Is this scenery worth exploring? Insight into the visual encoding of navigating ants
Authors: Clement Leo , Schwarz Sebastian , Mahot-Castaing Blandine , Wystrach Antoine
Published: January 2025

Solitary foraging insects like desert ants rely heavily on vision for navigation. While ants can learn visual scenes, it is unclear what cues they use to decide if a scene is worth exploring at the first place. To investigate this, we recorded the motor behavior of Cataglyphis velox ants navigating in a virtual reality set-up (VR) and measured their lateral oscillations in response to various unfamiliar visual scenes under both closed-loop and open-loop conditions. In naturalistic-looking panorama, ants display regular oscillations as observed outdoors, allowing them to efficiently scan the scenery. Manipulations of the virtual environment revealed distinct functions served by dynamic and static cues. Dynamic cues, mainly rotational optic flow, regulated the amplitude of oscillations but not their regularity. Conversely, static cues had little impact on the amplitude but were essential for producing regular oscillations. Regularity of oscillations decreased in scenes with only horizontal, only vertical or no edges but was restored in scenes with both edge types together. The actual number of edges, the visual pattern heterogeneity across azimuths, the light intensity or the relative elevation of brighter regions did not affect oscillations. We conclude that ants use a simple but functional heuristic to determine if the visual world is worth exploring, relying on the presence of at least two different edge orientations in the scene.

Introduction Calcium hydroxide (Ca(OH)2) is the material of choice for pulp therapy. However, Ca(OH)2 has drawbacks such as toxicity, poor sealing, and tunnel defect formation. Alternative materials have been developed to provide more biocompatible materials with better dentin formation ability. The objective of this study was to evaluate the effect of composites containing gelatin (G), chitosan (CH), tetraethyl orthosilicate (TEOS), and Ca(OH)2, namely G-CH-TEOS-Ca (OH)2 (Extended data) on inflammation of the dental pulp (expression of COX-2, PGP 9.5, TNF-α, and neutrophil number). Materials and methods A total of 16 Wistar rat models of acute pulp injury were prepared and divided into two groups, treatment and control, 8 with each. In the treatment group, we applied a pulp-capping material using G-CH-TEOS-Ca (OH)2 and Ca(OH)2. On the 1st and 3rd days, rats were sacrificed. Tissue samples from 4 rats in each group were processed for histological preparation. COX-2, PGP 9.5, and TNF-α were observed using immunohistochemical (IHC) staining, and neutrophil numbers were observed using hematoxylin-eosin staining. Image analysis of COX-2, PGP 9.5, and TNF-α expression was performed using ImageJ software. Results The results showed a decrease in COX-2 expression, but not significantly while PGP 9.5 and TNF-α expression were significantly higher than those in the control group. Neutrophil numbers were lower in the treatment group than in the control group, but the difference was not statistically significant. Conclusion The G-CH-TEOS-Ca (OH)2 composite material may have potential as an exposed pulp medicament by reducing inflammation (COX-2 expression and number of neutrophils) and increasing the regeneration factor (TNF-α expression) and nerve (PGP 9.5 expression).
Punctator w Uniwersytecie Bolońskim w dobie studiów Kopernika
Authors: Sroka Stanisław
Published: January 2025

Mikołaj Kopernik studiował w Bolonii prawo kanoniczne i cywilne w latach 1496-1500. W artykule dokonano analizy zachowanych list nieobecności na zajęciach profesorów Uniwersytetu Bolońskiego podczas studiów Kopernika (obecność sprawdzał specjalny uniwersytecki urzędnik zwany punctator). Dodatkowo przeanalizowano opinie zawarte w brudnopisie wykazu zajęć (rotułu) na rok akademicki 1506/7. Kopernika wtedy już w Bolonii nie było (wyjechał z niej w 1500), ale byli to ci sami profesorowie, którzy wykładali w czasie jego bolońskich studiów. Analiza tych źródeł prowadzi do ostrożnej konkluzji, że studia prawnicze Mikołaja Kopernika w Bolonii mogły być dla niego rozczarowujące, a to z powodu z jednej strony niezbyt wybitnych postaci życia akademickiego wykładających na uniwersytetach prawniczych, zaś z drugiej niezbyt sumiennego podejścia do wykładów przez profesorów poprzez ich opuszczanie lub też niewielkie zainteresowanie samych żaków tymi wykładami. Z drugiej strony, na uniwersytecie artystów i medyków (gdzie m.in. wykładano astronomię) była grupa ponad przeciętnych wykładowców, których mógł słuchać młody torunianin, a których z pewnością brakowało na uniwersytetach prawniczych.

