Background: Academic integrity is presented as a complex, multidimensional concept that involves all members of an educational institution. However, non-teaching staff members are often excluded from research on academic integrity. I engaged in professional support alongside academic staff to explore how academic integrity is understood within the Mauritius branch of a UK higher education institution.

Methods: I adopted a qualitative approach to engage those tasked with implementing academic integrity to examine how they understood and practised it. Data were gathered through face-to-face focus-group interviews, which were translated into themes.

Results: This article identified the factors that make academic integrity challenging and presents recommendations for practitioners and researchers.

Conclusions: More energy should be invested in the processes that build cultures of integrity rather than focusing on the opposite, such as cheating, plagiarism, and misconduct. Academic integrity is ultimately a positive values-driven approach to learning and a skill that can be developed and strengthened.

背景:学术诚信是一个复杂的、多维度的概念,涉及教育机构的所有成员。然而,非教学人员经常被排除在学术诚信研究之外。我与学术人员一起从事专业支持工作,探索如何在英国高等教育机构毛里求斯分校理解学术诚信。方法:我采用了一种定性的方法,让那些负责实施学术诚信的人来检查他们是如何理解和实践学术诚信的。通过面对面的焦点小组访谈收集数据,并将其转化为主题。结果:本文确定了使学术诚信具有挑战性的因素,并为从业者和研究人员提出了建议。结论:应该把更多的精力投入到建立诚信文化的过程中,而不是专注于相反的方面,比如作弊、抄袭和不当行为。学术诚信最终是一种积极的价值观驱动的学习方法,是一种可以发展和加强的技能。

Background: A pressing challenge in science education is that visually impaired students continue to lack access to appropriate instructional media, making it difficult for them to engage with abstract concepts and resulting in limited opportunities for equitable education. Responding to this challenge, the present study investigates the design and implementation of hands-on, multisensory instructional strategies aimed at improving conceptual understanding of magnetism among elementary students with visual impairments.

Method: The research involved four elementary school students with varying degrees of visual acuity. Employing the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) framework, the research was divided into 3 stages: needs analysis (A) using explanatory case study, design and develop (DD) instructional media and validate using Aiken's V, implement and evaluate (IE) the media into classroom activity using evaluative case study.

Result: The findings indicate that tactile models, auditory explanations, and adapted activity kits significantly improved students' engagement and comprehension of key magnetism concepts such as magnetic properties, forces, and polarity. Through an evaluative case study, the research demonstrates that instructional materials tailored to the sensory and cognitive profiles of visually impaired learners not only foster deeper conceptual understanding but also promote greater participation and confidence in science learning.

Conclusions: Multisensory science kits help students access abstract science material so that it can be felt and helps achieve conceptual understanding. Moreover, the results may inform teachers, curriculum designers, and science education professionals on how to design and adapt science content in ways that are both accessible and pedagogically sound.

背景:科学教育面临的一个紧迫挑战是,视障学生仍然缺乏适当的教学媒体,这使得他们难以接触抽象概念,从而导致公平教育的机会有限。为了应对这一挑战,本研究调查了动手、多感官教学策略的设计和实施,旨在提高视觉障碍小学生对磁性的概念理解。方法:以四名不同视敏度的小学生为研究对象。采用ADDIE(分析、设计、开发、实施和评估)框架,研究分为3个阶段:需求分析(A)使用解释性案例研究,设计和开发(DD)教学媒体并使用艾肯的V进行验证,使用评估性案例研究实施和评估(IE)媒体进入课堂活动。结果:触觉模型、听觉解释和适应性活动包显著提高了学生对磁性、力和极性等关键磁性概念的参与和理解。通过一项评估性案例研究,研究表明,针对视障学习者的感官和认知特征量身定制的教学材料不仅能加深对概念的理解,还能提高他们对科学学习的参与度和信心。结论:多感官科学工具包帮助学生接触抽象的科学材料,使其能够感受到,并有助于实现概念理解。此外,研究结果可以为教师、课程设计者和科学教育专业人员提供信息,告诉他们如何以既易于理解又适合教学的方式设计和调整科学内容。

Background: This study aimed to document the occurrence of the Egyptian fruit bat Rousettus aegyptiacus in King Salman Bin Abdulaziz Royal Nature Reserve (KSRNR), Hail region, Saudi Arabia, where its presence had not previously been confirmed.

