Modeling the transition to a new economy: lessons from two technological revolutions

OpenAIRE

Andrew Atkeson; Patrick J. Kehoe

2006-01-01

Many view the period after the Second Industrial Revolution as a paradigmatic example of a transition to a new economy following a technological revolution and conjecture that this historical experience is useful for understanding other transitions, including that after the Information Technology Revolution. We build a model of diffusion and growth to study transitions. We quantify the learning process in our model using data on the life cycle of U.S. manufacturing plants. This model accounts...

The explorations of rare-earth, transition metal intermetallics have resulted in the synthesis and characterization, and electronic structure investigation, as well as understanding the structure-bonding property relationships. The work has presented the following results: (1) Understanding the relationship between compositions and properties in LaFe_13-xSi_x system: A detailed structural and theoretical investigation provided the understanding of the role of a third element on stabilizing the structure and controlling the transformation of cubic NaZn{sub 13}-type structures to the tetragonal derivative, as well as the relationship between the structures and properties. (2) Synthesis of new ternary rare-earth iron silicides Re_2-xFe₄Si_14-y and proposed superstructure: This compound offers complex structural challenges such as fractional occupancies and their ordering in superstructure. (3) Electronic structure calculation of FeSi₂: This shows that the metal-semiconductor phase transition depends on the structure. The mechanism of band gap opening is described in terms of bonding and structural distortion. This result shows that the electronic structure calculations are an essential tool for understanding the relationship between structure and chemical bonding in these compounds. (4) Synthesis of new ternary rare-earth Zinc aluminides Tb₃Zn_3.6Al_7.4: Partially ordered structure of Tb₃Zn_3.6Al_7.4 compound provides new insights into the formation, composition and structure of rare-earth transition-metal intermetallics. Electronic structure calculations attribute the observed composition to optimizing metal-metal bonding in the electronegative (Zn, Al) framework, while the specific ordering is strongly influenced by specific orbital interactions. (5) Synthesis of new structure type of Zn₃₉(Cr_xAl_1-x)₈₁

Characterization of frequency-dependent glass transition temperature by Vogel-Fulcher relationship

International Nuclear Information System (INIS)

Bai Yu; Jin Li

2008-01-01

The complex mechanical modulus of polymer and polymer based composite materials showed a frequency-dependent behaviour during glass transition relaxation, which was historically modelled by the Arrhenius equation. However, this might not be true in a broad frequency domain based on the experience from the frequency dependence of the complex dielectric permittivity, which resulted from the same glass transition relaxation as for the complex mechanical modulus. Considering a good correspondence between dielectric and mechanical relaxation during glass transition, the Vogel-Fulcher relationship, previously proposed for the frequency dependence of dielectric permittivity, is introduced for that of the mechanical modulus; and the corresponding static glass transition temperature (T f ) was first determined for polymer and polymer based composite materials.

Wisaksono, A.; Murphy, J.; Sharp, J. H.; Younger, P. L.

2018-01-01

The study adopts a multi-level perspective in technology transition to analyse how the transition process in the development of geothermal energy in Indonesia is able to compete against the incumbent fossil-fuelled energy sources. Three levels of multi-level perspective are socio-technical landscape (ST-landscape), socio-technical regime (ST-regime) and niche innovations in Indonesia geothermal development. The identification, mapping and analysis of the dynamic relationship between each level are the important pillars of the multi-level perspective framework. The analysis considers the set of rules, actors and controversies that may arise in the technological transition process. The identified geothermal resource risks are the basis of the emerging geothermal technological innovations in Indonesian geothermal. The analysis of this study reveals the transition pathway, which yields a forecast for the Indonesian geothermal technology transition in the form of scenarios and probable impacts.

SIW based multilayer transition and power divider in LTCC technology

KAUST Repository

Abuzaid, Hattan

2013-06-01

A multilayer transition and balanced power divider are presented for millimeter-wave system-on-package (SoP). These two components operate at Ka-band and exploit the substrate integrate waveguide (SIW) technology with its shielding characteristics and the Low-temperature co-fired ceramics (LTCC) technology for its high density integration. A coupling slot has been used to perform vertical integration, which can be easily optimized through its length. The measured input return loss within the bandwidth of interest (32 GHz-38 GHz) is less than -15 dB and -18 dB for the multilayer transition and the power divider, respectively. The lateral dimensions of a multilayer system, such as a feed network of an array, can be greatly reduced by employing these 3D slot-coupled components. © 2013 IEEE.

Chen, Shih-Chih; Jong, Din; Lai, Min-Tsai

2014-09-01

Numerous types of self-service technologies have prevailed due to innovations in network and information technology. To hospitals, patient intentions to continue to use the e-appointment system are crucial. Previous investigations discussed only the relationships between the technology readiness of users and their continuance intentions, and ignored the most important mediator, relationship quality. This study explored the relationships among technology readiness, relationship quality, and continuance intention. The research results demonstrated that both optimism and innovativeness significantly and positively influenced continuance intention through the mediating effect of relationship quality. However, discomfort and insecurity hid not significantly influence relationship quality or continuance intention. Finally, theoretical contributions, managerial implications and future research directions were discussed.

Zaman, Khalid; Khan, Muhammad Mushtaq; Ahmad, Mehboob; Rustam, Rabiah

2012-01-01

The purpose of this study was two fold: (i) to investigate the casual relationship between energy consumption and agricultural technology factors, and (ii) electricity consumption and technological factors in the agricultural sector of Pakistan. The study further evaluates four alternative but equally plausible hypotheses, each with different policy implications. These are: (i) Agricultural technology factors cause energy demand (the conventional view), (ii) energy demand causes technological factors, (iii) There is a bi-directional causality between the two variables and (iv) Both variables are causality independent. By applying techniques of Cointegration and Granger causality tests on energy demand (i.e., total primary energy consumption and electricity consumption) and agricultural technology factors (such as, tractors, fertilizers, cereals production, agriculture irrigated land, high technology exports, livestock; agriculture value added; industry value added and subsides) over a period of 1975–2010. The results infer that tractor and energy demand has bi-directional relationship; while irrigated agricultural land; share of agriculture and industry value added and subsides have supported the conventional view i.e., agricultural technology cause energy consumption in Pakistan. On the other hand, neither fertilizer consumption and high technology exports nor energy demand affect each others. Government should form a policy of incentive-based supports which might be a good policy for increasing the use of energy level in agriculture. - Highlights: ► Find the direction between green technology factors and energy demand in Pakistan. ► The results indicate that there is a strong relationship between them. ► Agriculture machinery and energy demand has bi-directional relationship. ► Green technology causes energy consumption i.e., unidirectional relationship. ► Agriculture expansion is positive related to total primary energy consumption.

2015-12-01

Full Text Available The purpose of this study was to investigate the relationship between technology leadership behaviors of school principals and teachers’ level of technology integration, and to determine technology leadership profiles based on teacher views and examine their association with technology integration. The researchers administered two questionnaires to 352 teachers working at sixteen primary schools in a large city in southeastern Turkey. The results revealed a positive, but weak relationship between technology leadership and technology integration. Furthermore, it was concluded that there were positive but weak relationships among technology integration and human centeredness, communication and collaboration, vision and support sub-dimensions of technology leadership. Two technology leadership profiles (high-TLP=65.6% and low-TLP=34.4% were constructed as a result of cluster analysis. A statistically significant difference was detected between teachers’ technology integration perceptions which were categorized into two profiles. The paper concludes by suggestions for implications to strengthen the link between technology leadership and technology integration.

The paper analyses possible implications for Croatia of a global transition towards new energy technology systems, as depicted by the recent report on scenarios and strategies to 2050 of the International Energy Agency [ETP2008]. The analysis is based upon the present Croatian energy balance. It takes into account some draft results of the USAID-supported Regional Energy Demand Planning (REDP) study under the South East Europe Regional Energy Market Support (SEE REMS) Project. The paper then presents ongoing EC-funded energy research projects, such as RES2020 (Monitoring and Evaluation of the Renewable Energy Sources directives implementation in EU27 and policy recommendations for 2020), REACCESS (Risk of Energy Availability: Common Corridors for Europe Supply Security) and REALISEGRID (REseArch, methodoLogIes and technologieS for the effective development of pan-European key GRID infrastructures to support the achievement of a reliable, competitive and sustainable electricity supply). The participation of Croatian research organizations to EC-funded research projects could make the transition towards new energy system an opportunity for economic development.(author)

Do self-service technologies affect interfirm relationships? A B2B perspective

Directory of Open Access Journals (Sweden)

Raechel Johns

2014-11-01

Full Text Available While considerable literature examines business-to business (B2B relationships, the impact of technology on these relationships has lacked attention. IT has impacted the way businesses operate in a B2B context as well as influencing services by altering the way services are delivered. To understand the way in which Internet technology has impacted these B2B services, it is essential to examine its impact not only on business processes but on business relationships too. One technology, enabled by modern Internet technologies, which is changing the nature of business relationships is the increased use of self-service technologies (SSTs or technology-enabled services, however, there is a shortage of research in the area in a B2B context. The discussion in this paper provides an overview of the impact of IT on business relationships, using Relationship Marketing theory to provide a theoretical framework. A qualitative study in the Australian banking industry provides findings relating to the theory. The findings of this study provide evidence that while traditional Relationship Marketing theory is still applicable for some business customers, new theory is required for business customers who do not seek relationships. With both practical and theoretical implications, the research detailed in this paper makes a useful contribution to the literature and indicates the necessity for further research to be developed which explores business customers who prefer to remain transaction-oriented, rather than develop interpersonal relationships.

Guo, Pibin; Wang, Ting; Li, Dan; Zhou, Xijun

2016-01-01

The aim of this research paper is to investigate factors and mechanisms that may facilitate the transition from coal resource-based economy to sustainability. Based on the energy technology innovation theory, factors that may influence the transition of coal resource-based economy were categorized into four types, including: innovation policy, innovation input, innovation ability, and innovation organization. Hypotheses were proposed regarding the mechanisms of these factors. Data were collected from surveys administered to 314 Chinese energy firms, and a structural equation model (SEM) was employed to test the hypotheses. Ten of fifteen hypotheses were retained based on the reliability tests, validity tests, and SEM. The results show that the four proposed factors are crucial in transforming the coal resource-based economy, and the effects become statistically significant through three intermediate variables, namely, transition of energy consumption structure, correction of resource wealth investment, and improvement of transition environment. - Highlights: •Approximately, 66% of energy relies on coal in China. •Serious environment problems have occurred in many coal-based regions. •Energy technology innovation can promote the transition of coal-based economy. •China should accelerate the development of clean energy.

Nocturnal Hot Flashes: Relationship to Objective Awakenings and Sleep Stage Transitions

Science.gov (United States)

Bianchi, Matt T.; Kim, Semmie; Galvan, Thania; White, David P.; Joffe, Hadine

2016-01-01

Study Objectives: While women report sleep interruption secondary to nighttime hot flashes, the sleep disrupting impact of nocturnal hot flashes (HF) is not well characterized. We utilized a model of induced HF to investigate the relationship of nighttime HF to sleep architecture and sleep-stage transitions. Methods: Twenty-eight healthy, premenopausal volunteers received the depot gonadotropin-releasing hormone agonist (GnRHa) leuprolide to rapidly induce menopause, manifesting with HF. Sleep disruption was measured on 2 polysomnograms conducted before and after 4–5 weeks on leuprolide, when HF had developed. Results: 165 HF episodes were recorded objectively during 48 sleep studies (mean 3.4 HF/night). After standardizing to sleep-stage time distribution, the majority of HF were recorded during wake (51.0%) and stage N1 (18.8%). Sixty-six percent of HF occurred within 5 minutes of an awakening, with 80% occurring just before or during the awakening. Objective HF were not associated with sleep disruption as measured by increased transitions to wake or N1, but self-reported nocturnal HF correlated with an increase from pre- to post-leuprolide in the rate of transitions to wake (p = 0.01), and to N1 (p = 0.008). Conclusions: By isolating the effect of HF on sleep in women without the confound of age-related sleep changes associated with natural menopause, this experimental model shows that HF arise most commonly during N1 and wake, typically preceding or occurring simultaneously with wake episodes. Perception of HF, but not objective HF, is linked to increased sleep-stage transitions, suggesting that sleep disruption increases awareness of and memory for nighttime HF events.

Full Text Available The work focuses on the analysis of the bilateral relationship between technological changes and inequality. First, it focus on the impact of technological innovations on inequality and the theory of Skills Biased Technological Changes (SBTC. Given technology can produce inequality; what is the impact of these inequalities on the distribution and the production technologies? Conversely, it´s interested in, the transmission channels through which inequality affect technological changes. And that being said, let's enrich the interactions between inequality and technological changes. The empirical validation is based on the technique of Panel data for a sample of developing countries. The paper concludes that a positive relationship of technological changes on inequality seems to be confirmed. Increased innovation increases inequality. And a negative effect of inequality on technological changes also seems to be confirmed. Rising inequality hampers technological innovations.

Tele-analysis: the use of media technology in psychotherapy and its impact on the therapeutic relationship.

Science.gov (United States)

Roesler, Christian

2017-06-01

A growing number of approaches in psychotherapy make use of internet- and other media-based interactions. This paper discusses the impact on the therapist-client relationship of using media technology and gives an overview of the current state of the debate. It is suggested that the technical conditions of internet-based interactions produce new forms of social relationships that differ significantly from face-to-face-interactions and that unconscious, nonverbal cues get lost. Research on the therapeutic interaction making use of 'discourse linguistic' methods is presented. The loss of nonverbal cues has implications for psychotherapy in general and especially for the treatment of patients who have difficulties relying on a secure therapeutic relationship. Emotional security in interactional relationships is transmitted to a much greater extent by nonverbal cues than by verbal content; psychoanalytic methods are specialized to refer to this level of interaction. Two alternative scenarios are discussed based on the psychoanalytic theories of Winnicott and Lacan: the risk of an illusionary, idealized image of the other and the possibility that cyberspace can be used for psychological development as a transitional space. © 2017, The Society of Analytical Psychology.

A cautionary approach in transitioning to 'green' energy technologies and practices is required.

Science.gov (United States)

Matatiele, Puleng; Gulumian, Mary

2016-06-01

Renewable energy technologies (wind turbines, solar cells, biofuels, etc.) are often referred to as 'clean' or 'green' energy sources, while jobs linked to the field of environmental protection and energy efficiency are referred to as 'green' jobs. The energy efficiency of clean technologies, which is likely to reduce and/or eliminate reliance on fossil fuels, is acknowledged. However, the potential contribution of green technologies and associated practices to ill health and environmental pollution resulting from consumption of energy and raw materials, generation of waste, and the negative impacts related to some life cycle phases of these technologies are discussed. Similarly, a point is made that the green jobs theme is mistakenly oversold because the employment opportunities generated by transitioning to green technologies are not necessarily safe and healthy jobs. Emphasis is put on identifying the hazards associated with these green designs, assessing the risks to the environment and worker health and safety, and either eliminating the hazards or minimizing the risks as essential elements to the design, construction, operation, and maintenance of green technologies. The perception that it is not always economically possible to consider all risk factors associated with renewable energy technologies at the beginning without hampering their implementation, especially in the poor developing countries, is dismissed. Instead, poor countries are encouraged to start implementing environmentally sound practices while transitioning to green technologies in line with their technological development and overall economic growth.

Non-Linear Relationship between Economic Growth and CO₂ Emissions in China: An Empirical Study Based on Panel Smooth Transition Regression Models.

Science.gov (United States)

Wang, Zheng-Xin; Hao, Peng; Yao, Pei-Yi

2017-12-13

The non-linear relationship between provincial economic growth and carbon emissions is investigated by using panel smooth transition regression (PSTR) models. The research indicates that, on the condition of separately taking Gross Domestic Product per capita (GDPpc), energy structure (Es), and urbanisation level (Ul) as transition variables, three models all reject the null hypothesis of a linear relationship, i.e., a non-linear relationship exists. The results show that the three models all contain only one transition function but different numbers of location parameters. The model taking GDPpc as the transition variable has two location parameters, while the other two models separately considering Es and Ul as the transition variables both contain one location parameter. The three models applied in the study all favourably describe the non-linear relationship between economic growth and CO₂ emissions in China. It also can be seen that the conversion rate of the influence of Ul on per capita CO₂ emissions is significantly higher than those of GDPpc and Es on per capita CO₂ emissions.

The market scale of China’s wind turbine manufacturing industry has grown immensely. Despite China still having a limited capacity in terms of technology innovation, the institutional support has promoted the technology capability development of the wind turbine manufacturing industry. This paper explores the driving forces underlying this development by reviewing the transition of the innovation modes and the dynamic interactions among the technology capability, innovation modes, market formation, and wind energy policy. The innovation mode in China began with imitative innovation, then transitioned to cooperative innovation, and has more recently set its sights on attaining truly indigenous innovation. Public policy serves as a key driving force for the evolution of innovation modes, as well as the development of the market. The policy focus has evolved in the following sequence: 1. building the foundation for technological innovation; 2. encouraging technology transfer; 3. enhancing local R and D and manufacturing capabilities; 4. enlarging the domestic market; and 5. cultivating an open environment for global competition and sustainable market development in China. - Highlights: ► New data were provided for China’s wind turbine manufacturing industry. ► The transition of innovation modes in the industry is reviewed. ► The interaction among the technology, market, policy, and innovation mode is explored. ► Public policies are the key driving forces for the transition.

A robust body of research has identified school transitions during adolescence, and in particular the transition from middle to high school, as one of the riskiest phases for school failure, being characterized by significant social, emotional and behavioral changes. This transition is critical even with respect to academic achievement: in Italy, the highest frequency of school dropout can be observed in the 9th and 10th grades, partly as a consequence of poor adjustment to the new school context. The impact of students' relationships with their teachers may be particularly relevant during critical developmental periods. Indeed, student-teacher relationships have been widely recognized as protective factors in school adjustment and, in case of negative relationships, also as a factor that increases the risk of maladjustment. Positive and affective student-teacher relationships may play an important role in students' adaptation to the school environment, favoring both academic achievement and adaptive behaviors. The aim of this study was to investigate the effects of the quality of teacher-student relationships, as perceived by pupils, on academic achievement, and problem and prosocial behaviors during the relevant school transition. The sample consisted of 122 students (55% female). We employed a self-report questionnaire to collect information on: demographic characteristics, quality of the relationship with teachers, problem and prosocial behaviors, and academic achievement. Students filled in the questionnaires twice: once during the 8th grade and 1 year later, during their first year of high school (9th grade). Regression analyses indicated that both average and varying levels of closeness with teachers significantly predicted changes in academic achievement: A perceived increase in closeness in 9th grade, as well as a higher mean closeness level, was associated with an increase in academic achievement. In turn, an increase in the level of perceived conflict

2014-12-01

Full Text Available This paper integrates several streams of literature in transition management and proposes a holistic framework for its application in policy-making. Separate fields of study, such as motors of change and strategic intelligence tools, are unified in a single analytical process. The process involves five steps that may be repeated until a desired policy objective is achieved. The pilot, integrated technology roadmap process that has been launched in Turkey is analyzed as a case study. The Energy Efficiency Technology Roadmap has been completed with the participation of over 160 experts in 5 different stages. It involved the collection of over 349 Delfi statements, their consolidation for a Delfi survey with 16 statements, the analysis of the results, a focal group meeting to develop roadmaps for the 7 selected goals, and the consultation of the roadmaps to the sector. The paper concludes that an integrated technology roadmap process, as described in the pilot case study, provides an advanced version of transition management, which is needed to mobilize research, development, and innovation for sustainable development.

Although adoptive family research has increased, most has focused on childhood and adolescence. Despite the known importance of parent-adolescent relationships drawn from the general population, we know little about how adoptive family relationships change or remain the same as adopted adolescents enter young adulthood. Using the Sibling Interaction and Behavior Study, the purpose of this study was to build on previous research to explore differences in conflict, closeness, and relationship quality between adoptive and nonadoptive families during the transition from late adolescence into young adulthood. Self-report and independent observations were collected from children, mothers, and fathers at late adolescence (range: 14.50-18.49 years) and young adulthood (range:18.50-22.49 years), and analyzed using within-subjects repeated measures. Although adoptive family dyads had lower relationship indicators than nonadoptive family dyads, similar trends over time occurred for both family types. Using individuation theory, we suggest individuation occurs for both types of families, with adoptees facing unique additional challenges during this process, including integration of adoption status, adoption communicativeness, adoption information seeking, and relationship with birth parents as possible influences in this process.

In 87 randomly selected diabetic patients (67 type 1, 20 type 2) and 25 control subjects, gastric emptying of digestible solid and liquid meals and oesophageal transit of a solid bolus were measured with scintigraphic techniques. Gastrointestinal symptoms, autonomic nerve function and glycaemic control were evaluated in the diabetic patients. Gastric emptying and oesophageal transit were slower (P<0.001) in the diabetic patients compared with the control subjects, and both were delayed in about 40% of them. There was a relatively weak (r=0.32; P<0.01) relationship between solid and liquid gastric emptying, and no significant correlation (r=0.11, NS) between oesophageal transit and gastric emptying of the solid meal. Scores for upper gastrointestinal symptoms and autonomic nerve function correlated weakly (r=0.21; P<0.05) with both oesophageal transit and gastric emptying. Gastric emptying of the liquid meal was slower (P<0.05) in patients with blood glucose concentrations >15 mmol/l. These results indicate that gastric emptying in patients with diabetes mellitus should be assessed by liquid as well as by solid test meals and that oesophageal transit should not be used as a predictor of generalised diabetic gastroenteropathy.

Cities concentrate populations, consumptions, levers of actions, and are places of various experiments for energy transition. This book aims at giving an overview of possible scenarios of development of renewable energies in urban context. It is based on interviews of actors of the energy, building and urban planning sectors by researchers in town planning, management, technology, political and economic sciences. The authors examine what would occur if large companies would manage entire quarters, if local authorities would supervise production and supply, if the State would take control of all fields of action again, or if consumer cooperatives would exchange energy and pool productions. In its different chapters, the book presents four scenarios of energy coordination in urban context by 2040, discuss energy transition in urban spaces, discuss the perspectives of evolution towards more autonomous cities and quarters from an energetic point of view, and discuss business models and urban energetic innovations

Masculinity and Material Culture in Technological Transitions: From Letterpress to Offset Lithography, 1960s-1980s.

Science.gov (United States)

Stein, Jesse Adams

Between the 1960s and the 1980s the printing industry in advanced capitalist economies underwent dramatic technological change. While the transition from "hot metal" compositing to computerized typesetting has been extensively analyzed, there was another transformation occurring simultaneously: in the pressroom, letterpress was gradually replaced by offset lithography. Many letterpress machinists retrained, moving from a heavy, manual technology (with an entrenched patriarchal culture) to a method that was faster and less physically taxing. However, unlike their compositor counterparts, the press-machinists' transition involved a continuity of traditional masculine craft identities rather than a rupture associated with "deskilling." Intrinsic to this experience of technological change was a masculine embodiment that was attuned to and shaped by the materiality and aesthetics of printing technologies. This article establishes how masculine craft identities do not rely exclusively on skill-based mastery of traditional technologies, but also relate to other dimensions of technology, such as aesthetics, embodied "know-how," and the physicality of industrial machinery.

This report examines the activities of a major commercial air carrier between 1993 and late 1996 as it acquired an advanced fleet of high-technology aircraft (Boeing 757). Previously, the airline's fleet consisted of traditional (non-glass) aircraft, and this report examines the transition from a traditional fleet to a glass one. A total of 150 pilots who were entering the B-757 transition training volunteered for the study, which consisted of three query phases: (1) first day of transition training, (2) 3 to 4 months after transition training, and (3) 12 to 14 months after initial operating experience. Of these initial 150 pilots, 99 completed all three phases of the study, with each phase consisting of probes on attitudes and experiences associated with their training and eventual transition to flying the line. In addition to the three questionnaires, 20 in-depth interviews were conducted. Although the primary focus of this study was on the flight training program, additional factors such as technical support, documentation, and training aids were investigated as well. The findings generally indicate that the pilot volunteers were highly motivated and very enthusiastic about their training program. In addition, the group had low levels of apprehension toward automation and expressed a high degree of satisfaction toward their training. However, there were some concerns expressed regarding the deficiencies in some of the training aids and lack of a free-play flight management system training device.

