Authors: Chea John D. , Conway Matthew , Ruiz-Mercado Gerardo J. , Benavides Pahola Thathiana , Yenkie Kirti M.
Published: August 2024

Plastics are widely used for their affordability and versatility across many consumer and industrial applications. However, the end-of-life (EoL) management stage can often lead to releasing hazardous chemical additives and degradation products into the environment. The increasing demand for plastics is expected to increase the frequency of material releases throughout the plastic EoL management activities, creating a challenge for policymakers, including ensuring proper material segregation and disposal management and increasing recycling efficiency and material reuse. This research designed a Python-based EoL plastic management tool to support decision-makers in analyzing the holistic impacts of potential plastic waste management policies. The constructed tool was developed to reduce the complexity of material flow analysis calculations, estimating material releases, and environmental impacts. The utility of the tool was tested through the hypothetical nationwide adoption of an extended producer responsibility (EPR) program. The decision-making capability of the tool can facilitate the prediction of long-term outcomes, offering technical knowledge and insight for policymakers seeking to mitigate the environmental and health impacts of plastic pollution.

Published: August 2024

Post-combustion carbon capture technologies have the potential to contribute significantly to achieving the environmental goals of reducing CO2 emissions in the short term. However, these technologies are energy and cost-intensive, and the variability of flue gas represents important challenges. The optimal design and optimization of such systems are critical to reaching the net zero and net negative goals, in this context, the use of computer-aided process design can be very effective in overcoming these issues. In this study, we explore the implementation of carbon capture technologies within an industrial complex, by considering the pooling of CO2 streams. We present an optimization formulation to design carbon capture plants with the goal of enhancing efficiency and minimizing the capture costs. Capital and operating costs are represented via surrogate models (SMs) that are trained using rigorous process models in Aspen Plus, each data point is obtained by solving an optimization problem in Aspen Plus equation-oriented approach. Since selecting the functional form of the surrogate model is crucial for the solution performance; we study different SM approaches (i.e., ALAMO, kriging, radial basis function, polynomials, and artificial neural networks) and analyze their impact on solver performance. Numerical results show the computational advantage of using ALAMO while highlighting the increased complexity of using ANN and kriging to formulate optimization problems. Regarding the pooling of CO2 streams, the optimal designs for the network are not trivial, thus showing the importance of addressing the problem systematically.

Authors: Lu Ruokai , Wei Dianlin
Published: August 2024

Under the background of the current national unity and the integration of culture and
tourism, this paper deeply explores the development dilemma of ethnic minority festival activities,
reveals the dynamic relationship between ethnic minority festival activities and social structure, and
then identifies the root causes of its development dilemma, and seeks to promote its contemporary
inheritance and development through brand design. Using literature analysis and theoretical
analysis, this paper systematically combs the historical evolution, current situation and challenges
of ethnic minority festival activities. Especially in the perspective of ritual theory, in-depth analysis of
the cultural connotation and social function of national festivals, as well as its adaptation and
change in contemporary social changes. The study found that due to the changes in the social
structure, the fracture of cultural heritage and the intensification of external competition, the current
ethnic minority festival activities are facing problems such as insufficient inheritance, low popularity
and weakening of festival activities. By creating a festival brand with local characteristics and
cultural connotation, it can stimulate national pride and cultural identity, promote the integration and
development of national unity and cultural tourism industry, reconstruct the social foundation of
ethnic festival activities, and enhance their cultural value and market influence. Therefore, we
should actively explore and practice the application of brand design in ethnic minority festivals, and
make positive contributions to the protection and inheritance of traditional culture of ethnic
minorities.

Published: August 2024

Writing this article aims to find out the history of Dutch heritage in the village of Sukadana, East Lampung. The method used is qualitative with a naturalistic paradigm. The research instruments are observation, interview guides, and researchers as key instruments. The data source for this research is the results of interviews with cleaning service officers at the puskesmas, village youth leaders and post office leaders. The result is that East Lampung Regency is one of the regencies resulting from the division in 1999. Sukadana is used as a place of transmigration or transfer of people or communities from Java. This migration or also known as colonization was carried out for the first time in November 1905 by bringing the first batch of colonization groups from Bagelen, Kedu Residency, Central Java, which were then placed in Gedong Tataan. The Dutch East Indies government moved people from Java and placed them in almost all areas in Lampung. This policy continued until 1979. As long as the Dutch Government was in Sukadana village they left several traces of historic buildings for the Sukadana community. These buildings include, namely, the old well, the staircase building, the head of state's building, and the post office. As well as the buildings on the Tamiang hill.