Methods: Field surveys were conducted in the Hail region, and direct observations were documented using photographic and video evidence. The colony was visually counted in the field during a single daytime visit from an estimated distance of 15 meters.

Results: More than 50 individuals, including adults and juveniles, were observed roosting in a rock crevice. The photographic documentation confirms the presence of a colony of R. aegyptiacus in this area, extending the known distribution of the species into a previously unrecorded region of Saudi Arabia.

Conclusions: These findings provide the first photographic record of R. aegyptiacus in KSRNR and highlight the species' ecological use of arid rock crevices. The results emphasize the need for targeted surveys and long-term monitoring to better understand the distribution and conservation of this species in desert environments.

Influencer Marketing in Rural Tourism: Enhancing Destination Image and Encouraging Homestay Choices. 乡村旅游中的网红营销:提升目的地形象,鼓励民宿选择。
Q2 Pharmacology, Toxicology and Pharmaceutics Pub Date : 2026-01-08 eCollection Date: 2026-01-01 DOI: 10.12688/f1000research.173947.1

Rural tourism remains underexplored compared to urban and luxury destinations, yet it offers significant potential for sustainable development. Travel influencers, through digital storytelling and endorsements, are increasingly shaping tourist perceptions and reducing uncertainties about homestays. This study examines the impact of influencer endorsements on homestay intentions, utilizing the Theory of Planned Behavior as a guiding framework. Data from 216 urban tourists in Northern and Central India were analyzed with structural equation modeling. Findings reveal that rural image perception is the strongest predictor of homestay intentions, while subjective norms play a weaker but significant role. Influencer endorsements affect behaviour indirectly by enhancing destination image rather than exerting direct persuasion. The study advances the Theory of Planned Behavior by demonstrating the primacy of cognitive evaluations over normative pressures in the context of rural tourism. Practical implications underscore the need for destination marketers and homestay operators to utilize authentic storytelling and image-building strategies to effectively promote rural tourism.

与城市和豪华旅游目的地相比,乡村旅游仍未得到充分开发,但它提供了可持续发展的巨大潜力。通过数字叙事和代言,旅游业的影响者正在越来越多地塑造游客的观念,并减少关于寄宿家庭的不确定性。本研究利用计划行为理论作为指导框架,探讨网红背书对寄宿家庭意向的影响。本文采用结构方程模型对印度北部和中部216名城市游客的数据进行了分析。研究发现,乡村意象感知对民宿意愿的预测作用最强,主观规范对民宿意愿的预测作用较弱但显著。网红代言通过提升目的地形象间接影响行为,而不是施加直接说服。该研究通过证明在乡村旅游的背景下,认知评价比规范压力更重要,从而推进了计划行为理论。实际意义强调目的地营销人员和民宿经营者需要利用真实的故事和形象塑造策略来有效地促进乡村旅游。

A bibliometric review of research on resilience, motivation and prisoners, 1912-2024. 1912-2024年对心理弹性、动机和囚犯研究的文献计量学回顾。
Q2 Pharmacology, Toxicology and Pharmaceutics Pub Date : 2026-01-06 eCollection Date: 2025-01-01 DOI: 10.12688/f1000research.164019.3

Background: Research on resilience and motivation among incarcerated populations has expanded substantially over the past century, reflecting a broader shift in penal philosophy from punitive control toward rehabilitation and reintegration. However, this literature remains fragmented across disciplines, conceptually heterogeneous, and geographically uneven, with a strong concentration in Western contexts. This limits theoretical integration and constrains the global applicability of existing models.