A main concern that remains with the continued growth of online nursing education programs is the way educator and student relationships can be affected by new technologies. This interpretive study aims to gain an understanding of how technology influences the development of interpersonal relationships between the student and faculty in a virtual learning environment. Using an established structured approach to qualitative metasynthesis, a search was conducted using PubMed, EBSCO, CINAHL, Medline, ProQuest, Ovid Nursing databases, and Google Scholar, focused on caring and relational aspects of online nursing education. Technology alters communication, thereby positioning the intentionality of the educator at the heart of interpersonal relationship development in virtual learning spaces. This interpretive synthesis of prior qualitative research supports the development of a framework for online nursing courses, the need for continuing education of nursing faculty, the value of caring intentions, and enhancement of the educator's technological proficiency.

2018-01-24

The changes in the mechanical properties of a cell are not only the cause of some diseases, but can also be a biomarker for some disease states. In recent times, microfluidic devices with built-in constrictions have been widely used to measure these changes. The transit time in such devices, defined as the time that a cell takes to pass through a constriction, has been found to be a crucial factor associated with the cell mechanical properties. Here, we use smoothed dissipative particle dynamics (SDPD), a particle-based numerical method, to explore the relationship between the transit time and mechanical properties of a cell. Three expressions of the transit time are developed from our simulation data, with respect to the stenosed size of constrictions, the shear modulus and bending modulus of cells, respectively. We show that a convergent constriction (the inlet is wider than the outlet), and a sharp-corner constriction (the constriction outlet is narrow) are better in identifying the differences in the transit time of cells. Moreover, the transit time increases and gradually approaches a constant as the shear modulus of cells increases, but increases first and then decreases as the bending modulus increases. These results suggest that the mechanical properties of cells can indeed be measured by analyzing their transit time, based on the recommended microfluidic device.

Koperwas, K.; Grzybowski, A.; Grzybowska, K.; Wojnarowska, Z.; Paluch, M.

2015-01-01

In this paper, we define and experimentally verify thermodynamic characteristics of the liquid-glass transition, taking into account a kinetic origin of the process. Using the density scaling law and the four-point measure of the dynamic heterogeneity of molecular dynamics of glass forming liquids, we investigate contributions of enthalpy, temperature, and density fluctuations to spatially heterogeneous molecular dynamics at the liquid-glass transition, finding an equation for the pressure coefficient of the glass transition temperature, dTg/dp. This equation combined with our previous formula for dTg/dp, derived solely from the density scaling criterion, implies a relationship among thermodynamic coefficients at Tg. Since this relationship and both the equations for dTg/dp are very well validated using experimental data at Tg, they are promising alternatives to the classical Prigogine-Defay ratio and both the Ehrenfest equations in case of the liquid-glass transition

Weisskirch, Robert S; Delevi, Raquel

2012-09-01

Relationship dissolution now occurs through technologies like text messaging, e-mail, and social networking sites (SNS). Individuals who experience relationship dissolution via technology may differ in their attachment pattern and gender role attitudes from those who have not had that experience. One hundred five college students (males=21 and females=84) completed an online questionnaire about technology-mediated breakups, attachment style, and gender role attitudes. More than a quarter of the sample had experienced relationship dissolution via technology. Attachment anxiety predicted those subject to technology-mediated breakups. Attachment avoidance and less traditional gender roles were associated with increased likelihood of technology use in relationship dissolution. Implications are discussed in regards to future research and practice.

Information technology deployment in a transition economy: Results from Slovenia

Directory of Open Access Journals (Sweden)

Hovelja Tomaž

2009-01-01

Full Text Available Information technology (IT is increasingly establishing itself as one of the major topics of study in the OECD area. The resulting OECD studies found that IT has an enormous productive potential; however before an economy can gain most of IT's benefits, several challenges need to be successfully addressed. The key challenges these studies identified are adequate organizational transformations of the enterprises and adequate reorganization of key national institutions. How these two challenges are tackled by the economies that are going through the transition from a socialist towards a coordinated/liberal market economy is, unfortunately, not equally well documented. To improve this situation in this paper I present new findings from one transition economy concerning the issues that the developed OECD countries already highlighted as critical for the successful deployment of IT, and issues that seem specific to the transition environments. The presented findings are based on the study I conducted into 94 enterprises, representing the population of the 914 biggest added value generating enterprises in Slovenia. This article thus tries to allow Slovenia and other economies in a similar situation to draw broad and important conclusions with managerial and political implications on how to deploy all available IT potential.

Understanding Students' Transition to High School: Demographic Variation and the Role of Supportive Relationships.

Benner, Aprile D; Boyle, Alaina E; Bakhtiari, Farin

2017-10-01

The transition to high school is disruptive for many adolescents, yet little is known about the supportive relational processes that might attenuate the challenges students face as they move from middle to high school, particularly for students from more diverse backgrounds. Identifying potential buffers that protect youth across this critical educational transition is important for informing more effective support services for youth. In this study, we investigated how personal characteristics (gender, nativity, parent education level) and changes in support from family, friends, and school influenced changes in socioemotional adjustment and academic outcomes across the transition from middle to high school. The data were drawn from 252 students (50% females, 85% Latina/o). The results revealed declines in students' grades and increases in depressive symptoms and feelings of loneliness across the high school transition, with key variation by student nativity and gender. Additionally, stable/increasing friend support and school belonging were both linked to less socioemotional disruptions as students moved from middle to high school. Increasing/stable school belonging was also linked to increases in school engagement across the high school transition. These findings suggest that when high school transitions disrupt supportive relationships with important others in adolescents' lives, adolescents' socioemotional well-being and, to a lesser extent, their academic engagement are also compromised. Thus, in designing transition support activities, particularly for schools serving more low-income and race/ethnic minority youth, such efforts should strive to acclimate new high school students by providing inclusive, caring environments and positive connections with educators and peers.

Leaving patients to their own devices? Smart technology, safety and therapeutic relationships.

Science.gov (United States)

Ho, Anita; Quick, Oliver

2018-03-06

This debate article explores how smart technologies may create a double-edged sword for patient safety and effective therapeutic relationships. Increasing utilization of health monitoring devices by patients will likely become an important aspect of self-care and preventive medicine. It may also help to enhance accurate symptom reports, diagnoses, and prompt referral to specialist care where appropriate. However, the development, marketing, and use of such technology raise significant ethical implications for therapeutic relationships and patient safety. Drawing on lessons learned from other direct-to-consumer health products such as genetic testing, this article explores how smart technology can also pose regulatory challenges and encourage overutilization of healthcare services. In order for smart technology to promote safer care and effective therapeutic encounters, the technology and its utilization must be safe. This article argues for unified regulatory guidelines and better education for both healthcare providers and patients regarding the benefits and risks of these devices.

Energy access and transition to cleaner cooking fuels and technologies in Sri Lanka: Issues and policy limitations

International Nuclear Information System (INIS)

Wickramasinghe, Anoja

2011-01-01

Easy energy access is a trigger for human, social, and economic development. A research project was undertaken in Sri Lanka to broaden the understanding of human dimension of energy access and technologies. A questionnaire survey, covering 2269 households, gathered data on socio-economic contexts and issues influencing a transition towards clean cooking facilities. The findings reveal that the transition is impeded by four factors: the lack of motivation and the pressure for switching over to cleaner facilities, the lack of modern energy technology options, the financial risks, and the lack of financing and other support. The paper describes the delicate two-way interrelation between women earning wages and the transitions to cleaner cooking fuels and technologies. The findings suggest the need for a policy framework involving the stakeholders, financing and standardised technologies. To make a change it is proposed to introduce a national, integrated policy incorporating financing and energy governance. - Highlights: ► Households in Sri Lanka lack access to modern energy technology options for cooking. ► Cooking with fuel wood and residues is the norm in Sri Lanka, particularly in rural households. ► A survey of rural households revealed that most cannot afford to switch to cleaner cooking options. ► Most households have little awareness of the health impacts of biomass cooking. ► Women in regular formal employment are more likely to value cleaner cooking options that save time.

Full Text Available Cities, and the networked infrastructures that sustain urban life, are seen as crucial sites for creating more sustainable futures. Yet, although there are many plans, the realisation of sustainable urban infrastructures on the ground is uneven. To develop better ways of understanding why this is the case, the paper makes a conceptual contribution by engaging with current understanding of urban sustainability transitions, using urban sustainable mobility as a reference point. It extends these insights to argue that urban transitions are not about technological or social innovation per se, but about how multiple innovations are experimented with, combined and reconfigured in existing urban contexts and how such processes are governed. There are potentially many ways in which urban sustainable mobility can be reconfigured contextually. Innovation is in the particular form of reconfiguration rather than individual technologies. To make analytical sense of this multiplicity, a preliminary framework is developed that offers the potential to think about urban transitions as contextual and reconfigurational. We argue that there is a need to embrace multiplicity and to understand its relationships to forms of reconfiguration, through empirical exploration and further theoretical and conceptual development. The preliminary framework is a contribution to doing so and we set out future directions for research.

The present study employs discrete-time hazard regression models to investigate the relationship between student loan debt and the probability of transitioning to either marital or nonmarital first childbirth using the 1997 National Longitudinal Survey of Youth (NLSY97). Accounting for nonrandom selection into student loans using propensity scores, our study reveals that the effect of student loan debt on the transition to motherhood differs among white, black, and Hispanic women. Hispanic women holding student loans experience significant declines in the probability of transitioning to both marital and nonmarital motherhood, whereas black women with student loans are significantly more likely to transition to any first childbirth. Indebted white women experience only a decrease in the probability of a marital first birth. The results from this study suggest that student loans will likely play a key role in shaping future demographic patterns and behaviors.

Health care spending has risen steadily in most countries, becoming a concern for decision-makers worldwide. Commentators often point to new medical technology as the key driver for burgeoning expenditures. This paper critically appraises this conjecture, based on an analysis of the existing literature, with the aim of offering a more detailed and considered analysis of this relationship. Several databases were searched to identify relevant literature. Various categories of studies (eg, multivariate and cost-effectiveness analyses) were included to cover different perspectives, methodological approaches, and issues regarding the link between medical technology and costs. Selected articles were reviewed and relevant information was extracted into a standardized template and analyzed for key cross-cutting themes, ie, impact of technology on costs, factors influencing this relationship, and methodological challenges in measuring such linkages. A total of 86 studies were reviewed. The analysis suggests that the relationship between medical technology and spending is complex and often conflicting. Findings were frequently contingent on varying factors, such as the availability of other interventions, patient population, and the methodological approach employed. Moreover, the impact of technology on costs differed across technologies, in that some (eg, cancer drugs, invasive medical devices) had significant financial implications, while others were cost-neutral or cost-saving. In light of these issues, we argue that decision-makers and other commentators should extend their focus beyond costs solely to include consideration of whether medical technology results in better value in health care and broader socioeconomic benefits.

Very little work has been done so far to model, test, and understand the relationship between oil prices and EROI over time. This paper investigates whether a declining EROI is associated with an increasing oil price and speculates on the implications of these results on oil policy. A model of the relationship between EROI and oil market prices was developed using basic economic and physical assumptions and non-linear least-squares regression models to correlate oil production price with EROI using available data from 1954–1996. The model accurately reflects historical oil prices (1954–1996), and it correlates well with historical oil prices (1997–2010) if a linear extrapolation of EROI decline is assumed. As EROI declines below 10, highly non-linear oil price movements are observed. Increasing physical oil scarcity is already providing market signals that would stimulate a transition away from oil toward alternative energy sources. But, price signals of physical oil scarcity are not sufficient to guarantee smooth transitions to alternative fuel sources, especially when there is insufficient oil extraction technology development, a declining mark-up ratio, a non-linear EROI–cost of production relationship, and a non-linear EROI–price relationship. - Highlights: ► A model of the relationship between EROI and oil prices has been developed. ► As EROI declines below 10, highly non-linear oil price movements are expected. ► Physical oil scarcity provides market signals for a transition to alternatives. ► Scarcity price signals are insufficient for smooth transitions to alternatives.

A Study of the Relationship between Information Technology and Changes in Culture and Social Relationships

Full Text Available Information technology and its consequent virtual space are opening up a new sphere in psychological, sociological and cultural studies associated with the mutual effect of technology, culture and human beings in general, and the interaction of cyberspace and culture, identity and human relationships. Recent studies in this field should be examined at least to realize whether the psychological and social outcomes and the pathology of virtual spaces are the result of the overflow of problems and issues of society and the real space into virtual space, and to decide if the challenges and the social problems in question are due to the development and growth of electronic media and virtual space? While describing and explaining  the effect of culture, society and their consequent traditions on virtual spaces, relationships and their content, and examining the effect of virtual space on culture, social actions, identity, attitudes and individual and collective behavior, the present article stresses that considering the short history and the little experience of the interaction between human and information technology and virtual space, it seems too soon to speak decisively about the outcomes of information technology and virtual spaces. Therefore, two principles are suggested to be established in cultural and social research on cyberspace. First, in the study of virtual space, priorities should be identified correctly and one should not merely focus on the problems resulting from information and communication technology instead of dealing with fundamental issues. Second, both in the theoretical and the methodological aspects of studies on virtual space, in different social and cultural spheres, one cannot rely merely on traditional theories and method, and new methods, in terms of theory, methodology and tools, should be applied.

Surgical Weight Loss as A Life-changing Transition: The Impact of Interpersonal Relationships on Post-Bariatric Women BACKGROUND: Although women account for 80% of patients having bariatric surgery (BS), the complex psychosocial mechanisms that accompany this transformation process have not been well established. The purpose of this study is to explore the lived experience of women transitioning in their interpersonal relationships post BS. A semi-structured interview with four questions was used. Six women, from six to 12 months post BS, were interviewed. The interviews were recorded, transcribed and analyzed using thematic analysis. By seeking support systems prior to undergoing BS, adequate social support was received during their recovery period. Attending bariatric support group meetings and using social media were significant to these women's satisfactory recovery. Relationship adjustments were sometimes needed, but overall these women established fulfilling social lives. Within the first year post bariatric surgery, women began to gain emotional strength and inspire others to lose weight as well. By inquiring about the psychosocial concerns of women who have undergone BS, healthcare providers can provide a more practical wellness plan. Copyright © 2017. Published by Elsevier Inc.

This paper studies the transition to low carbon power systems in China. The methodology is built on the newly developed multi-level perspective (MLP) transitions, as well as literature on innovation systems. Three lines of thought on the transition process are integrated to probe the possible transition pathways in China's power sector. Five transition pathways, namely reproduction, transformation, substitution, reconfiguration, de-alignment/re-alignment and reconfiguration, with their possible technology options are presented. The requirements for a smart grid in the socio-technical transition process are addressed within the MLP framework. The paper goes further to propose an interactive framework for low carbon transition management in China. Representative technology options are appraised by employing innovation theory to demonstrate the logic of policy design within the framework. The work presented in this paper will be useful in informing policy-makers and other stakeholders in China and it may prove to be a valuable reference for other countries in energy transition management. - Highlights: ► The transition to low carbon power systems is studied from a multi-level perspective. ► Transition pathways with possible technology options are presented. ► An interactive framework is proposed for managing this transition. ► Representative technology options are appraised within the framework to show the logic of policy design.

Ryan, Cathryn T; Kramer, Jessica M; Cohn, Ellen S

2016-08-01

The purpose of this study was to examine the role of the self-disclosure process in regard to connection development and relationship quality in peer mentoring relationships between transition-age youth (ages 15-20) and young adults (ages 18-36) with intellectual and/or developmental disabilities. Self-disclosure is defined as "the disclosure of inner feelings and experiences to another person" that "fosters liking, caring, and trust, thereby facilitating the deepening of close relationships" ( Reis & Shaver, 1988 , p. 372). Nine peer mentoring dyads with varied interpersonal connections were purposefully selected from a larger intervention study. Recorded mentoring conversations were analyzed for self-disclosure content and peer mentor response. The findings demonstrated trends related to connection development and differences across degree of connection. In relationships with stronger connections, there was a higher quantity of self-disclosure and more frequent disclosure of emotions, and peer mentors responded more frequently with advice and reciprocated self-disclosure. Implications of findings for promoting higher-quality peer mentoring relationships are discussed.

We propose a model of technological transitions based on two different types of innovations. Branching innovations refer to technological improvements along a particular path, while recombinant innovations represent fusions of multiple paths. Recombinant innovations create “short-cuts” which reduce switching costs allowing agents to escape a technological lock-in. As a result, recombinant innovations speed up technological progress allowing transitions that are impossible with only branching ...

2012-11-01

Full Text Available Social networks analysis applied to rural innovation processes becomes a very useful technology transfer tool, since it helps to understand the complexity of social relationships among people and/or institutions in their environment, and it also defines those innovation networks given in specific working groups or regions. This study was conducted from April to May 2011 to determine those networks and key players present in the group of growers associated as “Productora y Comercializadora de Papaya de Cotaxtla S.P.R. de R.L.”, that influence the technology transfer process in Cotaxtla, Veracruz, Mexico. Data were analyzed using UCINET 6 software. Three centrality measures were obtained: range, degree of mediation and closeness. Of 32 network players, 27 actively diffuse innovations according to their interests; alliances must be established with them to transfer technology. Four growers stand out as central actors, which along with the Instituto Nacional de Investigaciones Forestales Agricolas y Pecuarias, the Colegio de Postgraduados and the growers’ organization itself, could be the most appropriate actors to establish a technology transfer program to accelerate the diffusion and adoption of innovations. Wholesalers, middlemen and credit institutions do not participate in this process, but having capital they could be incorporated in the innovation diffusion process.

Close relationship between a dry-wet transition and a bubble rearrangement in two-dimensional foam

Science.gov (United States)

Furuta, Yujiro; Oikawa, Noriko; Kurita, Rei

2016-01-01

Liquid foams are classified into a dry foam and a wet foam, empirically judging from the liquid fraction or the shape of the gas bubbles. It is known that physical properties such as elasticity and diffusion are different between the dry foam and the wet foam. Nevertheless, definitions of those states have been vague and the dry-wet transition of foams has not been clarified yet. Here we show that the dry-wet transition is closely related to rearrangement of the gas bubbles, by simultaneously analysing the shape change of the bubbles and that of the entire foam in two dimensional foam. In addition, we also find a new state in quite low liquid fraction, which is named “superdry foam”. Whereas the shape change of the bubbles strongly depends on the change of the liquid fraction in the superdry foam, the shape of the bubbles does not change with changing the liquid fraction in the dry foam. Our results elucidate the relationship between the transitions and the macroscopic mechanical properties. PMID:27874060

Information technology as a facilitator of suppliers’ collaborative communication, network governance and relationship longevity in supply chains

Directory of Open Access Journals (Sweden)

Richard Chinomona

2013-08-01

Full Text Available There is an increasing awareness about the paramount importance of information technology within business in the context of large businesses. However, research about the investigation of the role of information technology resources in fostering collaborative communication, network governance and relationship longevity in the small and medium enterprise sector has remained scant. The primary objective of this study was to investigate the influence of information technology on collaborative communication, network governance and relationship longevity in Zimbabwe’s SME sector. Five research hypotheses were posited and sample data from 162 small and medium enterprise suppliers were collected and used to empirically test the hypotheses. The results of this study showed that information technology resources positively influenced small and medium enterprise suppliers’ collaborative communication, network governance and consequential relationship longevity with their buyers in a significant way. Overall, the current study findings provided tentative support to the proposition that information technology resources, collaborative communication and network governance should be recognised as significant antecedents for improved relationship longevity between suppliers and their buyers in the SME setting. Therefore, managers in the small and medium enterprise sector and small and medium enterprise owners need to pay attention to both collaborative communication and network governance in order to optimise information technology resource impact on their relationship longevity with their business counterparts. Limitations and future research directions were also indicated.

How Economic Disadvantage Affects the Availability and Nature of Mentoring Relationships During the Transition to Adulthood.

Raposa, Elizabeth B; Erickson, Lance D; Hagler, Matthew; Rhodes, Jean E

2018-03-01

Supportive nonparental adults, particularly nonfamilial adults, provide critical support during the transition to adulthood, opening doors to educational and career paths. This study examined whether economic disadvantage shapes access to these relationships. Results showed that low-income adolescents had reduced access to naturally occurring mentors, and the relationships they did form tended to be close bonds with family and friends, rather than nonfamilial adults. Their mentors were more likely to focus on practical support, and less likely to serve as role models or provide career advice. These effects of socioeconomic status on natural mentoring relationships remained evident, even when accounting for youth race/ethnicity. Findings suggest that networks of support differ depending on a youth's socioeconomic context in ways that could perpetuate social and economic inequalities. © Society for Community Research and Action 2018.

Explaining environmental Kuznets curves. How pollution induces policy and new technology

International Nuclear Information System (INIS)

Smulders, S.; Bretschger, L.

2000-01-01

Production often causes pollution as a by-product. Once pollution problems become too severe, regulation is introduced by political authorities which forces the economy to make a transition to cleaner production processes. We model this transition as a change in 'general purpose technology' (GPT) and investigate how it interferes with economic growth driven by quality-improvements. The model gives an explanation for the inverted U-shaped relationship found in empirical research for many pollutants, often referred to as the Environmental Kuznets Curve (EKC). We provide an analytical foundation for the claim that the rise and decline of pollution can be explained by policy-induced technology shifts. 19 refs

Menéndez, Susana; Hidalgo, M Victoria; Jiménez, Lucía; Moreno, M Carmen

2011-11-01

Research into the process of becoming mother or father shows very conclusively that this important life transition is accompanied by both a decrease in marital quality and a more traditional division of labour. In this paper these changes are analyzed with special emphasis on the relationships between them and exploring the role played in this process by the mother's work status. Results showed a significant link between the development of marital quality and violated expectations regarding father involvement on childrearing. Dual-earner families were characterized by a specific pattern of changes, with greater stability than single-earner families in marital and parental roles during transition to parenthood and a significant role played by spouse support as a partner, but not as a parent.

The principal aim was twofold: 1 to verify how relational support and style of decision making - respectively markers of family connectedness and autonomy - change from adolescence to young adulthood; 2 to compare the perceptions of parents and children through a measure of agreement. The sample was composed of 259 Italian families with a child between 17 and 25 years of age. Participants filled out a self report questionnaire including the Parent-Adolescent Support Scale and the Style of Decision Making Scale. Results highlighted that children perceived a significant increase in relational support and in autonomy from late adolescence to young adulthood. Furthermore, agreement between parents and children increased by aging. Therefore, near the transition to adulthood, parents and young adults are closer to each other than during late adolescence.

Borowski, Stanley K.; McCurdy, David R.; Packard, Thomas W.

The "fast conjunction" long surface stay mission option was selected for NASA's recent Mars Design Reference Architecture (DRA) 5.0 study because it provided adequate time at Mars (approx. 540 days) for the crew to explore the planet's geological diversity while also reducing the "1-way" transit times to and from Mars to approx. 6 months. Short transit times are desirable in order to reduce the debilitating physiological effects on the human body that can result from prolonged exposure to the zero-gravity (0-gE) and radiation environments of space. Recent measurements from the RAD detector attached to the Curiosity rover indicate that astronauts would receive a radiation dose of approx. 0.66 Sv (approx. 66 rem)-the limiting value established by NASA-during their 1-year journey in deep space. Proven nuclear thermal rocket (NTR) technology, with its high thrust and high specific impulse (Isp approx. 900 s), can cut 1-way transit times by as much as 50 percent by increasing the propellant capacity of the Mars transfer vehicle (MTV). No large technology scale-ups in engine size are required for these short transit missions either since the smallest engine tested during the Rover program-the 25 klbf "Pewee" engine is sufficient when used in a clustered arrangement of three to four engines. The "Copernicus" crewed MTV developed for DRA 5.0 is a 0-gE design consisting of three basic components: (1) the NTP stage (NTPS); (2) the crewed payload element; and (3) an integrated "saddle truss" and LH2 propellant drop tank assembly that connects the two elements. With a propellant capacity of approx. 190 t, Copernicus can support 1-way transit times ranging from approx. 150 to 220 days over the 15-year synodic cycle. The paper examines the impact on vehicle design of decreasing transit times for the 2033 mission opportunity. With a fourth "upgraded" SLS/HLV launch, an "in-line" LH2 tank element can be added to Copernicus allowing 1-way transit times of 130 days. To achieve 100

Care coordination and transitional care services are strategically important for achieving the priorities of better care, better health, and reduced costs embodied in the National Strategy for Quality Improvement in Health Care (National Quality Strategy [NQS]). Some of the most vulnerable times in a person’s care occur with changes in condition as well as movement within and between settings of care. The American Academy of Nursing (AAN) believes it is essential to facilitate the coordination of care and transitions by using health information technology (HIT) to collect, share, and analyze data that communicate patient-centered information among patients, families, and care providers across communities. HIT makes information accessible, actionable, timely, customizable, and portable. Rapid access to information also creates efficiencies in care by eliminating redundancies and illuminating health history and prior care. The adoption of electronic health records (EHRs) and information systems can enable care coordination to be more effective but only when a number of essential elements are addressed to reflect the team-based nature of care coordination as well as a focus on the individual’s needs and preferences. To that end, the AAN offers a set of recommendations to guide the development of the infrastructure, standards, content, and measures for electronically enabled care coordination and transitions in care as well as research needed to build the evidence base to assess outcomes of the associated interventions.

