United We Stand Divided We Fall: Maternal Social Participation and Children's Nutritional Status in Peru

In previous literature, social capital has been hypothesized as a substitute for other forms of capital, such as physical and human capital. This paper contributes to this literature, studying the association between mothers' access to social capital via participation in community organizations and their children's nutritional status at 1 and 5 years. Using the Peruvian sample of the Young Lives project, this study suggests that, where human capital is scarce, social capital might have important implications for child development. Maternal social capital is positively associated with height at 1 year old for those children whose mothers have no formal education. No significant association is found at 5 years of age.
Impact evaluation of European funds for increasing the companies’ competitivenessin the north-west region of Romania

The assumption of this research paper is that regional competitiveness is significantly influenced by the competitiveness of the companies that are active in the region’s territory. In this matter, the purpose is to analyze the impact of the European funds dedicated to increasing the competitiveness of the companies from the North-West Region of Romania. After a seven year programming period, one can ask if indeed these interventions have achieved their objectives. Have the number of jobs and the turnover of the beneficiary companies increased? If yes, have the positive results influenced the regional competitiveness? Thus, in the present research the author is trying to find an answer using the counterfactual method, to the following evaluation question: “Did the intervention have any effect? ”. In order to respond to this question, one have determined two types of groups: the treated group (containing all the companies that received funds from the North-West region) and the non-treated group (or control group that should include companies with similar characteristics, but which didn’t receive any funds). The impact is estimated by comparing the results of the treated group with those of the control group. At the beginning of the analysis, one can plan to draw some requirements that need to be met by the units from the control group.
Quasiparticle spectra in the vicinity of a d-wave vortex

We discuss the evolution of the local quasiparticle spectral density and the related tunneling conductance measurable by the scanning tunneling microscope, as a function of distance r and angle u from the vortex core in a dx22y 2 superconductor. We consider the effects of electronic disorder and of a strongly anisotropic tunneling matrix element, and show that in real materials they will likely obscure the ;1/r asymptotic tail in the zero-bias tunneling conductance expected from the straightforward semiclassical analysis. We also give a prediction for the tunneling conductance anisotropy around the vortex core and establish a connection to the structure of the tunneling matrix element. @S0163-1829~99! 11329-8#
Graphene as a Prototypical Model for Two-Dimensional Continuous Mechanics

This paper reviews a few problems where continuous-medium theory specialized to two-dimensional media provides a qualitatively correct picture of the mechanical behavior of graphene. A critical analysis of the parameters involved is given. Among other results, a simple mathematical description of a folded graphene sheet is proposed. It is also shown how the graphene–graphene adhesion interaction is related to the cleavage energy of graphite and its C 33 bulk elastic constant.
Land-cover dynamics in Southeast Asia: Contribution of object-oriented techniques for change detection

Les ecosystemes tropicaux d'Asie du Sud-Est connaissent des changements d'occupation du sol sans precedent, constituant une menace pour la forte biodiversite de cette region. Afin de suivre de tels changements, la teledetection est de plus en plus utilisee a differentes echelles spatiales. Nous etudions ici les changements d'occupation du sol sur une periode de vingt ans, a l'echelle du paysage de sept sites d'etudes localises au Cambodge, au Laos et en Thailande. Pour chaque site, des images a haute resolution spatiale des satellites SPOT ont ete acquises a trois dates entre 1987 et 2008, ainsi que des Modeles Numeriques de Surface (SPOT et SRTM DEMs). Une methode orientee-objet de detection des changements a ete appliquee a ces images pour evaluer pour chaque site d'etude i) la localisation et ii) le taux de changement d'occupation du sol. A partir des objets classifies, nous avons egalement calcule des indices paysagers synthetiques refletant la fragmentation et l'heterogeneite du paysage. Cette analyse multi-temporelle a mis en evidence la difficulte de mettre en place un processus unique de classification comprenant de nombreux indices pour des paysages contrastes. Cependant, les techniques de classification orientees objet se sont averees appropriees pour cartographier l'occupation du sol des differentes zones d'etudes, et ainsi d'en etudier les changements. Les resultats mettent en evidence differents motifs de changements d'occupation du sol, avec des taux annuels de deforestation compris entre 0,65 et 1,84 %, les changements les plus importants etant observes au Cambodge et au Laos. Par ailleurs, les indices de fragmentation revelent des disparites entre les trois pays. Les methodes, resultats et perspectives de ce travail sont discutes. (Resume d'auteur)
Profile of Major Depressive Disorder Symptoms among Patients in Tehran

