Building Bridges to European Integration: Albania and Kosovo's Joint Efforts in the Balkans

This study aims to look at the joint efforts of Albania and Kosovo in enhancing European integration within the Balkans. It tries to figure out, through an analysis of the joint programs and strategic partnerships, the extent to which these initiatives help them realize their shared goal of EU membership and regional stability. Prior Work: Previous scholarship has looked mostly into individual tracks on how to integrate into Europe by analyzing the political, economic, and social reforms undertaken by Albania and Kosovo separately. Other studies have tried to identify challenges and opportunities for the Western Balkans in this regard of EU integration. Yet little is known about cooperative work between Albania and Kosovo, and what it means for the wider regional context represents a gap in this literature. Key Findings: The two countries have managed, as shown by these findings, to build such a framework of cooperation together with dimensions being diplomatic, economic, and even cultural. Cross-border infrastructure projects, policy reforms, and joint diplomacy as well as collaboration in regional and international initiatives have played a bigger part in lifting up their prospects for integration. The paper shows how important it is for these two countries to ally strategically in tackling common challenges, like issues of political instability within their territories, fostering economic development programs, and social cohesion that make up the key tenets upon which EU membership is anchored.Value: This paper is therefore important in providing an insightful analysis into how synergistic cooperation between Albania and Kosovo can be used to enhance European integration prospects. It underscores the role bilateral cooperation can play in ensuring regional stability on the path to EU membership. The paper provides insight into how other aspiring member states from the Balkans can use cooperative strategies to inform the broader European integration agenda from a disadvantaged region. Future Longitudinal studies should be done to assess the impact that such joint initiatives by Albania and Kosovo could have on their EU integration trajectories over time. Comparative analyses with other regional Balkan partnerships could give a more nuanced knowledge of best practices and lessons learned. Moreover, investigating how international organizations and external stakeholders support these bilateral agreements will further make a lot of sense in the academic discussion on European integration in the region.

Value-behavior inconsistency is robust to promote cooperative behavior in structured populations.

The evolution of cooperation is a theme commonly studied in biology, psychology, sociology, and economics. Mechanisms that promote cooperative behavior in structured populations have been intensively studied. However, individuals' values, specifically, their opinions have been rarely taken into account so far. Inspired by cognition dissonance theory, we assume that individuals pay the cost of guiltiness if the behavior is defection but the opinion deviates from defection, and pay the cost of regret if the behavior is cooperation but the opinion deviates from cooperation. For all general stochastic evolutionary dynamics on arbitrary static networks with multiple opinions, we prove in the weak selection limit that: (i) value-behavior inconsistency cost promotes cooperative behavior if and only if the average cost of regret is less than that of guiltiness; (ii) individuals with value-behavior consistency are more abundant than that with value-behavior inconsistency. This is in contrast with other mechanisms that are at work for cooperation for one population structure but not others. Furthermore, it is also validated on an empirical network and for non-weak selection intensity. The value-behavior inconsistency is thus a robust mechanism to promote cooperative behavior in structured populations. Our results shed light on the importance of the co-evolutionary dynamics of opinion and behavior, which opens an avenue for cooperation.

(Un)cooperative Labor? Mining Cooperatives and the State in Bolivia

In 2019, Bolivian cooperative miners, once staunch allies of MAS and Evo Morales, helped inflame the crisis that toppled the Morales government. This paper explores the roots of the confounded, often explosive relationship between cooperative miners, nationalization, and MAS. Tracing the history of cooperative mining and its relationship to ore theft since the colonial period, this article shows how cooperative mining and salaried miners’ unions emerged as twin responses to the precarity of labor and production in the twentieth century. In the 1950s and 1960s, cooperative workers emerged as a shadow on the nationalized mining economy, competing for space and political influence with salaried workers. After the closure of COMIBOL in the late 1980s, cooperatives absorbed laid-off workers as well as migrants from the countryside and expanded into claims once belonging to state and union workers. When Morales reopened Bolivia’s national mining company in 2006 and sought to increase state participation in the mineral economy, he set the stage for a direct confrontation between the interests of cooperativistas, the vast majority of mineworkers at the time, and the state itself. This underacknowledged conflict of interests between different kinds of mineworkers has haunted MAS, culminating in the crisis of 2019 that drove Morales from power and from Bolivia.

