A pattern of quark mass hierarchy and CP violation within the framework of low energy supersymmetry is described. By assuming some discrete symmetry among the three families, the quarks of the third family obtain masses at tree level. The second family obtains masses radiatively at one-loop level due to the soft breaking of the family symmetry. At this level, the first family remains massless by some degeneracy conditions of the squarks. As a result of R parity violation, the sneutrino vacuum expectation values are nonvanishing. CP violation occurs through the superweak sneutrino exchange. This picture is consistent with the experiments on the flavor-changing neutral current.

The present study examined the relations among sex, work-family conflict, and psychological distress in 78 Canadian police officers (50 men and 28 women). The average age of the officers was 36.1 yr. ( SD= 8.0), and nearly one-third of the respondents had been in policing 16 years or more. Ordinary least-squares regression was conducted to examine the association of Psychological Distress scores, as measured by the K6, with four types of work-family conflict: Time-based Work-to-Family Conflict, Time-based Family-to-Work Conflict, Strain-based Work-to-Family Conflict, and Strain-based Family-to-Work Conflict. Being single and having higher perceived Strain-based Work-to-Family Conflict were associated with greater scores on Psychological Distress. No statistically significant sex differences emerged in the self-reported type or direction of work-family conflict or in the factors associated with Psychological Distress.

PurposeThis study investigates the impact of the CEO's financial literacy on family SMEs' growth, as well as the moderating role of the generational stage on this relationship.Design/methodology/approachThe study is based on survey data of Spanish private family firms and utilizes a second source of data, the SABI database by Bureau Van Dijk. The authors run ordinary least squares regressions and use both the base and the partition approaches to test the hypotheses.FindingsThe analysis reveals a positive association between the CEO's financial literacy and firm growth. However, this relationship is not uniform across generations. The CEO's financial literacy-firm growth relationship becomes weaker for first- and third or subsequent-generation family firms while becoming stronger for second-generation family firms.Originality/valueThis study adds the financial literacy of the CEO as a novel individual-level determinant of family firm growth. It also shows that CEOs do not always use their financial literacy to its full potential to foster growth. More specifically, the extent to which financial literacy leads to firm growth is found to be conditional on the generational stage of the family SME. The obtained findings are valuable for family SMEs intending to hire a new CEO, encouraging the financial literacy of the current CEO and educating the next generation of family members.

This study aimed to analyze the needs and status of family support programs at the Gwanak-gu Family Center in the context of COVID-19. An online survey targeting Gwanak-gu residents between the ages of 20 and 60 was conducted between September and October 2021. Descriptive statistics, a chi-squared test, a t-test, and a one-way ANOVA were used to analyze the data gathered from 506 participants. The results of this study are as follows. First, after the COVID-19 pandemic, the numbers of male, single (unmarried), and single-person household participants increased. Second, demand for “me”-related programs, such as self-discovery, self-management, and hobbies, was generally high. Third, demand for “me”-related programs was the highest among the group that had never previously used the Family Center. Fourth, although women with children in preschool were highly satisfied with the non-face-to-face method, no significant difference was found in the satisfaction between the face-to-face and non-face-to-face methods. The results also showed that most respondents did not have a strong preference for either the face-to-face or non-face-to-face methods. Fifth, in educational programs, there was a high preference for the non-face-to-face method, while in programs emphasizing communication, experience, and exchange, there was a high preference for the face-to-face method. The findings indicate that it is necessary to adjust program themes and operation methods by tailoring them to the characteristics and needs of the target population and considering regional characteristics when developing new programs.

The moments in reinforced concrete during bending with torsion were determined, the new first hypothesis of linear deformations and its filling of the diagram during bending with torsion for the analytical second functional as a function of three functions - an exponent, a straight line and a parabola curve. A simple new method is found (from the family of mesh methods) and a summed function of additional deplanation is proposed. The new second hypothesis of angular deformations and its filling of the diagram in reinforced concrete during bending with torsion is constructed. The analytical first general undefined functional is a function of functions, as well as transitions, operations between functions. At the same time, a spatial triple integral of arguments from longitudinal deformations for the first hypothesis was obtained, as well as the third and fourth functionals (indefinite and definite) from moments (bending and twisting) with the projection of the coefficients of the diagram of "deformations - stresses" of compressed concrete and the filling coefficients of the diagrams of compressed concrete for their shoulders to the neutral axis for a field of small squares. The bending and torque moments from the compressed area of concrete and working reinforcement are determined (folded for their levels or expanded into algebraic functions from the synthesis of the computational model of reinforced concrete blocks). In this case, we have new functionals (from the first to the fourth functional), proposed hypotheses (first and second), as well as cross sections (from small squares) to a spatial crack. There are also jumps (cracks) lateral, normal, etc., from the first - third stage of average deformations of concrete and working reinforcement.

