Data-Driven Decisions for Problems with an Unspecified Objective Function
Authors: Sun Zhen , Dawande Milind , Janakiraman Ganesh , Mookerjee Vijay 
Published: January 2019

This study develops a data-driven approach to solve constrained optimization problems in which the decision maker does not have an analytic form for the objective function but knows what decision variables affect the function. The approach makes direct use of the available data, rather than first using the data to estimate the objective function and then solving the problem as a traditional optimization problem. The difficulty in first estimating the unknown objective function is that the decision maker needs to have sufficient knowledge of its properties that are necessary to guide the estimation process. Thus, our approach is appropriate for situations where such structural knowledge is absent, either because the domain is very complex or because the knowledge is deliberately hidden by a partner firm that has a vested interest in the outcome of the decision. Our approach comes with a worst-case performance guarantee that improves with the characteristics (size, pervasiveness) of the available data. We illustrate our technique on a traffic-stream mixing problem encountered by a supply side Internet advertising network that wishes to optimize the click revenue earned from ads. A head-to-head comparison (with the existing method used) on real data shows a significant increase (≥10%, on average) in the revenue. We also demonstrate the value of our approach under more general conditions. The online supplement is available at https://doi.org/10.1287/ijoc.2018.0818 .

Published: January 2019

Aims The aims of this study were to compare the use of resources, costs, and quality of life outcomes associated with subacromial decompression, arthroscopy only (placebo surgery), and no treatment for subacromial pain in the United Kingdom National Health Service (NHS), and to estimate their cost-effectiveness. Patients and Methods The use of resources, costs, and quality-adjusted life-years (QALYs) were assessed in the trial at six months and one year. Results were extrapolated to two years after randomization. Differences between treatment arms, based on the intention-to-treat principle, were adjusted for covariates and missing data were handled using multiple imputation. Incremental cost-effectiveness ratios were calculated, with uncertainty around the values estimated using bootstrapping. Results Cumulative mean QALYs/mean costs of health care service use and surgery per patient from baseline to 12 months were estimated as 0.640 (standard error (se) 0.024)/£3147 (se 166) in the decompression arm, 0.656 (se 0.020)/£2830 (se 183) in the arthroscopy only arm and 0.522 (se 0.029)/£1451 (se 151) in the no treatment arm. Statistically significant differences in cumulative QALYs and costs were found at six and 12 months for the decompression versus no treatment comparison only. The probabilities of decompression being cost-effective compared with no treatment at a willingness-to-pay threshold of £20 000 per QALY were close to 0% at six months and approximately 50% at one year, with this probability potentially increasing for the extrapolation to two years. Discussion The evidence for cost-effectiveness at 12 months was inconclusive. Decompression could be cost-effective in the longer-term, but results of this analysis are sensitive to the assumptions made about how costs and QALYs are extrapolated beyond the follow-up of the trial.

Published: January 2019

Aims The aim of this study was to investigate the incidence, risk factors, and outcome of venous thromboembolism (VTE) following anterior cruciate ligament (ACL) reconstruction in a nationwide cohort. Patients and Methods All ACL reconstructions, primary and revision, that were recorded in the Swedish Knee Ligament Register (SKLR) between 2006 and 2013 were linked with data from the Swedish National Board of Health and Welfare. The incidence of VTE was determined by entries between the day of surgery until 90 days postoperatively based on diagnosis codes and the prescription of anticoagulants. Risk factors, outcome, and the use of thromboprophylaxis were analyzed. Descriptive statistics with multivariate analysis were used to describe the findings. Results The cohort consisted of 26 014 primary and revision ACL reconstructions. There were 89 deep venous thromboses (DVTs) and 12 pulmonary emboli (PEs) with a total of 95 VTEs (0.4 %). Six patients with a PE had a simultaneous DVT. The only independent risk factor for VTE was age greater than or equal to 40 years (odds ratio 2.31, 95% confidence interval 1.45 to 3.70; p < 0.001). Thromboprophylaxis was prescribed to 9461 patients (36%) and was equally distributed between those with and those without a VTE (37.9% vs 36.4%). All patient-reported outcome measures (PROMs) one and two years postoperatively were significantly lower in those with VTE. Conclusion The incidence of VTE following ACL reconstruction is 0.4%, and the only significant risk factor is age. Patients with VTE had worse postoperative clinical outcome than patients without VTE. We recommend against the routine use of thromboprophylaxis, but it should be considered in older patients.
Practice variation in total hip arthroplasty versus hemiarthroplasty for treatment of fractured neck of femur in Australia
Authors: Harris I. A. , Cuthbert A. , de Steiger R. , Lewis P. , Graves S. E. 
Published: January 2019

