Journal articles on the topic 'Collins asymmetries'

In this contribution TMD evolution of azimuthal asymmetries, in particular of the Sivers and double Collins asymmetries, is addressed. A comparison of the scale dependence is made between asymmetries described with TMD factorization at low transverse momentum and those described with collinear factorization at high transverse momentum. Finally, the advantages of Bessel weighting are discussed: convergence of transverse momentum integrals, suppression of large transverse momentum contributions, and well-defined lattice QCD evaluations of Bessel-weighted TMDs including proper gauge links.

We present the preliminary results of the measurement of the azimuthal asymmetries of two charged pions in the inclusive process [Formula: see text] in the BESIII experiment. These asymmetries are attributed to the so-called Collins fragmentation function, which depict the behavior of a hadron produced from a transversely polarized quark. This spin-dependent function is an important input for the global analysis of extracting the transversity inside the nucleon. In addition, by comparison with the measured asymmetries at Belle, this measurement provides the first data to explore the [Formula: see text] evolution of the spin-dependent fragmentation function. This work is performed based on about 62[Formula: see text][Formula: see text] data collected with the BESIII detector at BEPCII at [Formula: see text]=3.65[Formula: see text]GeV.

Single spin asymmetry measurements ([Formula: see text]) of the azimuthal distribution of charged pions inside jets produced in transversely polarized proton collisions are sensitive to the transversity distribution and the Collins fragmentation function. The STAR Detector at the Relativistic Heavy Ion Collider is well suited for these types of measurements as it is capable of full jet reconstruction and charged pion identification in the mid-rapidity region ([Formula: see text][Formula: see text][Formula: see text][Formula: see text]). We report here the first observation of Collins [Formula: see text] asymmetries in [Formula: see text] GeV [Formula: see text] collisions.

In the fragmentation of a transversely polarized quark a left-right asymmetry, the Collins asymmetry, is expected for each hadron produced in the process [Formula: see text]. Similarly, an asymmetry is also expected for the hadron pair, the dihadron asymmetry. Both asymmetries have been measured to be different from zero on transversely polarised proton targets and have allowed for first extractions of the transversity distributions. From the high statistics COMPASS data we have further investigated these asymmetries getting strong indications that the two mechanisms are driven by a common physical process.

In this talk, we present our recent work about QCD evolution effect on the transverse momentum dependent(TMD) observables for collins asymmetries in e+e- annihilation to di-hadron and semi-inclusive deep inelastic scattering(SIDIS) processes, by taking into account TMD evolution effect is studied under CSS formalism. Our result shows the evolution effect will bring a significant correction to TMD distributions extracted form experiment data.

The large transverse single spin asymmetries (SSA) of high [Formula: see text] inclusive hadrons produced in polarized proton collisions are usually explained by means of collinear twist-3 multi-parton correlations. In this picture these asymmetries can originate from initial-state twist-3 parton distributions in the polarized proton and/or through the coupling between proton transversity and twist-3 fragmentation functions. The measurement of SSA for forward inclusive hadrons produced in [Formula: see text] collisions out to high transverse momentum helps to examine the validity and interplay of these initial- and final-state models. These models can be further explored by investigating the dependence of the SSA on event topologies. We present our latest status on the measurement of SSA for forward inclusive [Formula: see text] detected within [Formula: see text] in [Formula: see text] = 500 GeV [Formula: see text] collisions as well as its dependence on event topologies. We will also present our analysis of Sivers and Collins asymmetries for forward jet-like events consisting of multi-photon final states. The measurements are based on the data taken in 2011 with integrated luminosity [Formula: see text] 22 [Formula: see text].

The clean environment of the e+e- collisions provided by the B-factory PEP-II and the high performances of the BABAR detector allow for precise measurements of the properties of inclusive hadron production. We present recent results obtained using the full data sample of nearly 500 fb-1 on measurements of the inclusive light hadrons momentum spectra, and on anti-deuteron production from decays of bottomonium states, and from continuum e+e- annihilation. We also present a measurement of the azimuthal asymmetries induced by the Collins effect in inclusive production of pion pairs in e+e- → ππX annihilation, where the two pions are produced in opposite hemispheres.

COMPASS is a high-energy physics experiment operating at the SPS at CERN. Wide physics program of the experiment comprises study of hadron structure and spectroscopy with high energy muon and hadrons beams. As for the muon-program, one of the important objectives of the COMPASS experiment is the exploration of the transverse spin structure of the nucleon via spin (in)dependent azimuthal asymmetries in single-hadron production in deep inelastic scattering of polarized leptons off transversely polarized target. For this purpose a series of measurements were made in COMPASS, using 160 GeV/c longitudinally polarized muon beam and transversely polarized [Formula: see text] (in 2002, 2003 and 2004) and [Formula: see text] (in 2007 and 2010) targets. The experimental results obtained by COMPASS for unpolarized target azimuthal asymmetries, Sivers and Collins effects and other azimuthal observables play an important role in the general understanding of the three-dimensional nature of the nucleon. Giving access to the entire twsit-2 set of transverse momentum dependent parton distribution functions and fragmentation functions COMPASS data triggers constant theoretical interest and is being widely used in phenomenological analyses and global data fits. In this review main focus is given to the very recent results obtained by the COMPASS collaboration from first ever multi-dimensional extraction of transverse spin asymmetries.

Parton distribution functions, which represent the flavor and spin structure of the nucleon, provide invaluable information in illuminating quantum chromodynamics in the confinement region. Among various processes that measure such parton distribution functions, semi-inclusive deep inelastic scattering is regarded as one of the golden channels to access transverse momentum dependent parton distribution functions, which provide a 3D view of the nucleon structure in momentum space. The Jefferson Lab experiment E06-010 focuses on measuring the target single and double spin asymmetries in the [Formula: see text] reaction with a transversely polarized 3 He target in Hall A with a 5.89 GeV electron beam. A leading pion and the scattered electron are detected in coincidence by the left High-Resolution Spectrometer at 16° and the BigBite spectrometer at 30° beam right, respectively. The kinematic coverage concentrates in the valence quark region, x ~ 0.1–0.4, at Q2 ~ 1–3 GeV 2. The Collins and Sivers asymmetries of 3 He and neutron are extracted. In this review, an overview of the experiment and the final results are presented. Furthermore, an upcoming 12-GeV program with a large acceptance solenoidal device and the future possibilities at an electron–ion collider are discussed.

