Un 7-Eleven de la ciudad de Brisbane deberá pagar casi 200.000 dólares de multa por aprovecharse de sus trabajadores extranjeros y crear registros falsos para encubrir estas acciones ilegales. Este caso se suma a la serie de escándalos de explotación que afectan a esta franquicia, seis de ellas en la capital de Queensland. Updated Updated 05/06/2018 By R.O. Share Share on Facebook Share on Twitter  Un Tribunal del Circuito Federal multó a Avinash Pratap Singh, gerente y dueño parcial de una gasolinera 7-Eleven en East Brisbane, con 32.130 dólares y a la empresa que dirige S & A Enterprises con otros160.650 dólares tras una investigación realizada en 2015 por la Defensoría de Empleo Justo (Fair Work Ombudsman).Los inspectores de la Defensoría hallaron que los empleados, todos ellos jóvenes estudiantes provenientes de la India, recibieron 5,593 dólares menos en total por los períodos en que trabajaron en la gasolinera en 2014.Singh y su empresa admitieron que pagaron a sus empleados 14,14 por hora, que está por debajo del salario mínimo legal, y que además no les dieron a estos jóvenes el dinero que les correspondía por horas extras trabajadas ni por las jornadas durante los fines de semana y los días festivos.A otro empleado de la gasolinera se le pagó un 25 por ciento menos de lo que le correspondía (4,439 dólares) por los cinco meses que trabajó, mientras que a otro joven se le dio 1,154 dólares menos durante las siete semanas que estuvo empleado en ese lugar (41 por ciento menos(.Singh y S & A Enterprises también proporcionaron datos falsos a la oficina central de 7-Eleven sobre los salarios, según un comunicado de la Defensoría de Empleo Justo.El juez Angelo Vasta indicó que la entrada de datos falsos sobre las horas y los salarios dados a los empleados de esa gasolinera en el sistema de pagos “crearon registros en los que parece que los empleados recibieron las tasas de salarios fijados por los laudos actuales, incluyendo las tasas de recargo y las pagas por horas extraordinarias de trabajo, las cuales no tienen relación con las horas de trabajo o las tasas reales por hora (que se les pagó)”.El juez además obligó a los responsables a pagar a la Defensoría 2,247 por los costes legales.

Mr Chang admitted his company had paid flat hourly rates as low as $13 an hour. 7-Eleven investigation 7-Eleven playing 'statistical tricks' in worker compensation scheme'He made me scared': 7-Eleven worker speaks of intimidationExploitation integral to 7-Eleven business model: insider7-Eleven staff work twice as long at half pay rate7-Eleven business model rips off workers, former ACCC boss saysConvenience store empire 'built on something not much different from slavery' This resulted in significant underpayment of the minimum hourly rate, casual loadings and penalty rates for shift and weekend work that employees were owed under the General Retail Award 2010.Judge Michael Jarrett found Mr Chang knew the relevant Award that applied but had "established a business model that relied upon a deliberate disregard of the employees' workplace entitlements and a course of conduct designed to conceal that deliberate disregard".Judge Jarrett found no evidence the company's contraventions were motivated by poor cash flow.He said "rather, it seems, the company's profit has been enhanced by the underpayments concerned".The FWO confirmed all underpayments had been rectified."Businesses should be in no doubt that lawful obligations to pay minimum wage rates, keep appropriate employment records and issue pay slips apply to all employers in Australia and they are not negotiable," Fair Work Ombudsman Natalie James said."The deliberate nature of the underpayments and the lengths that Mr Chang went to in order to hide his conduct from us and from the 7-Eleven head office is of grave concern."Mr Chang was fully aware of his lawful obligations and chose to manipulate the system in order to undercut the entitlements of vulnerable workers. "We are pleased that the court has seen fit to penalise such blatant conduct and hope that this serves as a warning that such behaviour will be penalised."Mr Chang and his company sold the 7-Eleven franchise in late-2016 and the franchise is now operated by an entity unrelated to these contraventions.The FWO said it had taken legal action against nine 7-Eleven operators since 2009, and that cases against three operators were still before the courts.7-Eleven's Australian head office has since commented on the court decision."7-Eleven welcomes the Fair Work Ombudsman's actions pursuing these wage underpayment claims dating back to 2013-14," a company spokesperson said."The Franchisee concerned is no longer part of our store network."We have introduced comprehensive reforms to ensure our Franchised store network operates at the highest standards we expect, and will take action where those standards are not being met."

