Recent seismicity in the Messina area, southern Italy, and comparison to the local geology and tectonics
Authors: Neri Giancarlo , Orecchio Barbara , Pino Paolo , Presti Debora , Scolaro Silvia , Torre Antonino
Published: August 2023

We have investigated the seismicity occurred during 2000-2021 in the area of Messina, the town which suffered greatest loss of human lives over the territory devastated by the magnitude 7.1 earthquake of December 28, 1908. We have found that most of recent activity was located beneath the historical centre of the town, in and near the very peculiar sickle-shaped harbor zone which prompted the Greek colonizers in the VII Century B.C. to give Messina the old name of “Zancle”(“Sickle” in the ancient Greek language). Extracting from the whole dataset (consisting of hundred earthquakes of maximum magnitude 3.8) the data relative to a small sequence of 28 events concentrated in a few days at the end of 2013, and performing high-quality Bayesian hypocenter locations of these events, we have found very clear epi-hypocentral trends suitable for comparison with the local structural scenario. The joint analysis of seismic, geological and geomorphological data including morphobathymetric curves of the sea bottom in the study area, has brought us to propose that the small sequence in question (and probably most of activity recorded during the whole 22-years period) may have been generated by internal dynamics of a local horst/graben system, the position of which (i) appears to correspond to one of the minor horsts documented in the Messina Strait basin area and (ii) is very close to the upper edge of the 1908 earthquake blind source reported in the Database of Individual Seismogenic Sources of the Italian National Institute of Geophysics and Volcanology.

We consider a smoothly bounded q-pseudoconvex domain Ω in an ndimensional Stein manifold X and suppose that the boundary bΩ of Ω satisfies (q − P) property, which is the natural variant of the classical P property. Then, one prove the compactness estimate for the ∂-Neumann operator Nr,s in the Sobolev kspace. Applications to the boundary global regularity for the ∂-Neumann operator Nr,s in the Sobolev k-space are given. Moreover, we prove the boundary global regularity of the ∂-operator on Ω.
SOCIO-POLITICAL AND PSYCHOLOGICAL FACTORS OF AMRI ULIL IN DETERMINING THE BEGINNING OF THE HIJRI MONTH
Authors: Azis Abdul , Kholis Nur
Published: August 2023

The difference in the determination of the beginning of the Islamic month in Indonesia is not only related to differences in methods, but also related to Ulil Amri who has authority in that regard. This needs to be studied because in general Ulil Amri is understood as the holder of power, state or government. So that when there is something different from the results of the government's determination, it is considered to violate the orders of Ulil Amri. This article aims to explore the concept of Ulil Amri from several communities and organizations of Muslims in Indonesia and the background of the concept formed. Data collection was carried out by literature studies both related to the concept of Ulil Amri according to classical scholars and the concept of Ulil Amri according to several communities and organizations of Muslims in Indonesia. This study shows that the concept of Ulil Amri owned by Muslims in Indonesia comes from classical fiqh literature that refers to the government (hukkam) and ulama. The variety of Ulil Amri owned by Muslims in Indonesia also refers to these two concepts. However, there are other variants that are the development of both concepts such as Murshid Tariqah (Sufi Master) and the head of the Jamaat. The Ulil Amri type variant in Indonesia was formed due to social, religious and political backgrounds. In addition, the similarity of the methods and criteria used by the Muslim community with those used by the government also influenced the difference in the concept of Ulil Amri.

Disasters such as floods, landslides, earthquakes, and so on can cause health problems including injuries and skin disorders such as open or closed wounds to skin infections. The Manado City Government had made efforts to deal with floods and landslides through BNPB, one of which was by evacuating residents from areas prone to flooding and landslides. This study aimed to determine the factors that cause injuries in the floods and landslides that occurred in January-February 2021 in Manado City. This study was a quantitative descriptive study with non-probability sampling technique, with a total of 44 respondents. The inclusion criteria were Manado City residents and had injuries or wound due to floods or landslides. Exclusion criteria was residents who already had injuries before the disaster. The result of this study were: most respondents were in the early and late elderlies age group, were male, were inside of their houses when the disaster occurred. Most type of injuries occurred due to irritation of floodwater. It can be concluded that there was no significant relationship between age and location when the disaster occurred and the wound etiology and there was a significant relationship between gender, which was male, and wound etiology. It is recommended that residents in disaster-prone areas be given education about disaster preparedness to prevent injuries when a disaster occurred.