Introduction:Colorectal cancer is known as the third leading cause of death from cancer in the world and the second cause of death in developing countries. Family care can positively affect the patient's general health system. The present study was conducted to determine and compare the effect of family-centered and client-centered training approaches on the life quality of individuals with digestive ostomy. Methods: This is a semi-experimental study conducted on 60 individuals. The individuals participating in the present study were chosen from either those with digestive ostomy or their attendants. The participants fulfilled the requirements (criteria) for entering the present study. For conducting the training procedure, both groups received family-centered or client-centered training. Two months later, the quality of life of the individuals with digestive ostomy was measured once more. The data were then analyzed in SPSS ver.21 by using chi-squared test, paired t-test, and independent t-test. Results: According to the findings of the present study, there is no significant difference between the family-centered and the client-centered groups in terms of demographic features. By investigating the mean changes of both groups, There was a significant difference between quality of life score and spiritual-psychological aspect of scores before and after the intervention in the family-centered group. Conclusion: The findings of the present study showed that family-centered education can increase the quality of life for people with gastrointestinal ostomy. This study concluded that family-centered education can be considered an effective intervention in people with gastrointestinal ostomy.

(1) Background: System-level data on waiting time in the outpatient setting in Hungary is scarce. The objective of the study was to explore self-reported waiting time for an appointment and at a doctor’s office. (2) Methods: An online, cross-sectional, self-administered survey was carried out in 2019 in Hungary among a representative sample (n = 1000) of the general adult population. Chi-squared test and logistic regression analysis were carried out to explore if socioeconomic characteristics, health status, or residence were associated with waiting times and the perception of waiting time as a problem. (3) Results: Proportions of 90%, 41%, and 64% of respondents were seen within a week by family doctor, public specialist, and private specialist, respectively. One-third of respondents waited more than a month to get an appointment with a public specialist. Respondents in better health status reported shorter waiting times; those respondents were less likely to perceive a problem with: (1) waiting time to get an appointment (OR = 0.400) and (2) waiting time at a doctor’s office (OR = 0.519). (4) Conclusions: Longest waiting times were reported for public specialist visits, but waiting times were favorable for family doctors and private specialists. Further investigation is needed to better understand potential inequities affecting people in worse health status.

Purpose The purpose of this paper is to investigate the association between family wealth, positive outlook, and support from significant others, including parents and friends, on self-efficacy and happiness. Design/methodology/approach The impact of family wealth, social support, and positive outlook on self-efficacy and one’s own happiness is analyzed through the partial least squared method. Findings There are five essential points that can be drawn from the statistical results. First, parents’ support tends to be more important than friends’ support for individuals’ happiness. Second, individuals that receive more support from parents tend to develop a higher level of self-efficacy. Third, individuals that are in a less wealthy family tend to develop a higher level of self-efficacy. Fourth, parents’ support plays a more important role in developing a higher level of self-efficacy for individuals that are in a less wealthy family than for individuals that are in a wealthier family. Finally, the positive link between happiness and self-efficacy was stronger for individuals in a wealthier family than for individuals in a less wealthy family. Research limitations/implications In particular, although individuals in a wealthier family tend to exhibit a lower level of self-efficacy, and happiness alone had no significant impact on self-efficacy, happiness significantly promoted self-efficacy more for individuals in a wealthier family than for individuals in a less wealthy family. Social implications In conclusion, the results from this research provide essential recommendations for individuals regarding the approach to happiness and self-efficacy. The results indicated how significant the role of parents’ support is in one’s happiness and that support from parents is more important for one’s self-efficacy and happiness than support from friends. Furthermore, individuals should be aware that money is not the ultimate answer for happiness and self-efficacy. Individuals in less wealthy families were able to enjoy a higher level of self-efficacy given that they were receiving sufficient support from their parents. Originality/value This study found that although individuals in a wealthier family tend to exhibit a lower level of self-efficacy, and happiness alone has no significant impact on self-efficacy, happiness significantly promote self-efficacy more for individuals in a wealthier family than for individuals in a less wealthy family. However, in the less-wealthier family, parents play more significant role and can generate high level of self-efficacy for their children.

