Assessing dairy cow welfare during the grazing and housing periods on spring-calving, pasture-based dairy farms.

The different periods characterizing spring-calving, pasture-based dairy systems common in Ireland have seldom been the focus of large-scale dairy cow welfare research. Thus, the aim of this study was to devise and conduct an animal-based welfare assessment during both the grazing and housing periods on spring-calving, pasture-based dairy farms, to identify areas for improvement and establish benchmarks for indicators of good welfare. Assessment of seven animal-based welfare indicators was conducted during two visits (one each at grazing and housing) to 82 commercial dairy farms in southern Ireland. Herd-level descriptive statistics were performed for all welfare indicators at each visit, and differences between visits were analyzed using paired t-tests and Wilcoxon signed-rank tests. A mean of 9% and 10% clinically lame cows (mobility scores 2 and 3) were observed at housing and grazing, respectively. Recommended body condition scores (BCS) were not met for a mean of 13% of cows at grazing and 23% at housing, with more over-conditioned cows present at housing than grazing (P < 0.001). Ocular discharge was uncommon in both periods. Prevalence of moderate and severe nasal discharge combined was lower during housing (5%) than grazing (7%). In both periods, similar mean levels of tail injury were observed: 2% to 3% of cows with tail lacerations, 9% with broken tails, and 8% (measured at housing only) with docked tails. Integument alterations involved primarily hair loss and were most prevalent on the hindquarters (26%) during grazing and on the head–neck–back (66%) and the hindquarter (32%) regions during housing. Cows displayed an avoidance distance of >1 m (indicative of a fearful response) from an approaching human in an average of 82% of grazing cows and 42% to 75% of housed cows, dependent on test location. Opportunities to improve welfare in this system were identified in the areas of tail injury prevention, nasal health, and the management of indoor housing and feeding. The performance of the top 20% of farms for each welfare indicator was used to establish benchmarks of: 0% to 5% clinical lameness, 0% to 12% of cows outside recommended BCS, 0% to 27% ocular discharge, 2% to 16% nasal discharge, 0% tail lacerations and docked tails, 0% to 3% tail breaks, 0% to 14% integument alterations, and 4% to 74% for avoidance distance of >1 m. These represent attainable targets for spring-calving pasture-based farms to promote good dairy cow welfare.

Single-rating, multi-rating 360° performance management and organizational outcomes: evidence from the UAE

PurposeThis study is an academic attempt to bridge the gap between Western theories and the under-researched non-western contexts by studying the characteristics of traditional and modern performance management systems (PMSs) in the United Arab Emirates (UAE). Drawing on the expectancy theory, this study aims to discuss the significant causal relationship between the implementation of single-rating, multi-rating 360° performance management (PM) and organizational outcomes such as trust, commitment, satisfaction and intention to leave.Design/methodology/approachUsing the self-reported measures and survey method, data were collected from 439 employees from different organizations across the UAE. Explanatory factor analysis, simple linear regression and multi-group were used to test the proposed conceptual model and examine the mediation and moderation impact.FindingsThe study explored the best-practices attributes of the traditional single-rating, multi-rating 360° PM within a non-western context. This study also provides empirical evidence on the significant role of uncertainty avoidance and power distance orientation as a mediator between the relationship between these PMSs and trust, commitment, job satisfaction and intention to leave. Finally, this paper examined the effect of many demographic variables (such as gender, age, industry type […]) on the relationship between the independent variables and the dependent variables.Originality/valueThis study extends research on PM theories and models. Another important aspect of this study is that its model has been tested on the UAE’s data, an underrepresented geographic region in the management literature. Given all the PM’s positive characteristics, the way that this feedback is viewed and interpreted by employees may be moderated according to the employee’s management level, age, gender and many other demographics.

Welfare-Related Behaviors in Chickens: Characterization of Fear and Exploration in Local and Commercial Chicken Strains.

