An investigation of variables influencing the experience of unemployment for blue collar and white collar workers
Creators: name: Feesey, Terrence James
Publisher: name: University of British Columbia
Year: 2010

description: This study was designed to probe the experience of white collar unemployment. Some research results suggest that white collar people have an easier time with unemployment than do blue collar people while other findings suggest the contrary. A questionnaire format instrument was designed to record self-reported changes of an affective and behavioural nature in a sample of 66 white collar and 24 blue collar unemployed adults. It was hypothesized that on the whole, the blue collar sample would report a more difficult response to unemployment than the white collar sample. It was further hypothesized that after an unspecified period of time the unemployed white collar sample would become passive and depressed. Twelve variables focusing on learned helplessness, self-esteem, depression, locus of control, social interaction, time structure, personal meaning and perceived measures of health and finances were recorded and intercorrelated in this relationship study. Correlation matrices were constructed for the general sample, the white collar and the blue collar sub-samples. Reliability and validity coefficients of the instrument were calculated on each variable and were found to be acceptable for the purpose of this study. The relationships among the variables supported the notion that generally, the people in the blue collar unemployed sample experienced more difficulty with unemployment than did those people in the white collar sample. The white collar sample subjects did not, however, show a significant disposition toward passivity and depression as a function of time. Instead, the data suggested the presence of a second white collar subgroup who appeared to be experiencing great personal difficulties regardless of the duration of their unemployment. It was suggested that the appearance of a bi-modal white collar sample was the result of the sampling technique, and further that these results may reflect the state of the real world. This position is offered as a possible justification for the contradictory white collar unemployment findings in the past.

description: This paper addresses the trajectory tracking problem of an autonomous tractor-trailer system by using a fast distributed nonlinear model predictive control algorithm in combination with nonlinear moving horizon estimation for the state and parameter estimation in which constraints on the inputs and the states can be incorporated. The proposed control algorithm is capable of driving the tractor-trailer system to any desired trajectory ensuring high control accuracy and robustness against environmental disturbances.

The Deviated Route: Navigating the Logistical Power Landscape of the Mekong Border Trade
Creators: name: Saiyarod, Panitda
Publisher: name: Advances in Southeast Asian Studies
Year: 2023

description: In the past two decades, the Mekong region has seen an increase in infrastructure projects aimed at improving transportation and connectivity between China and neighboring countries. These projects feature border control points, customs checkpoints, and security forces, leading to state control over cross-border trade mobility. Logistical power has gradually penetrated the social life in border trading, selectively facilitating certain groups while excluding others. Despite the overarching influence of state control, local traders still assert their agency in shaping cross-border trade practices. However, the transport and border control infrastructures hindered small-scale trading during the global pandemic and filtered out less economically important goods from cross-border mobility. This paper highlights the dynamic relationship between state control and various actors in cross-border trade in the Mekong region. It calls for an inclusive strategy in developing border infrastructure, aiming to ensure equitable benefit distribution and actively integrate the voices and experiences of those most impacted by these changes into the planning and execution of regional projects.

description: With the underlying aim of increasing efficiency of computational modelling pertinent for managing & protecting the Great Barrier Reef, we perform a preliminary investigation on the use of deep neural networks for opportunistic model emulation of APSIM models by repurposing an existing large dataset containing outputs of APSIM model runs. The dataset has not been specifically tailored for the model emulation task. We employ two neural network architectures for the emulation task: densely connected feed-forward neural network (FFNN), and gated recurrent unit feeding into FFNN (GRU-FFNN), a type of a recurrent neural network. Various configurations of the architectures are trialled. A minimum correlation statistic is used to identify clusters of APSIM scenarios that can be aggregated to form training sets for model emulation. We focus on emulating 4 important outputs of the APSIM model: runoff, soil_loss, DINrunoff, Nleached. The GRU-FFNN architecture with three hidden layers and 128 units per layer provides good emulation of runoff and DINrunoff. However, soil_loss and Nleached were emulated relatively poorly under a wide range of the considered architectures; the emulators failed to capture variability at higher values of these two outputs. While the opportunistic data available from past modelling activities provides a large and useful dataset for exploring APSIM emulation, it may not be sufficiently rich enough for successful deep learning of more complex model dynamics. Design of Computer Experiments may be required to generate more informative data to emulate all output variables of interest. We also suggest the use of synthetic meteorology settings to allow the model to be fed a wide range of inputs. These need not all be representative of normal conditions, but can provide a denser, more informative dataset from which complex relationships between input and outputs can be learned.

