Authors: BELLER DİKMEN Beyhan
Published: May 2021

İnsanların ve ürünlerin yer değiştirme ihtiyaçları sonucunda ortaya çıkan taşımacılık, lojistik faaliyetler arasında en yüksek paya sahip olan faaliyettir. İnsanların yaşamlarını devam ettirebilmelerinde ihtiyaç duydukları ürünlerin üretilebilmesi için gerekli olan hammaddelerin elde edilmesi, hammaddelerin üretim birimlerine sevk edilmesi, üretilen mamullerin pazarlara ve tüketicilere ulaştırılması vb. aşamaların hepsinde taşıma faaliyeti gerçekleştirilmektedir. Taşıma faaliyetinin gerçekleştirilmesi aşamasında karayolu, demiryolu, havayolu, denizyolu ve boru hattı taşıma türlerinden yararlanılmaktadır. Bu türlerin her birinin dikkate alınması ile oluşturulan işletmelerin finansal performanslarındaki değişimin analiz edilmesi işletme yöneticilerinin alacakları kararların daha doğru olması açısından büyük önem taşımaktadır. Bu kapsamda, 2009 – 2019 yılları arasında Türkiye’de denizyolu yük taşımacılığı hizmeti veren işletmelerin finansal performanslarının değerlendirilmesi amaçlanmıştır. Bu amaç doğrultusunda denizyolu yük taşımacılığı sektöründe faaliyet gösteren işletmelere ait veriler Türkiye Cumhuriyet Merkez Bankası sektör bilançolarından elde edilmiştir. Elde edilen verilerin analizleri oran analizi yöntemi aracılığı ile gerçekleştirilmiştir. Analiz sonuçlarına göre denizyolu yük taşımacılığı sektörünün kısa vadeli borçlarını genel olarak zorlanmadan ödeyebildiği, varlıklarının çoğunlukla uzun vadeli yabancı kaynaklar kullanılarak finanse edildiği belirlenmiştir. Sektörün 2011, 2013 ve 2016 yıllarında net satışlar üzerinden zarar ettiği, çalışma kapsamındaki diğer yıllarda ise kar ettiği tespit edilmiştir.
ANALISA PEMILIHAN BENTUK VORTEX GENERATOR UNTUK SAYAP PESAWAT LSU-05 MENGGUNAKAN METODE NUMERIK

Published: May 2021

In this paper, numerical investigation on the fuselage structure of LSU 05 NG was carried out. This fuselage is designed to carry the payload up to 30 kg. Statical numerical analysis using finite element method was done using Simulia Abaqus. The fuselage structure that has been design consists of frame, longeron, and skin that can also be semi-monocoque structure. This airframe use combination of balsa and GFRP type of composite as the material. There are three load case: take-off condition, cruise condition, and landing condition. Tsai-hill failure criteria is used to investigate the strength of the composite structure due to the load that applied. Maximum stress from this calculation is 48 Mpa at the ground condition (take-off and landing) while the cruise stress analysis is 16 Mpa. The maximum tsai-hill criterion is 0,83. With such simulation results it can be said that the fuselage structure is still safe when operated and can also be optimized for several components so that the weight of the aircraft can be reduced.
Roll Amplification of Solid Rocket Motor in LAPAN Sounding Rocket
Authors: Sudiana Oka
Published: May 2021

Sounding rockets have been used for scientific research and implemented in meteorological and upper atmosphere studies since the late 1950s. Sounding rockets are sub-orbital carriers that follow a parabolic trajectory from launch to landing. Supporting the roadmap of Satellite Launch Vehicle development, LAPAN had launch The Sounding Rocket Program. A sensitive amplification from the production of an unpredicted roll rate was detected during the boost of the sounding rocket, despite of the tail wings in cruciform configuration at last flight test. One of this phenomenon can be influenced by the flow field of the combustion chamber during boosting time. The basic idea of this research is to model the roll amplification effect as a swirling motion of portion of exhaust gas that participate to the rotation dynamics of the rocket rather than to exit immediately flow the combustion chamber. Available flight data where is obtained from last flight test presented. It is shown the presence of a significant roll amplification when solid rocket motor is used during burning time. The result has a good agreement to presence of a portion of exhaust gas influence an unpredicted roll amplification.