The penalties are the result of a legal action by the Fair Work Ombudsman after its investigation found that 21 employees across the two stores had been underpaid a total of $31,507.27 over a 12-month period. Viplus Pty Ltd, which operated a store in Adelaide Street until July 2017, was penalised $88,140, while Vipper Pty Ltd, which operated a store in George Street until May 2017, was penalised $68,262. Penalties totalling $36,559 were also handed down against Jason Yuan, a director of both companies. The stores were two of 20 7-Eleven outlets targeted for surprise night-time visits by the Fair Work Ombudsman as part of a tri-State operation in September 2014. The Fair Work Ombudsman has taken legal action against 11 7-Eleven operators since 2009. In this matter, inspectors found that the workers at both stores were paid flat rates for all hours worked, save for public holidays where they received an additional $20 per hour in cash.  Given the 24 hour, seven-day nature of the businesses, this resulted in significant underpayments of Saturday and public holiday penalty rates, overtime rates and shift work rates stipulated by the General Retail Industry Award 2010. Two workers at the Adelaide Street store were also found to have been paid at the incorrect classification. Individual underpayments ranged from $98.36 to $5080.16. They have all now been rectified The respondents were also penalised for failing to meet record-keeping and payslip requirements, including by failing to include information in respect of cash payments made to some of the employees. In her judgment, Judge Mercuri noted that the underpayments were “substantial”, particularly given the low-skilled nature of the work and the vulnerability of the workers due to their age and, in some cases, their visa status. “Given that many of the employees of both Viplus and Vipper were in Australia on various visas, with many being young workers, the impact of the underpayments was significant for each of the affected employees,” Judge Mercuri said. In determining the penalties, Judge Mercuri also pointed out that Mr Yuan had been running the stores for over twelve years, had a background in finance, banking and project management and had access to significant training and support from the 7‑Eleven head office. In addition, her Honour noted the Fair Work Ombudsman had previously issued Vipper and Mr Yuan with a letter of caution in 2013 after an investigation found that workers at the Adelaide Street store were not being paid applicable weekend and public holiday penalty rates. At the time, the Fair Work Ombudsman advised Mr Yuan about his obligations to pay penalty rates as stipulated under the Award. Judge Mercuri found this “continued failure to ensure compliance with the Award following the issuing of a letter of caution to Vipper Pty Ltd” to be a relevant factor in determining the penalties for Vipper and Mr Yuan. Acting Fair Work Ombudsman Kristen Hannah says that the regulator takes a particularly dim view of employers who continue to breach workplace laws after being explicitly advised of their obligations. “Employers must recognise that significant consequences will follow when they knowingly flout the law,” Ms Hannah says. “There is no excuse for continued non-compliance by a business when it has been placed on notice and we will not hesitate to pursue serious enforcement action when this occurs. “We have no patience for business operators who fail to respect the law and ignore our advice, and the penalties handed down in this case reflect the seriousness with which such matters will be dealt.” Ms Hannah says that the Fair Work Ombudsman takes the exploitation of young workers and visa holders particularly seriously. “We know that these cohorts face specific vulnerabilities in the workplace due to a lack of awareness of workplace laws and a reluctance to speak up if something is wrong,” Ms Hannah says. “There is no place for the deliberate exploitation of vulnerable workers in Australian workplaces.” Ms Hannah says the commencement of the Fair Work Amendment (Protecting Vulnerable Workers) Act 2017 has increased the maximum penalties for employers who knowingly exploit workers. “Businesses should be aware that serious breaches of workplace laws have increased ten-fold and can now attract penalties of up to $630,000 per contravention for companies and $126,000 for an individual,” Ms Hannah says. 7-Eleven entered into a Proactive Compliance Deed with the Fair Work Ombudsman in late 2016, committing to a range of measures designed to ensure all its workers receive their lawful entitlements through strong accountability for all operators across its franchise network and supervision by the Fair Work Ombudsman.

The urgency of time may make it too onerous forthe extra effort of articulating actions as they are beingperformed, yet most emergency response requires somecommunication.

Explicitly articulated narratives mayalso make clearer that multiple sequences of actions maybe occurring simultaneously, thus resolving role conflictsby allowing multiple ways to accomplish a task

Experimentation, the third affordance, refers to theuse of technology to encourage participants to try outnovel ideas.

Recombinability refers to forms of technology-enabled action where individual contributors build oneach others’ contributions.

