Published: April 2019

A learning program not only aims to make students understand and master what and how things happen, but also provide an understanding of why it happened. Thus, a lesson that emphasizes problem-solving becomes very important to teach. One form of learning that emphasizes the problem solving is to apply systematic approach to problem solving. This is a guide to perform an action that serves to assist a person in solving a problem. Problem solving steps based on systematic approach to problem solving consists of four stages, namely problem analysis, problem solving process planning, calculation operations, and checking answers and interpretation of results. This study is a classroom action research that aims to see the inceasing of student learning outcomes after applied systematic approach to problem solving. The subject of this research is 25 students of class VIIIA MTs Salafiyah Syafi'iyah Tebuireng Jombang. Instruments in this study is a matter of student learning outcomes on the material wake up space. This research was conducted in two cycles because in the second cycle has reached the indicator of success that students achieve the minimal clarity of at least 75%. The results showed that student learning outcomes in the first cycle reached 36% classical completeness, and in the second cycle of classical completeness of 84%. This shows that the application of systematic approach to problem solving can increase student learning outcomes.
Study and simulation with VHDL-AMS of the electrical impedance of a piezoelectric ultrasonic transducer
Authors: Merdjana Toufik , Chaabi Abdelhafid
Published: April 2019

Ultrasonic transducers are a key element that governs the performances of both generating and receiving ultrasound in an ultrasonic measurement system. Electrical impedance is a parameter sensitive to the environment of the transducer; it contains information about the transducer but also on the medium in which it is immersed. Several practical applications exploit this property. For this study, the model is implemented with the VHDL-AMS behavioral language. The simulations approaches presented in this work are based on the electrical Redwood model and its parameters are deduced from the transducer electroacoustic characteristics.

Published: April 2019

In this paper a hardware implementation of single-phase cascaded H-bridge three level multilevel inverter (MLI) using sinusoidal pulse width modulation (SPWM) is presented. There are a few interesting features of using this configuration, where less component count, less switching losses, and improved output voltage/current waveform. The output of power inverter consists of three form, that is, square wave, modified square wave and pure sine wave. The pure sine wave and modified square wave are more expensive than square wave. The focus paper is to generate a PWM signal which control the switching of MOSFET power semiconductor. The sine wave can be created by using the concept of Schmitt-Trigger oscillator and low-pass filter topology followed by half of the waveform will be eliminated by using the circuit of precision half-wave rectifier. Waveform was inverted with 180º by circuit of inverting op-amp amplifier in order to compare saw-tooth waveform. Two of PWM signal were produced by circuit of PWM and used digital inverter to invert the two PWM signal before this PWM signal will be passed to 2 MOSFET driver and a 3-level output waveform with 45 Hz was produced. As a conclusion, a 3-level output waveform is produced with output voltage and current recorded at 22.5 Vrms and 4.5 Arms. The value of measured resistance is 0.015 Ω that cause voltage drop around 0.043 V. Based on the result obtained, the power for designed inverter is around 100W and efficiency recorded at 75%.

Published: April 2019

This paper describes the design and implementation of Hardware in the Loop (HIL) system D.C. motor based wind turbine emulator for the condition monitoring of wind turbines. Operating the HIL system, it is feasible to replicate the actual operative conditions of wind turbines in a laboratory environment. This method simply and cost-effectively allows evaluating the software and hardware controlling the operation of the generator. This system has been implemented in the LabVIEW based programs by using Advantech- USB-4704-AE Data acquisition card. This paper describes all the components of the systems and their operations along with the control strategies of WTE such as Pitch control and MPPT. Experimental results of the developed simulator using the test rig are benchmarked with the previously verified WT test rigs developed at the Durham University and the University of Manchester in the UK by using the generated current spectra of the generator. Electric subassemblies are most vulnerable to damage in practice, generator-winding faults have been introduced and investigated using the terminal voltage. This wind turbine simulator can be analyzed or reconfigured for the condition monitoring without the requirement of actual WT’s.