description: Interferometry can completely redirect light, providing the potential for strong and controllable optical forces. However, small particles do not naturally act like interferometric beamsplitters, and the optical scattering from them is not generally thought to allow efficient interference. Instead, optical trapping is typically achieved via deflection of the incident field. Here we show that a suitably structured incident field can achieve beamsplitter-like interactions with scattering particles. The resulting trap offers order-of-magnitude higher stiffness than the usual Gaussian trap in one axis, even when constrained to phase-only structuring. We demonstrate trapping of 3.5 to 10.0~$μ$m silica spheres, achieving stiffness up to 27.5$\pm$4.1 times higher than is possible using Gaussian traps, and two orders of magnitude higher measurement signal-to-noise ratio. These results are highly relevant to many applications, including cellular manipulation, fluid dynamics, micro-robotics, and tests of fundamental physics.
Infrastructure Power, Circulation and Suspension
Creators: name: Oakes, Tim
Publisher: name: Advances in Southeast Asian Studies
Year: 2023

description: This brief commentary begins with the premise that infrastructures are not neutral technical platforms upon which more interesting social activities (such as various kinds of mobility) occur. Instead, infrastructures are more productively understood as bundles of socio-technical relations, and these relations shape in often unintended ways the social, political, economic, and environmental effects of infrastructural configurations. Infrastructural power, then, is understood as a relational form of power emergent within infrastructural configurations themselves, rather than simply as pre-existing state power channeled through infrastructures. This approach suggests that mobility is more than just a social construction or an outcome of state policy, but is generated through infrastructural power. Drawing on research on new town development in China, I argue that new patterns of mobility – what I call ‘suspended circulation’ – emerge as effects of the spatial configurations created by infrastructures that have preceded urbanization in these places. These new patterns of mobility involve the continuous circulation of precarious labor throughout ever-expanding spaces of urban development. While this aligns in many ways with the modernist and developmentalist projects of the state, it also indexes a form of material power over which the state has limited control

description: A local classification of spacelike surfaces in Minkowski 4-space, which are invariant under spacelike rotations, and with mean curvature vector either vanishing or lightlike, is obtained. Furthermore, the existence of such surfaces with prescribed Gaussian curvature is shown. A procedure is presented to glue several of these surfaces with intermediate parts where the mean curvature vector field vanishes. In particular, a local description of marginally trapped surfaces invariant under spacelike rotations is exhibited.

description: Stochastic variance reduced gradient (SVRG) is a popular variance reduction technique for accelerating stochastic gradient descent (SGD). We provide a first analysis of the method for solving a class of linear inverse problems in the lens of the classical regularization theory. We prove that for a suitable constant step size schedule, the method can achieve an optimal convergence rate in terms of the noise level (under suitable regularity condition) and the variance of the SVRG iterate error is smaller than that by SGD. These theoretical findings are corroborated by a set of numerical experiments.

description: We report structural, magnetization, electrical resistivity and nuclear- and electron spin resonance data of the complex transition metal oxide In_2VO_5 in which structurally well-defined V-O chains are realized. An itinerant character of the vanadium d-electrons and ferromagnetic correlations, revealed at high temperatures, are contrasted with the insulating behavior and predominantly antiferromagnetic exchange between the localized V^{4+} S = 1/2-magnetic moments which develop below a certain characteristic temperature T* ~ 120 K. Eventually the compound exhibits short-range magnetic order at $T_SRO ~ 20 K. We attribute this crossover occurring around T* to the unusual anisotropic thermal contraction of the lattice which changes significantly the overlap integrals and the character of magnetic intra- and interchain interactions.