Aims Displaced femoral neck fractures (FNF) may be treated with partial (hemiarthroplasty, HA) or total hip arthroplasty (THA), with recent recommendations advising that THA be used in community-ambulant patients. This study aims to determine the association between the proportion of FNF treated with THA and year of surgery, day of the week, surgeon practice, and private versus public hospitals, adjusting for known confounders. Patients and Methods Data from 67 620 patients in the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) from 1999 to 2016 inclusive were used to generate unadjusted and adjusted analyses of the associations between patient, time, surgeon and institution factors, and the proportion of FNF treated with THA. Results Overall, THA was used in 23.7% of patients. THA was more frequently used over time, in younger patients, in healthier patients, in cases performed on weekdays (adjusted odds ratio (OR) 1.27; 95% confidence interval (CI) 1.14 to 1.41), in private hospitals (adjusted OR 4.34; 95% CI 3.94 to 4.79) and by surgeons whose hip arthroplasty practice has a relatively higher proportion of elective patients (adjusted OR 1.65; 95% CI 1.49 to 1.83). Conclusion Practice variation exists in the proportion of FNF patients treated with THA due to variables other than patient factors. This may reflect variation in resources available and surgeon preference, and uncertainty regarding the relative indication.

Published: January 2019

Aims The glenohumeral joint is the most frequently dislocated articulation, but possibly due to the lower prevalence of posterior shoulder dislocations, approximately 50% to 79% of posterior glenohumeral dislocations are missed at initial presentation. The aim of this study was to systematically evaluate the most recent evidence involving the aetiology of posterior glenohumeral dislocations, as well as the diagnosis and treatment. Materials and Methods A systematic search was conducted using PubMed (MEDLINE), Web of Science, Embase, and Cochrane (January 1997 to September 2017), with references from articles also evaluated. Studies reporting patients who experienced an acute posterior glenohumeral joint subluxation and/or dislocation, as well as the aetiology of posterior glenohumeral dislocations, were included. Results A total of 54 studies met the inclusion criteria. In total, 182 patients were included in this analysis; study sizes ranged from one to 66 patients, with a mean age of 44.2 years (sd 13.7). There was a higher proportion of male patients. In all, 216 shoulders were included with 148 unilateral injuries and 34 bilateral. Seizures were implicated in 38% of patients (n = 69), with falls, road traffic accidents, electric shock, and iatrogenic reasons also described. Time to diagnosis varied across studies from immediate up to a delay of 25 years. Multiple associated injuries are described. Conclusion This review provides an up-to-date insight into the aetiology of posterior shoulder dislocations. Our results showed that seizures were most commonly implicated. Overall, reduction was achieved via open means in the majority of shoulders. We also found that delayed diagnosis is common.

Abstract. Fighting anxiety often occurs in male and female athletes, as well as individual group sports and sports. The anxiety is a feeling of worry, anxiety, and uneasiness by considering the game as something dangerous. There are many factors that can cause an athlete to experience anxiety during a match that is dysfunctional thoughts and stress, academic problems, anxiety injuries, and poor team relationships. Other factors also exist from such individuals and the environment, such as negative thoughts on the outcome of the game, the pressure of the coach or supporters. Therefore, the fighting anxiety is very important to be known by every athlete or team that will compete, in order to be able to improve its best performance in the face of the game. This study used a quantitative approach measured using the scale of The Sport Interference Checklist (SIC) to measure athlete's anxiety. The subjects of the study were 110 people consisting of athletes of students in the Sports student Unit State Islamic University Maulana Malik Ibrahim Malang. With male gender of 64 people and 46 women, as well as individual sports from two sports that is badminton and table tennis totaling 31 people and sports groups from four sports that is soccer, volleyball, basketball, and sepak takraw amounted to 79 person. The analysis is descriptive analysis. The results showed that there was no difference between sex of male athlete with percentage 63,00% and woman equal to 66,89%, because anxiety at athlete evaluated from gender have no significance, and difference between type of individual sport with percentage 67, 12% and sports groups of 63.64%, if reviewed the anxiety of the athlete's sports type does not have significant. This means that athletes in the Sport students Unit equally have anxiety problems when playing.
Partial androgen insensitivity syndrome presenting as pubertal gynecomastia: clinical and hormonal findings and a novel mutation in the androgen receptor gene
Authors: Vaidyanathan Priya , Kaplowitz Paul 
Published: January 2019

