Multi-Product Firms and Exporting: A Developing Country Perspective

In this paper, we shed additional light on the complex relationship between multinational enterprises (MNEs), exporting and economic development by making a distinction between single and multi-product firms. As far as we are aware, the export behavior of foreign firms in a multi-product setting has not previously been considered for a developing country. Using firm-level data for Thailand we show that the number of goods produced causes a much larger variation in exports volumes than in total production. Whilst the number of products exported and the total volume exported is positively correlated we find, in contrast to US studies, a surprising negative correlation between the number of products produced and the volume of production. We then go on to investigate for the first time the characteristics of multi-product firms and the number of products they produce and find the distinction between foreign owned and domestic firms as well as between foreign exporters and foreign non-exporters is important. The presence of foreign firms producing single products solely for the domestic market as well as those producing many products for export demonstrates the diversity of behavior of foreign firms in developing countries and emphasises that a foreign presence may not be as beneficial as policy makers are led to believe.Multinationals, Firm characteristics, Multi-product, Exports

Firm Heterogeneity and Export Participation: A New Asian Tiger Perspective

This paper investigates the relationship between firm heterogeneity and a firm’s decision to export, using the annual survey of Thai manufacturing firms from 2001 to 2004. A significant contribution of this paper is that we are, for the first time, able to break down FDI by country of origin to observe whether the behavior of MNEs differs by region of origin. We find that entry sunk costs and firm characteristics are important factors in explaining a firm’s decision to export. Another important determinant is the ownership structure of the firm, with foreign owned firms having a higher probability of exporting than domestically owned firms although this differs across country of ownership with potentially important policy implications. Export platform FDI is used to explain the behavior of foreign firms that invest in Thailand. Using three measures of total factor productivity, we also find that highly productive firms self-select into the export market. The implication for governments of developing countries is the need to think carefully about how and to whom they target their inward FDI policies as a means of growth. The heterogeneous behavior of multinationals from different nations means that policies targeting specific regions or countries may be preferable to general tax concessions or the implementation of special economic zones that are open to all.FDI, exports, firm heterogeneity, development

Growth, Foreign Direct Investment and the Environment: Evidence from Chinese Cities

In this paper we investigate the relationship between economic growth and industrial pollution emissions in China using data for 112 major cities between 2001 and 2004. Using disaggregated data we separate FDI inflows from Hong Kong, Macao and Taiwan from those of other foreign economies. We examine four industrial water pollution indicators (wastewater, chemical oxygen demand, hexavalent chromium compounds, and petroleum-like matter) and four industrial air pollution indicators (waste gas, sulphur dioxide, soot and dust). Our results suggest that most air and water emissions rise with increases in economic growth at current income levels. The share of total output produced by firms from Hong Kong, Macao and Taiwan has a positive effect on emissions although this effect is only significant for three industrial water pollution emissions. The share of total output produced by firms from other foreign economies can be beneficial, detrimental or neutral, depending on the pollutants considered. --FDI,economic growth,pollution,cities

Status of major southern California marine sport fish species with management recommendations, based on analyses of catch and size composition data collected on board commercial passenger fishing vessels from 1985 through 1987

This report on the status of major southern California marine sport fish species, together with management recommendations, is based on analyses of catch and size composition data, which were collected on board Commercial Passenger Fishing Vessels (CPFV) from 1985 through 1987. The project was designed to determine the status of those fishes that support the CPFV industry, and to make management recommendations when deemed necessary. We collected and analyzed data based on random, stratified, on-board sampling of weekday (excluding holidays), open CPFV's on a year-round basis. We sampled 1/2-day, 3/4-day, and full-day type trips at a level of 5%. The survey area extended from below the United States-Mexican border to Point Arguello. Catch estimates were extrapolated to include weekday as well as weekend and holiday, open and chartered CPFV's. We sampled 736 CPFV trips in 1985, 650 in 1986, and 631 in 1987. We encountered 180 species of fishes, including 49 species of rockfishes. We performed detailed analyses on 14 non-rockfish species and 12 rockfish species, as well as all fishes as a group and all rockfishes as a group. We found a moderate increase in total catch of combined fish species between this study and one in the mid-1970's, due primarily to sizeable increases in catches of Pacific mackerel, kelp bass, barred sand bass, and barracuda. However, we also found that there has been more than a 50% decline in the CPFV rockfish catches, due primarily to substantial decreases in catches of bocaccio, chilipepper, and olive rockfish. We have recommended that the current 15-rockfish bag limit regulation be reduced to a 10-rockfish bag limit, and that additional and equitable conservation measures also be implemented on the commercial rockfish fishery.

