Opossums cleaning our cities: consumption of rodent carcasses in an urban reserve
Authors: Glebskiy Yury , Cano-Santana Zenon
Published: November 2023

Rodent carcasses are a source of food and a biological hazard that can commonly be found in natural and anthropic ecosystems. Therefore, this article aims to determine which organisms consume those carcasses in an urban reserve. For this, 53 rodent carcasses were placed in front of camera traps to record their consumers. The final destiny of 41 carcasses is known: 76 % were consumed by opossums (Didelphis virginiana) and 24 % by ringtails (Bassariscus astutus). Flies and ants attempted to take advantage of the carcasses but in all cases ended up losing the competition to mammals. Opossums are the most efficient carrion consumers, as they exhibit learning as to where the carcasses are located and are able to consume old carcasses (up to 10 days old). This suggests that mid-size mammals, especially opossums, are providing an important ecological and health service for both natural ecosystems and human populations by removing rodent carcasses that otherwise could become sources of infection.
Optical tuning of the terahertz response of black phosphorus quantum dots: effects of weak carrier confinement
Authors: Liu Xuan , Hou Lei , Ji Pengcheng , Wang Qiujin , Wu Min , Xiao Yiming , Xu Wen , Ding Lan
Published: November 2023

In contrast to few-layer black phosphorus (BP) with a relatively larger area, BP quantum dots (BP-QDs) are expected to have distinctive electromagnetic response and carrier behaviors, especially in low-frequency range such as in the THz regime. Herein, we experimentally investigate the THz properties of BP-QDs as well as the optical control of these properties. It is demonstrated that the effects of weak carrier confinement, which is associated with diffusive restoring current in each BP-QD, contribute significantly to the effective THz conductivity of BP-QDs. Instead, spectral features of discretely spaced energy levels as shown for many kinds of semiconductor QDs in UV-visible range are not observed in the THz regime. This indicates an insignificant contribution of strong quantum confinement here. Based on the modified Drude–Smith formula, we show that the optical excitation/pump of a CW laser can induce photogenerated carriers and enhance the effects of weak carrier confinement in BP-QDs. Thus, a nonlinear enhancement of THz absorption can be observed by increasing the power of the excitation laser. These results not only deepen our understanding of the fundamental physics of BP nanomaterials but also provide an alternative approach to realize active control of BP-based THz devices.
Niedrigzinspolitik und Sparkultur in Japan: Implikationen für die Wirtschaftspolitik
Authors: Schnabl Gunther , Sepp Tim
Published: November 2023

Das Papier untersucht die Veränderung der Sparkultur in Japan während mehr als 30 Jahren Niedrig-, Null- und Negativzinspolitik basierend auf einer Analyse der Allokationsfunktion von Zinsen und der Transformationsfunktion der Banken bei der Kreditvergabe. Es wird gezeigt, wie durch die anhaltend lockere Geldpolitik der Bank von Japan die Sparkultur in Japan grundlegend von einer hohen Haushaltssparquote zu einer sehr niedrigen Haushaltssparquote verändert wurde. Es werden aufbauend auf der theoretischen Literatur zu Sparmotiven Kanäle identifiziert, die das Haushalts- und Unternehmenssparen maßgeblich verändert und damit die Wachstumskräfte des Landes anhaltend geschwächt haben.
Eine Überprüfung der Informationsquellen für Inflationserwartungen
Authors: Kaiser Timo Pascal
Published: November 2023

Bisherige Befunde zeigen, dass Inflationserwartungen nicht vollständig der Hypothese Rationaler Erwartungen folgen. Statt kognitiver Begrenzungen sollen hier Mängel bei den Informationsquellen als Ursache beleuchtet werden. Die Ungewissheit über die wahren Zusammenhänge in einer Volkswirtschaft birgt für sich ein Informationsproblem. Informationsquellen können sich widersprechen, was eine Abwägung nötig macht. In einem Review wird der aktuelle Stand über die Anreize von Medien, privatwirtschaftlichen und staatlichen Prognoseinstituten sowie Zentralbanken berichtet, die zur Produktion verzerrter Informationen führen, welche die Inflationserwartung dadurch beeinflussen können. Aufgrund von Selektionseffekten sind die eigenen sowie Wahrnehmungen von Personen aus dem sozialen Umfeld keine zuverlässigen Quellen. Das Problem der verzerrten Informationsquellen für die Inflationserwartungen erweist sich als schwer zu lösen.
Institutioneller Wandel im Werk von Götz Briefs
Authors: Eissrich Daniel
Published: November 2023