A Transitive Recommendation System for Information Technology Communities

Full Text Available Social networks have become a new trend for research among computer scientist around the world. Social network had an impact on users' way of life. One of social network usages is recommendation systems. The need of recommendation systems is arising when users try to know best choice for them in many items types (books, experts, locations, technologies...etc. The problem is that a single person can't try all alternatives in all possibles life goals to compare. Thus, a person has to use his friends' expertise to select better option in any item category. This process is the main idea of “Recommendation Systems”. Recommendation systems usually depend on users-to-items ratings in a network (graph. Two main challenges for recommendation systems are accuracy of recommendation and computation size. The main objective of this paper is to introduce a suggested technique for transitive recommendation system based on users' collaborative ratings, and also to balance loading of computation. All this has to be applied on a special type of social network. Our work studied the transitivity usage in connections to get a relation (path as a recommendation for nodes not directly connected. The target social network has eight types of nodes. So, there are techniques that are not suitable to this complex type of network. Those we can present a new support for recommending items of several types to users with several types. We believe that this functionality hasn't been fully provided elsewhere. We have suggested using single source shortest path algorithm combined with Map Reduce technique, and mathematically deduced that we have a speeding up of algorithm by 10% approximately. Our testing results shows an accuracy of 89% and false rejection of 99% compared to traditional algorithms with less configuration parameters and more steady count of recommendations.

Examining hydrogen transitions.

Energy Technology Data Exchange (ETDEWEB)

Plotkin, S. E.; Energy Systems

2007-03-01

This report describes the results of an effort to identify key analytic issues associated with modeling a transition to hydrogen as a fuel for light duty vehicles, and using insights gained from this effort to suggest ways to improve ongoing modeling efforts. The study reported on here examined multiple hydrogen scenarios reported in the literature, identified modeling issues associated with those scenario analyses, and examined three DOE-sponsored hydrogen transition models in the context of those modeling issues. The three hydrogen transition models are HyTrans (contractor: Oak Ridge National Laboratory), MARKAL/DOE* (Brookhaven National Laboratory), and NEMS-H2 (OnLocation, Inc). The goals of these models are (1) to help DOE improve its R&D effort by identifying key technology and other roadblocks to a transition and testing its technical program goals to determine whether they are likely to lead to the market success of hydrogen technologies, (2) to evaluate alternative policies to promote a transition, and (3) to estimate the costs and benefits of alternative pathways to hydrogen development.

Effects of long-term coal supply contracts on technology adoption and improvements in the mining of coal. Final technical report

Energy Technology Data Exchange (ETDEWEB)

Walton, D.R.; Hawkins, S.A.; Webb, P.F.; Kauffman, P.W.

1979-08-01

The relationship between long-term coal supply contracts and the adoption of new technology in the coal mining industry is a complex one. From this study certain conclusions can be drawn. New technologies and improvements in the mining of coal can be logically categorized into three areas: evolutionary technology, transitional technology, or innovative technology. Evolutionary improvements in technology can be categorized as improvements, or increased production capacities, in existing equipment. Transitional technology involves the adoption of existing or proven technologies into new conditions, or, proceeding from one technology type to a newer type for the same function. Innovative technology includes equipment, concepts, and systems not readily available, or untried, in the existing mining environment (seam conditions, etc.). Technology adoption is an economic decision. This point was repeatedly emphasized by industry representatives contacted during the study. The long-term coal supply contract influences the decision to adopt new technology and mining improvements in several ways depending on the technology type (i.e., evolutionary, transitional, or innovative), and also the coal supplier type (i.e., captive or independent producer). Several examples of the adoption of new technologies in mines under long-term coal supply contracts are discussed. (LTN)

Parent-child relationship is created already in prenatal fantasies and expectations of the child-to-be. Negative violation of these expectations after the child is born is known to be harmful for the parent-child relationship. Yet, research is scarce about the medical and psychological factors contributing to violated expectations (VE). This study models the role of parent-, delivery- and infant-related underlying mechanisms for VE. It further compares parents with assisted reproductive treatment (ART) and spontaneous conception (SC), and primi- and multiparous couples. The couples (n = 743) separately filled in questionnaires concerning their prenatal expectations (T1) and 2 months postnatal representations (T2) of intimacy and autonomy in the relationship with their child, measured with Subjective Family Picture Test. A negative or positive discrepancy indicated violated expectations. The parent-related (mental health and marital quality), delivery-related (maternal and paternal birth experience, unplanned Caesarean, and amount of analgesia) and infant-related (infant health problems, difficult infant characteristics, and parental worry) factors were assessed at T2. Results show that among mothers, the associations were mostly indirect and mediated via mental health problems. Among fathers, the associations were direct, marital problems most crucially predicting VE. ART fathers were less susceptible to VE resulting from infant-related problems than SC fathers, but more susceptible to VE resulting from delivery problems. Delivery- and infant-related factors also predicted VE differently among primi- and multiparous mothers. Considering factors that contribute to VE is important when working with couples in transition to parenthood. PsycINFO Database Record (c) 2014 APA, all rights reserved.

From biological neural networks to thinking machines: Transitioning biological organizational principles to computer technology

Science.gov (United States)

Ross, Muriel D.

1991-01-01

The three-dimensional organization of the vestibular macula is under study by computer assisted reconstruction and simulation methods as a model for more complex neural systems. One goal of this research is to transition knowledge of biological neural network architecture and functioning to computer technology, to contribute to the development of thinking computers. Maculas are organized as weighted neural networks for parallel distributed processing of information. The network is characterized by non-linearity of its terminal/receptive fields. Wiring appears to develop through constrained randomness. A further property is the presence of two main circuits, highly channeled and distributed modifying, that are connected through feedforward-feedback collaterals and biasing subcircuit. Computer simulations demonstrate that differences in geometry of the feedback (afferent) collaterals affects the timing and the magnitude of voltage changes delivered to the spike initiation zone. Feedforward (efferent) collaterals act as voltage followers and likely inhibit neurons of the distributed modifying circuit. These results illustrate the importance of feedforward-feedback loops, of timing, and of inhibition in refining neural network output. They also suggest that it is the distributed modifying network that is most involved in adaptation, memory, and learning. Tests of macular adaptation, through hyper- and microgravitational studies, support this hypothesis since synapses in the distributed modifying circuit, but not the channeled circuit, are altered. Transitioning knowledge of biological systems to computer technology, however, remains problematical.

Relocation for the purpose of receiving care may be one of the more challenging transitions for older adults. The purpose of this study was to facilitate a family life review (FLR) session aimed at enhancing family relationships and assisting older adults in coping with the challenges associated with a relocation. Fourteen dyads comprised of older adults who relocated to an assisted living facility (ALF) and a chosen family member or friend participated in a FLR session and semi-structured follow up interview. Data were analyzed using the constant comparative method and triangulated with descriptive statistics. Emergent themes suggested participating in FLR influenced families by raising emotions, systemically thinking, and navigating the relocation. FLR facilitated positive connections, enhanced existing relationships, and promoted self-acceptance. Families indicated mutual storytelling was enjoyable and reminded them of the urgency to share their story. FLR allowed dyads to reflect and thus prompted a renewed perspective on some of the more challenging components of the relocation transition. Study findings provide insight into how families organize individual and interpersonal narratives and use these narratives during transitional times. FLR can aid families in making a smoother and fulfilling move to an ALF and other late life transitions.

2016-01-01

The emergence of Web 2.0 and Big Data technologies has allowed a new customer relationship strategy based on interactivity and collaboration called Social Customer Relationship Management (Social CRM) to be created. This enhances customer engagement and satisfaction. The implementation of Social CRM is a complex task that involves different organisational, human and technological aspects. However, there is a lack of methodologies to assist companies in these processes. This paper shows a novel methodology that helps companies to implement Social CRM, taking into account different aspects such as social customer strategy, the Social CRM performance measurement system, the Social CRM business processes, or the Social CRM computer system. The methodology was applied to one company in order to validate and refine it.

To describe the relationship between parents with gender identity disorder (GID) and their child(ren) as described by the parent and to understand how being a parent affects transitioning from one gender to the other. Fourteen parents with GID underwent a semi-structured interview and completed the Index of Parental Attitudes (IPA). An IPA score of greater than 30 indicates parent–child relationship difficulties (range 0–100). The authors also conducted the SCID-I to establish other Axis I disorders. We assessed 12 male to female and two female to male parents with GID residing in Ireland. In total, 14 GID parents had 28 children. Three children had no relationship with their GID parent. The other 25 children, as reported by the parent, had good relationships with their children. In addition, these 25 children average score IPA score was 6.4 (range 0–25). Twelve GID parents (86 %) believed that being a parent had no effect on their desired level of transitioning, while two were influenced not to transition. Eleven GID parents (79 %) reported that being a parent had increased the time taken to commence transitioning, two have stopped transitioning altogether, while one cited no effect on time. Parents with GID report positive relationships or no relationship with their children and the IPA revealed no clinical problems. Being a parent can prolong transitioning time in people with GID and can affect overall achieved level of transitioning.

2010-01-01

The efficient design of strategies for the long-term sustainability of nuclear energy or the phase-out of this technology is possible after the study of transition scenarios from the current fuel cycle to a future one with advanced technologies and concepts. CIEMAT has participated in numerous fuel cycle scenarios studies for more than a decade and, from some years ago, special attention has been put in the study of transition scenarios. In this paper, the main characteristics of each studied transition scenario are described. The main results and partial conclusions of each scenario are also analyzed. As general conclusions of transition studies, we highlight that the advantages of advanced technologies in transition scenarios can be obtained by countries or regions with sufficiently large nuclear parks, with a long-term implementation of the strategy. For small countries, these advantages are also accessible with an affordable cost, by means of the regional collaboration during several decades. (authors)

Communication technology is a central feature of young people's lives, but its role in romantic and sexual relationships has not been thoroughly examined. This article describes how young adults use communication technology for partnering across relationship stages (formation, maintenance, and dissolution) and types (serious/casual), and proposes implications of usage in relationships. This study analyzed qualitative data from a five-week, prospective, coital diary method with related debriefing interviews (N = 70) of African American and Puerto Rican men and women aged 18 to 25 years in Hartford and Philadelphia. Cell phones, including calls, text messaging, and mobile Internet, were the most common forms of communication technology used for partnering goals. Participants reported using cell phones to pursue partnering goals across all relationship stages, including formation (meeting, screening, and getting to know new partners), maintaining existing relationships, and breaking up. Cell phone uses depended on the type of relationship (serious/casual) and the participants' intentions and desires. Results indicated that cell phones are an important element of communication among young adults in romantic and sexual relationships. Specific features of cell phone communication shape the process and context of partnering. Future research should explore emerging communication technologies and implications for psychosocial development, dating violence, and sexual behavior.

Focusing on the case of the Active House standard in the building sector, I investigate experimental standards in three research papers examining the following dynamics......: (1) the relationship between commensuration and legitimacy in the formulation and diffusion of a standard’s specifications; (2) the role of awareness in standardizing green default rules to establish sustainable consumption in buildings; and (3) the significance of focus on humans in the development...... of technological standards for sustainable building. Launching from a critical realist social ontology, I collected ethnographic data on the Active House Alliance, its cofounder VELUX, and three of their demonstration building projects in Austria, Germany, and Belgium over the course of three years from 2013...

Technology-Based Communication and the Development of Interpersonal Competencies Within Adolescent Romantic Relationships: A Preliminary Investigation.

Science.gov (United States)

Nesi, Jacqueline; Widman, Laura; Choukas-Bradley, Sophia; Prinstein, Mitchell J

2017-06-01

This study investigated longitudinal associations between adolescents' technology-based communication and the development of interpersonal competencies within romantic relationships. A school-based sample of 487 adolescents (58% girls; M age  = 14.1) participated at two time points, one year apart. Participants reported (1) proportions of daily communication with romantic partners via traditional modes (in person, on the phone) versus technological modes (text messaging, social networking sites) and (2) competence in the romantic relationship skill domains of negative assertion and conflict management. Results of cross-lagged panel models indicated that adolescents who engaged in greater proportions of technology-based communication with romantic partners reported lower levels of interpersonal competencies one year later, but not vice versa; associations were particularly strong for boys. © 2016 The Authors.

Gerlach, Tanja M; Arslan, Ruben C; Schultze, Thomas; Reinhard, Selina K; Penke, Lars

2017-09-18

Although empirical research has investigated what we ideally seek in a romantic partner for decades, the crucial question of whether ideal partner preferences actually guide our mating decisions in real life has remained largely unanswered. One reason for this is the lack of designs that assess individuals' ideal partner preferences before entering a relationship and then follow up on them over an extended period. In the Göttingen Mate Choice Study (GMCS), a preregistered, large-scale online study, we used such a naturalistic prospective design. We investigated partner preferences across 4 preference domains in a large sample of predominantly heterosexual singles (N = 763, aged 18-40 years) and tracked these individuals across a period of 5 months upon a possible transition into romantic relationships. Attesting to their predictive validity, partner preferences prospectively predicted the characteristics of later partners. This was equally true for both sexes, except for vitality-attractiveness where men's preferences were more predictive of their later partners' standing on this dimension than women's. Self-perceived mate value did not moderate the preference-partner characteristics relations. Preferences proved to be relatively stable across the 5 months interval, yet were less stable for those who entered a relationship. Subgroup analyses using a newly developed indicator of preference adjustment toward (vs. away from) partner characteristics revealed that participants adjusted their preferences downward when partners fell short of initial preferences, but showed no consistent adjustment when partners exceeded them. Results and implications are discussed against the background of ongoing controversies in mate choice and romantic relationship research.

Students with Autism Spectrum Disorder and Their Parents in the Transition into Higher Education: Impact on Dynamics in the Parent-Child Relationship.

Science.gov (United States)

Van Hees, Valérie; Roeyers, Herbert; De Mol, Jan

2018-05-02

This study examined how 34 senior students and first-year college students with autism spectrum disorder, their mothers (n = 34) and fathers (n = 26) navigate the higher education transition, and how this context impacts on dynamics in the parent-child relationships. Semi-structured interviews were analyzed based on grounded theory and dyadic analysis principles. Both parties were confronted with an abundance of challenges and experienced strong feelings of ambivalence, stress and anxiety. Differences in perspectives occurred regarding the construction of adulthood, the acquisition of autonomy, disclosure and subscribing to support services. These differences caused tensions in the parent-child relationship, hindering the transformation of the relationship into an adult-like mutual relationship. Clinical implications are extrapolated on the basis of these findings.

Japanese economy has fallen into a long downturn called "The Lost Two Decades" after the collapse of bubble economy in early 1990s. Many companies could not gain competitive advantages although they conducted various management reforms to restore their competitiveness. The companies that have played the main role of the Japanese economy growth until then have lost the sustained competitive advantage. Moreover, they have struggled in the global market even now. On the other hand, Japanese automobile companies have high competitiveness and market share due to their advanced technology development. It is considered that personnel groups engaged in research and development of their companies cannot turn into core rigidity and the structure also hinders new core capabilities. In addition, there is a hypothesis that the close relationships with many suppliers contribute to acquisition of competitive advantage. Therefore, this paper focuses on the collaboration relationships with suppliers and core rigidity of human resources related to research and development as the analysis factors. First, we analyze the composition and core rigidity degree of human resources involved in technology development by social network analysis using patent information, which represents the research and development capability. Second, we analyze the degree of collaboration among companies based on the hypothesis that advanced technology development can be executed by joint research and developments with many kinds of suppliers. As a result, features of close collaboration with suppliers and high core rigidity rate in the Japanese automobile industry are clarified.

Full Text Available The Environmental Kuznets Curve (EKC introduces an inverted U-shaped relationship between environmental pollution and economic development. The inverted U-shaped curve is seen as complete pattern for developed economies. However, our study tests the EKC for developing transition economies of European Union, therefore, our results could make a significant contribution to the literature. In this paper, the relationship between carbon dioxide (CO2 emissions, gross domestic product (GDP, energy use and urban population is investigated in the Transition Economies (Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Slovenia. Environmental Kuznets Curve is tested by panel smooth transition regression for these economies for 1993 – 2010 periods. As a result of study, the null hypothesis of linearity was rejected and no-remaining nonlinearity test showed that there is a smooth transition exists between two regimes (below $5176 GDP per capita is first one and above $5176 GDP per capita is second one in the related period for these economies.

Relationship challenges and relationship maintenance activities following disclosure of transsexualism.

• Transsexual persons are increasing their visibility in society, and health care providers and others (such as social workers) will be called upon to help with issues that transsexual persons face. Challenges that face transsexual persons often include issues involving relationships. Psychiatric and mental health nurses and other caregivers can increase their therapeutic skills in working with couples that include transsexual persons by becoming aware of these challenges and subsequent activities that can help with them. • This research study looks at couple relationships in which one partner reveals male-to-female transsexual identity. These are relationships that were established as man-woman and now will transition into relationships that include a male-to-female person and a female partner. • Common challenges for these couples include issues related to: (1) sexual identity and relationship uncertainty; (2) male-to-female transition decision making; and (3) presenting in public. • Relationship maintenance activities that helped the couples in the study maintain and strengthen their relationships through these challenges include: (1) communication; (2) self-talk (for example, putting the situation in perspective); (3) social networks; (4) positive interactions; (5) impression management (for example, managing displays of affection in public); and (6) social activism. This qualitative study describes the relational dynamics that help sustain relationships of couples that include male-to-female transsexual persons (MTF) and their natal female partners (NF) following disclosure of transsexualism. Relationship challenges and relationship maintenance activities are identified. Each partner in 17 MTF-NF couples participated in individual surveys and interviews. The data were coded for themes related to relationship challenges and activities. MTF-NF couples experience challenges within the contexts of their relationships and of society. These challenges

Lin, Sunny C; Everson, Jordan; Adler-Milstein, Julia

2018-02-28

To assess whether the level of health information exchange (HIE) in U.S. hospitals is related to technology capabilities, incentives to exchange, or both. A total of 1,812 hospitals attesting to stage 2 of Medicare's Meaningful Use Incentive Program through April 2016. Hospital-level, multivariate OLS regression with state fixed effects was used to analyze the relationship between technology capability and incentives measures, and percent of care transitions with summary of care records (SCRs) sent electronically to subsequent providers. Stage 2 hospitals reported sending SCRs electronically for an average of 41 percent (median = 33 percent) of transitions. HIE level is related to four capability measures, one incentive measure, and one measure that is related to both capability and incentive. Percent of transitions with SCRs sent electronically was 3 percentage points higher (95 percent CI: 0.1-5.1) for hospitals with a third-party HIE vendor, 3 percentage points higher (95 percent CI: 0.5-5.4) for hospitals with an EHR vendor as their HIE vendor, and 3 percentage points higher (95 percent CI: 0.4-5.4) for hospitals that automatically alert primary care providers. The direction and statistical significance of the relationships between specific EHR vendor and electronic SCR transmission level varied by vendor. Nonprofits and government hospitals performed 5 percentage points higher (95 percent CI: 1.5-9.1) and 8 percentage points higher (95 percent CI: 3.4-12.3) than for-profits. Hospitals in systems performed 3 percentage points higher (95 percent CI: 0.8-6.1). The overall level of HIE is low, with hospitals sending an SCR electronically for less than half of patient transitions. Specific hospital characteristics related to both technology capabilities and incentives were associated with higher levels of HIE. © Health Research and Educational Trust.

The introduction of new technologies in mammography may improve image quality; however, it may unnecessarily increase doses if optimization processes are not studied. In this work, radiation doses of the moment of transition of conventional to digital mammography have been analyzed. The presented data have been acquired from 2005 to 2009, in hospitals and clinics of Sao Paulo city, to 4 conventional and 5 digital equipment. The results show that even after optimization processes, new technologies still impart higher doses. Thus, individualized studies are needed when technological transitions occur, in order to maintain image quality without significant dose increase. (author)

Full Text Available The recent advances on information technology have made tremendous change on traditional banking. These days, people do not carry cash and prefer to use electronic devices such as point of sale system (POS or PIN entry devices (PinPad to do desirable transactions. These technologies could facilitate e-business and increase profitability in various industries including banking sector. The purpose of this paper is to investigate the effect of five new products namely ATM, POS Machines, PinPad machines, online and swift branches on banking performance indicators including return on assets (ROA, return on equities (ROE and operating investment return (OIR. We use the information of 19 private and governmental banks, which were active in Iran over the period of 2005-2010. The study uses linear regression analysis as well as VAR technique to study the effects of the independent variables on bank performance indicators. The results indicate that while there are some weak and positive relationships between three technology indicators including POS, PinPad and online businesses and ROA as well as ROE, there is relatively strong and positive relationship between these three independent variables and OIR. In addition, while the results of VAR analysis have shown that any reduction on PinPad will reduce OIR but this reduction will disappear after approximately four periods.

This volume contains contributions resulting from an expert discussion on 'Technology Images and Concepts of Technology in Transition - an analysis in the philosophy of technology and general technology. This expert discussion took place on 6 October 2000 at the State Pedagogical Institute Brandenburg in Ludwigsfelde-Struveshof and was conceived and organized co-operatively by the Forschungszentrum Karlsruhe, Institute for Technology Assessment and Systems Analysis, the University of Potsdam, Institute for the Theory of Work/Technology and Professor Horst Wolffgramm, Frankfurt (Oder). It was the aim of the expert discussion to compile, compare and relate the various positions in the philosophy of technology, general technology science, the history of technology and the didactics of technology of the 'conceptualisation' of technology as a basis for generally understanding technology or for a scientifically based 'image of technology' to each other, and then to make them accessible for curricula within a framework of conceiving general technical education at all school levels. The contributions are grouped according to the two main foci of the event: On the one hand they are concerned with determining a contemporary concept of technology ('Image of technology'). One of the aims is to characterize technological change from the historical-genetic perspective and in this way to access technology as a work of mankind, as an important element of our culture. At the same time it is necessary to forecast future developments or to make future paths of development visible to enable the indication of change by basic innovations. Second, on this basis and supported by educational theory, conclusions are drawn for future-oriented technical general education for all students. The main focus in this is on the linkage between goals, content and subject-specific methods. In order to enable the determination of competence of any individual

Mr. Blademan. Macrolithic technology – Eneolithic vocabulary and metaphors

Directory of Open Access Journals (Sweden)

Aleksander Dzbyński

2011-12-01

Full Text Available The Eneolithic period witnessed a technological breakthrough of a significance comparable to that of the technological revolution in historical times, accompanied by a matching revolution in social and economic relationships. This transition no doubt led also to the creation of new and momentous metaphors, which in their turn triggered new senses and planes of communication. It goes without saying that the Eneolithic technology that had the greatest potential for metaphors promoting new ways of looking at the world was metallurgy. Nevertheless, before Eneolithic communities came to fully appreciate the properties of metal, many of their number resorted to an idiosyncratic flint technology to produce macrolithic implements. It seems that the production and exchange of macrolithic artefacts led to the development of a new vocabulary and grammar that served, among other things, to describe the social inequalities discernible in Eneolithic communities.

Divorce transitions: identifying risk and promoting resilience for children and their parental relationships.

Science.gov (United States)

Barnes, G G

1999-10-01

This paper gives an account of qualitative research linked to clinical work relating to some of the short-term effects of divorce on children within a British perspective. The transitions that accompany divorce and family reordering are shown by many studies in the United States, Australia, and New Zealand as well as in the United Kingdom to have stressful effects for children that can lead to long-term negative outcomes. Other studies have focused on the differential social and family factors that may contribute to the "differences that make a difference" to whether divorce has harmful effects on children. This paper describes clinical intervention into family relationships in divorcing and postdivorce families and suggests some high-risk issues for children. The focus of the work is one promoting long-term connections between parents and children in reordered+ families. Some interactions that may promote resilience in children as well as in their parents are alluded to briefly.

