Influence of processing variables on quality of unsaturated polyester/E-glass fiber composites manufactured by double-bag progressive compression method
Authors: Chang Chih-Yuan , Chen Wei-Ru
Published: September 2018

A hybrid process of articulated resin transfer molding and vacuum-assisted resin infusion, called double-bag progressive compression method, has been invented to fabricate composite parts. In double-bag progressive compression method, the secondary bag is divided into several segments. During resin infusion, the double bag is drawn upward by vacuum, and the initial flow resistance offered by the loose preform is low. Once the resin infusion is completed, the vacuum on the segmented bags is progressively released to ambient pressure, and the segmental compression is sequentially performed until unnecessary resin is completely removed. This research is to experimentally investigate the influence of double-bag progressive compression method processing parameters, including vacuum pressure in the cavity, number of segments, initiating time of the next compression, temperature of the heated air, initiating segment of the heated air, initial height of the mold cavity, and excess infused resin, on the mechanical property of the part. The design of experiments adopts Taguchi’s method. Results show that the double-bag progressive compression method significantly reduces total filling time and maximally increases the flexural modulus of the part by 17.81% as compared with the typical vacuum-assisted resin infusion. A preferable parameter condition is proposed by taking both the flexural modulus and the operation complexity into account.

Objective

Patients with critical limb ischemia have serious systemic comorbidities and are at high risk of impairment of limb function. In this study, we assessed the prognostic factors of limbs after revascularization.

Methods

In this retrospective single-center cohort study, from April 2008 to December 2012, we treated 154 limbs of 121 patients with critical limb ischemia by the endovascular therapy-first approach based on the patients’ characteristics. The primary end point was amputation-free survival. Secondary end points were patency of a revascularized artery, major adverse limb events, or death. Furthermore, we investigated the ambulatory status one year after revascularization as prognosis of limb function.

Results

Endovascular therapy was performed in 85 limbs in 65 patients as the initial therapy (endovascular therapy group) and surgical reconstructive procedures (bypass group) were performed in 69 limbs in 56 patients. Early mortality within 30 days was not observed in either group. The primary patency rate was significantly better in the bypass group than in the endovascular therapy group ( p < 0.0001). Furthermore, the secondary patency rate was similar between the two groups ( p = 0.0096). There were no significant differences in amputation-free survival and major adverse limb event between the two groups. Univariate analysis showed that ulcer healing ( p < 0.0001), no hypoalbuminemia ( p = 0.0019), restoration of direct flow below the ankle ( p = 0.0219), no previous cerebrovascular disease ( p = 0.0389), and Rutherford 4 ( p = 0.0469) were predictive factors for preservation of ambulatory status one year after revascularization. In multivariate analysis, ulcer healing ( p < 0.0001) and restoration of direct flow below the ankle ( p = 0.0060) were significant predictors.

Conclusions

Ulcer healing and restoration of direct flow below the ankle are independently associated with prognosis of limb functions in patients who undergo infrainguinal arterial reconstruction.
Assessing the institutional learning curve for pararenal aortic repair using the fenestrated Anaconda endograft

Published: September 2018

Objective

Custom-made fenestrated aortic endografts allow exclusion of pararenal aortic aneurysms while maintaining blood flow to aortic branches. Meticulous device planning and precise deployment of the main body are essential to allow successful cannulation of the fenestrations. This study investigates whether a learning curve can be observed with more reliable cannulation and connection of fenestrations over time at a single department of vascular and endovascular surgery with multiple surgeons trained to use the device.

Methods

A retrospective analysis of data from all patients undergoing primary fenestrated endovascular aneurysm repair during the study period was performed. Outcome measures included case volume and average number of fenestrations over time, average fluoroscopy dose area product per calendar year and primary unconnected fenestration and 30-day mortality rates.

Results

Between 1 January 2013 and 31 December 2016, 89 patients with no history of endovascular aneurysm repair underwent fenestrated endovascular aneurysm repair at our institution. The number of fenestrations per case increased over time, averaging 2.6 in 2013 and 3.3 in 2016. Primary unconnected fenestration and 30-day mortality rates were 5.6%. Primary-assisted technical success was 93.3%, secondary-assisted technical success was 94.4%. Fluoroscopy dose area product declined over the study period. Thirty-day mortality and primary unconnected fenestration rates did not significantly change over the study period.