Subak Lungatad in Preventing Land Conversion through the Revision of Awig – Awig

Subak is a community organization that specializes in regulating the rice field irrigation system used in rice cultivation in Bali, one of which is Subak Lungatad Yang in Peguyangan Kangin Village, North Denpaar. Subak Lungatad has a customary law norm called Awig-Awig. Awig-Awig is a customary law norm that is formulated and regulates the behavior pattern of community members in interacting in order to create order and peace, meaning that Awig-Awig grows and is formulated so that the life of the community in the customary village is not damaged. However, in the application of awig – awig Subak is also lived by the Balinese people as a concept of life, because it is a direct manifestation of the philosophy called Tri Hita Karana. There is a problem that arises in the awigs in Subak Lungatad is that they have not regulated and can anticipate changes in land use change in the subak Lungatad district Land use change in the last 1 year covering an area of 0.8 hectares, which is in Subak Lungatad, from the area of Subak 114 hectares. From this data, it can be described that land use change is still occurring. Pekaseh Subak Lungatad, I Made Maja, revealed that Subak Lungatad is part of the irrigation area of Kedewatan Pasedahan Yeh Lauh, Peguyangan Kangin Village, North Denpasar District. With a raw land area of 120 hectares, all of them are semi-irrigated. The subak land continues to experience pressure due to land conversion, there tends to be housing development. This condition is certainly really concerning for the future of rice fields and agriculture of the people of Denpasar. The participation of Krama Subak in preventing the conversion of agricultural land into housing can be done by including the rules in the awig-awig subak. Although the existing awig subak has not yet regulated it, it can be made in the form of a perarem or implementing rule of the awig- awig. The role of subak as a traditional organization in the field of water use at the farming level in indigenous peoples. The important role of the subak system is closely related to the strength of the subak itself, including the simplicity of the organizational structure, a cooperative work system and the implementation of the Tri Hita Karana philosophy. One of them is related to weakness which is also related to the lands in the subak lungakad area. The Awig Subak Lungatad that was made has not been regulated for a long time in anticipating changes in land use.

The Search for Paxlovid: Medication Acquisition as Anticipation Work After China's Zero-COVID Policy

In early December 2022, China's zero-COVID policy came to an end. For Chinese citizens, an imaginary of safety predicated on collective action and state care was replaced with a general focus on individualized responsibility for maintaining one's health. This expedited policy reversal had the unintended effect of infecting around 80% of China's population in one month, leading to a period of confusion, anxiety, and infection. One way of obtaining safety in a precarious time was to acquire medical resources. Through an online ethnographic investigation, we trace the acquisition of Paxlovid, an antiviral medication that had its distribution within China complicated by geopolitical tension and supply issues. By attending to the precarity of Chinese citizens at home and abroad, we show how Paxlovid was desired in both the present tense for the presently ill and in the future tense as an anticipatory form of safety. We use the analytical lens of anticipation work to unpack individual, collective, and state anticipatory practices supported by various social media platforms within and across borders. In doing so, we highlight moments of friction between and among various actors to argue that attending to affect, precarity, and practices in moments of conflict is critical to understanding the complexities of computer-supported cooperative work.

