Sea ice in the Baltic Sea during 1993/94–2020/21 ice seasons from satellite observations and model reanalysis
Authors: Singh Shakti , Maljutenko Ilja , Uiboupin Rivo
Published: July 2024

Abstract. This study investigates the sea ice characteristics of the Baltic Sea using Copernicus satellite and model reanalysis data products from 1993 onwards. Our primary focus is on assessing the performance of the latest Copernicus model reanalysis product in estimating ice season evolution compared to the satellite dataset. Firstly, the model reanalysis dataset is bias-corrected for further analysis. While the model estimates an earlier start to the ice season, it generally matches satellite data regarding the season’s end. Additionally, we find that the model tends to overestimate ice thickness compared to ice chart-based data. Across the Baltic Sea, declining trends for the sea ice are observed. The sea ice statistics during the recent period (2007–2021) show decreased sea ice fraction and thickness. The decrease in the sea ice thickness is over 50 % in some areas during the melting phase. Trend analysis in the study reveals a uniform pattern towards shorter ice seasons (most prominent being in Bothnian Bay with a range of approximately 1–3 days/year of decline in ice season), reduced sea ice extent (SIE) and reduced mean ice thickness (reaching up to -0.4 cm/year).

Abstract. This study presents an updated evaluation of stratospheric ozone profile trends at Arosa/Davos/Hohenpeißenberg, Switzerland/Germany, Observatory de Haute Provence (OHP), France, Boulder, Colorado, Mauna Loa Observatory (MLO) and Hilo, Hawaii, and Lauder, New Zealand with focus on the ozone recovery period post 2000. Trends are derived using vertical ozone profiles from NOAA’s Dobson Network via the Umkehr method (with a recent new homogenization), ozonesondes, and the NOAA COHesive SBUV/OMPS satellite-based record (COH) sampled to match geographical coordinates of the ground-based stations used in this study. Analyses of long-term changes in stratospheric ozone time series were performed using the updated version (0.8.0) of the Long-term Ozone Trends and Uncertainties in the Stratosphere (LOTUS) Independent Linear Trend (ILT) regression model. This study finds a consistency of the trends derived from the different observational records, which is a key factor to the understanding of the recovery of the ozone layer after the implementation of the Montreal Protocol and its amendments that control ozone-depleting substances production and release into the atmosphere. The Northern Hemispheric Umkehr records of Aros/Davos, OHP, and MLO all show positive trends in the mid to upper stratosphere with trends peaking at ~+2 %/decade. Although the upper stratospheric ozone trends derived from COH satellite records are more positive than those detected by the Umkehr system, the agreement is within the two sigma uncertainty. Umkehr trends in the upper stratosphere at Boulder and Lauder are positive but not statistically significant, while COH trends are larger and statistically significant (within 2 sigma). In the lower stratosphere, trends derived from Umkehr and ozonesonde records are mostly negative (except for positive ozonesonde trends at OHP), however the uncertainties are quite large. Additional dynamical proxies were investigated in the LOTUS model at five ground-based sites. The use of additional proxies did not significantly change trends, but equivalent latitude reduced the uncertainty of the Umkehr and COH trends in the upper stratosphere and at higher latitudes. In lower layers, additional predictors (tropopause pressure for all stations, two extra components of Quasi-Biennial Oscillation at MLO, Arctic Oscillation at Arosa/Davos, OHP and MLO) improve the model fit and reduce trend uncertainties as seen by Umkehr and sonde.

Published: July 2024

Abstract. Small-scale ice-ocean interactions near and within grounding zones play an important role in determining the current and future contribution of marine ice sheets to sea level rise. However, the processes mediating these interactions are represented inaccurately in large-scale coupled models and thus contribute to uncertainty in future projections. Due to limited observations and computational resources, grounding zone fluid dynamics in ice sheet models are simplified, omitting potential fluid exchange across the grounding zone. Previous modeling studies have demonstrated that seawater can interact with subglacial discharge upstream of the grounding zone and recent observations appear to support this possibility. In this study, we investigate turbulent mixing of intruded seawater and glacial meltwater under grounded ice using a high-fidelity computational fluid dynamics solver. In agreement with previous work, we demonstrate the strongest control on intrusion distance is the speed of subglacial discharge and the geometry of the subglacial environment. We show that, in some cases, turbulent mixing can reduce intrusion distance, but not prevent intrusion entirely. Basal melting from seawater intrusion produces buoyant meltwater which acts as an important negative feedback by reducing near-ice thermohaline gradients. Modeled basal melt rates from seawater intrusion exceed melt rates predicted by existing sub-ice shelf melt parameterizations, which make assumptions about the structure of the near-ice boundary layer that do not hold where seawater intrudes into fresh subglacial discharge. We conclude that, during periods of slow subglacial discharge, seawater intrusion can be an important mechanism of ocean-forced basal melting of marine ice sheets.

