This two-part study was undertaken to determine if increased heat stress was associated with the use of Tyvek® suits at a given temperature and workload, and the effect of ambient temperature on the level of heat stress experienced within the suit. In the first part of the study the independent variables were: ambient condition (22.2° C and 50% rh vs. 32.2° C and 60% rh) and workload (20% vs. 40% of maximum Vo2). The eight subjects ranged in age from 27 to 63, with equal numbers of men and women. Treadmill walking was used to simulate workload. Each experimental run lasted 45 minutes. In the second part, workload was fixed at 40% of maximum Vo2 and the suits were not worn. All other conditions were the same. Subjects (female, age 32; male, age 32; male, age 63) were chosen from the original eight. Results for the two parts were compared. Wearing the suit increased the heat stress upon an individual. Rectal temperature increased by an average of .17° C, heart rate by 16 bpm, average heat stored by 54 kcals, and average sweat loss by .73 liters/m2. Ambient temperature appeared to have a positive effect on the level of heat stress experienced within the suit. There were confounds, indicating a need for further study. It is recommended that ACGIH guidelines for work-rest ratio determination be followed, providing one adds 6°–11° C to the calculated ambient WBGT before entering the chart. These findings agree with the TLV WBGT Correction factors for clothing provided in the 1991 ACGIH guidelines on heat stress and the findings of Paull and Rosenthal (1987).

Abstract Pregnant sows, especially during late-gestation, may be susceptible to heat stress due to increased metabolic heat production and body mass. Therefore, the study objective was to determine the thermoregulatory and physiological responses of sows exposed to increasing ambient temperature (TA) at 3 reproductive stages. In 3 repetitions, 27 multiparous sows (parity 3.22±0.89) were individually housed and had jugular catheters placed 5.0±1.0 d prior to the experiment. To differentiate between reproductive stages, sows were categorized as open (not pregnant, n=9), mid-gestation (59.7±9.6 days pregnant, n=9), or late-gestation (99.0±4.8 days pregnant, n=9). During the experiment, sows were exposed to 6 consecutive 1 h periods of increasing TA (period 1, 14.39±2.14°C; period 2, 16.20±1.39°C; period 3, 22.09±1.87°C; period 4, 26.34±1.39°C; period 5, 30.56±0.81°C; period 6, 35.07±0.96°C), with 1 h transition phases in between each period. Respiration rate (RR), heart rate (HR), skin temperature, and vaginal temperature (TV) were measured every 20 min and the mean was calculated for each period. At the end of each period, blood gases, leukocytes, and red blood cell counts were measured. Overall, RR and HR were greater (P≤0.04; 45.6% and 12.9%, respectively) in late-gestation versus mid-gestation sows. Compared to mid-gestation and open sows, TV tended to be greater (P=0.06) during period 4 (0.18°C and 0.29°C, respectively) and period 5 (0.14°C and 0.18°C, respectively) in late-gestation sows. Blood O2 increased (P< 0.01; 18.1%) for all sows with advancing period, regardless of reproductive stage. Late-gestation sows had reduced (P=0.02; 16.1%) blood CO2 compared to mid-gestation sows, regardless of period. In summary, late-gestation sows appear to be more sensitive to increasing TA as indicated by increased RR, HR, TV, and blood O2, and reduced blood CO2 when compared to mid-gestation or open sows. This change in O2 and CO2, due to increasing RR and heat stress sensitivity of late-gestation sows, may suggest an alteration to the acid-base balance, leading to respiratory alkalosis.

In this study, there are results that contradict the theory which states that the higher the level of training and motivation, the employee's performance should increase.  In this study, training had no effect and motivation had no positive effect. This study aims to determine the effect of training and work motivation on employee performance in Kopiloka 3.0.  The population in this study were all employees at Kopiloka 3.0, which amounted to 15 people with a sample of 15 people using saturated sampling.  The data analysis technique in this study used SPSS 24 software, which consisted of data quality test, classical assumption test, multiple regression analysis, and hypothesis testing. By using multiple regression analysis, the results of the study show that training has no effect on employee performance.  Motivation has a significant effect on employee performance.  Simultaneously (together) the independent variables of training and motivation have an effect on employee performance.

Hasil Penelitian menujukkan bahwa Harga daging sapi, harga daging kambing, dan pendapatan konsumen mampu menjelaskan variabel permintaan sebesar 80,2%. Sedangkan sisanya sebesar 19,8% dijelaskan oleh variabel lain yang tidak disertakan pada persamaan. secara parsial dari ketiga variabel bebas (independent) terdapat dua variabel (harga daging sapi dan harga daging kambing) berpengaruh tidak nyata dan positif terhadap permintaan. Variabel pendapatan konsumen berpengaruh nyata dan positif artinya bahwa setiap penambahan satuan pendapatan konsumen akan menambah permintaan daging sapi.   ABSTRACT This study aims to determine the behavior of respondents as consumers of beef households in Pematangsiantar City, to determine the behavior of the beef industry in Pematangsiantar City and to analyze the factors of beef demand in Pematangsiantar City. Researchers goals 1 and 2 use survey methods and descriptive analysis methods, Researchers aim 3 using data analysis methods used is a multiple linear regression model that is processed with the SPSS 22 program with hypothesis testing consisting of coefficients (R2), F test and t test. The results showed that the price of beef, goat meat prices, and consumer income is able to explain the demand variable of 80.2%. While the remaining 19.8% is explained by other variables not included in the equation. partially from the three independent variables, there are two variables (beef prices and mutton prices) that have no significant and positive effect on demand. The variable of consumer income has a significant and positive effect, meaning that each additional unit of consumer income will increase beef demand.

This research, based on stakeholder theory and the national cultural dimensions, aims to test the influence of foreigners on board and its size on Integrated Reporting (IR) practices. The analysis is based on a sample of 1,058 European companies from 18 different countries, who adopted or not the IR for the year 2015, and it relies on a Logit. The dependent variable is a dummy (presenting or not the IR) and the independent variables are represented by the board characteristics (foreigners and size). The impact of the critical mass on the presence of foreigners and the cultural dimension on the basis of directors’ nationality was tested relying on the masculinity/femininity dimension of Hofstede. Besides, the directors’ country of origin was considered, namely if they belong to the major European countries presenting a wider IR diffusion. The relationship between foreigners on board and IR is found to be negative. This means that companies with at least one foreigner are less inclined to adopt IR. The results show that the boards with more of three foreign administrators have a major propensity to adopt the IR. The membership of the directors in countries with a feminist culture also has a positive effect.
