Household Willingness to Pay for Improved Solid Waste Management in Akinyele Local Government Area

Solid waste management is important in our society because it has direct effect on households’ health and society at large and the dangers that are associated with dirty environment are very serious. Solid waste problem is perhaps the most important environmental difficulty being faced with in Ibadan area, both from the generation and management points of view. Therefore, the study examines household willingness to pay for improved solid waste management in Akinyele Local Government Area. Data were collected from random selection of one hundred and twenty households with the aid of a well structured questionnaire. These data were analyzed using descriptive statistics and logit regression model.The study revealed that the average age of household heads in the study is 38.7 years and that 59.2 percent and 40.8 percent of the household respondents were female and male respectively. 51.7 percent were engaged in monthly paid job while the rest 48.3 percent were engaged in informal employment like artisan, trading and other daily earning jobs. The mean household size is 4.64. 53.3 percent of the respondents have tertiary education, 20 percent have secondary education, and 13.3 percent have primary education while only 5.8 percent have no formal education.Four methods of household’s solid waste collection with different price levels were used to determine households’ willingness to pay in the study area; these are; low cost system – N 500 (Communal container), low cost system – N 700 (Vehicle in the neighborhood), medium cost system – N 900 (Communal container with a door to door collection), higher cost system – N 1000 (Only door to door collection). The mean willingness to pay of households for the improved service is N 686.07. The multivariate binary logistic regression revealed that the households’ willingness to pay was increased as price of the service decreased, reduced as age of the respondents increased, increased as level of education increased and reduced as household size increased.It was recommended that households should thereby attach a great value to their environment and demand and pay for whatever improved service introduced to them that will make their environment clean because environmental quality will greatly influence their general wellbeing and benefit them.

Ipo Behavior in Gcc Countries: Goody-Two Shoes or Bad-to-The-Bone?

This paper documents the phenomenon of underpricing initial public offerings (IPOs) for 47 firms that went public between 2001 and 2006 in the equity markets of the six Gulf Cooperation Council (GCC) countries. The average initial abnormal returns of 290 percent exceed those found in the existing literature for both developed and emerging markets IPOs. Although the IPOs' returns over the one-year horizon beat the market index benchmark, they present negative abnormal returns once initial returns are excluded, which is consistent with findings in other industrial and emerging markets. The empirical models reject the hypothesis that the IPOs' performance is driven by the common independent variables employed in the literature. On the contrary, in the case of the GCC, country- and industry-specific characteristics, in addition to the timing of the offers, play key roles in explaining the abnormal returns of IPOs. This paper's empirical findings support the hypothesis that investors initially tend to be over-optimistic about the performance of IPOs, but grow more pessimistic over time.
Household Balance Sheets, Consumption, and the Economic Slump*

We investigate the consumption consequences of the 2006--9 housing collapse using the highly unequal geographic distribution of wealth losses across the United States. We estimate a large elasticity of consumption with respect to housing net worth of 0.6 to 0.8, which soundly rejects the hypothesis of full consumption risk-sharing. The average marginal propensity to consume (MPC) out of housing wealth is 5--7 cents with substantial heterogeneity across ZIP codes. ZIP codes with poorer and more levered households have a significantly higher MPC out of housing wealth. In line with the MPC result, ZIP codes experiencing larger wealth losses, particularly those with poorer and more levered households, experience a larger reduction in credit limits, refinancing likelihood, and credit scores. Our findings highlight the role of debt and the geographic distribution of wealth shocks in explaining the large and unequal decline in consumption from 2006 to 2009. JEL Codes: E21, E32, E44, E60.