Simple SummaryLocally adapted chicken strains are frequently discussed as a favorable alternative in poultry production. They might serve as dual-purpose and robust strains that have advantageous behaviors, such as exploration and reduced fear reactions, which might support animal welfare in general. Therefore, it is important to characterize welfare-related behaviors, such as fear and exploration, and to identify these behavioral traits among the diversity of chicken strains. The aim of this study was to characterize fear reactions and exploration based on the avoidance of a novel object and the avoidance of a human in three different chicken strains. To identify interesting alternatives for future poultry production, a layer hybrid (Lohmann Brown), a dual-purpose hybrid (Lohmann Dual) and a locally adapted strain (Rhinelander) were tested for their fear and exploration behavior towards unknown objects and humans. Results showed clear differences in fear and exploration between all three strains, regarding fear of objects and humans. The strain-specific results illustrate the high diversity of behavioral traits. The understanding of behavioral diversity, including fear and exploration, might contribute substantially to future breeding programs, including of commercial strains, and the preservation of local strains in general, which can improve animal welfare on a genetic and individual basis.Fear and exploration are crucial traits determining how animals behave in novel situations, and thus, they influence animal welfare. The aim of this study was the characterization of these behavioral traits among different strains to identify interesting alternatives for future poultry production. Whereas the Novel Object Test (NOT) focuses on fear and exploration of novel objects, the Avoidance Distance Test (ADT) addresses this in the context of humans. Here, a commercial hybrid line, a dual-purpose hybrid and a local adapted strain were tested. For the differences between strains and development of fear, Lohmann Brown (n = 714), Lohmann Dual (n = 844) and Rhinelander (n = 458) were observed weekly until maturity. Results show that fear and exploration towards unknown objects and humans are breed-specific (all p < 0.01). Additionally, development of fear in NOT and ADT differed between all three strains (both p < 0.01). The expressions of fear of humans or objects should be regarded as characteristics adapted for different husbandry systems and breeding goals, e.g., high exploratory behavior in aviary or high avoidance of predators in free-ranging husbandry or at least a balanced ratio between fear and exploration. Characterization of behavioral traits among different strains, understanding diversity and integrating these behaviors into future breeding and husbandry systems might reflect the need to preserve local strains and the potential to improve animal welfare.

What Drives Banks to Value Lending Relationships? The Role of the Chief Executive's Cultural Heritage

We explore how bank CEOs' cultural heritage shapes the nexus between lending relationships and the cost of bank loans in the US syndicated loans market. We show that banks led by CEOs that trace their origin in more individualistic and masculine societies are less inclined to share with their borrowers the savings stemming from strong lending relationships. In contrast, banks led by CEOs that originate from societies where uncertainty avoidance and power distance are higher, exhibit a stronger propensity to reward their relationship borrowers with lower loan prices. These findings are consistent with the view that certain cultural attributes affect the degree to which relationships are valued in the societal and business contexts. Our study highlights the importance of considering lenders' culture when investigating the effects of lending relationships on the cost of bank loans.

Culture and the demand for non‐life insurance: Empirical evidences from middle‐income and high‐income economies*

AbstractThis paper investigates the impact of culture on non‐life insurance expenditure using a panel dataset covering 27 middle‐income countries and 40 high‐income countries in the period 1980–2014. Based on the two‐step system GMM estimator, it is found that several cultural dimensions such as masculinity, uncertainty avoidance and power distance significantly explain the spending on non‐life insurance in middle‐income countries, while masculinity is the only cultural factor that significantly explains spending on non‐life insurance in high‐income countries. Traditional drivers of the demand for non‐life insurance, such as per capita income, economic freedom and urbanization, also behave differently comparing between the two income‐based groups of countries. These findings provide useful recommendations for business firms and policymakers around the world, especially transitional economies, to promote and sustain the development of the non‐life insurance sector, which is an important engine for growth and prosperity.

