Authors: Ahmad Musrab Muhamad Wafi , Abu Yazid Auni Hasyilah , Mohd Mokhtar Nadzirah
Published: October 2024

Solid wastes generated from the oil palm industry contain valuable nutrients like nitrogen, phosphorus, and potassium that can significantly enhance plant growth and potentially elevate fertilizer production. This study aims to identify the optimal formulation of liquid organic fertilizer (LOF) derived from oil palm empty fruit bunch (OPEFB) fiber waste. Three formulations of LOF were prepared, comprising OPEFB waste, molasses, noni fruit, and cattle urine, designated as Formulation A, B, and C. These formulations underwent a 14-day anaerobic incubation period. The formulated OPEFB LOF was then analyzed for nutrient content, electrical conductivity, and total dissolved solids. This study also examines the soil properties and plant growth outcomes following the application of the formulated OPEFB LOF. The results indicated that Formulation A exhibited the highest nutrient concentrations, specifically 485 ppm nitrogen, 95 ppm phosphorus, and 1007 ppm potassium. In comparison to the other two OPEFB LOF formulations, Formulation A showed the lowest values for total dissolved solids (502 ppm) and electrical conductivity (8.14 dS/m). The findings demonstrated that Formulation A displayed the most favorable growth characteristics in terms of leaf count, plant height, leaf length, and leaf width. This is attributed to the nitrogen-boosting properties of cattle urine, along with the complementary effects of molasses and noni fruit as soil improver and bio-activator. This study confirms the viability of utilizing green organic fertilizer derived from OPEFB substrate in agriculture, replacing conventional inorganic fertilizers.

A noise barrier serves as a method to control noise pollution resulting from road traffic, particularly prevalent in rural areas near heavy traffic routes such as highways. This study focuses on simulating the sound Insertion Loss (IL) of existing noise barriers designed to mitigate road traffic noise around school areas. The primary goal is to assess the precision of the Finite Element Modeling (FEM) program. Utilizing the finite element analysis software, COMSOL, the study models the noise barrier and its surroundings in two-dimensional acoustic radiation problem based on on-site dimensions and parameters. By examining the often-neglected aspect of noise leakage and its impact on noise reduction, the research aims to provide specific guidance for urban planners and architects to optimize noise mitigation in various urban settings. The study reveals a strong agreement between the simulated IL and on-site measurements, with a minimal difference ranging from 0.4 dB to 1.1 dBA on average. Additionally, the research suggests potential improvements to simulation accuracy through adjustments in aperture sizes. The findings demonstrate that finite element simulation can be a valuable tool for designers to assess the effectiveness of noise barriers before construction begins.

Published: October 2024

World Health Organization (WHO) recognised musculoskeletal disorder (MSD) as the main contributor to disability worldwide, with low back pain as the major disorder globally. The occupational disorder normally occurs during lifting. The weight of the load and manual handling tasks during lifting has an impact on the spine and joint torque. The purpose of this study is to propose a dynamic model of the spine that can estimate the vertebral joint torques. This study is a bimodal approach that consists of the experimental and theoretical parts. Ten healthy UniMAP students (10 males) participated in this study. The subjects were required to lift a 3kg weight plate for kinematics and EMG data collection. Retro-reflective markers were attached to the subject body, and then, the data was collected and stored in QTM software. Kinematic data was processed using C-Motion Visual3D. Eight Trigno Wireless Sensors were attached on the back muscles (left and right erector spinae, latissimus dorsi, external oblique and internal oblique). The EMG data were stored in EMG Acquisition software and subsequently, were processed using EMG Analysis software. Gordon’s method was used to develop a mathematical model of the spine. The model comprises of five kinematic chains which connected three lumbar, two thoracic and one cervical. The model calculated the value of joint torque on flexion/extension movement using Matlab and Microsoft Excel. When calculated on L5, the model gives an estimation within 0 – 30 kgm2s-2. The model was further used to estimate value of L3, L1, MAI and T2. The estimate average value of joint torque at L3 is within 5 – 25 kgm2s-2, MAI is within 0 – 6 kgm2s-2 and T2 is within 0 – 1 kgm2s-2. The average RMS values show the highest muscle activity on the right internal oblique muscle (1519 µV), followed by the right external oblique (1166 µV) and left external oblique (418 µV). The results obtained gives an insight on the value of joint torque that have been applied by the spine and the most activated back muscles during lifting.