Abstract Over the last decade, theoretical and experimental engagement of transverse-spin phenomena has unlocked tantalizing opportunities for new insights into nucleon structure and hadronization. Observables such as hadrons in jets and dihadron correlations from polarized proton collisions provide access to the transversity distribution function at a range of x complementary to existing semi-inclusive deep inelastic scattering (SIDIS) experiments but at a much higher range of Q 2. Moreover, these two observables give access through two different factorization frameworks–transverse-momentum-dependent (TMD) and collinear–enabling a unique path to address questions concerning factorization-breaking and the universality of TMD functions. Data collected by STAR have revealed the first observations of transverse single-spin asymmetries in the azimuthal distributions of dihadron correlations and hadrons within jets from polarized proton collisions at both s = 500 GeV and 200 GeV. The STAR 200 GeV dihadron data have recently been included in global analyses that for the first time include SIDIS, e + e −, and p + p data to extract the transversity distribution. The STAR hadron-in-jet data provide a unique opportunity to illuminate longstanding questions: Do factorization and universality extend to the TMD picture in proton-proton collisions, e.g. through the Collins mechanism? How do TMD functions evolve with changing kinematics? The STAR dihadron and hadron-in-jet data will be presented and discussed in context with the recent global analyses and model calculations.

Although the hearing loss of patients with Treacher Collins syndrome is well documented, few studies have reported jointly on their hearing loss and ear pathology. This paper reports on the hearing loss and computerized tomography (CT) assessments of ear malformations in a large pediatric series of patients with Treacher Collins. Of the 29 subjects assessed by the Craniofacial Program between 1986 and 1990, paired audiologic and complete CT assessments were available for 23 subjects. The external ear canal abnormalities were largely symmetric, either bilaterally stenotic or atretic. In most cases, the middle ear cavity was bilaterally hypoplastic and dysmorphic, and ossicles were symmetrically dysmorphic or missing. Inner ear structures were normal in all patients. The majority of patients had a unilateral or bilateral moderate or greater degree of hearing loss and almost half had an asymmetric hearing loss. The hearing loss of all subjects was conductive, except for three whose loss was bilateral mixed. Two types of bilaterally symmetric hearing loss configurations, flat and reverse sloping, were noted. Conductive hearing loss in patients with Treacher Collins is mainly attributable to their middle ear malformations, which are similar for those of patients with malformed or missing ossicles.

ABSTRACT Basu (1997) proposes a measure of financial reporting conservatism based on asymmetry in the conditional earnings/returns relation. Patatoukas and Thomas (2011) show upward bias in this measure, because a placebo—lagged earnings—also exhibits similar asymmetry. Ball, Kothari, and Nikolaev (2013a) and Collins, Hribar, and Tian (2014) propose alternative explanations for the bias and offer revised measures to overcome the bias. However, we find that both revised measures remain substantially upward-biased. In particular, a placebo based on lagged share price mimics time-series and cross-sectional variation observed for the revised measures. More generally, we find biases in the asymmetric timeliness specification because earnings, accruals, and other measures of performance are often related to second and higher moments of the distribution of returns. In addition to suggesting that the asymmetric timeliness specification be used with caution, our study illustrates the useful role placebos can play in archival studies.

Статтю присвячено спробі дослідити двомовний ментальний лексикон. Головне питання дослідження – встановити, чи персько-англійські білінгви можуть досягнути ефекту семантичного / асоціативного або перекладацького праймінгу. Для відповіді на це питання було застосовано масковану праймінгову парадигму як техніку, що відображає автоматичні когнітивні процеси, що тривають під час семантичної обробки, а не стратегічного використання прайму. Із метою вирішення лексичного завдання було сформовано чотири типи цільових пар праймінгу (перекладацькі еквіваленти, семантично подібні, асоціативно та семантично пов’язані пари). Загалом у дослідженні взяло участь 85 персько-англійських білінгвів. Хоча ефекту праймінгу не було виявлено для перших трьох груп, респонденти із семантично пов’язаних пар (найміцніше пов’язаних слів) відповіли приблизно на 29 мс швидше. Результати засвідчили, що білінгви мають спільні уявлення для асоціативних семантично пов’язаних слів. Отже, навчання новим словам другої мови, шляхом поєднання їх із асоціативно пов’язаними словами першої мови, може привести до кращих результатів. Література References Balota, D. A., & Lorch, R. F.

In this article, we analyse the impact of the introduction of options on an investment portfolio. Our first objective is to derive closed-form formulae for the standard measures of portfolio efficiency: risk premium, risk, Sharpe ratio, and beta, of any portfolio containing any combination of options. Using these formulae on three examples of simple option strategies (call overwriting, put protection, and collars), we show how these statistics are altered by the inclusion of an option overlay in a portfolio. Our second objective is to show that if an option strategy is repeated over multiple investment time periods, the long-run return becomes normally distributed. Our motivation is to provide investors with the mathematics to measure the impact of the introduction of options on portfolio efficiency and encourage a potential portfolio rebalance to account for this impact. Then, we highlight that whilst options can create asymmetric non-normal outcomes, their repeated use may not alter the long-run portfolio return in the desired way and thus to encourage investors to assess if an option overlay will deliver the desired long-run outcome.

The production of vector mesons in SIDIS is a particularly interesting channel to study the polarized fragmentation and related phenomena. Preliminary COMPASS results for the first measurement of inclusive \rho^0ρ0 Collins and Sivers transverse-spin asymmetries are presented here for the first time. The analysis is based on the data-set collected by COMPASS in 2010 using a 160 GeV/c \mu^+μ+ beam and a transversely polarized NH_3NH3 target. The asymmetries are extracted as function of Bjorken-x, of the total transverse momentum of the oppositely charged hadron pair and of the fraction of available energy z carried by the pair. Indications for positive Collins and Sivers asymmetries are obtained as expected from models.

A comprehensive set of azimuthal single-spin and double-spin asymmetries in semi-inclusive leptoproduction of pions, charged kaons, protons, and antiprotons from transversely polarized protons is presented. These asymmetries include the previously published HERMES results on Collins and Sivers asymmetries, the analysis of which has been extended to include protons and antiprotons and also to an extraction in a three-dimensional kinematic binning and enlarged phase space. They are complemented by corresponding results for the remaining single-spin and double-spin asymmetries for transverse target-polarization orientation.

