Scholars, States, and Human Rights
Authors: Weingand Yanik
Published: July 2022

This article investigates the similarities between different critiques towards the international human rights system from academia and state-actors. On the one hand, there are the critiques from scholars of the Third World Approaches to International Law (TWAIL) movement. On the other hand, there are critical points raised towards the international human rights system by China, Cuba, and Egypt in the reports from the first three cycles of their respective Universal Periodic Review (UPR) within the United Nations Human Rights Council (UNHRC). Through a literature review, the TWAIL critiques were first categorized and then worked into a framework of three basic pillars: the culture critique, the rhetoric critique, and the model critique. This framework was subsequently applied to the reports by way of a simplified Qualitative Content Analysis in order to extrapolate the similarities of the critiques from these two unlikely groups of actors.

Published: July 2022

The article first uses the fractional derivative to define a new fractional bounded variation function space. This method constructs the corresponding electronic information image model denoising mask by setting a smaller fractional integration order. The experimental results show that the image denoising algorithm based on fractional integration can not only improve the signal-to-noise ratio of the image compared with the traditional denoising method, but also can better retain the details of the edge and texture of the electronic information image.
A Script-Driven Approach to Mapping Satellite-Derived Topography and Gravity Data Over the Zagros Fold-and-Thrust Belt, Iran
Authors: Lemenkova Polina
Published: July 2022

Integrated geophysical mapping benefits from visualizing multi-source datasets including gravity and satellite altimetry data using 2D and 3D techniques. Applying scripting cartographic approach by R language and GMT supported by traditional mapping in QGIS is presented in this paper with a case study of Iranian geomorphology and a special focus on Zagros Fold-and-Thrust Belt, a unique landform of the country affected by complex geodynamic structure. Several modules of GMT and ’tmap’ and ’raster’ packages of R language were shown to illustrate the efficiency of the console-based mapping by scripts. Data sources included high-resolution raster grids of GEBCO/SRTM, EGM-2008, SRTM DEM and vector geologic layers of USGS. The cartographic objective was to visualize thematic maps of Iran: topography, geology, satellite-derived gravity anomalies, geoid undulations and geomorphology. Various cartographic techniques were applied to plot the geophysical and topographic field gradients and categorical variations in geological structures and relief along the Zagros Fold-and-Thrust Belt. The structures of Elburz, Zagros, Kopet Dag and Makran slopes, Dasht-e Kavir, Dasht-e Lut and Great Salt Desert were visualized using 3D-and 2D techniques. The geomorphometric properties (slope, aspect, hillshade, elevations) were modelled by R. The study presented a series of 11 new maps made using a combination of scripting techniques and GIS for comparative geological-geophysical analysis. Listings of R and GMT scripting are provided for repeatability.

Published: July 2022

Focusing strictly to the braking assembly system, it is an important key factor for safety, does not matter if it can be found on cars, motorcycles, planes or bicycles. The principal aspect is to transform the energies that act on the system, which are kinetic and potential, then leads to a speed decrease of the vehicle until it stops.

The purpose of this paper is to analyze five possible variants of the geometry of the brake disc, each geometry being different from the other. Because for a more efficient release of heat, the five chosen geometries of the discs have on their surface vanes, holes, in order to remove heat from their surface. For the actual making of the discs, the chosen models were made and designed in the CATIA V5 design program.

The next step in this work was to perform analyzes and simulations for the selected disks. At the same time, the material chosen for them was considered. The 3D models were imported into the ANSYS analysis program, where individual analyzes were performed for each brake disc, and a comparison was made between the values of each one.
Legal protection of the human genome – excessive or disproportionate?
Authors: Plonka-Syroka Bozena , Stych Marek
Published: July 2022

Throughout the 20th century, life expectancy in developed countries considerably increased from 40 to 70 years. This stemmed mainly from the technological advancements in medicine that have been taking place since the end of the 19th century. Although the development of contemporary clinical medicine is undoubtedly beneficial to public health, it may also entail certain hazards. Hence, both in international and national law systems one can find legal regulations setting the limits of this development and taking into account the principles of public safety in its contemporary understanding. Both the human being as a whole and the human genome are protected de jure. The article attempts to answer the question whether the currently binding genome regulations are excessive or disproportionate. The authors use the dogmatic-legal and the theoretical-legal methods in the study. The article ends with conclusions.