Published: October 2024

Hydrogels are still relevant instruments that can support and improve the dynamic biological process of wound healing. This paper modified hydrogel film by combining polyvinyl alcohol (PVA), halloysite nanotube (HNT), and collagen using simple freeze-thawing and spin-coating techniques. The modification aims to improve the physiochemical and in-vitro bioactivity of the PVA/HNT hydrogel films via the inclusion of different concentrations of collagen. 0.092 mm PVA/HNT/Col3 hydrogel film was suggested to have excellent morphological properties with 94.11 % porosity. It also has good tensile properties with excellent hydrophilicity performance at 38.40o contact angle and 83.528% swelling capacity compared to other modified films. In-vitro bioactivity suggested that the PVA/HNT/Col3 are safe and non-toxic toward host tissue and can promote healing at 93.12% wound closure after 24 hours of treatment. Hence, this material displays huge potential as a wound healing matrix template.

Published: October 2024

This study presents a detailed numerical analysis of substrate boards made from various materials (FR-4, Si cladding, and Cu cladding) with nine electronic components mounted on them. Each component is subjected to different heat fluxes, and the analysis covers both natural convection (NC) and forced convection (FC) modes of heat transfer at air velocities of 4m/s and 6m/s. The findings reveal that at an air velocity of 6m/s, using a copper cladding board significantly lowers the temperatures of the electronic components by 340C to 540C compared to FR-4 and Si cladding boards. Additionally, the copper cladding reduces the required air-cooling velocity by 2m/s and achieves a temperature reduction for the IC chips ranging from 3.500C to 13.120C. It is recommended to use an air velocity of 4m/s with copper cladding to minimize fan power consumption while maintaining component temperatures below 1250C. These results provide crucial insights for thermal design engineers, aiding in the selection of appropriate substrate boards for effective thermal management of electronic components. The study emphasizes the benefits of copper cladding in distributing heat more uniformly, reducing energy consumption, and maintaining optimal operating temperatures. Furthermore, it suggests that placing high heat-dissipating components at inlet or outlet points can minimize thermal interactions and overall configuration temperatures. The research offers valuable guidance to the heat transfer community, particularly electronic thermal designers, by highlighting the importance of substrate material choice and component placement in enhancing the reliability and lifespan of integrated circuits (ICs). The comprehensive analysis and recommendations serve as a vital resource for optimizing thermal control strategies in electronic devices, ultimately contributing to improved performance and durability.

The heating pad was a mechanism for heating elements using steam as a heat source and heating the liquid inside a flexitank to liquidise for easy discharge completely. Alternative heat sources such as infrared, electric, and exothermic reactions may improve thermal performance for the heating process. Infrared heating is chosen for this study due to its efficient radiation heat transfer compared to conduction and convection. This study aims to determine the optimal infrared heater configuration to improve the time to liquidify fluid on the flexitank for easier discharge. Nine flexitank and infrared heater geometries were made using SolidWorks with different heater positions and heating element thicknesses. Each geometry was simulated using Ansys Mechanical to study the thermal performance of radiation heat transfer with three different heating element materials. The heat output and energy input obtained from the simulation were used to calculate heating time and energy efficiency, respectively. The effects of each parameter were studied to determine the best configuration of the infrared heater in terms of heating time, energy consumption and both. The results showed that the position of the heater plays the most crucial role in determining the heating time and energy consumption, as a heater position that produces a larger heated surface area on the flexitank can reduce heating time. The thickness of the heating element and its material contributes a minor impact on heating time and energy consumption. Increasing thickness would lower the heating time and increase energy efficiency if the thickness improves heat retention capabilities. Increasing material emissivity will increase the heating time. Higher conductive materials would use more energy compared to lower conductive materials. The heating time was improved by about 30% compared to a steam heating pad. Energy consumption was reduced by about 85% compared to a small steam generator. In conclusion, the infrared heater was a promising alternative as a heat source for flexitank applications.

