Domestic service, migration and the social status of women at marriage: the case of a Dutch Sea Province, Zeeland 1820-1935

Some scholars have seen female domestic service as a 'bridging occupation', facilitating the migration of women from the countryside to the cities and enabling them to make advantageous marriages and become upwardly socially mobile. However, previous research has yielded contradictory results with regard to the marriages of female servants. On the basis of 1800 marriage records, in this article it has been estimated how social background, occupation and migration determined the status at marriage of women in the province of Zeeland the Netherlands, in the period 1820-1935. When holding everything equal, just exercising the occupation of domestic service didn't result in marriages with men of higher social positions as could be expected given the status of the job. However, living in a city by the time of one's marriage, did indeed offer women greater chances on a high status marriage.
The Variability of Fatigue in Notched Bars of IN100 (Preprint)

Abstract : IN100 is one of the workhorse nickel-base superalloys of the current fleet of turbine engines owned and operated by the US Air Force. Many of the life-limited locations on fracture critical IN100 components are associated with locations of stress concentrations, e.g. bolt holes, fillets, balance flange scallops, etc. The prior work by Jha, Caton, and others examining the fatigue variability of nickel-base superalloys found a link between the minimum fatigue life and fracture mechanics. This prior work only examined the fatigue behavior of smooth fatigue bars. The current effort determined that the link between minimum fatigue life and fracture mechanics is applicable even when only a small volume of the material at the root of a notch is subject to the high stress conditions.
Trochanteric Buttress Plate Combined with Proximal Femoral Nail for Unstable Intertrochanteric Fractures. [Innovative Technique]

Introduction: Proximal femoral nail is a better choice of implant for the treatment of an unstable trochanteric fracture, however it is associated with screw migration and cutout because of greater trochanteric comminution and coronal split. This study is to evaluate the results of Trochanteric Buttress Plate (TBP) combined with PFN in an unstable IT fractures for buttressing lateral wall and reinforcing fixation. Materials and Methods: We carried out a consecutive study of 32 patients of Unstable intertrochanteric fracture femur with lateral wall comminution. It was studied at Ashwini Sahakari Rugnalaya and Sanshodhan Kendra Solapur India and Government medical college Chandrapur India from April-2015 to December-2017 using innovative Trochanteric buttress plate along with PFN. Eighteen male and fourteen female in the age group of 55 to 80 years were included in the study. There were 26 cases of A3 and six cases of A2 were fixed by PFN combined with trochanteric buttress plate to augment the comminuted lateral wall. Results: The bone healing is observed in all the cases in the mean period of 12.6 weeks. Four patients developed complications, including lateral migration of neck screws (n = 2), superficial infection (n = 2). Patients were followed up for a mean of 10.6 months. At the end of follow-up the Salvati and Wilson hip function was 36 (out of 40) in 87.5% of patients [twenty eight patients]. The clinical, radiological and functional outcomes were found to be satisfactory. Conclusion: The stabilization of lateral trochanteric wall with trochanteric buttress plate restores anatomy, increases the stability of construct and prevents inherent complication of screw migration and cutout.
Title Optimal Monetary Policy in a Currency Union with Interest RateSpreads

We study optimal monetary policy in a two-country currency union model with nominal and financial frictions. In addition to, and independent from, the standard transmission mechanism associated with sticky prices, financial frictions combined with asymmetric asset positions introduce a wealth redistribution role for monetary policy in our model. Financial frictions also lead to a spread between the deposit and borrowing interest rate and variation in the spread affects both aggregate variables, by affecting total spending, and relative (cross-country) variables, by redistributing wealth across countries. Moreover, the interactions between nominal and financial frictions amplify the effects of monetary policy; imply that a strict inflation targeting policy of setting union-wide inflation to zero is never optimal and that optimal policy never attains effi ciency; and lead to a novel policy trade-off for the central bank in stabilizing relative consumption versus the relative price gap (the deviation of relative prices from their effi cient level). Finally, under optimal monetary policy, in response to an aggregate purely financial shock that causes an increase in the interest rate spread, the central bank strongly decreases the deposit rate, which reduces aggregate and distributional ineffi ciencies by mitigating the drop in output and inflation and the rise in relative consumption and prices. We also show that while a traditional Taylor rule approximates optimal policy imperfectly, especially in response to the financial shock, a spreadadjusted Taylor rule performs better as it helps the real interest rate track the effi cient rate of interest.