Chinese Investor Networks and the Politics of Infrastructure Projects in the Eastern Economic Corridor in Thailand
Creators: name: Ayuttacorn, Arratee
Publisher: name: Advances in Southeast Asian Studies
Year: 2023

description: This research examines Chinese investment and the impact of infrastructure projects on the Eastern Economic Corridor project (EEC), a special economic zone linking Thailand with Cambodia, Laos, Myanmar, Vietnam, and China, which aligns with the Belt and Road Initiative (BRI). Drawing on Actor Network Theory (ANT), this study analyzes emerging Chinese investor networks and the resulting negotiations between various actors such as the Thai state, Chinese and Thai investors, and local farmers. Many Chinese investors have moved their production bases to avoid the tax barriers raised by the United States or Europe, as well as to expand their markets in Southeast Asia. The Thai state offers tax benefits to foreign investors, allowing them to import raw materials and machinery from China, making their production costs lower than those of Thai investors. The findings reveal that the neoliberal state facilitates foreign investors through deregulation: enacting city planning laws that permit the establishment of industrial estates in agricultural zones, thus dispossessing farmers of their land. These factories can release toxic waste, thus impacting the local environment and livelihoods of nearby farmers. Thai business-people are often unable to compete with Chinese investors to match their bids. In order to maintain their positions in these economic networks, they build affective relations with Chinese investors. In addition, these affective relations attract resistance and indignation from locals dispossessed of land and resources.

Nonclassical cosmological dynamics in the low-energy limit of loop quantum scalar-tensor theory
Creators: name: Han, Yu
Publisher: name: arXiv
Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In previous work, we showed that in loop quantum cosmology of scalar-tensor theory (STT) with the holonomy correction the background equations of motion in the Jordan frame have two branches, i.e., the $b_{+}$ branch and the $b_{-}$ branch. In the low-energy limit, the $b_{+}$ branch of the equations of motion reproduce the equations of motion of classical STT while the $b_{-}$ branch of equations of motion do not reproduce the classical equations. In this paper, we investigate cosmological dynamics in an expanding universe whose background is described by the the $b_{-}$ branch of equations of motion of STT, and we especially focus on the dynamics of the perturbations in the low-energy limit because it is most relevant to the current observational range. First, we find a low-energy effective Hamiltonian which can yield the low-energy limit of the $b_{-}$ branch of equations, this Hamiltonian consists of constraints whose constraint algebra is different from the classical case but also closed up to arbitrary order of perturbations. Remarkably, we find that this Hamiltonian can be transformed into the Hamiltonian of the Einstein frame by field redefinitions. Moreover, we also develop the linear cosmological perturbation theory and apply it to study the slow-roll inflation. Finally, we study a specific model of STT. In this model, a contracting universe described by classical STT in the remote past can pass through the bounce and evolve into an expanding universe whose background dynamics is described by the $b_{-}$ branch of equations of motion. It is shown that the slow-roll inflation can take place in this case, and the spectral indices of the slow-roll inflation agree well with the observations. The results in this paper indicate that there exists an alternative consistent theory which is different from the classical theory in the low-energy limit of loop quantum STT.

