Doctor of Philosophy / Psychological Sciences / Patrick A. Knight / Satisfaction with work-family balance is a relatively new construct that differs from other work-life constructs in several ways: it is not focused on conflict between work/family domains, does not include cross-domain transfer processes, has no directional implications, and is not multidimensional. The current study has three purposes: 1. Examine work-family balance issues for both blue-collar and white-collar employees, as the literature has focused mainly on white-collar employees. 2. Examine relationship between technology and satisfaction with work-family balance. 3. Assess how role salience influences satisfaction with work-family balance. Participants were recruited and compensated for completing a 60 item online survey via Qualtrics. Blue-collar participants were recruited from manufacturing industries, while no industry was specified for white-collar employees. The sample consisted of 210 participants (105 blue-collar, 105 white-collar). Several checks were included throughout the survey to ensure data quality. Two hierarchical regression analyses were conducted. The first regression revealed that boundary control and autonomy predict satisfaction with work-family balance, while employee type and boundary interruptions do not. Boundary control, family identity, and stress significantly predicted satisfaction with work-family balance in the second regression, while boundary interruptions, work identity, hours worked, and technology use did not. Results indicate white-collar workers have higher satisfaction with work-family balance, lower stress, and lower turnover intentions compared to blue-collar workers. Results also reveal that technology use to complete work outside of work hours is significantly and positively related to stress. Nearly half of participants report feeling expected to utilize technology to complete work outside of work hours. In addition, while it was hypothesized that those higher on family identity would have lower satisfaction with work-family balance when they used technology outside of work hours, worked longer hours, and had more frequent boundary interruptions than would those lower on family identity, the opposite effect was found for each of these variables. Implications of the study include: 1. Organizations may improve employee satisfaction with work-family balance by increasing autonomy and boundary control. 2. Employees may improve satisfaction with work-family balance by taking time to de-stress from work and limiting use of technology to complete work outside of work hours.

The aim of the research was to look at the motivations behind white-collar crime and, by means of the insights gained, allow businesses to achieve a better understanding of these motivations and the possible loopholes that exist with respect to white-collar crime. Empowered which such knowledge, businesses fraud mitigation polices and approaches are enhanced; which contribute towards sustained operations and increased shareholder value by reduce losses. Face-to-face interviews were held with 29 white-collar offenders imprisoned at the Johannesburg Medium Correctional Centre in Gauteng, South African. Data was collected from these interviews and grouped into themes that related to the research questions. An action plan was formulated to assist business in their fight to eliminate and reduce the impact of commercial crime. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

Bakgrund och problem: Ett välkänt ekonomiskt styrmedel som används av företagsledare för att motivera anställda till att utföra prestationer som ligger i linje med företagets mål är belöningssystem. Belöningssystem fungerar olika i olika branscher och måste anpassas efter typ av verksamhet och anställda. Ett relativt outforskat område är industribranschen, här utförs ofta kärnprocessen av arbetarna på golvet vilket gör det intressant att se hur ett industriföretag jobbar med belöningssystem mot dessa typer av anställda och identifiera kritiska områden för belöningssystemets funktion mot arbetare då detta är ett ostuderat område. Syfte: Syftet med denna studie är att bidra med ökad förståelse om hur industriföretag jobbar med belöningssystem gentemot arbetare och vad dessa arbetare har för erfarenheter av detta system. Metod: En kvalitativ fallstudie är utförd på företaget Atlas Copco Power Technique Nordic som är verksamma inom industribranschen. Åtta respondenter har intervjuats genom semi-strukturerade intervjuer. Studien har anammat en abduktiv forskningsansats  Slutsats: Atlas Copco Power Technique Nordic använder sig av många olika belöningar i olika former för att motivera sina anställda, en kombination av icke-monetära belöningar är den främsta nyckeln för att skapa motivation hos anställda. Det framkommer att de monetära belöningarna exklusive lön inte har betydande påverkan på arbetarnas motivation och vilja att prestera. Det visar sig även att mål och rättvisa har en betydande roll vad gäller arbetarnas positiva inställning till belöningssystemet. / Background and problem: A well-known financial instrument used by business leaders to motivate employees to perform in line with the company's goal is the reward system. Reward systems work differently in different industries and must therefore be adapted to the type of business and type of employees in an organization. A relatively unexplored area is the industrial industry. Here the core processes are often performed by the blue-collar workers which makes it interesting to see how an industrial company works with reward systems towards these types of workers and identify critical areas for the reward system's function towards blue-collar workers as this is an unstudied area. Purpose: The purpose of this study is to contribute to an increased understanding of how industrial companies work with reward systems towards blue-collar workers and what experience these workers have of this system. Method: A qualitative case study has been carried out at the company Atlas Copco Power Technique Nordic, which is active in the industrial industry. Eight respondents were interviewed through semi-structured interviews. The study has adopted an abductive research approach  Conclusion: Atlas Copco Power Technique Nordic uses many different rewards in different ways to motivate its employees, and the combination of non-monetary rewards is the main key to creating motivation in employees. It appears that the monetary rewards excluding wages have no meaningful effect on blue collar worker’s motivation and desire to perform. It also appears that goalsetting and justice play a significant role in terms of blue collar worker’s positive attitudes towards the reward system.