Forging a Bayesian link between habitat selection and avoidance behavior in a grassland grouse

Habitat selection is a basic aspect of the ecology of many species, yet often the term is conflated or confused with both habitat preference and habitat use. We argue that each term fits within a conceptual framework that can be viewed in Bayesian terms and demonstrate, using long-term data on occupancy patterns of a grassland grouse, how prior probability profiles can be estimated. We obtained estimates by specifically focusing on whether and to what extent the Lesser Prairie-Chicken (Tympanuchus pallidicinctus) avoids anthropogenic features such as roads, powerlines, petroleum wells, fences, and buildings, in two study areas, one with denser and one with sparser incidence of features. Grouse strongly avoided large features such as outbuildings and tended to avoid tall features such as powerlines; by contrast, grouse did not or only slightly avoided low, unobtrusive features such as fences. We further examined co-location of pairs of anthropogenic features and found that certain features were avoided so strongly that avoidance distance may be shorter for other features; that is, birds were “pushed toward” some features because they are “pushed away” from others. In each case, our approach points toward a means to incorporate avoidance behavior directly into analytic studies of habitat selection, in that data on use (the posterior, as it were) could be used to infer the selection process provided data on preference (the prior, as it were) could be obtained.

The effect of daily calf stroking frequency during the postnatal period on the establishment of the human-calf relationship

ObjectiveStroking calves during the postnatal period could effectively improve human-calf relationships. The objective of this study is to examine how daily calf stroking frequency during the postnatal period affects the establishment of human-calf relationships.MethodsSix calves were stroked by a trainer for 6 minutes once daily for 5 days after birth (D1). Six calves were stroked by a trainer for 3 minutes twice daily for 5 days after birth (D2). A further four calves were stared at but not stroked as the control group. The overall stroking or staring duration was the same for all groups, at 6 min/d and 30 min over 5 days. The tests for reactions to the stationary trainer in an unfamiliar environment and avoidance distance measurements for an approaching trainer were conducted at 1 month and 3 months after the treatment.ResultsCalves in both stroking groups approached significantly closer to the stationary trainer, vocalized less, and looked at the trainer shorter than the control group at 1 month. However, at 3 months, there was no significant difference between the D1 and the control group, whereas the D2 approached significantly closer to the trainer and vocalized less, and looked at the trainer for a shorter time than the control group. For the avoidance distance, the trainer could approach closer to both stroking groups than the control at 1 month, however, there was no difference among groups at 3 months.ConclusionOur results suggested that the difference in the calf stroking procedure affected the established human-calf relationships, even though the total stroking duration was the same for all stroked calves. It is likely to be more effective to stroke more frequently than intensively when the aim is to establish better human-calf relationships within limited labor time.

Cultural imprints: Emerging market multinationals’ post-acquisition corporate social performance

Many emerging market multinational corporations (EMNCs) acquire firms in developed markets to attain advanced technology and managerial know-how. However, adopting socially responsible practices may not show immediate financial returns and thus, are potentially overlooked. Given the lack of formal institutions to enforce socially responsible practices in their home country, EMNCs have discretion in improving their post-acquisition corporate social responsibility performance (CSRP). This study extends the institution-based view on EMNCs’ internationalization and investigates how informal institutions, specifically home country cultures, affect EMNCs’ post-acquisition CSRP. Studying a sample of EMNCs’ acquisitions in the U.S., we find that EMNCs’ home country cultures exert “imprinting” effects that enable or discourage their post-acquisition CSRP. Uncertainty avoidance and power distance are positively related to the improvement of EMNCs’ CSRP, while individualism has a marginally negative relationship. Post-hoc analysis suggests that compared to manufacturing firms, service firms are more susceptible to the cultural imprinting effects.

Cultural values of parent bank board members and lending by foreign subsidiaries: The moderating role of personal traits

In this study, we investigate how the average cultural values of parent bank board members affect lending by foreign subsidiaries and how this influence is moderated by board members’ personal traits. Using a new dataset that includes information on foreign banks and their parent companies from 66 and 29 countries, respectively, we find that loan growth of foreign subsidiaries is faster when parent boards exhibit, on average, higher uncertainty avoidance and power distance but lower individualism and indulgence. Notably, the identified regularities are significantly moderated by gender, busyness, and firm ownership of parent bank board members.