Conclusion

Albeit the reduction in lethal complications and primary technical success rates were not statistically significant, a lower percentage of unconnected fenestrations and 30-day mortality per calendar year were observed over time. At the same time, an increasing complexity of performed cases, as reflected by an increasing number of fenestrations per case, was observed. Complications associated with this complex endovascular procedure are potentially lethal and remain an unfortunate reality and may not be entirely dependent on overcoming a learning curve. A higher volume of cases performed over the study period and a reduction in fluoroscopy use can be considered a representation of the institutional development and learning curve for the Anaconda fenestrated endograft at a department with prior complex endovascular aortic repair experience, but due to limitations of the current retrospective observation, deserve further consideration in future trials, ideally designed in a prospective fashion.

Published: September 2018

Objective

Carotid stenosis with crescendo-transient-ischemic-attack (cTIA) requires a prompt intervention to reduce the stroke risk. Few data are reported in literature about cTIA suggesting a different perioperative risk compared with patients with single TIA (sTIA). This study aimed to compare the outcome of carotid endarterectomy (CEA) in patients with TIA (single/crescendo) and evaluate the outcome risk-factors.

Methods

Data from two tertiary hospitals for vascular treatment were analyzed from 2007 to 2016. All patients with TIA subjected to CEA were considered, comparing the 30-day postoperative stroke and stroke/death in patients with cTIA and sTIA, particularly in the urgent (≤48 h) setting.

Results

On a total of 3866 CEA, 888 (23%) were performed in symptomatic patients and 515 for TIA: 365 (71%) patients with sTIA and 150 (29%) with cTIA. When compared with sTIA, cTIA patients were younger and less frequently affected by coronary disease, dyslipidemia, and chronic pulmonary disease; however, contralateral carotid occlusion was more common (20% vs. 10%, P = .004; 56% vs. 46, P = .03; 16% vs. 7%, P = .01; >80 years 26% vs. 16%, P = .01 and 2% vs. 10%, P = .001; respectively). Postoperative stroke and stroke/death were significantly higher in cTIA compared with sTIA (5.3% vs. 1.6%, P = .02 and 6.0% vs. 2.2%, P = .03; respectively). Urgent CEA was performed in 58% ( n: 87) cTIA and in 11% ( n: 56) sTIA( P<.01). The urgent setting did not influence the stroke and stroke/death rate of CEA for sTIA (3.6% vs. 1.3%, P = .21 and 3.6% vs. 1.9%, P = .44, respectively), but was associated with lower rate of events in cTIA (1.1%vs. 11.1%, P = .01 and 2.3% vs. 11.1%, P = .03, respectively). This beneficial effect in patients with cTIA treated within 48-h was confirmed also by multivariate analysis (OR: 0.09, 95% CI: 0.76–0.01, P=.02).

Conclusions

cTIA subjected to CEA have a higher stroke and stroke/death risk compared with patients with sTIA. The urgent setting seems to reduce the stroke/death rate cTIA; for sTIA with a stable neurological condition, the timing of CEA did not influence the outcome.
Parallel multibody separation simulation using MPI and OpenMP with communication optimization
Authors: Ma Wenpeng , Hu Xiaodong , Liu Xiazhen
Published: September 2018

In this paper we investigate parallel implementations of multibody separation simulation using a hybrid of message passing interface and OpenMP. We propose a mesh block-based overset communication optimization algorithm. After presenting details of local data structures, we present our strategy for parallelizing both the overset mesh assembler and the flow solver by employing message passing interface and OpenMP. Experimental results show that the mesh block-based overset communication optimization algorithm has an advantage in real elapsed time when compared to a process-based implementation. The hybrid version shows that it is suitable for improving the load balance if a large number of CPU cores are used. We report results for a standard multibody separation case.
Toxoplasma gondii profilin does not stimulate an innate immune response through bovine or human TLR5
Authors: Tombácz Kata , Burgess Gregg , Holder Angela , Werners Arno , Werling Dirk
Published: September 2018

