Not only are public transport datasets useful for benchmarking route planning systems, they are also highly useful for benchmarking geospatial [13, 14] and temporal [15, 16] RDF systems due to the intrinsic geospatial and temporal properties of public transport datasets. While synthetic dataset generators already exist in the geospatial and temporal domain [17, 18], no systems exist yet that focus on realism, and specifically look into the generation of public transport datasets. As such, the main topic that we address in this work, is solving the need for realistic public transport datasets with geospatial and temporal characteristics, so that they can be used to benchmark RDF data management and route planning systems. More specifically, we introduce a mimicking algorithm for generating realistic public transport data, which is the main contribution of this work.

the field. Such a fresh approach possibly improves a wide range of conceptual issues in disasters and hazards. In addition, such an approach would give us insights on how disaster managers, emergency responders, and disaster victims (recognizing that these “roles” may overlap in some cases) see, use and experience time. This, in turn, could assist with a number of applied issues (e.g., warning, effective “response,” priorities in “recovery”) throughout the process of disaster.

Temporal differentiation helps substantiate elusive mental dis­tinctions. Like their spatial counterparts, temporal boundaries often represent mental partitions and thus serve to divide more than just time.

create the effect of temporal symmetry, of the group sharing a moment, even though individual members clearly read the message at different moments.

The notion of temporal structuring views "real time" not as an inherent property of Internet­based activities, or an inevitable consequence of technol­ogy use, but as an enacted temporal structure, reflecting the decisions people have made about how they wish to structure their activities, both on or off the Internet. As an alternative to the idea of '·real time," Bennett and Wei II ( 1997) have suggested the notion of "real-enough time," proposing that people design their process and technology infrastructures to accommodate variable timing demands, which are contingent on task and context. We believe such "real-enough" temporal structures are important ar­eas of further empirical investigation, allowing us to move beyond the fixation on a singular, objective "real time" to recognize the opportunities people have to (re)shape the range of temporal structures that shape their lives.

The notion of temporal structuring we have de­veloped here suggests instead that people enact multiple, heterogeneous, and shifting temporal structures in all as­pects of their lives.

Our empirical example also highlighted the value of achieving virtual temporal symmetry for members of a geographically dispersed community. As electronic me­dia become increasingly central to organizational life, in­dividuals may use asynchronous media in various ways to shape devices of virtual symmetry that help them co­ordinate across geographical distance and across multiple temporal structures. This suggests that when studying the use of electronic media, researchers should pay attention to the conditions in which virtual temporal symmetry may be enacted to coordinate distributed activities, and with what consequences. Interesting questions for empirical research include the following. As work groups in orga­nizations become more geographically dispersed and/or more dependent on electronic media, do members enact virtual temporal symmetry for certain purposes? If so, for which types of purposes? And how? If not, how do such work groups achieve temporal coordination?

By examining a community's repertoire of temporal struc­tures, we can understand the variety of ways in which community members' actions (re)produce the different temporal structures they constitute through their ongoing practices

The notion of temporal structuring focuses attention on what people actually do temporally in their practices, and how in such ongoing and situated activity they shape and are shaped by particular temporal structures. By exam­ining when people do what they do in their practices, we can identify what temporal structures shape and are shaped (often concurrently) by members of a community; how these interact; whether they are interrelated, over­lapping, and nested, or separate and distinct; and the ex­tent to which they are compatible, complementary, or contradictory.

In all these cases, the notion of temporal structuring through ongoing practices helps us understand and bridge the temporal oppositions underlying the research litera­ture. We tum now to an empirical example to demonstrate how this perspective can offer a new understanding of the temporal conditions and consequences of organizational life.

In practice, however. an open-ended or closed temporal orientation is not a stable property of occupational groups, but an emergent property of the temporal structures being enacted at a given moment by the groups' members.

Viewed from a practice perspective, the distinction be­tween cyclic and linear time blurs because it depends on the observer's point of view and moment of observation. In particular cases, simply shifting the observer's vantage point (e.g., from the corporate suite to the factory floor) or changing the period of observation (e.g., from a week to a year) may make either the cyclic or the linear aspect of ongoing practices more salient.

