The rate of wool growth (weight of wool produced per unit time), determined in seven sheep subjected to four levels of food intake, ncreased 400-600 per cent. from the lowest to the highest level of feeding and this change was reflected in both the mean length and in the mean diameter of the fibres, the relationship between these variables being characteristic of the individual sheep. The fibre diameter distribut!ons were also affected, the individual fibres responding up to the limit of their capacities in proportion to their cross-sectional areas.

Australian Merino

SUMMARYEstimates of the incidence of coarse fibres and medullation were made from 1014 bales of Merino greasy wool, from the five major wool-selling centres in Australia. A full range of wool types was represented from the fault-free spinners types to the burry, dusty, inferior topmakers' types. The wool consisted of 36 processors' lots ranging from 1 to 120 bales.The mean diameter of the 36 lots was 20·7 ± 5·3 μ 2·4% of the fibre population exceeded 30 μ the incidence of medullation was 1·1%.Mean diameters of the individual lots ranged from 14·7 to 25·3 μ Twenty-one of the 36 lots had coefficients of variation of mean fibre diameter which exceeded 23%. The range of clean, oven-dried yield was 49·4–69·1%. The between-lot variation in fibre medullation was 0–3·1%.It is concluded that fibre coarseness as measured by diameter was not a problem in the wide range of wool sampled. However, the incidence of medullation is an increase on previous estimates and should be a cause of concern to breeders.

The sulphur content of wool from 66 Peppin Merino wethers maintained together at pasture was measured in midside staples representing 49 weeks growth. The distribution of sulphur values was normal with a mean of 3�43 % and a range of 3�08-3�92 %. The sulphur content of the wool was inversely related to wool production among these sheep. There were no significant differences in the relationship when wool production was expressed as fleece weight index (F.W.I.), i.e. clean fleece weight/body weight (r = -0�48), as clean fleece weight (r = -0�42), or as wool growth per unit area of skin (r = - 0�37). The mean sulphur content of wool from sheep with the 10 highest values for F.W.I. was 3�27%, compared with a mean of 3 �55% sulphur for wool from sheep with the 10 lowest values for F.W.I.

The aim of the present study was to evaluate the relationship between BMI and tooth decay in a population of Iranian children. In this cross-sectional descriptive/analytical study, 1482 children were selected from kindergartens and preschool centers in Kerman, Iran. The children underwent examination of deciduous teeth (using the dmft index) after determination of height and weight for calculation of BMI. The relationship between BMI (after adjustment for age) and dmft was determined using Poisson’s regression model. The mean of dmft in children with normal BMI was 1.5-fold that in subjects with extra body weight. Age had a significant effect on dmft. In addition, dmft was higher in boys compared to girls. The results of the present study showed that caries rate in the deciduous teeth of 3–6-year-old children decreases with an increase in body weight.

Background Many studies have investigated the adherence to professional codes of ethics by nurses. However, no study has explicitly examined the relationship between workload and adherence to professional codes of ethics among Iranian nurses. Objective This study aimed to explore the relationships between workload and adherence to professional codes of ethics among a sample of Iranian nurses. Materials and Methods A cross-sectional descriptive study was conducted on 213 nurses who were randomly selected from the different wards of Shahid Beheshti Hospital of Kashan, Iran. Data collection instruments included a personal characteristics questionnaire, the Nursing Ethics Questionnaire, and the National Aeronautics and Space Administration Task Load Index. The Chi-square, the Spearman correlation coefficient, the Kruskal–Wallis, and Mann–Whitney U tests were used to analyze the data. Results A majority of nurses were females (77.5%), married (79.3%), and permanently employed (55.4%). The mean of the overall perceived workload and adherence to professional codes of ethics were 76.36 ± 13.64 and 13.98 ± 2.58, that were at high and moderated level, respectively. Spearman correlation test showed no significant correlation between perceived workload and adherence to professional codes of ethics ( r = 0.03, P = 0.6). A significant difference was found between the mean scores of adherence to professional codes of ethics in nurses working in different departments ( P < 0.001). Conclusion Participating nurses perceived high levels of workload but their mean adherence to professional codes of ethics was at a moderate level. The perceived workload was indirectly correlated with adherence to professional codes of ethics.

Objective: This study was conducted to evaluate the relationship between hopelessness and perceived social support levels of parents with children with congenital heart disease (CHD). Material and Methods: This cross-sectional study was conducted with parents of children who underwent surgery for CHD, and data were collected from 100 parents who agreed to participate in the study. A descriptive information form for the sociodemographic characteristics of the parents, “Beck Hopelessness Scale (BHS)” and “Multidimensional Scale of Perceived Social Support (MSPSS)” were used to collect the data. Data were analysed using descriptive statistics and Spearman’s correlation tests. Results: The mean score of the hopelessness level of the parents participating in the study was 6.15±4.23, and the mean perceived general social support score was 69.55±15.47. There was a significant negative correlation between the hopelessness levels of mothers and social support (SS) received from the family, from significant others, and general SS scores. There was a significant positive correlation between the hopelessness levels of the mothers and the SS level received from the family (p<0.05). Conclusion: In this study, the parents of children with CHD have low levels of hopelessness and perceived SS levels are high. Moreover, the relationship between hopelessness and perceived SS levels varies according to the sex of the parents. In our study, the SS level of mothers had a higher effect on the hopelessness level. It is recommended that the SS levels of the parents of children with CHD should be increased to help them cope with hopelessness.

