Job Satisfaction & Human Behavior

A worker's attitude and job satisfaction are vital for an organization to achieve its goals.

Job Satisfaction

An affective attitude reflecting like or dislike toward various job-related factors, including pay and relationships.

Worker Attitude Effects

Attitudes significantly predict behavior. Positive job attitudes correlate with constructive actions and superior customer service.

Worker Performance

The quality of output relative to time and cost; satisfaction-performance is a complex two way relationship.

Study Notes

  • A vector-valued function of a real variable is a function $\overrightarrow{r}: \mathbb{R} \rightarrow \mathbb{R}^n$ which assigns a vector $\overrightarrow{r}(t)$ of $\mathbb{R}^n$ to each real number $t$.
  • Example of a vector-valued function: $\overrightarrow{r}(t) = (t^2 + 1, \cos(t), e^t)$ is a vector-valued function of a real variable with values in $\mathbb{R}^3$.

Components

  • If $\overrightarrow{r}(t) = (x_1(t), x_2(t), \dots, x_n(t))$, then the functions $x_i: \mathbb{R} \rightarrow \mathbb{R}$ are the components of $\overrightarrow{r}$.
  • Example: for $\overrightarrow{r}(t) = (t^2 + 1, \cos(t), e^t)$, the components are $x_1(t) = t^2 + 1$, $x_2(t) = \cos(t)$ and $x_3(t) = e^t$.

Limit

  • The limit of a vector-valued function $\overrightarrow{r}(t)$ as $t$ approaches $a$ is the vector $\overrightarrow{L}$ such that each component of $\overrightarrow{r}(t)$ approaches the corresponding component of $\overrightarrow{L}$ as $t$ approaches $a$. $$\lim_{t \to a} \overrightarrow{r}(t) = \overrightarrow{L} = (L_1, L_2, \dots, L_n)$$
  • If and only if $$\lim_{t \to a} x_i(t) = L_i \quad \text{for each } i = 1, 2, \dots, n$$
  • Example: $$\lim_{t \to 0} (t^2 + 1, \cos(t), e^t) = (1, 1, 1)$$

Continuity

  • A vector-valued function $\overrightarrow{r}(t)$ is continuous at $t = a$ if the following conditions are met:
    • $\overrightarrow{r}(a)$ is defined.
    • $\lim_{t \to a} \overrightarrow{r}(t)$ exists.
    • $\lim_{t \to a} \overrightarrow{r}(t) = \overrightarrow{r}(a)$.
  • Equivalently, $\overrightarrow{r}(t)$ is continuous at $t = a$ if each of its components is continuous at $t = a$.
  • Example: $\overrightarrow{r}(t) = (t^2 + 1, \cos(t), e^t)$ is continuous everywhere in $\mathbb{R}$ because each of its components is.

Derivative

  • The derivative of a vector-valued function $\overrightarrow{r}(t)$ is defined as: $$\overrightarrow{r}'(t) = \lim_{h \to 0} \frac{\overrightarrow{r}(t + h) - \overrightarrow{r}(t)}{h}$$
  • If $\overrightarrow{r}(t) = (x_1(t), x_2(t), \dots, x_n(t))$, then $$\overrightarrow{r}'(t) = (x_1'(t), x_2'(t), \dots, x_n'(t))$$
  • Example: If $\overrightarrow{r}(t) = (t^2 + 1, \cos(t), e^t)$, then $\overrightarrow{r}'(t) = (2t, -\sin(t), e^t)$.

Integral

  • The integral of a vector-valued function $\overrightarrow{r}(t)$ is defined as: $$\int \overrightarrow{r}(t) dt = \left( \int x_1(t) dt, \int x_2(t) dt, \dots, \int x_n(t) dt \right)$$
  • Example: $$\int (t^2 + 1, \cos(t), e^t) dt = \left( \frac{t^3}{3} + t + C_1, \sin(t) + C_2, e^t + C_3 \right)$$