A new method is suggested for the extraction of uu-quark and dd-quark transversity distributions, using single spin asymmetry (SSA) data in semi-inclusive deep inelastic scattering (SIDIS) processes, where they couple to the Collins or the di-hadron fragmentation functions. We discuss a recent suggestion to extract the transversity distribution using the concept of difference asymmetries and their ratios, which avoids the requirement of Collins function. We suggest new measurements, involving ratios of polarized cross-sections, that would directly probe the ratio h_1^{d_v}/h_1^{u_v}h1dv/h1uv. We also show some numerical estimates.

Aim:Treacher Collins syndrome is a rare congenital disorder of craniofacial development with a highly variable pheonotype. This syndrome occurs with an incidence of 1:50,000, and more than 60% of the cases have no previous family history and arise as the result of de novo mutations. The disorder displays an intricate underlying dysmorphology. Affected patients may suffer life-threatening airway complications and functional difficulties involving sight, hearing, speech, and feeding. Deformation of facial structures produces a characteristic appearance that includes malar-zygomatic hypoplasia, periorbital soft tissue anomalies, maxillomandibular hypoplasia, and ear anomalies. Management requires a specialized craniofacial team, as comprehensive care starts at birth and may require life-long follow-up. Standard craniofacial procedures for bony and soft tissue reconstruction are used. This article outlines current treatment strategies and future concepts for surgical and regenerative management. Methods:The new field of regenerative medicine and therapy offers the promise to improve some of these treatments. In particular, Structural Fat Grafting (lipostructure) seems to be a good strategy to restore the normal volume and contour of the face, and to provide a source of adipose-derived stem cells (ADSCs) with a multilineage differentiation potential. In this work, we present the case of a young girl with Treacher Collins Syndrome who underwent serial sessions of fat grafting in addition to other surgical bony reconstructive techniques. ADSCs have been isolated from the patient’s lipoaspirate, and compared for their stemness properties with those of a healthy subject. Conclusion:Screening of the genome of the Treacher Collins patient using array-Comparative Genomic Hybridization (array-CGH) allowed us to identify some chromosomal imbalances that are probably associated with the syndrome.Correction of these imbalances and asymmetries by modulating ADSCs could be an innovative approach to improve and stabilize the results of the surgical treatment of Treacher Collin Syndrome.

At the leading twist, the transversity distribution function, h^{q}_{1}(x)h1q(x), where xx is the longitudinal momentum fraction of the proton carried by quark qq, encodes the transverse spin structure of the nucleon. Extraction of it is difficult because of its chiral-odd nature. In transversely polarized proton-proton collisions (p^\uparrow pp↑p), h_{1}^{q}(x)h1q(x) can be coupled with another chiral-odd partner, a spin-dependent fragmentation function (FF). The resulting asymmetries in hadron(s) azimuthal correlations directly probe h_{1}^{q}(x)h1q(x). We report the measurement of correlation asymmetries for charged pion(s) in p^\uparrow pp↑p, through the Collins and the Interference FF channel.

Abstract A comprehensive set of azimuthal single-spin and double-spin asymmetries in semi-inclusive leptoproduction of pions, charged kaons, protons, and antiprotons from transversely polarized protons is presented. These asymmetries include the previously published HERMES results on Collins and Sivers asymmetries, the analysis of which has been extended to include protons and antiprotons and also to an extraction in a three-dimensional kinematic binning and enlarged phase space. They are complemented by corresponding results for the remaining four single-spin and four double-spin asymmetries allowed in the one-photon-exchange approximation of the semi-inclusive deep-inelastic scattering process for target-polarization orientation perpendicular to the direction of the incoming lepton beam. Among those results, significant non-vanishing cos (ϕ−ϕS) modulations provide evidence for a sizable worm-gear (II) distribution, $$ {g}_{1\mathrm{T}}^q\left(x,{\mathrm{p}}_T^2\right) $$ g 1 T q x p T 2 . Most of the other modulations are found to be consistent with zero with the notable exception of large sin (ϕS) modulations for charged pions and K+.

Abstract We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent parton distributions. We demonstrate how the QED contributions can be well approximated by collinear factorization, and illustrate the application of the factorized approach to QED radiation in inclusive scattering. For semi-inclusive processes, we show how radiation effects prevent a well-defined “photon-nucleon” frame, forcing one to use a two-step process to account for the radiation. We illustrate the utility of the new method by explicit application to the spin-dependent Sivers and Collins asymmetries.

It has been suggested that a colour-entanglement effect exists in the Drell-Yan cross section for the ‘double T-odd’ contributions at low transverse momentum \bm{Q_\st}, rendering the colour structure different from that predicted by the usual factorisation formula . These T-odd contributions can come from the Boer-Mulders or Sivers transverse momentum dependent distribution functions. The different colour structure should be visible already at the lowest possible order that gives a contribution to the double Boer-Mulders (dBM) or double Sivers (dS) effect, that is at the level of two gluon exchanges. To discriminate between the different predictions, we compute the leading-power contribution to the low-\bm{Q_\st} dBM cross section at the two-gluon exchange order in the context of a spectator model. The computation is performed using a method of regions analysis with Collins subtraction terms implemented. The results conform with the predictions of the factorisation formula. In the cancellation of the colour entanglement, diagrams containing the three-gluon vertex are essential. Furthermore, the Glauber region turns out to play an important role – in fact, it is possible to assign the full contribution to the dBM cross section at the given order to the region in which the two gluons have Glauber scaling. A similar disentanglement of colour is found for the dS effect.

Abstract In this study, the effect of collar shape and its alignment on reducing scour depth in the front part of the structure, with the pier under clear water conditions, was investigated to determine changes in the flow pattern around the structure. The collars were examined in two asymmetrical shapes with dimensions of and at three levels of installation relative to the bed: bed level, 1 and 2 cm above the bed. The results revealed that the presence of the collar not only reduced the ultimate scouring depth but also delayed the formation of the scouring hole. This impact was observed to be greater as the size of the collar increased. In addition, reducing the alignment of the collars can lead to better performance of the collar and its efficiency in the cost of the design. Therefore, collars installed on the bed surface indicated good performance in controlling scour. On the other hand, once the flow characteristics around the bridge pier with and without collar were examined, it was determined that affecting the downstream flow reduces the strength of the vortices and changes the reciprocating behavior and the displacement of the vortices.

