Sustainable Consumption Patterns: Evaluating Consumer Preferences and Barriers in the Adoption of Organic Versus Conventional Agri-Food Products

Abstract This study delves into how consumers view and choose between conventional agri food items focusing on the factors that influence their purchasing decisions amidst growing concerns about climate change and sustainability. By gathering insights from a focus group of 21 individuals, the research uncovers a clear preference for products due to perceived health and environmental advantages. Consumers recognize the quality, taste and nutritional value of items, which justifies their higher price points. Nonetheless challenges like affordability, limited availability and lack of information pose obstacles to adoption. The paper underscores the importance of an approach to promote product consumption through government initiatives awareness efforts, education programs and cost saving production methods.

Vegetation patches modify the acquisition of nitrogen by plants and microorganisms in a degraded alpine steppe

Nitrogen (N) is an essential nutrient for both plants and soil microbes, but it often has limited availability. Currently, little is known about the effects of different vegetation patch types on the partitioning of N between plants and soil microorganisms in grassland ecosystems. In the present study, we performed a 15N-labelling experiment (using 15N-NO3− and 15N-NH4+) to investigate N uptake by plant biomass and microbial biomass for five common vegetation patch types in a degraded alpine steppe on the Tibetan Plateau. The results showed that plants and soil microorganisms in all patches showed a clear preference for the uptake of NO3−. Plants in patches dominated by palatable species absorbed more N than plants in unpalatable species patches, while N uptake in the microbial biomass in unpalatable species patches was higher than that in palatable species patches. For the two soil depths, plants in Poa litwinowiana patches had the highest N uptake (NO3−: 13.32–51.28 mg m-2; NH4+: 0.35–1.36 mg m-2), whereas microbial biomass in Oxytropis glacialis patches had the highest N uptake (NO3−:846.97–1659.87 mg m-2; NH4+: 108.75–185.14 mg m-2) among the five vegetation patch types. For both forms of N, soil microorganisms acquired relatively more N than the plants in the five vegetation patch types (i.e., the ratio of microbial biomass N uptake to plant biomass N uptake was greater than 1). The N-absorbing capacity of plants decreased, whereas the capacity of soil microorganisms to take up N increased with the degradation of vegetation patches. Microorganisms that compete more strongly for N might reduce the uptake of nutrients by plants in degraded patches, which would not be conducive to the restoration of vegetation in N-limited alpine grasslands.

Modern vs traditional indigenous diet preference in Gauteng region, South Africa: A public health concern?

The prevalence of non-communicable diseases still represents a public health concern in South Africa, of which eating habits are some of the main risk factors. A modern diet consisting of the consumption of highly processed foods high in fat, salt and caloric sweeteners and low in fibre is recognised as unhealthy. This study was conducted to assess the penchant of the population for these types of foods rather than traditional indigenous foods known to be healthier. This research was undertaken in the Gauteng region, which is the most urbanized province in the country. This study consisted of a quantitative research survey conducted in 2019 with 1527 participants (Asians, Black, Coloured, Indians and White) aged 18 and above who had lived in the province for at least two years. The results revealed that 30–40 % were neutral on the issue. Despite half (54.4 %) indicating that it was good to mix traditional and modern foods, a clear preference for modern food was noticed for 35.7 % of respondents, with 32.2 % reporting not being concerned that traditional foods have been replaced by modern foods. The traditional indigenous food consumption (TIFC) appeared to depend on monthly total household income, residential area, and settlement category. Participants with specific economic comfort consumed less. Race and number of people in the participants' households also significantly affected the TIFC (p < 0.05). Participants of white ethnicity and those living in a household of a maximum of 02 people displayed the lowest TIFC. In comparison to those who strongly disagree, participants with a neutral opinion about the idea of mixing eating habits were also the most neutral concerning preference for a modern diet (OR: 10.95, 95 % CI 7.00–17.12) and nutrition transition (OR: 14.66, 95 % CI 9.09–23.64). Sensitisation about healthy eating habits among the identified at-risk and target groups is undoubtedly a need in the region to avoid a resurgence of modern diet-related diseases.