Published: July 2024

A positive community perception of the coronavirus disease 2019 (COVID-19) vaccination program is crucial for increasing vaccination coverage and achieving herd immunity. This study aimed to identify factors influencing the acceptance of a COVID-19 booster vaccine in Indonesia. It was conducted as a cross-sectional, multicenter study using a validated questionnaire distributed online to Indonesian participants aged 18 years and older.  The questionnaire covered sociodemographic characteristics, clinical conditions of both the participants and their closest contacts, the Health Belief Model (HBM) domain, and preferences for the location of receiving a booster vaccine, as well as reasons for declining a booster vaccine. Of 1550 respondents, 78.6% had received the first COVID-19 booster dose. Sociodemographic factors influencing first booster vaccine acceptance in Indonesia included age (OR36–45 vs 18–25 years: 2.43; 95%CI: 1.13–5.24; OR>45 vs 18–25 years: 3.58, 95%CI: 1.96–6.52), length of education (OR13–16 vs <12 years: 1.34; 95%CI: 1.00–1.80; OR>16 vs <12 years: 4.15, 95%CI: 2.12–8.09), monthly income (ORIDR3,500,000 vs 1,500,000: 1.72; 95%CI: 1.19–2.49), and occupation (ORHealth workers vs not-working: 1.81; 95%CI: 1.00–3.29). Clinical aspects and HBM domains associated with booster vaccine acceptance were the presence of chronic disease (OR: 1.94; 95%CI: 1.03–3.66), previously tested positive for COVID-19 (OR: 1.90; 95%CI: 1.24–2.89), having a family member or friend who was hospitalized due to COVID-19 (OR: 1.86; 95%CI: 1.32–2.62), perceived susceptibility (OR: 1.20; 95%CI: 1.02–1.41), perceived access barriers to COVID-19 vaccination (OR: 0.52; 95%CI: 0.44–0.61), and perceived benefits of COVID-19 vaccination (OR: 1.67; 95%CI: 1.41–1.97). In conclusion, factors influencing the first COVID-19 booster vaccine acceptance in Indonesia ranged from demographic and clinical characteristics as well as HBM domains. Effective strategies to expand COVID-19 booster vaccine coverage should consider these factors to encourage participation in the vaccination program.

Authors: P.V.S.Anusha
Published: July 2024

Digital transformation is essential for industrial and manufacturing sectors, especially in conveyor belt systems. On the other hand, Innovative electronic components and software applications offer opportunities for advanced fault prediction, minimizing operational disruptions, reducing inefficiencies, and enhancing overall industrial efficiency. Efficient conveyor belt systems are crucial for industrial operations, requiring early fault detection to prevent costly downtime and ensure safety. The utilization of embedded machine learning via the Edge Impulse platform enhances data collection and spectral feature extraction using wavelet approximation. This article presents a novel methodology for predictive fault detection in conveyor belt systems employing edge machine learning. Leveraging the ESP32 microcontroller and accelerometer sensor for real-time vibration data capture, a four-layer Artificial Neural Network (ANN) model, trained on 336 feature samples, is deployed via Edge Impulse and TensorFlow scripts. TensorFlow Lite compresses the model for microcontroller integration. The ESP32 microcontroller, acting as an edge device, achieves real-time predictions with 97.5% accuracy and 0.20 minimal loss. This work promises significant strides in predictive maintenance, offering cost savings, operational reliability, and efficiency gains in industrial settings, revolutionizing maintenance strategies.