Authors: Panjaitan Arief
Published: July 2022

A pedestrian bridge is a structure linking a pedestrian or bike path over or around a major roadway, railway, or waterway. The truss bridge (TRB) and the bridge with a castellated beam (CBB) are the common models of the pedestrian bridge. Past studies have revealed the structural behavior of TRB and CBB, but the performances of both bridges have not yet been comparatively confirmed. This study examined the TRB and CBB structural performances to obtain the better bridge model due to applied loading. The research was started by establishing the bridge models and employing the load combinations. The analysis resulted in the internal forces and they were used to design the bridges. The design is referred to as the SNI-1729-2020. This research revealed that the TRB exhibited structural performances, i.e., deflection and internal force, better than those of the CBB. Nevertheless, due to the many steel members, the TRB presented a heavier bridge than the CBB.

Desa Menari memiliki potensi budaya dan ekonomi kreatif yang terintergrasi dalam tiga konservasi, yaitu konservasi kesenian masyarakat, konservasi dolanan tradisi masa lalu dan konservasi petani peternak. Misinya adalah sesuai dengan konsep Desa Menari (Menebar Harmoni, merajut Inspirasi dan Menuai Memori). Di tahun 2018, Desa Menari dikunjungi 1500 hingga 2000 pengunjung dengan pemasukan Rp 100 juta hingga Rp 260 juta. Namun, kondisi di tahun 2020 mengalami penurunan drastis dalam sektor pariwisata akibat pandemi Covid 19, karena belum bisa menerima kunjungan wisatawan. Padahal untuk menumbuhkan produktivitas masyarakat Desa Menari, mereka menjual hasil ekonomi kreatif di Pasar Rakyat ketika ada kunjungan wisatawan. Pemasaran ekonomi kreatif juga dilakukan di Rest Area Salatiga namun juga masih sepi pengunjung karena rest area baru beroperasi. Selain permasalahan pemasaran, adapula persoalan adopsi teknologi yang masih rendah keterlibatan dengan pengikut akun media social Omah Cikal. Pada dasarnya konten menjadi kunci untuk bisa menarik interaksi dan berkomunikasi secara online. Dengan situasi tatap muka yang dikurangi, maka Kelompok Sadar Wisata (Pokdarwis) Desa Menari melalui omah cikal tetap bisa mengedukasi dan membentuk reputasi kebudayaan lokal nya dengan cara membangun narasi digital agar jangkauan audiens lebih luas. Reputasi ekonomi kreatif dapat dibentuk menggunakan tutur cerita yang dibangun di“own media”nya di akun media sosial resmi Desa Menari. Maka diperlukan pengabdian kemitraan masyarakat untuk memberikan pelatihan aktivitas Public Relations dengan pendekatan storytelling. Ketrampilan yang diusulkan adalah digitalisasi Desa Menari yang meliputi pengelolaan konten digital dan pembuatan narasi storytelling.

Stereospecific Synthesis of Silicon-Stereogenic Optically Active Silylboranes and their Application to Synthesis of Chiral Organosilanes
Authors: Wang Xihong , Feng Chi , Kubota Koji , Ito Hajime
Published: July 2022

Silylboranes have widespread applications in organic synthesis as versatile silylation reagents, which has inspired interest in studying methods for their synthesis. Silicon-stereogenic optically active silylboranes would allow the introduction of silicon-stereogenic silyl groups into various molecules. However, the synthesis of such silicon-stereogenic silylboranes remains unknown to date. Here, we report the first synthesis of silicon-stereogenic optically active silylboranes via stereospecific Pt(PPh3)4-catalyzed Si–H borylation of silicon-stereogenic hydrosilanes in high yield and perfect enantiospecificity (100% es) with retention of the configuration. Furthermore, the first characterization of silicon-stereogenic silyl-boranes by single crystal X-ray diffraction analysis was reported. This protocol is suitable for the stereospecific synthesis of silicon-stereogenic trialkyl-, dialkylbenzyl-, dialkylaryl-, and diarylalkyl-substituted silylboranes with excellent enantiomeric purity. The utility of the silicon-stereogenic silylboranes is demonstrated in silicon–silicon cross-coupling, transition-metal-catalyzed carbon–silicon bond-forming cross-coupling, and conjugate addition reactions with perfect enantiospecificity (100% es). The absolute configurations of the chiral silicon products were successfully confirmed by single-crystal X-ray diffraction analysis. The established synthetic strategy can be expected to expand the chemical space of silicon-stereogenic optically active organosilicon compounds with potentially interesting properties.