Methods: A bibliometric analysis was conducted on 1,309 publications indexed between 1912 and 2024. Co-occurrence, citation, collaboration, and temporal overlay analyses were performed using VOSviewer to map thematic structures, intellectual influences, and patterns of knowledge production. Inclusion criteria targeted peer-reviewed and scholarly works addressing resilience and/or motivation in correctional settings.

Results and discussion: The analysis reveals a temporal shift from early psychological adjustment and behavioral control models toward integrated frameworks emphasizing resilience, motivation, rehabilitation, and post-release reintegration. Emerging themes include trauma-informed care, addiction recovery, human rights, and reentry processes, while gender-specific, cross-cultural, and socioeconomic reintegration perspectives remain underdeveloped. Citation and collaboration networks demonstrate strong institutional concentration in North America and Western Europe, reflecting structural and epistemic asymmetries that shape dominant theoretical paradigms. Although interdisciplinary integration has increased, comparative and culturally grounded research remain limited.

Conclusions: This review synthesizes a century of research into a coherent intellectual map, identifying key trends, gaps, and structural imbalances in the field. The findings highlight the need for more inclusive, culturally responsive, and structurally informed research frameworks that integrate psychological, institutional, and social dimensions of rehabilitation. Advancing this agenda is essential for developing correctional policies and interventions that are both empirically robust and globally relevant.

背景:在过去的一个世纪里,对被监禁人群的恢复力和动机的研究已经大大扩展,反映了刑罚哲学从惩罚性控制向改造和重新融入社会的更广泛转变。然而,这些文献仍然是跨学科的碎片化,概念上的异质性,地理上的不均匀性,并强烈集中在西方背景下。这限制了理论的整合,限制了现有模型的全球适用性。方法:对1912 ~ 2024年间1309篇文献进行计量分析。使用VOSviewer进行共现、引用、协作和时间叠加分析,以绘制主题结构、智力影响和知识生产模式。纳入标准针对的是同行评审和学术作品,涉及惩教环境中的恢复力和/或动机。结果和讨论:分析揭示了从早期心理调整和行为控制模型到强调弹性、动机、康复和释放后重返社会的综合框架的时间转变。新出现的主题包括创伤知情护理、成瘾康复、人权和重返社会过程,而针对性别、跨文化和社会经济重新融入的观点仍然不发达。引文和合作网络在北美和西欧显示出强大的机构集中度,反映了形成主导理论范式的结构和认知不对称。虽然跨学科的整合有所增加,但比较和文化基础的研究仍然有限。结论:这篇综述将一个世纪的研究综合成一个连贯的知识图谱,确定了该领域的主要趋势、差距和结构失衡。研究结果强调,需要建立更具包容性、文化响应性和结构知情的研究框架,将康复的心理、制度和社会层面结合起来。推进这一议程对于制定既具有经验有效性又具有全球相关性的惩教政策和干预措施至关重要。

Background: The cannabinoid 1 (CB1) receptor is the primary target of Δ 9-tetrahydrocannabinol (Δ 9-THC), the psychoactive component of cannabis sativa (commonly known as "kif" in Morocco).

Methods: Here, we identified novel CB1 agonists using virtual screening approaches. First, we developed a pharmacophore model based on the known CB1 agonist AM11542 and screened a database of over three million compounds. Molecular docking using AutoDock Vina identified 61 hits with binding affinities of less than -9.00 Kcal/mol. Subsequent ADME-Tox (absorption, distribution, metabolism, excretion, and toxicity) analysis narrowed the selection to 18 promising candidates.

Results: Among these, three agonists exhibited strong characteristics, including a favorable inhibition constant (Ki) and key hydrogen-bond interactions with critical residues in the CB1 binding pocket: PUBChem157251136 (Ki=2.09 nM), ZINC64438485 (Ki= 0.262 nM) and ZINC64438506 (Ki =0.244 nM). These agonists formed stable hydrogen bonds with CB1 binding pocket residues (Ser383, Ser173, His178 and Thr197). Molecular dynamics simulations (100 ns, GROMACS) demonstrated structural stability (RMSD < 1 nm) and low conformational flexibility (RMSF < 1 nm) for all complexes. MM-GBSA binding free energy calculations further confirmed the thermodynamic stability of all complexes, with interaction energies ranging from -30.59 to -49.98 kcal/mol. These comprehensive simulations confirm that all identified agonist complexes maintain stable binding conformations with optimal interaction profiles characteristic of CB1 receptor activation.