Götz Briefs Konzept der Grenzmoral wird häufig zitiert, aber nur selten in einem umfassenden Kontext verwendet. Der folgende Beitrag legt dar, dass sich aus dem von Briefs dargestellten Prozess der Veränderung der Grenzmoral und der daraus resultierenden Bildung von Interessengruppen, Ansätze zu einer Theorie des institutionellen Wandels ergeben. Dabei erscheint Briefs kritische Betrachtung der institutionellen Entwicklung in den Industrienationen nicht nur von erstaunlicher Aktualität, sondern sein Werk bietet auch Anknüpfungspunkte zur modernen Theorie des institutionellen Wandels von Douglass C. North.
Den Fronsperger finde ich geistesgeschichtlich aufregend interessant
Authors: Klump Rainer , Pilz Lars
Published: November 2023

Alexander Rüstow und Walter Eucken tauschten sich zwischen 1941 und 1943 brieflich über das Buch „Von dem Lob deß Eigen Nutzen“ von Leonhard Fronsperger aus dem Jahre 1564 aus, in dem eigennütziges Handeln als Quelle allgemeinen Wohlstands gepriesen wird. Die zahlreichen von Rüstow und Eucken diskutierten Quellen und Bezüge des Buches, das bis heute weitgehend unbekannt geblieben ist, belegen seine Ausnahmestellung in der deutschsprachigen ökonomischen Literatur der frühen Neuzeit und zeigen, dass der Autor als früher Vorläufer von Bernhard Mandeville und Adam Smith angesehen werden kann. Weder Eucken noch Rüstow haben sich aber später noch einmal intensiver mit Fronsperger und seinem Werk beschäftigt; vermutlich erschien ihnen der dort vertretene Marktoptimismus für die Gegenwart unbrauchbar, da er keinen Blick für die Gefahren durch Monopolmacht, Lobbyismus und Interventionismus erkennen ließ. Eine erste englische Übersetzung des Buchs macht heute den Weg frei für seine Wiederentdeckung und eine angemessene internationale Würdigung.
Gustav Schmoller and the Idea of a Social Market Economy: A Precursor to Ordoliberalism?
Authors: Störring Matthias , Goldschmidt Nils
Published: November 2023

Despite the trenchantly formulated attempts of early ordoliberals to distance themselves from Gustav Schmoller, his research program can undoubtedly be identified as one of the numerous intellectual influences of their economic and sociopolitical ideas. In this article we dispel prominent misconceptions regarding Schmoller’s work and explain why the most fitting understanding of his approach today is contextual economics. We establish six characteristics of ordoliberalism that were already essential in Schmoller’s work, and which show great continuity in the tradition of German-speaking political economy. In this context, there is little more emblematic than the idea of the Social Market Economy as an “irenic formula”. We argue that the basic thought of social irenicism is also the essential leitmotif in Schmoller’s progressive conception of an economic order, which we call, by analogy with Müller-Armack, aSittliche Marktwirtschaft[Ethical Market Economy]. For a better and more reflective self-understanding, a modern economics of order [Ordnungsökonomik] would be well advised to develop a heightened awareness of its own intellectual roots.
Impfstoffmärkte, COVID-19 und gesundheitspolitische Maßnahmen in Deutschland: Ordnungsökonomische Anmerkungen
Authors: Kuchinke Björn A.
Published: November 2023

