The object of research is the integration processes of strategic and project management at the enterprises of the transport complex. The rapid pace of development of science and technology requires modern effective management tools in any sector of the economy, in particular, in the transport sector. The effective development of the transport industry is of fundamental importance both for the development of regions and for the country as a whole. This is due to the fact that the availability of transport facilities is an essential condition for the development of productive forces, a means of meeting the demand for freight and passenger transportation, ensuring the socio-economic unity of the state. There is a need for a strategic approach to the management of transport enterprises, the development of a unified approach to the integration of strategic and project management at transport enterprises as their long-term goals and objectives. Therefore, it acquires particular importance as a means of implementing the action program, which clarifies the goals and means of implementing the chosen path of development.
The paper proposes the construction of a conceptual model for the integration of strategic and project management at the enterprises of the transport complex, based on the implementation of the following stages:
– analysis of the stages of strategic and project management of enterprises is carried out;
– process of integration of strategic and project management at the enterprises of the transport complex is being built;
– on the basis of the developed integration process, a conceptual model for the integration of strategic and project management at the enterprises of the transport complex is being built.
As a result of this research, a conceptual model for the integration of strategic and project management at transport enterprises was developed, which combined separate approaches to management. This result made it possible to obtain an effective tool for integrated strategic and project management of transport enterprises, which will be useful in the process of forming their development strategy.
Respondents’ perception of Risk Factors on Residential Property Development in Abuja, Nigeria
Authors: Ogunbayo Oyeronke T 
Published: May 2021

Significant risk factors such as social, technological, economic, environmental and political in the timing development, minimization of cost and expected return as they influence the successful delivery process of residential property development were investigated in this study towards enhancing real estate development decisions. This is expedient because it has been argued that the link between project success criterions determines a successful project delivery. Data were obtained from members of Real Estate Developers Association (REDAN) in Abuja through the use of a self-administered questionnaire. The respondents were asked to rate the influence of risk factors on residential property development parameters, and the data were computed using logistic regression analysis. The study revealed that real estate developers were more concerned with the influence of economic and technological risk than other sources of risk. Also, the statistical effects were computed through logistic regression analysis. It was explained by significant value (p<0.05) which depicts the likelihood of the risk factor which could either be positive or negative, as explained by beta (β). The findings revealed the effect of economic risk factors in timing development to be (β=1.833, p<0.05). Also, the effect of technological risk factors to influence development cost were found to be (β=--.187, p<0.05) while the effect of economic risk factors on return was found to be (β=1.026, p<0.05). The main contribution of the study to the body of knowledge is developing a risk factors assessment technique for practitioners and academia to assess the residential property development performance as related to timely completion, cost and returns to enhance the need to develop competence in managing and minimizing the effect of risk factors on the residential investment appraisal.

influência do ambiente geográfico no desempenho dos bancos islâmicos
Authors: El Khatib Ahmed Sameer 
Published: May 2021

O objetivo do presente artigo é examinar a influência do ambiente geográfico no desempenho de bancos islâmicos presentes em quatro regiões: África, Ásia, Europa e América do Norte. Para atingir esse objetivo, foram utilizados dados diários de 113 bancos islâmicos entre os anos de 2010 e 2019. Foram aplicadas diferentes abordagens metodológicas, como análise de componentes principais e regressão quantílica com efeitos fixos para dados em painel. Como resultados, descobrimos que a análise dos componentes principais mostra que o desempenho dos bancos islâmicos varia entre as regiões. A regressão do painel linear destaca que o ambiente geográfico afeta positiva e significativamente o sistema bancário islâmico, sugerindo a importância dos efeitos dessa externalidade. Finalmente, o efeito ambiental parece variar com os quantis, trazendo efeito positivo para o quantil mais baixo e efeito negativo para o quantil mais alto. Essa especificação quantílica aponta para a não linearidade na relação ambiente-desempenho do banco islâmico, refletindo uma disciplina variável no tempo imposta pelo conselho da Shariah ou de Lei Islâmica. Essa descoberta ajuda a explicar melhor a principal diferença entre os bancos islâmicos no oriente e os do ocidente e, também, permite que os investidores ajustem suas opções de portfólio ao considerar os produtos dos bancos islâmicos de acordo com as especificidades regionais.