The Relationship Between Digital Technology Experience, Daily Media Exposure and Working Memory Capacity

Full Text Available Today’s youngsters interact with digital technologies to a great extent which leads scholars to question the influence of this exposure on human cognitive structure. Through resorting to digital nativity assumptions, it is presumed that cognitive architecture of the youth may change in accordance with digital technology use. In this regard, the current study investigated the relationship between digital technology experience, daily media exposure and working memory capacity of so-called digital native participants. A total of 572 undergraduate students responded to self-report measures, which addressed years of experience for 7 different digital devices and the daily time spent for 14 different digital activities. Participants’ working memory capacity was measured through the Computation Span and the Dot Matrix Test. While the former was used to measure the phonological loop capacity, the latter was used to address the visuo-spatial sketchpad capacity. Correlational analyses revealed that neither the phonological loop capacity nor the visuo-spatial sketchpad capacity was related to digital technology experience and daily media exposure. Thus, the transformative contribution of digital technology experience to human cognitive architecture could not be observed through the current measures

Progress in the research on phase transitions during Li + extraction/insertion processes in typical battery materials is summarized as examples to illustrate the significance of understanding phase transition phenomena in Li-ion batteries. Physical phenomena such as phase transitions (and resultant phase diagrams) are often observed in Li-ion battery research and already play an important role in promoting Li-ion battery technology. For example, the phase transitions during Li + insertion/extraction are highly relevant to the thermodynamics and kinetics of Li-ion batteries, and even physical characteristics such as specific energy, power density, volume variation, and safety-related properties.

IMPACT OF INFORMATION TECHNOLOGY (IT TOOLS, PARTNER RELATIONSHIP AND SUPPLY CHAIN PERFORMANCE

Directory of Open Access Journals (Sweden)

Ramayah T.

2008-01-01

Full Text Available This paper proposes a model that assesses the usage of information technology (IT tools, commitment of partner relationships, and supply chain performance in the Malaysian manufacturing industry. A total of 250 questionnaires were distributed to manufacturingcompanies located in Penang, which is in the northern region of Malaysia. Applying multiple regression analysis, the study indicated that a higher level of supply chain partner commitment leads to a higher level of supply chain reliability and flexibility. Trust among supply chain partners also contributes to improving supply chain flexibility. The study focused only on inter-organisational relationships. Future research should examine how both inter- and intra-organisational collaboration impact supply chain performance. Although researchers have recognised that IT is an enabler of supply chain management (SCM activities, there has been limited research that has directly associated the usage of IT and partner relationships to supply chain performance. This research is essential in order to ascertain the impact of IT usage and partnerrelationships on improving supply chain performance, particularly in the Malaysian manufacturing environment.

Energy transitions research: Insights and cautionary tales

International Nuclear Information System (INIS)

Grubler, Arnulf

2012-01-01

This short essay first reviews the pioneers of energy transition research both in terms of data as well as theories. Three major insights that have emerged from this nascent research fields are summarized highlighting the importance of energy end-use and services, the lengthy process of transitions, as well as the patterns that characterize successful scale up of technologies and industries that drive historical energy transitions. The essay concludes with cautionary notes also derived from historical experience. In order to trigger a next energy transition policies and innovation efforts need to be persistent and continuous, aligned, as well as balanced. It is argued that current policy frameworks in place invariably do not meet these criteria and need to change in order to successfully trigger a next energy transition towards sustainability. - Highlights: ► Includes the first literature review of early energy transition research. ► Summarizes three major research findings from the literature. ► Reviews policy implications of recent case studies of energy technology innovation. ► Argues that current policy frameworks are deficient in view of above lessons.

Fruity Batidas: The Technologies and Aesthetics of Kuduro

Directory of Open Access Journals (Sweden)

Garth Sheridan

2014-06-01

Full Text Available The interconnectedness of music technologies, studio innovation and dancing bodies is a key feature of electronic music cultures. An emerging scholarship by writers such as Butler and Tjora has bridged these studio and performance spaces, revealing the relationship between machine, music and party. This article considers the centrality of studio and performance technologies and techniques in the developing aesthetics of kuduro. I use interviews and observation of studio and performance practices to illustrate shifts within the genre and examine musical examples to highlight transitions. I argue that the increased availability of digital musical technologies in Angola shaped the development of kuduro through the 1990s and into the 2000s.  Furthermore, I argue that kuduro producers and performers have developed a range of aesthetic and performative practices that reflect social, material and technological restraints common to life in contemporary Angola. By examining interviews with kuduro practitioners and musical examples, this article sheds new light on the under examined aesthetics of kuduro. 

Personality-Relationship transaction in young adulthood.

Science.gov (United States)

Neyer, F J; Asendorpf, J B

2001-12-01

Personality and social relationships were assessed twice across a 4-year period in a general population sample of 489 German young adults. Two kinds of personality-relationship transaction were observed. First, mean-level change in personality toward maturity (e.g., increase in Conscientiousness and decrease in Neuroticism) was moderated by the transition to partnership but was independent of other developmental transitions. Second, individual differences in personality traits predicted social relationships much better than vice versa. Specifically, once initial correlations were controlled for, Extraversion, Shyness, Neuroticism, self-esteem, and Agreeableness predicted change in various qualities of relationships (especially with friends and colleagues), whereas only quality of relationships with preschool children predicted later Extraversion and Neuroticism. Consequences for the transactional view of personality in young adulthood are discussed.

Hanson, J. A.; Escher, W. J. D.

1979-01-01

The inevitability of an energy transition from today's non-renewable fossil base toward a renewable energy base is considered from the viewpoint of the need for a national transition strategy. Then, one such strategy is offered. Its technological building blocks are described in terms of both energy use and energy supply. The strategy itself is then sketched at four points in its implementation; (1) initiation, (2) early transition, (3) late transition, and (4) completion. The transition is assumed to evolve from a heavily natural gas-dependent energy economy. It then proceeds through its transition toward a balanced, hybrid energy system consisting of both centralized and dispersed energy supply technologies supplying hydrogen and electricity from solar energy. Related institutional, environmental and economic factors are examined briefly.

Entering primary school is an important childhood milestone, marking the beginning of a child's formal education. Yet the change creates a time of vulnerability for the child, the parents and the parent-child relationship. Failure to adjust to the transition may place the family in a psychologically devastating position. The aims of this study were to test the effectiveness of a parental training programme in enhancing the parent-child relationship and decreasing parental stress by reducing harsh parenting in preparing children for the transition to primary school. A randomised controlled trial incorporating a two-group pre-test and repeated post-test was conducted in one of the largest public housing estates in Hong Kong. A total of 142 parents were recruited, with 72 parents randomly assigned to the experimental group and 70 to the control group. Harsh parenting practices, parent-child relationships and parental stress were assessed. In comparison to parents in the control group, those in the experimental group engaged in less harsh parenting practices and reported better parent-child relationships. However, parental stress scores did not differ significantly between the two groups. This study addressed a gap in the literature by examining the effectiveness of the training programme for enhancing parent-child relationship and decreasing parental stress at the time of a child's transition to primary school. The findings from this study provide empirical evidence of the effectiveness of the parental training programme and highlight the significance of parenting in promoting a smooth transition for children from kindergarten to primary 1.

Which transition comes first? Urban and demographic transitions in Belgium and Sweden

Directory of Open Access Journals (Sweden)

Philippe Bocquier

2015-12-01

Full Text Available Background: Several theories compete to explain the main drivers of urbanisation, past and present, in relation to both demographic transition and economic development. One hypothesis is that rural-to-urban migration is the driver of urbanisation; another is that urban mortality decline actually triggered urban transition. Objective: This paper reconsiders the relationship between demographic (vital migration and urban transitions by analysing the long-term contribution of natural and migratory movements to urban transition. The respective contributions of birth, death, and migration and their timing will indicate whether economic development, through labour force migration, or vital transition mainly determines urban transition. Methods: After examining the spatial dimension of the demographic transition theory, we use 19th and 20th century series on Sweden and Belgium to better identify the migration component of urban transition through the computation of growth difference between urban and rural areas, accounting for the often neglected reclassification effect. Results: In both Sweden and Belgium, migration is the direct or indirect (through reclassification engine of urban transition and its contribution precedes the onset of vital transition, while the vital transition has a secondary, unstable, and negative role in the urban transition. Conclusions: Changes in the economic sphere are reinstated as the underlying cause of population change, acting through the shift of human capital in space. Methodological consequences are then drawn for analysing vital and urban transitions in an increasingly interdependent world. Contribution: The paper contributes to the theoretical literature on urban and demographic transitions in relation to economic development. The proposed method evaluates migration contribution without having to measure it.

Transitions are societal transformation processes that occur in at least one generation (i.e. 25 years). Transitions are structural changes of the society or a complex part of that society. Transitions show technological, economical, ecological, socio-cultural and institutional developments on different levels. A transition is the result of slow changes (developments in supplies) and fast dynamics (flows). In general, four transition phases can be distinguished: (1) a pre-development phase of dynamic equilibrium in which the status quo does not change much; (2) a take-off phase in which the process of change is started; (3) an acceleration phase in which structural changes occur, resulting in collective learning processes, diffusion and processes of implementation; (4) a stabilization phase in which the speed of societal changes decreases and a new dynamic equilibrium exists. Within the framework of the preparatory process of the Fourth Dutch National Environmental Plan (NMP4) a study has been carried out to explore the transition concept, focusing on an emission-low energy supply in the Netherlands. 49 refs

Certification of adaptive control technologies for both manned and unmanned aircraft represent a major challenge for current Verification and Validation techniques. A (missing) key step towards flight certification of adaptive flight control systems is the definition and development of analysis tools and methods to support Verification and Validation for nonlinear systems, similar to the procedures currently used for linear systems. In this paper, we describe and demonstrate the advantages of L(sub l) adaptive control architectures for closing some of the gaps in certification of adaptive flight control systems, which may facilitate the transition of adaptive control into military and commercial aerospace applications. As illustrative examples, we present the results of a piloted simulation evaluation on the NASA AirSTAR flight test vehicle, and results of an extensive flight test program conducted by the Naval Postgraduate School to demonstrate the advantages of L(sub l) adaptive control as a verifiable robust adaptive flight control system.

Application of quality function deployment in defense technology development

Science.gov (United States)

Cornejo, Estrella De Maria Forster

1998-12-01

Introduction. As advances in aviation technology take place, the research community recognizes, and the operator demands that the progress in technology be integrated with the human component of the same, the aircrew. Integrative programs are primarily concerned with three sub-systems: the operator, the aircraft, and the cockpit. To accomplish their integration, a "dialogue" between the various disciplines addressing these aspects of the weapon system is indispensable. Such dialogue is theorized to be possible via Quality Function Deployment (QFD). QFD emphasizes an understanding of the relationships between the requirements of the aircrew and the technology the research and engineering community provides. In establishing these relationships, program management concerns such as need, applicability, affordability, and transition of the technology are addressed. Procedures. QFD was incorporated in a Performance Methodology (PMM). This methodology associates a particular technology's Measures of Performance (MOP) and the overall weapon system's Measures of Effectiveness (MOE) to which it is applied. Incorporation of QFD in the PMM was hypothesized to result in an improved PMM (Q-PMM) that would address both, the aircrew's interests and those of program management. Both methodologies were performed. The g-ensemble was selected as the technology of interest. The Standard and Combat Edge designs were examined for comparison purposes. Technology MOPs were ranked in order of importance in accordance to both the PMM and its proposed improvement, the Q-PMM. These methodologies were then evaluated by way of an experiment in the human centrifuge. This experiment was to answer two questions: Is there a relationship between the technology's MOP and the aircraft's MOEs? Given a MOP-MOE relationship, is there a difference between the two ensembles? Findings. The Q-PMM was superior to the PMM in addressing customer's requirements. The Q-PMM was superior to the PMM in addressing

The flow-pattern transition has been a challenging problem in two-phase flow system. We propose the terahertz time-domain spectroscopy (THz-TDS) to investigate the behavior underlying oil-water flow in rectangular horizontal pipes. The low water content (0.03-2.3%) in oil-water flow can be measured accurately and reliably from the relationship between THz peak amplitude and water volume fraction. In addition, we obtain the flow pattern transition boundaries in terms of flow rates. The critical flow rate Qc of the flow pattern transitions decreases from 0.32 m3 h to 0.18 m3 h when the corresponding water content increases from 0.03% to 2.3%. These properties render THz-TDS particularly powerful technology for investigating a horizontal oil-water two-phase flow system.

Bioenergy transition in rural China: Policy options and co-benefits

International Nuclear Information System (INIS)

Gan Lin; Yu Juan

2008-01-01

This paper reviews the current situation of bioenergy development in China, particularly on its relationship to sustainable rural development. It argues that the current government strategy, investment policy and industrial interest are over-emphasized on biomass-burning power generation as part of the clean energy development trajectories, which may not lead to the most cost-effective outcomes in terms of investments, resource use and social development objectives. It points out that there are large potentials in developing and disseminating household-based biomass technologies in rural areas, especially with energy-efficient modern biomass stoves, which can produce far more economic, social and environmental benefits than biomass power plants. It is a decentralized solution to use renewable energy resources for meeting multi-objectives. It is suggested that key incentive policies be provided by the government to encourage this technological transition, or the leapfrogging from using traditional household stoves towards modern biomass stoves, which will lead to a win-win situation in global, regional and local environmental protection, sustainable resource management and related social benefits, particularly for the poor in remote communities. Six policy recommendations are made: (1) financial schemes development; (2) preferable tax and carbon tax; (3) regulatory policy reform; (4) service industry support; (5) market research, training and capacity building for key stakeholders; (6) development of methodologies and standards for CDM projects. The potential co-benefits brought up by this massive biomass technology transition will bring new perspectives to realizing Millennium Development Goals (MDGs) and global CO 2 emissions reduction targets in China, and also set an example to other developing countries

The phase transition in SO(3) lattice gauge theory is investigated by Monte Carlo techniques with a view (i) to understand the relationship between the bulk transition and the deconfinement transition, and (ii) to resolve the current ambiguity about the nature of the high temperature phase. By introduction of a magnetic field, it was shown that the +ve and -ve values of a > correspond to the same phase. Studies on different sized lattices lead to the conclusion that in SO(3), there is only one transition, which is deconfining in nature. (author)

Gulf Arab women's transition to motherhood.

Science.gov (United States)

Missal, Bernita

2013-01-01

This paper is a report of the findings of a study of Gulf Arab women's perspectives of the transition to motherhood. Transition to motherhood is a universal phenomenon in which every culture has its own expectations and varying supports for women moving through this transition. International studies have provided models or categories of maternal responses related to cultural aspects of transition to motherhood. However, no known research has focused on transition to motherhood among Gulf Arab women. In the initial cohort seventeen first time Gulf Arab mothers in the United Arab Emirates were interviewed during the following three times: before childbirth, two-four weeks after childbirth, and forty-days after childbirth. A second cohort of seventeen first time new mothers was interviewed after childbirth in Sultanate of Oman. Four patterns were identified as indicators of change as women transitioned into motherhood: 1) Women's personal transition: women changed from feeling of freedom to feeling of dependency to self-confidence. 2) Mother/baby relationships: women changed from fear, anxiety, and uncertainty to feelings of care and confidence. 3) Family influences: women experienced family support to being integrated and feeling respected by family. 4) Cultural/religious beliefs and practices: women felt they were initially observers of culture, to experiencing cultural/religious beliefs and practices. This was followed by accomplishment in childbearing and childrearing practices. As Gulf Arab new mothers made the transition to motherhood, four implications for international nursing practice emerged: 1) patient teaching to help relieve anxiety, fears, and uncertainty, 2) facilitation of mother/baby relationships, 3) family-centered care, and 4) the importance of cultural/religious beliefs and practices to new mothers.

Full Text Available Small and medium enterprises (SMEs are playing an increasingly important role in sustaining geo strategies and global peace economic growth and logistic system in Malaysia. SMEs also play a very crucial role in customer relationship as they may serve the roles of customer, distributor producer and supplier. However, adaption of customer relationship in Malaysian SMEs has not been fully explored. CRMP model for logistic service presents the combination of technology strategy in term of geo strategies and global peace. The goal of this study is to investigate customer relationship management performance and technology strategy. The dimensions for technology factors are Support information system, information sharing, Usefulness, care/help, ease of use, service portfolio, security and Update System. The populations of study were customers from a logistic company located in Pulau Pinang. Simple random sampling was selected from the target populations. Data collection resulted in 100 respondents to answers questionnaire from the customers of logistic company. Based on the finding, the result showed that, technology strategies are anchor factors in determining geo strategies and global peace on customer relationship management performance. Further study has important managerial implications as the findings will enable management of SMEs to understand progressive and highly varied CRMP practices and contextual factors that contribute to the CRMP as well as geo strategies and global peace and innovative implementation.

Noland, Robert B; Weiner, Marc D; Klein, Nicholas J; Puniello, Orin D

2017-04-01

We evaluated a training course called "Orientation to Transit Procurement", designed and conducted by the National Transit Institute. This course is designed to provide Federal Transit Administration (FTA) grantees an overview of regulations and best practices related to the procurement process. Our objective in conducting the evaluation was to understand how transit agency staff made changes in procurement practices in response to the course training. The evaluation was mixed mode: an Internet survey followed by in-depth interviews with a small group of respondents. Survey respondents were also provided with an open-ended question providing us with additional context for our evaluation. Results show that the training is substantially successful at meeting the goal of improving procurement practices at transit agencies; indeed, most respondents report making changes at their agencies as the proximate result of the training. This was at odds with our exploration of knowledge of procurement topics, as most respondents gave inaccurate answers on multiple-choice "knowledge questions". This may have been due to question structure or, more likely, the nature of online surveys. Suitable training on the procurement of information technology was also a main concern. The lack of training in this area is indicative of the broader challenge facing public transit agencies in how to incorporate new forms of technology into their existing practices and bureaucratic structures.

Evolutionary modelling of transitions to sustainable development

International Nuclear Information System (INIS)

Safarzynska, K.

2010-01-01

This thesis has examined how evolutionary economics can contribute to modelling the micromechanisms that underlie transitions towards sustainable development. In general, transitions are fundamental or structural system changes. They involve, or even require, escaping lock-in of dominant, environmentally unsustainable technologies, introducing major technical or social innovations, and changing prevailing social practices and structures. Due to the complexity of socioeconomic interactions, it is not always possible to identify, and thus target with appropriate policy instruments, causes of specific unsustainable patterns of behaviour. Formal modelling exercises can help improve our understanding of the interaction of various transition mechanisms which are otherwise difficult to grasp intuitively. They allow exploring effects of policy interventions in complex systems. However, existing models of transitions focus on social phenomena and seldom address economic problems. As opposed, mainstream (neoclassical) economic models of technological change do not account for social interactions, and changing heterogeneity of users and their perspectives - even though all of these can influence the direction of innovations and patterns of socio-technological development. Evolutionary economics offers an approach that goes beyond neoclassical economics - in the sense of employing more realistic assumptions regarding the behaviour and heterogeneity of consumers, firms and investors. It can complement current transition models by providing them with a better understanding of associated economic dynamics. In this thesis, formal models were proposed to illustrate the usefulness of a range of evolutionary-economic techniques for modelling transitions. Modelling exercises aimed to explain the core properties of socio-economic systems, such as lock-in, path-dependence, coevolution, group selection and recombinant innovation. The studies collected in this dissertation illustrate that

A survey of soft modes and their relationship to structural phase transitions is presented. After introducing the concept of a soft mode, the origin of softening is considered from a lattice-dynamical point. The Landau theory approach to structural transitions is then discussed, followed by a generalisation of the soft-mode concept through the use of the dynamic order-parameter susceptibility. The relationship of soft modes to broken symmetry is also examined. Experimental results for several classes of crystals are next presented, bringing out various features such as the co-operative Jahn-Teller effect. The survey concludes with a discussion of the central peak, touching upon both the experimental results and the theoretical speculations.

The main objective of this experiment was to monitor the rumination pattern during the transition period in primiparous (PR) and pluriparous (PL) dairy cows and to investigate its relationships with metabolic conditions, milk yield, and health status. The study was carried out in an experimental free-stall barn and involved 32 Italian Friesian cows (9 PR and 23 PL) during the transition phase. The rumination time (RT) was recorded with an automatic system (HR-Tag), and data were calculated and summarized in 2-h intervals. Blood samples were collected during the transition phase to assess biochemical variables related to energy, protein, and mineral metabolism, as well as markers of inflammatory conditions and some enzyme activity. Daily milk yield, BW, nutritional condition, and health status were also recorded. The average RT before calving (-20 to -6 d) was 463 min/d in PR (range 270 to 620) and 522 min/d in PL (range 411 to 640). In the early lactation [15 to 40 d in milk (DIM)], the average RT was 504 min/d in PR (range 400 to 585) and 562 min/d in PL (range 414 to 685) and was positively correlated with milk yield (r = 0.36; P Cows with reduced RT before calving maintained reduced RT after calving and suffered a greater frequency of disease than cows with greater RT in late pregnancy. Moreover, cows characterized by mild inflammatory conditions and without health disorders or only mild health disorders during the puerperium showed a greater average rumination time (over 520 min/d) during the first 10 d of lactation. Conversely, the decreased RT (450 min/d) during the first few days of lactation was observed in cows with subclinical diseases or health disorders. Cows affected by clinical mastitis during the trial showed a reduction of RT and a change in its variability already some days before the drug treatment. Our results suggest that the automatic measurement of RT is useful to predict calving time and to quickly obtain information on health status of the

First Year Distance Transition Pedagogy: Synchronous online classrooms

2013-04-01

Full Text Available The design and facilitation of distance online courses for first year students must consider both first year, and distance pedagogy. One technology with the promise to meet the needs of first year distance students is the synchronous online classroom. Teacher practice as they transition from face to face to distance environments is influenced by their private theories about technology and pedagogy. Any limitations posed by these private theories may limit in turn the technological, pedagogical and content knowledge of the teachers – TPACK. This paper reports on the case of a regional university as it transitions to online, distance learning in the first year context, with a particular focus on pedagogy in the online classroom. It contributes to the first year pedagogy literature by considering the influences of existing practice of university teachers in the transition to distance learning with a particular focus on synchronous web-based tutorials. It provides recommendations to other institutions in terms of transition strategies, the pedagogical and learning benefits that are enabled and professional development needs of teachers.

Sachiko Ozawa

Full Text Available With declines in development assistance for health and growing interest in country ownership, donors are increasingly faced with the task of transitioning health programs to local actors towards a path to sustainability. Yet there is little available guidance on how to measure and evaluate the success of a transition and its subsequent effects. This study assesses the transition of the Avahan HIV/AIDS prevention program in India to investigate how preparations for transition affected continuation of program activities post-transition.Two rounds of two surveys were conducted and supplemented by data from government and Avahan Computerized Management Information Systems (CMIS. Exploratory factor analysis was used to develop two measures: 1 transition readiness pre-transition, and 2 institutionalization (i.e. integration of initial program systems into organizational procedures and behaviors post-transition. A fixed effects model was built to examine changes in key program delivery outcomes over time. An ordinary least square regression was used to assess the relationship between transition readiness and sustainability of service outcomes both directly, and indirectly through institutionalization.Transition readiness data revealed 3 factors (capacity, alignment and communication, on a 15-item scale with adequate internal consistency (alpha 0.73. Institutionalization was modeled as a unidimensional construct, and a 12-item scale demonstrated moderate internal consistency (alpha 0.60. Coverage of key populations and condom distribution were sustained compared to pre-transition levels (p<0.01. Transition readiness, but not institutionalization, predicted sustained outcomes post-transition. Transition readiness did not necessarily lead to institutionalization of key program elements one year after transition.Greater preparedness prior to transition is important to achieve better service delivery outcomes post-transition.

The Heterogeneity of Job Creation and Destruction in Transition and Non-transition Developing Countries: The Effects of Firm Size, Age and Ownership

Directory of Open Access Journals (Sweden)

Haggai Kennedy Ochieng

2017-12-01

Full Text Available This paper investigates how firm age, size and ownership are related with job creation and destruction, and how these patterns differ across transition and non-transition economies. The analysis finds that age is inversely related with gross job creation and net job creation in the two samples. This finding is consistent with the theory of the learning effect. The relationship between age and job destruction is indifferent in non-transition economies. On the contrary, old firms in transition economies destroy more jobs than young ones. The paper further establishes an inverse relationship between size and gross job creation in the two groups. However, there is divergence between the two samples; small firms in non-transition economies also exhibit a higher gross job destruction rate. Consequently large firms have a higher net job creation rate. In transition economies, small and large firms exhibit similar rates of job destruction. But small firms retain a higher net job creation rate. A more intriguing finding is that state owned firms do not underperform domestic private ones. This means these countries may be using soft budget constraint which allows state owned firms to overstaff. Finally, crowding out of SMEs by foreign owned firms is not evident in transition economies.