Die COVID-19-Pandemie ist das beherrschende Thema der letzten 18 Monate gewesen. Die Impfung gegen COVID-19 ist nach wissenschaftlicher Erkenntnis als der Ausweg anzusehen. Der Beitrag verdeutlicht, dass die mit COVID-19 zusammenhängende Impfstrategie in drei Phasen einzuteilen ist, wobei jeweils unterschiedliche Knappheitssituationen vorliegen. Bezüglich der ersten Phase (Knappheit Impfstoff) ist ordnungsökonomisch kein wirkliches Defizit auszumachen. Bei der Entwicklung, Zulassung und Produktion von COVID-19-Impfstoffen sind die Anreize für alle Beteiligten so gesetzt, dass möglichst viel sicherer Impfstoff in kürzester Zeit zur Verfügung steht. Die Politik hat diese Schritte überdies in merklichem Umfang monetär unterstützt. Ein wesentlich schnellerer Aufbau von Kapazitäten und eine signifikant höhere Impfstoffmenge ist im Betrachtungszeitraum auch durch andere Organisationsformen, wie etwa eine Art „Kriegswirtschaft“, nicht zu erwarten. Der Impfstoffmarkt funktioniert demzufolge, d. h. es ist kein Marktversagen zu erkennen. Eine ähnliche Einschätzung ist bezüglich der Phasen II (Knappheit Impfkapazität) und III (Knappheit Impfbereitschaft) nachzuvollziehen. Die Schaffung zusätzlicher Impfkapazitäten ist im Grunde nur durch eine Verpflichtung zur Verimpfung von COVID-19-Impfstoff aller niedergelassenen Ärzte und Krankhäuser zu erreichen. Ob dies notwendig ist oder wird, ist jedoch fraglich. Das größte Problem für eine möglichst schnelle Erreichung der Herdenimmunität ist die mangelnde Impfbereitschaft. Eine Möglichkeit wären in diesem Zusammenhang positive Anreize für noch nicht Geimpfte, wie etwa eine Impfprämie. Letzten Endes kann eine Herdenimmunität jedoch womöglich nur über eine generelle oder selektive Impfpflicht erreicht werden.

Authors: Schottmüller-Einwag Ute , Dilger Alexander
Published: November 2023

Dieser Beitrag untersucht die Entwicklung der Akzeptanz der Empfehlung G.13 Satz 1 des Deutschen Corporate Governance Kodex (in der Fassung vom 28. April 2022, vormals 4.2.3 Abs. 4 Satz 1), die für vorzeitige Vertragsbeendigungen von Vorstandsmitgliedern Abfindungsobergrenzen vorsieht. Die Abfindungshöhen der vorzeitig ausscheidenden Vorstandsmitglieder von DAX-Unternehmen im Verhältnis zu Jahresvergütung und Restvertragslaufzeit sind im Zeitraum 2015 bis 2019 signifikant niedriger als zwischen 2010 und 2014. Ein signifikanter Rückgang der Anzahl der Abfindungsfälle konnte nicht nachgewiesen werden. In den Erklärungen nach § 161 AktG der DAX-Unternehmen ist die Abweichungsquote bezüglich der untersuchten Empfehlung rückläufig, jedoch wird eine Überschreitung der empfohlenen Obergrenze in keinem der Fälle in der folgenden Erklärung erwähnt. Außerdem geht der Beitrag der Frage nach, ob verstärkt neue Formen großzügiger Zahlungen an ausscheidende Vorstandsmitglieder aufgetaucht sind.
Regulating Big Tech: From Competition Policy to Sector Regulation?
Authors: Budzinski Oliver , Mendelsohn Juliane
Published: November 2023

The European Commission has proposed a new regulatory tool to govern of digital markets. The Digital Markets Act (DMA) intents to limit the market behavior of so-called gatekeepers to ensure contestable and fair digital markets. We review the provisions of the DMA both from a legal and from an economic perspective. Notwithstanding a number of benefits, we identify several issues with the current proposal. When looking at the core provisions of the proposal from an economic perspective, a number of of contention arise: many of the provisions seem to be quite narrow in scope and it seems difficult to extrapolate more general rules from them; the economic harm of some of the provisions is both uncertain and in principle debatable; the alleged (self-executing; non self-executing) distinction between different types of obligations cannot be verified; and, in addition, Art. 5–7 DMA seem to contain three distinct regulatory instruments; last but not least, while the DMA seeks to control existing gatekeepers, the “tipping” of markets and the rise of further gatekeepers is not guaranteed by the proposed regulation, this in turn leads to a larger critical analysis of the gatekeeper as the DMA’s norm addressee. While the goals and nature of the DMA have gained in clarity throughout the legislative process, its scope remains somewhat obtuse. On the one hand it seems set on regulating gatekeepers as they exist today, on the other, it also aims to bring about systemic change in the digital single market. How it expects to achieve the latter is not entirely clear. On closer examination, the DMA also contains a complex enforcement regime that not only depends on the compliance of gatekeepers but may also forestall the envisioned speed and efficacy of the instrumment. In this light and by critically looking at the nature of ex ante and ex post measures in broader competition policy, we conclude that a reform of the competition policy regime would better suit the overalls aims of reining in big tech in future.
The Rule of Law at Risk: The Dark Side of the Digital Markets Act
Authors: Garnier Maya-Salomé
Published: November 2023