National Culture and Bank Liquidity Creation

This paper investigates the relationship between national culture and cross-country variations in bank liquidity creation. We hypothesize that banks in individualistic societies create more liquidity because of risk-taking and overconfidence bias. On the other hand, a better access to soft information likely facilitates liquidity creation by banks in collectivistic societies as well. Using a sample covering 66 countries over the 2001–2014 period, we find that individualism is associated with greater bank liquidity creation. This finding is robust to several sensitivity checks. The effect of individualism is stronger for larger banks, pointing to the importance of soft information on bank lending. Additional analysis suggests that uncertainty avoidance and power distance are related to lower bank liquidity creation.

Animal welfare assessment based on Welfare Quality® criteria in a dairy farm in Turkey

This study served as a pilot to examine the practical implementation of the Welfare Quality® assessment protocol for cattle in dairy farms in Turkey. The study was carried out in the large-scale dairy farm of Ataturk University, in a free-stall-housed herd composed of Holstein, Brown Swiss and Simmental cattle. Whether the standards of the farm management programme and some of the welfare criteria chosen from the protocol were met was determined with the scoring method described in the Welfare Quality® publications. The somatic cell count (SCC) of the milk samples, and the avoidance distance and body condition score (BCS) of the animals were also determined and recorded. The body condition scores (BCS) of the Holstein, Simmental and Brown Swiss cattle were determined as 2.56, 3.16 and 3.88, respectively. Only 7% of the 53 cows had lameness, and none of the animals were evaluated as ‘resting a foot, standing on the edge of a step, displaying stepping (weight shifting) or showing reluctance to bear weight’. The animals were also evaluated based on some health indicators. The percentages of animals displaying nasal and ocular discharge were 16% and 9%, respectively. No clinical signs were recorded for hampered respiration, diarrhea or vulvar discharge. The mean SCC of the milk samples was (log 10) 4.43 cells/ml and below the European Union’s raw milk SCC threshold. In conclusion, according to the assessment based on Welfare Quality® criteria, the animal welfare level at the dairy farm of Ataturk University was scored as %70.92 and was considered to meet the relevant EU standards.

Gregarious nesting in relation to floor eggs in broiler breeders

Gregarious nesting has often been observed in laying hens, where hens prefer to visit a nest already occupied by other hens over empty nests. This may result in overcrowding of the nests which is considered a welfare issue and, moreover, can increase the economic issue of floor eggs. This study aimed to describe gregarious nesting and spatial behavior in broiler breeders and how this relates to genetic background, fearfulness and mating behavior. Five commercially available genetic lines of broiler breeders were housed in 21 pens of 550 females and 50 males (six pens for lines 1 and 2, five pens for line 3 and two pens for lines 4 and 5) during the ages 20–60 weeks. Every 10 weeks, the plumage condition and wounds were assessed of 50 random hens per pen. Avoidance distance and novel object tests were performed to assess fearfulness at four time points. Distribution of eggs over nests was observed for 6 weeks at the onset of egg production at 26 weeks of age, and use of space was recorded at four time points, while (floor) egg production was noted daily per pen. We found differences between genetic lines over time in plumage condition and prevalence of wounds. Fear of humans was highest at the earliest age tested and did not correlate with general fearfulness as assessed by the novel object test. The distribution of eggs over nests was related to genetic background and was more uneven at the earliest age compared to later ages, and a more uneven distribution was correlated with an increased percentage of floor eggs. Distribution of birds over the litter area differed between the genetic lines, and less use of the litter area was correlated with an increased fear of humans and presence of wounds, suggesting an association with aggressive mating behavior. This difference in distribution of the birds could also explain the correlation between increased presence of wounds and decreased percentage of floor eggs. It is concluded that broiler breeders do show gregarious nesting, which is affected by genetic background. Both increased gregarious nesting and wounds are related to increased floor egg percentage, which should be studied further in broiler breeder research. Genetic selection for even use of the available nests and of the litter and slatted area would therefore support both broiler breeder welfare and performance.