DETERMINANTS OF DIVIDEND POLICY– EVIDENCE FROM POLISH LISTED ENERGY COMPANIES
Authors: Witkowska Dorota , Kaźmierska-Jóźwiak Bogna , Kompa Krzysztof
Published: January 2025

In this paper we study the dividend policy of the energy sector companies listed on the Warsaw Stock Exchange. We test the relationship between dividend values and the firm’s financial performance and other firm’s characteristics (firm’s size, the State Treasury's ownership and diversity in the sub-sectors) employing pooled regression models. The novelty of the study lies in the fact that to measure firms’ financial performance we use a multidimensional vector synthetic measure of their financial efficiency (VSMD). The empirical data were collected from EMIS and Notoria Service. The study results show that the determinants of the dividend value are the size of a company and the VSMD (the bigger company and the more efficient, the higher dividend paid).
Walrasian Pricing for Combinatorial Markets with Compact-Bidding Languages: An Application to Truckload Transportation
Authors: Emadikhiav Mohsen , Day Robert
Published: January 2025

Combinatorial auctions offer several economic advantages but also face multiple technical challenges, including bid generation, the need to solve a combinatorial allocation problem, and determining reasonable prices. These challenges are even more pronounced in a combinatorial exchange, where bidders can simultaneously buy and sell combinations of goods. Motivated by truckload transportation markets, we explore new mechanisms for finding Walrasian equilibrium prices in combinatorial auctions and exchanges where bidders can use a compact-bidding language to express their potentially complex preferences. With the goal of improving economic efficiency and reducing the environmental impact of the trucking industry, we identify significant potential gains by developing a method for integrated allocation and price determination based on an industry-specific bidding language. We also demonstrate our proposed mechanism’s adaptability and flexibility by considering a number of practical constraints.
Guardians of integration? The Constitutional Court of Colombia and regionalism in the age of populism
Authors: Naranjo Cáceres Juan Zahir
Published: January 2025

This article examines how the Constitutional Court of Colombia (CCC) balances its role as guardian of the Colombian constitutional order while engaging in regional integration processes across Latin America. Through an analysis of constitutional theory, institutional development and the Colombian political context since 1991, the study explores how the Court interprets constitutional integration clauses while navigating increasing populist pressures. Moving beyond reductionist views of populism as mere demagoguery, the article analyses case studies of two contrasting populist leaders: conservative authoritarian Álvaro Uribe (2002–10) and progressive reformist Gustavo Petro (2022–26). By examining the theoretical foundations of constitutional guardianship and the institutional framework within which the Court operates, this analysis highlights the complex relationship between constitutional courts, regional integration and populist challenges in Latin America. The findings demonstrate how the CCC has developed judicial approaches that, while focused on domestic constitutional matters, contribute to broader regional judicial discourse. This theoretical exploration underscores how constitutional courts can shape regional integration processes while safeguarding their domestic institutional legitimacy. The Colombian experience offers valuable insights into the evolving role of constitutional courts in balancing national sovereignty with regional legal developments in an era of rising populism.