Published: October 2024

Penelitian ini bertujuan untuk mengukur hubungan antara workplace incivility (ketidakacuhan dalam hubungan kerja) dan job stress (stres kerja) di lingkungan pendidikan tinggi di Kota Pontianak. Tingginya beban kerja yang ada sering kali memunculkan perilaku workplace incivility, terutama dalam konteks kerja tim. Hal ini juga berlaku di lingkungan perguruan tinggi, di mana komunikasi dan kerja sama dalam tim sering terjadi. Selain itu, peran moderasi emotional intelligence (EI) juga akan diteliti untuk memahami sejauh mana EI dapat mengurangi dampak negatif ketidaksopanan dalam hubungan kerja terhadap stres kerja. Metode pengolahan dan analisis data yang digunakan adalah metode kuantitatif. Teknik purposive sampling digunakan dalam pengambilan sampel. Jumlah minimum responden yang ditetapkan adalah 100 orang. Hasil penelitian ini menunjukkan adanya pengaruh positif dan signifikan antara workplace incivility dalam hubungan kerja dan job stress. Semakin tinggi tingkat ketidaksopanan yang dirasakan, semakin tinggi tingkat stres kerja yang dialami individu. Namun, kecerdasan emosional tidak memoderasi hubungan antara ketidaksopanan dalam hubungan kerja dan stres kerja. Meskipun kecerdasan emosional memiliki peran penting dalam mengelola emosi, penelitian ini menunjukkan bahwa hal tersebut tidak memperkuat atau melemahkan hubungan antara ketidaksopanan dalam hubungan kerja dan stres kerja di kalangan karyawan pendidikan tinggi di Kota Pontianak.

Published: October 2024

The study examines the implementation of credit guarantees and how their barriers affect small and medium enterprises' (SMEs) access to finance in Malawi. The study reviews widely existing literature from academic research, policy frameworks, and reports from governmental and nongovernmental bodies. Additionally, the study uses primary data collection methods, in which interview and survey techniques are applied to cover the whole spectrum of stakeholders: SME owners, financial institutions, government functionaries, and development partners. This study uses a qualitative approach to examining how credit guarantees affect small businesses' ability to access capital and how well they do after it. Qualitative techniques include thematic coding of interview transcripts and policy documents, and quantitative techniques include using statistical tools. In so doing, the paper brings to light credit guarantees, which are essential in broadening the financial horizons of SMEs in Malawi. Major barriers to accessing finance include a lack of collateral, poor credit history, and exorbitant interest rates which become stumbling blocks for SMEs to secure loans from mainstream financial institutions. It further identifies the critical role of government policies and programs in supporting SMEs' financial inclusivity and offers measures to enhance credit guarantee mechanisms' effectiveness.

Authors: Tutani Tanaka , Tandawa Masasa Richard , Chirambiwa Benjamin , Chipomho Justin
Published: October 2024

