This research is motivated by the inability of internal audits to encourage the performance of strategic government programs implemented in Islamic State Universities (PTKN). One of the government's priority programs run by PTKN is the program to strengthen religious moderation. This study aims to identify internal control models implemented in tertiary institutions. These supervisory models are then examined for their empowerment potential to encourage the performance of strengthening religious moderation. For this purpose, the researcher empowered the case study qualitative research method by collecting data using observation, interview, and documentation techniques. The data collected was checked for validity using the triangulation technique and analyzed using the Miles, Huberman, and Saldana technique. The results of the research show that: (1) 2 models of internal control have been implemented in tertiary institutions, namely: the partial-thematic internal audit model and the collaborative internal control model; (2) identified 1 (one) audit model that has the potential to be studied further and that in the future it can be applied to tertiary institutions, namely the integrative audit model; (3) models of internal control that tertiary institutions have implemented can be empowered to support and encourage the strengthening of religious moderation and other strategic program.

Currently there has been an increase in demand for bottled water, this is due to the population’s dissatisfaction with the quality of water provided by public agencies. The present study sought to evaluate the presence of biofilm-forming P. aeruginosa in bottled drinking water. Thirty-five typical bottled water samples were selected to identify the presence of P. aeruginosa and its ability to form bacterial biofilm. The methodology used to verify the presence of P. aeruginosa followed the multiple tube technique and the evaluation of biofilm forming capacity followed the microdilution technique, with the optical capacity read by spectrophotometry at 620 nm. The presence of P. aeruginosa was detected in 26% of the samples analyzed, representing nine of the 35 samples tested. Of these, 55% had the ability to form biofilm. The present study shows that the presence of P. aeruginosa, which is capable of forming biofilms, is a risk factor for public health because of the widespread commercialisation of bottled water.

Synthesis and Properties of Hypercoordinate Stannanes and Polystannanes
Authors: D’Amaral Gloria
Published: September 2023

Asymmetric tetraorganotin (IV) compounds containing either a flexible propyl alcohol ligand (10) or a semi-flexible ethyl 2-pyridyl ligand (11) were synthesized in good yields via select hydrostannylation reactions. The triphenyl derivatives were converted in good yields to their dihalide stannane intermediates (6, 7), respectively, by mild sequential chlorination with HCl or by reaction with Br2. The dihalides were converted to reactive dihydride monomers (8, 9) by a reaction with LiAlH4 or NaBH4 in good yields. All stannane intermediates and monomers were fully characterized by NMR (1H, 13C, 119Sn) spectroscopy and high-resolution mass spectrometry. DFT calculations were also performed on the ethyl 2-pyridyl stannane intermediates 2 and 7, which revealed optimized structure geometry and electronic energies. From the three methods that were used, M05-2X-GD3 showed the lowest mean sum of squared distances (MSSD) value and the lowest electronic energies of the hypercoordinate structures. Polymerization of the corresponding dihydrides in the presence of both early and late transition metal catalysts produced moderate molecular weight polymers 10a and 11a. Compound 10a was cast onto a transparent film for the first time and was additionally coated on a PET film. While the cast film on PET showed good flexibility, an initial evaluation of its electronic properties using a 4-probe conductivity device revealed no intrinsic semi-conductivity. Optimization of the polymerization of 10a involved a catalyst screening, using alternative dehydrocoupling catalysts. A new ethyl 2- pyridyl containing polystannane 11a was synthesized with a Mw of 11,200 Da using RhCl(PPh3)3, and 119Sn NMR revealed the presence of both 4- and 5-coordinate Sn centers randomly distributed along the backbone. 
Using a GIS Approach to Evaluate Spatial Accessibility to Neighbourhood Amenities and Natural Environmental Features: Implications for Older Adult Health in the Toronto CMA
Authors: Wehr Alexandra
Published: September 2023