Riflessioni in tema di comparazione, diritto transnazionale e lex sportiva
Authors: Cavallaro Nicola
Published: May 2021

"Con questo articolo si intende svolgere una riflessione sul grado di autonomia della lex sportiva sovranazionale rispetto agli altri sistemi di norme, prendendo in considerazione tre fattispecie che hanno suscitato molto dibattito nella prassi: il divieto di promozione pubblicitaria dei prodotti di tabacco ed assimilati in occasione di manifestazioni sportive, il problema dei diritti audiovisivi in relazione ad eventi sportivi e la fattispecie della c.d. Third Party Ownership nel rapporto tra normativa FIFA e quella della Unione Europea in tema di concorrenza.
In alcuni casi, come nel conflitto tra UEFA e FIFA da un lato ed Unione Europea dall’altro, sulla gestione dei diritti televisivi in ambito sportivo, è intervenuta la giurisprudenza della Corte di Giustizia dell’Unione Europea a risolvere la questione. In altri casi, si vuole mettere in rilievo come il conflitto in realtà si ponga solo come potenziale, ovvero apparente qualora si adotti un approccio rispettoso degli ambiti propri dei diversi sistemi di norme."

Psicología para un mundo de desigualdades, dominación y machismo
Authors: Almeida Eduardo
Published: May 2021

Planteamiento

Nuestras inquietudes como psicólogos se centran en los procesos mentales y conductuales, que han sido los mismos en las culturas orientales, africanas y amerindias. Pero el origen de nuestra "ciencia", lo situamos en lo razonable. Hemos descuidado lo sabio y lo vital. Propongo la búsqueda de una psicología más universal y más relevante.

 

Desarrollo

Si quisiéramos una psicología para la inclusión de todos los humanos, tendríamos que enfocar nuestros afanes hacia otros horizontes, hacia un mundo de lo común y lo solidario. Mi experiencia en las comunidades puedo afirmar que los pueblos indígenas tienen una respuesta. Ahora o nunca es su tiempo.

 

Conclusión

Como psicólogos podemos organizar nuestras vidas con actos de resistencia y fraternidad contra los poderes que mantienen el capitalismo, la colonialidad y el patriarcado.

Pengaruh bahan baku batuan tampak pada ukuran alat. Pada kelompok gua di Gunung Watangan yang menggunakan batuan dengan tingkat silikaan rendah (batugamping) dituntut artisan yang andal. Hal tersebut disebabkan jenis batuan mudah rapuh dan pengendalian pangkasan sulit. Produk alat pada kelompok ini menunjukkan ukuran relatif besar (masif) disebabkan pangkasan dan penyerpihan yang diterapkan tidak optimal. Sedangkan produk alat pada kelompok gua di Sampung, Ponorogo merupakan alat mikrolit. Hal itu disebabkan bahan baku batuan memiliki tingkat silikaan relatif tinggi (rijang/chert dan kalsedon). Teknologi litik yang dikenalnya dapat dilakukan secara optimal sehingga menghasilkan produk alat berukuran kecil dengan pangkasan dan penyerpihan mikro baik primer maupun sekunder.

Published: May 2021

The Ratu Boko (or Ratu Baka) plateau, near Yogyakarta in southern central Java, is surrounded by an impressive array of Hindu and Buddhist shrines. Notable among these are the Prambanan temples to the north, and Candi Kalasan to the west, with the massive Borobudur stupa 40 kilometres to the northwest, and the lofty volcanoes Merapi and Merbabu towering over the northern landscape. The presence of dynamic mountains and Buddhist monuments makes the Ratu Boko heights an ideal spot for locating the lost palace of the Sailendra 'mountain lords', though they may well have resided on the plain or in a northern port. However that may be, Ratu Boko was the site of the famous Sailendra monastery, Abhayagirivihara, which had links with Sri Lanka.

This paper explores judgements about the replicability of social and behavioural sciences research, and what drives those judgements. Using a mixed methods approach, it draws on qualitative and quantitative data elicited using a structured iterative approach for eliciting judgements from groups, called the IDEA protocol (‘Investigate’, ‘Discuss’, ‘Estimate’ and ‘Aggregate’). Five groups of five people separately assessed the replicability of 25 ‘known-outcome’ claims. That is, social and behavioural science claims that have already been subject to at least one replication study. Specifically, participants assessed the probability that each of the 25 research claims will replicate (i.e. a replication study would find a statistically significant result in the same direction as the original study). In addition to their quantitative judgements, participants also outlined the reasoning behind their judgements. To start, we quantitatively analysed some possible correlates of predictive accuracy, such as self-rated understanding and expertise in assessing each claim, and updating of judgements after feedback and discussion. Then we qualitatively analysed the reasoning data (i.e., the comments and justifications people provided for their judgements) to explore the cues and heuristics used, and features of group discussion that accompanied more and less accurate judgements.
The impact of face masks on emotion recognition performance and perception of threat
Authors: Grahlow Melina , Rupp Claudia , Dernt Birgit
Published: May 2021

