This paper extends the common pool resource (CPR) dilemma game (Budescu, Rapoport, and Suleiman 1995; Rapoport and Suleiman 1992) by relaxing the fixed, deterministic group size assumption. How group size uncertainty influences individual and group behavior and outcomes in CPR dilemmas is theoretically investigated. Group size uncertainty is not detrimental to collective interests; it reduces the probability of destroying a CPR. [ABSTRACT FROM AUTHOR]

Research Summary: The search for new resources is costly and difficult within the resource‐based view. Because search is costly, a common prescription is for firms to focus on their endowments—the resources they already possess. However, is there a way for firms to somehow find value amongst the "vast reservoirs" of external resources? We review existing forms of resource search and then suggest an alternative. Extending arguments from biology, we develop the idea of a firm‐specific search image and highlight how search images can reveal resources not obvious to others. The search image notion speaks to how firms might uniquely identify dormant resources, even in seemingly efficient factor markets. We conclude with a discussion of how our arguments pertain to the resource‐based view and the origins of resources. Managerial Summary: How do managers and entrepreneurs search, identify, and find assets and resources in relentlessly competitive markets? Existing arguments largely suggest that firms should not engage in costly and competitive "external" search—instead they should focus "inside," leveraging the endowments and resources they already possess. We argue that vast reservoirs of dormant resources are available, and that a particular form of external resource search offers a powerful alternative to the prescription to "look inside." Specifically, we highlight how a "search image" can enable entrepreneurs and managers to search and see resources and value that is not obvious to others. In particular, the search for a functional need—and solution to a formulated problem—can help firms recognize and find dormant resources and create value. [ABSTRACT FROM AUTHOR]

Common resource dilemmas (CRDs) and public good dilemmas (PGDs) are distinct types of social dilemmas, yet they model the same underlying conflict between the collective interest and one's self‐interest. Here, we study and interpret behavioral differences between these two main types of social dilemmas by applying a logic of appropriateness. In two experiments, we argue and demonstrate that CRDs, relative to PGDs, evoke higher levels of cooperation, because taking from collective property (in CRDs) is generally considered less appropriate than not giving from personal property (in PGDs). Importantly, these differential considerations of appropriateness are reflected not only in the willingness to cooperate but also in the willingness to punish and reward others' (non)cooperative behavior. Taken together, the findings reveal that CRDs and PGDs elicit different norms of appropriateness. [ABSTRACT FROM AUTHOR]

• Fishing conflict game assesses sustainable behavior concerning a common resource. • Six- to 11-year-olds played this game alone and in groups in different conditions. • More sustainable behavior with communication or when children played alone. • Limitation of withdrawal supported sustainable behavior. • Older children acted more sustainably. Acting ecologically sustainably and not exhausting natural resources is becoming more and more important. Sustainable behavior can be investigated within the conceptual frame of resource dilemmas, in which users share a common, slowly regenerating resource. A conflict emerges between maximizing one's own profit and maintaining the resource for all users. Although many studies have investigated adults' behavior in resource dilemmas, barely anything is known about how children deal with such situations and which factors affect their behavior. Due to their still developing cognitive and social skills as well as their self-control, they might act differently than adults. In the current study, 114 children aged 6 to 11 years played a fishing conflict game. We manipulated (a) whether children played alone or in groups, (b) whether withdrawal was limited or not, and (c) whether children were allowed to communicate within the groups or not. In addition, children's individual characteristics that were expected to be related to their sustainable behavior were assessed (i.e., delay of gratification, fairness concept, relatedness to nature, math grade, and age). Children's success in maintaining the resource strongly depended on the game context. Similar to adults, children acted more ecologically sustainably when they played alone, when the withdrawal was limited, and when communication was allowed. In addition, older children acted more sustainably than younger children. The results are discussed in the light of findings with adults and with regard to potential interventions that aim at enhancing children's sustainable behavior. [ABSTRACT FROM AUTHOR]