Indigenous Knowledge of Childhood Education among Konso, South West Ethiopia

The Konso are Cushitic language speaking communities of southwestern Ethiopia with distinct Indigenous knowledge of what they know and do, and what they have known and done for generations. Like other indigenous communities in this world, they have unique culture and way of life. The overall objective of this study understands the indigenous knowledge of childhood education among Konso which have the following specific objectives. Understanding the basic indigenous knowledge of children’s among Konso, understanding the basic institutions of childhood education among Konso, understanding the mechanisms of learning indigenous knowledge of childhood education in the study area and finally understanding the challenges that indigenous childhood education faces. The research applied qualitative research approach and ethnography as its enquiry mechanism. Primary data was collected by different ethnographic methods like key informant interview, focused group discussion and observation. The key informants are selected by purposive sampling technique from the Two Konso topographic areas of Karatte and Kenna and the data is analyzed by thematic interpretation with data triangulation technique. The findings of the study reveal that children’s among Konso acquire indigenous knowledge in two basic institutions i.e. Moora institution and Family institutions. As their teaching mechanisms, the families also the elders at Moora teach them in the form of poem and the other through observing different activities in and out of home. The highest challenge for ingenuous knowledge of childhood education among Konso is modern education, religious institution and westernization. Finally, the researchers recommend that ingenuous knowledge is a heritage for human society therefore it should be protected and kept away from diaper. Therefore, the responsibility is for all the communities, academicians culture and tourism bureau to work in cooperation to protect them.

How cooperative mindsets and course climate relate to the perceived impact of digital cooperation on learning in higher education

This article in the journal “Gruppe. Interaktion. Organisation. (GIO)” presents the results of a study examining one underlying mechanism of successful digital cooperation among students in higher education from a student perspective. We investigated whether and how students’ cooperative mindset and the climate in their university courses correlate with how they perceive the impact of digital cooperation on their learning outcomes. Data were collected using a questionnaire in different university courses at three universities, involving students from different study programmes and semesters. We conducted a mediation analysis that included students’ cooperative mindsets, the perception of the course climate, and the perception of the impact of digital cooperation on students’ learning outcomes. We found that students’ cooperative mindsets predicted their perception of the impact of digital cooperation on their learning. The cooperative mindset of students also predicted their perception of the course climate, which, in turn, predicted their perception of the impact of digital cooperation on their learning. Moreover, we found that the effect of students’ cooperative mindset on the perceived impact of digital cooperation on learning was mediated by the perception of the course climate. These findings suggest that highlighting the relevance of digital cooperation for learning outcomes can initiate a positive dynamic shaping students’ perceptions of their course climate and benefits of digital cooperation. Understanding these dynamics is crucial because cooperative group work in digital environments has become an integral part of teaching in higher education.

Federated learning-based wavelength demodulation system for multi-point distributed multi-peak FBG sensors.

Machine learning-based demodulation of multi-peak fiber Bragg grating (FBG) sensors has been extensively studied, demonstrating superior performance compared to conventional algorithms because it can neglect potential physical constraints. As the number of real-world monitoring points increases, the volume of fiber-optic sensing data grows exponentially. This necessitates aggregating data from various regions (e.g., via Wi-Fi), unlike traditional single-point monitoring, which challenges server storage capacity and communication efficiency. To address these issues, this paper proposes a federated learning (FL)-based framework for efficient wavelength demodulation of multi-peak FBGs in multipoint monitoring. Specifically, an arrayed waveguide grating (AWG) with multiplexing capability is employed at different monitoring points to convert spectral features into multi-channel transmission intensities, serving as training data for local models. Subsequently, the local model parameters, trained independently at each point, are uploaded to a central server to derive the optimal global model for demodulation across different monitoring points. The proposed demodulation framework is validated through stress demodulation experiments on multi-peak FBG sensors. Experimental results indicate strong multi-peak extraction performance with a demodulation error of ±0.64 pm. Additionally, the method demonstrates excellent applicability for generating high-precision global demodulation models through multi-node cooperative work under various scenarios.

Conducting Human Biology Research Using Invasive Clinical Samples: Methods, Strengths, and Limitations.

Invasive biological samples collected during clinical care represent a valuable yet underutilized source of information about human biology. However, the challenges of working with clinical personnel and the invasive nature of sample collection in biomedical studies can hinder the acquisition of sufficiently large sample sizes for robust statistical analyses. In addition, the incorporation of demographic data from participants is crucial for ensuring the inclusiveness of representative populations, identifying at-risk groups, and addressing healthcare disparities. Drawing on both research experiences and the existing literature, this article provides recommendations for researchers aiming to undertake efficient and impactful projects involving invasive human samples. The suggested strategies include: (1) establishing productive collaborations with clinicians; (2) optimizing sample quality through meticulous collection and handling procedures; and (3) strategically implementing a retrospective model to capitalize on existing invasive sample repositories. When established, cooperative work between clinical health care workers and biological anthropologists can yield insights into human biology that have the potential to improve human health and wellbeing.