Conclusion: These results could pave the way for researching and developing new quinazolinz-2, 4(1H, 3H)-Dione derivatives as a new class of CB1 receptor agonists.

背景:大麻素1 (CB1)受体是Δ 9-四氢大麻酚(Δ 9-THC)的主要靶点,大麻是大麻的精神活性成分(在摩洛哥通常被称为“kif”)。方法:在这里,我们使用虚拟筛选方法确定了新的CB1激动剂。首先,我们基于已知的CB1激动剂AM11542建立了药效团模型,并筛选了超过300万种化合物的数据库。利用AutoDock Vina进行分子对接,鉴定出61个结合亲和力小于-9.00 Kcal/mol的位点。随后的ADME-Tox(吸收、分布、代谢、排泄和毒性)分析将选择范围缩小到18个有希望的候选药物。结果:其中3种激动剂表现出较强的特征,包括良好的抑制常数(Ki)和与CB1结合口袋中关键残基的关键氢键相互作用:PUBChem157251136 (Ki=2.09 nM), ZINC64438485 (Ki= 0.262 nM)和ZINC64438506 (Ki= 0.244 nM)。这些激动剂与CB1结合的口袋残基(Ser383, Ser173, His178和Thr197)形成稳定的氢键。分子动力学模拟(100 ns, GROMACS)表明,所有配合物的结构稳定性(RMSD < 1 nm)和低构象柔韧性(RMSF < 1 nm)。MM-GBSA结合自由能计算进一步证实了所有配合物的热力学稳定性,相互作用能范围在-30.59 ~ -49.98 kcal/mol之间。这些综合模拟证实,所有鉴定的激动剂复合物保持稳定的结合构象,具有CB1受体激活的最佳相互作用特征。结论:这些结果为研究和开发新的喹唑啉- 2,4 (1H, 3H)-二酮类CB1受体激动剂奠定了基础。

Background: This study examines the types of organizational structures in privately chartered universities in Western Uganda and how these structures impact academic staff performance. Grounded in Henri Fayol's Administrative Management Theory and Vroom's Expectancy Theory, this study integrates structural and motivational perspectives to explore the impact of institutional design on academic operations.

Method: A concurrent triangulation research design was employed to combine quantitative and qualitative approaches. Data were collected from 186 academic staff members using structured questionnaires and 10 academic deans through in-depth interviews.

Results: Quantitative findings revealed that functional and hierarchical structures were the most common, with 55.4% of respondents reporting highly centralized decision-making and 42.5% reporting poor communication flow. A significant positive correlation was observed between organizational structure and academic staff performance (r = 0.512, p < 0.01). Regression analysis showed that organizational structure explained 26.2% of the variance in academic staff performance (R 2 = 0.262, F (1, 184) = 65.46, p < 0.001). Qualitative data supported these results, with participants highlighting that rigid and bureaucratic structures limit flexibility, innovation, and collaboration, whereas excessive centralization undermines academic autonomy ( Yusoff & Isa, 2021).

Conclusion: The study concludes that, while traditional structures dominate private chartered universities, they often hinder academic performance. To enhance staff effectiveness, universities should adopt adaptive and participatory structures ( Berkowitz, 2023). Aligning Fayol's principles of work specialization, centralization, and communication flow with Vroom's motivational framework offers a strategic path for organizational improvement.