Modification of porphyrins by a replacement of N atom(s) with a heteroatom(s), resulted in so called heteroporphyrins, exhibits interesting physicochemical properties. In this work, the spectral properties of ions and neutral forms of 5,10,15,20-tetraphenyl-21,23-dithia porphyrin (S2PP) and 5,10,15,20-tetraphenyl-21-thia-porphyrin (HSPP) have been investigated. According to spectrophotometric analysis in acetonitrile – perchloric acid solution, the dication H2S2PP2+ reveals an ability to coordinate two ClO4- anions, which not happens for H3SPP2+. This fact observed in UV–Vis absorption spectra indicates the possibility of exhibiting chemosensory properties of S2PP molecules. Geometries of the neutral and ionized forms were derived from B3LYP/cc-pVTZ calculations. Perimeters of the cavities increase in the series: H2PP–HSPP–S2PP. This trend is kept for the ionized forms; protonation expands the cavity perimeter. Electron density distributions were analyzed in terms of quantum theory atoms in molecule (QTAIM). The UV-vis spectra simulated by TDDFT fits with the experimental results.
Unsupervised Data-Driven Reconstruction of Molecular Motifs in Simple to Complex Dynamic Micelles
Authors: Cardellini Annalisa , Crippa Martina , Lionello Chiara , Afrose Syed Pavel , Das Dibyendu , Pavan Giovanni Maria
Published: July 2022

The reshuffling mobility of molecular building blocks in self-assembled micelles is a determinant key of many interesting properties, from emerging morphologies and surface compartmentalizations to dynamic reconfigurability and stimuli-responsiveness of these supramolecular soft particles. However, such complex structural dynamics is typically non-trivial to be elucidated, especially for multi-component assemblies. Here we show a machine-learning approach that allows to reconstruct the structural and dynamic complexity of mono- and bi-component surfactant micelles from high-dimensional data extracted from equilibrium molecular dynamics simulations. Unsupervised clustering of smooth overlap of atomic position (SOAP) data enables to identify the main local molecular environments in a micelle, and to retrace their composition and dynamics, in terms of the exchange of surfactants among micelle clusters. Provided that there is sufficient difference between surfactants that are mixed in a multi-component micelle, this approach can effectively recognize diverse surfactant types even in an exquisitely agnostic, unsupervised way: solely based on their relative displacements and dynamic motions, and without prior information on the molecular species present in the system.

In medicinal field, delivery agent is a very important substance to improve the efficiency of drug used by improving the stability and preventing the degradation of drug during the medical treatment. Due to these important roles of the drug delivery agent, the search of effective agent is continuously in progress. In this respect, this current research was carried out to synthesize cellulose–polylactic acid (cellulose-PLA), as a potential delivery agent of rifampicin for the curing of tuberculosis. Cellulose was isolated from cassava bagasse, while PLA was obtained from commercial supplier. The two raw materials were used to synthesize cellulose–PLA in 3.5% HCl as solvent under magnetic stirring. The product obtained was then characterized by Fourier-Transform Infrared spectroscopy (FTIR), Particle-Size Analysis (PSA), and Scanning Electron Microscopy (SEM). The FT-IR result showed the presence of hydroxy (3446 to 3429 cm−1) and carbonyl (1757 to 1759 cm−1), confirming the formation new bond between cellulose and PLA. The PSA characterization displays a particle-sizes of PLA are in the range of 960–92780 nm, while cellulose–PLA are in the range of 100–17730 nm demonstrating that cellulose-PLA combined to form more compact structures. The results of SEM analysis indicate the distinct feature of cellulose-PLA, and combination of the features in the cellulose and PLA image. The results of the dissolution test carried out two different concentrations of rifampicin revealed that the optimum dissolution (8.42%) was achieved with cellulose–PLA of 0.3%, dissolution time of 12 h, and pH of 7.4.