An emphasis on the cyclic temporality of organizational life also underpins the work on entrain­ment, developed in the natural sciences and gaining cur­rency in organization studies. Defined as "the adjustment of the pace or cycle of one activity to match or synchro­nize with that of another" (Ancona and Chong 1996, p. 251 ), entrainment has been used to account for a variety of organizational phenomena displaying coordinated or synchronized temporal cycles (Ancona and Chong 1996, Clark 1990, Gersick 1994, McGrath 1990).

In spite of the general movement from particular to­wards universal notions of time (Castells 1996, Giddens 1990, Zerubavel 1981 ), we can see that in use, all uni versa! temporal structures must be particularized to local contexts because they are enacted through the situated practices of specific community members in specific locations and time zones.

One such op­position is that between universal (global, standardized, acontextual) and particular (local, situated, context­specific) time.

Table 1 Different Perspectives on Time in Organizations

That is, people are purposive, knowledgeable, adaptive, and inventive ac­tors who, while they are shaped by established temporal structures, can also choose (whether explicitly or implic­itly) to (re)shape those temporal structures to accomplish their situated and dynamic ends.

scholars have begun to recognize the importance of what Nowotny (1992, p. 424) has termed pluritemporalism­"the existence of a plurality of different modes of social time(s) which may exist side by side." Our structuring lens sees this not so much as the existence of multiple times, but as the ongoing constitution of multiple tem­poral structures in people"s everyday practices.

Like social structures in general (Giddens 1984 ), tem­poral structures simultaneously constrain and enable.

While adopting one side or the other of this dichotomy may offer re­searchers analytic advantages in their temporal studies of organizations, difficulties arise when these positions are treated-not as conceptual tools-but as inherent prop­erties of time. Focusing on one side or the other misses seeing how temporal structures emerge from and are em­bedded in the varied and ongoing social practices of peo­ple in different communities and historical periods, and at the same time how such temporal structures powerfully shape those practices in turn. By focusing on what or­ganizational members actually do, our practice-based per­spective on temporal structuring may offer new insights into how people construct and reconstruct the temporal conditions that shape their lives.

Thus temporal structures, like all social structures (Giddens 1984), are both the medium and the outcome of people's recurrent practices.

This in­tegration suggests that time is instantiated in organiza­tional life through a process of temporal structuring,1 where people (re)produce (and occasionally change) tem­poral structures to orient their ongoing activities.

We contribute to this discussion within organizational re­search by offering an alternative third view-that time is experienced in organizational life through a process of temporal structuring that characterizes people's everyday engagement in the world. As part of this engagement, people produce and reproduce what can be seen to be temporal structures to guide, orient, and coordinate their ongoing activities.

emporal structures here are under­stood as both shaping and being shaped by ongoing hu­man action, and thus as neither independent of human action (because shaped in action), nor fully determined by human action (because shaping that action). Such a view allows us to bridge the gap between objective and subjective understandings of time by recognizing the ac­tive role of people in shaping the temporal contours of their lives, while also acknowledging the way in which people's actions are shaped by structural conditions out­side their immediate control.

Third, the use of time and temporality for mak-ing and giving sense to unfinalized stories, antenar-ratives and future scenarios (see Boje 2011), includ-ing attention to issues, such as temporal depth, timeurgency and temporal orientation in promoting theneed for short or long-term strategies (see Jabri 2016,p. 97; Kunischet al. 2017, p. 1043)

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]

User studies and intuition both suggest that the activities that a knowledge worker engages in change—sometimes dramatically—over time. Projects and milestones come and go, and the tools and information resources used within an activity often change over time as well. Furthermore, activities completed in the past and their outcomes often impact activities in the present, and ongoing activities will, in turn, affect activities that will be undertaken in the future. Capturing activity over the course of time has long been a problem for desktop computing.

This means also that the predominantly linear time is comp-lemented by greater awareness of cyclical times and temporal routines which are overlapping each other.

ut it will also have to come to terms with confronting 'the Other' (Fabian, 1983), with 'the curious asymmetry' still prevailing as a result of advanced industrial societies receiving a mainly endogenous and synchronic analytic treatment, while 'developing' societies are often seen in exogenous, diachronic terms. Study of 'Time and the Other' presupposes, often implicitly, that the Other lives in another time, or at least on a different time-scale. And indeed, when looking at the integrative but also potentially divisive 'timing' facilitated by modern communication and information-processing technology, is it not correct to say that new divisions, on a temporal scale, are being created between those who have access to such devices and those who do not? Is not one part of humanity, despite globalization, in danger of being left behind, in a somewhat anachronistic age?

