On shifting sands: Achieving policy impact in challenging political circumstances.
Authors: Nelson Elizabeth , O'Reilly Dermot
Published: September 2022

The road to policy-engaged research in Northern Ireland has not been smooth. In January 2017 the devolved government at the Stormont Assembly collapsed and devolution was not restored until January 2020. Political turmoil resurfaced in February 2022, with the collapse of the Executive. Trying to engage with and influence policy during these periods has been difficult, but necessary to achieve research impact and demonstrate the utility of data access for research purposes, thus supporting the acquisition of further datasets. This required a paradigm shift in the way research programmes were conceived of and delivered; i.e. away from largely curiosity-based research for academic interest and benefit and towards one that necessitated a more direct engagement and involvement of the government departments and data owners who would benefit from better evidence generated by administrative data research, and incorporate this evidence into their policymaking and service provision.
Aligning the academic and policy agenda increased the likelihood of successful data acquisition, the prerequisite for research success and subsequent research impact. It also creates a more stable environment for data research to flourish, even in challenging political circumstances.
This presentation will detail the approach developed by researchers and engagement professionals in Northern Ireland during political and governmental collapse to embed and enhance the potential impact that data research can have on policy by supporting the design and development of research that answers the questions most relevant to policymakers whilst also maintaining academic independence and integrity. It will offer suggestions for engaging and involving political representatives and policymakers, and for creating a resilient, robust and sustainable approach to policy impact that can withstand shifting political sands, based on recognised best practice of embedded engagement built to develop and maintain trust.

Published: September 2022

ObjectivesUK longitudinal population studies have complex governance structures and participant safeguards. As a new Trusted Research Environment (TRE) for >20 longitudinal studies, the UK Longitudinal Linkage Collaboration (UK LLC) must ensure effective public/participant input to make central design and operational decisions whilst retaining participant trust and acceptability.
ApproachThe UK LLC’s governance model is based on the principle that participant trust lies with their study; not supporting infrastructure providers. Therefore, the UK LLC takes responsibility for system governance and data sharing agreements whilst studies retain control over participant data and its uses. Our public/participant model reflects this. We have established centralised groups to advise on data access applications and on UK LLC communications. Simultaneously we work with study managers to gain insight from their involvement work and also commission UK LLC specific activities. Including participants as well as the public helps elicit a range of input and views.
ResultsWe have integrated public/participant input across the UK LLC by recruiting: a public panel to review applications; an advisory panel to contribute to our methodological development; and public/participant advisors to sit on the UK LLC Strategic Advisory Committee. We also work with studies’ involvement managers to draw insights from, and coordinate new, study-level involvement.
This has informed the development of data application frameworks and brings a public viewpoint to decisions regarding linkage of functionally anonymous participant NHS records for research. The involvement of study participant groups has shaped the design of data flows into the TRE (e.g., where some studies do not permit the flow of address data for geospatial research) and has helped set a ‘social contract’ regarding acceptable UK LLC data use.
ConclusionWorking with public/participant representatives directly, and in partnership with study managers, we have developed safeguards and integrated a public/participant voice into key UK LLC activities. Our ongoing aim is to develop a sustainable new-way-of-working for record linkage in longitudinal research which is acceptable to participants and the public.
A cross-sectional analysis on the effects of biodiversity and green space on mental well-being in Wales.
Authors: Thwaites Oliver
Published: September 2022