ABSTRACT: Study One - Our objective was to characterize mature range cows based on intake and grazing activity. Starting in the early spring of 2013, 4 experiments were conducted. First, mature range cows (n = 137) were fitted with radio frequency identification tags (RFID) and placed in a dry-lot pen equipped with GrowSafe® technology to monitor DMI of alfalfa hay. These data were then used to assign cows a residual feed intake (RFI) value utilizing the National Research Council (NRC) (1996) model to predict intake of beef cattle. Cattle with negative and positive RFI were characterized as low-intake and high-intake, respectively. In addition, the following data were also recorded: weight (kg), age (mo), days pregnant (d), and body condition score (BCS). Second, 30 mature range cattle were selected from the first trial and fitted with pedometers for 7 d to monitor activity with step counts and estimate distance traveled. Third, mature range cows (n = 25) selected from the first trial were fitted with global position system (GPS) collars, and placed on pinyon-juniper rangeland from 20 June 2014 to 17 September 2014. Forth, mature range cows (n = 28) were fitted with GPS collars, and placed on ponderosa pine rangeland from 17 September 2014 to 15 October 2014. Distance traveled, slope, distance from water, elevation data were collected from both GPS trials. Low-intake and high-intake cows consumed 9.3 and 12.2 kg/d, respectively (P < 0.0001). Low-intake cattle became pregnant sooner (P = 0.002) than high-intake cattle (average of 16 d sooner). Cattle age (mo) equaled 90 and 98 for low- and high-intake cows, respectively (P = 0.04). Weight, predicted DMI, and BCS did not differ between groups (P > 0.06). Step counts for low- and high-intake animals were 5839 and 5383 ± 2089, respectively (P = 0.61), and estimated distance traveled was 4.31 and 5.35 ± 1.66 km d⁻¹ for low- and high-intake animals, respectively (P = 0.77). Low-intake cows (6.23 km d⁻¹) traveled farther (P = 0.005) each day than high-intake cows (5.84 km d⁻¹) on pinyon-juniper rangelands, and high-intake cows utilized (P = 0.013) steeper slopes. No differences were detected (P ≥ 0.06) for distance traveled, distance from water, and elevation for cows grazing ponderosa pine rangeland). However, low-intake cattle preferred (P = 0.046) steeper slopes on ponderosa pine rangeland than high-intake cattle. These results indicate that low-intake animals may travel farther on some rangelands and rebreed earlier. Study Two - Commercial grade heifers (n = 173) born and raised on the University of Arizona's V bar V Ranch from 2012 to 2014 were fitted with radio frequency identification tags (RFID) and placed in a drylot equipped with Growsafe® technology (8 bunks) for 60 d in 3 groups based on birth year in order to calculate DMI, residual feed intake (RFI), ADG, G:F, and residual gain (RG). Birth date, birth weight, weaning weight, age at start of trial, initial trial weight, and final trial weights were also recorded. Residual feed intake scores were utilized to place heifers in one of three treatment groups, low-, medium-, and high-intake. Reproductive and calf data were collected on heifers born in 2012. Means for birth date, birth weight, weaning weight, initial weight, final weight, and ADG did not differ among the three treatments. Residual gain for low-, medium-, and high-intake heifers were different (P < 0.05) at 0.07, 0.00, and -0.07 kg d⁻¹, respectively. Low-intake cattle had an improved (P < 0.05) GF ratio of 0.19 when compared to the medium- and high-intake heifers with ratios of 0.15 and 0.13 (P > 0.05), respectively. Differences (P <0. 