Published: April 2019

The power plants behavior is crucial under faulted conditions and responses on protection systems. Major microgrid (MG) protection problem is the problem between the fault current in utilitygrid mode and microgrid mode. As conventional protection system doesn’t offer solution for all MG protection challenge, but it needs advanced protection strategy. Protection system must response to both the utilitygrid and MG faults. Fast response of protection is necessary as early as possible if the fault is occurs on utilitygrid and if the fault is occurs on MG, the protection scheme must seperate the small possible portion of MG to remove the fault. This work presents a typical MG protection scheme using digital relaying and satellite communication with wavelet detailed D1-coefficients of mother wavelet Bior 1.5. This research work is done for the detection, discrimination and locality of faults at distributed generators (DG’s) integration in multi-terminal transmission system. The algorithm tested under various faults with fault inception angles (FIA), fault impedances and fault distance of feeder line.
Complexidade da repetição
Authors: Lindenberg Lemos Carolina
Published: April 2019

A vastidão da presença da repetição nos textos convida a múltiplas abordagens. Neste artigo, propomos investigar a relação da repetição com a construção de tensão, da espera e, enfim, do ritmo textual. Para tanto, inquirimos sobre seu papel de manifestante de uma estrutura manifestada, que se organiza em torno das noções de aspecto e andamento, configuração que traçamos por meio da investigação de casos extremos: textos impossíveis. Em seguida, na comparação com os mecanismos da isotopia e da explicação, argumentamos por uma diferença de configurações de estilos tensivos, em que a repetição, inicialmente átona e sem direção, passa, num segundo momento, a engendrar pela falta um estilo ascendente de tensão. Por fim, a estrutura discutida é abordada do ponto de vista da globalidade do texto e a repetição é tratada como um fator na construção do regime de evolução do texto, que progride em pequenos círculos localizados, em grandes arcos ou por círculos entrelaçados numa progressão em espiral. O laço entre a falta e a surpresa que a repetição põe em jogo nos textos parece trazer uma solução tensiva à oposição entre a semiótica clássica e a visada inaugurada por Claude Zilberberg.

Esporte e guerra na Atenas democrática
Authors: Pritchard David M. , Souza Camila Diogo de , Sano Lucia
Published: April 2019

Este artigo considera o problema negligenciado do esporte de elite na Atenas Clássica. A democracia ateniense pode ter aberto a política a todos os cidadãos, mas não teve impacto na participação esportiva. Os esportistas desse Estado antigo continuaram a ser recrutados da elite. Portanto, é uma surpresa que os cidadãos que não pertenciam à elite considerassem o esporte como algo positivo e que tenham criado um programa inigualável de festivais esportivos locais em que gastaram uma quantia de dinheiro significativa. Eles também protegiam os esportistas das críticas públicas que normalmente eram direcionadas para a elite e suas atividades conspícuas. O trabalho dos cientistas sociais sugere que a explicação desse paradoxo se encontra na estreita relação que os atenienses não pertencentes à elite percebiam entre as competições esportivas e a maneira como conduziam a guerra. A conclusão inquietante desta palestra encontra-se na afirmação de que a abertura da guerra aos cidadãos não pertencentes à elite promovida pela democracia ateniense legitimou o esporte de elite.

A noção de artistas-curadores na 33ª Bienal de São Paulo: os artistas em histórica negociação com as instituições culturais
Authors: Ruoso Carolina , Rodrigues Rita Lages , Barbosa Daniela Fernandes , Souza Luise Soares Pereira de , Marcolino Luíza Bernardes de Matos
Published: April 2019