In this paper, we present a novel clustering-based resource allocation framework for downlink transmission in ultra-dense small cell networks. Specifically, we first model a combinatorial optimisation problem that jointly considers subchannel and power allocation and user traffic demand in terms of a large-scale network scenario. Unfortunately, the huge communication overhead and computational complexity make it challenging for traditional centralised/distributed solutions. To address this issue, we propose an interference-separation clustering-based scheme to divide the massive small cells into smaller groups with different priorities, which reduces the network scale. Different from the existing cluster construction scheme, the proposed clustering method effectively avoids the inter-cluster interference through coordination. Then, for a given cluster configuration, we formulate the distributed resource allocation problem as a local interaction game where the utility of each player comprises not only its own profits but also the interests of neighbours. We prove the existence of Nash equilibrium for the formulated game and design a hierarchical learning algorithm to achieve the Nash equilibrium, which only needs local information exchange. Finally, simulation results validate that the proposed solution outperforms some other existing approaches and is more suitable for large-scale networks. Copyright © 2016 John Wiley & Sons, Ltd.

In this paper, we study inter-operator spectrum sharing and intra-operator resource allocation in shared spectrum access communication systems and propose efficient dynamic solutions to address both inter-operator and intra-operator resource allocation optimization problems. For inter-operator spectrum sharing, we present two competent approaches, namely the subcarrier gain-based sharing and fragmentation-based sharing, which carry out fair and flexible allocation of the available shareable spectrum among the operators subject to certain well-defined sharing rules, traffic demands, and channel propagation characteristics. The subcarrier gain-based spectrum sharing scheme has been found to be more efficient in terms of achieved throughput. However, the fragmentation-based sharing is more attractive in terms of computational complexity. For intra-operator resource allocation, we consider resource allocation problem with users' dissimilar service requirements, where the operator supports users with delay constraint and non-delay constraint service requirements, simultaneously. This optimization problem is a mixed-integer non-linear programming problem and non-convex, which is computationally very expensive, and the complexity grows exponentially with the number of integer variables. We propose less-complex and efficient suboptimal solution based on formulating exact linearization, linear approximation, and convexification techniques for the non-linear and/or non-convex objective functions and constraints. Extensive simulation performance analysis has been carried out that validates the efficiency of the proposed solution. [ABSTRACT FROM AUTHOR]

How to exploit public non-renewable resources is a public goods dilemma. Individuals can choose to limit the depletion in order to use the resource for a longer time or consume more goods to benefit themselves. When the resource is used up, there is no benefit for the future generations any more, thus the evolutionary process ends. Here we investigate what mechanisms can extend the use of resources in the framework of evolutionary game theory under two updating rules based on imitation and aspiration, respectively. Compared with imitation process, aspiration dynamics may prolong the sustainable time of a public resource. [ABSTRACT FROM AUTHOR]

We used psychological methods to investigate how two prominent interventions, participatory decision making and enforcement, influence voluntary cooperation in a common-pool resource dilemma. Groups (N=40) harvested resources from a shared resource pool. Individuals in the Voted-Enforce condition voted on conservation rules and could use economic sanctions to enforce them. In other conditions, individuals could not vote (Imposed-Enforce condition), lacked enforcement (Voted condition), or both (Imposed condition). Cooperation was strongest in the Voted-Enforce condition (Phase 2). Moreover, these groups continued to cooperate voluntarily after enforcement was removed later in the experiment. Cooperation was weakest in the Imposed-Enforce condition and degraded after enforcement ceased. Thus, enforcement improved voluntary cooperation only when individuals voted. Perceptions of procedural justice, self-determination, and security were highest in the Voted- Enforced condition. These factors (legitimacy, security) increased voluntary cooperation by promoting rule acceptance and internalized motivation. Voted-Enforce participants also felt closer to one another (i.e., self-other merging), further contributing to their cooperation. Neither voting nor enforcement produced these sustained psychological conditions alone. Voting lacked security without enforcement (Voted condition), so the individuals who disliked the rule (i.e., the losing voters) pillaged the resource. Enforcement lacked legitimacy without voting (Imposed-Enforce condition), so it crowded out internal reasons for cooperation. Governance interventions should carefully promote security without stifling fundamental needs (e.g., procedural justice) or undermining internal motives for cooperation. [ABSTRACT FROM AUTHOR]

We test whether people with a relatively more intrinsic vs. extrinsic value orientation (RIEVO) are particularly likely to enact cooperative behavior in resource dilemmas when they are primed with relatedness goals. In Study 1, high RIEVO participants primed with relatedness exhibited more restrained fishing behavior in a resource dilemma than their unprimed counterparts or participants low in RIEVO. Study 2 replicated this effect and further showed that the prime must signal the possibility of satisfying a valued goal (relatedness satisfaction) in order to elicit the value-consistent behavior. We discuss these results in the context of recent process models of goal priming, and also discuss how these findings contribute to our understanding of cooperative behavior and the predictive power of value constructs more broadly.