TIME DEPENDENT PRESSURE GRADIENT EFFECTS ON UNSTEADY MHD COUETTE FLOW THROUGH A PARALLEL POROUS PLATE
Authors:   Federal University Wukari, Wukari, Taraba State,Nigeria, Anyanwu E.O. , Raymond D. ,   Federal University Wukari, Wukari, Taraba State,Nigeria
Published: August 2023

In this paper, the unsteady MHD Couette flow through a porous medium of a viscous incompressible fluid bounded by two parallel porous plates under the influence of thermal radiation and chemical reaction is investigated. A uniform suction and injection are applied perpendicular to the plates while the fluid motion is subjected to time dependent pressure gradient. The transformed conservation equations are solved analytically subject to physically appropriate boundary conditions by using perturbation and Eigenfunction expansion techniques. The effects of some non-dimensional parameters are graphically represented and interpreted. It is observed that primary velocity is maximum when pressure gradient is time dependent as compared to when it is independent on time. Also, increase in temperature dependent pressure gradient leads to oscillation in primary velocity along distance y.

It is a must that any infrastructure built must pay attention to the aspirations, needs and problems associated with all user groups with the aim of creating a sense of security and comfort. A gender-responsive infrastructure will be considered successful if it is able to accommodate all the needs of men, women, children, the elderly, vulnerable groups equally and fairly. The existence of pedestrian paths, in addition to facilitating pedestrian access, can also be a means of city promotion which has a positive impact on improving the urban economy and reducing pollution levels due to motor vehicle exhaust emissions for better air quality. The Piere Tendean pedestrian street along the Boulevard on Business area is one of the PUPR infrastructure built by the Manado City Government. By looking at the pedestrian principle as a public space that is used for all groups, this infrastructure should have been built based on gender responsive infrastructure criteria. The evaluation was carried out using the Gender Impact Assessment (GIA) as a guide to measure the level of gender responsiveness of public works infrastructure and settlements by involving respondents from direct users of the pedestrian path. Afterwards, it was found that, in general, the pedestrian paths built did not meet the 5 (five) criteria used, so there is still a need for improvement and further development to meet gender responsive infrastructure standards.

Purpose: The purpose of this study was to examine the influence of stakeholders' management on public projects success in Kenya:

Methodology: This    study adopted a descriptive cross-sectional survey design. The target population was 500 staff working for the Kenya government. The study population included public work engineers, works clerks, public project managers, contractors, supervisors and community elder respondents. The research study embraced stratified random sampling method and a sample size of 150 respondents was obtained using the Yamane (1967) formula. The study further used structured questionnaires which consisted of both open-ended and closed-ended questions to collect data from the sampled population.  The collected data was cleaned for clarity clearness.  Coding was done on the basis of the place of the participants.  The data was analyzed using excel. Data was presented using frequency tables

Finding: The findings revealed that stakeholders’ analysis has a positive influence on public project success. Majority of the respondents agreed that stakeholders and their roles have been successfully identified. The study concludes that stakeholders’ participation had a positive impact on project success. In addition, the study suggests that proper stakeholder expectation management enhances project success.  

Unique Contribution to Theory, Practice and Policy: The study affirmed applications of stakeholder’s theory since internal and external stakeholders power determines the success of public projects. For Practice, Public Project implementors should enhance stakeholder involvement in project decision-making. There is need for improvement in participatory planning and budgeting to enhance decision-making processes.  In addition, the government should refine stakeholder management process by designing policy for stakeholder engagement. The policy, should emphasize the need to address concerns related to service timeliness, quality, and budget adherence, as well as enhancing feedback mechanisms and communication channels. Proper timeliness and quality of service delivery need to be enhanced. The government should establish mechanisms for participatory planning and budgeting, providing stakeholders with resources for active participation, addressing service timeliness and quality concerns.

Purpose: Sickle cell disease (SCD) is a common global hereditary hemoglobin disorder. One of the main treatments of sickle cell patients is the requirement of blood transfusions. Post transfusion alloimmunization of red blood cell antigens continue to be a major risk for SCD patients. The study objective is to determine the rate, nature, and risk factors of red cell alloimmunization among pediatric SCD patients in our center and compare our results to published reports from the KSA, regional and some international countries.

Methodology: A retrospective study drsign was adopted with record review of SCD patients at King AbdulAziz Medical City-Jeddah (KAMC-J) between 2008-2019 where blood samples were analyzed for alloimmunization using immunohematological techniques. Demographic characteristics and transfusion history were recorded. Data analysis was conducted by SPSS ver. 26. Data are summarized as frequency distribution and chi square test was used to check significance of the difference in the frequency of alloantibodies among subgroups.  

Findings: Out of all examined sickle cell patients (n=112). Alloantibodies were detected in 21 patients (17.4%), and these were mostly single in 15 patients (71.4%) as anti-K (23.7%), anti-E (19.0%), and anti-S (9.5%). The other six patients (28.6%) had multiple alloantibodies, especially the combination of anti-C and anti-K (9.5%) and the combination of anti-C and anti-E (9.5%). Alloantibodies were significantly higher in patients who had been admitted to the hospital > 5 times annually, those who had an exchange blood transfusion, age groups > 3 years, and for those who received a larger number of blood units (p-value < 0.05).