背景:本研究考察了西乌干达私立特许大学的组织结构类型,以及这些结构如何影响学术人员的绩效。本研究以法约尔的行政管理理论和弗鲁姆的期望理论为基础,结合结构和动机两个视角,探讨制度设计对学术运作的影响。方法:采用定量与定性相结合的并行三角法研究设计。通过结构化问卷和深度访谈的方式,对186名教职员和10名院长进行了数据收集。结果:定量调查结果显示,职能和层级结构是最常见的,55.4%的受访者表示决策高度集中,42.5%的受访者表示沟通流程不畅。组织结构与教职员绩效呈显著正相关(r = 0.512, p < 0.01)。回归分析显示,组织结构对教职员绩效方差的解释为26.2% (r2 = 0.262, F (1,184) = 65.46, p < 0.001)。定性数据支持这些结果,参与者强调,僵化和官僚结构限制了灵活性、创新和协作,而过度的中央集权会破坏学术自主(Yusoff & Isa, 2021)。结论:研究得出的结论是,尽管传统结构主导着私立特许大学,但它们往往会阻碍学术表现。为了提高员工的工作效率,大学应该采用适应性和参与性结构(Berkowitz, 2023)。将法约尔的工作专业化、集中化和沟通流程原则与弗鲁姆的激励框架结合起来,为组织改进提供了一条战略路径。

Mangroves are ecosystems that link freshwater, land, and oceans. They are also home to vast biodiversity of species and provide vital resources to many coastal communities worldwide. However, in various parts of the world, these natural ecosystems have been subjected to anthropogenic actions that compromise their subsistence. Therefore, the aim of this study was to analyse seasonal changes in vegetation cover in the La Caimanera marsh (Colombia) using remote sensing and satellite sensor imagery. Methodologically, machine learning techniques were used, including semi-supervised and supervised learning, using Landsat, Copernicus, and Planet images. The influence of mangrove vegetation cover on pollutants was explored using remote sensing data and in-situ measurements. The results obtained indicated that in 2015 and 2024, the ecosystem showed stability, with slight reductions in mangrove cover and water bodies. In contrast, a slight increase in urbanized areas was also evident. The NDWI, MNDWI, OC3, and QAA spectral indices were used to monitor water dynamics and water quality. The results reflected stability in water conditions between 2010 and 2020, with a slight reduction in 2023. The increase in chlorophyll-a and reduction in turbidity in 2023 showed alterations in water quality. In addition, the predominance of mature mangrove trees, which comprised 83% of the vegetation, is noteworthy, reflecting a healthy and stable ecosystem. The greater density and homogeneity of the mangrove canopy observed in this study suggests a positive ecosystem response and greater resilience to past environmental changes. It is concluded that the changes experienced by the La Caimanera marsh reflect a balance between conservation and development, highlighting the effectiveness of territorial management policies implemented to maintain the ecosystem's resilience in the face of human pressures.

红树林是连接淡水、陆地和海洋的生态系统。它们也是大量生物多样性的家园,并为世界各地的许多沿海社区提供重要资源。然而,在世界各地,这些自然生态系统受到了危及其生存的人为活动的影响。因此,本研究的目的是利用遥感和卫星传感器图像分析La Caimanera沼泽(哥伦比亚)植被覆盖的季节变化。在方法上,使用机器学习技术,包括半监督和监督学习,使用陆地卫星,哥白尼和行星图像。利用遥感数据和现场测量,探讨了红树林植被覆盖对污染物的影响。结果表明,2015年和2024年生态系统稳定,红树林覆盖面积和水体略有减少;相比之下,城市化地区也明显略有增加。采用NDWI、MNDWI、OC3和QAA光谱指数监测水体动态和水质。结果反映了2010年至2020年期间的水条件稳定,2023年略有下降。2023年叶绿素-a的增加和浊度的降低表明水质发生了变化。此外,值得注意的是,成熟的红树林占植被的83%,反映了一个健康稳定的生态系统。本研究中观察到的红树林冠层密度和均匀性较高,表明生态系统对过去的环境变化具有积极的响应和更强的恢复能力。综上所述,La Caimanera湿地的变化反映了保护与发展之间的平衡,突出了在面对人类压力时实施的领土管理政策在保持生态系统弹性方面的有效性。

Background: Astaxanthin, a red xanthophyll carotenoid, is a powerful antioxidant, anticancer, and glucose and lipid homeostasis regulator. Some pigmented yeasts belonging to the genus Rhodotorula, the well-known yeast for beta-carotene production, have been reported as natural astaxanthin producers. However, the lack of genomic data on astaxanthin-producing strains within these species hinders the identification of biosynthetic routes, molecular characterization of these pathways, and gene editing applications.