Review of synthesis and antioxidant potential of fullerenol nanoparticles

This review describes the chemical synthesis of polar polyhydroxylated fullerene C60 derivatives, fullerenols C60(OH)n, 2 ≤ n ≤ 44, C60HzOx(OH)y, and polyanion fullerenols C60(OH)15(ONa)9, ranging from the very first synthetic methods up to some contemporary approaches to synthesis and separation. It also provides some basic information about physical characteristics of fullerenols. With the increasing number of hydroxyl groups, water solubility of fullerenols increases as well. Fullerenols both in water and biological media build nanoparticles of different dimensions and stability. In different chemical and biological model systems a large number of various polyhydroxylated fullerene derivatives were tested and they showed both their antioxidative and prooxidative characteristics. Several mechanisms have been proposed for the antioxidant activity of fullerenol. In addition, this paper also provides insight into patents referring to the antioxidant properties of fullerenol.
OWNERSHIP CONCENTRATION, FREE CASH FLOW AGENCY PROBLEM AND FUTURE FIRM PERFORMANCE: NEW ZEALAND EVIDENCE

This study seeks to empirically examine the effect of ownership concentration on mitigating free cash flow agency problem in New Zealand. Following Jensen’s (1986) argument that managers have incentives to misuse free cash flows, this study tests whether concentrated ownership structure helps alleviate such a problem or exacerbates it. A natural consequence of this agency problem will be overinvestment and other operational inefficiencies which are likely to have a detrimental impact on firms’ future performance. The second objective of this paper is to examine the association between FCFAP conditional on ownership concentration on future firm performance. We measure free cash flow agency problem as the product of positive free cash flows and growth opportunities proxied by Tobin’s Q and find that financial institution-controlled ownership structure in New Zealand is positively associated with free cash flow agency problem. We also document that free cash flow agency problem conditional on ownership concentration negatively affects future firm performance.

A Tale of Two Tasks: Comparing Steady-state Visually Evoked Potentials with the Dot Probe as Measures of the Anxiety-Related Threat Bias

Research suggests that individuals with anxiety display a threat bias (TB), or preferential attention towards threatening information. Many prior studies have utilized the dot probe, a response-time (RT) based measure of TB. The dot probe, however, has had poor internal consistency and test-retest reliability. Therefore, it is important to explore additional measures of TB. The present study compared two measures of biased attention to threat: TB measured via the dot probe and steady-state visually evoked potentials (ssVEPs), as a continuous measure of visuocortical engagement. ssVEPs entrain the frequency rate of the stimulus an individual is visually attending to. We explored how the anxiety-related TB measured by the dot probe is associated with ssVEPs, and tested the hypothesis that ssVEPs could account for greater variance in anxiety symptoms than the dot probe. Bivariate correlations were run to examine how TB scores on the dot probe were associated with ssVEP difference scores. Hierarchical regressions were conducted to examine if ssVEP difference scores could account for greater variance in anxiety than dot probe TB scores. Forty-four adults (29 females) with moderate self-reported anxiety completed the traditional dot probe, which included angry and neutral faces as cues, and a modified version of the task featuring angry and neutral faces flickering at different frequencies during which EEG was continuously recorded in order to generate ssVEPs. Results showed that TB measured via the dot probe and ssVEP amplitudes were not significantly correlated, suggesting that the dot probe and ssVEPs may index distinct components of attention to threat. In addition, counter to hypotheses, ssVEPs were not able to better account for variance in anxiety than the dot probe. The implications of these findings and future directions for investigating how attention to threat is dysregulated in individuals with anxiety are discussed.

Novel cyclic AMP signalling avenues in learning and memory

A-kinase anchoring proteins (AKAPs) form large macromolecular signaling complexes that specifically target cAMP-dependent protein kinase (PKA) to unique subcellular compartments and thus, provide high specificity to PKA signaling. For example, the AKAP79/150 family tethers PKA, PKC and PP2B to neuronal membranes and postsynaptic densities and plays an important role in synaptic function. Several studies suggested that AKAP79/150 anchored PKA contributes to mechanisms associated with synaptic plasticity and memory processes, but the precise role of AKAPs in these processes is still unknown. In this study we established the mouse brain distribution of AKAP150 using two wellcharacterized AKAP150 antibodies. Using Western blotting and immunohistochemistry we showed that AKAP150 is widely distributed throughout the mouse brain. The highest AKAP150 expression levels were observed in striatum, cerebral cortex and several other forebrain regions (e.g. olfactory tubercle), relatively high expression was found in hippocampus and olfactory bulb and low/no expression in cerebellum, hypothalamus, thalamus and brain stem. Although there were some minor differences in mouse AKAP150 brain distribution compared to the distribution in rat brain, our data suggested that rodents have a characteristic AKAP150 brain distribution pattern. In general we observed that AKAP150 is strongly expressed in mouse brain regions involved in learning and memory. These data support its suggested role in synaptic plasticity and memory processes.
A cognitive neuroscience perspective on learning and memory in aging