Slocombe, Daniel R; Kuznetsov, Vladimir L; Grochala, Wojciech; Williams, Robert J P; Edwards, Peter P

2015-03-13

A qualitative account of the occurrence and magnitude of superconductivity in the transition metals is presented, with a primary emphasis on elements of the first row. Correlations of the important parameters of the Bardeen-Cooper-Schrieffer theory of superconductivity are highlighted with respect to the number of d-shell electrons per atom of the transition elements. The relation between the systematics of superconductivity in the transition metals and the periodic table high-lights the importance of short-range or chemical bonding on the remarkable natural phenomenon of superconductivity in the chemical elements. A relationship between superconductivity and lattice instability appears naturally as a balance and competition between localized covalent bonding and so-called broken covalency, which favours d-electron delocalization and superconductivity. In this manner, the systematics of superconductivity and various other physical properties of the transition elements are related and unified. © 2015 The Author(s) Published by the Royal Society.

The transition to parenthood can be a challenging time, in which both mothers and fathers experience increased risk of distress and depression. Mothers are more likely than fathers to engage with services and have their mental health monitored and attended to during the perinatal period. The present study aimed to explore whether smartphone technology could be used to address fathers' needs across their transition to fatherhood. A corpus of messages, including linked information and mood tracking software, was designed to support and enhance paternal relationships with their babies, their partners and themselves across the perinatal period. Messages were sent to project participants (N = 520) from 12-weeks' gestation to 24-weeks after birth. Of those fathers enrolled (N = 520), 21.5% scored >13 on K6 and completion rate (85%) was similar between these and other fathers. Most fathers (63.1%) clicked at least one link and responses were received for 20.5% of mood tracker questions. The probability of reporting worse mood scores decreased over time. Fathers completing post study surveys (N = 101) reported that messages helped them in their experience of becoming a new dad (92.8%), as well as helping them develop a strong relationship with their new child (54.9%), and in their relationship with their partner (79%). The present study has demonstrated that it is both feasible and acceptable to support new fathers with SMS4dads, a relationship-focused messaging system designed to be delivered to smartphones across fathers' transition to parenthood.

Spatial Variation of Regional Sustainable Development and its Relationship to the Allocation of Science and Technology Resources

2014-09-01

Full Text Available With the increasing of labor salaries, the RMB exchange rate, resource product prices and requirements of environmental protection, inexpensive labor and land are no longer the decisive factor of regional competitiveness. From this perspective, China needs to shift from the extensive development mode to the sustainable development mode. Science and technology resources rational allocation is one of the key issues in sustainable development. Based on the counties (districts data of Zhejiang Province in China, this paper portrays the spatial variation of regional sustainable development level of this area. This paper finds that counties tend to cluster in groups with the same sustainable development level, and this agglomeration trend has been enforced during the past several years. It then testifies to the relationship between the allocation of science and technology resources and local sustainable development, identifies science and technology human resources, financial resources and environmental resource are positively related to local sustainable development, except government financial support. The economic level has a negative relationship with regional sustainable development. This is because the development of the Zhejiang economy grown at the expense of the environment and ecosystem. Some advice is given according to the empirical analysis result.

Transitioning Unmanned Technologies for Earth Science Applications

Science.gov (United States)

Wardell, L. J.; Douglas, J.

2008-12-01

Development of small unmanned aerial systems (UAS) has progressed dramatically in recent years along with miniaturization of sensor technology. This confluence of development paths has resulted in greater capability in smaller, less expensive platforms allowing research to be performed where manned airborne platforms are impractical or dangerous. Recent applications include small UAS for studies involving hurricanes, volcanic activity, sea ice changes, glacier melt, biological monitoring of land and sea species, wildfire monitoring, and others. However, the majority of UAS employed in these investigations were originally developed for non-civilian applications and many of the required interfaces are locked behind proprietary specifications, requiring expensive customization by the manufacturer to transform a military UAS into one suitable for civilian work. A small UAS for scientific research should be standards-based, low-cost, user friendly, field serviceable, and be designed to accept a range of payloads. The AV8R UAS is one example of an unmanned system that has been developed for specific application to earth observation missions. This system is designed to be operated by the user with difficult environmental conditions and field logistics in mind. Numerous features and innovations that advance this technology as a research tool as well as its planned science missions will be presented. Most importantly, all interfaces to the system required for successful design and integration of various payloads will be openly available. The environment of open, standards based development allow the small technologies companies that serve as the backbone for much of the technology development to participate in the rapid development of industry capabilities. This is particularly true with UAS technologies. Programs within the USA such as the STTR foster collaborations with small businesses and university researchers.

Alginate pellets prepared by the aqueous agglomeration technique experience fast drug dissolution due to the porous pre-formed calcium alginate microstructure. This study investigated in vitro drug release, preclinical and clinical pharmacokinetics relationships of intestinal-specific calcium acetate-alginate pellets against calcium-free and calcium carbonate-alginate pellets. Alginate pellets were prepared by solvent-free melt pelletization instead of aqueous agglomeration technique using chlorpheniramine maleate as model drug. A fast in situ calcium acetate dissolution in pellets resulted in rapid pellet breakup, soluble Ca(2+) crosslinking of alginate fragments and drug dissolution retardation at pH 1.2, which were not found in other pellet types. The preclinical drug absorption rate was lower with calcium acetate loaded than calcium-free alginate pellets. In human subjects, however, the extent and the rate of drug absorption were higher from calcium acetate-loaded pellets than calcium-free alginate pellets. The fine, dispersible and weakly gastric mucoadhesive calcium alginate pellets underwent fast human gastrointestinal transit. They released the drug at a greater rate than calcium-free pellets in the intestine, thereby promoting drug bioavailability. Calcium acetate was required as a disintegrant more than as a crosslinking agent clinically to promote pellet fragmentation, fast gastrointestinal transit and drug release in intestinal medium, and intestinal-specific drug bioavailability.

Transition without Conflict? Renewable Energy Initiatives in the Dutch Energy Transition

Directory of Open Access Journals (Sweden)

Antonia Proka

2018-05-01

Full Text Available In the context of the slowly progressing energy transition, a number of renewable energy initiatives have been emerging in the Netherlands. These initiatives represent alternatives to the dominant functioning of the energy system, and as such, may come into conflict with it. Transitions involve system destabilisation and conflict between the incumbent regime and the initiatives originating in niches. In order to assess the transformative potential of such initiatives, this paper addresses the question: what kind of conflicts and tensions arise from renewable energy initiatives, and what strategies do they develop to overcome or avoid them? Combined with a business model perspective, transition thinking enabled a better understanding of how the initiatives organise themselves, and where the points of friction with their institutional context emerge. We suggest that the instances of conflict may function as an indication for the state of the energy transition and the transformative potential impact of such initiatives. The instances discussed in this contribution relate to existing support schemes, technology choices, and the overall organisational networks of the emerging sector.

Relationship behaviors contribute to compromised health or resilience. Everyday communication between intimate partners represents the vast majority of their interactions. When intimate partners take on new roles as patients and caregivers, everyday communication takes on a new and important role in managing both the transition and the adaptation to the change in health status. However, everyday communication and its relation to health has been little studied, likely due to barriers in collecting and processing this kind of data. The goal of this paper is to describe deterrents to capturing naturalistic, day-in-the-life communication data and share how technological advances have helped surmount them. We provide examples from a current study and describe how we anticipate technology will further change research capabilities. Copyright © 2017 Elsevier B.V. All rights reserved.

The relationship between telehealth and information technology ranges from that of uneasy bedfellows to creative partnerships.

Science.gov (United States)

Wade, Victoria A; Hamlyn, Jeremy S

2013-10-01

The relationship between the clinical and technical aspects of a telehealth operation is frequently problematic, and technically-driven projects often fail to achieve sustainability. Qualitative data from a study of 37 Australian telehealth services were analysed to understand how the relationship between telehealth providers and information technology (IT) departments helps or hinders the development of telehealth. The most frequent difficulties reported were between telehealth services and the internal IT departments of health services, rather than with external vendors. The difficulties included barriers to installing telehealth over IT networks, a lack of priority given to telehealth services, and IT departments insisting on standardised approach. Alternatively, when IT staff were assigned to supporting clinical staff and had a close working relationship with them, they were major enablers of telehealth services. Authorising dedicated IT support and encouraging joint problem solving should provide a strong foundation for a healthy relationship which contributes to the growth and sustainability of telehealth.

van Scheppingen, Manon A; Denissen, Jaap J A; Chung, Joanne M; Tambs, Kristian; Bleidorn, Wiebke

2018-06-01

In the current study, we used 5 waves of longitudinal data from a large representative sample of Norwegian mothers (N = 84,711) to examine the association between romantic relationship satisfaction and self-esteem before and after childbirth in subgroups of first-, second-, third-, and fourth-time mothers. Maternal self-esteem showed a highly similar change pattern across subgroups. Specifically, self-esteem decreased during pregnancy, increased until the child was 6 months old, and then gradually decreased over the following years. The replication of this trajectory across subgroups and pregnancies suggests that this is a normative change pattern. For relationship satisfaction, the birth of the first child seemed to have the strongest impact compared with the birth of subsequent children. In first-time mothers, relationship satisfaction was high during pregnancy, sharply decreased around childbirth, and then gradually decreased in the following years. In second-, third-, and fourth-time mothers, the decrease in relationship satisfaction after childbirth was more gradual and linear compared with the sharp decrease found in first-time mothers. Moderate positive correlated changes between self-esteem and relationship satisfaction indicated that these constructs were linked over time. Discussion focuses on the implications of the results for theory and future research on self-esteem, relationship satisfaction, and personality-relationship transactions.

Bridging Differences -- how Social Relationships and Racial Diversity Matter in a Girls' Technology Program

Science.gov (United States)

Kekelis, Linda S.; Ancheta, Rebecca Wepsic; Heber, Etta; Countryman, Jeri

In this article, we explore an understudied dimension of girls' single-sex education - how social relationships and racial diversity impact the educational environment for girls, and how teachers may best address these concerns. Findings are presented from a 3-year qualitative study of girls' experiences in a single-sex technology program. Girls valued the all-girls aspect of the programs, and friendships formed the foundation of their social experiences. Girls' friendship groups influenced their experiences and eventually their success in the after school technology programs. When friendship groups were observed to be racially homogeneous, they created challenges for including and supporting a racially diverse student membership. Our responses to the challenges that cultural differences and tensions present are outlined, along with recommendations for helping girls bridge these differences.

In 87 randomly selected diabetic patients (67 type 1, 20 type 2) and 25 control subjects, gastric emptying of digestible solid and liquid meals and oesophageal transit of a solid bolus were measured with scintigraphic techniques. Gastrointestinal symptoms, autonomic nerve function and glycaemic control were evaluated in the diabetic patients. Gastric emptying and oesophageal transit were slower (P 15 mmol/l. These results indicate that gastric emptying in patients with diabetes mellitus should be assessed by liquid as well as by solid test meals and that oesophageal transit should not be used as a predictor of generalised diabetic gastroenteropathy.

FOOD PROCESSING TECHNOLOGY AS A MEDIATOR OF FUNCTIONALITY. STRUCTURE-PROPERTY-PROCESS RELATIONSHIPS

Directory of Open Access Journals (Sweden)

Ester Betoret

2015-02-01

Full Text Available During the last years, the food industry has been facing technical and economic changes both in society and in the food processing practices, paying high attention to food products that meet the consumers´ demands. In this direction, the study areas in food process and products have evolved mainly from safety to other topics such as quality, environment or health. The improvement of the food products is now directed towards ensuring nutritional and specific functional benefits. Regarding the processes evolution, they are directed to ensure the quality and safety of environmentally friendly food products produced optimizing the use of resources, minimally affecting or even enhancing their nutritional and beneficial characteristics. The product structure both in its raw form and after processing plays an important role maintaining, enhancing and delivering the bioactive compounds in the appropriate target within the organism. The aim of this review is to make an overview on some synergistic technologies that can constitute a technological process to develop functional foods, enhancing the technological and/or nutritional functionality of the food products in which they are applied. More concretely, the effect of homogenization, vacuum impregnation and drying operations on bioactive compounds have been reviewed, focusing on the structure changes produced and its relationship on the product functionality, as well as on the parameters and the strategies used to quantify and increase the achieved functionality.

Taboada, María; Martínez, Diego; Pilo, Belén; Jiménez-Escrig, Adriano; Robinson, Peter N; Sobrido, María J

2012-07-31

Semantic Web technology can considerably catalyze translational genetics and genomics research in medicine, where the interchange of information between basic research and clinical levels becomes crucial. This exchange involves mapping abstract phenotype descriptions from research resources, such as knowledge databases and catalogs, to unstructured datasets produced through experimental methods and clinical practice. This is especially true for the construction of mutation databases. This paper presents a way of harmonizing abstract phenotype descriptions with patient data from clinical practice, and querying this dataset about relationships between phenotypes and genetic variants, at different levels of abstraction. Due to the current availability of ontological and terminological resources that have already reached some consensus in biomedicine, a reuse-based ontology engineering approach was followed. The proposed approach uses the Ontology Web Language (OWL) to represent the phenotype ontology and the patient model, the Semantic Web Rule Language (SWRL) to bridge the gap between phenotype descriptions and clinical data, and the Semantic Query Web Rule Language (SQWRL) to query relevant phenotype-genotype bidirectional relationships. The work tests the use of semantic web technology in the biomedical research domain named cerebrotendinous xanthomatosis (CTX), using a real dataset and ontologies. A framework to query relevant phenotype-genotype bidirectional relationships is provided. Phenotype descriptions and patient data were harmonized by defining 28 Horn-like rules in terms of the OWL concepts. In total, 24 patterns of SWQRL queries were designed following the initial list of competency questions. As the approach is based on OWL, the semantic of the framework adapts the standard logical model of an open world assumption. This work demonstrates how semantic web technologies can be used to support flexible representation and computational inference mechanisms

Scaling Relationships for Adsorption Energies of C2 Hydrocarbons on Transition Metal Surfaces

Energy Technology Data Exchange (ETDEWEB)

Jones, G

2011-08-18

Using density functional theory calculations we show that the adsorption energies for C{sub 2}H{sub x}-type adsorbates on transition metal surfaces scale with each other according to a simple bond order conservation model. This observation generalizes some recently recognized adsorption energy scaling laws for AH{sub x}-type adsorbates to unsaturated hydrocarbons and establishes a coherent simplified description of saturated as well as unsaturated hydrocarbons adsorbed on transition metal surfaces. A number of potential applications are discussed. We apply the model to the dehydrogenation of ethane over pure transition metal catalysts. Comparison with the corresponding full density functional theory calculations shows excellent agreement.

Enabling online studies of conceptual relationships between medical terms: developing an efficient web platform.

2014-10-07

The Unified Medical Language System (UMLS) contains many important ontologies in which terms are connected by semantic relations. For many studies on the relationships between biomedical concepts, the use of transitively associated information from ontologies and the UMLS has been shown to be effective. Although there are a few tools and methods available for extracting transitive relationships from the UMLS, they usually have major restrictions on the length of transitive relations or on the number of data sources. Our goal was to design an efficient online platform that enables efficient studies on the conceptual relationships between any medical terms. To overcome the restrictions of available methods and to facilitate studies on the conceptual relationships between medical terms, we developed a Web platform, onGrid, that supports efficient transitive queries and conceptual relationship studies using the UMLS. This framework uses the latest technique in converting natural language queries into UMLS concepts, performs efficient transitive queries, and visualizes the result paths. It also dynamically builds a relationship matrix for two sets of input biomedical terms. We are thus able to perform effective studies on conceptual relationships between medical terms based on their relationship matrix. The advantage of onGrid is that it can be applied to study any two sets of biomedical concept relations and the relations within one set of biomedical concepts. We use onGrid to study the disease-disease relationships in the Online Mendelian Inheritance in Man (OMIM). By crossvalidating our results with an external database, the Comparative Toxicogenomics Database (CTD), we demonstrated that onGrid is effective for the study of conceptual relationships between medical terms. onGrid is an efficient tool for querying the UMLS for transitive relations, studying the relationship between medical terms, and generating hypotheses.

Directory of Open Access Journals (Sweden)

Ranković Marko

2012-06-01

Full Text Available This paper is dealing with treats of inflation in times of world financial turmoil. It examines how inflation is impacting macroeconomic factors. Is there relationship and how strong it is between inflation and economic growth, unemployment rate and other selected economic indicators? Motivated by these questions, this paper examines the relationship between inflation and selected macroeconomic indicators: real GDP annual growth rate, privatization revenues, as part of the GDP, level of investments, unemployment rate and share of assets of foreign banks in domestic bank system by using data for 13 transition economies over the period 1993-2008. The evidence strongly supports the view that the relationship between inflation and selected macroeconomic indicators is significantly and strongly negative, observed for the region. However, for small number countries in transition there is no direct significant relationship between inflation, but indirect relationship has been showed.

Science.gov (United States)

Shanske, Susan; Arnold, Janis; Carvalho, Maria; Rein, Jennifer

2012-01-01

Transition from pediatric to adult medical care and the significant psychosocial considerations impacting this developmental process are a primary focus in health care today. Social workers are often the informal brokers of this complex and nuanced process and are uniquely trained to complete biopsychosocial assessments to understand the needs of patients and families and address psychosocial factors. Their extensive knowledge of resources and systems, along with their sophisticated understanding of the relationship issues, family dynamics, cultural implications, and basic person-in-context approach allow for unique collaboration with the health care team, family, and community supports to develop successful transition plans and programs.

Computational advances in transition phase analysis

Morita, K.; Kondo, S.; Tobita, Y.; Shirakawa, N.; Brear, D.J.; Fischer, E.A.

1994-01-01

In this paper, historical perspective and recent advances are reviewed on computational technologies to evaluate a transition phase of core disruptive accidents in liquid-metal fast reactors. An analysis of the transition phase requires treatment of multi-phase multi-component thermohydraulics coupled with space- and energy-dependent neutron kinetics. Such a comprehensive modeling effort was initiated when the program of SIMMER-series computer code development was initiated in the late 1970s in the USA. Successful application of the latest SIMMER-II in USA, western Europe and Japan have proved its effectiveness, but, at the same time, several areas that require further research have been identified. Based on the experience and lessons learned during the SIMMER-II application through 1980s, a new project of SIMMER-III development is underway at the Power Reactor and Nuclear Fuel Development Corporation (PNC), Japan. The models and methods of SIMMER-III are briefly described with emphasis on recent advances in multi-phase multi-component fluid dynamics technologies and their expected implication on a future reliable transition phase analysis.

Kato, H.; Chen, H.-S.; Inoue, A.

2008-01-01

The thermal expansion coefficients of 13 metallic glasses were measured using a thermo-mechanical analyser. A unique correlation was found between the linear thermal expansion coefficient and the glass transition temperature-their product is nearly constant ∼8.24 x 10 -3 . If one assumes the Debye expression for thermal activation, the total linear thermal expansion up to glass transition temperature (T g ) is reduced to 6 x 10 -3 , nearly 25% of that at the fusion of pure metals

A large variety of complex systems in ecology, climate science, biomedicine and engineering have been observed to exhibit tipping points, where the dynamical state of the system abruptly changes. For example, such critical transitions may result in the sudden change of ecological environments...... a priori known events are preceded by variance and autocorrelation growth. Our findings thus clearly establish the necessary starting point to further investigate the relationship between abstract mathematical theory and various classes of critical transitions in social networks....

Spatial heterogeneity in liquid–liquid phase transition

2017-01-01

Molecular dynamics simulations are performed to investigate the liquid–liquid phase transition (LLPT) and the spatial heterogeneity in Al–Pb monotectic alloys. The results reveal that homogeneous liquid Al–Pb alloy undergoes an LLPT, separating into Al-rich and Pb-rich domains, which is quite different from the isocompositional liquid water with a transition between low-density liquid (LDL) and high-density liquid (HDL). With spatial heterogeneity becoming large, LLPT takes place correspondingly. The relationship between the cooling rate, relaxation temperature and percentage of Al and the spatial heterogeneity is also reported. This study may throw light on the relationship between the structure heterogeneity and LLPT, which provides novel strategies to control the microstructures in the fabrication of the material with high performance.

Three routes forward for biofuels: Incremental, leapfrog, and transitional

International Nuclear Information System (INIS)

Morrison, Geoff M.; Witcover, Julie; Parker, Nathan C.; Fulton, Lew

2016-01-01

This paper examines three technology routes for lowering the carbon intensity of biofuels: (1) a leapfrog route that focuses on major technological breakthroughs in lignocellulosic pathways at new, stand-alone biorefineries; (2) an incremental route in which improvements are made to existing U.S. corn ethanol and soybean biodiesel biorefineries; and (3) a transitional route in which biotechnology firms gain experience growing, handling, or chemically converting lignocellulosic biomass in a lower-risk fashion than leapfrog biorefineries by leveraging existing capital stock. We find the incremental route is likely to involve the largest production volumes and greenhouse gas benefits until at least the mid-2020s, but transitional and leapfrog biofuels together have far greater long-term potential. We estimate that the Renewable Fuel Standard, California's Low Carbon Fuel Standard, and federal tax credits provided an incentive of roughly $1.5–2.5 per gallon of leapfrog biofuel between 2012 and 2015, but that regulatory elements in these policies mostly incentivize lower-risk incremental investments. Adjustments in policy may be necessary to bring a greater focus on transitional technologies that provide targeted learning and cost reduction opportunities for leapfrog biofuels. - Highlights: • Three technological pathways are compared that lower carbon intensity of biofuels. • Incremental changes lead to faster greenhouse gas reductions. • Leapfrog changes lead to greatest long-term potential. • Two main biofuel policies (RFS and LCFS) are largely incremental in nature. • Transitional biofuels offer medium-risk, medium reward pathway.

2015-07-01

Full Text Available Customer relationship management, as a process to manage customer relationship initiation, maintenance and termination to maximize the value of the relationship portfolio, is an evolving process. In recent years, the development of interactive technologies (social media have revolutionized the interaction between firms and their customers and between customers. The impact of technology on CRM is improving ways of collecting and processing customer information and transforming communication with customers. In the context of the development of social networks, the introduction of social media applications in customer relationship management activities bring important changes in this area. Thus, managers need to pay attention to the interaction management as an important process of CRM and enhance the customer relationship management capabilities. The study propose a conceptual research model of several antecedents of customer relationship managements capabilities and provide the linkage between this antecedents and CRM capabilities. First, following review of existing research literature related to customer relationship management, there are some conceptual clarification on customer relationship management. Second, are presented the working concepts: the adoption of interactive technologies, customer concept, customer empowerment, customer relationship orientation and customer-centric management system. Then, it is proposed the conceptual model and finally are presented conclusions, managerial implications, limitations and research directions. From a theoretical perspective, this paper highlights the importance of marketing actions at the individual customer level and reveal the impact of adoption by companies of interactive technologies so that organizations have the opportunity to engage in conversations with customers and respond in real time the requirements that they launched the online environment. Nowadays, customers feel empowered and play

Phase transitions and dark matter problems

International Nuclear Information System (INIS)

Schramm, D.N.