Summary
Pubertal gynecomastia is common, can be seen in 65% of the adolescent boys and is considered physiological. It is thought to be due to transient imbalance between the ratio of testosterone and estradiol in the early stages of puberty. It resolves in 1–2 years and requires no treatment. However, more persistent and severe pubertal gynecomastia is less common and can be associated with pathological disorders. These can be due to diminished androgen production, increased estrogen production or androgen resistance. We report a case of persistent pubertal gynecomastia due to partial androgen insensitivity syndrome (PAIS), classical hormone findings and a novel mutation in the androgen receptor (AR) gene.

Learning points:

Laboratory testing of follicle-stimulating hormone (FSH), leutinizing hormone (LH) and testosterone for pubertal gynecomastia is most helpful in the setting of undervirization.

The hormonal finding of very high testosterone, elevated LH and estradiol and relatively normal FSH are classical findings of PAIS.

Gynecomastia due to PAIS will not resolve and surgery for breast reduction should be recommended.
Historia de una invención: realidad y ficción del supuesto autorretrato del Maestro Mateo en el Pórtico de la Gloria
Authors: Vigo Trasancos Alfredo 
Published: January 2019

La historiografía decimonónica difundió la opinión de que la figura arrodillada que se encuentra en la parte posterior del parteluz del Pórtico de la Gloria, en la catedral de Santiago, era un retrato o representación del Maestro Mateo, añadiendo además que, en la cartela que lleva en su mano izquierda, aparecía escrita la palabra “ARCHITECTUS”, hoy borrada. Sin duda se trata de una falsedad histórica que este artículo pretende demostrar, proponiendo asimismo una interpretación muy diferente del que, popularmente, se conoce también como “Santo dos Croques”.
Some remarks concerning Polish Japonisme movement from the Modernist Era
Authors: Pawłowska Aneta Joanna 
Published: January 2019

Polish Japonisme, i.e. Japanese art inspirations in the work of the Polish painters and printmakers of the early period of modernism (the late 19th and early 20th centuries).The article will present well-known Polish artists such as Olga Bozna?ska, Julian Fa?at, Wojciech Weiss, Leon Wyczó?kowski, Satnis?aw Wyspia?ski as well as Jan Stanis?awski and his talented students. Juxtaposing works done by Polish artists of the Young Poland period with selected examples of Japanese ukiyo-e woodblock prints and silk paintings (done by such masters as: Hokusai, Hiroshige and Utamaro) as well sculptures and artistic handicrafts, I will demonstrate this phenomenon seen from the 21century perspective. This new approach encourages the reader to make comparisons, to look – almost automatically – for similarities and differences between Polish and Japanese arts, and by revealing the clear and deep analogies between the two cultures, to engage in intercultural dialogue.Key words:Polish art, Japonisme, ukiyo-e prints.

Ahi Evran Vakfı ve Vakfiyelerinin Sosyo-Kültürel Açıdan Değerlendirilmesi / An Evaluation of Akhi Evran Waqf and Waqfıyyas from Socio-Cultural Perspective
Authors: ÇELİK Rifat İlhan 
Published: January 2019

Ahi kültürü ve geleneği hakkında somut bilgi veren en önemli kaynaklardan birisi de Ahi Evran vakfiyeleridir. Bu vakfiyeler dönemin sosyal, kültürel, dinî, ekonomik ve siyasî yapısı hakkında bilgiler ihtiva etmektedirler. Türkiye Selçukluları zamanında en çok İzzeddin Keykâvus ve Alâeddin Keykubat tarafından geniş olanaklara sahip vakıflar kurulmuştur. Bu vakıf kurmanın temelinde iyilikseverlik, yardımseverlik, cömertlik, dünyada hayır ederek ahiret için sevap kazanma düşüncesi vardır.Ahi Evran ve Ahilik çalışmaları açısından büyük bir öneme sahip olan Kırşehir Ahi Evran vakfiyesi Hicri 676/Miladi 1277 tarihinde Arapça olarak tanzim edilmiştir. Günümüze bu vakfiyenin suretleri ulaşmıştır. Bu çalışmada beş ayrı vakfiyenin suretlerinin mukayesesi yapılmak suretiyle bilgiler değerlendirilmiştir. Buna göre yirmi yedi ayrı yerleşim yeri ve mevki adları tespiti yapılmıştır.Vakfiyelere göre Ahi Evran güzel ahlak sahibi, zamanın kutbu, dünyanın en olgun şahsiyeti, Pîr-i Pîrân (Pirlerin Piri) Şeyh Nasurüddin Ahi Evran’dır. O dünyanın fani olduğunu anladıktan sonra malını mülkünü vakfedip, kendi tasarrufundan çıkarmış, sürekliğini sağlamış ve bu durumu hukuken tescil ettirmiştir.