Rape (Brassica napus) is an important vegetable crop grown by smallholder farmers in Zimbabwe to achieve food and nutritional security. However, productivity and quality of rape are greatly dampened by aphids which reduce its palatability and quality. Chemical pesticides, while effective, pose environmental risks and can lead to pest resistance and resurgence, besides residual effects and bioaccumulation along the food chain. Tomato leaves are rich in phenolic and flavonoid compounds, that have shown promise as a botanical pesticide against aphids in other crops. This research aimed to establish the aphicidal components in tomato leaf extract using TLC and UV-Vis Spectroscopy; establish toxicity of the extract using laboratory bioassay, investigate the potential of different concentrations of tomato leaf extracts as a natural, environmentally friendly and sustainable approach to pest management against aphids in rape production at Kushinga Phikelela Agricultural College in Zimbabwe. A CRD with four treatments (0%, 20%, 40% and 60% of tomato leaf extract) and distilled water (negative control) replicated five times each was used. Aphid infestation (scored on a scale of 0-9), yield, leaf size, and plant height were measured fortnightly. Data was analysed for statistical significance using ANOVA while separation of significant means was done by Fisher’s Protected Least Significant Difference Test (LSD (5%). The results from combined analysis using TLC and UV- Vis Spectroscopy indicated that tomato leaf extract used in this research contained compounds (Solanine, Tomatine, Chaconine) which are known to be toxic to pests. There was a highly significant (p<0.001) difference among treatments on aphid mortality. The highest aphid mortality (95.57%) while the lowest (4%) was observed in 60% and 0% leaf extract respectively. Aphid infestation, leaf size and plant height were highly significant (P<0.001) during weeks 4, 6, 8 and 10 after transplanting. Aphid infestation in week 10 mean score was 8.8, 6.2, 3.8 and 0.8 for 0%, 20%, 40% and 60% tomato leaf extract respectively. Other parameters such as yield and leaf size were highest in the plots that received 60% tomato leaf extract sprays. Highly significant difference (P<0.001) in yield was observed in weeks 8 and 10, while significant difference (P<0.05) in yield was noted in weeks 4 and 6. However, in week two there were no significant differences among the treatments in yield and aphid infestation. Tomato leaf extracts contain secondary metabolites toxic to aphids and this can be used by resource constrained farmers. We recommend the use 60% tomato leaf extracts to control aphids in rape to sustainably achieve high yields.

Authors: SOYATA Kıymet , ATEŞ Aysel
Published: October 2024

This action research was designed to examine the professional development program (PDP) of lecturers and the effects of the program’s processes on educational administrators and lecturers. The study involved 2 administrators and 10 lecturers from an English preparatory school at a private university in Istanbul. During the program, to gather insights into the achievements, challenges, and suggestions related to the program, semi-structured one-on-one interviews and focus group discussions were conducted with administrators and lecturers, alongside the use of reflective journals and observation forms. Content analysis was employed to analyze the data. Education administrators believe that the PDP enhanced internal communication within the organization, provided insights into organizational functioning, fostered the adoption of student-centered teaching methods, and contributed to the personal development of lecturers through self-criticism and increased self-confidence. Lecturers highlighted benefits such as experience sharing, critical thinking enhancement, student-centered teaching integration, and improved teaching skills. Time management is a common challenge for both administrators and lecturers, with the added concern among lecturers about being perceived as ineffective by students during teaching observations. In light of the findings, it is recommended to tailor activities to lecturers’ needs, offer a flexible program structure, and provide support mechanisms to help lecturers cope. Future research might involve larger samples and explore emotional states and challenges independently.

Extending the Marshallian industrial districts framework: framing types of multinationals
Authors: Hervás Oliver José Luis , Boronat Moll Carles , Eizaguirre Maria , Marquez Garcia Juan Antonio
Published: October 2024

In this study, we reflect on multinationals and their challenge to the established paradigm of Marshallian Industrial Districts (MIDs). Recently, scholars have begun to show a reorientation of the MID framework towards addressing topics that were not central to the mainstream MID framework, such as multinationals. We elaborate on and discuss the effects of multinationals in districts, a topic that demands further research and theoretical integration. We argue that future research should delve into questions around the development and empirical testing of multinationals in MIDs, proposing new lines of inquiry to strengthen the MID framework.
A global assemblage of tax haven clusters: profit shifting, tax dodging and money laundering
Authors: Boix-Domenech Rafael , Cooke Philip
Published: October 2024