Effects of hatching system on the welfare of broiler chickens in early and later life

Broiler chicks usually hatch in the hatchery without access to feed and water until placement at the farm. This can affect their health and welfare negatively. Therefore, alternative strategies have been developed, for instance providing chicks with early nutrition in the hatchery or hatching eggs directly on-farm. However, information on the physical and mental welfare of chicks hatched in these systems compared to conventionally hatched chicks is limited. The aim of this study was to investigate the effects of alternative hatching systems on the welfare of broiler chickens in early and later life. A system comparison was performed with chickens that hatched conventionally in a hatchery (HH), in a system which provided light, feed, and water in a hatcher (hatchery-fed, HF), or on-farm (on-farm hatched, OH, where feed and water were available and transport of day-old chicks from the hatchery to the farm was not necessary). Chickens were reared in 3 batches, in 12 floor pens per batch (approximately 1,155 animals per pen), with a total of 12 replicates per treatment. Animal-based welfare indicators were assessed following standard protocols: plumage cleanliness, footpad dermatitis (FPD), hock burn, skin lesions (all at day 21 and 35 of age), and gait score (day 35). Furthermore, a set of behavioral tests was carried out: novel environment (day 1 and 21), tonic immobility, novel object, and avoidance distance test (day 4 and 35). Plumage cleanliness, hock burn, and skin lesions were affected by age but not by hatching system, with older broilers scoring worse than younger ones (P < 0.05). An effect of hatching system was only found for FPD, with the highest prevalence in HH chickens, followed by HF and OH chickens (P < 0.05). All responses measured in the behavioral tests were affected by age but not by hatching system. In later life, chickens were significantly less fearful than during the first days of life. The results indicate that conventionally hatched chickens scored significantly worse for FPD, whereas, in general, hatching system seemed to have minor effects on other broiler welfare indicators.

Evaluating avoidance distance and fleeing speed of broilers exposed to aerial systems

Intensive labor chores for broiler production could be reduced by using automated systems. However, broilers’ response toward automated systems remains unclear. The experiments were conducted to determine the avoidance distance (AD) and the fleeing speed (FS) of 4-8 weeks old broilers toward two aerial systems, a rail with a dummy arm and a drone, operated at different speeds (0.2-1.2 m/s), and heights (0.3-1.8 m) in a commercial broiler house. The broiler AD to a human assessor was also determined for comparison. Results show that the overall mean and standard error (SE) of broiler AD were 63±3 cm for the assessor, 58±1 cm for the rail, and 85±1 cm for the drone. As bird age increased from week 4 to week 8, broiler AD reduced significantly from 82 to 45 cm for the rail but showed no significant change for the drone. As the operational speed increased, broiler AD significantly increased from 54 cm (0.2 m/s) to 62 cm (0.4 m/s) for the rail, and from 81 cm (0.4 m/s) to 89 cm (1.2 m/s) for the drone. As the operational height increased, broiler AD increased from 54 cm (0.3 m) to 57 cm (1.5 m) for the rail and 81 cm (1.2 m) to 88 cm (1.8 m) for the drone. Overall mean and SE of broiler FS were 0.21±0.01 m/s for the rail and 0.65±0.01 m/s for the drone. As bird age increased from week 4 to week 8, the mean broiler FS decreased from 0.47 to 0.07 m/s for the rail and from 0.84 to 0.16 m/s for the drone. Increasing operational speed from 0.2 to 0.4 m/s for the rail and from 0.4 to 1.2 m/s for the drone significantly increased the mean FS from 0.18 to 0.24 m/s and from 0.52 to 0.78 m/s, respectively. Increasing the height of the rail from 0.3 to 1.5 m decreased the broiler FS from 0.27 to 0.16 m/s. However, increasing drone height from 1.2 to 1.8 m retained a similar FS. The outcomes of this study can help to better understand the interaction of broilers with aerial systems and provide insights into the optimization of robotic operational strategies while maintaining good broiler welfare production.

Gentle interactions with restrained and free-moving cows: Effects on the improvement of the animal-human relationship.

