In the context of global democratic crises and pervasive neoliberal policies, civil society organizations (CSOs) play a critical role in promoting democratic processes and advancing social change on local, national, and transnational scales. However, such organizations also (need to) grapple with how they themselves put social justice and democratic principles into practice, and resist coloniality within. This article examines these questions in the case of People Powered-Global Hub for Participatory Democracy, a recently found transnational CSO that advocates globally for participatory democracy as a mechanism for social change and employs these principles in its own governance and operations. The analysis focusses on the creation of People Powered and its first year of practice. Drawing upon decolonial frameworks-and based on our own experiences as founding members of People Powered and our reading of interviews and documents-we identify concrete practices through which the organization seeks to enact epistemic justice, shift power, and emphasize relationality. We argue that People Powered's decolonial roots, collectively articulated values and commitments, radical transparency, and its consistent employment of meaningful participation and reflexivity have built and are likely to sustain this transnational solidarity for social change. At the same time and perhaps critical for fostering solidarity and social change in the long term, People Powered embraces, rather than evades, tensions and contradictions that emerge in these efforts.

OBJECTIVE
To analyze the early effectiveness of unilateral biportal endoscopic discectomy (UBED) combined with annulus fibrosus suture in the treatment of lumbar disc herniation (LDH).
METHODS
The clinical data of 19 patients with LDH treated with UBED and annulus fibrosus suture between October 2020 and October 2021 were retrospectively analyzed. There were 12 males and 7 females with an average age of 39.1 years (range, 26-59 years). The operative segment was L in 13 cases, and L , S in 6 cases. The mean disease duration was 6.7 months (range, 3-15 months). Preoperative neurological examination showed that muscle strength, sensation, and tendon reflex weakened or disappeared in varying degrees. Single annulus fibrosus suture (14 cases) or anchor assisted annulus fibrosus suture (5 cases) was selected according to the location of annulus fibrosus tears. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months, and 6 months after operation. Oswestry disability index (ODI) was used to evaluate the function recovery of lumbar spine before operation and at 3 days, 3 months, and 6 months after operation. At 3 days and 3 months after operation, MRI was used to examine the removal of nucleus pulposus and decompression of nerve root. MacNab criteria was used to evaluate the effectiveness at 6 months after operation and the recovery of nerve root function was recorded.
RESULTS
All operations were successfully completed with a mean operation time of 52.7 minutes (range, 40-75 minutes). There was no complication such as nerve injury, spinal cord hypertension syndrome, or dural sac tear during operation, and no complication such as infection, aggravation of nerve damage, or cerebrospinal fluid leakage after operation. All the patients were followed up 6-10 months (mean, 8.2 months). Postoperative MRI showed that the herniated disc was completely removed and nerve roots were fully decompressed. During the follow-up, there was no recurrence of disc herniation. The VAS scores of low back pain and leg pain and ODI at each time point after operation significantly improved when compared with those before operation, and those at 6 months after operation further improved than those at 3 days and 3 months after operation, all showing significant differences ( <0.05). At 6 months after operation, MacNab standard was used to evaluate the effectiveness, and the results were excellent in 14 cases, good in 4 cases, and fair in 1 case, with an excellent and good rate of 94.7%. Neurological examination showed that the sensation and muscle strength of the affected nerve root innervated area recovered significantly when compared with those before operation ( <0.05); the recovery of tendon reflex was not obvious, showing no significant difference when compared with that before operation ( >0.05).
CONCLUSION
UBED combined with annulus fibrosus suture is a safe and effective technique for LDH and early effectiveness is satisfactory.

The appropriateness of the paradigm underlying competency frameworks and their specific application in the list of definitions developed by a Task Group of Society for Community Research and Action (SCRA) for US community psychologists need further consideration. This paper considers the technicist and behavioural roots of some of these concepts, illustrating tensions when applying them to community psychology. It then proposes a competency perspective from the global South. Drawing from focus group discussions with, and written reflections from, postgraduate Master's students in training as clinical and counselling psychologists, this paper builds inductively from the recorded data. Following a template analysis of the material, four integrating themes were evident. The distinctive nature of community psychology is highlighted through the themes: relational foundations, activity evolution, self-management and the awareness and influences of processes. Proposals for an alternative framework ("RASP") are based on its emergence from the applications of learning to practice, emphasising community-based principles. The importance of reflection as the basis for the learning is highlighted. The imperatives to foreground social justice and to enable reflexive thinking on action are discussed, along with concepts based on Humanist and Social Constructivist paradigms, to lead to more interactive and inclusive processes in work on competencies.