The Digital Markets Act is a new European Regulation which entered into force on October 2022. It will apply to “gatekeepers”, namely undertakings providing core platform services, with the aim of fostering “fairness” and “contestability” in the digital sector. If these objectives appear at first sight both relevant and legitimate, this paper sheds light on the dark side of this Regulation by arguing that it will undermine the Rule of Law. Indeed, for several reasons which will be discussed, the Digital Markets Act will impede or limit the respect of principles which are deeply rooted in the legal tradition of European countries. This leads to an important question: is the cure worse than the disease?
Ist die Forderung nach direkter Demokratie populistisch?
Authors: Hesse Nils
Published: November 2023

Ist die Forderung nach direkter Demokratie populistisch oder ist sie eine Antwort auf die Herausforderung des Populismus? Um diese Frage zu beantworten, unterscheidet der vorliegende Beitrag zwischen zwei Populismus-Typen, nämlich „genuinen“ und „nominellen“ Populisten. Während genuine Populisten insbesondere die demokratische Repräsentation und die politischen Kontrollmöglichkeiten der klassischen traditionalistischen, selbstbestimmten Mittelschicht verbessern möchten, berufen sich nominelle Populisten auf einen angeblich homogenen Volkswillen, der aber nur zur Rechtfertigung ihrer eigenen Position dient. Die Forderung nach mehr direkter Demokratie in Form von Referenden ist mit dem genuinen Populismus kompatibel, aber nicht mit dem nominellen Populismus. Schwerer mit dem genuinen Populismus zu vereinbaren ist das in der Constitutional Political Economy zentrale demokratische Legitimationskriterium der freiwilligen Zustimmung aller Bürger. Die etablierten Parteien können direktdemokratische Elemente dennoch nutzen, um der Entfremdung von Repräsentierten und Repräsentanten vorzubeugen und somit dem nominellen Populismus die Grundlage zu entziehen.
Effect of gamma irradiation on tensile, thermal and wettability properties of waste coffee grounds reinforced HDPE composites
Authors: Louahem M’sabah Ahmed Nabil , Bellili Nadira , Dairi Badrina , Ammouchi Nesrine
Published: November 2023

This study investigates the impact of gamma irradiation on the properties of waste coffee grounds (WCG)/high-density polyethylene (HDPE) composites. The composites were manufactured with 20 wt% of unirradiated and irradiated WCG at 10 and 20 kGy doses of gamma radiation. Through the utilization of a two-roll mill followed by a hydraulic press. The properties of the composites were analyzed through several methods, including contact angle measurements, hardness and tensile tests, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), in order to understand the influence of gamma irradiation. The addition of WCG decreased the tensile strength of the composite. However, gamma irradiation at 10 and 20 kGy led to substantial improvements in thermal stability and tensile strength compared to unirradiated samples. The SEM images showed the alterations within the fiber-matrix interface that corroborated the enhanced tensile properties after the treatment. While FTIR spectra confirmed the changes in functional groups of WCG caused by the irradiation process, gamma irradiation treatment not only increases fiber-matrix adhesion but also significantly improves the water resistance of the composites. These results suggest that gamma irradiation can be used for the modification of agro-waste materials as a beneficial process and the fabrication of high-performance, environmentally friendly composites.

Published: November 2023

The synthesis of an efficient adsorbent to remove chromium ions from water is challenging. Therefore, in this study, a new nanomagnet composite (Fe3O4/biochar/ZIF-8) was synthesized by a one-pot hydrothermal method using a metal–organic framework (MOF, ZIF-8) as a sacrificial template, citrus peels as a source of biochar, and iron oxide nanoparticles for magnetization. The synthesized nanocomposite showed a high efficiency toward the adsorption of Cr(vi) ions. The adsorption study showed that the experimental data were well-described using the Langmuir isotherm model and pseudo-second-order model. According to the Langmuir model, the adsorption capacities toward Cr(vi) adsorption were 77 and 125 mg·g−1 for Fe3O4/biochar and Fe3O4/biochar/ZIF-8, respectively, indicating the role of MOF in improving the adsorption performance. The Fe3O4/biochar/ZIF-8 showed an excellent adsorption performance in the presence of coexisting ions at a wide pH range using different eluents to study reusability up to five successive cycles. We can conclude from this study that this nanoadsorbent is a promising material for removing pollutants from environmental water samples.