In this paper we explore a selection of tax haven clusters in the US and Europe as diverse but recognisable species of some fifty of the phenomena worldwide that have been seldom studied from an economic geography or spatial planning viewpoint. We treat the objects of study as being almost perfect expressions of the classical, canonical cluster configuration. They are: spatial agglomeration, untraded as well as market dependencies, small and medium-sized enterprise status, associative or agentic relationships, interaction with large firms inside or outside the cluster and knowledge acquisition, advisory, consultancy and knowledge translation services from research and innovation intermediaries - public and/or private. However, we think their characteristics demand further recognition of the interactive and often innovative communication networks by means of which these cluster incumbents interact globally. This is because they are set within a worldwide system that can be conceptualised as an exemplar of the well-known construct known as an ‘assemblage’ (Deleuze and Guattari, 2004a). Unlike more recent treatments from De Landa (2019) and others, we try to concentrate on the motive power of the ‘agentic’ impulses of ‘desire’ that motivate human action (e.g. regarding ‘God, Gold or Glory’ as commonly-rehearsed motivators for colonialism of various kinds). It has been more common to use ‘assemblage theory’ to analyse the interlocking ‘machinic’ elements of complex systems like power networks or laboratory interactions. To unlock the mysteries of system interlocking in our selected tax havens, which comprise Wilmington, Delaware (US), Ireland (EU) and Gibraltar (former EU, now British Overseas Territory) – post-Brexit - occupying a ‘quantum’ space ‘in which both the colonial and post-colonial find expression’ (Perera, 2021). Methodologically, we seek ‘pattern recognition’ to identify the lineaments that explain these clusters and the ‘agentic’ actors that motivate them.
Humanistic place leadership, cultural enhancement, and change in industrial districts
Authors: Bellandi Marco
Published: October 2024

Drawing inspiration from the works of Fiorenza Belussi on multiple paths of development in local productive systems, the essay contributes to the ongoing debate on factors facilitating such transformations, focusing primarily on industrial districts (IDs) as open learning systems. With speciﬁc reference to the Italian context, this paper recalls the delicate balance between socio-cultural and economic elements within IDs transitioning towards new paths of development, crucial for facing the current technological and societal challenges. e essay proposes to look at the possible diﬀusion of humanistic management (HM) and cultural enhancement of economic strategies, as new triggering factors against lock-in conditions and tendencies toward degradation during phases of ID transformation. HM prioritizes the well-being of individuals and ethical decision-making, aligning with a broader societal purpose. Cultural enhancement, rooted in a common heritage, supports place identity, and suggests bases for multiple specializations. e convergence of HM and cultural enhancement within IDs may oﬀer to renewed place-leaderships levers for strategies of transition pointing to sustainable paths that align with broader societal goals in an era of disrupting challenges.
From fashion to sustainability

Sustainability issues are increasingly inﬂuencing ﬁrms’ decision making, leading to the creation of new business models for ﬁnding solutions to environmental and societal challenges. is work aims to explore what is the role played by industrial districts in ﬁrms’ orientation towards sustainability. It implements a Propensity Score Matching technique on a novel datatabase with information on 1300 Italian fashion ﬁrms. eir sustainability orientation is measured using the Quantitas Intelligent Business Analyzer (QIBA), an original Natural Language Processing-based data mining technique, which allows scraping ﬁrms' websites and analyzing their content adopting a Term Frequency–Inverse Document Frequency weighting scheme. Findings suggest the existence of a sustainability-driven industrial district eﬀect, i.e. a positive association between the sustainability orientation of fashion ﬁrms and their localization in industrial districts.

, which is compatible with a circular orbit given our data. Using the obliquity constraints, we show that they join a growing group of hot and low-density Neptunes on polar orbits. We use long-term radial velocities to rule out companions with masses ∼0.3–50 M
J within ∼10 au. We show that the orbital architectures of the two Neptunes can be explained with high-eccentricity migration from ≳2 au driven by an unseen distant companion. If HATS-38 b has no residual eccentricity, its polar and circular orbit can also be consistent with a primordial misalignment. Finally, we perform a hierarchical Bayesian modeling of the true obliquity distribution of Neptunes and find suggestive evidence for a higher preponderance of polar orbits for hot Neptunes compared to Jupiters. However, we note that the exact distribution is sensitive to the choice of priors, highlighting the need for additional obliquity measurements of Neptunes to robustly compare the hot Neptune obliquity distribution to that of Jupiters.
The Metallicity Dependence of PAH Emission in Galaxies. I. Insights from Deep Radial Spitzer Spectroscopy