Sequences of high Bragg-angle (0 B = 74°) double-crystal X-ray topographs taken at the SRS (Daresbury, U.K.) have yielded precise measurements of lattice parameter differences between growth sectors of different crystallographic forms in a large undoped synthetic diamond whose type Ib infrared absorption spectrum (principal peak at 1130 cm -1 ) indicated atomically dispersed nitrogen, singly substituting for carbon, as the only detectable impurity. The plate-shaped specimen, polished parallel to (110), 5.0 x 3.2 mm 2 in area, 0.7 mm thick, possessed an unusually well developed (110) growth sector containing nitrogen impurity concentration of only ca. 10 -6 , which served as an internal standard of pure-diamond lattice parameter with which lattice parameters of nitrogen-containing growth sectors were compared. The specimen’s suitability for precision diffractometry was checked by comprehensive tests using optical microscope techniques, cathodoluminescence and single-crystal X-ray topography. The double-crystal combination was silicon reference crystal, asymmetric 175 reflection, with diamond specimen symmetrical 440 reflection. The principal measurement was the increase of the lattice parameter, a 0 , of the (111) growth sector (nitrogen content 88 + 7 parts per 10 6 atomic) relative to that of the (110) sector: Aa 0 / a 0 = 1.18 + 0.07 x 10 -5 . In terms of measured infrared absorption coefficient at 1130 cm -1 , this gives Aa 0/a 0 = (2.95 + 0.27) x 10 -6 [p(1130 cm -1 )/cm -1 ], which is believed to hold for growth sectors of all crystallographic forms. Combination with the nitrogen assay findings of Woods, van Wyk & Collins ( Phil. Mag. B 62. 589-595 (1990)) provides a direct relation to c N , the fractional atomic concentration of substitutional nitrogen, as A a 0 / a 0 = (0.14 + 0.02) c N , which indicates that the effective volume of a single substitutional nitrogen atom in diamond is 1.41 +0.06 times that of the carbon atom it replaces. This substantial dilatation conflicts with several models for the substitutional nitrogen structure.

