The role of siliceous sponges in pre-Eocene marine Si cycle from the perspective of rock mineralogy
Authors: Jurkowska Agata , Świerczewska-Gładysz Ewa , Kowalik Filipowicz Szymon
Published: July 2024

Abstract. The process of siliceous sponge dissolution during diagenesis was interpreted not only as an important part of marine Si cycle (comprising Si burial) but also as a significant mechanism of chert formation (so-called “chertification”; Maliva and Siever, 1989a). Both ideas were widely accepted by researches and are commonly used in geological studies. New research contradicts these seminal assumptions and indicates that in pre-Eocene marine Si cycle, although siliceous sponges were an important part of the ecosystems, did not play a controlling role in regulating dSi (= dissolved silicon) concentration in the porewater as well as in chert formation. The presented studies based on advanced mineralogical (XRD, EBSD; SEM-EDS) and microtextural (SEM) analysis of rocks and sponge remnants verify the role of siliceous sponges in the formation of Cretaceous siliceous rocks, by studying successions deposited in similar marine environments, which contain abundant fossils of siliceous sponges associated with cherts and authigenic silica polymorphs and those without them. For the first time, the mineralogical and microtextural transformations of siliceous sponge loose spicules/rigid skeletal networks, which led to their preservation as siliceous or pyrite/marcasite infillings and also in form of limonite coatings, are presented. The data presented here about the diagenesis of siliceous sponges skeletons opens the discussion on the usefulness of stable isotopic studies of δ30Si in geological studies of fossils of silicifiers preserved as secondary silica polymorphs (opal-CT).
Is drought protection possible without compromising flood protection? Estimating the maximum dual-use benefit of small flood reservoirs in Southern Germany
Authors: Ho Sarah Quỳnh Giang , Ehret Uwe
Published: July 2024

Abstract. As climate change drives intensification and increased frequency of hydrological extremes, the need to balance drought resilience and flood protection becomes critical for proper water resources management. Recent extreme droughts in the last decade in Germany have caused significant damages to ecosystems and human society, prompting renewed interest in sustainable water resources management. At the same time, protection from floods such as the catastrophic 2021 event in the Ahr Valley remain heavy in the public conscience. In the state of Baden-Württemberg in Southwestern Germany alone, over 600 small (< 1 million m3) to medium-sized (1–10 million m3) reservoirs are currently operated for flood protection. In this study, we investigate optimal reservoir operating (storage and release) rules for water supply downstream in a dual flood-drought protection scheme for 30 selected modeled flood reservoirs in Baden-Württemberg. Daily target releases for drought protection are proposed based on modeled inflows from the calibrated hydrological model LARSIM. Modified operation rules are optimized in a scenario of perfect knowledge of the future by using meteorological observations as artificial weather forecasts in LARSIM. The results of different operating rules are then evaluated based on their adherence to the target releases and flood protection performance. Reservoirs were required to maintain the same level of flood protection under these modified rules. Optimized reservoirs were able to release up to 80 times their volume or improve up to 95 % of existing drought conditions (penalty and volume deficit) over a 24-year period, though never simultaneously—there seems to be a trade-off between relative water availability to the reservoir and ability to alleviate drought conditions. Certain reservoirs were near-optimal, others could be improved further, and still others were not very effective at reducing drought conditions. We find that relative water availability at the reservoir (expressed as the number of times the reservoir can be filled by the difference between the mean inflow and mean low flow) has a strong relation to the amount of water a reservoir can release for drought protection, but fails to summarily describe the reservoir’s potential impact on drought conditions downstream.
A microbially-driven and depth-explicit soil organic carbon model constrained by carbon isotopes to reduce equifinality
Authors: Van de Broek Marijn , Govers Gerard , Schrumpf Marion , Six Johan
Published: July 2024