Routine calcitonin measurement in patients with nodular thyroid disease is rather controversial. The aim of this study was to evaluate the contribution of serum calcitonin measurement in the diagnostic evaluation of thyroid nodules with insufficient, indeterminate, or suspicious cytology. Out of 1668 patients who underwent thyroidectomy with the diagnosis of nodular thyroid disease and were screened, 873 patients with insufficient, indeterminate, or suspicious fine needle aspiration biopsy results were included in the study. From the total number of patients in this study, 10 (1.1%) were diagnosed as medullary thyroid cancer (MTC) using histopathology. The calcitonin level was detected to be above the assay-specific cut-off in 23 (2.6%) patients ranging between 6.5 - 4450 pg/mL. While hypercalcitoninemia was detected in all 10 MTC patients, a false positive elevation of serum calcitonin was detected in 13 patients (1.5%). Of the MTC group, 7 patients had cytology results that were suspicious for malignancy (Bethesda V), one patient’s cytology showed atypia of undetermined significance (Bethesda III) and two patient’s cytology results were suspicious for follicular neoplasm (Bethesda IV). Among the cases with non-diagnostic cytology (Bethesda I), none of the patients were diagnosed with MTC. In conclusion, routine serum calcitonin measurement can be performed in selected cases rather than in all nodular thyroid patients. While it is reasonable to perform routine calcitonin measurement in patients with Bethesda IV and Bethesda V, this measurement was not useful in Bethesda I patients. In Bethesda III patients, patient-based decisions can be made according to their calcitonin measurement.

ASYMMETRICAL HEARING LOSS AND MEGA
CISTERNA MAGNA: A CASE STUDY
Authors: Alanazi Ahmad 
Published: May 2021

BackgroundThere is an unknown relationship between hearing loss, vestibular disorders, and mega cisterna magna. The purpose of this case
report is to describe, for the first time, hearing and vestibular examinations and rehabilitation for an older adult with mega cisterna magna.Case ReportThis study presents the case of a 54-year-old male who complained of being hard of hearing (bilaterally), tinnitus, and dizzy
spells. He had a history of working in noisy environments but no familial history of hearing loss. Several audiological and vestibular tests and
magnetic resonance imaging (MRI) were administered. The subject was counseled about hearing aids and fitted with a ‘bilateral contralateral routing of signal’ (BiCROS) amplification system to overcome his hearing difficulties.ConclusionsMega cisterna magna can be either silent and cause no symptoms, or produce symptoms such as hearing loss, tinnitus, and dizziness. Aging and noise exposure are major causes of hearing loss and tinnitus. Further research is needed to determine the audiological and
vestibular symptoms of a larger sample of patients with mega cisterna magna.
COMPARISON OF INVASIVE VERSUS
NON-INVASIVE ELECTRICAL EAR
STIMULATION IN TINNITUS SUPPRESSION:
LITERATURE REVIEW
Authors: Spencer Shikha , Sereda Magdalena , Schoisswohl Stefan , Olszewski Jurek , Mielczarek Marzena 
Published: May 2021

BackgroundThis paper is a review of the literature on electrical stimulation of the ear to treat tinnitus. This method of treatment
has been used since the 1970s and different techniques have been explored. The primary aim of this work was to review the literature on electrical stimulation of the ear to suppress tinnitus, with a specific focus on the methods and stimulation parameters used so far
and the efficacy of the different methods. A secondary aim was to formulate recommendations on electrical ear stimulation parameters that suppress tinnitus.Material and MethodsFour databases were searched: PubMed, Ovid Embase, Web of Science, and Science Direct. Database searches were
conducted during November 2018 using the search terms: tinnitus and electrical stimulation. Inclusion criteria: All research articles on invasive and non-invasive electrical stimulation of the ear for suppressing tinnitus were included. Other inclusion criteria were records in English
and involving adult human participants. Exclusion criteria: Studies on intracochlear stimulation using cochlear implants and studies where
stimulation extended beyond the ear (e.g. transcutaneous electrical nerve stimulation, TENS) were excluded.ResultsTwenty publications met the inclusion criteria and were analysed in this review. A comparison was made between invasive and
non-invasive electrical ear stimulation in terms of efficacy, type of current used, laterality of stimulation, intensity and frequency of the
current, duration of tinnitus suppression, and adverse effects. Due to the non-standardised methodology of the studies, there was only a low
level of evidence available in terms of the advantages of a particular technique or stimulation parameter. The difficulties in comparing the
effectiveness of the studies were related to many factors, and these are discussed. One factor is the variability in outcome measures, including
different definitions of treatment success and limited use of standardised or validated outcome measures.ConclusionsBased on the reviewed literature, it is concluded there is no clear advantage of one stimulation condition over the other in terms of method, stimulation parameter, or effectiveness. This leads us to conclusion that the present body of evidence is insufficient to formulate definite recommendations for electrical ear stimulation.