A Tale of Two Cycles: Co-Fluctuations Between UK Regions and the Euro Zone

We examine the patterns and determinants of business-cycle correlations among eleven UK regions and six euro-zone countries over the 1966-1997 period, using GMM to allow for sampling error in comparing estimated correlations. The British business cycle is found to be persistently out of phase with that of the main euro-zone economies, and the trend is towards lower correlations. We detect only minor cyclical heterogeneity among UK regions. Differences in sectoral specialisation drive some of the asymmetry in GDP fluctuations, but they do not appear significant in explaining the observed reduction in UK-EU business-cycle correlations over time.business cycles; co-fluctuations; UK regions; European monetary union; optimum currency areas

Micro-Place Disorder, Subjective Powerlessness and Violent Youth Group Involvement: Testing an Integrative Control Theory

In this study we test an integrative theory that seeks to explain why youth that live in disordered micro-places have an increase likelihood of becoming involved in a violent youth group. The emerging integrative theory is based on the principle of conceptual end-to-end integration and is the result of an attempt to integrate (1) a contemporary version of subjective powerlessness theory with (2) an integrative control framework of violent youth group involvement. We submit the thesis that the both aforementioned models are highly suitable for conceptual integration as micro-place disorder is a common antecedent. In addition, both models share an intervening mechanism in the observed micro-place disorder- violent youth group involvement relationship: the concept of normlessness. An integrative model allows for the study of multiple pathways through which micro-place disorder and subjective powerlessness affect the likelihood of becoming involved in a violent youth group. Using path analyses for continuous and dichotomous outcomes we test key propositions of our theoretical elaboration. Our research is based on a large sample of youths in early adolescence (N=2,486) in the urban context of Antwerp, the second largest city of Belgium. The results indicate that micro-place disorder increases decreases parental monitoring and increases feelings of subjective powerlessness. Normlessness and low self-control are important mediators in the "causal chain" between micro-place disorder, subjective powerlessness and violent youth group involvement. Low self-control and lifestyle risk further mediate the effects of subjective powerlessness, normlessness and micro-place disorder. The implications of these findings for future studies of violent youth group involvement are discussed

An atomic scale comparison of the reaction of Bioglass® in two types of simulated body fluid

A class of melt quenched silicate glasses, containing calcium, phosphorus and alkali metals, and having the ability to promote bone regeneration and to fuse to living bone, is produced commercially as Bioglass. The changes in structure associated with reacting the bioglass with a body fluid simulant (a buffered Tris(hydroxymethyl)aminomethane growth medium solution or a blood plasma-like salt simulated body fluid) at 37°C have been studied using both high energy and grazing incidence x-ray diffraction. This has corroborated the generic conclusions of earlier studies based on the use of calcia–silica sol-gel glasses whilst highlighting the important differences associated with glass composition; the results also reveal the more subtle effects on reaction rates of the choice of body fluid simulant. The results also indicate the presence of tricalcium phosphate crystallites deposited onto the surface of the glass as a precursor to the growth of hydroxyapatite, and indicates that there is some preferred orientation to their growth

Pharmacological and behavioural interventions to promote smoking cessation in adults with schizophrenia and bipolar disorders: a systematic review and meta-analysis of randomised trials

Objective: Smoking in people with serious mental illness is a major public health problem and contributes to significant levels of morbidity and mortality. The aim of the review was to systematically examine the efficacy of methods used to aid smoking cessation in people with serious mental illness. Method: A systematic review and meta-analysis of randomised controlled trials to compare the effectiveness and safety of pharmacological and behavioural programmes for smoking cessation in people with serious mental illness. Electronic databases were searched for trials to July 2018. We used the Cochrane Collaboration’s tool for assessing the risk of bias. Results: Twenty-eight randomised controlled trials were identified. Varenicline increased the likelihood of smoking cessation at both 3 months (risk ratio (RR) 3.56, 95% CI 1.82 to 6.96, p=0.0002) and at 6 months (RR 3.69, 95% CI 1.08 to 12.60, p=0.04). Bupropion was effective at 3 months (RR 3.96, 95% CI 1.86 to 8.40, p=0.0003), especially at a dose of 300 mg/day, but there was no evidence of effect at 6 months (RR 2.22, 95% CI 0.52 to 9.47, p=0.28). In one small study, nicotine therapy proved effective at increasing smoking cessation up to a period of 3 months. Bupropion used in conjunction with nicotine replacement therapy showed more effect than single use. Behavioural and bespoke interventions showed little overall benefit. Side effects were found to be low. Conclusion: The new information of this review was the effectiveness of varenicline for smoking cessation at both 3 and 6 months and the lack of evidence to support the use of both bupropion and nicotine products for sustained abstinence longer than 3 months. Overall, the review found relatively few studies in this population

Autoimmunity and the oral cavity

Purpose of Review: This review aims to make the oral health practitioner and researcher aware of autoimmune diseases that present in the mouth and have implications for oral health. Specifically, the autoimmune pathophysiology, examples of treatments, sequelae, and impact on oral health will be discussed. The limitations of our current knowledge and understanding of these diseases will also be highlighted. Recent Findings: Over the past decade, it has become clear that there is a bidirectional relationship between oral health and autoimmune disease at other body sites; including diabetes and rheumatoid arthritis. Improving the oral health of patients with autoimmune diseases may reduce morbidity associated with such diseases. Summary: Autoimmune diseases impact the oral cavity both directly and indirectly and are increasing in prevalence. As such, there is a growing need for the oral health practitioners to be aware of how autoimmune disease impacts the oral cavity. Further research is necessary to improve our understanding of the bidirectional relationship between oral health and autoimmune disease
