O aumento do consumo desenfreado do plástico contribuiu para sua presença em grandes quantidades no lixo urbano. Uma alternativa para os problemas causados pelo descarte indevido desses resíduos seria a substituição dos plásticos tradicionais por polímeros biodegradáveis e de fontes renováveis cujo ciclo de vida tende a ser menos poluente, visto que, sob condições favoráveis, se degradam em ambientes biologicamente ativos, não produzindo rejeitos tóxicos para o ambiente. Visando esses benefícios, esse trabalho teve como objetivo a criação de um novo tipo de bioplástico proveniente de uma fonte não convencional de matéria prima, aGlircídia. As folhas da Gliricídia foram coletadas próximas a uma área experimental do IFRR/Campus Novo Paraíso, depois de obtidas, foram levadas ao Laboratório de Química e Biologia, as folhas foram lavadas com água corrente e água destilada para eliminar possíveis contaminações que comprometessem os processos da pesquisa. Para produção do bioplástico, foram realizados 10 testes contendo formulações diferentes. As misturas seguiram o mesmo processo de elaboração, cada material foi pesado de acordo com sua formulação, colocado em um bequer de 150 ml e misturados manualmente com auxílio de um bastão de vidro, depois de misturados os materiais seguiram para um agitador magnético com aquecimento para fervura da mistura por cerca de 15 minutos, para que fosse realizado a sintetização do biopolímero. Os materiais depois de prontos foram posto em placas de petri e colocados em estufa de circulação forçada a 65° C por um perído de 12 horas. Apesar de todas as diferentes formulações, apenas três obtiveram resultados promissores, sendo elas o formulação 1, formulação 3 e formulação 4, por outro lado, as formulações 1 e 4 apesar de não apresentarem características poliméricas, apresentaram consistência semelhante a de um papelão, assim como sua resistência a forças mecânicas e com um aspecto peculiar, podendo ser capazes de se expandir na presença de água e não degradar sua estrutura, retornando ao estado normal após perder toda umidade, estas características foram presentes em maior quantidade na formulação 1 que apresentou maior sensibilidade de absorção de água, por outro lado, a formulação 4 se mostrou quase que totalmente impermeável, porém com capacidades semelhantes a formulação 1 mas reduzidas se comparadas ao mesmo. Os materiais obtidos na pesquisa ainda que não sejam poliméricos podem ser aplicados em diferentes áreas da industrias, como em formas de compósitos na indústria automotiva ou como insumo de fortalecimento na estrutura de construções civis, os chamados compósitos.

Authors: Sreenivasulu Duggineni , Reddy N. Simhachalam , Sowjany J Lakshmi
Published: November 2023

In the present-day context, a considerable portion of the population faces the challenge of edentulism. Various treatment approaches, including both fixed and removable prostheses, are available for restoring missing teeth. Noteworthy progress has recentlybeen observed in the characteristics of commonly used dental materials, attributed to the emergence of nanotechnology. This technological advancement has significantly contributed to improving the outcomes of dental treatments. Nanotechnology represents amultidisciplinary domain that amalgamates principles from both the arts and sciences, involving the manipulation of structures and functional materials at a minuscule scale. This field leverages various physical and chemical methodologies to operate at dimensions where sizes of particles, typically ranging from 1 to 100 nanometers, give rise to what is termed as Nanoparticles. The integration of nanoparticles in dentistry, particularly within dental materials such as ceramics, acrylic resin, tissue conditioners, and denture adhesives, has exhibited a discernible positive impact on their inherent properties. This review predominantly delves into an exploration of diverse applications of nanoparticles within the realm of dentistry, with a specific emphasis ontheir role in prosthodontics.