Toxoplasma gondii is responsible for one of the most prevalent infections in people. T. gondii profilin (TgPr) is a protein integral to parasite movement and cellular invasion. Murine TLRs has been described to bind TgPr. Furthermore, more recently, human TLR5 has been described to recognise recombinant TgPr, as well as bacterial flagellin. In addition to infections in humans, T. gondii infects farm animals, but little information is available about its innate recognition. We aimed to investigate whether, similarly to their human orthologue, bovine and porcine TLR5 could also be stimulated by TgPr by using a combination of reporter cell lines expressing full length TLR5 from each species as well as primary cells. Although human and bovine TLR5-transfected cells responded to flagellin, no response was detected upon stimulation with profilin. Furthermore, TgPr failed to elicit IL-6 secretion in human peripheral blood mononuclear cells and CD14+ monocytes. In contrast, exposure of RAW cells, known to express TLR11, to TgPr slightly increased the IL-6 response. Our data cast doubts on the possibility that profilin is a specific ligand for human TLR5 and bovine TLR5. This leaves the immunogenic properties of this potential target antigen (Ag) uncharacterised outside of the murine system.
Two pregnancies after simultaneous pancreas–kidney transplantation: A case report
Authors: Mohammadi Fadak , McDonald Stephen , Clark Erin , Jesudason Shilpanjali
Published: September 2018

Simultaneous kidney–pancreas transplantation can successfully restore fertility in women with type 1 diabetes mellitus and kidney failure. There have been few cases of pregnancy after simultaneous kidney–pancreas transplantation, and a second pregnancy is rare. We report a case of two live births in rapid succession in a simultaneous kidney–pancreas transplantation recipient, complicated by pre-eclampsia but with excellent fetal and graft outcomes. The first pregnancy was achieved with IVF, while the second was achieved naturally. Simultaneous kidney–pancreas transplantation with stable pre-pregnancy graft function enabled this patient to achieve successful pregnancy. However, both pregnancies were complicated by transient renal graft dysfunction and pre-eclampsia precipitating pre-term birth.
In vitro comparison of wear characteristics of PyroCarbon and metal on bone: Shoulder hemiarthroplasty
Authors: Klawitter Jerome J , Patton Jason , More Robert , Peter Noel , Podnos Evgeny , Ross Mark
Published: September 2018

Background

There are concerns regarding glenoid erosion with metal shoulder hemiarthroplasty. PyroCarbon may offer an alternative because of favorable wear characteristics and preservation of the glenoid. The purpose of this study was to assess in vitro bone wear characteristics of PyroCarbon relative to cobalt chromium alloy hemiarthroplasty in a shoulder wear simulator.

Methods

Wear of PyroCarbon and cobalt chromium prostheses articulating with bone were characterized by means of bone wear penetration rate, changes to surface roughness, and wear particle analysis.

Results

PyroCarbon prostheses produced significantly less damage to bone and were less damaged by the bone than cobalt chromium prostheses. Cobalt chromium testing was halted at approximately 320,000 cycles because the bone was consumed. Wear testing of PyroCarbon specimens continued through five million cycles. Linearized bone penetration rate, bone volume loss rate, and surface roughness for cobalt chromium test specimens were 30 times greater than for PyroCarbon.

Conclusions

Results demonstrate significantly less damage to bone in simulated shoulder function testing for PyroCarbon hemiarthroplasty implants relative to conventional cobalt chromium implants. Our study supports use of PyroCarbon in humeral head hemiarthroplasty as a viable alternative to conventional metal hemiarthroplasty. Further investigation of PyroCarbon performance in clinical settings is warranted.
Assessment of Memorandum Writing in a Quantitative Business Context

Published: September 2018

This article examines a manageable approach that provides students with significant opportunities to write and improve their writing over time in an introductory quantitative business course. The study examines six elements of written communication skills, as evidenced by assessment data from memorandum assignments administered following pedagogical interventions throughout the semester in an operations management course. Results demonstrate that student performance of audience identification, action-oriented request, and punctuation improved. Interestingly, student performance of grammar slightly decreased. A follow-up analysis indicates that some writing mistakes were related to a lack of proofreading. This article also presents original memorandum assignments and suggestions for improvement.
Parcels, points, and proximity: Can exhaustive sources of big data improve measurement in cities?
Authors: Kane Kevin , Kim Young-An
Published: September 2018