Reviewability refers to the enactment of technology-enabled new forms of working in which participantsare better able to view and manage the content offront and back narratives over time (West and Lakhani2008). By allowing participants to easily and collab-oratively review a range of ideas, technology-affordedreviewability helps the community respond to tensionsin disembodied ideas, because the reviews can provideimportant contextual information for building on others’ideas.

Technology platforms used by OCs can providea number of affordances for knowledge collabora-tion, three of which we mention here: reviewability,recombinability, and experimentation. These affordancesevolve as new participants provide new ways to use thetechnologies, new social norms are developed around thetechnology affordances, and new needs for fresh affor-dances are identified.

Given the fluid nature of OCsand their rapidly evolving technology platforms, and inline with calls to avoid dualistic thinking about tech-nology (Leonardi and Barley 2008, Markus and Silver2008, Orlikowski and Scott 2008), we suggest technol-ogy affordance as a generative response, one that viewstechnology, action, and roles as emergent, inseparable,and coevolving. Technology affordances offer a relationalperspective on human action, where neither the technol-ogy nor the actor is dominant in the sense that the tech-nology does not define what is possible for the actor todo, nor is the actor free from the limitations of the tech-nological environment. Instead, possibilities for actionemerge from the reciprocal interaction between actor andartifact (Gibson 1979, Zammuto et al. 2007). Thus, anaffordance perspective focuses on the organizing actionsthat are afforded by technology artifacts.

third response to manage tensions is to promoteknowledge collaboration by enacting dynamic bound-aries. In social sciences, although boundaries divide anddisintegrate collectives, they also coordinate and inte-grate social action (Bowker and Star 1999, Lamont andMolnár 2002). Fluidity brings the need for flexible andpermeable boundaries, but it is not only the propertiesof the boundaries but also their dynamicity that helpmanage tensions.

We have observed in OCs that no single narrative isable to keep participants informed about the current stateof the OC with respect to each tension. These commu-nities seem to develop two different types of narratives.Borrowing from Goffman (1959), we label the two nar-ratives the “front” and the “back” narratives.

Based on our collective research on to date, we haveidentified that as tensions ebb and flow, OCs use (or,more precisely, participants engage in) any of the fourtypes of responses that seem to help the OC be gen-erative. The first generative response is labeledEngen-dering Roles in the Moment. In this response, membersenact specific roles that help turn the potentially negativeconsequences of a tension into positive consequences.The second generative response is labeledChannelingParticipation. In this response, members create a nar-rative that helps keep fluid participants informed ofthe state of the knowledge, with this narrative havinga necessary duality between a front narrative for gen-eral public consumption and a back narrative to airthe differences and emotions created by the tensions.The third generative response is labeledDynamicallyChanging Boundaries. In this response, OCs changetheir boundaries in ways that discourage or encouragecertain resources into and out of the communities at cer-tain times, depending on the nature of the tension. Thefourth generative response is labeledEvolving Technol-ogy Affordances. In this response, OCs iteratively evolvetheir technologies in use in ways that are embedded by,and become embedded into, iteratively enhanced socialnorms. These iterations help the OC to socially and tech-nically automate responses to tensions so that the com-munity does not unravel.

Tension 5: Positive and Negative Consequences ofTemporary ConvergenceThe classic models of knowledge collaboration in groupsgive particular weight to the need for convergence. Con-vergence around a single goal, direction, criterion, pro-cess, or solution helps counterbalance the forces ofdivergence, allowing diverse ideas to be framed, ana-lyzed, and coalesced into a single solution (Couger 1996,Isaksen and Treffinger 1985, Osborn 1953, Woodmanet al. 1993). In fluid OCs, convergence is still likelyto exist during knowledge collaboration, but the conver-gence is likely to be temporary and incomplete, oftenimplicit, and is situated among subsets of actors in thecommunity rather than the entire community.

ension 2: Positive and Negative Consequencesof TimeA second tension is between the positive and negativeconsequences of the time that people spend contribut-ing to the OC. Knowledge collaboration requires thatindividuals spend time contributing to the OC’s virtualworkspace (Fleming and Waguespack 2007, Lakhani andvon Hippel 2003, Rafaeli and Ariel 2008). Time has apositive consequence for knowledge collaboration. Themore time people spend evolving others’ contributedideas and responding to others’ comments on thoseideas, the more the ideas can evolve

We argue that it is the fluidity, the tensions that flu-idity creates, and the dynamics in how the OC respondsto these tensions that make knowledge collaboration inOCs fundamentally different from knowledge collabora-tion in teams or other traditional organization structures.