Sand Fly larvae are capable of positive chemotaxis: a proof of concept study using Phlebotomus papatasi (Diptera: Psychodidae) as a model species.

Phlebotomine sand flies are important vectors of medical and veterinary importance, transmitting pathogens, such as the Leishmania parasites, responsible for 700,000 to 1 million new cases of leishmaniasis every year. The vast majority of the current sand fly surveillance and control tools are tailored against the adult stages, due to the limited knowledge on the ecology of the larval stages. Since vector control is primarily an ecological problem, an in-depth understanding of the behavior of the target insect pests across all the different life stages of their development is required prior to the development of effective control strategies. It is well known that chemical cues play an important role in insect behavior. While there are numerous studies investigating the behavior of adult sand flies in response to chemical sources, there is currently no information available on the response of their larval stages. In this study, novel bioassays were constructed to investigate the effect of chemical cues (gustatory and olfactory) on the behavior of Phlebotomus papatasi (Scopoli) sand fly larvae. The larvae exhibited a clear food preference within a few hours of exposure in a 2-choice bioassay, while, also, demonstrated positive chemotaxis in response to volatile stimuli emitted from their preferred food source. Identification of the specific chemical compounds (or the combination thereof) eliciting attractance response to sand fly immature stages could lead to the development of innovative, and targeted (larval-specific) tools for the surveillance, and management of these important public health pests.

How HR managers develop ideas about HR reform: the role of inter-corporate knowledge exchange in Japan

Following a call for actor-centric research in HRM, we look at the modes how HR managers acquire HR knowledge. Our interview study with HR managers of large established companies in Japan finds a clear preference for direct inter-corporate knowledge exchanges instead of the engagement of outside consultants. Discussing our findings, we explain the reasons for this preference. ing from the case of Japan, we then propose with reference to institutional theory and isomorphism that the way HR knowledge is spread is linked to the nature of employment systems. In external labour markets, HR knowledge has been reported to be predominantly spread through business consultants, educational institutions, and career changes of HR professionals, resulting in normative isomorphism. We propose that in internal labour markets, like Japan’s, companies resort to direct inter-corporate knowledge exchange, which leads to mimetic isomorphism.

The Combination of Citrus Rootstock and Scion Cultivar Influences Trioza erytreae (Hemiptera: Triozidae) Survival, Preference Choice and Oviposition.

Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae) is a citrus pest which produces gall symptoms on leaves and transmits bacteria associated with the citrus disease Huanglongbing, 'Candidatus Liberibacter' spp. In the present work, the biology and behaviour of T. erytreae were studied in different rootstock-cultivar combinations. Six rootstocks were used, Flying dragon (FD), 'Cleopatra' mandarin (CL), Carrizo citrange (CC), Forner-Alcaide no.5 (FA5), Forner-Alcaide no.517 (FA517) and Citrus macrophylla (CM), and six scion cultivars: 'Star Ruby', 'Clemenules', 'Navelina', 'Valencia Late', 'Fino 49' and 'Ortanique'. Survival and oviposition were evaluated in a no-choice trial, and preference in a choice trial, all of them under greenhouse conditions. Trioza erytreae did not show a clear settle preference for any citrus combination. However, it was able to lay more eggs in 'Fino 49' grafted on CC than on FD. In terms of survival, 'Ortanique' grafted onto FA5 was more suitable than when grafted onto FA517, and in the case of 'Valencia Late', when it was grafted onto CM rather than CC. Our results showed that T. erytreae behave differently depending on the citrus combination.