Objectives: Culture may place a differential emphasis on particular emotions. The aim of this study is to find the most frequent symptoms in patients with major depressive disorder in Tehran. Method: 509 patients were recruited from 5 treatment settings. The sample was used from the project of assessing psychometric properties of CIDI in the Iranian population. The patients were evaluated by conducting clinical interviews and using DSM-IV criteria (American Psychiatric Association, 1994) for major depressive disorder. Results: Depressed mood (98.7%), sleep change (92.1%) and, fatigue / energy loss (89.4%) were the three highest-ranking symptoms. As cognitive factors, guiltiness and worthlessness were among the lowest ranking symptoms. There were no significant differences between men and women in frequency of symptoms with the exception of suicidal thoughts. Men had significantly higher suicidal thoughts than women. (P: 0. 01) Conclusion: Data were presented on the depressive symptomatology in population of Tehran. Key findings included a high rate of somatic symptoms in patients who suffered from MDD in this population.
Renormalization of Hořava gravity

We prove perturbative renormalizability of projectable Horava gravity. The key element of the argument is the choice of a gauge which ensures the correct anisotropic scaling of the propagators and their uniform falloff at large frequencies and momenta. This guarantees that the counterterms required to absorb the loop divergences are local and marginal or relevant with respect to the anisotropic scaling. Gauge invariance of the counterterms is achieved by making use of the background-covariant formalism. We also comment on the difficulties of this approach when addressing the renormalizability of the nonprojectable model.
Factors influencing medical decision- Making for seriously ill patients in the Acute Care Hospital

Aim: To acquire a fuller understanding of the influences on decision-making in an acute care hospital for seriously ill patients. Background: Fromthe moment of a diagnosis of serious, potentially life-limiting illness, patients and their families are faced withmultiple, complex and significant decisions that will influence the entire illness trajectory, including their end-of-life care (EOLC). Compounding personal factors is the complexity of dying today with acute ward areas in tertiary hospitals use of technological interventions to prolong life, at all costs being the norm. If hospice care is initiated, in these areas, it is often at too late a stage to relieve distressing symptoms and to offer the person the best possible path of care for a dignified death. Design and methods: A retrospective cohort research design was used for this study. Results: Thirty nine (39) medical records that met the inclusion criteria were audited. While medical records are limited in terms of the quality of the information contained in them in terms of social, behavioural and other qualitative information, the audit obtained detailed clinical information on patient characteristics, clinical care, and family and clinician involvement in the care of these patients. Communication between health professionals and patient and or family were limited. Poor documentation in the medical record did not support shared decision-making with decisions to amend the care pathway to palliative not undertaken in most instances despite no improvement in response to care or deterioration in the patient’s condition. Conclusion: Communication between health care professions, patients and their family’s needs to be addressed. The management of patients who are seriously ill in acute ward areas should be altered to reflect the patient’s condition. Nurses, using a person-centred approach, have a role in advocating for the patient and the family in times of stress. Discussions concerning end-oflife of seriously ill patients need to be open, transparent and communicated as these discussions are critical to ensuring the patient’s wishes are realised.
Commitment and Tenure of Highly Skilled Volunteers: Management Issues in a Nonprofit Agency

Recognizing that turnover in an agency's volunteer population is especially costly in the case of highly trained volunteers, we analyzed data from a nationwide survey of crisis and suicide intervention volunteers to identify variables contributing to volunteers' attachment to their crisis center. We measured attachment both as level of commitment during the volunteer's association with the center and the length their association at the time of the survey. Although little of the variation in commitment levels could be explained, statistically significant variables included two variables under management discretion, whether agencies urged volunteers not to disclose their.relationship to the center, and the proportion of the center's volunteer workforce comprised of students. In the regression explaining the length of volunteers' association with the center, agencies that provided opportunities for face-to~face counseling experience, reflecting diversity of tasks and the possibility of advancement, were seen to retain their volunteers longer. Other significant variables readily available to the agency when screening volunteer applicants include student status, age among the nonstudent population, and whether the volunteer was pursuing a career to which crisis skills were related.
Designing a Test Set for Structural Testing in Automatic Programming Assessment

An automatic programming assessment (APA) method aims to support marking and grading of students’ programming exercises. APA requires a test data generation to perform a dynamic testing on students’ programs. In software testing field, diverse automated methods for test data generation are proposed. Unfortunately, APA seldom adopts these methods. Merely limited studies have attempted to integrate APA and test data generation to include more useful features and to provide a precise and thorough quality of program testing coverage. Thus, we propose a test data generation approach to cover both the functional and structural testing of a program for APA by focusing the structural testing in this paper. We design a test set based on the integration of positive and negative testing criteria that enhanced path coverage criterion to select the desired test data. It supports lecturers of programming courses to furnish an adequate set of test data to assess students’ programming solutions in term of structural testing without necessarily having the expertise in a particular knowledge of test cases. The findings from the experiment depict that the test set improves the criteria of reliability and validity for test data adequacy in programming assessments.
Web Analytics for Each Stage of E-government Implementation: A Study in the Indian Context