As fluctuations in resource endowments arise overtime because of the fluidity in the OC, these fluctua-tions in resources create fluctuations in tensions, makingsimple structural tactics for managing tensions such ascross-functional teams or divergent opinions (Sheremata2000) inadequate for fostering knowledge collaboration.As complex as these tension fluctuations are for the com-munity, it is precisely these tensions that provide thecatalyst for knowledge collaboration. Communities thatthen respond to these tensions generatively (rather thanin restrictive ways) will be able to realize this potential.Thus, it is not the simple presence of resources that fos-ter knowledge collaboration, but rather the presence ofongoing dynamic tensions within the OC that spur thecollaboration. We describe these tensions in the follow-ing section

Fluidity requires us to look at the dynamics—i.e., thecontinuous and rapid changes in resources—rather thanthe presence or the structural form of the resources.Resources may flow from outside the OC (e.g., pas-sion) or be internally generated (e.g., convergence), sub-sequently influencing and influenced by action (Feldman2004). Resources come with the baggage of having bothpositive and negative consequences for knowledge col-laboration, creating a tension within the community inhow to manage the positive and negative consequencesin a manner similar to the one faced by ambidextrousorganizations (O’Reilly and Tushman 2004).

However, failure to examine the critical roleof even the inactive participants in the functioning of thecommunity is to ignore that passive (and invisible) par-ticipation may be a step toward greater participation, aswhen individuals use passivity as a way to learn aboutthe collective in a form of peripheral legitimate partici-pation (Lave and Wenger 1991, Yeow et al. 2006).

Fluidity recognizes the highly flexible or permeableboundaries of OCs, where it is hard to figure out whois in the community and who is outside (Preece et al.2004) at any point in time, let alone over time. Theyare adaptive in that they change as the attention, actions,and interests of the collective of participants change overtime. Many individuals in an OC are at various stagesof exit and entry that change fluidly over time.

We argue that fluid-ity is a fundamental characteristic of OCs that makesknowledge collaboration in such settings possible. Assimply depicted in Figure 1, we envision OCs as fluidorganizational objects that are simultaneously morphingand yet retaining a recognizable shape (de Laet and Mol2000, Law 2002, Mol and Law 1994).

a growing consensus on factors that moti-vate people to make contributions to these communities,including motivational factors based on self-interest (e.g.,Lakhani and von Hippel 2003, Lerner and Tirole 2002,von Hippel and von Krogh 2003), identity (Bagozzi andDholakia 2006, Blanchard and Markus 2004, Ma andAgarwal 2007, Ren et al. 2007, Stewart and Gosain2006), social capital (Nambisan and Baron 2010; Waskoand Faraj 2000, 2005; Wasko et al. 2009), and socialexchange (Faraj and Johnson 2011).

For instance, knowledge collaboration in OCscan occur without the structural mechanisms tradition-ally associated with knowledge collaboration in orga-nizational teams: stable membership, convergence afterdivergence, repeated people-to-people interactions, goal-sharing, and feelings of interdependence among groupmembers (Boland et al. 1994, Carlile 2002, Dougherty1992, Schrage 1995, Tsoukas 2009).

Knowledge collaboration is defined broadly as thesharing, transfer, accumulation, transformation, andcocreation of knowledge. In an OC, knowledge collab-oration involves individual acts of offering knowledgeto others as well as adding to, recombining, modify-ing, and integrating knowledge that others have con-tributed. Knowledge collaboration is a critical elementof the sustainability of OCs as individuals share andcombine their knowledge in ways that benefit them per-sonally, while contributing to the community’s greaterworth (Blanchard and Markus 2004, Jeppesen andFredericksen 2006, Murray and O’Mahoney 2007, vonHippel and von Krogh 2006, Wasko and Faraj 2000).

Online communities (OCs) are open collectives of dis-persed individuals with members who are not necessarilyknown or identifiable and who share common inter-ests, and these communities attend to both their indi-vidual and their collective welfare (Sproull and Arriaga2007).

The situated and emergent nature of coordinationdoes not imply that practices are completely uniqueand novel. On the one hand, they vary accordingto the logic of the situation and the actors present.On the other hand, as seen in our categorizationof dialogic coordination, they follow a recognizablelogic and are only partially improvised. This tensionbetween familiarity and uniqueness of response is atthe core of a practice view of work (Orlikowski 2002).