Published: May 2021

BackgroundThe purpose of the present study was to develop a nonsense suprathreshold speech audiometry test for native
speakers of Modern Greek. The specific aims were to construct phonemically balanced lists of nonsense monosyllables and to
perform a preliminary investigation of list equivalence.Material and MethodsNonsense monosyllables with possible CV, VC, and CVC phonemic combinations in Greek were chosen as stimuli. To examine list equivalency, the final recorded lists were administered monaurally in 5 dB increments to 40
adults (20 males and 20 females) whose hearing was within normal limits.ResultsA nonsense monosyllabic speech audiometry test for speakers of Modern Greek has been developed. The test material consists of two lists, each of which contains 50 open-set monosyllabic combinations. The lists satisfied the criteria of equal
phonemic balance, composition of Modern Greek speech, phonemic differentiation, and equal average difficulty. Statistical
analysis of the results revealed no statistical significant differences among the lists at the 0.05 level.ConclusionsThese findings suggest that the test is a useful tool for clinical purposes.

Published: May 2021

BackgroundConventionally, it is believed that high-frequency auditory information is important for speech understanding.
This is only partly true, as recent studies have demonstrated the importance of low-frequency information. This research was
taken up to develop, standardize, and validate auditory low-frequency word lists in Hindi, an Indian language.Material and MethodsThe first phase of the study involved collection of bisyllabic words followed by verification by a native
linguist. Words were then short-listed based on familiarity ratings given by 10 adult native speakers; those words were recorded and the best recorded words selected through subjective and objective analysis. Then, using Fast Fourier Transform and
k-means clustering, words with more energy below 1.5 kHz were isolated. Finally, equally difficult 10 word lists were generated by obtaining psychometric function curves. Finally, lists were administered on 40 adult normal hearing participResultsResults showed a similar trend of increase in speech identification scores with increase in SL across all lists except
list 4. During the final phase, developed lists were validated on 10 simulated low-frequency cochlear hearing loss participants.
Hearing loss was simulated using Matlab and National Institute for Occupational Safety and Health (NIOSH) software. Results of validation revealed that auditory low-frequency word lists were sensitive enough to tap the speech understanding difficulty in the simulated condition.ConclusionsThe developed word lists can be used clinically to assess communication ability in individuals with rising hearing loss. The word lists also have the potential to assess the performance after amplification provided to individuals with rising hearing loss.

Published: May 2021

BackgroundA link between musical expertise and auditory temporal processing abilities was examined.Material and MethodsTrained musicians (n=13) and non-musicians (n=12) were tested on speech tasks (phonetic identification, speech recognition in noise) and non-speech tasks (temporal gap detection).ResultsResults indicated musicians had shorter between-channel gap detection thresholds and sharper phonetic identification functions, suggesting that perceptual reorganization following musical training assists basic temporal auditory processes.ConclusionsIn general, our results provide a conceptual advance in understanding how musical training influences speech
processing, an ability which, when impaired, can affect speech and reading competency.
HIGH-FREQUENCY DISTORTION PRODUCT OTOACOUSTIC
EMISSIONS MEASURED BY TWO SYSTEMS:
AN EXAMPLE OF A SUBJECT WITH NORMAL HEARING
Authors: Pilka Edyta , Jedrzejczak W. , Olszewski Lukasz , Skarzynski Henryk 
Published: May 2021

BackgroundDistortion product otoacoustic emissions (DPOAEs) are most commonly measured up to 6 kHz. However, there
are now systems available that can measure DPOAEs up to 16 kHz. The purpose of this study was to compare two such systems.Case reportOne subject with hearing thresholds below 20 dB HL at frequencies from 0.125 to 16 kHz was used to compare
DPOAEs measured by the two systems. The HearID+DP (Mimosa Acoustics) and SmartDPOAE (Intelligent Hearing Systems)
were used. DPOAEs were measured at frequencies from 0.5 to 16 kHz. Short-time repeatability was assessed by comparing
DPOAE amplitudes between two measurements, with the second measurement made after refitting the probe. DPOAEs were
above the noise for all tested frequencies. Comparison of results from the two systems showed that the differences between
consecutive measurements and between the two systems was lowest in the 1–8 kHz range and highest in the 9–16 kHz range.
However, even in the 1–8 kHz range, differences between response levels averaged 4 dB.ConclusionsBoth systems provided DPOAE levels that were consistent with normal hearing thresholds. However, the differences between the two systems were quite high and may be too large to detect small changes in cochlear status if different
equipment is used.
ASSESSMENT OF CENTRAL AUDITORY PROCESSING DISORDER IN CHILDREN AND ADOLESCENTS TREATED WITH METHYLPHENIDATE DUE TO ATTENTION DEFICIT DISORDER: SYSTEMATIC REVIEW