The children who grew up in two-parent households for their entire childhood earn more than the other children reared in non-intact parental families. The causal effect of growing up in a twoparent household on the child’s adult earnings is the hourly earnings difference between the children who grew up in intact families and their counterparts raised by parents who have ever divorced, separated, or widowed, holding relevant factors constant and accounting for endogeneity issues. I identify the causal effect by using the following specification strategies. First, I control the parental income and educational attainment, along with the child’s demographic characteristics (gender, age, race, region, and tenure), to disentangle the childhood family intactness effect from the other parental influence. Second, I take into account the unobserved clan-specific heterogeneity, such as family traditions and genetic characteristics, by fitting the clan fixed effects (FE) models. Third, I use two instrumental variables (IVs), the state divorce rate and the no-fault divorce law effectiveness, for the endogenous childhood family structure and adopt the two-stage least squares (2SLS) approach to further alleviate the omitted variable bias. The estimates are around 0.16, suggesting that the children who grew up in a twoparent household earn about 16% more in adulthood than their counterparts from non-intact families, other things equal. The effect goes through three channels. The child’s education, health, and marital behavior are the mediator variables representing the three observable channels through which childhood family intactness affects the child’s adult earnings. The effect of growing up in a two-parent family on the child’s adult earnings varies with parental income and education. The effect is larger and more significant for sons than for daughters. The heterogeneous pattern of the effect is consistent with the parental utility maximization model’s predictions. Growing up in a two-parent household not only has a positive and significant effect on the child’s adult earnings in absolute values, but it also encourages intergenerational relativeearnings improvement. An intact childhood family lowers the probability of the intergenerational relative-earnings worsening by 6.72% and increases the probability of the intergenerational relative-earnings improvement by 6.67%.

The Newton secant method is a third-order iterative nonlinear solver. It requires two function and one first derivative evaluations. However, it is not optimal as it does not satisfy the Kung-Traub conjecture. In this work, we derive an optimal fourth-order Newton secant method with the same number of function evaluations using weight functions and we show that it is a member of the King family of fourth-order methods. We also obtain an eighth-order optimal Newton-secant method. We prove the local convergence of the methods. We apply the methods to solve a fourth-order polynomial arising in ocean acidifications and study their dynamics. We use the data of CO2 available from the National Oceanic and Atmospheric Administration from 1959 to 2012 and calculate the pH of the oceans for these years. Finally we further investigate the long-run implications of CO2 emissions on alkalinity of seawater using fully modified ordinary least squares (FMOLS) and dynamic OLS (DOLS). Our findings reveal that a one-percent increase in CO2 emissions will lead to a reduction in seawater alkalinity of 0.85 percent in the long run.