We use deep Spitzer mid-infrared spectroscopic maps of radial strips across three nearby galaxies with well-studied metallicity gradients (M101, NGC 628, and NGC 2403) to explore the physical origins of the observed deficit of polycyclic aromatic hydrocarbons (PAHs) at subsolar metallicity (i.e., the PAH–metallicity relation or PZR). These maps allow us to trace the evolution of all PAH features from 5–18 μm as metallicity decreases continuously from solar (Z
⊙) to 0.2 Z
⊙. The total PAH-to-dust luminosity ratio remains relatively constant until reaching a threshold of ∼ 2/3 Z
⊙, below which it declines smoothly but rapidly. The PZR has been attributed to preferential destruction of the smallest grains in the hard radiation environments found at low metallicity. In this scenario, a decrease in emission from the shortest-wavelength PAH features is expected. In contrast, we find a steep decline in long-wavelength power below Z
⊙, especially in the 17 μm feature, with the shorter-wavelength PAH bands carrying an increasingly large fraction of power at low metallicity. We use newly developed grain models to reproduce the observed PZR trends, including these variations in fractional PAH feature strengths. The model that best reproduces the data employs an evolving grain size distribution that shifts to smaller sizes as metallicity declines. We interpret this as a result of inhibited grain growth at low metallicity, suggesting continuous replenishment in the interstellar medium is the dominant process shaping the PAH grain population in galaxies.
Two Million Contributions From Citizen Scientists Accelerate the Digitization of the Berlin Herbarium
Authors: Güntsch Anton , Röpert Dominik , Rabe Katharina , Paule Juraj
Published: October 2024

In 2016, the Botanic Garden Berlin decided to translate into German, the citizen science platform "Les Herbonautes" (Rouhan et al. 2016, developed at the Natural History Museum in Paris) and to integrate it into the digitization workflows of Herbarium Berolinense. "Die Herbonauten" is a web-based platform on which citizen scientists can contribute to the transcription of digital herbarium specimens and their labels.

Using a quiz module, users first learn about the various information elements on herbarium labels and their correct semantic assignment and recording. The actual data entry then takes place in so-called "missions," in which herbarium specimens are compiled, e.g., to support work on specific scientific questions. In addition to data entry, there is a forum in which users can discuss problems and their solutions, for example if there is disagreement about the correct transcription of a text element. The forum is moderated by scientific staff of the Herbarium Berlin, who provide support particularly when the knowledge of the collection curators is needed to solve problems.

In the course of numerous missions, the knowledge about transcriptions of herbarium specimens was summarized and structured in an evolving and extensive wiki system in German. This wiki has developed into a unique and valuable knowledge base for which an English translation is planned for use by an international audience.

To date, 640 registered Herbonauten have made around two million data contributions. Citizen science has thus become an indispensable component of the herbarium's information management. For the further development of the platform, we are experimenting, among other things, with expanding the scope, e.g., to include the recording of character data, and with combining citizen science approaches with AI-based transcription algorithms. In the context of the EU project, Transforming European Taxonomy through Training, Research and Innovations (TETTRIs), the Herbonauten carry out joint missions with other citizen science platforms, where selected specimens are processed by communities that are particularly qualified, for example because they have the necessary knowledge of languages or local geography.

One of the main factors in the capacity of passive autocatalytic recombiners (PARs) is its productivity or the hydrogen removal rate. In this work it was demonstrated that regardless of the type of a recombiner, the hydrogen removal rate is mostly determined by the catalytic surface area and the molar density of hydrogen at the inlet. It means that the performance of a recombiner should obey geometric and physical scalability.

Geometric scalability is characterized by the retention of the specific (per unit area of the catalytic surface) hydrogen removal rate with increasing the size of the recombiner by increasing the inlet section while maintaining the height and design of the catalytic unit.

Physical scalability is characterized by maintaining the hydrogen removal rate of the recombiner at a constant input molar density of hydrogen in an air-hydrogen environment while simultaneously changing the input temperature and pressure.