How Belonging to a Minority Group, Receiving a Hiring Decision and Getting Feedback on Test Results Affect the Intention to File a Complaint: The Mediating Role of Perceived Discrimination in Hiring
Authors: Denis Pascale L. , Cossette Michel , Stamate Alina N. , Haeck-Pelletier Justine , Sauvé Geneviève
Published: August 2024

Objective indicators, such as minority hiring rates or number of complaints, often fail to fully represent actual discrimination in hiring processes, particularly against racial and ethnic minorities (McGonagle et al., 2016). Despite legal efforts in Quebec to increase employment of minorities, their ongoing underrepresentation points to the need to examine discrimination in terms of perceived experiences. In line with Anderson (2011), we investigated perceived discrimination in hiring (PDH), its predictors and its effect on the intention to file a discrimination complaint, rather than solely considering actual complaints. Using a quasi-experimental design, we simulated a fictitious hiring process with 361 students from French-speaking Canadian universities. First, we confirmed the three dimensions of the recently developed PDH scale: differential treatment; breach of psychological contract; and non-competency-based assessment (Haeck-Pelletier, 2022). Second, using structural equation modelling (SEM), we found mediation effects: PDH scores were higher across all dimensions when a candidate belonged to a minority group, received a negative hiring decision or did not receive feedback on test results. However, only differential treatment predicted a candidate’s intention to file a complaint. In addition to this first empirical test of Anderson’s model, the results suggest that organizations should address perceptions of unfair treatment due to minority group membership by identifying and modifying the practices that contribute to them. The eventual outcome would be a more representative workforce.
Employee Turnover and Company Value. Were European Companies Equally Affected by the COVID-19 Pandemic?
Authors: Garsaa Aziza
Published: August 2024

In this study, we sought to identify how employee turnover affected company value in a sample of 254 European listed companies before and during the COVID-19 pandemic. We specifically tested the hypothesis that the most profitable and socially responsible companies withstood the pandemic better. We then complemented our analysis by identifying potential sectoral differences.

We analyzed the association between employee turnover and company value by using a quantile regression model to determine this association at each point of the conditional distribution of company value. All of our financial and non-financial data for the 2019-2020 period were extracted from the Bloomberg database.

We found a negative association between employee turnover and company value before and during the pandemic. The additional costs of employee turnover may have therefore reduced stock market values. The negative association weakened considerably during the pandemic for those companies that had the lowest company value, possibly because of the government support and guarantees they received during the lockdowns. Our sectoral analysis showed a stronger effect on traditional industries with intensive human interactions than on modern industries with predominantly virtual interactions. Estimation results from more profitable companies showed a positive association before the pandemic, perhaps because they had an ‘optimal’ level of employee turnover that maximized their productivity and performance and, thus, their stock market value. This association completely reversed during the pandemic, perhaps because their higher profitability was not sufficient to dampen the negative effect of the increase in employee turnover. For the most profitable and socially responsible companies, the same association was much stronger both before and during the pandemic. For almost all of the companies, the estimated coefficients of employee turnover were positive before the pandemic but became negative for those companies that had the lowest stock market values during the pandemic.

This study enriches the existing literature by being the first one to show how employee turnover affected the company value of European listed firms before and during the pandemic. It also provides new evidence that this association varied with the level of sectoral sensitivity to the pandemic and was much stronger for the most profitable and socially responsible companies.

Published: August 2024

Cet article vise à étudier les conséquences sociales des relations industrielles de la sous-traitance internationale qui, si elle est source de compétitivité pour les grandes entreprises dans les pays développés, peut conduire à des conditions de travail indécentes dans les pays en développement, en particulier dans les industries à forte intensité de main-d'oeuvre. Nous abordons la question peu explorée de la nature de l'engagement des PME du textile au Maroc en matière de responsabilité sociale compte tenu des exigences des grands donneurs d’ordres. Les résultats de notre étude quantitative corroborent l'hypothèse d'une dégradation des conditions de travail des salariés qui accompagne la sous-traitance internationale.
Exploring Youth Preferences for Collective Action: A Comparison of a Grassroots Initiative with a Union-Led One
Authors: Zientara Piotr , Adamska-Mieruszewska Joanna
Published: August 2024