At present, information and communication technologies con-tinue to reshape temporal experience and collective time consciousness (Nowotny, 1989b)

Although the spatio-temporal variation in rumor quantity and content has long been of interest to thefield, collecting data that accounts for temporalandspatial characteristics of rumoring has been extraordinarily difficult to dowith any degree of precision. Some have been able to capture rumoring data with some degree of temporal precision (Bordiaand Rosnow, 1998; Danzig, 1958; Greenberg, 1964) or with some spatial precision (Larsen, 1954), but bridging the two hasbeen difficult. Synthesizing temporal and spatial rumoring data across a wide variety of events had long been beyond thecapabilities of researchers. Simply gathering reliable data on rumoring was already fraught with challenges.

“Since one cannot distinguish a figure without a background, the present does not meaningfully exist without a past” (emphasis added; 2001, p. 608). As the background, the past provides a bench­mark for the present against which comparisons can be made. And such com­parisons indicate whether the present is the same as the past or different from it.

“the dynamic weaving of events, interactions, situations, and phases that comprise those relationships” (2000, p. 27), the dynamic weaving of events, interactions, and situations being very similar to narrative.

Personal and organizational histories occupy prominent figure positions in the figure-ground dichotomy, and that such histories are used to cope with the future is indicated by several pieces of evidence.

Temporal focus is the degree of emphasis on the past, present, and future (Blue­dorn 2000e, p. 124).

The results presented in Bluedorn (2000e) and the Appendix consistently support the distinction between temporal depth and temporal focus. Concep­tually the two terms refer to different phenomena, and empirical measures of the two share so little variance in common that for practical purposes they can be regarded as orthogonal. Temporal depth is the distance looked into past and

However, Boyd and Zimbardo’s interest was not in comparing short-, mid-, and long-term temporal depths; rather, it was in examining the degree to which people were oriented to a transcendental future, and in exam­ining the extent to which this variation covaried with other factors such as age, gender, and ethnicity. This is a natural extension of the questions involved in research on general past, present, and future temporal orientations (e.g., Kluck- hohn and Strodtbeck 1961, pp. 13-15), orientations that at first glance appear similar to issues of temporal depth. However, as I have argued elsewhere in opposing the use of the temporal orientation label, these general orientations are more an issue of the general temporal direction or domain that an individ­ual or group may emphasize (Bluedorn 2000e) than the distance into each that the individual or group typically uses. The latter is the issue of temporal depth; the former, what I have called temporal focus (Bluedorn 2000e)

And the determination of organizational age illustrates the constructed, enacted nature of the past, because what at first glance seems like a simple, even objective matter becomes ambiguous when mergers and acquisitions are involved. Is the founding date the date that the oldest of the merger partners began operations, or is it the date when the last partners merged? Families can face the same ambiguities when one or both spouses have been married previously and they and their children combine to form new families. As the definition of the situation principle teaches (see Chapter 1), the important is­sue is when the people in the organization or family believe it was founded.

Steve Ferris and I found that organizational age was positively correlated with both past and future temporal depths, and that these relationships per­sisted after controlling for several organizational and environmental variables (Bluedorn and Ferris 2000). The older the organization, the further its mem­bers looked into both the past and the future, and the positive temporal depth correlations with the organization’s age may suggest why

The past leads to and influences the future, but the future does not influence the past.Thus El Sawy s research provided a second clue that past and future are re­lated, and it even added a causal direction (i.e., “A connection to the past fa­cilitates a connection to the future” [March 1999, p. 75])·

the result is a statistically significant positive correlation (see the Appendix). The proposed connection is accurate: The longer the respondent’s past temporal depth, the longer the respondent’s future temporal depth.

Perhaps the most noteworthy of the differ­ences is that each of the future regions extends much further into the future than their past counterparts extend into the past. The short-term future ex­tends about five times further than does the recent past; the mid-term future, about three-and-one-third times as far as the middling past; and the long­term future, about twice as far as the long-ago past. So although the steplike pattern is similar for both the past and future regions, the future depths extend over substantially larger amounts of time than do those in the past

the temporal distances into the past and future that indi­viduals and collectivities typically consider when contemplating events that havehappened, may have happened, or may happen.