Abstract. Over the past years, microbially-driven models have been developed to improve simulations of soil organic carbon (SOC), and have been put forward as an improvement to assess of the fate of SOC stocks under environmental change. While these models do include a better mechanistic representation of SOC cycling in comparison to cascading reservoir-based approaches, the complexity of these models implies that data on SOC stocks are insufficient to constrain the additional model parameters. In this study, we constructed a novel depth-explicit SOC model (SOILcarb) that incorporates multiple processes influencing the δ13C and Δ14C values of SOC and assessed if including data on the δ13C and Δ14C value of SOC during parameter reduces model equifinality, the phenomenon that multiple parameter combinations lead to a similar model output. To do so, we used SOILcarb to simulate depth profiles of total SOC and its δ13C and Δ14C values. The results show that when the model is calibrated based on only SOC stock data , the residence time of subsoil organic carbon (OC) is not simulated correctly, thus effectively making the model of limited use to predict SOC stocks driven by, for example, environmental changes. Including data on δ13C in the calibration process reduced model equifinality only marginally. In contrast, including data on Δ14C in the calibration process resulted in simulations of the residence time of subsoil OC consistent with measurements, while reducing equifinality only for model parameters related to the residence time of OC associated with soil minerals. Multiple model parameters could not be constrained even when data on both δ13C and Δ14C were included. Our results show that equifinality is an important phenomenon to consider when developing novel SOC models, or when applying established ones. Reducing uncertainty caused by this mechanism is necessary to increase confidence in predictions of the soil carbon – climate feedback in a world subject to environmental change.

Abstract. The evaluation of global chemistry-climate/transport models in the upper troposphere – lower stratosphere (UTLS) is a important step towards a better understanding of the chemical composition near the tropopause, and therefore towards a more accurate assessment of the impact of NOx emissions in this region of the atmosphere, notably by subsonic aviation. For this purpose, the current study focuses on an evaluation of long-term simulations from five global models based on in-situ measurements on board passenger aircraft (IAGOS). Most simulations span over the 1995–2017 time period, and follow a common protocol among the models. The assessment focuses on climatological averages of ozone (O3), water vapour (H2O), carbon monoxide (CO), and reactive nitrogen compounds (NOy). In the extra-tropics, the models reproduce the seasonality of ozone, water vapour and NOy in both the upper troposphere (UT) and the lowermost stratosphere (LS), but none of them reproduces the CO springtime maximum in the UT. The tropospheric tracers (CO and H2O) tend to be underestimated by the models, which is consistent with an overestimation of the cross-tropopause exchange, but does not exclude other factors as an underestimation of CO emissions, an underestimation of transport from the surface, or an overestimated CO oxidation by the hydroxyl radical (OH). Ozone is systematically overestimated in the UT by most models, and the NOx background appears as the main contributor to the ozone variability across the models. The partitioning between NOy species changes drastically across the models, and acts as a source of uncertainty on the NOx mixing ratio and on its impacts on atmospheric composition and particularly on the response to aviation NOx emissions. However, independently on the mean biases, we highlight some well-reproduced geographical and seasonal distributions, as the ITCZ seasonal shifts above Africa, the upper-tropospheric H2O maximum in the Asian summer monsoon, and the extratropical ozone (H2O) in the LS (UT) that show a high correlation with the observations. These features are encouraging regarding the simulated dynamics in both the troposphere and the stratosphere. The current study confirms the importance of an accurate separation between the UT and LS using a dynamical tracer for model results evaluation but also for model intercomparisons.
Relationships between the concentration of particulate organic nitrogen and the inherent optical properties of seawater in oceanic surface waters
Authors: Fumenia Alain , Loisel Hubert , Reynolds Rick Allen , Stramski Dariusz
Published: July 2024

Abstract. The concentration of particulate organic nitrogen (PON) in seawater plays a central role in ocean biogeochemistry. Limited availability of PON data obtained directly from in situ sampling methods hinders development of thorough understanding and characterization of spatio-temporal variability of PON and associated source and sink processes within the global ocean. Measurements of seawater inherent optical properties (IOPs) that can be performed over extended temporal and spatial scales from various in situ and remote-sensing platforms represent a valuable approach to address this gap. We present the analysis of relationships between PON and particulate IOPs including the absorption coefficients of total particulate matter, ap(λ), phytoplankton, aph(λ), and non-algal particles, ad(λ), as well as the particulate backscattering coefficient, bbp(λ). This analysis is based on an extensive field dataset of concurrent measurements of PON and particulate IOPs in the near-surface oceanic waters and shows that reasonably strong relationships hold across a range of diverse oceanic and coastal marine environments. The coefficient ap(λ) and aph(λ) show the best ability to serve as PON proxies over a broad range of PON from open ocean oligotrophic to coastal waters. The particulate backscattering coefficient can also provide a good proxy of PON in open ocean environments. The presented relationships demonstrate a promising means to assess PON from optical measurements conducted from spaceborne and airborne remote-sensing platforms and in situ autonomous platforms. In support of this potential application, we provide the relationships between PON and spectral IOPs at light wavelengths consistent with those used by satellite ocean color sensors.
Hydrographic section along 55° E in the Indian and Southern oceans