PURPOSE
Clinical reasoning has been taught, practised, and researched under Western epistemologies, which have been fallible in addressing the complexity of clinical reasoning within Indigenous cultures and societies. We explored how speech-language pathologists in Sri Lanka negotiate and value Indigenous and Western perspectives in clinical reasoning within a decolonial framework.
METHOD
This study used participatory research methodology within the decolonised qualitative research paradigm to produce data collaboratively with eight Sri Lankan speech-language pathologists. Oral history narratives and object-based textual reflections generated the necessary data for the study. Systematic visual-textual analysis and reflexive thematic analysis were carried out iteratively, and the data analysis and interpretation were undertaken collaboratively with the participants.
RESULT
We generated four key themes about professional education, individuality in practice, holistic thinking, and balancing interests and priorities. The results demonstrate that social, political, and economic forces impact practitioners' clinical reasoning.
CONCLUSION
Practising science in its original form within Indigenous contexts is challenging. Colonial roots and imperialism impact the delivery of appropriate services in socially and politically marginalised communities. Practitioners' self-awareness about authentic identities and practical wisdom can develop culturally relevant knowledge for equitable practice.

The ability of a chemical reaction network to generate itself by catalyzed reactions from constantly present environmental food sources is considered a fundamental property in origin-of-life research. Based on Kaufmann's autocatalytic sets, Hordijk and Steel have constructed the versatile formalism of catalytic reaction systems (CRS) to model and to analyze such self-generating networks, which they named reflexively autocatalytic and food-generated. Recently, it was established that the subsequent and simultaenous catalytic functions of the chemicals of a CRS give rise to an algebraic structure, termed a semigroup model. The semigroup model allows to naturally consider the function of any subset of chemicals on the whole CRS. This gives rise to a generative dynamics by iteratively applying the function of a subset to the externally supplied food set. The fixed point of this dynamics yields the maximal self-generating set of chemicals. Moreover, the set of all functionally closed self-generating sets of chemicals is discussed and a structure theorem for this set is proven. It is also shown that a CRS which contains self-generating sets of chemicals cannot have a nilpotent semigroup model and thus a useful link to the combinatorial theory of finite semigroups is established. The main technical tool introduced and utilized in this work is the representation of the semigroup elements as decorated rooted trees, allowing to translate the generation of chemicals from a given set of resources into the semigroup language.

BACKGROUND
Axo-axonic contacts onto central terminals of primary afferents modulate sensory inputs to the spinal cord. These contacts produce primary afferent depolarization (PAD), which serves as a mechanism for presynaptic inhibition, and also produce dorsal root reflexes (DRRs), which may regulate the excitability of peripheral terminals and second order neurons. We aimed to identify changes in these responses as a consequence of peripheral inflammation.
METHODS
In vitro spinal cord recordings of spontaneous activities in dorsal and ventral roots were performed in control mice and following paw inflammation. We also used pharmacological assays to define the neurotransmitter systems implicated in such responses.
RESULTS
Paw inflammation increased the frequency and amplitude of spontaneous dorsal root depolarizations, the occurrence of DRRs and the amplitude of ventral roots depolarizations. PAD was classified in two different patterns based on their relation to ventral activity: time-locked and independent events. Both patterns increased in amplitude after paw inflammation, and independent events also increased in frequency. The circuits that were responsible for this activity implicated both glutamatergic and GABAergic transmission. Adrenergic modulation differentially affected both types of PAD, and this modulation changed after paw inflammation.
CONCLUSIONS
Our findings suggest the existence of independent spinal circuits at the origin of PAD and DRRs. Inflammation modulates these circuits differentially, unveiling varied mechanisms of spinal sensitization. This in vitro approach provides an isolated model for the study of the mechanisms of central sensitization and for the performance of pharmacological assays with the purpose of identifying and testing novel antinociceptive targets.
SIGNIFICANCE
Spinal circuits modulate activity of primary afferents acting on central terminals. Under in vitro conditions, dorsal roots show spontaneous activity in the form of depolarizations and action potentials. Our findings are consistent with the existence of several independent generator circuits. Experimental paw inflammation reduced mechanical withdrawal threshold and significantly increased the spontaneous activity of dorsal roots, which may be secondary to an enhanced output of spinal generators. This can be considered as a novel sign of central sensitization.

Spontaneous interneuron activity plays a critical role in developing neuronal networks. Discharges conducted antidromically along the dorsal root (DR) precede those from the ventral root's (VR) motoneurons. This work studied whether spinal interneurons project axons into the neonate's dorsal roots. Experiments were carried out in postnatal Swiss-Webster mice. We utilized a staining technique and found that interneurons in the spinal cord's dorsal horn send axons through the dorsal roots. In vitro electrophysiological recordings showed antidromic action potentials (dorsal root reflex; DRR) produced by depolarizing the primary afferent terminals. These reflexes appeared by stimulating the adjacent dorsal roots. We found that bicuculline reduced the DRR evoked by L5 dorsal root stimulation when recording from the L4 dorsal root. Simultaneously, the monosynaptic reflex (MR) in the L5 ventral root was not affected; nevertheless, a long-lasting after-discharge appeared. The addition of 2-amino-5 phosphonovaleric acid (AP5), an NMDA receptor antagonist, abolished the MR without changing the after-discharge. The absence of DRR and MR facilitated single action potentials in the dorsal and ventral roots that persisted even in low Ca2+ concentrations. The results suggest that firing interneurons could send their axons through the dorsal roots. These interneurons could activate motoneurons producing individual spikes recorded in the ventral roots. Identifying these interneurons and the persistence of their neuronal connectivity in adulthood remains to be established.

