Home-related injuries among under-five-year children and mothers' care regarding injury prevention in rural areas

This cross-sectional study was conducted in rural areas of Twiserkan (Toyserkan) County, in Iran, to assess factors associated with home-related injuries among under-five-year children and their mothers’ care regarding injury prevention. Mothers who had their under-five-year-old children injured within a 12-month period were identified from recorded information in Twiserkan Health Center. Then, data were gathered using pre-tested questionnaire and through interview with injured children's mothers. The questions were about characteristics of the children's injuries and their mothers’ care regarding injury prevention, using PRECEDE (Predisposing, Reinforcing, and Enabling Constructs in Educational/Environmental Diagnosis and Evaluation) model with focus on knowledge and attitude; enabling and reinforcing factors; and mothers' preventive behaviours. The study results showed that 197 out of 210 total identified mothers took part in the study. The reported injuries were 11.68%, 39.09%, and 49.24%, respectively, for severe, moderate, and mild cases. Fall was the most frequent injury with 35%. Among PRECEDE model constructs, there was a statistically significant correlation between mothers' knowledge and injury severity among children. Home-related injuries are an important health problem among study population and their prediction and prevention are necessary. Enhancement of mothers’ knowledge can be helpful to improve child injury prevention.     

Dynamic land use and land cover changes and their effect on forest resources in a coastal village of Matemwe,Zanzibar, Tanzania

Recent land cover change estimates show overall decline of tropical forests at the regional and global scales caused by multiple social, cultural and economic factors. There is an overall concern on the prevailing land use practices, such as shifting cultivation and extraction of forest materials as agents of forests losses, but also new, emerging land uses are threatening tropical forests. Understanding of the long-term development and driving forces of forest changes are needed, especially at local levels where many decisions on forest policies and land uses are made. This paper addresses the importance of such information for improved estimates of forest dynamics by studying local level land cover and land use changes during the last 50–70 years in the Eastern African tropical island of Zanzibar, Tanzania. The paper discusses the role of traditional and new land uses mainly subsistence farming, tourism and government interference through tree planting, in the long-term development of the forests at the village level. The material for the study is gathered from the interpretation of archival maps and aerial photographs combined with contemporary digital aerial photographs. The analyses are based on the mapping, spatial sampling and spatio-temporal change trajectory analysis (LCTA) of forest land cover, forest land uses and settlement patterns with GIS and statistics. Six distinct forest land cover change trajectories were identified and these illustrate dynamic and heterogeneous nature of the forests. Closed forest cover has dominated throughout due to cyclical land use patterns, but over 70% of the land area has been continuously transforming between closed, semi-open and open land cover conditions. Land use turnover rates indicate that hardly any forest areas are left untouched from the forces, which remove and re-establish forest vegetation in the long run. Land cover and land use change trajectories are spatially fragmented in the studied landscape. Majority of forest loss-gain dynamics is caused by shifting cultivation, while forest losses are most dramatic along the coast, where traditional and new land uses meet and land uses pressures are highest. The study suggests that landscape change trajectory analyses, where contemporary and historical information on land uses and land cover changes are spatially linked, can provide valuable aspects into local level forest land use planning and management strategies. For the case study, the findings suggest the following key forest management strategies for consideration: (1) establishment of a protected forest/scrubland in participation with the local stakeholders, especially the farmers, (2) promotion of areas for permanent agricultural practices, while simultaneously introducing management controls in the traditional slash-and-burn farming areas, and (3) promoting new livelihood opportunities for the farmers, who have traditionally been dependent on forest resources, meanwhile introducing alternatives for fuel wood for cooking.     

Awareness as a foundation for developing effective spatial data infrastructures

The development of an effective spatial data infrastructure (SDI) often occurs in a fragmented organizational environment requiring a high level of inter-organizational collaboration. Different organizations from various jurisdictions need to work together closely when agreeing on how they will jointly register, store, use and share data and how they will make their data available to the wider society. However, this collaboration is generally regarded as very difficult. For example people often resist data sharing across organizational boundaries due to loss of control, power and independency. Organizational issues are thus considered one of the fundamental constraints to inter-organizational sharing of spatial data.     