IntroductionAccounts of mentoring relationships inevitably draw attention to hierarchies of expertise, knowledge and learning. While public concerns about both the risks and benefits for young people of social media, little attention has been given to the nature of the mentoring role that parents and families play alongside of schools. This conceptual paper explores models of mentorship in the context of family dynamics as they are affected by social media use. This is a context that explicitly disrupts hierarchical structures of mentoring in that new media, and particularly social media use, tends to be driven by youth cultural practices, identity formation, experimentation and autonomy-seeking practices (see for example: Robards; boyd; Campos-Holland et al.; Hodkinson). A growing body of research supports the notion that young people are more skilled in navigating social media platforms than their parents (FOSI; Campos-Holland et al.). This research establishes that uncertainty and tension derived from parents’ impression that their children know more about social media they do (FOSI; Sorbring) has brought about a market for advice and educational programs. In the content of this paper it is notable that when family dynamics and young people’s social media use are addressed through notions of digital citizenship or cyber safety programs, a hierarchical mentorship is assumed, but also problematised; thus the expertise hierarchy is inverted. This paper argues that use of social media platforms, networks, and digital devices challenges traditional hierarchies of expertise in family environments. Family members, parents and children in particular, are involved in ongoing, complex conversations and negotiations about expertise in relation to technology and social media use. These negotiations open up an alternative space for mentorship, challenging traditional roles and suggesting the need for cooperative processes. And this, in turn, can inspire new ways of relating with and through social media and mobile technologies within the family.Inverting Expertise: Social Media, Family and MentoringSocial media are deeply embedded in everyday routines for the vast majority of the population. The emergence of the ‘networked society’, characterised by increasing and pervasive digital and social connectivity, has the potential to create new forms of social interactions within and across networks (Rainie and Wellman), but also to reconfigure intergenerational and family relations. In this way, social media introduces new power asymmetries that affect family dynamics and in particular relationships between young people and their parents. This relatively new mediated environment, by default, exposes young people to social contexts well beyond family and immediate peers making their lived experiences individual, situational and contextual (Swist et al.). The perceived risks this introduces can provoke tensions within families looking to manage those uncertain social contexts, in the process problematising traditional structures of mentorship. Mentoring is a practice predominantly understood within educational and professional workplace settings (Ambrosetti and Dekkers). Although different definitions can be found across disciplines, most models position a mentor as a more experienced knowledge holder, implying a hierarchical relationship between a mentor and mentee (Ambrosetti and Dekkers). Stereotypically, a mentor is understood to be older, wiser and more experienced, while a mentee is, in turn, younger and in need of guidance – a protégé. Alternative models of mentorship see mentoring as a reciprocal process (Eby, Rhodes and Allen; Naweed and Ambrosetti).This “reciprocal” perspective on mentorship recognises the opportunity both sides in the process have to contribute and benefit from the relationship. However, in situations where one party in the relationship does not have the expected knowledge, skills or confidence, this reciprocity becomes more difficult. Thus, as an alternative, asymmetrical or cooperative mentorship lies between the hierarchical and reciprocal (Naweed and Ambrosetti). It suggests that the more experienced side (whichever it is) takes a lead while mentoring is negotiated in a way that meets both sides’ needs. The parent-child relationship is generally understood in hierarchical terms. Traditionally, parents are considered to be mentors for their children, particularly in acquiring new skills and facilitating transitions towards adult life. Such perspectives on parent-child relationships are based on a “deficit” approach to youth, “whereby young people are situated as citizens-in-the-making” (Collin). Social media further problematises the hierarchical dynamic with the role of knowledge holder varying between and within the family members. In many contemporary mediated households, across developed and wealthy nations, technologically savvy children are actively tailoring their own childhoods. This is a context that requires a reconceptualisation of traditional mentoring models within the family context and recognition of each stakeholder’s expertise, knowledge and agency – a position that is markedly at odds with traditional deficit models. Negotiating Social Media Use within the FamilyIn the early stages of the internet and social media research, a generational gap was often at the centre of debates. Although highly contested, Prensky’s metaphor of digital natives and digital immigrants persists in both the popular media and academic literature. This paradigm portrays young people as tech savvy in contrast with their parents. However, such assumptions are rarely grounded in empirical evidence (Hargittai). Nonetheless, while parents are active users of social media, they find it difficult to negotiate social media use with their children (Sorbring). Some studies suggest that parental concerns arise from impressions that their children know more about social media than they do (FOSI; Wang, Bianchi and Raley). Additionally, parental concern with a child’s social media use is positively correlated with the child’s age; parents of older children are less confident in their skills and believe that their child is more digitally skillful (FOSI). However, it may be more productive to understand social media expertise within the family as shared: intermittently fluctuating between parents and children. In developed and wealthy countries, children are already using digital media by the age of five and throughout their pre-teen years predominantly for play and learning, and as teenagers they are almost universally avid social media users (Nansen; Nansen et al.; Swist et al.). Smartphone ownership has increased significantly among young people in Australia, reaching almost 80% in 2015, a proportion nearly identical to the adult population (Australian Communications and Media Authority). In addition, most young people are using multiple devices switching between them according to where, when and with whom they connect (Australian Communications and Media Authority). The locations of internet use have also diversified. While the home remains the most common site, young people make use of mobile devices to access the internet at school, friend’s homes, and via public Wi-Fi hotspots (Australian Communications and Media Authority). As a result, social media access and engagement has become more frequent and personalised and tied to processes of socialisation and well-being (Sorbring; Swist et al.). These developments have been rapid, introducing asymmetry into the parent-child mentoring dynamic along with family tensions about rules, norms and behaviours of media use. Negotiating an appropriate balance between emerging autonomy and parental oversight has always featured as a primary parenting challenge and social media seem to have introduced a new dimension in this context. A 2016 Pew report on parents, teens, and digital monitoring reveals that social media use has become central to the establishment of family rules and disciplinary practices, with over two thirds of parents reporting the use of “digital grounding” as punishment (Pew). As well as restricting social media use, the majority of parents report limiting the amount of time and times of day their children can be online. Interestingly, while parents engage in a variety of hands-on approaches to monitoring and regulating children’s social media use, they are less likely to use monitoring software, blocking/filtering online content, tracking locations and the like (Pew). These findings suggest that parents may lack confidence in technology-based restrictions or prefer pro-active, family based approaches involving discussion about appropriate social media use. This presents an opportunity to explore how social media produces new forms of parent-child relationships that might be best understood through the lens of cooperative models of mentorship. Digital Parenting: Technological and Pedagogical Interventions Parents along with educators and policy makers are looking for technological solutions to the knowledge gap, whether perceived or real, associated with concerns regarding young people’s social media use. Likewise, technology and social media companies are rushing to develop and sell advice, safety filters and resources of all kinds to meet such parental needs (Clark; McCosker). This relatively under-researched field requires further exploration and