Cybernic robot hand-arm that realizes cooperative work as a new hand-arm for people with a single upper-limb dysfunction.

A robot hand-arm that can perform various tasks with the unaffected arm could ease the daily lives of patients with a single upper-limb dysfunction. A smooth interaction between robot and patient is desirable since their other arm functions normally. If the robot can move in response to the user's intentions and cooperate with the unaffected arm, even without detailed operation, it can effectively assist with daily tasks. This study aims to propose and develop a cybernic robot hand-arm with the following features: 1) input of user intention via bioelectrical signals from the paralyzed arm, the unaffected arm's motion, and voice; 2) autonomous control of support movements; 3) a control system that integrates voluntary and autonomous control by combining 1) and 2) to thus allow smooth work support in cooperation with the unaffected arm, reflecting intention as a part of the body; and 4) a learning function to provide work support across various tasks in daily use. We confirmed the feasibility and usefulness of the proposed system through a pilot study involving three patients. The system learned to support new tasks by working with the user through an operating function that does not require the involvement of the unaffected arm. The system divides the support actions into movement phases and learns the phase-shift conditions from the sensor information about the user's intention. After learning, the system autonomously performs learned support actions through voluntary phase shifts based on input about the user's intention via bioelectrical signals, the unaffected arm's motion, and by voice, enabling smooth collaborative movement with the unaffected arm. Experiments with patients demonstrated that the system could learn and provide smooth work support in cooperation with the unaffected arm to successfully complete tasks they find difficult. Additionally, the questionnaire subjectively confirmed that cooperative work according to the user's intention was achieved and that work time was within a feasible range for daily life. Furthermore, it was observed that participants who used bioelectrical signals from their paralyzed arm perceived the system as part of their body. We thus confirmed the feasibility and usefulness of various cooperative task supports using the proposed method.

Barriers and facilitators to narrative nursing implementation for junior nurses: A qualitative study.

This study aimed to explore the experiences of barriers and facilitators to the implementation of narrative nursing by junior nurses. Participants were recruited using purposive sampling. Semi-structured interviews were conducted from October 2023 to February 2024. Data were thematically analyzed using the Colaizzi seven-step method. Five barriers and 3 facilitators to the implementation of narrative nursing by junior nurses emerged in the study. Relevant barriers include lack of practical skills related to narrative nursing, neglect of the concept of humanistic care, negative events, high workload for junior nurses, restricted implementation environment. The facilitators contain patients' and family members' trust, training related to knowledge and skills, as well as harmonious and cooperative working atmosphere. There is still room for improvement in the implementation of narrative nursing for junior nurses, and the systematic training of narrative nursing knowledge and skills should be enhanced; the medical humanistic environment should be optimized; and the psychological resilience of junior nurses should be improved, so as to encourage them to actively implement narrative nursing at the early stage of their careers, and to deepen the high-quality development of nursing humanism.

Can a work-readiness program mitigate unemployment scarring: the case of a co-operative education job market

ABSTRACT Using a two-year-long longitudinal dataset that follows co-operative education (co-op) students’ employment situations, this paper examines how unemployment in the first scheduled co-op work term is associated with un(der)employment in subsequent work terms. Drawing from unemployment scarring theory, the paper also investigates the role of a work-readiness intervention in reversing the potentially negative consequences of unemployment in the first scheduled co-op work term. The results suggest that unemployment in the first co-op work term is associated with underemployment in a subsequent work term. Compared to those who were employed in their first scheduled work term, students who were initially unemployed were just as likely to be employed in their second work term, but they got jobs later, were in jobs with lower seniority, and were paid less than expected. By the third scheduled work term, employment and underemployment were similar between all groups, except that initially employed students continued to earn more, suggesting an earnings penalty for initial unemployment that is consistent with unemployment scarring theory. Critically, participation in a work-readiness intervention reversed this narrative. Intervention participants did better than their unemployed peers in subsequent work terms, and their employment situation was more like that of the initially employed students.