Recently, Brown and Duguid (2001, p. 208) sug-gested that coordination of organizational knowledgeis likely to be more challenging than coordination ofroutine work, principally because the “elements to becoordinated are not just individuals but communitiesand the practices they foster.” As we found in ourinvestigation of coordination at the boundary, signif-icant epistemic differences exist and must be recog-nized. As the dialogic practices enacted in responseto problematic trajectories show, the epistemic dif-ferences reflect different perspectives or prioritiesand cannot be bridged through better knowledge

nature point to the limitations of a structuralist viewof coordination. In the same way that an organi-zational routine may unfold differently each timebecause it cannot be fully specified (Feldman andPentland 2003), coordination will vary each time.Independent of embraced rules and programs, therewill always be an element of bricolage reflecting thenecessity of patching together working solutions withthe knowledge and resources at hand (Weick 1993).Actors and the generative schemes that propel theiractions under pressure make up an important com-ponent of coordination’s modus operandi (Bourdieu1990, Emirbayer and Mische 1998).

These practices are highly situated, emer-gent, and contextualized and thus cannot be prespec-ified the way traditional coordination mechanismscan be. Thus, recent efforts based on an information-processing view to develop typologies of coordina-tion mechanisms (e.g., Malone et al. 1999) may be tooformal to allow organizations to mount an effectiveresponse to events characterized by urgency, novelty,surprise, and different interpretations.

Our findings also point to a broader divide in coor-dination research. Much of the power of traditionalcoordination models resides in their information-processing basis and their focus on the design issuessurrounding work unit differentiation and integra-tion. This design-centric view with its emphasis onrules,structures,andmodalitiesofcoordinationislessuseful for studying knowledge work.

Boundarywork requires the ability to see perspectives devel-oped by people immersed in a different commu-nity of knowing (Boland and Tenkasi 1995, Star andGriesemer 1989). Often, particular disciplinary focilead to differences in opinion regarding what stepsto take next in treating the patient.

The termdialogic—as opposed to monologic—recognizes dif-ferences and emphasizes the existence of epistemicboundaries, different understandings of events, andthe existence of boundary objects (e.g., the diagnosisor the treatment plan). A dialogic approach to coordi-nation is the recognition that action, communication,and cognition are essentially relational and highlysituated. We use the concept of trajectory (Bourdieu1990, Strauss 1993) to recognize that treatment pro-gressions are not always linear or positive.

A dialogic coordination practice differs from moregeneral expertise coordination processes in that itis highly situated in the specifics of the unfoldingevent, is urgent and high-staked, and occurs at theboundary between communities of practice. Becausecognition is distributed, responsibility is shared, andepistemic differences are present, interactions can becontentious and conflict laden.

xpertisecoordination refers to processes that manage knowl-edge and skill interdependencies

we describe two categories ofcoordination practices that ensure effective work out-comes. The first category, which we callexpertise coor-dination practices, represents processes that make itpossible to manage knowledge and skill interdepen-dencies. These processes bring about fast response,superior reconfiguration, efficient knowledge shar-ing, and expertise vetting. Second, because of therapidlyunfoldingtempooftreatmentandthestochas-tic nature of the treatment trajectory,dialogic coordina-tion practicesare used as contextually and temporallysituated responses to occasional trajectory deviation,errors, and general threats to the patient. These dia-logic coordination practices are crucial for ensuringeffective coordination but often require contentiousinteractions across communities of practice. Figure 1presents a coordination-focused model of patienttreatment and describes the circumstances underwhich dialogic coordination practices are called for.

We found that coordination in a trauma settingentails two specific practices.

Based on a practice view, we suggest the followingdefinition ofcoordination: a temporally unfolding andcontextualized process of input regulation and inter-action articulation to realize a collective performance.

Theprimarygoalispatientstabilizationandini-tiating atreatment trajectory—a temporally unfolding

rauma centersare representative of organizational entities that arefaced with unpredictable environmental demands,complexsetsoftechnologies,highcoordinationloads,and the paradoxical need to achieve high reliabilitywhile maintaining efficient operations.

We sug-gest that for environments where knowledge work isinterdisciplinary and highly contextualized, the rele-vant lens is one of practice. Practices emerge from anongoing stream of activities and are enacted throughthe contextualized actions of individuals (Orlikowski2000). These practices are driven by a practical logic,thatis,arecognitionofnoveltaskdemands,emergentsituations,andtheunpredictabilityofevolvingaction.Bourdieu (1990, p. 12) definespracticesas generativeformulas reflecting the modus operandi (manner ofworking) in contrast to the opus operatum (finishedwork).

In knowledge work, several related factors sug-gest the need to reconceptualize coordination.