Older adults (i.e., adults aged 65+) have become the fastest-growing age group in Canada. This demographic shift has resulted in accelerated demand for health-promoting resources as older adults age in place. This project analyzes potential spatial accessibility of health-promoting neighbourhood amenities (NAs) and natural environmental features (NEFs) among Census tracts and Census subdivisions in the Toronto Census Metropolitan Area. Spatial accessibility of these resources is analyzed for older adults residing in different neighbourhoods and communities. Geographic information systems are used to implement methods including the enhanced two-step floating catchment area accessibility model, location quotient, and bivariate local indicators of spatial association. Two travel scenarios (i.e., walking and driving) represent common modes of transportation. Results indicate significant variation in spatial accessibility between NAs and NEFs and spatial mismatch between older adult concentration and spatial accessibility. This project provides a modest basis for improvement of service provision, supportive infrastructure, and health promotion. 
An Investigation of Social Media Use for Environmental Norm Development: An Exploration of an Emerging Multi-Actor Regulatory Governance Normative Process
Authors: Martin Madeleine
Published: September 2023

This dissertation posits that social media platforms (e.g., Twitter and Facebook) represent a new process and fora for the development and implementation of norms that regulate environmental behaviour, with unique characteristics, strengths, and weaknesses, when compared with conventional processes and fora for regulatory activity and codified norm development, such as state-based legislative assemblies and non-state standards bodies. Distinctive features of social media platforms affect user interactions and experiences, which in turn impact how environmental norm conversations take place on those platforms, as opposed to norm conversations that take place through legislatures or formal standards processes. In addition, distinctive characteristics of public sector, private sector, and civil society actors affect how they use social media in development of environmental norms. This research hypothesizes that the way in which social media is used to formulate environmental norms and the importance of social media as a venue for environmental norm conversations varies, depending in large part on distinctive characteristics of the governance actors (i.e., government, third sector actors, and the private sector) and their societal roles, interacting with the distinctive characteristics of social media. In addition to a cross-disciplinary review of scholarly literature, this dissertation explores the veracity of this hypothesis using two investigations; one that compares the use of Twitter by two Ontario government agencies, and a second case study that explores of a Twitter micronorm conversation about the groundwater operations of the water bottling industry in Ontario and other jurisdictions. 
Landscape and Hydrologic Patterns' Impact on Microbial Activity: A Comparison of Arctic Watersheds
Authors: Bushnell Ross
Published: September 2023

Water security is a significant issue facing communities of the Canadian Arctic and is a fundamental component to the health, economic development, and ecological integrity of northern communities. Local water sources are under pressure from environmental changes and anthropogenic influences and need to be understood in order to protect them. The aim of this study was to collect landscape, hydrologic, and microbial baseline data in the communities of Baker Lake, Nunavut and Pond Inlet, Nunavut watersheds in order to, (1) characterize each of the study watersheds, (2) explore the relationships between precipitation, vegetation distributions, water chemistry, and microbiological indicator total coliforms (TC), (3) guide future research and source water management, (4) create capacity for northern communities to conduct watershed research. These research goals were guided by the residents of the study communities and volunteers collaborated to achieve this research in all part of the research process. Measurements were taken at two watersheds in Baker Lake, Nunavut during the summer of 2019 and six watersheds in Pond Inlet, Nunavut in the summers of 2017 and 2018. Watersheds that had higher proportions of Wet vegetation generally had higher TC measurements during the sampling season. In addition, the results showed that major precipitation correlated with higher TC measurements, though a 3-5 day lag between the precipitation event and the TC increase was found. The lag time between the spike in TC and the rain event varied temporally and spatially. The results suggest that watershed vegetation composition, slope, and hydrologic patterns influence the lag time between the “flushing” of the landscape and the response of microbiological indicators. The results will contribute to baseline knowledge which policy makers and the community can use to establish policies to ensure the health and sustainability of northern water sources. In addition, placing a emphasis on the exchange of knowledge with northern residents will facilitate the capacity for the communities to conduct their own research in the future. This local scale research is vital for northern communities to be able to prepare for the impacts climate change and development is having on their environment. 
The Continuation of Native Non-Invasive Plant Species Research of Engineered Wetlands
Authors: Tucci Joanna
Published: September 2023

Wetlands are vital ecosystems that are capable of polishing wastewater. Although there is extensive research on constructed wetland wastewater treatment, information regarding the use of native non-invasive macrophytes is lacking. The first part of this study examined the use of native non-invasive plant species in laboratory-based engineered wetlands to assess their growth and nutrient removal. The blue flag iris, cardinal flower and sneezeweed were chosen for the experiment as they developed best under the laboratory conditions. Plant biomass increased with phosphorus additions and phosphorus concentrations remained high and were not reduced. The results are preliminary and further research is necessary. 