Neste artigo, situamos na História da Arte o debate artista-curador, primeiramente a partir dos acontecimentos em torno da proposta de criação de um Museu de Artistas Vivos na França e então abordamos como em meados do século XX, com o nascimento da profissão de curador de exposições, os artistas passam a questionar o papel do curador como mediador entre artistas e público. Com esta apresentação histórica sobre a presença desse debate nos mundos da arte, pretendemos situar a perspectiva apresentada na curadoria da 33ª Bienal de São Paulo ao longo dessa relação entre os artistas e as instituições culturais, em especial os museus de arte. Uma vez que este artigo integra uma pesquisa mais ampla a respeito de teorias e metodologias de curadoria de exposição, aprofundaremos nossa reflexão a respeito das definições que circularam na imprensa nacional e internacional a respeito do modelo proposto por Gabriel Pérez-Barreiro. A reflexão foi feita a partir deste corpus documental. Não foram abordados somente os textos da assessoria de comunicação, mas também conteúdo elaborado para as redes sociais, textos de catálogos e o material educativo produzidos pela equipe da 33ª Bienal de São Paulo, assim como as reportagens, matérias de jornalismo cultural e textos de crítica de arte que circularam nacional e internacionalmente sobre a exposição. Para desenvolver essa análise temos como referência o pensamento de Howard Becker, Jérôme Glicenstein, J. Pedro Lorente, entre outros autores.
Coal, Climate Justice, and the Cultural Politics of Energy Transition
Authors: Brown Benjamin , Spiegel Samuel J.
Published: April 2019

In the wake of the Paris Agreement on climate change, promises to phase out coal-fired power have suggested cause for optimism around energy transition globally. However, coal remains entangled with contentious development agendas in many parts of the world, while fossil fuel industries continue to flourish. This article discusses these entanglements through a climate justice lens that engages the cultural politics surrounding coal and energy transition. We highlight how recent struggles around phasing out coal have stimulated renewed critical debates around colonialism, empire, and capitalism more broadly, recognizing climate change as an intersectional issue encompassing racial, gender, and economic justice. With social movements locked in struggles to resist the development or expansion of coal mines, power plants, and associated infrastructure, we unpack tensions that emerge as transnational alliances connect disparate communities across the world. Our conclusion signals the need for greater critical engagement with how intersecting inequalities are coded into the cultural politics of coal, and how this shapes efforts to pursue a just transition.
Deliberative Ecologies: Complexity and Social–Ecological Dynamics in International Environmental Negotiations
Authors: Pickering Jonathan
Published: April 2019

Theories of complex systems can yield valuable insights for understanding the increasingly intricate networks of actors, institutions, and discourses involved in international environmental negotiations. While analysis of regimes and regime complexes has shed light on macro-level structures and relationships in global environmental politics, systemic analysis has gained less traction in making sense of micro-level interactions—such as communicative exchanges among participants—that occur within the sites of negotiation and how those interactions shape (and are shaped by) the broader dynamics of governance systems. This article shows how the conceptual lens of “deliberative ecologies” can bridge these levels of analysis by integrating theories of deliberative systems with ideas from complexity theory and social–ecological systems analysis. Drawing on evidence from United Nations climate change and biodiversity conferences between 2009 and 2018, I show how methods such as discourse analysis and process tracing can help to apply a deliberative ecologies perspective and thereby advance understanding of how discourses and deliberative practices diffuse through negotiating sites and how deliberation interacts with the social–ecological dynamics of those sites.

A new species of the tetraodontid fish genus Canthigaster was discovered during a recent expedition to theGambier Archipelago, French Polynesia. The new species, named Canthigaster criobe herein, is the only knownspecies of Canthigaster having 12–14 brown stripes along the body (stripes beginning in front of the eye,extending along the body, and abruptly ending at the base of the caudal fin). It also has 17 pectoral rays, the originof the anal fin inserts posterior to a vertical from the rear base of the dorsal fin and lacks spots on the caudal fin.Canthigaster criobe is currently known from a single specimen collected at the Gambier Archipelago. It appearsto be most similar to the white-spotted C. janthinoptera, a wide-ranging, Indo-Pacific species, which also inhabitsthe Gambier Archipelago, and to the Hawaiian endemic C. jactator forming a species complex that exhibitsincomplete lineage sorting. Specimens of C. axiologus, or an undescribed but very similar sibling species, werealso collected at the Gambier Archipelago. Molecular analysis of these samples reveals an affiliation with C.axiologus specimens collected from disjunct localities in the western Central Pacific. Canthigaster axiologus wasnot previously known to occur east of the Tonga Islands. Geographic range expansions are also reported for C. rapaensis and C. amboinensis.