Earlier treatments of Edward Prime-Stevenson’s
Left to Themselves
(1891) have performed the crucial tasks of arguing for its importance in literary history as well as examining some of its formal innovations. This article advances scholarship by attending to its treatment of places. In the novel, the young protagonists Philip Touchtone and Gerald Saxton embark on an eventful journey from New York to Halifax, Nova Scotia. Along the way, they encounter all sorts of perils from attempted kidnapping to actual shipwrecks. Philip’s and Gerald’s perceptions, and their engagements with space, we suggest, inform our understandings of them and of Stevenson’s social commentary. By analysing his project geographically, and with particular attention to a central episode that takes place in the fictional Chantico Island, this essay reveals how Stevenson turns to places to expose, to unsettle, and ultimately to (re)imagine social realities.
High-soft to Low-hard State Transition in Black Hole X-Ray Binaries with GRMHD Simulations
Authors: Dihingia Indu K. , Mizuno Yosuke , Sharma Prateek
Published: November 2023

To understand the decaying phase of outbursts in the black hole (BH) X-ray binaries (BH-XRBs), we performed very long general relativistic magnetohydrodynamic simulations of a geometrically thin accretion disk around a Kerr BH with slowly rotating matter injected from outside. We thoroughly studied the flow properties, dynamical behavior of the accretion rate, magnetic flux rate, and jet properties during the temporal evolution. Due to the interaction between the thin disk and injected matter, the accretion flow near the BH goes through different phases. The sequence of phases is: soft state → soft-intermediate state → hard-intermediate state → hard state → quiescent state. For the accretion rate (and hence the luminosity) to decrease (as observed) in our model, the mass injection should not decay slower than the angular momentum injection. We also observed quasiperiodic oscillations (QPOs) in the accretion flow. Throughout the evolution, we observed low-frequency QPOs (∼10 Hz) and high-frequency QPOs (∼200 Hz). Our simple unified accretion flow model for state transitions is able to describe outbursts in BH-XRBs.
A Database of Magnetic and Thermodynamic Properties of Confined and Eruptive Solar Flares
Authors: Kazachenko Maria D.
Published: November 2023

Solar flares sometimes lead to coronal mass ejections that directly affect Earth's environment. However, a large fraction of flares, including on solar-type stars, are confined flares. What are the differences in physical properties between confined and eruptive flares? For the first time, we quantify the thermodynamic and magnetic properties of hundreds of confined and eruptive flares of GOES class C5.0 and above, 480 flares in total. We first analyze large flares of GOES class M1.0 and above observed by the Solar Dynamics Observatory, 216 flares in total, including 103 eruptive and 113 confined flares, from 2010 until 2016 April; we then look at the entire data set of 480 flares above class C5.0. We compare GOES X-ray thermodynamic flare properties, including peak temperature and emission measure, and active-region (AR) and flare-ribbon magnetic field properties, including reconnected magnetic flux and peak reconnection rate. We find that for fixed peak X-ray flux, confined and eruptive flares have similar reconnection fluxes; however, for fixed peak X-ray flux confined flares have on average larger peak magnetic reconnection rates, are more compact, and occur in larger ARs than eruptive flares. These findings suggest that confined flares are caused by reconnection between more compact, stronger, lower-lying magnetic fields in larger ARs that reorganizes a smaller fraction of these regions’ fields. This reconnection proceeds at faster rates and ends earlier, potentially leading to more efficient flare particle acceleration in confined flares.
Expanding Leadership and Professional Development Opportunities for Oncology Nurse Practitioners
Authors: Triglianos Tammy , Tan Kelly R. , Prewitt Judy , Fajardo Marco , Hirschey Rachel
Published: November 2023

Nurse practitioner (NP) involvement in professional organizations improves clinical practice, patient outcomes, and health care policy. Results of a survey for a local professional nursing organization showed a need for more NP-level education and NP mentorship and leadership training. Findings were applied to develop a leadership initiative through an NP-led continuing education program. At the conclusion of the program, NP presenters completed a survey. The NP presenters agreed that participating in this program and the mentoring that was provided helped them prepare for their sessions, improve their leadership skills, and prepare for additional speaking engagements. Additionally, each session's attendees completed evaluation surveys. Results from program attendees indicated a high level of agreement about meeting learning objectives in sessions and the effectiveness of the NP presenters. This innovative program may be modeled across a variety of nursing specialties, settings, and organizations to enhance NP professional development and support nursing-led continuing education.