Entangled Enclaves: Dams, Volatile Rivers, and Chinese Infrastructural Engagement in Cambodia
Creators: name: Käkönen, Mira
Publisher: name: Advances in Southeast Asian Studies
Year: 2023

description: This article seeks to advance understanding of the changing interconnections between rivers, infrastructure, and power relations as well as how these are increasingly shaped by a globalizing China and climate change. To do so, it analyzes damming practices in Cambodia and their evolution under a post-neoliberal, concessionary governing mode that materializes in enclaves of corporate authority under Chinese state-owned enterprises. Drawing from the literature on the political life of Chinese overseas infrastructure projects, this article develops the idea of ambiguously entangled enclaves. The focus is on the four most recent large-scale dams in Cambodia and the kinds of dis/connections, altered hydrosocial relations, and power dynamics they generate. The article highlights patterns of dis/entanglement that illuminate the role of Chinese infrastructural engagement in shaping new political-ecological relations and socio-spatial formations in Cambodia and beyond. It also adds insights into the multidimensional geography of enclavism in the Mekong Region.

The Politicization of Mobility Infrastructures in Vietnam - The Hanoi Metro Project at the Nexus of Urban Development, Fragmented Mobilities, and National Security
Creators: name: Nicolaisen, Franziska S.
Publisher: name: Advances in Southeast Asian Studies
Year: 2023

description: This paper critically discusses the Hanoi Metro and its role in contemporary urban development processes in Hanoi. It aims to disentangle the complex interplay between the state’s urban development goals, local mobility patterns, and Sino-Vietnamese relations that influence discourses surrounding the Hanoi Metro. This paper argues that the Hanoi Metro project demonstrates that mobility infrastructures serve as an arena for state-society negotiations in Vietnamese cities. Rooted in the state’s vision of modernity, the metro is promoted as offering an alternative to individual motorized transport, improving urban traffic and mobility for all residents. However, controversies regarding corruption, safety, and Chinese involvement in the financing and construction of Line 2A have negatively affected public perception of the project during its construction period. The potential impact of the Hanoi Metro on urban mobility in a setting dominated by motorbikes is discussed using the mobilities paradigm, with a focus on local mobility practices and experiences. The findings are linked to broader discussions on Chinese investment and historically-rooted notions of modernity and civilization in the context of the long-term development goals of municipal authorities and rising anti-Chinese sentiments in Vietnamese society.

Evaluation of the effectiveness of the Creative Parenting Program

Publisher: name: University of British Columbia

description: The purpose of this study was to investigate the effectiveness of the Creative Parenting Program on the parent participants in the program. The investigation was conducted using a scientific research approach with standardized instruments designed to measure change or lack of change in the parents' perceptions of their approaches to child-rearing. A critical review of the related literature showed no evaluation of parent education programs such as the Creative Parenting Program, based theoretically in the psychology of human development using a lecture style format. The parent education programs evaluated were primarily skill training programs. As each study used different instruments to measure different effects and also different populations, it was not possible to accurately assess the overall effectiveness of the programs. The literature suggested that more research is required to establish significant statistical evidence that the programs change the parental attitudes toward the parent-child relationship. It was hypothesized (null form) that there would be no statistically significant difference between the experimental groups and the control groups of the parents' perceptions in: (1) acceptance of their children; (2) family cohesion and family adaptability; (3) use of authority with their children and (4) family disharmony. The post test score means among groups showed statistically significant changes toward a higher level of acceptance of their children and a decrease in parental use of their authority. On the family interactional dimensions of family cohesion and family adaptability no significant changes were shown. With the dimension of family disharmony no significant changes were shown on the post test score means among groups. The results of the study suggest that the Creative Parenting program is effective in promoting change in the parental attitudes of acceptance of children and reduced use of authority, two factors thought to be basic to effective parenting. It is felt that the principles and concepts presented in the Creative Parenting Program offer a significant contribution to the field of parent education.
Infrastructural Fragility, Infra-Politics and Jianghu