ObjectiveA growing body of evidence suggests that biodiversity and greenspaces are positively associated with mental well-being. However, studies have been undertaken over small spatial scales and population-scale evidence is lacking. This study aimed to investigate associations between parks, biodiversity and mental well-being for individuals living in Wales in 2018/2019.
ApproachThis cross-sectional study linked GIS derived data, socio-demographic and survey datasets to analyse how mental well-being varied with biodiversity per greenspace for individuals living in Wales for each Lower Super Output Area (LSOA). Mental well-being was defined using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). All records of bird, butterfly and plant species in 2018 were downloaded from the National Biodiversity Network Atlas Wales. Greenspace measures were acquired from Ordnance Survey. Associations between greenspace, biodiversity and mental well-being were investigated using Generalised Additive Models to allow for non-linear relationships.
ResultsThe size of the cohort was 10,441, the average age was 55 (s.d. 18.6), 55.2% were female and 94.4% were White British. This study found that greenspace area (m2), the total number of species, number of bird and number of plant species (all per m2 greenspace) had positive statistically significant relationships with mental well-being. After adjustment for socio-demographic factors, the number of plant species (per m2 greenspace) remained a significant predictor of mental well-being, with a positive linear relationship. There was no statistically significant relationship between the number of butterfly species per m2 greenspace and mental well-being in unadjusted or adjusted models. Furthermore, socio-demographic factors explained most of the variation in mental well-being.
ConclusionThis study adds further evidence to the benefits of biodiverse environments on mental well-being through nature connectedness. Specifically, people living in an LSOA with more plant species per m2 greenspace report better mental well-being. Environmental interventions should consider increasing plant species richness which may benefit mental well-being.
UK Longitudinal Linkage Collaboration – and the challenges in creating a new Longitudinal Populations Studies linked data resource.

Published: September 2022

ObjectivesThe UK Longitudinal Linkage Collaboration (UK LLC) is a new, unprecedented infrastructure enabling research into the COVID-19 pandemic. The UK LLC integrates data from >20 UK longitudinal studies with systematically linked health, administrative and environmental records to facilitate cross-disciplinary COVID-19 research for accredited UK based researchers.
ApproachBringing together all of the key components that form the UK LLC was a huge challenge that may have only been possible in the midst of the pandemic. First, we collaborated with the Longitudinal Population Studies (LPS) to create and agree how data linkage, data provision and applications to access the UK LLC would work. In parallel, public contributors helped to create fair processing materials. Finally, we worked closely with NHS Digital and other key national data providers to organise approvals for all studies to be linked, and for the UK LLC to have delegated decision-making for research applications.
ResultsWe faced a myriad of challenges creating the UK LLC including:

Short timeframe and short-term funding structure – initial funding for six months with an 18-month extension.
Working across >20 different LPS and four nations with different structures for access, consent and data provision.
Lack of capacity at various points in the data pipeline due to the volume of COVID-19 research required and underway across the involved organisations.
Data processing complexities – split data method means no one can see the entire process therefore catching linkage errors requires working across four different organisations.
With such complex data flows it is challenging to find the balance with communications about data to the public – being accurate about what we are doing, but expressing the complexity in lay terms.

ConclusionCreating the UK LLC required collaboration with LPS, data providers and researchers. An iterative approach to creating the data application and data provision pipelines was crucial in developing these processes. The UK LLC was built quickly, from initial funding in October 2020 to provisioning data to researchers in December 2021.
Analisis Pemakaian Kombinasi Fly Ash Tipe F Dan Slag 1:1 Pada Beton Geopolymer Dengan Na2SiO3 Dan NaOH Sebagai Alkali Aktivator: Sebuah Kajian Literatur
Authors: Solikin Mochamad
Published: September 2022

Upaya yang dapat diterapkan oleh para ahli untuk mengurangi gas CO2 dan pemanasan global yang disebabkan dari proses produksi semen adalah pengembangan pembuatan beton yang ramah lingkungan salah satunya beton geopolymer. Beton geopolymer dibuat dengan material utamanya mengandung silika tinggi dan alumina antara lain fly ash tipe F dan slag, yang dicampur dengan alkali aktivator berupa Na2SiO3 dan NaOH. Dikarenakan slag lebih mahal maka beberapa peneliti mencampurkan fly ash tipe F agar biaya pembuatan beton lebih murah. Studi literatur ini bertujuan untuk menganalisis kuat tekan beton geopolymer kombinasi slag dan fly ash tipe F 1:1, metode curing terhadap kuat tekan, dan biaya pembuatan beton geopolymer. Metode studi literatur ini dengan cara mengumpulkan data sekunder dari jurnal yang sudah dipublikasikan. Hasil pembahasan kuat tekan beton geopolymer dengan kombinasi fly ash dan slag 1:1 kuat tekan tertinggi pada molaritas 16M sebesar 65,17 MPa dan terendah 8M sebesar 51,7 MPa. Dengan metode curing oven selama 24 jam dapat meningkatkan kuat tekan karena proses polimerisasi dan polikondensasi dapat berlangsung secara optimal. Perbedaan harga antara beton geopolymer kombinasi fly ash dan slag 1:1 dengan beton normal sebesar 40% lebih mahal hal ini disebabkan penggunaan alkali aktivator sebagai bahan pengikat pada beton geopolymer yang masih mahal di pasaran Indonesia.
Perbandingan Antara Metode USLE dan MUSLE Dalam Analisis Erosi Lahan Pada Daerah Tangkapan Air Waduk Cengklik
Authors: Abdurrosyid Jaji , Saputra Krisna Dwi Aji
Published: September 2022