Published: July 2024

Abstract. A hydrographic section along 55° E, south of 30° S, was visited from December 2018 to January 2019 as the first occupation under the Global Ocean Ship-based Hydrographic Investigation Program. The water column was measured from the sea surface to 10 dbar above the bottom with eddy-resolving station spacings and the state-of-the-art accuracy. The upper profile was characterised by a conspicuous front between 42.5° and 43° S and a cold-core eddy at 39° S. The front was identified as the confluence of Subtropical and Subantarctic fronts. The Agulhas Return Current front was found at 41.6° S. When combined with the section north of 30° S observed in 2018, another subsurface front was found in dissolved oxygen around 28° S at depths of 1500 to 3000 dbar. In the eastern Weddell-Enderby Abyssal Plain, no obvious mean flow was observed at depths greater than 3000 dbar. We used transient tracers to estimate isopycnal diffusivity there to be 72±16 m2 s-1. Antarctic Bottom Water in the basin consisted of water masses originating from the Cape Darnley region (0–35 %) and Weddell Sea Deep Water (5–75 %), diluted by Lower Circumpolar Deep Water above. These snapshot observations not only confirm hydrographic features reported earlier in the Madagascar and Crozet Basins, but also describe the diffusive nature of the deep to bottom circulation in the Weddell-Enderby Abyssal Plain. Some of the stations in the Crozet Basin were sampled in the 1980s and 1990s. Changes in the temperature-salinity relationship since then indicate warming of Upper Circumpolar Deep Water, volume reduction of Antarctic Bottom Water, and slight freshening which is stronger southward.
A hyperspectral and multi-angular synthetic dataset for algorithm development in waters of varying trophic levels and optical complexity
Authors: Pitarch Jaime , Brando Vittorio Ernesto
Published: July 2024

Abstract. This data paper outlines the development and structure of a synthetic dataset (SD) within the optical domain, encompassing inherent and apparent optical properties (IOPs-AOPs) alongside associated optically active constituents (OACs). The bio-optical modeling benefited from knowledge and data accumulated over the past three decades, resulting on a comprehensive dataset of in situ IOPs, including diverse water typologies, and enabling the imposition of rigorous quality standards. Consequently, the bio-optical relationships delineated herein represent valuable contributions to the field. Employing the Hydrolight scalar radiative transfer equation solver, we generated above-surface and submarine light fields across the specified spectral range at a “true” hyperspectral resolution (1 nm), covering the ultraviolet down to 350 nm, therefore facilitating algorithm development and assessment for present and forthcoming hyperspectral satellite missions. A condensed version of the dataset tailored to twelve Sentinel-3 OLCI bands (400 nm to 753 nm) was crafted. Derived AOPs encompass an array of above- and below-surface reflectances, diffuse attenuation coefficients, and average cosines. The dataset is distributed in 5000 files, each file encapsulating a specific IOP scenario, ensuring sufficient data volume for each water type represented. A unique feature of our dataset lies in the calculation of AOPs across the complete range of solar and viewing zenith and azimuthal angles as per the Hydrolight default quadrants, amounting to 1300 angular combinations. This comprehensive directional coverage caters to studies investigating signal directionality, previously lacking sufficient reference data. The dataset is publicly available for anonymous retrieval via the FAIR repository Zenodo at https://doi.org/10.5281/zenodo.11637178 (Pitarch and Brando, 2024).