Usinga practice lens (Brown and Duguid 2001, Orlikowski2000), we suggest that in settings where work iscontextualized and nonroutine, traditional models ofcoordination are insufficient to explain coordinationas it occurs in practice. First, because expertise is dis-tributed and work highly contextualized, expertisecoordination is required to manage knowledge andskill interdependencies. Second, to avoid error andto ensure that the patient remains on a recoveringtrajectory, fast-response cross-boundary coordinationpractices are enacted. Because of the epistemic dis-tance between specialists organized in communitiesofpractice,theselattercoordinationpracticesmagnifyknowledge differences and are partly contentious.

In this paper, we focus on the collective perfor-manceaspectofcoordinationandemphasizethetem-poral unfolding and situated nature of coordinativeaction. We address how knowledge work is coor-dinated in organizations where decisions must bemade rapidly and where errors can be fatal.

In other words, the articulation work [24], which had to be made explicit previously, became in part implicit by being embedded in the document and in the actions taken upon the document.

By ignoring the diversity and discord of the ‘goals’ of theparticipants involved, the differentiation of strategies, and the incongruence of theconceptual frames of reference within a cooperating ensemble, much of the currentCSCW research evades the problem of how to provide computer support for peoplecooperating through the establishment of a common information space.

On the one hand, the visibility requirement is amplified by this divergence. Thatis, knowledge of the identity of the originator and the situational context motivat-ing the production and dissemination of the information is required so as to enableany user of the information to interpret the likely motives of the originator. On theother hand, however, the visibility requirement is moderated by the divergence ofinterests and motives. A certain degree of opaqueness is required for discretionarydecision making to be conducted in an environment charged with colliding inter-ests. Hence,visibility must be bounded.

Thus, a computer-basedsystem supporting cooperative work involving decision making should enhancethe ability of cooperating workers to interrelate their partial and parochial domainknowledge and facilitate the expression and communication of alternative perspec-tives on a given problem. This requires a representation of the problem domainas a whole as well as a representation, in some form, of the mappings betweenperspectives on that problem domain.

If the decision making process (1) involves a large and indefinite number of peo-ple, (2) requires the integration of a number of different perspectives or domains,and (3) continues for a protracted period of time or even indefinitely, the interpreta-tion of the objects in a common database and hence the construction of a commoninformation space is hampered by the fact that the other originators and recipientsare not co-present.

The fact that information produced by discretionary decision making cannotbe conveyed anonymously has important implications for CSCW systems design.Naturally, such information must be accompanied by the identity of the source.But how to represent and present the identity of the source?

In cooperative work settings involving discretionary decision making, the exer-cise of mutual critique of the decisions arrived at by colleagues is required for allparticipants. Therefore, in order to be able to assess information generated by dis-cretionary decision making, each participant must be able to access the identity ofthe originator of a given unit of information.

At the level of the objects themselves, shareabilitymay not be a problem, but in terms of their interpretation, the actors must attempt tojointly construct a common information space which goes beyond their individualpersonal information spaces. A nice example of how this is a problem has been givenby Savage (1987, p. 6): ‘each functional department has its own set of meaningsfor key terms. [...] Key terms such aspart, project, subassembly, toleranceareunderstood differently in different parts of the company.’

Their importance lies in the interpretation human actors place on themeaning of the representational object. The distinction between the material carrierof information—the object—and its meaning is crucial. The material representationof information in the common space (e.g., a letter, memo, drawing, file) exists asan objective phenomenon and can be manipulated as an artifact. The semantics ofthe information carried by the artifact, however, is, put crudely, ‘in the mind’ of thebeholder, and the acquisition of information conveyed by the artifacts requires aninterpretive activity on the part of the recipient. Thus, a common information spaceencompasses the artifacts that are accessible to a cooperative ensembleas well asthe meaning attributed to these artifacts by the actors.

Cooperative work is not facilitated simply by the provision of a shared database, butrequires the active construction by the participants of a common information spacewhere the meanings of the shared objects are debated and resolved, at least locallyand temporarily. Objects must thus be interpreted and assigned meaning, meaningsthat are achieved by specific actors on specific occasions of use. Computer supportfor this aspect of cooperative work raises a host of interesting and difficult issues.

These protocols, formal structures, plans, procedures, and schemes can be con-ceived of asmechanismsin the sense that they (1) are objectified in some way(explicitly stated, represented in material form), and (2) are deterministic or at leastgive reasonably predictable results if applied properly. And they aremechanisms ofinteractionin the sense that they reduce the complexity of articulating cooperativework.