Facial emotion recognition is crucial for social interaction. However, in times of a global pandemic, where wearing a face mask covering mouth and nose is widely encouraged to prevent the spread of disease, successful emotion recognition may be challenging. In Study 1, we investigated whether emotion recognition, assessed by a validated emotion recognition task, is impaired for faces wearing a mask compared to uncovered faces, in a sample of 790 participants between 18 and 89 years. Additionally, perception of threat for faces with and without mask was assessed. We found impaired emotion recognition for faces wearing a mask compared to faces without mask, especially for those depicting anger, sadness and disgust. Further, we observed that perception of threat was altered for faces wearing a mask. In Study 2, we compared emotion recognition performance for faces with and without face mask to faces that are occluded by something other than a mask, i.e. a bubble as well as only showing the upper part of the faces. We found that, for most emotions and especially for disgust, there seems to be an effect that can be ascribed to the face mask specifically, both for emotion recognition performance and perception of threat. Methodological constraints as well as the importance of wearing a mask despite temporarily compromised social interaction are discussed.

We know little about the psychological experiences of children and young people who have participated in virtual group music-making during the Coronavirus disease (COVID-19) pandemic. Adopting a mixed-methods design, we worked across three music education hubs in the UK, with a total 13 virtual music groups. These included a range of mainstream ensembles, inclusive ensembles targeting young people with special educational needs and/or disabilities, and inclusive music production spaces, targeting young people from lower socio-economic backgrounds. Reported progress in intra- and inter-personal psychological outcomes was investigated using quantitative and qualitative staff session reports, which were collected since before the pandemic (n1 for in-person sessions = 87, n2 for virtual sessions = 68), and surveys distributed to tutors, young people, and their parents during the first and second United Kingdom (UK) national lockdowns (n3 for qualitative responses = 240, n4 for quantitative responses = 96). Satisfaction of three basic psychological needs of self-determination theory and their relation to joint music-making in virtual spaces was also observed in real time by the researchers performing quantitative checklist observations on 16 separate occasions. Findings indicated that virtual music groups represented a meaningful psychological resource for the participating children and young people, especially considering the lack of opportunities offered by their schools and other extra-curricular activities. Through their participation with virtual group music-making activities, young people used music as a tool for self-expression and emotion management, restored lost musical identities and confidence, and preserved treasured social connections. Virtual alternatives to group music-making appear to indirectly nurture the sense of belongingness, mediated by supportive staff behaviours, but their direct connection, which has been widely reported for in-person group music-making experiences, has not been observed in virtual music groups.

Online testing holds great promise for infant scientists. It could increase participant diversity, improve reproducibility and collaborative possibilities, and reduce costs for researchers and participants. However, despite the rise of platforms and participant databases, little work has been done to overcome the challenges of making this approach available to researchers across the world. In this paper, we elaborate on the benefits of online infant testing from a global perspective and identify challenges for the international community that have been outside of the scope of previous literature. Furthermore, we introduce ManyBabies-AtHome, an international, multi-lab collaboration that is actively working to facilitate practical and technical aspects of online testing as well as address ethical concerns regarding data storage and protection, and cross-cultural variation. The ultimate goal of this collaboration is to improve the method of testing infants online and make it globally available.

Prediction errors (PEs) are a keystone for computational neuroscience. Their association with midbrain neural firing has been confirmed across species and has inspired the construction of artificial intelligence that can outperform humans. However, there is still much to learn. Here, we leverage the wealth of human PE data acquired in the functional neuroimaging setting in service of a deeper understanding, using meta-analysis. Across 263 PE studies that have focused on reward, punishment, action, cognition, and perception, we found consistent region-PE associations that were posited theoretically or evinced in preclinical studies, but not yet established in humans, including midbrain PE signals during perceptual and Pavlovian tasks. Further, we found evidence for PEs over successor representations in orbitofrontal cortex, and for default mode network PE signals. By combining functional imaging meta-analysis with theory and basic research, we provide new insights into learning in machines, humans, and other animals.
Psychometrics of art: Validation of RizbA, a quantitative rating instrument for pictorial expression
Authors: Schoch Kerstin , Ostermann Thomas
Published: May 2021

Although art has been subject to psychological research for some time, the artwork itself received little attention in quantitative research. The rating instrument for two-dimensional pictorial works (RizbA) fills this gap by providing a tool for formal picture analysis. This study validates the questionnaire on 294 images created by 147 non-artists. In an online test-retest study the material was rated by 880 (T1) and 475 (T2) experts using RizbA. Statistical quality criteria, Principal component analysis and indices of factor similarity were computed. The overall test's capacity of differentiation yields a partial eta-squared of .28 (T1) and .33 (T2). Test-retest reliability is .93. PCA reveals an eight-factors solution. Tucker's coefficients of congruence range between |0.82| and |1.00|. Intraclass correlation coefficients are .81 (T1) and .84 (T2). Results indicate generalizability to amateurs' works. As the first reliable tool for picture analysis, RizbA allows a more detailed examination of art and its correlates.