Abstract. A historic rainstorm occurred over Henan, China, in July 2021 (“7.20” extreme precipitation event), resulting in significant human casualties and socioeconomic losses. A global variable-resolution model (MPAS-Atmosphere v7.3) was employed to simulate this extreme precipitation event. A series of simulations have been done at both quasi-uniform (60 and 15 km) and variable-resolution (60–15 and 60–3 km) meshes from hydrostatic to nonhydrostatic scale with two parameterization scheme suites. For the 48 h peak precipitation duration (20–22 July), the 60–3 km variable-resolution simulation coupled with the scale-aware convection-permitting parameterization scheme suite stands out predominantly among other simulation experiments as it reproduces this extreme precipitation event most accurately. At 15 km resolution, the 60–15 km variable-resolution simulation achieves comparable forecasting skills to the 15 km quasi-uniform simulation but at a much reduced computing cost. In addition, we found that the default mesoscale suite generally outperforms the convection-permitting suite at 15 km resolution as simulations coupled with the convection-permitting suite missed the third peak of this extreme precipitation event, while the mesoscale suite did not. Furthermore, it is found that the large-scale circulation plays a critical role in the peak precipitation simulations at 15 km resolution, via influencing the simulated low-level wind. During the second peak precipitation period, simulations with the convection-permitting parameterization scheme suite at 15 km resolution generate a prominent low-level easterly wind component bias, which is largely attributed to the excessively evaporative cooling in the lower troposphere. This study further reveals that at 15 km resolution the diabatic heating from the grid-scale precipitation accounts more for the low-level wind bias than the convective-scale precipitation. Given that two different cloud microphysics schemes, namely Thompson and WSM6 schemes, are used in the convection-permitting and default mesoscale parameterization scheme suites, respectively, these microphysics schemes are found to be the primary contributor to the low-level wind simulation bias.
Evaluation of Dust Emission and Land Surface Schemes in Predicting a Mega Asian Dust Storm over South Korea Using WRF-Chem (v4.3.3)

Published: July 2024

Abstract. This study evaluates the performance of the Weather Research and Forecasting Model coupled with Chemistry (WRF-Chem) in forecasting a mega Asian Dust Storm (ADS) event that occurred over South Korea on March 28–29, 2021. We specifically evaluated a combination of five dust emission schemes and four land surface schemes, which are crucial for predicting ADSs. Using in-situ and remote sensing data, we assessed surface meteorological and air quality variables, including 2 m temperature, 2 m relative humidity, 10 m wind speed, particulate matter 10 (PM10), and aerosol optical depth (AOD) over South Korea. Our results indicate that prediction of surface meteorological variables is more influenced by the land surface scheme than by the dust emission scheme—generally showing good performance when dust emission schemes are combined with the Noah land surface model with Multiple Parameterization options (Noah-MP). In contrast, prediction of air quality variables, including PM10 and AOD, is strongly affected by the dust emission schemes, which is directly related to the generation and amount of dust through interaction with surface properties. Among the total of 20 available scheme combinations, the University of Cologne 2004 combined with the Community Land Model version 4.0 (UoC04-CLM4) showed the best performance, closely followed by the University of Cologne 2001 combined with CLM4 (UoC01-CLM4). UoC04-CLM4 outperformed the other scheme combinations by reducing the root mean square errors of PM10 up to 29.6 %. However, both UoC04-CLM4 and UoC01-CLM4 simulated values closest to the MODIS AOD but tended to overestimate the AOD in some regions during the origination and transportation processes. In contrast, other scheme combinations significantly underestimated the AOD throughout the entire simulation process of ADSs.