We investigated how another person's emotions about resource allocation decisions influence observers' resource allocations by influencing the emotions that observers anticipate feeling if they were to act in the same way. Participants were exposed to an exemplar who made a fair or unfair division in an economic game and expressed pride or regret about this decision. Participants then made their own resource allocation decisions. Exemplar regret about acting fairly decreased the incidence of fair behavior (Studies 1A and IB). Likewise, exemplar regret about acting unfairly increased the incidence of fair behavior (Study 2). The effect of others' emotions on observers' behavior was mediated by the observers' anticipated emotions. We discuss our findings in light of the view that social appraisal and anticipated emotions are important tools for social learning and may contribute to the formation and maintenance of social norms about greed and fairness.

Traditionally, property rights have been seen as an efficient means of optimizing the allocation of common resources. The arrangement of property rights, however, has historically led to a number of social, economic and ecological issues. Herders living in China are currently exploring collective grazing partnerships as they seek to maintain balance between ecological protection and livelihood development in the process of grassland governance. For the purposes of this study, we conducted an in-depth analysis of the property rights dilemma, offering possible solutions for indigenous institutional arrangements as exemplified in six typical cases. We assert that (1) stakeholders should respect local culture by ensuring the participation of herders in policymaking, (2) the use of fences for the demarcation of property rights is ineffective and often serves as a catalyst for the destruction and degradation of grassland ecosystems, and (3) herders’ use of collective action techniques should be reinvented with the support of state policy.

Most common pool resource (CPR) dilemmas share two features: they evolve over time and they are managed under environmental uncertainties. We propose a stylized dynamic model that integrates these two dimensions. A distinguishing feature of our model is that the duration of the game is determined endogenously by the users' collective decisions. In the proposed model, if the resource stock level below which the irreversible event occurs is known in advance, then the optimal resource use coincides with a unique symmetric equilibrium that guarantees survival of the resource. As the uncertainty about the threshold level increases, resource use increases if users adopt decision strategies that quickly deplete the resource stock, but decreases if they adopt path strategies guaranteeing that the unknown threshold level is never exceeded. We show that under relatively high uncertainty about resource size, CPR users frequently implement decision strategies that terminate the game immediately. When this uncertainty is reduced, they maintain a positive resource level for longer durations. [ABSTRACT FROM AUTHOR]

Demand on multimedia content by consumers' handheld devices over wireless channels is on the increase. In view of the accelerated trend towards consumption of high quality video, power utilization by mobile devices is expected to excessively increase. Hence, it becomes equally important to advance more efficient power minimization techniques, in light of the short battery life in portable devices. However, power minimization algorithms that adopt consumers' perceptual quality of video have not received adequate research. This paper proposes a joint optimization of energy and quality requirements in a multiuser orthogonal frequencydivision multiplexing environment. A multi-objective optimization problem is formulated with the aim to identify bitrate allocations among users such that total power is minimized, and average quality is maximized. For this, a content-aware and energy-efficient resource allocation scheme (CaERAS) is proposed based on genetic and greedy algorithms. Simulation results show that CaERAS, as a lowcomplexity scheme, outperforms comparable methods in terms of efficiency and selectivity of suboptimal solutions. It is shown to acquire a suboptimal solution in as low as 0.0025 of the search space in previous methods. Also, a significant average saving of 85.66% in required energy is observed in broadcast transmission as opposed to unicast transmission. [ABSTRACT FROM AUTHOR]