More than twenty stage, or maturity, e-government models have been suggested in the last fifteen years, globally. The number of stages varies from model to model, but overall there is general consensus on five generic stages of e-government maturity, identified as: information; interaction; transaction; integration and one-stop portal for e-government. In India, as e-government services are being provisioned and consumed by the stakeholders including general public, a significant number of government bodies are at information, interaction and transaction stages of the generic growth model. Some government departments and ministries are gradually moving towards integration (horizontally and vertically) but none of the government organizations in India is at the full interoperable stage. The interface between the citizens and e-government services is through portals. An intuitive and easy user interface is crucial for each stage of e-government maturity so that citizens can fully utilize e-government services. Availability of the relevant technology to the general public is also imperative. It is noticeable that with the rise in online interaction and shift from Web 2.0 to Web 3.0, the use of e-government services has increased considerably. Keeping the stages of e-government growth model in mind, it is highly important that the response of the citizens and other stakeholders is measured and analysed at each level, mainly to understand the effectiveness of the provision. Therefore, web analytics at each stage of e-government is crucial. The objective of the paper is to identify the key performance indicators for each level of e-government growth and suggest relevant web analytic tools that can help in analyzing the response of citizens and to further help in improving the e-government process.
The ToF-ACSM: a portable aerosol chemical speciation monitor with TOFMS detection

Abstract. We present a new instrument for monitoring aerosol composition, the time-of-flight aerosol chemical speciation monitor (ToF-ACSM), combining precision state-of-the-art time-of-flight mass spectrometry with stability, reliability, and easy handling, which are necessities for long-term monitoring operations on the scale of months to years. Based on Aerodyne aerosol mass spectrometer (AMS) technology, the ToF-ACSM provides continuous online measurements of chemical composition and mass of non-refractory submicron aerosol particles. In contrast to the larger AMS, the compact-sized and lower-priced ToF-ACSM does not feature particle sizing, similar to the widely-used quadrupole-ACSM (Q-ACSM). Compared to the Q-ACSM, the ToF-ACSM features a better mass resolution of M/ΔM = 600 and better detection limits on the order of 10 months) on the Jungfraujoch mountain ridge (3580 m a.s.l.) in the Swiss Alps, agree quantitatively. Additionally, the mass resolution of the ToF-ACSM is sufficient for basic mass defect resolved peak fitting of the recorded spectra, providing a data stream not accessible to the Q-ACSM. This allows for quantification of certain hydrocarbon and oxygenated fragments (e.g. C3H7+ and C2H3O+, both occurring at m/Q = 43 Th), as well as improving inorganic/organic separation.
Social isolation and student voting behavior: How voting frequen­cy is affected by individual perceptions of loneliness

This paper examines the link between social connectivity and lack of participation in democratic political systems. Using a set of novel scales that examine both objective and subjective social relationships, the paper seeks to show that individual participation in elections (the act of voting) is directly connected with perceptions of loneliness. In addition to these primary scale sets, many other aggregate factors (such as gender, race and class as well as generational effects) are examined to better triangulate causation. Background Attempts to evaluate voter turnout have thus far taken one of three general forms: analysis of the individual characteristics of the voter, analysis of behavioral characteristics found across the voting population, and the systemic or structural analysis of laws and voting systems. In each of these general forms, psychological variables are used across the wide canon of work as an explanatory device for an individual's choice in voter participation. The primary focus of this exploratory study is identification of one such underused explanatory psychological variable (loneliness) and its correlation with voter turnout. The use of traditional individual characteristic independent variables (such as race, class, and gender) across studies examining turnout have
3D registration of depth data of porous surface coatings based on 3D phase correlation and the trimmed ICP algorithm

A critical factor of endoprostheses is the quality of the tribological pairing. The objective of this research project is to manufacture stochastically porous aluminum oxide surface coatings with high wear resistance and an active friction minimization. There are many experimental and computational techniques from mercury porosimetry to imaging methods for studying porous materials, however, the characterization of disordered pore networks is still a great challenge. To meet this challenge it is striven to gain a three dimensional high resolution reconstruction of the surface. In this work, the reconstruction is approached by repeatedly milling down the surface by a fixed decrement while measuring each layer using a confocal laser scanning microscope (CLSM). The so acquired depth data of the successive layers is then registered pairwise. Within this work a direct registration approach is deployed and implemented in two steps, a coarse and a fine alignment. The coarse alignment of the depth data is limited to a translational shift which occurs in horizontal direction due to placing the sample in turns under the CLSM and the milling machine and in vertical direction due to the milling process itself. The shift is determined by an approach utilizing 3D phase correlation. The fine alignment is implemented by the Trimmed Iterative Closest Point algorithm, matching the most likely common pixels roughly specified by an estimated overlap rate. With the presented two-step approach a proper 3D registration of the successive depth data of the layer is obtained.
Applicability of Quantum Dots in Biomedical Science