Published: July 2024

The prevalence of human immunodeficiency virus (HIV) among adolescents is on the rise due to a lack of comprehensive knowledge, leading to suboptimal attitudes and behaviors, which emphasizes the critical need for targeted interventions. The aim of this review study was to evaluate the effectiveness of educational interventions for HIV prevention among adolescents by assessing their impact on knowledge, attitude, and behavior. A systematic review of seven databases: PubMed, Science Direct, Cochrane, JSTOR, Embase, Scopus, and EBSCO were identified, and 14 eligible randomized controlled trials published until June 2023 were included. Two independent authors assessed quality appraisal using the Risk of Bias 2.0. Outcomes were measured using the standard mean difference (SMD) with random effects model and a 95% confidence interval. Subgroup analyses and meta-regression were performed to explore heterogeneity. The results showed significant improvements in participants' knowledge (SMD: 1.13, 95%CI: 0.78–1.49), behavior intentions (SMD: 1.22, 95%CI: 0.37–2.07), and attitude (SMD: 0.48, 95%CI: 0.02–0.95) after receiving HIV prevention education programs. Interventions grounded in theoretical principles and incorporating technology, group settings, and audio-visual aids were found to be effective in enhancing knowledge of HIV prevention and promoting behavioral intentions. Peer-led education positively impacted both knowledge and attitude. Moreover, excluding parents from these programs was identified as a crucial factor in improving adolescents' knowledge of HIV prevention. In conclusion, educational programs focused on HIV effectively enhance adolescents' knowledge, attitudes, and behavioral intentions among adolescents. Professionals planning interventions should consider these impactful components in designing comprehensive strategies.

Published: July 2024

Geotechnical assessment of lateritic soils obtained from along the Ojota and Shagamu ends of the Lagos–Ibadan expressway was conducted to evaluate their suitability for use as sub-grade and sub-base materials. Laboratory tests, including moisture content, specific gravity, particle size distribution, fabric/plasticity, compaction, and California Bearing Ratio (CBR), were performed on eight (8) soil samples following British Standards (BS) 1377 methods for soil testing. The lateritic soils were classified as clayey sand, silty clay, and silty to clayey sand. They exhibited moderate plasticity and semi-pervious characteristics, suggesting suitability for use as sub-grade materials. Samples 3, 5, 7, and 8 were identified as more suitable for road construction materials, while Samples 1, 2, 4, and 6 showed susceptibility to seasonal volume changes due to high clay content. These samples would require minor soil stabilization to mitigate the effects of their active clay contents. Adequate drainage systems were recommended to prevent water accumulation, soil volume changes, loss of load-bearing capacity, and potential material failure beneath road pavements. The geotechnical properties of the lateritic soils from the tropical area of Ojota–Shagamu differed significantly from those of other lateritic soils found in southwestern Nigeria.

Copper and Iron Make the Difference: Developing Sustainable Photoredox Catalyzed Transformations
Authors: Reiser Oliver
Published: July 2024

Synthetic organic chemistry undertakes significant efforts to develop new catalytic transformations that utilize greener reagents and avoid stoichiometric additives. In this regard, visible-light photoredox catalysis offers a unique activation mode of molecules, which serves as an alternative to many thermal transition-metals catalyzed reactions. Most photoredox-catalyzed processes capitalize on heavy metals, namely, Ru(II) or Ir(III)-complexes, which can serve as single electron oxidants or reductants in their photoexcited states. Copper-and iron-based photo¬catalysts are rapidly emerging, offering economic and ecologic advantages but, in addition, can interact with substrates beyond electron transfer via inner sphere mechanisms, which have been successfully utilized to achieve challenging transformations. Emphasizing the principles of photoredox catalysis, selected synthetic applications from our laboratory will be discussed, highlighting the opportunities copper- and iron-photocatalysts offer in this area.

Published: July 2024

This research is motivated by the phenomenon related to the implementation of the Population Identity Digital Application in Jember Regency. Where in Jember Regency the application of the Population Identity Digital Application is still uneven. Of the 31 sub-districts in Jember Regency, only 8 sub-districts can activate this application. One of them is Tempurejo District. This is because there is one employee who has an attachment to the Jember Regency Dispendukcapil so that Tempurejo District is the centre of activation of the Population Identity Digital Application between 2 sub-districts including; Ajung and Jenggawah. So the researcher aims to find out the description of the Implementation of the Population Identity Digital Application in Tempurejo District, Jember Regency. Qualitative methods were used by researchers in this study where qualitative approaches and models can better explore problems that arise from social phenomena of population services and. The results showed that the Tempurejo District Government was influenced by two factors. Among them; Communication Factors and Human Resources Aspects. In the Communication Factor, Tempurejo Sub-district has not conducted socialisation related to the Digital Identity Population application. In the HR factor, only one employee understands in conducting public services with the Digital Population Identity application. So that I as the author provide advice to the Jember district government to overcome these two factors. So that all sub-districts in Jember Regency can activate the Digita Population Identity Application and also the people of Jember Regency understand about the Digital Population Identity application.