DlncRNALoc: A discrete wavelet transform-based model for predicting lncRNA subcellular localization
Authors: Fu Xiangzheng , Chen Yifan , Tian Sha
Published: November 2023

The prediction of long non-coding RNA (lncRNA) subcellular localization is essential to the understanding of its function and involvement in cellular regulation. Traditional biological experimental methods are costly and time-consuming, making computational methods the preferred approach for predicting lncRNA subcellular localization (LSL). However, existing computational methods have limitations due to the structural characteristics of lncRNAs and the uneven distribution of data across subcellular compartments. We propose a discrete wavelet transform (DWT)-based model for predicting LSL, called DlncRNALoc. We construct a physicochemical property matrix of a 2-tuple bases based on lncRNA sequences, and we introduce a DWT lncRNA feature extraction method. We use the Synthetic Minority Over-sampling Technique (SMOTE) for oversampling and the local fisher discriminant analysis (LFDA) algorithm to optimize feature information. The optimized feature vectors are fed into support vector machine (SVM) to construct a predictive model. DlncRNALoc has been applied for a five-fold cross-validation on the three sets of benchmark datasets. Extensive experiments have demonstrated the superiority and effectiveness of the DlncRNALoc model in predicting LSL.
Impulsive control for stationary oscillation of nonlinear delay systems and applications
Authors: Li Shipeng
Published: November 2023

In this paper, the problem of existence-uniqueness and global exponential stability of periodic solution (i.e., stationary oscillation) for a class of nonlinear delay systems with impulses was studied. Some new sufficient conditions ensuring the existence of stationary oscillation for the addressed equations were derived by using the inequality technique that has been reported in recent publications. Our proposed method, which is different with the existing results in the literature, shows that nonlinear delay systems may admit a stationary oscillation using proper impulsive control strategies even if it was originally unstable or divergent. As an application, we considered the single species logarithmic population model and established a new criterion to guarantee the existence of positive stationary oscillation. Some numerical examples and their computer simulations were also given at the end of this paper to show the effectiveness of our development control method.

This paper aims to present the findings for the use of educational digital games in the field of special education and specifically in the education of people with autism spectrum disorder (ASD).
Accompagner les initiatives citoyennes dans le cadre d’un projet de revitalisation d’une commune rurale : le cas de Volonne
Authors: Bonnin-Oliveira Séverine , Hatt Emeline
Published: November 2023

Cet article traite de la recomposition des relations entre acteurs publics et citoyens dans la définition et la conduite de projets d’urbanisme durable en milieu rural, à partir de l’analyse du cas de Volonne (Alpes-de-Haute-Provence). Dans une forme de prolongement de la dynamique participative initiée lors de la création de l’EcoQuartier centre-bourg (labellisé étape 4 par le Ministère), alliant des dispositifs de consultation, de concertation et de co-construction, cette commune rurale a vu l’émergence d’un engagement citoyen multiforme étudié dans cette recherche. Nous questionnons dans cette perspective la capacité des communes rurales à accompagner et pérenniser les initiatives citoyennes dans ces démarches visant la transformation du cadre bâti et le développement du « vivre ensemble » dans les espaces ruraux. La recherche a mis en lumière la diversité des initiatives citoyennes et leur participation à l’amélioration du cadre de vie mais aussi la nécessaire modification des cadres d’action publique traditionnels. L’association entre acteurs publics et citoyens appelle des ajustements, des articulations qui restent pour partie à trouver pour répondre aux difficultés de coordination ou au risque de resserrement des initiatives autour d’un groupe restreint de participants.
Remote Sensing Image Semantic Segmentation Method Based on a Deep Convolutional Neural Network and Multiscale Feature Fusion
Authors: Zhang Guangzhen , Jiang Wangyang
Published: November 2023

There are many problems with remote sensing images, such as large data scales, complex illumination conditions, occlusion, and dense targets. The existing semantic segmentation methods for remote sensing images are not accurate enough for small and irregular target segmentation results, and the edge extraction results are poor. The authors propose a remote sensing image segmentation method based on a DCNN and multiscale feature fusion. Firstly, an end-to-end remote sensing image segmentation model using complete residual connection and multiscale feature fusion was designed based on a deep convolutional encoder–decoder network. Secondly, weighted high-level features were obtained using an attention mechanism, which better preserved the edges, texture, and other information of remote sensing images. The experimental results on ISPRS Potsdam and Urban Drone datasets show that compared with the comparison methods, this method has better segmentation effect on small and irregular objects and achieves the best segmentation performance while ensuring the computation speed.
The Changing Pattern of Housing in India with Special Reference to Chandigarh
Authors: Chaudhary Archana
Published: November 2023