Turmeric trends: analyzing consumer preferences and willingness to pay

This Research determines the factors influencing American consumers’ willingness to purchase turmeric products, amidst the spice’s rising popularity for its potential health benefits, particularly those linked to its bioactive component, curcumin. Through a comprehensive analysis of a Qualtrics online survey with 1,020 national respondents in the U.S., we employed advanced choice experiment mixed logit models to elucidate consumer preferences regarding product form, origin, sustainability certification, curcumin content, and price. Contrary to the initial hypothesis that curcumin potency would be a primary driver, our results indicate that the place of origin and price significantly shape purchasing decisions, with a clear preference for inland domestically grown, organically certified turmeric products. These insights offer valuable guidance for producers, manufacturers, and marketers in the natural products industry, suggesting a focus on emphasizing local, sustainable sourcing and clear communication of organic credentials to align with consumer expectations. Our findings not only provide a detailed understanding of current consumer attitudes toward turmeric but also highlight potential markets for turmeric–based product development and effective marketing to cater to the evolving demand for health-beneficial natural products.

Adapting to the Digital Age: An Evaluation of Online Learning Strategies in Public Health and Social Care Education

Introduction. The global shift towards digital education in the wake of the COVID-19 pandemic has reshaped the landscape of higher education. Public health and social care programmes have adapted to this transformation, embracing online learning strategies to engage students. This study focuses on the assessment of online learning experiences in public health and social care education, particularly during the post-COVID-19 period. Materials and Methods. This qualitative study employed semi-structured interviews and focus groups with 49 university students in England. These phases, conducted both in person and via video, were audio and video recorded and transcribed verbatim. A purposive sampling technique was employed to gather data, and framework analysis facilitated data management and interpretation. Results. The presentation highlights three main themes and 12 accompanying sub-themes that capture the clear preferences of students for both in-person and online learning methods. The findings elucidate the merits and demerits of online learning strategies in contrast to traditional face-to-face classes. Online classes offer distinct advantages in terms of flexibility, cost-effectiveness, time efficiency, and technological proficiency. However, they also bring to the fore concerns related to social isolation, mental health challenges, technical challenges, and distractions within the home environment. Conclusion. Considering the global transition to digital education, this study contributes to the dynamic discourse surrounding online learning in the post-COVID-19 era. The diverse preferences expressed by students highlight the importance of personalised and flexible teaching methods in online education, underlining the need for adaptability and inclusivity to meet the diverse needs of today’s learners.

Kinetic comparison of all eleven viral polyprotein cleavage site processing events by SARS-CoV-2 main protease using a linked protein FRET platform

The main protease (Mpro) remains an essential therapeutic target for COVID-19 post infection intervention given its critical role in processing the majority of viral proteins encoded by the genome of SARS-CoV-2. Upon viral entry, the +ssRNA genome is translated into two long polyproteins (pp1a or the frameshift-dependent pp1ab) containing all the non-structural proteins (nsps) required by the virus for immune modulation, replication, and ultimately, virion assembly. Included among these nsps is the cysteine protease Mpro (nsp5) which self-excises from the polyprotein, dimerizes, then consecutively cleaves 11 of the 15 cut site junctions found between each nsp within the polyprotein. Many structures of Mpro (often bound to various inhibitor or peptide inhibitors) have been detailed recently, including structures of Mpro bound to each of the polyprotein cleavage sequences, showing that Mpro can accommodate a wide range of targets within its active site. However, to date, kinetic characterization of the interaction of Mpro with each of its native cut site sequences remains incomplete. Here we present a robust and cost-effective FRET based system that benefits from a more consistent presentation of the substrate that is also closer in organization to the native polyprotein environment compared to previously reported FRET systems that employ chemically modified peptides. Using this system, we were able to show that while each site maintains a similar Michaelis constant, the catalytic efficiency of Mpro varies greatly between cut site sequences, suggesting a clear preference for the order of nsp processing.