Authors: Rüdiger Jens , Wegener Linda
Published: November 2023

Visiting wine tourism events is an attractive part of a trip for holidaymakers and day visitors. Thus, wine tourism is an important niche market for Germany with its 13 wine regions. Experiences play an increasingly important role in the consumption of tourism services. Therefore, it is also important to organize wine tourism events in an experience-oriented way. The present research design uses the KANO model to determine the requirements for experience staging at wine events from the customer’s point of view. The aim of the study is to provide wineries and other wine tourism providers with recommendations for experience staging in order to increase the attractiveness of the events and to improve the economic success.
A doubly mononuclear cobalt(II) complex constructed with azide anions and a new coordination mode of the 2-(2-pyridylmethylamino) ethanesulfonic acid ligands: structure, conformation comparison and Hirshfeld surface analysis
Authors: Chen Shu-Hui , Song Hai-Tao , Xu Xia
Published: November 2023

A doubly mononuclear cobalt(II) complex [Co(Hpmt)2(N3)2]2 (1) (Hpmt = 2-(2-pyridylmethylamino)ethanesulfonic acid; N3 = azide anion) has been synthesized and structurally characterized. Single-crystal X-ray diffraction analysis showed that 1 has crystallized in orthorhombic crystal system, Cmc21 space group. In the two independent and identical complexes, the cobalt(II) centers are both hexa-coordinated in distorted CoN6 octahedrons. The reduced Schiff base ligand Hpmt displayed a new coordination mode of bidentate chelate (κ
2-N,N′). The careful comparisons between Hpmt upon coordination and as free acid form demonstrated that the conformation flexibility might be responsible for its multiple coordination modes. The N–H⋯O and C–H⋯N hydrogen bonds constructed the 3D network, and this mainly agreed with the Hirshfeld surface analysis results.
Electrical and magnetic properties of MF/CuAl nanocomposites
Authors: Roumaih Khaled
Published: November 2023

This study investigated the effects of CuAl2O4 (CuAl) on four types of spinel ferrites: CoFe2O4 (CoF), NiFe2O4 (NiF), MgFe2O4 (MgF), and ZnFe2O4 (ZnF) with regards to their electrical characteristics and microscopic magnetic behavior. According to the Seebeck coefficient (φ), the nanocomposites have a mixture of positive and negative charge carriers, except for CoF/CuAl, which has a positive charge carrier only. Depending on the temperature, the
DC
conductivity of all MF/CuAl nanocomposites has a conductor and semiconductor behavior. The dielectric properties were studied at different frequencies (100–10^8 Hz) and temperatures (300–673 K). The results demonstrated how temperature and frequency affect
AC
operating mechanisms. The high values of dielectric loss for all nanocomposites confirm their applicability in high-frequency microwave devices. The impedance study revealed that the equivalent circuit for all MF/CuAl nanocomposites is a mixture of R, L, and C. Temperature-magnetization graphs were obtained for all nanocomposites, indicating ferrimagnetic behavior except ZnF/CuAl. The magnetic transition temperature (T
Cm), the Curie–Weiss constant (θ
CW), and the effective magnetic moments (μ
eff) for all nanocomposites were determined. The MF/CuAl samples were analyzed using ESR spectroscopy at room temperature. The spectra were distorted but remained distinct, potent, and sweeping. The g-factor values deviate from the free electron, which suggests that the Fe3+–O–Fe3+ superexchange interaction has changed. In addition, the interaction effect between MF and CuAl is discussed.