Predicting Returns with a Co-Fractional VAR Model

We use co-fractional models to evaluate the predictive relations between returns and a valuation ratio. The co-fractional model can handle situations where financial returns are predicted using persistent valuation ratios, like dividend to price. For our application we consider very long time series, covering 355 years of real-estate returns and rent to price ratios. We find robust evidence of a fractional root of d=0.75 in the rent to price ratio. The co-fractional model empirically outperforms the traditional triangular time-series model of return predictability. For annual data, the difference in predictive R-squared is about 8%. We conclude that the co-fractional VAR provides an alternative parsimonious model for the interaction between returns and valuation ratios. The long-memory properties of the fractional model have important implications for the fi t of present-value models and the term structure of risk.
An analysis of the short term outcomes of laparotomy among surgeons in Mulago Hospital using POSSUM scoring system

th post-operative day. Day-care surgeries, patients who died on table before induction of anesthesia, and patients below 13 years of age were excluded from the study. Informed consent and assent was obtained from each patient before surgery and ethical approval was obtained from the research and review committee of Makerere University Medical School. There were 51 emergencies (67.1%) and 25 (32.9%) electives. 13 patients (17.1%) were operated by consultants, 8 (10.5%) by registrars and 55 (72.4%) by senior residents. Short-term outcome (morbidity) among the surgeons was: consultants (t= -0.081, p=0.243), registrars (t= -0.039, p=0.368), and senior residents (t= -0.041, p=0.362). Mortality outcomes for surgeons were consultants (t= -0.012, p=0.460), registrar (t=.-0.012, p=0.460) and senior residents (t= 0.087, p=0.228). POSSUM successfully analyzed the short-term outcomes of laparotomy among surgeons in MNRH. All the surgeons were performing well within the predictive power of Possum.
College Party Culture and Sexual Assault

This paper considers the degree to which events that intensify partying increase sexual assault. Estimates are based on panel data from campus and local law-enforcement agencies and an identification strategy that exploits plausibly random variation in the timing of Division 1 football games. The estimates indicate that these events increase daily reports of rape with 17-24 year old victims by 28 percent. The effects are driven largely by 17-24 year old offenders and by offenders unknown to the victim, but we also find significant effects on incidents involving offenders of other ages and on incidents involving offenders known to the victim.
Effect of Petroleum Products on Soil Catalase and Dehydrogenase Activities

The effect of refined petroleum products on the activities of selected enzymes (catalase and dehydrogenase) was studied. There was a significant decrease (p kerosene > diesel > engine oil. However, a significant increase (p diesel > petrol > engine oil. On the whole the results reveal that refined petroleum products alter soil biochemistry.
The faint radio sky: VLBA observations of the COSMOS field

We study the faint radio population using wide-field very long baseline interferometry (VLBI) observations of 2865 known radio sources in the Cosmic Evolution Survey (COSMOS) field. The main objective of the project was to determine where active galactic nuclei (AGN) are present. The combination of number of sources, sensitivity, angular resolution and area covered by this project are unprecedented. We have detected 468 radio sources, expected to be AGNs, with the Very Long Baseline Array (VLBA) at 1.4 GHz. This is, to date, the largest sample assembled of VLBI detected sources in the sub-mJy regime. The input sample was taken from previous observations with the Very Large Array (VLA). We present the catalogue with additional multiwavelength information. We find a detection fraction of 20%, considering only those sources from the input catalogue which were in principle detectable with the VLBA (2361). As a function of redshift, we see no evolution of the detection fraction over the redshift range 0.5 1.5 we find that spiral galaxies become the most prevalent (48%). We demonstrate that wide-field VLBI observations, together with new calibration methods such as multi-source self-calibration and mosaicing, result in information which is difficult or impossible to obtain otherwise.
Assortative interactions and leadership in a free-ranging population of juvenile lemon shark Negaprion brevirostris