Published: January 2019

Aksaray ili merkezine yaklaşık 35 km mesafede yer alan Yenipınar köyünde bulunan Hacı Gayb Türbesi, plan şeması, biçimi, tasarımı ve mimari öğeleri ile günümüze kadar ulaşabilmiş, II. grup yapı olarak tescil edilmiş bir vakıf kültür varlığıdır. Yapının vakfına, vakıf gelirlerine ve mevcut durumuna dair genel bilgiler veren çalışmalar mevcut olmakla birlikte, mimari anlamda yapıyı konu alan monografik bir araştırma bulunmamaktadır. Türbe, yerinde tespit ve literatür araştırması ile mimari ve tarihçesi bakımından incelenmiştir. Ayrıca, Hacı Gayb Türbesi kendinden gelen izler, yerinde yapılan tespitler, esere ait belge ve bilgi kaynaklarından elde edilen veriler doğrultusunda, günümüze kadar ulaşmış Aksaray ve çevre illerdeki türbeler, zaviye/tekke yapıları ile ilişkili olarak analiz edilmiştir. Bu bağlamda, dönem belirleme/karşılaştırma çalışmalarında kaynak oluşturması için yapı hakkında detaylı bilgi verilmeye çalışılmış, Aksaray dinî mimarisindeki yeri üzerinde durulmuştur. Bu araştırma ile müdahale görmüş olmasına rağmen Hacı Gayb Türbesi’nin mimari özellikleri, planı, tasarımı, yapım tekniği ve malzemesi ile büyük oranda özgünlüğünü koruduğu, Karamanoğulları dönemi dinî mimarisini yansıttığı sonucuna ulaşılmıştır.
Giresun Merkezde Yok Olmuş Bir Vakıf Eseri: Sultan Selim (Hüdavendigâr) Camisi / A Lost Waqf Monument in Central Giresun: Sultan Selim (Hüdavendigâr) Mosque
Authors: İLTAR Gazanfer , FATSA Mehmet 
Published: January 2019

Giresun şehrinin bilinen ilk Cuma camisi olarak değerlendirilen Sultan Selim Camisi, Liman sahası bitişiğindeki Taşbaşı Parkı’nın olduğu alanda 15. Yüzyılın sonlarına doğru inşa edilmiştir. Müslüman Türklerin ilk iskân alanı mahiyetindeki Sultan Selim Mahallesi bu cami çevresinde teşekkül etmiş ve adını günümüze kadar korumuştur. Ancak cami ve vakfına ait yapılardan hiçbiri günümüze ulaşmamıştır. Tahrir kayıtlarına göre aslında buraya cami yapma teşebbüsünün ilk olarak Şehzâde Abdullah’ın Trabzon valiliği sırasında başladığı anlaşılmaktadır. Kayıtlarda “Câmiʻ-i Hüdâvendigâr” diye de anılan bu yapıya dair bilgi veren kaynaklar daha çok 16. ve 19. yüzyıllara ait olup 17. ve 18. yüzyılda bir suskunluk söz konusudur. 19. yüzyılın ikinci yarısından itibaren çizim ve fotoğraf gibi görsellerle caminin tarihî serüveni, camiye ait yapılar ve vakıflarının tespiti, görevlileri, mimari özellikleri gibi hususlar bu yazının konusunu oluşturur.

Eğitim
sisteminden, yaratıcı ve analitik düşünebilen, çevresine geniş perspektiften
bakabilen, grup çalışmalarında diğer bireylerle iletişim kurabilen ve yenilik
yapabilen bireyler yetiştirmesi beklenir fakat geleneksel öğretim yöntem ve
tekniklerinin yaratıcı düşünme becerilerini körelttiği de bilinmektedir.
Bireylerin yaratıcı düşünme ve yaratıcı problem çözme becerilerinin
geliştirilmesinde işbirlikli öğrenme ortamlarının rolünün oldukça önemli olduğu
düşünülmektedir. Konu ile ilgili yapılan alanyazın taramasında Lavonen, Autio
