Turgut Özal ve Yeni Kamu Yönetimi: 1983 – 1993 Arası Yıllarda Türkiye’de Kamu Yönetimi Reformu
Authors: BEKTAŞ Mücahit , ATEŞ Hamza
Published: December 2021

1980’li yıllar kamu yönetiminde büyük değişimlerin yaşandığı yıllar olmuştur. Bu çalışmada Türkiye’de yaşanan değişimler Turgut Özal’ın merkeze alındığı bir bakış açısıyla incelenmiştir. Çünkü Yeni Kamu Yönetimi reformlarının ağırlıklı olarak Özal’ın aktif olduğu yıllarda uygulamaya konulması ve onun vefatıyla da kesintiye uğraması, Özal’ın belirleyici bir aktör olduğunu göstermektedir. Çalışmada, Özal’ın, Yeni Kamu Yönetimi reformlarını Türkiye’nin ihtiyaçlarına göre yeniden şekillendirdiği ve bu yönüyle İngiltere ve Amerika gibi diğer ülkelerden önemli oranda farklılaştığı görülmüştür. Buradan yola çıkarak Yeni Kamu Yönetimi’nin her şeye uyan tek bir model dayatmadığı, ülkelerin kendilerine özgü ihtiyaçlarına göre reformları şekillendirebildiği anlaşılmaktadır. Bu iddiayı desteklemek için, Özal’ın uygulamaları ile Amerika ve İngiltere’de özelleştirme ve yerelleşme gibi belli başlı reform politikaları karşılaştırılmıştır. Sonuç olarak, yalnızca Türkiye ile değil, İngiltere ve Amerika’nın da kendi aralarında farklılaştıkları anlaşılmıştır.
La publicación por parte de los centros de arbitraje de laudos que no hayan sido impugnados
Authors: Bustamante Luna Francisco
Published: December 2021

La publicación de los laudos arbitrales como medida de transparencia y herramienta para estudio de casos análogos, enfrenta a una corriente de defensores de la tesis de que la confidencialidad del proceso arbitral se extiende inclusive a los laudos arbitrales. Las legislaciones y centros de arbitraje, que aprecian y defienden el deseo de las partes de mantener la reserva en los asuntos materia de controversia, han actuado cautelosamente en cuanto a la posibilidad de publicidad. No han dejado de reconocer los argumentos a favor de esta y algunos centros arbitrales de prestigio han efectuado reformas a sus normas y reglamentos para regular con condicionamientos la mencionada publicidad. En general, se debe cumplir exigentes requisitos concretos para que esto ocurra. Este artículo busca dar algunos antecedentes y orientaciones, a fin de que en el Ecuador se encuentre un equilibrio en las medidas que deben tomar los centros para resolver el problema, robusteciendo el mecanismo arbitral a tono con los tiempos.

Nowadays, the effect of the rare earth addition on the performance of aluminium matrix composites is a major interest for many researchers. The present research work emphasis is on the study of the effect of praseodymium oxide (rare earth element) addition on the performance of AA6351 hybrid composites. Silicon carbide and rice husk ash in the weight proportions of 6:2 were ball-milled with various weight percentages (0.4%, 0.8%, and 1.2%) of praseodymium oxide to have a consistent microstructure and combined density equivalent to the AA6351 matrix alloy. Further, AA6351 hybrid composites with the ball-milled reinforcement of silicon carbide, rice husk ash, and praseodymium oxide were produced using stir-casting technique. Physical, microstructural, mechanical, and tribological characterization were done to study the impact of praseodymium oxide addition on the developed hybrid composites. An increment of 2.61% in the density, 49.40% in the microhardness, and 19.78% in the ultimate tensile strength was recorded with the incorporation of 1.2 weight percentage of praseodymium oxide in the AA6351 hybrid composites. The wear rate of the developed composites also improved by 32.92% with the addition of praseodymium oxide. The results exhibited a remarkable improvement in the performance of the AA6351 hybrid composites with the addition of rare earth element.

Self-Adaptation Driven by SysML and Goal Models -- A Literature Review
Authors: Anda Amal Ahmed , Amyot Daniel
Published: December 2021

Background: Socio-cyber-physical systems (SCPSs) are a type of cyber-physical systems with social concerns. Many SCPSs, such as smart homes, must be able to adapt to reach an optimal symbiosis with users and their contexts. The Systems Modeling Language (SysML) is frequently used to specify ordinary CPSs, whereas goal modeling is a requirements engineering approach used to describe and reason about social concerns.

Objective: This paper aims to assess existing modeling techniques that support adaptation in SCPSs, and in particular those that integrate SysML with goal modeling.

Method: A systematic literature review presents the main contributions of 52 English articles selected from five databases that use both SysML and goal models (17 techniques), SysML models only (11 techniques), or goal models only (8 techniques) for analysis and self-adaptation.

Result: Existing techniques have provided increasingly better modeling support for adaptation in a SCPS context, but overall analysis support remains weak. The techniques that combine SysML and goal modeling offer interesting benefits by tracing goals to SysML (requirements) diagrams and influencing the generation of predefined adaptation strategies for expected contexts, but few target adaptation explicitly and most still suffer from a partial coverage of important goal modeling concepts and of traceability management issues.