Published: July 2024

Background: Prostate cancer remains a major health concern worldwide, and postoperative recurrences are a significant challenge in its treatment. Various treatment modalities have been studied, but consensus on optimal strategies has not yet been established. This case report examines the feasibility and toxicity of stereotactic body radiation therapy (SBRT) as a therapeutic option for postoperative recurrences of prostate cancer. Case presentation: A 68-year-old man with a history of prostate cancer, initially treated with radical prostatectomy, who presented biochemical recurrence. Diagnostic imaging revealed a 9 mm nodule in the prostate bed, which was treated by SBRT guided by ultrasound visualization. The patient tolerated the treatment well, experiencing minimal genitourinary and gastrointestinal discomfort. Discussion: Multiple treatment alternatives exist for post-prostatectomy recurrence. Retrospective studies have suggested the efficacy of SBRT, although they lack robust empirical evidence. Recent investigations have highlighted the safety profile of SBRT, emphasizing the need for further exploration, particularly in image-guided radiotherapy. Conclusion: SBRT guided by ultrasound visualization emerges as a promising option for ablative treatment of postprostatectomy recurrence, offering a favorable safety profile and encouraging oncologic outcomes. Further research is needed to further clarify its role in salvage radiotherapy for localized recurrences.
Impacts of money laundering and terrorism financing: Final report
Authors: Schmidt Alicia
Published: July 2024

This report outlines a conceptual model of the social and economic impacts of money laundering and terrorism financing. Drawing on a comprehensive literature review and stakeholder interviews, it identifies possible economic, societal and sectoral impacts. Economic impacts are those that affect the economy at a macro level and include reductions in economic growth and foreign direct investment and the distortion of exchange and interest rates. Societal impacts include changes in crime levels—predicate offences which generate illicit proceeds that are then laundered, crimes financed using laundered funds and crimes attracted to areas where money laundering occurs—and the associated costs to the community. They also include the consequences of terrorism enabled by terrorism financing, including the costs of terrorist attacks and the impact on national reputation. Sectoral impacts include damage to the reputation of the financial sector and other regulated entities, the crowding out of legitimate competitors, artificial increases in prices (eg real estate prices), and lost tax revenue. Importantly, not all impacts are harmful; potential benefits of money laundering include the recovery of proceeds of crime from the enforcement of the anti-money laundering and counter-terrorism financing (AML/CTF) regime, the profitability of certain sectors that facilitate or enable money laundering, and the growth of the AML/CTF industry. Having identified these impacts, this report assesses their significance in the Australian context and sets out a path towards quantifying the impacts identified as both relevant and measurable.
Ocena funkcjonowania instrumentu rent strukturalnych w latach 2002-2007
Authors: Dudek Michał
Published: July 2024

W pracy poddano analizie ewolucję instrumentu rent strukturalnych w Polsce, oceniono jego funkcjonowanie w latach 2002–2007 oraz zidentyfikowano czynniki wpływające na zainteresowanie nim wśród badanych rolników. Wykorzystany materiał badawczy pochodził z ankiet, przeprowadzonych przez Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej – Państwowy Instytut Badawczy (IERiGŻ-PIB), na próbie 3705 indywidualnych gospodarstw rolnych oraz danych zgromadzonych przez Agencję Restrukturyzacji i Modernizacji Rolnictwa (ARiMR), Kasę Rolniczego Ubezpieczenia Społecznego (KRUS). Na potrzeby badań dokonano również analizy aktów prawnych związanych z rentami strukturalnymi i krajowych planów rozwoju obszarów wiejskich. W przeciwieństwie do wielkości środków finansowych przeznaczonych na renty strukturalne oraz tzw. kryteriów dostępu dla beneficjentów od początku wprowadzenia tego narzędzia polityki rolnej nie zmieniły się zasadnicze jego cele. Po przystąpieniu Polski do Unii Europejskiej (UE) znacząco wzrosła liczba beneficjentów, m.in. na skutek liberalizacji przepisów oraz zwiększenia budżetu. Stwierdzono występowanie zróżnicowania korzystania rolników z rent strukturalnych na poziomie regionalnym.
Marketingowe grupy producentów rolnych jako determinanta rozwoju obszarów wiejskich
Authors: Chorób Roman
Published: July 2024