Authors: Yue Heng , Zhu Xiaobin , Ruyin Lyu , Gong Wei , Ma Xin
Published: January 2025

Mueller matrix polarimetry (MMP) effectively captures the polarization characteristics of biological tissues. This study established a subcutaneous osteosarcoma model in mice, utilizing MMP to analyze fresh tumor samples. We selected multilayer perceptron (MLP) and Kolmogorov-Arnold networks (KAN) as our classifiers and compared them based on nearby pixel attributes and single-pixel attributes, using MMP parameters as inputs. KAN generally performs better than MLP, suggesting its great potential for MMP datasets. Mueller matrix’s diagonal elements and the parameters Δ and D significantly contributed to tumor diagnosis. This research explores a non-invasive method for unfixed tumor identification, aiming for intraoperative rapid diagnosis.
Coherent modulation imaging of high signal-to-noise ratio and high reconstruction speed

Published: January 2025

Coherent modulation imaging (CMI) has become an effective tool for simultaneously detecting the modulus and phase of complex light fields. However, previously reported CMI methods suffered from low signal-to-noise ratios (SNR) and low convergence speeds. In this study, we propose a modified CMI method with high SNR and fast reconstruction speed. Both phase plate and diffraction patterns were split into nine units and then taken into reconstruction in 81 different combinations to suppress reconstruction noise. At the same time, since parallel reconstructions were carried out with these split units of reduced data volume, the reconstruction time was compressed from 40s to 2s. Experimental results suggest that this proposed method can make CMI more powerful for detecting laser beams, mechanical deformations, and biological samples.
Frequency-stabilized, three-frequency-shifted Nd:YAG laser at 372 nm for iron resonance fluorescence Doppler lidar

Published: January 2025

Single-mode, frequency-stabilized laser is a key component of a resonance fluorescence Doppler lidar, and the frequency of the laser emitting should be steadily locked on the resonance line of the metal atom. Here, a new Nd:YAG-based frequency-tripled source operating at 372 nm, which integrates an all-fiber-coupled seeder laser and an all-solid-state Nd:YAG laser, is developed for an iron resonance fluorescence Doppler lidar (Fe lidar). The saturation absorption spectrum of iodine near 558 nm is carried out for the first time, to our knowledge, to frequency stabilization, and the optical phase lock loop technique is used to realize the shift of seeder laser between three different frequencies. The seeder laser is injected into diode side-pumped Nd:YAG laser to generate a pulsed laser. An injection-seeded technique combined with an active cavity control technique (Ramp-fire) is applied to maintain resonance with the seeder laser and frequency stability of 864 kHz root mean square over 2 h is obtained. Laser power of about 1 W (∼16 mJ, 60 Hz) can be output after amplification and nonlinear frequency conversions. Lidar observation demonstrates that the developed source can be employed to profiling temperature and wind with high resolution and accuracy, and it can be a new choice for Fe lidar to observe atmospheric dynamics phenomena.

Human adenovirus type 36 (HAdV-D36) has been putatively linked to obesity in animals and has been associated with obesity in humans in some but not all studies. Despite extensive epidemiological research there is limited information about its receptor profile. We investigated the receptor portfolio of HAdV-D36 using a combined structural biology and virology approach. The HAdV-D36 fiber knob domain (FK), which mediates the primary attachment of many HAdVs to host cells, has a significantly elongated DG loop that alters known binding interfaces for established adenovirus receptors such as the coxsackie- and adenovirus receptor (CAR) and CD46. Our data suggest that HAdV-D36 attaches to host cells using a versatile receptor pool comprising sialic acid-containing glycans and CAR. Sialic acids are recognized at the same binding site used by other HAdVs of species D such as HAdV-D37. Using glycan microarrays, we demonstrate that HAdV-D36 displays a binding preference for glycans containing a rare sialic acid variant, 4-O,5-N-diacetylneuraminic acid, over the more common 5-N-acetylneuraminic acid. To date, this sialic acid variant has not been detected in humans, although it can be synthesized by various animal species, including a range of domestic and livestock animals. Taken together, our results indicate that HAdV-D36 has evolved to recognize a specialized set of primary attachment receptors that are different from known HAdV types and coincides with a unique host range and pathogenicity profile.
Song from the discarded: The multisensory shaping of a community corrido in the Oaxaca dump
Authors: Graves Kristen
Published: January 2025