Authors: Kaur Rajdeep , Chahal Kuljit Kaur , Saini Munish
Published: December 2021

Background: In the open source software paradigm, software development depends upon efforts of volunteer members that are geographically dispersed and collaborate with each other over the Internet. Communication artifacts like mailing lists, forums, and issue tracking systems are used by developers for communication. The way they express themselves through these communication channels greatly influences their productivity, efficiency of development activities, and survival of the project as well. Therefore, it is essential to understand affective state of developersâ€™ contributions to make software engineering more effective.

Aim: This study examined commit logs of seven GitHub projects to analyze developersâ€™ sentiments. This study also investigated the relationship of developersâ€™ sentiments in commit logs with team size of project, type of change activity, and contribution volume.

Method: Sentiments of developers are calculated using SentiStrength-SE tool that is specialized in software engineering domain.

Results: Our findings revealed that the majority of sentiments conveyed by developers in commit logs were neutral. Furthermore, we found that team size, change activity, and commit contribution volume influenced sentiments conveyed in commit logs.

Conclusion: Our findings will help project managers to better understand developer sentiments while performing different software development tasks/activities. It will be beneficial in improving developer productivity and retention.
Hadis dalam Perspektif Hizbut Tahrir Indonesia (HTI)
Authors: Fahrudin Fahrudin
Published: December 2021

This article discusses the thoughts of Hizb ut -Tahrir (HT) on the hadith of the Prophet, especially in relation to the Khilafah. In HT's belief that the hadith of the Prophet related to the baiat and the caliphate is an Islamic teaching that must be fought for, because the Islamic caliphate system has been applied by the Prophet and the khulafaurasyidin and is a concrete proof of the welfare of human life and harmony experienced by society in his time because of upholding Islamic law in kaffah. To be able to describe how HT's view of the hadith, the author collected good literary data from the writings of Taqiyudin al Nabhani himself who was a central figure in the HT group and did not miss the thoughts of his followers or those who opposed HT's own thoughts. . After the author collected some of the necessary data, the author then read and analyzed the thought flow of Hizb ut -Tahrir. By using descriptive analytical methods that eventually produce conclusions based on the results of studies on existing data
Genetic variation is predominantly structured by geography rather than host in feather mites (Acariformes: Sarcoptiformes) associated with tanagers (Aves: Thraupidae) in Brazil
Authors: Pedroso Luiz Gustavo de A. , Klimov Pavel B. , Hernandes Fabio A.
Published: December 2021

Feather mites are the most common ectosymbionts on birds. These obligatory symbionts are mainly transmitted during their host’s parental care, which creates high host specificity. Due to this intimate relationship, it is thought that their geographic distribution is restricted by their host distribution, or that a host species harbors the same mite composition across its whole range. However, our knowledge regarding the geographic distribution of feather mites remains scarce, with only a few studies indicating disconnections between mite and host distributions, especially in widespread hosts. Here, we investigate the feather mites distribution on four tanager species, three widespread – Thraupis sayaca (L.), T. palmarum (Wied), and Stilpnia cayana (L.) from Northern and Southern Brazil; and the Amazonian T. episcopus (L.). Feather mites were identified using the molecular barcode marker COX-1 using K2P genetic distances. We found a strong genetic structure between Northern and Southern populations of tanagers of more than 10%, even among conspecific hosts. Therefore, the mite distribution on Brazilian tanagers is predominantly shaped by geography rather than by host species. These features in turn reflect historical horizontal transmissions among the hosts, suggesting a high potential for frequent host switches in these symbionts.

This study used a descriptive qualitativedesign.A total of twenty-seven students were interviewed in five focus-group discussions. Data wereanalysed using content analysis. Students identified three broad themes: hope offers emotional support,fostering individualised hope,and shared responsibility by the team. There was broad consensus amongthe students that fostering hope is an important aspect of providing emotional support to the patients. Thefindings indicate that nursing students are cognisant of the greater value of providing an individualisedhope for each patient. Simultaneously, the students recognise the value of shared responsibility bythe healthcare team to nurture hope in healthcare context.With these findings, it is recommended thatstudents receive further support to learn and be sensitive to the language of hope, given the importanceof hope in healthcare practice.

In this work we showcase the emitter DICzTRZ in which we employed a twin-emitter design of our previously reported material, ICzTRZ. This new system presented a red-shifted emission at 488 nm compared to that of ICzTRZ at 475 nm and showed a comparable photoluminescence quantum yield of 57.1% in a 20 wt % CzSi film versus 63.3% for ICzTRZ. The emitter was then incorporated within a solution-processed organic light-emitting diode that showed a maximum external quantum efficiency of 8.4%, with Commission Internationale de l’Éclairage coordinate of (0.22, 0.47), at 1 mA cm−2.

Purpose of the study. A retrospective analysis of the immediate results of performing anterior rectal resections in cancer.