While there has been no shortage of discussion of urban big data, smart cities, and cities as complex systems, there has been less discussion of the implications of big data as a source of individual data for planning and social science research. This study takes advantage of increasingly available land parcel and business establishment data to analyze how the measurement of proximity to urban services or amenities performed in many fields can be impacted by using these data—which can be considered “individual” when compared to aggregated origins or destinations. We use business establishment data across five distinctive US cities: Long Beach, Irvine, and Moreno Valley in California; Milwaukee, Wisconsin; and the New York borough of Staten Island. In these case studies, we show how aggregation error, a previously recognized concern in using census-type data, can be minimized through careful choice of distance measures. Informed by these regions, we provide recommendations for researchers evaluating the potential risks of a measurement strategy that differs from the “gold standard” of network distance from individually measured, point-based origins and destinations. We find limited support for previous hypotheses regarding measurement error based on the abundance or clustering of urban services or amenities, though further research is merited. Importantly, these new data sources reveal vast differences across cities, underscoring how accurate proximity measurement necessitates a critical understanding of the nuances of the urban landscape under investigation as measures appear heavily influenced by a city’s street layouts and historical development trajectories.

Wildlife is persisting in urban areas of Australia even though white settler colonialism has resulted in the large-scale destruction of forested landscapes. While many bird species are in decline, the Sulphur-crested Cockatoo has found emergent opportunities for flourishing within the built environment. Cockatoos are actively generating relationally constituted spaces, drawing humans into urban ecosystems that are ‘more-than-human’ places, abundant and lively multispecies communities. Beginning in 2011, yellow tags attached to the wings of cockatoos, along with a smart-phone app and a Facebook page, have enabled scientists to collect data about these birds’ movements. These tracking technologies were quickly co-opted by an emergent public for their own purposes, including speculating about the personalities, relationships, intentions, and desires of individual birds. Interspecies friendships formed between humans and birds – involving shared understandings, emotional resonances, ongoing social exchanges, and utilitarian arrangements. We used the wingtags and the associated digital infrastructure as an opportunity to experiment with new modes of collaborative research and teaching in multispecies ethnography. Bringing together a flock of academics and students, we explored emergent social spaces involving people and birds. While many participants who fed the birds worried that they would become tame, we found multispecies flocks were fleeting associations where wild and unruly behaviours redoubled as people offered up food. We found that wildness emerged in intimate encounters with other species, encounters that were often characterised by shared but unequal vulnerabilities. Some cockatoos have been killed, after conflicts over property damage led authorities to identify them as nuisance animals. Against the backdrop of asymmetrical risks, we studied flocks of birds as models of, and models for, fleeting forms of association and collaboration. In these spaces, feelings of interspecies attraction quickly alternated with agitated and uncomfortable experiences. Amid animated encounters, people explored the ethics of inclusivity and conviviality.
How I treat breast implant–associated anaplastic large cell lymphoma
Authors: Mehta-Shah Neha , Clemens Mark W. , Horwitz Steven M.
Published: September 2018

Breast implant–associated anaplastic large cell lymphoma (BIA-ALCL) is a recently described form of T-cell non-Hodgkin lymphoma now formally recognized by the World Health Organization classification of lymphoid neoplasms. The disease most often presents with a delayed seroma around the breast implant, almost exclusively with a textured surface, and manifests with breast pain, swelling or asymmetry, capsular contracture, but can also present with a breast mass, and lymph node involvement. The prognosis of BIA-ALCL is favorable compared with many other subtypes of systemic T-cell lymphoma; however, unlike other non-Hodgkin lymphomas, complete surgical excision for localized disease is an important part of the management of these patients. In this paper, we share our recommendations for a multidisciplinary team approach to the diagnosis, workup, and treatment of BIA-ALCL in line with consensus guidelines by the National Comprehensive Cancer Network.
First-Line Therapies for Metastatic Lung Adenocarcinoma Without a Driver Mutation
Authors: Bodor J. Nicholas , Kasireddy Vineela , Borghaei Hossein
Published: September 2018