dissociation from the discourse of risk and fear (Livingstone). Furthermore, in order to develop opportunities modelled on concepts of cooperative mentoring, such programs and interventions need to move away from hierarchical assumptions about the nature of expertise within family contexts. As Collin and Swist point out, online campaigns aimed at addressing young people and children’s safety and wellbeing “are often still designed by adult ‘experts’” (Collin and Swist). A cooperative mentoring approach within family contexts would align with recent use of co-design or participatory design within social and health research and policy (Collin and Swist). In order to think through the potential of cooperative mentorship approaches in relation to social media use within the family, we examine some of the digital resources available to parents.Prominent US cyber safety and digital citizenship program Cyberwise is a commercial website founded by Diana Graber and Cynthia Lieberman, with connections to Verizon Wireless, Google and iKeepSafe among many other partnerships. In addition to learning resources around topics like “Being a Responsible Citizen of the Digital World”, Cyberwise offers online and face to face workshops on “cyber civics” in California, emphasising critical thinking, ethical discussion and decision making about digital media issues. The organisation aims to educate and support parents and teachers in their endeavor to guide young people in civil and safe social media use. CyberWise’s slogan “No grown up left behind!”, and its program of support and education is underpinned by and maintains the notion of adults as lacking expertise and lagging behind young people in digital literacy and social media skills. In the process, it introduces an additional level of expertise in the cyber safety expert and software-based interventions. Through a number of software partners, CyberWise provides a suite of tools that offer parents some control in preventing cyberbullying and establishing norms for cyber safety. For example, Frienedy is a dedicated social media platform that fosters a more private mode of networking for closed groups of mutually known people. It enables users to control completely what they share and with whom they share it. The tool does not introduce any explicit parental monitoring mechanisms, but seeks to impose an exclusive online environment divested of broader social influences and risks – an environment in which parents can “introduce kids to social media on their terms when they are ready”. Although Frienedy does not explicitly present itself as a monitoring tool, it does perpetuate hierarchical forms of mentorship and control for parents. On the other hand, PocketGuardian is a parental monitoring service for tracking children’s social media use, with an explicit emphasis on parental control: “Parents receive notification when cyberbullying or sexting is detected, plus resources to start a conversation with their child without intruding child’s privacy” (the software notifies parents when it detects an issue but without disclosing the content). The tool promotes its ability to step in on behalf of parents, removing “the task of manually inspecting your child's device and accounts”. The software claims that it analyses the content rather than merely catching “keywords” in its detection algorithms. Obviously, tools such as PocketGuardian reflect a hierarchical mentorship model (and recognise the expertise asymmetry) by imposing technological controls. The software, in a way, fosters a fear of expertise deficiency, while enabling technological controls to reassert the parent-child hierarchy. A different approach is exemplified by the Australian based Young and Well Cooperative Research Centre, a “living lab” experiment – this is an overt attempt to reverse deliberate asymmetry. This pedagogical intervention, initially taking the form of an research project, involved four young people designing and delivering a three-hour workshop on social networking and cyber safety for adult participants (Third et al.). The central aim was to disrupt the traditional way adults and young people relate to each other in relation to social media and technology use and attempted to support learning by reversing traditional roles of adult teacher and young student. In this way ‘a non-hierarchical space of intergenerational learning’ was created (Third et al.). The result was to create a setting where intergenerational conversation helped to demystify social media and technology, generate familiarity with sites, improve adult’s understanding of when they should assist young people, and deliver agency and self-efficacy for the young people involved (7-8). In this way, young people’s expertise was acknowledged as a reflection of a cooperative or asymmetrical mentoring relationship in which adult’s guidance and support could also play a part. These lessons have been applied and developed further through a participatory design approach to producing apps and tools such as Appreciate-a-mate (Collin and Swist). In that project “the inclusion of young people’s contexts became a way of activating and sustaining attachments in regard to the campaign’s future use”(313).In stark contrast to the CyberWise tools, the cooperative mentoring (or participatory design) approach, exemplified in this second example, has multiple positive outcomes: first it demystifies social media use and increases understanding of the role it plays in young people’s (and adults’) lives. Second, it increases adults’ familiarity and comfort in navigating their children’s social media use. Finally, for the young people involved, it supports a sense of achievement and acknowledges their expertise and agency. To build sustainability into these processes, we would argue that it is important to look at the family context and cooperative mentorship as an additional point of intervention. Understood in this sense, cooperative and asymmetrical mentoring between a parent and child echoes an authoritative parenting style which is proven to have the best outcome for children (Baumrind), but in a way that accommodates young people’s technology expertise.Both programs analysed target adults (parents) as less skilful than young people (their children) in relation to social media use. However, while first case study, the technology based interventions endorses hierarchical model, the Living Lab example (a pedagogical intervention) attempts to create an environment without hierarchical obstacles to learning and knowledge exchange. Although the parent-child relationship is indubitably characterised by the hierarchy to some extent, it also assumes continuous negotiation and role fluctuation. A continuous process, negotiation intensifies as children age and transition to more independent media use. In the current digital environment, this negotiation is often facilitated (or even led) by social media platforms as additional agents in the process. Unarguably, digital parenting might implicate both technological and pedagogical interventions; however, there should be a dialogue between the two. Without presumed expertise roles, non-hierarchical, cooperative environment for negotiating social media use can be developed. Cooperative mentorship, as a concept, offers an opportunity to connect research and practice through participatory design and it deserves further consideration.ConclusionsPrevailing approaches to cyber safety education tend to focus on risk management and in doing so, they maintain hierarchical forms of parental control. Adhering to such methods fails to acknowledge young people’s expertise and further deepens generational misunderstanding over social media use. Rather than insisting on hierarchical and traditional roles, there is a need to recognise and leverage asymmetrical expertise within the family in regards to social media.Cooperative and asymmetrical mentorship happens naturally in the family and can be facilitated by and through social media. The inverted hierarchy of expertise we have described here puts both parents and children, in a position of constant negotiation over social media use. This negotiation is complex, relational, unpredictable, open toward emergent possibilities and often intensive. Unquestionably, it is clear that social media provides opportunities for negotiation over, and inversion of, traditional family roles. Whether this inversion of expertise is real or only perceived, however, deserves further investigation. This article formulates some of the conceptual groundwork for an empirical study of family dynamics in relation to social media use and rulemaking. The study aims to continue to probe the positive potential of cooperative and asymmetrical mentorship and participatory design concepts and practices. The idea of cooperative mentorship does not necessarily provide a universal solution to how families negotiate social media use, but it does provide a new lens through which this dynamic can be observed. Clearly family dynamics, and the parent-child relationship, in particular, can play a vital part in supporting effective digital citizenship and wellbeing processes. Learning about this spontaneous and natural process of family negotiations might equip us with tools to inform policy and practices that can help parents and children to collaboratively create ‘a networked world in which they all want to live’ (boyd).