In the second part of this thesis the Palgrave Forest and Wildlife Area was visited to assess species identification, presence and seasonality. A total of 15 plant species were identified at the wetland, where 5 are invasive. As expected, seasonality had an impact on wetland productivity, biomass and species presence. 
Analysis of Variables Affecting Customer Satisfaction Using Online Food Purchase Services with Multiple Linear Regression
Authors: Wilujeng Fuji Rahayu
Published: September 2023

The surge in popularity of online food delivery services across Southeast Asia is undeniable. Remarkably, in the year 2020, Indonesia emerged as the frontrunner in Gross Merchandise Value (GMV) for such services in the region, amassing an impressive GMV of $3.7 billion, surpassing its regional counterparts. This burgeoning trend is underpinned by a multitude of factors motivating individuals to embrace online food purchases, including time efficiency, an array of enticing and pragmatic offers, and an abundance of choices. Building upon this backdrop, this research endeavors to delve into the intricate web of variables that wield influence over consumer satisfaction within the realm of online food procurement. Employing the multifaceted approach of multiple linear regression, the study aims to uncover the mechanisms that underlie this pivotal relationship. The findings gleaned from this investigation are noteworthy. They highlight the substantial joint impact of the independent variables on the dependent variable. This assertion is substantiated by the remarkably minute significance value of F, which registers at an impressive 0.000, comfortably falling below the conventional threshold of 0.05. This statistical affirmation underscores the collective potency of the five dimensions of service quality, cohesively exerting a significant influence on the variable of customer satisfaction. Moreover, a granular examination of the individual impacts of each independent variable warrants’ attention, as gleaned from their respective 't' significance values. It is discernible that the variables of reliability and responsiveness, with significant values exceeding 0.005, exhibit limited individual impact on customer satisfaction. This discernment underscores that, when assessed in isolation, these two independent variables fail to manifest a statistically noteworthy effect on the overarching construct of customer contentment.

Published: September 2023

Pistacia terebinthus L. ili smrdljika je listopadni grm ili nisko stablo iz porodice Anacardiaceae. Autohtona je vrsta Mediterana, a u Hrvatskoj je široko rasprostranjena od Istre, preko Hrvatskog primorja, Dalmacije, Dalmatinske zagore do krajnjeg juga. Kserofitna je vrsta, koja raste na osunčanim položajima u makijama i šikarama eumediteranske i submediteranske zone na suhim, toplim, kamenitim i stjenovitim mjestima. Na području prirodne rasprostranjenosti tradicionalno se koristila u prehrani, kao i u liječenju mnogih zdravstvenih tegoba, kao što su respiratorne i urinarne infekcije, želučane tegobe, reumatizam, itd. U novije vrijeme, analize kemijskog sastava vrste upućuju na znatan sadržaj mnogobrojnih aktivnih sastojaka visoke nutritivne vrijednosti i ljekovitog djelovanja (npr. eterična ulja, proteini, tanini, nezasićene masne kiseline, flavonoidi), a najpoznatija je po sadržaju smole iz koje se izdvaja terpentin. Zbog veće otpornosti na sušu, temperaturne ekstreme, bolesti i štetnike te s obzirom na rasprostranjenost na našem području, smrdljika ima najveći potencijal kao podloga za cijepljenje prave tršlje ili pistacije (P. vera L.), cijenjene zbog svojih plodova, što danas predstavlja upotrebu od najvećeg gospodarskog značaja, a prvi nasadi već se podižu u srednjoj Dalmaciji. Najčešći način cijepljenja je okuliranje koje se provodi na dobro razvijenim dvogodišnjim podlogama smrdljike. Izvjesni problem koji se javlja kod proizvodnje podloga je niska klijavost sjemena smrdljike zbog fiziološke i fizikalne dormantnosti, partenokarpije i abortiranja sjemenki. Dostupna znanstvena i stručna literatura kao i rezultati preliminarnih terenskih istraživanja upućuju na postojanje velikog potencijala upotrebe smrdljike u agronomiji, šumarstvu, farmaciji i prehrambenoj industriji.

