Emerging Anthelmintic Resistance in Poultry: Can ethnopharmacological approaches offer a solution?
Limited pharmacological studies have been conducted on plant species used against poultry helminths. The objective of this study was to provide a basis for plant based anthelmintics as possible alternatives against poultry anthelmintic resistance. The study justified the need for alternative anthelmintics. The study places emphasis on the increasing anthelmintic resistance, mechanism of resistance, and preparational protocols for plant anthelmintics and their associated mechanism of action. Pharmaceutical studies on plants as alternative therapies for the control of helminth parasites have not been fully explored especially in several developing countries. Plants from a broad range of species produce a wide variety of compounds that are potential anthelmintics candidates. Important phenolic acids have been found in Brassica rapa L. and Terminalia avicenniodes Guill. and Perri that affect the cell signaling pathways and gene expression. Benzo (c) phenanthridine and isoquinoline alkaloids are neurotoxic to helminths. Steroidal saponins (polyphyllin D and dioscin) interact with helminthic mitochondrial activity, alter cell membrane permeability, vacuolation and membrane damage. Benzyl isothiocyanate glucosinolates interfere with DNA replication and protein expression, while isoflavones from Acacia oxyphylla cause helminth flaccid paralysis, inhibit energy generation, and affect calcium utilization. Condensed tannins have been shown to cause the death of nematodes and paralysis leading to expulsion from the gastro-intestinal tract. Flavonoids from Chenopodium album L and Mangifera indica L act through the action of phosphodiesterase and Ca(2+)-ATPase, and flavonoids and tannins have been shown to act synergistically and are complementary to praziquantel. Artemisinins from Artemisia cina O. Berg are known to disrupt mitochondrial ATP production. Terpenoids from Cucurbita moschata L disrupt neurotransmission leading to paralysis as well as disruption of egg hatching. Yeast particle encapsulated terpenes are effective for the control of albendazole-resistant helminths

Reflecting gendered experiences of student-staff partnership: a student standpoint using poetic transcription
© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. Debates in higher education problematise the role of students as passive receivers of education. In the student engagement field, some scholars argue that students should be positioned as ‘partners’ or ‘change agents’ rather than ‘customers’ or ‘consumers’. However, the opportunities for students to self-author their experiences as subjects rather than objects of engagement in mainstream publications is rare. Drawing on standpoint theory, we–three students from international contexts–argue that if students are to shape higher education discourses, then students’ work needs to be more prominent in mainstream academic publishing. We exemplify one approach to alternate forms of conducting and sharing student-led research by exploring and representing our own experiences of gender in student-staff partnership through poetic transcription. In doing so, we hope to disrupt some of the dominant assumptions around the positioning of students as objects and the validity of students’ self-authored voices in higher education discourses
Mind the (gender) gap: engaging students as partners to promote gender equity in higher education
Gender inequity remains a critical issue in higher education. We explored the proposition that engaging students as partners (SaP), an increasingly adopted approach to student engagement, may present one approach to improving gender equity by fostering agency and leadership for women. First, we analyzed the gender distribution of authors of SaP scholarship spanning 202 articles published in six academic journals over the past five years. Women were more likely to author (70%) and lead (76%) SaP publications. Second, we used collaborative autoethnography to explore our experiences as three women SaP practitioners. Affirmative partnerships built our agency to assert our voices and empowered us to advocate for gender equity. These data indicate that SaP may present one approach to promoting gender equity by creating ‘brave spaces’ and ‘sites of resistance’ against gendered norms in academia

Toward theories of partnership praxis: an analysis of interpretive framing in literature on students as partners in teaching and learning
© 2018, © 2018 HERDSA. A body of literature on students as partners (SaP) in higher education has emerged over the last decade that documents, shares, and evaluates SaP approaches. As is typical in emerging fields of inquiry, scholars differ regarding how they see the relationship between the developments in SaP practices and the theoretical explanations that guide, illuminate, and situate such practices. In this article we explore the relationship between theory and practice in SaP work through an analysis of interpretive framing employed in scholarship of SaP in teaching and learning in higher education. Through a conceptual review of selected publications, we describe three ways of framing partnership that represent distinct but related analytical approaches: building on concepts; drawing on constructs; and imagining through metaphors. We both affirm the expansive and creative theorising in scholarship of SaP in university teaching and learning and encourage further deliberate use and thoughtful development of interpretive framings that take seriously the disruptive ethos and messy human relational processes of partnership. We argue that these developmental processes move us toward formulating theories of partnership praxis