This article examines a corrido, a Mexican folk song, crafted through the collaborative songwriting efforts of Los Pepenadores, a formally organized yet often disregarded workers’ union that laboured in the garbage dump of Oaxaca, Mexico. Situating this corrido within the community’s 42-year history of environmental interaction and their multisensory listening and sound-making practices reveals the organic development of their collaborative process. This community’s corrido serves as a testament to their history and a repository for their memories and stories. This article also addresses this corrido’s ongoing importance following the dump’s closure in 2022, as the community negotiates recording and sharing their song to honour and uphold their enduring connections. Drawing from two years of fieldwork, two decades of personal connection and engaging the fields of ethnomusicology, sound studies, discard studies and community music, I propose an interdisciplinary framework to examine how this corrido functions within this community, revealing its roles in self-representation, shared experience and inclusion. I argue that Los Pepenadores’ virtuosic, multisensory environmental engagement and strong communal ties, combined with the corrido genre’s deep cultural roots, produced a distinctive instance of multisensory songwriting. This collaboratively composed corrido stands as a poignant tribute to a proud community.
El sistema portuario de Gades y su área de influencia: aproximación a la organización fiscal y comercial en época romana a partir del poblamiento costero
Authors: Marfil Vázquez Francisco
Published: January 2025

El avance del conocimiento del ámbito costero bético está definiendo un panorama heterogéneo y variable generado a partir de la implantación del modelo productivo, comercial y fiscal romano. Las políticas territoriales y la inclusión de la península en las redes mercantiles trajeron consigo un profundo cambio en los modelos de explotación de los recursos naturales. El nuevo sistema se sustentó en una jerarquización del territorio y la creación de una estructura portuaria con los principales núcleos urbanos a la cabeza (Gades, Baelo Claudia, Iulia Traducta, Carteia, etc.), generándose en torno a éstos un poblamiento especializado en la producción y dependiente de los primeros. Los sucesivos estudios parecen apuntar a una serie de diferencias territoriales que permiten definir distintas áreas o distritos portuarios con características poblacionales y evolutivas propias.
En el caso del área del Estrecho de Gibraltar, la preponderancia tradicional de Gadir como referente comercial en las rutas atlánticas marcará en buena medida el desarrollo de toda su área de influencia durante el periodo romano. En este sentido, los enclaves costeros identificados en la actual provincia gaditana presentan unas características en cuanto a su desarrollo, patrones y ritmos de ocupación y producción que la diferencian de otras áreas béticas como pueden ser la actual costa onubense y malagueña, propiciando la identificación del litoral gaditano como un área o distrito portuario.

Published: January 2025

Information on the conservation of Astrocaryum aculeatum seeds can contribute to the sustainable management of this species, as commercial harvesting of its fruits is essentially extractivist. Thus, the objective of this study was to evaluate the germination and vigor of A. aculeatum seeds based on the storage conditions of diaspores (seeds with endocarp). A completely randomized experimental design was used, with a split-plot arrangement in time and four replications. Diaspores containing seeds with 21.1% moisture content were packaged and stored under the following conditions: a) permeable packaging in a natural environment (air temperature of 27.7 ± 1.5 °C and relative air humidity of 85.0 ± 11.9%); b) impermeable packaging in a natural environment; c) impermeable packaging in a cold chamber (18.0 ± 1.0 ºC and relative air humidity of 68.1 ± 6.2%). Seed moisture content, germination, dormancy, and mortality, percentage of seedling emergence, emergence speed index, and mean emergence time were evaluated after different storage periods (0, 2, 4, 6, and 10 months). Storing diaspores of A. aculeatum in impermeable packaging in a natural environment effectively preserve seed physiological quality for ten months. Contrastingly, storing diaspores in permeable packaging in a natural environment and in impermeable packaging in a cold chamber reduces seed physiological quality after two to three months of storage.