Materials and methods. In the Department of Abdominal Oncology No. 1 with a group of X-ray vascular methods of diagnosis and treatment of the clinic of the National Medical Research Centre for Oncology of the Ministry of Health of Russia treatment for rectal cancer operations of anterior rectal resection were performed in 334 patients, while in 143 (42.8 %) cases they were low. As a standard, total mesenteric excision and lymphoid dissection in volume D2 were performed. Combined surgical interventions were performed in 68 (20.4 %) patients for locally spread tumors. As a rule, they were resection in nature and were performed with tumor infiltration of adjacent organs (bladder with ureters, ovaries, uterus, vagina, small intestine, abdominal wall). Colorectal anastomosis using crosslinking devices was formed in all cases, in 316 (94.6 %) cases it was a "side – to-end" junction, in 18 patients – "end-to-end". A preventive proximal intestinal stoma was formed in 73 (21.9 %) cases, where 67 cases it was an ileostomy, and 6 – a transversostomy. The preventive proximal intestinal stoma was not formed among 261 patients. Results. After performing anterior resections for rectal cancer operations, the complications developed in 75 (22.5 %) patients. The most threatening and dangerous complication was the failure of the colorectal anastomosis, which was noted in 12 (3.5 %) cases.This complication occurred in 8.2 % (6 patients out of 73) of preventatively stoma-treated patients, in 2.3 % of patients without a stoma (6 patients out of 261).Conclusion. The use of a preventive proximal intestinal stoma allows you to form a colorectal anastomosis even in the presence of complicated forms of rectal cancer. The number of complications directly referred to the formation of a preventive proximal intestinal stoma is relatively small, but when planning surgery for uncomplicated rectal cancer, the probability of their possible occurrence should be taken into account.
The use of transdermal therapeutic systems for chemical pleurodesis in a patient with prolonged air leakage after lung resection for cancer

This clinical observation demonstrates a method of a motivated use of a transdermal therapeutic system (TTS) based on fentanyl for chemical pleurodesis in a patient with prolonged air leakage after lung resection for cancer. The most common complication after elective lung resections is an alveolar-pleural fistula or prolonged air leakage. This clinical phenomenon occurs as a result of communication between the alveoli of the lung parenchyma distal to the segmental bronchus and the pleural cavity. In most cases, air leakage through the drains is eliminated spontaneously, but the frequency of prolonged pneumostasis absence in the postoperative period can reach 25 %, which has a negative effect on the outcomes of surgical interventions due to the development of pneumonia and empyema. Long-term drainage of the pleural cavity does not always end with aerostasis and requires repeated invasive interventions. One of the ways to achieve the tightness of the lung tissue involves various methods of chemical pleurodesis, which is a surgical manipulation – the introduction of a sclerosing chemical substance into the pleural cavity by spraying medical talc through a trocar or a injecting tetracycline solution into the pleural drains. The chemical causes aseptic inflammation and adhesions between the visceral and parietal pleura, followed by obliteration of the pleural cavity. The sclerosant introduction is accompanied by severe pain that can provoke respiratory and/or hemodynamic deficits, up to apnea and life-threatening heart rhythm disturbances. Pain relief during chemical pleurodesis is obviously an important factor in the prevention of a number of complications in patients undergoing surgery for lung cancer. Bolus intravenous injections of narcotic analgesics lead to an analgesic effect, but a short-term one due to the absence of a depot in the body and a sharp drop in the drug concentration in the blood serum. Unfortunately, this method of introducing narcotic drugs can cause various complications in weakened and elderly cancer patients, such as respiratory depression and cardiac arrest. The TTS action is characterized with continuous dosing and the creation of a constant concentration of the narcotic drug over a certain period of time. This method provides a multilevel and systematic approach to pain relief, reduces toxicity and minimizes the inhibition of the central mechanisms of external respiration regulation without causing respiratory and cardiac disorders in patients who underwent lung resection.

The relevance of the topic considered in the article lies in solving problematic issues of identifying rare events in imbalance conditions in training sets. The purpose of the study is to analyze the capabilities of a classifier’s ensemble trained on different imbalanced data subsets. The features of the heterogeneous segments state analysis of the Internet of Things network infrastructure based on machine learning methods are considered. The prerequisites for the unbalanced data emergence during the training samples formation are indicated. A solution based on the use of a classifier’s ensemble trained on various training samples with classified events imbalance is proposed. The possibility analysis of using unbalanced training sets for a classifier’s ensemble averaging of errors occurs due to the collective voting procedure, is given. An experiment was carried out using weak classifying algorithms. The estimation of features values distributions in test and training subsets is carried out. The classification results are obtained for the ensemble and each classifier separately. An imbalance is investigated consists in the events number ratios violation a certain type within one class in the training data subsets. The data absence in the training sample leads to an increase in the scatter effect responses is averaged by an increase in the model complexity including various classifying algorithms in its composition. The proposed approach can be applied in information security monitoring systems. A proposed solution feature is the ability to scale and combine it by adding new classifying algorithms. In the future, it is possible to make changes during operation to the classification algorithms composition, it makes possible to increase the indicators of the identifying accuracy of a potential destructive effect.