Methods: This study explored the diversity and astaxanthin production capability of cultivable pigmented yeast in flower samples. The astaxanthin production ability was inspected by three consecutive methods, including thin-layer chromatography (TLC) for the preliminary step, followed by quantitative spectrophotometry and high-performance liquid chromatography (HPLC) for qualitative validation. The draft genome sequence and astaxanthin-producing genes of astaxanthin-producing yeasts were examined.

Results: Twelve of 23 yeasts from floral samples exhibited natural pigmentation, with colors ranging from pinkish-orange to red, and exhibited the potential for astaxanthin synthesis. These yeasts were Rhodotorula paludigena (three strains) and Rhodotorula mucilaginosa (nine strains). Among R. mucilaginosa strains, HL26-1 had the greatest astaxanthin content (104.98 ± 0.13 μg/g DCW) and yield (0.9280 ± 0.0012 mg/L). Strain LL69-1 has the greatest astaxanthin content (251.78 ± 0.27 μg/g DCW) and yield (1.8632 ± 0.0023 mg/L) among R. paludigena strains. The 18.78 Mbp R. mucilaginosa HL26-1 genome includes 5,711 protein-coding genes. Conversely, the R. paludigena LL69-1 genome was 20.99 Mbp, encompassing 6,782 predicted genes. A comprehensive investigation of draft genome sequences of these two strains identified CrtE, CrtYB, CrtI, CrtS, and CrtR as potential astaxanthin transcription genes.

Conclusion: Here, our results highlight the outstanding potential of two naturally pigmented yeasts, R. mucilaginosa HL26-1 and R. paludigena LL69-1, for astaxanthin production. Furthermore, our findings provide information on the whole genome and protein-encoded genes associated with astaxanthin production, which serve as valuable biological resources for various biotechnological applications.

背景:虾青素是一种红色叶黄素类胡萝卜素,具有强大的抗氧化、抗癌和调节葡萄糖和脂质稳态的作用。一些色素酵母属红酵母属,众所周知的酵母生产β -胡萝卜素,已被报道为天然虾青素的生产者。然而,缺乏这些物种中虾青素产生菌株的基因组数据阻碍了生物合成途径的鉴定、这些途径的分子表征和基因编辑应用。方法:研究花中可培养色素酵母的多样性及其产虾青素能力。采用薄层色谱法(TLC)、定量分光光度法(HPLC)和高效液相色谱法(HPLC)三种方法对虾青素的生产能力进行验证。测定了产虾青素酵母的基因组草图序列和产虾青素基因。结果:23株花卉酵母中有12株表现出天然色素沉着,颜色从粉橙色到红色不等,具有合成虾青素的潜力。这些酵母菌分别是帕鲁迪红酵母(3株)和粘液红酵母(9株)。其中,HL26-1的虾青素含量最高(104.98±0.13 μg/g DCW),产量最高(0.9280±0.0012 mg/L)。菌株LL69-1虾青素含量最高(251.78±0.27 μg/g DCW),产量最高(1.8632±0.0023 mg/L)。mucilaginosa hs26 -1基因组全长18.78 Mbp,包含5711个蛋白编码基因。相反,R. paludigena LL69-1基因组为20.99 Mbp,包含6,782个预测基因。通过对这两种菌株基因组草图序列的综合研究,鉴定出CrtE、CrtYB、CrtI、CrtS和CrtR是潜在的虾青素转录基因。结论:两种天然色素酵母mucilaginosa HL26-1和R. paludigena LL69-1具有生产虾青素的潜力。此外,我们的发现提供了虾青素生产相关的全基因组和蛋白质编码基因的信息,为各种生物技术应用提供了宝贵的生物资源。