Es un libro de naturaleza jurídica porque propone los fundamentos sobre los que debe alzarse este nuevo derecho humano, a la vez que avanza cuál debería ser su contenido y los mecanismos de tutela, exponiendo las deficiencias actuales al respecto. Es por ello un libro que se enmarca en la disciplina de Filosofía del Derecho, ya que se circunscribe al método clásico de fundamentación, contenido y tutela cuando se refiere a la categoría de los derechos humanos. Pero también tiene este trabajo una vocación ambiental que es más novedosa. Es obvio que todo derecho humano está al servicio natural de la persona. Pero este derecho, por sus particularidades, incluye como sujeto protegido al medio natural en sí, siendo ésta una novedad radical. mediante este derecho el medio natural alcanza un cierto grado de dignidad, y esto obliga a replantear todo el aparato teórico en relación a los derechos humanos.

Published: January 2025

Aloe barbadensis Mill. is a medicinal plant of great importance, widely cultivated for its therapeutic properties. However, limited research has been conducted on the morphological diversity of Aloe vera germplasm in India. This study assessed the morphological diversity of 40 A. vera accessions collected from different agro-climatic regions in Tamil Nadu, India. Eight quantitative morphological descriptors were evaluated. Significant variations were observed for all the studied traits, indicating substantial morphological diversity among the accessions. Principal component analysis revealed that the first three principal components (PC’s) accounted for 72.90% of the total variation. Cluster analysis grouped the accessions into three main clusters based on morphological similarity. Associations were found between several traits, with correlation analysis showing significant positive correlations between plant size, leaf dimensions and yield-related traits. High broad-sense heritability estimates were observed for several characteristics, suggesting the potential for genetic improvement through selection. The findings highlight the morphological diversity in Tamil Nadu A. vera germplasm, which can be exploited for the genetic improvement and development of effective conservation strategies for this valuable medicinal plant. The morphological diversity observed in this study can be attributed to the diverse agro-climatic conditions and geographical locations from which the accessions were collected.

Finger millet is a traditional food crop that holds immense significance due to its versatility, climate resilience, and higher nutritional value. Finger millet growers face challenges due to poor soil properties and environmental conditions. To meet the growing demand, finger millet production must be substantially increased through suitable organic nutrient management practices. Hence, the present study was carried out to evaluate the effect of organic nutrient management on the productivity and profitability of finger millet. Field experiments were conducted during the Kharif seasons of 2019 and 2020 at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirappalli in a randomized block design with three replications. The treatments comprised of 100 and 125% N equivalent either through farmyard manure (FYM) or vermicompost or composted poultry manure, 50% N equivalent FYM + 50% N equivalent vermicompost, 50% N equivalent FYM + 50% N equivalent composted poultry manure, 50% N equivalent vermicompost + 50% N equivalent composted poultry manure and 100% recommended dose of fertilizer (RDF) (60: 30: 30 kg NPK/ha) + FYM (12.5 t/ha). Finger millet variety TRY 1 was used as test crop. The results revealed that the application of 100% RDF (60: 30: 30 kg NPK/ha) + FYM (12.5 t/ha) registered significantly higher growth, yield attributes and yield of finger millet than other treatments. However, it was comparable with 125% N equivalent vermicompost (3.8 t/ha) and 125% N equivalent composted poultry manure (3.5 t/ha). With regard to economics, application of 125% N equivalent composted poultry manure (3.5 t/ha) registered higher net return (Rs.41621/ha) and benefit cost ratio (BCR) (2.28) over other treatments. Hence, application of 125% N equivalent vermicompost (3.8 t/ha) or 125% N equivalent composted poultry manure (3.5 t/ha) could be recommended as organic nutrient management strategy for getting higher productivity and profitability of irrigated finger millet under sodic soil.
Evaluating the relationship between marijuana use, aggressive behaviors, and victimization: an epidemiological study in colombian adolescents
Authors: Scoppetta Orlando , Cardozo Francisco , Brown Eric C. , Morales Vanessa
Published: January 2025

Objectives

This study aimed to examine the relationship between marijuana use and aggression and victimization among Colombian adolescents. We aimed to clarify marijuana’s distinct role by comparing different categories of drug use and by considering the order of drug initiation.