So does polychronicity scale? Or is it a nested phenomenon whereby someone might be monochronic within hour- long intervals but polychronic when the frame enlarges to a month? And if so, what might be the consequences of different nesting combinations?

How do we understand such mosaictime in terms of striving for balance? Temporal units are rarely single-purpose and their boundaries and dependencies are often implicit. What sociotemporal values should we be honoring? How can we account for time that fits on neither side of a scale? How might scholarship rethink balance or efficiency with different forms of accounting, with attention to institutions as well as individuals?

Our rendering of porous time imagines a newperspective on time, in whichthe dominant temporal logic expandsbeyond ideals of control and mastery to include navigation(with or without conscious attention) of that which cannot be gridded or managed: the temporal trails, multiple interests, misaligned rhythms and expectations of others.

Taken together, an orientation to time as spectral, mosaic, rhythmic (dissonant),and obligatedsuggestsa possible alternate understanding of what time is and how it can work.An initial typology ofporous time honors the fluidity of time and its unexpected shifts; it also acknowledges novel integrations of time in everyday practice. Addressingthese alternate temporal realities allows us to build on CSCW’s legacy of related research to questionthereach and scope of thedominant temporal logic.

Yet, thepromise of social control affordedby information and communication technologies belies the inadequacy ofthe dominant temporal logic.

In contrast to the assumption oftime as linear, with ordered chunks progressing ina straightforward manner, people often negotiate time rhythmically, arranging timein patterns and tempos that do not always co-exist harmoniously. In line with earlier CSCW findings [e.g., 4, 9, 45, 46], we term thisrhythmic time, which acknowledges both the rhythmic nature of temporal experience as well a potential disorderliness or ‘dissonance’ when temporal rhythms conflict.Like mosaic time, bringing dissonant rhythms into semi-alignment requires adaptation, work, and patience.

In alignmentwith Reddy and Dourish’s concept of temporal trajectory [45], spectral time suggests that temporal experience is more than a grid of accountable blocks; multiple temporalities create flowsthat often defy both logical renderingand seamless manipulation

bels. To date, we have found that our subjects have a minimal ability, and almost no language, to discuss the vagaries of time. In general, people attempt to negotiate their subjective experiences of time through the assumptions of the dominant temporal logic outlined a

In witnessing how people struggle toorient to the dominant temporal logic,we find it isinsufficient to encapsulate temporal experiences. Thus, we now theorizea set of expanded notions, an initial typology that we call ‘porous time’.

One of the ways that a temporal logic becomesvisible for analysis and critique is through the tensions that emerge when its assumptions and norms do not align with daily experience. In our collective fieldwork we have observedmultiple examples of mundane dailypractices coming into conflict withthe logic that time is, or should be, chunk-able, singular purpose, linear, and/or owned.These tensionshelp bring to the fore the extent of the dominant temporal logic and showcase the inadequacy of this narrow set of assumptions to fully describetemporal experiences.

We call this prevailing temporal logic ‘circumscribed time.’ We use this label to highlight the underlying orientation to time as a resource that can, and should, be mastered. A circumscribed temporal logic infers that time should be harnessed into ‘productive’ capacity by approaching it as something that can be chunked, allocated to a single use, experienced linearly, and owned. In turn, the norms of society place the burden on individuals to manage and ‘balance’ time as a steward, optimizing this precious resource by way of control and active manipulation.

Finally,time is understood asaresource that is owned by an individual and thus needs to be managed and apportioned by that individual.Like personal income, time is a resource that the individual has both the burden and responsibility to manage well. This vision of time reflects an assumption there are ‘better’ or ‘worse’ ways to use, spend and save time and it is up to the individual to engage in practices of temporal ownership. Controlling time doesnot suggest thatan individual can speed up or slow down time, but rather,suggeststhat timecan be personally configured to meet individual aims or goals.

Thedominant temporal logicalso conceptualizestime aslinear. In other words,one chunk of time leads to another in a straight progression. While chunks of time can be manipulated and reordered in the course of a day (or week, or month), each chunk of time has a limited duration and each activity has a beginning and an end. An hour is an hour is an hour, and in the course of a day (or a lifetime) hours stack up like a vector, moving one forward in a straightforward progression.

Aligned with chunk-able time is the assumption that each chunk of time, or its particular gridded arrangement, is allocated to a single purpose.

appointment. Time chunksopen up the possibility for future-oriented temporal manipulation and valuation; they assumethat we are able to know, in advance, the duration of tasks and experiences.