Many young individuals now prioritize involvement in collective action as a means to instigate societal change. Crucially, they have access to social media platforms, which help them connect with like-minded peers and coordinate efforts. Some of them may be thus more inclined to favour less conventional collective action over formal union membership. In this study, which draws on data from young British workers during the period from December 2022 to March 2023, we endeavoured to ascertain this cohort’s preferred approach to collective action. We distinguished between an informal grassroots initiative and one led by a labour union as a means to advance the rights of gig economy workers. To this end, we conducted a controlled online experiment. We focused exclusively on a specific age cohort within a particular timeframe, thus limiting our ability to determine generational differences in preferences for collective action and in attitudes toward unions. Nevertheless, the results do offer insights into the forms of collective action preferred by Generation Z. British youth were found to view the informal grassroots initiative more positively than the union-led one. However, they viewed the latter as potentially having greater influence on government policy. Furthermore, they were not significantly more willing to join one initiative than the other. Nonetheless, they were more inclined to recommend the grassroots initiative. This paper contributes to the body of research on the relationship between labour unions and young people. It also provides insight into how members of Generation Z think about various ways of participating in collective action.
Firing modes and predefined-time chaos synchronization of novel memristor-coupled heterogeneous neuron

Published: August 2024

The processing and transmission of biological neural information are realized via firing activities of neurons in different regions of brain. Memristors are regarded as ideal devices for emulating biological synapses because of their nanoscale size, non-volatility and synapse-like plasticity. Hence, investigating firing modes of memristor-coupled heterogeneous neurons is significant. This work focuses on modelling, firing modes and chaos synchronization of a memristor-coupled heterogeneous neuron. First, a novel locally active memristor is proposed, and its frequency characteristics, local activity, and non-volatility are analyzed. Then, the novel locally active memristor is introduced into the two-dimensional HR neuron and the two-dimensional FHN neuron to construct a novel memristor-coupled heterogeneous neuron model. In numerical simulations, by changing the coupling strength, it is found that the model exhibits the periodic spike firing mode, the chaotic spike firing mode, the periodic burst firing mode, and the random burst firing mode. Besides, the dynamic behavior of the novel memristor-coupled heterogeneous neuron can switch between periodic behavior and chaotic behavior by changing the initial state. Finally, based on the Lyapunov stability theory and the predefined-time stability theory, a novel predefined-time synchronization strategy is proposed and used to realize the chaos synchronization of the novel memristor-coupled heterogeneous neuron. The results show that compared with a finite-time synchronization strategy, a fixed-time synchronization strategy and a traditional predefined-time synchronization strategy, the novel predefined-time synchronization strategy has a short actual convergence time. Studying the firing modes and chaotic synchronization of the novel memristor-coupled heterogeneous neuron can help explore the neural functions of the brain and is also important in processing the neural signal and secure communication fields.
Revealing unexpected complex encoding but simple decoding mechanisms in motor cortex via separating behaviorally relevant neural signals
Authors: Li Yangang , Zhu Xinyun , Qi Yu , Wang Yueming
Published: August 2024

In motor cortex, behaviorally relevant neural responses are entangled with irrelevant signals, which complicates the study of encoding and decoding mechanisms. It remains unclear whether behaviorally irrelevant signals could conceal some critical truth. One solution is to accurately separate behaviorally relevant and irrelevant signals at both single-neuron and single-trial levels, but this approach remains elusive due to the unknown ground truth of behaviorally relevant signals. Therefore, we propose a framework to define, extract, and validate behaviorally relevant signals. Analyzing separated signals in three monkeys performing different reaching tasks, we found neural responses previously considered to contain little information actually encode rich behavioral information in complex nonlinear ways. These responses are critical for neuronal redundancy and reveal movement behaviors occupy a higher-dimensional neural space than previously expected. Surprisingly, when incorporating often-ignored neural dimensions, behaviorally relevant signals can be decoded linearly with comparable performance to nonlinear decoding, suggesting linear readout may be performed in motor cortex. Our findings prompt that separating behaviorally relevant signals may help uncover more hidden cortical mechanisms.

Published: August 2024

Os indicadores de performance dos negócios ligados à agricultura familiar são difíceis de se obter devido a utilização de controles informais e falta de padronização de produtos entre diferentes agricultores. Sem a utilização de indicadores o poder público não pode verificar com precisão a eficiência dos recursos públicos empregados na agricultura familiar. Assim, o objetivo desse capítulo é discutir possibilidades a respeito da criação de indicadores de performance econômica e financeira dos agricultores familiares. Os resultados apontam que os agricultores familiares utilizam a percepção da evolução familiar/empresarial, por meio da avaliação patrimonial e de capacidade produtiva, para determinar sua performance. Essa constatação possibilita a elaboração e criação de escalas e instrumentos de coleta que consigam capturar a percepção sobre a avaliação da evolução patrimonial e produtiva dos produtores.