Die Fertigung kundenindividueller elektronischer Bauteile ist durch volatile Losgrößen und heterogene Automatisierungsgrade geprägt. Trotz verfügbarer Assistenzsysteme können zeitbezogene Abweichungen oft erst mit hohem Aufwand in der Produktionsleitung identifiziert und geeignete Maßnahmen verzögert eingeleitet werden. Um eine proaktive Steuerung auf Feldebene zu realisieren, bedarf es einer teilautomatisierten Lösung. Process Mining stellt einen datenbasierten Ansatz dar, um den organisatorischen und zeitlichen Produktionsablauf aufzudecken. Anhand prädiktiver Ergebnisse im operativen Betrieb können somit geeignete Maßnahmen bereitgestellt werden. In diesem Beitrag wird ein anwendungsorientierter Ansatz zur vorhersagenden Prozesssteuerung von Fertigungsabweichungen unter Einsatz von Process Mining vorgestellt.

Contributions for teaching religiosity/spirituality in undergraduate nursing programs: a qualitative study with Brazilian nurses
Authors: Cunha Vivian Fukumasu da , Coimbra Susana , Fontaine Anne Marie , Neubern Maurício da Silva , Scorsolini-Comin Fabio
Published: November 2023

Objective: to identify and collect recommendations for teaching religiosity/spirituality in undergraduate Nursing courses of nurses working in a Hospital. Method: this is a qualitative study, with 34 nurses interviewed. The research corpus was fully transcribed and submitted to content analysis. Results: the religiosity/spirituality theme was absent in the graduation of most of professionals. They mentioned the restricted preparation to deal with human issues and for being a dimension that offers a resource to face the challenges of the daily life of the profession. What mitigated this gap was that some professionals have their own religious/spiritual beliefs, which have often guided how this religious/spiritual support is provided in health care. Conclusions: participants suggest the presence of religiosity/spirituality teaching in nursing graduation effectively and practically, not only theoretically reinforce its importance. Taking religiosity/spirituality content to undergraduate courses can be sensitive to the holistic needs of patients/users and even the professionals themselves.
Diabetes Mellitus and Pancreatic Cancer: Investigation of Causal Pathways Through Mendelian Randomization Analysis
Authors: Deng Zuliang , Long Wenxing , Duan Hanping , Hui Xie , Tao Tan
Published: November 2023

Objective:This study was aimed at investigating the association between diabetes mellitus and susceptibility to pancreatic cancer by using Mendelian randomization (MR) methods and an extensive human genome-wide association study (GWAS) dataset.

Methods:The publicly accessible MR Base database was used to obtain the complete genome, relevant research findings, and summary data pertaining to diabetes mellitus and pancreatic cancer. Genetic variables, specifically single-nucleotide polymorphisms closely associated with diabetes mellitus, were selected for analysis. Four methods—inverse variance weighted (IVW) analysis, weighted median analysis, weighted mode, and MR-Egger regression—were used. Statistical analysis was conducted to explore the potential association between diabetes mellitus and susceptibility to pancreatic cancer.

Results:The results of the IVW analysis (OR = 11.56519319, 95% CI 1.275068624–104.8992116, P = 0.0296) indicated a significant causal relationship between diabetes and elevated pancreatitis risk. Furthermore, the absence of horizontal pleiotropic effects (Egger intercept = 0.29, P = 0.384) and heterogeneity (P = 0.126) suggested that the observed association was not influenced by confounding factors. Sensitivity analysis and other statistical methods also supported the conclusion that genetic pleiotropy did not introduce bias to the findings.

Conclusion:A causal relationship exists between diabetes mellitus and the occurrence of pancreatic cancer. People with diabetes mellitus are at high risk of pancreatic cancer and should receive early screening. The IGF signaling pathway may be a key mediator of the effects of diabetes on pancreatic cancer pathogenesis.

Kisspeptin upregulates β-cell serotonin production during pregnancy
Authors: Hill Thomas G , Smith Lorna I F , Ruz-Maldonado Inmaculada , Jones Peter M , Bowe James E
Published: November 2023