For marine predators there is a paucity of studies on social behaviour, and even fewer studies have quantified interactions between individuals. In the present study, we looked at the social structure and leadership of free-ranging juvenile lemon shark Negaprion brevirostris in a known aggregation site, Bimini, the Bahamas. Observations of these sharks were made from towers placed in a mangrove inlet, where clear, shallow, protected waters made it possible to record group compo- sitions of externally colour-code tagged wild juvenile lemon sharks. Thirty-eight different individual sharks were observed to use the area over a 2 yr period. Results show repeated social interactions suggestive of active partner preference. In addition, we found that group structure was mostly explained by body length, and possibly by preference for relatives but not by sex. Finally, we observed that some sharks led more groups than others and that those lead individuals were usually larger than those following them. This study quantifies the social structure of a free-ranging shark population and provides novel insights into the social behaviour of juvenile sharks.
WKB solutions of difference equations and reconstruction by the topological recursion

The purpose of this article is to analyze the connection between Eynard–Orantin topological recursion and formal WKB solutions of a ħ-difference equation: Ψ(x+ħ)=(eħddx)Ψ(x)=L(x;ħ)Ψ(x) with L(x;ħ)∈GL2((C(x))[ħ]). In particular, we extend the notion of determinantal formulas and topological type property proposed for formal WKB solutions of ħ-differential systems to this setting. We apply our results to a specific ħ-difference system associated to the quantum curve of the Gromov–Witten invariants of P1 for which we are able to prove that the correlation functions are reconstructed from the Eynard–Orantin differentials computed from the topological recursion applied to the spectral curve y=cosh−1⁡x2. Finally, identifying the large x expansion of the correlation functions, proves a recent conjecture made by Dubrovin and Yang regarding a new generating series for Gromov–Witten invariants of P1.

A Low-Power High-Gain Low Noise Amplifier For Wake-Up Receivers

The recent researches are focus on the ultra-low power system like bio-medical device and IoT/IoE devices. In this case, the Wake-Up Receiver (WuRx) is absolutely necessary to make connections between devices with ultra-low power consumption. In the WuRx, the most important block is the Low-Noise Amplifier (LNA). The purpose of LNA in the WuRx is to ensure an accurate communication and reduce overall system power consumption between devices by performing several roles simultaneously on single stage like high gain and low noise and so on. This thesis presents the design of LNA for input stage of WuRx. For low power WuRx architecture, the differential output of tunable high gain, low noise figure, input/output isolation, differential output gain-phase balancing, good linearity, and low power are needed simultaneously. The pseudo-differential LNA incorporates an active single-to-differential conversion. By utilizing Qenhancement circuit with LC tank at output nodes of pseudo-differential topology, the LNA has a tunable ultrahigh gain. And, the both input/output isolation and differential output gain-phase balancing can be achieved by using capacitive cross-coupled technique. We described the bootstrapping capacitor for noise filtering effect in the pseudo-input stage. A 2.4GHz LNA design optimized in a 90nm CMOS process shows that the tolerable differential output gain-phase imbalances are up to 0.08dB and 0.1°, respectively. And, the simulation results show that proposed LNA achieves a noise figure of 4.7 to 5.7dB, and an IIP3 of -26.9dBm to -63.5dBm at the 2.4GHz according to the tunable current of Q-enhancement for obtaining variable gain of 26dB to 56dB with just 90 to 169μA current consumption, and 1V supply voltage.
Acquiring clitics and determiners in child L2 Modern Greek

The present paper explores the acquisition of third person direct object clitics and definite determiners by Turkish-speaking child L2 learners of Modern Greek. 66 Turkish-speaking children aged 7-12 and of five different proficiency levels were administered three tasks, in order to test the production of object clitics and the definite determiner. Furthermore, the production of phi-features and case was controlled for. Preliminary results show an initial omission of the two D-elements, but a later differentiation in their acquisition pattern, as clitic drop remains robust until later stages of acquisition. At the same time a hierarchical acquisition pattern of uninterpretable features is found (case, number>gender).