Waduk Cengklik adalah waduk yang terletak di Desa Ngargorejo, Kecamatan Ngemplak, Kabupaten Boyolali, Provinsi Jawa Tengah. Waduk Cengklik sendiri memiliki fungsi utama sebagai pemasok air irigasi pada 3 kecamatan yaitu Sambi, Ngemplak, dan Nogosari. Oleh karena setiap tahunnya waduk cengklik mengalami penurunan tampungan air menyebabkan kurangnya pasokan air ke pertanian di 3 kecamatan terutama saat musim kemarau. Hal ini disebabkan oleh besarnya laju sedimentasi yang terjadi. Penelitian ini bertujuan untuk menghitung laju sedimentasinya yang nantinya bisa dilakukan penangan agar sedimentasi di waduk bisa berkurang dan tampungan air pada waduk tidak berkurang. Prediksi erosi dan laju sedimentasi pada penelitian ini menggunakan 2 metode yaitu USLE (Universal Soil Loss Equation)  dan MUSLE (Modified Universal Soil Loss Equation). Dari hasil penelitian ini diperoleh nilai faktor erosifitas hujan (R) dari tahun 2010-2019, faktor erodibilitas tanah (K) sebesar 0,23, faktor panjang dan kemiringan lereng (LS) sebesar 0,4, faktor tanaman penutup lahan dan faktor tindakan konservasi (CP) sebesar 0,491 sehingga didapatkan besar erosi dan laju sedimentasi menggunakan Metode USLE sebesar 66,698 ton/ha/tahun dan 14,653 ton/ha/tahun. Lalu diperoleh nilai debit banjir maksimum (QP), volume aliran permukaan (VQ) dan limpasan permukaan (R) tahun 2010-2019 sehingga erosi dan laju sedimentasi menggunakan Metode MUSLE sebesar 35,106 ton/ha/tahun dan 7,713 ton/ha/tahun. Kemudian didapatkan rasio pembadingan antara Metode USLE dan MUSLE sebesar 1,90 : 1,00.

An Empirical Research on Schema Theory Based Teaching of the Continuation Task for Chinese Senior High School Students
Authors: Wang Qing , Chen Liping
Published: September 2022

The continuation task, a novel type of source-based writing task which requires students to read and accomplish an unfinished source text, has gained growing popularity in English writing tests, particularly in China. This study employed schema theory in the teaching of senior high school continuation tasks and delved into its resultant effects on learners’ overall writing ability, lexical richness, syntactic complexity, and semantic coherence. Theoretically, it serves as an extension of the Schema theory, Practically, it contributes to the improvement of the continuation task instruction and offers a realistic method to achieving better writing from the perspectives of linguistic schema, content schema, and formal schema. This research revolves around such questions: What effects do schema theory-based Continuation task instructions have on students’ overall writing competence; lexical richness; syntactic complexity and semantic coherence? During the research, two groups of EFL students (N=110) from Chinese senior high schools participated in the trial for fourteen weeks. One group was randomly selected as Control Class where the teacher adopted traditional teaching approaches. At the same time, the other was set up as the Experimental Class guided by schema theory. The participants writing performance were evaluated through the lexical richness, syntactic complexity and semantic coherence. Sample T-test and paired T-test found statistically significant differences between the Control class and the Experimental class. These findings suggest that the schema theory-based approach, such as providing a semantic map or outlining the story to participants, was proven effective in honing the students’ overall writing capability, lexical richness, syntactic complexity, and semantic coherence. Because of the chosen research approach, its efficacy is limited concerning language and discourse.
Conflict in Atwood’s The Handmaid’s Tale: A Critical Discourse Approach
Authors: Razzaq Naji Ola , Fadhil Abbas Nawal
Published: September 2022