The animal-human relationship is essential for farm animal welfare and production. Generally, gentle tactile and vocal interactions improve the animal-human relationship in cattle. However, cows that are fearful of humans avoid their close presence and touch; thus, the animal-human relationship first has to be improved to a point where the animals accept stroking before their perception of the interactions and consequently the animal-human relationship can become positive. We tested whether the animal-human relationship of cows fearful of humans is improved more effectively by gentle interactions during restraint, allowing physical contact from the beginning, or if the gentle interactions are offered while the animals are free to move, giving them more control over the situation and thus probably a higher level of agency and a more positive perception of the interactions. Thirty-six dairy cows (median avoidance distance 1.6 m) were assigned to three treatments (each n = 12): gentle vocal and tactile interactions during restraint in the feeding rack (LOCK); gentle vocal and, if possible, tactile interactions while free in the barn (FREE); routine management without additional interactions (CON). Treatments were applied for 3 min per cow on 10 d per fortnight for 6 weeks (i.e., three periods). Avoidance and approach behaviour towards humans was tested before the start of the treatment period, and then at 2-week intervals. The recorded variables were reduced to one score by Principal Component Analysis. The resulting relationship score (higher values implying a better relationship with humans) increased in all groups; the increase was stronger in FREE than in CON, with the increase in LOCK being not significantly different from the other treatment groups. Thus, we recommend that gentle interactions with cows should take place while they are unrestrained, if possible.

Spatial Presence, Performance, and Behavior between Real, Remote, and Virtual Immersive Environments.

Spatial presence encompasses the user's ability to experience a sense of "being there". While particular attention was given to assess spatial presence in real and virtual environments, few have been interested in measuring it in telepresence situations. To bridge this gap, the present work introduces a study that compares the execution of a task in three conditions: a real physical environment, a remote environment via a telepresence system, and a virtual simulation of the real environment. Following a within-subject design, 27 participants performed a navigation task consisting in following a route while avoiding obstacles. Spatial presence and five related factors (affordance, enjoyment, attention allocation, reality, and cybersickness) were evaluated using a presence questionnaire. In addition, performance measures were gathered regarding environment recollection and task execution. The evaluation also included a behavioral metric measured by obstacle avoidance distance extracted from participants' trajectories. Results indicated a higher presence in the real environment, along with the best performance measures. No difference was found in spatial presence between the remote and the virtual conditions, although a higher degree of affordance and enjoyment was attributed to the virtual environment, and a higher degree of reality was attributed to the remote environment. The number of collisions was found to be lower in the remote condition compared to the virtual condition. Similarly, the avoidance distance was also bigger (and almost similar) in the real and the remote environments compared to the virtual environment indicating a greater caution of participants. These cues highlight that the behavior of participants in the remote condition was closer to their behavior in the real situation than it was in the virtual condition. Furthermore, positive correlations were found between the reality factor and two of the three performance measures, as well as with the behavioral metric. This suggests that the degree of physical existence of the space in which participants operate can influence their performance and behavior.

Environmental Awareness in Different European Cultures

Abstract The 28 countries of the European Union represent a rather heterogeneous group regarding their geography, history, and national cultures. Their response to the current global challenges depends on their way of viewing the world, and that is largely influenced by their national values and beliefs. The research compares the environmental awareness in distinct country groups and identifies the components of national culture, which, by their different approaches to the environmental sustainability, influence the most. The time span of the analysis is seven years from 2012 to 2018. National culture is defined by Hofstede’s cultural dimensions, and the environmental awareness data were collected from the Eurobarometer surveys of the EU. The main findings show that the environmental awareness in the EU increases with time and is higher in indulgent, more individualistic, and more long-term oriented countries, while the level of masculinity and uncertainty avoidance or power distance did not matter. The Scandinavian countries are remarkably environmentally aware, while the other groups of countries do not differ in this respect.

Fecal Cortisol Metabolites in Dairy Cows: A Cross-Sectional Exploration of Associations with Animal, Stockperson, and Farm Characteristics.