The thesis is devoted to the analysis of electroweak one-loop corrections to processes of production of scalar quarks of the third family at the Large Hadron Collider (LHC) in the context of the minimal supersymmetric extension of the Standard Model (MSSM). Third family squarks are are predicted to be among the lightest supersymmetric particles, hence they could be among the first signals of new physics to be detected at the LHC. Moreover, a very light stop (with a mass of the same order of the top mass) might play a relevant role within a cosmological model of electroweak baryogenesis. A precise analysis of one-loop corrections to processes of production of stop and sbottom particles and the determination of theoretical predictions to be tested against LHC data are therefore mandatory to understand the properties of these particles. The EW NLO corrections to the most meaningful observables related to these processes (differential and total cross sections) have been calculated and the dependence on supersymmetric parameters of the considered observables has been analysed. The considered processes are: 1) PP -> gg -> stop-antistop (sbottom-antisbottom); 2) PP-> bg -> stop-chargino. In both cases the analysis has been performed within various mSUGRA scenarios. For this purpose three C++ codes which exploit Monte Carlo techniques for the integration of cross sections have been developed. For the stop-antistop production case the diagonal production shows a total cross section of the order of 10 picobarns in some scenarios which predict a light stop; electroweak corrections, however, are of the order of few percent for every scenario considered; through the definition of the partial rates it is possible to obtain correction near to 10% in the high invariant mass region. The analysis of the dependence of one-loop corrections on mSUGRA parameters has been performed and it has been verified that the dependence is quite mild (variations up to 4%). In the case of sbottom production the total cross sections are generally smaller than 1pb and the one-loop corrections are not very sizable. As far as the parametric dependence is concerned, for diagonal production of light sbottom an interesting dependence on the parameter tg(beta) has been found in a particular scenario. For the stop-chargino production process the total cross sections are of the order of the picobarn in scenarios where stop and charginos are not too massive. The one-loop corrections are of the order of few percent and, due to the small cross sections in the considered scenarios, they are unfortunaltely quite difficult to observe at the LHC; the analysis through the partial rates predicts higher corrections, though difficult to detect. Due to these results, the parametric analysis has been performed at tree level, where the observables depend on a limited number of supersymmetric parameters: the strongest dependence has been found to be on the stop mixing angle and on the supersymmetric parameter mu. The analysis of stop production processes within scenarios of electroweak baryogenesis has been performed in both cases. For the case of diagonal production of light stop-antistop pairs, the electroweak one-loop effect on the total cross section has been found to be quite mild. Due to the small stop mass the total cross section is however of the order of 10pb. Therefore, through the analysis of partial rate it is possible to predict effects of the order of 10% with a still detectable cross section. In the stop-chargino case, the total cross section has been found to be smaller than 1pb even in the lightest configuration, and the one-loop correction is 2%.
La presente tesi consiste nell'analisi delle correzioni elettrodeboli a 1 loop di alcuni processi di produzione di quark scalari della terza famiglia al Large Hadron Collider nell'ambito dell'estensione supersimmetrica minimale del Modello Standard (MSSM). Gli squark della terza famiglia sono particolarmente importanti perché si prevede che siano fra le particelle supersimmetriche più leggere, e per questo motivo potrebbero essere fra i primi segnali di nuova fisica ad essere osservati all'LHC. Inoltre, uno stop particolarmente leggero (con una massa dello stesso ordine di quella del top) potrebbe giocare un ruolo rilevante nell'ambito di un modello cosmologico di bariogenesi elettrodebole. Una precisa analisi delle correzioni a 1 loop dei processi di produzione di stop e sbottom con la determinazione di previsioni teoriche da verificare sperimentalmente ad LHC è quindi fondamentale per cercare di comprendere le proprietà di queste particelle. In questa tesi vengono calcolate le correzioni sui principali osservabili legati a questi processi (sezioni d'urto differenziali e totali) e viene analizzata la dipendenza dai parametri supersimmetrici degli osservabili considerati. I processi analizzati sono: 1) PP -> gg -> stop-antistop (sbottom-antisbottom); 2) PP -> bg -> stop-chargino. In entrambi i casi l'analisi è stata effettuata nel contesto di diversi scenari mSUGRA. Sono stati sviluppati per questo scopo tre codici in C++ che si avvalgono di tecniche di Monte Carlo per l'integrazione delle sezioni d'urto. Nel caso del processo di produzione di stop, si è verificato che per alcuni scenari che prevedono uno stop leggero, la produzione diagonale ha una sezione d'urto totale dell'ordine della decina di picobarn; le correzioni elettrodeboli però sono dell'ordine di qualche punto percentuale per tutti gli scenari considerati; tramite la definizione delle cosiddette rate parziali è possibile ottenere correzioni vicine al 10% nella regione di alte masse invarianti. E' stata poi eseguita un'analisi di come gli effetti a un loop dipendono dai parametri mSUGRA, verificando che la dipendenza è poco apprezzabile (variazioni del 4%). Nel caso di produzione di sbottom le sezioni d'urto sono generalmente inferiori al picobarn e le correzioni a 1 loop rimangono abbastanza limitate. Per quanto riguarda la dipendenza parametrica, per produzione diagonale di sbottom leggeri c'è una interessante dipendenza dal parametro tg(beta) in un particolare scenario supersimmetrico. Nel caso del processo di produzione di stop-chargino la sezione d'urto è dell'ordine del picobarn nei casi che prevedono stop e chargini non eccessivamente massivi. Anche in questo caso le correzioni a 1 loop sono di qualche punto percentuale, difficilmente visibili a LHC a causa delle basse sezioni d'urto negli scenari considerati; l'analisi delle rate parziale consente di ottenere correzioni maggiori, ma difficilmente osservabili. A causa della scarsa visibilità del processo, l'analisi parametrica è stata effettuata a livello albero, dove gli osservabili dipendono da un numero limitato di parametri supersimmetrici: la dipendenza maggiore risulta essere per l'angolo di mixing dello stop e dal parametro supersimmetrico mu. Per quanto riguarda l'analisi dei processi di produzione di stop nell'ambito di scenari di bariogenesi elettrodebole, nel caso di produzione diagonale di stop leggeri, l'effetto a 1 loop è scarso, ma data la piccola massa dello stop che determina una sezione d'urto dell'ordine della decina di picobarn, l'analisi della rate parziale permette di prevedere effetti dell'ordine del 10%. Nel caso di stop-chargino la sezione d'urto risulta essere inferiore al picobarn anche nella configurazione più leggera e la correzione a 1 loop è del 2%.