THE IMPORTANCE OF ENVIRONMENTAL EDUCATION AT AN EARLY AGE
Authors: Lamanauskas Vincentas
Published: September 2023

There is no doubt that environmental education at an early age is significant for human development. When we refer to an early age, we mean the preschool and the primary stage of education (preschool education institution and primary school). It is obvious that the foundations of personality are formed at this stage, primarily a positive attitude towards nature and the surrounding world. At this stage, the child begins to distinguish himself from the environment, an emotional and value attitude towards the environment, nature, himself, and other people, etc., is formed. On the other hand, knowledge corresponding to a certain age of a personality (e.g., ecological), norms and rules of interaction with nature are required, on the other hand, it is extremely important to develop empathy for nature through various activities (e.g., actively solving certain environmental problems). It can be reasonably stated that the formation of values, nature cognition and a sustainable lifestyle are three essential factors determining (describing) the importance of environmental education. Thus, environmental education at an early age not only helps to develop environmental awareness but also promotes abilities and the attitude, which can determine a sustainable and responsible lifestyle in the future. From this point of view, the continuity and sustainability of this education is extremely significant. Environmental education in primary school can have a long-term effect on children’s moral and worldview behaviour and contribute to sustainable development and global well-being. The period of primary education is a suitable and favourable environment for the formation of children’s positive and rational attitude towards the environment, promoting environmental awareness and developing a sustainable lifestyle.

THE RELEVANCE OF LEARNING OUTCOMES INCLUDED IN ESTONIAN GRADE 7-9 SCIENCE SUBJECT CURRICULA ASSOCIATED WITH THE CONCEPT OF ENERGY
Authors: Kõlamets Lauri , Kasuk Heili , Holbrook Jack , Mamlok-Naaman Rachel
Published: September 2023

This study on the Estonian lower secondary (7-9th grade) science curricula, is seen as an important framework for educators preparing students as tomorrow’s citizens able to reflect on sustainable energy development. As the curriculum is taken to be the major document allowing insights into Estonian educational standards, this study identifies components within the intended lower secondary science curricula for subjects of biology, chemistry, earth science, physics, and interdisciplinary science. Using document analysis, verbs associated with career-related learning outcomes are detected, allowing the relatedness of the energy conceptualizations and determination of their cognitive level utilizing SOLO (Structure of Observed Learning Outcomes) taxonomy. A team of coders identify a total of 782 learning outcomes across three learning domains: psychomotor (176), affective (32), cognitive (574) at unistructural (33), multistructural (225), relational (276), and extended abstract (40) levels. The majority of energy concept learning outcomes (274) are identified in the source (form) and transfer (transform) categories. Very few career-related learning outcomes are detected with the science education relevance dimensions (individual, societal, career). The suitability of the findings is discussed. The current analyzing method can be applied to other educational disciplines for raising awareness of disciplinary crosscutting concepts.