Published: May 2021

BackgroundImprovement in central auditory processing (CAP) test results has been reported in children with attention deficit disorder (ADD) who have been treated with methylphenidate (MPH).ObjectiveTo determine the effect of MPH on CAP tests in school-aged children and adolescents with ADD, with or without hyperactivity.MethodsA systematic review was carried out following the Prisma methodology in The Cochrane Library, Medline, Embase, and Lilacs data bases. Randomized (RCT) and non-randomized (NRCT) clinical trials were included, involving male and female patients between 6 and 18 years old, with normal audition and intelligence and diagnosed with ADD; they were given MPH treatment and the results of CAP tests were compared to placebo or non-MPH treatment.ResultsFive studies (two RCTs and three NRCTs) reported on 187 participants of both sexes, between 6 and 15 years old, of which 135 individuals met the diagnostic criteria for ADD and 44 presented ADD with central auditory processing (CAP) disorder, with 52 individuals used as controls. MPH treatment produced an increase in the performance of the speech-in-noise test (0.38 SMD [95% CI 0.11 to 0.66] [Z = 2.7, p = 0.007]), staggered spondaic words test (0.35 SMD [95% CI 0 to 0.69] [Z = 1.95, p = 0.05]) and filtered word test, frequency pattern test, and phonemic synthesis test (0.35 SMD [95% CI 0.01 to 0.68] [Z = 2.03, p = 0.04]. Also, continuous performance tests showed a decrease in the number of errors and inattentions (–0.77 SMD [95% CI –1.17 to –0.37] [Z = 3.79, p = 0.0002]) concerning the control group. The evidence was consistent, accurate, and with low heterogeneity.ConclusionsMPH has a significant and favorable effect on the CAP tests of children and adolescents with ADD.

Published: May 2021

BackgroundDermoid cysts are benign congenital lesions occurring in about 80% in the ovaries and testicles and only in about 1.6-7% are they found in the head and neck region, mainly in the midline of the body.Case reportA rare case of congenital dermoid cyst in the central compartment of the neck is presented. It was diagnosed when the patient was 10 years old; later at age 22 the patient was re-diagnosed and qualified for surgical treatment. The paper outlines the diagnostic and therapeutic procedures performed. It demonstrates the value of appropriate tests and exclusion of other possible diseases.ConclusionsDermoid cysts are a rare disorder affecting mainly the ovaries and testicles which require detailed diagnostics as a part of differential diagnosis. In most cases, they do not cause severe symptoms and often require only simple surgical treatment.

La consistencia interna es aceptable, con una alfa de Cronbach de 0,728. Conclusiones: La escala PIH adaptada al español evalúa integralmente los comportamientos de automanejo de una persona con cáncer, y demostró validez de constructo y consistencia interna para su uso en el contexto colombiano en adultos con cáncer.
The Mississippi Valley earthquake of June 30, 1947*
Authors: Heinrich Ross R. 
Published: May 2021

Abstract
On June 30, 1947 (04h23m53s.1G.C.T.), an earthquake occurred in the Mississippi Valley near the confluence of the Meramec and Mississippi rivers a few miles south of St. Louis, Missouri. The shock reached a maximum intensity of VI (Modified Mercalli) and caused minor damage in a region about St. Louis. This earthquake occurred at a time when the Mississippi River at St. Louis was reaching the crest of one of the largest floods in history, a fact which partly accounted for the high degree of nervous reaction produced by the tremor, and which also provoked the question, “Did the flood trigger the earthquake?”
This paper reports the limited data on this earthquake and discusses the possible relations of the determined epicenter to previous local seismic activity and to geologic structure.
The conclusions reached in the paper are: (1) The earthquake originated in a basement zone of transitional structure which lies between the major regional tectonic elements. (2) There seems to be a genetic relation between this earthquake and epicenters which have been located along the Ste. Genevieve fault, on the Duquoin flexure, and on the northeastern Ozark flank. (3) The question, “Did the flood trigger the earthquake?” cannot be answered.