For a numerical demonstration of scalability, several calculations were performed with different initial hydrogen concentrations, external conditions and amounts of catalytic elements. It was shown that, regardless of the number of catalytic plates in the recombiner, the specific removal rate of hydrogen will remain unchanged and that under different external conditions (temperature, pressure), in case they correspond to the same inlet hydrogen density, the hydrogen removal rate does not change.
Intersectionality and Feminist Theory: A Framework for Understanding and Teaching Social Construct and Healthcare Policy
Authors: Dy Erin
Published: October 2024

The continuing nursing shortage throughout the United States has affected all aspects of the healthcare sector, particularly nursing leadership. As the Baby Boomer generation of nurses retires, the profession is primed to need more experience, advocacy, and leadership. This leaves a critical gap for leaders who identify with and are wise to the factors that influence the dynamic power relationships inherent to American history. As the country continues to become increasingly diverse, women and minorities in leadership continue to be underrepresented. In one of the most significant threats to women’s health, the recent overturning of the Supreme Court landmark case, Roe v. Wade, has highlighted the marginalization of women and people of color that is deeply embedded in the nation’s history. The lack of women and minorities in leadership positions in healthcare that has resulted from vast power imbalances, gender stereotyping, discrimination, and patriarchal structures must be addressed. Intersectionality theory offers a lens through which to understand these factors of power for all nurses. Nurse leaders can understand complex social constructs and be prepared to address power relationships that inform healthcare policy.

Women’s sexual and reproductive health (SRH) encompasses several topics, including but not limited to sexual expression, pregnancy, childbirth, contraception, and diseases of the reproductive system. The use of legal authority and power, as well as political influence, have long been factors used to regulate women’s SRH. In the United States (U.S.), examples of state and national legislation have been undertaken to impact SRH and medical treatment and decision-making related to SRH. Several national and international organizations engage in sexual and reproductive health rights (SRHR) activities. The activities of these national and international organizations in SRH often include policy formulation, data collection, monitoring, reporting, and other functions. While definitions of sexual and reproductive health rights vary, there are commonalities and core issues that can be identified. These include issues related to the LGBTQ population, immigration, and reproductive health rights among minoritized groups, which are leading topics wrapped around SRHR and of debate in recent history. This article aims to discuss sexual and reproductive health in promoting population health and societal well-being, recent policy decisions impacting SRH, and the role nurses play in shaping research, practice, and policies. For this paper, sexual and reproductive health rights (SRHR) are defined as an extension of human rights relating to an individual’s autonomy, sexuality, sexual expression, reproduction, and access to information and resources on SRH. SRHR also includes freedom from violence, discrimination, and mistreatment. While a comprehensive review of these areas is beyond this article's scope, historical and recent examples are illustrated.

Authors: Cook Cara , Chaudry Rosemary , Sattler Barbara
Published: October 2024

As the scientific evidence for human-caused climate change grows and awareness of the related health impacts increases, there is a need for nursing leadership in addressing climate change as a priority public health concern. The nursing role related to climate and health encompasses the nursing domains of research, education, practice, and policy/advocacy. Further, the Nursing Collaborative on Climate Change and Health - a partnership that includes the Alliance of Nurses for Healthy Environments, Climate for Health, and national nursing organizations - provides visible nursing leadership on climate change as a health imperative and creates momentum for solutions that nurses can engage in personally, in their communities and within the health sector.

Published: October 2024

Collaboration between academic centers and healthcare systems/practices has demonstrated improved outcomes, fostered innovation, and increased nursing research. Although evidence for their importance has been established, all too often these academic-practice partnerships (APP) encounter hurdles that limit success. Lack of time, poor communication, and unclear leadership endorsement are often barriers to effective APPs. Utilizing the challenges of the COVID-19 pandemic, a successful APP was developed based on the Interprofessional Education Collaborative (IPEC) competencies. The IPEC framework addressed needs related to the COVID-19 pandemic and became the foundation for many future endeavors between a large children’s healthcare system and a university school of nursing. This APP demonstrated the appropriate capacity and organizational structure to provide simultaneous benefits to multiple parties while improving systemwide healthcare outcomes. This article outlines the development and implementation processes, subsequent evaluation, and implications for practice related to this highly successful partnership.