W opracowaniu podjęto próbę określenia wpływu i znaczenia działań marketingowych w procesach integracyjnych zachodzących między rolnictwem a przemysłem przetwórczym. Dokonano również krótkiej charakterystyki grup marketingowych jako przykładu integracji producentów rolnych. W sferze integracji rolnictwa z przemysłem spożywczym marketing spełnia niejako dwojaką rolę: po pierwsze integruje pionowo, wzmacniając więzi, po drugie wspomaga strategię osiągania sukcesu na rynku, bez czego nie ma wystarczających korzyści atrakcyjnych dla zintegrowanych stron. Marketing w układzie pionowo zintegrowanym z wiodącą rolą przemysłu spożywczego stwarza warunki do rynkowej ekspansji, zmniejsza barierę zbytu płodów rolnych, poprawia i stabilizuje opłacalność produkcji, redukując niewydolność dochodową gospodarstw rolnych, dostarcza informacji o potrzebach konsumentów żywności i ułatwia podejmowanie decyzji strategicznych. Powstawanie grup producenckich (marketingowych), zwłaszcza w warunkach rozdrobnionego rolnictwa, jest korzystne nie tylko dla samych producentów rolnych, ale także dla całej sieci handlu hurtowego i detalicznego oraz zakładów przetwórczych.

Demonstration Method with TPACK Approach to Improve the Writing Ability of Procedure Text in Fourth Grade
Authors: Mulyanah Rizka , Maulana Farid Rizqi , Wardana Deni
Published: July 2024

The observation results reveal that the teacher did not integrate technology into all learning processes, resulting in poor writing skills among students. The researcher aimed to evaluate the efficacy of the TPACK-based demonstration approach in enhancing procedural text writing proficiency. A quasi experimental pre-test post-test control group design was employed to examine this effect. The target population for this study included all fourth grade students at SDN Kedaung Wetan 2. A sample of 40 students was selected, with 20 students from class 4A assigned to the control gorup and 20 students from class 4B assigned to the experimental group. The instrument used in this study was a written test. Data analysis was performed using the SPSS 27 program. Both the Paired Sample T-Test (Sig. (2-tailed) = 0.001) and the Independent Samples T-Test (Sig. (2-tailed) = 0.075) yielded statistically significant results (p = 0.05), indicating that the null hypothesis (Ho) can be rejected in favor of the alternative hypothesis (Ha). This suggests a significant difference between the learning outcomes of students receiving traditional instruction. Furthermore, the N-Gain Score analysis revealed an average improvement of 56% in the learning outcomes. This finding supports the notion that the TPACK integrated method has a positive influence on students ability to write procedure texts.
From Outbreak to Vaccination: An Analysis of the Commercial Property Market Reaction to COVID-19 in Malaysia

Published: July 2024

This paper examines the impact of the COVID-19 pandemic on the performance of the commercial property market in Malaysia. Differing from previous studies that focus on the first wave of COVID-19 that erupted in March 2020, we examine how the commercial property market reacted to the resurgence of COVID-19 cases and the subsequent response (lockdowns, fiscal support, and vaccination program) of the government in dealing with the threat of the COVID-19 pandemic. We find that abnormal returns of listed property companies, REITs, and hotel operators decrease following the implementation of the first nationwide lockdown. Subsequent nationwide lockdowns, however, do not exert a significant impact on abnormal returns. Moreover, we find that 1-day window abnormal returns during the first and third nationwide lockdowns increase with increases in COVID-19 cases. This suggests that investors believe in the ability of these nationwide lockdowns to slow down the spread of the COVID-19 virus. In addition, we document a positive impact of blanket loan moratorium announcements and change in vaccination rate on abnormal returns. The economic magnitude of the stock price changes in response to these announcements could be used as a reference point by policymakers and investors when faced with future pandemics of a similar scale.
Current Account Imbalances, House Prices, and Institutions
Authors: Akcay Sariye Belgin
Published: July 2024

Current account imbalances and housing price boom-bust cycles have become the defining characteristics of the pre-global financial crisis period. In the same period, it is observed that even though the developments of the economies show similar trends in many countries (e.g. an increase in credit supply, a decrease in interest rates), they have distinct characteristics (e.g. the volatility of house prices, and level of current account imbalances). Additionally, their final impacts on the economy vary to a significant degree from country to country. The institutional features of the markets (e.g. accessibility of credit information, protection of investors) have the potential to contribute to this differentiation. However, there are no studies on the effect of institutional features on the relationship between house prices and current account imbalances. The aim of this study is to examine the relationship between house prices and current account imbalances as well as the role of institutions in this relationship for 14 EU countries. To do so, a simultaneous equations model is used. The results of the empirical analysis show that in the 2007-2008 global financial crisis, there is a positive and significant relationship between house prices and current account imbalances, and institutional features have a potential role in the strength of this relationship.
Why Did House Prices Go Up During COVID-19 Pandemic? Policy-Driven or Market-Driven?
Authors: Belgin Akçay S. , Akyüz Mert
Published: July 2024