Therefore, instead of pursuing the elusive aim of devising organizational modelsthat are not limited abstractions and thus in principle brittle when confronted withthe inexhaustible multiplicity of reality, organizational models in CSCW applica-tions should be conceived of asresourcesfor competent and responsible workers.

In this section of the paper we broach two aspects of this articulation issue, onefocusing on the management of workflow, the other on the construction and manage-ment of what we term a ‘common information space’. The former concept has beenthe subject of discussion for some time, in the guise of such terms as office automa-tion and more recently, workflow automation. The latter concept has, in our view,been somewhat neglected, despite its critical importance for the accomplishmentof many distributed work activities

Articulation work

However, in general cooperative workin real world settings has a number of characteristics that must be taken into accountif CSCW systems are to be acceptable to users and, hence, commercially viable:

A cooperative work arrangement arises simply because there is no omniscientand omnipotent agent. Specifically, a cooperative work arrangement may emerge inresponse to different requirements (Schmidt,1990):

The Rich Diversity of Cooperative Work

As a research effort that involves a large number of established disciplines,research areas, and communities, CSCW is an arena of discordant views, incom-mensurate perspectives, and incompatible agendas. However, in the conception ofCSCW proposed here—as a research area devoted to exploring and meeting the sup-port requirements of cooperative work arrangements, CSCW is basically adesignoriented research area. This is the common ground. Enter, and you must change.

CSCW should be conceived of asan endeavor to understand the nature andrequirements of cooperative work with the objective of designing computer-basedtechnologies for cooperative work arrangements.

The result of this is easy to see: Those specifically requesting a lighter workload, who were disproportionately women, suffered in their performance reviews; those who took a lighter workload more discreetly didn’t suffer. The maxim of “ask forgiveness, not permission” seemed to apply.

these systems were very slow, had a low assembly or operation yield, or were unable to exert appreciable forces against external loading.

Then I noticed, each of the records in his queue had a set of codes in the Salutation field. He explained that there wasn't a way to see the current status from this view of their system. So, to avoid having to open each record, he used the Salutation field (which wasn't really used in the system) to store his own personal status codes.

Once she finished, there was basically a cross-reference table of items that were actual business aspects and how they translated into the items required to use this system. In short, the last system that was delivered by the IT group required a change in the business process to use the application.

Transformed in this process is the very nature of knowledge:Neoliberalization replaces education aimed at deepening and broadening intelligence and sensibilities, developing historical consciousness and her-meneutic adroitness, acquiring diverse knowledge and literacies, becom-ing theoretically capacious and politically and socially perspicacious, with [forms of] education aimed at honing technically-skilled entrepreneurial actors adept at gaming any system.

The goal of this framework is to envision afuture of crowd work that cansupport more complex, creative, and highly valued work. At the highest level, a platformis needed for managing pools of tasksandworkers. Complex tasks must be decomposed into smaller subtasks, each designed with particular needs and characteristics which must be assignedto appropriate groups of workerswho themselves must be properly motivated, selected(e.g., through reputation), and organized (e.g., through hierarchy). Tasks may be structured through multi-stage workflowsin which workers may collaborateeither synchronously or asynchronously. As part of this, AImay guide (and be guided by) crowd workers. Finally, quality assuranceis needed to ensure each worker’s output is of high quality and fits together.

n human computation, people act as computational components and perform the work that AI systemslack the skillstocomplete

A promising approach that addresses some worker output issues examines the way that workers do their work rather than the output itself, using machine learning and/or visualization to predict the quality of a worker’s output from their behavior [119,120]

Of the research foci, quality control has arguably received the most attention so far. Approaches for quality control largely fall into two camps: up-front task design and post-hoc result analysis. Task design aimsto design tasks that are resistant to low-quality work.

Many tasks worth completing require cooperation –yet crowdsourcing has largely focused on independent work. Distributed teams have always facedchallenges in cultural differences and coordination[60], but crowd collaboration now must createrapport over much shorter timescales(e.g., one hour) and possibly wider culturalor socioeconomic gaps

Finally, it will be amajor research undertaking to invent and describe the tasks and techniques that succeed with synchronous collaboration

The two core challenges for realtime crowdsourcing will be 1) scaling upto increased demand for realtime workers, and 2) making workers efficient enough to collectively generateresultsahead of time deadlines.

