Abstract

Purpose

The purpose of this study is to evaluate the rainfall intensities and their limits for durations from 0.25 to 8 h with return periods from 2 to 100 years for Ca Mau City in Vietnam.

Design/methodology/approach

First, the quality of the historical rainfall data series in 44 years (1975–2018) at Ca Mau station was assessed using the standard normal homogeneity test and the Pettitt test. Second, the appraised rainfall data series are used to establish the rainfall intensity-duration-frequency curve for the study area.

Findings

Based on the findings, a two-year return period, the extreme rainfall intensities (ERIs) ranged from 9.1 mm/h for 8 h rainstorms to 91.2 mm/h for 0.25 h. At a 100-year return period, the ERIs ranged from 18.4 mm/h for 8 h rainstorms to 185.8 mm/h for 0.25 h. The results also show that the narrowest uncertainty level between the lower and upper limits recorded 1.6 mm at 8 h for the two-year return period while the widest range is at 42.5 mm at 0.25 h for the 100-year return period. In general, the possibility of high-intensity rainfall values compared to the extreme rainfall intensities is approximately 2.0% at the 100-year return period.

Originality/value

The results of the rainfall IDF curves can provide useful information for policymakers to make the right decisions in controlling and minimizing flooding in the study area.

Abstract

Purpose

The purpose of this study is to evaluate rice farmers’ perceptions on the manifestations of the climate change and identify efficient strategies and determinants of adoption of these strategies in the Republic of Benin.

Design/methodology/approach

Surveys were conducted using participatory research appraisal tools and techniques, such as direct observation, individual interviews and field visits through a questionnaire for data collection. A total of 418 rice farmers across 39 villages located in the three climatic zones of the Republic of Benin were interviewed. Farmers’ perceptions, temperature from 1952 to 2018 and rainfall from 1960 to 2018 data obtained from meteorological stations were analysed using descriptive and inferences statistics.

Findings

All the surveyed farmers were aware of climate change and perceived diverse manifestations including the delay in rainfall regarded as the most important risk. They perceived that deforestation, no respect for the laws of nature and desacralization of morals, no respect for cultures and the traditional rainmakers are the main causes of climate change. The disruption of agricultural calendar and the reduction in rice yield were perceived as the main impacts of climate change in rice production. They used various approaches to adapt and mitigate climate change effects. The adoption of adaptation strategies was influenced either negatively or positively by the household size, land size, education level, membership to rice farmer’s association, training in rice production, access to extension services, use of improved varieties and the location in climatic zones.

Research limitations/implications

For each climatic zone of the Republic of Benin, weather data were collected in only one meteorological station.

Practical implications

The study showed that it is important to educate rice farmers on the scientific causes of climate change for better resilience. There is an urgent need to train rice farmers in irrigation and water management techniques to cope with climate variability. To promote irrigation, the authors suggest the establishment of a subsidy and credit mechanism by the government. Factors that influenced adoption of efficient adaptation strategies to climate events must be taken into account for future adaptation policies in the Republic of Benin.

Originality/value

This study provided an overview of the perceptions and adaptations of rice farmers along the climatic gradient in the Republic of Benin. Therefore, the knowledge of the determining factors of the adaptation strategies used by rice farmers could be used in the setting up of effective climate change resilience policies in Benin.

Abstract

Purpose

This study aims to analyze the value-based health-care model in defining a strategy to guide the evolution of health-care organizations toward a value-oriented model. To improve the quality of care by ensuring economic sustainability, it is necessary to redefine the concept of competition in healthcare and align it with the concept of maximizing value for patients.

Design/methodology/approach

Performance measurement is a crucial aspect of the analysis of health-care organizations. Porter developed an effective analytical technique and presented the measurement of health-care outcomes based on health conditions, the efficiency of health-care organizations and the type of service provided.

Findings

Clinical outcomes and data on the costs of care of each patient are essential to evaluate improvement in treatment value over time. Engaging in the evaluation of what happens to patients in their course of care enables the expansion of the measurement of outcomes because it measures all the health services related to it.

Originality/value

Building a health-care system based on the value and continuous improvement of care and services provided is a goal shared by many countries and international organizations. Today, the analysis of outcomes is important for making informed decisions, directing and planning clinical and organizational changes by improving the quality of care and services.

Abstract

Purpose

This paper aims to present new evidence from the Cambridge Study in Delinquent Development (CSDD) showing the extent to which obstetric (e.g. abnormal birth weight, confinement at birth, severe abnormality of pregnancy, etc.) and early childhood and family factors (illegitimate child, unwanted conception, family overcrowding, etc.) have predictive effects on psychopathic traits measured later in life at age 48 years.

Design/methodology/approach

Data collected in the CSDD are analysed. This is a prospective longitudinal study of 411 London men from age 8 to age 61 years.

Findings

The results suggest that none of the obstetric problems were predictive of adult psychopathy. However, some other early childhood factors were significant. Unwanted conception (by the mother) was significantly associated with high psychopathy. The likelihood of being an unwanted child was higher when the mother was younger (19 years or less), and when the child was illegitimate. The poor health of the mother and living in an overcrowded family were also significant in predicting psychopathy in adulthood, as well as both psychopathic personality (F1) and psychopathic behaviour (F2).

Originality/value

These findings suggest the influence of very early emotional tensions and problematic social background in predicting psychopathic traits in adulthood (at age 48 years). They also emphasise the importance of investigating further the very early roots of psychopathic traits.

Abstract

Purpose

The purpose of this study isto synthesize recent empirical research investigating memory of stressful critical incidents (both simulated and occurring in the field) among law enforcement officers.

Design/methodology/approach

The study used the approach of systematic state-of-the-art review.

Findings

In total, 20 studies of police and military officers show reduced detail and accuracy of high- versus low-stress incidents, especially for peripheral versus target information. Decrements in memory performance were mediated by the extent of physiological stress responses. Delayed recall accuracy was improved among officers that engaged in immediate post-incident rehearsal, including independent debriefing or reviewing body-worn camera footage.

Research limitations/implications

Most studies were not found through systematic database searches, highlighting a need for broader indexing and/or open access publishing to make research more accessible.

Practical implications

By understanding how stress physiology enhances or interferes with memory encoding, consolidation and recall, evidence-based practices surrounding post-incident evidence gathering are recommended.

Social implications

The current review addresses common public misconceptions of enhanced cognitive performance among police relative to the average citizen.

Originality/value

The current work draws from scientific knowledge about the pervasive influence of stress physiology on memory to inform existing practices surrounding post-incident evidence gathering among police.