INTRODUCTION
We will launch a national survey in Serbia to document the prevalence of two types of questionable health behaviours: (1) intentional non-adherence to medical recommendations and (2) use of traditional, complementary and alternative medicine practices, as well as the relation between the two. We will also investigate their psychological roots, including (a) 'distal' predictors such as HEXACO personality traits (plus Disintegration) and thinking dispositions (rational/experiential thinking and cognitive reflexivity), and (b) 'proximal' predictors under the umbrella 'irrational mindset' (set of unfounded beliefs consisting of conspiratorial thinking, superstition, magical health beliefs as well as selected cognitive biases), which have more content-wise overlap with the health behaviours.
METHODS AND ANALYSIS
In this cross-sectional study, a research agency will collect data from a nationally representative sample (n=1043; age 18-75 years; estimated start/end-June/November 2021) recruited online (approximately, 70% of the sample, aged 18-54; 11 years) and face-to-face (approximately, 30% of the sample, aged 55-75 years). Participants will complete a battery of tests assessing questionable health behaviours, basic personality traits, thinking dispositions, irrational mindset, sociopolitical beliefs, sociodemographic and health-related variables. Prevalence rates will be calculated using descriptive statistics. To explore the relation between (psychological) predictors and questionable health behaviours, we will use hierarchical regression and partial mediation models (path analysis or full SEM models).
ETHICS AND DISSEMINATION
Ethical Committees of the Faculty of Philosophy in Belgrade (#935/1), Faculty of Special Education and Rehabilitation (#139/1) and Faculty of Media and Communications (#228) approved the protocol. Only participants who provide informed consent will participate in the study. A research report based on the study results will be submitted to peer-reviewed journals and results will be made available to stakeholders through reports on the project website https://reasonforhealth.f.bg.ac.rs/en/ and disseminated via social media.

Food waste is a global issue with major environmental and socio-economic implications. The problem is even worse in Arab countries where tremendous amounts of food are wasted everyday. In this study, we engaged in an ethnographic journey documenting meal management practices in rural Lebanese households as they relate to food waste. We interviewed 60 women from the Chahhar region (closest communities to the nation's largest landfill) who are in charge of their households' food management. We kept detailed reflexive notes of observations and photo-journaled the provision, preparation, preservation, consumption, and disposal of food. We found that despite the enormity of the food waste crisis in Lebanon, the environmental impact was strikingly absent from the participants' construction of food-related practices. Yet, the women exhibited a strong food waste averse behavior rooted in cultural norms and religious beliefs built on active avoidance of food waste. Our findings shed the light on the intricate connections of family and community routines anchored in frugality and hospitality practices.

Integration of an advanced practice nurse into a primary care practice: a qualitative analysis of experiences with changes in general practitioner professional roles in a Swiss multiprofessional primary care practice.
BACKGROUND
The complex care needs of people with chronic illnesses and multimorbidity pose a significant challenge to the Swiss primary care system. Ensuring efficient, high-quality care will require new care models. Internationally, the integration of advanced practice nurses (APNs) into primary care models has shown promising results. The current study investigates how general practitioners (GPs) in Switzerland experience the integration of APNs into their primary care teams with respect to their own professional roles.
METHODS
We used a qualitative, social-constructivist approach, focusing on six individual interviews with general practitioners within the frame of a larger study including GPs and APNs in a Swiss multiprofessional primary care practice. Data were analysed following Braun and Clarke's approach for reflexive thematic analysis.
SETTING AND PARTICIPANTS
The study took place between August 2019 and February 2020 in a Swiss multiprofessional primary care practice that had been working with APNs for nine years. Participants included six general practitioners.
RESULTS
We identified three main themes characterising Swiss GPs' experiences with the integration of APNs into their primary care team: (1) trust as foundation for collaboration with APNs; (2) build-up of the APN role by delegation, teaching, and supervision, investing time particularly at the beginning of their collaboration with the APN - a time investment that declined significantly as the APNs' competencies grew - and (3) synergies of partnership-based collaboration with APNs. Physicians who were experienced teachers and supervisors, and who delegated tasks based on who would be able to fulfil them most efficiently and effectively, experienced not only a broad range of synergies, but also possibilities to further develop the range of their own activities. Comprehensive, high-quality patient care was perceived as a particular added value.
CONCLUSION
Our analysis revealed that GPs experienced interprofessional synergies when working collaboratively with APNs. These were rooted in trust and relied on abilities in teaching, supervision and delegation to achieve maximum impact. Capitalising on the integration of APNs into primary care, this new care model can be adapted to diverse individual settings. We conclude this article by highlighting the potential of working collaboratively with APNs, who play increasingly important roles in the primary care of polymorbid patients with complex needs.