Conflict is a common but complicated phenomenon. It has been extensively researched in many domains, including philosophy, sociology, psychology, and linguistics. Using the Critical Discourse Approach, this study examines the issue of self-society conflict in The Handmaid’s Tale. The significance of this work lies in the identification and explanation of the discursive strategies that force the ideological polarization of the positively portrayed self versus the negatively portrayed other. The purpose of this study is to answer two questions: what are the discursive strategies used in The Handmaid’s Tale to create a positive or negative representation, and how are these strategies implemented? Five extracts from The Handmaid’s Tale were examined using eight of Van Dijk’s discursive strategies (2006). The findings show the pervasiveness of the discursive strategies in The Handmaid’s Tale, which attempt to transmit the ideological polarization of a positive portrayal of the self against a negative presentation of the other. Students of critical discourse analysis, communications studies, and of English, in particular, may find the findings useful.

Published: September 2022

Direct Metal Laser Sintering (DMLS) is an additive manufacturing technology gaining popularity due to its ability to produce near net-shaped functional components. As there is a great need to improve the surface quality of DMLS components to upgrade their dynamic properties, an attempt was made to study the influence of process parameters like laser power, scan speed, and overlap rate on the surface quality of DMLS Aluminum alloy (AlSi10Mg) in as-built condition. The optimized process window to generate the best surface quality was achieved using Response Surface Method (RSM). Artificial Neural Network (ANN) modeling is also developed to map the influence of process parameters on surface quality. Conclusively, Scan speed is found to be most influential over surface quality as per the F and P test results. The optimized process parameters for best surface quality (3.52 µm) were 300 W laser power, 600 mm/sec scan speed, and 25% overlap rate. Both RSM and ANN models were accurate in prediction. However, ANN is recorded as superior with the highest coefficient of correlation (R).

Published: September 2022

The lubrication system of an aero-engine is intended to lubricate and cool bearings, gears, and splines to ensure a high level of safety and reliability for many operating hours of an aircraft. One of the important accessories of the lubrication system of an aero-engine is the oil pump which consists of multiple pumps with tandem gerotor elements housed in a single casing. The lubrication pump consists of multi positive displacement pumps of “GEROTOR” type, driven by a single shaft. The aim of this paper is to study the influence of altitude conditions on the pump performance and develops a simulation technique for the prediction of output flow rate at various on and off-design conditions. A numerical study has been conducted using commercial CFD code ANSYS-Fluent. Volumetric efficiency is considered as the main parameter for the evaluation of pump performance at various operating conditions. Further, the experimental study has been carried out by simulating low inlet pressure conditions at the inlet of the pump. The comparison between simulation and experimental results shows that results are matching within a 6% deviation. Thus, the simulation method is appropriate for predicting the altitude performance of gerotor pump used in the lubrication system of an aero engine. The study concludes that the contribution of inlet pressure to the pump performance is significant.

