Enriching online flipped classrooms with feedback strategies
Flipped classroom is a type of learning method where students are introduced to content at home while practicing, reflecting, or discussing it in class. In this study, we explore how different feedback strategies impact learning performance, motivation, and satisfaction in online flipped classrooms within a higher education context. Using a quasi-experimental design, 123 undergraduate students were randomly assigned to one of four conditions: teacher feedback, group peer feedback, dialogic peer feedback, and one-way peer feedback. Data were collected using a validated learning performance test, motivation, and satisfaction questionnaire with established reliability. Results indicated that group peer feedback significantly improved students’ learning performance, motivation, and satisfaction compared to other strategies. Additionally, those receiving teacher feedback excelled in the educational dimension of learning and reported greater satisfaction with domain-specific learning. These findings highlight the impact of different feedback strategies on student learning in online flipped classroom environments
Environmental factors affecting the presence of coliform bacteria in water and oysters (Crassostrea cucullata Born, 1778) in Negombo lagoon, Sri Lanka
The recent increase in sewage pollution in the Negombo Lagoon, Sri Lanka, has led to a growing interest in understanding its impact on the local aquatic ecosystem. Physicochemical and general microbiological parameters of the lagoon water (n = 84) were measured at seven sites with contrasted levels of fecal and organic pollution, and their correlation with the presence of total coliform bacteria (TC) was examined. A linear mixed-effect model revealed that heterotrophic bacterial concentrations and electrical conductivity significantly correlated with TC concentrations. Additionally, six individuals of Crassostrea cucullata oysters were sampled from five sites (n = 30) to assess their TC levels and compare their variation across sites. Significant differences in TC levels in oysters were observed across the study sites, with oysters from site S7 located in the Northern part of the lagoon being the most contaminated ones. Fecal indicator bacteria, Escherichia coli, were found to be present across all the studied sites except S5. Additionally, oysters from five sites tested positive for E. coli contamination. The smallest oysters were found at the site most contaminated by microbial load (S2), which may suggest that oysters had decreased filtering activity at the site in response to pollution. Overall, this is the first comprehensive study to provide comparative quantitative data on fecal contamination of oysters in the Negombo Lagoon and its surrounding water.</p
Het ‘free in free out’-principe bij geweld in afhankelijkheidsrelaties
Geweld in afhankelijkheidsrelaties, dat wil zeggen geweld gepleegd door een dader die het slachtoffer niet alleen kent, maar van wie hij of zij materieel, emotioneel of op een andere manier afhankelijk is, is de meest voorkomende vorm van geweld in de samenleving. Bekende uitingsvormen zijn huiselijk en eergerelateerd geweld. De aanpak van deze doorgaans complexe vormen van geweld wordt nog ingewikkelder als betrokkenen ongedocumenteerd zijn, dat wil zeggen dat ze geen verblijfsstatus in Nederland hebben. Daar is al vaker over gerapporteerd, zo ook in dit tijdschrift. Voor ongedocumenteerde slachtoffers is het in de praktijk gehanteerde principe van ‘free in free out’ van groot belang. Met dat principe wordt bedoeld dat ook wanneer mensen niet over een geldige verblijfsstatus beschikken, zij een beroep moeten kunnen doen op de politie als zij hulp zoeken bij slachtofferschap van geweld. Het gaat er dus om dat ongedocumenteerden bij de politie aan kunnen kloppen om een getuigenis af te leggen of melding of aangifte te doen zonder dat zij vanwege hun illegale status worden aangehouden of uitgezet. Van geweld in afhankelijkheidsrelaties weten we dat het vaak lang kan duren voordat slachtoffers bij instanties aan de bel trekken. Schaamte- en angstgevoelens voor wat er is gebeurd en onbekendheid met of gebrek aan vertrouwen in instanties kunnen hierbij een rol spelen. Het moge duidelijk zijn dat dit alles bij mensen zonder een verblijfsstatus nog meer speelt. In de praktijk leven er vragen over dit ‘free in free out’-principe bij professionals die onder meer werkzaam zijn in de opvang voor slachtoffers van geweld in afhankelijkheidsrelaties, bij de politie en in de hulpverlening aan ongedocumenteerden. Geldt het principe bijvoorbeeld alleen als het slachtoffer zelf melding of aangifte doet, of is het ook van toepassing als een bezorgde derde een appèl op de politie wil doen, en wat is eigenlijk de juridische status van dit principe
Obereit's Nihilism:Inventing or Diagnosing a Social Sickness?
AbstractThis paper provides an overview of Jakob Hermann Obereit’s introduction of the philosophical term nihilism from 1787 up to 1791. It argues that this introduction is part of a project called the desperate metaphysics, which is partly a response to the reception of Immanuel Kant’s Critique of pure Reason , but also an assessment of the rise of a focus on individual responsibility, development and autonomy that had been put forward during the Enlightenment. In this sense, nihilism is introduced in response to a philosophical discussion that is understood as drawing out the depths of these Enlightenment demands and the untenability of traditional metaphysics, explaining the immediate appeal of the term and its rapid spread beyond philosophy

The challenge of assessing the needs of vulnerable populations in public health:Promoting an approach grounded in proportionate universalism principles
AIM: Health inequities persist as a pressing public health challenge, often rooted in unequal access to resources, opportunities and privileges that disproportionately affect vulnerable populations. Proportionate universalism offers a promising approach by advocating for universal health interventions that adjust in scale and intensity to meet varying levels of needs. Despite its potential, implementing proportionate universalism in health promotion remains challenging, particularly when narrowly assessing vulnerability using socioeconomic indicators alone, which can misclassify or stigmatise vulnerable groups and perpetuate inequities. This commentary reflects on these challenges in the context of developing a smoking prevention intervention for adolescents facing societal vulnerability and proposes more nuanced strategies for assessing needs within a proportionate universalism framework.CONCLUSIONS: This article highlights the complexity of defining and assessing vulnerability in public health research and practice. By sharing insights from our research process, we advocate for a broader understanding of adolescent vulnerability that moves beyond traditional socioeconomic measures. We hope to inspire more inclusive and equitable health promotion interventions that are responsive to the diverse and intersecting forms of disadvantage individuals may experience. </p
Valuation of Ecosystem Services by Local Communities Around Matang Mangrove Forest Reserve, Malaysia
Matang Mangrove Forest Reserve (MMFR) on the west coast of Peninsular Malaysia is one of the longest managed mangrove forests for sustainable charcoal and pole production. To understand the interactions between nearby communities and the mangrove ecosystem, a systematic sampling of the houses for questionnaire-based interviews was conducted, and the data were analyzed through multiple correspondence analysis and group comparison tests. In general, Malay communities have higher mangrove-related knowledge and utilization levels than Chinese communities. Out of 124 respondents, 31% use mangroves as fuel, 44% for construction material, 13% for medicine, and 2% for food, drinks, or animal feed. Although personal collection is limited, there is a heavy reliance on mangrove charcoal and poles purchased from the market. While being a major (wood) production forest, the mangrove reserve is also an important fishing ground for 56% of the respondents, where trawler encroachment and the use of illegal fishing gear are common problems. Respondents observed sea level rise, sedimentation, and pollution in the area; depopulation is a prominent problem for some Chinese communities. Our findings show that coastal mangrove fishing communities are facing new environmental and social challenges; thus, supportive policies should be in place to ensure their livelihood and wellbeing