1984-10-01

The possible relationships between phase transitions in the early universe and dark matter problems are discussed. It is shown that there are at least 3 distinct cosmological dark matter problems: (1) halos; (2) galaxy formation and clustering; and (3) Ω = 1, each emphasizing different attributes for the dark matter. At least some of the dark matter must be baryonic but if problems 2 and 3 are real they seem to also require non-baryonic material. However, if seeds are generated at the quark-hardon-chiral symmetry transition then alternatives to the standard scenarios may occur. At present no simple simultaneous solution (neither hot, warm, nor cold) exists for all 3 problems, but non-standard solutions with strings, decaying particles or light not tracing to mass may work. An alternative interpretation of the relationship of the cluster-cluster and galaxy-galaxy correlation functions using renormalized scaling is mentioned. In this interpretation galaxies are more strongly correlated and the cluster-cluster function is not expected to go negative until greater than or equal to 200 Mpc. Possible phase transition origins for the cluster-cluster renormalized scale are presented as ways to obtain a dimension 1.2 fractal. 64 references

Implementing energy transition - A legal deciphering

International Nuclear Information System (INIS)

Bain-Thouverez, Justine; Romi, Raphael; Chautard, Thomas

2016-07-01

As the French law on energy transition reconfigures many parameters of implementation of public action, the authors propose a cross-referenced reading of this law, of the law for new organisation of territories (NOTRe) in its environmental dimension, and of the regulation which results from these legal standards, in order to have a better view on public action in terms of abilities, and of action and financial levers. In a first part, the author discuss the relationships of energy transition with State, regions, districts, EPCI (communal collaboration public body), communes, and public bodies. In the second part, they address the new levers for action, and finally address the financing of energy transition (financing funds, third-party financing companies)

In 1970s, the material patent system was introduced in Japan. Since then, many Japanese pharmaceutical companies have endeavored to create original in-house products. From 1980s, many of the innovative products were small molecular drugs and were developed using powerful medicinal-chemical technologies. Among them were antibiotics and effective remedies for the digestive organs and circulatory organs. During this period, Japanese companies were able to launch some blockbuster drugs. At the same time, the pharmaceutical market, which had grown rapidly for two decades, was beginning to level off. From the late 1990s, drug development was slowing down due to the lack of expertise in biotechnology such as genetic engineering. In response to the circumstances, the research and development on biotechnology-based drugs such as antibody drugs have become more dynamic and popular at companies than small molecule drugs. In this paper, the writers reviewed in detail the transitions in drug discovery and development between 1980 and 2010.

Liu, Pai; Heinson, William R.; Sumlin, Benjamin J.; Shen, Kuan-Yu; Chakrabarty, Rajan K.

2018-04-01

We establish the kinetics of ballistic-to-diffusive (BD) transition observed in two-dimensional random walk using directional statistics. Directional correlation is parameterized using the walker's turning angle distribution, which follows the commonly adopted wrapped Cauchy distribution (WCD) function. During the BD transition, the concentration factor (ρ) governing the WCD shape is observed to decrease from its initial value. We next analytically derive the relationship between effective ρ and time, which essentially quantifies the BD transition rate. The prediction of our kinetic expression agrees well with the empirical datasets obtained from correlated random walk simulation. We further connect our formulation with the conventionally used scaling relationship between the walker's mean-square displacement and time.

Coherent control through near-resonant Raman transitions

2006-01-01

The phase of an electronic wave function is shown to play an important role in coherent control experiments. By using a pulse shaping system with a femtosecond laser, we explore the phase relationships among resonant and off-resonant Raman transitions in Li 2 by measuring the phases of the resulting wave packets, or quantum beats. Specific pixels in a liquid-crystal spatial light modulator are used to isolate the resonant and off-resonant portions of the Raman transitions in Li 2 . The off-resonant Raman transitions have an approximately 90 degree sign phase shift with respect to the resonant Raman transition, and there is an approximately 180 degree sign phase shift between the blue-detuned and the red-detuned off-resonant Raman transitions. Calculations using second-order time-dependent perturbation theory for the electronic transitions agree with the experimental results for the laser pulse intensities used here. Interferences between the off-resonant Raman transitions as a function of detuning are used to demonstrate coherent control of the Raman quantum wave packet

To realize the energy transition in the building sector, three types of obstacles have to be overcome: technology-related, process-related and integration of technology and process. To this end an innovation / implementation program has been set up. The intrinsic driver of the program is the realization of increasingly more ambitious energy concepts in three successive waves, allowing for the different actors to learn from the previous wave, to prepare for the next wave and to scale up these type of projects both in terms of quantity and quality. The establishment process of the program identified a key success factor for the transition process itself: the role of the individual.

Energy Transition in the Nebular City: Connecting Transition Thinking, Metabolism Studies, and Urban Design

Directory of Open Access Journals (Sweden)

Griet Juwet

2018-03-01

Full Text Available Transforming urban infrastructures is an essential part of creating more sustainable urban regions. But rethinking these complex systems requires a better understanding of their spatial dimensions and their relation with urban morphology and spatial structure. This paper addresses that gap by examining different conceptualizations of technical infrastructure and space in science, technology and society studies (STS, transition thinking, urban metabolism studies, and urban political ecology, and draws connections with the spatial perspective of urban planning and design. It illustrates and tests these concepts through the case of energy transition in the Flemish region of Belgium. Transport and supply networks have played a crucial role in facilitating, structuring, and reproducing the region’s characteristic dispersed and energy-intensive urban landscape. Bringing different disciplinary perspectives together, the research broadens the conceptualization of the spatial dimension in transition thinking, and identifies useful concepts and design parameters for urban design to engage with the technical and socio-political complexity of transforming urban infrastructure. It reveals the energy transition as an inherently spatial project, and explores the spatially and socio-politically transformative potential of the transition towards a new energy system.

An Institutional Approach to Understanding Energy Transitions

Science.gov (United States)

Koster, Auriane Magdalena

Energy is a central concern of sustainability because how we produce and consume energy affects society, economy, and the environment. Sustainability scientists are interested in energy transitions away from fossil fuels because they are nonrenewable, increasingly expensive, have adverse health effects, and may be the main driver of climate change. They see an opportunity for developing countries to avoid the negative consequences fossil-fuel-based energy systems, and also to increase resilience, by leap-frogging-over the centralized energy grid systems that dominate the developed world. Energy transitions pose both challenges and opportunities. Obstacles to transitions include 1) an existing, centralized, complex energy-grid system, whose function is invisible to most users, 2) coordination and collective-action problems that are path dependent, and 3) difficulty in scaling up RE technologies. Because energy transitions rely on technological and social innovations, I am interested in how institutional factors can be leveraged to surmount these obstacles. The overarching question that underlies my research is: What constellation of institutional, biophysical, and social factors are essential for an energy transition? My objective is to derive a set of "design principles," that I term institutional drivers, for energy transitions analogous to Ostrom's institutional design principles. My dissertation research will analyze energy transitions using two approaches: applying the Institutional Analysis and Development Framework and a comparative case study analysis comprised of both primary and secondary sources. This dissertation includes: 1) an analysis of the world's energy portfolio; 2) a case study analysis of five countries; 3) a description of the institutional factors likely to promote a transition to renewable-energy use; and 4) an in-depth case study of Thailand's progress in replacing nonrenewable energy sources with renewable energy sources. My research will

This study examines technology use for problem solving in diabetes and its relationship to hemoglobin A1C (A1C). A sample of 112 adolescents with type 1 diabetes completed measures assessing use of technologies for diabetes problem solving, including mobile applications, social technologies, and glucose software. Hierarchical regression was performed to identify the contribution of a new nine-item Technology Use for Problem Solving in Type 1 Diabetes (TUPS) scale to A1C, considering known clinical contributors to A1C. Mean age for the sample was 14.5 (SD 1.7) years, mean A1C was 8.9% (SD 1.8%), 50% were female, and diabetes duration was 5.5 (SD 3.5) years. Cronbach's α reliability for TUPS was 0.78. In regression analyses, variables significantly associated with A1C were the socioeconomic status (β = -0.26, P Problem Solving Questionnaire (β = -0.26, P = 0.01), and TUPS (β = 0.26, P = 0.01). Aside from the Diabetes Self-Care Inventory--Revised, each block added significantly to the model R(2). The final model R(2) was 0.22 for modeling A1C (P problem solving and higher A1C. Adolescents with poorer glycemic control may use technology in a reactive, as opposed to preventive, manner. Better understanding of the nature of technology use for self-management over time is needed to guide the development of technology-mediated problem solving tools for youth with type 1 diabetes.

Implications of parent-child relationships for emerging adults' subjective feelings about adulthood.

Lindell, Anna K; Campione-Barr, Nicole; Killoren, Sarah E

2017-10-01

Little is known about the role of parents in promoting their children's successful transition to adulthood, particularly for college students who may maintain stronger ties to parents than other emerging adults. The present study therefore investigated longitudinal implications of parent-child relationship qualities during emerging adults' first year of college for their feelings about the upcoming transition to adulthood 3 years later, as well as implications of 3 types of parental control (behavioral control, psychological control, helicopter parenting) for these associations. Multilevel models indicated that emerging adults who reported less negativity in their relationships with mothers and fathers felt more like adults 3 years later compared with emerging adults with low-quality relationships, while high levels of psychological control and helicopter parenting had detrimental implications for their vocational identity development and perceived competence regarding their transition to adulthood. However, nuanced interactions between parent-child relationship quality and parental control indicated that behavioral control had positive implications for outcomes if it occurred within the context of high-quality relationships, or when utilized with sons. The present study highlights the complex role that parents may play during college students' transition to adulthood, and future work should continue to examine ways that clinicians can incorporate parents as a potential resource for promoting emerging adults' successful transition to adulthood and the workforce.

This work examines a scientometric model that clarifies and identifies the technology of emergence from initial discovery (via original scientific and conference literature), through critical discoveries(via original scientific, conference literature and patents), transitioning through Technology Readiness Levels (TRLs) and ultimately on to commercial application. The purpose of this study therefore, is to address the relationships among multiple disparate sources of information as a way to explain systematically the emergence of new technologies from innovation on through to commercial application. In one example, we investigate the combinations of four distinct and separate searchable on-line networked sources (i.e., scholarly publications and citation, patents, news archives, and on-line mapping networks) as they are assembled to become one collective network (a data set for analysis of relations). In another example, we investigate the combinations of five distinct sources (i.e., university R&D, industry R&D, product emergence, and two levels of annual market revenue [$1B and $10B]). These established networks and relationship become the basis from which to quickly analyze the temporal flow of activity (searchable events) for multiple example subject domains we investigated.

Coglitore, Diego; Edwardson, Stuart P; Macko, Peter; Patterson, Eann A; Whelan, Maurice

2017-12-01

An optical technique for tracking single particles has been used to evaluate the particle diameter at which diffusion transitions from molecular behaviour described by the fractional Stokes-Einstein relationship to particle behaviour described by the classical Stokes-Einstein relationship. The results confirm a prior prediction from molecular dynamic simulations that there is a particle size at which transition occurs and show it is inversely dependent on concentration and viscosity but independent of particle density. For concentrations in the range 5 × 10 -3 to 5 × 10 -6  mg ml -1 and viscosities from 0.8 to 150 mPa s, the transition was found to occur in the diameter range 150-300 nm.

Although socioemotional competencies have been identified as key components of youths’ positive development, most studies on empathy are cross-sectional, and research on the role of the family has focused almost exclusively on parental socialization. This study examined the developmental course of empathy from age 7 to 14 and the within-person associations between sibling warmth and conflict and youths’ empathy. On three occasions across 2 years, mothers, fathers, and the two eldest siblings from 201 White, working- and middle-class families provided questionnaire data. Multilevel models revealed that, controlling for youths’ pubertal status and parental education, girls’ empathy increased during the transition to adolescence and then leveled off, but boys’ lower levels of empathy remained relatively unchanged. Moreover, controlling for parental responsiveness and marital love, at times when firstborns and second-borns reported more sibling warmth and less sibling conflict than usual, they also reported more empathy than usual. The within-person association between sibling warmth and empathy also became stronger over time. Findings highlight gender differences in empathy development and the unique role of siblings in shaping each other’s socioemotional characteristics during adolescence. PMID:22714744

Relationship of electro-physical properties, thermal phase transition and microstructure of organic semiconducting crystals

Organic crystals of Ph/sub 3/MeP(TCNQ) (Triphenyl-methyl-phosphonium tetracyano quino dimethane) and Et/sub 3/A (TCNQ) (Triethyl ammonium tetracyano quino dimethane) exhibit high tensity resistive effect which make them useful for applications like strain gauges, temperature sensitive resistors, etc. previous investigations of the effect of temperature on the electrical conductivity, thermoelectric power and acoustic emission in the range of 300-360 deg. K show the Ph/sub 3/MeP(TCNQ) crystals dispaly reversible phase transitions at 313 and 317 deg. K during heating the cooling, respectively. Contrary to this the crystals of Et/sub 3/A(TCNQ) and the press tablets of Ph/sub 3/MeP(TCNQ) do not display any such transition. Using Differential Scanning Calorimetry (DSC) in this study, we have confirmed that a reversible thermal transition also takes place at the similar temperature in Ph/sub 3/MeP(TCNQ); the transition is absent in Et/sub 3/A(TCNQ) and in press tablets of Ph/sub 3/MeP(TCNQ). Scanning electron Microscopy (SEM) shows number of structural voids in the single crystals of Ph/sub 3/Mep(TCNQ) which indicates that the phase transition is a volumetric phenomenon; the voids in the crystal may allow the volumetric changes. However, absence of surface defects as observed by SEM in Et/sub 3/A(TCNQ) and in pressed Ph/sub 3/MeP(TCNQ) may hinder the change in the volume of the material due to close packing of molecules. This result in the absence of the phase transitions as ascertained by DSC and other previous electro physical studies. (author)

Energy producers in the 21. century: Digital technology at the service of consumers and the energy transition

International Nuclear Information System (INIS)

Chone, Fabien

2017-01-01

Direct Energie, a major player in France and Belgium, has compelled recognition as a well-balanced operator in the production and supply of electricity and natural gas. Having made innovation one of the major axes of its development, this firm is using digital technology for the energy transition and in response to consumer needs. Direct Energie, a supplier of 'energy 4.0', is seeking to position itself as a leader in 'orchestrating' the consumption of energy by its customers. Given this strong position as the single supplier of energy to its customers, the regulatory framework for data transmission must be reviewed to make it compatible with the 'single contract', which binds a customer to a firm that both supplies and transports energy

Troubling distinctions: a semiotics of the nursing/technology relationship.

Science.gov (United States)

Sandelowski, M

1999-09-01

I consider the discursive practices that have served conceptually and ontologically to trouble the boundaries between nursing and technology: between nurse/human/subject and machine/non-human/object. Nursing and technology have been semiotically related largely by two processes: (a) by the metaphor that depicts nursing as technology and (b) by opposition, or as not like and even in conflict with technology. Less frequently but no less significantly, nursing and technology have been semiotically linked (c) by the metaphor that depicts technology as nursing and (d) by metonymy, or by word or picture juxtapositions of nursing with technology. The troubling distinctions between nursing and technology suggest yet another reason why the construction of difference continues to elude nursing.

The Geography of Solar Photovoltaics (PV and a New Low Carbon Urban Transition Theory

Directory of Open Access Journals (Sweden)

Peter Newton

2013-06-01

Full Text Available This paper examines the early phases of a 21st century energy transition that involves distributed generation technologies employing low or zero carbon emission power sources and their take-up within Australia, with particular reference to the major cities and solar photovoltaics (PV. This transition is occurring in a nation with significant path dependency to overcome in relation to fossil fuel use. Tracking the diffusion of solar PV technology within Australia over the past decade provides a basis for assessing those factors underpinning its exponential growth and its associated geography of diffusion. Positive evidence that there are pathways for cities to decarbonise is apparent but there appear to be different pathways for different city forms with lower density suburban areas showing the biggest take-up of household-based energy technologies. This suggests a model for the low carbon urban transition involving combinations of simple technological changes and harder structural changes, depending upon which parts of the urban fabric are in focus. This is being called a New Low Carbon Urban Transition Theory.

2018-01-01

This study examined the impact of technology on couples in committed relationships through the lens of the couple and technology framework. Specifically, we used data from 6,756 European couples to examine associations between online boundary crossing, online intrusion, relationship satisfaction, and partner responsiveness. The results suggest that participants' reports of online boundary crossing were linked with lower relationship satisfaction and partner responsiveness. Also, lower relationship satisfaction and partner responsiveness were associated with increased online boundary crossing. The results suggest that men, but not women, who reported greater acceptability for online boundary crossing were more likely to have partners who reported lower relationship satisfaction in their relationships. Implications for clinicians, relationship educators, and researchers are discussed. © 2017 American Association for Marriage and Family Therapy.

Morphology evolution and nanostructure of chemical looping transition metal oxide materials upon redox processes

2017-01-01

Transition metal are heavily used in chemical looping technologies because of their high oxygen carrying capacity and high thermal reactivity. These oxygen activities result in the oxide formation and oxygen vacancy formation that affect the nanoscale crystal phase and morphology within these materials and their subsequent bulk chemical behavior. In this study, two selected earlier transition metals manganese and cobalt as well as two selected later transition metals copper and nickel that are important to chemical looping reactions are investigated when they undergo cyclic redox reactions. We found Co microparticles exhibited increased CoO impurity presence when oxidized to Co_3O_4 upon cyclic oxidation; CuO redox cycles prefer to be limited to a reduced form of Cu_2O and an oxidized form of CuO; Mn microparticles were oxidized to a mixed phases of MnO and Mn_3O_4, which causes delamination during oxidation. For Ni microparticles, a dense surface were observed during the redox reaction. The atomistic thermodynamics methods and density functional theory (DFT) calculations are carried out to elucidate the effect of oxygen dissociation and migration on the morphological evolution of nanostructures during the redox processes. Our results indicate that the earlier transition metals (Mn and Co) tend to have stronger interaction with O_2 than the later transition metals (Ni and Cu). Also, our modified Brønsted−Evans−Polanyi (BEP) relationship for reaction energies and total reaction barriers reveals that reactions of earlier transition metals are more exergonic and have lower oxygen dissociation barriers than those of later transition metals. In addition, it was found that for these transition metal oxides the oxygen vacancy formation energies increase with the depth. The oxide in the higher oxidation state of transition metal has lower vacancy formation energy, which can facilitate forming the defective nanostructures. The fundamental understanding of these metal

To investigate perceived self-efficacy in unemployed young adults with disabilities, and the association between self-efficacy and transition to work or studies. This prospective cohort study collected data through self-report questionnaires and registry data from a vocational rehabilitation project with young adults, aged 19-29 years. The Swedish Social Insurance Agency, the Swedish Public Employment Service and the participating municipalities identified potential participants for the study. A total of 531 participants were included in the study, of which 249 (47%) were available for analysis. Multinomial logistic regression models were carried out to estimate the associations between self-efficacy, demographic (age, country of birth, education level), health and employment status. The latter was coded as: 'no transition to work or studies', 'transition to studies', and 'transition to work'. A higher level of self-efficacy was associated with increased odds for 'transition to work' (OR = 2.37, p young adults with disabilities in order to support their transition and integration into the labour market.

Unexpected Nonlinear Effects in Superconducting Transition-Edge Sensors

Science.gov (United States)

Sadleir, John

2016-01-01

When a normal metal transitions into the superconducting state the DC resistance drops from a finite value to zero over some finite transition width in temperature, current, and magnetic field. Superconducting transition-edge sensors (TESs) operate within this transition region and uses resistive changes to measure deposited thermal energy. This resistive transition is not perfectly smooth and a wide range of TES designs and materials show sub-structure in the resistive transition (as seen in smooth nonmonotonic behavior, jump discontinuities, and hysteresis in the devices current-voltage relation and derivatives of the resistance with respect to temperature, bias current, and magnetic field). TES technology has advanced to the point where for many applications this structure is the limiting factor in performance and optimization consists of finding operating points away from these structures. For example, operating at or near this structure can lead to nonlinearity in the detectors response and gain scale, limit the spectral range of the detector by limiting the usable resistive range, and degrade energy resolution. The origin of much of this substructure is unknown. This presentation investigates a number of possible sources in turn. First we model the TES as a superconducting weak-link and solve for the characteristic differential equations current and voltage time dependence. We find:(1) measured DC biased current-voltage relationship is the time-average of a much higher frequency limit cycle solution.(2) We calculate the fundamental frequency and estimate the power radiated from the TES treating the bias leads as an antennae.(3) The solution for a set of circuit parameters becomes multivalued leading to current transitions between levels.(4)The circuit parameters can change the measure resistance and mask the true critical current. As a consequence the TES resistance surface is not just a function of temperature, current, and magnetic field but is also a

The paper differentiates between 'use', 'need' and 'intended use' to obtain greater precision...... with respect to the technology-market matching process that is fundamental to innovation. The validity of the approach is demonstrated through empirical examples. These examples also show the value of distinguishing between two types of market concept used by the innovating firm.

Transitioning from XML to RDF: Considerations for an effective move towards Linked Data and the Semantic Web

Directory of Open Access Journals (Sweden)

Juliet L. Hardesty

2016-04-01

Full Text Available Metadata, particularly within the academic library setting, is often expressed in eXtensible Markup Language (XML and managed with XML tools, technologies, and workflows. Managing a library’s metadata currently takes on a greater level of complexity as libraries are increasingly adopting the Resource Description Framework (RDF. Semantic Web initiatives are surfacing in the library context with experiments in publishing metadata as Linked Data sets and also with development efforts such as BIBFRAME and the Fedora 4 Digital Repository incorporating RDF. Use cases show that transitions into RDF are occurring in both XML standards and in libraries with metadata encoded in XML. It is vital to understand that transitioning from XML to RDF requires a shift in perspective from replicating structures in XML to defining meaningful relationships in RDF. Establishing coordination and communication among these efforts will help as more libraries move to use RDF, produce Linked Data, and approach the Semantic Web.

Partnerships in Sustainability: The Transition Town Movement in Minnesota

Directory of Open Access Journals (Sweden)

Leslie MacKenzie

2017-06-01

Full Text Available Transition Towns is a citizen-led movement that seeks to address individual and societal dependence on fossil fuels and the need to reduce greenhouse gas production in order to fight climate change. The foundation of Transition is permaculture, a design process based on whole-systems thinking informed by the patterns and relationships found in nature. Since its inception in 2005, the Transition movement has spread worldwide, as people in small groups and across large towns look for ways to take practical action to fight climate change: from home vegetable gardens to weatherization work parties, from time banks and tool shares to renewable energy systems. Transition looks different in every location because it meets the needs and draws on the skills of the local community. This article looks at Transition in one community: The Twin Cities of Minneapolis and St. Paul, profiling several Transition Town groups.

Santisi, Giuseppe; Magnano, Paola; Platania, Silvia; Ramaci, Tiziana

2018-01-01

The phases of career building today bring out a more complex process than in previous decades. Starting from the literature review, the university-to-work transition is considered a very important step in the future career of the graduates, and it involves some psychological resources and requires specific abilities. Research has examined the psychological resources that students at the end of a degree course can use in the university-to-work transition. The aim of the study is to verify the relationship between academic satisfaction and career identity, and the mediational role of readiness and confidence on this relationship. A group of 438 students were assigned to complete a questionnaire in order to examine the relationship between academic satisfaction and career identity and the role of core components of psychological resources: readiness and confidence as mediator. The results indicated both a direct relationship between academic satisfaction and career identity and a mediated relationship with the influence of readiness and confidence for a transition. Adding to our results, we assert that academic satisfaction has a directed effect on confidence during the transition and is a predictor of career identity, both directly and by the mediation of readiness in career transitions. Career identity has implication for exploratory behavior, thus increasing the motivation and mindfulness that create a virtuous circle, influencing the development of knowledge and skills, which are the base of proactivity and confidence in construction of one's future career.

Physical stability of drugs after storage above and below the glass transition temperature: Relationship to glass-forming ability.

2015-11-10

Amorphous materials are inherently unstable and tend to crystallize upon storage. In this study, we investigated the extent to which the physical stability and inherent crystallization tendency of drugs are related to their glass-forming ability (GFA), the glass transition temperature (Tg) and thermodynamic factors. Differential scanning calorimetry was used to produce the amorphous state of 52 drugs [18 compounds crystallized upon heating (Class II) and 34 remained in the amorphous state (Class III)] and to perform in situ storage for the amorphous material for 12h at temperatures 20°C above or below the Tg. A computational model based on the support vector machine (SVM) algorithm was developed to predict the structure-property relationships. All drugs maintained their Class when stored at 20°C below the Tg. Fourteen of the Class II compounds crystallized when stored above the Tg whereas all except one of the Class III compounds remained amorphous. These results were only related to the glass-forming ability and no relationship to e.g. thermodynamic factors was found. The experimental data were used for computational modeling and a classification model was developed that correctly predicted the physical stability above the Tg. The use of a large dataset revealed that molecular features related to aromaticity and π-π interactions reduce the inherent physical stability of amorphous drugs. Copyright © 2015 Elsevier B.V.

