The Impact of Skill Mismatch among Migrants on Remittance Behaviour
This paper considers the issue of skill mismatch among immigrants and its impact on their remittance behaviour using cross-sectional data from two linked surveys in the Philippines: the Survey on Overseas Filipinos (SOF) and the Family Income and Expenditure Survey (FIES) for the years 1997, 2000, and 2003. Our main hypothesis is that skills mismatch - broadly defined here as the over-qualification of migrants in terms of educational attainment relative to occupation in their destination country - is prevalent among skilled migrants and exerts a downward pressure on the level of international remittances received by the sending economies. Accordingly, a high incidence of skill mismatch implies that the remittances expatriated would be significantly less compared to conditions of no skills mismatch. We find evidence of substantial skill mismatch, particularly among highly educated women, but there is also systematic variation in the incidence of skill mismatch by family characteristics and host country. In terms of remittances, we find that for women, higher education levels are associated with lower incidence of remittances but larger amounts remitted. However, negative skill mismatch leads to men and women both being more likely to remit money, but for women the amount is significantly less than it otherwise would have been.remittances, immigrants, education mismatch
The Unloneliness of Being Alone
In this introspective photo essay composed for WRTC 103: Critical Reading and Writing, McDonald explores the role that the historic battlefields she calls home have played in forming her identity and forging her relationships with her father and family. Pairing original photographs of battlefields and landscapes with her reflections on adolescence and identity, McDonald crafts a strong sense of place, both visually and textually
The impact of long-term visitors on projections of Australia's population
In 1999 and 2000, for the first time, net long-term visitor migration exceeded net permanent migration, by nine per cent in 1999 and by 21 per cent in 2000. This report focuses on the longer-term demographic implications of this change by constructing an alternative population projection methodology
Associative and repetition priming with the repeated masked prime technique: No priming found
Wentura and Frings (2005) reported evidence of subliminal categorical priming on a lexical decision task, using a new method of visual masking in which the prime string consisted of the prime word flanked by random consonants and random letter masks alternated with the prime string on successive refresh cycles. We investigated associative and repetition priming on lexical decision, using the same method of visual masking. Three experiments failed to show any evidence of associative priming, (1) when the prime string was fixed at 10 characters (three to six flanking letters) and (2) when the number of flanking letters were reduced or absent. In all cases, prime detection was at chance level. Strong associative priming was observed with visible unmasked primes, but the addition of flanking letters restricted priming even though prime detection was still high. With repetition priming, no priming effects were found with the repeated masked technique, and prime detection was poor but just above chance levels. We conclude that with repeated masked primes, there is effective visual masking but that associative priming and repetition priming do not occur with experiment-unique prime-target pairs. Explanations for this apparent discrepancy across priming paradigms are discussed.

Impregnando la pedagogĂa centrada en el juego con una perspectiva «Constraint-Led» para la enseñanza del tenis en las escuelas
The Game Sense approach (GSA) helps sport teachers adopt a pedagogical toolkit for the complex interplay of collective decision making in tennis that evolves from the dynamics of momentary configurations of play meeting the personal coordination dynamics of the players. This pedagogical toolkit emphasises game-based play to teach players how to perceive the game as âthinking playersâ capable of functional behaviours that answer the requirements of momentary configurations of play. This paper, therefore, builds on recent theoretical debate in the areas of skill acquisition, the complementarity of perception-decision making and personal coordination dynamics (techniques), complex learning theory and coaching pedagogy, to connect the constraints-perspective of skill acquisition and the pedagogy of the Game Sense approach to enable theoretically informed tennis teaching. Practical implications of game-based training will be explained using the example of the Tennis for Primary Schools program alignment with the developmental stages of the Australian Curriculum for Health and Physical Education (ACHPE), which are described as student achievement standards in this curriculum.El enfoque centrado en el sentido del juego (GSA) proporciona a los profesores deportivos un conjunto de herramientas pedagĂłgicas para el abordaje de las complejas interacciones que tienen lugar en la toma colectiva de decisiones en el tenis, que evoluciona a partir de la confluencia dinĂĄmica entre las configuraciones momentĂĄneas del juego y la coordinaciĂłn entre los jugadores. Estas herramientas pedagĂłgicas destacan la comprensiĂłn del juego a fin de enseñar a los deportistas a percibirlo como âjugadores pensantesâ, capaces de comportamientos funcionales que respondan a los requisitos de las configuraciones momentĂĄneas del juego. Este artĂculo se basa en los recientes debates teĂłricos en las ĂĄreas que estudian la adquisiciĂłn de habilidades; la complementariedad entre los procesos de percepciĂłn, la toma de decisiones y las dinĂĄmicas de coordinaciĂłn personal; la compleja teorĂa del aprendizaje y la pedagogĂa del entrenamiento; todo ello para conectar la perspectiva de los âlimitadoresâ (contraints, ver nota 1) y la pedagogĂa del enfoque centrado en el sentido del juego, para lograr una enseñanza del tenis fundamentada teĂłricamente. Las implicaciones prĂĄcticas del entrenamiento basado en el sentido del juego se explicarĂĄn sirviĂ©ndonos del ejemplo de un programa de Tenis para la Escuelas Primaria, el cual estĂĄ en lĂnea con las etapas del desarrollo del CurrĂculo Australiano de EducaciĂłn FĂsica y Salud (ACHPE), descritas en el mismo como estĂĄndares de logro para los estudiantes
Bioaccumulation and detection of trace levels of cadmium in aquatic systems by Eichhornia crassipes