The housing scenario in the world over and more particularly in the developing countries like India is undergoing a major change. India's urban population is currently around 30% of its total population. Experience across the world has been that as the economies grow; rapid urbanization takes this proportion to over 60% before it begins to stabilize. As such, it is projected that India's urban population would grow to about 473 million in 2021 and 820 million by 2051, as against only 285 million in 2001. This paper presents the housing scenario with special reference to Chandigarh which is called the Mecca of Architects. It has witnessed an enormous change in the pattern of housing due to various reasons well understood and a part of normal phenomenon. Due to scarcity ofland and population explosion, there is a steep rise in the height of buildings and the design of houses has also changed.
Revisiting Conservative Surgery: Urban Conservation and Living City
Authors: Munasinghe Harsha
Published: November 2023

City becomes conservation-worthy by being a cultural setting. Heritage city, once conserved, shall facilitate the continuous evolution of the city culture. Traditio11ally, urban conservation was considered as preserving the physical fabric of a few monumental structures of a city, representing either a building type or an architect. This, compartmentalising the urban space, turning it in to an open-air museum, and replacing some sub-societies with more influential ones, did not facilitate the continuity of the unified image of the city. The result has been the degradation of city life. Our research proposition for urban conservation is to strengthen the container-quality of urban space by protecting the unique image which facilitates dwelling in the city. We interpret urban conservation as strengthening the container quality of urban space by achieving the equilibrium between continuity of heritage values and change ofliving needs. Similar ideas in the works of Sir Patrick Geddes and his disciples can be found. His concept, conservative surgery, guides us to see such equilibrium between change and continuity. This paper, based on a literature review, attempts to revisit this concept.

Authors: Lakmini Balagamage Chamila , Ratnayake Himali Erandathie , Atapattu Navoda
Published: November 2023

Background: The clinical presentation of hypopituitarism varies from asymptomatic to circulatory compromise. The late diagnosis may cause significant mortality and morbidity. There is scant data on the clinical profile.Method: A cross-sectional descriptive analysis was carried out on diagnosed children with hypopituitarism at the endocrinology unit of Lady Ridgeway Hospital for Children, Sri Lanka, from 2013-2021. The presence and progression of pituitary hormonal deficiency were ascertained.Results: Out of the total 94 children with hypopituitarism, 52 had congenital hypopituitarism with a median presenting age of 5.86 years (IQR 3-9). Short stature was the commonest presentation (59.6%). Multiple pituitary hormone deficiency (MPHD) was seen in 27 (51.91%). MPHD was associated with the presence of postnatal risk factors (OR 2.036, 95% CI 1.94-3.786) and MRI Imaging abnormalities in hypothalamic-pituitary morphogenesis (OR 1.768, 95% CI 1.087-2.874). 90.4% with GHD, 46.2% with ACTH deficiency, and 40.4% with TSH deficiency had the mean age of presentation 6.54 years, 6.11 years, and 5.56 years respectively. Of the children above 13 years, 57% showed hypogonadism. Hypoplastic anterior pituitary (40.4%) was the commonest MRI abnormality. Out of the 42 children with brain tumours, 25 (59.52%) had craniopharyngioma, and 13 (31%) had Medulloblastoma, while MPHD was seen in 32 (76.2%). Hormone deficiency at the presentation was seen in 57.1%.Conclusion: Comprehensive evaluation and periodic screening are mandatory for the timely diagnosis of MPHD.

Many children experienced anxiety during their initial dental visits, often fearing medical equipment and the procedures they would undergo. The Dental Explosion Box served as an alternative approach to enhance oral health awareness and functioned as an educational tool integrated with a game. This study aimed to assess the effectiveness of the Dental Explosion Box in introducing oral health concepts to early childhood. This research employed a pre-experimental design featuring a one-group pre-test and post-test approach. Sampling relied on the purposive sampling technique, with the sample size determined using the Isaac and Michael formula, resulting in a cohort of 25 preschool students. Variables examined in this study encompassed the Dental Explosion Box and Oral health Awareness. Oral health awareness in preschool children was measured using a checklist of questions. The Dental Explosion Box had undergone rigorous testing and had been endorsed by media and material experts. The study's hypotheses were tested using the Wilcoxon Sign Rank Test. The average pre-intervention oral health introduction score was 6.68, while the post-intervention score increased to 11.00. Analysis through the Wilcoxon Sign Rank Test revealed a significant difference (p-value of 0.000, <0.05) between the level of oral health awareness in early childhood before and after receiving intervention with the Dental Explosion Box. The findings from this study highlighted the effectiveness of the Dental Explosion Box in introducing oral health concepts to early childhood. It enhanced children's familiarity with oral health and motivated them to regularly visit the dentist.