Transition strategy of the transportation energy and powertrain in China

International Nuclear Information System (INIS)

Wang Hewu; Ouyang Minggao

2007-01-01

The problems of the transportation energy and environment are the major challenges faced globally in the 21st century and are especially serious for China. The future 20 years is the strategic opportunity period of the transition of the transportation energy and powertrain system for China. The greatest characteristics of hydrogen economy lie in its diversity of the primary energy source, the unification of energy carrier and the greening of energy transformation. Development of hydrogen energy transportation powertrain system is suitable for China from the views of the situation of Chinese resources and energy sources, the urban and rural layouts, the superiority of later development and the successful practices of clean cars and electric vehicle development projects. The transition of the transportation energy powertrain system includes three parts: the transition of the energy structure, the transition of the powertrain system and the transition of the fuel infrastructure. The technical pathways of energy powertrain system transition includes expending the use of gaseous fuel to prompt the multiform of the transportation energy and to prepare for the transition of the infrastructure simultaneously, developing and promoting the hybrid technology to solve the current energy and environment problems and to prepare for the transition of powertrain system, and focusing on the research and development and demonstration of fuel cell vehicles and the hydrogen energy technology to prompt the earlier formation of the market of fuel cell vehicles. The goal in the near and medium term of transition is to reduce the fuel consumption by 100 million ton in 2020 by substituting and saving, and the long-term goal is to setup the infrastructure of hydrogen and fuel cell vehicle as the main one replacing the petroleum internal combustion engine vehicle. In order to realize the strategic goals of the transition, the four-phases strategic periods and research and development

Lung transit of /sup 111/Indium-labelled granulocytes. Relationship to labelling techniques

Energy Technology Data Exchange (ETDEWEB)

Saverymuttu, S.H.; Peters, A.M.; Danpure, H.J.; Reavy, H.J.; Osman, S.; Lavender, J.P. (Hammersmith Hospital, London, England)

1983-01-01

The early in vivo distribution of /sup 111/Indium-labelled granulocytes, recorded by dynamic imaging using a gamma camera and computer, varied according to the separation and labelling technique. Following i.v. bolus injection, 4 kinetic patterns could be identified: (A) rapid transit through the pulmonary vasculature, (B) delayed transit through the lung with clearance by about 30 min, (C) complete retention by the lung, for up to 10 min, followed by slow release over a period of 1 to 2 h, (D) delayed transit through the lung with a similar time course to (B) but with subsequent heavy liver uptake. Granulocytes labelled with /sup 111/In-tropolonate and maintained in plasma throughout the labelling procedure, whether injected as a 'pure' (separated by plasma-enriched density gradient centrifugation) or 'crude' (seprated by differential centrifugation) preparation, displayed type A kinetics, thought to most closely represent the normal behaviour of granulocytes. 'Crude' cells labelled in saline with /sup 111/In-acetylacetonate displayed type B kinetics. 'Pure' cells isolated on Percoll-saline and labelled in saline with /sup 111/In-acetylacetonate displayed type C kinetics, thought to represent granulocyte 'stimulation' and/or damage, or type D kientics, thought to represent severe damage. The importance is stressed of labelling granulocytes for kinetic studies with a technique that results in minimal alteration of cell behaviour.

Equinoctial transitions in the ionosphere and thermosphere

Full Text Available Equinoctial summer/winter transitions in the parameters of the F2-region are analyzed using ground-based ionosonde and incoherent scatter observations. Average transition from one type of diurnal NmF2 variation to another takes 20–25 days, but cases of very fast (6–10 days transitions are observed as well. Strong day-time NmF2 deviations of both signs from the monthly median, not related to geomagnetic activity, are revealed for the transition periods. Both longitudinal and latitudinal variations take place for the amplitude of such quiet time NmF2 deviations. The summer-type diurnal NmF2 variation during the transition period is characterized by decreased atomic oxygen concentration [O] and a small equatorward thermospheric wind compared to winter-type days with strong poleward wind and increased [O]. Molecular N2 and O2 concentrations remain practically unchanged in such day-to-day transitions. The main cause of the F2-layer variations during the transition periods is the change of atomic oxygen abundance in the thermosphere related to changes of global thermospheric circulation. A possible relationship with an equinoctial transition of atomic oxygen at the E-region heights is discussed.Key words.

Finite volume effects on the chiral crossover transition of strong interactions at finite temperature are studied by solving the quark gap equation within a cubic volume of finite size L. With the anti-periodic boundary condition, our calculation shows the chiral quark condensate, which characterizes the strength of dynamical chiral symmetry breaking, decreases as L decreases below 2.5 fm. We further study the finite volume effects on the pseudo-transition temperature {T}{{c}} of the crossover, showing a significant decrease in {T}{{c}} as L decreases below 3 fm.

1974-01-01

A study of the curing reactions of a cycloaliphatic epoxy resin/anhydride system by torsional braid analysis showed the existence of two critical isothermal temperatures - namely, the maximum glass transition temperature of the thermoset system and the glass transition temperature of the material at its gel point. Two rheologically active kinetic transitions occur during isothermal cure which correspond to gelation and vitrification. Three types of isothermal behavior occur. Methods for determining the time to gel and the time to vitrify, and also the two above-mentioned critical isothermal temperatures, have been developed. The time to gel obeyed the Arrhenius relationship, whereas the time to vitrify passed through a minimum. Application of these results to thermosetting systems in general is discussed in terms of the influence of molecular structure on the values of the critical isothermal temperatures.

This report analyses the technological learning and innovation benefits derived from CERN's procurement activity during the period 1997-2001. The base population of our study, the technology-intensive suppliers to CERN, consisted of 629 companies out of 6806 companies during the same period, representing 1197 MCHF in procurement. The main findings from the study can be summarized as follows: the various learning and innovation benefits (e.g., technological learning, organizational capability development, market learning) tend to occur together. Learning and innovation benefits appear to be regulated by the quality of the supplier's relationship with CERN: the greater the amount of social capital built into the relationship, the greater the learning and innovation benefits. Regardless of relationship quality, virtually all suppliers derived significant marketing reference benefits from CERN. Many corollary benefits are associated with procurement activity. As an example, as many as 38% of the respondents devel...

MULTIPLE TRANSITIONS AND HIV RISK AMONG AFRICAN SCHOOL GIRLS

Why are orphaned girls at particular risk of contracting HIV? Using a transition to adulthood framework, this paper uses qualitative data from Nyanza province, Kenya to explore pathways to HIV risk among orphaned and non-orphaned high school girls. I show how co-occurring processes such as residential transition out of the parental home, negotiating financial access and relationship transitions interact to produce disproportionate risk for orphan girls. I also explore the role of financial provision and parental love in modifying girls’ trajectories to risk. I propose a testable theoretical model based on the qualitative findings and suggest policy implications. PMID:21500699

2008-01-01

The transition to a low carbon economy will take decades and affect the entire economy. There is a timely opportunity for investment in energy infrastructure. However, decisions to invest in technologies that are fully aligned with policy and society priorities do not necessarily come naturally, although it will profoundly affect the level of sustainability of the European energy system for decades to come. Technology development needs to be accelerated and prioritized at the highest level of the European policy agenda. This is the essence of the European Strategic Energy Technology Plan (SET-Plan). The SET-Plan makes concrete proposals for action to establish an energy technology policy for Europe, with a new mind-set for planning and working together and to foster science for transforming energy technologies to achieve EU energy and climate change goals for 2020, and to contribute to the worldwide transition to a low carbon economy by 2050. This paper gives an overview of the SET-Plan initiative and highlights its latest developments. It emphasises the importance of information in support of decision-making for investing in the development of low carbon technologies and shows the first results of the technology mapping undertaken by the newly established Information System of the SET-Plan (SETIS).(author)

Transition radiation and transition scattering

International Nuclear Information System (INIS)

Ginzburg, V.L.

1982-01-01

Transition radiation is a process of a rather general character. It occurs when some source, which does not have a proper frequency (for example, a charge) moves at a constant velocity in an inhomogeneous and (or) nonstationary medium or near such a medium. The simplest type of transition radiation takes place when a charge crosses a boundary between two media (the role of one of the media may be played by vacuum). In the case of periodic variation of the medium, transition radiation possesses some specific features (resonance transition radiation or transition scattering). Transition scattering occurs, in particular, when a permittivity wave falls onto an nonmoving (fixed) charge. Transition scattering is closely connected with transition bremsstrahlung radiation. All these transition processes are essential for plasma physics. Transition radiation and transition scattering have analogues outside the framework of electrodynamics (like in the case of Vavilov-Cherenkov radiation). In the present report the corresponding range of phenomena is elucidated, as far as possible, in a generally physical aspect. (Auth.)

The Savannah River Site uses a graded approach to environmental cleanup. The selection of groundwater and vadose zone remediation technologies for a specific contamination area is based on the size, contaminant type, contaminant concentration, and configuration of the plume. These attributes are the result of the nature and mass of the source of contamination and the subsurface characteristics in the area of the plume. Many large plumes consist of several zones that are most efficiently addressed with separate complementary corrective action/remedial technologies. The highest concentrations of contaminants are found in the source zone. The most robust, high mass removal technologies are often best suited for remediation of the source zone. In the primary plume zone, active remedies, such as pump-and-treat, may be necessary to remove contaminants and exert hydraulic control of the plume. In the dilute fringe zone, contaminants are generally lower in concentration and can often be treated with passive techniques. A key determination in achieving an acceptable and cost-effective end state for a given waste unit is when to transition from an active treatment system to a more passive or natural approach (e.g., monitored natural attenuation or enhanced attenuation). This paper will discuss the considerations for such a transition as well as provide examples of successful transitions at the Savannah River Site. (authors)

The energy transition

In a first part, the author proposes an analysis of energy transition and of its consequences on the competitive environment. He recalls the main characteristics of energy transition and more particularly focuses on two aspects: the development of renewable energies and the management of demand. Thus, the author discusses the following issues: the relationship between the struggle against climate change and the low carbon economy, the development of renewable energies, the evolution and main actors of photovoltaic array and of wind turbine production, the distribution of photovoltaic and wind energy installed production among countries, and some key figures about the main renewable energy operators in Europe. He discusses how to manage consumptions, and operations performed. In a second part, the author addresses the impact of the German energy transition (Energiewende) on the business models of the main German energy operators (RWE and E.On). He recalls and comments the objective of this energy policy, presents the German electric and gas sector, comments the evolution of the electric utilities since 1998, more presently presents and discusses the activities of RWE and E.On, the evolution of their main financial indicators, and the levels of installed power with respect of energy sources

Short pauses or "transition-periods" at the end of expiration and prior to subsequent inspiration are commonly observed during sleep in humans. However, the role of transition periods in regulating ventilation during physiological challenges such as partial airway obstruction (PAO) has not been investigated. Twenty-nine obstructive sleep apnea patients and eight controls underwent overnight polysomnography with an epiglottic catheter. Sustained-PAO segments (increased epiglottic pressure over ≥5 breaths without increased peak inspiratory flow) and unobstructed reference segments were manually scored during apnea-free non-REM sleep. Nasal pressure data was computationally segmented into inspiratory (T I , shortest period achieving 95% inspiratory volume), expiratory (T E , shortest period achieving 95% expiratory volume), and inter-breath transition period (T Trans , period between T E and subsequent T I ). Compared with reference segments, sustained-PAO segments had a mean relative reduction in T Trans (-24.7±17.6%, P<0.001), elevated T I (11.8±10.5%, P<0.001), and a small reduction in T E (-3.9±8.0, P≤0.05). Compensatory increases in inspiratory period during PAO are primarily explained by reduced transition period and not by reduced expiratory period. Copyright © 2017 Elsevier B.V. All rights reserved.

Causal Dynamic Relationships between Political–Economic Factors and Export Performance in the Renewable Energy Technologies Market

Directory of Open Access Journals (Sweden)

Bongsuk Sung

2018-04-01

Full Text Available This study explores how political–economic forces could affect export performance in the renewable energy technologies market. We conduct panel framework analyses to verify the characteristics of panel data for 19 countries before establishing the panel estimator meant to test the effects of political–economic forces on export specialization. We consider the results of the panel framework analyses and develop an empirical model to test casual dynamic relationships between political–economic forces and export performance. The results from the least squares dummy variable-corrected estimation indicate that the major factors promoting the export specialization of renewable energy technologies are, in order of decreasing importance, public pressure, market size, and government demand-pull policy. However, the traditional energy industry has no significant effect on export performance. Finally, this study finds that dynamic effects exist in all estimations.

One of the most important factors that makes the transition from secondary school to medical school challenging is the inability to put in the study time that a medical school curriculum demands. The implementation of regulated learning is essential for students to cope with medical course environment and succeed. This study aimed to investigate the reciprocal relationships between self-regulated learning skills (SRLS) and academic workload (AW) across secondary school to medical school transition. Freshmen enrolled in medical school (N = 102) completed questionnaires at the beginning and at the end of their academic year, assessing AW (measured as study time hours and perceived workload), SRLS (planning and strategies for learning assessment, motivation and action to learning and self-directedness) and academic achievement. An exploratory factor analysis (EFA) and a longitudinal path analysis were performed. According to the EFA, study time and perceived workload revealed two factors of AW: students who had a high perceived workload also demonstrated increased study time (tandem AW); and those who had a low perceived workload also demonstrated increased study time (inverse AW). Only a longitudinal relationship between SRLS and AW was found in the path analysis: prior self-directedness was related to later tandem AW. Moreover, success during the first year of medical school is dependent on exposure to motivation, self-directedness and high study time without overload during secondary school and medical school, and prior academic achievement. By better understanding these relationships, teachers can create conditions that support academic success during the first year medical school.

2017-11-01

The transition to the sustainable development posed new challenges to the system of mining higher education. They are determined by the acceleration of scientific and technological progress and widespread introduction of innovations, convergence of technologies from various industries. On the one hand, globalization and rapid technology development are constantly increasing quality requirements for the labor resources of the mineral and raw materials complex and constant improvement of their skills. On the other hand, the transition to the sustainable development provides the necessity for rational use of raw materials and environmental protection. This requires the improvement of staff support system for mining operations and the interaction of enterprises with universities training mining engineers, aimed at the innovative competencies development of future miners.

2018-01-01

The process of gender transition has varying effects on various aspects of sexuality. The purpose of this study was to investigate the effects of transitioning on transgender persons' sexual preferences and partnerships. Data were collected through an anonymous online survey. Questions focused on timing of gender transition in relation to change in sexual preference. Transgender individuals have a variety of sexual partners, predominantly cisgender, and may change sexual preference when they transition. Transitioning can be associated with having no primary sexual partner, despite past sexual partnerships. Length of time between identifying as transgender and starting the transition might be associated with changing sexual partner preference, particularly in transgender women. The emerging trends of sexual partnerships and changing sexual preferences related to the transition in this study warrant further investigation. These data provide more understanding of the relationship between transitioning and sexual preferences and partnerships.

Expectations of millennial nurse graduates transitioning into practice.

Identified as Millennials, nurses born after 1980 are anticipated to redefine the employer-employee relationship as one based on the employee's wants and needs. The purpose of this study is to portray the expectations of Millennial student nurses immediately before graduation. Understanding these expectations may provide insight for leaders who are responsible for crafting a successful transition experience. Successful transition and decreased turnover are important elements of cost management for the nursing enterprise. A qualitative descriptive design was used to collect data from 14 students enrolled in a traditional BSN academic nursing program approximately 2 months prior to graduation. Upon completion of private, confidential semistructured interviews, data were transcribed, coded, and analyzed. Demographic data were compiled and interview data summarized according to identified themes. Three overarching themes emerged: the expectation that transition would be stressful, the expectation that there would be a safety net of support, and the expectation to be valued and respected as a professional. Revealing was the expectation of supportive relationships and a collaborative approach to patient care. Failure to meet those expectations may result in turnover as Millennials seek opportunities that meet their expectations.

It is demonstrated that the transition temperature (T{sub C}) of high-T{sub C} superconductors is determined by their layered crystal structure, bond lengths, valency properties of the ions, and Coulomb coupling between electronic bands in adjacent, spatially separated layers. Analysis of 31 high-T{sub C} materials (cuprates, ruthenates, ruthenocuprates, iron pnictides, organics) yields the universal relationship for optimal compounds, k{sub B}T{sub C0} ={beta}/{iota}{zeta}, where {iota} is related to the mean spacing between interacting charges in the layers, {zeta} is the distance between interacting electronic layers, {beta} is a universal constant and T{sub C0} is the optimal transition temperature (determined to within an uncertainty of {+-} 1.4 K by this relationship). Non-optimum compounds, in which sample degradation is evident, e.g. by broadened superconducting transitions and diminished Meissner fractions, typically exhibit reduced T{sub C} < T{sub C0}. It is shown that T{sub C0} may be obtained from an average of the Coulomb interaction forces between the two layers.

Unintended Side Effects of the Digital Transition: European Scientists’ Messages from a Proposition-Based Expert Round Table

Full Text Available We present the main messages of a European Expert Round Table (ERT on the unintended side effects (unseens of the digital transition. Seventeen experts provided 42 propositions from ten different perspectives as input for the ERT. A full-day ERT deliberated communalities and relationships among these unseens and provided suggestions on (i what the major unseens are; (ii how rebound effects of digital transitioning may become the subject of overarching research; and (iii what unseens should become subjects of transdisciplinary theory and practice processes for developing socially robust orientations. With respect to the latter, the experts suggested that the “ownership, economic value, use and access of data” and, related to this, algorithmic decision-making call for transdisciplinary processes that may provide guidelines for key stakeholder groups on how the responsible use of digital data can be developed. A cluster-based content analysis of the propositions, the discussion and inputs of the ERT, and a theoretical analysis of major changes to levels of human systems and the human–environment relationship resulted in the following greater picture: The digital transition calls for redefining economy, labor, democracy, and humanity. Artificial Intelligence (AI-based machines may take over major domains of human labor, reorganize supply chains, induce platform economics, and reshape the participation of economic actors in the value chain.

Shaw, James A; Kontos, Pia; Martin, Wendy; Victor, Christina

2017-03-20

Purpose The purpose of this paper is to use theories of institutional logics and institutional entrepreneurship to examine how and why macro-, meso-, and micro-level influences inter-relate in the implementation of integrated transitional care out of hospital in the English National Health Service. Design/methodology/approach The authors conducted an ethnographic case study of a hospital and surrounding services within a large urban centre in England. Specific methods included qualitative interviews with patients/caregivers, health/social care providers, and organizational leaders; observations of hospital transition planning meetings, community "hub" meetings, and other instances of transition planning; reviews of patient records; and analysis of key policy documents. Analysis was iterative and informed by theory on institutional logics and institutional entrepreneurship. Findings Organizational leaders at the meso-level of health and social care promoted a partnership logic of integrated care in response to conflicting institutional ideas found within a key macro-level policy enacted in 2003 (The Community Care (Delayed Discharges) Act). Through institutional entrepreneurship at the micro-level, the partnership logic became manifest in the form of relationship work among health and social care providers; they sought to build strong interpersonal relationships to enact more integrated transitional care. Originality/value This study has three key implications. First, efforts to promote integrated care should strategically include institutional entrepreneurs at the organizational and clinical levels. Second, integrated care initiatives should emphasize relationship-building among health and social care providers. Finally, theoretical development on institutional logics should further examine the role of interpersonal relationships in facilitating the "spread" of logics between macro-, meso-, and micro-level influences on inter-organizational change.

Socio-technical transition as a co-evolutionary process: Innovation and the role of niche markets in the transition to motor vehicles

Science.gov (United States)

Birky, Alicia K.

2008-10-01

Significant reductions in greenhouse emissions from personal transportation will require a transition to an alternative technology regime based on renewable energy sources. Two bodies of research, the quasi-evolutionary (QE) model and the multi-level perspective (MLP) assert that processes within niches play a fundamental role in such transitions. This research asks whether the description of transitions based on this niche hypothesis and its underlying assumptions is consistent with the historical U.S. transition to motor vehicles at the beginning of the 20th century. Unique to this dissertation is the combination of the perspective of the entrepreneur with co-evolutionary approaches to socio-technical transitions. This approach is augmented with concepts from the industry life-cycle model and with a taxonomy of mechanisms of learning. Using this analytic framework, I examine specifically the role of entrepreneurial behavior and processes within and among firms in the co-evolution of technologies and institutions during the transition to motor vehicles. I find that niche markets played an important role in the development of the technology, institutions, and the industry. However, I also find that the diffusion of the automobile is not consistent with the niche hypothesis in the following ways: (1) product improvements and cost reductions were not realized in niche markets, but were achieved simultaneously with diffusion into mass markets; (2) in addition to learning-by-doing and learning-by-interacting with users, knowledge spillovers and interacting with suppliers were critical in this process; (3) cost reductions were not automatic results of expanding markets, but rather arose from the strategies of entrepreneurs based on personal perspectives and values. This finding supports the use of a behavioral approach with a micro-focus in the analysis of socio-technical change. I also find that the emergence and diffusion of the motor vehicle can only be understood by

Full Text Available Giuseppe Santisi,1 Paola Magnano,2 Silvia Platania,1 Tiziana Ramaci2 1Department of Educational Sciences, University of Catania, Catania, Italy; 2Faculty of Human and Social Sciences, “Kore” University of Enna, Enna, Italy Background: The phases of career building today bring out a more complex process than in previous decades. Starting from the literature review, the university-to-work transition is considered a very important step in the future career of the graduates, and it involves some psychological resources and requires specific abilities. Methods: Research has examined the psychological resources that students at the end of a degree course can use in the university-to-work transition. The aim of the study is to verify the relationship between academic satisfaction and career identity, and the mediational role of readiness and confidence on this relationship. A group of 438 students were assigned to complete a questionnaire in order to examine the relationship between academic satisfaction and career identity and the role of core components of psychological resources: readiness and confidence as mediator. Results: The results indicated both a direct relationship between academic satisfaction and career identity and a mediated relationship with the influence of readiness and confidence for a transition. Adding to our results, we assert that academic satisfaction has a directed effect on confidence during the transition and is a predictor of career identity, both directly and by the mediation of readiness in career transitions. Conclusion: Career identity has implication for exploratory behavior, thus increasing the motivation and mindfulness that create a virtuous circle, influencing the development of knowledge and skills, which are the base of proactivity and confidence in construction of one’s future career. Keywords: career, transition, identity, satisfaction, resources

Bouck, Emily C; Flanagan, Sara M

2016-11-01

This study sought to understand the extent to which students with severe disabilities receive assistive technology in school and out-of-school, and the relationship between receipt of assistive technology in school and post-school outcomes for these students. This study was a secondary analysis of the National Longitudinal Transition Study-2 (NLTS2) from the USA. To analyze the data in this correlational study, researchers conducted frequency distributions, Chi Square Tests of Associations, significance tests and logistic regressions. The main results suggest (a) receipt of assistive technology in school varied greatly by disability identification; (b) receipt of assistive technology post-school also varied by disability identification, but receipt was generally lower; and (c) few statistically significant post-school outcome differences existed between students who received assistive technology and those who did not. An under-utilization of assistive technology exists in practice in the USA for students with severe disabilities. Implications for Rehabilitation An under-utilization of assistive technology for secondary students and adults with severe disabilities likely exists. A need exists for improved collaboration between professionals in rehabilitation and professionals in schools to ensure continuation of needed services or aids, such as assistive technology. Additional research is needed to better understand the adult life (or post-school) outcomes of individuals with severe disabilities, factors from PK-12 schooling or post-school services that positively and negative impact those outcomes.

Nyborg, Sophie; Borch, Kristian; Bentzen, Martin Mose

Notions of "smart energy systems" are pervasive in discussions of a low carbon transition and much work is devoted to developing "smart energy technologies" and analyzing their economic potential. However, users, i.e. civil society receive only little attention and are mainly described as "energy...... consumers". The aim of this research project is to explore how civil society can get a more active role in the transition towards a low carbon energy system. Through qualitative case-study methods and scenario work, we explore the role of "energy users" for the innovative design and development of large...... technological systems. We ask whether the envisioned smart energy systems have potential to support more active innovation roles for the individuals using energy systems than what have been described by previous studies. Moreover, we discuss whether and how such roles allow for a democratic as well as socially...

Technological Singularity: What Do We Really Know?

Directory of Open Access Journals (Sweden)

Alexey Potapov

2018-04-01

Full Text Available The concept of the technological singularity is frequently reified. Futurist forecasts inferred from this imprecise reification are then criticized, and the reified ideas are incorporated in the core concept. In this paper, I try to disentangle the facts related to the technological singularity from more speculative beliefs about the possibility of creating artificial general intelligence. I use the theory of metasystem transitions and the concept of universal evolution to analyze some misconceptions about the technological singularity. While it may be neither purely technological, nor truly singular, we can predict that the next transition will take place, and that the emerged metasystem will demonstrate exponential growth in complexity with a doubling time of less than half a year, exceeding the complexity of the existing cybernetic systems in few decades.