Lung cancer is the leading cause of cancer-related death worldwide. The majority of these cancers are non–small-cell lung cancer, of which adenocarcinoma is the most common histologic subtype. Most patients are diagnosed at advanced stages when systemic treatment is needed. Whereas prognosis has improved for patients with targetable driver mutations, the majority of patients do not possess tumors with such molecular mutations. Platinum-based chemotherapy has traditionally been the mainstay of treatment, although in recent years immunotherapy has emerged as a treatment option and can result in robust and durable treatment responses in a subset of patients. Recent clinical trials on novel immunotherapy combinations and immunochemotherapy combinations may broaden the number of patients that may benefit from checkpoint inhibitors and elicit responses in those who otherwise may not have experienced a response to monotherapy with an immunotherapy drug. This review will outline the currently available therapies for the first-line treatment of metastatic adenocarcinoma that do not possess a driver mutation and provide a recommended approach and algorithm by which to select the best first-line therapy.
Radiofrequency Ablation of the Stellate Ganglion for Management of Acute Digital Ischemia: A Case Report
Authors: Sekhri Nitin K. , Parikh Shalvi , Foo R. Marcus
Published: September 2018

The authors present a report of a pulsed radiofrequency ablation of the stellate ganglion performed on a patient with microemboli to the hand from a thrombosed abandoned arteriovenous fistula. The patient was initially managed using vasodilators and anticoagulation. However, the patient’s skin mottling, pain, and decreased strength persisted. Ablation of the stellate ganglia increased perfusion to his hand and likely prevented amputation that has lasted for approximately 1 year. While radiofrequency ablation is more commonly used for pain syndromes, this is an example of its use in the treatment and potential treatment of acute ischemia.
Hemodynamic Instability and Lipid Emulsion Resuscitation After Subcutaneous Injection of a Liposomal Bupivacaine Admixture: A Case Report
Authors: Tran Bryant W. , Liebman Spencer T. , Reichman Trevor W. , Scott Michael J.
Published: September 2018

This case report describes a patient whose blood pressure decreased from a systolic pressure of 130–140 to 70–80 mm Hg after receiving extended-release liposomal bupivacaine in combination with plain bupivacaine. An 83-year-old woman with hepatocellular carcinoma presented for right hepatectomy and cholecystectomy. No hemodynamic instability was noted during the procedure. When an admixture of liposomal bupivacaine and bupivacaine hydrochloride was infiltrated into the surgical incision site during skin closure, the patient then became profoundly hypotensive. Her blood pressure was supported with phenylephrine boluses and continuous phenylephrine infusion. Lipid emulsion therapy was given to treat suspected local anesthetic toxicity. In response, the patient’s blood pressure recovered and the vasopressor requirement was significantly reduced.
Coronary artery disease, genetic risk and the metabolome in young individuals
Authors: Battram Thomas , Hoskins Luke , Hughes David A. , Kettunen Johannes , Ring Susan M. , Smith George Davey , Timpson Nicholas John
Published: September 2018

Background:Genome-wide association studies have identified genetic variants associated with coronary artery disease (CAD) in adults – the leading cause of death worldwide. It often occurs later in life, but variants may impact CAD-relevant phenotypes early and throughout the life-course. Cohorts with longitudinal and genetic data on thousands of individuals are letting us explore the antecedents of this adult disease.

Methods:149 metabolites, with a focus on the lipidome, measured using nuclear magnetic resonance (1H-NMR) spectroscopy, and genotype data were available from 5,905 individuals at ages 7, 15, and 17 years from the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Linear regression was used to assess the association between the metabolites and an adult-derived genetic risk score (GRS) of CAD comprising 146 variants. Individual variant-metabolite associations were also examined.

Results:The CAD-GRS associated with 118 of 149 metabolites (false discovery rate [FDR] < 0.05), the strongest associations being with low-density lipoprotein (LDL) and atherogenic non-LDL subgroups. Nine of 146 variants in the GRS associated with one or more metabolites (FDR < 0.05). Seven of these are within lipid loci: rs11591147PCSK9,rs12149545HERPUD1-CETP,rs17091891LPL,rs515135APOB,rs602633CELSR2-PSRC1,rs651821APOA5,rs7412APOE-APOC1.All associated with metabolites in the LDL or atherogenic non-LDL subgroups or both including aggregate cholesterol measures. The other two variants identified were rs112635299SERPINA1and rs2519093ABO.

Conclusions:Genetic variants that influence CAD risk in adults are associated with large perturbations in metabolite levels in individuals as young as seven. The variants identified are mostly within lipid-related loci and the metabolites they associated with are primarily linked to lipoproteins. This knowledge could allow for preventative measures, such as increased monitoring of at-risk individuals and perhaps treatment earlier in life, to be taken years before any symptoms of the disease arise.