Specific Grammatical Aspects of Translating the Iaea Regulatory Documents into the Russian Language

The article discusses some grammatical features of the IAEA safety requirements and guides in the English language and in their Russian translations. Considering that these documents make a foundation of the global nuclear safety system, and grammar is the backbone of the language and an essential constituent of the communication content, the paper is focused on the analysis of the ways of translating specific grammatical structures, which determines current importance of this study. The aim of the work is to compare typical grammatical constructions used in the texts of the Russian translations of the IAEA publications under consideration with the grammatical features of similar Rostechnadzor’s regulatory documentation. The main tasks of the authors are to compare the ways of translating English modal and passive constructions, English verbals and verbal structures into Russian and to verify the translator’s choice of a certain grammatical structure in the translations of the regulations and guidelines under consideration. Taking research tasks predetermined the choice of the following research methods: comparative analysis; linguistic and statistical analysis; contextual analysis; inductive and deductive analysis. To obtain linguistic and statistical analysis data, the authors applied such software tools as SDL Trados, Adobe Acrobat, Excel and MS Word. In order to ensure the correctness of the results, only the substantive part of the documents under consideration was analyzed.The analysis has brought to the following results: the need to comply with the regulatory requirements narrows the choice of Russian modal constructions in the translation of "should" statements used in IAEA documents. The issue of changing the regulatory requirement that prescribes to use the Russian verb "следует" has to be treated very carefully, considering the established practice of both translating the IAEA safety guides and their understanding by the target users; the translation of English passive constructions and verbals used in the IAEA safety guides gives clear preference to the use of Russian indefinite-personal structures with verbs in the active voice in the 3rd person plural; the grammatical structures used in the translation of the IAEA publications in question generally correspond to the grammatical structures used in the Rostechnadzor regulatory documents, which is predetermined by the information nature and ensures a fairly high similarity of their style.

Action sequence learning, habits, and automaticity in obsessive-compulsive disorder

This study investigates the goal/habit imbalance theory of compulsion in obsessive-compulsive disorder (OCD), which postulates enhanced habit formation, increased automaticity, and impaired goal/habit arbitration. It directly tests these hypotheses using newly developed behavioral tasks. First, OCD patients and healthy participants were trained daily for a month using a smartphone app to perform chunked action sequences. Despite similar procedural learning and attainment of habitual performance (measured by an objective automaticity criterion) by both groups, OCD patients self-reported higher subjective habitual tendencies via a recently developed questionnaire. Subsequently, in a re-evaluation task assessing choices between established automatic and novel goal-directed actions, both groups were sensitive to re-evaluation based on monetary feedback. However, OCD patients, especially those with higher compulsive symptoms and habitual tendencies, showed a clear preference for trained/habitual sequences when choices were based on physical effort, possibly due to their higher attributed intrinsic value. These patients also used the habit-training app more extensively and reported symptom relief post-study. The tendency to attribute higher intrinsic value to familiar actions may be a potential mechanism leading to compulsions and an important addition to the goal/habit imbalance hypothesis in OCD. We also highlight the potential of smartphone app training as a habit reversal therapeutic tool.

Exploring the impact of windows on musicians’ experience: a neuroarchitecture perspective

ABSTRACT Performing music can be an enjoyable activity or a source of anxiety and discomfort. Previous studies suggest that it is possible to create spaces that promote well-being by applying knowledge from neuroscience to architectural design. However, this application remains unexplored in the context of music practice spaces. In this study, a virtual replica of a real conservatoire classroom was used to investigate the effect of window size and views through windows on the perception of the built environment. A sample of 61 musicians was recruited, and through questionnaires and eye tracking, participants’ responses to environmental changes while playing their instruments were studied. The results of the experiment indicated a clear preference for larger windows, which significantly contributed to a more positive environment, perceived as more open, light, inviting, calming and spacious. In addition, eye tracking data suggested a reduction in anxiety levels, as evidenced by reduced gaze velocity and saccade ratios. These results demonstrate that windows and related variables such as daylight and views can have a significant impact on the experience of musicians during solo performance. This highlights the need to re-evaluate design considerations in music practice spaces, emphasising the crucial role of environmental elements in enhancing musicians’ well-being.