During pregnancy the maternal pancreatic islets of Langerhans undergo adaptive changes to compensate for gestational insulin resistance. The lactogenic hormones are well established to play a key role in regulating the islet adaptation to pregnancy, and one of the mechanisms through which they act is through upregulating β-cell serotonin production. During pregnancy islet serotonin levels are significantly elevated, where it is released from the β-cells to drive the adaptive response through paracrine and autocrine effects. We have previously shown that placental kisspeptin (KP) also plays a role in promoting the elevated insulin secretion and β-cell proliferation observed during pregnancy, although the precise mechanisms involved are unclear. In the present study we investigated the effects of KP on expression of pro-proliferative genes and serotonin biosynthesis within rodent islets. Whilst KP had limited effect on pro-proliferative gene expression at the time points tested, KP did significantly stimulate expression of the serotonin biosynthesis enzyme Tph-1. Furthermore, the islets of pregnant β-cell-specific GPR54 knockdown mice were found to contain significantly fewer serotonin-positive β-cells when compared to pregnant controls. Our previous studies suggested that reduced placental kisspeptin production, with consequent impaired kisspeptin-dependent β-cell compensation, may be a factor in the development of GDM in humans. These current data suggest that, similar to the lactogenic hormones, KP may also contribute to serotonin biosynthesis and subsequent islet signalling during pregnancy. Furthermore, upregulation of serotonin biosynthesis may represent a common mechanism through which multiple signals might influence the islet adaptation to pregnancy.
Polifonía de voces y los Otros-Silenciosos: una reflexión al antropocentrismo en la escuela

This paper presents part of the findings from the research project Sense of Respect for Life: Between the Silent-Other and the School, conducted as part of a master’s degree in education at the University of Cauca, Colombia. We explore the way in which humans have positioned themselves as 'superior beings' in their relationship with animals, referred to as the Silent Others by San Martín (2016). The objective was to understand the sense of respect for life attributed to the Silent-Other by students and teachers in the field of Natural Sciences in the eighth grade at the Gabriela Mistral School in the city of Popayán. We followed the phenomenological method based on Lester Embree's (2003) Reflective Analysis proposal, which allowed us to achieve the three phenomenological reductions: natural, eidetic, and transcendental. The study revealed an anthropocentric perspective of the Silent-Others, perceiving them as beings with human-like feelings and upon whom the selfhood of humans is projected.
Relación entre pobreza y conservación del capital natural desde los Medios de Vida Sustentables en Villaflores, Chiapas, México

Introduction]: Environmental degradation and poverty are a high priority on the agendas of international organizations for development and conservation. It is proposed that the relationship between poverty and conservation can be solved simultaneously, according to the Millennium Development Goals and, currently, the Sustainable Development Goals. [Objective]: This study aimed to describe the relationships existing between poverty and conservation of natural assets within livelihoods in the studied area. Additionally, it sought to investigate whether implementing conservation and sustainable rural development policies in a neoliberal context contributed to solving both problems. [Methodology]: A participatory-action-research was conducted as a case study. Participatory workshops were organized to diagnose sustainable livelihoods in the Sierra and Valleys micro-regions of the municipality of Villaflores, Chiapas, Mexico. [Results]: The influence of two prevailing rural development models in different periods on community livelihoods was observed: external forces that put pressure on livelihood strategies and have failed to lift communities out of poverty. In the case of the Valleys, this led to deforestation and degradation of natural assets, while in the Sierra, conservation was achieved, but communities are facing extreme poverty and high vulnerability. [Conclusions]: Policies and initiatives imposed in a top-down manner have led not only to environmental deterioration but also to the vulnerability and the process of precariousness of rural families.
canto da sereia da inovação na universidade comunitária

Novas demandas e funções são postas à educação superior na chamada sociedade do conhecimento. As universidades são instadas a mudar e inovar, visando contribuir para o crescimento econômico e a criação de riquezas. No âmbito da produção do conhecimento, um duplo desafio se desenha no contexto das universidades privadas sem fins lucrativos brasileiras: por um lado, exigências próprias do ingresso em um jogo de mercado por inovação, no sentido da pesquisa aplicada, útil ao setor produtivo, e, por outro, a manutenção da pesquisa desinteressada. O presente artigo analisa o caso das universidades comunitárias regionais do Rio Grande do Sul a partir da questão: quais as tendências na condução da pesquisa universitária diante de um cenário de novas exigências em termos de inovação e aproximação com o setor produtivo? Por meio de investigação de campo, realizada através de entrevistas com membros das universidades em estudo, seguida de dedução lógica entre os dados coletados e a literatura, argumenta-se que tais universidades, num contexto de crise decorrente do acirramento da concorrência mercantil, estão suscetíveis a caírem num canto da sereia, distanciando-se de um necessário nível de insulamento em direção a uma arriscada hiperporosidade com o mercado.