During the spread of the COVID-19 virus, governments in many countries took temporary measures to mitigate and/or remove the cost of its negative effects on both society and the economy. In Türkiye, as in many countries, the deposit banks cut mortgage interest rates. Thus, Türkiye has experienced large increases in house prices, as have many countries. Türkiye has also become the country with the highest average annual rate of house price increase among the Organisation for Economic Co-operation and Development (OECD) countries during the pandemic period. However, despite an increase in the number of studies on house prices or mortgage loans during the pandemic period, there is a research gap in terms of a comparison of the relationship between house prices and mortgage loans in the pre-pandemic and the pandemic periods compared with that on other assets or in other sectors,. This study aims to rectify this gap. To achieve this, both the Fourier Granger and the Fourier Toda-Yamamoto causality tests are used. The results indicate that there are differences in both periods of time with respect to the relationship between mortgage loans and house prices in Türkiye, and that there is a causal relationship between both factors in the prepandemic period, but not during the pandemic period.
Sovereign uncertainty
Authors: Silgado-Gómez Edgar
Published: July 2024

This paper investigates the impact and the transmission of uncertainty regarding the future path of government finances on economic activity. I first employ a data-rich approach to extract a novel proxy that captures uncertainty surrounding public finances, which I refer to as sovereign uncertainty, and demonstrate that the estimated measure exhibits distinct fluctuations from macro-financial and economic policy uncertainty indices. Next, I analyse the behaviour of sovereign uncertainty shocks and detect the presence of significant and long-lasting negative effects in the financial and macroeconomic sectors using state-of-the-art identification strategies, within the context of a Bayesian vector autoregression framework. I show that a shock to sovereign uncertainty differs from a macro-financial uncertainty shock originating from disturbances in the private sector

—while the former persistently dampens the economy in the medium run, the latter displays a short-lived response in real activity. Lastly, I study the role of sovereign uncertainty in a New Keynesian dynamic stochastic general equilibrium model augmented with recursive preferences and financial intermediaries. I find that a sovereign uncertainty shock in the model is able to capture the empirical slowdowns in economic aggregates if monetary policy decisions are directly influenced by the shock. The model also emphasizes the importance of financial frictions in transmitting the effects of sovereign uncertainty shocks and highlights the minor role played by nominal rigidities.

Published: July 2024

There is good evidence that the results of a restoration program depend largely on the landscape context. In restoration projects, it is crucial to consider the previous land uses and covers and landscape configuration as they have a significant impact on the entire process, especially seed dispersal and natural regeneration of sites. Thus, the objective of this work was to verify the effect of landscape (i.e., land use) on restoration success of total planting, seed sowing and natural regeneration sites in the Atlantic Forest biome, southeast Brazil. The methodology employed was based on demonstration units of restoration. The focus was on regenerant richness and abundance indicators, along with land use and land cover data (class area) from 2010, 2015, and 2020, obtained from the MapBiomas Project. Generalized linear models and correlation analysis were used for the study. We hypothesize that a landscape with more forest and natural regeneration cover (mosaic of agriculture and pasture) would positively affect regenerants in restored sites, which we only observed for natural regeneration treatment sites. In active restoration treatment sites, mosaic of agriculture and pasture was negatively and farming was positively associated to regenerants. We also found greater density and richness of regenerants in natural regeneration treatment sites than in seed sowing and seedling planting. The influence of the surrounding landscape, particularly mosaic, played a crucial role in this success. In addition, land use cover history, as we observed in classes in the last five and ten years, did explain regenerants in studied sites. Thus, results show that the characterization of landscape context and previous land-use history is essential to understand the limitations to succession and define cost-effective restoration strategies.
Semantic analysis of the words "Tawba" and "Dhikr" as a Qur'anic expression
Authors: Can Muhammet Berat
Published: July 2024