Publisher: name: Advances in Southeast Asian Studies

description: This commentary responds to Tim Oakes' analysis of infrastructural power by examining the inherent fragility of mobility infrastructures and their political ramifications. It emphasizes the human element in creating and maintaining these infrastructures, highlighting the intricate interplay of political will, bureaucratic planning, technological know-how, and specialized skills needed for their implementation. The paper contends that the COVID-19 pandemic has starkly demonstrated the vulnerability of mobility infrastructures to rapid collapse. It further explores the concept of infra-politics, referring to subtle acts of resistance within these networks, which significantly disrupt their efficient operation. The Chinese concept of jianghu, representing a metaphorical space of alterity, is introduced to propose that infra-politics might evolve into alternative relational forms, challenging and potentially subverting the dominance of centralized networks.

description: Since the launch of the BRI, particular modes of movement are integral to its vision of what it means to be a modern world citizen. Nowhere is this more apparent than in Southeast Asia, where China-backed infrastructure projects expand, and at great speed. Such infrastructure projects are carriers of particular versions of modernity, promising rapid mobility to populations better connected than ever before. Yet, until now, little attention has been paid to how mobility and promises of mobility intersect with local understandings of development. In the introduction to this special issue, we argue that it is essential to think about the role infrastructure plays in forms of development that place connectivity at the center. We suggest that considering development, mobility and modernity together is enlightening because it interrogates the connections between these interlocking themes. Through an introduction to five ethnographically grounded papers and two commentaries, all of which engage with infrastructures in different contexts throughout Southeast Asia, we demonstrate that there are significant gaps between official policy and lived experience. This makes the need to interrogate what infrastructure, mobilities, and global China really mean all the more pressing

description: We investigate the effects of weakly-interacting massive particle (WIMP) dark matter annihilation on the formation of Population III.1 stars, which are theorized to form from the collapse of gas cores at the centers of dark matter minihalos. We consider the relative importance of cooling due to baryonic radiative processes and heating due to WIMP annihilation. We analyze the dark matter and gas profiles of several halos formed in cosmological-scale numerical simulations. The heating rate depends sensitively on the dark matter density profile, which we approximate with a power law rho_chi ~ r^{-alpha_chi}, in the numerically unresolved inner regions of the halo. If we assume a self-similar structure so that alpha_chi ~= 1.5 as measured on the resolved scales ~1pc, then for a fiducial WIMP mass of 100GeV, the heating rate is typically much smaller (<10^{-3}) than the cooling rate for densities up to n_H=10^{17}cm^{-3}. In one case, where alpha_chi=1.65, the heating rate becomes similar to the cooling rate by a density of n_H=10^{15}cm^{-3}. The dark matter density profile is expected to steepen in the central baryon-dominated region

Effetto dell’ormone T3 sulla risposta metabolica e sullo stress ossidativo nel muscolo scheletrico di ratti sedentari ed allenati

description: Nel presente lavoro è stata valutata la capacità dell'allenamento fisico graduato di modificare gli effetti indotti dall' ormone T3 sul metabolismo e sul danno ossidativo nel muscolo di ratto. Sono state condotte indagini atte a valutare le capacità respiratorie tessutali e mitocondriali, il danno ossidativo in omogenati e mitocondri,i livelli di antiossidanti e la suscettibilità ai cambiamenti ossidativi degli omogenati nonchè la capacità mitocondriale di rilasciare e rimuovere H2O2.Il tessuto muscolare dei ratti trattati con T3 esibisce un incremento nelle capacità respiratorie che risulta associato con l'aumento nelle capacità respiratorie mitocondriali, nei ratti sedentari, e con l'aumento nel contenuto tessutale di proteine mitocondriali, negli allenati. Il trattamento ormonale induce nel muscolo una condizione di stress ossidativo, documentato dai livelli dei markers di danno ossidativo, ed una riduzione nel contenuto di GSH. I nostri risultati mostrano che entrambi gli effetti sono ridotti dal training e che l'allenamento diminuisce anche la suscettibilità del tessuto muscolare ai cambiamenti ossidativi.Le variazioni nei livelli dei singoli antiossidanti sembrano essere poco correlati all' estensione del danno ossidativo, tuttavia l' analisi dei parametri riguardanti la suscettibilità agli ossidanti indica che l' allenamento è associato ad una maggiore efficacia del sistema di difesa antiossidante.Inoltre il trainig attenua l'incremento nella produzione di H2O2 indotto dalla T3 e quindi il danno ossidativo dei mitocondri, riducendo il loro contenuto di carriers elettronici autossidabili. I nostri risultati, in conclusione, suggeriscono che l' allenamento moderato è in grado di ridurre il danno ossidativo, legato alla condizione di ipertiroidismo, aumentando la protezione antiossidante e riducendo il flusso di ROS dai mitocondri al compartimento citoplasmatico.