“Journalists have to begin a new type of journalism, sometimes being the guide on the side of the civic conversation as well as the filter and gatekeeper.” (Kolodzy 218) “In many respects, citizen journalism is simply public journalism removed from the journalism profession.” (Barlow 181) 1. Citizen Journalism — The Latest Innovation? New Media theorists such as Dan Gillmor, Henry Jenkins, Jay Rosen and Jeff Howe have recently touted Citizen Journalism (CJ) as the latest innovation in 21st century journalism. “Participatory journalism” and “user-driven journalism” are other terms to describe CJ, which its proponents argue is a disruptive innovation (Christensen) to the agenda-setting media institutions, news values and “objective” reportage. In this essay I offer a “contrarian” view, informed by two perspectives: (1) a three-stage model of theory-building (Carlile & Christensen) to evaluate the claims made about CJ; and (2) self-reflexive research insights (Etherington) from editing the US-based news site Disinformation between November 1999 and February 2008. New media theories can potentially create “cognitive dissonance” (Festinger) when their explanations of CJ practices are compared with what actually happens (Feyerabend). First I summarise Carlile & Christensen’s model and the dangers of “bad theory” (Ghoshal). Next I consider several problems in new media theories about CJ: the notion of ‘citizen’, new media populism, parallels in event-driven and civic journalism, and mergers and acquisitions. Two ‘self-reflexive’ issues are considered: ‘pro-ams’ or ‘professional amateurs’ as a challenge to professional journalists, and CJ’s deployment in new media operations and production environments. Finally, some exploratory questions are offered for future researchers. 2. An Evaluative Framework for New Media Theories on Citizen Journalism Paul Carlile and Clayton M. Christensen’s model offers one framework with which to evaluate new media theories on CJ. This framework is used below to highlight select issues and gaps in CJ’s current frameworks and theories. Carlile & Christensen suggest that robust theory-building emerges via three stages: Descriptive, Categorisation and Normative (Carlile & Christensen). There are three sub-stages in Descriptive theory-building; namely, the observation of phenomena, inductive classification into schemas and taxonomies, and correlative relationships to develop models (Carlile & Christensen 2-5). Once causation is established, Normative theory evolves through deductive logic which is subject to Kuhnian paradigm shifts and Popperian falsifiability (Carlile & Christensen 6). Its proponents situate CJ as a Categorisation or new journalism agenda that poses a Normative challenged and Kuhnian paradigm shift to traditional journalism. Existing CJ theories jump from the Descriptive phase of observations like “smart mobs” in Japanese youth subcultures (Rheingold) to make broad claims for Categorisation such as that IndyMedia, blogs and wiki publishing systems as new media alternatives to traditional media. CJ theories then underpin normative beliefs, values and worldviews. Correlative relationships are also used to differentiate CJ from the demand side of microeconomic analysis, from the top-down editorial models of traditional media outlets, and to adopt a vanguard stance. To support this, CJ proponents cite research on emergent collective behaviour such as the “wisdom of crowds” hypothesis (Surowiecki) or peer-to-peer network “swarms” (Pesce) to provide scientific justification for their Normative theories. However, further evaluative research is needed for three reasons: the emergent collective behaviour hypothesis may not actually inform CJ practices, existing theories may have “correlation not cause” errors, and the link may be due to citation network effects between CJ theorists. Collectively, this research base also frames CJ as an “ought to” Categorisation and then proceeds to Normative theory-building (Carlile & Christensen 7). However, I argue below that this Categorisation may be premature: its observations and correlative relationships might reinforce a ‘weak’ Normative theory with limited generalisation. CJ proponents seem to imply that it can be applied anywhere and under any condition—a “statement of causality” that almost makes it a fad (Carlile & Christensen 8). CJ that relies on Classification and Normative claims will be problematic without a strong grounding in Descriptive observation. To understand what’s potentially at stake for CJ’s future consider the consider the parallel debate about curricula renewal for the Masters of Business Administration in the wake of high-profile corporate collapses such as Enron, Worldcom, HIH and OneTel. The MBA evolved as a sociological and institutional construct to justify management as a profession that is codified, differentiated and has entry barriers (Khurana). This process might partly explain the pushback that some media professionals have to CJ as one alternative. MBA programs faced criticism if they had student cohorts with little business know-how or experiential learning (Mintzberg). Enron’s collapse illustrated the ethical dilemmas and unintended consequences that occurred when “bad theories” were implemented (Ghoshal). Professional journalists are aware of this: MBA-educated managers challenged the “craft” tradition in the early 1980s (Underwood). This meant that journalism’s ‘self-image’ (Morgan; Smith) is intertwined with managerial anxieties about media conglomerates in highly competitive markets. Ironically, as noted below, Citizen Journalists who adopt a vanguard position vis-a-vis media professionals step into a more complex game with other players. However, current theories have a naïve idealism about CJ’s promise of normative social change in the face of Machiavellian agency in business, the media and politics. 3. Citizen Who? Who is the “citizen” in CJ? What is their self-awareness as a political agent? CJ proponents who use the ‘self-image’ of ‘citizen’ draw on observations from the participatory vision of open source software, peer-to-peer networks, and case studies such as Howard Dean’s 2004 bid for the Democrat Party nominee in the US Presidential election campaign (Trippi). Recent theorists note Alexander Hamilton’s tradition of civic activism (Barlow 178) which links contemporary bloggers with the Federalist Papers and early newspaper pamphlets. One unsurfaced assumption in these observations and correlations is that most bloggers will adopt a coherent political philosophy as informed citizens: a variation on Lockean utilitarianism, Rawlsian liberalism or Nader consumer activism. To date there is little discussion about how political philosophy could deepen CJ’s ‘self-image’: how to critically evaluate sources, audit and investigation processes, or strategies to deal with elites, deterrence and power. For example, although bloggers kept Valerie Plame’s ‘outing’ as a covert intelligence operative highly visible in the issues-attention cycle, it was agenda-setting media like The New York Times who the Bush Administration targeted to silence (Pearlstine). To be viable, CJ needs to evolve beyond a new media populism, perhaps into a constructivist model of agency, norms and social change (Finnemore). 4. Citizen Journalism as New Media Populism Several “precursor trends” foreshadowed CJ notably the mid-1990s interest in “cool-hunting” by new media analysts and subculture marketeers (Gibson; Gladwell). Whilst this audience focus waned with the 1995-2000 dotcom bubble it resurfaced in CJ and publisher Tim O’Reilly’s Web 2.0 vision. Thus, CJ might be viewed as new media populism that has flourished with the Web 2.0 boom. Yet if the boom becomes a macroeconomic bubble (Gross; Spar) then CJ could be written off as a “silver bullet” that ultimately failed to deliver on its promises (Brooks, Jr.). The reputations of uncritical proponents who adopted a “true believer” stance would also be damaged (Hoffer). This risk is evident if CJ is compared with a parallel trend that shares its audience focus and populist view: day traders and technical analysts who speculate on financial markets. This parallel trend provides an alternative discipline in which the populism surfaced in an earlier form (Carlile & Christensen 12). Fidelity’s Peter Lynch argues that stock pickers can use their Main Street knowledge to beat Wall Street by exploiting information asymmetries (Lynch & Rothchild). Yet Lynch’s examples came from the mid-1970s to early 1980s when indexed mutual fund strategies worked, before deregulation and macroeconomic volatility. A change in the Web 2.0 boom might similarly trigger a reconsideration of Citizen Journalism. Hedge fund maven Victor Niederhoffer contends that investors who rely on technical analysis are practicing a Comtean religion (Niederhoffer & Kenner 72-74) instead of Efficient Market Hypothesis traders who use statistical arbitrage to deal with ‘random walks’ or Behavioural Finance experts who build on Amos Tversky and Daniel Kahneman’s Prospect Theory (Kahneman & Tversky). Niederhoffer’s deeper point is that technical analysts’ belief that the “trend is your friend” is no match for the other schools, despite a mini-publishing industry and computer trading systems. There are also ontological and epistemological differences between the schools. Similarly, CJ proponents who adopt a ‘Professional Amateur’ or ‘Pro-Am’ stance (Leadbeater & Miller) may face a similar gulf when making comparisons with professional journalists and the production environments in media organisations. CJ also thrives as new media populism because of institutional vested interests. When media conglomerates cut back on cadetships and internships CJ might fill the market demand as one alternative. New media programs at New York University and others can use CJ to differentiate themselves from “hyperlocal” competitors (Christensen; Slywotzky; Christensen, Curtis & Horn). This transforms CJ from new media populism to new media institution. 