Dependence and Stability of the Demand for Money in a Small open Economy: The Case of Côte-d'Ivoire

Abstract: This paper investigates the effects of foreign variables on the demand for money in Côte-d'Ivoire during 1970. I-1986. IV. In the model specification, we consider that Côte-d'Ivoire is a member of the Franc zone. Within the zone, the CFA Franc is pegged to the French Franc, but outside the zone or with the generalized floating system, the CFA Franc espouses the form taken by the French Franc against other major currencies. The model satisfactorily explains behavioral relationships under these two regimes. Domestic determinants of the demand for real cash balances are the real GDP, the expected rate of inflation, the degree of credit restraint, and expectations of economic instability. International influences are captured by foreign interest and exchange rates. Stability and causality tests indicate that the money demand relation has been stable over time and is highly influenced by foreign interest rates. Résumé: Le présent document étudie les incidences des variables extérieures sur la demande de monnaie en Côte-d'Ivoire de 1970. I à 1986.IV. Dans la spécification du modéle, nous considérons que la COcte-d'Ivoire est membre de la Zone Franc, mais hors de la Zone ou avec le systéme flottant généralisé, le Franc CFA adopte les formes proses par le Franc Francais par rapport aux devise fortes. Le modéle explique de manié satisfaisante les rapprots aux devises fortes. Le modéle explique de manié satisfaisante les rapprots de comportement sous ces deux régimes. Les facteurs déterminants sur la demande de bilans de trésorerie réelle sont le PIB réel, le taus d'inflation prévisionnel, le degré de pénurie de crédit, les menaces d'instabilitééconomique. Les influences internationales sont représentées par les intéréts étrangers et les taux de change. Les tests de stabilité et der cause à effect indiquent que le rapport de la demande de monnaie a éaté stable au fil du temps et est fortement influencé par les taus d'intérét étrangers.     

The Iranian Manager: Work Values and Orientations

Managerial value systems along with individualism-collectivism concepts were examined among 768 managers in Iran. The sample was randomly selected from state, private, and mixed organizations. The participants ranked conformist and sociocentric values high. In addition, the participants displayed a high tendency toward collectivism and a weak commitment to individualism. Furthermore, existential value was highly correlated with individualism-collectivism measures.     

Churn analysis for an Iranian mobile operator

To survive in the challenging environment of a global market, organizations must recognize and analyze customer attitudes. To be competitive, organizations must recognize and forecast customer preferences and behaviors to maximize customer retention before their rivals do so. This research identifies factors that affect customer churn, the single most valuable of an organization's assets. One year's data from call log files relating to 3150 customers were selected randomly from an Iranian mobile operator call-center database. Binomial Logistic Regression was the method of analysis used in this research. The results of this research indicate that a customer's dissatisfaction, their amount of service usage and certain demographic characteristics have the most influence on their decision to remain or churn. The results also imply that customer status (active or inactive status) mediates the relationship between churn and the cause of churn. The Iranian government's current plan to privatize the telecommunications industry without deregulation leads to a non-square competition environment. Deregulation in favor of delegating more authorities of customer care is necessary in order to develop a square private competition environment in the Iranian mobile telecommunications industry.     

Further evidence on the robustness of the Tobit estimator to heteroskedasticity

When the error terms in a Tobit model are heteroskedastic, the MLE which assumes homoskedasticity is inconsistent. For the special case of a constant-term-only model, we investigate the size of the inconsistency. The inconsistency is greater the greater the heteroskedasticity and the greater the degree of censoring (i.e., the greater the number of limit observations). However, the inconsistency is much smaller than in the corresponding truncated-normal model considered by Hurd.     

Prioritizing Brand Equity Methods From Customers’ Perspective for the Food Industry

Brand equity assessment is an important measurement of strategic value for internal use as well as for external stakeholders. Although there are a number of methods available for brand evaluation, it is still uncertain which approach is best. Yet almost no research exists that has prioritized the existing brand equity methods from the perspective of different stakeholders through a survey. In this article a model is developed for prioritizing brand equity methodologies from the viewpoint of customers as a stakeholder of brand equity. The developed model can help businesses to deploy a brand equity methodology that best considers the criteria of their customers as one of their key stakeholders. The criteria of this process are the expectations of customers from a brand. The priority of these criteria sets via a structured questionnaire filled by customers. Then the analytical hierarchy process (AHP) incorporates to prioritize the methodologies versus these criteria. This study set out to prioritize the brand equity pool to help practitioners and academics in assessing the alternative techniques and selecting the most relevant one that measures the most important criteria of brand in the eyes of customers.     

Collective mental accounting: an integrated behavioural portfolio selection model for multiple mental accounts

We propose a behavioural portfolio selection model called collective mental accounting (CMA), which integrates all mental sub-portfolios (mental accounts) in one mathematical model. Moreover, this study contributes to the literature of behavioural portfolio selection in three further ways: first, the CMA model can determine the proportions of wealth allocated to each mental sub-portfolio with and without input from the investor. Second, unlike other mental accounting models (MA), in CMA it is possible to define constraints on total asset holdings such as short-selling, and cardinality constraints. Third, in order to make CMA more tractable and mathematically elegant, we obtain a semi-definite programming representation of the model. We also present a numerical example to investigate the effects of short-selling constraints as well as to compare the portfolio recommendations, utility functions, feasibility, and optimality of the CMA and MA models. The results reveal that although both models’ solutions are mean-variance efficient, CMA outperforms MA in terms of behavioural efficient frontier and utility functions.
