Measuring of Social Sustainability Through Community Perceptions for Prima Certified Fruit Development in East Java
(2023-06-20)
The multidimensional perspective of ecological and social sustainable agriculture in the global agri-food system has resulted in the emergence of certification schemes as an important mode of governance, but there are still few agricultural actors in Indonesia who register for product certification and recertification. The purpose of this research is to analyze community perception in order to determine the development of Prima certified fruits in East Java. The sampling technique used quota sampling, with 5 people ...

Estimation of growth parameters in Brahman cattle from Mexico
(2023)
The objectives were to evaluate non-linear models (NLM) to define the growth curve of Brahman cattle in Mexico. The database was derived from weight development control, with live weight measurements (150,932 in females and 286,804 in males) taken in the interval from birth to 1095 days of age. Four NLM were evaluated: Brody, Bertalanffy, Gompertz and Logistic. The selection of the NLM with the best adjustment was made based on the Akaike and Bayesian information criteria. Growth parameters were generated: adult ...

Computing Ground States for Fermi-Bose Mixtures through Efficient Numerical Methods
(2023-05)
In this work, we will first review the Quantum Mechanics theory to derive the main equations. Next, we will analyze these equations by Functional Analysis methods to find conditions for existence, uniqueness, multiplicity, and other properties as positivity. Next, we will review and develop some numerical methods for solving the nonlinear Schrödinger equation, its time version, generalizations with rotational terms, and systems of NLSE (NLSS). We notice that the main problem to run numerical methods is the memory ...

Investigating the efficacy of common agricultural practices for the management of fall armyworm (Spodoptera frugiperda (J.E. Smith)) on cereal crops
(2023-07)
In Benin, the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is the most important polyphagous noctuid pest. This study aimed to assess the impact of agricultural practices on the abundance of this pest and determine whether its feeding preference and larval development differ among four cereal types. First, we conducted a descriptive survey of 80 farmers randomly selected for farm visits and oral interviews using a structured questionnaire to ascertain their preferred agricultural practices ...

„Jetzt kommt da so ne fremde Frau.“ Eine qualitative Analyse zur Beziehungsgestaltung in der ehrenamtlichen Betreuung von Menschen mit Demenz
(2023-06)
Angesichts der steigenden Demenzprävalenz gilt die Sicherstellung einer angemessenen Versorgung von Menschen mit Demenz als besondere Herausforderung unserer Zeit. Um die häusliche Sorge zu stärken und pflegende Angehörig zu entlasten, bietet die Pflegeversicherung Betreuungsleistungen als niedrigschwellige Unterstützung an. Nach § 45a SGB XI können Ehrenamtliche diese Leistung erbringen und Menschen mit Demenz stundenweise betreuen.
Die Dissertation stellt die bislang kaum erforschte soziale Beziehung zwischen den ...

Market-driven harvesting of non-timber forest products and the governance of communal forests in the south-east lowveld of Zimbabwe.
(2023-07)
Despite forests providing a wide range of important products and services for much of Zimbabwe’s population, natural forests are threatened by deforestation. The highest rates of deforestation occur in communal forests. Communal forest resources in Zimbabwe show evidence of increased degradation and signs of a breakdown of local institutions for resources management. These signs of a breakdown of local institutions are coupled with evidence of a lack of any emerging alternative institutions for conservation of forest ...

Hotspot 17 der biologischen Vielfalt - Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“
(2023)
Im Rahmen des Projektes „Schaf schafft Landschaft“ wurde von Oktober 2019 bis April 2022 eine Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“ (Hotspot 17) erarbeitet. Bei dieser Hotspotkonzeption wurde ein überregionaler, umsetzungsorientierter Ansatz verfolgt und die gesamte Region des Hotspot 17 in den Blick genommen, um möglichst umfassend die Themen mit besonderer naturschutzfachlicher Relevanz für den Erhalt der Biodiversität zu erkennen und mit ...

Situative Teams in Cooperative Autonomous Systems
(2023)
Distributed systems have been established in many areas of IT and will play an even more significant role in the future. Such systems are no longer limited to specific fields of application but interconnect many different domains. They encompass, e. g. Cloud Computing, Internet of Things, service robotics, and autonomous vehicles. The integrated sub-systems communicate in order to exchange information and, if necessary, perform tasks together. Moreover, the number of interconnected sub-systems is constantly growing. ...