Introduction: Safety leadership is the process of interaction between leaders and followers, through which leaders exert their influence on followers to achieve organizational safety goals under the circumstances of organizational and individual factors.

Objective: This study was aimed to assess leadership style and safety in oil and gas servicing firms in Portharcourt, Nigeria.

Methods: A cross-sectional study was conducted  among the junior-staff of the oil servicing firms. The Taro Yamane equation was used to generate appropriate sample size of 389 respondents from 16240 workers. Data analyses was done using analysis of variance (ANOVA).

Results: It was established that 230 (59%) respondents agreed that, leaders checked staff work on a regular basis to assess their progress and learning. Many respondents  (62%) averred that leaders didn’t gave any incentives for extra work. Also, 338 (87%)  respondents adduced that changes in policies were discussed with workers before they were carried out but, the input of the workers were not required, neither staff were expected to be innovative as opined by 76% respondents and leadership emphasis on the importance of quality was sustained. Albeit, workers weren’t allowed to contribute to control standards based on perception of problems.  The characteristics of leadership displayed in the companies imply the transactional type. This was because the rapport between workers and leaders wasn’t cordial.

Conclusion: The study therefore strongly recommends a review of the leadership style adopted for oil and gas workers in the area, while improving on the worker/leader relationships.
Formation and rupture of gas film of antibubble

The formation and rupture of gas film in the process of formation, rupture and coalescence of antibubbles were investigated by high-speed photography. It was found that a gas film will appear and wrap a droplet when the droplet hit a layer of liquid film or foam before impacting the gas-liquid interface. The gas film may survive the impact on the gas-liquid interface and act as the gas film of an antibubble. A multilayer droplet will be formed when the droplet hits through several layer of liquid films, and a multilayer antibubble will be formed when the multilayer droplet impact a gas-liquid interface or a single layer of foam on the liquid surface. The way to generate antibubbles by liquid films will undergo the formation and rupture of gas films. The coalescence of two antibubbles, which shows a similar merging process of soap bubbles, also undergo the rupture and formation of gas films. The rupture of gas film of antibubble caused by aging and impact is also discussed.
Blistering skin reaction with Mastisol in a patient with spina bifida: illustrative case
Authors: Bowman Robin M. , Thirunavu Vineeth , Lam Sandi
Published: May 2021

BACKGROUND

Patients with spina bifida have repeated interactions with the healthcare system and often require multiple surgeries throughout their lifetime. Latex precautions are often indicated owing to the high risk of anaphylactic reactions. The choice of dressing for these patients represents an opportunity for learning and standardization if appropriate. The authors discuss the various cases of skin reactions to Mastisol in the literature in comparison with their case and explore the possible mechanisms underlying this skin reaction given the high prevalence of latex allergy in patients with spina bifida.

OBSERVATIONS

The authors present the case of a 17-year-old girl with a history of spina bifida and shunted hydrocephalus who underwent a shunt externalization operation and subsequently developed an allergic contact dermatitis reaction to Mastisol liquid adhesive. Topical steroid cream was then administered, and signs and symptoms resolved over the next 3 days.

LESSONS

The choice of dressing should be considered carefully in patients with spina bifida given their repeated exposures and possible sensitivities. The authors aim to increase the awareness of the possibility of Mastisol-induced skin reactions in patients with spina bifida and set a foundation for future studies to investigate the relationship between latex allergy and sensitization to Mastisol.

Published: May 2021

BACKGROUND

Diffuse midline glioma H3 K27M-mutant is a distinct subtype of glial tumors newly introduced in the revised fourth edition of the World Health Organization Classification of Tumours of the Central Nervous System. They are aggressive pediatric tumors with a poor prognosis but have also been reported in adults.

OBSERVATIONS

The authors present the case of a man in his 60s who presented with rotatory vertigo, taste disorder, and right facial paralysis. Magnetic resonance imaging showed a tumor expanding from the cerebellum to the pons, which was histologically identified as glioblastoma, grade IV, IDH wild type. After tumor resection, the patient received chemoradiotherapy but showed only a partial response. His condition gradually worsened, and he died of progressive disease 12 months postoperation, after which an autopsy was performed. Tumor cells with a high nuclear-to-cytoplasm ratio were immunohistochemically analyzed and found to test positive for H3 K27M and negative for H3 K27me3. Furthermore, mutational analysis revealed HIST1H3B K27M mutation, and the tumor was finally identified as a high-grade glioma H3 K27M-mutant. The tumor invaded widely along the cerebral ventricle and disseminated to the spinal cord.

LESSONS

When a glioblastoma shows localization or dissemination patterns different from those of typical glioblastoma, an H3 K27M-mutant glioma should be suspected.