STRATEGIC ALLIANCE AND COMPETITIVE ADVANTAGE – AN EXPLORATORY STUDY IN BRAZILIAN FIRMS

This work discusses the characteristics of strategic alliances that affect the obtainment of competitive advantages, according to the perception of managers who responded to the following question: can strategic alliances contribute to the obtainment of competitive advantages? It also demonstrates to companies of this type that do not participate in cooperative arrangements the benefits that they might receive from this relationship. This exploratory work was developed through a field survey based on the administration of a questionnaire to Information Technology companies. The questionnaire was constructed with two scales, one on competitive advantages and the other on strategic alliances. The survey was answered by 121 companies of various sizes, located in various Brazilian states. The data were analyzed through canonical correlation and the results showed that organization, commitment, focus on mutual gains and cooperation are the elements that favor competitive advantages, especially related to the enhancement of operational efficiency, enhancement of response power through agility and flexibility, pioneering potential, innovation and managerial capacity. Keywords: Strategic Alliances – Brazilian States – IT.

The Financial/Economic Dichotomy in Social Behavioral Dynamics: The Socionomic Perspective

Neoclassical economics does not offer a useful model of finance, because economic and financial behavior have different motivational dynamics. The law of supply and demandoperates among rational valuers to produce equilibrium in the marketplace for utilitarian goods and services. The efficient market hypothesis (EMH) is a related model applied to financial markets. The socionomic theory of finance (STF) posits that contextual differences between economics and finance produce different behavior, so that in finance the law of supply and demand is irrelevant, and EMH is inappropriate. In finance, uncertainty about valuations by other homogeneous agents induces unconscious, non-rational herding, which follows endogenously regulated fluctuations in social mood, which in turn determine financial fluctuations. This dynamic produces non-mean-reverting dynamism in financial markets, not equilibrium.
Influence of solar flare's location and heliospheric current sheet on the associated shock's arrival at Earth

We study the source locations of 130 solar flare-type II radio burst events with the associated interplanetary shocks observed by L1 spacecraft (type A events) and 217 flare-type II events without such shocks observed at L1 (type B events) during February 1997-August 2002. In particular, we investigate the relative positions between the flare sources, the heliospheric current sheet (HCS), and the Earth. We found the following results: (1) Solar flares are usually distributed within [S30 degrees, N30 degrees] in heliographic latitude and [S30 degrees, N30 degrees] x [E10 degrees, W30 degrees] is the predominant source region on the solar disk that includes the majority of geoeffective solar flares. (2) The shocks with the associated flares located near the HCS would have a lower probably of reaching the Earth. For the Earth-encountered shocks, their initial speeds are distinctly higher when their associated flares are located near the HCS. (3) The angular distance from the flare source to the Earth (defined as Psi below) also contributes to the probability of the associated shock being observed at the Earth. The shock arrival probability decreases with the increment of Y and the mean initial shock speed increases with Y for those Earth-encountered shocks. (4) The so-called "same-opposite side effect'' of the HCS is confirmed to exist. That is, the shocks whose associated flares are located on the same side of the HCS as the Earth (called as "same side events'') have a greater chance of reaching the Earth than those shocks with their associated flares on the opposite side ("opposite side events''). Here for the first time, a comprehensive sample of solar transient events of both arriving and nonarriving ones (at Earth) is used to testify to the same-opposite side effect. These results would be valuable in understanding the solar-terrestrial relations, and helpful for space weather prediction.
: Authentically leading groups: The mediating role of collective psychological capital and trust

Summary Although there have been recent theoretical advances in what is increasingly being recognized as authentic leadership, research testing possible mediating processes and the impact on grouplevel outcomes has not received attention. To help address this need, this study examined at the group level of analysis the role that collective psychological capital and trust may play in the relationship between authentic leadership and work groups’ desired outcomes. Utilizing 146 intact groups from a large financial institution, the results indicated a significant relationship between both their collective psychological capital and trust with their grouplevel performance and citizenship behavior. These two variables were also found to mediate the relationship between authentic leadership and the desired group outcomes, even when controlling for transformational leadership. Implications for future research and practice conclude the paper. Copyright # 2009 John Wiley & Sons, Ltd.