Assessing the dynamic material criticality of infrastructure transitions: A case of low carbon electricity

International Nuclear Information System (INIS)

Roelich, Katy; Dawson, David A.; Purnell, Phil; Knoeri, Christof; Revell, Ruairi; Busch, Jonathan; Steinberger, Julia K.

2014-01-01

Highlights: • We present a method to analyse material criticality of infrastructure transitions. • Criticality is defined as the potential for, and exposure to, supply disruption. • Our method is dynamic reducing the probability of lock-in to at-risk technologies. • We show that supply disruption potential is reducing but exposure is increasing. - Abstract: Decarbonisation of existing infrastructure systems requires a dynamic roll-out of technology at an unprecedented scale. The potential disruption in supply of critical materials could endanger such a transition to low-carbon infrastructure and, by extension, compromise energy security more broadly because low carbon technologies are reliant on these materials in a way that fossil-fuelled energy infrastructure is not. Criticality is currently defined as the combination of the potential for supply disruption and the exposure of a system of interest to that disruption. We build on this definition and develop a dynamic approach to quantifying criticality, which monitors the change in criticality during the transition towards a low-carbon infrastructure goal. This allows us to assess the relative risk of different technology pathways to reach a particular goal and reduce the probability of being ‘locked in’ to currently attractive but potentially future-critical technologies. To demonstrate, we apply our method to criticality of the proposed UK electricity system transition, with a focus on neodymium. We anticipate that the supply disruption potential of neodymium will decrease by almost 30% by 2050; however, our results show the criticality of low carbon electricity production increases ninefold over this period, as a result of increasing exposure to neodymium-reliant technologies

Contestation, contingency, and justice in the Nordic low-carbon energy transition

International Nuclear Information System (INIS)

Sovacool, Benjamin K.

2017-01-01

The five Nordic countries have aggressive climate and energy policies in place and have already emerged to be leaders in renewable energy and energy efficiency. Denmark is renowned for its pioneering use of wind energy, Finland and Sweden bioenergy, Norway hydroelectricity and Iceland geothermal energy. All countries aim to be virtually “fossil free” by 2050. This study explores the Nordic energy transition through the lens of three interconnected research questions: How are they doing it? What challenges exist? And what broader lessons result for energy policy? The study firstly investigates the pathways necessary for these five countries to achieve their low-carbon goals. It argues that a concerted effort must be made to (1) promote decentralized and renewable forms of electricity supply; (2) shift to more sustainable forms of transport; (3) further improve the energy efficiency of residential and commercial buildings; and (4) adopt carbon capture and storage technologies for industry. However, the section that follows emphasizes some of the empirical barriers the Nordic transition must confront, namely political contestation, technological contingency, and social justice and recognition concerns. The study concludes with implications for what such historical progress, and future transition pathways, mean for both energy researchers and energy planners. - Highlights: • Nordic countries have strong energy and climate policies to be practically “fossil free” by 2050. • Decarbonization and transition pathways depend on renewable energy, efficiency, transport, and industry. • The Nordic transition remains contingent on further technological innovations and policy commitments. • It also raises energy justice issues concerning employment, public knowledge, and embodied emissions.

This report reports the result of the fiscal 1998 R and D on femtosecond technology supported by NEDO. For creation of industrial basic technologies supporting the advanced information society in the 21st century, ultra-high speed electronics technology including new functions beyond the speed limit of conventional electronics technologies is indispensable. From such viewpoint, this R and D aims at establishment of the basic technology necessary for ultra- high speed electronics technology through R and D of technology controlling conditions of beams and electrons in a femtosecond (10{sup -15}-10{sup -12} seconds) region. In fiscal 1998, this project first succeeded in fabrication of a prototype pulse compressor by using semiconductors, and developed a new pulse compressing method by using fibers to generate ultra-short pulse of 38fs. By developing new materials for intersubband transition where ultra-high speed responses can be expected, optical absorption by intersubband transition was first confirmed at optical communication wavelength. The main result for every theme is reported and explained. (NEDO)

A conceptual framework for exploring transitions to decarbonised energy systems in the United Kingdom

International Nuclear Information System (INIS)

Shackley, Simon; Green, Ken

2007-01-01

Drawing upon 'transitions theory' and a typology which produces five types of transitions, we describe and analyse the changes that have taken place in the United Kingdom's energy system over the past several decades in terms of three of these transition pathways, namely reproduction (e.g. incremental improvements in energy efficiency), transformation (e.g. more directed efforts towards energy efficiency gains, e.g., through voluntary and compulsory standards-setting processes) and substitution (e.g. the shift from coal to natural gas). Looking into the future, and drawing upon a programme of UK-based research which covered a wide range of potential new supply technologies and changes on the demand side, we identify the key drivers of change, including economic and commercial, technological, policy and regulatory imperatives. This analysis opens up the prospect for two further transition pathways to become manifest. These are: de-alignment/re-alignment (e.g. shift from conventional coal to coal technologies with carbon dioxide capture and storage) and re-configuration (e.g. integrating renewables within buildings and the possible emergence of the 'hydrogen economy'). We conclude with a discussion of the opportunities for policy learning and experimentation consistent with transitions theory to facilitate the deployment of more sustainable energy systems

Linking age, survival, and transit time distributions

Science.gov (United States)

Calabrese, Salvatore; Porporato, Amilcare

2015-10-01

Although the concepts of age, survival, and transit time have been widely used in many fields, including population dynamics, chemical engineering, and hydrology, a comprehensive mathematical framework is still missing. Here we discuss several relationships among these quantities by starting from the evolution equation for the joint distribution of age and survival, from which the equations for age and survival time readily follow. It also becomes apparent how the statistical dependence between age and survival is directly related to either the age dependence of the loss function or the survival-time dependence of the input function. The solution of the joint distribution equation also allows us to obtain the relationships between the age at exit (or death) and the survival time at input (or birth), as well as to stress the symmetries of the various distributions under time reversal. The transit time is then obtained as a sum of the age and survival time, and its properties are discussed along with the general relationships between their mean values. The special case of steady state case is analyzed in detail. Some examples, inspired by hydrologic applications, are presented to illustrate the theory with the specific results. This article was corrected on 11 Nov 2015. See the end of the full text for details.

High-Density Quantum Sensing with Dissipative First Order Transitions

Science.gov (United States)

Raghunandan, Meghana; Wrachtrup, Jörg; Weimer, Hendrik

2018-04-01

The sensing of external fields using quantum systems is a prime example of an emergent quantum technology. Generically, the sensitivity of a quantum sensor consisting of N independent particles is proportional to √{N }. However, interactions invariably occurring at high densities lead to a breakdown of the assumption of independence between the particles, posing a severe challenge for quantum sensors operating at the nanoscale. Here, we show that interactions in quantum sensors can be transformed from a nuisance into an advantage when strong interactions trigger a dissipative phase transition in an open quantum system. We demonstrate this behavior by analyzing dissipative quantum sensors based upon nitrogen-vacancy defect centers in diamond. Using both a variational method and a numerical simulation of the master equation describing the open quantum many-body system, we establish the existence of a dissipative first order transition that can be used for quantum sensing. We investigate the properties of this phase transition for two- and three-dimensional setups, demonstrating that the transition can be observed using current experimental technology. Finally, we show that quantum sensors based on dissipative phase transitions are particularly robust against imperfections such as disorder or decoherence, with the sensitivity of the sensor not being limited by the T2 coherence time of the device. Our results can readily be applied to other applications in quantum sensing and quantum metrology where interactions are currently a limiting factor.

The sensing of external fields using quantum systems is a prime example of an emergent quantum technology. Generically, the sensitivity of a quantum sensor consisting of N independent particles is proportional to sqrt[N]. However, interactions invariably occurring at high densities lead to a breakdown of the assumption of independence between the particles, posing a severe challenge for quantum sensors operating at the nanoscale. Here, we show that interactions in quantum sensors can be transformed from a nuisance into an advantage when strong interactions trigger a dissipative phase transition in an open quantum system. We demonstrate this behavior by analyzing dissipative quantum sensors based upon nitrogen-vacancy defect centers in diamond. Using both a variational method and a numerical simulation of the master equation describing the open quantum many-body system, we establish the existence of a dissipative first order transition that can be used for quantum sensing.

Finally, we show that quantum sensors based on dissipative phase transitions are particularly robust against imperfections such as disorder or decoherence, with the sensitivity of the sensor not being limited by the T_{2} coherence time of the device.

2008-02-01

OBJECTIVES Part I: To determine factors associated with reported joint symptoms across the menopausal transition. Part II: To investigate the relationship between symptom reporting and radiological arthritis in postmenopausal women. DESIGN Part I: The Melbourne Women's Mid-life Health Project, commenced in 1991, is a population-based prospective study of 438 Australian-born women, aged 45-55 years and menstruating at baseline; they were interviewed annually over 8 years. The retention rate was 88% (n = 387). Part II: After 12 years of follow-up, 257 (57%) women returned for assessment and 224 agreed to undergo X-rays of their hands and knees. METHODS Part I: Annual fasting blood collection, physical measurements, and interviews including questions about bothersome aches or stiff joints in the previous 2 weeks. A score for this symptom was calculated from the product of the severity and frequency data. These data were analyzed using random-effects time-series regression models. Part II: X-rays were scored for evidence of osteoarthritis using a validated scale, by two investigators who were blinded to questionnaire results. RESULTS Part I: 'Aches and stiff joints' were the most commonly reported symptom and reporting increased over time in the longitudinal study. Variables significantly associated with reporting bothersome aches and stiff joints were high body mass index (BMI) (p Part II: The relationship between radiological osteoarthritis and symptom reports approached statistical significance (p = 0.06). Knee osteoarthritis was significantly associated with symptom reports (p = 0.008) but not hand osteoarthritis (p = 0.2). Menopausal status, BMI, employment status and depressed mood were all associated with the experience of bothersome aches and stiff joints. Aches and stiff joints, common in postmenopausal women, are not necessarily indicative of radiological osteoarthritis.

Order parameters for symmetry-breaking structural transitions: The tetragonal-monoclinic transition in ZrO2

Science.gov (United States)

Thomas, John C.; Van der Ven, Anton

2017-10-01

Group/subgroup structural phase transitions are exploited in a wide variety of technologies, including those that rely on shape-memory behavior and on transformation toughening. Here, we introduce an approach to identify symmetry-adapted strain and shuffle order parameters for any group/subgroup structural transition between a high-symmetry parent phase and its symmetrically equivalent low-symmetry product phases. We show that symmetry-adapted atomic shuffle order parameters can be determined by the diagonalization of an orbital covariance matrix, formed by taking the covariance among the atomic displacement vectors of all symmetrically equivalent product phase variants. We use this approach to analyze the technologically important tetragonal to monoclinic structural phase transformation of ZrO2. We explore the energy landscapes, as calculated with density functional theory, along distinct paths that connect m ZrO2 to t ZrO2 and to other m ZrO2 variants. The calculations indicate favorable pairs of variants and reveal intermediate structures likely to exist at coherent twin boundaries and having relatively low deformation energy. We identify crystallographic features of the monoclinic ZrO2 variant that make it very sensitive to shape changing strains.

Parenting in On/Off Relationships: The Link Between Relationship Churning and Father Involvement.

Science.gov (United States)

Turney, Kristin; Halpern-Meekin, Sarah

2017-06-01

Family systems theory points to the interconnected nature of dyadic relationships within the family unit, arguing for attention to how the parental relationship shapes their ties to and interactions with their children. Grounded in family systems theory, we consider how relationship churning-defined as being in an on-again/off-again relationship with the same partner-is associated with father involvement. We use data from the Fragile Families and Child Wellbeing Study to examine how father involvement among relationship churners compares with father involvement among those in three other relationship types (measured during the first five years of the focal child's life): stably together relationships, stably broken-up relationships, and repartnered relationships. First, we find that churning fathers remain more involved with their 9-year-old children than do parents who stably break up or repartner, but they are less involved than those who are stably together. Second, lower relationship quality among churners-and, to a lesser extent, repartnering and childbearing with a new partner-explains some of the differences in father involvement between churners and the stably together. Third, these differences are most apparent among parents not living together when father involvement is measured. Taken together, the focus on relationship churning extends prior research on the association between relationship transitions and father involvement by separating relationship instability from partner change.

Capturing Complexities of Relationship-Level Family Planning Trajectories in Malawi.

Science.gov (United States)

Furnas, Hannah E

2016-09-01

In a transitioning fertility climate, preferences and decisions surrounding family planning are constantly in flux. Malawi provides an ideal case study of family planning complexities as fertility preferences are flexible, the relationship context is unstable, and childbearing begins early. I use intensive longitudinal data from Tsogolo la Thanzi-a research project in Malawi that follows young adults in romantic partnerships through the course of their relationship. I examine two questions: (1) What are the typical patterns of family planning as young adults transition through a relationship? (2) How are family planning trajectories related to individual and relationship-level characteristics? I use sequence analysis to order family planning across time and to contextualize it within each relationship. I generate and cluster the family planning trajectories and find six distinct groups of young adults who engage in family planning in similar ways. I find that family planning is complex, dynamic, and unique to each relationship. I argue that (a) family planning research should use the relationship as the unit of analysis and (b) family planning behaviors and preferences should be sequenced over time for a better understanding of key concepts, such as unmet need. © 2016 The Population Council, Inc.

Guiding a transition to low carbon electricity requires a good understanding of the substitution of old by new technologies in the electricity industry. With the aim of explaining historical change from coal to gas in the British electricity industry, we develop a formal model of technological change, where energy technologies diffuse through the construction of new power plants. We considered two model versions: with rational and boundedly rational investors. In each model version, we look at the causal relations between price and output setting mechanisms, fuel and labour use, and investment decisions for different institutional arrangements. We quantify model parameters on data for the United Kingdom. We find that the version of the model with rational investors is capable of replicating well core features of UK electricity history. This includes a rapid diffusion of gas in electricity production, the evolution of the average size of newly installed plants, and a high percentage of electricity sales covered by (forward) contracts-for-difference. In this model setting, nuclear and renewable energies have no chance to diffuse on the market. In the version of the model with boundedly rational investors, nuclear power typically dominates electricity production. We discuss implications of our modelling results for making a transition to low carbon electricity in the future. - Highlights: > We propose a model of a transition from coal to gas in electricity production. > Energy technologies diffuse through the construction of new power plants. > We considered two model versions: with rational and boundedly rational investors. > We quantify model parameters on data for the UK for the period 1990-2002. > We draw policy conclusions for guiding a transition to low carbon electricity.

In each model version, we look at the causal relations between price and output setting mechanisms, fuel and labour use, and investment decisions for different institutional arrangements. We quantify model parameters on data for the United Kingdom. We find that the version of the model with rational investors is capable of replicating well core features of UK electricity history. This includes a rapid diffusion of gas in electricity production, the evolution of the average size of newly installed plants, and a high percentage of electricity sales covered by (forward) contracts-for-difference. In this model setting, nuclear and renewable energies have no chance to diffuse on the market. In the version of the model with boundedly rational investors, nuclear power typically dominates electricity production. We discuss implications of our modelling results for making a transition to low carbon electricity in the future. - Highlights: → We propose a model of a transition from coal to gas in electricity production. → Energy technologies diffuse through the construction of new power plants. → We considered two model versions: with rational and boundedly rational investors. → We quantify model parameters on data for the UK for the period 1990-2002. → We draw policy conclusions for guiding a transition to low carbon electricity.

Achieving long-term targets for greenhouse gas emissions reductions, such as the UK's legally-binding target of reducing its emissions by 80% by 2050, will require a transition in systems for meeting and shaping energy service demands, involving radical substitution to low-carbon supply technologies and improvements in end-use energy efficiency. This paper describes the development and high-level analysis of a set of transition pathways to a UK low carbon electricity system, explaining key features of the core pathways developed and the distinctiveness and value of the approach. The pathways use an ‘action space’ concept to explore the dynamic interactions between choices made by actors, which are influenced by the competing governance ‘framings’ or ‘logics’ that different actors pursue. The paper sets out three core transition pathways – Market Rules, Central Co-ordination and Thousand Flowers, in which market, government and civil society logics respectively dominate. It summarises the key technological and institutional changes in these pathways, and the roles of actors in bringing these about. This leads to an identification of the key risks to the realisation of each of the pathways, and of the challenges for individuals, businesses, social movements and policy-makers in taking action to bring them about and sustain them. - Highlights: ► Development of a set of transition pathways to a UK low carbon electricity system. ► Action space to explore the dynamic interactions between choices made by actors. ► Three core pathways in which market, government and civil society logics dominate. ► Key technological and institutional changes, and the roles of actors in pathways. ► Challenges for different actors in realising pathways.

Strategies for implementing transit priority

International Nuclear Information System (INIS)

2005-11-01

Increased urbanization in Canada has placed pressure on an eroding, ageing infrastructure and raised concerns about declining air quality. In addition to reducing emissions, well-designed transit systems can reduce traffic and improve road safety. This paper presented a set of transit best practices which addressed the need to improve supply, influence demand, and make operational improvements with the least environmental impact. The objective of this paper was to gather the best implementation strategies for urban roads from municipalities across Canada, and to focus on solutions that can be applied to bus and streetcar systems to make better use of shared facilities. Bus bulbs, signal priority, queue jumps and green waves were recommended, as well as dedicated lanes and exclusive transit facilities. Advances in technology were reviewed, as well as the use of intelligent transportation systems to improve transit with little or no impact on other road users. Case studies were presented from various municipalities across Canada. Various stages of project development, design and construction, operations and maintenance strategies for the various projects were reviewed. The most successful installations were found to be in cities that have established a clear policy on transit improvements. It was suggested that defining the need for priority and determining where it can be implemented is central to the development of a strategic program. Dedicated programs looking at transit priority were recommended, and risks arising from integrating new infrastructure were reviewed. It was suggested that the range of stakeholders involved, and the internal organization of the implementing authority bore a significant impact on overall cost and schedule of transit projects. It was concluded that appropriate planning is needed to control risks. 20 refs., 3 figs

Household transitions to energy efficient lighting

New energy efficient lighting technologies can significantly reduce household electricity consumption, but adoption has been slow. A unique dataset of German households is used in this paper to examine the factors associated with the replacement of old incandescent lamps (ILs) with new energy efficient compact fluorescent lamps (CFLs) and light emitting diodes (LEDs). The ‘rebound’ effect of increased lamp luminosity in the transition to energy efficient bulbs is analyzed jointly with the replacement decision to account for household self-selection in bulb-type choice. Results indicate that the EU ban on ILs accelerated the pace of transition to CFLs and LEDs, while storage of bulbs significantly dampened the speed of the transition. Higher lighting needs and bulb attributes like energy efficiency, environmental friendliness, and durability spur IL replacement with CFLs or LEDs. Electricity gains from new energy efficient lighting are mitigated by 23% and 47% increases in luminosity for CFL and LED replacements, respectively. Model results suggest that taking the replacement bulb from storage and higher levels of education dampen the magnitude of these luminosity rebounds in IL to CFL transitions. - Highlights: • EU ban on ILs has fostered transitions to energy efficient lighting • Energy efficient, environmentally friendly, and durable lighting preferences make CFL and LED transitions more likely • Indicators of greater lighting needs are associated with higher propensities to replace ILs with CFLs and LEDs • For residential lighting, the rebound effect manifests itself through increases in luminosity • In IL to CLF transitions luminosity increases are lower with higher levels of education

The process and preparation of moving from child to adult services (transition) is a challenging period of time for young people and represents significant changes in care and support systems. The proliferation of mobile phone applications for health purposes suggests that it is an area for further investigation. The review explores the potential to use mobile phone technology to help support young liver transplant recipients moving to adult services. It represents the first review conducted in this specialism and considers a new model of support for young liver patients. A systematic rapid review of the published peer-reviewed literature. Two searches were conducted: Search 1: the use of technology to support transition to adult services (6 studies) and Search 2: how best to support liver transplant recipients during transition (6 studies). Research shows that to achieve positive transition young people need information about their condition and transition. The process needs to be guided by transition readiness, rather than the young persons' age. Although parents and support networks should be in place and are valued, transition should build upon self-management and independence. Results suggest that there appears to be scope to use mobile phone technology to support transition. This is the first time a review has explored the types of issues or concerns facing liver transplant patients and how these can be addressed through mobile phone technology.

US activities on fuel cycle transition scenarios

McCarthy, Kathryn A.

Countries with active nuclear programmes typically have as a goal transition to a closed fuel cycle. A closed fuel cycle enables long-term sustainability, provides waste management benefits, and as a system, can reduce overall proliferation risk. This transition will take many decades, thus the study of the actual transition is an important topic. The United States systems analysis activities as part of the Advanced Fuel Cycle Initiative (AFCI) provide the integrating analyses for the fuel cycle programme, and recent activities are focusing on transition options, and specifically, the dynamics of the transition. The United States is still studying both one-tier (recycling in fast reactors only) and two-tier (recycling in both thermal and fast reactors) systems, and the systems analysis activities provide insight into the trade-offs associated with the systems, and variations of each. Most recently, a series of sensitivity studies have been completed which provide insight into the behaviour of a transition system. These studies evaluate the impact of changing various parameters in the fuel cycle system, and provide insight into how the system will change as parameters change. Because these deployment analyses look at the development of nuclear energy systems over a long period of time, it is very unlikely that we will accurately predict the system's characteristics over time (for example, growth in electricity demand, how quickly nuclear reactors will be deployed, how many fast rectors versus thermal reactors, the conversion ratio of the fast reactors, etc.). How the system will develop will depend on a variety of factors, ranging from political to technical, rational to irrational. Because we cannot accurately predict the future, we need to understand how things could change, and what impact those changes have. Analyses of future fuel cycle systems require a number of assumptions. These include growth rates for nuclear energy, general architecture of fuel cycle

How to quantify the transition phase during golf swing performance: Torsional load affects low back complaints during the transition phase.

The transition phase of a golf swing is considered to be a decisive instant required for a powerful swing. However, at the same time, the low back torsional loads during this phase can have a considerable effect on golf-related low back pain (LBP). Previous efforts to quantify the transition phase were hampered by problems with accuracy due to methodological limitations. In this study, vector-coding technique (VCT) method was proposed as a comprehensive methodology to quantify the precise transition phase and examine low back torsional load. Towards this end, transition phases were assessed using three different methods (VCT, lead hand speed and X-factor stretch) and compared; then, low back torsional load during the transition phase was examined. As a result, the importance of accurate transition phase quantification has been documented. The largest torsional loads were observed in healthy professional golfers (10.23 ± 1.69 N · kg -1 ), followed by professional golfers with a history of LBP (7.93 ± 1.79 N · kg -1 ), healthy amateur golfers (1.79 ± 1.05 N · kg -1 ) and amateur golfers with a history of LBP (0.99 ± 0.87 N · kg -1 ), which order was equal to that of the transition phase magnitudes of each group. These results indicate the relationship between the transition phase and LBP history and the dependency of the torsional load magnitude on the transition phase.

A low carbon industrial revolution? Insights and challenges from past technological and economic transformations

2012-01-01

Recent efforts to promote a transition to a low carbon economy have been influenced by suggestions that a low carbon transition offers challenges and might yield economic benefits comparable to those of the previous industrial revolutions. This paper examines these arguments and the challenges facing a low carbon transition, by drawing on recent thinking on the technological, economic and institutional factors that enabled and sustained the first (British) industrial revolution, and the role of ‘general purpose technologies’ in stimulating and sustaining this and subsequent industrial transformation processes that have contributed to significant macroeconomic gains. These revolutions involved profound, long drawn-out changes in economy, technology and society; and although their energy transitions led to long-run economic benefits, they took many decades to develop. To reap significant long-run economic benefits from a low carbon transition sooner rather than later would require systemic efforts and incentives for low carbon innovation and substitution of high-carbon technologies. We conclude that while achieving a low carbon transition may require societal changes on a scale comparable with those of previous industrial revolutions, this transition does not yet resemble previous industrial revolutions. A successful low carbon transition would, however, amount to a different kind of industrial revolution. - Highlights: ► Investigates lessons for a low carbon transition from past industrial revolutions. ► Explores the implications of ‘general purpose technologies’ and their properties. ► Examines analysis of ‘long waves’ of technological progress and diffusion. ► Draws insights for low carbon transitions and policy.