BLENDED LEARNING ON WECHAT PLATFORM-BASED SPOC IN LOWER-SECONDARY SCHOOL SCIENCE TEACHING
Authors: Xu Tugen , Xu Jiaying , Xu Xiaoqing , Lu Jijian
Published: September 2023

This paper proposes a blended teaching design model on WeChat Platform-based SPOC and carries out an empirical study of its applicability and effectiveness in lower-secondary school science teaching. Participants were from two eighth grade classes with different academic performance, and after conducting the same blended teaching, it was found that pre-class knowledge transmission on the WeChat platform considerably enhanced students’ classroom participation, which was also highly related to their improved post-class test scores. The improvement in the performance of the weak groups is more obvious. In addition, backend data from the WeChat platform revealed that the number of resource clicks was significantly higher than the total number of students, indicating that the sharing function of the WeChat platform facilitated the sharing of educational resources. Seven in-service science teachers were also interviewed to qualitatively evaluate and analyze the teaching model from the perspective of in-service teachers. The comprehensive results indicate that the teaching model constructed in this study achieves good results, facilitates the development of students’ independent learning ability, and allows for the integration of this blended teaching model into lower-secondary curriculum.

Management Practices and Success of Innovation Projects
Authors: Mignenan Victor
Published: September 2023

Innovation projects occupy a privileged place in human activities: they are carriers of socio-economic values and levers of strategic positioning. This article improves understanding of the success of innovation projects in Chad through project management practices (PMP) and benefits management practices (BMP). To achieve this, the literature has made it possible to propose a model for representing success. The mixed methodology was used. It was applied to the Grand Ecosystem Lacustres Tchadiens (GELT) project. The results show that PMPs are more effective in achieving innovation management success (β = 0.38) but also investment success (β = 0.21). On the other hand, BMPs are better predictors (β = 0.39) of investment success. However, PMPs and BMPs, when combined, are the preferred lever to generate (Δr2= 92%) the success of innovation projects.
Examining the Entrepreneurial Mindset and Entrepreneurial Intentions
Authors: Cater, III John James , Young Marilyn , Hua Lei
Published: September 2023

We examined factors contributing to developing entrepreneurial intentions (EI) and the relationship between EI and the entrepreneurial mindset (EM) among nascent student entrepreneurs. Further, we seek to increase awareness among business practitioners of the value of nascent entrepreneurs to the economy. Utilizing the theory of reasoned action and the theory of planned behavior, we investigated personal and contextual factors related to EI. We surveyed 400 US business college students, comparing those with EI (n=228) and those without EI (n=178). Our findings indicated that compared to respondents who did not have EI, respondents who possessed EI reported several significant personal factors. Specifically, they were more likely to view themselves as entrepreneurs, have family members who owned their own businesses, lead group projects as students, and have previously worked in a startup business. Additionally, the contextual factor of the Covid-19 pandemic positively affected business students who possessed EI.

This study seeks to underscore the extent to which macroeconomic vectors cause foreign direct investment inflows using cointegration, vector error correction, impulse response functions, and variance decomposition techniques against annual Nigerian data from 1986 through 2020. It also attempts to unravel how FDI inflows respond to macroeconomic shocks. The results indicate that, in the long-run, interest rate, inflation, exchange rate, level of economic activity and growth, and degree of trade openness of the economy significantly cause FDI inflows to Nigeria. Whereas the direction of causation is positive for inflation, exchange rate and trade openness of the economy, it was negative for level of economic activity and interest rate. FDI inflows responded to shocks in the above independent variables in different directions, some positively for a designated time, while some negatively at other periods. Generally, shocks in the independent variables jointly affected the shocks in FDI from the second through the tenth periods of innovations. Policy implications favor government action to lower interest rate, maintain mild inflation and moderate devaluation of the Naira against the currencies of trading partners, among others.

The demand for specialty coffees on the world market is growing, and their commercial value is directly linked to their quality. When subjected to ultraviolet (UV) light, some raw coffee beans show a blue fluorescence. Around the world, producers and traders have used UV light as a quality analysis method to detect defects in beans that cannot be seen with the naked eye. Despite being a technique used for a long time, almost no scientific study has been done to confirm and clarify the matter. Therefore, the work aims to evaluate the quality of the beans that emit and do not emit fluorescence from the same batch. For this, a batch of natural specialty coffee was divided into treatments with different fluorescence concentrations and analyzed sensorially and physicochemically. It was observed that the increase in fully fluorescent beans concentration negatively affected the coffee final score and astringency, and the increase in partially fluorescent beans concentration negatively affected the final score, astringency, sweetness, acidity, bitterness, and aftertaste of the coffee. Furthermore, attributes such as fruity notes and sweetness were affected by the presence of fluorescence, thus changing the sensory profile. In the physicochemical analyses, a reduction in the coffee quality was observed for the parameters of potassium leaching, electrical conductivity, fatty acidity, polyphenols, titratable acidity, moisture and weight of 1000 seeds. Therefore, it was possible to observe that the use of UV light to assess the green coffee beans quality can be a viable method.