Corn is an essential agricultural commodity since it is used in animal feed, biofuel, industrial processing, and the manufacture of non-food industrial commodities such as starch, acid, and alcohol. Early detection of diseases and pests of corn aims to reduce the possibility of crop failure and maintain the quality and quantity of crop yields. A decision tree is a nonparametric classification model in statistical machine learning that predicts target variables using tree-structured decisions. The performance of this model can increase significantly if the continuous predictor variables are discretized into valid categories. However, in some cases, the result does not provide satisfactory performance. The possible cause is the ambiguity in discretizing predictor variables. The incorporation of fuzzy membership functions into the model to resolve discretization ambiguity issues. This work aims to classify diseases and pests of corn plants using the decision tree model and improve the model’s performance by implementing fuzzy membership functions. The main contribution of this work is that we have shown a significant improvement in the decision tree model performance by implementing fuzzy membership functions; S-growth, triangle, and S-shrinkage curves. The proposed fuzzy model is better than the decision tree model, with an average performance increase from the largest to the smallest; kappa (12.16%), recall (11.8%), F-score (9.71%), precision (5.08%), accuracy (3.23%), specificity (1.94%), and AUC (0.49%). The combination of bias and variance generated by the proposed model is quite small, indicating that the model is able to capture data trends well.

Modification of Mg/Al-LDH intercalated metal oxide (Mg/Al-Ni) was successfully formed by the coprecipitation method at pH 10, which is indicated by the XRD diffraction, FTIR spectrum, and BET analysis. Mg/Al-LDH increased surface area after intercalated Ni from 8.621 m2/g to 9.821 m2/g and improved performance in process regeneration which can be used in the three cycles. Mg/Al-LDH after intercalated metal oxide (Ni) increases adsorption capacity of is 69.930 mg/g to 71.429 mg/g for methyl orange (MO) and 77.519 mg/g to 98.039 mg/g for methyl red (MR). Equilibrium time on the adsorption process occurred at 90 minutes with adsorption kinetics followed pseudo-second-order (PSO). Thermodynamic parameters indicate that the adsorption process is spontaneous and endothermic with the physical adsorption process.

Published: July 2022

The droplet combustion and thermal behavior of pure coconut oil (PCO), clove oil, and their mixture were experimentally investigated. The mixture fuels were PCO and clove oil at the percentage of 10% based on volume (PCO-CO10). The experimental method uses droplet combustion and thermogravimetric analysis. The fuel droplet was suspended in the junction of k-type thermocouple and ignited by a coil heater. The ignition and combustion processes of droplets were recorded using a digital single-lens reflex camera at 25 fps. Thermogravimetric analysis with alumina crucible was prepared to investigate the thermal behavior of fuel. The result showed that the sequence of ovoid flame for PCO and PCO-CO10 take place until 0.4 second and 0.44 second, respectively. Complete combustion was explained in that sequence. The ovoid flame was formed when eugenol, terpene, and lauric acid were evaporated first in both PCO and PCO-CO10. Minimum ovoid flame takes place in clove oil due to soot tendency in the burning process that marked flame as the open tip. PCO-CO10 has the highest peak temperature due to the presence both of double carbon chains in fatty acid and aromatic ring structures, which were easy to decompose in high energy input. Clove oil was the lowest onset temperature, which indicates more volatile matter in this fuel and PCO has the highest thermal stability due to the fatty acid component in their fuel.