Simple SummaryDairy cows are exposed to various potentially stressful situations in the daily farm routine, which might considerably impair their welfare and performance. On 25 German organic dairy farms, we explored associations of cows’ physiological stress levels by means of cortisol metabolite concentrations in feces (1) with different potentially influencing farm factors including human–animal contact, (2) cows’ fear behaviors towards humans, and (3) milk production and udder health. Cortisol metabolite levels were decreased on farms that did not separate diseased cows, possibly reflecting less regrouping stress. Levels were also lower on farms with straw yards compared to raised cubicles, and on farms with generous compared to suboptimal lying space, underlining the importance of resting comfort for cattle. Increased human–animal contact was associated with decreased cortisol metabolite levels. However, against expectations, levels were higher, when the farm provided concentrate feed by hand and habituated young cows to milking, requiring specific experimental investigations to draw conclusions on causal associations.To date, little is known about influences on cows’ physiological stress levels on farms. The present study explored associations of fecal cortisol metabolite concentrations (FCM) with (1) farm factors including human–animal contact, (2) cows’ fear behaviors towards humans, and (3) milk production and udder health, involving 25 dairy farms and repeated fecal samples (n = 2625) from 674 focal cows. Farm factors via interviews and observations, avoidance distance (AD) and qualitative behavior assessment (QBA) during a human–animal interaction were recorded. Milk yield and somatic cell scores (SCS) were calculated from milk recordings. Levels of FCMs were in general relatively low. No associations with AD and milk yield could be detected. Correlations between FCMs and QBA and SCS were significant, but on a low level. Against expectations, FCMs were higher, when the farm provided concentrates by hand and habituated heifers to milking, in part possibly due to reversed cause–effect relations. Decreased FCM levels were found on farms that did not separate diseased cows, possibly due to the avoidance of social stress following changes in group structure. Additionally, straw yards compared to raised cubicles and generous compared to suboptimal lying space were associated with decreased levels, underlining the importance of comfort around resting. Moreover, FCMs were decreased with increased human contact time per cow. The different associations detected in this study provide a basis for further experimental investigations that moreover might provide insights into causal relationships.

UNDERSTANDING CULTURAL DETERMINANTS OF MOOCs OFFERING: A CROSS-COUNTRY STUDY

Massive Open Online Courses, also known as MOOCs, figure as the main trend in the international educational market in recent years, characterized by the offer of free, open access and global courses. Although many current studies address issues like design, quality and acceptance of these courses, little attention has been given regarding cultural aspects that could influence this global open learning movement. Therefore, the aim of this paper is to investigate cultural determinants of MOOCs offering, through a cross-country analysis. To this end, four cultural factors proposed by Hofstede were considered. Through the multivariate regression analysis, we evaluated the relation between these factors and the number of MOOCs offered in each country. The results show that Individualism presents a significant and positive effect on MOOCs offering. Power Distance, Uncertainty Avoidance and Masculinity dimensions of culture do not present significant effect on MOOCs offering. This means that although individuals from countries with higher rates of Masculinity and lower levels of Uncertainty Avoidance and Power Distance are more likely to attend online courses, universities in these countries are not necessarily the ones offering more MOOCs. The results of the study may be useful to support the implementation of strategies for the diffusion and internationalization of MOOCs.

Short- and long-term effects of rearing dairy calves with contact to their mother on their reactions towards humans.

In this Research Communication we address the hypotheses that reduced contact with humans during the first week of life would impair the relationship of dairy calves reared in dam-calf-contact systems to humans in comparison with artificially reared animals, but that this difference would vanish over time. Artificially reared calves (Artificial) that had been separated from their mother within 12 h after birth were bottle-fed with colostrum for 5 d and thereafter sucked milk from an automatic milk feeder. Animals reared with dam-calf contact (Dam-contact) were kept in the calving pen with their dam for 5 d, and then had permanent access to the cow barn and thus to their dam. Calves were weaned at an age of 12 weeks and kept in young stock groups mixed of both treatments until integration into the cow herd. We tested the animals' relationship with humans by assessing the animals' responses towards an unfamiliar person in an avoidance distance (AD) test in the home environment at 4 weeks of age, at 15 months and at 33 months. In calves, we additionally measured AD in a novel arena after a stationary person test. Artificial animals had lower AD, i.e. showed lower level of fear, than Dam-contact calves. However, the AD in Dam-contact calves decreased with increasing number of days they experienced assistance for suckling. Further, there was no significant difference in later ages. In conclusion, gentle human contact in combination with feeding during the first 5 d of life improved calves' relationship to humans leading to differences between the two treatments as well as within the Dam-contact calves. Potential effects under different conditions regarding quantity and quality of human-animal interactions need further research.