The expectation that time is chunk-able is conditioned by an understanding that time exists in units (a second, a minute, a year) and that temporal units are equal–that can be swapped and exchanged with relative ease.

A temporal logicoperatesat multiple levels. It is perpetuated insocialand cultural discourse; is embedded in institutional expectations and policies; drivesthe design and implementation of technologies;establishes resilient social norms; and provides a cache of normative, rational examples to draw on when individuals needtomake sense of their everyday engagements with time. When a tool like Microsoft Outlook is designed, presented, and justified in a marketing campaign it is both reflecting and perpetuating atemporal logic.

In particular, by temporal logicwe mean the socially legitimated, shared assumptions about time that areembedded in institutional and societal norms, discourses, material and technological processes, and shared ideologies. A temporal logic defines what is rational, normal and expected, andimbues a society with a definitionof what time is that directsindividuals in how they should operate in and through time.It provides an understanding of time that becomes so embedded that it seems to define reality.

What would it look like to more explicitly acknowledge power dynamics in information and communication technologies? In the tradition of critical and reflective design [50], how might CSCW scholarship think about designing technologies that ‘protect’ users from temporal obligations and render messiness and disorganization a possible way of engaging with time?

Interrogating the temporal logic of circumscribed time raises three related sociotemporal concerns particularly relevant to CSCW: lived experience, visions of success, and power relations. We address each concernin relation to key theoretical works to showhow the insights presented here both point tothe limitations of the dominant temporal logic of circumscribed time and demandexpanding this logic to include those orientations suggested by porous time.

The temporal logic of circumscribed time falls short of describing, let alone organizing, the complex temporalities that govern American lives today. As an expansion of the dominant logic, porous time aims toprovide a more nuanced account of howtemporality shapes interactions among people, technologies, and the

implies the virtual inseparability of semantics from syntactics, and, indeed, Saussure's followers are often quite appropriately called structuralists, as they view signs not so much in terms of their substantive "content" as in terms of the ways in which they are formally related to other signs (i.e., in terms of the structure of the symbolic system to which they belong). More specifically, they tend to focus particularly on the formal relation of opposition or contrast, because, "in any semiological system, whatever distin- guishes one sign from the oth

Consequently, efforts to design for temporal experience must do more than simply build desirable temporal models into technologies.

In their view, time is both independent of and dependent on behaviour: temporal structures are produced and reproduced through everyday action, and these in turn shape the rhythm and form of ongoing practices. Existing temporal structures become taken for granted and appear to be unbending, but time is also treated as malleable in that temporal structures can be changed and new ones estab-lished. The objective/subjective dichotomy is not inherent to the nature of time, but is a property of the particular tem-poral structures being enacted at a particular moment. They call for a focus on examining how temporal structures be-come established for a particular activity, and how they are sustained, reinforced or modified in practice.

Designing for an alternative temporal experience means understanding the ways in which multiple temporali-ties intersect, whether these frame a person’s working day, or allow a family to spend time together. While scheduling technologies do of course have a role to play here [see e.g. 31], many of the temporal structures that frame everyday life are not so much scheduled as unfold in a way that isunremarkable [54], or are so firmly established that they are no longer seen as alterable.

sregarded. Temporal Design attempts to counteract these effects by drawing attention to social practices of time. Time is a social process, tacitly defined through everyday practices. It is rehearsed, learned, designed, created, storied, and made. This aspect however is often overlooked not only by designers, but also by society in general. Designers can have a key role in unlocking the hegemonic narratives that restrict cultural understandings of time and in opening up new ways of making, living and thinking

The aim was to challenge the idea that the world is in a state of constant acceleration by inviting children to reflect on the multiple speeds of their day. In contrast to the slow movement, which assumes acceleration as a universalised condition and attempts to counteract this condition by promoting opportunities to slow down, the intention here was to invite the students to explore the variant speeds at which they l

Temporal Design could thereforeinvolve:•Identifying dominant narratives, including the forces and infrastructures that sustain them or which they help to support;•Challenging these narratives, e.g. by revealing more nuanced expressions of time;•Drawing attention to alternative temporalities, their dynamics and significance;•Exposing networks of temporalities, so as to illustrate multiplicity and variety.The approach would bring several benefits:•Acknowledging that slow and fast rhythms co-occur and are often interdependent would challenge the assumption of universal acceleration,•Acknowledging that the times of some are more invested in than others, would enable challenges to temporal inequalities.•Acknowledging that the natural world has multiple rhythms would change the assumption that ittherefore provides a stable background for human-made ‘progress’(McKibben, 2008