The Key Role of Warm Rain Parameterization in Determining the Aerosol Indirect Effect in a Global Climate Model
Authors: Jing Xianwen , Suzuki Kentaroh , Michibata Takuro
Published: April 2019

Global climate models (GCMs) have been found to share the common too-frequent bias in the warm rain formation process. In this study, five different autoconversion schemes are incorporated into a single GCM, to systematically evaluate the warm rain formation processes in comparison with satellite observations and investigate their effects on the aerosol indirect effect (AIE). It is found that some schemes generate warm rain less efficiently under polluted conditions in the manner closer to satellite observations, while the others generate warm rain too frequently. Large differences in AIE are found among these schemes. It is remarkable that the schemes with more observation-like warm rain formation processes exhibit larger AIEs that far exceed the uncertainty range reported in IPCC AR5, to an extent that can cancel much of the warming trend in the past century, whereas schemes with too-frequent rain formations yield AIEs that are well bounded by the reported range. The power-law dependence of the autoconversion rate on the cloud droplet number concentration β is found to affect substantially the susceptibility of rain formation to aerosols: the more negative β is, the more difficult it is for rain to be triggered in polluted clouds, leading to larger AIE through substantial contributions from the wet scavenging feedback. The appropriate use of a droplet size threshold can mitigate the effect of a less negative β. The role of the warm rain formation process on AIE in this particular model has broad implications for others that share the too-frequent rain-formation bias.
Evaluating the Benefits of Merging Near-Real-Time Satellite Precipitation Products: A Case Study in the Kinu Basin Region, Japan
Authors: Mastrantonas Nikolaos , Bhattacharya Biswa , Shibuo Yoshihiro , Rasmy Mohamed , Espinoza-Dávalos Gonzalo , Solomatine Dimitri
Published: April 2019

After the launch of the Global Precipitation Measurement (GPM) mission in 2014, many satellite precipitation products (SPPs) are available at finer spatiotemporal resolution and/or with reduced latency, potentially increasing the applicability of SPPs for near-real-time (NRT) applications. Therefore, there is a need to evaluate the NRT SPPs in the GPM era and investigate whether bias-correction techniques or merging of the individual products can increase the accuracy of these SPPs for NRT applications. This study utilizes five commonly used NRT SPPs, namely, CMOPRH RT, GSMaP NRT, IMERG EARLY, IMERG LATE, and PERSIANN-CCS. The evaluation is done for the Kinu basin region in Japan, an area that provides observed rainfall data with high accuracy in space and time. The selected bias correction techniques are the ratio bias correction and cumulative distribution function matching, while the merged products are derived with the error variance, inverse error variance weighting, and simple average merging techniques. Based on the results, all SPPs perform best for lower-intensity rainfall events and have challenges in providing accurate estimates for typhoon-induced rainfall (generally more than 50% underestimation) and at very fine temporal scales. Although the bias correction techniques successfully reduce the bias and improve the performance of the SPPs for coarse temporal scales, it is found that for shorter than 6-hourly temporal resolutions, both techniques are in general unable to bring improvements. Finally, the merging results in increased accuracy for all temporal scales, giving new perspectives in utilizing SPPs for NRT applications, such as flood and drought monitoring and early warning systems.
Risk Factors in Alcoholic Cardiomyopathy
Authors: Kinney Evlin L. , Wright Robert J. , Caldwell John W.
Published: April 2019