Impact Of Relational Leadership on Effective Services of Church Volunteer Workers

The church thrives on the effective engagement of volunteer workers who give their time, money, and talents to promote the gospel through cooperative work with the church pastors and other church staff. Upon this assumption, the writers intend to promote relational leadership theory that can help pastors and other church staff engage and maximize their potential. In achieving this singular purpose, the writers explored the relational leadership theory and described who volunteers are in the church context. The research also discusses relational issues among volunteer church workers, while impacts that implementation of this theory could have on church workers were finally explained. The article reveals that relational leadership would help leaders prioritize interest in the church volunteer workers’ personal life; encourages formal and informal communication; inspires teamwork; and guides church volunteer workers toward achieving their job descriptions.

“You Are Not Here”: Coordinating Repair under Occupation

ABSTRACTThis research challenges dominant understandings of ubiquity, mobility, and connectivity and explores the limits ICTs through a qualitative study of a collaborative capacity‐building initiative to localize the repair of medical devices and equipment in the Gaza Strip. Dominant perceptions of ICT affordances rely upon taken‐for‐granted political, economic, and social systems that are neither universal nor guaranteed. Using a thickly descriptive, interpretivist approach, this research shows how ICTs are fundamentally insufficient to support team collaboration and meet the affective and material requisites of collaborative work under conditions of occupation. Digital networked technologies are particularly limited in their ability to create, simulate, and/or foster the interdependent conditions of presence, flow, and coordination required for cooperative work to succeed. Geopolitical borders and concomitant conditions of occupation continuously disrupt the logics of time and space between those living and working in Gaza and the “outside world”. Arbitrary and capricious fluctuations in tolerance, temporality, persistence, and permeability wrought by the ongoing siege of Gaza result in pernicious harms that are difficult or impossible to account for or correct with technical “solutions.”

Research on the Construction of Vocational School-Enterprise Cooperation Service Platform Based on Micro-services

With the deep integration of school-enterprise cooperation in higher vocational colleges, it is necessary to use micro-service technology for targeted analysis of various behavioral data involved in school-enterprise cooperation, and extract valuable information as the basis for guide school-enterprise cooperation work, to shift school-enterprise cooperation work from “business-driven” to more precise “data-driven” [1]. This article uses big data analysis as a means, adopts micro-service technology, and takes school-enterprise cooperation and industry education integration as the concept. Through the needs analysis of the college, the overall architecture of the school-enterprise cooperation service platform is designed. From business processes, big data analysis and intelligent visualization, the deep integration of school-enterprise joint training of teachers, school-enterprise collaborative teaching, and school-enterprise joint promotion of employment are achieved, and the expected effect is worth promoting.

Study on the Flexural Performance of Ultrahigh-Performance Concrete-Normal Concrete Composite Slabs.

In recent years, there have been an increasing number of examples of using ultrahigh-performance concrete (UHPC) as a pavement layer to form an ultrahigh-performance concrete-normal concrete (UHPC-NC) composite structure to improve the bearing capacity of bridges. In order to study the flexural performance of this kind of structure, this research studied the flexural performance of UHPC-NC composite slabs, with UHPC in the compression zone, using experiments, numerical simulation, and theoretical analysis. The results showed the following. Firstly, after the UHPC-NC interface had been chiseled, there was no obvious slip between the two materials during the test, and the composite plate was always subjected to synergistic stress. Secondly, the composite slabs in the compression zone of the UHPC were all subjected to bending failure, and the cooperative working performance of each part under the bending load was good, indicating that the composite slab had a unique failure mode and a high bearing capacity. Thirdly, increasing the thickness of the UHPC significantly improved the flexural capacity of the composite plate, and the maximum increase was about 15%. Increasing the reinforcement ratio of the tensile steel rebars also had an increasing effect, with a maximum increase of about 181%. Finally, the proposed formula for calculating the flexural capacity of composite slabs with UHPC in the compression zone could accurately predict the bearing capacity of said slabs. The calculated results were in good agreement with the experimental values, and the error was small.