Comparative Analysis of Knowledge Control and Evaluation Methods in Higher Education

The article analyses knowledge control and evaluation methods in higher education, focusing on both standardized and non-standardized testing. It explores fundamental quality criteria and the perspectives of lecturers and students on the roles of these methods in assessing knowledge. The study evaluates attitudes towards both testing types, considering factors such as efficiency, usability, reliability, objectivity, accuracy, and content relevance. The findings suggest that combining standardized and non-standardized tests with problem-solving tasks significantly enhances knowledge assessment in technical disciplines, demonstrating the methods’ interdependence and complementarity. Data shows that both testing types achieve high scores, with standardized tests receiving an integral index of 0.72 and non-standardized tests scoring 0.69. Respondents positively evaluate the effectiveness and convenience of standardized tests, attributing their reliability, objectivity, accuracy, and practical orientation. Although there is a clear preference for standardized tests among participants, the benefits of non-standardized tests are also acknowledged. The study thus recommends a balanced approach, incorporating both methods to ensure an effective and high-quality assessment and knowledge control strategy in higher education.

Bridging cognitive neuroscience and education: Insights from EEG recording during mathematical proof evaluation

BackgroundMuch of modern mathematics education prioritizes symbolic formalism even at the expense of non-symbolic intuition, we contextualize our study in the ongoing debates on the balance between symbolic and non-symbolic reasoning. We explore the dissociation of oscillatory dynamics between algebraic (symbolic) and geometric (non-symbolic) processing in advanced mathematical reasoning during a naturalistic design. MethodEmploying mobile EEG technology, we investigated students' beta and gamma wave patterns over frontal and parietal regions while they engaged with mathematical demonstrations in symbolic and non-symbolic formats within a tutor-student framework. We used extended, naturalistic stimuli to approximate an authentic educational setting. ConclusionOur findings reveal nuanced distinctions in neural processing, particularly in terms of gamma waves and activity in parietal regions. Furthermore, no clear overall format preference emerged from the neuroscientific perspective despite students rating symbolic demonstrations higher for understanding and familiarity.

Bond-selective effect for the dissociative chemisorption of HOD on the Ni(100) surface revealed at the full-dimensional quantum dynamical level.

We present a comprehensive investigation into the dissociative chemisorption of HOD on a rigid Ni(100) surface using an approximate full-dimensional (9D) quantum dynamics approach, which was based on the time-dependent wave-packet calculations on a full-dimensional potential energy surface obtained through neural network fitting to density functional theory energy points. The approximate-9D probabilities were computed by averaging the seven-dimensional (7D) site-specific dissociation probabilities across six impact sites with appropriate relative weights. Our results uncover a distinctive bond-selective effect, demonstrating that the vibrational excitation of a specific bond substantially enhances the cleavage of that excited bond. The product branching ratios are substantially influenced by which bond undergoes excitation, exhibiting a clear preference for the product formed through the cleavage of the excited bond over the alternative product.

Optimizing tourism industry performance strategy selection: an analytical hierarchy process perspective

The tourism industry has an important role in a region's economic growth and development. However, the success of the tourism industry is highly dependent on the strategic policies adopted to increase optimal performance. One way to increase the optimal performance of the tourism industry is to maximize support system facilities. Therefore, this study aims to optimize the performance of the tourism industry by selecting the right strategy based on the support system facilities variable. Support system facilities include telecommunication, power sources, transportation, waste management, location, clean water sources, supporting industries, spatial, hospitality, safety, and security. The Analytical Hierarchy Process (AHP) method selects strategies based on support system facilities. Data is collected through a survey of tourism industry experts and related stakeholders. The results of this study indicate that indicators with high-ranking weights are telecommunication, spatial, and waste management, respectively. Each indicator is calculated for each sub-indicator to find out more in detail about producing the relative priority of the strategy. The analysis shows the importance of each factor in influencing the tourism industry's performance to assist decision-makers in planning and implementing effective strategies. Alternative strategies are prepared based on calculating the weighting of the criteria and sub-criteria. By considering support system facilities as an important factor, strategic decisions can be taken based on clear and measurable preferences.