05) in DMI were detected with low-, medium, and high-intake heifers consuming 5.2, 6.2, and 7.5 kg d⁻¹, respectively. No differences were detected for pregnancy rate, calving rate, percent bred artificial insemination (AI), percent bull calves, calf birth weight, and calf birth date among treatments (P > 0.05).Study Three - Commercially available GPS tracking collars for cattle are cost prohibitive to most researchers. This paper will present a low-cost alternative to those collars (Knight GPS tracking collars), and provide detailed instructions on where to source materials and how to fabricate inexpensive GPS tracking collars. In addition, the two types of collars will be compared in a study where Brangus cattle (n = 8) were each fitted with LOTEK® 3300 and Knight GPS tracking collars for 31 d beginning 14 March 2015 at the Chihuahuan Desert Rangeland Research Center (CDRRC) 37 km north of Las Cruces, New Mexico. Location, slope, distance from water, distance traveled and elevation were recorded every 10 min. A record of GPS fix rate was logged. No differences were detected (P≥0.369) between collar types for location, slope, or distance from water. However, there was a tendency (P = 0.08) for Knight collars to report a lower estimate for distance traveled at 6171 m d⁻¹ compared to Lotek collars at 7104 m d⁻¹. Fix rate was greater (P≤0.001) for Lotek collars compared to Knight collars at 99.9 and 66.2%, respectively. Study Four - Previously characterized commercial cows (n = 26) were placed into either high (positive RFI) or low intake (negative RFI) groups. On 14 May 2015, 13 high- and 13 low-intake cows were fitted with modified igotU GT-120® GPS logging collars. Cattle were then placed on rangeland for 120 d. The first 30 d period animals transitioned from desert shrubland to pinyon-juniper. From 31 to 60 d, animals grazed pinyon-juniper rangeland. Next, during days 61 to 90, animals transitioned from pinyon-juniper to ponderosa pine, and the last 30 d were spent in ponderosa pine. Time periods will be referred to as month 1, 2, 3, and 4 for days 0 to 30, 31 to 60, 61 to 90, and 91 to 120, respectively. Location, slope, distance from water, elevation, and time spent close to water were recorded every 10 min. No differences were observed in the utilization of elevation or distance traveled, or distance from water (P>0.05). Low intake animals used a higher maximum slope (P < 0.05) during month 3, but slope utilization differences were not detected for other portions of the trial (P > 0.05). Study Five - Hereford sires (n = 35) with 7 or more cow offspring on the University of Arizona V bar V ranch in Rimrock, Arizona were tested at Neogen laboratories in Lincoln, NE for an Igenity Gold genetic profile. Their residual feed intake (RFI), ADG, tenderness, marbling score, milk production percent choice, yield grade, fat thickness, ribeye area, heifer pregnancy rate, stayability, maternal calving ease, birthweight and docility were estimated. Sires were given a genetic RFI score based on their RFI profile and placed into one of three intake groups, low (< 0.5 SD), medium (± 0.5 SD) and high (> 0.5 SD). Performance traits of cow offspring (n = 839) from those sires were also compared based on their sire's intake group. No differences (P > 0.05) were detected among sire intake groups for ADG, tenderness, marbling score, percent choice, yield grade, fat thickness, ribeye area, heifer pregnancy rate, stayability, maternal calving ease, birthweight and docility. Residual feed intake differed among groups (P < 0.05), and high intake cattle had more estimated milk production compared to low intake animals (P < 0.05). Cows from low intake sires were born later in the year (P < 0.05). High intake cattle had a higher (P < 0.05) birthweight and survived longer (P < 0.05) in the herd when compared to low and medium intake cows. Genetic RFI and expected milk production were moderately to highly correlated.