A novel agent-based framework for modeling and simulating competitive and cooperative behavior under conflict is proposed. Formal definitions of Nash, general metarational, symmetric metarational, and sequential stability decision rules reflecting human behavior under conflict are presented in this paper. The definitions are inspired by the solution concepts of the graph model for conflict resolution and are conceived for implantation in the proposed agent-based modeling and simulation framework. With these decision rules, competitive and cooperative conflict dynamics are simulated for a theoretical common-pool resources dilemma. Moreover, policies can be tested for their effectiveness in avoiding or recouping from a tragedy of the commons. [ABSTRACT FROM AUTHOR]

The need for psychosocial counseling grows with the occupational, daily, interpersonal and social challenges which we are faced to. Its main objective is therefore to support methodological, reflexive, social and shaping skills of clients - including all levels of action in different social subsystems. The interactions between complex external conditions and individual decision-making and behaviors make it necessary counseling processes continues to systematize and operate in- terdisciplinary. Professional councelors are encouraged to develop comprehensible, realistic and effective problem solving strategies with clients. The article shows, how the counselor-client systemcanmeet the requirements of shaping and action competence. To clarify, the author presents a multi-functional intervention tool for practitioners: the behavior variogram VVg (VVg is the abbrevation for the german name of the behavior Variogram "Verhaltens-Variogramm").

We conducted a four-wave prospective study of Palestinian adults living in the West Bank, Gaza Strip, and East Jerusalem, interviewed between 2007 and 2009 at 6-month interval to explore transactional relationships between resource loss (i.e., intra and interpersonal resource loss) and psychological distress (i.e., posttraumatic stress disorder and depression symptoms). Initially, 1196 Palestinians completed the first wave interview and 752 of these participants completed all four interviews. A cross-lagged panel design was constructed to model the effects of trauma exposure on both resource loss and psychological distress and the subsequent reciprocal effects of resource loss and psychological distress across four time waves. Specifically, resource loss was modeled to predict distress, which in turn was expected to predict further resource loss. Structural equation modeling was used to test this design. We found that psychological distress significantly predicts resource loss across shorter, 6-month time waves, but that resource loss predicts distress across longer, 12-month intervals. These findings support the Conservation of Resources theory's corollary of loss spirals. [ABSTRACT FROM PUBLISHER]

Coming out of the resource dilemma to realize the sustainable development is a tough task for resource-based cities. In these cities, one-fold industrial structure, unreasonable economic structure, serious environmental crisis and inappropriate human resource arrangement are hindering further development. The comprehensive evaluation method can quantify the effects of transition, and more detailed analysis of effects can be traced to the score of the three first level indexes: social development, economic development and environmental protection. The shortcomings of a resource-based city can also be seen from the results, so further improved schemes will be processed. The comprehensive evaluation can help find a reasonable method from the three transition methods: (1) the extension of industrial chain (2) the implantation of new industries (3) the support of new dominant industries.

The topic of biodiversity is of high value for education for sustainable development as it reflects the interaction of ecological, economic and social issues particularly well. Especially in so-called biodiversity hotspots, among them Chile, natural resources are often depleted for economic interest which, in many cases, is required income. Therefore, economic and social aspects must be considered in order to fully understand biodiversity loss. Being such an important issue, it is surprising that little is known thus far about learning prerequisites concerning biodiversity. This paper presents a qualitative interview study that investigated 16 to 18-year-old Chilean and German learners’ perception of biodiversity and its loss ( n = 24). Firstly, the pupils’ cognitive frameworks were analysed. Secondly, subjective theories about biodiversity loss due to resource dilemmas were explored. Three subjective theories that emerged from the data reflected the notion that most pupils focused on either ecological or economic aspects of biodiversity loss. Pupils who concentrated on ecological aspects often referred to incorrect ecological facts. Moreover, these pupils showed difficulties in developing empathy and solidarity with impoverished people, who depend economically on plants in a resource dilemma. A smaller group of pupils succeeded in integrating the ecological, economic, and social aspects. Regarding the two samples, Chilean pupils seemed to have greater difficulties in recognising the social aspects of biodiversity loss, while German pupils were largely unaware of biodiversity loss on a local level. Implications for biodiversity education and future research will be outlined and discussed. [ABSTRACT FROM AUTHOR]