The pandemic period has caused antibiotics highly recommended to cure infections. The use of macrolide antibiotics has greatly increased recently due to outbreaks of diseases that attack the human respiratory tract all of part of the world. One member of the macrolide group is erythromycin ethyl succinate which has low solubility in water. Therefore, this study aims to convert erythromycin ethyl succinate into lipid nanoparticles in an attempt to increase solubility. The method for the formation of nanoparticles is heating emulsification and homogenization. The results obtained in the form of formula 1 (F1) showed the percent encapsulation of 85.688±0.30641. The physical properties were that it has a size of 398.9±1.4 nm, a PDI of 0.3895±0.0015, and zeta potential of -17.45±0.15 mV respectively. The stability was determined by an accelerated test by the influence of extreme temperature and mechanics affecting the stability of the particles as an indication of decreasing the pH and particle precipitation. The solubility of erythromycin ethyl succinate in the form of lipid nanoparticles was increased in a comparison with the pure substance of erythromycin ethyl succinate.

Published: July 2022

Hydrochar of Salacca zalacca peels (HC-SP) is prepared by hydrothermal carbonization treatment of Salacca zalacca peels (SP) obtained from local fruits at Palembang, South Sumatera, Indonesia, with the resulting yield weight reaching 90%. Materials are characterized using the XRD diffraction, FTIR spectrum, and SEM-EDX. The XRD pattern shows the characteristics of the formation of amorphous compounds. The FTIR spectrum confirms the presence of functional groups O-H, C-H, C=C, and C-O. Data of SEM-EDX show that materials have heterogeneous morphologies, form aggregates, and in HC-SP materials there is an increase in carbon content from the initial material. The capacity of SP in the congo red (CR) adsorption process is 33.003 mg/g and increases to 133.333 mg/g in HC-SP. The maximum dye adsorbed was achieved at pH 4. The adsorption kinetics followed PSO with the equilibrium adsorption occurring at 90 minutes, and the adsorption isotherm followed the Langmuir isotherm with the value of R2 closer to the value of 1. A positive 4H value indicated that the adsorption is an endothermic process. In contrast, an 4S value suggested that the degree of irregularity in the adsorption process is small in large concentrations. Based on data regeneration ability, materials of SP and HC-SP can be used in the three cycles regeneration process of the CR adsorption process. The adsorption process of CR occurs physically and chemically based on enthalpy values and FT-IR data after being adsorbed with CR.
Analyzing the impact of phase decoupled harmonic load flow on an unbalanced distribution system
Authors: Raju B. Sreenivasa , Sivanagaraju S.
Published: July 2022

Power quality problems in the distribution system can sometimes lead to unbalanced and uncontrolled conditions during operation. This situation can be overcome by estimating the parameters of the distribution system, thus solving the problem of load distribution. The presence of harmonic loads in the distribution system complicates the operation of the system and requires new algorithms to obtain a specific solution rather than an approximate solution. Taking all these aspects into account, this paper presents a new methodology based on decoupling by formulating intrinsic and mutual impedance networks and mathematical modeling of these networks along with ancillary methodology. This methodology is applied to solve an unbalanced distribution system with 13 nodes and 11 harmonic loads connected in different parts of the system. The obtained results are confirmed by the existing literature methods.
Enclosed Spaces, Boundless Possibilities: Investigating the Status Quo of Romanian Prison Libraries Through a Survey-based Approach
Authors: Babei Vlad
Published: July 2022

The purpose of this study is to draw attention to the current state of Romanian prison libraries by focusing on such aspects as the legal framework under which they operate, their organization and facilities, the management of their collections and the policies employed to this end, the staff in charge of these structures, as well as library usage and satisfaction. Moreover, the present study aims to highlight the main obstacles and difficulties that Romanian prison libraries are struggling with at the moment, and to provide a few minimal recommendations for the improvement of their services and overall quality. In order to elicit relevant data, a questionnaire – comprising 48 both open and close-ended items – was designed and mailed to the 45 existing Romanian correctional facilities between early December 2021 and mid-January 2022. Albeit the response rate was 66.6%, the author has managed to identify a number of common issues that prevent Romanian prison libraries from functioning at an optimal level, such as the insufficient funding and inadequate space, the lack of professionally trained librarians, and the absence of a coherent collection development policy. Although those in charge of prison libraries strive to make the best of the available resources – and there are a few notable cases –, Romanian prison libraries are in dire need of both financial and managerial remodeling.