Being with uncertainty: A reflective account of a personal relationship with an asylum seeker/refugee
Authors: Morrison David T.
Published: July 2024

Background:
Violent political instability in countries such as Syria has seen the worldwide number of forcibly displaced people rise to levels not seen since World War 2, with over 150,000 asylum seekers and refugees hosted in the UK alone (UNHCR, 2015). Despite this figure, many UK residents have only a limited understanding of the experience of seeking asylum.

Content & Focus:
This article features a reflective account of the author’s experience of being in a relationship with an asylum seeker/refugee in the UK. It begins with the author’s reflections on the harsh asylum process and encourages those of us with a right to remain in the UK to consider how we would cope in such circumstances. Opportunities for personal and professional development that have arisen from the relationship are outlined, with particular emphasis on the experience of uncertainty and powerlessness. Finally, indignation at the inequalities faced by asylum seekers and refugees is presented as a catalyst for the development of a social justice agenda both within and beyond the therapy room.

Conclusion:
Being in a romantic relationship with an asylum seeker/refugee offers a unique vantage point to learn about the asylum process in depth. Furthermore, even such overtly challenging experiences can be transformed into opportunities for personal and professional growth, including the development of a social justice agenda in our counselling psychology practice.
How should counselling psychologists investigate their practice in an era of volatility?
Authors: Corrie Sarah , Lane David A.
Published: July 2024

Content and Focus:
Counselling psychologists offer their services to clients in organisational, political and economic contexts that are characterised by increasing levels of complexity, uncertainty and turbulence. Investigating the effectiveness of what we do remains critical to the future of the psychology professions, but our traditional approaches to scientific enquiry may not be adequate for the types of dilemma generated by complexity.

Conclusions:
This paper describes a framework, adapted from contemporary complexity theory, that can support us in thinking systematically and creatively about the range of investigative skills we might need if professional practice is to prove fit for purpose in the decades to come. It is proposed that complexity theory can assist us in responding creatively to the dilemmas of living and working in unprecedented times.

O presente artigo, desenvolvido no âmbito do Programa de Pós-graduação Strico Sensu em Direito da UNIJUÍ, com área de concentração em Direitos Humanos, visa traçar um paralelo entre o capitalismo neoliberal patriarcal e predatório, analisado a partir do filme de Martin Scorsese “O Lobo de Wall Street”, e a política dos comuns, descrita a partir do feminismo anticapitalista de Silvia Federici. A relevância do tema se dá pelo contexto socio-cultural no qual estamos inseridos, e apesar do filme “O Lobo de Wall Street” datar de 2013, permanece atual e relevante no cinema. O questionamento trazido é: que alternativas existem à ideologia moral regida pela masculinidade capitalista predatória? Para responder tal questionamento, o artigo se estrutura em duas seções: a primeira delas retrata a ideologia moral do capitalismo caracterizada a partir de uma análise do filme de Martin Scorsese “O Lobo de Wall Street”, dentro do contexto da economia libidinal retratada no ambiente patriarcal e machista do mundo financeiro. Na sequência, traz a política dos comuns descrita pela lente feminista de Silvia Federici, que retrata uma forma de feminismo anticapitalista, o qual, para Federici, constitui a base da política dos comuns e coloca no horizonte uma nova (e antiga) forma de produção e distribuição de riquezas, compassiva com a vida de todos os seres humanos e compatível com a preservação do planeta. Ressalta-se que o uso do cinema e das artes sempre teve uma relação com a educação em Direitos Humanos, sendo um dos objetivos do artigo demonstrar como realizar esse paralelo no âmbito acadêmico. Para tanto, o método de pesquisa empregado foi o hipotético-dedutivo, por meio da pesquisa documental e bibliográfica.
Analisis hukum ketenagakerjaan terkait pemenuhan hak pekerja/buruh dalam pemutusan perjanjian secara sepihak oleh perusahaan
Authors: Safrida
Published: July 2024