Flooding is one of the problems experienced by many countries no matter what their economic status is. Even rich and developed countries experience it too. Flooding is mainly caused by natural events such as typhoons and monsoon rains even anthropogenic causes that sometimes could not be stopped even if there are flood control structures in place. The Philippines is located in the Pacific Ring of Fire and is visited by an average of 20 typhoons each year. People are used to experiencing flooding and it is about time that we somehow do something about it. There have been many technologies available right now that could aid us to improve our capability to adapt to such phenomena. Heavy precipitation is usually experienced during the monsoon season that leads to severe flooding in a specific area. The application of HEC-RAS (Hydrologic Engineering Centre’s River Analysis System) Modelling Software was used in the study in Manghinao River for comprehensive hazard mapping and risk assessment in the downstream area of the Bauan River for 100-year return period flood. 2D flood hazard simulation was done and the river water level that would trigger flooding downstream was identified. At 0.5 m of flood height, people are considered immobilized to move from one place to another so the best time to evacuate people is before the flood reaches that level. Results showed that LGU has 4 hours to evacuate people starting when the river water at the gaging station reads 0.5 m, this gives them enough time to give warning and ask people to move to evacuations sites to prevent them being stranded in their houses. This study can support future planning and for the development of flood control plans and flood mitigation measures to minimize the losses due to flood disasters in Batangas Province, Philippines particularly in the Bauan area.

Published: September 2022

One of the important airline services that can influence the passengers’ loyalty is the in-flight meal service. In this study, the conceptual design process of new in-flight food delivery and waste collection system is carried out using the standard engineering design method to improve the current system. A critical step in this process is the design concept evaluation and selection where the best alternative design concept solution is chosen for further development. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method is applied to facilitate the selection process of the best design concept for the new improved in-flight food delivery and waste collection system. The design evaluation criteria for the TOPSIS assessment procedures are taken from previous work done on design requirements analysis for the new in-flight food delivery and waste collection system. Similarly, five alternative design concepts for the new system are taken from the results of the previous research work done. Furthermore, an online public survey is conducted to acquire the assessment rating of all alternative design concepts for each design evaluation criterion. The assessment rating is assigned using a simple Likert rating scale. From the resultant TOPSIS ranking, Concept 3 has emerged as the best design concept with a closeness rating of 0.9589, which is very close to 1. For future research work, this selected final design concept for the new in-flight food delivery and waste collection system will be forwarded to the next engineering design stage for further development.
Computational Mechanics Analysis in Elevated Shell Platform Structures

Published: September 2022

Shell structures are usually used in roof applications and aerospace structures. The advantage of these structures is not fully utilized in transmitting applied force. A thin-shell structure can be used for building construction and aerospace structures due to its lightweight nature. The township high load in this study refers to the high-speed airflow in the case of aerospace. This study was conducted to justify the feasibility of applying a thin-shell structure as an elevated shell platform for township foundations, where several different geometries were analyzed using finite element analysis (FEA) and artificial neural network (ANN). In the findings, all maximum stresses from different geometries are lower than the design value, thus verifying the feasibility of constructing a shell platform for heavy loading applications. The regression plots from the ANN output show that all geometries approached the value of 1, which means that the predicted ANN output and actual datasets of FEA are almost similar. From the ANN predicted output, the mean square error (MSE) was calculated. All the MSE values obtained from each geometry approached zero, indicating the analysis is precise and has a minimal error. Thus, this study has justified the feasibility of proposing elevated shells for township applications, which can be used as a reference in the design phase for future implementation.

Published: September 2022

The mini channel is used widely in industrial applications. The application includes a heat exchanger device, as a part of a cooling system or as a reactant transport channel. However, unlike the pressure drop determination of a piping network, where the loss coefficient values for the bends and fittings are available, similar cannot be done for the mini channel. The loss coefficient values for the channel are rarely determined and reported. The aim of this study is to propose a correlation for the prediction of total pressure drop in a mini channel resulting from the loss coefficient. The results were compared against a numerical simulation. A 42 mm x 50 mm pin type mini channel was used as the sample of the study. The fluid was hydrogen. The flow regime was kept as laminar. The numerical simulation was performed on the whole active area. The correlation was calculated using the loss coefficient values of bends that were determined beforehand. Three correlations were proposed. Statistical values were used as the comparison parameters. Based on the results, an almost similar pressure drop was predicted by correlation III (diff. mean ± SD = 0.005 ± 0.006 kPa). The correlation I and correlation II were not able to predict the expected results at all. The results were from a low Reynolds (range of Re < 200) number. In general, the correlation proposed successfully predicted the pressure drop in a pin-type mini channel using the loss coefficient value of the individual bends.