Problem  Following the expanded competition when it comes to attraction and retention of skilled workers, hence white-collar workers, organizations need to better adapt to the rapid changes in the labor market. Due to the lack of knowledge about the recent Generation Z and their perceptions and values regarding work, the Person-Organization (P-O) fit has been applied in order to gain a deeper knowledge of what attracts and retains individuals of Generation Z, in order for companies to better meet their needs.   Purpose Due to the lack of research done on Generation Z, the purpose of this study is to gain a greater understanding of the values and perceptions of Generation Z and how they operate in the white-collar business sector. Moreover, this creates a greater insight for organizations in order to help them better target the right talent pool and gain a greater understanding of Generation Z that has come to change the labor market.   Method In order to gain a greater knowledge and insight about Generation Z, a qualitative study has been performed to better understand the perception of this Generation. In-depth interviews have been conducted with Generation Z that have or are currently operating in the white-collar business sector in order to meet the purpose of this study. Semi-structured interviews were conducted in order to allow for a fruitful discussion of their values and perceptions and the likely impacts they consider when joining an organization.   Conclusion Generation Z indicated that certain aspects are to consider in the decision-making process of applying or taking a job. Indeed, their own values, beliefs and work-personal life matter to a great extent and is to be matched with the company. This study comes to the result of six determined factors influencing this decision-making process: small enterprises, flexibility trust and freedom, work/private life environmental factors, organizations values/ethics, do what they love, digital natives.

A Leishmaniose visceral (LV) é uma zoonose de ampla distribuição, e atualmente, representa sério problema para a saúde pública. Nas Américas, agente etiológico é a Leishmania (Leishmania) infantum, transmitido, principalmente, pela picada da fêmea de Lutzomyia longipalpis (Diptera: Psychodidae) infectada. O cão doméstico é considerado o principal reservatório da doença. No Brasil, embora sejam utilizadas diversas estratégias para o controle da doença, a mesma persiste e continua sendo dispersada. Devido ao fato dessas estratégias apresentarem dificuldades, por sua complexidade e custo de seus protocolos, faz-se necessária a reavaliação da eficácia e viabilidade das mesmas em estudos teóricos. O uso da modelagem matemática tem auxiliado essas avaliações. Após a adaptação de um modelo já existente para LV, foi avaliada a eficácia do uso de intervenções em cães, como coleira impregnada com deltametrina, vacina e sacrifício, em diferentes coberturas e de modo regular e contínuo. Como base, foram utilizados dados característicos de áreas endêmicas do Brasil. Os cinco melhores cenários simulados foram capazes de diminuir as prevalências de cães e humanos, consideravelmente. Por ordem de eficácia são: 1) Coleira em 75% dos cães; 2) Sacrifício de 90% dos cães; 3) Coleira em 50% dos cães; 4) Sacrifício de 75% dos cães; 5) Vacina (eficácia vacinal de 80%) em 75% dos cães. Algumas medidas foram capazes de gerar cenários parecidos ou semelhantes, de prevalências em cães e humanos, quando utilizadas em diferentes coberturas de cães. Visto que a dinâmica da LV apresentou-se altamente dependente dos parâmetros relacionados ao vetor, e, uma vez que a coleira impregnada com inseticida interfere nestes parâmetros, o uso da mesma em cães se mostra como uma medida eficaz no controle da LV. Entretanto, o efeito repelente da coleira se mostrou eficaz quando se encoleira grande cobertura de animais. Sendo assim, todas medidas enfocadas em cães, simuladas no presente estudo, são capazes de controlar a prevalência da LV nas populações de cães e humanos, desde que utilizadas em alta cobertura de animais. / Visceral Leishmaniasis (VL) is a zoonosis of worldwide distribution, representing serious public health problem. At the Americas, the etiologic agent is Leishmania (Leishmania) infantum, transmitted, mainly, by the bite of the female of infected Lutzomyia longipalpis (Diptera: Psychodidae). The natural hosts are rodents, edentulous, marsupials, primates and canids, with the domestic dog considered the main reservoir of the disease. In Brazil, although several strategies to control the disease are used, the VL still persist and are dispersing. Due to the fact of the control for LV presents difficulties because its complexity and cost of its protocols, becomes necessary reassessment of their effectiveness and viability in theoretical studies. The mathematical modeling has helped these reassessments. After the adaptation of an existing model for LV, was evaluated the impact of the use of interventions in dogs, like as deltamethrin-impregnated collar, vaccine and sacrifice. Were used, as the basis, characteristic datas from endemic areas of Brazil. The top five simulated measures were: collar in 75% of dogs, sacrifice of 90% and 75% of the seropositive dogs, collar in 50% of the dogs and vaccine (vaccine effectiveness 80%) in 75% of seronegative dog. There was observed that different measures, to both prevention and control, resulted in similar scenarios of dogs and humans prevalence. The repellent effect of the collar was effective since a extensive coverage animals be conduced. The LV dynamics showed to be highly dependent on the parameters related to the vector, and because of this the use of deltamethrin-impregnated collar can be the best measure, to interfere directly in the both mortality of the same and inhibition of the bite. Thus, these measures, focused on dogs, in this study, are able to significantly decrease the populations of infected dogs and humans, since be used for high coverage of animals and are regularly implemented with the same intensities and for prolonged period.