Driving behaviour for ADAS: theoretical and experimental analyses
Creators: name: Pariota, Luigi
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: This thesis deals with the analysis and understanding of drivers’ behaviours under car-following. The aim is to enhance the modelling tools toward the development of new ADAS (Advanced Driving Assistance System) logics, characterized by a more human-like behaviour. After having introduced the argument of the thesis (and motivated the work) and having recalled the state of the art most relevant in the field of car-following (as well as in the instruments for observing car-following in the real world), the thesis evolves toward three main sections: actual observation of real-world data and collection of the datasets to be employed for theoretical analysis; theoretical enhancements and propositions; applications to ACC (Adaptive Cruise Control), as a relevant field for ADAS.
The data employed in this work have been collected in three different field surveys, two of them carried out in Italy and the other in the United Kingdom. In all cases data have been collected by instrumented vehicles, equipped in such a way to observe and record car-following trajectories. Data have been framed into different theoretical paradigms in order to both validate each theory and to establish the links between these theories. Links have been established both in a formal way (through theoretical investigation) and in a data-driven way. The considered theoretical paradigm for modelling car-following follows different approaches: one is based on the psycho-physical approach and two others are based on an engineering-inspired approach. In particular, the considered psycho-physical approach has been the Action Point theory (Wiedemann, 1974); a revised version of the paradigm, more compliant with the original version of Barbosa (1961) and Todosoiev (1963) has been proposed and justified with reference to the collected data.
The first engineering paradigm has been based on a state-space approach. The proposed approach has been shown to be consistent with the Action Point theory. The parameters of the model have been estimated by means of the collected data and the obtained results have been discussed; they are consistent with observations and justify the adopted model. The other engineering model is based on a linear approximation (at any time t, in a discrete-time approach) of the response of the follower to the leader’s stimuli. Also the linear model is shown to be a very good approximation of the observed data; moreover, it has been shown to lead to an harmonic oscillation around the desired spacing at steady-state. This oscillation is consistent with both the Action Point theory and (partially) with the proposed state-space approach. The linear model is particularly suitable for real-time ACC-oriented application; thus it is the model employed in section 4 of this work, where a fully-adaptive ACC system is developed, able to actuate a driving-style actually consistent with driver’s expectations and preferences.