Lyeanda Berry and Polly Smith explore the obstacles and opportunities of the training and education requirements of practice nurses and their teams

Practice nursing has evolved radically since its inception to be a multifaceted role that is key to the functioning of an effective general practice. During a review of the practice nurse workforce in a selection of general practices in York, the fundamentals of training and education of the workforce were highlighted as requiring attention. The nursing teams often struggle to achieve continued professional development and national recommendations for training and education are often not taken on board or supported. This article explores the obstacles and opportunities of the training and education requirements of practice nurses and their teams.

Demanding knowledge is a must for every muslim and muslimah. There are many ways to gain knowledge, especially at this time. The Minangkabau people make wander as a culture and a very supportive method in the process of studying. The process resulted a tradition that related or based on the Prophet's hadith. This phenomenon has occurred since Islam entered Minangkabau, so it’s called by living hadith. Go out from native city or wander to get some knowledge outside, is a proof that Islam has entered Minangkabau. And it is recorded in history that Shaykh Ahmad Khatib al-Minangkabawi has done wander in studying to Masjid al-Haram and became khadim there at the end of the 19th century.

Öz-Yeterlik İnanç Ölçeği” uygulanmıştır. 

“Müziksel Öz-Yeterlik İnanç Ölçeği”nin geçerliğini
sınamak için kapsam geçerliği, ölçüt geçerliği ve yapı geçerliği çalışmaları
yapılmıştır. Ölçeğin güvenirliğini sınamak için ise iç tutarlılık ve madde
analizlerinden yararlanılmıştır. Yapılan tüm çalışmalar sonucunda geliştirilmiş
olan ölçeğin geçerli ve güvenilir olduğu görülmüştür. Bu ölçeğin öğretmen
adaylarına uygulanmasından elde edilen veriler frekans, yüzde, aritmetik
ortalama ve t testi gibi istatistiksel analiz yöntemleri kullanılarak analiz
edilmiştir. 

Araştırma sonucunda, öğretmen adaylarının müziksel
öz-yeterlik düzeylerinde değişkenlikler saptanmıştır. Buna göre öğretmen adaylarının
müzik etkinliklerine öğrencileri motive etme alanında öz-yeterlik düzeylerinin
yüksek olduğu bulgusuna ulaşılmıştır. Müzik etkinliklerinde müzikal unsurlarla
birlikte zamanı etkin kullanma yönünden ise öz-yeterlik düzeylerinin düşük
olduğu saptanmıştır. Ayrıca cinsiyet, öğrenim türü, ders notu gibi
değişkenlerle ölçek puanları arasında anlamlı bir fark bulunmadığı sonucuna da
ulaşılmıştır.

Published: September 2018

Çokkültürlülük,
ırk, etnik yapı, dil, cinsel yönelim, cinsiyet, yaş, engelli olma, sosyal
sınıf, eğitim, dinsel yönelim ve diğer kültürel boyutların farkına varılmasını
içermektedir. Eğitim sürecinde önemli bir role sahip olan öğretmenlerin de
çokkültürlülük konusunda nitelikli bir donanımla yetişmiş olmaları son yıllarda
önemli bir gereksinim olarak görülmektedir. Bu çalışmanın amacı 1. 3. sınıfta öğrenim
görmekte olan öğretmen adaylarının çokkültürlülüğe ilişkin algılarını farklı
değişkenler açısından incelemektir. Çalışmada var
olan durumun ortaya konulması söz konusu olduğu için betimsel araştırmalarda
başvurulan survey (tarama) yöntemi kullanılmıştır. Araştırma 316 öğrenci ile
Dokuz Eylül Üniversitesi 1. ve 3. sınıf öğrencileri ile gerçekleştirilmiştir.
Araştırmaya Türkçe Eğitimi ana bilim dalından 149, sınıf eğitimi ana bilim
dalından 167 öğrenci katılmıştır. Verilerin elde edilmesinde Ayaz (2016) tarafından
geliştirilen “Çokkültürlülük Algı Öçeği” 
kullanılmıştır. Araştırmadan elde edilen sonuçlara göre öğretmen
adaylarının çokkültürlülüğe ilişkin algıları anne ve baba eğitim durumuna; bir
yılda okudukları kitap sayısına; cinsiyetlerine; öğrenim gördükleri bölüme;
sürekli yaşadıkları bölgeye; sınıf düzeylerine göre anlamlı bir farklılık
göstermemektedir. Elde edilen sonuçlar öğretmen adaylarının kültürel ve
bireysel farklılıklara ilişkin algılarının benzer olduğunu göstermektedir. Öğretmen adaylarının çokkültürlülüğe ilişkin olarak olumlu
bir tavır geliştirmeleri farklı öğrencilerin topluma kazandırılması açısından
önemlidir.