Suatu hubungan hukum timbul karena adanya hak dan kewajiban, dalam hal itu maka suatu hubungan kerja merupakan hubungan perdata yang didasarkan pada kesepakatan antara pekerja dengan pengusaha, dengan adanya hak dan kewajiban yang harus dijalankan oleh masing-masing pihak. Hak dan kewajiban masing-masing pihak itu selanjutnya dituangkan dalam perjanjian kerja. Dalam hubungan kerja tidak hanya ada diskriminasi pekerjaan satu sama lain tetapi juga terdapat masa berlakunya suatu pekerjaan atau jangka waktu yang telah di tetapkan atau di sepakati di dalam perjanjian  kerja, namun tidak menutup kemungkinan sebelum berakhirnya perjanjian tersebut pekerja/buruh dapat dilakukan pemutusan hubungan kerja (PHK) oleh pengusaha. Penelitian ini menggunakan jenis penelitian hukum normatif yang bersumber dari data sekunder yang berkaitan dengan topik penelitian, data sekunder yang telah disusun secara sistematis kemudian dianalisis secara kualitatif. Dari penelitian yang dilakukan ditemukan bahwa sebelum melakukan perjanjian terlebih dahulu melihat keabsahan dalam suatu perjanjian yang sudah tertuang di dalam pasal 1320 KUHPerdata yang menjelaskan bahwa syarat sahnya suatu perjanjian adalah sebagai berikut Sepakat mereka yang mengikatkan dirinya, Cakap untuk membuat suatu perikatan, Suatu hal tertentu dan Suatu sebab yang halal. Pekerja/buruh juga mempunyai hak yang terdapat dalam aturan tersebut. Menurut Undang-Undang Ketenagakerjaan : Menjadi Anggota Serikat Tenaga Kerja (UU Nomor 13 tahun 2003 Pasal 104), Jaminan sosial dan Keselamatan Kesehatan Kerja (K3), Menerima Upah yang Layak, Membuat Perjanjian Kerja atau PKB, Hak Atas Perlindungan Keputusan PHK Tidak Adil, Hak Karyawan Perempuan seperti Libur PMS atau Cuti Hamil, Pembatasan Waktu Kerja, Istirahat, Cuti dan Libur. Pemutusan Hubungan Kerja sepihak yang dilakukan oleh pengusaha bisa mengakibatkan perselisihan antara Pekerja/Buruh dan Pengusaha atas tindakan PHK yang dilakukan secara sewenang-wenang serta hak-hak pekerja yang harusnya di berikan tidak sesuai dengan apa yang di berikan pengusaha dan sangat merugikan bagi Pekerja/Buruh tersebut. PHK tersebut merupakan salah satu bentuk ketidakadilan demi kepentingan Pengusaha/Perusahaan serta menjadikan pekerja/buruh sebagai korban atas ketidakberdayaan terhadap para pengusaha

A Critical Analysis of the Standard Urban Model in the Context of Greater Manchester
Authors: Wang Shu
Published: July 2024

This study critically examines the applicability of the Standard Urban Model (SUM) in the context of Greater Manchester, utilizing empirical data and spatial analysis to explore its operational limitations and potentials. Originally conceptualized by William Alonso, the SUM provides a theoretical framework to understand intra-urban economic dynamics predicated on a monocentric city structure. Through a comprehensive dataset encompassing census demographics, housing prices, and GIS-mapped land-use patterns from 2015, this paper investigates the models ability to predict and describe urban land rent gradients and residential distribution relative to the citys Central Business District (CBD). The findings indicate that while the SUM may provide a generalized view of urban structure, it significantly underestimates the socio-economic diversities, technological advancements, and cultural influences that are inherent in urban development. Particularly, the analysis reveals that rental price declines with distance from the CBD are not as pronounced as predicted by the SUM, with a low coefficient of determination (R=0.2551). Furthermore, the study highlights how urban development in Manchester deviates from the monocentric model due to historical shifts, regeneration efforts, and the emergence of multi-centric hubs. This research underscores the necessity for adapting urban economic models to reflect the complexities and dynamic nature of modern cities, suggesting a shift towards more nuanced and flexible frameworks that accommodate the multifaceted influences on urban landscapes.