Although a relationship has been suggested between abstinence from alcohol and improvement in left ventricular (LV) function, no long-term studies in large groups of patients have been done to confirm this impression or to demonstrate an effect on survival. To address these questions, the authors analyzed the out come in 105 male patients with alcoholic cardiomyopathy and 64 control male patients with nonalcoholic dilated cardiomyopathy. Survival data were available for all patients. The correlates of survival were assessed via the Cox propor tional hazards model. Variables considered were age, race, drinking pattern (current drinker versus former drinker), presence of coronary artery disease (CAD), hypertension, and diabetes, and these echo variables: left atrial (LA) size, posterior wall thickness, LV end diastolic dimension (LVDD), minimal E point septal separation, wall motion, presence of incomplete mitral leaflet clo sure (IMLC) or low cardiac output, and the ratio of relative wall thickness to LVDD. The two study groups were comparable with respect to all echocardio graphic variables. At a mean follow-up of 17.2 months ± 12.1 months, 42.85% of the alcoholics and 41% of the nonalcoholics had died. Nonsurvival in the alcoholic group was significantly associated with only two factors: an increased LVDD and the presence of IMLC. The drinking pattern was not significantly associated with survival. By contrast, in the nonalcoholics, the variables most closely related to survival were LVDD, low cardiac output, increasing age, and abnormal wall motion. Therefore: (1) the risk factors in alcoholic and nonalco holic cardiomyopathy are similar although IMLC appears to be a relatively specific prognostic factor for alcoholic cardiomyopathy and (2) abstinence from alcohol does not appear to improve survival.
Testing Crossover Studies for Carryover Effects
Authors: Cleophas Ton J.
Published: April 2019

For the study of cardiovascular disease, for instance, hypertension and angina pectoris, properly de signed crossover studies are to be preferred over parallel-design stud ies. Many statisticians now propose that these studies should always be tested for carryover effects. In the present paper the author analyzes the crossover studies published after No vember, 1985, in two general and two specialist journals (New England Journal of Medicine, Lancet, Angiol ogy, British Heart Journal). Of 73 pa pers only 23 (32%) consider the possi bility of carryover effects. Of these latter papers 12 (16%) perform sta tistical tests for these effects. The results of these tests were shown in only 7 papers (10%). It is concluded that there is a discrepancy between the statistical recommendations and the data presented in the literature.

Authors: Hasdai David , Fuchs Limor , Ohad Dan , Battler Alexander
Published: April 2019

This study was designed to examine the ability of color-labeled microspheres to depict different states of myocardial perfusion in a rabbit model of ischemia-reperfusion. A thread was passed under the left anterior descending artery (LAD) and the first left marginal artery of anesthetized New Zealand White rabbits. Blue-labeled microspheres (500/g body wt) were injected into the left atrium. The thread was tightened in rabbits belonging to the experimental group (n = 8), and red-labeled microspheres (500/g body wt) were injected. The snare was loosened, and yellow-labeled microspheres (500/g body wt) were injected before (n = 5) or after (n = 3) methylene blue injection. In animals belonging to the "sham" group (n = 4 and n = 2, respectively), the sequence of injections was similar, but the snare was not tightened. The animals were euthanized, and 0.3-1 g sections were cut from ischemic and nonischemic regions, as determined by methylene blue in the experimental subgroups and from the corresponding regions in the "sham" subgroups. The tissue samples were digested with 4 M KOH, ethanol 70%, and ultrasonication, and the microspheres were recovered by vacuum filtration. The dye was chemically removed from the microspheres, and the photometric absorption of each sample was determined.

There was no significant difference between the experimental and "sham" groups in baseline uptake of blue-labeled microspheres. Rabbits belonging to the experi mental subgroups had significantly lower mean uptake of red microspheres during ischemia relative to "sham" (0.51 ±0.08 vs 1.06 ±0.24 and 0.36 ±0.19 vs 0.91 ±0.12, respectively). After loosening of the snare there was no difference in uptake of yellow- labeled microspheres.

Color-labeled microspheres depict myocardial ischemia in the rabbit. The ability of color-labeled microspheres to depict reperfusion hyperemia remains to be proved.

