shell thickness. Benefited from the polar chemical structures and the hollow spherical morphology, POF‐HS sufficiently mitigates the shuttle of polysulfides by taking the dual effects of chemical adsorption and physical confinement and functions as a desirable host material for sulfur cathode to endow lithium–sulfur batteries with high capacity, long cycling life, and excellent rate performance. The accurate synthesis of POF‐HSs demonstrates the highly controllable and versatile morphology of organic framework materials beyond precise integration of organic building blocks and represents infinite possibility of offering exotic organic frameworks for chemistry, sustainable energy, and material science.

Published: April 2018

AbstractA phosphine‐catalyzed domino reaction of allenoate and two molecular α,β‐unsaturated ketone is reported. In particular, this unexpected strategy incorporates [2+4] annulation and subsequent Michael addition into one reaction, thus providing a new access to polysubstituted dihydropyran derivatives in an efficient manner. The reaction optimization outcome reveals that not only the catalyst, but also the experiment parameters including the solvent and temperature play significant roles for the synthesis of the products. This protocol represents a new reaction mode of two basic chemicals involving C−C and C−O bond‐forming process. The present strategy also features the excellent stereoselectivity, broad substrate scope and atom economy.magnified image
Cross‐linked ultra‐high‐molecular‐weight polyethylene prepared by silane‐induced cross‐linking under in situ development of water

Published: April 2018

AbstractThis work aimed at providing a suitable method for preparing the cross‐linked ultra‐high‐molecular‐weight polyethylene (UHMWPE). First, UHMWPE was grafted with a silane compound using organic peroxide as an initiator in the molten state. Then, cross‐linking was performed by compression molding of the mixture of the silane‐grafted UHMWPE and CaC2O4·H2O. Water released from CaC2O4·H2O made the silane‐grafted UHMWPE cross‐link. In particular, no catalyst was added in the cross‐linking step. Fourier Transform Infrared results confirmed that the silane has been grafted onto the UHMWPE chain successfully and the grafting index varied with the dosage of the initiator. With the increasing of CaC2O4·H2O content, the gel ratio increased and average molecular weight of the cross‐linked UHMWPE decreased, which proved that the cross‐linked UHMWPE can be prepared by this method. Moreover, there existed different cross‐linked network structures (loose and tight networks) in the samples with the same gel ratio.

Published: April 2018

AbstractPromoting use of farmers’ markets (FMs) is a promising community‐level strategy to increase access to nutritious foods such as fruits and vegetables. Yet, FM shopping among people with Supplemental Nutrition Assistance Program (SNAP) benefits remains low. This research examined predictors of FM shopping among SNAP recipients living within 1 mile of a FM. A cross‐sectional survey of SNAP participants (N = 270) was conducted in 2015 in Cleveland and East Cleveland, OH, USA. Multinomial regression and zero‐truncated Poisson regression analyses were conducted to examine factors associated with FM shopping. Results indicate 48% reported shopping at a FM at least once in the past year, 26% had shopped at a FM before, but not in the last year, and 26% had never shopped at a FM. The multivariable analyses found awareness of FMs and a healthy food incentive program, and four dimensions of healthy food access are significantly associated with FM shopping among SNAP recipients. The food access dimensions included service delivery, spatial‐temporal, personal, and social access. Findings highlight modifiable leverage points for improving the reach of FMs among low‐income populations.

Published: April 2018

AbstractThe terminal zinc hydride complex [Tntm]ZnH (2; Tntm=tris(6‐tert‐butyl‐3‐thiopyridazinyl)methanide) is an efficient hydrosilylation catalyst of CO2 at room temperature without the need of Lewis acidic additives. The inherent electrophilicity of the system leads to selective formation of the monosilylated product (MeO)3SiO2CH (at room temperature with a TOF of 22.2 h−1 and at 45 °C with a TOF of 66.7 h−1). In absence of silanes, the intermediate formate complex [Tntm]Zn(O2CH) (3) is quantitatively formed within 5 min. All complexes were fully characterized by 1H and 13C NMR spectroscopy and single‐crystal X‐ray diffraction analyses. Density functional theory (DFT) calculations reveal a high positive charge on zinc and the increased preference of the ligand to adopt a κ3‐coordination mode.
Regioselective Formation of (E)‐β‐Vinylstannanes with a Topologically Controlled Molybdenum‐Based Alkyne Hydrostannation Catalyst

Published: April 2018

AbstractThe regioselective formation of (E)‐β‐vinylstannanes has been a long‐standing challenge in transition‐metal‐catalyzed alkyne hydrostannation. Herein, we report a well‐defined molybdenum‐based system featuring two encumbering m‐terphenyl isocyanides that reliably and efficiently delivers (E)‐β‐vinylstannanes from a range of terminal and internal alkynes with high regioselectivity. The system is particularly effective for aryl alkynes and can discriminate between alkyl chains of low steric hindrance in unsymmetrically substituted dialkyl alkynes. Catalytic hydrostannation with this system is also characterized by an electronic effect that leads to a decrease in regioselectivity when electron‐withdrawing groups are present on the alkyne substrate.

Published: April 2018

AbstractA simple and rapid method for 18F radiolabelling of [GaF3(BnMe2‐tacn)] by 18F/19F isotopic exchange is described. The use of MeCN/H2O or EtOH/H2O (75:25) and aqueous [18F]F− (up to 200 MBq) with heating (80 °C, 10 min) gave 66±4 % 18F incorporation at a concentration of 268 nm, and 37±5 % 18F incorporation at even lower concentration (27 nm), without the need for a Lewis acid promoter. A solid‐phase extraction method was established to give [Ga18F19F2(BnMe2‐tacn)] in 99 % radiochemical purity in an EtOH/H2O mixture.
