The Impact

A capacity for the animal to recover quickly from the impact of physical and social stressors and disease challenges is likely to improve evolutionary fitness of wild species and welfare and performance of farm animals. Salience and valence of stimuli sensed through neurosensors, chemosensors and immunosensors are perceived and integrated centrally to generate emotions and engage physiological, behavioural, immune, cognitive and morphological responses that defend against noxious challenges. These responses can be refined through experience to provide anticipatory and learned reactions at lower cost than innate less-specific reactions. Influences of behaviour type, coping style, and affective state and the relationships between immune responsiveness, disease resistance and resilience are reviewed. We define resilience as the capacity of animals to cope with short-term perturbations in their environment and return rapidly to their pre-challenge status. It is manifested in response to episodic, sporadic or situation-specific attributes of the environment and can be optimised via facultative learning by the individual. It is a comparative measure of differences between individuals in the outcomes that follow exposure to potentially adverse situations. In contrast, robustness is the capacity to maintain productivity in a wide range of environments without compromising reproduction, health and wellbeing. Robustness is manifested in response to persistent or cyclical attributes of the environment and is effected via activity of innate regulatory pathways. We suggest that for farm animals, husbandry practices that incorporate physical and social stressors and interactions with humans such as weaning, change of housing, and introduction to the milking parlour can be used to characterise resilience phenotypes. In these settings, resilience is likely to be more readily identified through the rate of return of variables to pre-challenge or normal status rather than through measuring the activity of diverse stress response and adaptation mechanisms. Our strategy for phenotyping resilience of sheep and cattle during weaning is described. Opportunities are examined to increase resilience through genetic selection and through improved management practices that provide emotional and cognitive enrichment and stress inoculation.

Regulatory Pathways

The temperament of farm animals can influence their resilience to everyday variations within the managed production environment and has been under strong direct and indirect selection during the course of domestication. A prominent objective measure used for assessing temperament in beef cattle is the behavioral flight response to release from confinement in a crush or chute. This behavioral measure, termed flight speed (also known as escape velocity) is associated with physiological processes including body temperature, feeding behavior, growth rate, carcass composition, immune function, and health outcomes. This review examines the functional links between this suite of traits and adrenergic activity of the sympathetic nervous system and the adrenomedullary hormonal system. It is suggested that flight speed is the behavioral aspect of an underlying “flightiness” temperament syndrome, and that elevated adrenergic tone in animals with a high level of flightiness (i.e., flighty animals) tunes physiological activities toward a sustained “fight or flight” defense profile that reduces productivity and the capacity to flourish within the production environment. Nonetheless, despite a common influence of adrenergic tone on this suite of traits, variation in each trait is also influenced by other regulatory pathways and by the capacity of tissues to respond to a range of modulators in addition to adrenergic stimuli. It is suggested that tuning by adrenergic tone is an example of homeorhetic regulation that can help account for the persistent expression of behavioral and somatic traits associated with the flight speed temperament syndrome across the life of the animal. At a population level, temperament may modulate ecological fit within and across generations in the face of environmental variability and change. Associations of flight speed with the psychological affective state of the animal, and implications for welfare are also considered. The review will help advance understanding of the developmental biology and physiological regulation of temperament syndromes.

This article reviews the impact of sweet potato (Ipomoea batatas (L) Lam) on the world economy, its uses, and efforts in Nigeria to popularize its cultivation and acceptability. The potential and average yields of 87 and 20–30 t/ha respectively (over a three–six month growing period) under improved management practices, its ecological flexibility, its low input requirements, the wide range of recipes based on its flour, and easy propagation by vine cuttings distinguish the sweet potato as a potentially important industrial and staple food crop. Problems relating to sweetness, dominant flavour, and the colour of the cooked product are identified as ones requiring solution if its acceptability is to be enhanced.

The Impact

While public concern over the welfare of farm animals is believed to have intensified across Australia in recent years, no empirical research has sought to examine and quantify the heterogeneity in farm animal-welfare (FAW) concerns among Australian meat consumers. The present study is the first to address this knowledge gap. Data were collected in 2015 by using a comprehensive online survey instrument completed by a representative sample of 1009 Australian meat consumers. Sample quotas were set for age, gender and location. Using these data, we were able to segment meat consumers according to their attitudes towards FAW and perceptions regarding the environmental impact of meat production. Six unique segments were identified and characterised by purchase behaviour, livestock-management knowledge, farming background and experience, beliefs regarding the consumer/farmer implications of improved FAW, influential information sources, participation in FAW-related activities and socio-demographic variables. Our findings showed that the majority of Australian meat consumers (70%) hold neutral views regarding FAW. However, there are two segments, termed ‘concerned-FAW’ (10%) and ‘anti-FAW’ (20%), which expressed strong views with respect to FAW. Overall, consumer knowledge regarding livestock-management practices was low across all segments, with only 11–42% of consumers indicating that they felt sufficiently informed about FAW. This insight into perceptions of FAW by different segments and the impact of meat production on the environment can assist the industry in developing targeted information campaigns to address consumer concerns and allow better-informed meat purchase decisions.

The flow series for the River Thames near its tidal limit is one of the most studied in the world. Its length and completeness, and the richness of the historical information which augments the formal flow record, ensures that the series is of immense value. However, the variability in flood magnitude and frequency that it captures needs to be interpreted with caution. The homogeneity of the time series is influenced by a wide range of factors, including changes in the hydrometric capability of the gauging station and the impact of differing water, river and land management practices on the flow regime. Nevertheless, both the daily flow series and the record of lock levels provide some reassuring signals regarding the resilience of the Thames to fluvial flood risk in a warming world. Since routine flow measurement began in 1883, the Thames basin has seen a substantial rise in air temperature and a tendency for both winter rainfall and annual runoff to increase. There is no trend in fluvial flood magnitude however, partly reflecting a decline in snowmelt contributions to major floods and annual maximum lock levels show a significant decline, reflecting a highly sustained programme of river management.