description: Quadruple helices, or G-quadruplexes, are DNA secondary structures found in
guanine rich oligonucleotide sequences, having a natural propensity to self-associate in coplanar arrays of four guanines, stabilized by Hoogsteen hydrogen bonding. The scientific interest towards these particular DNA structures is mainly due to the presence of guanine rich domains, potentially able to form G-quadruplexes, in important regions of the human genome, as gene promoters and telomeres, and to the fact that the G-quadruplexes can constitute the scaffold of aptamers. Aptamers are short DNA or RNA fragments capable to bind with high affinity specific proteins, as for example thrombin or HIV-proteins. On these grounds, aptamers-based synthetic oligonucleotides can represent a new class of pharmacologically interesting
molecules, characterized by a high selectivity of action. Furthermore, the Gquadruplexes can have a potential use in nanotechnology. As a matter of fact, the overall quadruplex scaffold can exhibit several morphologies through intramolecular or intermolecular organization of G-rich oligonucleotide strands, which can form higher-order assemblies by multimerization between G-quadruplex units.
In these contests, my research studies have been mainly focused on: i) Investigation of the most prominent biological properties of selected Gquadruplexes and identification of bioactive sequences able to play a
biological role as aptamers; and ii) Elucidation of the sequence-specific thermodynamic stability and physicalchemical mechanisms that underlie the G-quadruplexes multimerization.
Specifically, during my PhD research studies, I focused on anti-HIV aptamers, and Thrombin Binding Aptamer (TBA) with the aim to identify the structural features required for their biological activity and reaching the way to improve them. Furthermore, I identify the CGGXGGT oligonucleotide sequence (where X = A, C, G, or T) able to lead to the formation of higher order G-quadruplex assemblies, that can potentially be used as DNA-based nanostructures.
In order to achieve these objectives, it has been necessary to exploit the synthesis and the structural characterization of quadruplex-forming oligonucleotides, the analysis of the sequence-specific thermodynamic stability, the physical-chemical properties and the structural features of resulting G-quadruplexes. Furthermore, as regard the studies about aptamers, the evaluation of the binding properties to the selected proteins, and bioassays to ascertain the biological properties of the synthesized complexes have been undertaken.

description: Based on the microscopic mechanisms of (1) charge-excitation-induced negative effective U in s^1 or d^9 electronic configurations, and (2) exchange-correlation-induced negative effective U in d^4 or d^6 electronic configurations, we propose a general rule and materials design of negative effective U system in itinerant (ionic and metallic) system for the realization of high-T_c superconductors. We design a T_c-enhancing layer (or clusters) of charge-excitation-induced negative effective $U$ connecting the superconducting layers for the realistic systems.

Applications for keyboarding with students with motor dysfunction
Creators: name: Snider, Laurie Margaret
Publisher: name: University of British Columbia
Year: 2010

description: This study used the word processor as a tool for written output to examine the effects of an experiential 'Write to Read' program on typing performance, decoding strategies and successive processing in learning disordered children with motor dysfunction. A case history approach was taken in view of the small number of subjects available, and in order to adequately describe each individual's unique and complex cognitive motor profile. Subjects involved in the study were three male students in a Junior Learning Assistance Class in a Lower Mainland British Columbia school district elementary school. Each of the students had a history of poor motor performance, poor handwriting and delayed reading ability. The three subjects were involved in an eight week intervention program which taught keyboarding and word processing techniques using the 'Write to Read' program, a systematic method of training the motor skills required. It was hypothesized that, if the learning disabled student with poor motor skills could use the word processor as an adjunct to handwriting, the improved legibility would facilitate consistent decoding by the student of his own work, reinforcing acquisition of early reading skills. Within the case history format, a theoretical frame of reference based on the simultaneous - successive information processing model was chosen and a limited time series design measured the effects of the intervention on successive processing as determined by a block sequencing task (Das, Kirby and Jarman, 1980). The data was collected for each student and graphed for visual inspection, graphic analysis and statistical analysis. One subject showed a stable and significant intervention effect, and no stable trends or significant results for successive processing were found in the other two subjects. Rates of word processing output increased over the course of the study and the number of errors declined. All subjects made progress in measures of decoding and word analysis. Implications for future research and professional practice were described.

description: We explore what benefits network position in online business social networks like LinkedIn might confer to an aspiring entrepreneur. We compare two network attributes, size and embeddedness, and two actor attributes, location and diversity, between virtual and real-world networks. The promise of social networks like LinkedIn is that network friends enable easier access to critical resources such as legal and financial services, customers, and business partners. Our setting consists of one million public member profiles of the German business networking site XING (a German version of LinkedIn) from which we extracted the network structure of 15,000 start-up entrepreneurs from 12 large German universities. We find no positive effect of virtual network size and embeddedness, and small positive effects of location and diversity.