The water hyacinth (Eichhornia crassipes) may be used as a sensitive biological indicator for continuously monitoring trace quantities of toxic heavy metals in aquatic systems. A river water system polluted with cadmium was simulated while other factors of temperature, day-night cycle, water quality, and light intensity remained constant. When the water hyacinth is maintained in river water containing 0.001 mg/l. of cadmium chloride, the plant's root system will concentrate this element at an average rate of 0.9, 1.4, and 3.0 ÎŒg Cd/g root dry weight after 24, 48, and 72 hr exposure periods, respectively. At a higher cadmium concentration of 0.01 mg/l., cadmium was concentrated in the roots much faster to levels of 6.8, 13.6, and 39.1 ÎŒg/g root after 4, 8, and 24 hr exposure periods, respectively. At initial concentrations of 0.05 mg/l. cadmium, the roots contained 29.5, 48.8, and 156 ÎŒg/g root following 4, 8, and 24 hr exposure periods, respectively. During these same time intervals, the water hyacinth sorbed 56.7, 153, and 281 ÎŒg/g root when the initial cadmium concentration was increased to 0.10 mg/l. The water hyacinth tops can also assist in the monitoring process when cadmium contamination levels are 0.10 mg/l. and greater. At this initial cadmium concentration, cadmium is translocated into the tops. After 8 hr, the tops averaged 1.1 ÎŒg/g top. After 24 hr, this concentration was increased to 6.1 ÎŒg/g top
Comparisonâspecific preferences:The attentional dilution effect for delay and risk
In cross-modal decisions, the options differ on many attributes, and in uni-modal decisions, they differ on few. We supply new theory and data to understand how discounting for both delay and risk differs between cross-modal and uni-modal decisions. We propose the attentional dilution effect in decision making in which (a) allocation of limited attention to an attribute determines that attribute's decision weight and (b) the attention an attribute receives is increasing in the difference between options on that attribute and decreasing in the number of other attributes that differ between options. We introduce the random order delayed compensation method and conduct two experiments focusing on delayed and risky receipt of consumer goods. Consistent with the attentional dilution effect, we find that in this domain, patience and risk tolerance are generally higher in cross-modal than uni-modal decisions. We suggest that, since many real-world choices are cross-modal, people may be more patient and risk-tolerant in their everyday life than is suggested by standard lab experiments
Comparison of Deer Repellents Applied to Azaleas and Pansies
The effectiveness of commercially-available repellents in reducing browse by white-tailed deer (Odocoileus virginianus) was assessed on two varieties of azaleas (Rhododendron spp.)and one variety of pansies (Viola tricolor var. hortensis). Repellents examined included Plantskyddâą (liquid, granular), Deer Stopperâą, Milorganiteâą, and Repels-Allâą. Evergreen azaleas in 15-gallon containers were observed during 3 trial seasons in October âMay, 2012 â2015. During each trial, individual plants were treated with the maximum recommended level of each repellent, or no repellent, or no repellent with a wire cage to serve as a positive control. At the end of each trial, leaves were stripped from azaleas, dried and weighed to determine level of browsing. While differences (P \u3c .05) in leaf weight were evident across seasons, no differences (P \u3e.05) could be attributed to any repellent. Repellents (except Milorganiteâą) were tested on pansies from November âDecember 2018. Percentage of browsing of plants was determined by visual observation every 7 to 10 days. The control and some treated plants were browsed initially. Virtually all plants, treated or not treated, were extensively damaged by deer browsing within 40 days. Thus, no repellent was found to be100% effective at reducing deer browsing damage in this study
Context, latency and the value of preventing a statistical cancer fatality
PhD ThesisThis thesis contributes to the state of understanding about the value of latent health and
fatality risk reductions, focussing on the effects of context and latency on the Value of
Preventing a Statistical Cancer Fatality (VSLCAN) relative to road accident fatalities. The
conceptual, methodological and empirical contributions are derived from two stated
preference studies. The studies are designed to explore how the VSLCAN is driven by the
context effect, which includes dread of the cause âcancerâ and the effects of illness prior to
fatality; and the latency (delay) effect which depends upon time preferences and risk
preferences.
Study 1 develops a Risk-Risk survey protocol, and the resulting central tendency and
regression analysis verify that the context of cancer increases the VSL and that latency
decreases it. The relativity between VSLCAN and the road accident VSL is then summarised
into a simple relationship where the offsetting influences of context and latency are
parameterised. This novel tool has the potential to enhance the comparability and evaluation
of a wide range of existing and future VSL studies involving context and latency effects
through the elicitation of key underlying parameters such as the context premium and
effective discount rate. As such it represents a significant methodological contribution.
Study 2 focusses directly on two aspects of the latency effect. These relate to risk and time
preferences, explored in Studies 2a and 2b respectively. Delayed outcomes are inherently
risky, so the exploration of latent outcomes requires controlling for risk preferences. Study
2a develops a theoretical and empirical framework for eliciting risk aversion proxies in the
domain of health, which have not previously been fully developed in the literature. The
method extends the classic Holt-Laury risk preference elicitation framework into a new
domain- health risks- and the method is implemented successfully in Study 2. This chapter
therefore makes both conceptual and methodological contributions through clarifying the
utility theoretic basis of a health risk aversion measure and then developing a way to elicit
such a measure in surveys. Study 2b uses the novel VSLCAN:VSL relationship developed in
Study 1 to elicit exponential discount rates from Risk-Risk data comparing latent cancer and
road accident risks. Regression analysis performed on these rates on a sample and individual
level, provides strong evidence to suggest that a non-standard (sub-additive) discounting
model is the most descriptively accurate discounting assumption for this sample. It provides
the first evidence regarding sub-additive discounting in the domain of health and fatality risk.funding providers at the ESRC and at the