Authors: Alkhayal Abdullah , Aljumaiah Sahar , Alyami Ali , Abumelha Saad , Alrabeeah Khalid
Published: November 2023

Background:

Varicocele is a reversible cause of male infertility. However, there are conflicting data available concerning the benefit of varicocele repair for patients with nonobstructive azoospermia (NOA) and severe oligoasthenoteratozoospermia (OAT).

Objective:

To address the benefit of varicocelectomy in patients with severe OAT and NOA with regard to their semen parameters and surgical sperm retrieval rate in those who underwent testicular sperm extraction (TESE) or testicular sperm aspiration (TESA).

Materials and Methods:

This retrospective cohort study was conducted on a sample of 13 patients diagnosed with NOA and severe OAT who underwent varicocelectomy for infertility treatment with no prespecified exclusion criteria.

Results:

Thirteen patients were enrolled. Five patients were diagnosed with NOA; eight were diagnosed with severe OAT. For improvements in the semen parameters postoperatively, the semen concentration of all patients was significantly increased compared to the preoperative concentration (3.59 ± 10.0.8 vs. 0.25 ± 0.31, P = 0.02) and the remaining parameters were unchanged. Regarding sperm retrieval, three patients underwent TESE and two patients underwent TESA, in which all had positive results.

Conclusion:

Varicocele repair was found to improve the semen parameters in patients with NOA and severe OAT and produced a successful surgical sperm retrieval rate in all patients who underwent TESA or TESE.
Singular orthotropic functionals with nonstandard growth conditions
Authors: Bousquet Pierre , Brasco Lorenzo , Leone Chiara
Published: November 2023

We pursue the study of a model convex functional with orthotropic structure and nonstandard growth conditions, this time focusing on the sub-quadratic case. We prove that bounded local minimizers are locally Lipschitz. No restrictions on the ratio between the highest and the lowest growth rates are needed. The result holds also in presence of a non-autonomous lower order term, under sharp integrability assumptions. Finally, we prove higher differentiability of bounded local minimizers as well.
Performance Analysis of Cooperative Truck Platooning under Commercial
Operation during Canadian Winter Season
Authors: Jiang Luo , Kheyrollahi Javad , Koch Charles Robert , Shahbakhti Mahdi
Published: November 2023

The cooperative platoon of multiple trucks with definite proximity has the
potential to enhance traffic safety, improve roadway capacity, and reduce fuel
consumption of the platoon. To investigate the truck platooning performance in a
real-world environment, two Peterbilt class-8 trucks equipped with cooperative
truck platooning systems (CTPS) were deployed to conduct the first-of-its-kind
on-road commercial trial in Canada. A total of 41 CTPS trips were carried out on
Alberta Highway 2 between Calgary and Edmonton during the winter season in 2022,
25 of which were platooning trips with 3 to 5 sec time gaps. The platooning
trips were performed at ambient temperatures from −24 to 8°C, and the total
truck weights ranged from 16 to 39 tons. The experimental results show that the
average time gap error was 0.8 sec for all the platooning trips, and the trips
with the commanded time gap of 5 sec generally had the highest variations. The
average number of disengagements increased when the time gap rose from 3 to 5
sec, and the average engagement distance of all platooning trips was 1.92 km. In
the review of the platooning effect on the powertrain system, it was observed
that fluctuations in the follower truck’s engine power were generally larger
compared to those of the lead truck. Furthermore, when trucks performed
platooning on the flat road segments, the follower truck saved fuel; however, on
the road segments with grade changes, the freight transportation specific fuel
consumption (kg/(ton·100 km)) of the follower truck increased. Moreover, the
freight transportation specific fuel consumption of the follower truck was 25.8%
more than that of the lead truck when cut-ins and cut-outs occurred. Test
results show that the frequency of cut-ins increased from 1.6 to 5 times per
hour when time gap increased from 3 to 5 sec. Overall, beyond successful and
safe commercial truck platooning operations during the cold winter season, no
substantial benefit of fuel saving was observed in the investigated
platform.
Age-related changes in hormonal profiles and testicular diameter of West African Dwarf buck treated with gonadotropin-releasing hormone
Authors: Oruene I.S. , Mutembei H.M. , Kipyegon A.N.
Published: November 2023