SUMMARYIn farm animals, restricted housing conditions or inadequate management practices during gestation may be potential stressors for the mother, with possible consequences on the growth, vitality, health and welfare of the dam and its offspring, and thus can have economic as well as ethical implications. The current review summarizes data from studies in pigs on the impact of maternal stress during gestation on the litter characteristics and phenotypic traits of offspring. The outcomes from the different experimental models using either maternal stress paradigms or artificially increased maternal cortisol are presented, and possible reasons for the consistent or divergent results are discussed. Maternal stress models are of particular importance, because social stress, restraint, rough handling and heat or cold stress are of practical relevance during housing of pregnant sows, whereas in other models the specific role of maternal cortisol as a mediator for pre-natal stress is studied. The data reveal that pre-natal stress in pigs can impair growth and modify the immune function, stress reactivity and behaviour of offspring. There is evidence that the materno-foetal cortisol regulation is a major determinant of the alterations in offspring. Neuroendocrine and behavioural data in the offspring indicate that pre-natally stressed pigs can express a modified phenotype characterized by increased reactivity of the hypothalamic–pituitary–adrenal axis, altered emotionality, more fearfulness in a novel environment and disturbed social and maternal behaviour. Further research is needed and should focus on the long-term consequences on immune function, reproductive traits and maternal behaviour in female offspring used as breeding animals.

AbstractThe impact of internal and external parasitism on productivity of farm animals is considered for cattle, sheep, pigs and poultry. The parasitic challenge experienced and the outcome of that challenge is a dynamic one in which environment, management practices, including housing or grazing management, nutritional status, the host's ability to develop effective immunity and the speed with which this can occur, play a significant role. Much of our assessment of the impact of infection comes from pathophysiological and nutritional studies with contrived infestations. A common feature of all infestations is reduced efficiency of food utilization through reduction in food intake, though in some cases increases in nutrient requirement are induced as a result of damage to or loss of host tissue. Assessment of the impact on productivity in the field is technically very difficult and must take account of fluctuating challenge, determined by environmental and management decisions, and the manager's objectives for the performance of a particular category of livestock. This review attempts to integrate the assessment of losses in productivity based on pathophysiological studies with those based on protection of groups of livestock in production systems by regular pesticide use. Throughout the review the limitations inherent in both approaches and in our knowledge of how parasites impair productivity of the host are emphasised.

Sugar is an important source of energy for the human body although it receives blame for many health problems, without it, the body would cease to function properly. Nearby thirty percent of the world sugar comes from sugar beet. Production of sugar beet globally spans diverse regions with a wide range of climatic and agro-ecological regions which shows exclusive management challenges. Fertilizer or nutrient management is one of the practices that associate with fertilizer use efficiency and production of the crops including sugar beet. As the nutrient management interacts with different agro-ecological areas and soils, the fertilizer recommendations and management have become regional and site-specific. Maximizing beet and sugar yields, the knowledge of the management of the fertilizers or nutrition is very essential. This article is to understand the impact of different fertilizers in different management practices including the major nutrients of the crop, fertilizer rate, timing, and method of application either solely or in a mixture or integrated manner with reviewing diverse research experiments. Moreover, it will help to approach future strategies and needs for making the production of sugar beet as a cost-effective crop with new improving management technologies for the farmers.

Abstract. In the study, the neural basis of emotional reactivity was investigated. Reactivity was operationalized as the impact of emotional pictures on the self-reported ongoing affective state. It was used to divide the subjects into high- and low-responders groups. Independent sources of brain activity were identified, localized with the DIPFIT method, and clustered across subjects to analyse the visual evoked potentials to affective pictures. Four of the identified clusters revealed effects of reactivity. The earliest two started about 120 ms from the stimulus onset and were located in the occipital lobe and the right temporoparietal junction. Another two with a latency of 200 ms were found in the orbitofrontal and the right dorsolateral cortices. Additionally, differences in pre-stimulus alpha level over the visual cortex were observed between the groups. The attentional modulation of perceptual processes is proposed as an early source of emotional reactivity, which forms an automatic mechanism of affective control. The role of top-down processes in affective appraisal and, finally, the experience of ongoing emotional states is also discussed.

The aim of this paper is to study if and how impression management varies during different phases of the legitimation process, in particular during the legitimacy building and legitimacy repairing phases (Suchman, 1995). We aim at understanding whether and how the disclosure tone adopted by a company in the two different moments is diverse and thus functional to the intrinsic objective of the each phase. The empirical analysis focuses on the case of British Petroleum Plc. We investigated the impression management practices undertaken by the company both during the preparation of the rebranding operation, i.e. a situation in which the company is trying to build legitimacy; and during the happenings of two legitimacy crises, like the explosion of the refinery in Texas City and the oil spill in the Gulf of Mexico. The evidence appears in line with the theoretical prediction of legitimacy theory. Results show that while the company tends to privilege image enhancement techniques during the legitimacy-building phase, it uses more obfuscation techniques when managing a legitimacy-repairing process. Moreover, the analysis suggests that the company makes more extensive use of impression management techniques in the disclosures addressed to shareholders, investors and other market operators than in the disclosures addressed to the wide range of other stakeholders.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.