Este es un número especial dedicado a la Escuela de Salamanca, o mejor dicho (y como queda probado con las contribuciones parte de este ejemplar), la Escuela Española de Economía moral (EEE). Resulta que, debido a la leyenda negra (hispanófoba, Roca, 2016. Sánchez-Bayón, 2012 y 2013), máxime en sus últimas ediciones (la anti-franquista y regionalista española, más la indigenista y descolonial latinoamericana), se ha renunciado y borrado cualquier herencia española, especialmente si fue tan brillante como la de EEE. Esta escuela fue un referente del pensamiento moderno, guía de la globalización de entonces y presente en todo el mundo conocido (al menos en su red de universidades, Sánchez-Bayón, 2010 y 2015): favoreció el tránsito de la teología tradicional o pura (sobre los atributos de Dios), a la moderna o política (sobre la organización política del pueblo de Dios); del iusromanismo al nuevo derecho de gentes y/o Derecho Internacional; del iushumanismo natural al positivo (vía el derecho común estatutario de Indias), etc.

Nossa proposta é investigar como essas mortezinhas se manifestam em produções literárias contemporâneas lusófonas e, para isso, elegemos três obras: A gorda, de Isabela Figueiredo, Esse cabelo, de Djaimilia Pereira de Almeida e A vida invisível de Eurídice Gusmão, de Martha Batalha.
Literatura e violência: entrevista com Tatiana Salem Levy
Authors: Silva Sandro Adriano da
Published: September 2022

O cenário da literatura brasileira contemporânea de autoria feminina e, por extensão, os estudos críticos, especialmente de vertente feminista que têm nela seu escopo, apontam para a emergência de visibilidade e legitimação das singularidades das autoras, suas demandas temáticas e suas assinaturas estéticas, mormente nucleadas por complexos processos de interseccionalidade de gênero, classe, e relações étnico-raciais. Nesse sentido, Figueiredo (2020), ao mapear a produção em prosa feminina brasileira do século XXI, constata que as escritoras

têm demonstrado cada vez maior liberdade na escrita ficcional de aspectos que envolvem seus corpos, abordando temas como erotismo, gravidez, aborto, maternidade, estupro, incesto, relações abusivas, menstruação, TPM, distúrbios alimentares (anorexia e bulimia), automutilação, prostituição, lesbianidade, velhice (Figueiredo, 2020, p.11).

A violência de gênero, tanto física quanto simbólica, que tem apresentado índices alarmantes, é legitimada ao se inscrever “em uma natureza biológica que é, por sua vez, ela própria uma construção naturalizada” (Bourdieu, 2015, p.33) e apresenta uma faceta objetiva, segundo Žižek (2015, p. 18), posto estar sustentada em uma “normalidade do nível zero contra a qual percebemos algo como subjetivamente violento”. Vista Chinesa, último romance de Tatiana Salem Levy, emerge como exemplo de “formas essenciais de vulnerabilidade que inscrevem o corpo da mulher num quadro de relações assimétricas com consequências muitas vezes dramáticas” (Besse, 2018, p. 37) – levadas à experiência-limite do estupro e no trauma que constitui narrá-lo. Nesta entrevista, a autora discorre sobre essas e outras questões que incidem sobre seu fazer literário, sua condição de gênero e as reverberações necessárias no debate público.
‘Sou um animal muito antigo, também serei mulher bomba’ ou a história segundo Tatiana Pequeno
Authors: Martinez Luciana Teixeira
Published: September 2022

A partir da aproximação entre a forma como Hélène Cixous concebe a escrita feminina em O riso da Medusa e a crítica ao progresso e à História de Walter Benjamin, este artigo lê três poemas da poeta brasileira Tatiana Pequeno. São eles “museu nacional”, “museu nacional.2” e “querida,”, todos retirados do livro Onde estão as bombas (2019). A hipótese é a de que se pensarmos, como Cixous, que a escrita da mulher articula uma temporalidade singular que tanto provoca rupturas na história homogeneizante quanto promove encontros potencialmente transformadores entre a história pessoal e coletiva, poderemos olhar para textos escritos por mulheres como reescritas de uma nova história, singular e múltipla, que – com Benjamin – é possível chamar de revolucionárias. Este trabalho identifica na poesia de Tatiana Pequeno os ecos desta pequena revolução, destas rupturas na História.