Abstract: Three studies examined the impact of warnings about depleting resources. In Study 1, participants played 16 trials of a 5-person resource dilemma game with complete resource uncertainty. After trial 12, participants were told they were close to depleting the resource, and thereafter received no additional warnings. Size of harvests dropped after the warning, but rebounded within 3 trials to pre-warning levels, a pattern stronger under low harvesting variability. In Study 2, participants received warnings after trials 12 and 16 of a 22-trial game. Again, harvesting dropped after the first warning, but rebounded to pre-warning levels within 3 trials, a pattern stronger under a short-term vs. a long-term warning. Harvesting was unaffected by the second warning. In Study 3, when participants received no feedback about others'' harvests, harvesting dropped after both warnings, and was lower among those led to believe the resource would last a short number of trials.

Previous research on the allocation of scarce resources shows that when people are assigned labels of leader or follower in their group, leaders allocate more of the scarce resources to themselves than followers do. In three laboratory studies, we examine the idea that how people are selected for the leader role (i.e. election or appointment) determines whether leaders take more or equal shares (relative to followers) from a common resource. In a first experiment, we show that participants were more accepting of norm violating behavior by an appointed versus elected leader. In a second experiment, we show that when participants were assigned to a leader or follower role, allocations of appointed leaders differed significantly from those of elected leaders and followers, whereas there was no difference between the two latter conditions. Moreover, elected leaders were shown to feel more social responsibility than both appointed leaders and followers. In a final experiment, we show that when participants were primed with the concept of social responsibility (relative to a neutral condition) no difference in allocations between appointed and elected leaders emerged.

Abstract: This paper considers what kinds of knowledge, knowing and learning are required for addressing resource dilemmas in the context of sustainable development. It also explains why and how the SLIM project focused on social learning for managing water resources. The range of learning theories that informed SLIM are discussed, as is the historical pattern of lineages, relationships and discontinuities among these and other theories. Whilst conceptions of social learning are contested, most perspectives raise questions about the nature of knowledge and knowing. It is argued that becoming aware of our assumptions regarding learning, knowing and how we develop knowledge, can help us find out more about what we need to know. The nature of resource dilemmas, implications for learning, what learning involves, its interdisciplinary nature and its history of ideas are all considered. An overview of learning theories is given, explaining their potential relevance for researchers, policymakers and practitioners in environmental contexts. The discourse, theory and practice of social learning and factors that influenced the choice of social learning theories by SLIM researchers are discussed. The paper concludes by considering how understanding what social learning involves can contribute, in a practical way, to dealing with resource dilemmas. [Copyright &y& Elsevier]

Many environmental problems are resource dilemmas that contain two components–social and temporal–that encourage individuals not to act in the best interest of the group. Most research has focused on the social component. The authors examined the importance of the temporal component in two resource dilemma tasks. Participants (N = 112) reported their willingness to limit resource consumption in response to hypothetical dilemmas and forfeited extra credit points in response to a real dilemma. Cooperation rates were higher when the temporal dilemma was diminished, when uncertainty about environmental impacts was low, and for women. Individuals high in both proenvironmentalism and consideration of future consequences sustained high levels of cooperation even in the face of strong temporal dilemmas. [ABSTRACT FROM AUTHOR]

Experimental games are often used as models of social dilemmas in which small groups of players have unrestricted access to, and share, a common and finite resource of desirable goods in the absence of any binding coordination mechanism. Examples are fishing, hunting, and use of computational facilities. Experimental studies of social dilemmas employ different protocols of play that differ from each other in terms of the information available to the players when they register their requests from the common resource. In this study we focus on the sequential protocol, where each participant has complete information about his or her position and the total requests of the previous movers, and the positional protocol, where each player only knows his or her position, but has no information about the other's requests. Previous research has found a robust position effect: individual requests are inversely related to the players' positions in the sequence with the first mover requesting most, and the last mover requesting the least. In an attempt to characterize the nature and intensity of the position effect, we developed and tested a descriptive model with one free (individual specific) parameter. The parameter is estimated from the players' requests under the positional protocol (i.e. in the absence of any information about the other's requests) and. as such, quantifies the social norm of 'advantage of the early mover'. In a range of eases examined, including different group sizes, resource pool sizes, and positions, the model predicted very accurately individuals' requests in the sequential protocol (with full information about position and others' requests).