Public markets were once a very important place to a city. However with the growth of the city and heavy usage of traffic, big-box supermarkets start to find its way into the city. The supermarket revolution had overtaken the public markets identity in most urban cities. However, due to recent events known as the supermarket bully-boy tactics, brought an awareness to the public. In result, the public starting to turn away from these chain supermarkets and start to support the local produce. However, even with the support from the public, public markets still find hard to grow within the urban city.

This thesis investigates how a hybrid building could be the solution for the public markets in the city from being evicted due to urban land development. This is investigated by incorporating the public market as part of the building’s design development. Besides incorporating the market into the building, the nature of the market as a public place needed to be retained.

As the chosen site for this project is situated in an area between two high activity neighborhoods, the project’s design seeks to channel the vibrancy from the surrounding area through the building. The research had identified several public programs other than the market to be integrated into the project’s design. The aim is to design a vibrant urban public place, engaging with the people and building a sense of community within the inner city area.

This design-led research thesis breaks-down the project’s complexity into three separate faces to be investigated. The first design phase introduces the overall design scheme and describes the programs relativity to the project. This phase carried on with the investigation and documentation of the form finding process through a series of physical modelling and images.

This then led to the second phase of the research involving the market. This phase investigates the physical realms in public market design from a socio-spatial perspective and design principles for making farmer’s markets a public space. The investigation considers the circulation route defined by the promenade and the layout of the stalls. Diagrammatic analysis was conducted throughout these investigations. The outcome of these investigations will reflect on the latter decision for the overall design outcome.

The research carried on to phase three where the final design outcome of the design is documented. The design process is generated through the combination of investigation outcomes gathered in phase one and two.
The Relationships Among Rumination, Narrative Coherence, and Well-Being in a Community Sample of Adolescents

The ability to tell a coherent autobiographical narrative, in particular the ability to link life events to ones sense of self (causal coherence) and to develop a consistent theme and achieve a sense of resolution in one’s memory narratives (thematic coherence), is related to increased well-being in adults. In contrast, in early-adolescence, increased causal and thematic coherence are associated with decreased psychological well-being but the reason for this is unclear. The current study examined whether rumination mediated the relationships between narrative coherence and both life satisfaction and depression in a community sample of 190 adolescents (mean age = 16.31 years). Contrary to prediction, causal and thematic coherence were positively related to life satisfaction and negatively related to depression. Participants were less proficient in causal than thematic coherence, and rumination was a weak mediator of the relationships between causal, but not thematic, coherence and both life satisfaction and depression. In contrast, thematic coherence was found to moderate the relationship between rumination and life satisfaction for the whole sample, and also the relationship between rumination and depression for male participants with a moderate to high tendency to ruminate. Results indirectly support the theory that rumination mediates the negative relationship between narrative coherence and well-being found in early adolescence. By mid-adolescence however, individuals appear to be proficient in the use of narrative coherence and this increased proficiency may help to improve their well-being. Longitudinal research examining the relationships among narrative coherence, rumination, and well-being throughout adolescence is needed to better understand the unique ways in which causal and thematic coherence serve to influence adolescents’ psychological functioning.
Re-Visioning Guqin Performance through Interface Design, Digital Measurement, and Signal Processing

The guqin is the oldest Chinese stringed instrument with a history of over 3000 years. The most distinct characteristics of the instrument are the fluid modulation of pitch, and the dynamics and timbre in the tones created by the combination of the left and right hand finger techniques, which require many years for mastery of their execution and application. Most guqin research remains limited to its history, aesthetics, philosophy, sonic properties and notation system. Despite its long history and rich literature, much remains to be discovered about the embodied relationship between the intricacies of ancillary and auxiliary movements of master musicians and their rich colour, timbre and subtle nuances in sound.