The aim of our study was to evaluate the morphogenetic variability as a marker of smoking dependency in adult smokers versus controls and to investigate the presence and the degree of morphogenetic variability difference between male and female smokers versus same gender controls. The cross-sectional study evaluated 241 smokers and 185 nonsmoker individuals as controls. We analyzed 17 homozygous recessive characteristics (HRC). There was a significant difference in the individual variations of 17 HRCs between the controls and smokers (??2=61.400, p<0.001; for females ??2=79.440, p<0.001; for males ??2=84.972, p<0.001). The mean values of HRCs significantly differed between smokers and controls (MV?SEM(Controls) -4.79?0.13, MV?SEM(Smokers) -5.70?0.12; p<0.001). For males, presence of 6/17 (35.29% genetic homozygosity) HRCs (OR=6.12) was to the certain degree predictor for smoking dependency. Higher degree of genetic homozygosity, changed variability and male gender, might be some among potential numerous factors that could have impact on smoking development and dependence.

PurposeThe purpose of this paper is twofold: first, to examine whether inspirational leadership of heads of specialized medical units is related to individual ambidexterity of their dependent physicians; and second, to study the possible mediating role of organizational learning capability (OLC) in the relationship between inspirational leadership and individual ambidexterity.Design/methodology/approachStructural equation modeling was used on a sample of 194 medical specialists from Spanish public hospitals.FindingsResults show that inspirational leadership is positively related to individual ambidexterity among healthcare physicians. In addition, the results of the study revealed that the relationship between inspirational leadership and individual ambidexterity is mediated by conditions that facilitate learning, namely, OLC.Research limitations/implicationsThis study uses cross-sectional data, which do not guarantee causality relationships among the examined variables.Practical implicationsThe results of this paper suggest first that heads of healthcare units should inspire followers to achieve both exploration and exploitation. Second, it is also necessary to consider that inspirational leaders promote those conditions that facilitate learning, which should be particularly taken into account to enhance both physician’s exploration and exploitation.Originality/valueIn stressing an evident gap in the relationship between leadership and ambidexterity at the individual level, this paper attempts to advance in the leadership literature by revealing how the action or power of moving the intellect or emotions, and enhancing enthusiasm and confidence, empowers physicians to both explore and exploit knowledge. The results also indicate that the inspiration transmitted by the heads of medical services, facilitate physician’s perceived learning conditions which, in turn, fosters their individual ambidexterity.

Dyadic Model

A dyadic approach to studying relationship dynamics yields considerably more insights than examining each partner separately. Yet relatively little research has examined dyadic models of commitment, despite commitment being essential to relationship persistence. Accordingly, we tested a dyadic version of the investment model of commitment. In two cross-sectional studies of couples and one experiment, we tested the role of partner investments and perceived partner investments as novel antecedents of commitment. Studies 1 and 2 demonstrated that greater partner investments were related to greater levels of individuals’ commitment, while controlling for individuals’ own satisfaction with, investments in, and alternatives to the relationship. Study 3 revealed that partner-reported investments predicted commitment independent of perceived partner investments. The findings advance the investment model beyond the individual level, emphasizing the need to examine dyadic elements of relationships.

Purpose Boredom at work is associated with negative consequences, therefore it is important to investigate whether employees engage in job crafting behaviors that reduce boredom and what are the individual differences associated with these behaviors. The paper aims to discuss these issues. Design/methodology/approach A questionnaire study was designed to examine the mediating role of job crafting in the relationship between conscientiousness and emotional stability and boredom among 252 employees (Study 1) and in the relationship between Machiavellianism and psychopathy and boredom among 216 employees (Study 2). Findings The results showed that conscientiousness is negatively related to work-related boredom. This relationship is mediated by job crafting. Neuroticism and psychopathy are positively associated with boredom at work, but these relationships are not mediated by job crafting behaviors. Research limitations/implications The study was based on self-reported measures, which might raise questions of common-method bias, and the research samples contained mostly women and young employees, which raises questions about generalizability of our findings. At the same time, the cross-sectional design does not allow causal inferences. Practical implications Organizations can select employees based on their personality for jobs that predispose to boredom and give them enough autonomy to be able to craft them. Moreover, they can identify employees who need support to manage their boredom and include them in job crafting interventions. Originality/value Traditionally, boredom at work has been considered as resulting from characteristics of tasks and jobs. The findings indicate that some employees can make self-initiated changes to their work in order to reduce their boredom and possibly its negative consequences.

Abstract The present study aimed to (a) establish the frequency of consumption of red meat and eggs; (b) determine serum ferritin levels (μg/l); and (c) establish the relationship between serum ferritin and the consumption of red meat and eggs. In Colombia during 2014–2018, an analytical study was conducted in 13 243 Colombian children between the ages of 5 and 17 years, based on cross-sectional data compiled by ENSIN-2015 (Encuesta Nacional de la Situación Nutricional en Colombia-2015) on serum ferritin levels and dietary consumption based on a questionnaire of the frequency of consumption. Using simple and multiple linear regression, with the serum ferritin level as the dependent variable and the frequency of consumption as the main explanatory variable, the crude and adjusted partial regression coefficients (β) between serum ferritin levels and consumption were calculated. The frequency of habitual consumption of red meat was 0⋅49 (95 % CI 0⋅47, 0⋅51) times/d. The frequency of habitual egg consumption was 0⋅76 (95 % CI 0⋅74, 0⋅78) times per d. The mean serum ferritin level in men was 41⋅9 (95 % CI 40⋅6, 43⋅1) μg/l and in women, 35⋅7 (95 % CI 34⋅3, 37⋅7) μg/l (P < 0⋅0001). The adjusted β between the consumption of red meat and eggs and serum ferritin levels were β = 3⋅0 (95 % CI 1⋅2, 4⋅7) and β = 2⋅5 (95 % CI 1⋅0, 3⋅9) for red meat and eggs, respectively. In conclusion, red meat and eggs are determinants of serum ferritin levels in Colombia and, therefore, could be considered public policy options to reduce anaemia and Fe deficiency.