Authors: Summers Bryant B. , Yates Mary , Cleveland Kerry O. , Gelfand Michael S. , Usery Justin
Published: April 2019

Purpose: The most recent published guidelines on Clostridium difficile–associated diarrhea (CDAD) developed by the Infectious Diseases Society of America (IDSA) were released in 2017 and outline its treatment based on severity of the disease and recurrence; however, a clear first-line agent has not been recommended specifically for severe CDAD. Methods: This retrospective chart review was approved by the institutional review board and consisted of three community hospitals and one academic medical center. To be included, patients need to meet criteria for severe CDAD and receive at least 72 hours of therapy. Patients received either oral vancomycin or fidaxomicin, in addition to other therapies for CDAD, and differences in outcomes such as cost obtained from a common charge center, rates of recurrence, time to recurrence as measured at time of positive to negative polymerase chain reaction (PCR) test, and mortality were assessed. Results: Of the 147 patients, 74 patients received fidaxomicin and 73 patients received oral vancomycin. The average hospitalization cost for patients receiving fidaxomicin was $129,338.69 and for patients receiving vancomycin was $153,563.81 ( P = .26). Recurrence rates were lower with fidaxomicin compared with vancomycin (6.8% vs 17.6%; P = .047), and time to recurrence was longer with fidaxomicin versus vancomycin, but not statistically significant (96.8 ± 45.9 days vs 63.2 ± 66.9 days; P = .321). Mortality, length of stay in the intensive care unit, and overall length of stay were similar between the two therapies. Conclusions: In the treatment of severe CDAD, recurrence rates were lower and time to recurrence was higher with fidaxomicin compared with oral vancomycin. A clear financial benefit has yet to translate from these known findings.
Understanding the use, and misuse, of Adverse Childhood Experiences (ACEs) in trauma-informed policing
Authors: Bateson Karen , McManus Michelle , Johnson Georgia
Published: April 2019

An increased awareness about how trauma impacts upon children and adults is vital for the identification of vulnerability, development of trauma-informed policing and strengthening the case for the prevention. ACEs provide an easily understandable framework which could help to develop trauma-informed practice and responses. However, there are potential misuses of ACEs in policing, for example using ACE scores or specific single ACEs as the basis for decisions or as intervention thresholds. In this article we review the current evidence with a focus on the strengths, current issues and risks in the use of ACEs across policing.
Emergence of Third Spaces: Exploring Trans Students’ Campus Climate Perceptions Within Collegiate Environments
Authors: Garvey Jason C. , Viray Sydnee , Stango Katie , Estep Claire , Jaeger Jae
Published: April 2019

Our study aims to understand trans students’ perceptions of campus climate, with a particular focus on students’ demographics, academic experiences, and cocurricular experiences. We use Bhabha’s concept of third space as an epistemological lens and Rankin and Reason’s transformational tapestry model as a theoretical framework. Using a national sample of 207 trans collegians from the National LGBTQ Alumnx Survey, we utilize regression analysis supplemented by an analysis of open-ended responses to highlight the experiences of trans respondents. Results demonstrate the relationship between trans students’ campus climate perceptions and year of graduation, outness, academic training, and LGBTQ academic/cocurricular experiences. We close by discussing campus climate experiences and the third space that trans students must navigate within colleges and universities, and we provide recommendations for higher-education practitioners and scholars.
Play It Again, Sam! An Analysis of Constructive Replication in the Organizational Sciences
Authors: Köhler Tine , Cortina Jose M.
Published: April 2019