Published: September 2018

Erken çocukluk döneminde zor durumlarla baş
eden çocuklardaki ego sağlamlığının oluşmasında, duygusal düzenlemenin önemli
bir etken olduğu bulunmuştur (Bonanno ve Diminich 2013). Bu araştırmanın amacı
duygu düzenleme becerilerinin ego sağlamlık düzeyi ile ilişkisini Türkiye’deki
okul öncesi dönemi çocuklarında ortaya koymaktır. İlişkisel tarama modelinde
tasarlanan araştırmanın çalışma grubunu 2015-16 öğretim yılında İstanbul
ilindeki anaokullarına devam eden, 60-72 aylık 288 çocuk ve anneleri
oluşturmaktadır. Veri toplama araçları olarak "Kişisel Bilgi Formu",
"Çocuk Ego Sağlamlığı Ölçeği" ve "Duygu Düzenleme Ölçeği"
kullanılmıştır. Sonuçlar, okul
öncesi dönem çocuklarda duygu düzenleme becerilerinin ego sağlamlık düzeyine
göre farklılaştığını ortaya koymuştur. Yaş ve
cinsiyet değişkenlerinin ise çocukların ego sağlamlık ve duygu düzenleme
becerileri üzerinde etkisi olmadığı bulunmuştur. Ayrıca cinsiyet, yaş ve duygu
düzenleme becerisinin ego sağlamlık düzeyi üzerindeki birlikte etkisine
bakıldığında, bu üç değişkenin birlikte ego sağlamlık düzeyi üzerinde etkili
olmadığı bulunmuştur.

Muhasebe Meslek Mensupları Açısından Muhasebe Denetiminin Sosyal Sorumluluk Kavramının Uygulanmasındaki Etkisi: Burdur İli Örneği
Authors: Apalı Ali
Published: September 2018

Sosyal sorumluluk kavramı, kişilerin değil
toplumun çıkarlarını ve refahını öne çıkaran bir kavramdır. Toplum refahının
artması, yüksek kalitede kamu hizmetlerinin yerine getirilmesi ile mümkün
olmaktadır. Kamu hizmetlerinin yerine getirilmesi, işletmelerin kar öncelikli
taleplerinden ziyade toplum çıkarlarına hizmet eden taleplerini karşılayan
meslek mensupları ile mümkün olacaktır. Bu nedenle sosyal sorumluluk kavramı
muhasebe meslek mensuplarını doğrudan ilgilendiren bir kavramdır. Sosyal
sorumluluk kavramının uygulanabilirliği üzerinde muhasebe denetiminin
etkinliğinin tanımlayıcı değişkenlere göre araştırılması çalışmanın amacı
olarak belirlenmiştir. Bu amaç doğrultusunda hazırlanan yedi adet hipotez SPSS
20.0 versiyonlu paket program aracılığı ile t testi ve anova testlerine tabi
tutulmuştur. Analiz sonucunda muhasebe meslek mensupları açısından muhasebe
denetiminin sosyal sorumluluk kavramı üzerindeki etkisinde ortaya çıkan tutum
farklılığının cinsiyet, yaş grubu, öğrenim durumu, meslek ünvanı, mesleki
tecrübe ve mükellef sayıları değişkenlerinde anlamlı olmadığı, sadece faaliyet
merkezi (il merkezi-ilçeler) değişkeninde ortaya çıkan tutum farklılığının
anlamlı olduğu ortaya çıkmıştır. Dolayısıyla altı hipotez red ve bir hipotez
kabul edilmiştir.
Düşünce İnşasında Kavramsallaştırmanın Önemi: Paul Tillich’in Kullandığı Temel Kavramların Felsefî Analizi
Authors: ILGAROĞLU Muhammet Caner , TURAN Mustafa
Published: September 2018