LARISSA PSCHETZ, MICHELLE BASTIAN, CHRIS SPEED 6With this in mind we propose Temporal Design as a shift within design towards a pluralist perspectiveon time. Temporal Design attempts to identify and challenge expressions of dominant narratives of time, as it recognises that everyday rhythms are composed of multiple temporalities, whichare defined by both direct and indirect factors. It also seeks to empower alternative notions that are neglected by these narratives. It suggests that designers should start looking at time as something that emerges in relation to a complexity of cultural, social, economicand political forces.Temporal designers wouldtherefore observe time in the social context, investigating beyond narratives of a universal time and linear progression, and beyond simple dichotomies of fast and slow. This is not to simply negate dominant notions but acknowledging that they co-exist with several other expressions in all aspects of life. There is a multiplicity of temporalities latent in the world. Designers can help to create tools that disclose them, also revealing the intricacies of temporal relationships and negotiations that take place across individuals, groups, and institutions. They would then consider a network of times that accommodates the multiplicity of temporalities in the everyday, the natural world, and in intersections between these re

Despite a clear social motivation, the alternative approaches to time in design described above have been constrained by dominant narratives of time. Further they have often only considered time in terms of pace, direction and flow rather than the more complex ways that it is involved in social life (e.g. Gre

Thus in developing a theoretical framework which could support an understanding of time as multiple, heterogeneous and deeply entangled within various social formations (which may be discrete or overlapping), work in the social sciences, particularly anthropology and sociology, has proven to be more useful. Such approaches enable us to ask different questions about what time is and how it works. Rather than seeing time as a flow between past, present and future (whether this be linear or nonlinear), it becomes possible to ask how time operates as a system for social collaboration (Sorokin and Merton 1937), how it legitimates some and ‘manages’ others (Greenhouse 1996), or how it works within systems of exclusion (Fabian 1983). We thus move from time as flow to time as s

tries (Prado 2013). Here again, instead of looking at the present as a heterogeneous context, the present isconsidered as uniform and following a linear trajectory toward

Design has also taken a critical approach to time in its attempt to anticipate the impacts of present actions in the future, particularly those concerning the introduction of new technologies. This attitude may be generally identified in particular design projects but is most evident in speculative design movements such as Design Fictions, Critical Design and Design for Debate.Since design is often focused on yet-to-exist interventions in a given context, it is often said to be invariably future-oriented (e.g. in Dunne & Rab

evices. Similarly, Phoebe Sengers (2011) reflects on the way slower attitudes could be promoted by ‘‘making fewer choices, accessing less information, making productivity less central, keeping our lives less under formal control’’; she further considers how this attitude could be reflected in the design of communication technologies. Instead of reinforcing dichotomies, Fullerton (2010) and Sengers (2011) draw attention to practices that emphasise alternative expressions

The association of alternative approaches to time with a rejection of technology reinforces dichotomies that do not reflect the way people relate to artefacts and systems (Wajcman 2015). As a result, these proposals not only risk being interpreted as nostalgic or backward looking, but also leave little space for integrating more complex accounts of time (particularly those arising in the social sciences) or for discussing more nuanced rhythms, as well as more complex forces and consequences related to temporal decisions. As a result, instead of challenging dominant accounts of time, these proposals arguably reinforce the overarching narrative of universalised acceler

In Slow Technology, Hallnas & Redstrom (2001) advance the need for a form of design that emphasises reflection, the amplification of environments, and the use of technologies that a) amplify the presence of time; b) stretch time and extend processes; and c) reveal an expression of presenttime as slow-paced. Important here is the concept of “time presence”: “when we use a thing as an efficient tool, time disappears, i.e. we get things done. Accepting an invitation for reflection inherent in the design means on the other hand that time willappear, i.e. we open up for time presence” (Hallnas & Redstrom 2001). A slow technology would not disappear, but would make its

The information contained in the information system is notsufficient in itself; the temporal context within which it can be placed,organized according to the trajectory, helps makes sense of it.