This research addresses the significance of guqin hand gestures, and presents an approach for re-visioning guqin performance: firstly, by developing a physical gesture acquisition system to investigate the guqin music tradition through the measurement of hand gesture techniques; secondly, by exploring the compositional and performative potential of the developed acquisition system as a musical interface, and how guqin playing schema can evoke new amalgams of electro-instrumental music; and thirdly, by utilizing the enhanced understanding of guqin hand gestures to guide the design and development of new musical interfaces. These objectives define the re-visioning of guqin performance, and are described and detailed throughout this document. The implications of this research include preserving and inheriting guqin playing styles; supplementing and advancing pedagogy; revitalizing guqin music tradition through technological means; and utilizing the embodied performer-instrument relation to advance the state of the art in human-mechatronic musical interaction.
“What a difference a day makes” - Second trimester termination of pregnancy in the gynaecology ward: A case study
Authors:   , Burns Margaret Mary
Published: July 2022

The focus of this study are the nurses who care for women undergoing termination of pregnancy in the second trimester. Termination of pregnancy (abortion) is the deliberate ending of a pregnancy. In New Zealand for the year ending December 2015, 13,155 abortions were performed and of these, 553 abortions were performed after the 12th week of pregnancy (second trimester). Changes to how abortions are undertaken has resulted in increased participation by nurses and midwives in the process, where the resulting products of conception often resemble a fully formed foetus. Despite abortion being so widely accessed, little is known about the attitudes, opinions or feelings of the nurses who deliver the care.

The purpose of this study was to explore issues for nurses who provide care for women undergoing second trimester termination of pregnancy in the gynaecology inpatient setting. Case study methodology was used. This study used face to face semi structured interviews and retrospective clinical note review as data collection methods. Themes which were identified in the interviews included: staff experiences and attitudes, strategies for managing demands and challenges, and training and support. The study found that whilst the stance of the nurses who participated in second trimester termination of pregnancy care was largely pro-choice they were not necessarily immune to the stressors associated with the processes of termination of pregnancy, particularly as the gestational age of the pregnancy advances. Support for nurses who work in abortion services is at best haphazard and when compared to the disciplines of palliative care and mental health was found woefully lacking. In addition, education for nurses specific to abortion care was ad-hoc, fragmented and relied mostly on informal peer teaching from other nurses.

The key recommendations emanating from the study were that consideration should be given to developing structures, processes and training to support nurses in their practice with a view to maintaining high quality patient care. Training for staff should be evidence-based, patient centric, planned and a priority and not rely primarily on the good will of colleagues. It is envisaged that the findings of the study will provide a framework with which to build robust support structures for nurses working in this unique area of healthcare.
How Women's Roles In Local Politics Are Understood At The Commune Level: Beoung Preah Commune, Cambodia
Authors:   , Koy Sokunthea

Promoting women’s political participation aims to achieve gender equality and bring justice to women whose rights and choices have been constrained. Women all around the world have remained subordinated in politics, and this is still true today, from the local to the global level (Whitworth, 1994). For some women who participate in public political activities, their ability to gain leadership or primary positions has been restricted by many factors. Gender roles and gender stereotypes shape formal political structures in the same way that these factors shape a family’s structure (Lilja, 2008).

This qualitative study therefore, contributes to better understanding local perspectives on the roles of women in Cambodia’s local politics, either as voters or politicians in order to address gender inequality. This study will be an input for developing strategies which aim at engaging local people in gender equality programs which promote women’s participation in politics, and it will also contribute to the study of gender and politics in Cambodia. Based on Beoung Preah commune, Cambodia, this study drew on feminist epistemology and qualitative methodology. It involved the use of semi-structured interviews and focus groups with community members, political party representatives, local officials and other relevant local actors in Beoung Preah commune.

This study explores local understandings of women’s political opportunities and political representation, in which they believe to make change in their community. This discusses the reasons behind women’s underrepresentation in local politics and suggests steps forward, grounded in local participants’ knowledge. It investigated local discourses on gender stereotypes such as how research participants conceptualize femininities and masculinities constituting the ideal attributes of political leaders. This is important for understanding women and men’s political opportunities and constraints. The study also explored different local perspectives on women’s political representation, expectations, emerging outcomes and socio-economic and political challenges, which make gender inequality a more complicated issue to address in the commune context.

While achieving gender parity is in progress, the query of whether gender equality can be simply achieved right after women’s inclusion in local politics needs to be further investigated.