Published: August 2024

O objetivo principal deste trabalho é discutir como a cognição humana, dos atores de mercado, contribui para a plasticidade da constituição do próprio mercado. Para alcançar este objetivo, foi necessário propor duas questões para serem respondidas: (i) como a cognição dos atores do mercado contribui para o mercado tomar forma (se moldar); (ii) como a cognição dos atores do mercado contribui para o mercado assumir e manter sua forma. No intuito de responder estas questões, tomaremos emprestado o conceito de “plasticidade de mercado” de Alderson (1957), bem como o caminho percorrido por Nenonen et al. (2014) como base conceitual que discute como a cognição dos atores do mercado contribui para sua plasticidade. Ao final do trabalho, chegamos que há uma ligação direta, um relacionamento intrínseco entre os modelos mentais cognitivos individuais e as mudanças que ocorrem no mercado. E ainda, que os modelos mentais não se relacionam apenas as mudanças, elas também podem vir a contribuir para a estabilização de um mercado, promovendo uma prática (lógica) dominante.

Place and Duration: The study was conducted at three purposively selected universities in Ogun State, Nigeria. Methodology: A total of 285 lecturers participated in the study, representing a response rate of 92%. Data were collected using questionnaires distributed physically and online. Socio-demographic variables such as age, gender, educational level, type of university, academic rank, and years of service were assessed, alongside coping mechanisms for stress and depression.
Results: Analysis revealed a diverse range of socio-demographic characteristics within the sample. The study found a moderate utilization of adaptive coping mechanisms for stress and depression, while the prevalence of maladaptive coping strategies remained low. Significant correlations emerged between socio-demographic variables such as age, gender, education level, and academic rank, and both adaptive and maladaptive coping strategies for stress. Additionally, age and gender demonstrated significant associations with coping strategies for depression.
Conclusion: These findings underscored the pivotal role of socio-demographic factors in shaping the frequency and nature of coping mechanisms adopted by lecturers. Implications for the design of targeted support interventions within academic environments were discussed.
Recommendations: Universities should prioritize implementing policies and training programs that promote adaptive coping mechanisms for stress and depression among lecturers, fostering a supportive environment that enhances their well-being, resilience, and professional effectiveness.

The target of this study is to use GFTSC (Group for time series modules/components) to classify the constituents components of time series existing in the Ethiopia Gross Domestic Product (GDP). This statistics is the GDP yearly data of Ethiopian Gross Domestic Product (GDP). The Gross fixed capital formation (% of GDP) was available. The (Ethiopia GDP) data for the period of twelve years. The GDP of Ethiopia is a secondary data obtained from the DataStream of National University Singapore Library.  The softness of BFAST (Break for Additive/multiplicative Seasonal and Trend) were inspected by the extension of BFAST to GFTSC. GFTSC was created to involve the cyclical and irregular constituents that was not involved by BFAST technique. GFTSC is aimed to synchronous the image of all the 4 time series constituents. Experiential statistics of Ethiopia was employed to GFTSC and subsequently the next forecast was made. The simulated and real data findings suggested that BFTSC can provide a better time series components identification better than manual process and hence caution should be taken because Ethiopia GDP had only stationery trend, hence not really improving and not dropping, so caution should be taken  less it got to ruin. Improvement in Ethiopia GDP is recommended.

The main objective of this investigation was to boost wheat productivity by reinforce calcareous, sandy and clay soils properties, i.e., some physical and chemical properties of the study soils using organic farmyard manure and Spirulina platensis extract (SPE) for achieving the sustainable agriculture aspect. The field experiments conducted in Kafr El-Sheikh and El-Behera Governorates, Egypt. Yield of wheat crop, concentrations of macronutrient in grains and straw as well as total microbial count were determined. Application of organic farmyard manure (FYM) significantly improved the hydro-physical properties of tested soils, i.e., Bulk density (Mg m-3), Total porosity (%), EC dS.m-1, pH, organic matter, SAR, Cations (Na+, K+, Ca++, and Mg++ meqL-1), Anions (CO3=, HCO3-, Cl- and SO4= meqL-1) and chemical available macronutrient (NPK) compared to control (minerals fertilizer) in the cultivated soils during 2022 and 2023 seasons. Also, Application of Farmyard Manure (FYM), with rate of 10-ton ha-1 and foliar with SPE consisted of 2.4 L during the vegetative growth stages of wheat alone or together improved the yield content of grains and straw of wheat as well as concentrations of N, P, K and protein content during two separated seasons with all soil types under studied. Clay soil had the best effect with the treatments compared with minerals applied where the calcareous soil came in the second-order while the sandy soil came in the last order. Clay soil with the great number of total count. Also, results showed that clay soil was the best effected with FYM application compared with other soils. Thus, on a long- term, these treatments can replace partially N, P and K mineral fertilizers, which reduce production costs and conserve the environment from chemical pollution hazards on human and animal health. Also, will enhance soil propertied and wheat productivity in clay, calcareous and sandy soils.