The experiment was set up in a split-plot configuration with three replications. The examined factors were: I – morphotypes of winter oilseed rape: population (Poznaniak), hybrid restored with a semi-dwarf type of growth (PX104), hybrid restored with a traditional type of growth (Konkret); II – four types of biostimulators: 1. control variant,  2. biostimulator Tytanit® (titan), 3. biostimulator Asahi®SL (sodium ortho-nitrophenol, sodium para-nitrophenol, sodium 5-nitroguaiacol), 4. biostimulator Silvit® (active silicon, potassium oxide, boron – form of pure element, zinc – form of pure element). The aim of the study was to evaluate the effect of biostimulators containing various active substances on the morphological characteristics of winter oilseed rape plants in the leaf rosette stage (number of rosette leaves, tap root length, height of the growth cone) and on the fresh and dry mass of the above-ground rosette and the root system of traditional and semi-dwarf winter oilseed rape morphotypes type of growth under changing climatic conditions. The genetic factor significantly influenced the morphological features of plants, marked in autumn by inhibition of vegetation. The population variety Poznaniak developed more rosette leaves, greater length of the tap root, and fresh and dry mass of the rosette and the root system as compared to the restored hybrids. The applied biostimulators significantly influenced plant parameters determined in the fall before the vegetation inhibition. After the use of a biostimulator containing the active substance in the form of sodium o-nitrophenol, sodium para-nitrophenol and sodium 5-nitroguajakol, a significantly higher value of the tested features was obtained compared to the control variant. Regardless of the type of biostimulator used, the height of the growth cone was the same as in the control object. The most favourable parameters of the leaf rosette were obtained in the first and second periods of summer-autumn vegetation and winter dormancy, while in extreme drought conditions during sowing and a fairy dry period of emergence, its weakest features were obtained. Natural growth stimulants are becoming an increasingly common elements of agricultural plant agrotechnics. Their use has a positive effect on the growth and development of plants and increases the resistance of plants to the adverse effects of stress factors.
From Incubation to Sustainability: a Case-Study of Graduated Companies in Portugal
Authors: Almeida Cunha Alegre Silva Maria Teresa , Clara Ribeiro Parente Cristina
Published: September 2022

The purpose of this article is to discuss business incubators as a new way to boost companies and create jobs in a very competitive economic context.  From a sociological perspective inspired by concepts such as those of “network” and “social capital”, we analyse the entrepreneurial ecosystem as an instrument to overcome challenges during post-incubation. A qualitative research based on a multiple case-study in companies formerly incubated at the Science and Technology Park of the University of Porto (UPTEC) was conducted to analyse the impact of incubation on graduation and growth. The research objective was to understand the importance of business incubators for business sustainability. Our findings show that companies from the UPTEC were strengthened during incubation, particularly as a result of available low cost services and the reproduction of their networking context through the implementation of business communities after incubation.

Published: September 2022

Objective: the aim of this study is to analyze how and how often the fire protection approach is included in the curriculum of engineering courses.
 
Theoretical reference: fire protection has gained the spotlight, in large part, as a result of some disasters that have occurred in recent years. The subject has evolved and gained considerable prominence, thus requiring changes in current legislation, as well as the formulation of new Standards and Laws, capable of mitigating the risk of fire occurrence. It is necessary to understand the role of the future engineer on the fire protection policy, to avoid possible fire occurrences in institutions. So, several studies from literature about fire have been used to a theorical basis of this research.
 
Methodology: a systematic literature review whit Prism protocol have been used to a review literature. The databases used and selected for this study was Google Academic, Scielo and Eric was carried out in a quantitative analysis. Secondly, in a qualitative analysis, a case study was carried out, starting with an investigation of the curriculum of nine engineering courses at a Brazilian university, to verify the consistency of the fire protection approach and compliance with the “Kiss Law” in the courses studied.
 