Treatment planning and delivery practice of lung SBRT: Results of the 2022 ESTRO physics survey

Background and purposeThe use of Stereotactic Body Radiation Therapy (SBRT) in lung cancer is increasing. However, there is no consensus on the most appropriate treatment planning and delivery practice for lung SBRT. To gauge the range of practice, quantify its variability and identify where consensus might be achieved, ESTRO surveyed the medical physics community. Materials and methodsAn online survey was distributed to ESTRO’s physicist membership in 2022, covering experience, dose and fractionation, target delineation, dose calculation and planning practice, imaging protocols, and quality assurance. ResultsTwo-hundred and forty-four unique answers were collected after data cleaning. Most respondents were from Europe the majority of which had more than 5 years’ experience in SBRT. The large majority of respondents deliver lung SBRT with the VMAT technique on C-arm Linear Accelerators (Linacs) employing daily pre-treatment CBCT imaging. A broad spectrum of fractionation schemes were reported, alongside an equally wide range of dose prescription protocols. A clear preference was noted for prescribing to 95% or greater of the PTV. Several issues emerged regarding the dose calculation algorithm: 22% did not state it while 24% neglected to specify the conditions under which the dose was calculated. Contouring was usually performed on Maximum or Average Intensity Projection images while dose was mainly computed on the latter. No clear indications emerged for plan homogeneity, complexity, and conformity assessment. Approximately 40% of the responders participated in inter-centre credentialing of SBRT in the last five years. Substantial differences emerged between high and low experience centres, with the latter employing less accurate algorithms and older equipment. ConclusionThe survey revealed an evident heterogeneity in numerous aspects of the clinical implementation of lung SBRT treatments. International guidelines and codes of practice might promote harmonisation.

Anterior Cruciate Ligament Rupture Combined with Complete Radial Tear of the Posterior Horn of the Lateral Meniscus: Suture or Resection?

Anterior cruciate ligament (ACL) rupture often presents with a tear of the posterior horn of the lateral meniscus. There is no clear preference between ACL reconstruction with suture and resection of the meniscus. We aimed to compare the clinical efficacy of ACL reconstruction with suture versus resection in patients presenting with arthroscopic ACL rupture and radial complete tear of the posterior corner of the lateral meniscus. We retrospectively analyzed 157 patients with ACL rupture and complete radial tear of the posterior horn of the lateral meniscus. Between May 2010 and April 2015, 86 of 157 patients underwent ACL reconstruction and meniscus suture (study group, 54.78%) and 71 of 157 patients underwent ACL reconstruction and meniscus resection (control group, 45.22%) in our department. All patients were monitored over the 12 to 72-month follow-up period. The primary evaluation indices were the Lysholm scores, the International Knee Documentation Committee (IKDC) scores, pivot shift test, the Barret criteria, and magnetic resonance imaging (MRI) findings of meniscal healing. The majority of 157 patients were relatively young men (29.64 ± 7.79 years) with low body mass index (BMI) (23.79 ± 2.74). The postoperative Lysholm and IKDC scores of the two groups were significantly improved over the corresponding preoperative scores (p < 0.05). The clinical results and excellent and good rates were significantly better for the study group than for the control group (both, p < 0.05). MRI showed that the meniscal healed rate of the study group was 96.51%. There was no significant difference in BMI between subgroups for any functional outcome. For patients with ACL rupture and complete radial tear of the posterior horn of the lateral meniscus, ACL reconstruction and both simultaneous suture and resection of the posterior horn of the lateral meniscus were found to be safe and effective. There was no association between outcomes and BMI. However, the former was associated with a superior long-term clinical effect and may restore the integrity of the meniscus and is particularly recommended for young patients.