Quantum dots (QDs) are novel class of inorganic fluorophore with superior photophysi - cal properties. Superior optical properties are a promising alternative to organic dyes for fluorescence biomedical applications. These nanoparticles have size-tunable emission, strong light absorbance, and very high levels of brightness and photostability. Highly luminescent QDs are prepared by coating the core with another material, resulting in core-shell quantum dots that are more stable in various chemical environments. These core-shell QDs are hydrophobic and only organic soluble as prepared. Hydrophobic QDs are insoluble in aqueous solution and cannot be directly employed in biomedical applications. They are necessarily made water soluble by surface modifying them with various bifunctional surface ligands or caps to promote aqueous solubility and enhanc ing biocompatibility. To make them useful for biomedical applications, QDs need to be conjugated to biological molecules without disturbing the biological function of these molecules. Most of the current studies were designed to ask questions concerning the physicochemical properties of novel QD products, not QD toxicity per se . The poten tial toxicity of the QDs is a cause for concern because they are made of heavy metals. The limitation of heavy metal–containing QDs stimulates extensive research interests in exploring alternative strategies for the design of fluorescent nanocrystals with high biocompatibility.
Lead Zirconate Titanate Thick-Film Ultrasonic Transducer for 1 to 20 MHz Frequency Bands Fabricated by Hydrothermal Polycrystal Growth

A thickness vibration mode ultrasonic transducer was fabricated by hydrothermal deposition of lead zirconate titanate polycrystalline thick film. This hydrothermal polycrystalline PZT thick-film (HPTF-PZT) ultrasonic transducer was studied for its wide-frequency-band transmission characteristics. The transducer had a 50-µm-thick PZT layer on a 50-µm-thick titanium substrate in an active area of 8 mm×8 mm. The experimental results showed the HPTF-PZT ultrasonic transducer radiated a single ultrasound pulse in the frequency range from 1 to 20 MHz with a 20 dB deviation. Additionally, this transducer generated a 2 MHz sawtooth ultrasonic wave with odd-and even order-harmonic components from the 2nd to the 11th harmonics. These results indicate that the fabricated ultrasonic transducer has satisfactory wide-band characteristics for a MHz frequency range ultrasonic transmitter.
Blogs and the Economics of Reciprocal Attention

Blogs differ from other media in that authors are usually not remunerated and inscribe themselves in communities of similarly minded individuals. Bloggers value reciprocal attention, interaction with other bloggers and information from reading other blogs; they value being read but also writing itself, irrespective of an audience. A novel dataset from a major blogging community, LiveJournal, is used to verify predictions from a model of social networking. Content production and blogging activity are found to be related to the size and degree of asymmetry of the relational networks in which bloggers are inscribed.
Support Staff and Intellectual Capital: Evidence From the University Of Otago

Intellectual capital is quickly becoming a source of competitive advantage. Therefore, it is important to ensure intellectual capital, consisting of human capital, structural capital, and relational capital, is being created and managed in an efficient way. Previous studies have demonstrated that the interaction between the three forms of capital significantly increase intellectual capital in private sector organisations. This study focuses on what has been argued as the largest producers of intellectual capital, higher education institutions; more specifically this study focuses on the University of Otago. The aim of this study is to determine whether ancillary support staff assist in the creation of intellectual capital at the University of Otago. As the University of Otago is a public organisation, it is important to ensure intellectual capital is managed efficiently to improve organisational performance.
Direct Somatic Embryogenesis Induction through Modification of BAP and IAA on Tobacco ( Nicotiana tabacum L ) Variety H-382 Putri

Somatic embryogenesis is one way of in vitro propagation of tobacco to produce the homogenous plant. This research used ZPT, BAP, IAA and the propagation combination of tobacco (Nicotiana tabaccum L.) of variety H-382 through somatic embryogenesis. The research aimed to determine the concentrations of IAA, BAA and their optimum combination for tobacco propagation. The research was conducted at Plant Tissue Culture Laboratory, Agronomy Department, Faculty of Agriculture, University of Jember, from January 1th to June 30th , 2015. The research applied Factorial Completely Randomized Design with 2 factors. The first factor was BAP concentration (B) consisting of 4 levels i.e. B0 (control 0 ppm BAP ), B1 (2.0 ppm BAP ), B2 (2.5 ppm BAP ), B3 (3.0 ppm BAP ). The second factor was IAA (I) which consisted of 4 levels i.e. I0 (control 0 ppm IAA) , I1 (0.1 ppm IAA), I2 (0.2 ppm IAA), I3 (0.3 ppm IAA). The results showed that the combination of treatments between BAP 3.0 ppm and IAA 0.2 ppm (B3I2) was the best treatment somatic embryogenesis induction and number of shoots and root length.