Learning is intrinsically related to forming long lasting memories. The last decades have seen an explosion in research related to how memories are formed, how they are processed and what their underlying neural substrates are. One of the most noticeable changes associated with aging is a decline in learning and memory abilities. Although there is now a wealth of publications in this area of research, it is nevertheless surprising how much is still unknown about the processes of high level learning in the elderly from a neuroscience perspective. This paper summarizes research from predominantly cognitive neuroscience that focuses on the relation between neural substrates and learning and memory in the healthy elderly (roughly as of 50 years of age). In this context, particular emphasis will be given to research on foreign language learning. Lernen ist unabdingbar mit der Bildung bleibender Erinnerungen verbunden. Die letzten Jahrzehnte haben einen explosionsartigen Anstieg von Publikationen in der Lernund Gedachtnisforschung erfahren, vor allem hinsichtlich der Bildung, Verarbeitung und Speicherung von Gedachtnisinhalten sowie den zugrundeliegenden neuronalen Substraten. Zu den auffalligsten Veranderungen im Alter gehort ein Leistungsabfall hinsichtlich bestimmter Aspekte des Lernens und des Erinnerungsvermogens. Umso erstaunlicher ist es daher, dass trotz der Fulle der Arbeiten im Bereich der Lernund Gedachtnisforschung kaum neurowissenschaftliche Untersuchungen uber komplexe Formen des Lernens bei gesunden alteren Menschen existieren. Der vorliegende Beitrag gibt einen Uberblick uber Forschungsergebnisse der kognitiven Neurowissenschaften mit besonderem Fokus auf die Beziehung zwischen neuronalen Substraten und Lernen und Gedachtnis bei gesunden alteren Menschen. Dabei wird der Forschung zum Fremdsprachenerwerb besondere Aufmerksamkeit gewidmet.

Grassroots Perception and Participation in Community Development Programs in Etche Local Government Area

The Study examined Grassroots Perception and Participation in Community Development Programs in Etche Local Government Area of Rivers State. The population for the study comprised 600 executive members of the community administration institutions – Town Union, Women Association, Youth Association, CDC and the Traditional Rulers Council in the thirty communities that make up the LGA spread in five clans. A multi-stage sample procedure was adopted, involving the random sampling technique which was used in selecting 2 communities from each of the 5 clans in the LGA. The second stage involved a purposive sampling of the Chairmen, Secretaries, Public Relation Officers and Treasurers of the community administration institutions – Town Union, Women Association, Youth Association, CDC and the Traditional Rulers Council. This was used to realize a sample size of 200. Questionnaire and Focus Group Discussion were adopted as instruments for data collection. The reliability coefficient is 0.87. Three research questions were posed. They were analyzed with frequencies and weighted means. The study revealed that the grassroots have a negative perception of what constitutes CD and the objectives of its programs. It also revealed that grassroots participation in CD activities has been very low. Based on the findings, the researcher recommended amongst others the need to engage qualified adult educators and community development workers in our rural communities so as to demands of creating the desired awareness to change the peoples’ perception of development and CD. Community members should be carried along at all levels of CD projects and programs – planning, implementation, monitoring and evaluation; and these programs should be co-coordinated by competent CD officers.
Belief in a Just World and Judgment in Moral Dilemmas

This paper addresses the influence of belief in a just world on moral judgment using moral dilemmas by observing the interactions with the following independent variables: 1) dual-process cognitions (automatic or deliberate), 2) the protagonist’s fate (bad, good, or absent), and 3) the type of dilemma (life-threatening or not). The results found no effects of belief in a just world on moral judgments. But an interaction between the protagonist’s fate and the dilemma type emerged as significant. In Study 1, the protagonist was identified as a victim, the participants accepted moral violations against the bad fate victim to a greater extent in the life-threatening situation (turning the car to crash into one man in order to save five men) than in the non-life-threatening situation (choosing an employee for dismissal to save the company’s financial status). In Study 2, the protagonist was specified as an offender. The participants accepted the violations against the good fate offender to a greater extent in the non-life-threatening than in the life-threatening situation. Meanwhile, the participants in the control groups (for whom the protagonist was not affected by fate) of both studies exhibited greater acceptance of moral violations in the non-life-threatening than the life-threatening situations.
Empirical investigation of stock index futures market efficiency: the case of the Athens Derivatives Exchange

Pricing and trading practices in the Athens Derivatives Exchange, a newly established derivatives market, result in significant futures arbitrage profit opportunities for low-cost traders. We find that a large part of the mispricing is due to transaction costs, but additional factors, such as anticipated volatility and time to maturity, also contribute. Ex ante tests reveal significant arbitrage opportunities that could have been exploited up to 30 min after they had been identified. All different tests employed indicate that the derivatives market was inefficient during its early trading history because arbitrage opportunities persisted even after other market impact costs were taken into consideration.
AN INVESTIGATION OF FACTORS INFLUENCING CONSUMERS' INTENTION TO USE ONLINE SHOPPING: AN EMPIRICAL STUDY IN SOUTH OF JORDAN