Methods

We conducted a secondary analysis of nationally representative cross-sectional data collected from Colombian adolescents in 2016. The original sample included 80,018 students in Grades 7 to 11. Participants were categorized into marijuana-use groups – EXCLUSIVE (marijuana only), INITIAL (marijuana use before other drugs), and SUBSEQUENT (marijuana use following other drugs) – and non-marijuana-use groups – NON-DRUG (no use), ONE-DRUG (one other drug only), and MULTIPLE-DRUG (two or more other drugs).Aggressive behaviors (individual aggression, group aggression, harassment) and victimization were assessed based on self-reported involvement in the past 12 months. Logistic regression models examined associations between marijuana use patterns and these outcomes, controlling for sex, age, parental education, and grade repetition. For the SUBSEQUENT group, the total number of other drugs used was also controlled.

Results

Adolescents with no drug use had the lowest rates of all aggressive behaviors and victimization. As drug use increased, so did the prevalence of these outcomes, with MULTIPLE-DRUG users exhibiting the highest levels. Compared to NON-DRUG adolescents, each marijuana-use group (EXCLUSIVE, INITIAL, SUBSEQUENT) showed increased odds of some forms of aggression and victimization. For example, EXCLUSIVE users had higher odds of aggression compared to NON-DRUG users. However, the magnitude of these associations differed when comparing marijuana-use groups against each other and against ONE-DRUG and MULTIPLE-DRUG groups. INITIAL and SUBSEQUENT users often demonstrated greater odds of aggression than EXCLUSIVE users, suggesting that polydrug involvement and the sequence of drug initiation matter.

Conclusions

These findings underscore the importance of moving beyond binary classifications of marijuana use when examining aggression and victimization among adolescents. Marijuana use is associated with an increased risk of aggression and victimization, but other substance use patterns and the temporal order of drug initiation influence this relationship. Policymakers, educators, and clinicians should consider these when designing preventive interventions. Future research should employ longitudinal designs and incorporate additional contextual variables to further clarify the mechanisms linking marijuana use to aggression and victimization.

Published: January 2025

We report the experimental observation and characterization of Replica Symmetry Breaking (RSB) manifestation while analyzing the transverse intensity profile of laser pulses in filamentation experiments using sapphire crystal and distilled water, excited by a femtosecond laser centered at 800 nm. The RSB arises from the competition between self-focusing and plasma defocusing, subject to local fluctuations in the nonlinear refractive index generated by plasma via multiphoton excitation, which subsequently promotes frustration among modes. Our results confirm the existence of glassy-like photonic states not only in multifilamentation, as previously reported [W. Ettoumi, J. Kasparian, and J. Wolf, “Spin-glass model governs laser multiple filamentation,” Phys. Rev. Lett., vol. 115, no. 3, pp. 033902, 2015], but also in the generation of a single filament and in filamentation accompanied by conical emission. These findings improve the understanding of statistical nonlinear optics by establishing connections with magnetism and highlighting the glassy-like behavior of light in the context of ultrafast optical phenomena.
Network Structure and Collaborative Performance Among Environmental NGOs in China
Authors: Yang Yan , Cao Shuai , Yi Hongtao
Published: January 2025