Replication is an essential part of any science, confirming or adjusting our understanding of the world through repeated exploration of a phenomenon of interest. While there has been an increased interest in the role of replication studies, there also exists skepticism regarding the need for more replication. Our empirical analysis of 406 recent studies that use the term “replication” suggests that this criticism stems from a lack of appreciation of the different forms that replication can take, the prevalence (or lack thereof) of many of these forms, and the objectives that are met by one of the least common forms, constructive replication. As such, the purposes of our paper are (1) to explore the different forms that constructive replication can take and the objectives at which each can be directed, (2) to distinguish these forms from other forms of replication with which they are often confused, (3) to determine how common each form of replication is in our field, and (4) to provide concrete examples of different forms of constructiveness from published studies in order to pave the way towards more (and more useful) replications in the future.
Does the constitution matter? Semi-presidentialism and the origin of hegemonic personalist regimes
Authors: Yan Huang-Ting
Published: April 2019

This study examines hegemonic personalist regimes (HPRs) and argues that semi-presidential dictatorships are more likely to evolve into HPRs than parliamentary systems or presidential autocracies. In presidential autocracies, elites delegate power to dictators who control the military to eliminate threats from the opposition. In parliamentary systems, elites are more likely to build power-sharing parties through which parliamentary opposition can be defeated, often evolving into single-party regimes. In semi-presidential autocracies, elites delegate power to dictators in exchange for investments, support of their agendas, or defeat of the opposition, which can lead to personalist rule supported by a dominant party or HPR. This study verified this phenomenon using logistic regression. In addition, this study examined three possible challenges: unstable equilibrium, reverse causality and institutional variation within semi-presidentialism. In sum, the incentive structure inherent in semi-presidential systems paves the way for the rise of HPRs.
Attachment dimensions and forgiveness of others: A meta-analysis
Authors: Hirst Shannon L. , Hepper Erica G. , Tenenbaum Harriet R.
Published: April 2019

Forgiveness, as a response to interpersonal transgressions, has multiple societal and individual benefits. Individual differences in attachment have been identified as a predictor not only of forgiveness but of state responses frequently associated with forgiveness. The current meta-analysis is the first systematic analysis of the effect of attachment dimensions (i.e., anxiety and avoidance) on forgiveness of others. Analysis of published and unpublished studies ( k = 26) identified significant, small-to-medium effects of attachment anxiety ( r = −.25) and attachment avoidance ( r = −.18) on forgiveness of others. No significant difference was obtained between measures of state and trait forgiveness. The moderating effects of study paradigm, attachment measure, publication type, and sample population were also investigated. The findings of a stable negative effect of insecure attachment dimensions on forgiveness of others provide a base for future research that may focus on reducing attachment anxiety and avoidance to support forgiveness.
Non-specialist palliative care: A principle-based concept analysis
Authors: Nevin Mary , Smith Valerie , Hynes Geralyn
Published: April 2019

Background:

Building palliative care capacity among all healthcare practitioners caring for patients with chronic illnesses, who do not work in specialist palliative care services (non-specialist palliative care), is fundamental in providing more responsive and sustainable palliative care. Varying terminology such as ‘generalist’, ‘basic’ and ‘a palliative approach’ are used to describe this care but do not necessarily mean the same thing. Internationally, there are also variations between levels of palliative care which means that non-specialist palliative care may be applied inconsistently in practice because of this. Thus, a systematic exploration of the concept of non-specialist palliative care is warranted.

Aim:

To advance conceptual, theoretical and operational understandings of and clarity around the concept of non-specialist palliative care.

Design:

The principle-based method of concept analysis, from the perspective of four overarching principles, such as epistemological, pragmatic, logical and linguistic, were used to analyse non-specialist palliative care.

Data sources:

The databases of CINAHL, PubMed, PsycINFO, The Cochrane Library and Embase were searched. Additional searches of grey literature databases, key text books, national palliative care policies and websites of chronic illness and palliative care organisations were also undertaken.

Conclusion:

Essential attributes of non-specialist palliative care were identified but were generally poorly measured and understood in practice. This concept is strongly associated with quality of life, holism and patient-centred care, and there was blurring of roles and boundaries particularly with specialist palliative care. Non-specialist palliative care is conceptually immature, presenting a challenge for healthcare practitioners on how this clinical care may be planned, delivered and measured.