Introdução: O Suporte Básico de Vida (SBV) é um conjunto de procedimentos de emergência que tem como objetivo manter as funções respiratórias e cardíacas de uma pessoa que sofreu uma parada cardiorrespiratória (PCR) até que a ajuda médica especializada chegue. Essas técnicas incluem a realização de manobras de reanimação cardiopulmonar (RCP), que envolvem a aplicação de compressões torácicas, ventilações, desobstrução das vias aéreas, administração de oxigênio e desfibrilação. Objetivo: Este estudo tem como objetivo principal realizar uma revisão integrativa do nível de conhecimento do leigo ao profissional de saúde acerca do suporte básico de vida. Metodologia: Revisão bibliográfica descritiva em caráter exploratório de abordagem qualitativa, a partir de publicações científicas encontradas nas bases de dados da PUBMED, SCIELO e Google Acadêmico. Resultados: O estudo contou com a amostra de 9 artigos, dos quais o nível de conhecimento do suporte básico de vida foi citado em todos os artigos. Discussão: Revelou uma situação preocupante, com grande parte das pessoas se sentindo incapazes de agir em emergências. Conclusão: É imprescindível que haja capacitação da população em geral sobre o suporte básico de vida, assegurando desta forma uma menor taxa de morbimortalidade.

Deming Cycle method, which is a standard method that contains a continuous improvement model developed by W. Edward Deming. This method consists of four main components arranged sequentially, namely the PDSA (Plan-Do-Study-Action) cycle.  The workflow of the production department will be fast and efficient, while the Quality Control will be in a position to ensure that all work is completed to the exact specifications and terms according to the standards suggested in the project. The data collection method used to obtain data in writing this final project uses several data collection techniques of Observation, Interview and Documentation. The research model uses the Deming Cycle or PDCA Cycles. To re-check whether the corrective action is working as intended or not with FMEA analysis (Failure Mode and Effect Analysis). FMEA analysis is carried out with FMEA spreadsheet. The Deming Cycle Method is a methodology that will be used as a method to ensure that Total Quality Management will be able to reduce defects and repetitive work during production process for modular building construction in the oil and gas sector. This PDCA found that Quality Issues are the main factor of  failures or delays which will impact to the cost.

Peanut (Arachis hypogaea L.) growers use different tillage systems in the Southeastern United States, the impact of which needs to be assessed with regard to evapotranspiration (ET), carbon uptake, and water-use efficiency (WUE). The eddy-covariance method was used to measure these fluxes in peanut in two common tillage systems (strip tillage vs. conventional tillage) over the course of three consecutive growing seasons (2019–2021). Results suggest that during the dry year of 2019 with rainfall of only 30 cm, strip tillage peanut had a significantly higher daytime ecosystem WUE, 105%, 51%, and 32% higher than that of the conventional tillage in early, mid, and late growth stages, respectively. In 2020, with mean rainfall the overall difference in average WUE was nonsignificant between the tillage systems. Heavy rainfall of 112 cm in 2021 led to waterlogged conditions in the conventional tillage field due to poorer infiltration. This likely reduced the CO2 uptake. Waterlogging did not occur in the strip tillage field due to improved infiltration. As a result, in 2021, 18%, 33%, and 48% greater ecosystem WUE in strip tillage during early, mid, and later stages was found. Thus, this study suggests that strip tillage fields can achieve higher net CO2 uptake and WUE in Georgia during dry or very wet years. However, no difference in WUE was found between different tillage systems in a typical year with average rainfall for Georgia. The present study has implications for regions characterized by long growing seasons and low rainfall.