This study is concerned with investigation of factors that influence consumers' intention to use Online Shopping: An empirical study in South of Jordan. To achieve this aim the researcher investigated set of factors: Technology Acceptance Model (TAM) by Davis [1] was adopted in this study, which consists of two independent variables: perceived Ease of use (PEOU), perceived usefulness (PU). Also Theory of Reason Action (TRA) by Fishbein et al. [2] was adopted by using Subjective Norms (SN). In addition a mediating variable (Attitude) and dependent variable intention also adopted from both theories (TAM &TRA). Finally, Perceived Risk (PR) and Product Involvement (PI) were examined too. A questionnaire was developed and distributed to a sample of (300) respondents to collect primary data, and based on a convenience sample the response rate was about 83%. The study conducted in the context. Furthermore, the findings were analyzed using the Statistical Package for Social Software (SPSS) and Amos program to analyze the path of the independent variables. The results indicated that product involvement have the most significant positive direct impact on consumer attitudes towards online shopping and also have significant positive indirect impact on intention through attitude. Meanwhile PEOU, PU and PR have no direct impact on consumers' attitude, but have indirect impact on intention through attitude. In other hand, the result indicated that SN has positive direct impact on consumers' intention. Finally, the result indicated that consumers attitude have direct impact on consumer intention to use online shopping. Based on the research findings and conclusions, a number of recommendations and future research suggested.
Islamic banking capital challenges to increase business expansion (Indonesia cases)

In the case of Indonesia regarding capital sources in Islamic Banks, all Islamic Banks are subsidiaries of Conventional Banks (except Bank Muamalat). Bank Syariah Mandiri which is the only Islamic Bank that meets capital ownership with Business Category Bank Level III (BUKU III) is also a subsidiary of Bank Mandiri (conventional bank). In the same way, conventional banks become essential to meet the capital requirement to improve the business of Islamic Bank. This article aims to determine the role of capital and operating profit for business expansion (financing) in Bank Syariah Mandiri. The method used is the quantitative method by using statistical tool STATA version 13. The result of regression test is known that capital and profit have a significant influence in increasing financing expansion in Islamic Bank. Also, the price of the number of bad debts causes the lack of public confidence in the Islamic bank. The alternative to increasing the capital and public trust is government policies to support Islamic bank become independent.
Measurement of some engineering properties of sandbox seeds ( Hura crepitans )

The physical properties of kernels, grains and seeds are necessary for the design of equipment to handle, transport, process and store the crops. The physical properties of Hura crepitans seed have been evaluated as a function of moisture contents from 9.3 to 52.4% (wb). In the moisture range considered, seed length, width, thickness, one thousand weight and geometric mean diameter increased linearly from 20.4 to 22.8mm,21.1 to 23.0mm, 5.0 to 6.9mm ,860 to 1600g and 12.89 to 15.39mm respectively. The volume, sphericity, and surface area also increased from 758.38 to 1098.91mm 3 , 0.63 to 0.69 and 522.55 to 744.09mm 2 respectively, whiles the bulk density and the true density are 0.55 and 13.40g/mm 3 respectively. It was observed that material surface is the most determinant of the magnitude of the coefficient of static friction. The coefficient of friction was highest on plywood with 0.37 for seeds and 0.66 for kernel while the lowest coefficient of friction was recorded on stainless steel, 0.32 and 0.43 for seeds and kernels respectively. For all surfaces the kernels recorded the highest coefficient of friction. Also, the kernel angle of repose was 26.2 0 which are higher than angle of repose recorded for seeds, 19.2 0 . The results of the experiment will contribute immensely to the existing knowledge aimed at solving the problems of equipments design to handle the processing of seeds.
Intrinsic Motivation Predicting Performance Satisfaction in Athletes: Further Psychometric Evaluations of the Sport Motivation Scale-6

The study investigated psychometric properties of the Sport Motivation Scale-6 (SMS-6), assessing intrinsic regulation, four extrinsic regulation constructs, and amotivation among athletes competing at a regional and national level. In particular, we tested the factorial structure of SMS-6, its short-term stability, and the associations of SMS-6 constructs with self-efficacy, self-esteem, motivational climate, and satisfaction with sport performance. Participants were 197 athletes (57.4% women), representing team (54.7%) and individual disciplines. The measurement was repeated at the three-week follow-up (n = 107). Results yielded support for the six first-order factor structure (three second-order factors). More autonomous forms of motivation were related to higher levels of self-efficacy, performance satisfaction, and taskoriented motivational climate in sport organizations. Sequential multiple mediation analysis showed that the association between general self-efficacy and performance satisfaction at a follow-up was mediated by introjected regulation and personal-barrier self-efficacy.