Although the significance of NGO cooperation has been recognized in various studies, little is known about how NGOs in authoritarian states engage in collaboration, and few studies examine the outcomes of NGO collaboration from a network perspective. This article utilizes a questionnaire-based method to gather data on 103 environmental NGOs (ENGOs) in China. First, we confirm the existence of collaborative networks among NGOs in 19 provinces and municipalities in China. Then, informed by the social capital theory, we investigate the impact of bridging and bonding structures on network outcomes. The results show that bridging network structures can promote the efficiency and effectiveness of environmental NGOs in collaboration. In contrast, while bonding structures can also improve cooperative efficiency, they are not always effective. Overall, this study highlights the crucial role of central actors in collaborative networks, enriching existing literature and providing valuable insights for policymakers and NGO managers.
Kommen meine Kassenbeiträge bei meinem chronisch kranken Kind an?
Authors: Mülder Marje
Published: January 2025

In Deutschland leben ca. 2,2 Millionen chronisch erkrankte Kinder, die größtenteils über die Familienversicherung der gesetzlichen Krankenversicherung abgesichert sind. Die gesetzliche Krankenversicherung finanziert sich überwiegend über die Beiträge ihrer Mitglieder. Diese Beiträge sollen nach der gesetzlichen Konzeption für die Aufgaben der Krankenversicherung verwendet werden, sie dürfen also vor allem für die Krankenversorgung der gesetzlich versicherten Personen verwendet werden. Der Aufsatz zeigt die juristischen Vorgaben der Beitragsverwendung auf und erkundet zugleich die Vergütungssystematik sowohl in der ambulanten als auch in der stationären ärztlichen Versorgung. Denn auch diese muss den Vorgaben der gesetzlichen Krankenversicherung entsprechen. Da die Vergütungssystematik zum Teil auch Fehlanreize für eine andere Verwendung der Mittel setzt, zeigt der Aufsatz schließlich Wege zur Überprüfung der Beitragsverwendung durch die Versicherten auf.

The ego depletion effect—a sometimes-observed reduction in self-control performance following repeated self-control exertion—has been a topic of debate for over a decade. While a multitude of models have aimed to explain the effect, two prominent hypotheses are the focus of the current research: 1) the motivation shift hypothesis and 2) the compensatory effort hypothesis. So far, the mechanisms underlying both hypotheses (i.e., differences in exerted mental effort resulting from depletion and motivation) have not been tested and compared empirically. In a pre-registered experiment (N = 172), we manipulated depletion and motivation (presence of incentives) and physiologically assessed participants’ mental effort via systolic blood pressure (SBP) reactivity. Both hypotheses predict an interaction of depletion and motivation for mental effort, albeit with differing patterns. The results indicated that neither mental effort nor performance corresponded to either hypothesis. Instead, performance was consistent across all four conditions, with mental effort being predicted solely by the level of incentive. Both manipulation checks—self-reported depletion after the initial demand block and SBP reactivity during it—provided strong support for a successful depletion manipulation. Consequently, we conclude that these findings add to the growing body of evidence challenging the ego depletion effect empirically as well as its theoretical foundations.

The aim of research is to find factors that cause failure local government in providing access to basic types of services for hypertension sufferers according to SPM to all district residents, formulating appropriate regulations and public administration models and being able to mobilize collaboration among all pentahelix components to provide types of hypertension services according to the SPM, compiling and formulating models and strategies for collaborative collaborative governance, understand the role of facilitative leadership in collaborating across all pentahelix nodes , as well as creating breakthrough innovations in hypertension services. Research uses non-experimental qualitative methods with a case study approach, paying attention to the results of pre-eliminary studies , empirical facts and magnitude of public problems. Application of the pentahelix collaborative governance model has proven effective in increasing coverage of SPM for hypertension. Effective regulations consist of a regent's decision letter regarding the implementation of the pentahelix collaborative governance model, determining sub-district locus and a social contract between regent and all champions pentahelix. Cooperation model, roles and technical responsibilities of hypertension services for each pentahelix component at district, sub- district, village and RT/RW regional government levels, are regulated using a conceptual framework and business process standard for governance flow and reporting flow for implementation of pentahelix collaborative governance model. Facilitative and innovative leadership is the key to the success of Pentahelix collaboration in providing types of hypertension services that are easily accessible to all district residents.