5. Parallels: Event-driven & Civic Journalism For new media programs, CJ builds on two earlier traditions: the Event-driven journalism of crises like the 1991 Gulf War (Wark) and the Civic Journalism school that emerged in the 1960s social upheavals. Civic Journalism’s awareness of minorities and social issues provides the character ethic and political philosophy for many Citizen Journalists. Jay Rosen and others suggest that CJ is the next-generation heir to Civic Journalism, tracing a thread from the 1968 Chicago Democratic Convention to IndyMedia’s coverage of the 1999 “Battle in Seattle” (Rosen). Rosen’s observation could yield an interesting historiography or genealogy. Events such as the Southeast Asian tsunami on 26 December 2004 or Al Qaeda’s London bombings on 7 July 2005 are cited as examples of CJ as event-driven journalism and “pro-am collaboration” (Kolodzy 229-230). Having covered these events and Al Qaeda’s attacks on 11th September 2001, I have a slightly different view: this was more a variation on “first responder” status and handicam video footage that journalists have sourced for the past three decades when covering major disasters. This different view means that the “salience of categories” used to justify CJ and “pro-am collaboration” these events does not completely hold. Furthermore, when Citizen Journalism proponents tout Flickr and Wikipedia as models of real-time media they are building on a broader phenomenon that includes CNN’s Gulf War coverage and Bloomberg’s dominance of financial news (Loomis). 6. The Mergers & Acquisitions Scenario CJ proponents often express anxieties about the resilience of their outlets in the face of predatory venture capital firms who initiate Mergers & Acquisitions (M&A) activities. Ironically, these venture capital firms have core competencies and expertise in the event-driven infrastructure and real-time media that CJ aspires to. Sequoia Capital and other venture capital firms have evaluative frameworks that likely surpass Carlile & Christensen in sophistication, and they exploit parallels, information asymmetries and market populism. Furthermore, although venture capital firms such as Union Street Ventures have funded Web 2.0 firms, they are absent from the explanations of some theorists, whose examples of Citizen Journalism and Web 2.0 success may be the result of survivorship bias. Thus, the venture capital market remains an untapped data source for researchers who want to evaluate the impact of CJ outlets and institutions. The M&A scenario further problematises CJ in several ways. First, CJ is framed as “oppositional” to traditional media, yet this may be used as a stratagem in a game theory framework with multiple stakeholders. Drexel Burnham Lambert’s financier Michael Milken used market populism to sell ‘high-yield’ or ‘junk’ bonds to investors whilst disrupting the Wall Street establishment in the late 1980s (Curtis) and CJ could fulfil a similar tactical purpose. Second, the M&A goal of some Web 2.0 firms could undermine the participatory goals of a site’s community if post-merger integration fails. Jason Calacanis’s sale of Weblogs, Inc to America Online in 2005 and MSNBC’s acquisition of Newsvine on 5 October 2007 (Newsvine) might be success stories. However, this raises issues of digital “property rights” if you contribute to a community that is then sold in an M&A transaction—an outcome closer to business process outsourcing. Third, media “buzz” can create an unrealistic vision when a CJ site fails to grow beyond its start-up phase. Backfence.com’s demise as a “hyperlocal” initiative (Caverly) is one cautionary event that recalls the 2000 dotcom crash. The M&A scenarios outlined above are market dystopias for CJ purists. The major lesson for CJ proponents is to include other market players in hypotheses about causation and correlation factors. 7. ‘Pro-Ams’ & Professional Journalism’s Crisis CJ emerged during a period when Professional Journalism faced a major crisis of ‘self-image’. The Demos report The Pro-Am Revolution (Leadbeater & Miller) popularised the notion of ‘professional amateurs’ which some CJ theorists adopt to strengthen their categorisation. In turn, this triggers a response from cultural theorists who fear bloggers are new media’s barbarians (Keen). I concede Leadbeater and Miller have identified an important category. However, how some CJ theorists then generalise from ‘Pro-Ams’ illustrates the danger of ‘weak’ theory referred to above. Leadbeater and Miller’s categorisation does not really include a counter-view on the strengths of professionals, as illustrated in humanistic consulting (Block), professional service firms (Maister; Maister, Green & Galford), and software development (McConnell). The signs of professionalism these authors mention include a commitment to learning and communal verification, mastery of a discipline and domain application, awareness of methodology creation, participation in mentoring, and cultivation of ethical awareness. Two key differences are discernment and quality of attention, as illustrated in how the legendary Hollywood film editor Walter Murch used Apple’s Final Cut Pro software to edit the 2003 film Cold Mountain (Koppelman). ‘Pro-Ams’ might not aspire to these criteria but Citizen Journalists shouldn’t throw out these standards, either. Doing so would be making the same mistake of overconfidence that technical analysts make against statistical arbitrageurs. Key processes—fact-checking, sub-editing and editorial decision-making—are invisible to the end-user, even if traceable in a blog or wiki publishing system, because of the judgments involved. One post-mortem insight from Assignment Zero was that these processes were vital to create the climate of authenticity and trust to sustain a Citizen Journalist community (Howe). CJ’s trouble with “objectivity” might also overlook some complexities, including the similarity of many bloggers to “noise traders” in financial markets and to op-ed columnists. Methodologies and reportage practices have evolved to deal with the objections that CJ proponents raise, from New Journalism’s radical subjectivity and creative non-fiction techniques (Wolfe & Johnson) to Precision Journalism that used descriptive statistics (Meyer). Finally, journalism frameworks could be updated with current research on how phenomenological awareness shapes our judgments and perceptions (Thompson). 8. Strategic Execution For me, one of CJ’s major weaknesses as a new media theory is its lack of “rich description” (Geertz) about the strategic execution of projects. As Disinfo.com site editor I encountered situations ranging from ‘denial of service’ attacks and spam to site migration, publishing systems that go offline, and ensuring an editorial consistency. Yet the messiness of these processes is missing from CJ theories and accounts. Theories that included this detail as “second-order interactions” (Carlile & Christensen 13) would offer a richer view of CJ. Many CJ and Web 2.0 projects fall into the categories of mini-projects, demonstration prototypes and start-ups, even when using a programming language such as Ajax or Ruby on Rails. Whilst the “bootstrap” process is a benefit, more longitudinal analysis and testing needs to occur, to ensure these projects are scalable and sustainable. For example, South Korea’s OhmyNews is cited as an exemplar that started with “727 citizen reporters and 4 editors” and now has “38,000 citizen reporters” and “a dozen editors” (Kolodzy 231). How does OhmyNews’s mix of hard and soft news change over time? Or, how does OhmyNews deal with a complex issue that might require major resources, such as security negotiations between North and South Korea? Such examples could do with further research. We need to go beyond “the vision thing” and look at the messiness of execution for deeper observations and counterintuitive correlations, to build new descriptive theories. 9. Future Research This essay argues that CJ needs re-evaluation. Its immediate legacy might be to splinter ‘journalism’ into micro-trends: Washington University’s Steve Boriss proclaims “citizen journalism is dead. Expert journalism is the future.” (Boriss; Mensching). The half-lives of such micro-trends demand new categorisations, which in turn prematurely feeds the theory-building cycle. Instead, future researchers could reinvigorate 21st century journalism if they ask deeper questions and return to the observation stage of building descriptive theories. In closing, below are some possible questions that future researchers might explore: Where are the “rich descriptions” of journalistic experience—“citizen”, “convergent”, “digital”, “Pro-Am” or otherwise in new media? How could practice-based approaches inform this research instead of relying on espoused theories-in-use? What new methodologies could be developed for CJ implementation? What role can the “heroic” individual reporter or editor have in “the swarm”? Do the claims about OhmyNews and other sites stand up to longitudinal observation? Are the theories used to justify Citizen Journalism’s normative stance (Rheingold; Surowiecki; Pesce) truly robust generalisations for strategic execution or do they reflect the biases of their creators? How could developers tap the conceptual dimensions of information technology innovation (Shasha) to create the next Facebook, MySpace or Wikipedia? References Argyris, Chris, and Donald Schon.