The word repentance, which is a Qur'anic concept, means that the individual abandons the sin and mistake he has committed, and is determined not to return again with regret. Repentance is a matter of both the world and the hereafter. While the rewards for other acts of worship will be given in the hereafter, the reward for repentance is given to the servant in this world. This reward appears as the removal of inner distress or psychological weight from the servant. The reason why the word repentance is repeated many times in the Qur'an is that Allah reminds the servant to give up his sins and to return to his covenant with repentance. In the study, the usage and semantic analysis of the words derived from the verb root (تاب) in the Qur'an are discussed. The meanings used for this word in Islamic literature are emphasized. Where the concept of repentance, which is also present in other belief systems, corresponds to the Islamic belief is explained with the verses of the Qur'an. The importance of one's repentance before the time comes, has been mentioned. For whom repentance is required, when and where repentance can be made are discussed.
Güçlü ve Zayıf Düşünceler (Ontolojiler) Arasında Kutsal Kitap
Authors: Sayın Fatma , Tatar Burhanettin
Published: July 2024

Bu makalede Eliade’ın arkaik (primitif) ontolojisini dikkate alarak, Meşşai filozofların metafiziksel (güçlü) düşünce sistemleri ve Vattimo ile Caputo’nun post-metafiziksel felsefeleri içinde kutsal kitabın nasıl konumlandırıldığını belirlemeye çalışmaktayız. Bu yazının merkezinde şu sorular bulunmaktadır: İnsan gerçekliğe şu veya bu ölçüde tanıklık etmeye çalışan bir varlık mıdır? Yoksa gerçek ile gerçek olmayanı saf haliyle birbirinden ayırabilecek bir konuma yükselebilen, dolayısıyla birbirinden farklı (zıt, çatışan) gerçeklik tasavvurları arasında sınırlar çizen evrensel hakem rolünü üstlenebilir mi? Bu sorular post-modern düşünce ile klasik ve modern metafiziksel sistemlerin birbirinden ayrıştığı noktayı gösterirler. Post-modern filozoflar en fazla gerçekliğe tanık olmaya çalışabileceğimizi, metafiziksel sistemlerin ürettiği üst anlatılarının sadece tarihsel bir yorum veya perspektifin evrensel bir üst-anlatı gibi takdiminden ibaret olduğunu ileri sürerler. Klasik ve modern metafiziksel yaklaşımlar ise insan aklının evrensel hakem konumuna yükselebileceğini kabul ederler. Bu iki yaklaşımı birbirinden ayıran en temel husus ise insanın gerçekliğe doğrudan nüfuz edip edemeyeceği sorusudur. Vattimo ve Caputo insanın gerçekliğe ancak dolaylı yani yorum (kültür, gelenek, dil vs) üzerinden erişebildiğini kabul ederken, metafiziksel felsefeler insanın gerçekliğe yorum mekânını aşarak doğrudan nüfuz edebildiğini ileri sürerler.

Importancia de la gestión logística en la rentabilidad de las empresas y la generación de valor
Authors: Ávalos Mirna Elizabeth
Published: July 2024

El presente estudio ejemplifica la relación inherente que existe entre cada una de las áreas de un negocio: ventas, compras, planificación, producción, inventarios, finanzas, contabilidad, recursos humanos, IT, etc., y la necesidad de diseñar, ejecutar y controlar herramientas que garanticen la supervivencia y rentabilidad en el largo plazo.
La mayoría de las empresas multinacionales y grandes compañías de reconocido éxito en la región tienen algo en común: una estrategia bien definida y sus procesos controlados. ¿Qué sucede con el resto de las empresas? ¿Cómo pueden competir las multinacionales, contra aquellas empresas con monopolios, o con mercados muy bien consolidados? ¿Cómo enfrentar la guerra de costos con aquellas empresas que tienen como ventaja competitiva consolidar volúmenes de compra? ¿Cómo competir contra una empresa totalmente automatizada y con tecnología de punta? ¿Cómo ser un rival importante ante una marca reconocida y con alto grado de preferencia de mercado? Y podríamos seguir enumerando una gran cantidad de cuestionamientos; sin embargo, la respuesta siempre ha estado frente a nosotros, aunque esperando en los libros, en revistas, en un salón de clases. Es en este punto donde comenzamos a ver la necesidad de poner en práctica todo ese potencial dormido, que está oculto en el talento humano de toda empresa.
La investigación propone diferentes estudios de casos de empresas en el giro de la gestión logística y su relación con la rentabilidad de las empresas y la generación de valor.