Her düşünce, ait olduğu zihnin anlam
dünyasında inşa edilirken hem varlık/olgu hem zihin hem dil alanında
varolmaktadır. Bütün bu varoluşsallığı yaşayan düşünce, kavramsallaştırılmış
demektir. Batı dillerinde “conception” biçiminde kullanılan kavramsallaştırma
sözcüğü, Latincedeki kavram anlamına gelen “conceptio” kelimesinden türemiştir.
Kavramlar olmadan yeni bir düşüncenin inşa edilmesi imkânsızdır. Kavramlar,
düşünme eyleminin vazgeçilmez unsurlarıdır. Düşünme eylemi, onlar olmaksızın ne
harekete geçebilir ne de düşünmeye konu olan herhangi bir şeyi kavrayıp
anlayabilir. Kavramlar, onu üreten zihnin, medeniyetin ve dilin özgün niteliklerinin
taşıyan, onları diğerlerinden ayıran temel entelektüel unsurlardır. Kavram
üretemeyen zihinler, diller, medeniyetler düşünce sahibi de olamayacakları için
süreç içerisinde kaybolmaya mahkûm olurlar. Bu makale, Paul Tillich’in,
düşüncelerini üzerine inşa ettiği kavramları analiz etmek suretiyle
kavramsallaştırmanın düşünce inşası açısından önemini felsefî bir örnek
üzerinden ortaya koymayı hedeflemektedir.
Fixed-Mobile Substitution in MENA Countries: The Future of Fixed-Line Markets
Authors: Ezzat Riham Ahmed
Published: September 2018

The aim of this paper is to study the occurrence of Fixed-Mobile Substitution (FMS) in the Middle East North African (MENA) region. While there have been many studies on developed countries, empirical evidence for developing countries is somehow limited. In the last few years, mobile cellular subscriptions achieved a tremendous growth across the MENA region making it the second fastest growing region in the world in terms of mobile subscriptions in 2012, and the fastest growing region in terms of mobile traffic in 2014. Fixed subscriptions have also grown but at a slower rate than mobile subscriptions. Using unbalanced data on 17 MENA countries over the period 1990–2009, we explore the relationship between fixed and mobile telephone services by using dynamic panel data models. We find empirical evidence for asymmetric one-way substitution between fixed-lines and mobile phones and we estimate own- and cross-price elasticities for fixed and mobile telephone services in MENA region. The results are then used to derive policy implications in terms of market redefinition, taxation policies, extension of universal services and broadband markets.
A pécsi Fabrica

Published: September 2018

This article provides information on a copy of the 1543 edition of Andreas Vesalius’ De humani corporis fabrica, preserved at the Klimo Library of the University of Pécs. This copy helps us understand the complex reception of Andreas Vesalius’ groundbreaking anatomical work amongst Lutherans in the sixteenth century, and shows the importance of the University of Wittenberg, and Philipp Melanchthon, in shaping anatomical knowledge in Germanic lands. It also documents the tight connections between Wittenberg and the University of Padova, and reveals the continuing importance of Ancient learning for physicians working in the wake of the Vesalian revolution.

Pécs városa méltán büszkélkedhet azzal, hogy Baranya megye helyneveinek és nyelvjárásainak kutatásában országos jelentőségű eredmények születtek. Temesi Mihályon, Rónai Bélán, Madas Józsefen és Reuter Camillón kívül ebben kiemelten fontos szerep jutott Pesti János nyelvésznek, aki 80. életévét meghazudtoló fiatalos lendülettel és szorgalommal folyamatosan dolgozik, szaktanulmányokat és önálló köteteket publikál. 
A Janus Pannonius (majd Pécsi) Tudományegyetem (JPTE/PTE) egykori nyelvész hallgatójaként, valamint az universitas keretein belül működő Pécsi Egyetemtörténeti Gyűjtemény gondozójaként fontos kötelességemnek éreztem, hogy riportot készítsek a hiánypótló baranyai és pécsi helynévkutatások kiemelkedő és meghatározó szakemberével, Pesti Jánossal, akire a mai napig halk szavú, nagy tudású, lelkes tanárként emlékeznek tanítványai.