This dissertation is a legal and cultural history of personal debt in mid-nineteenth-century Moscow region. Historians have shown how the judicial reform of 1864 dismantled an old legal apparatus that was vulnerable to administrative interference and ultimately depended upon the tsar's personal authority, replacing it with independent judges, jury trials, and courtroom oratory. But as many legal scholars will agree, political rhetoric about law and high-profile appellate cases fail to capture the full diversity of legal phenomena. I therefore study imperial Russian law in transition from the perspective of individuals who used the courts and formed their legal strategies and attitudes about law long before the reform. I do so through close readings of previously unexamined materials from two major archives in Russia: the Central Historical Archive of Moscow and the State Archive of the Russian Federation, including the records of county- and province-level courts and administrative bodies, supplemented by the records of the charitable Imperial Prison Society. I also analyze the relevant legislation found in imperial Russia's Complete Collection of the Laws. Specific topics covered in the study include the cultural and social profiles of creditors and debtors and of their relations, the connection between debt and kinship structures and strategies, the institution of debt imprisonment and its rituals, various aspects of court procedure, as well as the previously unstudied issue of white-collar crime in imperial Russia. I have found that debt was ubiquitous in Russian life, as in other pre-industrial societies in which cash was scarce, incomes erratic, and formal credit institutions insufficient. It was also overwhelmingly personal, relying heavily on kinship, acquaintance, and the reputations of borrowers and lenders. My research contradicts the conventional view of Russian society at mid-century as a system of predominantly separate and closed estates. The system of private credit centered in Moscow connected merchants, civil servants, and the landowning gentry, and even wealthy peasants, some of whom lived or owned property in far-away provinces (privately-owned serfs were of course subordinate to their landlords in matters involving property). The credit network was sufficiently extensive and diverse to place an additional burden on Russia's already overworked legal system. The central theme of my study is the engagement of ordinary Russian lenders and borrowers of varying wealth and status, male and female, with each other and with the legal system (and through it with the state) during a crucial turning point in Russia's social and political history. My research also questions the dominant notion of a closed system of inquisitorial justice in pre-reform courts. The cases I examined reveal the pre-reform legal process as messy, incomplete, polyphonic, and open to extra-legal influences, including those of tsarist administrative officials. Private individuals retained significant discretion and initiative both according to the law and in practice, beginning with the way a debt transaction was formalized and ending with the decision to imprison a debtor or to commit an insolvent to a criminal trial. I therefore argue that pre-reform law with all its faults was a site of conflict, cooperation, and negotiation among diverse individuals seeking to protect and promote their property interests and between private persons and government officials. I show the law to be a key tool for Russia's propertied classes for asserting their own rights against other private individuals and/or against the state. Thus, I reinterpret the relationship between individuals and the administration, modifying the commonly held view of the Nicholaevan bureaucracy as a monolith imposing itself on the tsar's subjects. As the only study of imperial civil law in practice, this dissertation offers unique evidence on the operations of state and society in Russia at the key period of the Great Reforms, as well as establishes a basis for understanding subsequent legal developments.