Quantifying the Criteria Used to Identify Zircons from Ore-Bearing and Barren Systems in Porphyry Copper Exploration
Authors: Carrasco-Godoy Carlos , Campbell Ian H. , Cajal Yamila
Published: July 2024

Zircon is a common mineral in igneous rocks, which is resistant to both chemical weathering and physical abrasion. Its chemistry can potentially be used to distinguish ore-forming porphyry magmas from barren magma systems. This study compiles >23,000 zircon analyses from >30 porphyry deposits, barren intrusions, and rivers to determine the principal geochemical characteristics of fertile zircons using predictive modeling, and compares them with traditional geochemical thresholds. The results show that the Eu/Eu* and Dy/Yb ratios, P content, and the curvature at the end of rare earth element (REE) patterns (λ3) are the most diagnostic characteristics of fertile zircons. The use of geochemical thresholds, as Boolean conditions, reach their maximum performance for Eu/Eu* and Dy/Yb (sensitivity [sens] = 0.73, specificity [spec] = 0.90), but it is outperformed by the random forest model (sens = 0.91, spec = 0.93) in the testing set. Explanatory analysis of the models shows that the fertility signal in zircons becomes stronger as the porphyry system evolves and is accompanied by an overall decrease in the middle to light REE and P content, characteristics that are absent in barren zircons. We attribute the observed difference in λ3 to the cocrystallization of other accessory phases, suggesting that the changes in the zircon Ce anomaly is controlled by the depletion of light and middle REE. The low P content in fertile zircons is caused by extensive crystallization of apatite. Fertile zircons have an excess of (REE + Y)3+, which we attribute to charge-balance by H+ in hydrous magmas. Simple machine learning algorithms outperform the traditional geochemical discriminators in their predictions and provide insights into characteristics that have not previously been considered for evaluating porphyry copper fertility using zircon geochemistry. We propose simplified methods that can be easily incorporated into exploration workflows.
Beyond Sanctions: ECOWAS and the Resurgence of Military Coups in West Africa
Authors: Olubiyo Kolade G. , Ayodele Iyanu-Oluwa A.
Published: July 2024

The recent resurgence of military coup d’etat in the West African region is alarming and problematic because of its contagion effect. Since 2019, Chad, Mali, Guinea, Burkina Faso and Niger have experienced military coup d’etat. As part of the efforts aimed at reversing military coups in these States, ECOWAS’ swift response has been in the form of sanctions, which include economic blockade, movement restrictions for the coup leaders, severance of diplomatic relations, and suspension of military leaders from the international community, among others. This effort has neither deterred the coup leaders nor hastened the return to civil rule. This paper attempts to examine ECOWAS’ responsibility beyond the imposition of sanctions in the era of resurgent coups in West Africa. The paper adopts the qualitative method of data collection using secondary sources, which include published books, journals, resolutions, and proceedings of ECOWAS. The paper argues that while ECOWAS is performing its moral obligation by imposing sanctions, the organisation lacks the capacity to compel West African leaders in the entrenchment of good governance. It, however, concludes that ECOWAS needs to re-strategize by having a potent framework capable of deepening good governance and stability of democracy in West Africa.
Women and Urbanisation in the Federal Capital Territory, Abuja, Nigeria
Authors: Audu Mohammed S. , Sule Hasiyah A.
Published: July 2024

This study examines women's role in the urbanisation of the Federal Capital Territory (FCT), Abuja. From the standpoint of feminist theory, urbanisation is believed to create expanded opportunities for the general populace as well as for women, who typically face discrimination in rural economies. However, the initial FCT master plan ended up being distorted by the dynamics and complexities of Abuja's urbanisation and growth process over time, which is driven by political and economic realities. There are drawbacks to urbanisation in civilisations with strong sociocultural norms and values, such as the fact that women must endure various forms of gender inequality, discrimination, and exclusion, particularly in the political sphere, which present significant difficulties. This study makes use of secondary data to demonstrate how the FCT's 2003 reconstruction to its original Master Plan provided chances for active participation in which women were included for both native people and newcomers. In a similar vein, the Federal Capital Development Authority's (FCDA) and other local council offices, which hired indigenous people for their departments and agencies, significantly altered the way of life for women from being rural farmers to empowered workers. In order to address the issues facing women in the FCT, empowerment must be a multifaceted process that transforms the economic, political, social, psychological, and legal conditions of the weak (women). It must also aim to demolish cultural, traditional, and social norms that devalue, disempower, and dispossess women, with a primary goal of meeting their needs.