Results and conclusion: the results indicate a certain insufficiency of disciplines when analyzing the curricular matrices of each course. In most cases, the adoption of contents or disciplines that address the topic present fire protection generically and inconsistently. It is concluded that there is still a lack of knowledge about the relevance of the topic and effective non-compliance with legislation on the subject. There is, therefore, a need for implementation measures in the learning topics of engineering curricula.
 
Originality/ value: There are few studies on fire protection in the school environment.  So, the originality of this study is in analyzing how engineering schools are implementing fire protection legislation and how this practice is effective for collective safety.
"The Perspective of Waste Pickers on Their Work: Incentives and Challenges in a City in a Developing Country"
Authors: De Oliveira Suellen Araújo , Ribeiro Ana Regina Bezerra , Sobral Marcos Felipe Falcão
Published: September 2022

Objective: The present research aimed to identify, from the perspective of the collectors of recyclable materials, the challenges and incentives of performing their work in a city of a developing country.
 
Introduction: Waste generation is expected to grow significantly by 2050 in developing countries, making them the largest generators of MSW in the world. The Circular Economy is reflected as an alternative for dealing with the waste issue, since it seeks to promote the reduction of waste generation. For developing countries, the collectors of recyclable materials are important players in reinserting the materials into the production cycle. Brazil is an important player in this scenario, since it ranks among the five largest SUW generators in the world and has waste pickers as the majority responsible for waste recycling in the country.
 
Methodology: Semi-structured interviews were conducted with 67 of the 125 organized waste pickers recognized by the city government, whose answers were categorized and analyzed qualitatively with quantitative contribution coming from the correlation in three stages: incentives, challenges, and incentives and challenges.
 
Results and Conclusion: The study concluded that, for the Brazilian city collectors, the main stimulus for carrying out their professional activities is income generation, followed by collaboration to cause a positive impact on the environment. And, as the main challenge, the non-separation followed by the inadequate disposal of waste, which compromises the quality of the materials and the collectors' health.
Determining Factors For Social and Environmental Practices of Corporate Responsibility in Mozambique
Authors: Madime Eulália , Gonçalves Tiago Cruz
Published: September 2022

Purpose: This study analyzes the main factors that determine the adoption of social and environmental practices in companies operating in Mozambique. To this end, it analyzes the perception of managers about the pressure, motivation and barriers they face for these practices.
 
Theoretical framework: Corporate Social Responsibility (CSR) is based on legitimacy, stakeholder and institutional theories. The stakeholder theory has two variants: one that concerns the attention to all stakeholders in the activities of the organization; the second is understood in a strictly organization-centered manner and relates to empirical responsibility. The latter coincides with the concept of legitimacy theory where they try to ensure that their activities are perceived as being legitimate. In institutional theory, the dependence of an organization creates isomorphisms of structure, climate and behavioral focus.
 
Method/design/approach: The data were collected through a stratified sampling survey according to the size and nature of the activities, using Likert type questions. Constructs of Pressure, Internal Motivation and Barriers to CSR practices were assessed, as well as compliance with social and environmental practices. A number of 227 representative responses of Mozambican business fabric were obtained. To analyze the data and test the conceptual model presented, we used the PLS (Partial Least Squares) methodology.
 
Results and conclusion:. The results show that there is little pressure from stakeholders and society in general, low motivation of the agents responsible for practicing social and environmental actions and that they recognize that barriers exist, but do not have a significant effect on the decision to adopt CSR practices. It was also found that in the CSR analysis, social practices should be seen separately from environmental practices.
 
Research implications: The study argues that managers consider the multi-factors involved in CSR. It also points to important contributions to the definition of economic policies and institutional designs, particularly in developing countries, to leverage CSR practices.
 
Originality/value: This study contributes to the literature by demonstrating that, although there are positive conditions, negative factors (barriers) in the determination of social and environmental practices should not be neglected. Additionally, the conclusions presented differ significantly from the results obtained in geographies of developed countries, thus contributing to the understanding of the determining factors in African countries, which has been less studied, and in particular in Mozambique, to which we contribute in a pioneering way.