Volunteer crowdsourcing platforms have evolved their own hierarchies and decision-making processes [104,156], appropriating techniques from other online communities where appropriate [101]. Most paid approaches have workers make hierarchical decisions collectively: for example, task decomposition and integration[75,80],quality oversight of each others’ contributions[78,100], and leader elections to represent collective opinions[83].

Complex tasks have dependencies, changing requirements, and require multiple types of expertise.

n the sections below, we survey and analyze the 12research focithat comprise our model. First, we consider the future of the work processesand how the workis organized and accomplished. Second, we consider the integration of crowd work and computation, including the symbiosis between human cognition, artificial intelligence(AI), and computationally-enabled crowd platforms. Finally, we consider crowd workers and how we can develop jobs, reputation systems, motivations, and incentives that will benefit them.

Unlike traditional organizations in which workers possess job security and managers can closely supervise and appropriately reward or sanction workers, or distributed computing systems in which processors are usually highly reliable, crowd work poses uniquechallenges for both workers and requestersranging fromjob satisfactiontodirection-setting, coordination, and quality control.

These same requirements exist in distributed computing, in which tasks need to be scheduled so that they can be completed in the correct sequence and in a timely manner, with data being transferred between computing elements appropriately.

However, crowd work can bea double-edged sword,equally capable of enhancing or diminishing the quality of workers’ lives.We maysee echoes of past labor abuses in globally distributed crowd work: extremely low pay for labor,with marketplaces such as Amazon’s Mechanical

We focus this paper on paid,onlinecrowd work, which we define here as the performance of tasks online by distributed crowd workers who are financially compensated by requesters(individuals, groups, or organizations). In this sense, crowd work is a socio-technical work systemconstituted through a set of relationships that connect organizations, individuals, technologies and work activities

Other foundational accounts, like Moglen (1999) and Weber (2004),attended to the emergence of informal hierarchies and governance arrange-ments within communities.

Peer productioncould, Benkler argued, outperform traditional organizational forms underconditions of widespread access to networked communications technologies,a multitude of motivations driving contributions, and non-rival informationcapable of being broken down into granular, modular, and easy-to-integrate

While some of this research has been aimed at building technologies to better support multi-tasking, other research has been critical, pointing out the negative consequences of distraction and task-switching [29]. A parallel line of thinking, called ‘presence bleed’ [16], articulates the way that multi-tasking and extended temporal boundaries blur individuals’ professional and personal identities as work bleeds into and throughout multiple spheres

CSCW has been investigating the relationship of time and work practically from its inception as a scholarly fiel

beyond any reasonable doubt

Here, again, there is a motive under the surface; and, here again, I fancy that I can find it out.

Lev Vygotsky’s seminal work asserted that social interaction is a fundamental aspect of learning. And if he were alive today, he would most likely agree with the saying “two minds are better than one.” He might add, “Better yet, how about three or four?”

Attitudes towards looking like you’re working when you aren’t are akin to school policies that require students to perform attention, as though the performance of attention may be linked to actual attention, or even learning. The pretending takes precedence over the actual doing.

But what makes the story in places like Toledo and the region around it hard for many politicians and even economists to understand is that the anxiety goes well beyond automation and the number of jobs. For many people, your job defines your life.

I had a learning disability when I was in school. But I could do factory work. Factory work is what we did. Now robots do that job. What happens to people like me?

People have come to believe that they, their jobs, their communities, and the social contract that binds them to work and place and each other are under threat. And they’re not wrong.

Genetic studies have also suggested that Sox10and Ednrb do not interact during murine melanocyte development (Hakami et al., 2006).

High VEGF levels are in turn associated with poor prognosis in human melanoma tumors (Giatromanolaki et al., 2003).

Moreover, in situ melanomas appeared in adult skin grafts, while invasive melanomas developed in newborn skin grafts indicating that the susceptibility of skin to environmental tumor promoters is dependent on age (Berking et al., 2004).

Although Ednrb downregulation has been reported in some human melanoma cell lines (Eberle et al., 1999), other studies found Ednrb to be upregulated in most melanoma cell lines (Bittner et al., 2000; Ross et al., 2000). 

This suggests that Ednrb may function to activate tyrosinase production indirectly by inducing the production or secretion of Kitl (Hou et al., 2004).

This increase in cell numbers in the treated cultures could not be accounted for solely by a proliferative effect, pointing to a possible role for Edn3 in the survival of melanoblasts from the NC (Opdecamp et al., 1998).

Edn3 was most effective in promoting the long-term propagation of glia-melanocyte precursor cells as opposed to the other precursors (Real et al., 2006).