This study aimed to investigate the impact of age-related peripheral and Gonadotropin Releasing Hormone (GnRH)  -stimulated hormonal profiles on testicular size in West African dwarf bucks. Twelve 3-month-old bucks were randomly  divided into two groups: the GnRH- treated group (n = 6) and the control group (n = 6). Over the course of 10 months,  from month 3 to month 12, the testicular diameter of all bucks was measured monthly, and blood samples were  collected monthly for hormone analysis. The results showed that testicular diameter increased with age and higher  concentrations of Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) and Testosterone (T). The GnRHtreated  group reached its peak testicular diameter (28.36±1.44 mm) earlier at 8 months compared to the control group  (30.50±1.44 mm) at 10 months, aligning with the peak concentrations of FSH, LH, and T. While the GnRH stimulation led  to higher FSH, LH, T, and estrogen levels in the treated group, it didn't significantly affect the final testicular diameter  (p<0.05). It can be concluded that hormonal levels rise with age and increasing testicular size, and GnRH stimulation can  accelerate this process. Testicular size is an important factor in breeding soundness and is influenced by LH, FSH, and  testosterone concentrations. These hormones can reliably indicate the reproductive capacity of the buck. Therefore,  hormonal profiling should be an integral part of the breeding soundness examination.

The Law On Human Trafficking For The Purpose Of Illegal Organ Trade
Authors: Sinaga Hasudungan
Published: November 2023

The merits and drawbacks of organ sales are vigorously debated in Indonesia. Nevertheless, some argue that the trade in human organs should be prohibited, a stance supported by Indonesian law. Both organ recipients and donors bear significant responsibility in organ trade, as financial gain serves as the primary motive for organ brokers and medical professionals alike. This research aims to conduct a Legal Analysis of Human Trafficking for the Purpose of Organ Illegal Trade. The methodology employed is a literature review through online searches on various journal platforms such as Google Scholar, Science Direct, and the Garuda Portal, focusing on national and international scientific journal articles. The search, limited to the last four years (2019-2023), employed subject-specific terms like "human organ trafficking," "person trafficking," or "positive law." The search excluded articles containing only conceptual discussions. The findings reveal that the buying and selling of organs are ethically reprehensible and illegal in the healthcare industry, as outlined in Health Law Number 36 of 2009. Although ethical kidney transplants using organs obtained through sales are impossible, specific considerations should be noted. The purchase and sale of human organs and/or biological tissue constitute a specialized crime, with Article 192 of Law Number 36 of 2009 specifying criminal punishments. Those found deliberately engaging in organ or body tissue trade, as defined in Article 64 paragraph (3), may face a maximum sentence of 10 years in prison and a fine of IDR 1,000,000,000 (one billion rupiah).

Authors: Hermawan Doni , Sukoyo Joko
Published: November 2023

This research examines the factors that hinder the implementation of Macapat song learning in junior high schools. This research used a descriptive qualitative approach. Data collection techniques in this research used observation, interview, and documentation techniques. The data was collected and analyzed using data analysis by Miles and Huberman (1994), which began with data collection, data reduction, data presentation, and conclusion. The validity of the data used the triangulation data method. The research results show that the implementation of Macapat song learning in junior high school is hampered by two factors: internal and external factors originating from students and teachers. The internal factors inhibiting students include low student interest, students' lack of mastery of Javanese vocabulary, and the assumption that learning Macapat songs is less critical. The internal factors inhibiting teachers include Javanese language teachers who tend not to have a Javanese language educational background, teachers who do not master the material of Macapat songs, less innovative learning methods, and teachers who have difficulty implementing the emancipated curriculum in learning. The external factors inhibiting students include device usage factors, family factors, and inadequate internet networks. The external factors inhibiting teachers include insufficient allocation of learning hours and lack of infrastructure that supports Macapat song learning. This research expects students to grow their interest in learning Macapat songs to maintain and preserve Javanese culture. With students' seriousness towards the Macapat song learning material, students will have a sense of love for Indonesian culture.
Effects of Employment Training Program on the well-being of the disabled persons-Evidence from China