Ninety six sesame genotypes were evaluated in a Randomized Block Design (RBD) at ICAR- IIOR, Narkhoda farm, to determine the genetic variability, heritability and genetic advance for nine traits. Analysis of variance showed that significant variation was present in the genotypes studied. The phenotypic coefficient of variation was found to be higher than the genotypic coefficient of variation for all the traits. High GCV and PCV levels were recorded for seed yield per plant, number of capsules per plant and plant height. Heritability was high for seed yield per plant, 1000 seed weight, number of seeds per capsule, number of capsules per plant, plant height, days to maturity and oil content. GA (% mean) was high for all the traits except days to 50 % flowering, days to maturity. High heritability coupled with high genetic advance as percent of mean was recorded for seed yield per plant, 1000 seed weight, number of seeds per capsule, number of capsules per plant, plant height and oil content.

Organisms of industrial use are often isolated directly from the environment, most times from the soil, air and water. Amylase producing bacteria and fungi were obtained and isolated from kitchen waste water samples gotten from different hostels and restaurant across Ile-Ife, Osun State, Nigeria. The samples were first screened using pour plate method on nutrient agar and potato dextrose agar, then the isolates were further screened using other differential medium like starch agar.
The isolates recovered were further characterized macroscopically, microscopically and biochemically to ascertain for amylase producing ability. Four bacterial and three fungal isolates were presumptively identified as; Bacillus macerans, Bacillus circulans, Bacillus brevis and Aspergillus niger, Aspergillus flavus , Aspergillus fumigatus.

Pernikahan Atta Halilintar dan Aurel Hermansyah, sepasang selebriti muda, mendulang perhatian yang besar dari masyarakat Indonesia. Rangkaian upacara pernikahan mereka disiarkan baik oleh stasiun televisi nasional maupun kanal- kanal Youtube. Artikel ini menganalisa bagaimana tayangan upacara Siraman Aurel dan tayangan persiapan bulan madu Atta dan Aurel yang dipublikasikan secara terbuka dan luas menjadi upaya penetrasi ideologi meliyankan perempuan dengan menggunakan media sosial. Untuk menjawab pertanyaan tersebut, penulis menggunakan metode studi literatur dan meminjam konsep filosofis Relasionalitas Aku dan Liyan oleh Armada Riyanto. Dalam simpulan terbukti bahwa kedua tayangan tersebut mengandung narasi yang memposisikan suara dan tubuh Aurel sebagai liyan. Penggunaan sosial media menjadi senjata ampuh yang dapat melakukan penetrasi ideologi patriaki tanpa disadari oleh kebanyakan masyarakat Indonesia yang menyaksikan tayangan-tayangan tersebut.

Observing from southern Taiwan on 2 August 2010, a thunderstorm near Luzon Island, Philippines, about 500 km away was found to produce 72 transient luminous events (TLEs). Besides optical images, ULF and VLF sferics of lightning from this thunderstorm were also recorded. This work examines the characteristics of TLE‐producing lightning through studying their ULF and VLF sferics. The attenuation of ULF and VLF sferics in the Earth cavity is obtained through analyzing the sferics associated with Imager of Sprite and Upper Atmospheric Lightning elves that occurred within ~1500 km of Taiwan. Amplitudes of the ULF and the VLF sferics are found to vary as D−0.871 and D−1.207, respectively, where D is the source distance from the sferic stations. After normalizing the sferics from the 2 August 2010 storm to 500 km distance, the ratio of the peak ULF and the VLF magnetic fields is found to be distinct for different TLE‐producing lightning. The ratio for the halo‐producing lightning is nearly 3 times that of the elve‐producing lightning, but it is comparable to that of the halo‐sprite‐producing lightning, although the ULF strength for the halo‐sprite lightning is significantly larger than that for the halo lightning. Therefore, it is possible to distinguish between the TLE‐types using the ULF to VLF peak ratio or the strength of ULF/VLF band emissions of the parent lightning. Comparison of numerically simulated and the observed lightning radiation fields indicates that the best fit discharge time of the elve lightning is about 100 µs, while that for the halo‐producing lightning is between 200 and 500 µs.