Predictive design analytics is a new paradigm to enable design engineers to extract knowledge from large-scale, multi-dimensional, unstructured, volatile data, and transform the knowledge and its trend into design decision making. Predictive, data-driven family design (PDFD) is proposed as one of the predictive design analytics methods to tackle some issues in family design. First, a number and specifications of product architectures are determined by data (not by pre-defined market segments) in order to maximize expected profit. A trade-off between price and cost in terms of the quantity and specifications of architectures helps to set the target in the enterprise level. k-means clustering is used to find architectures that minimize within architecture sum of squared errors. Second, a price prediction method as a function of product performance and deviations between performance and customer requirements is suggested with exponential smoothing based on innovations state space models. Regression coefficients are treated as customer preferences over product performance, and analyzed as a time series. Prediction intervals are proposed to show market uncertainties. Third, multiple values for common parameters in family design can be identified using the expectation maximization clustering so that multiple-platform design can be explored. Last, large-scale data can be handled by the PDFD algorithm. A data set which contains a total of 14 million instances is used in the case study. The design of a family of universal electronic motors demonstrates the proposed approach and highlights its benefits and limitations.

Background: Maternal mental health problems, most often depression and anxiety, remain a major public health concern during the antenatal and postnatal periods. Some studies reported that high level of self-efficacy in pregnant women might improve maternal prenatal care. This study aimed to investigate the relationship between family support and self- efficacy among pregnant women in Yogyakarta. Subjects and Method: This was a cross-sectional study conducted at Kotagede I Community Health Centre, Yogyakarta from October 2017 to July 2018. A total of 30 primigravida dan multigravida women with the third trimester of gestational age was selected for this study. The dependent variable was self-efficacy of pregnant women. The independent variable was family support. The study subjects were selected by accidental sampling. The primary data were collected using family support and maternal confidence questionnaires. The data were analyzed by chi-square. Results: A total of 93.3% of pregnant women had strong family support. The majority of pregnant women possessed high levels of self-efficacy (90%). Good family support increased the self-efficacy of pregnant women (OR= 113.40; 95% CI= 6.26 to 2054.00; p <0.001). Conclusion: Good family support increases the self-efficacy of pregnant women.

Background: In 2015, the prevalence of stunting among children under five years old in Indonesia was 36.4%. It means that more than a third or around 8.8 million children under five years old height is below the standard for their age. This stunting is above the threshold set by WHO of 20%. The prevalence of stunting / stunting for Indonesian under five is the second largest in the Southeast Asia region after Laos, which reached 43.8%. This study aimed to determine the effect of family role on stunting among children under five years old. Subjects and Method: A cross-sectional was enrolled by 242 of 615 families with children under five years old in Bojong Jaya Village, Karawaci, Tangerang, Banten. The dependent variable was stunting. The independent variables were knowledge, family income and parenting style. The data collection was carried out by measuring height, in-depth interview, and questionnaire. The data were analyzed using Chi-square test. Results: The percentage of the stunting incidence was 20.2%. Family income (OR= 2.31; 95% CI= 1.19 to 4.47; p= 0.012) and parenting style (OR= 2.68; 95% CI= 1.36 to 5.31; p= 0.004) were associated with stunting incidence and they were statistically significant. There was a significant relationship between knowledge on the incidence of stunting (OR= 2.80; 95% CI 1.41 to 5.53; p= 0.002), and it was statistically significant. Conclusion: There is a relationship between family income, parenting style, and knowledge on the incidence of stunting among children under five years old. There needs to be a comprehensive program in building family resilience and multisector empowerment to increase family income, maternal education and knowledge of maternal nutrition to reduce the incidence of stunting.

Chronic diseases affect the quality of life of families of sick people on the level of their physical, economic, mental, and subjective well-being. The aim of the paper is two-folded: a) to determine the economic and social consequences of the child's illness for families and b) to identify the factors that may influence the origin and development of asthma in the child population. The data come from a survey we carried out on a sample of parents with children who are treated in the Children's Speleotherapy Sanatorium in Ostrov near Macocha (a total sample of 201 respondents). We checked for any association by use of correlation analysis, Kruskal-⁠Wallis and Chi-square test. More than half of the families reported that the child's illness negatively influences the involvement in the labour market, families show an increase in financial costs associated with rehab and a financial loss during the care of a sick child. One third of the children’s patients has problems with missing classes at school, the average absence is 8 weeks in the school year, and every tenth child has difficulty in establishing social contacts. Analyses of external factors in relation to asthma show the effect of education on smoking in the family, but did not confirm the effect of age and mother's education on the birth weight of the child or the type of birth. From the results, it is clear that asthma adversely affects the quality of life of the asthmatic child and his family. The disease is thus associated with social and psychological consequences, which limits the performance at school for children and work activities for parents and other activities. All in one, it has not only health, but also socio-economic consequences.