Increasing the employment opportunities and income for the disabled persons are both important to safeguard the economic and social rights of this vulnerable groups, and to build an inclusive society. The goals are challenging to achieve because of: 1) the mismatch between economic structure and the education and training system for the disabled persons; 2) incoherent designing and ineffective implementation of various welfare programs for the disabled persons (赖德胜等 2008); 3) discriminatory attitude and practices by employers; 5) ineffective design and delivery of employment training programs (England 2003; Kulkami and Kote 2013).

Investigating the effects of government employment training programs enables us to identify the factors that contribute to the increase of the disabled persons’ income, and to provide evidence for policymakers to improve the training programs in order to realize the aforementioned goals.

The study is based on a large size sample questionnaire survey conducted in June-October 2018. The questionnaire is disseminated through an online website to the disabled persons’ mobile app Wechat. The respondents are located in 31 provincial administrative areas, and received 11296 responses. The questionnaire collects information about the characteristics of employment training programs delivered by the agencies, the respondents’ employment training experiences and training needs, their attitude towards the content, facilities and effects of the programs, the status of their employment, and their personal characteristics such as age, gender, education, income level, household registration status, and types and degree of disability. We also collect statistics that reflect the differences in terms of economic development and public service expenditure across provinces and regions. We use the linear regression model to test the effects of all these factors on the capability of the respondents to use the skills learned from the training programs to increase their income. The study concludes that the respondents are more likely to increase their income through training programs when the training content fits their jobs more, when they aim to develop interests and hobbies through training, and when they are more masterful of the training content. Different from many studies on the effect of performance management on job training performance, the findings suggest that responsive design and effective performance management of the training programs matter for positive program performance (Gerrish 2016). The study will also link with and contribute to the literature on social equity and employment policy for disabled persons that are rarely researched in public administration (e.g. Lindsay, Adams, McDougall and Sanford 2012; Gooden 2015).
5G and Public Management
Authors: Xue Lei
Published: November 2023

The emerging information and communication technology represented by 5G technology will have a profound and extensive impact on the social economy and public management. Based on the characteristics of 5G technology and a large number of concrete cases in real life, this paper holds that the application of 5G technology provides new means for the supply of public management, promotes the transformation of the comprehensive social governance model, builds an online power operation mechanism and thus provides strong support for improving the transparency of supervision and regulating the operation of power. At the same time, the application of 5G technology also presents certain challenges to public management, especially the lack of normative constraints in the process of public management, risks of an “information-isolated island” effect ,information security problems in the process of communication and sharing, and lack of operative technology and understanding of 5G technology application. In the conclusion, this paper argues that the public management body should fully recognise and evaluate the opportunities and challenges brought by 5G technology, make full use of its advantages, and make full preparations for its potential risks and challenges.
Parlamenter Sistemde Askeri Muhtıranın Etkisi Üzerine TBMM 1971-1980 Dönemi
Authors: BAKIRCI Fahri
Published: November 2023

Bu makalede 12 Mart 1971 tarihinde verilen Askeri Muhtıra’dan 12 Eylül 1980 Askeri Darbesi ile sonlanan dönemdeki siyasal krizlerin nedeni araştırılmakta ve bu krizlerin parlamenter sistemin işleyişiyle bir ilişkisinin bulunmadığı gösterilmeye çalışılmaktadır. Bu amaca ulaşmak için dönemi toptancı bir anlayışla incelemek yerine alt bölümler halinde bir çözümleme yapılmaktadır. Bu yolla herbir alt dönemin özgüllüğü ortaya konmakta ve her bir alt dönemde yaşanan siyasal krizlerin farklı nedenden kaynaklandığı gösterilmektedir. Böylece 2017 Anayasa değişikliğinin gerekçesi olarak kullanılan parlamenter sistem= siyasal kriz eşitliğinin her bir alt dönem için farklı bir nedenle geçerli olmadığı 1960-1971 dönemi için gösterilmiş olmaktadır.