Recommendations: The consequences of red blood cell alloimmunization are highly significant and, therefore, extended RBC antigens to include ABO, RH (D, C, c, E, e), K, Fya, Fyb, Jka and Jkb antigens in the screening panel for donors and recipients is highly recommended to ensure better transfusion practices and avoid transfusion related complications. Our rate of alloimmunization post frequent blood transfusion is considered relatively low compared to other nations.

Purpose: The purpose of this research was to investigate the fluctuations in international tourist arrivals in Kenya and identify the underlying factors contributing to these trends. The study aimed to gain a deeper understanding of the impact of stochastic events on tourist arrivals.

Methodology: The research focused on international tourist arrivals in Kenya across seven geographical areas. It utilized annual time series data from 1980 to 2020 and examined various variables, including tourism arrivals, terrorism, political instability, conferences, and natural disasters. Descriptive statistics, the Kruskal-Wallis test, Lepage change point detection, and a Vector Autoregressive Model (VAR) with Granger causality tests were employed to analyze the data.

Findings: The findings revealed significant fluctuations in preferred destinations, source markets, purpose of visits, and length of stay among international tourists in Kenya over the study period. Major stochastic events were observed to coincide with significant changes in net arrivals, source markets, or destinations. Notably, terrorism, conferences, and the combined impact of all factors had a significant influence on net arrivals. Political instability, pandemics, and natural disasters were also found to affect international tourism arrivals.

Recommendations: Based on the results, policymakers are advised to prioritize safety and security measures to mitigate the adverse effects of pandemics and political instability on the tourism industry in Kenya. Additionally, the study recommends the development of targeted marketing strategies to attract resilient source markets. Furthermore, promoting sustainable tourism practices is essential to mitigate the long-term impact of negative events on the industry. These recommendations aim to enhance the resilience and growth of the tourism sector in Kenya.
PEMBERDAYAAN DEWAN PERWAKILAN DAERAH MEWUJUDKAN KEDAULATAN RAKYAT DI INDONESIA

Republik Indonesia sebagai negara yang memiliki jumlah penduduk yang sangat banyak dengan segala keanekaragaman mengharuskan adanya lembaga perwakilan rakyat. Wilayahnya juga sangat luas dan tersebar pada lebih dari 17.000 pulau. Diperlukan suatu sistem perwakilan rakyat yang mampu menjembatani aspirasi rakyat, agar mampu mewujudkan kedaulatan rakyat. Kedudukan rakyat dalam negara republik adalah sebagai pemegang kedaulatan rakyat.  Seluruh  macam keputusan dalam penyelenggaraan negara harus mendapat persetujuan rakyat.  Masyarakat di daerah-daerah masih belum mendapat perhatian dari pemerintah pusat sehingga menyebabkan eksodus dari daerah-daerah ke kota besar khususnya yang ada di Pulau Jawa. Potensi sumberdaya alam telah memberikan kontribusi maksimal bagi pembangunan nasional.  Sumberdaya manusia di daerah-daerah memiliki kemampuan yang belum handal terbukti banyak orang-orang yang bekerja di pusat pemerintahan maupun sektor swasta berasal dari daerah. Apapun bentuk negara, bentuk pemerintahan, maupun sistem pemerintahannya keberadaan lembaga perwakilan rakyat merupakan ruang partisipasi rakyat dalam proses penyelenggaraan negara. Rakyat Indonesia sebagai pemegang kedaulatan rakyat memerlukan ruang yang baru karena lembaga perwakilan rakyat yang ada kurang mencerminkan keterwakilan seluruh rakyat Indonesia.

Kehadiran DPD sebagai hasil Perubahan UUD 1945 yang ketiga merupakan lembaga negara baru, banyak orang yang belum tahutugas dan fungsinya.  Keberadaan DPD diharapkan memberi pengutan terhadap kedaulatan rakyat Indonesia. Rakyat Indonesia sebagai pemegang kedaulatan rakyat belum menikmati sepenuhnya apa yang diperjuangkan para pendiri negara.  Harus ada kemauan politik yang besar dari elemen politisi, anggota DPD maupun rakyat agar semua lembaga perwakilan rakyat mampu memberikan kontribusinya untuk mencapai tujuan negara, yaitu masyarakat adil dan makmur.
The Audiences of Francis Beaumont’s THE KNIGHT OF THE BURNING PESTLE
Authors: Drakakis John
Published: August 2023

This essay sets out to examine critically Beaumont’s representation of different audiences in his play The Knight of the Burning Pestle. The dominant critical tradition has it that the play is even-handed in its criticism  of audiences, but the argument here is that different audience tastes are pitted against each other. The dominant motif is that treated seriously in, for example, Spenser’s The Faerie Queene and it is this tradition and its various deployments by different social groups that is placed under scrutiny in the play. As a result it is an established dramatic form that is placed under scrutiny as different audiences seek to appropriate it for their own purposes.
